Each plant can be recognized by its general shape. Nevertheless, this physiognomy is the result of a very precise structure that expresses the existence of a strong organization. The architecture of a plant depends on the nature and relative arrangement of each of its parts; it is at any given time the result of an equilibrium between endogenous growth processes and the constraints exerted by the environment. Architectural studies have been carried out for some twenty years and have led (...) to the definition of several concepts that provide a powerful tool for studying plant form. The results obtained in this field show that the architecture of a plant can be summarized by a small number of elementary structures: internode, growth unit, axis, architectural model,... In the course of ontogenesis, these structures are repeated and reveal several levels of organization that seem to be only different stages of a common process of growth and transformation. (shrink)
Shors & Matzel set up a straw man, that LTP is a memory storage mechanism, and knock him down without due consideration of the important relations among different levels of organization and analysis regarding LTP, learning, and memory. Assessing these relationships requires analysis and hypotheses linking specific brain regions, neural circuits, plasticity mechanisms, and task demands. The issue addressed by the authors is important, but their analysis is off target.
To see whether the mental and the neural have common attributes that could resolve some of the traditional dichotomies, we review neuroscientific data on the visual system. The results show that neuronal and perceptual function share a parallel and hierarchical architecture which is manifest not only in the anatomy and physiology of the visual system, but also in normal perception and in the deficits caused by lesions in different parts of the system. Based on the description of parallel hierarchical (...) class='Hi'>levels of active information processing in the visual brain, we suggest a concept of dissociable levels of perception, advocating that the phenomenal perception and recognition is realized in the functional integrity of a network of reciprocal cortico-cortical connections. The properties shared by neuronal and perceptional functions provide a basis for a neuromental monism in which both functions are attributed a causal role. (shrink)
Willard van Orman Quine once said that he had a preference for a desert ontology. This was in an earlier day when concerns with logical structure and ontological simplicity reigned supreme. Ontological genocide was practiced upon whole classes of upper-level or "derivative" entities in the name of elegance, and we were secure in the belief that one strayed irremediably into the realm of conceptual confusion and possible error the further one got from ontic fundamentalism. In those days, one paid more (...) attention to generic worries about possible errors (motivated by our common training in philosophical scepticism) than to actual errors derived from distancing oneself too far from the nitty-gritty details of actual theory, actual inferences from actual data, the actual conditions under which we posited and detected entities, calibrated and "burned in" instruments, identified and rejected artifacts, debugged programs and procedures, explained the mechanisms behind regularities, judged correlations to be spurious, and in general, the real complexities and richness of actual scientific practice. The belief that logic and philosophy were prior to any possible science has had a number of distorting effects on philosophy of science. One of these was that for ontology, we seemed never to be able to reject the null hypothesis: "Don't multiply entities beyond necessity.". (shrink)
Apparently factual disagreement on the level(s) at which selection operates often results from different interpretations of the term selection. Attempts to resolve terminological problems must come to grips with a dilemma: a narrow interpretation of selection may lead to a restricted view on evolution; a broader, less precise, definition may wrongly suggest that selection is the centre of a unified, integrated theory of evolution. Different concepts of selection, therefore, should carefully be kept apart.
This paper addresses the relationship between psychological capacities, as they are understood within cognitive psychology, and neurobiological activities. First, Lycan’s (1987) account of this relationship is examined and certain problems with his account are explained. According to Lycan, psychological capacities occupy a higher level than neurobiological activities in a hierarchy of levels of nature, and psychological entities can be decomposed into neurobiological entities. After discussing some problems with Lycan’s account, a similar, more recent account built around levels of (...) mechanisms is examined (Craver 2007). In the second half of this paper, an alternative is laid out. This new account uses levels of organization and levels of explanation to create a two-dimensional model. Psychological capacities occupy a high level of explanation relative to the cellular and molecular levels of organization. As a result, according to this model, psychological capacities are a particular way of describing the activities that occur at the cellular and molecular levels of organization. (shrink)
The debate about the levels of selection has been one of the most controversial both in evolutionary biology and in philosophy of science. Okasha’s book makes the sort of contribution that simply will not be able to be ignored by anyone interested in this field for many years to come. However, my interest here is in highlighting some examples of how Okasha goes about discussing his material to suggest that his book is part of an increasingly interesting trend that (...) sees scientists and philosophers coming together to build a broadened concept of “theory” through a combination of standard mathematical treatments and conceptual analyses. Given the often contentious history of the relationship between philosophy and science, such trend cannot but be welcome. (shrink)
In The Levels of Selection (Brandon, 1984), Robert Brandon provides a suggestive but ultimately unsuccessful attempt to use the probabilistic notion ofscreening off in providing a schema for dealing with an aspect of the units of selection question in the philosophy of biology. I characterize that failure, and suggest a revision and expansion of Brandon's account which addresses its key shortcoming.
In this paper we aim to show that phenomenal consciousness is realized by a particular level of brain operational organization and that understanding human consciousness requires a description of the laws of the immediately underlying neural collective phenomena, the nested hierarchy of electromagnetic fields of brain activity – operational architectonics. We argue that the subjective mental reality and the objective neurobiological reality, although seemingly worlds apart, are intimately connected along a unified metastable continuum and are both guided by the (...) universal laws of the physical world such as criticality, self-organization and emergence.

In this paper, using a multilevel approach, we defend the positive role of natural selection in the generation of organismal form. Despite the currently widespread opinion that natural selection only plays a negative role in the evolution of form, we argue, in contrast, that the Darwinian factor is a crucial (but not exclusive) factor in morphological organization. Analyzing some classic arguments, we propose incorporating the notion of ‘downward causation’ into the concept of ‘natural selection.’ In our opinion, this kind (...) of causation is fundamental to the operation of selection as a creative evolutionary process.

Much recent work in sociobiology can be understood as designed to demonstrate the sufficiency of selection operating at lower levels of organization by the development of models at the level of the gene or the individual. Higher level units are accordingly viewed as artifacts of selection operating at lower levels. The adequacy of this latter form of argument is dependent upon issues of the complexity of the systems under consideration. A taxonomy is proposed elaborating a series of (...) types, or grades, of hierarchically organized systems. These range from aggregative systems, in which there is no organization relevant to systemic properties, through several graded variations reflecting various degrees of functional interdependence of components, to integrated systems, which manifest component specialization and diversification as well as a subordination of component function to systemic function. It is suggested that the most complex form of organization is plausibly treated as indicative of higher level units of selection. (shrink)
We propose a theoretical model of the cerebral cortex which is based on its cellular components and integrates its different levels of organization: (1) cells have general adaptive and memorization properties; (2) cortical columns are repetitive interneuronal circuits which determine an adaptive processing specific to the cerebral cortex; (3) cortical maps effect selective combinations which are very efficient to learn basic behaviourial adaptations such as invariant recognition of forms, visually-guided hand movements, or execution of structured motor programs; (4) (...) the network between cortical areas has a global architecture which integrates successive learning experiences into coherent functions such as the human language.

We praise Arbib et al.'s Neural organization for its support of the integration of different levels of analysis, while noting that it does not always achieve what it advocates. We extend this approach into an area of neuropsychological activity in need of the structure offered by Organization at the intersection of the conflated fields of executive function and frontal lobe function.
This research examines how the fit between employees moral development and the ethical work climate of their organization affects employee attitudes. Person-organization fit was assessed by matching individuals' level of cognitive moral development with the ethical climate of their organization. The influence of P-O fit on employee attitudes was assessed using a sample of 304 individuals from 73 organizations. In general, the findings support our predictions that fit between personal and organizational ethics is related to higher (...) class='Hi'>levels of commitment and job satisfaction and lower levels of turnover intent. Ethical P-O fit was related to higher levels of affective commitment across all three ethical climate types. Job satisfaction was only associated with ethical P-O fit for one of the three P-O fit variables and turnover intentions were significantly associated with two of the ethical P-O fit variables. The most consistent effect was found for the Conventional - Caring fit variable, which was significantly related to all three attitudes assessed. The weakest effect was found for the Preconventional - Instrumental fit variable, which was only predictive of affective commitment. The pattern of findings and implications for practice and future research are discussed. (shrink)
A vision of a living code of ethics is proposed to counter the emphasis on negative phenomena in the study of organizational ethics. The living code results from the harmonious interaction of authentic leadership, five key organizational processes (attraction–selection–attrition, socialization, reward systems, decision-making and organizational learning), and an ethical organizational culture (characterized by heightened levels of ethical awareness and a positive climate regarding ethics). The living code is the cognitive, affective, and behavioral manifestation of an ethical organizational identity. We (...) draw on business ethics literature, positive organizational scholarship, and management literature to outline the elements of positive ethical organizations as those exemplary organizations consistently practicing the highest levels of organizational ethics. In a positive ethical organization, the right thing to do is the only thing to do. (shrink)
An exploratory model is presented as a heuristic to indicate how individual perceptions of corporate reputation (before joining) and corporate ethical values (after joining) generate specific individual organizational senses of fit. The paper suggests that an ethical dimension of person-organization fit may go some way in explaining superior acquisition and retention of staff by those who are attracted to specific organizations by levels of corporate social performance consonant with their ethical expectations, or who remain with them by virtue (...) of better personal ethical fits with extant organizational ethical values. Specifically, the model suggests that individual misfits that arise from ethical expectations that either exceed or fall short of perceived organizational ethical performances lead to problematic acquisition and retention behavioural outcomes.

From the advent of general purpose, Turing-complete machines, the relation between operators, programmers and users with computers can be observed as interconnected informational organisms (inforgs), henceforth analysed with the method of levels of abstraction (LoAs), risen within the philosophy of information (PI). In this paper, the epistemological levellism proposed by L. Floridi in the PI to deal with LoAs will be formalised in constructive terms using category theory, so that information itself is treated as structure-preserving functions instead of Cartesian (...) products. The milestones in the history of modern computing are then analysed through constructive levellism to show how the growth of system complexity lead to more and more information hiding. (shrink)
The use of “levels of abstraction” in philosophical analysis (levelism) has recently come under attack. In this paper, I argue that a refined version of epistemological levelism should be retained as a fundamental method, called the method of levels of abstraction. After a brief introduction, in section “Some Definitions and Preliminary Examples” the nature and applicability of the epistemological method of levels of abstraction is clarified. In section “A Classic Application of the Method of Abstraction”, the philosophical (...) fruitfulness of the new method is shown by using Kant’s classic discussion of the “antinomies of pure reason” as an example. In section “The Philosophy of the Method of Abstraction”, the method is further specified and supported by distinguishing it from three other forms of “levelism”: (i) levels of organisation; (ii) levels of explanation and (iii) conceptual schemes. In that context, the problems of relativism and antirealism are also briefly addressed. The conclusion discusses some of the work that lies ahead, two potential limitations of the method and some results that have already been obtained by applying the method to some long-standing philosophical problems.

The question of the ontological status of social wholes has been formative to the development of key positions and debates within modern social theory. Intrinsic to this is the contested meaning of the concept of emergence and the idea that the collective whole is in some way more than the sum of its parts. This claim, in its contemporary form, gives exaggerated importance to a simple truism of re-description that concerns all wholes. In this paper I argue that a better (...) way to test the ontological status of wholes is to ask whether their causal properties can be reduced to the qualities of their parts. If reduction is possible the ontological status of emergent wholes is diminished. A close analysis of William Wimsatt's definition, conceptualisation, and characterisation of emergent phenomena provides an understanding of the relationship between wholes and their parts and suggests, also, that the properties of collective phenomena of a social kind reduce to the activities of people. Social wholes and their parts reside in the same mode (or level) of organisation. This paper concludes by employing Jaegwon Kim's method of ‘functional reduction’ to demonstrate how to reduce the qualities of wholes to those of their parts. (shrink)
Neural organization: Structure, function, and dynamics shows how theory and experiment can supplement each other in an integrated, evolving account of the brain's structure, function, and dynamics. (1) Structure: Studies of brain function and dynamics build on and contribute to an understanding of many brain regions, the neural circuits that constitute them, and their spatial relations. We emphasize Szentágothai's modular architectonics principle, but also stress the importance of the microcomplexes of cerebellar circuitry and the lamellae of hippocampus. (2) Function: (...) Control of eye movements, reaching and grasping, cognitive maps, and the roles of vision receive a functional decomposition in terms of schemas. Hypotheses as to how each schema is implemented through the interaction of specific brain regions provide the basis for modeling the overall function by neural networks constrained by neural data. Synthetic PET integrates modeling of primate circuitry with data from human brain imaging. (3) Dynamics: Dynamic system theory analyzes spatiotemporal neural phenomena, such as oscillatory and chaotic activity in both single neurons and (often synchronized) neural networks, the self-organizing development and plasticity of ordered neural structures, and learning and memory phenomena associated with synaptic modification. Rhythm generation involves multiple levels of analysis, from intrinsic cellular processes to loops involving multiple brain regions. A variety of rhythms are related to memory functions. The Précis presents a multifaceted case study of the hippocampus. We conclude with the claim that language and other cognitive processes can be fruitfully studied within the framework of neural organization that the authors have charted with John Szentágothai. Key Words: cognitive maps; computational neuroscience; dynamics; hippocampus; memory; modular architectonics; neural modeling; neural organization; neural plasticity; rhythmogenesis; Szentágothai.

The information-hierarchical approach is used to analyze the evolutionary developed organization of mankind. This organization is shown to be hierarchical, from molecular hierarchical levels to the religious ones. Time cycles of each level operation are included in the greater cycle of the next level according to the specific schemes defined by the common information principle of natural system development. Time cycles of levels have duration of 1 second, 6 seconds, 42 seconds, 24 hours, 11 days, 1 (...) years, 33 year, 1,000 years, 3,000 years or 6,000 years and all together make up the mankind clock that is similar to the formerly ascertained biosphere clock. The cycles of duration from 1 second to 33 years form the human biological clock, so the information-hierarchical organization of cell metabolism manifests itself as the key mechanism of the clock. The new scientific field has been characterized. It is the management of sustainable development of the states as evolutionary developed systems with the use of information relationships of their functioning. In the case of Christianity adoption by any large ethnos the next 1,000-year cycle of the Christianity-Judaism system will start. (shrink)
Senior managers are important to the successful management of ethics in organizations. Therefore, their perceptions of organizational ethics are important. In this study, we propose that senior managers are likely to have a more positive perception of organizational ethics than lower level employees do largely because of their managerial role and their corresponding identification with the organization and need to protect the organization’s image as well as their own identity. Bycontrast, lower level employees are more likely to be (...) cynical about the organization’s ethics. In order to compare senior managers’ and lower level employees’ perceptions of ethics in the organization, we surveyed randomly selected senior managers and lower level employees in three firms. We found that perceptions of ethics in the organization differed predictably across levels, with senior managers’ perceptions being significantly more positive and lower level employees’ perceptions being more negative. Implications for practice and research are discussed. (shrink)
Philosophers and non-philosophers have been attracted to the idea that the world incorporates levels of being: higher-level items – ordinary objects, artifacts, human beings – depend on, but are not in any sense reducible to, items at lower levels. I argue that the motivation for levels stems from an implicit acceptance of a Picture Theory of language according to which we can ‘read off’ features of the world from ways we describe the world. Abandonment of the Picture (...) Theory opens the way to a ‘no levels’ conception of reality, a conception that honors anti-reductionist sentiments and preserves the status of the special sciences without the ontological baggage.

Organizational aesthetics, both as a body of theory and a method of inquiry, is a rapidly expanding area of the organizational sciences. The Aesthetics of Organization accessibly draws key contributions delineating the emerging parameters of the field.

Methodological problems associated with investigations of the aesthetic are also highlighted so the reader can identify and understand the importance of recent ideas on vision, (...) perspective and periphery for learning in organizations. Through the contributions of leading international theorists, organizational aesthetics is defined in greater historical and theoretical depth, with a broad conceptual and practical range which academics will find invaluable.

A common argument against explanatory reductionism is that higher‐level explanations are sometimes or always preferable because they are more general than reductive explanations. Here I challenge two basic assumptions that are needed for that argument to succeed. It cannot be assumed that higher‐level explanations are more general than their lower‐level alternatives or that higher‐level explanations are general in the right way to be explanatory. I suggest a novel form of pluralism regarding levels of explanation, according to which explanations at (...) different levels are preferable in different circumstances because they offer different types of generality, which are appropriate in different circumstances of explanation. *Received July 2009; revised September 2009. †To contact the author, please write to: Department of Philosophy, Oklahoma State University, 246 Murray Hall, Stillwater, OK 74078; e‐mail: angela.potochnik@okstate.edu.

Research on the normative aspect of leadership is still a relatively new enterprise within the mainstream of leadership studies. In the past, most academic inquiry into leadership was grounded in a social scientific paradigm that largely ignored the ethical substance of leadership. However, perhaps because of a number of public and infamous cases of failure in business leadership, in recent years there has been renewed interest in the ethical side of leadership in business. This paper argues that ethical issues of (...) leadership actually arise at number of different levels, and that it is important to distinguish between various diverse kinds of ethical issues that arise in the study of leadership. The three levels identified are the level of the individual morality of leaders, the level of the means of their leadership, and the level of the leadership mission itself. We argue that only by fully understanding all of the different levels of ethical analysis pertinent to business leadership, and the distinctive kind of issues that arise at each level, can we fully integrate normative studies of leadership into the field of leadership studies. As such, this paper offers a model that incorporates three different levels of ethical analysis that can be used to study normative issues in leadership studies. Such a model can be used to better understand and integrate ethical issues into research, teaching, and training in leadership. (shrink)
The dominant assumptions -- throughout contemporary philosophy, psychology, cognitive science, and artificial intelligence -- about the ontology underlying intentionality, and its core of representationality, is that of encodings -- some sort of informational or correspondence or covariation relationship between the represented and its representation that constitutes that representational relationship. There are many disagreements concerning details and implementations, and even some suggestions about claimed alternative ontologies, such as connectionism (though none that escape what I argue is the fundamental flaw in these (...) dominant approaches). One assumption that seems to be held by all, however, usually without explication or defense, is that there is _one_ singular underlying ontology to representationality. In this paper, I argue that there are in fact quite a number of ontologies that manifest representationality -- levels of representationality -- and that _none_ of them are the standard "manipulations of encoded symbols" ontology, nor any other variation on the informational approach to representation. Collectively, these multiple representational ontologies constitute a framework for cognition, whether natural or artificial. (shrink)
This paper distinguishes and critiques several forms of pluralism about the levels of selection, and introduces a novel way of thinking about the biological properties and processes typically conceptualized in terms of distinct levels. In particular, "levels" should be thought of as being entwined or fused. Since the pluralism discussed is held by divergent theorists, the argument has implications for many positions in the debate over the units of selection. And since the key points on which the (...) paper turns apply beyond this specific issue, the paper may prove of general interest in thinking about the metaphysics of science. (shrink)
Victor and Cullen (1988) identified several dimensions of ethical climate that exist in organizations and organizational subunits. We tested the relationship between these dimensions of ethical climate and ethical behavior at different levels of analysis. Using Within and Between Analysis (WABA) (cf.

In this paper Wimsatt's analysis of units of selection is taken as defining the units of selection question. A definition of levels of selection is offered and it is shown that the levels of selection question is quite different from the units of selection question. Some of the relations between units and levels are briefly explored. It is argued that the levels of selection question is the question relevant to explanatory concerns, and it is suggested that (...) it is the question relevant to ontological concerns. (shrink)
Marr’s celebrated contribution to cognitive science (Marr 1982, chap. 1) was the introduction of (at least) three levels of description/explanation. However, most contemporary research has relegated the distinction between levels to a rather dispensable remark. Ignoring such an important contribution comes at a price, or so we shall argue. In the present paper, first we review Marr’s main points and motivations regarding levels of explanation. Second, we examine two cases in which the distinction between levels has (...) been neglected when considering the structure of mental representations: Cummins et al.’s distinction between structural representation and encodings (Cummins in Journal of Philosophy, 93(12):591–614, 1996; Cummins et al. in Journal of Philosophical Research, 30:405–408, 2001) and Fodor’s account of iconic representation (Fodor 2008). These two cases illustrate the kind of problems in which researchers can find themselves if they overlook distinctions between levels and how easily these problems can be solved when levels are carefully examined. The analysis of these cases allows us to conclude that researchers in the cognitive sciences are well advised to avoid risks of confusion by respecting Marr’s old lesson. (shrink)
Well-known concepts in Organization Behavior are viewed in this paper through a Taoist lens, in particular through the perspective enshrined in the famous yin–yang symbol. Since Tao purports to be a fundamental Law of Nature, it should be possible to find Taoist principles operating within, or at least behind, concepts and theories presented in the field of Organization Behavior as having some degree of truth value. Concepts from personality theory, learning, motivation, leadership, and organization culture are found (...) indeed to accord with the Tao. The review reveals aspects of OB concepts not usually discussed, and suggests a fresh approach for theory evaluation and development. A general principle of yin–yang balance as an essential dynamic for performance and harmony in a wide variety of contexts is suggested. Implications for further research are indicated. (shrink)

I introduce a case study from organization studies to argue that social epistemologists’ recommendation to cultivate diversity and dissent in science is unlikely to be welcomed in the social sciences unless it is coupled with another epistemic ideal: the norm of epistemic responsibility.

This article gives a practice-based and theoretical overview of the transformation from a traditional hierarchical organization in the care and cure sector towards a so-called Community-driven organization providing human happiness to 6000 elderly people. The actual case study is intertwined with conceptual information for better understanding of the innovative transition which took place at Humanitas. The case description includes its initial situation, its new core values, mission and objectives and shows the sequence of emerging policies and interventions that (...) resulted in a stakeholder oriented business model for the care sector. The selected concepts are Graves'' Emerging Cyclical Level of Existence Theory (or Spiral Dynamics), Ken Wilber''s Four Quadrant Model, Roberts Simons'' Four Levers of Control and various elements from the European Corporate Sustainability Framework sponsored by the European Commission. The conclusion marks the match between theory and practice in transforming Humanitas Rotterdam into providing cure, care, housing and well-being to elderly people. (shrink)
When do children become aware of themselves as differentiated and unique entity in the world? When and how do they become self-aware? Based on some recent empirical evidence, 5 levels of self-awareness are presented and discussed as they chronologically unfold from the moment of birth to approximately 4-5 years of age. A natural history of children's developing self-awareness is proposed as well as a model of adult self-awareness that is informed by the dynamic of early development. Adult self-awareness is (...) viewed as the dynamic flux between basic levels of consciousness that develop chronologically early in life. (shrink)
Quite a few recent models are rapidly introducing new concepts describing different levels of consciousness. This situation is getting confusing because some theorists formulate their models without making reference to existing views, redundantly adding complexity to an already difficult problem. In this paper, I present and compare nine neurocognitive models to highlight points of convergence and divergence. Two aspects of consciousness seem especially important: perception of self in time and complexity of self-representations. To this I add frequency of self-focus, (...) amount of self-related information, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extended, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in relation to mirror self-recognition and language.

Starting from Dennett's distinction between personal and sub-personal levels of description, I consider the relationships amongst three levels: the personal level, the level of information-processing mechanisms, and the level of neurobiology. I defend a conception of the relationship between the personal level and the sub-personal level of information-processing mechanisms as interaction without reduction . Even given a nonreductionist conception of persons, philosophical theorizing sometimes supports downward inferences from the personal to the sub-personal level. An example of a downward (...) inference is provided and an objection is considered. (shrink)
We examine some assumptions about the nature of ‘levels of reality’ in the light of examples drawn from physics. Three central assumptions of the standard view of such levels (for instance, Oppenheim and Putnam 1958) are (i) that levels are populated by entities of varying complexity, (ii) that there is a unique hierarchy of levels, ranging from the very small to the very large, and (iii) that the inhabitants of adjacent levels are related by the (...) parthood relation. Using examples from physics, we argue that it is more natural to view the inhabitants of levels as the behaviors of entities, rather than entities themselves. This suggests an account of reduction between levels, according to which one behavior reduces to another if the two are related by an appropriate limit relation. By considering cases where such inter-level reduction fails, we show that the hierarchy of behaviors differs in several respects from the standard hierarchy of entities. In particular, while on the standard view, lower-level entities are ‘micro’ parts of higher-level entities, on our view, a system’s macro-level behavior can be seen as a (‘non-spatial’) part of its micro-level behavior. We argue that this second hierarchy is not really in conflict with the standard view and that it better suits examples of explanation in science. (shrink)
Until recently, the notions of function and multiple realization were supposed to save the autonomy of psychological explanations. Furthermore, the concept of supervenience presumably allows both dependence of mind on brain and non-reducibility of mind to brain, reconciling materialism with an independent explanatory role for mental and functional concepts and explanations. Eliminativism is often seen as the main or only alternative to such autonomy. It gladly accepts abandoning or thoroughly reconstructing the psychological level, and considers reduction if successful as equivalent (...) with elimination. In comparison with the philosophy of mind, the philosophy of biology has developed more subtle and complex ideas about functions, laws, and reductive explanation than the stark dichotomy of autonomy or elimination. It has been argued that biology is a patchwork of local laws, each with different explanatory interests and more or less limited scope. This points to a pluralistic, domain-specific and multi-level view of explanations in biology. Explanatory pluralism has been proposed as an alternative to eliminativism on the one hand and methodological dualism on the other hand. It holds that theories at different levels of description, like psychology and neuroscience, can co-evolve, and mutually influence each other, without the higher-level theory being replaced by, or reduced to, the lower-level one. Such ideas seem to tally with the pluralistic character of biological explanation. In biological psychology, explanatory pluralism would lead us to expect many local and non-reductive interactions between biological, neurophysiological, psychological and evolutionary explanations of mind and behavior. This idea is illustrated by an example from behavioral genetics, where genetics, physiology and psychology constitute distinct but interrelated levels of explanation. Accounting for such a complex patchwork of related explanations seems to require a more sophisticated and precise way of looking at levels than the existing ideas on (reductive and non-reductive) explanation in the philosophy of mind.

My main thesis is this paper is that, although Dretske's distinction between simple perception and cognitive perception constitutes an important milestone in contemporary theorizing on perception, it remains too coarse to account for a number of phenomena that do not seem to fall squarely on either side of the divide. I argue that what is needed in order to give a more accurate account of perceptual phenomena is not a twofold distinction of the kind advocated by Dretske but a threefold (...) distinction allowing for an intermediate level of perceptual content that is structured and yet non-conceptual. In the first section, I discuss Dretske's distinction between sensory perception and cognitive perception as well as a number of attendant notions. In section 2, two sets of phenomena that seem neither to constitute instances of sensory perception nor instances of cognitive perception as defined by Dretske are presented. I argue that they are evidence in favor of the existence of an intermediate level of perception. In section 3, I defend the view that this intermediate level of content is a level of structured non-conceptual perceptual content and I attempt to provide criteria for distinguishing among the three levels of content.

I discuss two subjects in Samir Okasha’s excellent book, Evolution and the Levels of Selection. In consonance with Okasha’s critique of the conventionalist view of the units of selection problem, I argue that conventionalists have not attended to what realists mean by group, individual, and genic selection. In connection with Okasha’s discussion of the Price equation and contextual analysis, I discuss whether the existence of these two quantitative frameworks is a challenge to realism.
The discussion of the relation of levels of reality to categories is important because categories have often been interpreted as constituting levels of reality.

Does natural selection act primarily on individual organisms, on groups, on genes, or on whole species?

Two main theories about metacognition are reviewed, each of which claims to provide a better explanation of this phenomenon, while discrediting the other theory as inappropriate. The paper claims that in order to do justice to the complex phenomenon of metacognition, we must distinguish two levels of this capacity—each having a different structure, a different content and a different function within the cognitive architecture. It will be shown that each of the reviewed theories has been trying to explain only (...) one of the two levels and that, consequently, the conflict between them can be dissolved. The paper characterizes the high-level as a rationalizing level where the subject uses concepts and theories to interpret her own behavior and the low-level as a controlling level where the subject exploits epistemic feelings to adjust her cognitive activities. Finally, the paper explores three kinds of interaction between the levels. (shrink)
In Delusions and Other Irrational Beliefs , Lisa Bortolotti argues that the irrationality of delusions is no barrier to their being classified as beliefs. This comment asks how Bortolotti’s position may be affected if we accept that there are two distinct types of belief, belonging to different levels of mentality and subject to different ascriptive constraints. It addresses some worries Bortolotti has expressed about the proposed two-level framework and outlines some questions that arise for her if the framework is (...) adopted. It also suggests that, rather than being beliefs that fail to meet the relevant standards of rationality, delusions may be non-doxastic acceptances that were never meant to meet them. (shrink)

To this I add frequency (...) of self-focus, amount of self-related informa- tion, and accuracy of self-knowledge. Overall, I conclude that many novel concepts (e.g., reflective, primary, core, extend- ed, recursive, and minimal consciousness) are useful in helping us distinguish between delicate variations in consciousness and in clarifying theoretical issues that have been intensely debated in the scientific literature—e.g., consciousness in rela- tion to mirror self-recognition and language.

The article first addresses the importance of cognitive modeling, in terms of its value to cognitive science (as well as other social and behavioral sciences). In particular, it emphasizes the use of cognitive architectures in this undertaking. Based on this approach, the article addresses, in detail, the idea of a multi-level approach that ranges from social to neural levels. In physical sciences, a rigorous set of theories is a hierarchy of descriptions/explanations, in which causal relationships among entities at a (...) high level can be reduced to causal relationships among simpler entities at a more detailed level. We argue that a similar hierarchy makes possible an equally productive approach toward cognitive modeling. The levels of models that we conceive in relation to cognition include, at the highest level, sociological/anthropological models of collective human behavior, behavioral models of individual performance, cognitive models involving detailed mechanisms, representations, and processes, as well as biological/physiological models of neural circuits, brain regions, and other detailed biological processes.

Levels of reality reflect one kind of complexity, which can be modeled using a specification hierarchy. Levels emerged during the Big Bang, as physical degrees of freedom became increasingly fixed as the expanding universe developed, and new degrees of freedom associated with higher levels opened up locally, requiring new descriptive semantics. History became embodied in higher level entities, which are increasingly individuated, aggregate patterns of lower level entities. Development is an epigenetic trajectory from vaguer to more definite (...) and individuated embodiment, punctuated by the emergence of new integrative levels. It is constrained by being subsumed by lower levels (e.g., physical dynamics) and may be guided by structural attractors as well as by internally stored information (e.g., genes) in the higher levels. I conjecture, on a thermodynamic basis, that the number of levels that become manifest in an expanding universe depends upon its rate of expansion. (shrink)
The debate about the levels of selection has been one of the most controversial both in evolutionary biology and in philosophy of science. Okasha’s book makes the sort of contribution that simply will not be able to be ignored by anyone interested in this field for many years to come. However, my interest here is in highlighting some examples of how Okasha goes about discussing his material to suggest that his book is part of an increasingly interesting trend that (...) sees scientists and philosophers coming together to build a broadened concept of “theory” through a combination of standard mathematical treatments and conceptual analyses. Given the often contentious history of the relationship between philosophy and science, such trend cannot but be welcome. (shrink)
The levels of selection problem was central to Maynard Smith’s work throughout his career. This paper traces Maynard Smith’s views on the levels of selection, from his objections to group selection in the 1960s to his concern with the major evolutionary transitions in the 1990s. The relations between Maynard Smith’s position and those of Hamilton and G.C. Williams are explored, as is Maynard Smith’s dislike of the Price equation approach to multi-level selection. Maynard Smith’s account of the ‘core (...) Darwinian principles’ is discussed, as is his debate with Sober and Wilson (1998) over the status of trait-group models, and his attitude to the currently fashionable concept of pluralism about the levels of selection.

In this paper, we put forward an interdisciplinary framework describing different levels of self-representations, namely non-conceptual, conceptual and propositional self-representations. We argue that these different levels of self-representation are differently affected by cultural upbringing: while propositional self-representations rely on “theoretical” concepts and are thus strongly influenced by cultural upbringing, non-conceptual self-representations are uniform across cultures and thus universal. This differentiation offers a theoretical specification of the distinction between an independent and interdependent self-construal put forward in cross-cultural psychology. Hence, (...) this does not only allow for a deeper understanding of different self-conceptions, but also for a formulation of new hypotheses regarding the cultural influence on self-representations. As one example, we will highlight the role of the proposed levels of self-representation for emotional experience and formulate some major implications of our interdisciplinary framework for future empirical research.

This study examines the ethical values of respondents by level in the organizational hierarchy of a single firm. It also explores the possible impacts of gender, education and years of experience on respondents' values as well as their perceptions of how the organization and professional associations influence their personal values. Results showed that, although there were differences in individuals' ethical values by hierarchical level, significantly more differences were observed by the length of tenure with the organization. While respondents, (...) as a whole, were rather ambivalent in their perception of the organization's and professional associations' influence on their values, sales/service persons frequently felt pressured to modify their values in order to achieve company goals.

This paper discusses the relation between cognitive and implementational levels of analysis. Chalmers (1990, 1993) argues that a connectionist implementation of a classical cognitive architecture possesses a compositional semantics, and therefore undercuts Fodor and Pylyshyn's (1988) argument that connectionist networks cannot possess a compositional semantics. I argue that Chalmers argument misconstrues the relation between cognitive and implementational levels of analysis. This paper clarifies the distinction, and shows that while Fodor and Pylyshyn's argument survives Chalmers' critique, it cannot be (...) used to establish the irrelevance of neurophysiological implementation to cognitive modeling; some aspects of Chater and Oaksford's (1990) response to Fodor and Pylyshyn, though not all, are therefore cogent.

This paper elaborates on the link between different types and degrees of experience that can be gone through within a form of life or collectivity—the so-called levels of immersion—and the development of distinct types of tacit knowledge and expertise. The framework is then probed empirically and theoretically. In the first case, its ‘predictions’ are compared with the accounts of novices who have gone through different ‘learning opportunities’ during a pre-operational training programme for running a huge nickel industrial plant in (...) Brazil. These are also analysed vis-à-vis the experience of an expert who has designed and experienced the outcomes of two pre-operational training sessions in the nickel industry before developing and managing the one discussed here. Theoretically, the framework is used to pinpoint exactly what interactional experts who have developed their expertise through linguistic socialisation alone are able to do as well as to analyse the case of technical connoisseurs. The results indicate that the proposed framework is useful. It supports the design and improvement of training programmes for the development of tacit knowledge while at the same time bringing about a refined analysis of claims concerning the abilities of types of experts and expertise.

The thesis is defended that the theories of causation, time and space, and levels of reality are mutually interrelated in such a way that the difficulties internal to theories of causation and to theories of space and time can be understood better, and perhaps dealt with, in the categorial context furnished by the theory of the levels of reality. The structural condition for this development to be possible is that the first two theories be opportunely generalized.
Some controversies in cognitive science, such as arguments about whether classical or distributed connectionist architectures best model the human cognitive system, reenact long-standing debates in the philosophy of science. For millennia philosophers have pondered whether mentality can submit to scientific explanation generally and to physical explanation particularly. Recently, positive answers have gained popularity. The question remains, though, as to the analytical level at which mentality is best explained. Is there a level of analysis that is peculiarly appropriate for the explanation (...) of either consciousness or mental contents? Are human consciousness, cognition, and conduct best understood in terms of talk about neurons and networks or schemas and scripts or intentions and inferences? If our best accounts make no appeal to our hopes or beliefs or desires, how do we square those views with our conception of ourselves as rational beings? Moreover, can models of physical processes explain our mental lives? Does mentality require a special level of rational or cognitive explanation or is it best understood in terms of overall brain functioning or neuronal or molecular or even quantum activities--or any of a dozen levels of physical explanation in between? Also, regardless of how they compare with explanations cast at physical levels, what is the status of psychological explanations that appeal fundamentally to mental contents? As a means for beginning to address such questions, proposals about cognitive architecture concern which kind of explanation best characterizes primitive psychological activities. Although, technically, approaches to modeling those activities are unlimited, two 1 strategies have enjoyed most of the attention. The prominence of the classical account and the distributed connectionist (or parallel distributed processing (PDP)) account, notwithstanding, nothing bars the development of additional proposals. Classicism employs rules that apply to symbolic representations to explain cognitive processing.. (shrink)

Notwithstanding many similarities between Thelen et al.'s and Piaget's accounts of the A-not-B error, we argue that, in contrast to Piaget, they do not explicitly address the issue of objectivity. We suggest that this omission is partly due to the fact that Thelen et al. and Piaget's accounts are pitched at different levels of explanation.
Conceptual space is proposed as an intermediate representation level between the psychological and the neurobiological levels of descriptions of appraisal and emotions. The main advantage of the proposed intermediate representation is that the appraisal and emotions dynamics are described by using the terms of geometry.
It seems that I often say things that might mistakenly be thought to identify me as an adherent of the radical neuron doctrine. I take the opportunity to explain my position more clearly and argue that many apparent conflations of the radical and trivial neuron doctrines are merely the result of misunderstanding what is meant when neuroscientists talk about the relations between different levels of description. It follows that there may be considerably fewer followers of the radical doctrine than (...) Gold & Stoljar suggest. (shrink)
The notion of levels has been widely used in discussions of cognitive science, especially in discussions of the relation of connectionism to symbolic modeling of cognition. I argue that many of the notions of levels employed are problematic for this purpose, and develop an alternative notion grounded in the framework of mechanistic explanation. By considering the source of the analogies underlying both symbolic modeling and connectionist modeling, I argue that neither is likely to provide an adequate analysis of (...) processes at the level at which cognitive theories attempt to function: One is drawn from too low a level, the other from too high a level. If there is a distinctly cognitive level, then we still need to determine what are the basic organizational principles at that level. (shrink)
I begin by tracing some of the confusions regarding levels and reduction to a failure to distinguish two different principles according to which theories can be viewed as hierarchically arranged — epistemic authority and ontological constitution. I then argue that the notion of levels relevant to the debate between symbolic and connectionist paradigms of mental activity answers to neither of these models, but is rather correlative to the hierarchy of functional decompositions of cognitive tasks characteristic of homuncular functionalism. (...) Finally, I suggest that the incommensurability of the intentional and extensional vocabularies constitutes a strongprima facie reason to conclude that there is little likelihood of filling in the story of Bechtel''s missing level in such a way as to bridge the gap between such homuncular functionalism and his own model of mechanistic explanation.

This paper discusses the content of agency awareness. It contrast three elements in content: what the goal is, how it is to be reached, and who is having the goal/performing the action ? Marc Jeannerod's claim that goal representations are self-other neutral is discussed. If goal representations are essentially sharable, then we do not understand other people by projecting a piece of internal knowledge on to them, as often assumed. The problem which our brain has to solve is the converse (...) problem : determining who the agent is, once a goal is identified. This view has interesting consequences on the theory of mentalization. One can plausibly speculate that observing action, with an additional simulatory component for action memory, form major building blocks in understanding other minds. Metarepresenting, in this perspective, would depend on additional executive capacities for maintaining distinct the inferences from diverse simulated contexts of action. (shrink)
Individual and group selection are usually conceived as opposed evolutionary processes. Though cases of synergy are occasionally recognized, the evolutionary importance of synergy is largely ignored. However, synergy is the plausible explanation for the evolution of collectives as higher level individuals i.e., collectives acting as adaptive units, e.g., genomes and colonies of social insects. It rests on the suppression of the predictable tendency of evolutionary units to benefit at the expense of other units or of the wholes they contribute to (...) build. It plausibly explains human cooperation and morality: the molding of human groups into adaptive units. (shrink)
Activity anorexia illustrates selection of behavior at the biological, behavioral, and neural levels. Based on evolutionary history, food depletion increases the reinforcement value of physical activity that, in turn, decreases the reinforcement effectiveness of eating – resulting in activity anorexia. Neural opiates participate in the selection of physical activity during periods of food depletion.
The debate of nativisim versus empiricism is over the relative importance of evolutionary versus ontogenetic mechanisms. This is mostly seen today as a false dichotomy. The synthesis of these positions provides a modern viewpoint of grounded category formation. This combined view places equal importance on feedback between these levels in guiding development, and is more appropriately compared to culturalist positions.
In recent years Jaegwon Kim has offered an argument – the ‘supervenience argument’ – to show that supervenient mental properties, construed as second- order properties distinct from their first-order realizers, do not have causal powers of their own. In response, several philosophers have argued that if Kim’s argument is sound, it generalizes in such a way as to condemn to causal impotency all properties above the level of basic physics. This paper discusses Kim’s supervenience argument in the context of his (...) reply to this so-called ‘generalization argument’. In particular, the paper focuses on the level/order distinction, to which Kim appeals in his reply to the generalization argument, and on the relation between this distinction and two varieties of functionalism, ‘realizer’ vs. ‘role’ functionalism. The author argues that a proper analysis of the notions of levels and orders undermines Kim’s response to the generalization argument, and suggests that Kim’s reductionist strategy for vindicating the causal powers of mental properties is better served if mental properties are construed as first-order properties, as realizer-functionalism recommends.

This article examines an account of the listener's musical understanding put forward by Stephen Davies. I begin by discussing Davies's "expressibility requirement", according to which a musical listener should be able to express his understanding in sentences that are truth-apt. This is followed by a reconstruction of Davies's argument for the idea that high levels of musical understanding can be attained without possessing music-theoretical concepts. Such a conclusion is seen to follow from his belief that although musical understandings may (...) be evaluatively compared in terms of the concepts of music theory, the listeners themselves can always fulfil the expressibility requirement by employing simple "folk-musicological" terminology. I will attempt to show that this premise is questionable in the light of some central cases of music-structural understanding. I conclude by examining the relationship between Davies's expressibility requirement and the claim that musical understandings are evaluatively commensurable. (shrink)
Treating consciousness as awareness or attention greatly underestimates it, ignoring the temporary levels of organization associated with higher intellectual function (syntax, planning, logic, music). The tasks that require consciousness tend to be the ones that demand a lot of resources. Routine tasks can be handled on the back burner but dealing with ambiguity, groping around offline, generating creative choices, and performing precision movements may temporarily require substantial allocations of neocortex. Here I will attempt to clarify the appropriate (...) class='Hi'>levels of explanation (ranging from quantum aspects to association cortex dynamics) and then propose a specific mechanism (consciousness as the current winner of Darwinian copying competitions in cerebral cortex) that seems capable of encompassing the higher intellectual function aspects of consciousness as well as some of the attentional aspects. It includes features such as a coding space appropriate for analogies and a supervisory Darwinian process that can bias the operation of other Darwinian processes. (shrink)
Caenorhabditis elegans (C. elegans) is a tiny worm that has become the focus of a large number of worldwide research projects examining its genetics, development, neuroscience, and behavior. Recently several groups of investigators have begun to tie together the behavior of the organism and the underlying genes, neural circuits, and molecular processes implemented in those circuits. Behavior is quintessentially organismal--it is the organism as a whole that moves and mates--but the explanations are devised at the molecular and neurocircuit levels, (...) and tested in populations using protocols that span many levels of aggregation. Following a brief review of the main relevant features of C. elegans, I describe some of these circuits, and then discuss two contrasting approaches in behavioral genetics and neural network analysis of the worm. Finally, I outline the rudiments of a "field and focus" explanation model using the two contrasting approaches. (shrink)
This paper describes a set of ideal type organizations in a developmental sequence. As these descriptions are based on Spiral Dynamics (or Emerging Cyclical Levels of Existence Theory – ECLET), the types are labeled as Order, Success, Community and Synergy. Per type the author elaborated on the underlying value system and relating institutional structures, such as leadership role, governance and measurement format. As a summary, a Transition Matrix is presented which indicate the paradigm shifts per discipline/department, as manifested in (...) the subsequent ideal type organizations. As Order and Success generally describe the majority of corporations in Western Economies, the latter two types introduce new approaches to more innovative – and more sustainable/responsible – ways to doing business. Based on Community Values, the author introduces a new measurement format which is the foundation for a systemic and coherent set of management tools to be used in a stakeholder approach. These tools relate to the strategic, tactical and operational tasks of management and have been developed by researchers of the European Corporate Sustainability Framework (ECSF) consortium. The set includes two tools which are generic: the Strategic Sustainability Scan (Strategy) and the Sustainability Matrix, which is a self-assessment tool (tactics). Three operational tools are context and industry specific: These are the Community related Responsive Business Scorecard (RBS) and Benchmark Format for measuring and monitoring sustainability performance and a methodology – a Management Information System – to generate information on people, planet and profit in order to provide data for the set of key performance indicators.

Here we discuss the challenge posed by self-organization to the Darwinian conception of evolution. As we point out, natural selection can only be the major creative agency in evolution if all or most of the adaptive complexity manifest in living organisms is built up over many generations by the cumulative selection of naturally occurring small, random mutations or variants, i.e., additive, incremental steps over an extended period of time. Biological self-organization—witnessed classically in the folding of a protein, or (...) in the formation of the cell membrane—is a fundamentally different means of generating complexity. We agree that self-organizing systems may be fine-tuned by selection and that self-organization may be therefore considered a complementary mechanism to natural selection as a causal agency in the evolution of life. But we argue that if self-organization proves to be a common mechanism for the generation of adaptive order from the molecular to the organismic level, then this will greatly undermine the Darwinian claim that natural selection is the major creative agency in evolution. We also point out that although complex self-organizing systems are easy to create in the electronic realm of cellular automata, to date translating in silico simulations into real material structures that self-organize into complex forms from local interactions between their constituents has not proved easy. This suggests that self-organizing systems analogous to those utilized by biological systems are at least rare and may indeed represent, as pre-Darwinists believed, a unique ascending hierarchy of natural forms. Such a unique adaptive hierarchy would pose another major challenge to the current Darwinian view of evolution, as it would mean the basic forms of life are necessary features of the order of nature and that the major pathways of evolution are determined by physical law, or more specifically by the self-organizing properties of biomatter, rather than natural selection.

Abstract Microtubules, major elements of the cell skeleton are, most of the time, well organized in vivo, but they can also show self-organizing behaviors in time and/or space in purified solutions in vitro. Theoretical studies and models based on the concepts of collective dynamics in complex systems, reaction–diffusion processes and emergent phenomena were proposed to explain some of these behaviors. In the particular case of microtubule spatial self-organization, it has been advanced that microtubules could behave like ants, self-organizing by (...) ‘talking to each other’ by way of hypothetic (because never observed) concentrated chemical trails of tubulin that are expected to be released by their disassembling ends. Deterministic models based on this idea yielded indeed like-looking spatio-temporal self-organizing behaviors. Nevertheless the question remains of whether microscopic tubulin trails produced by individual or bundles of several microtubules are intense enough to allow microtubule self-organization at a macroscopic level. In the present work, by simulating the diffusion of tubulin in microtubule solutions at the microscopic scale, we measure the shape and intensity of tubulin trails and discuss about the assumption of microtubule self-organization due to the production of chemical trails by disassembling microtubules. We show that the tubulin trails produced by individual microtubules or small microtubule arrays are very weak and not elongated even at very high reactive rates. Although the variations of concentration due to such trails are not significant compared to natural fluctuations of the concentration of tubuline in the chemical environment, the study shows that heterogeneities of biochemical composition can form due to microtubule disassembly. They could become significant when produced by numerous microtubule ends located in the same place. Their possible formation could play a role in certain conditions of reaction. In particular, it gives a mesoscopic basis to explain the collective dynamics observed in excitable microtubule solutions showing the propagation of concentration waves of microtubules at the millimeter scale, although we doubt that individual microtubules or bundles can behave like molecular ants.

In Chinese philosophy, although the concept of qi has numerous meanings, it is not completely without order or chaotic. Generally speaking, qi has several different levels of meanings, such as in philosophy, physics, physiology, psychology, ethics, and so on.

It is from this point that (...) the meanings of qi in physiology, psychology, ethics as well as aesthetics are derived. This paper analyzes the meanings of qi on five levels and seeks to clarify misunderstandings about qi, such as its alleged pan-vitalistic, conscious and pan-ethical characters. (shrink)
A hypothesis of genome structural evolution is explored. Rapid and cohesive alterations in genome organization are viewed as resulting from the dynamic and constrained interactions of chromosomal subsystem components. A combination of macromolecular boundary conditions and DNA element involvement in far-from-equilibrium reactions is proposed to increase the complexity of genomic subsystems via the channelling of genome turnover; interactions between subsystems create higher-order subsystems expanding the phase space for further genetic evolution. The operation of generic constraints on structuration in genome (...) evolution is suggested by i) universal, homoplasic features of chromosome organization and ii) the metastable nature of genome structures where lower-level flux is constrained by higher-order structures. Phenomena such as genomic shock, bursts of transposable element activity, concerted evolution, etc., are hypothesized to result from constrained systemic responses to endogenous/exogenous, micro/macro perturbations. The constraints operating on genome turnover are expected to increase with chromosomal structural complexity, the number of interacting subsystems, and the degree to which interactions between genomic components are tightly ordered.

The growth activity of an organ (variable y) is defined simultaneously by the instantaneous absolute ratedy/dt and its variationd 2y/dt2. The use of these two descriptors allows a sigmoidal (i.e. continuous and non periodical, as observed for the logistic function) growth curve to be discretized into a series of 5 growth states or phases which are delimited by the following singular values: max, Vmax (=0), max, adult stage. The (V, ) plot, termedgrowth trajectory, visualizes, e.g. in the case of Richards-Nelder's (...) generalized logistics, the unequal duration of these phases and allows the dissymmetry property of the growth function to be characterized precisely.At a more integrated organization level, such anorganic series (e. g. the set of the leaves borne by a same branch), the above concepts allow two kinds of analyses to be carried out: (i) in thekinetic approach, the growth trajectory of the series can characterizes, under certain conditions, the emergence of a new property: theoccurrence of growth activity rhythms which are independent of meristem dormancy processes; (ii) thedemographic approach shows thegrowth structure of the phytomer population (a particular form of age structure) and the associated dimensional structure (plant partition into zones or regions in relation to the growth state of the various phytomers).

Context: Using radical constructivism, society can be considered from the perspective of asking the question, “Who conceives of society?” In Luhmann’s social systems theory, this question itself is considered as a construct of the communication among reflexive agents. Problem: Structuration of expectations by codes operating in interhuman communications positions both communicators and communications in a multi-dimensional space in which their relations can be provided with meaning at the supra-individual level. The codes can be functionally different and symbolically generalized. Method: More (...) than Luhmann, I focus on the hypothetical status of the communication of meaning and the uncertainty involved. Meaning can be communicated because of reflexivity in interhuman communications; meaning cannot be observed. Results: The communication (and reflexive translation) of denotations between semantic domains can generate “horizons of meaning” as reflexive orders that remain structurally coupled to individual minds. This elusive order contains a trade-off between “organization” at interfaces integrating (differently coded) expectations at each moment of time, and the potential of further differentiation among symbolically generalized codes of communication in a “self-organization” over time. Implications: One can model the coding in the communication of meaning as latent variables (eigenvectors) that evolve as an implication of the interacting intentions and expectations. The structure of expectations can be visualized (at each moment) and animated (over time) using semantic maps. The self-organizing horizons of meaning operate in a multidimensional space different from the network topology, and at another pace, since meaning is provided to events from the perspective of hindsight. Constructivist content: This perspective of the radical constructedness of social reality transforms the status of agency and organization in sociological theorizing from a source of change to a resource of communicative competencies and reflexive performativity.

Hayek maintains that models of complexity must consider two closely interrelated factors: the large number of variables and the connections among them. These two conditions, which define complex phenomena, exhibit a different logical dimension. The former (the ?large number of variables?) describes complexity in quantitative (numerical) terms; the latter provides a view of complex phenomena in logical-relational terms, and it is evoked to explain the emergent properties of the whole. Despite the close relation between these concepts, the first notion essentially (...) prevails over the latter, delineating a distinctive configuration of the theory. This perspective also emerges when Hayek defines ?dispersed? and ?inarticulate? knowledge, and introduces the concept of the ?explanations of the principles?. Finally, the notion of level of analysis is discussed in order to interpret Hayek's two concepts which define complexity. (shrink)
This study examines the ethical climate and ethical practices of successful managers (n=206 managers) of a large non-profit organization. The influence of different dimensions of ethical climate on perceived ethical practices of successful managers were also investigated.

Compared to previous research, managers in our sample were less optimistic about the relationship between success and ethical behavior. Those who believed that their organization had a caring climate (...) perceived a strong positive link between success and ethical behavior. Those who believed that their organization had an instrumental climate perceived a strong negative link between success and ethical behavior. (shrink)
Possibly the most fundamental scientific problem is the origin of time and causality. The inherent difficulty is that all scientific theories of origins and evolution consider the existence of time and causality as given. We tackle this problem by starting from the concept of self-organization, which is seen as the spontaneous emergence of order out of primordial chaos. Self-organization can be explained by the selective retention of invariant or consistent variations, implying a breaking of the initial symmetry exhibited (...) by randomness. In the case of time, we start from a random graph connecting primitive “events”. Selection on the basis of consistency eliminates cyclic parts of the graph, so that transitive closure can transform it into a partial order relation of precedence. Causality is assumed to be carried by causal “agents” which undergo a more traditional variation and selection, giving rise to causal laws that are partly contingent, partly necessary. (shrink)
Donald Campbell has long advocated a naturalist epistemology based on a general selection theory, with the scope of knowledge restricted to vicarious adaptive processes. But being a vicariant is problematic because it involves an unexplained epistemic relation. We argue that this relation is to be explicated organizationally in terms of the regulation of behavior and internal state by the vicariant, but that Campbell's selectionist approach can give no satisfactory account of it because it is opaque to organization. We show (...) how organizational constraints and capacities are crucial to understanding both evolution and cognition and conclude with a proposal for an enriched, generalized model of evolutionary epistemology that places high-order regulatory organization at the center.

This paper suggests that an organization's structure may perform a significant role in the decision to report versus not report an observed wrongdoing.

In this paper, we compare the mechanisms of protein synthesis and natural selection. We identify three core elements of mechanistic explanation: functional individuation, hierarchical nestedness or decomposition, and organization. These are now well understood elements of mechanistic explanation in fields such as protein synthesis, and widely accepted in the mechanisms literature. But Skipper and Millstein have argued (2005) that natural selection is neither decomposable nor organized. This would mean that much of the current mechanisms literature does not apply to (...) the mechanism of natural selection. (shrink)
Non-profit (NP) organizations present complex challenges in managing stakeholder relationships, particularly during times of environmental change. This places a premium on knowing which stakeholders really matter if an effective relationship marketing strategy is to be developed. This article presents the successful application of a model, which combines Mitchell’s theory of stakeholder saliency and Coviello’s framework of contemporary marketing practices in a leading NP organization in the U.K. A cooperative enquiry approach is used to explore stakeholder relationships, dominant marketing practices, (...) and to surface differing perceptions about the organization’s marketing strategy. Resolving these differences sets the scene for developing choices in marketing strategy for the future. (shrink)

This paper documents the development and implementation of an ethically valid code of ethics in a newly formed national professional organization. It describes the experience and challenges faced by the National Association of Senior Move Managers (NASMM) and its leaders as they worked to establish ethics as an organizing framework early in its evolution. Designed by the investigators and supported by the NASMM Board, the process took place over a 2 year period and more than 130 people participated. It (...) provides a model for code development that is both practical and grounded in theory. Although the content of a code of ethics (the “product”) provides guidance to organizational members in the conduct of everyday business, especially when they face ethically challenging situations, how the code is developed (the “process”) influences its ethical validity. Few published cases document an organization’s experience developing a code, and this is the first case, to our knowledge, that provides a first-hand longitudinal account of an effective code development process.

This article argues that the introduction of value based management in a decentralized, hierarchical, and rule-based organization will add to existing informal and formal systems instead of replacing them. Consequently, employees' perception of and willingness to embrace and operationalize centrally imposed values were assumed to be dependent upon existing emotional, social, and formal processes and structures. Hierarchical regression analysis on data from a maritime company (N = 408) gathered in Norway in 2004 – which claims to be a learning (...) and value based company – showed that affective commitment and group coherence correlated positively with perception of values among employees. Formalization was positively but insignificantly correlated, whereas loyalty toward immediate superiors was significantly negatively correlated with perception of values. (shrink)
The reductionistic vision of evolutionary theory, "the gene's eye view of evolution" is the dominant view among evolutionary biologists today. On this view, the gene is the only unit with sufficient stability to act as a unit of selection, with individuals and groups being more ephemeral units of function, but not of selection. This view is argued to be incorrect, on several grounds. The empirical and theoretical bases for the existence of higher-level units of selection are explored, and alternative analyses (...) discussed critically. The success of a multi-level selection theory demands the recognition and development of a multi-level genetics. The way to accomplish this is suggested. The genotype/phenotype distinction also requires further analysis to see how it applies at higher levels of organization. This analysis provides a way of defining genotype and phenotype for cultural evolution, and a treatment of the innate-acquired distinction which are both generalizeable to analyze problems of the nature and focus of scientific change.

The existing literature on the relationship between organizational commitment and ethical decision making suggests that ethical decision makers with higher organizational commitment are less likely to engage in ethically questionable behaviors. The ethical behaviors previously studied in an organizational commitment context have been organization-harm issues in which the organization was harmed and the individual benefited (e.g., overstating an expense report). There is another class of ethical issues in an organizational context, however. These other issues, termed organization-gain issues, (...) focus on the organization obtaining a benefit while outsiders, such as investors, are harmed (e.g., overstating reported revenue). We explore whether individuals with higher organizational commitment are more or less likely to engage in questionable behaviors that benefit the organization. Results of our study indicate that individuals with higher organizational commitment are less likely to engage in ethically questionable behaviors, regardless of whether the behaviors are organization-harm or organizational-gain issues.

Scholars have suggested that the tendency for an individual to perceive him- or herself as more ethical than others might influence the individual''s perceptions of his or her organization''s ethics. The purpose of this study is to consider if and/or when such a relationship exists. A thorough consideration of the nature of perceptions of relative ethicality suggests that a positive self-bias would negatively influence perceptions of organizational ethicality. The results of an empirical study involving working managers and employees of (...) a hospital support that argument. Furthermore, the results indicate that organizational identification, perceived organizational cohesion, and an individual''s insulation also influence individual perceptions of relative organizational ethicality. The findings illuminate this particular phenomenon and further our understanding of the relationship between the individual and the organization, more generally. (shrink)
The purpose of this study was to determine if there is a relationship between the ethical climate of the organization and the development of person-organization fit. The relationship between an individual's stage of moral development and his/her perceived ethical work environment was examined using a sample of 86 working students. Results indicate that a match between individual preferences and present position proved most satisfying. Subjects expressing a match between their preferences for an ethical work climate and their present (...) ethical work climate indicated that they were less likely to leave their positions. (shrink)
When developing phylogenetic systematics, the entomologist Willi Hennig adopted elements from Nicolai Hartmann’s ontology. In this historical essay I take on the task of documenting this adoption. I argue that in order to build a metaphysical foundation for phylogenetic systematics, Hennig adopted from Hartmann four main metaphysical theses. These are (1) that what is real is what is temporal; (2) that the criterion of individuality is to have duration; (3) that species are supra-individuals; and (4) that there are levels (...) of reality, each of which may be subject to different kinds of law. Reliance on Hartmann’s metaphysics allowed Hennig to ground some of the main theoretical principles of phylogenetic systematics, namely that the biological categories—from the semaphoront to the highest rank—have reality and individuality despite not being universals, and that they form a hierarchy of levels, each of which may require different kinds of explanation. Hartmann’s metaphysics thereby provided a philosophical justification for Hennig’s phylogenetic systematics, both as a theory and as a method of classification. (shrink)
Despite recognizing the importance of developing authentic corporate social responsibility (CSR) programs, noticeably absent from the literature is consideration for how employees distinguish between authentic and inauthentic CSR programs. This is somewhat surprising given that employees are essentially the face of their organization and are largely expected to act as ambassadors for the organization’s CSR program (Collier and Esteban in Bus Ethics 16:19–33, 2007 ). The current research, by conducting depth interviews with employees, builds a better understanding of (...) how employees differentiate between authentic and inauthentic CSR programs, and how these judgments influence their perceptions of the organization. We find that employees rely on two different referent standards to form authenticity judgments—the extent to which the image put forth in the CSR program aligns with the organization’s true identity and the extent to which the CSR program itself is developmental. To assess the former, employees draw on cues about resource commitment, alignment between elements of the organization’s CSR program, emotional engagement, justice, and embeddedness. The latter assessments are based on the extent to which the organization adopts a leadership role with regards to its CSR initiatives. We also find that perceived authenticity can lead to positive outcomes such as organizational identification and employee connections. This study contributes to the broad literatures on both CSR and authenticity, as well as more specifically adding to the conversation on authenticity as a potentially valuable lens for enriching business ethics theorizing.

Among the most exciting experiences in our lives are the ones that arouse a magical rapture within us. This may happen when we become engrossed in a musical piece, when dancing becomes ecstatic, when we are passionately in love (or making love) or when we experience an intuitive perception or an altered state of consciousness, get caught by the spell of the infinity of the Universe or the splendor of nature; it can also happen during telepathic contact or in lucid (...) dreams. What I shall try to outline here is a systematic world-view that gives a basis for the interpretation of the special character of those magical actions. A model for the structure of the Universe is shown in which different levels of existence are sequentially telescoped into each other. This model suggests that the different levels of the material and the inner worlds can be in direct connection, thus offering us a new perspective for participating in the process of Creation.
