David Lewis's best-systemanalysis of laws of nature is perhaps the best known sophisticated regularity theory of laws. Its strengths are widely recognized, even by some of its ablest critics. Yet it suffers from what appears to be a glaring weakness: It seems to grant an arbitrary privilege to the standards of our own scientific culture. I argue that by reformulating, or reinterpreting, Lewis's exposition of the best-systemanalysis, we arrive at a view that is free (...) of this weakness. The resulting theory of laws has the surprising consequence that the term "law of nature" is indexical. (shrink)
In social science, one objection to causal analysis is that the assumption of the closure of the system makes the analysis too narrow in scope, that is, it considers only 'closed' and 'hermetic' systems thus neglecting many other external influences. On the contrary, systemanalysis deals with complex structures where every element is interrelated with everything else in the system. The question arises as to whether the two approaches can be compatible and whether causal (...)analysis can be integrated into the broader framework of systemanalysis. This article attempts a negative answer on the grounds of fundamental differences in their assumptions and suggests using systemanalysis as a post-hoc comparative tool. (shrink)
This paper attempts to outline some of the important concepts and ideas used in systemanalysis which is taken to be a general mode of analysis used in all sciences. Systems are seen from three perspectives: (1) that involving the relationship between system and environment, (2) that involving interaction between several systems, and (3) that involving one type of system composed of other types of systems. The writers also discuss the concepts "structure" and "equilibrium" as (...) they apply to systemanalysis, the point being made that the use of these concepts in the social sciences has often been vague or even incorrect.

A new approach to the analysis of the neuroendocrine system (NES) is suggested. It is based on the fact of structural and metabolic determination of any effect on cell and cell aggregates. The principle of a common communication channel in the NES is formulated and a possible method of its formalization is proposed.
Terms loaded with informational connotations are often employed to refer to genes and their dynamics. Indeed, genes are usually perceived by biologists as basically ‘the carriers of hereditary information.’ Nevertheless, a number of researchers consider such talk as inadequate and ‘just metaphorical,’ thus expressing a skepticism about the use of the term ‘information’ and its derivatives in biology as a natural science. First, because the meaning of that term in biology is not as precise as it is, for instance, in (...) the mathematical theory of communication. Second, because it seems to refer to a purported semantic property of genes without theoretically clarifying if any genuinely intrinsic semantics is involved. Biosemiotics, a field that attempts to analyze biological systems as semiotic systems, makes it possible to advance in the understanding of the concept of information in biology. From the perspective of Peircean biosemiotics, we develop here an account of genes as signs, including a detailed analysis of two fundamental processes in the genetic information system (transcription and protein synthesis) that have not been made so far in this field of research. Furthermore, we propose here an account of information based on Peircean semiotics and apply it to our analysis of transcription and protein synthesis. (shrink)
The WTO Dispute Settlement System (DSS) has been the object of many studies in politics, law, and economics focusing on institutional design problems. This paper contributes to such studies by accounting for the argumentative nature and sophisticated features of the DSS through a philosophical analysis of the procedures through which it is articulated. Jürgen Habermas's discourse theory is used as a hermeneutic device to disentangle the types of ‘orientations’ (compromise, consensus, and mutual understanding) pertaining to DSS procedures. We (...) show that these latter are oriented primarily to put the parties in a position to reach mutual understanding. Such an orientation is no mere idiosyncrasy of the DSS but is the only one consistently conducive to the WTO's general aims, in response to the various types of disputes that may arise between its Members. Before closing, we bring our procedural considerations to bear on the reform proposals of the DSS. (shrink)
In this paper we introduce a notation system for the infinitary derivations occurring in the ordinal analysis of KP + Π₃-Reflection due to Michael Rathjen. This allows a finitary ordinal analysis of KP + Π₃-Reflection. The method used is an extension of techniques developed by Wilfried Buchholz, namely operator controlled notation systems for RS∞-derivations. Similarly to Buchholz we obtain a characterisation of the provably recursive functions of KP + Π₃-Reflection as <-recursive functions where < is the ordering (...) on Rathjen's ordinal notation system J(K). Further we show a conservation result for $\Pi _{2}^{0}$-sentences. (shrink)
The report entitled An Analysis of the Canadian Research and Development System for Agriculture/Food which was presented to the Science Council of Canada in July, 1991 contains many far-reaching recommendations for revisions of the research and educational components of the Agriculture/Food System in Canada. The report calls for research of holistic and interdisciplinary nature. It calls for determination of research priorities by broadly constituted committees which would include reporesentaitves heretofore not included in the process of decisionmaking regarding (...) scientific research. In addition, it calls for restructuring of the agricultural education system. The Co-editors of this Journal, believe that these recommendations should be wildely discussed and, therefore, requested publication of the Executive Summary of this Report. (shrink)
Several key areas in modeling the cardiovascular and respiratory control systems are reviewed and examples are given which reflect the research state of the art in these areas. Attention is given to the interrelated issues of data collection, experimental design, and model application including model development and analysis. Examples are given of current clinical problems which can be examined via modeling, and important issues related to model adaptation to the clinical setting.
Much of the discussion on business ethics is philosophical in nature. There is no lack of theories and ideals on moral reasoning. What is missing is translating these moral theories and principles into specific, operational procedures that can indicate a proper course of action. Although most business actions are routine and do not raise serious ethical questions, many people experience difficulty in applying their personal moral principles to specific business decisions in ethically-dilemmatic situations.This study seeks to develop a framework that (...) can be utilized to implement personal moral reasoning based on the teleological theory of Utilitarianism and the deontological theory of Ross''s Prima Facie Duties in the business decision-making process. The central feature in the framework is a point-system that quantities the ethical worth of a proposed business action and determines whether the action would be ethically desirable if taken. It provides an objective element in an otherwise qualitative ethical inquiry process. This study also illustrates practical applications of the system by analyzing the ethical implications of a proposed action where foreign bribery is involved. (shrink)
The Zhouyi is the first of the Chinese classics and has, since medieval times, fascinated scholars from different parts of the world, who have produced numerous studies and expressed a dazzling array of views on its nature. It is argued that the Zhouyi has retained its exalted status and enduring appeal largely because it is an open book amenable to all kinds of appropriations and manipulations, and its openness comes from its being a semiotic system whose principle of composition (...) warrants unlimited interpretations. Through a semiotic-cum-philosophical inquiry, it is shown that the Zhouyi is first and foremost a system of representation, and because of its unique structure and principle of signification it forms an open hermeneutic space with infinite possibilities of interpretation.

This paper focuses on the implications for the economic analysis of growth and innovation in relation to the NSI concept being part of the evolutionary research programme. We show that the modern evolutionism associates descriptive and theoretical works following specific methodological reasons. It is then argued that the NSI concept has a particularly important place within the evolutionary research programme, because it challenges and is challenged by the new neoclassical theories of growth concerning the explanation of the convergence/divergence process (...) among the developed economies. It is also very powerful in order to elaborate arguments for technological policies. In addition, its evaluation cannot be disconnected from its theoretical content. We illustrate why the NSI will not be helpful for the neoclassical theories of growth because the assumptions it relies on are not be accepted by these theories. (shrink)

Some theorists who emphasize the complexity of biological and cognitive systems and who advocate the employment of the tools of dynamical systems theory in explaining them construe complexity and reduction as exclusive alternatives. This paper argues that reduction, an approach to explanation that decomposes complex activities and localizes the components within the complex system, is not only compatible with an emphasis on complexity, but provides the foundation for dynamical analysis. Explanation via decomposition and localization is nonetheless extremely challenging, (...) and an analysis of recent cognitive neuroscience research on memory is used to illustrate what is involved. Memory researchers split between advocating memory systems and advocating memory processes, and I argue that it is the latter approach that provides the critical sort of decomposition and localization for explaining memory. The challenges of linking distinguishable functions with brain processes is illustrated by two examples: competing hypotheses about the contribution of the hippocampus and competing attempts to link areas in frontal cortex with memory processing.

This is a contribution to construction of a research roadmap for future cognitive systems, including intelligent robots, in the context of the euCognition network, and UKCRC Grand Challenge 5: Architecture of Brain and Mind. -/- A meeting on the euCognition roadmap project was held at Munich Airport on 11th Jan 2007. This document was in part a response to discussions at that meeting. An explanation of why specifying requirements is a hard problem, and why it needs to be done, along (...) with some suggestions for making progress, can be found in this presentation: http://www.cs.bham.ac.uk/research/projects/cosy/papers/#pr0701 "What's a Research Roadmap For? Why do we need one? How can we produce one?" Working on that presentation made me realise that certain deceptively familiar words and phrases frequently used in this context (e.g. "robust". "flexible", "autonomous") appear not to need explanation because everyone understands them, whereas in fact they have obscure semantics that needs to be elucidated. Only then can we understand what the implications are for research targets. In particular, they need explanation and analysis if they are to be used to specify requirements and research goals, especially for publicly funded projects. -/- First draft analyses are presented here. In the long term I would like to expand and clarify those analyses, and to provide many different examples to illustrate the points made. This will probably have to be a collaborative research activity. (shrink)

An analysis of the ethical impacts of the use of anAutomatic Milking System (AMS) is employed as a casestudy to illustrate the use of a form of bioethicalanalysis in technology assessment. The approach isbased on the Ethical Matrix, where `impacts' areassessed in terms of (lack of) respect for threeethical principles as applied to interest groups. Inthis case, only impacts on dairy cows are examined,and principally in terms of their behaviouralfreedom.In contrast to traditional milking systems, AMS, inprinciple, allow cows (...) to present for milkingvoluntarily. So with AMS, it is claimed that dairymanagement relies on the autonomous interaction of thecow with her environment. (shrink)
Wegner, Giuliano, and Hertel (1985) defined the notion of a transactive memory system (TMS) as a group level memory system that “involves the operation of the memory systems of the individuals and the processes of communication that occur within the group (p. 191). Those processes are the collaborative procedures (“transactions”) by which groups encode, store, and retrieve information that is distributed among their members. Over the past 25+ years, the conception of a TMS has progressively garnered an increased (...) interest among social and organizational psychologists, communication scholars, and management theorists (Ren & Argote 2011). But there remains considerable disagreement about how exactly Wegner’s appeal to group memory should be understood. My goal in this paper is contribute to this debate, by articulating more clearly the value of conceptualizing groups as TMSs. This value, I argue, consists in providing us with a blueprint for how to explain group memory in terms of collective information-processing mechanisms. Collective information-processing mechanisms are dependent on, and interact with, the brain-bound information-processing of individuals, but cannot be reduced to the latter. In my analysis, I lean on extant accounts of mechanistic explanation in the philosophy of science (Bechtel & Richardson 1993; Machamer, Darden, & Craver 2000; Wimsatt 2007) that have been used to analyze the explanatory practices of psychology and cognitive neuroscience (Bechtel 2008, 2009). Based on my reconstruction of Wegner’s conceptualization of a TMS, I argue that the reality of emergent group cognition is compatible with its mechanistic explanation. More generally, my analysis shows that group cognition cannot be reduced to individual cognition, while avoiding the false dilemma between “wholism” and “nothing but-ism” which has hampered traditional construals of the “group mind” thesis (Allport 1968).

The paper describes a methodology to be used for analysis and design of human activity systems. The methodology is based on an analysis of the decision settings whereas most other decision analysis methodologies are analysing the process. The decision concept is analysed and discussed. A distinction between programmed and programmable as well as non-programmed and non-programmable decisions is proposed. A classification of different information types for decision making is presented. A methodology based on a systemic and systematic (...)analysis of the information requirements of an organization is proposed. This methodology also indicates organizational discrepancies and information imbalances. The methodology focuses the settings of the decisions on all levels of organizations. The methodology can be regarded as a dynamic, learning system. The author proposes further research on the individuals decision making abilities. (shrink)
Rational analysis (Anderson 1990, 1991a) is an empiricalprogram of attempting to explain why the cognitive system isadaptive, with respect to its goals and the structure of itsenvironment. We argue that rational analysis has two importantimplications for philosophical debate concerning rationality. First,rational analysis provides a model for the relationship betweenformal principles of rationality (such as probability or decisiontheory) and everyday rationality, in the sense of successfulthought and action in daily life. Second, applying the program ofrational analysis (...) to research on human reasoning leads to a radicalreinterpretation of empirical results which are typically viewed asdemonstrating human irrationality.

This paper examines the notion that psychology is autonomous. It is argued that we need to distinguish between (a) the question of whether psychological explanations are autonomous, and (b) the question of whether the process of psychological discovery is autonomous. The issue is approached by providing a reinterpretation of Robert Cummins's notion of functional analysis (FA). A distinction is drawn between FA as an explanatory strategy and FA as an investigative strategy. It is argued that the identification of functional (...) components of the cognitive system may draw on knowledge about brain structure, without thereby jeopardizing the explanatory autonomy of psychology.

Philosophers of mind, both in the conceptual analysis tradition and in the empirical informed school, have been implicitly neglecting the potential conceptual role of the Peripheral Nervous System (PNS) in understanding sensory and perceptual states. Instead, the philosophical as well as the neuroscientific literature has been assuming that it is the Central Nervous System (CNS) alone, and more exactly the brain, that should prima facie be taken as conceptually and empirically crucial for a philosophical analysis of (...) such states This is the first monograph that focuses on the PNS and its constitutive role in sensory states, including pain, mechanoception, proprioception, tactile perception, and so forth. -/- The author argues that the brain-centeredness of current philosophy of mind is a prejudice, and proposes a series of original ways in which classic puzzles in the philosophy of mind can be solved once the hypothesis that PNS is a constitutive element of mental states is taken seriously. The author calls this “the Peripheral Mind Hypothesis”, and employs it in a vast range of issues, such as functionalism, physicalism, mental content, embodiment, as well as some issues in neuroethics. -/- Making equal use of conceptual analysis, empirical data from neuroscience, first-person phenomenological data, and philosophical speculation, this work offers a fresh look at, and novel solutions to many philosophical problems.

Having entered into the problem structuring methods, system dynamics (SD) is an approach, among systems’ methodologies, which claims to recognize the main structures of socio-economic behaviors. However, the concern for building or discovering strong philosophical underpinnings of SD, undoubtedly playing an important role in the modeling process, is a long-standing issue, in a way that there is a considerable debate about the assumptions or the philosophical foundations of it. In this paper, with a new perspective, we have explored theory (...) of knowledge in SD models and found strange similarities between classic epistemological concepts such as justification and truth, and the mechanism of obtaining knowledge in SD models. In this regard, we have discussed related theories of epistemology and based on this analysis, have suggested some implications for moderating common problems in the modeling process of SD. Furthermore, this research could be considered a reword of system dynamics modeling principles in terms of theory of knowledge. (shrink)
This book is written by someone who holds that physics and the metaphysics of cause and law broadly strive to achieve a common goal: to undstand what our physical system is constituted by, and both how, and why it evolves in the way that it does. It seems to me that the primary tools of the scientist are empirical evidence, mathematics, and although this is perhaps less appreciated, imagination - these are fundamental to any great scientific breakthrough. For us, (...) the metaphysicians, imagination, science, and a priori reasoning form the foundation of our enquiries. I believe that for the metaphysician, reasoning without due consideration of science will inevitably lead to unjustified, and probably false conclusions. In this thesis I provide an analysis of a number of metaphysics of cause and law, as well as a conceptual analysis of both, to show how closely a consistent account of causation must be linked with laws of nature. I then attempt to give metaphysics explanations of our best scientific theories(in particular, least action principles and the general theory of relativity) in terms of the metaphysical views discussed, in order to judge their compatibility with science. I conclude that any successful metaphysic will be a broadly Humean one. (shrink)
Contemporary theory is increasingly concerned with macro-micro integration. An attempt is made to integrate these levels of analysis in Durkheim's theory of egoistic suicide. Does Durkheim's theory, which is a social systemanalysis designed to explain differences in suicide rates between groups, have micro implications for specifying which particular individuals within the group will take their lives? In attempting to answer this question by exploring the causal linkages between integration and suicide, Durkheim's theory of egoistic suicide was (...) revealed not to be a singular theory but rather contained several different explanations. The numerous interpretations have resulted from his incompletely specified, inconsistent, unsystematized, and inadequately tested theory. These ambiguities also account for the historically inconsistent research findings that have limited sociologists' ability to advance beyond Durkheim's century-old formulations. Further areas for new research and illustrative hypothesis are suggested. (shrink)
This article illustrates the important scientific role that a systems approach might play within the social sciences and humanities, above all through its contribution to a common language, shared conceptualizations, and theoretical integration in the face of the extreme (and growing) fragmentation among the social sciences (and between the social sciences and the natural sciences). The article outlines a systems theoretic approach, actor-system-dynamics (ASD), whose authors have strived to re-establish systems theorizing in the social sciences (after a period of (...) marginalization since the late 1960s). This is done, in part, by showing how key social science concepts are readily incorporated and applied in social systemanalysis. (shrink)
Both the constructive and predicative approaches to mathematics arose during the period of what was felt to be a foundational crisis in the early part of this century. Each critiqued an essential logical aspect of classical mathematics, namely concerning the unrestricted use of the law of excluded middle on the one hand, and of apparently circular \impredicative" de nitions on the other. But the positive redevelopment of mathematics along constructive, resp. predicative grounds did not emerge as really viable alternatives to (...) classical, set-theoretically based mathematics until the 1960s. Now we have a massive amount of information, to which this lecture will constitute an introduction, about what can be done by what means, and about the theoretical interrelationships between various formal systems for constructive, predicative and classical analysis.

Most writers now recognize that mental health policy and the mental health system are extremely resistant to real changes that reflect genuine biopsychosocial paradigms of mental disorder. Writers bemoaning the intransigence of the mental health system tend to focus on a small analytical level, only to find themselves mired in the rationalities of the existing system. Problems are acknowledged to be system-wide, yet few writers have used a method of analysis appropriate for systemic problems. Drawing (...) upon the General System Theory (GST) analytical perspective, this article advances a systematic approach to understand the mental health system and to facilitate the development of reform strategies that recognize the system's complexity and changing nature. The article first discusses the failure of major reform efforts in the mental health system and the limitations of mainstream analysis of mental health politics and policies with respect to the objectives of analysis and reform. This article describes how systems thinking has thus far influenced the study of the mental health policy and politics system, and argues that a systemic perspective is profitable for reconceiving the mental health system, enabling a fresh basis for the development of reform strategies. The mental health system should be seen as a social system influenced by larger political and economic dimensions, not just as a 'delivery system' scientifically constructed by neutral experts. Furthermore, the policy planning process should be viewed as part and parcel of a mental health system modeled as complex and dynamic. The systemic perspective outlined here should help both to clarify the value-based objectives that we hold for the system and, consequently, to plan for the strategic reforms that have so far eluded us.

In biology, the ‘ecological orientation' rests on a commitment to examining systems, and the conceptual challenge of defining that system now employs techniques and concepts adapted from diverse disciplines (i.e., systems philosophy, cybernetics, information theory, computer science) that are applied to biological simulations and model building. Immunology has joined these efforts, and the question posed here is whether the discipline will remain committed to its theoretical concerns framed by the notions of protecting an insular self, an entity demarcated from (...) its environment, or will shift its focus of interest to a wider context. An ecological perspective emphasizes the interchange between the organism and its environment, the processing of information, and the regulation arising from responses to this larger context. Moving from the first attempts at modeling the immune system as a closed network, immunologists have joined the general interest in systems analysis, and that move might portend a significant shift to an open, more holistic consideration of immune regulation. *Received December 2006; revised August 2007. †To contact the author, please write to: Center for Philosophy and History of Science, Boston University, 745 Commonwealth Ave., Boston, MA 02215; e-mail: ait@bu.edu.

After experiments with various economic systems, we appear to have conceded, to misquote Winston Churchill that "free enterprise is the worst economic system, except all the others that have been tried." Affirming that conclusion, I shall argue that in today's expanding global economy, we need to revisit our mind-sets about corporate governance and leadership to fit what will be new kinds of free enterprise. The aim is to develop a values-based model for corporate governance in this age of globalization (...) that will be appropriate in a variety of challenging cultural and economic settings. I shall present an analysis of mental models from a social constructivist perspective. I shall then develop the notion of moral imagination as one way to revisit traditional mind-sets about values-based corporate governance and outline what I mean by systems thinking. I shall conclude with examples for modeling corporate governance in multi-cultural settings and draw tentative conclusions about globalization. (shrink)

This study examines the similarities and differences in pre- and post-Sarbanes-Oxley corporate ethics codes and codes of conduct using the framework of structuration theory. Following the passage of the Sarbanes-Oxley (SOX) legislation in 2002 in the United States, publicly traded companies there undertook development and revision of their codes of ethics in response to new regulatory requirements as well as incentives under the U.S. Corporate Sentencing Guidelines, which were also revised as part of the SOX mandates. Questions that remain are (...) whether these new or revised codes are effective means of communicating changed ethical foci and attitudes in organizations. Centering resonance analysis (CRA) is used to identify differences and similarities across time and industries by analyzing word networks of 46 pre- and post-SOX corporate codes of ethics. Analyses focus on content and structure of generated word networks as well as resulting factors that emerged from the texts. Results are interpreted from the structuration perspective that content and structure of codes are constrained and enabled by system structures while they function to produce and reproduce those structures. Results indicate that corporate codes of ethics are formal discourses of ethics, laws, and control. Code structure has changed across time, with an increased emphasis on compliance in post-SOX codes. Implications for research and practice are discussed in light of findings. (shrink)
If connectionism is to be an adequate theory of mind, we must have a theory of representation for neural networks that allows for individual differences in weighting and architecture while preserving sameness, or at least similarity, of content. In this paper we propose a procedure for measuring sameness of content of neural representations. We argue that the correct way to compare neural representations is through analysis of the distances between neural activations, and we present a method for doing so. (...) We then use the technique to demonstrate empirically that different artificial neural networks trained by backpropagation on the same categorization task, even with different representational encodings of the input patterns and different numbers of hidden units, reach states in which representations at the hidden units are similar. We discuss how this work provides a rebuttal to Fodor and Lepore's critique of Paul Churchland's state space semantics. (shrink)
David Lewis has proposed an analysis of lawhood in terms of membership of a system of regularities optimizing simplicity and strength in information content. This article studies his proposal against the broader background of the project of Humean supervenience. In particular, I claim that, in Lewis's account of lawhood, his intuition about small deviations from a given law in nearby worlds (in order to avoid backtracking and epiphenomena) leads to the conclusion that laws do not support (certain) counterfactuals (...) and do not bestow nomic necessity on (certain) facts induced by these laws. Support of counterfactuals and nomic necessity, however, are widely held to be important aspects of the concept of lawhood. In my view, therefore, it is not possible to abandon these criteria in any satisfactory analysis of the notion of laws of nature. In a final section, I suggest that the whole project of Humean supervenience is misleading. It does not sufficiently take notice of the important role that reasoning about contrary-to-fact situations plays in modern scientific practice. (shrink)
As climate policy decisions are decisions under uncertainty, being based on a range of future climate change scenarios, it becomes a crucial question how to set up this scenario range. Failing to comply with the precautionary principle, the scenario methodology widely used in the Third Assessment Report of the International Panel on Climate Change (IPCC) seems to violate international environmental law, in particular a provision of the United Nations Framework Convention on Climate Change. To place climate policy advice on a (...) sound methodological basis would imply that climate simulations which are based on complex climate models had, in stark contrast to their current hegemony, hardly an epistemic role to play in climate scenario analysis at all. Their main function might actually consist in ‘foreseeing future ozone-holes’. In order to argue for these theses, I explain first of all the plurality of climate models used in climate science by the failure to avoid the problem of underdetermination. As a consequence, climate simulation results have to be interpreted as modal sentences, stating what is possibly true of our climate system. This indicates that climate policy decisions are decisions under uncertainty. Two general methodological principles which may guide the construction of the scenario range are formulated and contrasted with each other: modal inductivism and modal falsificationism. I argue that modal inductivism, being the methodology implicitly underlying the third IPCC report, is severely flawed. Modal falsificationism, representing the sound alternative, would in turn require an overhaul of the IPCC practice. (shrink)

has a wide range of options in choosing a health care system. Rational choice of a system depends on analysis and prioritization of the basis moral goals of equitable access to all citizens, the just sharing of financial costs between well and ill, respect for the values and choices of subscribers and patients, and efficiency in the delivery of costworthy care. These moral goals themselves, however, tell us little about what health care system the United States (...) should have. Equitable access does not demand a level and scope of care for the poor equal to that rationally chosen by the middle class, and there are ways within mixed systems, though not easy ways, to achieve a fair distribution of costs between well and ill. Despite pluralistic systems' apparent advantage in allowing subscribers to choose their own forms of rationing, problems in translating serious long-term subscriber choices into actual medical practice may be greater in pluralistic than in unitary systems. Final choice of a system hinges primarily on peculiar historical facts about U.S. political culture, not on moral principle.

In the 1940s, Georges Canguilhem has established the concept of biological normativity on the level of the organism in his key work on “ The Normal and the Pathological ”. We would like to present a contemporary analysis of Canguilhem’s work, set it in context with more recent results from the field of complexity and immunology, and evaluate the problematic whether normativity is a genuine capacity of the organism. Based on Canguilhem’s conditions of the definition of biological normativity, we (...) show that the immune system as one of the complex systems of the living equally shares the capacity to be normative. We will then conclude that normativity can also be conceptually independently displayed on the level of complex systems of the living. (shrink)
A two strain HIV/AIDS model with treatment which allows AIDS patients with sensitive HIV-strain to undergo amelioration is presented as a system of non-linear ordinary differential equations. The disease-free equilibrium is shown to be globally asymptotically stable when the associated epidemic threshold known as the basic reproduction number for the model is less than unity. The centre manifold theory is used to show that the sensitive HIV-strain only and resistant HIV-strain only endemic equilibria are locally asymptotically stable when the (...) associated reproduction numbers are greater than unity. Qualitative analysis of the model including positivity, boundedness and persistence of solutions are presented. The model is numerically analysed to assess the effects of treatment with amelioration on the dynamics of a two strain HIV/AIDS model. Numerical simulations of the model show that the two strains co-exist whenever the reproduction numbers exceed unity. Further, treatment with amelioration may result in an increase in the total number of infective individuals (asymptomatic) but results in a decrease in the number of AIDS patients. Further, analysis of the reproduction numbers show that antiretroviral resistance increases with increase in antiretroviral use. (shrink)
As a rule, Hayek has not been treated kindly by scholars. One would expect that a political theorist and economist of his stature would be charitably, if not sympathetically, read by commentators; instead, Hayek often elicits harsh dismissals. This is especially true of his fundamental ideas about the evolution of society and reason. A reader will find influential discussions in which his analysis is described as “dogmatic,” “unsophisticated,” and “crude.” In this chapter I propose to take a fresh start, (...) sketching a sympathetic interpretation of Hayek’s accounts of social evolution and mind as fundamental to his thinking. My basic claim is that Hayek’s views on social evolution and reason are not only intimately bound together, but they also depend on his analyses of complex orders, scientific explanations of such orders, and the place of rules in complex orders. Because so few commentators recognize that his claims about evolution are embedded in a system of ideas,1 most misunderstand him. (shrink)
During the past several decades, linguists have developed and applied widely techniques which enable them, to a considerable extent, to determine and state the structure of natural languages without semantic reference. It is of interest to inquire seriously into the formality of linguistic method and the adequacy of whatever part of it can be made purely formal, and to examine the possibilities of applying it, as has occasionally been suggested,s to a wider range of problems. In order to pursue these (...) aims it is first necessary to reconstruct carefully the set of procedures by which the linguist derives the statements of a linguistic grammar from the behaviour of language users, distinguishing clearly between formal and experimental in such a way that grammatical notions, appearing as definienda in a constructional system, wM be formally derivable for any language from a fixed sample of linguistic material upon which the primitives of the system are experimentally defined. The present paper will be an attempt to formalize a certain parts of the linguist's generalized syntax language. From another point of view, this paper is an attempt to develop an adequate notion of syntactic category within an inscriptional nominalistic framework. The inscriptional approach seems natural for linguistics, particularly in view of the fact that an adequate extension of the results of this paper will have to deal with the problem of homonymity, i.e., with a statement of the conditions under which tokens of the same type must be assigned to different syntactic classes. It will appear below that the calculus of individuals can often supply quite simple solutions to constructional.. (shrink)
Thomas Pogge has argued that typical citizens of affluent nations participate in an unjust global order that harms the global poor. This supports his conclusion that there are widespread negative institutional duties to reform the global order. I defend Pogge’s negative duty approach, but argue that his formulation of these duties is ambiguous between two possible readings, only one of which is properly confined to genuinely negative duties. I argue that this ambiguity leads him to shift illicitly between negative and (...) positive duties, and ultimately to overstate the extent of the negative ones. I also argue that recognition of this ambiguity makes it possible to draw a meaningful distinction between the relevant positive and negative duties, and that Pogge’s analysis can therefore be revised in a way that reveals substantial negative institutional duties to the global poor, albeit less extensive ones than Pogge asserts. In order to demonstrate this, I discuss two aspects of the global order that Pogge has criticized: the system of intellectual property rights in pharmaceuticals and the rights of de facto rulers to dispose of a nation’s natural resources. In each case, although I do not specify the relevant negative institutional duties precisely, I try to identify intelligible questions whose answers would reveal genuinely negative duties and show that their likely answers are distinct from the conclusions asserted by Pogge and suggested by his analysis.

According to Suszko’s Thesis, there are but two logical values, true and false. In this paper, R. Suszko’s, G. Malinowski’s, and M. Tsuji’s analyses of logical twovaluedness are critically discussed. Another analysis is presented, which favors a notion of a logical system as encompassing possibly more than one consequence relation. [A] fundamental problem concerning many-valuedness is to know what it really is. [13, p. 281].
This paper examines key aspects of Allan Gibbard's psychological account of moral activity. Inspired by evolutionary theory, Gibbard paints a naturalistic picture of morality mainly based on two specific types of emotion: guilt and anger. His sentimentalist and expressivist analysis is also based on a particular conception of rationality. I begin by introducing Gibbard's theory before testing some key assumptions underlying his system against recent empirical data and theories. The results cast doubt on some crucial aspects of Gibbard's (...) philosophical theory, namely his reduction of morality to anger and guilt, and his theory of “normative governance.” Gibbard's particular version of expressivism may be undermined by these doubts.

In this compelling analysis David Pears examines the foundations of Hume's theory of the mind as presented in the first book of the Treatise. Past studies have tended to take one of two extreme views: that Hume relies exclusively on a theory of meaning, or that he relies exclusively on a theory of truth and evidence. Steering a middle course between these positions, Pears argues that Hume's theory of ideas serves both functions. He examines in detail its application to (...) three difficult problems: causation, personal identity, and sense perception. Hume's solutions, Pears argues, are not theories that can be given a place in standard classification of philosophical theories, but rather depend upon a subtle form of naturalism not altogether unlike Wittgenstein's naturalism. A clearly written and argued study, Hume's System will be of special interest to students and scholars of the history of philosophy. (shrink)
Starting from R. K. Merton's now classic criticism of 'holistic' functionalism, i.e. of a functionalism which postulates social unity, universality and functional in-dispensability, the author stresses certain implications of this criticism more than they have been stressed hitherto. Classical and holistic functionalism) from H. Spencer, B. Malinowski, A. R. Radcliffe-Brown, etc to T. Parsons, postulates certain total unities (a global culture, an integrated system, etc.) in which each item (existence, actions, structures, etc.) is considered and defined on the grounds (...) of its consequences for the maintenance of the system as a whole; therefore holistic functionalism as a method is, in effect, the study of the consequences of the system on the items that compose it, since each of these items is defined within the sphere of the system and of its integrative functions. Merton's 'neo-functionalism', on the other hand, is remarkable not only in that it takes into account the 'dysfunctional' and 'nonfunctional' consequences of certain items on the system, but more especially because, within the context of functional analysis, it stresses the possible existence of structural substitutes and alternatives of functions, and therefore of latent structures which are foreign to objective functional consequences, as well as being able to deal with unanticipated and unexpected items and their consequences on the system. 'Neo-functionalism', which is susceptible of further development, is not limited to the study of the consequences of the system on its items: it can also reverse this scheme and study the consequences of certain items on the system. Merton's criticism of holistic functionalism therefore implies a broadening of the scientific resources of this method and a renewal of its interpretative scheme, thanks to which functional analysis ceases to appear as 'the* method of explaining sociology as a science, and becomes an interpretative method which complements the analysis of social structures and relations. Seen in this light the concept of structure becomes emancipated and independent of the concept of system and function; whereas, within the framework of universal functionalism, it was ancillary to the concept of function. Finally, latent structures and unconscious structures, conditions of possibility and subjective dispositions are favourable to social structures and social relations, not excluding those that are neither visible nor observable. This analysis, the author notes, is extremely meaningful and has great possibilities of development, especially in view of the structuralism recently to be noted in the human and social sciences: anthropology, history, linguistics, etc. (shrink)
A glimpse of the new application of Buddhist logic in the seventeenth century leads us to reflect about our approach to logic in a given religious tradition: Should we isolate a logical system from the very context that has given rise to the genesis and development of such an intellectual apparatus? Methodologically, we do have the legitimate right to approach Buddhist logic from a purely logical point of view. However, when we study the actual use of Buddhist logic in (...) the seventeenth-century anti-Christian polemic, an analysis of its intentional application allows us to conclude that Buddhist logic in the context of controversy is primarily apologetic. Therefore, with a methodological concern, I suggest that philosophers and logicians should reconsider the apologetic nature of logic in any given religious tradition. (shrink)
This paper provides a new analysis of e - trust , trust occurring in digital contexts, among the artificial agents of a distributed artificial system. The analysis endorses a non-psychological approach and rests on a Kantian regulative ideal of a rational agent, able to choose the best option for itself, given a specific scenario and a goal to achieve. The paper first introduces e-trust describing its relevance for the contemporary society and then presents a new theoretical (...) class='Hi'>analysis of this phenomenon. The analysis first focuses on an agent’s trustworthiness , this one is presented as the necessary requirement for e-trust to occur. Then, a new definition of e-trust as a second-order-property of first-order relations is presented. It is shown that the second-order-property of e-trust has the effect of minimising an agent’s effort and commitment in the achievement of a given goal. On this basis, a method is provided for the objective assessment of the levels of e-trust occurring among the artificial agents of a distributed artificial system. (shrink)
Abstract This paper addresses the role that argumentation schemes and argument visualization software tools can play in helping to find and counter objections to a given argument one is confronted with.

PDF version This talk explores three concepts of system in engineering: systems theory, systems approach, and systems engineering. They are exemplified in three dimensions of engineering: science, design, and management. Unifying the three system concepts is the idea of function: functional abstraction in theory, functional analysis in design, and functional requirements in management. Signifying what a system is for, function is a purposive notion absent in physical science, which aims to understand nature. It is prominent in (...) engineering, which aims to transform nature for serving the wants and needs of people. (shrink)
Food is a basic human need and therefore a basic human right. While food output has increased to a level where there is enough food produced to feed the world, still millions starve.

Focusing on the impact of a dominant world food supply (...) class='Hi'>system on indigenous systems (particularly through the rise of science, technology, and monopoly capital), considerations relating to environmental use and food production and distribution are raised.

Critical legal scholarship has so far been concerned primarily with trashing or deconstructing the belief clusters of "liberalism". Negative posturing of this kind is not the only feature of the movement, though. Roberto Unger has dreamt up a sociopolitical vision that presents an "empowered democracy". An important element of his "empowered democracy" is a new system of rights. Part 1 of my essay contains an analysis of the notion of a subjective right. I argue that both Hohfeld's fundamental (...) legal conceptions and Unger's various rights can be described by a simple deontic relation that I define as RIGHT. I then discuss a set of normative criteria that can help us evaluate systems of rights. Part 2 [to appear in the following issue -- ed.] contains a detailed critique of Unger's system of rights based on these normative criteria. The tenet of this part is that Unger's system of rights is contradictory, opaque, impracticable, costly, and not fully backed by what Unger offers as a background justification for it. (shrink)
Network analysis is a fundamental approach to the study of social structure. This chapter traces its development, distinguishing characteristics, and analytic principles. It emphasizes the intellectual unity of three research traditions: the anthropological concept of the social network, the sociological conception of social structure as social network, and structural explanations of political processes. Network analysts criticize the normative, categorical, dyadic, and bounded-group emphases prevalent in many sociological analyses. They claim that the most direct way to study a social (...) class='Hi'>system is to analyze the pattern of ties linking its members. By analyzing complex hierarchical structures of asymmetric ties, they study power, stratification, and structural change. (shrink)
In two recent papers Perez Laraudogoitia has described a variety of supertasks involving elastic collisions in Newtonian systems containing a denumerably infinite set of particles. He maintains that these various supertasks give examples of systems in which energy is not conserved, particles at rest begin to move spontaneously, particles disappear from a system, and particles are created ex nihilo. An analysis of these supertasks suggests that they involve systems that do not satisfy the mathematical conditions required of Newtonian (...) systems at the time the supertask is due to be completed, or else they rely on the application of the time-reversal transformation to states which are not well-defined. Consequently, it is unjustified to conclude that the paradoxical results are arising from within the framework of Newtonian mechanics. In the last part of this article, we discuss various aspects of the physics of these supertasks. (shrink)
The scientific methodology underlying model-building is critically investigated. The modeling views of Popper and Samuelson and their prototypes are critically examined in the light of the theme of the moral law of unity of knowledge and unity of the world-system configured by the meta-epistemology of organic unity of knowledge. Upon such critical examination of received methodology of model-building in economics, the extended perspective?namely of integrating the moral law derived from the divine roots as the meta-epistemology?is rigorously studied. The example (...) of the Islamic prerogative in interpreting the holistic world-system through model-building in economics is highlighted. A religio-philosophical approach is adopted to exemplify some approaches in Islamic model-building. An especial focus is placed here on grassroots types of financing and activities. The critique of these models within the existing Islamic scholarship is carried out. The result is new dimensions of macroeconomic analysis that emanate in a logical way from the meta-epistemological approach, and oppose the mainstream ideas, both in received and Islamic economic thinking as of now.

This study examines the system-deciding principle of economic rationality for its logical soundness and effects in global practice. Analysis demonstrates the fallacious structure of the underlying assumptions of homo economicus across theories and institutions, and explains how cumulative destruction of global economic, social, and ecological life systems follows from its life-blind mechanism. Higher-order concepts of life-capital, life-value efficiency, and life-good supply and demand are then defined to bring economic rationality into coherence with terrestrial and human life requirements.
This paper has three goals: (i) to show that the foundational program begun in theBegriffsschrift, and carried forward in theGrundlagen, represented Frege's attempt to establish the autonomy of arithmetic from geometry and kinematics; the cogency and coherence ofintuitive reasoning were not in question. (ii) To place Frege's logicism in the context of the nineteenth century tradition in mathematical analysis, and, in particular, to show how the modern concept of a function made it possible for Frege to pursue the goal (...) of autonomy within the framework of the system of second-order logic of theBegriffsschrift. (iii) To address certain criticisms of Frege by Parsons and Boolos, and thereby to clarify what was and was not achieved by the development, in Part III of theBegriffsschrift, of a fragment of the theory of relations.

My paper responds to certain themes of Professor John McMurtry's recent book, Unequal Freedoms: The Global Market as an Ethical System. Although I am in general sympathy with McMurtry's penetrating critique of conventional market theory and practice, I find Unequal Freedoms ambivalent on the critical question of whether endorsing and enacting the life-value code McMurtry proposes would require only a mitigation of the principles and definitive activities of the competitive market system or whether significant reforms within the (...) class='Hi'>system would have to be deep structural ones. It is argued that the second alternative is inescapable. I defend my perspective from the point of view of a philosophical analysis of orthodox or neo-classical theory-construction about the competitive market order. In particular, I examine three fundamental principles of such modelling: the maximization of the satisfaction of self-interest, the unboundedness of consumer desire for material goods, and the distribution of monetized wealth. In order for McMurtry's "civil commons" to survive, the practice of each of these principles would need to be radically modified. However, in doing so, competitive capitalism would lose its essential identity as a socio-economic order. (shrink)
The system of sevenfold predication of the Jainas, while an invaluable tool in expounding the Jaina doctrine of "non-onesidedness" (Anekāntavāda), has also been criticized for being unsystematic and contradictory. In particular, the fourth predication has been suggested to embrace a kind of irrationality. An analysis is provided here that makes clear the logical basis underlying the seven predications. An interpretation is also offered of the problematic fourth predication that renders the system free from contradiction, and it is (...) suggested that this interpretation best captures the positive spirit of Anekāntavāda.

The widespread idea that infinitesimals were “eliminated” by the “great triumvirate” of Cantor, Dedekind, and Weierstrass is refuted by an uninterrupted chain of work on infinitesimal-enriched number systems. The elimination claim is an oversimplification created by triumvirate followers, who tend to view the history of analysis as a pre-ordained march toward the radiant future of Weierstrassian epsilontics. In the present text, we document distortions of the history of analysis stemming from the triumvirate ideology of ontological minimalism, which identified (...) the continuum with a single number system. Such anachronistic distortions characterize the received interpretation of Stevin, Leibniz, d’Alembert, Cauchy, and others. (shrink)
Three distinctly different interpretations of Aristotle?s notion of a sullogismos in Prior Analytics can be traced: (1) a valid or invalid premise-conclusion argument (2) a single, logically true conditional proposition and (3) a cogent argumentation or deduction. Remarkably the three interpretations hold similar notions about the logical relationships among the sullogismoi. This is most apparent in their conflating three processes that Aristotle especially distinguishes: completion (A4-6)reduction(A7) and analysis (A45). Interpretive problems result from not sufficiently recognizing Aristotle?s remarkable degree of (...) metalogical sophistication to distinguish logical syntax from semantics and, thus, also from not grasping him to refine the deduction system of his underlying logic. While it is obvious that Aristotle most often uses ?sullogimos? to denote a valid argument of a certain kind, we show that at Prior Analytics A4-6, 7, 45 Aristotle specifically treats a sullogismos as an elemental argument pattern having only valid instances and that such a pattern then serves as a rule of deduction in his syllogistic logic. By extracting Aristotle?s understanding of three proof-theoretic processes, this paper provides new insight into what Aristotle thinks reasoning syllogistically is and, moreover, it resolves three problems in the most recent interpretation that takes a sullogismos to be a deduction.

Biological self reference idioms in brain-centered or nervous-system-centered self determination of the consious Self reveal an interesting contrast with biological self-determination by immunological self/non-self discrimination. This contrast is both biological and epistemological. In contrast to the consciousness conscious of itself, the immunological self-determination imposes a protective mechanism against self-recognition (Coutinho et al. 1984), which adds to a largely unconscious achievement of the biological Self (Popper 1977; Medawar 1959). The latter viewpoint is in contrast with the immunological Self-determination as an (...) essentially cognitive process as expressed in the analysis of Tauber (1994). Comparison of the immune system in vertebrates and invertebrates, according to new biological insights, has contributed to a better understanding of the relative role of innate (or inherited) immunity versus immunity acquired during each individual life. Also in this respect, immunological self-achievement shows both a striking analogy and a fundamental discrepancy with the activity of the nervous system. The analysis of immunological Self/non-self discrimination versus brain-centered self-determination adds to the understanding of the function paradigm in biological self-reference idioms, especially when regarding the importance of the connectivity notion in both systems. Adopting functional explanatory schemes for understanding immunological self-non-self discrimination, as well as for the understanding of functional mapping of the brain at (conscious) activity (Friston et al. 1993; Frith et al. 1995), forwards the notion of effective/functional connectivity. Network connectivity not only is a primary question in solving the dimensionality question for immunological ‘idiotypic networks’ (Jerne 1974a, b; 1984), it may also have an important value in describing phase transitions in the development of both immune and nervous systems.

Mathematical proofs generally allow for various levels of detail and conciseness, such that they can be adapted for a particular audience or purpose. Using automated reasoning approaches for teaching proof construction in mathematics presupposes that the step size of proofs in such a system is appropriate within the teaching context. This work proposes a framework that supports the granularity analysis of mathematical proofs, to be used in the automated assessment of students' proof attempts and for the presentation of (...) hints and solutions at a suitable pace. Models for granularity are represented by classifiers, which can be generated by hand or inferred from a corpus of sample judgments via machine-learning techniques. This latter procedure is studied by modeling granularity judgments from four experts. The results provide support for the granularity of assertion-level proofs but also illustrate a degree of subjectivity in assessing step size. (shrink)
This study used a laboratory experiment with monetary incentives to test the impact of three personal factors (moral reasoning, value orientation and risk preference), and three situational factors (the presence/absence of audits, tax inequity, and peer reporting behavior), while controlling for the impact of other demographic characteristics, on tax compliance. Analysis of Covariance (ANCOVA) reveals that all the main effects analyzed are statistically significant and robustly influence tax compliance behavior. These results highlight the importance of obtaining a proper understanding (...) of these factors for developing effective policies for increasing the level of compliance, and indicate that standard enforcement polices based on punishment alone should be supplemented by an information system that would acquaint tax payers with the compliance level of other tax payers; reinforce the concept of fairness of the tax system among tax payers; and develop programs that enhance and appeal to a taxpayer''s moral conscience and reinforce social cohesion.

We propose an analysis of the notion of model as crucially related to the notion of point of view. A model in this sense would always suggest a certain way of looking at a real system, a certain way of thinking about it and a certain way of acting upon it. We focus on System Dynamics as a paradigmatic case with respect to many of the features and problems we can find in the field of modelling and (...) simulation. We analyse in detail some of those features. All of them would be present in many other cases of construction and use of models. Furthermore, they would support the thesis that a model can be fruitfully understood as offering a point of view capable of improving our own points of view over a certain system. The point of view offered by the model could include both non-conceptual and conceptual contents, it would have a complex structure and behaviour, and it would have direct consequences on the decisions made by the subjects adopting that point of view.

Justice system reform is being implemented in Japan. The number of attorneys ( bengoshi ) has substantially increased and concerns have been raised about the impact on the profession's quality and ethics. The profession has called for a slowdown in the increase. Does the increase really adversely affect legal ethics in Japan? Should the pace of the reform be slowed down, from the perspective of maintaining legal ethics? This paper begins to answer these questions through empirical analysis of (...) (1) whether there is an increase in cases of ethical concerns; and (2) whether such an increase (if any) is caused by the increase in bengoshi . The paper then investigates whether there is an over-supply of bengoshi . It concludes with a discussion of the negative impact that a slowdown of the increase may have on access to justice and the bengoshi profession's (ethical) responsibilities. (shrink)
Biological psychiatry has been dominated by a psychopharmacologically-driven neurotransmitter dysfunction paradigm. The objective of this paper is to explore a reductionist assumption underlying this paradigm, and to suggest an improvement on it. The methods used are conceptual analysis with a comparative approach, particularly using illustrations from the history of both biological psychiatry and molecular biology. The results are that complete reduction to physicochemical explanations is not fruitful, at least in the initial stages of research in the medical and life (...) sciences, and that an appropriate (non-reducible) integrative principle - addressing a property of the whole system under study - is required for each domain of research. This is illustrated in Pauling's use of a topological integrative principle for the discovery of the functioning of proteins and in Watson and Crick's use of the notion of a genetic code as an integrative principle for the discovery of the structure of genes. The neurotransmitter dysfunction paradigm addresses single molecules and their neural pathways, yet their interactions within the CNS as a whole seem most pertinent to mental disorders such as schizophrenia. The lack within biological psychiatry of an integrative principle addressing a property of the CNS as a whole may be responsible for the empirical failure of orthomolecular psychiatry, as well as for the central role that serendipity has played in the study of mental disorders, which is dominated by the neurotransmitter paradigm. The conclusion is that research in biological psychiatry may benefit from using, at least initially, some integrative principle(s) addressing a property of the CNS as a whole, such as connectionism or a hierarchical notion.

Whenever an adequate theory is found in science, we will still be left with two questions: why this theory rather than some other theory, and how should this theory be interpreted? I argue that these questions can be answered by a theory of system relations. The basic idea is that fundamental characteristics of systems, viz. those arising from the general systemic nature of those systems, cannot be comprehended with the aid of discipline-specific methods. The systems theory required should commence (...) with an analysis of the qualitatively different relations possible between systems, because it is precisely the nature of those relations that determines the basic structures of systems. That the theory of the fundamental system relations and their ontological and epistemological implications is indeed able to provide the answers sought is demonstrated in theoretical physics and Plessner's analysis of the basic structures of plant, animal and human being.

This paper represents the attempt to define a methodology that can evaluate the degree to which companies'' information systems correspond to needs determined by the objectives of sustainability the firm imposes on itself. The result is the creation of a general model which define the correct approach to evaluating information systems – a model which should be adapted to the specificity of each single company which intends to adopt it. In the chart indicated, we obviously have not considered activities connected (...) to the implementation of the survey system, which are particular to each company''s situation. The first part of the paper consists of an overall introduction to the approach that has been used to assess the (MIS) of Granarolo, one of the Italian companies involved. The case study contains a profile of the company, the analysis of its MIS referred to the three dimensions of sustainability, and an evaluation of the strong points and issues to be developed. This approach to evaluate the gap between desired requirements of an information system for sustainability and current data available in a firm, has proved its consistency and usefulness. It helps to understand where data are, which dimensions, spheres, stakeholders account for and what is the level of integration between different information systems existing in the firm. (shrink)
Ranking systems such as The Times Higher Education’s World University Rankings and Shanghai Jiao Tong University’s Academic Rankings of World Universities simultaneously mark global status and stimulate global academic competition.

Findings indicate some support that both inter-institutional stratification and organizational segmentation predict global status. (shrink)
The scope of this essay is to introduce and explain the methodology underlying the Lanza Foundation Protocol for the analysis of clinical cases. The essay is divided in three parts. Part one examines the Protocol's methodology within the whole evolutionary framework of argumentation in bioethics.

Part two describes the system of argumentation which serves as a frame for both approaches, namely, the normative and the hermeneutical. (...) Finally, the third part presents in an analytic fashion the operations which define the Protocol itself. The Protocol is the result of an interdisciplinary effort and it provides a detailed grid for analyzing and tackling the ethical components of clinical cases. The Protocol is primarily directed toward Ethics Committees in their consulting activity, yet it has been proven of considerable importance at an educational level also, particular in continuing education programs for health care professionals.

When external groups accuse a business organization of unethical practices, managers of the accused organization usually offer a communicative response to attempt to protect their organization's public image. Even though many researchers readily concur that analysis of these communicative responses is important to our understanding of business and society conflict, few investigations have focused on developing a theoretical framework for analyzing these communicative strategies used by managers. In addition, research in this area has suffered from a lack of empirical (...) investigation. In this paper we address both of these weaknesses in the existing literature. First, we explicate Impression Management Theory as an appropriate framework for studying organizational communicative responses, paying particular attention to the concept of accounts. Second, we critique previous investigations of organizational accounts and discuss the major contributions of our study. Third, we propose a coding system and content analyze the accounts offered by managers from 21 organizations that were recently the targets of consumer boycotts. Finally, we report the results of our empirical investigation and discuss ethical issues related to organizational accounts. (shrink)
The dynamics of single populations up to ecosystems, are often described by one or a set of non-linear ordinary differential equations. In this paper we review the use of bifurcation theory to analyse these non-linear dynamical systems. Bifurcation analysis gives regimes in the parameter space with quantitatively different asymptotic dynamic behaviour of the system. In small-scale systems the underlying models for the populations and their interaction are simple Lotka-Volterra models or more elaborated models with more biological detail. The (...) latter ones are more difficult to analyse, especially when the number of populations is large. Therefore for large-scale systems the Lotka-Volterra equations are still popular despite the limited realism. Various approaches are discussed in which the different time-scale of ecological and evolutionary biological processes are considered together. (shrink)
A geometric approach to quantum mechanics with unitary evolution and non-unitary collapse processes is developed. In this approach the Schroedinger evolution of a quantum system is a geodesic motion on the space of states of the system furnished with an appropriate Riemannian metric. The measuring device is modeled by a perturbation of the metric. The process of measurement is identified with a geodesic motion of state of the system in the perturbed metric. Under the assumption of random (...) fluctuations of the perturbed metric, the Born rule for probabilities of collapse is derived. The approach is applied to a two-level quantum system to obtain a simple geometric interpretation of quantum commutators, the uncertainty principle and Planck's constant. In light of this, a lucid analysis of the double-slit experiment with collapse and an experiment on a pair of entangled particles is presented. (shrink)

One of the most vexed issues in income tax policy is how family or household status should affect tax liability. This article suggests a general approach for thinking about the treatment of households in the fiscal system generally under a utilitarian social welfare norm. The United States fiscal rules considered include those not only in the income tax but under Social Security, Medicare, and safety net programs. Among the recommendations that emerge from the analysis are (1) recognizing couples (...) for tax and transfer purposes without limitation to those that are married, (2) reducing the fiscal system's current distributional bias in favor of one-earner couples and its discouraging work by secondary earners, and (3) providing significantly more favorable treatment of households with children than of those with similar resources but no or fewer children, without limiting this more favorable treatment, in the manner of present U.S. law, to relatively poor households.

A formal system for , based on a game-theoretic analysis of the ukasiewicz prepositional connectives, is defined and proved to be complete. An Herbrand theorem for the predicate calculus (a variant of some work of Mostowski) and some corollaries relating to its axiomatizability are proved. The predicate calculus with equality is also considered.
Deep inference is a natural generalisation of the one-sided sequent calculus where rules are allowed to apply deeply inside formulas, much like rewrite rules in term rewriting. This freedom in applying inference rules allows to express logical systems that are difficult or impossible to express in the cut-free sequent calculus and it also allows for a more fine-grained analysis of derivations than the sequent calculus. However, the same freedom also makes it harder to carry out this analysis, in (...) particular it is harder to design cut elimination procedures. In this paper we see a cut elimination procedure for a deep inference system for classical predicate logic. As a consequence we derive Herbrand's Theorem, which we express as a factorisation of derivations. (shrink)

The general public and environmental policy makers often perceive management actions of environmental managers as science, when such actions are, in fact, value judgments about when to intervene in natural processes. The choice of action requires ethical as well as scientific analysis because managers must choose a normative outcome to direct their intervention. I examine a management case study involving prescribed burning of sagebrush (Artemisia tridentata) communities in south-central Montana (USA) to illustrate how to teach students to ethically evaluate (...) a management action by precisely identifying: 1) the proposed management action, 2) the deficiency of the system to be remedied by the action, 3) the stakeholders affected by the action, and 4) the category and type of values affirmed in the management action. Through such analysis, students are taught to recognize implicit and explicit value judgments associated with management actions, identify stakeholders to whom managers have legitimate ethical obligations, and practice a general method of ethical analysis applicable to many forms of environmental management.

The properties of the phosphate uptake system of the cyanobacterium Anacystis nidulans have been studied during the transition from a phosphate-deficient non-growing state to a non-deficient growing state. In the phosphate-deficient state the high affinity phosphate transport system in the cell membrane is extremely adaptive. As a result of these adaptive features the phosphate transport system cannot be described by determinate, fixed parameters, because the transport system is influenced by the measurement of the uptake process itself. (...) When the growing state has been initiated by a persisting phosphate pulse, the transport system rapidly loses its adaptive features and can then be characterized by determinate parameters that remain unchanged for a long period of time, even if no uptake occurs in that time. Depending on the amount of phosphate stored during a pulse the cell makes a choice between slow or fast growth. In the latter case the light harvesting and energy converting machinery is completely reorganized before growth commences. Thereby the components of this machinery conform to each other and to the stable properties of the phosphate transport system. It is suggested that the mutual adjustment of these adaptive energy converting subunits is guided by attractors that function as the final cause for the development of the whole system.An application of this model to an analysis of the selforganization of aquatic ecosystems is discussed.
