Wittgenstein and Levinas examines the oft-neglected relationship between the philosophies of two of the most important and notoriously difficult thinkers of the twentieth century. By bringing the work of each philosopher to bear upon the other, Plant navigates between the antagonistic intellectual traditions that they helped to share. The central focus on the book is the complex yet illuminating interplay between a number of ethical-religious themes in both Wittgenstein's mature thinking and Levinas's distinctive account of ethical responsibility.
Plantsuccession is a phenomenon ascribed to vegetation dynamics at the scale of the plant community. The study of plantsuccession implies the analysis of the species involved and their relationships. Depending on the research done, the characteristics of trees have been studied according to either static, dimensional or partial approaches. We have revised the principal theories of succession, the methods of describing structure and development of tree and relationship established between tree species' attributes (...) and their successional status. During studies of succession, we propose that the profile of plant species be completed by including the organizational attributes of their structure as well as their development dynamics. We suggest an approach to the architecture that gives a general overview of the mode of development, revealing, among other things, that a limited number of architectural models may be found in nature. We hypothesize that community dynamics, in succession, may to a certain degree arise from the dynamic nature of plant development. This line of reasoning is in accordance with the current school of thought on process structuralism. (shrink)
The complexity and heterogeneity of causes influencing ecology’s domain challenge its capacity to generate a general theory without exceptions, raising the question of whether ecology is capable, even in principle, of achieving the sort of theoretical success enjoyed by physics. Weber has argued that competition theory built around the Competitive Exclusion Principle (especially Tilman’s resource-competition model) offers an example of ecology identifying a law-like causal regularity. However, I suggest that as Weber presents it, the CEP is not yet a causal (...) regularity. Instead, I argue that the scientific understanding in Tilman’s theory takes a different form. The theory explains through a structure I call “channeling explanation” which does not depend on deduction from general laws, but rather builds on constraints and trade-offs represented in state-space. Recognizing this structure supports the more general point that ecology and other so-called special sciences can reveal novel theoretical approaches to philosophy of science when approached with openness to their uniqueness.

The impact of Foucault's work can still be felt across a range of academic disciplines. It is nevertheless important to remember that, for him, theoretical activity was intimately related to the concrete practices of self-transformation; as he acknowledged: `I write in order to change myself.' 1 This avowal is especially pertinent when considering Foucault's work on the relationship between sex and power. For Foucault not only theorized about this topic; he was also actively involved in the S&M subculture of the (...) 1970s. Although his explicit discussions of S&M are somewhat piecemeal, in this article I will show how they provide a useful point of access into his broader conception of power relations. Having first reconstructed Foucault's quasi-Sartrean account of creative self-transformation — specifically through one's sexuality — I will then explain why his defence of S&M (as embodying `strategic' power) is insufficiently sensitive to the inherent ambiguities of this `game'. Key Words: consent • desire • identity • limits • pleasure • power • role-play • subjectivity • trust. (shrink)
Abstract Wittgenstein?s remarks on religious and magical practices are often thought to harbour troubling fideistic and relativistic views. Unsurprisingly, commentators are generally resistant to the idea that religious belief constitutes a ?language?game? governed by its own peculiar ?rules?, and is thereby insulated from the critical assessment of non?participants. Indeed, on this fideist?relativist reading, it is unclear how mutual understanding between believers and non?believers (even between different sorts of believers) would be possible. In this paper I do three things: (i) show (...) why the fideist?relativist reading of Wittgenstein is not wildly implausible (Sections 1?2); (ii) argue that, despite its initial plausibility, this reading fails to take into account Wittgenstein?s naturalism (Sections 3?4); and (iii) explain what sort of naturalism this is, and how it sheds light on Wittgenstein?s remarks on religious belief (Sections 5?6).

This article examines the issues raised by religious adherents’ wish to express their beliefs in the public domain through, for example, their modes of dress, their performance of public roles, and their response to homosexuality. It considers on what grounds religion might merit special treatment and how special that treatment should be. A common approach to these issues is through the notion of religious identity, but both the idea of religious identity and its use to ground claims against others prove (...) deeply problematic. An alternative and more productive approach is through the notion of harm. People should enjoy the freedom to express their religious convictions subject to the harm principle, but harm should include the undermining of people’s status as free and equal citizens. The article concludes by considering the grounds upon which this alternative approach might recognize religion as special and might justify giving an overriding status to civic equality. (shrink)
According to Levinas, the history of western philosophy has routinely ‘assimilated every Other into the Same’. More concretely stated, philosophers have neglected the ethical significance of other human beings in their vulnerable, embodied singularity. What is striking about Levinas’ recasting of ethics as ‘first philosophy’ is his own relative disregard for non-human animals. In this article I will do two interrelated things: (1) situate Levinas’ (at least partial) exclusion of the non-human animal in the context of his markedly bleak conception (...) of ‘the state of nature’, and (2) drawing on Orwell, Wittgenstein and Gaita, argue that, despite his more positive evaluation of animality (specifically a dog named Bobby), Levinas is guided by a number of anthropomorphic prejudices; not least that the epithet ‘the animal’ can be used in the general singular.

This paper focuses on the idea of the rule of law as found in neo-liberal political and legal theory. The central argument is that it is not possible to produce an account of the rule of law and its basic building blocks in such theories—namely freedom, rights and justice—without reference to a set of shared substantive values. The crucial argument is that if freedom is understood negatively, as the absence of coercion, it is not in fact possible to produce an (...) account of coercion which detaches it from conceptions of the good. The impact of this argument is then analysed in relation to a range of themes, one of the central ones of which is that on the neo-liberal view the welfare state cannot be made compatible with the rule of law. The case for this important view is rejected in the paper. (shrink)
In 1981, after 20 years of teaching and writing philosophy, Derrida claimed that ‘less than ever’ did he ‘know what philosophy is’. Indeed, his ‘knowledge of what ... constitutes the essence of philosophy’ remained ‘at zero degree’. 1 These were not flippant remarks. Rather, Derrida’s avowed uncertainty is part of a more general metaphilosophical view; namely, that ‘Philosophy has a way of being at home with itself that consists in not being at home with itself’. 2 In this article I (...) will critically reconstruct and develop this view, paying particular attention to the ‘institutional’ dimension of contemporary philosophy.

In "Culture and Value" Wittgenstein remarks that the truly "religious man" thinks himself to be, not merely "imperfect" or "ill," but wholly "wretched." While such sentiments are of obvious biographical interest, in this paper I show why they are also worthy of serious philosophical attention. Although the influence of Wittgenstein's thinking on the philosophy of religion is often judged negatively (as, for example, leading to quietist and/or fideist-relativist conclusions) I argue that the distinctly ethical conception of religion (specifically Christianity) that (...) Wittgenstein presents should lead us to a quite different assessment. In particular, his preoccupation with the categorical nature of religion suggests a conception of "genuine" religious belief which disrupts both the economics of eschatological-salvationist hope, and the traditional ethical precept that "ought implies can." In short, what Wittgenstein presents is a sketch of a religion without recompense. (shrink)
On Certainty remains one the mostprovocative and challenging parts ofWittgenstein's intellectual legacy.Philosophers generally read this text as anassault on the traditional sceptic/anti-scepticdebate. But some commentators identifypolitical – specifically `conservative' –sentiments at work here. Others embraceWittgenstein's (alleged) `pluralism', whilethose less enthused think the latter collapsesinto relativism. Although this mixed receptionis, I will argue, partly due to Wittgenstein'sown troubled engagement with the central themesof On Certainty, the real difficultyand value of this text lies in itsintertwining questions of epistemology,religious belief and ethical-politicaljudgement.
Mark Dooley has recently argued (principally against Simon Critchley) that the attempt to establish too strong a ‘connection’ between Jacques Derrida and Emmanuel Levinas not only distorts crucial disparities between their respective philosophies, it also contaminates Derrida’s recent work with Levinas’s inherent ‘political naivety’. In short, on Dooley’s reading, Levinas is only of ‘inspirational value’ for Derrida. I am not concerned with defending Critchley’s own reading of the ‘Derrida–Levinas connection’. My objective is rather to demonstrate, first, the way in which (...) Dooley’s argument hinges upon a misreading of Levinas and Derrida, and, second, why Derrida’s recent thinking is in fact fundamentally Levinasian. Key Words: contingency • guilt • Holocaust • hospitality • institutions • nature • suffering • third party • violence. (shrink)
In his recent article 'Speech and Sensibility: Levinas and Habermas on the Constitution of the Moral Point of View', Steven Hendley argues that Levinas's preoccupation with language as 'exposure' to the 'other' provides an important corrective to Habermas's focus on the 'procedural' aspects of communication. Specifically, what concerns Hendley is the question of moral motivation, and how Levinas, unlike Habermas, responds to this question by stressing the dialogical relation as one of coming 'into proximity to the face of the other' (...) who possesses 'the authority to command my consideration'. Hendley's thesis is bold and provocative. However, it relies on too partial a reading of Levinas's work. In this paper I argue that the sense in which Levinas thinks of 'justifying oneself' cannot be adequately understood in terms of an 'outstretched field of questions and answers'. Rather, Levinas's primary concern is to show how, prior to dialogue, the 'I' is constituted in existential guilt: the violence of simply being-there. (shrink)

This article explores strategy-making modes within organisations. The implications of certain strategy-making modes for the responsible leader as an architect or change agent are highlighted. The study on which this article is based, showed that the use of emergent strategy-making is as prevalent as the use of deliberate strategy-making. This article reports on the thinking of organisational leaders, managers and non-managers regarding strategy-making processes and records empirical findings from mixed method research. It was found that emergent strategy-making is associated with (...) quick response and adaptation to environmental changes, more autonomous decisions and actions, less control and higher intangibility whereas the deliberate strategy is known for its clear objectives, articulated vision and direction and specific ends and means. It is recommended that organisational leaders should take cognisance of the growing use of emergent strategy-making as well as its characteristics in facilitating effective governance. A knowledge and understanding of these characteristics of strategy-making modes should be sought to serve as guideline for organisational leaders who want to be responsive and responsible in all their actions areas for future research.

Notwithstanding his own spiritual inadequacies, Wittgenstein has a profound respect for those capable of living a genuinely religious life; namely, those whose “passionate,” “loving” faith demands unconditional existential commitment. In contrast, he disapproves of those who see religious belief as hypothetical, reasonable, or dependent on empirical evidence. Drawing primarily on Culture and Value, “Lectures on Religious Belief,” and On Certainty, in this essay I defend two claims: (1) that there is an unresolved tension between Wittgenstein's later descriptive-therapeutic approach and the (...) implicit normativity of his conception of genuine/passionate religious belief; and (2) that the demarcation between the latter and its pseudo-religious counterpart is itself problematic. To illustrate these claims I argue that apocalyptic Christian fundamentalism presents a significant challenge to Wittgenstein's taxonomy. Despite these shortcomings, however, I conclude by suggesting that his characterization of religious belief as a “passion” or “love” remains valuable. (shrink)
Many Levinasians are prone to merely assert or presuppose that the Other is ‘radically Other’, and that such Otherness is of patent ethical significance. But building ethics into the very concept of ‘the Other’ seems question-begging. What then, if not mere Otherness, might motivate Levinasian responsibility? In the following discussion I argue that this can best be answered by reading Levinas as a post-Holocaust thinker, preoccupied with how one’s simply being-here constitutes a ‘usurpation of spaces belonging to the other’. Then, (...) drawing on Schutz’s phenomenology, I explain how the resultant usurpatory bad conscience presupposes the embodied ‘interchangeability’ of self and Other. As such, one can be said to ‘usurp’ the Other’s place only insofar as self and Other are not radically different. (shrink)
The aim of the book is two-fold. First of all it is to provide a fair, complete and analytical account of the Neo-liberal conception of the role and function of the state in modern society. The second aim is to provide a critical assessment of some of the central elements of this conception. The book will look at the emphasis of Neo-liberals on procedural and rule governed approaches to the role of the state rather than outcome or end state views (...) of the role of government and to consider how this conception of politics relates to issues such as the rule of law, freedom, justice, rights, the relationship to the market economy, to civil society and to look at the role of government in relation to the provision of welfare and public sector services more generally. It builds up the Neo-liberal case in respect of these aspects of modern society by drawing upon the works of central Neo-liberal thinkers such as Hayek, Mises, Menger, as well as thinkers such as Oakeshott, Nozick and Rotbard who are not directly Neo-liberals but whose works have been important for the development of central Neo-liberal themes. The second part of the book provides what might be regarded as an immanent critique of the Neo-liberal case built up in the first part of the study. It takes Neo-liberal ideas very seriously and shows how incoherences arise within and between those ideas such that a plausible form of Neo-liberalism as opposed to Libertarianism on the one hand and Social Democracy on the other is very difficult to state. The theme of this book is very germane given the considerable debate which is now taking place in the context of the world financial crisis about the appropriate role for the state. (shrink)
In the following paper I shall outline a number of preliminary ideas concerning the relationship between the Holocaust and certain themes which emerge in the work of Emmanuel Levinas. As this relationship is distinctly twofold, my analysis will include both a textual and a rather more speculative component. That is to say, while I shall argue that reading Levinas specifically as a post-Holocaust thinker clarifies a number of his philosophical and rhetorical motifs, so, in turn, does this challenging body of (...) work offer a means by which to re-think both the horror and ethical significance of the Holocaust itself. During the course of my argument I shall additionally refer to the writings of Primo Levi, Jacques Derrida and Martin Heidegger through whom I hope also to establish the central role guilt and confession play in Levinas’s own thinking.

The credibility of digital computer simulations has always been a problem. Today, through the debate on verification and validation, it has become a key issue. I will review the existing theses on that question. I will show that, due to the role of epistemological beliefs in science, no general agreement can be found on this matter. Hence, the complexity of the construction of sciences must be acknowledged. I illustrate these claims with a recent historical example. Finally I temperate this diversity (...) by insisting on recent trends in environmental sciences and in industrial sciences. (shrink)
The harsh consequences of the American plant closing epidemic in recent years on workers, their families, and their communities, has raised widespread ethical and moral concerns. In the early 1970s, a diverse group of academics, social activists, public policy analysts, and special interest organizations developed a number of legislative proposals designed to restrict closings by law. The proposals encountered many formidable obstacles in an increasingly hostile free-market environment. The business community was itself moved to assume some of the burdens (...) precipitated by closures either unilaterally or through collective bargaining. At the same time, powerful business interests tenaciously fought the enactment of mandatory closing restrictions into law. Nevertheless, through a prolonged and tortuous odyssey, the requirements of advanced notice and worker severence pay have now begun to root in law. Their success stands as evidence of a continuing American public policy receptivity to ethics-driven concerns. (shrink)
The paper describes the design and implementation of a plant biodiversity conservation program that was developed under funding and time constraints for diverse ecological, social, and institutional environments. The biodiversity program for alpine meadows and pastures located in the Swiss Canton of the Grisons is used as an example. The design of the sustainable program relied on existing legislation, accounted for limited ecological knowledge and expertise, and considered biodiversity as a common-pool resource. The trend to intensified cultivation of restricted (...) areas required fast action, while the sustainability of the program design had to take into account institutional diversity. Fifteen habitats and plant communities worth conserving were known, and 57 plant species were identified as indicator species for establishing an inventory and for monitoring purposes. A small subset of 16 well known plant species was presented to the farming communities. They were invited to notify the areas in which they observed the presence of these plants. In different regions of the Canton a total number of 39 paraecologists were trained to inspect the areas notified by farmers and to recommend possible incorporation into the Cantonal inventory. This was done once the farmers signed a contract in which they agreed to follow adequate management practices. The farmers received subsidies to compensate for their losses. Communal authorities controlled the fertilizer input and cutting dates, while the paraecologists were trained to monitor plant biodiversity. The program started in 1992 and the initial phase of the inventory was terminated in 1996. At the beginning of 1996, an inventory of 2617.19 ha, most of which are meadows, was taken and managed according to the rules specified in the contract. The program was considered successful because (i) of the size of the area in the inventory, (ii) about 30%of the farmers participated, and (iii) farmers started cultivating previously abandoned farmland.

It is argued that a subject who has an experience as of succession can have this experience at a time, or over a period of time, during which there occurs in him no succession of conscious mental states at all. Various metaphysical implications of this conclusion are explored. One premise of the main argument is that every experience is an experience as of succession. This implies that we cannot understand phenomenal temporality as a relation among experiences, but (...) only as a primitive feature of experience, or else as something analyzable into wholly non-phenomenal terms.

The problem of plant individuality is something which has vexed botanists throughout the ages, with fashion swinging back and forth from treating plants as communities of individuals (Darwin 1800 ; Braun and Stone 1853 ; Münch 1938 ) to treating them as organisms in their own right, and although the latter view has dominated mainstream thought most recently (Harper 1977 ; Cook 1985 ; Ariew and Lewontin 2004 ), a lively debate conducted mostly in Scandinavian journals proves that the (...) issues are far from being resolved (Tuomi and Vuorisalo 1989b ; Fagerström 1992 ; Pan and Price 2001 ). In this paper I settle the matter once and for all, by showing which elements of each side are correct. (shrink)
A familiar slogan in the literature on temporal experience is that ‘a succession of appearances, in and of itself, does not amount to an experience of succession’. I show that we can distinguish between a strong and a weak sense of this slogan. I diagnose the strong interpretation of the slogan as requiring the support of an assumption I call the ‘Seems→Seemed’ claim. I then show that commitment to this assumption comes at a price: if we accept it, (...) we either have to reject the extremely plausible idea that experience is as it seems, or we are forced to provide an account of temporal experience that isn’t compatible with the phenomenology. I conclude by noting that the only plausible interpretation of the slogan is the weak interpretation, and outline a positive account of temporal experience, according to which an appearance of succession requires a succession of appearances.

We analyse managerial discourse in corporate communication (‘CEO-speak’) during a 6-month period following a legitimacy-threatening event in the form of an incident in a German nuclear power plant. As discourses express specific stances expressed by a group of people who share particular beliefs and values, they constitute an important means of restoring organisational legitimacy when social rules and norms have been violated. Using an analytical framework based on legitimacy as a process of reciprocal sense-making and consisting of three levels (...) of analysis which capture the relationship between text and context, we investigate the discourse used by CEOs in their initial and subsequent accounts of the incident. We find that CEOs aim to negotiate a resolution between their initial account and organisational audiences’ incongruent interpretations of the event by adopting an ad hoc normative attitude to stakeholders. This manifests itself in the strategic use of the discourse of stakeholder engagement as a means of signalling change, yet maintaining the status quo. It suggests that CEOs strategically use discourse to manufacture organisational audiences’ consent regarding the continued operation of the nuclear power plant affected by the incident. Our findings contribute to the critical corporate communication literature which regards corporate narrative reporting as a means of consolidating the private interests of corporations, rather than increasing transparency and accountability.

In the final analysis, sustainable agriculture must derive from applied ecology, especially the principle of the regulation of the abundance and distribution of species (and, secondarily, their activities) in space and time. Interspecific competition in natural ecosystems has its counterparts in agriculture, designed to divert greater amounts of energy, nutrients, and water into crops. Whereas natural ecosystems select for a diversity of species in communities, recent agriculture has minimized diversity in favour of vulnerable monocultures. Such systems show intrinsically less stability (...) and resilience to perturbations. Some kinds of crop rotation resemble ecological succession in that one crop prepares the land for successive crop production. Such rotations enhance soil organic processes such as decomposition and material cycling, build a nutrient capital to sustain later crop growth, and reduce the intensity of pest buildup. Species in natural communities occur at discrete points along the r-K continuum of reproductive maturity. Clearing forested land for agriculture, rotational burning practices, and replacing perennial grassland communities by cereal monocultures moves the agricultural community towards the r extreme. Plant breeders select for varieties which yield at an earlier age and lower plant biomass, effectively moving a variety towards the r type. Features of more natural landscapes, such as hedgerows, may act as physical and biological adjuncts to agricultural production. They should exist as networks in agricultural lands to be most effective. Soil is of major importance in agroecosystems, and maintaining, deliberately, its vitality and resilience to agricultural perturbations is the very basis of sustainable land use. (shrink)
Numerous and diverse reports indicate the efficacy of shamanic plant adjuncts (e.g., iboga, ayahuasca, psilocybin) for the care and treatment of addiction, post-traumatic stress disorder, cancer, cluster headaches, and depression. This article reports on a first-person healing of lifelong asthma and atopic dermatitis in the shamanic context of the contemporary Peruvian Amazon and the sometimes digital ontology of online communities. The article suggests that emerging language, concepts, and data drawn from the sciences of plant signaling and behavior regarding (...) “plant intelligence” provide a useful heuristic framework for comprehending and actualizing the healing potentials of visionary plant “entheogens” (Wasson 1971) as represented both through first-person experience and online reports. Together with the paradigms and practices of plant signaling, biosemiotics provides a robust and coherent map for contextualizing the often reported experience of plant communication with ayahuasca and other entheogenic plants. The archetype of the “plant teachers” (called Doctores in the upper Amazon) is explored as a means for organizing and interacting with this data within an epistemology of the “hallucination/perception continuum (Fischer 1975). “Ecodelic” is offered as a new linguistic interface alongside “entheogen” (Wasson 1971).

From the point of view of a dynamic morphology, form is not only the result of process(es) — it is process. This process may be analyzed in terms of two pairs of fundamental processes: growth and decay, differentiation and dedifferentiation. Each of these processes can be analyzed in terms of various modalities (parameters) and submodalities. This paper deals with those of growth (see Table 1). For the purpose of systematits and phylogenetic reconstruction the modalities and submodalities can be considered dynamic (...) characters that have states. Each state of such a dynamic character is a more detailed process, hence not static. For example, determinate growth represents a state of the dynamic character (or modality) of growth duration.The processes of Table 1 can be applied to the whole plant kingdom (although in certain cases only some processes of the whole set may be applicable). Thus, the diversity of plant form is seen as a diversity of process combinations. From this point of view, change in form implies change in the process combination(s). Questions that arise are, for example, the following: Which process combinations actually occur? Which of these are the most frequent? How and why have process combinations changed during ontogeny and phylogeny? (shrink)
Pathological morphogenesis on leaves of Fraxinus ornus (ash) and Solanum lycopersicum (tomato) under the influence of mites (Aceria fraxinivora and Eriophyes cladophthirus respectively) leads to a range of structures whose morphology and development cannot be reduced to the classical categories of plant morphology, but present a heterogeneous continuum which links fundamental structural categories. These findings support the pyramid model of plant construction.
It has recently been asserted that legislative moves to consider plants as ethical subjects are philosophically foolish because plants lack autonomy. While by no means the sole basis or driving criterion for moral behavior, it is possible to directly challenge skeptical attitudes by constructing a human-plant ethics centered on fundamental notions of autonomy. Autonomous beings are agents who rule themselves, principally for their own purposes. A considerable body of evidence in the plant sciences is increasingly recognizing the capacity (...) of plants to assess, perceive, and act on their environment. The primary purpose of their doing so is to generate the conditions for their own flourishing. With these plant purposes in mind, it is evidentially inappropriate to treat plants purely as instruments. In this age of environmental crisis, knowledge of plant intelligence and autonomy opens up a new debate on respecting and promoting the well-being of the plants that make life on Earth possible.

In ecology, if the considered area or space is large, the spatial distribution of individuals of a given plant species is never homogeneous; plants form different patches. The homogeneity change in space or in time (in particular, the related change-point problem) is an important research subject in mathematical statistics. In the paper, for a given data system along a straight line, two areas are considered, where the data of each area come from different discrete distributions, with unknown parameters. In (...) the paper a method is presented for the estimation of the distribution change-point between both areas and an estimate is given for the distributions separated by the obtained change-point. The solution of this problem will be based on the maximum likelihood method. Furthermore, based on an adaptation of the well-known bootstrap resampling, a method for the estimation of the so-called change-interval is also given. The latter approach is very general, since it not only applies in the case of the maximum-likelihood estimation of the change-point, but it can be also used starting from any other change-point estimation known in the ecological literature. The proposed model is validated against typical ecological situations, providing at the same time a verification of the applied algorithms. (shrink)
ABSTRACT: In this article I argue that Hume's empiricism allows for time to exist as a real distinct impression of succession, not, as many claim, merely as a nominal abstract idea. In the first part of this article I show how for Hume it is succession and not duration that constitutes time, and, further, that only duration is fictional. In the second part, I show that according to the way Hume describes the functions of the memory and imagination, (...) it is possible to explain how we are able to perceive a distinct impression of succession.RÉSUMÉ: Dans cet article, je soutiens, à l'encontre de plusieurs, que l'empirisme de Hume conçoit le temps comme une impression réelle et distincte de succession, voire, une idée nominale et abstraite.

À partir de la description de Hume des fonctions de la mémoire et de l'imagination, je montre en second lieu qu'il est possible d'expliquer comment nous sommes capables d'une impression distincte de succession.

Scientists who play the game exploit opportunities and surmount (...) setbacks by adopting strategies and reinventing tactics in order to maximize their winnings and to minimize their losses.

Phytomorphology — if concerned with development — often concentrates on correlative changes of form and neglects the aspects of age, time and clock, although the plant's spatial and temporal organisation are intimately interconnected. Common age as measured in physical time by a physical process is compared to biological age as measured by a biological clock based on a biological process. A typical example for a biological clock on the organ level is, for example, a shoot. Its biological age is (...) measured by the biological time unit of a plastochron, which itself is defined by the cyclic-periodic initiation of the leaves. In a controlled environment biological age may replace physical age. However, biological and physical age are not necessarily linearly convertible into each other. In stationary or steady state conditions the repetitive initiation of any organ, unit or module of an articulate plant or plant modular system may define the biological time unit. A linear — monotonous biological process, e.g. axis elongation, may also define a biological time unit as a certain amount of additional growth, e.g. of length. One may speak of periodical and of continuous plastochron or, perhaps, of plastochron and rheochron. A precise measure of biological age is the generalized plastochron index applying to any modular system and module respectively. However, one should be aware that it is based on two clocks, one of them referring to the periodic process of module initiation for counting the integer plastochrons and the other to the continuous plastochron of module growth for the determination of the fraction of one plastochron. The application of the concepts is restricted to phases of stationary or steady state growth and development. In certain cases of non-stationary or non-steady state conditions a normalized-age concept may apply. (shrink)
In this paper we analyse how the risks associated with research on transgenic plants are regulated in Sweden. The paper outlines the way in which pilot projects in the plant sciences are overseen in Sweden, and discusses the international and national background to the current regulatory system. The historical, and hitherto unexplored, reasons for the evolution of current administrative and legislative procedures in plant science are of particular interest. Specifically, we discuss similarities and differences in the regulation of (...) medicine and plant science, and we examine the tendency towards dichotomizing risk — focusing on social/ethical risks in medicine and biological risks in plant science.

The paper deals with an intellectual and historical approach to the changing meanings of the term “model” in life sciences. The author 1st tries to understand how modeling has gradually spread over life sciences then he particularly focus on the birth of mathematical modeling in this field. This quite new practice offers new insights on the old debate concerning the mathematization of life sciences. Nowadays, through computers, mathematics not only analyze or quantify but model things: what does it mean? The (...) question turns out to be dramatic as far as digital simulation is concerned. That is the reason why he choosed to study a particular case: the history of the individual plant mathematical modeling. On this case, one may discern various epistemological standpoints that caused various reactions to the emergence of computer simulation, from the 50s to the 90s. The author shows that philosophical views often play a role in the history of sciences, especially in the choice of supposed proper mathematical formalisms. This will indicate that contemporary discourses tend to echo each other. That is the reason why he feels authorized to address the Foucault’s concept—épistémè—to denote these convergences between the scientific and the philosophical discourses. Finally, it is suggested that this épistémè gradually is changing because one can currently observe the emergence of a “graphical” thought through these simulation experiments, which tends to replace a more functionalist thought.

In 1987, Chrysler bought American Motors which included a plant in Kenosha, Wisconsin, a city of 72 000. Employing 6 500 workers, most of whom were members of the United Auto Workers (UAW), Chrysler became the city's largest employer. For decades, the UAW had a strong influence on city politics. However, in the 1980s young professionals in Kenosha began challenging this status quo.Chrysler shocked the citizens of Kenosha when their executives announced the closing of their plant within a (...) year. Wisconsin government officials and the UAW believed that Chrysler promised to stay for up to five years; they considered Chrysler's move to be a breach of contract. Chrysler responded that it was their "intention" -- not a contractual agreement -- to stay in Kenosha. From an ethical perspective, just cause, due process and mitigation of harmful effects should be applied in the discussion of a plant closing. (shrink)
Dicotyledons are polarly organised in several ways. In plant morphology polarity, a principle allowing comparison of different plant structures has until yet not been studied. A division** of the vegetative plant in shoot and root as polar structures leads to the distinction of four instead of three basic organs: leaf, shoot axis, root axis and root cap together with the root hairs. The flower is also polarly organised, its poles are formed by the carpels and the stamens. (...) The foliage leaves are also polarly organised which is reflected by the morphological relationship of foliage leaf, stamen and carpel. The stamen uses the hypophyll*** as base of construction and the carpel uses the epiphyll**** as base of construction. Hypophyll and epiphyll are the two poles of the foliage leaf. Root and shoot, the polar entities of the vegetative plant and stamen and carpel, the polar entities of the generative plant, are morphologically correlated. Stamen and carpel can be understood as a combination of the basic organs of vegetative and generative parts of the plant. The basic organs of the generative plant are pollen grain and embryo sack with their gametophytes. The quantitative comparison of variable proportions is supplemented by a qualitative comparison of polarities. The result is, that the organisation type of the dicotyledons can yet be understood as constituted of morphological related parts.* in german Grundorgane. (shrink)
In addition to obviating the use of synthetic agrochemicals and emphasizing farming in accordance with agro-ecological guidelines, organic farming acknowledges the integrity of plants as an essential element of its natural approaches to crop production. For cultivated plants, integrity refers to their inherent nature, wholeness, completeness, species-specific characteristics, and their being in balance with their (organically farmed) environment, while accomplishing their “natural aim.” We argue that this integrity of plants has ethical value, distinguishing integrity of life, plant-typic integrity, genotypic (...) integrity, and phenotypic integrity. We have developed qualitative criteria to ethically evaluate existing practices and have applied these criteria to assess whether current plant breeding and propagation techniques violate the integrity of crop plants. This process has resulted in a design of a holistic, scientific approach of organic plant breeding and seed production. Our evaluation has met considerable criticism from mainstream (crop) scientists. We respond to the following questions: (1). Can ethics be incorporated into objective crop sciences? (2). What is the nature of the intrinsic value of plants in organic farming? We argue that criteria to take integrity into account can only be assessed from a holistic perspective and we show that a holistic approach is needed to design such ethical notions in a consistent way. The ethical notions have been further elaborated by formulating human responsibility and respect towards crop plants. Responsibility and respect can only be shown by providing crop plants the right to be nurtured and to express natural behavior at all levels of integrity. (shrink)
In this article, I explore plant semiosis with a focus on plant learning. I distinguish between the scales and levels of learning conceivable in phytosemiosis, and identify organism-scale learning as the distinguishing question for plant semiosis. Since organism-scale learning depends on organism-scale semiosis, I critically review the arguments regarding whole-plant functional cycles. I conclude that they have largely relied on Uexküllian biases that have prevented an adequate interpretation of modern plant neurobiology. Through an examination of (...) trophic growth in plant roots, I expose some conceptual difficulties in attributing functional cycles to whole-plants. I conclude that the mapping of resource areas in the root system is a learning activity requiring higher-scale sign activity than is possible at the cellular scale, strongly suggesting the presence of organism-scale functional cycles. I do, however, question whether all perception-action cycles in organisms are accompanied with organism-scale semiosis. (shrink)
A case study of growers conception of irrigation strategies indicates that pot plant growers in Scandinavia base their management approaches on experientially based art. The study also indicates that there is a gap between experientially based art and available greenhouse technology. In order to standardize production and produce quality, both the growerâs experience and available technology should be taken into account. In order to achieve this, the present study proposes to arrange reflection on reflection in action with a group (...) of growers by means of the dialogue seminar method. The concept of reflection on reflection in action is novel to horticultural practice. Therefore, we suggest future inter- and multidisciplinary research within this domain. (shrink)
Plant protection problems are simulated by a system of ordinary differential equations with given initial conditions. The sensitivity and resistance of pathogen subpopulations to fungicide mixtures, fungicide weathering, plant growth, etc. are taken into consideration. The system of equations is solved numerically for each set of initial conditions and parameters of the disease and fungicide applications. Optimization algorithms were investigated and a computer program was developed for optimization of these solutions. 14 typical cases of the disease were simulated (...) and optimized in order to determine optimal fungicide treatments. The optimized strategy for fungicide application differs considerably from the commonly used method and seems to be an important new principle in plant protection. The approach developed in this study may be useful for a wide spectrum of purposes in the simulation of leaf diseases. It may also help the biologist to decrease or pinpoint experimental work and analyze its results and is perspective for plant disease control. (shrink)
Certain facts about subjective successions support, I hold, a theory of mind?dependent sensory data. Suppose that no such theory is true and, furthermore, that as one experiences a visual subjective succession, that of which one is visually aware consists typically in a static physical array. Nevertheless one will, I hold, experience a certain change taking place within one's visual field; and under the imagined conditions, it is hard to fathom what this change could be. Various seemingly plausible and helpful (...) suggestions are examined and rejected. I conclude that neither a common?sense realism nor, in fact, any view which rejects mind?dependent sensory data can deal satisfactorily with subjective successions. (shrink)
Plants are interpreted as structural hierarchies which are real systems organized through descending constraints. Types of hierarchical groups in plants are (a) cluster by integration, (b) support through attachment, (c) enclosure by encasement (d) dissipative by input of energy and (e) control through variable state switching. Most plant hierarchies are mixtures of these types which explains a number of paradoxes in plant morphology. The traditional means of identifying levels, i.e., cell, tissues, organs, uses a compositional group which is (...) not a hierarchical group but a similarity feature and so is inadequate for describing hierarchies. Hierarchies can be defined by set theory which is more a description of cognitive than real hierarchies and therefore is of little value in describing plant organization. The hierarchical description of a plant emphasizes the immediate physical status of organization which provide, in turn, a physical explanation of development. (shrink)
Expatriate managers of international businesses in emerging countries often struggle to mobilize their workforces. They sometimes perceive profound cultural differences as a barrier to the progress of their organizations. Some international businesses may adopt a paternalistic attitude toward their employees; but this questionable strategy brings mixed results. Are there ways out of paternalism for international businesses in emerging areas? This paper examines the diverging views held by foreign managers and local personnel of a foreign-owned production plant in Mexico, which (...) managed to mobilize its workforce by building a strong sense of community, allowing a certain form of collective control to replace the paternalistic model, with its bonds of personal allegiance. Contrasting perspectives between Mexican and foreign employees show that intercultural misunderstandings, rather than the peculiarities of the local culture, are the greatest challenge to cooperation.

Data from experiments on Erica × darleyensis and from related observations (Viémont and Beaujard, 1983) are taken for a critical analysis of the proposed model of morphogenetic phenomena. The criteria for judging the coherence of the constructions proposed in plant morphology are based on mathematical constructions deduced from Petri nets, especially elementary nets.
External pressures have changed the context within which CEOs are succeeded. At the same time, chairmen are clear that this responsibility is personal to them and are increasingly changing the nature of the process. Two new models of CEO succession are identified: one where the Board actively partners with the incumbent CEO and the other a crisis model where the Chairman and the Board assure the active management of the succession process. In both cases, best practice is for (...) the Board to develop its own assessment criteria. A 'best practice' profile is suggested. Good assessment processes then focus on understanding the candidate, identifying data gaps, looking at evidence of predicted future performance and identifying development priorities. The final stage of the process is transition planning. A process for CEO succession is proposed and a number of principles for effective succession are put forward. (shrink)
In this paper, I propose an ontological-hermeneutical approach to the question of vegetative life. I argue that, though it is a product of the metaphysical traditionthat from Aristotle to Nietzsche ascribes to the life of plants but a single function, the notion of plant-soul is useful for the formulation of a post-metaphysicalphilosophy of vegetation. Offered as a prolegomenon to such thinking about plants, this paper focuses on the multiplicity of meanings, the obscurity, and thepotentialities inherent in their life.
A geometrical model is proposed that describes the emergence of a primordium at the shoot apex in Dicotyledons. It is based on recent fundamental results on plant morphogenesis, viz.: – the emergence is preceded by the reorganization of the microtubules of the cortical cytoskeleton, leading to a new orientation of the synthesis of the cell wall microfibrils; – the resulting global stress is related to the general orientation of the cell growth.
In recent years an increasing amount of information leaves no doubt that the costs to the victims of plant closures are more than economic. The stress occasioned by job loss often results in ill health. These findings aside, little systematic research has been done of the consequences of unemployment for the spouses of the unemployed. In this article, a comparison is made between the effects of a closure on unemployed male employees and their wives. It is found that both (...) groups suffer a high degree of anxiety over future job prospects and both experience a high level of stress as a result of the closure. However, for wives, anxiety, but not general stress, leads to ill health. For men, neither appears to have health implications: post-closure illness is related to illness prior to the shutdown. In one sense, two months after the closure, it can be argued that the impact of the shutdown was greater on wives than unemployed former employees. (shrink)
Growth of spring barley stands was followed in various conditions. Disposition of the seeds parameters the morphogenetic programme of each individual plant, which will afterwards form the stricture of the young plant stand. Later, individual stopping of tillering is controlled by this stricture. In return, the distribution of these events conditions the structure of the canopy during the shoot lengthening period. In sparse or patchy canopies, weak tillers in stopping of growth are able to survive temporarily.The plant (...) is not reducible to the genotype of its variety. Individual whole plant and plant stand are true organization levels in an ecosystem. It is essential to take their relationships into account throughout the growth for understanding the behaviour of a crop. (shrink)
A determined division wall positioning in each plant cell with respect to the last formed division wall leads to autoreproductive configurations which can simulate plant-like meristems as such with 2/5 phyllotactic patterns. L-map systems are used to generate the corresponding topological wall nets. But in these patterns cells are not six-sided as mostly found in layers. It is shown that wall staggering cannot be a determinate device of the cell itself, nor a randomized dissociation of the cross walls, (...) but results from a physical control with interaction between adjacent cells. It is independent of the cellular program responsible for the appearance of patterns like 2/5 phyllotaxis which is of a pentameric nature. (shrink)
To cope with the water deficit resulting from saline environment, plant cells accumulate three kinds of osmotica: salts, small organic solutes and hydrophillic, glycine-rich proteins. Salts such as NaCl are cheap and available but has ion toxicity in high concentrations. Small organic solutes are assistant osmotica, their main function is to protect cytoplasmic enzymes from ionic toxicity and maintain the integrity of cellular membranes. Hydrophillic, glycine-rich proteins are the most effective osmotica, they have some characteristics to avoid crystallization even (...) in high concentration, but because they are expensive they are not as commonly used as salts or organic solutes. In addition there is the question of whether the genetic information for growth in saline environment is present in all kinds of plants, both halophytes and nonhalophytes. (shrink)
The physiology of plant hormones was one of the most dynamic fields in experimental biology in the 1930s, and an important part of T. H. Morgan's influential life science division at the California Institute of Technology. I describe one episode of plant physiology research at the institution in which faculty member James Bonner discovered that the B vitamin thiamin is a plant growth regulator, and then worked in close collaboration with the Merck pharmaceutical firm to develop it (...) as a growth-boosting agrichemical. This episode allows one to draw continuities between certain fields of life science in the United States circa 1940 and the biotechnology industry today, and also foregrounds a number of similarities between plant physiology of the late 1930s and the molecular biology of the period.

During the second half of the XX century drug addiction ceased to be only the epiphenomenon of crime, prostitution and a number of other social-relations deviation, and became a constant value of post-industrial society and at the end of XX century turned into a global problem of mankind. A new form of mass neurosis shows that drug dependence is nowadays socially conditioned mental degeneration, caused by activation of unconscious collective archetypes that are experienced depending on the corresponding situation. The identification (...) of the sacred plant soma/haoma with the marihuana enables us to not only to make clear the light and the dark sides of this archetype, but also to figure out that the reduction of the drug addiction problem, to the acceptable for the society level, is possible only if a man will be able to satisfy his “life-asserting, vital needs”, if he will be able to regain the true meaning of life.

For all its subtle differences, Husserl scholarship on time-consciousness has reached a consensus that Husserl’s theory underwent a significant interpretiveimprovement starting around 1908 / 1909. On this advance, which concerned the intentional structure and directedness of absolute consciousness, I have cautioned against reading Augustine’s theory of time as a philosophical predecessor to Husserl’s. In a recent “confrontation” with my efforts, Roger Wasserman tried to defend a reading of Augustine’s influence on Husserl’s theory of time by criticizing my reading of Augustine (...) and Husserl. This reply to Wasserman’s challenge (i) reestablishes my reservations about attempts to claim a relation between Augustine and Husserl on time-consciousness, (ii) defends the standard interpretation of the development of Husserl’s theory of time-consciousness, and (iii) raises several critical questions about Wasserman’s Neoplatonic or Augustinian reading of Husserl on time-consciousness.

Abstract This paper argues that in modern (agro)biotechnology, (un)naturalness as an argument contributed to a stalemate in public debate about innovative technologies. Naturalness in this is often placed opposite to human disruption. It also often serves as a label that shapes moral acceptance or rejection of agricultural innovative technologies. The cause of this lies in the use of nature as a closed, static reference to naturalness, while in fact “nature” is an open and dynamic concept with many different meanings. We (...) propose an approach for a dynamic framework that permits an integrative use of naturalness in debate, by connecting three sorts of meaning that return regularly in the arguments brought forward in debate; cultural, technological, and ecological. We present these as aspects of nature that are always present in the argument of naturalness. The approach proposes a dynamic relation between these aspects, formed by gradients of naturalness, which in turn are related to ethical concerns. In this way we come to an overview that makes it possible to give individual arguments a relative place and that does justice to the temporality of the concept of nature and the underlying ethical concerns stakeholders have in respect to innovation in agriculture.
