Trees architectural study shows gradients in the meristematic activity. This activity is described by the number of internodes per growth unit, which is considered as the output of a dynamic random process. Several species were observed, which led us to propose and then estimate some mathematical models. Computing the functioning of a tree in a given environment therefore involves finding the probability function of the meristems and following the evolution of the parameters of this law along the botanical gradients (order, (...) trend, acrotony) within its architecture.

Animal and human studies suggest that parenting style is transmitted from one generation to the next. The hypotheses of this study were that a mother’s rearing experiences would predict her own parenting resources and current maternal mood, motivation to care for her offspring, and relationship with her parents would underlie this association. In a subsample of 201 first-time mothers participating in the longitudinal Maternal Adversity, Vulnerability and Neurodevelopment project, we assessed a mother’s own childhood maltreatment and rearing experiences using the (...) Childhood Trauma Questionnaire and the Parental Bonding Instrument. At 6 months postpartum, mothers completed questionnaires on parenting stress, symptoms of depression, maternal motivation, and current relationship with their own parents. The sample consisted of mostly high socioeconomic status mothers recruited from Montréal or Hamilton, Canada, with an age range from 18 to 43 years. More severe maltreatment and less supportive rearing by the mother’s parents predicted increased parenting stress at 6 months. These associations were mediated through distinct psychosocial pathways: maltreatment on parenting stress through symptoms of depression ; maternal rearing on parenting stress through maternal motivation and symptoms of depression ; and paternal rearing on parenting stress through current relationship with the father. Maternal rearing experiences predict a mother’s own parenting resources though distinct psychosocial pathways, including depressed mood, maternal motivation, and social support. (shrink)

A travers une phénoménologie où l'art éclaire le réel, à travers son choix des auteurs et des oeuvres qu'il a commentés, le philosophe Henri Maldiney (1912-2013) a proposé un décentrement du regard et du savoir propres à renouveler l'étude du paysage.

Despite its theoretical importance, little is known about how semantic memory structure facilitates and constrains creative idea generation. We examine whether the semantic richness of a concept has both benefits and costs to creative idea generation. Specifically, we tested whether cue set size—an index of semantic richness reflecting the average number of elements associated with a given concept—impacts the quantity (fluency) and quality (originality) of responses generated during the Alternate Uses Task (AUT). Across four studies, we show that low-association, sparse, (...) AUT cues benefit originality at the cost of fluency compared to high-association, rich, AUT cues. Furthermore, we found an interaction with individual differences in fluid intelligence in the low-association AUT cues, suggesting that constraints of sparse semantic knowledge can be overcome with top-down intervention. Our findings indicate that semantic richness differentially impacts the quality and quantity of generated ideas, and that cognitive control processes can facilitate idea production when conceptual knowledge is limited.

In the Caribbean as in many other areas costly biomedical resources and personnel are limited, and more and more people are turning to alternative medicine and folk practitioners for health care. To meet the goal of providing health care for all, research on nonbiomedical therapies is needed, along with legal recognition of folk practitioners to establish standards of practice.

Two experiments examine the effects of unreportable hints on anagram solving performance and on solvers' subjective experience of insight. In Experiment 1, after seeing a hint presented too briefly to identify, participants solved anagrams preceded by the solution fastest and solved anagrams preceded by unrelated hints slowest. Participants' “warmth” ratings for solution hints were more insight-like than those for unrelated hints. In Experiment 2 a hint, or no hint, was presented at one of three different exposure durations . Participants benefited (...) from solution-relevant hints that were either unreportable or reportable, but showed a cost only for unrelated hints that were reportable. Participants' ratings of their insight experiences showed that unreportable solution and semantically related hints produced more insight-like experiences than did unrelated hints. The results suggest that unreportable processing of solution-related information is important for the insight experience. (shrink)

The moral significance of preserving natural environments is not entirely an issue of rights and social utility, for a person’s attitude toward nature may be importantly connected with virtues or human excellences. The question is, “What sort of person would destroy the natural environment--or even see its value solely in cost/benefit terms?” The answer I suggest is that willingness to do so may well reveal the absence of traits which are a natural basis for a proper humility, self-acceptance, gratitude, and (...) appreciation of the good in others.

The federal government's introduction in 1983 of DRG‐based reimbursement for Medicare patients shook the entire health care industry into the vigorous and dramatic cost containment efforts which today are reshaping health care in America.

This book is the most comprehensive treatment available of one of the most urgent - and yet in some respects most neglected - problems in bioethics: decision-making for incompetents. Part I develops a general theory for making treatment and care decisions for patients who are not competent to decide for themselves. It provides an in-depth analysis of competence, articulates and defends a coherent set of principles to specify suitable surrogate decisionmakers and to guide their choices, examines the value of advance (...) directives, and investigates the role that considerations of cost ought to play in decisions concerning incompetents. Part II applies this theoretical framework to the distinctive problems of three important classes of individuals, many of whom are incompetent: minors, the elderly and psychiatric patients. The authors' approach combines a probing analysis of fundamental issues in ethical theory with a sensitive awareness of the concrete realities of health care institutions and the highly personal and individual character of difficult practical problems. Its broad scope will appeal to health professionals, moral philosophers and lawyers alike. (shrink)

Minimizing the costs that others impose upon oneself and upon those in whom one has a fitness stake, such as kin and allies, is a key adaptive problem for many organisms. Our ancestors regularly faced such adaptive problems (including homicide, bodily harm, theft, mate poaching, cuckoldry, reputational damage, sexual aggression, and the infliction of these costs on one's offspring, mates, coalition partners, or friends). One solution to this problem is to impose retaliatory costs on an aggressor so that the aggressor (...) and other observers will lower their estimates of the net benefits to be gained from exploiting the retaliator in the future. We posit that humans have an evolved cognitive system that implements this strategy – deterrence – which we conceptualize as a revenge system. The revenge system produces a second adaptive problem: losing downstream gains from the individual on whom retaliatory costs have been imposed. We posit, consequently, a subsidiary computational system designed to restore particular relationships after cost-imposing interactions by inhibiting revenge and motivating behaviors that signal benevolence for the harmdoer. The operation of these systems depends on estimating the risk of future exploitation by the harmdoer and the expected future value of the relationship with the harmdoer. We review empirical evidence regarding the operation of these systems, discuss the causes of cultural and individual differences in their outputs, and sketch their computational architecture.

In response to rapidly rising health care costs in the United States, federal and state governments and private industry are instituting numerous and diverse cost-containment plans. As devices for coping with a scarcity of resources, such plans present serious challenges to physicians' traditional single-minded devotion to patient welfare. Those which contain costs by directly limiting medical options or by controlling physicians' daily clinical decisions can threaten the quality of medical care by allowing economic authorities to make essentially medical judgments. In (...) contrast, other plans coax compliance by arranging incentives, e.g., offering financial rewards for successful cost containment. While they allow for clinical freedom, these plans create conflicts between physicians' fiduciary obligations to their patients and the competing interests of the payers. Such conflicts arise as physicians try to work within governmental or corporate cost containment policies, and also as they attempt to streamline clinical efficiency. Throughout, issues of justice emerge as physicians seek to reconcile their own patients' claims upon limited common resources with others' equally legitimate claims. (shrink)

Cost‐containment pressures impose fiscal responsibilities upon physicians that can conflict with their fiduciary commitment to patients. Should the law permit health care providers to adjust standards of care according to patients' financial resources? The legal concept of “rebuttable presumption” should be used to reconceive the traditional requirement of a uniform standard of care.

Critics sometimes claim that Catholic moral principles unreasonably oblige patients to adopt life-preserving medical treatments “at all costs,” even when the treatments are excessively burdensome or futile and when their adoption may badly disadvantage patients’ family members or caregivers. The author argues that this is a mischaracterization. Because of obligations arising from our relationships, not only is it sometimes licit to refuse lifesustaining medical care, but we sometimes have a duty to refuse it. This is the case when the treatments (...) are morally extraordinary and when adopting them would unfairly disadvantage someone for whom we have responsibility. The author argues that this conclusion is not inconsistent with the duty we have to properly care for our own lives or with moral principles prohibiting self-killing.

As the black clouds of war lift from the surface of the Continents of Europe and Nearer Asia, the eye looks round upon a shattered civilization. The once busy tide of labour on the field and in the factory, beneath the soil and within dock, ebbs slowly away; the accustomed rewards of toil, food, warmth and clothing, become daily more difficult of attainment. Authority trembles in its seat, and money loses its once all-powerful attraction. Inevitably the scholar recalls the tale (...) of the Decline and Fall of the Roman-Hellenistic world, and calculates the prospect of a second millennium of darkness and suffering. And he is not unconscious that he stands himself accused of having brought about, or at least failed to avert, the doom of the nations. For, he is told, the governing classes of all the nations that clashed in mutual destructiveness were constituted of men brought up in the classical tradition, whose minds in their fresh boyhood were fed on the so-called glories of Alexander the Great and of Julius Caesar, and who sought in rivalry to win, each for his nation, the haughty supremacy of imperial Rome. And he hears the clamour of those who demand a clean sweep of the false ideals and selfish ambitions of the past, and the building upon new foundations of a world of contentment and peace, inspired by the basic conception of a citizenship in which no man shall seek his own gain at the cost of another's loss. Towards the building up of this new world, it is claimed, the study of the past can do nothing to help; by effacing itself it will cease to be a hindrance. And in response to this accusation there arise in all directions schemes for a reconstructed world, a reconstituted nation, and a new education, which shall be alike in this one point—that they take for granted the elimination of the study of antiquity and the disappearance of the atmosphere of the Humanities.

Despite the fact that ethics consultations are an accepted practice in most healthcare organizations, many clinical ethicists continue to feel marginalized by their institutions. They are often not paid for their time, their programs often have no budget, and institutional leaders are frequently unaware of their activities. One consequence has been their search for concrete ways to evaluate their work in order to prove the importance of their activities to their institutions through demonstrating their efficiency and effectiveness.

In QALY-thinking, an activity that takes N people from a bad state (including 'dying') to the state of healthy for X years should have priority over an activity that takes N other people from the same bad state to a state of moderate illness for the same number of years (given equal costs). An empirical study indicates that this view may not be shared by the general public in Norway. Subjects tended to emphasise equality in value of life and in (...) entitlement to treatment rather than level of health after treatment. The relevance of costs per QALY in prioritising between different health care programmes in Norway is thereby brought in to doubt. While the sample in the study is too small to support firm policy conclusions, the results should contribute to an increased interest among health economists in actually measuring people's ethical preferences in matters of prioritising, rather than taking it for granted that their own values are shared by the general public.

It is difficult to reconcile claims about the Father's role as the progenitor of Trinitarian Persons with commitment to the equality of the persons, a problem that is especially acute for Social Trinitarians. I propose a metatheological account of the doctrine of the Trinity that facilitates the reconciliation of these two claims. On the proposed account, ‘Father’ is systematically ambiguous. Within economic contexts, those which characterize God's relation to the world, ‘Father’ refers to the First Person of the Trinity; within (...) theological contexts, which purport to describe intra-Trinitarian relations, it refers to the Trinity in toto-thus in holding that the Son and Holy Spirit proceed from the Father we affirm that the Trinity is the source and unifying principle of Trinitarian Persons. While this account is solves a nagging problem for Social Trinitarians it is theologically minimalist to the extent that it is compatible with both Social Trinitarianism and Latin Trinitarianism, and with heterodox Modalist and Tri-theist doctrines as well. Its only theological cost is incompatibility with the Filioque Clause, the doctrine that the Holy Spirit proceeds from both the Father and the Son—and arguably that may be a benefit. (shrink)

In this response, we address eight issues concerning our proposal that human minds contain adaptations for revenge and forgiveness.

The Federalist, justifying the Electoral College to elect the president, claimed that a small group of more informed individuals would make a better decision than the general mass. But the Condorcet Jury Theorem tells us that the more independent, better-than-random voters there are, the more likely it will be that the majority among them will be correct. The question thus arises as to how much better, on average, members of the smaller group would have to be to compensate for the (...) epistemic costs of making decisions on the basis of that many fewer votes. This question is explored in the contexts of referendum democracy, delegate-style representative democracy, and trustee-style representative democracy. (shrink)

This article proposes a geostatistical solution for area-to-point spatial prediction (downscaling) taking into account boundary effects. Such effects are often poorly considered in downscaling, even though they often have significant impact on the results. The geostatistical approach proposed in this article considers two types of boundary conditions (BC), that is, a Dirichlet-type condition and a Neumann-type condition, while satisfying several critical issues in downscaling: the coherence of predictions, the explicit consideration of support differences, and the assessment of uncertainty regarding the (...) point predictions. An updating algorithm is used to reduce the computational cost of area-to-point prediction under a given BC. In a case study, area-to-point prediction under a Dirichlet-type BC and a Neumann-type BC is illustrated using simulated data, and the resulting predictions and error variances are compared with those obtained without considering such conditions.

Changes in global patterns of grain production have affected the profitability of commercial, cash-crop agriculture in North America. The current financial crisis has highlighted a perceived conflict between the priorities of (1) strengthening net farm profit, (2) maintaining the productive potential of the land base, (3) enhancing the health and cohesiveness of the agricultural community, and (4) addressing societal demands for safe foodstuffs. Reducing input costs by reducing the need for privately owned machinery can minimize the scale-dependence of agricultural practices, (...) as illustrated with examples involving silage and intensively managed pasture in Ontario. This approach could improve farming opportunities for nontraditional, part-time farmers, and at the same time, create a niche for professional custom operators and managers. Enhancing the viability of nontraditional farm operations, a historically neglected component of the farming community, as well as commercial farms is viewed as one approach to sustaining and improving both the agricultural land base and the agricultural community. Applying resource-extensive rather than resource-intensive approaches to forage management reveals that these apparently divergent priorities are, in fact, interlocking pieces of the same puzzle.

It is standardly assumed that there are three — and only three — ways to solve problem of temporary intrinsics: (a) embrace presentism, (b) relativize property possession to times, or (c) accept the doctrine of temporal parts. The first two solutions are favoured by endurantists, whereas the third is the perdurantist solution of choice. In this paper, I argue that there is a further type of solution available to endurantists, one that not only avoids the usual costs, but is structurally (...) identical to the temporal-parts solution preferred by perdurantists. In addition to providing a general characterization of this new type of solution, I discuss certain of its anticipations in the literature on bundle theory, as well as provide a detailed development of it in terms of my own preferred metaphysics of ordinary objects — namely, a distinctive form of substratum theory tracing to Aristotle.

There has been much discussion of changing agricultural structure in the United States. In this paper, the author reviews some of the factors contributing to structural change in the United States and describes the policies adopted by the European Community with respect to agricultural structure. The European experience with structural policies suggests that this approach is not very promising for the United States where no specific structural policies exist. The argument developed in this paper is that structural changes in agriculture (...) are simply one example of economic adjustment in a capitalist economy, that economic adjustments are generally desirable although they are not costless, and that discussions of agricultural structure should focus on methods to alleviate the costs of adjustment rather than on efforts to prevent change.

How can health plans make fair determinations about when “experimental” (and costly) treatments such as high dose chemotherapy with autologous bone marrow transplantation should be covered despite lack of clear clinical consensus about their benefits? Different models for managing “last chance” therapies evolving in some health plans offer promising examples of how issues of fairness and legitimacy in decisionmaking can be addressed.

Confronted with mounting pressure to ensure accountability vis-à-vis customers, citizens and beneficiaries, organizational leaders need to decide how to choose and implement so-called accountability standards. Yet while looking for an appropriate standard, they often base their decisions on cost-benefit calculations, thus neglecting other important spheres of influence pertaining to more broadly defined stakeholder interests. We argue in this paper that, as a part of the strategic decision for a certain standard, management needs to identify and act according to the needs (...) of all stakeholders. We contend that the creation of a dialogical understanding among affected stakeholders cannot be a mere outcome of applying certain accountability standards, but rather must be a necessary precondition for their use. This requires a stakeholder dialogue prior to making a choice. We outline such a discursive decision framework for accountability standards based on the Habermasian concept of communicative action and, in the final section, apply our conceptual framework to one of the most prominent accountability tools (AA 1000).

Universal access to health care is still a dream rather than a reality in the United States. This is partly because a rule of rescue, by impelling us to help people in need, urges us to ignore the limits of our health care policies wherever those limits would adversely affect a given individual. As the rule of rescue undermines whatever limits we set on health care entitlements, it can thwart the cost containment so essential to expanding access. Rather than accept (...) unlimited expense, we have thus far declined to universalize health care. The situation is exacerbated by an economic insulation shielding patients and physicians from the costs of care, prompting both to regard health care as free, an unlimited right. To reverse this costly entitlement mentality and place reasonable limits on rescue, patients must exercise greater personal responsibility for the costs of their care by directly experiencing some of the economic consequences of their health care decisions. Several mechanisms are available to accomplish this goal without posing economic barriers to needed care or penalizing people for becoming ill.

Organizations are increasingly embedded with consultants and other non-employees who have the opportunity to engage in wrongdoing. However, research exploring the reporting intentions of employees regarding the discovery of wrongdoing by consultants is scant. It is important to examine reporting intentions in this setting given the enhanced presence of consultants in organizations and the fact that wrongdoing by consultants changes a key characteristic of the wrongdoing. Using an experimental approach, the current paper reports the results of a study examining employees' (...) reporting intentions subsequent to their discovery of wrongdoing by a consultant. The results of the study indicate that perceptions about the seriousness of a wrongdoing, personal costs and personal responsibility related to reporting a wrongdoing, and moral-equity judgments are significantly associated with reporting intentions for a normal reporting channel. Only perceptions of seriousness and personal costs are significantly associated for an anonymous reporting channel. Lastly, while personal costs for the anonymous reporting channel were lower than the normal reporting channel, reporting intentions were similar across the two channels. (shrink)

In 2008 New Zealand's pharmaceutical management agency, PHARMAC, made its final decision on the funding of trastuzumab (Herceptin) for HER2-positive early stage breast cancer. PHARMAC declined to fund the 12-month Herceptin regimen requested by the drug's manufacturer, funding instead a 9-week treatment regimen. The decision was justified on the grounds that there was insufficient evidence of additional long-term health benefits from the longer treatment course, which, coupled with the high cost of the drug, did not make the 12-month regimen sufficiently (...) cost-effective. This paper examines the criticism of PHARMAC's decision that ultimately led to the government's decision to expand the health budget in order to fund the 12-month regimen. It defends PHARMAC's decision against the charge of unfairness, arguing that for high-cost drugs with limited proven effectiveness it is not unfair to deny funding on grounds of cost-effectiveness, since although some moral priority must be given to helping those with serious diseases like breast cancer, the capacity of such drugs to swamp health care budgets is itself a significant moral issue. It concludes that the decision to expand the health budget to pay for Herceptin exacerbates rather than solves the political and moral problems involved in prioritizing health care resources.

Tort and contract law have not kept pace with the stunning changes in medicine's economics. Physicians are still expected to deliver the same standard of care to everyone, regardless whether it is paid for. Health plans increasingly face liability for unfortunate outcomes, even those stemming from society's mandate to keep costs down while improving population health. This book sorts through the chaos. After reviewing the inadequacies of current tort and contract law, Morreim proposes that an intelligent assignment of legal liability (...) must rest on an intelligent division of labor between health plans and providers, beginning with the question "who should be doing what, for the best delivery of health care." She also provides a comprehensive reference source of case law, commentary, and empirical literature. (shrink)

The Common Agricultural Policy (CAP) of the European Community (EC) has been criticized for causing a misallocation of resources, inequitable income transfers, and enormous budgetary costs. The purpose of this paper is to examine the political economy of agriculture and agricultural policy in the EC. The results of the analysis indicate that conflicts between national political objectives and broader, community-wide concerns are important factors in the performance of EC agriculture. The pressures for reform of the CAP will lead to modification (...) of the system, but changes in EC agricultural policy are likely to be moderate because of the inherent inertia of the policy-making process. As a result, the agricultural system in the EC will probably continue to evolve in an atmosphere of crisis with most reforms directed at symptoms rather than fundamental problems. (shrink)

A critique of conversational epistemic contextualism focusing initially on why pragmatic encroachment for knowledge is to be avoided. The data for pragmatic encroachment by way of greater costs of error and the complementary means to raise standards of introducing counter-possibilities are argued to be accountable for by prudence, fallibility and pragmatics. This theme is sharpened by a contrast in recommendations: holding a number of factors constant, when allegedly higher standards for knowing hold, invariantists still recommend assertion (action), while contextualists do (...) not. Given the knowledge norm of assertion, if one recommendation is preferable to the other, the result favors the preferred recommendation's account of knowledge. In the final section, I offer a unification of these criticisms centering on the contextualist use of 'epistemic position'. Their use imposes on threshold notions of justification, warrant, or knowledge tests that are suitable only to unlimited comparative or scalar notions like confidence or certainty and places them at one with an important strand of sceptical reasoning.

Suppose that you prefer A to B, B to C, and C to A. Your preferences violate Expected Utility Theory by being cyclic. Money-pump arguments offer a way to show that such violations are irrational. Suppose that you start with A. Then you should be willing to trade A for C and then C for B. But then, once you have B, you are offered a trade back to A for a small cost. Since you prefer A to B, you (...) pay the small sum to trade from B to A. But now you have been turned into a money pump. You are back to the alternative you started with but with less money. This Element shows how each of the axioms of Expected Utility Theory can be defended by money-pump arguments of this kind. The Element also defends money-pump arguments from the standard objections to this kind of approach. This title is also available as Open Access on Cambridge Core. (shrink)

Within Piaget there is an implicit theory of the development of explicit memory. It rests in the dynamical trajectory underlying the development of causality, object, space and time – a complex (COST) supporting a symbolic relationship integral to the explicit. Cassirer noted the same dependency in the phenomena of aphasias, insisting that a symbolic function is being undermined in these deficits. This is particularly critical given the reassessment of Piaget’s stages as the natural bifurcations of a self-organizing dynamic system. The (...) elements of a theoretical framework required to support explicit memory are developed, to include, (1) the complex developmental trajectory supporting the emergence of the explicit in Piaget, (2) the concrete dynamical system and the concept of a non-differentiable time contained in Bergson’s theory required to support a conscious, as opposed to an implicit remembrance, (3) the relation to current theories of amnesia, difficulties posed by certain retrograde amnesic phenomena, the role of the hippocampus and limitations of connectionist models, (4) the fact that nowhere in this overall framework does the loss of explicit memory imply or require the destruction of experience “stored in the brain.”.

This book brings together in one place the work of one of our most respected economic theorists, on a field in which he has played a large part in originating: the New Institutional Economics. Transaction cost economics, which studies the governance of contractual relations, is the branch of the New Institutional Economics with which Oliver Williamson is especially associated.Transaction cost economics takes issue with one of the fundamental building blocks in microeconomics: the theory of the firm. Whereas orthodox economics describes (...) the firm in technological terms, as a production function, transaction cost economics describes the firm in organizational terms, as a governance structure. Alternative feasible forms of organization--firms, markets, hybrids, bureaus--are examined comparatively. The analytical action resides in the details of transactions and the mechanisms of governance.Transaction cost economics has had a pervasive influence on current economic thought about how and why institutions function as they do, and it has become a practical framework for research in organizations by representatives of a variety of disciplines. Through a transaction cost analysis, The Mechanisms of Governance shows how and why simple contracts give way to complex contracts and internal organization as the hazards of contracting build up. That complicates the study of economic organization, but a richer and more relevant theory of organization is the result. Many testable implications and lessons for public policy accrue to this framework. Applications of both kinds are numerous and growing.Written by one of the leading economic theorists of our time, The Mechanisms of Governance is sure to be an important work for years to come. It will be of interest to scholars and students of economics, organization, management, and law. (shrink)
