Long-Term Contracts and the Principal-Agent Problem

This paper examines the principal-agent problem within professional sports. Imperfect information between managers and players, as well as the guaranteed income a long-term contract provides, are predicted to provide players with the incentive to alter effort over the length of a contract – especially during the first year of a long-term contract. Regression analysis indicates that players’ performance levels decline during the first year of a long-term contract, suggesting that the effects of the principal-agent problem may outweigh competing effects. The study does not, however, suggest that players increase performance in the final year of a contract

Narrative Ethics and Vulnerability: Kristeva and Ricoeur on Interdependence

The character and extent of disabilities, especially cognitive disability, have posed significance problems for existing moral theories. Certain philosophers have even questioned the moral personhood of people with disabilities and have argued that people with profound cognitive impairments should not be granted the same moral status as those who are cognitively able-bodied. This paper proposes an alternative understanding of moral personhood as relational rather than individuated. This relational moral personhood finds its foundation in the clinical practice and psychoanalysis of Julia Kristeva and the hermeneutic narrative identity of Paul Ricoeur. One consequence of this relational personhood is a new understanding of moral status through narrative co-authorship rather than intellectual or social capacity. Another consequence is a refiguration of narrative identity as narrative interdependence.

Testimony, Memory and Solidarity across National Borders: Paul Ricœur and Transnational Feminism

In many ways, globalization created the problem of representation for feminist solidarity across the borders of the nation state. This problem is one of presenting a cohesive identity for representation in the transnational public sphere. This paper proposes a solution to this problem of a cohesive identity for women’s representation by drawing on the work of Paul Ricœur. What these women seem to have in common are shared political aims, but they have no basis for those aims. This paper provides a basis for these aims by turning to Ricœur’s work on collective memory from Memory, History, Forgetting. The paper concludes that it is the shared testimony through narrative hospitality, which can provide a foundation for a social bond for those with common political aims. More specifically, this common knowledge provides a justification for the representation of women and their allies in the transnational public sphere.De différentes manières, la globalisation a créé un problème de représentation pour la solidarité féministe au-delà des frontières de l’Etat-nation. Ce problème consiste à présenter une identité cohérente en vue d’une représentation dans la sphère publique transnationale. Cet article propose une solution à ce problème de la constitution d’une identité cohérente pour la représentation des femmes en s’appuyant sur l’œuvre de Paul Ricœur. Ce que ces femmes semblent avoir en commun, ce sont des objectifs politiques partagés, mais elles ne disposent pas de bases pour ces objectifs. Cet article fournit une base à ces objectifs en faisant appel au travail de Ricœur sur la mémoire collective développé dans La Mémoire, l’histoire, l’oubli. L’article conclut que c’est le témoignage partagé à travers l’hospitalité narrative qui peut contribuer à fonder un lien social pour ceux qui ont des objectifs politiques communs. Plus spécifiquement, cette connaissance commune fournit une justification à la représentation des femmes et de leurs alliés dans la sphère publique transnationale

Prediction of risk of fracture in the tibia due to altered bone mineral density distribution resulting from disuse : a finite element study

The disuse-related bone loss that results from immobilisation following injury shares characteristics with osteoporosis in postmenopausal women and the aged, with decreases in bone mineral density (BMD) leading to weakening of the bone and increased risk of fracture. The aim of the study was to use the finite element method to: (i) calculate the mechanical response of the tibia under mechanical load and (ii) estimate the risk of fracture; comparing between two groups, an able bodied (AB) group and spinal cord injury (SCI) patients group suffering from varying degree of bone loss. The tibiae of eight male subjects with chronic SCI and those of four able-bodied (AB) age-matched controls were scanned using multi-slice peripheral Quantitative Computed Tomography. Images were used to develop full three-dimensional models of the tibiae in Mimics (Materialise) and exported into Abaqus (Simulia) for calculation of stress distribution and fracture risk in response to specified loading conditions – compression, bending and torsion. The percentage of elements that exceeded a calculated value of the ultimate stress provided an estimate of the risk of fracture for each subject, which differed between SCI subjects and their controls. The differences in BMD distribution along the tibia in different subjects resulted in different regions of the bone being at high risk of fracture under set loading conditions, illustrating the benefit of creating individual material distribution models. A predictive tool can be developed based on these models, to enable clinicians to estimate the amount of loading that can be safely allowed onto the skeletal frame of individual patients who suffer from extensive musculoskeletal degeneration (including SCI, multiple sclerosis and the ageing population). The ultimate aim would be to reduce fracture occurrence in these vulnerable groups

In vivo stability and biocompatibility of implanted calcium alginate disks

Alginate is a commonly used biomedical hydrogel whose in vivo degradation behavior is only beginning to be understood. The use of alginate in the central nervous system is gaining popularity as an electrode coating, cell encapsulation matrix, and for duraplasty. However, it is necessary to understand how the hydrogel will behave in vivo to aid in the development of alginate for use as a neural interface material. The goal of the current study was to compare the rheological behavior of explanted alginate disks and the inflammatory response to subcutaneously implanted alginate hydrogels over a 3-month period. Specifically, the effects due to (1) in situ gelling, (2) diffusion gelling, and (3) use of a poly- l -lysine (PLL) coating were investigated. While all samples' complex moduli decreased 80% in the first day, in situ gelled alginate was more stable for the first week of implantation. The PLL coating offered some stability increases for diffusion gelled alginate, but the stability in both conditions remained significantly lower than that in in situ gelled alginate. There were no differences in biocompatibility that clearly suggested one gelation method over another. These results indicate that in situ gelation is the preferred method in neural interface applications where stability is the primary concern. © 2007 Wiley Periodicals, Inc.

Flourishing Bodies: Disability, Virtue, Happiness

Thesis advisor: Richard KearneyThe pursuit of living a good and moral life has been a longstanding ideal of philosophy, an ideal that dates back to the writings of Plato, and more specifically, Aristotle. This ideal establishes that a good life as a happy and flourishing life is pursued by developing the right motives and the right character. And in order to live this life, one must, then, develop a virtuous character, i.e., be a virtuous person, who desires the good. Finally, in the pursuit of the good, one must not do so alone; rather, one should pursue the virtuous life with others, i.e., friends, because they enhance our ability to think and to act. This specific position which is taken up by Aristotelian virtue ethics, however, has recently come under scrutiny by certain studies in social psychology. Particularly, the concept of character has been discredited by empirical studies. Furthermore, the classic model of the virtuous person has assumed only persons with able-bodies. As a result of these two criticisms, Aristotelian virtue ethics has been discredited as a fantasy ethics available for only a few to achieve. The principle aim of this dissertation is to develop and defend an account of Aristotelian virtue ethics which is grounded in empirical psychology and enables people with disabilities to flourish as moral exemplars within a society. The value of virtue and character for ethical debate is imperative for human happiness within moral life. Instead of happiness being something an individual strives to acquire or feel, Aristotelian virtue ethicists have argued that true happiness is human flourishing. In other words, in order to be happy, humans should focus not just on what it is good to do, but also, and more importantly, focus on who it is good to be. To live a good life, then, it is necessary that one is a good person, or has a good character. Thus, to acquire virtues such as charity, benevolence, honesty, and generosity and to shun vices such as dishonesty, cruelty, or stinginess, is the task, Aristotelian virtue ethicists have argued, that leads to eudaimonia, i.e., human flourishing. The person who has acquired virtuous character traits, then, is the person who is most happy in life. However, the attempt to understand human happiness as a result of a virtuous character has become vulnerable to criticism from philosophical positions grounded in empirical psychology and disability theory. In light of the charge that virtue ethics is a fantasy ethics, many philosophers argue that Aristotelian virtue ethics should be abandoned because it is an ethics with little or no scientific basis. In my defense of Aristotelian virtue ethics, I first address the objection that Aristotelian virtue ethics is a "fantasy ethics" which has no grounding in empirical psychology, and thus, as a result, should not be used for moral theory. This objection has been put forth by certain "Situationist" philosophers, who cite psychological studies which demonstrate that the idea of a virtue as a "global character trait" is something that humans do not actually, or very rarely, possess. This objection to Aristotelian virtue ethics has dealt a devastating blow. In response to this objection, philosopher Nancy Snow has mounted a defense of Aristotelian virtue ethics which is grounded in empirical psychology. Snow's defense, though superficially appealing, has two intractable problems. I address the failure of her proposal in Chapter One: The Problem of Virtue as Social Intelligence. The first problem Snow faces concerns her use of CAPS as a method for virtue ethics to be used throughout life. I call this problem the longitudinality problem, which argues that Snow's proposal for the constancy of virtue for longer than a period of six weeks is overreaching. The second problem Snow faces concerns her reliance on virtue as social intelligence for the actual achievement of being virtuous in daily living. This problem turns on the empirical criteria for what makes a person capable of virtuous action and I call this problem the exclusivity problem, which excludes people with "Autism" form being virtuous. As an alternative to Snow's account, I begin my defense of Aristotelian virtue ethics by developing the following account of empirical virtue based on a narrative identity which desires and actively pursues the good in life-long striving. This moral desire is encouraged through the shared dialogue of virtuous caregiving, which enables a moral novice to flourish and grow into a moral expert. This pursuit of the good enables everyone to flourish and incorporates insights from disability, embodied cognition and social psychology. To accomplish this task, I begin with an examination of the first of two foundational components of character, i.e., the four processing levels of CAPS theory in Chapter Two: Moral Perception. Although CAPS theory provides a solid beginning for an account of virtue, it is not a sustainable theory throughout life. This theory of social-cognitive moral psychology needs to be supplemented by developmental moral psychology. CAPS theory also assumes the individual's perspective in the dynamic interaction between situation and character. It assumes a person's intentions, and this assumption of intentionality - desires, intentions, and beliefs - assumes a person's embodiment in that situation. In other words, CAPS theory assumes lived embodiment. In this chapter, I turn to the method of phenomenology used by both psychologists and philosophers of embodied cognition to account for the moral "interpretation of the situation" experienced by people with illness or impairment. As a complimentary to CAPS and the second foundational component for character, certain moral psychologists have argued for the narrative development of Event Representations for virtuous character. This development begins with the shared dialogue of the caregiver and dependent asking the dependent to recall events which have just occurred. In this practice, the caregiver's aim is to help the dependent form memories and incorporate those memories into the creation of a narrative identity. In Chapter Three: Representations of Moral Events, I extend the caring relation to this practice of shared dialogue to incorporate certain forms of intellectual disability, such as "Autism" and Alzheimer's disease. To accomplish this, I incorporate the roles of narrative and trust in order to construct the relation of dependency and interdependency as trusting co-authorship rather than reciprocal capability. After establishing the importance of the caregiver in the development of one's narrative identity, I employ the life narrative longitudinal psychological approach to moral development as a structure for the moral event representations and schemas guided by the caregiver. Finally, I argue that the co-authorship of one's life story animates one's moral desire for the good and as a result, leads to the development of interdependent virtues. In Chapter Four: Moral Self-Coherence through Personal Strivings, I examine the importance of personal strivings for a sense of lived self-coherence for character over time. My argument is that our personal strivings are unified by the life story which animates and directs those strivings throughout our lives. Although our personal strivings may be altered or deterred due to life transitions including accident, illness, and "disabling injury," they still retain a sense of unity through our overarching life story. It is this narrative which gives unity to both our psychological intentions and bodily intentions, even when they are experienced as a phenomenally lived dualism due to illness, stroke, or impairment. In order to make my argument, I examine ten case studies from medical patients. I argue that our personal strivings toward the good guide our growth of character from a moral novice to become a moral expert. In Chapter Five: Flourishing Bodies, I develop an empirically grounded model of a virtuous character which begins with interdependent virtues and eventually grows into independent virtues. To do this, I draw on the two foundational components of character: CAPS theory and event representations. From the caring relation and shared dialogue of the caregiver, an individual begins to develop basic moral schemas, tasks, and scripts. This is when the individual is a moral novice. As the novice pursues excellences in these practices, the novice grows into a moral expert according to those virtues and becomes virtuously independent. The moral expert, unlike the moral novice, executes virtuous action with ease. Having acquired skills of virtue and knowledge, the moral expert knows the right thing to do at the right time and does so with the right reasons. MacIntyre, however, acknowledged the limit of ethics and turned to politics to address specific needs for people with disabilities such as care, financial support, educational support, and political proxy. The purpose of the final chapter, The Virtue-Oriented Politics of Interdependence, is to follow MacIntyre's endeavor and to propose a virtue-oriented politics of interdependence as an initial solution. First, I examine the various forms of oppression facing people with disabilities in society. In order to address these forms of oppression for people with disabilities, I argue that a shift in the central component of a political framework is needed. Instead of focusing on distribution or recognition, one should focus on education in the broad sense. In conclusion of my dissertation, The Fragility of Virtue, I provide a perspective of our human condition that is a vulnerable one. In this final section, I discuss the role of our collective vulnerability and the fragility of human goodness with regard to illness and impairment. And that our interdependence is strengthened through the virtue of friendship. I finish with a proposal of the role of sacrifice as a way to reconcile the pursuit of a flourishing life in the face of our own fragility.Thesis (PhD) — Boston College, 2013.Submitted to: Boston College.

Foraging theory provides a useful framework for livestock predation management

A societal shift toward plant dominant diets and a reduction in livestock rearing could have broad social, environmental and conservation benefits. Livestock husbandry, however, has a wealthy cultural history, strong support and high consumer demand. It is therefore likely to continue as a major land use and conservation issue for predators. From a producer’s perspective, the primary goals of livestock protection are maximising, or at least maintaining, production by minimising losses and mitigating detriment to stock welfare. Lethal removal of predators remains a commonplace solution. Such management measures are questionable as they raise animal welfare and conservation concerns, risk inhibiting ecological processes, are often expensive, and in some circumstances, exacerbate livestock predation problems. Non-lethal alternatives can facilitate co-existence between livestock farmers and predators, ideally reducing the ecological impact of pastoralism and achieving conservation goals. The need for rigorous study of non-lethal approaches has however been recently highlighted. Tools and methods involved in livestock protection, as well as the theoretical basis of how we perceive and manage the problem, require deeper consideration. Non-lethal approaches require knowledgeable implementation and an effective decision making system is a prerequisite for successful practice. Livestock predation and its prevention are fundamentally influenced by the underlying principles of foraging ecology and risk theory. We propose that manipulating elements of Brown’s (1988) quitting harvest rate model provides a useful conceptual framework for reducing livestock predation and encouraging coexistence.http://www.elsevier.de/jnc2020-06-01hj2019Centre for Wildlife Managemen
