A scholarly study of the Neoplatonic philosopher Plotinus (204/5-270) and his understanding of the soul; its chapters include: beauty and the good, forgetting the self, matter as indefinite and incorporeal, omnipresence and incorporeality, and omnipresence and transcendence. The work confirms much recent scholarly consensus on Plotinus, but many of the author's interpretations and general conclusions also give constructive challenges to some existing modes of understanding Plotinus's thought. The arguments and their textual evidence, with the accompanying Greek, provide the reader with (...) direct evidence for testing these conclusions as well as appreciating the nature of Plotinus' philosophizing.

Prior research suggests that voluntary environmental governance mechanisms operate to enhance a firm’s environmental legitimacy as opposed to being a driver of proactive environmental performance activities. To understand how these mechanisms contribute to the firm’s environmental legitimacy, we investigate whether environmental corporate governance characteristics are associated with voluntary environmental disclosure. We examine an increasingly important attribute of a firm’s disclosure setting, namely the disclosure of greenhouse gas (GHG) information. GHG information represents proprietary non-financial information about the firm’s exposure to environmental (...) concerns and is related to the firm’s operations and future profitability. Thus, we expect governance participants would view such information as a potentially important strategic device for managing stakeholders’ demands for information concerning environmental risks. We find that the presence of an environmental committee and a Chief Sustainability Officer (CSO) is positively associated with the likelihood of GHG disclosure and that CSOs are associated with disclosure transparency. Further analysis reveals that the likelihood of disclosure is associated with committee size, number of committee meetings, expertise of committee members and CSO, and overlap between the environmental committee and audit committee. Only expertise of the environmental committee members and the CSO are associated with GHG disclosure transparency, while larger committees tend to be associated with lower transparency. Our results are particularly important to those with interests in evaluating the potential role that corporate governance mechanisms play in responding to stakeholder concerns about environmental risks. Directors and officers who are considering appointment to similar governance positions, may wish to consider what attributes would make such governance positions more influential. (shrink)

The creation of a specialized executive position that oversees sustainability activities represents a distinct shift in the structure of top management teams and their approach for addressing sustainability concerns. However, little is known about these management team members, namely the corporate sustainability officers or CSOs. We examine CSO appointments and their association with subsequent sustainability performance. Our results indicate that the creation of a CSO position may represent more of a symbolic versus substantive governance mechanism. Further tests suggest that CSO (...) expertise and the firm’s existing sustainability performance affect the association between the CSO and post-appointment sustainability performance. We find no association between CSO appointments and subsequent sustainability performance for firms that were already poor performers, while firms possessing relatively higher levels of prior sustainability performance appointing a CSO begin to experience significant improvements to performance after 3 years. We further find that CSOs with prior sustainability expertise are associated with increases in sustainability performance in firms that were already strong performers, but not in firms with poor sustainability performance. Non-expert CSOs, on the other hand, are associated with initial decreases in performance for poor performing firms, whereas better performing firms hiring non-expert CSOs are able to rely on other sustainability attributes of the firm and benefit from improvements in performance in the long term. We discuss the potential importance of these positions as it relates to symbolic versus substantive governance mechanisms through the lens of top management team literature streams. (shrink)

Theories of language production have long been expressed as connectionist models. We outline the issues and challenges that must be addressed by connectionist models of lexical access and grammatical encoding, and review three recent models. The models illustrate the value of an interactive activation approach to lexical access in production, the need for sequential output in both phonological and grammatical encoding, and the potential for accounting for structural effects on errors and structural priming from learning.

Health care is transitioning from genetics to genomics, in which single-gene testing for diagnosis is being replaced by multi-gene panels, genome-wide sequencing, and other multi-genic tests for disease diagnosis, prediction, prognosis, and treatment. This health care transition is spurring a new set of increased or novel liability risks for health care providers and test laboratories. This article describes this transition in both medical care and liability, and addresses 11 areas of potential increased or novel liability risk, offering recommendations to both (...) health care and legal actors to address and manage those liability risks.

Management plays an important role in reinforcing ethics in organizations. To support this aim, managers must use incentive and goal programs in ethical ways. This study examines experimentally the potential ethical costs associated with incentive-driven and goal-induced employee behavior from a managerial perspective. In a quasi-experimental setting, 243 MBA students with significant professional work experience evaluated a hypothetical employee’s ethical behavior under incentive pay systems modeled on a business case. In the role of the employee’s manager, participants evaluated the ethicality (...) of the employee’s incentive-driven and goal-induced ethical/unethical behavior and the outcomes of behavior, with consequences that were either favorable or unfavorable to the organization. The results indicated that participants discounted the ethical considerations of incentive-driven and goal-induced behavior when consequences were favorable to the organization. Participants’ morals and outcome orientations were also significantly related to their ethical judgments and intentions to intervene. The implications of these findings for research and practice are discussed. (shrink)

Volume XXIX contains papers and commentaries presented to the Boston Area Colloquium in Ancient Philosophy during academic year 2012-13. The papers feature Plato's Republic and Timaeus, examine Aristotle on generation, analogy and method, and analyze Proclus on first principles.

Pickering & Garrod (P&G) consider the possibility that inner speech might be a product of forward production models. Here I consider the idea of inner speech as a forward model in light of empirical work from the past few decades, concluding that, while forward models could contribute to it, inner speech nonetheless requires activity from the implementers.

Pictorial representation is one of the core questions in aesthetics and philosophy of art. What is a picture? How do pictures represent things? This collection of specially commissioned chapters examines the influential thesis that the core of pictorial representation is not resemblance but 'seeing-in', in particular as found in the work of Richard Wollheim. We can see a passing cloud _as_ a rabbit, but we also see a rabbit _in_ the clouds. 'Seeing-in' is an imaginative act of the kind employed (...) by Leonardo’s pupils when he told them to see what they could - for example, battle scenes - in a wall of cracked plaster. This collection examines the idea of 'seeing-in' as it appears primarily in the work of Wollheim but also its origins in the work of Wittgenstein. An international roster of contributors examine topics such as the contrast between seeing-in and seeing-as; whether or in what sense Wollheim can be thought of as borrowing from Wittgenstein; the idea that all perception is conceptual or propositional; the metaphor of figure and ground and its relation to the notion of 'two-foldedness'; the importance in art of emotion and the imagination. Wollheim, Wittgenstein and Pictorial Representation: Seeing-as and Seeing-in is essential reading for students and scholars of aesthetics and philosophy of art, and also of interest to those in related subjects such as philosophy of mind and art theory.

The sociobiology of bacteria, largely unappreciated and ignored by the microbiology research community two decades ago is now a major research area, catalyzed to a significant degree by studies of communication and cooperative behavior among the myxobacteria and in quorum sensing (QS) and biofilm formation by pseudomonads and other microbes. Recently, the topic of multicellular cooperative behaviors among bacteria has been increasingly considered in the context of evolutionary biology. Here we discuss the significance of two recent studies1,2 of the phenomenon (...) of “cheating” mutants and their exploitation of cooperating microbial populations of Pseudomonas aeruginosa.

Federal guidelines require that informed consent be obtained from participants when they are enrolled in a research study. When conducting research with children, the guidelines utilize the term permission to describe parents' agreement to enroll their children in a study. The basic components of consent and permission are well described and identical, with the exception of the person for whom the decision to participate is being made. Beyond permission, when enrolling minor participants in research, affirmative agreement to participate in research (...) or assent must be obtained from the child participants themselves. The concept of children's assent to research, however, is poorly defined, resulting in inconsistency in its pursuit and, consequently, in its utility. The interface between cognitive development, emotional, and social development must be examined as it pertains to this special situation of decision making. For this process to meaningfully protect minors, the assent process must be clarified, decisions regarding parental veto power must be more convincingly justified, and researchers must be better educated and held accountable for the valid execution of this process. Strategies for implementing the assent process more effectively are presented. (shrink)

Increasing working memory (WM) capacity is often cited as a major influence on children's development and yet WM capacity is difficult to examine independently of long‐term knowledge. A computational model of children's nonword repetition (NWR) performance is presented that independently manipulates long‐term knowledge and WM capacity to determine the relative contributions of each in explaining the developmental data. The simulations show that (a) both mechanisms independently cause the same overall developmental changes in NWR performance, (b) increase in long‐term knowledge provides (...) the better fit to the child data, and (c) varying both long‐term knowledge and WM capacity adds no significant gains over varying long‐term knowledge alone. Given that increases in long‐term knowledge must occur during development, the results indicate that increases in WM capacity may not be required to explain developmental differences. An increase in WM capacity should only be cited as a mechanism of developmental change when there are clear empirical reasons for doing so. (shrink)

We submit this brief in support of the Nonhuman Rights Project’s efforts to secure habeas corpus relief for the elephant named Happy. We reject arbitrary distinctions that deny adequate protections to other animals who share with protected humans relevantly similar vulnerabilities to harms and relevantly similar interests in avoiding such harms. We strongly urge this Court, in keeping with the best philosophical standards of rational judgment and ethical standards of justice, to recognize that, as a nonhuman person, Happy should be (...) released from her current confinement and transferred to an appropriate elephant sanctuary, pursuant to habeas corpus.

This paper uses the notion of Galois-connection to examine the relation between valuation-spaces and logics. Every valuation-space gives rise to a logic, and every logic gives rise to a valuation space, where the resulting pair of functions form a Galois-connection, and the composite functions are closure-operators. A valuation-space (resp., logic) is said to be complete precisely if it is Galois-closed. Two theorems are proven. A logic is complete if and only if it is reflexive and transitive. A valuation-space is complete (...) if and only if it is closed under formation of super-valuations. (shrink)

Whitehead's 1922 theory of gravitation continues to attract the attention of philosophers, despite evidence presented in 1971 that it violates experiment. We demonstrate that the theory strongly fails five quite different experimental tests, and conclude that, notwithstanding its meritorious philosophical underpinnings, Whitehead's theory is truly dead.

Genomic research projects that collect tissues from deceased organ and tissue donors must obtain the authorization of family decision makers under difficult circumstances that may affect the authorization process. Using a quasi-experimental design, the Ethical, Legal, and Social Issues (ELSI) substudy of the Genotype-Tissue Expression (GTEx) project compared the recall and understanding of the donation authorization process of two groups: family members who had authorized donation of tissues to the GTEx project (the comparison group) and family members who had authorized (...) organ and tissue donations in years previous, who subsequently participated in two different mock-authorization processes that mimicked the GTEx authorization process (the intervention groups). Participants in the comparison and intervention groups were matched on key demographic characteristics.We found that participants in the intervention groups who experienced a mock-authorization process demonstrated better recall of the tissue donation request than members of the comparison group. Our data indicate that the stress associated with the loss of a loved one limited the ability of family members to recall details about the GTEx project. However, we found a similar lack of knowledge in both the comparison and the intervention group participants, suggesting lack of knowledge may be due to the complexity and unfamiliarity of the information presented to them during the authorization process. We discuss these findings in the context of everyday clinical decision making in cognitively challenging conditions. (shrink)

The empirical diagnosis presented in this paper is based on interviews with nurse practitioners and physicians designed to elicit their perceptions of the nature and role of ethical dilemmas in clinical practice. Having selected five of these perceptions or views which were common and significant. the philosophical therapy offered consists in, first, a general discussion of ethical dilemmas, and second, a critical analysis of each of the five views with the aim of pointing out confusions and errors, the recognition of (...) which can be of applied and practical help in the clinical setting.
