The ethical considerations of insider trading have been widely debated in the academic literature :171–182, 1990). In 2013, the STOCK Act, which was initially passed to mitigate insider trading by government officials, was quickly and unexpectedly amended to allow certain government employees to withhold their financial information. To identify and quantify the potential costs placed on investors by non-corporate insider traders, we use the unusual circumstances surrounding this amendment. For a sample of stocks most held by members of Congress, we (...) find that, relative to control stocks, liquidity significantly worsens and volatility increases during the post-amendment period. Our results highlight the costs that are incurred by investors in the presence of non-corporate insider trading. These findings call for a stronger development of an ethical framework that justifies the restriction of all types of insider trading. (shrink)

The brain is an ever‐changing organ that encodes memories and directs behavior. Neuroanatomical studies have revealed structural plasticity of neural architecture, and advances in gene expression technology and epigenetics have demonstrated new mechanisms underlying the brain's dynamic nature. Stressful experiences challenge the plasticity of the brain, and prolonged exposure to environmental stress redefines the normative transcriptional profile of both neurons and glia, and can lead to the onset of mental illness. A more thorough understanding of normal and abnormal gene expression (...) is needed to define the diseased brain and improve current treatments for psychiatric disorders. The efforts to describe gene expression networks have been bolstered by microarray and RNA‐sequencing technologies. The heterogeneity of neural cell populations and their unique microenvironments, coupled with broad ranging interconnectivity, makes resolving this complexity exceedingly challenging and requires the combined efforts of single cell and systems level expression profiling to identify targets for therapeutic intervention.

Schnorr randomness is a notion of algorithmic randomness for real numbers closely related to Martin-Löf randomness. After its initial development in the 1970s the notion received considerably less attention than Martin-Löf randomness, but recently interest has increased in a range of randomness concepts. In this article, we explore the properties of Schnorr random reals, and in particular the c.e. Schnorr random reals. We show that there are c.e. reals that are Schnorr random but not Martin-Löf random, and provide a new (...) characterization of Schnorr random real numbers in terms of prefix-free machines. We prove that unlike Martin-Löf random c.e. reals, not all Schnorr random c.e. reals are Turing complete, though all are in high Turing degrees. We use the machine characterization to define a notion of "Schnorr reducibility" which allows us to calibrate the Schnorr complexity of reals. We define the class of "Schnorr trivial" reals, which are ones whose initial segment complexity is identical with the computable reals, and demonstrate that this class has non-computable members.

ABSTRACT:This manuscript develops the concept of organizational virtue orientation (OVO) and examines differences between family and non-family firms on the six organizational virtue dimensions of Integrity, Empathy, Warmth, Courage, Conscientiousness, and Zeal. Using content analysis of shareholder letters fromS&P 500companies, our analyses find that there are significant differences between family and non-family firms in their espoused OVO, with family firms generally being higher. Specifically, family firms were significantly higher on the dimensions of Empathy, Warmth, and Zeal, but lower on Courage. (...) Based on these findings we further develop the OVO concept through the discussion of implications and areas for future research. (shrink)

First published in 2000, this translation of one of the great works of Western political thought is based on the assumption that when Plato chose the dialogue form for his writing, he intended these dialogues to sound like conversations - although conversations of a philosophical sort. In addition to a vivid, dignified and accurate rendition of Plato's text, the student and general reader will find many aids to comprehension in this volume: an introduction that assesses the cultural background to the (...) Republic, its place within political philosophy, and its general argument; succinct notes in the body of the text; an analytical summary of the work's content; a full glossary of proper names; a chronology of important events; and a guide to further reading. The result is an accomplished and accessible edition of this seminal work, suitable for philosophers and classicists as well as historians of political thought at all levels. (shrink)

This chapter focuses on changing moral values associated with the provision of public goods, which incorporates an additional moral condition based on donor self-interest. Assistance for less-developed countries to replace ozone-depleting chlorofluorocarbons with non-ozone-depleting hydrofluorocarbons helps the donor country to achieve a thicker stratospheric ozone layer, which protects its own citizens, along with others. The elimination of corrupt practices can provide LDCs with markets for primary exports and lead to better provision of public goods. Improved economic conditions in these countries (...) through different economic and humanitarian measures can improve the prospects of secondary public goods sectors. Aggregator technologies can also play a key role in public goods assistance, with greater implications for the donor and recipient countries. (shrink)

Psychophysical studies of change blindness indicate that, at any instant, human observers are aware of detail in few parts of the visual field. Such results suggest, to some theorists, that human vision reconstructs only a few portions of the visual scene and that, to bridge the resulting representational gaps, it often lets physical objects serve as their own short-term memory. We propose that human vision reconstructs no portion of the visual scene, and that it never lets physical objects serve as (...) their own short-term memory. (shrink)

This book re-examines aspects of historical socialism, and includes case studies of education within twenty-first century socialist and post-socialist contexts shaped by the trajectories of historical socialism. Through these case studies, contributions offer insights into key questions: How are education systems and student subjectivities shaped by post-socialist trajectories and current regional politics, economics and resistance movements? How do sedimented socialist discourses and geographies alter and contest the ‘neoliberal child’ and ‘childhood’ in post-socialist education? How have disjunctures between the rhetoric of (...) historical Marxism-Leninism and the practices of educators, students and student political organizations played out under socialism, and what could we learn from that for our present? How much emancipatory potential is there in the theories and practices of education for combatting injustice in the absence of mass, revolutionary political parties? Above all, this volume affirms the need to move beyond simplistic accounts of historical socialism and post-socialist transitions. By exploring how socialist trajectories remain influential and have potential in our current contexts, this book contributes to the work of politically engaged educators working to re-imagine and reconstruct education. This book was originally published as a special issue of _Globalisation, Societies and Education. _. (shrink)

It is gratifying to read, in a recent issue of this periodical, Mr. A. A. Barrett's informed exposition of the syntax of this passage, even though he balks at the need to extract a grammatical subject for the verb deducit in 157 from the relative pronoun qua in the previous line. However his persuasive presentation of what he relies on as evidence in support of his suggested interpretation from the mosaics from Zliten in Tripolitania, which portray scenes in an amphitheatre, (...) may seduce the unwary into an over-ready acquiescence in his proposal to read raeda in 157 for taeda of the manuscript tradition. Juvenal's words were correctly understood by T. Maguire as long ago as 1881, and the solution was restated with clarity in a note by W. V. Clausen recently. (shrink)

Pope John Paul II called for an intense dialogue between science and theology, “a common interactive relationship,” in which each discipline is “open to the discoveries and insights of the other” while retaining its own integrity. This essay seeks to be responsive to that call and is an initial exploration of relationships between contemporary neuroscience and Catholic theological ethics. It examines neuroscientific data on the bicameral brain and theological ethical data on marital ethics, including divorce and remarriage, and asks what (...) insight the former might provide into both the latter and the different ethical methods that respond to marital ethics. The analysis is undertaken in the hope of illuminating a pathway that opens the insights of one way of doing theological ethics to the insights of another way, thereby eliminating the unnecessary, unhelpful, and sometimes un‐Christian polarizations that presently separate them.

The distribution of parts between the available actors in ancient comedy has frequently engaged critical attention, but it has only recently become possible to test the principles believed to be at work against a play of Menander which is for practical purposes preserved complete. The present inquiry will suggest that either four principal actors are needed or, alternatively, that three actors can carry the major roles between them, provided that the part of Getas is split between two of them and (...) that a supernumerary actor is available for two small parts, together with parachoregemata in a few places and a kophon prosopon twice. It is not easy to choose between these two possibilities, but there may be sufficient hints in the dramatic economy of the play to warrant preference for the three-actor alternative. (shrink)

This essay, which is the editor's introduction to part 1 of a multipart symposium on quietism, also constitutes his call for symposium papers. The symposium is meant be comprehensive. It is described as political and broadly cultural as well as religious, and in religious terms is said to cover not only the Catholic and Protestant quietisms (most properly so called) of the late seventeenth and eighteenth centuries, but also the proto-quietisms of the medieval Western church and reputedly quietist aspects of (...) the Gnostic, Eastern Orthodox, early Hasidic, Shi'ite, Jain and other Indic, Taoist, and Zen religious traditions. This introduction emphasizes the secular approaches, mostly antipolitical or postphilosophical, that wear the adjective “quietist” metaphorically, including the postmodern currents that Martha Nussbaum has named “hip quietism” and the “minimalist” philosophical version developed by Wittgenstein and some of his successors, notably Richard Rorty. This introduction concludes with attention to Rorty's late essay “Naturalism and Quietism,” then with a dedication of the entire symposium to Rorty's memory. (shrink)

The truth about line 70 was public property as far back as Plathner, who is quoted by Ruperti, but modern editors shy away from it and, with a perverse unanimity, print the accusative rubetam. Not only must viro then be taken with sitiente as an ablative absolute, in spite of the proximity of porrectura, but there is no internal coherence in the relative clause. R. Beer put his finger on the nerve of the matter: ‘possumus quidem miscere vinum, miscere venenum, (...) sed si mulier vinum porrigit interea venenum miscet, non vino immiscet, nihil inest periculi viro.’ All is resolved once the proper force of sitiente is recognized: it qualifies rubeta and means sitim faciente, ‘parching’.
