The emergence of new biological traits is landmarks of evolutionary progress. However, when, how, and why do they appear? We propose a universal mechanism, a Buffering Mechanism of Evolution to understand these questions. We speculate that all organisms possess this potential buffer capacity. This capacity would be triggered by the pressures, natural or artificial, to express the intrinsic potential variants. The potential buffer capacity of the organism increases for further selections as evolutionary progress occurs. The higher the evolutionary level of (...) the organism, the greater the potential buffer capacity, and importantly, the buffer capacity versus the pressures of selections will result. However, when the pressures are far more than the potential capacity of the targets, the natural or artificial pressures then compromise the genetic buffering system resulting in possible species extinction if the emergence of new traits fails.

This study investigated the differences between past and future temporal discounting in terms of neural activity in relation to temporal distance. Results show that brain regions are engaged differently in past and future temporal discounting. This is likely because past temporal discounting requires memory reconstruction, whereas future temporal discounting requires the processing of uncertainty about the future. In past temporal discounting, neural activity differed only when preferences were made between rewards received one hour prior and rewards received further in the (...) past. The peak amplitudes of P2 and P3 varied as the temporal distance increased from 2 weeks to 50 years. In future temporal discounting, neural activity differed only when preferences were evaluated between two delayed rewards. The delay conditions and had a significant influence on P2 and N2. Findings indicate the existence of different decision-making systems operating in past and future temporal discounting. (shrink)

Whether or not a public relations code of ethics should be enforced, among others, has become one of the most widely controversial topics, especially after the Hill and Knowlton case in 1992. I take the position that ethical codes should be enforced and address this issue from eight aspects: (a) Is a code of ethics an absolute prerequisite of professionalism? (b) Should problems of rhetoric per se in a code of ethics become a rationale against code enforcement? (c) Is a (...) code of ethics of any significance? (d) Is the ethical code is enforceable, (e) Would the licensure system interfere with the freedom of expression of the practitioners? (f) Do PR practitioners choose to be ethical (if they do) because they have to be or because they want to be? (g) Would the public interest be virtually assured as a result of a public relations? and (h) Can education in ethics overcome the ethical problems in public relations? (shrink)

This article presents evidence supporting the claim that ethical reasoning is a skill that can be taught and assessed. We propose a working definition of ethical reasoning as 1) the ability to identify, analyze, and weigh moral aspects of a particular situation, and 2) to make decisions that are informed and warranted by the moral investigation. The evidence consists of a description of an ethical reasoning education program—Ethical Reasoning in Action —designed to increase ethical reasoning skills in a variety of (...) situations and areas of life. ERiA is housed at a public, major comprehensive U.S. university—James Madison University—and assessment of the program focuses on interventions delivered prior to and during orientation for incoming first-year students. Findings indicate that the interventions measurably enhance the ability of undergraduate students to reason ethically. ERiA’s competency-targeted program and positive student learning outcomes offers a promising model for higher education ethics programs seeking to connect classroom learning in ethics to decision-making in everyday life.

We investigate whether air pollution harms business ethics from the perspective of earnings manipulation, which exerts a real effect on the economy and social welfare. Using a large sample and a comprehensive air quality index in China, we find that firms located in cities with more severe air pollution exhibit higher levels of discretionary accruals and are more likely to restate their financial statements, consistent with exposure to air pollution leading to more earnings manipulation. We further provide causal evidence using (...) propensity score matching and a discontinuity regression design exploiting the Qinling Mountain–Huai River Heating Policy Line, which exogenously leads to more air pollution to cities located immediately north of the Line but not those in the south. Our findings are robust to controlling for weather conditions and alternative samples and measures of air pollution and earnings manipulation. Overall, this study unveils how the ecological environment shapes business ethics. (shrink)

The issue of assessing priorities is one that has become the subject of much debate in the National Health Service particularly in the wake of various documents on priorities from central Government. It has become even more so with the prospect of real cuts in expenditure. Economists claim that their science, or perhaps more accurately art can assist in determining not only how best to achieve various ends but also whether and to what extent competing objectives should be pursued. Such (...) choices cannot be made in the absence of some ethical considerations and it is important that health service decision makers (and in particular the medical profession) are aware if the relationship between economics (and especially cost-benefit analysis) and medical ethics.

It is argued that Hempel's original rejection of the prediction criterion of confirmation in [8] (on the grounds that it leads to a circular definition of confirmation) was ill-conceived, and that his own approach exhibits undesirable consequences to the degree that it deviates from this criterion. A version of the prediction criterion is formulated which, in addition to being-non circular, escapes the criticisms advanced against Hempel's satisfaction criterion, offers certain clear advantages over alternative approaches, and may serve as the basis (...) for a theory of qualitative confirmation. The definition of confirmation developed here violates two of Hempel's three criteria of adequacy, and in showing why it should do so some light is shed on various issues in the debate concerning the acceptability of these criteria.
