During the 1920s and 1930s, many biologists questioned the viability of Darwin’s theory as a mechanism of evolutionary change. In the early 1940s, and only after a number of alternatives were suggested, Darwinists succeeded to establish natural selection and gene mutation as the main evolutionary mechanisms. While that move, today known as the neo-Darwinian synthesis, is taken as signalling a triumph of evolutionary theory, certain critical problems in evolution—in particular the evolution of animal function—could not be addressed with this approach. (...) Here I demonstrate this through reconstruction of the evolutionary theory of Joseph Needham (1900–1995), who pioneered the biochemical study of evolution and development. In order to address such problems, Needham employed Herbert Spencer’s principles of emergence and Ernst Haeckel’s theory of recapitulation. While Needham did not reject Darwinian theory, Spencerian and Haeckelian frameworks happened to better fit his findings and their evolutionary relevance. He believed selectionist and genetic approaches to be important but far from sufficient for explaining how evolutionary transformations occur. (shrink)
Abstract Relying on developmental studies of reasoning about the good life, a model of moral education that integrates the good and the right is put forth. It is claimed that while Kohlberg's justice reasoning provides a justifiable aim for such curricula, how individuals attribute value will also significantly affect their moral actions. The notion of a ?critical period? for moral education during adolescence is also presented.
Abstract This long?term study found that moral reasoning as conceptualised by Kohlberg (1981, 1985) can develop into adulthood. Predominantly white, well?educated, middle?class participants were interviewed four times at 4?year intervals (N = 44). Stage development was sequential and continued throughout the life span, although its occurrence decreased with advancing age in a curvilinear fashion. Post?conventional reasoning was demonstrated by seven adults. Stage of moral reasoning correlated with age strongly in children and moderately in adults, and was moderately correlated with education (...) in all age groups. Additionally, advance in moral reasoning stage was correlated with increase in education in adults. Although no systematic gender differences were found across age groups, men in the younger adult group had significantly higher scores than women. (shrink)
Male piglets in Belgium are still castrated unanesthetized in the first week of life, but animal rights organizations, supermarkets, and some consumers no longer accept this method in terms of animal welfare, and are pushing the pig industry to apply available alternative methods. This major change in pig husbandry will increase production costs without a guarantee for return of investment by consumers. Therefore, it is important to know the opinion of consumers on this matter. A questionnaire was used to collect (...) data from 1,018 people through face to face interviewing in Flanders. A Chi-square test and Fisher’s exact test were used to analyze the data. Results show that in spite of several media campaigns of animal welfare organizations over the past few years, still half of the Flemish respondents were not aware of the problem of unanesthetized piglet castration. However, after being informed, the majority wanted unanesthetized castration to be banned. Although the concern about animal welfare implications was very high, the willingness to pay extra for alternatives was low. (shrink)

The computation of both Scalar Implicatures (SI) and Association with Focus (AF) is characterized with reference to sets of alternatives. However, it has generally been assumed that the relevant alternatives are determined in different ways for the two processes. Specifically, it has been assumed that the alternatives for SI – scalar alternatives – are computed by a special procedure specifically designed for implicatures, whereas the alternatives for AF – focus alternatives – are determined by the general theory of association with (...) focus – focus semantics. As far as we know, the only attempt to connect the two is Krifka (1995), under which scalar alternatives and focus alternatives are identical and determined by focus semantics. However, Krifka’s result is based on a specific stipulation about scalar items, which he borrows from Horn and incorporates into focus semantics, namely that scalar items are inherently focused and have their Horn Scale as their lexically specified focus values.

Scalar implicatures depend on alternatives in order to avoid the symmetry problem. I argue for a structure-sensitive characterization of these alternatives: the alternatives for a structure are all those structures that are at most as complex as the original one. There have been claims in the literature that complexity is irrelevant for implicatures and that the relevant condition is the semantic notion of monotonicity. I provide new data that pose a challenge to the use of monotonicity and that support the (...) structure-sensitive definition. I show that what appeared to be a problem for the complexity approach is overcome once an appropriate notion of complexity is adopted, and that upon closer inspection, the argument in favor of monotonicity turns out to be an argument against it and in favor of the complexity approach.

In his recent paper on the symmetry problem Roni Katzir argues that the only relevant factor for the calculation of any Quantity implicature is syntactic structure. I first refute Katzir’s thesis with three examples that show that structural complexity is irrelevant to the calculation of some Quantity implicatures. I then argue that it is inadvisable to assume—as Katzir and others do—that exactly one factor is relevant to the calculation of any Quantity implicature.
This study explored the influence of personal values on destructive leader behavior. Student participants completed a managerial assessment center that presented them with ambiguous leadership decisions and problems. Destructive behavior was defined as harming organizational members or striving for short-term gains over long-term organizational goals. Results revealed that individuals with self-enhancement values were more destructive than individuals with self-transcendence values were, with the core values of power (self-enhancement) and universalism (self-transcendence) being most influential. Results also showed that individuals defined and (...) structured leadership problems in a manner that reflected their value systems, which in turn affected the problem solutions they generated.

We examine the link between the growing emphasis on corporate social responsibility at the organizational level and beliefs about social responsibility at work (SRW) expressed by individuals. Drawing from theories of professionalism and diffusion of innovations (including practices and beliefs), we advance hypotheses about beliefs of managers and non-managers in 11 countries at two time periods, and use a unique international data set to test our hypotheses. Our general prediction that managers would score higher than non-managers on a measure of (...) SRW was not supported. However, further analysis revealed a more complex relationship moderated by the contextual factors of time frame and country inequality level. We discuss implications and extensions for future research. (shrink)
The semantics of association with focus and the pragmatic conditions governing the appropriateness of focus in discourse are usually taken to depend on focus alternatives. According to a common view, these alternatives are generated by a permissive process. This permissive view has been challenged by Michael Wagner, who has noted that certain alternatives are systematically excluded from consideration. Wagner describes a more restrictive view, on which only contrastive alternatives are relevant for association with focus and for the appropriateness of focus (...) in discourse. I use recent work on the role of contradiction to show that the standard, permissive view derives the same results as the contrast-based view for the basic cases. These basic cases involve a contradiction that prevents us from using them to distinguish the two approaches. I show that when this contradiction is eliminated, evidence of non-contrastive alternatives emerges, supporting the permissive standard view over the restrictive contrast-based one. (shrink)
