I attempt to raise questions regarding elements of systematics—primarily in the realm of phylogenetic reconstruction—in order to provoke discussion on the current state of affairs in this discipline, and also evolutionary biology in general: e.g., conceptions of homology and homoplasy, hypothesis testing, the nature of and objections to Hennigian “phylogenetic systematics”, and the schism between (neo)Darwinian descendants of the “modern evolutionary synthesis” and their supposed antagonists, cladists and punctuationalists.
Although the construction of neo-Darwinism grew out of Thomas Hunt Morgan's melding of Darwinism and Mendelism, his evidence did not soley support a model of gradual change. To the contrary, he was confronted with observations that could have led him to a more "evo-devo" understanding of the emergence of novel features. Indeed, since Morgan was an embryologist before he became a fruit-fly geneticist, one would have predicted that the combination of these two lines of research would have resulted in early (...) formulations of concepts relevant to evolutionary developmental biology. It is thus of interest to review Morgan's thought processes and arguments for at first rejecting both Darwinism and Mendelism, and then for later dismissing data that would have yielded a model of rapid morphological change in favor of a model of change based on the accumulation of minor mutations and their morphological consequences.

The data emerging from the clinical and brain studies described above suggest that, in the case of OCD, there are two pertinent brain mechanisms that are distinguishable both in terms of neuro dynamics and in terms of the conscious experiences that accompany them. These mechanisms can be characterized, on anatomical and perhaps evolutionary grounds, as a lower level and a higher level mechanism. The clinical treatment has, when successful, an activating effect on the higher level mechanism, and a suppressive effect (...) on the lower level one. (shrink)

Neuropsychological research on the neural basis of behaviour generally posits that brain mechanisms will ultimately sufﬁce to explain all psychologically described phenomena. This assumption stems from the idea that the brain is made up entirely of material particles and ﬁelds, and that all causal mechanisms relevant to neuroscience can therefore be formulated solely in terms of properties of these elements. Thus, terms having intrinsic mentalistic and/or experiential content (e.g. ‘feeling’, ‘knowing’ and ‘effort’) are not included as primary causal factors. This (...) theoretical restriction is motivated primarily by ideas about the natural world that have been known to be fundamentally incorrect for more than three-quarters of a century. Contemporary basic physical theory differs profoundly from classic physics on the important matter of how the consciousness of human agents enters into the structure of empirical phenomena. The new principles contradict the older idea that local mechanical processes alone can account for the structure of all observed empirical data. Contemporary physical theory brings directly and irreducibly into the overall causal structure certain psychologically described choices made by human agents about how they will act. This key development in basic physical theory is applicable to neuroscience, and it provides neuroscientists and psychologists with an alternative conceptual framework for describing neural processes. Indeed, owing to certain structural features of ion channels critical to synaptic function, contemporary physical theory must in principle be used when analysing human brain dynamics. The new framework, unlike its classic-physics-based predecessor, is erected directly upon, and is compatible with, the prevailing principles of physics. It is able to represent more adequately than classic concepts the neuroplastic mechanisms relevant to the growing number of empirical studies of the capacity of directed attention and mental effort to systematically alter brain function..

"Modern History" versions of the etiological theory claim that in order for a trait X to have the proper function F, individuals with X must have been recently favored by natural selection for doing F (Godfrey-Smith 1994; Griffiths 1992, 1993). For many traits with prototypical proper functions, however, such recent selection may not have occurred: traits may have been maintained due to lack of variation or due to selection for other effects. I examine this flaw in Modern History accounts and (...) offer an alternative etiological theory, the Continuing Usefulness account, which appears to avoid such problems. (shrink)
With the growing focus on prevention in medicine, studies of how to describe risk have become increasing important. Recently, some researchers have argued against giving patients “comparative risk information,” such as data about whether their baseline risk of developing a particular disease is above or below average. The concern is that giving patients this information will interfere with their consideration of more relevant data, such as the specific chance of getting the disease (the “personal risk”), the risk reduction the treatment (...) provides, and any possible side effects. I explore this view and the theories of rationality that ground it, and I argue instead that comparative risk information can play a positive role in decision-making. The criticism of disclosing this sort of information to patients, I conclude, rests on a mistakenly narrow account of the goals of prevention and the nature of rational choice in medicine. (shrink)
Accounts of the concepts of function and dysfunction have not adequately explained what factors determine the line between low‐normal function and dysfunction. I call the challenge of doing so the line‐drawing problem. Previous approaches emphasize facts involving the action of natural selection (Wakefield 1992a, 1999a, 1999b) or the statistical distribution of levels of functioning in the current population (Boorse 1977, 1997). I point out limitations of these two approaches and present a solution to the line‐drawing problem that builds on the (...) second one. (shrink)

This paper accepts as given that business students want to get ahead. It criticizes business schools for their failure to reduce the incongruence between doing what is right and doing what it takes to get ahead. Because of this failure business school graduates carry negative ideas, attitudes and behaviors vis-à-vis social responsibility from business schools into the business world. Recommendations are made for increasing the social responsibility of business schools.
A multilevel view of social change is presented in which socially responsible organizations, society, and high-hope individuals interact in support of hopefulness – thereby leveling the playing field. Suggestions are made about future research and the roles of organizations and society in eliciting hope in organizational and societal cultures.
The antireductionist arguments of many philosophers (e.g., Baker, Fodor and Davidson) are motivated by a worry that successful reduction would eliminate rather than conserve the mental. This worry derives from a misunderstanding of the empiricist account of reduction, which, although it does not underwrite "cognitive suicide", should be rejected for its positivist baggage. Philosophy of psychology needs more detailed attention to issues in natural science which serve as analogies for reduction of the mental. I consider a range of central cases, (...) including water and H 2 O, genes and DNA, and common sense and scientific solidity. The last case is illuminated by Eddington's Two Tables paradox, a resolution which suggests the plasticity of the mental under reduction. If reduction of the mental is like any of these cases, it is neither empiricist nor eliminative. (shrink)
In a recent paper in Business Ethics Quarterly Professor Jeffrey Moriarty (2005) asserted the relevance of political philosophy to business ethics. Moriarty asked whether "businesses ought to be run (more) like states" and argued why that might be beneficial. This paper on the contrary asserts that there are distinct disadvantages to businesses attempting to be run more like states. Specifically, it asserts that any such an attempt increases the likelihood of the re-emergence of a totalitarian society as businesses currently (...) often act as an intermediary between the individual and the state. The paper contemplates Moeller's ambitions in the Weimar period for the business to be run like a state and the historical outcome of those ambitions. The paper also distinguishes between two different kinds of rights and argues that different kinds of rights pertain to different sectors which preclude business being run like a state. (shrink)
This study examines values and value types as well as scores in levels of moral reasoning for␣students enrolled in a business program. These two factors are measured using the Schwartz Personal Values␣Questionnaire and the Defining Issues Test 2. No statistically significant differences in levels of moral␣reasoning, rankings of values, and value types could be attributed to gender. However, eight significant correlations between value types and levels of moral reasoning provide evidence that a systematic relationship exists. The relationships are not (...) only internally consistent but also consistent with the model of values based on motivational goals (Schwartz S. H. and K. Boenke: 2004, Journal of Research in Personality, 38 230–255). (shrink)

Three studies investigated implicit brand attitudes and their relation to explicit attitudes, prod- uct usage, and product differentiation. Implicit attitudes were measured using the Implicit As- sociation Test (IAT; Greenwald, McGhee, & Schwartz, 1998). Study 1 showed expected differ- ences in implicit attitudes between users of two leading yogurt brands, also revealing significant correlations between IAT-measured implicit attitudes and explicit attitudes. In Study 2, users of two fast food restaurants (McDonald’s and Milk Bar) showed implicit attitudi- nal preference for (...) their favorite restaurant. In Study 3, implicit attitudes of users of two soft drinks (Coca-Cola and Pepsi) predicted brand preference, product usage, and brand recognition in a blind taste test. A meta-analytic combination of the three studies showed that the use of IAT measures increased the prediction of behavior relative to explicit attitude measures alone. (shrink)
Shepard's analysis of how shape, motion, and color are perceptually represented can be generalized. Apparent motion and shape may be associated with a group of spatial transformations, accounting for rigid and plastic motion, and perceived object color may be associated with a group of illuminant transformations, accounting for the discriminability of surface-reflectance changes and illuminant changes beyond daylight. The phenomenological and mathematical parallels between these perceptual domains may indicate common organizational rules, rather than specific ecological adaptations. [Barlow; Hecht; Kubovy & (...) Epstein; Schwartz; Shepard; Todorovic]. (shrink)
