Against <Emphasis Type="Italic">A Posteriori</Emphasis> Moral Naturalism

A posteriori Moral Naturalism posits a posteriorimoral/naturalistic identities. Versions of this view thatposit necessary identities purport to rely on theKripke/Putnam doctrine of scientific essentialism.Versions that posit only contingent identities requirethat moral terms are non-rigid designators. I argue thatmetaethics does not fall within the scope of scientificessentialism and that moral terms are not non-rigid designators.     

Learning in a Man'S World: Examining the Perceptions of Undergraduate Women in Male-Dominated Academic Areas

This study examined the perceptions of undergraduate women in male-dominated academic areas. First-year and final-year female undergraduates in a male-dominated academic area (i.e., math, science, or engineering) reported higher levels of discrimination and stereotype threat than women in a female-dominated academic area (i.e., arts, education, humanities, or social science), and men in either a male- or female-dominated academic area. Moreover, women in a male-dominated academic area were most likely to report thinking about changing their major. These findings suggest that female college students majoring in math, science, and engineering continue to perceive additional gender-based obstacles in their field.     

Colored-Speech Synaesthesia Is Triggered by Multisensory, Not Unisensory, Perception

ABSTRACT— Although it is estimated that as many as 4% of people experience some form of enhanced cross talk between (or within) the senses, known as synaesthesia, very little is understood about the level of information processing required to induce a synaesthetic experience. In work presented here, we used a well-known multisensory illusion called the McGurk effect to show that synaesthesia is driven by late, perceptual processing, rather than early, unisensory processing. Specifically, we tested 9 linguistic-color synaesthetes and found that the colors induced by spoken words are related to what is perceived (i.e., the illusory combination of audio and visual inputs) and not to the auditory component alone. Our findings indicate that color-speech synaesthesia is triggered only when a significant amount of information processing has occurred and that early sensory activation is not directly linked to the synaesthetic experience.     

Adolescent well‐being and supporting contexts: A comparison of adolescents in Ireland and Florida

The purpose of this research was to examine the extent to which social support and wider community perceptions/engagements among adolescents are connected with well‐being. We compared adolescents in two different societal contexts, Florida in the United States and County Offaly, in Ireland, and posed the questions: What are the key predictors of subjective well‐being from the various sources of support, and to what extent does the impact of social support on well‐being vary across these two societies? Questionnaires were completed and returned for 607 respondents (322 in the Irish study and 285 in the Florida study). A variety of scales were adopted and designed to operationalize our key concepts of: Adolescent well‐being, social support, school satisfaction, neighbourhood quality of life and community/voluntary participation. Our results indicate that informal social support and school satisfaction were the strongest predictors of youth well‐being in both locations, despite some differences in terms of individual influencing variables. From informal sources, emotional support from friends and advice/concrete/esteem support from parents emerged as important predictive dimensions. Liking school, perceptions of doing well in school were the main predictors of school satisfaction in Ireland while, in Florida, student camaraderie and the experience of bullying emerged as significant.

Type D Personality and Chronic Pain: Construct and Concurrent Validity of the DS14

A body of research has demonstrated that the Type D personality is a risk factor among cardiac patients. Previous studies validating the Type D Scale (DS14) across other clinical groups have not included chronic pain patients in their samples. The purpose of this study was to investigate the construct and concurrent validity of the DS14 using the MMPI-2. The DS14 and its two component subscales demonstrated strong internal consistency among chronic pain patients. The two subscales of the DS14 were found to be related to similar clinical scales on the MMPI-2, and significant differences were found in the MMPI-2 profiles of individuals with and without the Type D personality. Considerations for clinical practice and research are discussed.     

Further experiments on the social interactions of domestic “Norway” rats

Domestic rats, Rattus norvegicus, aged nearly one year, were studied in artificial colonies in large cages with attached nest boxes. As in previous experiments on younger domestic rats, but not those on wild rats, the colonies were peaceful. Questions concerning the “aggressive” or “agonistic” behavior of domestic rats are further discussed.     

Genotype and environment in the social interactions of wild and domestic “Norway” rats

Wild rats, Rattus norvegicus, (a) trapped as adults or (b) of the second generation in captivity (lab-wild), and domestic rats of two strains, were studied for 28 days in artificial colonies in large cages with attached nest boxes. Controls were kept in mated pairs in small cages. Each colony consisted of six males and six females. The interactions of the males in six colonies of trapped rats were highly “stressful;” 61% died; and most of the survivors lost weight and had greatly enlarged adrenals. In each colony, however, there was a male (an alpha) that gained in weight and spent much time, during the dark hours, in the open on the floor of the cage; and in three colonies there were also other males (“betas”) that gained in weight. The adrenals of alphas and betas weighed about the same as those of the controls. In one of the 12 colonies of domestic rats one male behaved like a wild male; but in the other colonies the males gained in body weight and their adrenal weights resembled those of the controls. In three colonies of lab-wild rats 22% of the males died, but there was no evidence of males of different status. The findings confirm that the “agonistic” behavior of domestic rats is usually much attenuated in comparison with that of the wild type; a number of methodologic implications are discussed.     

Socially induced renal pathology of captive wild rats (Rattus villosissimus)

Long-haired rats, Rattus villosissimus, were studied in large cages. Groups of adult rats (each of 3 males, or 1 male and 2 females) were observed during intermittent encounters with a male intruder for up to 9 days. Two further groups, each of 8 males and 8 females, were maintained for 70 days without introduction of intruders. Controls were kept in small cages in which intolerant behavior was rare. Behavior during attack resembled that of male R. norvegicus, but social relationships were less stable. Only observations on males are described in detail. Some rats collapsed under attack, though unwounded, and died when not removed. Collapse occurred sometimes after a few hours, but sometimes after many days of exposure. Exposure to attack was accompanied by a decline in body weight and by some adrenal hypertrophy. Two kinds of renal pathology are described: focal glomerular hypercellularity (FGH), probably due to glomerulonephritis, and dilated distal convoluted tubules. Neither condition occurred in the controls. FGH occurred in 3 of 12 rats (25%) that remained apparently healthy during the 9 days of continuous exposure, in 21 of 23 intruders (91%) that were exposed to intermittent attack over 9 days or less without becoming debilitated, and in 8 of 11 such rats (73%) that collapsed. All rats examined from 70-day colonies had FGH, whether collapsed or not. Dilated tubules occurred in 6 of 32 intruders (19%) exposed to intermittent attack, and in 2 of 6 animals that collapsed during 70 days of exposure. Renal pathology, especially glomerulonephritis, was therefore a correlate of social intolerance; but there was no evidence that it was a significant cause of death.
