MAXIMALITY,DUPLICATION, AND INTRINSIC VALUE

In this paper, I develop an argument for the thesis that ‘maximality is extrinsic’, on which a whole physical object is not a whole of its kind in virtue of its intrinsic properties. Theodore Sider has a number of arguments that depend on his own simple argument that maximality is extrinsic. However, Peter van Inwagen has an argument in defence of his Duplication Principle that, I will argue, can be extended to show that Sider's simple argument fails. However, van Inwagen's argument fails against a more complex, sophisticated argument that maximality is extrinsic. I use van Inwagen's own commitments to various forms of causation and metaphysical possibility to argue that maximality is indeed extrinsic, although not for the mundane reasons that Sider suggests. I then argue that moral properties are extrinsic properties. Two physically identical things can have different moral properties in a physical world. This argument is a counterexample to a classical ethical supervenience idea (often attributed to G.E. Moore) that if there is identity of physical properties in a physical world, then there is identity in moral properties as well. I argue moral value is ‘border sensitive’ and extrinsic for Kantians, utilitarians, and Aristotelians.     

Assessing Workgroup Norms for Civility: The Development of the Civility Norms Questionnaire-Brief

Purpose

This research describes the development and validation of the Civility Norms Questionnaire-Brief (CNQ-B), a 4-item measure designed to assess workgroup climate for civility. Climate for civility is defined as employee perceptions of norms supporting respectful treatment among workgroup members.

Design/Methodology/Approach

Five samples (N?=?2,711) of adult employees, including two from distinct organizations and three from multiple organizations, responded to the CNQ-B and additional measures.

Findings

Evidence for the internal consistency, and convergent and discriminant validity of the CNQ-B was observed. Additionally, evidence for the criterion-related and incremental validity of the CNQ-B was demonstrated as it was a significant predictor of later-assessed incivility experiences and accounted for significant variability in work attitudes beyond incivility experiences and related measures.

Implications

The CNQ-B is a psychometrically sound instrument despite being composed of only four items. The CNQ-B can be used by researchers and practitioners alike to assess climate for civility, to study climate for civility as a precursor to incivility experiences, and to target workgroups that could benefit from interventions (e.g., training) to enhance civility and reduce incivility.

Originality/Value

This is one of the first studies to conduct a rigorous psychometric assessment of a measure of workgroup climate for civility that is grounded in theory and research on workplace civility and incivility. At four items, the CNQ-B is the shortest assessment tool currently available that is designed for this purpose.     

Smaller magnets for smarter minds?

Human brain stimulation for therapeutic purposes has many short- and long-term limitations. The possibility of implanting magnetic, rather than electrical, stimulation devices would present a possible solution to some of the problems. The development of a new microscopic magnetic stimulation device provides a glimpse of the realisation.     

Relationships between job evaluation ratings and self-ratings of job characteristics

Self-ratings by 308 shop workers of their job variety, autonomy, task identity, and skill challenge correlate significantly with ratings by observers of the jobs' skill requirements. Self-ratings, however, are unrelated to observers' estimates of the physical demands of the jobs or to environmental conditions of the work. The self-ratings and observer measures provide complementary, not substitute, information. Self-ratings can signal person-job dysfunctions, and more objective job measures can identify possible sources of the dysfunctions. Modifications to job characteristics measures are discussed and suggestions are made to begin a new phase of programmatic job characteristics research.     

Intraseptal administration of muscimol produces dose-dependent memory impairments in the rat

The present study examined the effects of intraseptal administration of the GABAergic agonist muscimol on performance of a radial-arm maze (RAM) task. Male Long-Evans rats were trained to perform a RAM task in which a 1-h delay was imposed between the sample and the test session. In this task rats have access to four out of eight maze arms during a predelay session. Following a 1-h delay, rats are returned to the maze and allowed to freely choose among all eight arms. Arms not blocked during the predelay session are baited, and entry into an arm chosen during the predelay session or a repeated entry into a postdelay chosen arm constitutes an error. Following acquisition, animals were implanted with a single cannula aimed at the medial septum. A within-subjects design was utilized to examine the effects of intraseptal administration of muscimol (0.0, 0.75, 1.5 or 3.0 nmol) on performance in this task. All drugs or artificial cerebrospinal fluid were administered immediately following the predelay session. Muscimol, a GABA-A agonist, produced a dose-dependent impairment in maze performance as evidenced by fewer correct choices in the first four postdelay choices and an increase in the number of errors. Intraseptal administration of muscimol did not significantly alter latency per choice on the RAM task nor did it affect locomotor activity levels. Muscimol-induced impairments were also observed when a 4-h delay was imposed between the fourth and the fifth maze selection, suggesting that the behavioral deficit represents an inability to store or retain spatial working memories rather than a general performance deficit. These data indicated that pharmacological manipulation of GABA-A receptors within the medial septum modifies working memory processes. The potential interaction of GABAergic and cholinergic mechanisms in the modulation of working memory processes is discussed.     

Group rearing abolishes hyperdefensiveness induced in weanling rats by lateral septal or medial accumbens lesions but not by medial hypothalamic lesions

Lesions of the medial hypothalamus, medial accumbens, or septum were made in 21- to 25-day-old male hooded rats. Half of the animals in each group were subsequently reared in groups and the other half in isolation. When tested for defensiveness toward the experimenter at 31, 34, and 37 days postoperatively, rats with medial hypothalamic lesions were most hyperdefensive toward the experimenter if reared in isolation but were significantly more defensive than sham-lesioned animals even when reared in groups. Rats with septal lesions were significantly more defensive than sham-lesioned animals only when reared in isolation while rats with medial accumbens lesions were not different from controls whether reared individually or in groups. These results suggest that the medial hypothalamus may have a special importance in determining temperament since the hyperdefensiveness that results from interference with its functioning is resistant to experiential remediation.     

Color preference and food choice among children

The effects of color on children's food choices were investigated. Subjects were 120 children who were equally distributed among each of the combinations of age (5 vs. 9 years old), sex (male vs. female), food type (3 types of candies), and color (red, green, yellow, and orange) in a counterbalanced, factorial, analysis-of-variance design with repeated measures on subjects. A significant main effect for color indicated that children preferred foods that were red, green, orange, and yellow, in that order. Interpretation of this main effect was not interfered with by main effects or interaction terms involving age, sex, or food type, which served as alternative rival hypotheses.     

The effects of unstable clients in adolescent treatment: contagion versus continuity

This study examined the effects of integrating an unstable group of seriously disturbed adolescents into an existing day treatment program. Behavioral data were collected for an established group of subjects who were in treatment one year prior to and one year after the arrival of a new group of severely disturbed adolescents. It was found that the disruptive behavior displayed by the new admission subjects was not imitated by the subjects of the established group. Rather, there was a significant decrease in aggression and in the overall number of psychiatric events for the established group. The treatment milieu was seen to be resistant to the effects of the new admissions largely due to the structured form of treatment.     

A social historical note on the formal emergence of community psychology

Recent interviews of 15 eminent community psychologists, 6 of whom attended the founding conference at Swampscott, highlighted some historically significant aspects of community psychology's emergence and provided background information concerning the conference's processes and content. The interview informants described the idealism of the era in the context of societal unrest, the struggle with psychiatrists' control of extant mental health services, and the uncertain role of a community orientation within academic psychology as key social historical factors. The informants identified some of the behind-the-scenes preparations for Swampscott as well as the conference climate and emergent ideology. The report concludes with a note on the historical status of women in the subdiscipline.
