Construed external image and organizational identification: a test of the moderating influence of need for self-esteem

According to Social Identity Theory (cf., J. G. March & H. A. Simon, 1958), individuals tend to identify with prestigious or high-status groups. Researchers (J. E. Dutton, J. M. Dukerich, & C. V. Harquail, 1994) have revealed that organizational members also identify with organizations that have attractive public images. To gain a better understanding of the theoretical reasons underlying the relationship between image and identification in organizations, the authors examined this relationship in a healthcare setting. In addition, they investigated need for esteem as a moderator of the relationship between construed external image and organizational identification. Consistent with previous findings, the present results indicated that construed external image is positively related to organizational identification. Perhaps it is more important that the present findings also supported need for esteem as a moderator of the relationship between construed external image and organizational identification.     

PROBLEMS IN ESTABLISHING NORMS FOR CROSS-CULTURAL COMPARISONS

Problèmes de l'établissement des normes dans les comparisons interculturelles. — En examinant plusieurs des méthodes employées pour comparer les attitudes et les pratiques de parents allemands et américains relativement à l'éducation des enfants, nous avons abouti aux conclusions suivantes, susceptibles de s'appliquer à toutes les études comparatives interculturelles. 1. Les observations rollectées dans une culture et réduites à des moyennes ne peuvent servir à en évaluer une autre. — 2. Il faudrait étudier des problèmes spécifiques plutôt que des problèmes généraux ou globaux; on peut s'attendre à trouver des configurations complexes dans les différences observées. — 3. Les variables susceptibles ou non de modification selon l'âge de l'enfant, augmentent la complexité des comparaisons entre cultures. — 4. Une norme basée sur une culture n'est probablement pas valable pour une autre. — 5. Les méthodes basées sur l'utilisation d'observateurs bi-culturels semblent réduire au minimum la possibilité d'erreurs systéamatiques et la dépendance vis-à-vis de normes non-équivalentes. — 6. Les questions et les résponses de type opératoire et comportemental augmenteront, mais ne garantiront pas, la précision et la validité de l'instrument employé. — 7. Les questions ouvertes ne peuvent permettre de différencier les éléments non importants, très évidents ou uniformes des comportements ou des attitudes. — 8. Actuellement, on ne peut que rarement détecter les causes du comportement. Il n'est peut-être pas possible de les mettre en évidence, en dehors des cas où plusieurs méthodes différentes et différentes sortes de questions donnent des résultats cohérents. — 9. Il est nécessaire d'isoler un très grand nombre de variables dans chaque culture avant de pouvoir faire des comparaisons interculturelles satisfaisantes. l'utilisation de moyens électroniques pourrait faciliter le travail.     

The human genome project,predictive testing and insurance contracts: Ethical and legal responses

Conclusion The economic costs to the insurers of complementary routine genetic testing would outweigh the benefits. However, should testing technology in future be refined so as to produce a cheap and reliable test, there is no reason why insurers might not take up predictive testing as part of the normal underwriting process. It is this possibility which justifies formulating a pre-emptive policy. At the very least, there are reasons for promoting and protecting the welfare of the proposer so as to redress the bargaining positions between him or her as a consumer of a service and the insurer as a commercial concern. Further considerations relate to the social purpose of insurance as a social mechanism, and the need to find ways of avoiding undermining this in light of Human Genome Project.     

Educational and career aspirations of secondary school students in Grenada following the American intervention

This paper reports a study of educational and occupational aspirations of secondary school students in Grenada following the 1983 American intervention. Questionnaire data were obtained from 729 students attending 7 of the island's 18 secondary schools. A status attainment model containing parental and family characteristics was tested. It was discovered that Grenadian students have exceptionally and unrealistically high aspirations. Although the opportunity structure in Grenada is very limited compared to that in the United States, the island's students have higher levels of aspirations. The status attainment model was not very useful in explaining either educational or occupational aspirations, as the levels of explained variance were less than 5%. The implications of high aspirations and low opportunities for the future of Grenada are discussed.     

Peak shift in honey bee olfactory learning

If animals are trained with two similar stimuli such that one is rewarding (S+) and one punishing (S?), then following training animals show a greatest preference not for the S+, but for a novel stimulus that is slightly more different from the S? than the S+ is. This peak shift phenomenon has been widely reported for vertebrates and has recently been demonstrated for bumblebees and honey bees. To explore the nature of peak shift in invertebrates further, here we examined the properties of peak shift in honey bees trained in a free-flight olfactory learning assay. Hexanal and heptanol were mixed in different ratios to create a continuum of odour stimuli. Bees were trained to artificial flowers such that one odour mixture was rewarded with 2 molar sucrose (S+), and one punished with distasteful quinine (S?). After training, bees were given a non-rewarded preference test with five different mixtures of hexanal and heptanol. Following training bees’ maximal preference was for an odour mixture slightly more distinct from the S? than the trained S+. This effect was not seen if bees were initially trained with two distinct odours, replicating the classic features of peak shift reported for vertebrates. We propose a conceptual model of how peak shift might occur in honey bees. We argue that peak shift does not require any higher level of processing than the known olfactory learning circuitry of the bee brain and suggest that peak shift is a very general feature of discrimination learning.     

A little bit transparent with one another: Constructing vulnerability in the evangelical discourse of women preachers

Using four categories of Brown’s shame resilience theory (SRT), this paper analyses two similar online videos by prominent American evangelical female preachers: Joyce Meyer and Beth Moore. As each unpacks her survivor’s story of childhood sexual abuse, SRT (and its components of vulnerability, critical awareness, reaching out and speaking shame) can provide a matrix for interpreting the narrative in which each preacher frames her self-disclosure.     

Leg Asymmetries and Coordination Dynamics in Walking

Models of interlimb coordination (H. Haken, J. A. S. Kelso, &; H. Bunz, 1985 Haken, H., Kelso, J. A. S. and Bunz, H. 1985. A theoretical model of phase transitions in human hand movements. Biological Cybernetics, 51: 347–356. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; P. N. Kugler &; M. T. Turvey, 1987 Kugler, P. N. and Turvey, M. T. 1987. Information, natural law, and the self-assembly of rhythmic movement, Hillsdale, NJ: Erlbaum.  [Google Scholar]) were tested in walking by examining the role of asymmetries between limbs. Participants walked on a treadmill with and without a metronome. Five asymmetry conditions were created via ankle loads of 0, 3, or 6 kg on either leg. With the metronome, participants matched the target period. Without the metronome, stride rate slowed as the mass was increased on either leg. The loads led to an increase in stride period that was predicted by Huygens’ law and the hybrid pendulum-spring model. In agreement with extended Haken–Kelso–Bunz model predictions, leg asymmetries led to deviations from antiphase coordination. Also, perception–action coordination was influenced by the asymmetry between the legs and metronome. In contrast, no predicted stability effects were observed. These findings reveal that some properties of interlimb coordination, apparent in laboratory-based tasks, can also be observed in human walking.     

Boundary Conditions of the High‐Investment Human Resource Systems‐Small‐Firm Labor Productivity Relationship

Although a few published, multiindustry, firm‐level, empirical studies have linked systems of high‐investment or high‐performance human resource management practices to enhanced small‐firm performance, this stream of strategic human resource management research is underdeveloped and equivocal. Accordingly, in this study, we use a sample of for‐profit, private‐sector, small Canadian firms with fewer than 100 employees from a variety of industry sectors to examine boundary conditions of the relationship between firm‐level high‐investment human resource systems and objective small‐firm labor productivity. Congruent with contingency theory, this study's results indicate that the extent and nature of the influence of high‐investment human resource systems on objective small‐firm labor productivity is contingent on internal (differentiation strategy and firm capital intensity) and external boundary conditions (industry dynamism and industry growth). Implications and limitations of this research study as well as avenues for future research are discussed.     

Decoding overlapping memories in the medial temporal lobes using high-resolution fMRI

The hippocampus is proposed to process overlapping episodes as discrete memory traces, although direct evidence for this in human episodic memory is scarce. Using green-screen technology we created four highly overlapping movies of everyday events. Participants were scanned using high-resolution fMRI while recalling the movies. Multivariate pattern analysis revealed that the hippocampus supported distinct representations of each memory, while neighboring regions did not, demonstrating that the human hippocampus maintains unique pattern-separated memory traces even when memories are highly overlapping. The hippocampus also contained representations of spatial contexts that were shared across different memories, consistent with a specialized role in processing space.
