Responses of calves to acute stress: Individual consistency and relations between behavioral and physiological measures

The present study examined the consistency over time of individual differences in behavioral and physiological responsiveness of calves to intuitively alarming test situations as well as the relationships between behavioral and physiological measures. Twenty Holstein Friesian heifer calves were individually subjected to the same series of two behavioral and two hypothalamo-pituitary-adrenocortical (HPA) axis reactivity tests at 3, 13 and 26 weeks of age. Novel environment (open field, OF) and novel object (NO) tests involved measurement of behavioral, plasma cortisol and heart rate responses. Plasma ACTH and/or cortisol response profiles were determined after administration of exogenous CRH and ACTH, respectively, in the HPA axis reactivity tests. Principal component analysis (PCA) was used to condense correlated measures within ages into principal components reflecting independent dimensions underlying the calves' reactivity. Cortisol responses to the OF and NO tests were positively associated with the latency to contact and negatively related to the time spent in contact with the NO. Individual differences in scores of a principal component summarizing this pattern of inter-correlations, as well as differences in separate measures of adrenocortical and behavioral reactivity in the OF and NO tests proved highly consistent over time. The cardiac response to confinement in a start box prior to the OF test was positively associated with the cortisol responses to the OF and NO tests at 26 weeks of age. HPA axis reactivity to ACTH or CRH was unrelated to adrenocortical and behavioral responses to novelty. These findings strongly suggest that the responsiveness of calves was mediated by stable individual characteristics. Correlated adrenocortical and behavioral responses to novelty may reflect underlying fearfulness, defining the individual's susceptibility to the elicitation of fear. Other independent characteristics mediating reactivity may include activity or coping style (related to locomotion) and underlying sociality (associated with vocalization). (c) 2005 Elsevier Inc.

The Rights of Religious Associations to External Relations: A Comparative Study of the OSCE and the Council of Europe

This paper argues that religious associations have a number of substantive rights when it comes to their external relations. It does so though comparing the position of the OSCE and the Council of Europe. This paper considers whether the emerging framework includes: (1) a right to legal entity status, (2) a right to establish and run charitable or educational institutions, (3) a right to privileges and substantive benefits and (4) a right to anything else. It concludes that the current developments are welcome because religious freedom has a collective aspect that is essential to the lives of many believers.

Organisational Self-Evaluation and Teacher Education for Community Relations in a Transforming Society?

During 2004, the School of Education at the University of Ulster embarked on an innovative three-year project designed to embed community relations objectives within initial teacher education. With the advent of more peaceful times in Northern Ireland, this was a precipitous time for initial teacher educators to review the preparation given to beginner teachers for teaching in an increasingly pluralist society emerging from conflict. The present paper reports on one very specific and time-limited element of the broader project. That is, development work designed to investigate the possibilities of using processes of self-review and evaluation as a lever for improvements in initial teacher education for community relations. Following a brief contextualisation, the background to, and the development of, a set of materials designed to support rigorous and systematic self-review of all aspects of provision in a university-based initial teacher education department is described. The Community Relations Index for Initial Teacher Education (Cr-ITE) was envisaged as being of use to initial teacher education establishments in order to help teacher educators take responsibility for rigorous learning from their practice, whilst placing inclusive values at the centre of organisational development. The final section includes further critical reflection on the role of organisational self-review in transforming teacher education for inclusion in a society emerging from longstanding communal conflict.

Are Good Industrial Relations Good for the Economy?

Recent US microeconomic analysis indicates that good industrial relations might improve firm performance. Of late, it has also been claimed that the benefits of industrial relations quality - proxied inversely by a strikes variable - could also extend to the macroeconomy. Using cross-country data, we find that, independent of other labor market institutions, a lower strike volume is associated with lower unemployment. Although there is a separate line of causation running from unemployment to strikes, our analysis suggests that this is not dominant. That said, support for the notion that macro performance owes something to good industrial relations is, however, weakened once we formally control for strike endogeneity.
