Maternal and child contributions to cortisol response to emotional arousal in young children from low-income, rural communities

Relations of maternal and child characteristics to child cortisol reactivity to and recovery from emotional arousal were examined prospectively at approximately 7 months of age (infancy) and then again at approximately 15 months of age (toddlerhood). The sample was diverse and population based (N = 1,292 mother-infant dyads) and included families from predominantly low-income, rural communities. Maternal behavior, family income-to-need ratio and social advantage, and child temperament, attention, and mental development were assessed, and children's saliva was sampled before and after standardized procedures designed to elicit emotional arousal. Maternal engagement in infancy was associated with greater cortisol reactivity at the infancy assessment and with reduced overall cortisol level at the toddler assessment. Also at the toddler assessment, child attention, mental development, and temperamental distress to novelty were associated with increased cortisol reactivity and regulation, whereas temperamental distress to limitations and African American ethnicity were associated with reduced cortisol reactivity. Findings are consistent with prior work linking early caregiving to the development of the hypothalamic-pituitary-adrenal axis stress response system and with a conceptual model in which developing temperament is characterized by the interplay of emotional reactivity and the emergence of the ability to effortfully regulate this reactivity using attention.     

Relative reinforcer rates and magnitudes do not control concurrent choice independently

One assumption of the matching approach to choice is that different independent variables control choice independently of each other. We tested this assumption for reinforcer rate and magnitude in an extensive parametric experiment. Five pigeons responded for food reinforcement on switching-key concurrent variable-interval variable-interval schedules. Across conditions, the ratios of reinforcer rates and of reinforcer magnitudes on the two alternatives were both manipulated. Control by each independent variable, as measured by generalized-matching sensitivity, changed significantly with the ratio of the other independent variable. Analyses taking the model-comparison approach, which weighs improvement in goodness-of-fit against increasing number of free parameters, were inconclusive. These analyses compared a model assuming constant sensitivity to magnitude across all reinforcer-rate ratios with two alternative models. One of those alternatives allowed sensitivity to magnitude to vary freely across reinforcer-rate ratios, and was less efficient than the common-sensitivity model for all pigeons, according to the Schwarz-Bayes information criterion. The second alternative model constrained sensitivity to magnitude to be equal for pairs of reinforcer-rate ratios that deviated from unity by proportionately equal amounts but in opposite directions. This model was more efficient than the common-magnitude-sensitivity model for 2 of the pigeons, but not for the other 3. An analysis of variance, carried out independently of the generalized-matching analysis, also showed a significant interaction between the effects of reinforcer rate and reinforcer magnitude on choice. On balance, these results suggest that the assumption of independence inherent in the matching approach cannot be maintained. Relative reinforcer rates and magnitudes do not control choice independently.     

When explanations for layoffs are not enough: Employer's integrity as a moderator of the relationship between informational justice and retaliation

Victims of downsizing often perceive their layoff as being unfair, which can lead to various forms of retaliation. Informational justice, defined as providing employees with adequate explanations in a timely manner, has been prescribed as a way to mitigate the retaliation tendencies associated with unfairness perceptions. Few studies, however, have examined contexts in which informational justice might be more vs. less effective in this regard. In the present research, we explored whether employees' perception of the employer's integrity moderates the relationship between informational justice and retaliation among layoff victims. Results from a field and laboratory study suggest that informational justice helps manage retaliation only when layoff victims perceived that their employer had high (vs. low) integrity prior to the layoff. In Study 2, we found that perceived sincerity mediated the impact of informational justice by integrity interaction on retaliation.     

Exploration of the attitudes of employees towards the provision of counselling within a profit‐making organisation

The provision of workplace counselling has risen significantly over the last 20 years in response to the increase in stress‐related illness amongst employees in UK profit‐making organisations. Despite this expansion there is very little exploration of employee attitudes towards this provision. This paper describes a case study of employee attitudes towards counselling in a UK profit‐making organisation utilising an Employee Assistant Programme (EAP) for staff counselling. The method used for the research was a quantitative approach administered using a short questionnaire distributed to employees by e‐mail. The responses to the questionnaire illustrated that most employees were highly aware of the service and believed stress to be the highest presenting issue to the EAP counsellors. However, stress was actually the lowest presenting issue. The results from this study also suggested that managers had a more negative attitude towards counselling than non‐managers. Men and women were found to have the same highly positive attitude towards counselling. Respondents felt that wider, constant and regular positive promotion of counselling, by the employer as well as the EAP, was needed to increase utilisation of the EAP counselling service. Concerns over confidentiality for those using, or contemplating using, the service were also found — as in other studies — but this study found concerns particularly in relation to managers finding out that an employee had attended counselling. The implications of these findings are discussed.     

The interplay of boundaryless and protean careers: Combinations and implications

The boundaryless and protean career concepts are compared in this article. It is suggested that the theories can be more finely delineated to produce more effective theory and research. The boundaryless career concept is profiled according to Sullivan and Arthur’s (this issue) categories of psychological and physical boundarylessness. The protean career concept is discussed based upon the degree of self-directed and values driven career orientations a career actor demonstrates. We join these respective boundaryless and protean delineations to produce eight likely career profiles based upon combinations of the boundaryless and protean career orientations. These eight profiles are examined in terms of challenges to career actors and those who assist them in their career development.     

The Irreducible Complexity of Objectivity

The terms ``objectivity'' and ``objective'' are among the mostused yet ill-defined terms in the philosophy of science and epistemology. Common to all thevarious usages is the rhetorical force of ``I endorse this and you should too'', orto put it more mildly, that one should trust the outcome of the objectivity-producing process.The persuasive endorsement and call to trust provide some conceptual coherenceto objectivity, but the reference to objectivity is hopefully not merely an attemptat persuasive endorsement. What, in addition to epistemological endorsement,does objectivity carry with it? Drawing on recent historical and philosophical work,I articulate eight operationally accessible and distinct senses of objectivity.While there are links among these senses, providing cohesion to the concept, I argue thatnone of the eight senses is strictly reducible to the others, giving objectivity itsirreducible complexity.     

Fundamental Dilemmas in Contemporary Psychodynamic and Insight-Oriented Psychotherapy

Contemporary psychotherapists are being called on to provide treatment with increased degrees of brevity and efficacy. To meet these demands, the practice of brief psychodynamic psychotherapy has turned to (a) the increased emphasis upon a specific psychodynamic focus for treatment versus the more comprehensive goals of longer-term treatment, and (b) the augmented use of confrontation of psychological defenses versus the enhanced use of emotional support as in more nondirective psychotherapy. Other approaches to insight-oriented psychotherapy that have been influenced by this trend include: client-centered psychotherapy with its focus upon the therapeutic relationship; existential psychotherapy with its focus upon death anxiety; and, the revitalization of interpersonal psychotherapy from its original Sullivanian conceptualization. The clinical dilemmas that limitations of time and restricted therapeutic focus place upon each of these methods of treatment are the central issues of this discussion.
