Social Support,Caregiver Burden,and Life Satisfaction in a Sample of Rural African American and White Caregivers of Older Persons With Dementia

This article reports the findings of a study of African American and White dementia caregivers (n = 141) living in rural areas of Alabama that examined the relations between the participants' receipt of informal social support, and their levels of caregiver burden and life satisfaction. The sample, as a whole, reported high levels of social support with no reported differences in social support by race. Female caregivers reported higher mean scores on 3 of the 4 dimensions of social support than their male counterparts. Two of the 4 dimensions of social support accounted for 32% of the variance of the caregivers' reported level of life satisfaction.     

Influences on Authorship Issues: An Evaluation of Receiving,Not Receiving,and Rejecting Credit

A survey on credit issues was conducted of academic chemists in Ph.D. granting institutions in the United States. Six-hundred faculty members responded representing 16% of the survey recipients. Fifty percent of the respondents reported not receiving appropriate credit for contributions they had made to published projects. Neither the number of years after receiving their Ph.D., their fields of expertise, their total number of publications, nor their total number of single-author publications showed any significant relationship with the perception of not receiving appropriate credit. Twenty percent of the respondents had discovered that they were an author of a paper, after that paper had been submitted to a journal. Forty-nine percent reported that they had asked to have their name deleted as an author. Relationships between these perceptions and academic background factors were examined. For example, respondents who had asked to be removed from authorship were more likely to give authorship or an acknowledgement to others and were also more likely to have had an authorship problem with others, both of these factors being related to longevity as a publishing scientist.     

Post-War trends in Maori population growth

Recent levels and trends of mortality and fertility of the minority Maori population of New Zealand are analysed. On this basis two projections for the year 1976 are presented, the first assuming a further rise in life expectation, which has already increased rapidly over the last two decades; and the other that both mortality and the consistently high fertility levels will be reduced. The conclusion is that, regardless of which projection one accepts, growth will be rapid (an increase of 60% to 70% in the period 1961–76), although the age distribution will be different at the youngest ages. Unless fertility is reduced, as in Projection 2, the dependency burden of Maori family heads will be extremely heavy.     

The Discursive Construction of Women Politicians in the European Press

The appointment of the first majority female government in Spain generated a significant amount of coverage in newspapers across Europe, synthesising the multi-faceted debate about the relationship between gender and political leadership. Through the combination of qualitative thematic and quantitative content analysis, this article examines the construction of women politicians across different European nations. By analysing the coverage of the issue in the main newspapers of four European countries (France, Italy, Spain and the UK) in the two weeks after the new Spanish cabinet was appointed, this article explores the values and ideal roles the media assign to female politicians. The article is based on the premise that mediated representations of female politicians can tell us important things about the relations between gender, power and politics. Such representations embody a set of assumptions about how successful women should look, behave and speak, and thus implicitly express judgments on models of femininity. Ultimately, such representations construct heroines and villains that inform our conceptions of women's political participation, thereby encouraging some forms of gendered political discourse and discouraging others. Our research found that while certain discourses celebrate women ministers for their (symbolic) emancipatory value, others judge them by their physical appearance or their performance as wives, mothers, and mothers-to-be.     

Nonverbal Auditory Cues Allow Relationship Quality to be Inferred During Conversations

Associations between acoustic features of maternal speech and infants’ emotion regulation following a social stressor

Caregiver voices may provide cues to mobilize or calm infants. This study examined whether maternal prosody predicted changes in infants’ biobehavioral state after the still face, a stressor in which the mother withdraws and reinstates social engagement. Ninety-four dyads participated in the study (infant age 4–8 months). Infants’ heart rate and respiratory sinus arrhythmia (measuring cardiac vagal tone) were derived from an electrocardiogram (ECG). Infants’ behavioral distress was measured by negative vocalizations, facial expressions, and gaze aversion. Mothers’ vocalizations were measured via a composite of spectral analysis and spectro-temporal modulation using a two-dimensional fast Fourier transformation of the audio spectrogram. High values on the maternal prosody composite were associated with decreases in infants’ heart rate (β = ?.26, 95% CI: [?0.46, ?0.05]) and behavioral distress (β = ?.23, 95% CI: [?0.42, ?0.03]), and increases in cardiac vagal tone in infants whose vagal tone was low during the stressor (1 SD below mean β = .39, 95% CI: [0.06, 0.73]). High infant heart rate predicted increases in the maternal prosody composite (β = .18, 95% CI: [0.03, 0.33]). These results suggest specific vocal acoustic features of speech that are relevant for regulating infants’ biobehavioral state and demonstrate mother–infant bi-directional dynamics.     

Power analysis for cluster randomized trials with binary outcomes modeled by generalized linear mixed-effects models

Power analysis for cluster randomized control trials is difficult to perform when a binary response is modeled using the generalized linear mixed-effects model (GLMM). Although methods for clustered binary responses exist such as the generalized estimating equations, they do not apply to the context of GLMM. Also, because popular statistical packages such as R and SAS do not provide correct estimates of parameters for the GLMM for binary responses, Monte Carlo simulation, a popular ad-hoc method for estimating power when the power function is too complex to evaluate analytically or numerically, fails to provide correct power estimates within the current context as well. In this paper, a new approach is developed to estimate power for cluster randomized control trials when a binary response is modeled by the GLMM. The approach is easy to implement and seems to work quite well, as assessed by simulation studies. The approach is illustrated with a real intervention study to reduce suicide reattempt rates among US Veterans.     

Supply risk mitigation: a multi-theoretical perspective

Due to the increasing level of supply risk, it is imperative to obtain a better understanding of the nature of risk which is a premise to developing well-grounded risk mitigation strategies. This paper examines how to mitigate supply risk enlightened by discussing the concept of risk in association of three closely related concepts which are uncertainty, variability and trust. The proposed three perspectives are supported and explained using four case studies comprising of two manufacturers based in Australia and four suppliers based in China. The study provides evidence that supply risk can be mitigated by high level of information and knowledge sharing as well as building trust, commitment and goal congruence in a buyer–supplier relationship. It offers theoretical and managerial implications.     

The configurational effects of board monitoring and the institutional environment on CEO compensation: a country-level fuzzy-set analysis

This study examines the causal complexity of how the effectiveness of board monitoring influences CEO compensation around the world. Previous research drawing from the managerial power theory and ‘increased career risks’ perspective offer alternative arguments for how low and high levels of effective monitoring by boards of directors influence CEO compensation. Adopting a configurational approach using fuzzy-set qualitative comparative analysis, we explore the idea that there are multiple causal paths leading to high levels of CEO compensation, such that theoretical logic from both theories may be relevant contingent upon the institutional environment in which the relationship is embedded. Our findings in a sample of 38 countries suggest that high CEO compensation is an outcome of both the presence and absence of effective board monitoring depending upon how it combines with minority investor protections and the cultural dimensions of power distance, uncertainty avoidance, and individualism, as well as the overall stock market value. Specifically, in countries with high levels of effective board monitoring, high CEO compensation will be more likely when the country’s culture is high in uncertainty avoidance, low in power distance and when there are strong protections for minority investors. Whereas in countries with low levels of effective board monitoring, high CEO compensation will be more likely when power distance is high and uncertainty avoidance is low and when there are weak protections for minority investors. Our country-level study highlights the theoretical strengths of employing a configurational approach to explore the complex interrelationships of governance mechanisms and the contexts in which they manifest.
