Positive and Negative Emotional Feelings and Behaviors in Mother-Daughter Ties in Late Life.

Behaviors and emotions during specific visits may reveal the interpersonal processes of mother-daughter ties, yet most research uses global assessments of these ties. Forty-eight mother-daughter pairs participated in audiotaped conversations and completed surveys. All mothers were over age 70 and in good health. Daughters tended to take a central role in structuring the conversations. Conversations were characterized by high levels of felt and expressed positive emotions and behaviors for mothers and daughters. Nevertheless, mothers reported more positive and fewer negative emotions, whereas daughters expressed more positive behaviors than did mothers. Mothers' positive feelings and behaviors were associated with daughters'. Finally, mothers' and daughters' emotions and behaviors were associated with their destructive responses to being upset with each other, providing support for the ambivalence perspective of parent-offspring relationships.

The Medical Expenditure Panel Survey: a national health information resource

This article describes the Medical Expenditure Panel Survey (MEPS), the third in a series of nationally representative surveys of medical care use and expenditures sponsored by the Agency for Health Care Policy and Research. The MEPS is designed to provide extensive data on the types of health care services American use, how frequently they use them, how much is paid for the services, and who pays for them. It also will provide information on the types and costs of private health insurance available to the U.S. population. The survey is unparalleled in its degree of detail, as well as its ability to link medical care use, payments, and health insurance coverage to specific survey respondents and their families. It allows analysts to examine how individual and family characteristics, including the characteristics of their health insurance, affect medical care use and spending. This article discusses each of the MEPS components, focusing on design enhancements that have been made since the survey was last conducted nearly a decade ago.     

A longitudinal study of AIDS conversations between mothers and adolescents

This paper presents the results of a study on the introduced, free-ranging patas monkey population of Southwestern Puerto Rico (SWPR). It describes information on the population size, social group composition, diet, daily ranging patterns, and patas home range during a 3 year period. The patas monkey population in the study area consisted of approximately 120 individuals in four heterosexual groups and several all-male bands. Within their home ranges (26.8 km2), the population density was 4.47 individuals/km2. Home range size among the population's four heterosexual groups varied from 3.72 km2 to 15.39 km2, and minimum daily distance traveled ranged from 0.8-2.0 km. In general, the social structure and mating system of this population parallels what has been described for African populations. However, habitat use, ranging behavior, and the quality of intergroup interactions suggests that patas of this population exhibit territorial behavior.     

Image of industrial psychology among corporate executives.

89 executives attending a 1960 executive seminar of the American Management Association completed a 13 item questionnaire. "Almost twice as many executives stated that they would hire an industrial psychologist as compared with those who would decide against such a decision… . There are many executives still unconvinced that industrial psychology has any real worth at its present stage of development… . The areas of competence in which the industrial psychologist was judged to be most useful were morale, selection and training." (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Stability of aggression over time and generations.

In a study spanning 22 years, data were collected on the aggressiveness of over 600 subjects, their parents, and their children. Subjects who were the more aggressive 8-year-olds at the beginning of the study were discovered to be the more aggressive 30-year-olds at the end of the study. The stability of aggressive behavior was shown to be very similar to the stability of intellectual competence, especially for males. Early aggressiveness was predictive of later serious antisocial behavior, including criminal behavior, spouse abuse, traffic violations, and self-reported physical aggression. Furthermore, the stability of aggression across generations within a family when measured at comparable ages was even higher than the within individual stability across ages. It is concluded that, whatever its causes, aggression can be viewed as a persistent trait that may be influenced by situational variables but possesses substantial cross-situational constancy.

Rejection and depression: Prospective and contemporaneous analyses.

Explored the relationship of parental rejection during childhood and manifestations of depression both then and in young adulthood in 3 studies. In Study 1, 427 Ss were seen in 2 waves at the ages of 8 and 19 yrs. In the 1st wave, the parents of these Ss were also interviewed with a childrearing questionnaire that included a measure of rejection. In the 2nd wave, the Ss, then 19 yrs old, were administered the MMPI—D subscale. In the 2nd study, the contemporaneous relationship between maternal rejection and childhood depression was investigated. The identical measure of rejection used in the prospective study was administered to 245 mothers, and 4 measures of depression—peer ratings, self-ratings, teacher's ratings, and mother's ratings—were obtained for their children (mean age 10.11 yrs). The 3rd study, conducted with 508 mothers and their children (mean age 9.78 yrs) replicated the significant findings of the contemporaneous study. Findings support the hypothesis that deprivation in the generic sense ranging from the death of 1 or both parents to rejection or even parental disharmony is an etiological factor in adult depression.

Molecular mechanisms of G protein-coupled receptor signaling: role of G protein-coupled receptor kinases and arrestins in receptor desensitization and resensitization

Dynamic regulation of G protein-coupled receptor signaling demands a coordinated balance between mechanisms leading to the generation, turning off and re-establishment of agonist-mediated signals. G protein-coupled receptor kinases (GRKs) and arrestin proteins not only mediate agonist-dependent G protein-coupled receptor desensitization, but also initiate the internalization (sequestration) of activated receptors, a process leading to receptor resensitization. Studies on the specificity of beta-arrestin functions reveal a multiplicity of G protein-coupled receptor endocytic pathways and suggest that beta-arrestins might serve as adaptors specifically targeting receptors for dynamin-dependent clathrin-mediated endocytosis. Moreover, inactivation of the GRK2 gene in mice has lead to the discovery of an unexpected role of GRK2 in cardiac development, further emphasizing the pleiotropic function of GRKs and arrestins.
