The Relation Between Eating- and Weight-Related Disturbances and Depression in Adolescence: A Review

Depression often emerges during adolescence and persists into adulthood. Thus, it is critical to study risk factors that contribute to the development of depression in adolescence. One set of risk factors that has been recently studied in adolescent depression research is eating- and weight-related disturbances (EWRDs). EWRDs encompass negative cognitions related to one’s body or physical appearance, negative attitudes toward eating, and unhealthy weight control behaviors. However, there have been no comprehensive reviews of EWRDs and depression research that are contextualized within developmental frameworks of adolescent depression. Thus, this review will summarize research findings on the relation between EWRDs and depression in adolescence using a cognitive vulnerability developmental framework. First, a brief overview of epidemiological findings on depression is provided in order to highlight the importance of examining depression in adolescence. Second, a cognitive vulnerability developmental framework that can be used to conceptualize depression in adolescence is described. Next, theories and findings on EWRDs and depression in adolescence are summarized within this framework. Research limitations and suggestions for future research are provided. Finally, implications of this review related to the assessment, intervention, and prevention of depression in adolescence are provided.     

Event valence and estimates of own, average person's, and randomly chosen person's risk

People typically believe they have a lower likelihood of experiencing negative events and a greater likelihood of experiencing positive events than does the average person. This effect is greater for negative than positive events. It has been proposed that this is a by-product of a tendency for estimates of the average person's likelihood to increase with the size of the group concerned. If so, event valence should affect estimates of the average person's likelihood, but not estimates of one's own likelihood or estimates of the likelihood of a person selected at random. These predictions were tested for a single event using a student sample (N = 113). Results were not in accord with the proposal. An explanation in terms of motivational processes is offered instead.     

Computer‐assisted learning for adults with profound multiple disabilities

Five adults with profound physical and intellectual disabilities were taught to respond to photographs of preferences embedded in Microsoft PowerPoint (Microsoft, 1997 ) presentations by operating microswitches that functioned as mouse clicks. Rate of responding was generally correlated with changes in types of presentation, although variability in rate was often high, and session durations were quite short. Two participants showed substantial increases in responding when fitted with switches that were easier to manipulate. This exploratory study demonstrates that people with extremely limited physical and cognitive abilities can be taught to operate switches that produce changes in visual arrays on a computer screen and sometimes differentially so. Implications for responding to photographic representations of preferences, rather than the tangible preferences themselves, are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

Immigrant Asian youth and cultural-identity challenges: implications for pastoral counseling practice

Immigrant Asian youth's five cultural-identity stages and their challenges are examined. Theological significance in working with immigrant Asian youth is also the focus of this article. The essay concludes with implications for pastoral counseling practice, with respect to culturally sensitive effective therapeutic treatment of immigrant Asian youth and their families.     

A meta-analysis of the antecedents and consequences of pay level satisfaction

This study reports results from a meta-analysis of 28 correlates of pay level satisfaction involving 240 samples from 203 studies conducted over the past 35 years. Results are presented in 4 categories: primary determinants, antecedents, correlates, and outcomes of pay satisfaction. The authors controlled for pay in examining relations between correlates and pay level satisfaction, as suggested by theory and when primary studies were available to do so. The authors found support for many of the relations suggested by a theoretical model and also note some limitations in the research that has tested this model. The authors recommend changes and additions to the model and suggest additional primary research in specific areas.     

"Silent" metaplasticity of the late phase of long-term potentiation requires protein phosphatases

The late phase of long-term potentiation (L-LTP) is correlated with some types of long-term memory, but the mechanisms by which L-LTP is modulated by prior synaptic activity are undefined. Activation of protein phosphatases by low-frequency stimulation (LFS) given before induction of L-LTP may significantly modify L-LTP. Using cellular electrophysiological recording methods in mouse hippocampal slices, we show that LFS given before induction of L-LTP inhibited L-LTP in an activity-dependent manner without affecting either basal synaptic strength or the early phase of LTP (E-LTP). This anterograde inhibitory effect of LFS was persistent, required N-methyl-D-aspartate (NMDA) receptor activation, and was blocked by inhibitors of protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A). These data indicate that certain patterns of LFS can activate PP1 and/or PP2A, and that long-lasting activation of these phosphatases by prior LFS can suppress the subsequent expression of L-LTP without affecting E-LTP. Because this inhibition of L-LTP is caused by prior synaptic activity that, alone, produced no net effect on synaptic efficacy, we suggest that this is a “silent” form of metaplasticity that may influence long-term information storage by modulating the capacity of synapses to express L-LTP after repeated bouts of activity.     

Semi-Post algebras

In this paper, semi-Post algebras are introduced and investigated. The generalized Post algebras are subcases of semi-Post algebras. The so called primitive Post constants constitute an arbitrary partially ordered set, not necessarily connected as in the case of the generalized Post algebras examined in [3]. By this generalization, semi-Post products can be defined. It is also shown that the class of all semi-Post algebras is closed under these products and that every semi-Post algebra is a semi-Post product of some generalized Post algebras.     

Social Support from Family and Friends and Subjective Well-Being of Older African Americans

This study examines the impact of informal social support from family and friends on the well-being of older African Americans. Analyses are based on a nationally representative sample of older African Americans from the National Survey of American Life (n = 837). Three measures of well-being are examined: life satisfaction, happiness and self-esteem. The social support variables include frequency of contact with family and friends, subjective closeness with family and friends, and negative interactions with family. Results indicate that family contact is positively correlated with life satisfaction. Subjective closeness with family is associated with life satisfaction and happiness and both subjective closeness with friends and negative interaction with family are associated with happiness and self-esteem. There are also significant interactions between family closeness and family contact for life satisfaction, as well as friendship closeness and negative interaction with family for happiness. Overall, our study finds that family and friend relationships make unique contributions to the well-being of older African Americans. Qualitative aspects of family and friend support networks (i.e., subjective closeness, negative interactions) are more important than are structural aspects (i.e., frequency of contact). Our analysis verify that relationships with family members can both enhance and be detrimental to well-being. The findings are discussed in relation to prior research on social support and negative interaction and their unique associations with well-being among older African Americans.
