The role of cluster B and C personality disturbance in the course of depression: a prospective study

The association between personality disturbance and depression has been noted consistently. Prospective tests of personality's impact on the course of depression, however, are lacking. In a sample of 159 undergraduates who experienced at least one prospective depressive episode, dimensional scores for clusters B and C personality disturbance were examined as prospective predictors of four indicators of the course of depression: severity, episode duration, symptomatic chronicity and number of episodes. Cluster C personality disturbance, characterized by anxious and fearful features, predicted depression chronicity. Cluster B, characterized by dramatic, emotional and/or erratic features, predicted severity and duration of depression. The findings are discussed in terms of the possible mechanisms underlying the effects of clusters B and C, as well as implications for future research.     

Prospective memory and pediatric traumatic brain injury: effects of cognitive demand.

This study investigated the effects of pediatric traumatic brain injury (TBI) on prospective memory. Fourteen children and 14 adolescents with TBI were compared with 25 and 23 noninjured children and adolescents, respectively. Based on a prefrontal model, the cognitive demand on the ongoing component of a prospective-memory task was manipulated. Overall, those with TBI had poorer prospective-memory performance than their noninjured peers. Performance was worse in a high cognitive-demand condition than a low, and younger children performed worse than adolescents. Decreases in performance from the low- to high-demand conditions were not significantly different between the two children's groups but were between the two adolescents' groups. Furthermore, the age and injury effects were reflected in the performances on executive function tests: the Self-ordered Pointing Task (SOPT), and the Stroop Color Word Interference Test. The Tower of London (TOL), which did not produce age or injury effects, was nevertheless found to be an important predictor of performance on the high-demand task in those with TBI. Although previous research has demonstrated impaired prospective memory performance in children with TBI, this study attempted to explain why this might occur, specifically that the prefrontal regions might be implicated.     

Mental representation of symbols as revealed by vocabulary errors in two bonobos (<Emphasis Type="Italic">Pan paniscus</Emphasis>)

Error analysis has been used in humans to detect implicit representations and categories in language use. The present study utilizes the same technique to report on mental representations and categories in symbol use from two bonobos (Pan paniscus). These bonobos have been shown in published reports to comprehend English at the level of a two-and-a-half year old child and to use a keyboard with over 200 visuographic symbols (lexigrams). In this study, vocabulary test errors from over 10 years of data revealed auditory, visual, and spatio-temporal generalizations (errors were more likely items that looked like sounded like, or were frequently associated with the sample item in space or in time), as well as hierarchical and conceptual categorizations. These error data, like those of humans, are a result of spontaneous responding rather than specific training and do not solely depend upon the sample mode (e.g. auditory similarity errors are not universally more frequent with an English sample, nor were visual similarity errors universally more frequent with a photograph sample). However, unlike humans, these bonobos do not make errors based on syntactical confusions (e.g. confusing semantically unrelated nouns), suggesting that they may not separate syntactical and semantic information. These data suggest that apes spontaneously create a complex, hierarchical, web of representations when exposed to a symbol system.

Relationships Among Self,Others, and Persecutors in Individuals With Persecutory Delusions: A Repertory Grid Analysis

The purpose of the current study was to examine the way individuals with persecutory delusions construe the self, others, and their main persecutor with reference to the constructs of malevolence and omnipotence, and examine the extent to which these interpersonal beliefs link to distress, self-esteem, and delusion conviction. Repertory grid methodology was used to explore interpersonal beliefs about malevolence and omnipotence in a sample (N = 30) of individuals with current persecutory delusions (mean age 36.4 years; 62% male and 53% White). Participants also completed measures of emotional distress (depression and anxiety) and self-esteem. The findings suggested that persecutors were construed as more omnipotent and malevolent than both the self and others; others in turn were construed as more omnipotent and malevolent than the self. Beliefs about self as powerful were associated with lower anxiety, depression, and higher self-esteem, and beliefs about persecutors’ omnipotence predicted delusion conviction. As with voices, the concepts of power/omnipotence and malevolence/benevolence appear to be important constructs when seeking to understand the relationship between individuals and their perceived persecutors. These findings support working therapeutically with negative schematic beliefs about self, others, and persecutors, which is consistent with a person-based cognitive therapy model of distressing psychosis.     

Early Pubertal Timing as a Vulnerability to Depression Symptoms: Differential Effects of Race and Sex

Robust evidence supports that girls and boys who experience early pubertal timing, maturing earlier than one’s peers, are vulnerable to developing symptoms of depression. However, it has yet to be clarified whether early pubertal timing confers vulnerability to African American as well as to Caucasian adolescents and whether this vulnerability is specific to depressive symptoms or can be generalized to symptoms of social anxiety. In previous studies, one race or one sex was examined in isolation or sample sizes were too small to examine racial differences. Our longitudinal study consisted of a sample of 223 adolescents (M_age?=?12.42, 54.3 % female, 50.2 % African American, and 49.8 % Caucasian). At baseline, depressive symptoms, social anxiety symptoms, and pubertal timing were assessed by self-report. Nine months later, we assessed depressive symptoms, social anxiety symptoms, body esteem, and stressful life events that occurred between baseline and follow-up. Analyses indicated that early pubertal timing interacted with stressful life events to predict increased symptoms of depression, but only for Caucasian girls and African American boys. Results were found to be specific to depressive symptoms and did not generalize to symptoms of social anxiety. Additionally, there was a significant positive indirect effect of pubertal timing on symptoms of depression through body esteem for Caucasian females.     

Translating the Human Right to Water and Sanitation into Public Policy Reform

The development of a human right to water and sanitation under international law has created an imperative to implement human rights in water and sanitation policy. Through forty-three interviews with informants in international institutions, national governments, and non-governmental organizations, this research examines interpretations of this new human right in global governance, national policy, and local practice. Exploring obstacles to the implementation of rights-based water and sanitation policy, the authors analyze the limitations of translating international human rights into local water and sanitation practice, concluding that system operators, utilities, and management boards remain largely unaffected by the changing public policy landscape for human rights realization. To understand the relevance of human rights standards to water and sanitation practitioners, this article frames a research agenda to ensure that human rights aspirations lead to public policy reforms and public health outcomes.     

Development ethics and evolving methods: a comparison of fair trade with the Millennium Villages Project

The motivations for rural and agricultural development in the twenty-first century are not different from previous centuries, but evolving technologies in the late twentieth century have altered many methods and institutional arrangements for accomplishing development. The internet has facilitated initiatives that in earlier decades would have required large, complex organizations in both donor and developing countries. We will compare the ethical and institutional strengths and weaknesses of two such initiatives in Malawi: a smallholder farmers organization involved in fair trade and the Millennium Village Project. These are two of a large array of institutions which are currently being used to benefit smallholder agricultural producers. We will examine their relative merits through the lenses of various ethical paradigms and show that the institutional arrangements of the two programs are complimentary in the evolution of agricultural trading systems linking the global north and south.     

The relationship between family‐of‐origin experiences and sexual satisfaction in married couples

This study examined the relationship between perceptions of family‐of‐origin experiences, sexual satisfaction and marital quality. The sample consisted of 3953 married couples who responded to the relationship evaluation. The results showed that more positive overall family‐of‐origin experiences and parent–child relationships were related to higher sexual satisfaction. Overall, family‐of‐origin experiences and parent–child relationships were predictive of higher sexual satisfaction; however, that relationship was significantly mediated by marital quality. There was a strong positive relationship between marital quality and sexual satisfaction. No major gender differences emerged from the findings. The results suggest that family‐of‐origin experiences play a key role in the sexual satisfaction of married couples, especially when mediated by marital quality, and should be considered in treatment, education and research.
