A dynamic Mover–Stayer model for recurrent event processes subject to resolution

In studies of affective disorder, individuals are often observed to experience recurrent symptomatic exacerbations warranting hospitalization. Interest may lie in modeling the occurrence of such exacerbations over time and identifying associated risk factors. In some patients, recurrent exacerbations are temporally clustered following disease onset, but cease to occur after a period of time. We develop a dynamic Mover–Stayer model in which a canonical binary variable associated with each event indicates whether the underlying disease has resolved. An individual whose disease process has not resolved will experience events following a standard point process model governed by a latent intensity. When the disease process resolves, the complete data intensity becomes zero and no further event will occur. An expectation–maximization algorithm is described for parametric and semiparametric model fitting based on a discrete time dynamic Mover–Stayer model and a latent intensity-based model of the underlying point process.     

Exploring Time Perspective in Greek Young Adults: Validation of the Zimbardo Time Perspective Inventory and Relationships with Mental Health Indicators

In this article we examine the factorial structure of the Greek version of the Zimbardo Time Perspective Inventory (ZTPI; Zimbardo and Boyd in J Personal Soc Psychol 77:1271–1288, 1999), in a sample of 337 university students, using principal axis factoring (PAF) with oblique rotation, and its dimensionality using parallel analysis. Moreover, we evaluate the internal consistency reliability, the convergent validity (through associations with mental health indicators such as dispositional optimism, self-esteem, trait anxiety, depression, and proactive coping), as well as discriminant, and differential validity of this instrument. The results indicated that the ZTPI had a 5-factor structure (past negative, past positive, present fatalistic, present hedonistic, future). Correlational analyses indicated that an aversive view of the past, and a fatalistic attitude toward life were positively and significantly associated with trait anxiety and depression, while they were negatively correlated with self-esteem, proactive coping, and dispositional optimism. Future time perspective was positively associated with proactive coping, whereas a positive attitude toward the past was negatively associated with depression and trait anxiety. Psychometric properties of the five ZTPI scales were satisfactory (Cronbach’s alphas ranging from .710 to .845), thus facilitating the robust investigation of time perspective in Greek speaking populations. However confirmatory factor analyses revealed that the “positive attitude toward the past” dimension might not be a good indicator of time perspective. We discuss the theoretical implications of these findings for future studies of time perspective.     

Job satisfaction and ‘welfare‐to‐work‘: is any job a good job for Australian single mothers?

This exploratory study sought to assess the job satisfaction of employed Australian single mothers who had mandatory employment participation requirements. In particular, we sought to identify the characteristics of the job and the individual that were closely associated with participant's job satisfaction. Self‐report data on job satisfaction, employment characteristics and parenting stress were collected from 155 employed single mothers. Participant job satisfaction was compared to female Australian population norms and linear regression analyses determined the job‐related and individual predictors of single mothers' job satisfaction. Findings from this exploratory study revealed that single mothers involved in a mandatory welfare‐to‐work program experienced significantly lower job satisfaction than the Australian female population. The individual variable, parental distress, negatively predicted each of the six job satisfaction domains while being employed on a casual basis was inversely associated with three domains (job security, work hours and overall job satisfaction). The Australian government purported that making the transition from welfare to work would improve wellbeing for program participants, under the assumption that ‘any job's a good job‘. However, the relatively low levels of job satisfaction experienced by single mothers in the current study provide little support for this assumption.     

Marginal methods for clustered longitudinal binary data with incomplete covariates

Many analyses for incomplete longitudinal data are directed to examining the impact of covariates on the marginal mean responses. We consider the setting in which longitudinal responses are collected from individuals nested within clusters. We discuss methods for assessing covariate effects on the mean and association parameters when covariates are incompletely observed. Weighted first and second order estimating equations are constructed to obtain consistent estimates of mean and association parameters when covariates are missing at random. Empirical studies demonstrate that estimators from the proposed method have negligible finite sample biases in moderate samples. An application to the National Alzheimer's Coordinating Center (NACC) Uniform Data Set (UDS) demonstrates the utility of the proposed method.     

At Home With Derek Jarman

Home is never only of the present. A sense of personal robustness and sometimes political resistance can emerge through a tacking back and forth between homes past and present—especially for those who felt and feel socially or culturally marginalized. We see this vividly in the way the filmmaker Derek Jarman created his home and garden at Prospect Cottage at Dungeness on the Kent coast in the context of his failing health. In this piece I show how formative homes, homes of early adulthood, and aspirations for a different kind of home life inflect the way Jarman lived at Prospect in his here and now. This is about the rolling together of different ages and experiences in ways that can give a sense of endurance in uncertain times.     

Caregiver–Youth Communication about Sex in South Africa: The Role of Maternal Child Sexual Abuse History

Much of the research on child sexual abuse focuses on negative outcomes. This brief report explores a potentially protective parenting behavior among black South African female caregivers with and without a child sexual abuse history. Using cross-sectional baseline data, we hypothesized that caregiver child sexual abuse history would be positively associated with caregiver–youth sex communication and this relationship would be strongest for girls. Youth whose caregiver experienced child sexual abuse were more likely to report communicating with their caregiver about sex than youth whose caregivers did not experience child sexual abuse; however, this relation did not hold for caregiver reported communication. Child sexual abuse survivors’ ability and decision to discuss sex with their youth has the potential to protect youth from sexual risk and demonstrates resilience among a group rarely acknowledged for positive parenting practices.     

A Review of: “Producing Sperm Sperm Counts: Overcome by Man's Most Precious Fluid. By Lisa Jean Moore.”

This paper offers a preliminary conceptualization of the psychological structure of AIDS‐related attitudes among American adults and describes some of the social and psychological factors that affect those attitudes. Data were collected first from participants in focus groups in five U.S. cities and then from respondents in a national telephone survey. Two major psychological dimensions of attitudes were observed consistently. The first dimension, labeled COERCION/COMPASSION, includes judgments about the extent to which AIDS is viewed as highly contagious and requiring containment, through coercion if necessary. It also includes attributions of blame to people with AIDS. The second dimension, PRAGMATISM/MORALISM, includes judgments about the extent to which AIDS is viewed as controllable through research, public education and governmental sponsorship of behavior‐change programs. The two attitude dimensions are not highly correlated. Regression analyses suggest that the two dimensions have different social and psychological antecedents and that these antecedents differ between White and Black Americans. Using the two factors, a tentative typology of responses to the AIDS epidemic is presented. Implications for AIDS education and policy are discussed.     

Subnational migration in the United Kingdom: producing a consistent time series using a combination of available data and estimates

There is no single framework in place in the United Kingdom for collating and harmonizing the data on migration taking place between the subnational administrative units that constitute the home nations, together with the flows of international migration between these areas and the ‘rest of the world’. This paper proposes the construction of complete matrices of subnational migration statistics on an annual basis which can then be used to monitor migration trends throughout the UK in a comprehensive manner. The paper reviews how various ‘known’ flows are estimated by the national statistics agencies and develops estimates to fill in the gaps in the matrices. It then looks at changing patterns of migration in the UK between 2001/2002 and 2010/2011, showing that migration exhibits most activity in the middle of the decade. Flows within the home nations are the most consistent over time, while the patterns of international migration and migration across the borders of the home nations exhibit more substantial change. The latter flows, although relatively small in magnitude, have not previously been studied at the subnational level in any detail. Patterns of subnational internal and international net migration are found to be negatively correlated.     

Long-term effects of forearm support: computer users working at conventional desks

Recent research has demonstrated that forearm support might be preferable to working in the traditional "floating" posture for computer users. A previous field study in a call centre reported a significant decrease in discomfort following 12 weeks of using a conventional desk for forearm support. The aim of this follow up study was to determine the long-term effect (21 months post intervention) of forearm support on reported musculoskeletal discomfort in the previous sample of intensive computer users. METHODS: The follow-up sample consisted of 33 females and 2 males (59% of original group). Data were collected via self-report questionnaires and workstation assessments. RESULTS: Despite a significant reduction in discomfort for most body regions following the initial intervention, the only significant decrease in discomfort over 21 months was for the neck. Reported discomfort for all other body regions had decreased, apart from the shoulder in which there was a reported increase in discomfort. The results of this follow up study indicate that forearm support has a positive effect on the reduction of neck discomfort. The increase in shoulder discomfort indicates that a concave desk may be preferable to the conventional desk if the forearm support posture is to be adopted.     

The role of psychiatric nurse faculty in establishing a campus suicide prevention program

Suicide among college students has received increased national attention over the past few decades, partly due to the publicity regarding high-profile suicide events on college campuses throughout the United States and its territories. Currently, suicide is identified as the second-leading cause of death in college students. Due to federal legislation such as the Garrett Lee Smith Memorial Act of 2004, many college campuses have been able to establish suicide prevention programs. This article describes how a psychiatric nurse faculty member successfully established a comprehensive suicide prevention program that was initially supported by grant funds from the Garrett Lee Smith Memorial Act.
