Longitudinal Perspective (longitudinal + perspective)
Selected AbstractsWomen's Scientific Employment and Family Formation: A Longitudinal PerspectiveGENDER, WORK & ORGANISATION, Issue 6 2008Louisa Blackwell We focus here on the retention of highly qualified women scientists in science-based employment in England and Wales. Using linked Census records from the Longitudinal Study 1971,1991 we show that women's education and employment rates in science, engineering and technology increased somewhat, although some fields show persistently low representation. We then compare retention in employing women with health-related degrees with that of women with degrees in science, engineering and technology, showing that the latter group has markedly lower retention rates. Those who stay on in science-based employment have children later than other types of graduate and their rates of non-motherhood are higher. Four-fifths of women in health-related occupations were mothers, compared to only two-fifths in science, engineering and technology. Our findings have implications for policymakers who wish to make best use of the knowledge base: attention should be paid to retention, as well as the more usual focus on qualifications and recruitment. The findings also suggest the potential for institutionally based theories to explain why highly qualified women have such low retention rates in science-based employment. [source] Family Adversity, Positive Peer Relationships, and Children's Externalizing Behavior: A Longitudinal Perspective on Risk and ResilienceCHILD DEVELOPMENT, Issue 4 2002Michael M. Criss Peer acceptance and friendships were examined as moderators in the link between family adversity and child externalizing behavioral problems. Data on family adversity (i.e., ecological disadvantage, violent marital conflict, and harsh discipline) and child temperament and social information processing were collected during home visits from 585 families with 5,year,old children. Children's peer acceptance, friendship, and friends' aggressiveness were assessed with sociometric methods in kindergarten and grade 1. Teachers provided ratings of children's externalizing behavior problems in grade 2. Peer acceptance served as a moderator for all three measures of family adversity, and friendship served as a moderator for harsh discipline. Examination of regression slopes indicated that family adversity was not significantly associated with child externalizing behavior at high levels of positive peer relationships. These moderating effects generally were not qualified by child gender, ethnicity, or friends' aggressiveness, nor were they accounted for by child temperament or social information,processing patterns. The need for process,oriented studies of risk and protective factors is stressed. [source] The Historical Geographies of Showing Livestock: a Case Study of the Perth Royal Show, Western AustraliaGEOGRAPHICAL RESEARCH, Issue 3 2010RICHARD YARWOOD Abstract This paper examines changes in the entries of livestock to competitions at the Perth Royal Show in the course of the twentieth century. It identifies trends in the showing of animals at the Show and explains these with reference to the wider geographies of state and national agricultural change in Western Australia (WA). In doing so, it provides a longitudinal perspective on the socioeconomic contexts of farming in WA and identifies some of the key cultural and economic drivers that have influenced livestock farming in that locality. In turn, these findings contribute to wider understandings of the global countryside and of the imagined ruralities that exist within and beyond the spaces of showgrounds. [source] Repartnering and (Re)employment: Strategies to Cope With the Economic Consequences of Partnership DissolutionJOURNAL OF MARRIAGE AND FAMILY, Issue 5 2009Mieke Jansen The economic consequences of a partnership dissolution have been described consistently in the research literature. For women all studies indicate severe financial losses, whereas men do not experience income decreases to the same extent. This article focuses on the 2 main strategies to cope with the economic consequences of a separation: repartnering and (re)employment. Using the European Community Household Panel Study we analyzed a sample of 66,292 individuals observed in a relationship of whom 4,925 subsequently separated and assessed the (relative) effect of both strategies in a cross-national longitudinal perspective. Where men do not benefit financially from cohabiting with a new partner, repartnering proves to outweigh the benefits of reentering the labor force or increasing the working hours for most women. This especially applies to mothers. [source] Supply's Growing Status and Influence: A Sixteen-Year PerspectiveJOURNAL OF SUPPLY CHAIN MANAGEMENT, Issue 2 2006P. Fraser Johnson SUMMARY The recent completion of a major survey of large North American supply organizations in 2003 permits a longitudinal perspective on supply roles and responsibilities over a 16-year period. The latest survey complements two earlier studies in 1987 and 1995. All three surveys counted at least 280 responding large North American supply organizations, thereby providing a valuable opportunity to examine trends and changes over time. Major areas of investigation for respondents in both the manufacturing and services sectors include supply organizational structure, supply chain responsibilities, and chief purchasing officer (CPO) reporting line, title and background. This research provides solid evidence that in both manufacturing and services, today's CPOs have greater responsibilities, report higher in the organization and carry more significant titles than their predecessors. The conclusion is that, at least in large North American companies, supply has grown substantially in corporate status and influence since 1987, a particularly welcome discovery. [source] Determinants of new firm success,PAPERS IN REGIONAL SCIENCE, Issue 2 2000Veronique A.J.M. Schutjens New firm growth; success determinants; starter typology Abstract. The differences between new firms, even the differences present right at the start, may affect their life course and success over time. This article addresses the determinants of success of Dutch start-ups from a longitudinal perspective. After an overview of the literature on both the definition of success and the success factors of new firms we test how new firm characteristics relate to firm growth in number of employees using a panel of nearly 2,000 firms. In addition to a large firm size right from the start, good preparation, having a business partner, and some years in salaried employment also enhance firm growth. Based on these success determinants we construct a typology of starters that may be used to predict future growth chances. [source] Sibling relationships in adolescence: Learning and growing togetherPERSONAL RELATIONSHIPS, Issue 1 2005Patricia Noller In this article, I discuss the reasons for my interest in sibling relationships, and showcase studies on sibling relationships in adolescence carried out with my colleagues and students, in the context of the broader literature on sibling relationships. Our studies have focused on a number of important issues concerned with sibling relationships. First, I report on the associations between sibling relationships and other family relationships and the ways that the various family relationships affect each other. Second, I report a study of sibling relationships in the context of parental separation and divorce and show that sibling relationships in these families are more likely to be high in both warmth and hostility than is true for relationships in 2-parent families. Third, I report on several data sets showing an association between the quality of sibling relationships and adolescent adjustment and the link between differential parenting, adolescent adjustment, and the quality of the sibling relationship. Fourth, I report on a study of comparison and competition in sibling relationships and the associations between sibling relationship quality and reactions to being outperformed by a sibling. Finally, I discuss possible future directions for research on sibling relationships, including the importance of multimethod studies and a longitudinal perspective. [source] Contraception and pregnancy then and now: Examining the experiences of a cohort of mid-age Australian womenAUSTRALIAN AND NEW ZEALAND JOURNAL OF OBSTETRICS AND GYNAECOLOGY, Issue 4 2009Christine READ Background: More than 50% of women who have an unplanned pregnancy report using a contraceptive method. Since the launch of the pill 50 years ago, a number of cross-sectional surveys have examined contraceptive use in the Australian context. There is, however, little data on contraceptive use and efficacy over a woman's reproductive years. Aim: To determine the pattern of contraceptive use of Australian women over their reproductive lifespan, with particular emphasis on the relationship between contraceptive use and pregnancy. Method: One thousand women from the mid-age cohort of the Australian Women's Longitudinal Study were invited to participate in the Family Planning survey by completing a questionnaire about their reproductive histories. Results: Completed questionnaires were received for 812 women. The contraceptive pill was the most commonly ever used contraceptive method at 94% and also the most commonly used method prior to all pregnancies. Contraceptive failure increased with increasing gravidity; 11.4% with the first pregnancy to 23.0% with the fourth pregnancy, while 28.8% of the respondents reported an ,accidental' pregnancy due to stopping contraception for reasons such as concern about long-term effects and media stories. Conclusions: While surveys indicate that 66,70% of Australian women use a contraceptive method, more than half of unplanned pregnancies apparently occur in women using contraception. The modern Australian woman, in common with her predecessors, still faces significant challenges in her fertility management. This survey provides a longitudinal perspective on contraceptive use in relation to pregnancy and highlights the issue of efficacy of contraceptives in real-life situations. [source] Estimating HIV Incidence Based on Combined Prevalence TestingBIOMETRICS, Issue 1 2010Raji Balasubramanian Summary Knowledge of incidence rates of HIV and other infectious diseases is important in evaluating the state of an epidemic as well as for designing interventional studies. Estimation of disease incidence from longitudinal studies can be expensive and time consuming. Alternatively, Janssen et al. (1998,,Journal of the American Medical Association,280, 42,48) proposed the estimation of HIV incidence at a single point in time based on the combined use of a standard and "detuned" antibody assay. This article frames the problem from a longitudinal perspective, from which the maximum likelihood estimator of incidence is determined and compared with the Janssen estimator. The formulation also allows estimation for general situations, including different batteries of tests among subjects, inclusion of covariates, and a comparative evaluation of different test batteries to help guide study design. The methods are illustrated with data from an HIV interventional trial and a seroprevalence survey recently conducted in Botswana. [source] | |||||||||||||
