Gerotranscendence theory is reviewed regarding its content, development, diffusion, impact, empirical results, and ontology. Gerotranscendence theory describes a “natural” alteration of consciousness in old age leading to “wisdom” and a qualitative break with a mid-life rational and materialist world-view. According to the theory, gerotranscendence is obstructed by a lack of alternative values and roles in old age in Western societies. Theoretically and in clinical practice, gerotranscendence theory has been linked to psychoanalysis. It is concluded that gerotranscendence theory is empirically weak, has parallels in the New Age movement as well as in romantic Orientalism, and can be understood as an attempt to re-enchant aging.  相似文献

Technology-based spin-offs from academic institutions and private corporations represent an important proportion of young innovation-oriented ventures. They encounter specific starting conditions in terms of their core technology, the composition of the founding team, and the critical junctures during their establishment. This study analyses the state-of-the-art in quantitative empirical research on factors impacting the development of these types of firms. We present findings of both research fields and discuss them critically. Methodological and measurement issues receive particular attention in our analysis. Based on the literature review we identify factors impacting the development of both types of firms. Additionally we expose gaps in past and current research on academic and corporate spin-offs and suggest interesting opportunities for future research. Methodological shortcomings of existing studies are discussed. We derive implications for research on academic and corporate spin-offs and for the management of these types of firms.  相似文献

Multiplicative and additive models of job and life satisfaction   总被引:1,自引:0,他引:1  
Overall job satisfaction has often been specified as a multiplicative function of the satisfaction with and the perceived importance of more specific job facets. Correspondingly, overall life satisfaction may be conceptualized as a multiplicative function of satisfaction with and importance of various life domains. So far empirical research has tended to reject the multiplicative model. Correcting for the effects of acquiescence bias and using more appropriate statistical methods than in most previous studies, the multiplicative model is here shown to fit the job satisfaction data significantly better than alternative additive models. For the relationships between life domains and overall life satisfaction, however, the multiplicative model is again rejected. Possible reasons for these diverging results are discussed.  相似文献

A sample of 3,201 Danes was subjected to personal interviews in which they were asked to state their preferences for risk-reducing health care interventions based on information on absolute risk reduction (ARR) and relative risk reduction (RRR). The aim of the study was to measure the relative weighting of different types of risk information under various circumstances. The effect of presenting questions, and of explicitly formulating RRR, was analyzed. A preference for increases in RRR was demonstrated. There was a stronger inclination to choose the intervention that offered the highest RRR if RRR was explicitly stated. Individuals with more than 10 years of schooling also demonstrated a preference for increased ARR, but only when facing individually framed choices. In a social choice context, preferences for RRR remained intact, but the magnitude of ARR had no impact on choices. Results imply that social framing may induce a propensity to prefer interventions that target high-risk populations. Those respondents who had received < or = 10 years of schooling demonstrated preferences for RRR but not ARR, and no impact of social framing was observed.  相似文献

In recent years, researchers have paid increasing attention to the issue of care in the new types of family and partner relationships. The aim of this study is to examine expectations and attitudes concerning care among elderly people in LAT (Living Apart Together)- relationships in Sweden, that is, people who have a long-term intimate relationship, but who do not share a common home. Questionnaires were completed by 116 elderly people in LAT-relationships. Partners are ranked as the main providers of care, especially by men, but there is considerable variation in the answers. This seems to be principally related to the degree of flexibility in this type of relationship. Some individuals see a LAT-relationship as a marriage-like relationship, while others see it primarily as a type of relationship that guarantees them the possibility of maintaining their own independent way of life.  相似文献

This article discusses special category housing for homeless addicts, based on case studies of two different housing programmes and using both qualitative and quantitative data. The staff and residents were interviewed about their experiences of the programmes. Longitudinal data were collected on various indicators of substance misuse and the frequency of contact with the social services at different levels. Our findings show that special category housing has positive direct effects on the housing stability of the residents and their feelings regarding their quality of life, but not on their substance misuse. However, the increased housing stability seems to be more a direct effect of their staying on the programme, rather than a long-term effect. Furthermore, although their quality of life improves, the residents still experience a lack of belonging and feel that their lives lack meaningful content. The choice of special category housing as an intervention model thus seems to perpetuate rather than prevent social exclusion and can possibly be described as an expression of 'institutionalised resignation'.  相似文献

The percentage of breakdowns in marriages, cohabitations and civil partnerships is increasing in the Western world, resulting in questions of child custody. In Norway and other Western countries, there is little knowledge of the support system's work in child custody cases. This article focuses on the assessments Norwegian child welfare service employees conduct in 37 cases about child custody. We explain why they sometimes conduct investigations of reports and at other times do not.

‘Street-level bureaucracy’ is the theoretical reference framework for interpreting the interviews. Assessments and decisions of the child welfare service in custody cases vary from one service to another. It is relatively difficult to predict whether the notifications will be investigated or dropped. Decisions are the result of a jigsaw puzzle of risk assessment, interpretations of legislation, cooperative procedures and an understanding of the county social welfare board. Notifications concerning violence and notifications from family counselling offices stand out since generally they result in investigations.

Child welfare services' handling of notifications regarding custody questions is challenging as these cases are in the grey zone between the Children Act and the Child Welfare Act. Child welfare workers want clearer guidelines for the cases on which they are to work. However, new rules cannot replace the professional and ethical assessments the child welfare service workers have to make in each individual case.  相似文献

The network choice revenue management problem models customers as choosing from an offer set, and the firm decides the best subset to offer at any given moment to maximize expected revenue. The resulting dynamic program for the firm is intractable and approximated by a deterministic linear program called the CDLP which has an exponential number of columns. However, under the choice‐set paradigm when the segment consideration sets overlap, the CDLP is difficult to solve. Column generation has been proposed but finding an entering column has been shown to be NP‐hard. In this study, starting with a concave program formulation called SDCP that is based on segment‐level consideration sets, we add a class of constraints called product constraints (σPC), that project onto subsets of intersections. In addition, we propose a natural direct tightening of the SDCP called , and compare the performance of both methods on the benchmark data sets in the literature. In our computational testing on the data sets, 2PC achieves the CDLP value at a fraction of the CPU time taken by column generation. For a large network our 2PC procedure runs under 70 seconds to come within 0.02% of the CDLP value, while column generation takes around 1 hour; for an even larger network with 68 legs, column generation does not converge even in 10 hours for most of the scenarios while 2PC runs under 9 minutes. Thus we believe our approach is very promising for quickly approximating CDLP when segment consideration sets overlap and the consideration sets themselves are relatively small.  相似文献
