Discussions of birth rates in less developed countries (LDC’s) are almost always couched in terms of income per-capita or per-consumer-equivalent. A decrease in population growth rate is said to lead to a higher per-capita income (PCI) than would occur with a higher birth rate, and therefore a lower birth rate is advocated. This runs the danger of choosing a course of action that people really do not want. A static analysis of a PCI criterion leads to an optimum which is quite unacceptable. One can raise the PCI of any given group by getting rid of all small sub-groups that have a lower PCI. Static analysis is not directly relevant to those problems of LDC’s, because the relevant control variable is the birth rate. This paper explores some of the ramifications of different birth rates. The general conclusion is that per-capita income alone cannot be a satisfactory criterion for a rational national natality policy. At best it can be but one factor to be taken into consideration in such a policy decision. 相似文献

Abstract Numerous tools have been developed that attempt to measure work-related stress and working conditions, but few practical instruments in the literature have been found to have a reliable psychometric factor structure. In the UK, the Health and Safety Executive (HSE) Management Standards (MS) Indicator Tool is increasingly used by organizations to monitor working conditions that can lead to stress. In Health and Safety Executive (2004), a factor analysis was conducted demonstrating the reliability of the scales. However, the authors acknowledged that direct reassessment of the same factor structure was impossible as the questionnaire was split into two separate modules for data collection. Furthermore, the tool is designed to enable comparisons between as well as within organizations to take place, yet reliability has only previously been tested at the individual level. The current study is the first to examine the factor structure of the HSE MS Indicator Tool using organizational-level data. Data collected from 39 UK organizations (N=26,382) was used to perform a first-order Confirmatory Factor Analysis (CFA) on the original 35-item seven-factor measurement scale. The results showed an acceptable fit to the data for the instrument. A second-order CFA was also performed to test if the Indicator Tool contains a higher order uni-dimensional measure of work-related stress. These findings also revealed an acceptable fit to the data, suggesting that it may be possible to derive a single measure of work-related stress. Normative data comprising tables of percentiles from the organizational data are provided to enable employers to compare their organizational averages against national benchmarks. 相似文献

This paper reviews basic components of the initial screening interview for applicants to treatment programs for pathological gamblers. The therapeutic potential of the interview is seen as primary and the collection of information follows an initial period of unstructured exploration of feelings. Specific information needed in making an admission decision is reviewed including items related to the gambling addiction, to family, employment, health, co-addiction, attitude, and demographics. Some items of information required by the client are reviewed. Criteria for acceptance or rejection are mentioned throughout. The rationale for various items of policy is reviewed briefly in a number of situations. 相似文献

The theory of the low-level equilibrium trap asserts that an increase in income stimulates population growth sufficiently so that the additional people ‘eat up’ the ‘surplus’ over subsistence, and hence drive the level of income back to subsistence. Originally the theory referred primarily to mortality, but nowadays its application is to fertility. In the long-run equilibrium context in which the theory is ordinarily presented, the fact that the long-run elasticity of fertility with respect to income is negative in less developed countries fatally contradicts the accepted version of the trap. But to give every chance for trap theory to be meaningful, the paper presents a period-by-period analysis, embodying larger-than-observed positive elasticities during the early years and the logically necessary counterbalancing negative elasticities during the later years. These elasticities are combined with consumption and production figures for various age groups to estimate the effect in each year after the windfall, and altogether. The results show that even under assumptions not charitable to the conclusion of this paper, additional children do not even come close to ‘eating up’ the increase in income which induced their births, so that the trap theory is falsified. 相似文献

Lesbian, gay, bisexual, transgender, and queer (LGBTQ) people have become a familiar presence on the media landscape. For more than half a century, scholars have examined the importance of this recognition. In this article, I extend the work of British sociologist Ken Plummer to argue that key narratives have endured in discussions of LGBTQ media. These narratives include the victim, the community, the militant/queer, and the assimilationist. In addition, this paper points toward new directions for analysis and discussion; I argue that future research should take a more nuanced approach by examining overlaps and tensions among these stories. 相似文献

AbstractObjective: To develop and validate a scale measuring health beliefs about UV in cloudy climates that may impact UV exposure behaviors. Participants: Students at a large university in Oregon completed pilot (N?=?115) and final (N?=?335) scales online March–July, 2016. Five participants underwent cognitive interviews. Methods: Expert feedback, cognitive interviews, and pilot data guided item development and refinement. We conducted factor analysis and invariance testing. Results: The final four-factor model fit well (χ2?=?37.97, df?=?37, RMSEA?=?0.000, CFI?=?1.000). HBAU subscales are Sunscreen Toxicity, Seasonal Effects, Health Benefits of Tanning, and Tanning Through the Winter. Invariance testing supported strong invariance across sex and tanning status. Conclusion: The HBAU measures beliefs that encourage UV exposure and discourage protection (eg, the belief that sunscreen ingredients are toxic). This scale will enable more comprehensive measurement of cognitive predictors of UV exposure for student health, clinical, and research purposes. 相似文献

Nonheterosexuals experience oppression and discrimination that affect personal development on all levels. An increased awareness of sexual identity development could create more inclusive sexual identity models, better understanding for counselor educators, and better training for counselors on issues of sexual identity. The purpose of this study was to identify the life experiences that influence sexual identity in women who love women. This study required that participants attach meaning to sexual identity formation. From the data collected, four themes emerged: I was just different, information seeking, view of self as a woman within the context of culture, and contextual relationships. Findings of this study did not support a stage model of sexual identity development. Instead, this study supported the view that sexual identity is fluid and strongly related to relationships with peer groups. 相似文献
