This article outlines the development of a tool to assess psychosocial needs in U.S. Air Force (USAF) units. Instrument development began with the construction of an item taxonomy, pretesting procedures (Q-sort; cognitive interviews), and a pilot web survey to document internal consistency and test-retest reliability, followed by two large-scale Web surveys to derive a viable factor structure. Because certain items (e.g., child care) were not relevant to all respondents, multiple imputations to replace missing values were necessary before factor analyses could proceed. Exploratory factor analyses of data from the first Web survey revealed an eight-factor solution; and data from the second Web survey confirmed that the eight-factor solution could be replicated on an independent sample. Developed in accordance with psychometric principles, the final assessment tool tapped a range of psychosocial factors spanning quality of work life, community life, family functioning, and personal well-being. 相似文献

It is usually difficult to undercool Ti–Al alloys on account of their high reactivity in the liquid state. This results in a serious scarcity of information on their thermophysical properties in the metastable state. Here, we report on the surface tension of a liquid Ti–Al alloy under high undercooling condition. By using the electromagnetic levitation technique, a maximum undercooling of 324 K (0.19 T L) was achieved for liquid Ti-51 at.% Al alloy. The surface tension of this alloy, which was determined over a broad temperature range 1429–2040 K, increases linearly with the enhancement of undercooling. The experimental value of the surface tension at the liquidus temperature of 1753 K is 1.094 N m?1 and its temperature coefficient is ?1.422 × 10?4 N m?1 K?1. The viscosity, solute diffusion coefficient and Marangoni number of this liquid Ti–Al alloy are also derived from the measured surface tension. 相似文献

Abstract Since the early 1990s the Singapore government has been taking a more liberal stance on controversial issues such as gay rights, embryonic stem cell research and the gaming industry. My paper analyses the Singapore state's utilitarian justification and its authoritarian enactment of these liberal policies. The first part looks at the underlying motivation for the cultural makeover. I frame my analysis around the reaction of the Singapore Christian community to these developments. I focus on the criticisms of the state's ‘liberal’ agenda made by Evangelicals, and describe how the People's Action Party (PAP) regime has defended these policies on utilitarian grounds. The first part ends with a comparative analysis of how the ‘cultural war’ debate was played out in Singapore and the USA. In the second part I examine the procedural aspects of this cultural experimentation. I start with a review of Singapore's political reform. I show that civil society in Singapore has attained a new openness. Yet there remain constraints, leading critics to label the PAP-led government as a ‘soft-authoritarian’ democracy. Singapore's cultural policies, I explain, are essentially an ‘elitist’ state-engineered top-down development. This is in contrast to the experience in the USA, where grassroots activists exercise tangible bottom-up influence on how cultural contests are resolved. My main thesis is to argue that Singapore's recent cultural liberalisation is guided by social–economic expediency notwithstanding the alleged moral risks, and that these are state-commanded liberal experimentations, imposed by the ruling elite upon a constituency that is still largely conservative in moral outlook. 相似文献

The relation of mothers’ attitudes on the effects of maternal employment on children, psychological well-being, sensitivity of the mother, and children’s socioemotional development were examined in mothers who worked full time (consistently) and mothers who were unemployed during their children’s early years of growth from 6 months of age. Longitudinal observations of 1,213 mothers and children from age 1 to 36 months from the National Institute of Child Health and Human Development (NICHD) Study of Early Child Care were analyzed using structural equation models. Mothers and children benefited when maternal attitudes were consistent with the mothers’ actual employment status. Among consistently employed mothers, those with positive attitudes about employment had better psychological well-being. When mothers who were unemployed, they believed that maternal employment would have positive consequences for their children’s development, they preferred working outside home and they were more likely to show a low level of psychological well-being and poor quality of mother-child relation. Additionally, maternal well-being mediated the relation between a mother’s attitudes and a child’s social competence. For both groups, better psychological well-being of mothers was positively related to better child’s socioemotional outcome. Maternal sensitivity, however, did not mediate the relation between maternal attitudes and child’s social outcomes. The findings shed light on the need for a sensitive measure of characterizing mothers who work versus those who stay at home in order to better understand the effects on a child’s development. 相似文献

ObjectiveThe purpose of this study was to clarify the immediate and sustained effects of an acute bout of exercise on the planning aspects of executive function.DesignThis study used a 2 × 4 true experimental design.MethodForty participants were randomly assigned to either the exercise or control groups and completed the Tower of London task prior to, immediately following, 30 min after, and 60 min after cessation of a 30 min, moderate intensity cycling exercise.ResultsAcute exercise positively impacted the total move score, which reflects planning efficiency, immediately after the cessation of exercise. Acute exercise also led to longer total initiation times, which were linked to better response inhibition of planning at 30 and 60 min after the cessation of exercise.ConclusionAcute exercise benefits planning, and the types of planning and the time points at which they were assessed modulate the relationship between acute exercise and executive function. Exercise-induced physiological and biological fluctuations have been proposed to explain the effects present immediately after exercise, and the mechanisms of such effects warrant further exploration. 相似文献

The purpose was to examine differences in verbal interactions during the group counseling process and the relationship between perceived verbal interactions and members' demographic variables. 42 participants were recruited and randomly assigned to one of four counseling groups. Based on the Hill Interaction Matrix, Quadrant 4 verbal interactions, consisting of Speculative and Confrontative verbal behaviors in Personal and Relationship levels, were perceived significantly more often at the closing stage than at the initial stage. Furthermore, the perceived verbal interactions were related to the demographic variables of sex, educational level, and group experience, but not acquaintanceship. The findings suggested that the higher ratings of perceived Speculative and Confrontative verbal behaviors and the lower ratings of Assertive and Silence verbal interactions must be interpreted cautiously from a cross-cultural perspective, especially in Asian cultures. 相似文献

The association between self-deception and moral self-concept as functions of self-consciousness 总被引:1,自引:0,他引:1

Regulated by self-consciousness, self-deception is a part of the self-system that suppresses negative aspects of the self and maintains a positive moral self-concept. We tested this evolutionary hypothesis on 166 college students by measuring self-deception using both a questionnaire and a series of hypothetical helping scenarios. The results showed a positive correlation between self-deception and moral self-concept, which was moderated by private self-consciousness. Among participants with high, but not low, self-consciousness, high moral self-concept individuals were more willing to help when potential self-benefits were present than low moral self-concept individuals, whereas there was no difference between the two groups concerning helping without self-benefit. These results support the evolutionary view that self-deception serves to maintain optimal moral self-concept, especially for individuals with high self-consciousness. 相似文献

论德性的项目及其类型 总被引:2,自引:0,他引:2
在人类长期的道德实践中,德性常常是以德性项目的形式出现的。当德性进入伦理学的视野以后,伦理学家们基于对德性的本性及其项目的反思,提出一些德性项目并进一步对德性进行分类,将不同的德性项目纳入不同的类型。从伦理学的意义上看,德性的项目与德性的分类是紧密相联的。 相似文献

Despite the clear relationship of physical activity and quality of life (QoL), QoL measures are seldom targeted for physical
activity and health promotion. The current research attempted to address that gap by developing a QoL measure based on a conceptual
model that reflects positive health and is relevant for physical activity and health promotion programs. In the project, which
extended over three phases, an initial 70-item QoL survey was administered to university students and community program participants
(total n = 512) along with measures of satisfaction with life and physical activity. Exploratory and confirmatory factor analyses
revealed clear social, emotional, cognitive, physical, spiritual and functional (ADL) QoL factors as well as integrated QoL.
The resulting 32-item QoL Survey fits the conceptual model, demonstrates logical relationships with physical activity and
has sufficient psychometric properties for use in related research and health promotion programs. 相似文献
