新日铁住金不锈钢公司(NSSC)开始研究针对日本国内销售不锈钢板的“仓库交货”的最佳方法。过去该公司对与其直接进行交易的一级批发商全部是将不锈钢薄板(钢卷)及中厚板送到订货方指定的钢卷加工中心或者剪切工厂交货。但是考虑到配送费用负担大、实际费用发生的成本应由订货方负担一部分,作为新销售制度的一个环节,该公司开始研究适合本公司“仓库交货”的最佳方法。  相似文献

广东西南冷轧厂有一台B700型冷轧带钢分条机组,是用于生产2×700mm以下冷轧带钢的分条机组。该机组投产后,主要问题是:钢卷在卷取机上卷不紧,或卷取机与圆盘剪机不同步的情况。因而难以保证该机组的正常生产,经常造成故障停车。经分析得知:主要是卷取机与圆盘剪机线速度不一致造成。因为该卷取机为无心卷取,随着钢卷越来越大,钢卷在卷取机上打滑也越来越厉害,这样就造成了该卷取机的一些主要问题。改造的目标是减少分条机组故障停车,提高分条机组的生产能力,降低机组的维护费用。改造措施主要是采用电磁调速电机代替分…  相似文献

While research on spinal cord injury (SCI) is abundant, few studies focus on women. This population-based study investigates differences in the prevalence of secondary conditions between 128 women and 522 men. Case managers retrospectively interviewed 650 persons regarding medical and psychological conditions secondary to SCI, as well as other life issues. Overall, males and females show more similarities than differences in the ways in which they manage life with SCI. Differences were found, though, regarding etiology of initial injury, insurance coverage, caregiver use, transportation use, medication use, and in other medical and behavioral areas. Females are significantly involved in more automobile crashes than males, while males are involved in more galls than females. Females are more reliant on Medicaid, while males report more Medicare and Worker's Compensation coverage. Females are more likely to have a paid attendant as a caregiver while males are more likely to have their spouse or parents assist. Males report more independence in their use of transportation than females. Males and females also report significant differences in the use of medication. Females are more likely to use medication any time it is a treatment option. Males are more active, use tobacco more and have more arm fractures postinjury than females.  相似文献

Why do some individuals choose to drink alcohol, smoke cigarettes, and use illegal drugs while others do not? The origin of individual preferences and values is one of the remaining theoretical questions in social and behavioral sciences. The Savanna-IQ Interaction Hypothesis suggests that more intelligent individuals may be more likely to acquire and espouse evolutionarily novel values than less intelligent individuals. Consumption of alcohol, tobacco, and drugs is evolutionarily novel, so the Savanna-IQ Interaction Hypothesis would predict that more intelligent individuals are more likely to consume these substances. Analyses of two large, nationally representative, and prospectively longitudinal data from the United Kingdom and the United States partly support the prediction. More intelligent children, both in the United Kingdom and the United States, are more likely to grow up to consume more alcohol. More intelligent American children are more likely to grow up to consume more tobacco, while more intelligent British children are more likely to grow up to consume more illegal drugs.

Seven studies provide evidence that representations of the self at a distant-future time point are more abstract and structured than are representations of the self at a near-future time point and that distant-future behaviors are more strongly related to general self-conceptions. Distant-future self-representations incorporate broader, more superordinate identities than do near-future self-representations (Study 1) and are characterized by less complexity (Study 2), more cross-situational consistency (Study 3), and a greater degree of schematicity (Study 4). Furthermore, people's behavioral predictions of their distant-future (vs. near-future) behavior are more strongly related to their general self-characteristics (Study 5), distant-future behaviors are seen as more self-expressive (Study 6), and distant-future behaviors that do not match up with acknowledged self-characteristics are more strongly rejected as reflections of the self (Study 7). Implications for understanding both the nature of the self-concept and the way in which distance may influence a range of self-processes are discussed.

Poor children confront widespread environmental inequities. Compared with their economically advantaged counterparts, they are exposed to more family turmoil, violence, separation from their families, instability, and chaotic households. Poor children experience less social support, and their parents are less responsive and more authoritarian. Low-income children are read to relatively infrequently, watch more TV, and have less access to books and computers. Low-income parents are less involved in their children's school activities. The air and water poor children consume are more polluted. Their homes are more crowded, noisier, and of lower quality. Low-income neighborhoods are more dangerous, offer poorer municipal services, and suffer greater physical deterioration. Predominantly low-income schools and day care are inferior. The accumulation of multiple environmental risks rather than singular risk exposure may be an especially pathogenic aspect of childhood poverty.

Parents who repartner after divorce must decide how to balance the potentially competing demands of their own desire for adult companionship and romance with the needs of their children for parental attention and affection. In this study, the authors assessed individual differences in divorced custodial mothers' orientation toward repartnering, characterizing it as a continuum, ranging from more child focused to more adult focused. Mothers who are more adult focused tend to be older, more educated, more likely to be employed outside the home, and exiting marriages of longer duration. In addition, using longitudinal data from in-home interviews, mothers who are more adult focused reported having lower rapport with their children, spending less time in joint activities with their children, and their children in turn reported lower rapport with their mothers. Levels of adult-focused orientation are relatively stable over time but increase when mothers become involved or interested in new partners. Using longitudinal diary data over a 2-year period, the authors demonstrated that mothers who are more child focused engage in more active management of emergent relationships in repartnered families and that adult-focused and child-focused mothers respond to different concerns. Whereas all mothers become more active in managing emergent relationships when both partner and child are resisting one another, mothers with greater child focus respond more to concerns of the child, and mothers with greater adult focus respond more to the concerns of the partner. Implications for intervention with divorced families are discussed. (PsycINFO Database Record (c) 2011 APA, all rights reserved)  相似文献

Across 2 experiments, the authors demonstrate that emotional states influence how receptive people are to advice. The focus of these experiments is on incidental emotions, emotions triggered by a prior experience that is irrelevant to the current situation. The authors demonstrate that people who feel incidental gratitude are more trusting and more receptive to advice than are people in a neutral emotional state, and people in a neutral state are more trusting and more receptive to advice than are people who feel incidental anger. In these experiments, greater receptivity to advice increased judgment accuracy. People who felt incidental gratitude were more accurate than were people in a neutral state, and people in a neutral state were more accurate than were people who felt incidental anger. The results offer insight into how people use advice, and the authors identify conditions under which leaders, policy makers, and advisors may be particularly influential.

Ano-genital neoplasia is about 20 x more common in renal transplant patients than the general population. Neoplasms in the immunosuppressed are more morbid and mortal because: patients are younger; tumors are more undifferentiated; they have more and larger foci; more sites are involved; neoplasms tend to persist, recur and progress; and there are more complications from treatments. Intraepithelial neoplasia engenders some morbidity. Invasion is rarer, but when it occurs, it is always morbid, and all too often mortal. Invasive ano-genital cancer is primarily preventable because the lower genital and anal tracts are accessible to inspection, cytologic screening, endoscopy and biopsy. Prime prevention is avoiding infection with the Human Papilloma Virus (HPV). Next best is detecting HPV/intraepithelial neoplasia early with frequent inspection, cytology and liberal biopsies; and then removing any condylomas or intraepithelial neoplasia that develop.  相似文献

The Physical and Architectural Features Checklist (PaF) measures the physical resources of sheltered care settings in terms of nine conceptually unified and empirically derived dimensions. The development of the PAF is described, and psychometric characteristics, based on data from 93 representative facilities, are presented. These data show that facilities which have more physical resources are seen as attractive by outside observers and pleasant by residents. Larger facilities are more likely to provide barrier-free environments, more flexible physical settings, and more staff facilities. Cost is not related to any PAF dimension; however, nonprofit facilities score higher on several dimensions than do proprietary facilities. Richer physical settings tend to offer residents more policy resources. They are more selective, provide more privacy, allow residents a higher degree of influence and choice, and have clearer policies. Sample profiles illustrate the usefulness of this instrument for describing and comparing facilities; additional uses are discussed.  相似文献

To understand the consequences of adolescent pregnancy and childbearing on siblings, a study compares 309 younger brothers and sisters of pregnant, parenting and never-pregnant teenagers. Compared with the younger siblings of never-pregnant teenagers, the younger sisters of pregnant teenagers see school and career as less important, are more accepting of adolescent childbearing, perceive younger ages as appropriate for first intercourse, marriage and childbearing and engage in more problem behavior. The younger sisters of parenting teenagers are more accepting of teenage childbearing than are younger sisters of never-pregnant teenagers and have more definite intentions of having a child at a young age. Compared with boys who have a never-pregnant older sister, younger brothers of pregnant and parenting teenagers are more accepting of nonmarital childbearing, ascribe more importance to childbearing, perceive fewer problems related to early childbearing, have lower self-esteem and report engaging in more drug use and partying behavior.  相似文献
