Firms in global high technology industries face key challenges. This paper presents an integrative framework that delineates aspects of their context, organization and human resources. It also identifies tensions within the firm that can only be resolved by increasing the capacity of the firm to deal with multiple and conflicting pressures. High technology firms muct be adept at resolving tensions and learning in a very fast paced and changing world.  相似文献

Adolescents of Anglo-Celtic, Greek, Italian and Chinese descent attending a wide range of post-secondary institutions in Victoria (mean age = 18 years) were asked about their sexual behaviours, knowledge about AIDS, and social responses to the threat of AIDS. There was evidence of relatively high levels of sexual activity, with some members of all groups engaging in risky sexual behaviour. Anglo-Australians were more sexually active and informed about AIDS, with more equality between the sexes in these respects than the other groups. There was a distinction made between behaviours regarded as safe with regular and casual partners, but the meaning attributed to regular partnership differed. Greek- and Italian-Australian young men endorsed monogamy for their regular partners but not necessarily for themselves, and Anglo-Australians accepted a relationship of shorter duration as regular. Greater knowledge was not related to safer sexual behaviour, but discussion about a regular partner's previous sexual history correlated with more risky sexual behaviour. Overall, risk levels were not high but the casual-regular partner distinction, together with the greater use of relatively unrealistic strategies for dealing with AIDS in association with risky behaviour in the non-Anglo groups, gives cause for concern.  相似文献

This article retrieves part of our historical past to address two omissions in American feminist sociology on the subject of global imperialism. The first section addresses the inadequate attention feminist sociologists have paid to how major leaders of the women's movement responded to U.S. overseas expansion in the late nineteenth and early twentieth centuries. It documents how these early feminists had both progressive and reactionary responses to the anti‐imperialist struggles of their era. Particular emphasis is given to how issues of race, class, and gender were interwoven in their discourses on imperialism. The second section focuses on how the writings of the most famous woman theorist and critic of imperialism during this era—Rosa Luxemburg—are virtually ignored in U.S. portrayals of feminist sociology and women founders of sociology. To address this omission, Luxemburg's theory of imperialism is examined, as well as how it has influenced contemporary global feminist works. A critical analysis of these Luxemburg‐inspired works considers their implications for understanding global imperialism today. In this way, the past is used to clarify the present.  相似文献

Quantitative trait loci (QTL) mapping is a growing field in statistical genetics. In plants, QTL detection experiments often feature replicates or clones within a specific genetic line. In this work, a Bayesian hierarchical regression model is applied to simulated QTL data and to a dataset from the Arabidopsis thaliana plants for locating the QTL mapping associated with cotyledon opening. A conditional model search strategy based on Bayesian model averaging is utilized to reduce the computational burden.  相似文献

Across three experiments, we examined 9‐ and 11‐month‐olds' mappings of novel sound properties to novel animal categories. Infants were familiarized with novel animal–novel sound pairings (e.g., Animal A [red]–Sound 1) and then tested on: (1) their acquisition of the original pairing and (2) their generalization of the sound property to a new member of a familiarized category (e.g., Animal A [blue]–Sound 1). When familiarized with a single exemplar of a category, 11‐month‐olds showed no evidence of acquiring or generalizing the animal–sound pairings. In contrast, 11‐month‐olds learnt the original animal–sound mappings and generalized the sound property to a novel member of that category when familiarized with multiple exemplars of a category. Finally, when familiarized with multiple exemplars, 9‐month‐old infants learnt the original animal–sound pairing, but did not extend the novel sound property. The results of these experiments provide evidence for developmental differences in the facilitative role of multiple exemplars in promoting the learning and generalization of information.  相似文献

Using comparable self‐reported survey data collected among college students in the United States (n = 502) and Japan (n = 441), this study examines a paradox of higher academic deviance among otherwise more conforming Japanese youth while revisiting the debate concerning the disjuncture between aspirations and expectations/perceived outcomes in Agnew's general strain theory (GST). Confirming the paradox, our results indicate that Japanese students are significantly more deviant academically than American students. However, contrary to the expectation of GST, but in support of past empirical studies, the higher academic deviance among the Japanese, as compared to Americans, is explained by their lower aspirations, irrespective of the levels of expectations/perceived outcomes  相似文献

Components of nursing home (NH) culture change include resident-centeredness, empowerment, and home likeness, but practices reflective of these components may be found in both traditional and “culture change” NHs. We use mixed methods to examine the presence of culture change practices in the context of an NH’s payer sources. Qualitative data show how higher pay from Medicare versus Medicaid influences implementation of select culture change practices, and quantitative data show NHs with higher proportions of Medicare residents have significantly higher (measured) environmental culture change implementation. Findings indicate that heightened coordination of Medicare and Medicaid could influence NH implementation of reform practices.  相似文献

BackgroundTo compare the knowledge and preference of preconceptional contraception to future postpartum contraceptive method choice in high-risk pregnancies.Research questionDoes a high-risk pregnancy condition affect future postpartum contraceptive method choice?MethodWomen hospitalised at the High Risk Pregnancy unit of a tertiary research and training hospital were asked to complete a self-reported questionnaire that included demographic characteristics, presence of unintended pregnancy, contraceptive method of choice before the current pregnancy, plans for contraceptive use following delivery and requests for any contraceptive counselling in the postpartum period.FindingsA total of 655 pregnant women were recruited. The mean age, gravidity and parity of the women were 27.48 ± 6.25 years, 2.81 ± 2.15 and 1.40 ± 1.77, respectively. High-risk pregnancy indications included 207 (31.6%) maternal, 396 (60.5%) foetal and 52 (7.9%) uterine factors. All postpartum contraceptive choices except for combined oral contraceptives (COCs) usage were significantly different from preconceptional contraceptive preferences (p < 0.001). High-risk pregnancy indications, future child bearing, ideal number of children, income and education levels were the most important factors influencing postpartum contraceptive choices. While the leading contraceptive method in the postpartum period was long-acting reversible contraceptive methods (non-hormonal copper intrauterine device Cu-IUD, the levonorgestrel-releasing intrauterine system (LNG-IUS) (40%), the least preferred method was COCs use (5.2%) and preference of COCs use showed no difference between the preconceptional and postpartum periods (p = 0.202). Overall 73.7% of the women wanted to receive contraceptive counselling before their discharge.ConclusionA high-risk pregnancy condition may change the opinion and preference of contraceptive use, and also seems to affect the awareness of family planning methods.  相似文献

BackgroundAccording to the psychoanalytical literature, it is during pregnancy that maternal representations of the mother–infant relationship become activated. Midwives who are engaged with the mother and the baby have not drawn upon this concept in their practice. In order for this to happen, it is important to understand better the nature of maternal representations and when they are activated from empirical studies.QuestionThe research question is: what are the maternal representations of a group of first time mothers from pre-pregnancy, early pregnancy and to the first ultrasound.MethodA narrative approach was used to gain insight into the maternal representations of first time pregnant womens’ account of their representations. The analysis method was based on thematic approach.ParticipantsFifteen women aged between 23 and 38 years.SettingA midwives clinic attached to a tertiary hospital in Melbourne, Australia.FindingsFirst-time pregnant women's maternal representations were activated when a woman begins to plan her pregnancy (‘the time is right’), again at the onset of physical changes to her body as a result of conception (‘my body is changing’), and at the first early ultrasound at around twelve weeks (‘it’ is a real baby).ConclusionMaternal representations are important for the midwife and pregnant women because this concept provides another understanding in relation to the psychological dimension of pregnancy.  相似文献
