In this article we introduce the concept of the firm’s organizational logic and how it influences organizational change processes. Characteristics and the essence of the organizational logic are explained and then illustrated by mean of a real-world case. Depending on the level of organizational change – whether it leads to single-loop, double-loop or deutero learning – we provide different implications for change agents to make use of the organizational logic to steer organizational change successfully. 相似文献

We evaluated how ambitions, community ties, monetary sufficiency, employment, and alcohol consumption related to whether young
American Indian adults had moved from their Northern Plains reservation. Of 518 Northern Plains reservation residents in 1993,
we located 472 in 2003–2005 and found that 89 lived more than a four-hour drive from the reservation. Coding the 472 as to
whether they had stayed on/near the reservation or moved away, we ran logistic regressions on data they reported in 1996 to
determine which demographic and attitudinal variables were associated with having moved. We found ambitions and goals were
more associated with moving away than were ties to the community, which in turn were more related than monetary and personal
characteristics that promote independence and prosperity. The more importance they placed on getting a good education or carrying
on the tribe’s traditions, the more likely they were to have moved away. We found too that the odds of moving away decreased
with greater alcohol consumption. Tribal council members and college administrators therefore may wish to promote policies
that increase opportunities for young adults to achieve higher education goals while remaining on reservation to carry on
tribal traditions. Benefits may also come from encouraging and assisting reservation members studying off-reservation to return
after completing their education. These findings would argue too for greater investment in alcohol services for reservation-dwelling
populations. 相似文献

儿童福利机构中的类家庭养育 总被引:1,自引:0,他引:1
创设类家庭养育模式
类家庭养育与传统机构养育的不同
类家庭养育模式在很多方面的优势对幼童的健康成长是至关重要的。从结构角度来看,家庭由相对较小的团体构成,尤其是相对少的儿童。如果孩子不止一个,那么不同年龄、性别、或者有特殊需要的儿童都住在一起。 相似文献

Approximately 3 million teens are diagnosed with a sexually transmitted disease (STD) annually; STDs rates for American Indian young adults are among the highest of any racial/ethnic group. An important risk factor for STDs is early initiation of sex. In this study, we examined risk for early initiation with 474 American Indian youth ages 14–18, using 11 risk factors from three developmentally important microsystems (family, school, peers) along with several individual characteristics; a cumulative risk index was also calculated. Discrete‐time survival analyses showed that predictors of early initiation differed by gender. For young men, younger initiation of sex was predicted by lower grades, liking school less, having peers with less prosocial attitudes, a greater likelihood of having used alcohol or drugs at first sex, and having higher sensation‐seeking. For young women, earlier initiation was related to having mothers who had their first child at an early age and who had less formal education, to having parents who had divorced, dropping out of high school, using alcohol/drugs at first sex, and higher sensation‐seeking. Higher cumulative risk was associated with elevated risk of sexual initiation, although the degree of added risk varied with age for women. Cumulative risk deserves broader attention in understanding the early initiation of sexual intercourse. 相似文献

Using data from the Fragile Families and Child Wellbeing Survey (N= 3,567), we examine the links between relationship status, relationship quality, and race and ethnicity in breastfeeding initiation. We consider four relationship types: married, cohabiting, romantically involved but not cohabiting (termed visiting), and nonromantically involved mothers. We find that even after adjusting for a wide range of sociodemographic factors, married mothers were more likely to breastfeed than unmarried mothers and that racial and ethnic differences in breastfeeding do not result from differences in marriage rates. Among unwed mothers, paternal provision of money or other assistance during pregnancy decreases the likelihood of breastfeeding. We conclude that relationship status, above and beyond demographic characteristics, is an important correlate of breastfeeding. 相似文献

This article problematises the ‘vulnerables’ category that the United Nations High Commissioner for Refugees applies to groups of refugees. Drawing on 9 months’ qualitative research with young Congolese refugees in Uganda, it presents research subjects’ self‐identification and lived realities that do not correspond to the homogenous, fixed ‘vulnerables’ ideal. Moreover, it argues that the ‘vulnerables’ categorisation approach can provoke a number of counter‐productive effects, including a focus on symptoms rather than causes, inflated numbers of ‘vulnerables’ and undermining indigenous support structures. An alternative approach that interrogates and addresses the contextual and relational aspects of vulnerability is proposed. 相似文献

A Collaborative Approach to Infant Research: Promoting Reproducibility,Best Practices,and Theory‐Building 下载免费PDF全文

The ideal of scientific progress is that we accumulate measurements and integrate these into theory, but recent discussion of replicability issues has cast doubt on whether psychological research conforms to this model. Developmental research—especially with infant participants—also has discipline‐specific replicability challenges, including small samples and limited measurement methods. Inspired by collaborative replication efforts in cognitive and social psychology, we describe a proposal for assessing and promoting replicability in infancy research: large‐scale, multi‐laboratory replication efforts aiming for a more precise understanding of key developmental phenomena. The ManyBabies project, our instantiation of this proposal, will not only help us estimate how robust and replicable these phenomena are, but also gain new theoretical insights into how they vary across ages, linguistic communities, and measurement methods. This project has the potential for a variety of positive outcomes, including less‐biased estimates of theoretically important effects, estimates of variability that can be used for later study planning, and a series of best‐practices blueprints for future infancy research. 相似文献

Max-stable processes have proved to be useful for the statistical modeling of spatial extremes. For statistical inference it is often assumed that there is no temporal dependence; i.e., that the observations at spatial locations are independent in time. In a first approach we construct max-stable space–time processes as limits of rescaled pointwise maxima of independent Gaussian processes, where the space–time covariance functions satisfy weak regularity conditions. This leads to so-called Brown–Resnick processes. In a second approach, we extend Smith’s storm profile model to a space–time setting. We provide explicit expressions for the bivariate distribution functions, which are equal under appropriate choice of the parameters. We also show how the space–time covariance function of the underlying Gaussian process can be interpreted in terms of the tail dependence function in the limiting max-stable space–time process. 相似文献
