Lerne die Regeln um sie zu verändern! Die Rolle der Organisationslogik in Veränderungsprozessen

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.     

Young Adult Migration from a Northern Plains Indian Reservation: Who Stays and Who Leaves

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.

Cumulative Risk for Early Sexual Initiation Among American Indian Youth: A Discrete‐Time Survival Analysis

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.     

The Association of Couples’ Relationship Status and Quality With Breastfeeding Initiation

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.     

Understanding Vulnerability: From Categories to Experiences of Young Congolese People in Uganda

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.

A Collaborative Approach to Infant Research: Promoting Reproducibility,Best Practices,and Theory‐Building

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.     

Max-stable processes for modeling extremes observed in space and time

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.
