Environmental practices have not received as much research attention in emerging market contexts as traditional topics like quality. However, the importance of environmental practices for a firm’s production strategy has been increasing at an unprecedented level across the globe. Our research objective is, therefore, to investigate the interplay between environmental practices and quality in the pursuit of firm performance. Relying on 492 responses from Turkish manufacturers to test our hypotheses, we show that environmental practices directly improve the quality of products over and above the effect of quality management practices in emerging markets. Product quality, in turn, is important for increasing firm performance, acting as a mediator for the positive effects of environmental practices on performance. Thus, we reveal that product quality functions as an instrumental conduit between environmental practices and firm performance in emerging markets like Turkey where stakeholder pressures are weak, and regulations are often not properly enforced. 相似文献

Psychometric growth curve modeling techniques are used to describe a person’s latent ability and how that ability changes over time based on a specific measurement instrument. However, the same instrument cannot always be used over a period of time to measure that latent ability. This is often the case when measuring traits longitudinally in children. Reasons may be that over time some measurement tools that were difficult for young children become too easy as they age resulting in floor effects or ceiling effects or both. We propose a Bayesian hierarchical model for such a scenario. Within the Bayesian model we combine information from multiple instruments used at different age ranges and having different scoring schemes to examine growth in latent ability over time. The model includes between-subject variance and within-subject variance and does not require linking item specific difficulty between the measurement tools. The model’s utility is demonstrated on a study of language ability in children from ages one to ten who are hard of hearing where measurement tool specific growth and subject-specific growth are shown in addition to a group level latent growth curve comparing the hard of hearing children to children with normal hearing.KEYWORDS: Bayesian hierarchical models, psychometric modeling, language ability, growth curve modeling, longitudinal analysis 相似文献

The application of optimization techniques in digital simulation experiments is frequently complicated by the presence of large experimental error variances. Two of the more widely accepted design strategies for the resolution of this problem include the assignment of common pseudorandom number streams and the assignment of antithetic pseudorandom number streams to the experimental points. When considered separately, however, each of these variance-reduction procedures has rather restrictive limitations. This paper examines the simultaneous use of these two techniques as a variance-reduction strategy in response surface methodology (RSM) analysis of simulation models. A simulation of an inventory system is used to illustrate the application and benefits of this assignment procedure, as well as the basic components of an RSM analysis. 相似文献

In this study, I examine disparities in schooling progress among children born to immigrant and U.S.-born blacks. I find that
in one- and two-parent families, children born to black immigrants are less likely to fall behind in school than those born
to U.S.-born blacks. In two-parent immigrant families, children born to two immigrant parents have a significant schooling
advantage over children born to one immigrant parent. While children born to two immigrant parents in the wealthiest black
immigrant families do better in the second generation than in the first, the reverse is observed among children in less wealthy
families. These findings contribute in two ways to our understanding of the assimilation processes of children born to black
immigrant parents. First, they show that there is a positive association between the number of immigrant parents in a family
and children’s schooling performance. Second, they suggest that disparities in the assimilation patterns of the children of
black immigrants are a likely product of the interaction between their parental characteristics and the socioeconomic circumstances
of their families. 相似文献

In this paper three prominent discourses of Entrepreneurship Research — 1) the Entrepreneur as an actor in society, 2) the embeddedness of the research object of Entrepreneurship Research and 3) the determinants of entrepreneurship processes — are analyzed for possible interfaces between a sociological and economical perspective. This analyses results in a systemized portfolio of research topics, which seem to be especially attractive for such an integrative research approach. The results of a survey of 105 entrepreneurship researchers in the German speaking world underpin the relevance of the identified interfaces and allow for their priorization. That way we contribute to an integration of this field as the presented set of identified interfaces, in a first step, provides a feasible agenda for interdisciplinary (empirical) follow-up research whose results — in a second step — can build elements of an integrative concept of Entrepreneurship Research. 相似文献

Based on a cohort of young Austrians of Turkish descent, this paper links the debate on the integration of the second generation (or the lack thereof) with the controversial discourse about the potential usefulness and risks of new media and technologies, specifically the Internet. Various studies have concluded either that the new media and technologies are positive integrative aspects of the society or have devastating impacts on different groups. On the one hand, the Internet allows young people to discover new experiences and gain additional often unorthodox knowledge; on the other hand, observers have warned about the segregating effects of new technologies. A ?digital divide“ has been opened between privileged users and the underprivileged masses, according to these more cautious voices. This divide has caused social deprivation and disintegration amongst the most vulnerable groups, in particular, older people, economically insecure groups and immigrants. Thus, various media life-styles establish a continuum between a media and information elite on the one end and the entertainment under-class on the other. Semi structured interviews with young Turks in Vienna show the positive and negative effects of playing Online Role Playing Games on the Internet in opposition to so-called Social Network Sites such as Netlog. 相似文献

The aim of the present article is to study how women's alcohol consumption has been defined and contested in the Swedish press from 1955 to 2010 in relation to the development of Swedish society from a social democratic welfare state to a neoliberal competition state. Our material consists of articles published in the largest Swedish national and regional newspapers in 1955, 1965, 1977, 1982, 1995, 2004, and 2010. In the study, we apply Fraser's concepts of recognition and redistribution to analyse how the press contributed to the formation of cultural injustices and counter-claims through its recognition of women's drinking, and how these cultural injustices and counter-claims have conditioned the redistribution of societal resources. Our analysis shows that, during the study period, women were recognized in the Swedish press in limited and stigmatizing subject positions. These dominating representations of drinking women changed over time in an unpredictable way. As collectively shared, widely accepted cultural images, they tended to downplay the possibility of women achieving equal and just participation in cultural interaction, social activities, and healthcare services. In counter-discourses, the possibilities for women to formulate public claims in order to make surrounding structures more “enabling” of their independency, weakened during the study period. 相似文献

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing
and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood.
We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories
during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood
that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen
motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood.
This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers
of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further
and thus reduce the need for welfare support and child support enforcement in the long run.
