This article conceptualizes and empirically examines buyer–supplier relationships in respect of supply sourcing strategies, relationship characteristics and firm performance. Two sourcing strategies available to organizations are examined, critical and leverage, which in turn, influence the approach to managing the supplier relationship (arms‐length or collaborative). We argue that different relationship approaches are appropriate to achieving different performance outcomes. A structural equation model, using a sample of 142 manufacturing firms based in the United Kingdom, is used to test this hypothesized model. The results indicate that a critical sourcing strategy requires collaborative supplier relationships in order to achieve higher relationship and business outcomes, while leverage sourcing strategies have a direct impact on these same performance outcomes. In addition, a leverage strategy was associated with increased levels of supplier power, though this power was found not to have a significant effect on performance. Our study provides support for the importance of aligning sourcing strategies to particular supplier relationship approaches in order to improve firm performance. Managerial implications of these findings and future directions for research are then offered. 相似文献

The cognitive and behavioral status at age six years of 185 children of adolescent mothers (60.5% boys) were assessed using the mother (CBCL) and teacher (TRF) report forms of the Child Behavior Checklist and the Bracken Basic Concepts Scale. There was evidence for impairment in all areas of functioning. More than half of the sample exceeded the borderline clinical cutoff (T = 60) on either the CBCL or TRF Total Problem score, and nearly half the sample had Bracken scores that were more than 1 SD below the normative mean. Only 26.9% of the children were in the normal range on all three measures. These results are discussed in terms of implications for social work practice with children and adolescent mother families. 相似文献

Tamotsu Shibutani is a contemporary proponent of the Chicago School of pragmatic sociology who has devoted his academic efforts to using the Chicago School of pragmatism to analyze problems of contemporary social life and to refine the theoretical tools available to the discipline of sociology. He has evaluated such topics as the Japanese relocation centers, the social construction of rumor, demoralization in Army life, the dynamics of ethnic stratification, and the resolution of ethnic tensions. Shibutani's books on social psychology and general sociology synthesize micro and macro variables, with careful attention to both agency and social control. His work is free of metaphysical puzzles and is true to the scientific method, clearly reflecting the essence of the Chicago School of pragmatic sociology. 相似文献

This article examines the effect of socialization mechanisms and supplier performance measurement on the level of supplier integration in new product development and subsequent firm performance outcomes. Prior research has found socialization mechanisms and performance measures to be effective in managing supplier relationships, though research examining their impact within a product development context has been limited. Socialization mechanisms, such as supplier conferences and on‐site visits, help establish communication and information‐sharing routines necessary to achieve supplier integration in the product development process. Using performance measures to evaluate a supplier helps focus managerial attention on areas such as innovation and communication that are important to integration success. A structural equation model, using a sample of 142 manufacturing firms based in the United Kingdom, indicates that the level of supplier integration in new product development is positively influenced by socialization mechanisms and innovation‐focused measures of supplier performance, but not significantly associated with the use of communication measures. In turn, increased levels of supplier integration led to improvements in both collaboration outcomes and business performance. Socialization mechanisms were also found to have a direct effect on collaboration outcomes achieved by the firm. Managerial implications and future research directions are discussed. 相似文献

Long-term marriages of 21 retired working class couples were examined for the post-retirement effects on the marriage's social integration, happiness, involvement and satisfaction. Evidence suggests that marital patterns evolving in response to the work situation result in different types of relationships for dual paycheck and traditional couples. While both groups were happy, satisfied and involved in home, family and their own dyadic relationship, dual paycheck couples had more egalitarian and cooperative relationships. Their increased happiness, satisfaction and involvement are indicative of the benefits of their former dual employment. 相似文献

We examine methods for reducing respondent burden in evaluating alter–alter ties on a set of network structural measures. The data consist of two sets, each containing 45 alters from respondent free lists: the first contains 447 personal networks, and the second 554. Respondents evaluated the communication between 990 alter pairs. The methods were (1) dropping alters from the end of the free-list, (2) randomly dropping alters, (3) randomly dropping links, and (4) predicting ties based on transitivity. For some measures network structure is captured with samples of less than 20 alters; other measures are less consistent. Researchers should be aware of the need to sample a minimum number of alters to capture structural variation. 相似文献

This case study describes therapy over a three year period with a young adopted person who presented as highly suicidal, with a childhood background characterised by severe privation and abuse. The paper describes the use of a visual Life line, designed to assist the young person in reconnecting and honouring different parts of her life. A flexible and client centred therapeutic approach is also described. 相似文献

The life orientation test-revised (LOT-R) (Scheier et al. in Journal of Personality and Social Psychology 67:1063–1078, 1994) is a brief measure for assessing dispositional optimism. The aim of this study was to develop a Greek language version of
the LOT-R and to assess the instrument’s psychometric properties. The LOT-R was translated and culturally adopted in Greek
language, and the final version was administered, along with a questionnaire consisting socioeconomic characteristics and
a single item measuring optimism, to 276 Greek speaking, hospital nurses (222 female, 54 male), aged 22–65 years (mean 37.8,
SD 8.3). Results showed that the LOT-R has good internal consistency (Cronbach’s α = .71 and item total correlation coefficients from .27 to .73, a unitary structure, and stability over a 3-months period
(r = .66). Moreover, the Greek version of the scale exhibited good convergent validity with single-item optimism scale (r = .73). Principal components analysis revealed a two-factor structure representing the constructs of optimism and pessimism.
The Greek life orientation test revised appears to be a valid tool in assessing dispositional optimism in Greek speaking people
and is expected to facilitate the examination of optimism in Greek speaking populations. 相似文献

Contrary to Bourdieu’s theory (Distinction: A social critique of the judgment of taste. Cambridge, Massachusetts: Harvard
University Press (1984)) that cultural consumption of so-called “high” versus popular culture is determined by socio-economic
class, Peterson (Poetics 21:243–258, 1992; Poetics 33:257–282, 2005) finds that higher income and education groups are more
likely to be “cultural omnivores”—consumers of a wide variety of both high and popular cultural goods. Omnivores were also
found to be much less likely to exclude other cultures and to be more open to, and tolerant of, the views of others than those
with narrower cultural tastes, called “cultural univores”. This article investigates the omnivore/univore hypothesis in a
South African context, using survey data collected from 500 attendees of live theatre performances at the National Arts Festival
in 2008. Multiple correspondence analysis (also called perceptual mapping) shows an interesting intermediate state between
Boudieu-like high culture univores and Peterson omnivores, which could have interesting implications for the development of
social tolerance in multi-cultural South Africa. 相似文献
