Global supply chain design: A literature review and critique 总被引:7,自引:1,他引:7

In this paper, we review decision support models for the design of global supply chains, and assess the fit between the research literature in this area and the practical issues of global supply chain design. The classification scheme for this review is based on ongoing and emerging issues in global supply chain management and includes review dimensions for (1) decisions addressed in the model, (2) performance metrics, (3) the degree to which the model supports integrated decision processes, and (4) globalization considerations. We conclude that although most models resolve a difficult feature associated with globalization, few models address the practical global supply chain design problem in its entirety. We close the paper with recommendations for future research in global supply chain modeling that is both forward-looking and practically oriented. 相似文献

In Flak/Schmid (1993) an outlier test for linear processes was introduced. The test statistic bases on a comparison of each
observation with a one-step predictor. It was assumed that an upper bound for the total number of outlierss
n is known, wheren denotes the sample size. The asymptotic distribution of the test statistic was derived under the assumption thats
n/n → 0 ands
n → ∞ asn → ∞. This note deals with the asymptotic behaviour of this quantity, ifs
n/n →p
0 ∈ (0, 1). 相似文献

This study considered the utility of gender schema theory in examining girls' website design preferences. It built on a previous
study which identified eight website evaluation criteria related to biological sex: collaboration, social connectivity, flexibility,
motility, contextuality, personal identification, inclusion, and graphic/multimedia concentration. Eleven fourteen-, fifteen-,
and sixteen-year-old girls participated in the study. The participants completed the short form of the Children's Sex-Role
Inventory (CSRI). Following 50-minute Web searching sessions, they were divided into a feminine-high group and a masculine-high
group based on their CSRI scores. Each group then participated in interviews concerning their website evaluation and design
preferences. Data analysis identified relationships between gender schema and five of the proposed criteria: social connectivity,
flexibility, motility, inclusion, and graphic/multimedia concentration. More generally, members of the feminine-high group
favored evaluation criteria relating to graphic and multimedia design, whereas members of the masculine-high group favored
evaluation criteria relating to subject content. These results indicate that gender schema theory can indeed serve as a framework
for making website design more appealing to female adolescent users.

Financial data are typically not identically, independently and normally distributed (iid-normal). Yet, standard tests of asset-pricing models are based on this assumption, and we have little information on how sensitive the tests are to violations of iid-normality. Recent evidence suggests that test outcomes may be sensitive to these violations. In this paper, we use Australian data to compare the standard test results with those that do not require iid-normality: the GMM-J test and bootstrap-based tests. We find that different tests produce differences in prob values at least as large as those in US studies but that test outcomes are generally robust. 相似文献

20世纪90年代中期以来,我国反贫困的步伐明显放缓。这是因为在反贫困的运行过程中,无论是对贫困内涵的理论把握,贫困人员的结构改变,还是对因公共供给不足而返贫的现实认识以及反贫困的制度设计都存在着缺陷和误区。因此,要治理贫困恶性循环,就必须从多维角度出发,选择新的符合新发展观和和谐社会要求的综合反贫困路径。 相似文献

This paper examines the effect of attending a Catholic high school on educational outcomes. The statistical analysis is based on data obtained from the US National Educational Longitudinal Study. Using propensity score matching methods to control for selection bias, we find that Catholic schooling improves maths test scores, with stronger effects for males than for females, but appears to have little effect (if any) on reading scores. Catholic schooling also raises high school graduation rates and substantially increases the likelihood of enrolment in a 4‐year college. Use of the difference‐in‐difference method suggests that the effect of Catholic schooling on changes in maths scores is more muted, though still statistically significant. 相似文献
