In the fast moving software industry, projects have been increasingly developed by distributed teams, which are located in geographically remote offices and collaborate using information communication technologies. In such environments, project distribution presents specific challenges, as work in distributed teams increases project technical complexity, communication lines multiply and stakeholders’ interests may be divergent. Despite the importance and complexity of this type of problem, it seems that there is a lack of reports, in the literature, of systems that could support these decisions. This paper presents a real-world case study, where we developed a multi-criteria model for supporting the distributed team work allocation decision for a major global software company. It was developed with a group of software development project managers, using decision conferencing and multi-attribute value analysis. The model deals not only with software engineering attributes, but also “soft” and strategic issues, like team satisfaction and training opportunities. We also discuss some issues and challenges faced during this modelling process. 相似文献

“批对批”策略下关于供应商管理库存机制的一个探讨 总被引:1,自引:0,他引:1
本文考虑了一个由单供应商和单采购商构成的两级供应链系统,在供应商采取"批对批"策略下,引入VMI后将对供应链系统以及各渠道成员利益带来的影响.我们发现,渠道权力配置对VMI作为供应链企业间合作机制的有效性存在重要影响.在采购商占主导地位的渠道中,当系统参数满足一定条件时,引入VMI后可以同时降低供应商和采购商总成本,从而VMI可以成为供应商和采购商之间的有效合作机制.但在供应商占主导地位的渠道中,引入VMI必将增加供应商的总成本,此时VMI不是供应商和采购商之间的有效合作机制. 相似文献

湖南省地方高校原有的财政拨款模式,一般采用多目标财政拨款模式、基数加增长模式和调控性专项拨款模式等。这些拨款模式存在一定的缺陷,因此,采用多重目标合理组合的拨款思路,坚持公平、透明、有效的拨款原则,推行多政策参数的拨款公式,是改革湖南省地方高校拨款模式的策略选择。 相似文献

Studies of multiethnic families often assume the ethnic identification of children with the minority group results from the minority parent. This study examines an alternate view that mainstream parents also play an important role in transmitting minority ethnicity. It explores this argument using data from New Zealand on the ethnic labels mothers assign to their Maori‐European children. It finds that European mothers are just as disposed as Maori mothers to designate their child as Maori, either exclusively or in combination. Two explanations, grounded in ethnic awareness and gendered inheritance, are proposed. Although neither satisfactorily predicts maternal designation decisions, the readiness of European mothers to identify their child as Maori underscores their role in diffusing Maori ethnicity. 相似文献

This study examines child, parent, and situational correlates of familial ethnic/race socialization using nationally representative data gathered as part of the Early Childhood Longitudinal Study, Kindergarten Class of 1998 – 1999 (ECLS‐K). The ECLS‐K sample (N = 18,950) includes White, Black, Hispanic, Asian, Native Hawaiian/Pacific Islander, American Indian, and multiracial kindergarteners, with survey data available at the child, parent/guardian, teacher, and school level. We find that child correlates such as race and gender, parent correlates such as education and warmth of parent‐child relationship, and situational correlates such as percent of minorities at the child’s school and cultural event participation influence how often family members discuss children’s ethnic/racial heritage with them. We advocate for continued research of contextualized family dynamics. 相似文献

This article compares the extended family integration of Euro and Mexican American women and men and assesses the importance of class and culture in explaining ethnic differences. Using National Survey of Families and Households II data (N = 7,929), we find that ethnic differences depend on the dimension of integration. Mexican Americans exhibit higher rates of kin coresidence and proximity, but lower rates of financial support than Euro Americans. Two additional differences exist only among women: Mexican American women are more likely than Euro American women to give household or child care help. As to the explanation for these differences, social class is the key factor; cultural variables have little effect. Our findings support a theoretical framework attending to intersections among ethnicity, gender, and class. 相似文献

Cohabitation has become part of the pathway toward marriage. Prior work focuses on expectations to marry and has ignored cohabitation. Although most young adults are not replacing marriage with cohabitation, but instead cohabit and then marry, it is important to study adolescents’ joint expectations to cohabit as well as marry. Our analyses draw on recently collected data from the Toledo Adolescent Relationships Study (N = 1,293). We find that adolescents are less certain about their cohabitation than marriage expectations. Dating and sexual experience, traditional values, prosocial activities, and parents influence adolescents’ union formation expectations. The findings from this work suggest that adolescents are including cohabitation as part of their future life trajectories but rarely envision cohabitation as substituting for marriage. 相似文献

把与交通基础设施发展相关的权力进行分类,提出权力时空尺度的概念,并把权力的时空尺度具体化为权力主体与客体的时间尺度和空间尺度。从时空的角度形成中央与地方政府关系对公共资源配置影响的解释框架,通过逻辑推理和实证研究的方法对理论进行验证,可知在交通基础设施发展中,权力主体与客体的时空关系在很大程度上决定着公共资源的配置效率,通过权力的尺度重组分别实现事权、财权、行政首长任免权和监督权主、客体时空尺度的匹配,有助于提高公共资源的配置效率。我国目前应进一步完善基层人大制度,在更大程度上实现地方政府与当地公众的激励相容;进一步加强中央政府对地方政府的合法性监督。 相似文献

医疗卫生资源的分配是一个世界性难题,其面临着公平与效率、正当与善、政府与市场的伦理困境。而且,我国医疗卫生资源的分配机制并不完善,存在着总量不足、分配不均衡、服务质量差等问题。想要完善我国医疗卫生资源分配机制,我们必须在公平配置的目标指向下,从政府、医疗机构、社会成员、制度监督等各个方面入手,争取最大限度实现资源优化配置。 相似文献
