ABSTRACTIn 2013, after nearly two decades of operating in a distributed legacy Integrated Library System (ILS) environment on local servers, the Orbis Cascade Alliance, a consortium of public and private academic libraries in Washington, Oregon, and Idaho, began a two-year-long process to migrate its 37 members to a shared implementation of Ex Libris's cloud-based Alma library management system (LMS) and Primo discovery interface. Although much has been written on electronic resource management (ERM) functionality at an institution level, little has been written on serials and ERM functionality and workflows within a shared consortial environment. This article discusses the challenges and opportunities of implementing a consortial-based LMS, with particular emphasis on serials and ERM functionality. Key migration issues related to serials control, acquisitions, licensing, administration, cataloging, statistics, and interoperability are examined at the institutional and large-scale networked levels. Benefits and limitations of using a shared consortial cloud-based LMS are explored, and the overall capabilities of the Alma LMS for electronic resource management are reviewed. 相似文献

A generalization of Zellner's SUR model is derived for sets of seemingly unrelated systems of econometric equations. The resulting structural form – worked out for a set of Cowles Commission-type simultaneous equations systems – is general enough to include any SUR-type or panel-type specification of systems of econometric equations with contemporaneously correlated errors. Maximum estimation efficiency is obtained by treating all the individual subsystems at once rather than in a subsystem-by-subsystem fashion. 相似文献

Progressively Type-II censored conditionally N-ordered statistics (PCCOS-N) arising from iid random vectors Xi = (X1i, X2i, …, Xip), i = 1, 2…, n, were investigated by Bairamov (2006), with respect to the magnitudes of N(Xi), i = 1, 2, …, n, where N( · ) is a p-variate measurable function defined on the support set of X1 satisfying certain regularity conditions and N(Xi) denotes the lifetime of the random vector Xi, i = 1, …, n. Under the PCCOS-N sampling scheme, n independent units are placed on a life-test and after the ith failure, Ri (i = 1, …, m) of the surviving units are removed at random from the remaining observations. In this article, we consider PCCOS-N arising from a vector with identical as well as non identical dependent components, jointly distributed according to a unified elliptically contoured copula (PCCOSDUECC-N). Results established here contain the previous results as particular cases. Illustrative examples and simulation studies show that PCCOSDUECC-N enables us to analyze the lifetime of several systems, including repairable systems and systems with standby components, more efficiently than PCCOS-N. 相似文献

Social workers are better equipped to understand the need to incorporate geographical aspects pertaining to their clients’ lives as part of their practice, given the significant influence these factors have on client well-being. Geographic Information Systems (GIS) technology is a useful tool for administrators and planners to make informed decisions regarding human service programs including examining program outcomes and impact as well as streamlining program implementation. This article synthesizes the literature to date on GIS in health and human services with examples of real world applications. 相似文献

Relative to White families, Black families have been described as relying on extended social networks to compensate for other social and economic disadvantages. The presence or absence of supportive social networks should be especially relevant to young couples entering marriage, but to date there has been little effort to describe the social networks of comparable Black and White newlyweds. The current study addressed this gap by drawing on interviews with 57 first‐married newlyweds from low‐income communities to compare the composition and structure of Black and White couples' duocentric social networks. The results indicated that low‐income Black couples entered marriage at a social disadvantage relative to White couples, with more family relationships but fewer positive relationships and fewer sources of emotional support (for wives), fewer connections to married individuals, and fewer shared relationships between spouses. Black couples' relative social disadvantages persisted even when various economic and demographic variables were controlled. 相似文献

Although the organizational structures and operating procedures of state substance abuse prevention systems vary substantially across states, there is scant empirical research regarding approaches for rigorous assessment of system attributes and which attributes are most conducive to overall effectiveness. As one component of the national cross-site evaluation of the SPF State Incentive Grant Program (SPF SIG), an instrument was developed to assess state substance abuse prevention system infrastructure in order to measure infrastructure change and examine the role of state infrastructure in achieving prevention-related outcomes. In this paper we describe the development of this instrument and summarize findings from its baseline administration. As expected, states and territories were found to vary substantially with respect seven key characteristics, or domains, of state prevention infrastructure. Across the six domains that were assessed using numeric ratings, states scored highest on data systems and lowest on strategic planning. Positive intercorrelations were observed among these domains, indicating that states with high capacity on one domain generally have relatively high capacity on other domains as well. The findings also suggest that state prevention infrastructure development is linked to both funding from state government and the presence of a state interagency coordinating body with decision-making authority. The methodology and baseline findings presented will be used to inform the ongoing national cross-site evaluation of the SPF SIG and may provide useful information to guide further research on state substance abuse prevention infrastructure. 相似文献

Working with survivors of trauma is mostly challenging, exhausting, long‐term and often ‘messy’, when interventions that ‘should’ work, don't, or the unexpected arises. Nevertheless, explanations that speak to recovery from trauma more and more rely on neurobiological concepts to account for any positive change. Combining the family systems approach of Murray Bowen and recent research on the brain and trauma, post trauma symptoms are viewed as part of the ‘family emotional process’ even when traumatic events have emanated from outside the family system itself. Variations in responses to trauma, including dissociation and self‐harm are discussed in relation to chronic anxiety and ‘differentiation of self’. 相似文献

The Brazilian organic food sector has experienced important growth during the last two decades. Brazilian smallholders, however, are facing huge challenges to enter and benefit from this growth in a sustainable way. Combining the lens of New Institutional Economics and socio-anthropology, we analyze six experiences of Brazilian smallholders who converted to organics in the 1990s’. Three different food systems are featured in this analysis: an alternative food system, which is strongly interwoven with the Brazilian Agro-ecological movement and two commercial food procurement systems oriented towards domestic and an export markets driven mainly by supermarket chains. The analytical focus was on 1) the governance of these food systems, 2) the constraints farmers are facing within these food systems and, 3) the benefits that they can expect from market inclusion. We highlighted the roles that NGOs, Faith-based organizations and public-related agencies play in supporting the inclusion of smallholders into all three food systems. We confirmed the arguments in support of pursuing the agro-ecological development based model in Brazil, but underlined that there is a critical lack of support for farmers included in the commercial market-oriented food systems. Such a lack is even more critical as the food systems driven by expanding supermarket chains are characterized by strong asymmetric power relations at the expense of smallholders. Considering the reluctance of NGOs and Faith-based organizations to support these farmers, we call for efforts to be made to provide a policy framework to enable public-related entities to secure sustainable inclusion into these systems and exit strategies for those experiencing exclusion from these highly competitive food systems. 相似文献

This study uses ethnographic research to examine the phenomenon of transnational parenting by migrant mothers from the African Caribbean community and their family who care for the mothers’ children. Twenty women’s narratives demonstrate the complexity of relationships between migrant mothers living and working in New York City and their extended family or kinship caretakers who coparent their children in their countries of origin. The study reveals three main factors that contribute to the success of transnational parenting: (1) informal kinship care-child fostering, (2) remittances, and (3) social networks. Policy and practice implications are explored. 相似文献

This paper is a personal account of my own family of origin research. It explores the impact of separations from parents, nuclear family, and extended family through a Bowen family systems theory perspective using concepts pertaining to Bowen theory such as chronic anxiety, differentiation of self, multigenerational family process, and the emotional system. An outline of the process of doing research in ‘vivo’ with my mother as well as conversations with my supervisor are included. Theoretical differences between individual and system models are discussed. A Bowen theoretical approach to the anxiety of separations is investigated. The efficacy of engaging in family of origin work and the effects of thinking systems is examined in light of how it assisted me to view family members, family system disturbances, and clients’ emotional systems more objectively. 相似文献
