Few empirical studies have examined the effect of personal values on the importance attached by individuals to training and development in organizations. We argue that personal values play an important role in decision-making processes (i.e. commitment to training and development) and that such values are the product of socialization processes operating at an organizational and societal level. Questionnaire data were collected from 340 Irish and Canadian line managers to test the hypothesis that personal values affect the importance attached by respondents to training and development. Capability values were found to be a significant positive predictor of the perceived importance of training and development. The findings emphasize the need for simultaneously examining both personal values and organizational factors as predictors of training and development activity.  相似文献

This article examines the governance of globally distributed knowledge work. To measure performance in knowledge work, it is important to focus on what the knowledge workers do and hence view knowledge as something one does, namely the practices, instead of something one has. By following the practices of knowledge work, it was possible to evaluate the effect of measures related to organizational processes, and identify what was not well covered by the measurement tool. Strategic and long term needs such as learning and employee competence are better managed through projects. This article shows how work performance in international organizations needs two different measures: one tool for measuring short-term value creation linked to the organizational processes; and, one tool for measuring long-term value creation linked to the practices of service work made in projects. Global governance of distributed employees is therefore successfully managed through key performance measures and through understanding projects through their multiple contributions, at both an individual and an organizational level. Global long term governance needs are strategic for the entire firm. The paper rests on an in-depth empirical case study of an international professional service firm.  相似文献

We consider the frugal coverage problem, an interesting variation of set cover defined as follows. Instances of the problem consist of a universe of elements and a collection of sets over these elements; the objective is to compute a subcollection of sets so that the number of elements it covers plus the number of sets not chosen is maximized. The problem was introduced and studied by Huang and Svitkina (Proceedings of the 29th IARCS annual conference on foundations of software technology and theoretical computer science (FSTTCS), pp. 227–238, 2009) due to its connections to the donation center location problem. We prove that the greedy algorithm has approximation ratio at least 0.782, improving a previous bound of 0.731 in Huang and Svitkina (Proceedings of the 29th IARCS annual conference on foundations of software technology and theoretical computer science (FSTTCS), pp. 227–238, 2009). We also present a further improvement that is obtained by adding a simple corrective phase at the end of the execution of the greedy algorithm. The approximation ratio achieved in this way is at least 0.806. Finally, we consider a packing based algorithm that uses semi-local optimization, and show that its approximation ratio is not less than 0.872. Our analysis is based on the use of linear programs which capture the behavior of the algorithms in worst-case examples. The obtained bounds are proved to be tight.  相似文献

The article explores the figure of the “good bandit,” connecting representations of the historical personage Ghino di Tacco in late-medieval Italian literature with the bandits in Washington Irving’s travel tales. Ghino di Tacco was a notorious bandit, known for raiding pilgrims and travelers in thirteenth-century Tuscany. Nevertheless, according to literary sources such as Boccaccio's Decameron, the infamous raider left his victims unharmed and with the means necessary to complete their journeys. Sources also indicate that Ghino di Tacco became a bandit because of factional disputes and was eventually pardoned by Pope Boniface VIII for healing the Abbot of Cluny. Similarly, the fictional bandits in Irving’s Tales of a Traveller (1824) are revealed to be men of moral standing, forced into a violent life of banditry in response to the excesses of nineteenth-century Italy’s ruling classes. His tales redeem the figure of the bandit from crude one-dimensional treatments common in the works of English writers such as Ann Radcliffe. Pivoting from established proposals that have characterized bandits as either criminals or revolutionaries, this article argues that, for Boccaccio as with Irving, the figure of the good bandit functions as a symbol of reconciliation and social reintegration.  相似文献

Adoption in Brazil has long been related to practices of not disclosing the child's history and origins, which become a family secret. As a consequence, most couples who apply for adoption prefer newborns. Late adoption is still an uncommon practice and requires a 'family project' which accepts a different family model, new meanings of motherhood and fatherhood, and different ways of building affectionate bonds. It is important to investigate how a man and a woman become parents under those circumstances. This study aimed to follow up the emergence of adoption, motherhood and fatherhood meanings, in the discursive practices involved in the construction of adoptive parenthood in the Brazilian setting. This paper presents important meanings regarding parenthood produced by a couple who adopted two sisters, aged 4 and 5 years. Analysis revealed that to better understand the late adoption process, the meanings that emerge in the discursive practices should be considered. Those meanings pervade and circumscribe the family relationships, influencing how the individuals constitute their roles in the family. It is through the analysis of this dialogical process of construction that it is possible to identify the challenges in late adoption and to unravel the process of constructing affectionate relationships.  相似文献

Despite a delay of 20–25 years, when it comes to cohabitation, Italy has now begun to resemble other Western countries. In addition, the increase in legal separations has accelerated since 1995, although their number still remains far from that observed in countries such as the USA, the UK, and France. Finally, Italy’s fertility decline has come to a halt: the cohort of women born in the early 1970s will likely have the same TFR as those born in the mid-1960s (around 1.55). Moreover, in the Centre–North areas, period TFR rose from 1.1 in 1995 to 1.35 children per woman 10 years later. The territorial diffusion of cohabitation, legal separation, out-of-wedlock births, and fertility recovery overlaps closely with that of the decline in births during the first half of the twentieth century. A similar geographical pattern has been observed for the diffusion of school enrolment, industrialization, secularization, and (during the last 20 years) foreign immigration.  相似文献

While well chosen sampling schemes may substantially increase efficiency of observational studies, some sampling schemes may instead decrease efficiency. Rules of thumb how to choose sampling schemes are only available for some special cases. In this paper we provide tools to compare efficiencies, and cost adjusted efficiencies, of different sampling schemes, in order to facilitate this choice. The method can be used for both categorical and continuous outcome variables. Some examples are presented, focusing on data from ascertainment sampling schemes. A Monte Carlo method is used to overcome computational issues wherever needed. The results are illustrated in graphs.  相似文献

Media reports of the dangers of swine flu can leave much to be desired. But then scientific reports can be just as unclear. Diamanto Mamuneas and Maria Viskaduraki have sympathy for two journalists and help a frightened friend.  相似文献

Abstract

The purpose of this research is to help reduce tensions in supply chain social sustainability (SCSS) decisions by providing a common global, contextual definition of social sustainability. This exploratory study utilised an inductive structured interview method to capture SCSS concept meanings. Those interviewed are from, have lived, and worked in developed economies, emerging economies and the base of the pyramid (BOP) economies. The results present a new global baseline definition of SCSS to inform theory and practice by finding that SCSS meanings differ not only between the different levels of economic development, but also within the levels as well. Culture, community and whether basic human needs are met all weigh into perspectives of what this concept is and should entail; a broad, contingent definition is most appropriate moving forward for sustainability planning and execution. Further research with stakeholders in more countries and communities is needed to validate our proposal.  相似文献

We use data from a large scale and nationally representative survey to evaluate two narratives about the social bases of Brexit. The first narrative sees Brexit as a revolt of the economically left-behinds. The second narrative attributes Brexit to the resurgence of an English nationalism. There is some, albeit not always consistent, evidence that people in relative poverty or those living in areas that have seen greater Chinese import penetration are slightly more pro-Leave. People living in economically deprived neighborhoods are not more pro-Brexit. Using the Weberian class–status distinction, it is social status, not social class, which stratifies Brexit support. Individuals for whom being British is important are more pro-Leave. But those who see themselves as British rather than English, and those reporting omnivorous cultural consumption are less supportive of Brexit. Overall, there is empirical support for both narratives. But the weight of the evidence suggests a strong cultural dimension in Brexit support.  相似文献
