The knowledge of caring: revisiting the need for knowledge support of carers

Foster carers' knowledge of caring for abused and neglected children is a largely under-researched area. We know very little about the nature of carers' knowledge in relation to caring for children who have been abused or neglected. This paper reports on an exploratory study which examined the knowledge of caring. Qualitative data were analysed based on in-depth interviews with 10 foster carers in Queensland, Australia. A range of knowledge was identified showing an interaction of both personalized and formal understandings in the caring response. Given the breadth of knowledge recognized from the analysis, this paper presents one dimension of their knowing: theory and abuse-indicated understandings. Participants' responses in these areas were at times sound, but many struggled to provide convincing and well-formed explanations of topics, such as attachment, harm and child development which may suggest that their understandings are not what they could be. Although further research is needed on a larger scale, this study does highlight the necessity to re-examine processes and strategies for carer knowledge support, so as to strengthen their understanding of these issues.     

Parental Expenditures on Children's Education

This study examined selected factors related to parents' allocation of money for children's primary and secondary education and, if money was spent on education, the variation in the amount spent. Cragg's double-hurdle model was utilized to analyze data from the 1996 Consumer Expenditure Survey on 331 families that spent money on their children's primary and secondary education and 827 families where parents reported no such expenditures. Factors that were significantly related to spending money on children's primary and secondary education, included after-tax income, parent's education, region, and season of the year. Variables significantly related how much was allocated to children's primary and secondary education, included after-tax income, parent's education, age, and race.     

Measuring underemployment and inequality in the work force

In a recent article in this journal, Tipps and Gordon (1985) presented new indicators of underemployment and compared them to indicators obtained from the Labor Utilization Framework (LUF) of Hauser, Sullivan, Clogg, and others. In this note the Tipps-Gordon criticisms of LUF are reviewed, the Tipps-Gordon framework is criticized, and both LUF and the Tipps-Gordon approach are compared empirically as well as conceptually. An extension of LUF is also presented.     

Returns to Schooling in Spain: How Reliable are Instrumental Variable Estimates?

This paper studies the ordinary least–squares (OLS) and instrumental variable (IV) estimates of the returns to schooling for male workers in Spain. OLS estimates are often biased due to the endogeneity of schooling, measurement errors or omitted variables. Proper IV estimates correct this bias. The reliability of family background, natural experiments (based on changes in the education system and season of birth) and the availability of a college in the province is checked using Spanish data. The results suggest that background and college availability are valid instruments and that the IV estimates of the returns to schooling are higher than OLS estimates. These results are in line with the majority of previous results in the literature.     

The influence of top management support for ICTs on organisational performance through knowledge acquisition,transfer, and utilisation

This research analyses, first, whether top management support for information and communications technologies has positive consequences for knowledge management by analysing the specific influence of top management support for ICTs on each of the knowledge management processes (knowledge acquisition, transfer, and utilisation). Second, it analyses the influence of each knowledge management process on organisational performance. The theoretical model is tested using data collected from March to May 2010 from 201 CEOs in Spanish technology organisations. The results indicate that the stage-based disaggregation of the knowledge management process into knowledge acquisition, transfer, and utilisation, and the three-stage management process are the mediating mechanisms in the relationship between top management support for ICTs and organisational performance. CEOs should thus support the information and communication technologies necessary to improve all of the interrelated stages of knowledge management as a mechanism for achieving better organisational performance. Various strategic actions should be stimulated within the organisation to intensify the interrelation between these stages of acquisition, transfer, and utilisation of knowledge.     

Recent progress in mathematics and engineering on optimal graph labellings with distance conditions

The problem of radio channel assignments with multiple levels of interference can be modelled using graph theory. The theory of integer vertex-labellings of graphs with distance conditions has been investigated for several years now, and the authors recently introduced a new model of real number labellings that is giving deeper insight into the problems. Here we present an overview of the recent outpouring of papers in the engineering literature on such channel assignment problems, with the goal of strengthening connections to applications. Secondly, we present a new contribution to the theory, the formulas for the optimal span of labellings with conditions at distance two for finite complete bipartite graphs. Dedicated to Professor Frank K. Hwang on the occasion of his 65th birthday. Research supported in part by NSF grants DMS-0072187 and DMS-0302307. An early version of this paper was presented at the CTS Conference on Combinatorics and its Applications in May, 2005, at Chiao Tung University, HsinChu, Taiwan. The first author is grateful to the CTS for its support of his travel.     

Navigating Americanized Identities: Bicultural Ethnicity,Race, and the Incorporation Experience

This paper reports on the complex ways in which immigrant young adults make sense of their Americanized ethnic and racial identities. The analysis draws on a large set of in-depth interviews (N?=?233) collected with immigrants between the ages of 18 and 29 across three regions in the US (California, New York, and Minnesota) in the early 2000s and is in dialogue with emerging new theories of immigrant incorporation which combine the insights of traditional assimilation and racialization frameworks. The identity narratives that emerge from these interviews demonstrate the overarching significance of racial and ethnic identification for young adults across various immigrant communities. The narratives also highlight some of the contextual factors involved in the construction of an ethnic identity in the US such as experiences with discrimination; or the presence of co-ethnic communities. The final substantive section explores how young American immigrants in the transition to adulthood attempt to cultivate hybrid, bicultural identities that balance their American-ness with the ongoing experience of living in a deeply racialized society. The paper concludes by discussing implications for the literature on identity formation and the transition to adulthood as well as on the immigrant incorporation experience.     

Complementarity of pensions and training under multiemployer plans

We compare firmoptimizing and institutional models of labor contracts to investigate how different types of pension plans affect employee training. Unlike previous stud-ies, we consider an expanded voice model of training and pension coverage in which worker and union preferences feed back on firm decisions, and we test for this bidi-rectional causality between pensions and training. A standard view is that firms pro-vide pensions to optimize their training costs. However, when pension coverage is treated as endogenous in a twostage least squares regression (the data are merged 1991 CPS samples), pensions have a negative effect on training. In contrast, when the pension is a definedbenefit, multiemployer plan, training and pensions are comple-ments, consistent with both optimizing and institutional models. We are grateful for excellent research assistance from Michael Ash, Bhashkar Mazumder, and Judith Ruha and for suggestions from Dale Belman, David Card, B.J. Lee, David MacPherson, and John Turner.
