The Impact of Music on Childhood and Adolescent Achievement*

Objective. The study examines the association between music involvement and academic achievement in both childhood and adolescence using three measures of music participation: in school, outside of school, and parental involvement in the form of concert attendance. Methods. We review prior work pertaining to music's impact on achievement and then draw from two nationally representative data sources (ECLS‐K and NELS:88). Our analyses apply logistic and OLS regression techniques to assess patterns of music involvement and possible effects on math and reading performance for both elementary and high school students. Results. Music involvement varies quite systematically by class, and gender status, and such involvement holds implications for both math and reading achievement, and for young children and adolescents. Notably, associations with achievement persist in our modeling even when prior achievement levels are accounted for. Although music does mediate some student background effects, this mediation is only minimal. Conclusions. Music participation, both inside and outside of school, is associated with measures of academic achievement among children and adolescents. Future work should further delineate the relevant processes of music involvement, as well as how background inequalities and music involvement intersect in relation to educational performance.     

THE DETAIL SCHEDULING OF A PART-TIME WORK FORCE: A CASE STUDY OF TELLER STAFFING

This paper presents a comparison of two heuristic methods for assigning a part-time work force to meet varying daily work loads. The authors use actual operating data from Purdue National Bank, Lafayette, Indiana, to make teller staffing decisions. The performance criteria for comparison of the two heuristics is the minimum number of workers employed, minimum number of interbranch transfers, and computer time necessary to attain a solution.     

Decision Analysis and Risk Management Decision Making: Issues and Methods

This paper provides an overview of decision analysis and its use in risk management decision making. The paper discusses the distinctive characteristics of decision analysis and compares these characteristics with those of its principal alternative—cost–benefit analysis. The paper also discusses each of the steps in a decision analysis and the strengths and limitations of the method.     

Colonial Military Garrisons as Labor-Market Shocks: Quebec City and Boston, 1760–1775

The military occupation of Boston in 1768 shocked the city's labor market. The soldiers, who were expected to supplement their pay by working for local businesses, constituted an influx equal to 12.5 percent of greater Boston's population. To assess the importance of this shock, we use the case of Quebec City, which experienced the reverse process (i.e., a reduction in the British military presence from close to 18 percent of the region's population to less than 1 percent). We argue that, in Boston, the combination of the large influx of soldiers and a heavy tax on the local population in the form of the billeting system caused an important wage reduction, while the lighter billeting system of Quebec City and the winding down of the garrison pushed wages up. We tie these experiences to political developments in the 1770s.     

Battles through and about statistics in French pay equity bargaining: The politics of quantification at workplace level

This article proposes to study the discreet ‘battles of numbers’ at workplace level, particularly exacerbated on pay equity, in relation to its potential additional costs for employers. Figures are at once a framework, an object and a resource for power struggles between social partners. This approach is inspired by ‘statactivism’, a research perspective that studies the ways and contexts in which statistics can become tools for social mobilization. In a European context where bargaining is increasingly decentralized to company level, we argue that researchers should pay attention to statistical resources and quantification skills of negotiators, both on the management and unions side. They should also include in their analytical framework the influence of experts and specialists who advise social partners on how to strategically produce and use gender‐sensitive statistics. In this article, two case studies allow us to open the ‘black box’ of equality bargaining, revealing challenges and controversies of gender pay reporting.     

POSTSTRUCTURALISM IN FAMILY THERAPY: INTERROGATING THE NARRATIVE/CONVERSATINAL MODE

The narrative/conversational mode of family therapy, based in constructivism and Batesonian cybernetics, has lately associated itself with the poststructuralism of Foucault and Derrida. The narrative/conversational models of White and Epston (1990) and de Shazer (1991) draw only selectively from Foucault and Derrida's ideas and so perpetuate the constructivist neglect of social context and power. Disregarded aspects of Foucault and Derrida's work do contribute to an under-standing of social context and power. Poststructuralism is a dubious prop for constructivist assumptions: its true merit is in its capacity to illuminate the political/cultural context of our practice, including family therapy as a social institution.     

Citizenship, poverty and the real will

The paper analyses the concept of citizenship in the work of Bernard and Helen Bosanquet against the backcloth of a broader intellectual and historical framework. The discussion then addresses three issues in relation to citizenship: class, markets and poverty. Each concept is introduced through the medium of T.H. Marshall's ideas on citizenship. Marshall's ideas are taken as broad markers for the discussion of the concept in the post 1945 era. The discussion of each concept is then analysed in relation to the Bosanquets’ theories. The basic conclusion is that many of the Bosanquets’ analyses and answers are both inappropriate and antique, however they do highlight certain intrinsic difficulties which are still very much part of twentieth century states.     

A Non-radial DEA Index for Peruvian Regional Competitiveness

In this paper, we propose a method to measure competitiveness performance at the subnational level, with an application to Peruvian regions. For this, we propose a benefit-of-the-doubt composite index that summarizes the information of several indicators that characterize competitiveness. It is based on an optimization approach, using data enveloping analysis (DEA) techniques, so that each indicator is weighted in an endogenous way, and each unit is evaluated in the most favourable light. Our proposed index is a non-radial variant of the typical DEA scores, which avoids the traditional pitfalls of DEA-based composite indices, such as unreasonable weights. Additionally, we propose a meta-frontier approach in order to compare the competitiveness performances across different periods of evaluation. Our assessments of the Peruvian regions’ competitiveness performance improve on the results of traditional DEA methods, which award high marks to regions with very heterogeneous performance (i.e., regions with very high scores in some indicators, and very poor in others). Additionally, the comparison of the performance across time shows a general decrease in the average competitiveness between 2008 and 2014 of the Peruvian regions.
