Community exercise program for older adults recovering from hip fracture: a pilot study

Community-based rehabilitative exercise programs might be an effective means to improve functional outcomes for hip-fracture patients. The purpose of this study was to evaluate the effectiveness of a community exercise program (CEP) for older adults recovering from hip fracture. Twenty-five older adults (mean age 80.0 +/- 6.0 years; 24 women; 71 +/- 23 days post-hip fracture) participated in this pilot study (17 exercise, 8 control). The CEP involved functional stepping and lower extremity-strengthening exercises. Control participants received only standard outpatient therapy. Measures of functional mobility, balance confidence, falls efficacy, lower extremity strength, and daily physical activity were evaluated at baseline and at 16 weeks. Improvements for self-reported physical activity, mobility, balance, and knee-extensor strength were observed for the CEP group. This study demonstrated that a CEP is beneficial for community-dwelling older adults post-hip fracture.     

An alternate version of the conceptual predictive statistic based on a symmetrized discrepancy measure

The conceptual predictive statistic, C_p, is a widely used criterion for model selection in linear regression. C_p serves as an estimator of a discrepancy, a measure that reflects the disparity between the generating model and a fitted candidate model. This discrepancy, based on scaled squared error loss, is asymmetric: an alternate measure is obtained by reversing the roles of the two models in the definition of the measure. We propose a variant of the C_p statistic based on estimating a symmetrized version of the discrepancy targeted by C_p. We claim that the resulting criterion provides better protection against overfitting than C_p, since the symmetric discrepancy is more sensitive towards detecting overspecification than its asymmetric counterpart. We illustrate our claim by presenting simulation results. Finally, we demonstrate the practical utility of the new criterion by discussing a modeling application based on data collected in a cardiac rehabilitation program at University of Iowa Hospitals and Clinics.     

The changing structure of food retailing in europe: the implications for strategy

European food retailers have increased their scale and scope while concentrating sales into large stores. Strategic implications include the need for scale to compete and organisational relationships to move from supply push to demand pull retailing. Consequences are different for private label and for branded manufacturers, who must respond to the demands of retail supply chains whilst retaining control of product development. Further concentration in both sectors is likely. Consumers are more mobile, but more captive to the retailer in store. Public policy makers are challenged to find new measures of retail power and both allow for innovation and ensure equitable shopping opportunities.     

Exploring Neglected Dimensions of Social Policy: The SDW, Fiscal Welfare and the Exemplar of Local Taxation in England

Titmuss's Social Division of Welfare (SDW) thesis is a vitally important but much neglected element of social policy analysis. This article seeks to explore the SDW, with a particular focus on fiscal welfare. Fiscal welfare has been described as forming a hidden welfare state, and while taxation is one of the main ways in which governments affect the lives of citizens, studies of welfare pay remarkably little attention to its impact. Fiscal welfare is examined by using, as an exemplar, local taxation in England, a subject that itself is neglected within social policy. Local taxation in England is of interest because it illustrates the impact of a system of taxation on different groups of citizens, and how this can operate to the benefit of rich over poor citizens. This is because the current system is highly regressive, meaning that those on low and middle incomes spend proportionately more of their income paying the tax than do those on high incomes. What is of further interest is how within the debate about reform of local taxation, concern with regressivity becomes obscured and ceases to be the focus of attention. We are thus provided with an example of how fiscal welfare remains a hidden issue. The article concludes by arguing that social policy analysis needs to move beyond the narrow confines of social welfare and develop a broader understanding of welfare, based on the SDW.     

The effects of gender control on fertility and children's consumption

Effects of sex preference on investments in children‘s human capital, bequests and fertility are studied, with and without sex selection, in a model based on parental altruism. Both pure sex preference, a feature of the parental utility function, and indirect preference, which arises from gender-related differences in earnings opportunities, are examined. When there is no gender control the impact of pure sex preference is seen in smaller consumption for daughters than for sons. However, when gender control is exerted, sex preference raises the sex ratio and it is possible that sisters may, on average, consume no less than their more numerous brothers. In an example of the model with specific functional forms, parents who practise gender control have larger families than if sex selection techniques were unavailable. The effect is magnified if sons‘ earnings opportunities are better than daughters‘. JEL classification: D11, J13, J16 Received August 31, 1995 / Accepted May 2, 1996     

Police violence and judicial bias in the age of mass democracy: Glasgow, 1933–1935

Using the example of an impoverished, so-called ‘slum’ district in Glasgow, this article argues that poorer, working-class people were subjected to aggressive and frequently violent policing along with systematic hostility from the judiciary and the press in Britain during the 1930s. In Glasgow, attempts to challenge police methods and police officers’ courtroom testimonies met with a highly punitive response from the city’s legal establishment. Despite enjoying the rights of citizenship, working-class people found it difficult to find politicians to take up their complaints about police incivility and brutality, embodied in the conduct of a police constable known locally as ‘Hitler’. Those few politicians willing to do so, whether in Glasgow Corporation or in the House of Commons, found themselves marginalized as mainstream politicians of all parties refused to accept that the British police were capable of inflicting ‘terror’ on civilians. Press sympathy extended only to those working-class women jailed for perjury and separated from their children in the wake of trials of ‘rioters’ at Glasgow Sheriff Court. Human-interest coverage of the plight of their families gave working-class people a voice as victims of misfortune. They were not permitted to speak as victims of miscarriages of justice.
