Costing Constitutional Change: Estimating the Cost of Five Variations on Australia's Federal System

Australia's system of government is by far the most centralised of the four 'classic' federations, hosting extremely centralised states, exceptionally weak local governments, and little of the substantive decentralisation and subsidiarity often presumed to derive from a federal structure. Five variations on the present structure are examined to estimate the costs of improved decentralisation, including New States models as traditionally advocated, Regional States models based on the ACT combined state–local prototype, and a National–Local model comprising a strengthened national government and local governments in essentially their present form. 1 Results indicate that the Regional States or National–Local models could deliver greater decentralisation while saving over $20 billion per annum compared to the present system. Generally, the analysis suggests that coherent modelling of alternative government structures may be more feasible than previously thought.     

Factors Contributing to Gender Differences in Depressive Symptoms: A Test of Three Developmental Models

In a longitudinal study on 115 early adolescents, the impact of major events, relationship stressors, and coping style in interaction with biological changes on depressive outcome in late adolescence were explored. Three developmental models proposed by Nolen-Hoeksema and Girgus (1994, Psychol. Bull. 115: 424–433), which attempt to explain the emergence of gender differences in adolescent depressive symptoms, were tested. Multiple regression analyses conducted to test Model 1 identified two etiological factors associated with gender differences of depression, namely, stress in the adolescent–mother relationship and a more negative body image. Tests of Model 2 revealed etiological factors which correlated with depression in adolescent girls but not adolescent boys. The correlational patterns of avoidant coping and body image emerged as relevant factors for Model 2. Finally, tests of Model 3 searched for factors which were more likely to be observed in adolescent girls than boys and which would put girls at risk should they interact with a third etiological factor. Early maturational timing emerged as a factor for Model 3.     

Committee characteristics and re-election margins: An empirical investigation of the US House

Models of legislative organization frequently begin with the premise that the committee system serves the re-election interests of incumbent legislators. Attempts to substantiate this notion empirically have been unsuccessful. Nevertheless, the notion lives on, nourished by a stylized characterization of the committee system. In the standard model committees have jurisdictional monopolies over specialized policy areas and legislators gravitate toward those committees that deal most closely with the policy concerns of their constituents. Contrary to this simplifying characterization, the degree of monopoly control and policy specialization varies across standing committees in the us congress. Some committees have wide jurisdictions and attract members with diverse policy preferences. Jurisdictional overlap and resulting turf battles are common aspects of congressional sessions. We suggest here that these realities warrant a re-opening of the empirical investigation into the link between electoral success and committee characteristics. Our findings indicate that assignment to a committee with a relatively high degree of monopoly control increases a member's vote share, and that assignment to a narrowly focused (specialized) committee does not.     

Social representation

Abstract This paper examines social representation in the European Parliament using a model which uses the demand, the supply and the structure of opportunities as factors explaining differential recruitment. Analysis of the experiences of candidates suggest that supply–side factors proved more strongly related to candidates gaining winnable seats than demand–side factors. Results also confirm the importance of institutional structures in widening or narrowing opportunities, and suggest the European Parliament will remain social unrepresentative in the foreseeable future, a characteristic that serves only to add to the already considerable problems of legitimacy in the European Union.     

Pulmonary arterial fibromuscular dysplasia: a rare cause of fulminant lung hemorrhage

Arterial fibromuscular dysplasia (FMD) represents a collection of noninflammatory and nonatherosclerotic vascular diseases with a poorly understood etiology. Classically occurring in renal and cerebral arteries, this entity has also been reported in coronary, carotid, and other medium and small arteries. One case occurring in the pulmonary vasculature has been reported. Fatal hemothorax and lung hemorrhage have multiple causes, including other vascular malformations and connective tissue disorders; however, cases of pulmonary FMD are exceedingly rare. We report what appears to be the second such association, occurring in a 69-year-old man. The patient presented with a 3-week history of increasing dyspnea, fatigue, and productive cough; 3 days of increasing back and chest pain; and syncope. Chest radiograph showed a "white-out" of the left lung. The patient died shortly after admission from a fulminant respiratory disease of undetermined etiology. At autopsy he was found to have a massive left hemothorax resulting from an unsuspected pulmonary arterial fibromuscular dysplasia.
