Constituency characteristics and legislative preferences

An important concern for testing any theory of legislative politics is how to measure legislative preferences. No existing measures are immune to criticism, so sound advice should be based on a balanced assessment of various types of measures. This study focuses on the ability of constituency characteristics to predict Senate roll call votes. Even in the best possible case, constituency-characteristic measures are shown to be deficient both absolutely and relative to supposedly crude, vote-based measures which as ADA ratings. The implication is that constituency-characteristic measures are inappropriate as direct measures of legislative preferences. However, the possibility remains that for some applications they are useful indirect measures, e.g., as right hand side variables that covary with legislative behavior of interest.     

Conflict,collusion and corruption in small-scale gold mining: Chinese miners and the state in Ghana

As gold prices soared from 2008 onwards, tens of thousands of foreign miners, especially from China, entered the small-scale mining sector in Ghana, despite it being ‘reserved for Ghanaian citizens’ by law. A free-for-all ensued in which Ghanaian and Chinese miners engaged in both contestation and collaboration over access to gold, a situation described as ‘out of control’ and a ‘culture of impunity’. Where was the state? This paper addresses the question of how and why pervasive and illicit foreign involvement occurred without earlier state intervention. Findings indicate that the state was not absent. Foreign miners operated with impunity precisely because they were protected by those in authority, that is, public officials, politicians and chiefs, in return for private payments. Explaining why state institutions failed in their responsibilities leads to reflection about the contemporary state in Ghana. It is concluded that the informality and corruption characteristic of neopatrimonialism remains predominant over legal–rational structures, albeit in a form that has adapted to neoliberal restructuring. Public office remains a means of private enrichment rather than public service. Such findings cast a shadow over the state and government in Ghana, and tarnish its celebration as a model of democratic governance for Africa.     

Fixed-dose isosorbide dinitrate-hydralazine: race-based cardiovascular medicine benefit or mirage?

Race is not a scientific category, but African Americans have increased prevalence and severity of heart failure. The African American Heart Failure trial showed the benefit of a combination of isosorbide dinitrate (a nitric oxide donor) and hydralazine (an antioxidant). Future research may unmask the reason for cardiovascular differences in therapy.
