THE RELATIONSHIP BETWEEN SELF‐CONTROL AND LANGUAGE: EVIDENCE OF A SHARED ETIOLOGICAL PATHWAY*

Converging lines of research suggest that self‐control and language may be inextricably linked. No empirical research has ever examined this proposition, however. We address this gap in the literature by analyzing a sample of twin pairs from a nationally representative data set of children. The results revealed three broad findings. First, diminished language skills were predictive of low self‐control both cross‐sectionally and longitudinally. Second, the covariation between language and self‐control was linked to both genetic and environmental factors. Third, after controlling for genetic influences on self‐control, language skills were predictive of variation in individual levels of self‐control. The theoretical implications of these findings are discussed.     

Structural Adjustment and Political Adaptation: The Politics of Neoliberal Reform in Mexican Agriculture

Through a study of recent policy change in Mexico, this article shows that even a strong state, implementing a radical reform via purportedly neutral policy changes, inevitably must adapt to a context shaped by previous policy choices and outstanding political imperatives. In this case, the prior organization of commercial export growers in the fresh fruit and vegetable subsector, the strength of an independent peasant movement, and the state's long-term commitment to a rhetoric of development and social welfare significantly qualify the reform effort. In the export sector, Mexican production is largely shaped by the still powerful Confederation of Growers of Fruits and Vegetables. In regard to peasant agriculture, the government has had to make significant concessions to independent peasant organizations in an effort to regain political support. The neoliberal program has thus been qualified and to some extent reshaped by both immediate political considerations and the longer-term institutional and political structures of Mexican society. In this sense, economic forces remain "embedded" in prior social structures and political choices.
