Everybody Loves a Winner: On the Mutual Causality of Presidential Approval and Success in Congress

A large literature argues that approval affects presidential legislative success, but Washington observers often believe that legislative success leads to higher presidential approval ratings, that is, success and approval may be endogenous. This article tests for the endogeneity of approval and success. After building a theory that links success to higher approval, annual aggregate data from 1953–2011 are used to test for the endogeneity between approval and success. All statistical tests indicate that approval and success affect each other. This article concludes by putting the findings into perspective and suggesting new research directions.     

Fifty Years Since Lashley's In Search of the Engram: Refutations and Conjectures

In his well-known article “In Search of the Engram” published in 1950, Karl Spencer Lashley summarized his 33 years of research and theory on memory and the brain. He concluded that (1) memories are not localized but are instead distributed within functional areas of the cortex and (2) memory traces are not isolated cortical connections between inputs and outputs. Though not the first time he had expressed such convictions, their reiteration in this article was backed by Lashley's estimable reputation and expressive power and they have taken firm root in the collective knowledge of today's memory and neuropsychological research community.     

Scientific strategists in the period of mamlakhtiyut: Interaction between the academic community and political power centers

In the first decades of the State of Israel an elitist group of scientists and scholars from academic institutions organized itself into a powerful status group. Its members participated in the establishment and development of programs and processes that had a significant impact on Israeli society. The power of this group (which we term “scientific strategists”) derived from personal and institutional cooperation between its members and leading political figures who had a strong influence on its agenda. This interaction was based on mutual trust and loyalty and contributed to establishing the infrastructure for the main political tradition at that time – mamlakhtiyut (the centrality of state interests). The article examines the activities of the scientific strategists, their ability to participate in government institutions without forfeiting their academic bases, and the ways in which political leaders promoted their symbolic status, financially supported their scientific activity, and endowed them with rewards and public recognition.     

An Introduction to Spatial Discounting

Research on the valuation of environmental externalities shows that decision makers tend to discount not only over time but across space. Just as time discounting has implications for intergenerational equity, geographical or spatial discounting has implications for intragenerational equity. Similarly, just as positive time discount rates are warranted by positive net rates of growth of the capital stock, positive spatial discount rates may be warranted by the fact that enviironmental (or other external effects of economic activity are diffused at positive rates. This paper introduces the notion of spatial discounting and explores its welfare implications through a simple diffusion model.     

Resettlement,Opium and Labour Dependence: Akha–Tai Relations in Northern Laos

Forestry is a major source of revenue for the Lao People’s Democratic Republic. The Government’s view is that shifting cultivation in the highlands is the primary cause of deforestation and erosion; this has led it to establish a policy of eliminating shifting cultivation by the resettlement of highland people in or near the lowlands. Here, it is assumed, the highlanders will be able to lead a more sedentary existence, cultivate wet rice, and benefit from various forms of development assistance. In the district of Muang Sing in northern Laos this policy has been partly responsible for the movement of large numbers of Akha people downhill to settle on the lower slopes of the highlands, at the periphery of the lowlands. This movement has been further encouraged by the low productivity of the Akha swidden economy. This article argues that Akha expectations of a more secure livelihood have not been fulfilled due to the ravages of disease, high rates of opium addiction, and the lack of government assistance. Instead, the Akha of the lower slopes have become an impoverished labour force, exploited for the benefit of the politically and economically dominant Tai lowlanders.
