Information economics as mainstream economics and the limits of reform: what does the Stiglitz Report and its aftermath tell us?

In this paper we use the Stiglitz Report of 2009/2011 as a point of departure to explore the way the development in economics theory provides a limited contribution to further reform. In so doing we provide a detailed analysis of potential underlying problems of information-theoretic economics. We note this provides an additional way to consider Thomas Palley’s concept of Gattopardo economics

Spontaeneous subacute portomesenteric venous thrombosis: a case report

Although uncommon and often asymptomatic, portal venous thrombosis can have catastrophic consequences for the individual it afflicts, particularly when the process propagates to involve the superior mesenteric vein. Familiarity with the condition's pathogenesis and presentation however permits early diagnosis and allows aggressive conservative management to achieve a successful outcome. Here we describe the successful outcome of such management for a 42-year-old male patient who developed this condition spontaneously

Marxism and science studies: a sweep through the decades

This paper outlines the distinctive contribution of marxism to science studies. It traces the trajectory of marxist ideas through the decades from the origins of marxism to the present conjuncture. It looks at certain key episodes, such as the arrival of a Soviet delegation at the International History of Science Congress in London in 1931 as well as subsequent interactions between marxists and exponents of other positions at later international congresses. It focuses on the impact of several generations of marxists who have engaged with science in different ways. It examines the influence of marxism on contemporary trends in science studies. It concludes that marxism survives in circuitous and complex ways. It argues not only for a positive interpretation of its contribution in the past but for its explanatory and ethical power in the present and future

J D Bernal: philosophy, politics and the science of science

This paper is an examination of the philosophical and political legacy of John Desmond Bernal. It addresses the evidence of an emerging consensus on Bernal based on the recent biography of Bernal by Andrew Brown and the reviews it has received. It takes issue with this view of Bernal, which tends to be admiring of his scientific contribution, bemused by his sexuality, condescending to his philosophy and hostile to his politics. This article is a critical defence of his philosophical and political position

Pathway of protection: Ethnic identity, self-esteem, and substance use among multiracial youth

Fifty percent of adolescents have tried an illicit drug and 70% have tried alcohol by the end of high school, with even higher rates among multiracial youth. Ethnic identity is a protective factor against substance use for minority groups. However, little is known about the mechanisms that facilitate its protective effects, and even less is known about this relationship for multiracial youth. The purpose of the present study was to examine the protective effect of ethnic identity on substance use and to determine whether this relationship operated indirectly through self-esteem, a strong predictor of substance use for among adolescent populations. Participants included 468 multiracial youth in grades six through 12 (53% female). The results found that ethnic identity was indeed related to substance use, partially through changes in self-esteem. Findings from this study contribute to our understanding and development of models of risk and protection for an understudied population

Cognitive Defusion Versus Thought Distraction: A Clinical Rationale, Training, and Experiential Exercise in Altering Psychological Impacts of Negative Self-Referential Thoughts.

Using two modes of intervention delivery, the present study compared the effects of a cognitive defusion strategy with a thought distraction strategy on the emotional discomfort and believability of negative self-referential thoughts. One mode of intervention delivery consisted of a clinical rationale and training (i.e., Partial condition). The other mode contained a condition-specific experiential exercise with the negative self-referential thought in addition to the clinical rationale and training (i.e., Full condition). Non-clinical undergraduates were randomly assigned to one of five protocols: Partial-Defusion, Full-Defusion, Partial-Distraction, Full-Distraction, and a distraction-based experimental control task. The Full-Defusion condition reduced the emotional discomfort and believability of negative self-referential thoughts significantly greater than other comparison conditions. The positive results of the Full-Defusion condition were also found among participants with elevated depressive symptoms

Acetylcholinesterase activity measurement and clinical features of delirium

Aims: Cholinergic deficiency is commonly implicated in the pathophysiology of delirium. We aimed to investigate the relationship between directly measured serum AChE activity and (1) clinical features of delirium and (2) outcomes, among older hospital patients with delirium. Methods: Hospitalized patients with delirium were recruited and delirium motor subtype, severity and duration of delirium were measured. Serum AChE activity was measured using a colorimetric assay. Results: The mean AChE activity for the whole sample was 2.46 μmol/μml/min (SD 1.75). Higher AChE activity was associated with increased likelihood of hypoactive delirium rather than the hyperactive or mixed subtype (OR 1.98, CI 1.10-3.59). Conclusion: Higher AChE activity was associated with hypoactive delirium, but did not predict outcomes. Simple enhancement of cholinergic neurotransmission may not be sufficient to treat deliriu
