Histopathological changes in selenium-exposed fish

Redear sunfish (Lepomis microlophus) were collected from Martin Lake in east Texas. For at least 8 months, 1 year earlier, aqueous selenium-laden effluent from man-made sources was released into this 5,000-acre reservoir (unpublished data). Redear sunfish from a reference lake, 8 km upstream, were collected for comparison to Martin Lake fish. The hepatopancreas (i.e., liver and associated, disseminated exocrine pancrease), mesonephros (i.e., kidney), gonads, heart, spleen, stomach, and gill arches were preserved for histopathological examination using optical and/or transmission electron microscopy. Livers from Martin Lake redear sunfish (which had accumulated approximately 20 ppm selenium in the liver) showed central necrosis, reduced quantities of rough endoplasmic reticulum and glycogen particles, and increased numbers of lysosome-like structures. Kidneys showed proliferative glomerulonephritis, and exocrine pancreas showed marked hypertrophy at the optical level. Ultrastructurally, architectural disorganization, reduced rough endoplasmic reticulum, increased cisternal space, and proliferation of smooth endoplasmic reticulum were evident. The stomach, spleen, gill, heart, and gonads showed no abnormalities.

Police uniforms,attitudes, and citizens

This study focuses on identifying the relationship between the citizen's attitude toward the police and the police uniform and authoritarian attitude. The perceived authority associated with the police uniform has been an essential ingredient of the police role. Consequently, the police uniform influences attitudes and behaviors of the wearers as well as the citizens with whom they interact. The citizen's attitude is negatively affected by the traditional military style police uniform in conjunction with the authoritarian attitude exhibited by police officers in performance of their duties. Consequently, when the uniform and officer's attitude are altered, there will be a corresponding change in the citizen's attitude toward the police. The attitude of the officer, in conjunction with the uniform, exerts considerably more influence on the citizen's attitude than does the uniform, officer's attitude, or any additional factor acting independently.     

Self-reports of Police Speeding Stops by Race: Results from the North Carolina Reverse Record Check Survey

Survey reports of police stops and driving behavior are a potential methodology for examining the magnitude and prevalence of the “Driving While Black” phenomena. However, estimates of the magnitude or correlates of racial disparity in police stops from self-reported survey data are potentially compromised if the accuracy of self-reports of police stops and driving behavior differ by race. We report on the results of a reverse record check survey in which we directly assess the degree and consequences of differences by race in self-reports of police stops. In our sample of drivers who had been cited for speeding in the preceding year, we found that 77% of the White respondents and 71% of the African American respondents admitted to being stopped. While both groups underreport stops, African Americans do so at a higher rate. This finding is consistent with many past studies which report stronger social desirability effects on survey responses among African Americans. Thus, survey data will tend to underestimate the magnitude of the “Driving While Black” phenomena.

Institutional influences on business power: how ‘privileged’ is the Business Council of Australia?

• This paper explores the institutional and political dynamics of the Business Council of Australia (BCA), a unique form of big business association which relies on the active involvement of its one hundred or so CEO members. The paper argues that associations such as the BCA confront a range of serious institutional problems in their attempts to wield political power, or more modestly perhaps, policy influence. First, they confront a disconnect between ‘structural’ and ‘instrumentalist’ articulations of business power. The key source of business power resides in business control over the economy and the investment process, a form of power wielded at the company level not at the level of business associations. When engaged in instrumentalist or overt forms of political activism, the BCA also confronts serious collective action problems. It is also argued that the influence of the BCA seems to have declined over time and that this can partly be traced back to declining CEO commitment rooted in changing institutional and structural dynamics in the corporate world.
