Congressional access to executive branch information: Lessons from Iran-Contra

The Iran-Contra affair highlights the ongoing contest between Congress and the President over access to information. To carry out their constitutional functions, each branch needs information and the ability to protect the disclosure of that information. In the case of Iran-Contra, legitimate protection of information was replaced by lies and deception on the part of Executive officials, the pursuit of contradictory policies by the Executive Branch, and the violation of congressional statutes. Congress was denied the information it needed to discharge constitutional responsibilities, requiring it to reassert legislative prerogatives by tightening oversight statutes and scrutinizing presidential nominees who had some involvement in Iran-Contra. As a result of prosecutions by the Independent Counsel, a number of Executive officials and private citizens who participated in Iran-Contra have already pled guilty or been found guilty by Federal juries. Other than some temporary mending of fences and promises of good-faith, it is uncertain whether Iran-Contra will yield more permanent and beneficial lessons.     

The Master Should Know More: Book-Farming and the Conflict Over Agricultural Knowledge

Eighteenth-century Britain witnessed a struggle over knowledge and expertise in agriculture that has been largely neglected. This article uses the social controversies surrounding ‘book-farming’ – the practice of farming with knowledge acquired from books – to highlight the wider conflict over agricultural knowledge. The development of agricultural instructional literature gave rise to tensions between an established labour-based and an emerging book-based system of knowledge, which mapped onto social struggles over control of the intellectual powers of production. Hostility to ‘book-farming’ from practical farmers was partly a response to the threat books posed to the customary knowledge of farm workers of various kinds.     

Interpersonal Behavior,Laboratory Learning Environments,and Student Outcomes in Senior Biology Classes

The purpose of this study was to investigate associations between students' perceptions of their biology teachers' interpersonal behavior and their laboratory learning environments and their attitudinal, achievement, and performance outcomes. A sample of 489 students from 28 senior biology classes in eight schools in Tasmania, Australia completed the Questionnaire on Teacher Interaction (QTI) and the Science Laboratory Environment Inventory (SLEI). Responses to two attitude questionnaires, achievement on an external written examination, and performance in laboratory practical tests were used as student outcome measures. Statistical analyses supported the reliability and validity of the QTI and the SLEI when used with senior secondary biology students. We investigated associations between students' perceptions of teacher behavior and their laboratory learning environment with student outcomes, including the unique and common contributions of the QTI and SLEI to variance in student outcomes. Associations with students' perceptions of the learning environment were stronger for the attitudinal outcomes than for the cognitive or practical skills outcomes. Some commonality between the QTI and SLEI scales was found in their contributions to the variance in attitudinal outcomes, but not in their contributions to variance in cognitive and practical skill outcomes. © 1999 John Wiley & Sons, Inc.
