Preferences and agreement in legislative parties: testing the causal chain

This research note focuses on two specific dimensions of legislative cohesion: the homogeneity of preferences within a party and party agreement. Although these two dimensions have often been considered as synonyms, it is argued that these two concepts refer to different realities. The authors therefore develop distinct measurements for these two concepts. The authors then examine their statistical relationship, putting to the test the widespread assumption that heterogeneous preferences increase the probability of disagreement. The authors do so by testing the effect of different measures of a member of parliament’s ideological distance to her/his party on her/his self-reported frequency of disagreement with her/his party. It is demonstrated that the causal chain linking both concepts is only verified in the case of a conscious ideological distance. The results have crucial theoretical and methodological implications for future research on party cohesion and party unity.     

On Being a Novice Forensic Evaluator: Reflections from Early Career Forensic Psychologists

Previous research has considered the psychologist’s professional transition from trainee to independent practitioner. However, this work has generally focused on the experiences of psychotherapists or general psychologists. The purpose of the current commentary is to reflect on the experiences of early professional forensic evaluators. This commentary addresses four specific areas including difficulties with adversarial allegiance, perceptions of professional competency, balancing responsibilities associated with “expert” status, and roadblocks to standard test administration and scoring. When applicable, we reference empirical literature and professional ethical guidelines. We also offer suggestions for coping with these experiences. We hope this commentary will normalize these experiences for other early career evaluators as well as aid graduate students’ transition into the independent evaluator role.     

Potency Trends of Δ9‐THC and Other Cannabinoids in Confiscated Cannabis Preparations from 1993 to 2008*

Abstract: The University of Mississippi has a contract with the National Institute on Drug Abuse (NIDA) to carry out a variety of research activities dealing with cannabis, including the Potency Monitoring (PM) program, which provides analytical potency data on cannabis preparations confiscated in the United States. This report provides data on 46,211 samples seized and analyzed by gas chromatography‐flame ionization detection (GC‐FID) during 1993–2008. The data showed an upward trend in the mean Δ⁹‐tetrahydrocannabinol (Δ⁹‐THC) content of all confiscated cannabis preparations, which increased from 3.4% in 1993 to 8.8% in 2008. Hashish potencies did not increase consistently during this period; however, the mean yearly potency varied from 2.5–9.2% (1993–2003) to 12.0–29.3% (2004–2008). Hash oil potencies also varied considerably during this period (16.8 ± 16.3%). The increase in cannabis preparation potency is mainly due to the increase in the potency of nondomestic versus domestic samples.     

Potentials for federation of East African educational programmes

Educational planning, in the modern sense of the term, goes back in Thailand no further than 1962, when the Second Economic and Social Development Plan (1962/66) was launched. The Second Plan included a plan for the educational system as did the Third Plan (1967/71) which is now drawing to a close. These two educational plans were based on a variety of methods, including those of making long‐term forecasts of manpower requirements. Between 1963 and 1967, five different groups prepared manpower forecasts for Thailand, some of which looked no further than 1970, while others projected manpower requirements up to 1968. In this paper we will try to assess the quality of these forecasts and, so far as it is possible, to cmmpare prediction with outcome.

The paper consists of four parts. We begin with a brief review of background data in order to highlight the problems of manpower forecasting in an economy such as that of Thailand. The second section is devoted to a detailed discussion of the first and most ambitious of the five forecasts that have been made in Thailand. This is followed by brief evaluations of the remaining four forecasts. In the fast section, we will consider the influence that these forecasts actually exerted on educational planning in Thailand.     

A Molecular Key for the Identification of Blow Flies in Southeastern Nebraska*

Abstract: Immature blow flies (Calliphoridae) are typically the first colonizers of cadavers. Identification of the early instars using traditional, morphology‐based keys is difficult because of their small size, similarity, and simplicity in external morphology. Information derived from molecular genetic data would augment the accurate identification of immature flies. Nine species of blow flies commonly found in southeastern Nebraska were used to examine the utility of molecular‐based keys. Polymerase chain reaction–restriction fragment length polymorphisms (PCR–RFLP) were investigated with 10 common, inexpensive, restriction enzymes from an amplicon of approximately 1500 bp spanning the mitochondrial cytochrome oxidase I gene. A simple molecular taxonomic key, comprising RFLP from the restriction enzymes HinfI and DraI, enabled the differentiation of all species used. Further development of PCR–RFLP, including more extensive and intensive examination of blow flies, would benefit forensic laboratories in the accurate identification of evidence consisting of immature blow flies.     

Assessing oral skills—time for reflection,time for risk

Abstract

THIS PAPER aims to establish a framework from which we can explain our dissatisfaction with defining what we teach and what and how we assess within legal education. To what extent can we, the professions or the public, have confidence that our assessment processes predict effective professional competence?

We will try to establish this framework by placing the discussion in the context of a workshop of assessment of oral skills run at the 2001 Bar Vocational Course conference. The workshop raised issues which we believe encapsulate the difficulties of measuring performance in such a way that it reliably predicts professional effectiveness. From this we will attempt to highlight the shortcomings of the current teaching, learning and assessment strategies more generally.

We go on to consider the role of student reflection in support of summative assessment: is it a reliable way of helping to plug the competence‐performance gap we have identified? What is its role in summative assessment? What demands does it make on tutor and learner? Since we cannot guarantee to find the best solutions first time, we make a plea for taking the risk of failure as well as success, and trying out ideas.
