Estimation of Models with Beta-Distributed Dependent Variables: A Replication and Extension of Paolino's Study

This note replicates and extends Paolino's discussion (2001,Political Analysis 9:325–346) on the estimation of modelswith beta-distributed dependent variables in two ways. First,it introduces an easy-to-use program for estimating the modelusing Stata. Second, it presents a Bayesian estimator for betavariables based on Paolino's model. Results are compared tothose in the original article.     

Amsterdam as a Global City: Restructuring,Identity Rearticulation,and Resistance in the Service Sector

This article explores the interconnections between political‐economic transformations of Amsterdam into a second‐tier global city and the rearticulation of (gender) identities and resistance practices in the service sector. The research focuses on both the high and low ends of the service sector, i.e., banking and cleaning. Given different positionalities of employees in respective sectors, the article shows that their responses to changes in their work environment take on different modalities. Women managers in the banking sector resort to a strategy of “hiding” their gender identity and individualized responses, while Moroccan (male) cleaners tend to underscore the masculine nature of their work and are joining labor unions in greater numbers than before.     

Short-term forces and partisan change in Canada: 1974–1980

The theoretical attractiveness of party identification derives in large measure from its presumed stability at the level of the individual voter. Recent studies conducted in Great Britain and the United States suggest, however, that partisan attachments are less stable than originally believed, and respond to the impact of shortterm forces. This paper uses newly available, national panel surveys to consider the Canadian case. Between 1974 and 1980 party identification in this country is characterized by aggregate stability and individual change. The latter is not confined to particular groups of voters and is not strongly associated with time-related reinforcement effects, but rather reflects variations in party leader and party/issue preferences. Further, interaction effects suggest that extent of political interest and patterns of partisanship across levels of the federal system condition processes of partisan change.     

Anti-sexist men: A case of cloak-and-dagger chauvinism

The paper looks at the sexual behaviour of anti-sexist men as this is presented in writing, in discussion, and in personal experience of them. It shows that changes in the sexual behaviour of anti-sexist men have been those that serve their own interests. Some anti-sexist male writing about sex describes how some of them cannot get an erection without objectifying the women they're in bed with; and they don't tell these women about the misogynistic fantasies they have in order to objectify them. Drawing on this, on discussions with anti-sexist men and on personal experience, it seems that ‘impotence’ is a common reaction to stroppy feminists and sexually active women. The paper concludes that male anti-sexism is more a ‘cloak-and-dagger form of chauvinism’ than a genuine attempt to lose their power over women.     

Evaluation of methyl tert-butyl ether (MTBE) as an interference on commercial breath-alcohol analyzers.

Anecdotal reports suggest that high environmental or occupational exposures to the fuel oxygenate methyl tert-butyl ether (MTBE) may result in breath concentrations that are sufficiently elevated to cause a false positive on commercial breath-alcohol analyzers. We evaluated this possibility in vitro by establishing a response curve for simulated breath containing MTBE in ethanol. Two types of breath-alcohol analyzers were evaluated. One analyzer's principle of operation involves in situ wet chemistry (oxidation of ethanol in a potassium dichromate solution) and absorption of visible light. The second instrument uses a combination of infrared absorption and an electrochemical sensor. Both types of instruments are currently used, although the former method represents older technology while the latter method represents newer technology.The percent blood alcohol response curve was evaluated over a breath concentration range thought to be relevant to high-level environmental or occupational exposure (0-361 microg/l). Results indicate that MTBE positively biases the response of the older technology Breathalyzer when evaluated as a single constituent or in combination with ethanol. We conclude that a false positive is possible on this instrument if the MTBE exposure is very high, recent with respect to testing, and occurs in combination with ethanol consumption. The interference can be identified on the older technology instrument by a time dependent post-reading increase in the instrument response that does not occur for ethanol alone. In contrast, the newer technology instrument using infrared and electrochemical detectors did not respond to MTBE at lower levels (0-36 microg/l), and at higher levels (>72 microg/l) the instrument indicated an "interference" or "error". For this instrument, a false positive does not occur even at high MTBE levels in the presence of ethanol.     

Acute Respiratory Obstruction due to Accidental Inhalation of Perlite: A Novel Mechanism for Upper Airway Occlusion with Cast Formation

A 56-year-old man died following a fall resulting in complete submersion into a deep pit containing insulation material, expanded perlite. The most striking finding at autopsy was of impacted, moist pale yellow perlite that extended from the epiglottis into the main bronchi resulting in complete obstruction of the larger and smaller airways with cast formation. Perlite inhalation differs from inhalation of inert materials such as sand and wheat due to its hygroscopic properties and ability to expand forming an occlusive cast. Subsequent analyses of perlite from the worksite and within the airways indicated that hydration of perlite and adsorption of organic molecules into the perlite glass flakes had formed an interlocking, three-dimensional structure that was likely responsible for triggering a coagulation–flocculation process causing strong cohesion between the aggregates of glass flakes. This unique mechanism was likely responsible for the formation of the plug of perlite that obstructed the upper airway.     

Gender and Perceived Control in the Russian Federation

The consequences of the socioeconomic transition for male physical health in Russia are widely documented, but much less research examines psychological well-being and mental outlook, or how these outcomes differ for men and women in Russia. Exploring gender differences in personal control, an important aspect of psychological well-being, we find that, controlling for social and economic factors, Russian women report lower levels of control than men. Gender differences in the social determinants of perceived control highlight the importance of gender roles for understanding psychological stress and inform how social expectations differentially influence men's and women's paths to well-being in Russia.
