Social Movements and Socio-Political Change in Africa: The Ufungamano Initiative and Kenyan Constitutional Reform Struggles (1999–2005)

This article analyses the Ufungamano Initiative, a broad-based movement involved in constitutional reform struggles in Kenya. By analysing the rise, operations, achievements, and challenges of the Initiative, I argue that contemporary constitutional reform struggles in Kenya were societal responses to an avaricious political and economic class. It is further argued that the movement resulted from a fragmented elite consensus that widened political opportunities for contentious politics and therefore forced concessions for popular engagement in re-defining the relationship between the people and the political class. Ultimately, the Ufungamano Initiative’s power eroded as a result of multiple competing parochial interests in the movement.     

Gender identity and lexical variation in social media

We present a study of the relationship between gender, linguistic style, and social networks, using a novel corpus of 14,000 Twitter users. Prior quantitative work on gender often treats this social variable as a female/male binary; we argue for a more nuanced approach. By clustering Twitter users, we find a natural decomposition of the dataset into various styles and topical interests. Many clusters have strong gender orientations, but their use of linguistic resources sometimes directly conflicts with the population‐level language statistics. We view these clusters as a more accurate reflection of the multifaceted nature of gendered language styles. Previous corpus‐based work has also had little to say about individuals whose linguistic styles defy population‐level gender patterns. To identify such individuals, we train a statistical classifier, and measure the classifier confidence for each individual in the dataset. Examining individuals whose language does not match the classifier's model for their gender, we find that they have social networks that include significantly fewer same‐gender social connections and that, in general, social network homophily is correlated with the use of same‐gender language markers. Pairing computational methods and social theory thus offers a new perspective on how gender emerges as individuals position themselves relative to audiences, topics, and mainstream gender norms.     

Estimating heritability for cause specific mortality based on twin studies

There has been considerable interest in studying the magnitude and type of inheritance of specific diseases. This is typically derived from family or twin studies, where the basic idea is to compare the correlation for different pairs that share different amount of genes. We here consider data from the Danish twin registry and discuss how to define heritability for cancer occurrence. The key point is that this should be done taking censoring as well as competing risks due to e.g.  death into account. We describe the dependence between twins on the probability scale and show that various models can be used to achieve sensible estimates of the dependence within monozygotic and dizygotic twin pairs that may vary over time. These dependence measures can subsequently be decomposed into a genetic and environmental component using random effects models. We here present several novel models that in essence describe the association in terms of the concordance probability, i.e., the probability that both twins experience the event, in the competing risks setting. We also discuss how to deal with the left truncation present in the Nordic twin registries, due to sampling only of twin pairs where both twins are alive at the initiation of the registries.     

Determinants of sexual arousal and accuracy of its self-estimation in sexually functional males

Men with and without sexual dysfunction present with varying patterns of agreement between subjective estimates of sexual arousal and more objective psychophysiological measures of the same construct. This relative accuracy seems to be associated with sexual function, with men who have sexual dysfunction presenting less accurate estimations (mostly reporting below measured arousal levels). The purpose of this study is to clarify the processes underlying sexual arousal and the accuracy of its self-estimation. We looked at potential predictors of sexual arousal (subjective and physiological) and accuracy in estimating objective sexual arousal in a sample of 60 sexually functional males. Predictors included pre-existing sexual attitudes (erotophobia), both trait and state positive and negative affect, self-focused attention, and interoceptive awareness. Results indicate that this sexually functional sample generally reported below their own erection level. Interestingly, trait negative affect was associated with somewhat lower levels of subjective arousal and higher levels of physiological arousal. On the other hand, state positive affect facilitated both subjective and objective arousal and increased somewhat the accuracy of estimates of erectile responding. Pre-existing sexual attitudes as well as variations in self-focused attention and interoceptive awareness evidenced little effect on sexual arousal or the accuracy of its estimation.     

Job continuity among new mothers

In the early 1990s, both state and federal governments enacted maternity-leave legislation. The key provision of that legislation is that after a leave of a limited duration, the recent mother is guaranteed the right to return to her preleave employer at the same or equivalent position. Using data from the National Longitudinal Survey of Youth, we correlate work status after childbirth with work status before pregnancy to estimate the prevalence, before the legislation, of returns to the preleave employer. Among women working full-time before the pregnancy, return to the prepregnancy employer was quite common. Sixty percent of women who worked full-time before the birth of a child continued to work for the same employer after the child was born. Furthermore, the labor market behavior of most of the remaining 40% suggests that maternity-leave legislation is unlikely to have a major effect on job continuity. Compared with all demographically similar women, however, new mothers have an excess probability of leaving their jobs.     

Ideas, private institutions and American welfare state 'exceptionalism': the case of health and old-age insurance, 1915–1965

Traditional theories of welfare state development divide into two camps: societal accounts and institutional accounts. The aim of the present article is to amend and enrich the institutional approach to US social policy by reconsidering key aspects of the genesis of the American welfare state: 1) showing that concepts such as 'policy feedback' and 'path dependence' need to be extended to encompass the effect of private social policies; and 2) taking policy paradigms and agenda setting more seriously than is the norm in institutional scholarship. The empirical analysis is divided into two parts. The first part explores the activities of the American Association for Labor Legislation (AALL) in the decade beginning in 1910 and the genesis of Social Security in the 1930s, while the second part examines the effect of the private benefit developments on policy choices between 1935 and 1965.
