Introduction: German Party Membership in the 21st Century

The party membership decline experienced in Germany in the last decades raises a number of theoretical, empirical, and normative questions, a selection of which is addressed in this special issue of German Politics. In this introduction, we summarise some of the central arguments and findings presented. Although the individual articles take various perspectives and present specific insights, as a whole they allow for drawing some consequences: Firstly, party membership decline seems to be irreversible, secondly, it does neither imply an inadequate organisational linkage between society and state institutions nor, thirdly, a threat to democracy.     

Substantiated Childhood Maltreatment and Intimate Partner Violence Victimization in Young Adulthood: A Birth Cohort Study

Little is known about the associations between various types of childhood maltreatment and multiple forms of intimate partner violence victimization in early adulthood. This study examines the extent to which childhood experiences of maltreatment increase the risk for intimate partner violence victimization in early adulthood. Data for the present study are from 3322 young adults (55?% female) of the Mater Hospital-University of Queensland Study of Pregnancy with the mean age of 20.6 years. The Mater Hospital-University of Queensland Study of Pregnancy is a prospective Australian pre-birth cohort study of mothers consecutively recruited during their first antenatal clinic visit at Brisbane’s Mater Hospital from 1981 through to 1983. Participants completed the Composite Abuse Scale at 21-year follow-up and linked this dataset to agency recorded substantiated cases of childhood maltreatment. In adjusted models, the odds of reporting emotional intimate partner violence victimization were 1.84, 2.64 and 3.19 times higher in physically abused, neglected and emotionally abused children, respectively. Similarly, the odds of physical intimate partner violence victimization were 1.76, 2.31, 2.74 and 2.76 times higher in those children who had experienced physical abuse, sexual abuse, neglect and emotional abuse, respectively. Harassment was 1.63 times higher in emotionally abused children. The odds of severe combined abuse were 3.97 and 4.62 times greater for emotionally abused and neglected children, respectively. The strongest associations involved reports of child emotional abuse and neglect and multiple forms of intimate partner violence victimization in young adulthood. Childhood maltreatment is a chronic adversity that is associated with specific and multiple forms of intimate partner violence victimization in adulthood.     

Japan’s uncertain security environment and changes in its legislative‒executive relations

Abstract

Focusing on Japan, this paper explores whether powers and competences in the political system are likely to be recalibrated in favour of the executive when the environment is perceived as increasingly threatening. It shows that the executive has been significantly strengthened during the past two decades of political reforms, though a closer look reveals that only the most recent efforts are motivated by security concerns. Case studies on military deployments and arms exports do not expose any clear trend towards curbing parliament’s formal control powers, but they indicate two related mechanisms that affect executive?legislative relations. Firstly, the executive has sought to ensure faster decision-making in security policy, which may limit the Diet’s ability to scrutinise policies in depth. Secondly, the level of contestation over security policy issues has been decreasing, especially given the securitisation of North Korea and China. This provides the executive with more leeway in devising policies.     

International Feminism and Empire‐Building between the Wars: the case of Viola Smith

This article examines US Trade Commissioner Viola Smith’s role in the furtherance of the American empire between World Wars I and II. As a Foreign Service Officer in Shanghai, China on behalf of the Department of Commerce and through her activism as an international feminist in the Pacific region, Smith perpetuated the imperialist project. As Trade Commissioner, she implemented trade policy in lucrative China that helped to economically enrich the USA. Likewise, as an international feminist, Smith injected Western superiority to the international feminist sphere through her work for peace and women’s rights in the Pacific.     

The Individual-Level Determinants of Exiting German Parties

With respect to explaining declining party membership, the question who leaves political parties and why has so far been neglected. This article aims to fill this gap by applying Hirschman’s theory of “Exit, Voice, and Loyalty” to both current and former party members, and at combining it with the resource model of political participation. We find that neither individual resources nor reasons for discontent are sufficient to explain the different reactions to discontent, but that the exit-voice-loyalty model has a certain explanatory power.     

On the applicability of secondary dentin formation to radiological age estimation in young adults

The literature provides linear regression formulas for dental age estimation that is based on radiological two-dimensional measurements of the pulp size. The aim of the present study was to explore whether the previously presented regression formulas could lead to statistically sound results and to appropriate repeatability when applied to young individuals. Orthopantomograms (OPGs) of 44 Austrian individuals, aged between 13 and 24 years, were selected at random. In accordance with the reported method, six teeth on each OPG were chosen to carry out the measurements. Statistical analysis was performed in order to assess the difference between the estimated and the true chronological age. The regression formulas reported by Kvaal et al. (1995) led to a consistent underestimation; the regression formulas reported by Paewinsky et al. (2005) resulted in a constant overestimation of age. The statistical analysis of intraobserver and interobserver variation revealed a variation width below 2%, respectively.     

The (In)stability of Voters’ Perceptions of Competence and Associative Issue Ownership: The Role of Media Campaign Coverage

Recent work has suggested that issue ownership has a competence and an associative dimension and that both dimensions are less stable than originally assumed. This study is the first attempt to directly compare the stability and change of voters’ perceptions on both dimensions. Using data from the 2015 Swiss Election Study, linking data from a combined panel/rolling cross-section survey with an extensive media analysis, this study finds that voters are more likely to maintain their issue ownership perceptions if the party they identify as the issue owner before the campaign receives a higher share of media campaign coverage. This stabilizing effect is conditional on the importance of the issue for the voter, and it is stronger for voters’ competence evaluations than for their party-issue associations, which proved to be more stable. Thus, the results confirm the literature’s previously untested assumption that voters’ associative ownership perceptions are more stable than their competence ownership evaluations.
