Life Course Analysis—The Courage to Search for Something More

Abstract

In this paper we discuss middle-to-late life issues of the transgender and intersex communities. We demonstrate that these mid-to-late life issues are richly complex, full of courage, coping, risk, and resilience, and are grounded in a socio-ecological landscape of systemic actual and perceived violence and abuse. We examine how this socio-ecological environment affects the “normative” mid-life cycle processes. Practical examples are drawn from the author's field interviews and survey research over the past decade. We close by examining the effects of such a landscape on the middle-age life stage and examine its potential ramifications for old age as well.     

Popular Culture and Workplace Gendering among Varieties of Capitalism: Working Women and their Representation in Japanese Manga

Female empowerment is a prerequisite for a just and sustainable developed society. Being the most developed non‐western country, Japan offers an instructive window onto concerns about gender worldwide. Although overall gender equality is advancing in Japan, difficulties remain, especially in achieving equality in the workplace. We draw on theories of ontological commitment and the psychology of fiction to critically analyse the role of popular culture — in this case manga — in the reproduction of gender inequality in the Japanese workplace. We present examples of four of the most popular mainstream manga aimed at working men and women in Japan and show how women are depicted. We argue that the hyper‐mediated fictional realism of representative tropes generates an ontological commitment to characters and narratives among consumers that reinforces the reproduction of a culturally exceptionalist national political economic space, one of whose essential defining characteristics is a gendered workplace. Our research suggests important implications for researching the relationship between culture, in all its forms, and spatial variation in persistent institutional biases among varieties of capitalism.     

国际贸易中的不平等交换问题研究

个别价值和社会价值的差异、供求失衡、非完全竞争、非对称信息和非市场定价等因素都会产生商品交换中的不平等问题,这些均隶属于不等价交换。生产价格的形成同样会使商品交换中存在不平等交换问题,因为价值(剩余价值)在不同产业或地区之间发生了转移,劳动投入和所得不再完全一致。不过,这种不一致在国内贸易和国际贸易中具有本质的区别。     

Why ‘class’ is too soft a category to capture the explosiveness of social inequality at the beginning of the twenty‐first century

We can distinguish four positions on the continuing, or maybe even increasing, relevance of the category of class at the beginning of the twenty‐first century depending on the extent to which they accord central importance to (1) the reproduction or (2) the transformation of social classes with regard to (3) the distribution of goods without bads or (4) the distribution of goods and bads. One could say that Dean Curran introduces the concept of ‘risk‐class’ to radicalize the class distribution of risk and charts who will able to occupy areas less exposed to risk and who will have little choice but to occupy areas that are exposed to the brunt of the fact of the risk society. As he mentioned it is important to note that this social structuring of the distribution of bads will be affected not only by class, but also by other forms of social structuration of disadvantage, such as gender and race. In order to demonstrate that the distribution of bads is currently exacerbating class differences in life chances, however, Curran concentrates exclusively on phenomena of individual risks. In the process, he overlooks the problem of systemic risks in relation of the state, science, new corporate roles, management the mass media, law, mobile capital and social movements; at the same time, his conceptual frame of reference does not really thematize the interdependence between individual and systemic risks. Those who reduce the problematic of risk to that of the life chances of individuals are unable to grasp the conflicting social and political logics of risk and class conflicts. Or, to put it pointedly: ‘class’ is too soft a category to capture the explosiveness of social inequality in world risk society.     

Gender and Pensions: An Analysis of Factors Affecting Women's Private Pension Scheme Membership in the United Kingdom

There has been considerable debate about the future sustainability of pension provision and, in particular, the precarious position of many female pensioners. The reasons for women's lower participation rates in private pensions than men's require greater investigation. Using the General Lifestyle Survey (GLF) 2008, this article examines the impact of various characteristics on the likelihood of contributing to a private pension, such as educational attainments, income, occupational group, full-time/part-time status, and whether an individual has any dependent children. It shows that these characteristics play an important role in access to private pensions. Finally, it suggests that strategies to alleviate disadvantages must take into account the complex circumstances that individuals experience throughout the life course, which result in gendered pension provision.     

Concern about the rise of lazy welfare queens? An empirical explanation of the underdevelopment of the redistributive welfare system in South Korea

This study investigates why South Korea has maintained a minimalist welfare state with little redistribution of income. Inspired by the behavioral/attitudinal approach of Alesina and his colleagues, this study focuses on the perception that people who do not work become lazy. This belief is related to the anti-welfare sentiment that non-working benefits encourage laziness. This study shows that perceptions of work and laziness are associated with preferences for redistribution, not only among South Koreans, but also among individuals in Organization for Economic Cooperation and Development (OECD) member countries. Further, such perceptions are also associated with the redistribution policies chosen in a country. This study provides evidence that societal beliefs about work and laziness, along with several other political and economic factors, such as pre-tax income inequality, political institutions, and union density, may explain the small-scale redistribution in South Korea.     

In response to Gans: the culture–structure binary

Gans (2012 Gans, H. 2012. Against culture versus structure. Identities: Global Studies in Culture and Power, 19(2): 125–134. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]; Against culture versus structure. Identities: Global Studies in Culture and Power, 19 (2), 125–134) makes four assertions in his claim that ‘Contemporary sociology is saddled with a culture–structure binary but the fault for its existence lies mostly with cultural sociology … and the culture–structure binary should be abandoned’. I argue that (1) defining culture, while problematic, is insufficient reason for abandoning the concept. (2) Marx, among others, proffered a dialectical view of culture that is not structural only or interpretive only. (3) Gans ignores the social and political impact of cultural studies, specifically the Birmingham Centre for Contemporary Cultural Studies. And (4) culturally oriented research has been used extensively to shape and analyse the varying approaches by public policy-makers to critical social issues.     

Labor after Neoliberalism: The Birth of the Insecure Class in South Korea

Abstract

This article examines the rise and fall of organized labor in post-democratization, neoliberal Korea and traces the process through which a new labor underclass has been created since the late 1990s. Under the sweeping implementation of neoliberal policies, Korean labor has become increasingly fragmented, stratified, and marginalized both in the market and political arena. In this polarizing process, an ‘insecure class’ was born, consisting of irregular workers and the low-income self-employed. These working people are characterized by precarious labor conditions, bare social protection coverage, and frail organizational–political representation. This study explicates such a drastic restructuration of the Korean working people from the interaction of chaebol-centered economic structure, labor unions' organizational narrowness, and unrepresentative political parties devoid of programmatic competition. The examination of the insecure class in Korea casts light on the significance of class issues in neoliberal political economy and the analytical importance of rethinking social class in contemporary capitalist societies.
