土地革命时期毛泽东信念观探析——重温《井冈山的斗争》与《星星之火， 可以燎原》

1927年大革命失败后,中国革命进入了十年土地革命时期。期间党与红军内部出现了"右"倾悲观思潮,并几度提出"红旗到底打得多久"的疑问。对此,毛泽东在《井冈山的斗争》与《星星之火,可以燎原》等著作中给予了科学回答,形成了毛泽东信念观:坚定信念创建农村革命根据地;坚信红色政权的发生、存在与发展既是可能的,也是必然的;坚信星火必燎原,中国革命高潮必将到来。毛泽东信念观的形成是大革命失败后时局变化的产物,是实行正确政策的必然结果。     

Governing the souls of young women: exploring the perspectives of mothers on parenting in the age of sexualisation

The sexualisation of young women has emerged as a growing concern within contemporary western cultures. This has provoked adult anxieties that young women are growing up too fast by adopting inappropriate sexual practices and subjectivities. Psychological discourses have dominated, which position sexualisation as a corrupting force that infects the ‘true self’ of young women, so they develop in abnormal ways. This in turn allows psychological practices to govern how to parent against sexualisation within families. To explore this further, six mothers each with daughters aged between 8 and 12 took part in one to one semi-structured interviews designed to explore how they conceptualised and parented against the early sexualisation of young women. A Foucauldian inspired discourse analysis was employed, which suggested that the mother's talk was situated within a psychological discourse. This enabled sexualisation to be positioned as a corrupting force that disrupted the natural development of young women through deviant bodily practices (e.g. consuming sexualised goods), which prevented them from becoming their ‘true self’. Through the disciplinary gaze of psychology, class inequalities were reproduced where working class families were construed as ‘chavs’ who were bad parents and a site of contagion for sexualisation.     

Promising more to give less: international disputes between core and periphery around European posted labor, 1955–2018

ABSTRACT

The posting of workers from the European periphery has generated the longest and most tumultuous series of labor disputes in the history of European Integration. On the basis of relevant archives, this article conducts the first historical review of posting rules in the European Union, from the first negotiation in 1955 until the latest directive in 2018. This historical review enables to discard the idea of a neoliberal turn in posting rules from the 1980s onward. It also leads to reject the explanation of disputes by the movement out of the European periphery under posting rules of a Lumpenproletariat insensitive to class struggle. Instead, the article identifies the increasing regulation of the labor market at the expense of posting opportunities since thirty years. It reveals the dominant role played by governments and their invariable support for their workers. It highlights the constant asymmetry of power between core richer countries and the Southern and Eastern periphery of the European Union. Eventually, this article locates the long-term problem in the contradictions between the interests of workers and firms in richer destination countries and the enlargements of the Single Market to poorer countries.     

Single,straight, wants kids: media framing of single,heterosexual fatherhood via assisted reproduction

The new reproductive technologies have made possible various postmodern family forms. I highlight an emerging form that has received little attention: single fathers by choice (SFCs), created by single men using egg donation and surrogacy. I focus on heterosexual SFCs, which have been largely ignored in the scholarly literature even as gay and lesbian parenthood have increasingly become topics of feminist inquiry. This type of fatherhood raises several important questions for gender and family scholars about the ‘traditional’ family, the relationship between masculinity and fatherhood, and men’s own desires for parenthood without a female partner. I analyze US media framing to explore cultural sense-making of SFCs. While media framing cannot tell us about men’s lived experiences as intentional single fathers, it does point to larger discourses that potentially impact these men as they engage in non-normative fathering. I identify three core themes within the media frames: (1) viewing men and women as similar, but ultimately different, (2) addressing the tension between bachelorhood and fatherhood, and (3) representing the gender of paternal desire in multiple, conflicting ways. Overall, I argue that further investigations of SFCs can illuminate issues about men’s desires for children and agency in becoming fathers.     

Confused or competent? How voters use the STV ballot paper

STV is often extolled because it allows voters to express a nuanced choice, but is criticised for being too confusing. In practice the system is little used, but evidence from where it is indicates much depends on how voters choose to use it. STV was used for the first time in Scottish local elections in 2007, providing valuable new evidence on how voters respond to the system. We use survey data to examine the incidence of various indicators of apparent failure by Scottish voters to exploit STV, and compare both the levels and patterns of incidence with equivalent data for Ireland. We find little sign of confusion in either country, but significant evidence of ballot order effects in Scotland.
