The Many-Headed Hydra: Sailors, Slaves, and the Atlantic Working Class in the Eighteenth Century

Abstract This article uses the myth of the many-headed Hydra, commonly employed by members of various ruling classes around the Atlantic to describe the class struggles that surrounded them, to illuminate the history of the working class in the eighteenth century. It concentrates on two groups of workers, wage laborers (especially sailors) and slaves, two zones of the Atlantic, Europe and North America, and four moments in the history of the Atlantic working class: 1747, when, in the Knowles Riot in Boston, sailors and slaves fought the King's press gangs and in so doing created one of the central ideas of the 'Age of Revolution' 1768, when, in the London port strike, sailors, Irish coal heavers, and others pioneered one of the central ideas and activities of the modern working-class movement, the strike; 1776, when, in the American Revolution, sailors and slaves helped to instigate and win the world's first colonial war for liberation; and 1780, when, in the Gordon Riots, the polyglot working class of London liberated the prisons amid the greatest municipal insurrection of the eighteenth century. It argues that fixed, static notions of race, ethnicity, and nationality among historians have obscured a vital world of cooperation and accomplishment within a multi-racial, multi-ethnic, international working class.

Globalization of Culture and the Arts

This article examines the state of the field in the sociological literature on the globalization of culture and focuses on key empirical works in the globalization of the arts. The first part of the article presents the main trends in theorizing about the globalization of culture in its broadest terms, that is, the large-scale changes in worldviews that both facilitate and are made possible by globalization such as modernization, universalism, consumerism, and McDonaldization. The second part of the article examines empirical work on television, music, and the performing arts in light of theorizing about globalization and commodification, audience reception, localization and glocalization, the role of the state, imperialism, global cultural fields, and global norms. In terms of theory, the article explores the tension between globalization's homogenizing and diversifying tendencies. The review of the empirical literature includes research conducted in Cuba, Israel, Italy, Japan, Russia, Singapore, the USA, and Uzbekistan.     

中国青年文化景观的形成轨迹与引导理路

中华人民共和国成立以来,特别是改革开放以来,青年文化发展出现服从与反思、解放与迷茫、理性与矛盾勾勒的变迁图景,也反映出新时代青年文化的发展趋向。新时代的青年文化景观既具有青年文化的预见性与超越性、进取性和建构性、理想性和生活性等共性特征,又突出表现为雅俗共赏、进退有度、家国兼顾的时代特性。新时代,应注重从个人追求与社会理想的统一、独立思想与过硬本领的统一、青春热情与社会担当的统一几方面入手,突出政治引领、思想引领、责任引领在青年文化引导上的关键作用,推动青年文化持续向前发展。     

后现代思潮对我国青少年的影响与对策

出于反思"现代性"而出现的后现代主义,目前已经发展成"带有西方色彩"的全球性社会思潮。它反对理性主义、整体主义、中心主义,主张多元价值取向,注重人文关怀,具有否定的全面性与不彻底性、价值取向的无中心性、传播形式的灵活性与多样性、行为表现的随意性等特点。后现代主义在一定程度上有助于培养我国青少年的批判性思维,有助于青少年的天性成长,但也往往易于模糊青少年的是非判断标准,侵蚀青少年积极有为的责任担当,诱使青少年养成享乐主义的生活习惯。为此,需要从强化社会主义核心价值观的引领作用、加强对西方后现代思潮的理论研究、加强人文精神和心理健康方面的教育、引领网络与大众传播方向等方面做文章。     

房子与骰子:财富交换之链的个案研究

在礼物—交换理论中,互惠是一个支配性的概念,费孝通提出的反馈模式也深受影响。本文基于一个浙江村落的民族志资料,考察了家户经济中财富的流通模式,并反思了互惠概念在解释中国社会方面的有效性及其限度。在村落和家户中,互惠行为的确占有相当重要的地位,如工作、交易、人情来往、赌博等。与此同时,在家户经济中,还有一些不可转让之物,如土地、坟墓、房屋等财产,这些传家宝只能向下逐代传递,而不能进入流通的领域。在这一意义上,在研究汉人社会时,运用费孝通的反馈模式,也应考虑他关于根的论述。

Social change and the family: Comparative perspectives from the west,China, and South Asia

This paper examines the influence of social and economic change on family structure and relationships: How do such economic and social transformations as industrialization, urbanization, demographic change, the expansion of education, and the long-term growth of income influence the family? We take a comparative and historical approach, reviewing the experiences of three major sociocultural regions: the West, China, and South Asia. Many of the changes that have occurred in family life have been remarkably similar in the three settings—the separation of the workplace from the home, increased training of children in nonfamilial institutions, the development of living arrangements outside the family household, increased access of children to financial and other productive resources, and increased participation by children in the selection of a mate. While the similarities of family change in diverse cultural settings are striking, specific aspects of change have varied across settings because of significant pre-existing differences in family structure, residential patterns of marriage, autonomy of children, and the role of marriage within kinship systems.     

Capitalism,Protestantism and the Private Family: Comparisons among Early Modern England,France, and the American Colonies*

The study of western family change lies disintegrated, divided into two largely independent intellectual communities–family history and theoretical family sociology. An integration of the two fields is proposed. The results of family historical research from three national cases, England, France, and the North American Colonies, are used to evaluate critically the family theories of Parsons, Seccombe, Zaretsky, and Horkheimer. The pattern of family organization regarded as modern, including the differentiation of the family from other social institutions, the emergence of companionate marriage, and the consolidation of authority over the family in the role of the father, characterize the family systems of England and the Colonies better than that of France. A theory of modern family organization is proposed that identifies the emergence of a culturally dominant middle class and the institutionalization of Protestantism as facilitating conditions for the development of this private family system.
