Changing American home life: trends in domestic leisure and storage among middle-class families

This study of middle-class American families draws on ethnography and urban economic history, focusing on patterns of leisure time and household consumption and clutter. We trace how residential life evolved historically from cramped urban quarters into contemporary middle-class residences and examine how busy working families use house spaces. Our ethnographic sample consists of 24 Los Angeles families in which both parents work full time, have young children, and own their homes. Formal datasets include systematically timed family uses of home spaces, a large digital archive of photographs, and family-narrated video home tours. This analysis highlights a salient home-storage crisis, a marked shift in the uses of yards and garages, and the dissolution of outdoor leisure for busy working parents. The UCLA Center on Everyday Lives of Families (CELF) is generously supported by the Alfred P. Sloan Foundation program on the Workplace, Workforce, and Working Families. Anthony Graesch assisted with the tables. Additional information about CELF can be found at www.celf.ucla.edu.

Locative Mobile Social Networks: Mapping Communication and Location in Urban Spaces

Abstract

This study conceptualizes the new spatial logic created by the social use of location aware mobile technologies, analyzing how mobile communities are formed by the mapping of social networks in urban spaces. It explores two main areas with the goal of understanding how locative mobile social networks (LMSNs) challenge the traditional logic of networks. First, it conceptualizes LMSNs by comparing them to (1) traditional transportation and communication networks, and (2) mobile social networks (MSNs). Second, the paper discusses potential social implications of LMSNs, such as privacy, surveillance, and social exclusion.     

大江健三郎作品中的狂欢化精神

获得诺贝尔文学奖的日本作家大江健三郎,始终从边缘的角度出发,关注边缘人物命运及边缘文化,以狂欢的写作手法,搭建了一个狂欢舞台,展示了边缘人物对主流政治和文化的对抗。分析大江文学作品中的人物狂欢、空间狂欢、性的狂欢等,可以揭示大江文学作品中狂欢化精神的实质内涵:自由与平等、颠覆与再生。     

Testing for additivity and joint effects in multivariate nonparametric regression using Fourier and wavelet methods

We consider the problem of testing for additivity and joint effects in multivariate nonparametric regression when the data are modelled as observations of an unknown response function observed on a d-dimensional (d 2) lattice and contaminated with additive Gaussian noise. We propose tests for additivity and joint effects, appropriate for both homogeneous and inhomogeneous response functions, using the particular structure of the data expanded in tensor product Fourier or wavelet bases studied recently by Amato and Antoniadis (2001) and Amato, Antoniadis and De Feis (2002). The corresponding tests are constructed by applying the adaptive Neyman truncation and wavelet thresholding procedures of Fan (1996), for testing a high-dimensional Gaussian mean, to the resulting empirical Fourier and wavelet coefficients. As a consequence, asymptotic normality of the proposed test statistics under the null hypothesis and lower bounds of the corresponding powers under a specific alternative are derived. We use several simulated examples to illustrate the performance of the proposed tests, and we make comparisons with other tests available in the literature.     

Fauconnier的空间映射论及其在话语分析中的应用

认知语言学为研究和解释语言现象提供了新的研究方法,属于广义认知科学的一个分支。文章在以Lakoff为代表的认知语义学的基础上,运用Fauconn ier模式理论中的心理空间理论和空间映射论,采用认知科学的理念分析解释了隐喻转喻映射和ICM的图式映射等问题,并指出作为一种重要的认知模式,其空间理论可以帮助解读许多日常言语交际中“非常规”的语言事实,为许多语言现象的研究提供了一种新的认知模式。     

The Sidewalk as a Contested Space: Women’s Negotiation of Socio-Spatial Processes of Exclusion in Public Urban Space in Saudi Arabia; The Case of Al Tahlia Street

Riyadh is one of the most gender-segregated cities in the world. However, as gender segregation is less enforced on sidewalks, it provides an optimal case study for a space where women and men may be co-present. Thus, this paper aims to increase the understanding of the relationship between sociocultural norms and spatial programming regarding spatio-temporal inclusion or exclusion in public urban spaces. The results show that women’s use and access to sidewalks are influenced by gender norms, religious values, gendered regulations, and generic spatial programming. For instance, regulations limit the use of outdoor seating to men only, thus sidewalks adjacent to, e.g., cafes function as mono-gender spaces dominated by men. However, young women negotiate spatially bounded gender norms through their presence, behaviour, and dress. Although sidewalks are conceived as men’s space, women account for nearly half of the users, but their use often goes unnoticed as women self-regulate their spatio-temporal and visible presence. The study presents six types of women’s spatio-temporal behaviours with varying degrees of visible and invisible users. Ultimately, this paper argues that planning for inclusive sidewalks cannot be addressed solely through the ‘universal’ characterization of space; it should also be supplemented by context-specific knowledge regarding the socio-spatial needs.     

Modelling free social spaces and the diffusion of social mobilization

Free social spaces have long been emphasized in the social movement literature. Under names such as safe spaces, social havens, and counterpublics, they have been characterized as protective shelters against prevailing hegemonic ideologies and as hubs for the diffusion of ideas and ideologies. However, the vast literature on these spaces has predominantly focused on internal dynamics and processes, thus neglecting how they relate to the diffusion of collective mobilization. Inspired by formal modeling in collective action research, we develop a network model to investigate how the structural properties of free social spaces impact the diffusion of collective mobilization. Our results show that the assumption of clustering is enough for structural effects to emerge, and that clustering furthermore interacts synergistically with political deviance. This indicates that it is not only internal dynamics that play a role in the relevance of free social spaces for collective action. Our approach also illustrates how formal modeling can deepen our understanding of diffusion processes in collective mobilizations through analysis of emergent structural effects.     

‘How to be a rural man’: Young men's performances and negotiations of rural masculinities

This paper is concerned with young rural men and how they ‘do’ identity politics living in a rural area of Norway. Focusing on how masculinity and rurality are constructed and interrelated in young men's narratives of living in a remote community, it is identified that young rural men reproduce, negotiate and transform local discourses of rural masculinity. First, the article shows that young men living in rural areas believe it is important to express rural masculinity through hunting and outdoor life as well as by exhibiting skills as handymen. Second, it reveals that it is important for young rural men to communicate a particular stance in the ongoing and controversial Norwegian debate over snowmobiles and carnivores, as these topics are related to rural men's sense of loyalty to place. Third, the article shows how rural men negotiate ‘the tough man’ images related to hunting, motors and handyman skills by constructing new and alternative masculinities. The analysis reveals that young rural men enact alternative masculinities, expressed in relation to new working life opportunities in the service sector, through emotional openness and caring, and in relation to traditional ‘masculine spaces’ such as hunting and snowmobiling. It is concluded that, little by little, rural communities are opening up for more flexible masculinities.
