Will they stay or will they go? How network properties of WebICs predict dropout rates of valuable Wikipedians

This paper contributes to our understanding of an increasingly prevalent work system, web-based internet communities (WebICs). We are particularly interested in how WebICs are governed given the fact how different they are compared to more classical forms of organization. We study the governance of a WebIC by studying the structure and dynamics of their edit network. Given the fact that the edit network is a relational structure, social network analysis is key to understanding these work systems. We demonstrate that characteristics of the edit network contribute to predicting the dropout hazard of valuable WebIC members. Since WebICs exist only thanks to the activity of their contributors, predicting drop-outs becomes crucial. The results show that reputation and controversy have different effects for different types of Wikipedians; i.e., an actor’s reputation decreases the dropout hazard of active Wikipedians, while participation on controversial pages decreases the dropout hazard of highly active Wikipedians.     

Gender Competition and the Preservation of Community in the Allocation of Administrative Positions in Small Rural Towns in Montana: A Research Note1

Abstract Assignment of administrative positions in a sample of rural towns is demonstrated to be significantly associated with gender. Most civil administrators are women, while most legal and educational administrators are men. The difference indicates structural assignment of positions by gender. Gender and administrative position are demonstrated to have zero-order correlations with perceptions of two important behaviors for community: migration and social problems. The characteristics of the occupation and of the administrators are qualitatively different. The data are compiled from interviews with seventy administrators in five pairs of small towns in Montana, ranging in size from about 200 to approximately 7,000 residents. Each pair contains one agricultural and one scenic recreational town. Comparatively, more women were employed in agricultural towns. Many rural women who become administrators, particularly long-term administrators, may be selected for reasons that help preserve the community by providing opportunities for themselves and their families.     

Youth-Subcultural Studies: Sociological Traditions and Core Concepts

The study of youth subcultures has rich histories in the USA and UK, yet has remained a marginal subfield within cultural sociology. In this article, I begin by reviewing the significance of the Chicago school, strain theory, Birmingham school and post-subcultural studies traditions of youth-cultural and youth-subcultural research. I then conceive of a series of significant analytic concepts that over time have proven themselves to be core components of youth-subcultural studies. These analytic concepts include subcultural style, resistance, subcultural space and media, societal reaction, and identity and authenticity. In each analytic section, I explore major conceptual frames and discuss significant empirical research, on youth subcultures including punk goth, straightedge, riot grrrl skateboarding, rave and club cultures, among others.     

Cellular-Only Substitution in the United States as Lifestyle Adoption: Implications for Telephone Survey Coverage

Historically, the coverage bias from excluding the United Statescell-only population from survey samples has been minimal dueto the relatively small size of this group. However, the unrelentinggrowth of this segment has sparked growing concern that telephonesurveys of the general public in the United States will becomeincreasingly subject to coverage bias. While there is evidencethat demographic weighting can be used to eliminate this bias,the availability of the weights lag behind the rapidly changingcell-only population. To explain the extent of the problem,we propose a reliable model to forecast cell-only populationsize and demographics. This model posits that a stable behavioralprocess, the rate of habit retention, can be estimated fromprior wireless lifestyle adoption in the United States and mayalso describe adoption of the cell-only lifestyle. Using measuresof incentive and habituation, we test this assumption by predictingchanges in the cell-only population size and changes in agedemographics. The accuracy of predictions confirms the two adoptionbehaviors are similar. We then develop forecasts of age demographicsthrough 2009, and show how cell-only lifestyle adoption leadsto potential coverage bias that is better addressed throughthis type of modeling rather than weighting from historicaldata.     

Supplementing a survey with respondent Twitter data to measure e-cigarette information exposure

ABSTRACT

Social media data are increasingly used by researchers to gain insights on individuals’ behaviors and opinions. Platforms like Twitter provide access to individuals’ postings, networks of friends and followers, and the content to which they are exposed. This article presents the methods and results of an exploratory study to supplement survey data with respondents’ Twitter postings, networks of Twitter friends and followers, and information to which they were exposed about e-cigarettes. Twitter use is important to consider in e-cigarette research and other topics influenced by online information sharing and exposure. Further, Twitter metadata provide direct measures of user’s friends and followers as opposed to survey self-reports. We find that Twitter metadata provide similar information to survey questions on Twitter network size without inducing recall error or other measurement issues. Using sentiment coding and machine learning methods, we find Twitter can elucidate on topics difficult to measure via surveys such as online expressed opinions and network composition. We present and discuss models predicting whether respondents’ tweet positively about e-cigarettes using survey and Twitter data, finding the combined data to provide broader measures than either source alone.     

Parental job loss and children's educational attainment in black and white middle-class families

Objectives. We aim to understand why blacks are significantly less likely than whites to perpetuate their middle-class status across generations. To do so, we focus on the potentially different associations between parental job loss and youth's educational attainment in black and white middle-class families.Methods. We use data from the Panel Study of Income Dynamics (PSID), following those children “born” into the survey between 1968 and 1979 and followed through age 21. We conduct multivariate regression analyses to test the association between parental job loss during childhood and youth's educational attainment by age 21.Results. We find that parental job loss is associated with a lesser likelihood of obtaining any postsecondary education for all offspring, but that the association for blacks is almost three times as strong. A substantial share of the differential impact of job loss on black and white middle-class youth is explained by race differences in household wealth, long-run measures of family income, and, especially, parental experience of long-term unemployment.Conclusions. These findings highlight the fragile economic foundation of the black middle class and suggest that intergenerational persistence of class status in this population may be highly dependent on the avoidance of common economic shocks.
