Trading twitter: Amateur recorders and economies of scientific exchange at the Cornell Library of Natural Sounds.

Scientists have long engaged in collaborations with field collectors, but how are such collaborations established and maintained? This article examines structures of collaborative data collection between professional scientists and various field recorders around the Cornell Library of Natural Sounds. The Library collects animal sound recordings for use in education, preservation, and entertainment, but primarily in the scientific field of bio-acoustics. Since 1945, the Library has enlisted academic researchers, commercial recorders and broadcasters (such as the British Broadcasting Corporation), and amateur sound hunters in its expansion. I argue that the Cornell Library of Natural Sounds managed to craft and sustain a crucial network of contributors through creative and strategic brokering with its collection of recordings/data. Drawing on notions from exchange theory, I show that sound recordings were valued not just as scientific data, but also as copyrighted commodities that could be bought, sold, traded, and converted in a range of economic, social, and symbolic capitals within collaborators' respective social fields. Thus, aligning collaborators' interests, these exchange relations enabled the Cornell Library of Natural Sounds to negotiate amateur recorders' reliability, willingness to share work, and commitment to scientific standards, as well as the bonds that solidified their collaboration with the Cornell Library of Natural Sounds. Attending to the micro-economics of data exchange, this article thus brings into perspective the multi-dimensional processes through which data-flows are managed.

Blood groups and human groups: collecting and calibrating genetic data after World War Two.

Arthur Mourant's The Distribution of the Human Blood Groups (1954) was an "indispensable" reference book on the "anthropology of blood groups" containing a vast collection of human genetic data. It was based on the results of blood-grouping tests carried out on half-a-million people and drew together studies on diverse populations around the world: from rural communities, to religious exiles, to volunteer transfusion donors. This paper pieces together sequential stages in the production of a small fraction of the blood-group data in Mourant's book, to examine how he and his colleagues made genetic data from people. Using sources from several collecting projects, I follow how blood was encountered, how it was inscribed, and how it was turned into a laboratory resource. I trace Mourant's analytical and representational strategies to make blood groups both credibly 'genetic' and understood as relevant to human ancestry, race and history. In this story, 'populations' were not simply given, but were produced through public health, colonial and post-colonial institutions, and by the labour and expertise of subjects, assistants and mediators. Genetic data were not self-evidently 'biological', but were shaped by existing historical and geographical identities, by political relationships, and by notions of kinship and belonging.

Chromosome surveys of human populations: between epidemiology and anthropology.

It is commonly held that after 1945 human genetics turned medical and focussed on the individual rather than on the study of human populations that had become discredited. However, a closer look at the research practices at the time quickly reveals that human population studies, using old and new tools, prospered in this period. The essay focuses on the rise of chromosome analysis as a new tool for the study of human populations. It reviews a broad array of population studies ranging from newborn screening programmes to studies of isolated or 'primitive' people. Throughout, it highlights the continuing role of concerns and opportunities raised by the propagation of atomic energy for civilian and military uses, the collection of large data bases and computers, and the role of international organisations like the World Health Organisation and the International Biological Programme in shaping research agendas and carving out a space for human heredity in the postwar era.

The influence of world societal forces on social tolerance. A time comparative study of prejudices in 32 countries.

Societal variation in xenophobia, homophobia, and other prejudices is frequently explained by the economic background and political history of different countries. This article expands these explanations by considering the influence of world societal factors on individual attitudes. The empirical analysis is based on survey data collected within the World Value Survey and European Values Study framework between 1989 and 2010. Data are combined to a three-wave cross-sectional design including about 130,000 respondents from 32 countries. Results show that xenophobia and homophobia are influenced by the national political history, societal affluence, and the presence of international organizations. Global forces, however, are of particular importance for homophobia.

Intergenerational transmission of reproductive behavior during the demographic transition.

New evidence from the Utah Population Database (UPDP) reveals that at the onset of the fertility transition, reproductive behavior was transmitted across generations - between women and their mothers, as well as between women and their husbands' family of origin. Age at marriage, age at last birth, and the number of children ever born are positively correlated in the data, most strongly among first-born daughters and among cohorts born later in the fertility transition. Intergenerational ties, including the presence of mothers and mothers-in-law, influenced the hazard of progressing to a next birth. The findings suggest that the practice of parity-dependent marital fertility control and inter-birth spacing behavior derived, in part, from the previous generation and that the potential for mothers and mothers-in-law to help in the rearing of children encouraged higher marital fertility.

The reverse environmental gender gap in China: evidence from "The China Survey".

Objectives This article explores gender differences in attitudes about the seriousness of the environment as a problem in China using the "2008 China Survey." Methods We use generalized ordered logit models to analyze survey respondents' environmental attitudes. Results Our results indicate that there is indeed a "gender gap" in environmental attitudes in China, but the pattern is reversed from what has been generally found in previous work conducted in the United States and Europe. Chinese men, not women, show a greater concern about environmental problems and the seriousness of the environmental degradation in China. Further, we find that this gender gap is based largely in the substantial economic and educational differences between men and women in contemporary China. Conclusions This study emphasizes the mediating influence of socioeconomic variables in explaining gender attitudes toward the environment in China. Our findings suggest that in different contexts, women may be faced with difficult decisions between immediate economic necessities and long-term environmental concerns. The observed environmental gender gap in China will likely persist unless further economic development results in improved access to education and economic conditions for Chinese women.

Has anyone seen it? Health care in Croatian elections.

Over the past decade, public opinion surveys have shown that Croats are deeply dissatisfied with their health care system and asses it to be one of the most important issues. However, health care hardly makes it into any political discourse in Croatia. This study analyzes the results of a public opinion survey conducted before the 2007 parliamentary elections to find out what the public sentiment on health care performance in Croatia is and to analyze the reasons why health care is not addressed by political actors. Evidence suggests that while health care is the most salient issue today, the public often understands it poorly. Thus, in a political environment of competing issues, and given the complexity of tacking health care in the policy arena, politicians strategically avoid discussing the issue.

Estimating preferences for local public services using migration data.

Using Swedish micro data, the paper examines the impact of local public services on community choice. The choice of community is modelled as a choice between a discrete set of alternatives. It is found that, given taxes, high spending on child care attracts migrants. Less conclusive results are obtained with respect to the role of spending on education and elderly care. High local taxes deter migrants. Relaxing the independence of the irrelevant alternatives assumption, by estimating a mixed logit model, has a significant impact on the results.

Racialized customer service in restaurants: a quantitative assessment of the statistical discrimination explanatory framework.

Despite popular claims that racism and discrimination are no longer salient issues in contemporary society, racial minorities continue to experience disparate treatment in everyday public interactions. The context of full-service restaurants is one such public setting wherein racial minority patrons, African Americans in particular, encounter racial prejudices and discriminate treatment. To further understand the causes of such discriminate treatment within the restaurant context, this article analyzes primary survey data derived from a community sample of servers (N = 200) to assess the explanatory power of one posited explanation­statistical discrimination. Taken as a whole, findings suggest that while a statistical discrimination framework toward understanding variability in servers' discriminatory behaviors should not be disregarded, the framework's explanatory utility is limited. Servers' inferences about the potential profitability of waiting on customers across racial groups explain little of the overall variation in subjects' self-reported discriminatory behaviors, thus suggesting that other factors not explored in this research are clearly operating and should be the focus of future inquires.

Local practice and global data: loyalty cards, social practices, and consumer surveillance.

Monitoring of consumers has become the most widespread mode of surveillance today. Being a multi-billion dollar business, the collected data are traded globally without much concern by the consumers themselves. Loyalty cards are an element with which such data are collected. Analyzing the role of loyalty cards in everyday practices such as shopping, I discuss how new modes of surveillance evolve and work and why they eventually make communication about data protection a difficult matter. Further, I will propose an alternative approach to the study of surveillance. This approach is concerned with local practices, focusing on subjective narratives in order to view surveillance as an integral part of culturally or socially manifested contexts and actions and not to view surveillance as something alien to society and human interaction. This will open up other possibilities to study modes of subjectivity or how individuals situate themselves within society.

Variations in the gender composition of immigrant populations: how they matter.

This paper estimates and interprets empirical shifts in the gender composition of immigrants to add to scholarship about the gendering of international migrations over time. We map shifts in gender ratios using micro-level data that permit us to create age-standardized estimates among adult foreign born stock living in the United States since 1850 and in 26 other nations worldwide since 1960. We examine regional and national variations in these shifts, and ask whether and how the gendered composition of foreigners from diverse origins in the United States ­ the nation that has received the largest populations of migrants for over a century ­ differs from other nations that receive large numbers of immigrants. We also examine recent variations in gender ratios among immigrants living in six regional destination countries. Results show substantial variation in the gender composition of foreign-born populations, and they offer a starting point for examining causes and consequences in future research.

Advertising media and cigarette demand.

Using state-level panel data for the USA spanning three decades, this research estimates the demand for cigarettes. The main contribution lies in studying the effects of cigarette advertising disaggregated across five qualitatively different groups. Results show cigarette demand to be near unit elastic, the income effects to be generally insignificant and border price effects and habit effects to be significant. Regarding advertising effects, aggregate cigarette advertising has a negative effect on smoking. Important differences across advertising media emerge when cigarette advertising is disaggregated. The effects of public entertainment and Internet cigarette advertising are stronger than those of other media. Anti-smoking messages accompanying print cigarette advertising seem relatively more effective. Implications for smoking control policy are discussed.

Determinants of pollution: what do we really know?

The recent literature proposes many variables as significant determinants of pollution. This paper gives an overview of this literature and asks which of these factors have an empirically robust impact on water and air pollution. We apply Extreme Bound Analysis (EBA) on a panel of up to 120 countries covering the period 1960­2001. We find supportive evidence of the existence of the environmental Kuznets curve for water pollution. Furthermore, mainly variables capturing the economic structure of a country affect air and water pollution.

The effect of education on cognitive ability.

This paper analyzes whether schooling increases intelligence measured by intelligence quotient (IQ). We use a longitudinal dataset where the individuals have conducted IQ tests both at ages 10 and 20. We estimate the effect of schooling on IQ at age 20 conditional on IQ at age 10 and other measures of early cognitive ability to account for selection into noncompulsory schooling. Ordinary least squares estimates indicate that 1 year of schooling increases IQ by 2.9­3.5 points (about 0.2 SD deviations), and instrumental variables estimates are similar.

The relevance of personal characteristics in health care rationing: what the Australian public thinks and why.

This article examines the preferences of the general public in Australia regarding health care resource allocation. While previous studies have revealed that the public is willing to give priority to particular groups of patients based on their personal characteristics, the present article goes beyond previous efforts in attempting to explain these results. In the present study, there was strong support among respondents for giving "equal priority" to people regardless of their personal characteristics. However, respondents did reveal a preference for married patients over single, for children over adults, for carers of children and the elderly, sole breadwinners, and good community contributors. Further, they would give a lower priority to those perceived as "self-harmers"­smokers, individuals with unhealthy diets, and those who rarely exercise. Variation in the answers according to broad economic and social beliefs across seven different categories ("factors") influenced the pattern of the public's attitudes towards rationing. The Principal Components Analysis (PCA) indicated that most of the items in our survey are associated with seven factors that explain or capture much of the variation. These relate to a patient's avoidance of self-harm behaviors (Safe Living), their Life Style (diet, exercise, etc.), their contribution to the community through caring for others (Caring), their talents (Gifted), their sexual behavior (Sexuality), their age and marital status (Family), and whether they are an Australian citizen or employed (Citizen). The strength of social preferences­e.g., how strongly respondents would "discriminate" against a recreational drug user or preference a person with a healthy diet­is related to the particular class of preferences.

Religion and attitudes toward abortion and abortion policy in Brazil.

This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.

Population momentum across the demographic transition.

Population momentum is the main driver of global population growth today, and this makes an appreciation of momentum critical to understanding contemporary worldwide growth dynamics. This article traces population momentum along with two recently defined measures of momentum decomposed­stable and nonstable momentum­across the demographic transition. We use historical data and population projections from 16 countries to illustrate some previously ignored empirical regularities of the demographic transition in both the developed and the developing world. We also demonstrate the dynamic nature of stable and nonstable momentum, as changes in stable momentum lead to predictable changes in current and future nonstable momentum. These results suggest that momentum, which by definition is measured at a point in time, can also be considered as a process that unfolds over time.

From closed ranks to open doors: Elaine and John Cummings' mental health education experiment in 1950s Saskatchewan.

During late 1951 and early 1952, married couple, social biologist Elaine Cumming and psychiatrist John Cumming, led a mental health education experiment in Indian Head, Saskatchewan. The study, which was intended to inform strategies toward deinstitutionalization, sought to determine if attitudes regarding mental illness could be changed through commonly used educational practices. It was shaped by the shared interests of powerful philanthropic, charitable, psychiatric, academic and governmental bodies to create healthier citizens and a stronger democratic nation through expert knowledge. However, in addition to the disappointing findings indicating that attitudes remained unchanged, the town appeared to close ranks against the research team. Nonetheless, the Cummings' later association with sociologists at Harvard University enabled them to interpret the results in a way that lent the study credibility and themselves legitimacy, thus opening the door to their careers as very successful researchers and policy-makers.
