A Model for Quantitatively Analyzing Representations of Social Class in Screen Media

Content analyses of prime-time television provide a picture of predominant cultural stereotypes and social trends. The present research is a quantitative content analysis of social class in popular broadcast and cable television in the United States. This research advances scholarship by systematically analyzing character class in addition to more commonly examined variables such as race and gender. A model for the operationalization of class for quantitative content analyses of mediated texts is offered. This proof of concept study demonstrates the viability of studying media representations of class quantitatively to systematically document patterns of portrayal.     

A Geohistorical Study of ‘The Rise of Modern Science’: Mapping Scientific Practice Through Urban Networks, 1500–1900

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the ‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of knowledge that relate to, but do not mirror, material changes in the system.

Intercultural contacts and acculturation resources among International students in Australia: A mixed-methods study

This paper explores the impact of acculturation conditions, orientations and outcomes on international students in Australia’s tertiary education sector. Specifically, we investigate the factors that facilitate or hinder acculturation of international students within a multidimensional acculturation context (Arends-Tóth & van de Vijver, 2006). We used a sequential exploratory mixed-methods design in two studies to investigate acculturation of international students at an Australian university and test how these factors are related to psychological and sociocultural outcomes. In Study 1, we conducted a generic qualitative study using semi-structured interviews with a conventional content analyses approach,which compared the experiences of international students who on average had high numbers of positive experiences versus those who had high numbers of negative experiences. We found that a support network of mixed-nationals, and especially host locals, facilitates positive psychological and sociocultural adjustment, and buffers acculturative stress. Study 2 quantitatively tested the association of factors found in Study 1 (perceived stereotypes, intercultural and ethnic network/resources) with psychological and sociocultural acculturation outcomes. Study 2, shows that perceived negative stereotypes loosen ties with the dominant (host) culture and reinforces ties with the ethnic (non-host) culture. The social resources associated with either culture was found to be useful for acculturation, with both independently contributing to participant well-being. Contact with host locals played a particularly crucial role in developing these resources. Our findings provide foundations for pragmatic policy implications, suggesting value in the development of formally organized contact programs in the early sojourn experience of international students.     

Realism Matters: The Role of Perceived Realism in The Biggest Loser

This study investigated implications of viewing The Biggest Loser, NBC’s popular reality television show. Using online survey data collected from 613 participants, results suggest that exposure to the program is positively associated with perceived realism of the program, which in turn is positively associated with developing internal weight locus of control. Meanwhile, internal weight locus of control is positively associated with audience members’ exercise behavior, meaning the higher level of internal weight locus of control the audience members develop, the more likely they are to engage in physical exercise. This study offers evidence that health-related reality television might be a useful tool to influence audience members’ cognitions on health issues, which could potentially lead to healthy lifestyles.
