PUBLIC PERCEPTIONS OF TELEVISION INFLUENCE AND OPINIONS ABOUT CENSORSHIP IN SINGAPORE

It is a common assumption that in many countries mass mediacensorship is imposed by an authoritarian government on an unwillingpublic. This study examines public opinion about televisioncensorship in the island nation of Singapore. More specifically,we tested the third-person effect hypothesis, which suggeststhat people expect media content to have more negative influenceon others than on themselves, and that some support for censorshipis based on that perceptual bias. Data for the study came from face-to-face interviews with 506randomly selected Singaporeans who evaluated ten categoriesof ‘sensitive’ television content. Results revealed(1) a substantial perceptual bias in all content categories;(2) generally strong opinion favoring censorship of televisioncontent; and (3) a significant relationship between these twofactors, suggesting that people may support censorship of mediain part because of a tendency to overestimate its negative influence.     

Latent inhibition as a performance deficit resulting from CS—context associations

Treatments that attenuate latent inhibition (LI) were examined using conditioned suppression in rats. In Experiment 1, retarded conditioned responding was produced by nonreinforced exposure to the CS prior to the CS-US pairings used to assess retardation (i.e., conventional LI). In Experiment la, retarded conditioned responding was induced by preexposure to pairings of the CS and a weak US prior to retardation-test pairings of the CS with a strong US (i.e., Hall-Pearce [1979] LI). Both types of LI were attenuated by extensive exposure to the training context (i.e., context extinction) following the CS-US pairings of the retardation test. Experiment 2 examined the specificity of the attenuated LI effect observed in Experiment 1. After preexposure to two different CSs in two different contexts, each CS was paired with a US in its respective preexposure context. One of the two contexts was then extinguished. This attenuated LI to a greater degree for the CS that had been trained in the extinguished context. Experiment 3 differentiated the roles in LI of CS-context associations and context-US associations. Following preexposure to the CS in the training context, LI was reduced by further exposure to the CS outside the training context. This observation was interpreted as implicating the CS-context association as a factor in LI. Thus, the results of these experiments suggest that LI is a performance deficit mediated by unusually strong CS-context associations. Implications for Wagner’s (1981) SOP model and Miller and Matzel’s (1988) comparator hypothesis are discussed.     

Use of performance-enhancing drugs and the Internet

The use of physical performance-enhancing drugs is not limited to professional sports only, but has also been reported as common practice in recreational sports. A significant amount of epidemiological studies have highlighted the collective of fitness center visitors to be a high-risk group for using performance-enhancing drugs. From a sociological perspective, however, the decision to use performance-enhancing drugs (e.g., doping in the context of high-performance sport) is not an individual phenomenon only, but rather a result of social opportunity structures. This research article gives insight into enhancing-related Internet forums, in which the expertise of using and applying substances is passed on step by step. Using selected criminological learning theories, the “doping talk” in these social networks is hermeneutically reanalyzed and the Internet is exposed as a previously under-analyzed option for acquiring knowledge on the use of performance-enhancing drugs. This article shows that users of “doping platforms” are highly informed about doping and this offer of information acts like a knock-on effect to athletes who have so far abstained from doping. Consequently, future prevention models against the abuse of performance-enhancing drugs should consider the subcultural background of the milieu in which the athletes act.     

Using Data Analysis Exercises to Teach Research in Sociology of Aging Online: An Examination of Student Satisfaction

The present study represents an evaluation of the implementation of the integration of the American Sociological Association's (ASA) Integrating Data Analysis Project into 2 online offerings of an undergraduate sociology of aging course. This program was developed in response to concerns that students did not understand the complex relationships between theory, research, and substantive topics within the discipline. The association's goal was to encourage curricular change in sociology. Then it was to share the experiences in sociology with other social science disciplines that might also benefit from introducing quantitative literacy components into their curricula. Results of the analysis reveal that, contrary to the beliefs of many, the students in these 2 courses found these modules to be beneficial in helping them to better understand the empirical nature of sociology. Many students even expressed an interest in participating in future research projects in sociology and/or other disciplines. We concluded that the students were not overly anxious about the quantitative literacy components of the course. Also, including online data analysis strategies using publicly available data and the complimentary software available at the sites offering these data represent cost and time-effective methods of introducing quantitative literacy into the aging studies classroom.     

Measuring Multidimensional Subjective Well-Being with the I COPPE Scale in a Hispanic Sample

The purpose of this study was to provide initial validity evidence for measuring multidimensional subjective well-being in a Hispanic sample with the Interpersonal, Community, Occupational, Physical, Psychological, Economic (I COPPE) Scale. Participants were 641 English-speaking adults who self-identified as Hispanic. Bi-factor analyses were used to evaluate (a) the a priori measurement theory for responses to the I COPPE Scale and (b) convergent relationships of the seven I COPPE subjective well-being factors with scores from established comparison instruments. There was evidence that (a) the a priori hypothesized measurement theory for responses to the I COPPE Scale emerged in an exploratory bi-factor analysis and (b) the I COPPE subjective well-being factors exhibited convergent relationships with scores from comparison instruments. Use of the I COPPE Scale to derive multidimensional measures of subjective well-being may be of potential utility to future research in the interdisciplinary study of human movement and in a diversity of populations in which health disparities may exist.     

Acute modification in plasma lipid levels in ultramarathon runners

We aimed to evaluate the effects of a 24-h ultramarathon, an aerobic test of high physical load, on lipid profile and apolipoproteins B (ApoB) and A1 (ApoA1) levels, minimally modified low-density lipoprotein (LDL), and oxidised LDL. Prospective evaluation of 16 male athletes who participated in an ultramarathon run, where the objective was to run the greatest distance possible in 24 h. Fourteen participants completed the run. The mean distance achieved was 133.1 km (maximum of 169.6 km). There was a trend in reduction of triglycerides and total cholesterol (P = 0.06 and 0.05, respectively), without significant modifications in high-density lipoprotein, LDL and ApoA1 levels (P = 0.16; 0.55 and 0.67). There was a marked reduction in ApoB levels (P < 0.001), correlated directly to the distance covered (Pearson R = 0.68). Accordingly, an increase in the LDL/ApoB ratio was observed. The stress of this physical activity was not associated to an increase in minimally modified LDL or oxidised LDL. Lipid profile levels were not acutely altered by prolonged physical activity. Similarly, there was no evidence of greater oxidation of LDL over a 24-h period of physical activity. The reduction in ApoB was directly proportional to the distance covered, suggesting an acute positive change in phenotype of LDL molecules.
