GOODNESS-OF-FIT TESTS FOR FISHER'S DISTRIBUTION ON THE SPHERE

A set of three goodness-of-fit procedures is proposed to investigate the adequacy of fit of Fisher's distribution on the sphere as a model for a given sample of spherical data. The procedures are all based on standard tests using the empirical distribution function.     

Social problems clusters as contexts for claimsmaking: implications for the study of off-campus housing

ABSTRACT

Many social problems claims occur in a context that involves (1) actors’ recognition of other stakeholders, (2) relationships among those actors, and (3) varying temporal frameworks that influence how each claimsmaker views the current collection of issues. We call actors’ involvement in overlapping issues a social problems cluster, a set of claimsmaking efforts that involve many of the same people and groups as advocates, or opponents. Using a case study of local student housing issues as an example, we suggest the following regarding the social problems cluster. First, we consider how the interactions among social problems cluster members shape what happens with a particular issue. Second, we consider the way participants within one social problems cluster recognize links may reflect participants’ biographies, interests, ideologies, and so forth. Attending to how the social problems cluster’s members interact and link issues helps to locate a particular claim within its broader context.     

Economic Interests and the Vindication of Deviance: Tobacco in Seventeenth Century Europe*

Sociologists have tended to neglect vindication, the process by which deviant behavior becomes redefined as respectable or legitimate. The few studies emphasize the importance of moral persuasion in bringing about vindication. Tobacco's early history suggests that economic interests can also play an important role. In the early seventeenth century, Europeans viewed tobacco as a deviant drug; but in spite of continued moral opposition, it was vindicated by the end of the century because powerful persons and agencies discovered that supporting the trans-Atlantic tobacco trade was in their economic interest.     

The effect of categorisation on testing for an exponential scale shift

A consequence of the fact that observations of random variables are discrete, is that the usual continuous models are inappropriate. Observations have an induced multinomial distribution where the cell probabilities depend on the form of the unobservable continuous distribution. We discuss one particular case: testing for the scale parameter of an exponential distribution. Sizes, powers and asymptotic relative efficiencies are used to assess the effect of categorisation. There are many parameters and we have not given a complete assessment. However our discussion gives a guide to the approach that may be adopted in similar cases. In the case we discuss, we give a preferred procedure that appears to be more convenient and less objectionable than its obvious competitors.     

Effects of work scheduling on time-income tradeoffs

Existing theory and data on work--leisure preferences suggest that how work and free time are scheduled may influence workers' preferences regarding the exchange of income for free time. In general, hours and income are not traded in a strict one-to-one fashion; rather, the value of leisure time is in part a function of the "lumps" in which free time is made available. Exploratory research on an accidental sample of 248 employees in ten work organizations supports this hypothesis. Some societal implications of these findings are discussed.     

Immune responses to low back pain risk factors

$\underline{Objective}$: Investigate effects of interactions between biomechanical, psychosocial and individual risk factors on the body's immune inflammatory responses. $\underline{Background}$: Current theories for low back pain causation do not fully account for the body's response to tissue loading and tissue trauma. $\underline{Methods}$: Two groups possessing a preference for the sensor or intuitor personality trait performed repetitive lifting combined with high or low mental workload on separate occasions. Spinal loading was assessed using an EMG-assisted subject-specific biomechanical model and immune markers were collected before and after exposure. $\underline{Results}$: Mental workload was associated with a small decrease in AP shear. Both conditions were characterized by a regulated time-dependent immune response making use of markers of inflammation, tissue trauma and muscle damage. Intuitors' creatine kinase levels were increased following low mental workload compared to that observed in Sensors with the opposite trend occurring for high mental workload. $\underline{Conclusions}$: A temporally regulated immune response to lifting combined with mental workload exists. This response is influenced by personality and mental workload.     

Bringing Sociology into the Public Policy Process: a Relational Network Approach

How does evidence-based sociological research influence public policymaking either directly or indirectly? Based on an analysis of a 2014 NSF-funded public policy research workshop and written case studies by workshop participants, this article provides a conceptual roadmap and varied examples of the pathways through which social science research and social scientists can inform public policy decision-making. Pathways include networks and relationships among academics, social scientists employed in government, special interest groups and non-profits, and members of the media. Many sociologists are committed to using their evidence-based findings to inform solutions to societal problems, yet are often too narrowly trained to write only for scholarly communities and are often unaware of the relations, connections, and networks that can increase the use of sociological and other social science research in public discourse and in the public policy arena. The paper highlights lessons learned about effective networks, communication channels and dissemination strategies from the workshop and case studies in order to better equip those social scientists interested to bring their research into a public policy realm with the tools to do so. Given the current political climate, this resolve seems all the more important.     

Comparing Nonparametric Tests of Equality of Means for Randomized Block Designs

A number of nonparametric tests are compared empirically for a randomized block layout. We assess tests appropriate for when the data are not consistent with normality or when outliers invalidate traditional analysis of variance (ANOVA) tests. The objective is to assess, within this setting, tests that use ranks within blocks, the rank transform procedure that ranks the complete sample and continuous analogs of the Cochran–Mantel–Haenszel tests. The usual linear model is assumed, and our primary foci are tests of equality of means and component tests that assess linear and quadratic trends in the means. These tests include the traditional Page and Friedman tests. We conclude that the rank transform tests have competitive power and warrant greater use than is currently apparent.     

Popular Hazards and Policy Rhetoric

Popular hazards are common activities that involve some risks of harm, such as driving a car, possessing or shooting a gun, drinking alcohol, or smoking marijuana. In each of these cases, many millions of Americans engage in the activity, but only a small fraction of them harm themselves or other people. Because the activity is so common, the number harmed may be substantial, although more serious harms tend to be much more infrequent than less serious harms. Social policy debates almost always focus on some particular popular hazard, yet we can see rhetorical similarities—parallel arguments—in how advocates frame what are understood to be very different social issues. Thus, discourse about legalizing recreational marijuana use tends to invoke claims that are quite similar to those opposing further gun control. The category of popular hazards allows us to recognize parallels in policy debates about seemingly unrelated social issues. Focusing on the underlying policy issue—balancing popularity and hazardousness—encourages considering alternative ways to construct social policies.
