Do resources of network members help in help seeking? Social capital and health information search

Does social capital as resources of network members affect health information search? Analyzing data from the 2004 General Social Survey in the United States, this study measures two social capital indicators (average education of network members and proportion of network members with a high school degree or higher) using the name generator. Most results are consistent using those two indicators. Both indicators are positively associated with frequency of health information seeking and seekers’ frequency of use of two sources (friends or relatives and the Internet). Also average education of network members is positively associated with seekers’ diversity of used sources and frequency of consultation with medical professionals. But neither indicator is associated with seekers’ frequency of use of other four sources (health-related magazines or newsletters, general magazines, daily newspapers, and radio or television programs). The findings demonstrate the theoretical utility of social capital in the social dynamics of medical help-seeking.     

Statistical estimation of internal available bandwidth

This paper presents a method for using end-to-end available bandwidth measurements in order to estimate available bandwidth on individual internal links. The basic approach is to use a power transform on the observed end-to-end measurements, model the result as a mixture of spatially correlated exponential random variables, carryout estimation by moment methods, then transform back to the original variables to get estimates and confidence intervals for the expected available bandwidth on each link. Because spatial dependence leads to certain parameter confounding, only upper bounds can be found reliably. Simulations with ns2 show that the method can work well and that the assumptions are approximately valid in the examples.

The Subpoena of Ethnographic Data

This essay outlines the author's experience of having his ethnographic data subpoenaed. It outlines the challenges of subpoena's to research, and suggests four solutions: (1) Apply for and utilize the National Institutes of Health certificate of confidentiality by asking health‐related questions over the course of one's research; (2) Establish a task force that articulates clear ethical guidelines for ethnographic research, with attention to the conditions wherein ethnographers can break confidentiality (and might also comply with subpoenas). These ethical guidelines should then be made clear to research subjects as a part of informed consent processes; (3) Demand that institutions (institutional review boards) that require confidentiality as a condition of research be required to defend that confidentiality through the office of the general counsel; (4) Socialize the cost of subpoenas, wherein scholars can be part of an insurance pool that will defend them in the event of a subpoena and thereby defend the general enterprise of ethnographic research.     

Toward a model of school inspections in a polycentric system

Many education systems are developing towards more lateral structures where schools collaborate in networks to improve and provide (inclusive) education. These structures call for bottom-up models of network evaluation and accountability instead of the current hierarchical arrangements where single schools are evaluated by a central agency. This paper builds on available research about network effectiveness to present evolving models of network evaluation. Network effectiveness can be defined as the achievement of positive network level outcomes that cannot be attained by individual organizational participants acting alone. Models of network evaluation need to take into account the relations between network members, the structure of the network, its processes and its internal mechanism to enforce norms in order to understand the achievement and outcomes of the network and how these may evolve over time. A range of suitable evaluation models are presented in this paper, as well as a tentative school inspection framework which is inspired by these models. The final section will present examples from Inspectorates of Education in Northern Ireland and Scotland who have developed newer inspection models to evaluate the effectiveness of a range of different networks.     

Making Professional Decisions in Research: Measurement and Key Predictors

The professional decision-making in research (PDR) measure was administered to 400 National Institutes of Health (NIH)-funded and industry-funded investigators, along with measures of cynicism, moral disengagement, compliance disengagement, impulsivity, work stressors, knowledge of responsible conduct of research (RCR), and socially desirable response tendencies. Negative associations were found for the PDR and measures of cynicism, moral disengagement, and compliance disengagement, while positive associations were found for the PDR and RCR knowledge and positive urgency, an impulsivity subscale. PDR scores were not related to socially desirable responding, or to measures of work stressors and the remaining impulsivity subscales. In a multivariate logistic regression analysis, lower moral disengagement scores, higher RCR knowledge, and identifying the United States as one’s nation of origin emerged as key predictors of stronger performance on the PDR. The implications of these findings for understanding the measurement of decision-making in research and future directions for research and RCR education are discussed.     

Spatial effects on individual social capital: Differentiating the constraints of local occupational structures

Recent studies have paid more attention to how position-generated social capital varies by an individual’s characteristics, and less to how geographical distributions of occupations may constrain position-specific connections. By integrating two national surveys from the United States, we differentiate the extent to which individual social capital fluctuates by occupational compositions at the county, metropolis, and state levels. Multilevel analyses show that when more people at all three levels work in education, training, and library occupations, residents have a greater chance to gain access to professional-type resources. Similar spatial effects on farming and production resources, however, are more apparent at the county level. Not only does the association between individual social capital and local occupational structures vary across different occupations, but the magnitude of such spatial effects also differs by the scope of the geographical areas. The findings underscore how contextual factors and geographical location may contribute to building occupation-specific network resources.     

What drives a tough call: Determining the importance of contingency factors and individual characteristics in communication executives’ stance decision-making through a conjoint analysis

To further the understanding of how communication executives make tough calls in times of organizational-public conflict, we use a conjoint analysis to identify key drivers for organizational stance decision-making. This is the first-ever conjoint analysis applied to advancing the contingency theory of strategic conflict management by examining the relative importance of key contingency factors as determined by practitioners with varied individual characteristics. This study investigates: 1) the relevant importance of and dynamics between three key contingency factors (i.e., external threats, organizational characteristics, and dominant coalition characteristics); 2) the influence of individual characteristics (e.g., gender, experience, and personal ethics) in stance decision-making process; and 3) how different types of organizational stances (i.e., general stance, action-based accommodation, and qualified-rhetoric-mixed accommodation) are determined by these contingency factors and individual characteristics in different conflict situations. Results generated among our communication executive participants include: individual characteristics (i.e., gender, ethics and social responsibility, whistleblowing tendencies, and over 20 years in the communications field) are influential for their strategic conflict management decision-making. Implications for refining the contingency theory and unearthing complex public relations decision-making processes via novel statistical techniques are discussed.     

Anticipated Ethics and Regulatory Challenges in PCORnet: The National Patient-Centered Clinical Research Network

PCORnet, the National Patient-Centered Clinical Research Network, seeks to establish a robust national health data network for patient-centered comparative effectiveness research. This article reports the results of a PCORnet survey designed to identify the ethics and regulatory challenges anticipated in network implementation. A 12-item online survey was developed by leadership of the PCORnet Ethics and Regulatory Task Force; responses were collected from the 29 PCORnet networks. The most pressing ethics issues identified related to informed consent, patient engagement, privacy and confidentiality, and data sharing. High priority regulatory issues included IRB coordination, privacy and confidentiality, informed consent, and data sharing. Over 150 IRBs and five different approaches to managing multisite IRB review were identified within PCORnet. Further empirical and scholarly work, as well as practical and policy guidance, is essential if important initiatives that rely on comparative effectiveness research are to move forward.
