Disaster response on September 11, 2001 through the lens of statistical network analysis

The rescue and relief operations triggered by the September 11, 2001 attacks on the World Trade Center in New York City demanded collaboration among hundreds of organisations. To shed light on the response to the September 11, 2001 attacks and help to plan and prepare the response to future disasters, we study the inter-organisational network that emerged in response to the attacks. Studying the inter-organisational network can help to shed light on (1) whether some organisations dominated the inter-organisational network and facilitated communication and coordination of the disaster response; (2) whether the dominating organisations were supposed to coordinate disaster response or emerged as coordinators in the wake of the disaster; and (3) the degree of network redundancy and sensitivity of the inter-organisational network to disturbances following the initial disaster. We introduce a Bayesian framework which can answer the substantive questions of interest while being as simple and parsimonious as possible. The framework allows organisations to have varying propensities to collaborate, while taking covariates into account, and allows to assess whether the inter-organisational network had network redundancy-in the form of transitivity-by using a test which may be regarded as a Bayesian score test. We discuss implications in terms of disaster management.

Implementation and Maintenance of a Community-Based Older Adult Physical Activity Program

PURPOSE OF THE STUDY We examine facilitators and barriers to the implementation and maintenance of Enhance®Fitness (EF), a group exercise program for older adults, at early-adopter YMCA-affiliated sites, and summarize strategies employed by EF instructors and staff to overcome challenges. DESIGN AND METHODS This qualitative study used semi-structured phone interviews with 32 instructors, staff members, and master trainers from 24 different YMCA-affiliated sites. Interviews were digitally recorded, transcribed, and analyzed with a focus on the implementation and maintenance components of the RE-AIM framework. RESULTS We identified a series of factors affecting the implementation and maintenance of EF at YMCA-affiliated sites, which can be categorized into program-specific (such as instructor training, the structure of the program, reporting requirements, and insurance coverage), and organizational (such as organizational support and infrastructure for program delivery, champions, and funding to cover the costs of program delivery). Strategies used to overcome challenges associated with these factors include identifying parts of the program that can be adapted, hiring staff and instructors that understand and support the program, and educating staff and instructors about the importance of evidence-based programs and of data collection for program evaluation. IMPLICATIONS Assessing the readiness of organizations for program delivery and the match between program goals and the needs of organizations and participants would help facilitate the successful implementation and maintenance of physical activity programs in community settings.

Beyond Strength Participant Perspectives on the Benefits of an Older Adult Exercise Program

This study examines the expected and experienced benefits among participants in Enhance®Fitness (EF), an evidence-based group physical activity program for older adults. We also describe the implications for program dissemination (reach, implementation, and maintenance) within the RE-AIM (reach, effectiveness, adoption, implementation, and maintenance) framework. Twenty semistructured interviews were conducted with EF participants enrolled from 2005 to 2012. Interviews were digitally recorded, professionally transcribed, and analyzed using a deductive approach. Participants were motivated to join EF for expected physical benefits and the social environment of a group-based class. Actualized benefits of participation included physical, social, functional, and improved self-image/sense of well-being. Participants valued the practical application of class exercises to daily activities that support independent living, such as lifting objects and completing household chores. Organizations looking to implement EF or improve existing EF classes can improve program reach, implementation, and maintenance by incorporating participants’ expressed motivations and valued benefits in program marketing and by improving organizational support to meet participant needs. EF class instructors can tailor their classes to engage participants based on their motivations. Understanding participants’ motivations and valued benefits can improve EF dissemination by meeting participant needs with tailored class offerings and organizational needs informed by participant insights that aid program sustainability.

Adoption of Evidence-Based Health Promotion Programs: Perspectives of Early Adopters of Enhance®Fitness in YMCA-Affiliated Sites

Purpose To identify facilitators and barriers among early adopters of Enhance®Fitness (EF), in Young Men’s Christian Association-affiliated (Y-affiliated) sites from the perspective of program staff. EF is an evidence-based group exercise program for seniors. Methods This qualitative study used semi-structured phone interviews with 15 staff members representing 14 Y-affiliated sites. Interviews were digitally recorded, transcribed, and analyzed using qualitative content analysis informed by the RE-AIM framework. Findings Staff were, on average, 48.7 years old (SD 13.5) and had been involved with EF for 5.2 years (SD 3.1). Key themes related to facilitating adoption of EF were: match with the Y mission, support from different organizational levels, match between the target population need and EF, initial and on-going financial support, presence of champions, novelty of EF, an invitation to partner with a community-based organization to offer EF, and program-specific characteristics of EF. Key themes related to barriers interfering with EF adoption included competing organizational programs and space limitations, limited resources and expertise, and costs of offering the program. Implications Our findings identify the types of organizational support needed for adoption of evidence-based health promotion programs like EF. Recommendations for practice, research, and policy based on the findings, including assessing organizational readiness, researching late adopters, and developing revenue streams, may help facilitate program adoption. Packaging and sharing these practical recommendations could help community-based agencies and nationally networked organizations facilitate adoption of EF and other evidence-based programs.

Involving immigrant religious organizations in HIV/AIDS prevention: The role of bonding and bridging social capital

Immigrant religious organizations in the United States are uniquely positioned to address critical issues beyond religion because of their moral, social and cultural prominence in community life. Increasingly, religious organizations have taken on a leadership role around health issues such as decreasing HIV/AIDS stigma and misinformation. However, there are barriers for some religious leaders and organizations in adopting new health programs, especially if the issue is seen as controversial. Our study examines how social network structures among religious members influence organizational acceptance of new information or controversial ideas, like HIV/AIDS. Using social network analysis methods on data from 2841 contacts in 20 immigrant Chinese Buddhist temples and Christian churches in New York City, we tested whether an immigrant religious organizations likelihood of being involved in HIV/AIDS activities was associated with the presence of bonding or bridging social capital. These two forms of social capital have been found to mediate the levels of exposure and openness to new ideas. We found HIV/AIDS-involved religious organizations were more likely to have lower levels of bonding social capital as indicated by members having fewer ties and fewer demographic attributes in common. We also found HIV/AIDS-involved religious organizations were more likely to have higher levels of bridging social capital as indicated by members having significantly more ties to people outside of their organization. Our study highlights the importance of looking beyond religion type and leadership attributes to social network structures among members in order to better explain organization-level receptiveness to HIV/AIDS involvement.

Women’s Wage Theft

In this study, the authors identify and analyze a distinct and understudied source of gender inequality: gender differences in violations of wage-related workplace laws. The authors find that women have significantly higher rates of minimum wage and overtime violations than men and also lose more of their earnings to wage theft than men. In the case of minimum wage violations, the authors also find that nativity and immigration status strongly mediate this gender difference. Multivariate analysis suggests that demand-side characteristics—occupation and measures of nonstandard work and informality—account for more of the gender difference in minimum wage violations than do worker characteristics.

Using Social Network Analysis to Assess Mentorship and Collaboration in a Public Health Network

Introduction Addressing chronic disease burden requires the creation of collaborative networks to promote systemic changes and engage stakeholders. Although many such networks exist, they are rarely assessed with tools that account for their complexity. This study examined the structure of mentorship and collaboration relationships among members of the Healthy Aging Research Network (HAN) using social network analysis (SNA). Methods We invited 97 HAN members and partners to complete an online social network survey that included closed-ended questions about HAN-specific mentorship and collaboration during the previous 12 months. Collaboration was measured by examining the activity of the network on 6 types of products: published articles, in-progress manuscripts, grant applications, tools, research projects, and presentations. We computed network-level measures such as density, number of components, and centralization to assess the cohesiveness of the network. Results Sixty-three respondents completed the survey (response rate, 65%). Responses, which included information about collaboration with nonrespondents, suggested that 74% of HAN members were connected through mentorship ties and that all 97 members were connected through at least one form of collaboration. Mentorship and collaboration ties were present both within and across boundaries of HAN member organizations. Conclusion SNA of public health collaborative networks provides understanding about the structure of relationships that are formed as a result of participation in network activities. This approach may offer members and funders a way to assess the impact of such networks that goes beyond simply measuring products and participation at the individual level.

Enhance®Fitness Dissemination and Implementation, : 2010–2015: A Scoping Review

INTRODUCTION Physical activity has many benefits for older adult physical and mental health. Enhance®Fitness (EF) is an evidence-based group exercise program delivered by community-based organizations. The purpose of this study was to review recent evidence on the dissemination and implementation of EF. METHODS A scoping review of qualitative and quantitative studies with EF as main focus was conducted. CINAHL, PubMed, PubMed Central, SCOPUS, Web of Science, PsycINFO, and Google Scholar were searched between October and November 2015 for data-based studies on EF published in 2010-2015. Two team members abstracted each paper independently using a data abstraction tool. Results were summarized using the Reach, Effectiveness, Adoption, Implementation, and Maintenance (RE-AIM) framework. RESULTS Seventeen publications met inclusion criteria. EF has reached and is effective across a broad population base, including individuals with low SES and diverse ethnic/racial backgrounds. EF participation may be associated with reduced risk for falls requiring medical care, and is associated with fewer hospital admissions. Analyses of medical cost savings from EF participation and program implementation costs suggest economic benefits of EF implementation for communities. Organization-level maintenance is facilitated by program-specific and organizational factors, such as instructor training and funding. Individual-level maintenance is facilitated by program structure, absence of pain, and increased quality of life. CONCLUSIONS More-rigorous evidence is needed about the association between participation in EF and conditions such as falls. Evaluation of program fidelity, adaptations, and sustainability is limited; more-systematic examination across population groups and types of organizations would help ensure older adults continue to benefit from EF participation.

Champions of an Older Adult Exercise Program: Believers, Promoters, and Recruiters.

Champions, who support, market, and promote programs, are a vital part of successful program adoption, implementation, and maintenance. Enhance®Fitness (EF) is an evidence-based, community-delivered group exercise program for older adults. Using semistructured phone interviews with 20 participants, 17 instructors, and 15 staff, we explored the roles of champions in adopting, implementing, and maintaining EF at YMCA-affiliated sites. Interviews revealed EF champions play critical roles in program dissemination. Champions are outgoing, passionate, and enthusiastic about EF. They believe in the program and its benefits (believers), are “walking advertisements” (promoters), and have magnetic personalities, persuading newcomers to join (recruiters). EF champions were not purposefully selected but naturally arose during the course of program delivery. Community sites adopting evidence-based programs can foster and support champions by engaging with them, and capitalizing on their energy as an emerging resource throughout the adoption, implementation, and maintenance of programs.

Bridging the Gap After Physical Therapy: Clinical–Community Linkages With Older Adult Physical Activity Programs

Abstract Background and Objectives Many barriers exist to older adult participation in physical activity, despite known benefits. Referrals from physical therapists (PTs) through clinical–community linkages offer novel, promising opportunities to increase older adult engagement in appropriate community-based physical activity programs. We assessed the capacity of PTs to participate in such linkages. Research Design and Methods We collected qualitative data using semistructured phone interviews (n = 30) with PTs across 14 states. We conducted thematic analysis using a priori themes based on the 2008 Bridging Model of Etz and colleagues: capacity to assess patient risk, ability to provide brief counseling, capacity and ability to refer, and awareness of community resources. Results Risk assessment and counseling were already part of routine practice for our respondents, but counseling could be further facilitated if PTs had more skills to engage less-motivated patients. PTs expressed a desire to refer their patients to community programs; however, barriers to referrals included lack of knowledge of and trust in community programs, and limited infrastructure for communicating with potential partners. Discussion and Implications PTs have the capacity to develop patient referral linkages with community-based physical activity programs. PT session length and content facilitates patient risk assessment and behavioral counseling. Integrating motivational techniques can help PTs engage less-motivated patients in physical activity. Systemic improvements should include innovations in communication infrastructure, identifying clinic-level champions, and in-person outreach initiated by organizations that deliver community physical activity programs.
