RESUMO

Establishing sustainable communities requires bridging the gap between academic knowledge and societal requirements; this is where entrepreneurial education comes in. The first phase involved a comprehensive review of the literature and extensive consultation with experts to identify and shortlist the components of entrepreneurship education that support sustainable communities. The second phase involved Total Interpretative Structural Modelling to explore or ascertain how the elements interacted between sustainable communities and entrepreneurial education. The factors are ranked and categorized using the Matrice d'impacts croises multiplication appliquee an un classement (MICMAC) approach. The MICMAC analysis classifies partnerships and incubators as critical drivers, identifying Student Entrepreneurship Clubs and Sustainability Research Centers as dependent elements. The study emphasizes alumni networks and curriculum designs as key motivators. The results highlight the critical role that well-designed entrepreneurial education plays in developing socially conscious entrepreneurs, strengthening communities, and generating long-term job prospects. The study provides a valuable road map for stakeholders dedicated to long-term community development agendas by informing the creation of strategic initiatives, curriculum updates, and policies incorporating entrepreneurial education.

RESUMO

BACKGROUND: Asset-based approaches (ABAs) tackle health inequalities by empowering people in more disadvantaged communities, or targeted populations, to better utilise pre-existing local community-based resources. Using existing resources supports individuals to better manage their own health and its determinants, potentially at low cost. Targeting individuals disengaged with traditional service delivery methods offers further potential for meaningful cost-savings, since these people often require costly care. Thus, improving prevention, and management, of ill-health in these groups may have considerable cost implications. AIM: To systematically review the extent of current cost and economic evidence on ABAs, and methods used to develop it. METHODS: Search strategy terms encompassed: i) costing; ii) intervention detail; and iii) locality. Databases searched: Medline, CENTRAL and Wed of Science. Researchers screened 9,116 articles. Risk of bias was assessed using the Critical Appraisal Skills Programme (CASP) tool. Narrative synthesis summarised findings. RESULTS: Twelve papers met inclusion criteria, representing eleven different ABAs. Within studies, methods varied widely, not only in design and comparators, but also in terms of included costs and outcome measures. Studies suggested economic efficiency, but lack of suitable comparators made more definitive conclusions difficult. CONCLUSION: Economic evidence around ABAs is limited. ABAs may be a promising way to engage underserved or minority groups, that may have lower net costs compared to alternative health and wellbeing improvement approaches. ABAs, an example of embedded services, suffer in the context of economic evaluation, which typically consider services as mutually exclusive alternatives. Economics of the surrounding services, mechanisms of information sharing, and collaboration underpin the success of assets and ABAs. The economic evidence, and evaluations in general, would benefit from increased context and detail to help ensure more nuanced and sophisticated understanding of the economics of ABAs. Further evidence is needed to reach conclusions about cost-effectiveness of ABAs.

RESUMO

To understand the core aspects of an empowerment-based Community Health Worker (CHW) training program, we studied the model of the Comprehensive Rural Health Project (CRHP) in Jamkhed, India-an organization known for facilitating empowerment of women as Village Health Workers (VHWs) and agents of community change. We define empowerment as a means by which individuals gain health and development-related skills and knowledge to facilitate positive change within their lives and communities. Using VHW training observations and semi-structured interviews with health workers and senior trainers, 6 themes were developed and applied in 4 focus group sessions with 18 multigenerational VHWs trained by the CRHP. Transcripts were qualitatively analyzed under 6 themes-selection, baseline training, continuing education and support, community participation, community empowerment, and commitment and longevity. Empowerment of VHWs was found to be an intentional process involving the creation of safe and supportive environments conducive to long-term participatory and experiential learning with professionals who facilitate and mentor. The impact of the baseline training is maintained through ongoing program-VHW interactions and knowledge reinforcement in both the field and training center. Importantly, these interactions reinforce VHWs' credibility and confidence in communities served. Community participation was found to be of key importance starting at the selection phase. The methods used for selection, training and ongoing support are critical to developing a cadre of competent, effective and motivated VHWs as well as fostering long-lasting self-development and leadership skills. Downstream effectiveness of community empowerment on health outcomes is demonstrated through indicators such as access to safe deliveries, declining child malnutrition rates, high vaccination rates as well as reductions in stigmatization of illness and caste discrimination.

RESUMO

PURPOSE: Evidence suggests differential impacts of community development, including gentrification and displacement. Public health practitioners and advocates are key stakeholders involved in the community development process related to active living, yet little is known about their perceptions of its impacts. We explored the perspectives of relevant leaders of public health departments and key community and advocacy organizations on community development, gentrification, and displacement. APPROACH: Purposive key informant interviews. SETTING: CDC State Physical Activity and Nutrition (SPAN) funding recipients. PARTICIPANTS: CDC SPAN recipient leadership (n = 10 of 16) and advocacy organizations they partnered with (n = 7 of 16). METHOD: Interviews were recorded, transcribed, coded, and thematically analyzed with direct quotes representing key themes. RESULTS: Both groups felt community development held important benefits, specifically by creating healthy living opportunities, but also potentially leading to the displacement of long-time residents. Practitioners reported the benefits were for all community members, whereas advocates noted the benefits were seen in those with privilege, and the consequences were disproportionately seen in disadvantaged communities. Both mentioned the importance and difficulty of getting diverse representation for community engagement. CONCLUSIONS: Learning how key stakeholders perceive and navigate the community development process can help inform recommendations for better equity in active living community improvements. More work is needed to further elucidate best practices for health and social equity in the community development process.

RESUMO

Promotion appears to be the least effective but is nevertheless often the only available, means to achieve increased access to sanitation services, especially at scale, in lower-income countries. A cursory examination of the history of past and present approaches to sanitation promotion, including sanitation marketing, community development, community-led total sanitation and public health, shows that they have a variety of features and characteristics which make them distinctive. Unfortunately, rigorous evaluation has not kept pace with this proliferation of approaches, so it is difficult to recommend any one approach over the others, based on empirical performance in a range of circumstances. However, I argue that a 'hybrid' approach which exhibits a number of salient features from all of the previous approaches is likely to be a good bet. I present a recent example of such a hybrid programme which proved to significantly increase the rate of improved sanitation coverage through promotion (without subsidy of any kind) at scale in Tanzania. I suggest other sanitation promotion programs may want to think about adopting similar practices in their own programming going forward.

RESUMO

BACKGROUND: Surfers play a critical role in coastal drowning prevention, conservatively estimated to make as many rescues as beach lifeguards. The Surfer Rescue 24/7 (SR24/7) program is a coastal safety intervention in Australia and New Zealand that teaches surfers safe rescue skills and promotes prevention activities. This multi-part, mixed-methods study aimed to evaluate the impact of the SR24/7 program. METHODS: The study consisted of three parts employing quantitative and qualitative methods: a retrospective survey of course participants, in-depth interviews with course participants who had conducted rescues, and an analysis of self-reported skills confidence ratings before and after the program. RESULTS: Triangulated results from the three study components indicated that after the course, participants exhibited high levels of satisfaction with their experience in the program and would encourage others to attend, were more observant and aware of safety concerns while surfing, had a better understanding of ocean conditions and hazards, learned new rescue techniques and skills, grasped important course concepts related to their own personal safety, and improved their confidence in responding to an emergency situation. Several participants had conducted rescues in real life and indicated that the course was effective in providing them with the baseline knowledge and skills to keep safe while helping others in the ocean. This study also provides new insight on the role of surfers in coastal safety, specifically that surfers are engaged in a range of prevention activities before rescue is required. CONCLUSIONS: Despite persistent challenges in combating coastal drowning rates, the SR24/7 program is an effective intervention that helps save lives. Importantly, this study provides evidence that the course successfully equips surfers with techniques to act responsibly and safely. Expanding coastal safety focus and resources towards surfers, an often-overlooked demographic in beach safety strategies, could substantially enhance community-level capacity to prevent and respond to ocean emergencies.

RESUMO

INTRODUCTION: Though social networks which are deemed vehicles of community development exist in slum areas, underdevelopment still persists in these areas. We explored the nature and role of social networks in facilitating community development in the slums of Kampala through a sanitation lens. METHODS: Qualitative Social Network Analysis (SNA) was done to understand the nature of slum social networks primarily through the analysis of sanitation behavior. Data were collected through six Focus Group Discussions (FGD), six In-depth Interviews (IDIs), and 18 Key Informant Interviews (KII) with Government, civil society and private stakeholders. We used both inductive and deductive thematic analysis. RESULTS: Four themes emerged in our analysis; i); Unsupportive environments, uncooperative neighbours and uncertainty of tenure: participants reported slums as unsupportive of community development due to a shortage of space, poverty and unplanned services. Tenants perceived landlords as exploitative and predatory and wished the tables are turned. This notion of cyclic exploitation did not encourage collective action for community good. Short-term economic survival trumped long-term community interests ii) Patronage and poor service delivery: varying degrees of patronage led to multiple forms of illegalities and violations such as tax evasion. Due to vested interests and corruption among public officials, the slum population was lethargic. iii) Intersecting realities of poverty and unemployment: slum dwellers lived on the margins daily. Hence, poor living conditions were a secondary concern. iv) Social relations for personal development: Slum social networks were driven by individual interests rather than community good. Slum dwellers prioritized connections with people of common socio-economic interests. As such social networks were instrumental only if they 'added value'. CONCLUSION: Social networks in slums are only concerned about survival needs. Slums require responses that address the complexity of slum formation and broader livelihood challenges, as well as re-assessing the meaning of community. We posit that more needs to be done in understanding the meaning and workings of a sociology beyond physical societies. Poverty is a modifier of social systems and processes and should be a concern for all stakeholders involved in slum development.

RESUMO

Compared to many countries, Cuba has made significant progress in advancing women's rights and gender equity; however, disparities remain. In the country's rural communities and agricultural sector, women continue to face barriers to equal participation and recognition for the value of their work. This case study shares the story of gender equity efforts that have been conducted within the framework of a broader development project-the Project to Strengthen a System of Innovation in Local Agricultural Development (PIAL, for its initials in Spanish). PIAL began in 2001 as a participatory plant-breeding initiative aimed at increasing the genetic diversity of key crops such as maize and beans. Over the course of two decades, the project's goals expanded to include an emphasis on increasing women's participation. In the beginning, those efforts focused on including women in the participatory plant-breeding activities, which enabled them to prioritize traits they cared about such as grain texture, cooking speed, and taste in the selection process. Over time, the participatory nature of the PIAL methodology empowered women to identify and pursue capacity-building in other areas of local agricultural innovation. While PPB remained central to PIAL, women also chose to pursue opportunities in seed bank management, leadership training, and small-scale farm-based entrepreneurship. The results of the PIAL work on gender have included not just more inclusive plant breeding, but also important economic improvements for rural women as they have been able to diversify their livelihoods, and social change as they have gained confidence and recognition as leaders in their households, communities, and beyond.

RESUMO

Microbial Fe(III) reduction is a key component of the iron cycle in natural environments. However, the susceptibility of Fe(III) (hydr)oxides to microbial reduction varies depending on the mineral's crystallinity, and the type of Fe(III) (hydr)oxide in turn will affect the composition of the microbial community. We created microcosm reactors with microbial communities from four different sources (soil, surface water, groundwater, and aerosols), three Fe(III) (hydr)oxides (lepidocrocite, goethite, and hematite) as electron acceptors, and acetate as an electron donor to investigate the shaping effect of Fe(III) mineral type on the development of microbial communities. During a 10-month incubation, changes in microbial community composition, Fe(III) reduction, and acetate utilization were monitored. Overall, there was greater reduction of lepidocrocite than of goethite and hematite, and the development of microbial communities originating from the same source diverged when supplied with different Fe(III) (hydr)oxides. Furthermore, each Fe(III) mineral was associated with unique taxa that emerged from different sources. This study illustrates the taxonomic diversity of Fe(III)-reducing microbes from a broad range of natural environments.

RESUMO

ISSUE ADDRESSED: There is increasing interest across public health research, policy, and practice in place-based approaches to improve health outcomes. Practice-focused resources, such as grey literature, courses and websites, are utilised by practitioners to support the implementation of place-based approaches. METHODS: A detailed search of two search engines: Google and DuckDuckGo to identify free practice-focused resources was conducted. RESULTS: Forty-one resources met inclusion criteria, including 26 publications, 13 web-based resources and two courses. They were mainly focused on collaboration, developed by not-for-profit organisations, focused on a broad target audience, and supported people living with disadvantage. The publications we reviewed generally: clearly stated important information, such as the author of the publication; used their own evaluations, professional experience and other grey literature as supporting evidence; included specific, practical implementation strategies; and were easy to read. CONCLUSIONS: Based on findings, we recommend that: (1) the development of resources to support evidence-informed practice and governance be prioritised; (2) resources clearly state their target audience and tailor communication to this audience; (3) resources draw on evidence from a range of sources; (4) resources continue to include practical implementation strategies supported by examples and (5) resource content be adaptable to different contexts (e.g., different settings and/or target populations). SO WHAT?: This is the first review of practice-focused resources to support the implementation of place-based approaches and the findings can be used to reduce duplication of efforts and inform future research, policy, and practice, particularly the refinement of existing resources and the development of future resources.

RESUMO

Community development and population-oriented approaches are emphasized to advance the occupational therapy profession's scope of practice to meet the increasing demands created by socio-cultural-political and economic changes. This study explored the practice processes of occupational therapists in community settings outside existing health care structures in Germany. Data was gathered through five individual qualitative interviews and one focus group and analyzed using thematic analysis. Three main themes were identified: navigating parallel processes within the larger context or system; building community connections through occupation; growing professional identity. The utilization of occupational science concepts was essential to work successfully on a community level.

RESUMO

This brief argues that "grandmother-exclusionary bias" - or the side-lining of female elders as change agents within FGM/C programmes - represents a major obstacle to eradication of these practices. Grandmother-exclusionary bias is prevalent within FGM/C policy and programming. Yet, it goes against evidence of the extensive authority and decision-making roles that grandmothers wield in relation to FGM/C in sub-Saharan Africa, and insights from systems theory and meta-evaluations of FGM/C eradication efforts which stress that sustained change requires engaging those who wield authority over gender and social norms. We use postcolonial and decolonial theory to explain the assumptions about grandmothers which underpin grandmother-exclusionary bias. Finally, we provide recommendations for designing grandmother-inclusive, intergenerational community-led programmes based on a strategy empirically proven to shift social norms underpinning FGM/C.

RESUMO

Older adults prefer ageing in place (AIP) rather than institutionalized facilities. Although its advantages, AIP can be challenging when communities are unable to meet residents' needs. This study aims to identify the relationship between the level of age-friendliness of community and AIP. We used AARP Age-friendly Community Survey data with 6670 older adults in the USA. We used responses from 63 items assessing various aspects of a community's age-friendliness to identify different types of age-friendly communities (AFCs) through latent profile analysis (LPA). We then ran multinomial logistic regression to examine whether the types of AFC were associated with AIP. LPA revealed three types of AFC: Underdeveloped, developing, and developed. Regression results showed older adults living in underdeveloped and developing communities are less likely to AIP compared to those in the developed community. These results show a positive impact of AFC on intention to AIP. Policymakers should consider expanding AFC initiatives for the growing number of older adults.

RESUMO

Objectives This study aimed to develop scales for evaluating the level of implementation of community practices and explore the perception of public health nurses in municipalities regarding their community practices.Methods Draft scales were developed based on a literature review and interviews with municipal public health nurses. Subsequently, a questionnaire survey was conducted with municipal public health nurses across Japan in response to these draft scales. Respondents were recruited based on the municipality population size. Questionnaires were distributed to 2,074 individuals from 52 municipalities ensuring representation from diverse municipalities. Exploratory factor analysis was performed to determine the number of factors, while confirmatory factor analysis was performed to determine the factor structure. The reliability of the scales was assessed by calculating Cronbach's alpha coefficients, and their validity was tested by examining correlations with existing scales, namely the Moral Competence Scale for Public Health Nurses and the Professional Identity Scale for Public Health Nurses, and years of experience as a public health nurse.Results A total of 721 (34.8%) valid respondents were included in the analysis. Three scales, methods of community practices (three factors, nine items), perceptions of public health nurses toward community residents through community practices (three factors, 10 items), and organizational environment supporting community practices (two factors, 11 items) were developed as indicators of the implementation of public health nurses' community practices. Cronbach's alpha coefficients for the three scales were 0.896, 0.913, and 0.868, respectively. As hypothesized, each subfactor exhibited a positive correlation with the existing scales. However, certain subfactors did not demonstrate any correlation with years of experience.Conclusion The three scales developed in this study were individually examined for reliability and validity. These scales can be used independently or in combination, allowing public health nurses to select the most suitable scale(s) based on their objective. A notable contribution of this study is the establishment of concrete indicators for evaluating community practices, addressing the previously vague nature of this evaluation. By incorporating the scale items into daily health practices, we anticipate that these indicators can be employed to evaluate community practices at the organizational and individual levels.

RESUMO

Background: Numerous enterprises face great challenges during uncertain economic conditions. This is particularly true for micro, small, and medium-scale companies, which are slumped against disruption from the COVID-19 pandemic-owing to lockdowns, decreased demand, and a disrupted supply chain. This has impacted the economy worldwide but also the social community and the environment that forms its ecosystem. Organizational resilience allows for socio-economic growth and enterprises to build environmental sustainability and balanced community development. Therefore, the behavior of companies must be transformed in building entrepreneurship to encourage socio-economic growth. Methods: We conducted an advanced search on Business Source Premier, ABI/INFORM (ProQuest), Emerald Insight, and Web of Science database between March and June 2022. We screened the bibliographies of the articles from the database search using a set of inclusion criteria such as studies with quantitative design with unit analysis population sample based microfinance institutions and cooperative-based microfinance institutions, MSEs, and MSMEs as well as other industries such as travel agents, property, restaurants, food and beverages, manufacturing and plantations; exploration of transformational entrepreneurship behavior and organizational resilience determinant factors and conceptual manuscripts written in English; and published between 2005 till 2019 for transformational entrepreneurship and 1997 till 2000 for organizational resilience.   Results: This study reviewed 22 articles focusing on the role and influence of organizational resilience on transformational entrepreneurship behavior from a lens that posits the importance of organizational resilience in the face of uncertain economic turbulence. The orientation of entrepreneurship behavior has been neglected in research so far. This systematic literature review study reveals important research gaps, such as the influence of organizational resilience in promoting the development of transformational entrepreneurship behavior and the determinants that build organizational resilience. Conclusions: Research related to a company's transformational entrepreneurship behavior offers a broad area of ​​scientific research; hence, encouraging further investigation is necessary.

RESUMO

Communities of color are disproportionately impacted by gun violence. Unlocking potential community-led solutions could be the key to quelling the gun violence epidemic and its impact on these communities. In this qualitative study, we explored community perspectives on local assets that may prevent and mitigate gun violence. We conducted semi-structured, in-depth interviews (n = 45) among individuals not directly involved in gun violence (i.e., shooting victim or perpetrator) despite having a high probability of being involved in gun violence in New Haven, CT. Participants were asked to describe social structures that may deter local gun violence. Here, we report emergent themes to preventing gun violence across multiple levels, including role models (interpersonal), social cohesion and home ownership (neighborhood), and community-based organizations (organizational). Our findings suggest that investments in stable housing, efforts to build social cohesion, access to community-based mental health services, and youth activities are needed to curb the drivers of community gun violence.

RESUMO

BACKGROUND: Many countries and communities in sub-Saharan Africa suffer from inadequate access to healthcare and healthy lifestyles as reflected in their high mortality and morbidity rates. Large-scale interventions like the medical city project presented in this article are necessary to address the significant health burdens faced by populations in this region. OBJECTIVES: This article shows how evidence-based approaches and multisectoral partnerships guided the development of the 327-acre Medical City master plan in Akwa Ibom, Nigeria. This is envisioned to be the first-of-its-kind medical city in this medically underserved "healthcare desert." METHODS: The five-phased, seven-year (2013-2020) master planning process was guided by the overarching design framework of "sustainable one health" along with its 11 objectives and 64 performance measures. The data/evidence used to guide the planning decision-making process came from case studies, literature reviews, stakeholder interviews, and on-site investigations. RESULTS: The outcome of this project is a comprehensive medical city master plan that includes a self-contained, mixed-use community anchored by a hospital and a primary healthcare village. This medical city provides access to the full range of healthcare services (e.g., curative-to-preventive, traditional-to-alternative) and is supported by multimodal transportation systems and extensive green infrastructure. CONCLUSIONS: This project offers theoretical and practical insights on "designing for health" in a frontier market while responding to the complex local contexts that present many unique challenges and opportunities. Those insights provide useful lessons for researchers and professionals interested in promoting health and healthcare services in healthcare deserts.

RESUMO

Consumers play an integral role in mediating ecological succession-the change in community composition over time. As consumer populations are facing rapid decline in ecosystems around the world, understanding of their ecological role is becoming increasingly urgent. Increased understanding of how changes in consumer populations may influence community variability across space and turnover through time during succession is particularly important for coral reefs, which are among the most threatened ecosystems globally, and where fishes play vital roles in structuring benthic succession. Here, we examine how consumers influence coral reef succession by deploying 180 paired settlement tiles, caged (to exclude fishes larger than approximately 15 cm) and uncaged, within Palmyra Atoll, a remote marine wildlife refuge with previously documented high fish abundance, and monitored benthic community development one and three years after deployment. We found that excluding large fishes lead to lower alpha diversity and divergent community states across space (i.e.,, high beta diversity among caged tiles), suggesting that benthic fish feeding maintains local diversity but tends to homogenize community composition with dominance by crustose coralline algae. In addition, when fish were experimentally excluded, the developing benthic community exhibited a greater change in species composition over time (i.e., high temporal beta diversity), indicating that fish feeding tends to canalize community successional trajectories. Finally, the caged and uncaged tiles became more similar over time, suggesting that fish feeding plays a more important role during early succession. Our results demonstrate that the loss of large fishes, for example from overfishing, may result in benthic communities that are more variable across space and time. Increased variability could have important implications for ecosystem function and coral reef resilience in the face of escalating global stressors.

RESUMO

Objective Mutsuzawa town, Chiba Prefecture, relocated a "health-supportive" roadside station in 2019. The underlying hypothesis is that older people who use the roadside station will have better self-rated health than those who do not use it. We aimed to verify whether roadside station use was associated with a decrease in poor self-rated health.Method This was a longitudinal study that compared and evaluated the roadside station use and non-use groups using three-wave panel data before and after relocation of the roadside station in September 2019. To obtain three-wave panel data, self-administered questionnaires were mailed three times: in July 2018 (FY 2018) before the station was relocated and in November 2020 (FY 2020) and January 2022 (FY 2021) after the relocation in 2019. The dependent variable was poor self-rated health in FY 2021, and the independent variable was use of the roadside station as of FY 2020. Covariates included basic characteristics from FY 2018, as well as going out, social participation, and interacting on social networks in FY 2018 and FY 2020. A multivariate analysis was conducted using multiple imputation to complete missing values for the Crude model, which included the basic attributes of FY 2018 (Model 1); going out, social participation, and interacting on social networks in FY 2018 (Model 2); and going out, social participation, and interacting on social networks in FY 2020 (Model 3). The cumulative incidence rate ratio (CIRR), 95% confidence intervals, and P-values were calculated using a modified Poisson regression analysis for each model.Results Of the 576 participants, 344 (59.8%) were roadside station users. The multivariate analysis adjusted for basic attributes revealed that the number of people with poor self-rated health in the user group was significantly lower than that in the non-user group, with a CIRR of 0.67 (95% confidence interval: 0.45-0.99, P=0.043). However, the adjusted model showed a CIRR of 0.71 (95% confidence interval: 0.48-1.06, P=0.096) for going out, social participation, and interacting on social networks in FY2020 after the roadside station opened.Conclusion Findings of this study revealed that, after adjusting for confounding factors prior to relocation of the roadside station, the number of people with poor self-rated health decreased in the user group. Thus, such commercial facilities as roadside stations, which give users an opportunity to go out and meet people, can provide a "naturally healthy" environment.

RESUMO

This paper reviews theories regarding online learning communities in higher education and their relevance to online degree programs. While these theories are used extensively to promote and maintain community within online courses, little attention has been placed on broader factors that can influence perceptions of online community. Based on our research as well as an extensive review of the literature, this paper articulates limitations in current research and posits a framework to look at institutional, program, and professional layers. The framework also considers community salience from these layers at various points in a learner's program. Based on the layers presented, the framework proposes that true communities are shaped by myriad partners and that these partnerships should not be ignored in community research. Furthermore, it admonishes educators to provide guidance to learners regarding the purposes of community formation both during and beyond program completion. Lastly, the paper articulates needs for further research as online degree programs consider community development and maintenance through more holistic approaches.
