Community structure is considered one of the most interesting features in complex networks. Many real-world complex systems exhibit community structure, where individuals with similar properties form a community. The identification of communities in a network is important for understanding the structure of said network, in a specific perspective. Thus, community detection in complex networks gained immense interest over the last decade. A lot of community detection methods were proposed, and one of them is the label propagation algorithm (LPA). The simplicity and time efficiency of the LPA make it a popular community detection method. However, the LPA suffers from instability detection due to randomness that is induced in the algorithm. The focus of this paper is to improve the stability and accuracy of the LPA, while retaining its simplicity. Our proposed algorithm will first detect the main communities in a network by using the number of mutual neighbouring nodes. Subsequently, nodes are added into communities by using a constrained LPA. Those constraints are then gradually relaxed until all nodes are assigned into groups. In order to refine the quality of the detected communities, nodes in communities can be switched to another community or removed from their current communities at various stages of the algorithm. We evaluated our algorithm on three types of benchmark networks, namely the Lancichinetti-Fortunato-Radicchi (LFR), Relaxed Caveman (RC) and Girvan-Newman (GN) benchmarks. We also apply the present algorithm to some real-world networks of various sizes. The current results show some promising potential, of the proposed algorithm, in terms of detecting communities accurately. Furthermore, our constrained LPA has a robustness and stability that are significantly better than the simple LPA as it is able to yield deterministic results.
Safe Communities, representing a global activation of the public health logic, may be strengthened through theoretical, methodological and empirical support. In the spirit of this Special Issue that aims to analyse the achievements and challenges inherent to Safe Communities, we offer our contribution in the form of a methodology of a multi-country child safety, peace and health promotion study. The study, situated within an African-centred initiative called Ukuphepha - an isiZulu word meaning demonstrating African safety - is underpinned by four theoretical claims that frame injury and violence prevention as a multi-disciplinary issue to be addressed through a suite of interventions to family and extended social systems. The interventions, sensitive to the priorities of each participating country, have been informed by the literature on effective interventions and the authors' joint experiences of community development. The study is designed as a population-based, multi-level, multi-intervention partly randomised controlled trial, and there are potentially 24 participant communities representing South Africa, Mozambique, Egypt, Zambia, Uganda, Bangladesh, Malaysia and Australia - over three commencement phases. Whereas process evaluation will focus on community engagement, impact evaluation will consider risk and protective factors, and outcome evaluation will examine the overall effectiveness of the interventions. Notwithstanding the many challenges, the study will provide insights into the methodology and mechanisms of ecologically-oriented interventions that locate injury and violence prevention as an activity arising from safety, peace and health promotion.
Youth–adult partnership (Y–AP) has emerged as a key practice for enacting two features of effective developmental settings: supportive adult relationships and support for efficacy and mattering. Previous studies have shown that when youth, supported by adults, actively participate in organizational and community decision making they are likely to show greater confidence and agency, empowerment and critical consciousness, and community connections. Most of the extant research on Y–AP is limited to qualitative studies and the identification of organizational best practices. Almost all research focuses on Western sociocultural settings. To address these gaps, 299 youth, age 15 to 24, were sampled from established afterschool and community programs in Malaysia to explore the contribution of Y–AP (operationalized as having two components: youth voice in decision-making and supportive adult relationships) to empowerment, agency and community connections. As hypothesized, hierarchical regressions indicated that program quality (Y–AP, safe environment and program engagement) contributed to agency, empowerment and community connections beyond the contribution of family, school and religion. Additionally, the Y–AP measures contributed substantially more variance than the other measures of program quality on each outcome. Interaction effects indicated differences by age for empowerment and agency but not for community connections. The primary findings in this inquiry replicate those found in previous interview and observational-oriented studies. The data suggests fertile ground for future research while demonstrating that Y–AP may be an effective practice for positive youth development outside of Western settings.
The district of Kudat has one of the highest and most persistent malaria transmission levels in Sabah, Malaysia, with annual parasite incidence of 102 per 1,000 inhabitants per year. Due to this situation and the failure of DDT spraying to control malaria, a community participation health program (Sukarelawan Penjagaan Kesihatan Primer or SPKP) was developed as an adjunct to current anti-malarial measures during 1987-1991. SPKP is made up of unpaid community workers known as village health volunteers (VHVs). VHVs are selected by a village development and security committees training and supervision a member of the Vector-Borne Diseases Control Program (VBDCP). The beneficiaries of SPKP consisted primarily of Runggus people and other remote, and mobile populations who visit the home of a VHV for diagnosis and treatment. This group of febrile patients and their children who attend a participating school submit finger prick blood and personal details to the VHV. and receive a presumptive treatment for malaria. Thick and thin blood smears are examined by a VBDCP microscopist who then prepare and forward a radical or curative treatment to the VHV so that it can be administered to the microscopically-positive patient free of charge. Between June 1987 to June 1991, VHVs from 32 kampungs (villages) and 22 schools collected 56,245 slides representing 24.7% of total slide collection compared to 74.9% collected by passive case detection (PCD) posts in health centers and district hospital. The average volunteer treated 11.8 (range 10.4-13.4) and 31.4 (range 26-49) patients per month in kampungs and schools respectively. In contrast, non-SPKP posts in a district hospital, health centers and flying doctor service treated an average of 616.3 patients per month (range 134.8-1032.8). The slide positivity rate of blood smears taken by VHVs was 8.43% compared with 7.37% for non-SPKP posts. Average slide collection and slide positivity rates varied considerably from one community to another, despite their close geographic proximity. The monthly number of VHV-diagnosed patients from the school and kampungs communities and the monthly number of true malaria patients in the two groups were significantly correlated. Sustainability of SPKP was linked to an ongoing process of social change which involved co-operative networking between the government health sector and the community. This in turn provided a stimulus for malaria abatement efforts. When Runggus people themselves control and maintain ownership of community-based malaria programs, the function of SPKP as a malaria surveillance system and an antimalarial drug distribution network is vastly improved.

Summary: Alcohol is the number three contributor to the burden of disease worldwide so must remain a priority health promotion issue internationally. Malaysia is a Muslim country and alcohol-related harm was not seen as a priority until recently, because it only affects a minority of the population. Sabah has more than 30 different ethnic groups, and alcohol has a traditional role in the cultural practices of many of these groups. In 2009, the Intervention Group for Alcohol Misuse (IGAM) was formed, under the umbrella of Mercy Malaysia by a group of healthcare workers, academics, members of the Clergy and people who were previously alcohol-dependent concerned about the harmful effects of excessive alcohol consumption. IGAM in collaboration with other bodies have organized public seminars, visited villages and schools, encouraged the formation of a support group and trained healthcare professionals in health promotion intervention. The focus later changed to empowering communities to find solutions to alcohol-related harm in their community in a way which is sensitive to their culture. A standard tool-kit was developed using WHO materials as a guide. Village committees were formed and adapted the toolkit according to their needs. This strategy has been shown to be effective, in that 90% of the 20 committees formed are actively and successfully involved in health promotion to reduce alcohol-related harm in their communities.
Malay-Muslim men who have sex with men (MSM) are marginalized and hidden in Malaysia, a predominantly Muslim country in southeast Asia. We explored the policy, network, community, and individual factors related to HIV infection among Malay-Muslim MSM through 26 in-depth interviews and one focus group discussion (n = 5) conducted in Kuala Lumpur and Kota Bharu between October 2013 and January 2014. As religion plays an important role in their lives, participants viewed homosexuality as a sin. Low risk perception and misconceptions about HIV/AIDS were common, and most participants expressed reluctance to consult a doctor unless they had symptoms. Additionally, buying condoms was embarrassing and anxiety-producing. Fear of discrimination by health care providers and community hindered participants from disclosing sexual behaviors and accessing health services. Homophobic comments and policies by the government and religious leaders were concerns of participants. A safe and enabling environment is needed to reduce HIV risks among Malay-Muslim MSM.
PURPOSE: Patient self-management enables living with a chronic disease effectively. This study examines the effectiveness of a 4-week self-management programme to enable self-management of the numerous after-effects and with breast cancer as a chronic disease.
METHODS: Upon ethical approval, 147 multiethnic survivors (stages I-III breast cancer) received either a 4-week self-management intervention (n = 68) or usual care (n = 78) on a controlled clinical trial in a medical centre. The facilitator-led group intervention provides self-management support and skills for managing the medical, emotional and role tasks. Survivors completed the pre- and post-intervention measures on quality of life, distress and participation inventory.
RESULTS: Multiple analyses of covariance (adjusted for baseline measures) showed significant differences between groups [F(6, 129) = 2.26, p = 0.04 at post-test and F(6, 129) = 4.090, p
