Fuzzy duocentric community detection model in social networks

The main goal of this paper is to present a clustering model to identify duocentric communities in the complex networks. A duocentric community is built around two central nodes which are as close as possible to other nodes, while the central nodes are connected enough to each other to shape the center of the community. To detect such communities, we develop a new objective function based clustering model. The network's nodes are assigned to the duocentric communities by the type-2 fuzzy numbers which indicate the degrees of belonging to the communities by upper and lower membership values. Generated interval type-2 fuzzy membership values by our proposed model are able to determine how much each node belongs to the both central nodes and how it is shared among communities. Also, the compatible verification index with the proposed model is introduced to evaluate and compare the results of the proposed model with the existing approach in the literature. Finally, the performance of the proposed algorithm is validated by detecting duocentric communities in three artificial networks and two real social networks.     

To die destitute today: What are the implications for social work?

The link between the public hospital and the destitute funeral has a long historical background with hospitals today continuing to retain their delegation over the fates of those who die destitute within them. This qualitative study evaluates the roles and skills of social workers when assessing the need for a destitute funeral in the public hospital system. Social workers located in two public hospitals within the same Area Health Service participated in interviews to evaluate the roles and responsibilities of social workers when working with destitute funeral recipients and their significant others. Emergent from these interviews are the social workers' candid perception of the importance of the destitute death. The analysis is structured according to the priority that the social workers themselves accorded: the importance of the destitute death to the organisation, the family and friends of the destitute person, the social workers themselves and to society as a whole. The implication for social work practice is that this study informs policy locally within the hospital social work department, and public health policy within the hospital system. In addition, it is a springboard for practice reflection and advanced clinical practice by social workers in the field of destitute funerals.     

Applications of Machine Learning Methods to Predict Readmission and Length-of-Stay for Homeless Families: The Case of Win Shelters in New York City

ABSTRACT

New York City faces the challenge of an ever-increasing homeless population with almost 60,000 people currently living in city shelters. In 2015, approximately 25% of families stayed longer than nine months in a shelter, and 17% of families with children that exited a homeless shelter returned to the shelter system within 30 days of leaving. This suggests that “long-term” shelter residents and those that re-enter shelters contribute significantly to the rise of the homeless population living in city shelters and indicate systemic challenges to finding adequate permanent housing. This article focuses on our preliminary work with Win (Women-in-Need) shelters to understand the factors that predict readmission and length-of-stay of homeless families. We create a unified, comprehensive database of the homeless population being served by Win shelters, accounting for more than 6,000 homeless families. We apply logistic regression models and an unsupervised clustering algorithm to identify predictors of re-entry and long-term length-of-stay. Citizenship, age, medical conditions, employment, and history of foster care or shelter stays as a child are found to be significant predictors. The results of the K-means clustering identify three primary groups, consistent with previous typologies characterized by transitionally homeless, episodically homeless, and chronically homeless.     

Single Session Social Work in Hospitals

This paper reports on three complementary research studies that set out to examine the incidence and nature of single sessions in hospital social work practice. The first study was a data‐mining exercise that used statistics recorded by practitioners in nine public hospitals over a 12‐month period to establish the extent of single session work, the clinical areas in which it occurred, and the types of issues it covered. This quantitative information was enhanced with the qualitative findings of the two subsequent studies: the first with hospital social workers; and the second with singlesession clients. We concluded that single session work has not been sufficiently acknowledged in social work education and literature, and that it needs to become a more legitimate part of social work practice and training. At best, it represents social work at its highest level of skill, requiring expertise in quickly building rapport, assessment, and knowledge about sources of practical aid and information.

Abstract

Bone marrow transplantation (BMT) has been under-studied from a social work perspective. This article reports on a cross-institutional study into the psychological and social preparation for bone marrow transplantation. The data presented was collected from all consenting BMT recipients treated over a preceding three year period at four teaching hospitals. The key findings included demographic issues which had an influence on post transplant adjustment, lack of rehabilitation services, ongoing physical incapacity, disappointment at the slow rate of recovery, lack of counselling resources, difficulties in the way information was presented, difficulties with the transition from hospital to home and a perceived lack of interest by hospital staff of the needs of carers. These results were presented to the social workers in each BMT unit. They considered the extent to which the findings matched their clinical experience, and the relevance of the research to their social work practice. This discussion suggested the need for social work involvement on a number of levels beyond case-work, particularly in promoting organisational change.     

Fast clustering for signed graphs based on random walk gap

Signed graphs are often used as models for social media mining, social networks analysis and nature language processing. In this paper, we study clustering algorithms for signed graphs that can be scaled for use in large-scale signed networks. A proposed mechanism, called a random walk gap (RWG), is used to extract more cluster structure information. RWG uses two types of random walks on signed graphs. The first considers positive edges only. The second takes negative edges into account. Three types of edges in signed graphs are identified and their different characteristics in terms of transition probability changes are determined for the two types of random walk graphs. Different characteristics contain different information about cluster structure and a RWG matrix is used to reflect the differences. The RWG matrix is used to adjust the weights of edges in signed graphs. This is the first study to perform a random walk on negative edges. A fast clustering for signed graphs (FCSG) algorithm is then proposed. This FCSG is compared with existing methods. The computational times for different algorithms are measured. The experiments show that the proposed FCSG algorithm gives better results than existing algorithms based on the performance criteria of imbalance and modularity.     

Teaching Successful Community Practice in Social Work

ABSTRACT

This article identifies and addresses a severe problem in the management of community practice projects of students in their second and third year in the Undergraduate Social Work program at the University of Haifa School of Social Work; namely, the current binary evaluation method based on total success or failure of the project.

Using a systems approach, this study creates a framework by which to ensure effective and positive outcomes for community practice projects carried out by undergraduate social work students (Freund, Arkin & Saltman, 1999). This framework is unique in that it draws on knowledge gained from organizational and community theories, as well as instructional theories for teaching social work practice.

The proposed framework includes three components that describe the factors necessary to help transform the student's learning experience: the organization's characteristics, the student's resources, and the evaluative measures.

This inter-conceptual approach enhances the ability of the instructor, the student, and the organization to build an appropriate organizational foundation for students operating communal programs. The underlying assumption is that an integrative approach promotes a better understanding of the components essential for building and evaluating social plans conducted by social work students.     

Evaluations of Social Work Education: A Critical Review

Since the introduction in England of the social work degree in 2002, there have been a number of significant changes to social work education culminating with the implementation of the Social Work Reform Board's innovations in 2013. This article critically explores the role of evaluations of changes in social work education and their implications for social work pedagogy. Evaluations can be linked to wider trends in society such as modernity, reflexive modernity, and the audit society. These wider influences affect the use of evaluations. A way forward for social work is proposed. Social work education needs to develop a critical pedagogy of hope to transform the profession's relationship not only to evaluations but to practise as well. The key message of this article is that evaluation studies of social work education mirror the underlying tensions of late modernity. Therefore, social work education needs to adopt a critical pedagogic approach to the use of evaluation research.     

Social Work in the Emergency Department—Implementation of a Domestic and Family Violence Screening Program

Abstract

Women who have experienced domestic and family violence use health services more frequently than women who have not. Early identification and intervention by the health system may reduce health problems associated with domestic and family violence and lead to savings for the health sector. This study aimed to evaluate the impact of a new domestic and family violence screening program, which was based on an ecological model and introduced by a social work team in the Emergency Department of a major metropolitan hospital. The evaluation method included an audit of social work case files to assess the effect on referral rates and a survey of Emergency Department staff to obtain perceptions of the impact of the program on the staff and clients. In the 3-month period following the introduction of the program, the rate of referral to social work increased by 213%. Staff agreed that the Emergency Department is an appropriate place to ask about domestic and family violence, under certain conditions. Findings suggest that an ecological social work model provides an approach to screening for domestic and family violence that not only contributes to increased identification and supportive client interventions but may also contribute to more sustainable systemic change.     

Expanding the Postpartum Depression Construct Using a Social Work Paradigm

This paper describes and evaluates current definitions and models of postpartum depression. Research on prevalence, risk and resiliency factors is reviewed. A more comprehensive approach to postpartum mood disorders is proposed. The “Model Assessing Maternal Adjustment” (MAMA) is based on the biopsychosocial approach of social work and can be utilized for both client self-assessment and clinical assessments by professionals across various disciplines. The MAMA approach moves beyond sole focus on depressive symptoms to include anxiety symptoms and bipolar disorders and lengthens the time frame to include the pregnancy through the first year postpartum.     

An evaluation paradox in social work? An empirical study of evaluation use in connection with temporary programmes in Swedish social work

This article contributes to the debate on evaluation use by analysing temporary national programmes in Swedish social work. Previous empirical research shows a gloomy picture of evaluation use, thus supporting an evaluation paradox: evaluations are not used for learning and development, but are continually prioritised. The aim of this article is to study, through interviews and document analysis, how evaluations of temporary programmes in social work are designed and used. The results support the paradox and we found that it has two dimensions. First, evaluations are prioritised, but they function as a ritual, characterised by routine and unclear intentions, with limited relevance for professional learning and improvement. The second dimension is about limited use by those commissioning the evaluations, but the evaluators are using data for new purposes and in new contexts. This is, at best, a form of conceptual use, hopefully contributing indirectly to social work practice. The article ends in a discussion on how evaluations could be designed for learning and improvement by focusing on three normative models: utilisation-focused evaluation, responsive evaluation and evidence-based practice approach (EBP).     

Addressing Psychosocial Barriers to Hospital Discharge: A Social Work Led Model of Care

Australian hospitals regularly care for patients who cannot be discharged routinely due to complex psychosocial needs that manifest as barriers to discharge. These long-stay or “stranded” patients are at risk of detrimental health outcomes resulting from their extended stay while also potentially delaying admission for those who need acute care. This article discusses a new social work led model of care developed at an Australian metropolitan hospital that targets long-stay patients with psychosocial barriers to discharge. The model of care, overseen by a specialist social worker and assistant, demonstrates how the social work profession can take leadership within the psychosocial realm to improve both organisational and patient outcomes.     

Farmers' Contribution to Agricultural Social Capital: Evidence from Southern Spain

Social capital is the whole set of shared norms, values, attitudes, and beliefs that promote cooperation among individuals within the community and that has proved to be a key factor in explaining development processes. This article aims to provide an analytically reliable notion of social capital within the farming sector and a methodological tool for empirically measuring how social capital is accumulated at the farmer level. The theoretical framework proposed is based on the multidimensionality of the complex concept of social capital. Thus, to develop a comprehensive index for social capital, we identify three dimensions of the concept, structural, relational, and cognitive social capital, each one also comprising several subdimensions. This integrative approach permits creation of a composite indicator of the agricultural social capital accumulated at the farmer level, further identifying socioeconomic factors that influence its accumulation at that level. We empirically apply this methodological approach to farmers in Andalusia in southern Spain as a case study. This research provides an interesting starting point for informing policymakers about social capital and helping them implement the necessary programs to facilitate sustainable development in the agricultural sector.     

Evidence-Based Social Work Practice with Mentally Ill Persons who Abuse Alcohol and Other Drugs

Abstract

The current article outlines a comprehensive approach to evidence-based social work practice, and applies it to persons with severe and persistent mental illness who also abuse alcohol and other drugs. Representative empirical literature is summarized within a framework that delineates the three major functions of evidence-based social work practice: assessment, intervention and evaluation. Assessment protocol, which incorporates the use of valid scales to complement the qualitative interview, is based on domain-specific research that outlines relevant psychosocial risk factors, and highlights those that are amenable to change. Intervention strategies are derived from the growing body of controlled research findings, but flexibility in implementation is recommended to accommodate clients' individual needs and the vagaries of daily practice. Naturalistic evaluation methods are used to capitalize on the use of brief, valid process and outcome measures to augment individual qualitative evaluation and to aggregate data for program evaluation. The implications of this integrated evidence-based strategy for social work practice are discussed.     

The reform of the welfare services in Norway: one office – one way of thinking?

This paper discusses the professional role of social workers in the new Norwegian Nav system. The Nav reform merged the state social insurance office, the state employment office and components of municipal social services. The aim is to include clients in the work force by making the services more holistic and efficient. The paper presents a discussion of the introduction of the ‘Nav reform’, drawing on a qualitative multi-method study. The material sheds light on a social worker's role under pressure to work in a more standardised and ‘simplified’ way. Social workers at the Nav offices must adjust to expectations that require a general, basic and common competence for all employees, as one type of comprehensive, but simplified and non-specialised, approach. The study describes the dilemma of how to combine one-stop service and specialist principles. The paper attempts to criticise ‘the flexible system’ related to Whole of Government perspectives and one-stop service principles as a generalist ‘light’ approach, as opposed to the generalist approach in social work. The findings provide a basis for raising questions about the development of the social worker's role in light of the post-New Public Management (NPM) reforms and the potential threat to the professional basis of social work.     

A multidimensional approach to child poverty in Taiwan

To elucidate the multidimensional nature of poverty, this study analyzed child deprivation and social exclusion in Taiwan. First, a fuzzy set approach was used to construct an aggregate poverty index, to measure the levels of perceived necessity, deprivation, and social exclusion experienced by children. The study involved conducting a decomposition analysis to measure the poverty index according to certain dimensions. Second, this study involved analyzing possible determinants of perceived necessity, deprivation, and social exclusion, using seemingly unrelated regression models. We used cross-sectional data obtained from the Household Living Conditions Survey conducted in 2014. The results suggest that over two-thirds of the respondents identified all the items as necessary. Three highest levels of perceived necessity were housing, medical care, and clothing dimensions. Children faced high risks of deprivation and exclusion. The three highest levels of deprivation and exclusion were exhibited in the dimensions of environment, recreation, and education; the lowest two levels of deprivation and exclusion were exhibited in the dimensions of medical care and housing. The dimensions with higher levels of deprivation and exclusion exhibited higher relative contributions to facilitating poverty reduction. Moreover, evaluation of income and expenditure, family income, and family type were significantly related to the degree of perceived necessity and the levels of deprivation and exclusion. Those living in families with a large number of children exhibited a higher level of deprivation. Education of the caregivers was closely linked to social exclusion of children. This paper represents preliminary and small-scale research; however, several implications for methodology and policy can be derived from this study.     

Preparing for Practice: An Evaluation of an Undergraduate Social Work ‘Preparation for Practice’ Module

The requirement for social work students to undergo assessed preparation prior to undertaking their first practice placement raises key questions about the type of knowledge and experience that is needed for those at the start of their training. This paper shows the need for social work educators to become re‐engaged in debates about the practice–theory relationship and to explore what is meant by an incremental approach to learning. A Preparation for Practice Learning module which was delivered to a cohort of Level 1 undergraduate social work students at a London university is described and evaluated. The paper highlights the key themes which emerged from the evaluation; these include the importance of work shadowing, observational learning and the centrality of critical reflection in aiding students' personal and professional learning. A discussion of its effectiveness in preparing students for their first practice learning experience follows. It concludes by recommending how students' learning in relation to the nature of social work and the skills required to undertake the role effectively might be addressed within the curriculum. Finally, a Preparation for Practice Learning model based on these findings is proposed.     

Exploring the Potential of Social Network Analysis in Asset-based Community Development Practice and Research

Abstract

Strengths-based practice appears to be a popular approach to social work practice. Increasingly, it has become the approach of choice in community work, with the “asset-based community development” model being utilised both in Australia and internationally. However, asset-based community development has been criticised for its lack of an evidence base, lack of theoretical depth, and its lack of consideration of the macro level causes of disempowerment. While concepts of networks are central to asset-based community development, social network theory and analysis have rarely been utilised in a comprehensive manner in asset-based community development practice or research. This article contends that asset-based community development practice can benefit from the integration of key concepts from social network theory. Similarly, it is proposed that social network analysis holds promise as an appropriate methodology in terms of understanding the efficacy of asset-based community development projects.     

Graduate Social Work Students’ Approaches and Ways of Thinking in Child Protection Assessment: Case Vignette Reflections from Estonia

This article examines Estonian graduate social work students’ (MSW, n = 41) assessment approaches (deficit-based versus strengths-based) in the context of a child protection assessment through a case vignette format. The study found that students tend to focus more on a traditional deficit-based approach in their responses to a presented case, and less on capabilities and resources. The study indicates the need to find ways to promote more client-friendly approaches (for a shift in the way of thinking) in social work education to empower families through developing a respectful and effective helping relationship that promotes comprehensive assessment guided by social work values. Practice implications are discussed and recommendations for future research are outlined.     

The Association of Alternative Financial Services Usage and Financial Access: Evidence from the National Financial Capability Study

This study examined the association of financial access and alternative financial services (AFS) using a nationally representative sample from the 2012 National Financial Capability Study (N = 25,509). Structural equation modeling was used to examine the relationship between financial access and AFS usage. Ordinary least squares regression was used to estimate the relationship between banked status and the overall AFS usage as a latent variable while controlling for sociodemographic variables, financial education, financial knowledge, and home ownership. Results suggested that being unbanked was positively associated with AFS usage after controlling for other covariates. Financial education and knowledge, age, gender, marital status, education, household income, and homeownership were significantly associated with AFS usage. These findings have implications for public policy and programs that work with the unbanked.
