From Rules to Prototypes

Summary

Traditional expert systems attempt to represent logically the complex decision rules used by experts. This approach has some defined successes but has been less effective with multi-dimensional problems such as characterize clinical situations. Research suggests that effective expertise is based more on memory than on analysis and logic. The article discusses the nature of memory-based expertise and questions the feasibility of capturing it through expert systems.

Training based on computerized case simulations is suggested as an alternative. The paper also discusses the need for knowledge on the specific impact interventions have on distinct subgroups of consumers. This knowledge can be used to guide training and assist consumers in making key decisions.     

Developing Expert Systems

Summary

This article provides an overview of the general procedure and steps involved in developing expert systems. The first consideration is to select a suitable problem. Actual development of the expert system begins with formulating and representing the knowledge base. Then a programming tool is selected for use in developing the expert system and a working prototype is developed. After a period of evaluation and reformulation the full expert system is completed. Finally, the performance of the expert system is formally evaluated, final modifications are made, and the expert system is put into everyday use. Additional resources are provided for further reference.     

Expert Systems

Summary

Expert systems are computer programs which embody the expertise of a human expert in order to consult and advise on a specific problem. It is now becoming feasible to apply expert systems technology to problems in the human services. This article describes what expert systems technology is and how it may be applied in human service practice. Finally, some of the promises and pitfalls of this new technology are addressed.     

The Corporate University and social work academic roles

Abstract

Universities have undergone significant changes in the last decade. Universities have become ‘corporate’, integrating the values, assumptions and ethics of corporate economic capitalism. Within universities, social work practice expertise is negated as a criterion of valued ‘technological role expertise’ of social work academics. The paper describes and analyses the compounding impact of changes in the role of universities upon the historically problematic relationship between social work practice and social work education, The paper suggests a means to integrate both roles in the roles of practitioner-academic and academic-practitioner A typology is developed which identifies the knowledge and skill basis of social work practitioners and academics. The typology enables an identification of the cross fertilisation of each role on the practice expertise of the other. Through such a typology an alternative valued criterion of ‘technological role expertise’ can be established by the profession itself for utilisation in both academic and practice appointments and promotion assessment.     

Systems Analysts Are Perilous for Social Welfare Organizations

Summary

The computer is a necessary instrument for social work. When agencies computerize they usually do so without much hardware or software knowledge. So, in the best American tradition, they turn to an expert, the systems analyst. And, equally, in the American tradition, this expert offers an ideal solution. The only thing wrong with this perfect scenario is that the solutions seldom meet user needs. This paper examines this situation and suggests ways for agencies to avoid getting more systems analysis than they need. And it offers suggestions for creatively implementing the necessary switch to computer technology.     

Unemployment in the Czech Republic and Development of an Expert System for Assessing Unemployment Compensation

ABSTRACT

This paper addresses contemporary problems of unemployment in the Czech Republic (finding optimal alternatives of organizational structures of services of employment agencies). Based on characteristics and knowledge of information flows of the decision making process of claimants of unemployment compensation, a prototype expert system was developed to support this decision making. Results-of this research were evaluated from two points of view-the theoretical and practical benefits.     

Young People Leaving Care: Participatory Research to Improve Child Welfare Practices and the Rights of Children and Young People

Abstract

This paper discusses participatory research with young people who are leaving public care in Finland to begin independent lives. The aim of the research, organised by SOS Children's Villages International, was to bring about change in alternative care arrangements, particularly those involving young people's transition to independence. The project used a participatory research design based on employing care-leaving peers as co-researchers. This paper adheres to the methodological principles of empowerment in analysing the personal experiences of young people leaving alternative care with the goal of informing good practice. The findings suggest that the peer research method can be an effective means of empowering young people to develop research skills and to be involved in knowledge production, as well as serving as a means of promoting improved services for “care-leavers”, those young people who are leaving either foster care or institutional care. The participatory and peer research method challenges the traditional understandings of expertise and knowledge production. Although the hierarchy between adult researchers and young people as co-researchers is still evident, the method provides possibilities for better understanding the social- and health-service systems and their challenges and pitfalls from a user's perspective.     

Challenges in mentoring at-risk young adults: caseworkers’ perspective

ABSTRACT

This exploratory study examines the barriers, challenges and needs of 30 caseworkers who mentor at-risk young adults during the transition to adulthood. Professional mentoring relationships are an important source of support for at-risk young people. However, literature concerning the mentoring relationship from the perspective of the mentors is scarce. The theoretical thematic analysis revealed two major themes. The first theme- included challenges related to the young adults’ personal histories and characteristics. The second major theme related to the mentors’ expertise within their own services. The most dominant needs during the mentoring process were broad and current knowledge and ongoing training and support. The findings are discussed in relation to the mentoring literature and emerging adulthood theory. Implications for practice highlight the importance of the design and assimilation of programs that enable the promotion of meaningful mentoring relationships via organisational modifications.     

Improving student knowledge and perceptions of primary care providers at campus health centers

ABSTRACT

Objective: To examine current knowledge and perceptions toward primary care providers commonly staffed at student health centers (PAs and NPs), and also assess the effectiveness of information-rich provider biographies to improve knowledge and perceptions. Participants: One thousand six hundred forty six students from 2 universities in 2 states participated in this study from February to November, 2016. Methods: An online survey. Students were exposed to an improved biography of an NP discussing how she can perform many of the same duties as primary care physicians. Changes in knowledge and perceptions were assessed pre- and post-biography exposure. Results: More than half of students are unaware NPs and PAs can prescribe medications and diagnose illnesses. Students exposed to the biography increased their knowledge of NPs, and perceptions of their expertise. Conclusions: Results suggest improved provider biographies on student health centers' websites can help reduce the knowledge deficit that exists among students regarding common primary care providers.     

The Role of Theory in the Assessment of Sex Offenders

SUMMARY

No generally accepted theory of sex offender behavior exists at this point. As clinical experience and research findings interact within an evolving theoretical framework, the picture of what is important, as well as what is possible to know about a sex offender, is rapidly changing. It is vital that mental health professionals, the legal system, social service agencies, and other consumers and providers of sex offender assessments be aware of both what is possible to learn about an offender as well as the limitations on that knowledge and its application. Prominent theories that influence the assessment of offenders in North America and Europe are presented and examined. Uses and limitations of each theory are discussed. Several trends emerge which could influence the future of sex offender assessment, treatment, management, and policy.     

Doing It Well

SUMMARY

Social workers are being challenged internationally to be accountable by defining competency standards at beginning and advanced levels. The study that is the subject of this article will develop the work of one of the authors, which involved a 5-year longitudinal study of beginning social workers and another of experienced social workers. These studies resulted in a book on professional expertise (Fook, Ryan, & Hawkins, 2000). The present study furthered that work and subjected this theory of professional expertise to further testing by examining the work of a sample of expert (rather than experienced) social workers in the mental health field in Melbourne, Australia. Data was collected from a selected sample of mental health social workers by the use of focus group interview. This article reports on the study's findings and discusses their significance and application.     

Using Case-Based Reasoning to Develop Computerized Guidance for Effective Practice

SUMMARY

Research on expertise suggests that several years of extensive practice should lead to the development of good insights into effective practice. This paper describes this research and what it suggests about ways to capture and utilize such expertise in a computerized training simulator. Case-based reasoning is looked at as a way to interpret this research and its utilization. The paper also summarizes a project that is collecting such experience-based insights in the child welfare field. Particular attention is directed at ways to validate the experiential insights collected.     

Cross-disciplinary Collaboration and Health Promotion in Schools

Abstract

School-based social workers, collaborating with teachers, can contribute to the development of the skills, knowledge, and attitudes required for individuals to live healthy lives both in the short and long term. This article reports on a case study that investigated the effectiveness of the input of social work into a school-based health promotion model. Results indicated that cross-disciplinary collaboration was dependent on a number of factors: commitment to the value of cross-disciplinary collaboration, the clear identification and articulation of the expert skills and knowledge that each discipline brings to the collaboration, and on the effective negotiation of the contribution of each discipline's expert skills and knowledge to the collaboration. When these factors are embedded in a school's formal and professional arrangements, then cross-disciplinary collaboration is more effective. This research provides theoretical and practical lessons for those embarking on cross-disciplinary collaborations in the school setting.     

A Partnership Model for Family Service Agencies and Universities to Improve Service Utilization

ABSTRACT

Partnerships between family service agencies and universities have the potential for capitalizing on the resources and expertise of both types of institutions. This paper describes a model for developing collaborative partnerships between family service agencies and outreach research university programs. The original collaboration that is used as an example for this model sought to improve the engagement rates of reluctant families being referred to a family service agency for counseling services. Benefits and potential pitfalls to be addressed in such partnerships are presented.     

Exploring the relationships among practitioners’ consultation skills,competence to counsel lesbian,gay, and bisexual clients,and attitudes toward transgender people

Abstract

Consultation is an intervention that can diffuse expertise in lesbian, gay, bisexual, transgender, and questioning (LGBTQ) issues throughout systems of care. Practitioners (N?=?145) were surveyed on their lesbian, gay, and bisexual (LGB) counseling competence, attitudes toward transgender people, and consultation skills. Hierarchical multiple regression analysis identified that consultation competence significantly influenced (p?≤?.01) LGB counseling skills over and above LGB knowledge and awareness, attitudes toward transgender people, and participant demographic characteristics. The domains of LGB competence and attitudes toward transgender people were also significantly correlated within the participant sample. Implications for practice, training, and future research are discussed.     

Medical Uncertainty in Students Entering Medical School

Abstract

Uncertainty is a fundamental characteristic of medical practice. Renee Fox described three types of uncertainty: limitations in the body of medical knowledge, incomplete mastery of existing knowledge, and distinguishing between limitations and mastery of knowledge. This investigation administered ten Likert-format questions about uncertainty to 171 incoming medical students at one state medical school Items were reliable over a six week test-retest, and validity was supported by correlations with an Intolerance of Ambiguity scale. Entering students recognized that uncertainty exists in medical knowledge and mastery of medical knowledge. Factor analysis of the ten item uncertainty scale revealed three dimensions: uncertainty of the profession, practice certainty, and growth in uncertainty. No significant differences in the uncertainty items, scale, or factors existed by demographic characteristics or medical specialty preferences. These findings suggest that students are aware of issues surrounding uncertainty in medicine as they begin medical school, but medical uncertainty at this early stage in medical socialization is not sufficiently powerful to be associated with medical specialty preference.     

Living on the edge? Professional anxieties at work in academia and veterinary practice

ABSTRACT

Through empirical research on academics and veterinary surgeons, this article focuses on identity and how it is reflected in, and reproduced by, anxiety and insecurity at work. Three analytical themes – perfection, performativity and commodified service – each of which generates anxiety indicates a loss of autonomy as academics and vets are subjected to competitive market forces as well as an intensification of masculine managerial controls of assessment, audit and accountability. We see these pressures and their effects as reflecting a commodification of service provision where the consumer (student or client) begins to redefine the relationship between those offering some expertise and those who are its recipients, partly achieved through the performative gaze of constant and visible rating mechanisms. Our empirical research also identifies sources of anxiety concerns in their attempts to achieve perfection against this background of uncertain knowledge and precarious contexts of the performative nature of professional expertise.     

The Responsible Use of Psychological Testing in Child Custody Evaluations: Selection of Tests

SUMMARY

The responsible use of psychological tests in child custody evaluations requires an advanced understanding of both psychological issues of test selection and legal criteria regarding admissibility of expert testimony. This paper discusses the psychological and legal issues associated with test selection and with admissibility of expert testimony pertaining to psychological test data. It is argued that the legal standards of relevance and helpfulness require the methodology underlying an expert's testimony to be both reliable and valid. Therefore, it is essential to select psychological tests with demonstrated reliability and validity. Case law regarding expert testimony and the integration of professional practice guidelines pertaining to the use of psychological tests with ethical standards will be discussed.     

Evaluation of a Web-Based Malaria Risk Reduction Game for Study Abroad Students

Abstract

Objective: Compare feedback strategies in 3 versions of an educational game. Participants: Study abroad students (N = 482) participated by playing the game and completing pregame/postgame surveys January–March 2010. Methods: This study employed an experimental design. Primary outcome measures were knowledge gain, player satisfaction, and risk perception. Results: One-third had previously traveled to a malaria-risk region, and two thirds planned to do so. Baseline malaria knowledge was low. Postgame knowledge and risk perception were significantly higher than pregame, irrespective of past travel status. The group that automatically received explanatory feedback following game decisions scored higher for mean knowledge gain, without differences in player satisfaction. Conclusions: The challenges of designing a feedback strategy to support Web-based learning make these results highly relevant to health educators developing interactive multimedia interventions. The increasing number of students traveling to higher-risk destinations demands attention. Both malaria-naive and malaria-experienced students would benefit from this approach to travel health education.

‘Making narrative portraits: a methodological approach to analysing qualitative data’

ABSTRACT

This paper proposes the method of ‘narrative portraiture’, which, located within the wider field of narrative studies, offers an analytical tool to narrative data. Two research projects, one on disability and one on identity, are used to illustrate how the method can be applied. While the paper will focus on the methodological benefits and limitations of the approach, throughout the article we also highlight the ethical concern of representation. We suggest that through ‘narrative portraiture’ research findings can be contextualised in broader social narratives without losing sight of the unique personal qualities of the research encounter. Thus, we argue for the importance of bringing the participant and their everyday life experience into focus, highlighting that a portrayal of a sole story can be, not only a medium to understand a research phenomenon, but also a valuable research output in itself.
