Box 1346 Ann Arbor, Ml 48106-1346 ABSTRACT The thesis discusses the widely held view in social work that practice should be based on Intuitive and empathie understanding and that standard scientific procedures are inapplicable. I argue that this anti­ science attitude is misguided and that social workers can and should use scientific methods to test theories and develop more effective ways of helping. There are practical and philosophical reasons for re­ examining this dismissal of science. Social workers' statutory powers and duties have increased rapidly but there is also growing concern about their professional competence. Moreover developments in the philosophy of science challenge social workers' assumptions about science. The first two chapters discuss the importance of overcoming the hostility to science, examining social workers’ duties, training, and practice methods. The first objection to science examined is the claim that science studies only observable behaviour not mental phenomena. I argue that this is based on a false idea of science and suggest instead that there is great similarity in the way scientists and social workers theorise. The next chapter discusses the claim that the scientific search for causal explanations conflicts with a belief in free will; I argue that in fact there is no conflict. The following chapter questions the reliability and scope of fieldworkers* intuitive and empathie judgements and sets out some reasons why they should be supplemented with scientific methods of testing. What counts as empirical evidence and how theories are appraised are the topics of the next two chapters. I argue that the traditional social work view of empiricism is unduly narrow and has hampered social work research. I also address the comparatively new objection to science in social work, namely the relativists' claim that science is not empirical and therefore should not be held up as a model to social workers. The final chapter considers how scientific methods can be incorporated into practice.

Social workers are then involved in a series of difficult judgements and decisions. They must determine whether this is a case of child abuse, consider who might be responsible, speculate on the possible causes, assess the risk of further abuse, and decide what actions to take. Social workers, in this example, need to explain why the abuse has occurred, predict the likely consequences of different courses of action, and decide how to intervene. These aims of explanation and prediction resemble those of natural scientists. Whether the similarity can or should extend to social workers using the same methods as natural scientists has long been disputed. As in the social sciences generally, those who argue for a scientific approach (naturalists) are opposed by humanists who claim that understanding human actions requires different methods from those used in studying the natural world. The latter position has received most support in social work, particularly among fieldworkers. In this thesis, I shall challenge this majority view and argue that social workers can and should use scientific methods in order to develop the most effective ways of helping the many people in our society who have to rely on them. The thesis examines the philosophical debates underlying the conflicting views on science and argues that the widespread hostility to the use of scientific methods that exists among social workers is based on a false picture of them and hence an inaccurate understanding of how they can be used in social work. Philosophical debate, though abstract, is of practical importance. Social workers, seeing so much human suffering and bombarded with requests for help, might be inclined to dismiss philosophy as a luxury, an arcane subject which has little to do with their day-to-day work. But social workers inevitably take sides in the philosophical arguments and the position they take influences the help they offer to clients. In assessing the risk of child abuse, for example, they have to decide what evidence is relevant, how reliable it is, and how they can use it to make a prediction about the safety of a particular child. The social worker who favours the humanist approach may base his decision largely on an intuitive appraisal of the parents while his colleague who adopts a scientific approach will give more weight to empirical research evidence on risk factors. Their philosophical differences have practical consequences, affecting decisions about whether or not a child stays with his parents and, in a few cases where the predictions are disastrously wrong, whether he survives. Moreover, although the debate about using scientific methods in social work is as old as the profession itself. It has recently received increased attention because of issues in both social work and the philosophy of science. It is typically in times of trouble that disciplines become interested in their philosophical foundations and to many it appears that social work today is in difficulties. The steady growth in the statutory duties and powers given to the profession illustrates the increasing expectations society has of it to alleviate personal and social problems. But at the same time, doubts are increasing about the competence of social workers. The public have been shocked by a number of cause célébrés where children have been severely abused or murdered despite being under the supervision of social workers. Within the profession, unease has developed because, in many areas of practice, scientifically based evaluative research has failed to produce convincing evidence of effectiveness. In this unsettled period, attention turns to questions about what knowledge and skills social workers might have and how they can develop them. The philosophy of science also provides a motive for re-examining social workers' assumptions about how they might understand and help their clients. There have been developments in thinking about the nature of scientific reasoning which substantially alter the premises of the traditional debate about using scientific methods in studying human conduct. These philosophical changes have led to some re-appraisal of the disputes in social work and two opposing views are emerging. On the one hand, some propose a new argument against science, namely the relativists' claim that criticisms of the former account of 8 science also Invalidate the claim that science produces more reliable theories. Hence, it is said, science should no longer be held up as a model for social workers. On the other hand, it is argued that the more satisfactory empiricist account is not vulnerable to the criticisms humanists have traditionally levelled at science and so bridges the apparent gap between the two sides in the science debate. It is this view which I shall be presenting and defending throughout this thesis. OUTLINE OF THESIS My first aim is to show that these debates about knowledge are not just of interest to social workers but are of public significance. Chapter Two reports on the expanding role of social work in modern society and details the profession's increasing duties and powers laid down by parliament. In Chapter Three, I consider how social workers meet their responsibilities. A study of the nature of training programmes for social workers and the main approaches to fieldwork indicates that few use scientific methods in appraising theories or evaluating their work. Empirical research studies though cast serious doubt on the effectiveness of such a style of social work and provide grounds for arguing for a scientific approach. Most social workers, however, would argue not that they should not use scientific methods but that they cannot employ them when trying to understand and help human beings.

    The National Association of Social Workers (NASW) The Code offers a set of values, principles, and standards to guide decision making and conduct when ethical issues arise. It does not provide a set of rules Code of Ethics that prescribe how social workers should act in all situations. Specific applications of the Code must take into account the context in which it is being considered and the possibility of conflicts among the Code’s values, principles, Preamble and standards. Ethical responsibilities flow from all human relationships, from the personal and familial to the social and professional. The primary mission of the social work profession is to enhance human well- being and help meet basic human needs of all people, with particular attention Further, the NASW Code of Ethics does not specify which values, principles, and to the needs and empowerment of people who are vulnerable, oppressed, and standards are most important and ought to outweigh others in instances when living in poverty. A historic and defining feature of social work is the they conflict. Reasonable differences of opinion can and do exist among social profession’s focus on individual well-being in a social context and the well- workers with respect to the ways in which values, ethical principles, and ethical being of society. Fundamental to social work is attention to the environmental standards should be rank ordered when they conflict.

  • A Positivist Route for Explaining How Facts Make Law
    Legal Theory, 18 (2012), 139–207. c Cambridge University Press 2012 0361-6843/12 $15.00 + 00 doi:10.1017/S1352325212000079 A POSITIVIST ROUTE FOR EXPLAINING HOW FACTS MAKE LAW David Plunkett* Dartmouth College In “How Facts Make Law” and other recent work, Mark Greenberg argues that legal positivists cannot develop a viable constitutive account of law that meets what he calls the “the rational-relation requirement.” He argues that this gives us reason to reject positivism in favor of antipositivism. In this paper, I argue that Greenberg is wrong: positivists can in fact develop a viable constitutive account of law that meets the rational-relation requirement. I make this argument in two stages. First, I offer an account of the rational-relation requirement. Second, I put forward a viable positivist account of law that I argue meets this requirement. The account that I propose is a version of Scott Shapiro’s Planning Theory of Law. The version of Shapiro’s account that I propose combines (1) the account of concepts and conceptual analysis put forward by David Chalmers and Frank Jackson with (2) the account of the concept LEGAL INSTITUTION (and its conceptual connections to the concept LEGAL NORM)that we get from a certain reading of Shapiro’s Planning Theory. In addition to providing a compelling response to Greenberg’s argument in “How Facts Make Law,” I argue ∗ This paper has benefited enormously from a wide range of conversations and written comments. My greatest debt is to Scott Shapiro, who has helped me develop my basic argument over the last number of years.

Introduction: Social Work and Philosophy ROBERTA WELLS IMRE, COORDINATOR Study Group for Philosophical Issues in Social Work A journal issue unequivocally about philosophical concerns in social work is evidence of the recent progress we have made in the profession in recognizing the importance of philosoph- ical commitments in social work activities. Awareness of the presence of these commitments and dissatisfaction with conven- tional social work resources for addressing them led to the or- ganization of the Study Group for Philosophical Issues in 1985. The papers presented here have been contributed by members of this group, which is open to anyone interested in joining the conversation. Social work has always been a complex profession. Through- out its history awareness of human need has consistently exceeded available resources for providing help. Modern man- ifestations of this dilemma can be seen in the suffering of the homeless and the mentally ill on our streets and in other public places, in the pain of neglected and abused children, and in the distress of so many other people in trouble of one kind or an- other.

  • Social Work Practice and Social Science History
    Social Work &SOCIAL Social Sciences WORK Review PRACTICE 15(1) AND2011 pp.5-27.SOCIAL DOI:SCIENCE 10.1921/095352211X604291 HISTORY Social work practice and social science history Edgar Marthinsen1 Abstract: Social work may be regarded as a product of the Enlightment together with other social sciences. The ontological shift from religious perspectives to a secularly based responsibility that opens up for political as well as individual action is regarded as a baseline for modern social work. Social work itself has struggled to develop an academic identity and a sustainable social fi eld within the social sciences. Social work has historically experienced a gap between research and practice, relating to social sciences and other subjects as part of its teaching without a fi rm scientifi c foundation for social works own practice. If social work earlier developed related to ideas of welfare and social policy in practice it may now be moving in a new direction towards more than being based on scientifi c development within its own fi eld. Over the last decades the need for scientifi c development within social work has strengthened its relation to research and social science. There seems to be arguments to support that social work is moving with research in directions which may be regarded as an epistemological turn based on understanding of knowledge production as well as a linguistic turn where the construction of meaning enhance the importance of regarding different lifeworlds and worldviews as basis for claiming some egalitarian positions for different positions as clients as well as researchers and practitioners.

  • Strengths-Based Approach in Social Work: a Distinct Ethical Advantage
    International Journal of Innovation, Creativity and Change. www.ijicc.net Volume 3, Issue 2, November, 2017 Strengths-Based Approach in Social Work: A distinct ethical advantage Venkat Pulla , Australian Catholic University [email protected] The author believes that social work and human services professionals can see great outcomes when they work with the inherent strengths of individuals, family groups and organisations. Whenever we assist people in their recovery and their empowerment, our commitment to build on these inherent strengths goes a long way. In all humility this is about a way of asking the client three simple but pertinent questions: ‘What has worked for you before? What does not work for you? And what might work in the present situation for you?’ These three questions will allow facilitators and clients to make important changes in the processes and goals of engagement that will see through a variety of changes; as workers we are often wonderstruck as, with every change, clients seem to blossom. People pick up their bits and pieces and reconstruct hope for the future. In this paper the author will describe this approach in social work and expand on its assumptions and its core elements. Key words: Resilience, Strengths-based Practice, Strengths approach, Social Work, Empowerment 97 International Journal of Innovation, Creativity and Change. www.ijicc.net Volume 3, Issue 2, November, 2017 Introduction It is important at the outset to discuss the scope and objectives of this paper. In this paper, I intend focusing on the inherent strengths of individuals, families groups and organisations and how social work and human services professionals can utilise them to aid people’s recovery and empowerment (Pulla, 2013).

  • 1 Carnap, Kuhn , and the History of Science J.C. Pinto De Oliveira IFCH
    1 Carnap, Kuhn , and the history of science J.C. Pinto de Oliveira IFCH - Department of Philosophy State University of Campinas - Brazil [email protected] Abstract The purpose of this article is to respond to Thomas Uebel´s criticisms of my comments regarding the current revisionism of Carnap´s work and its relations to Kuhn. I begin by pointing out some misunderstandings in the interpretation of my article. I then discuss some aspects related to Carnap´s view of the history of science. First, I emphasize that it was not due to a supposed affinity between Kuhn´s conceptions and those of logical positivism that Kuhn was invited to write the monograph on the history of science for the Encyclopedia. Three other authors had been invited first, including George Sarton whose conception was entirely different from Kuhn´s. In addition, I try to show that Carnap attributes little importance to history of science. He seldom refers to it and, when he does, he clearly defends (like Sarton) a Whig or an “old” historiography of science, to which Kuhn opposes his “new historiography of science”. It is argued that this raises serious difficulties for those, like Uebel, who hold the view that Carnap includes the historical or the social within the rational. Keywords: Carnap, History of science, Kuhn, Logical positivism, New historiography of science, Philosophy of science, Revisionism, Sarton 1. Introduction In his article “Carnap and Kuhn: On the Relation between the Logic of Science and the History of Science”, published in 2011 in the Journal for General Philosophy of Science, Thomas Uebel responds to my criticism of what I call the revisionism of the logical positivist work, particularly its thesis regarding the compatibility or intimate relation between the philosophies of science of Carnap and Kuhn.

  • Teaching Philosophy
    TEACHING PHILOSOPHY My pedagogical approach is based on the social work principles of empowerment and praxis. I use a collaborative learning and teaching approach in the classroom that brings to life the social work theories and practice skills. Modeling community practice skills, I create a classroom environment that builds upon existing student knowledge, experiences, and intersecting social identities to support and challenge students to push their learning edges, fostering the development of critical thinking and concrete practice skills. While I specialize in social work macro practice, I feel strongly that students must be capable of bridging their micro, mezzo, and macro skills to use within and across various social contexts. Learning, practicing, and reflecting upon these skills in the classroom frame my social work pedagogy, and lie at the heart of social justice education and the social work profession (Adams, Bell, & Gruffin, 2007; Freire, 1971, 1994; hooks, 1994). Critical Pedagogy In order to foster students’ critical consciousness and deep learning, I start the semester with a series of exercises that allows students to get to know each other beyond their concentrations, start building trust, and develop an environment where we are all teachers and learners. I engage students in exercises where we discuss what it means to create a respectful and engaging classroom. In particular, we discuss the differences between safety and comfort, and how we can create a safe environment where we can turn conflict and discomfort into opportunities for learning and growth for everyone in the class. One area that often pushes student’s learning edge, often creating discomfort and conflict, involves discussions in class around how our social identities impact our social work practice.

  • Social Work Skills
    SOCIAL WORK SKILLS Beginning During the beginning phase, you introduce and identify yourself and seek introductions from prospective clients and involved others. Following the exchange of introductions, you describe a tentative initial purpose for the meeting, possibly identify one of more professional roles that you might undertake, orient participants to the process, and identify relevant policy and ethical factors that might apply. Throughout this beginning process, you regularly seek feedback concerning others’ understanding of and reactions to your introductory comments. By using the beginning skills, you help to clarify the nature and boundaries or ground rules of the helping process, lessen the initial ambivalence people often experience, and establish a tentative direction for work. Introducing Yourself At the beginning of any first interview, you should identify yourself by name and profession and by agency or departmental affiliation. You might also want to provide formal identification, such as a business card. Seeking Introductions Encourage each new client to say her or his name, and then try to pronounce it correctly. In a group, you might ask group members to introduce themselves and share a few of the thoughts that occurred to them as they anticipated coming to this first meeting. Describing Initial Purpose Clearly but succinctly discuss your view of the purpose of the meeting. Orienting Clients Describe how clients can join you as active, collaborative participants in the helping process. Discussing Policy and Ethical Factors Discuss potentially relevant legal, policy and ethical factors. This constitutes part of the informed consent process and is an essential element of professional service to clients.
