Assessment of influence in non-linear measurement error models

We consider the assessment of outliers and influential observation in non-linear measurement error models. Residuals, leverage measures and case-deletiondiagonostics are examined. The method of local influence is also applied to the models. In particular, the perturbation of measurement error variances has been found useful in assessing the adequancy of the model assumptions. A numerical example is given to illustrate the application of the diagonostics.     

Optimal orthogonal-array-based latin hypercubes

The use of optimal orthogonal array latin hypercube designs is proposed. Orthogonal arrays were proposed for constructing latin hypercube designs by Tang (1993). Such designs generally have better space filling properties than random latin hypercube designs. Even so, these designs do not necessarily fill the space particularly well. As a result, we consider orthogonal-array-based latin hypercube designs that try to achieve optimality in some sense. Optimization is performed by adapting strategies found in Morris & Mitchell (1995) and Ye et al. (2000). The strategies here search only orthogonal-array-based latin hypercube designs and, as a result, optimal designs are found in a more efficient fashion. The designs found are in general agreement with existing optimal designs reported elsewhere.     

Disabled by Design

This paper describes and analyses the author's attempts to engage in a user-led design/research process. This was undertaken during an MA in Design Research for Disability. The first section of the study delineates the background and context of the process of inquiry. This involves examination of the common features within design participation and emancipatory research. The second section of the study uses six principles of emancipatory research, defined by Emma Stone and Mark Priestley (1996), as a framework for analysis of the author's own process of inquiry.     

Communicating Global Activism

Many observers doubt the capacity of digital media to change the political game. The rise of a transnational activism that is aimed beyond states and directly at corporations, trade and development regimes offers a fruitful area for understanding how communication practices can help create a new politics. The Internet is implicated in the new global activism far beyond merely reducing the costs of communication, or transcending the geographical and temporal barriers associated with other communication media. Various uses of the Internet and digital media facilitate the loosely structured networks, the weak identity ties, and the patterns of issue and demonstration organizing that define a new global protest politics. Analysis of various cases shows how digital network configurations can facilitate: permanent campaigns; the growth of broad networks despite relatively weak social identity and ideology ties; transformation of individual member organizations and whole networks; and the capacity to communicate messages from desktops to television screens. The same qualities that make these communication-based politics durable also make them vulnerable to problems of control, decision-making and collective identity.     

Research project on advocacy and autism

This article presents the findings of a qualitative research project about the difficulties in accessing advocacy faced by adults labelled as having autism and Asperger's Syndrome in the Northwest of England. It is also an example of partnership working between three organisations. The article examines both the process of team-led (emancipatory) research and the project findings. Seven main themes emerged throughout the research: late diagnosis and lack of service support; bad experiences with systems of care; feelings of 'not belonging' (identity issues); barriers around communication and sensitivity towards individuals; lack of awareness and access to advocacy and rights; difficulties of 'fitting into' what is already available; and interest in developing knowledge around advocacy. Examination of the main themes pointed to a disturbing link between poor service response, episodes of crisis and mental ill health. The Carlisle People First Research Team is made up of 6 researchers who are labelled as having 'learning difficulties' who work in partnership with one other researcher.     

Complex belief-desire reasoning in children

Previous research concerned with children's belief-desire psychology has examined the capacity to predict or interpret action on the basis of the implicit proposition that ‘when an actor desires a particular end and believes that a particular action will achieve that end, he or she will undertake that action’. The limitations of this formulation for understanding acts of omission are outlined and an elaborated version of belief-desire psychology introduced. This version holds that ‘when an actor desires a particular end and believes that a particular action will achieve that end, and when it is believed that there are no co-occurring outcomes of that action whose avoidance is desired more highly than is the originally conceived end, then the actor will undertake the action which will satisfy the original desire’. An experiment is reported which examines 4-, 5, and 7-year-olds' ability to predict story characters' actions on the basis of either their true or false beliefs concerning undesirable outcomes associated with the pursuit of a desired end. Children of all age-groups provided evidence of understanding the elaborated version of belief-desire psychology. However, a significant improvement was noted between the ages of 4 and 7 years in the ability to understand circumstances involving false beliefs.     

Clinical Writing of a Therapy in Progress: Ethical Questions and Therapeutic Challenges

Clinical implications and ethical dilemmas of the use of confidential case material in clinical writing are examined, including a review of the discourse among professionals who publish clinical work. This literature is applied to a clinical illustration of psychotherapy with a client who gave consent for publication and read the clinical write-up of her case material. It is suggested that clinical writing may increase client “self-reflection” if there is a “secure base” of attachment between therapist/author and the client. The impact on the client’s treatment process is examined, in addition to a discussion of ethical questions and professional recommendations. ²Dr. Susanne Bennett is an Assistant Professor, National School of Social Service of the Catholic University of America. Dr. Bennett is also a psychotherapist in private practice in Falls Church, VA.     

Avoiding responsibility: The politics and discourse of European development policy

This book deals with an important subject. Regrettably, it doesnot do so in a wholly successful way. The author's general purposeis to steer a path between a normative–ethical approachto the topic and a political–scientific one, and the mainmethodological stance adopted is a version of discourse analysis.Drawing, in particular, on the work of Laclau and Mouffe, sheexamines two discursive ‘moments’ in European developmentdiscourse, or two different ways of justifying European developmentpolicy – responsibility and efficiency. The first, atleast in the early stages of European policy, entailed a paternalisticsense of European concern for its former colonial possessions,while the latter legitimizes     

Supporting the Posts in Development Discourse: Under‐development,Over‐development,Post‐development

This article seeks to introduce scholars outside of development studies to post‐development thought, and to restate its relevance and value to those working within the development field. It begins with an overview of post‐development thought and its critique of the post‐World War Two development project. Following this, specific critiques levelled at post‐development thought and various responses to these are considered. In the last section, the possibility or desirability of raising the living standards of Third World people to a level comparable to those of the First World through economically based development strategies is questioned. The article concludes by drawing attention to First World overdevelopment and the continued value of post‐development thinking in unsettling the development trajectory for either the First or Third World.
