Comparison of Modes of Administration and Response Options in the Assessment of Subjective Health Using the First Question of SF-36

To compare two modes of administration (self-administered; by interviewer) and two response options format (using words; images of “facial-expressions”) of the first question of SF-36 (Q1SF-36), and to test its validity. We included 825 participants (20–90 years). Q1SF-36, using words or images, was included in a global questionnaire interview and at the end participants filled the SF-36. The agreement was tested by weighted kappa coefficients (WKappa). Classification Trees were used in the calibration of Q1SF-36 responses, with the physical (PDSF36) and mental dimensions of SF-36. Polyserial correlation coefficients and areas under the ROC curves (AUC) were used for validation. After categorization, using PDSF36 classification trees, the WKappa were 0.770 (self-administered vs. interviewer), 0.569 (self-administered vs. facial-expressions) and 0.566 (interviewer vs. facial-expressions). The WKappa between the PDSF36 and the modes (self-administered, interviewer and facial-expressions) were 0.784, 0.713 and 0.579 and the corresponding polyserial correlation coefficients were 0.784, 0.713 and 0.579. A good discriminatory power was found comparing the modes with the PDSF36 (AUC = 0.907, 0.923 and 0.827), but not with mental dimension (AUC = 0.538, 0.501 and 0.629). The Q1SF-36, by self-administration or interviewer, may be a valid alternative for assessment of subjective physical health, but not mental health.     

Zen and the art of aut-ethnography: a tribute to Robert M. Pirsig

With the passing of Robert M. Pirsig, I felt that it was an appropriate time to write a tribute to his work and the influence it has had on my own theorising in regard to autistic ways of being. This reflection utilises the concept of an ‘aut-ethnography’ to examine passages that I had highlighted word by word when I first read Pirsig’s book: Zen and the Art of Motorcycle Maintenance. These fragments contain links to a number of theoretical ‘lines of flight’ within my own work and that of others, from his concepts of dynamic ‘quality’ to his discussion on the tension between scientific method and lived experience.     

Advancing Social Capital Measurement: Using General Social Survey Cycles to Develop an Efficient Survey Instrument

The General Social Survey (GSS) has provided significant insight about the state of societies around the world through the International Social Survey Programme (ISSP). Although broadly applicable, in this study the context for developing a new social capital survey instrument covers the Canadian GSS since 1985. Questions in the GSS are often used by researchers who are interested in specific questions or themes for use in some form of re-sampling. Given significant social and relational themes, GSS cycles from 1985 to 2013 were reviewed using a social capital framework to produce a new Social Capital GSS survey instrument. A process of vetting and sorting questions led to development of a 41 question instrument that includes 16 demographic and context variables and 25 social network and trust variables. After testing and refinement, the instrument was used with a randomly sampled group across selected East Hamilton Census Tracts that are differentiated by median income and a standard deviation above and below respectively (n?=?97).     

Control of interrelated research and development projects

The purpose of this paper is to examine a type of resource allocation problem arising in the context of research and development activities. The particular problem analyzed involves scheduling a group of projects in such a way that total cost is minimized while several precedence relations are satisfied and specific completion times are maintained. The primary difficulty results from the existence of commonalities that allow the successful completion of a particular project to be applied to several different purposes. A solution approach is developed which combines a one-pass network algorithm to deal with the precedence and time restrictions and a dynamic programming procedure to allocate the resources to each project.     

Mind the gap! translating practice problems into research questions in an evaluation of a welfare programme

In the current environment of constrained budgets and growing pressure for an empirically based practice, the need for bridging the gap between practice and research in social work is challenged. The purpose of this article is to illustrate how - in a collaborative partnership between practitioners and researchers - problems experienced by practitioners have been formulated as research questions, outcomes, and measurable indicators in an evaluation of a new intervention programme addressing social assistance.
