Mixture Multi-state Markov Regression Model

Although heterogeneity across individuals may be reduced when a two-state process is extended into a multi-state process, the discrepancy between the observed and the predicted for some states may still exist owing to two possibilities, unobserved mixture distribution in the initial state and the effect of measured covariates on subsequent multi-state disease progression. In the present study, we developed a mixture Markov exponential regression model to take account of the above-mentioned heterogeneity across individuals (subject-to-subject variability) with a systematic model selection based on the likelihood ratio test. The model was successfully demonstrated by an empirical example on surveillance of patients with small hepatocellular carcinoma treated by non-surgical methods. The estimated results suggested that the model with the incorporation of unobserved mixture distribution behaves better than the one without. Complete and partial effects regarding risk factors on different subsequent multi-state transitions were identified using a homogeneous Markov model. The combination of both initial mixture distribution and homogeneous Markov exponential regression model makes a significant contribution to reducing heterogeneity across individuals and over time for disease progression.     

Performativity and helping professions: social theory, power and practice

Drawing on Judith Butler's conception of 'performativity', we would argue that the notion has important implications for contemporary debates in international social welfare over agency, subjection and 'resistance'. Professional social workers embedded in discursive institutions function according to particular expectations around performativity. In addition, this organisational context is complex with multiple demands. In light of technologies of surveillance and control in contemporary social work, performativity offers a response to the pressing need to expand notions of worker opposition beyond traditional forms of organised dissent towards the production of subjective space.     

Using the 2001 census to study human capital movements affecting Britain's larger cities: insights and issues

Summary.  Human capital is increasingly being recognized as crucial to the sustained growth of British cities, and the population census is unrivalled as a source of data on the characteristics of people moving to and from cities. Taking advantage of new features in the 2001 census, the paper examines how successful 27 of Britain's largest cities and their regions are in maintaining their labour force complement, giving particular attention to young adults and people working in high level occupations. Considerable variation is apparent between city regions, but the interpretation of results is somewhat hampered by limitations in the census data, prompting recommendations for future data collection.     

Young sexual abusers: conceptual frameworks,issues and imperatives

The problem of young people who sexually abuse others has emerged in the United Kingdom during the 1990s. This article briefly overviews the incidence and characteristics of young sexual abusers, anchors current concerns within broader studies of childhood and childhood sexuality and reflects on the likely impacts of recent policy and legislative changes on the management of young sexual abusers. Suggestions for areas of future research and strategic response are offered by way of conclusion. Copyright © 1999 John Wiley & Sons, Ltd.     

Globalisation and the Rural Poor

This article surveys how globalisation is affecting rural poverty. The forces of change may affect the welfare of the rural poor through their influence on productivity, growth, income distribution, technologies, the security of livelihoods, and policies. There are both credit and debit entries: large potential benefits, for example from accelerated growth, but also real dangers that the rural poor will be left behind, for example that they will not have access to the knowledge and other assets necessary for success in a commercialised world. The article also discusses some of the influences on the ways the forces of change work themselves out, stressing the importance of market access, positive government policy stances and the assets of the rural poor.

Paradoxes, locations and the need for social coherence: a qualitative study of living with a learning difficulty

Policy rhetoric over recent decades has promoted social inclusion of the more vulnerable sectors of society, such as people with learning difficulties. This study aimed to describe the experiences of people who live with learning difficulties in order to inform local service development. Thirty-five people with a learning difficulty and/or a family member were interviewed. A model of social coherence was developed that moves beyond the self-limiting debates about social inclusion and exclusion. It is underpinned by a sense of location for the person with a disability in relation to services and carers, family and community, dependency and risk, temporality and space, events, control and society. Key recommendations are for services to know the individual and his/her family; to be responsive to individual needs; to enhance the capacity of families and communities to support people with difficulty in learning; and to help these people to feel more valued.     

Beyond Managism: Negotiated Narratives and Critical Management Education in Practice

A pragmatist conception of critical management education and learning is first set out. This accepts a degree of 'functionality' between management study and management practice. It is, however, a non-managerialist and non-technicist functionality. The criterion for judging critical management learning cannot be how well it reveals truths in any absolute or foundationalist sense. The only possible criterion is how well, relative to alternative types of learning, it informs the practices of people involved in managerial situations (regardless of whether these are managers or not). Next, one way of applying pragmatist critical management principles is outlined. This works through negotiated narratives and stands as an alternative to orthodox management education approaches – ones to which the critical concept of scholarism is applied. The outline is then developed through an ethnographic style account of an instance of such a practice. Central to this piece of teaching and learning practice is the critical concept of managism . Managist discourse and its role in framing managerial thinking and practices is examined and debated by the management class in the process of attempting collectively to make sense of stories brought to the class by both the students and the teacher. The basic 'story' that the paper tells is rehearsed at the end in the form of a fairy tale. This is done as an alternative to concluding or 'closing' the paper. The story of critical management education and learning and what is done in its name continues to unfold.     

Augmented or admented reality? The influence of marketing on augmented reality technologies

As mobile and wearable devices that enable digital content to be displayed over physical surroundings continue to develop, scholars are increasingly interested in these ‘augmented reality’ (AR) technologies. While much of the focus has either been on the technological development of these devices and their potential for changing user perception, there has been less attention paid to the stakeholders and companies developing these technologies. This study examines developments in the industry itself, where companies are finding resources and structuring their businesses, and how this has created a momentum toward marketing and advertising. The intricate link between marketing and AR is one that has implications for how the technology is developing, what experiences are possible through the technology, and the future contexts in which AR is deployed.
