We investigate the use of a dynamic form of the EM algorithm to estimate proportions in finite mixtures of known distributions. We prove a consistency result for this algorithm, which employs only a single EM update for each new observation. Our aim is to demonstrate that the slow convergence rate of the EM algorithm in many applications is of little practical consequence in a situation when data is frequently being updated. 相似文献

AbstractThe value of learning from mental health lived experience is widely acknowledged, however, the nature of lived experience involvement in Australian social work education seldom extends beyond guest lecturing. Further, few opportunities exist that build the capacity of people with lived experience to become educators within tertiary settings. In this paper we present the Valuing Lived Experience Project (VLEP), an initiative led by a Lived Experience Academic (LEA) that seeks to systematically and meaningfully embed lived experience into the social work curriculum at a Western Australian university by providing significant opportunities for the capacity building of both individuals with mental health lived experience and academics. Given the relative infancy of service user involvement in Australian social work education, the VLEP offers a number of opportunities for reflection and consideration. A long-standing partnership between a LEA and Social Work Academic is described, the activities and key learnings of the VLEP to date are outlined, and we offer our reflections on challenges encountered throughout the journey. We hope that our experiences and learnings can be drawn upon to progress lived experience participation in tertiary settings and further legitimise lived experience involvement in the education of social workers. 相似文献

Casual employment is extensive and has been increasing for more than two decades in Australia. The concept of casual employment
used in the Australian context is unusual, but it is directly linked to benefit and rights exclusion within the regulatory
framework governing employment. The expansion in casual employment has spread across all sectors, industries and occupations.
Casual employment is associated with various forms of insecurity including income and employment insecurity. There are a number
of ways in which the insecurity associated with casual employment could be reduced.

This paper contests the major emphasis placed on the multidimensional nature of poverty measurement. Instead, it argues that
poverty pictures created by different measures and at different units of analysis tend to converge. This argument is derived
from a comparison of poverty pictures created using income and asset-based measures at the national and household level in
five South African Development Community countries. Although multidimensional measures have value in illuminating subtle differences,
the findings indicate a single dimension of poverty that runs throughout all the measures and levels of analysis. However,
despite the single poverty picture provided by different measures, the abandonment of these different measures is not supported.
Multidimensional measures provide insight into particular elements of poverty that is useful and relevant to poverty interventions. 相似文献

Individual differences in how mothers structure reminiscing about shared past experiences with their preschool children are
related to children’s developing autobiographical memory skills and understanding of self and emotion. More specifically,
mothers who engage in highly elaborative reminiscing have children who come to tell more coherent and emotionally expressive
autobiographical narratives, and these children also show better understanding of self and are better able to regulate emotion
than children of less elaborative mothers. This body of research is reviewed and relations between maternal reminiscing style
and children’s developing self and emotional understanding are explicated.

Data from a participant-observational study of the tarot are used to explore the social meanings of modern occultism and to examine certain rival contentions about these beliefs, practices, adherents, and the manner in which activities are or are not organized socially. Unlike collective behavioral audiences, which employ occultisms as a form of popular entertainment, the occult practitioners reported here participate in an “esoteric community” involving practitioner-client relations, social networks, and small cult-like groups. Although the occult tarot constitutes an elaborate theosophy, contemporary adherents selectively subscribe to these doctrines and they freely mix the occult, other esoteric teachings, and elements of traditional culture. When the tarot is used in a divinatory fashion as a service to the general public for pay, problems of legitimacy commonly arise. Occultists in the community deal with this problem by presenting themselves as “professionals.” Within the nominally pluralistic climate of American society, occultisms thereby become another path to dealing meaningfully with life's problems and expressing individual identity. Organized in terms of loose collections of practitioners and groups and supported by the larger cultic milieu, occult communities represent an adaptation to modern society which is likely to persist long after particular groups fail or particular individuals move on to other social scenes. 相似文献

Collaboration has been enacted as a core strategy by both the government and nongovernment sectors to address many of the intractable issues confronting contemporary society. The cult of collaboration has become so pervasive that it is now an elastic term referring generally to any form of ‘working together’. The lack of specificity about collaboration and its practice means that it risks being reduced to mere rhetoric without sustained practice or action. Drawing on an extensive data set (qualitative, quantitative) of broadly collaborative endeavours gathered over 10 years in Queensland, Australia, this paper aims to fill out the black box of collaboration. Specifically it examines the drivers for collaboration, dominant structures and mechanisms adopted, what has worked and unintended consequences. In particular it investigates the skills and competencies required in an embedded collaborative endeavour within and across organisations. Social network analysis is applied to isolate the structural properties of collaborations over other forms of integration as well as highlighting key roles and tasks. Collaboration is found to be a distinctive form of working together, characterised by intense and interdependent relationships and exchanges, higher levels of cohesion (density) and requiring new ways of behaving, working, managing and leading. These elements are configured into a practice framework. Developing an empirical evidence base for collaboration structure, practice and strategy provides a useful foundation for theory extension. The paper concludes that for collaboration, to be successfully employed as a management strategy it must move beyond rhetoric and develop a coherent model for action. 相似文献
