A comparison of the dental health of Brazilian and Canadian independently living elderly

Objective: To compare the dental status of Brazilian and Canadian elderly populations with respect to socioeconomic and quality of life factors. Materials and methods: A total of 496 adults aged 60-75 years, having four or more teeth, and physically and cognitively suitable for a clinical oral examination were included. Subjects answered questions concerning their lifestyle and completed the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. Results: In all populations, the majority were females, aged between 60 and 65 years and married. Although the Canadian New Immigrant population had lower mean income, they had more remaining teeth (23.04 +/- 6.1), more functional teeth (sound and restored teeth) (14.92 +/- 5.7), more sound teeth (15.40 +/- 7.6), but more carious teeth (2.97 +/- 3.0). The Brazilian population had higher numbers of restored teeth (12.26 +/- 6.8) and fewer remaining teeth (17.80 +/- 7.6). In all populations, females, married and younger (60-65 years old) adults were more likely to retain 20 or more teeth. The mean GOHAI scores were similar for Canadians (40.55 +/- 5.7) and Canadian New Immigrants (39.28 +/- 6.5), but were higher than that among Brazilians (31.97 +/- 8.9). Conclusions: The numbers of remaining teeth were related to greater education and higher income status for Brazilian and Canadian populations. However, Canadian New Immigrants with lower income and education retained more teeth than the other populations.

Hypercapitalism: Language, new media and social perceptions of value

Using examples from contempoary policy and business discourses, and exemplary historical texts dealing with the notion of value, I put forward an argument as to why a critical scholarship that draws on media history, language analysis, philosophy and political economy is necessary to understand the dynamics of what is being called 'the global knowledge economy'. I argue that the social changes associated with new modes of value determination are closely associated with new media form.

The socio-religious beliefs and nature of the contemporary Vampire Subculture

The contemporary Vampire Subculture can be defined as a multi-faceted, socio-religious movement with its own distinct collective community and network of participants who share a similar belief system and customary lifestyle that reflect their concept of the vampire. The Vampire Subculture consists of individuals who profess to be 'real vampires', vampire communities of like-minded persons, 'blood-donors' who willingly allow vampires to partake of them, occult-based and mystical-orientated groups that appeal to their spirituality, the blood fetishists, and the live-action vampire role-players. In response, a Christian counter-movement of self-proclaimed 'vampire-slayers' has emerged that actively opposes the vampire subculture and its beliefs and practices. The socio-religious nature of the Vampire Subculture can be best described as a Segmented, Polycentric and Integrated Network of participants.

Complex language functions and subcortical mechanisms: evidence from Huntington's disease and patients with non-thalamic subcortical lesions

The neuropathological changes associated with Huntington's disease (HD) are most marked in the head of the caudate nucleus and, to a lesser extent, in the putamen and globus pallidus, suggesting that at least part of the language impairments found in patients with HD may result from non-thalamic subcortical (NTS) pathology. The present study aimed to test the hypothesis that a signature profile of impaired language functions is found in patients who have sustained damage to the non-thalamic subcortex, either focally induced or resulting from neurodegenerative pathology. The language abilities of a group of patients with Huntington's disease (n=13) were compared with those of an age- and education-matched group of patients with chronic NTS lesions following stroke (n=13) and a non-neurologically impaired control group (n=13). The three groups were compared on language tasks that assessed both primary and more complex language abilities. The primary language battery consisted of The Western Aphasia Battery and The Boston Naming Test, whilst the more complex cognitive-linguistic battery employed selected subtests from The Test of Language Competence-Expanded, The Test of Word Knowledge and The Word Test-Revised. On many of the tests of primary language function from the Western Aphasia Battery, both the HD and NTS participants performed in a similar manner to the control participants. The language performances of the HD participants were significantly more impaired (p<0.05 using modified Bonferroni adjustments) than the control group, however, on various lexico-semantic tasks (e. g. the Boston Naming Test and providing definitions), on both single-word and sentence-level generative tasks (e. g. category fluency and formulating sentences), and on tasks which required interpretation of ambiguous, figurative and inferential meaning. The difficulties that patients with HD experienced with tasks assessing complex language abilities were strikingly similar, both qualitatively and quantitatively, to the language profile produced by NTS participants. The results provide evidence to suggest that a signature language profile is associated with damage to the non-thalamic subcortex resulting from either focal neurological insult or a degenerative disease.

Magic happens: Revisiting the spirituality and social work debate

The social work profession is currently undergoing a resurgence of interest regarding the issue of spirituality in social work. This article attempts to summarise and explore the debate so far and to discuss the implications of this in a practice context. Current issues including definitions of spirituality and the key concerns in the areas of both practice and education are addressed. The article concludes with an overview of a model of spiritually sensitive social work practice, and poses options for further professional reflection on the place of spirituality in social work practice.

Social work, stress and burnout: A review

Stress and burnout for health care professionals have received increasing attention in the literature. Significant administrative, societal and political changes have impacted on the role of workers and the responsibilities they are expected to assume. Most writers suggest that social work is a highly stressful occupation, with stress deriving in particular from role conflict between client advocacy and meeting agency needs. This article reviewed the social work literature with two questions in mind: Are social workers subject to greater stress than other health professionals? What factors contribute to stress and burnout among social workers? We found that most of the literature was either anecdotal or compared social worker stress with general population norms rather than with stress levels of workers in comparable professions. Such empirical research as is available suggests that social workers may experience higher levels of stress and resulting burnout than comparable occupational groups. Factors identified as contributing to stress and burnout included the nature of social work practice, especially tension between philosophy and work demands and the organization of the work environment. There was some evidence that supervision and team support are protective factors.

Urbanization, population transition, and growth

This paper analyzes a dual economy consisting of urban market areas and less developed rural areas with or without local markets. Urban areas have better opportunities for earnings and education than rural areas. Rural families choose whether to move to urban areas at costs that differ from location to location. As per capita output grows relative to the moving cost, urbanization proceeds, leading to lower fertility, more investments in human and physical capital per child relative to output per worker, and faster economic growth. These impacts are stronger if rural areas have no access to markets.
