Mental health telemedicine programmes in Australia

A national survey of mental health telemedicine programmes was conducted and data collected on their catchment areas, organizational structure, equipment, clinical and non-clinical activity, and use by populations who traditionally have been poorly served by mental health services in Australia. Of 25 programmes surveyed, information was obtained for 23. Sixteen programmes had dealt with a total of 526 clients during the preceding three months. Of these, 397 (75%) were resident in rural or remote locations at the time of consultation. Thirty-seven (7%) were Aboriginals or Torres Strait Islanders. Only 19 (4%) were migrants from non-English-speaking backgrounds. The programmes provided both direct clinical and secondary support services. Overall, the number of videoconferencing sessions devoted to clinical activity was low, the average being 123 sessions of direct clinical care per programme per year. Videoconferencing was also used for professional education, peer support., professional supervision, administration and linking families. The results of the study suggest that telehealth can increase access to mental health services for people in rural and remote areas, particularly those who have hitherto been poorly served by mental health services in Australia.

Timing and magnitude of peak height velocity and peak tissue velocities for early, average, and late maturing boys and girls

Height, weight, and tissue accrual were determined in 60 male and 53 female adolescents measured annually over six years using standard anthropometry and dual-energy X-ray absorptiometry (DXA). Annual velocities were derived, and the ages and magnitudes of peak height and peak tissue velocities were determined using a cubic spline fit to individual data. Individuals were rank ordered on the basis of sex and age at peak height velocity (PHV) and then divided into quartiles: early (lowest quartile), average (middle two quartiles), and late (highest quartile) maturers. Sex- and maturity-related comparisons in ages and magnitudes of peak height and peak tissue velocities were made. Males reached peak velocities significantly later than females for all tissues and had significantly greater magnitudes at peak. The age at PHV was negatively correlated with the magnitude of PHV in both sexes. At a similar maturity point (age at PHV) there were no differences in weight or fat mass among maturity groups in both sexes. Late maturing males, however, accrued more bone mineral and lean mass and were taller at the age of PHV compared to early maturers. Thus, maturational status (early, average, or late maturity) as indicated by age at PHV is inversely related to the magnitude and late maturers for weight and fat mass in boys and girls. Am. J. Hum.

Validation of the Edinburgh Postnatal Depression Scale for men, and comparison of item endorsement with their partners

Background: The Edinburgh Postnatal Depression Scale (EPDS) has been validated and used extensively in screening for depression in new mothers, both in English speaking and non-English speaking communities. While some studies have reported the use of the EPDS with Fathers, none have validated it for this group, and thus the appropriate cut-off score for screening for depression or anxiety caseness for this population is not known. Method: Couples were recruited antenatally and interviewed at six weeks postpartum. EPDS scores and distress caseness (depression or anxiety disorders) for 208 fathers and 230 mothers were determined using the Diagnostic Interview Schedule. Results: Analyses of the EPDS for fathers using distress caseness (depression or anxiety disorders) as the criterion shows that a cut-off of 5/6 has optimum receiver operating characteristics. Furthermore acceptable reliability (split-half and internal consistency) and validity (concurrent) coefficients were obtained. For mothers the optimum cut-off screening value to detect distress caseness was 7/8. Item analysis revealed that fathers endorsed seven of the ten items at lower rates to mothers, with the most significant being that referring to crying. Conclusions: The EPDS is a reliable and valid measure of mood in fathers. Screening for depression or anxiety disorders in fathers requires a two point lower cut-off than screening for depression or anxiety in mothers, and we recommend this cut-off to he 5/6.

Heritabilities of Apolipoprotein and Lipid Levels in Three Countries

This study investigated the influence of genes and environment on the variation of apolipoprotein and lipid levels, which are important intermediate phenotypes in the pathways toward cardiovascular disease. Heritability estimates are presented, including those for apolipoprotein E and All levels which have rarely been reported before. We studied twin samples from the Netherlands (two cohorts; n = 160 pairs, aged 13-22 and n = 204 pairs, aged 34-62), Australia (n = 1362 pairs, aged 28-92) and Sweden (n = 302 pairs, aged 42-88). The variation of apolipoprotein and lipid levels depended largely on the influences of additive genetic factors in each twin sample. There was no significant evidence for the influence of common environment. No sex differences in heritability estimates for any phenotype in any of the samples were observed. Heritabilities ranged from 0.48-0.87, with most heritabilities exceeding 0.60. The heritability estimates in the Dutch samples were significantly higher than in the Australian sample. The heritabilities for the Swedish were intermediate to the Dutch and the Australian samples and not significantly different from the heritabilities in these other two samples. Although sample specific effects are present, we have shown that genes play a major role in determining the variance of apolipoprotein and lipid levels in four independent twin samples from three different countries.

Gene-Environment Interaction Effects on Behavioral Variation and Risk of Complex Disorders: The Example of Alcoholism and Other Psychiatric Disorders

There have been few replicated examples of genotype x environment interaction effects on behavioral variation or risk of psychiatric disorder. We review some of the factors that have made detection of genotype x environment interaction effects difficult, and show how genotype x shared environment interaction (GxSE) effects are commonly confounded with genetic parameters in data from twin pairs reared together. Historic data on twin pairs reared apart can in principle be used to estimate such GxSE effects, but have rarely been used for this purpose. We illustrate this using previously published data from the Swedish Adoption Twin Study of Aging (SATSA), which suggest that GxSE effects could account for as much as 25% of the total variance in risk of becoming a regular smoker. Since few separated twin pairs will be available for study in the future, we also consider methods for modifying variance components linkage analysis to allow for environmental interactions with linked loci.

Morphology of the spermatozoa of the Microhylidae (Anura, Amphibia)

Microhylid spermatozoa show the autapomorphic condition of possessing a thin post-mitochondrial cytoplasmic collar. Their spermatozoa are apomorphic in several respects. They have lost the distinct nuclear shoulder, endonuclear canal and axial perforatorium observed in urodeles, caecilians and primitive frogs, possess a conical perforatorium and apomorphically lack any fibres associated with the axoneme. The spermatozoa of Cophixalus , however, differ in several respects from those of the other microhylids examined. Cophixalus spermatozoa are longer in almost all measurements, the acrosome vesicle is cylindrical and does not completely cover the putative perforatorium, the perforatorium is asymmetrical and composed of fine fibres, the nucleus is strongly attenuated and narrower, and the mitochondria are elongate. The absence of fibres associated with the axoneme is an apomorphic condition shared with the Ranidae, Rhacophoridae and Pipidae.

Perception or synthesized voice quality in connected speech by Cantonese speakers

Perceptual voice analysis is a subjective process. However, despite reports of varying degrees of intrajudge and interjudge reliability, it is widely used in clinical voice evaluation. One of the ways to improve the reliability of this procedure is to provide judges with signals as external standards so that comparison can be made in relation to these anchor signals. The present study used a Klatt speech synthesizer to create a set of speech signals with varying degree of three different voice qualities based on a Cantonese sentence. The primary objective of the study was to determine whether different abnormal voice qualities could be synthesized using the built-in synthesis parameters using a perceptual study. The second objective was to determine the relationship between acoustic characteristics of the synthesized signals and perceptual judgment. Twenty Cantonese-speaking speech pathologists with at least three years of clinical experience in perceptual voice evaluation were asked to undertake two tasks. The first was to decide whether the voice quality of the synthesized signals was normal or not. The second was to decide whether the abnormal signals should be described as rough, breathy, or vocal fry. The results showed that signals generated with a small degree of aspiration noise were perceived as breathiness while signals with a small degree of flutter or double pulsing were perceived as roughness. When the flutter or double pulsing increased further, tremor and vocal fry, rather than roughness, were perceived. Furthermore, the amount of aspiration noise, flutter, or double pulsing required for male voice stimuli was different from that required for the female voice stimuli with a similar level of perceptual breathiness and roughness. These findings showed that changes in perceived vocal quality could be achieved by systematic modifications of synthesis parameters. This opens up the possibility of using synthesized voice signals as external standards or anchors to improve the reliability of clinical perceptual voice evaluation.

Engaging with theories of dialogue and voice: Using Bakhtin as a framework to understand teaching and learning Indigenous Australian women's performance

In this paper I explore the Indigenous Australian women's performance classroom (hereafter ANTH2120) as a dialectic and discursive space where the location of possibility is opened for female Indigenous performers to enter into a dialogue from and between both non-Indigenous and Indigenous voices. The work of Bakhtin on dialogue serves as a useful standpoint for understanding the multiple speaking positions and texts in the ANTH2120 context. Bakhtin emphasizes performance, history, actuality and the openness of dialogue to provide an important framework for analysing multiple speaking positions and ways of making meaning through dialogue between shifting and differing subjectivities. I begin by briefly critiquing Bakhtin's "dialogic imagination" and consider the application and usefulness of concepts such as dialogism, heteroglossia and the utterance to understanding the ANTH2120 classroom as a polyphonic and discursive space. I then turn to an analysis of dialogue in the ANTH2120 classroom and primarily situate my gaze on an examination of the interactions that took place between the voices of myself as family/teacher/student and senior Yanyuwa women from the r e m o t e N o r t h e r n T e r r i t o r y A b o r i g i n a l c o m m u n i t y o f B o r r o l o o l a as family/performers/teachers. The 2000 and 2001 Yanyuwa women's performance workshops will be used as examples of the way power is constantly shifting in this dialogue to allow particular voices to speak with authority, and for others to remain silent as roles and relationships between myself and the Yanyuwa women change. Conclusions will be drawn regarding how my subject positions and white race privilege affect who speaks, who listens and on whose terms, and further, the efficacy of this pedagogical platform for opening up the location of possibility for Indigenous Australian women to play a powerful part in the construction of knowledges about women's performance traditions.

The genetics of coronary heart disease: the contribution of twin studies

Despite the decline in coronary heart disease in many European countries, the disease remains an enormous public health problem. Although we know a great deal about environmental risk factors for coronary heart disease, a heritable component was recognized a long time ago. The earliest and best known examples of how our genetic constitution may determine cardiovascular risk relate to lipoprotein(a), familial hypercholesterolaemia and apolipoprotein E. In the past 20 years a fair number of polymorphisms assessed singly have shown strong associations with the disease but most are subject to poor repeatability. Twins constitute a compelling natural experiment to establish the genetic contribution to coronary heart disease and its risk factors. GenomEUtwin, a recently funded Framework 5 Programme of the European Community, affords the opportunity of comparing the heritability of risk factors in different European Twin Registries. As an illustration we present the heritabilities of systolic and diastolic blood pressure, based on data from over 4000 twin pairs from six different European countries and Australia. Heritabilities for systolic blood pressure are between 52 and 66% and for diastolic blood pressure between 44 and 66%. There is no evidence of sex differences in heritability estimates and very little to no evidence for a significant contribution of shared family environment. A non-twin based prospective case/cohort study of coronary heart disease and stroke (MORGAM) will allow hypotheses relating to cardiovascular disease, generated in the twin cohorts, to be tested prospectively in adult populations. Twin studies have also contributed to our understanding of the life course hypothesis, and GenomEUtwin has the potential to add to this.

Genetic and Environmental Influences on Migraine: A Twin Study Across Six Countries

Migraine is a common neurovascular brain disorder that is manifested in recurrent episodes of disabling headache. The aim of the present study was to compare the prevalence and heritability of migraine across six of the countries that participate in GenomEutwin project including a total number of 29,717 twin pairs. Migraine was assessed by questionnaires that differed between most countries. It was most prevalent in Danish and Dutch females (32% and 34%, respectively), whereas the lowest prevalence was found in the younger and older Finnish cohorts (13% and 10%, respectively). The estimated genetic variance (heritability) was significant and the same between sexes in all countries. Heritability ranged from 34% to 57%, with lowest estimates in Australia, and highest estimates in the older cohort of Finland, the Netherlands, and Denmark. There was some indication that part of the genetic variance was non-additive, but this was significant in Sweden only. In addition to genetic factors, environmental effects that are non-shared between members of a twin pair contributed to the liability of migraine. After migraine definitions are homogenized among the participating countries, the GenomEUtwin project will provide a powerful resource to identify the genes involved in migraine.

Evidence for a QTL on chromosome 19 influencing LDL cholesterol levels in the general population

The genetic basis of cardiovascular disease (CVD) with its complex etiology is still largely elusive. Plasma levels of lipids and apolipoproteins are among the major quantitative risk factors for CVD and are well-established intermediate traits that may be more accessible to genetic dissection than clinical CVD end points. Chromosome 19 harbors multiple genes that have been suggested to play a role in lipid metabolism and previous studies indicated the presence of a quantitative trait locus (QTL) for cholesterol levels in genetic isolates. To establish the relevance of genetic variation at chromosome 19 for plasma levels of lipids and apolipoproteins in the general, out-bred Caucasian population, we performed a linkage study in four independent samples, including adolescent Dutch twins and adult Dutch, Swedish and Australian twins totaling 493 dizygotic twin pairs. The average spacing of short-tandem-repeat markers was 6 - 8 cM. In the three adult twin samples, we found consistent evidence for linkage of chromosome 19 with LDL cholesterol levels ( maximum LOD scores of 4.5, 1.7 and 2.1 in the Dutch, Swedish and Australian sample, respectively); no indication for linkage was observed in the adolescent Dutch twin sample. The QTL effects in the three adult samples were not significantly different and a simultaneous analysis of the samples increased the maximum LOD score to 5.7 at 60 cM pter. Bivariate analyses indicated that the putative LDL-C QTL also contributed to the variance in ApoB levels, consistent with the high genetic correlation between these phenotypes. Our study provides strong evidence for the presence of a QTL on chromosome 19 with a major effect on LDL-C plasma levels in outbred Caucasian populations.

Voice and speech characteristics and vocal hygiene in novice and professional voice broadcast journalists

Knowledge of differences in voice and speech characteristics between novice and professional broadcasters is essential for effective education of broadcast journalism students. Because newsreaders rely on optimal voice production, information pertaining to vocal hygiene is also important. The first aim of this study was to compare the voice and speech characteristics of professional newsreaders, student newsreaders and control participants. The second aim was to compare the awareness and use of vocal hygiene across these groups. Professional radio newsreaders, broadcast journalism students and two matched control groups were included in the study. Each participant recorded a news bulletin and completed a questionnaire on vocal hygiene. Data analysis of the recording included objective analysis and perceptual ratings by a panel of three judges. Significant student-professional differences were found. Compared to both the students and the control groups, the professional newsreaders had greater variation in speaking fundamental frequency, a faster rate of speech, fewer pronunciation errors and higher perceptual ratings on vocal quality, emphasis, continuity, phrasing and style of newsreading. Female professional newsreaders had a higher speaking fundamental frequency than both their control participants and the student newsreaders. Comparison of vocal hygiene awareness revealed few significant differences between any of the groups.

Pensando o currículo com as crianças: ou sobre aprendizagens inventivas na educação infantil

Ninguém consegue sair ileso de um encontro com o currículo e com a escola, principalmente diante de relações tão assimétricas de poder que não valorizam o que as crianças têm a dizer. Quantas narrativas curriculares sobre as crianças? Quantas narrativas curriculares com as crianças? As narrativas e as fotografias se seguirão nesta pesquisa, porque com elas nos colocamos a pensar nos processos de criação curricular, explorando novas sensibilidades, novas maneiras de ver e falar, a partir das redes de sentidos, forjadas nos contextos vividos, imaginados ou pensados, dentrofora da escola. Também incluímos a forma como as crianças se relacionam com as práticas pedagógicas dos professores e do modo como se relacionam com a escola. Nessa perspectiva, interessa-nos pensar em como os usos (CERTEAU, 1994) da imagem fotográfica são capazes de afetar (e até transformar) as práticas curriculares, traçando algo da potência da/na imagem fotográfica em sua função fabuladora por meio das oficinas de fotografias realizadas com as crianças em virtude da pesquisa. A fotografia se torna potente como um recurso para provocar a invenção tessitura de outros sentidos em currículo não porque em sua materialidade ela está repleta de sentidos de currículo à priori, mas porque pode ou não, ao ser usada (CERTEAU, 1994), ao ser vista pelas crianças, agenciar outros possíveis para o currículo. Assim, o foco da discussão não é a fotografia em si nem a criança em si, ou seja, não há protagonismo nem da criança nem da fotografia. O foco está nas relações, naquilo que nos passa, isto é, na experiência estética (LARROSA, 2004b) que ocorre ao entrarmos em contato, ao vermos, ao compormos com as fotografias! Nesse sentido, pensamos as oficinas de fotografias como um dispositivo de criação e produção de acontecimentos em currículo, considerando-as máquinas de fazer “ver e falar”, o que as justifica como uma estratégia narrativa capaz de produzir acontecimentos na imagem e no mundo. Que sentidos de currículo são produzidos em multiplicidades? Pelas minoridades pretendemos movimentar nosso pensamento: que quer pensar um currículo como fabulação sem dizer o que ele é, mas no que ele vai se transformando com a chegada das crianças. No encontro das imagens com as palavras, em que o currículo vai se transformando? Sob a mesma superfície chamada currículo em extensão com as crianças, co-habitantes, encontrar os modos de olhar esse currículo e de dizê-lo por meio das fotografias, das narrativas, dos cartazes, dos desenhos, das poesias... As conversas com as crianças provocam o real, colocam em desequilíbrio algumas ideias feitas em educação, exigindo reordenações e invenções de outros pensamentos para a educação. É dessa criação de efeitos impensáveis que surge a invenção de currículos possíveis. Aprender a olhar mais (até cansar!) aquilo que não percebemos no dia a dia tem uma dimensão política muito importante; por meio desse gesto (que aprendemos com as crianças) podemos criar um novo pensamento político em educação. A partir daquilo que nos dá a ver, as crianças vão inaugurar sentidos impertinentes, desestabilizadores daquilo que chamamos de currículo e escola. O desafio consiste em falar da força contida na imagem fotográfica sem vontade de interpretá-la ou descrevê-la, mas escrever e pensar pelas fotografias num movimento de criação de sentidos e acontecer por elas.

Lucidez-Embriaguez, movimento e arrebatamento: homens,(Semi)deuses que perambulam e a educação menor num bairro de uma rede municipal

A tese afirma a vida por meio das biopotências que se manifestam em movimentações invisíveis aos olhos acostumados a permitir o ver, o julgar e o falar. Foca o tempo presente, na comunicação em redes, traz em si a potência de reatar a multidão, com a capacidade de sondar possibilidades mostrando o que antes parecia opaco e impossível. Perambular é ligar nas redes quentes de um bairro com/no/do território ao privilegiar o movimento, o processo, sempre caminhando pelas vias e conexões abertas, aposta estética-ética-política nos paradoxos sem superação e não hierarquizados. Toma como método de pesquisa-intervenção elementos de uma cartografia de movimentos e devires, traçando um perambular rizomático em que são problematizados a constituição do problema de pesquisa, que considera a construção do conhecimento diversificada, descentralizada e horizontalizada. Problematiza as práticas discursivas de si em suas relações com a biopolítica, a governabilidade e a biopolítica das populações. O que está(rá) rolando nesse bairro, no que foi chamado de criança, adolescente, escola, compor para que as coisas apareçam, junto com outros que vivem a loucura em duplas e trios. A tese é a possibilidade da existência de uma educação menor na periferia para as populações marginalizadas, muçulmanizadas. Educação menor, da sala de aula, do bairro, do cotidiano de professores, familiares e alunos. Educação que permite revolucionários, na medida em que alguma revolução ainda faz sentido na educação nesses dias. A educação menor constitui-se, assim, num empreendimento de militância, de professores militantes. Plano das afecções em que não há unidades, apenas intensidade. A tese fala do processo, de como reproduzir, ou não, os modos de subjetividade dominante, não se trata de medidas - "menor" ou "pequeno". Nesse sentido, é preciso considerar os efeitos de produção de subjetividade e a incorporação dos fatos à própria vida. A tese analisa movimentos instituintes buscando reconhecê-los em sua natureza contestatória e transgressora e ter conhecimento de como se organiza na escola e muito além dela. Discutindo a produtividade dessa coreografia do perambular, esboçamos movimentos que denominamos: estradas que levam a nada, além muro

A intensificação do trabalho docente no processo de financeirização da educação superior : o caso da Kroton no Estado do Espírito Santo

O estudo teve por objetivo investigar, a partir de duas instituições de ensino superior pertencentes ao grupo Kroton no Espírito Santo, o impacto das mudanças trazidas para o trabalho docente decorrente do processo de inserção da educação superior na Bolsa de Valores. Essas instituições são a Faculdade Pitágoras de Guarapari e a Faculdade Pitágoras de Linhares. Até 2007, juridicamente, essas instituições eram sociedades limitadas e não pertenciam ao grupo Kroton. Eram conhecidas como Faculdades Integradas Padre Anchieta de Guarapari (Fipag) e Faculdade de Ciências Aplicadas Sagrado Coração (Unilinhares), respectivamente. Em 2008, a Kroton adquire essas duas faculdades e começa a operá-las a partir da marca Pitágoras. Portanto, esta pesquisa consiste em um estudo de caso das unidades Pitágoras localizadas no Estado do Espírito Santo. Busca compreender, fundamentada em entrevista semiestruturada com 12 professores e ex-professores, como eram a organização e as condições do trabalho docente antes de essas instituições serem adquiridas pela Kroton e o que mudou após sua aquisição. Para a realização da análise teórica, a pesquisa se apoiou em Karl Marx, François Chesnais e Dermeval Saviani. Ao final, a hipótese de que, após a aquisição da Fipag e da Unilinhares pela Kroton, houve uma intensificação da exploração do trabalho docente e uma redução da autonomia do professor no que concerne às atividades de planejamento e ensino foi confirmada: pelo excessivo acréscimo de trabalho (Termo e Aula Estruturada); pela diversidade de disciplinas a que o professor esteve sujeito a ministrar; pelo regime de tensão que balizou a organização do trabalho (aumento das demissões); pela exclusão da participação do professor na escolha do referencial teórico e metodológico. Em parte, esses aspectos são fruto da combinação do taylorismo com a governança corporativa e atuaram de forma a reduzir a participação do professor nas atividades ligadas ao planejamento e ensino, reforçando, com isso, as relações sociais de dominação inerentes ao trabalho alienado.
