Objectives: To determine the effects of gender on mental health literacy in young people between 12 and 25 years of age. Design: Computer-Assisted Telephone Interviewing was employed to conduct a cross-sectional structured interview focusing on young people's awareness of depression and psychosis. Participants: The sample comprised 1207 young Australians (539 males and 668 females) between the ages of 12-25 recruited from two metropolitan and two regional areas within Victoria. Six hundred and six respondents were presented a depression vignette and 601 were presented a psychosis vignette. Results: Female respondents (60.7%) were significantly more likely to correctly identify depression in the vignette as compared to male respondents (34.5%). No significant gender differences were noted for the psychosis vignette. Males were less significantly likely to endorse seeing a doctor or psychologist/counsellor for the treatment of psychosis. Males were also significantly more likely than females to endorse alcohol as a way of dealing with depression and antibiotics as useful for dealing with psychosis. Conclusion: Gender differences in mental health literacy are striking. Males showed significantly lower recognition of symptoms associated with mental illness and were more likely endorse the use alcohol to deal with mental health problems. Such factors may contribute to the delays in help seeking seen in young males. Further research is needed to delineate how these gender differences in young people may obstruct help seeking, early intervention and other aspects of mental health service delivery.

Objective: This study examined the validity of a model predicting weight restricting behaviour both cross-sectionally and longitudinally. Method: Participants comprised 1207 girls aged from 12 to 14 years. The girls completed self-report questionnaires at three time points over 1-year intervals. Results: The cross-sectional results suggested that weight preoccupation and body dissatisfaction directly predicted weight restricting behaviour. In addition, upset induced by teasing, depressive symptoms, BMI and negative attributional style demonstrated indirect effects on weight restricting behaviour through their effects on body dissatisfaction and/or weight preoccupation. Longitudinally however, only weight restricting behaviour and body dissatisfaction were significant in the prediction of weight restricting behaviour. Discussion: The implications of the results are discussed, together with suggestions for future research. Copyright (c) 2006 John Wiley & Sons, Ltd and Eating Disorders Association.

O presente estudo avaliou as dimensões transversais dos arcos dentais mandibulares em indivíduos com diferentes padrões faciais. A amostra foi constituída por telerradiografias em norma lateral direita e modelos em gesso de 33 indivíduos, leucodermas, em ambos os sexos, com idade entre 13 e 25 anos, na fase de dentição permanente. O Padrão Facial foi obtido pela análise facial subjetiva em fotografias frontal e de perfil de 1500 documentações ortodonticas, foi utilizada análise cefalométrica por meio do ângulo ANB para confirmar o padrão esquelético, o qual deveria coincidir com a classificação de maloclusão de Angle. A amostra foi dividida em três grupos: Grupo I Padrão I, Classe I de Angle e ANB 2,0 o ±0,5o; Grupo II Padrão II, Classe II divisão 1 de Angle e ANB ≥ 4,0, e Grupo III Padrão III, Classe III de Angle e ANB ≥ - 4,5o. As dimensões transversais do arco foram mensuradas após a digitalização dos modelos em gesso pelo Scanner Dental Wings (3D), a partir dos quais foram estabelecidas as distâncias transversais intercanino, inter 1º PM, inter 2º PM, inter 1º M (cúspide mesial e distal), inter 2º M (cúspide mesial e distal), com o auxílio do software Geomagic Studio® 12. As médias e desvio padrão das dimensões transversais foram obtidas, e, para comparação entre os três grupos foi utilizado a Análise de Variância e teste de Tukey. Em todos os testes estatísticos foi adotado nível de significância de 5% (p<0,05). Houve diferença estatística em duas dimensões transversais das 14 avaliadas no arco maxilar na região mesial do segundo molar (p=0,024) e no mandibular na região distal do primeiro molar (p=0,047). Os arcos dentais mandibulares foram semelhantes nos três grupos estudados.

O presente documento é um relatório da atividade profissional realizada no Clube Naval do Funchal (CNF) e insere-se no âmbito do mestrado em Atividade Física e Desporto, realizado enquanto aluno da Universidade da Madeira, focado sobre o desempenho, ações, funções e demais iniciativas levadas a cabo nos últimos cinco anos no CNF, tendo como tema principal a “Vela Adaptada” (VA) no CNF. Esta análise e reflexão crítica ao trabalho desenvolvido serão suportadas através das experiências e vivências próprias. A vela adaptada é um desporto recente na cena nacional e regional. Nos dias de hoje, a responsabilidade humana e social de cada um de nós determina que tenhamos o dever ético e moral de criar condições de inclusão às pessoas portadoras de deficiência, possibilitando e facilitando a superação de barreiras sociais que estão enraizadas em todos nós, bem como ajudando à mitigação dos constrangimentos no seu dia a dia. Por essa via, melhoramos a sua qualidade de vida e conferimos-lhes maior autonomia, sendo a atividade física adaptada uma das formas possíveis. Este desporto adaptado tem crescido nos últimos anos, fruto do surgimento de meios tecnológicos apropriados, digam-se embarcações que oferecem todas as garantias de sucesso no ensino aprendizagem desta variante da vela. Desta forma, a inclusão social e o desenvolvimento da vela adaptada oferecem e possibilitam a realização de atividades físicas de forma mais corrente, normal e, acima de tudo, segura. Este trabalho é um exemplo do papel social e inclusivo feito através da implementação de um desporto náutico, neste caso da vela adaptada, como forma de minimizar as assimetrias existentes neste âmbito social.

Ten cases of neuronal intermediate filament inclusion disease (NIFID) were studied quantitatively. The α-internexin positive neurofilament inclusions (NI) were most abundant in the motor cortex and CA sectors of the hippocampus. The densities of the NI and the swollen achromatic neurons (SN) were similar in laminae II/III and V/VI but glial cell density was greater in V/VI. The density of the NI was positively correlated with the SN and the glial cells. Principal components analysis (PCA) suggested that PC1 was associated with variation in neuronal loss in the frontal/temporal lobes and PC2 with neuronal loss in the frontal lobe and NI density in the parahippocampal gyrus. The data suggest: 1) frontal and temporal lobe degeneration in NIFID is associated with the widespread formation of NI and SN, 2) NI and SN affect cortical laminae II/III and V/VI, 3) the NI and SN affect closely related neuronal populations, and 4) variations in neuronal loss and in the density of NI were the most important sources of pathological heterogeneity. © Springer-Verlag 2005.

The kinematic mapping of a rigid open-link manipulator is a homomorphism between Lie groups. The homomorphisrn has solution groups that act on an inverse kinematic solution element. A canonical representation of solution group operators that act on a solution element of three and seven degree-of-freedom (do!) dextrous manipulators is determined by geometric analysis. Seven canonical solution groups are determined for the seven do! Robotics Research K-1207 and Hollerbach arms. The solution element of a dextrous manipulator is a collection of trivial fibre bundles with solution fibres homotopic to the Torus. If fibre solutions are parameterised by a scalar, a direct inverse funct.ion that maps the scalar and Cartesian base space coordinates to solution element fibre coordinates may be defined. A direct inverse pararneterisation of a solution element may be approximated by a local linear map generated by an inverse augmented Jacobian correction of a linear interpolation. The action of canonical solution group operators on a local linear approximation of the solution element of inverse kinematics of dextrous manipulators generates cyclical solutions. The solution representation is proposed as a model of inverse kinematic transformations in primate nervous systems. Simultaneous calibration of a composition of stereo-camera and manipulator kinematic models is under-determined by equi-output parameter groups in the composition of stereo-camera and Denavit Hartenberg (DH) rnodels. An error measure for simultaneous calibration of a composition of models is derived and parameter subsets with no equi-output groups are determined by numerical experiments to simultaneously calibrate the composition of homogeneous or pan-tilt stereo-camera with DH models. For acceleration of exact Newton second-order re-calibration of DH parameters after a sequential calibration of stereo-camera and DH parameters, an optimal numerical evaluation of DH matrix first order and second order error derivatives with respect to a re-calibration error function is derived, implemented and tested. A distributed object environment for point and click image-based tele-command of manipulators and stereo-cameras is specified and implemented that supports rapid prototyping of numerical experiments in distributed system control. The environment is validated by a hierarchical k-fold cross validated calibration to Cartesian space of a radial basis function regression correction of an affine stereo model.

The relationship between theory and practice has been discussed in the social sciences for generations. Academics from management and organization studies regularly lament the divide between theory and practice. They regret the insufficient academic knowledge of managerial problems and their solutions, and criticize the scholarly production of theories that are not relevant for organizational practice (Hambrick 1994). Despite the prevalence of this topic in academic discourse, we do not know much about what kind of academic knowledge would be useful to practice, how it would be produced and how the transfer of knowledge between theory and practice actually works. In short, we do not know how we can make academic work more relevant for practice or even whether this would be desirable. In this introduction to the Special Issue, we apply philosophical, theoretical and empirical perspectives to examine the challenges of studying the generation and use of academic knowledge. We then briefly describe the contribution of the seven papers that were selected for this Special Issue. Finally, we discuss issues that still need to be addressed, and make some proposals for future avenues of research.

While commitment is an important antecedent to customer retention, a broad consensus has yet to emerge on the impacts of constituent dimensions of commitment on loyalty in service relationships. This study explores the impacts of affective and continuance commitment on attitudinal and behavioral loyalty in a service context. Since affective commitment is more positive and governed by free choice, whereas continuance commitment is more the result of perceived economic and psychological benefits of being in a relationship, the results of this study suggest that emotional bonds with customers provide a more enduring source of loyalty as compared to economic incentives and switching costs.

We present a novel approach to the improvement of the bit error rate (BER) in optical communications. We propose a design of advanced optical receiver enhanced by a nonlinear all-optical decision element. As a particular example, we demonstrate a substantial improvement in the BER over the conventional receiver for operation at 40?Gbits/s.

We demonstrate experimentally a novel and simple tunable all-optical incoherent negative-tap fiber-optic transversal filter based on a distribution feedback laser diode and high reflection fiber Bragg gratings (FBGs). In this filter, variable time delay is provided by cascaded high reflection fiber Bragg gratings (FBGs), and the tuning of the filter is realized by tuning different FBG to match the fixed carrier wavelength, or adjusting the carrier wavelength to fit different FBG. The incoherent negative tapping is realized by using the carrier depletion effect in a distribution feedback laser diode.
