A brachiopod fauna including 19 species of 17 genera from an exotic block in the Indus–Tsangpo suture zone in southern Tibet is described and illustrated. The brachiopod fauna is dominated by Martinia elegans and two new taxa: Jinomarginifera lhazeensis gen. et sp. nov. and Zhejiangospirifer giganteus sp. nov. The fauna is closely comparable with those from the middle and upper parts of the Wargal Formation and the Chhidru Formation in the Salt Range of Pakistan, the Chitichun Limestone in southern Tibet, and the Basleo area of West Timor, and these correlations suggest a Wuchiapingian age. The fauna exhibits substantial links with both peri–Gondwanan and Cathaysian faunas, which may imply that it is a seamount biota originally located in the southern margin of the Neotethys during the Late Permian, and was later (in the early Cenozoic) displaced and became sandwiched into younger marine deposits in the collision process between India and Eurasia.

The Late Caledonian to Early Hercynian North Qilian orogenic belt in northwestern China is an elongate tectonic unit situated between the North China plate in the north and the Qaidam plate in the south. North Qilian started in the latest Proterozoic to Cambrian as a rift basin on the southern margin of North China, and evolved later to an archipelagic ocean and active continental margin during the Ordovician and a foreland basin from Silurian to the Early and Middle Devonian. The Early Silurian flysch and submarine alluvial fan, the Middle to Late Silurian shallow marine to tidal flat deposits and the Early and Middle Devonian terrestrial molasse are developed along the corridor Nanshan. The shallowing-upward succession from subabyssal flysch, shallow marine, tidal flat to terrestrial molasse and its gradually narrowed regional distribution demonstrate that the foreland basin experienced the transition from flysch stage to molasse stage during the Silurian and Devonian time.

To compare the work practices and training needs of rural and urban psychologists, 774 surveys were sent to psychologists throughout Australia. The psychologists were selected from the Australian Psychological Society (APS) Directory of Psychologists, 1992- 1993. A total of 86 rural psychologists and 282 urban psychologists responded to the survey. The survey comprised of four sections with questions asking respondents their demographic and employment background, past and current training activities, work experience, and relations with community. Results showed that the decision to practice and remain in a rural area was influenced by psychologists’ childhood experience and professional training in a rural setting, A substantial proportion of rural psychologists (28%) had been working in rural practice for five years or less. These rural psychologists were identified as a group that had a demographic and training profile more similar to urban psychologists than their rural colleagues. The employment conditions and training background of rural and urban psychologists were similar, though rural psychologists were more likely to be working in private practice and have undertaken their studies in a rural setting. Rural and urban psychologists rated their undergraduate and postgraduate training in psychology as only somewhat adequate. Training in rural health and community issues received the lowest ratings from both groups of psychologists. The work practices of rural and urban psychologists were also similar. There were some differences in the demographic profile of the client groups seen by the two groups. Rural psychologists reported the type of relations with their communities that are conducive to rural practice. The main evidence of this was that rural psychologists were collaborating with the natural helpers of their communities, and expressed willingness to formally train natural helpers to assist in the provision of psychological services. There were several conclusions drawn from this study. The first conclusion was that rural psychologists with urban demographic and training backgrounds are a group that is likely to migrate from rural practice to urban practice, Secondly, training needs to be specialised for rural practice if there is to be an improvement in the number of psychologists practicing in rural settings. Thirdly, rural psychologists were conducting the type of relations with their communities that are important to the requirements of rural practice.

Partnering early childhood education and care (ECEC) and the home together may be more effective in combating obesogenic risk factors in preschool children. Thus, an evaluation of ECEC obesity prevention interventions with a parental component was conducted, exploring parental engagement and its effect on obesity and healthy lifestyle outcomes. A search revealed 15 peer-reviewed papers. Some studies demonstrated positive weight changes, and secondary outcomes of changes in physical activity and healthy eating were reported in most studies; study quality ranged from fair to good. Four findings were linked to weight changes: (1) when educational material is consistent across settings; (2) capacity building of parents; (3) parents encouraging their children to drink water and (4) parental satisfaction and participation. A partnership between parents and ECEC may be a powerful force in the prevention of paediatric obesity. A better understanding of collaborative parental engagement is needed.

Accessible health services are those that are physically available, affordable (economic accessibility), appropriate and acceptable. Health services can be inaccessible if providers do not acknowledge and respect cultural factors, physical barriers and economic barriers, or if the community is not aware of available services.There are many strategies for successfully improving Indigenous access to urban and regional health services. Individual service providers need to consult with their local community to identify the specific issues relating to their context and selectively adapt the strategies outlined in this report.

The Internet has provided an ever increasingly popular platform for individuals to voice their thoughts, and like-minded people to share stories. This unintentionally leaves characteristics of individuals and communities, which are often difficult to be collected in traditional studies. Individuals with autism are such a case, in which the Internet could facilitate even more communication given its social-spatial distance being a characteristic preference for individuals with autism. Previous studies examined the traces left in the posts of online autism communities (Autism) in comparison with other online communities (Control). This work further investigates these online populations through the contents of not only their posts but also their comments. We first compare the Autism and Control blogs based on three features: topics, language styles and affective information. The autism groups are then further examined, based on the same three features, by looking at their personal (Personal) and community (Community) blogs separately. Machine learning and statistical methods are used to discriminate blog contents in both cases. All three features are found to be significantly different between Autism and Control, and between autism Personal and Community. These features also show good indicative power in prediction of autism blogs in both personal and community settings.

Foram coletadas 143 amostras de mãos de humanos e camas hospitalares, através de swabs no caldo BHI, em um hospital escola da cidade de Ribeirão Preto/SP. As amostras coletadas foram incubadas a 37ºC por 24 horas e após este período as culturas foram semeadas em placas de Petri contendo agar Staphylococcus Médium 110. As colônias típicas do gênero Staphylococcus foram colhidas e estocados a 4ºC até o momento de elaboração das provas de catalase, manitol, hemólise, DNAse e coagulase. As cepas isoladas foram analisadas através da técnica de RAPD-PCR para verificar o grau de similaridade. A sensibilidade das cepas isoladas foi testada frente a 10 diferentes antibióticos. Das 92 cepas de Staphylococcus sp isoladas, 67 (72,8%) foram identificados como Staphylococcus coagulase-negativas e 25 (27,2%) como Staphylococcus coagulase-positivas. A análise de similaridade mostrou uma grande heterogeneidade entre as cepas, entretanto foram isoladas algumas cepas com 100% de similaridade. Resistência a oxacilina foi encontrada em 39 (42%) cepas. Duas cepas de estafilococos coagulase-negativos mostraram-se resistentes a vancomicina. Onze cepas (12%) de estafilococos foram consideradas multirresistentes. Medidas de desinfecção das mãos de pessoal e dos leitos hospitalares e a racionalização do uso indiscriminado de antibióticos podem contribuir para a queda da transmissão de patógenos e diminuição da pressão de seleção, e conseqüentemente diminuindo a freqüência e letalidade das infecções nosocomiais.
