Social competence and peer interactions of students with intellectual disability in an inclusive high school

This paper reports descriptive information on the relationship between social competence and the amount and type of peer interaction for nine adolescents with intellectual disability attending a regular high school. Each adolescent's social competence was assessed using the AAMR Adaptive Behavior Scale-School (2nd edn) (ABS-S:2). Naturalistic observations were conducted to obtain information on the amount and type of peer interaction. Data were analysed to determine the relationship between social competence and peer interactions. Social competence was not consistently correlated with the amount of peer interaction. Results from the naturalistic observations showed individual differences in patterns of peer interaction with a tendency towards more frequent interactions with peers who also had intellectual disabilities. These data suggest that social competence did not significantly influence the amount and type of peer interaction. Implications for facilitating peer interactions between adolescents with and without intellectual disability are discussed.

The competence of mental health occupational therapists

This research sought to investigate the self-perceived competence of mental health occupational therapists in Queensland. The research is a post-hoc analysis of survey results that formed part of the 1995 Professional Development Strategy for Adult Mental Health Services for the Queensland Health Mental Health Unit. A sample of 55 occupational therapists was compared with other professionals in relation to both general self-efficacy and efficacy in specific competencies. The devised scale for measuring self-efficacy was found to have a high level of internal reliability. The results indicated that the general self-perceived competence of occupational therapists for the whole sample was comparable to that of other professional groups, but that in the community-based sample it was significantly higher than that of social workers or nurses. In addition, occupational therapists in community settings had significantly higher general self-perceived competence than occupational therapists in hospital locations. Greater length of experience in mental health was strongly predictive of higher levels of competence for occupational therapists than for other professionals. The results suggest that occupational therapists have adapted well to the demands of multidisciplinary community practice. The possible reasons for these results, and the implications for competency-based recruitment and training, are presented.

Vector competence of Coquillettidia linealis (Skuse) (Diptera : Culicidae) for Ross River and Barmah Forest viruses

Coquillettidia linealis is a severe pest on some of the Moreton Bay islands in Queensland, Australia, but little is known of its breeding habitats and biology. Because of its high abundance and its association with Ross River (RR) and Barmah Forest (BF) viruses by field isolation, its vector competence was evaluated in the laboratory by feeding dilutions of both viruses in blood. For RR, Cq. linealis was of comparable efficiency to Ochlerotatus vigilax (Skuse), recognised as being a major vector. Results were as follows for Cq. linealis and Oc. vigilax , respectively: dose to infect 50%, 10(2.2) and

Enhancement or modulation of the vector competence of ochlerotatus vigilax (Diptera : Culicidae) for Ross River virus by temperature

Two different doses of Ross River virus (1111) were fed to Ochlerotatus vigilax (Skuse), the primary coastal vector in Australia; and blood engorged females were held at different temperatures up to 35 d. After ingesting 10(4.3) CCID50/Mosquito, mosquitoes reared at 18 and 25degreesC (and held at the same temperature) had higher body remnant and head and salivary gland titers than those held at 32degreesC, although infection rates were comparable. At 18, 25, and 32degreesC, respectively, virus was first detected in the salivary glands on days 3, 2, and 3. Based on a previously demonstrated 98.7% concordance between salivary gland infection and transmission, the extrinsic incubation periods were estimated as 5, 4, and 3 d, respectively, for these three temperatures. When Oc. vigilax reared at 18, 25, or 32degreesC were fed a lower dosage of 10(3.3) CCID50 RR/mosquito, and assayed after 7 d extrinsic incubation at these (or combinations of these) temperatures, infection rates and titers were similar. However, by 14 d, infection rates and titers of those reared and held at 18 and 32degreesC were significantly higher and lower, respectively. However, this process was reversible when the moderate 25degreesC was involved, and intermediate infection rates and titers resulted. These data indicate that for the strains of RR and Oc. vigilax used, rearing temperature is unimportant to vector competence in the field, and that ambient temperature variations will modulate or enhance detectable infection rates only after 7 d: extrinsic incubation. Because of the short duration of extrinsic incubation, however, this will do little to influence RR epidemiology, because by this time some Oc. vigilax could be seeking their third blood meal, the latter two being infectious.

Assessing childrens competence in computer interactions: Preliminary reliability and validity of the test of mouse proficiency

The Test of Mouse Proficiency (TOMP) was developed to assist occupational therapists and education professionals assess computer mouse competency skills in children from preschool to upper primary (elementary) school age. The preliminary reliability and validity of TOMP are reported in this paper. Methods used to examine the internal consistency, test-retest reliability, and criterion- and construct-related validity of the test are elaborated. In the continuing process of test refinement, these preliminary studies support to varying degrees the reliability and validity of TOMP. Recommendations for further validation of the assessment are discussed along with indications for potential clinical application.

Enhanced vector competence of Aedes aegypti (Diptera : Culicidae) from the torres strait compared with mainland Australia for dengue 2 and 4 viruses

Australian Aedes aegypti (L.) mosquitoes colonized from the Torres Strait and three mainland localities (Charters Towers, Townsville, and Cairns) were fed on blood suspensions containing dengue virus type 2 (DEN-2) or dengue virus type 4 (DEN-4). Variation was found in oral susceptibility to DEN-2 (59-99% infection) and DEN-4 (28-79% infection) among Ae. aegypti assayed for virus at 8, 12, 16, or 20 d after ingestion of infected blood. Torres Strait Ae. aegypti were the most susceptible to DEN-2 and were significantly more efficient in transmission to capillary tube at 16 d (76% transmission) than mainland Ae. aegypti populations (20-28% transmission). Torres Strait Ae. aegypti were also the most susceptible to DEN-4, although transmission did not vary significantly from mainland populations at 16 d (12% compared with 0-4%) or 20 d (16% compared with 4-16%). Disseminated infection (i.e., leg infection) with either DEN-2 or DEN-4 was not an accurate predictor of transmission potential. This study demonstrates differences among Australian Ae. aegypti populations in vector competence for DEN-2 and DEN-4. Torres Strait Ae. aegypti were more frequently infected and able to transmit DEN-2 at higher rates than mainland populations. These data indicate that the Torres Strait region is potentially more receptive to dengue transmission than mainland localities, a finding discussed with respect to past outbreaks.

Vector competence of Australian mosquitoes (Diptera : Culicidae) for Japanese encephalitis virus

Australian mosquitoes were evaluated for their ability to become infected with and transmit a Torres Strait strain of Japanese encephalitis virus. Mosquitoes, which were obtained from either laboratory colonies and collected using Centers for Disease Control and Prevention light traps baited with CO2 and octenol or reared from larvae, were infected by feeding on a blood/sucrose solution containing 10(4.5+/-0.1) porcine stable-equine kidney (PS-EK) tissue culture infectious dose(50)/ mosquito of the TS3306 virus strain. After 14 d, infection and transmission rates of 100% and 81%, respectively, were obtained for a southeast Queensland strain of Culex annulirostris Skuse, and 93% and 61%, respectively, for a far north Queensland strain. After 13 or more days, infection and transmission rates of > 90% and greater than or equal to 50%, respectively, were obtained for southeast Queensland strains of Culex sitiens Wiedemann and Culex quinquefasciatus Say, and a far north Queensland strain of Culex gelidus Theobald. Although infection rates were > 55%, only 17% of Ochlerotatus vigilax (Skuse) and no Cx. quinquefasciatus, collected from far north Queensland, transmitted virus. North Queensland strains of Aedes aegypti L., Ochlerotatus kochi (Donitz), and Verrallina funerea (Theobald) were relatively refractory to infection. Vertical transmission was not detected among 673 F, progeny of Oc. vigilax. Results of the current vector competence study, coupled with high field isolation rates, host feeding patterns and widespread distribution, confirm the status of Cx. annulirostris as the major vector of Japanese encephalitis virus in northern Australia. The relative roles of other species in potential Japanese encephalitis virus transmission cycles in northern Australia are discussed.

The egalitarian leader: A comparison of leadership in Australia and New Zealand

This article compares leadership in Australia and New Zealand based on data collected as a part of the GLOBE (Global Leadership and Organizational Behavior effectiveness) 62-nation culture and leadership project. Exploratory and confirmatory factor analyses were used to demonstrate that etic (universal) dimensions of 'Charismatic' and 'Self-Protective' leadership are evident in both cultures, but that the dimensions have emic (local) culturally determined manifestations. These emic manifestations were stronger in New Zealand than in Australia. Leadership effectiveness incorporated the negative emic dimension of 'Bureaucratic' leadership (both countries), and the positive emic dimension of 'Egalitarian leadership' in Australia and 'Team leadership' in New Zealand. Both models of leadership nonetheless represent styles of leadership based on egalitarian principles.

A retrospective analysis of leadership development through sport

The purpose of this study was to examine the development of six leader-athletes. In-depth qualitative interviews were used to explore the various activities that leader athletes engaged in from an early age as well as the roles and influences that peers, coaches, and parents played within these activities. Results indicated that leadership development in sport focused on developing four central components: high skill, strong work ethic, enriched cognitive sport knowledge, and good rapport with people. The types of activities engaged in throughout development as well as receiving feedback, acknowledgement, support, cognitive engagement, mature conversations with adults, and physical encounters with older peers are important social influences that can play an instrumental role in the formation of these four central tenets.

Vector competence experiments with Rocio virus and three mosquito species from the epidemic zone in Brazil

First-generation progeny of field-collected Psorophora ferox, Aedes scapularis, and Aedes serratus from the Rocio encephalitis epidemic zone in S.Paulo State, Brazil, were tested for vector competency in the laboratory. Psorophora ferox and Ae. scapularis are susceptible to per os infection with Rocio virus and can transmit the virus by bite following a suitable incubation period. Oral ID50S for the two species (10(4.1) and 10(4.3) Vero cell plaque forming units, respectively) did not differ significantly. Infection rates in Ae. serratus never exceeded 36%, and, consequently, an ID50 could not be calculated for this species. It is unlikely that Ae. serratus is an epidemiologically important vector of Rocio virus. The utility of an in vitro feeding technique for demonstrating virus transmission by infected mosquitoes and difficulties encountered in working with uncolonized progeny of field-collected mosquitoes are discussed.

Looking the organization's "backstages": political leadership in health organizations

Although leadership investigation has become for the last years an election topic with major relevance on organizational studies and accepting peacefully the general idea that organizations are freeland for politics, all these acceptances run against a kind of “fear” from the academy scholars on approaching the political leaderships’ singularities on organizations. Indeed, when we cross over both phenomena we verify that the absence and weaknesses towards the unique characteristics of political leadership on work scenarios are becoming sharped regarding to their predictors, their workers and their organizations, even if we left aside its moderator variables.
