School Bullying Prevention Task Force report /

The Task Force was charged with exploring the causes and consequences of bullying in schools in this State, identifying promising practices that reduce incidences of bullying, highlighting training and technical assistance opportunities for schools to effectively address bullying, evaluating the effectiveness of schools current anti-bullying policies and other bullying prevention programs, and other related issues. Under tight time constraints, the Task Force has met that change. The Illinois State Board of Education will post this report on its webpage devoted to the Task Force (http://www.isbe.net/SBPTF/default.htm). Moreover in the near future, the Task Force will produce an Executive Summary of this report which the ISBE will also include on the Task Force webpage.

On being loud and proud: Non-conformity and counter-conformity to group norms

Most experiments on conformity have been conducted in relation to judgments of physical reality; surprisingly few papers have experimentally examined the influence of group norms on social issues with a moral component. In response to this, participants were told that they were either in a minority or in a majority relative to their university group in terms of their attitudes toward recognition of gay couples in law (Expt 1: N = 205) and a government apology to Aborigines (Expt 2: N = 110). In both experiments, it was found that participants who had a weak moral basis for their attitude conformed to the group norm on private behaviours. In contrast, those who had a strong moral basis for their attitude showed non-conformity on private behaviours and counter-conformity on public behaviours. Incidences of nonconformity and counter-conformity are discussed with reference to theory and research on normative influence.

A comparison of the efficacy and safety of olanzapine versus haloperidol during transition from intramuscular to oral therapy

Background: Acutely agitated patients with schizophrenia who receive intramuscular (IM) medications typically are switched to oral (PO) antipsychotic maintenance therapy Objective: The goal of this study was to assess the efficacy and safety of olanzapine versus those of haloperidol during transition from IM to PO therapy We used additional data from a previously reported trial to test the hypothesis that the reduction in agitation achieved by IM olanzapine 10 mg or IM haloperidol 7.5 mg would be maintained following transition to 4 days of PO olanzapine or PO haloperidol (5-20 mg/d for both). We also hypothesized that olanzapine would maintain its more favorable extrapyramidal symptom (EPS) safety profile. Methods: This was a multinational (hospitals in 13 countries), double-blind, randomized, controlled trial. Acutely agitated inpatients with schizophrenia were treated with 1 to 3 IM injections of olanzapine 10 mg or haloperidol 7.5 mg over 24 hours and were entered into a 4-day PO treatment period with the same medication (5-20 mg/d for both). The primary efficacy measurement was reduction in agitation, as measured by the Positive and Negative Syndrome Scale-Excited Component (PANSS-EC) score. Adverse events and scores on EPS rating scales were assessed. Results: A total of 311 patients (204 men, 107 women; mean [SD] age, 38.2 [11.6] years) were enrolled (131, 126, and 54 patients in the olanzapine, haloperidol, and placebo groups, respectively). In all, 93.1% (122/131) of olanzapine-treated patients and 92.1% (116/126) of haloperidol-treated patients completed the IM period and entered the PO period; 85.5% (112/131) of olanzapine-treated patients and 84.1% (106/126) of haloperidol-treated patients completed the PO period. IM olanzapine and IM haloperidol effectively reduced agitation over 24 hours (mean [SD] PANSS-EC change, -7.1 [4.8] vs -6.7 [4.3], respectively). Reductions in agitation were sustained throughout the PO period with both study drugs (mean [SD] change from PO period baseline, -0.6 [4.8] vs -1.3 [4.4], respectively). During PO treatment, haloperidol-treated patients spontaneously reported significantly more acute dystonia than olanzapine-treated patients (4.3% [5/116] vs 0% [0/122], respectively; P = 0.026) and akathisia (5.2% [6/116] vs 0% [0/122], respectively; P = 0.013). Significantly more haloperidol-treated patients than olanzapine-treated patients met categorical criteria for treatment-emergent akathisia (18.5% [17/92] vs 6.5% [7/107], respectively; P = 0.015). Conclusions: In the acutely agitated patients with schizophrenia in this study, both IM olanzapine 10 mg and IM haloperidol 7.5 mg effectively reduced agitation over 24 hours. This alleviation of agitation was sustained following transition from IM therapy to 4 days of PO treatment (5-20 mg/d for both). During the 4 days of PO treatment, olanzapine-treated patients did not spontaneously report any incidences of acute dystonia, and olanzapine had a superior EPS safety profile to that of haloperidol. The combination of IM and PO olanzapine may help improve the treatment of acutely agitated patients with schizophrenia. Copyright (C) 2003 Excerpta Medica, Inc.

Intramuscular Olanzapine and Intramuscular Haloperidol in Acute Schizophrenia: Antipsychotic Efficacy and Extrapyramidal Safety During the First 24 Hours of Treatment

To determine the antipsychotic efficacy and extrapyramidal safety of intramuscular (IM) olanzapine and IM haloperidol during the first 24 hours of treatment of acute schizophrenia. Method: Patients (n = 311) with acute schizophrenia were randomly allocated (2:2: 1) to receive IM olanzapine (10.0 mg, n = 131), IM haloperidol (7.5 mg, n = 126), or IM placebo (n = 54). Results: After the first injection, IM olanzapine was comparable to IM haloperidol and superior to IM placebo for reducing mean change scores from baseline on the Brief Psychiatric Rating Scale (BRPS) Positive at 2 hours (-2.9 olanzapine, -2.7 haloperidol, and -1.5 placebo) and 24 hours (-2.8 olanzapine, -3.2 haloperidol, and -1.3 placebo); the BPRS Total at 2 hours (-14.2 olanzapine,-13.1 haloperidol, and -7.1 placebo) and 24 hours (-12.8 olanzapine, -12.9 haloperidol, and -6.2 placebo); and the Clinical Global Impressions (CGI) scale at 24 hours (-0.5 olanzapine, -0.5 haloperidol, and -0.1 placebo). Patients treated with IM olanzapine had significantly fewer incidences of treatment-emergent parkinsonism (4.3% olanzapine vs 13.3% haloperidol, P = 0.036), but not akathisia (1.1% olanzapine vs 6.5% haloperidol, P = 0.065), than did patients treated with IM haloperidol; they also required significantly less anticholinergic treatment (4.6% olanzapine vs 20.6% haloperidol, P < 0.001). Mean extrapyramidal symptoms (EPS) safety scores improved significantly from baseline during IM olanzapine treatment, compared with a general worsening during IM haloperidol treatment (Simpson-Angus Scale total score mean change: -0.61 olanzapine vs 0.70 haloperidol; P < 0.001; Barnes Akathisia Scale global score mean change: -0.27 olanzapine vs 0.01 haloperidol; P < 0.05). Conclusion: IM olanzapine was comparable to IM haloperidol for reducing the symptoms of acute schizophrenia during the first 24 hours of treatment, the efficacy of both being evident within 2 hours after the first injection. In general, more EPS were observed during treatment with IM haloperidol than with IM olanzapine.

Cell death and degeneration in the symbiotic dinoflagellates of the coral Stylophora pistillata during bleaching

Rising sea temperatures are increasing the incidences of mass coral bleaching (the dissociation of the coral-algal symbiosis) and coral mortality. In this study, the effects of bleaching (induced by elevated light and temperature) on the condition of symbiotic dinoflagellates (Symbiodinium sp.) within the tissue of the hard coral Stylophora pistillata (Esper) were assessed using a suite of techniques. Bleaching of S. pistillata was accompanied by declines in the maximum potential quantum yield of photosynthesis (F-v/F-m, measured using pulse amplitude modulated [PAM] fluorometry), an increase in the number of Sytox-green-stained algae (indicating compromised algal membrane integrity and cell death), an increase in 2',7'-dichlorodihydrofluroscein diacetate (H(2)DCFDA)stained algae (indicating increased oxidative stress), as well as ultrastructural changes (vacuolisation, losses of chlorophyll, and an increase in accumulation bodies). Algae expelled from S. pistillata exhibited a complete disorganisation of cellular contents; expelled cells contained only amorphous material. In situ samples taken during a natural mass coral bleaching event on the Great Barrier Reef in February 2002 also revealed a high number of Sytox-labelled algae cells in symbio. Dinoflagellate degeneration during bleaching seems to be similar to the changes resulting from senescence-phase cell death in cultured algae. These data support a role for oxidative stress in the mechanism of coral bleaching and highlight the importance of algal degeneration during the bleaching of a reef coral.

Randomized, controlled trial of topical exit-site application of honey (Medihoney) versus Mupirocin for the prevention of catheter-associated infections in hemodialysis patients

The clinical usefulness of hemodialysis catheters is limited by increased infectious morbidity and mortality. Topical antiseptic agents, such as mupirocin, are effective at reducing this risk but have been reported to select for antibiotic-resistant strains. The aim of the present study was to determine the efficacy and the safety of exit-site application of a standardized antibacterial honey versus mupirocin in preventing catheter-associated infections. A randomized, controlled trial was performed comparing the effect of thrice-weekly exit-site application of Medihoney versus mupirocin on infection rates in patients who were receiving hemodialysis via tunneled, cuffed central venous catheters. A total of 101 patients were enrolled. The incidences of catheter-associated bacteremias in honey-treated (n = 51) and mupirocin-treated (n = 50) patients were comparable (0.97 versus 0.85 episodes per 1000 catheter-days, respectively; NS). On Cox proportional hazards model analysis, the use of honey was not significantly associated with bacteremia-free survival (unadjusted hazard ratio, 0.94; 95% confidence interval, 0.27 to 3.24; P = 0.92). No exit-site infections occurred. During the study period, 2% of staphylococcal isolates within the hospital were mupirocin resistant. Thrice-weekly application of standardized antibacterial honey to hemodialysis catheter exit sites was safe, cheap, and effective and resulted in a comparable rate of catheter-associated infection to that obtained with mupirocin (although the study was not adequately powered to assess therapeutic equivalence). The effectiveness of honey against antibiotic-resistant microorganisms and its low likelihood of selecting for further resistant strains suggest that this agent may represent a satisfactory alternative means of chemoprophylaxis in patients with central venous catheters.

Clinical tests of musculoskeletal dysfunction in the diagnosis of cervicogenic headache

Persistent intermittent headache is a common disorder and is often accompanied by neck aching or stiffness, which could infer a cervical contribution to headache. However, the incidence of cervicogenic headache is estimated to be 14-18% of all chronic headaches, highlighting the need for clear criterion of cervical musculoskeletal impairment to identify cervicogenic headache sufferers who may benefit from treatments such as manual therapy. This study examined the presence of cervical musculoskeletal impairment in 77 subjects, 27 with cervicogenic headache, 25 with migraine with aura and 25 control subjects. Assessments included a photographic measure of posture, range of movement, cervical manual examination, pressure pain thresholds, muscle length, performance in the cranio-cervical flexion test and cervical kinaesthetic sense. The results indicated that when compared to the migraine with aura and control groups who scored similarly in the tests, the cervicogenic headache group had less range of cervical flexion/extension (P = 0.048) and significantly higher incidences of painful upper cervical joint dysfunction assessed by manual examination (all P < 0.05) and muscle tightness (P < 0.05). Sternocleidomastoid normalized EMG values were higher in the latter three stages of the cranio-cervical flexion test although they failed to reach significance. There were no between group differences for other measures. A discriminant analysis revealed that manual examination could discriminate the cervicogenic headache group from the other subjects (migraine with aura and control subjects combined) with an 80% sensitivity.

The importance of host ecology in thelastomatoid (Nematoda : Oxyurida) host specificity

An experimental investigation of host specificity within the Thelastomatoidea is presented by means of a comparison of the thelastomatoids of two panesthiine cockroaches, Panesthia cribrata and R tryoni tryoni, with those of other log-dwelling arthropods and those of leaf litter dwelling arthropods found near by. 145 log-dwelling and leaf-litter dwelling arthropods, representing adjacent ecological niches, were collected from Lamington National Park, Queensland, Australia. A high degree of thelastomatoid species sharing (19 incidences from 26 specimens) occurs between log-dwelling arthropods and the two cockroach species. No overlap in thelastomatoid fauna was observed between the log dwelling and leaf-litter dwelling groups. Our results suggest that host specificity of thelastomatoids is largely dictated by host ecology. (c) 2006 Elsevier Ireland Ltd. All rights reserved.

Graduate overeducation and its effects among recently arrived immigrants to Australia: A longitudinal survey

There is increasing importance attached to skill-based immigration in many countries including Australia. This paper investigates the incidences, determinants, and returns to graduate overeducation among tertiary qualified immigrants during the early phase of their settlement in Australia. We place particular emphasis on visa categories and region of origin. As expected, those on visas with higher skill requirements perform better in the labour market. The bulk of these are immigrants from English Speaking Backgrounds (ESB). Non-English Speaking Background (NESB) immigrants, on the other hand, have higher and persistent rates of overeducation. The wage returns to required and surplus education match the stylized facts of overeducation for ESB and Other NESB immigrants while Asian NESB immigrants receive no return to surplus education. Thus, the results suggest that NESB graduate immigrants are a heterogeneous group, with Asian graduate immigrants facing greater assimilation hurdles in the Australian labour market.

GESTÃO DA COMUNICAÇÃO INTEGRADA: CONTRIBUIÇÕES PARA UMA ABORDAGEM SISTÊMICA Um estudo de caso da rede Magazine Luiza

O estudo investiga os fluxos de comunicação nas organizações, refletindo sobre o modelo dos 3 Puts (inputs, throughputs, outputs), que propicia uma visão sistêmica interdepartamental, aumentando a interação e a consciência entre os setores para a realização dos objetivos organizacionais. Apresenta as características e intersecções entre comunicação mercadológica, comunicação institucional e comunicação administrativa. Oferece um ponto de encontro entre esses conceitos e reflete sobre o modelo de Comunicação Integrada Tridimensional, quando todas as ações da comunicação organizacional convergem, baseadas no trinômio Missão, Visão e Valores e nos 14 passos da comunicação de Yanaze (2013). Outra análise é verificar os pressupostos teóricos com um estudo de caso da empresa Magazine Luiza, a fim de verificar de que forma o conceito de comunicação integrada está fundamentado no planejamento e na unicidade da mensagem desta organização. A metodologia consistiu em pesquisa bibliográfica, estudo de caso e aplicação de entrevistas. Entre os resultados encontrados, demonstrou-se, tanto na pesquisa teórica quanto empírica, que a abordagem sistêmica e a proposta de Comunicação 3D, de fato, oferecem caminhos para uma eficaz gestão da comunicação integrada.

REDES DE APOIO SOCIAL E QUALIDADE DE VIDA EM HOMENS IDOSOS DE SÃO CAETANO DO SUL

O presente estudo tem como objetivo, identificar as características sócio-demográficas de um grupo de homens idosos moradores de São Caetano do Sul, as principais redes de apoio social entre esses idosos e investigar o nível de qualidade de vida dos mesmos. Os dados foram colhidos entre outubro de 2005 e março de 2006. Ao todo foram entrevistados 40 idosos, todos do gênero masculino, com idade média de 70,68 anos. Desses sujeitos, 20 foram entrevistados em Centro de Convivência (CC) para a terceira idade e 20 foram entrevistados nas ruas e nas praças de São Caetano do Sul. Foram utilizados dois questionários sendo um sobre rede de apoio social e o outro sobre qualidade de vida, o WHOQOL bref. Ao final dos questionários foram incluídas duas questões para investigar as providências tomadas em relação à velhice e como eles gastam seu dinheiro. A comparação entre os dois subgrupos permitiu constatar que os idosos do CC revelaram maior participação em atividades de grupo (p < 0,05) e maior freqüência na prática esportiva semanal (p < 0,01). Em questões sobre situações em que as pessoas procuram por outras, em busca de companhia, apoio ou ajuda, os idosos que não freqüentam o CC obtiveram melhores resultados (p< 0,05), bem como são eles que podem contar com alguém para compartilhar suas preocupações e medos mais íntimos (p < 0,05). Idosos divorciados tendem a contar com alguém que os ajude se ficarem de cama (p < 0,05) mais do que os idosos viúvos e também obtiveram mais ajuda para preparar seus alimentos, caso adoeçam do que os idosos viúvos (p< 0,01). Foi possível observar que há maior incidência de idosos viúvos e separados que freqüentam o CC bem como se verificou que a rede social dos mesmos apresentou-se mais deficiente. Entretanto foi observada melhor qualidade de vida relatada entre esses idosos em relação aos abordados na rua (p < 0,05). Concluímos que a participação no CC para a terceira idade, pode cooperar para melhora da qualidade de vida, devido às atividades esportivas, os eventos sociais e a infra-estrutura que o mesmo proporciona à terceira idade

An investigation into the synaptic conditions and celluar mechanisms underlying cerebellar synaptic plasticity

The direction of synaptic plasticity at the connection between parallel fibres (PFs) and Purkinje cells can be modified by PF stimulation alone. Strong activation (Hartell, 1996) or high frequency stimulation (Schreurs and Alkon, 1993) of PFs induced a long-term depression (LTD) of PF-mediated excitatory postsynaptic currents. Brief raised frequency molecular layer stimulation produced a cAMP-dependent long-temi potentiation (LTP) of field potential (FP) responses (Salin et al., 1998). Thin slices of cerebellar vermis were prepared from 14-21 day old male Wistar rats decapitated under Halothane anaesthesia. FP's were recorded from the Purkinje cell layer in response to alternate 0.2Hz activation of stimulating electrodes placed in the molecular layer. In the presence of picrotoxin, FPs displayed two tetrodotoxin-sensitive, negative-going components termed N1 and N2. EPs were graded responses with paired pulse facilitation and were selectively blocked by 101AM 6-cyano-7-nitroquinoxaline-2,3-dicne (CNQX) an antagonist at iy,-amino-3-hydroxy-5-methyl-4-isoxazolepropionate-type ionotropic glutamate receptors (AMPAR) suggesting that they were primarily PE-mediated. The effects of raised stimulus intensity (RS) and/or increased frequency (IF) activation of the molecular layer on FP responses were examined. In sagittai and transverse slices combined RS and IF molecular layer activation induced a LTD of the N2 component of FP responses. RSIF stimulation produced fewer incidences of LTD in sagittal slices when an inhibitor of nitric oxide synthase (NOS), guanylate cyclase (GC), protein kinase G (PKG) or the GABAB receptor antagonist CGP62349 was included into the perfusion medium. Application of a nitric oxide (NO) donor, a cyclic guanosine monophosphate (cGMP) analogue or a phosphodiesterase (PDE) type V inhibitor to prevent cGMP breakdown paired with IF stimulation produced an acute depression, Raised frequency (RF) molecular layer stimulation produced a slowly emerging LTD of N2 in sagittal slices that was largely blocked in the presence of NOS, cGMP or PKG inhibitors. In transverse slices RE stimulation produced a LTP of the N2 component that was prevented by an inhibitor of protein kinase A or NOS. Inhibition of cGMP-signalling frequently revealed an underlying potentiation suggesting that cGMP activity might mask the effects of cAMP. In sagittal slices RE stimulation resulted in a potentiation of FPs when the cAMP-specific PDE type IV inhibitor rolipram was incorporated into the perfusion medium. In summary, raised levels of PE stimulation can alter the synaptic efficacy at PF-Purkinje cell synapses. The results provide support for a role of NO/cGMP/PKG signalling in the induction of LTD in the cerebellar cortex and suggest that activation of GABAa receptors might also be important. The level of cyclic nucleotide-specific PDE activities may be crucial in determining the level of cGMP and CAMP activity and hence the direction of synaptic plasticity.
