The relationship between the perception of distributed leadership in secondary schools and teachers' and teacher leaders' job satisfaction and organizational commitment
This study investigates the relation between distributed leadership, the cohesion of the leadership team, participative decision-making, context variables, and the organizational commitment and job satisfaction of teachers and teacher leaders. A questionnaire was administered to teachers and teacher leaders (n=1770) from 46 large secondary schools. Multiple regression analyses and path analyses revealed that the study variables explained significant variance in organizational commitment. The degree of explained variance for job satisfaction was considerably lower compared to organizational commitment. Most striking was that the cohesion of the leadership team and the amount of leadership support was strongly related to organizational commitment, and indirectly to job satisfaction. Decentralization of leadership functions was weakly related to organizational commitment and job satisfaction
Intestinal Perforations in Behçet’s Disease
Behçet’s disease accompanied by intestinal involvement is called intestinal Behçet’s disease. The intestinal ulcers of Behçet’s disease are usually multiple and scattered and tend to perforate easily, so that many patients require emergency operation. The aim of this study is to determine the extent of surgical resection necessary to prevent reperforation and to point out the findings of concurrent oral and genital ulcers and multiple intestinal perforations in all patients of our series. During a 25-year study period, information of 125 Behçet’s disease cases was gathered. Among the 82 patients who were diagnosed with intestinal Behçet’s disease, 22 cases had intestinal perforations needing emergency laparotomy. We investigated and analyzed these cases according to the patients’ demographic characteristics, clinical presentations, laboratory data, and surgical outcome. There were 14 men and 8 women ranging from 22 to 65 years of age. Nine cases were diagnosed preoperatively, and the diagnoses were confirmed in all 22 cases during the surgical intervention. Surgical resection was performed in every patient, with right hemicolectomy and ileocecal resection in 11 cases, partial ileum resection in 8 cases with two reperforations, and ileocecal resection in 3 cases with one reperforation
Dislexia e ensino-aprendizagem de lĂngua portuguesa : um estudo de caso
Monografia (graduação)—Universidade de BrasĂlia, Instituto de Letras, 2013.Esta pesquisa trata da dislexia e do ensino-aprendizagem de LĂngua Portuguesa para dislĂ©xicos, com base em um estudo de caso com estudante dislĂ©xico da rede pĂşblica de ensino do Plano Piloto. Dentre as questões abordadas, estĂŁo as definições da dislexia, seus tipos e possĂveis tratamentos, alĂ©m da discussĂŁo do espaço que tal distĂşrbio de aprendizagem tem na educação, a sugestĂŁo de inclusĂŁo da dislexia na Educação Especial e, consequentemente, nas salas de recursos e a adequação da metodologia de ensino, baseada na exploração dos gĂŞneros textuais e dos multiletramentos, dentro da perspectiva Sociointeracionista de Vygotsky e da proposta de professor libertador, de Paulo Freire

Comparative analysis of the association of HLA-B*51 suballeles with Behcet's disease in patients of German and Turkish origin
The distribution of the different HLA-B*51 suballeles among patients with Behcet's disease (BD) of German (n = 33) and Turkish (n = 92) origin in comparison to their presence in the respective ethnically matched healthy control groups (German: n=325, Turkish: n=93) was studied. HLA-B*51x was significantly increased in both patient groups in comparison to the controls (Germans: 58% vs. 12%, OR 9.76, P <0.001; Turkish: 75% vs. 25%, OR 9.13, P <0.001), Molecular subtyping of B*51x revealed HLA-B*51011 and B*5108 as the predominant suballeles in both patient groups and controls although with a slightly increased frequency of HLA-B*5108 in the diseased individuals. HLA-B*5105 was the only further HLA-B*51x subtype detected in one Turkish patient heterozygous also for HLA-B*5101. HLA-B*5107 although present in a Turkish as well as German control was absent in the patient groups. There was also a tendency towards a higher degree of homozygosity for HLA-B*51x in both patient groups versus the matched controls (Germans: 10% in patients vs. 2,5%. in controls; Turkish: 27% in patients vs. 13" in controls), Our study further supports previous hypothesis of an association of BD with B51 suballeles which share aminoacid residues at positions 63 and 67 as well as at positions 77-83 for specific peptide binding and natural killer (NK)-cell interactions. This applies to HLA-B*5101 and B*5108, but not to HLA-B*5107 different at position 67, which could be negatively associated with BD
