Discutindo a educação ambiental no cotidiano escolar: desenvolvimento de projetos na escola formação inicial e continuada de professores

A presente pesquisa buscou discutir como a Educação Ambiental (EA) vem sendo trabalhada, no Ensino Fundamental e como os docentes desta escola compreendem e vem inserindo a EA no cotidiano escolar., em uma escola estadual do município de Tangará da Serra/MT, Brasil. Para tanto, realizou-se entrevistas com os professores que fazem parte de um projeto interdisciplinar de EA na escola pesquisada. Verificou-se que o projeto da escola não vem conseguindo alcançar os objetivos propostos por: desconhecimento do mesmo, pelos professores; formação deficiente dos professores, não entendimento da EA como processo de ensino-aprendizagem, falta de recursos didáticos, planejamento inadequado das atividades. A partir dessa constatação, procurou-se debater a impossibilidade de tratar do tema fora do trabalho interdisciplinar, bem como, e principalmente, a importância de um estudo mais aprofundado de EA, vinculando teoria e prática, tanto na formação docente, como em projetos escolares, a fim de fugir do tradicional vínculo “EA e ecologia, lixo e horta”.Facultad de Humanidades y Ciencias de la Educació

Creating one's reality: The interaction of politics perceptions and enactment behavior

The current study investigated the previously unexamined relationship between politics perceptions and employee enactment behavior. Consistent with previous job stress and sense-making research, we hypothesized that individuals reporting low levels of enactment behaviors would be more adversely affected by politics perceptions than those who engaged in high levels of enactment behavior. Results across two samples provided strong support for the hypothesized relationships. Specifically, employees who reported low levels of enactment behavior experienced less satisfaction, less person–environment fit, and reported lower levels of effort when faced with highly political environments. Conversely, levels of satisfaction and person–environment fit perceptions of individuals reporting high levels of enactment behaviors were largely unaffected by highly political contexts. Implications of these findings, strengths and limitations, and avenues for future research are provided

Self-regulation failure as a moderator of the pops–work outcomes relationships

Purpose Drawing upon cognitive control theory, we examine the effects of self-regulation failure (SRF) on the relationships between perceptions of organizational politics (POPs) and tension, exhaustion, satisfaction, work effort, perceived resource availability and performance/contribution. Design/methodology/approach We test hypotheses across three unique studies (Study 1: 310 employees from various occupations; Study 2: 124 administrative/support employees; Study 3: 271 Chinese hotel managers) using hierarchical moderated regression analyses. Findings Across studies, results suggest that POPs had a minimal impact on work attitudes, behaviors and health-related outcomes when SRF was low. However, employees experiencing high SRF reported adverse consequences in high POPS settings. Research limitations/implications These studies relied on self-report data. However, we implemented design features to mitigate potential concerns and analytic techniques to determine method effects. This paper contributed to the POPs literature by explaining how SRF and POPs interact to impact meaningful work outcomes. Practical implications Leaders should receive training to help them identify and address indicators of SRF. Leaders can also implement intervention programs to help calm employees who experience SRF. Social implications Leaders should receive training to help them identify and address indicators of SRF. Leaders can also implement programs to help assist employees who demonstrate adverse effects from SRF. Originality/value This paper integrates the research on SRF and politics to examine the collective impact these variables have on workers. Our three-study package also addresses the call for more studies to examine how politics operate across cultures

IL-17 signaling in steatotic hepatocytes and macrophages promotes hepatocellular carcinoma in alcohol-related liver disease.

Background & aimsChronic alcohol consumption is a leading risk factor for the development of hepatocellular carcinoma (HCC), which is associated with a marked increase in hepatic expression of pro-inflammatory IL-17A and its receptor IL-17RA.MethodsGenetic deletion and pharmacological blocking were used to characterize the role of IL-17A/IL-17RA signaling in the pathogenesis of HCC in mouse models and human specimens.ResultsWe demonstrate that the global deletion of the Il-17ra gene suppressed HCC in alcohol-fed diethylnitrosamine-challenged Il-17ra-/- and major urinary protein-urokinase-type plasminogen activator/Il-17ra-/- mice compared with wild-type mice. When the cell-specific role of IL-17RA signaling was examined, the development of HCC was decreased in both alcohol-fed Il-17raΔMΦ and Il-17raΔHep mice devoid of IL-17RA in myeloid cells and hepatocytes, but not in Il-17raΔHSC mice (deficient in IL-17RA in hepatic stellate cells). Deletion of Il-17ra in myeloid cells ameliorated tumorigenesis via suppression of pro-tumorigenic/inflammatory and pro-fibrogenic responses in alcohol-fed Il-17raΔMΦ mice. Remarkably, despite a normal inflammatory response, alcohol-fed Il-17raΔHep mice developed the fewest tumors (compared with Il-17raΔMΦ mice), with reduced steatosis and fibrosis. Steatotic IL-17RA-deficient hepatocytes downregulated the expression of Cxcl1 and other chemokines, exhibited a striking defect in tumor necrosis factor (TNF)/TNF receptor 1-dependent caspase-2-SREBP1/2-DHCR7-mediated cholesterol synthesis, and upregulated the production of antioxidant vitamin D3. The pharmacological blocking of IL-17A/Th-17 cells using anti-IL-12/IL-23 antibodies suppressed the progression of HCC (by 70%) in alcohol-fed mice, indicating that targeting IL-17 signaling might provide novel strategies for the treatment of alcohol-induced HCC.ConclusionsOverall, IL-17A is a tumor-promoting cytokine, which critically regulates alcohol-induced hepatic steatosis, inflammation, fibrosis, and HCC.Lay summaryIL-17A is a tumor-promoting cytokine, which critically regulates inflammatory responses in macrophages (Kupffer cells and bone-marrow-derived monocytes) and cholesterol synthesis in steatotic hepatocytes in an experimental model of alcohol-induced HCC. Therefore, IL-17A may be a potential therapeutic target for patients with alcohol-induced HCC
