Teachers’ views on causes leading to their burnout

Teaching is a challenging profession sometimes leading to teachers’ burnout: a syndrome of emotional exhaustion, depersonalisation, and reduced personal accomplishment. Burnout effects range from psychological, physical, and behavioural symptoms to increased turnover, which affects students and schools. This study identifies levels of and factors causing Lebanese teachers’ burnout by eliciting their perspectives about the matter. A multiple-case studies design is used; instruments include interviews, researcher’s reflective journal, and questionnaires adapted from the Maslach Burnout Inventory–Educators Survey. Nine teachers who left the profession during the first five years of teaching were interviewed and 92 teachers in service responded to the questionnaire. A cross-case synthesis helped to compare the data between cases in order to discover whether similarities can be found. Triangulation of data is performed through comparing results from each instrument and identifying common categories that are used to address the research questions. Findings show that workload, school environment, coordination/mentoring, classroom environment, and emotional factors are major causes of burnout. This study provided insight on how to identify causes and symptoms of teacher burnout to help prevent the occurrence of the syndrome.     

Learning From Our Mistakes: Improvements in Spelling Lead to Gains in Reading Speed

The present study tested the hypothesis that underlying orthographic representations vary in completeness within the individual, which is manifested in both spelling accuracy and reading speed. Undergraduate students were trained to improve their spelling of difficult words. Word reading speed was then measured for these same words, allowing for a direct evaluation of whether improvements in spelling would bring about faster reading speeds. Results were clear: Spelling accuracy and reading speed were strongly related across and within participants. Most important, words that improved in spelling accuracy were read more rapidly at posttest than words that did not show improvement in spelling. These results provide direct evidence showing that the quality of orthographic representations, as indexed by spelling accuracy, directly relates to reading speed. This is consistent with the lexical quality hypothesis and highlights the relevance of spelling in literacy acquisition.     

Loss of proteinase binding capacity of plasma alpha2 macroglobulin in some disease conditions

Alpha₂-macroglobulin (MG) levels in terms of proteinase binding capacity in fresh plasma of diabetics (males 183.9±60.3 mg MG/dl, females 173.8±49.7) and viral hepatitis patients (195.2±41.4) were comparable to normal sujbects (males 180.0±28.6, females 213.0±59.6) whereas in renal failure the values were decreased (144.0±30.0) and was found to be increased in nephrotic syndrome (331.5±47.9). MG activity was stable in normals and nephrotic patients in plasma on standing for 12 hr. at 37°C. In other conditions, the proteinase binding capacity was considerably reduced (mean decrease: 51.2% in diabetes, 64.0% in renal failure and 52.6% in viral hepatitis). Concentration of MG determined by immunoelectrophoresis did not however change in diabetic plasma on 12 hr. incubation. It is proposed that proteinases are continously generated in plasma in some disease conditions which bind to MG causing reduction in measured proteinase binding capacity.     

Religiosity as a moderator of the links between parental psychological control and children's prosociality

Three studies examined the links between psychological control and prosociality in middle childhood, and the role of religiosity as a moderator. Study 1 (101 Israeli Jewish families, ages 6–9, 50% girls) found a significant interaction, with a negative association between maternal psychological control and children's prosociality in secular but not in religious families. Study 2 (161 Israeli Jewish families, ages 6–12, 48% girls) replicated this interaction for mothers using a continuous religiosity measure. Study 3 (64 Arab Muslim Israeli families, ages 6–8.5, 50% girls) also found a significant interaction, with a positive link between psychological control and prosociality seen at higher, but not at lower, religiosity levels. The findings suggest that religiosity may alter the meaning and consequences of parenting practices.     

Serum alpha-2-macroglobulin, antitrypsin and antichymotrypsin activities in patients receiving treatment with cyclosporine

Cyclosporine has been reported to function as an inhibitor of the chymotrypsin like activity of proteasome. We hypothesized that the administration of an exogenous proteinase inhibitor may affect the activities of the naturally occurring serum anti proteinases. The aim of this study was to observe the pattern of alteration of serum alpha 2 macroglobulin (AMG), alpha 1- antitrypsin (AT) and alpha 1-antichymotrypsin (ACT) activities in renal transplant patients receiving the immunosuppressive drug, cyclosporine. Patients (97) who had received a single renal allograft were inducted into the study. Subjects were on a twice-daily dosage of cyclosporine capsules. Trough (Co) and two-hour post dose (C 2) cyclosporine levels were regularly estimated and all patients had stable creatinine levels. In 5 newly transplanted patients, antiproteinase activities were estimated weekly over a 4-week period as their cyclosporine doses were gradually tapered. Average serum activities of ACT and AMG in the transplant group were significantly less than in the control group (p<0.002 and p<0.003 respectively). AT and ACT activities fell gradually over 4 weeks. AMG activities showed a biphasic pattern, initially falling by almost 50% in the second week, increasing marginally in the third week and decreasing to less than 50% of the activities observed in the first week. Serum antiproteinase activities of serum alpha 2 macroglobulin (AMG), alpha 1-antitrypsin (AT) and alpha 1-antichymotrypsin (ACT) were found to be altered in renal transplant patients receiving cyclosporine.     

Immunomodulation of excretory secretory materials from the filarial parasite<Emphasis Type="Italic">Setaria digitata</Emphasis>

ES materials released along with the release of mf showed immunosuppression as evidenced by a decrease in T lymphocyte levels in the immunised animals. Lipid fractions of the mf associated ES materials and protein fractions of the detergent soluble materials were found to cause suppression of immune response in the host. Further study revealed that the suppression associated with the lipid fractions is actually the end result and that mf associated ES materials is actually a mixture of immunosuppressive and immunopotentiating components and the release of the components is most likely regulated.     

Cognitive Stimulation as a Mechanism Linking Socioeconomic Status With Executive Function: A Longitudinal Investigation

Executive functions (EF), including working memory, inhibition, and cognitive flexibility, vary as a function of socioeconomic status (SES), with children from economically disadvantaged backgrounds having poorer performance than their higher SES peers. Using observational methods, we investigated cognitive stimulation in the home as a mechanism linking SES with EF. In a sample of 101 children aged 60–75 months, cognitive stimulation fully mediated SES-related differences in EF. Critically, cognitive stimulation was positively associated with the development of inhibition and cognitive flexibility across an 18-month follow-up period. Furthermore, EF at T1 explained SES-related differences in academic achievement at T2. Early cognitive stimulation—a modifiable factor—may be a desirable target for interventions designed to ameliorate SES-related differences in cognitive development and academic achievement.     

The Kaufman Assessment Battery for Children (K-ABC) in the assessment of learning disabled children

The authors of the Kaufman Assessment Battery for Children (K-ABC) assert that, in addition to a discrepancy between learning potential and academic achievement, learning disability is characterized by poor sequential relative to simultaneous processing skills. The present study was designed to determine whether the K-ABC could discriminate between learning disabled and normal children on the basis of these characteristics. Forty-three LD pupils from 7 to 12 years of age and 20 normally achieving children of similar age were administered the K-ABC. Results indicated that, for both the LD and the normal children, scores on the Sequential Processing Scale were significantly lower than on the Simultaneous Processing Scale. In addition, the aiscrepancy between Simultaneous and Sequential scale scores was similarly distributed in both groups. The LD group scored lower and the normal group higher on the Achievement Scale than on the Mental Processing Composite. The results, therefore, indicated that the K-ABC differentiated LD from normal children in terms of Achievement relative to M.P.C. scores; however, it failed to reveal a unique profile pattern related to simultaneous vs. sequential processing skills for the LD group. Further analyses of the relationship between K-ABC processing scale scores and WISC-R scores, as recategorized by Bannatyne, revealed significant correlations between measures, indicating similar underlying theoretical constructs.
