A Meta-Analysis of Organizational Factors Effective of Efficiency and Motivation of Teachers
The data of the present research was initially collected by using research findings systematic review for the study of the organizational factors effective on teachers’ efficiency and motivation. Then the meta-analysis method was used to respond to questions. The statistical population of this research includes all researches which were conducted inside Iran in the field of factors effective on teachers’ efficiency and motivation between 1996 to 2016. On this basis, the statistical population was identified and relevant data was coded by internet research in internal data banks and also manual search in Tehran universities. Finally, 18 studies were included in the present meta-analysis. To collect the required data meta-analysis, worksheet form was used. Data analysis results show that the size index of studies compound effect was 0.10 under the fixed model and 0.17 under the random model. In the separation study of the size of variables effect, the organization health factors, organizational climate, students’ motivation, director’s attention, and relationship-oriented management style, had the highest effect on the teachers’ efficiency and motivation, respectively. In egger’s regression method, the regression constant was estimated equal to 0.01 which its level of significance is less than 0.05; therefore according to the egger’s regression, publication bias exists. Also, moderating analysis was done for variables of publication year and place of carrying out the research which shows the ineffectiveness of moderating variables of the year of conduction of the research and the place of conduction of the research on the studies’ results
The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019
Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

نقش پیشبینیکنندگی محبوبیت والدین و نشاط معنوی از احساس خودارزشمندی در نوجوانان دارای والد با آسیب بینایی در خانوادههای تحت پوشش سازمان بهزیستی
سابقه و هدف: نشاط معنوی مقولهای است که با وجود اهمیت فراوان آن بهعنوان موضوعی مجزا کمتر به آن توجه شده است. نشاط لازمۀ زندگی و عامل محرکی برای نیل انسان به سلامت روانی و قُرب الیالله است. در عین حال، عامل خانواده بهویژه محبوبیت والدین با بهزیستی روانی و کاهش آسیبهای اجتماعی-روانی ارتباط معناداری دارد. ازاینرو، این پژوهش با هدف بررسی نقش پیشبینیکنندگی محبوبیت والدین و نشاط معنوی با احساس خودارزشمندی نوجوانان انجام شد.
روش کار: پژوهش حاضر توصیفی از نوع همبستگی است. جامعۀ آماری همۀ نوجوانان دارای والد نابینای تحت پوشش سازمان بهزیستی در 31 استان ایران در سال 1400 بود که 240 نفر از آنان بهروش نمونهگیری هدفمند و برحسب مراجعات متوالی به مراکز بهزیستی انتخاب شدند و پرسشنامههای احساس خودارزشمندی روزنبرگ، نشاط معنوی افروز و محبوبیت والدین افروز و اسدی را تکمیل کردند. برای تحلیل دادهها از ضریب همبستگی پیرسون و رگرسیون چندگانۀ سلسلهمراتبی استفاده شد. در این پژوهش همۀ موارد اخلاقی رعایت شده است و مؤلفان مقاله تضاد منافعی گزارش نکردهاند.
یافتهها: نتایج پژوهش نشان داد بین نشاط معنوی با احساس خودارزشمندی (63/0=r و 011/0>P) و همچنین بین محبوبیت والدین (52/0=r و 017/0>P) با احساس خودارزشمندی همبستگی مثبت و معنادار برقرار بود. تحلیل رگرسیون نشان داد بهترتیب نشاط معنوی توان تبیین 20% از واریانس احساس خودارزشمندی، نشاط معنوی و محبوبیت والدین با هم توان تبیین 28% از واریانس احساس خودارزشمندی؛ و محبوبیت والدین مستقل از نشاط معنوی توان تبیین 7% از این واریانس را داشتند. دو عامل محبوبیت مادر و پدر نیز توانستند 8% از واریانس احساس خودارزشمندی را پیشبینی کنند. در میان متغیّرهای مربوط به محبوبیت مادر و پدر، محبوبیت مادر با ضریب بتای 26/0=β قویترین پیشبینیکننده بود.
نتیجهگیری: ازآنجاییکه محبوبیت والدین و نشاط معنوی میزان بالایی از تغییرپذیری احساس خودارزشمندی را تبیین میکنند، میتوان توجه به این عوامل را در بهبود احساس خودارزشمندی نوجوانان مهم دانست و در برنامههای ارتقای سلامت در جامعه مدنظر قرار داد
