1 An Updated Systematic Review and Meta-regression Analysis: Mental Disorders Among Adolescents in Juvenile Detention and Correctional Facilities
یک مرور سیستماتیک و تجزیه و تحلیل متا رگرسیون به روز شده: اختلالات روانی در نوجوانان در بازداشتگاههای نوجوانان و زندانهای اصلاح و تربیت-2020
Objective: To synthesize evidence on the prevalence of mental disorders in adolescents in juvenile detention and correctional facilities and examine sources of heterogeneity between studies. Method: Electronic databases and relevant reference lists were searched to identify surveys published from January 1966 to October 2019 that reported on the prevalence of mental disorders in unselected populations of detained adolescents. Data on the prevalence of a range of mental disorders (psychotic illnesses, major depression, attention-deficit/hyperactivity disorder [ADHD], conduct disorder, and posttraumatic stress disorder [PTSD]) along with predetermined study characteristics were extracted from the eligible studies. Analyses were reported separately for male and female adolescents, and findings were synthesized using random-effects models. Potential sources of heterogeneity were examined by meta-regression and subgroup analyses. Results: Forty-seven studies from 19 countries comprising 28,033 male and 4,754 female adolescents were identified. The mean age of adolescents assessed was 16 years (range, 10–19 years). In male adolescents, 2.7% (95% CI 2.0%–3.4%) had a diagnosis of psychotic illness; 10.1% (95% CI 8.1%–12.2%) major depression; 17.3% (95% CI 13.9%–20.7%) ADHD; 61.7% (95% CI 55.4%–67.9%) conduct disorder; and 8.6% (95% CI 6.4%–10.7%) PTSD. In female adolescents, 2.9% (95% CI 2.4%–3.5%) had a psychotic illness; 25.8% (95% CI 20.3%–31.3%) major depression; 17.5% (95% CI 12.1%–22.9%) ADHD; 59.0% (95% CI 44.9%–73.1%) conduct disorder; and 18.2% (95% CI 13.1%–23.2%) PTSD. Metaregression found higher prevalences of ADHD and conduct disorder in investigations published after 2006. Female adolescents had higher prevalences of major depression and PTSD than male adolescents. Conclusion: Consideration should be given to reviewing whether health care services in juvenile detention can address these levels of psychiatric morbidit

2 Stakeholder engagement for innovation management and entrepreneurial development: A meta-analysis
مشارکت سهامداران برای مدیریت نوآوری و توسعه کارآفرینی: یک فراتحلیل-2020
This paper reviews contemporary studies in entrepreneurship literature related to innovation management (IM), stakeholder engagement (SE), and entrepreneurial development (ED), using bibliometric techniques and longitudinal statistical analysis of 1059 articles published in the Journal of Business Research (JBR) and other relevant business and management journals indexed in Scopus from 1974 until July 2020. We have employed a structured literature review and meta-analysis to explore the emerging research patterns in prospective observational studies encompassing the field of ED, SE, and IM. Our findings suggest that dynamics of the interaction of SE, IM, and ED are shaping the scholarship of academic research in entrepreneurship. Our meta-analysis reaffirms that contemporary research conducted at the intersection of SE, IM, and ED indicates the consolidation of these tenets in future research in entrepreneurship leading to an integrative view. Finally, we present future research directions at the intersection of SE, IM, and ED for entrepreneurship research.

3 Comparison of banking innovation in low-income countries: A meta-frontier approach
مقایسه نوآوری بانکی در کشورهای کم درآمد: یک رویکرد فرامرزی-2019
Financial innovation is a crucial factor behind many of the improvements in the financial sector that directly affect the economy in a positive way. Financial innovation may also alter financial intermediation and increase reliability and transparency. Research has demonstrated that levels of financial innovation are similar among high-income countries; however, research has shown that financial development differs substantially in low income countries regardless of the economic size, suggesting that financial innovation may also differ. This study evaluated the levels of financial innovation and the determinants of innovation within the low-income countries. In particular, a new two-step meta-frontier approach was constructed to estimate technology gap ratios, and a censored model was built to establish their determinants. The results show that low-income countries do in fact vary greatly in terms of financial innovation. Competition, financial inclusion and banking access constitute major determinants of financial innovation.

4 CNAVER: A Content and Network-based Academic VEnue Recommender system
CNAVER: سیستم توصیه گر دانشگاهی VEnue مبتنی بر شبکه و محتوا-2019
The phenomenon of rapidly developing academic venues poses a significant challenge for researchers: how to recognize the ones that are not only in accordance with one’s scholarly interests but also of high significance? Often, even a high-quality paper is rejected because of a mismatch between the research area of the paper and the scope of the journal. Recommending appropriate scholarly venues to researchers empowers them to recognize and partake in important academic conferences and assists them in getting published in impactful journals. A venue recommendation system becomes helpful in this scenario, particularly when exploring a new field or when further choices are required. We propose CNAVER: A Content and Network-based Academic VEnue Recommender system. It provides an integrated framework employing a rank-based fusion of paper-paper peer network (PPPN) model and venue-venue peer network (VVPN) model. It only requires the title and abstract of a paper to provide venue recommendations, thus assisting researchers even at the earliest stage of paper writing. It also addresses cold start issues such as the involvement of an inexperienced researcher and a novel venue along with the problems of data sparsity, diversity, and stability. Experiments on the DBLP dataset exhibit that our proposed approach outperforms several state-of-the-art methods in terms of precision, nDCG, MRR, accuracy, F − measuremacro, average venue quality, diversity, and stability.

5 A meta-analytic study of the impact of Lean Production on business performance
یک مطالعه تحلیلی متا روی تاثیر تولید تکیه ای روی عملکرد تجاری-2018
Lean Production (LP) is one of the most common initiatives in Operations Management that firms adopt to boost their competitiveness. The purpose of this paper is to examine the extant research on the relationship between LP and business performance (BP). The study analyses the data from 30 articles published from 2000 to 2016 that meet two targeted criteria, that they have: (i) empirically analysed the relationship between LP, or any measure of LP, and at least one measure of BP, and (ii) reported the effect size of the relationship between LP and BP measured with Pearsons correlation coefficients or related methods. Distinctions are made between two different performance outcomes (financial and market) and six LP practices. Using the Hunter and Schmidt (2004) meta-analysis based correlations approach, the obtained results show that a positive and moderate relationship exists between aggregate level LP and aggregate level business performance (r ̅´ = 0.31). There is also a positive relationship with market performance, but not with financial performance. Only three individual practices are statistically related to business performance (Process Control and Improvement, Workforce Development, and Customer Focus). The countrys level of economic development is also found to act as a moderating variable in several of the studied relationships and to have a greater effect in Emerging Economies than in Advanced Economies.

6 Electronic word of mouth and hotel performance: A meta-analysis
تبلیغ شفاهی الکترونیک و عملکرد هتل: یک تحلیل متا-2018
This study synthesizes existing empirical results about the relationship between electronic word of mouth (eWOM) and hotel performance via meta-analysis. Based on estimates from 25 articles, the average eWOM valence-based elasticity is estimated to be 0.888, whereas the average volume-based elasticity is 0.055. A hierarchical linear model is applied to uncover five aspects that explain variations in eWOM elasticities: research setting, data structure, variable measurement, model specification, and research outlet. The estimation results highlight several significant aspects affecting elasticity, such as year of study, geographic setting, panel data structure, data frequency, performance measurement, control of price variable, and function form. Finally, implications are provided for researchers and hoteliers.

7 A meta-analysis of how signaling affects learning with media
یک تحلیل متا روی چگونگی اثرگذاری علامت دهی روی یادگیری با رسانه-2018
The signaling effect states that learners profit from cues that highlight the organization of specific relevant information within materials. This meta-analysis includes 103 studies and N = 12,201 participants. 139 retention and 70 transfer performance measures were used to determine separate mean effect sizes. Cognitive load, motivation/affect, learning time, and eye-tracking data were included as dependent variables to explain possible effect mechanisms. Additionally, nine possible moderators (e.g., type of signaling) were identified. The retention (g+ = 0.53, 95% CI [0.42, 0.64]) and transfer (g+ = 0.33, 95% CI [0.22, 0.43]) sizes support the positive effect of signaling on motivation/affect, learning time, and learning-relevant fixations. Cognitive load was significantly reduced. In contrast to the expertise reversal effect hypothesis, prior knowledge was not identified as a moderator of the signaling effect. The results were interpreted using media learning theories. Recommendations for future studies are included herein.

8 تقلب در شفافیت در ارزیابی های عملکرد: چه زمانی و چرا انگیزه صحت، اغراق عمدی در بازخورد را توضیح می دهد
سال انتشار: 2018 - تعداد صفحات فایل pdf انگلیسی: 16 - تعداد صفحات فایل doc فارسی: 68
تحقیق حاضر نشان می دهد که مدیران به صورت غیر موثری با بازخورد منفی ارتباط برقرار می کنند چون آنها از تقلب در شفافیت رنج می برند که باعث می شود تا آنها درمورد اینکه چگونه کارکنان به صورت دقیق بازخورد خود را مشاهده می کنند اغراق کنند. ما بیان می کنیم که این تقلب ها به این دلیل پدید می آیند که مدیران به حدکافی برای دخالت کردن در تفکر کوشا که دقتی را که آنها با آن با بازخورد منفی کارکنان ارتباط برقرار می کنند انگیزه ندارند. شش مطالعه (تعداد 1883 نفر) با استفاده از ارزیابی های واقعی عملکرد درداخل یک سازمان و ارزیابی نقشهای ایفا شده با دانشجویان، فارغ التحصیلان و شرکت کننده های آنلاین رشته MBA، نشان می دهد که تقلب ها در شفافیت وقتی که بازخورد منفی باشد قوی تر است (مطالعات 1 تا 2) که آنها توسط تمایل و گرایش کارکنان تحریک نمی شوند (مطالعه 3) و به این دلیل اتفاق می افتند که مدیران به حد کافی انگیزه ندارند که دقیق باشند (مطالعات a4 و c4). به علاوه، این مطالعات نشان می دهند که تقلب ها در شفافیت توسط ارتباط غیر مستقیم تر با مدیر و اینکه چگونه دخالت های مختلف می توانند برای کاهش این اثرات استفاده شوند تحریک می شوند (مطالعات a4 تا c4). یک تحلیل متای داخلی شامل 11 مطالعه از ترسیم کننده فایل (تعداد 1887 نفر) وجود یک اندازه تاثیر متوسط که عاری از گرایش و تمایل این مقاله است را آشکار کرد.

9 Comparison of reading performance on screen and on paper: A meta-analysis
مقایسه عملکرد خواندن روی صفحه و روی کاغذ: یک تحلیل متا-2018
This meta-analysis looked at 17 studies which focused on the comparison of reading on screen and reading on paper in terms of reading comprehension and reading speed. The robust variance estimation (RVE)- based meta-analysis models were employed, followed by four different RVE meta-regression models to examine the potential effects of some of the covariates (moderators) on the mean differences in comprehension and reading speed between reading on screen and reading on paper. The RVE meta-analysis showed that reading on paper was better than reading on screen in terms of reading comprehension, and there were no significant differences between reading on paper and reading on screen in terms of reading speed. None of the moderators were significant at the 0.05 level. In the meanwhile, albeit not significant, examination of the p-values for the difference tests prior to 2013 and after 2013 respectively (not shown here) indicated that the magnitude of the difference in reading comprehension between paper and screen followed a diminishing trajectory. It was suggested that future meta-analyses include latest studies, and other potential moderators such as fonts, spacing, age and gender.

10 Resilience and Big Five personality traits: A meta-analysis
انعطاف پذیری و پنج عامل بزرگ شخصیت: متا تجزیه و تحلیل-2018
The current review synthesized studies investigating the relationships between resilience and Big Five person ality traits and aimed to investigate how the relationships vary according to the two types of resiliency, psy chological resilience and ego-resiliency. Thirty studies with a total sample size of 15,609 met the inclusion criteria to be used for the current meta-analysis. Results indicated that overall, estimated average correlation coefficients for resilience were: r = −0.46 with Neuroticism, r = 0.42 for Extraversion, r = 0.34 for Openness, r = 0.31 for Agreeableness, and r = 0.42 for Conscientiousness. When comparing the differences between the two types of resiliency, a stronger negative relationship with Neuroticism, and stronger positive relationships with Openness and Agreeableness were obtained with ego-resiliency, compared with trait resilience. However, there was a lack of homogeneity in effect sizes across studies especially for ego-resilience. Directions for future research regarding resilience and the limitations of present research are discussed.
