A novel adaptive e-learning model based on Big Data by using competence-based knowledge and social learner activities
یک مدل تطبیقی جدید یادگیری الکترونیکی مبتنی بر داده های بزرگ با استفاده ازدانش مبتنی بر شایستگی و فعالیت های یادگیرنده اجتماعی-2018
The e-learning paradigm is becoming one of the most important educational methods, which is a deci sive factor for learning and for making learning relevant. However, most existing e-learning platforms offer traditional e-learning system in order that learners access the same evaluation and learning con tent. In response, Big Data technology in the proposed adaptive e-learning model allowed to consider new approaches and new learning strategies. In this paper, we propose an adaptive e-learning model for providing the most suitable learning content for each learner. This model based on two levels of adaptive e-learning. The first level involves two steps: (1) determining the relevant future educational objectives through the adequate learner e-assessment method using MapReduce-based Genetic Algo rithm, (2) generating adaptive learning path for each learner using the MapReduce-based Ant Colony Optimization algorithm. In the second level, we propose MapReduce-based Social Networks Analysis for determining the learner motivation and social productivity in order to assign a specific learning rhythm to each learner. Finally, the experimental results show that the presented algorithms implemented on Big Data environment converge much better than those implementations with traditional concurrent works. Also, this work provides main benefit because it describes how Big Data technology transforms e-learning paradigm.

Investigation of the reach and effectiveness of a mentoring program for youth receiving outpatient mental health services
بررسی رسایی و سودمندی یک برنامه ترببیتی برای جوانان دریافت کننده خدمات سرپایی سلامت ذهنی -2018
This research investigated the reach and effectiveness of Great Life Mentoring (GLM), a program for youth receiving outpatient mental health services in which community volunteers are paired with participating youth in one-to-one mentoring relationships. Study participants included 91 youth served by GLM over an approximately 15-year period and a randomly selected sample of 400 youth who received mental health care from the same agency but did not participate in GLM. Although youth involved in GLM were similar to their peers on most assessed characteristics, they also differed in some ways at initiation of treatment services. For example, GLM-served youth were younger, more likely to be from a very-low-income family, and more likely to have a primary diagnosis of attention deficit/hyperactivity disorder (ADHD) and a secondary diagnosis. The average duration of the mentoring relationships established for the 91 GLM youth, including both those that had ended and those that were still ongoing, was about three years (M = 35.49 months), with only a small percentage (7.7%) having ended in less than one year. Longer-term mentoring relationships were predicted by being from a low-income family (rather than a very-low-income family), having a mentor with a higher education level, and not having a primary diagnosis of ADHD. When comparing change over time on clinician-ratings on the Childrens Global Assessment of Functioning for propensity-score-matched groups of GLM (n = 66) and non-GLM (n = 66) youth, the GLM youth showed significantly more favorable change than their matched counterparts after the point in time at which they were paired with a mentor through the program. Relative to their matched counterparts, GLM youth also were less likely to have an unplanned and client-initiated ending of treatment (33.9% vs. 56.3%) and more likely to have a planned ending of treatment (32.3% vs. 18.8%).
A supportive adult may be the difference in homeless youth not being trafficked
یک فرد بزرگسال حامی می تواند در جوانان بی خانمان تردد نکننده متفاوت باشد-2018
Purpose To explore the factors that differentiate trafficked homeless youth from not-trafficked homeless youth. Methods From November 2015–February 2017, homeless youth served by Covenant House New Jersey, aged 18–22, received a trafficking assessment. Youth were stratified based upon trafficking experience, and their responses to demographic and social history questions were examined for association with trafficking occurrence. Results Of 344 participants, 9.6% had a trafficking experience. Having an Individualized Education Program/504 plan was, for the first time in anti-trafficking literature, associated with a trafficking experience in bivariable analysis. IEP/504 plans are developed for school-aged children whose ability to succeed in traditional educational formats is challenged by learning, social, or functional problems. In the multivariable analysis, a history of arrest was associated with being trafficked while the presence of a supportive adult was associated with not being trafficked. Gender was not associated with a trafficking experience. Conclusions This study is the largest to specifically assess homeless youths demographic and social variables for association with trafficking experience. Homeless youth who are and are not trafficked share similar life experiences, but those with a supportive adult in their life had lower odds of being trafficked. Building upon our research, future investigations exploring order of occurrence will elucidate the risk factors for and protective factors against trafficking among homeless youth, contributing to evidence-based prevention efforts.
Regulating market entry of low-cost private schools in Sub-Saharan Africa: Towards a theory of private education regulation
تنظیم ورود مدارس خصوصی هزینه - پایین به بازار در آفریقای صحرایی: به سوی یک نظریه درباره مقررات آموزش خصوصی-2018
This study provides a comparative assessment of policies governing private schools in twenty countries in Sub-Saharan Africa. Findings suggest that current regulatory systems are failing to adequately address the negative externalities and failures of private schooling markets. Insufficient capacity on the part of governments is a contributor to uneven policy implementation and creates opportunities for rent-seeking and corruption. Onerous market entry regulations offer constraints on the growth of official private education markets, but facilitate growth in unofficial markets if demand for education is not being fully met by the supply of government service provision, restricting the government’s ability to provide adequate oversight of private providers.

Do dropout and environmental factors matter? A directional distance function assessment of tunisian education efficiency
آیا ترک تحصیل و عوامل محیطی مهم هستند؟ یک بررسی روی تابع فاصله هدایتی کارآمدی آموزش تونس-2018
The purpose of this paper is to investigate the education efficiency in Tunisia based on a sample of secondary schools. We place some special focus on schools resources and corresponding dropout levels. We use the Directional Distance Function (DDF) methodology to simultaneously deal with bad outputs and non-discretionary inputs. Our assessment is based on Data Envelopment Analysis (DEA) method. The data is extracted from the Program for International Student Assessment (PISA) 2012 survey. We generate four models through various inputs and outputs specifications while considering dropout levels and education environment. Our empirical study reveals strong influence between education performance and both school infrastructure and educational resources. In particular, the financial constraints seem to have real effect on the dropout levels.

Quality of higher education in Kenya: Addressing the conundrum
کیفیت آموزش عالی در کنیا: بررسی یک معما-2018
Despite the consensus amongst all stakeholders of the critical need for action in the higher education sector in Kenya, national and institutional drives for quality have had limited impact. This study aims to assess the barriers to enhancing quality in Kenyan higher education, drawing on interviews, observations and documentary analysis as part of a three year study. Three types of barrier are identified in the data: resources (staffing and infrastructure), governance (organisational structures and stakeholder participation) and pedagogical culture (social hierarchies and approaches to teaching, curriculum and assessment). On the basis of these findings, it is argued that a ‘three-pronged’ response is needed: reforms in policy and practice must address simultaneously the material conditions of universities, the forms of institutional organisation, and the cultural relations of teaching and learning.

A big data approach to the concordance of the toxicity of pharmaceuticals in animals and humans
یک رویکرد داده های بزرگ برای تطابق سمیت داروها در حیوانات و انسانها-2018
Although lack of efficacy is an important cause of late stage attrition in drug development the shortcomings in the translation of toxicities observed during the preclinical development to observations in clinical trials or post-approval is an ongoing topic of research. The concordance between preclinical and clinical safety observations has been analyzed only on relatively small data sets, mostly over short time periods of drug approvals. We therefore explored the feasibility of a big-data analysis on a set of 3,290 approved drugs and formulations for which 1,637,449 adverse events were reported for both humans animal species in regulatory submissions over a period of more than 70 years. The events reported in five species – rat, dog, mouse, rabbit, and Cynomolgus monkey - were treated as diagnostic tests for human events and the diagnostic power was computed for each event/species pair using likelihood ratios. The animal-human translation of many key observations is confirmed as being predictive, such as QT prolongation and arrhythmias in dog. Our study confirmed the general predictivity of animal safety observations for humans, but also identified issues of such automated analyses which are on the one hand related to data curation and controlled vocabularies, on the other hand to methodological changes over the course of time.

Strengthening stakeholder buy-in and engagement for successful exploration and installation: A case study of the development of an area-wide, evidence-based prevention and early intervention strategy
استحکام بخشیدن به خرید و مشغولیت ذی نفع برای بررسی و راه اندازی موفق: یک مطالعه موردی روی توسعه یک جلوگیری گسترده و مبتنی بر شواهد و راهبرد مداخله قبلی-2018
Background The implementation of evidence-based programmes (EBPs) designed to improve outcomes for children and young people and prevent disadvantage is an increasingly important international policy imperative. However, the integration of EBPs into existing service settings and systems is a complex and multifaceted undertaking. Methods A process evaluation was conducted to appraise the design and development of a large-scale, area-based, prevention and early intervention initiative. This initiative, called Youngballymun, consisted of five service strategies comprising a range of EBPs (e.g. the Incredible Years Programme, Highscope) targeted at children and young people and their families (from birth to 20 years). The initiative was designed to promote the development, adoption and implementation of EBPs within routine children and youth services in a disadvantaged urban area in the Republic of Ireland. The analytical approach involved the systematic analysis and triangulation of data obtained from relevant documentation (e.g. programme manuals, meeting minutes), as well as a series of one-to-one interviews (n = 27) and six group discussions with key stakeholders (n = 29). Results Adopting aspects of an implementation stages framework (Fixsen, Naoom, Blase, & Friedman, 2005), we examined the key implementation stages of exploration and installation. Data gathering and needs assessment and strategic organisational development played an important role in implementation. However, resistance to innovation amongst local service providers emerged as a major challenge to implementation. Factors identified as crucial to overcoming this challenge and promoting stakeholder buy-in for innovation included: encouraging and supporting stakeholder engagement; and adopting a flexible approach to implementation planning. Conclusion Generating buy-in amongst stakeholders is central to ensuring a fit between innovative programmes and practices and the systems in which they are to be embedded. Some key lessons, such as the need for the active involvement of community-based service providers in the planning process at the earliest stages of implementation, are identified. The kinds of implementation strategies that may be used to address challenges to practice change and innovation, particularly stakeholder responsiveness to, and perceived compatibility of, EBPs, are discussed.

Japanese residential care quality and perceived competency in institutionalized adolescents: A preliminary assessment of the dimensionality of care provision
کیفیت مراقبت اقامتی ژاپنی ها و صلاحیت مشاهده شده در نوجوانان پناهگاهی: یک بررسی مقدماتی روی بُعدی بودن تامین مراقبت-2018
Although early institutionalization has been shown to have broad, detrimental effects on child developmental outcomes, there have been few attempts to systematic measure which aspects of the institution and caregiving environment associate with negative psychological outcomes. The current study uses a culturally and contextually modified early adolescent version of the Home Observation for Measurement of the Environment Inventory (EA-HOME-JP) in Japanese child welfare institutions (CWIs) to provide preliminary data on relevant variables in the caregiving environment that associate with domains of perceived self-competency. Forty-six children and young people (Agemean = 13 years 9 months) and their 35 primary caregivers from 11 CWIs were interviewed using EA-HOME-JP. Children and young people also self-reported on their perceived cognitive, physical, social competencies, and sense of self-worth. Participants within the same residential environments exhibited marked variation across each EA-HOME-JP subscale suggesting that the same rearing environment can be experienced differently by different individuals. Interestingly, EA-HOME-JP scores did not vary with care type (large-ward, middle-ward, and family-like), Instead, CWIs grouped within the same care type showed significant variation to one another on EA-HOME-JP subscales. Importantly, EA-HOME-JP scores, rather than care type, associated with aspects of competency (cognitive competency and sense of self-worth). As these findings are based on a small number of participants, they will require further replication in larger samples ascertained from other regions in Japan. Ultimately, these data may contribute to considerations over optimal packages of residential rearing in Japan.

Measuring tourism seasonality across European countries
سنجش فصلی بودن گردشگری دربین کشورهای اروپایی-2018
This paper will propose a general approach for the analysis and measurement of seasonality in tourism, based on an analysis of the pattern of seasonal swing, as a preliminary step for the assessment of seasonal amplitude. The seasonality of tourism demand across European countries will be analyzed and clusters of countries identified, which are based on a similarity of their seasonal pattern. After discussing the limitations of the most frequently used indices employed in the tourism literature, a new index for measuring seasonality in tourism will be suggested in order to measure seasonal amplitude. The latter takes into account the ordinal and cyclical structures of seasonal variations. The results demonstrate a strong connection between seasonal patterns and the spatial distribution throughout European countries, which may orient future policy actions for dealing with seasonality on a European level.
