This meta-analysis has two aims: a) to address the main effects of social constructivist mobile learning environments on learners’ knowledge acquisition and their academic achievements b) to address potential factors regarding design principles and instructional methods for successful social constructivist mobile environments in a blended learning context. We selected 24 articles that meet the inclusion criteria: empirical studies implementing mobile learning in a blended environment using social constructivism approach. The selected studies are not identical in terms of instructional strategies, tools and devices, period and student’s expertise level. These factors lead to variations in the magnitude of the effect sizes. The review reveals that there is a positive effect of mobile learning on the knowledge acquisition, learners’ achievements, attitudes and motivation despite the high cognitive load. This is shown through the combined effect size. A last remarkable finding related to retention is that students in such environments fulfill their academic tests, but remember less the acquired knowledge after a retention period.

The paper was shaped around the pivotal question: Is SE a sound and scientific field of research? The question has given a critical tone to the paper and has also helped to bring out some of the controversial debates in the realm of SE. The paper was organized under five main discussions to be able to provide a scientific answer to the research question: (1)<b> </b>is “social entrepreneurship” an oxymoron?, (2) the characteristics of SE knowledge, (3) sources of social entrepreneurship knowledge, (4) SE knowledge: structure and limitations and (5) contributing epistemology-making concepts for SE.<b> </b>Based on the sections,<b> </b>the study relied on the relevant philosophical schools of thought in <i>Epistemology </i>(e.g. <i>Empiricism</i>, <i>Rationalism</i>, <i>Skepticism</i>, <i>Internalism</i> vs. <i>Externalism</i>,<i> Essentialism, Social Constructivism</i>, <i>Social Epistemology, etc.</i>) to discuss these controversies around SE and proposes some solutions by reviewing SE literature. Also, to determine the governing linguistic discourse in the realm of SE, which was necessary for our discussion,<i> Corpus of Contemporary American English (COCA)</i> for the first time in SE studies was used. Further, through the study, SE buzzwords which constitute SE terminology were derived and introduced to help us narrowing down and converging the thoughts in this field and demarking the epistemological boundaries of SE. The originality of the paper on one hand lies in its pioneering discussions on SE epistemology and on the other hand in paving the way for a construction of sound epistemology for SE; therefore in many cases after preparing the philosophical ground for the discussions, it went beyond the prevalent SE literature through meta-analysis to discuss the cases which were raised. The results of the study verified previously claimed embryonic pre-paradigmatic phase in SE which was far from a sound and scientific knowledge, although the scholarly endeavors are the harbingers of such a possibility in the future which calls for further mature academic discussion and development of SE knowledge by the SE academia.

Abstract Recent surveys of the literature on climate change and migration emphasize the important diversity of outcomes and approaches of the empirical studies. In this paper, we conduct a meta-analysis in order to investigate the role of the methodological choices of these empirical studies in finding some particular results concerning the role of climatic factors as drivers of human mobility. We code 51 papers representative of the literature in terms of methodological approaches. This results in the coding of more than 85 variables capturing the methodology of the main dimensions of the analysis at the regression level. These dimensions include authors' reputation, type of mobility, measures of mobility, type of data, context of the study, econometric methods, and last but not least measures of the climatic factors. We look at the influence of these characteristics on the probability of finding any effect of climate change, a displacement effect, an increase in immobility, and evidence in favor of a direct vs. an indirect effect. Our results highlight the role of some important methodological choices, such as the frequency of the data on mobility, the level of development, the measures of human mobility and of the climatic factors as well as the econometric methodology.

This study conducts a meta-analysis of empirical studies that have measured the spatial scale of industrial clustering. Two types of scales are examined: the peak scale (at which cluster effects are maximized) and the maximum reach (beyond which cluster effects are undetectable). We find that the scale varies significantly by the unit of analysis, industry sector, country of study, and the sources of cluster effects examined (e.g., knowledge spillovers, localization, and urbanization). Planners and policy makers should tailor the geographies embodied in cluster strategies to match the specific local needs and circumstances.

Purpose: Mini-dental implants (MDIs) have been used to support and retain overdentures, providing patients with a less invasive placement procedure. Although lucrative, the use of MDIs to retain a maxillary overdenture is still not an established treatment modality. This systematic review aims to answer the question: Do mini-implant-retained maxillary overdentures provide a satisfactory treatment outcome for complete edentulism? Methods: A systematic search for relevant articles was conducted to include articles published until April 2021 in the following electronic databases: CINAHL, Cochrane, EMBASE, PubMed, and Web of Science. All empirical studies evaluating the biological, survival, or patient-reported outcomes after placing mini-implant-retained overdentures in maxilla were considered for inclusion. The risk of bias was assessed by utilizing the Joanna Briggs Institute critical appraisal checklist. Study screening and data extraction were conducted by three reviewers independently. Results: The electronic search retrieved 1276 titles after omitting duplicates. Twenty articles were considered for full-text review, of which six studies were included in this systematic review. The included studies evaluated a total of 173 participants with a mean age of 66.3 years. The overall mini-implant survival rate was 77.1% (95% CI: 64.7–89.5%) with a mean follow-up time of 1.79 years (range: 6 months to 3 years). Implant survival differed significantly when comparing complete and partial palatal coverage overdentures. Those with complete palatal coverage exhibited less bone loss overall compared to partial coverage overdentures. Participants of all studies reported an increase in the quality of life and in satisfaction after rehabilitation treatment with MDIs. Conclusions: The survival rate of mini-implants retaining an overdenture in the maxilla was observed to be lower than the values reported for traditional implants in the literature. Improvements were observed in all aspects in terms of patient satisfaction, quality of life, oromyofunction, and articulation after the treatment.

Crime And Delinquency

In recent years, criminologists have begun to focus more closely on how certain biosocial and/or neuropsychological factors may influence criminal and delinquent behaviour. One factor that is emerging as a potentially important correlate of such behaviour is Attention Deficit — often combined with hyperactivity — Disorder (ADD and/or ADHD). The results of the growing body of empirical literature assessing this link are, however, inconsistent. The present study subjects this body of research to a ‘meta-analysis' — or, ‘quantitative synthesis' — to establish both the overall effect of ADHD on crime and delinquency and the degree to which this relationship is conditioned by methodological factors across empirical studies. The analyses reveal a fairly strong association between measures of ADHD and criminal/delinquent behaviour. Nevertheless, these effects are not invariant across certain salient methodological characteristics. The implications for criminological theory and correctional policy are discussed.

Orthopedic Patients

Background and objective: There is evidence that opioid initiation post-surgery is contributing to the problem of chronic misuse and/or abuse of over the counter medications in the community, and that orthopedic patients may be particularly at risk. The aim of the systematic review with meta-analysis was to identify research that examined opioid use at 3, 6, and 12 months post-operatively by previously opioid naïve orthopedic surgery patients.Design, databases, and data treatment: A searched review with meta-analysis was undertaken. Eight databases were search. Meta-analyses conducted at all three time points (3 months, 6 months, and 12 months).Results: The search yielded 779 records, and after screening, 13 papers were included in meta-analysis. Results provide strong evidence that post-operative opioid use amongst the opioid naïve is a real effect (7 percent at 3 months, 4 percent at 6 months, and 2 percent at 12 months). A Z-test for overall effect revealed strong evidence that this proportion was nonzero for opioid use at 3, 6, and 12 months (p 0.001 for all time points). A small but significant proportion of opioid naïve patients who are prescribed opioids remain on these medications up to 12 months post-operatively.Conclusions: The nature of the studies included in the meta-analysis were varied, hence subanalyses regarding surgery type, characteristics of the patient group or other potential factors that might influence the progression to longer term opioid use after these surgeries could not be explored. Given this, further research in this area should explore such specific orthopedic subgroups.

The aim of the study is to conduct a structured review of literature on the antecedents of organizational ambidexterity by reconciling the mixed outcomes produced by the extant literature. This study offers some theoretical insights into the divergent views of authors on these factors by analysing the empirical studies done in the literature. This paper systematically analyses the extant literature on the factors affecting organizations' ambidexterity, using meta-analysis and the theory, context, characteristics, and methodology (TCCM) framework. Forty-three research papers across various journals that discussed the correlation of the variables with organizational ambidexterity were selected. The sample size was 17,383, and 20 variables were selected for the analysis. The results revealed that two variables showed high levels of heterogeneity. The implications of this study are relevant to the present business scenario and of substantial interest to scholars, as they provide a more detailed understanding of the very foundation of organizational ambidexterity.

Factors Influencing

This review examines 12 years of research by focusing on the following question: What are the factors that influence self-efficacy in an online learning environment? There has been a plethora of research concerning self-efficacy. However, few works have focused on the sources of self-efficacy in online-learning environments. Systematic searches of numerous online data-bases published between 2005 and 2017, which covered factors influencing self-efficacy in online learning context, resulted in the investigation of 25 studies. The data were extracted, organized and analyzed using a narrative synthesis. Results revealed that various factors improved self-efficacy and provided evidence of significant sources of self-efficacy in the context of online learning. Moreover, the investigation provides guidance for further research in designing online learning environments to enhance the self-efficacy of learners.
