Abstract. Which data to analyze, and how, are fundamental questions of all empirical research. As there are always numerous flexibilities in data-analytic decisions (a “garden of forking paths”), this poses perennial problems to all empirical research. Specification-curve analysis and multiverse analysis have recently been proposed as solutions to these issues. Building on the structural analogies between primary data analysis and meta-analysis, we transform and adapt these approaches to the meta-analytic level, in tandem with combinatorial meta-analysis. We explain the rationale of this idea, suggest descriptive and inferential statistical procedures, as well as graphical displays, provide code for meta-analytic practitioners to generate and use these, and present a fully worked real example from digit ratio (2D:4D) research, totaling 1,592 meta-analytic specifications. Specification-curve and multiverse meta-analysis holds promise to resolve conflicting meta-analyses, contested evidence, controversial empirical literatures, and polarized research, and to mitigate the associated detrimental effects of these phenomena on research progress.

Significant Factors

Objective The present meta-analysis sought to determine significant factors that predict trust in artificial intelligence (AI). Such factors were divided into those relating to (a) the human trustor, (b) the AI trustee, and (c) the shared context of their interaction. Background There are many factors influencing trust in robots, automation, and technology in general, and there have been several meta-analytic attempts to understand the antecedents of trust in these areas. However, no targeted meta-analysis has been performed examining the antecedents of trust in AI. Method Data from 65 articles examined the three predicted categories, as well as the subcategories of human characteristics and abilities, AI performance and attributes, and contextual tasking. Lastly, four common uses for AI (i.e., chatbots, robots, automated vehicles, and nonembodied, plain algorithms) were examined as further potential moderating factors. Results Results showed that all of the examined categories were significant predictors of trust in AI as well as many individual antecedents such as AI reliability and anthropomorphism, among many others. Conclusion Overall, the results of this meta-analysis determined several factors that influence trust, including some that have no bearing on AI performance. Additionally, we highlight the areas where there is currently no empirical research. Application Findings from this analysis will allow designers to build systems that elicit higher or lower levels of trust, as they require.

This chapter focuses on one particular aspect of education for refugee children, namely science education, in the various contexts these refugees encounter, especially when immersed in cultures away from their mother language and bridges with the family culture. The universal character of natural sciences makes is precious for these displaced children. Renovating science education has been the subject of international efforts and remarkable innovative pilot projects since two decades A number of such projects, in various developing or developed countries, are reported here, with the positive impact which was observed in multi-cultural contexts. Although none of these projects yet dealt with extreme situations such as refugee camps, the lessons learned suggest to act in this direction, using the pedagogical ressources now available in many languages, as well as a potential contribution of the scientific community.

This chapter illustrates meta-analysis, which is a specific type of literature review, and more precisely a type of research synthesis, alongside traditional narrative reviews. Unlike in primary research, the unit of analysis of a meta-analysis is the results of individual studies. And unlike traditional reviews, meta-analysis only applies to: empirical research studies with quantitative findings hat are conceptually comparable and configured in similar statistical forms. What further distinguishes meta-analysis from other research syntheses is the method of synthesizing the results of studies — i.e. the use of statistics and, in particular, of effect sizes. An effect size represents the degree to which the phenomenon under study exists.

The clinical need for lesbian, gay, bisexual, and queer (LGBQ+) affirmative psychotherapies has been widely recognized; however, empirical research on the outcomes of such psychotherapies is limited. This chapter begins by offering definitions and delineating four key themes of LGBQ+ affirmative psychotherapies. The authors conceptualize LGBQ+ affirmative psychotherapies not as sexual orientation group specific but rather as considerations and practices that can be applied with all clients. The chapter then summarizes a search for studies to attempt a meta-analysis and discusses limitations and directions for research based on this search. The chapter ends by delineating diversity considerations and recommending therapeutic practices for advancing affirmative psychotherapy with clients of all sexual orientations.

Talking Cure

Although writing about the real relationship has existed from the beginnings of the talking cure,” it is only in recent years that empirical research has focused on this phenomenon. The real relationship is the personal relationship between patient and therapist marked by the extent to which each is genuine with the other and perceives/experiences the other in ways that are realistic. The strength of the real relationship is determined by both the extent to which it exists and the degree to which it is positive or favorable. In this chapter, a meta-analysis is presented on the association between the real relationship and the outcome of psychotherapy. Summed across 16 studies, this meta-analysis revealed a moderate association with outcome (r =.38, 95% confidence interval [.30, .47], p<.001, d = 0.80, N = 1,502 participants). This real relationship–outcome association was independent of the type of outcome studies and of the source of the measure. We also present frequent measures of the real relationship, limitations of the research, and patient contributions. The chapter concludes with diversity considerations and practice recommendations for developing and strengthening the real relationship.

Healing Phase

Treatment of severe burn wounds presents a daunting medical challenge, and novel approaches promoting healing and reducing scarring are highly desirable. The application of mesenchymal stem/stromal cells (MSCs) has been suggested as a novel treatment. In this paper, we present systematic reviews of pre-clinical and clinical studies of MSC therapy for second- or third-degree thermal burn wounds. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, the PubMed and Embase databases were searched, and interventional studies of MSC therapy using rodent models (21 studies) or human burn patients (three studies) were included in the pre-clinical and clinical reviews, respectively, where both overall outcome and wound-healing-phase-specific methodologies and effects were assessed. The pre-clinical studies demonstrated a promising effect of the application of MSCs on several wound healing phases. The clinical studies also suggested that the MSC treatment was beneficial, particularly in the remodeling phase. However, the limited number of studies, their lack of homogeneity in study design, relatively high risk of bias, lack of reporting on mode of action (MOA), and discontinuity of evidence restrict the strength of these findings. This comprehensive review presents an overview of available methodologies to assess the MOA of MSC treatment for distinct wound healing phases. Furthermore, it includes a set of recommendations for the design of high-quality clinical studies that can determine the efficacy of MSCs as a therapy for burn wounds.

This chapter presents the overall conclusion that emerges from the book, which is that empirical findings may play a role in shaping legal responses to segregation and diversity in schools, but the bulk of current research increasingly becomes irrelevant. The legal system and researchers appear to be moving in opposite directions in what they identify as problematic and what to do about it. This chapter sorts through the lessons learned about the legal system’s evaluation of empirical research. It highlights the problematic nature of legal approaches, which now focus on remaining neutral/color-blind with regard to racial disparities. It then details how the legal system can better benefit from research that addresses racial and ethnic disparities.

While a number of studies have reviewed empirical research on individuals’ entrepreneurial intentions (EIs), very little is known about the cumulative performance of frequently used constructs and their direct and indirect relationships with EI. This research has exposed 123 usable empirical studies of EI to weight- and meta-analyses to determine the cumulative performance of various frequently explored relationships. A generic research model of the antecedents of EI is proposed on that basis. The outcomes of this research and its limitations have practical and theoretical implications for future entrepreneurship research.
