A meta-analytic investigation of problem gambling and self-harm: A causal inference perspective.

Problem gambling may be an underappreciated treatment target for reducing self-harm. Multivariate studies examining the relationship between problem gambling and self-harm have returned inconsistent results, perhaps due to insufficient power or differences in study quality. We conducted a series of meta-analyses examining the effect of problem gambling on self-harm outcomes of varying severity. We assessed the sensitivity of results to study characteristics, publication bias, and influential cases. To highlight threats to causal inference, we evaluated each study for residual confounding bias. In total, two types of meta-analyses were adequately powered: those assessing (a) the effect of problem gambling (binary) on suicide ideation and (b) problem gambling (binary) on suicide attempt (k = 14 unique studies between the two meta-analyses). For both meta-analyses, we found a positive, statistically significant average effect of problem gambling on the respective self-harm outcome. We did not detect any influential studies among these two meta-analyses, nor residual confounding. However, these findings are limited by the overall quality of included literature. PET-PEESE analysis detected substantial potential publication bias in the main results, with both meta-analytic effects being reduced to statistical nonsignificance. All included studies also used a cross-sectional design for their analysis of interest, thus simultaneity bias cannot be ruled out. While these findings suggest there is an appreciable relationship between problem gambling and at least two forms of self-harm (suicide ideation and attempts), well-designed longitudinal research is needed to make more firm conclusions.

A meta-analytic investigation of the potential for plant volatiles and sex pheromones to enhance detection and management of Lepidopteran pests.

Effective early detection, monitoring and management methods are critical for reducing the impacts of insect pests in agriculture and forestry. Combining host plant volatiles with sex pheromones could enhance trapping methodologies, whilst the use of non-host volatiles could improve the effectiveness of pest management through repellency effects. In this meta-analysis approach, we analysed 51 studies that used electroantennograms (EAG), wind tunnels and/or field traps to evaluate the antennal and behavioural responses of Lepidoptera to sex pheromones combined with attractant or repellent plant volatiles. Proposed attractant plant volatiles had a positive association with female Lepidoptera responses to sex pheromone, but effects on males were highly variable, with unexpected repellency reported in some studies. Proposed repellent plant volatiles were significantly or near-significantly negatively associated with male attraction to sex pheromones but were scarcely studied. Sub-group analysis identified that male responses to sex pheromone were reduced when the dose of attractant plant volatile relative to sex pheromone was increased. Green-leaf volatiles were associated with the strongest positive effects for males in field traps. Multiple-compound attractant plant volatile blends were less effective than single compounds in field studies. Our analysis demonstrates, (i) the potential value of combining host plant volatiles with sex pheromones to capture females rather than only males, (ii) the importance of identifying appropriate host plant volatiles and optimal relative doses, and (iii) the potential for non-host plant volatile use in pest management strategies.

The interplay of sustainability, corporate green accounting and firm financial performance: a meta-analytical investigation

PurposeThis study uses a meta-analysis approach to analyse the impact of applying corporate green accounting practices as vital sustainable development tools on firm performance. This study aims to examine the moderating effects of country-specific variables and characteristics on the association between corporate green accounting and firm performance.Design/methodology/approachThree databases were used for a meta-analysis of 68 independent studies involving 19,625 subjects conducted over 25 years from 1996 to 2020.FindingsThe results show that corporate green accounting positively affects firm performance, but country-specific variables do not moderate this association. The positive association between corporate green accounting and firm performance was enhanced when it was measured in terms of environmental costs. Subgroup analyses revealed that study characteristics are significant source of heterogeneity in the corporate green accounting indicators-firm performance association.Practical implicationsThe findings suggest that firms should strategise to integrate environmental costs into their respective financial accounting frameworks, which would help managers justify the contribution of their firms towards environmental protection.Social implicationsAccessing accurate and timely information on corporate environmental functioning can assist national policymakers in framing appropriate legislation on environmental protection and sustainable development.Originality/valueAlthough meta-analysis has been used previously in accounting research (Guthrie and Murthy, 2009; Alcouffe et al., 2019), to the best of the authors’ knowledge, this is the first study to use a meta-analytical technique to examine the impact of corporate green accounting on firm performance.

Facial expression recognition deficits in frontotemporal dementia and Alzheimer's disease: a meta-analytic investigation of effects of phenotypic variant, task modality, geographical region and symptomatic specificity.

Deficits in social cognition may be present in frontotemporal dementia (FTD) and Alzheimer's disease (AD). Here, we conduct a qualitative synthesis and meta-analysis of facial expression recognition studies in which we compare the deficits between both disorders. Furthermore, we investigate the specificity of the deficit regarding phenotypic variant, domain-specificity, emotion category, task modality, and geographical region. The results reveal that both FTD and AD are associated with facial expression recognition deficits, that this deficit is more pronounced in FTD compared to AD and that this applies for the behavioral as well as for language FTD-variants, with no difference between the latter two. In both disorders, overall emotion recognition was most frequently impaired, followed by recognition of anger in FTD and by fear in AD. Verbal categorization was the most frequently used task, although matching or intensity rating tasks may be more specific. Studies from Oceania revealed larger deficits. On the other hand, non-emotional control tasks were more impacted by AD than by FTD. The present findings sharpen the social cognitive phenotype of FTD and AD, and support the use of social cognition assessment in late-life neuropsychiatric disorders.

The effects of conjugated linoleic acid supplementation on anthropometrics and body composition indices in adults: a systematic review and dose-response meta-analysis.

Prior meta-analytic investigations over a decade ago rather inconclusively indicated that conjugated linoleic acid (CLA) supplementation could improve anthropometric and body composition indices in the general adult population. More recent investigations have emerged, and an up-to-date systematic review and meta-analysis on this topic must be improved. Therefore, this investigation provides a comprehensive systematic review and meta-analysis of randomised controlled trials (RCT) on the impact of CLA supplementation on anthropometric and body composition (body mass (BM), BMI, waist circumference (WC), fat mass (FM), body fat percentage (BFP) and fat-free mass (FFM)) markers in adults. Online databases search, including PubMed, Scopus, the Cochrane Library and Web of Science up to March 2022, were utilised to retrieve RCT examining the effect of CLA supplementation on anthropometric and body composition markers in adults. Meta-analysis was carried out using a random-effects model. The I2 index was used as an index of statistical heterogeneity of RCT. Among the initial 8351 studies identified from electronic databases search, seventy RCT with ninety-six effect sizes involving 4159 participants were included for data analyses. The results of random-effects modelling demonstrated that CLA supplementation significantly reduced BM (weighted mean difference (WMD): -0·35, 95 % CI (-0·54, -0·15), P < 0·001), BMI (WMD: -0·15, 95 % CI (-0·24, -0·06), P = 0·001), WC (WMD: -0·62, 95% CI (-1·04, -0·20), P = 0·004), FM (WMD: -0·44, 95 % CI (-0·66, -0·23), P < 0·001), BFP (WMD: -0·77 %, 95 % CI (-1·09, -0·45), P < 0·001) and increased FFM (WMD: 0·27, 95 % CI (0·09, 0·45), P = 0·003). The high-quality subgroup showed that CLA supplementation fails to change FM and BFP. However, according to high-quality studies, CLA intake resulted in small but significant increases in FFM and decreases in BM and BMI. This meta-analysis study suggests that CLA supplementation may result in a small but significant improvement in anthropometric and body composition markers in an adult population. However, data from high-quality studies failed to show CLA's body fat-lowering properties. Moreover, it should be noted that the weight-loss properties of CLA were small and may not reach clinical importance.

Being on the same page matters: A meta-analytic investigation of leader-member exchange (LMX) agreement.

Although leader-member exchange (LMX) theory offers a detailed account of leader-follower relationship building, the importance of LMX agreement as a theoretically meaningful relational phenomenon has received less attention. This has, in turn, limited scholarly understanding of its pivotal role in leader-follower relationships. We conducted a meta-analysis to synthesize the substantive implications of LMX agreement for leader-follower relationships and to further understand which factors may influence its variation across samples. Results from the random-effects metaregression analyses provided strong support for the moderating role of LMX agreement at the between-study level. Specifically, with higher levels of sample-level LMX agreement, the relationships between LMX and followers' task performance and organizational citizenship behaviors were stronger. Moreover, different national culture configurations (i.e., horizontal individualism vs. vertical collectivism) and changes in relationship tenure were significantly associated with LMX agreement. We also examined a host of methodological factors, which generally had a very limited impact on the study findings. Overall, these meta-analytic findings suggest LMX agreement should be considered as a key relational contingency in LMX theory, as it can help unlock the full potential of high-quality leader-follower relationships. Moreover, as a substantively meaningful phenomenon, its variation across situations is intricately related to contextual influences. Based on our theoretical integration and empirical synthesis, we discuss the implications for LMX theory and identify important directions for the next stages of LMX research.

Neural Plasticity Changes Induced by Motor Robotic Rehabilitation in Stroke Patients: The Contribution of Functional Neuroimaging.

Robotic rehabilitation is one of the most advanced treatments helping people with stroke to faster recovery from motor deficits. The clinical impact of this type of treatment has been widely defined and established using clinical scales. The neurofunctional indicators of motor recovery following conventional rehabilitation treatments have already been identified by previous meta-analytic investigations. However, a clear definition of the neural correlates associated with robotic neurorehabilitation treatment has never been performed. This systematic review assesses the neurofunctional correlates (fMRI, fNIRS) of cutting-edge robotic therapies in enhancing motor recovery of stroke populations in accordance with PRISMA standards. A total of 7, of the initial yield of 150 articles, have been included in this review. Lessons from these studies suggest that neural plasticity within the ipsilateral primary motor cortex, the contralateral sensorimotor cortex, and the premotor cortices are more sensitive to compensation strategies reflecting upper and lower limbs' motor recovery despite the high heterogeneity in robotic devices, clinical status, and neuroimaging procedures. Unfortunately, the paucity of RCT studies prevents us from understanding the neurobiological differences induced by robotic devices with respect to traditional rehabilitation approaches. Despite this technology dating to the early 1990s, there is a need to translate more functional neuroimaging markers in clinical settings since they provide a unique opportunity to examine, in-depth, the brain plasticity changes induced by robotic rehabilitation.

A meta-analytic investigation of the organizational identification – Job performance relationship in the frontlines

Organizational identification (OI) – which is defined as a sense of oneness with the organization – has consistently been found to increase frontline employee (FLE) job performance. However, whether these performance gains are uniform across different types of frontline jobs (e.g., retail clerks vs. financial advisors) and performance outcomes (e.g., behavioral vs. financial) has yet to be determined. Consequently, frontline managers lack the guidance necessary to decide whether or when they should prioritize investments in OI as a mechanism for achieving organizational performance goals. We begin to redress this knowledge gap through a meta-analytic investigation of the OI-FLE performance relationship, which reveals: (a) an overall positive effect of OI on FLE job performance, (b) job meaningfulness (i.e., job autonomy, skill variety and task significance) weakens the OI-FLE job performance relationship, and (c) this weakening is more pronounced in the case of behavioral and customer (but not financial) performance outcomes. Our study findings thus suggest retail managers should prioritize investments in OI when their goal is to promote desirable FLE behaviors and in situations where the work cannot be made meaningful due to job design constraints (e.g., when providing FLEs autonomy is not possible because the work must be performed in a prespecified manner at a predetermined time).

How Do Vape Advertising Campaigns Affect Consumers’ Vaping Tendency? A Meta-Analytic Investigation

The objective of this research is to help reconcile the mixed findings on the effect of vape advertising campaigns on consumers’ vaping tendency. In a meta-analysis of 43 papers (140 studies, with 77,452 observations; 33% women, 67% men; Mage = 30.5 years), this research shows that in situations where perceived risk is less salient (e.g., social media vs. traditional advertising, ads using picture-dominant vs. text-dominant cues, adolescents vs. adults, nonsmokers vs. smokers), the positive effect of vape advertising campaigns on consumers’ vaping tendency is stronger. In addition, this research provides evidence that vape advertising campaigns reduce, rather than increase, smokers’ tendency to quit smoking, which is contradictory to the claims made by vaping product manufacturers. The authors discuss the theoretical contributions of those findings and provide specific tools that policy makers can use to combat the influence of vape advertising campaigns. Potential limitations and future research directions are also discussed.

Association Between Psychological Capital and Subjective Wellbeing: a Systematic Review and Meta-analytic Investigation

This paper aims to perform a systematic review and meta-analytic investigation of previous empirical studies by examining and synthesizing the strength of the association between psychological capital and subjective well-being and trying to understand the heterogeneity across the studies by potential moderators. Electronic searches of literature on psychological capital and subjective well-being were performed via Scopus, google scholar, web of Science, research gate, etc., and SLR was done as per PRISMA guidelines. The random-effect model was used to compute necessary statistics like effect size, moderating effects, publication bias, and heterogeneity in the meta-essential program. The findings of this meta-analytic study revealed a large, significant, and positive correlation between psychological capital and subjective well-being (r=0.53; k= 42; 95% CI= 0.47- 0.59; P&lt; 0.001). The effect size varied in the presence of moderators. This meta-analytic examination overcomes the research heterogeneity by synthesizing the correlation of all individual studies on psychological capital and subjective well-being to produce the correct and precise academic conclusion which will help further in the development of new hypotheses. One of the major limitations of this meta-analytic study is that it has utilized only empirical and quantitative studies. Additionally, all studies were collected only from a few electronic database searches like Google Scholar, research gate, web of Science, Scopus, etc. which resulted in a limited number study for the analysis. The findings of this Meta-analysis make some administrative recommendations for recognizing the importance of psychological capital to improve the subjective well-being of employees. Accordingly, the organization will either recruit employees having psychological capital/ resources or train them to acquire or enhance psycap with the motive to maintain higher SWB.

Let me make mathematics and music together: A meta-analysis of the causal role of music interventions on mathematics achievement

ABSTRACT This research aims to conduct a fixed-effects meta-analysis to unpack the causal role of music interventions on mathematics achievement. Findings indicated that music interventions had a small to moderate positive effect on mathematics achievement (N = 77,595, k = 245, g = 0.36, p < 0.01, 95% CI [0.34, 0.38]). Mathematics skills, instructional mathematical content, types of music interventions, and age were significant moderators, whereas development status was not a significant moderator for this meta-analysis. The most crucial result was that studies using music-mathematics integrated intervention produced a large effect size. This study can be considered interesting in terms of revealing that a significantly strong and positive transfer in mathematics learning was only achieved when used mathematics and music together in the learning environment. Consequently, the current research is regarded to have laid some groundwork for further meta-analytic investigations as it provides detailed, up-to-date, and useful evidence on this issue.

How do GHRM practices influence firms’ economic performance? A meta-analytic investigation of the role of GSCM and environmental performance

This meta-analysis of 138 effect sizes from 75 studies examines the effect of green human resource management (GHRM) practices on organisations’ economic performance (ECP). The study also considers the mediating role of environmental performance (EP) and green supply chain management (GSCM) in the relationship between GHRM and ECP, including contextual and methodological moderators.The results demonstrate that GHRM is positively related to ECP both directly and indirectly through EP and GSCM. Some contextual (industry type, individualism, masculinity, and long-term orientation dimensions of national culture) and methodological factors (the number of GHRM dimensions) moderate the relationships surrounding GHRM.Our findings underline the relevance of the effective alignment between GHRM practices and the distinct role of different GHRM practices in promoting ECP. We also highlight that national culture issues could shape GHRM effectiveness and the importance of the effective implementation of GHRM practices for understanding the role of contextual and methodological moderators.

The Way We Play in the Sand: A Meta-Analytic Investigation of Sand Therapy, Its Formats, and Presenting Problems

ABSTRACT Sand therapy is a group of expressive arts interventions that is implemented with a variety of age groups that present to therapy with any number of chief complaints. In this study, we sought to establish an overall effect size for sand therapy, its efficacy with a variety of presenting problems, and the impact moderator variables may have had on effect size. For this meta-analysis, 36 studies were included, which yielded a Hedges’ g of 1.165. Additionally, meta-analyses were conducted on several different presenting problems including anxiety (k = 7, g = 1.425), anger (k = 5, g = .760), depression (k = 7, g = 1.071), parent–child relationship issues (k = 5, g = 3.932), and self-esteem (k = 6, g = 1.588). The impact of moderator analyses was conducted which indicated that sand therapy was as effective in group formats (k = 11, g = 1.073) as it was in individual settings (k = 7, g = 1.285). Additionally, age groups were analyzed, which indicated that sand therapy had high effect sizes that were roughly the same for adults (k = 14, g = 1.414), adolescents (k = 8, g = 1.035), and children (k = 14, g = 1.112). We discuss clinical implications for the use of sand therapy and further research suggestions.
