Employee benefit availability, use, and subjective evaluation: A meta-analysis of relationships with perceived organizational support, affective organizational commitment, withdrawal, job satisfaction, and well-being.

Employee benefits constitute 38.1% of compensation costs, representing a sizeable investment in the workforce. Unlike other forms of support that depend on the actions of individuals throughout the organization, benefits can be changed through decisions at the highest level and influence employees throughout the company. Yet, the literature on benefits has been largely disjointed, resulting in theoretical ambiguity and practical questions about the role of employee benefit experiences in individual employee outcomes. To inform theory and practice, we organized the benefits literature using social exchange theory as a framework and conducted a meta-analysis on the relationships of employee benefit availability, use, and subjective evaluation with perceived organizational support, employee attitudes, and well-being. Our review (k = 134, N = 260,604) found unique relationships between the availability and subjective evaluation of employee benefits and affective organizational commitment, withdrawal intentions, job satisfaction, and well-being, with these relationships partially mediated by perceived organizational support. Benefit use contributed little to these outcomes beyond benefit availability and subjective evaluation. Benefit subjective evaluation was also more strongly related to most outcomes than were benefits availability and use. These relationships varied across types of benefits, with training benefits more strongly related to job satisfaction and health care and retirement benefits more strongly related to turnover intentions. Altogether, this meta-analysis integrates the empirical literature on employee benefits and highlights the implications of benefit experiences and types for the employee-organization relationship and employee well-being.

Meta-analysis of relationship between weaning age and daily weight gain of piglets in the farrowing and nursery phases

A systematic review of the literature was carried out to perform a meta-analysis to assess effects of age at weaning on the performance of piglets in the range of 14 to 42 days old. This step consisted in defining the databases and keywords to be employed in searching for papers for the meta-analysis. To that end, the databases Capes Publication Portal and Google Scholar were searched for researches published from 2001 to 2019. After the acceptance and exclusion criteria had been defined and applied, 28 papers were selected. The data were collected with Excel® software of Microsoft Office for later statistical analysis. Orthogonal polynomial contrasts were used and the linear and quadratic regression equations were fitted with hypotheses tested at the 5% significance level. The results confirmed the disadvantages of early weaning and the benefits of weaning at around 28 days old. In the farrowing phase, piglets weaned after 35 days had lower daily weight gain (DWG) (P =0.002) than those weaned at 27 days. The derivative of the regression of DWG while nursing on age revealed that a weaning age of 26.34 days yielded the maximum DWG among the ages assessed. After weaning, the maximum DWG was achieved by weaning piglets at 32.26 days. Given the performance of piglets in the farrowing and nursery phases, the results of this meta-analysis indicated the best weaning age was between 26 and 32 days.

A Systematic Review and Meta-analysis of Relationships Between Religiosity and Employees Constructive and Destructive Behaviors

There is substantial literature on the relationship of religiosity with constructive and destructive behaviors, and it is about time to consolidate the knowledge through a systematic review and meta-analysis among organizational members. For this, meta-analysis studies published between 2000 and 2018 were included with a total sample of 3714. Results show a weak and significant association between religiosity and employee' behavioral outcomes (ř = 0.07). Moreover, a relatively stronger relationship is reported with employees' constructive behavioral outcome (ř = 0.12). In contrast, a negative and insignificant relationship is reported with employees' destructive behavioral outcome (ř = - 0.03, LL = - 0.08 and UL = 0.02). Study limitation and direction for future research has been presented for this investigation.

Job crafting: A meta-analysis of relationships with individual differences, job characteristics, and work outcomes

Job crafting is a form of proactive work behavior that involves employees actively changing the (perceived) characteristics of their jobs, including behaviors aimed at increasing challenging and decreasing hindering job demands, as well as those directed at increasing structural and social job resources (Tims & Bakker, 2010). Research on job crafting has rapidly increased over the past decade, but findings have thus far not been quantitatively synthesized. We first integrate job crafting as conceptualized by Tims and Bakker (2010) with a more general theoretical model of proactive work behavior. Then, we present a meta-analysis (K=122 independent samples representing N=35,670 workers) of relationships between job crafting behaviors and their various antecedents and work outcomes derived from our model. We consider both overall and dimension-level job crafting relationships. Notably, overall job crafting was found to be strongly associated with proactive personality (rc=0.543), promotion regulatory focus (rc=0.509), and work engagement (rc=0.450). Differential results emerged when considering specific job crafting dimensions. For example, increasing challenging job demands was associated with other-rated work performance (rc=0.422), whereas decreasing hindering job demands was related to turnover intentions (rc=0.235). Beyond these zero-order relationships, a meta-analytic confirmatory factor analysis provides support for the operationalization of overall job crafting based upon the proposed dimensions, with the exception of decreasing hindering demands. Additionally, results of meta-analytic relative weights analyses speak to the unique relationships of all four job crafting dimensions with different work outcomes.

Festival attributes and perceptions: A meta-analysis of relationships with satisfaction and loyalty

Festivals provide economic, social and cultural benefits to the communities in which they occur, and contribute to event tourism and destination marketing. This research reports a meta-analysis of the festival literature to evaluate the factors that contribute to festival satisfaction and loyalty. Attributes were classified into six categories: activities, authenticity/uniqueness, concessions, environment, escape and socialization. The analysis revealed that festival activities (program, entertainment, thematic activities) and environment (atmosphere, convenience, facilities) are the most important determinants of satisfaction and loyalty. Two perceptions were evaluated: cost/value and service quality. The analysis revealed that cost/value is important for both satisfaction and loyalty, whereas service quality is relatively unimportant. Satisfaction with the festival is strongly related to loyalty. The findings suggest that festival planners should focus on providing an enjoyable program in a comfortable environment at a reasonable price. This strategy will cultivate repeat attendance and stimulate future visits to the festival destination.

Career adaptability: A meta-analysis of relationships with measures of adaptivity, adapting responses, and adaptation results

Career adaptability, a psychosocial resource for managing career-related tasks, transitions, and traumas, is a central construct in career construction theory and the field of vocational psychology. Based on the career construction model of adaptation, we conducted a meta-analysis to examine relationships of career adaptability with measures of adaptivity, adapting responses, adaptation results, and demographic covariates. Results based on a total of 90 studies show that career adaptability is significantly associated with measures of adaptivity (i.e., cognitive ability, big five traits, self-esteem, core self-evaluations, proactive personality, future orientation, hope, and optimism), adapting responses (i.e., career planning, career exploration, occupational self-efficacy, and career decision-making self-efficacy), adaptation results (i.e., career identity, calling, career/job/school satisfaction, affective organizational commitment, job stress, employability, promotability, turnover intentions, income, engagement, self-reported work performance, entrepreneurial outcomes, life satisfaction, and positive and negative affect), as well as certain demographic characteristics (i.e., age, education). Multiple regression analyses based on meta-analytic correlations demonstrated the incremental predictive validity of career adaptability, above and beyond other individual difference characteristics, for a variety of career, work, and subjective well-being outcomes. Overall, the findings from this meta-analysis support the career construction model of adaptation.

A meta-analysis of relationships between polychlorinated biphenyl exposure and performance across studies of free-ranging tree swallows (Tachycineta bicolor).

Habitats worldwide are increasingly being degraded by human activities, with environmental pollution representing a significant threat to species and ecosystems. The presence of persistent organic chemicals, such as polychlorinated biphenyls (PCBs), has generated concern. Captive experiments and field studies have reported some evidence for detrimental effects of PCB exposure, but also significant variation across studies and species. Here, I use a meta-analytical approach to combine findings across 10 studies investigating effects of PCBs on performance (e.g. reproductive success, offspring growth) in free-ranging tree swallows, a common bioindicator species that accumulates high levels of PCBs at some contaminated sites. Contrary to predictions, five complementary analyses revealed no significant negative association between PCB exposure and performance in tree swallows. In fact, in one analysis, increased PCB exposure was associated with improved reproductive success. Possible explanations for these findings include several limitations of field studies, variation in the toxicity of different PCB congener mixtures found across sites included in the analysis, and variation in the degree of tolerance of PCB exposure among species (with high tolerance found in tree swallows). At this point, the available evidence from field studies does not demonstrate negative impacts of PCB exposure on tree swallow performance.

Meta-analysis of relationship between extranodal tumor deposits and prognosis in patients with colorectal cancer

To investigate the relationship between extranodal tumor deposits and prognosis in patients with colorectal cancer. The literatures on extranodal tumor deposits and postoperative survival rate in patients with colorectal cancer published at home and abroad from 1990 to 2014 were retrieved in 15 English literature databases such as MEDLINE/PubMed, Web of Science, Directory of Open Access Journals(DOAJ), SpringerLink and Chinese literature databases such as Chinese Biomedical Literature Database CD-ROM, China National Knowledge Infrastructure (CNKI) Database with the internet platform of Yonsei University Library. After screening for inclusion, data extraction and quality assessment, meta-analysis was conducted by the Review Manager 5.3 software. There were 10 studies meeting the inclusion criteria for meta-analysis. The total sample size of the studies was 4 068 cases with ENTD(+) 727 cases, while ENTD(-) 3 341 cases. Meta analysis showed that 5-year overall survival rate and 5-year relapse-free survival rate were significantly lower in ENTD(+) group than those in ENTD(-) group (OR 0.27, 0.23; 95% CI:0.18 to 0.43, 0.16 to 0.34 respectively, both P=0.000); the 5-year overall survival rates were both significantly lower in ENTD(+) group as compared to ENTD(-) group for patients with N0 and N(+) colorectal cancer (both P<0.05). Extranodal tumor deposits is a poor prognostic factor of patients with colorectal cancer.

Creative and innovative performance: a meta-analysis of relationships with task, citizenship, and counterproductive job performance dimensions

Many studies have examined creative and innovative performance (CIP)–task performance, CIP–organizational citizenship behaviour (OCB), and CIP–counterproductive work behaviour (CWB) relationships in order to differentiate CIP from these established job performance dimensions. However, the overlap between CIP and these performance dimensions is still not clear due to mixed findings evident in the literature. To address this issue, we conducted a comprehensive meta-analytic review of empirical research into CIP–task performance, CIP–OCB, and CIP–CWB relationships derived from 39 studies and 40 independent samples. Overall, CIP was positively related to task performance (ρ = .55) and OCB (ρ = .56) and negatively related to CWB (ρ = −.23). We did not observe evidence suggesting that CIP measurement, rating source, OCB target, or CWB type moderated these relationships. Implications of our findings and directions for future research are discussed.

Meta-analysis of relationships between enteric methane yield and milk fatty acid profile in dairy cattle

Various studies have indicated a relationship between enteric methane (CH4) production and milk fatty acid (FA) profiles of dairy cattle. However, the number of studies investigating such a relationship is limited and the direct relationships reported are mainly obtained by variation in CH4 production and milk FA concentration induced by dietary lipid supplements. The aim of this study was to perform a meta-analysis to quantify relationships between CH4 yield (per unit of feed and unit of milk) and milk FA profile in dairy cattle and to develop equations to predict CH4 yield based on milk FA profile of cows fed a wide variety of diets. Data from 8 experiments encompassing 30 different dietary treatments and 146 observations were included. Yield of CH4 measured in these experiments was 21.5±2.46g/kg of dry matter intake (DMI) and 13.9±2.30g/kg of fat- and protein-corrected milk (FPCM). Correlation coefficients were chosen as effect size of the relationship between CH4 yield and individual milk FA concentration (g/100g of FA). Average true correlation coefficients were estimated by a random-effects model. Milk FA concentrations of C6:0, C8:0, C10:0, C16:0, and C16:0-iso were significantly or tended to be positively related to CH4 yield per unit of feed. Concentrations of trans-6+7+8+9 C18:1, trans-10+11 C18:1, cis-11 C18:1, cis-12 C18:1, cis-13 C18:1, trans-16+cis-14 C18:1, and cis-9,12 C18:2 in milk fat were significantly or tended to be negatively related to CH4 yield per unit of feed. Milk FA concentrations of C10:0, C12:0, C14:0-iso, C14:0, cis-9 C14:1, C15:0, and C16:0 were significantly or tended to be positively related to CH4 yield per unit of milk. Concentrations of C4:0, C18:0, trans-10+11 C18:1, cis-9 C18:1, cis-11 C18:1, and cis-9,12 C18:2 in milk fat were significantly or tended to be negatively related to CH4 yield per unit of milk. Mixed model multiple regression and a stepwise selection procedure of milk FA based on the Bayesian information criterion to predict CH4 yield with milk FA as input (g/100g of FA) resulted in the following prediction equations: CH4 (g/kg of DMI)=23.39 + 9.74 × C16:0-iso – 1.06 × trans-10+11 C18:1 – 1.75 × cis-9,12 C18:2 (R2=0.54), and CH4 (g/kg of FPCM)=21.13 – 1.38 × C4:0 + 8.53 × C16:0-iso – 0.22 × cis-9 C18:1 – 0.59 × trans-10+11 C18:1 (R2=0.47). This indicated that milk FA profile has a moderate potential for predicting CH4 yield per unit of feed and a slightly lower potential for predicting CH4 yield per unit of milk.

Meta-analysis of relationships between environmental factors and aboveground biomass in the alpine grassland on the Tibetan Plateau

Abstract. The Tibetan Plateau, known as the "world's third pole" for its extremely harsh and fragile ecological environment, has attracted great attention because of its sensitivity to global changes. Alpine grassland on the Tibetan Plateau has an important function in the global carbon cycle. Many studies have examined the effects of various environmental factors on biomass distribution. In this study, the relationships between the habitat parameters and the aboveground biomass (AGB) abundance on the Tibetan Plateau were examined through a meta-analysis of 110 field sites across the widely distributed alpine steppe and meadow. The obtained data were then analysed using the classification and regression tree model and the generalized additive model. The results showed that the AGB abundance in alpine steppe was positively correlated with six environmental factors, namely, soil organic carbon density of the top soil layer from 0 cm to 30 cm (SOC30 cm), longitude, mean annual precipitation (MAP), latitude, clay, and soil moisture. For the alpine meadow, five main factors were detected, namely, altitude, soil moisture, nitrogen, MAP, and mean annual temperature. The increased AGB abundance in the alpine steppe was associated with the increased SOC30 cm, MAP, and latitude, and the increased longitude resulted in decreased AGB abundance. For the alpine meadow, altitude and soil moisture showed strongly negative effects on AGB abundance, and soil nitrogen content was positively related to the AGB distribution across all examined sites. Our results suggest the combined effects of meteorological, topographic, and soil factors on the spatial patterns of AGB on the Tibetan Plateau.

A Data Warehouse of Muscle Characteristics and Beef Quality in France and A Demonstration of Potential Applications

The BIF-Beef (Beef Integrated and Functional Biology) database contains animal, carcass, muscle and meat data (331,745 entries) collected from 43 experiments over the last 20 years and a great number of variables (621) characterising muscles (fat and collagen contents, cross-section and types of fibres, metabolic activity), making it a relevant tool to relate muscle characteristics to beef quality. Wide variation was observed in all described traits according to muscle type, sex and breed. The BIF-Beef database was mainly composed of data from young bulls of late-maturing beef breeds, which is why live weight and carcass weights of the animals were greater, and beef was leaner and lighter than results from other existing databases. Average cross-sectional area of fibres was greater in Semitendinosus than in Longissimus thoracis muscle and, for Longissimus, greater in steers than in young bulls. Intramuscular fat content was in descending order: Charolais > Limousin > Blond d’Aquitaine and females > steers > young bulls. Semitendinosus muscle was less oxidative and contained more collagen than Longissimus muscle. Collagen content in Longissimus was higher in Charolais than in Blond d’Aquitaine and Limousin young bulls. Within the Charolais breed, collagen content in Longissimus was higher in young bulls and steers than in females. Longissimus samples from young bulls were less tender than from females. Based on the above results, this database is a prerequisite for meta-analysis of relationships between muscle characteristics and beef quality in the European context.
