Effects of the need fulfillment given by opposite-sex friends on breakup considerations: A moderated mediation model.

The purpose of this study was to investigate the impact of need fulfillment given by opposite-sex friends (NFOF) on breakup considerations, the mediating role of love commitment in this relationship, and the moderating role of need fulfillment given by romantic partners (NFRP). A total of 334 unmarried individuals in romantic relationships from Northwest China were invited to participate in the study. The findings revealed the following: (1) NFOF significantly and positively predicted breakup considerations. (2) This relationship is mediated by love commitment (3) The association between NFOF and breakup considerations was moderated by NFRP (in terms of the first mediation path). Specifically, those who hold higher levels of NFRP are appreciably buffered against the negative impact of NFOF on love commitment. These findings emphasize the crucial role of NFOF and NFRP in shaping love commitment and breakup considerations. Moreover, our research has important realistic implications: NFOF, as a trigger, has a negative effects the quality of romantic relationships and leads to breakup considerations. And, the key to maintaining a romantic relationship is to focus on their partners' need fulfillment as much as possible and increasing the level of their love commitment.

Effects of thriving at work on employees' family role performance: A moderated mediation model.

Objective: Existing research has demonstrated that thriving at work has a positive effect on work performance, but little is known about how thriving at work affects family role performance. Based on the work-home resource model, this study examines the impact mechanism of thriving at work on family role performance. Methods: This paper uses an experience sampling method to conduct a 5-day daily study of 151 married employees in Northwest China, and the data were analyzed using a multilevel linear model. Results: We find that thriving at work positively affects family role performance partly through the mediating effect of work-family enrichment at the individual level. Moreover, family-supportive supervisor behavior moderates the relationship between thriving at work and work-family enrichment. Through work-family enrichment, family-supportive supervisor behavior also moderates the indirect relationship between thriving at work and family role performance. Specifically, the higher the level of family-supportive supervisor behavior, the stronger the indirect effect of thriving at work on family role performance through work-family enrichment. Conclusion: Previous research has focused more on the effects of thriving at work within the work domain, suggesting that thriving at work can have a positive impact on work outcomes. However, only a few studies have examined the positive relationship between thriving at work and family role performance from the perspective of employees' positive psychological resources. This paper explores the positive effects of thriving at work on family role performance based on a resource flow perspective and identifies its potential boundary conditions. This study enriches the theoretical research on the relationship between thriving at work and family role performance. Additionally, it provides a new foothold and research perspective on improving work-family enrichment.

Preparation, characterization and application of rod-like chitin nanocrystal by using p-toluenesulfonic acid/choline chloride deep eutectic solvent as a hydrolytic media.

Chitin nanocrystal (ChiNC) was fabricated based on p-toluenesulfonic acid -choline chloride deep eutectic solvent treatment. The obtained ChiNC was about 12-44 nm in width and 206-399 nm in length. The crystalline structure and the functional groups of ChiNC were maintained during the preparation process. Moreover, porcine pancreas lipase (PPL) was successfully immobilized onto the ChiNC to form the immobilized PPL (PPL@ChiNC). The resulting PPL@ChiNC has enzyme loading and activity recovery of 35.6 mg/g and 82.5%, respectively. The thermal stability, pH and temperature adaptabilities of PPL@ChiNC was improved, comparing with free PPL. The demonstrated DES treatment process was efficient for ChiNC preparation and the as-prepared ChiNC exhibited great potentials in biocatalysis and biomedical field.

Impact of hydrophilic catheters on urinary tract infections in people with spinal cord injury: systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: To identify randomized controlled trials comparing the use of hydrophilic and nonhydrophilic catheters for intermittent catheterization (IC) in patients with spinal cord injury (SCI), and to perform a meta-analysis evaluating the occurrence of hematuria and urinary tract infection (UTI). DATA SOURCES: We searched the following electronic databases to identify studies: EMBASE (1991 to August 2011), PubMed (1991 to August 2011), Cochrane Library (no date restriction), China National Knowledge Infrastructure (no date restriction), and the Chinese Biomedical Literature Database (no date restriction). STUDY SELECTION: Randomized controlled trials, parallel-control, crossover-control, and prospective cohort studies that assessed morbidity associated with the use of hydrophilic catheters and nonhydrophilic catheters in patients after SCI were included. DATA EXTRACTION: Data extraction was performed using standardized forms of the Cochrane Collaboration. Methodologic quality was independently assessed by 2 reviewers using the Downs and Black instrument. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for dichotomous data. DATA SYNTHESIS: Five studies involving 508 subjects; 462 subjects completed the study and were included in this meta-analysis. There was a significantly lower incidence (OR=.36; 95% CI, 24%-54%; P<.0001) of reported UTIs in the hydrophilic-treated group compared with the nonhydrophilic-treated group. Hematuria was also reported significantly less in the hydrophilic catheter group than in the nonhydrophilic catheter group (OR=.57; 95% CI, 35%-92%; P=.001). CONCLUSIONS: This meta-analysis found UTIs and hematuria less frequently associated with the use of hydrophilic-coated catheters for IC in patients with SCI. These findings support the use of hydrophilic catheters in this patient population.
