Effect of proactive personality on career adaptability of higher vocational college students: the mediating role of college experience.

For higher vocational students, the college stage is an important period in their career development, and the college experience plays an important role in the relationship between their proactive personality and career adaptability, which in turn has a significant impact on their future career development. From the perspective of social cognitive career theory and taking 476 vocational students as samples, this paper explores the mediating role of college experience between proactive personality and career adaptability of vocational college students. The college experience scale is revised for higher vocational students, and it is verified to have good reliability and validity. SPSS and Amos were used to conduct correlation analysis，and the PROCESS macro was used for mediating effect analysis. The results show that the college experience of vocational students plays a partial mediating role in the effect of proactive personality on career adaptability. This work innovatively uses social cognitive career theory to explore the role of college experience in the relationship between proactive personality and career adaptability among vocational students. The theoretical models are established and empirical verification is conducted, confirming that higher vocational students' college experience can affect their career adaptability. These results provide empirical evidence for vocational colleges to improve the career guidance of college students, and intervention measures are proposed to enhance students' career adaptability during school years, thus promoting their sustainable development.

It Is Not Bad to Be the Big Fish in a Small Pond: Revisiting the Double-Edged Sword Model of College Students' Perceived Overqualification.

School psychologists are concerned about underperforming students; however, a recent study calls attention to a group of college students who believe themselves to outperform other students: students who perceive themselves as overqualified. In this study, we revisited the double-edged sword model of college students' perceived overqualification (POQ) by untangling the mediating mechanism between POQ, learning engagement, and life satisfaction. We also tested the interactions between the growth mindset and POQ. Two questionnaire surveys were conducted and attained some different results from previous studies: (1) POQ positively predicted learning engagement via the mediation of career aspiration and performance-approach goals but not performance-avoidance goals; (2) The positive effects of POQ on career aspirations, performance-approach goals, and learning engagement were weakened by the growth mindset; (3) The relationship between POQ and life satisfaction was nonsignificant. Relative deprivation negatively mediated this relationship, while generalized self-efficacy positively mediated this relationship. These findings enriched our understanding of how POQ may affect college students' learning and well-being; in addition, we also provided initial evidence that a growth mindset is less beneficial for members of advantaged groups in academic settings. Based on our findings, we offered practical suggestions regarding POQ students in colleges.

The Development of an Interpersonal Stressors Scale: Identifying Self-Imposed and Other-Imposed Interpersonal Stressors.

While there has been research focused on interpersonal relationships and their impact on stress and well-being, no instrument has been developed to comprehensively evaluate interpersonal stressors. This research sought to develop and validate an Interpersonal Stressors Scale (ISS) for Chinese college students through three studies. Focus groups were used to generate the initial item pool (Study 1). Then two large samples (N1 = 511; N2 = 330) were collected to explore the factor structure of the ISS and subsequently examine its reliability and validity estimates (study 2 and 3). Initial results indicated a model with 27 items and five first-order factors (interaction difficulty, behaving as expected, social criticism, relationship maintenance, and indebtedness avoidance) as well as two second-order factors (self-imposed stressors and other-imposed stressors) with strong psychometric properties. Criterion-related validity estimates indicated these two kinds of stressors were both associated with stress while having different relationships with general anxiety, depression, social anxiety, interpersonal satisfaction, and self-efficacy in social interactions. The nature and function of the structure for the ISS were discussed as well as the practical and research implications.

Validating the Experiences in Close Relationships-Relationship Structures Scale among Chinese Children and Adolescents.

The Experiences in Close Relationships-Relationship Structures (ECR-RS) scale is designed to capture attachment among diverse relational contexts (e.g., parents, friends). Although the ECR-RS has begun to be applied to children and adolescents, its psychometric properties among children and adolescents are not well-known, especially concerning second-order structural validity, measurement invariance, and longitudinal predictive validity. To fill this gap, the current research examined the ECR-RS among 3,184 Chinese students (9- to 18-year old) using cross-sectional and longitudinal (6 months) data. The results demonstrated generally acceptable composite and test-retest reliabilities, and acceptable second-order structural validity. In addition, the measurement invariance of the ECR-RS held across time, relational contexts, and school levels to varying degrees. Furthermore, using a partial invariance model, we depicted the cross-sectional trajectory of attachment scores across relational contexts and school levels. Finally, attachment was associated concurrently with the Big-Five personality traits in theoretically meaningful ways and longitudinally predicted depression, anxiety, stress, and self-esteem after controlling for age, gender, and pretest scores. In conclusion, the Chinese ECR-RS has proven to be a valuable instrument for future research among children and adolescents.

What is the impact of granulocyte colony-stimulating factor (G-CSF) in subcutaneous injection or intrauterine infusion and during both the fresh and frozen embryo transfer cycles on recurrent implantation failure: a systematic review and meta-analysis?

BACKGROUND: Among recurrent implantation failure (RIF) patients, the rate of successful implantation remains relatively low due to the complex etiology of the condition, including maternal, embryo and immune factors. Effective treatments are urgently needed to improve the outcomes of embryo transfer for RIF patients. In recent years, many researchers have focused on immunotherapy using granulocyte colony-stimulating factor (G-CSF) to regulate the immune environment. However, the study of the G-CSF for RIF patients has reached conflicting conclusions. The aim of this systematic review and meta-analysis was performed to further explore the effects of G-CSF according to embryo transfer cycle (fresh or frozen) and administration route (subcutaneous injection or intrauterine infusion) among RIF patients. METHOD: The PubMed, Embase and Cochrane Central Register of Controlled Trials (CENTRAL) databases were searched for literature published from the initial to October 2020. The meta-analysis, random-effects model and heterogeneity of the studies with I2 index were analyzed. Stata 15 was used for statistical analysis. RESULTS: A total of 684 studies were obtained through the databases mentioned above. Nine RCTs included 976 RIF patients were enrolled in this meta-analysis. Subgroup analysis indicated that G-CSF improved the clinical pregnancy rate for both the fresh and frozen embryo transfer cycles (fresh RR: 1.74, 95% CI: 1.27-2.37, I2 = 0.0%, n = 410; frozen RR: 1.44, 95% CI: 1.14-1.81, I2 = 0.0.%, n = 366), and for both subcutaneous injection and intrauterine infusion (subcutaneous RR: 1.73, 95% CI: 1.33-2.23, I2 = 0.0%, n = 497; intrauterine RR: 1.39, 95% CI: 1.09-1.78, I2 = 0.0%, n = 479), but the biochemical pregnancy rate of the RIF group was also higher than that of the control group (RR: 1.85, 95% CI: 1.28-2.68; I2 = 20.1%, n = 469). There were no significant differences in the miscarriage rate (RR: 1.13, 95% CI: 0.25-5.21: I2 = 63.2%, n = 472) and live birth rate (RR: 1.43, 95% CI: 0.86-2.36; I2 = 52.5%; n = 372) when a random-effects model was employed. CONCLUSION: The administration of G-CSF via either subcutaneous injection or intrauterine infusion and during both the fresh and frozen embryo transfer cycles for RIF patients can improve the clinical pregnancy rate. However, whether G-CSF is effective in improving livebirth rates of RIF patients is still uncertain, continued research on the utilization and effectiveness of G-CSF is recommended before G-CSF can be considered mainstream treatment for RIF patients.

Rigorous microlens design using vector electromagnetic method combined with simulated annealing optimization.

In this paper, finite-aperture diffractive optical element with its critical dimension smaller than illumination wavelength is modeled and optimized using an integrated method. This method employs rigorous analysis model based on Finite Difference Time Domain (FDTD), and simulated annealing (SA) global search algorithm. Numerical results reveal that the diffraction efficiency of the 8-step microlens quickly climbs to its global optimum along with the optimization process, which manifests its global search ability. The design algorithm and implementation are discussed in details. Considering its time consuming efficiency and global search ability, our method provides valuable reference value in practical multistep microlens design.
