BACKGROUND
There is a paucity of knowledge concerning the psychological variables that serve to facilitate the connection between physical activity and self-efficacy, and the factors capable of moderating these pathways. This study aimed to examine the relationship between physical activity and self-efficacy among college students, with a focus on the mediating effect of grit and the moderating effect of gender.
METHODS
This study recruited 3,228 undergraduate students from a university in Shanghai, China. They completed the General Self-Efficacy Scale, the Short Grit Scale, and the International Physical Activity Questionnaire. Statistical analysis was conducted using SPSS 26.0 and the Process v4.0 plugin.
RESULTS
Physical activity had both a direct effect on self-efficacy ( = 0.07, 95% CI [0.04-0.11]) and an indirect effect through the two dimensions of grit: perseverance of effort ( = 0.06, 95% CI [0.04-0.07]) and consistency of interest ( = 0.03, 95% CI [0.02-0.04]). The mediating effect explained 53.27% of the total effect. Furthermore, gender moderated the relationship between perseverance of effort and self-efficacy, with a stronger effect observed in males ( = 0.08, = 3.27, < 0.01).
CONCLUSION
The results revealed that grit is an underlying psychological mechanism that links physical activity and self-efficacy. Moreover, gender moderates the effect of perseverance of effort on self-efficacy, with a stronger effect observed in males. These findings have practical implications for educators to design tailored physical activity interventions that foster grit and self-efficacy among college students.

The Society for the Preservation of the Health of the Jewish Population (OZE) was an organisation dedicated to providing medical aid to Eastern European Jews ravaged by war, revolution, poverty and disease during and after World War I. The OZE's top priority was addressing the health needs of Jewish children and teaching mothers how to 'properly' raise their infants, as children were believed to be the backbone and future of the Jewish nation. Analysing the OZE's public-facing newspaper (People's Health), this paper examines how the OZE used reigning ideas in the Western European and North American scientific community around race and hygiene packaged in Yiddish to transform Jewish women into 'modern mothers'. Modernising maternity required Jewish women to be completely reliant on medical authority and relinquish traditional forms of childcare. At a time when Jews lived in different newly established nation-states of Eastern Europe, transforming maternity practices was part of a larger project started by Jewish physicians in the Russian Empire to unite Jews by defining them in national terms, replacing religious and parochial definitions. This paper uses discursive and gender analysis to explore how the OZE saw women's abilities (or not) to raise a healthy Jewish nation as a crucial part of Jewish national diaspora politics. Hence, this paper emphasises the political nature of a seemingly apolitical humanitarian project by uncovering how the image of a modern Jewish mother facilitated a vision of Jewish cohesion and perseverance through health.

OBJECTIVE
This investigation aimed to compare the neuropsychological dysfunctions of coronavirus (COVID-19)-recovered nurses to those of healthy nurses.
METHODOLOGY
The present research method was descriptive and causal-comparative, in which the statistical population consisted of nurses with a history of COVID disease and working in the COVID department of public hospitals in Isfahan city. The available method selected 30 nurses with a history of illness and compared them with 30 other nurses from the same hospitals. We collected data using the "go/no go" test, the Wisconsin card sorting test (WCST), and direct and inverted word reading tests. We also analyzed the collected data using multivariate analysis of variance.
RESULTS
The results showed a significant difference between nurses with a history of COVID disease and normal nurses in memory performance, the total error of the Wisconsin card sorting test, and the error of committing and inappropriately inhibiting the go/no go task (P < 0.01). However, there is no significant difference between the two groups in the number of classes, the error of perseveration in the Wisconsin test, or the reaction time of the go/no task (P < 0.05).
CONCLUSION
Therefore, the present study's results indicate that nurses recovering from COVID-19 perform worse than normal nurses in memory functions, cognitive flexibility, and response inhibition within one to three months of recovery.

Review
The first home visit (VAD) by a nurse from the medical-psychological center (CMP) for a patient who has been out of psychiatric care for a very long time, or who has never benefited from it, is decisive for the follow-up and continuity of care. The attitude and posture of the caregiver are decisive. VAD is an intrusion into a place of life, intimacy and suffering. It upsets a person who has walled himself into a shell, a cocoon, from which the fear of coming out is often massive. Anguish prevents any mobilization towards care. It takes a great deal of skill to create a bond of trust to initiate the idea of care.

Procrastination has a detrimental impact on academic performance, health, and subjective well-being. Previous studies indicated that grit was negatively related to procrastination. However, the underlying neural basis of this relationship remains unclear. To address this issue, we utilized voxel-based morphometry (VBM) and resting-state functional connectivity (RSFC) analysis to identify the neural substrates of how is grit linked to procrastination. Behavioral results showed that procrastination was negatively associated with grit. VBM analysis revealed that gray matter volume (GMV) in the left precuneus was positively associated with the consistency of interest (CI), a subcomponent of grit, while the right medial orbital frontal cortex (mOFC) was positively correlated with the perseverance of effort (PE), another subcomponent of grit. Moreover, the RSFC analysis indicated that both precuneus-medial superior frontal gyrus (mSFG) and precuneus-insula connectivity were positively related to CI, while the functional coupling of right mOFC with left anterior cingulate cortex (ACC) was positively related to PE. Importantly, the structural equation modeling (SEM) results were well suited for the influence of grit on procrastination via both self-regulation (mOFC-ACC) and motivation pathways (precuneus-mSFG, precuneus-insula). Together, these findings imply that self-regulation and motivation could be two neural circuits underlying the impact of grit on procrastination.

The aim of this study was to create and validate a ten-item Domain-specific Grit Scale for College Athletic Students (DGSCAS) to assess the level of grit among college athletic students. College athletic students from a single independent college located in a northern city in China (526 participants at time 1 and 589 participants at time 2) were assessed according to the scale. Various analyses were conducted in this study, including exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and measurement invariance analysis across different sex and birthplaces. The results of the EFA revealed two factors: consistency of interests and perseverance of effort. The CFA results demonstrated acceptable fit indices (x = 160.048, df = 34, x/df = 4.707, CFI = 0.983, TLI = 0.978, SRMR = 0.021, and RMSEA = 0.079). The scale exhibited satisfactory convergent validity and discriminant validity. The significant correlation of these factors with the Grit scale provided strong evidence of criterion-related validity. Measurement invariance analysis indicated that the scale performed consistently across different sex and birthplaces. Three limitations and corresponding recommendations were discussed, including sample heterogeneity, the lack of a unified test result as a criterion for predictive validity, and the cross-sectional design of the study. In conclusion, the DGSCAS is a practical and validated instrument that can be used to assess the level of grit among college athletic students in an educational context.

Is Conscientiousness a useful construct across cultures? Using the 2012 Program for International Student Assessment data, we examined whether perseverance, a measure of Conscientiousness, was related to achievement and truancy across 62 countries/regions ( > 470,000). We investigated whether these relationships were linear or curvilinear in nature and assessed the utility of item-level information. After establishing partial metric invariance of the perseverance measure across various countries/regions and cultural regions, our findings unveiled that perseverance consistently predicted both math achievement and truancy, with predominantly linear associations. Notably, among the five items of the Perseverance scale, the item reflecting one's tendency to give up easily in the face of challenges emerged as the strongest and most consistent predictor of math achievement. Further, country-level correlations between perseverance and both math achievement and truancy displayed contradictory patterns compared to individual-level correlations, suggesting the presence of biasing factors in how people respond to these measures. Nonetheless, it appears reasonable to conclude that measures of Conscientiousness are pan-cultural predictors of achievement and truancy. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The toxicity of inhaled particulate air pollution perseveres even at lower concentrations than those of the existing air quality limit. Therefore, the identification of safe and effective measures against pollutant particles-induced vascular toxicity is warranted. Carnosol is a bioactive phenolic diterpene found in rosemary herb, with anti-inflammatory and antioxidant actions. However, its possible protective effect on the thrombotic and vascular injury induced by diesel exhaust particles (DEP) has not been studied before. We assessed here the potential alleviating effect of carnosol (20 mg/kg) administered intraperitoneally 1 h before intratracheal (i.t.) instillation of DEP (20 μg/mouse). Twenty-four hours after the administration of DEP, various parameters were assessed. Carnosol administration prevented the increase in the plasma concentrations of C-reactive protein, fibrinogen, and tissue factor induced by DEP exposure. Carnosol inhibited DEP-induced prothrombotic effects in pial microvessels in vivo and platelet aggregation in vitro. The shortening of activated partial thromboplastin time and prothrombin time induced by DEP was abated by carnosol administration. Carnosol inhibited the increase in pro-inflammatory cytokines (interleukin-6 and tumor necrosis factor α) and adhesion molecules (intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin, and P-selectin) in aortic tissue. Moreover, it averted the effects of DEP-induced increase of thiobarbituric acid reactive substances, depletion of antioxidants and DNA damage in the aortic tissue. Likewise, carnosol prevented the decrease in the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) caused by DEP. We conclude that carnosol alleviates DEP-induced thrombogenicity and vascular inflammation, oxidative damage, and DNA injury through Nrf2 and HO-1 activation.

The following paper describes a steady-state model of concurrent choice, termed the active time model (ATM). ATM is derived from maximization principles and is characterized by a semi-Markov process. The model proposes that the controlling stimulus in concurrent variable-interval (VI) VI schedules of reinforcement is the time interval since the most recent response, termed here "the active interresponse time" or simply "active time." In the model after a response is generated, it is categorized by a function that relates active times to switch/stay probabilities. In the paper the output of ATM is compared with predictions made by three other models of operant conditioning: melioration, a version of scalar expectancy theory (SET), and momentary maximization. Data sets considered include preferences in multiple-concurrent VI VI schedules, molecular choice patterns, correlations between switching and perseveration, and molar choice proportions. It is shown that ATM can account for all of these data sets, while the other models produce more limited fits. However, rather than argue that ATM is the singular model for concurrent VI VI choice, a consideration of its concept space leads to the conclusion that operant choice is multiply-determined, and that an adaptive viewpoint-one that considers experimental procedures both as selecting mechanisms for animal choice as well as tests of the controlling variables of that choice-is warranted.

The Novelty-Seeking Model does not address the iterative nature of creativity, and how it restructures one's worldview, resulting in overemphasis on the role of curiosity, and underemphasis on inspiration and perseverance. It overemphasizes the product; creators often seek merely to express themselves or figure out or come to terms with something. We point to inconsistencies regarding divergent and convergent thought.
