The impact of deep learning based- psychological capital with ideological and political education on entrepreneurial intentions.

The aim of this study is to investigate the influence of psychological capital on college students' entrepreneurial intentions. Through a combination of relevant analysis and linear regression, the primary focus is on exploring the relationship between psychological capital and its four dimensions with entrepreneurial intentions. Firstly, the items in the psychological capital questionnaire were revised to align more closely with entrepreneurial contexts. Subsequently, the average deviations and standard deviations of each dimension of psychological capital were analyzed. Then, the correlation between psychological capital and entrepreneurial intentions was examined to explore the extent of their relationship. Finally, regression analysis was conducted on both psychological capital and entrepreneurial intentions, and utilizing a recurrent neural network model, the covariant relationship between entrepreneurial psychological capital and intentions was explored. The results indicated that the average scores for entrepreneurial self-efficacy, optimism, hope, and resilience were 3.91, 4.27, 4.19, and 4.15, respectively. The average value of psychological capital was 4.13, indicating a moderately high level. The correlation analysis between psychological capital and entrepreneurial intentions yielded a result of 0.562, indicating a moderate degree of correlation. The correlation coefficients of the four dimensions with entrepreneurial intentions were 0.390, 0.494, 0.531, and 0.467, respectively. The standardized coefficients for psychological capital and its four dimensions were 0.564, 0.382, 0.510, 0.536, and 0.468, all of which were statistically significant. Overall, psychological capital exhibited better predictive power for entrepreneurial intentions than its individual dimensions. The results from the deep learning model similarly demonstrated the positive role of psychological capital in entrepreneurial intentions, though the influence of ideological and political education (IPE) factors was relatively weaker. In conclusion, both psychological capital and IPE have a promotive effect on entrepreneurial intentions. This study provides a reference for the accurate evaluation of college students' entrepreneurial intentions.

Psychological capital variables as protective factors in indigenous youth experiencing homelessness.

Indigenous youth in the United States are at high-risk for experiencing homelessness related to adverse childhood experiences such as parental substance use and low educational attainment. Such experiences may lead to adverse physical and mental health issues; these youth also have positive attributes of psychological capita (hope, self-efficacy, resilience, optimism) that are related to health outcomes. The purpose of this secondary analysis was to describe demographic attributes and psychological capital in Indigenous youth experiencing homelessness (IYEH) who participated in a longitudinal intervention study related to safe sex behaviors and life satisfaction. From a total of 602, Indigenous participants (n = 111; mean age 21.25 ± 1.82 years) were recruited from drop-in centers in Austin, Texas and Columbus, Ohio. Data were collected immediately after the intervention and at 3- and 6-month intervals. For this analysis, only data collected at the final time-point were used. Valid scales with Cronbach alphas of 0.75-0.92 (Hope, Resilience, Optimism, Self-efficacy for Substance Refusal, Self-efficacy for Safer Sex, Safe Sex Behaviors, Social Connectedness, and Life Satisfaction) were used. The majority of the IYEH reported smoking, drinking, and using drugs. Psychological capital variables of hope, self-efficacy for negotiating safer sex, resilience, and optimism were significantly related to one another, but not to safe sex behaviors or intention to use condoms. Resilience and optimism were significantly related to social connectedness but not to other psychological capital variables. Life satisfaction was significantly associated with hope, resilience, and optimism. Findings have implications for further theory and research development.

Emerging adults' emotions toward their siblings with down syndrome.

BACKGROUND: Typically-developing siblings of individuals with Down Syndrome often experience complex emotions towards their sibling. This study explored how social support, personal resources (optimism, sense of coherence [SOC]), and individual variables (sex, religious affiliation, siblings' functionality) may impact emerging adult siblings' emotions toward their sibling with Down Syndrome. METHODS: Participants were 292 siblings of individuals with DS ranging in age from 18-27 (M=21.54, SD=2.50). Participants completed self-report questionnaires exploring optimism, SOC, support, and acceptance. RESULTS: Higher levels of support and optimism were positively associated with positive emotions, and higher SOC with lower levels of negative emotions. Siblings' functionality and religious affiliation interacted with variables to predict emotions. CONCLUSIONS: This study contributes to a greater understanding of how emotions may play a role in sibling relations during the emerging adulthood stage. It also provides unique insight into how religious affiliation may be associated with more positive outcomes for siblings.

An outside individual option increases optimism and facilitates collaboration when groups form flexibly.

Voluntary participation is a central yet understudied aspect of collaboration. Here, we model collaboration as people's voluntary choices between joining an uncertain public goods provisioning in groups and pursuing a less profitable but certain individual option. First, we find that voluntariness in collaboration increases the likelihood of group success via two pathways, both contributing to form more optimistic groups: pessimistic defectors are filtered out from groups, and some individuals update their beliefs to become cooperative. Second, we reconcile these findings with existing literature that highlights the detrimental effects of an individual option. We argue that the impact of an outside individual option on collaboration depends on the "externality" of loners - the influence that those leaving the group still exert on group endeavors. Theoretically and experimentally, we show that if collaboration allows for flexible group formation, the negative externality of loners remains limited, and the presence of an individual option robustly aids collaborative success.

The bidirectional relationships of optimism and pessimism with depressive symptoms in adulthood - A 15-year follow-up study from Northern Finland Birth Cohorts.

BACKGROUND: Low optimism and high pessimism have predicted depressive symptoms in several studies, but the associations in the other direction, from depressive symptoms to future optimism and pessimism, have been unexplored. We examined bidirectional associations of optimism and pessimism with depressive symptoms in adulthood. METHODS: A population-based sample of 4011 Finnish adults (55 % women) was analyzed with a 15-year prospective follow-up period from age 31 to age 46. Optimism and pessimism were measured with the Life Orientation Test-Revised, and depressive symptoms were measured with the Symptom Checklist-25. Temporal associations were investigated with cross-lagged panel models. RESULTS: According to the model fit indices (RMSEA < 0.04, CFI ≥ 0.97) optimism and pessimism had bidirectional relationships with depressive symptoms: optimism predicted lower depressive symptoms (ß = -0.09, p < .001), and depressive symptoms predicted lower optimism (ß = -0.10, p < .001) in the follow-up. Also, pessimism predicted higher depressive symptoms (ß = 0.08, p < .001), and depressive symptoms predicted higher pessimism (ß = 0.09, p < .001) in the follow-up. In the participants with clinically high depressive symptoms at age 31, the predictive associations from optimism and pessimism to depressive symptoms remained, but associations in the other direction were attenuated. LIMITATIONS: The follow-up study included only two time points with a 15-year time gap, which does not consider the possible fluctuation in the study variables between the measured times. CONCLUSION: Dispositional optimism and pessimism may have bidirectional relationships with depressive symptoms in adulthood when the baseline depressive symptoms are below the clinical level.

Relations of optimism and purpose in life to immune markers in aging.

OBJECTIVE: Optimism and purpose in life are associated with improved health outcomes. More information is needed on biological mechanisms, including immunosenescence. We investigated if psychological well-being is associated with healthier immunosenescence-related measures including naïve and terminally differentiated CD4+ and CD8+ T cell percentages, CD4+:CD8+, and cytomegalovirus (CMV) IgG response. METHODS: Participants were adults over age 50 from the Health and Retirement Study. Optimism was measured using the Life Orientation Test Revised. Purpose in life was assessed using the subscale from the Ryff psychological well-being measure. We examined the cross-sectional associations of optimism and purpose in life with measures of T cell subsets using linear regression and with CMV IgG using ordered logit regression, controlling for potential confounding factors. RESULTS: The final analytic sample ranged from 7250 to 7870. After adjusting for sociodemographic factors, a 1-SD increment in optimism was associated with the percentage of naïve CD4+ T cells increasing by 0.6 (95%CI 0.2%, 1.0%). A 1-SD increment in purpose in life was associated with the percentage of naïve CD4+ T cells increasing by 0.9 (95%CI 0.5%, 1.3%) after adjusting for sociodemographic factors and the association was maintained after further adjustments for health conditions, depression, and health behaviors. For naïve CD8+ T cell percentages, CD4:CD8 ratios, and CMV IgG antibodies, associations were seen only in models that adjusted for age. No significant associations were seen in any models for the terminally differentiated CD4+ and CD8+ T cells. CONCLUSIONS: We found associations of optimism and purpose in life with naïve CD4+ T cell percentages.

HIV Treatment Optimism Moderates the Relationship between Sexual Risk Behavior and HIV Risk Perception among Urban HIV-negative Gay, Bisexual, and Other Men who have Sex With Men.

Using baseline data of the Engage Cohort Study, a Canadian study of sexually active gay, bisexual and other men who have sex with men (GBM), we evaluated the association between sexual behavior and risk perception among HIV-negative participants and whether HIV treatment optimism moderated this relationship. Participants were recruited by respondent-driven-sampling (RDS). We defined high-risk sexual behavior in the past six months as any condomless anal sex with a casual partner (i.e. not the participant's main partner) with either unknown HIV-status where neither used pre-exposure prophylaxis or with a partner living with HIV having detectable/unknown viral load. We assessed HIV treatment optimism-skepticism using a 12-item scale. RDS-II-weighted adjusted logistic regression models examined associations with risk perception measured by the question "How would you assess your current risk of getting HIV?" (response options were on a 6-point Likert-scale ranging from "very unlikely" to "very likely", dichotomized into "No Perceived Risk" (very unlikely/unlikely) and "Perceived Risk" (somewhat likely/likely/very likely/I think I already have HIV). Of 1961 participants, engagement in high-risk sexual behavior was reported by 155 (17.0%), 62 (12.4%), 128 (17.2%) of participants in Montréal, Toronto, and Vancouver, respectively. High-risk sexual behavior increased the odds of perceived HIV risk (pooled adjusted odds ratio = 2.9, 95%CI = 2.2-3.8). HIV treatment optimism-skepticism scores moderated the relationship: for GBM engaging in high-risk sexual behavior, higher HIV treatment optimism-skepticism scores increased perceived HIV risk. Promoting awareness around advances related to HIV prevention and treatment is important for appropriate risk assessment and for increased engagement in prevention interventions.

RESUMEN: Evaluamos la asociación entre el comportamiento sexual y la percepción de riesgo entre los participantes VIH negativos y si el optimismo sobre el tratamiento del VIH moderó esta asociación. Definimos comportamiento sexual de alto riesgo en los últimos seis meses como cualquier sexo anal sin condón con una pareja casual con un estado de VIH desconocido donde ninguno utilizó profilaxis previa a la exposición o con una pareja que vive con el VIH y que tiene una carga viral detectable/desconocida. Se evaluó el optimismo sobre el tratamiento del VIH mediante una escala de 12 ítems. Los modelos de regresión logística ajustados examinaron las asociaciones con la percepción del riesgo ("Riesgo no percibido" vs. "Riesgo percibido"). De 1961 participantes, 155 (17,0%), 62 (12,4%), 128 (17,2%) de los participantes en Montreal, Toronto y Vancouver, informaron comportamiento sexual de alto riesgo. El comportamiento sexual de alto riesgo se mostró asociado con riesgo percibido. El optimismo sobre el tratamiento modero la asociación. Promover la conciencia sobre los avances relacionados con la prevención y el tratamiento del VIH es importante para una evaluación adecuada de los riesgos y una mayor participación en las intervenciones de prevención.

The mediating effect of positive expectations in the relationship between social support and post-traumatic stress disorder symptoms among parents of children with acute lymphoblastic leukemia.

PURPOSE: Parents of children with cancer are exposed to risks of developing post-traumatic stress disorder (PTSD) symptoms, but few studies have explored PTSD symptoms of Chinese parents of children with acute lymphoblastic leukemia (ALL). Our study aimed to examine the association between social support and PTSD symptoms and to examine the mediating effect of positive expectations in this relationship among parents of children with ALL. METHODS: A cross-sectional study was conducted of consecutive parents of children with ALL in the Shengjing Hospital of China Medical University. A total of 177 parents eligible for this study completed questionnaires on PTSD symptoms, perceived social support, optimism and general self-efficacy anonymously. Asymptotic and resampling strategies were used to examine how positive expectations mediated the association between perceived social support and PTSD symptoms. RESULTS: Mean score of PTSD symptoms was 37.64 ± 14.44; 29.4% of the sample scored 44 and above, 19.8% scored 50 and above. After adjusting for covariates, perceived social support was negatively associated with the total score of PTSD symptoms (ß = -0.209, p < 0.01). Positive expectations were found to mediate the relationship between perceived social support and PTSD symptoms, especially for the symptoms of avoidance and hyperarousal. CONCLUSIONS: Optimism and general self-efficacy fully mediated the association between perceived social support and PTSD symptoms. Therefore, social support and positive expectations should be included in PTSD preventions and treatments targeting Chinese parents of children with ALL.

Are lateralized and bold fish optimistic or pessimistic?

Cognitive bias is defined as the influence of emotions on cognitive processes. The concept of the cognitive judgement bias has its origins in human psychology but has been applied to animals over the past 2 decades. In this study we were interested in determining if laterality and personality traits, which are known to influence learning style, might also be correlated with a cognitive bias in the three-spined sticklebacks (Gasterosteus aculeatus). We used the judgement bias test with the go/no-go procedure where fish were first trained to discriminate between a black and white card and, after reaching a minimum learning criterion, tested their response to an ambiguous card (grey). Optimistic subjects were expected to have a high expectation of reward associated with an ambiguous stimulus, whereas pessimistic subjects a high expectation of non-reward. We used an emergence and a mirror test to quantify boldness and laterality, respectively. We hypothesised that male, bolder and more strongly lateralized fish would be more optimistic than female, shy and less strongly lateralised fish. We found that males and more strongly lateralized fish were more optimistic than females and less strongly lateralized fish. In addition, bold males were more optimistic than shy males as we predicted, but females showed the opposite pattern. Finally, fish trained on the black colour card learned the training task faster than those trained on a white card. Our results indicate that both laterality and personality traits are linked to animals' internal states (pessimistic or optimistic outlooks) which likely has broad implications for understanding animal behaviour particularly in a welfare context.

Upper-Body Muscular Endurance and Its Association with Aerobic Capacity in University Students of Physical Culture, Sport, and Recreation / Fuerza resistencia de miembros superiores y su asociación con la capacidad aeróbica en universitarios de cultura física, deporte y recreación / Resistência Muscular do Corpo Superior e sua Associação com Capacidade Aeróbica em Estudantes Universitários de Cultura Física, Esporte e Recreação

Abstract Introduction: Upper-body muscular endurance (UBME) and aerobic capacity (AC) are essential components of physical fitness. Low levels of these components are related to cardiovascular disease. Purpose: To assess the association between UBME and AC levels in college students of physical culture. Methodology: Analytical cross-sectional study carried out in 192 students (169 men, 23 women; median age 20 years). Every participant of the study signed written consent. UMBE was the dependent variable assessed by the push-up test, and AC was the main independent variable assessed using the 20 m shuttle run test. To analyze differences by sex, and academic semester, Fischer exact, Student's T, and U Mann-Whitney tests were applied. Descriptive, as well as bivariate and multivariate analysis, were realized using logistic regression models. Results: 82.29 % of participants had healthy levels of UBME. Respecting the academic semester, students had a higher probability of having healthy levels of UBME as semesters increased (OR: 1.23, 95 % CI: 1.06 to 1.44, p = 0.007). Concerning AC, 58.33 % of participants registered healthy levels. After adjusting by sex, age, socioeconomic level, and academic semester, maximum oxygen consumption (VO2max), was associated with healthy levels of UBME (OR: 1.157, CI 95 %: 1.O71 - 1.249, p=<0.001). Conclusions: Students had a higher probability of presenting healthy levels of UBME as semesters of study increased, and those with a higheVO2max were more likely to have healthy levels of UBME.

Seeing the impossible: the impact of watching magic on positive emotions, optimism, and wellbeing.

Watching a magic trick is a unique experience in which seemingly impossible events appear possible but without any suspension of disbelief. Unfortunately, relatively little work has examined the psychological impact of this fascinating experience. In the current study, participants first completed a measure of the degree to which they disliked magic (Loathing of Legerdemain Scale: LOLS) and then watched a video that either contained a series of magic tricks (magic video) or carefully matched non-magic tricks (control video). Participants then rated the degree to which they experienced positive epistemic emotions (Epistemically Related Emotion Scale: ERES), their belief about impossible events being possible in the future (Modal Judgment Task: MJT), general optimism (State Optimism Measure: SOM) and subjective wellbeing (Satisfaction With Life Scale: SWLS). Compared to participants who watched the control video, those who saw the magic video reported more positive epistemic emotions on the ERES. There were no significant differences on the MJT, SOM and SWLS. Participants' LOLS scores were negatively correlated with the ERES, SOM and SWLS, suggesting that those who like magic are more likely to experience positive epistemic emotions, have higher levels of general optimism, and express greater satisfaction with their lives. These findings are discussed within the context of short-term and long-term exposure to magic, along with recommendations for future work.

Perceived stress, optimism-pessimism, psychological adjustment, and death distress of nurses during the COVID-19 pandemic.

OBJECTIVE: the aim of this study is to investigate the relationship between death distress, psychological adjustment, optimism, pessimism and perceived stress among nurses working during the COVID-19 pandemic. METHOD: this study was designed as cross-sectional/cohort. The population of the study involved 408 nurses from Northern Cyprus, which are registered as full members of the Nurse Council. The sample comprised 214 nurses, who volunteered to participate in the study. The study data was collected using a web-based online survey (Demographic form, the Coronavirus Stress Measure, The Optimism and Pessimism Questionnaire, The Brief Adjustment Scale-6, The Death Distress Scale). RESULTS: the results indicated that perceived stress significantly and negatively predicted optimism (ß = -0.21, p < 0.001) and pessimism (ß = 0.38, p < 0.001). Perceived stress had significant and positive predictive effects on psychological adjustment (ß = 0.31, p < 0.001) and death distress (ß = 0.17, p < 0.01). Further analysis results revealed that pessimism mediates the association of stress with psychological adjustment and death distress; however, optimism only mediates the effect of stress on psychological adjustment among nurses. CONCLUSION: a low level of pessimism is effective in strengthening nurses' psychological adjustment skills againt perceived stress and death distress. Nurses should consider behavioral strategies to help reduce the level of pessimism during periods such as pandemics. BACKGROUND: (1) High levels of perceived stress increased higher score of psychological adjustment. (2) Pessimism mediates the association of stress with adjustment and death distress. (3) Optimism only mediates the effect of stress on psychological adjustment among nurses.

Impact of COVID-19 pandemic on physician-scientist trainees to faculty one year into the pandemic.

PURPOSE: Physician-scientists play a crucial role in advancing biomedical sciences. Proportionally fewer physicians are actively engaged in scientific pursuits, attributed to attrition in the training and retention pipeline. This national study evaluated the ongoing and longer-term impact of the COVID-19 pandemic on stress levels, research productivity, and optimism for physician-scientists at all levels of training. METHODS: A multi-institutional cross-sectional survey of medical students, graduate students, and residents/fellows/junior faculty (RFJF) was conducted from April to August 2021 to assess the impact of COVID-19 on individual stress, productivity, and optimism. Multivariate regression analyses were performed to identify associated variables and unsupervised variable clustering techniques were employed to identify highly correlated responses. RESULTS: A total 677 respondents completed the survey, representing different stages of physician-scientist training. Respondents report high levels of stress (medical students: 85%, graduate students: 63%, RFJF: 85%) attributed to impaired productivity concerns, concern about health of family and friends, impact on personal health and impairment in training or career development. Many cited impaired productivity (medical students: 65% graduate students: 79%, RFJF: 78%) associated with pandemic impacts on training, labs closures and loss of facility/resource access, and social isolation. Optimism levels were low (medical students: 37%, graduate students: 38% and RFJF: 39%) with females less likely to be optimistic and more likely to report concerns of long-term effects of COVID-19. Optimism about the future was correlated with not worrying about the long-term effects of COVID-19. Since the COVID-19 pandemic, all respondents reported increased prioritization of time with family/friends (67%) and personal health (62%) over career (25%) and research (24%). CONCLUSIONS: This national survey highlights the significant and protracted impact of the COVID-19 pandemic on stress levels, productivity, and optimism among physician-scientists and trainees. These findings underscore the urgent need for tailored support, including mental health, academic, and career development assistance for this biomedical workforce.

Future optimism group based on the chronological stress view is less likely to be severe procrastinators.

Previous studies have shown that procrastinators tend to disregard the future. However, the "time view" of procrastinators, including their impressions of the future, has not been sufficiently examined. Therefore, we introduced new indices, "chronological stress view" and "chronological well-being view," which treat impressions of the past, present, and future (= time view) as time-series data via stress and well-being, respectively. The results showed that the group that believed that stress did not increase as they moved into the future had a lower percentage of severe procrastinators. No relationship was found between the chronological well-being view and procrastination. This result suggests that people who are relatively optimistic about the future based on the chronological stress view are less likely to be severe procrastinators. This may suggest the importance of having a hopeful prospect in the future to avoid procrastinating on actions that should yield greater rewards in the future.
