The relations between growth mindset, motivational beliefs, and career interest in math intensive fields in informal STEM youth programs.

Past research has shown that growth mindset and motivational beliefs have an important role in math and science career interest in adolescence. Drawing on situated expectancy-value theory (SEVT), this study extends these findings by investigating the role of parental motivational beliefs (e.g., expectancy beliefs, utility values) and parent growth mindset in math on adolescent career interest in math-intensive fields (e.g., mathematics, computer science, statistics, and engineering; MCSE) through adolescent motivational beliefs in math. Structural equation modeling was used to test the hypothesized model using data from 290 adolescents (201 girls, 69.3%; Mage = 15.20), who participate in informal STEM (science, technology, engineering, mathematics) youth programs, and their parents (162 parents, 87.7% female) in the United Kingdom and the United States. As hypothesized, adolescent expectancy beliefs, utility values, and growth mindset in math had a significant direct effect on MCSE career interest. Further, there was a significant indirect effect of parental expectancy beliefs in math on MCSE career interest through adolescents' expectancy beliefs. Similarly, there was a significant indirect effect from parental utility values in math to MCSE career interest through adolescents' utility values. The findings suggest that parents' math motivational beliefs play a critical role in adolescent math motivational beliefs and their career interest in math-intensive fields.

Children's and adolescents' evaluations of wealth-related STEM inequality.

The fields of science, technology, engineering, and mathematics (STEM) are rife with inequalities and under-representation that have their roots in childhood. While researchers have focused on gender and race/ethnicity as two key dimensions of inequality, less attention has been paid to wealth. To this end, and drawing from the Social Reasoning Development approach, we examined children's and adolescents' perceptions of STEM ability and access to opportunities as a function of wealth, as well as their desire to rectify such inequalities. Participants (n = 234: early childhood, n = 70, mean age = 6.33, SD = .79; middle childhood, n = 92, mean age = 8.90, SD = .83 and early adolescence, n = 62, mean age = 12.00; SD = 1.16) in the U.K. (64% White British) and U.S. (40% White/European American) read about two characters, one high-wealth and one low-wealth. In early childhood, participants reported that the high-wealth character would have greater STEM ability and were just as likely to invite either character to take part in a STEM opportunity. By middle childhood, participants were more likely to report equal STEM abilities for both characters and to seek to rectify inequalities by inviting the low-wealth character to take part in a STEM opportunity. However, older participants reported that peers would still prefer to invite the high-wealth character. These findings also varied by ethnic group status, with minority status participants rectifying inequalities at a younger age than majority status participants. Together these findings document that children are aware of STEM inequalities based on wealth and, with age, will increasingly seek to rectify these inequalities.

Developmental Trajectories of Adolescents' Math Motivation: The Role of Mindset and Perceptions of Informal STEM Learning Site Inclusivity.

Motivation is a key factor in engagement, achievement, and career choices in science, technology, engineering, and mathematics (STEM). While existing research has focused on student motivation toward math in formal school programs, new work is needed that focuses on motivation for those involved in informal STEM programs. Specifically, the role of math mindset and perceived inclusivity of informal STEM sites (to those of varying gender and ethnic backgrounds) on longitudinal trajectories of adolescents' math motivation has not been explored. This study investigates longitudinal changes in math expectancy, interest, and utility values and the effects of math fixed mindset, math growth mindset, and perceptions of the inclusivity of informal STEM learning sites on these changes for adolescents participating in STEM programs at these informal sites in the United Kingdom and the United States (n = 249, MT1age = 15.2, SD = 1.59). Three latent growth curve models were tested. The data suggest that math expectancy, interest, and utility values declined over three years. Growth mindset positively predicted changes in utility, while fixed mindset negatively predicted changes in utility. Inclusivity positively influenced the initial levels of utility. Girls reported lower initial expectancy than boys. Age influenced both the initial levels and rate of change for expectancy. Older adolescents had lower levels of expectancy compared to their younger counterparts; however, they had a less steep decline in expectancy over three years. These findings suggest that designing inclusive learning environments and promoting growth mindset may encourage math motivation.

Reciprocal Associations Between Science Efficacy, STEM Identity and Scientist Career Interest Among Adolescent Girls within the Context of Informal Science Learning.

Limited research has explored the longitudinal pathway to youth career interests via identity and efficacy together. This study examined the longitudinal associations between science efficacy, STEM (science, technology, engineering and math) identity, and scientist career interest among girls who are historically considered as an underrepresented group among scientists. The sample included 308 girls (M age = 15.22, SD age = 1.66; 42.8% White) from six STEM youth programs, each at a different informal science learning site within the U.K. and the U.S. Longitudinal structural equation modelling demonstrated that science efficacy consistently predicted STEM identity and scientist career interest, and similarly, STEM identity consistently predicted science efficacy over a two-year period. Scientist career interest at 12 months predicted science efficacy at 24 months. The coefficients of efficacy predicting STEM identity and scientist career interest were significantly larger compared to STEM identity and scientist career interest in predicting science efficacy from 12 months to 24 months. Further mediation analysis supported a significant pathway from STEM identity at 3 months to scientist career interest at 24 months via 12-month science efficacy. The findings highlight that science efficacy and STEM identity for girls relate to their scientist career interest and these longitudinal associations are reciprocal. This study suggests that science efficacy and STEM identity mutually influence each other, and enhancing science efficacy and STEM identity is key to promoting adolescents' interest in being a scientist.

Adolescents' Expectations for Types of Victim Retaliation Following Direct Bullying.

Little is known about adolescents' expectations around how victims of bullying might retaliate following victimization. These expectations are important as they may inform adolescent's own behaviors, particularly intervention behaviors, in regard to bullying and potential retaliation. This study investigated adolescents' retaliation expectations and expected bystander reactions to retaliation following physical and social bullying. Participants included 6th grade (N = 450, Mage = 11.73 years, SD = 0.84) and 9th grade (N = 446, Mage = 14.82 years) adolescents (50.2% female, 63.3% European American, 22.9% African American, 3.9% Latino/a, 7% Multiracial, 2.9% Other) from middle-to-low-income U.S. public schools. Participants responded to open-ended prompts about victim responses to bullying, rating retaliation acceptability, and likelihood of engaging in bystander behaviors. ANOVAs were conducted to examine differences in retaliation expectation by type of aggression. Further, linear regressions were used to explore what factors were related to participants' expectations regarding bystander intervention. Participants expected victims to retaliate by causing harm and expected the type of retaliation to match the type of bullying. Younger participants were more specific and males were more likely to expect physical harm than females. Finally, acceptability of retaliation predicted bystander interventions. Adolescents expect aggressive retaliation suggesting that intervention might focus on teaching them ways to respond when they are bullied or observe bullying.

The effect of parental food neophobia on children's fruit and vegetable consumption: A serial mediation model.

Children in the United States do not consume the recommended amounts of healthful foods such as fruits and vegetables. In order to investigate factors associated with children's fruit and vegetable consumption, we used serial mediation models based on a theoretical model proposed by Kaar et al., [Food Quality & Preference, 50, 57-64 (2016)] to assess the indirect effect of parental food neophobia (X) on children's consumption (Y) of fruits and vegetables through two serial mediators, variety of fruits and vegetables offered at home (variety offered; M1) and child food neophobia (M2). This was accomplished with a sample of 148 children between 5 and 10 years of age (Mage = 7.71 years, 44.7% female). We measured parental and child food neophobia and parents' reports of the frequency with which they regularly offered a variety of fruits and vegetables. In addition, children completed a laboratory task in which they were presented with four different fruits and vegetables and were asked to try the foods. Analyses revealed a significant indirect effect of parents' food neophobia on consumption of fruits and vegetables through variety offered (M1) and child food neophobia (M2). There was also a significant serial indirect effect of parent food neophobia on consumption through variety offered and child food neophobia. The results provide further evidence to support the contention that parent and child neophobia and the feeding environment exert a strong influence on children's fruit and vegetable consumption.

Bariatric venous thromboembolism prophylaxis: an update on the literature.

Introduction: Rates of obesity have been increasing worldwide and with the current situation obesity now represents an epidemic. Bariatric surgery is one the most effective ways to help reduce weight and sustain weight loss. Venous thromboembolism is a major cause of morbidity and mortality among bariatric surgery patients with no clearly established guidelines on prophylaxis. Areas covered: In this review the authors summarize clinical studies evaluating unfractionated heparin (UFH) and low molecular weight heparins (LMWH) in bariatric surgery patients. The authors present studies that assessed venous thromboembolic (VTE)-related risk stratification but also various dosing regimens of heparin products in this population of patients. Moreover, the authors will also present the feasibility of using direct oral anticoagulants (DOACs) for venous thromboembolism (VTE) prevention along with providing a summary of few current guidelines for VTE prevention in bariatric surgery patients. Expert opinion: Based on the data presented in this review, the authors conclude that LMWHs may be better options than UFH for VTE prophylaxis in bariatric surgery patients. We also conclude that risk stratifying bariatric patients may be a better approach when deciding on the best thromboprophylaxis modality, dose and duration.

Severe Hypocalcemia and Hypomagnesemia with Denosumab in Advanced Chronic Kidney Disease: Case Report and Literature Review.

BACKGROUND: Denosumab has become the preferred agent over zolendronic acid to help prevent skeletal-related events in patients with metastatic bone disease and multiple myeloma because it is approved for use in those with kidney dysfunction. However, denosumab has been linked to cases of hypocalcemia, particularly in those with advanced kidney disease. CASE PRESENTATION: We present the case of a patient with metastatic prostate cancer and chronic kidney disease due to obstructive nephropathy who developed severe hypocalcemia and hypomagnesemia after denosumab injection, which required intensive care unit admission, aggressive calcium supplementation, and hemodialysis assistance. We reviewed the evidence behind the safety profile of denosumab in chronic kidney disease, and we also looked at additional factors that may precipitate severe hypocalcemia with denosumab in advanced kidney disease. CONCLUSION: We believe that denosumab should be avoided in advanced chronic kidney disease due to the potential life-threatening, severe hypocalcemia that has been observed.
