Satisfaction with one's academic major is critical to a university student's development. This study explores the interrelationships among thinking styles, grit, and academic major satisfaction in both deaf or hard-of-hearing (DHH) and hearing students, employing independent samples t-tests to compare the two groups, Pearson's correlation analysis to explore relationships among the variables, and mediation analysis to understand the mediating effect of grit on the relationship between thinking styles and academic major satisfaction. The results indicated significantly higher levels of grit and consistency of interest in DHH students than hearing students, with no significant differences in perseverance of effort. A strong correlation was found between thinking styles and both grit and academic major satisfaction, particularly in DHH students. Mediation analysis revealed that grit significantly mediated the relationship between thinking styles and academic major satisfaction, underscoring its role in enhancing students' academic experience. These findings contribute to the limited literature on DHH students' psychological attributes and the complex interplay of psychological constructs in academic major satisfaction, offering valuable insights for tailored educational strategies.

Science education reform has been underway for almost a century with the general aim to engage students and train scientists needed to find solutions to global challenges, and also ensure a general public well disposed towards science. In an effort to aid science reform, more recently, colleges and universities have been augmenting their academic workforce by embedding education-focused science faculty into science departments. However, little research has investigated how this approach, and the identity of these faculty, may be changing over time. Here we investigate how conceptualizations of professional identities of these faculty across the United States have changed over the last two decades. We found three professional identities amongst these faculty: Science Faculty with Education Specialties (SFES), Discipline-Based Education Researchers (DBER), and faculty who identify as both SFES and DBER. Evidence indicates this is a maturing field within higher-education science departments, with more direct hiring and training pathways, but with potentially diminishing agency. Finally, data reveal resilience and perseverance despite negative biases from peers and college administrators, especially at PhD-granting institutions.

INTRODUCTION
In medical education, the clerkship phase is a demanding period during which medical students learn to navigate the responsibilities of medical school and clinical medicine. Grit, a personal quality regarded as a non-cognitive trait, refers to perseverance and passion; specifically, it represents the ability to endure hardship and work industriously toward a goal. Most studies analysed grit as a single concept and few studies have investigated the effect of grit on the well-being of medical students through the whole-specialty training (i.e. surgical and non-surgical specialty rotations) required in clinical clerkships. Therefore, this study investigated whether associations exist between medical students' grit, measured by the two subconstructs of perseverance and passion, and their well-being during clerkships in surgical and non-surgical specialty units.
METHODS
This one-year prospective web-based questionnaire study enrolled fifth-year medical students at a tertiary medical centre in central Taiwan between September 2017 and July 2018 in their first-year clerkship. The students' sex, age, and grit were measured at the start of their clerkship. Routine surveys were conducted over one year to assess burnout and compassion satisfaction for students' well-being, and the training specialty characteristics of the surgical and non-surgical specialty departments were recorded. This study included 92 medical students and 1,055 survey responses from individual specialty rotations. Descriptive, univariate and multivariate analyses were performed.
RESULTS
Our results revealed that medical students' perseverance, as part of grit, was related to lower burnout and higher compassion satisfaction during clerkships, but not the subconstruct of passion. Moreover, the positive trait of perseverance measured in our study had greater explanatory power for compassion satisfaction than for burnout. Furthermore, the results revealed that older medical students suffered from less burnout than their younger counterparts, and that male medical students expressed higher compassion satisfaction than their female counterparts.
DISCUSSION
Perseverance, as a subconstruct of grit, is a positive personal quality for medical students' clerkships, and methods driving the cultivation of perseverance in medical education should be considered. In addition, even though positive traits such as perseverance equipped medical students for compassion satisfaction, additional factors attributed to medical students' burnout must be identified.

Inter-species comparisons are key to deriving an understanding of the behavioral and neural correlates of human cognition from animal models. We perform a detailed comparison of the strategies of female macaque monkeys to male and female humans on a variant of the Wisconsin Card Sort Test (WCST), a widely studied and applied task that provides a multi-attribute measure of cognitive function and depends on the frontal lobe. WCST performance requires the inference of a rule change given ambiguous feedback. We found that well-trained monkeys infer new rules three times more slowly than minimally instructed humans. Input-dependent Hidden Markov Model-Generalized Linear Models were fit to their choices, revealing hidden states akin to feature-based attention in both species. Decision processes resembled a Win-Stay Lose-Shift strategy with inter-species similarities as well as key differences. Monkeys and humans both test multiple rule hypotheses over a series of rule-search trials and perform inference-like computations to exclude candidate choice options. We quantitatively show that perseveration, random exploration and poor sensitivity to negative feedback account for the slower task-switching performance in monkeys. Advances in training and recording from animal models support the study of increasingly complex behaviors in non-humans. Before interpreting their neural computations as human-like, we must first ascertain whether their computational algorithms are human-like. We compared rapid rule-learning strategies of macaque monkeys and humans on a Wisconsin Card Sorting Test variant and found that monkeys are 3-4 times slower than humans at learning new rules. Model fits to choice behavior revealed that both species use qualitatively similar exploration strategies with different decision criteria. These differences produced distinct errors in monkeys that are similar to those observed in humans with prefrontal deficits. Our results generate detailed neural hypotheses and highlight the need for systematic inter-species behavioral and neural comparisons.

Review
The reuniens (Re) nucleus is located in the ventral midline thalamus. It has fostered increasing interest, not only for its participation in a variety of cognitive functions (e.g., spatial working memory, systemic consolidation, reconsolidation, extinction of fear or generalization), but also for its neuroanatomical positioning as a bidirectional relay between the prefrontal cortex (PFC) and the hippocampus (HIP). In this review we compile and discuss recent studies having tackled a possible implication of the Re nucleus in behavioral flexibility, a major PFC-dependent executive function controlling goal-directed behaviors. Experiments considered explored a possible role for the Re nucleus in perseveration, reversal learning, fear extinction, and set-shifting. They point to a contribution of this nucleus to behavioral flexibility, mainly by its connections with the PFC, but possibly also by those with the hippocampus, and even with the amygdala, at least for fear-related behavior. As such, the Re nucleus could be a crucial crossroad supporting a PFC-orchestrated ability to cope with new, potentially unpredictable environmental contingencies, and thus behavioral flexibility and adaption.

Review
Myocardial ischemia-reperfusion injury (MIRI) is fatal to patients, leading to cardiomyocyte death and myocardial remodeling. Reactive oxygen species (ROS) and oxidative stress play important roles in MIRI. There is a complex crosstalk between ROS and regulatory cell deaths (RCD) in cardiomyocytes, such as apoptosis, pyroptosis, autophagy, and ferroptosis. ROS is a double-edged sword. A reasonable level of ROS maintains the normal physiological activity of myocardial cells. However, during myocardial ischemia-reperfusion, excessive ROS generation accelerates myocardial damage through a variety of biological pathways. ROS regulates cardiomyocyte RCD through various molecular mechanisms. Targeting the removal of excess ROS has been considered an effective way to reverse myocardial damage. Many studies have applied antioxidant drugs or new advanced materials to reduce ROS levels to alleviate MIRI. Although the road from laboratory to clinic has been difficult, many scholars still persevere. This article reviews the molecular mechanisms of ROS inhibition to regulate cardiomyocyte RCD, with a view to providing new insights into prevention and treatment strategies for MIRI.

The photovoice literature has focused mainly on research collaborations between researchers in academia and community partners. There is limited evidence of undergraduate students facilitating photovoice research projects with underserved Black, Indigenous, and persons of color (BIPOC). Students' participation in photovoice research increases their understanding of local issues and can empower them to engage with local communities to create change. This qualitative study explored students' experiences facilitating photovoice research with BIPOC older adults and frontline healthcare workers. In this study, we trained college students in photovoice methodological skills by introducing photovoice as a participatory qualitative methodology, explained ethics issues and the informed consent process, and clarified the steps and requirements for the photovoice project. Students were paired with BIPOC older adults and frontline healthcare workers. They facilitated the photovoice research project in four stages. Throughout the study, students critically reflected and wrote about the various aspects of their experience facilitating the photovoice research activities based on weekly structured reflection questions. In their weekly journal, student facilitators commented on how both older and younger BIPOC participants were friendly and kind, flexible with the research activity scheduling, inspiring with their stories, and selfless. Students' reflections indicated that their participants experienced greater emotional and psychological burdens during the COVID-19 pandemic, exacerbated by the long-standing epidemic of systemic racism. Student facilitators overwhelmingly recognized participants' resilience and perseverance despite these life challenges. Our findings highlight the importance of photovoice in developing and strengthening college students' qualitative research skills and stimulating critical thinking and creativity, a sense of critical consciousness about social issues and society, and a sense of empowerment. Our results will be relevant to hospital/long-term care managers, policymakers, and researchers.

Review
BACKGROUND
Agentive steadfastness was identified as a potential trait marker with which to anticipate prognostically that a patient will persevere steadfastly and take congruent action in facing the demands of living. Taken as an enduring expression of personality, this study investigated agentive steadfastness among adult social media respondents (n = 511) in relation to temperament and character as captured in Cloninger's psychobiological model of personality.
METHODS
Participants recruited though snowball sampling on social media platforms, applied the 27-item Agentive Steadfastness Index (ASI) and the 240-item Temperament and Character Inventory (TCI-R-240).
RESULTS
Agentive steadfastness was statistically predicted by the Self-directedness (β = 0.634), Self-transcendence (β = 0.119), Harm Avoidance (β = -0.142) and the Reward Dependence (β = 0.071) scales, accounting for 63.3 % of the variance in one stepwise regression model. In another stepwise model for the TCI-R-240 subscales, the Purposeful (β = 0.359), Anticipatory Worry (β = -0.353), and the Responsibility (β = 0.259) subscales accounted for respectively 56.8 %, 11.2 % and 2.8 % of the variance in ASI scores.
LIMITATIONS
Results are limited to adult social media respondents who were willing to participate.
CONCLUSIONS
Agentive steadfastness may serve as a trait marker of well-being and the good prognostic associations that have been established for high self-directedness, low harm avoidance, as well as resilience, and character strengths. It may be assessed clinically to anticipate prognostically the extent to which a patient will persevere steadfastly and take congruent action in facing the demands of living and adversity.

Nanocrystals (NCs) exposed with high-index facets usually show enhanced electrocatalytic performances. However, it is a great challenge to persevere with high-index facets against their high surface energy during the synthesis. Herein, we successfully synthesize concave hexoctahedral (c-HOH) Pd NCs exposed with 48 high-index {741} facets using a facile one-pot wet-chemical protocol. Control experiments illustrate that l-ascorbic acid plays a critical role in the formation of the c-HOH morphology, acting as both reducing and capping agents. Moreover, we can extend the synthesis for fabricating c-HOH Pd@Pt core-shell NCs by simply introducing a Pt precursor into the reaction solution, attaining remarkably boosted electrocatalysis for methanol electrooxidation reaction (MOR). Integrating the merits of {741} facets, concave structure, and ligand and strain effect of the core-shell structure, c-HOH Pd@Pt core-shell NCs showed an excellent MOR mass activity of 1.18 A mg or 3.60 A mg, which is 3.80 or 11.61 times higher than that of commercial Pt/C, respectively.
