Background/Objectives: Maternal mental health concerns are a leading cause of maternal morbidity and mortality, disproportionately impacting Black mothers in the United States. Structural racism and social determinants of health contribute to increased risks of perinatal mental health issues, limited access to formal services, and adverse health outcomes for Black mothers. While formal mental health services are underutilized, Black mothers employ a variety of culturally relevant and context-specific strategies to support their mental health. This study seeks to understand the barriers, preferences, and experiences that guide their decision-making and inform culturally responsive care. Methods: This qualitative study employed thematic analysis of in-depth interviews conducted with 12 Black mothers aged 20–39 residing in a midwestern metropolitan area. The research explored individual experiences, preferences for support, and perspectives on healthcare to identify pathways for advancing mental health equity. Results: Three major themes emerged: (1) Expanding conceptions of mental health support beyond traditional services, emphasizing preferences for culturally congruent, convenient, and stress-decreasing interventions; (2) The salience of past experiences and identities in shaping support preferences and decisions; (3) What healthcare professionals can do, the knowledge and skills healthcare professionals can gain, and the actions that they can to become more helpful to Black mothers. The importance of healthcare professionals embodying nonjudgmental, patient, and caring attributes, as well as strengths-based, culturally responsive approaches in care. Conclusions: Advancing mental health equity for Black mothers requires increased awareness of existing disparities, barriers to care, and the strengths embedded within their communities. This research provides actionable insights for healthcare providers, policy makers, and researchers to identify, assess, and respond to the unique needs of Black mothers through culturally responsive and participatory approaches. Findings have implications for intervention design, theory development, and policy reform to improve mental health outcomes. Full article

Objectives: Colorectal cancer (CRC) is the second-deadliest cancer globally, with an estimated 52,900 additional deaths expected in the United States by 2025. Early detection through colonoscopy significantly reduces CRC mortality by enabling the removal of pre-cancerous polyps. However, manual visual inspection of colonoscopy images is time-consuming, tedious, and prone to human error. This study aims to develop an automated and reliable polyp segmentation and classification method to improve CRC screening. Methods: We propose a novel deep learning architecture called µ-Net for accurate polyp segmentation in colonoscopy images. The model was trained and evaluated using the Kvasir-SEG dataset. To ensure transparency and reliability, we incorporated Explainable AI (XAI) techniques, including saliency maps and Grad-CAM, to highlight regions of interest and interpret the model’s decision-making process. Results: The µ-Net model achieved a Dice coefficient of 94.02%, outperforming other available segmentation models in accuracy, indicating its strong potential for clinical deployment. Integrating XAI provided meaningful visual explanations, enhancing trust in model predictions. Conclusions: The proposed µ-Net framework significantly improves the Precision and efficiency of automated polyp screening. Its ability to segment, classify, and interpret colonoscopy images enables early detection and supports clinical decision-making. This comprehensive approach offers a valuable tool for CRC prevention, ultimately contributing to better patient outcomes. Full article

This research examines how reminders of mortality influence prosocial behavior through the lens of terror management theory. We propose that these effects depend on individuals’ global–local identity—the degree to which they identify with the broader world versus a local community. In two experimental studies, participants were exposed to mortality salience manipulations and then reported their intentions to engage in prosocial behaviors. The results consistently showed that mortality salience increased prosocial intentions for individuals with a global identity but not for those with a local identity. This interaction was explained by differences in perceived social connectedness. Together, these findings highlight the role of global–local identity in shaping prosocial responses to mortality reminders, offering theoretical insights into terror management processes and practical implications for fostering prosociality in diverse social contexts.

The terror management health model (TMHM) offers a framework to investigate how concerns about mortality can motivate health-related behaviors through actions that bolster self-esteem. This framework may be especially useful for examining how a family history of breast cancer influences preventative breast health behaviors. Women with no family history, a family history where a family member survived breast cancer, and those who lost a family member to the disease were recruited to participate in one of two preregistered online studies. Participants completed measures of perceived susceptibility, associations of breast cancer with death, breast health esteem, and behavioral breast health intentions. In both studies, the effect of family history on behavioral intentions was serially mediated by susceptibility perceptions, breast cancer–death association, and feelings of esteem related to breast health behaviors. There were no effects of priming mortality. Taken together, the results suggest that both susceptibility perceptions and death associations are critical for encouraging breast health behaviors among women with family history, and this works through a mechanism relevant to self-esteem. Interventions may be more effective when they emphasize the esteem value of breast health behaviors for individuals at increased risk. Full article

A necessary condition for the success of the 7 October 2023 Hamas deadly incursion into Israel was the absence of the Israel Defense Forces (IDF) from that region. The IDF was involved in helping the settlers in their conflicts with Palestinians on the West Bank, many miles from the Gaza border. Absent the settlers, it is likely that either the Hamas attack might not have occurred or would have been blunted at the outset, yielding a much more measured Israeli response. Hence it is imperative that we understand the origins of the settler movement. It is to be found in Biblical injunctions that were to be amplified considerably by the outcomes of the extraordinarily successful Six-Day war of 1967 and its sequel the Yom Kippur war of 1973. In the third chapter of the Book of Genesis, that is, of the entire Hebrew Bible, God commands Abraham to leave his current domicile and travel to Canaan where a great nation would be formed. Effectively, this is the religious foundation of the connection between the people of Israel and the land of Israel, then called Canaan. The contrast between the outcomes of 1967 and 1973 was striking. Instead of a lopsided victory in the earlier war, the human losses in 1973 were surprising, even terrifying. This intense ephemeral gain combined with a world view defense engendered by mortality salience established the basis for later religious Zionist extremism. The vastly increased number of casualties in 1973 set the stage for the victory of Likud, much more amenable to West Bank settlements than the ousted Labor government had been. Religious Zionists leaped at this opportunity, justifying this activity by referring to God’s commandment to settle the entire land of Israel in the West Bank territories using their Biblical Hebrew names: Yehuda (Judea) and Shomron (Samaria), whatever the cost in violent Palestinian land dispossession.

Fairness-related decision-making often involves a conflict between egoistic and prosocial motives. Previous research based on Terror Management Theory (TMT) indicates that mortality salience can promote both selfish and prosocial behaviors, leaving its effect on fairness-related decision-making uncertain. This study integrates TMT with the strength model of self-control to investigate the effects of mortality salience on fairness-related decision-making and to examine the moderating role of dispositional self-control. Participants were primed with either mortality salience or negative affect and then asked to make a series of binary choices (equal allocation vs. unequal allocation favoring themselves) to distribute monetary resources. In both studies, mortality salience heightened selfish tendencies, leading to less equitable monetary allocation. Study 2 further revealed that this effect occurred among participants with low, but not high, self-control. These findings indicate that mortality salience promotes selfishness and inequitable monetary allocation, but that self-control can buffer these effects. Full article

This study investigates the role of anthropomorphic design in alleviating consumer anxiety induced by mortality salience and delves into the underlying emotional and non-emotional mechanisms. Through a series of meticulously designed experiments, we confirm that anthropomorphic design significantly enhances positive emotional responses in consumers, reduces negative emotions, and thereby increases their preference and willingness to purchase products. Even after the diminution of emotional reactions, anthropomorphic design continues to sustain consumer preference by enhancing psychological intimacy. These findings reveal the crucial role of anthropomorphic design as an effective emotional regulation strategy in consumer purchasing behavior, enriching the application of terror management theory and emotion regulation theory in consumer behavior research. Furthermore, our study provides valuable practical guidance for product design and marketing strategies, especially for consumer groups frequently facing high-pressure situations. Products with anthropomorphic designs may be more appealing to these consumers, helping to mitigate their death anxiety and enhance psychological well-being. Full article

Background and aims: The prominence of death during the COVID-19 pandemic was heightened by the potential of personally knowing someone who lost their life to the virus. The terror management theory (TMT) suggests that the salient presence of death has a pronounced effect on behavior and may result in the ossification of beliefs and actions aligned with one’s worldview (i.e., the mortality salience hypothesis). In this study, we evaluated how death exposure early in the COVID-19 pandemic could enact the process of firming up held beliefs and attitudes related to health and safety. Specifically, we tested the hypothesis that exposure to a personal loss during the pandemic would strengthen participants’ baseline attitudes and behaviors regarding COVID-19 safety guidelines. Method: Data were analyzed from a prospective, regional survey administered at two time points during the pandemic, June–July 2020 and May 2021, in five United States northeastern states. Baseline and follow-up surveys were administered approximately 12 months apart, with adherence to public guidance and death exposure measured at both timepoints and other safety measures at follow-up only. Findings: Our results indicated that there were significant main effects of death exposure on guideline adherence and support for COVID-related public policy. Contrary to the mortality salience hypothesis, death exposures after baseline were related to higher medical mistrust at follow-up for those high in adherence at baseline, rather than those with low adherence. Conclusion: Our results offer some conflicting evidence to the mortality salience hypothesis. Rather than entrench people in their worldviews, death in the context of the COVID-19 pandemic appeared to sway people away from their initial stances. This finding has important implications for TMT literature and for the COVID-19 pandemic response. Full article

The Terror Management Theory (TMT) offered a great deal of generative hypotheses that have been tested in a plethora of studies. However, there is a still substantive lack of clarity about the interpretation of TMT-driven effects and their underlying neurological mechanisms. Here, we aimed to expand upon previous research by introducing two novel methodological manipulations aimed to enhance the effects of mortality salience (MS). We presented participants with the idea of the participants’ romantic partner’s death as well as increased the perceived threat of somatosensory stimuli. Linear mixed modelling disclosed the greater effects of MS directed at one’s romantic partner on pain perception (as opposed to the participant’s own mortality). The theta event-related oscillatory activity measured at the vertex of the scalp was significantly lower compared to the control condition. We suggest that MS aimed at one’s romantic partner can result in increased effects on perceptual experience; however, the underlying neural activities are not reflected by a classical measure of cortical arousal.

The United Nations has established 17 Sustainable Development Goals (SDGs) as a global initiative to achieve a more sustainable future. Within these goals, SDG16 emphasizes the significance of sustainable public sector management, which profoundly influences the accomplishment of other SDGs. Enhancing public service motivation is a critical element in advancing sustainable public sector management. This study explores the potential of mortality salience as an intervention to bolster public service motivation, aiming to provide valuable insights for SDG16. Specifically, the study investigates the varied effects of mortality salience on public service motivation using a survey experiment and employs machine learning techniques. The findings reveal a significant positive impact of mortality salience on public service motivation. Furthermore, this study highlights that this impact is more prominent in organizations characterized by high levels of servant leadership and extrinsic rewards, as well as low levels of organization-based self-esteem. These findings have practical implications for fostering sustainable public sector management in the post-COVID-19 pandemic era. Full article

Lung and colon cancers are among the leading causes of human mortality and morbidity. Early diagnostic work up of these diseases include radiography, ultrasound, magnetic resonance imaging, and computed tomography. Certain blood tumor markers for carcinoma lung and colon also aid in the diagnosis. Despite the lab and diagnostic imaging, histopathology remains the gold standard, which provides cell-level images of tissue under examination. To read these images, a histopathologist spends a large amount of time. Furthermore, using conventional diagnostic methods involve high-end equipment as well. This leads to limited number of patients getting final diagnosis and early treatment. In addition, there are chances of inter-observer errors. In recent years, deep learning has shown promising results in the medical field. This has helped in early diagnosis and treatment according to severity of disease. With the help of EffcientNetV2 models that have been cross-validated and tested fivefold, we propose an automated method for detecting lung (lung adenocarcinoma, lung benign, and lung squamous cell carcinoma) and colon (colon adenocarcinoma and colon benign) cancer subtypes from LC25000 histopathology images. A state-of-the-art deep learning architecture based on the principles of compound scaling and progressive learning, EffcientNetV2 large, medium, and small models. An accuracy of 99.97%, AUC of 99.99%, F1-score of 99.97%, balanced accuracy of 99.97%, and Matthew’s correlation coefficient of 99.96% were obtained on the test set using the EffcientNetV2-L model for the 5-class classification of lung and colon cancers, outperforming the existing methods. Using gradCAM, we created visual saliency maps to precisely locate the vital regions in the histopathology images from the test set where the models put more attention during cancer subtype predictions. This visual saliency maps may potentially assist pathologists to design better treatment strategies. Therefore, it is possible to use the proposed pipeline in clinical settings for fully automated lung and colon cancer detection from histopathology images with explainability. Full article

As suicides incurred by the COVID-19 outbreak keep happening in many countries, researchers have raised concerns that the ongoing pandemic may lead to “a wave of suicides” in society. Suicidal ideation (SI) is a critical factor in conducting suicide intervention and also an important indicator for measuring people’s mental health. Therefore, it is vital to identify the influencing factors of suicidal ideation and its psychological mechanism during the outbreak. Based on the terror management theory, in the present study we conducted a social media big data analysis to explore the joint effects of mortality salience (MS), negative emotions (NE), and cultural values on suicidal ideation in 337 regions on the Chinese mainland. The findings showed that (1) mortality salience was a positive predictor of suicidal ideation, with negative emotions acting as a mediator; (2) individualism was a positive moderator in the first half-path of the mediation model; (3) collectivism was a negative moderator in the first half-path of the mediation model. Our findings not only expand the application of the terror management theory in suicide intervention but provide some insights into post-pandemic mental healthcare. Timely efforts are needed to provide psychological interventions and counseling on outbreak-caused negative emotions in society. Compared with people living in collectivism-prevailing regions, those living in individualism-prevailing regions may be more vulnerable to mortality salience and negative emotions and need more social attention.

During the pandemic, the mortality salience of COVID-19 has affected everyone. The public is extremely sensitive to food safety, especially cold chain food and imported food. This research is based on the terror management theory, protective motivation theory, and self-construal theory. It proposes an integrated dual-path framework to explore the different mechanisms that mortality salience has on food safety behavior. The result of three experiments verified our conjectures. First, mortality salience positively affects individuals’ food safety behavior. More importantly, we found the dual-path mechanism that underlies the effect, that is, the mediating of self-protective motivation and prosocial motivation. In addition, different self-construals make the confirmed effect clear. These findings provide implications for the government to protect public food safety and health. Full article

Disparities in colorectal cancer (CRC) mortality among White, Black, and American Indian/Alaska Native (AIAN) men are attributable to differences in early detection screening. Determining how masculinity barriers influence CRC screening completion is critical for cancer prevention and control. To determine whether masculinity barriers to medical care are associated with lower rates of ever completing CRC screening, a survey-based study was employed from December 2020–January 2021 among 435 White, Black, and AIAN men (aged 45–75) who resided in the US. Logistic regression models were fit to four Masculinity Barriers to Medical Care subscales predicting ever completing CRC screening. For all men, being strong was associated with 54% decreased odds of CRC screening completion (OR 0.46, 95% CI 0.23 to 0.94); each unit increase in negative attitudes toward medical professionals and exams decreased the odds of ever completing CRC screening by 57% (OR 0.43, 95% CI 0.21 to 0.86). Black men who scored higher on negativity toward medical professionals and exams had decreased odds of ever screening. Consideration of masculinity in future population-based and intervention research is critical for increasing men’s participation in CRC screening, with more salience for Black men. Full article

Studies have yielded inconclusive findings regarding the relationship between disaster experience and materialism. Whereas some have found a positive relationship, others have reported a negative relationship. To clarify the mechanisms underlying these mixed findings, we proposed and examined two mechanisms, namely mortality salience and gratitude. A total of 214 participants (M_age = 42.05 years, SD = 16.49 years) were randomly assigned into either an experimental condition to experience a disaster or a control condition. Participants in the experimental condition reported a lower level of materialism than the scores of their counterparts in the control condition. Such effects were mediated by both mortality salience and gratitude. Participants in the experimental condition reported higher levels of both mortality salience and gratitude simultaneously. Mortality salience strengthened materialism, but gratitude weakened materialism. These findings highlighted the duel-existing mechanisms underlying the relationship between disaster experience and materialism. Full article
