Background: School meal programs are not only government initiatives but also community-driven efforts. Aiming to combat food insecurity among school-aged children effectively, these programs are executed in conjunction with food bank initiatives. Various community groups play a crucial role in the success of both food security initiatives. There is a need to improve community engagement to successfully link school meal programs with food banks to build program synergy, combating food insecurity through a two-sided approach. Aim: This study aims to examine (...) community engagement in school meals program by analyzing its purposeful focus on creating jobs and income-generating opportunities for different community groups, i.e., youths, women, and others. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: Findings showed that the school meals program’s purposeful focus on creating jobs and income-generating opportunities for women in the community was positively associated with community engagement, thereby supporting the linkage between the programs and food banks. In contrast, providing jobs and income-generating opportunities for youths and other community groups had an ambiguous association with community engagement in school meal programs. Conclusions: Findings underscore the importance of creating jobs and income-generating opportunities for women to improve community engagement in school meal programs. Formulating strategies that empower woman’s entrepreneurship may foster their involvement and engagement in school meal programs, promising to successfully link these programs with food bank initiatives among implementing countries.

Along with environmental pollutions, urban planning has been connected to public health. The research indicates that the quality of built environments plays an important role in reducing mental disorders and overall health. The structure and shape of the city are considered as one of the factors influencing happiness and health in urban communities and the type of the daily activities of citizens. The aim of this study was to promote physical activity in the main structure of the city via urban (...) design in a way that the main form and morphology of the city can encourage citizens to move around and have physical activity within the city. Functional, physical, cultural- social, and perceptual-visual features are regarded as the most important and effective criteria in increasing physical activities in urban spaces based on literature review. The environmental quality of urban spaces and their role in the physical activities of citizens in urban spaces were assessed by using the questionnaire tool and analytical network process (ANP) of structural equation modeling. Further, the space syntax method was utilized to evaluate the role of the spatial integration of urban spaces on improving physical activities. Based on the results, the consideration of functional diversity, spatial flexibility and integration, security, and the aesthetic and visual quality of urban spaces plays an important role in improving the physical health of citizens in urban spaces. Further, more physical activities, including motivation for walking and consequently, the sense of public health and happiness, were observed in the streets having higher linkage and space syntax indexes with their surrounding texture.

The paradoxical phenomena of hyperthermia-induced vasoconstriction, hyperthermia-induced hypothermia, and hyperthermia induced arterial vasoconstriction have been observed in animal heatstroke clinical case studies. We attempt to explain the basic mechanism behind such findings in terms of the principle of body heat conservation and natural countermeasure against heat exposure through reduction in the extent of vascular surface area exposed. Hyperthermia-induced vasoconstriction is a paradoxical physiological phenomenon that has limited explanation and exploration in research, despite being observed in clinical case studies. The bodily (...) response of vasoconstriction and vasodilation to increased heat loss and gain work on the principle that heat transfer through the amount of vascular surface area exposed can be moderated in order to be minimised or maximised. Hyperthermia-induced vasoconstriction likely transitions from the break point of maximal limit of vasodilation to counter further rapid heat loss beyond this point. We also propose an explanation of this physiological counter mechanism from the perspective of body core-peripheral steep temperature gradient reduction during hyperthermia or extreme temperature conditions and a spontaneous tendency to avoid unstable blood pressure perturbation. One study which examined the outcome of heating a rabbit's carotid artery produced graded vasoconstriction which is proportional to temperature increase (Mustafa, Thulesius, & Ismael, 2004). These interesting results point out a spontaneous physiological counteractive measure to minimise organ and/or arterial surface area heat exposure through extreme vasodilation by inducing vasoconstriction to counter against persistent excessive heat loss from rapidly increasing temperature of internal organ(s) to the ambient environment, as well as to restore and re-elevate the simultaneous significant arterial blood pressure reduction due to extreme heat gain.

In a recent case-control study by Zimny et al. (2021), the development of unruptured cerebral artery aneurysm can be reasonably traced to the combined factor of high wall shear stress and wall shear stress gradient. In addition, regions of bifurcation apices with such factor of significant wall shear stress are critical in aneurysm formation. A consideration of directional and spatial changes in opposition against the inertia and seamless hemodynamic blood flow in approaching the juncture of bifurcation apex that increase interaction (...) of contact forces between arterial walls and blood volume may aid in further discussion of causality.

Background: The feeding modalities applied in countries with school meal programs are varied because these are shaped not only by the national commitments to alleviate food insecurity among children but also by resource availability from national and international agencies. In terms of financial resources, the USA plays a consistent role in providing donations, grants, loans, and loan guarantee programs to support global school feeding. The U.S. Department of Agriculture (USDA) oversees these funding sources for international school meal programs. Aim: This (...) study aims to examine the moderating effect of USDA funding on the relationship between supply purchasing methods and feeding modalities among countries implementing school meal programs. Methods: The Bayesian Mindsponge Framework, combining the reasoning strengths of Mindsponge Theory and inference advantages of Bayesian analysis, was employed on a dataset of 126 government representatives who manage large-scale school meal programs in 126 different countries. Results: The findings indicated that USDA funding has the potential to positively moderate the relationship between foreign supply purchases and the feeding modalities of school meal programs. However, the direct association between foreign purchases and feeding modalities was unclear. Conversely, while USDA funding was found to have a negative moderation effect on the relationship between domestic supply purchases and feeding modalities, it is these domestic purchases that show potential for positively influencing the feeding modalities. Conclusions: Findings underscore the importance of supporting the World Bank and World Food Programme’s recommendation to rely more on local resources and capacities for developing long-term and sustainable school meal programs. Further exploration of the impact of foreign supply purchases on feeding modalities is needed. Formulating strategic plans to better leverage USDA funding for enhancing domestic supply purchases is highly recommended. (shrink)

Since the stone age humankind has created masterworks which possess a mysterious quality of solidity and grandeur or monumentality. A Paleolithic Venus and a still life by Cezanne both share this monumentality. Michelangelo likened monumentality to sculptural relief, Braque called monumentality 'space', and Hans Hoffman, himself one of the masters, called monumentality 'pictorial depth.' The masters agreed on the import of monumentality, but none of them left a clear explanation of it. In 1943 Earl Loran published his classic book on (...) Cezanne's pictorial structure but, as I demonstrate, his explanation was misleading. This book provide a clear explanation, as did an earlier book by Robert Casper. This book also traces some history of monumentality with reproductions. It also explains how some painters achieved monumentality and how a student can attempt it. Pictorial space is created in the tension between pairs of opposing planes. Opposing planes pull against each other, each containing the other, paradoxically, within the flat surface of the canvas. Sculpture also can be 'plastic': opposing masses pull against each other, each containing the other and creating tension in the space which lies between them. Painting has other aspects like subject matter, expression, style and technique but pictorial space does not depend on these. Monumentality moves us profoundly and apparently has done so since the Paleolith. Using patients' vignettes, I show that there are profound parallels between the structure of a monumental work of art and the structure of an evolving personality. In Winnicott's words, such a personality has 'depth ... an interior space to put beliefs in ... an inside ... a space where things can be held ... the capacity to accept paradox [to contain opposites] ... room and strength ... and originality and the acceptance of tradition as the basis for invention'. A monumental painting also meets this description. I argue that monumental art provides a visual portrait of an evolving personality just as myth, as Freud and Jung both showed, provides a narrative portrait of an evolving personality. An evolving personality is perhaps humankind's most important creation; an underlying purpose of both myth and art is to help us achieve it. I demonstrate in this book that monumental art represented the evolving personality since at least 35,000 BC. Thus to understand monumentality is to better understand the personality and its history.

In an online, participatory class, we interpreted The Dream of the Tabby Cats knowing nothing of the dreamer beyond age and gender, and having none of the dreamer’s associations. Our interpretation included a series of predictions about the dreamer. When it was complete, we asked the bringer of the dream (who had until then been silent and was not visible to us) to give us more information about the dreamer. Later the dreamer herself gave us more information. Of six predictions (...) four were confirmed. The dreamer’s apartment is repeatedly disturbed and, each time, a new cat appears. This record is another iteration of an experiment that will be described more fully in the paper The Dream of the Six-Legged Dog: An Experimental System to Test Meaning, soon to be published. This iteration repeats and confirms the evidence given in that paper. AUDIO RECORD OF CLASS AVAILABLE: link is on first page of the paper you download from this page. (shrink)

This paper integrates symbolic thought and experimental research. We hypothesized that symbolic narratives provide homeostasis for the complex adaptive system that is personality. Our interpretation of a dream was based, in part, on this hypothesis. We found that the dream retold the myth of Saturn. When, by direct experiment, we tried to falsify our interpretation, our results supported our interpretation and thereby supported our hypothesis. Previously, evidence for this hypothesis had been only anecdotal. __________________________________________ For an audio-record of entire class: (...) link is given on 1st page of the text you download from this page.

Healthy eating has long been a focus of professionals and researchers, both to evaluate strategies for improvement and to gain a deeper understanding of its dynamics in order to develop effective promotion methods. This study aims to examine the roles of individuals’ information-seeking abilities and e-health literacy in fostering a healthy eating intention among Iranians. Employing Bayesian Mindsponge Framework analytics on a dataset of 9,755 Iranian participants, the study found positive associations between healthy eating information-seeking ability, e-health literacy, and healthy (...) eating intention among Iranian adults. However, the moderating effect of e-health literacy on the relationship between information-seeking ability and healthy eating intention remains ambiguous. We suggest that enhancing individuals' healthy eating information-seeking abilities and e-health literacy, alongside improving the availability, affordability, and accessibility of reliable healthy eating information, is essential for fostering healthy eating intentions.

Bribing doctors for preferential treatment is rampant in the healthcare system of developing countries like Vietnam. Although bribery raises the out-of-pocket expenditures of patients, it is so common to be deemed an “envelope culture.” Given the little understanding of the underlying mechanism of the culture, this study employed the mindsponge theory for reasoning the mental processes of both patients and doctors for why they embrace the “envelope culture” and used the Bayesian Mindsponge Framework (BMF) analytics to validate our reasoning. Analyzing (...) responses from 1042 Vietnamese patients, we discovered that bribing doctors can help patients reduce the destitution risk induced by treatment. Such effect of doctor bribery remains consistent among patients that have to pay high daily costs (e.g., accommodation and subsistence fees) regardless of their employment status. Nevertheless, for patients with no or unstable jobs, their risks of destitution increase if they have to pay more thank-you money. These findings suggest that doctor bribery is an adaptive strategy for patients in an environment where the healthcare supply cannot meet the actual demand. Moreover, healthcare equity is greatly exacerbated due to the envelope culture, as vulnerable individuals are exposed to a greater threat of poverty. At the same time, those with good economic conditions get preferential treatment by paying a higher amount of thank-you money. Healthcare workers’ ethics must be the top priority for an equitable and proper healthcare system. (shrink)

Although global awareness of environmental challenges is increasing, modern healthcare systems marginalize nature-based healing practices. This paper advocates for a renewed integration of healthcare and the natural world by highlighting the cultural, historical, and scientific foundations of natural healing. Through a multidisciplinary synthesis spanning ethnobotany, public health, and ecological psychology, we examine how home gardens serve as practical embodiments of an eco-surplus culture—a worldview that positions nature as foundational to human well-being and planetary sustainability. Home gardens offer measurable health benefits, (...) such as stress reduction, immune enhancement, biodiversity conservation, and climate resilience. Drawing on diverse case studies—from Indigenous land-based healing to immigrant communities preserving ethnomedicine—we show how gardening fosters physical, psychological, and cultural health. The paper concludes by proposing integrative care models that align biomedical treatments with nature-based interventions and calls for policy innovations that recognize gardens as essential health infrastructure. Reimagining home gardens in this way opens new pathways toward more holistic, equitable, and sustainable approaches to wellness. (shrink)

Background: Transgender health care is a subject of much debate among clinicians, political commentators, and policy-makers. While the World Professional Association of Transgender Health (WPATH) Standards of Care (SOC) establish clinical standards, these standards contain implied ethics but lack explicit focused discussion of ethical considerations in providing care. An ethics chapter in the SOC would enhance clinical guidelines. Aims: We aim to provide a valuable guide for healthcare professionals, and anyone interested in the ethical aspects of clinical support for gender (...) diverse and transgender people of all ages. Recognizing that the WPATH is a global association, we address broad challenges. We offer a reflection on general ethical principles, providing conceptual tools for healthcare providers, patients, and families to navigate the specific challenges they might encounter in transgender health care, in line with WPATH’s worldwide mission and scope. Method: This article employs a descriptive analysis, and our framework of reference is the four principles of biomedical ethics: respect for autonomy, beneficence, nonmaleficence, and justice. Results: The article presents a discussion on the four ethical principles as applied to transgender health care. We address issues such as respect for patient autonomy in decision-making, the role of beneficence and nonmaleficence in clinical interventions, and the importance of justice in equitable treatment and access to care. Some of the ethical concerns we address in this article pertain to the current sociopolitical climate, where there has been increasing legal interference, internationally, for transgender and nonbinary people, particularly youth, seeking medical care. Discussion: We highlight the interplay between ethical principles and clinical practice, underscoring the need for ethical guidance in addressing the diverse challenges faced by healthcare providers and patients in transgender health care. We advocate for continuous refinement of ethical thinking to ensure that transgender health care is not only medically effective but also ethically sound. (shrink)

The meaning of being healthy is widely debated, with many suggesting it is a multidimensional concept encompassing key dimensions such as the absence of disease, the presence of well-being, and a healthy lifestyle. While recent studies indicate that lifestyle may be a dominant dimension, it remains unclear whether this holds true across populations or if significant differences exist, particularly between laypeople and healthcare professionals. Our studies reveal a difference, but surprisingly, in the opposite direction of what the literature would predict: (...) medical professionals are substantially more likely than laypeople to frame discussions of “healthy” and “unhealthy” in lifestyle contexts. This result challenges prevailing assumptions about the biomedical focus of healthcare professionals and has implications for improving health communication. (shrink)

Gallbladder disease commonly affects the general population of Western developed nations and the standard surgical treatment of laparoscopic cholecystectomy normally follows severe cases of this condition. However, the negative health and life quality consequences of this standard line of treatment are lesser known and stand the chance of being taken lightly by healthcare professionals. Complications include bile duct injury, dropped gallstones and a second open invasive surgery, of which could be life threatening for some rare cases. It is, therefore, necessary (...) to highlight the limitations of such a procedure and the need for improvement and widening of the range of treatment options for vulnerable members of the patient population. Additionally, here is a brief overview introduction of a new procedure called endoscopic ultrasound guided gallbladder drainage with promising success rates that can be a potentially feasible alternative to traditional surgical procedures to offer gallbladder disease patients.

Today, we have a mixture of young and older individuals, people with special needs, and people who can care for themselves. Over 1 billion people are estimated to be disabled; this figure corresponds to about 15% of the world's population, with 3.8% (approximately 190 million people) accounting for people aged 15 and up (Organization, 2011). The number of people with disabilities is upward due to the increase in chronic health conditions and many other things. These and other factors have made (...) the need for proper care facilities urgent in today's society. Several care facilities are built to help people with disabilities live their everyday lives and not be left out of the community. (shrink)

Artificial intelligence is now widely accessible and already being used by healthcare researchers throughout various stages in the research process, such as assisting with systematic reviews, supporting data collection, facilitating data analysis and drafting manuscripts for publication. The most common AI tools used are forms of generative AI such as ChatGPT, Claude and Gemini. Generative AI is a type of AI that can generate human-like text, audio, videos, code and images based on text-based prompts inputted by a human user. Generative (...) AI is trained on large amounts of data, and the outputs are sophisticated and can be indistinguishable from a response from a skilled human. In this article, we outline several AI applications that can be used in healthcare research, examining their benefits, limitations and outline best practices for maintaining research integrity and ethical standards.

Despite its crucial role, sample representativeness remains a controversial topic in medical science methodology. There is an ongoing debate not only about how best to define and ensure the representativeness of a sample (e.g., Rudolph et al., 2023; Porta, 2016), but also about whether representativeness is worth pursuing at all (e.g., Rothman et al., 2013). We present a new definition of representativeness in terms of causal models and argue that it is more precise and more useful than existing alternatives. We (...) use examples to demonstrate the types of evidence that can support assumptions of representativeness. (shrink)

The concept of health has long been debated in philosophy and medicine, with discussions often centering on whether health is merely the absence of disease (negativism) or requires the presence of some positive state or ability (positivism). Empirical studies on the folk concept remain scarce and inconclusive. This paper investigates the folk concept of health through implication and contradiction tests. Our findings reveal that while people often infer that health entails both a disease-free state and lifestyle-related factors, interpretations of ‘health’ (...) vary significantly depending on context, with participants associating health primarily with the absence of disease in medical settings while emphasizing lifestyle factors like diet and activity in personal training scenarios. These results suggest that the meaning of the folk concept of health is strongly context-dependent. (shrink)

This study explores experiences of ex-incels—men who have withdrawn from incel communities—through eleven qualitative interviews analysed using R.W. Connell’s hegemonic masculinity (HM) framework. Findings reveal some ex-incels adopt flexible masculinities, while others struggle with prescriptive norms perpetuated by the anti-feminist ‘manosphere’. Findings spotlight identity reconstructions, where men both reject and remain influenced by rigid archetypes, performing hybrid masculinities. This study deepens understanding of incel ideology, its impact on identity, and interplay between inceldom and masculinities via contributing to hybrid masculinities theorising. (...)

In the rural regions of New England, naturally occurring arsenic in bedrock poses a silent but serious threat to households dependent on private wells. Unlike public water systems regulated by authorities, private well users bear sole responsibility for monitoring water quality.

As wildfires intensify across North America, they leave more than scorched earth in their wake. Invisible clouds of fine particulate matter—PM₂.₅, measuring 2.5 microns or smaller—travel vast distances, infiltrating lungs and triggering serious health consequences [2-4].
