Social isolation in COVID-19: a comparative study between Korea and Vietnam. BMC Public Health 2023; 23:1556. [PMID: 37582702 PMCID: PMC10428539 DOI: 10.1186/s12889-023-16491-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2023] [Accepted: 08/09/2023] [Indexed: 08/17/2023] Open
Abstract
Amidst the ongoing COVID-19 pandemic, social isolation has become a pressing issue worldwide, deeply affecting individuals' mental and physical well-being. This study introduces a theoretical model to understand the factors influencing social isolation in the context of this global health crisis. We employed a survey methodology, collecting data from Korean and Vietnamese university students through a Google survey form. The theoretical model was evaluated using structural equation modeling (SEM), and multi-group analysis (MGA) was used to assess differences between the Korean and Vietnamese student groups. The investigation centered on affective risk perception, cognitive risk perception, social distancing attitude, social distancing intention, and demographic factors like age and gender. Our findings revealed that affective and cognitive risk perceptions have significant positive impacts on attitudes toward social distancing. Furthermore, attitudes towards social distancing were found to significantly influence social distancing intentions. Interestingly, social distancing intention was found to have a significant positive correlation with social isolation. Lastly, demographic factors such as gender and age were found to be significant factors influencing social isolation. Specifically, gender had a positive association, while age showed a negative correlation with social isolation. Moreover, our MGA results showed that the relationship between social distancing intention and social isolation significantly differed between the Korean and Vietnamese student groups, indicating potential cultural or societal influences on this relationship. Such understanding could inform policies and strategies aimed at mitigating the adverse effects of social isolation in the wake of global health crises.

Cross-cultural differences in retracted publications of male and female from a global perspective. Scientometrics 2023; 128:3805-3826. [PMID: 37287880 PMCID: PMC10183084 DOI: 10.1007/s11192-023-04717-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2021] [Accepted: 04/21/2023] [Indexed: 06/09/2023]
Abstract
The aim of this paper is threefold: (i) to identify the combinations of national culture dimensions that lead to high (or low) male or female retracted publications, (ii) to understand the role of personal trust as a relevant condition that combines with national culture dimensions to cause high (or low) male or female retraction, and (iii) to identify the differences in the configurations that lead to those outcomes. Based on framework of Hofstede's cross-cultural analysis and data from Hofstede Center, World Value, and Web of Science, this essay analyzes cultural complex causal relations between national culture and trust dimensions (conditions), and male and female retracted publications (outcomes) in 30 countries nationally and globally by fuzzy-set qualitative comparative analysis. This research provides three major insights: (i) Cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance, long-term orientation) and trust are not necessary conditions for both male and female to cause retractions, (ii) different levels of personal trust (high/low) combine with national cultural dimensions in order to produce different configurations that can lead to high or low retractions, and (iii) Each gender causes retractions in a similar or identical way, but each also owns its unique way. Finally, we provide effective policy recommendations to specific countries based on our critical conclusions and discussions.

From "content" to "competence": A cross-cultural analysis of pedagogical praxis in a Chinese science lesson. PROSPECTS 2023:1-19. [PMID: 37360046 PMCID: PMC10008194 DOI: 10.1007/s11125-022-09630-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Accepted: 12/12/2022] [Indexed: 03/28/2023]
Abstract
This research is based on an approach that looks at cross-cultural research design as a "lens" for a deeper understanding of what goes on in the classroom. The research question is how a cross-cultural study like this one can lead to identifying the cultural script of teaching and help educators reflect on their practice. In this context, Chinese lessons could be described as a case-based study of pedagogical reasoning that drives a shift from focusing on "content" to "competence". This article draws on qualitative data collected by the researchers and a cross-cultural analysis of a science lesson in an elementary school in Beijing, China. Using the Japanese educators' critiques and Chinese reviews, the article determines the cultural script of teaching science (the first research question) and the way Chinese teachers reflect on their practice through the Japanese lens (the second research question). This study exposes the importance of teachers' understanding and reflecting on their practice, technically, practically, and critically. The analysis results show how teachers learn to change their lenses, to reflect on their teaching and reconstruct their understanding about teacher professionalism through at least four basic elements: didactics, praxis, pedagogy, and theory.

Being More Educated and Earning More Increases Romantic Interest: Data from 1.8 M Online Daters from 24 Nations. HUMAN NATURE (HAWTHORNE, N.Y.) 2022; 33:115-131.

Abstract
How humans choose their mates is a central feature of adult life and an area of considerable disagreement among relationship researchers. However, few studies have examined mate choice (instead of mate preferences) around the world, and fewer still have considered data from online dating services. Using data from more than 1.8 million online daters from 24 countries, we examined the role of sex and resource-acquisition ability (as indicated by level of education and income) in mate choice using multilevel modeling. We then attempted to understand country-level variance by examining factors such as gender equality and the operational sex ratio. In every nation, a person’s resource-acquisition ability was positively associated with the amount of attention they received from other site members. There was a marked sex difference in this effect; resource-acquisition ability improved the attention received by men almost 2.5 times that of women. This sex difference was in every country, admittedly with some variance between nations. Several country-level traits moderated the effects of resource-acquisition ability, and in the case of unemployment this moderating role differed by sex. Overall, country-level effects were more consistent with evolutionary explanations than sociocultural ones. The results suggest a robust effect of resource-acquisition ability on real-life mate choice that transcends international boundaries and is reliably stronger for men than women. Cross-cultural variance in the role of resource-acquisition ability appears sensitive to local competition and gender equality at the country level.

Human spatial memory is biased towards high-calorie foods: a cross-cultural online experiment. Int J Behav Nutr Phys Act 2022; 19:14. [PMID: 35144639 PMCID: PMC8832830 DOI: 10.1186/s12966-022-01252-w] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2021] [Accepted: 01/31/2022] [Indexed: 11/22/2022] Open
Abstract
Background Human memory appears to prioritise locations of high-calorie foods, likely as an adaptation for foraging within fluctuating ancestral food environments. Importantly, this “high-calorie bias” in human spatial memory seems to yield consequences for individual eating behaviour in modern food-abundant settings. However, as studies have mainly been conducted in European (Dutch) populations to date, we investigated whether the existence of the cognitive bias can be reasonably generalised across countries that vary on culturally-relevant domains, such as that of the USA and Japan. Furthermore, we investigated whether sociodemographic factors moderate the expression of the high-calorie spatial memory bias in different populations. Methods In a cross-cultural online experiment, we measured the food location memory of diverse participants from the USA (N = 72; 44.4% Male; 54 ± 15.99 years) and Japan (N = 74; 56.8% Male; 50.85 ± 17.32 years), using a validated computer-based spatial memory task with standardised images of high-calorie and low-calorie foods. To directly compare the magnitude of the high-calorie spatial memory bias in a broader cultural scope, we also included data from a previous online experiment that identically tested the food spatial memory of a Dutch sample (N = 405; 56.7% Male; 47.57 ± 17.48 years). Results In the US sample, individuals more accurately recalled (i.e. had lower pointing errors for) locations of high-calorie foods versus that of low-calorie alternatives (Mean difference = -99.23 pixels, 95% CI = [-197.19, -1.28]) – regardless of one’s hedonic preferences, familiarity with foods, and encoding times. Likewise, individuals in the Japanese sample displayed an enhanced memory for locations of high-calorie (savoury-tasting) foods (Mean difference = -40.41 pixels, 95% CI = [-76.14, -4.68]), while controlling for the same set of potential confounders. The magnitude of the high-calorie bias in spatial memory was similar across populations (i.e. the USA, Japan, and the Netherlands), as well as across diverse sociodemographic groups within a population. Conclusions Our results demonstrate that the high-calorie bias in spatial memory transcends sociocultural boundaries. Since the cognitive bias may negatively impact on our dietary decisions, it would be wise to invest in strategies that intervene on our seemingly universal ability to efficiently locate calorie-rich foods.

Media and interpersonal channels uses and preferences during the COVID-19 pandemic: the case of the United States, Thailand, and Croatia. Heliyon 2021; 7:e07555.

Abstract
According to media systems dependency theory, increased dependence on media to meet individual needs is directly proportional to greater perceived media importance in one's life and subsequently stronger media effects on one's attitudes and behavior. This dependency relationship intensifies during times of uncertainty or crisis. Although several recent studies have focused on media dependence during health crises such as SARS and H1N1 influenza, insights from eastern countries may not be validated in other hemisphere. Therefore, the purpose of the current study was to adopt a cross-cultural lens to examine how participants from three different continents used media during the COVID-19 pandemic. In total, 860 adults completed a survey during April and May 2020. Participants were asked to provide demographic and socioeconomic details, followed by questions measuring their media consumption, channel preferences, motivations, and perception of their well-being during the COVID-19 pandemic. Results revealed that national culture had a strong influence on media use and preferences during the COVID-19 crisis. For example, the US participants spent the most time using the media but scored the lowest on well-being. This aligns with the claim that in individualistic countries people rely on media more than on their social network. US participants also used the media for surveillance goals more than their Thai or Croatian counterparts. Another cultural difference was that Thai participants reported using the media to relax more than other nationalities, which reflects the Thai's “way of life” and can explain their higher score on well-being. Finally, there were cultural differences in the use of social media. While Croatian and Thai participants' use of social media reflected collectivistic tendencies (using social media for social interaction), among Americans, social media use reflects individualistic trends (using social media for surveillance). The study discusses limitations and suggestions for future research.

Abstract
Pictures are often used as stimuli in several fields, such as psychology and neuroscience. However, co-occurring image-related properties might impact their processing, emphasizing the importance of validating such materials to guarantee the quality of research and professional practices. This is particularly relevant for pictures of common items because of their wide applicability potential. Normative studies have already been conducted to create and validate such pictures, yet most of them focused on stimulus without naturalistic elements (e.g., line drawings). Norms for real-world pictures of common items are rare, and their normative examination does not always simultaneously assess affective, semantic and perceptive dimensions, namely in the Portuguese context. Real-world pictures constitute pictorial representations of the world with realistic details (e.g., natural color or position), thus improving their ecological validity and their suitability for empirical studies or intervention purposes. Consequently, the establishment of norms for real-world pictures is mandatory for exploring their ecological richness and to uncover their impact across several relevant dimensions. In this study, we established norms for 596 real-world pictures of common items (e.g., tomato, drum) selected from existing databases and distributed into 12 categories. The pictures were evaluated on nine dimensions by a Portuguese sample. The results present the norms by item, by dimension and their correlations as well as cross-cultural analyses. RealPic is a culturally based dataset that offers systematic and flexible standards and is suitable for selecting stimuli while controlling for confounding effects in empirical tasks and interventional applications.

Medicinal plants for gastrointestinal diseases among the Kuki-Chin ethnolinguistic groups across Bangladesh, India, and Myanmar: A comparative and network analysis study. JOURNAL OF ETHNOPHARMACOLOGY 2020; 251:112415. [PMID: 31917280 DOI: 10.1016/j.jep.2019.112415] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 11/10/2019] [Accepted: 11/17/2019] [Indexed: 05/20/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The Kuki-Chin is a composite ethnolinguistic group made up of many distinct groups and subgroups that are linked by a common history, culture, and population distribution in the Kuki-Chin region, shared geopolitically by Bangladesh, India, and Myanmar. This region is shown to be in a hotspot of digestive disease activity based on official reports and in concordance with data from related ethnopharmacological field surveys. Our work provides a comparative analysis of medicinal plant knowledge for the treatment of gastrointestinal diseases (GAS-Ds) among the Kuki-Chin ethnic groups found across the three countries. AIM OF THE STUDY The objectives were (1) to identify the medicinal plants and herbal therapies for the treatment of GAS-Ds reported in related Kuki-Chin ethnobotanical publications, (2) to find the similarities and differences in medicinal plant knowledge among the country-affiliated groups by comparing plant and disease information, and (3) to determine significant plant taxa and their pattern(s) of use as digestive disease herbal remedies by analyzing disease-plant networks. MATERIALS AND METHODS Secondary data were gathered from 34 related studies through internet search of ethnobotanical information from field studies published in journals, reports, books, and dissertations/theses. These data represented 22 Kuki-Chin ethnolinguistic groups inhabiting 23 districts across six states comprising the Kuki-Chin region: the Chittagong Division (Bangladesh); Mizoram, Assam, Manipur, and Tripura States (India); and Chin State (Myanmar). Scientific names of plants and digestive diseases collated from secondary sources were validated and standardized following the Plant List and the International Classification of Primary Care Second Edition, respectively. RESULTS AND DISCUSSION A total of 482 species in 330 genera and 118 families of vascular plants were recorded for the treatment of 29 standardized GAS-Ds. On the basis of the number of use-reports, regional native species Phyllanthus emblica, Centella asiatica, and Aegle marmelos, as well as the non-natives Carica papaya, Portulaca oleracea, and Psidium guajava were found to be the most preferred. Comparative analysis of medicinal species showed that groups in India revealed the highest number of medicinal plant taxa, followed by those in Bangladesh and Myanmar. The most prevalent GAS-Ds were shown to be abdominal pain epigastric, gastroenteritis presumed infections, and diarrhoea, as supported by the number of use-reports and medicinal taxa used for their treatment, and their informant consensus factor values. Analyses of disease-plant networks graphically showed both GAS-Ds distribution patterns in the region and potential medicinal plant (group) candidates for further studies. CONCLUSION Overall, this study revealed an astonishingly rich diversity of medicinal plants used to treat digestive diseases among the Kuki-Chin. A comparative analysis showed variations and remarkable distinctions in medicinal plant knowledge among country-affiliated groups, as likely influenced by external sociocultural factors and geopolitical barriers, as well as the availability of ethnobotanical data. The use of network analysis reflected not only shared common affinities and patterns of plant use based on the taxonomic composition and species selection, but also disease prevalence and distribution patterns. The information found here can hopefully spur interest among future researchers and policy makers to better improve both the (ethno) medicinal research capacity and healthcare system in the region.

Explaining Fairness : Results from an Experiment in Guinea. HUMAN NATURE (HAWTHORNE, N.Y.) 2019; 30:398-421.

Abstract
Fairness is undoubtedly an essential normative concept in humans and promotes cooperation in human societies. The fact that fairness exists is puzzling, however, because it works against the short-term interest of individuals. Theories of genetic evolution, cultural evolution, and gene-culture coevolution identify plausible mechanisms for the evolution of fairness in humans. Such mechanisms include kin selection, the support of group-beneficial moral norms through ethnic markers, free partner choice with equal outside options, and free partner choice with reputation as well as spite in small populations. Here, we present the results of a common-pool resource game experiment on sharing. Based on data from 37 multiethnic villages in a subsistence agricultural population in Foutah Djallon, Guinea, we show that fair behavior in our experiment increased with increasing ethnic homogeneity and market integration. Group size and kinship had the opposite effect. Overall, fair behavior was not conditional on reputation. Instead, the ability of the different village populations to support individuals' fairness in situations lacking the opportunity to build a positive reputation varied significantly. Our results suggest that evolutionary theory provides a useful framework for the analysis of fairness in humans.

The problem of not waste sorting behaviour, comparison of waste sorters and non-sorters in European Union: Cross-cultural analysis. THE SCIENCE OF THE TOTAL ENVIRONMENT 2019; 672:174-182.

Abstract
In the European Union (EU), 3.3% of respondents declared that they did not sort waste at all. The level of non-sorter behaviour depends on the level of a country's economic development. Referring to Hofstede's cultural dimensions, only power distance, uncertainty avoidance, and indulgence had significant effects on non-sorting behaviour. The non-sorter respondents were less linked to performe waste reducing and reusing behaviours. The tools which convince respondents to begin separating waste or separate wastes more differed between sorters and non-sorters as well. The sorters preferred to trust the level of waste management while non-sorter respondents responded to convenience level. Analysing the determinants of sorting behaviour in separate EU countries, we found that only efforts to reduce waste positively influenced sorting behaviour in major EU countries. Attitudes to resource efficiency positively influenced in one third of EU countries. Meanwhile the knowledge about general and personal waste generation influenced sorting behaviour negatively or insignificantly (except Spain and Hungary). Thus, to promote sorting behaviour, it is not enough to inform people that we have a lot of waste. Therefore, this study has significant implications for waste policy and can help to trigger and promote more sorting behaviour in EU countries.

Social Practice and Shared History, Not Social Scale, Structure Cross-Cultural Complexity in Kinship Systems. Top Cogn Sci 2019; 12:744-765.

Abstract
Human populations display remarkable diversity in language and culture, but the variation is not without limit. At the population level, variation between societies may be structured by a range of macro‐evolutionary factors, including ecological and environmental resources, shared ancestry, spatial proximity, and covarying social practices. Kinship terminology systems are varying linguistic paradigms that denote familial social relationships of kin and non‐kin. Systems vary by the kinds of salient distinctions that are made (e.g., age, gender, generation) and the extent to which different kinds of kin are called by the same term. Here, we explore two kinds of explanations for an observed typology of kin terms for cousins. The first one derives the typology from a learning bottleneck linked to population size. This would lead to a correlation between community size and the type of kinship system. The second one derives it from a set of social practices, particularly marriage and transfer of resources that might shape kinship systems. Using a global ethnographic database of over a thousand societies, we show that marriage rules and shared linguistic affiliation have a significant influence on the type of kinship system found in a society. This remains true if we control for the effect of spatial proximity and cultural ancestry. By combining cognitive and historic approaches to this aspect of kinship, we suggest broader implications for the study of human social cognition in general. Kinship terminologies are basic cognitive semantic systems that all human societies use for organizing kin relations. Diversity in kinship systems and their categories is substantial, but constrained. Rácz, Passmore, and Jordan explore hypotheses about such constraints from learning theories and social pressures, testing the impact of a community‐size driven learning bottleneck against the social coordination demands of different kinds of marriage and resource systems.

When Saying "Sorry" Isn't Enough: Is Some Suicidal Behavior a Costly Signal of Apology? : A Cross-Cultural Test. HUMAN NATURE (HAWTHORNE, N.Y.) 2018; 30:117-141.

Abstract
Lethal and nonlethal suicidal behaviors are major global public health problems. Much suicidal behavior (SB) occurs after the suicide victim committed a murder or other serious transgression. The present study tested a novel evolutionary model termed the Costly Apology Model (CAM) against the ethnographic record. The bargaining model (BRM) sees nonlethal suicidal behavior as an evolved costly signal of need in the wake of adversity. Relying on this same theoretical framework, the CAM posits that nonlethal suicidal behavior can sometimes serve as an honest signal of apology in the wake of committing a severe transgression, thereby repairing valuable social relationships. To test this hypothesis, the CAM was operationalized into a set of variables, and two independent coders coded 473 text records on suicidal behavior from 53 cultures from the probability sample of the Human Relations Area Files. The results indicated that in ethnographic accounts of suicidal behavior, transgressions, punishment, and shame were relatively common, supporting the CAM, but explicit motives to apologize and evidence of forgiveness were rare, contrary to the CAM. The theoretical variables of the CAM nevertheless formed a cluster distinct from the BRM, and a subset of cases of suicidal behavior were largely related to transgressions and other CAM variables rather than BRM or other variables. Support for the CAM varied widely across cultures, but there was evidence for it in every major geographical region. Exploratory analyses suggested that the CAM is potentially more likely to occur in response to severe conflicts concerning transgressions committed against nonkin. Furthermore, in text records that involved transgressions, male suicidal behavior was most frequently associated with murder, whereas female suicidal behavior was most frequently associated with sexual transgressions. In conclusion, the results provided mixed support for the hypothesis that some instances of suicidal behavior function to send a costly signal of apology to those harmed by a transgression.

Abstract
Certain social context features (e.g., maternal presence) are known to increase young children's exploration, a key process by which they learn. Yet limited research investigates the role of social context, especially peer presence, in exploration across development. We investigate whether the effect of peer presence on exploration is mediated by age or cultural-specific experiences. We test its impact on exploration across development (2-11 years) and across cultures (United States and the Tsimane', indigenous farmer-foragers in Bolivia). Specifically, peer presence does not boost exploration among young U.S. children and becomes more inhibitory among school-age children. In contrast, peer presence facilitates exploration and provides an additional boost for older Tsimane' children, who differ from U.S. children in their cultural-specific learning experiences (e.g., formal education), among other differences. We discuss potential cultural factors and mechanisms by which peer presence may boost exploratory behavior.
