RESUMO
The present experiment used the trapped rat model to explore whether pharmacological manipulation of distress affects the likelihood of helping behavior. 120 Sprague-Dawley rats (30 male pairs and 30 female pairs) completed 12 consecutive, daily trials assessing helping behavior. During an individual trial, a trapped rat was placed in a restrainer in the center of an open field, while its cagemate could move around freely and possibly open the restrainer by lifting a door. Trapped rats received an intraperitoneal injection of either 1) physiological saline, 2) the anxiolytic midazolam (1.5 mg/kg), or 3) the anxiogenic yohimbine (2.5 mg/kg) 30 min prior to the start of each trial. Dependent variables measured were: 1) door opening latency (sec), 2) percentage of trials in which a door opening occurred, and 3) the number of free rats classified as "openers." Based on emotional contagion theory, we predicted that 1) free rats paired with midazolam-subjects would show attenuated helping behavior (e.g., higher door opening latency) compared to controls, and conversely 2) free rats paired with yohimbine-subjects would show enhanced helping behavior. First, a significant sex-difference was observed, in that more females were classified as openers than males. This supports previous evidence that females express higher altruistic motivation and experience stronger emotional contagion than males. Second, midazolam-treatment significantly attenuated helping behavior. From trials 4-12, free rats paired with midazolam-subjects expressed slower door opening latencies compared to controls. Third, yohimbine-treatment significantly increased helping behavior (e.g., reduced door opening latencies) - but only on trials 1-3; by trials 9-12, this pattern was reversed. These results are consistent with emotional contagion theory and indicate that intensity of distress directly modulates altruistic motivation through vicarious state-matching.
RESUMO
BACKGROUND: In China, community rehabilitation workers are facing a growing challenge related to heavy occupational stress, which is having an impact on employment turnover. Previous studies have explored the effect of the public service motivation of workers in "helping" jobs on occupational stress or turnover intention, but there is a lack of clarification of the impact of altruism on turnover intention in the case of complex pathways involving various factors. METHODS: A stratified sampling method was used, and a total of 82 community rehabilitation workers who assist disabled people from 34 community health centres in Jiangmen city were included in the study from August to October 2022. The turnover intention, occupational stress, burnout, quality of life, altruism, and certain sociodemographic information of community rehabilitation workers were measured using a structured questionnaire. The partial least squares method was employed to construct and test the structural equation model. RESULTS: Although altruism had no direct impact on occupational stress or turnover intention, altruism moderated the effect of occupational stress on burnout (ßMod = -0.208) and quality of life (ßMod = 0.230) and weakened the mediation of burnout and quality of life between occupational stress and turnover intention. CONCLUSIONS: This study proposes to address the dilemma of "strong function" and "weak specialty" in community rehabilitation services and to conduct positive psychological interventions for community rehabilitation workers through the guidance of altruistic values.

Socially living animals can counteract disease through cooperative defences, leading to social immunity that collectively exceeds the sum of individual defences. In superorganismal colonies of social insects with permanent caste separation between reproductive queen(s) and nonreproducing workers, workers are obligate altruists and thus engage in unconditional social immunity, including highly specialised and self-sacrificial hygiene behaviours. Contrastingly, cooperation is facultative in cooperatively breeding families, where all members are reproductively totipotent but offspring transiently forgo reproduction to help their parents rear more siblings. Here, helpers should either express condition-dependent social immunity or disperse to pursue independent reproduction. We advocate inclusive fitness theory as a framework to predict when and how indirect fitness gains may outweigh direct fitness costs, thus favouring conditional social immunity.
RESUMO
Accurately differentiating indeterminate pulmonary nodules remains a significant challenge in clinical practice. This challenge becomes increasingly formidable when dealing with the vast radiomic features obtained from low-dose computed tomography, a lung cancer screening technique being rolling out in many areas of the world. Consequently, this study proposed the Altruistic Seagull Optimization Algorithm (AltSOA) for the selection of radiomic features in predicting the malignancy risk of pulmonary nodules. This innovative approach incorporated altruism into the traditional seagull optimization algorithm to seek a global optimal solution. A multi-objective fitness function was designed for training the pulmonary nodule prediction model, aiming to use fewer radiomic features while ensuring prediction performance. Among global radiomic features, the AltSOA identified 11 interested features, including the gray level co-occurrence matrix. This automatically selected panel of radiomic features enabled precise prediction (area under the curve = 0.8383 (95 % confidence interval 0.7862-0.8863)) of the malignancy risk of pulmonary nodules, surpassing the proficiency of radiologists. Furthermore, the interpretability, clinical utility, and generalizability of the pulmonary nodule prediction model were thoroughly discussed. All results consistently underscore the superiority of the AltSOA in predicting the malignancy risk of pulmonary nodules. And the proposed malignant risk prediction model for pulmonary nodules holds promise for enhancing existing lung cancer screening methods.

RESUMO
RESEARCH QUESTION: What is the profile of women in the USA who become surrogates, and what is their power of decision and motivations? DESIGN: This quantitative study was performed with 231 participants in the USA, given the country's long history of surrogacy, to help clarify the profile of women who become surrogates, their power of decision and motivations. RESULTS: Descriptive and multivariate cluster analyses showed that women who become surrogates earn above the average income for their state of residency, have a high level of education, have health insurance, are employed, and decide to become a surrogate for prosocial/altruistic reasons. CONCLUSIONS: In contrast to the premise of both radical feminism and ultra-conservative Catholicism, this study found that altruism and empathy are the primary motivations for participating in surrogacy processes, and that a woman's decision to become a surrogate is not motivated by social conditioning relating to poverty or social status.
RESUMO
INTRODUCTION: Professionalism is fundamental to the existence of professions. In pharmacy, interest in this theme improved with events that examined the resocialization of pharmacists in care. With this, evaluating professionalism can help the operationalization of the theme and, consequently, the development of strategies for pharmacy consolidation before its challenges. Therefore, this study aimed to evaluate the professionalism of Brazilian pharmacists. METHODS: To meet the objective, a cross-sectional study was conducted between March 2022 and August 2023. Data were collected using the Brazilian version of the "Modification of Hall's Professionalism Scale for Use with Pharmacists". The scale has 39 items grouped into the domains: autonomy, vocation, professional council, self-regulation, continuing education, and altruism. Data were analyzed using descriptive statistics and an ANOVA analysis of variance with post-hoc Hochberg or Games-Howell tests with Bootstrapping was conducted to verify differences between groups. RESULTS: 600 pharmacists participated in this study. The majority (69%) was female and carried out their professional activities in community pharmacies (50%). Professionalism scores ranged between 14 and 29 points, with an average of 22.8 points. Pharmacists working in outpatient clinics had higher scores in most factors, namely, altruism, continuing education, professional council, vocation, and autonomy. This indicates that the inclination of pharmacists to occupy areas focused on care can be significant to assess professionalism. CONCLUSIONS: The data obtained indicate that pharmacists working in outpatient clinics had higher professionalism scores compared to others. This corroborates the worldwide trend experienced by pharmacy in recent decades, which is the execution of increasingly patient-centered practice models.

AIM: The aim of the current research is to determine nursing students' levels of altruism, attitudes towards medical errors and the effect of altruism on attitudes towards medical errors. BACKGROUND: Nursing students should be aware of medical errors and have an attitude towards correcting them. Professional values play an essential role in changing, shaping and developing attitudes in nursing students. Altruism is one of the most important determining professional values in students' professional success and development of attitudes towards different situations. DESING: This study is a descriptive and cross-sectional study. METHODS: The research was conducted in the Nursing Department of a state university in Turkey and the study population consisted of 2nd, 3rd and 4th year nursing students (N=375) who were continuing their education and clinical practice in the spring semester of the 2022-2023 academic year. The study was completed with 321 students. The data were collected online using the information form, the Altruism Scale and the Scale of Attitudes Towards Medical Errors via Google Forms between 01 and 31 May 2023. Data were analysed using descriptive statistics, Independent-Samples t-test, One-Way ANOVA test, Pearson's correlation analysis and simple linear regression. RESULTS: Students had a mean score of 69.68 (range 40-98) on the Altruism Scale and 3.82 (range 2.38-4.56) on the Scale of Attitudes Towards Medical Errors. A significant, very weak positive correlation was found between the Altruism Scale and the total mean scores of the Attitudes Towards Medical Errors Scale (p=0.001). Altruism was found to have a significant effect on attitude towards medical errors (p=0.001). The explanatory power of the regression model was 0.101 and altruism explained 10.1â¯% of the students' attitudes towards medical errors scores. CONCLUSIONS: Students have positive attitudes towards medical errors, high awareness of the importance of medical errors and error reporting and above average levels of altruism. Altruism has a positive effect on attitudes towards medical errors.
RESUMO
BACKGROUND: Does experiencing adversity engender kindness, and if so, for whom? Two studies tested the hypothesis that adversity predicts increased pro-social outcomes, and that this relationship is strongest for individuals who view others as good and trustworthy, or benevolent. METHOD: In Study 1, a cross-sectional survey design was utilized, and in Study 2 a longitudinal survey was conducted. RESULTS: In Study 1 (N = 359), the number of lifetime adverse life events was associated with increased volunteering, empathic concern, and self-reported altruism. The association of adversity and altruism was stronger for those with greater benevolence beliefs. In Study 2 (N = 1157), benevolence beliefs were assessed, and in subsequent years, adverse life events were reported. The number of past-year adverse life events predicted more volunteering and charitable involvement, but only among people with high benevolence beliefs. CONCLUSION: Exposure to adversity may be associated with increased pro-social behavior among those with higher benevolence beliefs. In part, this could be due to benevolence beliefs increasing the expectation that one's efforts will be appreciated and reciprocated.
RESUMO
Humans cooperate in groups in which mutual monitoring is common, and this provides the possibility of third-party arbitration. Third-party arbitration stabilizes reciprocity in at least two ways: first, when it is accurate, it reduces the frequency of misunderstandings resulting from perception errors, and second, even when it is inaccurate, it provides a public signal that allows pairs to align their expectations about how to behave after errors occur. Here, we describe experiments that test for these two effects. We find that in an iterated, sequential Prisoner's Dilemma game with errors, players with the highest average payoffs are those who make use of third-party arbitration and who also employ forgiving strategies. The combination of these two behaviours reduces the detrimental effects of errors on reciprocity, resulting in more cooperation.

To develop effective private donation campaigns that support vaccine distribution in low- and middle-income countries (LMICs), one must understand donors' willingness to give, response to stimuli, and preferences for program management. We use a contingent valuation method to estimate United States citizens' willingness to give to nongovernmental COVID-19 immunization programs in LMICs during the emergency phase of the pandemic. Using split-sample treatments, we evaluate the impact of the immunization program administrator (generic NGO or COVAX) and the role of priming communications on inequality in income and vaccination rates between the US and recipient countries. Results show that the median American would donate $42 towards global immunization programs. Preferences for program management and responses to priming communications are heterogeneous across political affiliations, after controlling for altruistic motives, experiences with COVID, giving behaviors, and sociodemographic characteristics. Specifically, Democrats and Independents are more likely to donate to the COVAX-administered fund, and more responsive to priming statements regarding vaccine-gaps. Policy implications are discussed.
RESUMO
Introduction: This study examined the underlying mechanism of the relationship between downward social comparison (DSC) and altruism through two conceptually important but rarely studied factors: belief in a just world (BJW) and general life satisfaction (GLS). Methods: The study utilized a two-time-point design, spaced 2 months apart, with a sample of 1,764 college students from China. The study measured DSC, altruism, BJW, and GLS. Results: The findings revealed a significant positive predictive effect of DSC on college students' altruism and belief in a just world (BJW). Notably, GLS emerged as a multi-mediating factor in this relationship. The study also revealed that both subscales of BJW, namely personal belief in a just world (PBJW) and general belief in a just world (GBJW), played distinct roles in the mediation model. PBJW exhibited a stronger mediating effect, suggesting that DSC can foster individual altruism and BJW. Particularly, BJW was identified as enhancing GLS, subsequently promoting altruistic behavior. Conclusion: This study contributes to the existing literature on social comparison by shedding light on the relationship between DSC, altruism, and the mediating role of belief in a just world and GLS. The findings underscore the potential for promoting altruistic behavior among college students through interventions targeting beliefs in a just world, especially at the personal level, and enhancing GLS.
RESUMO
Clinical researchers should help respect the autonomy and promote the well-being of prospective study participants by helping them make voluntary, informed decisions about enrollment. However, participants often exhibit poor understanding of important information about clinical research. Bioethicists have given special attention to "misconceptions" about clinical research that can compromise participants' decision-making, most notably the "therapeutic misconception." These misconceptions typically involve false beliefs about a study's purpose, or risks or potential benefits for participants. In this article, we describe a misconception involving false beliefs about a study's potential benefits for non-participants, or its expected social value. This social value misconception can compromise altruistically motivated participants' decision-making, potentially threatening their autonomy and well-being. We show how the social value misconception raises ethical concerns for inherently low-value research, hyped research, and even ordinary research, and advocate for empirical and normative work to help understand and counteract this misconception's potential negative impacts on participants.
RESUMO
PURPOSE: In this survey, we aimed to provide the description of previous oocyte donors' profile in a Belgian tertiary fertility hospital clinic. The research question is as follows: could certain aspects be changed or improved, according to previous oocyte donors? The final purpose is to boost adherence to future oocyte donation (OD) programs, given the large gap between supply and demand. METHODS: We set up an observational cross-sectional study of oocyte donors who were recruited in a tertiary referral hospital. Participants were asked to join an anonymous online survey with questions about demographic and reproductive variables, reasons to start or discontinue OD, satisfaction rate, experience, and attitude towards presumed anonymity. RESULTS: A total of 218 women were eligible to join the study, with a response rate of 49% (108/218). The emerging profile of the oocyte donor is a well-educated (102/108 with at least a high school degree), employed (86/108) woman in her thirties. Altruism and solidarity were the main drivers of their choice (105/108), and a general permissive attitude towards disclosure of their personal information to the recipient (60/108) was registered. In case of negative experience or discontinuation, concerns regarding pain management and specific long-lasting psychological support were expressed (8/20). CONCLUSIONS: Our findings suggest the need to improve pain relief and to offer psychological support even beyond ending the donation process. These interventions could improve both participation and adherence to OD programs, ensuring an autonomous and free choice while avoiding any risk of exploitation.
RESUMO
BACKGROUND AND OBJECTIVES: Prosociality refers to voluntary behaviors that intend to benefit others. Most of the existing literature suggests that older adults tend to act more prosocially compared to younger adults, whereas some studies show that older adults might not be that prosocial under certain conditions. The current study aimed to summarize the mixed findings and quantify the age difference in prosociality by conducting a qualitative systematic review and a quantitative meta-analysis. RESEARCH DESIGN AND METHODS: Literature search was conducted based on 5 databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed and this review was registered at PROSPERO (CRD42022333373). RESULTS: Based on the qualitative synthesis of 51 studies, older adults (n = 109,911) were more prosocial than younger adults (n = 68,501). The meta-analysis of 46 studies further supported this age effect (Hedges' g = 0.31, 95% confidence interval [0.24, 0.37]), and this age effect might be moderated by the types of prosociality. We discovered a moderate age effect in sharing (Hedges' g = 0.53), but a nonsignificant age effect in helping (Hedges' g = 0.11), comforting (Hedges' g = -0.20), or mixed prosociality (Hedges' gâ =â 0.15). Additionally, the age effect was only significant when older adults had higher socioeconomic status than younger adults. DISCUSSION AND IMPLICATIONS: Future research should develop more comprehensive measures of prosociality, examine more variables that influence aging and prosociality, and investigate the neural mechanism(s) of prosociality to achieve a thorough understanding of the age difference in prosociality.

This study examines how in-group bias affects altruistic sharing and second-party punishment in preschoolers and the role of theory of mind (ToM) in in-group bias. Preschoolers aged 4 to 7 years (N = 309; 160 girls) were asked to share resources with an in-group member and an out-group member (Dictator Game) and to reject or accept an unequal allocation proposed by an in-group member and an out-group member (Ultimatum Game). The results showed that preschoolers shared more resources with, and tolerated more unfair behaviors from, in-group members. ToM influenced the in-group bias in both altruistic sharing and second-party punishment. Notably, children's degree of in-group favoritism in altruistic sharing was positively related to the second-party punishment children imposed on out-group members. However, this pattern was found only among children who had acquired first-order ToM. This study reveals the developmental patterns of preschoolers' in-group bias in altruistic sharing and second-party punishment and the effects of ToM on in-group bias.

OBJECTIVES: To identify and describe potential societal and individual sources of support for orphan drug programs. METHODS: The Generalized Risk-Adjusted Cost-Effectiveness method shows that acute illness and disability severity increase individuals' willingness to pay for health gains. We develop a social welfare function (SWF) that incorporates individuals' own values, combined with politically or ethically determined weights. We introduce the concept of horizontal equity-that individuals in similar situations should be treated similarly-into the SWF. Finally, we introduce anonymous altruism into individuals' utility functions-the desire to help others, without knowing their identity. RESULTS: Combined with the empirical link between disease severity and rarity, the Generalized Risk-Adjusted Cost-Effectiveness method demonstrates heightened willingness to pay for health gains for people with rare diseases, leading rational individuals to support orphan drug programs, our first pillar of support. Adding horizontal equity to the SWF further increases societal support for orphan drug programs. Anonymous altruism, focusing most strongly on those in the most-dire circumstances, leads to altruistic support for those with severe disorders. Because innovators' economic incentives lead them to focus on larger markets, anonymous altruistic individuals will increasingly prefer public investments into rare diseases over time, as private markets systematically produce gains for common diseases. CONCLUSIONS: We identified 3 supporting pillars for orphan drug programs: (1) individuals' propensity to prefer treatments for severe diseases; (2) the preference for horizontal equity in our social welfare; (3) anonymous altruism, the desire to help strangers, coupled with market incentives that underserve strangers with rare diseases.
RESUMO
Mental health providers sometimes encounter patients who are exceptionally altruistic toward others and, at the same time, are willing to ignore their own needs and even significantly harm themselves to best achieve these ends for others. Traditionally, therapists have seen it to be their role to discern patients' negative symptoms, then seek to reduce them. This article reviews gains based on positive psychology that highlight the importance of therapists giving priority to supporting patients' strengths, particularly the sources of meaning they have in their lives. As is consistent with this view, it is suggested that therapists working with this group of self-harming, altruistic patients not only support their altruism, but particularly consider and remain cautious as to whether or not they should explore unconscious factors with the patient that might fuel their altruism. It is suggested that the discovery of such factors might be harmful because it could risk decreasing the degree to which these patients continue to show and personally value their altruism, thus potentially decreasing the meaning they derive from their altruism.
RESUMO
While humans are highly cooperative, they can also behave spitefully. Yet spite remains understudied. Spite can be normatively driven and while previous experiments have found some evidence that cooperation and punishment may spread via social learning, no experiments have considered the social transmission of spiteful behaviour. Here we present an online experiment where, following an opportunity to earn wealth, we asked participants to choose an action towards an anonymous partner across a full spectrum of social behaviour, from spite to altruism. In accordance with cultural evolutionary theory, participants were presented with social information that varied in source and content. Across six conditions, we informed participants that either the majority or the highest earner had chosen to behave spitefully, neutrally or altruistically. We found an overall tendency towards altruism, but at lower levels among those exposed to spite compared with altruism. We found no difference between social information that came from the majority or the highest earner. Exploratory analysis revealed that participants' earnings negatively correlated with altruistic behaviour. Our results contrast with previous literature that report high rates of spite in experimental samples and a greater propensity for individuals to copy successful individuals over the majority.
