Replicator-mutator dynamics with evolutionary public goods game-environmental feedbacks.

Feedback loops between strategies and the environment are commonly observed in socio-ecological, evolution-ecological, and psychology-economic systems. However, the impact of mutations in these feedback processes is often overlooked. This study proposes a novel model that integrates the public goods game with environmental feedback, considering the presence of mutations. In our model, the enhancement factor of the public goods game combines positive and negative incentives from the environment. By employing replicator-mutator (RM) equations, we provide an objective understanding of the system's evolutionary state, focusing on identifying conditions that foster cooperation and prevent the tragedy of the commons. Specifically, mutations play a crucial role in the RM dynamics, leading to the emergence of an oscillatory tragedy of the commons. By verifying the Hopf bifurcation condition, we establish the existence of a stable limit cycle, providing valuable insights into sustained oscillation strategies. Moreover, the feedback mechanism inherent in the public goods game model offers a fresh perspective on effectively addressing the classic dilemma of the tragedy of the commons.

Adjustments in Interprofessional Communication: A Focus Group Study in Psychiatric Outpatient Units.

Communication in healthcare extends beyond patient care, impacting the work environment and job satisfaction. Interprofessional communication is essential for fostering collaboration, but challenges arise from differences in training, roles, and hierarchies. The study aimed to explore psychiatric outpatient clinicians' experiences of interprofessional communication and their perceptions of how the communication intersects the organizational and social work environment of healthcare. Qualitative research involved focus group interviews with clinicians from five psychiatric outpatient units in Central Sweden, representing diverse professions. The authors analyzed semi-structured interview data thematically to uncover clinicians' perspectives on interprofessional communication. An overarching theme, "Adjustment of communication," with subthemes "Synchronized communication" and "Dislocated communication," emerged. Clinicians adapted communication strategies based on situations and needs, with synchronized communication promoting collaboration and dislocated communication hindering it. Communicating with each other was highly valued, as it contributed to a positive work environment. The study underscores the importance of an open, supportive environment that fosters trust, and respect among healthcare clinicians. Consistent with prior research, collaboration gaps underscore the urgent need to improve interprofessional communication.

Favoritism or bias? Cooperation and competition under different intergroup relationships: evidence from EEG hyperscanning.

Cooperation and competition are the most common forms of social interaction in various social relationships. Intergroup relationships have been posited to influence individuals' interpersonal interactions significantly. Using electroencephalography hyperscanning, this study aimed to establish whether intergroup relationships influence interpersonal cooperation and competition and the underlying neural mechanisms. According to the results, the in-group Coop-index is better than the out-group, whereas the out-group Comp-index is stronger than the in-group. The in-group functional connectivity between the frontal-central region and the right temporoparietal junction in the ß band was stronger in competition than cooperation. The out-group functional connectivity between the frontal-central region and the left temporoparietal junction in the α band was stronger in cooperation than competition. In both cooperation and competition, the in-group exhibited higher interbrain synchronization between the prefrontal cortex and parietal region in the θ band, as well as between the frontal-central region and frontal-central region in the α band, compared to the out-group. The intrabrain phase-locking value in both the α and ß bands can effectively predict performance in competition tasks. Interbrain phase-locking value in both the α and θ bands can be effectively predicted in a performance cooperation task. This study offers neuroscientific evidence for in-group favoritism and out-group bias at an interpersonal level.

Dynamics of collective cooperation under personalised strategy updates.

Collective cooperation is essential for many social and biological systems, yet understanding how it evolves remains a challenge. Previous investigations report that the ubiquitous heterogeneous individual connections hinder cooperation by assuming individuals update strategies at identical rates. Here we develop a general framework by allowing individuals to update strategies at personalised rates, and provide the precise mathematical condition under which universal cooperation is favoured. Combining analytical and numerical calculations on synthetic and empirical networks, we find that when individuals' update rates vary inversely with their number of connections, heterogeneous connections actually outperform homogeneous ones in promoting cooperation. This surprising property undercuts the conventional wisdom that heterogeneous structure is generally antagonistic to cooperation and, further helps develop an efficient algorithm OptUpRat to optimise collective cooperation by designing individuals' update rates in any population structure. Our findings provide a unifying framework to understand the interplay between structural heterogeneity, behavioural rhythms, and cooperation.

Social restructuring during harsh environmental conditions promotes cooperative behaviour in a songbird.

Cooperation may emerge from intrinsic factors such as social structure and extrinsic factors such as environmental conditions. Although these factors might reinforce or counteract each other, their interaction remains unexplored in animal populations. Studies on multilevel societies suggest a link between social structure, environmental conditions and individual investment in cooperative behaviours. These societies exhibit flexible social configurations, with stable groups that overlap and associate hierarchically. Structure can be seasonal, with upper-level units appearing only during specific seasons, and lower-level units persisting year-round. This offers an opportunity to investigate how cooperation relates to social structure and environmental conditions. Here, we study the seasonal multilevel society of superb fairy-wrens (Malurus cyaneus), observing individual responses to experimental playback of conspecific distress calls. Individuals engaged more in helping behaviour and less in aggressive/territorial song during the harsher non-breeding season compared to the breeding season. The increase in cooperation was greater for breeding group members than for members of the same community, the upper social unit, comprised of distinct breeding groups in association. Results suggest that the interaction between social structure and environmental conditions drives the seasonal switch in cooperation, supporting the hypothesis that multilevel societies can emerge to increase cooperation during harsh environmental conditions.

Integrating perspectives in developing mycorrhizal trait databases: a call for inclusive and collaborative continental efforts.

Global assessments of mycorrhizal symbiosis present large sampling gaps in rich biodiversity regions. Filling these gaps is necessary to build large-scale, unbiased mycorrhizal databases to obtain reliable analyses and prevent misleading generalizations. Underrepresented regions in mycorrhizal research are mainly in Africa, Asia, and South America. Despite the high biodiversity and endemism in these regions, many groups of organisms remain understudied, especially mycorrhizal fungi. In this Viewpoint, we emphasize the importance of inclusive and collaborative continental efforts in integrating perspectives for comprehensive trait database development and propose a conceptual framework that can help build large mycorrhizal databases in underrepresented regions. Based on the four Vs of big data (volume, variety, veracity, and velocity), we identify the main challenges of constructing a large mycorrhizal dataset and propose solutions for each challenge. We share our collaborative methodology, which involves employing open calls and working groups to engage all mycorrhizal researchers in the region to build a South American Mycorrhizal Database. By fostering interdisciplinary collaborations and embracing a continental-scale approach, we can create robust mycorrhizal trait databases that provide valuable insights into the evolution, ecology, and functioning of mycorrhizal associations, reducing the geographical biases that are so common in large-scale ecological studies.

Microbial Primer: Cooperation in bacteria.

The growth and success of many bacteria appear to rely on a stunning range of cooperative behaviours. But what is cooperation and how is it studied?

Value creation in a learning community: an interprofessional partnership between nursing home care, education and students.

OBJECTIVES: To assess the value created in a learning community - comprised of different professionals and nursing students - at a nursing home. METHODS: A case study approach was used. Data were collected between 2019 and 2021 through self-reports, observations and stories (interviews, diaries). RESULTS: The template analysis revealed nine transcending themes, six associated with preexisting value-creation cycles (expected, immediate, potential, applied, realized and transformative value) and three other relevant themes: contextual, factors and value-creation initiators. CONCLUSIONS: A nursing home learning community comprised of diverse professionals in partnership with nursing students shows a variety of value creation and seems to potentially leverage interprofessional and lifelong learning activities, on top of formal nursing education. It is recommended to integrate the value-creation cycles into the processes of learning communities to promote collective decision-making. Research on both the final level of students involved and having residents participate in the learning community would be worthwhile.

Lessons from Two Latino Communities Working with Academic Partners to Increase Access to COVID-19 Testing.

OBJECTIVE: We sought to examine the experiences of community partners in a community-academic partnership to promote COVID-19 testing in two majority Latino communities. METHODS: We conducted semistructured, in-depth interviews in English and Spanish with community-based organization leaders and community health workers/promotoras (n = 10) from June to July 2021. Interviews focused on identifying partner roles in planning and testing implementation and evaluating communication among partners. Interviews were transcribed and analyzed in ATLAS.ti version 8.4.5. Analyses involved deductive and inductive approaches to identify key themes. RESULTS: Participants described both strengths and challenges to the collaborative approach within each of three core themes: building relationships in the time of COVID-19; uplifting existing community leadership; and commitment of the academic partners and community-based organizations to conduct partnership activities in Spanish. CONCLUSION: Community-academic partnerships that invest in strong relationships, community leadership, and a commitment to the community's preferred language offer a promising approach to addressing COVID-19 testing barriers. Findings provide direction for future research on how community members and academic partners can come together to inform strategies to continue addressing the COVID-19 pandemic.

A Model of Community Health Worker Integration into Schools: Community-based Participatory Research in Action.

BACKGROUND: Schools are rich sites for collaborations between health and educational sectors. OBJECTIVES: To identify lessons learned from formation of a community-academic partnership and application of community-based participatory research (CBPR) to develop a model that integrates community health workers into schools. METHODS: Individuals from an academic medical center, a large public school district, and a community-based research institute applied CBPR principles to reimagine schools as a place for improving the health of children. LESSONS LEARNED: Three lessons emerged. Leveraging each team member's expertise centered the partnership on community strengths, co-learning, and stakeholder engagement. Adherence to CBPR's principles of power sharing and equity helped navigate the challenges of collaboration between large institutions. Early focus on sustainability helped address unexpected issues, build capacity, and boost advocacy. CONCLUSIONS: This partnership demonstrates how CBPR fosters conditions in which equitable partnerships between research institutions and public schools can thrive to promote childhood health.

Discipline and punishment in panoptical public goods games.

In Public Goods Games (PGG), the temptation to free-ride on others' contributions poses a significant threat to the sustainability of cooperative societies. Therefore, societies strive to mitigate this through incentive systems, employing rewards and punishments to foster cooperative behavior. Thus, peer punishment, in which cooperators sanction defectors, as well as pool punishment, where a centralized punishment institution executes the punishment, is deeply analyzed in previous works. Although the literature indicates that these methods may enhance cooperation on social dilemmas under particular contexts, there are still open questions, for instance, the structural connection between graduated punishment and the monitoring of public goods games. Our investigation proposes a compulsory PGG framework under Panoptical surveillance. Inspired by Foucault's theories on disciplinary mechanisms and biopower, we present a novel mathematical model that scrutinizes the balance between the severity and scope of punishment to catalyze cooperative behavior. By integrating perspectives from evolutionary game theory and Foucault's theories of power and discipline, this research uncovers the theoretical foundations of mathematical frameworks involved in punishment and discipline structures. We show that well-calibrated punishment and discipline schemes, leveraging the panoptical effect for universal oversight, can effectively mitigate the free-rider dilemma, fostering enhanced cooperation. This interdisciplinary approach not only elucidates the dynamics of cooperation in societal constructs but also underscores the importance of integrating diverse methodologies to address the complexities of fostering cooperative evolution.

Putting theory to the test: An integrated computational/experimental chemostat model of the tragedy of the commons.

Cooperation via shared public goods is ubiquitous in nature, however, noncontributing social cheaters can exploit the public goods provided by cooperating individuals to gain a fitness advantage. Theory predicts that this dynamic can cause a Tragedy of the Commons, and in particular, a 'Collapsing' Tragedy defined as the extinction of the entire population if the public good is essential. However, there is little empirical evidence of the Collapsing Tragedy in evolutionary biology. Here, we experimentally demonstrate this outcome in a microbial model system, the public good-producing bacterium Pseudomonas aeruginosa grown in a continuous-culture chemostat. In a growth medium that requires extracellular protein digestion, we find that P. aeruginosa populations maintain a high density when entirely composed of cooperating, protease-producing cells but completely collapse when non-producing cheater cells are introduced. We formulate a mechanistic mathematical model that recapitulates experimental observations and suggests key parameters, such as the dilution rate and the cost of public good production, that define the stability of cooperative behavior. We combine model prediction with experimental validation to explain striking differences in the long-term cheater trajectories of replicate cocultures through mutational events that increase cheater fitness. Taken together, our integrated empirical and theoretical approach validates and parametrizes the Collapsing Tragedy in a microbial population, and provides a quantitative, mechanistic framework for generating testable predictions of social behavior.

Social bond dynamics and the evolution of helping.

Empiricists often struggle to apply game theory models to real-life cases of animal cooperation. One reason is that many examples of cooperation occur in stable groups, where individuals form social bonds that influence exchanges of help in ways that are not well described by previous models, including the extent of reciprocity and how relationships are initiated. We present a game theory model exploring the conditions under which social bonds between group members promote cooperation. In the model, bonds build up from exchanges of help in a similar way as the strength of association increases in learning, as in the Rescorla-Wagner rule. The bonds in turn affect partner choice and influence helping amounts. The model has a mechanism of reciprocity for bonded pairs, which can evolve toward either loose or strict reciprocation. Several aspects of the model are inspired by observations of food sharing in vampire bats. We find that small social neighborhoods are required for the evolutionary stability of helping, either as small group sizes, or if bonded members of larger groups can form temporary (daily) smaller groupings. The costs of helping need to be fairly low, while the benefits can be substantial. The form of reciprocity that evolves is neither immediate nor very strict. Individuals in need request help based on bond strength, but there is also an evolved preference for initiating bonds with new group members. In contrast, if different groups come into temporary contact, the evolved tendency is to avoid forming bonds between groups.

Care complexity, perceptions of complexity and preferences for interprofessional collaboration: an analysis of relationships and social networks in paediatrics.

BACKGROUND: In the context of increasingly intricate healthcare systems, professionals are compelled to collaborate within dynamically changing interprofessional teams. Moreover, they must adapt these collaborative processes to effectively and efficiently manage the evolving complexity of care needs. It remains unclear how professionals determine care complexity and relate this complexity to their preferences for interprofessional collaboration (IPC). This study investigated the relationships between care complexity, professionals' perceived complexity and IPC preferences, and examined the variation in individual and team characteristics of IPC-practices across different levels of complexity in paediatric care. METHODS: In an online questionnaire, 123 healthcare professionals working at an academic tertiary children's hospital scored their perceptions of complexity and preferences for IPC. They also selected family and various professions as members of the interprofessional (IP-) team based on thirteen patient cases. We employed conjoint analysis to systematically model the complexity of case descriptions across the five domains of the International Classification of Functioning, Disability and Health (ICF). Additionally, we applied social network analysis to identify important professions, crucial connectors and influential professions in the IP-team, and to describe the cohesiveness of IP-teams. RESULTS: Modelled case complexity, professionals' perceived complexity and IPC preferences were positively associated. We found large inter-individual variations in the degree of these associations. Social network analysis revealed that the importance and influence of professions was more equally distributed when case complexity increased. Depending on the context and complexity of the case, different professions (e.g. medical doctors, social professionals, extramural professionals) were considered to be more crucial connectors within the IP-team. Furthermore, team cohesion was positively associated with modelled and perceived care complexity. CONCLUSIONS: In conclusion, our study contributes to the existing knowledge by integrating task-specific insights and broadening the use of conjoint and social network analysis in the context of IPC. The findings substantiate the contingency theory that relates characteristics of IPC to care complexity, offering quantified insights into how IP-teams adapt to situational needs. This understanding of relationships and variations within IPC holds crucial implications for designing targeted interventions in both clinical and health profession education contexts. Consequently, it contributes to advancements in healthcare systems.

Top 10 research priorities for digital technology for adolescents and young persons with inflammatory bowel disease: Results of a James Lind Alliance Priority Setting Partnership.

OBJECTIVES: Priority Setting Partnerships (PSP's) using the James Lind Alliance (JLA) methodology, bring together health professionals, patients and parents/carers to identify and prioritise unanswered questions that can be addressed by future research projects. To identify and prioritise the top 10 unanswered research priorities in digital technology for adolescents and young people (AYP) with inflammatory bowel disease (IBD). METHODS: A steering group (SG) consisting of AYP with IBD, their parents/carers, representatives from two charities (Crohn's & Colitis UK, Crohn's in Childhood Research Association), patient information forum and paediatric and adult and primary care healthcare professionals was established in 2021. The SG agreed the protocol, and scope of the PSP and oversaw all aspects. SG meetings were chaired by a JLA advisor and followed the established JLA methodology. RESULTS: The initial survey generated 414 in-scope questions from 156 respondents, thematically categorised into 10 themes and consolidated into 92 summary questions by the SG. A comprehensive literature review followed by SG deliberation narrowed the unanswered summary questions to 45, for the interim prioritising survey. One hundred and two respondents ranked their top 10 research questions. Outputs generated top 18 research priorities presented at a final virtual prioritisation workshop, facilitated by JLA advisors and attended by key stakeholders, ranked into top 10 research priorities. DISCUSSION: The top 10 research priorities will encourage researchers to undertake research that addresses these areas of unmet need for AYP living with IBD, their parents/carers and their healthcare professionals, thereby facilitating improved patient care.

Personality heterophily and friendship as drivers for successful cooperation.

Cooperation is widespread and arguably a pivotal evolutionary force in maintaining animal societies. Yet, proximately, what underlying motivators drive individuals to cooperate remains relatively unclear. Since 'free-riders' can exploit the benefits by cheating, selecting the right partner is paramount. Such decision rules need not be based on complex calculations and can be driven by cognitively less-demanding mechanisms, like social relationships (e.g. kinship, non-kin friendships, dyadic tolerance), social status (e.g. dominance hierarchies) and personalities (social and non-social traits); however, holistic evidence related to those mechanisms is scarce. Using the classical 'loose-string paradigm', we tested cooperative tendencies of a hierarchical primate, the long-tailed macaque (Macaca fascicularis). We studied three groups (n = 21) in their social settings, allowing partner choice. We supplemented cooperation with observational and experimental data on social relationships, dominance hierarchies and personality. Friendship and dissimilarities in non-social 'exploration' and 'activity-sociability' personality traits predicted the likelihood of cooperative dyad formation. Furthermore, the magnitude of cooperative success was positively associated with friendship, low rank-distance and dissimilarity in the activity-sociability trait. Kinship did not affect cooperation. While some findings align with prior studies, the evidence of (non-social) personality heterophily promoting cooperation may deepen our understanding of the proximate mechanisms and, broadly, the evolution of cooperation.

Interprofessional collaboration in the cardiovascular management of Marfan syndrome: A qualitative study based on interviews with professionals.

BACKGROUND AND AIM: Patients with Marfan syndrome, who present with a variety of symptoms and complex psychosocial problems, require interprofessional collaboration in their care. However, it is unclear how health care providers contribute to interprofessional collaboration for these patients. The purpose of this study was to determine the characteristics of interprofessional collaboration for patients with Marfan syndrome in the cardiovascular field. METHODS: Semi-structured interviews were conducted with health care specialists (5 physicians, 2 nurses, and 3 certified genetic counselors) were analyzed qualitatively. RESULTS: Based on the medical collaboration for the management of cardiovascular complications in patients and their relatives, interprofessional collaboration was identified, such as collaboration and cooperation between physicians and certified genetic counselors, and nursing practice to facilitate interprofessional collaboration. In addition, issues such as difficulties in dealing with and coordinating medical care for noncardiovascular complications, lack of specialist physicians, and lack of opportunities to collaborate with nurses were identified. CONCLUSIONS: Effective interprofessional collaboration requires the acquisition of Marfan syndrome and genetic knowledge by healthcare providers and the development of a healthcare delivery system based on departments that can provide leadership. In addition, the assignment of nurses to work across organizational boundaries and effective collaboration between genetic counselors and nurses should be considered.

Harsh environmental conditions promote cooperative behavior in an epiphytic fern.

Harsh, unpredictable environments are known to favor cooperative groups in animals. Whether plants exhibit similar relationships is unknown. Staghorn ferns (Platycerium bifurcatum, Polypodiaceae) are epiphytes that form cooperative groups which build communal water and nutrient 'nests' at the tops of trees, a habitat characterized by water and nutrient stress. We conducted field observations to test whether staghorn ferns continue to live in large, reproductively active groups after they become dislodged from the canopy and fall to the forest floor, where they are less limited by water and nutrient deprivation. To rule out the potentially confounding effects of light limitation on the forest floor, we also conducted a multi-year glasshouse experiment where we transplanted individual plants into soil and onto vertically oriented boards under standardized light conditions. Results from field observations showed that dislodged colonies formed smaller groups that reproduced less than epiphytic colonies. Results from the glasshouse experiment showed that even when growing in full sun, terrestrial individuals tended to remain solitary, while epiphytic individuals tended to recruit new individuals into colonies. Results also showed that plants growing in potting soil and exposed to full sunlight sporulated more heavily than plants growing epiphytically. However, localities that are characterized by both elevated soil and light resources are generally not available to staghorn ferns in the wild, perhaps with the exception of large, epiphytic colonies with well-developed nests at the top of tree canopies. Overall results indicate that the harsh environmental conditions at the tops of trees trigger the formation of colonies in staghorn ferns, similarly to group living animals.
