The roles of gene duplications in the dynamics of evolutionary conflicts.

Evolutionary conflicts occur when there is antagonistic selection between different individuals of the same or different species, life stages or between levels of biological organization. Remarkably, conflicts can occur within species or within genomes. In the dynamics of evolutionary conflicts, gene duplications can play a major role because they can bring very specific changes to the genome: changes in protein dose, the generation of novel paralogues with different functions or expression patterns or the evolution of small antisense RNAs. As we describe here, by having those effects, gene duplication might spark evolutionary conflict or fuel arms race dynamics that takes place during conflicts. Interestingly, gene duplication can also contribute to the resolution of a within-locus evolutionary conflict by partitioning the functions of the gene that is under an evolutionary trade-off. In this review, we focus on intraspecific conflicts, including sexual conflict and illustrate the various roles of gene duplications with a compilation of examples. These examples reveal the level of complexity and the differences in the patterns of gene duplications within genomes under different conflicts. These examples also reveal the gene ontologies involved in conflict and the genomic location of the elements of the conflict. The examples provide a blueprint for the direct study of these conflicts or the exploration of the presence of similar conflicts in other lineages.

A sleepless night disrupts the resolution of emotional conflicts: Behavioural and neural evidence.

The present study aims to investigate the influence of 24-hr sleep deprivation on implicit emotion regulation using the emotional conflict task. Twenty-five healthy young adults completed a repeated-measures study protocol involving a night of at-home normal sleep control and a night of in-laboratory sleep deprivation. Prior to the experimental session, all participants wore an actigraph watch and completed the sleep diary. Following each condition, participants performed an emotional conflict task with electroencephalographic recordings. Emotional faces (fearful or happy) overlaid with words ("fear" or "happy") were used as stimuli creating congruent or incongruent trials, and participants were instructed to indicate whether the facial expression was happy or fearful. We measured the accuracy and reaction time on the emotional conflict task, as well as the mean amplitude of the P300 component of the event-related potential at CPz. At the behavioural level, sleep-deprived participants showed reduced alertness with overall longer reaction times and higher error rates. In addition, participants in the sleep deprivation condition made more errors when the current trial followed congruent trials compared with when it followed incongruent trials. At the neural level, P300 amplitude evoked under the sleep-deprived condition was significantly more positive compared with the normal sleep condition, and this effect interacted with previous-trial and current-trial congruency conditions, suggesting that participants used more attentional resources to resolve emotional conflicts when sleep deprived. Our study provided pioneering data demonstrating that sleep deprivation may impair the regulation of emotional processing in the absence of explicit instruction among emerging adults.

Embracing Complexity: A Review of Negotiation Research.

In this review, we identify emerging trends in negotiation scholarship that embrace complexity, finding moderators of effects that were initially described as monolithic, examining the nuances of social interaction, and studying negotiation as it occurs in the real world. We also identify areas in which research is lacking and call for scholarship that offers practical advice. All told, the existing research highlights negotiation as an exciting context for examining human behavior, characterized by features such as strong emotions, an intriguing blend of cooperation and competition, the presence of fundamental issues such as power and group identity, and outcomes that deeply affect the trajectory of people's personal and professional lives.

An Automobile's Tail Lights: Sacrificing Safety for Playful Design?

OBJECTIVE: The counterintuitive "Union Jack"-inspired turn signals on versions of BMW's Mini vehicles was investigated to reveal potential impacts on human performance. BACKGROUND: When some Mini drivers indicate a change in direction, they do so with an oppositely oriented arrow. This conflict, between the task-irrelevant spatial shape and task-relevant location of the signal, mimics a "converse" spatial-Stroop effect that, in combination with the ubiquitous use of arrows on road signs, may be confusing. METHOD: Participants (n = 30) responded-via right and left keypresses-to the directions of road signs and turn signals in both pure and mixed blocks. Reaction times and accuracies were recorded to determine performance in each condition (compatible, neutral, incompatible). RESULTS: Performance suffered when the location and direction of the stimuli did not correspond. When responding to turn signals the cost to performance was especially salient in mixed blocks. Thus, when driving on roads where the meanings of arrows on road signs is important, turn signals pointing in a direction opposite from the directional intention indicated by the signals' location are likely to be confusing. CONCLUSION: The design of some Mini's "Union Jack" style taillights opposes well-established principles of cognitive functioning, caused confusion in our laboratory study and therefore may be a safety hazard-a possibility that ought to be explored in more realistic (e.g., driving simulator) situations. APPLICATION: BMW designers should consider universally adopting the neutral, "horizontal line," illumination style that is currently available in the aftermarket.

Fostering collaborative practice through interprofessional simulation for occupational therapy, physiotherapy, dietetics, and nursing students.

Literature regarding simulation for learning interprofessional collaborative practice (IPCP) indicates a need to include a range of health professions and to focus on students' development of team communication and conflict resolution skills in day-to-day healthcare delivery. This study evaluated the impact of interprofessional simulation for occupational therapy, physiotherapy, dietetics, and nursing students on interprofessional collaboration competencies, specifically collaborative communication and conflict resolution during day-to-day interactions, and their intention for IPCP during placement. A series of simulations featuring the potential for interprofessional conflict and involving explicit coaching on communication and conflict resolution were conducted. A single cohort pre-test post-test design included the Students' Perceptions of Interprofessional Clinical Education Revised (SPICE-R), the Interprofessional Collaborative Competencies Attainment Survey (ICCAS), and an open response survey question on future intended practice. A total of 237 students participated in the simulation experience. Overall scores and scores on all IPCP competencies in the ICASS (n = 193) and SPICE-R (n = 226) improved for all professions post-simulation. The mean score of the ICCAS increased for 98% of the respondents and similarly the mean score of the SPICE-R increased for 71% of the respondents. Open-ended responses indicated students' intentions to pursue self-leadership in IPCP. Students who participated in an interprofessional simulation reported perceived improvements in IPCP competencies and were encouraged to initiate IPCP when on placement in the practice setting.

Impact of emotional intelligence in resolving clinical conflicts among postgraduate residents of surgery.

Background & Objective: Emotional intelligence (EI) can become a vital tool for resolving clinical conflicts (CC) in surgery. The postgraduate residents focus on the technical skills and undermine the soft skills required for their better training. Our aim was to determine the EI of postgraduate resident (PGR) years one & two in General and Orthopedic Surgery. The CC in their workplace and how they use their EI to resolve these conflicts. Methods: This mixed-method study was conducted from March 10, 2019 to May 28, 2020 at Departments of General and Orthopedic Surgery, Mayo Hospital, Lahore. The study was conducted in two phases 1 & 2. In Phase-1, one hundred PGR years one & two were administered the Mayor-Salovey-Caruso Emotional Intelligence test (MSCEIT) to measure EI. In phase-2, semi-structured in-depth interviews of 10 PGRs five with high and five with low EI were conducted to determine the CC and use of EI to resolve the CC at the workplace. A thematic analysis was done. Results: Out of 100 PGR, the mean EI score was 46.25±14.8 with a maximum score of 75.4, and a minimum score of 18.16 (p-value =0.775). Ninety-one (91%) have not improving EI, and 09 (09%) have considered developing EI. Five themes in four settings, including emergency, ward, elective operation theatre, and outpatient department (OPD) were determined. The emerged themes for the CC were nepotism, gender biases, burnout, lack of professionalism, and toxic culture. The following were CC management strategies: self-study, deceit, gender affinity, performing attention-attaining work, aggrieved reaction and being disgruntled when alone. Conclusion: None of the PGR was emotionally intelligent in overall grades, as well as a particular aspect of MSCEIT.

Third-party intervention and post-conflict behaviour in agonistic encounters of pigs (Sus scrofa).

BACKGROUND: Third-party interference in agonistic contests entails a deliberate intervention in an ongoing fight by a bystanding individual (third party) and may be followed by post-conflict social behaviour to provide support to a specific individual. The mechanisms behind third-party intervention are, however, still largely understudied. The aim of this study was to investigate third-party interference, with the predictions that (1) the interferer derives benefits from its action by winning a fight, (2) that patterns of intervention depend on familiarity, (3) that dyadic fights last longer than triadic fights, and (4) that interferers engage in non-agonistic social behaviours afterwards. Pre-pubertal pigs (Sus scrofa) (n = 384) were grouped with one familiar and four unfamiliar conspecifics (all non-kin) to elicit contests for dominance rank. Third-party interference was analysed for the first 30 min after grouping, along with the behaviour (nosing or aggression), contest duration, contest outcome, and interferer behaviour after the fight (post-conflict social behaviour). RESULTS: Three types of interference were observed: non-agonistic involvement (nose contact) by the interferer in a dyadic fight; a triadic fight with each of three contestants fighting one opponent at a time; and triadic fights with two opponents jointly attacking the third one (two-against-one fights). The likelihood of a third-party intervention to occur did not depend on the presence of a familiar animal in the fight. However, once intervention was triggered, interferers attacked unfamiliar fight initiators more than familiar ones. Two-against-one fights lasted longer than other triadic fights and occurred more often when both initial contestants were females. Results of 110 triadic fights (out of 585 fights in total) revealed that interferers were more likely to win compared to the initial opponents at equal body weight. The most common post-conflict behaviour displayed by the interferer was agonistic behaviour towards another group member, independently of familiarity. CONCLUSIONS: The general lack of discrimination for familiarity suggests interference is not driven by support to familiar individuals in pigs. The results show that intervening in an ongoing fight gives the interferer a high chance of contest success and may be a strategy that is beneficial to the interferer to increase its dominance status.

Examining how study teams manage different viewpoints and priorities in patient-centered outcomes research: Results of an embedded multiple case study.

INTRODUCTION: Limited evidence exists about which patient and stakeholder engagement practices support or hinder study teams as they negotiate different viewpoints in decisions about the design and conduct of patient-centered outcomes research. METHODS: We applied a multiple-embedded descriptive case study design for six studies funded by the Patient-Centered Outcomes Research Institute (PCORI). We interviewed 32 researchers and stakeholder partners, including patients, caregivers and clinicians, and reviewed documents related to each study (e.g., publications, and progress reports submitted to PCORI). FINDINGS: Overall, researchers reported that incorporating different viewpoints was a strength or opportunity to learn rather than something to be avoided or dreaded. Across cases, different viewpoints and priorities, often related to ethical or pragmatic considerations, emerged between researchers and stakeholders, between stakeholder groups (e.g., patients and clinicians) or within groups (e.g., amongst researchers). Examples of navigating different viewpoints arose across study phases. The length of time to resolve issues depended on how strongly people disagreed and the perceived importance or impact of decisions on the study. All cases used collaborative decision-making approaches, often described as consensus, throughout the study. Interviewees described consensus as using negotiation, compromise or working towards an agreeable decision. To encourage consensus, cases actively facilitated group discussions with an openness to diverse opinions, remained flexible and open to trying new things, referenced a ground rule or common goal and delegated decisions to partners or smaller workgroups. When viewpoints were not easily resolved, cases used different approaches to reach final decisions while maintaining relationships with partners, such as elevating decisions to leadership or agreeing to test out an approach. No one engagement structure (e.g., advisory group, coinvestigator) stood out as better able to manage different viewpoints. Teams adjusted engagement structures and behaviours to facilitate an overall culture of inclusion and respect. Partners acknowledged the intentional efforts of researchers to incorporate their perspectives, navigate challenges and communicate the value of partner input. CONCLUSION: By using collaborative decision-making in the early stages and throughout the study, researchers built trust with partners so that when decisions were difficult to resolve, partners still felt listened to and that their input mattered. PATIENT OR PUBLIC CONTRIBUTION: Members of the PCORI Patient Engagement Advisory Panel in 2019-2020 provided input into the design of the study, including the research questions and approaches to data collection and analysis.

How do family caregivers of older adults cope with relationship strain?

OBJECTIVE: Studies of families' experiences with caregiving to older adults most often focus on overall burden and stress. Yet, caregiving is also a type of relationship, and the onset of caregiving can contribute to relationship strain between care partners. Despite implications for both care partners, little is known about how caregivers cope with caregiving relationship strain. METHODS: The authors conducted nine focus groups and 8 interviews with a purposeful sample of racially and ethnically diverse family caregivers in Los Angeles. Conventional content analysis was applied to transcripts to identify how caregivers cope with relationship strain. RESULTS: Analyses revealed four overall coping approaches to manage relationship strain: (1) Self-Care; (2) Adapting Behaviors, (3) Adapting Feelings and Cognitions, and (4) Help and Support. Selected strategies likely vary by care recipient condition. For example, caregivers for persons living with dementia emphasize adapting their own behaviors and feelings, rather than trying to change their loved one's behaviors. CONCLUSIONS: Findings suggest that caregivers cope with relationship strain using both interpersonal tension and care management strategies. We also identified possible variations by care recipient condition and caregiver race and ethnicity. These results suggest a need for interventions focused on caregiver coping should also be tested for effects on relationship strain.

Conflict resolution styles and skills and variation among medical students.

BACKGROUND: Conflict is inevitable on healthcare teams, yet few professional school curricula teach or assess conflict resolution skills. Little is known about the variation in conflict resolution styles across medical students and how these styles might impact conflict resolution skills. METHODS: This is a prospective, single blinded, group randomized quasi experimental trial to assess the impact of knowing one's own conflict resolution style on conflict resolution skills in a simulated encounter. Graduating medical students completed a mandatory conflict resolution session with standardized patients acting as nurses during a transition to residency course. Coaches reviewed videotapes of the simulation, focusing on students' skills with negotiation and emotional intelligence. Retrospectively, we assessed the impact of the students knowing their conflict resolution style prior to simulation, student gender, race, and intended field of practice on conflict resolution skills as judged by coaches. RESULTS: One hundred and eight students completed the simulated conflict session. Sixty-seven students completed the TKI before the simulated patient (SP) encounter and 41 after. The most common conflict resolution style was accommodating (n = 40). Knowing one's conflict resolution style in advance of the simulation and one's identified race/ethnicity did not impact skill as assessed by faculty coaches. Students pursuing diagnosis-based specialties had higher negotiation (p = 0.04) and emotional quotient (p = 0.006) scores than those pursuing procedural specialties. Females had higher emotional quotient scores (p = 0.02). CONCLUSIONS: Conflict resolution styles vary among medical students. Male gender and future practice in a procedural specialty impacted conflict resolution skills but knowing conflict resolution style did not.

Examining the choice of land conflict resolution mechanisms: The case between the harshin and yocaale woredas of the Somali region of Ethiopia.

This study examines the choice of conflict resolution mechanisms between Yocaale and Harshin pastoral communities in the Somali regional state of Ethiopia. Between 1984 and 2014, the area experienced several land use changes, leading to a decrease in the vegetation cover of grass, shrubs, and woodlands. Furthermore, from 2000 to 2005, ten new urban areas have been established. This changed the area's rangeland caring capacity, which, in turn, triggered competition over dwindling resources. Evidence also indicates that climate change has exacerbated the competition for scarce resources in this area. In response, the pastoralist communities began practicing crop cultivation, petty trading, land enclosure, and charcoal production, particularly in the Harshin woreda (district). The 2011 regional administrative restructuring decision created new administrative units and sandwiched the Yocaale pastoralist community between the Harshin and Aware woredas. The decision to establish a new woreda, coupled with the area enclosure and land privatization, impeded the opportunistic movement of the Harshin and Yocaale's pastoralists and became a source of competition for communal land resources. This study used a mixed methods approach of qualitative and quantitative analyses and deployed a binary logit model to identify the two woredas' conflict resolution preferences. The findings indicate that the land disputes between the two woredas, which are mainly on administrative borders conflict, is less likely to be taken to customary institutions to resolve. Instead, they opt to formal court system. In conclusion, even though the findings of this work highlight the customary institution's vital role in preventing and resolving inter-ethnic conflicts, administrative border-related land conflicts are less likely to be taken to customary institutions, as they require political decision-making in multiple contested clan areas, such as Yocaale and Harshin. Therefore, in addition to particular corrective political measures, the results of this study point to the need for enhancing the level of integration and cooperation between the two communities and finding a middle way to enhance community dialogue.

Applying the AHP to Conflict Resolution: A Russia-NATO Case Study.

In this paper, we apply the Analytic Hierarchy Process approach to conflict resolution in the context of the Russia-Ukraine conflict. We build models that illustrate the evaluation criteria, strategic and sub-criteria, and concessions for each party in this negotiation. Ratings are used to evaluate the degree to which concessions contribute or take away from successful resolution of the conflict. Afterwards, gain ratios are built to determine the benefit-cost scores so that concessions may be traded that result in equitable solutions. The approach presented here demonstrates for the first time why all concessions that parties to a conflict may offer might not trade all at once. A Max-Min optimization approach is used to maximize the gain to both parties of the conflict while minimizing the disparity in gain between the two.

A classification framework for interspecific trade-offs in aquatic ecology.

In some cases, wildlife management objectives directed at multiple species can conflict with one another, creating species trade-offs. For managers to effectively identify trade-offs and avoid their undesirable outcomes, they must understand the agents involved and their corresponding interactions. A literature review of interspecific trade-offs within freshwater and marine ecosystems was conducted to illustrate the scope of potential interspecific trade-offs that may occur. We identified common pitfalls that lead to failed recognition of interspecific trade-offs, including, single-species management and limited consideration of the spatial and temporal scale of ecosystems and their management regimes. We devised a classification framework of common interspecific trade-offs within aquatic systems. The classification can help managers determine whether the conflict is species based through direct relationships (i.e., predator-prey, competition, other antagonistic relationships) or indirect relationships involving intermediate species (i.e., conflict-generating species) or whether the conflict is driven by opposing management objectives for species that would otherwise not interact (i.e., nontarget management effects). Once the nature and scope of trade-offs are understood, existing decision-making tools, such as structured decision-making and real-options analysis, can be incorporated to improve the management of aquatic ecosystems. Article Impact Statement: A synthesis of interspecific trade-offs in aquatic ecosystems supports their identification and resolution.

Un Marco de Clasificación para Compensaciones Interespecíficas en Ecología Acuática Resumen En algunos casos, los objetivos del manejo de fauna dirigidos a muchas especies pueden entrar en conflicto entre sí creando compensaciones entre las especies. Para que los manejadores identifiquen efectivamente estas compensaciones y eviten sus resultados no deseados, deben entender a los agentes involucrados y sus interacciones correspondientes. Se realizó una revisión literaria de las compensaciones interespecíficas dentro de los ecosistemas marinos y de agua dulce para ilustrar el alcance de las compensaciones interespecíficas que pueden ocurrir. Identificamos dificultades comunes que llevan al reconocimiento fallido de las compensaciones interespecíficas, incluyendo el manejo de una sola especie y sus regímenes de manejo. Diseñamos un marco de clasificación de compensaciones interespecíficas comunes dentro de los ecosistemas acuáticos. La clasificación puede ayudar a los manejadores a determinar si el conflicto está basado en las especies por sus relaciones directas (es decir, depredador-presa, competencia, otras relaciones antagonistas) o por relaciones indirectas que involucran a otras especies (es decir, efectos del manejo de especies que no son el objetivo). Una vez que se entiende la naturaleza y el alcance de las compensaciones, las herramientas de toma de decisión existentes, como la toma estructurada de decisiones y el análisis de opciones reales, pueden incorporarse para mejorar el manejo de los ecosistemas acuáticos.

Receptiveness to Opposing Views: Conceptualization and Integrative Review.

The present article reviews a growing body of research on receptiveness to opposing views-the willingness to access, consider, and evaluate contradictory opinions in a relatively impartial manner. First, we describe the construct of receptiveness and consider how it can be measured and studied at the individual level. Next, we extend our theorizing to the interpersonal level, arguing that receptiveness in the course of any given interaction is mutually constituted by the dispositional tendencies and observable behaviors of the parties involved. We advance the argument that receptiveness should be conceptualized and studied as an interpersonal construct that emerges dynamically over the course of an interaction and is powerfully influenced by counterpart behavior. This interpersonal conceptualization of receptiveness has important implications for intervention design and raises a suite of novel research questions.

Comparing the affective and social effects of positive reappraisal and minimising reappraisal.

Negative interpersonal events, such as close relationship conflicts, can threaten one's affective and social well-being. To improve affect and to maintain valuable relationships, individuals could select different reappraisal tactics. One could use positive reappraisal to find potential benefits of the event (e.g. "This conflict helps our relationship grow."), or use minimising reappraisal to decrease the perceived impact of event (e.g. "This is no big deal."). These two tactics target distinct appraisal dimensions: valence versus significance. We investigated whether these two reappraisals would show similar or different profiles of affective and social effects in the context of close relationship conflicts. Study 1 was based on a sample of 90 Chinese younger adults. Study 2 was based on a sample of 237 American adults (156 MTurk workers and 81 undergraduates combined). Across two studies, both reappraisals effectively improved affect in response to a recalled conflict. Minimising reappraisal group showed significantly increased affect and relationship satisfaction (Study 1&2), but decreased conflict resolution motivation (Study 2) across time. Positive reappraisal group, on the other hand, showed less pronounced increases in positive affect but increased conflict resolution self-efficacy across time (Study 1&2). We discuss these findings by highlighting within-reappraisal variation and potential trade-offs in pursuing affective and social regulation goals.

Introducing conflict resolution and negotiation training into a biomedical sciences graduate curriculum.

BACKGROUND: Analysis of the biomedical workforce and graduate education have produced recommendations for modifications of pre-doctoral training to broadly prepare trainees for wider ranging scientific careers. Development of training in professional skills is widely recommended, but details of implementation are not widely available. In alignment with these recommendations, we have incorporated professional skills training into the biomedical science graduate curriculum at West Virginia University. An important component of the training is developing conflict resolution and negotiation skills. This training will provide useful skills for academic careers, non-academic careers and life situations outside of the workplace. Conflict resolution/negotiation skills are also relevant in managing issues in diversity, equity and inclusivity. We report our experience in developing this component of the training program, provide an overview of the approach to delivery and practice of skills, and provide an analysis of the reception and effectiveness of the training. METHODS: Evaluation of effectiveness of training used the principals of the Kirkpatrick Four Level Model of Evaluation. At the end of the course, students completed a questionnaire about their perceptions of training and were asked how they would respond to different scenarios requiring conflict resolution/negotiation skills. Several months later, students were surveyed to determine if they used some of these skills and/or witnessed situations where these skills would be useful. RESULTS: We report our experience in developing conflict resolution/negotiation training in our graduate curriculum, provide an overview of the approach to delivery and practice of skills, and provide an analysis of the reception and effectiveness of the training. The results suggest this training meets a need and is effective. Importantly, these materials provide a template for others wishing to implement similar training in their curricula. CONCLUSIONS: Conflict resolution and negotiation training meets a need in graduate education. A mixed approach using didactic and interactive components spaced out over time appears to be an effective method of training.

Reasons and resolution approaches of environmental conflict in grassland areas: An empirical study in contemporary northern China.

Environmental conflicts frequently occur in grassland areas, which form the largest terrestrial ecosystem in China. Grassland conflict not only seriously affects environmental and public governance, but also threatens social stability and economic development. Based on a field study using surveys and interviews with 5,490 respondents and a case study of 30 cases in northern China, this paper explores the reasons for and resolution approaches to environmental conflict in grassland areas and identified three key findings. First, the reasons for conflict included economic, political and administrative, technological, social, cultural, and historical factors. Economic and political and administrative factors were confirmed as the most important causes of such conflict. Although economic reasons were often deemed more important than political and administrative ones, they always played a preconditioning role. Political and administrative causes often directly led to the outbreak and deterioration of conflict. Second, although multiple approaches have been used to resolve conflicts in grassland areas, governmental intervention and mediation remain the most strongly recognized and widely used approach. The importance of judicial settlement has increased significantly in contemporary practices. Third, both the reasons for and approaches adopted to mitigate conflict affected the effectiveness of the conflict resolution, and the reasons also influenced the selection of appropriate conflict resolution approaches. These findings provide a new theoretical direction for future studies as well as practical implications for resolving conflicts in environmental and other types of public governance in contemporary China and elsewhere.

The Dual Effect of COVID-19 on Intergroup Conflict in the Korean Peninsula.

The coronavirus pandemic has fundamentally shifted the way human beings interact, both as individuals and groups, in the face of such a widespread outbreak. This paper seeks to investigate the effects of COVID-19 on intergroup emotions and attitudes within an intractable intergroup conflict, specifically, through the lens of the Korean conflict. Using a two-wave, cross-sectional design, this study was able to track the profound psychological changes in intergroup emotions and attitudes both prior to the pandemic and during its onslaught. Results of these two wave representative samples show that South Korean citizens demonstrated higher levels of fear of their neighbors in North Korea after the outbreak of COVID-19 than before. In turn, this led to increased societal support of hostile government policies towards North Koreans. Conversely, the same participants exhibited higher levels of empathy towards North Koreans during the pandemic, which led to a higher willingness to collaborate with their outgroup. This dual effect on intergroup emotions within intractable conflicts brings forth new avenues from which societies may be able to restrain the destructive influence of the COVID-19 threat on intergroup relations - as well as harvesting its constructive potential for reconciling warring intergroup relations.

The relationship between cognitive control and lexical conflict resolution in developmental dyslexia.

Previous studies have revealed that cognitive control functions contribute to the resolution of lexical interference. Both cognitive control (CC) deficits and reduced speed of lexical retrieval in Rapid Automatized Naming (RAN) tasks are characteristics of Developmental Dyslexia (DD), but it is still not fully understood how these deficits relate to each other and to reading problems. To examine this question, we tested adolescents with DD (n = 38), poor readers (PR; n = 25) and typical readers (TR; n = 33) matched on age and IQ, on CC functions with Stroop, Stop Signal, Simon, Backward Digit Span and n-back tasks and on lexical retrieval and lexical conflict resolution with RAN of pictures in semantically homogeneous vs. mixed trials. As expected, in the blocked RAN Task DD individuals showed longer naming times and a greater effect of lexical conflict resolution (indexed by difference scores of naming times in the homogeneous and mixed conditions) than TR participants. We also found significant group differences (TR = PR > DD) in CC measures. Naming time was associated with CC, while the lexical interference effect did not show any association with this set of abilities. These findings suggest that DD individuals show impairments in multiple cognitive functions, such as cognitive control, lexical retrieval and lexical conflict resolution. Our results also suggest that CC functions are involved in lexical retrieval, but we have not found evidence for their involvement in lexical conflict resolution processes.

Civility in Health Care: A Moral Imperative.

Civility is an essential feature of health care, as it is in so many other areas of human interaction. The article examines the meaning of civility, reviews its origins, and provides reasons for its moral significance in health care. It describes common types of uncivil behavior by health care professionals, patients, and visitors in hospitals and other health care settings, and it suggests strategies to prevent and respond to uncivil behavior, including institutional codes of conduct and disciplinary procedures. The article concludes that uncivil behavior toward health care professionals, patients, and others subverts the moral goals of health care and is therefore unacceptable. Civility is a basic professional duty that health care professionals should embrace, model, and teach.
