Pukhtunwali: Ostracism and honor among the Pathan Hill tribes

The Pathan Hill tribes provide an example of the functional role of ostracism in a face- to-face, kin-based society. “Pukhtunwali,” the Code of the Pathans, regulates the uses of ostracism, as a response to the conflict between an individual's desire for freedom and the necessity of tribal unity. The most striking use of ostracism among the Pathans is the rejection by the tribe or clan of one of its own members whose behavior might lead to feud. If a member of a group has committed an act likely to provoke a reprisal, which may be directed against any individual of that group, the guilty person may be expelled. By ostracizing the person, the group is both punishing him, and withdrawing its support. In Pathan society ostracism functions simultaneously to deter behavior that violates customary legal norms, to punish specific acts that are culturally defined as improper, and to unify the primary reference group on which individuals depend for protection and economic support.     

Dan Salah Tawfik (1955‐2021)—A giant of protein evolution

It was with great sorrow that we have learned of the untimely death of our friend, mentor, collaborator, and hero, Dan Tawfik. Danny was a true legend in the field of protein function and evolution. He had an incredibly creative mind and a breadth of knowledge—his interests spanned chemistry and engineering to genetics and evolution—that allowed him to see connections that the rest of us could not. More importantly, he made solving biochemical mysteries fun: He was passionate about his work, and his face lit up with joy whenever he talked about scientific topics that excited him (of which there were a lot). Conversations with Danny made us all smarter by osmosis.Danny’s own evolution in science began with physical organic chemistry and biochemistry. His PhD at the Weizmann Institute of Science, awarded in 1995, was on catalytic antibodies under the supervision of Zelig Eshhar and Michael Sela. It was followed by a highly productive period at the University of Cambridge’s Centre for Protein Engineering, first as a postdoctoral fellow with Alan Fersht and Tony Kirby, and then as a senior researcher. Among his many achievements during his time in Cambridge was the demonstration that off‐the‐shelf proteins—the serum albumins—could rival the best catalytic antibodies in accelerating the Kemp elimination reaction due to non‐specific medium effects. This work was an early example of unexpected catalytic promiscuity, and it sowed the seed for Danny’s later fascination with “esoteric, niche enzymology” that went far beyond convenient model systems.It was also in Cambridge where Danny first realized the power of the then new field of directed evolution, both for biotechnology and for elucidating evolutionary processes. He and Andrew Griffiths pioneered emulsion‐based in vitro compartmentalization. The idea of controlling biochemical reactions in separate aqueous droplets inspired emulsion PCR and next‐generation sequencing technologies, whereas Danny used it to solve a long‐standing problem in directed evolution; in vitro selection techniques had always been good at identifying ligand‐binding proteins, but compartmentalization finally enabled the directed evolution of ultra‐fast catalysts.Danny returned to Israel in 2001 to join the faculty of the Weizmann Institute of Science where his scientific trajectory further evolved, diverged, and even “drifted”. He developed new methods for enzyme engineering and applied his evolutionary insights into de novo protein design efforts. In this context, Danny’s interest was always focused on how proteins evolve, particularly the connection between promiscuity, conformational diversity, and evolvability. His depth of understanding underpinned both applied research, such as engineering enzymes to detoxify nerve agents, and fundamental research, such as the evolution of enzymes from non‐catalytic scaffolds.Through it all, Danny retained his sense of joy and wonder at the “beautiful aspects of Nature’s chemistry”. This includes his discovery of an exquisite molecular specificity mechanism mediated by a single, short H‐bond that enables microbes to scavenge phosphate in arsenate‐rich environments. In recent years, he deciphered the biosynthetic mechanism of dimethyl sulfide, “the smell of the sea”, and homed in on the interplay between the evolution of an enzyme, its host organism, and environmental complexity. His insights into how the first proteins emerged caused tremendous excitement in the field. He established the roots of two common enzyme lineages, the Rossmann and P‐loop NTPases, as simple polypeptides, and suggested ornithine as the first cationic amino acid. Prior to his death, he published the results of another tour de force: evidence that the first organisms to utilize oxygen may have appeared much earlier than thought.His work impacted many research fields, and he won many significant awards. Most recently, Danny was awarded the EMET Prize for Art, Science and Culture (2020), informally dubbed “Israel’s Nobel Prize”. He was an active and valued member of the EMBO community, having been elected in 2009, and, until his passing, served on the Editorial Advisory Board of EMBO Reports.Danny was also a superb science communicator. Both his research articles and reviews are a joy to read. What stood out just as much as his brilliance was his personality, as he embodied the Yiddish concept of being a true “mensch”. Danny was humble, was down‐to‐earth, and treated all his colleagues—including the most junior members of our research teams—as equals. He championed the careers of others, both those who worked directly for him and those who were lucky enough to be “just” his friends and collaborators. He believed in us even when we did not believe in ourselves, and he was always there to answer questions both scientific and professional. While he loved to share his own ideas, he would be just as excited about ours. Despite his own busy schedule, he always found the time to help others. He was also excellent company, with a great, very dry, sense of humor, and endless interesting stories, including from his own colorful life. In the days after his untimely death, an often‐repeated phrase was “he was my best friend”. Danny’s former group members have gone on to be highly successful in both industry and academia, including more than 15 former doctoral and postdoctoral researchers who are now faculty. The network of researchers Danny has trained, mentored, or influenced is broad, and this legacy is testament to his qualities as both a scientist and a person.Danny was born in Jerusalem to an Iraqi Jewish family, and his Arabic Jewish identity was important to him. He believed strongly in coexistence and peace, and very much valued the Arabic part of his heritage. In his own words: “I am an Israeli, a Jew, an Arab, but first and foremost a human being”. He would often speak of the achievements of his children with immense pride. Danny also had a passion for being outdoors, especially climbing and hiking—when the best discussions were often to be had (Fig ​(Fig1).1). One of the easiest ways to persuade him to come for a seminar, a collaborative visit, or a conference was to have access to high‐quality climbing in the area. He passed away in a tragic rock‐climbing accident, doing what he loved most outside of science. Our thoughts are with his partner Ita and his children, and we join the much broader community of friends, collaborators, and colleagues whose hearts are broken by his sudden loss.Open in a separate windowFigure 1Dan Salah Tawfik (1955–2021)Photo courtesy of Prof. Joel Mackay, The University of Sydney.     

The Relationship between Trait Emotional Intelligence and Interaction with Ostracized Others' Retaliation

Background

Regulation of emotions in others is distinct from other activities related to trait emotional intelligence in that only such behavior can directly change other people''s psychological states. Although emotional intelligence has generally been associated with prosociality, emotionally intelligent people may manipulate others'' behaviors to suit their own interests using high-level capabilities to read and manage the emotions of others. This study investigated how trait emotional intelligence was related to interacting with ostracized others who attempt retaliation.

Method

We experimentally manipulated whether two people were simultaneously ostracized or not by using an online ball-tossing game called Cyberball. Eighty university students participated in Cyberball for manipulating ostracism and a “recommendation game,” a variation of the ultimatum game for assessing how to interact with others who attempt retaliation, with four participants. After the recommendation game, participants rated their intention to retaliate during the game.

Results

People with higher interpersonal emotional intelligence were more likely to recommend that the ostracized other should inhibit retaliation and maximize additional rewards when they have a weaker intention to retaliate. However, they were more likely to recommend that the ostracized other should retaliate against the ostracizers when they have a stronger intention to retaliate.

Conclusion

This is the first laboratory study that empirically reveals that people with high interpersonal emotional intelligence influence others'' emotions based on their own goals contrary to the general view. Trait emotional intelligence itself is neither positive nor negative, but it can facilitate interpersonal behaviors for achieving goals. Our study offers valuable contributions for the refinement of the trait emotional intelligence concept in the respect of its social function.     

Reading the Mind in the Eyes or Reading between the Lines? Theory of Mind Predicts Collective Intelligence Equally Well Online and Face-To-Face

Recent research with face-to-face groups found that a measure of general group effectiveness (called “collective intelligence”) predicted a group’s performance on a wide range of different tasks. The same research also found that collective intelligence was correlated with the individual group members’ ability to reason about the mental states of others (an ability called “Theory of Mind” or “ToM”). Since ToM was measured in this work by a test that requires participants to “read” the mental states of others from looking at their eyes (the “Reading the Mind in the Eyes” test), it is uncertain whether the same results would emerge in online groups where these visual cues are not available. Here we find that: (1) a collective intelligence factor characterizes group performance approximately as well for online groups as for face-to-face groups; and (2) surprisingly, the ToM measure is equally predictive of collective intelligence in both face-to-face and online groups, even though the online groups communicate only via text and never see each other at all. This provides strong evidence that ToM abilities are just as important to group performance in online environments with limited nonverbal cues as they are face-to-face. It also suggests that the Reading the Mind in the Eyes test measures a deeper, domain-independent aspect of social reasoning, not merely the ability to recognize facial expressions of mental states.     

Personal Features of Identification and Uniqueness in the Anthropological Field of Social Discourse

In this article, fashion is understood as a means by which an individual gains access and gradual establishment as a participant in a social environment. Fashion can be seen as the evolution of the expression of specific views on the external expression of a person’s common understanding. Then it is perceived too as an element of clothing and a person’s overall wardrobe. In a broader sense, as shown here, fashion is thought of as a social standard that is fulfilled only when it corresponds to a common cultural perception of the social order. The relevance is determined in particular by the fact that fashion is part of the mass culture and can form the appearance of a person.

Thus we understand fashion as part of mass culture, and its impact on the personal formation and development of people in the modern society becomes the subject of study. In particular, the set of fashion elements of youth is taken, in addition to development in the social environment itself.

The novelty of this study lies in determining that a person perceives fashion not only in the process of his/her professional development but also in the processes of developing their own emotional and personal status. Youth is most vulnerable to this. We have studied university students who were born during the phase of the post-Soviet state’s formation. For the first time results can be presented on the basis of the analysis of that generation, which determines their way of life after the transition period. A further direction and application of this study are in forming a link that will create a correlation between current fashion trends and the opportunities young people have for social adaptation.     

Names and naming: Instances from the ORU-IGBO

Conclusion People have many names. But, changing one's name is no small thing. It can signify a major step in life or an embarrassing story, as in the last case.A person has a complex individual identity. His collective identity is clear from the moment he is conceived. He is one with a body of people, his kinsmen, who share one common ancestor and through him access to land and resources. The continuation of this group and its name is perpetuated through paternal descent.Kingroup membership ensures a person's place in life, his right to exist, eat, live and enjoy. But, who is he, apart from being a kinsman? Which kinsman is he? How are people going to interact with him? His individual identity will become clear through time. He is a re-incarnation of ancestor x. The circumstances of his birth were such. He behaves like this. He has these personal traits. This has happened to him. He has achieved that. There is no permanent role attached to an individual. He is neither bound to class nor caste. He is dynamic and changes constantly. His life is one of achievement, constant striving and upward mobility till death — when it all begins again. His name signals his state of being in time and existence.Sabine Jell-Bahlsen is an anthropologist and filmmaker.     

Mirrors,monkeys, and group dynamics

When presented with his/her own reflection in a mirror (within an environment that is natural for that particular group of primates) the position that animal holds within the group affects his/her interpretation of that image. Each individual perceives the animal in the mirror to be another animal of equal circumstances as him/herself. An alpha animal sees a potential alpha animal attempting to take over the troop. A beta or lesser animal sees another non-alpha animal attempting to enter the troop through affiliation. In this study a group of zoo raised Japanese macaques were challenged with their own reflection in a mirror. Incidents of aggressive behavior rose in the alpha animals while all affiliative behavior ceased between members of the group. The lesser animals vied for time with the mirror, each attempting to be near the perceived con-specific.     

Competition over Personal Resources Favors Contribution to Shared Resources in Human Groups

Members of social groups face a trade-off between investing selfish effort for themselves and investing cooperative effort to produce a shared group resource. Many group resources are shared equitably: they may be intrinsically non-excludable public goods, such as vigilance against predators, or so large that there is little cost to sharing, such as cooperatively hunted big game. However, group members'' personal resources, such as food hunted individually, may be monopolizable. In such cases, an individual may benefit by investing effort in taking others'' personal resources, and in defending one''s own resources against others. We use a game theoretic “tug-of-war” model to predict that when such competition over personal resources is possible, players will contribute more towards a group resource, and also obtain higher payoffs from doing so. We test and find support for these predictions in two laboratory economic games with humans, comparing people''s investment decisions in games with and without the options to compete over personal resources or invest in a group resource. Our results help explain why people cooperatively contribute to group resources, suggest how a tragedy of the commons may be avoided, and highlight unifying features in the evolution of cooperation and competition in human and non-human societies.     

Primate social behavior and ostracism

Ostracism, and its attendant processes, emigration and immigration, are now recognized as basic mechanisms intrinsic to the long-term adaptation of primate society. Ostracism, defined as socially determined exclusion from the resources and opportunities necessary to successful reproduction, is a basic mechanism by which individuals strive to maximize their own reproductive success at the expense of others. Among males this process most often involves exclusion from opportunities to fertilize females (zygote formation) whereas among females it leads to competition for the resources necessary to raise these zygotes to adulthood. Ostracism from intrasexual competition may be so intense that it leads to the migration of less successful individuals into social groups offering greater opportunity. The “passports” most often used in primate immigration are sexual affinity and kinship alliance. Migration carries high risk and is associated with increased mortality and morbidity. Nevertheless, ostracism, emigration, and immigration remain as the basic social processes by which the ratio of resources to individuals shifts and balances from one year to the next. Such adjustments are made through the process of individual “decisions” and “strategies” to optimize personal reproductive success, but their net effect is to constantly redistribute individuals in relation to resources vital to reproduction.     

Reputation,a universal currency for human social interactions

Decision rules of reciprocity include ‘I help those who helped me’ (direct reciprocity) and ‘I help those who have helped others’ (indirect reciprocity), i.e. I help those who have a reputation to care for others. A person''s reputation is a score that members of a social group update whenever they see the person interacting or hear at best multiple gossip about the person''s social interactions. Reputation is the current standing the person has gained from previous investments or refusal of investments in helping others. Is he a good guy, can I trust him or should I better avoid him as a social partner? A good reputation pays off by attracting help from others, even from strangers or members from another group, if the recipient''s reputation is known. Any costly investment in others, i.e. direct help, donations to charity, investment in averting climate change, etc. increases a person''s reputation. I shall argue and illustrate with examples that a person''s known reputation functions like money that can be used whenever the person needs help. Whenever possible I will present tests of predictions of evolutionary theory, i.e. fitness maximizing strategies, mostly by economic experiments with humans.     

CHILD DEVELOPMENT—Problems of Discipline,Authority and Rebellion

It is only through the love and approval of the significant adults in a child''s life that he is able to give up his primitive behavior for that which meets the demands of social living. Conflict over authority is only one of many conflicts. There are conflicts which arise inherently in a child''s development. The task of the parents in the education of the child in our society is to enable the child to tolerate a certain amount of frustration and also a necessary degree of control of impulses so that he can live in a group and in conformity with the required standards.Increased rebelliousness and defiance are normally characteristic of certain periods of development in healthy children. These are when concerted discipline begins, and in early adolescence. But other events also may reactivate or stimulate attitudes of defiance and rebellion. Even in his rebellion, a child needs and expects his parents to stand for order, as well as for love. He expects that the parent will save him from the consequences of his own destructive impulses, which he as yet may not have the strength to withstand.Deep-seated or submerged factors in the parents may play a significant role in the discipline to which they subject their children. True permissiveness means allowing a child to develop according to his own rate of speed and his own potentialities as a unique individual. It includes refusing the child any type of behavior that will bring danger to him or to others.A parent who uses harsh and rigid forms of discipline may force a child into submission, rather than acceptance and understanding. This produces only surface conformity which hides insecurity and violent underlying destructiveness.

Charles Davies Sherborn and the “Indexer’s Club”

The first few words of the title of this symposium are “Anchoring Biodiversity Information”. In order to properly anchor anything for a long-lasting future, a solid foundation needs to have been laid. For the zoological portion of biodiversity information, that firm foundation is best exemplified in the works of Charles Davies Sherborn. This man, like others of his ilk, was intimately focused on indexing names. This incredible focus was a life-long passion for him and culminated in his 9500-page Index Animalium of over 400,000 names of animals. This Index represents not only one of the most prodigious efforts in publication by a single man and the single most important reference to names in zoology, but a permanent legacy to the efforts of an indexer that proved to be an inspiration to many.     

Economic Decisions for Others: An Exception to Loss Aversion Law

In everyday life, people often make decisions on behalf of others. The current study investigates whether risk preferences of decision-makers differ when the reference point is no longer their own money but somebody else money. Thirty four healthy participants performed three different monetary risky choices tasks by making decisions for oneself and for another unknown person. Results showed that loss aversion bias was significantly reduced when participants were choosing on behalf of another person compared to when choosing for themselves. The influence of emotions like regret on decision-making may explain these results. We discuss the importance of the sense of responsibility embodied in the emotion of regret in modulating economic decisions for self but not for others. Moreover, our findings are consistent with the Risk-as-feelings hypothesis, suggesting that self-other asymmetrical behavior is due to the extent the decision-maker is affected by the real and emotional consequences of his/her decision.     

Setting Free the Son,Setting Free the Widow: Relational Transformation in Arrernte Life-Cycle Rituals (Central Australia)

ABSTRACT

In Australian Aboriginal society, personal identity is an evolving process whose successive mutations derive from a person’s capacity to enter into new relationships. Both initiation rites and funerary practices act to mediate such relational transformations. Drawing on Spencer and Gillen’s material on the Arrernte, this paper establishes a parallel between the procedures put into effect to render a son autonomous from his mother in the course of male initiation, and those undertaken to emancipate a widow from her deceased husband. Both ritual operations introduce a relational distancing within a totality. This totality is composed of two individuals whose antecedent close physical intimacy could thwart these persons’ ability to become an autonomous agent. The rituals make the person capable of entering a new intimate relationship: marriage in the case of a son and remarriage in the case of a widow. Both procedures entail the intervention of ritual objects closely connected to an individual’s personal identity: on the one hand, the churinga, a man is joined with at the end of his initiation and which allows him to exercise responsibilities in fertility rites, and on the other hand, the decaying, contaminating corpse a husband leaves behind upon his death.     

It's a Wonderful Life: A Career as an Academic Scientist

Many years of training are required to obtain a job as an academic scientist. Is this investment of time and effort worthwhile? My answer is a resounding “yes.” Academic scientists enjoy tremendous freedom in choosing their research and career path, experience unusual camaraderie in their lab, school, and international community, and can contribute to and enjoy being part of this historical era of biological discovery. In this essay, I further elaborate by listing my top ten reasons why an academic job is a desirable career for young people who are interested in the life sciences.Students are attracted to careers in academic science because of their interest in the subject rather than for financial reward. But then they hear messages that make them think twice about this career choice. It is difficult to find a job: “Hear about Joe? Three publications as a postdoc and still no job offers.” The NIH pay line is low: “Poor Patricia, she is now on her third submission of her first NIH grant.” Publishing is painful: “Felix''s grad school thesis work has been rejected by three journals!” Academic jobs are demanding: “Cathy has spent her last three weekends writing grants rather than being with her family.”Such scenarios do take place, but if you think that this is what a career in academic science is about, then you need to hear the other side of the story. And this is the purpose of this article—a chance to reflect on the many good things about the academic profession. In the classic movie It''s a Wonderful Life, George Bailey is at the point of despair but regains his confidence through the wisdom and perspective of a guardian angel, Clarence. Doubt and setbacks also are bound to happen in science (as is true of other careers), but pessimism should not rule the day. It is a great profession and there are many happy endings. I would like to share my top ten reasons of why being an academic professor is a “wonderful life,” one that bright and motivated young people should continue to aspire to pursue.     

The Effect of Ostracism and Optional Participation on the Evolution of Cooperation in the Voluntary Public Goods Game

Not only animals, plants and microbes but also humans cooperate in groups. The evolution of cooperation in a group is an evolutionary puzzle, because defectors always obtain a higher benefit than cooperators. When people participate in a group, they evaluate group member’s reputations and then decide whether to participate in it. In some groups, membership is open to all who are willing to participate in the group. In other groups, a candidate is excluded from membership if group members regard the candidate’s reputation as bad. We developed an evolutionary game model and investigated how participation in groups and ostracism influence the evolution of cooperation in groups when group members play the voluntary public goods game, by means of computer simulation. When group membership is open to all candidates and those candidates can decide whether to participate in a group, cooperation cannot be sustainable. However, cooperation is sustainable when a candidate cannot be a member unless all group members admit them to membership. Therefore, it is not participation in a group but rather ostracism, which functions as costless punishment on defectors, that is essential to sustain cooperation in the voluntary public goods game.     

The Walking Behaviour of Pedestrian Social Groups and Its Impact on Crowd Dynamics

Human crowd motion is mainly driven by self-organized processes based on local interactions among pedestrians. While most studies of crowd behaviour consider only interactions among isolated individuals, it turns out that up to 70% of people in a crowd are actually moving in groups, such as friends, couples, or families walking together. These groups constitute medium-scale aggregated structures and their impact on crowd dynamics is still largely unknown. In this work, we analyze the motion of approximately 1500 pedestrian groups under natural condition, and show that social interactions among group members generate typical group walking patterns that influence crowd dynamics. At low density, group members tend to walk side by side, forming a line perpendicular to the walking direction. As the density increases, however, the linear walking formation is bent forward, turning it into a V-like pattern. These spatial patterns can be well described by a model based on social communication between group members. We show that the V-like walking pattern facilitates social interactions within the group, but reduces the flow because of its “non-aerodynamic” shape. Therefore, when crowd density increases, the group organization results from a trade-off between walking faster and facilitating social exchange. These insights demonstrate that crowd dynamics is not only determined by physical constraints induced by other pedestrians and the environment, but also significantly by communicative, social interactions among individuals.     

THE THORNY CHILD

Too many physicians—and parents—hide behind the overworked excuse that “Johnny is just going through a stage.” If the remark is inaccurate a great disservice can be done to both mother and child, and ultimately to society. The well oriented physician would no more permit a young mother to unwittingly feel “guilty” because her two-year-old “little stinker” behaves like a two-year-old little stinker than he would casually reassure when a ten-year-old behaves as though he were two.Actually much of the unpleasant behavior of children is quite normal. If physicians would help all young mothers to recognize this without dismissing abnormal behavior, it would do much to avert the overwhelming sense of inadequacy that so many modern young mothers feel—especially with their first baby. If they can be made comfortable with their first the others usually come easily. Many physicians who care for children are not trained in the rudiments of developmental behavior. By means of a simple outline and drawing of “the thorny child” even the least of the experts can better understand some of the chronologic variations in developmental behavior.
