Abstract Evolutionary game theory is used to model the evolution of competing strategies in a population of players. Evolutionary stability of a strategy is a dynamic equilibrium, in which any competing mutated strategy would be wiped out from a population. If a strategy is weak evolutionarily stable, the competing strategy may manage to survive within the network. Understanding the network-related factors that affect the evolutionary stability of a strategy would be critical in making accurate predictions about the behaviour of a strategy in a real-world strategic decision making environment. In this work, we evaluate the effect of network topology on the evolutionary stability of a strategy. We focus on two well-known strategies known as the Zero-determinant strategy and the Pavlov strategy. Zero-determinant strategies have been shown to be evolutionarily unstable in a well-mixed population of players. We identify that the Zero-determinant strategy may survive, and may even dominate in a population of players connected through a non-homogeneous network. We introduce the concept of ‘topological stability’ to denote this phenomenon. We argue that not only the network topology, but also the evolutionary process applied and the initial distribution of strategies are critical in determining the evolutionary stability of strategies. Further, we observe that topological stability could affect other well-known strategies as well, such as the general cooperator strategy and the cooperator strategy. Our observations suggest that the variation of evolutionary stability due to topological stability of strategies may be more prevalent in the social context of strategic evolution, in comparison to the biological context.

Why do individuals take different decisions when confronted with similar choices? This paper investigates whether the answer lies in an evolutionary process. Our analysis builds on recent work in evolutionary game theory showing the superiority of a given type of preferences, homo moralis, in fitness games with assortative matching. We adapt the classical definition of evolutionary stability to the case where individuals with distinct preferences coexist in a population. This approach allows us to establish the characteristics of an evolutionarily stable population. Then, introducing an assortment matrix for assortatively matched interactions, we prove the existence of a heterogeneous evolutionarily stable population in 2×2 symmetric fitness games under constant assortment, and we identify the conditions for its existence. Conversely to the classical setting, we find that the favored preferences in a heterogeneous evolutionarily stable population are context-dependent. As an illustration, we discuss when and how an evolutionarily stable population made of both selfish and moral individuals exists in a prisoner’s dilemma. These findings offer a theoretical foundation for the empirically observed diversity of preferences among individuals.

Using Data

The rapid and widespread of COVID-19 has caused severe multifaceted effects on society but differently in women and men, thereby preventing the achievement of gender equality (the 5th sustainable development goal of the United Nations). This study, using data of 355 teleworkers collected in Hanoi (Vietnam) during the first social distancing period, aims at exploring how (dis)similar factors associated with the perception and the preference for more home-based telework (HBT) for male teleworkers versus female peers are. The findings show that 56% of female teleworkers compared to 45% of male counterparts had a positive perception of HBT within the social distancing period and 63% of women desired to telework more in comparison with 39% of men post-COVID-19. Work-related factors were associated with the male perception while family-related factors influenced the female perception. There is a difference in the effects of the same variables (age and children in the household) on the perception and the preference for HBT for females. For women, HBT would be considered a solution post-COVID-19 to solve the burden existing pre-COVID-19 and increasing in COVID-19. Considering gender inequality is necessary for the government and authorities to lessen the adverse effects of COVID-19 on the lives of citizens, especially female ones, in developing countries.

Shed Light

Application of biomimetics has expanded progressively to other fields in recent years, including urban and architectural design, scaling up from materials to a larger scale. Besides its contribution to design and functionality through a long evolutionary process, the philosophy of biomimetics contributes to a sustainable society at the conceptual level. The aim of this review is to shed light on trends in the application of biomimetics to architectural and urban design, in order to identify potential issues and successes resulting from implementation. In the application of biomimetics to architectural design, parts of individual “organisms”, including their form and surface structure, are frequently mimicked, whereas in urban design, on a larger scale, biomimetics is applied to mimic whole ecosystems. The overall trends of the reviewed research indicate future research necessity in the field of on biomimetic application in architectural and urban design, including Biophilia and Material. As for the scale of the applications, the urban-scale research is limited and it is a promising research which can facilitate the social implementation of biomimetics. As for facilitating methods of applications, it is instrumental to utilize different types of knowledge, such as traditional knowledge, and providing scientific clarification of functions and systems based on reviews. Thus, interdisciplinary research is required additionally to reach such goals.

Endogenous Variables

Consumers are seen as limited decision makers who set short-term activity levels from their budgets, stocks of experience, and values following a preference-maximizing heuristic. Disturbances to activity levels in their evolution by exogeneties of social and economic environments, and the feedback of activity levels which agents have no systematic ability to anticipate, reset stock and value levels through the interactive relationships among endogenous variables. Agents then solve the maximization problem for a subsequent period using stock and value levels as modified by the evolutionary process. The dependence of a single-period decision on the stock and value constructs is examined and forms for the dynamic evolution of stock and value constructs that represent the feedback of activity levels to stock and value levels are also introduced. Implications of these forms for the social construction of activities are discussed.

Interest in creativity as a subject of research has been growing exponentially since the second half of the 20th century in all areas of human history. A wide range of both domestic and foreign studies allows authors to assert that creativity is a personality trait, inherent to one degree or another. Whereas the development of such trait becomes an urgent necessity in the new reality. The entire evolutionary process of the social development illustrates its dependence on personal and collective creativity. The aim of this research is to study the phenomenon of creativity through the perspective of axiology, i.e. the science of values. Axiology allows us to consider the realities of the modern world from the perspective of not only external factors, circumstances and situations, but also of deep value foundations. Creativity has been studied quite deeply from the point of view of psychology: the special characteristics of a creative person, stages of the creative process, the relationship between creative and critical thinking, creativity and intelligence. Some psychologists emphasize motivation, creative skills, interdisciplinary knowledge, and the creative environment as the main components that contribute to the development of creativity. The authors of the article argue that values and value orientations towards cognition, creativity, self-realization and self-expression are the drivers of creativity. In a broad sense, values as a matrix of culture determine the attitude of society to creativity, to the development of creativity of the individual and the creative class, and to how economically successful a given society will be. Since innovation and entrepreneurship are embodied creativity. Thus, the study of creativity from the perspective of axiology combines the need for a deep study of this phenomenon and the subjective significance of creativity in the context of new realities

Ageing is a universal phenomenon that has not only social but also economic, political, and health-related implications. With the advancement in healthcare facilities and better availability of health services, the geriatric population is gradually increasing. But, this group is at an increased risk of developing both physical and psychological co-morbidities due to age-related factors and changes in the social circumstances. The present chapter proposes the concept and issues related to co-morbidity in the geriatric population. After discussing the issues and consequences of medical and psychiatric co-morbidities, their effective treatment regime and care/management in relation to the geriatric population are addressed.

Career Salience

Despite growing academic and practical concerns about IT-transformed workplaces, little research empirically investigates these concerns. This paper adopts a unique approach to address these concerns by evaluating the appropriateness of traditional drivers of career salience in high IT working environments. Building on established measures of role stress, participation in decision making, job involvement and career salience, questionnaires were distributed to staff working in high IT organizations in Nigeria. Multiple regressions were run from a valid response of 223, resulting in the three traditional drivers accounting for 25% of the variance in career salience. Similarly, standardized ß coefficients indicate on job involvement (0.46) makes unique significant contribution to career salience. This finding is in line with sociotechnical theory—that changes in technical sub-system affect the social sub-system and vice versa. The finding also provides indirect exploratory support for the decreasing importance of non-IT factors in the evolving digital workplace. Other implications, limitations and direction for future research are highlighted.

The social entrepreneur has been analyzed from many perspectives, either from its social impact, its proposed social value, or its direct or indirect action. This chapter attempts to analyze the entrepreneur from a new approach: the perspective of the leader. Therefore, the question arises: is leadership in social entrepreneurs an evolutionary process or not? Is it a natural ability or a learned technique? Is the social entrepreneur a leader born or made? To answer this, [1] we will analyze the main contemporary theories of leadership from two different paradigms (Colvin, 2013), [2] we will define new concepts in the world of social entrepreneurship, [3] we will establish a life cycle of strategic leadership promoted by the social entrepreneur focused on his or her organization in order to serve as a seed for the intended social impact.
