How different levels of biological organization interact to shape each other's function is a central question in biology. One particularly important topic in this context is how individuals' variation in behaviour shapes group-level characteristics. We investigated how fish that express different locomotory behaviour in an asocial context move collectively when in groups. First, we established that individual fish have characteristic, repeatable locomotion behaviours (i.e. median speeds, variance in speeds and median turning speeds) when tested on their own. When tested in groups of two, four or eight fish, we found individuals partly maintained their asocial median speed and median turning speed preferences, while their variance in speed preference was lost. The strength of this individuality decreased as group size increased, with individuals conforming to the speed of the group, while also decreasing the variability in their own speed. Further, individuals adopted movement characteristics that were dependent on what group size they were in. This study therefore shows the influence of social context on individual behaviour. If the results found here can be generalized across species and contexts, then although individuality is not entirely lost in groups, social conformity and group-size-dependent effects drive how individuals will adjust their behaviour in groups.

Barnacle Geese

In group-living species, decisions made by individuals may result in collective behaviours. A central question in understanding collective behaviours is how individual variation in phenotype affects collective behaviours. However, how the personality of individuals affects collective decisions in groups remains poorly understood. Here, we investigated the role of boldness on the decision-making process in different-sized groups of barnacle geese. Naive barnacle geese, differing in boldness score, were introduced in a labyrinth in groups with either one or three informed demonstrators. The demonstrators possessed information about the route through the labyrinth. In pairs, the probability of choosing a route prior to the informed demonstrator increased with increasing boldness score: bolder individuals decided more often for themselves where to go compared with shyer individuals, whereas shyer individuals waited more often for the demonstrators to decide and followed this information. In groups of four individuals, however, there was no effect of boldness on decision-making, suggesting that individual differences were less important with increasing group size. Our experimental results show that personality is important in collective decisions in pairs of barnacle geese, and suggest that bolder individuals have a greater influence over the outcome of decisions in groups.

Numerous studies have reported functional improvements in collective behaviour with increasing group size, however, the possibility that such improvements may saturate or even decline as group size continues to grow have seldom been tested experimentally. Here, we tested the ability of solitary three-spined sticklebacks and those in groups, ranging from 2 to 29 fish, to leave an unfavourable patch of habitat. Our results replicate the findings of previous studies at low group sizes, with the fish initially showing a reduction in their latency to leave the unfavourable habitat as group size increased. As group size continued to increase, however, latency to leave the habitat increased, so that the functional relationship between group size and latency to depart was U-shaped. Our results suggest an optimum group size in this context of between 12 and 20 fish. Underlying this group-level trend was a similar U-shaped relationship between group size and the first fish to leave the habitat, suggesting that at larger group sizes, social conformity to the behaviour of the majority can stifle the ability of fish to innovate—in this case, to induce a collective movement from the unfavourable habitat.

Two experimental studies reveal that customers’ reactions to different levels of recovery compensation differ between a recovery that occurs at the group level (such that every customer knows that every other affected customer receives the same compensation) and one that occurs at the individual level (such that the individual does not know whether and how much compensation other affected customers receive). In both cases, recovery compensation exhibits diminishing returns on compensation size in terms of recovery satisfaction. However, at the group level, the rate at which the returns on compensation diminish is greater and satisfaction reaches a plateau at lower compensation levels than at the individual level. The salient social comparison made during a group service recovery (GSR), as evidenced by the mediating role of distributive justice, explains these effects. Finally, we note that at midrange compensation levels, GSR and individual service recovery did not lead to different levels of recovery satisfaction, suggesting a zone of tolerance or indifference at these levels. Further, our findings yield important managerial implications for the efficient allocation of service recovery resources after a group service failure.

The paper examines and compares how the major sociological theories treat axiological issues. Value-driven topics are analysed in view of their relevance to society in times of crisis, when both societal life and the very structure of society undergo dramatic change. Nowadays, social scientists around the world are also witnessing such a change due to the emergence of alternative schools of sociological thought (non-classical, interpretive, postmodern, etc.) and, subsequently, the necessity to revise the paradigms that have been existed in sociology so far. Since the above-mentioned approaches are often used to address value-related issues, building a solid theoretical framework for these studies takes on considerable significance. Furthermore, the paradigm revision has been prompted by technological advances changing all areas of people’s lives, especially social interactions. The global human community, integral in nature, is being formed, and production of human values now matters more than production of things; hence the “expansion” of value-focused perspectives in contemporary sociology. The authors give special attention to collectivities which are higher-order units of the social system. These units are described as well-organised action systems where each individual performs his/her specific role. Just as the role of an individual is distinct from that of the collectivity (because the individual and the collectivity are different as units), so too a distinction is drawn between the value and the norm — because they represent different levels of social relationships. Values are the main connecting element between the society’s cultural system and the social sphere while norms, for the most part, belong to the social system. Values serve primarily to maintain the pattern according to which the society is functioning at a given time; norms are essential to social integration. Apart from being the means of regulating social processes and relationships, norms embody the “principles” that can be applied beyond a particular social system. The authors underline that it is important for Ukrainian sociology to keep abreast of the latest developments in the field of axiology and make good use of those ideas because this is a prerequisite for its successful integration into the global sociological community.

Доводиться, що втрата зв’язку з Батьківщиною, у якій би формі це не відбувалося, не дозволяє митцю творчо самореалізуватися повною мірою. The importance and problematic range of local government reform in the regions of the country and ways of its solution in the field of culture are analyzed. The most effective steps are proposed for management structures at different levels to change attitudes of both the management and the local population regarding different cultural practices. Emphasis is placed on the role of sectoral methodological services in the implementation of this reform. The experience of other countries in activating the local population in this process is emphasized. An attempt has been made to offer effective, in the authors' opinion, solutions to the reform. Emphasis is placed on the educational factor.

This book sheds further light on the nature of church reform and the roots of the Second Vatican Council (1962–65) through a study of eighteenth-century Catholic reformers who anticipated the Council. The most striking of these examples is the Synod of Pistoia (1786), the high-water mark of late Jansenism. Most of the reforms of the Synod were harshly condemned by Pope Pius VI in the bull Auctorem fidei (1794), and late Jansenism was totally discredited in the ultramontane nineteenth-century Church. Nevertheless, much of the Pistoian agenda—such as an exaltation of the role of bishops, an emphasis on infallibility as a gift to the entire Church, religious liberty, a simpler and more comprehensible liturgy that incorporates the vernacular, and the encouragement of lay Bible reading and Christocentric devotions—was officially promulgated at Vatican II. The career of Bishop Scipione de’ Ricci (1741–1810) and the famous Synod he convened are investigated in detail. The international reception (and rejection) of the Synod sheds light on why these reforms failed, and the criteria of Yves Congar are used to judge the Pistoian Synod as “true or false reform.” This book proves that the Synod was a “ghost” present at Vatican II. The council fathers struggled with, and ultimately enacted, many of the same ideas. This study complexifies the story of the roots of the Council and Pope Benedict XVI’s “hermeneutic of reform,” which seeks to interpret Vatican II as in “continuity and discontinuity on different levels” with past teaching and practice.

Concerns about misperceptions among the public are rampant. Yet, little work explores the correlates of misperceptions in varying contexts – that is, how do factors such as group affiliations, media exposure, and lived experiences correlate with the number of misperceptions people hold? We address these questions by investigating misperceptions about COVID-19, focusing on the role of racial/ethnic, religious, and partisan groups. Using a large survey, we find the number of correct beliefs held by individuals far dwarfs the number of misperceptions. When it comes to misperceptions, we find that minorities, those with high levels of religiosity, and those with strong partisan identities – across parties – hold a substantially greater number of misperceptions than those with contrasting group affiliations. Moreover, we show other variables (e.g., social media usage, number of COVID-19 cases in one’s county) do not have such strong relationships with misperceptions, and the group-level results do not reflect acquiescence to believing any information regardless of its truth value. Our results accentuate the importance of studying group-level misperceptions on other scientific and political issues and developing targeted interventions for these groups.

More than 150 cities around the world have expanded emergency cycling and walking infrastructure to increase their resilience in the face of the COVID 19 pandemic. This tendency toward walking has led it to becoming the predominant daily mode of transport that also contributes to significant changes in the relationships between the hierarchy of walking needs and walking behaviour. These changes need to be addressed in order to increase the resilience of walking environments in the face of such a pandemic. This study was designed as a theoretical and empirical literature review seeking to improve the walking behaviour in relation to the hierarchy of walking needs within the current context of COVID-19. Accordingly, the interrelationship between the main aspects relating to walking-in the context of the pandemic- and the different levels in the hierarchy of walking needs were discussed. Results are presented in five sections of “density, crowding and stress during walking”, “sense of comfort/discomfort and stress in regard to crowded spaces during walking experiences”, “crowded spaces as insecure public spaces and the contribution of the type of urban configuration”, “role of motivational/restorative factors during walking trips to reduce the overload of stress and improve mental health”, and “urban design interventions on arrangement of visual sequences during walking”.
