The authors address unanswered questions about the attraction of the often stormy large group and the interplay between it and small groups. If the large group is a place that arouses many difficult feelings, why do people in conferences, workshops, training programmes and on the Internet continue to participate in them? The authors found that within Internet large groups there was a clear pattern of setting up a small, intimate core group. They found a similar pattern in two live, group workshops. The authors learned that large and small groups are intricately related, and that when participants have the chance, they choose to continue in an on-going, back-and-forth movement between each.

Virtual Instruction

The coronavirus disease 2019 (COVID-19) pandemic has had a major impact on education at all age levels, including professional schools and health professions programs. We describe the experience of adapting preclinical medical school courses within an integrated curriculum to virtual instruction. A major feature of two of the courses were pathology small groups adapted from pathology courses in the previous medical school curriculum. These small groups were designed to use facilitated groups of 8 to 10 students. With a sudden change to virtual learning, these small groups were shifted to large group virtual sessions. In general, the conversion went well, with ongoing optimization of the format of the large group sessions mainly occurring over the first several sessions. End-of-course student evaluations were generally positive, but with a preference toward returning to live sessions in the future. Scores on 5 multiple choice examinations in the spring 2020 course were essentially identical in mean, standard deviation, and distribution to examinations in the previous 2 years of the course that had similar layout and topic organization. We discuss the challenges and successes of the switch to virtual instruction and of teaching pathology content within an integrated medical school curriculum.

Abstract Group-identification and cognition: Why trivial conventions are more important than we think In existing (evolutionary) explanations for group formation and -identification, the function of cultural conventions such as social etiquette and dress codes is limited to providing group-markers. Group formation and identification itself is explained in terms of less arbitrary and more substantial phenomena such as shared norms and institutions. In this paper I will argue that, however trivial and arbitrary, cultural conventions fulfil an important cognitive function that makes them essential to the formation of and identification with large groups. Complex role-division, both informal and institutional, is important in the functioning of any large group of people. Shared conventions enable a virtually automatic understanding of signals, scripts and rules that regulate the interaction of divided roles. They provide a cultural infrastructure within which we perceive e.g. specific behavior and clothing as a range of social-cultural affordances for role-interactions. Shared familiarity with this infrastructure is the foundation for the basic kind of trust of in-group strangers that is a requirement for the formation of large groups. This non-intellectualist view on group formation and group identification can contribute to new ways of dealing with problems in multicultural societies.

The ability to form cooperative societies may explain why humans and social insects have come to dominate the earth. Here we examine the ecological consequences of cooperation by quantifying the fitness of cooperative (large groups) and non-cooperative (small groups) phenotypes in burying beetles (Nicrophorus nepalensis) along an elevational and temperature gradient. We experimentally created large and small groups along the gradient and manipulated interspecific competition with flies by heating carcasses. We show that cooperative groups performed as thermal generalists with similarly high breeding success at all temperatures and elevations, whereas non-cooperative groups performed as thermal specialists with higher breeding success only at intermediate temperatures and elevations. Studying the ecological consequences of cooperation may not only help us to understand why so many species of social insects have conquered the earth, but also to determine how climate change will affect the success of these and other social species, including our own.

This chapter examines the tactical aspects of terrorism. It begins by focusing on the nature of war and conflict in the 21st century, suggesting that technology, economic structures, and communication have changed the way war is waged. It argues that small groups of aggrieved people may conduct campaigns of unconventional warfare against individual nations or international alliances. Although such violence is manifested in many ways, it is typically labeled as “terrorism.” The chapter also demonstrates how large groups and nation states may participate in terrorist activities by either using terrorist tactics or supporting terrorist groups. The next part of the chapter focuses on the specific actions that constitute the tactics of terrorism, examining tactical innovations within various campaigns. The chapter concludes with an analysis of tactical force multipliers, and it introduces the role of the media within this context.

A problem faced by nascent entrepreneurs is to attract outside capital to finance a new venture. A new promising funding mechanism created outside the banking system is crowdfunding (CF). The reward-based model of CF allows nascent entrepreneurs to capture funds from a large group of small investors through a campaign on the Internet. In return for the contribution of the backers, crowdfundees provide rewards (tangible items or services) or other types of incentives. However, in order to be successful a campaign must be designed according to a strategy that encompasses important steps. This study collects data from projects posted in the Indiegogo platform to identify the critical factors of a successful reward-based campaign. The results indicate that it is possible to find an explanation for the different levels of success of reward CF campaigns based on the analysis of the characteristics of the project (depth of the description, updates, and type) and its founders (own presentation, number of backers, team involved, and previous experience).

The majority (60 %) of the soils in the Venezuelan Andes are Inceptisols, a large percentage of which are classified as Dystrustepts by the US Soil Taxonomy, Second Edition of 1999. Some of these soils were classified as Humitropepts (high organic - C-OC-soils) and Dystropepts by the Soil Taxonomy prior to 1999, but no equivalent large group was created for high-OC soils in the new Ustepts suborder. Dystrusepts developed on different materials, relief and vegetation. Their properties are closely related with the parent material. Soils developed on transported deposits or sediments have darker and thicker A horizons, a slightly acid reaction, greater CEC and OC contents than upland slope soils. Based on the previous classification into large groups (Humitropepts and Dystropepts) we found that: Humitropepts have a slightly less acid and higher values of CEC than Dystropepts. These properties or characteristics seem to be related to the fact that Humitropepts have a higher clay and OC content than the Dystropepts. Canonical discrimination analysis showed that the variables that discriminate the two great soil groups from each other are OC and silt. Data for Humitropepts are grouped around the OC vector (defining axis 3, principal component analysis), while Dystropepts are associated with the clay and sand vectors, with significant correlation. Given the importance of OC for soil properties, we propose the creation of a new large group named Humustepts for the order Inceptisol, suborder Ustepts.

Abstract Patterns of vigilant behavior of wintering Bald Eagles (Haliaeetus leucocephalus) feeding on spawned salmon were examined in 1983-1984 on the Nooksack River in northwestern Washington. Vigilance in feeding birds has, in general, been attributed to predator detection; however, we proposed an additional function of vigilance in socially feeding birds that are vulnerable to food robbery and possible injury by conspecifics. We tested predictions of two nonexclusive hypotheses: (1) eagles look up while feeding to detect danger from humans, and (2) eagles look up while feeding to detect pirating attempts or avoid injury by conspecifics. Results suggest that the function of vigilance varies, depending on the size of the feeding group. Vigilance patterns of eagles feeding in small groups (1-4 eagles) and medium groups (5-7 eagles0 are consistent with hypothesis 1, whereas those of eagles feeding in large groups (8-14 eagles) are consistent with hypothesis 2. Eagles in small groups were more vigilant (measured as scanning time and rate of head raising) when feeding near potential danger (riverbank cover) than when far from danger. Adult eagles feeding in areas of intense human activity were more vigilant than immatures feeding at the same site and were more vigilant than both adults and immatures feeding at secluded sites. Vigilance declined as group size increased from 1 to 4 eagles, and increased as group size ranged from 8 to 14 eagles. Feeding eagles that were looking up at the time of a pirating attempt were more successful in keeping their food than eagles with their heads down. In feeding areas where human activity was minimal, eagles formed larger groups than at more disturbed sites.
