In this chapter, my goals are threefold. First, I give a taxonomy of evolutionary explanations of cancer, illustrating distinct types with case studies of explanations of cancer’s origins and prevalence. Second, I argue that cancer progression can be viewed as both a process of selection and a byproduct of selection at distinct levels in the biological hierarchy. Third, I provide a general account of the explanatory role of theoretical models of cancer progression and treatment failure. I use these accounts to illustrate examples of “how possibly” and “a priori” causal modeling.

Abstract. The benefits of talking with others about unpleasant emotions have been thoroughly investigated, but individual differences in distress disclosure tendencies have not been adequately integrated within theoretical models of emotion. The purpose of this laboratory research was to determine whether distress disclosure tendencies stem from differences in emotional reactivity or differences in emotion regulation. After completing measures of distress disclosure tendencies, social desirability, and positive and negative affect, 84 participants (74% women) were video recorded while viewing a sadness-inducing film clip. Participants completed post-film measures of affect and were then interviewed about their reactions to the film; these interviews were audio recorded for later coding and computerized text analysis. Distress disclosure tendencies were not predictive of the subjective experience of emotion, but they were positively related to facial expressions of sadness and happiness. Distress disclosure tendencies also predicted judges’ ratings of the verbal disclosure of emotion during the interview, but self-reported disclosure and use of positive and negative emotion words were not associated with distress disclosure tendencies. The authors present implications of this research for integrating individual differences in distress disclosure with models of emotion.

Although ego-centered network data provide information that is limited in various ways as compared with full network data, an ego-centered design can be used without the need for a priori and researcher-defined network borders. Moreover, ego-centered network data can be obtained with traditional survey methods. However, due to the dynamic structure of the questionnaires involved, a great effort is required on the part of either respondents (with self-administration) or interviewers (with face-to-face interviews). As an alternative, we will show the advantages of using CASI (computer-assisted self-administered interview) methods for the collection of ego-centered network data as applied in a study on the role of social networks in substance use among college students.

The aim of this track was to question the divide between the nature of knowledge understood as experiential in indigenous contexts and science as an objective transferable knowledge. However, these can co-exist and inform design practices within transforming social contexts. The track aimed to challenge the hegemony of dominant knowledge systems, and demonstrate co-existence. The track also hoped to make a case for other systems of knowledges and ways of knowing through examples from native communities. The track was particularly interested in, first, how innovators use indigenous and cultural systems and frameworks to manage or promote innovation and second, the role of local knowledge and culture in transforming innovation as well as the form of local practices inspired innovation. The contributions also aspired to challenge through examples, case studies, theoretical frameworks and methodologies the hegemony of dominant knowledge systems, the divides of ‘academic’ vs ‘non-academic’ and ‘traditional’ vs ‘non-traditional’.

The Sri Lankan Ministry of National Coexistence, Dialogue, and Official Languages published the work “People of Sri Lanka” in 2017. In this comprehensive publication, 21 invited Sri Lankan scholars introduced 19 different people’s groups to public readers in English, mainly targeted at a growing number of foreign visitors in need of understanding the cultural diversity Sri Lanka has to offer. This paper will observe the presentation of these different groups of people, the role music and allied arts play in this context. Considering the non-scholarly design of the publication, a discussion of the role of music and allied arts has to be supplemented through additional analyses based on sources mentioned by the 21 participating scholars and their fragmented application of available knowledge. In result, this paper might help improve the way facts about groups of people, the way of grouping people, and the way of presenting these groupings are displayed to the world beyond South Asia. This fieldwork and literature guided investigation should also lead to suggestions for ethical principles in teaching and presenting of culturally different music practices within Sri Lanka, thus adding an example for other case studies.

Indonesia is the most populous Islamic country and as such is host to a diverse range of Islamic beliefs and practices. Here we examine how the diversity of beliefs and practices among Indonesian Muslims relates to group bonding and parochialism. In particular, we examine the predictive power of two distinct types of group alignment, group identification and identity fusion, among individuals from three Sunni politico-religious groups - a fundamentalist group (PKS), a moderate group (NU), and a control sample of politically unaffiliated citizens. Fundamentalists were more fused to targets than moderates or citizens, but contrary to fusion theory, we found across all groups, that group identification (not fusion) better predicted parochialism, including willingness to carry out extreme pro-group actions. We discuss how religious beliefs and practice impact parochial attitudes, as well as the implications for theoretical models linking fusion to extreme behaviour.

Memory span in humans has been intensely studied for more than a century. In spite of the critical role of memory span in our cognitive system, which intensifies the importance of fundamental determinants of its evolution, few studies have investigated it by taking an evolutionary approach. Overall, we know hardly anything about the evolution of memory components. In the present study, I briefly review the experimental studies of memory span in humans and non-human animals and shortly discuss some of the relevant evolutionary hypotheses.

Abstract: Based on Law Number 2 of 2012 concerning Land Acquisition for Development in the Public Interest, the Openness Principle is one of the ten principles as the basis of the implementation of development. This principle is significant because its complex role can lead to conflicts and disputes. In this paper, discussions are divided into two parts: 1) how the implementation is expected to be applied according to the acquisition procedure in theory; and 2) the reality that occurs in the field. The first discussion was conducted by reviewing the applicable regulations and the methods or concepts of development of the openness principle. Meanwhile, the second discussion about the reality on the field was conducted by elaborating case studies regarding problems in land acquisition. The results of this study indicate that there are gaps in the implementation of the openness principle between theory and reality in regards of land scarcity, economic inequality, and information asymmetry among the involved parties. In conclusion, the implementation of the openness principle is significant with the role of information in land acquisition.Intisari: Berdasarkan Undang Undang Nomor 2 Tahun 2012 tentang Pengadaan Tanah Bagi Pembangunan Untuk Kepentingan Umum, Asas Keterbukaan adalah salah satu dari sepuluh asas yang menjadi dasar pelaksanaannya. Asas ini menjadi signifikan karena perannya yang kompleks dapat menimbulkan konflik dan sengketa. Artikel ini akan membagi pembahasan menjadi dua bagian: pertama, bagaimana implementasi yang seharusnya diterapkan pada prosedur pengadaan secara harapan, dan kedua, membahas mengenai realita yang terjadi di lapangan. Secara harapan pembahasan dilakukan dengan melakukan library research atau studi terhadap peraturan yang berlaku dan metode-metode atau prinsip perkembangan dari asas keterbukaan. Realitas di lapangan akan dielaborasi dari studi kasus mengenai permasalahan dalam pengadaan tanah. Hasil dari penelitian ini menunjukkan ada gap dalam implementasi asas keterbukaan antara harapan dan realitas di lapangan yang bersumber dari kelangkaan sumber daya/tanah, ketimpangan ekonomi dan asimetri informasi di antara para pihak yang terlibat. Tulisan ini menyimpulkan bahwa implementasi asas keterbukaan signifikan dengan peran informasi dalam pengadaan tanah.
