A growing body of evidence from humans and other animals suggests the amygdala may be a critical neural substrate for emotional processing. In particular, recent studies have shown that damage to the human amygdala impairs the normal appraisal of social signals of emotion, primarily those of fear. However, effective social communication depends on both the ability to receive (emotional appraisal) and the ability to send (emotional expression) signals of emotional state. Although the role of the amygdala in the appraisal of emotion is well established, its importance for the production of emotional expressions is unknown. We report a case study of a patient with bilateral amygdaloid damage who, despite a severe deficit in interpreting facial expressions of emotion including fear, exhibits an intact ability to express this and other basic emotions. This dissociation suggests that a single neural module does not support all aspects of the social communication of emotional state.

This paper addresses the fields of social and service design in development contexts, practice-based and constructive design research. A framework for social design for services will be explored through the survey of existing literature, specifically by drawing on eight doctoral theses that were produced by the World Design research group. The work of World Design researcher-designers was guided by a strong ethos of social and service design for development in marginalised communities. The paper also draws on a case study in Namibia and South Africa titled ‘My Dream World’. This case study presents a good example of how the social design for services framework functions in practice during experimentation and research in the field. The social design for services framework transfers the World Design group’s research results into practical action, providing a tool for the facilitation of design and research processes for sustainable development in marginal contexts.

Hugh Trevor-Roper (Lord Dacre) made several iconoclastic interventions in the field of Scottish history. These earned him a notoriety in Scottish circles which, while not undeserved, has led to the reductive dismissal of Trevor-Roper's ideas, particularly his controversial interpretation of the Scottish Enlightenment, as the product of Scotophobia. In their indignation Scottish historians have missed the wider issues which prompted Trevor-Roper's investigation of the Scottish Enlightenment as a fascinating case study in European cultural history. Notably, Trevor-Roper used the example of Scotland to challenge Weberian-inspired notions of Puritan progressivism, arguing instead that the Arminian culture of north-east Scotland had played a disproportionate role in the rise of the Scottish Enlightenment. Indeed, working on the assumption that the essence of Enlightenment was its assault on clerical bigotry, Trevor-Roper sought the roots of the Scottish Enlightenment in Jacobitism, the counter-cultural alternative to post-1690 Scotland's Calvinist Kirk establishment. Though easily misconstrued as a dogmatic conservative, Trevor-Roper flirted with Marxisant sociology, not least in his account of the social underpinnings of the Scottish Enlightenment. Trevor-Roper argued that it was the rapidity of eighteenth-century Scotland's social and economic transformation which had produced in one generation a remarkable body of political economy conceptualising social change, and in the next a romantic movement whose powers of nostalgic enchantment were felt across the breadth of Europe.

The island marble butterfly (Euchloe ausonides insulanus), thought to be extinct throughout the 20th century until re-discovered on a single remote island in Puget Sound in 1998, has become the focus of a concerted protection effort to prevent its extinction. However, efforts to “restore” island marble habitat conflict with efforts to “restore” the prairie ecosystem where it lives, because of the butterfly’s use of a non-native “weedy” host plant. Through a case study of the island marble project, we examine the practice of ecological restoration as the enactment of particular norms that define which species are understood to belong in the place being restored. We contextualize this case study within ongoing debates over the value of “native” species, indicative of deep-seated uncertainties and anxieties about the role of human intervention to alter or manage landscapes and ecosystems, in the time commonly described as the “Anthropocene.” We interpret the question of “what plants and animals belong in a particular place?” as not a question of scientific truth, but a value-laden construct of environmental management in practice, and we argue for deeper reflexivity on the part of environmental scientists and managers about the social values that inform ecological restoration.

Due to the increasing prevalence of asynchronous learning platforms, the development and implementation of online discussion boards have become important considerations in the design of post-secondary learning environments. This research is conducted as a case study of the online discussion board use in a small engineering education graduate course, consisting of in-class and online discussion components. By varying the structure of the online discussion board to allow different types of student interaction, the study identifies trends in discussion board use, specifically pertaining to student participation, student collaboration, and the integration between in-class and online discussions. As a result, the study provides insight into the utility and limitations of online discussion boards in post-secondary courses.

Social signals, such as changes in gaze direction, are essential cues to predict others’ mental states and behaviors (i.e., mentalizing). Studies show that humans can mentalize with non-human agents when they perceive a mind in them (i.e., mind perception). Robots that physically and/or behaviorally resemble humans likely trigger mind perception, which enhances the relevance of social cues and improves social-cognitive performance. The current ex-periments examine whether the effect of physical and behavioral influencers of mind perception on social-cognitive processing is modulated by the lifelikeness of a social interaction. Participants interacted with robots of varying degrees of physical (humanlike vs. robot-like) and behavioral (reliable vs. random) human-likeness while the lifelikeness of a social attention task was manipulated across five experiments. The first four experiments manipulated lifelikeness via the physical realism of the robot images (Study 1 and 2), the biological plausibility of the social signals (Study 3), and the plausibility of the social con-text (Study 4). They showed that humanlike behavior affected social attention whereas appearance affected mind perception ratings. However, when the lifelikeness of the interaction was increased by using videos of a human and a robot sending the social cues in a realistic environment (Study 5), social attention mechanisms were affected both by physical appearance and behavioral features, while mind perception ratings were mainly affected by physical appearance. This indicates that in order to understand the effect of physical and behavioral features on social cognition, paradigms should be used that adequately simulate the lifelikeness of social interactions.

This study aims to gain a deeper understanding of the existence of the local social organization in conducting community empowerment. The experiment was conducted at Community Empowerment Institution (In Indonesia it is referred to as Lembaga Pemberdayaan Masyarakat/LPM). LPM Cibeunying as one of the local social institution in Bandung regency. Aspects reviewed in the study include the style of leadership, processes, and stages of community empowerment, as well as the LPM network. The research method used is a case study with the descriptive method and qualitative approach. Data collection was conducted against five informants consisting of the Chairman and LPM’s Board members, village officials, and community leaders. The results show that the dominant leadership style is participative, in addition to that, a supportive leadership style and directive leadership style are also used in certain situations. The empowerment process carried out per the stages of the empowerment process is identifying and assessing the potential of the region, problems, and opportunities-chances; arranging a participative activity plan; implementing the activity plan; and monitoring and evaluating the process and results of activities. The social networking of LPM leads to a social network of power in which LPM can influence the behavior of communities and community institutions in utilizing and managing community empowerment programs. From the research, it can be concluded that the model of community empowerment implemented by LPM Cibeunying Village is enabling, empowering, and protecting.

This article reflects on the conceptual debt that anthropology has developed towards the peoples it studies, by exploring the case-study of Gypsy/Roma anthropology. We argue that ethnographically-grounded research has enabled anthropologists to access and incorporate Gypsy/Roma visions and practices of the world. The flexible Gypsy epistemologies, which Gypsies/ Roma use in the social and cultural construction of particular forms of identity and mobility, have thus translated into a specific practice of theory, which has provided more adequate tools for grasping the complexity of reality and contributed to a decolonialisation of anthropological thought.
