Contested freedoms : British images of Sierra Leone, 1780-1850.

The colony of Sierra Leone, between 1780 and 1850, was a unique practical expression of British antislavery culture and ideology. This thesis reflects on how leading abolitionists imagined this part of West Africa and what they intended to achieve there. The approach is multi-disciplinary and draws on recent theoretical developments to investigate the creation and maintenance of hegemonic images of Sierra Leone and its inhabitants during the colony's early years. The thesis points to Manichean differences of interpretation which underlay images of Sierra Leone's native inhabitants, its black settler and liberated African populations and the abolitionists who supported them. It also reflects widely on images of Africa's physical environment. Throughout, the emphasis is on the struggles for representational dominance which took place not only between antislavery supporters and their opponents but within antislavery culture itself. Much of that struggle centred around early utopian images of the colony. Sierra Leone was a child of modernity at arguably its most optimistic and eloquent phase. It was seen as a place where enlightenment ideologies regarding rights and progress could be practically enacted. The utopian discourse persisted in spite of the colony's apparent commercial failure. However, images of the colony's black inhabitants became increasingly negative. This thesis suggests that humanitarians (in seeking to explain the difficulties they encountered in Sierra Leone) frequently appropriated the hostile images of blacks which had been promoted by their pros lavery opponents. Part Three of this study comprises an examination of travel writing about Sierra Leone. This section builds on recent theoretical advances in our understanding of the importance of travel writing as a cultural signifier. It insists that travel writing (as a promoter of images) is more than just a record of individual journeys and lightweight observations. In particular the thesis examines the role of travellers in perpetuating racist myths about 'other' cultures despite the use of narrative techniques which assert the travellers' vulnerability and innocence. The thesis also reveals how travellers studied and reported land and people within an imperial discursive frame that ultimately sought to appropriate and exploit them

What is the ‘problem’ of gender inequality represented to be in the Swedish forest sector?

Funding Information: We would like to thank our informants for their time and insights, as well as the wider international SEQUAL project (Social-ecological relations and gender equality: Dynamics and processes for transformational change across scales) members. We also thank the two anonymous reviewers who provided valuable comments on this article. This research is funded by the Swedish Research Council (project number 2018-00988 ). Publisher Copyright: © 2022 The AuthorsGender equality in natural resource management is a matter of sustainability and democracy for Sweden's government, however the country's forest remains a highly gender-segregated sector. We examine how gender inequality is problematized within Swedish forest and rural policy documents using the What's the problem represented to be? (WPR) approach. We build on previous efforts to investigate gender inequality in the forest sector by expanding the critical analysis to rural development policy. We conduct interviews with forest experts, owners, and practitioners to shed light on where there are gaps within the policy representations and uncover alternative policy options that are presented. Our findings corroborate that gender inequality is represented to be a technical problem, with policy measures aiming to increase the number of women within a forest sector that continues to maintain rigid conceptions about forestry production values. While there are claims of success in the increase of women within the sector in aggregate, there is little change in the numbers of women in decision-making positions. Forest policy relies upon women to bring growth and sustainability to the forest industry, while rural policy expects women to halt rural population decline. Our findings suggest that merely trying to fit more women into a mold that has been shaped for and by inflexible forestry and masculine values is an impediment not only to gender equality but also to the inclusion of other social groups and ideas in the changing rural landscapes of Sweden.Peer reviewe

Community and Communion Radio: Listening to Evangelical Programmes in a Brazilian Favela

According to academics and regulators, Evangelical and community radio belong to different sectors. Yet, in the favela, the urban environment and set of airwaves were saturated with religious sounds and programmes. On the basis of an ethnographic study of community radio in the everyday life of a favela, this research indicates that the two are often one and the same as the community radio stations would frequently broadcast Evangelical programming. This article argues that rather than trying to discover community radio's functions a priori, it is more helpful do so organically, step by step. What emerges is that such functions are multiple—religious, commercial, political—and not necessarily perceived as being paradoxical by their listeners

Unlocking the unsustainable rice-wheat system of Indian Punjab: Assessing alternatives to crop-residue burning from a systems perspective

Crop residue burning in Indian Punjab emits particulate matter with detrimental impacts on health, climate and that threaten agricultural production. Though legal and technological barriers to residue burning exist – and alternatives considered more profitable to farmers – residue burning continues. We review black carbon (BC) emissions from residue burning in Punjab, analyse social-ecological processes driving residue burning, and rice and wheat value-chains. Our aims are to a) understand system feedbacks driving agricultural practices in Punjab; b) identify systemic effects of alternatives to residue burning and c) identify companies and financial actors investing in agricultural production in Punjab. We find feedbacks locking the system into crop residue burning. The Government of India has greatest financial leverage and risk in the current system. Corporate stakeholders have little financial incentive to enact change, but sufficient stakes in the value chains to influence change. Agricultural policy changes are necessary to reduce harmful impacts of current practices, but insufficient to bringing about sustainability. Transformative changes will require crop diversification, circular business models and green financing. Intermediating financial institutions setting sustainability conditions on loans could leverage these changes. Sustainability requires the systems perspective we provide, to reconnect production with demand and with supporting environmental conditions

A Multidimensional Framework of Collaborative Groups’ Disciplinary Engagement

Abstract This research is aimed at developing novel theory to advance innovative methods for examining how collaborative groups progress toward productively engaging during classroom activity that integrates disciplinary practices. This work draws on a situative perspective, along with prior framings of individual engagement, to conceptualize engagement as a shared and multidimensional phenomenon. A multidimensional conceptualization affords the study of distinct engagement dimensions, as well as the interrelationships of engagement dimensions that together are productive. Development and exploration of an observational rubric evaluating collaborative group disciplinary engagement (GDE) is presented, leveraging the benefits of observational methods with a rubric specifying quality ratings, enabling the potential for analyses of larger samples more efficiently than prior approaches, but with similar ability to richly characterize the shared and multidimensional nature of group engagement. Mixed-methods analyses, including case illustrations and profile analysis, showcase the synergistic interrelations among engagement dimensions constituting GDE. The rubric effectively captured engagement features that could be identified via intensive video analysis, while affording the evaluation of broader claims about group engagement patterns. Application of the rubric across curricular contexts, and within and between lessons across a curricular unit, will enable comparative studies that can inform theory about collaborative engagement, as well as instructional design and practice

Matching scope, purpose and uses of planetary boundaries science

Background: The Planetary Boundaries concept (PBc) has emerged as a key global sustainability concept in international sustainable development arenas. Initially presented as an agenda for global sustainability research, it now shows potential for sustainability governance. We use the fact that it is widely cited in scientific literature (>3500 citations) and an extensively studied concept to analyse how it has been used and developed since its first publication. Design: From the literature that cites the PBc, we select those articles that have the terms 'planetary boundaries' or 'safe operating space' in either title, abstract or keywords. We assume that this literature substantively engages with and develops the PBc. Results: We find that 6% of the citing literature engages with the concept. Within this fraction of the literature we distinguish commentaries—that discuss the context and challenges to implementing the PBc, articles that develop the core biogeophysical concept and articles that apply the concept by translating to sub-global scales and by adding a human component to it. Applied literature adds to the concept by explicitly including society through perspectives of impacts, needs, aspirations and behaviours. Discussion: Literature applying the concept does not yet include the more complex, diverse, cultural and behavioural facet of humanity that is implied in commentary literature. We suggest there is need for a positive framing of sustainability goals—as a Safe Operating Space rather than boundaries. Key scientific challenges include distinguishing generalised from context-specific knowledge, clarifying which processes are generalizable and which are scalable, and explicitly applying complex systems' knowledge in the application and development of the PBc. We envisage that opportunities to address these challenges will arise when more human social dimensions are integrated, as we learn to feed the global sustainability vision with a plurality of bottom-up realisations of sustainability

Fourteen propositions for resilience, fourteen years later

In 2006, Walker et al. published an article titled, “A Handful of Heuristics and Some Propositions for Understanding Resilience in Social-ecological Systems.” The article was incorporated into the Ecology and Society special feature, Exploring Resilience in Social-Ecological Systems. Walker et al. identified five heuristics and posed 14 propositions for understanding resilience in social-ecological systems. At the time, the authors hoped the paper would promote experimentation, critique, and application of these ideas in resilience and social-ecological systems research. To determine the extent to which these propositions have achieved the authors’ hopes, we reviewed the scientific literature on socialecological systems since the article was published. Using Scopus, we identified 627 articles that cited the Walker et al. article. We then identified and assessed the articles relative to each proposition. In addition, we conducted a more general Scopus review for articles that did not cite the Walker et al. article specifically but incorporated a proposition’s concepts. Overall, articles often cite Walker et al. as a reference for a definition of a heuristic or ecological resilience generally and not to reference a specific proposition. Nonetheless, every proposition was at least mentioned in the literature and used to advance resilience scholarship on social-ecological systems. Eleven propositions were tested by multiple articles through application of case studies or other research, and 7 of the 11 propositions were substantially discussed and advanced. Finally, three propositions were heavily critiqued either as concepts in resilience literature or in their application

Distinct contributions of extrastriate body area and temporoparietal junction in perceiving one's own and others' body.

The right temporoparietal cortex plays a critical role in body representation. Here, we applied repetitive transcranial magnetic stimulation (rTMS) over right extrastriate body area (EBA) and temporoparietal junction (TPJ) to investigate their causative roles in perceptual representations of one's own and others' body. Healthy women adjusted size-distorted pictures of their own body or of the body of another person according to how they perceived the body (subjective task) or how others perceived it (intersubjective task). In keeping with previous reports, at baseline, we found an overall underestimation of body size. Crucially, EBA-rTMS increased the underestimation bias when participants adjusted the images according to how others perceived their own or the other woman's body, suggesting a specific role of EBA in allocentric body representations. Conversely, TPJ-rTMS increased the underestimation bias when participants adjusted the body of another person, either a familiar other or a close friend, in both subjective and intersubjective tasks, suggesting an involvement of TPJ in representing others' bodies. These effects were body-specific, since no TMS-induced modulation was observed when participants judged a familiar object. The results suggest that right EBA and TPJ play active and complementary roles in the complex interaction between the perceptions of one's own and other people's body

Born to learn: The inspiration, progress, and future of evolved plastic artificial neural networks

Biological plastic neural networks are systems of extraordinary computational capabilities shaped by evolution, development, and lifetime learning. The interplay of these elements leads to the emergence of adaptive behavior and intelligence. Inspired by such intricate natural phenomena, Evolved Plastic Artificial Neural Networks (EPANNs) use simulated evolution in-silico to breed plastic neural networks with a large variety of dynamics, architectures, and plasticity rules: these artificial systems are composed of inputs, outputs, and plastic components that change in response to experiences in an environment. These systems may autonomously discover novel adaptive algorithms, and lead to hypotheses on the emergence of biological adaptation. EPANNs have seen considerable progress over the last two decades. Current scientific and technological advances in artificial neural networks are now setting the conditions for radically new approaches and results. In particular, the limitations of hand-designed networks could be overcome by more flexible and innovative solutions. This paper brings together a variety of inspiring ideas that define the field of EPANNs. The main methods and results are reviewed. Finally, new opportunities and developments are presented
