Mapping and modelling the geographical distribution and environmental limits of podoconiosis in Ethiopia

BACKGROUND Ethiopia is assumed to have the highest burden of podoconiosis globally, but the geographical distribution and environmental limits and correlates are yet to be fully investigated. In this paper we use data from a nationwide survey to address these issues. METHODOLOGY Our analyses are based on data arising from the integrated mapping of podoconiosis and lymphatic filariasis (LF) conducted in 2013, supplemented by data from an earlier mapping of LF in western Ethiopia in 2008-2010. The integrated mapping used woreda (district) health offices' reports of podoconiosis and LF to guide selection of survey sites. A suite of environmental and climatic data and boosted regression tree (BRT) modelling was used to investigate environmental limits and predict the probability of podoconiosis occurrence. PRINCIPAL FINDINGS Data were available for 141,238 individuals from 1,442 communities in 775 districts from all nine regional states and two city administrations of Ethiopia. In 41.9% of surveyed districts no cases of podoconiosis were identified, with all districts in Affar, Dire Dawa, Somali and Gambella regional states lacking the disease. The disease was most common, with lymphoedema positivity rate exceeding 5%, in the central highlands of Ethiopia, in Amhara, Oromia and Southern Nations, Nationalities and Peoples regional states. BRT modelling indicated that the probability of podoconiosis occurrence increased with increasing altitude, precipitation and silt fraction of soil and decreased with population density and clay content. Based on the BRT model, we estimate that in 2010, 34.9 (95% confidence interval [CI]: 20.2-51.7) million people (i.e. 43.8%; 95% CI: 25.3-64.8% of Ethiopia's national population) lived in areas environmentally suitable for the occurrence of podoconiosis. CONCLUSIONS Podoconiosis is more widespread in Ethiopia than previously estimated, but occurs in distinct geographical regions that are tied to identifiable environmental factors. The resultant maps can be used to guide programme planning and implementation and estimate disease burden in Ethiopia. This work provides a framework with which the geographical limits of podoconiosis could be delineated at a continental scale

Methodological advances in the analysis, assessment and intervention of industrial landscapes

We are currently witnessing a gradual extension of the concept of heritage. This idea has evolved to encompass landscapes and is even reaching into an area which, until recently, had not received sufficient attention: industrial heritage. This new notion of what constitutes heritage is particularly interesting from a cultural perspective, with the appearance of the term “cultural landscape” which covers landscapes produced by industrial decay, among other things. This extended concept of heritage, which is gradually growing both quantitatively and qualitatively, has not only added extra complexity to the limits of what is considered heritage, but is also bringing an evolution in the methodological parameters used for analysis, protection and action, from a 19th-Century modern scientific perspective towards a more epistemological, ideological, political, cultural and technical approach. The object of this paper is to study and analyze the theoretical principles and developments made at international level in relation to environmental research, from the second half of the 20th century to the present day. More specifically, we will focus on the methodologies which seek to overcome the obsolescent tools and methods used in landscape analysis. For this purpose, we will pay particular attention to the methodologies that go beyond considering landscapes as mere visual phenomena, to treat them as an intimate and complex relationship between people and a place. The British methodology Landscape Character Assessment will have a special place in this study. However, this interest in LCA does not mean that we will be ignoring other major methodological contributions. This method review will ultimately enable us to define the basic supporting pillars for the development of a specific methodology to be used in the analysis and intervention of industrial landscapes produced by industrial decay.Universidad de Málaga.

Enhancing rural road policy: the case for the incorporation of the capabilities approach into rural road appraisal in Africa

Infrastructure provisions, especially rural roads, have been highlighted in a number of recent studies and reports as an enabling factor for Africa to achieve 'development'. This paper reviews the current limits of rural road knowledge and appraisal procedures raising critical issues about what is actually known about the impact of rural roads and the extent to which current appraisal methods are able to fully contribute to this debate. An expanded methodology incorporating the capability approach is advocated to help overcome these issues. It is argued here that incorporation of the capability approach may help overcome certain frustrations in our ability to understand the manner in which rural roads impact upon the lives of people. The suggestion is made that the capability approach offers a different angle of analysis that could further contribute to critical questions surrounding the provision of roads, enhancing appraisal and helping to avoid the creation of further infrastructural 'white elephants' that have plagued Africa. Provision of rural roads is after all quite expensive and without a valid appraisal mechanism, money spent on some rural roads may more constructively be utilised elsewhere either on other roads, or on other sectors.

Democratic dialogue and collective learning in the context of self-managed teams

This paper provides a longitudinal, empirical view of the multifaceted and reciprocal processes of organizational learning in a context of self-managed teams. Organizational learning is seen as a social construction between people and actions in a work setting. The notion of learning as situated (Brown & Duguid 1989, Lave& Wenger 1991, Gherardi & al. 1998, Easterby-Smith & Araujo 1999, Abma 2003) opens up the possibility for placing the focus of research on learning in the community rather than in individual learning processes. Further, in studying processes in their social context, we cannot avoid taking power relations into consideration (Contu & Willmott 2003). The study is based on an action research with a methodology close to the ‘democratic dialogue’ presented by Gustavsen (2001). This gives a ground for research into how the learning discourse developed in the case study organization over a period of 5 years, during which time the company abandoned a middle management level of hierarchy and the teams had to figure out how to work as self-managed units. This paper discusses the (re)construction of power relations and its role in organizational learning. Power relations are discussed both in vertical and horizontal work relations. A special emphasis is placed on the dialectic between managerial aims and the space for reflection on the side of employees. I argue that learning is crucial in the search for the limits for empowerment and that these limits are negotiated both in actions and speech. This study unfolds a purpose-oriented learning process, constructing an open dialogue, and describes a favourable context for creative, knowledge building communities.organizational learning; self-managed teams

Does context really collapse in social media interaction?

'Context collapse' (CC) refers to the phenomenon widely debated in social media research, where various audiences convene around single communicative acts in new networked publics, causing confusion and anxiety among social media users. The notion of CC is a key one in the reimagination of social life as a consequence of the mediation technologies we associate with the Web 2.0. CC is undertheorized, and in this paper we intend not to rebuke it but to explore its limits. We do so by shifting the analytical focus from "online communication" in general to specific forms of social action performed, not by predefined "group" members, but by actors engaging in emerging kinds of sharedness based on existing norms of interaction. This approach is a radical choice for action rather than actor, reaching back to symbolic interactionism and beyond to Mead, Strauss and other interactionist sociologists, and inspired by contemporary linguistic ethnography and interactional sociolinguistics, notably the work of Rampton and the Goodwins. We apply this approach to an extraordinarily complex Facebook discussion among Polish people residing in The Netherlands - a set of data that could instantly be selected as a likely site for context collapse. We shall analyze fragments in detail, showing how, in spite of the complications intrinsic to such online, profoundly mediated and oddly 'placed' interaction events, participants appear capable of 'normal' modes of interaction and participant selection. In fact, the 'networked publics' rarely seem to occur in practice, and contexts do not collapse but expand continuously without causing major issues for contextualization. The analysis will offer a vocabulary and methodology for addressing the complexities of the largest new social space on earth: the space of online culture

Intention to use mobile customer relationship management systems

© Emerald Group Publishing Limited. Purpose - The purpose of this paper is to investigate the behavioral intentions of business-to-business (B2B) sales managers to use mobile customer relationship management (CRM) systems in the course of their day-to-day activities. Design/methodology/approach - An extended Technology Acceptance Model (TAM) of mobile CRM system adoption is developed and tested with data from 105 international sales managers representing five B2B companies. Findings - The study extends the TAM framework with three additional constructs derived from mobile technology and sales force automation literature, namely personal innovativeness in the domain of IT, perceived risk, and perceived reachability. The model demonstrates that personal innovativeness and perceived reachability have significant effects on the TAM framework. Research limitations/implications - The relatively small sample size limits the generalization of the results. Practical implications - Sales managers' intention to adopt mobile CRM can be explained by the extended TAM framework. Understanding the key factors that influence intention to adopt a mobile CRM system will aid companies in implementing it among their sales force. Companies willing to foster adoption of a mobile CRM system among the sales force could focus on communicating the usefulness of using the system and benefits gained from enhanced reachability. Recruiting sales people with strong personal innovativeness is beneficial. Originality/value - This study responds the calls for studies on mobile platforms and on the use of mobile B2B applications in sales force management. It is among the first attempts to incorporate variables derived from mobile technology acceptance literature among the sales force into the TAM framework, to better explain acceptance of mobile CRM systems

The power and vulnerability of the ‘new professional’: Web management in UK universities

Research paper Purpose: To explore the character of an emergent occupational role, that of university web manager. Design/methodology/approach: The primary data used were 15 semi-structured interviews conducted in 2004. These were analysed partly for factual and attitudinal data, but also for the discursive interpretative repertoires in use. Findings: The paper examines the diverse backgrounds, occupational trajectories, organisational positions, job roles and status of practitioners working in ‘web management’ in UK Higher Education. The discursive divide between the marketing and IT approaches to the web is investigated. Two case studies explore further the complexity and creativity involved in individuals’ construction of coherent and successful occupational identities. Research implications / limitations: The paper examines the position of web managers within the framework of the notions of the marginal but powerful ‘new professional’ or ‘broker’ technician. It gives a vivid insight into how the web as a dynamic and open technology opens up opportunities for new forms of expertise; but also explores the potential vulnerabilities of such new roles. In order to examine personal experience in depth, data was gathered for only a relatively small number of individuals. The research was also limited to the UK university sector and to those with a broad responsibility for the web site of the whole institution, i.e. not library web managers and other web authors who work primarily to produce a departmental web presence. These limits imply obvious ways in which the research could be extended. Practical implications: There are implications for how institutions support people in such roles, and for how they can support each other. Originality: There is a vast literature about the web, little about the new work roles that have grown up around it

Theatre Practice and Social Adjustment in Nigeria

Current global stress has pushed both individual and social systems to limits. A plethora of schema has been tried for effective adjustment, particularly in Nigeria. `Most times the structures of adjustments are either untried processes or failed praxis from the western mileaux. Therefore, there is the renewed interest in exploring local institutions, resources and managers as contribution to the process of development based on local resources and cost saving production based on the aspirations of the people. The methodology employed is heuristic in providing a framework for utilizing local alternatives in the pursuit of national development. The modest recommendation is that local processes are rational and possess the right capabilities to sustain improvement in quality life in Nigeria.Key words: Theatre, Practice, Social, Adjustmen

The Representation of Queer Teen Identities in Sex Education (Netflix, 2019-)

This article provides an analysis of the representation of LGBTIQ+ teen identities in the first two seasons of ‘Sex Education’ (Netflix, 2019-). Utilising a methodology of analysis anchored in Queer Theory and in the concept of intersectionality, we will study the construction of those characters whose gender expression and/or sexual orientation defy the limits established by cisheteronormativity, as well as those whose desires (whether straight or not) do not fit within what Western societies understand as «normal», since we consider the rejection of the norm as a constitutive element of queerness. The main objectives are a.) to determine which images, knowledge and epistemological constructions regarding sexogenic diversity are disseminated by the show; and b.) to define which discourses are articulated regarding queer (non)identities and the violence suffered by LGBTIQ+ people
