Field geographies

Philosophy section,A decade of innovative Geography (Article 689).Epistemological discourses such as those that have emerged from women’s studies (particularly feminism) and development studies have, however, shown geographers that there is a need to challenge the power assumptions embedded in the whole process of research, including methodological choices that can include or exclude. By tracing these discourses and using examples from these two disciplines, this article demonstrates how contemporary geography has taken on board some of the new methodological approaches that have thus transpired. In turn, this has enriched geographical enquiry, which is now, much as the subject itself, seen as a social construct requiring critical reflection and challenge

Enhancing online climate change education: distance and conventional university collaboration for a Master's curriculum

See also a longer version: ‘Expanding Citizen and Practitioner Engagement with the Climate Change Challenge Through Collaborative Masters Curriculum, Open Educational Resources, E-learning Communities and Virtual Mobility’, presented at a conference of European Association of Distance Teaching Universities (EDTU), Zermatt, Switzerland, September 2010 (www.eadtu.nl/.../Accepted%20Presentations%20for%20Newsletter.pd).This paper analyses the different ways in which both distance and conventional universities engage with learning and teaching. It argues that rather than seeing their roles as institutionally compartmentalised, there is much benefit in delivering online education through an institutional collaboration which develops synergies with a potential to contribute to citizen and professional practitioner empowerment, in this case, for debates about climate change. The example the paper draws on is that of a European Region Action Scheme for the Mobility of University Students (Erasmus) project ‘The Lived experience of climate change (LECH-e): interdisciplinary e-module development and virtual mobility’. The project brings together five distance and three conventional universities across six EU countries, plus the European Association of Distance Teaching Universities (EADTU), to create a Master’s curriculum in the area of climate change. It argues that universities across Europe have complementary strengths, both in terms of their disciplinary expertise and the ways in which they engage with students. Understanding the complex, real-world challenge of climate change requires a holistic approach which draws on these complementary strengths through collaborative work.

Women's home-based income generation as a strategy towards poverty survival : dynamics of the 'khannawalli' (mealmaking) activity of Bombay

For generations. the "khannawallis" have supplied daily cooked meals for thousands of single male migrant textile workers who live in appalling conditions in Bombay. In this way. they have become essential to Bombay's industrial development and daily functioning. However. the activity remains "invisible" and very little notice is taken of the women or their work. This thesis uses the khannawalli activity as a case study to understand the dynamics and problematics of women's home-based income generation. By exploring the Marxist and the feminist discourse on the "informal" sector; women; and poverty. the thesis comes to the conclusion that the best way of analyse the khannawalli activity is by adopting a "livelihoods system" approach. In doing so. it suggests that women's home-based income activities are better understood as strategies towards survival. rather than small entrepreneurial activities. Understood in this way, the central point of analysis becomes the access each individual has to the resources and opportunities necessary to start and maintain an activity. An analysis based on access is able to draw out social differentiation between individual operators and their operations. It also enables a comment on individual relationships. both within the household and outside of it. Altogether. this develops an understanding of how women's home-based income activities operate. and what problems they create. Furthermore, by setting the activity within a historical context. this case study is also able to look at recent changes that have affected the khannawalli activity. Whilst some of these changes have been detrimental to the activity, the khannawallis have proved that it is possible. even for those in the "informal" sector to address their future by organising themselves. The khannawallis show that women in poverty are not simply the passive recipients of their destiny

Dimensions of professional competences for interventions towards sustainability

This paper investigates sustainability competences through the eyes of professional practitioners in the field of sustainability and presents empirical data that have been created using an action research approach. The design of the study consists of two workshops, in which professional practitioners in interaction with each other and the facilitators are invited to explore and reflect on the specific knowledge, skills, attitudes and behaviours necessary to conduct change processes successfully towards sustainability in a variety of business and professional contexts. The research focuses on the competences associated with these change processes to devise, propose and conduct appropriate interventions that address sustainability issues. Labelled ‘intervention competence’, this ability comprises an interlocking set of knowledge, skills, attitudes and behaviours that include: appreciating the importance of (trying to) reaching decisions or interventions; being able to learn from lived experience of practice and to connect such learning to one’s own scientific knowledge; being able to engage in political-strategic thinking, deliberations and actions, related to different perspectives; the ability for showing goal-oriented, adequate action; adopting and communicating ethical practices during the intervention process; being able to cope with the degree of complexity, and finally being able to translate stakeholder diversity into collectively produced interventions (actions) towards sustainability. Moreover, this competence has to be practised in contexts of competing values, non-technical interests and power relations. The article concludes with recommendations for future research and practice

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Insecticide resistance status in Anopheles gambiae in southern Benin

BACKGROUND: The emergence of pyrethroid resistance in Anopheles gambiae has become a serious concern to the future success of malaria control. In Benin, the National Malaria Control Programme has recently planned to scaling up long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) for malaria prevention. It is, therefore, crucial to monitor the level and type of insecticide resistance in An. gambiae, particularly in southern Benin where reduced efficacy of insecticide-treated nets (ITNs) and IRS has previously been reported. METHODS: The protocol was based on mosquito collection during both dry and rainy seasons across forty districts selected in southern Benin. Bioassay were performed on adults collected from the field to assess the susceptibility of malaria vectors to insecticide-impregnated papers (permethrin 0.75%, delthamethrin 0.05%, DDT 4%, and bendiocarb 0.1%) following WHOPES guidelines. The species within An. gambiae complex, molecular form and presence of kdr and ace-1 mutations were determined by PCR. RESULTS: Strong resistance to permethrin and DDT was found in An. gambiae populations from southern Benin, except in Aglangandan where mosquitoes were fully susceptible (mortality 100%) to all insecticides tested. PCR showed the presence of two sub-species of An. gambiae, namely An. gambiae s.s, and Anopheles melas, with a predominance for An. gambiae s.s (98%). The molecular M form of An. gambiae was predominant in southern Benin (97%). The kdr mutation was detected in all districts at various frequency (1% to 95%) whereas the Ace-1 mutation was found at a very low frequency (<or= 5%). CONCLUSION: This study showed a widespread resistance to permethrin in An. gambiae populations from southern Benin, with a significant increase of kdr frequency compared to what was observed previously in Benin. The low frequency of Ace-1 recorded in all populations is encouraging for the use of bendiocarb as an alternative insecticide to pyrethroids for IRS in Benin

The use of calcium hydroxide, antibiotics and biocides as antimicrobial medicaments in endodontics

Bacteria have been implicated in the pathogenesis and progression of pulp and periapical diseases. The primary aim of endodontic treatment is to remove as many bacteria as possible from the root canal system and then to create an environment in which any remaining organisms cannot survive. This can only be achieved through the use of a combination of aseptic treatment techniques, chemomechanical preparation of the root canal, antimicrobial irrigating solutions and intracanal medicaments. The choice of which intracanal medicament to use is dependent on having an accurate diagnosis of the condition being treated, as well as a thorough knowledge of the type of organisms likely to be involved and. their mechanisms of growth and survival. Since the disease is likely to have been caused by the presence of bacteria within the root canal, the use of an antimicrobial agent is essential. Many medicaments have been used in an attempt to achieve the above aims, but no single preparation has been found to be completely predictable or effective. Commonly used medicaments include calcium hydroxide, antibiotics; non-phenolic biocides, phenolic biocides and iodine compounds. Each has advantages and disadvantages, and further research is required to determine which is best suited for root canal infections
