The female perspective on a situation of uncertainty

Climate change impacts are becoming more severe globally, with estimations of a continued negative trend in the future. This interacts with increasing natural disasters as well as non-climatic stressors, such as pandemics or social stressors, creating a multi-exposure to stressors especially harmful for rural populations and small-scale farmers who depend on natural resources for their livelihoods. Men and women are impacted differently by stressors and face different opportunities to respond, which relates to gendered social roles. The multi-exposure to stressors, and interaction of them, may also have accumulated effects. Therefore, this thesis examines how women experience and navigate exposure to multiple enivronmental and other stressors over time, and what the accumulated effect of continued exposure to it is on women during their life trajectories. Nepal is a country that has experienced multiple different overlapping stressors in recent years, such as climate change, the 2015 Gorkha earthquake, high levels of food insecurity, significant out-migration and the COVID-19 pandemic. For this reason, it provides an opportunity for examining how multiple stressors intersect long-term within a household and how it impacts women’s daily lives. Through a case study, the thesis builds on semi-structured interviews combined with other participatory rural appraisal methods. For a deeper understanding of how social structures and biophysical factors shape how women in rural Nepal experience and navigate multiple stressors over time, the analysis builds on the concept of vulnerability. Vulnerability refers to the susceptibility of being harmed by an event and is in this study conceptualized as contextual, gendered and with a cumulative effect. The empirical findings show that not all women experience a stressor in the same way, however, there is a common feeling of women being more impacted, feeling more concerned and facing a heavier burden than men. Stressors lead to increased time and labor for women in the responsibilities they have, such as domestic work, agricultural work and childcare. It also shows how women greatly worry about food, safety and health of the family when experiencing different types of stressors. These aspects all relate to social structures and gender roles, affecting women’s daily lives, experienced impacts and responses. The gender roles also mean they lack voice and decision-making power. Multi-exposure to stressors is found to lead to an increased emotional stress for women. Through highlighting life histories, the study shows how vulnerability is personally experienced and that interaction between multiple stressors over time shapes women’s long-term prospects for lives they value. While women are found to be restricted in their gender roles, there are also demonstrated ways in which women come together and organize themselves. This indicates that changes may be happening and that gender does not only mean differentiated vulnerability. Shared gender can also be a source of strength and solidarity in times of stress

Long walk to press freedom: the media framing of the April 2015 xenophobic attacks in South Africa

This thesis enquires into the collective violence against foreigners in South Africa in April 2015. The aim of the study is to investigate the manner in which the media framed the attacks, and to analyse how both victims and perpetrators were presented in news articles. The research process utilised in this study is qualitative content analysis, and the study analyses 68 articles by six online news publications between the 13th and the 21st of April 2015. The thesis determines that the Daily Sun, News24, Independent Online (IOL News), Eyewitness News (EWN), Mail & Guardian, and the Daily Maverick presented both balanced and biased content between the 13th and 21st of April 2015. There was a great variety in how objectively the online news publications framed immigrants. Several online news publications included numerous sources and counter-arguments, while others did not. The Mail & Guardian and the Daily Maverick presented the most in-depth coverage of the violence, while the Daily Sun, News24, Independent Online (IOL News), and Eyewitness News (EWN) uncritically reproduced xenophobic language and statements during the attacks

The Importance of Authentic Workplace-Based Assessment: A Study From VET Teacher Education

Context: This article is based on a pragmatic theoretical perspective on education, in which theoretical and practical competences are developed through experiences and participation in real-world teaching contexts. Previous research points to a lack of culture for authentic workplace-based assessment in vocational and professional education in many countries. Prior to this study, professors/authors and student-teachers in a vocational teacher education program in Norway experienced that student-teachers were unable to demonstrate comprehensive teaching competence, as examinations and assessments assess theoretical knowledge separately from practice. Research questions: 1) How can an authentic workplace-based exam during placement give student-teachers an opportunity to showcase their comprehensive teacher competence? 2) What factors are important to emphasize in such an exam? 3) How do the student-teachers demonstrate and develop comprehensive teacher competence through an authentic exam?Methods: Using action research, professors/authors carried out sequential actions to develop a practical-theoretical exam in an authentic professional setting. This included demonstrating elements of practical and theoretical competence conducted during teaching practice. The exam involved planning in line with a guidance document and practical teaching in the classroom in VET-schools, followed by a piece of reflective writing based on teaching experiences. Supervisors and professors/authors observed the student-teachers teaching as part of multiple qualitative methods.Findings: The empirical results show how student-teachers demonstrate and develop comprehensive teaching competence. Both the student-teacher and the supervisors in VET-schools experienced the authentic exam as realistic and professionally based. The biggest challenge involved logistics: Compensating the professors’/authors’ time and financial frameworks related to the observation of the student-teachers. However, this kind of authentic assessment leads to stronger coherence between both theory and practice, and between the vocational teacher education at the university and the VET in upper secondary school. It also supports the job-relevant learning process towards comprehensive teacher competence.Conclusions: This kind of authentic assessment i.e. an authentic exam requires an understanding of the complex role of teachers within their professional context in VET. Therefore, the professors/authors see the need of a broader, more comprehensive teacher competence in VET to meet the work life needs for competence.

Auditory icon support for navigation in speech-only interfaces for room-based design metaphors

Proceedings of the 9th International Conference on Auditory Display (ICAD), Boston, MA, July 7-9, 2003.In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs. The users' subjective attitudes toward auditory icons were significantly more positive than to earcons

Differential expression of Axl and Gas6 in renal cell carcinoma reflecting tumor advancement and survival

PURPOSE: Overexpression of the receptor tyrosine kinase Axl is implicated in several cancers. Therefore, we conducted this study to determine the expression of Axl and its ligand Gas6 in various renal cell carcinoma (RCC) types and in oncocytoma. EXPERIMENTAL DESIGN: Real-time quantitative reverse transcription-PCR was used to quantify tumor mRNA levels for Axl and Gas6 in a cohort (n = 221) of RCC patients. Serum levels of soluble sAxl and Gas6 proteins were measured using specific ELISA assays (n = 282). The presence of Axl protein in tumor tissue was evaluated by immunohistochemistry (n = 294). Results were correlated to tumor-associated variables, clinical biochemical tests, and patient survival. RESULTS: Tumor Axl mRNA levels correlated independently to survival when assessed against tumor stage and grade. In the study group, the median cancer-specific survival of all RCC patients during 307 months of follow-up was 55 months (confidence interval, +/-40.4). The 25% of patients with lowest tumor Axl mRNA levels had significantly better survival than the rest (P = 0.0005), with 70% of the patients still alive at the end of follow-up. In contrast, in patients with medium-high Axl mRNA, only 25% were alive at the end of follow-up. Tumor Gas6 mRNA levels correlated to survival, tumor-associated variables, and disease severity as did serum levels of soluble sAxl and Gas6 protein. However, no correlation between Axl protein in tumor tissue and survival was found. CONCLUSIONS: Axl and Gas6 expression in RCC are associated with tumor advancement and patient survival. In particular, low tumor Axl mRNA levels independently correlated with improved survival

Analysis of Ozone (O3) and Erythemal UV (EUV) measured by TOMS in the equatorial African belt

We presented time series of total ozone column amounts (TOCAs) and erythemal UV (EUV) doses derived from measurements by TOMS (Total Ozone Mapping Spectrometer) instruments on board the Nimbus-7 (N7) and the Earth Probe (EP) satellites for three locations within the equatorial African belt for the period 1979 to 2000. The locations were Dar-es-Salaam (6.8° S, 39.26° E) in Tanzania, Kampala (0.19° N, 32.34° E) in Uganda, and Serrekunda (13.28° N, 16.34° W) in Gambia. Equatorial Africa has high levels of UV radiation, and because ozone shields UV radiation from reaching the Earth’s surface, there is a need to monitor TOCAs and EUV doses. In this paper we investigated the trend of TOCAs and EUV doses, the effects of annual and solar cycles on TOCAs, as well as the link between lightning and ozone production in the equatorial African belt. We also compared clear-sky simulated EUV doses with the corresponding EUV doses derived from TOMS measurements. The TOCAs were found to vary in the ranges 243 DU − 289 DU, 231 DU − 286 DU, and 236 DU − 296 DU, with mean values of 266.9 DU, 260.9 DU, and 267.8 DU for Dar-es-Salaam, Kampala and Serrekunda, respectively. Daily TOCA time series indicated that Kampala had the lowest TOCA values, which we attributed to the altitude effect. There were two annual ozone peaks in Dar-es-Salaam and Kampala, and one annual ozone peak in Serrekunda. The yearly TOCA averages showed an oscillation within a five-year period. We also found that the EUV doses were stable at all three locations for the period 1979−2000, and that Kampala and Dar-es-Salaam were mostly cloudy throughout the year, whereas Serrekunda was mostly free from clouds. It was also found that clouds were among the major factors determining the level of EUV reaching the Earth´s surface. Finally, we noted that during rainy seasons, horizontal advection effects augmented by lightning activity may be responsible for enhanced ozone production in the tropics.publishedVersio

Mapping cells and sub-cellular organelles on 2-D gels: ‘new tricks for an old horse’

AbstractNowadays, investigators in all fields are faced with the identification of unknown, up- or down-regulated, modified proteins that they are trying to identify. Two-dimensional (2-D) gel electrophoresis, with its ability to resolve several thousand proteins, is an extremely powerful technique. The current resolution and reproducibility of 2-D gel technology and the establishment of computer assisted 2-D gel protein databases have paved new ways for the identification of proteins

Effects of atmospheric sphericity on stratospheric chemistry and dynamics over Antarctica

Atmospheric sphericity is an important factor that must be considered in order to evaluate an accurate ozone loss rate in the polar stratosphere. The built-in plane-parallel radiative transfer scheme of a nudging chemical transport model (CTM) and an atmospheric general circulation model (AGCM) with coupled chemistry is modified by a pseudospherical approximation. The plane-parallel atmosphere radiative transfer version (PPA version) is compared with the pseudospherical atmosphere radiative transfer version (SA version) for both the nudging CTM and AGCM. The nudging CTM can isolate the chemical effects for a given dynamical field, while the interaction among the chemical, radiative, and dynamical processes can be studied with the AGCM. The present analysis focuses on Antarctica during an ozone hole period. In the ozone loss period over Antarctica, ozone starts to decrease earlier and minimum value of total ozone becomes lower in the SA versions of both the nudging CTM and the AGCM than in the corresponding PPA versions. The ozone mixing ratio decreases earlier in the SA version because of an earlier increase of ClO concentration initiated by the upward actinic flux at solar zenith angles greater than 90°. Dynamics plays an important role as well as the chemical processes. During the ozone recovery period, the ozone distribution becomes almost the same in the SA and PPA versions of the nudging CTM, while in the AGCM the ozone amount in the SA version remains at lower values compared to those of the PPA version. In the AGCM, a decrease of ozone over Antarctica enhances the latitudinal gradient of temperature and thus strengthens the polar vortex in the SA version. A resultant delay of the polar vortex breakup causes the delay of the ozone recovery. For the AGCM, ensemble runs are performed. The ensemble experiment exhibits large ozone variances after the middle of December, when the ozone recovery is dynamically controlled. Most ensemble members of the AGCM show a delay of the polar vortex breakup in the SA version, while a few members show opposite results. In the latter members, the polar vortex breakup is strongly affected by the enhanced EP flux from the troposphere around 100 hPa, which causes the variances in the ozone recovery period. Most members, however, do not show large statistical variances; that justifies the conclusions from the ensemble means
