Safeguarding the right to adequate food in disaster preparedness and emergency response: Policy, legislation and institutions in Uganda
No full textMaster i samfunnsernæringThe rising frequency of natural disasters has impacts for the nutrition situation in Uganda. As State Party to the international Covenant on Economic, Social and Cultural Rights, the Government of Uganda is obliged to progressively realize the human right to adequate food (RtF) for all Ugandan citizens.
This study is an analysis of the recognition of the RtF in Uganda’s policy-, legislative- and institutional frameworks for disaster preparedness and emergency response (DPER). The study design was cross-sectional and descriptive; the approach qualitative, and data was collected through document analysis, literature reviews and semi-structured interviews with purposively selected duty bearers. Data analysis included the use of indicators, real-time- and content analysis, coding, patterning and statistical analysis for descriptive purposes.
The failure to construct, adopt and implement vital plans and laws that would contribute to the realization of the RtF in the context of DPER is linked to the complexity of the DPER- system, as well as the weak recognition of international human rights obligations among key duty bearers. Safeguarding the RtF in disaster planning and management is a prerequisite for fighting malnutrition in Uganda, and needs to be made a national priorit

Normalized Weighting Schemes for Image Interpolation Algorithms
No full textImage interpolation algorithms pervade many modern image processing and
analysis applications. However, when their weighting schemes inefficiently
generate very unrealistic estimates, they may negatively affect the performance
of the end user applications. Therefore, in this work, the author introduced
four weighting schemes based on some geometric shapes for digital image
interpolation operations. And, the quantity used to express the extent of each
shape weight was the normalized area, especially when the sums of areas
exceeded a unit square size. The introduced four weighting schemes are based on
the minimum side based diameter (MD) of a regular tetragon, hypotenuse based
radius (HR), the virtual pixel length based height for the area of the triangle
(AT), and the virtual pixel length for hypotenuse based radius for the area of
the circle (AC). At the smaller scaling ratio, the image interpolation
algorithm based on the HR scheme scored the highest at 66.6 % among non
traditional image interpolation algorithms presented. But, at the higher
scaling ratio, the AC scheme based image interpolation algorithm scored the
highest at 66.6 % among non traditional algorithms presented and, here, its
image interpolation quality was generally superior or comparable to the quality
of images interpolated by both non traditional and traditional algorithms.Comment: 17 pages, 15 figures, 2 Table
Evaluation of Extra Pixel Interpolation with Mask Processing for Medical Image Segmentation with Deep Learning
No full textCurrent mask processing operations rely on interpolation algorithms that do not produce extra pixels, such as nearest neighbor (NN) interpolation, as opposed to algorithms that do produce extra pixels, like bicubic (BIC) or bilinear (BIL) interpolation. In our previous study, the author proposed an alternative approach to NN-based mask processing and evaluated its effects on deep learning training outcomes. In this study, the author evaluated the effects of both BIC-based image and mask processing and BIC-and-NN-based image and mask processing versus NN-based image and mask processing. The evaluation revealed that the BIC-BIC model/network was an 8.9578 % (with image size 256 x 256) and a 1.0496 % (with image size 384 x 384) increase of the NN-NN network compared to the NN-BIC network which was an 8.3127 % (with image size 256 x 256) and a 0.2887 % (with image size 384 x 384) increase of the NN-NN network.5 pages, 10 figure, 7 table
Understanding the impact of polymer functionalized electrode fabrication and cycling conditions on stability and selective separation of micropollutants
No full textThe main focus of this thesis is on selectively separating target contaminants present in an aqueous environment via electrochemically-mediated capture at polymer interfaces in order to improve water security. Heavy metal pollutants such as arsenic have diverse physico-chemical properties which renders them intractable in current treatment technologies such as wastewater treatment plants (WWTPs). These pollutants are able to pass through WWTPs and end up in the aquatic environment becoming a threat to ecosystems or end up in drinking water. Electrochemically mediated selective capture of the heavy metal pollutants is a promising technology but current methods lack molecular selectivity are unstable and have difficulty separating the target ion without producing toxic byproducts. Polymer coated electrodes comprised of poly(vinyl) ferrocne (PVF) and 3-ferrocenylpropyl acrylamide (PFPMAm) have been developed to selectively separate arsenic due to their electronic tunability, fast electron transfer, redox processes at moderate potentials below that of water splitting, and molecular level recognition of target pollutants of concern. Properties of the resulting redox polymer electrode were also investigated using various analytical instruments.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2023-05-01The student, Emmanuel Kayiwa, accepted the attached license on 2021-04-30 at 13:36.The student, Emmanuel Kayiwa, submitted this Thesis for approval on 2021-04-30 at 13:55.This Thesis was approved for publication on 2021-04-30 at 14:02.DSpace SAF Submission Ingestion Package generated from Vireo submission #16630 on 2021-09-16 at 20:14:47Made available in DSpace on 2021-09-17T04:06:57Z (GMT).

Food security and income through sweet potato production in Teso, Uganda
No full text146 - 155 p.Two relevant studies on food security are referred to in the article. Food insecurity from time to time threatens in Teso sub region which houses a viable Teso agricultural system. One study was done during 2001-2003 in Teso on sweet potato production with 650 persons participating and the second one was done in one disaster affected area of Bududa District nearby during 2012-2016 when 1,142 persons participated. Kiryandongo District where Bududa landslide survivors were resettled in Uganda was included in that study. Participatory methods such as focus group discussions, farm observations, in-depth interviews, and questionnaires were used. Both studies used qualitative and quantitative methods for data analysis. The sweet potato stands second after cassava as the crop for famine and disaster periods in Teso to meet the human right to adequate food to complement the well dried cereals & grain legumes that stored longer. Livestock especially was also one of the prime determinants of food security and income in Teso. Free from cyanides with a good content of affordable Vitamin A from orange fleshed varieties, sweet potatoes in Teso contributed about 61% to the yearly food per capita of the population thus a recommendable crop for sustainable food security and some income in Teso and beyond
The Impact of Privacy Laws on Everyday Life in Switzerland: A Social Perspective
No full textThis thesis explores the impact of privacy laws on everyday digital life in Switzerland from a social perspective, with a particular focus on the relationship between digital rights, public awareness, and personal empowerment. In a society where digital interactions are omnipresent and data collection is increasingly pervasive, understanding the societal role and reception of privacy regulations such as the Swiss Federal Act on Data Protection (FADP) and the European GDPR is more important than ever.
The aim of this research is to assess how individuals perceive, understand, and interact with privacy laws, and to identify whether these laws effectively support digital sovereignty at both governmental and personal levels. The study also investigates the extent to which the general population feels equipped to exercise control over their digital presence and data.
The theoretical framework introduces the core concepts of privacy, data protection, digital literacy, trust in digital systems, and digital sovereignty. These notions are contextualized within current literature and examined through a sociotechnical lens, with references to scholars such as Zuboff and Fratini, who highlight the growing tension between individual autonomy and corporate or governmental data control.
In the empirical part, the author combines a quantitative survey targeting the general population with a qualitative interview conducted with a cybersecurity expert in the financial sector. The survey investigates levels of awareness, behavior, and attitudes related to privacy rights and digital sovereignty, while the expert interview provides insights into the practical challenges and ethical considerations of implementing data protection in a heavily regulated industry.
The results indicate a significant gap between legal provisions and public understanding. While privacy is widely valued in theory, there is limited practical engagement with legal rights and digital tools. Trust in institutions and major tech platforms is fragile, and many respondents express the need for clearer information and more accessible means to protect their data.
Based on these findings, the thesis proposes several improvements: integrating digital rights into education, simplifying access to data rights, promoting privacy friendly alternatives, and fostering collaboration between public institutions, academia, and civil society. These suggestions are aimed at reducing the disconnect between regulation and lived experience, and at strengthening both individual and collective digital sovereignty.
The reliability and validity of the research are considered through its methodological design and mixed methods approach. The study contributes to the broader discourse on digital citizenship by highlighting the importance of social understanding and engagement in the successful implementation of privacy legislation

UTILIZATION OF ANTENATAL CARE SERVICES AMONG REFUGEE TEENAGE MOTHERS AT NAKIVALE REFUGEE SETTLEMENT IN WESTERN UGANDA. A PHENOMENOLOGICAL STUDY.
No full textIntroduction:
Antenatal care is crucial for positive pregnancy outcomes and is dependent on the timing and quality of care. It promotes health education and helps identify and manage maternal complications and risk factors. In Sub-Saharan Africa, pregnancy complications and childbirth are the leading cause of death for women aged 10-19. This study examined teenage mothers' experiences and perceptions of accessing and utilizing antenatal care services in the Nakivale refugee settlement, Isingiro district.
Methodology:
A phenomenological study was conducted on teenage mothers in Nakivale, using a snowball sampling method. Key informant interviews were conducted, lasting 45 minutes -1 hour. Ethical clearance was obtained from Bishop Stuart University REC and informed consent was obtained from participants. Data was analyzed thematically using Nvivo version 12.
Results:
Teenage mothers face challenges utilizing antenatal care services including negative treatment from family and community members. However, positive feelings of responsibility alleviate stress, making early mothers more resilient.
Conclusions:
Access to ANC services is closely linked to its utilization, but societal discrimination against teenage mothers affects ANC utilization. Teenage-friendly spaces in Nakivale significantly influenced access and utilization of ANC services.
Recommendations:
The study suggests establishing customized ANC services for teenage mothers in the Nakivale refugee settlement, Isingiro district, to enhance access and utilization of ANC
