Promotion and Protection of the Rights of the Children in Street Situations in Bankok, Thailand

Wandee, Siripan January 2013 (has links)
This thesis aims at describing how the Convention on the Rights of the Child (CRC) is reflected in the overall operation of the Non-Governmental Organizations and government agencies working with children in street situations in Bangkok, Thailand. It describes children in different street situations in Bangkok; intervention approaches and working methods of the agencies that provide the services for them as well as similarities and differences in each group of the children. As the CRC sets a framework for interventions concerning children, it was interesting to explore whether the practitioners in Bangkok apply the convention in their interventions. This is a descriptive research applying the qualitative data collection methods by which literature review was conducted and semi-structure interviews were carried out according to a written interview guide with professionals represented NGOs and government agencies who directly work with children in street situations, followed by a deductive content analysis of the transcribed interview texts. The field observations were conducted in different areas of Bangkok in order to understand the working environments of the organizations and the conditions of the children. The findings revealfour groups of children in street situations in Bangkok with one being migrants. Their dwelling areas are determined by its socio-economic activities while the livelihoods of each group of children are different. In order to respond to their situations and promote as well as protect their rights, the NGOs and government agencies coordinate in a Network for Street Children in responding to their situations through a Street Teacher Approach. They conduct street/community outreach and responsive actions aiming at protecting, advocating for rights to education, eliminating child labor exploitation, being their significant other,facilitating durable repatriation for migrant children in street situations etc. The rights concept is universal but the childhood concept is culturally relative. The actors in Bangkok bridge the two concepts by taking the situation and the best interest of the child into consideration: they prioritize the child’s well-being which entails rights protection and promotion.

Towards effective implementation of children's rights in Tanzania: lessons and opportunities from Ghana and South Africa

Jonas, Benjamin January 2006 (has links)
"Despite the adoption and wide ratification of the CRC and ACRWC, the miseries identified and intended to be dealt with by the two instruments are still rampant in many parts of the globe. Tanzania, as will be clearly shown in chapter three of this study, is not an exception in this regard. ... Tanzania has ratified both the CRC and ACRWC without reservations. In relation to international law, Tanzania follows a dualist approach. Despite the fact that Tanzania has ratified the two instruments to date, it does not have a specific comprehensive law on children's rights. That notwithstanding, various laws have been enacted, other amended and several programs put in place to protect children from exploitation, and safeguarding their interests. However, these measures have not yielded any feasible results since their adoption. There are still cases of discrimination in respect of girls, children born out of wedlock, non-fulfilment of the principle of best intersts of the child, socio-economic difficulties threatening children's right to life, survival and development of the child; police brutality against street children, the increasing number of children deprived of a family environment, especially AIDS orphans, and an increase in the incidence of child prostitution, early marriages, and various cultural practices which are harmful to children. This study necessitates investigation of the mechanisms which could be adopted, to assist in the successful implementation of children's rights in Tanzania. ... This study, therefore, draws inspirations from the laws and practices on children's rights in Ghana and South Africa and explores the most effective mode of implementation that can ensure the translation of the noble intentions in the two instruments into genuine effective tools for enhancing the well-being of the children in Tanzania." -- Introduction. / Thesis (LLM (Human Rights and Democratisation in Africa)) -- University of Pretoria, 2006. / Prepared under the supervision of Ms. Christine Dowuona-Hammond at the Faculty of Law, University of Ghana, Legon / http://www.chr.up.ac.za/academic_pro/llm1/dissertations.html / Centre for Human Rights / LLM

Optimisation of proteomics techniques for archival tumour blocks of a South African cohort of colorectal cancer

Rossouw, Sophia Catherine January 2020 (has links)
Philosophiae Doctor - PhD / Tumour-specific protein markers are usually present at elevated concentrations in patient biopsy tissue; therefore tumour tissue is an ideal biological material for studying cancer proteomics and biomarker discovery studies. To understand and elucidate cancer pathogenesis and its mechanisms at the molecular level, the collection and characterisation of a large number of individual patient tissue cohorts are required. Since most pathology institutes routinely preserve biopsy tissues by standardised methods of formalin fixation and paraffin embedment, these archived, FFPE tissues are important collections of pathology material, often accompanied by important metadata, such as patient medical history and treatments. FFPE tissue blocks are conveniently stored under ambient conditions for decades, while retaining cellular morphology due to the modifications induced by formalin. / 2022

The future of captured CO2 : Analysis of the role of carbon capture, storage and utilisation in a sustainable Europe

Granér, Oscar, Johansson, Daniel January 2022 (has links)
The energy transition is one of the largest challenges our global society is facing. In 2015, the United Nations acknowledged the Paris Agreement, where the world’s nations were united to limit the global warming well below 2 °C in comparison with pre-historic levels. One of the measures to tackle this challenge that have been proposed by both the International Energy Agency and the European Union is carbon capture and storage or utilisation (CCUS). The concept of CCUS is relatively old but has in light of climate mitigation measures been identified as vital since carbon dioxide (CO2) either can be permanently stored or sequestered into products and materials. Previous research has shown a large potential in CCUS, and that it has a key role in enabling and achieving net-zero climate scenarios. However, large-scale and widely distributed CCUS facilities has not yet been deployed, and it is not fully clear which aspects that are the most important affecting the deployment and how this can be facilitated. This study aims to investigate the current and future market of captured CO2 in Europe during the next decade. The study aims to fill the knowledge gap on how policies affect the development of CCUS, the drivers and barriers that current actors have identified within the field, and lastly, possible pathways in which CO2 can be used. This study was performed using a literature scoping review and interviews with relevant CCUS actors in different parts of the value-chain. The results show CCUS is recognised as an important tool within the European Union to reach the climate goals set out by the European Commission. The development and further deployment of CCUS are however prevented due to economic and legislative barriers, of which low carbon pricing, such as the EU ETS, is identified as the main barrier against making CCUS commercially competitive. Additional legislative barriers are connected to the cross-national trade and export of CO2, as well as a lacking framework on verification and monitoring of captured CO2 and the trade with carbon removal credits. The results also show that CCUS initially will be developed at industrial clusters in the North-West Europe, where shared infrastructure is recognised as an enabler due to sharing risks of investments. The main focus within Europe is on offshore storage rather than CCU due to its large sequestering potential, although CCU can be relevant in regions lacking infrastructure for the transportation of CO2. Regarding the investigated utilisation options, synthetic fuels, building materials, and polymers have been identified to have high potential even if they are not believed to have a high influence as a climate mitigation measure in comparison with CCS. It is concluded that viable business models and cost-effective infrastructure solutions are essential for the European CCUS industry. Much of the deployment is however dependent on clear, beneficial frameworks and policies stating the rules and facilitating the economics of CCUS. Nevertheless, it is expected that especially the European CCS sector will grow in Europe in the upcoming decade, although the role of CCU should not be neglected.

JUVENILE JUSTICE AND THE UN CONVENTION ON THE RIGHTS OF THE CHILD : A Qualitative Content Analysis on the example of the Russian Federation.

Madsen, Diana January 2020 (has links)
This paper analyses the child rights and juvenile justice system in the contemporary Russian Federation as one of the member countries, that adopted the UN Convention on the Rights of the Child 1989. The choice of the researched country is based on the fact, that Russia is one of the few countries in the world, that has adopted a system of juvenile justice and particularly, the juvenile court as an executive juvenile legal authority, that is primarily addressed to the facilitation of child rights and its compliance to the Convention. The paper provides a qualitative content analysis on the juvenile justice and the child rights in Russia, formed in the sequential themes, in which the child rights are compiled and discussed. The results of this paper show how the juvenile justice system is developed in Russia and which advantages/disadvantages it has, as well as what are the new themes in the Russian legislation on the child rights. Therefore, these results are relevant to the field of criminology, in order to conduct future research on the child delinquency, juvenile victimology and other related areas. Thus, an important aspect of this research is to underline a need in the further research in child rights protection, specifically becoming not only as an international obligation, but a national one for all of the countries. The analysis of this paper can serve as the basis for subsequent scientific research and thereby, to contribute to the new solutions of problems associated with the realization of the child rights and their protection. / <p>Madsen, D.

Characterization of a novel EPHB2 R155C mutant with respect to its proteolytic cleavage by TF/FVIIa

Akcan, Ece January 2021 (has links)
EPHB2, an ephrin receptor (EPH) from receptor tyrosine kinase (RTK) family, is one of the substrates for tissue factor (TF) - coagulation factor VIIa (FVIIa) complex and it is cleaved in its ectodomain. EPHB2 cleavage is important for ephrin receptor (EPH) - ephrin ligand (EFN) signaling and cell repulsion. TF has been reported to be overexpressed in different cancer types such as breast and colorectal cancer (CRC). Furthermore, EPHB2 R155C mutation, at the TF/FVIIa-mediated cleavage site, has been identified as one of the somatic mutation sites in human metastatic CRC. Therefore, the aim of the present work was to characterize the EPHB2 R155C mutation and its effect on the cleavage by TF/FVIIa on EPHB2 in context to CRC. We generated overexpression cell models for EPHB2 wild type (wt) and R155C mutant in human CRC DLD-1 cell line for in vitro compartmentalization assay analysis to demonstrate repulsion event in EPH-EFN signaling. Whereas low endogenous TF expression led to incomplete cleavage of EPHB2 wt protein, stable overexpression of TF resulted in complete cleavage. Moreover, overexpression of TF resulted in reduced compartmentalization in EPHB2 wt cells after FVIIa treatment. Transient expression of TF in EPHB2 wt and R155C cells showed no clear difference in EPHB2 cleavage. Interestingly, it was difficult to obtain similar stable overexpression level of TF in EPHB2 R155C cells compared to EPHB2 wt cells. This may lead to further research in context to the role of TF/FVIIa-mediated EPHB2 cleavage in CRC by the generation of TF overexpression cell lines using lentiviral transduction.
