Socialarbetare som arbetar i Turkiet beskrivs uppleva dilemman som ständigt påverkar deras arbete. Trots detta förekommer begränsad internationell och nationell forskning som undersöker turkiska socialarbetares upplevelser av arbetet. Tidigare forskningsstudier har redovisat att socialarbetare i Turkiet upplever att de internationella arbetsvärderingarna innehåller förtryck och orättvisor samtidigt som arbetet i sig beskrivs bidra med känslomässig utmattning och osäkerhet. De etiska dilemman som turkiska socialarbetare beskrivs uppleva anses vara omfattande, däremot förekommer begränsad information om förhållningssättet gentemot de etiska riktlinjerna i arbetet. Denna kvalitativa studie syftar därmed till att undersöka turkiska socialarbetares upplevelser av arbetet och dess förhållningssätt gentemot IFSWs globala etiska riktlinjer. Studien bygger på nio semistrukturerade intervjuer med socialarbetare i Turkiet varpå ett subjektivt perspektiv har varit en central aspekt. Studiens resultat visar att socialarbetare i Turkiet upplever en brist på riktlinjer och regler i arbetet vilket har resulterat i en känsla av osäkerhet och begränsat handlingsutrymme. De befintliga insatserna beskrivs även vara så pass otillräckliga att de har kommit att påverka socialarbetarna på en subjektiv nivå. Vidare beskrivs orättvisa förhållanden förekomma inom landet vilket påverkar arbetets prioriteringar och arbetarnas möjligheter till en påverkan på arbetet. Slutligen framkommer det att det inte förekommer några etiska riktlinjer inom arbetet eller någon form av kännedom om IFSWs globala etiska riktlinjer, trots att Turkiet utgörs av ett medlemsland i IFSW. / Turkish social workers are to a greater extent described to be experiencing dilemmas that are affecting their quality of work. Despite the circumstances, there is an insufficient amount of research on a national and international level that subjectively examines the Turkish social workers' experiences in the workspace. Previous research has shown that social workers in Turkey believe the international work values contain elements of oppression and injustice while the duty is described as a contributing factor to increased exhaustion and uncertainty. The ethical dilemmas Turkish social workers are faced with can be regarded as extensive, albeit there is insufficient knowledge regarding the method of approach towards the ethical guidelines for social workers. The purpose of this qualitative study is to examine Turkish social workers' experiences within their line of work and their approach towards the IFSW global ethical guidelines. The study is based on nine semi-structured interviews with social workers in Turkey, where a subjective perspective regarding their experiences has been a central aspect. This study finds that social workers in Turkey experience a lack of guidelines and rules within their line of work which contributes to an increased uncertainty amongst the social workers, thus also limiting their capacity for action. The existing efforts are described as being inadequate to the point where it has affected the social workers quality of work to a subjective degree. Furthermore, there is an overall consensus that occurrences of unfair conditions are not a rare sight in the country. This affects the social workers priorities and possibilities of having an influence in their work. Finally, it emerges that no standardized ethical guidelines are being followed, nor is there any knowledge of the IFSW global ethical guidelines despite the fact that Turkey is a member state of IFSW.

The field of modelling and processing of 'images' has fairly recently become important, even crucial, to areas of science, medicine, and engineering. The inevitable explosion of imaging modalities and approaches stemming from this fact has become a rich source of mathematical applications. <br /><br /> 'Imaging' is quite broad, and suffers somewhat from this broadness. The general question of 'what is an image?' or perhaps 'what is a natural image?' turns out to be difficult to address. To make real headway one may need to strongly constrain the class of images being considered, as will be done in part of this thesis. On the other hand there are general principles that can guide research in many areas. One such principle considered is the assertion that (classes of) images have multiscale relationships, whether at a pixel level, between features, or other variants. There are both practical (in terms of computational complexity) and more philosophical reasons (mimicking the human visual system, for example) that suggest looking at such methods. Looking at scaling relationships may also have the advantage of opening a problem up to many mathematical tools. <br /><br /> This thesis will detail two investigations into multiscale relationships, in quite different areas. One will involve Iterated Function Systems (IFS), and the other a stochastic approach to reconstruction of binary images (binary phase descriptions of porous media). The use of IFS in this context, which has often been called 'fractal image coding', has been primarily viewed as an image compression technique. We will re-visit this approach, proposing it as a more general tool. Some study of the implications of that idea will be presented, along with applications inferred by the results. In the area of reconstruction of binary porous media, a novel, multiscale, hierarchical annealing approach is proposed and investigated.

This thesis deals with The International Code of Ethics of Social Work. The first part focuses on the origins, history, updates and criticism of ethical codes. It is followed by the analysis of various principles of the International Code of Ethics. This analysis was based on the scientific literature of social work and the articles published in the Czech Republic. Subsequently, for each principle the results of the research among social workers in the South Region were processed. They reveal how social workers perceive the different principles. The analysis is concluded with a brief insight into the ethical theories.
