Den här studien undersöker vad som påverkar beslutsfattandet för svenska högskolestudenter ur Generation Z när de gör inköp av kläder, samt vilka konsekvenser det leder till gällande konsumtionen av second hand och fast fashion. Studien undersöker även hur miljömedvetenhet påverkar dessa beslut. Studien är baserad på en enkätundersökning, där frågorna är baserade på teorierna Theory of Planned Behaviour och the Value-Action gap. Med hjälp av enkäten undersöks attityder till olika val samt hur deltagarna agerar. Studien utgår även från tillgänglig litteratur, bestående av vetenskapliga källor och rapporter. Resultaten visar att miljömedvetenhet har en stor inverkan på hur konsumenter agerar, samt att pris, tillgänglighet, kvalitet, storleksutbud och hållbarhet är avgörande när konsumenten fattar sina beslut. En jämförelse mot hållbarhetsmål 12 ur FN:s Agenda 2030, som anses aktuellt för studien, visar på att svenska högskolestudenter ur Generation Z konsumerar förhållandevis hållbart och ligger relativt bra i linje med de uppsatta målen. Resultaten visar även att den generella inställningen till fast fashion är negativ, och inställningen till second hand generellt är positiv. Detta ser lovande ut inför framtiden, och resultaten tyder även på att större medvetenhet kring miljöfrågor leder till mer hållbara val och konsumtionsmönster. / This study examines factors influencing decision-making among Swedish university students from Generation Z when purchasing clothing, as well as the consequences this has on the consumption of second hand and fast fashion. The study also explores how environmental awareness affects these decisions. The study is based on a survey, in which the questions are based on Theory of Planned Behaviour and Value-Action Gap. The survey explores attitudes towards different choices and how participants act. The study also draws from available literature, consisting of scientific sources and reports. The results show that environmental awareness has a significant impact on consumer behaviour, and that price, availability, quality, size range, and sustainability are crucial when consumers make their decisions. The results were compared with several sub-goals of Sustainable Development Goal 12 from the UN's Agenda 2030, which are considered relevant to the study. The results also indicate that the general attitude towards fast fashion is negative, and the attitude towards second hand is generally positive. This looks promising for the future, and the results also suggest that greater awareness of environmental issues leads to more sustainable choices and consumption patterns.

This dissertation focuses on the phenomenon of copper cable theft within the Gauteng Province of South Africa. Data was collected from literature sources as well as from security professionals combating copper theft. There are five primary objectives in this research: 1. To explore and to describe the extent and the impact of copper cable theft. 2. To gain insight into the profile and the modus operandi of the offender. 3. To evaluate current intervention measures used to combat the copper cable theft. 4. To describe the general factors limiting the success of combating copper cable theft. 5. To recommend probable intervention measures with which to combat copper cable theft. Semi-structured interviews were conducted with responsible security officials of victim stakeholder groups in Gauteng. It was established that copper cable theft is currently a very serious crime that deserves both attention and quick intervention before it does irreparable damage to the utility infrastructure of Gauteng, in particular, and in fact to all these infrastructures in South Africa. / Criminology / M.A. (Criminology)

Im naturwissenschaftlichen Unterricht werden Daten z.B. in Erkenntnisgewinnungsprozessen eingesetzt und somit ist hier auch die Evaluation von Daten wichtig. Es können Daten aus erster und zweiter Hand unterschieden werden, wobei die Unterscheidung auf Basis des Autoren und der Beteiligung an der Datenerhebung geschieht. Im Physikunterricht werden Schüler*innen mit Daten aus unterschiedlichen Quellen konfrontiert. Es wird angenommen, dass die Evaluation von Daten durch Schüler*innen als Glaubwürdigkeitsbewertung dieser Daten verstanden werden kann. Ergänzend zur Theorie wurde in einer Studie untersucht, welche Kriterien Schüler*innen bei der Evaluation unterschiedlicher Datensätze verwenden, die sich nur durch den Autor unterschieden. Dafür wurden 17 Interviews mit Schüler*innen durchgeführt (13-16 Jahre). Eine qualitative Inhaltsanalyse führte zu einem Codesystem mit vier Codes und diversen Subcodes. Die Codes bezogen sich auf die Themen Eigenschaften des Experiments, Eigenschaften von Autoren, Eigenschaften der Daten und Prüfen/Abgleichen. Unterschiede in der Verwendung der Kriterien für verschiedene Datentypen, wurden in einer zweiten Studie überprüft. Dazu wurden 42 Interviews mit schüler*innen (14-16 Jahre) durchgeführt. Alle Probanden erzeugten selbstständig physikalische Daten und wählten Hypothesen über den Ausgang des Experiments aus. Im Anschluss wurden sie mit einem von drei verschiedenen Datensätzen konfrontiert: ihren eigenen Daten, den Daten eines anderen Schülers oder Daten eines Lehrers. Das Codesystem war die Grundlage einer quantitativen Inhaltsanalyse dieser Interviews. Diese erlaubte es, Unterschiede zwischen den Versuchsgruppen zu finden. Es ergaben sich keine Unterschiede für das Hypothesenwechselverhalten, die Verwendung von Kriterien für die Glaubwürdigkeitsbewertung oder das Rating der Wichtigkeit der Codes zwischen den Versuchsgruppen. Folgerungen für den Unterricht und die Unterscheidung der Datentypen werden erläutert. / In science education data is used in the process of gaining knowledge and it is therefore important to evaluate the data. First- and second-hand-data can be differentiated, whereby the distinction is based on the authorship and the involvement in the data acquisition. In physics education students are regularly confronted with data from different sources. It is assumed that the evaluation of data by students can be understood as the evaluation of the datas credibility. To complement a theoretical model, an interview study was conducted to find out which criteria for the evaluation of the credibility of data are used by students when evaluating different types of data. 17 students (13-16 years) were interviewed. A qualitative content analysis yielded a systems of four different codes and several subcodes. These codes where representations of statements that dealt with properties of the experiment, properties of the author, properties of the data, and testing and comparing. A second study was conducted to test if there are differences in the use of those criteria when students are confronted with different types of data. 42 Interviews with students (14-16 years) were conducted. All subjects acquired a set of first-hand data in an experiment and where asked to choose between 3 hypotheses about the outcome. Afterwards they were confronted with three different sets of data: their own data, another student's set of data, and a teacher's set of data. The system of codes from the previous study was used as the basis for a quantitative content analyses of these interviews. This analysis made it possible to find differences between the experimental groups. No differences were found for the change of the hypothesis, the use of criteria for the evaluation of credibility or the rating of importance of the codes. Implications for education and the differentiation of types of data are discussed.

Hållbarhet är idag ett välanvänt begrepp som förekommer inom flera områden. Vad hållbarhet anses vara må uppfattas som självklart, men hur begreppet och diskursen konstrueras, är inte lika självklart. Genom att se till två aktörer, med olika ambitioner, inom andrahandsmarknaden undersöker studien hur reklam bidrar till konstruerandet av uppfattandet av hållbarhet på olika sätt. Tidigare forskning visar att medierna formar och speglar samhället och att uttryck av hållbarhet idag används som täckmantel i form av grön retorik. Den visar även att kapitalism och ekologi har naturliga motsättningar, att vi måste konsumera mindre och lära oss se ”skräp” som resurser, något som andrahandsmarknaden kämpar med att förhålla sig till. Vi undersöker i denna studie Tradera och Myrornas förmedlade budskap av hållbarhet, med bakgrund i aktörernas intressen som vinstdrivet och ideellt. Syftet är att se hur reklam inom andrahandsmarknaden bidrar till konstruerandet av hållbarhetsdiskursen. Detta genom en multimodal kritisk diskursanalys av reklamfilmer från respektive aktör.   Resultatet visar att de olika aktörernas förmedlade budskap bidrar till hållbarhetsdiskursen på både traditionella och kreativa sätt. Traderas reklamfilm visade sig uttrycka underliggande budskap av ekologi som dessvärre hamnar i skuggan av kapitalistiska och materialistiska värderingar. Myrornas reklamfilm utmanar på många olika sätt dessa traditionellt kapitalistiska och materialistiska värderingar. Dessa olika uttryck av hållbarhet utgör till viss del konstruerandet av hållbarhetsdiskursen. Det visar även att särskilda budskap kan verka ideologiskt gynnsamma och att detta är något som aktörer utnyttjar. Vi drar slutsatsen att hållbarhetsdiskursen innefattar svårtolkade budskap som samexisterar och problematiserar vår relation till ett hållbart agerande. / Modern use of the term ‘sustainability’ is broad and varies across multiple industries. The general idea of sustainability is perceived as certain, yet sustainability discourse and the pillars of the term remain fluid. By looking at two stakeholders, with different ambitions, within the second hand market, the study is examining how advertising contributes to the different ways sustainability perceptions are constructed. Previous studies show that media both shapes and reflects our society, highlighting today’s use of the term sustainability is often to “green wash” communication. Studies also shows that capitalism and ecology have natural contradictions. Second hand markets face the challenge of raising awareness to change perceptions for society's to consumer less and begin to see “waste” as a resource. In this study we examine the message of sustainability, mediated by Tradera and Myrorna, in relation to their role as profit-driven, versus not for profit organisations. The purpose of the study is to examine how advertisement within the secondhand market, contributes to the construction of sustainability discourse. This is carried out through a multimodal critical discourse analysis of commercials. The results show that the different stakeholders' messages contribute to the sustainability discourse in both traditional and creative ways. Tradera’s advertisement expressed underlying statements of ecology, shadowed by capitalistic and materialistic values. However, Myrorna’s advertisement in many ways challenges these traditional capitalistic and materialistic values. To some extent these different expressions construct the discourse of sustainability. This further highlights that ideologically specific messages could work, however this is often exploited by businesses. The conclusion drawn from this study displays that the sustainability discourse involves messages difficult to interpret, which infers parallels to the convoluted relationship of society’s aim to advance sustainable development.

Portable languages and distributed paradigms have driven a wave of new applications and processing models. One of the most promising, certainly from its early marketing, but disappointing (from its limited uptake)is the mobile agent execution and data processing model. Mobile agents are autonomous programs which can move around a heterogeneous network such as the Internet, crossing through a number of different security domains, and perform some work at each visited destination as partial completion of a mission for their agent user. Despite their promise as a technology and paradigm to drive global electronic services (i.e.any Internet-driven-and-delivered service, not solely e-commerce related activities), their up take on the Internet has been very limited. Chief among the reasons for the paradigm's practical under-achievement is there is no ubiquitous frame work for using Internet mobile agents, and non-trivial security concerns abound for the two major stake holders (mobile agent users and mobile agent platform owners). While both stake holders have security concerns with the dangers of the mobile agent processing model, most investigators in the field are of the opinion that protecting mobile agents from malicious agent platforms is more problematic than protecting agent platforms from malicious mobile agents. Traditional cryptographic mechanisms are not well-suited to counter the bulk of the threats associated with the mobile agent paradigm due to the untrusted hosting of an agent and its intended autonomous, flexible movement and processing. In our investigation, we identified that the large majority of the research undertaken on mobile agent security to date has taken a micro-level perspective. By this we mean research focused solely on either of the two major stakeholders, and even then often only on improving measures to address one security issue dear to the stake holder - for example mobile agent privacy (for agent users) or access control to platform resources (for mobile agent platform owners). We decided to take a more encompassing, higher-level approach in tackling mobile agent security issues. In this endeavour, we developed the beginnings of an infrastructural-approach to not only reduce the security concerns of both major stakeholders, but bring them transparently to a working relationship. Strategic utilisation of both existing distributed system trusted-third parties (TTPs) and novel mobile agent paradigm-specific TTPs are fundamental in the infrastructural framework we have devised. Besides designing an application and language independent frame work for supporting a large-scale Internet mobile agent network, our Mobile Agent Secure Hub Infrastructure (MASHIn) proposal encompasses support for flexible access control to agent platform resources. A reliable means to track the location and processing times of autonomous Internet mobile agents is discussed, withfault-tolerant handling support to work around unexpected processing delays. Secure,highly-effective (incomparison to existing mechanisms) strategies for providing mobile agent privacy, execution integrity, and stake holder confidence scores were devised - all which fit comfortably within the MASHIn framework. We have deliberately considered the interests - withoutbias -of both stake holders when designing our solutions. In relation to mobile agent execution integrity, we devised a new criteria for assessing the robustness of existing execution integrity schemes. Whilst none of the existing schemes analysed met a large number of our desired properties for a robust scheme, we identified that the objectives of Hohl's reference states scheme were most admirable - particularly real - time in - mission execution integrity checking. Subsequently, we revised Hohl's reference states protocols to fit in the MASHIn framework, and were able to overcome not only the two major limitations identified in his scheme, but also meet all of our desired properties for a robust execution integrity scheme (given an acceptable decrease in processing effiency). The MASHIn offers a promising new perspective for future mobile agent security research and indeed a new frame work for enabling safe and autonomous Internet mobile agents. Just as an economy cannot thrive without diligent care given to micro and macro-level issues, we do not see the security prospects of mobile agents (and ultimately the prospects of the mobile agent paradigm) advancing without diligent research on both levels.

À la frontière de l’anthropologie économique et de la sociologie urbaine, cette thèse de doctorat étudie le mode de fonctionnement et l’impact de la filière transnationale d’exportation de véhicules d’occasion sur l’un de ses principaux axes :la route commerciale reliant Bruxelles à Cotonou.<p>La première partie de la thèse propose une description minutieuse des différentes étapes suivies par les véhicules le long de la filière commerciale ainsi qu’une typologie des acteurs de l’activité. Cette description est notamment l’occasion d’une discussion critique des couples d’analyse formel/informel, légal/illégal habituellement mobilisés pour décrire ce type d’activité commerciale.<p>La seconde partie de la thèse est centrée sur la dimension spatiale de l’activité. L’approche est construite autour du concept de place marchande entendu comme un outil économique essentiel dans la « production » de la marchandise véhicule d’occasion. Pour que les nombreuses voitures rendues disponibles en Europe puissent être transformées en biens consommables, et mises en relation avec la demande africaine, il est nécessaire qu’elles soient rassemblées en un marché. C’est cette fonction que la place marchande parvient à remplir en combinant les impératifs d’éclatement et de concentration.<p>La troisième et dernière partie de la thèse est consacrée aux acteurs de l’activité. En particulier aux importateurs de véhicules qui incarnent la dimension transnationale de la filière commerciale. C’est dans la comparaison entre importateurs béninois et libanais que s’est construite l’analyse des pratiques économiques et du profil migratoire de ces importateurs. / Doctorat en Sciences politiques et sociales / info:eu-repo/semantics/nonPublished

English, Zulu and Northern Sotho summaries / This study aims to evaluate the Non-Ferrous Metals Crime Combating Committee's impact on combating copper cable theft in South Africa. Data was collected via in-depth interviews with awaiting trial detainees charged with copper cable theft at the Pollsmoor Correctional Centre in the Western Cape; members of the Mpumalanga and Gauteng Provincial Non-Ferrous Metals Crime Combating Committee; members of Business Against Crime South Africa; and investigators attached to Combined Private Investigations who investigate copper theft nationally. The in-depth interviews provided a comprehensive understanding of participant experiences relating to the impact of the Non-Ferrous Metals Crime Combating Committee on the combating of copper cable theft in South Africa. Moreover, the researcher performed a thorough literature study of the phenomenon locally and internationally. Research findings indicate shortcomings in the Non-Ferrous Metals Crime Combating Committee's effectiveness, limiting its impact on preventing copper cable theft. Based on these findings, the study recommends that the Non-Ferrous Metals Crime Combating Committee be replaced with a specialised South African Police Service Non-Ferrous Metals Theft Unit. Consequently, this study puts forward a set of recommendations proposing a systematic pro-active plan to address and minimise copper cable theft in South Africa. The proposed plan convincingly presents practical solutions to minimise copper cable theft and contributes to the current body of scholarship on copper cable theft in South Africa. / Inhloso yalolu cwaningo ukuhlola umthelela wohlelo lwe-Non-Ferrous Metals Crime Combating Committee mayelana nokuqedwa kokutshontshwa kwentambo yogesi (copper cable).
