Syftet med den föreliggande studien är att undersöka bevekelsegrunder till att ungdomaranvänder cannabis och vad användningen av cannabis i ung ålder kan få för effekter påungdomarnas psykosociala hälsa och utveckling. Syftet är även att undersöka på vilket sätt enlegalisering eller avkriminalisering av icke-medicinsk cannabis påverkar ungdomarsanvändning av, och inställning till, cannabis i de länder/stater där legalisering har genomförts.Studien har tre ledande frågeställningar: (1) att undersöka vilka faktorer som är särskiltframträdande för att motivera ungdomar att använda respektive avstå från cannabis, (2) attkartlägga vilka framträdande positiva- och negativa effekter cannabisanvändning i tidig ålderhar – i termer av psykosocial hälsa och utveckling, samt slutligen (3) undersöka ifall det finnsnågra skillnader i ungdomars cannabisanvändning samt inställning till cannabis innan,respektive efter, genomförandet av en legalisering/avkriminalisering – och på vilket sätt dessaskillnader i så fall kan förklaras. Studien har utformats som en integrativ litteraturöversikt ivilken både kvalitativa- och kvantitativa data har inkluderats för att besvara studiens syfte ochfrågeställningar. I resultatet blottläggs ett flertal bevekelsegrunder till att ungdomar använder,eller avstår från, cannabis. Dessa bevekelsegrunder kan summeras i tre övergripande teman:Avkoppling, tidsfördriv eller umgänge, omgivningens inställningar till cannabis samtsjälvmedicinering för välbefinnande. Resultatet visar att användningen av cannabis i ung ålderkan relateras till flera effekter för ungdomens psykosociala hälsa och utveckling, såsom psykiskohälsa i form av depression, självmordstankar, en högre risk att utveckla psykosliknandetillstånd och svårigheter att klara av skolan. Användningen kan samtidigt upplevas lindrandeav psykisk problematik och självskadebeteende samt leda till ökad kreativitet och medvetenhet.Därutöver visar resultatet att en legalisering och avkriminalisering av cannabis irekreationssyfte inte har någon signifikant påverkan på ungdomars användning av cannabis påkort sikt. Däremot finns ett samband mellan amerikanska legaliseringslagar för cannabis ochökande antal cannabisrelaterade sjukhusinläggningar bland ungdomar i flera amerikanskadelstater, speciellt i stater med legalisering av icke-medicinsk cannabis, vilket tyder på enförändring i ungdomars cannabisvanor. Vidare påvisar resultatet att legaliseringen, i deamerikanska stater där en legalisering genomförts, har bidragit till en ökad exponering förcannabisreklam i form av reklamannonser och skyltar vilket bidragit till en normalisering avcannabis. Slutligen diskuteras och analyseras studiens resultat utifrån studiens centrala begrepp,tidigare forskning och studiens teoretiska ramverk. / The following study aims to investigate the motives for adolescent cannabis use and in whatway cannabis use at a young age can affect the psychosocial health and development. Inaddition, the study intends to investigate in what way a legalization or decriminalization of nonmedicalcannabis affects young people's use of, and attitude towards, cannabis in the countries/ states where legalization has been implemented. The study has the major focal points: (1) toexamine which factors are prominent in motivating adolescents to use, or abstain, fromcannabis, (2) to identify the prominent positive and negative effects of cannabis use at an earlyage – in terms of psychosocial health and development, (3) to examine whether there are anydifferences in adolescent cannabis use and attitudes towards cannabis before, or after, theimplementation of a legalization/decriminalization – and in what way these differences can beexplained. The study is designed as an integrative literature review in which both qualitativeand quantitative data have been included to answer the study’s purpose and questions. Theresult of the study shows several factors who are prominent in motivating adolescent cannabisuse, such as recreational purposes, the attitudes of the social environment and self-medicationfor well-being. The results shows that the use of cannabis at a young age can be related toseveral psychosocial effects such as depression, suicidal thoughts, a higher risk of developingpsychosis-like conditions and school dropouts. The use of cannabis can also alleviate mentalproblems and self-harming behaviour and lead to increased creativity and awareness. Inaddition, the results show that the legalization and decriminalization of cannabis for recreationalpurposes has no significant impact on adolescent cannabis use in the short term. However, thereis a link between US cannabis legalization laws and the growing number of cannabis-relatedhospitalizations among adolescents in several US states, especially in states with legalizationof non-medical cannabis, indicating a change in adolescents' cannabis habits. Furthermore, theresults show that the legalization, in the US states where a legalization has been carried out, hascontributed to an increased exposure to cannabis advertising, which has contributed to anormalization of cannabis use. Finally, the results of the study are discussed and analysed basedon the key concepts, previous research, and the theoretical framework of the study.

Low Impact Development (LID) is a sustainable stormwater management approach that aims to control runoff close to its source, mimicking the natural hydrological processes such as infiltration and storage. It is being adopted by many cities, where its implementation is rapidly evolving. The LID practices are small-scale measures; therefore, they need to be widely implemented to impact significantly. The selection of LIDs depends on the land use and characteristics of the area of interest. This study focuses on residential LIDs. First, a systematic and bibliometric literature review is conducted on the residential LIDs articles published up to the year 2020; a total of 94 papers were found in the Web of Science. This review resulted that LID implementation in residential areas still needs to be investigated. To assist the City, engineers, and policy-makers in implementing the suitable LIDs for detached houses, a multi-criteria decision analysis framework incorporating a hydrological model is developed in this study. The commonly used LIDs were identified, which are rain gardens, permeable pavement, rain barrels, soakaways. Seven criteria were selected – runoff depth reduction rate, peak runoff reduction rate, installation cost, maintenance cost, retrofit cost, life cycle, and aesthetical view. For the properties of the single-detached house and LIDs, the standards of Credit Valley Conservation (CVC) and Toronto and Region Conservation Authority (TRCA) were followed. The proposed decision-making framework also was applied to a case study. This framework is still in the preliminary stage, thus holds the potential to convert into a tool that will be handy enough for the homeowners and consume less time. / Thesis / Master of Applied Science (MASc)

Within the last decade research on climate change strategies and adaptive capacity emerged as the debate about climate change was intensified with the publishing of the Third Assessment Report by the Intergovernmental Panel on Climate Change in 2001. That companies are facing risks and opportunities is not new and the awareness to address these issues is growing. However, there is still need for research in the field of corporate strategic response to climate change. Recently, research focused on resilience management to address climate change. Resilience management is about being able to experience changes and remain stable getting back into the same situation before the change happen. On the contrary to resilience management adaptive capacity is about the ability to be able to adapt to uncertain and unexpected events on the long term. This includes long-term changes. This work argues that companies should think about their adaptive capacity as climate change induces short and long-term changes. Adding this dimension to the strategic planning companies need to think of how they can improve their adaptive capacity. This work investigates research in both issues adaptive capacity and climate change research and in their relation. Applying a systematic literature review this study conducted 60 references which are examined by a qualitative-quantitative analysis and answers the following questions: What is the current scientific view of adaptive capacity within strategic management literature? What are determinants of adaptive capacity? How can adaptive capacity be linked to climate change strategy and is it even antecedent to climate change strategies? The findings of this research indicate that adaptive capacity and climate change strategies exhibit a link but it cannot be proved whether adaptive capacity is antecedent. Furthermore, the term adaptive capacity is merely discussed within strategic management literature and if it is discussed and examined, several concepts and theories are applied to explain determinants of adaptive capacity. Several concepts such as dynamic capabilities, organizational learning capability, organizational learning, organizational change capacity, flexibility and more could be identified as concepts enhancing adaptive capacity. This works provides an overview of related concepts and theories.

[pt] As organizações que atuam em resposta a desastres buscam cada vez mais a eficiência na realização dos seus processos para que, assim, possam ser capazes de atender o maior número possível de pessoas afetadas. Neste sentido, o objetivo principal deste trabalho é propor um modelo de maturidade para avaliar operações de desastres e identificar estratégias que permitam a evolução da maturidade. Para este fim, a pesquisa é fundamentada em uma revisão sistemática da literatura, que identificou oito modelos para gestão de operações de desastres, e um estudo de caso. Com base na revisão sistemática da literatura é proposto o Modelo de Maturidade para Processos de Desastres. Como primeira validação, um estudo de caso foi conduzido na Defesa Civil do Estado do Rio de Janeiro, Brasil para avaliar a maturidade das operações de resposta em três situações distintas: Geral (Situação 1), um tipo de desastre recorrente na região - as inundações do norte e noroeste fluminense (Situação 2), e um desastre não recorrente - a pandemia de COVID-19 (Situação 3). Constatou-se que para as três situações analisadas a organização apresentou maturidade final igual a 4 (Aurora) com sinais de evolução para o estágio máximo (Apogeu). Além disso, por ser um tipo de desastre recorrente, o desastre da Situação 2 apresentou maiores semelhanças na realização dos processos de resposta a desastres comparados com a Situação Geral (1). / [en] Disaster response organizations are increasingly looking for efficiency in carrying out their processes so that they can be able to serve as many affected people as possible. In this sense, the main objective of this work is to propose a maturity model to assessment of disaster operations and identify strategies that allow the evolution of maturity. To this end, the research based on a systematic literature review, which identified eight models for disaster operations management, and a case study. The Maturity Model for Disaster Processes was proposed based on the systematic literature review. As a first validation, a case study was conducted at the Civil Defense of the State of Rio de Janeiro, Brazil to assess the maturity of the response operations. Three different situations in this case study were analyzed: General (Situation 1), a recurring disaster type in the region - the floods in the north and northwest of Rio de Janeiro (Situation 2), and a non-recurring disaster - the COVID-19 pandemic (Situation 3). It was found that, the organization reached final maturity stage 4 (Aurora) for the three situations analyzed, with signs of evolution to the maximum stage (Zenith). Also, as it is recurrent disaster type, disaster of the Situation 2 showed more significant similarities in carrying out disaster response processes compared to the General Situation (1).

[pt] As cadeias de suprimento (CS) estão sendo cada vez mais pressionadas a implementar iniciativas para tornar o seu desempenho mais sustentável. Como exemplo, pode-se citar os desafios impostos pela transição energética para o setor de óleo e gás e suas CS. Orientar a CS em direção a sustentabilidade requer um esforço coordenado, integrado e colaborativo entre os múltiplos parceiros. Um fator crucial para evoluir a trajetória de sustentabilidade das CS é a aprendizagem que ocorre durante a implementação das iniciativas de sustentabilidade colaborativas. Entretanto, não há evidências suficientes na literatura sobre como e em que níveis o processo de aprendizagem ocorre, assim como, sobre suas características e forma de interação entre os parceiros. O objetivo da tese é aprofundar o entendimento sobre as características da dinâmica de aprendizagem e sua influência na trajetória de sustentabilidade nas CS. A tese utiliza os métodos de revisão sistemática da literatura e estudo de caso múltiplo. Como resultados principais, apresenta uma tipologia e framework teórico integrado sobre aprendizagem de sustentabilidade em CS e propõe uma abordagem baseada em processo para investigação empírica do fenômeno. A pesquisa foi conduzida em três grandes multinacionais internacionais e em suas CS atuantes no Brasil. Os resultados mostram que a trajetória de sustentabilidade da CS é cumulativa, recorrente e não-linear, resultante de sucessivas oportunidades de aprendizado emergentes das iniciativas de sustentabilidade colaborativas na CS. Valendo-se do raciocínio abdutivo, a tese fornece um primeiro passo na elaboração de teoria de sobre aprendizagem de sustentabilidade da CS e cunha o conceito de plasticidade da CS. / [en] Supply chains (CS) are pressured to implement initiatives to make their performance more sustainable. For example, the challenges imposed by the energy transition for the oil and gas sector and its SC stand out. Guide SC towards sustainability requires a coordinated, integrated, and collaborative effort between multiple partners. A crucial factor in evolving the sustainability trajectory of SC is the learning that takes place during the implementation of collaborative sustainability initiatives. However, there is not enough evidence in the literature about how and at what levels the learning process occurs, as well as about its characteristics and form of interaction between partners. The objective of the thesis is to deepen the understanding of the characteristics of the learning dynamics and their influence on the sustainability trajectory in the SC. The thesis uses the methods of systematic literature review and multiple case studies. As the main results, it presents a typology and integrated theoretical framework on SC sustainability learning and proposes a process-based approach for empirical investigation of the phenomenon. The research was conducted in three large international multinationals and in their SC operating in Brazil. The results show that SC s sustainability trajectory is cumulative, recurrent, and non-linear, resulting from successive learning opportunities emerging from collaborative sustainability initiatives at SC. Adopting abductive reasoning, the thesis provides a first step in the elaboration of a theory of learning about SC sustainability and coined the concept of SC plasticity.

DevSecOps emerged to mitigate the challenges of integrating security into DevOps. DevOps have grown tremendously, leading to difficulties in integrating security tools in its development process while maintaining speed and agility. This study aims to investigate the security tools in DevSecOps and how they have been reported in previous literature. The main objective of this study is to provide a knowledge base concerning security tools in DevSecOps that can be used to mitigate challenges regarding the selection and use of security tools in the context of DevSecOps. A systematic literature review was adopted for the research. The study collected a total of  228 studies published between 2015 and 2022; fourteen of these papers were selected to be used for data extraction after conducting a thorough review protocol. This study has identified thirteen security tool categories used or recommended to be used in DevSecOps. These tools have been structured into seven phases of the development process and five security practices. Additionally, this study has identified twelve drawbacks and sixteen recommendations concerning the use of these security tools in DevSecOps.  The security tools categories, recommendations, and drawbacks identified in this study could potentially be used to facilitate the challenges of selecting and using security tools in DevSecOps and similar methodologies that rely on automation and delivering software frequently.

[pt] O gerenciamento de riscos é um dos tópicos de pesquisa mais atraentes dentro do campo da gestão da cadeia de suprimentos. Devido à crescente diversidade e à extensão das cadeias, as questões ambientais tornaram-se hoje um tópico de pesquisa desafiador dentro deste contexto. Além disso, os recentes escândalos ambientais trazem à tona a negligência acerca das questões ambientais por parte de grandes empresas. O presente estudo explora, portanto, a gestão de riscos ambientais na cadeia de suprimentos. Para isso, foi realizada, inicialmente, uma revisão sistemática da literatura a fim de identificar os riscos ambientais presentes nas cadeias de suprimentos de uma empresa, a reação dos stakeholders perante esses riscos, que se desdobram em consequências para as empresas, bem como as estratégias ambientais para mitigação dos riscos. São identificados quatorze riscos ambientais, três principais consequências e dezenove estratégias que se relacionam através de um framework proposto. Posteriormente, um múltiplo estudo de caso é conduzido em três empresas situadas no Brasil, com a finalidade de verificar a relação das variáveis identificadas na literatura com as realidades organizacionais. Constata-se que a maioria dos riscos e estratégias ambientais advindas da revisão da literatura é também observada nas empresas estudadas e, dentre as consequências, as mais citadas pelas organizações são perdas reputacionais e financeiras. A partir dos estudos de casos, é possível complementar e validar os estudos acadêmicos existentes, endossando, assim, a discussão sobre o gerenciamento de riscos ambientais na cadeia de suprimentos. / [en] Risk management in supply chains has emerged as one of the most attractive research topics in the supply chain management field. Due to increasing diversity and the growing size of supply chains, environmental issues have today become a challenging research topic in supply chain risk management. Besides that, the recent environmental accidents bring to light the neglect of environmental issues by large companies. Thus, the present study explores the environmental risk management in supply chains. For this, a systematic literature review is carried out in order to identify the environmental risks present in the supply chain of a company, the reaction of the stakeholders to these risks, which unfold as consequences for the companies, as well as the strategies for mitigating these risks. It is identified fourteen environmental risks, three main consequences and nineteen strategies that are related by a proposed framework. Subsequently, a multiple case study is conducted in three companies located in Brazil, with the purpose of verifying the relationship of the variables identified in the literature with the organizational realities. It is verified that most of the risks and environmental strategies coming from the academic literature are observed by the companies and, among the consequences, the most cited ones are related to the company s reputation and financial consequences. From the cases studies, it is possible to complement and validate the existing academic studies, in order to endorse the discussion about environmental risk management in the supply chain.

Professional development (PD) of teachers is part of the Department of Basic Education‘s (DBE) initiative to encourage school communities to use of information and communication technology (ICT) to improve the quality of Mathematics teaching and learning. The South African Council of Educators stipulates that PD programmes should align with system-wide needs, strengthen learning area content and outcomes, and promote system transformation. Imbedded in this system-wide criterion is The White Paper on e-Education to employ a fully ICT integrated system at all levels of education: management, teaching and learning, and administration by 2013. Mathematics teachers require PD that develops their technological pedagogical and content knowledge (TPACK) and their social professional identity (SPI). The PD of Mathematics teachers for ICT integration can assist the DBE to achieve the aims of The White Paper on e-Education and bridge the technology gap between South Africa and international education systems. Open distance learning (ODL) could be a viable method to deliver PD to Mathematics teachers to address their zone of proximal development, develop their TPACK, and establish and maintain their SPI. This study made use of a fully mixed sequential equal status multi-mode research design and methodologies to develop guidelines for the PD of Mathematics teachers in the pedagogical use of ICT in ODL. The qualitative phase (Phase I) was rooted in the interpretivist paradigm. Through an adjustable exploration of a systematic literature review, the researcher identified 23 core documents, analysed them with Atlas.ti™, and conceptualised four themes according to Engeström‘s third generation activity theory (AT). Phase II (radical exploration phase) of the research design was rooted in the radical structuralist paradigm. In the context of transformation, it developed, validated, and standardised a research instrument for the measurement of Mathematics teachers‘ PD requirements. The instrument was distributed to 300 senior phase (grades 7-9) Mathematics teachers in eight education management district centres of the WCED. The analyses of the quantitative data conceptualised a fifth activity system. The five activity systems from the adjustable and radical exploration phases were symbiotic, and co-dependent. Expansive learning was used for boundary crossing and network building during six phases of this study. The findings from the six phases of the expansive learning cycle indicated that PD of Mathematics teachers in ODL for Phase III implementation of the e-Education policy should be a joint initiative. Fundamentally ICT integration and implementation should start with Department of Basic Education (DBE) initiatives. The DBE and Provincial Departments of Education (PDEs) should conduct a needs analysis of ICT implementation, evaluate previous ICT PD programmes, plan ICT PD strategies aligned with the ICT development plan, as well as with the requirements of the Mathematics teachers. The DBE and PDE should invest in the provision of ICT equipment, afford human capital, reinstate the laptop initiative for teachers, and supply schools with networked-computer facilities to explore online platforms for PD. Mathematics teachers should assess their professional knowledge to construct new philosophies, create a subject network group, and interact as participants and members within their social environments. The standardised instrument could be used to determine and compare the PD of Mathematics teachers in other provinces and contexts. / PhD (Training and development), North-West University, Potchefstroom Campus, 2014
