The changing climate is a major driver for transitioning towards a Circular Economy (CE). However, conceptual discussions and business models related to CE are still emerging, thus considered to be inadequate and immature. One way to promote and accelerate a CE is through shifting towards Circular procurement (CP). Additionally, one major change needed for procurement in order to become circular, regards the assurance of follow-up and control of products and materials. However, there is limited research on CP in terms of collaboration and follow-up activities. Thus, this study explores how collaboration between an organization, its suppliers and customers can be strategically handled to support follow-up and control of products and materials within CP.  The chosen methodology consisted of a qualitative research design with an exploratory approach. A total of eleven semi-structured interviews were conducted. Derived from the theoretical findings coupled with empirical findings, a framework was developed to clearly map out the challenges related to CP, activities needed in procurement when transitioning to a CP as well as the potential outcomes of these. To ensure the relevance of the activities included in the developed framework, three out of the total eleven interviews were conducted with experts within the circular field, to validate the framework. In terms of the findings of this research, several important aspects related to how collaboration can promote integration of circularity within procurement to ensure follow-up and control of products and material were found. Firstly, a new type of internal collaboration between sales and the procurement department is needed. Besides this, the procurement function should focus on maintaining a long-term relationship with the suppliers, preferably already contracted ones. Further, due to the lack of knowledge related to the concept of CP, it was found that there is a need to integrate a preparation phase called phase 0 prior to the traditional steps of a procurement process. Finally, it was found that the integration of feedback and monitoring mechanisms, in form of documentation and checklists, is of importance to monitor and evaluate circular targets as well as document the lessons learnt to apply these in upcoming procurement processes. / Det förändrade klimatet är en viktig drivkraft för övergången till en Cirkulär Ekonomi (CE). Konceptuella diskussioner och affärsmodeller relaterade till CE håller fortfarande på att växa fram, och anses därför vara otillräckliga och omogna. Ett sätt att främja och påskynda en CE, är att växla mot cirkulära inköp (CI). En stor förändring som krävs för att inköpsfunktionen ska bli cirkulär, är att säkerställa uppföljning och kontroll av produkter och material. Dock finns det begränsad forskning om CI vad gäller samverkan och uppföljningsaktiviteter. Således undersöker denna studie hur samverkan mellan en organisation, dess leverantörer och kunder kan hanteras strategiskt för att säkerställa uppföljning och kontroll av produkter och material inom CI. Den valda metodiken bestod av en kvalitativ studie med ett utforskande förhållningssätt. Totalt genomfördes elva semi-strukturerade intervjuer. Med utgångspunkt från litteraturgenomgången tillsammans med analysen från insamlade data utvecklades ett ramverk för att tydliggöra utmaningar relaterade till CI, aktiviteter som behövs inom inköpsprocessen vid integration av cirkularitet, samt det potentiella resultatet och påverkan av dessa. För att säkerställa relevansen av aktiviteterna ingående i det utvecklade ramverket, genomfördes tre av de elva intervjuerna med experter som innehar kunskap kring cirkularitet. Syftet med dessa tre intervjuer var huvudsakligen för experterna att validera ramverket. När det gäller resultaten av denna studie hittades flera viktiga aspekter relaterade till hur samverkan kan främja integration av cirkularitet inom inköpsprocessen för att säkerställa uppföljning och kontroll av produkter och material. För det första upptäcktes behovet av en ny intern samverkan mellan sälj och inköpsfunktionen. Utöver ökad kommunikation och samverkan mellan sälj och inköpsfunktionen, bör inköpsfunktionen fokusera på att upprätthålla en långsiktig relation med leverantörer. Vidare, på grund av bristen på kunskap relaterad till begreppet CI, fann man att det finns ett behov av att integrera en förberedelsefas som i denna studie kallas fas 0, före de traditionella stegen i en inköpsprocess. Slutligen fann man att det är viktigt att integrera återkopplings- och uppföljningsmekanismer i form av dokumentation och checklistor, för att kunna övervaka och utvärdera cirkulära mål samt dokumentera lärdomarna för att tillämpa dessa i kommande inköpsprocesser.

Objective: Recent evidence suggests that illness perceptions in paediatric patients and their parents may differ, with parents holding more negative views compared to their children. Little is known about illness perceptions of very young patients and their parents. This study investigates illness perceptions in paediatric cancer patients aged 4–18 years and their parents in acute treatment or follow‐up care, distinguishing patients by age (4–11, 12–18) and stage of medical treatment. - Methods: N = 45 patient–parent dyads in acute treatment and n = 95 dyads in follow‐up care were examined. Parents and older children aged 12–18 years completed the Illness Perception Questionnaire—Revised (IPQ‐R) and younger children aged 4–11 years were examined using an age‐adapted hand puppet interview containing the IPQ‐R questions. Difference scores of illness perceptions (symptoms, timeline‐acute/chronic, timeline‐cyclical, personal control, illness coherence, consequences, emotional representations) between children and parents were tested for significance using Wilcoxon signed‐rank tests. - Results: Overall, parents perceived more symptoms associated with their child's illness/treatment than the children themselves. In acute treatment, younger children indicated more negative and older children more positive views regarding chronicity than parents. Younger children held less negative views on consequences, and all children reported less negative emotional representations than parents. In follow‐up care, all children held less negative views on consequences and emotional representations. Older children reported less negative views on chronicity, cyclicity and illness coherence. - Conclusion: Differences in illness perceptions of paediatric patients and their parents should be considered during and after treatment/medication and psychosocial care to support illness coping in person‐ and family‐centred interventions.

The decentralized and pseudonymous nature of cryptocurrencies like Bitcoin has made it easier for criminal entities to engage in illicit activities online compared to relying on traditional currency systems. Detecting these activities is vital to preventing and combating such abuse. We employ a data collection tool based on a Depth First Search algorithm to follow the largest receivers from 10 illicit starting addresses in each abuse type; Darknet, Blackmail, Tumbler, and Ransomware. The results from our two searches showed that money tends to be concentrated to one or two receivers and that all abuse types rely heavily on so-called Two-Transaction addresses. These addresses are only used once, likely as intermediaries to obfuscate money flow, potentially within the inner layer of Bitcoin Tumblers. The results also showed behaviors within the abuse types that were both consistent with and divergent from existing research. Furthermore, similarities and unique behaviors across the abuse types were identified. Expanding the dataset with deeper searches could yield clearer patterns in money flow behavior. Additionally, increasing the number of data collection points could enhance the analysis. Finally, the starting addresses significantly impacted the trustworthiness and reliability of our results. We hope our findings, lessons, and developed tools will aid future research and the development of strategies to combat online abuse.

No / Transition planning using a person-centred approach has, in the main, failed to shape service provision. We offer an alternative based on an ecological understanding of human development linked to public health approaches that prioritise whole system planning. A total of 43 young people with intellectual disabilities, in Bradford, England, who were approaching transition from school or college were recruited to a qualitative study. Their ethnic breakdown was as follows: 16 white British, 24 Pakistani, 2 Bangladeshi and 1 Black African. Each young person was interviewed twice, at recruitment and a year later, to observe any changes in their social networks during transition. Interviews were undertaken with a semi-structured interview schedule and with the pictorial approach of Talking Mats. Both the networks the young people live within, and their sense of what the future might hold for them, are described and linked to Bronfenbrenner's ecological model of human development. The importance of the family and school is emphasised, as is the absence of engagement in leisure activities and work. Transition planning needs to start with mapping the systems individuals live within, areas of strength should be supported and parts of the system, which are not fit for purpose for these young people, should be prioritised for interventions.

The purpose of the study was to identify factors associated with the HIV transmission rate in 18 to 24 month-old children enrolled in the PMTCT programme at two selected City of Tshwane clinics. Mother-to-child transmission of HIV during labour and breastfeeding accounts for 40% of all HIV infection in children. The prevention of mother-to-child transmission of HIV programme is one effective strategy to reduce the rate of HIV infection in children. The HIV transmission rate was low at six weeks of age but increases at 18 to 24 months of age due to several factors. The researcher selected a descriptive retrospective correlational research design. A structured questionnaire was used to collect data from 60 mothers of children aged 18 to 24 months on the PMTCT programme and a data-collection form to collect data from 152 clinic records of children of the same age on the programme. The study found that the PMTCT guidelines were not properly adhered to by the nurses and the respondents. Prophylactic treatment was not provided as required and mixed feeding was prominent. The uptake of HIV test at 18 to 24 months was low compared to at 6 weeks. The transmission rate was high at 18 to 24 months compared to at 6 weeks. No factors were associated with the transmission rate / Health Studies / M.A. (Public Health)

Non-response is an error common to most surveys. In this dissertation, the error of non-response is described in terms of its sources and its contribution to the Mean Square Error of survey estimates. Various response and completion rates are defined. Techniques are examined that can be used to identify the extent of nonresponse bias in surveys. Methods to identify auxiliary variables for use in nonresponse adjustment procedures are described. Strategies for dealing with nonresponse are classified into two types, namely preventive strategies and post hoc adjustments of data. Preventive strategies discussed include the use of call-backs and follow-ups and the selection of a probability sub-sample of non-respondents for intensive follow-ups. Post hoc adjustments discussed include population and sample weighting adjustments and raking ratio estimation to compensate for unit non-response as well as various imputation methods to compensate for item non-response. / Mathematical Sciences / M.

This thesis is the study of televangelism contextualized within the country of Romania. It seeks to answer six main questions: I} When the Lord Jesus gave Christendom the global, Gospel mandate, he forced his disciples into a two thousand year struggle with, not only the message, but how to spread this message. Is the Gospel message so powerful that it will penetrate through any method of delivery? Can a former communist country be evangelized through television? 2) The next question asked in this thesis: is the message in and of itself, when conveyed through this media, sufficient to accomplish its goals? Does the media encourage the recipient to fulfill the desires of the message? What about Mass Communication Theory which espouses that television is more likely to reinforce then transform a viewer's belief? 3) The third question wrestled with: would the former communistic country of Romania, when turning to the ideals of the West, receive the Gospel message with greater or lesser significance through the media of television, or would other forms of communication be more desirable? Would television, in comparison to Crusade or Film Evangelism, be a more ideal media for the Gospel at this juncture in Romania's history? 4) Television allows large audiences to be reached with staggering efficiency, but does the medium itself impose limits on the kind of evangelism that can be done? What type of church grows out of an electronic medium? Would television gather a church "unto itself?" 5) In fulfilling the great commission, many organizations and mission groups have arisen with the desire to carry the Gospel message to the ends of the earth with whatever means available, including CBN, who uses television. Can television reach the masses, including the poor, in Eastern block countries? 6) The final question addressed in this research: what are the long term effects of televangelism in this former communistic country? Would a one time television program, given in one week, yield results that can be determined two years later? These questions were not only wrestled with, but conclusions were drawn to make evangelism and particularly televangelism more efficacious. / Philosophy, Practical & Systematic Theology / Th. D.

The aim of the study was to explore what methods the personnel in five residential care homes in Götaland, Sweden, implement to integrate unaccompanied minors. The study investigated how and what methods are constructed as well as how the social interaction between the unaccompanied minors and the personnel at the homes bring about the learning of the methods. Five face-to-face semi-structured interviews were conducted and analysed through the perspective of social construction and social learning theory. The result revealed that the methods are not clearly identified by the personnel. The personals are still learning how to work with unaccompanied minors from their experiences. This indicates that the practice is at its infant stage. The study found a wide variety of methods, which were based on the child and where some methods intend to build good relationship, to integrate the children into society and to facilitate the development of strategies and methods. The study also addresses the issue of how the methods and strategies can be affected by the dynamic migratory flow and the question of evidence based practice within this field.
