    A Design Science Research Approach to Smart and Collaborative Urban Supply Networks

    Get PDF
    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    Perceptions of surveillance: exploring feelings held by Black community leaders in Boston toward camera enforcement of roadway infractions

    Roadway camera enforcement programs have been found to effectively reduce vehicle travel speeds, as well as decrease the number and severity of collisions. Despite a wealth of evaluative research confirming this enforcement approach's aptitude at promoting safer roadway behavior, fewer than 50 % of US states currently host camera-based programs. Public opposition is frequently cited as the cause for the slow proliferation of this enforcement strategy. However, with public demand for police reform having an increasing presence on the national political stage, how might feelings toward camera technology currently stand among groups most marginalized by existing enforcement systems, and how might those feelings vary by type of enforcement application? Through a series of focus groups, this work centers Black voices on matters of surveillance and roadway enforcement by discussing sentiment toward camera programs with Black community leaders. This discussion is contextually situated in Boston, Massachusetts, where legislation that would allow for camera enforcement of roadway infractions is actively being deliberated in the State Senate. Findings culminate in a list of right-sizing and procedural recommendations for policy makers hoping to gain support for camera enforcement, improve roadway safety, and advance racial equity in our systems of policing and governance

    Constructing a Theological Framework That Revitalizes the Missional Nature of Churches of Christ in South Australia

    This thesis addresses the need for a theological framework that revitalizes the missional nature of Churches of Christ in South Australia. The problem identified within this ministry context was a lack of clear theological principles that informed a common understanding of identity for missional engagement. The purpose of the project was to create a study guide that informs common theological commitments and grounds congregations for missional vitality. A research and development team made up of seven Church of Christ ministers from different backgrounds was assembled to design a curriculum that addressed the problem. Through eight two-hour sessions over four months in the first half of 2022, the team discussed a theological framework that could revitalize mission. This was informed by a Trinitarian theological rationale introduced as perichoresis. The conceptual framework for discussions included (1) the historical and theological foundations of Churches of Christ, (2) a Trinitarian doctrine of God presented as perichoresis, (3) contemporary congregational practices, and (4) a theological proposal for re-imagining mission. The team developed a study guide that promotes a dynamic theological framework for practicing theology and revitalizing the missional nature of the church. The artifact, Movement & Identity: Participating in the Life of God’s Mission, was evaluated by the team and members of Church of Christ congregations in South Australia. The curriculum is designed to assist participants with practical theological interpretation through (1) discovering new ideas about God in the context of Churches of Christ traditions, (2) engaging with contextual theology in community, (3) participating in God’s mission, and (4) reflecting on how God’s agency transforms the church. The development of the study guide will stimulate a practical theological framework that promotes dynamic theological dialogue and missional vitality for Churches of Christ in South Australia

    Exploring the Training Factors that Influence the Role of Teaching Assistants to Teach to Students With SEND in a Mainstream Classroom in England

    With the implementation of inclusive education having become increasingly valued over the years, the training of Teaching Assistants (TAs) is now more important than ever, given that they work alongside pupils with special educational needs and disabilities (hereinafter SEND) in mainstream education classrooms. The current study explored the training factors that influence the role of TAs when it comes to teaching SEND students in mainstream classrooms in England during their one-year training period. This work aimed to increase understanding of how the training of TAs is seen to influence the development of their personal knowledge and professional skills. The study has significance for our comprehension of the connection between the TAs’ training and the quality of education in the classroom. In addition, this work investigated whether there existed a correlation between the teaching experience of TAs and their background information, such as their gender, age, grade level taught, years of teaching experience, and qualification level. A critical realist theoretical approach was adopted for this two-phased study, which involved the mixing of adaptive and grounded theories respectively. The multi-method project featured 13 case studies, each of which involved a trainee TA, his/her college tutor, and the classroom teacher who was supervising the trainee TA. The analysis was based on using semi-structured interviews, various questionnaires, and non-participant observation methods for each of these case studies during the TA’s one-year training period. The primary analysis of the research was completed by comparing the various kinds of data collected from the participants in the first and second data collection stages of each case. Further analysis involved cross-case analysis using a grounded theory approach, which made it possible to draw conclusions and put forth several core propositions. Compared with previous research, the findings of the current study reveal many implications for the training and deployment conditions of TAs, while they also challenge the prevailing approaches in many aspects, in addition to offering more diversified, enriched, and comprehensive explanations of the critical pedagogical issues

    Long-acting reversible contraception (LARC) after pregnancy and childbirth

    Get PDF
    Background and aims: Unmet need of contraception is a global challenge. The need of additional visits to initiate contraception is found to be a barrier for postpartum and postabortion contraceptive care. The IUDs and the implant are called long-acting reversible contraception (LARC). The LARC-method can be used for years without having to remember a contraceptive during sexual intercourse or, in case of hormonal contraception, every day, week or month. The overall aim of this thesis was to add knowledge to the field of long-acting reversible contraception after pregnancy in Sweden in our effort to improve the quality of contraceptive care after pregnancy and childbirth. Methods and main results: Study 1 was a retrospective cohort study including 11,066 women. Data was extracted from medical records regarding attendance to the postpartum visit and choice of contraception, breastfeeding, and abortion during 12-24 months after delivery. The primary outcome was the proportion of induced abortions during follow-up, with the outcome measure of abortion being a surrogate for unintended pregnancy. Among attendees to the follow up 2.1 % had an abortion compared to 3.6 % among nonattendants. A decision to use LARC was associated with a lower risk of abortion (OR 0.74; 95% CI 0.60-0.91; p = .005), as was exclusive breastfeeding (p < .001). Smoking and having had an earlier abortion were associated with a higher risk of abortion during the follow-up. Study II and III were open-label, prospective, randomised, controlled, multicenter studies. In study II, 101 women were either allocated to early placement (52/101) of a hormonal IUD within 48 hours after vaginal delivery or to standard placement (49/101) at 6-8 weeks postpartum. Follow-up was one year after IUD placement. Inclusion was prematurely stopped after an interim analysis due to high expulsion rate in the early placement group, and instead of 600 women only 101 were included. In the early placement group 23/52 (44.2 %) of devices were expelled within a year and 10 women had the hormonal device replaced. In the standard placement group there were no expulsions. The IUD continuation rate for the early group was 37/52 (71.2%), compared to 41/49 (83.7%, p = .13) for the standard placement group at study closure. In study III, 240 women seeking medical abortion up to 63 days´ gestation were randomised to either IUD placement within 48 hours (120/240) after completed abortion or to IUD placement at 2-4 weeks (120/240) after abortion. Follow-up was one year after abortion. The primary outcome was IUD use at 6 months postabortion. In the early placement group (intervention), 91/111 (82%) women used IUD at 6 months compared to 87/112 (77.7%) in the later placement (control) group (p= .51) Pain scores at IUD placement (measured by the visual analogue scale) were lower in the intervention group (p= .002). Women in the intervention group preferred the allocated time significantly more often compared to the control group (p= .03). There was no difference regarding expulsion. In study II and III there were no differences regarding safety profile between groups. Study IV was a qualitative study where 20 women who had undergone elective caesarean section (CS) were interviewed within 6 weeks of CS, to enable deeper understanding of women´s preferences and needs regarding contraceptive services at the time of pregnancy. Ten of the interviewees had chosen IUD placement during the latest CS. Three themes were identified; Receptivity to contraceptive counseling during pregnancy; Communication and decision-making of postpartum contraception during pregnancy and Needs to navigate in the Maternal Health Care System to receive contraceptive services before and after caesarean section. Women were generally positive to contraceptive counseling from about 25 gestational weeks and expressed positive attitudes about the concept of antenatal counseling. Feeling involved and informed was important, but few women had been involved in antenatal counseling. Women who had chosen IUD placement during CS were usually satisfied with the decision. Some interviewees expressed a need to navigate in the contraceptive services by themselves. The communication and coordinating units that should integrate around the woman have not sufficiently adapted to new evidence, needs and conditions. Conclusions: The choice of LARC postpartum is associated with lower risk for unintended pregnancy compared to the choice of other contraceptives or no choice at all. Attendance to the postpartum visit is a prerequisite to initiate LARC when provision of early/immediate LARC initiation postpartum is not part of the established contraceptive health care. Placement of a hormonal IUD within 48 hours after vaginal delivery seems safe, accepted by patients but associated with much higher expulsion rates compared to placement 6- 12 weeks postpartum. Early placement of an IUD within 48 hours after completed medical abortion does not lead to higher continuation rates at one year after abortion compared to standard placement 2-4 weeks after abortion when devices are provided free of charge. Early placement seems safe, preferred by patients, and associated with lower pain scores compared to standard IUD placement postabortion. Antenatal counseling for contraceptive method to use postpartum seems acceptable to women from around 25 gestational weeks. To have the opportunity to discuss contraception antenatally and enable placement during planned CS is generally considered valuable

    ‘If I am on ART, my new-born baby should be put on treatment immediately’: Exploring the acceptability, and appropriateness of Cepheid Xpert HIV-1 Qual assay for early infant diagnosis of HIV in Malawi

    Early infant diagnosis of HIV (EID-HIV) is key to reducing paediatric HIV mortality. Traditional approaches for diagnosing HIV in exposed infants are usually unable to optimally contribute to EID. Point-of-care testing such as Cepheid Xpert HIV-1 Qual assay-1 (XPertHIV) are available and could improve EID-HIV in resource constrained and high HIV burden contexts. We investigated the acceptability and perceived appropriateness of XpertHIV for EID-HIV in Mulanje Hospital, Malawi. Qualitative cross-sectional study using semi-structured interviews (SSI) among caregivers and health care workers at Mulanje District Hospital. The qualitative study was nested within a larger diagnostic study that evaluated the performance of XpertHIV using whole-blood-sample in a resource limited and high burden setting. A total of 65 SSIs were conducted among caregivers (n = 60) and health care providers (n = 5). Data were coded using deductive and inductive approaches while thematic approach was used to analyse data. Point-of-care XPertHIV was perceived to be acceptable among caregivers and health care providers. Caregivers’ motivations for accepting XPertHIV HIV-testing for their infants included perceived risk of HIV emanating from child’s exposure and validation of caregiver’s own HIV sero-status. Although concerns about pain of testing and blood sample volumes taken from an infant remained amplified, overall, both caregivers and health care providers felt XpertHIV was appropriate because of its quick result turn-around-time which decreased anxiety and stress, the prospect of early treatment initiation and reduction in hospital visits and related costs. Implementation of XpertHIV has a great potential to improve EID-HIV in Malawi because of its quick turn-around-time and associated benefits including overcoming access-related barriers. Scaled implementation of this diagnostic technology require a robust community engagement strategy for managing caregivers and community myths and misconceptions towards the amount of blood sample collected from infants

    Do Catholics have an external locus of evaluation? Inauthentic experiences of Catholic guilt in the pursuit of self-forgiveness

    Get PDF
    This two-part mixed methods study investigated emotional response to transgression and selffor-giveness in Catholic individuals in concert with locus of evaluation orientation following a hypothe-sis that Catholics may be particularly unable to find self-forgiveness in the teachings of their reli-gion. Study 1 was a qualitative semi-structured interview with a sample of 20 practicing Catholic participants. Questions focused on the emotive experiences of selfforgiveness and transgressions and the contribution that Catholic practices (prayer and reconciliation) make to the process. Data were analysed using thematic analysis which supported evidence of Catholic guilt but suggested that there may be some inauthenticity and insincerity with which penitents' approach reconciliato-ry practices. Study 2 used a sample of 239 Christian participants in groups of Catholics and Christian non-Catholics. Participants responded to two psychometric questionnaires: the Heartland Forgiveness Scale, and the Locus of Evaluation Inventory. Followed by two additional questions pertaining to self-forgiveness experiences, and one question requiring participants to prioritise types of forgiveness. The results found no difference between Catholics and non-Catholics in their response to self-forgiveness or locus of evaluation orientation. However, in non-Catholic Christians but not in Catholics, the frequency of religious practice correlated with higher total forgiveness and its subscales (including self-forgiveness), with more internal locus of evaluation, and with lower self-regard, suggesting that church attendance does not relate to the propensity for self-forgiveness in Catholic individuals

    Victims' Access to Justice in Trinidad and Tobago: An exploratory study of experiences and challenges of accessing criminal justice in a post-colonial society

    Get PDF
    This thesis investigates victims' access to justice in Trinidad and Tobago, using their own narratives. It seeks to capture how their experiences affected their identities as victims and citizens, alongside their perceptions of legitimacy regarding the criminal justice system. While there have been some reforms in the administration of criminal justice in Trinidad and Tobago, such reforms have not focused on victims' accessibility to the justice system. Using grounded theory methodology, qualitative data was collected through 31 in-depth interviews with victims and victim advocates. The analysis found that victims experienced interpersonal, structural, and systemic barriers at varying levels throughout the criminal justice system, which manifested as institutionalized secondary victimization, silencing and inequality. This thesis argues that such experiences not only served to appropriate conflict but demonstrates that access is often given in a very narrow sense. Furthermore, it shows a failure to encompass access to justice as appropriated conflicts are left to stagnate in the system as there is often very little resolution. Adopting a postcolonial lens to analyse victims' experiences, the analysis identified othering practices that served to institutionalize the vulnerability and powerlessness associated with victim identities. Here, it is argued that these othering practices also affected the rights consciousness of victims, delegitimating their identities as citizens. Moreover, as a result of their experiences, victims had mixed perceptions of the justice system. It is argued that while the system is a legitimate authority victims' endorsement of the system is questionable, therefore victims' experiences suggest that there is a reinforcement of the system's legal hegemony. The findings suggest that within the legal system of Trinidad and Tobago, legacies of colonialism shape the postcolonial present as the psychology and inequalities of the past are present in the interactions and processes of justice. These findings are relevant for policymakers in Trinidad and Tobago and other regions. From this study it is recognized that, to improve access to justice for victims, there needs to be a move towards victim empowerment that promotes resilience and enhances social capital. Going forward it is noted that there is a need for further research

    Implementing Health Impact Assessment as a Required Component of Government Policymaking: A Multi-Level Exploration of the Determinants of Healthy Public Policy

    Get PDF
    It is widely understood that the public policies of ‘non-health’ government sectors have greater impacts on population health than those of the traditional healthcare realm. Health Impact Assessment (HIA) is a decision support tool that identifies and promotes the health benefits of policies while also mitigating their unintended negative consequences. Despite numerous calls to do so, the Ontario government has yet to implement HIA as a required component of policy development. This dissertation therefore sought to identify the contexts and factors that may both enable and impede HIA use at the sub-national (i.e., provincial, territorial, or state) government level. The three integrated articles of this dissertation provide insights into specific aspects of the policy process as they relate to HIA. Chapter one details a case study of purposive information-seeking among public servants within Ontario’s Ministry of Education (MOE). Situated within Ontario’s Ministry of Health (MOH), chapter two presents a case study of policy collaboration between health and ‘non-health’ ministries. Finally, chapter three details a framework analysis of the political factors supporting health impact tool use in two sub-national jurisdictions – namely, Québec and South Australia. MOE respondents (N=9) identified four components of policymaking ‘due diligence’, including evidence retrieval, consultation and collaboration, referencing, and risk analysis. As prospective HIA users, they also confirmed that information is not routinely sought to mitigate the potential negative health impacts of education-based policies. MOH respondents (N=8) identified the bureaucratic hierarchy as the brokering mechanism for inter-ministerial policy development. As prospective HIA stewards, they also confirmed that the ministry does not proactively flag the potential negative health impacts of non-health sector policies. Finally, ‘lessons learned’ from case articles specific to Québec (n=12) and South Australia (n=17) identified the political factors supporting tool use at different stages of the policy cycle, including agenda setting (‘policy elites’ and ‘political culture’), implementation (‘jurisdiction’), and sustained implementation (‘institutional power’). This work provides important insights into ‘real life’ policymaking. By highlighting existing facilitators of and barriers to HIA use, the findings offer a useful starting point from which proponents may tailor context-specific strategies to sustainably implement HIA at the sub-national government level
