Energy-Efficient Computation Offloading for UAV-Assisted MEC: A Two-Stage Optimization Scheme

In addition to the stationary mobile edge computing (MEC) servers, a few MEC surrogates that possess a certain mobility and computation capacity, e.g., flying unmanned aerial vehicles (UAVs) and private vehicles, have risen as powerful counterparts for service provision. In this article, we design a two-stage online scheduling scheme, targeting computation offloading in a UAV-assisted MEC system. On our stage-one formulation, an online scheduling framework is proposed for dynamic adjustment of mobile users' CPU frequency and their transmission power, aiming at producing a socially beneficial solution to users. But the major impediment during our investigation lies in that users might not unconditionally follow the scheduling decision released by servers as a result of their individual rationality. In this regard, we formulate each step of online scheduling on stage one into a non-cooperative game with potential competition over the limited radio resource. As a solution, a centralized online scheduling algorithm, called ONCCO, is proposed, which significantly promotes social benefit on the basis of the users' individual rationality. On our stage-two formulation, we are working towards the optimization of UAV computation resource provision, aiming at minimizing the energy consumption of UAVs during such a process, and correspondingly, another algorithm, called WS-UAV, is given as a solution. Finally, extensive experiments via numerical simulation are conducted for an evaluation purpose, by which we show that our proposed algorithms achieve satisfying performance enhancement in terms of energy conservation and sustainable service provision.

Service User and Service Provider Perceptions of Enablers and Barriers for Refugee and Asylum-Seeking Women Accessing and Engaging with Perinatal Mental Health Care Services in the WHO European Region: A Scoping Review Protocol

There is a need to understand the specific perinatal mental health care needs of migrant subgroups who often have differing health care needs and specific barriers to accessing and engaging with health care services. It is important to have evidence about the WHO European context given the rising numbers of refugees and asylum seekers in the region. The aim of this scoping review is to map the factors that enable and prevent access and engagement of refugee and asylum-seeking women with perinatal mental health care services in the WHO European Region, from the perspectives of service providers and service users. The database search will include PsycINFO, Cochrane, Web of Science, MEDLINE, EMBASE, CINAHL complete, Scopus, Academic Search Complete, and Maternity and Infant Care (OVID). Search results will be exported to an online tool that provides a platform to help manage the review process, including title, abstract, and full-text screening and voting by reviewers independently. Data concerning access and engagement with health care services will be mapped on to the candidacy framework. Systematically searching evidence within the WHO European region and examining this evidence through the candidacy lens will help develop a more comprehensive and a deeper conceptual understanding of the barriers and levers of access and engagement with perinatal mental health care services, whilst identifying gaps in existing evidence. Exploring factors that influence access and engagement for refugee and asylum-seeking women from the perspective of key stakeholders in the service provision and/or service utilisation of perinatal mental health care services will add a more comprehensive understanding of the recursive relationship between service provision and use.

The Experiences and Views of Service Providers on the Mental Health and Well-Being Services for Syrian Refugees in Coventry and Warwickshire

Objectives: Previous literature demonstrated that, even when mental health and psychological support services are available for refugees, there may still be obstacles in accessing services. This is the first known study to explore the experiences of mental-health and well-being services for Syrian refugees in Coventry and Warwickshire, United Kingdom. The research investigates the views and perceptions of service providers on the current mental-health and well-being services provided for this population. Methods: Eight service providers participated in semistructured interviews and focus groups, and the data were analyzed using thematic analysis. Results: Three main themes emerged from an analysis of the data: “positive aspects of service delivery,” “service challenges,” and “recommendations for service improvements and quality.” Conclusion: The findings bring to the fore specific gaps in current provision and interpreting services. Recommendations for proposed improvements in service provision and policy as well as clinical implications are included in this article.

Tiebout Sorting, Zoning, and Property Tax Rates

This paper examines certain implications from the literature on Tiebout’s model of local gov-ernment service provision, particularly Hamilton’s extension of the model to include local control of land use and property taxation. Our empirical analysis focuses on the use of fiscal zoning to lower property tax rates, a topic that has not been addressed in the extensive Tiebout literature. Using data for over 100 municipalities in the Miami, Florida, metropolitan area, we specify property tax rates as a function of fiscal zoning measures, other municipal characteristics, and tax mimicking. We conclude that single-family zoning is by far the most important variable ex-plaining municipal property tax rates.

Preference of Older Adults for Flexibility in Service and Providers in Community-Based Social Care: A Discrete Choice Experiment

Empowerment of control and choice of the service users in health and social care has been incorporated into service provision in various countries. This study aimed to elicit the preference of community-based long-term care (LTC) service users on levels of flexibility in service provision. A discrete choice experiment was performed among older community care service users to measure their preference for attributes of LTC services identified from a prior qualitative study. Each participant was asked to make choices in six choice tasks with two alternatives of hypothetical LTC services that were generated from the attributes. A generalized multinomial logistic model was applied to determine the relative importance and willingness to pay for the attributes. It found that the participants preferred multiple flexible providers, determining services by themselves, meeting case managers every month and social workers as sources of information on service provision. Significant preference heterogeneity was found for flexibility in providers and flexibility in services between those with and without activity of daily living impairment. The findings highlighted the preference of older adults for greater flexibility in LTC, while they rely heavily on social workers in decision making. The enhancement of flexibility in LTC should be supported by policies that allow the older service users to make decisions based on their own preferences or communication with social workers instead of determining the services and providers for them. Options should be offered to users to decide their preferred level of flexibility to better reflect their divided preferences.

Making doctors stay: Rethinking doctor retention policy in a contracted-out primary healthcare setting in urban Bangladesh

Background “Contracting Out” is a popular strategy to expand coverage and utilization of health services. Bangladesh began contracting out primary healthcare services to NGOs in urban areas through the Urban Primary Health Care Project (UPHCP) in 1998. Over the three phases of this project, retention of trained and skilled human resources, especially doctors, proved to be an intractable challenge. This paper highlights the issues influencing doctor’s retention both in managerial as well as service provision level in the contracted-out setting. Methodology In this qualitative study, 42 Key Informant Interviews were undertaken with individuals involved with UPHCP in various levels including relevant ministries, project personnel representing the City Corporations and municipalities, NGO managers and doctors. Verbatim transcripts were coded in ATLAS.ti and analyzed using the thematic analysis. Document review was done for data triangulation. Results The most cited problem was a low salary structure in contrast to public sector pay scale followed by a dearth of other financial incentives such as performance-based incentives, provident funds and gratuities. Lack of career ladder, for those in both managerial and service delivery roles, was also identified as a factor hindering staff retention. Other disincentives included inadequate opportunities for training to improve clinical skills, ineffective staffing arrangements, security issues during night shifts, abuse from community members in the context of critical patient management, and lack of job security after project completion. Conclusions An adequate, efficient and dedicated health workforce is a pre-requisite for quality service provision and patient utilization of these services. Improved career development opportunities, the provision of salaries and incentives, and a safer working environment are necessary actions to retain and motivate those serving in managerial and service delivery positions in contracting out arrangements.

Collaborative public service provision archetypes in healthcare emergencies: a case of COVID-19 administration in Sri Lanka

PurposeThis paper examines how the properties and patterns of a collaborative “networked hierarchy” incident command system (ICS) archetype can provide incident command centres with extra capabilities to manage public service delivery during COVID-19.Design/methodology/approachThe paper illustrates the case of Sri Lanka's COVID-19 administration during its “first wave” (from 15 February to 1 September 2020). Primary data were collected through in-depth interviews with government officials who were directly involved in the administration of the COVID-19 outbreak. Secondary data sources were government publications and web sources. The data were analysed and interpreted by using narrative analysis and archetype theory respectively.FindingsThe findings highlight how Sri Lanka's public sector responses to COVID-19 have followed a collaborative “networked hierarchy” ICS archetype. More specifically, the government changed its normative ICS “properties” by incorporating a diverse group of intergovernmental agencies such as the police, the military, the health service and administrative services by articulating new patterns of collaborative working, namely, organisational values, beliefs and ideas that fit with the Sri Lankan public service context.Originality/valueIn responding to high magnitude healthcare emergencies, the flexibility of a collaborative networked ICS hierarchy enables different balances of organisational properties to be incorporated, such as hierarchy and horizontal networking and “patterns” in public service provision.

GROSS MARGIN AS A CATEGORY FOR EVALUATING THE EFFICIENCY OF PUBLIC SERVICE PROVISION

Contemporary management concepts in public organisations emphasize the adaptation and implementation of selected management methods tested in commercial sector organisations. They are used to improve the processes of providing public services and to ensure savings, especially in terms of the level of costs. One such instrument is variable cost accounting, which, through the gross margin value, allows to assess both the ability of an organisation to provide specific services and to ensure the widest possible range of services, as well as to identify those who are responsible for the functioning of selected responsibility centres. The study attempts to present an algorithm of conduct ensuring the effective use of variable cost accounting in the process of improving the operation of public organisations.

COVID and Counseling

Due to the COVID-19 crisis, the mental health profession has shifted to online service provision, or telehealth. The aim of this chapter is to describe the COVID-19 crisis and subsequent changes that occurred to mental health service provision; the benefits and drawbacks to telehealth from practical, ethical, and cultural perspectives; and the learning opportunities that have come from this crisis. Finally, reflections on the future of the counseling profession and trends in service provision for serving an increasingly diverse population will be analyzed.
