This paper's aim it to analyze added value that the theses e‐submission system (tool) gave to the NTUA IR service.

The paper describes the e‐submission tool, its procedures and evaluates its use.

The tool improved the IR service, which can be certified by the continuing evaluation process. This process produced the following main results: the automated batch importing feature should be integrated into the e‐submission system; IR service tutorials should be given to the secretariats, faculty and students; and in‐house service marketing should be conducted.

The present study provides a starting‐point for further research in DL open source software.

The paper shows that the tool helped NTUA users in submitting their e‐theses, and the IR staff in organizing efficiently the service workflow and the data integration into the DSpace system. The process weaknesses rectifications will enhanse the service and allow its broadness to all NTUA departments. This tool implementation may start a debate to the DSpace community in using proxies between DSpace platform and the end user, as an alternative.

Predicting a patient's length of stay (LOS) in a hospital setting has been widely researched. Accurately predicting an individual's LOS can have a significant impact on a healthcare provider's ability to care for individuals by allowing them to properly prepare and manage resources. A hospital's productivity requires a delicate balance of maintaining enough staffing and resources without being overly equipped or wasteful. This has become even more important in light of the current COVID-19 pandemic, during which emergency departments around the globe have been inundated with patients and are struggling to manage their resources.

In this study, the authors focus on the prediction of LOS at the time of admission in emergency departments at Rhode Island hospitals through discharge data obtained from the Rhode Island Department of Health over the time period of 2012 and 2013. This work also explores the distribution of discharge dispositions in an effort to better characterize the resources patients require upon leaving the emergency department.

Despite numerous studies on the separate health consequences of economic crises and post-migration difficulties, very little is known about the processes through which the intersection of economic crisis and post-migration adversity contribute to migrants’ health vulnerabilities. The purpose of this paper is to examine existing literature about how newly arrived and long-term migrants’ health and well-being are affected by the economic crisis in Greece.

The ongoing economic recession in Greece, combined with the recent migration crisis, provided an adequate context for investigating migrants’ health and well-being. A narrative literature review was performed on whether and how migrants’ health and well-being are affected by the economic and the migration crises in the particular case of Greece. Papers published between January 2010 and December 2017 were selected based on review of titles and abstracts, followed by a full text review.

The review identified a surprisingly limited number of relevant studies. Ultimately five studies were selected and their findings summarised. There was only one study attempting to unravel the specific processes through which the crisis and the post-migration problems impact cumulatively on migrants’ health and well-being and to suggest healthcare improvements. Further research on this topic is urgently needed.

This paper explores existing research looking at how migrants’ health and well-being are affected by the economic and the migration crises in Greece. The emerging dearth of research evidence on the above topic is also critically discussed from a socio-political point of view and recommendations are made related to healthcare practice and services set up for migrants’ health and care.

This paper aims to explore the challenges and opportunities of blockchain technology adoption from the lens of the technological–organisational–environmental (TOE) framework for operational excellence in the UK automotive industry context.

The research methodology of this study follows a systematic review approach, which analyses existing academic published research papers in the top 35 academic journals. There was no specific timeframe established for this study and shortlisting the articles through a set of used keywords. A sample of 71 articles was shortlisted and analysed to provide a discussion on technological and management challenges and opportunities of blockchain adoption from the lens of the TOE framework for operational excellence.

The findings of this study present significant theoretical and managerial implications and deep understanding for firms seeking to understand the challenges and opportunities of blockchain adoption for their operational excellence.

The systematic literature approach was considered for the present study to explore existing academic papers on technological and management challenges and opportunities from the lens of TOE framework for operational excellence, whereas a more specified method meta-analysis can be considered for future research. The study has been explored in the UK automotive industry context, which has been considered as the limitation of generalisation across countries and industries.

This paper represents the most comprehensive literature study related to the technological and management challenges and opportunities of blockchain from the TOE framework angle for operational excellence.

This paper aims to contribute to understanding the crucial influence of risks on the capital structure of project financing (PF) initiatives in the energy sector.

The debt leverage of a capital investment is selected as the response variable, and its relation with select identified risk factors is examined using a regression analysis on a data set of 72 projects carried out all over the world in the energy industry.

Results have highlighted that the debt leverage is significantly influenced by several sources of risk measured through specific indicators, namely, country stability index, the construction duration, the concession period and the average size of partners. Therefore, country, project and special purpose vehicle-related risks have been shown to have an impact on the debt leverage of a PF scheme.

The results could support both investors and lenders to better define the financial leverage of projects delivered under a PF mechanism. In particular, the study could help to have a better understanding of the main factors that influence the debt leverage in PF initiatives.

This paper contributes to filling the lack of works addressing the relationship between risk factors and capital structure in PF projects. In this way, this research leads to a better understanding of the risk factors that influence the capital structure of a PF initiative, and they have, therefore, been proposed as a basis for the establishment of improved methods to design refined capital structures.

This study aims to provide a systematic review about the Internet of Things (IoT) and its impacts on happiness. It intends to serve as a platform for further research as it is sparse in in-depth analysis.

This systematic review initially observed 2,501 literary articles through the ScienceDirect and WorldCat search engines before narrowing it down to 72 articles based on subject matter relevance in the abstract and keywords. Accounting for duplicates between search engines, the count was reduced to 66 articles. To finally narrow down all the literature used in this systematic review, 66 articles were given a critical readthrough. The count was finally reduced to 53 total articles used in this systematic review.

This paper necessitates the claim that IoT will likely impact many aspects of our everyday lives. Through the literature observed, it was found that IoT will have some significant and positive impacts on people's welfare and lives. The unprecedented nature of IoTs impacts on society should warrant further research moving forward.

While the literature presented in this systematic review shows that IoT can positively impact the perceived or explicit happiness of people, the amount of literature found to supplement this argument is still on the lower end. They also necessitate the need for both greater depth and variety in this field of research.

Since technology is already a pervasive element of most people’s contemporary lives, it stands to reason that the most important factors to consider will be in how we might benefit from IoT or, more notably, how IoT can enhance our levels of happiness. A significant implication is its ability to reduce the gap in happiness levels between urban and rural areas.

Currently, the literature directly tackling the quantification of IoTs perceived influence on happiness has yet to be truly discussed broadly. This systematic review serves as a starting point for further discussion in the subject matter. In addition, this paper may lead to a better understanding of the IoT technology and how we can best advance and adapt it to the benefits of the society.

This review aims to examine the literature on refugees’ and asylum seekers’ resilience, its historical evolution, key principles, assumptions and recommendations, while focusing on the Canadian context.

A narrative literature review has been applied to this manuscript. This approach allows the integration of a wide scope of literature and perspectives, from academic literature to grey literature (e.g. governmental reports and dissertations). Nevertheless, the limitations of this type of review were also discussed.

In spite of the gaining popularity of the resilience lens, which emphasizes an individual’s ability to overcome adversities and stressful events, more work is required for its effective integration into health practice, programs and policies, particularly as it relates to refugees’ and asylum seekers’ mental health care.

Careful consideration of refugees’ and asylum seekers’ mental health needs and Canadian mental health service delivery and policies is a critical first step in reaching such a goal.
