In order to control the COVID-19 pandemic, the governments of the world started to implement measures regarding social distance and social contacts, including closures of cities, work and study relocations, and work suspension. The epidemical situation and the lockdown of the economy by governments in various countries caused changes in production, changes in the habits of energy consumers and other energy-related changes. This article analyses the impact of the global pandemic on the energy sector and the relationship with the progress to the sustainability of the energy sector. The systematic literature review was performed in the Web of Science (WoS) database. The research follows recommendations of the SALSA (Search, Appraisal, Synthesis and Analysis) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) approaches. A total of 113 relevant articles were selected for the analysis. All selected articles were categorized according to their application and impact areas. The five main impact areas of the COVID-19 pandemic to the sustainability of the energy sector were identified: consumption and energy demand; air pollution; investments in renewable energy; energy poverty; and energy system flexibility. Based on the current research findings and perception of the problem, the main insights for future research in the field are provided.

Abstract The building energy sector is not immune from the physical impacts of climate change and must adapt. The impacts are more gradual, such as changes to heating and cooling demand. Disruptions to the energy system can also have significant knock-on effects on other critical services. To improve the climate resilience of the building energy system, governments need to design and implement frameworks that encourage prudent adaptation, while the private sector should assess the risks and impacts as part of its investment decisions. Comprehensive studies covering the impact of climate change on the building energy sector are still lacking, though some regional and sector-specific analysis exists. The buildings sector has been examined in more depth than most, with studies finding that temperature increases are expected to boost demand for air conditioning, while fuel consumption for space heating will be reduced. For the follow-up research activity the question has been posed: How can the climate changing trends and the building sector rising energy demand meet in urban environment? As an outlook this present paper can be defined as an ex-ante document in the DENZERO Project towards generating the Hungarian Climate Severity/Energy Index.

ABSTRACT Introduction Soldiers are expected to deploy worldwide and must be medically ready in order to accomplish their mission. Soldiers unable to deploy for an extended period of time because of chronic pain or other conditions undergo an evaluation for medical retirement. A retrospective analysis of existing longitudinal data from an Interdisciplinary Pain Management Center (IPMC) was used to evaluate the temporal relationship between the time of initial duty restriction and referral for comprehensive pain care to being evaluated for medical retirement. Methods Patients were adults (>18 years old) and were cared for in an IPMC at least once between May 1, 2014 and February 28, 2018. A total of 1,764 patients were included in the final analysis. Logistic regression was used to evaluate the impact of duration between date of first duty restriction documentation and IPMC referral to the outcome variable of establishment of a permanent 3 (P3) profile. Results The duration between date of first duty restriction and IPMC referral showed a curvilinear relationship to probability of a P3 profile. According to our model, a longer duration before referral is associated with an increased probability of a subsequent P3 profile with the highest probability peaking at 19 months. The probability of P3 declines gradually for those who were referred later. Discussion This is the first time the relationship between time of initial duty restriction, referral to an IPMC, and subsequent P3 or higher profile has been tested. Future research is needed to examine medical conditions listed on the profile to see how they might contribute to the cause of referral to the IPMC. Conclusion A longer duration between initial duty restriction and referral to IPMC was associated with higher odds of subsequent P3 status for up to 19 months. Referral to an IPMC for comprehensive pain care early in the course of chronic pain conditions may reduce the likelihood of P3 profile and eventual medical retirement of soldiers.

Electromobility is a new approach to the reduction of CO2 emissions and the deceleration of global warming. Its environmental impacts are often compared to traditional mobility solutions based on gasoline or diesel engines. The comparison pertains mostly to the single life cycle of a battery. The impact of multiple life cycles remains an important, and yet unanswered, question. The aim of this paper is to demonstrate advances of 2nd life applications for lithium ion batteries from electric vehicles based on their energy demand. Therefore, it highlights the limitations of a conventional life cycle analysis (LCA) and presents a supplementary method of analysis by providing the design and results of a meta study on the environmental impact of lithium ion batteries. The study focuses on energy demand, and investigates its total impact for different cases considering 2nd life applications such as (C1) material recycling, (C2) repurposing and (C3) reuse. Required reprocessing methods such as remanufacturing of batteries lie at the basis of these 2nd life applications. Batteries are used in their 2nd lives for stationary energy storage (C2, repurpose) and electric vehicles (C3, reuse). The study results confirm that both of these 2nd life applications require less energy than the recycling of batteries at the end of their first life and the production of new batteries. The paper concludes by identifying future research areas in order to generate precise forecasts for 2nd life applications and their industrial dissemination.

Tourism in the Gulf Cooperation Council (GCC) countries has recently been considered by policymakers as a new avenue for economic diversification. Despite the considerable literature concerning the impact of tourism worldwide, only a limited number of studies have looked at the tourism sector in the GCC region or analyzed its economic, sociocultural, and environmental impacts. This article therefore conducts a systematic review of the state of the literature related to tourism in the GCC region. It provides effective insights about the current status, gaps, and challenges and proposes future research directions in this area for academics, practitioners, and policymakers with an interest in regional tourism development. The preferred reporting items for systematic reviews and meta-analyses approach was used to identify and select the papers. Some 23 papers were identified and analyzed. The majority of these studies focused on the United Arab Emirates, specifically the Dubai emirate. We found the most dominant research theme to be tourism planning.

Organizational scholars concurred that positive workplace relationships with others can helps employee to gain from these relationships but, they lack insights into how or why this occurs. Moreover, the relationship dynamics focus on what the relationships provide without considering the how these relationships initiated, builds and maintains. To line of this, the current study aims to find the impact of mentoring functions (career, psychosocial, role modeling) and employee performance (career success, organization citizenship behavior, and job performance) via mediating effect of relational self-efficacy. For this purpose, the data were gathered from 310 branch banking employees of Pakistani conventional banks. PLS-SEM was used for data analysis. The results indicate that there is direct relationship between mentoring functions and employee’s performance. Moreover, the finding also shows that employee relational self-efficacy mediates the relationship between mentoring functions and employee performance. Theoretical and practical implications are discussed along with suggestions for future research.

Background: Impact in research encompasses health, economic, and cultural benefits beyond adding to the knowledge base. Funders are under immense pressure to be accountable for the paybacks from funded research.Aims and objectives: The aim of this study was to look into the impact of funded biomedical research between the years 2005 and 2015 in Malaysia from the aspects of knowledge production, research targeting and capacity building, as well as health system policy and decision making.Methods: This study employed a convergent parallel mixed-methods research design. Biomedical projects related to breast cancer, coronary heart disease, and dengue, funded by the Ministry of Health (MOH), Ministry of Higher Education (MOHE), and Ministry of Science, Technology, and Innovation (MOSTI) between the years 2005 and 2015, were included.Findings: From the questionnaire responses (n=58), on average each funded project managed to produce two outputs and one higher degree student. More than half (61.4%) of the funded projects led to subsequent future research. However, low citations in systematic reviews (10.3%), health policies (6.9%), and clinical practice guidelines (5.2%) were reported. In-depth interviews with the key opinion leaders also saw that most of the local research findings were found to be irrelevant to be adopted into policies by the policymakers.Discussion and conclusions: Paybacks on knowledge production as well as research targeting and capacity building had been achieved, but impact on health system policy and decision making had not been well attained, due to the lack of relevant research findings needed by the policymakers.<br />Key messages<br /><ul><li>Payback on knowledge production was achieved, as there had been a lot of new knowledge generated as captured in academic publications, conference proceedings, policy briefs, technical reports, and research highlights, which is important to advance the frontiers of knowledge.</li><br /><li>Payback on research targeting was achieved, with the current research leading to future study with identification of the knowledge gap and generation of new ideas for new research.</li><br /><li>Payback on capacity building was achieved with the training of researchers, building up research capacity and competencies, production of MSc and PhD graduates, promotion of lecturers, and development of new partnerships and networks.</li><br /><li>Impact on health system policy and decision making was not well attained.

The Relationship

Since the 1960s, Australian scientists have speculated on the impact of human arrival on fire regimes in Australia, and on the relationship of landscape fire to extinction of the Pleistocene megafauna of Australia. These speculations have produced a series of contrasting hypotheses that can now be tested using evidence collected over the past two decades. In the present paper, I summarise those hypotheses and review that evidence. The main conclusions of this are that (1) the effects of people on fire regimes in the Pleistocene were modest at the continental scale, and difficult to distinguish from climatic controls on fire, (2) the arrival of people triggered extinction of Australia’s megafauna, but fire had little or no role in the extinction of those animals, which was probably due primarily to hunting and (3) megafaunal extinction is likely to have caused a cascade of changes that included increased fire, but only in some environments. We do not yet understand what environmental factors controlled the strength and nature of cascading effects of megafaunal extinction. This is an important topic for future research.

Purpose – It is worth focusing on the examination of factors influencing the quality of the work environment. The purpose of this paper is to verify the influence of the HRM system and organisational trust on employee commitment. Design/methodology/approach – The survey was conducted in Poland among 370 employees in organisations from two sectors of the economy: services and industry. The verification of the theoretical model was performed based on structural equation modelling. Findings – Research findings made it possible to successfully verify the model of the relationship between the HRM system (practices, process), organisational trust and commitment. The starting point for trust in an organisation followed by commitment is the HRM system. It seems that the impact of the HRM process on creating organisational trust is higher. Research findings have also confirmed a relationship between each type of organisational trust and calculative commitment based on benefits, which is a strong determinant of affective commitment. Organisational trust is, therefore, an intermediary factor because the organisation must build trust in employees first before they become affectively committed. Originality/value – Current studies have not examined the issue of a mutual relationship between three constructs: perceived HRM practices and process, organisational trust and commitment. What is more, previous research was confined to the constructs analysed holistically without considering their complexity (different types of trust and commitment). In addition, the authors attempted to enrich Allen and Mayer’s (1991) model with a new aspect of the commitment – calculative, which is linked to the benefits received by employees. The authors also identified the mediating influence of the trust and calculative commitment onto the affective commitment.

This paper is an investigation into the issues around how we calculate CO2 emissions in the built environment. At present, in Building Regulations and GHG Protocol calculations used for buildings and corporate CO2 emissions calculations, it is standard to use a single number for the CO2 emission factor of each source. This paper considers how energy demand, particularly electricity at different times of the day, season and even year can differ in terms of its CO2 emissions. This paper models three different building types (retail, office and home) using standard software to estimate a profile of energy demand. It then considers how CO2 emissions calculations differ between using the single standard emissions factor and using an hourly emissions factor based on real electrical grid generation over a year. The paper also examines the impact of considering lifetime emissions factors rather than one-year factors using UK government projections. The results show that there is a significant difference to the analysis of benefit in terms of CO2 emissions from different measures – both intra- and inter-year – due to the varying CO2 emissions intensity, even when they deliver the same amount of net energy saving. Other factors not considered in this paper, such as impact on peak generation and air quality, are likely to be important when considering whole-system impacts. In line with this, it is recommended that moves are made to incorporate intra- and inter-year emissions factor changes in methodologies for calculating CO2 emissions. (This is particularly important as demand side response and energy storage, although generally accepted as important in the decarbonisation of the energy system at present will show as an increase in CO2 emissions when using a single number.) Further work quantifying the impact on air quality and peak generation capacity should also be considered. Practical application: This paper aims to help practitioners to understand the performance gap between how systems need to be designed in order to meet regulations compared to how buildings perform in reality – both today and in the future. In particular, it considers the use of ‘real-time’ carbon factors in order to attain long-term CO2 reductions. This methodology enables decision makers to understand the impacts of different energy reduction technologies, considering each of their unique characteristics and usage profiles. If implemented, the result is a simple-to-use dataset which can be embedded into the software packages already available onto the market which mirrors the complexity of the electricity grid that is under-represented through the use of a static carbon figure.
