The European Commission has established the reference value of the social discount rate (SDR) to be used in the cost-benefit analysis according to the subdivision of the states relating to the beneficiaries of the Cohesion Fund. This criterion does not allow to adequately consider the economic, social and environmental conditions of each European states for ensuring an equitable and inclusive growth. The aimof the work is to provide an innovative methodology for assessing the “adjusted” SDR according to the socioeconomic and environmental conditions that differently affect the sustainable development of each European state.

Through the implementation of a methodological approach that consists of ordered and sequential phases and the synergic adoption of the Multi-Criteria Techniques with the Data Envelopment Analysis, a corrective coefficient of the SDR established by the European Commission is determined.

The results obtained for the 27 European states highlight how the different conditions of each of them could affect the correct choice of the SDR to be used in the Cost-Benefit Analysis.

The proposed research represents a useful reference for identifying national reference SDR values for each European state, consistent with its specificities and with the goals of inclusive growth of the countries and of social and territorial cohesion. Furthermore, the traceability of the methodology in its phases will allow to adapt the SDR to sudden events or exogenous shocks.

Construction projects, and particularly highway infrastructures, are known to be major contributors to the socio-economic growth of developing countries. However, these types of projects are infamous for being highly risky due to the interplay of numerous risk factors. This study aims to explore the key risk factors impacting on the performance of highway infrastructure projects in Nigeria from the contextual viewpoint of key industry stakeholders.

Qualitative data was collected using semi-structured interviews. Specifically, 17 in-depth expert interviews were conducted with experienced stakeholders in the highway sector of the Nigerian construction industry. The collected data was transcribed and analysed using an established coding framework (grounded on case study approach, principles of thematic analysis and saliency analysis).

Overall, 17 key risks were identified from the data analysis process, and 6 risks were recognised as the most significant, based on the combination of prevalence of occurrence and significance of the coded information. The six top risks were: change in government, corruption, cost of construction materials, inflation, project funding issues and construction project delay. However, the first two of these risks (change in government and corruption) are politically related, which is specific and unique to the setting of Nigeria and thus might be seen as discouraging indicators that could have an impact on attracting foreign investors/contractors to Nigeria.

The study addressed the gap related with identifying context-specific risk factors impeding the performance of highway projects in Nigeria from the viewpoints of industry experts. It is expected that the findings will provide a better insight into the various risk factors and thus aid relevant policymakers to provide context-specific mitigating strategies.

Cost and time are two of the primary benchmarks in which construction projects are measured. A variety of factors, however, affect cost and time on construction projects, as identified in previous research. This has led to a need for better understanding how factors affecting cost and time overruns on public construction projects can be managed more efficiently. The purpose of this paper is to address these issues.

In this study 26 factors affecting cost and time overruns on construction projects were identified, through qualitative interviews with project managers from Danish governmental agencies and through a literature review. Through principal component analyses the 26 factors were subsequently narrowed down to four primary latent factors.

The identified four latent factors affecting cost and time overruns on public construction projects were lack of quality management, lack of project pre-planning, lack of user management and lack of project management.

Previous research has focussed on increasing knowledge by identifying and ranking factors affecting time and cost performance. This has led to the identification of an overwhelming number of factors to use for managing construction projects. The present research reduced the number of factors by clustering them into key latent factors responsible for most of the deviation in performance, narrowing the scope of construction cost and time management into a few tangible key focus areas. This supports and improves fast decision-making that is necessary in a changeable environment such as construction.

The number of passengers in the aviation sector following COVID-19 has recovered in 2023 and is 5% higher than it was in 2019. The average annual growth of air travel is predicted to be 3.2% between 2019 and 2039. This means the need for aircraft maintenance, repair and overhaul (MRO) services will also increase. Moreover, the stakeholders require lower costs, higher effectiveness/market share and sustainability. These expectations can be realized only with the identification, development and implementation of new innovations while improving and optimizing the already used processes and procedures. Since only highly qualified graduates can reach these requirements, the need for profession-specific MSc and PhD level engineers has elevated significantly. The purpose of this paper is to introduce the development and implementation of a new MRO higher educational framework program in strong cooperation with enterprises and universities.

The emphasis is placed on the program’s scouting, investigation, development, realization and evaluation by defining key performance indexes and aiming for the optimal solution for all participants.

The result of this study is the establishment of a new educational framework, the reinvention of the MSc curriculum and the integration of PhD-level researchers in the industry in a way that fulfills the needs and requirements of the MRO sector. In return, it will give various benefits to all parties involved.

The novelty of this work comes from creating a new educational MSc and PhD level framework that can push the MRO industry forward and fill the gap of missing engineers in this field. Plus, the newly developed program is highly flexible and can be used by other players in the economy after making some adaptions and modifications.

It is widely accepted that one criterion for determining if a construction project is successful is whether it is completed within the expected budget. There have been advancements in the management of building projects throughout time but cost overruns remain a key concern in the construction sector internationally, particularly in emerging economies such as Ghana. This study aims to answer the question, “What are the critical success factors (CSFs) that can assist reduce cost overruns in public sector infrastructure projects in the Ghanaian construction industry?”

This study used a quantitative survey method. The questionnaire was pre-tested by interviewing 15 contractors to ascertain the validity of the content. Factor analysis and multiple regression were adopted to analyze the data.

This study discovered that the critical factors that can reduce cost overruns in construction projects in Ghana are directly linked to five themes: early contractor involvement in the project planning stage, adequate funding, good project team relations, competent managers/supervisors and project participant incentives/bonuses. This study identifies indestructible, empirically measurable important success criteria for reducing cost overruns in public building projects in Ghana.

When well thought through from the project initiation stage to completion, these critical successes can also be used to deal with damaging economic effects such as allocative inefficiency of scarce resources, further delays, contractual disputes, claims and litigation, project failure and total abandonment.

The uniqueness of this research resides in the fact that it is, to the best of the authors’ knowledge, a first-of-its-kind investigation of the CSFs for reducing cost overruns in public building projects in developing countries.

This study aims to explore the factors that influence job satisfaction among women in Jordan and contribute to the growing interest in women’s workplace happiness in the context of the Middle East.

The authors used an explanatory sequential mixed-method approach. During the first phase, 250 female respondents were surveyed from the private sector in Jordan. The authors analyzed the impact of various employment-related attributes and other variables, including educational level, position, work experience, daily work hours, income level, relationships with colleagues and supervisors and internal career opportunities on job satisfaction. During the second stage, the authors interviewed 23 supervisor female respondents and conducted a thematic analysis to explore in more depth the determinants of job satisfaction of females working in the private sector in Jordan.

The quantitative findings of this study indicate that job satisfaction is positively influenced by education level and income, while notably, it was negatively impacted by work experience and daily work hours. Relationships with colleagues and supervisors, as well as internal career opportunities, positively affect job satisfaction. The qualitative findings of the study indicate that positive corporate culture, developing subordinates, financial independence, self-worthiness, work-life balance, internal career opportunities and factors that spillover from the personal life domain contributed highly to job satisfaction.

The findings of this study can help employers in gaining a deeper understanding of the needs and behaviors of female workers in the Middle East, potentially resulting in decreased job turnover and heightened productivity.

This study offers valuable insights into the cultural dynamics at play and sheds light on the psychology of the Arab female workforce. Given the limited research on job satisfaction among women in the Middle East and the Arab world, this study holds significant importance for practitioners.

This study aims to investigate the feasibility of health cadres in Indonesia to take perinatal depression screening in the community using Edinburgh Postnatal Depression Scale (EPDS) and Whooley.

The field study involved 11 health cadres (community volunteers who assist in maternal and child health) who were trained to administrate EPDS and Whooley towards 36 pregnant and postpartum mothers in a low resource urban setting for a month. A comparison of scores from both tools, the number and type of mistakes made by the cadres, and cadres perception about the tools were combined to determine the most feasible tool for cadres in identifying depression symptoms.

The results show both tools are comparable for screening depression symptoms in mothers; however, EPDS was better at differentiating the level of symptoms. Whooley, with two case-finding questions, is simpler for cadres, whereas the EPDS is more difficult to be computed by cadres. Cadres support the implementation of such a screening, as it provides a channel for mothers to express their negative feelings.

The findings indicate Whooley is sufficient for first-level screening in the community by cadres, whereas the EPDS should be used by qualified health-care workers for further evaluation at primary health clinics.

Health cadres could potentially be trained to use standardized yet simple psychological tools. Involving trained health cadres in integrated maternal mental health services in primary health care in Surabaya, Indonesia is promising.

The use of the EPDS and the Whooley questions has not been applied in Indonesia particularly among health cadres despite their long-lasting role in primary health-care system.

Considering food waste as a global problem resulting from the wastage of valuable resources that could fulfil the requirements of malnourished people, the current research focusses on understanding consumerism’s impact on this phenomenon. Additionally, the circular economy (CE) approach can be critical in reducing food waste and promoting sustainability.

A systematic literature review was conducted using bibliometrics and network analysis. The study reviewed 326 articles within 10 years, from 2013 to 2023.

The findings reveal four prominent factors – behavioural, environmental, socioeconomic and technological – in managing food waste (FW). Reducing FW at a holistic level can benefit individuals and the environment in several ways.

Consumers are encouraged to be more responsible for their food consumption by reducing food waste, as it affects societies and businesses both economically and environmentally. This can help promote a responsible consumption culture that values quality over quantity and encourages people to make more informed choices about what they eat and how they dispose of it post-consumption. All stakeholders, including firms, the government and consumers, must examine the motives behind inculcating pro-environmental behaviour.

Addressing consumerism and the ability to decrease FW behaviour are complex issues that require a multidimensional approach. This study seeks to fill the gap in understanding consumerism and the capacity to reduce FW using the CE approach and understand the research gaps and future research trends.

Work engagement denotes to a state of positive and affective motivation of elevated power joined with high educational levels and a great concentration on occupation and it is negatively affected by psychological problems. This study aims to assess the stress and work engagement among Palestinian nurses working in intensive care units.

A cross-sectional design was adopted. A convenience sample consisting of 225 intensive care nurses from governmental hospitals was recruited to participate. Data collection used the Nursing Stress Scale and Utrecht Work Engagement Scale-9, and demographic data were used to gather data throughout the period from February 10 to March 30, 2023.

Findings demonstrated that nurses’ stress levels were high (M = 105.9 ± standard deviation [SD] = 11.91). Concerning work engagement, the nurses endorsed moderate work engagement levels with a mean of 3.7 (SD = 0.4). Regarding work engagement subscales, the mean of vigor was 3.7 (0.6), dedication with a mean of 3.7 (0.6) and absorption with a mean of 3.7 (0.6). Also, the findings showed that stress, gender and monthly income were predictors of work engagement (p < 0.05).

Despite the significant results, this study had the following limitations: the design was cross-sectional, which limits the ability to explore the cause and effect of the study variables, thus longitudinal studies are recommended. In addition, the study adopted a self-reported questionnaire based on participants’ understanding, culture and work context which could influence their responses.

The intensive care nurses had high stress levels and moderate work engagement. Stress, gender and monthly income were predictors of the work engagement. Thus, interventions should be encouraged to minimize stress, which has a significant influence on work engagement.

This study aims to validate the impact of waiting staff’s attitudes, subjective norms, and perceived behavioural control on customer dissuasion from over-ordering and identify their antecedents using an extended theory of planned behaviour.

We selected three categories of restaurants (30 in total, including fine dining, casual dining, and fast food) in Macao and Zhuhai (China) for conducting the survey using a purposive sampling approach. The respondents were waiting staff who took customers’ orders in the past three months. In total, 393 valid responses were used for a structural-equation-modelling analysis.

The results show that restaurant waiting staff’s attitudes, subjective norms, and perceived behavioural control have positive effects on their intention to dissuade customers from over-ordering. Our study further reveals that perceived behavioural control is far more influential than attitudes and subjective norms on restaurant employees’ intentions to intervene with over-ordering. We also validate seven antecedents, including environmental concern and communication for attitudes, peer influence, supervisor influence, and organisational support for subjective norms, and self-efficacy and training for perceived behavioural control.

The food-waste literature tends to focus on consumers in home and restaurant settings and has paid scarce attention to the role of restaurant waiting staff in intervening in consumers’ waste behaviours. We fill in this research gap by revealing a formation mechanism for waiting staff’s intention to dissuade over-ordering.
