A recommendation algorithm is typically applied to speculate on users’ preferences based on their behavioral characteristics. The purpose of this paper is to provide a systematic review of recommendation systems by collecting related journal articles from the last five years (i.e. from 2014 to 2018). This paper aims to study the correlations between recommendation technologies and e-learning systems.

The paper reviews the relevant articles using five assessment aspects. A coding scheme was put forward that includes the following: the metrics for the e-learning system, the evaluation metrics for the recommendation algorithms, the recommendation filtering technology, the phases of the recommendation process and the learning outcomes of the system.

The research indicates that most e-learning systems will adopt the adaptive mechanism as a primary metric, and accuracy is a vital evaluation indicator for recommendation algorithms. In existing e-learning recommender systems, the most common recommendation filtering technology is hybrid filtering. The information collection phase is an important process recognized by most studies. Finally, the learning outcomes of the recommender system can be achieved through two key indicators: affections and correlations.

The recommendation technology works effectively in closing the gap between the information producer and the information consumer. This technology could help learners find the information they are interested in as well as send them a valuable message. The opportunities and challenges of the current study are discussed; the results of this study could provide a guideline for future research.

The purpose of this study is to compare the thermal performance of two flow configurations in corrugated plate heat exchanger (CPHE): vertical flow configuration (CPHE_vert.) and diagonal flow configuration (CPHE_diag.). The study aims to determine the differences between these configurations and evaluate their respective thermal performance based on metrics such as heat transfer rates, pressure drop values and flow distribution.

The study compares the thermal performance of two flow arrangements of CPHE using identical geometrical dimensions and test conditions. Computational fluid dynamics (CFD) is employed, and a validated numerical model is used for the investigation. The comparison is based on analyzing the rate of heat transfer and pressure drop data between the two flow arrangements.

The findings indicate that the diagonal flow configuration in CPHEs offers improved flow distribution, enhanced heat transfer performance and lower pressure drop compared to the vertical flow configuration. However, the differences in general in the thermal performance of CPHE_vert. and CPHE_diag. are found to be minimal.

To the best of the author’s knowledge, this study represents the first attempt to investigate the impact of vertical and diagonal flow configurations on the thermal performance of the CPHE.

The current study focuses on the role of antecedents to prevent perceived job insecurity and mitigate its negative impacts on work-related well-being. The study examined variables of the resourceful environment (effective organizational communication and involvement), conserved resources (perceived employability and emotional exhaustion) and resource loss (job insecurity) by drawing on the Conservation of Resources (COR) theory for predicting the work-related well-being adding the moderating role of boundaryless career orientation.

A sample of 306 salespersons of pharmaceutical companies working in Pakistan was obtained. The hypothesized relationships were tested through structural equation modeling in SmartPLS.

The results confirmed showed that the organizational communication, employee involvement and perceived employability reduce the perceived job insecurity; however, the emotional exhaustion was positively related. It also confirmed the moderating effect of boundaryless career orientation on relationship of job insecurity and well-being.

To make employees engaged, the organizations are required to involve employees by sharing knowledge, information and power to make decisions, value their opinion and ensuring the employability. Further, salespersons having a preference of a boundaryless career proved to mitigate negative impact of job insecurity on work-related well-being.

Many empirical studies have identified that the perceived job insecurity is one of the major concerns affecting employee's well-being. However, few studies simultaneously have sought to prevent the perceived job insecurity among employees. The findings are important in developing the understanding that how salespersons perceive their capabilities and the work environment of the organization, this perception; resultantly, can influence their behaviors particularly the work engagement dimension of well-being.

本研究的焦點為探討導致僱員感到缺乏職業安全的成因, 對防止該感覺的產生扮演著什麼角色，並研究導致缺乏職業安全感的成因，就減少缺乏職業安全感給和工作有關的幸福感所帶來的負面影響方面扮演著什麼角色。研究應用了可預測與工作相關的幸福感的資源保留理論 (COR) ，來探討資源豐富的環境 (有效的機構溝通及參與) 、節約資源 (感知的受僱能力與情緒耗竭) 及資源耗損 (缺乏職業安全) 這些變數，並加入了無邊界職業生涯定向的調節角色。

研究樣本為在巴基斯坦工作的306名製藥公司營業員。研究人員透過SmartPLS的結構方程模型來測試各假設的關係。

研究結果確認了組織溝通、僱員參與及感知的受僱能力均會減輕職業不安全的感覺；唯情緒耗竭則成正相關。研究結果亦確認了無邊界職業生涯定向在缺乏職業安全與幸福感之間的相互關係上起著調節效應。

過去許多實證研究均已證實缺乏職業安全感是影響僱員幸福感的一個主要因素，唯很少研究會同時透過探討資源豐富的環境 (有效的機構溝通及參與) 和節約資源 (感知的受僱能力和情緒耗竭) 等變數，來嘗試防止僱員產生職業不安全的感覺。本研究的結果至為重要、因它使我們更了解營業員對自己的能力及機構的工作環境的看法、最終會影響他們的工作行為，特別是幸福感的工作投入層面。

Job insecurity is one of the most hazardous work stressors in the twenty-first century, placing employees between employment and unemployment may threaten employees’ health in the workplaces. Using a systematic review, the first aim of this study is to list the mediators and moderators of the link between job insecurity and health-related outcomes, and second, to explain and discuss the mechanisms that could explain the mediating and moderating effects.

We searched four databases (Science Direct, PubMed, Springer Link and Google Scholar) from 2008 to 2018 to detect these mediators and moderators. Also, as the study was conducted during COVID-19 pandemic, we particularly searched and reported the same associations over this period (2019–2022).

The results of the review suggest that job insecurity negatively influences a wide range of both health- and safety-related outcomes in the workplace. The results also showed that the most studied mediator and moderator of the job insecurity-health link over the past 10 years has been workload and employability. During COVID-19, the number of studies on mediators were more than moderators and coping strategies appeared to gain more research attention. Additionally, this review suggests that, to explain the mediation and moderation effects, a combination of cognitive appraisal theory and the conservation of resources theory can be used.

Although this review suggests that job insecurity detrimentally influences employee health, the severity of this impact on health-related outcomes may vary by the effects of various moderators.

This study aims to provide an overview of the past two decades of lifelong learning (LLL) policies for enhancing employability and reduce social exclusion in young people of European countries through the development of the so-called LLL key-competences.

Built on a quasi-systematic review, this contribution explores traditional and new methods for promoting the LLL transition, and then employability, in young adults (e.g. apprenticeship, vocational training, e-learning, etc.).

It argues the need to identify all the possible approaches able to support policymakers, as they can differently impact key-competence development.

Finally, based on the consolidated EU policy experience, we propose a strategy of implementation of the LLL programmes that facilitates the institutions’ decision processes for policy-making through the use of decisional support system.

The purpose of this paper is to identify the best hostel practices and trends, and to evaluate and discuss how they are keeping up with the present demand created by the Millennials market.

Methodological approach is based on two complementary qualitative methods: ethnographic participant observation and netnography. Portuguese hostels are the target of this study, as they are considered some of the best in the world. First, a fieldwork was conducted in three top-rated hostels in Lisbon, aiming to immerse in hostel’s environment. Then, 300 online reviews were analysed to identify what customers value the most in those services. Data interpretation was done through a content analysis crossing supply-demand perspectives.

Results indicate that, while staying in a hostel, the Millennials want to: meet people, engage in activities and events, have local experiences, feel comfortable/at home, get good value for money and enjoy the convenience. In return, hostels play an important role in hospitality industry by pleasing the Millennials, by offering: central location, an interactive atmosphere, functional facilities, well-planned design and decoration, a set of activities and events and personal treatment.

This paper is one of the few to describe Millennials’ travel behaviour towards hostels’ services.

By merging good countryside and rural capitals frameworks, a model for reimagining the island's development is formulated, which is then applied to the female perspective to provide valuable insights from a group that is often marginalized in rural areas. As Croatian islands are highly tourism-oriented, this study finds it important to explore possibilities for future island development that can provide balanced and vibrant settlements on the islands.

The present paper synthesizes Shucksmith's (2018) model of a good countryside, which serves as a goal, with Gkartzios et al.'s (2022) capitals framework, which is viewed as a means of attaining a good countryside, specifically a good island. The research is delimited to the island of Brac, Croatia. By conducting interviews with female respondents, this study aims to capture the female perspective on envisioning potential futures of “good” island living, a perspective that is frequently underestimated despite its significant contributions to the creation of an ideal locale.

The results demonstrate that there is a substantial amount of socio-cultural rural capital that is leveraged to strengthen relatedness and rights as development objectives. However, low levels of economic, built and land-based rural capital pose challenges to achieving repair and re-enchantment, which are crucial for settlements that rely on tourism.

These findings bear immense implications for policymakers and planners, underscoring the imperative to account for the perspectives and needs of diverse social groups, including women, in the design and implementation of development strategies for islands. By doing so, a sustainable and equitable future, rich in tourism potential, can be cultivated on the island.

Throughout human history, the occurrence of disasters has been inevitable, leading to significant human, financial and emotional consequences. Therefore, it is crucial to establish a well-designed plan to efficiently manage such situations when disaster strikes. The purpose of this study is to develop a comprehensive program that encompasses multiple aspects of postdisaster relief.

A multiobjective model has been developed for postdisaster relief, with the aim of minimizing social dissatisfaction, economic costs and environmental damage. The model has been solved using exact methods for different scenarios. The objective is to achieve the most optimal outcomes in the context of postdisaster relief operations.

A real case study of an earthquake in Haiti has been conducted. The acquired results and subsequent management analysis have effectively assessed the logic of the model. As a result, the model’s performance has been validated and deemed reliable based on the findings and insights obtained.

Ultimately, the model provides the optimal quantities of each product to be shipped and determines the appropriate mode of transportation. Additionally, the application of the epsilon constraint method results in a set of Pareto optimal solutions. Through a comprehensive examination of the presented solutions, valuable insights and analyses can be obtained, contributing to a better understanding of the model’s effectiveness.

This study aims to explore nursing home and home care managers’ strategies in handling the COVID-19 pandemic.

This study has a qualitative design with semistructured individual interviews conducted digitally by videophone (Zoom). Eight managers from nursing homes and five managers from home care services located in a large urban municipality in eastern Norway participated. Systematic text condensation methodology was used for the analysis.

The managers used several strategies to handle challenges related to the COVID-19 pandemic, including being proactive and thinking ahead in terms of possible scenarios that might occur, continuously training of staff in new procedures and routines and systematic information sharing at all levels, as well as providing different ways of disseminating information for staff, service users and next-of-kins. To handle staffing challenges, managers used strategies such as hiring short-term staff that were temporary laid off from other industries and bringing in students.

The COVID-19 pandemic heavily affected health-care systems worldwide, which has led to many health-care studies. The situation in nursing homes and home care services, which were strongly impacted by the pandemic and in charge of a vulnerable group of people, has not yet received enough attention in research. This study, therefore, seeks to contribute to this research gap by investigating how managers in nursing homes and home care services used different strategies to handle the COVID-19 pandemic.
