Data from different countries suggest a higher prevalence of anxiety, depression and suicides among manual and trade workers in the construction industry than in the general population. The present review examines the causes and effects of poor mental health and the effectiveness of interventions to improve manual and trade workers' mental health in the construction industry. It also identifies gaps in research and makes several suggestions for practice and future research.

A systematic literature review was conducted to examine and consolidate evidence reported in 54 relevant journal articles published between 2010 and 2021 on the mental health of manual and trade workers.

Three major themes emerged in the review of the 54 journal articles: causes of poor mental health, effects of poor mental health and interventions to improve mental health. The leading causes of poor mental health among construction manual and trade workers are poor work-life balance, high job demand, poor cultural norms and mental health stigma, chronic bodily pain, lack of social support, workplace injustice and job insecurity. The prominent effects of poor mental health are suicidality, drug and alcohol addiction, poor workplace safety and poor work performance. Moreover, the study found that some of the strategies recently implemented in the construction industry to improve mental health are deemed ineffective, or their effectiveness remains inconclusive.

The review's scope is limited to research on manual and trade workers, and it did not investigate the mental health of construction professionals and construction management students.

The review provides valuable insights into the causes and effects of poor mental health among manual and trade workers and the effectiveness of mental health interventions in the construction industry.

Images taken from construction site interiors often suffer from low illumination and poor natural colors, which restrict their application for high-level site management purposes. The state-of-the-art low-light image enhancement method provides promising image enhancement results. However, they generally require a longer execution time to complete the enhancement. This study aims to develop a refined image enhancement approach to improve execution efficiency and performance accuracy.

To develop the refined illumination enhancement algorithm named enhanced illumination quality (EIQ), a quadratic expression was first added to the initial illumination map. Subsequently, an adjusted weight matrix was added to improve the smoothness of the illumination map. A coordinated descent optimization algorithm was then applied to minimize the processing time. Gamma correction was also applied to further enhance the illumination map. Finally, a frame comparing and averaging method was used to identify interior site progress.

The proposed refined approach took around 4.36–4.52 s to achieve the expected results while outperforming the current low-light image enhancement method. EIQ demonstrated a lower lightness-order error and provided higher object resolution in enhanced images. EIQ also has a higher structural similarity index and peak-signal-to-noise ratio, which indicated better image reconstruction performance.

The proposed approach provides an alternative to shorten the execution time, improve equalization of the illumination map and provide a better image reconstruction. The approach could be applied to low-light video enhancement tasks and other dark or poor jobsite images for object detection processes.

This study aims to examine the impact of information communication technology-enabled work during non-working hours (ICT-enabled WNWHs), as a source of stress, on employee behavioral outcomes –in-role job performance, organizational citizenship behaviors (OCBs) that benefit organizations and OCBs that benefit individuals, through emotional responses – work exhaustion, nonwork exhaustion and organization-based self-esteem. As the coronavirus disease 2019 (COVID-19) lockdowns demonstrated that employees frequently engage in ICT-enabled WNWHs, studying stress induced by ICT-enabled WNWHs is essential for understanding employee adaptation to the work-from-home trend that emerged from COVID-19 lockdowns.

A quantitative survey comprising 1,178 employees in China was conducted, and the data reliability and validity were confirmed. Partial least squares structural equation modeling analysis was employed to test the hypotheses.

The study results empirically proved that, although ICT-enabled WNWHs had significant effects on employee behavioral outcomes, the related emotional responses were the mediators of the stress transmission mechanism that directly affected employee behavioral outcomes. Notably, work exhaustion and organization-based self-esteem partially mediate the stress transmission mechanism, while nonwork exhaustion exerts a full mediating effect.

This study proposes the stress transmission mechanism of ICT-enabled WNWHs and delineates emotional responses regarding the work environment attributes of ICT-enabled WNWHs, an approach rarely seen in prior IS studies. To our best knowledge, this study is the first to identify and empirically demonstrate organization-based self-esteem as one among the emotional responses to ICT-enabled WNWHs. Furthermore, it expands understanding of the holistic impacts of ICT-enabled WNWHs, which is lacking in information systems (IS) literature.

The unitized curtain wall system (UCWS), one of the prefabricated technologies, is increasingly attracting attention in the Hong Kong construction industry. However, this innovative technology still lacks on-site implementation in high-rise residential buildings. To promote its development, this study aims at identifying the influential factors of UCWS adoption in Hong Kong's high-rise residential buildings from a multi-stakeholder perspective.

Factors were first selected through an in-depth literature review and a semi-structured interview. Then the factors were validated through a questionnaire survey using Cronbach's Alpha Reliability Test. Next, the factors were ranked regarding their importance using mean-score ranking and standard deviation. Meanwhile, different stakeholders were clustered using an experimental factor analysis (EFA) model to find the shared preferences (namely common factors).

The result shows that reduction of construction time (B1) and insufficient site storage area (C1) are the most important factors. The six stakeholder groups were clustered into two segments. B1 and improved quality control are the shared interests. While C1 and the need of specification change are the common concerns.

There are two major breakthroughs in this study. First is the novelty of research objects. UCWS, particularly its application preference in high-rise residential buildings, has rarely been studied, yet it is urgently required. Second is the novel research perspective. The influential factors were studied from a multi-stakeholder perspective. Not only the significant factors for six specific stakeholders but also the shared preference for stakeholder groups was identified. The findings contribute to promoting UCWS more targeted, efficient and comprehensive, as well as demonstrating the collaborative possibilities of multi-stakeholders.

In this chapter, we discuss menopause transition in the workplace and its implications for workplace well-being. This is an important work-life interface topic, given the increasing number of women who will work during transition. It is also a topic that we currently know relatively little about, particularly in relation to well-being. We present findings that demonstrate both that many women experience symptoms that are bothersome at work and that these frequently have negative effects for two elements of workplace well-being, job satisfaction and health well-being. We evidence that individual/job characteristics and workplace context can either improve or worsen experiences of transition symptoms and make recommendations on how organization and HR practice can be designed to support women in menopause transition. We argue that working with line managers to create a more supportive context is one of the most important strategies to implement. Our research is situated in the UK police service and has wider relevance across the Global North, where similar demographic patterns are experienced, and in other male-dominated organizations and sectors.

This study aims to explore the relationships between knowledge management (KM) enablers, employee innovativeness (EI) and market development performance (MDP) in architecture, engineering and construction (A/E/C) firms.

A questionnaire survey is conducted to collect empirical data from A/E/C practitioners in Vietnam. First, factor analysis is used to identify KM enablers in A/E/C firms. Then, a framework which shows the links between KM enablers, EI and MDP is proposed. Structural equation modeling (SEM) is used to examine the proposed relationships.

This study identifies five constructs which can enable A/E/C firms to achieve effective KM implementation, including mutual trust and collaboration, organizational values and norms, information and communication systems, organizational policies and empowerment. Furthermore, the SEM results show that except for organizational policies, four remaining KM enablers significantly affect EI. It is also found that EI has a significant impact on MDP.

The findings could help A/E/C firms to know which KM enablers are critical to EI and provide a better understanding of the link between EI and MDP. Hence, they could make appropriate investments in KM practices to improve both EI and MDP.

The results of this study fill the gap in knowledge by empirically structuring the relationships between KM enablers, EI and MDP. Such results may provide A/E/C firms with useful information to enhance EI and MDP in today’s intensively competitive construction environments.

In the wake of COVID-19, the cruise industry is experiencing an unprecedented talent management challenge. Extant research suggests a broad range of work values that may attract job candidates to the cruise industry. The purpose of this study is to assess whether there are significant differences in the importance ratings of these work values for the millennials, compared to those of the preceding generation X.

With the support of a leading recruitment agency, the authors obtained responses to an online survey of 1,320 job candidates, of whom 830 were millennials. Using a quantitative approach, the authors asked them to assess the importance of eight work value domains. The authors ranked these domains for the millennials and for generation X and compared mean importance ratings using t-tests.

The results of this study reveal that differences between millennials and generation X in the ranking of the eight work value domains do exist. The authors did not find support for any systematic differences in terms of “extrinsic” versus “intrinsic” work values. However, the results show that the importance of “ego-driven” work values (e.g. support, development, compensation, work–life balance and comfort) is significantly higher for millennials. Conversely, for the more “altruistic” factors, there are no significant differences between the two generations.

Based on a very large sample of job candidates from the cruise industry, the results support the predictions of generational theories. The authors show that differences in work value ratings between generation X and the millennials exist. The authors also provide a novel perspective on the dimensions along which these differences materialize.

在一家领先的招聘机构的支持下, 我们对1320名求职者进行了在线调查, 其中830名是千禧一代。利用定量方法定量评估求职者八个工作价值域的重要性。对千禧一代和X一代的这些领域进行了排名, 并使用t检验重要性评分平均值。

新冠肺炎疫情后, 邮轮行业面临着前所未有的人才管理挑战。现有的研究表明, 广泛的工作价值观可能会吸引求职者进入邮轮行业。本研究的目的是评估千禧一代对这些工作价值的重要性评分与上一代X相比是否存在显著差异。

研究结果显示, 千禧一代和X一代在这八个工作价值领域的排名上确实存在差异。在“外在”和“内在”工作价值方面, 没有任何系统差异的证据支持。然而, 研究结果指出, “自我驱动”的工作价值观（如支持、发展、薪酬、工作与生活的平衡和舒适）对千禧一代的重要性明显更高。相反, 对于更“利他”的因素, 两代人之间没有显著差异。

基于邮轮行业的大量求职者样本, 结果支持代际理论的预测。研究表明, X一代和千禧一代在工作价值评价上存在差异。还提供了一个关于这些差异实现维度的新视角。

Con el apoyo de una importante agencia de contratación, se obtuvieron respuestas a una encuesta online de 1.320 candidatos a un puesto de trabajo, de los cuales 830 eran de la generación del milenio (milenials). A partir de un enfoque cuantitativo, se preguntó que evaluaran la importancia de ocho dimensiones sobre valores laborales. Se clasificaron estas dimensiones para los milenials y para la generación X y se compararon las valoraciones medias de su importancia mediante pruebas t.

A raíz del Covid-19, el sector de los cruceros está experimentando un reto de gestión del talento sin precedentes. La investigación existente sugiere una amplia gama de valores laborales que pueden atraer a los candidatos al sector de los cruceros. El objetivo de esta investigación es evaluar si existen diferencias significativas en las puntuaciones sobre la importancia de estos valores laborales para los millenials, en comparación con los de la generación X precedente.

Nuestros resultados revelan que existen diferencias entre los milenials y la generación X en la clasificación de las ocho dimensiones sobre valores laborales. No se encuentra apoyo para ninguna diferencia sistemática en términos de valores laborales “extrínsecos” frente a “intrínsecos”. Sin embargo, nuestros resultados muestran que la importancia de los valores laborales “impulsados por el ego” (por ejemplo, el apoyo, el desarrollo, la retribución, el equilibrio entre la vida laboral y personal y la comodidad) es significativamente mayor para los milenials. Por el contrario, para los factores más “altruistas” no hay diferencias significativas entre las dos generaciones.

Basándonos en una muestra muy amplia de candidatos a un puesto de trabajo en el sector de los cruceros, nuestros resultados respaldan las predicciones de las teorías generacionales. Se demuestra que existen diferencias en las valoraciones del trabajo entre la generación X y los milenials. También, se aporta una perspectiva novedosa sobre las dimensiones a lo largo de las cuales se materializan estas diferencias.

Despite its crucial role in ensuring food safety, traceability remains underutilized by small and medium-sized enterprises (SMEs), a vital component of China’s agricultural supply chain, thereby compromising the integrity of the supply chain traceability system. Therefore, this study sets out to explore the factors influencing SMEs’ adoption of traceability systems and the impact of these factors on SMEs’ intent to adopt such systems. Furthermore, the study presents a model to deepen understanding of system adoption in SMEs and provides a simulation demonstrating the evolutionary trajectory of adoption behavior.

This study considers the pivotal aspects of system adoption in SMEs, aiming to identify the influential factors through a grounded theory-based case study. Concurrently, it seeks to develop a mathematical model for SMEs’ adoption patterns and simulate the evolution of SMEs’ adoption behaviors using the Q-learning algorithm.

The adoption of traceability among SMEs is significantly influenced by factors such as system attributes, SMEs’ capability endowment, environmental factors and policy support and control. However, aspects of the SMEs’ capability endowment, specifically their learning rate and decay rate, have minimal impact on the adoption process. Furthermore, group pressure can expedite the attainment of an equilibrium state, wherein all SMEs adopt the system.

This study fills the existing knowledge gap about the adoption of traceability by SMEs in China’s agricultural supply chain. This study represents the pioneer study that identifies the factors influencing SMEs’ adoption and examines the effects of these factors on their traceability adoption, employing a multi-methodological approach that incorporates grounded theory, mathematical modeling and the Q-learning algorithm.
