This study aims to investigate stakeholders' perception of the most prevalent unethical practices in the Ghanaian construction industry.

Data used for this study came from a cross-sectional survey (questionnaire), which was administered to 273 stakeholders in the construction industry using convenience sampling technique. The data were analyzed using statistical software package SPSSv17 to determine the most prevalent unethical practices. The ranking factor was calculated based on relative importance index (RII) value.

The results of this study reveal that corruption was perceived by major stakeholders as the most prevalent unethical behavior (RII = 0.82) followed by bribery (RII = 0.79). Political interference and kickback came third (RII = 0.77) and fourth (RII = 0.74), respectively. However, the least prevalent unethical behaviors were extortion (RII = 0.56), workplace violence (RII = 0.57), alcohol abuse (RII = 0.59) and harassment (RII = 0.59). The findings suggest that when the various groupings were taken into consideration separately, the differences in their perceptions were obvious.

Data for this study were collected from construction stakeholders in Ghana who were conveniently sampled. As a result, in reference to the sampling framework which focused on major stakeholders in only two regions of Ghana does not sufficiently ensure full generalization of the results.

The findings of the study provide significant information for construction organizations and practitioners regarding unethical practices, which are most prevalent in the Ghanaian construction industry. Construction organizations and practitioners seeking to mitigate the negative effect of unethical practices on their performance should focus on educating construction workers on how to avoid corrupt practices and report same to the authorities. Also, ethics training programs must be instituted for staff coupled with constant and random inspection and checking of ethical compliance, verbal promotion and praise for ethical conduct and in some cases increase in employees pay.

This paper is one of the first to have accessed the views of broader stakeholders, i.e. consultants, contractors, professionals, suppliers, regulators, clients and construction workers in the construction industry regarding the most prevalent unethical practices in the Ghanaian construction industry in one study. This study, therefore, enriches the current literature by providing additional dimension to the understanding of unethical practices in the Ghanaian construction industry.

The main goal of this study was to determine how students at Ho Technical University (HTU) viewed green construction approaches and the benefits green buildings may provide to Ghana's tertiary institutions to enhance quality of life.

The institution's 350 participants were chosen using a random selection method. A standardised questionnaire was used to gather data, which was analysed using SPSS v.20 and presented in tables using descriptive statistics such as Likert scale analysis, weighted mean and relative importance index (RII).

The study revealed that awareness of the green building principle is comparatively low amongst the survey participants. Participants agree that the University's green building adoption is high. Students cited decreased utility expenses, improved occupant productivity and cheaper operational costs as important benefits of green construction. Students' thoughts on hurdles to implementing green construction ideas at the University were the enormous price tag of green building technology (RII = 0.89), ignorance of demonstration projects and ignorance of information on green building principles (RII = 0.81).

This is one of the first papers to study Ghanaian students' views on green buildings. This study adds to our understanding of students' thoughts on green building ideas. In addition, it sheds insight into their present awareness, which can help the university administration in Ghana design new paths for green building implementation.

This study was conducted to identify, summarise, analyse and categorise mobile device applications (Apps), relevant to the construction industry and to explore their uses and exposure levels.

The research method involved reviewing literature and searching for Apps. The construction Apps were found by developing key phrases. These key phrases were used to develop search strategies, which were then used to find the construction Apps. The Apps found were categorised based on the similarity of their uses.

The 136 Apps identified were summarised, analysed, and categorised into 11 groups of distinct construction operations and tasks. The “Design and Drawing Apps”, “Measurement and Estimation Apps”, “Management Apps”, “All Round Apps” and “Construction Site Apps” recorded 29, 28, 26, 21 and 11 numbers of Apps, respectively. The Autodesk Sketchbook, GPS Field Area Measure, MagicPlan, Measure and TSheets were the top five in terms of the number of downloads. These Apps in terms of their exposure levels in the construction industry record 4.76%, 2.38%, 0.52%, 0.48% and 0.42%, respectively.

This paper provides a catalogue of the continuum of construction Apps for a wide variety of construction operations/activities which are available for construction professionals and provide guidance on their uses to assist in selecting appropriate Apps for specified operation/tasks/activities in the construction industry. Construction professionals may benefit from increased productivity, efficiency and ease of working.

Work-family conflict (WFC), a common problem in all sectors of every economy, has always been linked to negative consequences for individuals, families and employment organisations. However, owing to contextual and situational differences coupled with inconsistent findings, more studies on WFC are indispensable to disentangle the consequential effects of WFC, especially amongst construction professionals. More so, little is known about the dual role of project management self-efficacy (PMSE) in the WFC-performance relation. Thus, the purpose of the present study is to examine the mediating-moderating effects of PMSE on the WFC-performance nexus amongst construction professionals in a developing economy.

Data for this study came from a cross-sectional survey (questionnaire) administered to 302 construction professionals in Ghana using convenience sampling technique. And partial least square-based structural equation modelling (PLS-SEM) was performed, which included the assessment of measurement and structural models.

The results of this study support the mediating–moderating model of WFC, in which PMSE simultaneously mediates and moderates the negative influence of WFC on project performance of construction professionals; thus, validating the dual role of PMSE through the lens of Hobfoll's (1989) conservation of resource theory.

Data were collected from a conveniently sampled construction professionals in Ghana. Thus, the sampling framework, including only the construction professionals in three regions of Ghana, does not ensure the full generalisation of the results.

The findings of the study provide significant implication for construction organisations and practitioners. Construction organisations and practitioners seeking to mitigate the negative consequences of WFC on project performance should focus on building on PMSE of the construction professionals. Further, a responsive work environment is needed to cater for family needs of the construction professionals.

This paper is one of the first to have tested a model including the mediating-moderating effects of PMSE in the construction industry from a developing country perspective. The study, therefore, enriches the prevailing literature from under-represented context by examining the mediating-moderating effects of PMSE on WFC and project performance nexus that has not been previously investigated.

Encouraging employee's safety behaviour remains a challenge in the construction industry from developing countries. Several studies have examined the nexus between safety climate and safety behaviour. This paper investigates the psychological ownership as a mediator in the relationship between safety climate and occupational safety behaviours among construction professionals in Ghana.

A cross-sectional design was used for the study. Two hundred and eighty-two respondents (282) took part in the study by completing an online survey. The respondents were selected using a convenience sample technique. Data were processed using IBM SPSS version 21. The results were analysed using PLS-SEM.

Results of the study reveal that safety climate positively predicts construction professional's safety behaviour and psychological ownership. Furthermore, psychological ownership was found to (1) predict occupational safety behaviour and (2) mediate the nexus of safety climate and occupational safety behaviour.

Managers should continuously implement far-reaching policies that would promote healthy workplace safety climate and feeling of ownership among construction professionals.

This paper is one of the pioneers to have tested a model including safety climate, occupational safety behaviour and psychological ownership in a constructional profession.
