TL;DR: In this paper, an empirical research aimed at examining the relationship between the safety climate and safe work behavior in construction site environments has been conducted and the results corroborate the importance of the role of management commitment, communication, workers involvement, attitudes, competence, as well as supportive and supervisory environments, in achieving a positive safety climate.
Abstract: This paper discusses empirical research aimed at examining the relationship between the safety climate and safe work behavior in construction site environments. A literature review has identified a number of independent constructs with the potential to affect the safety climate. A research model was developed based on the hypothesis that safe work behaviors are consequences of the existing safety climate, which, in turn, is determined by the identified independent constructs. A questionnaire survey was used in order to facilitate the collection of information from construction sites. The model was tested using structural equation modeling. The paper presents the results of testing the research model. The results corroborate the importance of the role of management commitment, communication, workers’ involvement, attitudes, competence, as well as supportive and supervisory environments, in achieving a positive safety climate.

TL;DR: In this article, a comprehensive literature review was deployed to generate a set of factors believed to affect project performance, and a total of 120 questionnaires were distributed to three key groups of project participants, namely owners, consultants and contractors.
Abstract: Construction projects located in the Gaza Strip, Palestine suffer from many problems and complex issues. Consequently, the objective of this paper is to identify the factors affecting the performance of local construction projects; and to elicit perceptions of their relative importance. A comprehensive literature review was deployed to generate a set of factors believed to affect project performance. A total of 120 questionnaires were distributed to 3 key groups of project participants; namely owners, consultants and contractors. The survey findings indicate that all 3 groups agree that the most important factors affecting project performance are: delays because of borders/roads closure leading to materials shortage; unavailability of resources; low level of project leadership skills; escalation of material prices; unavailability of highly experienced and qualified personnel; and poor quality of available equipment and raw materials. Based on these findings, the paper recommends that: 1) project ...

TL;DR: In this paper, the authors identify factors affecting labour productivity within building projects, and rank these factors according to their relative importance from a contractor's viewpoint, based on a survey of 45 factors considered in a survey.
Abstract: Productivity remains an intriguing subject and a dominant issue in the construction sector, promising cost savings and efficient usage of resources. Productivity is one of the most important issues in both developed and developing countries. The developed countries are aware of the importance of economic growth and social welfare. The developing countries which face unemployment problems, inflation and resource scarcity seek to utilise resources and in such a way to achieve economic growth and improve citizens’ lives. Productivity is an issue of particular importance to projects located within the Gaza Strip, as it is considered a newly‐developed area, and a huge number of projects have been planned for the near future. The aim of this research is to identify factors affecting labour productivity within building projects, and to rank these factors according to their relative importance from a contractor's viewpoint. The analysis of 45 factors considered in a survey indicates that the main factors...

TL;DR: In this article, the influence of transformational and transactional leadership behaviors on knowledge management practices and the moderating effect of organizational culture on this relationship, in the context of small-to-medium-sized enterprises (SMEs) operating in Australia.
Abstract: Purpose – The purpose of this study is to investigate the relationship between leadership behaviors and knowledge management (KM) practices. More specifically, it aims to examine the influence of transformational and transactional leadership behaviors on KM, and the moderating effect of organizational culture on this relationship, in the context of small‐to‐medium sized enterprises (SMEs) operating in Australia.Design/methodology/approach – A total of four hypotheses were proposed for testing. It also provides is a succinct review of KM basics relevant to the study, the relationship between leadership and KM, and leadership and organizational culture.Findings – The results suggest that both transformational and transactional leadership are positively related to KM practices. They also reveal that charismatic leadership and contingent reward leadership behaviors have greater influence on all the dimensions of KM practices.Research limitations/implications – A key limitation of this study is its cross‐secti...

TL;DR: Deming's theory of management based on the 14 Points for Management is described in Out of the Crisis, originally published in 1982 as mentioned in this paper, where he explains the principles of management transformation and how to apply them.
Abstract: According to W. Edwards Deming, American companies require nothing less than a transformation of management style and of governmental relations with industry. In Out of the Crisis, originally published in 1982, Deming offers a theory of management based on his famous 14 Points for Management. Management's failure to plan for the future, he claims, brings about loss of market, which brings about loss of jobs. Management must be judged not only by the quarterly dividend, but by innovative plans to stay in business, protect investment, ensure future dividends, and provide more jobs through improved product and service. In simple, direct language, he explains the principles of management transformation and how to apply them.

TL;DR: It is found that job demands such as risks and hazards and complexity impair employees' health and positively relate to burnout and that engagement motivated employees and was positively related to working safely.
Abstract: In this article, we develop and meta-analytically test the relationship between job demands and resources and burnout, engagement, and safety outcomes in the workplace. In a meta-analysis of 203 independent samples (N = 186,440), we found support for a health impairment process and for a motivational process as mechanisms through which job demands and resources relate to safety outcomes. In particular, we found that job demands such as risks and hazards and complexity impair employees' health and positively relate to burnout. Likewise, we found support for job resources such as knowledge, autonomy, and a supportive environment motivating employees and positively relating to engagement. Job demands were found to hinder an employee with a negative relationship to engagement, whereas job resources were found to negatively relate to burnout. Finally, we found that burnout was negatively related to working safely but that engagement motivated employees and was positively related to working safely. Across industries, risks and hazards was the most consistent job demand and a supportive environment was the most consistent job resource in terms of explaining variance in burnout, engagement, and safety outcomes. The type of job demand that explained the most variance differed by industry, whereas a supportive environment remained consistent in explaining the most variance in all industries.
