Purpose – Construction waste originates from various sources, generally from the inception of construction through to the completion of a building project. Previous research has shown that there is a link between the quantity of waste generated and the way labour is organized in the construction industry. However, these studies have failed to look into the sources of waste with respect to labour utilization and how it influences the generation of waste. The purpose of this paper is to investigate the influence of labour arrangements on construction waste generation, particularly the sources of waste and the attitudes of workers. Design/methodology/approach – Using a combination of direct observations and source evaluations on six case study sites, the waste in direct and subcontracted labour (SL) arrangements was quantified. A questionnaire survey was administered to the workers participating in the observation study to elicit their attitudes to waste and closely linked issues. Findings – The results show that SL produced more waste than direct labour in all three work processes considered. A lack of organizational commitment and effective strategy emerged as the main problem in waste reduction. Practical implications – Subcontractors should be made responsible for their share of waste generated in a project. Main contractors should record who are “approved subcontractors” based on their performance at site which should include inter alia waste generation. The approved subcontractor method is a way of barring subcontractors from being included on future projects if they do not meet the performance standards of a main contractor. Originality/value – This study shows that waste generation has a relationship to organizational commitment and strategy rather than to workers’ attitudes. In order to manage construction waste effectively, it has to be considered in the financial equation of a project, because attitudinal changes are difficult to achieve unless there is a personal financial benefit attached to it.

Development of the infrastructure is favorable for the growth and economy for any country; however, the issues to manage construction waste due originating from development exercises is a noteworthy reason for concern. The waste from construction contributes to negative repercussions on time, cost, productivity, and environment. Therefore, to reduce these negative and undesirable effects, a detailed review of waste generation and management must be provided. The significant construction waste causes were identified and grouped into seven clusters: construction management, design, construction material procurement, construction material handling, construction site condition, and external factor. A total of 150 questionnaire survey forms were distributed to professionals working on the Riyadh metro project, and only 118 questionnaire forms were received. The collected data from the questionnaire is analyzed using the average index and factor analysis. Analysis identified that ‘Design errors; ‘Accidents; ‘Damage during handling’; ‘Communication problems; ‘Frequent variation orders’ ; ‘Congestion of the site’ and ‘Damage caused by workers’; are highest significant causes in each category respectively. Furthermore, factor analysis was conducted through Exploratory Factor Analysis (EFA) technique to the top fifteen (15) factors and found five factors responsible for the construction waste was identified such as management, workers issues, material related issues, improper handling, and design. The findings from this study are useful for policymakers to develop or/and enhance recommendations on construction waste generation to prevent problems in construction industries. The government or building industry should establish or strengthen regulations that regulates how construction materials should be disposed of.

Significance Levels

Rapid growth in construction activities as a result of a growing population and urbanization in many parts of the world generates a large amount of waste from construction. To reduce and manage these wastes, a comprehensive understanding of the construction waste generation factors is needed. The purpose of this study is to identify the contributing factors of construction waste in Thailand’s construction industry. The causes of construction waste were identified through an extensive literature review. A total of 28 causes of construction waste were identified and grouped into the four categories: design and documentation, material and procurement, construction method and planning, and human resources. To determine the significant level of each factor, a structured questionnaire survey was carried out to gather information from contractors about causes of construction material waste. The results show that the categories contributing to construction waste ranks as design and documentation, human resources, construction methods and planning, and material and procurement, respectively. Meanwhile, factors from each category were also determined and ranked. Design change, inattentive working attitudes and behaviors, ineffective planning and scheduling, and material storage were among the highest impact factors on construction waste generation in each category. Identifying the significance levels of waste generation factors will help the industry’s stakeholders build suitable strategies to manage construction waste more effectively.

Purpose This study aims to examine the effect of workplace learning experience and intrinsic learning motive on job satisfaction and organizational commitment. In addition, the study examined the moderating effect of intrinsic learning motives on the relationship between learning experience and job satisfaction and organizational commitment. Design/methodology/approach The current research used the Human Capital Corporate Panel survey data set, which aimed to explore how human resource development practices influence corporate performance. In all, 10,003 samples from 441 companies were used for data analysis. Findings Results indicate that taking part in workplace learning programs positively affects job satisfaction and organizational commitment. Likewise, intrinsic learning motives are also positively related to work attitudes. However, no interaction effect between the intrinsic learning motive and the learning experience was found, which may imply that an autonomous extrinsic learning motive is a better predictor for explaining job satisfaction than is a purely intrinsic learning motive within an organizational context. Originality/value Little research has examined the actual effect of workplace learning programs on employees’ attitudes regarding job satisfaction and organizational commitment. Furthermore, to the authors’ knowledge, no research has examined the moderating effect of intrinsic learning motive with workplace learning experience on employees’ positive work attitudes.

Using Data

This study examines construction waste generation and management in Taiwan. We verify the factors probable affecting the output of construction wastes by using data for the output of declared construction wastes produced from demolition projects in Taiwan in the last year, expert interviews, and research achievements in the past, and find “ on-site separation” is the factor with effects on the output of construction wastes via cross-correlation by algorithms such as K-Means and Decision Tree C5.0. It can be seen that the output (0.092(t/M3) with on-site separation or 0.329(t/M3) without on-site separation is highly correlated with the composition ratio of construction wastes and referred to as a valid conclusion.

The Relationship

Purpose This study aims to find out how corporate social responsibility (CSR) initiatives are perceived by pharmacists and how it influences employees’ organizational commitment and organizational citizenship behavior (OCB) and role of perceived supervisor support in the study. Design/methodology/approach Pharmacists of different hierarchical levels from five multinational pharmaceutical industries in Pakistan were selected as study samples. Data were collected from 136 pharmacists working in Punjab Region. PLS-SEM was used to test the hypotheses. Findings The results from this study found that CSR was a predictor of affective organizational commitment (AOC) and OCB. AOC fully mediates the relationship between CSR and OCB. While perceived supervisory support did not moderate the relationship between AOC and OCB. Pharmaceutical firms can promote commitment toward organization and OCBs by initiating CSR activities. Research limitations/implications This research is one of the innovative studies that empirically examine the predicting role of CSR and moderating role of perceived supervisory support on employees’ attitude and behaviors in the pharmaceutical companies’ context. Moreover, this research will also help the management by adopting CSR activities as core element in shaping employees attitudes and behaviors. Originality/value It is a significant study shifting the focus of research into organizational behavior context and further influences employee’s attitudes and behavior because of perceived CSR in the pharmacy industry.

PurposeThe study examined the relationship between psychological contract breach and organizational commitment and whether leader-member exchange and job embeddedness mediate this relationship.Design/methodology/approachThe study adopted a quantitative approach and is based on a sample of 298 teachers in basic schools in Accra, Ghana. Participants completed surveys with standardized measures on psychological contract breach, job embeddedness, leader-member exchange and organizational commitment. Hypothesized relationships were tested using structural equation modeling in AMOS 21.0.FindingsPsychological contract breach had a direct negative relationship with affective and normative commitment but had no significant direct relationship with continuance commitment. Psychological contract breach was indirectly related to affective and normative commitment through both job embeddedness and leader-member exchange, and indirectly related to continuance commitment through only job embeddedness.Practical implicationsFindings from the study suggest that employers' failure to fulfill their obligations to employees has significant potential cost to the organization, and underscore the need for managers, particularly in educational institutions, to institute measures to eliminate or minimize the occurrence of psychological contract breach.Originality/valueThe study contributes to research examining antecedents of organizational commitment as well as the mechanisms linking psychological contract breach to organizational commitment in the educational context.
