Purpose This paper aims to empirically validate an integrated model, combining fuzzy analytical hierarchy processing and quality function deployment, used to construct a purchasing performance (PP) matrix for engineering procurement and construction companies (EPCs). The relationship is established by linking internal customer needs (“whats”; product-related factors), with engineering requirements (“hows”; buyer-related factors [BRFs] and organization-related factors). Three different of buying types are included: new task, straight rebuy and modified rebuy. Design/methodology/approach The paper uses qualitative and quantitative techniques to determine the factors affecting PP and the extent of their influence. Evaluation of the factors affecting the PP of EPC companies is based on 32 industry experts’ opinions, supported by the academic literature. Findings The most significant finding is that researchers should explicitly consider BRFs like buyer knowledge, which has been missing in earlier PP models. BRFs appear to be a link between different types of buying; ignoring their importance can lead to less optimized PP and erroneous findings. Originality/value This research is unique, as PP models of EPC firms have neither been published nor validated empirically, either nationally or internationally. This exploratory study adds to the body of knowledge both by identifying the emerging factors that constitute the construct of the PP of EPCs and by filling the gap between theory and practice concerning an evaluation of the PP of EPCs. Theoretical and practical implications are discussed.

Purpose – At a time when the number and seriousness of disasters seems to be increasing, humanitarian organizations find that besides their challenging work they are faced with problems caused by a high level of turnover of staff. The paper aims to discuss these issues. Design/methodology/approach – Based on the 24 variables leading to employee turnover identified by Cotton and Tuttle (1986) the authors analyse the work-related, external and personal factors affecting employee turnover in humanitarian organizations, using a survey of members of the Indian National Institute of Disaster Management. Findings – Results indicated that the three factors are present. Of the external factors, only employment perception had a factor loading over 0.7; of the work-related factors, all were significant; of the personal factors, biographical information, marital status, number of dependants, aptitude and ability and intelligence had the highest loadings. It was also shown that behavioural intentions and net expectation were not significant. Originality/value – Only a few studies reported on employee turnover and its reasons are not well understood in the context of humanitarian organizations. To address this need, the aim of this paper is to explore the personal reasons impacting employee turnover in humanitarian organizations. In the study the authors have adopted 24 variables used in Cotton and Tuttle (1986) and classified into constructs to explain turnover, and further tested the model using data gathered from humanitarian organizations.

Purpose – The purpose of this paper is to measure health-related quality of life (QOL) among patients with early stage cancer breast under curative treatment at department of oncology and nuclear medicine at Ain Shams University Hospitals. Identify factors affecting QOL among these patients. Design/methodology/approach – A cross-sectional study measured QOL among early stage female breast cancer (BC) patients and determined the main factors affecting their QOL. Three interviewer administered questionnaires were used. Findings – The physical domain mostly affected in BC patients and the functional domain least. Socio-demographic factors that significantly affected BC patients QOL scores were patient age, education, having children and family income. Specific patient characteristics include caregiver presence – a factor that affected different QOL scores. Age at diagnosis, affection in the side of the predominant hand, post-operative chemotherapy and difficulty in obtaining the medication were the disease-related factors that affected QOL scores. Originality/value – The final model predicting QOL for early stage female BC patients included age, education and difficulty in obtaining the medication as determinants for total QOL score. Carer presence was the specific patient characteristic that affected different QOL scores.

PurposeThe bid/no-bid decision is critical to the success of construction contractors. The factors affecting the bid/no-bid decision are either qualitative or quantitative. Previous studies on modeling the bidding decision have not extensively focused on distinguishing qualitative and quantitative factors. Thus, the purpose of this paper is to improve the bidding decision in construction projects by developing tools that consider both qualitative and quantitative factors affecting the bidding decision.Design/methodology/approachThis study proposes a mixed qualitative-quantitative approach to deal with both qualitative and quantitative factors. The mixed qualitative-quantitative approach is developed by combining a rule-based expert system and fuzzy-based expert system. The rule-based expert system is used to evaluate the project based on qualitative factors and the fuzzy expert system is used to evaluate the project based on the quantitative factors in order to reach the comprehensive bid/no-bid decision.FindingsThree real bidding projects are used to investigate the applicability and functionality of the proposed mixed approach and are tested with experts of a construction company in Alberta, Canada. The results demonstrate that the mixed approach provides a more reliable, accurate and practical tool that can assist decision-makers involved in the bid/no-bid decision.Originality/valueThis study contributes theoretically to the body of knowledge by (1) proposing a novel approach capable of modeling all types of factors (either qualitative or quantitative) affecting the bidding decision, and (2) providing means to acquire, store and reuse expert knowledge. Practical contribution of this paper is to provide decision-makers with a comprehensive model that mimics the decision-making process and stores experts' knowledge in the form of rules. Therefore, the model reduces the administrative burden on the decision-makers, saves time and effort and reduces bias and human errors during the bidding process.

Purpose The purpose of this study was to investigate the perceptions of construction professionals relative to factors that affect the delivery of optimum health and safety (H&S) on construction projects during the COVID-19 pandemic. Design/methodology/approach The study adopted a quantitative design which entailed the distribution of a web-based questionnaire among construction professionals, namely, architects, construction/project managers, engineers, H&S managers and quantity surveyors working for contractors and construction consultants in Zimbabwe. The data were analysed with descriptive and inferential statistics. Factor analysis was used to reveal interrelated significant sets of factors affecting the delivery of optimum H&S. Findings Factor analysis revealed nine components/factors: change and innovation-related, monitoring and enforcement-related, production-related, access to information and health service-related, on-site facilities and welfare-related, risk assessment and mitigation-related, job security and funding-related, cost-related and COVID-19 risk perception-related factors as the significant factors affecting the delivery of optimum H&S during the COVID-19 pandemic in Zimbabwe. Research limitations/implications The results highlighted the need for social dialogue among construction stakeholders to support initiatives that will enhance the delivery of H&S on construction projects. Construction stakeholders may find the results useful in highlighting the areas that need improvement to protect workers’ H&S during the pandemic. However, the small sample limits the generalisability of the results to construction sectors in other regions. Originality/value The study investigated factors affecting the delivery of optimum H&S during the COVID-19 to inform interventions to enhance H&S.

PurposeWhile operational factors reduce construction workers' productivity in Zimbabwe, the impact of the people-centred management aspects has not been empirically interrogated as a remedy. This article reports on a study that sought to determine significant people-centred management aspects that lead to improved labour productivity and assesses the existence of statistically significant differences due to the demographic variables of respondents. Demographic-specific strategies that enhance construction “workers” productivity were revealed.Design/methodology/approachThe survey research design using a self-administered questionnaire was deployed to collect the primary data. The design followed a positivist paradigm to evaluate objectively how people-centred management affects construction workers' productivity. The statistical data were descriptively and inferentially analysed.FindingsPeople-centred management was determined to be significant in improving construction workers' productivity, with the most significant aspect being the building of employee confidence in related approaches. Designations and educational levels mostly indicated a statistically significant difference in several aspects that included the adoption of a functional reward culture for workers and training on people-centred principles. Training on-site management and construction workers in people-centred management and its application are crucial to improving construction workers' productivity.Research limitations/implicationsConstruction companies should drastically improve their concern for people while they sustain a high concern for production within their construction sites. Although several factors affect construction workers' productivity, this study determined that management-related factors and people-centred management were significant towards influencing low productivity in Zimbabwe.Originality/valueThe study determined people-centred management and demographic-specific interventions as being able to improve construction workers' productivity in Zimbabwe.

Purpose The purpose of this paper is to establish the place of the printed book in the era of technological advancement with the assumption that the print media is facing imminent death in the face of readily available and convenient online information. Also the paper aims to assess how the development of new technologies have affected the production, circulation and readership of the printed book, especially among the young generation. Design/methodology/approach Explanatory study was used with closed-ended approach to collect data from 50 students of the Technical University of Kenya and 5 key informant interviews with selected book publishers in Nairobi. The uses and gratification theory was used to explore the knowledge-seeking behavior among the respondents. Findings Findings showed that more than 80% of the respondents preferred the internet to the printed book, which, according to them, has no future in the face of technological advancement. Book publishers, on the other hand, felt that the printed book has a bright future among specific audiences who are committed to it, and especially those in the rural areas who have no access to the internet. While they agreed that the internet has posed a major challenge to the sales and readership of the printed book significantly, it is helping in marketing the printed book as opposed to killing it. New bookshops in Nairobi and modern libraries in high schools, tertiary institutions and universities demonstrate that the printed book is not dying soon. Research limitations/implications The researcher experienced challenges in data collection as the respondents were busy preparing for final examinations and hence many of them were not willing to spare time to fill the questionnaire. To solve this, the researcher had to spend more time to collect data as opposed to if the students were free and ready to participate in the study without any pressure. Practical implications The findings can be used as a basis for further research to widen the scope that can help bring a wider perspective to the topic. The results can also inform policy guidelines on the topic and also contribute to the body of knowledge. Social implications The topic touches on social phenomena that are affecting a number of young people and their information-seeking habits in the era of digital revolution. The way the young generation seek and use information should be of interest not only to academic staff but also to policymakers. Originality/value The paper is original based on primary data that was collected by the researcher from the respondents. It is backed by secondary data to bridge the gap between theory and practice.

Purpose The increase in enrolment into higher education and the inadequate student housing in educational institutions has led to the growth of off-campus private student housing in Nigeria. Studentification as a research area has received attention in most countries in the global North, whereas there is dearth of studies on studentification in Nigeria. Therefore, this paper aims to examine the effects of studentification on the residents of selected Nigerian communities. Design/methodology/approach The study adopted an exploratory research strategy. Semi-structured interviews were conducted to gather qualitative data from respondents, who were landlords and indigenous tenants of the host communities of two tertiary institutions. The data collected were analysed by means of the thematic analysis technique. Findings It became evident that studentification has some effects on the communities. Significant positive effects are business patronage and liveliness, while socio-economic-related factors, which include indecent clothing and theft, were noted as the most significant negative factors. Practical implications Implementing the outcomes of this study will contribute to promoting societal ethical values and economic prosperity of the communities. Originality/value The paper contributes to building the body of knowledge on the effect of studentification in the Nigerian context.

Purpose This paper aims to investigate to what extent quality function deployment (QFD) can be used in quality improvement rather than design activities. Design/methodology/approach A framework was developed for implementation of QFD as a quality improvement tool. A case study approach is used to test this framework, and quality issues were analyzed using the framework in a ceramic tile manufacturing company. Findings The results showed considerable improvements in the critical quality characteristics identified and sales rates, demonstrating the potential of QFD to be used in assessing and prioritizing areas of improvement, and converting them into measurable process or product requirements. Research limitations/implications One case study was completed. More studies would be beneficial to support current findings. Practical implications This framework provides structured approach and guidelines for practitioners in adapting QFD for quality improvements in existing products or processes. Originality/value This study proposes a new framework to use QFD in quality improvement activities, expanding its application areas. Moreover, the results of the literature study performed provide a valuable collection of practical QFD implementation examples.
