Abstract
Purpose
This research presents a framework that allows project managers to predict the next critical paths (CP(s)) and to take extra care when planning and executing those activities that have the potential to cause changes in a project's current CP(s).
Design/methodology/approach
The method presented here is based on an assessment of each activity's contribution to the overall schedule variance, which involves assigning a probability distribution function to each activity duration in the project. A sensitivity analysis is also carried out, which forms the basis of identifying which activity most affects the project completion date and therefore will have the greatest effect in changing the CP.
Findings
The authors’ analysis reveals that the most appropriate probability density function (PDF) for the targeted project is the normal distribution. However, the aim of this work is not to determine the most suitable distribution for each activity but rather to study the effect of the activity distribution type on the CP prediction. The results show that the selection of the appropriate probability distribution is very important, since it can impact the CP prediction and estimated project completion date.
Originality/value
This research work proposes a delay analysis scheme which can help the project manager to predict the next CP and to improve performance by identifying which activity is the bottleneck. On the other hand, the simplicity arises from the fact that this method does not require any expensive machines or software to generate results.

Abstract
In a global context characterised by a growing recognition of the role that educational leaders play in ensuring school effectiveness and the consequent need to design effective leadership preparation programmes, many educational leadership preparation providers around the world have borrowed international standards and frameworks in order to guide their programmes and assure their quality. This trend has been on the rise as a response to globalisation pressures and a growing interest in acquiring international recognition through accreditation agencies. However, this raises important questions about the potential repercussion of using foreign, mainly Western, frameworks to develop or assess national leadership preparation provision. Evidence from relevant literature indicates that these frameworks, when applied to local contexts, need to take contextual factors into account. In this chapter, we engage with existing literature in relation to leadership preparation, internationalisation and professional standards to reflect on our experience of using international standards to develop the Masters in Educational Administration programme offered by Sultan Qaboos University (SQU) in Oman. We hope to contribute to existing internationalisation literature by providing a different perspective on educational administration and leadership preparation from a non-Western tradition, thereby expanding the understanding of meaningful leadership preparation in general.

Abstract
Purpose
The purpose of this paper is to investigate the main organizational factors that contribute to the successful implementation of business process reengineering (BPR) in the Egyptian banking sector. These factors include management commitment, information technology (IT) infrastructure, people management, change readiness, centralization and formalization.
Design/methodology/approach
The key organizational enablers were identified through an extensive literature review. Then, statistical analysis was carried out based on data collected, using a questionnaire instrument, from 184 managers employed in 38 banks operating in Egypt.
Findings
The results of the study indicate that management commitment, IT infrastructure, people management, change readiness and organizational structure with a low degree of formalization are critical enablers for implementing a successful BPR program within the Egyptian banking sector.
Practical implications
The results may support managers of banks in identifying and assessing the influence of integrating organizational factors that facilitate or hinder the successful implementation of BPR.
Originality/value
Since 2004, the Egyptian banking system has involved in major reform programs and many BPR efforts. Much research effort is required to investigate the BPR projects within the Egyptian banks in order to develop a concrete base of knowledge and understanding of the nature of BPR and factors that support its successful implementation. Moreover, there is an insufficiency of empirical studies regarding the implementation of BPR within the Egyptian service sector. The current study fills this gap by exploring and examining the main organizational factors affecting BPR implementation in a developing country.

Abstract
Purpose
Indoor environmental quality (IEQ) in buildings has an impact on people’s health, productivity and comfort. Maintaining the highest possible IEQ level in complex buildings, such as health care, is difficult due to economic and organizational constraints. This study aims to categorize the vicinities in a typical health-care facility in terms of importance and criticality in relation to the various IEQ factors, as well as to develop an IEQ assessment procedure.
Design/methodology/approach
A comprehensive literature review, established standards and structured interviews with industrial hygiene professionals in health-care settings were used in this study. To test the applicability of the developed IEQ assessment procedure, a pilot study was conducted in an existing health-care facility.
Findings
This study categorized health-care facilities into various vicinities and discovered three respondents group had varying IEQ perceptions (facility managers, environmental health specialists and nurses). According to the findings, indoor air quality is the most important and dominant factor influencing overall IEQ in health-care facilities. The trial application of the framework shows that much work is needed to improve the level of response and readiness of facility management and occupants to allow for the effective use of the developed procedure.
Originality/value
Previous research did not include a detailed categorization of vicinities in health-care buildings based on IEQ requirements. The findings of this study will help to close this knowledge gap and guide facility managers and operators in recognizing the relative importance of different IEQ factors, maintaining functional requirements and identifying priorities when developing maintenance and operational procedures and allocating resources.

Abstract
Purpose
Seasonal influenza epidemics accounted for significant morbidity and mortality loads worldwide despite the availability of a safe vaccine as an efficient tool against severity of the disease. However, the uptake of the latter was sub-optimal. This study aims to identify predictors and barriers related to seasonal influenza vaccine uptake in the Kingdom of Bahrain.
Design/methodology/approach
A cross-sectional study enrolled 502 individuals attending primary healthcare centers in Bahrain for ambulatory care between July and August 2022. The data were collected using an interviews-based questionnaire which included questions on demographic data, knowledge and attitudes and practices toward influenza vaccine. The authors identified the barriers as well as the determinants of the vaccine uptake and its recommendation to others.
Findings
The mean age of participants was 35.07 years (SD = 13.9). Most of the respondents were Bahraini (86.5%) and 53.4 % were females. The results revealed that 34.1% have previous information about the influenza vaccine and 36.9% versus 69.9% are willing to receive the vaccine or advice it to others, respectively. Determinants of vaccine uptake were identified.
Originality/value
This study confirmed a sub-optimal influenza vaccine acceptance in the general community of Bahrain despite a global access in primary care. Health professionals need to be more proactive in mobilizing the community and particularly females toward influenza vaccination.

Abstract
Purpose
The purpose of this paper is to determine the prevalence of general and abdominal obesity among adolescents attending independent schools in Qatar.
Design/methodology/approaches
A school-based cross-sectional study was conducted in November-December 2013 in 23 secondary schools. A total of 1,161 students aged 14 to 19 year olds were randomly selected using a multistage stratified cluster random sampling technique. Body weight, height and waist circumference (WC) were measured using standard protocol. The International Obesity Task Force (IOTF) age- and sex-specific body mass index (BMI) reference were used to define overweight and obesity. Abdominal obesity (AO) was defined by waist to height ratio (WHtR ≥ 0.5) and by sex- and age-specific WC cut-off values.
Findings
The prevalence of overweight and obesity among the study population was 20.6 and 20.7%, respectively. The highest rate of overweight and obesity was observed among boys, and the youngest age group. The rate of obesity defined by either WC/or WHtR was higher than that assessed by BMI. The prevalence of AO assessed by WC and WHtR was 48.8 and 46.9%, respectively. The rate of AO was significantly higher (p < 0.05) among boys compared to girls for both assessment criteria. The proportion of adolescents with AO (WHtR ≥ 0.5) according to BMI was 17.3%, 80.8% and 97.1% for adolescents with normal, overweight and obesity had AO, respectively. Being male was significantly associated with higher odds of having both general obesity and AO.
Originality/value
The study revealed a high prevalence of general and abdominal obesity in adolescents in Qatar. Waist measures appear to be an important indicator in identifying adolescents at risk and should be included as screening tools for cardiometabolic risk.

Abstract
The purpose of this chapter is to shed light on humanistic knowledge traditions and highlight their value in informing educational administration and leadership curricula designed for graduate students. We argue that, despite their distinctive features, humanist traditions such as the Confucian, Buddhist, Islamic and European share many core values and practices that should be incorporated into the educational administration and leadership curricula. However, these traditions tend to be overlooked or marginalised by curriculum designers. We argue that incorporating these traditions into educational administration and leadership curricula can contribute to greater internationalisation and achieve a greater diversity. The chapter starts with an exploration of the origins, nature and definitions of humanism. The following parts discuss Confucian, Buddhist, Islamic and European humanist traditions and examine how they can contribute to shaping educational administration and leadership curricula.

Abstract
Purpose
This paper intends to review and assess the factors influencing adaptive reuse of commercial projects, throughout their life cycle, in Saudi Arabia.
Design/methodology/approach
A mixed approach of literature review, pilot-testing and questionnaire survey was utilized to identify and assess the factors affecting adaptive reuse of commercial projects. Thirty-eight factors were identified and categorized under four groups, corresponding to the key phases of the project life cycle. The questionnaire survey was administered to a targeted group of 90 architecture/engineering, construction and facilities management (AEC/FM) practitioners of building adaptive reuse, in the Eastern Province of Saudi Arabia. The relative importance index (RII) for each factor was calculated. Three levels of agreement, based on the ranking of the factors, among the respondents were determined.
Findings
The most important factors affecting adaptive reuse of commercial projects are: structural integrity of the building, municipal approval for the land use change, enforcement of safety procedures at the project site, compliance with health and safety measures and accuracy and completeness of the contract documents. A high level of agreement was observed among the three groups of respondents, on the ranking of the factors.
Originality/value
This research expands the body of knowledge, through providing AEC/FM practitioners, with the type, importance and ranking of the influential factors on adaptive reuse of commercial projects, throughout their life cycle.
