Abstract
Purpose
Due to the need and interest of gluten-free products for celiac disease (CD) patients, the study aims to estimate the effect of the substitution of rice flour with millet flour in the presence of sweet lupin and sweet potato powder in gluten-free blends and the impact of the produced blends on gluten-free flat bread quality.
Design/methodology/approach
Seven gluten-free blends (B1, B2, B3, B4, B5, B6 and B7) were prepared with different percentages of rice flour (50–80%) and millet flour (5–35%), 10% sweet lupin and 5% sweet potato powder. Physicochemical analysis and particle size of gluten-free blends were evaluated. The resulted gluten-free bread samples were analyzed for chemical composition, color parameters and staling as well as sensory evaluation.
Findings
Results indicated that substitution of rice flour with millet flour increased protein, fat, ash, crude fiber, calcium, zinc and iron contents of flour blends, while total carbohydrates content, water holding capacity (WHC) and oil holding capacity (OHC), bulk density, L*, a* and b* values were decreased with increasing millet flour substitution. In addition, substitution with millet flour significantly increased (p < 0.05) protein, fat, ash and crude fiber contents and affected color parameters and staling of produced bread.
Research limitations/implications
As a researchers, the authors need more statistical data about type, needs, age and numbers of CD patients in worldwide and in Egypt to create a specific products for each of them. Besides, the collaboration between researchers, breeders, nutritionist and food manufactures are very vital to add new gluten-free crops.
Practical implications
New gluten-free products will be launched in markets with affordable price.
Social implications
The children with CD, especially Egyptians suffer from a shortage of varied, inexpensive and suitable gluten-free bread to achieve their needs. So the current work may help them to be satisfied.
Originality/value
Rice flour could be substituted up to 10% with millet flour without adverse effect on the sensory attributes of gluten-free bread and this may assist CD patients to discover a diversity of gluten-free blends.

Abstract
This study, completed in 1990 shortly before the Iraqi invasion, analyses some of the organizational and psychological determinants of employee turnover in Kuwait. The study is based on a sample size of 190 full‐time employees taken from governmental, private and shared sector organizations. A statistical analysis of the data indicates that organizational factors have a much more direct effect on the employee turnover rate than psychological factors. In addition, job characteristics, patterns of leadership and job motivation were the strongest predictors of voluntary job termination (employee turnover).

Abstract
Purpose
Based on the institutional theory, the purpose of this paper is to examine institutional factors that affect the development of accounting practices in Jordan.
Design/methodology/approach
The current study surveys the perceptions of 306 participants and 20 interviewees.
Findings
First, the early formation of accounting practices in Jordan has been affected by the legacy of Ottoman Empire’s and the British Colony’s accounting systems. Second, the results indicate that government of Jordan (regulatory frameworks), pressures from international donors and large economic organizations (politico-economic factors), education and training/development (cultural inputs), and the efforts to attract foreign investments and getting access into the international fund and trade (economic factors) have been influential influences in the development of accounting practices and the adoption of International Accounting Standards/International Financial Reporting Standards (IAS/IFRS) in Jordan. Finally, the findings reveal that “Secrecy” construct (a culture input) has been a problematic in the implementation of IAS/IFRS.
Practical implications
The current study provides policy implications for the Jordanian policy makers and for other developing countries that are working hard to improve the quality of financial reporting of their business entities. Finally, the authors suggest some great opportunities for future research.
Originality/value
First, this paper contributes to Jordan’s policy developments including fundamental strategies in terms of attracting foreign investments to expand the economy and the international and regional trade. Second, it fills a gap in the international accounting research by empirically assessing how institutional factors affect the development of accounting practices in emerging country such as Jordan.

Abstract
Purpose
The purpose of this paper is to assess the level of total quality management (TQM) implementation in Palestinian governmental and non-governmental hospitals using the Malcolm Baldrige National Quality Award (MBNQA) framework.
Design/methodology/approach
The study is based on collecting data using a survey questionnaire that was designed according to the MBNQA criteria. In total, 363 questionnaires from governmental and non-governmental hospitals operating in Gaza Strip were analyzed to assess the level of TQM implementation level in all hospitals (governmental and non-governmental).
Findings
The main results of this study indicate that Palestinian hospitals operating in Gaza Strip perform at a relatively acceptable level. Comparing results shows that the performance of non-governmental hospitals is better with higher degree of TQM implementation than the governmental hospitals. Detailed analysis identifies improvement opportunities-related specific aspects of the human resources focus and the performance results.
Research limitations/implications
Although this study has collected data from one Palestinian Territory, the Gaza Strip, it still identifies the critical factors and practices for TQM implementation within the Palestinian healthcare organizations to improve performance.
Practical implications
This paper suggests that business excellence models such as the MBNQA criteria can be used to assess the level of implementation of quality practices and identify the strengths and weaknesses to improve the quality of service delivery, processes, and performance of hospitals.
Originality/value
Despite the widespread use of TQM in the developed countries, little attention has been placed to implement and assess the quality initiatives by organizations in the developing countries and even fewer in low-income Arab countries (Aamer et al., 2017; Øvretveit and Al Serouri, 2006). In addition, a very few number of studies in reference to the assessment of TQM implementation in the Palestinian context, in general, and in healthcare organizations, in particular, highlight the need for this study. To move the field in that direction, the goal of this research was to assess the level of TQM implementation in the healthcare organizations (mainly hospitals) in Gaza Strip (one of the least fortunate areas of the Palestinian-occupied territories) where no prior similar research studies could be found. Therefore, this study contributes to filling this gap in the literature by providing empirical assessment of TQM level of implementation in Gaza Strip hospitals.

Abstract
Purpose
The purpose of this study is to determine whether there is a correlation between mobilization costs and project schedule performance of highway projects. In addition to this, the study will also determine if the mobilization costs are helping small or large highway projects in terms of improving the schedule performance.
Design/methodology/approach
The data of 206 highway projects were collected from the Department of Transportation of two states with the help of questionnaire survey. The cost, schedule and mobilization costs data were collected. The performance metrics related to construction schedule growth and construction intensity were developed in order to test the research hypotheses: mobilization costs will increase the schedule performance of highway projects. The data were also divided into two groups based on project cost and analyzed to check whether the mobilization costs impact the schedule performance of these highway projects. Spearman's correlation test was conducted to determine the correlation between dependent and independent variables. In addition, a Mann–Whitney test was conducted to determine the difference in medians of construction schedule growth and the construction intensity of these two groups of projects.
Findings
One major study finding was that there was no strong linear correlation between the mobilization cost percentage and the construction schedule growth and construction intensity of highway projects. However, the study found the projects that have 9% or more mobilization costs had significantly better schedule growth compared to the projects that have less than 9% mobilization costs. When data were analyzed based on the project size, it was found that this pattern was seen only in large projects costing equal to or more than $5 million.
Practical implications
This study's findings have very crucial practical implications to state DOTs contract engineers. This study shows that the highway contract engineers need to provide the right amount of mobilization costs to complete their projects on and before schedule. If the correct amount of mobilization costs is not provided to the contractors, the impact of these mobilization costs on reducing the schedule growth will be negligible. The findings of this study will assist public agency decision makers to complete their projects on or before time by including the mobilization costs provision in the contract. The state DOTs can improve their schedule performance by providing enough financial help to the contractors so that they can improve their cash flows and complete projects successfully within the given timeframe.
Originality/value
This paper contributes to the existing body of knowledge by validating the impact of mobilization costs on the schedule performance of highway projects. There has been no empirical study conducted prior to this to identify the role of mobilization costs on reducing the schedule growth of highway projects.

Abstract
Purpose
Previous studies have postulated that an advance payment system (APS) positively impacts the contractor's working capital and is paramount to ensuring an efficient and effective project cash flow process. However, scant research has been undertaken to empirically establish the cash flow performance and domino effect of APS on project and organisational performance.
Design/methodology/approach
The epistemological design adopted a positivist philosophical stance augmented by deductive reasoning to explore the phenomena under investigation. Primary quantitative data were collected from 504 Construction Industry Development Board (CIDB) registered contractors (within the grade bandings 1–9) in South Africa. A five-point Likert scale was utilised, and subsequent data accrued were analysed using structural equation modelling (SEM).
Findings
Emergent findings reveal that the mandatory use of an APS does not guarantee a positive project cash flow, an improvement in organisational performance or an improvement in project performance.
Practical implications
The ensuing discussion reveals the contributory influence of APS on positive cash flow and organisational performance, although APS implementation alone will not achieve these objectives. Practically, the research accentuates the need for various measures to be concurrently adopted (including APS) towards ensuring a positive project cash flow and improved organisational and project performance.
Originality/value
There is limited empirical research on cash flow performance and the domino effect of APS on project and organisational performance in South Africa, nor indeed, the wider geographical location of Africa as a continent. This study addresses this gap in the prevailing body of knowledge.

Abstract
Purpose
Construction companies require meticulous and thorough financial planning to ensure business survival in an increasingly competitive global market. Past studies assert that cash flow management is also crucial to meeting project and organisational performance expectations. However, the link between an advance payment system (APS), cash flow and project performance has hitherto received scant academic attention. Therefore, this study aims to investigate the attributes and impact of APS on cash flow, project and organisational performance. This study surveyed all registered contractors listed in Grades 1–9 on the Construction Industry Development Board Register of Contractors in South Africa.
Design/methodology/approach
This study adopted an empirical epistemological design and deductive reasoning to analyse primary data collated via a questionnaire data collection instrument. Summary statistical and regression analysis were used to explore data garnered.
Findings
This study found that key significant attributes of APS in South Africa were payment of balance to the contractor upon project delivery; advance payment to contractors before the commencement of the work; and payment to contractors as agreed. This study proffers that project performance in terms of cost, time and quality performance is highly and positively supported by APS. Moreover, APS positively supports the efficiency, competitiveness and profitability of construction organisations. Cumulatively, these findings confirm that APS attributes in South Africa conforms to the global attributes of APS. The research concludes that client use of APS on projects improves the likelihood of attaining improved quality and time performance. This paper concludes with a recommendation that both public and private clients consider the option of an APS as the ideal payment system to support project and organisational performance.
Originality/value
To the best of the authors’ knowledge, this work constitutes the first attempt to explore the linkages between an APS, cash flow and project performance in South Africa and seeks to engender wider polemic debate and further discussion among industry stakeholders.

Abstract
The Epidemiologic Transition can help us understand a fundamental puzzle about aging. The puzzle stems from two seemingly contradictory facts. The first fact is that death rates from noninfectious degenerative maladies – the so-called diseases of aging – increase as people age. It seems to be at odds with the historical fact that for nearly a century in which people were aging more than ever before, the aggregate rates of such diseases have been decreasing. In what sense can both be true? Crucial to resolving the puzzle are the age-profiles of such diseases in cohorts that grew up in the different regimes of the Transition. For each cohort, noninfectious diseases had increased with age, resulting in an upward-sloping age profile, which affirms the first fact. As the regimes were transitioning from the Malthusian to the modern one, however, the profiles of successive cohorts had been shifting downward: death rates from noninfectious diseases were shrinking at each age, signifying the newer cohorts’ greater aging potentials. The shifting profiles had been renewing the cohort mix of the population, shaping the century-long descent of such diseases in aggregate, giving rise to the historical fact. The profiles had shifted early in the cohorts’ adult years, associating closely with the newer epidemiologic conditions in childhood. Those conditions appear to be a circumstance under which aging potentials of cohorts could be misgauged, including in one troubling episode in the first half of the nineteenth century when the potentials had reversed.

Abstract
Purpose
This paper aims to determine the effect of the period of abandonment on the final cost and duration of resuscitated tertiary educational building projects as a basis for enhancing the performance metrics of the projects and improving the availability of facilities in tertiary institutions in Nigeria.
Design/methodology/approach
A structured questionnaire was administered on 47 professionals involved in the physical development of construction projects in Osun State public tertiary educational institutions to provide primary data for the study. Secondary data relating to initial and final costs, initial and final completion dates, dates of abandonment, period of abandonment, date of re-award, etc. were obtained from selected resuscitated projects. Data were analyzed using relative significance index and regression analysis.
Findings
The most significant effects of project abandonment were found to be disappointment of populace and over-stretching of existing facilities. The study showed a directly proportional and an exponential effect of period of abandonment on percentage cost overrun of resuscitated projects, which were represented by yc = −329.755 + 19.545x and yc = 6.1662e0.0506x, respectively. A linear relationship between period of abandonment and percentage time overrun was represented by yt = 0.467 + 0.816x.
Research limitations/implications
The fact that the regression equations could not be validated because of paucity of data was identified as a limitation of this study.
Practical implications
This study adds to the body of knowledge on abandonment of building projects from a quantitative perspective. Findings have implications for guiding long-term infrastructure development plans in public tertiary educational institutions.
Originality/value
Maximum threshold at which abandoned projects may be resuscitated at an economic cost was established as 16 months. Findings further suggest that the economy of new construction would outweigh resuscitation of abandoned projects beyond this period.

Abstract
Purpose
In most developing countries, the delivery of construction project is still characterised by inefficiencies resulting from the use of outdated methods and techniques, which retards project performance. Hence, the call for the implementation of innovative technologies such as humanoids in the execution of construction projects as it has been proven to be very effective in other sectors while improving productivity and quality of work. Consequently, this study looks at how humanoids can be used in the construction industry and what benefits they can bring.
Design/methodology/approach
The study employed a quantitative approach underpinned in post-positivist philosophical view using questionnaire as the instrument for data collection. The target respondents were construction professionals, and purposive sampling was used, while a response rate of 62.5% was gotten. The methods of data analysis were mean item score, standard deviation and one-sample t-test.
Findings
The findings revealed that humanoids can be used in progress tracking, auto-documentation and inspection and surveillance of tasks in construction activities. Also, the most important benefits of using humanoids in construction work were found to be shorter delivery times, fewer injuries and more accurate work.
Practical implications
The outcome of the study gives professionals and relevant stakeholders in construction and other interested parties' information about the areas where humanoids can be used and their benefits in construction.
Originality/value
The novelty of this study is that it is a pioneering study in South Africa on humanoids' usage in the construction industry. Also, it expands the existing borderline of the conservation of construction digitalisation for enhanced project execution.
