Published: December 2021

PurposeRisk impedes the success of construction projects in developing countries due to planning in an unpredictable and poorly resourced environment. Hence, the literature suggests that practitioners are not fully aware of how important the risk identification process is. Some of the prior studies identified risks in developing countries without highlighting how they can be beneficial to the practitioners in the industry. Therefore, this study highlights this process and identifies the key risks that affect the Jordanian construction industry.Design/methodology/approachThis study adopted an exploratory sequential mixed approach, two rounds of face-to-face interviews that were conducted in Jordan among 12 experts followed by a questionnaire randomly distributed to 122 practitioners. This study utilized the relative importance index, coefficient of variation, and Mann–Whitney (U) to analyze the data. Also, the factor analysis technique was used to identify and regroup the risk factors to further understand the correlation among the risks.FindingsThe result revealed an agreement among contractors’ and consultants’ responses toward allocating risks. Furthermore, several risks can be traced back to the project communication management process, highlighting a deficiency in the process. Also, four-factor groups were established, the first group includes the risk of defective design, late decisions making by other project participants and poor coordination with the subcontractor. The second group has only the risk of corruption, including bribery at sites. The third group includes stakeholders’ financial instability and inadequate distribution of responsibilities and risks. The fourth group includes adverse weather conditions and the use of illegal foreign labor.Originality/valueSome of the prior studies identified risks in developing countries without highlighting how they can be beneficial to the practitioners in the industry.

Authors: Alias Bity Salwana , Ishak Mohd Radzi , Nordin Muhammad Nur Asyraf 
Published: December 2021

PurposeThe main purpose of this study was to determine school leaders' ability to manage underprivileged students' needs, the level of achievement of these students and the relationship between the two variables.Design/methodology/approachA quantitative methodology comprising a questionnaire instrument was utilized to collect data from 239 underprivileged students attending schools in Kelantan, Malaysia. Descriptive statistics comprising mean values and standard deviations were calculated to determine school leaders' ability to manage underprivileged students' needs and the level of achievement of these students. Inferential statistics comprising a Pearson correlation was calculated to determine the relationship between the two variables.FindingsSchool leaders' ability to manage underprivileged students' needs was high, whereas the achievement of underprivileged students was moderate. A weak positive relationship was observed between the two variables.Research limitations/implicationsThe sample was limited to 15–16-year-old students in one state in Malaysia. Further research is therefore needed on samples from across Malaysia. This paper enhances knowledge of the relationship between school leaders' ability to manage underprivileged students' needs and the level of achievement of these students. This study also has implications for Maslow's human needs theory.Practical implicationsThe implications of the findings for school management practices are that an ability to manage underprivileged students' needs can increase the level of achievement of these students. The findings also indicate that adhering to Sustainable Development Goals, the Malaysian Education Blueprint and the Eleventh Malaysian Plan to ensure quality education for underprivileged students is relevant and should be continued. The findings can also be used as input in training school leaders.Social implicationsThe findings suggest that the community needs to take more responsibility for underprivileged students, especially in managing their needs, in order to increase the achievement. The findings can usefully be employed to reduce the social gap between underprivileged and privileged groups.Originality/valueThis is the first study to examine the relationship between school leaders' ability to manage underprivileged students' needs and the students' achievement.
Russian and UK Dementia Action Plans: a comparative analysis
Authors: Koberskaya Nadezhda , Kobierskij Bogdan 
Published: December 2021

Purpose
This study aims to compare two national dementia plans and analyse the approach of each state to the issue.

Design/methodology/approach
Comparative analysis, legal analysis, policy analysis

Findings
Although research is central to both plans, the practical implementation of the Russian and UK plans differs. The Russian action plan on dementia is advisory in nature and does not propose specific programmes for research funding. Two plans have different approach to the role of education and risk factors.

Research limitations/implications
Lack of information on Russian regional strategies does not allow to compare regional differences between two countries.

Originality/value
This study illustrates several weak points in the UK and Russian dementia policies, which should be addressed to tackle the dementia problem in both countries.
Triple vectorial analysis of financial development impact on economic growth: evidence from the Middle East and Central Asia
Authors: El Khoury Rim , Harb Etienne , Nasrallah Nohade 
Published: December 2021

PurposeThis paper provides a state-of-the-art review of the financial development in the Middle East and Central Asia (MECA) and examines its impact on its economic growth.Design/methodology/approachThe authors use a Panel Data Regression Analysis on a sample of 21 countries in MECA for the period 2008–2018.FindingsUsing the financial development indices and subindices retrieved from IMF, the study finds that the whole region has a below average index compared to other developing regions. However, this hides a great deal of variation across MECA countries. Surprisingly, financial development does not necessarily contribute to economic growth. It seems that some developing countries are still not predisposed to benefit from financial development due to several obstacles.Practical implicationsThe authors recommend policymakers and regulators in MECA to promote financial stability and keep inflation in check so that economic agents can reap the fruits of financial development and foster economic growth. Policymakers should also stimulate competition in the financial sector, build skillful human capital, attract foreign direct investments, strengthen supervision and forensic audit and more importantly reinforce the independence of central banks.Originality/valueThe authors mitigate the shortcomings of single indicators as proxies for financial development by using the IMF Financial Development index that captures the depth, access and efficiency of both financial institutions and financial markets. The authors employ lower-middle-, upper-middle and high-income country groups to test the magnitude of income level on the relationship between financial development and economic growth.
Experimental study and computational intelligence on dynamic viscosity and thermal conductivity of HNTs based nanolubricant
Authors: Wadi Valéry Tusambila , Özmen Özkan , Caliskan Abdullah , Karamış Mehmet Baki 
Published: December 2021

Purpose
This paper aims to evaluate the dynamic viscosity and thermal conductivity of halloysite nanotubes (HNTs) suspended in SAE 5W40 using machine learning methods (MLMs).

Design/methodology/approach
A two-step method with surfactant was selected to prepare nanolubricants in concentrations of 0.025, 0.05, 0.1 and 0.5 wt%. Thermal conductivity and dynamic viscosity of nanofluids were ascertained over the temperature range of 25–70 °C, with an increment step of 5 °C, using a KD2-Pro analyser device and a digital viscometer MRC VIS-8. Additionally, four different MLMs, including Gaussian process regression (GPR), artificial neural network (ANN), support vector machine (SVM) and decision tree (DT), were used for predicting dynamic viscosity and thermal conductivity by using nanoparticle concentration and temperature as input parameters.

Findings
According to the achieved results, the dynamic viscosity and thermal conductivity of nanolubricants mostly increased with the rise of nanoparticle concentration in the base oil. All the proposed models, especially GPR with root mean square error mean values of 0.0047 for dynamic viscosity and 0.0016 for thermal conductivity, basically showed superior ability and stability to estimate the viscosity and thermal conductivity of nanolubricants.

Practical implications
The results of this paper could contribute to optimising the cost and time required for modelling the thermophysical properties of lubricants.

Originality/value
To the best of the author’s knowledge, in this available literature, there is no paper dealing with experimental study and prediction of dynamic viscosity and thermal conductivity of HNTs-based nanolubricant using GPR, ANN, SVM and DT.
Predictive view of the value relevance of earnings in India
Authors: Bashir Hajam Abid , Bansal Manish , Kumar Dilip 
Published: December 2021

Purpose
This study aims to examine the value relevance of earnings in terms of predicting the value variables such as cash flow, capital investment (CI), dividend and stock return under the Indian institutional settings.

Design/methodology/approach
The study used panel Granger causality tests to examine causality relationships among variables and panel data regression models to check the statistical associations between earnings and value variables.

Findings
Based on a data set of 7,280 Bombay Stock Exchange-listed firm-years spanning over ten years from March 2009 to March 2018, the results show higher sensitivity of earnings toward cash flows, CI, divided and stock return and vice-versa. Further, the findings deduced from the empirical results demonstrate that earnings are positively related to value variables. Overall, the results established that earnings are value-relevant and have predictive ability to forecast the value variables that facilitate investors in portfolio valuation. The results are consistent with the predictive view of the value relevance of earnings. Several robustness checks confirm these results.

Originality/value
This study brings new empirical evidence from a distinct capital market, India, and provides a new facet to the value relevance debate in terms of its prediction view. The study is among earlier attempts that jointly measure the ability of earnings in forecasting different value variables by taking a uniform sample of firms at the same period. Hence, the study provides a comprehensive view of the predictive ability of reported earnings.

Authors: Tayachi Tahar , Hunjra Ahmed Imran , Jones Kirsten , Mehmood Rashid , Al-Faryan Mamdouh Abdulaziz Saleh 
Published: December 2021

Purpose
Ownership structure deals with internal corporate governance mechanism, which plays important role in minimizing conflict of interests between shareholders and management Ownership structure is an important mechanism that influences the value of firm, financing and dividend decisions. This paper aims to examine the impact of the ownership structures, i.e. managerial ownership, institutional ownership on financing and dividend policy.

Design/methodology/approach
The authors use panel data of manufacturing firms from both developed and developing countries, and the generalized method of moments (GMM) is applied to analyze the results. The authors collect the data from DataStream for the period of 2010 to 2019.

Findings
The authors find that managerial ownership and ownership concentration have significant and positive effects on debt financing, but they have significant and negative effects on dividend policy. Institutional ownership shows a positive impact on financing decisions and dividend policy for sample firms.

Originality/value
This study fills the gap by proving the policy implications for both firms and investors, as managers prefer debt financing, but at the same time try to ignore dividend payment. Therefore, investors may not invest in firms with a higher proportion of managerial ownership and may choose to invest more in institutional ownership, which lowers the agency cost.

Authors: Fikri Sofi Mohd , Naim Asmadi Mohamed , Maamor Selamah , Isa Mohamad Yazid , Ahmad Shahrul Nizam , Shari Wahidah , Muhamed Nurul Aini 
Published: December 2021

Purpose
This study aims to review the current rules and regulations on micro-takaful in Malaysia to determine whether it addresses the basic principles of micro-takaful. Although the features of the first micro-takaful are slightly different from the customary long-established takaful settings, the rules and regulations remain unchanged following the original guidelines of operating insurance and takaful. Until Perlindungan Tenang makes its first premiere, the rules and regulations on micro-takaful are gaining ground. The dissimilarity of micro-takaful from the original takaful calls for updated guidelines, so that any micro-takaful scheme launched in the market meets the demand and needs of the targeted population.

Design/methodology/approach
This study uses content analysis as the best method to review each guideline in the related rules and regulations across several documents such as microinsurance and micro-takaful discussion paper and guidelines on family takaful products.

Findings
Overall, the findings reveal that guidelines on micro-takaful operating in Malaysia support the micro-takaful requirement to be affordable, valuable, accessible, understandable and simplified. Matching the rules and regulations with this population feedback, the extended distribution channel may need further scrutiny due to deficit trust among public members toward insurance and takaful.

Originality/value
The insights presented are of important illumination to achieve long-term sustainability financial protection while preserving human well-being among those underserved.

Authors: Costa Jorge , Varum Celeste , Montenegro Mónica , Gomes João 
Published: December 2021

PurposeThe article aims to introduce the strategic question and demonstrate its relevance and reality. It also profiles the articles selected for the annual global trends issue and explains how they illustrate the various angles impacting the adoption of a new paradigm to measure tourism success.Design/methodology/approachThe paper draws on a review of articles selected to identify commonalities and differences in respect to the evolution of the concepts and methodologies explored in this global trends issue: sustainability, the contribution of tourism to host communities and measures of tourism success. A brief explanation of the positions and proposals presented by authors as well as their key contributions is also presented.FindingsThe tourism industry has traditionally been based on economics and financial return, with the metrics for measuring tourism performance remaining fairly static over the years. These placed a strong emphasis on the number of tourists and their levels of expenditure at the destinations. However, it is interesting to note a clear evolution towards a new perspective for a holistic and balanced approach between the economic, social/cultural and environmental dimensions of sustainable tourism development.Originality/valueThis introductory article sets the scene for an emerging paradigm to measure tourism success, and it highlights the various contributions to the development of sustainable tourism and the challenges faced by the tourism sector, the role of Destination Management Organizations and the need for quality data to support decision-making by public and private organizations.
Do quality incentive payments improve cooperative performance? The case of small French agricultural cooperatives
Authors: Barry Ibrahima , Rousselière Damien 
Published: December 2021

AbstractSmall agricultural cooperatives are increasingly using differentiated payments based on the quality of their members’ products. Such cooperatives make a trade‐off between the return on investment in quality and members’ disengagement from the cooperative. Based on data from the five‐year survey of small French agricultural cooperatives, we analyse the effect of incentive payments on small cooperatives’ performances. We investigate how incentive payments can reduce the problem of free riders and improve these cooperatives’ reputation. Using a quantile regression method, while controlling for the potential endogeneity of incentive payments, we show that quality‐based compensation can rule out cooperative members’ defrauding options. This remuneration has a non‐linear positive effect on small cooperatives’ performances. The results suggest that incentive payments improve small cooperatives’ performances.
Mitochondrial activity as an indicator of scallop (Mizuhopecten yessoensis) adductor muscle in early cold storage
Authors: Yin Zhongzhuan , Tian Yuanyong , Cai Yan , Qi Lin , Yuan Chunhong , Liu Junrong , Xu Tanye 
Published: December 2021

AbstractThe purpose of this study was to reveal the role of mitochondria in indicating a change in the freshness of the adductor muscle of Mizuhopecten yessoensis during cold storage and hardening. The adductor muscle hardens after 96 h of cold storage and reaches the maximum degree of hardening in 6 h. In this study, after hardening (102 h), the muscle fiber structure obviously broke and curled, and the sarcomere structure disappeared at 150 h. After hardening (102 h), the morphology of the mitochondria changed, including swelling, cristea breaking and membrane structure disappearance. The arginine phosphate content decreased gradually from the initial 4.618 to 1.306 µmol/g at 48 h, and there was no further obvious change. The ATP content decreased from 6.02 to 1.07 µmol/g in 120 h. The mitochondrial membrane potential (Δφ) was measured by a fluorescence method (JC‐1). The changes in freshness could be divided into three classes according to the Δφ difference between the mitochondria in the adductor muscle after adding ADP and CCCP. Mitochondrial function was complete from 0 to 6 h; mitochondrial function began to decline at 6 to 48 h; and mitochondrial function completely disappeared after 48 h. The results showed that the mitochondrial membrane potential compared with other indicators could more sensitively reflect the changes in freshness during the cold storage hardening process of the adductor muscle.Practical ApplicationIt is very important to interprete the post‐mortem energy metabolism for controlling the muscle quality of Yesso scallop. The K value which was developed based on ATP‐related compounds is widely used in evaluating the freshness of seafood. Mitochondria is the main sites of cellular energy metabolism and the changes of its structure and activity can sensitively reflect the quality changes in muscle cell. It is expected to develop a more sensitive freshness evaluation index.
Opiine parasitoids (Hymenoptera: Braconidae) and biological control of fruit flies (Diptera: Tephritidae) in Australia: Past, present and future
Authors: Clarke Anthony R. , Harris Colin , Kay Bianca J. , Mainali Bishwo P. , McLay Lucy K. , Strutt Francesca , Cunningham J. Paul 
Published: December 2021

AbstractOpiine braconids are parasitoids of the immature stages of frugivorous tephritids. The female wasp lays her eggs into the eggs or larvae of the fruit fly host, where the immature wasp develops before emerging as a next‐generation adult from the now dead host pupal case. In support of a new generation of Australian fruit fly parasitoid research, this paper comprehensively reviews what is known about the Australian fruit fly infesting opiines. Based on the most recent taxonomic revision 11 fruit fly infesting opiine species are documented to occur in Australia, but we consider as doubtful the record forDiachasmimorpha longicaudataand consider the record forFopius illusoriusto be tentative without further collections. We identify that the systematics and taxonomy of the Australian native fruit fly infesting opiines are in urgent need of further work. The history of fruit fly biological control in Australia is comprehensively reviewed, including the export of native Australian opiines for fruit fly control elsewhere in the world. Australia was actively involved in three major classical biological control programmes against fruit flies from the turn of the 1900s until the mid‐1960s. Despite the introduction of 11 opiine species, plus numerous other natural enemies, onlyFopius arisanusestablished in eastern Australia, where in South‐east Queensland it can now cause between 30 and 40% mean parasitism. In addition to the exoticF. arisanus, the native speciesDiachasmimorpha kraussiiandDiachasmimorpha tryonialso cause fruit fly parasitism in agriculturally important crops: both species have also been liberated widely outside of Australia for fruit fly control. Other Australian opiines have not been reared from flies infesting commercial crops and appear biologically restricted to the fruits and environs of Australian east‐coast rainforests. The biology literature forD. tryoniandD. kraussiiis comprehensively reviewed, while forF. arisanus, already reviewed elsewhere, key literature only is covered. Forward looking, we consider the potential for inoculative or inundative releases of opiines in areas where they do not currently occur to be good, while conservation biological control may help to increase the impacts of parasitoids in areas where they are already established.
