The building maintenance management becomes more complicated nowadays, with several sourcing strategies springing up for building maintenance work provisions. Various studies demonstrate that the selection factors and performance measurements are both essential aspects in determining and evaluating the sourcing strategy for building maintenance management. Thus, the purpose of this paper is to examine the relationships between the selection factors and performance measurements of sourcing strategy.

The paper targeted to evaluate and analyse the perceptions of the building maintenance practitioners regarding the degree of importance of selection factors and performance measurements. Through quantitative approach, the paper adopted stratified random sampling to distribute the questionnaires to the building maintenance practitioners operating in both private and government high-rise office buildings in Kuala Lumpur.

The findings highlighted the quality factors as the most important selection group factors; meantime, the ability to fulfil client’s need and requirement as well as the ability to deliver the service with reasonable reliability and predictability are identically important performance measurements. There is a significant relationship between the selection factors and performance measurement of sourcing strategy.

This paper provides an impetus research which uncovered the sourcing practices in the industry and guided the sourcing process in determining the appropriate sourcing strategy.

This study intends to analyze the trend of walkability research over two years (2021–2022) in several aspects, including the research problem, gap and aim underlying walkability issues, research setting, the scale of analysis, the type of data, the data collection tool, the analysis method and contribution.

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) is employed to conduct a systematic literature review from three leading databases including Web of Science (WoS), Scopus and Sage.

From the review, it can be concluded that the research focuses on two aspects, namely, the built environment and people. The studies in this field are conducted at different scales of the built environment, from macroscale to microscale, including region, city, neighborhood and street-level studies that are conducted around the world including Asia, Europe and America which receive high attention from researchers. Meanwhile, the study of walkability in Australia and Africa gains less attention. It is revealed that there are four factors of walkability including land use and accessibility for macroscale which cover region, city and neighborhood, while street network and pedestrian infrastructure and facility are mainly analyzed for street-level. Most of the studies widely utilize a quantitative approach for analyzing physical walkability factors in a measurement-based approach by using certain tools/software, and a perception-based approach by using questionnaires.

The findings can assist to keep up with the rapid pace of scientific publications and help accelerate the understanding of particular ideas in the field of walkability for the planning and design practice and policy that can be used by researchers/academia, urban designers, urban planners, architects, engineers and policymakers. Also, this study hopefully could assist further research direction for the future and could add value to a more advanced way of understanding the research on walkability.

This research provides a robust framework for walkability trend analysis and a comprehensive understanding of the main ideas from the existing research on walkability worldwide.

Climate change is expected to alter the major components of hydrological regime such as streamflow and water availability. The magnitude and their impacts are still uncertain. Therefore, it is highly required to study streamflow and flood vulnerability in tropical river basins particularly urbanised basin such as Langat River Basin. This study aims to model the future streamflow of Langat River Basin due to climate change using Rainfall-Runoff Inundation (RRI) model. Daily rainfall data obtained from Department of Irrigation and Drainage Malaysia and topographic data from HydroSHEDS at 15-second resolution were used. The projected future rainfall (2075–2099) is extracted from MRI-AGCM3.2s under the worst carbon emission scenario, RCP8.5. The annual maximum series of 1-day rainfall is selected for statistical bias correction using Quantile Mapping. The General Circulation Model data were found to be greatly corrected with reasonable Nash–Sutcliffe efficiency, Percent bias and Root Mean Square Error values. The mean of maximum 1-day future rainfall in Langat River Basin is found to be inconsistent where parts of the upstream will experience an increment at about 7% while other parts decrease at 8%. Meanwhile, the rainfall at downstream area are expected to decrease at 40%. Based on RRI simulation, the future streamflow can achieve up to 92% increment.

This chapter explores the role and impact of adaptive thinking and transformational leadership in developing and leading an enabling culture that aligns with a school’s vision and mission. This chapter will also probe the varying dimensions that enable or inhibit a school culture and the tools needed to shape and maintain it including the challenges posed in the Middle East and North Africa (MENA) region. In this chapter, examples of adaptive challenges, data-driven instructions, and effective use of technology, will be referred to as one dimension of a culture that shows alignment or lack of it with the school’s vision and mission, the role and impact of transformative adaptive leadership on school’s overall culture, especially in the UAE, and MENA region. Finally, this chapter will examine the impact of adaptive and distributed leadership in leading a cultural change.

The purpose of this study was to determine the professional competency levels acquired by internal auditors in detecting unethical behaviour, to evaluate the position of internal auditors on objectivity and integrity in dealing with unethical behaviour and to examine the extent of their awareness on ethical issues in government-linked companies (GLCs).

Data were collected via questionnaires that were randomly distributed to the internal auditors of the selected GLS in Malaysia. These questionnaires were constructed from the Certified Internal Auditor (CIA) Examination Paper and The Institute of Internal Auditors (IIA) Competency Framework.

This study found that internal auditors of the GLCs had a high level of competency in performing audit engagements and were able to detect unethical practices in the companies. The majority of the internal auditors also had a high level of objectivity and integrity when faced with unethical behaviour during audit engagements.

This study provided strong evidence that the internal auditors of Malaysian GLCs strongly complied with IIA Code of Ethics. Besides, they were also aware of the unethical behaviour which occurred within their organizations. However, this study is limited to the internal auditors in GLCs, while the questions of the survey instrument are restricted to the elements of integrity, objectivity and professional competencies of internal auditors.

This study highlights the level of internal-auditor competency and adherence to the IIA’s International Standards for the Professional Practice of Internal Auditing (ISPPIA) and IIA’s Practice Guide to identify unethical behaviour within the Malaysian GLCs.

This study is original as it focusses on GLCs which did not get much attention from previous researchers, particularly the GLCs that operate in a developing country such as Malaysia.

Oil palm, natural rubber and cocoa are the three major plantation crops planted accounting for about 4.5 million hectares of cultivated land in 1995 (4.41 million hectares in 1993 (Table 1)). These crops are grown mainly for exports. But with resource‐based industrialization, a rising proportion of output is processed domestically in the manufacture of food and industrial products. Smallholder participation in the production of these crops, mainly from rural areas, is significant. Small‐holdings accounted for 83.5% of natural rubber planted area, 51% of oil palm area, and 53% of cocoa planted area. The estate sector's shares in total area and production of the three crops are declining because estates are moving out of agriculture. Estates are diversifying their output mix, in particular replacing rubber with oil palm. The shift is induced by the downtrend in rubber prices in the 1980s except for the recovery in 1988, and the observed better returns from oil palm production. On the other hand, the area of small‐holdings planted with rubber has remained relatively stable. Both cocoa and oil palm area under small‐holdings have increased.

The purpose of this paper is to review research studies on process optimisation and machine development that lead to the enhancement of final products in various aspects of the fused deposition modelling (FDM) process.

An overview of the literature, focussing on process parameters, machine developments and material characterisations. This study investigates recent research studies that studied FDM capabilities in printing a vast range of materials from thermoplastics to metal alloys.

FDM is one of the most common techniques in additive manufacturing (AM) processes. Many parameters in this technology have effects on three-dimensional printed products. Therefore, it is necessary to obtain the optimum elements, for example, build orientation, layer thickness, nozzle diameter, infill pattern and bed temperature. By selecting a proper variable range of parameters, the layers adhere strongly and building end-use products of high quality are achievable. A vast range of materials and their properties from polymers to composite-based polymers are presented. Novel techniques to print metal alloys and composites are examined to increase the productivity of the FDM process. Additionally, defects such as shrinkage and warpage are discussed to eliminate the system’s limitations and improve the quality of final products. Multi-axis and mobile machines brought enhancements throughout the process to eliminate obstacles such as staircase defects in the conventional FDM process. In brief, recent developments were identified and a summary of major improvements was discussed in this study for future research.

This paper is an overview that provides information about research and developments in FDM. This review focusses on process optimisation and obstacles in printing polymers, composites, geopolymers and novel materials. Therefore, machine characteristics were examined to find out the accessibility of printing novel materials for different applications.

The 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.

A 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.

School 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.

The 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.

The 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.

The 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.

This is the first study to examine the relationship between school leaders' ability to manage underprivileged students' needs and the students' achievement.

This study aims to examine the existence of capital structure dynamics and speed of adjustment during different economic periods. This study adds to the existing body of literature by investigating the factors influencing adjustment process toward target debt in developing economies.

By employing two-step generalized method of moment (GMM) and sensitivity analysis, the study highlights critical factors which affect firms’ adjustment mechanism for target debt.

Dynamic GMM estimations confirm the substance of past leverage on current debt, which recognizes the existence of dynamic capital structure. The findings corroborate that adjustment process is subject to trade-off between convergence rate and cost of being off-target. The fraction of financing of Pakistani firms confirms the pattern of pecking order hypothesis. The outcome of study clearly validates the significance of dynamic trade-off modeling for optimal capital structure.

As more data become available, the authors would extend this study to investigate the sectoral analysis to find how capital structure dynamics are different across sectors and how distinctive behavior of each sector differently affects the adjustment process toward target debt across each sector. In addition, sector-level and macro-economic factors could be incorporated to examine how external factors affect the firm’s speed of adjustment across sectors.

The present study provides valuable insights for banking and corporate sector, mainly in Pakistan. The companies could take into consideration the firm-level factors which affect the adjustment process toward target debt. Likewise, the borrowing and lending procedures could be advanced by complying with dynamic mechanism of speed of adjustment. Furthermore, the findings of this research provide obstinate grounds for future research.

Both the use of dynamic GMM adjustment model and sensitivity analysis along with Sargan test validate the health of instruments and values.
