Municipal solid waste (MSW) consists mainly of several recyclable materials such as paper and cardboard. Inside the educational institutes, especially universities, MSW is generated from several facilities including offices and cafeterias. Without an effective management program, solid waste can have detrimental impacts on the environment. This paper aims to assess the solid waste management practices followed at the main campus of Imam Abdulrahman Bin Faisal University (IAU), Dammam – Saudi Arabia.

The MSW samples were collected from different sources inside the IAU campus such as the college buildings (such as the teaching rooms and staff offices), the administrative buildings and services buildings (e.g. the main library, the photocopying center, the restaurant and cafeteria) at least one time per week during a full academic term (January–May) of the academic year 2017–2018. The collected MSW samples were segregated into seven categories, and the net amount of each category and the overall weight of the MSW were determined once every week. The MSW samples were characterized for physical and chemical properties including moisture, carbon and ash contents. Food product waste (FPW) of the main university restaurant was studied separately.

Data on the composition of MSW samples revealed that 80% of wastes were recyclable, 19% as compostable materials, while only 1% of the materials were a non-recyclable waste. More than 73% of the recyclable materials include paper and plastic warranting dire need of an effective solid waste management program. The highest value of FPW was recorded for the breakfast meal.

Most of the waste generated from the university campus was recyclable type that needs to be handled carefully to avoid its mixing with other types of the waste stream. Waste characterization is an important tool that helps in understanding the amount and pattern of waste generation. It can be used as a decision-making tool for implementing sustainable waste management programs for universities.

The purpose of this paper is to assess the effectiveness of Kuwait Infection Control Directorate educational program in improving knowledge, attitude and practices (KAP) of environmental service workers (ESWs) regarding the management of infectious and sharps waste.

An interventional educational pre-test/post-test study was conducted over seven months, on a sample of 102 ESWs in Farwaniya General Government Hospital, Kuwait. Educational sessions and practical training using the KAP approach were applied during the intervention phase. The KAP of the participants were assessed using a questionnaire and observation checklist in the pre- and post-intervention phases.

Improvement in all aspects of the KAP regarding infectious and sharps waste management was observed among the participants after implementation of the intervention, with a statistically significant difference between pre- and post-test results (p<0.01).

The applied multi-component educational program in the current study can be successfully implemented for ESWs in all government hospitals in Kuwait and other countries with similar settings.

This study proposes a new framework for business process improvement (BPI) by identifying areas of improvement based on customer complaints.

The proposed framework comprises several stages. The first stage captures the voice of customer (VoC) in the form of customer complaints. The complaints are processed using text mining and sentiment analysis. Negative sentiments indicate areas for improvement by matching words with SERVQUAL dimensions. The FMEA method is used to identify business processes that need to be improved.

The opposing quality dimensions of SERVQUAL can be incorporated into a database for later identifying consumer complaints. FMEA can be used to identify potential failures in aspects that correspond to consumer complaints; therefore, improvement areas can be identified. The proposed framework, applied to a garment manufacturer, shows that the SERVQUAL dimensions, which were originally intended for service companies, can be adapted to manage customer complaints to support BPI in manufacturing companies.

The framework can be used by either the manufacturing or service industries to handle customer complaints and use the complaint analysis results to identify improvement areas to avoid the same complaints occurring in the future.

In this study, the construction of a database based on the SERVQUAL dimension to match sentiment results, where negative sentiment indicates improvement, and the use of FMEA to indicate specific business processes that should be improved is novel and has not yet been proposed by previous studies.

The purpose of this study is to investigate the roles of potential absorptive capacity (PACAP) and realized absorptive capacity (RACAP) in driving different types of innovation practices, including process, product, marketing and organizational innovation with in the supply chain (SC). Furthermore, this study also seeks to examine the previously unexplored relationship between these SC innovation practices and supply chain risk management (SCRM).

Data were collected from 267 SC professionals working in the export manufacturing industry for hypotheses testing via structural equation modeling.

The results have found that both PACAP and RACAP positively and significantly impact on each practice of SC innovation. The results also show that each SC innovation practices such as product innovation, process innovation and marketing innovation have a positive and significant impact on SCRM except organizational innovation.

This study makes a notable contribution to the broader SC management literature, with a specific focus on absorptive capacity, innovation management and SCRM, areas where empirical research is still emerging. This study reveals that organizations trying to manage SC risk must implement sufficient SC innovation practices by enhancing their PACAP and RACAP for quick response and recovery from SC disruptions.

This paper aims to enhance the stability and control of twin rotor multi-input multi-output system (TRMS) helicopters by introducing a novel approach that utilizes a multi-objective genetic algorithm (MOGA) for optimizing proportional, integral, derivative (PID) controllers in simultaneous pitch and yaw motions.

The TRMS, a common prototype for helicopter motion studies, is introduced, and a PID controller is designed for pitch and yaw stabilization. The gains of the PID controller are optimized using a MOGA, a technique not previously proposed for TRMS in the literature.

While various controllers have been explored in literature for TRMS stabilization, a MOGA-optimized PID controller for TRMS has not been proposed before. Simultaneous optimization of both pitch and yaw motions using two PID controllers is expected to yield improved robustness.

The study focuses on simulations, and experimental validation is not conducted. The MOGA is introduced as an optimization technique, and future studies may explore its application in experimental settings.

This study introduces a novel approach by utilizing a MOGA to optimize PID controller gains for TRMS. Simultaneous optimization of pitch and yaw motions aims to enhance robustness, providing a unique contribution to the field of helicopter control.

From 1979 to 2023, the takaful structure has been adopted in many jurisdictions, making the documenting of its early days of establishment relatively difficult and somewhat unreliable. This is unlike conventional insurance, where the history and legislation are well documented and archived in various research (Hellwege, 2016; Marano and Siri, 2017). The purpose of this paper is to provide a chronology for the establishment and development of takaful via the takaful establishment in each jurisdiction, documenting its first takaful operator and first takaful regulation.

This paper has used a qualitative method in the form of reviewing literature and available data such as journals, books and official resources. The data is thoroughly analysed in order to build the chronology for takaful. It adopted an exploratory research design, which is deemed suitable in situations where few works of literature have examined the subject (Neuman, 2014). The paper explores the establishment and non-establishment of takaful in 57 countries. The paper categorises the countries into seven regions starting with the GCC, Levant, Asia, Central Asia, Africa, Europe and Others.

The takaful chronology presented in this paper shows that takaful operations exist in 47 jurisdictions, starting from Sudan and the UAE in 1979, with the most recent adopters being Morocco and Iran in December 2021. It is found that 22 jurisdictions do not have takaful regulations, and the Takaful Act 1984, issued in Malaysia, is considered the first takaful regulation that sets the basis for other regulations that follow.

The paper contributes to the literature by providing a comprehensive chronology of takaful, especially as the few existing timelines have been found to be incomplete and consist of contradictory information.
