Search results

Metaheuristic algorithms are classified into two categories namely: single-solution and population-based algorithms. Single-solution algorithms perform local search process by employing a single candidate solution trying to improve this solution in its neighborhood. In contrast, population-based algorithms guide the search process by maintaining multiple solutions located in different points of search space. However, the main drawback of single-solution algorithms is that the global optimum may not reach and it may get stuck in local optimum. On the other hand, population-based algorithms with several starting points that maintain the diversity of the solutions globally in the search space and results are of better exploration during the search process. In this paper more chance of finding global optimum is provided for single-solution-based algorithms by searching different regions of the search space.

In this method, different starting points in initial step, searching locally in neighborhood of each solution, construct a global search in search space for the single-solution algorithm.

The proposed method was tested based on three single-solution algorithms involving hill-climbing (HC), simulated annealing (SA) and tabu search (TS) algorithms when they were applied on 25 benchmark test functions. The results of the basic version of these algorithms were then compared with the same algorithms integrated with the global search proposed in this paper. The statistical analysis of the results proves outperforming of the proposed method. Finally, 18 benchmark feature selection problems were used to test the algorithms and were compared with recent methods proposed in the literature.

In this paper more chance of finding global optimum is provided for single-solution-based algorithms by searching different regions of the search space.

Staphylococcus aureus (S. aureus), Klebsiella pneumoniae (K. pneumoniae) and Streptococcus pneumoniae (S. pneumoniae) are among the pathogens detected during Hajj pilgrimage known to cause pneumonia. This study aims to evaluate the antibacterial activity of activated carbon cloth (ACC) with Ag⁺ impregnated with zinc oxide nanoparticles (ZnO NPs) against these pathogens.

ZnO NPs were impregnated into ACC-Ag⁺ via layer-by-layer (LbL) self-assembly. Scanning electron microscope (SEM) was used to observe the fine surface morphological details of the ACC-Ag⁺-ZnO sheets. Antibacterial activity of the ACC-Ag⁺-ZnO sheets was evaluated using the disk-diffusion susceptibility assay. Allergy patch test was done to evaluate allergic reactions of the ACC-Ag⁺-ZnO sheets on human skin.

SEM micrographs showed successful impregnation of ZnO NPs into the ACC-Ag⁺ sheets. Disk-diffusion susceptibility assay results of ACC-Ag⁺-ZnO sheets against S. aureus, K. pneumoniae and S. pneumoniae showed good antibacterial activity; with 1.82 ± 0.13 mm zone of inhibition for S. pneumoniae, at a ZnO concentration of 0.78 mg mL^-1. No signs of human skin irritation were observed throughout the allergy patch test.

Results indicate that ACC-Ag⁺-ZnO sheets could potentially be embedded within surgical face masks (pilgrims’ preferred) to reduce the risks involved with the transmission of respiratory tract infections during and after mass gatherings (e.g. Hajj/Umrah, Olympics).

Given the scarcity of Takaful products to provide financial preparation for flood victims, this study aims to propose an alternative Takaful model based on Waqf principle for the flood victims in Malaysia. This study serves as an initial stage to propose the above Takaful model and discusses the theoretical background of the model, which includes identifying the suitable Islamic principles and roles of parties involve in the model framework.

To achieve the said objectives, this paper reviews previous studies, opinions of scholars and existing Takaful models that are currently offered in the market.

In an effort to alleviate the financial burden of businesses and individuals affected by flood, Takaful industry needs to offer a special Takaful scheme to the flood victims and achieve its main objective to prepare a financial protection for social well-being. There is no harm for the various institutions (Takaful operators and State Islamic Religious Council) to do collaboration in realizing the Waqf-based Takaful model to ensure it is done in its original form to achieve the maqasid Shariah.

As an Islamic entity, the objective of Takaful business should focus on assisting the society in reducing their financial burden rather than just concentrating on achieving business profit. Thus, Waqf-based Takaful model would give platform to the operators to play their role in the society.

The views discussed in this paper originally from the researchers which is done by integrating the Islamic principles and roles of all stakeholders that may involve to implement Waqf-based Takaful model mainly for risk and financial protection for the future flood victims. The proposed framework discussed in this paper is in original form as a result of literatures and market practice in Malaysia.

The internet technology becomes an essential tool for individuals, organizations, and nations for growth and prosperity. The purpose of this paper is to integrate the DeLone and McLean IS success model with task-technology fit (TTF) to explain the performance impact of Yemeni Government employees.

Questionnaire survey method was used to collect primary data from 530 internet users among employees within all 30 government ministries-institutions in Yemen. The four constructs in the proposed model were measured using existing scales. The data analysis starts with initial exploratory factor analysis, then confirmatory factor analysis and lastly structural equation modeling via AMOS.

The results showed that the proposed integrated model fits the data well. Findings of the multivariate analysis demonstrate four main results. First, actual usage has a strong positive impact on user satisfaction, TTF, and performance impact. Second, user satisfaction has a great influence on performance impact. Third, TTF has a strong positive impact on user satisfaction and performance impact. Fourth, both user satisfaction and TTF mediate the relationship between the actual usage and performance impact.

The public sector in Yemen contains three parts: Yemeni prime minister, Yemeni ministries, and government agencies. This study focuses only on the Yemeni employees among Yemeni ministries; hence the results are not necessarily generalizable. Moreover, there are biases when the researcher measures the actual Internet usage variable through asking a participant about their opinion regarding their usage because these are generally found to differ from the true score of system usage.

The findings should be very useful for the Yemeni Government in presenting the importance of information technology effects on individual efficiency and effectiveness. Therefore, the information from these findings should encourage and support the formation of future policy at the organizational level and national level. If the government utilizes these findings by setting up strategies to promote internet usage, this may, in turn, improve professional practice, personal development, and quality of working life.

This paper adds to the existing literature of information systems by combining actual technology usage, user satisfaction, and TTF to predict performance impact within the organizations. Furthermore, this study proposed a second-order model of performance impact in order to increase the power of explaining the output by the model, which contains four first-order constructs: process, knowledge acquisition, communication quality, and decision quality. The predictive power of the proposed model has a higher ability to explain and predict performance impact compared to those obtained from some of the previous studies.

Despite widespread acceptance and exponential growth of Islamic banking across many countries, research indicates some critical issues that can potentially downturn this industry. Literature suggests that like other stakeholders such as customers, some employees too have ambivalent attitude towards its concept and practices. This calls for an empirical assessment. As no such comprehensive instrument was available, this study aims to develop a scale measuring employees' attitude towards Islamic banking.

This scale development process begins with literature review pertinent to employees’ perspective in Islamic banking, followed by a series of steps critical to achieve robustness and to ensure validity and reliability of the instrument. Research methods include a detailed set of qualitative interviews, content validation, pilot testing and exploratory factor analysis with subsequent confirmatory factor analysis.

The final scale embodies five orthogonal dimensions: awareness of Islamic banking, usefulness of Islamic banking, perception of Shariah compliance, patronage towards Islamic banking and attractiveness towards Islamic banking.

This instrument may be used both by research scholars and practicing managers to measure employees’ attitude towards Islamic banking system and practices. It may also serve as a diagnostic tool to identify the areas of strength and weaknesses in the Islamic banking system as perceived by the employees themselves.

An instrument to measure employees’ attitude towards Islamic banking system is much needed as no such comprehensive instrument is available to the best of authors’ knowledge. The study attempts to fulfil this need.

The purpose of this paper is to examine the extent of environmental offences committed in Malaysia charged under the Environmental Quality Act 1974 (EQA1974).

This study used secondary data of the environmental court cases report by the Department of Environment (DOE) Malaysia from 2008 until 2016 to examine the nature of environmental offences based on the Treadmill of Production (ToP) approach.

In comparison with the GDP growth (Department of Statistic Malaysia, 2016), the findings support ToP argument that as far as the treadmill accelerates, the more would be the environmental crime committed. However, all offences charged were weighted more on the ecological additions rather than ecological withdrawn. The trend analysis showed a decreasing trend for all types of offences committed, reflecting that Malaysia's regulatory authorities are committed to fighting against environmental crime perpetrators. Therefore, all parties must be made to internalise the values of conducting business sustainably.

This paper is the first that examines the environmental offences committed in Malaysia using the ToP approach to analyse the nature of the crime committed in Malaysia associated with the growing literature of Green Criminology.

This study aims to examine the effect of task and technology characteristics on the compatibility of technology and tasks, as well as examine the reciprocal effect between the task-technology fit and the use of information systems.

The study took place in 36 star hotels from one-star to four-star hotels in some cities and districts in South Kalimantan Province. There were 24 hotels in Banjarmasin, 7 hotels in Banjarbaru and 1 hotel in each area of Banjar, Tanah Bumbu, Tabalong, Hulu Sungai Utara and Barito Kuala. The hotels chosen were those implemented the information and communication technology as supporting administrative activities to serve hotel customers. The population was the front office staff in the existing hotels as the users of the information technology. The sampling technique used in this research was the questionnaire distribution in accordance with the number of population. Data were collected from the filled questionnaires. From the 239distributed questionnaires, 164 (68.62 per cent) were returned and used as the research data.

Task characteristics and technology characteristics have a significant and positive effect on task-technology fit, in which the higher the task characteristics and technology characteristics, the higher the task-technology fit. The task-technology fit and the use of information systems are positive and reciprocal. This means that the higher the task-technology fit, the higher the use of information systems.

The originality of this study is reciprocal relationship between the variables of use with the task-technology fit. Some researchers have found the compatibility of technological tasks affecting the use of information systems, namely, Lin and Huang (2008), Norzaidi and Salwani (2009), Larsen et al. (2009), McGill and Klobas (2009), D’Ambra and Wilson (2013), Im (2014) and Chang et al. (2015). On the other hand, in task-technology fit theory, Goodhue and Thompson (1995) state that use affects the task-technology fit.

The Takāful (Islamic insurance) industry operates on the principles of Maqāṣid al-Sharī’ah, and of late, the industry has witnessed significant market growth. The purpose of this study is to develop a performance measurement model based on Maqāṣid al-Sharī’ah to evaluate the performance of Takāful firms.

A mixed-method research approach was adopted to conduct the present study. Priorities were assigned to various dimensions of the Maqāṣid model using analytic hierarchy process and by taking inputs from 18 Takāful experts. On the contrary, six experts were involved in identifying the elements and measures for the operationalization of the Maqāṣid dimensions.

Maṣlaḥa (0.359) was found to possess the highest priority, followed by Justice (0.345) and Educating Individuals (0.295). Furthermore, under Necessity, protection of religion (0.398) and protection of life (0.388) are assigned almost similar priorities. These two are followed by the protection of progeny (0.107), protection of wealth (0.058) and protection of intellect (0.047). The final outcome of this study is a hierarchical model for the evaluation of performance of Takāful firms.

The application of the performance evaluation model will provide information to the management of Takāful firms on where they stand in terms of fulfilling Maqāṣid al-Sharī’ah principles. If any firms are found to have a deficiency in a certain part of Maqāṣid components, then proper and adequate measures can be taken to ameliorate the situation.

It is necessary to have a performance evaluation model based upon Maqāṣid al-Sharī’ah to evaluate the performance of Takāful firms as these firms operate on the principles of Maqāṣid al-Sharī’ah. Because there does not exist any such model, this study fills up this gap. Details of the measures that can be used to evaluate the performance of Takāful firms are also provided.

Find out how the employees’ performance on the implementation of the hotel reservation information system. Therefore, this paper aims to examine the effect of the task-technology fit (TTF) on the use of information systems, as well as its effect on user performance and satisfaction.

This research type is explanatory research. In explanatory research, the aim is to provide an explanation related to the causal relationship between variables and hypothesis testing. The unit of analysis adopted in this study is the individual of the front office employees who use the star hotel reservation information system in South Kalimantan Province (the population is 239, and the taken are 150 samples, based on the number of indicators multiplied 5).

The higher the TTF, the higher the level of using information systems. The higher the use level of information systems, the higher the information systems user performance and vice versa in which the higher the user’s performance, the more increase the use of information systems. On the other hand, this study found that the use of information systems and user performance has no significant effect on user satisfaction.

The novelty in this study is shown in the influence between performance variables on the usage and the usage variables on the users’ performance. This study examines the importance of reciprocal usage and user performance relationships based on previous research studies that examine the relationship and that information technology (IT) usage will affect user performance. In addition, the users’ performance will affect the users’ behavior in using IT.
