This work focusses on the crack growth behaviour of the compact tension specimen under mixed-mode loading, and numerical investigation using ANSYS Mechanical APDL 19.2 extended finite element software with different loading angles. The fatigue life is predicted under constant amplitude fatigue loading using the Paris’ law. The predicted values of the fatigue life in the present study provide consistency with the experimental and numerical results. In addition, the study showed that the direction of crack growth follows the same literature trend of experimental results. According to the results of the crack growth path, there is no effect of changing the geometries thicknesses on the crack growth trajectory. Its only effect is the resistance to higher plastic deformation which decreases as the thickness increases.

The rule based categorization approaches such as associative classification have the capability to produce classifiers rival to those learned by traditional categorization approaches such as Naïve Bayes and K-nearest Neighbor. However, the lack of useful discovery and usage of categorization rules are the major challenges of rule based approaches and their performance is declined with large set of rules. Genetic Algorithm (GA) is effective to reduce the high dimensionality and improve categorization performance. However, the usage of GA in most researches is limited in the categorization preprocessing stage and its results is used to simplify the categorization process performed by other categorization algorithms. This paper proposed a hybrid GA rule based categorization method, named genetic algorithm rule based categorization (GARC), to enhance the accuracy of categorization rules and to produce accurate classifier for text mining. The GARC consists of three main stages; namely, search space determination, rule discovery with validation (rule generation), and categorization. The experimental results are carried out on three Arabic text datasets with multiple categories to evaluate the efficiency of GARC. The results show that a promising performance was achieved by using GARC for Arabic text categorization. The GARC achieves the best performance with small feature space in most situations.

The fundamental reason for this study was to explore the impact of Supply Chain Integration on Operational Performance through the directing part of Lean Operations. The study essential information gathered from the example that contains 288 supervisors working in Saudi Industrial Organizations lied in the western locale, utilizing an all-around planned survey. This study coordinated to study how the supply chain integration, lean operations, and operational performance can impact each other in manufacturing associations. SEM model created and deliberately surveyed and tried. The key discoveries demonstrate that rehearsing supply chain integration cycles could bring about expanding the open door for manufacturing associations to accomplish operational performance through applying lean practices. Therefore, the connection between supply chain integration and operational performance, just as the connection between lean operations and operational performance, was positive, given these connections, it very well may be presumed that the lean operations (as a directing variable) can have a positive impact the connection between supply chain integration and operational performance. Particularly, the connection between supply chain integration and quality performance measures.

Supply chain management is essential for enhancing an organisation’s position among its competitors by improving its efficiency and effectiveness. The fundamental goal of this study is to recognize the effect of the supply chain responsiveness, flexibility, and its adaptation within the Saudi Arabian business industry. The data in this study were collected from a sample of 390 participants in senior business positions, and then analysed using the multiple regression technique. The results indicated that both the measurements and model have satisfactory fit indices and showed that the three hypotheses raised in this study could be accepted. Additionally, the results demonstrated that both the responsiveness and adaptation of the supply chain exert a positive effect on how the supply chain performs. So, the faster the organisation responds and adapts to the supply chain activities, the higher performance they tend to get.

Recently, Lean Six Sigma (LSS) has attracted much attention from both researchers and practitioners. In fact, many published papers used a quantitative research methodology to build and test theory in the field of LSS implementation in manufacturing area. Very few studies have been reported about the critical success factors influencing of six sigma implementations. The aim of this study is to present the results, from an empirical evidence, of Six Sigma implementation in Tunisian manufacturing. Therefore, fourteen main factors have been identified through literature review and questionnaire survey. Interpretive structural modeling (ISM) has been used to develop a hierarchical structure for analyzing the interactions among the key factors. By using the MICMAC technique, the barriers were classified into four groups according to their driving power and dependence power. Our finding provides important insight to managers and practitioners about factors in the LSS implementation process.

This paper aimed to examine a conceptual model for the relationships between hospital service quality, patient satisfaction, hospital utilization, and hospital financial performance. A total of 176 hospitals was selected from California State for this study. The standardized performance measures were used together with precisely defined specifications and standardized data collection protocols. First, an exploratory factor analysis with Varimax rotation was performed. The measurement prop-erties were then assessed in a confirmatory factor analysis (CFA). The analysis results show that quality had a significant effect on satisfaction, which, in turn, affected the financial performance. The results provide support for the previous findings indicated that service quality was positively associated with patient satisfaction and that satisfaction and utilization had a significant positive effect on financial performance. The analysis results provide support for the previous findings that hospital service quality is positively related to patient satisfaction. The findings also show that patient satisfaction and hospital utilization have a significant positive effect on hospital financial performance.

This study unraveled the effects of strategic management and organizational culture on organizational performance. It also determined the most triggering predictor of organizational performance. In this study, strategic management focused particularly on the formulation and implementation strategy. A number of 291 officers from government organizations participated in this study. Self-administered questionnaire was employed for the data collection. The analysis revealed that the performance of government organizations was impacted by organizational culture, dimensions of formulation and implementation strategy. Organizational culture emerged as the most triggering predictor on organizational performance. The study concludes with some implications for practice and theory.

Rapid economic changes and globalization have triggered urgent response from firms to devise ef-fective strategies in improving performance and ensuring long-term survival. This study examined the influence of environmental strategy and competitive advantage on business performance. Subsequently, it determined the different effects of environmental strategy and competitive advantage on business performance. This cross-sectional study involved a total of 222 hotel managers as respondents. Data in the study was obtained via self-administered questionnaires. Partial Least Squares (PLS) analysis was used to test the hypotheses of study. Findings of this study revealed the significant and positive effects of environmental strategy and competitive advantage on business performance. Competitive advantage has been found to contribute towards a higher variance on business performance than environmental strategy. Results obtained have proven the robustness of the theory applied in this study to explain the business performance of the tourism industry in the context of a developing country. The results close the gaps in previous research findings that will add to the current body of knowledge.

This study examined the relationship between Theory of Planned Behavior and knowledge sharing among nurses in Patient Computer Management System. Consequently, it determined the moderating effect of distributive justice on the relationship between Theory Planned Behavior and knowledge sharing. A quantitative approach was employed in this study. The research was based on a correlational and cross-sectional study which involved a total of 336 nurses. Data was collected based on random sampling via self-administered questionnaires. Partial Least Squares (PLS) (Version 3.0) analysis was used to analyze the data. The study revealed that Theory of Plan Behavior components were significantly related to knowledge sharing. These components were also found to have a significant and positive influence on knowledge sharing. The study revealed that distributive justice had significantly moderated the relationship between two components of Theory Planned Behavior (attitude and subjective norm) and knowledge sharing.

Students’ evaluation of quality in higher education is becoming increasingly important and widely accepted. Various researchers have reported that “high quality” education creates sustainability among students to accomplish their goals over a period of time. The intention of the present study was to explore students’ perceptions of quality in higher education in terms of curriculum content, learning and teaching experiences, institutional resources and outcome and assessment. A total of 91 students were randomly selected from the business and engineering colleges within Prince Sattam bin Abdulaziz University. The data were analyzed using descriptive and inferential statistics to obtain accurate results pertaining to the motif of the research. The findings revealed that total institutional factors emerged as one of the most prominent predictors of the outcome and assessment within the two different aforementioned disciplines. This paper concludes with suggestions for further investigation.
