This paper proposes a new variant of NTRU with a slightly different critical formulation. The significance of this new variant is that it requires an additional private key to provide a tighter scheme. Because of these changes, modified key generation, encryption and decryption algorithms have been developed accordingly. The new variant is analyzed and tested against several well-known attacks, namely the alternate private key attack, brute force attack, meet-in-the-middle attack, multiple transmission attacks and lattice attack. Security properties related to these attacks have been established and explored to ensure the new variant is secure against the said attacks. Several examples are provided to illustrate the ideas.

A new method of amidation of Carboxy Multi Walled Carbon Nanotubes (MWCNT-COOH) with diamine monomer such as ethylene diamine (EDA) and O-Phenylenediamine (OPDA) was applied by using a solution blending technique. The structure and properties of these composites have been investigated by FTIR, SEM, TEM, XRD, UV, DSC and TGA. The formation of Poly [MWCNT/ Amide] composites was confirmed and the DC electrical conductivity of poly-composites was in the range 4.5×10^-6-5.3×10^-6 S/cm due to the interaction between the nanotubes.

In this era of industrialization, there is an increase rate of e-logistic services, which has raised the necessity to pay more attention on e-logistic customer satisfaction. E-logistic services spread so rapidly worldwide which overlook the significant segment of customer satisfaction. Therefore, the prime objective of the current research study is to develop a comprehensive framework for e-logistics customer satisfaction. Various studies highlighted the area of e- logistic customer satisfaction, however, in a rare case, literature formally documented the problem of e-logistic customer satisfaction. Hence, less attention has been paid to the aspect of customer satisfaction in e-logistic. To address this gap, four hypotheses are proposed concerning the relationship of low distribution charges (LDC), low transit time (LTT), effective payment method (EPM), information technology (IT) and e-logistic customer satisfaction. An e-mail survey was preferred, and questionnaires were distributed by using simple random sampling technique. The three hundred (300) questionnaires were distributed among the e-logistic users. The results of the current study found that low distribution charges, low transit time, effective payment method and information technology had a positive significant relationship with e-logistic customer satisfaction. Furthermore, information technology found main contributory element between effective payment method and e-logistic customer satisfaction. This study is contributing to the body of knowledge by developing a comprehensive framework to solve various e-logistic problems. Hence, the current study is helpful for e-logistic companies to mitigate e-logistic customer satisfaction problems.

Cell load variation is considered a significant shortcoming in scheduling of cellular manufacturing systems. In this article, a new method is proposed for scheduling dynamic cellular manufacturing systems in the presence of bottleneck and parallel machines. The aim of this method is to control cell load variation during the process of determining the best trading off values between in-house manufacturing and outsourcing. A genetic algorithm (GA) is developed because of the high potential of trapping in the local optima, and results are compared with the results of LINGO® 12.0 software. The Taguchi method (an L_9 orthogonal optimization) is used to estimate parameters of GA in order to solve experiments derived from literature. An in-depth analysis is conducted on the results in consideration of various factors, and control charts are used on machine-load variation. Our findings indicate that the dynamic condition of product demands affects the routing of product parts and may induce machine-load variations that yield to cell-load diversity. An increase in product uncertainty level causes the loading level of each cell to vary, which in turn results in the development of “complex dummy sub-cells”. The effect of the complex sub-cells is measured using another mathematical index. The results showed that the proposed GA can provide solutions with limited cell-load variations.

Job selection and scheduling are among the most important decisions for production planning in today’s manufacturing systems. However, the studies that take into account both problems together are scarce. Given that such problems are strongly NP-hard, this paper presents an approach based on two heuristic algorithms for simultaneous job selection and scheduling. The objective is to select a subset of jobs and schedule them in such a way that the total net profit is maximized. The cost components considered include jobs & apos; processing costs and weighted earliness/tardiness penalties. Two heuristic algorithms; namely scatter search (SS) and simulated annealing (SA), were employed to solve the problem for single machine environments. The algorithms were applied to several examples of different sizes with sequence-dependent setup times. Computational results were compared in terms of quality of solutions and convergence speed. Both algorithms were found to be efficient in solving the problem. While SS could provide solutions with slightly higher quality for large size problems, SA could achieve solutions in a more reasonable computational time.

Web 2.0 has changed the way consumers access information. This study aims to investigate the relationship between social media (Watsons’ Facebook page) content and consumers repurchase intention. In addition, it determined whether E-WOM and interactivity can act as the mediating variables between the social media content and repurchase decision. The data were collected through online and offline questionnaires. A total of 146 valid questionnaires were obtained and analyzed using Partial Least Square Structural Equation Modeling (PLS-SEM) through the SMART-PLS 3.3.9 software. The findings support the direct effect of social media content on E-WOM, interactivity, and repurchase intention. Moreover, the results confirmed the mediating role of interactivity between social media content and repurchase intention, however, E-WOM does not mediate between social media content and repurchase intention. The present study suggests some managerial implications for beauty brand retailers and provides fundamental strategies related to their social media.

The role of leaders toward the development of entrepreneurship has been fully acknowledged. However, Leaders’ characteristics such as strategic improvisation and entrepreneurial self-efficacy were mainly examined in the private sector. Hence, it is imperative to extend empirical studies to public sector organizations. The present study, therefore, proposed and validated a model linking leaders’ strategic improvisation and entrepreneurial self-efficacy to corporate entrepreneurship in Nigerian higher education institutions (HEIs). Using a structured questionnaire, 220 responses were generated from large HEIs in Kano State, Nigeria. The data of the study was analysed using SmartPLS 3.0 to ascertain both measurement and structural model validity of the model. The results showed that both leaders’ strategic improvisation and entrepreneurial self-efficacy were significantly related to corporate entrepreneurship in HEIs. Implication and limitation of the study; and suggestions for future study are also provided.

The research was developed with main objective of verifying the effect of perceived transaction speed, performance expectancy and social influence on behavioral intention towards mobile payment services of Cambodian users. A research model was developed in which behavioral intention of mobile payment users was influenced directly by perceived transaction speed, performance expectancy and social influence. The effects of perceived transaction speed on performance expectancy and social influence were analyzed in the research. A successful 210 questionnaires were collected from real mobile payment users in Cambodia. It was identified that behavioral intention was significantly and positively influenced by perceived transaction speed, performance expectancy and social influence. However, the effects of perceived transaction speed on performance expectancy and social influence were not statistically significant. Based on these findings, some recommendations to government, commercial banks and private mobile payment providers in Cambodia were proposed.

Improving employee and organizational performance has been the main concern of many organizations for decades and several factors have also been studied as predictors of employee performance in organizations. However, studies that comprehensively measured all the dimensions of employee performance that enhance organizational effectiveness are limited. This paper explored the influence of HRM practices on the employee performance in the Nigerian public sector. Using cross sectional method on 265 participants from local government areas, the findings revealed that HRM practices such as job rotation, job autonomy and career planning had a significant and positive influence on all the three dimensions of employee performance (task, contextual and adaptive performance).

Accounting is part of everyone’s life and affects all stakeholders who are the users of the accounting information. Organizations are created to serve their stakeholders and governments are supposed to govern, regulate and safe guard the interests of these stakeholders. Whilst accounting frequently experiences behavioral and human governance issues, this study explores the level of ethical sensitivity and its relationship with religiosity among final year accounting students in Malaysia. This study addresses the lack and the need to inculcate religiously orientated topics to be embedded and inculcated in the syllabi of bachelor of accounting, because being intrinsically religious makes an individual ethical. A quantitative research method is applied where questionnaires are administered to final year undergraduate accounting students at selected public and private universities in Malaysia. This study utilized Shaub’s ethical sensitivity questionnaire to measure ethical sensitivity and Allport’s Religiosity Orientation Scale to measure religiosity. Students are found to be ethically sensitive and by using Binary Logistic Regression, it is concluded that ethical sensitivity is influenced by intrinsic religiosity but not influenced by social extrinsic religiosity and personal extrinsic religiosity and may give some insights to the prospective employer on the selection criteria of future accountants and auditors, with regards to ethical conduct.
