Measuring interaction: An empirical comparison of three OLS regression models

The capacity to correctly assess the existence of interaction is a high-value modeling capability among researchers of information systems (IS), especially those focusing on behavioural paradigm studies. Interaction is a notable aspect for the major theoretical frameworks of the IS field, particularly the adoption theories. Allowing for crossover effects in the Theory of Planned Behaviour resulted in improvements in model prediction (Taylor & Todd, 1995b). This study presents the trimmed model, which does not permit crossover effect relations among variables. In complex models, as mentioned by Pedhazur (1997), one variable may affect another variable indirectly through multiple paths. According to him, it stands to reason that indirect effects, through certain paths, may be more meaningful and/or stronger than others. The findings of this quantitative study lead one to conclude that crossover effect models are more capable of showing the interaction among models’ variables, as well as explaining the highest percentage of variation for a single dependent variable, in comparison to the full and trimmed model

A framework to detect cyber-attacks against networked medical devices (Internet of Medical Things):an attack-surface-reduction by design approach

Most medical devices in the healthcare system are not built-in security concepts. Hence, these devices' built-in vulnerabilities prone them to various cyber-attacks when connected to a hospital network or cloud. Attackers can penetrate devices, tamper, and disrupt services in hospitals and clinics, which results in threatening patients' health and life. A specialist can Manage Cyber-attacks risks by reducing the system's attack surface. Attack surface analysis, either as a potential source for exploiting a potential vulnerability by attackers or as a medium to reduce cyber-attacks play a significant role in mitigating risks. Furthermore, it is necessitated to perform attack surface analysis in the design phase. This research proposes a framework that integrates attack surface concepts into the design and development of medical devices. Devices are classified as high-risk, medium-risk, and low-risk. After risk assessment, the employed classification algorithm detects and analyzes the attack surfaces. Accordingly, the relevant adapted security controls will be prompted to hinder the attack. The simulation and evaluation of the framework is the subject of further research.</p

The impact of students' attitude and subjective norm on the behavioural intention to use services of banking system

This study examines the ability and application of the theory of reasoned action TRA in explaining the use of banking system in Yemen.It investigates the impact of two theoretical variables attitude and subjective norms, using a sample consists of university students, on individuals' intention to use banking services. The results of the study revealed a strong predictive power of the theory of reasoned action model to explain university students' behavioural intention to use banking services. Statistically, the finding demonstrated that there are significant and positive relationships between students' attitude, subjective norm as predictor variables on the criterion variable of behavioural intention to use banking services in the context of Yemen. This study adds to the literature by showing non-financial variables such as attitude and subjective norm, which are important in understanding the behavioural intentions toward using banking services. It also provides some theoretical and practical implication. This study is one of the few studies that used theory of reasoned action in the context of Yemen. Furthermore, it has proven its effectiveness in predicting the behavioural intention of students towards using banking services. In addition, the finding will help to design strategies to attract more customers to use the banking system

An investigation of the benefits and barriers of e-business adoption activities in Yemeni SMEs

Yemeni small‐ and medium‐sized enterprises (SMEs) are at the early stages of e‐business adoption and their owners and managers need to be supported to gain an understanding of the benefits that their business can achieve from adopting e‐business. Yemeni SMEs are at the early stages of e‐business adoption. The delay in adopting more advanced e‐business solutions are due to factors including the comparatively low level of technology usage within the organization, lack of qualified staff available to develop, implement and support firms’ websites, and limited financial resources. A lack of computer software and hardware resources appears to have a detrimental effect on e‐business adoption amongst Yemeni SMEs

An Empirical Comparison of Consumer Innovation Adoption Models: Implications for Subsistence Marketplaces

So called “pro-poor” innovations may improve consumer wellbeing in subsistence marketplaces. However, there is little research that integrates the area with the vast literature on innovation adoption. Using a questionnaire where respondents were asked to provide their evaluations about a mobile banking innovation, this research fills this gap by providing empirical evidence of the applicability of existing innovation adoption models in subsistence marketplaces. The study was conducted in Bangladesh among a geographically dispersed sample. The data collected allowed an empirical comparison of models in a subsistence context. The research reveals the most useful models in this context to be the Value Based Adoption Model and the Consumer Acceptance of Technology model. In light of these findings and further examination of the model comparison results the research also shows that consumers in subsistence marketplaces are not just motivated by functionality and economic needs. If organizations cannot enhance the hedonic attributes of a pro-poor innovation, and reduce the internal/external constraints related to adoption of that pro-poor innovation, then adoption intention by consumers will be lower

An examination of the factors influencing Yemeni bank users’ behavioural intention to use internet banking services / Ali Hussein Saleh Zolait

Investigating bank customers’ attitudes, perceptions, norms, behavioural controls and their influence on behaviour can be the right step in understanding the psychological factors affecting individuals to use Internet Banking (IB) in Yemen. This study attempted to provide such an understanding by elaborating Ajzen’s Theory of Planned Behaviour (TPB), a widely applied psychosocial theory in modelling behaviour. In addition, the Diffusion of Innovation (DOI) provides the widely applied concepts of the diffusion of innovation by modelling the attributes of innovation as part of attitudinal belief and the communication channels as part of normative belief. The purpose of this study was to examine the potential prominent factors relating to adopting and using Internet Banking in Yemen as a challenging context representative of developing countries. It also intended to scrutinize the role of Users’ Informational-based Readiness (UIBR) in the presence of other psychological determinants in predicting IB adoption as well as whether or not adopter groups differ from each other in terms of their readiness and the other theoretical factors, and whether or not UIBR is among the prominent predictors which contribute to IB adoption in Yemen. A sample of 369 bank customers was randomly obtained by means of a self administrated survey. A usable response rate of 59.2 % was achieved. SPSS version 14 was used to conduct a series of data analyses of variables assessment for validity and reliability tests and evaluation of regression models in both direct and indirect layers of predictors. The findings of the survey and the empirical bank website evaluation yield several findings. The results of multivariate tests showed that the direct predictors of attitude, Users’ Informational-based Readiness (UIBR), Perceived Behavioural Control (PBC) and Subjective Norm (SN) positively affect behavioural intention to use Internet banking. Cross- validating tests showed that all the direct predictors except SN could be generalized as the prominent predictors of IB. The overall prominent predictors, combined both direct and indirect, obtained in the study’s UR-TPB Model involved Relative Advantage/Compatibility (RAC), UIBR, Attitude, Observability, Technology Facilitating Condition, PBC and Self-efficacy. The model accounted for R2 = 75 percent of the variation of a person’s BI to use IB. The model’s accuracy was judged by the adjusted R2 =.75. The trimmed model explained substantial variance of Intention, Attitude and moderate variance of SN with substantial variance of PBC. In contrast to the rejecter groups, innovator and early adopter groups were represented by those of higher levels of awareness, experience, knowledge and exposure to IB. The respondents significantly viewed IB as advantageous, easy to use and not desirable to be observable. The study showed that IB use in Yemen is still not strong, and this could be due to the newness of IB in general. Banks in Yemen, based on the empirical evaluation of banks’ websites, indicated an acceptable level of informational presence while they were lagging behind at the transaction level. The study makes a significant contribution to theory and academic understanding of the adoption in areas of IS, and specifically IB in the Yemeni context which may guide policy makers and bankers towards the successful diffusion of innovations
