A wave of psychological forces in second language learning： An Arabic experience at IIUM

Psychological bases of success deal with relatively inner-self factors. The paper presents basic understandings of learning process as well as a model of identifying factors of second language learning success. There are a number of reasons why some students learn Arabic much more quickly than the others. Learner＇s psychological situation is one of the most expected determination factor. Therefore, its nature has to be described, its function needs to be identified and analyzed, especially in term of motivating students to have better performance in learning Arabic as a second language in the context of International Islamic University Malaysia （IIUM）.     

A model for adoption of mobile banking services using classification and regression trees

The analysis and improvements of bank performance is a challenging issue for bank managers. Among various banking services, mobile banking is one of the most risky fields that is prone to customer resistance. Mobile banking is a form of banking transaction carried out via a mobile phone. Mobile banking allows bank customers to check their account balances and perform credit card transaction, as well as provide information on the latest transaction made by customers. This paper summarizes experiences and results of productively using knowledge discovery and data mining techniques in a large detail bank data. Data mining is the process of extracting patterns from data. We review prior literature on mobile payments, analyze the various factors that impact mobile payment services markets, and suggest directions for future research in this risk management field. Our research work demonstrates the effectiveness and efficiency of data mining in analysis of retailing bank performance. We use classification and regression tree learning algorithm for proposing a customer adoption model of mobile banking according to some personal characteristics of customers.     

The roadmap to net-zero emission: Do geopolitical risk and energy transition matter?

Global crises have heightened policy uncertainties and efforts to address global climate change. Limited evidence exists in the literature on geopolitical risk's direct and indirect roles in addressing global emissions. In this study, we examine whether geopolitical risk could impede or facilitate efforts to attain a net-zero emissions target through energy transition using panel data for 42 countries from 1990 to 2020. Various econometric techniques were applied in this study to present robust findings and reliable conclusions. Estimates from the Driscoll-Kraay, Lewbel two-stage least squares and method of moment regression techniques consistently showed that countries' geopolitical risk directly increases emissions (total greenhouse gas, carbon, methane, and nitrous oxide). At the same time, energy transition, measured with renewable energy consumption, mitigates these emissions. In addition, evidence from the partial linear functional-coefficient model technique indicates that renewable energy consumption consistently mitigates emissions when geopolitical is minimal (at a minimum and mean level). However, the role of renewable energy consumption in reducing emissions becomes weaker when geopolitical risk is heightened—thus, when geopolitical risk reaches its maximum level. We recommend that efforts to sustain renewable energy transition and maintain geopolitical stability are vital for achieving net-zero emissions and climate change mitigation.     

Uneven local implementation of federal policy after disaster: Policy conflict and goal ambiguity

As climate change continues to increase both the frequency and intensity of environmental hazards and disasters, the need for a cohesive national mitigation policy grows. As the environmental federalism scholarship indicates, the inherent tension in federal, state, and local policy implementation highlights that despite a national need, environmental quality is a local public good. To complicate matters, there is disagreement about the optimal level of decision-making regarding the adoption and implementation of environmental policy. This study addresses this gap by considering the role of policy ambiguity and conflict in policy implementation. The analysis relies on primary qualitative data collected from open-ended interviews with 22 local government officials in 12 municipalities following Hurricane Harvey. Through the lens of policy ambiguity and conflict, we find confirmatory support for the idea that policies with less ambiguous goals are more likely to be implemented. Furthermore, we find that policy conflict arises when local governments perceive there is little for the community to gain by implementing the federal program. Thus, the level of protection afforded to citizens varies greatly between communities and is influenced heavily by politics. This research supports the Ambiguity-Conflict Model of policy implementation, an oft-cited but rarely tested theoretical framework for assessing the intergovernmental politics of policy implementation. It also demonstrates the barriers to local implementation of federal environmental policy in a nested system of government.     

Examining the nexus between situational factors and job performance through the mediating role of work engagement and self-efficacy

The situational perspectives theory of job performance is a fundamental aspect of organizational and managerial psychology. Consequently, there is growing interest in conducting additional research to assess situational factors and job performance through the theoretical frameworks of social learning and social exchange theories, which are seldom applied in these domains. The data has been collected from 365 employees working in Pakistan Telecommunication Company Limited (PTCL). It was found that supervisor support stimulates job performance. It is also deduced that self-efficacy mediates the relationship while work engagement does not mediate the relationship between supervisor support and job performance. The situational perspectives theory of job performance provides a supportive framework for the development of PTCL employees. This work should be of interest in the area of situational factors and performance improvement. This study is one of the very few studies conducted to empirically assess the influence of situational factor on performance through the mediating role of work engagement and self-efficacy.     

Reanalysis of the Trotter Tibia Quandary and its Continued Effect on Stature Estimation of Past‐Conflict Service Members

Forensic casework from past‐conflicts relies on the corrected historical Trotter data for stature estimation in Fordisc. For roughly 10 years’, stature estimation using this data has produced point estimates for the tibia that are on average 1.25 inches less than the other long bones. This issue was identified after applying the equations derived from Fordisc to the USS Oklahoma commingled assemblage. Reevaluation of Fordisc revealed that a correction factor of 20 mm, instead of 10 mm, was mistakenly applied to the Trotter tibia data. Historical forensic anthropology reports written at the Defense POW/MIA Accounting Agency were utilized to identify that the overcorrection is isolated to Fordisc 3 with an error rate of 5% of known antemortem statures falling outside of the prediction intervals that relied on the tibia. Further evaluation of the Oklahoma sample indicates the 10 mm correction is still producing point estimates less than the other long bones.     

Sociodemographic variations in the linkage between emotion regulation and peer victimization

Sociodemographic variables may have important implications for understanding the role of global and discrete-level emotion regulation ability in the prediction of elementary school children’s peer victimization. We tested this hypothesis in a sample of 109 elementary school children from economically and racially diverse backgrounds. There was a positive relation between sadness regulation and overt victimization for children in early elementary grades, but not for children in later grades. In addition, there was a positive relation between sadness regulation and relational victimization for boys and a negative association between the two variables for girls. Girls were rated higher than boys on global emotion regulation ability. In addition, economically disadvantaged children reported more relational victimization than their more affluent peers. Affluent children also received higher ratings on global emotion regulation as well as sadness regulation. Anger regulation was also positively associated with overt victimization.     

Measuring the impact of public perceptions on child welfare workers

The Public Perceptions of Child Welfare Scale measures how the social environment influences child welfare workers, including their job satisfaction and intent to leave. Psychometric studies have validated the scale for private child welfare workers, but there are no validation studies with public agency staff. This study fills that gap, showing stigma and respect are important constructs that also predict worker intent to leave. This research found an additional construct, blame, which was not present in private worker validation studies. The scale provides an important tool for the field as we continue to build evidence for effective recruitment and retention.
