How Should China Sets It's Monetary Policy
No full textChina's monetary policy has evolved from obscurity into spotlight due to its torrid economic expansion in recent times, as well as its exchange rate regime that has been under constant scrutiny of its trading partners. While China’s economy is centrally-planned, it is veering more towards a market-based system with goals of stability and growth. With this in mind, this paper is an introspection of China’s monetary policy since the establishment of the People’s Bank of China (PBC) to the present. Additionally, this paper surveys empirical literature on the effectiveness of policy tools undertaken by the PBC. Recommendations are made to Chinese monetary authority on how to navigate the turbulent waves of economic fluctuations with a managed exchange rate, within its borders and beyond
Effect of Microgravity on Nanoparticle-Cellular Interaction
No full textFaculty Research Day 2018: Student Spaceflight Experiments Program Winning ExperimentFaculty Research Day 2018: Undergraduate Student Poster 1st PlaceA cell contains numerous proteins on its surface and in the cytoplasm that carry out a variety of functions. Maleimide – functionalized Graphene quantum dots (m-GQDs) have the ability to attach or “tag” both cell surface and intracellular proteins in the gravitational setting. Such quantum dots have photoluminescent properties, which can be utilized for tagging the cysteine residue on the proteins and hence in the bio-imaging applications of these proteins. This experiment proposes whether m-GQDs will have a stable binding to cellular proteins on Chinese Hamster Ovary (CHO) mammalian cells under the influence of microgravity. If this occurs, it can provide a wide variety of applications for studying the effects of micro gravity on a physiological system in the way proteins behave compared to a gravitational setting. The basic principle of this procedure can be further utilized to study many more cellular processes under the influence of microgravity by simply tracking these “tagged” cellular proteins under a fluorescence microscope

A Computational Approach for Understanding the Interactions between Graphene Oxide and Nucleoside Diphosphate Kinase with Implications for Heart Failure
No full textDuring a heart failure, an increased content and activity of nucleoside diphosphate kinase (NDPK) in the sarcolemmal membrane is responsible for suppressing the formation of the second messenger cyclic adenosine monophosphate (cAMP)—a key component required for calcium ion homeostasis for the proper systolic and diastolic functions. Typically, this increased NDPK content lets the surplus NDPK react with a mutated G protein in the beta-adrenergic signal transduction pathway, thereby inhibiting cAMP synthesis. Thus, it is thus that inhibition of NDPK may cause a substantial increase in adenylate cyclase activity, which in turn may be a potential therapy for end-stage heart failure patients. However, there is little information available about the molecular events at the interface of NDPK and any prospective molecule that may potentially influence its reactive site (His118). Here we report a novel computational approach for understanding the interactions between graphene oxide (GO) and NDPK. Using molecular dynamics, it is found that GO interacts favorably with the His118 residue of NDPK to potentially prevent its binding with adenosine triphosphate (ATP), which otherwise would trigger the phosphorylation of the mutated G protein. Therefore, this will result in an increase in cAMP levels during heart failure.https://doi.org/10.3390/nano802005

An Improved Novel Key Management Protocol for RFID Systems
No full textThe growing demand to organize resourceful ways of identification has made "Radio Frequency Identification (RFID)" technology universal. One of the key problems in RFID is security and privacy. Many RFID authentication protocols have been proposed to preserve security and privacy of the system. Nevertheless, most of these protocols are analyzed, and it is shown that they cannot provide security against some RFID attacks. In this paper, we present a novel cryptographic scheme, "Hacker Proof Authentication Protocol (HPAP)" which has been improved for "Multiple Tags" authentication at a single time process. We simulated the system using Java Application, and it is a time-saving process. Simulation using Java shows our protocol is secure with the fastest updating timestamps
A Decision Support System for Performance Evaluation: A Combined D-ANP & ANN Approach
No full textIn this study, a novel performance evaluation approach combining DEMATEL, ANP and ANN methods is proposed. The influenced weights for the evaluation criteria are calculated by D-ANP and following this the final ranking of the stores is obtained by utilizing historical data in artificial neural networks
The Role of Proactive Behaviors in the Organizational Socialization of K-12 Principals: A Sequential Mixed Methods Design
No full textA new employee being successfully socialized into the organization and their role in particular is associated with overall individual and organizational success. Moreover, newcomer proactivity is a critical component of the organizational socialization process as individual socialization tactics can contribute to increased newcomer learning. The process of principals being effectively socialized into the role is worthy of investigation since there is ample empirical evidence, which supports how essential the principal is in facilitating school improvement. However, the organizational socialization of principals is an underrepresented topic in the literature. This mixed methods study examined the proactive role principals play in facilitating their own organizational socialization. Phase I of the research utilized data collected from two quantitative questionnaires designed to elicit the information seeking behaviors of K-12 principals as well as how they perceived the information they obtained to enhance their overall knowledge base. Phase II of the study used interview data which provided insight into the other proactive behaviors principals utilized as well as how they made sense of their individual socialization experiences. Furthermore, a never before tested four theory framework was employed as the study’s conceptual foundation in order to determine if (The Need to Belong, Uncertainty Reduction Theory, Social Exchange Theory, and Social Identity Theory) serve as an accurate theoretical foundation for the organizational socialization experiences of K-12 principals. Findings showed principals play an active role in their socialization, which is motivated by great amounts of uncertainty and a need to belong. Moreover, they utilize multiple forms of proactive behaviors such as information seeking and inquiry, relationship building, and feedback seeking through engaging in social exchanges in an effort to fashion a positive social identity within the organization
