Two New Grading Options: Scaling and Importance
No full textTwo new tools for adjusting student grades to more accurately reflect the nuances of student performance, to account for misjudgments in the design of assignments, and to account for the effects of “too-easy” or “too-demanding” grading are introduced. These are called scaling and importance. They are defined and their effects are illustrated

Entanglement Distribution and Secret Key Sharing In Optical Networks
No full textCommunicating a quantum state remotely is possible by Remote State Preparation. Sender Alice create a pure state known to her and help the receiver Bob to securely prepare the state remotely instead of sending the physical quantum state. To successfully perform this protocol the sender and the receiver must share Einstein-Podolsky-Rosen (EPR) state and have access to an authenticated classical channel. The sender and the receiver must be sharing an entangled bit for each state the sender wishes to prepare at the receiver’s location. In this paper we introduce a protocol to create and distribute the required entangled pairs between the communicating parities. A trusted source of EPR states will provide the necessary entangled states required to the sender and the receiver. The distributed EPR state will be used between the communicating parties to create secret keys by using remote state preparation protocol. The proposed protocol will provide unconditional security and any attacking attempt will be discovered due to the disturbance in the states
An Enhanced Communication Protocol for Anonymity and Location Privacy in WSN
No full textWireless sensor networks (WSNs) consist of many sensors working as hosts. These sensors can sense a phenomenon and represent it in a form of data. There are many applications for WSNs such as object tracking and monitoring where the objects need protection. Providing an efficient location privacy solution would be challenging to achieve due to the exposed nature of the WSN. The communication protocol needs to provide location privacy measured by anonymity, observability, capture-likelihood and safety period. We extend this work to allow for countermeasures against semi-global and global adversaries. We present a network model that is protected against a sophisticated passive and active attacks using local, semi-global, and global adversaries

If you are the author of this work and desire to provide it open access or wish access removed, please contact the Wahlstrom Library to discuss permission.Objective – The purpose of this study is to evaluate the importance of Mind-Body Medicine in the treatment of cancer as a way to improve outcome and quality of life. Basic Procedures – Databases used were PubMed, Eureka, Science Direct and AMED. The papers chosen were published within the last 30 years. The research was focused on studies showing the use of mind body medicine with cancer treatment and the outcome. Main Findings – Mind-body medicine showed effectiveness in increasing the outcome of cancer patients. Principal Conclusions – The use of Mind-Body medicine during cancer treatment has increased and is being more accepted among the conventional world due to the efficacy that has been shown in improving quality of life, outcome and overall health in cancer patients
Instructional Coaching Evaluation Using a Realist Approach: a Mixed Methods Study
No full textThe necessity to evaluate professional development has become more pressing for districts in a time of increased accountability. A number of empirical studies had shown that it was difficult to measure the effects of professional development, especially its effect on transferring practice and student achievement. The purpose of this study was to evaluate instructional coaching professional development. A realist evaluation approach was used to develop a realist evaluation based framework and to pilot the instruments to address the need as determined by the literature to effectively evaluate instructional coaching. This study was an evaluation and as such a mixed method study, conducted at one comprehensive high school with instructional coaches, Algebra teachers and students as participants. The researcher a teacher pre-and post survey at the beginning and at the end of the school year, a student survey at the end of the school year as well as a coach survey with the teachers at the end of the year,. During the school year teachers and coaches wrote learning log entries on a quarterly basis and at the end of the year the researcher conducted semi structured interviews with all the participating teachers. All data was able to address five levels of professional development evaluation: teachers’ reactions, teachers’ learning, organizational support, teachers’ use of new knowledge and skills, and students’ learning. Teachers perceived that the instructional coaching increased their knowledge about and their use of instructional practices such as the implementation of group work and the provision of more student centered activities to engage students and promote student to student discourse. Teachers perceived their students to demonstrate increased collaboration in groups, more perseverance, and more independence. The knowledge about the asking of higher- level questions that require students to explain their thinking as well as the provision of multiple representations to support visualization of skills and concepts, showed a significant difference between the average pre and post test scores. The instructional coaching professional development also lead to an increased teacher use of consistently asking higher level questions that require students to explain their thinking as indicated by a significant difference between the average pre and post test scores. The purpose of a realist evaluation was to discover what it was about a program that worked for whom and in what circumstances. The results of the study indicated that the context in which the professional development took place and the perceptions of the teachers about the coaches made a difference in how beneficial the teachers perceived the professional development to be. The realist approach to evaluate instructional coaching professional development is an appropriate design to consider due to the contextual nature of coaching. It provided a process approach to causality with the intent to measure what mechanisms lead to what outcomes and why, while constructing the measures according to theory based assumptions about the causal path of professional development
The Mindfulness Revolution
Get PDFMindfulness meditation is in the news and in our culture, a seemingly new “trend” that celebrities and universities alike have embraced. However, as Professor Donna Oropall points out, this “trend” has been part of Eastern and Western cultures for millennia, and it is only now that science is beginning to catch up. She investigates this phenomenon through her own experiences practicing and teaching, encouraging us to rethink our preconceptions about the way we live
Security of Quantum Key Distribution
No full text© ASEE 2015Every day, the world looks on more of security analysis needs that are based on the enormous and sensitive information. This datum is shared by different systems around the world, which are considered at risk of attack at any time. Many scientists and researchers have brought up another cryptographic subject in Quantum Computing that is so-called Quantum Key Distribution (QKD) protocol. The first QKD is BB84 that was presented by Charles Bennett and Gilles Brassard in 1984. After that, several protocols were created sequentially with the same or different mechanism and with some abilities of these protocols to stand against well-known quantum attacks. This paper studies these protocols deeply and compares them to find the strong and weak points in each considered protocols
Simulation of Droplet Impingement on Solid Surface by the Level Set Method and Phase Field Method
No full textThe simulation of multi-phase flow with moving interfaces is important in a wide range of applications, such as ink-jet printing, metal depositions, spray cooling, and biomedical engineering applications. Level Set and Phase Field methods are two well-known techniques for tracking the moving interfaces. Each model has its own strength and weakness. This paper compares the two surface tracking models in the simulation of droplet impingement process. The simulations are carried out by employing the Level Set and Phase Field models in COMSOL. The dynamic impingement processes is presented for a glycerin droplet impacting a non-wetting wax surface. The simulated spreading factor and apex height are compared with experimental results for the two surface tracking models
