Le Musée des antiquités nationales et la « fabrique de la nation »
Authors: Multon Hilaire
Published: October 2016

Inauguré par l’empereur Napoléon III le 12 mai 1867, le musée des Antiquités celtiques et gallo-romaines est inséparable d’un environnement marqué par la construction des mythologies nationales au xix e  siècle. En témoignent le musée des antiquités nationales du Danemark, qui fait figure de pionnier en 1807, ou le musée romain-germanique de Mayence en 1852. Le MAN est également le fruit de l’engagement personnel de l’empereur en faveur de l’archéologie, dans une visée mêlant « césarisme » politique et passion intime, mais aussi de la constitution d’une science archéologique. Avec les découvertes de Jacques Boucher de Perthes dans la vallée de la Somme, la naissance de la préhistoire et l’émergence d’une « France antédiluvienne » marquent tout autant les premières années du musée de Saint-Germain. Au même titre que la Commission de la topographie des Gaules, créée en 1858, le régime entend offrir une réponse à la question des origines de la France et contribuer à la continuité du récit national. Instruire les visiteurs, former le citoyen, en même temps que tendre vers l’universel, telles sont les aspirations premières de cette grande institution muséale.
Les catalogues de la collection des ducs de Leuchtenberg : rédaction et diffusion de savoirs muséographiques européens
Authors: Malouvier Émilie
Published: October 2016

Le modèle adopté pour la rédaction et la diffusion des catalogues de cette collection ducale, proposé par l’architecte Leo von Klenze et le conservateur Johann Nepomuk Muxel à Munich, se distingue des modèles muséaux européens alors en vigueur. Entre 1825 et 1851, les travaux de catalogage illustré et la diffusion internationale de ce « musée de papier » adoptent progressivement une organisation scientifique et contribuent à l’écriture de l’histoire de l’art et des musées en reprenant les réflexions muséographiques de Nicolas de Pigage et de Christian von Mechel à Düsseldorf. L’étude de cette « muséographie de papier » permet de comprendre comment la galerie Leuchtenberg est devenue un musée au sens que lui donne le xix e siècle, en la sortant du champ du privé (dans son statut), du confidentiel (dans sa communicabilité) et de l’aléatoire (dans son organisation).

Authors: Suleiman Randa , Byrd Clavon
Published: October 2016

The purpose of this study was to discover and describe the effectiveness of edTPA mentoring and support program designed by the researchers measured by teacher candidates' perceptions. Within that research purpose, a research theory and/or model was constructed to describe a framework for effective preparation and teacher candidates' support program, which might lead to a successful completion/submission of edTPA entry and increase the probability of attaining a state teaching license. The research question was: What are the teacher candidates' perceptions of the edTPA preparation and support procedures designed by the researchers? This research utilized mixed method interactive program evaluation. An online survey collected teacher candidates' perceptions of mentoring and support for edTPA. The survey questions were organized around four constructs: Preparedness, understanding, submission and support from instructor, university supervisors, cooperating teacher, and resources. A comprehensive data analysis was conducted that identified areas of strength and need of the program.
A Professional Development Framework for the Flipped Classroom Model
Authors: Katz Anne , Brown Tricia Muldoon , Kim Jackie Hee Young
Published: October 2016

A major goal of K-12 education is to create a student-centered classroom where educators are teaching to increase critical thinking skills, promote problem-based learning, and differentiate instruction. However, the reality is that many educators are challenged by the difficult task of creating such a learning environment in their classrooms. In this chapter, the authors will introduce a Flipped Classroom Professional Development project, a Title II Part A Higher Education Improving Teacher Quality State Grant initiative. This project centered on two goals. First, the authors sought to teach the flipped classroom model through an integrated literacy and math approach while “mathematizing” read-aloud instruction for primary and elementary grade educators. Secondly, the chapter describes efforts to expand teachers' repertoire of effective instructional, blended technology tools for teaching math and literacy. The authors will conclude with the potential of the Flipped Classroom model in K-5 settings based upon this professional development framework.

Authors: Halsey R. John
Published: October 2016

The primary purpose of this chapter is to present a rationale for reframing the formation of educational leaders1 that is distinctively rural in its purpose, its character, its ontology, and how it might be progressed. Firstly, understandings of rural and rurality are considered, followed by a discussion of sustainability because of its profound importance to there “being future.” Next, selected critical dimensions and challenges associated with reframing the preparation of rural educational leaders are discussed, including data from an Australia-wide survey. A section on privileging the constructs of rural, space, and spatiality, plus contextual intelligence, relational leadership, and extended leadership field placements completes the chapter.
Systematic Support for STEM Pre-Service Teachers
Authors: Rogers Reenay R.H. , Winship Jodie , Sun Yan
Published: October 2016

Developing a strong STEM teacher workforce is essential to improve K-12 (kindergarten to 12th grade) STEM education and to strengthen the STEM talent pipeline in the United States. Based on the successful experience in Project Engage, a grant funded by the U.S. Department of Education, this chapter proposes an authentic and sustainable four-pillar STEM professional development model. Grounded on social constructivist and interactive approaches, this professional development model is intended to cultivate STEM pre-service teachers' ability to provide K-12 students with authentic STEM learning experience as defined in the four types of authenticity (i.e., context authenticity, task authenticity, impact authenticity, and personal/value authenticity) identified by Strobel and his colleagues (Strobel, Wang, Weber, & Dyehouse, 2013).
Teachers' Use of Social Networking Sites for Continuing Professional Development
Authors: Xerri Daniel
Published: October 2016

On the basis of the results of a study conducted amongst secondary school teachers of English in Malta, this chapter explores the use of Social Networking Sites (SNS) for professional development purposes. In the digital era, SNS provide teachers with the opportunity of creating a Personal Learning Network (PLN), which is an increasingly significant way of acquiring new knowledge and enhancing pedagogical skills while also having the capacity of making teachers feel they belong to a Community of Practice (CoP). This chapter shows how despite their regular use of SNS for personal reasons, teachers do not always exploit these sites to achieve professional development. It is argued that training is a necessary means of not only enabling teachers to learn how to use such tools for such a purpose but also of redefining the way they think about the process of acquiring and sharing knowledge and skills in the 21st century.
Technology Tools, Proficiency, and Integration of Physical Education Teacher Educators
Authors: Baert Helena
Published: October 2016

Accredited Physical Education Teacher Education (PETE) programs within the U.S. are bound by the implementation of national standards, which include a standard on the use of technology to meet lesson objectives. It is the responsibility of PETE faculty and program management to include technology within the program and insure that physical education pre-service teachers are well prepared to integrate technology into their teaching. This chapter investigates the perceptions of PETE faculty towards their technology proficiency, their use of technology in their courses, and the approaches PETE programs use to integrate technology and address the preparedness of pre-service teachers. Results show that PETE faculty use technologies such as computer technologies, pedometers, heart rate monitors and digital cameras most often, yet in general, perceive their proficiency and integration levels to be low. Their technology proficiency levels significantly predicted their level of integration. The chapter also includes recommendations for technology integration in PETE.

This included the necessity to build community leadership for sustainable development and the beginning of the poverty reduction process to take place.
Performance-Based Assessment Evaluated by Croatian Preschool Teachers and Students
Authors: Vorkapić Sanja Tatalović , Katić Vesna
Published: October 2016

Performance-based assessment strongly relies on the observation of children's behavior, preschool teachers' objectivity and accuracy, and presents a significant part of documenting children's development. Therefore, the main aim of this chapter is to analyze the PBA-use and its evaluation by Croatian preschool teachers and students from the Faculty of Teacher Education, University of Rijeka. 60 undergraduate students and 64 preschool teachers participated in this empirical research by filling out self-rated questionnaires. As it was expected, students and preschool teachers demonstrated positive attitudes toward PBA and its documentation in general and if it is applied (will be applied) in practice. However, the students' positive attitudes, satisfaction and perceived usefulness of PBA are significantly higher than those of preschool teachers. These last findings definitely imply the need for modifications of the policy of the preschool education system, as well as significant changes that should be done in practice and relevant study programs.

Authors: Fakayode Sayo O. , Snipes Vincent , Kanipes Margaret I. , Mohammed Abdul K. , Wilson Zakiya S.
Published: October 2016

A continued decline in the student enrollment and retention and graduation rates of Underrepresented Minorities (URM) in STEM majors is a potential threat to future sustainability, viability, and competiveness of several STEM degree programs, particularly at Historically Black Colleges and Universities (HBCUs). The development of a broad-based and inclusive strategy to motivate, excite, retain, and graduate highly qualified URM students in STEM disciplines is therefore a national priority and is imperative for HBCUs. This book chapter highlights four major strategies including: 1) the design and implementation of new curriculum initiatives, active learning pedagogy, and other student engaging pedagogies, 2) early involvement of URM students in hands-on and guided inquiry research experiences in STEM majors, 3) establishing collaborations between HBCUs and Community Colleges, and 4) establishing strong collaborations between HBCUs and local K12 school districts to promote a grass root science education to promote a quality pipeline for HBCUs.

Thus, the main aim of this chapter is to provide an in-depth exploration of those social skills that are needed in order for school principals to become more flexible to external and internal requirements and to balance the need for change with stability. Therefore, an attempt is made to investigate the linkages between school leadership, emotional intelligence, political skill, and teachers' job satisfaction, as well as to examine the correlation of emotional and political skills of principals with the job satisfaction of their teachers.
Principal Leadership in Diverse Cultures
Authors: Walker Allan , Qian Haiyan
Published: October 2016

This chapter draws empirical findings from a larger study that compared principals' leadership across three different international cultural contexts (Hong Kong, Singapore and Perth, Australia) and explored the influence of culture on leadership. Data were collected using interviews and structured vignettes from a purposive sample of 21 principals across three different cultures and were analyzed to arrive at a set of site-specific and cross-cultural comparative propositions. One set of these propositions is reported in the chapter. Societal culture was found to act as a filter and mediator to create substantial differences in leadership behaviors relevant to collaboration. The paper suggests re-thinking in the preparation, training, hiring and selection, of principals, all of which – given multi-ethnic, diverse societies – require more culturally aware and sensitive policies and practices.

Identity, Commitment, and Change Agency
Authors: Kochhar-Bryant Carol A.
Published: October 2016

It is becoming almost cliché to assert that doctoral scholars should integrate theory and practice and address critical problems of practice. Less charted territory, however, moves beyond integration of theory and practice to the cultivation of scholars' as committed people who possess a compass of values and vision as they act as catalysts for change in the world of practice. The purpose of this chapter is to explore the kind of cultivation needed to effect the transformation required for doctoral scholars to move beyond translation of theory to practice to the next step of catalyzing change. This chapter explores the intersection of core constructs or strands for creating scholars as change agents – identity, commitment and civic agency. These elements are examined from a theoretical framework, and in context of a case example of a doctoral program that bridges the academy and the community.

Authors: LeCounte John F. , Johnson Detra
Published: October 2016

In this chapter, the authors present the rapid rise of Massive Open Online Courses (MOOCs) derived from a yearning to create and make widely available materials and conditions for participatory learning and creative space dedicated to the open education. Massive Open Online Courses (MOOCs) were developed to provide open, meaning unrestricted, online courses without higher education cost constraints to students. This new technological platform was embraced, developed, and offered by some of the country's leading universities and institutions including Harvard, University of Pennsylvania, Stanford, and Massachusetts Institute of Technology (MIT). Students may collaborate through strategic social media platforms such as LinkedIn, Facebook, and Twitter. Further, according to LeCounte et al. (2014), the social media partnerships have been found to offer competitive advantages in terms of low cost and tremendous visibility to both corporations and institutions of higher learning.
Joint Professional Development of Teacher Candidates and Mentoring Teachers in Using Project-Based Learning for 21st Century Learning Outcomes
Authors: Shambaugh Neal
Published: October 2016

One teaching strategy that engages students and teachers in 21st century learning outcomes is project-based learning (PBL). This chapter documents two years of professional development with PBL involving 72 teacher candidates, 19 public schools, and 41 mentoring teachers who jointly created, taught, and evaluated 43 PBL units. An online teacher education course structured the professional development over the last semester for teacher candidates. The semester-long course used the state's professional development materials to structure the design, teaching, and evaluation of the PBL units. The chapter is organized around four main ideas. (1) PBL is an appropriate over-arching teaching approach for classroom teachers to address 21st century learning outcomes. (2) PBL teaching provides teachers a relevant setting for media and technology use. (3) PBL implementation requires ongoing professional development and mentoring. (4) Professional development and PBL teaching can involve both teacher candidates and their mentoring teachers learning from each other.
Query Frequency based View Selection
Authors: Syed Mohammad Haider , Kumar T.V. Vijay
Published: October 2016

View selection deals with the selection of appropriate sets of views capable of improving the response times for queries while conforming to space constraints. Materializing all views is infeasible, as the number of possible views is exponential with respect to the number of dimensions and, thus, would not fit within the available storage space. Further, optimal view selection is an NP-Complete problem. Thus, the only remaining alternative is to select a subset of views that reduce the query response time and fit within the available space for materialization. The most fundamental greedy view selection algorithm HRUA considers the size parameter for computing the Top-K views for materialization. In each iteration, it computes the benefit, with respect to size, of all non-selected views, and selects the one entailing the highest benefit for materialization. Though these selected views may be beneficial in respect of their size, they may not be capable of answering large numbers of future queries thereby becoming an unnecessary space overhead. Existing query frequency based view selection algorithms, which address this problem, have been compared in this paper. Experimental results show that each of these algorithms, in comparison to HRUA, are able to select fairly good quality views that provide answers to comparatively greater numbers of queries. Materializing these selected views would facilitate the business decision making process.

Authors: Liu Zhi , Cheng Hercy N.H. , Liu Sanya , Sun Jianwen
Published: October 2016

Due to high retention rates, small private online course (SPOC) has become increasingly popular among universities. However, existing analyses of learning behavioral patterns in SPOC remain extremely lacking. This present study conducts an empirical analysis on the behavioral patterns of 12,517 undergraduates engaging in a college's SPOC platform, called StarC. In this study, the authors collected and summarized the learning behaviors generated from these learners during 348 days of observation. They further coded the behaviors and extracted the two-step lag sequences in learning processes of individuals. The frequency analysis and sequential analysis were subsequently adopted to discover the distributions and frequency transition patterns of the two-step behavioral sequence in StarC. Besides, grade similarities and differences were computed and analyzed in terms of behavioral patterns. With these results, the potential and inadequacies of the learning platform are discussed, and some suggestions are offered for future work on the study and development of SPOCs.
Supply Chain Network Design Optimization with Risk-Averse Retailer
Authors: Golpîra Hêriş
Published: October 2016

This paper proposes a model to formulate a supply chain network design (SCND) problem against uncertainty. The objective of the model is to minimize total cost of the network. The model employs risk averseness of retailers to obtain more realistic model regarding uncertain demand. Using Conditional Value at Risk (CVaR) to deal with this uncertainty makes the model to be robust. In this way, data-driven approach is used to avoid any distributional assumptions because realizations of uncertain parameters are the only information obtainable. This approach reformulates the initial uncertain model as a mixed integer linear programming problem. Numerical results show that the proposed model is efficient for robust SCND with respect to retailers risk averseness.

Published: October 2016

In the current business environment firms have started conceding pressure from the government, international agencies and not-for-profit organizations to make their business activities more responsible towards environment as well as society. Their supply chain management has also imbibed environmental and social concern to its reincarnation as Sustainable Supply Chain Management (SSCM). This paper with help of integrative literature review, experience survey and case study method, develops a three dimensional SSCM framework and its performance metric for Indian IT product industry. This framework suggests Supply Chain (SC) actors on X-axis, Management/Economic (M) on Y-axis and Sustainability (S) on Z-axis. The three levels of Y progresses from operational to tactical and then strategic, whereas Z axis levels are innovation, environment and social. The framework identifies sub-dimensions of sustainability and their connectivity with supply chain process. This research also identifies and proposes the Management and Sustainability performance metric for suggested framework. This framework will help IT product companies to (re)design their SC and develop performance measures on identified metrics.
A New Multidimensional Design Method Based on Meta Model Assistance
Authors: Selmoune Nazih , Alimazighi Zaia
Published: October 2016

Data warehouses have become over the last two decades an essential element in the area of economic intelligence. Although the basic concepts related to this technology are now more standardized (multidimensional model, OLAP technology...), the design method issue remains in discussion, since no proposed method does seem attractive enough to be used rigorously in the real case studies. Indeed, most of the 'Data Warehouse projects' simply follow some design guidelines from the most informal methods. In this paper the authors propose an approach based on the use of the sources metadata to provide help in the multidimensional design. Their approach falls into the category of supply-driven methods, and attempts to cover the various stages of the lifecycle of data warehouses design. The proposed method is associated with a MultiDimensional Design Assistance environment (M2DA) to support the automatic and semi-automatic steps, providing the expected forms of assistance, and managing the interaction with the designer.
Towards a New Model for Causal Reasoning in Expert Systems
Authors: Wright M. Keith
Published: October 2016

This paper presents ideas for improved conditional probability assessment and improved expert systems consultations. It cautions that knowledge engineers may sometimes be imprecise when capturing causal information from experts: their elicitation questions may not distinguish between causal and correlational expertise. This paper shows why and how such models cannot support normative inferencing over conditional probabilities as if they were all based on frequencies in the long run. In some cases, these probabilities are instead causal theory-based judgments, and therefore are not traditional conditional probabilities. This paper argues that these should be processed as if they were causal strength probabilities or causal propensity probabilities. This paper reviews the literature on causal and probability judgment, and then presents a probabilistic inferencing model that integrates theory-based causal probabilities with frequency-based conditional probabilities. The paper also proposes guidelines for elicitation questions that knowledge engineers may use to avoid conflating causal theory-based judgment with frequency based judgment.
Can Agile, Lean and ITIL Coexist?
Authors: Smith Aaron W. , Rahman Nayem
Published: October 2016

Information Technology Infrastructure Library (ITIL) is frequently perceived as overly wordy and bureaucratic while Agile and Lean methodologies are often positioned as a rejection of heavy handed process and governance. But IT Service Management, Agile, and Lean are all focused on the same thing: How to get valuable work done quickly and efficiently in the complex world of IT in order to enable a business's competitive edge. Delivering IT solutions at the speed-of-business while maintaining quality, performance and availability of the Live Environment is a constant balancing act among simultaneous constraints. ITIL, Agile and Lean all contain best-practices to define and manage these constraints and the contexts in which they exist. The authors will compare and contrast the core of these methodologies to show how they align with the goal of providing a roadmap for successful implementation and coexistence.

An Efficient Intra-Server and Inter-Server Load Balancing Algorithm for Internet Distributed Systems
Authors: Panda Sanjaya Kumar , Mishra Swati , Das Satyabrata
Published: October 2016

The growing popularity of Internet Distributed System has drawn enormous attention in business and research communities for handling large number of client requests. These requests are managed by a set of servers. However, the requests may not be equally distributed due to their random nature of arrivals. The optimal assignment of the requests to the servers is a well-known NP-hard problem. Therefore, many algorithms have been proposed to address this problem. However, these algorithms suffer from an excessive number of comparisons. In this paper, a Swapping-based Intra- and inter-Server (SIS) load balancing with padding algorithm is proposed for its solution. The algorithm undergoes a three-phase process to balance the loads among the servers. The proposed algorithm is compared with a client-server load balancing algorithm and the performance is measured in terms of the number of load comparisons and load factor. The simulation outcomes show the efficacy of the proposed algorithm.

Authors: Rao Bapuji , Mishra Brojo Kishore
Published: October 2016

This paper introduces a new approach of clustering of text documents based on a set of words using graph mining techniques. The proposed approach clusters (groups) those text documents having searched successfully for the given set of words from a set of given text documents. The document-word relation can be represented as a bi-partite graph. All the clustering of text documents is represented as sub-graphs. Further, the paper proposes an algorithm for clustering of text documents for a given set of words. It is an automated system and requires minimal human interaction for the clustering of text documents. The algorithm has been implemented using C++ programming language and observed satisfactory results.
Design of a Migrating Crawler Based on a Novel URL Scheduling Mechanism using AHP
Authors: Punj Deepika , Dixit Ashutosh
Published: October 2016

In order to manage the vast information available on web, crawler plays a significant role. The working of crawler should be optimized to get maximum and unique information from the World Wide Web. In this paper, architecture of migrating crawler is proposed which is based on URL ordering, URL scheduling and document redundancy elimination mechanism. The proposed ordering technique is based on URL structure, which plays a crucial role in utilizing the web efficiently. Scheduling ensures that URLs should go to optimum agent for downloading. To ensure this, characteristics of both agents and URLs are taken into consideration for scheduling. Duplicate documents are also removed to make the database unique. To reduce matching time, document matching is made on the basis of their Meta information only. The agents of proposed migrating crawler work more efficiently than traditional single crawler by providing ordering and scheduling of URLs.

Authors: Vasudeva Savdeep , Singh Gurdip
Published: October 2016

This study addresses a research gap in mobile banking (M-banking) related to post service usage consumer behavior and aims to discover the impact of electronic core (e-core) service quality dimensions on the perceived value of service in relation to three socio-economic variables i.e. gender, age and income. The study attempts to identify whether the impact of these dimensions vary as per the difference in socio-economic demographics? Further, E-S-QUAL scale representing dimensions of e-core service quality is utilized and data collection is conducted from a survey of 600 mobile banking users of the Punjab State in India. The collected data is then put to test using Multiple Regression Analysis and Cronbach's alpha. Findings of the study reveal that different customers perceive these dimensions differently depending upon their demographics. This study has important implications for academic research related to e-service quality or to any one doing research in the field of M-banking.
User-Friendly Security Patterns for Designing Social Network Websites
Authors: Alemerien Khalid
Published: October 2016

The number of users in Social Networking Sites (SNSs) is increasing exponentially. As a result, several security and privacy problems in SNSs have appeared. Part of these problems is caused by insecure Graphical User Interfaces (GUIs). Therefore, the developers of SNSs should take into account the balance between security and usability aspects during the development process. This paper proposes a set of user-friendly security patterns to help SNS developers to design interactive environments which protect the privacy and security of individuals while being highly user friendly. The authors proposed four patterns and evaluated them against the Facebook interfaces. The authors found that participants accepted the interfaces constructed through the proposed patterns more willingly than the Facebook interfaces.
Quality and Acceptance of Crowdsourced Translation of Web Content
Authors: Persaud Ajax , O'Brien Steven
Published: October 2016

Organizations make extensive use of websites to communicate with people. Often, visitors to their sites speak many different languages and expect that they will be served in their native language. Translation of web content is a major challenge for many organizations because of high costs and frequent changes in the content. Currently, organizations rely on professional translators or machines to translate their content. The challenge is that professional translations is costly and too slow while machine translations do not produce high quality or accurate translations even though they may be faster and less expensive. Crowdsourcing has emerged as a technique with many applications. The purpose of this research is to test whether crowdsourcing can produce equivalent or better quality translations than professional or machine translators. A crowdsourcing study was undertaken and the results indicate that the quality of crowdsourced translations was equivalent to professional translations and far better than machine translations. The research and managerial implications are discussed.

The Kynurenine Pathway is a Double-Edged Sword in Immune-Privileged Sites and in Cancer: Implications for Immunotherapy
Authors: Routy Jean-Pierre , Routy Bertrand , Graziani Gina M. , Mehraj Vikram
Published: October 2016

The term “immune privilege” was originally coined to describe the suppression of inflammatory responses within organs protected by anatomic barriers, ie, the eyes, brain, placenta, and testes. However, cellular and metabolic processes, which orchestrate immune responses, also control inflammation within these sites. Our current understanding of tolerogenic mechanisms has extended the definition of immune privilege to include hair follicles, the colon, and cancer. By catabolizing tryptophan, cells expressing the enzyme indoleamine-2,3-dioxygenase produce kynurenine metabolites, which orchestrate local and systemic responses to control inflammation, thus maintaining immune privilege. This review highlights the double-edged role played by the kynurenine pathway (KP), which establishes and maintains immune-privileged sites while contributing to cancer immune escape. The identification of the underlying molecular drivers of the KP in immune-privileged sites and in cancer is essential for the development of novel therapies to treat autoimmunity and cancer and to improve transplantation outcomes.

We prove the existence of a (in fact many) holomorphic function ƒ in Cd such that, for any a ≠ 0, its translations f ( · + na) are dense in H(Cd).
Application of Modified Couple Stress Theory and Homotopy Perturbation Method in Investigation of Electromechanical Behaviors of Carbon Nanotubes
Authors: Fakhrabadi Mir Masoud Seyyed
Published: October 2016

The paper presents the size-dependant behaviors of the carbon nanotubes under electrostatic actuation using the modified couple stress theory and homotopy perturbation method. Due to the less accuracy of the classical elasticity theorems, the modified couple stress theory is applied in order to capture the size-dependant properties of the carbon nanotubes. Both of the static and dynamic behaviors under static DC and step DC voltages are discussed. The effects of various dimensions and boundary conditions on the deflection and pull-in voltages of the carbon nanotubes are to be investigated in detail via application of the homotopy perturbation method to solve the nonlinear governing equations semi-analytically.
Efficient and Stable Exponential Runge-Kutta Methods for Parabolic Equations
Authors: Zhu Liyong
Published: October 2016

In this paper we develop explicit fast exponential Runge-Kutta methods for the numerical solutions of a class of parabolic equations. By incorporating the linear splitting technique into the explicit exponential Runge-Kutta schemes, we are able to greatly improve the numerical stability. The proposed numerical methods could be fast implemented through use of decompositions of compact spatial difference operators on a regular mesh together with discrete fast Fourier transform techniques. The exponential Runge-Kutta schemes are easy to be adopted in adaptive temporal approximations with variable time step sizes, as well as applied to stiff nonlinearity and boundary conditions of different types. Linear stabilities of the proposed schemes and their comparison with other schemes are presented. We also numerically demonstrate accuracy, stability and robustness of the proposed method through some typical model problems.

In order to overcome the possible singularity associated with the Point Interpolation Method (PIM), the Radial Point Interpolation Method (RPIM) was proposed by G. R. Liu. Radial basis functions (RBF) was used in RPIM as basis functions for interpolation. All these radial basis functions include shape parameters. The choice of these shape parameters has been and stays a problematic theme in RBF approximation and interpolation theory. The object of this study is to contribute to the analysis of how these shape parameters affect the accuracy of the radial PIM. The RPIM is studied based on the global Galerkin weak form performed using two integration technics: classical Gaussian integration and the strain smoothing integration scheme. The numerical performance of this method is tested on their behavior on curve fitting, and on three elastic mechanical problems with regular or irregular nodes distributions. A range of recommended shape parameters is obtained from the analysis of different error indexes and also the condition number of the matrix system. All resulting RPIM methods perform very well in term of numerical computation. The Smoothed Radial Point Interpolation Method (SRPIM) shows a higher accuracy, especially in a situation of distorted node scheme.
Similarity Solution for the Synchronous Grouting of Shield Tunnel Under the Vertical Non-Axisymmetric Displacement Boundary Condition

Published: October 2016

Similarity solution is investigated for the synchronous grouting of shield tunnel under the vertical non-axisymmetric displacement boundary condition in the paper. The synchronous grouting process of shield tunnel was simplified as the cylindrical expansion problem, which was based on the mechanism between the slurry and stratum of the synchronous grouting. The stress harmonic function on the horizontal and vertical ground surfaces is improved. Based on the virtual image technique, stress function solutions and Boussinesq's solution, elastic solution under the vertical non-axisymmetric displacement boundary condition on the vertical surface was proposed for synchronous grouting problems of shield tunnel. In addition, the maximum grouting pressure was also obtained to control the vertical displacement of horizontal ground surface. The validity of the proposed approach was proved by the numerical method. It can be known from the parameter analysis that larger vertical displacement of the horizontal ground surface was induced by smaller tunnel depth, smaller tunnel excavation radius, shorter limb distance, larger expansion pressure and smaller elastic modulus of soils.

Objectives To understand the attitudes and perceptions of ophthalmologists toward an electronic health record (EHR) system, before and after its clinical implementation.

Methods Ophthalmologists at a single large academic ophthalmology department were surveyed longitudinally before and after implementation of a new EHR system. The survey measured ophthalmologists’ attitudes toward implementation of a new EHR. Questions focused on satisfaction, efficiency, and documentation. All attending physicians (between 56 and 61 at various time points) in the University of Michigan Department of Ophthalmology and Visual Sciences were surveyed. We plotted positive responses to survey questions and assessed whether perceptions followed a J-curve with an initial decrease followed by an increase surpassing pre-implementation levels.

Results Survey responses were received from 32 (52%) ophthalmologists pre-implementation, and 28 (46%) at 3 months, 35 (57%) at 7 months, 40 (71%) at 13 months and 39 (67%) at 24 months post-implementation. After EHR implementation respondents were more likely to express concerns about their ability to create high-quality documentation (p<0.01) and the impact of an electronic health record on meaningful patient interaction (p<0.01). Physicians did not report a significant change in the amount of time spent documenting outside of regular clinical work hours (p=0.54) or on their clinic efficiency and workflow (p=0.97). There was no significant change in overall job satisfaction during the study period (p=0.69). We did not observe a J-curve for any of the survey responses analyzed.

Conclusions As ophthalmology practices continue to transition to EHRs, adapting them to their specific culture and needs is important to maintain efficiency and user satisfaction. This study identifies areas of concern to ophthalmologists that may be addressed through education of physicians and customization of software as other practices move forward with EHR implementation.
