Consideraciones sobre el encuentro en Barajas (1963): Una ocasión perdida para las relaciones hispano-marroquíes
Authors: Torres García Ana
Published: December 2013

Algunos estudiosos de la historia de las relaciones hispano-marroquíes han considerado la entrevista en Barajas entre Franco y Hassan II en julio de 1963 un punto de inflexión en la evolución de los contenciosos territoriales entre España y Marruecos. Sin embargo, al mantenerse en secreto el contenido de aquel encuentro, se desconoce exactamente lo tratado por ambos dirigentes, dando pie al surgimiento de diversas interpretaciones y malentendidos que incluso llegan hasta nuestros días. Basado en documentación diplomática inédita, este artículo analiza las circunstancias fundamentales que rodearon aquel episodio para que sea valorado en sus justos términos: la situación política interna marroquí, el desafío que planteaba Argelia y el planteamiento ideológico y estratégico de Hassan II, que quedó claramente plasmado en la propuesta de negociación realizada a España en aquel momento. Tras ello se plantean dos conclusiones fundamentales. La primera es que aquel encuentro de jefes de Estado no fue concluyente al no concretarse ningún acuerdo en materia territorial. La segunda es que el gobierno español, al no ser capaz de aprovechar aquellas circunstancias históricas adoptando una política acorde con los tiempos de la descolonización, perdió la oportunidad de llegar a un acuerdo con Marruecos que le hubiese permitido proteger sus intereses norteafricanos.

Además, utilizamos el indicador de centralidad del análisis de redes sociales para identificar aquellas universidades que muestran un rol más destacado en cada área al tener un mayor número de conexiones directas con el resto de universidades. Finalmente, discutimos la aplicación de esta metodología en un contexto de política científica de cara a la búsqueda de colaboraciones científicas potenciales.
Teaching Mathematics to Electrical Engineering Students by Electrical Engineering Staff in College of Technology in Japan
Authors: Fujimoto Akira , Tokuda Masatoshi , Mori Toru , Sakuma Toshiyuki
Published: December 2013

Electrical engineering staff (reorganized to Electrical and Computer engineering in 2004) has taught electrical engineering students for mathematics classes in Wakayama National College of Technology (WNCT) in Japan from 2007. Effects of the mathematics classes by the electrical engineering staff were evaluated by using the results of the mathematics placement tests. The results of the tests are compared with averages of other National Colleges of Technology in Japan and other divisions of WNCT. As a result, an ability of electrical engineering students for mathematics improved dramatically with increasing the ratio of mathematics classes by the electrical engineering staff. It should seem that these good results were achieved by eagerness and strong motivation of the staff with electrical specialty for improving the ability of their division's students. The reasons for the improvement are discussed and the unique class of mathematics for college of technology is also introduced.
Veillance
Authors: Mann Steve
Published: December 2013

This chapter builds upon the concept of Uberveillance introduced in the seminal research of M. G. Michael and Katina Michael in 2006. It begins with an overview of sousveillance (underwatching) technologies and examines the “We're watching you but you can't watch us” hypocrisy associated with the rise of surveillance (overwatching). Surveillance cameras are often installed in places that have “NO CAMERAS” and “NO CELLPHONES IN STORE, PLEASE!” signage. The author considers the chilling effect of this veillance hypocrisy on LifeGlogging, wearable computing, “Sixth Sense,” AR Glass, and the Digital Eye Glass vision aid. If surveillance gives rise to hypocrisy, then to what does its inverse, sousveillance (wearable cameras, AR Glass, etc.), give rise? The opposite (antonym) of hypocrisy is integrity. How might we resolve the conflict-of-interest that arises in situations where, for example, police surveillance cameras capture the only record of wrongdoing by the police? Is sousveillance the answer or will centralized dataveillance merely turn sousveillance into a corruptible uberveillance authority?

In each case, practical results are presented along with expectations and experiences.
Willingness to Adopt RFID Implants
Authors: Perakslis Christine
Published: December 2013

This chapter presents the results of research designed to investigate differences between and among personality dimensions as defined by Typology Theory using the Myers-Briggs Type Indicator (MBTI). The study took into account levels of willingness toward implanting an RFID (Radio Frequency Identification) chip in the body (uberveillance) for various reasons including the following: to reduce identity theft, as a lifesaving device, for trackability in case of emergency, as a method to increase safety and security, and to speed up the process at airport checkpoints. The study was conducted with students at two colleges in the Northeast of the United States. The author presents a brief literature review, key findings from the study relative to personality dimensions (extroversion vs. introversion dimensions, and sensing vs. intuition dimensions), a discussion on possible implications of the findings when considered against the framework of Rogers’ (1983; 2003) Diffusion of Innovation Theory (DoI), and recommendations for future research. A secondary, resultant finding reveals frequency changes between 2005 and 2010 relative to the willingness of college students to implant an RFID chip in the body. Professionals working in the field of emerging technologies could use these findings to better understand personality dimensions based on MBTI and the possible affect such personality dimensions might have on the process of adoption of such technologies as uberveillance.
We Are the Borg! Human Assimilation into Cellular Society
Authors: Lipschutz Ronnie D. , Hester Rebecca J.
Published: December 2013

As cybersurveillance, datamining, and social networking for security, transparency, and commercial purposes become more ubiquitous, individuals who use and rely on various forms of electronic communications are being absorbed into a new type of cellular society. The eventual end of this project might be a world in which each individual, each cell in the electronic “body politic,” can be monitored, managed, and, if dangerous to the social organism, eliminated. This chapter examines the objectives, desires, and designs associated with such a cellular biopolitics. Are individuals being incorporated into a Borg-like cyber-organism in which they no longer “own” their substance, preferences, desires, and thoughts and in which they are told what they should be doing next?
BookTubers as a Networked Knowledge Community
Authors: Sorensen Karen , Mara Andrew
Published: December 2013

In order to understand the relationship between Networked Knowledge Communities (NKCs) and the Networked Knowledge Society (NKS), the chapter authors conduct a genre analysis of a self-titled New Media genre called BookTube. BookTube is a NKC made up of YouTube content creators who use this particular social media channel to celebrate and discuss books, especially young-adult fiction. By examining how BookTube adheres to discourse community features—shared rules, genres, hierarchies, and values—the contours of this particular NKC become clearer. Stylistic patterns, the roles of authors, and author cultural capital all get negotiated within a discernible and definable set of practices that relate participants to other NKCs and the broader NKS. Furthermore, by relating these discourse features to other latent educational possibilities of the NKS, the authors explore how BookTube might be usefully implemented to model NKC practices in more traditional f2f educational settings.
Technological Mediation in Odissi Dance
Authors: Ghosh Shreelina
Published: December 2013

The practice of teaching in an online composition class might potentially eliminate interpersonal interactivity in a classroom community. Digital mediation can be problematic for functional collaboration in a virtual class. The problem that online instructors might face is one that some traditional Odissi dance teachers also experience. In order to explore the conflict between tradition and mediations with technology, this study focuses on Odissi, an Indian classical dance, and examines how digital technologies of teaching, like CDs, DVD, online videos, and synchronous videos, are transforming the practice and teaching of this traditional dance. A qualitative research of the field of Odissi dance revealed that technologizing the dance might be unavoidable, but to some practitioners it may be disrupting Odissi’s traditional values. This chapter reasserts the position of the teacher in an online pedagogic space and argues that the presence or simulated presence of bodies might be vital in learning and composing collaboratively.
Real-Time and Social Media in Trans-Atlantic Writing/Translation and Translation/Editing Projects
Authors: Hammer Steven , Maylath Bruce
Published: December 2013

This chapter illustrates the ways in which seemingly peripheral contact and communication via social networking are effective means by which members of international and intercultural Networked Knowledge Communities (NKCs) can, in largely informal ways, educate one another in terms of culture, custom, and language use. The authors argue that these increases in communication via new media have resulted in both successful writing/translation collaborations and, in many cases, satisfying long-term personal and professional relationships. To illustrate these claims, the authors draw from written student reflections collected in the last two years in the long-running Trans-Atlantic Project linking writing classes with translation classes. The reflections reveal that, in many ways, the informal, pseudo-immersive communication of new social media and real-time media can be even more effective than traditional pedagogical practices that rely largely on textbook-centered approaches to intercultural education, especially when carried out through a NKC.
Subjective Information Quality in Data Integration
Authors: AbuHalimeh Ahmed , Tudoreanu M. Eduard
Published: December 2013

This chapter focuses on the science of human perception of information quality and describes a subset of Information Quality (IQ) dimensions, which are termed Subjective Information Quality (SIQ). These dimensions typically require a user’s opinion and do not have a clear mathematical technique for finding their value. Note that most dimensions can be measured through multiple techniques, but the SIQ ones are most useful when the user’s experience, opinion, or performance is accounted for. This chapter explores SIQ while considering information obtained from multiple sources, which is a common occurrence when employing visualizations to perform business or intelligence analytics. Thus, the issues addressed here are the assessment of subjective perception of quality of data shown through visual means and principles on how to estimate the subjective quality of combined information sources.
Social Media Tools for Quality Business Information
Authors: Maravilhas Sérgio
Published: December 2013

Information, as a tool to reduce uncertainty and to develop knowledge in organizations, is an important aid in the decision-making process and must be of quality to improve its value. We are living in an information society where organizational and personal life are mediated by information and knowledge, with the help of technologies that gather, disseminate, and deliver that raw material to support our decisions. There are several characteristics that describe the quality of information that will allow the analysis of the value of the information used. In the globalized world we are living in, quality information warrants best results when competing with other organizations. Its value is related to the results that it will allow to be obtained and the dependability on its context. Marketing trends and competitive information is needed for clear decision making about what products to develop, for what customers, at what cost, through which distribution channels, reducing the uncertainty that a new product/service development always brings with it. Social Media tools allow the knowledge of competitor’s moves and the analysis of trends from the communications exchanged in the networks of individual consumers, making it easy for companies to develop solutions according to their clients and prospects desires. Learning how to extract quality information, unbiased, valuable for business, from these social tools is the aim of this work, sharing with the interested parties some ways of using it for their profit and competitive sustainability.

Moving Your College toward Online Programs Including a Quality Matters Implementation Plan
Authors: Allen Deborah A.
Published: December 2013

Moving faculty in a direction toward having online programs/courses at their college can be a daunting task, but another college’s example may assist in preparing for online programs with quality online courses that include a Quality Matters Implementation Plan that will help define how the college will expand faculty knowledge of online education instructional design. In a college’s transition to online education, it is particularly important to “sell” this idea to faculty members. Faculty members at many institutions may be fearful that they will not meet QM standards when going through a course review. Further, faculty members may be fearful of losing the “boundaries” that they currently have teaching in a face-to face setting. Other concerns revolve around budget constraints, preparing the college for online education, keeping consistency in faculty work duties, training faculty, faculty staying current with technology, keeping the same rigor in the online course as a face-to-face course, including an appropriate level of contact with students, and accreditation needs in order to have online education offered at the college. Management and organizational needs include having an administration team that supports faculty in making the change from a face-to-face class to an online class.
ExerLearning®
Authors: Shasek Judy
Published: December 2013

ExerLearning® provides parents, educators and others with a solid background of the direct connection between regular, rhythmic aerobic activity, balance, eye-foot coordination and academic success. We can increase students’ fitness while simultaneously increasing their academic success. Activity breaks have been shown to improve cognitive performance and promote on-task classroom behavior. Today’s exergame and related computer technology can seamlessly deliver activity without over-burdening busy teachers in grades K-12. Activity isn’t optional for humans, and our brain, along with its ability to learn and function at its best, isn’t a separate “thing” perched in our heads. The wiring, the circulation, the connection between mind and body is very real. The brain is made up of one hundred billion neurons that chat with one another by way of hundreds of different chemicals. Physical activity can enhance the availability and delivery of those chemicals. Harnessing technology to that activity is the ExerLearning solution.
From Chaos Towards Sense
Authors: Reiners Torsten , Wood Lincoln C. , Dron Jon
Published: December 2013

Throughout educational settings there are a range of open-focused learning activities along with those that are much more closed and structured. The plethora of opportunities creates a confusing melee of opportunities for teachers as they attempt to create activities that will engage and motivate learners. In this chapter, the authors demonstrate a learner-centric narrative virtual learning space, where the unrestricted exploration is combined with mechanisms to monitor the student and provide indirect guidance through elements in the learning space. The instructional designer defines the scope of the story in which the teacher and learner create narratives (a sequence of actions and milestones to complete a given task), which can be compared, assessed, and awarded with badges and scores. The model is described using an example from logistics, where incoming orders have to be fulfilled by finding the good and delivering it to a given location in a warehouse. Preliminary studies showed that the model is able to engage the learner and create an intrinsic motivation and therewith curiosity to drive the self-paced learning.
Pause Duration of Disfluent Speech
Authors: Teixeira João Paulo , Fernandes Maria Goreti , Costa Rita Alexandra
Published: December 2013

This work has the goal of comparing the pause duration in the disfluent speech and normal speech. Disfluency and normal spontaneous speech was recorded in a context were the subjects had to describe a scene from each other. The pause determination algorithm is presented. The automatic pause determinations allowed the measure of percentage of silence along the record of several minutes of speech. The stuttering scale is used to compare the severity of the subject. As expected, the percentage of speech pauses parameters is rather different in subjects with and without disfluent speech, but it does not seem that it is proportional to the severity of the disfluency.

Authors: Shah Habib , Ghazali Rozaida , Nawi Nazri Mohd , Deris Mustafa Mat , Herawan Tutut
Published: December 2013

The performance of Neural Networks (NN) depends on network structure, activation function and suitable weight values. For finding optimal weight values, freshly, computer scientists show the interest in the study of social insect’s behavior learning algorithms. Chief among these are, Ant Colony Optimzation (ACO), Artificial Bee Colony (ABC) algorithm, Hybrid Ant Bee Colony (HABC) algorithm and Global Artificial Bee Colony Algorithm train Multilayer Perceptron (MLP). This paper investigates the new hybrid technique called Global Artificial Bee Colony-Levenberq-Marquardt (GABC-LM) algorithm. One of the crucial problems with the BP algorithm is that it can sometimes yield the networks with suboptimal weights because of the presence of many local optima in the solution space. To overcome GABC-LM algorithm used in this work to train MLP for the boolean function classification task, the performance of GABC-LM is benchmarked against MLP training with the typical LM, PSO, ABC and GABC. The experimental result shows that GABC-LM performs better than that standard BP, ABC, PSO and GABC for the classification task.

Published: December 2013

Evidently, based on studies which have been conducted over the years, there exist lots more complexity than technical in the development and implementation of information systems in organisations. The complex issues are socio-technical in nature, which require a refresh examination, from social context, if different results are to be achieved. Some of the complexities which are encountered include operational issues, environmental trends, processes flow, communicative scheme, and actors’ relationship. The unpredictable nature of business and rapidly changing user requirements makes it even more difficult to develop and implement systems within budget and timeframe. Other challenges are within the social context, such as politics and culture affiliations. Through the lens of Actor-Network Theory (ANT) understanding of the social context of how information systems are developed and implemented is gained. Although ANT has been employed in many studies, it is of significant important to establishes and clarifies the factors, from the social perspective, which influences the development and implementation of information systems in organisations.

An Improved FTU-Based Matrix Algorithm for Fault Locating in Distribution Network
Authors: Shi Ting Ting , Sun Ming , Wang Lei
Published: December 2013

An improved FTU-based matrix algorithm is presented for faults locating in complex distribution networks with multiple source multiple and faults. Firstly, the paper supposes the only power source and the positive direction according to the structural characteristics of the distribution system, and build the description matrix D which is based on the positive direction and the relevancy between different feeders. Based on the fault currents direction sent from the feeder terminal unit (FTU), we can set up the fault information vector F. Secondly, combined with the description matrix D, by searching the nonzero elements in the fault information vector F , we can establish the fault location vector L according to the fault locating criterion. Finally, by observing the elements in fault location vector L, we can find out the fault area location quickly. This algorithm can solve the problems of feeder terminal fault, circle net fault and multiple source multiple fault, all of which cannot be solved by other algorithm completely. And this method needs not matrix multiply or standardization. It's easy to build the description matrix D, which is very sparse and has good real-time and practicality. The criterion of this algorithm is proved to be effective by simulation in MATLAB environment.

The ultrasonic wave propagation in the isotropic solid is studied. The delay law controlling for electronic scanning of a LUPA transducer is analyzed. The ultrasonic wave propagation in the inspection material can be visualized in the form of displacement cloud images by FEM modeling. Experiments show that the model can efficiently and accurately predict the radiation field of beam focusing, steering and electronic scanning of a linear phased array transducer. By employing the proposed method, parameters can be conveniently changed to study the acoustic field of the ultrasonic beam in the medium. It is very helpful for designing and applying the linear phased array transducer and flaw inspection in NDT field.

Mechanical state has a major impact on the repairing effect of tissue-engineered cartilage. The unusual state could result in the degeneration of artificial and host cartilage. A repaired cartilage defects was simulated by finite element simulation based on fiber-reinforced biphasic model in sliding load condition. The results showed that in the surrounding area of defects Mises stress, compressive strain and pore pressure are affected by the amount of compression and modulus of materials. Inadequate modulus leads to the declining mechanical bearing ability in defected position, while excessive modulus leads to increasing difference between the pressure on the two sides of bonding surface between artificial cartilage and host cartilage. During the repair process, it is suggested to choose the artificial cartilage modulus with both reasonable bearing ability and less stress concentration should be considered, and the intensity of exercise should also decrease to reduce the amount of compression.

The technology of focused beam forming is mainly used for solving some certain problems about high-precision passive positioning in near field. In view of the problem of positioning accuracy, this paper discusses the effects of factors on the width of focused peak and its changes with the factors. The result of study shows the longer arrays length and the higher frequency band of signal and the shorter distance to the target, the narrower width of focused peak, which means the higher the positioning accuracy. The influence of the errors on the positioning accuracy is also simulated and analyzed in this paper. It turned out that, when horizontal linear array is used in the positioning, the horizontal error from the placement of array and parts of array elements no working have little effect on the positioning accuracy for the reason of the horizontal directivity of the array. The vertical errors from the placement of array, from the measurement of depth of the sea and the sound velocity impact the positioning accuracy a bit more. With the analysis of positioning accuracy, it proves that the technology of focused beam forming can realize high-precision positioning in near field. Finally, several suggestions on improving the positioning quality are offered.

An interference image edge detection method for laser interferometer hydrophone based on wavelet packet is investigated. Considering the effect of ocean background noise on the interference image, we propose the use of a class of wavelet packet functions to make decomposition on noisy interference image, and then make reconstruction on approximate parts of the decomposed image. The approximate parts with the wavelet packet decomposition is of more clear image layers comparison to the original image, and the wavelet packet decomposition method can reduce the influence of background noise on the interference image. Taking the wavelet packet decomposition method and other edge detection algorithms for contrast, it is proved that the wavelet packet decomposition method for edge detection algorithm is more effective than the other algorithms.
