Ensayos de calefacción por «glorias»
Authors: Laorden J. , Muñoz R.
Published: August 2016

En el presente trabajo se describen los ensayos realizados haciendo circular los humos de una chimenea a través de un suelo hueco para calentarlo. Los humos salen de la chimenea, recorren el suelo de las habitaciones y vuelven a la chimenea para ser expulsados al exterior. Esta circulación indirecta de los humos se hace, bien por tiro natural de los humos o mediante un tiro forzado provocando por un ventilador axial. Los ensayos han demostrado que los humos pueden calentar una superficie de unos 40 metros cuadrados de suelo. Volviendo otra vez al origen, pero hace falta emplear el ventilador para conseguir que no haya revoco de los humos dentro de la habitación en que está el hogar.

Arquitectura y paisaje
Authors: Neutra Richard J.
Published: August 2016

El esfuerzo humano de composición no está, en manera alguna, fuera de la naturaleza. Nada transciende aquí. Por definición, podemos decir que naturaleza es todo aquello en que pensamos, y nada es extranatural, incluso, por supuesto, el cerebro del hombre y cualquiera de sus manifestaciones y productos. Pero hablando comúnmente, hemos convenido que decir, por ejemplo, una estructura colocada por los castores o un nido construido por un pájaro es naturaleza, y su estudio parte del estudio de la naturaleza. Podemos contrastar estas manifestaciones con lo "artificioso" de nuestros edificios y la incomodidad del espectáculo urbano. Aún las más logradas piezas arquitectónicas, tales como un templo griego colocado sobre un promontorio, con el fondo azul del mar Mediterráneo, puede considerarse como un inserto extraño en el paisaje natural. Su impacto es dulcificado y absorbido, a medida que el elemento aumenta la edad; cuando se convierte en una ruina que muestra la pátina y el contacto con la atmósfera. Entonces revierte a la naturaleza, por decirlo así. Cuando los rayos solares rozan su factura humana, o las formas de las nubes cambian dinámicamente detrás de su silueta o componen variadas sombras sobre ella, nos la hacen más atractiva y armonizan mejor con el paisaje, absorbiéndose en él.

Proyecto: Terminal en el aeropuerto internacional de Dulles
Authors: Saarinen Eero , Ammann - , Whitney -
Published: August 2016

Está proyectado para estación terminal de reactores en Washington y se ha pensado con total funcionalismo, añadiendo una nueva dimensión al viajero, y facilitando y economizando las operaciones del tráfico aéreo. Su extraña y poderosa belleza plástica tiene una clásica dignidad, la cual lo hace idóneo para constituirse en "puerta" de acceso internacional a la capital de los Estados Unidos de América. El aeropuerto está situado en Chantilly (Virginia), y dista de la capital de la nación unos 27 kilómetros. El bloque de la estación terminal es único y concentrado, diferenciándose así de lo habitual, en este tipo de edificios, que suelen tener planta desparramada, con alas en forma de dedos que se aproximan a la situación de los aviones. Esta disposición ha sido posible gracias a la adopción de un método completamente revolucionario y móvil de transporte de viajeros desde los andenes y sala de espera hasta los aparatos. Un cuidadoso estudio del tráfico aéreo, ha patentizado que el sistema tradicional de planta en forma de "palma de mano con los dedos abiertos" ocasiona pesados paseos a los pasajeros y valiosas pérdidas de tiempo.

Design and Development of Educational Multimedia
Authors: Arpaci Ibrahim
Published: August 2016

The decision to implement new technologies such as smart glasses, smart phones, and tablets in an educational setting without determining optimal use scenarios is an evident universal problem as the adoption of such mobile platforms becomes widespread. Semi-structured interviews are conducted with two Science and Technology (S & T) and three Information Technology (IT) public school instructors to further investigate this significant problem. The constant comparative method was used to analyze the qualitative data resulting from these interviews. Preliminary results demonstrate the educational use of tablet computers has several advantages, along with a few limitations needing to be addressed. Specifically, one of the main limitations of these new instructional technologies is the lack of interactive content, embodied in the audio, video, and pictorial multimedia. The urgent need to address this limitation has motivated the development of multimedia software to work seamlessly on tablet computers.

The Impact of Mobile Assisted Language Learning (MALL) on Phrasal Verbs of Iranian Intermediate EFL Students
Authors: Shahrokhi Mohsen , Kamyabi Mina
Published: August 2016

This study investigated the impact of Mobile Assisted Language Learning (MALL) on phrasal verbs learning in EFL context. Participants were 40 intermediate Iranian English learners. They were randomly divided into experimental and control groups of 20 each. The instruction of the control group was limited to the class activities but the experimental group received the instruction through Short Messaging Service (SMS) on their smart cellphones and worked with a new phrasal verbs learning application by Cambridge University Press called Phrasal Verbs Machine (PVM). The analysis of the data revealed that MALL instruction was more effective than in class language learning instruction. Results of the study indicate that smart cellphones as a tool for language learning provide a platform for language learners to use the language actively.
A Mixed Methods Examination of Instructor Social Presence in Accelerated Online Courses
Authors: Lowenthal Patrick R.
Published: August 2016

Social Presence theory seeks to explain how people present themselves as being “there” and “real” while using a communication medium. Most studies on social presence focus on how students present themselves and/or are perceived as being “there” and “real” in computer-mediated environments. However, to date, very few studies have focused on how instructors establish and maintain their own social presence in online learning environments. The following study explored the phenomenon of instructor social presence in accelerated online courses. The results suggest that the construct of presence is more complicated than previously thought and that future studies should employ multiple methods to further explore the concept of instructor social presence.

Authors: Kurt Özlem Efiloğlu , Şimşek Esra İşgör
Published: August 2016

Mobile learning has been a very popular topic in recent years as a result of the accelerating use of mobile devices. This learning type that offers education for everyone without any space and time limitation opens the doors for life-long learning. Even though mobile learning, which is employed to support the traditional education and ensure distant education, seems to have many advantages, it also possesses some disadvantages. Therefore, evaluating mobile learning in various dimensions will contribute to the literature through revealing the antecedents of these advantages and disadvantages. In this chapter, Khan's (2005) eight-dimensional e-learning framework is explained with its dimensions and adapted into mobile learning context. Subsequently, Coursera case which is among the MOOCs that are commonly used nowadays as a mobile interface is evaluated with reference to the framework.
Investigating Mobile Assisted English Foreign Language Learning and Teaching in China
Authors: Liu Haixia , Tao Wenhao , Cain William
Published: August 2016

This study aims to investigate how English as a Foreign Language (EFL) teachers and students in China spontaneously use apps for smartphone and tablets to support their informal language learning. It also seeks to determine EFL teachers' perspectives on informal and formal Mobile Assisted Language Learning (MALL). A total of 240 smartphone and/or tablet users (186 students and 54 EFL teachers) from four colleges in Guangdong China participated in the survey. Twenty-eight teachers selected from the survey participants were interviewed afterwards. Analysis of the survey data showed that all participants were using apps to learn foreign languages informally. Survey data analysis also revealed that the most frequently used apps were based on form-focused behaviorist activities rather than learner-centered constructivist activities. A comparison of usage between EFL teachers and students revealed no significant difference in their choice of apps, yet students expected guidance from EFL teachers in using apps and resources to facilitate language learning. Finally, while the survey data indicated EFL teachers had positive attitudes towards informal MALL, the interviews revealed that many of them held negative sentiments toward MALL in the classroom. We interpret this difference in attitudes as a reflection of the teachers' concerns about learners' self-control and autonomous learning skills, as well as concerns about required teachers' knowledge and perceived changes to teachers' roles. We conclude by discussing the implications of MALL for language teacher education and professional development.

Authors: Woods Kathryn
Published: August 2016

Advances in technology have increased opportunities for students to participate in online courses. While some instructors are beginning their careers teaching only online courses, others are discovering a need to teach sections of courses online after they have enjoyed a long career teaching in a traditional classroom. In either situation, it is important for instructors to recognize that students in online learning environments require the use of different strategies for encouraging engagement and participation in class. In this chapter, the author describes the challenges that students and instructors face specifically in the online learning environment as well as strategies for success, including how to maximize the impact of students' experiences and prior knowledge, using multiple platforms to deliver information, discouraging procrastination, setting clear expectations, encouraging individuality, capitalizing on diversity, and providing and utilizing helpful resources.
The Value of Social Presence in Developing Student Satisfaction and Learning Outcomes in Online Environments
Authors: Marmon Michael
Published: August 2016

As humanity continues into the twenty-first century, online or distance education is emerging as a viable alternative to the learning that is occurring in traditional university-level learning environments. While there is little difference in the quality of learning and information being presented between these two methods, there are distinct differences in the interactions occurring between students and instructors. Specifically, the presence of physical geographic distance creates a feeling of isolation in the minds of the students participating in these online learning environments. This chapter examines the concept of isolation through the lens of Moore's Transactional Distance Theory, which offers an explanation for why such attitudes permeate in this method of instructing students. Moreover, by discussing the history of the medium and the importance of Moore's Transactional Distance Theory, it is possible determine the best practices and procedures for creating a feeling of social presence in online learning environments.
Flipping the Classroom
Authors: Gardner Jamie
Published: August 2016

Adoption of new practice only occurs if the proposed change is perceived as being beneficial and if the challenges associated with implementing the new practice are not overwhelming. The teaching method of flipping the classroom is a newer practice that has received a lot of attention in current literature, where the potential benefits are thoroughly discussed. The challenges associated with flipping the classroom are more obscure in the literature. The purpose of this chapter is to outline challenges associated with flipping the classroom and propose solutions to overcome each of the challenges described. Challenges of implementing a flipped classroom can occur at the institutional or individual level and can be categorized as technological or non-technological. Specific challenges to be discussed include technology delivery challenges at the organizational and individual level, lack of technical support, IT infrastructure challenges, inadequate technical and non-technical training resources for instructors, instructor and student resistance to using non-traditional teaching methods, the inability to assess student comprehension using traditional strategies, increased course preparation time, and lack of student preparation or buy-in.

This study explored graduate students' perceptions of their sense of belonging in online classes, their comfort in participating in online discussions, and their technology skills. Differences in these areas among three different age groups were studied. Data were gathered via an online survey. The results of the data analysis showed that students, regardless of age, felt a sense of belonging and felt comfortable communicating in the online environment. The data also revealed that older students reported feeling more comfortable interacting with their classmates and disagreeing with their classmates while still maintaining trust than their younger counterparts. Such findings inform online educators in designing classes that meet the needs of all learners.
Toward an Open Empowered Learning Model of Pedagogy in Higher Education
Authors: Smyth Robyn , Bossu Carina , Stagg Adrian
Published: August 2016

This chapter will explore some of the emerging trends in higher education worldwide brought by opening up education, including open educational resources (OER), open educational practices (OEP) and massive open online courses (MOOCs). These trends are transforming and challenging the traditional values and structures of universities, including curriculum design, pedagogies, and approaches to recognise and accredit learning assisted by OEP. We will also reflect on ways in which OEP, open ecosystems and the recognition of open learning experiences can further support learners, educators and educational institutions. In doing so, we will revise and re-work a learner centred model (Smyth, 2011) to incorporate some of the current transformation brought by openness. The revised model, called Open Empowered Learning Model, will prompt discussion on alternative ways in which learners, educators and educational institutions could take full advantage of these new trends.

Authors: Good Shari , Clarke Veronika Bohac
Published: August 2016

This chapter analyzes the case of one urban public school district's efforts to provide coherent support for student-centered teaching across all the high schools, through the role of the Learning Leader. The Learning Leader designation replaced the previous Department Head or Curriculum Leader role. The implementation of this change of designation created numerous challenges due to various interpretations of the role. The district's efforts to provide professional development for the Learning Leaders was also caught up in the context of conflicting interpretations of the role of the Learning Leader. This chapter provides an analysis of the implementation of this change, including the use of the Integral Model (Wilber, 2006) to examine the interviews with high school Learning Leaders and principals, and the Professional Development program offered by the district. A number of recommendations are provided for enhancing the role of the Learning Leaders to optimize their work with teachers.
Developing Pedagogical Skills for Teachers
Authors: Ireri Bonface Ngari , Omwenga Elijah I. , Oboko Robert , Wario Ruth
Published: August 2016

Since technology alone without the instructor or teacher cannot deliver learning to learners, the presence of the teacher or instructor is very important. For any meaningful teaching and learning to take place in a class, the teacher must gain learner's attention. Teachers who use learner centered approaches have a strong trust in students, they believe that students want to learn, have great faith in student ability and offer students ownership of class activities. They are able to manage their classroom. This chapter looks at the way attention can be measured and used as a tool to inform teachers in order to enable them manage the classroom and learning activities. There is a significant relationship between rate of response as a measure of attention and use of technology meant for teaching and learning. Teaching and learning technologies draw learners' attention, motivating them and arousing their curiosity to be engaged in learning.
Using Mayer's SOI Approach to Help Learners with ADHD Construct Knowledge
Authors: Salifu Shani
Published: August 2016

The chapter examines Mayer's (1999) Selection, Organization, and Integration components of learning alongside requirements and processes needed to reach conclusions that learning has taken place. Data for the chapter was gathered through the review of appropriate literature, and reviewed to explore the established symptoms of learners diagnosed with ADHD. The review of literature looked at how the identified symptoms interfered with affected learners' classroom behavior, and subsequently with the ways in which they learn. The reviewed literature further explored various beliefs underlying Mayer's (1999) constructivist theory, and how the components outlined by Mayer (1999) can be adapted to facilitate learning among learners with ADHD. The chapter concludes by juxtaposing Mayer's (1999) design strategies with shortcomings that have been found to hinder learning in learners with ADHD. This juxtaposition results in strategies that could ensure that learning becomes possible among learners with ADHD.
On Behavioural Responses and Different Shades of Flaming in Social Media and Computer Mediated Communication
Authors: Verma Ruchi , Nitin Nitin , Srivastava Amit
Published: August 2016

Computer mediated communication has connected the globe in such a way that today the whole world connects with a common thread. It has broken all cultural, social, religious and geographic barriers bringing the world at a zero distance level. Unfortunately, among its innumerable advantages, online communication has developed a darker side to it called flaming. With the freedom that online communication offers, the users have started infiltrating conversation with hostile and offensive exchange of words. Due to the absence of face to face interaction, there are various factors such as anonymity, lack of familiarity, absence of social cordiality and etiquettes that promote flaming. This study takes a look at the social context in which flaming occurs. This paper involves a study conducted on one subject in a confined environment. It focuses on the flaming tendencies and patterns. An effort is done to analyze the factors that affect flaming. The response of the online users on current and controversial issues is recorded. It is generally the sensitive issues that attract flaming. Also non met friends have a tendency to shed their inhibitions and involve blatantly in flaming. Another observation is that the male gender has more inclination towards flaming and involves more in contemptuous comments. The Probit Model is used to analyze the recorded responses and draw the conclusions.

Published: August 2016

Addressing the health problems of the 21st century will require individuals to use a new set of medical and public health resources that extend beyond historic and traditional medical devices and are built on current and smart information technologies. Much of these new medical tools was originally designed by device manufacturers to be used only in clinical settings and by trained healthcare professionals but recently are finding their way into the home nevertheless. Their migration to the home poses many challenges to both caregivers and care recipients. In order to facilitate their migration to the home, it is very important to first understand the domain boundary, its components and their interactions. Little research discusses the context of smart home healthcare and its surrounding entities to date. This paper aims to fill the knowledge gap by developing a framework of smart home healthcare context. To this end, the authors conducted semi-structured interviews with patients and health professionals served for or by home healthcare agencies on the east coast in the United States. They analyzed the content applying thematic approach. The findings revealed four major components of the framework including person, tasks, technologies, and environments. The findings also revealed to define the interactions between these components. The findings have significant implications for smart home designers and manufacturers, and service providers.

A Multi Attribute Selection of Mobile Robot using AHP/M-GRA Technique
Authors: Kumar Surinder , Raj Tilak
Published: August 2016

Today's highly competitive environment and volatile market conditions at national and international level are forcing the manufacturing concerns and its management to adopt the advance automated material handling equipment like mobile robots in a flexible manufacturing system (FMS) to meet the customers' demand regarding quality and variety of product at minimal cost. Selection of a robot is one of the most difficult problems in today's manufacturing environment. The problem has become more challenging due to increasing specifications and complexity of the robot. The main aim of this paper is to develop and implement an integrated methodology based on AHP (Analytical Hierarchy Process) and M-GRA (Modified Grey Relational Analysis) for the selection of a mobile robot for material handling in FMS environment. In this methodology, AHP technique has been used to assign the relative importance between mobile robot selection attributes and M-GRA technique is applied to determine mobile robot selection utility index. The proposed AHP/M – GRA technique is more suitable for the decision making in the presence of vagueness. The methodology is illustrated by means of an example. The ranking and evaluation of this process will provide a good guidance to the decision maker/user to select the appropriate material handling equipment on the basis of attributes.

A classical hallmark of acute inflammation is neutrophil infiltration of tissues, a multistep process that involves sequential cell–cell interactions of circulating leukocytes with IL-1– or TNF-activated microvascular endothelial cells (ECs) and pericytes (PCs) that form the wall of the postcapillary venules. The initial infiltrating cells accumulate perivascularly in close proximity to PCs. IL-17, a proinflammatory cytokine that acts on target cells via a heterodimeric receptor formed by IL-17RA and IL-17RC subunits, also promotes neutrophilic inflammation but its effects on vascular cells are less clear. We report that both cultured human ECs and PCs strongly express IL-17RC and, although neither cell type expresses much IL-17RA, PCs express significantly more than ECs. IL-17, alone or synergistically with TNF, significantly alters inflammatory gene expression in cultured human PCs but not ECs. RNA sequencing analysis identifies many IL-17–induced transcripts in PCs encoding proteins known to stimulate neutrophil-mediated immunity. Conditioned media from IL-17–activated PCs, but not ECs, induce pertussis toxin–sensitive neutrophil polarization, likely mediated by PC-secreted chemokines, and they also stimulate neutrophil production of proinflammatory molecules, including TNF, IL-1α, IL-1β, and IL-8. Furthermore, IL-17–activated PCs, but not ECs, can prolong neutrophil survival by producing G-CSF and GM-CSF, delaying the mitochondrial outer membrane permeabilization and caspase-9 activation. Importantly, neutrophils exhibit enhanced phagocytic capacity after activation by conditioned media from IL-17–treated PCs. We conclude that PCs, not ECs, are the major target of IL-17 within the microvessel wall and that IL-17–activated PCs can modulate neutrophil functions within the perivascular tissue space.

Helper and cytotoxic T cells accomplish focused secretion through the movement of vesicles toward the microtubule organizing center (MTOC) and translocation of the MTOC to the target contact site. In this study, using Jurkat cells and OT-I TCR transgenic primary murine CTLs, we show that the dynein-binding proteins nuclear distribution E homolog 1 (NDE1) and dynactin (as represented by p150Glued) form mutually exclusive complexes with dynein, exhibit nonoverlapping distributions in target-stimulated cells, and mediate different transport events. When Jurkat cells expressing a dominant negative form of NDE1 (NDE1–enhanced GFP fusion) were activated by Staphylococcus enterotoxin E–coated Raji cells, NDE1 and dynein failed to accumulate at the immunological synapse (IS) and MTOC translocation was inhibited. Knockdown of NDE1 in Jurkat cells or primary mouse CTLs also inhibited MTOC translocation and CTL-mediated killing. In contrast to NDE1, knockdown of p150Glued, which depleted the alternative dynein/dynactin complex, resulted in impaired accumulation of CTLA4 and granzyme B–containing intracellular vesicles at the IS, whereas MTOC translocation was not affected. Depletion of p150Glued in CTLs also inhibited CTL-mediated lysis. We conclude that the NDE1/Lissencephaly 1 and dynactin complexes separately mediate two key components of T cell–focused secretion, namely translocation of the MTOC and lytic granules to the IS, respectively.

BCR signaling is a central pathogenetic pathway in chronic lymphocytic leukemia (CLL). Most CLL cells express BCRs of IgM and IgD isotypes, but the contribution of these isotypes to functional responses remains incompletely defined. We therefore investigated differences between IgM and IgD signaling in freshly isolated peripheral blood CLL cells and in CLL cells cultured with nurselike cells, a model that mimics the lymph node microenvironment. IgM signaling induced prolonged activation of ERK kinases and promoted CLL cell survival, CCL3 and CCL4 chemokine secretion, and downregulation of BCL6, the transcriptional repressor of CCL3. In contrast, IgD signaling induced activation of the cytoskeletal protein HS1, along with F-actin polymerization, which resulted in rapid receptor internalization and failure to support downstream responses, including CLL cell survival and chemokine secretion. IgM and IgD receptor downmodulation, HS1 and ERK activation, chemokine secretion, and BCL6 downregulation were also observed when CLL cells were cocultured with nurselike cells. The Bruton’s tyrosine kinase inhibitor ibrutinib effectively inhibited both IgM and IgD isotype signaling. In conclusion, through a variety of functional readouts, we demonstrate very distinct outcomes of IgM and IgD isotype activation in CLL cells, providing novel insight into the regulation of BCR signaling in CLL.
The Lord’s Prayer as a paradigm for restorative justice in brokenness
Authors: Du Plessis Amanda
Published: August 2016

The Lord’s Prayer has a collective and an individual sense. In a pastoral context it can lead the individual believer to inner healing, transformation, faith and redemption; with the result of a collective sense of merciful, sacrificing, restorative justice that forms a paradigm for restorative justice in a broken society. Ultimately the Lord’s Prayer ripples outwards from the supplicant’s own needs to the fulfilment of the love commandment towards God and other people. With the use of the Lord’s Prayer in the pastoral guidance process, the counselee’s attention can shift from a problem-focused attitude to a life of justice, peace and joy. The research question under investigation asks if the Lord’s Prayer can really form a paradigm for restorative justice within a situation of brokenness when it forms part of the pastoral guidance process to give structure to the mixture of emotions that the counselee experiences. The pastoral challenge lies in not limiting newly-found healing to the counselling room, but letting it result in a responsible way of life. Two main themes of the Lord’s Prayer are discussed, namely, human beings’ relationship with God, and their dependence on God for life. The main themes are related to the love commandment, which in itself aims to guide the believer to the realisation of a wider responsibility towards society in respect of merciful, sacrificing, restorative justice that heals brokenness.

Objectives: Epilepsy is very common in the Kingdom of Saudi Arabia, occurring in 6.54 out of every 1000 individuals. The current study was conducted to determine the level of public awareness of and attitudes toward epilepsy in the city of Majmaah, Saudi Arabia. Subjects and Methods: This descriptive study was conducted in Majmaah, Saudi Arabia. The study population included respondents derived from preselected public places in the city. Stratified random sampling was used, and the sample size was made up of 706 individuals. A structured questionnaire was used for data collection from respondents after receiving their verbal consent. The data were analyzed using SPSS version 2.0. Ethical approval was obtained from the Ethics Committee of Majmaah University. Results: The results showed that 575 (81.4%) of the respondents had heard or read about epilepsy. Almost 50% of the respondents knew someone who had epilepsy, and 393 (55.7%) had witnessed what they believed to be a seizure. Results showed that 555 (78.6%) respondents believed that epilepsy was neither a contagious disease nor a type of insanity. It was found that 335 (47.5%) stated that epilepsy was a brain disease, and almost one-quarter of the respondents said that the manifestation of an epileptic episode is a convulsion. Regarding attitude, 49% and 47.3% of respondents stated that they would not allow their children to interact with individuals with epilepsy and would object to marrying an individual with epilepsy, respectively. Conclusion: Although knowledge about epilepsy is improving, it is still not adequate. The study showed that the attitude toward epilepsy is poor.
