Communication Theory and Interpersonal Interaction. Volume II: Studies in Communication
Authors: Lake Robert
Published: May 2017

These volumes present forty-six articles selected on merit from the proceedings of the Fourth International Conference on Culture and Communication held in 1981 at Temple University. As one would expect from a conference with that broad a mandate, the reader of these volumes is like an air traveller in the desert: we skip from oasis to oasis. As one also expects, some stops are more fruitful than others. But the journey is worth the effort. The quality of the papers is generally high.
Andragogy in Action: Applying Modern Principles of Adult Learning
Authors: Carney Tom
Published: May 2017

After an introduction setting out the current status of andragogy as "the art and science of helping adults learn", the bulk of the book is devoted to accounts of applying andragogy (in: business, industry and government; colleges and universities [the latter being the slowest to exploit the potential of andragogy among the institutions reporting]; the professions; continuing education in the health professions; religious education; elementary and secondary education, and remedial education). A survey of the effectiveness of andragogy in a variety of settings, along with references and an index, concludes the book.

The 1986 Southam Lecture: Culture, Communication "Technology" and Canadian Policy
Authors: Smythe Dallas W.
Published: May 2017

Because life and change is a process of contradictions in everything and person, it is necessary, if we want to have any identity, to be aware of what are the principal contradictions in each set of relationships. In Canada our principal contradiction in relation to our identity is that of the interests of the Canadian people vs. transnational capital. In the global society, the principal contradiction is between people, especially in the Third World, and transnational capital. In both, transnational capital is now the dominant aspect of the contradictions. For Canada the two are linked by the fact that we are simultaneously the most dependent on the United States of all capitalistically advanced countries, and an American neocolony among many Third World neocolonies.
The High Cost of High Tech: The Dark Side of the Chip
Authors: Berg R. D.
Published: May 2017

Non-scholarly, descriptive, comprehensive, factual, and up-to-date, this book destroys conventional wisdom about the social impact of microelectronics and computers, giving a detailed accounting of the second lndustrial Revolution as it occurred in Silicon Valley (Santa Clara County, California), a place often seen as a model for post-mechanical development. Its chapters also deal eloquently with the global impact of the computer and microelectronics industries, focussing on such issues as the computer's effects on the arm's race, individual privacy and freedom, education, employment, two-way communications links such as the telephone and postal services, post-mechanical industrialization and the environment, the Asian assembly labour force, and the trading of information.
Current Research in Film: Audiences, Economics and Law
Authors: Straw William
Published: May 2017

Since the late 1970s. Film Studies as a discipline within North America has come to display many of the signs of paradigmatic coherence. Polemics within the field are increasingly rooted in shared sets of terms and premises, and the theoretical developments produced over the last decade in influential journals such as Screen have trickled down to undergraduate text-books, and laterally into such hitherto isolated enterprises as the writing of corporate histories. For a discipline which suffered for decades from an eclecticism and discontinuity with few parallels elsewhere, this new coherence has brought a sense of community to the field, and an elusive academic respectability. At the same time, a heightened awareness of the political stakes within theoretical debates has. meant that a high level of vigilance exists concerning the acceptability of certain concerns and procedures within academic writing on film.

Poor Communication is Alive and Well: A Study of Annual Report Readability
Authors: Courtis John K.
Published: May 2017

Annual reports are a primary means by which corporations communicate formally with their shareholders, investors, creditors and the general public, and unless this specialized communication medium can be broadly understood, at least some readers will have difficulty arriving at rational investment decisions. Insofar as low levels of annual report comprehension produce resource misallocation behaviour, all of society may be seen to suffer, and not just the individual investor.
The System of Relevances and the Politics of Language in Canadian Public Policy Formation: The Case of Broadcasting
Authors: Fortner Robert S.
Published: May 2017

Alfred Schutz, writing in 1955, argued that successful communication is possible only between persons, social groups, nations, etc., who share a substantially similar system of relevances. The greater the differences, the fewer the chances for successful communication. Complete disparity makes discourse impossible. "To be successful, any communicative process must, therefore, involve a set of common abstractions or standardizations." (Schutz, 1955, 197)

Symbiotic News Coverage of the Grenada Crisis in Canada and the Caribbean
Authors: Surlin Stuart H. , Cuthbert Marlene
Published: May 2017

People in different parts of the world can receive very different impressions of the same event. The symbiotic theory of news suggests that reporters, being products of their own social and psychological environments, will present news information i n a manner consistent with these environments. In this study, symbiotic theory is used to account for differences in Canadian and Caribbean newspaper coverage of the 1983 Grenada crisis.
The Critical Communication Review. Vol. III: Popular Culture and Media Events
Authors: Brown Peter
Published: May 2017

This is a third volume of the The Critical Communications Review edited by Vincent Mosco of Queen's University and Janet Wasko of the California State Polytechnic. The first two volumes dealt with the working class and the media and patterns of communication control. This volume treats popular culture and media events in a variety of ways, but one theme seems dominant: the idea that culture is "contested terrain." Culture is not only what is produced as commodities by elites, but it is "the site of struggles among classes over the production and interpretation o f signs, symbols, and expressions that define themselves and their relationship to one another.

Les pratiques culturelles des Québecois: une autre image de nous-mêmes
Authors: Charland Maurice
Published: May 2017

It states the obvious to assert that Quebec has undergone massive transformations in the last quarter century, but this anthology of essays on cultural practices in Quebec offers the reader insight into the substance of this new Quebec. Fifteen authors, (excluding the editor who provides a conclusion), discuss the state of Quebec's cultural activity in their areas of specialty. The mass media are treated, of course, but so are such other forms as popular and art music, theatre, dance, sports and recreation, and tourism. The editor conceives of the work as contributing to reflection and debate on Quebec cultural development, and in this he succeeds, if only because of the volume of information the work contains.
Political Communication Research: Approaches, Studies, Assessments
Authors: Ichikawa Akira
Published: May 2017

If, as the shopworn Chinese adage has it, a journey of a thousand miles begins with one step, it would appear that political communication researchers have a great distance to travel towards uncertain destinations. The 15 articles making up this collection attest to the arguable view that political communication as a field of inquiry is desperately seeking definition. This, in part, is reflected in the editor's admission that the three general categories that provide t h e subtitle, and under which the contributions are subsumed, are less than distinct.

Research in Composition and Rhetoric: A Bibliographic Sourcebook
Authors: Masou Sutherland Christine T.
Published: May 2017

This collection of 16 articles is remarkable for i t s high standard of scholarship and its comprehensiveness. Nearly all possible approaches to composition are represented, from the process to the product school, and from the scientific to the humanistic. The editors have deliberately avoided taking a position of their own; they have simply tried to include all the points of view which are, i n fact, taken by teachers of composition. It is true that anyone coming to this volume with ideas about the nature of the field still uncrystallized will find little inducement to adopt one position rather than another. But in my view this is an advantage. There are quite enough, perhaps too many, books about composition which adopt a polemical stance. This one comes as close to giving an objective, value-free account of the field as it is possible to come.

VCRs in Canada: Usage Patterns and Policy Implications
Authors: Einsiedel Edna F. , Green Sandra
Published: May 2017

With the entry of the videocassette recorder into the home entertainment market in 1975, the new distribution system has become the conduit to what has been perceived by some as entertainment bounty and diversity, and by others as yet another tool for cultural onslaught. The proliferation of this technology which has shifted controls to the user rather than the sender has in fact led one researcher to describe the situation as "cultural imperialism by invitation" (Ogan. 1985).
Making It: The Business of Film and Television Production in Canada
Authors: Gerace Mary
Published: May 2017

The reading of the recent book, Making It: The Business of Film and Television Production in Canada, produced a vivid recollection of Francois Truffaut's statement about the cinema in La Nuit Americaine. Truffaut, himself, played the filmmaker who was in the process of shooting a movie. During his spare moments, he would read books about Renoir, Hitchcock and Hawks. His nights were filled with a recurring dream of a young boy in Chaplinesque garb stealing stills of the movie, Citizen Kane, from a theatre. The intellectual and subconscious goals were, however, subverted by the exigencies of the film he was shooting. Problems with actors, producers, and investors resulted in constant alteration in the execution of the script. When the leading actor died suddenly, the insurers demanded that the film be completed as expediently as possible. Truffaut's initial desire to make a great film was replaced by the pragmatic acknowledgment that his responsibility was simply to finish it and recoup the investment.
Editor's Column
Authors: Robinson Gertrude J.
Published: May 2017

The present volume features four articles focusing on various aspects of Canadian media regulation. Jean McNulty (Ontario Ministry of Culture and Communications) traces the development of satellite broadcasting from 1969 onward and the ways in which government and business interests have organized his distribution technology to reinforce existing economic and social monoplies of knowledge. Robert Babe (University of Ottawa) relates Canada's differing telephone regulation practices to its particular socio-historical development and problems. Dorothy Zolf (University of Calgary) compares the legal bases of broadcast regulation in Canada and the United States and speculates about the possibilities for dc-regulation. Alan Bartley explores the efficacy of cross-media ownership regulation under the two most recent governments. All writers agree that broadcast regulation is in flux and because it is a political process, the pull of the United States on Canadian affairs remains strong.
Un acercamiento a las representaciones sociales sobre los profesores de educación física. Entre los ecos de una provocación y la respuesta a una infamia
Authors: Toconás Lic. Sergio Gerardo
Published: May 2017

En reuniones de docentes, en diferentes oportunidades, con mayor o menor disimulo, pero de manera cotidiana y casi unánime, se escucha hablar sobre los profesores de educación física. Respecto de su trabajo en las aulas se escucha decir que lo único que saben es tirar la pelota, tocar el silbato, o bien hacer correr a los alumnos alrededor de la pista. Se los critica por el excesivo cuidado o dedicación, su entrenada forma y pulcritud, o contrariamente por la deformación, sobrepeso o desalineo del cuerpo. El objetivo del presente trabajo consiste en analizar desde la teoría de las representaciones sociales, cómo se configuran y cuáles son los elementos que sostienen estos comentarios, comunes por compartidos, cotidianos por reiterados y descalificadores por su contenido. En otras palabras, interesa visibilizar los elementos que conforman estas opiniones que desautorizan el desempeño, la atribución y el crédito social de "los profesores del patio".

Investigations of surface processing of functional ceramics applying ultrashort laser pulses
Authors: Friedrich Maria , Waechter Sebastian , Giesecke Jan , Bliedtner Jens , Bergmann Jean Pierre
Published: May 2017

The development of ultrashort pulse lasers has enabled many new process technologies in the past few years. The nonlinear absorption caused by high peak intensities and the nonthermal ablation are two of the most attractive benefits of pulse durations in the pico- and femtosecond regime, which allow for the processing of a wide variety of materials. Even dielectric, brittle-hard substrates can be processed precisely and gently without cracking or inducing stresses. For this reason, the technology is particularly suited to open up new processing possibilities in the field of functional ceramics. These materials offer many opportunities to set up complex microsystems and multisensor systems. However, the options to structure and shape functional ceramics were limited in the past and had to be solved by elaborate mechanical processes so far. By means of ultrashort pulse laser processing, new applications in the fields of precise shape formation and microstructuring of functional ceramics become accessible. In order to reveal and optimize the processes occurring during surface ablation, investigations with different laser systems have been executed and evaluated by applying various characterization techniques. The results show how the properties of the bulk material and the process parameters such as pulse energy, wavelength, and pulse overlap influence the removal rate as well as the material characteristics, for instance, roughness and morphology. Thereby, the attention is focused on the dependence of the process on the pulse duration. In contrast to the homogenous surface profile that is created during picosecond ablation, the femtosecond process exhibits material modifications in terms of melting patterns. This effect is strongly dependent on the pulse duration, the fluence, and the pulse overlap. It leads to an increase in roughness, which affects the precise material removal. Nevertheless, the investigations also show that the material melting can be utilized to achieve a smoothing effect of the surface if the parameters are well adjusted. The experimental investigations result in optimized process strategies to realize user-defined aims like high ablation rates, high accuracy, or low damage.

The quality of electricity supply, among other issues, deals with continuity indicators as one of the most important factors for the characterization of an adequate service as far as power quality is concerned. In this context, one of the major problems responsible for the unscheduled interruptions is related to the degradation of electrical cables insulation and the well-known water tree effect emerges as an important cause for the deterioration of their insulation layer. If this phenomenon happens, a large loss of insulating properties of dielectric material used to build up such component will occur. In light of these facts, the development of procedures to evaluate, predict, and indicate the operational status of operating cables shows itself highly attractive in order to improve the quality and reliability of energy supply. Focusing on this subject, this paper presents a synthesis of existing methods and a new trend towards the mentioned matter. By using experimental measurements, carried out in medium voltage commercial operating cables in a distribution utility throughout non-invasive approach, applied voltage and insulating leakage currents are obtained to support the analysis. The data are used to obtain degradation indexes to estimate the cables physical operational conditions and the indicators found are further considered in the view of the effectiveness of the strategies for the diagnosis purposes

Air flow prediction and evaluation of ventilation effectiveness with different zonal configurations
Authors: N. Guerfala  , H. Fellouah  , A.Daoud  , N. Galanis
Published: May 2017

This paper proposes a numerical method for the study of ventilation efficiency in buildings. The developed model is validated with the experimental results of Nielsen [5] who tested the isothermal flow in a scaled model of a ventilated room. A zonal method is used to predict airflow patterns in the same ventilated room. The different equations governing the flow in the room were coded in Matlab for different operating conditions, different zonal configurations of the room and different number of cells (control volumes). The efficiency of the ventilation was determined by calculating the number of air changes per hour (ACH) for each cell. The present results show the importance of the inlet air flow rate, the space resolution and the jet inlet dimensions on the determination of air quality.
Islanding detection of synchronous distributed generators
Authors: A. Etxegarai  , I. Zamora  , P. Eguia  , L. Valverde
Published: May 2017

This paper analyses the performance of local passive islanding detection methods for synchronous distributed generators, under different grid and load scenarios. These methods monitor electrical parameters at the interconnection point of a distributed generator and detect island situation whenever these parameters change correspondingly. Lately, islanding detection research has been focused on inverter based systems. But synchronous generators still pose a challenge for study. With this aim, a low voltage distribution network with embedded synchronous generators has been modelled. The performance of frequency and rate-of-change-of-frequency relays have been evaluated, analysing the influence of power mismatch and generator characteristics on the islanding and also avoid false operation.

The  energy  efficiency  improvement is known to start with creating the hi-technology ener-gy  resources  metering  and  accounting  system  which enables  the  financial  mutual  settlements  between  the parties  to  be  improved.  With  data  errors  or  data  loss due to any process failures, the financial consequences may turn out to be severe.

Published: May 2017

This paper utilizes solar radiation data of 25 locations in Oman to investigate economic viability of PV projects considering different market conditions. The study investigates the effects of corporate income tax rate, capital cost allowance, and greenhouse gas reduction credit on the feasibility of a typical 5 MW PV power plant at each of the 25 locations. The results show that despite the generous taxation rate in Oman, taxes represent a big burden on renewable energy projects investors; therefore could hinder investments in this sector when capital cost allowances are not considered in tax calculations.

Published: May 2017

The current increase in the price of fossil fuel and, consequently, of energy, and the decrease in the availability of these resources, led to the enactment of laws, among which the European Directive 31/2010 on Net Zero Energy Buildings (NZEB), with more strict limits on energy needs. So it is grown the interest in constructive solutions and equipments to reduce heat losses and the energy demand for heating, as well as the study to reduce energy needs for cooling and lighting in order to obtain a zero or nearly energy building. This study aims to identify solutions for zero energy building design and investigates some construction technologies and equipments in order to optimize the energy performance and to reduce the environmental impact of residential buildings. A simulation tool was used for the investigation of the feasibility of NZEB applied to a case study.

The selection of biodiesel samples took into account a wide range of ester compounds with different unsaturation characteristics and number of carbon atoms. A model to predict cetane number using artificial neural networks was obtained with better accuracy than 95 %. The best neural network for predict the cetane number was a backpropagationnetwork(11:4:1)using a Conjugate Gradient Descend algorithm for the second training step and showing 96.3 % of correlation for the validation data and a mean absolute error of 1.5.The proposed network is useful for prediction of the cetane number of biodiesel in a wide range of composition but keeping the percent of total unsaturations lower than 80 %. The use of the artificial neural networks in this case let to study and understands the effect of individual fatty acids in the cetane number. Therefore they can be used for improving some biofuel properties related to the combustion process and its efficiency.

Blends of Jatropha Curcas oil and standard diesel fuel were evaluated (without pre-heating). The engine tests for the blends were performed in a Petter single cylinder direct injection diesel engine under steady state conditions at high loads. Engine speeds between 1300-1700 rpm were selected for the engine tests. Torque, power output, specific fuel consumption, in cylinder pressure, ignition delay, rate of heat released and exhaust composition were evaluated. The tested blends between 10-20% of oil shown lower effective torque and power output joint to a higher specific fuel consumption related to the lower heating value of Jatropha oil compared to diesel fuel. Lower pressure peaks and rates or pressure rises were observed when Jatropha blends are used. A decrease in the rate of heat released and shorter ignition delay were observed for the blends. Decreases in HCand CO emissions were observed for blends compared to diesel fuel. Both alternatives assessed shown that the differences observed compared to diesel fuel, can be partially restored with engines regulation. The use of Jatropha oil in order to be a partial or full alternative to the use of diesel fuel for energy production was achieved.

In  this  contribution  a  particular  attention  is  being given  to  the  joint  event  that  bring  together  the  relevant  parties, University  of  Sciences  and  Technology  of  Oran  (USTO-MB),  six Japanese  Universities,  Japan  International  Corporation  Agency (JICA), Japan Science and Technology Agency (JSTA), University of Saida and the URER/MS Renewable Energy Centre of Adrar to develop  a  long-term  vision  and  strategy  to  boost  the  ideas  for  the realisation and the development of the Sahara Solar Breeder (SSB) project.  The  Science  Council  of  Japan  (SCJ)  proposed  the  SSB plan  at  the  G8+5  Academies’  meeting  in  Rome  in  2009,  and appealed  for  international  cooperation  to  solve  the  global  energy and  ecological  issues [1].  The SSB plan  starts from basic  material research on innovative solar Si technology (more than and beyond Siemens processes) and High critical Temperature Superconducting  Cables  (HTcSC)  for  DC  transmission  in  order  to speed up the electric superhighway. The generated electricity from SSB,  made  up  of  a  network  of  Very  Large  Scale-PV  Power Systems  in  Sahara  desert,  will  have  to  be  transferred  to  the  North Africa,  then  Europe,  Africa,  and  ultimately  the  rest  of  the  world, via  HTcSC  that  can  provide,  in  compact  dimension,  firm  capacity for   base   load,   intermediate   and   peaking   power,   effectively complementing  conventional  electricity  sources.  Because  HTcSC are compact and can transmit a large amount of electric power (up to   10   times   as   much   power   as   conventional   electric   power transmission   cable),   it   can   utilize   more   effectively   congested underground  space  where  a  lot  of  piping  and  other  units  already exist.  This  project  will  also  tackle  the  key  challenges  andissues related   to   the   field   of   PV   putting   forward   the   USTO-MB perspective  and  promoting  its  R/D  activities  by  a  collaborative research  plan  between  Japan  and  Algeria.  In  addition  to  the  well-recognized  two  values  of  vast  land  and  sunshine,  the  desert  of Algeria has the third value, sand, for its main component, SiO2.
Optimal Power Sharing of an Inverter-Based Autonomous Microgrid

Published: May 2017

Stability   of   the   autonomous   microgrids   while sharing the power between multiple distributed generation (DG) units is an important task. Conventional droop control is usually used for power sharing between DGs. Power sharing coefficients and controller parameters affect the stability of the microgrid. In this  paper,  to  improve  the  transient  dynamic  response  of  the microgrid,  a  power  derivative-integral  term  is  added  to  the conventional droop control. The design problem is formulated as an  optimization  problem.  The  power  sharing  coefficients  and controller  parameters  are  obtained  using  the  particle  swarm optimization  (PSO)  to  achieve  the  microgrid  stability  based  on power  error  minimization.  Nonlinear  time  domain  simulation is executed  to  investigate  the  proposed  controller  effectiveness  for different   disturbances.   Finally   the   results   show   satisfactory performance  with  efficient  transient  damping  characteristics  of the autonomous microgrid.

Published: May 2017

This paper represents a Fuzzy Logic (FL) based Maximum Power Point Tracking (MPPT) controller for a PV array. The proposed controller is aimed at adjusting the duty cycle of the DC-DC converter switch to track the maximum power of a PV array. MATLAB/Simulink is used to develop and design the PV array system equiped with the proposed MPPT controller. The developed model has been examined under different operating conditions. The performance of the proposed controller has been compared with conventional ones. The results show that the proposed controller is able to track the MPP in a shorter time with less fluctuations. In addition, the robustness of the proposed controller has been confirmed in the rapidly changing irradiation conditions.

Published: May 2017

A PMSM (Permanent Magnet Synchronous Motor) stator inter turn short fault generates the back emf and impedance unbalance element. Those unbalance element cause the torque ripple and the escalating partial heat defect. This paper proposes a dynamic motor model under the internal turn short fault. The proposed model is derived in the positive and negative sequence synchronous reference frame to be easily utilized for the fault detection rule. To validate the proposed scheme, the finite elements method (FEM) simulation with electric circuit is conducted on the PMSM.
Impact of strength of fault current path on the operation of decoupled double synchronous reference frame – phase locked loop
Authors: A. S. Mäkinen  , H. Tuusa
Published: May 2017

This paper studies the performance of decoupled double synchronous reference frame - phase locked loop (DDSRF-PLL) synchronizing method during grid fault. The study is carried out using Matlab/Simulink. The contribution of the paper is to reveal that if the DDSRF-PLL proposed in many papers is used, the control system of network side converter (NSC) may become unstable during a symmetrical grid fault. The instability problem appears only when certain tuning parameters of DDSRF-PLL are used and the fault current path is weak. Thus, the problem may not be easily detected. This paper emphasizes that it is mandatory to use PI-controller with integrator anti windup in the loop filter of DDSRF-PLL. In addition, the impact of angular frequency limitation range on the fault ride through performance is evaluated with comparative simulations.

Published: May 2017

The European EPBD (Energy Performance in Buildings Directive) imposes mandatory inspection of HVAC systems with the aim of reducing building energy consumption and CO2 emission. Even if an inspection methodology was developed by HARMONAC IEE project, only few member states include mandatory inspection in national legislation. The methodology was tested on 400 buildings around Europe, showing some general problems on HVAC control. The main issue concerns HVAC system monitoring: without reliable energy consumption data, it is really difficult to achieve the EPBD main aim, the reduction of energy consumption. In this paper some examples are shown, demonstrating the importance of energy monitoring and correct HVAC control set up.
