Message from MultiCom-2012 workshop chairs

Welcome to the Second International Workshop on Multimedia Communications and Networking held in conjunction with IUCC-2012 during 25 June – 27 June 2012 in Liverpool, UK. MultiCom-2012 is dedicated to address the challenges in the areas of elivering multimedia content using modern communication and networking techniques. The multimedia & networking computing domain emerges from the integration of multimedia content such as audio and video with content distribution technologies. This workshop aims to cover contributions in both design and analysis aspects in the context of multimedia, wired/wireless/heterogeneous networks, and quality evaluation. It also intends to bring together researchers and practitioners from academia and industry to share their latest achievements in this field with others and establish new collaborations for future developments. All papers received are peer reviewed by three members of the Technical Programme Committee. The papers are assessed by their originality, technical quality, presentation and relevance to the theme of the workshop. Based on the criteria set, four papers have been accepted for presentation at the workshop and will appear in the IUCC conference proceedings. We would like to take this opportunity to thank the IUCC-2012 Organizing Committee, the TPC members of MultiCom-2012 and the authors for their s upport, dedicated work and contributions. Finally, we look forward to meeting you at the workshop in Liverpool.

Working adult students' perspectives on persisting in college

The purpose of this study was to describe and explain working adult undergraduate students' perspectives on persistence in college in order to address the applicability of retention theory to a specific group of college students. Retention of college students is a major concern in higher education where persistence rates have continued to decline for the last 16 years and changing student demographics have influenced enrollment patterns. ^ A qualitative research design was used. Data were collected through in-depth semi-structured interviews with nine working adult undergraduate students. The participants were selected to include diversity in age, race/ethnicity, family roles, career/work levels, college majors, and educational histories. ^ Triangulation was performed on data from the interviews, participant data forms, and a research journal. Open and axial coding were used to generate emerging themes. Member checking was used to verify the interpretation of the participants' perspectives. A peer reviewer corroborated the data analysis. Three major themes emerged from the data which explained how the students stayed motivated, engaged in learning, and managed the institutional aspects of college. ^ Five conclusions were drawn from the findings of this study. First, working adult students described their core experience of college as both positive and negative, creating tensions and often conflicts that influenced their persistence. Second, persistence factors associated with working adult students included personal aspects, such as having clear career/life goals, self management skills, and supportive relationships; learning aspects, such as interactive teaching methods, connections to prior learning, and relevance to career/life goals; and institutional aspects, such as customer service orientation of staff, flexibility of policies and procedures, and convenient access to information. Third, current retention theory was applicable to working adult students. However, working adult students described their experience of academic and social integration differently from that of traditional college students found in the literature. Fourth, findings from this study supported the developmental components of the Adult Persistence in Learning model (MacKinnon-Slaney, 1994). Finally, the study findings indicated a clearly active role required of the institution in the persistence of working adult students by providing flexibility and accessibility in procedures and services. ^

Revaloracion de la comedia de Pedro Munoz Seca: Un teatro menospreciado

The comedies of Pedro Muñoz Seca (1879-1936) received extraordinary public acclaim for over thirty years, yet critics rejected them. Although several experts have recently begun to study his plays in an objective manner, this author has generally either been underrated or omitted from theater histories. This study identifies the merit, contributions and relevance of Muñoz Seca's works so that the unwarranted void that now exists in Spanish theater annals is justly filled. Historical and biographical backgrounds and a brief sketch of the development of comedy in Spain serve to introduce the literary, political and social contexts in which the author develops the subgenre known as "astracán" and introduces the "fresco" character type. ^ This analysis illustrates Muñoz Seca's verbal comic techniques---the use of regional dialects and individuals' speech peculiarities, double entendres, incongruence, periphrasis, and ingenious plays on words. It also explores the author's profound theatrical sense manifested in inter-textual references and self-reflexivity within the content of his plays. In addition, it identifies the scenic creativity he displays through the use of cinematography, the removal of color from stage decor (or the elimination of scenery altogether), and the original application of music to create comic effect. Furthermore, this study comments the satirical tone projected in Muñoz Seca's characters' idiolect and barbarisms as socio-political conditions worsen. Finally, it brings forth the author's use of parody to criticize his society and to deride other theatrical genres in vogue during his time. ^ While the polarization between Muñoz Seca's popular success and the critics' rejection can be explained by esthetic and ideological prejudices, this dissertation ascertains that the true nature of the author's plays has not been properly identified. The "astracán" is a double parody; however, since it caricaturizes a comic subgenre that is already burlesque, its defining parodic features have been consistently misinterpreted as mere exaggerations and defects. What is more, as its critical content is not recognized, its renewing function goes unnoticed. Muñoz Seca's "astracán" illustrates an era of the Spanish comic stage and paves the way for the theater of the absurd. Its merit and relevance must be recognized. ^

Searching for the Holy Grail of International Education: Feedback from Hospitality Management Study Abroad Participants

This article reports on a study done among hospitality management students who participated in study abroad programs between January 2001 and May 2003. The participants in the study were both incoming students to the US and outgoing students from the US. The study investigates, among other things, why they had decided to study abroad, why they had selected a particular institution, how their home institution compared to the partner institution abroad, and what they perceived to be the benefits and relevance of their international experiences. It was found that respondents were generally very positive about the study abroad experience. Some interesting differences of opinion were found when the perceptions of the incoming students were compared to those of the outgoing students. The results of this study may be of particular interest to hospitality management administrators and faculty who create and administer international exchange programs.

Escrever e avaliar textos argumentativos: saberes docentes em ação

This study has investigated texts written by students from two high school- 3 rd grade classrooms, a public school in Natal- RN, and their teachers in order to reveal the nature and relevance of the knowledge that has oriented the teacher in the process of evaluation of argumentative text, set in the genre, opinion article, produced in the school setting. The corpus analyzed is compound with a total of sixteen texts, four of them corresponding to the production of two teachers (two productions per teacher) and twelve on the production of six students (two productions per student, with three students per class). All material on the production of these subjects was collected throughout the 2008 school year, with special attention for students’ productions, which were collected only after being subjected to teacher evaluation. Working knowledge of text linguistics, discourse analysis, the theory of enunciation and the aesthetics of reception, we proceeded to the analysis of production, which in according to the methodological proposal, it was held in two stages: at first, the student and faculty productions were analyzed, separately, in order to verify what knowledge about the object these subjects revealed to have already assimilated. Secondly, two sets were compared (each teacher's texts with the texts of their students). The intention was to unravel the existence (or not) of a connection between the underlying knowledge to the textual production of these teachers and their knowledge manifested in the evaluative act when the interventions made on the productions of the learner. It was found that there is a close correlation between the knowledge revealed in this action and those evidenced in their written productions, which constitutes a strong argument to validate the thesis that teachers also have been shown little proficient in performing their role as producers and evaluators of texts.

A simulação como método de ensino de habilidades no curso de medicina: relato de uma experiência com punção lombar

The teaching of the lumbar puncture (LP) technique with simulator is not well systematized in the curricula of medical schools. Studies show that training in the simulator provides learning technical skills, acquisition and retention of knowledge, improve self-confidence of the learner and enables the transfer to clinical practice. We intend this study to introduce simulated training in LP in medical course at the Universidade Federal do Rio Grande do Norte evaluating the experience taking into account quantitative aspects (performance on standardized tests) and qualitative (perception of the students regarding the method and the teaching process learning). The study was conducted in two phases. In the first phase practical training in PL was introduced in the 3rd year of medical school. Seventy-seven students were trained in small groups, guided by a checklist developed in the model Objective Structured Assessment of Technical Skill (OSATS), at this moment they knew they were not under performance evaluation. They were also asked whether they had prior chances to make an LP in patients. At the end of the first phase the students evaluated training in the following areas: teaching technique, simulator realism, time available per group, number of participants per group and relevance to medical practice. In the second phase, two years later, 18 students trained in first stage performed a new LP on the mannequin simulator, and its performance was evaluated through the same checklist of training in order to verify the technical retention. In addition, they answered a multiple choice test about practical aspects of the LP technique. Each participant received individual feedback on their performance at the end of their participation in the study. In the first phase of the study we found that only 4% of students had performed a lumbar puncture in patients until the 3rd year. The training of LP technique with simulator mannequin was considered relevant and the teaching methods was thoroughly evaluated. In the second phase, all participants were successful in implementing the lumbar puncture on the mannequin simulator, compliance with the most steps in a reasonable time, suggesting that would be able to perform the procedure in a patient.

Building bridges for future sustainability? Breaching the research-teaching nexus in engineering education

The relationship between research and learning and teaching represents what has been described as amongst the most intellectually tangled, managerially complex and politically contentious issues in mass higher education (Scott, 2005, p 53). Despite this, arguments that in order to achieve high quality scholarly outcomes, university teachers need to adopt an approach to teaching similar to that of research (founded upon academic rigour and evidence), has long been discussed in the literature. However, the practicalities of promoting an empirical and evidence-based approach to teaching in engineering education make dealing with the research / teaching nexus a somewhat challenging proposition. Using a phenomenographic approach, bringing together and applying the findings of a mixed methodological study, the workshop will adopt an activity based, interactive approach to encourage staff to consider the challenges and benefits of adopting an evidence-based approach to learning and teaching through the utilisation of research to inform their own practice. © 2009 Authors.

Martin Heidegger's Mathematical Dialectic: Uncovering the Structure of Modernity

Martin Heidegger is generally regarded as one of the most significant—if also the most controversial—philosophers of the 20th century. Most scholarly engagement with Heidegger’s thought on Modernity approaches his work with a special focus on either his critique of technology, or on his more general critique of subjectivity. This dissertation project attempts to elucidate Martin Heidegger’s diagnosis of modernity, and, by extension, his thought as a whole, from the neglected standpoint of his understanding of mathematics, which he explicitly identifies as the essence of modernity.

Accordingly, our project attempts to work through the development of Modernity, as Heidegger understands it, on the basis of what we call a “mathematical dialectic.“ The basis of our analysis is that Heidegger’s understanding of Modernity, both on its own terms and in the context of his theory of history [Seinsgeschichte], is best understood in terms of the interaction between two essential, “mathematical” characteristics, namely, self-grounding and homogeneity. This project first investigates the mathematical qualities of these components of Modernity individually, and then attempts to trace the historical and philosophical development of Modernity on the basis of the interaction between these two components—an interaction that is, we argue, itself regulated by the structure of the mathematical, according to Heidegger’s understanding of the term.

The project undertaken here intends not only to serve as an interpretive, scholarly function of elucidating Heidegger’s understanding of Modernity, but also to advance the larger aim of defending the prescience, structural coherence, and relevance of Heidegger’s diagnosis of Modernity as such.

Deconstrucción de los relatos evangélicos de la pasión. Sobre el arraigo de la ficción en la Historia de las religiones

Las más elementales exigencias de rigor crítico e independencia siguen a menudo sin cumplirse hoy en día en la reconstrucción histórica de la figura del judío Yeshua ben Yosef (Jesús el galileo), en parte porque el carácter inconsistente de las fuentes evangélicas no es tomado en serio. El presente artículo analiza las incongruencias de los relatos de la pasión, muestra en ellos los indicios de un proceso de despolitización, y señala el carácter insostenible de varias afirmaciones clave de muchos historiadores contemporáneos sobre el predicador galileo.

Unraveling networked learning initiatives: an analytic framework

Networked learning happens naturally within the social systems of which we are all part. However, in certain circumstances individuals may want to actively take initiative to initiate interaction with others they are not yet regularly in exchange with. This may be the case when external influences and societal changes require innovation of existing practices. This paper proposes a framework with relevant dimensions providing insight into precipitated characteristics of designed as well as ‘fostered or grown’ networked learning initiatives. Networked learning initiatives are characterized as “goal-directed, interest-, or needs based activities of a group of (at least three) individuals that initiate interaction across the boundaries of their regular social systems”. The proposed framework is based on two existing research traditions, namely 'networked learning' and 'learning networks', comparing, integrating and building upon knowledge from both perspectives. We uncover some interesting differences between definitions, but also similarities in the way they describe what ‘networked’ means and how learning is conceptualized. We think it is productive to combine both research perspectives, since they both study the process of learning in networks extensively, albeit from different points of view, and their combination can provide valuable insights in networked learning initiatives. We uncover important features of networked learning initiatives, characterize actors and connections of which they are comprised and conditions which facilitate and support them. The resulting framework could be used both for analytic purposes and (partly) as a design framework. In this framework it is acknowledged that not all successful networks have the same characteristics: there is no standard ‘constellation’ of people, roles, rules, tools and artefacts, although there are indications that some network structures work better than others. Interactions of individuals can only be designed and fostered till a certain degree: the type of network and its ‘growth’ (e.g. in terms of the quantity of people involved, or the quality and relevance of co-created concepts, ideas, artefacts and solutions to its ‘inhabitants’) is in the hand of the people involved. Therefore, the framework consists of dimensions on a sliding scale. It introduces a structured and analytic way to look at the precipitation of networked learning initiatives: learning networks. Successive research on the application of this framework and feedback from the networked learning community is needed to further validate it’s usability and value to both research as well as practice.

Interventions to Promote Follow-up After Trabeculectomy Surgery in Rural Southern China: A Randomized Clinical Trial.

Importance:

Follow-up after trabeculectomy surgery is important to surgical success, but little is known about the effect of interventions on improving follow-up in low-resource areas.

Objective:

To examine whether text message reminders and free eye medications improve follow-up after trabeculectomy in rural southern China.

Design, Setting, and Participants:

This randomized clinical trial studied 222 consecutive patients undergoing trabeculectomy from October 1, 2014, through November 31, 2015, at 4 rural hospitals in Guangdong and Guangxi Provinces, China. Data from the intention-to-treat population were analyzed.

Interventions:

Patients undergoing trabeculectomy were randomized (1:1) to receive text message reminders 3 days before appointments at 1 and 2 weeks and 1 month after surgery and free topical corticosteroid medication (US$5.30) at each visit or to standard follow-up without reminders or free medication.

Main Outcomes and Measure:

Follow-up at 1 month postoperatively.

Results:

Among 222 eligible patients, 13 (5.9%) refused and 209 (94.1%) were enrolled, with 106 (50.7%) randomized to the intervention group (mean [SD] age, 64.4 [12.7] years; 56 women [52.8%]) and 103 (49.3%) to the control group (mean [SD] age, 63.0 [12.7] years; 53 women [51.5%]). A total of 6 patients (2.9%) were unavailable for follow-up. Attendance at 1 month for the intervention group (59 of 102 [57.8%]) was significantly higher than for the control group (34 of 101 [33.7%]) (unadjusted relative risk [RR], 1.72; 95% CI, 1.13-2.63; P = .01). Factors associated with 1-month attendance in multiple regression models included intervention group membership (RR, 1.65; 95% CI, 1.08-2.53; P = .02) and being told to return for suture removal (RR, 1.80; 95% CI, 1.06-3.06; P = .03). One-month attendance among controls not told about suture removal was 3 of 31 (9.7%), whereas it was 44 of 68 (64.7%) among the intervention group with suture removal (unadjusted RR, 6.69; 95% CI, 2.08-21.6; P = .001).

Conclusions and Relevance:

In this setting, low-cost interventions may significantly improve postoperative follow-up after glaucoma surgery, a potential opportunity for interventions known to improve surgical success.

Konzeption, Implementierung und Anwendung eines automatisierten aerothermodynamischen Vorentwurfsprozesses für Axialturbinen

In dieser Arbeit wird ein Prozess für den frühen aerothermodynamischen Entwurf von Axialturbinen konzipiert und durch Kopplung einzelner Computerprogramme im DLR Göttingen realisiert. Speziell für die Erstauslegung von Geometrien und die Vorhersage von globalen Leistungsdaten beliebiger Axialturbinen wurde ein neues Programm erzeugt. Dessen effiziente Anwendung wird mit einer zu diesem Zweck konzipierten grafischen Entwurfsumgebung ausgeführt. Kennzeichnend für den Vorentwurfsprozess in dieser Arbeit ist die Anwendung von ein- und zweidimensionaler Strömungssimulation sowie der hohe Grad an Verknüpfung der verwendeten Programme sowohl auf prozesstechnischer wie auch auf datentechnischer Ebene. Dabei soll dem sehr frühen Entwurf eine deutlich stärkere Rolle zukommen als bisher üblich und im Gegenzug die Entwurfszeit mit höher auflösenden Vorentwurfsprogrammen reduziert werden. Die Anwendung der einzelnen Programme im Rahmen von Subprozessen wird anhand von exemplarischen Turbinenkonfigurationen in der Arbeit ebenso dargestellt, wie die Validierung des gesamten Entwurfsprozesses anhand der Auslegung einer folgend realisierten und erfolgreich operierenden Axialturbine eines Triebwerkssimulators für Flugzeug-Windkanalmodelle (TPS). Neben der Erleichterung von manueller Entwurfstätigkeit durch grafische Benutzerinteraktion kommt in einzelnen Subprozessen eine automatisierte Mehrziel-Optimierung zum Einsatz.

Utveckling av lojalitetsprogram - individanpassade erbjudanden : Marknadsföring genom CRM-strategier

Den ökade konkurrenssituationen mellan företag är ett resultat på att handeln har globaliserats. Konsumenter är idag mer medvetna om vad företag har att erbjuda, och det är lätt att välja alternativa företag om ett specifikt företag inte lever upp till konsumentens förväntningar. Detta ställer krav på att företag ständigt måste arbeta med och utveckla sina strategier för att skapa konkurrensfördelar. Idag arbetar många företag med lojalitetsprogram som är ett typexempel på en CRM-strategi. CRM-strategier och lojalitetsprogram syftar till att göra konsumenten mer lojal, för att möjliggöra att konsumenten skall välja att göra återupprepande och mer frekventa köp. Lojalitetsprogrammen måste dock uppdateras och förändras, för att ständigt kunna vara konkurrenskraftiga. Företag arbetar därmed för att skapa ett mervärde, det vill säga erbjuda en servicelösning som är utöver vad konsumenten förväntar sig att få från företag. Kundlojalitet kan utvecklas genom att företag skapar långsiktiga relationer med konsumenterna, och en relation mellan parterna kan utvecklas genom att företag lyssnar på konsumenterna, för att få reda på dess behov och önskemål. Forskning indikerar att individanpassade erbjudanden kan bidra till att konsumenterna än mer tenderar att bli lojala, detta eftersom individanpassade erbjudanden är erbjudanden som baseras på konsumentens unika köpbeteende, vilket möjliggör för träffsäkerhet och relevans. Syftet med denna studie är att mäta konsumenters efterfrågan på individanpassade erbjudanden, för att undersöka om konsumenterna faktiskt efterfrågar och kommer ta till sig dessa erbjudanden. Frågeställningarna är; på vilket sätt kan efterfrågan på individanpassade erbjudanden bidra till ett företags konkurrensfördelar samt på vilket sätt skiljer sig efterfrågan på individanpassade erbjudanden beroende på butikernas geografiska placering. Studien är baserad på en kvantitativ surveyundersökning riktad till konsumenter, med en kvalitativ semi-strukturerad intervju för att erhålla viktig information vid utformandet av frågeformuläret. Resultatet för studien visade att konsumenter värdesätter att få individanpassade erbjudanden, och att dessa erbjudanden kan bidra till ett företags konkurrensfördelar eftersom erbjudandena möjliggör att servicekvaliteten kan öka vilket innebär att dessa erbjudanden kan upplevas ha ett mervärde. I denna studie återfanns dock inte några skillnader på efterfrågan av individanpassade erbjudanden beroende på butikernas geografiska placering.

Den goda viljan och framtida lönsamhet : En studie om nedskrivning av goodwill är en ledande indikator på framtida minskad lönsamhet i svenska och finska börsnoterade bolag

Bakgrund: Goodwill är en omdebatterad immateriell tillgångspost. En nedskrivning ska enligt redovisningsstandarden IAS 36 baseras på bolagens framtida ekonomiska utveckling. Därmed kan en nedskrivning vara en indikation på hur bolagets ekonomiska framtid kommer att gestalta sig. Tidigare forskning visar att bolagsledningens subjektiva bedömningar kan leda till att nedskrivningens relevans kan ifrågasättas. Syfte: Enligt IFRS 3 och IAS 36 ska goodwill värderas till det framtida uppskattade värde som tillgången ska generera. Grundtanken med standarderna är att öka tillförlitligheten och relevansen för att bättre återspegla bolagens ekonomi i de finansiella rapporterna. Utifrån grundtanken bör en nedskrivning av goodwill vara en ledande indikator på framtida minskad lönsamhet. Vi avser därmed att undersöka om det finns ett samband mellan nedskrivning av goodwill och minskad framtida lönsamhet i svenska och finska börsnoterade bolag samt om det finns en skillnad mellan länderna när det gäller sambandet. Metod: Uppsatsen är baserad på en kvantitativ metod med en deduktiv ansats där sekundärdata hämtats från databas samt årsredovisningar. Informationen har samlats in för att därefter testas med regressionsanalyser. Slutsats: Studien kan inte styrka att standarden ger en bättre återspegling av bolagens ekonomi i de finansiella rapporterna. Resultatet visar att hanteringen av goodwill kan ske utifrån ett opportunistiskt beteende då nedskrivningen kan vara baserad på en redan realiserad försämring av goodwill istället för att vara baserad på framtida bedömningar. Resultatet antyder att tillsynen inte är harmoniserad inom EU, då det finns en signifikant skillnad mellan Sverige och Finland två år efter nedskrivningen. Studiens resultat kan användas till att ifrågasätta gällande standardens utformning.
