Skype as a Scaffolding Tool for Underprepared Freshmen English Composition StudentsOgden, Conswellor Denise 01 January 2015 (has links)
Nontraditional students enrolled in online courses tend to drop out within their first year because they do not have the basic literacy skills or essential college skills needed for success. They often need the guidance of an online instructor. The purpose of this case study was to explore the perceptions of instructors and students about the effectiveness of Skype as a scaffolding tool for increasing academic achievement for underprepared students in online remedial English composition courses through interactions with their instructor. The conceptual framework included Bruner's cultural-psychological theory of education, Vygotsky's social constructivist theory, and Siemens's connectivism theory. The study was centered on 4 research questions; the first 2 focused on students' and instructors' perceptions of student writing based on student-instructor Skype interactions, and the last 2 concentrated on students' and instructors' perceptions of Skype's effectiveness to scaffold English composition skills to remedial online students. The data sources were 6 student interviews, 2 instructor interviews, and 12 audio recordings of Skype sessions. Data were analyzed for patterns and themes using open coding. The key findings were that students and instructors perceived the Skype interactions created changes in students' writing because of ease of use, indispensableness, rapport, and skill acquisition. This study may affect positive social change by informing online instructors and other personnel of online institutions of higher education about the importance of real-time interactions between students and instructors and providing services for underprepared students using Skype to help enhance their learning of critical writing skills.

Har svenska nyhetsmedier privilegierat Apple Inc? : Undersökning av hur svenska nyhetsmedier publicerar artiklar kopplade till innovationer och företagRosrell, Cecilia Anna, Grunander, Joakim January 2014 (has links)
Sverige anses vara en av världens mest avancerade IT-nationer, där användningen av IT ökar inom både den offentliga och privata sektorn. Företag inom IT branschen expanderar i en starkt föränderlig bransch. En rad olika faktorer har varit grunden till Sveriges position som IT-nation, bland annat en ingenjörs- och innovationstradition över en lång tid, även faktorer som den utbreda användningen av IT i samhället och en snabbhet att implementera nya innovationer. IT-branschen i Sverige utgör 4 % av de sysselsatta i Sverige där omsättning, såväl som antalet anställda, faktiskt ökat även under konjunktursvackor. Syftet med studien är att undersöka om svenska nyhetsmedier i större utsträckning publicerat nyheter om Apple än om deras konkurrenter på smartphone marknaden. For att lättare kunna genomföra studien ska dessa frågeställningar besvaras: Hur har Apple lyckats bygga upp en hajp kring sitt varumärke i Sverige? Har Apple exponerats mer i svenska nyhetsmedier än konkurrenterna på smartphone marknaden? På vilket sätt påverkar svensk nyhetsmedia bilden av Apple? De teorier som används i studien är innovationsteorin, dagordningsteorin samt konsumentbeteendeteorin. Inledningsvis sker en fallstudie där det via sökmotorn på DN och SvD nätupplagor har summerats ihop antalet ordträffar på utvalda ord. Baserat på resultaten av ordanalys utvecklas en semistrukturerad telefonintervju som genomförs med DN. Parallellt sker en semistrukturerad intervju med en anställd på en reklambyrå inriktat mot hur specifikt Apple har gått tillväga för att skapa hajp. Utifrån vår undersökning och analys kom vi fram till att svenska nyhetsmedier inte styrs av bakomliggande faktorer när de offentliggör nyheter om företag. Publiceringar sker baserat på deras uppfattning om hur det allmänintresset ser ut hos läsarna. Apple är väldigt selektiva med att släppa ut information gällande företaget och runt deras produkter, detta resulterar i ett intresse från pressen att först publicera information från Apple, motiverat utifrån ett allmänintresse i samhället.

Previous issue date: 2012-04-23 / Internet Telephony (VoIP) is changing the telecommunication industry. Oftentimes free, VoIP is becoming more and more popular amongst users. Large software companies have entered the market and heavily invest into it. In 2011, for instance, Microsoft bought Skype for 8.5bn USD. This trend increasingly impacts the incumbent telecommunication operators. They see their main source of revenue – classic telephony – under siege and disappear. The thesis at hand develops a most-likely scenario in order to determine how VoIP is evolving further and it predicts, based on a ten-year forecast, the impact it will have on the players in the telecommunication industry.The paper presents a model combining Rogers’ diffusion and Christensen’s innovation research. The model has the goal of explaining the past evolution of VoIP and to isolate the factors that determine the further diffusion of the innovation. Interviews with industry experts serve to assess how the identified factors are evolving.Two propositions are offered. First, VoIP operators are becoming more important in international, corporate, and mobile telephony. End-to-end VoIP (IP2IP) will exhibit strong growth rates and increasingly cannibalize the telephony revenues of the classic operators. Second, fix-net telephony in SMEs and at home will continue to be dominated by the incumbents. Yet, as prices for telephony fall towards zero also they will implement IP2IP in order to save costs. By 2022, up to 90% of the calls will be IP2IP. The author recommends the incumbents and VoIP operators to proactively face the change, to rethink their business strategies, and to even be open for cooperation.

Homage to Everyday PeopleChun, Sang Ja 11 August 2011 (has links)
Influenced by an ever-growing sense of alienation with my homeland, I have been determined to discover through my art practice an ability to challenge conventional notions of home, identity, communication and miscommunication. Exploring these themes, I became increasingly aware of the parallels between everyday life and art practice. By creatively connecting with a diverse amount of local people and their communities, I fulfilled desires to discover a sense of belonging and generated opportunities for others to break through traditional social boundaries and roles.
