For growing organisations that have built their data flow around a monolithic database server, anever-increasing number of applications and an ever-increasing demand for data freshness willeventually push the existing system to its limits, prompting either hardware upgrades or anupdated data architecture. Switching from an approach of full extractions of data at regularintervals to an approach where only changes are extracted, resource consumption couldpotentially be decreased, while simultaneously increasing data freshness. The objective of this thesis is to provide insights into how implementing an event streamingsetup with Apache Kafka connected to SQL Server through the Debezium source connectoraffects resource consumption on the database server. Other studies in related work have oftenbeen focused on steps further downstream in the data pipeline. This thesis can thereforecontribute to an area where more knowledge is needed. Through an empirical study done using two different setups in the same system, traditional dataextraction in batches and extraction through event streaming is measured and compared. The point of measurement is the SQL Server database from which data is extracted. Both memoryutilisation and CPU utilisation is measured, using SQL Server Profiler. Different parameters fortable sizes, volumes of data and intervals between changes are used to simulate differentscenarios. One of the takeaways of the results is that, at the same number of total changes, the size of theindividual transactions has a large impact on the resource consumption caused by eventstreaming. The study shows that an overhead cost is involved with each transaction, and also thatthe regular polling that the source connector performs causes resource consumption even inidleness. The thesis concludes that event streaming can offer reduced resource consumption on thedatabase server. However, when the source table size is small, and the number of changes large,extraction in batches is less resource-intensive.

Museums Connect stands at the intersection of public history and public diplomacy. The program, which has both public history and public diplomacy agendas, is sponsored by the United States Department of State and administered by the American Alliance of Museums. This dissertation examines the competing impulses of transnational public history and public diplomacy made manifest in Museums Connect and its ramifications for public history theory and practice. The project demonstrates both the seeming similarities between public history’s ideas of shared authority, dialogic museum practice, and community engagement and public diplomacy’s “people-to-people” diplomacy, as well as the limits of these similarities. This dissertation also considers the ramifications of these dynamics on museum and public history practice and theory. It is shown that the assumptions of public diplomacy found in Museums Connect inform the program’s structure and operation, while also precluding a truly shared authority between the American museums and their international partners. The appointment of the American museums as “lead” museums and the Department of State’s choice to focus on young people as the target audience for the program foregrounds didactic relationships between the museums and their “communities” for the projects. Through three case studies of Museums Connect projects between the United States and Afghanistan, Morocco, and South Africa, this dissertation challenges the seminal theoretical literature of public history, articulated in Michael Frisch’s A Shared Authority, that interpretive and meaning-making authority in public history is inherently shared. Each case study reveals different factors that either promote or preclude more balanced power dynamics between the museums and their communities within the broader power dynamics established by the grant. Staff reflection-in-action, project activity and partner museum choice, and the non-American public history and museological contexts are all revealed to uniquely influence the dynamics between the museums and their communities. Throughout, the agency of the non-American participants, highlighted through the responses and reactions to the unequal dynamics of the projects, complicates notions of the singular democratic public sphere that underpin the paradigm of the museum as forum.

International Telemetering Conference Proceedings / October 25-28, 1999 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper presents the future of optical networking via photonic switches as a potential replacement for the existing electronic cross-connects. Although optical amplifiers are now mainstream and wave division multiplexing (WDM) systems are a commercial reality, the industry’s long-term vision is one of the all-optical network. This will require optical switching equipment such as all-optical or “photonic” cross-connect switches that will provide packet switching at an optical layer. Currently, as voice calls or data traffic are routed throughout Range and commercial networks, the information can travel through many fiber-optic segments which are linked together using electronic cross-connects. However, this electronic portion of the network is the bottleneck that is preventing the ideal network from achieving optimal speeds. Information is converted from light into an electronic signal, routed to the next circuit pathway, then converted back into light as it travels to the next network destination. In an all-optical network, the electronics are removed from the equation, eliminating the need to convert the signals and thereby significantly improving network performance and throughput. Removing the electronics improves network reliability and restoration speeds in the event of an outage, provides greater flexibility in network provisioning, and provides a smooth transition when migrating to future optical transmission technologies. Despite the fact that photonic switching remains uncommercialized, it now seems apparent that the core switches in both the public networks and DoD Range networks of the early 21st century will probably carry ATM cells over a photonic switching fabric.

<p>Den här rapporten undersöker distansutbildningar vid Högskolan i Kalmar, på Institutionen för kommunikation och design (IKD). Dels tas det upp hur IKD jobbar med distansstudier idag men även hur distansutbildning fungerar och hur man kan förbättra denna. Anledningen är att distansutbildningar idag är ett utvecklingsområde där det ständigt händer nya saker. Distansutbildning är kanske på väg att revolutionera sättet på vilket vi idag bedriver utbildning, både i grundskolan och upp till högskola/universitet.</p><p>Uppdraget kommer från lärarna på IKD som känner att de vill förbättra sin situation. Undersökningen genomfördes med hjälp av etnografiska studier där undervisning observerades och lärare intervjuades. De etnografiska studierna jämfördes sedan med tidigare forskning inom ämnet. Därefter gjordes en marknadsundersökning för att se vilka program som fyller dagens behov. I slutändan resulterade projektet i ett antal program som hjälper lärarna i sitt arbete med distansstudier. Förutom de program som används idag föreslås även Adobe Acrobat Connect pro. Det är ett program som har köpts in av SUNET för att fungera som e-learning programvara för svenska högskolor och universitet. Dessutom bör Smartboarden som idag är installerad i flera salar användas i större utsträckning än idag. För synkron kommunikation används idag framförallt Skype mellan lärare och studenter. En ökad användning av Skype och/eller MSN skulle öka kommunikationen och samhörigheten mellan lärarna och studenterna ytterligare.</p>

In the past, going to the movies was an event. The grand lit marquee made a statement, ushering you inside. The elaborately decorated lobby transported you to a place in your dreams where riches and opulence abound. The curtained screen marked the start of a true storied spectacle as you sat close to your friends and neighbors dressed in their Sunday best. There was no denying that the cinema was the place to see, be seen and to socialize. In contrast, today’s movie-going can be classified as more of a singular experience. You wait in long, solemn cattle lines to enter a cluttered lobby with loud video games, tacky candy machines and tunnel-like hallways. You sit in plush recliners in a sea of strangers and rush out of the theater before even the lights come up. In response to this cultural shift, my proposed design solution will challenge the isolation of today’s cinema by recreating the procession associated with neighborhood movie-going of the early 1900s. I will reinvent a cinema built in 1937, the Bellevue Theater, and develop a design that is contemporary, incorporating both modern technology and interests of today. The design will explore the spatial connections between one and many, fostering both the individual and group experience associated with the big screen – the cinema procession of the past.

In the fast changing world of a new, democratic South Africa (S.A.), the political, economic and social arenas are rapidly moving in new directions. In order to impact on important new policy developments as they are being developed and to impact on the planned changes in their fields, many adult education organisations saw the need to band together to form networks or associations and the like, through which to present their viewpoints or ideas at policy debates. In this way their views were backed by recognisable stakeholder or constituency groupings. One such networking organisation was established in 1989, well before the fastmoving, radical changes were so extreme in South Africa, namely, the Forum for the Advancement of Adult Education (FAAE). The aim of the FAAE was to inform, support and professionalize the field of Adult Education and Training via their networking activities. A t times it also acted as a structure to support: policy development. These aims continue today, although the work of the FAAE has broadened. This study looks at the role of “Networking” in Adult Education in South Africa to examine its process and its impact. The study explores the views and opinions of practitioners in different parts of South Africa and examines the case study of the FAAE as part of its data gathering, as it asks the questions: how, why, when and where does or should networking occur. What are the potential gains or problems involved in such an activity? The research design, which is a combination of qualitative and quantitative approaches, attempts to provide quantitative details which accurately portray elements of the data gathered, as well as qualitative data which reflects the rich detail of the data explored. Although networking is being explored within a specific sector or community (adult continuing education), it is hoped that this study will open up ideas and possibilities to assist networking activities in other sectors or communities. It is hoped th at this study will catalyse other studies to explore the concept of “networking” and as a consequence, that more publications addressing this issue might arise.
