Enterprise architecture – the foundation for a strategy

This artcle describes work done with enterprise architecture of the National Digital Library. The National Digital Library is an initiative of the Finnish Ministry of Education and Culture. Its purpose is to promote the availability of the digital information resources of archives, libraries and museums, and to develope the long-term preservation of digital cultural heritage materials. Enterprise architectures are a tool for strategic management and planning. An enterprise architecture also functions as an aid at a more practical level. It shows, for example, what kind of changes and improvements may be made in one system without overlap or conflict with other systems.

Porin Kuudennen osan tarinoista rakennettu kulttuuriperintö

Tutkimus käsittelee viranomaisten ja asukkaiden välistä vuorovaikutusta kaavaprosessin aikana. Tutkimusalueena on valtakunnallisesti merkittäväksi kulttuuriympäristöksi luokiteltu Porin Kuudes osa, joka on yksi laajimmista yhtenäisenä säilyneistä 1800-luvun lopun puukaupunkialueista Suomessa. Hermeneuttis-fenomenologista otetta soveltava tutkimus perustuu muistitietoaineistoon, joka avaa näkökulman paikallisen kulttuuriperinnön syntymiseen, periytymiseen ja muutokseen. Kuudennen osan vuonna 2012 voimaan tulleessa asemakaavamuutoksessa suojeltiin 405 rakennusta. Sekä viranomaiset että asukkaat haluavat säilyttää arvokkaan ympäristön jälkipolville. Asukkaiden ja viranomaisten lähtökohdat arvottamiselle ovat kuitenkin erilaiset. Asiantuntijoiden näkemys kulttuuriympäristön arvoista perustuu eksplisiittiseen viralliseen tietoon, joka heijastaa positivistista käsitystä maailmasta mitattavista objekteista koostuvana kokonaisuutena. Asukkaiden arvostus asuinaluetta ja sen rakennuksia kohtaan puolestaan nousee sukupolvelta toiselle siirretyn aineettoman perinnön yhteisöllisestä merkityksestä. Heidän kokemuksensa kiteytyy kodin ja kotiseudun käsitteissä ja se tuodaan esiin rakennuksiin liittyvissä tarinoissa. Tulkinta on virallista tietoa haastavaa ja täydentävää. Kestäviä suojelupäätöksiä voidaan tehdä vain viranomaisten ja asukkaiden väliseen tasa-arvoiseen vuoropuheluun perustuen. Tutkimus nostaa asukkaiden kokemuksellisen, paikkaan sitoutuneen hiljaisen tiedon virallisen tiedon rinnalle, kulttuurisesti kestävän maankäytön suunnittelun perustaksi. Koska ihminen toimii sellaisten asioiden puolesta, jotka hän kokee arvokkaaksi, asukaslähtöinen rakennussuojelu on lähtökohtaisesti yhteisön omakseen kokeman aineettoman kulttuuriperinnön suojelua.

Post-industrial 2.0 – Social Web as the second coming of the post-industrial society

This study presents a review of theories of the so-called post-industrial society, and proposes that the concept of post-industrial society can be used to understand the recent developments of the World Wide Web, often described as Web 2.0 or social Web. The study combines theories ranging from post-war management science and cultural studies to software development, and tries to build a holistic view of the development of the post-industrial society, and especially the Internet. The discourse on the emergence of a post-industrial society after the World Wars has addressed the ways in which the growing importance of information, and innovations in digital communications technology, are changing our society. It is furthermore deeply connected with the discourse on the postmodern society, which emphasizes cultural fragmentation, intertextuality, and pluralism. The Internet age is characterized by increasing masses of information that are managed through various technologies. While 1990s Internet technologies often used the network as a traditional broadcasting channel with added interactivity, Web 2.0 technologies are specifically designed to utilize the network model by facilitating communication between various services and devices, and analyzing the relationships between users and objects in order to produce intelligent insight. The wide adoption of the Internet, and recently of Internet-enabled mobile devices, is furthermore continuously producing new ways of communicating, consuming, and producing. Applications of the social Web, such as social media or social networking services, are permanently changing our traditional social, cultural, and economic practices. The study first presents an overview of the post-industrial society, the Internet, and the concept of Web 2.0. Then the concept of social Web is described with an analysis of the term social media, the brief histories of the interactive Web and social networking services, and a description of the concept ―long tail‖, used to represent the masses of information available in the Web that do not receive mainstream attention. Finally, methods for retrieving and filtering information, modeling social and cultural relationships, and communicating with customers, are presented.

Formal modelling for digital media distribution

Human beings have always strived to preserve their memories and spread their ideas. In the beginning this was always done through human interpretations, such as telling stories and creating sculptures. Later, technological progress made it possible to create a recording of a phenomenon; first as an analogue recording onto a physical object, and later digitally, as a sequence of bits to be interpreted by a computer. By the end of the 20th century technological advances had made it feasible to distribute media content over a computer network instead of on physical objects, thus enabling the concept of digital media distribution. Many digital media distribution systems already exist, and their continued, and in many cases increasing, usage is an indicator for the high interest in their future enhancements and enriching. By looking at these digital media distribution systems, we have identified three main areas of possible improvement: network structure and coordination, transport of content over the network, and the encoding used for the content. In this thesis, our aim is to show that improvements in performance, efficiency and availability can be done in conjunction with improvements in software quality and reliability through the use of formal methods: mathematical approaches to reasoning about software so that we can prove its correctness, together with the desirable properties. We envision a complete media distribution system based on a distributed architecture, such as peer-to-peer networking, in which different parts of the system have been formally modelled and verified. Starting with the network itself, we show how it can be formally constructed and modularised in the Event-B formalism, such that we can separate the modelling of one node from the modelling of the network itself. We also show how the piece selection algorithm in the BitTorrent peer-to-peer transfer protocol can be adapted for on-demand media streaming, and how this can be modelled in Event-B. Furthermore, we show how modelling one peer in Event-B can give results similar to simulating an entire network of peers. Going further, we introduce a formal specification language for content transfer algorithms, and show that having such a language can make these algorithms easier to understand. We also show how generating Event-B code from this language can result in less complexity compared to creating the models from written specifications. We also consider the decoding part of a media distribution system by showing how video decoding can be done in parallel. This is based on formally defined dependencies between frames and blocks in a video sequence; we have shown that also this step can be performed in a way that is mathematically proven correct. Our modelling and proving in this thesis is, in its majority, tool-based. This provides a demonstration of the advance of formal methods as well as their increased reliability, and thus, advocates for their more wide-spread usage in the future.

Pinning Down Identity in Social Media: Food Cultural Transfer on Pinterest

This research has been conducted within the realm of where today’s digital media society and the timeless concept of cultural identity overlap. The aim of this thesis is to explore the nature of online cultural identity management. By focusing on the social media platform, Pinterest, this study considers the food-pinning behavior of a group of Americans living in Finland and connects their online actions with their cultural identity. Through an examination of Pinterest as a social space, and even a third place, the relative theoretical literature provides and interesting background for a contemporary discussion on the matter. Literature on food as a cultural marker is also brought into consideration. Using the methods of introspection and an adapted version of virtual ethnography, a study was conducted, and ultimately, the analysis of data obtained from the Pinterest boards of ten individuals shows that the vast majority of food-related information in this setting is US-sourced. A questionnaire provides further insight into the individuals’ Pinterest usage. I argue that pinning is an act of online identity management, whether it is a conscious act or a situational effect, and that using Pinterest maintains and even strengthens these individuals’ cultural identity as Americans. This study adds to current discussions pertaining to transnationalism, globalization, and online cultural identity, as well as opens channels for further research on this dynamic topic, which is needed to understand ourselves as cultural beings in the digital age.
