    With the contributions of international experts, the book aims to explore the new boundaries of universal bibliographic control. Bibliographic control is radically changing because the bibliographic universe is radically changing: resources, agents, technologies, standards and practices. Among the main topics addressed: library cooperation networks; legal deposit; national bibliographies; new tools and standards (IFLA LRM, RDA, BIBFRAME); authority control and new alliances (Wikidata, Wikibase, Identifiers); new ways of indexing resources (artificial intelligence); institutional repositories; new book supply chain; “discoverability” in the IIIF digital ecosystem; role of thesauri and ontologies in the digital ecosystem; bibliographic control and search engines

    Continuous Delivery in Data Warehousing

    Tämän väitöskirjan motivaatio kumpuaa käytännön ongelmasta: kuinka lyhentää aikaa ideasta analysoida jotain siihen, että analyysi on käyttäjien saatavilla. Tietovarastointia on perinteisesti pidetty monimutkaisena ja siten herkkänä virheille. Tietovarastoinnissa erilliset vaiheet tapahtuvat peräkkäin ennalta määritellyssä järjestyksessä. Perinteinen tapa tietovarastoinnissa on ottaa koko ratkaisu kerralla tuotantokäyttöön, jossa kaikki tietovaraston palaset ovat paikoillaan ennen tuotantokäyttöä. Mikäli kehitys seuraa lyhyitä iteraatioita, miksi käyttöönotot tuotantoon eivät seuraa näitä iteraatioita? Tämä väitöskirja esittelee kuinka raportointi- ja tietovarastointitiimit voivat rakentaa yhtäaikaa raportointiratkaisuja (business intelligence) vaiheittain. Yhteistyö tehostaa kehittäjien välistä kommunikaatiota ja lyhentää palautesykliä loppukäyttäjältä kehittäjille mikä tekee palautteesta suorempaa. Jatkuvan käyttöönoton käytännöt tukevat julkaisemista usein tuotantoympäristöön. Kaksikerroksinen tietovarastoarkkitehtuuri erottaa analyyttisen ja tapahtumapohjaisen käsittelyn. Erilaisten käsittelyjen erottaminen mahdollistaa paremman testauksen ja siten jatkuvan käyttöönoton. Käytettäessä jatkuvaa käyttöönottoa, voidaan kehitysaikaa lyhentää myös automatisoimalla tietomuunnosten toteutustyötä. Tämä väitöskirja esittelee tietomallin tietomuunnosten automatisoinnin toteuttamista varten, niin tiedon saattamiseksi tietovarastoon kuin tiedon hyödyntämiseen tietovarastosta. Tutkimuksen arvioinnissa noudatettiin suunnittelutieteen suuntaviivoja. Tutkimus tehtiin yhteistyössä teollisuuden ja yliopistojen kanssa. Näitä ideoita on testattu todellisissa projekteissa lupaavin tuloksin ja siten ne on todistettu toimiviksi.Continuous delivery is an activity in the field of continuous software engineering. Data warehousing, on the other hand, lie within information systems research. This dissertation combines these two traditionally separate concerns of continuous delivery and data warehousing. This dissertation’s motivation stems from a practical problem: how to shorten the time from a reporting idea until it is available for users. Data warehousing has traditionally been considered tedious and delicate. In data warehousing, distinct steps take place one after another in a predefined unalterable sequence. Another traditional aspect of data warehousing is bringing everything at once to a production environment, where all the pieces of a data warehouse are in place before production use. If development follows agile iterations, why are the releases in production not following the same iterations? This dissertation introduces how reporting and data warehouse teams can synchronously build business intelligence solutions in increments. Joint working enhances communication between developers and shortens the feedback cycle from an end-user to developers, and makes the feedback more direct. Continuous delivery practices support releasing frequently to a production environment. A two-layer data warehouse architecture separates analytical and transactional processing. Separating different processing targets enables better testing and, thus, continuous delivery. When frequently deploying with continuous delivery practices, automating transformation creation in data warehousing reduces the development time. This dissertation introduces an information model for automating the implementation of transformations, getting data into a data warehouse and getting data out of it. The research evaluation followed the design science guidelines. Research for this dissertation collaborated with the industry. These ideas have been tested on real projects with promising results, and thus they have been proven to work

    These proceedings contain research papers that were accepted for presentation at the 14th International Conference Inter-Eng 2020 ,Interdisciplinarity in Engineering, which was held on 8–9 October 2020, in Târgu Mureș, Romania. It is a leading international professional and scientific forum for engineers and scientists to present research works, contributions, and recent developments, as well as current practices in engineering, which is falling into a tradition of important scientific events occurring at Faculty of Engineering and Information Technology in the George Emil Palade University of Medicine, Pharmacy Science, and Technology of Târgu Mures, Romania. The Inter-Eng conference started from the observation that in the 21st century, the era of high technology, without new approaches in research, we cannot speak of a harmonious society. The theme of the conference, proposing a new approach related to Industry 4.0, was the development of a new generation of smart factories based on the manufacturing and assembly process digitalization, related to advanced manufacturing technology, lean manufacturing, sustainable manufacturing, additive manufacturing, and manufacturing tools and equipment. The conference slogan was “Europe’s future is digital: a broad vision of the Industry 4.0 concept beyond direct manufacturing in the company”

    Triple Helix as a Strategic Tool to Fast-Track Climate Change Adaptation in Rural Kenya: Case Study of Marsabit County

    Get PDF
    AbstractThe lack of affordable, clean, and reliable energy in Africa's rural areas forces people to resort to poor quality energy source, which is detrimental to the people's health and prevents the economic development of communities. Moreover, access to safe water and food security are concerns closely linked to health issues and children malnourishment. Recent climate change due to global warming has worsened the already critical situation.Electricity is well known to be an enabler of development as it allows the use of modern devices thus enabling the development of not only income-generating activities but also water pumping and food processing and conservation that can promote socioeconomic growth. However, all of this is difficult to achieve due to the lack of investors, local skills, awareness by the community, and often also government regulations.All the above mentioned barriers to the uptake of electricity in rural Kenya could be solved by the coordinated effort of government, private sector, and academia, also referred to as Triple Helix, in which each entity may partially take the other's role. This chapter discretizes the above and shows how a specific county (Marsabit) has benefited from this triple intervention. Existing government policies and actions and programs led by nongovernmental organizations (NGOs) and international agencies are reviewed, highlighting the current interconnection and gaps in promoting integrated actions toward climate change adaptation and energy access

    African Handbook of Climate Change Adaptation

    This open access book discusses current thinking and presents the main issues and challenges associated with climate change in Africa. It introduces evidences from studies and projects which show how climate change adaptation is being - and may continue to be successfully implemented in African countries. Thanks to its scope and wide range of themes surrounding climate change, the ambition is that this book will be a lead publication on the topic, which may be regularly updated and hence capture further works. Climate change is a major global challenge. However, some geographical regions are more severly affected than others. One of these regions is the African continent. Due to a combination of unfavourable socio-economic and meteorological conditions, African countries are particularly vulnerable to climate change and its impacts. The recently released IPCC special report "Global Warming of 1.5º C" outlines the fact that keeping global warming by the level of 1.5º C is possible, but also suggested that an increase by 2º C could lead to crises with crops (agriculture fed by rain could drop by 50% in some African countries by 2020) and livestock production, could damage water supplies and pose an additonal threat to coastal areas. The 5th Assessment Report produced by IPCC predicts that wheat may disappear from Africa by 2080, and that maize— a staple—will fall significantly in southern Africa. Also, arid and semi-arid lands are likely to increase by up to 8%, with severe ramifications for livelihoods, poverty eradication and meeting the SDGs. Pursuing appropriate adaptation strategies is thus vital, in order to address the current and future challenges posed by a changing climate. It is against this background that the "African Handbook of Climate Change Adaptation" is being published. It contains papers prepared by scholars, representatives from social movements, practitioners and members of governmental agencies, undertaking research and/or executing climate change projects in Africa, and working with communities across the African continent. Encompassing over 100 contribtions from across Africa, it is the most comprehensive publication on climate change adaptation in Africa ever produced

    AbstractThe vulnerability of agriculture systems in Africa to climate change is directly and indirectly affecting the availability and diversity of plants and plant products available in local markets. In this chapter, markets in Benin City and environs were assessed to document the availability of plants and plant products. Markets were grouped into urban, suburban, and rural with each group having four markets. Majority of the plant and plant product vendors were women and 88 plant species belonging to 42 families were found. Their scientific and common names were documented as well as the parts of the plant and associated products available in the markets. Most of the plant and plant products found in local markets belong to major plant families. Urban markets had the highest diversity of plants and plant products. Three categories of plants and plant products were documented. Around 67% of the plants and plant products were categorized as whole plant/plant parts, 28% as processed plant parts, while 5% as reprocessed plant/plant parts. It was revealed that 86% of these plants are used as foods, 11% are for medicinal purposes, while 3% is used for other purposes. About 35% of plants and plant products across the markets were fruits, which is an indication that city and environs are a rich source of fruits. The local knowledge and practices associated with the plants and plant products can contribute towards formulating a strategic response for climate change impacts on agriculture, gender, poverty, food security, and plant diversity
