Narrowing the gap of the digital divide
Xu, Xiaomu; Leng, Ling
2019 - English
In China, a digital divide results from geographical conditions, unbalanced economic development, individual differences, and other factors. To bridge this gap and to weaken the polarisation between the “information wealthy” and the “information poor,” a federal, Internet-based library, the National Science and Technology Library (NSTL), has been founded. This paper will introduce what NSTL is and how NSTL contributes to narrowing the gaps in order to reduce differences between the two groups in access to science and technology information and resources. NSTL consists of 9 library members, all of which are national authoritative libraries in different disciplines, respectively covering the natural sciences, engineering, agriculture, medicine, standards, and other fields. First, to narrow the gap caused by geographical conditions, NSTL has built 40 service stations covering 29 provinces, thus forming a nationwide information service network with the help of local and industrial scientific information institutions. This action not only guarantees resource sharing to the whole country, but also improves the service abilities of local providers. Second, to narrow the gap caused by unbalanced economic development, approximately 25,000 types of print resources that are state-funded can be unconditionally supplied to the public at reasonable prices, especially with low prices for remote and poor areas. Document delivery services are ordered over 400,000 times every year. Nearly 4,000 kinds of electronic journals are free for all domestic welfare and educational group users via Internet protocol address permissions. Third, to narrow the gap caused by individual differences, NSTL provides an integrated discovery system on the basis of unified cataloguing so that everyone can search literature easily. NSTL also organises trainings and seminars across the country, introducing and promoting resources to all communities. In addition, NSTL strives to explore approaches to international information access and to foster cooperation opportunities in order to close the gaps between countries.

Cuhadar, Sami; Cimen, Ertugrul; Turan, Abdullah
2019 - English
Library in-transit services provided between various campuses of a university are important, helping to ensure user satisfaction, effective allocation of library budgets, optimum use of resources, and effective use of library spaces. In this study, 179 universities operating in Turkey were identified and selected for assessment. The methods which libraries at these universities employ to deliver information resources to users at other campuses as well as their in-transit practices are explained in detail. The paper presents the findings of a survey that was conducted at the selected university libraries in order to assess the current state and the impact of resource sharing via the in-transit method on library budgets, library spaces, and user satisfaction. The in-transit practice of Istanbul Bilgi University (BİLGİ) Library, which has a well-established in-transit policy and which keeps detailed statistics, was also used as a case study to analyze in-transit statistics and survey findings and to provide suggestions for future improvement. Design/methodology/approach: This study employed a historical and explanatory approach; statistical methods are used to analyze the results of the survey. An important outcome of the study was that it documented the current status of in-transit practices at academic universities in Turkey. The authors utilized their professional experiences in developing resource sharing and in-transit services within a university library context in Turkey in order to design the survey. Objectives: This research paper might be useful for any university librarians interested in resource sharing, effective use of library budgets, library collections, and library spaces, especially in developing countries. The paper also provides academic libraries with a set of guidelines for establishing an in-transit service. Originality/value: This paper is the first study of in-transit services provided between Turkish university libraries. It also addresses the opportunities and challenges that arise when establishing or improving in-transit services. The results of the study will be of use to university libraries, researchers, and library professionals working in the field.

When there’s only one
Eighmy Brown, Melissa; Smith, Austin; Thompson, Hilary H.
2019 - English
Electronic theses and dissertations (ETDs) are one of the many resources interspersed throughout the current environment of online content. The past two decades have witnessed a shift from print to electronic theses and dissertations and an accompanying growth in university mandates requiring deposit of ETDs in institutional repositories. While these changes should have paved the way for unfettered online access, barriers such as embargoes requested by the author and vendor licensing restrictions have also emerged, hampering access to these unpublished works. Likewise, policies governing cataloging, deposit, and repository access may differ widely across institutions, adding further complexity to the landscape. Interlibrary Loan practitioners are looking for ways to share this unique content and help users navigate the terrain despite the obstacles. This presentation will explore recent trends in thesis requesting and fulfillment using borrowing and lending requests for theses and dissertations from two U.S. public research universities, along with the perspectives of colleagues at peer institutions. These data sets demonstrate that the demand for these materials extends across borders, raising the question: how can we encourage the sharing of ETDs on a global scale? The authors hope their research on the accessibility of theses and dissertations will inform the international academic community on ways to improve the sharing of these important institutional assets, including raising awareness of the need for a policy and workflow that permits controlled ILL lending of embargoed ETDs that mirrors lending of print dissertations.

International interlibrary loan in a changing environment
Munson, Kurt; Thompson, Hilary H.
2019 - English
In 2019 the American Library Association (ALA) Reference & User Services Association’s Sharing and Transforming Access to Resources Section (RUSA STARS) International Interlibrary Loan Committee conducted its fourth survey of international interlibrary loan policies and practices. This survey was widely distributed to libraries worldwide, in coordination with IFLA’s Document Delivery & Resource Sharing Section, including for the first time translations in six of the seven official IFLA languages. While reusing questions from prior survey instruments allowed for longitudinal analysis of quantitative data, the 2019 survey also included new open response questions that delve deeper into how the global library community can build upon its success in sharing resources across borders in order to improve this service for future users. On behalf of the committee, the authors will present select survey results, focusing on the evolving role of international ILL in an increasingly complex resource discovery and delivery ecosystem. Data-informed strategies to overcome challenges currently facing this service and to optimize global delivery solutions will be shared.

Analýza lomových procesů při kolapsech kalder
Kabele Petr; Michael Somr; Šejnoha Michal
2019 -
Kaldery jsou sopečné propadliny způsobené poškozením stropu magmatického krbu v důsledku změn tlaku uvnitř krbu. Vznik kaldery je doprovázen kruhovými zlomy, jejichž vznik se obvykle projevuje erupcemi velkých objemů pyroklastického materiálu do zemské atmosféry a představuje tak vážné nebezpečí pro životní prostředí, klima a lidskou společnost. Hlubší porozumění geologickým podmínkám, za kterých se tyto události mohou vyskytnout, má proto velký význa. Geologický průzkum a terénní studie mohou obvykle studovat pouze povrchové projevy magmatických procesů probíhajících pod zemským povrchem. V tomto ohledu se numerická analýza ukázala jako klíčový nástroj pro pochopení mechanických podmínek kolapsu kaldery. S cílem posunout současný stav vědění a přinést nové pohledy na poškození předcházející vzniku kaldery pomocí matematického modelování, numerických simulací a analýz byla provedena rozsáhlá rešerša. Na základě rešerše byly definovány sporné otázky, které jsou stále předmětem diskuse ve výzkumné komunitě a posloužily tak jako cíle pro tuto práci.K dosažení těchto cílů byla v této práci využita metoda konečných prvků (MKP). Aby byly simulace realistické a zároveň proveditelné, byla vybrána vhodná strategie modelování, materiálové modely a parametry a zjednodušující předpoklady. Následně bylo vyhodnoceno mnoho případů magmatických krbů. Zvolená strategie modelování použitá v této práci ukazuje, že vývoj tlaku v magmatické komoře se projevuje řadou různých porušení okolní horniny. Tato poškození nejsou omezena pouze na tvorbu různých kruhových zlomů, ale mohou také zahrnovat další typy poškození. Tato strategie modelování také umožňuje zachytit mnoho vlastností kruhových zlomů, které se projevují při jejich šíření.Calderas are volcanic depressions caused by rupturing of a magma chamber roof as a consequence of pressure evolution inside the chamber. The collapse of a caldera is accommodated by ring faults, whose formation is commonly accompanied by ejection of large volumes of pyroclastic material to the Earth's atmosphere and thus represents severe volcanic hazards for the environment, climate, and human society. A deeper understanding of geological conditions under which these events can occur is thus of great importance and interest. Geological survey and field studies can usually access just surface manifestation of immense magmatic processes taking place under the Earth's surface. In this respect, numerical analysis has proven as a key tool in understanding the mechanical conditions of caldera collapse.In order to advance the knowledge and bring new views on fracturing processes preceding caldera collapse through mathematical modeling, numerical simulations, and analysis, extensive research was carried out. Based on a state-of-the-art review, outstanding issues, which are still a subject of debate in the research community, were identified and provided the objectives for the thesis.To achieve the goals, the finite element method (FEM) was employed in this work due to its capabilities and universality. To make the FE simulations realistic, yet feasible, appropriate modeling strategy, material models and parameters, and simplifying assumptions were selected. Subsequently, many cases covering a wide range of possible magma chamber geometries were calculated. The modeling strategy employed in this work demonstrates that pressure evolution inside a magma chamber is manifested by a range of fracturing processes in the host rock. These processes are not restricted to the formation of various ring faults alone but may also include radial and circumferential fracturing, surface tearing, magmatic stoping, and cauldron subsidence. The modeling strategy also enables capturing, orientation (inward-dipping, vertical, outward-dipping), mode (shear or extension), and direction (upwards, downwards) of a ring fault initiation and growth.

Nanotechnologie jako v současnosti jedna z nejprogresivněji se rozvíjející oblastí lidského bádání nabízí příležitost pro rozvoj četných aplikací nanočástic v koncových produktech. Stále větší spotřeba nanočástic v měřítku celosvětového trhu klade vysoké nároky na výrobní technologie, které musejí produkovat nanočástice v požadované kvalitě, s minimálními náklady a v co největším množství. To vše vyvolává zvýšené požadavky na ekonomičnost výrobních procesů. Za tímto účelem je třeba podrobit výrobní procesy důsledné nákladové analýze pomocí kalkulace nákladů na životní cyklus. Tato disertační práce Modelování nákladů na celoživotní cyklus nanomateriálů se zaměřuje na ekonomické hodnocení nákladů celého životního cyklu výroby nanomateriálů pomocí návrhu komplexního nákladového modelu, který je schopný sloužit jako podpora manažerského rozhodování v oblasti plánování výrobních kapacit, optimalizace využití výrobních prostředků a prověření výrobní strategie. Do modelu je zakomponován modul volby zajištění výrobních prostor a modul volby strategie údržby. Celkový pohled na náklady životního cyklu je v modelu rozšířen o hodnocení vlivu vnějších faktorů a gravitačního efektu trhu ovlivňující strategické rozhodnutí o umístnění výrobního podniku. Tyto vlivy působící na podnik mohou ovlivnit souhrnnou bilanci investičního projektu, což je důležitý aspekt, který je třeba mít na zřeteli.Nanotechnology, one of the most progressive areas of human research, is now an opportunity to develop many applications of nanoparticles in the final products. The increasing consumption of nanoparticles on a global market causes higher requests for manufacturing technologies that have to produce nanoparticles in the required quality, with minimal costs and in the greatest possible amount. All this leads to increased demands on the economics of production processes. Therefore the production processes must be verify by cost analysis of life cycle costing. This dissertation thesis is called The modeling of costs for the life cycle of nanomaterial. It is focused on the economic assessment of the life cycle costs of nanomaterials by designing a complex cost model and it extends the assessment to quantify the impact of the market's gravitational effect affecting the strategic decision to locate a manufacturing enterprise. These influences may affect the balance of the project that is an important aspect which must be kept in mind.
