Building a Collaborative Digital Collection: A Necessary Evolution in Libraries
Law libraries are losing ground in the effort to preserve information in the digital age. In part, this is due declining budgets, user needs, and a caution born from the great responsibility libraries feel to ensure future access instead of selecting a form that may not survive. That caution, though, has caused others, such as Google, to fill the silence with their vision. Libraries must stand and contribute actively to the creation of digital collections if we expect a voice in future discussion. This article presents a vision of the start of a collaborative, digital academic law library, one that will harness our collective strengths while still allowing individual collections to prosper. It seeks to identify and answer the thorniest issues - including copyright - surrounding digitization projects. It does not presume to solve all of these issues. It is, however, intended to be a call for collective action, to stop discussing the law library of the future and to start building it
Topic Modeling and Transfer Learning for Automated Surveillance of Injury Reports in Consumer Product Reviews
Many modern firms and interest groups are tasked with the challenge of monitoring the status and performance of a bevy of distinct products. As online user-generated content has increased in volume, new unstructured data sources are available for mining unique insights. Reports of injuries arising as a result of product usage are particularly concerning. In this paper, we utilize complimentary approaches to address this problem. We analyze two novel datasets; first, a government-maintained dataset of hazard and injury reports and second, a large dataset of cross-industry consumer product reviews manually coded for the presence of hazard and injury reports. We apply an unsupervised topic modeling approach to characterize the hazard and injury reports detected. Then, we implement a supervised transfer learning technique, using information obtained from the government-maintained dataset to detect hazard and injury reports in online reviews. Our results offer improved surveillance for monitoring hazards across multiple industries
Developing Engineering Learning Objects Online Portal with LabVIEW and an Open Source Web Content Management System
Learning objects (LOs) are independent chunks of knowledge normally used for instructional or learning purposes. LOs are normally reusable in the sense that they can be adopted and adapted for various learning and instructional scenarios. They are also tagged with metadata which includes descriptive information allowing them to be used and searched easily. LOs are sometimes metaphored as being a LEGO. Examples of LOs could contain multimedia content, instructional content, learning objectives, instructional software and software tools, and computer simulations. Many LOs are designed to be mediated online.
In engineering education, computer simulations based learning objects could be the most beneficial for conveying hard engineering concepts for the engineering science learner. Computer simulations have been reported to facilitate conceptual understanding and leaving positive impact on students learning in numerous number of engineering education research articles. In the last two decades, many software packages have been developed for enhancing the engineering design and analysis process, examples are Matlab/Simulink, PSpice, LabVIEW, etc. These has been used consequently by academics for enhancing their students learning. LabVIEW is one of the most versatile computer software packages. It is used comprehensively in the industry as well as in academia. LabVIEW started as computer software interface of PC based data question equipments, however, it has grown much beyond that offering comprehensive toolkits and already implemented functions. Also it has great connectivity facilities with Matlab/Simulink, C++, and Visual Basic allowing communicating already developed codes in the latter with its core engine. The other important specification of LabVIEW is its embedded internet tools enabling publishing its programmed GUIs on the world wide web in easy and handy way.
Web content management systems is the third generation of web publishing applications after HTML and web authoring software packages such as FrontPage and Dreamweaver. It is used to manage and control a large, dynamic collection of Web material (HTML documents and their associated images). A WCMS facilitates content creation, content control, editing, and many essential Web maintenance functions. In contrast with the web development tools such as HTML, FrontPage, Dreamweaver, etc., a CMS enables faster development, cost effectiveness, and online flexibility. The basic idea of any web content management system is that a non-technical person often needs to be able to keep their own website up-to-date without having to call on a web developer to make changes every time. Of course there are some things that can only be done by a web developer, but for simpler tasks such as changing the wording of a paragraph, it is an unnecessary burden and expense for both parties if you have to get a developer to make the changes.
This paper provides an A to Z prescription of implementing a standardized Learning Objects online portal. This describing in detail a LabVIEW based Learning Object architecture, using a proper IEEE LOM metadata generation tool, and finally how on the top of that a Joomla web content management system can be used for developing the online portal
Scribd case study : commercial viability of the e-book subscription business model
Modeled after media subscription giants Netflix and Spotify, Scribd is a subscription e-book service
based in San Francisco, United States. Despite the highly evaluated potential of the business model,
Scribd came across significant problems due to a combination of a pay-per-read payout model and
all-you-can-read pricing model; these issues led to a few unpopular decisions such as reducing
content selection and eventually changing the subscription terms.
In presence of a powerful and prosperous competitor such as Amazon that has a direct analogue to
Scribd, Amazon Kindle Unlimited, Scribd has to choose growth strategies that will allow it to add
value to the product for current and potential customers. The two possible strategies discussed in
this case study are an international expansion to Germany and a domestic market expansion through
the premium segment. The case study provides relevant data to assess each strategy and gives
background information about the company and the industry in order for students to analyze the
case and decide on the most attractive strategy to follow.Modelado como os gigantes de serviço de assinatura de média como Netflix e Spotify, Scribd é um
serviço de assinatura de e-book baseado em São Francisco, Estados Unidos. Apesar de o modelo de
negócio ter grande potencial, Scribd encontrou problemas significativos devido a uma combinação
do seu modelo de pagamento "pago por leitura" e modelo de precário "tudo o que consegue ler".
Estes problemas resultaram em decisões pouco populares, como a redução do conteúdo disponÃvel,
e a eventual mudança dos termos de assinatura.
Na presença de competição potente e próspera como a da Amazon, que tem um serviço equivalente
em Amazon Kindle Umlimited, Scribd tem que escolher uma estratégia de crescimento que o vai
possibilitar de adicionar valor ao produto para clientes existentes e potenciais. As duas estratégias
possÃveis que são discutidas neste caso de estudo são uma expansão international para o mercado
alemão, e uma expansão no mercado doméstico através de um segmento "premium". Este caso de
estudo disponibiliza dados relevantes para avaliar cada estratégia, e fornece informação de fundo a
cerca da empresa e a indústria, para que os alunos possam analisar o caso e decidir qual estratégia
será a mais atrativa para seguir
Migration from client/server architecture to internet computing architecture
The Internet Computing Architecture helps in providing a object-based infrastructure that can be used by the application developers to design, develop, and deploy the ntiered enterprise applications and services. For years of distributed application development, the Internet Computing Architecture has helped in providing various techniques and infrastructure software for the successful deployment of various systems, and established a foundation for the promotion of re-use and component oriented development. Object-oriented analysis is at the beginning of this architecture, which is carried through deploying and managing of finished systems. This architecture is multi-platform, multi-lingual, standards-based, and open that offers unparalleled integration capability. And for the development of mission critical systems in record time it has allowed for the reuse of the infrastructure components. This paper provides a detailed overview of the Internet Computing Architecture and the way it is applied to designing systems which can range from simple two-tier applications to n-tier Web/Object enterprise systems. Even for the best software developers and managers it is very hard to sort through alternative solutions in today\u27s business application development challenges. The problems with the potential solutions were not that complex now that the web has provided the medium for large-scale distributed computing. To implement an infrastructure for the support of applications architecture and to foster the component-oriented development and reuse is an extraordinary challenge. Further, to scale the needs of large enterprises and the Web/Internet the advancement in the multi-tiered middleware software have made the development of object-oriented systems more difficult. The Internet Computing Architecture defines a scaleable architecture, which can provide the necessary software components, which forms the basis of the solid middleware foundation and can address the different application types. For the software development process to be component-oriented the design and development methodologies are interwoven. The biggest advantage of the Internet Computing Architecture is that developers can design object application servers that can simultaneously support two- and three-tier Client/Server and Object/Web applications. This kind of flexibility allows different business objects to be reused by a large number of applications that not only supports a wide range of application architectures but also offers the flexibility in infrastructure for the integration of data sources. The server-based business objects are managed by runtime services with full support for application to be partitioned in a transactional-secure distributed environment. So for the environments that a supports high transaction volumes and a large number of users this offers a high scaleable solution. The integration of the distributed object technology with protocols of the World Wide Web is Internet Computing Architecture. Alternate means of communication between a browser on client machine and server machines are provided by various web protocols such as Hypertext Transfer Protocol and Internet Inter-ORB Protocol [NOP]. Protocols like TCP/IP also provides the addressing protocols and packetoriented transport for the Internet and Intranet communications. The recent advancements in the field of networking and worldwide web technology has promoted a new network-centric computing structure. World Wide Web evolves the global economy infrastructure both on the public and corporate Internet\u27s. The competition is growing between technologies to provide the infrastructure for distributed large-scale applications. These technologies emerge from academia, standard activities and individual vendors. Internet Computing Architecture is a comprehensive, open, Network-based architecture that provides extensibility for the design of distributed environments. Internet Computing Architecture also provides a clear understanding to integrate client/server computing with distributed object architectures and the Internet. This technology also creates the opportunity for a new emerging class of extremely powerful operational, collaboration, decision support, and e-commerce solutions which will catalyze the growth of a new networked economy based on intrabusiness, business -to-business (B2B) and business-to-consumer (B2C) electronic transactions. These network solutions would be able to incorporate legacy mainframe systems, emerging applications as well as existing client/server environment, where still most of the world\u27s mission-critical applications run. Internet Computing Architecture is the industry\u27s only cross-platform infrastructure to develop and deploy network-centric, object-based, end-to-end applications across the network. Open and de facto standards are at the core of the Internet computing architecture such as: Hyper Text Transfer Protocol (HTTP)/ Hyper Text Markup Language (HTML)/ Extensible Markup Language (XML) and Common Object Request Broker Architecture (CORBA). It has recognition, as the industry\u27s most advanced and practical technology solution for the implementation of a distributed object environment, including Interface Definition Language (IDL) for languageneutral interfaces and Internet Inter Operability (MOP) for object interoperability. Programming languages such as JAVA provides programmable, extensible and portable solutions throughout the Internet Computing Architecture. Internet Computing Architecture not only provides support, but also enhances ActiveX/Component Object Model (COM) clients through open COM/CORBA interoperability specifications. For distributed object-programming Java has also emerged as the de facto standard within the Internet/Intranet arena, making Java ideally suited to the distributed object nature of the Internet Computing Architecture. The portability that it offers across multi-tiers and platforms support open standards and makes it an excellent choice for cartridge development across all tiers
Growth of relational model: Interdependence and complementary to big data
A database management system is a constant application of science that provides a platform for the creation, movement, and use of voluminous data. The area has witnessed a series of developments and technological advancements from its conventional structured database to the recent buzzword, bigdata. This paper aims to provide a complete model of a relational database that is still being widely used because of its well known ACID properties namely, atomicity, consistency, integrity and durability. Specifically, the objective of this paper is to highlight the adoption of relational model approaches by bigdata techniques. Towards addressing the reason for this in corporation, this paper qualitatively studied the advancements done over a while on the relational data model. First, the variations in the data storage layout are illustrated based on the needs of the application. Second, quick data retrieval techniques like indexing, query processing and concurrency control methods are revealed. The paper provides vital insights to appraise the efficiency of the structured database in the unstructured environment, particularly when both consistency and scalability become an issue in the working of the hybrid transactional and analytical database management system
