Abstract:
Today, the use of traditional reference desk in the academic libraries has been rarely used, thus expanding or even move to a virtual reference service. A minimum level of virtual reference services are provided in the academic library is currently in general is the electronic mail (e-mail). One of the academic library specifically provide virtual reference services via e-mail is a Petra Christian University (PCU) Library (refdesk@petra.ac.id.). In such services librarians provide assistance to users in finding information and answer questions. This study aimed to analyze the transaction reference services virtually through e-mail at the PCU Library, with a view of the types of questions based on user background, the writing style of language communication interaction used based on user background, and cultural values are revealed behind the user in virtual reference services (e-mail). This study uses content analysis (content analysis) of the transcript e-mail received librarians of reference services began March 10 until June 16, 2015. The results showed that the types of questions asked in reference service virtual (e-mail) in the Library UK Petra include: specific search, access online resources, operation of online resources, policies and procedures for services, and library holdings with background the student (PCU and non-PCU), faculty, and librarians. Based on the background of users found that overall more types of questions asked in virtual reference services (e-mail) is a problem of access to online resources, and generally submitted by the students. Then, the writing style of the user's language in interaction reference service virtual (e-mail) tends to be formal, which includes the word greeting, the message will be delivered, and regards cover, either by the student (PCU and non-PCU), lecturer, or librarians. While cultural values that revealed the background behind the user in virtual reference services (e-mail) is obedience, courtesy and politeness users.

Abstract:
Based on the author’s detailed analysis of the archive of completed references, the specific classification of lexicographic references is introduced. The virtual lexicographical references are the result of joint efforts of bibliographers and lexicographers. This type of reference holds a specific place in bibliographic reference user service. Polyfunctionality and specific diversity make information specific features of this type of references. The focus is made on the subtypes of the lexicographic references; the examples are provided. Potential lexicographical and bibliographic services are suggested for the libraries’ virtual environment to support user self-education and self-service and intensive use of lexicographic information. The article is complemented by the table to present the classification of lexicographic virtual references.

Abstract:
The rapid advancements in web and availability of growing number of free social networking tools have greatly influenced the present day communication mechanisms. These tools have provided cheaper, instant and faster methods of communicating information irrespective of geographical and time barriers. Users especially the younger generation is much familiar with the use of such tools and modern libraries are experiencing rapid changes in user perceptions and information seeking patterns. Owing to the ease of accessibility of plethora of information resources via cell phones, tablets using smart apps, libraries are revisiting their methods of information delivery. Many libraries are using social networking tools for handling user queries and advertising their library products especially in Virtual Reference Services (VRS). Virtual reference is reference service initiated electronically where patrons employ computers or other technology to communicate with public services staff without being physically present. Communication channels used frequently in virtual reference include chat, video-conferencing, voice-over-IP, co-browsing, e-mail, and instant messaging (Reference and User Services Association [RUSA] Guidelines, 2010). It primarily refers to a network of expertise, intermediation and resources placed at the disposal of someone seeking answers in an online environment (Berube, 2003). It has brought about tremendous change in the concept of reference services in terms of information dissemination and user satisfaction. Various initiatives have already been taken to develop standards, guidelines and procedures for setting up successful digital reference systems. Virtual reference has emerged as a new powerful method of delivering reference and information service to a vast number of clientele distributed globally. It includes seamless access to global resources and the collection of knowledge for reference access, coupled with complementary access to information on the internet. It has brought about tremendous change in the concept of reference services in terms of information dissemination and user satisfaction. The seamless influence of Social Networking tools on virtual reference is quite evident and trend is fast shifting towards incorporating such tools in libraries at global level. These tools not only solve the problems of communicating in real time environment in all modes ranging from instant messaging to audio/visuals but also provide ample opportunities for libraries to retain their users. The present work thus discusses the concept of Virtual Reference Service and possible use of different Social Networking tools in present day Virtual Reference Systems for successfully addressing user queries.

Abstract:
Migration from the traditional to web-based library paradigm is usually accompanied by remodelling of many library core activities particularly those associated with user-centred services. In this capacity of the web-based service paradigm, many academic libraries have established networked environments within which many virtual-user communities are forming and growing. Understanding the virtual user's needs in these communities has become the first priority of networked libraries for designing, running and managing effective virtual reference services to meet the increasing expectations of the invisible users. To achieve this, the networked libraries strive to improve their quality of service by applying a wide range of such quality management approaches as quality function deployment (QFD) and LIBQUAL™. QFD initially stresses on driving continuous improvement of the user-oriented services towards end-user satisfaction. The paper attempts to incorporate the QFD to be integrated strategically in designing and managing e-information provision within networked library service environment. The UAE University Library is used as a case study, where the evidence-based librarianship (EBL) approach has been employed in three studies to identify user needs and acceptance of e-services. Based on these studies, the paper presents a model aimed at streamlining e-services for virtual users in ICT-rich learning environments.

Abstract:
O Serviço de Referência (SR), incorporando na sua organização, funcionamento e comunicação com o utilizador um conjunto de potencialidades proporcionadas pela tecnologia, assume um papel fundamental na luta contra a desigualdade e o analfabetismo digital, no fomento da literacia da informação e na criação de conhecimento. A percepção do valor e das fragilidades do SR nas bibliotecas públicas em Portugal levanta a questão sobre como contribuir para o seu desenvolvimento. A presente investigação, visando a construção de alicerces numa perspectiva de evolução, parte da análise de documentos orientadores internacionais da RUSA/ALA (Reference and User Services Association / American Library Association) e da IFLA (International Federation of Library Association) e da observação de características estruturais da Rede Nacional de Biblioteca Públicas (RNBP), para a concepção de soluções de desenvolvimento do SR a aplicar a esta realidade concreta. Seguindo um paradigma compreensivo indutivo, com uma orientação baseada na Grounded Theory, esta pesquisa privilegia o contexto da descoberta e a construção de uma teoria. No plano empírico cumpre uma complementaridade de técnicas qualitativas e quantitativas, com recurso a uma triangulação metodológica. O campo de análise abrange a totalidade das bibliotecas públicas portuguesas integradas na RNBP em Portugal. Visando aspectos funcionais e materiais, são analisados dados preexistentes e aplicadas técnicas de observação directa e inquérito por questionário. Visando aspectos sociais, são efectuadas seis entrevistas semi-estruturadas. Os resultados apontam para uma situação de estagnação das bibliotecas da RNBP e para um funcionamento não estruturado e informal do SR, na maioria dos casos em que se verifica a sua disponibilização. Fundamentada a necessidade de evolução, e do investimento que nele possa ser feito, é construído um modelo, seguindo uma estratégia por níveis, flexíveis e adaptáveis às necessidades e aos recursos de cada biblioteca, que visa o desenvolvimento incremental e congruente daquele serviço; Abstract: The Reference Service in public libraries in Portugal. Development model from international guidelines. Incorporating in its organization, procedures and communication with the users a set of tools brought by technology, Reference Service (RS) plays a key role in the struggle against inequality and digital illiteracy, promoting information literacy and creating knowledge. The perception of the value of RS and the weaknesses in public libraries in Portugal raise the question on how to contribute to its development. In order to build RS foundations on an evolutionary perspective, this research analyzes RUSA / ALA (Reference and User Services Association / American Library Association) and IFLA (International Federation of Library Association) international guidelines and the structural characteristics of the Portuguese National Public Library Network (RNBP), with the objective of creating a solution for the development of that service to be applied to this reality. Following an inductive comprehensive paradigm, with an orientation based on Grounded Theory, this research focuses on the context of discovery and the construction of a theory. Empirically it fulfils complementary qualitative and quantitative techniques, using a methodological triangulation. The field of analysis covers Portuguese public libraries integrating the RNBP. Aiming at functional and material aspects, direct observation techniques and a survey by questionnaire are applied. Targeting social aspects, six semistructured interviews are carried out. The results point to a situation of stagnation in the RNBP as well as the unstructured and informal performance of the SR, which justifies the need for evolution and investment. A model is constructed, following a strategy based on levels, flexible and adaptable to the needs and resources of each library, with the perspective of an incremental and consistent development of this service.

Desde o seu surgimento, a Internet, e nela a Web, têm se popularizado de maneira a tornar-se tecnologia essencial de informação e comunicação, tanto nos países desenvolvidos, quanto em países emergentes. Com o advento da Web Colaborativa, as bibliotecas acadêmicas no mundo todo têm enfrentado o desafio de continuamente repensar a maneira como seus serviços vêm sendo disponibilizados de forma a atingir seus usuários, em especial a geração dos nativos digitais. Nesse contexto de dinamicidade tecnológica surgiu a biblioteca denominada 2.0, que passou a oferecer Serviços de Referência Virtual (SRV) disponibilizando em seus sites, dentre outros serviços, a possibilidade de se comunicar com o bibliotecário através de email e posteriormente chats (ou mensagem instantânea) em tempo real. Este estudo objetivou primeiramente apresentar e delinear as características de um software gratuito de videoconferência e chat que usa tecnologia VoiP utilizado para referência em bibliotecas norte-americanas. Encontrou-se que, embora esse software tenha sido implantando em várias bibliotecas universitárias norte-americanas, com o tempo, essas decidiram por descontinuar o seu uso. Portanto, o foco do estudo se ampliou para a análise dos software para os quais essas bibliotecas migraram e as características dos seus sistemas. Analisa-se também as iniciativas de bibliotecas de universidades brasileiras que implantaram o SRV por meio de chat, os software que estão utilizando atualmente e os fatores considerados por essas instituições no momento da decisão pela implantação do sistema. A permissão para a tradução para a língua portuguesa do guia de Boas Práticas, Políticas e Procedimentos do QuestionPoint 24/7 foi obtida a fim de complementar esse estudo e nortear as bibliotecas brasileiras desejosas de disponibilizar o SRV via chat. A metodologia de pesquisa consistiu em um aporte teórico realizado a partir da literatura produzida nacional e internacionalmente sobre o tema, bem como pesquisa exploratória e observações participantes nos sites de bibliotecas universitárias brasileiras e norte-americanas que disponibilizam o SRV via chat. Este estudo concluiu que o SRV via chat traz benefícios à comunidade e coloca a biblioteca em consonância com as demandas tecnológicas de informação e comunicação sendo apropriado à realidade de bibliotecas acadêmicas brasileiras. Ainda, descobriu que algumas bibliotecas norte-americanas estão fazendo o uso de um software para oferecer o que chamam de Serviço de Referência Proativo.
Since its development, the Internet, and the Web in it, has gained popularity and become core technology of information and communication, both in developed countries and emerging countries. With the advent of Collaborative Web, academic libraries worldwide have faced the challenge of continually rethink the way their services is being made available to achieve its patrons, especially the generation of digital natives. In this context of technological dynamism, Library 2.0 arose, offering Virtual Reference Service (VRS), making available on their websites, among other services, the possibility to communicate with the librarian via email and then chat (or Instant Message) in real time. This study aimed primarily to present and outline the features of a free chat and video chat software that uses VoIP technology used for reference in U.S. libraries. It was found that although this software had been used by several U.S. academic libraries, with time, these institutions decided to discontinue its use. Therefore, the focus of the study was extended to the analysis of the software for which those libraries migrated and the features of their systems. The study also analyses the initiatives of Brazilian academic libraries that have implemented the SRV via chat, the software they are currently using and the factors considered by these institutions when deciding the implementation. Permission to translate QuestionPoint 24/7 Best Practices, Policies and Procedures into Portuguese was obtained in order to complement this study and guide the Brazilian libraries wishing to provide the VRS chat. The research methodology consisted of a theoretical contribution from the literature produced nationally and internationally on the topic, as well as exploratory research and participant observations on the Brazilian and American university libraries which offer the SRV chat on their website. This study concluded that VRS via chat brings benefits to the community and puts the library in line with the technological demands of information and communication therefore it is appropriate to the reality of Brazilian academic libraries. In addition, the investigation found out that some American libraries are making use of software to offer what is being called Proactive Reference Service.

Abstract:
This study reports an experiment that examines whether librarians provide equitable virtual reference services to diverse user groups. The relative absence of social cues in the virtual environment may mean greater equality of services though at the same time greater inequalities may arise as librarians can become less self-aware online. Findings indicate that the quality of service librarians provide to African Americans and Arabs is lower than the quality of service they provide to Caucasian, Hispanic, Asian, and Jewish students. This study adds to the knowledge of subjective bias in the virtual environment by specifying those that are discriminated against online, identifying the kinds of discriminatory actions of virtual reference librarians, and identifying the type of queries that more frequently result in unbiased service.

Los Centros de Información de la Universidad de Peruana de Ciencias Aplicadas (UPC) implementan el Servicio de referencia virtual, a través de la plataforma Question Point, en el año 2009, con el soporte tecnológico de OCLC (Online Computer Library Center) y ante la necesidad de los usuarios que demandaban un canal de comunicación online, que les permita realizar sus consultas académicas, referentes a los servicios que ofrecen los Centros de información. La implementación de este servicio ha permitido atender hasta la fecha 6534 consultas vía email (formulario web) y chat, lo que no solo ha servido para satisfacer las consultas de los usuarios sino también para formarlos en estrategias de búsquedas y en el uso correcto de los servicios físicos y digitales que ofrecemos a la comunidad universitaria. A partir del año 2011, se integra un Qwidget de chat del Question Point en el Aula Virtual de los alumnos, debido a que se identifica a esta última, como el ambiente virtual más utilizado por los alumnos, al consultar los materiales de enseñanza de sus cursos. Esta estrategia tiene como finalidad que los alumnos puedan encontrar en su principal medio de interacción virtual, una nueva alternativa de comunicación con los Centros de Información, para la resolución de sus consultas referentes a la búsqueda de fuentes de información bibliográfica así como también para solicitar orientación en el uso de los distintos servicios que se ofrecen. Esta estrategia ha dado como resultado que en el año 2013 el número de consultas vía chat se incremente en un 73% respecto al año 2011. Asimismo, cabe resaltar que en promedio el 59% de las consultas vía chat son realizadas desde el Qwidget insertado en el Aula Virtual. Finalmente, un dato resaltante es que el 74% de las consultas recibidas son a través del canal del chat, lo cual indica que existe una marcada tendencia de los usuarios al uso de estos servicios, por lo que se recomienda a otras áreas de la universidad, tomar esta experiencia como modelo para la atención de las consultas que reciben de sus usuarios.

Abstract:
The aim of this master’s thesis is to examine the virtual reference service Ask the Library [Bibblan svarar] from a postmodern perspective. Ask the Library is a Swedish online reference service that is run by the country’s public libraries. The postmodern theories of Jean-François Lyotard are used to study how information is managed and transmitted within the service. From this point-of-view three aspects of the reference service are studied; how the information is affected by the virtual environment, the librarian’s role within the service and finally how the content of the service is managed. The methods for extracting data are a blend of qualitative interviews and online observations. The data is then analyzed from a theoretical viewpoint. The result shows that there are several postmodern tendencies in Ask the Library. Namely the service shows a number of indications toward plurality. This can be related to Lyotard’s theory of the downfall of the grand narratives since postmodern theories celebrate the idea of plurality and diversity. Ask the Library is complex and dynamic in the sense that it adapts its services to the users. In addition to a multilingual service, Ask the Library also offers the users reference help in the form of social network sites like Facebook and Twitter. This makes the service more varied but also deeply complex. The reference service also emphasizes on the librarian’s individual competence and promotes personal knowledge and expertise. In Lyotard’s postmodern theories there is a rejection of absolute and objective truths and this falls in line with the subjectivity that the reference service celebrates. Ask the Library has two different agendas; providing qualitative reference service to the users and also promoting the librarians and their skills. The information, or content, in the service is still organized and under examination by the librarians. Critique of the sources is an important skill for a librarian within Ask the Library to have. These traditional ideas of objective truth are balanced with the new virtual environment that often promotes collective construction of information and knowledge. This study is a two years master’s thesis in the academic field library and information science.

Abstract:

In libraries around the world there are people asking librarians for research assistance. As technology has advanced and communication strategies have moved outside the physical library buildings, librarians now respond to reference queries online. This study analyzed two forms of virtual reference; instant messaging (IM) and log-in chat. The purpose of this study was to find out if there is any inherent difference between the way the patrons or the librarians used these two virtual services.

An exploratory research design focused on numerous aspects of virtual reference communication. During the spring terms of academic years 2011 and 2012 at a community college, 1,341 transcripts of IM and log-in chat sessions were recorded. Using a systematic sampling process, 320 transcripts were sampled and their content analyzed.

Findings indicate that a length of the transaction significantly affected the outcome of all transactions. Log-in chats were generally longer than IM chats and it was found that; they were more complicated, the librarians were more responsive and friendly, patrons were more satisfied and the librarian was generally able to conduct a reference interview more often. Additionally the findings indicated that both IM and log-in chat were very similar in three aspect; patron formality, completeness/accuracy of the librarians' answer and the reference interview adding/changing or clarifying the patrons question.

There were four major conclusions of this study: The log-in chat portal had longer online reference transactions and better overall outcomes; instant messaging portal queries, although similar in many aspects to log-in chat, were ultimately treated in a less formal manner by patrons; librarians gave reference interviews and complete/accurate answers equally in both platforms and there were similar overall success rates in both platforms.

Based on the findings in this study it is recommended that academic libraries serving a general population of students use both the IM and log-in chat portals on their library websites. Patrons appear to appears to be using each portal for different and equally important reasons. Further study of virtual communications practices is needed to enhance the findings of this study as more institutions expand their patron base beyond those who can physically meet with a reference librarian.

Abstract:
The advances in ICTs have decisively changed the library and learning environment. On the one hand, ICTs have enhanced the variety and accessibility to library collections and services to break the barriers of location and time. On the other, the e-Learning has emerged as an additional medium for imparting education in many disciplines to overcome the constraint of physical capacity associated with the traditional classroom methods. For a vast developing country like India, this provides an immense opportunity to provide even higher education to remote places besides extending the library services through networking. Thanks to the recent initiatives by the public and private institutions in this direction, a few web-based instruction courses are now running in the country. This paper reviews different aspects of e-Learning and emerging learning landscapes. It further presents the library scene and new opportunities for its participation in the e-Learning process. How these ICTs driven advances can contribute to the comprehensive learning process in India is highlighted.

Full text
Abstract:
With the frequent occurrence of epidemic diseases such as “SARS”, “H1N1”, “MERS”and“COVID19”, public health emergencies, which are characterized by large-scale, high risk, strong persistence and high risk, have become more and more obvious threats to the life and health of urban residents and put forward a huge test to the urban public service system. As the first city of COVID-19 human infection, the core of the epidemic spread and the worst-hit area, Wuhan is an ideal case study. Based on the analysis of the epidemic prevention and control actions in the first three months of the outbreak in Wuhan, this paper evaluates the vulnerability of the public service system and facilities in Wuhan. The results show that Wuhan is faced with many problems, such as the failure of community-level public service facilities, the imbalance of public service allocation in the central city, and the significant gap of graded service supply, when dealing with public health emergencies. Further studies found that due to the lack of dynamic early warning mechanism, the decoupling of public service construction from the urbanization process, the difficulty of service turnover and subsidence and other factors, the public service response was delayed. Based on these practical difficulties, this paper puts forward the construction path of the emergency response mechanism for the city level public service system, specifically including the following six key contents: (1) Improving the emergency plan path of the public service system; (2) Establishing the organizational structure of the emergency management system according to the administrative divisions; (3) Building a community-based mobilization system; (4) Establishing the regional joint defense and control interaction mechanism in public health emergencies; (5) Reserving appropriate strategic construction space; (6) Strengthening the emergency infrastructure construction. Finally, based on the path of emergency response mechanism, this paper proposes the corresponding city wide spatio-temporal prevention and control network strategy, so as to provide a reference for the realization of city health and order.

Full text
Abstract:
It is an important basis for optimizing land spatial patterns and guiding land spatial planning to clarify the ecological conditions of land space, arrange reasonably agricultural production and urban-rural construction space. The network formed by green infrastructures has important ecological significance in maintaining the migration of biological species and ensuring the continuity of the ecological process. Based on the concept of ecological priority and green development, this paper constructs a framework of the land space development suitability evaluation based on green infrastructure evaluation. From the perspective of ecosystem service value and ecological sensitivity, the evaluation factors are selected to make a comprehensive evaluation of green infrastructure. The evaluation results are the basis for the evaluation of the importance of ecological protection, the suitability of agricultural production, and the suitability of construction. At last, taking Harbin as an example, the evaluation framework is applied to preliminarily determine the red line of ecological protection and the scope of ecological space, agricultural space, and urban-rural construction space in 2015. It is expected to provide a reference basis for the compilation of land and space planning in Harbin.

Abstract:
Although 3D printing has attracted remarkable attention from both industry and academia society, still only a relatively small number of people have access to required 3D printers and know how to use them. One of the challenges is that how to fill the gap between the unbalanced supply of various 3D printing capabilities and the customized demands from geographically distributed customers. The integration of 3D printing into cloud manufacturing may promote the development of future smart networks of virtual 3D printing cloud, and allow a new service-oriented 3D printing business model to achieve mass customization. This paper presents a primary 3D printing cloud model and an advanced 3D printing cloud model, and analyzes the 3D printing service delivery paradigms in the models. Further, the paper proposes a 3D printing cloud platform architecture design to support the advanced model. The proposed advanced 3D printing cloud model as well as the architecture design can provide a reference for the development of various 3D printing clouds.

Full text
Abstract:
Under the background of the rapid urbanization, suburbs have become the forefront of urban living space. Compared with the dwellers in the city center, the daily behavior characteristics of suburban dwellers are more varied due to the commuting distance and employment opportunities. Thus, if the city governor only based on the socio-economic or population density index to allocate the public resources, it might result waste. In here, we attempt to discuss the approach to reduce this kind of waste through dynamic behavior perspectives. Based on the above, Shenyang (the provincial capital city which located in the Northeast of China) was selected as a sample. The research collected LBS (Location Based Service) big data of 24 hours for seven consecutive days. Based on ST-DBSCAN clustering algorithm, the movement trajectories and stop points of 818 suburban dwellers in southern suburbs were recognized. Then, the activity type of each stop point was identified with time-space threshold method, including working behavior, residential behavior, non-work behavior outside home. Afterwards, based on the time rhythm characteristics of working and residential behaviors，the dwellers were divided in four types of daily activity patterns: Normal-time-rhythm group, Early-time-restricted- rhythm group Late-time–restricted-rhythm group, Dual-time-restricted-rhythm group. Based on the classification, the spatio-temporal distribution of the daily space of the residents during the weekdays and weekends are measured, the methods of geo-visualization and analysis of variance are applied to compare the differences in the daily activity space of different groups. The result indicated that the time constraints indeed affect the spatio-temporal distribution of non-working behaviors outside home in different ways, which further affects the use of city and community functional space. The finding focus on the different demands of groups of different lifestyles, providing a certain reference for the facilities time management and optimization of public facilities configuration policy.

Abstract:
The diagnosis of soft faults in vapor compression cooling systems is a crucial activity, since malfunctions may provoke heavy degradation in plant performance and increase the power consumption for space cooling. Among the various Faults Detection and Diagnosis techniques developed over the last two decades, thermoeconomic diagnosis has been playing only a marginal role due to the difficulties encountered when applying the conventional thermoeconomic approaches to vapor compression refrigeration plants. In this paper a critical analysis on capabilities and limits of thermoeconomic diagnosis of refrigeration systems is proposed. The reference plant assumed for this study is a 116 kWc air-condensed rooftop systems charged with R407C as refrigerant. A reliable 1-D steady-state simulator is used to calculate thermodynamic and performance data in “off-design” operating conditions; since the simulator has no specific capabilities to simulate faulty systems, literature-derived results were used to adjust the input settings for each specific fault simulated. Among the most common faults in rooftop air conditioners, four different malfunctions are examined: fouling at condenser, fouling at evaporator, refrigerant undercharge (either due to leakage or erroneous charging during service) and extra-superheating along the suction line; the faults are imposed both individually and simultaneously. The thermoeconomic diagnosis is performed basing on the “fuel impact” approach; the need to split physical exergy into its thermal and mechanical fractions and the presence of dissipative components suggested us to formulate some methodological premises, discussed in detail in the paper. The results testify that the adopted conventional approach is not very reliable; although some faults are properly identified, in fact, false fault signals and erroneous causalization eventually resulted, due to the presence of system-level faults (i.e. faults not strictly associated with any specific plant component, like refrigerant undercharge), the subjective assumptions made as concerns the cost allocation of residues and some controversial aspects concerning the productive structure.
