The purpose of this paper is to develop a facade for seamlessly using locating services and enabling easy development of an application with indoor and outdoor location information without being aware of the difference of individual services. To achieve this purpose, in this paper, a unified locating service, called KULOCS (Kobe-University Unified LOCating Service), which horizontally integrates the heterogeneous locating services, is proposed.

By focusing on technology-independent elements [when], [where] and [who] in location queries, KULOCS integrates data and operations of the existing locating services. In the data integration, a method where the time representation, the locations and the namespace are consolidated by the Unix time, the location labels and the alias table, respectively, is proposed. Based on the possible combinations of the three elements, an application-neutral application programming interface (API) for the operation integration is derived.

Using KULOCS, various practical services are enabled. In addition, the experimental evaluation shows the practical feasibility by comparing cases with or without KULOCS. The result shows that KULOCS reduces the effort of application development, especially when the number of locating services becomes large.

KULOCS works as a seamless facade with the underlying locating services, the users and applications consume location information easily and efficiently, without knowing concrete services actually locating target objects.

There has been considerable discussion about the benefits of health and social care integration over the last decade but less research on the purpose and effectiveness of carer and user involvement in service changes and service evaluation. The paper aims to report the findings of a study of two learning disabilities services in Wales that undertook co-location in a children development centre.

The study investigated whether carers of children with learning disabilities had any knowledge of organisational changes that occurred as a result of co-locating services. The study used a mixed method approach. The authors conducted semi-structured interviews with all parental representatives on the service planning groups and then asked local staff to facilitate a survey to parents of children with learning disabilities in their area.

Carers in both locations were mainly unaware of any changes, unless they were personally involved in service changes through advocacy or parental support groups. Carer responses mainly reflected national debates, such as service cuts, rather than the local context. Whilst there was significant support for co-location in general, parental views differed considerably on the merits of service changes depending on the needs of their own child.

These results caution against assuming a simple pathway from parental views of local services to defining service needs to plan new services. The authors argue that parents lack sufficient knowledge of organisational changes to make an informed decision on whether these changes would bring about service improvements. Implications for research and professional practice are spelled out.

New resources and services are being added to the network daily. The number of prospective users of these resources is expanding rapidly, but problems arise when individuals attempt to identify, locate, and access networked information in today's dynamic environment. This paper describes Archie, an electronic indexing service for locating information that exists on the Internet. The author describes the Archie service in the context of the Resource Discovery Problem and discusses enhancements that are planned for Archie.

This study aims to understand elderly people and their family members’ perceptions and usage of a mobile personal safety service.

The study adopts both interviews and analysis of actual usage data to cross-validate the findings. Four family groups and 11 subjects participated in the study.

Elderly people are willing to learn to use the mobile safety service, and some elderly people explore more features than their younger family members. Family support facilitates their learning. Elderly people feel psychologically secure when using the mobile safety service. Privacy concerns are mitigated because they consider location sharing is necessary for the service.

The current sample is small, as it involves collection of both interview data and actual usage data. Considering the emergency of the mobile personal safety service, the study is exploratory.

The findings suggest that elderly people are willing to learn and use technology such as the mobile safety service, which is relevant to their daily lives. Designers may think about how to highlight the relevancy aspect of technologies in elderly peoples’ lives.

This study is one of the earliest studies about elderly people’s usage of mobile safety service. This study reveals that elderly people are willing to learn to use the mobile safety service and explore its features. Technical support from family members and relevancy of the service in their daily lives may encourage them to use the technology.

This exploratory study, a Ph.D. dissertation completed at the University of Western Ontario in 2013, examines the materially embedded relations of power between library users and staff in public libraries and how building design regulates spatial behavior according to organizational objectives. It considers three public library buildings as organization spaces (Dale & Burrell, 2008) and determines the extent to which their spatial organizations reproduce the relations of power between the library and its public that originated with the modern public library building type ca. 1900. Adopting a multicase study design, I conducted site visits to three, purposefully selected public library buildings of similar size but various ages. Site visits included: blueprint analysis; organizational document analysis; in-depth, semi-structured interviews with library users and library staff; cognitive mapping exercises; observations; and photography.

Despite newer approaches to designing public library buildings, the use of newer information technologies, and the emergence of newer paradigms of library service delivery (e.g., the user-centered model), findings strongly suggest that the library as an organization still relies on many of the same socio-spatial models of control as it did one century ago when public library design first became standardized. The three public libraries examined show spatial organizations that were designed primarily with the librarian, library materials, and library operations in mind far more than the library user or the user’s many needs. This not only calls into question the public library’s progressiveness over the last century but also hints at its ability to survive in the new century.

The purpose of this paper is to characterise a number of current and future computing environments and summarises their resource discovery requirements. It then seeks to analyse, with respect to the requirements of each environment, several established service discovery protocols and some newer protocols that are still in the research domain. In addition, the key features of a new resource discovery protocol that has been developed to operate with heterogeneous computing environments are described.

A comprehensive literature survey was undertaken, highlighting the shortcomings of existing resource discovery protocols with respect to large pervasive computing environments. Given the identified gaps in existing protocols, an alternative protocol is suggested.

The main findings of this paper relate to the identified shortcomings of existing resource discovery protocols. It was also found that a hybrid resource discovery protocol capable of spanning dynamic, mobile computing environments and more stable ones was able to overcome many of the challenges presented by large‐scale pervasive computing environments.

This paper presents comprehensive literature survey of the state‐of‐the‐art in resource discovery protocols, pointing out some of the problems that are not solved. The paper describes the design of an alternative protocol, and presents an evaluation of it. The pervasive computing research community can draw upon the survey and evaluation to guide the design of future resource discovery protocols for the increasingly dynamic world in which we live.

The management of autonomous, heterogeneous network resources and services provides new challenges which libraries are now addressing. This paper outlines an approach based on the construction of broker services which mediate access to resources. It outlines a framework – the MODELS Information Architecture – for thinking about the components of broker services and their logical arrangement. It describes several development projects and services which show how brokers are developing. It uses examples drawn from the serials environment to describe some of the issues. Technologists understand that they must build more stable and unobtrusive media. They must establish more coherent contexts into which the technology may disappear.

To analyze the direct effect of perceived value dimensions (monetary, convenience, social, emotional, conditional and epistemic value) on attitudinal and behavioral components of loyalty: commitment and behavioral intentions to use location‐based mobile services.

An online survey for users of a mobile location‐based directory service “Where is the nearest?”

The behavioral intentions were most influenced by conditional value; the context, in which the service is used, followed closely by commitment and to some extent monetary value. Commitment can be enhanced through building emotional value and conditional value by focusing on offering fun service experiences in the right context. The influence of social and epistemic value was not significant.

Further research is encouraged on the relative importance of the value dimensions' influence on loyalty in global markets.

The minor influence of monetary value as well as the high influence of conditional value implies that the one‐dimensional value measures are not applicable in a mobile context where decisions are often made spontaneously and based on situational needs. Effective marketing strategies need to take into account the contextual use and emphasize either convenience or emotional value.

The paper introduces new context relevant concepts and develops a multidimensional perceived value and loyalty model. Results give practical implications on how to increase awareness of location‐based services (LBS) in a way that gives a realistic picture of how LBS create value for customers.

Family Justice Centers, or “one-stop shops” that enable domestic violence victims to access a range of services at one location, are becoming increasingly common. However, there is a limited body of research examining the outcomes and planning processes of these Centers. The early phases of planning Centers are critical to their initial and ongoing success. The purpose of this paper is to discuss these issues.

In total, 15 stakeholders in a community in the early phases of planning a Center were interviewed.

Content analysis procedures were used to identify themes related to participants’ ideas about what the Family Justice Center should look like (e.g. services to include and perceived benefits and challenges for the Center), the steps required for planning it (e.g. identifying the purpose of the Center, getting key people involved, and building collaborations), and desired technologies.

This paper is the first known research effort to examine the early phases of development in constructing a Family Justice Center.

The main goal of this paper is to study the cloud service discovery mechanisms. In this paper, the discovery mechanisms are ranked in three major classes: centralized, decentralized, and hybrid. Moreover, in this classification, the peer-to-peer (P2P) and agent-based mechanisms are considered the parts of the decentralized mechanism. This paper investigates the main improvements in these three main categories and outlines new challenges. Moreover, the other goals are analyzing the current challenges in a range of problem areas related to cloud discovery mechanisms and summarizing the discussed service discovery techniques.

Systematic literature review (SLR) is utilized to detect, evaluate and combine findings from related investigations. The SLR consists of two key stages in this paper: question formalization and article selection processes. The latter includes three steps: automated search, article selection and analysis of publication. These investigations solved one or more service discovery research issues and performed a general study of an experimental examination on cloud service discovery challenges.

In this paper, a parametric comparison of the discovery methods is suggested. It also demonstrates future directions and research opportunities for cloud service discovery. This survey will help researchers understand the advances made in cloud service discovery directly. Furthermore, the performed evaluations have shown that some criteria such as security, robustness and reliability attained low attention in the previous studies. The results also showed that the number of cloud service discovery–related articles rose significantly in 2020.

This research aimed to be comprehensive, but there were some constraints. The limitations that the authors have faced in this article are divided into three parts. Articles in which service discovery was not the primary purpose and their title did not include the related terms to cloud service discovery were also removed. Also, non-English articles and conference papers have not been reviewed. Besides, the local articles have not been considered.

One of the most critical cloud computing topics is finding appropriate services depending on consumer demand in real-world scenarios. Effective discovery, finding and selection of relevant services are necessary to gain the best efficiency. Practitioners can thus readily understand various perspectives relevant to cloud service discovery mechanisms. This paper's findings will also benefit academicians and provide insights into future study areas in this field. Besides, the drawbacks and benefits of the analyzed mechanisms have been analyzed, which causes the development of more efficient and practical mechanisms for service discovery in cloud environments in the future.

This survey will assist academics and practical professionals directly in their understanding of developments in service discovery mechanisms. It is a unique paper investigating the current and important cloud discovery methods based on a logical categorization to the best of the authors’ knowledge.
