Model Structures

The concept of active structural control as a means of structural protection against seismic loads, developed over the last 20 years, has received considerable attention in recent years. It has now reached the stage where active systems have been installed in full-scale structures. It is the purpose of this paper to provide an overview of this development with special emphasis placed on laboratory experiments using model structures and on full-scale implementation of some active control systems. Included in this paper is a report on the formation of a U.S. Panel on Structural Control Research and some discussion on possible future research directions in this exciting research area.

Future Research Directions

Thermally assisted machining (TAM) involves the use of a heating source to elevate the workpiece temperature at the cutting zone to facilitate the material removal process. TAM has evolved over the years with the emergence of new heating sources and the need to machine newly developed hard and brittle materials. In recent years, the main activities in this research area have been focused on laser assisted machining (LAM) at both the macro and micro scale, largely because of focused and controlled delivery of energy that can be achieved with a laser. This paper attempts to provide an overview of research in the general area of TAM, with an emphasis on LAM at the macro scale. Both experimental and theoretical/numerical work will be presented in this review. The challenges and progresses made so far will be detailed. And finally, future research directions in this area will be discussed.

Purpose The last decades have witnessed an increased interest in urban logistics originating from both the research and the practitioners’ communities. Sustainable freight transports today are on the political, social and technological agenda of many actors operating in urban contexts. Due to the extent of the covered areas and the continuous progress in many fields, the resulting body of research on urban logistics appears quite fragmented. From an engineering management perspective, the purpose of this paper is to present a systematic literature review (SLR) that aims to consolidate the knowledge on urban logistics, analyse the development of the discipline, and provide future research directions. Design/methodology/approach The paper discusses the main evidence emerging from a SLR on urban logistics. The corpus resulting from the SLR has been used to perform a citation network analysis and a main path analysis that together underpin the identification of the most investigated topics and methodologies in the field. Findings Through the analysis of a corpus of 104 articles, the most important research contributions on urban logistics that represent the structural backbone in the development of the research over time in the field are detected. Based on these findings, this work identifies and discusses three areas of potential interest for future research. Originality/value This paper presents an SLR related to a research area in which the literature is extremely fragmented. The results provide insights about the research path, current trends and future research directions in the field of urban logistics.

<p>This study aims to systematically synthesize more than 20 years of human resource outsourcing (HRO) studies in a way that is meaningful, concise and, useful to HRO researchers and practitioners. Using<b> </b>grounded coding technique blended with integrative literature review, empirical papers published from 1997 to 2018 are examined. This is the first HRO literature review using such techniques to answer three key research questions: What has the existing empirical academic literature revealed about the determinants of HRO decisions and outcomes? What are the key issues emerged from the literature? What are the gaps in knowledge which warrant future HRO research? Other than providing a comprehensive insight into an emerging research area, this review also contributes to laying an important foundation for the initial descriptive HRO theory development. 36 dependent variables and 99 independent variables over 449 relationships were coded.</p>

There has been a rapid growth in the research concerning mobile phones and the delivery of the learning experience in developing countries in recent years. The aim of this chapter is to improve understanding of this expanding research area and in so doing consider the potential for mobile phone applications for the delivery of educational services for the poor. The current state of knowledge is assessed by reviewing the existing research articles drawn from both peer-reviewed academic journals and non-peer reviewed studies and other practitioner-orientated sources. Issues relating to educational needs and the measurement of impacts have been comparatively neglected, whilst application design and adoption have received greater attention. Emphasis tends to be on devices and new ways to deliver services, but ignores the broader context of educational services for the poor and tends to be technology-led (Duncombe, 2006). In order to correct this imbalance in research, the paper identifies key points relating to concepts, methodologies, issues addressed and evidence presented and provides pointers to future research directions.

Information Seeking Behaviors

The emergence of rapidly developing Information Technologies, particularly the Internet and digital systems, provide people access to an overwhelming abundance of online resources. This, in turn, makes their information seeking process even more challenging. As an important research area in the field of information science and human computer interaction, human information seeking behavior has been researched for decades. In this entry, the authors focus on human information seeking behaviors in terms of their definition, the interactive, cognitive, contextual, and task aspects, and the intellectual knowledge and history. Since information seeking behaviors are a facet of the relatively new field of cyber behaviors, the chapter also discusses cyber behaviors in information seeking and the future research directions.

Digital image watermarking is an attractive research area since it protects the multimedia data from unauthorized access. For designing an efficient and robust digital image watermarking system, the trade-off among imperceptibility, robustness, capacity, and security must be maintained. Various studies regarding this concern have been performed to ensure these requirements by hybridizing different domains, such as spatial and transform domains. In this paper, we have presented an analytical study of the existing hybrid digital image watermarking methods. At first, we have given a standard framework for designing a hybrid method that ensures the basic design requirements of watermarking for various applications. After a brief literature review, we compared and analyzed the complexity of several existing hybrid methods in a tabular form. The limitations and applications of these methods are also highlighted. Finally, we summarized the challenges of the existing methods and concluded the study by giving future research directions.
