Abstract:
Abstract This book chapter approaches the linkage between natural landscapes and human health through the lens of two guiding questions, the first considering the various ways nature benefits human health from both historic and contemporary perspectives, and the second considering the mechanisms through which this relationship occurs. In doing so, we consider the ways societies and cultures have mediated our relationship with the natural world over time, and the ways human health and planetary health are intertwined. It also examines these influences by providing an overview of what is currently known about specific variables, such as physical activity in natural landscapes, as well as discussing some of the past and current theories that seek to explain how these connections actually work. The book provides a bridge between what we do (individually and collectively) in natural settings and how those actions impact our health and our relationships with the natural world. The hope is that the information presented here empowers students and professionals to learn more and to be part of the rich dialogue occurring in many disciplines to help find ways to increase well-being for all people. The aim is for the readers to think critically about research and be able to analyse and evaluate the results. The bottom line, based on the undertaking of this book and the experience of the authors, is that nature has been and continues to be essential and incredibly positive for human life, and that mutualistic and reciprocal connections with nature will positively influence human development, health, and wellbeing.

Abstract:
This chapter explores situations in which the investigation produces several measured variables. As the ability to measure and record multiple variables with greater ease and accuracy continues to increase, we are being faced with very large data sets from which we wish to draw out hidden information. A general type of approach is to investigate whether different groups of variables provide related information and then whether it is possible to represent the actions of many variables with a small number of composite variables. The chapter then develops techniques of data reduction through principal component analysis, and data modelling through cluster analysis and multiple regression. It also takes the example of questionnaire data, which could also represent multiple experimental measurements, and identifies a wide range of possible analytical techniques, together with specific references to analyses developed previously.

Abstract:
The use of information technology (IT) in healthcare to improve outcomes is now a global phenomenon. If effectively implemented and efficiently leveraged, these technologies will greatly lower healthcare costs, improve safety, and elevate the quality of health. Nevertheless, health IT implementation and adoption continues to meet challenges. Reports show that physicians, nurses, and other healthcare professionals continue to resist health IT. Researchers have proposed models to explain this notion, and till date, there still is a lack of an overarching paradigm to view the concept. Resistance is a complex phenomenon that defies simple explanation and analysis. It requires well-accepted theories or paradigms encompassing the full range of variables associated with it. Understanding and mitigating user resistance is a great step toward improving sector-wide adoption. In this chapter, the authors survey extant theories of resistance and provide a paradigmatic lens for leveraging this knowledge to practical solutions in health IT adoption.

This chapter continues the path through the ISSP framework by considering the IT needs of government entities. The chapter discusses the evolution of eGovernment and mGovernment and presents research findings regarding the website evaluation of 40 countries using the Inland Revenue and Social Security governmental websites as the research basis. The website evaluation utilized an instrument developed by Cumbrowski that consists of eight dimensions. The research also examined the relationship between these website ratings and other variables extracted from reports provided by the International Telecommunication Union, World Economic Forum, and United Nations Development Programme. The chapter also examines the trends that are at the forefront of IT developments. The chapter concludes by applying various models to show how a government entity may determine its IT needs. The above are discussed in the context of how to improve public service delivery in the digital era, with numerous examples to support this discussion.

Full text
Abstract:
Recent advances in technology have led to the rapid development of electronic monitoring in the workplace (Chen &amp; Ross, 2007). Electronic monitoring is widely used in many industries, and there is no doubt that the size of the workforce subjected to it continues to grow (American Management Association, 2005; D’Urso, 2006). It is used by organizations due to its potential to optimize supervision and control processes, protect company assets, safeguard property information, and avoid costly litigation (Case &amp; Young, 2002; Friedman &amp; Reed, 2007). Electronic monitoring can become a central organizational tool for human resource management as well. It can have a profound impact on several HR functions. For example, an electronic monitoring system may be used as a source of data for performance management and performance evaluation and provide the basis for promotion, training, and development decisions (Wells, Moornan, &amp; Werner, 2007). Due to these capabilities, electronic monitoring affects an array of work-related attitudes and behaviors of employees and management (Stanton, 2000b). Existing research is focusing on identifying the ways to make electronic monitoring acceptable to all stakeholders, by elucidating electronic monitoring designs that help maintain the motivation and well-being of individuals. However, we are only beginning to address the issue of the effects of organizational culture and human resource strategy on the role of electronic monitoring and its effectiveness within specific organizational contexts (Chen &amp; Ross, 2005). These contextual factors may determine the role that electronic monitoring plays in managing human resources, from being one of the technology-enhanced human resource management practices devolved to line managers, to being a central part of the overall human resource strategy that supports various HR functions within an organization. The purpose of this article is to present a model of electronic monitoring effectiveness that combines the major electronic monitoring characteristics, their individual and organizational outcomes, and contextual variables that affect electronic monitoring acceptance and use.

Abstract Chapter 2 introduces our new measure of repressive spells which we defined as the duration of time government behavior existed above a certain threshold (i.e., a particular level of severity and size of the targeted population). When repression moves above this threshold, a spell begins. As long as repressive action stays above this level, it continues. Once repression falls below the designated level, the spell terminates. And, if, after having gone through a spell already, repressive behavior once again rises above the designated threshold, it is said to recur. Throughout the chapter we provide overviews of what the specific spell component look life. Chapter 2 also provides information about the diverse variables/policies that are employed in the world to reduce/stop repression and examined in empirical models.

This chapter describes balanced leadership theory. It starts by discussing the need for theories for good practical work. A positioning follows, which locates balanced leadership as a middle-range theory between substantive and grand theories. The chapter continues with some of the required information to make sense of the theory. This includes the philosophical stance, which is critical realism, and the theoretical lens, which is realist social theory and its morphogenetic cycle. A detailed description of the theory follows. This description addresses the theory’s constituting variables (the what), the macro- and micro-processes that explain the flow of activities (the how), the internal functioning and its relation to contingency theory (the why), and finally, the limitations and areas of application where the theory holds (the where/when/who).

Abstract:
The converging global environment has given rise to a social-constructivist approach to new literacy pedagogical and learning practices. Emergent digital and social spaces have created new literacy or multiliteracies. Support for multiliteracies is an inherently social construct which encapsulates human capital and Information Communications Technology (ICT), including technical and administrative infrastructure, policy and school culture, and teacher training and collaborative support. Several variables intervene in the pedagogical landscape in support of new literacy development in adolescent learners. Students become both producers and transmitters of multiliteracies through transformed practice and by forming social and professional identities, facilitated through authentic learning experiences. ICT is both a literacy as well as the media which support 21st century new literacy development. As socio-economic factors determine the availability and use of technology in the classroom, the hegemonic use of print and the inability to access “digital geographies” creates a digital divide. As literacy pedagogy continues to unfold, creative instruction must be employed in ensuring the development of multiliteracies through providing scaffolding, critical framing, and authentic learning experiences for students and teachers alike. This is explored in this chapter.

Abstract:
As the advance of Internet technology continues, various applications, services, and business models are emerging in the market. The online video sharing website is the hottest application nowadays; thus it is important to understand the key factors influencing user’s behavior on these websites. In this chapter, the authors propose a conceptual model which is based on the integrated model of user satisfaction and technology acceptance developed by Wixom and Todd (2005). To comprehend the user’s behavior intention toward using the website, the authors also add the potential factors about community which influence user’s behavior on video sharing websites. The results indicate that community satisfaction, content satisfaction, and system satisfaction all have significant positive impact on usefulness and ease of use, and that community satisfaction has a much higher impact than the other two types of satisfaction. This finding reveals an important attribute of video sharing websites, namely, the users of the website care most about the entire website community. Indeed, reliable system operations and useful, interactive content are two factors influencing the community satisfaction. For designers who want to set up a video sharing website, this research provides more comprehensive information on how to invest the limited resources on the critical variables in order to maximize the service value.

The number of hits to web pages continues to grow. The web has become one of the most popular platforms for disseminating and retrieving information. Consequently, many website operators are encouraged to analyze the use of their sites in order to improve their response to the expectations of internet users. However, the way a website is visited can change depending on a variety of factors. Usage models must therefore be continuously updated in order to accurately reflect visitor behavior. This remains difficult when the time dimension is neglected or simply introduced as an additional numeric attribute in the description of the data. Data mining is defined as the application of data analysis and discovery algorithms on large databases with the goal of discovering non-trivial models. Several algorithms have been proposed in order to formalize the new models discovered, to build more efficient models, to process new types of data, and to measure the differences between the data sets. However, the most traditional algorithms of data mining assume that the models are static and do not take into account the possible evolution of these models over time. These considerations have motivated significant efforts in the analysis of temporal data as well as the adaptation of static data mining methods to data that evolves over time. The review of the main aspects of data mining dealt with in this thesis constitutes the body of this chapter, followed by a state of the art of current work in this field as well as a discussion of the major issues that exist there. Interest in temporal databases has increased considerably in recent years, for example in the fields of finance, telecommunications, surveillance, etc. A growing number of prototypes and systems are being implemented to take into account the time dimension of data explicitly, for example to study the variability over time of analysis results. To model an application, it is necessary to choose a common language, precise and known by all members of a team. UML (unified modeling language, in English, or unified modeling language, in French) is an object-oriented modeling language standardized by the OMG. This chapter aims to present the modeling with the diagrams of packages and classes built using UML. This chapter presents the conceptual model of the data, and finally, the authors specify the SQL queries used for the extraction of descriptive statistical variables of the navigations from a warehouse containing the preprocessed usage data.

Abstract:
In this paper, a design-stage failure identification framework is proposed using a modeling and simulation approach based on Dimensional Analysis and qualitative physics. The proposed framework is intended to provide a new approach to model the behavior in the Functional-Failure Identification and Propagation (FFIP) framework, which estimates potential faults and their propagation paths under critical event scenarios. The initial FFIP framework is based on combining hierarchical system models of functionality and configuration, with behavioral simulation and qualitative reasoning. This paper p

Abstract:
In this paper reliability based design optimization by using radial basis function networks (RBFN) as surrogate models is presented. The RBFN are treated as regression models. By taking the center points equal to the sampling points an interpolation is obtained. The bias of the network is taken to be known a priori or posteriori. In the latter case, the well-known orthogonality constraint between the weights of the RBFN and the polynomial basis functions of the bias is adopted. The optimization is performed by using a first order reliability method (FORM)-based sequential linear programming (S
