pp. 135-159

The goal of this chapter is to discuss development trends of information systems. The chapter begins by discussing a framework known as the semantic ladder. This framework provides an overview and shows relations between data, information, concepts, knowledge, and wisdom. The chapter then discusses three domains of scientific activity: data science, knowledge science, and wisdom science. Next, the chapter considers how we can move from a science of information to a science focused on informing. Ways of measuring the quality of information is then considered. The chapter concludes by examining the latest trends in designing information systems during the past century.

Decision support systems (DSS) are interactive computer-based systems that provide information, modeling, and manipulation of data. DSS are clearly knowledge-based information systems to capture, Processing and analysis of information affecting or aims to influence the decision making process, performed by people in scope professional job appointed by a user. Hence, this study describes briefly the key concepts of decision support systems such as perceived factors with a focus on quality  of information systems and quality of information variables, behavioral intention of using DSS, and actual DSS use by adopting and extending the technology acceptance model (TAM) of Davis (1989); and Davis, Bagozzi and Warshaw (1989).There are two main goals, which stimulate the study. The first goal is to combine Perceived DSS factors and behavioral intention to use DSS from both the social perspective and a technology perspective with regard to actual DSS usage, and an experimental test of relations provide strategic locations to organizations and providing indicators that should help them manage their DSS effectiveness. Managers face the dilemma in choosing and focusing on most important factors which contributing to the positive behavioral intention of use DSS by the decision makers, which, in turn, could contribute positively in the actual DSS usage by them and other users to effectively solve organizational problems. Hence, this study presents a model which should provide the useful tool for top management in the higher education institutions- in particular-to understand the factors that determine using behaviors for designing proactive interventions and to motivate the acceptance of TAM in order to use the DSS in a way that contributes to the higher education decision-making plan and IT policy.To accomplish or attain the above mentioned objectives, the researcher developed a research instrument (questionnaire) and distributed it amongst the higher education institutions in Jordan to collect data in order to empirically study hypothesis testing (related to the objectives of study). 341 questionnaires were returned from the study respondents. Data were analyzed by utilizing both SPSS (conducted descriptive analysis) and AMOS (conducting structural equation modelling).Findings of the study indicate that some hypotheses were supported while the others were not. Contributions of the study were presented. In addition, the researcher presented some recommendations. Finally, this study has identified opportunities for further study which has progressed greatly advanced understanding constantly of DSS usage, that can help formulate powerful strategies Involving differentiation between DSS perceived factors.

Systems developers and IT project managers who apply agile methods for developing information systems (IS) subscribe to a set of values and principles. This adherence to a set of values and principles, along with a passion or fervor surrounding the agile philosophy, made us question whether the adoption of agile methodologies has an effect on information systems built, and in particular, the quality of the IS developed. In this paper we construct a conceptual model, conduct a survey of software developers, and analyze our results, which support our hypotheses about the importance of the strategic selection of a development methodology. We conclude that practicing project managers should consider the decision to use certain methodologies as part of the strategic process.

Abstract. Thirty-six borehole temperature–depth profiles were analysed to reconstruct the ground surface temperature history (GSTH) of eastern Tasmania for the past 5 centuries. We used the singular value decomposition method to invert borehole temperatures to produce temperature histories. The quality of borehole data was classified as high or low based on model misfit. The quality of the borehole data was not dependent on topography or land use. Analysis reveals that three to five high-quality borehole temperature–depth profiles were adequate to reconstruct robust paleotemperature records from any area. Average GSTH reconstructed from Tasmanian boreholes shows temperature increases about 1.2 ± 0.2 °C during the past 5 centuries. Reconstructed temperatures were consistent with meteorological records and other proxy records from Tasmania during their period of overlap. Temperature changes were greatest around the north-east coast and decreased towards the centre of Tasmania. The extension of the East Australian Current (EAC) further south and its strengthening around the north-east coast of Tasmania over the past century was considered a prime driver of warmer temperatures observed in north-east Tasmania.

This paper juxtaposes two key themes: the concept of citizenship and ideas on urban renewal over the past century. The aim is to explore the interaction of cultural changes and the physical environment of cities. The concept of citizenship represents a cultural response to social change which itself has changed dramatically over the past century. Urban renewal has taken many forms. Yet behind all the growing technical expertise in dealing with the physical environment, there are specific social responses to the city which legitimize action. By looking at citizenship and urban renewal together, it is possible to establish a perspective on how the urban environment has been manipulated over the past century, often in ways which have barely interfaced with the social demands of many sections of the community.

BackgroundTranscatheter aortic-valve implantation (TAVI) has become an essential alternative to surgical aortic-valve replacement in the treatment of symptomatic severe aortic stenosis, and this procedure requires technical expertise. The aim of this study was to identify prospective studies on TAVI from the past 10 years, and then to analyze the quality of information reported about the learning curve.Materials and methodsA systematic review of articles published between 2007 and 2017 was performed using PubMed and the EMBASE database. Prospective studies regarding TAVI were included. The quality of information reported about the learning curve was evaluated using the following criteria: mention of the learning curve, the description of a roll-in phase, the involvement of a proctor, and the number of patients suggested to maintain skills.ResultsA total of sixty-eight studies met the selection criteria and were suitable for analysis. The learning curve was addressed in approximately half of the articles (n = 37, 54 percent). However, the roll-in period was mentioned by only eight studies (12 percent) and with very few details. Furthermore, a proctorship was disclosed in three articles (4 percent) whereas twenty-five studies (37 percent) included authors that were proctors for manufacturers of TAVI.ConclusionMany prospective studies on TAVI over the past 10 years mention learning curves as a core component of successful TAVI procedures. However, the quality of information reported about the learning curve is relatively poor, and uniform guidance on how to properly assess the learning curve is still missing.

<span>Over the past six years scholars have found the Internet to be a source of quick information. While the quality of information on the Internet may be questionable, nonetheless, sources of online studies are beginning to merge with library-based research. This article discusses the history of the Internet; concerns of using the Internet as a source, the importance of citing sources and how to cite electronic sources.</span>
