Personal ICT Ensembles and Ubiquitous Information Systems Environments: Key Issues and Research Implications

Personal information and communication technologies (ICTs) have become commonplace. Today many people own, or have access to, a range of different computing and communication devices, information technologies, and services, which they incorporate into their everyday routines. Increasingly, these technologies impact the way that individuals work, socialize, and play. Workers are bringing their personal ICTs to the office, and organizations are tailoring their computing environments toward ubiquitous integration with personal ICTs. These developments are opening up new ways of working, but they also create new challenges for organizations in accommodating this “nonaffiliated” use as part of their information systems environments. In this article we propose a framework for analyzing the composition and impact of personal ICT ensembles. The framework is positioned as pre-theory that invites further development and empirical testing. We illustrate how the proposed framework could be applied to consider personal ICT use across the work/home context. Several implications stemming from the notion of a personal ICT ensemble are highlighted, including practical considerations for nonaffiliated use in organizations. We conclude with suggestions for further development of the proposed framework.

Structural equation modeling for evaluating the user perceptions of E-learning effectiveness in higher education

A crucial prerequisite for sustainable e-learning is the understanding of learners’ preferences for various pedagogical strategies, technologies, and the management of learning resources. This paper presents an empirical study aiming to empirically test the theoretical (pedagogies, technologies and management) (PTM) model on the preference of learners and on the perceived impact of the effectiveness of e-learning. This study uses structural equation modelling (SEM) to identify the critical dimensions in the PTM model for augmenting the effectiveness of e-learning. This leads to the development of a PTM model with the path coefficients showing weak to strong relationships ranging from 0.15 to 0.42 with acceptable significance levels. The results support the hypothesis that management, technology, resources and metadata ontology dimensions affect the effectiveness of elearning both directly and indirectly through enhancing the management effectiveness of learning resources. However, the result does not support positive influence of pedagogical strategy per se on e-learning effectiveness. The implications of this study indicate the criticality of effective management of learning resources to enhance e-learning effectiveness.

Geographic information systems and coastal planning in Australia

The objective of this paper is to demonstrate the ability of visualization and simulation techniques to aid and simulate current and future directions in coastal planning. The process of visualization will interrogate the coastal cities of Portland, Apollo Bay, Anglesea and Hobsons Bay in south-eastern Australian coastal seaboard through a progression of projections and simulated forecasts from 2014 to 2050 to see if a process(s) or methodology could help in planning the future growth of coastal settlements. The analysis uses Geographic Information Systems (GIS) associated with planning application software.

The effects of perceived organizational support, perceived supervisor support and intra‐organizational network resources on turnover intentions: A study of Chinese employees in multinational enterprises

Purpose: The purpose of this study is to investigate the impact of perceived organizational support (POS), perceived supervisor support (PSS) and intra-organizational network resources on the turnover intentions of the Chinese employees of multinational enterprises. Design/methodology/approach: The study utilized structured equation modeling to analyze survey data from 437 Chinese employees of five multinational enterprises operating in the Chinese service sector. Findings: The study found that POS was positively related to affective organizational commitment, which in turn was negatively related to turnover intentions. A direct relationship was revealed between PSS and turnover intentions, as well as a mediated relationship through POS. In contrast, the relationship between intra-organizational network resources and turnover intentions was fully mediated through POS. Research limitations/implications: The cross sectional design is a limitation of the study. Another limitation regards the generalisability of the findings outside the specific research context. Future research should be extended to different geographical and organizational settings. Practical implications: In order to promote employee retention, multinational enterprises operating in China could start by carefully targeting visible support on offer to their employees. Improving supervisor support is a relatively inexpensive and practical measure compared to the costly alternatives such as improving employee compensation, training and career development. Organizations should also consider improving co-worker support schemes in the workplace which enable individuals to build up their network resources. Originality/value: The study provided evidence for both a direct relationship between PSS and turnover intentions and a mediated one via POS, confirming the generalisability of previous findings to the Chinese context. In addition it made an original contribution by establishing that POS fully, rather than partially mediated the relationship between intra-organizational network resources and turnover intentions. This suggests that Chinese employees attribute instrumental and expressive support from others in the organization as coming from the organization itself.

Water for life : the impact of the privatization of water services on child mortality

While most countries are committed to increasing access to safe water and thereby reducing child mortality, there is little consensus on how to actually improve water services. One important proposal under discussion is whether to privatize water provision. In the 1990s Argentina embarked on one of the largest privatization campaigns in the world including the privatization of local water companies covering approximately 30 percent of the country’s municipalities. Using the varia tion in ownership of water provision across time and space generated by the privatization process, we find that child mortality fell 8 percent in the areas that privatized their water services; and that the effect was largest (26 percent) in the poorest areas. We check the robustness of these estimates using cause specific mortality. While privatization is associated with significant reductions in deaths from infectious and parasitic diseases, it is uncorrelated with deaths from causes unrelated to water conditions.

Water resources management: crisis vs. success: success factors for water management through the examples of São Paulo and Paris

This dissertation aims at giving new insights for governments in understanding efficient water management models, especially in the case of the water crisis in Sao Paulo. Also, other actors dealing with water issues, such as multinational companies, could have new tools to improve efficiency in this field.
