Senior managers’ perception on green information systems (IS) adoption and environmental performance: Results from a field survey

Based on a Belief-Action-Outcome framework, we produced a model that shows senior managers’ perception of both the antecedents to and the consequences of Green IS adoption by a firm. This conceptual model and its associated hypotheses were empirically tested using a dataset generated from a survey of 405 organizations. The results suggest that coercive pressure influences the attitude toward Green IS adoption while mimetic pressure does not. In addition, we found that there was a significant relationship between Green IS adoption, attitude, and consideration of future consequences. Finally, we found that only long term Green IS adoption was positively related to environmental performance.     

Electrical properties of ITO/benzylated cyclodextrins (-CDs (Bz))/Al diode structures

Investigations of the electrical characteristics of benzylated cyclodextrins (β-CDs (Bz)) diodes are reported. We present current–voltage characteristics and impedance spectroscopy measurements performed on partially benzylated cyclodextrins β-CDs (Bz) thin films in sandwich structures ITO/β-CDs (Bz)/Al. The static electrical characterizations show a space charge limited conduction (SCLC) and a conductivity with power low frequency behavior characteristic of a hopping transport in disordered materials. The impedance spectra can be discussed in terms of an equivalent circuit model designed as a parallel resistor R_P and capacitor C_P network in series with resistor R_S. We extract numerical values of these parameters by fitting experimental data. Their evolution with bias voltages has shown that the SCLC mechanism is characterized by an exponential trap distribution. We estimated from the capacitance voltage characteristic an acceptor concentration of about due to trap states.     

Membrane electrolysis of Bunsen reaction in the iodine–sulphur process for hydrogen production

In traditional IS process for production of hydrogen by water decomposition, the Bunsen reaction (SO₂ + I₂ + 2H₂O → H₂SO₄ + 2HI) was carried out by direct contact of SO₂ with aqueous solution of I₂ where a large excess of I₂ (8 mol) and H₂O (16 mol) were required. Excess amounts of these chemicals severely affected the overall thermal efficiency of the process and new ways including membrane electrolysis was reported in literature for carrying out Bunsen reaction where the amount of excess chemicals can be greatly reduced. We have carried out Bunsen reaction in a two-compartment membrane electrolysis cell containing graphite electrodes and Nafion 117 membrane as a separator between the two-compartments. Electrolysis was carried out at room temperature with continuous recirculation of anolyte and catholyte. Electrolysis was done in constant-current mode with current density in the range of 1.6 A/dm² to 4.8 A/dm². Initial concentrations of H₂SO₄ and HI were about 10 and 5 N, respectively and I₂/HI molar ratio in the catholyte was varied in the range of 0.25–1.5. Current efficiency was found to be close to 100% indicating absence of any side reaction at the electrodes. Cell voltage was found to vary linearly with current densities up to 80 A/dm² and for I₂/HI molar ratio in the range of 0.25–1.5 the cell voltage was found to be lowest for the value of 0.5.

Mobility, Business Process Management, Software Sourcing, and Maturity Model Trends: Propositions for the IS Organization of the Future

In this article, I argue that increased mobility, a continued emphasis on business process management, expanded options for the sourcing of enterprise system software, and IS maturity models are trends that will require new capabilities and skills for tomorrow's IS organization.     

THERMODYNAMIC CONSIDERATIONS ON THE PURIFICATION OF H2SO4 AND HIX PHASES IN THE IODINE-SULFUR HYDROGEN PRODUCTION PROCESS

The reaction equilibrium and phase equilibrium in H₂SO₄ and HIx phases produced by the Bunsen reaction of the iodine-sulfur thermochemical hydrogen production process were examined using a chemical process simulator, ESP, with a thermodynamic database based on the mixed solvent electrolyte model. At temperatures lower than ca. 110°C, the reaction of HI and H₂SO₄ produced elemental sulfur in both phases. At higher temperatures, the reverse Bunsen reaction occurred, and SO₂ was produced in the H₂SO₄ phase. In the HIx phase, conversely, SO₂ formation predominated in a narrow temperature range and H₂S was produced with the increase in temperature. The presence of N₂ gas lowered the temperature of the predominant reaction change. A feed of O₂ for purification was proposed to suppress the consumption of objective components in the H₂SO₄ phase purification, and an O₂ feed to the HIx phase for the suppression of H₂S and S impurities was proposed by the simulation.     

Feminist Philosophy and Information Systems

This paper offers a new approach to the philosophical foundations of information systems (IS) through feminist philosophy and, in particular, feminist epistemology. This can be used to expose the universalizing tendency of many information systems and to show the importance of using real-life complex examples rather than the simplified examples often favored by philosophers. Within traditional epistemology and its relation to IS, subjectivity, the propositional/skills distinction and epistemic hierarchies are subject to arguments from feminist epistemology. With respect to the emerging critical school of IS, feminist epistemology, and within that, feminist standpoint theory, are used to examine the complexities of the positivist/anti-positivist position and the related concept of emancipation. In addition, it is argued that the liberal version of emancipation encapsulated in such systems may have an effect opposite to that of emancipation These issues are illustrated in an existing expert systems project.     

A contingency model for estimating success of strategic information systems planning

Strategic information system planning (SISP) has been identified as a critical management issue. It is considered by many as the best mechanism for assuring that IT activities are congruent with those of the rest of the organization and its evolving needs.     

Role of ICTs in participatory development: An Indian experience

Participation of local communities has been important at least in two domains: (a) rural development processes in developing countries and (b) information systems design. The issue of participation becomes especially important in the contemporary contexts in which the use of information and communication technologies (ICTs) is being integrated within rural development initiatives in developing countries, for example in e-governance. This article attempts to synthesize the issues around participation from both IS and development studies literature in order to identify four key problematic areas: viz., (a) who defines the participation agenda, (b) what capabilities do stakeholders have to participate and how can this be strengthened, (c) what is the role of institutional conditions in enabling effective participation, and (d) how do local participatory processes experiences get integrated into broader networks to become sustainable. These four themes provide a theoretical framework to analyze how the use of ICTs is reconfiguring the dynamics between participation, rural development, and ICTs. This framework is applied in the context of an ICT initiative for rural development in India. Implications for both theory and practice are developed based on the need to judiciously integrate both structural and behavioral approaches to participation. © 2007 Wiley Periodicals, Inc.
