Technical Note: Desktop Management in Practice

Desktop management is the set of activities employed to manage distributed IT resources within an organization. Reports from the late 1990s indicated that desktop management was not widely used. This article presents the results of a survey about the extent to which desktop management functions and policies are currently implemented in practice and about the perception of the benefits of desktop management. The primary conclusion of this technical note is that desktop management, despite moderately favorable perceptions of its benefits, is still not extensively implemented. However, when our data are evaluated relative to earlier reports, it appears that the level of implementation increased somewhat between 1998 and 2002

Desktop Management

Desktop management consists of the systematic activities performed by IS professionals to manage distributed computing resources throughout an organization. However, it does not appear that desktop management is being practiced extensively by organizations at this time. This paper, a comprehensive tutorial whose purpose is to raise awareness concerning the importance and potential of desktop management, examines the following issues: (1) What is the significance of desktop management? (2) What management practices constitute desktop management? (3) What are the benefits associated with implementing desktop management practices? (4) Why is desktop management not implemented? (5) What is the future of desktop management? The significance of desktop management is explored relative to total cost of ownership and the actions by the computer industry to support desktop management. Desktop management practice is described from two perspectives: (1) the software tools that enable and facilitate desktop management, and (2) the managerial activities associated with the discipline of desktop management. The benefits of desktop management covered in this paper include reduced cost of ownership, improved user productivity, and enhanced competitive advantage. However, desktop management is not widely practiced at this time, and the reasons for this state of affairs are examined briefly. Sales projections for desktop management software and interest in the topic on the Internet provide evidence that desktop management will be an important issue in the future. Issues that will impact that future include alternate ways of reducing total cost of ownership, increased use of mobile devices, and the emergence of enterprise system management tools

A Scientometric Investigation into the Validity of IS Journal Quality Measures

In this study we investigated the measurement validity of the findings in the IS journal quality stream over the past ten years. Our evaluation applied a series of validation tests to the metrics presented in these studies using data from multiple sources. The results of our tests for content, convergent, and discriminant validity, as well as those for parallel-form, test-retest, and item-to-total reliability, were highly supportive. From these findings, we conclude that recent studies in the IS journal quality stream are credible. As such, these IS journal quality measures provide appropriate indicators of relative journal quality. This conclusion is important for both academic administrators and scientometric researchers, the latter of whom depend on journal quality measures in the evaluation of published IS research

The Impact of Information Technology Infrastructure Flexibility on Strategic Alignment and Application Implementations

IT infrastructure flexibility is now being viewed as an organizational core competency that is necessary for organizations to survive and prosper in rapidly-changing, competitive, business environments. Using data from 200 U.S. and Canadian companies, this study examines the impact of the four components of IT infrastructure flexibility (compatibility, connectivity, modularity, and IT personnel) on strategic IT-business alignment and the extent to which various applications are implemented within an organization. The “extent” of implementation refers to the the organization’s experience with the particular application and the degree to which the application is implemented and used throughout the organization. The findings from analysis of a structural model provide evidence that connectivity, modularity, and IT personnel (among other considerations that we discuss in the paper) make significant, positive impacts on strategic alignment and that all four components result in significant, positive impacts on the applications implementation. The study reinforces the importance of IT infrastructure flexibility to organizations as one source for sustainable competitive advantage

Evaluation of Pt, Ni, and Ni–Mo electrocatalysts for hydrogen evolution on crystalline Si electrodes

The dark electrocatalytic and light photocathodic hydrogen evolution properties of Ni, Ni–Mo alloys, and Pt on Si electrodes have been measured, to assess the viability of earth-abundant electrocatalysts for integrated, semiconductor coupled fuel formation. In the dark, the activities of these catalysts deposited on degenerately doped p^+-Si electrodes increased in the order Ni < Ni–Mo ≤ Pt. Ni–Mo deposited on degenerately doped Si microwires exhibited activity that was very similar to that of Pt deposited by metal evaporation on planar Si electrodes. Under 100 mW cm^(−2) of Air Mass 1.5 solar simulation, the energy conversion efficiencies of p-type Si/catalyst photoelectrodes ranged from 0.2–1%, and increased in the order Ni ≈ Ni–Mo < Pt, due to somewhat lower photovoltages and photocurrents for p-Si/Ni–Mo relative to p-Si/Ni and p-Si/Pt photoelectrodes. Deposition of the catalysts onto microwire arrays resulted in higher apparent catalytic activities and similar photoelectrode efficiencies than were observed on planar p-Si photocathodes, despite lower light absorption by p-Si in the microwire structures

Measurement of the Electrical Resistance of n-Type Si Microwire/p-Type Conducting Polymer Junctions for Use in Artificial Photosynthesis

The junction between n-type silicon microwires and p-type conducting polymer PEDOT:PSS (poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate)) was investigated using a soft contact method. Dopant levels within the microwires were varied during growth to give a highly-doped region for improved contact and a low-doped region for light absorption. The low-doped region of the microwires had a dopant density of 5 X 10(17) cm(-3) while the highly-doped region had an increased dopant density of 5 X 10(18) cm(-3) over similar to 20 mu m. Uniform, highly-doped microwires, with a dopant density of 4 X 10(19) cm(3), were used as a comparison. Regions of highly-doped n-type Si microwires (N-D = 5 X 10(18) cm(-3) and 4 X 10(19) cm(-3)) contacted by PEDOT:PSS showed a significantly lower junction resistance compared to the low-doped (3 X 10(17) cm(-3)) regions of the microwire. Junctions incorporating the metal catalyst used during growth were also investigated. Microwires with copper at the interface had similar currentvoltage characteristics to those observed for the highly-doped microwire/conducting polymer junction; however, junctions that incorporated gold exhibited significantly lower resistances, decreasing the iR contribution of the junction by an order of magnitude with respect to the total voltage drop in the entire structure

Screening Historical Sexualities: A Roundtable on Sodomy, South Africa, and Proteus

(Excerpt) Proteus (2003; 100 min., Canada and South Africa) is a low-budget feature film, directed by John Greyson (Toronto) and Jack Lewis (Cape Town), that made the international rounds of “art cinema” and queer festivals in 2003 and 2004, with limited theatrical release in New York, Toronto, and other cities. The film advances Greyson’s and Lewis’s experiments with political essay-narrative forms both in their respective documentary, experimental, and dramatic videos dating back to the early 1980s (including Lewis’s Apostles of Civilized Vice [1999]) and in Greyson’s theatrical feature films beginning with Urinal in 1988. Based on an early-eighteenth-century court record, Proteus narrates the meeting, sexual relationship, and eventual trial and execution for sodomy of two prisoners in the Dutch Cape Colony, the Dutchman Rijkhaart Jacobsz and the Khoi Claas Blank. Subsidiary narratives focus on the Scottish botanist Virgil Niven, who observed the prisoners, and on the contemporaneous crackdown on sodomites in Amsterdam. GLQ initiated the following “virtual conversation” among the two directors, Israeli queer legal theorist Noa Ben-Asher, American film scholar R. Bruce Brasell, American film critic Daniel Garrett, and South African historian Susan Newton-King. Though it will “spoil” the plot for readers who have not seen the movie, we offer it as a lively debate about one of the more interesting entries in the new “new queer cinema.” The debate explores the precarious and artful interrelationship of histories, nations, narratives, and the law; cinematic intent and spectatorial interpretation; same-sexuality, conjugality, and difference; and even, as one participant dares to put it, love

Photoelectrochemical Hydrogen Evolution Using Si Microwire Arrays

Arrays of B-doped p-Si microwires, diffusion-doped with P to form a radial n+ emitter and subsequently coated with a 1.5-nm-thick discontinuous film of evaporated Pt, were used as photocathodes for H_2 evolution from water. These electrodes yielded thermodynamically based energy-conversion efficiencies >5% under 1 sun solar simulation, despite absorbing less than 50% of the above-band-gap incident photons. Analogous p-Si wire-array electrodes yielded efficiencies <0.2%, largely limited by the low photovoltage generated at the p-Si/H_2O junction
