IS Success Model for Evaluating Cloud Computing for Small Business Benefit: A Quantitative Study

Information system (IS) success has been extensively researched to frame key attributes of an information system or technology to understand its benefit to business. One definition of IS success is the adoption and extensive use of an information system (Robey & Zeller, 1978). In the present era of cloud computing, as in former IS eras, successful implementation is critical for achieving business success in all enterprise types. IS success is also described as a lagging multifaceted measure of technology effectiveness for a business. Early adopters of a new technology are a rich resource to determine benefits for later adopters, and this is true for those businesses looking to implement cloud computing. This is critically important for small businesses. Cloud computing is characterized as a 21st century model of acquiring computational resources and services through convenient on-demand provisioning mechanisms via a shared network (Mell & Grance, 2010, p. 50). With the resource challenges of small businesses, the selection of a particular cloud computing model can result in business success or calamity. Many small businesses realize they need to make key investments in the latest technologies to advance their business, but many have one opportunity to make the best choice and to do it right. Small businesses typically operate with limited capital resources to invest in new IS technologies, as well as fund their ongoing upgrades, enhancements, and support. The intent of this research study is to define an IS framework that small businesses can use to determine the benefits of a particular cloud computing solution before adoption, based on the efforts of select small businesses that are early adopters of cloud computing. This research will determine the essential features and attributes that enable cloud computing success for small businesses in their targeted marketplaces. The primary success constructs of this study will focus on the overall cloud quality, experience, and benefit. The results of this research will lead to an enhanced IS success model that will enable small businesses to target specific cloud-based computing services that align with their business requirements to enable them to achieve business success

Influence of Cloud-Based Computing on User Productivity

Cloud computing is a rapidly expanding IT paradigm for providing computational resources to enterprises and end-users. In recent research conducted by Garrison, he concludes that the key enablers of cloud deployment success are chiefly dependent upon relational (trust), technical, and managerial dependencies primarily borne by the firm contracting cloud computing services. In this document we expand upon their research to consider key metrics for the enterprise to consider in the successful adoption of cloud computing with a focus on the end-user. We review of applicable theories which were utilized during previous major IT shifts and well as investigate key user perspectives. The intent is to provide a model which will focus on cloud computing end-user success

Extending the DeLone and McLean IS Success Model to Cloud Computing

This research in progress paper proposes a parsimonious IS success model to measure net benefits for cloud computing, based on the 2003 Delone and McLean IS Success Model and subsequent IS success research. Early adopters of new technology, such as cloud computing, are a rich resource of information to identify benefits for later adopters. The primary constructs of our model focus on the overall cloud quality (service and system), experience (organization satisfaction and use), and net benefits and identifies relationships among these constructs. To test this model, a quantitative study will survey organizations using cloud computing to determine the benefits of the cloud computing solution they have adopted. The result of this research will produce findings which will enable organizations to target specific cloud-based computing services that align with their organizational requirements to enable them to achieve success

Achirality in the low temperature structure and lattice modes of tris(acetylacetonate)iron(iii)

Tris(acetylacteonate) iron(III) is a relatively ubiquitous mononuclear inorganic coordination complex. The bidentate nature of the three acetylacteonate ligands coordinating around a single centre inevitably leads to structural isomeric forms, however whether or not this relates to chirality in the solid state has been questioned in the literature. Variable temperature neutron diffraction data down to T = 3 K, highlights the dynamic nature of the ligand environment, including the motions of the hydrogen atoms. The Fourier transform of the molecular dynamics simulation based on the experimentally determined structure was shown to closely reproduce the low temperature vibrational density of states obtained using inelastic neutron scattering

A 3,5-dinitro­benzoyl derivative of a stereoisomer of glycerol menthonide

The title compound, [(2S,5R,6S,9R)-6-isopropyl-9-methyl-1,4-dioxaspiro­[4.5]dec-2-yl]methyl 3,5-dinitro­benzoate, C20H26N2O8, was synthesized as part of a study of three-carbon stereochemical systems. The crystallographic assignment of the absolute stereochemistry is consistent with having started with (−)-menthone, the acetal carbon is R and the secondary alcohol is S. This brings the dinitro­benzoate into approximately the same plane as the menthyl ring and anti to the isopropyl group. Close inter­molecular C=O⋯NO2 contacts between neighboring mol­ecules [2.8341 (16) Å] contribute to the packing arrangement. The structure was refined as a pseudo-merohedral twin (monoclinic space group P21 emulating the ortho­rhom­bic space group C2221). Application of the twin law 100, 00, 0 gave a 2:1 ratio of twin moieties [refined BASF value = 0.3790 (7)]

5,6-Di­oxo-1,10-phenanthrolin-1-ium trifluoro­methane­sulfonate

In the structure of the title salt, C12H7N2O2 +·CF3SO3 −, the cation participates in hydrogen bonding with the dione group of an adjacent cation as well as with the trifluoro­methane­sulfonate anion. In addition, there is an extensive network of C—H⋯O inter­actions between the cations and anions. There are two formula units per asymmetric unit. The crystal studied exhibits inversion twinning

Measurement of the quasi-elastic axial vector mass in neutrino-oxygen interactions

The weak nucleon axial-vector form factor for quasi-elastic interactions is determined using neutrino interaction data from the K2K Scintillating Fiber detector in the neutrino beam at KEK. More than 12,000 events are analyzed, of which half are charged-current quasi-elastic interactions nu-mu n to mu- p occurring primarily in oxygen nuclei. We use a relativistic Fermi gas model for oxygen and assume the form factor is approximately a dipole with one parameter, the axial vector mass M_A, and fit to the shape of the distribution of the square of the momentum transfer from the nucleon to the nucleus. Our best fit result for M_A = 1.20 \pm 0.12 GeV. Furthermore, this analysis includes updated vector form factors from recent electron scattering experiments and a discussion of the effects of the nucleon momentum on the shape of the fitted distributions.Comment: 14 pages, 10 figures, 6 table

Study of e+e- --> pi+ pi- pi0 process using initial state radiation with BABAR

The process e+e- --> pi+ pi- pi0 gamma has been studied at a center-of-mass energy near the Y(4S) resonance using a 89.3 fb-1 data sample collected with the BaBar detector at the PEP-II collider. From the measured 3pi mass spectrum we have obtained the products of branching fractions for the omega and phi mesons, B(omega --> e+e-)B(omega --> 3pi)=(6.70 +/- 0.06 +/- 0.27)10-5 and B(phi --> e+e-)B(phi --> 3pi)=(4.30 +/- 0.08 +/- 0.21)10-5, and evaluated the e+e- --> pi+ pi- pi0 cross section for the e+e- center-of-mass energy range 1.05 to 3.00 GeV. About 900 e+e- --> J/psi gamma --> pi+ pi- pi0 gamma events have been selected and the branching fraction B(J/psi --> pi+ pi- pi0)=(2.18 +/- 0.19)% has been measured.Comment: 21 pages, 37 postscript figues, submitted to Phys.

We present a measurement of the branching fraction for the decay B- --> D0 K*- using a sample of approximately 86 million BBbar pairs collected by the BaBar detector from e+e- collisions near the Y(4S) resonance. The D0 is detected through its decays to K- pi+, K- pi+ pi0 and K- pi+ pi- pi+, and the K*- through its decay to K0S pi-. We measure the branching fraction to be B.F.(B- --> D0 K*-)= (6.3 +/- 0.7(stat.) +/- 0.5(syst.)) x 10^{-4}.Comment: 7 pages, 1 postscript figure, submitted to Phys. Rev. D (Rapid Communications
