AbstractAs the scale of global commerce and opportunities for multidisciplinary collaboration increase, there is greater pressure on basic research to supply a quick return on investment (ROI). The emergence and development of digital information technologies in the new millennium have inspired a new look at how research outputs are managed and disseminated. The driving question in the minds of many research funders is this—will lowering the barriers for access increase the value of research for the greater society? This is a particularly interesting question to consider for measurement data, the greater amount of which are scattered across millions of separate, fixed publications (not to mention those never published and lingering in file drawers and on hard drives). Can the advent of cloud technologies, exchange standards, and provenance tracking facilitate improved access, evaluation, and use of data for both research and commerce? Can new value and discovery be realized through the greater aggregation of measured scientific data as “Big Data”?

Management Scholarship

In 2008 Professor Eric Godelier published a provocative essay in which he concluded that a positive dialogue between business historians and both management scientists and business management practitioners was possible. While the divide between these camps was not trivial, he nevertheless wrote that current events and scholarship was bringing them together, at least as he could observe these trends in the context of emerging French scholarship. In this current review, my own conclusion is the opposite. Management scholarship, in fact, continues to move away from the “soft” approach of the historian and more towards the “rigorous” and quantitatively biased methodology of the management sciences. My essay reviews the background of this development in terms of American business practice and scholarship, as it seeks to demonstrate how the evolution of management training in the United States brought us to the current state of affairs where “hard” drives out soft in almost every encounter. However, while I conclude that this is indeed the current reality, I do not imply any endorsement of this outcome. Rather, I end with a hope that some forms of rapprochement might be possible-yet with an acknowledgement that we will have no definitive answers to this question anytime soon.

Personal Content

Purpose The next phase of hardware technology development is focused on alternative ways to manage and store consumers’ personal content. However, even consumers who have adopted Cloud-based services have demonstrated a reluctance to move all of their personal content into the Cloud and continue to resist giving up local hard drives. This paper aims to investigate the characteristics of local hard drives and the Cloud that lead to simultaneous use. Design/methodology/approach This paper uses content analysis of online comments and ten depth interviews with simultaneous users of local hard drives and the Cloud. Findings Three factors influence the resistance to giving up local hard drives. Simultaneous users utilize local hard drives as a redundancy system and as a way to ensure the permanence of their digital content. They are unsure of the Cloud’s ability to support their content creation, management and storage activities (task-technology fit). Research limitations/implications Study findings are based on qualitative methods and thus the results cannot be considered conclusive. Practical implications The authors speculate that it is unlikely that Cloud-only will fully replace hard drives until these factors are understood and addressed by information technology developers. Cloud service providers may not be aware of how little that users understand the Cloud. In contrast to their certainty and confidence in local hard drives, simultaneous users are confused as to what the Cloud is and how it functions. This uncertainty exacerbates their risk perception and need for control. Originality/value This is the first study exploring simultaneous use of local hard drives and the Cloud with a view to understanding this behaviour in terms of the relative advantage of the incumbent technology over the new technology.

The Impact

The features of ferromagnetic fluids make it supportive for an extensive usage in loudspeakers, magnetic resonance imaging, computer hard drives, directing of magnetic drug and magnetic hyperthermia. Owing to all such potential applications, the current investigation is to understand the relationship between the thermal distribution, magnetic field and resulting fluid flow of Maxwell liquid over a stretching sheet. Investigation of thermal energy and concentration is carried out in the presence of thermal radiation, non-uniform heat sink/source, chemical reaction, Stefan blowing, magnetic dipole, thermophoresis and Brownian motion. Also, microorganisms are considered just to stabilize the suspended nanoparticles. Boundary layer approximation is employed during mathematical derivation. Based on a new constitutive relation, the governing equations are formulated and are reduced into a coupled non-linear system of equations using appropriate transformations. Further, these equations are solved numerically using fourth-order Runge–Kutta method with shooting technique. The impact of involved parameters is discussed and analysed graphically. Outcomes disclose that Newtonian liquid shows high heat transfer when compared to non-Newtonian (Maxwell) liquid for increased values of Brownian motion and thermophoresis parameters. Increased values of Peclet number declines the rate of gyrotactic microorganisms. Finally, an increase in Brownian and thermophoresis motion parameters declines the rate of heat transfer.

Optimization Methodology

This paper describes the integration of thin film ZnO strain sensors onto hard disk drive suspensions for improved vibration suppression for tracking control. Sensor location was designed using an efficient optimization methodology based on linear quadratic gaussian (LQG) control. Sensors were fabricated directly onto steel wafers that were subsequently made into instrumented suspensions. Prototype instrumented suspensions were installed into commercial hard drives and tested. For the first time, a sensing signal was successfully obtained while the suspension was flying on a disk as in normal drive operation. Preliminary models were identified from experimental transfer functions. Nominal H2 control simulations demonstrated improved vibration suppression as a result of both the better resolution and higher sensing rate provided by the sensors.

We have implemented an interactive imaging system for the interpretation of UroVysion fluorescence in situ hybridization (FISH) to improve throughput, productivity, quality control and diagnostic accuracy. We describe the Duet imaging system, our experiences with implementation, and outline the financial investment, space requirements, information technology needs, validation, and training of cytotechnologists needed to integrate such a system into a cytology laboratory. Before purchasing the imaging system, we evaluated and validated the instrument at our facility. Implementation required slide preparation changes, IT modifications, development of training programs, and revision of job descriptions for cytotechnologists. A darkened room was built to house the automated scanning station and microscope, as well as two imaging stations. IT changes included generation of storage for archival images on the LAN, addition of external hard drives for back-up, and changes to cable connections for communication between remote locations. Training programs for cytotechnologists, and pathologists/fellows/residents were developed, and cytotechnologists were integrated into multiple steps of the process. The imaging system has resulted in increased productivity for pathologists, concomitant with an expanded role of cytotechnologists in multiple critical steps, including FISH, scan setup, reclassification, and initial interpretation.
