Human Resource Information Systems for Competitive Advantage: Interviews with Ten Leaders
[Excerpt] Increasingly, today\u27s organizations use computer technology to manage human resources (HR). Surveys confirm this trend (Richards-Carpenter, 1989; Grossman and Magnus, 1988; Human Resource Systems Professionals 1988; KPMGPeat Marwick, 1988). HR professionals and managers routinely have Personnel Computers (PCs) or computer terminals on their desks or in their departments. HR computer applications, once confined to payroll and benefit domains, now encompass incentive compensation, staffing, succession planning, and training. Five years ago, we had but a handful of PC-based software applications for HR management. Today, we find a burgeoning market of products spanning a broad spectrum of price, sophistication, and quality (Personnel Journal, 1990). Top universities now consider computer literacy a basic requirement for students of HR, and many consulting firms and universities offer classes designed to help seasoned HR professionals use computers in their work (Boudreau, 1990). Changes in computer technology offer expanding potential for HR management (Business Week, 1990; Laudon and Laudon, 1988)

Human Resource Automation for Competitive Advantage: Case Studies of Ten Leaders
[Excerpt] This report describes findings from a study that we view as a first step in a long term research program conducted by the CAHRS to address sponsor concerns. One of this program\u27s objectives is to identify organization dimensions that predict the success or failure of computer systems in HR. A Second objective is to specify a model that will increase value-added decisions about HR computer system investments and guide the planning and implementation of HR technology strategies
Ongoing transients in carbonate compensation
Uptake of anthropogenic CO2 is acidifying the oceans. Over the next 2000 years, this will modify the dissolution and preservation of sedimentary carbonate. By coupling new formulas for the positions of the calcite saturation horizon, zsat, the compensation depth, zcc, and the snowline, zsnow, to a biogeochemical model of the oceanic carbonate system, we evaluate how these horizons will change with ongoing ocean acidification. Our model is an extended Havardton-Bear-type box model, which includes novel kinetic descriptions for carbonate dissolution above, between, and below these critical depths. In the preindustrial ocean, zsat and zcc are at 3939 and 4750 m, respectively. When forced with the IS92a CO2 emission scenario, the model forecasts (1) that zsat will rise rapidly (“runaway” conditions) so that all deep water becomes undersaturated, (2) that zcc will also rise and over 1000 years will pass before it will be stabilized by the dissolution of previously deposited CaCO3, and (3) that zsnow will respond slowly to acidification, rising by ∼1150 m during a 2000 year timeframe. A further simplified model that equates the compensation and saturation depths produces quantitatively different results. Finally, additional feedbacks due to acidification on calcification and increased atmospheric CO2 on organic matter productivity strongly affect the positions of the compensation horizons and their dynamics.
Crowdfunding as Donations to Entrepreneurial Firms
The bulk of today's (“preorder-,” “reward-,” “gift-,” and “donation-based”) crowdfunding raises funds for small, private entrepreneurial ventures without granting funders private claims to the projects’ income or the ability to guarantee the realization and delivery of project outcomes. We theorize and show empirically – via a mixed-method approach applied to a representative and remarkably informative case – that the payoff structure for crowdfunders, akin to a public good contribution problem, leads to the tangible value of main project outputs exerting little influence on contributions to crowdfunding. This then raises the question of which funder motivations fund seekers may have to address to crowdfund their projects. We demonstrate the especially large role of non-pecuniary motivations and pinpoint three particular motivations that profit-seeking entrepreneurs may stimulate to be financed through crowdfunding. The findings hold important implications for entrepreneurs’ crowdfunding strategies, platform design, and our understanding of how this funding institution works in general. The study also adds to emerging research on the implications of the public good nature of crowdfunding
A Knowledge-centric Examination of Signaling and Screening Activities in the Negotiation for Information Systems Consulting Services
In many professional exchanges, information asymmetry is bilateral, which means that both parties hold information that the other party lacks and, as a result, both parties have the means to be opportunistic. To counter this asymmetry, both parties signal and screen information as they negotiate a consulting engagement. In this paper, we report on how a professional service provider and recipient typically use signaling and screening. The findings highlight that both parties signal and screen and withhold information and that the extent of project knowledge (tacit or explicit) affects how they do so. Tacit knowledge-centric projects have more signaling and screening events than explicit knowledge-centric projects but many of these signals actually increase the amount of information asymmetry
Gain properties of dye-doped polymer thin films
Hybrid pumping appears as a promising compromise in order to reach the much
coveted goal of an electrically pumped organic laser. In such configuration the
organic material is optically pumped by an electrically pumped inorganic device
on chip. This engineering solution requires therefore an optimization of the
organic gain medium under optical pumping. Here, we report a detailed study of
the gain features of dye-doped polymer thin films. In particular we introduce
the gain efficiency , in order to facilitate comparison between different
materials and experimental conditions. The gain efficiency was measured with
various setups (pump-probe amplification, variable stripe length method, laser
thresholds) in order to study several factors which modify the actual gain of a
layer, namely the confinement factor, the pump polarization, the molecular
anisotropy, and the re-absorption. For instance, for a 600 nm thick 5 wt\% DCM
doped PMMA layer, the different experimental approaches give a consistent value
80 cm.MW. On the contrary, the usual model predicting the gain
from the characteristics of the material leads to an overestimation by two
orders of magnitude, which raises a serious problem in the design of actual
devices. In this context, we demonstrate the feasibility to infer the gain
efficiency from the laser threshold of well-calibrated devices. Besides,
temporal measurements at the picosecond scale were carried out to support the
analysis.Comment: 15 pages, 17 figure
Prevention of occupational diseases in small and medium-sized manufacturing enterprises in QUEBEC (CANADA) – Study of prevention management practices
Prevention of accidents and occupational diseases plays a major role in the viability of small and medium-sized manufacturing enterprises. However, occupational health and safety conditions in this setting are often precarious compared to large corporations, in which occupational diseases occur eight times less frequently. In a previous study [1], it has been identified, by reviewing the literature, the measures practiced by managers of businesses in this category in the province of Quebec in their efforts to decrease the incidence of occupational diseases. The initial research work reduced these measures to a catalog of elements of management. In the present article, the findings on the application of these elements will be presented, based on a survey of about 400 manufacturing businesses, of which 252 agreed to answer the questionnaire. The present article provides a descriptive statistic from the analysis of the responses. This work allowed to portray the strengths and deficiencies of occupational disease risk management practices in Quebec based on complete and valid responses from 32 small and medium-sized enterprises (SMEs). Overall, this portrayal reflects a serious effort to take up the cause of occupational health and safety in this type of business. It nevertheless reveals room for improvement of the implementation of health and safety risk management systems, and prevention of musculoskeletal diseases and hearing loss, which were found to occur in respectively 63% and 25% of these companies. This work therefore recommends that these diseases be treated as a priority by researchers and expert practitioners of occupational health and safety
Automatic Detection and Prediction of the Transition Between the Behavioural States of a Subject Through a Wearable CPS
The PRESLEEP project is aimed at the fine assessment and validation of the proposed proprietary methodology/technology, for the automatic detection and prediction of the transition between the behavioural states of a subject (e.g. wakefulness, drowsiness and sleeping) through a wearable Cyber Physical System (CPS). The Intellectual Property (IP) is based on a combined multi-factor and multi-domain analysis thus being able to extract a robust set of parameters despite of the, generally, low quality of the physiological signals measured through a wearable system applied to the wrist of the subject. An application experiment has been carried out at AVL, based on reduced wakefulness maintenance test procedure, to validate the algorithm’s detection and prediction capability once the subject is driving in the dynamic vehicle simulator
The relationship between mitochondrial function and walking performance in older adults with a wide range of physical function.
Age related declines in walking performance may be partly attributable to skeletal muscle mitochondrial dysfunction as mitochondria produce over 90% of ATP needed for movement and the capacity for oxidative phosphorylation decreases with age.
Participants were from two studies: an ancillary to the Lifestyle Interventions and Independence for Elders (LIFE) Study (n=33), which recruited lower functioning participants (Short Physical Performance Battery [SPPB], 7.8±1.2), and the Study of Energy and Aging-Pilot (SEA, n=29), which enrolled higher functioning (SPPB, 10.8±1.4). Physical activity was measured objectively using the Actigraph accelerometer (LIFE) and SenseWear Pro armband (SEA). Phosphocreatine recovery following muscle contraction of the quadriceps was measured using (31)P magnetic resonance spectroscopy and ATPmax (mM ATP/s) was calculated. Walking performance was defined as time (s) to walk 400m at a usual-pace. The cross-sectional association between mitochondrial function and walking performance was assessed using multivariable linear regression.
Participants were 77.6±5.3years, 64.2% female and 67.2% white. ATPmax was similar in LIFE vs. SEA (0.52±0.14 vs. 0.55±0.14, p=0.31), despite different function and activity levels (1.6±2.2 vs.77.4±73.3min of moderate activity/day, p<0.01). Higher ATPmax was related to faster walk-time in SEA (r(2)=0.19, p=0.02,); but not the LIFE (r(2)<0.01, p=0.74) cohort.
Mitochondrial function was associated with walking performance in higher functioning, active older adults, but not lower functioning, sedentary older adults
