    Neural network technology for knowledge resource management (1996)
    Bingley : Emerald
    Management decision 34 (1996), S. 20-24

    Notes: The adoption of a knowledge-based system requires that users, experts and managers have good understanding of the concepts of information resource management (IRM) and knowledge resource management (KRM). Proposes a KRM concept which aims to organize knowledge, ensure a global control of conceptual resources and reduce heterogeneity of knowledge. Uses the neural network technology to integrate both the IRM and KRM concepts through the generation of neural decision support. Such a technology will not only help users understand situations unknown to the organization's knowledge-based systems but also more efficiently to access stored knowledge.

    Expert system: defection and perfection (1999)

    Notes: Unlike other computer-based information systems, expert systems (ES) are characterized by the satisficing and conservative behavior of their users. Shows that the learning curve may be used to model user dependency on ES technology. Even though user dependency relates to ES quality control parameters (for example, Raggad's 13 ES quality attributes) only dynamic or late binding features really affect ES dependency: ES learning capability and ES recommendation anticipation. There is hence a learning race between the system and the user. If user learning prevails, then there will be user defection. If system learning prevails, then there will be system perfection. Proposes failure analysis based on user defection due to the absence or underutilization of machine learning. ES owners can adopt this model to design a subsystem capable of transforming user defection analysis into a strategic plan for ES management.

    Possibilistic group support system for pricing and inventory problems (2000)
    Bradford : Emerald
    Logistics information management 13 (2000), S. 68-76 
    Details
    ISSN: 0957-6053
    Source: Emerald Fulltext Archive Database 1994-2005
    Topics: Economics
    Notes: Proposes a possibilistic group support system (PGSS) for the retailer pricing and inventory problem when possibilistic fluctuations of product parameters are controlled by a set of possibilistic optimality conditions. Experts in various functional areas convey their subjective judgement to the PGSS in the form of analytical models (for product parameters estimation), fuzzy concepts (facts), and possibilistic propositions (for validation and choice procedures). Basic probability assignments are used to elicit experts' opinions. They are then transformed into compatibility functions for fuzzy concepts using the falling shadow technique. Evidence is processed in the form of fuzzy concepts, then is rewritten back to basic probability assignments using the principle of least ignorance on randomness. The PGSS allows the user (inventory control) to examine a trade-off between the belief value of a greater profit and a lower amount of randomness associated with it.

    Information systems concepts: a guide for executives (1997)

    Notes: Explains that information technology (IT) applications, especially as reinforcer of competitive advantage, has received prodigious attention. Despite a generous coverage of information systems (IS) concepts, there is still a clear communication gap between line managers and IS managers that is harming the gain of strategic advantage. The lack of understanding between line managers and information specialists can create serious conflicts in interpreting corporate goals and strategic objectives. Presents an easy and user-friendly organization of fundamental IS concepts in order to promote a higher level of communication between the two groups and produce a finer alignment of IT strategy and overall corporate strategy.

    Assessing the perceptions of human resource managers toward nepotism: A cross-cultural study (1998)
    Bingley : Emerald
    International journal of manpower 19 (1998), S. 554-570

    Notes: This empirical study identifies, examines, and compares the perceptions of HRMs in selected organizations in one developed country (the USA) and one less-developed country (Jordan) toward arguments supporting nepotism. It also identifies, examines, and compares the perceptions of these HRMs toward arguments against nepotism in these two countries. The results of this study indicate that few HRMs in each country have agreed with arguments supporting nepotism. In contrast, many of these HRMs have agreed with arguments against nepotism. While there are differences between the perceptions of US and Jordanian HRMs toward arguments for and against nepotism, these differences are not significant.

    Decision support system: use IT or skip IT (1997)

    Notes: Using a decision support system (DSS) delays the decision-making process and commits the user to the cost of invoking the system. The existing configurations of decision support systems do not guarantee the profitability of the DSS. If the DSS generates messages that the decision maker can anticipate, then the cost and waiting time as a result of invoking the DSS will not be justified. Proposes a decision support system equipped with a knowledge-based model that tells the decision maker, prior to invoking the DSS, whether or not it is profitable to invoke the DSS; if invoking the DSS is not profitable, then the decision maker will have to base the decision on pure managerial subjective judgement. Uses a numerical example to illustrate the work of the proposed DSS.

    Effects of information structure and problem solving on decision-support system choice (1996)

    Notes: Examines the effects of decision unstructuralness (unstructuredness + noisiness) on decision-support systems (DSS) adoption. Suggests that end-users are sensitive to "unstructuralness" when they select a decision support approach. Problem structuring at the intelligence phase generates the first signal about DSS usefulness. If this signal is in favour of DSS, the manager either immediately adopts the DSS, or performs problem solving at the design phase. At this phase a new signal will be generated thus, confirming or denying DSS usefulness. This confirms that problem structuring prevails in making the DSS adoption decision. That is, in making the DSS adoption decision, priority is given to problem structuring in the intelligence phase.

    Influence of laser induced hot electrons on the threshold for shock ignition of fusion reactions (2016)
    American Institute of Physics (AIP)
    Details
    Publication Date: 2016-07-19
    Description: The effects of Hot Electrons (HEs) generated by the nonlinear Laser-Plasma Interaction (LPI) on the dynamics of Shock Ignition Inertial Confinement Fusion targets are investigated. The coupling between the laser beam, plasma dynamics and hot electron generation and propagation is described with a radiative hydrodynamics code using an inline model based on Paraxial Complex Geometrical Optics [Colaïtis et al ., Phys. Rev. E 92 , 041101 (2015)]. Two targets are considered: the pure-DT HiPER target and a CH-DT design with baseline spike powers of the order of 200–300 TW. In both cases, accounting for the LPI-generated HEs leads to non-igniting targets when using the baseline spike powers. While HEs are found to increase the ignitor shock pressure, they also preheat the bulk of the imploding shell, notably causing its expansion and contamination of the hotspot with the dense shell material before the time of shock convergence. The associated increase in hotspot mass (i) increases the ignitor shock pressure required to ignite the fusion reactions and (ii) significantly increases the power losses through Bremsstrahlung X-ray radiation, thus rapidly cooling the hotspot. These effects are less prominent for the CH-DT target where the plastic ablator shields the lower energy LPI-HE spectrum. Simulations using higher laser spike powers of 500 TW suggest that the CH-DT capsule marginally ignites, with an ignition window width significantly smaller than without LPI-HEs, and with three quarters of the baseline target yield. The latter effect arises from the relation between the shock launching time and the shell areal density, which becomes relevant in presence of a LPI-HE preheating.
