Two-Stage Ordering Policy under Buyer’s Minimum-Commitment Quantity Contract  [PDF]
Hsi-Mei Hsu, Zi-Yin Chen
American Journal of Operations Research (AJOR) , 2011, DOI: 10.4236/ajor.2011.13012
Abstract: In this paper we consider a two-stage ordering problem with a buyer’s minimum commitment quantity contract. Under the contract the buyer is required to give a minimum-commitment quantity. Then the manufacturer has the obligations to supply the minimum-commitment quantity and to provide a shortage compensation policy to the buyer. We formulate a dynamic optimization model to determine the manufacturer’s two stage order quantities for maximizing the expected profit. The conditions for the existence of the optimal solution are defined. And we also develop a procedure to solve the problem. Numerical examples are given to illustrate the proposed solution procedure and sensitivity analyses are performed to find managerial insights.
Moral Judgment: Truth, Order and Consequence  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.65061
Abstract: Often we make snap moral judgments based on limited information. For instance upon reading a newspaper headline we very quickly decide on whether the implied outcome is good or bad. However, in situations like this we are also likely to revise our judgments when we read the main story and the conclusion of the article. One question yet to be answered is whether we adjust our moral judgments in a systematic way as we gain more details about a moral scenario. Two experiments (lab-based, online) addressed this question along with the influence of other factors on moral judgments (the origin of the moral scenario, the severity of the consequence of the scenario). Across both experiments, moral judgments were: 1) generally adjusted downwards as more information was presented; 2) more severe for headlines than the main story or the conclusion; 3) more severe for scenarios that were fabricated than real life stories; 4) more severe when the conclusion involved a severe consequence than a non-severe consequence.
Actualización terapéutica sobre diarrea persistente
Ruiz Silva,María Dolores; Frómeta Hierrezuelo,Ana Rosa; García Martínez,Rosa María; Ximelis Morales,Angel Alfonso; Cobas Ruiz,Julia;
Revista Cubana de Pediatr?-a , 2009,
Abstract: a bibliographic review was made on the persistent diarrhea and its treatment using the updated printed review and the electronic publications to give information on entity and behavior followed since that the diagnosis is made. treatment pillars are showed according the more coincident results in medical literature, as well as the prevention ways of consequences from late diagnosis and treatment. authors emphasize the significance of breastfeeding, the proper dietetic-nutritional balance, and the elimination of risk factor that may to have an impact on the appearance and persistence of this affection.
Updating Geologic Models using Ensemble Kalman Filter for Water Coning Control  [PDF]
Cesar A. Mantilla, Sanjay Srinivasan, Quoc P. Nguyen
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.35063
Abstract: This study investigated the feasibility of updating prior uncertain geologic models using Ensemble Kalman filter for controlling water coning problems in horizontal wells. Current downhole data acquisition technol-ogy allows continuous updating of the reservoir models and real-time control of well operations. Ensemble Kalman Filter is a model updating algorithm that permits rapid assimilation of production response for res-ervoir model updating and uncertainty assessment. The effect of the type and amount of production data on the updated geologic models was investigated first through a synthetic reservoir model, and then imple-mented on a laboratory experiment that simulated the production of a horizontal well affected by water con-ing. The worth of periodic model updating for optimized production and oil recovery is demonstrated.
DARM: Decremental Association Rules Mining  [PDF]
Mohamed Taha, Tarek F. Gharib, Hamed Nassar
Journal of Intelligent Learning Systems and Applications (JILSA) , 2011, DOI: 10.4236/jilsa.2011.33019
Abstract: Frequent item sets mining plays an important role in association rules mining. A variety of algorithms for finding frequent item sets in very large transaction databases have been developed. Although many techniques were proposed for maintenance of the discovered rules when new transactions are added, little work is done for maintaining the discovered rules when some transactions are deleted from the database. Updates are fundamental aspect of data management. In this paper, a decremental association rules mining algorithm is present for updating the discovered association rules when some transactions are removed from the original data set. Extensive experiments were conducted to evaluate the performance of the proposed algorithm. The results show that the proposed algorithm is efficient and outperforms other well-known algorithms.
Structural Reanalysis of Dynamic Systems Using Model Updating Method  [PDF]
Kyoung-Bong Han
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.310122
Abstract: Model updating methodologies are invariably successful when used on noise-free simulated data, but tend to be unpredictable when presented with real experimental data that are unavoidably corrupted with uncorrelated noise content. In this paper, reanalysis using frequency response functions for correlating and updating dynamic systems is presented. A transformation matrix is obtained from the relationship between the complex and the normal frequency response functions of a structure. The transformation matrix is employed to calculate the modified damping matrix of the system. The modified mass and stiffness matrices are identified from the normal frequency response functions by using the least squares method. A numerical example is employed to illustrate the applicability of the proposed method. The result indicates that the present method is effective.
Dynamic Moral Judgments and Emotions  [PDF]
Magda Osman
Psychology (PSYCH) , 2015, DOI: 10.4236/psych.2015.68090
Abstract: We may experience strong moral outrage when we read a news headline that describes a prohibited action, but when we gain additional information by reading the main news story, do our emotional experiences change at all, and if they do in what way do they change? In a single online study with 80 participants the aim was to examine the extent to which emotional experiences (disgust, anger) and moral judgments track changes in information about a moral scenario. The evidence from the present study suggests that we systematically adjust our moral judgments and our emotional experiences as a result of exposure to further information about the morally dubious action referred to in a moral scenario. More specifically, the way in which we adjust our moral judgments and emotions appears to be based on information signalling whether a morally dubious act is permitted or prohibited.
Considera??es finais sobre os helmintos da Cole??o do Instituto Bacteriológico de S?o Paulo, incorporada à Cole??o Helmintológica do Instituto Oswaldo Cruz
Noronha, Dely;Pinto, Roberto Magalh?es;
Revista Brasileira de Zoologia , 2007, DOI: 10.1590/S0101-81752007000400039
Abstract: this note supplies recent data on the present status of helminths collected by adolpho lutz (bacteriological institute of s?o paulo) between 1905-1909, studied by travassos (1917) and referred by the author as deposited in the helminthological collection of the oswaldo cruz institute (chioc). in the present paper, some innacuracies related to the paper of travassos (1917) and that have been overlooked to date are evaluated and elucidated.
Environmental Governance as Stochastic Belief Updating: Crafting Rules to Live by
Daniel W. Bromley
Ecology and Society , 2012, DOI: 10.5751/es-04774-170314
Abstract: The idea that humans can “manage” nature is a modernist conceit. Natural systems and social (human) systems are always in the process of becoming. In this setting of unknowable dynamic emergence, it is not possible to design institutional arrangements—rules to live by—that permit an activity called “management.” The more fundamental challenge to the conceit of management is that humans are never sure what we want until we are put in a situation of having to work it out. We learn what we want by learning about what it might be possible for us to have. Science, properly engaged with the public, can contribute to this learning process. But science cannot hold itself up as an activity that produces truth about what it would be better to do. Sapient adults work that out, just as we work out the evolving meaning to us of the natural system. Science practiced outside of this realm of human meaning is impertinent.
