  1. Whole-Genome Sequencing During Measles Outbreaks

    Paul A. Rota; Bettina Bankamp
    measles viruses is an important compo-nent of laboratory-based surveillance for measles virus. The genetic information can classify measles viruses as endemic or imported and can help map the trans-mission pathways of the virus. Since viro-logic evidence demonstrating the absence of an endemic genotype of measles virus is one of the key criteria for verification of measles elimination [1], adequate viro-logic surveillance must be conducted on a global scale. The current recommenda-tion is to obtain appropriate samples for viral genotyping from at least 80 % of out-breaks [2]. In addition, sequence analysis is currently the only method available to con-firm measles...

    Erp Systems; Family Smes
    Currently, the business environment is dramatically changing. Globa-lization, increasing competition and expanding markets are main factors that influence the business complexity (Umble et al., 2003). Those rapid changing business environment have forced firms to introduce and mana-ge successfully the organizational change to achieve and sustain competiti-ve advantage. Enterprise Resource Planning (ERP) systems are considered a necessary condition to compete in the market and to manage the com-plexity. Such systems respond to managers ’ needs concerning accurate and timely information in order to achieve business objectives. ERP systems help organizations to reduce operating costs and improve business process management and allow...

  3. Repeated Administration of a Mutant Cocaine Esterase: Effects on Plasma Cocaine Levels, Cocaine-Induced Cardiovascular Activity, and Immune Responses in Rhesus Monkeys

    Gregory T; Nicholas W. Lukacs; Roger K. Sunahara; James H. Woods; Mei-chuan Ko
    Previous studies have demonstrated the capacity of a long-acting mutant form of a naturally occurring bacterial double mutant cocaine esterase (DM CocE) to antagonize the reinforc-ing, discriminative, convulsant, and lethal effects of cocaine in rodents and reverse the increases in mean arterial pressure (MAP) and heart rate (HR) produced by cocaine in rhesus monkeys. This study was aimed at characterizing the immuno-logic responses to repeated dosing with DM CocE and deter-mining whether the development of anti-CocE antibodies al-tered the capacity of DM CocE to reduce plasma cocaine levels and ameliorate the cardiovascular effects of cocaine in rhesus monkeys. Under control...

    Social production has risen on the agenda of the social sciences. Yet most observers have been reluctant to confront the question of the value of these practices. Instead they have mostly been characterised as ‘free’, ‘common ’ or beyond value. This article argues that far from being free, social production abides to a particular value logic, an ‘ethical economy ’ where value is relat-ed not to the input of labour time, but to the ability to give productive organ-isation to a diffuse connectivity or, which is the same thing, to transform weak ties into affectively significant strong ones. The article...

  5. DOI 10.1177/0022343308100714 US Aid Allocation: The Nexus of Human Rights, Democracy, and Development*

    Tijen Demirel-pegg; James Moskowitz
    Respect for human rights is one of several factors influencing US aid allocation decisions. Whereas previous research identifies human rights practices as being of secondary importance, it typically does not explore whether there is a more complicated relationship between human rights practices and US aid allocation. The authors argue that the impact of human rights varies at different levels of democracy and economic development. Employing data on 151 countries from 1977 to 2004, this study also investigates whether there has been an increase in the impact of human rights practices since the end of the Cold War. The results of...

    Bowel obstruction in the terminally ill is a relatively common complica-tion. The classic therapy of IV hydra-tion with nasogastric suction is con-traindicated due to inefficacy and patient discomfort. Modern therapy consists of state-of-the-art pharmaco-logic treatments, as well as the judi-cious use of surgical interventions in selected cases. Many patients can be relatively symptom-free and can eat and drink as tolerated.

  8. Outline of an Action-Oriented Classification of Mental Disorders: A Hypothetical Model

    Bernhard J. Mitterauer
    Abstract: The outline of an action-oriented classification of mental disorders is mainly theoretically proposed. Based on the discussion and interpretation of the “Schichtenregel ” (three-layer-rule) by the German psychiatrist Karl Jaspers, a synaptic model is elaborated for the pathophysiology of depression, mania and schizophrenia. According to a logic of balance, synapses may be balanced, underbalanced (depression), overbalanced (mania), or unbalanced (schizophrenia). From a psychological point of view, patients with a major depression are hyperintentional, patients with mania are hypointentional, and in the case of schizophrenia they are dysintentional. Decisive in the synaptic model proposed is the number of receptors for...

  9. Control and Hardware-in-the-Loop Simulation of an Automated

    X-y Song; Z-x Sun; X-j Yang; G-m Zhu
    Abstract: To enable a realistic automated manual transmission (AMT) system performance evaluation and rapid prototyping, this paper focuses on constructing a practical Simulink model and a hardware-in-the-loop (HIL) real-time simulation. The working principle and dynamic characteristics of the AMT system are first explored. The driveline, the engine control, and the dry clutch are modelled and analysed. In particular, a dynamic model for the hydraulic clutch actuator that is currently used in the actual transmissions is developed. To evaluate the performance and operation characteristics of the AMT system, the control methodology to ensure desirable performance is studied. The gearshift control logic...

  10. Luis Roniger* ➲ Global Times once Again: Representative Democracy

    Countervailing Trends In Iberoamerica
    Abstract: In the late 1990s and early 2000s democratic expectations were replaced by the discredit of democracy. Analyzing this trend, this study looks at the interplay of poli-tics and the economic realm. It discusses the fragility and persistence of democracy and identifies the effect of recent macro-economic policies, the weakening of public goods, processes of dualization in forms of participation in the public domain. It also analyzes contrasting political trends, which involve some innovative projects institutionalizing democratic controls, but also new forms of populism and clientelism buttressed by pover-ty, unemployment and violence which reinforce the logic of exclusion. Finally, it...

    We present an authorization logic that permits reasoning with explicit time. Following a proof-theoretic approach, we study the meta-theory of the logic, including cut elimination. We also demonstrate formal connections to proof-carrying authorization’s existing approach for handling time and comment on the enforceability of our logic in the same framework. Finally, we illustrate the expressiveness of the logic through examples, including those with complex interactions between time, authorization, and mutable state. 1This research was sponsored by the Air Force Research Laboratory under grant no. FA87500720028. The views and conclusions contained in this document are those of the authors and should...

  13. Process-Algebraic Interpretations of Positive Linear and Relevant Logics

    Kista Sweden
    We investigate the use of positive linear and relevant logics to provide logical accounts of static process structure, and combinations of relevance and modality to account also for dynamic behaviour. A general notion of model is introduced, based on which, three examples are given using Milner's synchronous process calculus SCCS. The structure of models is enriched by prefixing operators to cover also dynamic behaviour. Logically dynamic behaviour is captured by adding past and future modal operators. The resulting logic is given sound and complete axiomatlzations and shown to conservatively extend the positive fragment of linear logic. Finally the induced interpretations...

    jication on tracheal mucow velocity in dogs. J. Appl. Physiol. 39(2): 242-246. 1975.-The impairment of mucociliary transport by dry air breathing and the restoration of function with subsequent humidification of inspired air were investigated in anesthetized dogs. Tracheal mucous velocity was measured by a cinebroncho-fiberscopic technique. The breathing of dry air through an un-cuffed endotracheal tube produced almost complete cessation of the flow of tracheal mucus after 3 h. Subsequent breathing of air at 38°C with 100(iO relative humidity restored tracheal mucous velocity to control values by the end of an additional 3 h. Histo-logic examination of the trachea at...

    Abstract Soft-tissue and bone necrosis, although rare in childhood, occasionally occur in the course of infectious diseases, either viral or bacterial, and seem to be the result of hypoperfusion on a background of dissemi-nated intravascular coagulation. Treatment consists in correction of septic shock and control of necrosis. Ne-crosis, once started, shows extraordinarily rapid evolu-tion, leading to soft-tissue and bone destruction and resulting in anatomic, functional, psychological, and social handicaps. Ten mutilated children were treated from January 1986 to January 1999 in Hospital de Dona Estefânia, Lisbon, Portugal. One was recovering from hemolytic-uremic syndrome with a severe combined immunodeficiency, another malnourished,...

  16. Synthesizing advanced transaction models using the situation calculus. 2006. Submitted to the Journal of Intelligent Information Systems

    Iluju Kiringa; See Profile; Alfredo Gabaldon; Iluju Kiringa; Alfredo Gabaldon
    Abstract The situation calculus is a versatile logic for reasoning about actions and formalizing dynamic domains. Using the non-Markovian action theories for-mulated in the situation calculus, one can specify and reason about the effects of database actions under the constraints of the classical, flat database transactions, which constitute the state of the art in database systems. Classical transactions are characterized by the so-called ACID properties. With non-Markovian action theo-ries, one can also specify, reason about, and even synthesize various extensions of the flat transaction model, generally called advanced transaction models (ATMs). In this paper, we show how to use non-Markovian...

    model; transformation rule of resource type definition; transformation rule of imports resources; transformation rule of exports resources; transformation rule of role resources. Abstract. Software evolution process model (EPM) is created in terms of a formal evolution process at higher abstract level and is general while software process is concrete, so EPM must be instantiated before its enactment. The method to transform any EPM to its execution model based on logic programming is proposed. Since activity contains the imports resource, roles resource, exports resource and tasks, the rules to transform the four parts of activity level of any EPM to its...

    Industrial capitalism created major changes in society and in the demand for workforce through industrialization and urbanization. This greatly influenced on the movement of large number of workers in global proportions. But, it’s a question whether entering the European Union of state candidates will make the same move? With the entry of central European countries into the EU, Bulgarians, Romanians wandered into westward in a big number. Will the entry of Croatia, Montenegro, and Serbia into the EU cause the same situation? How will their social mobility be? Croatia has at least 20,000 qualified tourism workers for the next summer...

    BACKGROUND. Cancer of the corpus uteri occurs more commonly among white women in the U.S., yet survival is poorer for black women. This study examined whether this trend has changed and also examined the relation of age and histo-logic subtype to differences in stage. METHODS. This retrospective cohort study assessed incidence trends, mortality trends, and the relation of age and histologic subtype to stage for 12,079 incident cases and 2325 deaths registered between 1985 and 1994 in Michigan. Rate ratios compared incidence and mortality. Odds ratios quantified the contribution of age and histologic subtype to differences in risk for advanced...
