The Centrality and Development of Anschauung in Nietzsche's Epistemology
Authors: Jensen Anthony K. 
Published: December 2012

Abstract
This article traces the evolution of a single concept—Anschauung—in Nietzsche's thinking. It shows that Nietzsche relies to a great extent in his early epistemology on Schopenhauer's romantic notion of Anschauung as a way of apprehending timeless and universal ideas. After The Birth of Tragedy, Nietzsche begins to use the term to designate the mental process of transference by which stimulation becomes a choate representation. In a third phase of development, Nietzsche abandons any positive use of the term and employs Anschauung instead as a sarcastic watchword for essentialist epistemologies generally. Although it has been nearly ignored in anglophone literature, the changing context of its employment is an essential aspect of Nietzsche's development as a thinker.
A general stability criterion for switched linear systems having stable and unstable subsystems
Authors: Martín Jesús San , O'Farrell Anthony G. 
Published: December 2012

SUMMARYWe report conditions on a switching signal that guarantee that solutions of a switched linear system converge asymptotically to zero. These conditions apply to continuous, discrete‐time and hybrid switched linear systems, those having both stable subsystems and mixtures of stable and unstable subsystems.

Published: December 2012

AbstractCation exchange polymeric matrices are widely used in water treatment protocols to reduce the mineral content of hard waters, even for human consumption. However, they are not antibacterial and flowing bacteria can be trapped in their structures and proliferate, thus acting as microbial contamination sources. Here, Ag@Co‐nanoparticles (Ag@Co‐NPs) with a low‐cost superparamagnetic Co0‐core and an antibacterial Ag‐shell are synthesized on granulated cation exchange polymeric matrices under soft reaction conditions. The presence of these NPs provides the final nanocomposite (NC) with additional functionalities (superparamagnetism and antibacterial activity) making it ideal for water purification applications. Ag@Co‐NPs are synthesized in situ on four cation exchange polymeric matrices containing either strong (sulfonic) or weak (carboxylic) acid functional groups homogeneously distributed (C‐type) or concentrated on an external shell (SST‐type) by the intermatrix synthesis (IMS) method. The NCs are characterized (metal content, NP size and distribution, metal oxidative state, and metal release) and evaluated for water purification applications.
Gis analysis of patch use and group cohesiveness of bearded sakis (chiropotes sagulatus) in the upper essequibo conservation concession, guyana
Authors: Shaffer Christopher A. 
Published: December 2012

AbstractThis study examines how northern bearded sakis (Chiropotes sagulatus) in Guyana adjust group cohesiveness according to the distribution and quality of food patches. I introduce a GIS based method for quantifying food patch quality and how it relates to bearded saki group spread and group size. While the concept of food patch is central to most models of primate socioecology, defining what constitutes a patch has been notoriously problematic in primate studies. In addition, researchers have struggled to quantify group spread and group cohesiveness. Advances in spatial analysis software in the last decade now allow primate researchers to better quantify these variables. Group spread in bearded sakis was not significantly greater in lower quality patches and sakis were not more spread out during feeding than during other activities. However, the study group was significantly less spread out during social behavior. Bearded saki group size was significantly correlated with both monthly fruit abundance and patch quality. In fact, mean daily patch quality explained ∼40% of the variation in foraging party size. These results suggest that bearded sakis may rely on a highly fluid social structure to mitigate the effects of intragroup feeding competition while living in large groups. Sakis do not adjust group spread on a patch‐by‐patch basis but rather fission into smaller foraging parties when resources become scarce seasonally and patch quality is low. This study shows that GIS is a powerful tool for modeling the relationship between group cohesiveness and resource quality and distribution. Am J Phys Anthropol, 2013. © 2012 Wiley Periodicals, Inc.
Robust Exponential Stability and Stabilization of a Class of Nonlinear Stochastic Time‐Delay Systems
Authors: Li Yanjiang , Zhang Xian , Yuan Meng 
Published: December 2012

AbstractThis paper presents new exponential stability and delayed‐state‐feedback stabilization criteria for a class of nonlinear uncertain stochastic time‐delay systems. By choosing the delay fraction number as two, applying the Jensen inequality to every sub‐interval of the time delay interval and avoiding using any free weighting matrix, the method proposed can reduce the computational complexity and conservativeness of results. Based on Lyapunov stability theory, exponential stability and delayed‐state‐feedback stabilization conditions of nonlinear uncertain stochastic systems with the state delay are obtained. In the sequence, the delayed‐state‐feedback stabilization problem for a nonlinear uncertain stochastic time‐delay system is investigated and some sufficient conditions are given in the form of nonlinear inequalities. In order to solve the nonlinear problem, a cone complementarity linearization algorithm is offered. Mathematical and/or numerical comparisons between the proposed method and existing ones are demonstrated, which show the effectiveness and less conservativeness of the proposed method.
Dynamic Output Feedback Consensualization of Uncertain Swarm Systems with Time Delays
Authors: Xi Jianxiang , Shi Zongying , Liu Guangbin , Zhong Yisheng 
Published: December 2012

AbstractConsensus analysis and design problems of high‐dimensional discrete‐time swarm systems in directed networks with time delays and uncertainties are dealt with by using output information. Two subspaces are introduced, namely a consensus subspace and a complement consensus subspace. By projecting the state of a swarm system onto the two subspaces, a necessary and sufficient condition for consensus is presented, and based on different influences of time delays and uncertainties, an explicit expression of the consensus function is given which is very important in applications of swarm systems. A method to determine gain matrices of consensus protocols is proposed. Numerical simulations are presented to demonstrate theoretical results.

Published: December 2012

ABSTRACTA sensitive and rapid high‐performance liquid chromatography–tandem mass spectrometry (HPLC‐MS/MS) method has been developed and validated for the determination of gymnemagenin (GMG), a triterpene sapogenin from Gymnema sylvestre, in rat plasma using withaferin A as the internal standard (IS). Plasma samples were simply extracted using liquid–liquid extraction with tetra‐butyl methyl ether. Chromatographic separation was performed on Luna C18 column using gradient elution of water and methanol (with 0.1% formic acid and 0.3% ammonia) at a flow rate of 0.8 mL/min. GMG and IS were eluted at 4.64 and 4.36 min, ionized in negative and positive mode, respectively, and quantitatively estimated using multiple reaction monitoring (MRM) mode. Two MRM transitions were selected at m/z 505.70 → 455.5 and m/z 471.50 → 281.3 for GMG and IS, respectively. The assay was linear over the concentration range of 5.280–300.920 ng/mL. The mean plasma extraction recoveries for GMG and IS were found to be 80.92 ± 8.70 and 55.63 ± 0.76%, respectively. The method was successfully applied for the determination of pharmacokinetic parameters of GMG after oral administration of G. sylvestre extract. Copyright © 2012 John Wiley & Sons, Ltd.
Environmental Management Evolution: Empirical Evidence from Spain and Italy
Authors: Ormazabal M. , Sarriegi J.M. 
Published: December 2012

ABSTRACTThis research is focused on a survey conducted among Spanish and Italian companies in order to define the environmental management evolution within firms. Through this survey, a number of maturity stages were defined and validated, and the identification of the relevant factors for each of the maturity stages was made. Survey results show that companies start with environmental management issues due to legislation requirements. Afterwards, firms go through a training phase, continuing with the systematization stage, then look for economic benefits through ecological improvements (ECO2 stage) and finish with the eco‐innovation and leading green company stages. The survey has shown that the maturity stages have application in all types of industrial sector. These are useful for those firms that want to make progress in environmental matters, as it helps them to identify at which maturity stage they are and what are the factors that they need to take into account to move forward.

Outcomes of a modified approach to transcatheter closure of perimembranous ventricular septal defects
Authors: Landman Geri , Kipps Alaina , Moore Phillip , Teitel David , Meadows Jeffery 
Published: December 2012

ObjectivesTo describe the immediate and midterm results of a modified method for transcatheter closure of perimembranous ventricular septal defects (pmVSDs).BackgroundTranscatheter closure of pmVSDs has been associated with development of heart block due to impingement on the ventricular conduction system. Ventricular septal aneurysms (VSAs) are common; the VSA tissue can serve as a target for the device without necessitating direct contact with the conduction system.MethodsBetween 2004 and 2011, 15 patients underwent transcatheter closure of a pmVSD utilizing a device implanted into a VSA. Catheterization reports were examined in addition to pre‐closure, post‐closure, and current clinical, ECG, and echocardiographic data.ResultsThe median age was 20 years (4–61 years), and the most common indication for closure was increasing LV dilation. Four different Amplatzer devices were utilized. Following device implantation there was a decrease in Qp:Qs (1.7–1.1) and in RV:LV pressure ratio (0.36–0.31). There were no deaths, no device embolizations, and no new heart block or PR interval prolongation. Three patients developed a new right bundle branch block (RBBB). The median follow‐up time was 1.5 years (4 months to 7.1 years). Two patients required further procedures for important residual shunting. Six continued to have a “trivial/small” residual leak, but only one had any degree (mild) of residual LV dilation. None of the complications were significantly associated with age or weight at the time of procedure, original size of the VSD, or size or type of the device used.ConclusionTranscatheter closure of pmVSD with placement of the device into the VSA is safe and effective, and may result in fewer instances of atrioventricular block and valve abnormalities than have been reported with alternative methods of pmVSD device closure. Persistent VSDs and new RBBBs remain an important issue. © 2013 Wiley Periodicals, Inc.

Published: December 2012

SummaryThe number of providers in the cloud computing market is increasing at a rapid pace. They offer a wide range of pricing schemes, different types of instance, or even different value‐added features to differ from other competitors, making the cloud market more complex. Cloud brokering enable users to choose the best cloud provider for their needs and avoid particular providers' lock in. Moreover, the use of multiple clouds offers several benefits such as scalability of services, improvement in fault tolerance, or cost reduction. However, users still find difficult the decision of where to deploy their resources as they have to handle too much information. The use of cloud brokering mechanisms is useful to reduce the complexity of using a multi‐cloud environment. In this paper, we show a cloud broker architecture for deploying virtualized servers across available clouds. This architecture uses a scheduling module to obtain an optimal placement of a virtual infrastructure while making it transparent for users. We focus our investigation on dynamic cloud scenarios in terms of variable resource prices, taking into account the virtual machine migration overhead issue. We evaluate the performance of several use cases applied in real scenarios, and we show the improvement potential of using brokering mechanisms in dynamic deployments compared with static ones.
