A Developmental/Integrative Perspective of the Recent Traumatic Episode Protocol
Authors: Laub Brurit , Weiner Nomi
Published: July 2011

The recent traumatic episode protocol (R-TEP) is an adaptation of the eye movement desensitization reprocessing (EMDR) standard protocol to the acute phases following trauma. In this article, the R-TEP structure and procedures were analyzed from a developmental/integrative perspective. It is proposed that the therapist’s developmental understanding and attunement can enhance the therapeutic dyad and can promote flexible decision making while using the R-TEP procedures. One case illustration of a recent trauma intervention demonstrates the advantage of developmental attunement in using the R-TEP. This perspective enables the therapist to pace the various styles of processing as they relate to the different stages of the memory consolidation process.
The Role of Employment Protection during an Exogenous Shock to an Economy
Authors: Malul Miki , Rosenboim Mosi , Shavit Tal , Tarba Shlomo Yedidia
Published: July 2011

This paper explores the role of employment protection when powerful external crises reduce demand for products. We first present a theoretical framework that shows that employment protection has a U-shaped effect on abnormal unemployment during a negative exogenous shock to an economy. Using data from the 33 OECD countries, we analyze how the level of employment protection affected the stability of unemployment rates during the recent global economic crisis. The results suggest that countries with an intermediate level of employment protection will have more stable unemployment rates during a world crisis. The policy implication of our paper is that countries should seek a medium level of employment protection that may act as an automatic stabilizer of the economy on the macro level.
Hydrodynamic Investigation in an Annular Reactor with Mixing Time and Residence Time Distribution: Flow Rates Estimation with the Gauss-Newton Gradient Technique
Authors: Rjeb Skandar , Hannachi Ahmed , Abdelhamid Ratal
Published: July 2011

In this work, flow patterns within an annular chemical reactor were characterized. The reactor was modeled by a cascade of communicating Continuous Stirred Tank Reactors (CSTRs) exchanging flow rates of variable intensities. Mixing time and Residence Time Distribution measurements were used as basis for flow modeling. A Matlab computer code has been developed to predict the exchanged flow rates through the minimization of an objective function. This paper describes the parameter estimation technique which is based on the Gauss-Newton method with a linear search algorithm. Only two opposite flow rates between reactor compartments were assumed and were identified for various mixing conditions. For the studied cases, the predicted responses were close to the experimental measurements.

Educational Possibilities of the Project Colour Visualization of Music

We propose a system of colour visualization of music based on a system of colour signs, which are connected to musical tones. Tones, which are in harmonic relationships, are represented by related colours. First, we outline the foundations on which the system of colour signs is based - the mathematical model of harmony. We discuss several possibilities of visual representation of expressive elements of music - melody, composition, rhythm and harmony. These relationships enabled us to develop a computer program that employs these elements for visualization. The program mimics human perception in which the parts are determined by the perception of the whole. Furthermore, the program enables the development of tools that can enhance music understanding during listening or performing. Music performance can acquire a new quality with the use of interactive coloured musical instruments, which by using colours show the performer different possibilities for forming musical harmonies and thereby change the composing of music into a game and attractive colour-aural journey. Here we stumble upon a challenge for educational science and methodology: how to use such upcoming multimedia tools. These tools would bring the processes of learning and playing a game closer together since playing games is a child's most natural form of functioning. Furthermore, in the area of artistic creation we can once again establish a balance between our logical and intuitive nature.

Measurement of Three-Dimensional Magnetostriction on Grain-Oriented Electrical Steel Sheet

This paper deals with the magnetostriction of a grain-oriented electrical steel sheet measured by using the two-dimensional vector magnetic property measurement system and a three-axial strain gage. The magnetostrictions in arbitrary direction are calculated with the measured strain tensors. The magnetostriction characteristics were changed depending on the magnetization process according to the exciting magnetic flux density and the exciting direction. In this paper, we make clear the relationship among the two-dimensional magnetostriction, the magnetic flux density vector, and the magnetic field intensity vector in the grain-oriented electrical steel sheet.

The incidence of zooplankton speed and sampling depth on the sampling efficiency. Preliminary comparative data

The efficiency of the tubes, traps and nets is varying according to the type of the studied lake and the type of applied methodology. Thus, from one study to another, the obtained data can vary within certain limits for the same water body and season. The inherent variability led to some correlation studies between used methodologies in order to corroborate the results and render them comparable. The present study is referring to the comparative analysis of the efficiency of the tubes used for the sampling of the superficial layers in the stagnant water bodies. The Limnos and Green tubes have been compared to sampling tubes of different diameters. The water speed at the entrance in the tube is calculated and compared with the swimming speed of cladocerans (Simocephalus vetulus juveniles and adult individuals) and copepods (Cyclops sp. juveniles and adult individuals). It is demonstrated that the diameter of the tube used for sampling influences the sampling efficiency especially for the zooplankton species that are actively swimming in the water body. The present study sets the basis for a larger methodology study that, by integrating statistical analysis and hydrodynamics would establish an unified methodology for limnologists worldwide.
Néron Models of Green–Griffiths–Kerr and log Néron Models
Authors: Hayama Tatsuki
Published: July 2011

For a variation of Hodge structure over a punctured disk, Green, Griffiths and Kerr introduced a Néeron model which is a Hausdorff space that includes values of admissible normal functions. On the other hand, Kato, Nakayama and Usui introduced a Néron model as a logarithmic manifold using log mixed Hodge theory. This work constructs a homeomorphism between these two models.
Routine preoperative electrocardiogram in patients over 40 years of age: a hearty need or a customary practice?
Authors: Ghimire A , Rahman TR , Bhattarai B , Koirala S , Khatiwada S , Dhital D
Published: July 2011

Background: Preoperative 12-lead electrocardiogram (ECG) can provide important information on the state of the patient’s myocardium and coronary circulation. Routine screening ECG preoperatively in all adult patients seems cumbersome and unnecessary. Objectives: To find out the incidence of ECG abnormality of patients above 40 years of age presenting in the preanaesthetic check up (PAC) clinic and to observe any associated co-morbid conditions. Methods: This is a prospective observational study done in the PAC clinic of the department of Anaesthesiology and Critical Care, at B. P. Koirala Institute of Health Sciences, Dharan from June2010 to August 2010 over a period 3 months. The study enrolled 360 patients aged 40 years and above. Laboratory investigations such as hemoglobin, blood grouping, urine routine and microscopic examinations along with biochemical parameters like blood urea, serum creatinine, fasting and post prandial blood sugar were reviewed. A 12-lead ECG was obtained for all patients included in the study. Results: Out of 360 patients, 168 were male and 192 female. Abnormal ECG was observed in 38 (10.5%) patients. Frequency of abnormal ECG increased with increasing age. Diabetic, hypertensive and smokers had higher incidence of abnormal ECG. Conclusion: A preoperative screening ECG for all adult patients aged 40 years visiting PAC clinic is relevant and desirable for risk- stratification.

Another (Food) World Is Possible
Authors: Heller Chaia
Published: July 2011

If the post-war industrial model entails a mix of technological and chemical interventions that increase farm productivity, then post-industrial agriculture (emerging in the 1970s) constitutes agricultural surpluses, as well as an array of trade, aid and biotechnology practices that introduce novel foodstuffs (processed and genetically modified) on an unprecedented scale. While industrial agriculture reduces the farming population, the latter gives rise to new sets of actors who question the nature and validity of the industrial model. This essay explores the rise of one set of such actors. Paysans (peasants) from France's second largest union, the Confederation Paysanne, challenge the industrial model's instrumental rationality of agriculture. Reframing food questions in terms of food sovereignty, paysans propose a solidarity-based production rationality which gives hope to those who believe that another post-industrial food system is possible.

Per un nuovo corpus dei decreta decurionum delle città romane d'Italia e delle province occidentali
Authors: Parma Aniello
Published: July 2011

The author sets out a work in progress : a new critical edition of the decreta decurionum in Italy and in the western provinces during the four centuries of the imperial era. A new collection of the evidence was needed : the previous work of Sherk (1970) is incomplete and out of date. The new corpus includes about a hundred of inscriptions (35 p. c. more than Sherk) : for every text an historical and juridical commentary is given, photographs and an index of Latin and Greek lemmas in context.These inscriptions are reliable pieces of first-hand evidence upon the administration of Roman cities. In some cases they inform us of proceedings and competences we did not know at all or only in a very general way.
L’évolution du monnayage de Ptolémée Ier et les événements militaires (c. 323-c. 300)
Authors: Rodriguez Philippe
Published: July 2011

Sans délaisser les aspects politiques du monnayage de Ptolémée Ier, les historiens ont analysé les évolutions iconographies et pondérales de ce monnayage en termes financiers. La politique monétaire de Ptolémée, dans un premier temps, est avant tout un instrument d’affirmation de l’indépendance politique de l’Égypte. Toutefois, à cet acte fondateur succèdent une série de réformes qui semblent plus pragmatiques et qui sont un écho à la position stratégique de Ptolémée au sein du concert international en Méditerranée orientale. Si l’évolution du monnayage est confrontée au domaine militaire, l’analyse conduit à trois conclusions. Ptolémée, pendant vingt ans, a augmenté sa puissance militaire, malgré le grave recul de 306. Les changements iconographiques ont précédé l’allégement de l’étalon, tandis qu’au moment de l’allége- ment de l’étalon, l’iconographie ne varie pas. Le changement iconographique s’opère lorsque la qualité du monnayage n’est pas altérée. Quand le poids est altéré, l’iconographie persiste et sauvegarde la continuité du monnayage lagide et la confiance de l’utilisateur. Les mutations iconographiques correspondent à un programme politique et apparaissent plutôt comme un signe positif, tandis que les mutations de poids semblent, elles, des mesures financières et dénotent une situation politique plus délicate pour Ptolémée.
Images et damnatio memoriae
Authors: Huet Valérie
Published: July 2011

La question des images et de la damnatio memoriae a été récemment fortement explorée et renouvelée par les historiens d’art britanniques, américains et germaniques, et presque entièrement ignorée par les Français. L’article précise les pistes suivies par ces chercheurs, et énonce certains problèmes méthodologiques qui y sont inhérents. Dans toutes les opérations de condamnation d’une personne, une seule était systématiquement en vigueur, celle concernant les portraits, l’effacement du visage. Celui-ci pouvait revêtir plusieurs aspects: une mutilation, une transformation («palimpseste sculpté» ou substitution) et une mise en dépôt. Pour appréhender leur importance et leur signification profonde, il faut les replacer dans l’ensemble des transformations que subissent les monuments dans le monde romain, en considérant d’une part la question des spolia, d’autre part les jeux de tête et de décapitation permanents des statues, que le personnage ait laissé de bons souvenirs ou qu’il ait été condamné.

Identité militaire et avancement au centurionat dans les castra peregrina
Authors: Cosme Pierre , Faure Patrice
Published: July 2011

L’épitaphe répertoriée au CIL, VI, 3328 attire l’attention par une formule originale précisant que le défunt – Marcus Orbius – est mort cinquante et un jours avant de devenir centurion. Ce document nous a paru aussi propice à une réflexion plus générale sur le sens des termes frumentarii et peregrini attribués aux soldats cantonnés dans les castra peregrina à Rome dont faisait partie Marcus Orbius et sur les étapes essentielles de l’avancement au centurionat. Les appellations frumentarii et peregrini paraissent révélatrices des processus d’identification des différents corps de troupes. Frumentarii et peregrini semble en effet s’être dééfinis dans une double opposition: d’une part face aux légionnaires des provinces qui ne recevaient pas le blé gratuit, d’autre part face aux soldats de la garnison urbaine et aux habitants de l’Vrbs qui les considéraient comme des provinciaux.
Les clauses « sans précédents » de la Lex de imperio Vespasiani. Une interprétation juridique
Authors: Mantovani Dario
Published: July 2011

Dans la Lex de imperio Vespasiani, on remarque l’alternance entre des clauses qui, dans l’acte d’attribuer des pouvoirs à Vespasien, se reportent à des prérogatives identiques dont bénéficiaient les principes précédents (ch. I, II, V, VI; cf. VII) et des clauses qui, au contraire, ne parlent pas de prédécesseurs (ch. III, IV, VIII). L’étude propose une explication de ce phénomène. Il ne faut pas lire, dans l’absence ou la présence de précédents, l’histoire ou même la chronologie des prérogatives du princeps au cours du Ier siècle apr. J.-C. Il s’agit, au contraire d’une différence juridique, entre «actes» et «effets», entre l’attribution du pouvoir d’accomplir un acte (conforme aux précédents) et la légalisation des effets de l’acte. Les clauses qui mentionnent les

principes précédents attribuent des pouvoirs (de conclure des foedera, de senatum habere, de proferre pomerium, d’agere ex usu reipublicae) et renvoient aux mêmes pouvoirs possédés par les principes

précédents. Les trois clauses sans précédents ont pour but de régler au niveau législatif les effets des actes du princeps: dans les capita III et VIII, la Lex de imperio Vespasiani établit que ces actes sont valides comme s’ils étaient accomplis selon les lois; dans le caput IV, elle établit - selon l’interprétation qui semble préférable - que l’on déroge aux conditions requises pour l’électorat passif établies par les lois annales.
Les patrimoines fonciers des sénateurs dans l’Italie républicaine : l’apport des sources épigraphiques
Authors: Berrendonner Clara
Published: July 2011

The studies devoted to senatorial property during the Republic have shown, on the basis of the litterary sources, the creation of a gap between two fortune levels in the 1st century BC. The epigraphic documentation confirms this evolution. It is possible to identify senatorial properties through five criteria: the name of the fundus; a local magistrature (the Tarent law requires from a magistrate to be proprietor in the city); an epitaph located on a rural estate; an honorific inscription brought to light in a city where a senator was proprietor; slaves or freedmen who give the cognomen of their senatorial owner. The catalogue of Republican senatorial properties reveals that the senators who held provincial commands possessed fundi in Latium and Campania. On the contrary, recent senators were proprietors in peripherical zones. These senators were introduced into the curia by the imperatores, and some of them made profit on the Sullanian proscriptions. Few were able to escape the Civil Wars, and to hand down their properties to their heirs.
Prodigien aus Italien : geographische Verteilung und religiöse Kommunikation
Authors: Rosenberger Veit
Published: July 2011

Die meisten Orte, in denen sich Prodigien ereigneten, gehörten seit der Mitte des 4. Jahrhunderts v. Chr. zum ager Romanus und befinden sich auf einem etwa 50 km breiten, von Nordwesten nach Südosten verlaufenden Streifen, der wenige Kilometer nördlich von Rom etwa bei Caere beginnt und auf der Höhe von Capua endet. Dabei zeigt sich, daß die Mehrzahl der Städte mit Prodigienmeldungen an den großen viae publicae liegt, vor allem an der via Appia

und an der via Latina. Rom kommunizierte durch Prodigien vor allem mit seinen Bürgern außerhalb der Stadt, nicht mit den Bundesgenossen. Daher ist die Bedeutung der Prodigienmeldungen aus den Städten Italiens vor dem Bundesgenossenkrieg als Gradmesser für die Loyalität zu Rom, wie von Bruce MacBain postuliert, zu revidieren.

Effects of TheraMax on Influenza Virus Infections in Cell Culture and in Mice
Authors: Smee Donald F , Hurst Brett L , Wong Min-Hui
Published: July 2011

Background:

Limited in vivo studies in the scientific literature suggest that components of green tea and elderberry may be beneficial in treating influenza virus infections. They are thought to act by blocking virus adsorption to cells. TheraMax® is a proprietary medication administered by nasal spray that contains both green tea and elderberry extracts that was evaluated for antiviral activity.

Methods:

TheraMax was tested by dilution in Madin–Darby canine kidney cell cultures in standard viral cytopathic effect (CPE) inhibition and virucidal assays against eight influenza A and B strains. It was also administered intranasally to mice to determine protective activity compared to oral oseltamivir against an influenza A/NWS/33 (H1N1) infection.

Results:

In cell culture assays, TheraMax was found to inhibit viral CPE by 50% at a 1:20 dilution for seven of the eight virus strains, with no virucidal activity at 1:2 dilution. The undiluted product was administered to anaesthetized mice twice daily for 4 days starting 2 h before or 12 h after infection. Alternatively, TheraMax and virus were combined for treatment and infection. Oseltamivir was given orally twice daily for 5 days at 10 mg/kg/day starting at −2 h. TheraMax (combined directly with virus) and oseltamivir each prevented death and curtailed weight loss during the infection, and improved lung haemorrhage scores on day 6. TheraMax starting at −2 h or 12 h significantly delayed death by >2 days and reduced lung haemorrhage scores, but most animals died.

Conclusions:

These combined results indicate that TheraMax delayed symptoms during animal infections, likely through blocking of virus adsorption.
Distinguishing colour variants of Serapias perez-chiscanoi (Orchidaceae) from related taxa on the Iberian Peninsula
Authors: Venhuis Caspar , Oostermeijer J. Gerard B.
Published: July 2011

Serapias perez-chiscanoi has a stable and uniform appearance with green flowers. Throughout its distribution area, however, plants have been found with deviant pink to red flowers that show similarities with other taxa that are occasionally pale flowered. S. perez-chiscanoi is easy to differentiate from S. cordigera subsp. cordigera by the colour of the flowers (S. cordigera subsp. cordigera has red to purple flowers) and the fact that the hypochile dimensions of S. perez-chiscanoi are significantly smaller. It is, however, more difficult to distinguish it from individuals of S. cordigera subsp. gentilii with pale flowers, which occur frequently. The two taxa differ in colour pattern and floral dimensions, especially the hypochile length, which is shorter in S. perez-chiscanoi. Pale-flowered individuals of another species, S. parviflora, are easily distinguished by their significantly smaller flowers. S. perez-chiscanoi occurs in Spain in the autonomous regions of Extremadura and Castilla-La Mancha and in Portugal, S. cordigera subsp. gentilii seems to occur along the coastal regions of SW Portugal, while S. cordigera subsp. cordigera and S. parviflora are distributed throughout the Iberian Peninsula.
Integrating Project Management, Product Design with Industry Sponsored Projects provides Stimulating Senior Capstone Experiences
Authors: Sanger Phillip A.
Published: July 2011

Abstract ¾ Many students are uncomfortable with real world engineering problems where needs and requirements must be concretely defined and the selection of design solutions is not black and white. This paper describes a two semester, multi-disciplinary senior capstone project for students from three Engineering and Technology Department programs (electrical engineering, electrical and computer engineering technology, and engineering technology) that brings together the tools of project management and the creative product development process into industry sponsored projects.  The projects are fully integrated with the Center for Rapid Product Realization with its dual goals of economic development and enhanced learning.  The stage/gate development process is used with six formal reviews covering the development of the proposal through to the fabrication and testing of the project’s output.  Over the past four years thirty five (35) projects have been undertaken with students getting an exciting authentic life experience and introducing them to the real world of engineering.
Uma abordagem de geomarketing do esporte
Authors: Ravenel Loïc
Published: July 2011

Este artigo apresenta, a partir de um ponto de vista conceitual e funcional, a contribuição de uma abordagem de geomarketing para a análise do esporte. Além de um conluio entre a geografia e o marketing, esse recorte implica primeiramente uma fase de decisão operacional para a progressão da atividade esportiva. Se os seus métodos se inspiram muito na análise espacial e na geomática, e se inscrevem em uma perspectiva estruturalista, o interesse do geomarketing não deve se limitar ao estudo de mercado nem à cartografia dos clientes ou dos potenciais clientes nas zonas de compra: trata-se de não ficar apenas na representação espacial de dados para enfocar a integração da dimensão geográfica na estratégia de marketing. Esta integração nos leva a uma visão mais sistemática que utiliza o marketing como um modelo de análise dos serviços esportivos, serviços pelos quais as escolhas dos usuários ou dos consumidores tornaram-se preponderantes. Após ter colocado as pesquisas em geografia dos esportes no seu contexto científico, uma definição de geomarketing é proposta, insistindo sobre a especificidade dos serviços esportivos. Três grandes domínios de intervenções são identificados como pistas de trabalho que combinam as esperas dos atores com as novas perspectivas geográficas.

Lossless Data Embedding in BTC Codes Based on Prediction and Histogram Shifting
Authors: Hong Wien , Chen Tung Shou , Shiu Chih Wei , Wu Mei Chen
Published: July 2011

This paper proposes a lossless data embedding method for Block Truncation Coding (BTC) compressed images based on prediction and histogram shifting techniques. Because BTC is easy to implement, and requires significantly less CPU cost, it has arouse widely attention in applications where real-time processing is demanded. For the existing lossless data embedding method in BTC codes, the decoder has to be specifically designed so that the spatial domain image can perfectly reconstructed from the compressed codes. Therefore, the application of these methods is limited. In the proposed embedding method, we slightly modified the quantization values of BCT codes to embed data losslessly, and a standard BTC decoder can be used to decode the BTC codes. The embedded secret messages can be extracted at the receiver side with the correct key. The experimental results revealed that the proposed method not only recovers the stego image to its original one, but also preserved a high image quality.

Application of WAVELET-SVM in Fault Diagnosis for the UV Control System
Authors: Wang Sheng Wu , Shi Xiu Hua , Xu Hui , Tong Zhao Jing
Published: July 2011

Wavelet Analysis extracts the main feature from the fault signal through wavelet transformation, so it is advantageous to withdraw fault characteristic for fault diagnosis. Support Vector Machine (SVM) has shown its good classification performance in fault diagnosis. A new method of fault diagnosis for UV control system based on WAVELET-SVM is raised. The sensor output is sampled in frequency domain and it is preprocessed by wavelet to extract main vectors of the fault features. Fault patterns under various states are classified using multi-class SVM, and fault diagnosis is realized. The simulation results show that WAVELET-SVM is feasible to detect and locate faults quickly and exactly and has high robustness.
Structure of Mixture Kernel Function and its Application in Soft Measurement about Beating Degree
Authors: Tang Wei , Zhao Yan Zi
Published: July 2011

Kernel function is dominant in regression process of Support Vector Machine (SVM), it influences the prediction performance of SVM directly. Single local or global kernel function has limitation in generalization or learning capacity. The mixture kernel function with two good capacities had been structured, and it had been used in soft-sensor modeling of refining process. The contrast of simulation results show: the generalization ability of SVM based on mixture kernel function is better than the ones based on the single local or global kernel function, the algorithm had been applied in the refining process of HETAO wood industry factory, and the prediction result meets the requirement of craft production.

Non-Probabilistic Structural Reliability Model Based on Ellipsoidal-Bound Model with Nonlinear Expansion
Authors: Li Kun Feng , Yang Zi Chun , Sun Wen Cai
Published: July 2011

Info-gap model is the foundation of the non-probabilistic reliability model. In this paper, ellipsoidal-bound model which is the most common Info-gap model has been updated by acquiring restriction information about uncertain quantities. The initial ellipsoidal-bound model can be degenerated from the updated model. A non-probabilistic structural reliability model based on the updated ellipsoidal-bound model was established. A non-probabilistic reliability index was proposed and the calculation method was also given. The example shows that the introduction of restriction information is valid, and the new non-probabilistic reliability model can reveal the influence of the span restriction of uncertain quantities on structural reliability.

Authors: Liu Yan , Shen Xiao Dong
Published: July 2011

The purpose of this paper is to classify objects contained in images by the object categories. A new object feature in computer vision is introduced, that is fractional histograms of oriented gradients (fHoG). Due to the characteristics of fractional calculus, it is a descriptor that represents not only the object shape information but also the object texture details information. Together with pyramid decomposition, the fHoG features could be used to classify objects with similar shape but in different categories. For fHoG feature is some kind of local features, pyramid decomposition is designed to capture the hiding corresponding information between pixels. The two pyramid, spatial pyramid and Laplace pyramid, are both introduced. The former one is easy to compute while the calculation cost increasing fast as the pyramid level increasing. The latter one could save the calculation cost and get a better classification effect. Both of them could significantly improves the classification performance.
