The aim of this work was to compare experimental investigations on effects of lidocaine, calcium and, BRL 34915 on reentries to simulated data obtained by use of a model of propagation based on the Huygens' constriction method already described in previous works. Calcium and lidocaine effects are investigated on anisotropic conduction conditions. In both cases, reduction in conduction velocities are observed. In lidocaine case, a refractory area is located along the longitudinal axis. In agreement with experimental electrical mapping, the simulations (...) show that the stabilization of reentrant excitation is mainly due to the existence of this refractory area around which the reentrant circuit can develop. The experimental study shows that BRL 34915 has both arrhythmogenic and antiarrhythmic effects. A detailed electrophysiological analysis has shown that drug infusion act on normal cardiac cells by decreasing the relative and absolute refractory period. BRL 34915 action is simulated by a decrease in the refractory period showing that the time frequency of the reentrant activity is increased and that the spatial size where the reentry is developing is becoming smaller. These two effects are arrhythmogenic, the simulated data being so in good agreement with the experimental ones. (shrink)

The excessive and unsustainable exploitation of our marine resources has led to the promotion of marine reserves as a fisheries management tool. Marine reserves, areas in which fishing is restricted or prohibited, can offer opportunities for the recovery of exploited stock and fishery enhancement. This study examines the impact of the creation of marine protected areas, from both economic and biological perspectives. The consequences of reserve establishment on the long-run equilibrium fish biomass and fishery catch levels are evaluated. We include (...) reserve size as control variable to maximize catch at equilibrium. A continuous time model is used to simulate the effects of reserve size on fishing catch. Fish movements between the sites is assumed to take place at a faster time scale than the variation of the stock and the change of the fleet size. We take advantage of these two time scales to derive a reduced model governing the dynamics of the total fish stock and the fishing effort. Simulation results suggest that the establishment of a protected marine reserve will always lead to an increase in total fish biomass, an optimal size of a marine reserve can achieve to maximize the catch at equilibrium.

We generally agree with Burt's thesis. However, we note that the author did not discuss epigenetics, the study of how the environment can alter gene structure and function. Given epigenetic mechanisms, the utility of polygenic risk scores (PRS) is limited in studies of development and mental illness. Finally, in this commentary we expand upon the risks of reliance upon PRSs.

This work presents a specific stock-effort dynamical model. The stocks correspond to two populations of fish moving and growing between two fishery zones. They are harvested by two different fleets. The effort represents the number of fishing boats of the two fleets that operate in the two fishing zones. The bioeconomical model is a set of four ODE's governing the fishing efforts and the stocks in the two fishing areas. Furthermore, the migration of the fish between the two patches is (...) assumed to be faster than the growth of the harvested stock. The displacement of the fleets is also faster than the variation in the number of fishing boats resulting from the investment of the fishing income. So, there are two time scales: a fast one corresponding to the migration between the two patches, and a slow time scale corresponding to growth. We use aggregation methods that allow us to reduce the dimension of the model and to obtain an aggregated model for the total fishing effort and fish stock of the two fishing zones. The mathematical analysis of the model is shown. Under some conditions, we obtain a stable equilibrium, which is a desired situation, as it leads to a sustainable harvesting equilibrium, keeping the stock at exploitable densities. (shrink)

Spatial and temporal heterogeneity are often described as important factors having a strong impact on biodiversity. The effect of heterogeneity is in most cases analyzed by the response of biotic interactions such as competition of predation. It may also modify intrinsic population properties such as growth rate. Most of the studies are theoretic since it is often difficult to manipulate spatial heterogeneity in practice. Despite the large number of studies dealing with this topics, it is still difficult to understand how (...) the heterogeneity affects populations dynamics. On the basis of a very simple model, this paper aims to explicitly provide a simple mechanism which can explain why spatial heterogeneity may be a favorable factor for production. We consider a two patch model and a logistic growth is assumed on each patch. A general condition on the migration rates and the local subpopulation growth rates is provided under which the total carrying capacity is higher than the sum of the local carrying capacities, which is not intuitive. As we illustrate, this result is robust under stochastic perturbations. (shrink)

The balance between births and deaths in an age-structured population is strongly influenced by the spatial distribution of sub-populations. Our aim was to describe the demographic process of a fish population in an hierarchical dendritic river network, by taking into account the possible movements of individuals. We tried also to quantify the effect of river network changes (damming or channelling) on the global fish population dynamics. The Salmo trutta life pattern was taken as an example for.We proposed a model which (...) includes the demographic and the migration processes, considering migration fast compared to demography. The population was divided into three age-classes and subdivided into fifteen spatial patches, thus having 45 state variables. Both processes were described by means of constant transfer coefficients, so we were dealing with a linear system of difference equations. The discrete case of the variable aggregation method allowed the study of the system through the dominant elements of a much simpler linear system with only three global variables: the total number of individuals in each age-class.

Ventricular Fibrillation is responsible for a majority of sudden cardiac death, but little is known about how ventricular tachycardia (VT) degenerates into ventricular fibrillation. Several clinical studies focused only on preventing VT with a class III antiarrhythmic drug resulted in many deaths. Our simulations investigate the interactions between an antiarrhythmic drug likely to suppress a VT and a Figure 8 reentry. A parameter AAR is introduced to increase the action potential duration and therefore simulate various Class III drugs. Simulations are (...) ran under several conditions (phases of the reentry, values of AAR, durations). They show that a VT can be suppressed whatever the phase of the reentry but it strongly depends on the duration of the effect. It confirms that a drug which can suppress a reentry can also worsen it. It also shows a great variety of activation patterns and thus the complexity of antiarrhythmic drugs effects. Simulations also demonstrate that suppressing VT is an increasing function of AAR.

In this work we deal with a general class of spatially distributed periodic SIS epidemic models with two time scales. We let susceptible and infected individuals migrate between patches with periodic time dependent migration rates. The existence of two time scales in the system allows to describe certain features of the asymptotic behavior of its solutions with the help of a less dimensional, aggregated, system. We derive global reproduction numbers governing the general spatially distributed nonautonomous system through the aggregated system. (...) We apply this result when the mass action law and the frequency dependent transmission law are considered. Comparing these global reproductive numbers to their non spatially distributed counterparts yields the following: adequate periodic migration rates allow global persistence or eradication of epidemics where locally, in absence of migrations, the contrary is expected.

We used computer simulations to study the possible role of the dispersion of cellular coupling, refractoriness or both, in the mechanisms underlying cardiac arrhythmias. Local ischemia was first assumed to induce cell to cell dispersion of the coupling resistance (Case 1), refractory period (Case 2), or both of them (Case 3). Our numerical experiments based on the van Capelle and Durrer model showed that vortices could not be induced by cell to cell variations. With cellular properties dispersed in a patchy (...) way within the ischemic zone, a single activation wave could give rise to abnormal activities. This demonstrates the stability of the wave front under small inhomogeneities. Probabilities of reentry, estimated for the three cases cited above showed that a severe alteration of the coupling resistance may be an important factor in the genesis of reentry. Moreover, use of isochronal maps revealed that vortices were both stable and sustained with an alteration of the coupling alone or combined with a reduction of the action potential duration. Conversely, simulations with reduction of the refractoriness alone, inducing only transient patterns, could exhibit functionally determined reentries. (shrink)

We consider a two-patch epidemiological system where individuals can move from one patch to another, and local interactions between the individuals within a patch are governed by the classical SIRS model. When the time-scale associated with migration is much smaller than the time-scale associated with infection, aggregation methods can be used to simplify the initial complete model formulated as a system of ordinary differential equations. Analysis of the aggregated model then shows that the two-patch basic reproduction rate is smaller than (...) the 1 patch one. We extend this result to a linear chain of P patches . These results are illustrated by some examples for which numerical integration of the system of ordinary differential equations is performed. Simulations of an individual based model implemented with a multi-agent system are also carried out. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Vetera Novis Augere et Perficere:Thomas Aquinas and Christian-Muslim DialogueJoseph Ellul, O.P.Pope Leo XIII's encyclical letter Aeterni Patris, issued on August 4, 1879, sought to address many issues that were challenging nineteenth-century Catholic scholarship and academic life. In proposing the thought of Thomas Aquinas as a model of Catholic teaching, the Pope intended, in his own words, "to strengthen and complete the old by aid of the new,"1 not only (...) by reviving the study of the works and teachings of the Angelic Doctor, especially in the realm of philosophy, but also to uphold as perennial his method of engaging with his contemporaries within and without the Catholic faith.2 It is within this context that we are called upon to reflect upon this appeal: "vetera novis augere et perficere."The thirteenth century was indeed a time of intellectual upheaval, following the introduction of Aristotle and, later on, the translations into Latin of the Arabic commentaries on Aristotle by Ibn Rušd (Lat. Averröes; d. 1198). This event was met within the ecclesiastical world with apprehension, if not outright fear. Neo-Platonic philosophy and its interpretation by Ibn Sina (Lat. Avicenna; d. 1037) was already perfectly acceptable to Mediaeval Christian scholars. The latter was in fact considered an essential tool for understanding the illuminationist thought of St. Augustine. Étienne Gilson even spoke of Augustinisme avicennisant (Avicennized [End Page 1231] Augustinianism).3 The problem was Aristotle and his renowned commentator Ibn Rušd: a pagan commented on by an infidel.One must also note, however, that mediaeval Western intellectuals and institutions were able to encounter and adapt the Islamic legacy, because they already possessed a sufficient scientific base (with of course the contribution of translations of Greek together with Latin works) with which to understand, assimilate, and build upon this new knowledge that appeared from the East. In sum, mediaeval Christendom created living, vibrant societies, constantly searching, always discovering something new.In dealing with the specific (and delicate) subject of Aquinas's dialogue with Islamic thought, it would be necessary to reflect in particular upon two key works of his: the Liber de Veritate Catholicae Fidei contra Errores Infidelium (A Book on the Truth of the Catholic Faith against the Errors of Unbelievers),4 popularly known as the Summa contra gentiles [SCG], together with his De rationibus fidei contra Saracenos, Gnæcos et Armenos ad Cantorem Antiochenum, better known simply as De rationibus fidei.At this point it would be necessary to articulate the term "Islamic thought." Of itself it should not be identified with Islam as a religion. Rather, it should be considered as embracing classical Greek philosophy as interpreted by the Neo-Platonic movement and disseminated through Oriental Christian and Jewish schools of thought. Islamic civilization absorbed these teachings and built its own proper ediice upon these foundations.A Model for Interreligious Dialogue?Proposing Thomas Aquinas as a model for engagement with Islamic thought may also raise a few eyebrows. Hence, it would be appropriate to pose an essential question: "What type of dialogue existed in mediaeval times?" One should begin with an a priori exclusion of dialogue as it is understood today, given the fact that there existed neither the motive nor the means to implement it.In fact mediaeval society was aware of only three religions: the pagan, which had been replaced by Christianity; the Jewish, founded upon the precepts of the First Covenant which "Christ fulilled by his actions and [End Page 1232] by his teaching"5 and which was also believed to prefigure the everlasting New Covenant sealed by Jesus on the Cross; and finally, the Christian, which believed in Jesus as the final revelation of God to humanity.6 With such a vision in mind it is obvious that any doctrine that is not situated within these parameters, or which proposes some form of belief or conduct which was different from, if not contrary to, the Christian vision of God, the cosmos, and society, would be considered as heretical and its promoter an impostor.7When Islam made its appearance in the Christian world, it carried with it a book that it considered of divine provenance, and...

The importance of ethical consumerism to many companies worldwide has increased dramatically in recent years. Ethical consumerism encompasses the importance of non-traditional and social components of a company's products and business process to strategic success - such as environmental protectionism, child labor practices and so on. The present paper utilizes a random utility theoretic experimental design to provide estimates of the relative value selected consumers place on the social features of products.

Nearly all studies of consumers’ willingness to engage in ethical or socially responsible purchasing behavior is based on unconstrained survey response methods. In the present article we ask the question of how well does asking consumers the extent to which they care about a specific social or ethical issue relate to how they would behave in a more constrained environment where there is no socially acceptable response. The results of a comparison between traditional survey questions of “intention to purchase” and (...) estimates of individuals willingness-to-pay for social attributes in products reveal that simple survey questions are too “noisy” to provide operationally meaningful information and overstate intentions to a considerable extent.

This study uses best–worst scaling experiments to examine differences across six countries in the attitudes of consumers towards social and ethical issues that included both product related issues (such as recycled packaging) and general social factors (such as human rights). The experiments were conducted using over 600 respondents from Germany, Spain, Turkey, USA, India, and Korea. The results show that there is indeed some variation in the attitudes towards social and ethical issues across these six countries. However, what is more (...) telling are the similarities seen and the extent to which individual variation dominates observable demographics and country-based variables. (shrink)

Anthropocentrism was born with Man, and certain primitive tribes or ethnic groups considered themselves the center of the world. Their members assumed the generic name “the Men,” and all the rest, including other, tribes or ethnic groups, were part of a more or less hostile environment (to use the modern term).

The aim of this work is to study complex ecological models exhibiting simple dynamics. We consider large scale systems which can be decomposed into weakly coupled subsystems. Perturbation Theory is used in order to get a reduced set of differential equations governing slow time varying global variables. As examples, we study the influence of the individual behaviour of animals in competition and predator-prey models. The animals are assumed to do many activities all day long such as searching for food of (...) different types. The degree of competition as well as the predation pressure are dependent upon these activities. Preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study the effect of a change in the average individual behaviour of the animals on interspecific relationships. Computer simulations of the whole sets of equations are compared to simulations of the reduced sets of equations. (shrink)

The aim of this work is to present aggregation methods of hierarchically organized systems allowing one to replace the initial micro-system by a macro-system described by a few global variables. We also study the relations between the fast micro-dynamics and the slow macro-dynamics which can produce global properties. Emergence corresponds to a bottom-up coupling that is the result effected by a micro-level at a macro-level. As an example, we present prey-predator models with different time scales in an heterogeneous environment. A (...) fast time scale is associated to the migration process on spatial patches and a slow time scale is associated to growth and interactions between the populations. Preys must go on spatial patches where resources are located and where predators can attack them. The efficiency of the predators to catch preys is patch dependent. Perturbation methods allow us to aggregate the initial system of differential equations for the patch sub-populations into a macro-system of two differential equations governing the total population densities. We study the case of density independent and density dependent migrations. In the latter case, we show that different functional responses can emerge in the macro prey-predator model as a result of the coupling between the slow and fast systems. (shrink)

Aggregation methods allow one to replace a large scale dynamical system (micro-system) by a reduced dynamical system (macro-system) governing a small number of global variables. This aggregation of variables can be performed when two time scales exist, a fast time scale and a slow time scale. Perturbation theory allows to obtain an approximated aggregated dynamical system which describes the behaviour of a few number of slow time varying variables which are constants of motion of the fast part of the micro-system. (...) Aggregation methods are applied to the case of the devastation of the great barrier reef by the starfishes. We recall the Antonelli/Kazarinoff model which implies a stable limit cycle for the corals and starfish populations. This prey-predator model describes the interactions between two species of corals and the starfish. Then, we generalize the Antonelli/Kazarinoff model to the case of two spatial patches with a fast part describing the starfish migration on the patches and the human manipulation of the communities by divers and, a slow part describing the growth and the interactions between the populations. We obtain an aggregated model governing the total coral densities on the patches and the total starfish population. This model can exhibit stable limit cycle oscillations and a Hopf bifurcation. The critical value of the bifurcation parameter is expressed in terms of the proportions of coral species and starfish on the two patches. This implies for example that rather than random killing of starfish by the Australian military, it may be better to send teams of divers to outbreaking reefs when they first occur who will then manipulate the community structure to increase protection.

We study the case of two sibling species ofHippolais(Aves). Very little differences can be observed in the morphology of both species. The breeding area of these species are complementary. Roughly, one species breeds North and East of Europe (Hippolais icterina) while the other breeds South and West of Europe (Hippolais polyglotta). There exitst a narrow zone of sympatry passing through Burgundy. Since several years, it has been observed that this area of sympatry was moving in the North-East direction at a (...) European scale. This means that progressivelyH. icterina is declining and is replaced byH. polyglotta. Some assumptions can be made in order to explain this evolution, for instance competition or predation. Series of observations concerning the diets of nestlings of both species have been realized. These observations show some differences in the diet compositions. The breeding success of the two species has been studied. Numerical simulations of a competition model taking into account the observed differences between the food types eaten by the two species are presented. These simulations do not explain the regression ofH. icterina. Then, we present numerical simulations of a predation model with one predator attacking the nestlings of both species. These simulations show that with time one of the two preys must extinct. Predation rather than competition seems to be the right explanation. (shrink)

We present a mathematical model of two competing marine species that are harvested. We consider three models according to different levels of complexity, without and with species refuge and density-independent and density-dependent species movement between fishing area and refuge. We particularly study the effects of the fishing pressure on the outcome of the competition. We focus on conditions that allow an inferior competitor to invade as a result of fishing pressure. The model is discussed in relationship to the case of (...) the thiof and the octopus along the Atlantic West African coast. At the origin, the thiof was abundant and the octopus scarce in that region. Since, the fishing pressure has strongly increased in some fishing areas leading to the depletion of the thiof and the invasion of its competitor, the octopus. (shrink)

We present a dynamical model of a multi-site fishery. The fish stock is located on a discrete set of fish habitats where it is catched by the fishing fleet. We assume that fishes remain on fishing habitats while the fishing vessels can move at a fast time scale to visit the different fishing sites. We use the existence of two time scales to reduce the dimension of the model : we build an aggregated model considering the habitat fish densities and (...) the total fishing effort. We explore a regulation procedure, which imposes an average residence time in patches. Several equilibria exist, a Fishery Free Equilibria as well as a Sustainable Fishery Equilibria . We show that the dynamics depends on a threshold which is similar to a basic reproduction ratio for the fishery. When the basic reproduction ratio is less or equal to 1, one of the FFEs is globally asymptotically stable , otherwise one of the SFEs is GAS. (shrink)

We study the influence of the individual behaviour of animals on predator-prey models. Populations of preys and predators are divided into sub-populations corresponding to different activity classes. The animals are assumed to do many activities all day long such as searching for food of different types. The preys are more vulnerable when doing some activities during which they are very exposed to predators attacks rather than for others during which they are hidden. We study activity sequences of the animals and (...) also the effect of a change in the average individual behaviour of the animals on Lotka-Volterra prey-predator interactions. Numerical simulations are realized for the whole sets of equations (governing the subpopulations) and are compared to the simulations of the reduced sets of equation (governing the populations). We look for the validity of the method with respect to a scaling factor which measures the differences between the two time scales associated to the fast-varying variables and to the slow-time varying global variables. It is shown that when the two time scales differ of about two orders of magnitude, the approximation is satisfying. (shrink)

SUMMARYThe sixteenth-century Huguenot émigré Jacques Bellot played a seminal role in the history of English and French language tuition, and is remembered for composing some of the first descriptive grammars for learners of both languages. His methods remained in use throughout the seventeenth century after being incorporated into the often-reprinted Grammaire angloise. This essay considers a previously undiscussed manuscript copy of Bellot's Rules containing the Perfect Understanding of the French Tongue for evidence of his early attempts to teach French to (...) members of Sir Thomas Wroth's family. The Rules provides new insights into how Bellot and his printers adapted the content and parallel-text layout in his subsequent printed manuals to create more efficient aids to language learning.

S’interroger sur la présence des figures de proue zoomorphes dans l’image chrétienne, c’est poser les questions du discours symbolique mis en place, de la typologie de ses signes et de l’intentionnalité signifiante de l’auteur. Aussi cet article propose-t-il dans un premier temps de dévoiler, par le biais d’un examen terminologique, le processus cognitif déterminant les notions culturelles de « figure » et de « navire », avant d’analyser, dans un second temps, l’iconicité qui leur est rattachée. Est ainsi démontré que, (...) sur la base d’une dialectique latine et du remploi de formes antiques, la figure de proue participe d’une rhétorique fondamentale de la spiritualité chrétienne : la multiplication et démonstration du mystère de l’Incarnation. The paper aims to explore the meaning of zoomorphic figureheads in Christian medieval imagery. To do so, I question the symbolic discourse, the typology of pictural signs found in the picture and the signifying intentionality of the author. In a first part, I review the terminology used to name these figureheads; this, in a attempt to unveil the cognitive process behind the cultural notions of “figure” and “ship”: how do medieval people perceived and describe the element? In a second part, I analyse their iconocity: how are these zoomorphic figures pictured? And what does it reveal? It is thus demonstrated that, from a latin dialectic and a reference to ancient forms, the figurehead draws a rhetoric of a fundamental Christian spirituality, which multiplies the mystery of the Incarnation.

Our results show that some consumers are willing to pay for more socially acceptable products, but that most of those consumers do not think about the social product features of the products they purchase. Furthermore, our analyses demonstrate that consumers can be segmented based on their preferences for social product features and that these segments are not country-specific.

_ Source: _Volume 30, Issue 2, pp 236 - 253 There are four books that have been advertised in sales catalogues as possessing the inscription ‘Tho. Hobbes’ and having once been owned by Thomas Hobbes. But how confident can we be that they belonged to the famous philosopher? This research note gathers evidence for assessing whether or not this quartet of books were once in the possession of Hobbes of Malmesbury, with particular attention given to a previously undiscussed edition of (...) Josuah Sylvester’s _Devine Weekes and Workes_ sold to the University of Illinois in 1951 as Hobbes’s copy. The evidence is insufficient to connect any of the four books to Hobbes securely, and in at least one case an Oxford undergraduate of the same name emerges as a stronger candidate. This conclusion confirms that the catalogues at Chatsworth are our principal source for knowing which books Hobbes might have read. (shrink)
