Invasive species: a costly catastrophe for native biodiversity

description: Species introduced from outside their natural range can be an economic boon, because they often seem to do better in their new home than in their place of origin. For example, various species of eucalyptus from Australia are widespread in Southeast Asia, China, India, California, and various parts of Africa, and South Africa's colourful proteas bless many of the world's gardens. Further, 'natural' is becoming an increasingly obsolete concept, as virtually all ecosystems have a strong and increasing anthropogenic component. People are designing the kinds of ecosystems they find congenial. The great increase in the introduction of aliens that people are importing primarily for aesthetic reasons - ornamentals to make their gardens more attractive - often leads to a net increase in species richness in their destination. It is quite likely, for example, that many parts of the world have far more species now than ever before, though this great increase of species numbers is usually at least partly at the expense of indigenous species (and thus reduces global species diversity). But a species introduced for noble economic or aesthetic objectives may escape into the wild, invading native ecosystems with disastrous results : they become alien invasive species (AIS). Greatly improved transport that enables traders to move goods around the world quickly is providing ideal opportunities for the accidental introduction of AIS, ranging from zebra mussels to disease-carrying mosquitoes to bacteria and viruses. It appears that few purposeful introductions have been accompanied by a careful consideration of the full costs involved. When the costs have become apparent, they can be astronomical; one study in the United States estimates that costs associated with alien species amount to some US$136 billion per year, and the recent disastrous fires in South Africa appear to be at least partly due to the spread of AIS. These costs usually must be paid by someone other than those who sponsored or promoted the introduction - often the general public. Decision-makers need to invest more in assessing the potential impacts before allowing introductions and to incorporate more biosecurity measures once the species has been introduced. Accidental introductions by definition are not exposed to a prior cost-benefit assessment, but assessments of the costs of such introductions can justify increased budgets to control and limit such accidental introductions. AIS issues also link to other issues of major policy concern, such as biotechnology, global trade, water, human health, and climate change. The Convention on Biological Diversity offers an important opportunity for addressing the complex global problems of introduced species through improved international cooperation.

description: Using the Frobenius method, we find high overtones of the Dirac quasinormal spectrum for the Schwarzschild black hole. At high overtones, the spacing for imaginary part of $ω_{n}$ is equidistant and equals to $\Im{ω_{n+1}}-\Im{ω_{n}} =i/8M$, ($M$ is the black hole mass), which is twice less than that for fields of integer spin. At high overtones, the real part of $ω_{n}$ goes to zero. This supports the suggestion that the expected correspondence between quasinormal modes and Barbero-Immirzi parameter in Loop Quantum Gravity is just a numerical coincidence.

description: A low background Micromegas detector has been operating on the CAST experiment at CERN for the search of solar axions during the first phase of the experiment (2002-2004). The detector operated efficiently and achieved a very low level of background rejection ($5\times 10^{-5}$ counts keV$^{-1}$cm$^{-2}$s$^{-1}$) thanks to its good spatial and energy resolution as well as the low radioactivity materials used in the construction of the detector. For the second phase of the experiment (2005-2007), the detector will be upgraded by adding a shielding and including focusing optics. These improvements should allow for a background rejection better than two orders of magnitude.

description: We report first principles analysis of electron-phonon coupling in molecular devices under external bias voltage and during current flow. Our theory and computational framework are based carrying out density functional theory within the Keldysh nonequilibrium Green's function formalism. We analyze which molecular vibrational modes are most relevant to charge transport under nonequilibrium conditions. For a molecular tunnel junction of a 1,4-benzenedithiolate molecule contacted by two leads, the low-lying modes of the vibration are found to be most important. As a function of bias voltage, the electron-phonon coupling strength can change drastically while the vibrational spectrum changes at a few percent level.

description: Controlling the interplay between localized spins and itinerant electrons at the oxide interfaces can lead to exotic magnetic states. Here we devise SrTiO3/LaTiO3/SrTiO3 heterostructures with varied thickness of the LaTiO3 layer (n monolayers) to investigate the magnetic interactions in the two-dimensional electron gas system. The heterostructures exhibit significant Kondo effect when the LaTiO3 layer is rather thin (n = 2, 10), manifesting the strong interaction between the itinerant electrons and the localized magnetic moments at the interfaces, while the Kondo effect is greatly inhibited when n = 20. Notably, distinct Shubnikov-de Haas oscillations are observed and a nonzero Berry phase of π is extracted when the LaTiO3 layer is rather thin (n = 2, 10), which is absent in the heterostructure with thicker LaTiO3 layer (n = 20). The observed phenomena are consistently interpreted as a result of sub-band splitting and symmetry breaking due to the interplay between the interfacial Rashba spin-orbit coupling and the magnetic orderings in the heterostructures. Our findings provide a route for exploring and manipulating nontrivial electronic band structures at complex oxide interfaces.

description: In this paper, the 2-category $\mathfrak{Rep}_{{\bf 2Mat}_{\mathbb{C}}}(\mathbb{G})$ of (weak) representations of an arbitrary (weak) 2-group $\mathbb{G}$ on (some version of) Kapranov and Voevodsky's 2-category of (complex) 2-vector spaces is studied. In particular, the set of equivalence classes of representations is computed in terms of the invariants $π_0(\mathbb{G})$, $π_1(\mathbb{G})$ and $[α]\in H^3(π_0(\mathbb{G}),π_1(\mathbb{G}))$ classifying $\mathbb{G}$. Also the categories of morphisms (up to equivalence) and the composition functors are determined explicitly. As a consequence, we obtain the the {\it monoidal} category of linear representations (more generally, the category of $[z]$-projective representations, for any given cohomology class $[z]\in H^2(π_0(\mathbb{G}),\mathbb{C}^*)) of the first homotopy group $π_0(\mathbb{G})$ as well as its category of representations on finite sets both live in $\mathfrak{Rep}_{{\bf 2Mat}_{\mathbb{C}}}(\mathbb{G})$, the first as the monoidal category of endomorphisms of the trivial representation (more generally, as the category of morphisms between suitable 1-dimensional representations) and the second as a subcategory of the homotopy category of $\mathfrak{Rep}_{{\bf 2Mat}_{\mathbb{C}}}(\mathbb{G})$.

The economics of biological invasions

Year: 2001
Subjects: Resource /Energy Economics and Policy

description: Biological invasions are an economic problem. Invasions are typically the intended or unintended consequence of economic activity. They impose real costs on society, and the risk of invasion depends on human behaviour. Effective control of invasions depends on using the right economic instruments and developing the right institutions. The problem has two special features. The first is that the risks of invasions may be very low, but the potential costs are high. Since they are not reflected in market prices, they are typically ignored. The second is that the control of potentially invasive species is a public good of the "weakest link" variety. Both features indicate a precautionary approach. To deal with the first, I recommend the use of environmental assurance bonds to cover society against the risks of invasive species whilst providing importers with an incentive to research the consequences of their actions. To deal with the second I recommend the development of an institution similar to the Atlanta Centre for Disease Control to provide the information and technical advice required if governments are to act, and a central organisation (involving UNEP, UNDP and the World Bank) to strengthen eradication, control of mitigation campaigns in those countries least able to deal with invasive species.

description: Effective management of invading alien plants in natural and semi-natural systems is imperative if we are to prevent enormous impacts. An integrated approach involving the combined use of a range of methods is usually necessary to control invasive alien plants effectively. The various methods that are available are usually classified as: mechanical methods (felling, removing of invading alien plants, often in conjunction with burning); chemical methods (using environmentally safe herbicides); and biological control (using species-specific insects and diseases from the alien plant's country of origin). Approaches available for integrated control depend on the species under consideration (features of individual species and the number and identity of species that occur together), features of the invaded systems, the availability of resources and other factors. Mechanical and chemical control are short-term activities, whereas rigorous and disciplined follow-up and rehabilitation are necessary in the medium term. Biological control can provide effective control in the short and medium term in some cases, and it is often the only really sustainable solution in the longer term. We suggest that the biological attributes of plants represent a stable set of attributes, which enable managers to devise control approaches, but that such approaches are likely to be upset by stochastic events such as fires, floods or budget cuts. While an approach of adaptive management, based on trial, error and continual improvement is a logical way in which to progress, the advent of powerful computer simulation modelling technologies will allow managers to do hundreds of 'trial and error' runs in order to explore the consequences of certain courses of action. This should represent an improvement on the current state of affairs, and should allow for better decision-making. We present a series of simulations to illustrate this point.

description: We utilize deep Chandra X-ray Observatory imaging and spectra of M82, the prototype of a starbursting galaxy with a multiphase wind, to map the hot plasma properties along the minor axis of the galaxy. We extract spectra from 11 regions up to 2.5 kpc from the starbursting midplane and model the data as a multi-temperature, optically thin thermal plasma with contributions from a non-thermal (power-law) component and from charge exchange (CX). We examine the gradients in best-fit parameters, including the intrinsic column density, plasma temperature, metal abundances, and number density of the hot gas as a function of distance from the M82 nucleus. We find that the temperatures and number densities of the warm-hot and hot plasma peak at the starbursting ridge and decreases along the minor axis. The temperature and density profiles are inconsistent with spherical adiabatic expansion of a super-heated wind and suggest mass loading and mixing of the hot phase with colder material. Non-thermal emission is detected in all of the regions considered, and CX comprises 8-25% of the total absorption-corrected, broad-band (0.5-7 keV) X-ray flux. We show that the abundances of O, Ne, Mg, and Fe are roughly constant across the regions considered, while Si and S peak within 500 pc of the central starburst. These findings support a direct connection between the M82 superwind and the warm-hot, metal-rich circumgalactic medium (CGM).

description: Invasive alien plants are invading some 125 million hectares in South Africa and Lesotho. More than R800 million has been invested in the clearing of invading alien plants in South Africa since October 1995. These clearing operations have had huge environmental, social and economic benefits but the benefits of the Working for Water Programme (WfW) have not yet been maximised. The initial treatment of a dense stand of invading alien plants could cost anything between R1,500 and R12,000 (on average R3,500) per hectare depending on the species and terrain factors involved. Investors have therefore had to ensure that maximum benefit is being derived from their investments. The environmental benefits of clearing operations include positive impacts on water resources, environmental stability and ecosystem function. The economic benefits include employment opportunities, value adding multipliers and economic empowerment of historically disadvantaged communities. By utilising biomass from clearing operations both the environmental and economic benefits of the programme are being enhanced. The environmental benefits include impacts on flood behaviour after clearing, dead biomass on fire intensity and its effects on soils and plant regeneration after fires, as well as the cost of fire management. The macro economic benefits of the secondary industry programme would include enhanced employment opportunities, increased government income through taxes, value-added multipliers, economic empowerment and training. Secondary industry projects in the Working for Water Programme have three primary objectives: 1. Maximising the positive economic impacts of the programme 2. Minimising dead plant biomass after clearing and 3. Minimising the net cost of clearing through the exploitation of biomass.

description: Increasing the implication of growing data generated by the Internet of Things (IoT) brings the focus toward extracting knowledge from the raw data derived from sensors. In the current cloud computing architecture, all the IoT raw data are transmitted to the cloud for processing, storage, and controlling things. Nevertheless, the scenario of sending all raw data to the cloud is inefficient as it wastes the bandwidth and increases the network load. This problem can be solved by providing IoT Gateway at the edge layer with the required intelligence to gain the knowledge from raw data to decide whether to actuate or offload complicated tasks to the cloud. This collaboration between the cloud and the edge is called distributed intelligence. This work highlights the distributed intelligence concept in IoT. It presents a deep investigation of distributed intelligence between the cloud and the edge layers under IoT architecture, with an emphasis on its vision, applications, and research challenges. This work aims to bring the attention of IoT specialists to distributed intelligence and its role to deduce current IoT challenges such as availability, mobility, energy efficiency, security, scalability, interoperability, and reliability.

description: It is now well recognised that invasive alien species, particularly tree species, often have much increased water usage compared with native vegetation. Perhaps less well understood are the reasons for this increased water use and whether such increases should be expected from all species of invading alien trees under all environmental conditions. This paper examines the reasons for increased water use from trees as compared with short crops. From a knowledge of these reasons and a knowledge of the limiting processes (the Limits Concept) governing alien tree and native tree and short crop water use, (derived from case studies in India and RSA), we suggest that it is now possible to assess under what conditions high water use by aliens may occur. Inverse solutions based on knowledge of growth rates are also suggested as another approach for assessing alien and native tree water use under water limited conditions. We conclude that in dry climates the greatest increase in water use from aliens, in both absolute and percentage terms, may occur in water limited rather than riparian (water unlimited) conditions. Hydrological models which can predict the spatially distributed increase in water use by aliens within catchments, coupled with ecological models which can predict controlled and uncontrolled invasion, can assist the evaluation and design of improved cost-effective eradication programmes. Such coupled models, linked with an economic evaluation component, should indicate in what circumstances the value of the extra streamflow released may alone be sufficient to cover the costs of the eradication programme and under what circumstances the ecological (protection of indigenous communities) and other socio-economic benefits also need to be taken into account to justify the costs of the programme.

description: Alors qu’il était en mission diplomatique en Flandres, Thomas More imagina sa « meilleure forme de communauté politique », qui par la suite, devait prendre la forme d’une œuvre fondatrice d’un genre nouveau : l’utopie littéraire. Il s’agissait alors pour Thomas More de répondre à son ami Érasme qui lui avait dédié l’Éloge de la Folie et demandé d’écrire à son tour un éloge de la sagesse. Ainsi, lors d’une de leurs rencontres, les deux humanistes se demandèrent dans quelle contrée du monde la raison pouvait se trouver. Nusquam ! répondirent-ils d’un commun accord. Nulle-part, ou nusquam, devint donc le territoire que More entreprit d’explorer afin de formuler la réponse à Érasme qu’il avait commencé à rédiger sous forme de notes dès 1510. Le projet de More était avant tout d’élaborer un discours. Cependant, ce discours allait devenir dans un premier temps la Nusquama, ou la Nulle Part, dont le contenu allait constituer l’essentiel du livre second d’Utopia publié pour la première fois en 1516 à Louvain.

description: We study the gravitational waves emitted by an inspiralling compact binary system in massive Brans-Dicke theory. In addition to the two tensor polarizations, which have been obtained in the previous work, we calculate explicitly and analytically the expressions for the time-domain waveforms of the two scalar polarizations. With the stationary phase approximations, we obtain the Fourier transforms of the two tensor polarizations. We find that when the scalar field is light, the waveforms can be mapped to the parametrized post-Einsteinian (ppE) framework and we identify the ppE parameters. However, when the scalar field is heavy, the ppE framework is not applicable. We also obtain the projected constraints on the parameters of this theory by gravitational wave observations of future ground-based detectors. Finally, we apply our result to the model proposed by Damour and Esposito-Farèse, $f(R)$ gravity, and screened modified gravity.

description: The dc Josephson critical current of a (S/M)IS tunnel structure in a parallel magnetic field has been investigated (here S is a superconductor, S/M is the proximity coupled S and paramagnet M bilayer and I is an insulating barrier). We consider the case when, due to the Hund's rule, in the M metal the effective molecular interaction aligns spins of the conducting electrons antiparallel to localized spins of magnetic ions. It is predicted that for tunnel structures under consideration there are the conditions when the destructive action of the internal and the applied magnetic fields on Cooper pairs is weakened and the increase of the applied magnetic field causes the field-induced enhancement of the tunnel critical current. The experimental realization of this interesting effect of the interplay between superconductivity and magnetism is also discussed.

Attitudes, interests and sport spectator profiling : variables affecting game attendance in a NHL franchise

description: ATTITUDES, INTERESTS AND SPORT SPECTATOR PROFILING: VARIABLES AFFECTING GAME ATTENDANCE IN A NHL FRANCHISE This study examined the literature on spectator profiling and evaluated current survey methodologies being used to profile hockey spectators and their preferences regarding NHL hockey game attendance. The research had two inter-related objectives. One was to investigate the consumer profiles of sport spectators associated with a specific NHL franchise, the Vancouver Canucks, and to relate these to game attendance. The second objective was to test and evaluate a questionnaire designed to incorporate latest thinking on variables that affect professional sports game attendance. Survey data were collected from 907 attendees at four Vancouver Canucks games and from 203 students at the University of British Columbia during the 2001-2002 NHL season. Two separate studies were conducted using the data. Study 1 investigated reasons for game attendance, and respondents' activity patterns and interests. Data analyses for study 1 included a confirmatory factor analysis for testing the validity of the game attendance items (reasons for game attendance), and a decision tree analysis for classifying spectators based on their reported game attendance frequencies, activity patterns, and interests. Results of study 1 indicate that the respondents' game attendance rates were affected by income, use of hockey websites, playing baseball when young, job, being accompanied by co-workers, ethnic background, perception of T.V. as the best promotional medium, personal fan history, and playing hockey when young. Study 2 investigated the relationship between spectators' opinions about sports and their game attendance, and attempted to identify potential predictors of game attendance levels. A confirmatory factor analysis was used in Study 2 to test the validity of the sport opinion items (opinions about sports), and a cluster analysis was used to identify unique spectator groups. Three distinctive spectator segments were identified, and the three groups varied on a number of dimensions including game attendance rates, sports participation history, and their opinions about the benefits of sports, community pride, cynicism about professional sports, attitude toward professional athletes, perceived time costs, role of government, and attitude toward amateur sports. The research found evidence of national cultural differences between Canadian sports spectators and their American counterparts. It is recommended that future research investigate national and regional cultural differences as well as differences between major and minor league sports and competitive factors in local sports markets.

A physical model based on the dressed field correlations of vacuum fluctuations is used, generalizing a model previously introduced for three ground-state atoms. Although the three-body potential with one excited atom is already known in the literature, our model gives new insights on the nature of non-additive Casimir-Polder forces with one or more excited atoms.

description: The existence of a minimum length in quantum gravity is investigated by computing the in-in expectation value of the proper distance in the Schwinger-Keldysh formalism. No minimum geometrical length is found for arbitrary gravitational theories to all orders in perturbation theory. Using non-perturbative techniques, we also show that neither the conformal sector of general relativity nor higher-derivative gravity features a minimum length. A minimum length scale, on the other hand, seems to always be present when one considers in-out amplitudes, from which one could extract the energy scale of scattering processes.

The role of initial state reconstruction in short and long time deviations from exponential decay

description: We consider the role of the reconstruction of the initial state in the deviation from exponential decay at short and long times. The long time decay can be attributed to a wave that was, in a classical-like, probabilistic sense, fully outside the initial state or the inner region at intermediate times, i.e., to a completely reconstructed state, whereas the decay during the exponential regime is due instead to a non-reconstructed wave. At short times quantum interference between regenerated and non-regenerated paths is responsible for the deviation from the exponential decay. We may thus conclude that state reconstruction is a ``consistent history'' for long time deviations but not for short ones.

description: The Working for Water Programme's willingness to take on the inter-sectoral, multi-disciplinary, and partnerships co-ordination role in its invasive alien plant clearing activities has moulded it into a leading example of possible ways to successfully run a public works programme. The social development objectives within the programme present some of the most profound challenges for this multi-focus initiative. Although essentially the programme addresses the problem of invasive alien vegetation, it has grown to take on the challenge of high unemployment levels and general socio-economic uplift in communities where it operates. This means that it has to address not just the training component of its workers, contractors and management, but also the workers' health, employment conditions, and general social well being. These additional challenges have resulted in the formation of partnerships with government departments responsible for these sectors (such as Health and Welfare, Agriculture, Land Affairs and others), and with other organisations at the local level. This paper discusses research findings from a study on the socio-economic impacts of the programme on the lives of workers. It also provides an analysis of the different views of the type of employment (short vs. long term) preferred by workers and contractors.

description: (Abridged) We investigate how the shapes and angular momenta of galaxy and group mass dark matter halos in a LCDM N-body simulation are correlated internally, and how they are aligned with respect to the location and properties of surrounding halos. We explore these relationships down to halos of much lower mass (10^11/h Msun) than previous studies. The halos are triaxial, with c/a ratios of 0.6+-0.1. More massive halos are more flattened. The principal axes are very well aligned within 0.6 r_vir. The angular momentum vectors are also reasonably well aligned except between the very outermost and very innermost regions of the halo. The angular momentum vectors tend to align with the minor axes, with a mean misalignment of ~25 degrees, and lie perpendicular to the major and intermediate axes. The properties of a halo at 0.4 r_vir are quite characteristic of the properties at most other radii within the halo. There is a very strong tendency for the minor axes of halos to lie perpendicular to large scale filaments. This alignment extends to much larger separations for group and cluster mass halos than for galaxy mass halos. As a consequence, the intrinsic alignments of galaxies are likely weaker than previous predictions, which were based on the shapes of cluster mass halos. The angular momenta of the highest concentration halos tend to point toward other halos. The angular momenta of galaxy mass halos point parallel to filaments, while those of group and cluster mass halos show a very strong tendency to point perpendicular to the filaments. This suggests that group and cluster mass halos acquire most of their angular momentum from major mergers along filaments, while the accretion history of mass and angular momentum onto galaxy mass halos has been smoother.

description: We demonstrate the potential of new adaptive optical technology to expand the detection horizon of gravitational-wave observatories. Achieving greater quantum-noise-limited sensitivity to spacetime strain hinges on achieving higher circulating laser power, in excess of 1~MW, in conjunction with highly-squeezed quantum states of light. The new technology will enable significantly higher levels of laser power and squeezing in gravitational-wave detectors, by providing high-precision, low-noise correction of limiting sources of thermal distortions directly to the core interferometer optics. In simulated projections for LIGO~A+, assuming an input laser power of 125~W and an effective injected squeezing level of 9~dB entering the interferometer, an initial concept of this technology can reduce the noise floor of the detectors by up to 20\% from 200~Hz to 5~kHz, corresponding to an increment of 4~Mpc in the sky-averaged detection range for binary neutron star mergers. This work lays the foundation for one of the key technology improvements essential to fully utilize the scientific potential of the existing 4-km LIGO facilities, to observe black hole merger events past a redshift of~5, and opens a realistic pathway towards a next-generation 40-km gravitational-wave observatory in the United States, Cosmic~Explorer.

description: Keck adaptive optics imaging with a physical resolution of 0.4 AU resolves the inner (15-80 AU) disk of AU Mic (GJ 803), the nearest known scattered light disk to Earth. The inner disk is asymmetric and possesses a sharp change in structure at 35 AU. The disk also shows spatially localized enhancements and deficits at 25-40 AU separations. The overall morphology points to the influence of unseen larger bodies and resembles structures expected from recent planet formation. AU Mic is coeval with the archetypical debris disk system beta Pic, and the similarities between their two disks point to synchronous disk evolution. Multiple indications of substructure appear to be common in circumstellar disks at an age of ~12 Myr.

title: L' île de la Première Solitude de Góngora : une poétique du renouveau
Creators: name: Dumora, Florence

description: Ce poème narratif de 1091 vers, qui engage le poète en tant que simple narrateur d'un récit presque autonome, adopte dans sa majeure partie le point de vue d'un personnage, dénommé « pèlerin », qui est pour ainsi dire réduit au rôle de regard. Sa situation dramatique combine les éléments suivants : un échec sentimental qui l'a poussé à entreprendre un voyage maritime (fuite) interrompu violemment par un naufrage lors d'une tempête ; cet accident le fait échouer sur une île, terre inconnue, qui associe salut, découverte et rencontre mais aussi souvenir (avec une double dimension spatio-temporelle : temps passé et espace ancien, abandonné). L'esprit du lecteur sera occupé par une question, entre autres : quel lien unit « solitude », titre et porte d'entrée du texte (pour reprendre l'idée de seuil chez Genette), et « île », le lieu de la fiction où nous fait arriver et entrer, conjointement avec le personnage, ce titre ? Nous verrons que l’histoire de la rencontre entre cet être pèlerin et autrui se comprend comme désir d’un certain type de relation à l’autre ; de cette manière l’île, en tant que configuration géographique spécifique, exprime une aspiration, un rêve de l’autre. Par ailleurs l’écriture n’exploite pas l’île seulement comme thème topographique (lieu de l’action), mais elle en prend la marque, avec une conception du traitement des mots qui tend à les isoler, dans la syntaxe, dans la lecture. La langue poétique, au-delà de l’esthétique, propose un autre système de communication, incite à envisager autrement les mots, leur rapport aux choses, et le monde. Le lecteur fournit un travail de réception complexe où le visuel et l’intellectuel concourent à l’établissement du sens, et plus justement, où l’effort intellectuel concourt à une vision graduelle, autant optique qu’intellective abstraite, qui lui fait suivre un authentique processus de découverte.

description: Dans l’un des célèbres portraits d’Élisabeth Ire que l’on peut voir à la National Gallery de Londres, le « Ditchley portrait », qui date de 1592, le corps même de la reine, tel qu’il apparaît dans le tableau, semble évoquer l’insularité de l’Angleterre et donne l’impression d’être une partie intégrante de la carte du pays dessinée sur le sol et dont la reine semble surgir ici comme un relief. Élisabeth est, en effet, une île dans ses représentations, dont celle de la reine vierge, territoire imprenable se confondant avec l’île forteresse que l’ennemi espagnol ne peut envahir, tout comme son beau-frère, Philippe II, veuf de Marie Tudor, n’avait pu la convaincre d’un mariage espagnol.

description: Molecular dynamics simulations are used to study the equilibrium distribution of monovalent ions in a nanopore connecting two water reservoirs separated by a membrane, both for the empty pore and that with a single stranded DNA molecule inside. In the presence of DNA, the counterions condense on the stretched macromolecule effectively neutralizing it, and nearly complete depletion of coions from the pore is observed. The implications of our results for experiments on DNA translocation through alpha-hemolysin nanopores are discussed.

Forests and Hydrological Services: Reconciling public and science perceptions

description: This paper compares and contrasts the science and public perceptions of the role of forests in relation to water quantity (annual and seasonal runoff and recharge) and erosion. It is suggested that the disparity between the two perceptions needs to be addressed before we are in a position to devise and develop financing mechanisms for the conservation and protection of indigenous forests. Examples are given of three ‘interactive’ forest hydrology research programmes: in the UK, South Africa and Panama. Through the involvement of stakeholder groups, often with representatives comprising both the science and public perceptions, interactive research programmes were designed not only to derive new research findings but also to achieve better ‘ownership’ and acceptance of research findings by the stakeholders. Following this approach, a new programme of research is outlined, aimed at improving our knowledge of forest impacts on seasonal flows and which represents DFID’s contribution to the UN Year of Mountains, 2002. It is concluded that to move towards a reconciliation of the different perceptions and to connect policy with science will require further research to understand how the ‘belief’ systems underlying the science and public perceptions have evolved, and better dissemination of research findings.

description: Physiotherapists rehabilitate with movement, intending to recover the function and quality of life of the patients. It is essential to know the musculoskeletal system. The muscular system is composed of several muscles with respective origins, insertions and function directly dependent on the kinetic chain, and muscular type. Muscles are affected by trigger points, one of the leading causes of myofascial pain, and disability. Trigger points also cause pseudo weakness that can and will be a negative impact on the rehabilitation program. In this paper, we show the importance of proper evaluation and why the physiotherapist should be closely alert to the pseudo weakness condition, never neglecting it, and aiming to improve the rehabilitation program.
