Wat werkt? Een verkenning van de praktische en wetenschappelijke kennis over informatievisualisaties.

Voordat een visualisatie tot stand komt, is daar een complex proces aan vooraf gegaan. Doel en doelgroepen worden vastgesteld (‘hoe bereiken we welk effect bij wie? ’) terwijl daarnaast de relatie tussen de data en de uiteindelijke visualisatie gedefinieerd moet worden (‘hoe laten we wat zien? ’). De productie en de receptie van een visualisatie zijn twee te onderscheiden processen. Bij het maakproces spelen vakkennis, design, technische mogelijkheden, brongegevens, doelgroep, mediakeuze en doelstelling een belangrijke rol. Bij receptie gaat het erom of en hoe de doelgroep de boodschap ontvangt: wordt die waargenomen en begrepen? En wat zijn de gevolgen bij de gebruiker? Hoewel receptie in de tijd volgt op het productieproces, spelen verwachtingen over receptie een belangrijke rol bij het maken van informatievisualisaties. De kennis over publieksreacties op visuele boodschappen is echter op verschillende manieren vastgelegd. Bij designers en anderen die betrokken zijn bij het maakproces van informatievisualisaties is er sprake van een verzameling van working theories (McQuail, 2010, pp. 13-14) die vooral op ervaring is gebaseerd. Bij empirisch onderzoek daarentegen worden responses op visuele cues daadwerkelijk gemeten. Zie Deel II van dit onderzoek. Doelstelling van dit onderzoek is deze twee vormen van kennis met elkaar te vergelijken. De vraag is welke veronderstellingen en verwachtingen er bij de beroepspraktijk bestaan en in hoeverre deze gestaafd, aangevuld of weersproken worden door empirisch, wetenschappelijk gefundeerd, onderzoek.
ROBOTIC JOINT ROTATIONAL DIRECTION CONTROL USING FUZZY LOGIC ASSESSMENT SYSTEM

One type of joints that are used usually in robotics are passive compliant joints. Although passive compliant joints ensure a smooth contact with the surroundings, but they cannot determine precisely the position of the members of the joint or the direction of the collision force due to lack of enjoyment of sensors that it brings about lack of robot’s awareness from its failure and finally collision occurs. The main task of this research is to investigate the application of a control algorithm for determining the direction of collision force or angular rotation direction in passive compliant joints when subjected to an external force. Therefore, here a control structure based on fuzzy inference system (FIS) is proposed for a passive compliant joint which is developed by conductive silicone sensors. The simulation results presented in this paper indicates that the proposed method can recognize angular rotation direction quickly and accurately.
VEGETATION AND SOIL EXPRESSION OF THE JAGUAR BASE METAL DEPOSIT, YILGARN CRATON

INTRODUCTION Most sulphide-rich base metal deposits in the tropics and sub-tropics have been found through the discovery of outcropping gossans or through recognition of the geochemical signature of gossan fragments in soil, lag and stream sediments. Many discoveries were made in the semi-arid and arid terrains of Australia, mostly in erosional terrains where gossans, or gossan remnants, are exposed at surface. With the exception of Ni sulphides, there have been few discoveries in areas of extensive, thick and complex regolith and low relief, such as in the Yilgarn Craton. We need to develop exploration techniques for finding base metal deposits in these difficult environments.
Analysis of Microbial Community That Dechlorinate 1,2-Dichloroethane to Ethene Which Was Enriched from River-sediment Contaminated with Chlorinated Compounds

The chemical compound, 1,2-dichloroethane (1,2-DCA) is one of the most abundant contaminants in the aquifer environments such as ground water and river sediment worldwide, which has toxic effects on nerv- ous system of human body. Biological reaction that reductively dechlorinates 1,2-DCA to nontoxic compound, ethene, has been receiving much attention as a bio-remediation process in the field of environmental technol- ogy. From concern of bioremediation of environments contaminated with 1,2-DCA, microorganisms were en- riched from a 1,2-DCA contaminated-river sediment in this study. The enrichment of 1,2-DCA dechlorinating microorganisms was carried out by the sequential transfer of microorganisms from the fresh sampled-river sediment by using a mineral medium amended with 1 mM 1,2-DCA, 80% hydrogen, 20% carbon dioxide, 5 mM acetate as energy or carbon sources. A sediment free-enrichment culture named as AR-DCA was obtained as the 6th transferred culture of the sediment, that dechlorinated completely 1 mM 1,2-DCA within one week. AR-DCA culture dechlorinated 1,2-DCA directly to ethene without any appearance of vinyl chloride as one chloride-dechlorinated product, suggesting the simultaneous elimination of two chloride from one 1,2-DCA which has been reported as dichloroelimination observed in the pure culture of Desulfitobacteium di- chloroeliminans strain DCA1. Microbial composition of AR-DCA culture was investigated by the identifica- tion of frequently-appearing operation taxonomic units (OTUs) in fragments of 16S rRNA amplified by PCR using a primer sets targeted to domain Bacteria. Four OTUs were obtained in 16S rRNA gene clone library and most frequent OTUs (47% of total OTUs) belonged to genus Dehalococcoides known as bacteria capable of dechlorination of various chlorinated aliphatics such as chloroethenes and chloroethanes.
Theoretical and numerical aspects in weak-compressible finite strain thermo-elasticity

In this essay, a constitutive model for nearly incompressible elastic behavior is extended to the case to thermal effects. First, the use is made of the multiplicative decomposition of the deformation gradient into a thermal and a mechanical part. The thermal part is purely volumetric. Additionally, the mechanical part is multiplicatively decomposed into a volume-preserving and a volume-changing part so that the final stress state shows the influences of the temperature-dependence. The proposed model is carefully studied in view of the thermo-mechanical coupling effects. Second, the model is implemented into a time-adaptive finite element formulation based on higher-order Rosenbrock-type methods, which is a completely iteration-free procedure so that really fast computations are available. The article concludes with a three-dimensional numerical simulation of a representative elastomeric tensile specimen.
Backward partial vertical integration with discriminatory pricing

We analyze the market impact of a partial vertical integration whereby a retail …rm acquires a non-controlling stake in the capital of an upstream …rm, which supplies an essential input. In addition, we assume that this upstream …rm can price discriminate between two groups of retail …rms: the retail …rm which (now) owns a stake in its capital and all of its retail rivals. Although apparently counterintuitive, we …nd that it is pro…t-maximizing for the upstream …rm to discriminate against its retail shareholder. Compared to a vertical separation scenario, this partial vertical integration induces input foreclosure, higher retail prices and lower social welfare. From a competition policy viewpoint, this suggests that such partial vertical integrations should be analyzed with particular concern.
Genetic Diversity among Nile Delta Isolates of Rhizoctonia solani Kühn Based on Pathogenicity, Compatibility, Isozyme Analysis and Total Protein Pattern

The present study obtained 12 isolates from Rhizoctonia solani Kühn isolated from Cotton L. , Trifolium L. and Vicia faba L. from different localities in the Nile Delta of Egypt. All strains were pathogenic and caused seed rot, wilt, stunting, and preemergence and post-emergence damping-off. The isolated strains produced different forms of infection cushions that ensure the pathogenicity of these strains. SDS-PAGE of the 12 R. solani isolates showed that although the R. solani isolates were isolated from very divergent host plants, the total soluble protein patterns among them were similar. Isozyme analysis revealed higher polymorphism among R. solani isolates using the EST isozyme. The cluster analysis based on isozyme data showed that the R. solani isolates fell into 4 distinct groups, whereas the dendrogram resulting from cluster analysis based on the compatibility test and other morphological characteristics of pathogen infection cushion showed that all R. solani isolates were placed into 3 main distinct groups.
Studying the Validity of the Efficient Market Hypothesis (EMH) in the Egyptian Exchange (EGX) after the 25th of January Revolution

There is no doubt that the close of the Egyptian Exchange (EGX) during the period 28/1- 22/3/2011 in the wake of 25th of January Revolution has a consequence on the efficiency of the stock market. This paper assesses the 'close-open-effect' on the main price indices. The results indicate the absence of unit roots in the main price indices before and after the revolution. This implies the rejection of weak-form efficiency. The estimation of the (EGARCH model) reflects information asymmetry after the revolution with bad news affecting the investors’ expectations more rapidly. In addition, a negative and significant 'close-open-effect' on the returns of the main price index is evident in the results.
Syllable position effects and gestural organization: Articulatory evidence from Russian

Previous articulatory studies have shown that English syllable-initial and syllable-final consonants exhibit different patterns of gestural organization. These differences – syllable position effects – are manifested primarily in the relative timing and magnitude of gestures. In general, syllable-initial consonants show more stable patterns of coordination and “tighter” articulatory constrictions than the same consonants in syllable-final position. This paper addresses the question of whether syllable position effects hold for other languages by examining the articulatory properties of some Russian syllable-initial and syllable final consonants: the palatal glide /j/ and labial stops /p/ and /p/. In general, the articulometer (EMMA) results confirm the hypothesis that the same consonants in these two positions differ with respect to their inter-gestural timing and gestural magnitude. At the same time, some predictions made based on patterns observed in English are not supported. The results thus provide evidence that, although syllable positions are characterized by different patterns of gestural organization, actual manifestations of this organization are not always the same; they may vary between gestures within a language and between similar gestures in different languages. It is further suggested that while the task-dynamics of gestural coordination is crucial to explaining syllable position effects, some non-contrastive and variable information still has to be specified – possibly by being lexically encoded.
Impact of Climate Variables on Revenue of Major Food Crops in Ghana : Ricardian Cross-Sectional Analysis (Communities and Livelihood Strategies in Developing Countries)

This study analyzes the impact of climate on net revenues of five major food crops in Ghana using 2005 national survey data. A multinomial logit regression is used to correct for crop selection bias in estimation of net revenue per hectare. Results of a multinomial logit regression show that farmers are likely to switch from the cultivation of maize, sorghum and rice to cassava and yam with marginal warming. Marginal increase in rainfall prompts farmers to switch from cassava and yam to the cultivation of maize, sorghum and rice. After incorporating selectivity bias, it was found that warming raises revenues from cassava, maize and sorghum but reduces that of rice and yam; additional rainfall reduces revenues of all crops except rice. With the exception of maize and sorghum, the choice of food crops to grow is motivated by higher net revenues per hectare obtainable from the cultivation of those crops. Marginal warming tends to increase expected net revenue in all ecological zones in Ghana but with much higher positive effect if farmers adapt to changing climate by switching crops. Marginal decrease in rainfall reduces expected net revenue in all ecological zones but reverses the losses into positive returns if farmers switch crops as a way of adapting to climate. This study suggests public investment in research on high yielding, heat and drought tolerant varieties of the above mentioned food crops in order to make crop switching a more beneficial exercise for farmers.
Horizontal evaluation method for the implementation of the construction products directive - emissions from construction products into indoor air

Worldwide different (mostly voluntary) approaches exist to evaluate emissions from construction products. The importance of the relation between construction products and health & environment is highlighted in the mandatory European Construction Products Directive (CPD). One of the objectives of the European Construction Products Directive (CPD) is to harmonize the technical specifications with regard to dangerous substances and construction materials as stated in the Essential Requirement N°3 “Hygiene, health and the environment” (ER3). The Belgian Building Research Institute (BBRI) is involved in the implementation of ER3 by participation in standardisation work on CEN (CEN/TC 351) and EOTA (EOTA PT9) level. This paper presents first results of ongoing BBRI research activities in collaboration with VITO (Flemish Institute for Technological Research) and ULg (Universite de Liege) concerning “horizontal evaluation method for implementation of the CPD (HEMICPD)”: http://www.bbri. be/go/hemicpd.
Canards Existence in FitzHugh-Nagumo and Hodgkin-Huxley Neuronal Models

In a previous paper we have proposed a new method for proving the existence of “canard solutions” for three- and four-dimensional singularly perturbed systems with only one fast variable which improves the methods used until now. The aim of this work is to extend this method to the case of four-dimensional singularly perturbed systems with two slow and two fast variables. This method enables stating a unique generic condition for the existence of “canard solutions” for such four-dimensional singularly perturbed systems which is based on the stability of folded singularities (pseudo singular points in this case) of the normalized slow dynamics deduced from a well-known property of linear algebra. This unique generic condition is identical to that provided in previous works. Application of this method to the famous coupled FitzHugh-Nagumo equations and to the Hodgkin-Huxley model enables showing the existence of “canard solutions” in such systems.
Arti ¢ cial intelligence-based decision support systemtomanage qualityofdurumwheat products

doi:10.1111/j.1757-837X.2009. 00029.x Abstract Background The long term competitiveness of food companies as well as the general health and wellness of citizens depend on the availability of products meeting the demands of safe, healthy and tasty foods. Therefore there is a need to merge heterogeneous data in order to develop the necessary decision support systems. Aims The objective of this paper is to propose an approach for durum wheat chain analysis based on a knowledge management system in order to help prediction. Material and Methods The approach is based on an information system allowing for experimental data and expert knowledge representation as well as reasoning mechanisms, including the decision tree learning method. Results The results include the structure of the knowledge management system for durum wheat process data, statistics and prediction results using decision trees. The use of expert rules for decision support is introduced and a method for confronting expert knowledge with experimental data is proposed. Different case studies from the durum wheat process are given. Discussion Our specific original contributions are: the design of a hybrid system combining both data and knowledge, the advantage of not requiring an a priori model, and therefore, an increased genericity, and the potential use for both risk and benefit analysis. Conclusion The approach can be reused for other purposes within the chain, and can also be transferred to other domains. Such a project is a starting point to integrate new knowledge from multidisciplinary fields, and constitutes a tool for structuring the international cereal research community.
General-relativistic resistive magnetohydrodynamics in three dimensions: Formulation and tests

We present a new numerical implementation of the general-relativistic resistive magnetohydrodynamics (MHD)equationswithintheWHISKYcode.ThenumericalmethodadoptedexploitsthepropertiesofimplicitexplicitRunge-Kuttanumericalschemestotreatthestifftermsthatappearintheequationsforlargeelectrical conductivities. Using tests in one, two, andthree dimensions, we show that ourimplementation is robustand recovers the ideal-MHD limit in regimes of very high conductivity. Moreover, the results illustrate that the code is capable of describing scenarios in a very wide range of conductivities. In addition to tests in flat spacetime, we report simulations of magnetized nonrotating relativistic stars, both in the Cowling approximationandindynamicalspacetimes.Finally,becauseofitsastrophysicalrelevanceandbecauseitprovidesa severe tested for general-relativistic codes with dynamical electromagnetic fields, we study the collapse of a nonrotating star to a black hole. We show that also in this case our results on the quasinormal mode frequencies of the excited electromagnetic fields in the Schwarzschild background agree with the perturbative studies within 0.7% and 5.6% for the real and the imaginary part of the ‘ ¼ 1 mode eigenfrequency, respectively. Finally we provide an estimate of the electromagnetic efficiency of this process.
Bioavailability in chicks of zinc from zinc propionate

SUMMARY The purpose of this experiment was to evaluate the relative bioavailability of Zn from Zn propionate relative to feed-grade Zn sulfate using BW gain and bone Zn as response criteria. For the first 7 d posthatching, chicks were fed a semipurified starter diet deficient in Zn (22 mg of Zn/kg). From d 8 to 21 birds were fed a control (20 mg of Zn/kg) semipurified diet containing ground corn, soy protein concentrate, and dextrose. The control diet was supplemented with 0, 6, or 12 mg of Zn/kg of diet from feed-grade Zn sulfate or organic Zn propionate. Using corn in the diet increased the level of phytate, an important Zn antagonist in nonruminant animals. As supplemental dietary Zn increased, a dose-dependent increase was observed in feed intake, weight gain, total Zn intake, tibia Zn concentration, and total tibia Zn. Zinc supplementation improved FE (feed:gain), but not in a dose-dependent manner. Relative bioavailability of Zn was determined using weight gain, tibia Zn concentration, and total tibia Zn, assuming a value of 100% for feed-grade Zn sulfate. Using relative slope assay, relative bioavailability of Zn propionate was 119, 116, and 116% compared with Zn sulfate, respectively. We concluded, based on these results, that bioavailability of Zn from organic Zn propionate is greater than feed-grade Zn sulfate in the presence of dietary phytate.
Microarray Analysis on the Differences of Gene Expression in Longissimus Dorsi Muscle Tissue Between 1 and 24 Months Chinese Red Steppes

Gene expression in different growth stages showed differences. In order to establish the correlation between gene expression mechanisms and beef traits formation which controlled by polygenes, microarray analysis was performed in Longissimus dorsi muscle tissue between 1 and 24 months Chinese red steppes. About 1,282 (5.6%) probes showed significant differences at the 2 growth stages and 126 genes showing strong correlation with beef traits formation were gained by the GO analysis. With the KEGG analysis, 63 pathways were found to be related to beef traits formation which involved 73 genes. About 28 genes were found in a single pathway while 35 genes were found in 2-16 pathways, respectively. The panel of transcripts and gene pathway analysis in different growth stages may be helpful for the study on beef traits formation and the gene expression profile construction in Longissimus dorsi muscle tissues would also make a model for screening candidate genes which have genetic effect on meat quality in bovine.
Conservation of breeds and maintenance of biodiversity : justification and methodology for the conservation of Animal Genetic Resources

Although the concept of genetic conservation has a long history it did not prevent the extinction of many breeds of domestic livestock. Significant intervention began to accelerate only in the mid-twentieth century through the work of both NGOs and governmental agencies. Endangered breeds now have been identified, catalogued and evaluated in most countries, and policies to maximise the maintenance of genetic diversity have been developed. The danger of irreversible breed substitution by dominant breeds is understood, and there is increasing awareness of the value of livestock with local adaptation.

Towards a "fingerprint" of paper network: separating forgeries from genuine by the properties of fibre structure

A novel method is introduced for distinguishing counterfeit banknotes from genuine samples. The method is based on analyzing differences in the networks of paper fibers. The main tool is a curvelet-based algorithm for measuring the distribution of overall fiber orientation and quantifying its anisotropy. The use of a couple or more appropriate parameters makes it possible to distinguish forgeries from genuine samples as concentrated point clouds in a two- or three-dimensional parameter space. Furthermore, the techniques of making watermarks is investigated by comparing genuine and counterfeit €50 banknotes. In addition, the so-called wire markings are shown to differ significantly from each other in all of investigated banknotes.
Does trade creation by social and business networks hold in services

Recent literature on the border effect has shown that the intensity of trade in goods is positively correlated with the migration stocks between any pair of countries/regions. The number of references for business networks is more limited, but they are also related with a reduction on information costs. In this article we investigate whether such a relation holds also for Spanish domestic trade flows in consumer services. To this end, we use a gravity model rooted in the Dixit--Stiglitz--Krugman theoretical framework and a unique data set on interregional trade flows for some of the main tourism service sectors, namely, accommodations and restaurants. Our industry-specific analysis finds a large positive effect for restaurants but a more limited effect for accommodations. Forces driving the demand in each sector explain this result and suggest the idea that although social networks can act as a substitute of firms in some sectors at the same time they can enhance trade flows in other sectors. We perform the same kind of analysis with a data set (obtained by a similar method) for domestic trade in goods and discover a different response to social and business networks. Finally, we treat the potential endogeneity by taking the instrumental-variable approach of the Poisson pseudo-maximum likelihood estimator and thus obtain consistent results.
