Agendas de investigación en Educación Matemática en España: una aproximación desde "ISI-web of knowledge" y ERIH

Este trabajo tiene como objetivo empezar a caracterizar la investigacion en educacion matematica realizada en Espana y publicada en revistas que aparecen en los listados del "ISI-web of knowledge" y del "European Reference Index for the Humanities" (ERIH) del European Science Foundation en el periodo 2000-2008. Esta aproximacion inicial se ha completado con la revision de las revistas evaluadas por CONACYT-Mexico debido a la alta relacion entre los investigadores espanoles y dichas revistas. Los articulos identificados se han agrupado en cuatro ambitos: A) Analisis didactico y organizacion del contenido matematico, (B) El estudiante para profesor, el profesor y el formador de profesores: Aprendizaje y desarrollo profesional (C) Construccion del conocimiento y procesos matematicos, y (D) ensenanza: profesores, contexto e interaccion. La identificacion de diferentes agendas de investigacion desde esta revision pone de manifiesto la variedad de enfoques y aproximaciones teoricas usadas por los investigadores para intentar responder a la gran variedad de preguntas planteadas. Finalmente se senala la necesidad de ir completando el mapa de las investigaciones y determinar la "transferencia del conocimiento" al sistema educativo.
An FMRI study of self-regulatory control and conflict resolution in adolescents with bulimia nervosa.

OBJECTIVE The authors examined functional activity in the frontostriatal systems that mediate self-regulatory capacities and conflict resolution in adolescents with bulimia nervosa. METHOD Functional magnetic resonance imaging was used to compare blood-oxygen-level-dependent response in 18 female adolescents with bulimia nervosa and 18 healthy female age-matched subjects during performance on a Simon spatial incompatibility task. Bayesian analyses were used to compare the two groups on patterns of brain activation during correct responses to conflict stimuli and to explore the effects of antecedent stimulus context on group differences in self-regulation and conflict resolution. RESULTS Adolescents with and without bulimia nervosa performed similarly on the task. During correct responses in conflict trials, frontostriatal circuits-including the right inferolateral and dorsolateral prefrontal cortices and putamen-failed to activate to the same degree in adolescents with bulimia nervosa as in healthy comparison subjects. Instead, deactivation was seen in the left inferior frontal gyrus as well as a neural system encompassing the posterior cingulate cortex and superior frontal gyrus. Group differences in cortical and striatal regions were driven by the differential responses to stimuli preceded by conflict and nonconflict stimuli, respectively. CONCLUSIONS When engaging the self-regulatory control processes necessary to resolve conflict, adolescents with bulimia nervosa displayed abnormal patterns of activation in frontostriatal and default-mode systems. Their abnormal processing of the antecedent stimulus context conditioned their brain response to conflict differently from that of healthy comparison subjects, specifically in frontal regions. It is suspected that functional disturbances in frontal portions of frontostriatal systems may release feeding behaviors from regulatory control, thereby perpetuating the conflicting desires to consume fattening foods and avoid weight gain that characterize bulimia nervosa.
Comparative Genetic Mapping in Boechera stricta, a Close Relative of Arabidopsis1[C][W][OA]

The angiosperm family Brassicaceae contains both the research model Arabidopsis (Arabidopsis thaliana) and the agricultural genus Brassica. Comparative genomics in the Brassicaceae has largely focused on direct comparisons between Arabidopsis and the species of interest. However, the reduced genome size and chromosome number (n = 5) of Arabidopsis complicates comparisons. Arabidopsis shows extensive genome and chromosome reshuffling compared to its close relatives Arabidopsis lyrata and Capsella rubella, both with n = 8. To facilitate comparative genomics across the Brassicaceae we recently outlined a system of 24 conserved chromosomal blocks based on their positions in an ancestral karyotype of n = 8, rather than by their position in Arabidopsis. In this report we use this system as a tool to understand genome structure and evolution in Boechera stricta (n = 7). B. stricta is a diploid, sexual, and highly self-fertilizing species occurring in mostly montane regions of western North America. We have created an F2 genetic map of B. stricta based on 192 individuals scored at 196 microsatellite and candidate gene loci. Single-nucleotide polymorphism genotyping of 94 of the loci was done simultaneously using an Illumina bead array. The total map length is 725.8 cM, with an average marker spacing of 3.9 cM. There are no gaps greater than 19.3 cM. The chromosomal reduction from n = 8 to n = 7 and other genomic changes in B. stricta likely involved a pericentric inversion, a chromosomal fusion, and two reciprocal translocations that are easily visualized using the genomic blocks. Our genetic map will facilitate the analysis of ecologically relevant quantitative variation in Boechera.
Tetrameric Ring Formation of Epstein-Barr Virus Polymerase Processivity Factor Is Crucial for Viral Replication

ABSTRACT The Epstein-Barr virus BMRF1 DNA polymerase processivity factor, which is essential for viral genome replication, exists mainly as a C-shaped head-to-head homodimer but partly forms a ring-shaped tetramer through tail-to-tail association. Based on its molecular structure, several BMRF1 mutant viruses were constructed to examine their influence on viral replication. The R256E virus, which has a severely impaired capacity for DNA binding and polymerase processivity, failed to form replication compartments, resulting in interference of viral replication, while the C95E mutation, which impairs head-to-head contact in vitro, unexpectedly hardly affected the viral replication. Also, surprisingly, replication of the C206E virus, which is expected to have impairment of tail-to-tail contact, was severely restricted, although the mutant protein possesses the same in vitro biochemical activities as the wild type. Since the tail-to-tail contact surface is smaller than that of the head-to-head contact area, its contribution to ring formation might be essential for viral replication.
Colonial Systems

Colonial systems are presented as an alternative to the mechanistic and organic systems paradigms. They are based upon the inclusion of an evolutionary social history (Ernst Mayr), species-level evolution (Eldredge and Gould), and local context (Martin Heidegger) as central premises in the definition of human systems. The colonial viewpoint of systems is differentiated from the mechanistic and organic models by ten different axioms that define how systems operate during both homeostasis (stability) and radical change. From the axiomatic descriptions of colonial systems, the method of punctuated prototyping is derived to clarify how local colonies survive and prosper by creating and adopting isolated prototypes. This change mechanism (1) requires the self-awareness to recognize the necessity for change, and (2) describes the empowerment necessary for the colonists to build and adopt successful prototypes. The colonial systems model can be applied to explanations about how information systems, organizations, and social institutions change. Further, colonies can be used as a metaphor to design new human systems that capture a greater degree of humanness than do the models of machines and organisms.
Improved numerical simulation and analisys of thermal response duing em exposure with FDTD-Lab

In this paper we suppose to discuss recent results of study influence of Electromagnetic (EM) exposure of mobile phones radiation on a human [1]. After calculations on different existed standard frequencies, with different distances between user's head and antenna using different antenna types were conducted (all calculation are part of ongoing MMFPII research project according to the specified) it appeared that there is more information needed for analyses of thermal response than just calculating peak values of Spatial Absorption Rate (SAR) and temperature rise to be studied. In [2] it was shown, that presence and position of the hand (which is actually required in order to use the phone) substantially can change users head exposure and radiation pattern. In this paper it is shown, that during analysis exposure we could consider another parameters of the antenna's position.
Support Vector Regression with Feature Selection for the Multivariate Calibration of Spectrofluorimetric Determination of Aromatic Amino Acids

Several artificial intelligent methods, including support vector regression (SVR), artificial neural networks (ANNs), and partial least square (PLS) are used for the multivariate calibration in the determination of the three aromatic amino acids (phenylalanine, tyrosine and tryptophan) in their mixtures by fluorescence spectroscopy. The results of the leave-one-out method show that SVR perform better than other methods, and appear to be good methods for this task. Furthermore, feature selection is performed for SVR to remove redundant features and a novel algorithm named PRIFER (prediction risk based feature selection for support vector regression) is proposed. Results on the above multivariate calibration data set show that PRIFER is a powerful tool for solving the multivariate calibration problems.
Perceived Risk and Benefit of Nuclear Waste Repositories: Four Opinion Clusters

Local public resistance can block the site‐selection process, construction, and operation of nuclear waste repositories. Social science has established that the perception of risks and benefits, trust in authorities, and opinion on nuclear energy play important roles in acceptance. In particular, risk and benefit evaluations seem critical for opinion formation. However, risks and benefits have rarely been studied independently and, most often, the focus has been on the two most salient groups of proponents and opponents. The aim of this exploratory study is to examine the often‐neglected majority of people holding ambivalent or indifferent opinions. We used cluster analysis to examine the sample (N = 500, mailed survey in German‐speaking Switzerland) in terms of patterns of risk and benefit perception. We reveal four significantly different and plausible clusters: one cluster with high‐benefit ratings in favor of a repository and one cluster with high‐risk ratings opposing it; a third cluster shows ambivalence, with high ratings on both risk and benefit scales and moderate opposition, whereas a fourth cluster seems indifferent, rating risks and benefits only moderately compared to the ambivalent cluster. We conclude that a closer look at the often neglected but considerable number of people with ambivalent or indifferent opinions is necessary. Although the extreme factions of the public will most probably not change their opinion, we do not yet know how the opinion of the ambivalent and indifferent clusters might develop over time.
Sepsis Upregulates CD14 Expression in a MyD88-Dependent and Trif-Independent Pathway

ABSTRACT An overwhelming immune response, particularly from macrophages, plays a critical role in survival and organ damage in sepsis patients. Toll-like receptors (TLRs) are important receptors to recognize the conserved motifs expressed by invading bacteria. The TLRs except TLR3 signal via a MyD88-dependent pathway. TLR3 uses a TRIF-dependent pathway, while TLR4 uses both MyD88 and TRIF-dependent pathways. Previous studies indicated that CD14 was necessary for TLRs-dependent production of pro-inflammatory cytokines. Blocking CD14 protected against the deleterious systemic inflammatory response associated with sepsis. The aim of this study was to determine the signaling pathway of TLR activation-induced CD14 expression in models of polymicrobial sepsis and in peritoneal macrophages. We found that CD14 expression was upregulated in the lung, liver, and kidney of septic mice induced by cecal ligation puncture. In cultured peritoneal macrophages, specific agonists for all TLRs, except for TLR3, increased CD14 expression. Lipopolysaccharide-induced upregulation of CD14 was abolished in peritoneal macrophages from MyD88 KO mice but increased in TRIF inhibitor, resveratrol pretreated wild-type macrophages. Moreover, MyD88 KO, but not TRIF KO mice, showed a decreased CD14 expression in the tissue of septic mice, which was associated with a strongly attenuated inflammatory response and increased survival rate. These data suggest that a MyD88-dependent and TRIF-independent pathway of TLR is activated in upregulating CD14 expression under septic conditions. This study deciphers a critical cross-talk between TLRs and CD14.
Biodiversity of Asterina species on Neotropical host plants: new species and records from Panama

Two new species of the genus Asterina are described from living leaves collected in provinces Chiriquí and Bocas del Toro in western Panama. Asterina alloplecti on Alloplectus ichtyoderma (Gesneriaceae) differs from other Asterina on Gesneriaceae by its stalked appressoria and host relationship. Asterina compsoneurae on Compsoneura sprucei (Myristicaceae) can be distinguished from other members of Asterina on Myristicaceae by its larger ascomata, larger, prominently spinose ascospores and host relationship. New records for Panama are Asterina corallopoda from a new host plant species (Solanum trizygum, Solanaceae), A. diplopoda, A. ekmanii from a new host plant species (Gonzalagunia rudis, Rubiaceae), A. siphocampyli from a new host plant genus and species (Burmeistera vulgaris, Campanulaceae) and A. styracina from a new host-plant species (Styrax argenteus, Styracaceae). This study increases the number of species of Asterina known for Panama from 12 to 19 and the number of Asterinaceae from 14 to 21. Asterina corallopoda, A. diplopoda, A. ekmanii, A. siphocampyli and A. styracina are illustrated for the first time. A phylogeny inferred from the analysis of LSU rDNA sequences of species of Asterina is presented. The diversity and host-plant patterns of known Neotropical species of Asterina are discussed.
Imaging Earthquake Source Complexity

Recent improvement in analysis methods, computational resources, and seismological and geological observations enable us to image earthquake sources in detail. This paper reviews various studies for each component of source imaging: model parameterization, data, theoretical wave calculations, and optimization. Differences in each of these aspects can lead to significant differences among models for the same event. The comparison between two recent large earthquakes demonstrates that the quality and quantity of a data set is critical in the source imaging problem. While the models of the 1999 Izmit, Turkey, earthquake show wide variation, those of the 1999 Chi-Chi, Taiwan, earthquake have common features. This is attributable to the fact that the data for the Izmit were sparse, while the data for the Chi-Chi earthquake were the most complete for any earthquake in history. Improved knowledge of source complexity and diversity of rupture behavior is leading to important new areas of study. As examples, we review current research problems concerning the frequency dependence of the earthquake source, imaging of dynamic rupture properties, and characterization of source complexity and scaling.

The Longitudinal Israeli Study of Twins (LIST)—An Integrative View of Social Development

The Longitudinal Israeli Study of Twins (LIST) is a social developmental study, which implements social-developmental, molecular genetic, epigenetic, and behavioral genetic methods to advance knowledge on the development of individual differences in social behavior. Twins are followed from the age of three and both observational and parental-questionnaire data are collected on their empathy, temperament, and pro-social behavior. The parenting styles of parents are also evaluated using self-reports and observations and DNA samples are collected from parents and twins. In the current paper, we provide a review of our recent work and discuss the future aims of the LIST.
La Elección del Método Contable en las Fusiones Empresariales: Análisis Empírico Desde una Perspectiva Contractual

RESUMEN En el ámbito español se dispone de amplia discrecionalidad en cuanto a la elección del método contable de las fusiones de empresas debido a la falta de regulación contable al respecto. Sin embargo, ésta es una de las áreas más problemáticas dadas las consecuencias económicas que se pueden derivar de la aplicación de uno u otro método. Tomando como base los planteamientos establecidos por la teoría positiva de la contabilidad, en este trabajo se analizan los factores que explican la contabilización de fusiones realizadas por una muestra de 406 empresas en un período de siete años, mediante la aplicación de modelos logit. Los resultados del estudio evidencian la influencia del tamaño y el endeudamiento de la sociedad absorbente, así como de la participación de la absorbente en la absorbida con anterioridad a la fusión en la elección del método contable.
Voicelikeness of musical instruments: A literature review of acoustical, psychological and expressiveness perspectives

What makes an artificial musical instrument such as the flute, trombone or cello sound like the human voice, and which of all instruments is the most voicelike? This article reviews acoustical and psychological arguments that might explain why a musical instrument would be likened to the singing human voice. The authors could find no evidence to support the idea of any single instrument being systematically, and consistently, regarded as voicelike. The human voice is frequently referred to as an ideal to which a well-played musical instrument should aspire. However, investigations are few that go beyond speculation and introspection regarding what instrument or instruments sound voicelike and why. Although no single instrument emerged as being systematically and consistently voicelike, a program of empirical research is suggested to determine whether there currently exist (possibly culturally promulgated) beliefs about what instrument is considered most voicelike and why.
The capacity region of frequency-selective Gaussian interference channels under strong interference

This paper presents the capacity region of frequency-selective Gaussian interference channels under the condition of strong interference, assuming an average power constraint per user. First, a frequency-selective Gaussian interference channel is modeled as a set of independent parallel memoryless Gaussian interference channels. Using non-frequency selective results, the capacity region of frequency-selective Gaussian interference channels under strong interference is expressed mathematically. Exploiting structures inherent in the problem, a dual problem is constructed for each independent memoryless channel, and solved. Furthermore, three suboptimal methods are compared with the capacity-achieving coding and power allocation scheme. Iterative waterfilling, a suboptimal scheme, provides close-to-optimum performance and has a distributed coding and power allocation scheme, which are attractive in practice.
Influence of Generation 2–5 of PAMAM Dendrimer on the Inhibition of Tat Peptide/ TAR RNA Binding in HIV‐1 Transcription

The special binding of Tat protein to TAR RNA leads to the transcription of HIV‐1 virus. In this study, the influence of 2–5 generation of PAMAM dendrimers on the inhibition of Tat protein/TAR RNA binding has been investigated. The absorption of PAMAM dendrimers on TAR RNA, fixed on a gold substrate through an avidin–biotion connection, was carried out by using a quartz crystal microbalance. Experimental result shows a Langmuir‐type isotherm could be used to describe this kind of binding, implying a specific and monolayer adsorption existed. The combination coefficient ()s can be calculated according to Langmuir Equation, having the order of G3 > G4 > G5 >Tat > G2, indicating that PAMAM G3, G4 and G5 having the possibility to be the inhibitors of HIV‐1 transcription. The migration time (Tmigra) of capillary electrophoretic technique has the same sequence as ()s. These two parameters could be used as simple and quantitative criteria for the selection of possible drugs from numerous candidates for HIV therapy in vitro.
