The mathematics teacher's profession: the perspective of future

We present partial results of the design and implementation of a study program for the Mathematics Teacher Training. The research is developed in the light of the Anthropological Theory of the Didactic. This paper we analyze what gestures of the research and world questioning pedagogy are identified in a group of future teachers that study an essential issue to the mathematics teacher profession: how to teach mathematical knowledge? The work was carried out with futures mathematics teachers of the third year of a careen university in Argentina. The main results indicate that the future teachers, at the beginning of the study program, do not seem to carry out the distinctive didactics gestures of the research and questioning the world pedagogy.
Uncertainty estimation and figures of merit for multivariate calibration (IUPAC Technical Report)

Abstract This paper gives an introduction to multivariate calibration from a chemometrics perspective and reviews the various proposals to generalize the well-established univariate methodology to the multivariate domain. Univariate calibration leads to relatively simple models with a sound statistical underpinning. The associated uncertainty estimation and figures of merit are thoroughly covered in several official documents. However, univariate model predictions for unknown samples are only reliable if the signal is sufficiently selective for the analyte of interest. By contrast, multivariate calibration methods may produce valid predictions also from highly unselective data. A case in point is quantification from near-infrared (NIR) spectra. With the ever-increasing sophistication of analytical instruments inevitably comes a suite of multivariate calibration methods, each with its own underlying assumptions and statistical properties. As a result, uncertainty estimation and figures of merit for multivariate calibration methods has become a subject of active research, especially in the field of chemometrics.

Abstract--The wake flow behind a normal or an inclined plate is predicted by a discrete-vortex method. The vortex shedding phenomenon at the leading and the trailing edges is simulated by a vorticity creation technique according to the Kutta condition. This approach required that the strengths and locations of discrete vortices just shed from the edges be determined such that their presence in the flow field will offset the potential flow singularities at the edges of the plate. For gross features in the flow, the current model closely reproduced the measured values of previous experiments. As to the microscopic features in the wake flow, the predictions by the current model compare favorably with the experiments and with the previous solutions also by discrete-vortex simulation. For similar or better solutions, this approach requires about half of the computing time reported by other discrete-vortex approaches.
Mobile Intervention for Individuals With Psychosis, Dual Disorders, and Their Common Comorbidities: A Literature Review

Over 50% of people diagnosed with a severe mental illness, such as schizophrenia or bipolar disorder, will meet criteria for a substance use disorder in their lifetime. This dual disorder often starts during youth and leads to significant societal costs, including lower employability rates, more hospitalizations, and higher risk of homelessness and of suicide attempts when compared to those with a serious mental illness without substance misuse. Moreover, many individuals presenting with comorbid disorders also present with other psychological difficulties as well, such as personality disorders or anxiety and depression, also known as complex comorbid disorders. Transdiagnostic treatments that focus on core difficulties found in people with complex dual disorders, such as emotional regulation, are direly needed. Emotional regulation skills can help reduce distress related to psychotic symptoms and maintain abstinence in substance use disorders. New technologies in the field of communications have developed considerably over the past decade and have the potential to improve access to such treatments, a major problem in many health care settings. As such, this paper aims at: presenting core difficulties present in many individuals with dual disorders, reviewing the scientific literature pertaining to the use of mobile applications in mental health and addictions, and presenting the development and potential of a new application for emotional regulation for people with dual disorders.
Variable Carbon Source Utilization, Stress Resistance, and Virulence Profiles Among Listeria monocytogenes Strains Responsible for Listeriosis Outbreaks in Switzerland

A combination of phenotype microarrays, targeted stress resistance and virulence assays and comparative genome analysis was used to compare a set of Listeria monocytogenes strains including those involved in previous Swiss foodborne listeriosis outbreaks. Despite being highly syntenic in gene content these strains showed significant phenotypic variation in utilization of different carbon (C)-sources as well as in resistance of osmotic and pH stress conditions that are relevant to host and food associated environments. An outbreak strain from the 2005 Swiss Tomme cheese listeriosis outbreak (Lm3163) showed the highest versatility in C-sources utilized whereas the strain responsible for the 1983 to 1987 Vacherin Montd’or cheese listeriosis outbreak (LL195) showed the highest tolerance to both osmotic and pH stress conditions among the examined strains. Inclusion of L-norvaline led to enhanced resistance of acidic stress in all the examined strains and there were strain–strain-specific differences observed in the ability of other amino acids and urea to enhance acid stress resistance in L. monocytogenes. A strain dependent inhibition pattern was also observed upon inclusion of β-phenylethylamine under alkaline stress conditions. In targeted phenotypic analysis the strain-specific differences in salt stress tolerance uncovered in phenotypic microarrays were corroborated and variations in host cell invasion and virulence among the examined strains were also revealed. Outbreak associated strains representing lineage I serotype 4b showed superior pathogenicity in a zebrafish infection model whilst Lm3163 a lineage II serotype 1/2a outbreak strain demonstrated the highest cellular invasion capacity amongst the tested strains. A genome wide sequence comparison of the strains only revealed few genetic differences between the strains suggesting that variations in gene regulation and expression are largely responsible for the phenotypic differences revealed among the examined strains. Our results have generated data that provides a potential basis for the future design of improved Listeria specific media to enhance routine detection and isolation of this pathogen as well as provide knowledge for developing novel methods for its control in food.
La hormona de crecimiento promueve la expresión del gen zif268 en el hipocampo

Growth hormone (GH) plays an important role in cognitive processes such as memory consolidation, and it has been suggested that could be involved in processes of brain plasticity. These changes may occur by promoting gene expression in the brain. In this study we showed that GH administration (5ng/kg) for 7 days improves spatial learning and promotes expression of zif268 gene in the rat hippocampus. In addition, a Morris Water Maze (MWM) learning test induced a strong expression of zif268 gene in the hippocampus of adult rats. The effect was even greater when a MWM test and GH were applied together. Our results suggest that GH might be favoring plasticity processes in the hippocampus, by promoting gene expression.

Simulation in the Loop of Electric Vehicles

The objective of this chapter is to underline the importance of pre‐production and prototyping simulation in the loop of electric vehicles, by considering as many vehicle characteristics as possible. Basic simulations were made, using IPG CarMaker, to simulate electric vehicles with different properties for batteries, transmission, electric motors, aerodynamics of the vehicle, and most importantly, driver properties. This chapter also explains all the necessary steps to create a model and run it in IPG CarMaker, including data exports, so that the results could be reproduced easily. This chapter underlines the importance of batteries and answers the questions: what is the correct number of batteries that a vehicle must equip in order to have a bigger range? Basically, one should carry more batteries that add weight but at what range in price.
DIAGNOSTIC OF A QSPR MODEL: AQUEOUS SOLUBILITY OF DRUG-LIKE COMPOUNDS

A diagnostic test for a qSPR (quantitative Structure-Property Relationship) model was carried out using a series of statistical indicators for correctly classifying compounds into actives and non-actives. A previously reported qSPR model, able to characterize the aqueous solubility of drug-like compounds, was used in this study. Eleven statistical indicators like those used in medical diagnostic tests were defined and applied on training, test and overall data sets. The associated 95% confidence interval under the binomial distribution assumption was also computed for each defined indicator in order to allow a correct interpretation. Similar results were obtained in the training and test sets with some exceptions. The prior probabilities of active and non- active compounds proved not to be significantly different in the training and test sets. However, the probability of classification as active compounds proved to be significantly smaller in the training set as compared to the test set (p = 0.0042). The total fraction of correctly classified compounds proved to be identical in the training and test sets as well as in the overall set. Nevertheless, the overall model and the model obtained in the test set show a higher ability to correctly assign the non-active compounds to the non-active class while the model obtained in the training set has a higher ability to correctly assign the active compounds to the active class.
Publication explosion and ethics: A cause of concern

If there is a currency in the “business” of academic research and scholarship, it is ought to be “publications. ” The value of each publication, just like a currency note or coin, is different and varies on a number of factors. Academic publications generally describe articles which distribute research and scholarship most often done as a journal article, book, or thesis. The part that is not formally published but merely printed and distributed or posted on the internet is referred to as “gray literature. ” Most scientific and scholarly journals and books are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, discipline to discipline, and even time to time. As with the conduct of any research study, there are moral principles that set the standard for publications of the results of a given study. These moral principles or values, when applied to publication process and review, are called publication ethics.
Determination of Nucleopolyhedrovirus’ Taxonomic Position

To date, over 78 genomes of nucleopolyhedroviruses (NPVs) have been sequenced and deposited in NCBI. How to define a new virus from the infected larvae in the field is usually the first question. Two NPV strains, which were isolated from casuarina moth (L. xylina) and golden birdwing larvae (Troides aeacus), respectively, displayed the same question. Due to the identity of polyhedrin (polh) sequences of these two isolates to that of Lymantria dispar MNPV and Bombyx mori NPV, they are named LdMNPV-like virus and TraeNPV, provisionally. To further clarify the relationships of LdMNPV-like virus and TraeNPV to closely related NPVs, Kimura 2-parameter (K-2-P) analysis was performed. Apparently, the results of K-2-P analysis that showed LdMNPV-like virus is an LdMNPV isolate, while TraeNPV had an ambiguous relationship to BmNPV. Otherwise, MaviNPV, which is a mini-AcMNPV, also exhibited a different story by K-2-P analysis. Since K-2-P analysis could not cover all species determination issues, therefore, TraeNPV needs to be sequenced for defining its taxonomic position. For this purpose, different genomic sequencing technologies and bioinformatic analysis approaches will be discussed. We anticipated that these applications will help to exam nucleotide information of unknown species and give an insight and facilitate to this issue.
Recruitment and retention in clinical and experimental bereavement research: Lessons learned from creating a research registry

Abstract A small body of research investigates recruitment and retention of bereaved people in experimental and intervention research. The present study compares the effectiveness of different recruitment strategies implemented by a grief laboratory at a large state university in order to optimize recruitment efforts. The most effective method is letters sent to bereaved community members identified through online newspaper obituaries. Despite a small overall response rate, the large population from which to sample provides continuous accrual every month. Other methods include electronic/print media, community institution referrals, word of mouth and community outreach. Best practices for recruitment and retention are recommended.
EVALUATION TECHNIQUE IN THE SPI-CALCULUS FOR CRYPTOGRAPHIC PROTOCOLS

Hasan M. Al-Refai halrefai@philadelphia.edu. jo Hasan_alrefai@yahoo.com Mobile Phone #: 00962-777357755 Abstract Bisimulation as a technique could be well invested for proving authenticity and secrecy properties of cryptographic protocols to gain the legality of protocol optimization. In this paper, we will do some changes in the spi-calculus after the original work of M.Abadi and A.Gordon. Then we will introduce evade bisimulation following Abadi and Gordon’s framed bisimulation proposal, in which a convenient proof technique is presented. It will impose minimality requirements on the environment and detect the limit beyond which the bisimilarity is kept valid and furthermore it will avoid quantification over contexts. Also, it will give a solution for input transitions for the case of finite processes. Based on the revised spi-calculus would be used to prove that evade bisimilarity, an equivalence relation, is decidable for main security properties: Authenticity and Secrecy.

Collaborative haptic environments, multimodal interaction and communication, hand over task, experiment. Object manipulation is an important activity in everyday life that can also be performed in virtual environments. In the study presented here the extent to which haptic force feedback improves performance when a person hands over a virtual object to another is investigated. Joint manipulation of objects in collaborative virtual environments (CVE) has not been as well studied as single user manipulation. Recently it has also become possible to add haptic force feedback in virtual environments in order to support perception of form, weight, surface friction, texture and softness or hardness of virtual objects. A number of studies have shown that adding haptic force feedback improves single users performance when manipulating virtual objects. The added value of haptic force feedback lies in peoplesábility to feel the object they manipulate, which makes interaction faster and more precise. One study showed that the effect of haptic force feedback shortened task completion times when the task was to put a peg in a hole simulating assembly work [4]. Hasser et al. [5] showed that the addition of force feedback to a computer mouse improved targeting performance and decreased targeting errors. It has also been shown that if people get haptic force feedback from the context their performance is improved [11]. Results from that study showed that if a person gets haptic feedback from a table when sliding an object between two targets, performance is better than if moving the object through space without haptic feedback from the context. In many cases people need to manipulate virtual objects jointly and would benefit from haptic force feedback when doing so. A few studies have investigated issues regarding joint manipulation of virtual objects in a haptic collaborative virtual environment [2; 6; 8; 9; 10]. In one study subjects were asked to play a collaborative game in virtual environments with one of the experimenters who was an " expert " player. The players could feel objects in the common environment. They were asked to move a ring on a wire in collaboration with each other such that contact between the wire and the ring was minimised or avoided. Results from this study showed that haptic communication enhanced perceived togetherness and improved task performance when pairs of people worked together [2]. In another study it was shown that subjects performed tasks significantly faster and more precisely when …

A Two- Step CBR Method Based on Sequential Data

Case-Based Reasoning (CBR) is widely used for problem solving in many fields, but there still exist limitations for the problems with dynamic characteristics. This work tries to introduce approaches in Sequence Pattern Mining (SPM) to extend the capability of CBR for solving problems described with sequential data. We propose a SPM algorithm named wGSP, which takes user’s different concerns on events into consideration by weight setting, to discover typical patterns in case base. Then the support information of cases to typical patterns is used to depict cases and facilitate efficient case retrieval. The contribution of this work lies in two aspects: firstly it is an improvement to traditional CBR method for coping with sequential data based cases with better interpretability and higher efficiency; secondly, it provides flexibility for parameters setting in SPM to satisfy the personalized preferences of users. Finally through a calculating instance, the advantages and effectiveness of the two-step CBR method based on sequential data is illustrated.

USE OF POPULATION VIABILITY ANALYSIS AND RESERVE SELECTION ALGORITHMS IN REGIONAL CONSERVATION PLANS

Current reserve selection algorithms have difficulty evaluating connectivity and other factors necessary to conserve wide-ranging species in developing landscapes. Conversely, population viability analyses may incorporate detailed demographic data, but often lack sufficient spatial detail or are limited to too few taxa to be relevant to regional conservation plans. We developed a regional conservation plan for mammalian carnivores in the Rocky Mountain region using both a reserve selection algorithm (SITES) and a spatially explicit population model (PATCH). The spatially explicit population model informed reserve selection and network design by producing data on the locations of population sources, the degree of threat to those areas from landscape change, the existence of thresholds to population viability as the size of the reserve network increased, and the effect of linkage areas on population persistence. A 15% regional decline in carrying capacity for large carnivores was predicted within 25 years i.
