Preparing an L2 Role-play: How Students Manage L2 Deficits

There is considerable variation in the implementation of role-play activities in second language (L2)/foreign language (FL) classroom settings, and little information is available about how students actually manage them, particularly with regards to overcoming their L2 deficits. This study examines the preparation of role-plays by university students in an intermediate Spanish class. When confronted with challenging aspects of the L2, they employed a variety of strategies, such as asking classmates, consulting reference materials, and modifying their original ideas to manage the task. This analysis of students’ strategy use provides insights into how teachers might implement role-play activities more effectively into second and foreign language classes. Il existe de nombreuses variations dans la façon dont on incorpore les jeux de rôle dans les classes de langue seconde (L2)/langue étrangère (FL), et peu de renseignements par rapport aux stratégies adoptées par les étudiants eux-mêmes, surtout en ce qui concerne leurs déficits en L2. Cette étude examine la préparation des jeux de rôle par des étudiants de niveau universitaire dans un cours intermédiaire d’espagnol. Face aux aspects difficiles de la L2, ils ont employé une variété de stratégies pour compléter la tâche, telles l’interrogation d’autres étudiants, la consultation des matières de référence, et la modification de leur idée initiale. Cette analyse des stratégies adoptées par les étudiants propose aux professeurs des idées pour introduire de façon plus efficace les jeux de rôle dans les cours de langue seconde et étrangère.
Syndesmosis Fixation: A Comparison of Three and Four Cortices of Screw Fixation Without Hardware Removal

Background: Great variability exists in methods of stabilization for syndesmotic disruptions of the ankle. We hypothesized that syndesmotic screw fixation with 3.5-mm fully threaded cortical screws through either three or four cortices would have similar strength and rate of mechanical failure and that retention of screws after fracture healing would not result in adverse clinical symptoms. Methods: In a prospective, surgeon-randomized study at a Level-one trauma center, 127 patients with syndesmotic disruptions were treated surgically. Seven patients were lost to followup, leaving 120 for review. Syndesmotic disruptions were stabilized with 3.5-mm fully threaded cortical screws placed through three or four cortices. Screws were removed only if symptomatic. Outcome criteria were screw failure, loss of reduction, and need for hardware removal. Results: Fifty-nine patients received fixation through three cortices and 61 patients received fixation through four cortices. Mean follow-up was 150 days. In the group with stabilization through three cortices, hardware failure occurred in five patients (8%) and three had a loss of reduction. In the group with stabilization through four cortices, hardware failure occurred in four patients (7%); all were asymptomatic and did not require screw removal. There was no loss of reduction in that group. Comparing the two groups using binary logistic analysis, there was no difference in loss of reduction (p = 0.871), screw breakage (p = 0.689), or need for hardware removal (p = 0.731). Conclusion: The data suggest that either three or four cortices of fixation can be used when stabilizing syndesmotic injuries of the ankle. There was a trend towards higher loss of reduction in the group with tricortical fixation when weightbearing restrictions were not followed. Retention of the syndesmotic screws, even with mechanical failure, does not pose a clinical problem. Weightbearing can be allowed at 6 to 10 weeks without routine removal of screws.
Parallelisms between sea surface temperature changes in the western tropical Atlantic (Guiana Basin) and high latitude climate signals over the last 140 000 years

Abstract. Sea surface temperatures (SST) in the Guiana Basin over the last 140 ka were obtained by measuring the C37 alkenone unsaturation index Uk'37 in the sediment core MD03-2616 (7° N, 53° W). The resulting data set is unique in the western tropical Atlantic region for this period. The SSTs range from 25.1 to 28.9 °C, i.e. glacial–interglacial amplitude of 3.8 °C, which is in the range of change of other tropical areas. During the last two interglacial stages (marine isotope stages; MIS1 and MIS5e) and warm long interstadials (MIS5d-a), a rapid transmission of climate variability from Arctic–tropical latitudes is recorded. During these periods, the MD03-2616 SSTs show a conspicuous parallelism with temperature changes observed in Greenland and SST records of North Atlantic mid-latitude cores (Iberian Margin 38° N, Martrat et al., 2007). The last deglaciation in the Guiana Basin is particularly revealing. MIS2 stands out as the coldest period of the interval analysed. The events recorded in Guiana parallel northern latitude events such as the Bolling–Allerod warming and the Younger Dryas cooling which ensued. These oscillations were previously documented in the δ18O of the Sajama tropical ice core (Bolivia) and are present in Guiana, with rates of ca. 6 °C ka−1 and changes of over 2 °C. During the glacial interval, significant abrupt variability is observed, e.g. oscillations of 0.5–1.2 °C during MIS3, which is about 30 % of the maximum glacial–interglacial SST change. In the MD03-2616 record, it is possible to unambiguously identify either the Dansgaard–Oeschger oscillations described in northern latitudes or the SST drops associated with the Heinrich events characteristic of North Atlantic records. Although these events form the background of the climate variability observed, what truly shapes SSTs in the Guiana Basin is a long-term tropical response to precessional changes, which is modulated in the opposite way to Northern Hemisphere variability. This lack of synchrony is consistent with other tropical records in locations to the north or south of the Guiana Basin and evidences an Arctic–tropical decoupling when a substantial reduction in the Atlantic meridional overturning circulation (AMOC) takes place.
Discriminant Validity of Self-Reported Emotional Intelligence: A Multitrait-Multisource Study

A major stumbling block for emotional intelligence (EI) research has been the lack of adequate evidence for discriminant validity. In a sample of 280 dyads, self- and peer-reports of EI and Big Five personality traits were used to confirm an a priori four-factor model for the Wong and Law Emotional Intelligence Scale (WLEIS) and a five-factor model for Goldberg’s International Personality Item Pool (IPIP). After demonstrating measurement equivalence between self-report and peer-report for both scales, the authors show discriminant validity between the four EI subfacets and Big Five personality traits. This is accomplished through a series of structural equation models fit to the mutitrait-multimethod matrix. Despite their conclusion of discriminant validity, the authors note strong latent correlations between Others’ Emotion Appraisal and trait Agreeableness (φ = .87), between Use of Emotion and trait Conscientiousness (φ = .73), between Regulation of Emotion and trait Neuroticism (φ = −.66), and between Self Emotion Appraisal and trait Neuroticism (φ = −.66). There is also post hoc evidence of potential leniency in self-reported emotion regulation. Results point to the utility of peer-report methods as well as the relative construct validity of various subfacets of self-reported emotional competence.
Large-Scale Optimization for Evaluation Functions with Minimax Search

This paper presents a new method, Minimax Tree Optimization (MMTO), to learn a heuristic evaluation function of a practical alpha-beta search program. The evaluation function may be a linear or non-linear combination of weighted features, and the weights are the parameters to be optimized. To control the search results so that the move decisions agree with the game records of human experts, a well-modeled objective function to be minimized is designed. Moreover, a numerical iterative method is used to find local minima of the objective function, and more than forty million parameters are adjusted by using a small number of hyper parameters. This method was applied to shogi, a major variant of chess in which the evaluation function must handle a larger state space than in chess. Experimental results show that the large-scale optimization of the evaluation function improves the playing strength of shogi programs, and the new method performs significantly better than other methods. Implementation of the new method in our shogi program Bonanza made substantial contributions to the program's first-place finish in the 2013 World Computer Shogi Championship. Additionally, we present preliminary evidence of broader applicability of our method to other two-player games such as chess.
The Impact of Local Decision-Making in Regional Development Schemes on the Achievement of Efficiency in EU Funds

— European Union candidate status provides a strong motivation for decision-making in the candidate countries in shaping the regional development policy where there is an envisioned transfer of power from center to the periphery. The process of Europeanization anticipates the candidate countries configure their regional institutional templates in the context of the requirements of the European Union policies and introduces new instruments of incentive framework of enlargement to be employed in regional development schemes. It is observed that the contribution of the local actors to the decision making in the design of the allocation architectures enhances the efficiency of the funds and increases the positive effects of the projects funded under the regional development objectives. This study aims at exploring the performances of the three regional development grant schemes in Turkey, established and allocated under the pre-accession process with a special emphasis given to the roles of the national and local actors in decision-making for regional development. Efficiency analyses have been conducted using the DEA methodology which has proved to be a superior method in comparative efficiency and benchmarking measurements. The findings of this study as parallel to similar international studies, provides that the participation of the local actors to the decision-making in funding contributes both to the quality and the efficiency of the projects funded under the EU schemes.
Analysis and Design of APWM Half-Bridge Series Resonant Converter With Magnetizing Current Assisted ZVS

In an asymmetrical pulse-width-modulated half-bridge (APWM HB) series resonant converter, an auxiliary LC network is provided for ensuring zero-voltage switching (ZVS) over a wide range of line and load variations. However, it comes at the cost of increased number of components and reduced efficiency and reliability. This paper presents a novel design methodology for the standard APWM HB resonant topology, which uses the magnetizing current and eliminates the need for extra components. The converter with the proposed design methodology operates at the resonant frequency of the tank and features load-independent ZVS for a wide range of input voltage variation with minimal magnetizing current. Empirical formulae are derived to design the resonant network and the magnetizing inductance of the high-frequency transformer systematically in a flowchart-based manner. The proposed design is validated by using simulations as well as experiments and is compared with a reference APWM HB series resonant converter design that uses an auxiliary LC circuit for ZVS. Two separate experimental prototypes of the two converters rated for 30 W, 48 V/5 V with a switching frequency of 500 kHz were built and tested in the laboratory. It was found that the converter with the proposed design methodology, apart from having lower component count, is about 3% more efficient than the reference topology at the rated power.
Normalizing Discrete Circuit Features with Statistically Independent values for incorporation within a highly Secure Encryption System

Protecting hardware devices from unwanted software attacks is a current area of major security concern. Coupled with the need to secure and verify data sent to and from such devices, the need to supply systems capable of uniquely identifying and securing hardware devices is considerable and imminent. This paper introduces techniques which possess the potential to generate unique identifying codes for given hardware devices based on measurable quantities or features associated with the given hardware and software configurations executing upon it. The techniques are investigated by considering abstract properties in order to validate primarily the feature normalization techniques employed prior to the code generation phase which allows features with highly variable distributions, and whose component values are independent of each other, to be employed within the code generation system.
Epenthesis, Geminates, and the OCP in Finnish

This study re-evaluates the representation of phonological length in Finnish in the light of Optimality Theory. The Obligatory Contour Principle (OCP) prohibits sequences of identical elements. It follows that long segments cannot be represented as sequences of two short segments, but must be interpreted monosegmentally (i.e. non-linearly). In Finnish, long segments have been traditionally represented bisegmentally, consequently violating the OCP. There are, however, phenomena in Finnish, such as dialectal epenthesis, which pattern long consonants with short ones rather than with bisegmental consonant clusters. This study provides an Optimality Theoretic analysis for dialectal epenthesis, and shows that the analysis predicts that monosegmental representation is the optimal way of representing long consonants in Finnish as well.
The Relationship Between Consumer Ethnocentrism and Human Values

Abstract The study explores the relationship between human values and consumer ethnocentrism. Schwartz's (1992) framework of human values is used as the basis of the study. Hypotheses linking values and consumer ethnocentrism are developed and tested in samples of consumers drawn from Turkey and the Czech Republic respectively. Findings indicated that the values relationship to consumer ethno-centrism varies across the two countries surveyed. The study also confirmed that “conservation” types of values are positively related to consumer ethnocentrism. However, some of the hypotheses put forward are not empirically supported but they provide new avenues for future re-search.
The bimodal regulation of epidermal growth factor signaling by human Sprouty proteins

Signal transduction through epidermal growth factor receptors (EGFRs) is essential for the growth and development of multicellular organisms. A genetic screen for regulators of EGFR signaling has led to the identification of Sprouty, a cell autonomous inhibitor of EGF signaling that is transcriptionally induced by the pathway. However, the molecular mechanisms by which Sprouty exerts its antagonistic effect remain largely unknown. Here we have used transient expression in human cells to investigate the functional properties of human Sprouty (hSpry) proteins. Ectopically expressed full-length hSpry1 and hSpry2 induce the potentiation of EGFR-mediated mitogen-activated protein (MAP) kinase activation. In contrast, truncation mutants of hSpry1 and hSpry2 containing the highly conserved carboxyl-terminal cysteine-rich domain inhibit EGF-induced MAP kinase activation. The potentiating effect of the full-length hSpry2 proteins on EGF signaling is mediated by the amino-terminal domain and results from the sequestration of c-Cbl, which in turn leads to the inhibition of EGFR ubiquitination and degradation. These results indicate that hSpry2 can function both as a negative and positive regulator of EGFR-mediated MAP kinase signaling in a domain-dependent fashion. A dual function of this kind could provide a mechanism for achieving proper balance between the activation and repression of EGFR signaling.
IS THIS GAME FAIR? THE EMERGENCE OF STATISTICAL REASONING IN YOUNG CHILDREN

Cross cultural investigations were conducted about the representation and development of statistical ideas as students, from three countries, engaged in building sample spaces while playing dice games. The studies took place in Brazil, Israel, and the United States. At each site, small groups of students were videotaped in a regular classroom environment while working with a partner. Student ideas about chance, sampling, sample space, probability, and fairness are described. Reports include student theories about the fairness of the games and what students regarded as evidence for their theories.
Determination of the length of zygomatic implants through computed tomography: establishing a protocol.

OBJECTIVES The aim of this study was to establish and verify an examination protocol using CT to estimate the length of zygomatic implants, thus rendering the surgical process safer and more predictable, and exposing the patient to a minimal level of radiation. METHODS Paracoronal CT scan was carried out on ten dry human crania (n = 20) and the zygomatic implant sites were measured (L(CT)) bilaterally. A standard surgical zygomatic implant placement procedure was carried out and the actual lengths (L(Real)) and clinical lengths (L(Clin)) determined. RESULTS The averages of the L(CT), L(Clin) and L(Real) were 45.73 +/- 4.82 mm, 42.63 +/- 4.33 mm, and 44.73 +/- 4.53 mm, respectively. Student's t-test revealed no statistically significant differences between the L(Real) and L(CT) averages (P = 0.1532), whereas the L(Real) and L(Clin) averages were statistically different (P < 0.0001). CONCLUSIONS The proposed protocol proved to be precise and efficacious in the determination of zygomatic implant length, with the advantage to the patient of a relatively low level of exposure to radiation due to the small quantity of tomographic slices used. Although there were no major repercussions, the clinical probe in the zygomatic implant kit commonly used in this surgical procedure proved to be a rather imprecise tool.
Use of Video Modeling to Increase Positive Peer Interactions of Four Preschool Children with Social Skills Difficulties

Difficulties initiating and maintaining positive social interactions with peers represents a significant problem for many preschool children. The present study sought to evaluate the use of a video modeling intervention for increasing positive peer interactions among four preschool boys who were assessed as having poor social skills. The video modeling intervention was evaluated in a delayed multiple probe across participants design. The video depicted successful entry of a peer in a play routine and maintenance of positive play behavior by the peer. Positive outcomes were achieved for two participants and variable outcomes for the remaining two children. Teachers and parents rated the intervention as acceptable. The results suggest an improvement in the amount of time engaged in positive social interactions with peers for two of the four participants with the onset of the video modeling intervention. The findings are discussed in relation to implications for early childhood practice and future research in the area.
Mothers' and fathers' working models of childhood attachment relationships, parenting styles, and child behavior

Abstract This study addresses the question of whether or not parents' working models of childhood attachments constitute a risk factor for difficulties in current parent-child relations. In a sample of 27 families and their preschool-aged children, mother-child and father-child dyads were observed in separate laboratory play sessions from which ratings of parents' and children's behavior were collected. Working models of attachment were assessed using the Adult Attachment Interview (George, Kaplan, & Main, 1984). Results showed that parents classified as insecure were less warm and provided less structure in interactions with their children than did parents classified as secure. Children of insecure parents were less warm toward their parents than were children of secure parents. Analyses of parents' joint attachment classification showed that insecure women married to insecure men were less warm and provided less structure with their children than did mothers in either the insecure-secure or secure-secure dyads. These findings suggest that, in two-parent families, an insecure working model may be a risk factor for less competent parenting but that the risk is more pronounced when both parents have insecure working models of attachment.
Buscando Trabajo: Social Networking Among Immigrants From Mexico to the United States

The growth of the Latino population in the United States has placed a sharp focus on immigration. Previous research on immigration has taken for granted the existence of immigrant networks. This is a significant oversight given their importance in both conveying social capital and their contribution to the growth of immigrant communities. Using data collected in the summer of 2002, the author looks at the development of an immigrant network in a rural town in northeastern Oklahoma. It is determined that the immigrant network in the community under study includes three distinct yet interconnected subnetworks, a traditional subnetwork, a church subnetwork, and a contract subnetwork. Although each of these secondary networks is made up of different social arrangements, they all provide similar services in a similar manner. The services provided within the greater immigrant network have increased the size, strength, and density of the local immigrant community.
TOCOTRIENOLS ACTIVATE THE STEROID AND XENOBIOTIC RECEPTOR, SXR, AND SELECTIVELY REGULATE EXPRESSION OF ITS TARGET GENES

Vitamin E is an essential nutrient with antioxidant activity. Vitamin E is comprised of eight members, α-, β-, γ-, and δ-tocopherols and α-, β-, γ-, and δ-tocotrienols. All forms of vitamin E are initially metabolized by ω-oxidation, which is catalyzed by cytochrome P450 enzymes. The steroid and xenobiotic receptor (SXR) is a nuclear receptor that regulates drug clearance in the liver and intestine via induction of genes involved in drug and xenobiotic metabolism. We show here that all four tocotrienols specifically bind to and activate SXR, whereas tocopherols neither bind nor activate. Surprisingly, tocotrienols show tissue-specific induction of SXR target genes, particularly CYP3A4. Tocotrienols up-regulate expression of CYP3A4 but not UDP-glucuronosyltransferase 1A1 (UGT1A1) or multidrug resistance protein-1 (MDR1) in primary hepatocytes. In contrast, tocotrienols induce MDR1 and UGT1A1 but not CYP3A4 expression in intestinal LS180 cells. We found that nuclear receptor corepressor (NCoR) is expressed at relatively high levels in intestinal LS180 cells compared with primary hepatocytes. The unliganded SXR interacts with NCoR, and this interaction is only partially disrupted by tocotrienols. Expression of a dominant-negative NCoR enhanced the ability of tocotrienols to induce CYP3A4 in LS180 cells, suggesting that NCoR plays an important role in tissue-specific gene regulation by SXR. Our findings provide a molecular mechanism explaining how vitamin supplements affect the absorption and effectiveness of drugs. Knowledge of drug-nutrient interactions may help reduce the incidence of decreased drug efficacy.
