Academic e-tandems as a strategy for English language learning in a Mexican university

E-tandems, or virtual synchronous exchanges, offer opportunities for language learners to practice their skills with native speakers. While they are regularly conducted informally, some institutions are exploring their academic use. This paper reports on the experience of eight students who were learning English at a public university in Mexico. They connected via Skype with a group of peers who were taking a Spanish course in the United Kingdom. Data sources included field notes taken during the e-tandem session, a follow-up survey and a focus group. Participants reported feeling motivated and excited about meeting students from another country. They practiced their oral language skills and received feedback directly from native speakers. Their learning included nonverbal communication, such as hand gestures. Participants discovered cultural differences but also common ground with their peers. The e-tandem experience was an effective strategy for foreign language learning.
On the use of 1,3-diphenylisobenzofuran (DPBF). Reactions with carbon and oxygen centered radicals in model and natural systems

Abstract1,3-diphenylisobenzofuran (DPBF) is a fluorescent molecule which possesses a highly specific reactivity towards singlet oxygen (1O2) forming an endoperoxide which decomposes to give 1,2-dibenzoylbenzene. This reaction between DPBF and 1O2 can be followed by measuring the decrease in fluorescence intensity of DPBF. In order to check the specificity of DPBF toward free radicals a series of experiments was carried out in Triton-X micelles and in natural systems (rat liver microsomes), in which DPBF was reacted with hydroxy (HO•), alkyloxy (RO•), alkylperoxy (ROO•), and C-centered radicals (2-cyanoisopropyl radical). In all cases, the DPBF is rapidly transformed to 1,2-dibenzoylbenzene in the case of O-centered radicals and to the corresponding adduct in the case of 2-cyanoisopropyl radical. The experiments in the model systems were also carried out from the chemical point of view and the reaction products were isolated and identified. From the results obtained, it should be stressed that DPBF must be used with caution in complex biological systems for the detection of 1O2, as it also reacts with different radical species.
Communication requirements for future secondary substations to enable DSO functions

Reliable and scalable communication technologies are required to securely integrate and utilise the flexibility offered by different smart grid solutions. Smart secondary substations can play a critical role in enabling the flexibility services for the DSO with more monitoring and control functions being deployed at these substations. However, there are a number of challenges associated with the deployment and integration of communications to enable future DSO functions. This paper defines the key requirements for future secondary substation communications and provides a number of recommendations to address future operator needs. A case study related to the deployment of a Smart Transformer for better utilisation of network assets and voltage regulation is presented to illustrate the applicability of aforementioned requirements.
Plugging into Trados: Augmenting Translation in the Enclave

The National Virtual Translation Center (NVTC) built an SDL Trados Desktop plugin allowing access to a variety of state-of-the-art machine translation (MT) and transliteration services within its enclave. While Trados users in the open environment have had access to several internet-supplied MT services for some time, this has eluded enclave users. NVTC has had access to an MT portal within its enclave featuring several government and commercial engines in a wide variety of languages, and the plugin now enables users to get results from these engines within Trados, when the translation memory threshold is not met for a translation unit (TU). Translators can customize the order of presentation for the various engines for their language, including whether they want the engine at the top of the list to automatically populate target TU halves. In addition, NVTC has added an automated transliteration feature by which a user can highlight a proper name in the source text and ask for it to be transliterated either as a person or place name; the automated transliteration service will then populate the target text with a transliteration according to the appropriate scheme. Together, the MT and transliteration functionality constitute an important advance in the transition from baseline computer-assisted translation (CAT) to augmented translation (AT), where a fuller range of human-language technology (HLT) services are placed at translators' disposal, ideally within the CAT tool itself. In both the translation and transliteration cases, translators can post-edit the automatically produced information directly within Trados. This paper documents the user pilot of the plugin that assessed user acceptance variables such as preferences for specific MT engines and interface configuration options. The pilot results also provide data points that shed light on productivity and quality impacts of post-editing in NVTC’s environment.
Examination of Diurnal Variation at a Non-Sewage Impacted Beach via qPCR and Culture Based Methods

Fecal indicator bacteria concentrations, a measure of water pollution, do not remain static in the environment and can fluctuate both temporally and spatially. Diurnal variation, partially resulting from the effects of UV light, may decrease the density of E. coli, resulting in lower concentrations in the afternoon. Previous studies conducted at 63rd Street Beach in Chicago, IL [1] and North Beach in Racine, WI [2] demonstrated significant diurnal variation using an E. coli standard and culture-based assays. Subsequent studies conducted at sewage-impacted Great Lakes beaches employing molecular assays (qPCR) found that the signal remained stable; it is unknown whether a similar scenario exists at non-sewage impacted beaches. During the summer of 2011, surface water samples were collected in the morning and afternoon (0700 and 1200) and analyzed by both IDEXX/Colilert and qPCR/BioGx SmartBeads/OmniMix HS to determine if temporal variation in E. coli was occurring (n = 29/23, culture/qPCR). Analysis of log-converted data (independent t-test/one-way ANOVA) indicated no significant difference in mean E. coli concentration as determined by morning and afternoon sampling via either method (Colilert/qPCR, p = 0.49/0.09, α = 0.05). Although not statistically significant (p = 0.09) there were 5 of 23 (22%) instances where afternoon qPCR values exceeded morning counterparts; two (10%) when culture-based assays did not show a similar response. The utility of rapid assays lies in their ability to generate results prior to beach opening; temporal or event-based fluctuations should be considered when using molecular assays at non-sewage impacted beaches for regulatory purposes.
Light-induced adsorption and desorption in Methyl-Red-doped liquid crystals: a review

We present a review of the main results reported during about two decades on light-induced phenomena in liquid crystal samples doped by the azo-dye Methyl-Red. The aim is to give a unifying picture of the different observed effects which have been demonstrated to be originated form the competition of light-induced adsorption and desorption phenomena at the illuminated boundary surface. They give rise either to colossal nonlinearity or to light-induced anchoring and memory effects and have a potential interest for photonics applications.
Benefits of very thin PCBM and LiF layers for solution-processed p–i–n perovskite solar cells

Highly efficient p–i–n perovskite solar cells employing a flat and thick CH3NH3PbI3 film and a thin PCBM film are fabricated by the solution-process at low temperature. Through attainment of optimized PCBM thickness and insertion of the LiF interlayer, the unit cell shows 14.1% of overall power conversion efficiency (PCE) with a Jsc of 20.7 mA cm−2, a Voc of 0.866 V, and a FF of 78.3% under AM 1.5G 100 mW cm−2 conditions, while a larger area 10 cell serially connected module (10 × 10 cm2) shows an 8.7% PCE. These PCE values are the highest reported to date for the planar perovskite–PCBM solar cells.
Cyclic limonene dicarbonate as a new monomer for non-isocyanate oligo- and polyurethanes (NIPU) based upon terpenes

Herein we report a very versatile new route to linear as well as cross-linked terpene-based non-isocyanate poly(hydroxyurethanes) (NIPUs) and prepolymers derived from the novel cyclic limonene dicarbonate (CL). The catalytic carbonation of epoxidized limonene with CO2 was monitored in the presence of both homogeneous tetrabutylammonium bromide (TBAB) and heterogeneous silica supported 4-pyrrolidinopyridinium iodide (SiO2-(I)) catalysts. The systematic variation of catalyst type, CO2 pressure and temperature enabled quantitative carbonation in bulk and incorporation of 34.4 wt% CO2 into CL. In contrast to conventional plant-oil-based cyclic carbonates, such terpene-based cyclic carbonates afford much higher CO2 fixation and do not contain ester groups. The absence of ester groups is essential to prevent side reactions during amine curing, such as ester cleavage and amide formation, impairing network formation and causing emission of low molecular weight polyols which can plastify NIPUs. Novel linear NIPUs and prepolymers were obtained by means of CL advancement with diamines such as 1,4-butane diamine (BDA), 1,6-hexamethylene diamine (HMDA), 1,12-dodecane diamine (DADO) and isophorone diamine (IPDA). Molar mass and formation of amine–amine and carbonate end groups were controlled by varying the CL/diamine molar ratio. Curing CL with tri- and polyfunctional amines such as citric acid aminoamides, tris(N-2-aminoethyl)amine, and amine-terminated hyperbranched polyethylenimines (Lupasol®) afforded novel NIPU thermoset resins. With increasing amine functionality of the curing agent, it was possible to increase both stiffness (Young's modulus of 4100 MPa) and glass transition temperatures (62 °C).
A Lattice Attribute-Based Encryption Scheme for Cloud Storage Based on R-LWE Problem

Attribute-Based Encryption (ABE) is generally applied on Cloud Storage to ensure the security and efficient access control of uploaded data. However, with the development of quantum computing, Diffie-Hellman Problem and Discrete Logarithm Problem, which all ABE scheme based on, have been solved. Therefore, anti-quantum ABE schemes become a research hotspot. However, current anti-quantum ABE schemes cannot make attribute revocation. In order to solve these problems, we propose a lattice attribute-based encryption scheme for cloud storage based on R-LWE problem (L-ABE). Firstly, we construct public/secret key pairs based on the hardness of Ring Learning with Error problem (R-LWE) to achieve quantum attack resistance effectively. Secondly, our scheme can achieve attribute revocation to ensure fine-grained access control. Finally, we prove that our scheme can resist chosen plaintext attack.
Socioemotional Mechanisms of Children’s Differential Response to the Effects of Maternal Sensitivity on Child Adjustment

SYNOPSIS Objective . Children differ in the extent to which they reap the benefits of maternal sensitive care or suffer the adverse consequences of insensitive care, and these differences can be accounted for by biological characteristics. However, how susceptible children adapt to maternal sensitivity in ways that either maximize positive development or lead to maladjustment has yet to be determined. Here, we propose a novel model of socioemotional mechanisms by which the joint influences of maternal sensitivity and child biological characteristics influence child adjustment. Design . We propose a theoretical model, in which children’s vagal functioning and polymorphisms in serotonin transporter (5-HTTLPR) and dopamine receptor D4 (DRD4) genes confer susceptibility to the effects of maternal sensitivity on internalizing, externalizing, prosocial and moral behavior via changes in interpersonal strategies for emotion regulation, the threat response system, and empathy. Results . Theoretical and empirical support for the proposed mechanisms are provided. Conclusions . The proposed mechanistic model of susceptibility to maternal sensitivity offers a novel framework of for whom and how children are affected by early maternal care, highlighting multiple reciprocal, interacting influences across genes, physiology, behavior, and the environment.
Human Body Shape Reconstruction from Binary Image Using Convolutional Neural Network

Human body modeling is an important part of virtual try-on. In order to quickly reconstruct the three-dimensional(3D) human body based on the minimum input, we propose a new method for accurate reconstruction of the human body by inputting binary images from either single view or multiple views. We first encode the shape of the human body via Principal Component Analysis (PCA) to extract the low dimensional shape descriptor. Secondly, we design a novel Body Reconstruction Convolutional Neural Network (BRCNN) with two branches, which could capture deep correlated features from different views and merge them. Given the obtained statistical shape space of the human body, we jointly train the BRCNN to learn a global mapping from the input to the shape descriptor which can be then decoded to points cloud for the reconstruction of various body shapes under neutral poses. The experimental results show that compared with the existing human reconstruction technology, the accuracy has been improved by 1.07%, and the prediction results of the two views are better than those from the single view. Further investigation also reveals that the prediction results of the weight-sharing network are better than the network without weight-sharing.
Blind recognition of MIMO-SFBC based on Symbolic eigenvalue*

In the blind recognition of air frequency block code signals, a blind recognition algorithm of MIMO-SFBC based on symbolic eigenvalue was proposed to solve the problems of poor recognition performance and large number of samples under the condition of low SNR. According to the symbol correlation characteristics of different air frequency block codes in frequency domain, the eigenvector sequences of different air frequency block codes are derived, symbolic eigenvalue are estimated by binary hypothesis testing, and different coding types are distinguished by decision tree classification recognition algorithm. Simulation results show that the algorithm does not need prior information such as modulation prediction, and has good recognition performance under low SNR and small sample conditions, and can be applied to engineering fields such as cognitive radio.
Encrucijadas y desafíos de los Estudios Organizacionales Una reflexión desde las perspectivas institucionales

This work seeks to reflect on the current state of organiza­tional studies based on the analysis of major institutional approaches. The diversity of approaches typical of the institutional theory is remarked, ad­dressing two of its most relevant theoretical currents: the new sociological institutionalism and the institutional logics, whose extensive development has fostered a rapprochement between organizational studies and orga­nization theory. This paper studies the advantages of such proximity but also some of its limitations; mainly that organizational studies have been partly absorbed by the study of institutions, neglecting the development of some lines of reflection grounded on Human Sciences. The balance of organizational studies increasingly oscillates between being considered an advanced management course or a specialized sociology class. The first case represents a greater risk for this type of studies in Latin America, given that, among other reasons, they have mainly originated in Adminis­tration schools and departments, which has hindered its development as a private project. The main contribution of this work focuses on the idea that a more effective development of organizational studies could be achieved by strengthening its disciplinary identity in order to build better links with management, sociology and organization theory. We also propose some action lines that represent important challenges for improving the neces­sary conditions to achieve a better development of organizational studies.
PERFIL DA MOBILIDADE LABORAL INTER E INTRAMUNICIPAL NO BRASIL NOS ANOS DE 2000 E 2010 / Profile of inter and intra city labor mobility in Brazil in the years 2000 and 2010

INTRODUÇÃO No Brasil, os fluxos relacionados à mobilidade intermunicipal têm sido estudado com maior frequência. No entanto, merece ser analisado do ponto de vista pessoal, no que diz respeito as características dos indivíduos que realizam esse movimento. A princípio é importante salientar que esse tipo de mobilidade é caracterizado por deslocamentos regulares e cotidianos, entre limites políticos administrativos e tem como influência as atividades de trabalho e/ou estudo (ARANHA, 2005). Conforme Silva (2012), as mudanças nos tipos de deslocamentos populacionais observados nos diferentes espaços do Brasil têm sido mais frequentes. Assim, é importante saber o que influencia a mobilidade das pessoas, sobretudo a mobilidade intermunicipal. Ademais, de acordo com a literatura, é possível que tais fluxos ocasionem reconfigurações nos territórios metropolitanos, mediante diferentes condicionantes que propiciam esse tipo de deslocamento, com distinção inclusive de grupos sociais e valorização do solo dessas áreas que em alguns casos, convivem com moradias populares e condomínios de luxo (CUNHA, 1994; CINTRA et al., 2009; MAGALHÃES; D’ÁVILA, 1996). Embora as áreas metropolitanas sejam os principais cenários da mobilidade intermunicipal (JARDIM, 2001; OLIVEIRA; TAVARES, 2015), as discussões no que
Phosphate adsorption by soils 1. Influence of time and ionic environment on phosphate adsorption

Abstract The influence of reaction time and ionic environments, on phosphate adsorption were studied using one calcareous soil from India, and one calcareous and two latosols from Hawaii. Phosphorus adsorption by soils has a initial rapid phase followed by a slow process. For plant nutrition studies, where emphasis is on P concentration of solutions from which plants derive P, isotherms should be constructed using data obtained after near‐equilibration has been attained. This condition does not obtain in a few hours and may require 6 days or more. Calcium chloride as suspending electrolyte always gave lower phosphate solubility than when KC1 was used as electrolyte. Phosphate retention increased with increasing ionic strength. The necessity for obtaining clear supernatant solutions and the desirability for maintaining reasonable constant equilibrium conditions make 0.01 M CaCl2 a reasonable choice for constructing P sorption isotherms, even though 0.01 M CaCl2 is not representative of Ca concentrations in.
13C NMR spectra of substituted carbazoles and azacarbazoles (β‐carbolines)

13C NMR spectra of a series of derivatives of carbazole and azacarbazole (norharmane or 9H‐Pyrido [3,4‐b]indole) are reported. The dependence of 1H and 13C shieldings on molecular geometry is discussed briefly.
Nutritional Quality Evaluation of Popular Indian Fried Snacks Based on Cowpea

Snacks are small, light, very handy, and simple meals which do not replace main meals. These snacks add to the total food and nutrient intake of individuals. In India people love to eat snacks and considered to be a habit. These snacks are usually chips, namkeens, lightly processed or fried and ready-to-eat food products. This made the processed food industry more dynamic and productive. Resulting all above, gobs of conventional foods especially fried snacks are available in Indian market. Recent years, Indian snack market has undergone various changes due to high competition among multi-national companies which lead to high standards for the regional and small food processers. Local and regional food processors also play an important role through developing distinctive products and flavours by using local and indigenous food produce. With all these contributory factors Indians also have an emotional connection with eating snacks and this continues to drive the market towards growth.

A Tale of Eight Countries or the EU Council Presidency Translator in Retrospect

In this paper, we describe the development of the EU Council Presidency Translator, a machine translation solution first introduced during the EU Council Presidency of Latvia. We further analyze how the EU Council Presidency Translator has been used across seven presiding member states starting from H2’2017 onwards. Our findings show that usage of different translation tools has depended on the technological readiness level of the presiding member state. Nevertheless, Presidency Translator usage statistics indicated an upwards trend in the volume of words translated monthly, suggesting increasing popularity of the machine translation based solution. Our analysis further indicates that the machine translation services are used continuously after the periods of presidencies they were developed for conclude. These findings suggest the usefulness of the Presidency Translator above and beyond the needs of the period of the presidency.
Self-serving recall is not a sufficient cause of optimism: An experiment

A recent experimental literature has documented that people are (sometimes) asymmetric updaters: Good news are over-weighted, relative to bad news. We contribute to this literature with a novel experimental test of a potential mechanism of asymmetric updating, that is, that people recall better the positive than the negative evidence. In our design, this account predicts inflated posteriors regarding some future financial prize. Contrary to that, the average subject (slightly) underestimates the mode of the posterior beliefs about that payoff prospect. Although subjects tend to exhibit self-serving recall (SSR) in that they remember better the positive realizations of a signal in a memory task, this has little effect on their estimates and the extent and direction of the bias. A difficulty to recall accurately, we conclude, is not a sufficient cause for a positivity bias.
