The Emotional Literacy Support Assistant (ELSA) programme: ELSAs’ and children’s experiences

ABSTRACT This research paper summarises the findings of a small-scale study that explored the experiences of emotional literacy support assistants (ELSAs) and the children with whom they work. Eight ELSAs and seven children were interviewed and a thematic analysis of the transcripts elicited key themes. The findings indicated that the ELSA–child relationship is central to both ELSAs’ and children’s experiences of the ELSA programme, and factors that cultivate or hinder the development of this relationship were identified. This research is central to an understanding of ELSAs’ and children’s perceptions of the ELSA programme and has implications for how the role of ELSAs is conceptualised, and the training and support that educational psychologists provide. The results are discussed with reference to relevant research and suggestions for further research.
6th International Forum of Design as a Process

The aim of this paper is to theoretically discuss the inferential logics of sense attribution to everyday objects. Such discussion takes part of our attempt to explore the possibility of development of a method for systematic research and analysis of the relationship established between users and artifacts in their context of use and specific circumstances. Taking into account the notions of sensible effects, practical bearings, and sense, the argumentation, supported by the Peircean pragmatism, tries to frame their connections with processes of logical mental mediations that emerge when design-agents (e.g., users, designers, and design researchers) deal with everyday objects. The contribution and final considerations of this paper may address issues from the fields of design (practically) and semiotics and design (theoretically and empirically) through possibly enlarging the understanding of the mediation processes, so-called inferential logics of sense attribution.
Coviewing Educational Media: Does Coviewing Help Low-Income Preschoolers Learn Auditory and Audiovisual Vocabulary Associations?

Coviewing media is a practice commonly recommended to parents of young children. However, little is known about how coviewing might scaffold the vocabulary learning of low-income preschoolers. The present study focused on how coviewing educational media influences children’s learning of two different vocabulary associations—auditory-only and audiovisual vocabulary associations. We additionally studied whether children with weaker baseline vocabularies might particularly benefit from coviewing. One hundred twenty-eight low-income preschoolers viewed five educational media clips either with an adult coviewer or alone. Audiovisual and auditory vocabulary associations were then assessed. Results show that coviewing did not support vocabulary learning overall but did specifically support the development of auditory-only vocabulary associations for children with weaker baseline vocabularies. This suggests that coviewing may not provide a ubiquitous benefit but rather predicts learning in the mode of coviewer input (auditory) specifically for the children who need additional supports the most.
Collaborative Filtering with Temporal Dynamics with Using Singular Value Decomposition

Nowadays, Collaborative Filtering (CF) is a widely used recommendation system. However, traditional CF techniques are harder to make fast and accurate suggestions due to changes in user preferences over time, the emergence of new products and the availability of too many users and too many products in the system. Therefore, it becomes more important to make suggestions that are both fast and take the changes in time into consideration. In the presented study, a new method for providing suggestions customized according to the users' preference and taste as they change over time was developed. By combining the time-dependent changes through the SVD (Singular Value Decomposition), a faster suggestion system was developed. Thus, an attempt was made to enhance product prediction success. In the present study all techniques on Netflix data and the results were compared. The results obtained on the accuracy of the predicted ratings were found out to be promising.
PLAUSIBILITY ORDERINGS IN DYNAMIC GAMES

In this paper we explore game-theoretic reasoning in dynamic games within the framework of belief revision theory. More precisely, we focus on the forward induction concept of ‘common strong belief in rationality’ (Battigalli and Siniscalchi (2002) and the backward induction concept of ‘common belief in future rationality’ (Baltag et al. 2009; Perea 2014). For both concepts we investigate whether the entire collection of selected belief revision policies for a player can be characterized by a unique plausibility ordering. We find that this is indeed possible for ‘common strong belief in rationality’, whereas this may be impossible in some games for ‘common belief in future rationality’.
Biprojectivity and biflatness of amalgamated duplication of Banach algebras

Let [Formula: see text] and [Formula: see text] be two Banach algebras such that [Formula: see text] is a Banach [Formula: see text]-bimodule with the left and right compatible action of [Formula: see text] on [Formula: see text]. Let [Formula: see text] be a strongly splitting Banach algebra extension of [Formula: see text] by [Formula: see text]. We show that (super) amenability of [Formula: see text] implies (super) module amenability of [Formula: see text] and (super) amenability [Formula: see text]. We investigate biprojectivity and biflatness of [Formula: see text] in the some especial cases. We also give some results related to module biprojectivity and module biflatness of [Formula: see text], when [Formula: see text] is biprojective or biflat.
DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR THE CHROMATOGRAPHIC PURITY OF LERCANIDIPINE HYDROCHLORIDE IN TABLET DOSAGE FORM

Objective: To simple, precise and accurate method and to perform validation for the chromatographic purity of Lercanidipine hydrochloride in tablets. Methods: An isocratic HPLC analysis was developed on Waters Xterra RP18 column (150 cm x 4.6 mm, 5µ). The compound was separated with the mixture of potassium phosphate buffer pH 3.0 containing 0.1% triethylamine; the pH of the buffer solution was adjusted with ortho phosphoric acid and acetonitrile in the ratio of 55:45 v/v as the mobile phase at flow of 1.0 mL per minute. UV detection was performed at 240 nm using photodiode array detection. Results: The retention time was found to be 9.2 minute. The system suitability parameters such as theoretical plate count, tailing and percentage RSD between six standard injections were within the limit. The method was validated according to ICH guidelines. Calibrations were linear over the concentration range of 0.04-150 µg per mL as indicated by correlation coefficient (r) of 0.999. The robustness of the method was evaluated by deliberately altering the chromatographic conditions. Conclusion: The developed method can be applicable for routine quantitative analysis of Lercanidipine tablets in pharmaceutical formulations.
Variance in spermatozoa number among Apis dorsata drones and among Apis mellifera drones

Ces dernieres annees des donnees differentes concernant le nombre moyen de spermatozoides par mâle ont ete publiees. Les nombres varient entre 1,2 x 10 6 et 2,4 x 10 6 (Tab. I), les valeurs individuelles variant entre 0,22 x 10 6 et 2,65 x 10 6 (Tan et al. 1996, Tab. IA). A cause de ces ecarts eleves, de nouveaux comptages ont ete effectues. A l'aide d'un filet 20 mâles ont ete captures au moment du vol des mâles a une faible distance du nid et 25 autres sur un lieu de rassemblement de mâles (LRM). Sur le lieu de rassemblement nous avions attache sous la fausse reine (leurre) un fil couvert de colle a insecte. Les mâles qui, au cours du vol se collaient les ailes au fil, tombaient au sol et pouvaient etre ramasses. Les comptages de spermatozoides ont ete faits selon le processus habituel: apres le montage des vesicula seminalis, les spermatozoides ont ete rinces dans 0,5 mL de solution de Ringer, tues en ajoutant 4,5 mL d'eau distillee, puis comptes dans un hemocytometre. Nous avons obtenu les valeurs suivantes: 1,19 x 10 6 ± 0,25 x 10 6 spermatozoides chez les mâles pres du nid et 1,59 x 10 6 ± 0,18 x 10 6 chez les mâles du LRM. (Tab. IA). La difference entre les deux lieux etait hautement significative et la variation interindividuelle du nombre de spermatozoides etait significativement plus forte chez les mâles proches du nid que chez ceux du LRM. Les nombres de spermatozoides publies varient fortement, la moyenne se situant entre 4,0 millions et 11,9 millions. Nous discutons les causes possibles de ces differences Il semble improbable qu'elles soient dues a des erreurs methodologiques, car on trouve aussi des differences du meme ordre de grandeur chez le meme auteur. C'est avant tout les differences liees au milieu qui sont responsables des variations. La saisonnalite et les conditions de soin des mâles pourraient influencer la maturation des spermatozoides et etre a l'origine des differences observees. On discute dans quelle mesure le succes reproductif des mâles depend des differences individuelles du nombre de spermatozoides par mâle.
Area under the ROC curve by bubble-sort approach (BSA)

A new approach to area under ROC curve (AUC) evaluation is introduced and compared with the current methods. The main idea is based on the Bubble-Sort method. It advantages from the approach to the qualitative dependent variable which is used as the ordinal (and not nominal) variable in comparison to the classical approach. For binary output data the algorithm reaches the same complexity and values as the other methods. For multi-class classification the complexity differs from the classical approaches and the BSA values of AUC don't fail in the special cases as the current methods do.
Lessons from Contextual Bandit Learning in a Customer Support Bot

In this work, we describe practical lessons we have learned from successfully using contextual bandits (CBs) to improve key business metrics of the Microsoft Virtual Agent for customer support. While our current use cases focus on single step einforcement learning (RL) and mostly in the domain of natural language processing and information retrieval we believe many of our findings are generally applicable. Through this article, we highlight certain issues that RL practitioners may encounter in similar types of applications as well as offer practical solutions to these challenges.
Organizational Leadership - The Strategic Role of the Chief Exec

The owner of a company will want to directly or through the medium of professional executive management to control the operation of that company. Placing a distinct and separate authority at the top of the organization, is not leadership as commonly understood by many. Rather, it is a command that gives legitimate expression to the role of management over the function of leadership. The focus of this paper is on the strategic role performed by the chief executive in providing the embodiment of vision, executive management, and control toward organizational leadership.
Margin Matters: Towards More Discriminative Deep Neural Network Embeddings for Speaker Recognition

Recently, speaker embeddings extracted from a speaker discriminative deep neural network (DNN) yield better performance than the conventional methods such as i-vector. In most cases, the DNN speaker classifier is trained using cross entropy loss with softmax. However, this kind of loss function does not explicitly encourage inter-class separability and intra-class compactness. As a result, the embeddings are not optimal for speaker recognition tasks. In this paper, to address this issue, three different margin based losses which not only separate classes but also demand a fixed margin between classes are introduced to deep speaker embedding learning. It could be demonstrated that the margin is the key to obtain more discriminative speaker embeddings. Experiments are conducted on two public text independent tasks: VoxCeleb1 and Speaker in The Wild (SITW). The proposed approach can achieve the state-of-the-art performance, with 25% ~ 30% equal error rate (EER) reduction on both tasks when compared to strong baselines using cross entropy loss with softmax, obtaining 2.238% EER on VoxCeleb1 test set and 2.761% EER on SITW core-core test set, respectively.
Tabula Nearly Rasa: Probing the Linguistic Knowledge of Character-level Neural Language Models Trained on Unsegmented Text

Abstract Recurrent neural networks (RNNs) have reached striking performance in many natural language processing tasks. This has renewed interest in whether these generic sequence processing devices are inducing genuine linguistic knowledge. Nearly all current analytical studies, however, initialize the RNNs with a vocabulary of known words, and feed them tokenized input during training. We present a multi-lingual study of the linguistic knowledge encoded in RNNs trained as character-level language models, on input data with word boundaries removed. These networks face a tougher and more cognitively realistic task, having to discover any useful linguistic unit from scratch based on input statistics. The results show that our “near tabula rasa” RNNs are mostly able to solve morphological, syntactic and semantic tasks that intuitively presuppose word-level knowledge, and indeed they learned, to some extent, to track word boundaries. Our study opens the door to speculations about the necessity of an explicit, rigid word lexicon in language learning and usage.
The predictive characteristic of the social sentiment on the stock market: Twitter and the stock trend

The study analysed the relationship between the stock return and the investors’ sentiment. The sentiment data has been collected through Twitter, by recording tweets containing a cashtag with the ticker of the companies. Two measures have been implemented to categorise the sentiment. The data gathered shows a large increase of the usage of Twitter by investors. The hypotheses have been tested using the vector autoregression model (VAR) and the causal relationship between the two variables is evaluated with the Granger causality test. The findings reject the possibility of one direction of the causal relationship, thus the investors’ sentiment fails to affect the return of the stocks. However the results show a significant causal relationship in the opposite direction, thereby the stock returns seem to affect significantly the investors’ sentiment. Furthermore, evidence from the VAR model suggests that some stocks do not follow the random walk of the returns, but there is a correlation between the stock returns in a short period. In addition, investors tend to believe in certain pattern of the stock returns, thus they themselves do not believe in the random walk. In conclusion, the sentiment data cannot be exploited to build a trading strategy aimed at forecasting the stock price.
Optimization Model of Transit Signal Priority Control for Intersection and Downstream Bus Stop

Transit signal priority has a positive effect on improving traffic condition and level of transit service in the urban area. In this paper, a passenger-based transit signal priority (TSP) optimization model is formulated to optimize intersection signal phasing based on minimizing accessibility-based passenger delay at the intersection and increased waiting-delay at the downstream bus stop simultaneously. Genetic Algorithm is utilized to calculate passenger-based optimization model that is calibrated by evening rush hour actual traffic data (17:30–18:30, October 13th–October 15th, 2015) along Shuiximen Boulevard in Nanjing, China. The performance of the proposed optimization model in decreasing delay and improving system reliability is simulated and evaluated by VISSIM-based simulation platform, and the results illustrate that the proposed optimization model presents promising outcomes in decreasing accessibility-based passenger delay at intersection (average reduction of 12%) and passenger waiting-delay at downstream bus service stop (average reduction of 18%) compared with traditional vehicle-based TSP optimization method in rush hour.
Life-Cycle Equilibrium Unemployment

This paper extends the job creation–job destruction approach to the labor market to take into account a deterministic finite horizon. As hirings and separations depend on the time over which investment costs can be recouped, the life-cycle setting implies age-differentiated labor-market flows. While search by the unemployed falls with age, the separation rate is rather U-shaped over the life cycle. Worker heterogeneity in the context of undirected search implies an intergenerational externality, which is not eliminated by the Hosios condition. We show that age-specific policies are required to attain the first-best allocation.
Eigenstructure-preserving scheme for a hyperbolic system

A hyperbolic system must have a set of linearly independent eigenvectors and corresponding real eigenvalues. In numerical simulations, however, the eigenvalues can be complex because truncation errors pollute a characteristic polynomial of the hyperbolic system. Here we propose an eigenstructure-preserving scheme which always generates the real eigenvalues, even in discrete level. Although the eigenstructure is discussed in a non-conservative formulation, the proposed scheme is locally conservative owing to the skew-symmetric operators.
Predictive Control of a T-type Inverter in Wind Energy Conversion Systems

A new controlling method of three level inverters is proposed in this paper. Three-level T inverters are widely used in industry for high-power, medium-voltage power conversion and drives. Topics related to power losses due to commutation and quality of the output current is relevant issues in this power range. The neutral-point balancing problem in this topology is another subject that has been studied in recent years. Among the most common control methods for this converter, the literature states are non linear techniques, like hysteresis control, and linear methods, like the use of PI controllers in conjunction with pulse width modulation. The general predictive control scheme is applied here to the inverter. The behavior of the system is predicted for each possible switching state of this kind of inverter. The switching state that minimizes a given cost function is selected to be applied during the next sampling interval following the same strategy. Keywords-predictive control; T-type inverter; grid connected
Production of Polyhydroxyalkanoate (PHA) by a Moderately Halotolerant Bacterium Klebsiella pneumoniae U1 Isolated from Rubber Plantation Area

Polyhydroxyalkanoates (PHAs) are polymers which are produced and degraded by many strains of bacteria. They have properties similar to polypropylene, which is a commonly used petrochemical-based plastic. In the present study, five different bacterial strains were isolated from rubber plantation area, of which only one isolate (U1) was able to produce PHA. Screening for PHA was done by Sudan Black B staining and Nile Blue A staining. The strain U1 produced PHA when cultivated in media with different carbon and nitrogen sources, and the optimal carbon-nitrogen source combinations for PHA production was found. PHA extraction was carried out by sodium hypochlorite digestion method. 16S rRNA analysis showed that the PHA-producing bacterium had maximum sequence similarity with Klebsiella pneumoniae. PHA was analysed by UV spectrophotometry and characteristic functional groups were identified by FTIR spectroscopy. In this study, Klebsiella pneumoniae has shown an ability to produce PHAs using different substrates in acidic and halophilic conditions. Therefore, by optimising the process of production, Klebsiella pneumoniae can be used to produce bioplastics in commercially significant amounts.
Reduction of frequency-dependent light shifts in light-narrowing regimes: A study using effective master equations

Alkali-metal-vapor magnetometers, using coherent precession of polarized atomic spins for magnetic field measurement, have become one of the most sensitive magnetic field detectors. Their application areas range from practical uses such as detections of NMR signals to fundamental physics research such as searches for permanent electric dipole moments. One of the main noise sources of atomic magnetometers comes from the light shift that depends on the frequency of the pump laser. In this work, we theoretically study the light shift, taking into account the relaxation due to the optical pumping and the collision between alkali atoms and between alkali atoms and the buffer gas. Starting from a full master equation containing both the ground and excited states, we adiabatically eliminate the excited states and obtain an effective master equation in the ground-state subspace that shows an intuitive picture and dramatically accelerates the numerical simulation. Solving this effective master equation, we find that in the light-narrowing regime, where the line width is reduced while the coherent precession signal is enhanced, the frequency-dependence of the light shift is largely reduced, which agrees with experimental observations in cesium magnetometers. Since this effective master equation is general and is easily solved, it can be applied to an extensive parameter regime, and also to study other physical problems in alkali-metal-vapor magnetometers, such as heading errors.
