The importance of social interaction activities in the teaching-learning process of English as a Foreign Language

This research was conducted in a state school of Goiânia, in Goiás, Brazil, with fifteen students of a third-year group of high school, in 2014. The main ideas that led this study revolve around the importance of interaction in the English language teaching-learning process, the presence of the other and students’ autonomy/selfregulation. The theoretical basis of this research derives from Bakhtinian dialogism (BAKHTIN, 1993, 2003; BARROS, 1997; BRAIT, 2005), Vygotskian sociointeractionism (VYGOTSKY, 1978; MOLL, 1990; LANTOLF; APPEL, 1994; REGO, 1995) and Freirean thoughts (FREIRE, 1996, 2005) about positioning students as agents of their own learning. The general objectives were: to verify the learners-participants’ perceptions regarding the teaching-learning process of English, before and after the interventions; to observe how different forms of social interaction (T-S, T-Ss, S-T, S-S, Ss-Ss, Ss-T) can interfere in English classes of a third-year group from a state school; and to describe how the teacher-researcher perceives the experience of teaching English with its focus on social interaction. The methodology used is qualitative action research (THIOLLENT, 1986; ENGEL, 2000; MELLO; REES, 2011) and the instruments used to generate the data were questionnaires, field notes and interviews. The outcomes show that the learners could conceive English as a language possible to be appropriated by them, used to communicate, and they could also recognize the importance of the other in the teachinglearning process. Besides that, the teacher-researcher could perceive that interactive and effective classes were possible in that public school.

From Cloaks and Traps to Sabotage: Design Mechanisms for Capturing Value from Knowledge

Knowledge is a source of competitive advantage for organizations but its public good character makes attempts at expropriation difficult to detect and guard against. While prior work has considered legal, economic, and social mechanisms of securing knowledge-based competitive advantage, our contribution lies in identifying how organizations can prevent expropriation of their knowledge by strategically manipulating its manifestations (e.g., routines, blueprints, prototypes, or products). We derive six theoretically distinct types of knowledge manifestation that can be used for these ends, consider their impacts on the awareness, motivation, and capability of a counterparty seeking to expropriate the focal knowledge, and organize them into a novel two-dimensional conceptual framework for comparison. By doing so, we add design mechanisms to the toolbox of isolating mechanisms that can be used strategically to capture value from knowledge. This addition opens up a new channel through which organizations can endogenously shape appropriability regimes and calls scholarly attention to knowledge manifestations as an important unit of analysis for understanding organization, innovation and strategy.
for the degradation of CF 4 to ethanol by electro-scrubbing

Remediation of electronic gas CF4 by using commercially available technologies ended up with another kind of greenhouse gas and corrosive side products. This investigation aimed to develop CF4 removal at room temperature with formation of useful product by attempting an electrogenerated Cu[Ni(CN)4] mediator. In the initial electrolysis of bimetallic complex at anodized Ti cathode demonstrated the Cu[Ni(CN)4] formation, which was confirmed by additional ESR results. The degradation of CF4 followed mediated electrochemical reduction (MER) by electrogenarated Cu[Ni(CN)4]. The removal efficiency of CF4 was achieved 95% by this present electroscrubbing process at room temperature. Through the spectral results of online and offline FTIR analyzer either in gas or in solution phase demonstrated that the formed product during the removal of CF4 by electrogenerated Cu[Ni(CN)4] at electroscrubbing was ethanol (CH3CH2OH) with small amount of trifluoroethane (CF3CH3) intermediate.
Free surface flow driven by a rotating end wall in a stationary cylinder : Structure of the axisymmetric baseflow

We study the steady free-surface flow of a viscous liquid layer contained in a cylinder with a rotating bottom and a fixed lateral wall. When the disk rotates at large speed, the free surface deforms strongly and three-dimensional instability patterns (rotating polygons) or sloshing motions can arise. In order to get some insight on their formation mechanisms, a study of the axisymmetric base flow is carried out numerically. The flow structure consists of a well-known central fluid column entrained in a motion of solid-body rotation at the disk angular velocity. The fluid region situated at the periphery reveals a complex structure as it is found to be surrounded by four boundary layers. This leads us to discuss the relevance of existing base-flow models used for instability studies of this flow configuration.

Corporate Attribute of Board Size and Market Value of Firms in the Nigerian Chemical and Paints Industry

This study examines the relationship between corporate attribute of board size and market value of firms in Nigerian chemical and paints industry. A sample of six companies was used for the period of 2004 to 2012. The study uses board size as corporate governance attribute while market price of shares was used to proxy market value of equity. Using correlation and multiple regression analysis, the results of the study shows that board size (BS) has insignificant and negative impact on market value of equity implying that increasing the number of directors on the board decreases the market value of equity. This suggests that the industry should maintain a small but an effective board capable of exercising better control and monitoring of management activities.
Brief Communication : Nearly balanced glaciers in the Hunza catchment ( Karakoram ) since the 1970 s

Previous geodetic estimates of mass changes in the Karakoram revealed balanced budgets or a possible slight 10 mass gain since the year ~2000. Indications for longer-term stability exist but only very few mass budget analyses are available before 2000. Here, we show based on 1973 Hexagon KH9, ~2009 ASTER, and the SRTM DTM that glaciers in the Hunza River basin (Central Karakoram) were on average in balance or showed slight insignificant mass loss within the period ~1973 – 2009. Heterogeneous behaviour and frequent surge activities were also characteristic for the period before 2000. Surge-type and non-surge-type glaciers showed on average no significantly different mass change values. However, 15 some individual glacier mass change rates differed significantly for the periods before and after ~2000.
Cardiorespiratory Fitness among MBBS Students of Rims , Imphal

Background: Cardio respiratory fitness is the ability of the cardiovascular and respiratory system to supply oxygen to the working muscle tissues and the ability of the muscles to utilize oxygen to produce energy. Maximal Oxygen uptake (VO2max) is the Gold standard to measure the cardio respiratory fitness. High fitness level lowers the risk of many health problems like cardiovascular diseases, Diabetes, Obesity etc. Hence it is required for students to measure and analyze their fitness for a healthy lifestyle. Objective: To determine the cardio respiratory fitness of MBBS students Materials and Methods: In this cross sectional study, 55 healthy volunteers (age 20-29 yrs) were recruited from among the MBBS students of RIMS, Imphal. Cardio respiratory fitness in terms of VO2max was assessed by the Bruce Protocol treadmill test. Results: The mean VO2 max was 41.3471±6.80 ml/kg/min. It was found that the mean VO2max of the students who exercise regularly (n=28;45.74±4.8ml/kg/min) was significantly higher than students who don’t(n=27;36.08±4.7ml/kg/min) [p=. 000] . Also ,the VO2 max of males (n=35;42.80±6.8ml/kg/min)was higher than females(n=20;38.79±6.0ml/kg/min) [p=. 029]. Categorizing them in the fitness scale, exercising students fall on and above the ‘good’ level and most of the students who don’t exercise fall on and below the ‘Fair’ level. Conclusion: The study shows that students who regularly exercise have a better cardiorespiratory fitness. This shows that regular exercise is important to achieve a healthier cardiorespiratory fitness as well as overall health.
Bård Misund and Klaus Mohn INVESTMENT AND UNCERTAINTY IN THE INTERNATIONAL OIL AND GAS INDUSTRY

Overview This paper presents a study of the impact of uncertainty on oil and gas investment in a period of market turbulence and industrial restructuring. Investment theory is combined with modern econometric procedures to test the impact of industrial upheaval on total investment expenditures in the oil and gas industry. A Q model of investment (Tobin 1969) is derived and augmented with measures for both financial market risk and industryspecific risk. Applying modern panel data estimators on a data set covering 170 companies over the period 1992-2005, our approach draws on recent micro-econometric research of the relation between investment and uncertainty.
Pro- C congruence properties for groups of rooted tree automorphisms

We propose a generalisation of the congruence subgroup problem for groups acting on rooted trees. Instead of only comparing the proﬁnite completion to that given by level stabilizers, we also compare pro- C completions of the group, where C is a pseudo-variety of ﬁnite groups. A group acting on a rooted, locally ﬁnite tree has the C -congruence subgroup property ( C -CSP) if its pro- C completion coincides with the completion with respect to level stabilizers. We give a suﬃcient condition for a weakly regular branch group to have the C -CSP. In the case where C is also closed under extensions (for instance the class of all ﬁnite p -groups for some prime p ), our suﬃcient condition is also necessary. We apply the criterion to show that the Basilica group and the GGS-groups with constant deﬁning vector (odd prime relatives of the Basilica group) have the p -CSP.
“On a discrete time risk model with time-delayed claims and a constant dividend barrier”

In this paper a compound binomial risk model with a constant dividend barrier is considered. Two types of individual claims, main claims and by-claims, are defined, where one main claim is dependent with its associated by-claim and the settlement of the by-claim may be delayed for one time period under a certain probability. Formulae for calculating the expected present value of dividend payments up to the time of ruin are provided for discrete-type individual claims. The dividends-penalty identity is then derived. Finally explicit expressions for the corresponding results are obtained for two classes of claim size distributions.
Title Device-independent dimension test in a multiparty

Adevice-independent dimension test for a Bell experiment aims to estimate the underlyingHilbert space dimension that is required to produce givenmeasurement statistical data without any other assumptions concerning the quantum apparatus. Previous workmostly deals with the two-party version of this problem. In this paper, we propose a very general and robust approach to test the dimension of any subsystem in amultiparty Bell experiment. Our dimension test stems from the study of a newmultiparty scenariowhichwe call prepare-and-distribute. This is like the prepare-andmeasure scenario, but the quantum state is sent tomultiple, noncommunicating parties. Through specific examples, we show that our test results can be tight. Furthermore, we compare the performance of our test to results based on known bipartite tests, andwitness remarkable advantages, which indicates that our test is of a truemultiparty nature.We conclude by pointing out thatwith some partial information about the quantum states involved in the experiment, it is possible to learn other interesting properties beyond dimension.
Performance Analysis of Single Stage Boost Inverter Using Quasi-Z Source Technique

Quasi-Z-source inverter (QZSI) is a single stage power converter derived from the Z-source inverter topology, employing an impedance network which couples the source and the inverter to achieve voltage boost function. A new carrier based pulse width modulation (PWM) strategy for the QZSI which gives a significantly high voltage gain compared to the traditional PWM techniques is implemented. This technique employs triangular carrier wave and two dc signals along with two sine waves, with which the simple boost control for the shoot-through states is integrated to obtain an output voltage boost . Z source inverter is a new inverter that can be implemented in all types of power conversion. The circuit topology is based on modified voltage fed quasi z source inverter which suits to the light load or the heavy load and is fit for the resistive capacitive or inductive load. The evolution of renewable energy is being increased because of increasing price of fossil fuels and the growing problem of global warming.With great research, alternative renewable energy sources such as wind, water, bio-mass, geothermal and solar energy have been explored for electric power generation. Among the renewable energy sources, the solar energy is being widely utilized because of the free fuel, abundance, little maintenance and sustainability of solar radiant energy. Electrical energy is directly generated from the solar energy through the photovoltaic (PV) cells. In PV based power conditioning systems, the interface converter system acts as a key component. The impedance source inverter (ZSI) is employed as the interfacing converter conventionally.

Moments of truncated skew-normal / independent distributions

In this work we consider the problem of nding the moments of a doubly truncated member of the class of skew-normal/independent (TSNI) distributions. We obtained a general result and then use it to derive the moments in the case of doubly truncated versions of skew-normal, skew-t, skew-slash and skew-contaminated normal distributions. Many properties of the TSNI family are studied, inference procedures are developed and a simulation study is performed to assess the procedures. An application in the context of censored regression models is also provided.

PTC & B In vitro Screening and Optimization of IAA Production from Plant Growth Promoting Rhizobacteria Burkholderia cepacia UPMB 3

Burkholderia cepacia UPMB3 is an important plant growth promoting rhizobacteria isolated from oil palm rhizosphere which is considered to promote plant growth directly or indirectly. The IAA was extracted, purified, detected and confirmed by thin layer chromatography analyses f r o m t h e strain UPMB3 of B. cepacia. Rf value was compared with the authentic IAA. Maximum 50 μg/ml IAA was produced in the medium supplemented with 4 mg/ml L-tryptophan, under shaken conditions at 150 rpm in seven days incubation at pH 7. The bacterial extract significantly influenced the growth of oil palm seedlings producing shoot, root, leaf and leaf length compared to control.
Dynamic Query RePlanning Using QOOP

Modern data processing clusters are highly dynamic – both in terms of the number of concurrently running jobs and their resource usage. To improve job performance, recent works have focused on optimizing the cluster scheduler and the jobs’ query planner with a focus on picking the right query execution plan (QEP) – represented as a directed acyclic graph – for a job in a resource-aware manner, and scheduling jobs in a QEP-aware manner. However, because existing solutions use a fixed QEP throughout the entire execution, the inability to adapt a QEP in reaction to resource changes often leads to large performance inefficiencies. This paper argues for dynamic query re-planning, wherein we re-evaluate and re-plan a job’s QEP during its execution. We show that designing for re-planning requires fundamental changes to the interfaces between key layers of data analytics stacks today, i.e., the query planner, the execution engine, and the cluster scheduler. Instead of pushing more complexity into the scheduler or the query planner, we argue for a redistribution of responsibilities between the three components to simplify their designs. Under this redesign, we analytically show that a greedy algorithm for re-planning and execution alongside a simple max-min fair scheduler can offer provably competitive behavior even under adversarial resource changes. We prototype our algorithms atop Apache Hive and Tez. Via extensive experiments, we show that our design can offer a median performance improvement of 1.47× compared to state-of-the-art alternatives.
Growth, Physiological and Biochemical Responses of two Greek Cotton Cultivars to Salt Stress and their Impact as Selection Indices for Salt Tolerance

Soil salinity is a major constrain of crop productivity. Upland cotton (Gossypium hirsutum L.) is an important fiber crop worldwide and a major agricultural product in Greece. Two commercial cotton cultivars (‘Hersi’ and ‘ST 318’) were studied to compare their response under non-saline and saline conditions in a greenhouse experiment. Salt stress on plants was imposed by two different approaches: a gradual and an initial acclimatization to a non-lethal NaCl concentration (150 mM). To explore salt stress responses, growth (height of plants, roots, shoots and leaves dry weight, reproductive shoots, Salinity Sensitivity Index), gas exchange (Photosynthetic rate, Stomatal conductance, Transpiration rate and Water Use Efficiency) and biochemical parameters (proline, H2O2 and MDA content), were examined as well as ion homeostasis. ‘Hersi’ had significantly higher dry weight of roots, shoots and leaves, lower salinity sensitivity index of roots compared to ‘ST 318’. In this regard, it appears that ‘Hersi’ cultivar performed better than ‘ST 318’ to increased salinity conditions, due to better control of gas exchange parameters and K+/Na+ homeostasis as well as better membrane integrity. Furthermore, the gradual acclimatization to the 150 mM NaCl concentration had a milder effect on both cultivars compared to the initial acclimatization. ********* In press - Online First.

FA ] 2 J ul 2 01 0 Duality in reconstruction systems ∗ †

We consider the notion of finite dimensional reconstructions systems (RS’s), which includes the fusion frames as projective RS’s. We study erasures, some geometrical properties of these spaces, the spectral picture of the set of all dual systems of a fixed RS, the spectral picture of the set of RS operators for the projective systems with fixed weights and the structure of the minimizers of the joint potential in this setting. We give several examples.
Radecka BUILDING SEMANTIC USER PROFILE FOR POLISH WEB NEWS PORTAL

The aim of this research is to construct meaningful user profiles that are the most descriptive of user interests in the context of the media content that they browse. We use two distinct state-of-the-art numerical text-representation techniques: LDA topic modeling and Word2Vec word embeddings. We train our models on the collection of news articles in Polish and compare them with a model built on a general language corpus. We compare the performance of these algorithms on two practical tasks. First, we perform a qualitative analysis of the semantic relationships for similar article retrieval, and then we evaluate the predictive performance of distinct feature combinations for user gender classification. We apply the algorithms to the real-world dataset of Polish news service Onet. Our results show that the choice of text representation depends on the task – Word2Vec is more suitable for text comparison, especially for short texts such as titles. In the gender classification task, the best performance is obtained with a combination of features: topics from the article text and word embeddings from the title.
