Abstract
We present the first results from an optical reverberation mapping campaign executed in 2014 targeting the active galactic nuclei (AGNs) MCG+08-11-011, NGC 2617, NGC 4051, 3C 382, and Mrk 374. Our targets have diverse and interesting observational properties, including a “changing look” AGN and a broad-line radio galaxy. Based on continuum-Hβ lags, we measure black hole masses for all five targets. We also obtain Hγ and He ii
λ4686 lags for all objects except 3C 382. The He ii
λ4686 lags indicate radial stratification of the BLR, and the masses derived from different emission lines are in general agreement. The relative responsivities of these lines are also in qualitative agreement with photoionization models. These spectra have extremely high signal-to-noise ratios (100–300 per pixel) and there are excellent prospects for obtaining velocity-resolved reverberation signatures.
Facilitating Follow-up of LIGO–Virgo Events Using Rapid Sky Localization
Authors: Chen Hsin-Yu , Holz Daniel E. 
Published: May 2017

Abstract
We discuss an algorithm for accurate and very low-latency (<1 s) localization of gravitational-wave (GW) sources using only the relative times of arrival, relative phases, and relative signal-to-noise ratios for pairs of detectors. The algorithm is independent of distances and masses to leading order, and can be generalized to all discrete (as opposed to stochastic and continuous) sources detected by ground-based detector networks. Our approach is similar to that of BAYESTAR with a few modifications, which result in increased computational efficiency. For the LIGO two-detector configuration (Hanford+Livingston) operating in O1 we find a median 50% (90%) localization of 143 deg2 (558 deg2) for binary neutron stars. We use our algorithm to explore the improvement in localization resulting from loud events, finding that the loudest out of the first 4 (or 10) events reduces the median sky-localization area by a factor of 1.9 (3.0) for the case of two GW detectors, and 2.2 (4.0) for three detectors. We also consider the case of multi-messenger joint detections in both the gravitational and the electromagnetic radiation, and show that joint localization can offer significant improvements (e.g., in the case of LIGO and Fermi/GBM joint detections). We show that a prior on the binary inclination, potentially arising from GRB observations, has a negligible effect on GW localization. Our algorithm is simple, fast, and accurate, and may be of particular utility in the development of multi-messenger astronomy.

Published: May 2017

Since the last century, we have witnessed a steady evolution of advertising techniques in an effort to adapt to the new social context in the market. As a strategic resource, Neuroscience brings a new perspective by allowing you to explore those difficult or verbally unconscious motives behind consumer behaviours. The present work aims to discover the relationship between the emotions induced in audiovisual advertising messages and their impact on the memory of the subjects. To achieve this goal, an experiment was carried out with eight audiovisual advertising messages (six representatives of the basic emotions: joy, surprise, anger, disgust, fear and sadness, and two rational ones that show the technical specifications of the product). Neuromarketing techniques such as the electrical activity of the heart (ECG) and the electrodermal activity (EDA) of the subjects are used, on one hand; and, on the other, a conventional research technique, a questionnaire applied to the subjects that participated in the research. The results show variations in the measures performed in the commercials corresponding to joy, surprise and anger, while for both, remembrance of the message transmitted and activity of the advertiser, the commercial with the best results has been the one regarding sadness, advertisement that has also been considered the most attractive for participating subjects.
Desde el siglo pasado hemos presenciado una evolución constante de las técnicas de comunicación publicitarias en un intento de adaptación a las nuevas realidades sociales del mercado. Como recurso estratégico, la Neurociencia aporta una nueva perspectiva al permitir explorar aquellos motivos difíciles de verbalizar o inconscientes que hay detrás de los comportamientos de los consumidores. El presente trabajo tiene como objetivo descubrir la relación entre las emociones inducidas en los mensajes publicitarios audiovisuales y su impacto en el recuerdo de los sujetos. Para alcanzar este objetivo se ha realizado un experimento con ocho mensajes publicitarios audiovisuales (seis representativos de seis emociones básicas: alegría, sorpresa, ira, asco, miedo y tristeza; y dos racionales) en el que se han utilizado, por un lado, técnicas de Neuromarketing como son la actividad eléctrica cardíaca (ECG) y la actividad eléctrica de la dermis (AED) de los sujetos; y, por otro, una técnica de investigación convencional, un cuestionario aplicado a los sujetos que han participado en la investigación. Los resultados ponen de manifiesto variaciones en las medidas realizadas en los mensajes correspondientes a la alegría, la sorpresa y la ira, mientras que, tanto para el recuerdo sugerido del mensaje trasmitido como para la actividad del anunciante, el anuncio con mejores resultados ha sido el de la tristeza, anuncio que también ha sido considerado el más atractivo para los sujetos participantes.

The purpose of this study is to analyze the perception of students, graduates, and lecturers in relation to systems of formative and shared assessment and to the acquisition of teaching competences regarding communication and the use of Information and Communications Technology (ICT) in initial teacher education (ITE) on degrees in Primary Teaching Physical Education (PTPE) and Physical Education and Sports Science (PESS). An ad hoc questionnaire was applied to a total sample of 1,243 students, 487 graduates and 345 lecturers from 24 Spanish universities that cover most of Spain’s Regional Autonomous Communities. The results from the questionnaires indicate that for all three groups the most relevant element in the assessment process is the teacher-student interaction, and the second most relevant are the competences in interpersonal relationships. Significant differences are also found in practically all the items in the questionnaire between the responses of lecturers and students and between those of students and graduates. In our detailed study of the perceptions of students regarding their competence in ICT, those taking the degree in PTPE perceive a greater use of ICT than those taking the degree in PESS. The same difference was found with students under 22 years of age in relation to the older students. No gender differences were found.La finalidad de este estudio es analizar la percepción del profesorado, alumnado y egresados en relación a los sistemas de evaluación formativa y compartida y a la adquisición de competencias docentes respecto a la comunicación y al uso de las TIC, en la formación inicial en el Grado de Maestro de Primaria (Educación Física) y en el Grado en Ciencias de la Actividad Física y el Deporte (CCAFD). Se ha aplicado una escala diseñada «ad hoc» en una muestra total de 1.243 estudiantes, 487 egresados y 345 profesores de 24 Universidades españolas que abarcan la mayoría de las Comunidades Autónomas. Los resultados indican que para los tres colectivos el elemento más relevante en el proceso de evaluación es la interacción profesores-estudiantes y, en segundo lugar, las competencias en relaciones interpersonales. También que existen diferencias significativas en prácticamente todos los ítems entre los profesores y los estudiantes y entre estos y los egresados. En el estudio pormenorizado de la percepción de las competencias TIC por parte de los estudiantes, los procedentes del Grado de Maestro de Primaria perciben una mayor utilización de las TIC que los de CCAFD; lo mismo ocurre con los menores de 22 años en relación a los más mayores. No se han encontrado diferencias en función del género.
Swept-Source OCT Visualization of Macular Hole Closure in Gas-Filled Eyes
Authors: Li Daniel Q. , Choudhry Netan 
Published: May 2017

BACKGROUND AND OBJECTIVE:
To assess the utility of swept-source optical coherence tomography (SS-OCT) in visualizing macular hole (MH) closure through gas-filled eyes on postoperative day (POD) 1 using a dual scanning protocol.

PATIENTS AND METHODS:
We examined 30 consecutive patients with full-thickness MH who underwent standard vitrectomy with SF6 (25%) gas tamponade between July 2015 and April 2016. SS-OCT imaging was performed using horizontal raster and 16-line radial scans with manual delicate focusing to evaluate MH closure status.

RESULTS:
On POD1, optically clear images with visualization of all retinal layers at the fovea were obtained in 80% of eyes, of which 71% achieved complete MH closure. Reasons for unsuccessful imaging included: hyphema (two eyes), dense cataract (two eyes), and gas meniscus interference (two eyes).

CONCLUSION:
SS-OCT with dual scanning protocol and manual delicate focusing enabled consistent early visualization of foveal architecture for assessment of MH closure through gas-filled eyes.

ABSTRACT
Microorganisms and their by-products play a critical role in pulp and periradicular pathosis. Therefore, one of the main purposes of root canal treatment is disinfection of the entire system of the canal. This aim may be obtained using mechanical preparation, chemical irrigation, and temporary medication of the canal. For this purpose, various irrigation solutions have been advocated. Common root canal irrigants, such as sodium hypochlorite, chlorhexidine, and a mixture of tetracycline, acid, and detergent have been extensively reviewed. The aim of this review was to address the less common newer root canal irrigation solutions, such as citric acid, maleic acid, electrochemically activated water, green tea, ozonated water, and SmearClear.

Published: May 2017

Abstract
The purpose of this study was to find out the level of the listening comprehension strategies that junior secondary school students in Oredo Local Government Area of Edo State use in learning English Language. From a population of six thousand five hundred and thirty four (6534) Junior Secondary 3 students in public schools, a total of six hundred and sixty two (662) students constituted the sample size drawn through the stratified sampling and simple random techniques from six (6) sampled schools. Two instruments titled Listening Comprehension Proficiency Test (LCPT), developed by TOEFL and Listening Comprehension Strategy Questionnaire (LCSQ) adopted from Oxford (1990) Strategy Inventory for Language Learning (SILL) were used to collect the data for the study. The data collected were analysed using descriptive statistics (mean and standard deviation). Results indicated that among the six strategy categories, Metacognitive (M=2.16, SD= .46), had the highest mean, followed by the Cognitive (M=1.97, SD= .34), Compensation (M=1.97, SD=.46), Social (M=1.95, SD=.47) and Memory (M=1.89, SD=.41). Affective (M=1.84, SD=.43) had the lowest mean. On the average, all the variables put together the findings from research question 2 indicates that the subjects had a mean score of 1.96 which is lower than the theoretical mean of 2.0. This indicates that students′ use of listening strategies is low. As a result, the study proposed that learners should be exposed to listening strategy instruction.

Authors: Kabashi Lema , Epstein Ann 
Published: May 2017

AbstractThe purpose of this A-B subject research design was to investigate the efficacy of video self-modeling with video feedback using an iPad to promote social initiation skills in a young child with Autism Spectrum Disorder (ASD). It was hypothesized that the participant would increase social initiations toward peers in an inclusive preschool classroom by viewing a video of himself performing four targeted behaviors. The participant’s paraprofessional and his early childhood special educator implemented the intervention and provided feedback on his performance. Findings of this case study revealed improvements in the four targeted behaviors: approaching, greeting, inviting, and interacting with a peer. As a result of the intervention, the participant demonstrated generalization of target behaviors across settings, peers, items, and activities. In addition, the target behaviors were maintained one month after the intervention was withdrawn. Social validity results from the participant’s parents as well as his paraprofessional and teachers supported efficacy of the intervention.

Abstract
This documents aims to study the progress of the development of two operational structures, it MFIs and SMEs in our country. In this context, this research analyzed the progress and development financial institutions (MFIs) and their impact on the promotion and development of SMEs in Albania. Through performance evaluation of leading MFIs operating in our country, it is examining the potential opportunity and the role they play in increasing the profitability of SME's. The financial industry is considered more important seeing that they contribute to the economic development of the country. As MFIs seek self ongoing funding would successfully realize their business, they should be very careful in the administration of resources through evaluation of financial activity indicators. Analysis of the financial statements of MFIs regulated by special laws and supervised by the Bank of Albania. Analysis of financial and economic indicators of an MFI done through an analysis known as CAMEL reports. CAMEL reports are used as a more efficient decision-making tool for assessing the performance of financial institutions to anticipate the future and their risk. To realize the full information required CAMEL evaluation of data from financial statements, information on operational activity, etc. macroeconomic information. MFIs develop internal and accounting procedures and internal control mechanisms to identify, record and monitor all potential exposure to them. Bank of Albania, in case of failure to meet its obligations and requirements apply supervisory measures, preventive and punitive provided by law. Seen under this perspective, we must qualify for MFIs that have taken in the study are faced restrictions on their financial statements. So with the data available we will try to estimate the financial reports for each IMF review (FED Invest SCA, BESA Found, NOA, Vision Fund Albania, and FAF) and the total system of MFIs in Albania. These results are generated through an empirical analysis of IMFs in Albania and broke the are-consistent with the theory.

Teacher and His/Her Role in Teaching English
Authors: Balla Ervin 
Published: May 2017

Abstract
Teachers play e key role in the process of teaching. In this article it is tried to focus on some of the most important roles that the teacher of English language plays during the difficult process of teaching. The role of the teacher in class is important. In the class teachers are: leaders of the language, thinkers, administrators, surces experts, vigilants, material furnishers, organizers, performers, estimators, listeners and controllers. At the recent literature is posed the question of the ideal teacher, so what makes a good teacher? According to Medgyes P. All the teachers are extraordinary according to their ways and different from eacher other. According to him the concept of the ideal teacher does not fit to a single concept, because many things have to be taken into consideration. Another image of English teacher is the teacher who is expert of the English language. According to Whitaker the English teacher needs to own the subject and to make the students to follow willingly the subject. He not only should own the subject but he should also know how to explain it.
