Páginas web en español para desarrollar la comprensión auditiva

espanolSe sabe que la comprension auditiva en un segundo idioma se puede facilitar mucho escuchando podcasts con transcripciones y viendo videos con subtitulos. Desde 1970, los investigadores en adquisicion de lenguas han estudiado la efectividad de escuchar y leer este input al mismo tiempo. Por ejemplo, Garza (1991) senala un mayor indice de comprension por el uso de los subtitulos. Asimismo, Baltova (1999) indica que leer mientras se escucha es mas beneficioso que solo leer o solo escuchar para adquirir vocabulario porque “la exposicion a la lengua hablada, el texto impreso y la informacion visual convergen hacia el mismo mensaje” (p. 31). Despues de revisar la bibliografia sobre la utilizacion de la audio-lectura, se ofrecera una seleccion de materiales didacticos con audio y texto. Se ha hecho una seleccion de sitios web con audio-lectura y actividades de autocomprobacion. Otros sitios web no cuentan con las actividades y, en este caso, se sugieren algunas que utilizan herramientas de Internet, como generadores de comic. EnglishWe know that listening comprehension in a second language can be improved by listening to podcasts with transcriptions and watching videos with subtitles. Since 1970, second language acquisition researchers have been studying the effectiveness of listening while reading. For example, Garza (1991) finds a higher comprehension rate because of the use of subtitles. Also, Baltova (1999) points out that reading while listening facilitates more vocabulary acquisition than just reading or just listening because “the exposure to spoken language, printed text and visual information all convey the same message” (p. 31). Where possible, we have selected websites with audio-reading and self-check activities. Other websites do not offer these activities, in which case, some are suggested that use Internet tools, such as comic generators.
Predicting student academic performance using multi-model heterogeneous ensemble approach

The purpose of this paper is to empirically investigate and compare the use of multiple data sources, different classifiers and ensembles of classifiers technique in predicting student academic performance. The study will compare the performance and efficiency of ensemble techniques that make use of different combination of data sources with that of base classifiers with single data source. ,Using a quantitative research methodology, data samples of 141 learners enrolled in the University of the West of Scotland were extracted from the institution’s databases and also collected through survey questionnaire. The research focused on three data sources: student record system, learning management system and survey, and also used three state-of-art data mining classifiers, namely, decision tree, artificial neural network and support vector machine for the modeling. In addition, the ensembles of these base classifiers were used in the student performance prediction and the performances of the seven different models developed were compared using six different evaluation metrics. ,The results show that the approach of using multiple data sources along with heterogeneous ensemble techniques is very efficient and accurate in prediction of student performance as well as help in proper identification of student at risk of attrition. ,The approach proposed in this study will help the educational administrators and policy makers working within educational sector in the development of new policies and curriculum on higher education that are relevant to student retention. In addition, the general implications of this research to practice is its ability to accurately help in early identification of students at risk of dropping out of HE from the combination of data sources so that necessary support and intervention can be provided. ,The research empirically investigated and compared the performance accuracy and efficiency of single classifiers and ensemble of classifiers that make use of single and multiple data sources. The study has developed a novel hybrid model that can be used for predicting student performance that is high in accuracy and efficient in performance. Generally, this research study advances the understanding of the application of ensemble techniques to predicting student performance using learner data and has successfully addressed these fundamental questions: What combination of variables will accurately predict student academic performance? What is the potential of the use of stacking ensemble techniques in accurately predicting student academic performance?
Permeance Computation for Determination of Induction Motor Acoustic Noise

The Maxwell pressure is the cause of stator defl ection at the origin of acoustic noise radiated by stator. That is why precise determination of air-ga p radial flux density B g is of prime importance. It could be obtained by finite element method, semi numerical or totally analytic method with computation of magneto motive force and permeance. Slot numbers, eccentricity and saturation affecting acoustic behavior can be included in permeance computation with analytic method.
Self-perception of humor: Evidence for discounting and augmentation effects.

Self-perception theory (Bem 1972) implies that enjoyment of humorous stimuli is inferred by taking into account external factors affecting overt mirth. As a test of this logic, 60 women read 2 equally funny sets of jokes. A laugh track was played in their headphones for 1 of 2 sets of jokes. Although the laugh track had no impact on Ss' mirth, Ss were told that it would facilitate, inhibit or not affect smiling and laughter. As predicted, in a later free-time period when Ss could read the books from which the jokes came, Ss who were told the laugh track increased mirth spent most time time reading the book whose jokes had not been accompanied by laughter (a discounting effect).
Motivations and Barriers to Household Waste Sorting in Reykjavík

Although the Icelandic waste management system has undergone significant changes from the 1990s onwards, and more people than ever before have been stating to engage in household waste sorting, landfilling is still the most widely used management method in Iceland. In 2016, as much as 61% of municipal solid waste (MSW) went to landfill, while only approximately 33% was returned to the production cycle. In the meantime, quantities of per capita MSW were approximately as high as just before the 2008 financial crisis, indicating a strong link between consumption patterns and waste generation. Given that the diversion of household waste from landfill through recycling and other forms of material or energy recovery depends heavily on public participation in waste sorting schemes, the objectives of this study are to explore perceptions of and experiences with systematic approaches to household waste sorting in Reykjavík, and to identify what motivates and inhibits waste sorting at the household-level. To conduct the study, a qualitative method of in-depth interviews with 16 members of households located in Reykjavík was employed. Through thematic analysis, 13 themes could be constructed that were found to be pivotal to the research participants’ decision as to whether or not, and to what extent, to engage in waste sorting. These include historical context, concern for the future of Earth, infrastructure and storage space, personal initiative and effort, consumer culture, informedness, trust and transparency, spillover effects from non-domestic contexts, sense of order, monetary incentives, environmental impact, recyclability and reusability, and low weight and volume and rare use.
Habituated: A Merleau-Pontian Analysis of the Smartphone

Abstract:This paper offers a phenomenological account of our relationship to our smartphones rooted in the work of philosophers Maurice Merleau-Ponty (1908–1961) and Drew Leder (1954–). We argue that the nature of this relationship has implications for the ways we conceptualize and promote information literacy in the era of mobile ubiquity. After reviewing recent LIS literature on mobile devices in libraries, we discuss Merleau-Ponty’s notion of the habit body and Drew Leder’s development of the Merleau-Pontian concept of incorporation. We then apply these concepts to our use of smartphones, paying particular attention to the incorporation of the smartphone in our bodily habit and what this means for our relationship to the information we access on this device. The paper concludes by considering how the insights from this analysis of the smartphone could be integrated into existing information literacy conversations through the lens of dispositions.

The proposed system is low cost and energy efficient system as employs Raspberry pi controller to receive notices and display on LCD or terminal.
Factores asociados a la incapacidad funcional global luego de transcurrido un año después del traumatismo craneoencefálico

Se estimo la prevalencia de los factores asociados con incapacidad funcional a los seis y doce meses en pacientes con traumatismo craneoencefalico (TCE) atendidos en una unidad de referencia en la Region Metropolitana de Salvador, Bahia, Brasil. Se realizo un estudio de cohorte prospectivo con 307 individuos con TCE de 15 a 65 anos que tuvieron diagnostico confirmado por imagen. Con los datos obtenidos durante el periodo de internacion hospitalaria, se contactaron 242 pacientes a los seis meses del traumatismo y 222 a los 12 meses. El compromiso funcional fue evaluado con la escala de Disability Rating Scale. La prevalencia global de incapacidad funcional (60,3% en la primera evaluacion y 40,5% en la segunda) estuvo asociada significativamente con la edad, la gravedad inicial del TCE y la duracion de la internacion en el hospital, con fatiga, afasia, trastornos de la memoria, atencion y concentracion, alteraciones del equilibrio, paresia y ausencia de consultas con especialistas. La alta frecuencia de incapacidad global a los seis y doce meses de seguimiento, aun en pacientes con traumatismos leves, denota la relevancia del TCE como productor de incapacidades y deficiencias, asi como la necesidad de servicios de seguimiento.
La cooperativa como espacio de realización del derecho de participación de los adultos mayores

The cooperative enterprise is being strengthened in Cuba as part of the political effort to update the Cuban model of economic and social development. That update is happening in an environment of a very aged society, and this factor has to be observed in its broadest dimension. For this reason, the following study has as objective, to value, from a psycho-social-legal perspective, the distinctive elements of the cooperative that make of this a viable space for the realization of the right of participation of the older adults. In order to comply with the proposed objective, methods specific to Legal Sciences were used, such as: legal history, legal doctrine and technical-legal analysis itself, which made possible to deal with some doctrinal and historical considerations on ageing and participation in the legal environment of the elderly, as well as the assessment of the potential of the cooperative for the socio-economic insertion of the elderly, based on the principles of vital continuity and participation that are enshrined in studies on old age.
A Research on data mining using machine learning

Data mining is the mathematical techniques of reading patterns in large sets of data involving methods belonging to the various fields like artificial intelligence, machine learning, and statistics. It is a subfield of computer science. This field is in high demand in the 21st century because it is implementable in all fields of science, social media and business. We are using the concepts of machine learning to train our system against a set of English phrases and words which may have weight . This weight is how we decide whether the phrases have a positive, negative or neutral net sentiment ratio. We then read data from sources and perform statistical analysis on this data to take some useful decisions. These choices can display to be of vital importance in numerous fields from industrial employer, Medical, Engineering and Media. Data mining is the exploration and evaluation of massive statistics gadgets, so that it will discover significant sample and policies. The basic concept is to catch out powerful way to mix the PC’s (personal computer) capacity to technique the information along the human eyes potential to encounter styles. The layout and art work effectively with big data unit that is purpose of record data mining. Information discovery from database is the wider process of data mining. Data Mining is the approach of reading facts from specific perspectives and encapsulates the results as helpful facts. It has been defined as "the nontrivial technique of figuring out legitimate, novel, probably beneficial, and ultimately comprehensible patterns in document.
Foreign Bank Subsidiaries’ Default Risk during the Global Crisis; What Factors Help Insulate Affiliates from their Parents?

This paper examines the association between the default risk of foreign bank subsidiaries in developing countries and their parents during the global financial crisis, with the purpose of determining the size and sign of this correlation and, more importantly, understanding what factors can help insulate affiliates from their parents. We find evidence of a significant and robust positive correlation between parent banks’ and foreign subsidiaries’ default risk. This correlation is lower for subsidiaries that have a higher share of retail deposit funding and that are more independently managed from their parents. Host country bank regulations also influence the extent to which shocks to the parents affect the subsidiaries’ default risk. In particular, the correlation between the default risk of subsidiaries and their parents is lower for subsidiaries operating in countries that impose higher capital, reserve, provisioning, and disclosure requirements, and tougher restrictions on bank activities.
Interpretation of sign language into English using NLP techniques

Abstract Sign language is a way of communication for deaf & dumb. Different sign recognition techniques are there which are giving output in the form of word for recognized sign. The proposed method is focusing on interpretation of sign language in proper English sentence. Different NLP techniques are used in addition to sign recognition. Input is given as video of sign language followed by framing & segmentation on video. CamShift algorithm is used for tracking & P2DHMM for hand tracking. Haar Cascade classifier is used for sign identification. After sign recognition, the continuous words for respective sign are given as input to POS tagging module. Word net POS tagger is used which is having its own WordNet dictionary. At last LALR parser is used to frame the sentence. In this way proposed sign language interpreter model gives the output in meaningful English sentence & with a goodaccuracy.
User-Friendly Interface Control Using Segmented Skin Areas

This paper proposes a more natural game interface capable of controlling a game in the way of segmenting hand region robustly, tracing the segmented hand region, and recognizing a user’s gesture. The proposed method is able to detect a user’s eyes, extract reliable skin color samples from the region around the detected eyes, and to create the skin color model most suitable to users. The created skin model is used to segment a user’s hand region robustly. The segmented hand region is then traced so as to recognize a user’s static and dynamic gestures, which are used as a game interface. To evaluate the proposed method, a conventional method and the proposed one were compared. As a result, the proposed method extracted a user’s hand region more robustly than the conventional one and thereby more accurately recognized a user’s gestures. The proposed technique in this paper is expected to be used as a tool to control various game programs to which a similar interface can be applied.
IFNGamma Priming Protects Fetal and Embryonic MSC from NK Cell-Mediated Killing and Improves their Immunosuppressive Properties: Role of Activating and Inhibitory Receptors

The enhancement of Mesenchymal Stem Cells (MSC) immunosuppressing function can favour the engraftment of MSC employed in tissue repair. IFN-γ is a pro-inflammatory cytokine, which induces tolerogenic molecules in bone marrow (BM) MSC. We have investigated the interaction of IFN-γ primed MSC from fetal (FL-MSC) and embryonic (ES-MSC) origin with natural killer (NK) cells. IFN-γ -primed FL-/ES-MSC were less susceptible to NK cell-mediated killing, where a major role was played by the IFN-γ-induced up-regulation of HLA-ABC and HLA-E. Monoclonal antibody-mediated blocking of CD94/NKG2A on NK cells increased killing of IFN-γ-primed MSC, suggesting a role of this NK cell inhibitory receptor in MSC protection. NKG2D ligands (such as MICA), LFA-1 and ICAM1 expressed on MSC were also involved in NK cell-mediated killing of un-primed, but not of IFN-γ-primed, FL-/ES-MSC. Importantly, NK cells from IFN-γ-primed FL-/ES-MSC-NK cell co-cultures displayed a reduced intracellular free calcium increase, pERK activation, degranulation, cytolysis and IFN-γ production upon interaction with the NK sensitive target cell K562 compared to NK cells from un-primed FL/ES-MSC-NK cell co-cultures. Finally, PGE-2, increased during NK/MSC co-cultures, appeared to be a key soluble factor responsible for FL-/ES-MSC-mediated immunosuppressive effect. These results suggest that surface molecules such as MICA, HLA-E and ICAM1 can play a role in recognizing un-primed FL/ES-MSC but not IFN-γ-primed MSC where HLA-I is a key molecule for NK cellmediated recognition. Further, the strong immunosuppressive effect of IFN-γ-primed FL-/ES-MSC on NK cells could be exploited in cellular therapy protocols.
Assessment of GPS/GLONASS RTK Under Various Operational Conditions

The real-time kinematic (RTK) positioning mode uses differential carrier phase ambiguity resolution to achieve sub-decimetre accuracy for numerous applications. In areas of signal shading, GPS measurements alone may not provide the necessary geometry to correctly resolve the ambiguities in a timely manner. The Russian GLONASS system, while currently only partially operational, can provide additional measurements. With a full constellation expected in early 2010, GLONASS is becoming an attractive option for augmenting GPS. However, the frequency division multiple access (FDMA) structure of GLONASS complicates ambiguity resolution. This paper presents a GPS/GLONASS RTK methodology that uses single-differenced pseudorange, phase and Doppler measurements to estimate the position. The GLONASS frequency differences are captured by an additional state. The ambiguities are then resolved in the double-differenced domain. The algorithm was tested for relative vehicle positioning. On the mountain highway, GPS/GLONASS single frequency data provided better horizontal accuracy than GPS-only dual frequency (1 cm vs. 2 cm RMS). In a residential area with overhead foliage, GPS/GLONASS dual frequency data provided sub-decimetre accuracy more often than GPS-only dual frequency (65% vs. 56% of the time). Ambiguity resolution was almost impossible in an urban canyon. GPS/GLONASS single frequency float solutions provided better accuracy and availability than GPS-only dual frequency (10 m RMS and 58% vs. 50 m and 52%).
Further evidence of altered redox status of hyperbilirubinaemic patients: Role of bilirubin in Gilbert syndrome

Bilirubin is regarded as the most powerful endogenous antioxidant substance. It exhibits immunmodulator, inhibitor activities on kinases, yet it is clear that it can be potentially cytotoxic. Gilbert syndrome is characterised by hereditary, chronic, mild unconjugat- ed hyperbilirubinaemia. 12 Gilbert syndrome patients and 15 healthy controls were investigat- ed with special regard to reduction-oxidation status and free radical-antioxidant balance. Sera free SH-group concentration, H-donating ability, reducing power were measured spec- trophotometric methods. Total scavenger capacity, describing free radical-antioxidant balance, was determined by a newly developed chemiluminometric method in sera, plasma and erythrocytes. Patients with Gilbert syndrome showed a significant increase of non-enzymatic antioxidant capacity. Elevated free SH-group concentration, H-donating ability and reducing power were found in mild hyperbilirubinaemia compared with control group patients. On the other hand no significant differences were detected regarding free radical-antioxidant balance in sera, plasma and erythrocytes between the groups. On the basis of these results it can be supposed that elevated bilirubin concentration, via indirect or compensatory way, strengthens non-enzymatic antioxidant capacity, without changes in antioxidant-free radical balance. That is why further investigations are needed to clarify the consequences of elevated bilirubin concentration on cell redox homeostasis
A 52 dB-SFDR 166 MHz sinusoidal signal generator for mixed-signal BIST applications in 28 nm FDSOI technology

This work presents the design, integration and experimental validation of an on-chip sinusoidal signal generator for analog and mixed signal Built-In Self-Test applications. The integrated generator is based on a calibrated harmonic cancellation strategy, previously presented by the authors, that consists in combining five digital square-waves with appropriate phase-shifts and scale weights. The generator employs a digital shift-register to provide a set of phase-shifted digital squarewave signals. These square-wave signals are then scaled and combined using controlled current sources. The proof-of-concept prototype of the sinusoidal signal generator was integrated in STMicroelectronics 28 nm FDSOI technology and characterized in the laboratory to validate the feasibility of the proposal. Obtained results show a performance of 52 dB of SFDR for a generated sinusoidal signal at 166.67 MHz. The generator was tested in an operation frequency range from 1 MHz to 333 MHz.

Can a city communicate? Bradford as a corporate brand

This exploratory research examines how corporate communications can influence stakeholder perceptions to enhance or detract from the city as a brand. It uses the UK city of Bradford as a case study and adopts theoretical concepts of product and corporate branding. Balmer's AC2ID test of corporate identity is applied to identify gaps in the City's official communications strategy, revealing conflicting messages between local government policy and different stakeholder groups. This analysis points to the need for positive visual evidence of change, such as an improved built environment in the city centre. The analysis may have value for policy‐makers in the UK and elsewhere who seek to improve community and stakeholder relationships. This research may also help to promote an honest approach towards branding cities as well as providing the potential for an enhanced brand value.
