Enhancing oral communication through role-playing in EFL primary and secondary school contexts

This study focused on the improvement of oral communication in the classroom. The main concern was to attain better EFL oral communication results through the implementation of classroom role-playing, emphasizing the relevance of certain spoken fluency features. The study was conducted with two A1 groups of eighth and fifth graders aged between 10 and 13 years average at 2 public schools in Bogotá. Data were collected mainly via interviews, videos, a rubric, and teachers’ journals. Results show that role-playing activities allowed students to focus more on realistic oral exchanges and to reach higher levels of motivation in their classroom practices. Additionally, the study proposes that EFL classroom practices should focus on helping students develop fluency from early EFL learning stages. Finally, accuracy and complexity should not be overemphasized as language output, but instead they should be considered EFL learning goals.
Detection Method of Driver Fatigue Based on Blink Duration

This paper uses infrared camera to obtain the image of the driver’s face and locate their eyes with a deformable template in the image. Ituses Kalman filter to track the eyes and obtain the parameters of the blink duration which are used to judge the fatigue of the driver, and researchesthe image processing methods in the algorithm including feature extraction, eyes location and tracking. Experimental results show that blink durationis an effective parameter to judge fatigue.
Running Karp-Rabin Matching and Greedy String Tiling

A system for aligning nucleotide or amino acid biosequences is described. The system, called Neweyes, employs a novel string matching algorithm, Running Karp-Rabin Greedy String Tiling (RKR-GST), which involves tiling one string with matching substrings of a second string. In practice, RKR-GST has a computational complexity that appears close to linear. With RKR-GST, Neweyes is able to detect transposed substrings. Neweyes also supports a form of matching-bygroup that gives the effect of different amino acid mutation matrices. Neweyes can be used in a macro mode (searching a database for a list of biosequences that are similar to a given biosequence) or in a micro mode, where two biosequences are compared and more detailed output formats are available. __________________ 1.

Artist Attribution via Song Lyrics

Song lyrics, separated from the audio signal of their song, still contain a significant amount of information. Mood and meaning can still be conveyed effectively by a pure textual representation. There has even been somewhat successful previous work on genre classification from song lyrics[7]. Building on previous work, we seek to build an artist attribution system for song lyrics. This task is in the same vein as classic author attribution tasks, which often are trained and evaluated on extremely large datasets[8]; providing more data per author than it is possible to get for most songwriters. In order to focus our task, we focus only on rap, as the songwriter and performer are usually the same, and there is a heavy emphasis on distinctive forms of lyricism. We actually enshrine that first assumption in our statement of the classification task: given a textual representation of the lyrics of a rap, return the name of the artist who raps it. This is a limitation we will have to live with for now, there does not exist any large public database that provides ghostwriting information for rappers. Potential use cases for such a classifier would be for detecting misattributed songs in a music library or as part of an auto-tagger in a music management system, along with other uses of author-attribution systems. A lyric-only classifier could also be used in an ensemble method that includes audio-only classifiers. Following previous work[2], we initially attempt to distinguish between 4 prolific rappers (Eminem, Nas, Jay Z, and Nicki Minaj) before expanding the classification task to encompass more artists, testing thoroughly on a 12-artist dataset, and eventually testing on over 300 rappers at once.
Conservation of manuscripts and paintings of South-east Asia

The paintings and manuscripts of South-East and South Asia differ significantly from those found in other parts of the world: birch-bark and palm leaves have been the popular materials used for writing and painting; glue, gum, tamarind seed, and similar aqueous media have been used for the fine line and minute detail. In addition to the specialized care and restoration techniques required by such works, information is provided on the proper display of the paintings. The first chapter provides a brief history of painting in the region; the remaining chapters discuss the conservation of birch-bark, palm leaf, cloth paintings, paper paintings, and thankas. Each chapter gives a detailed account of the composition of the material, its deterioration, conservation techniques, and care and storage in museums.
Mysidacés du plancton marocain

Ce travail fait partie d'une serie d'etudes consacrees au zooplancton recolte dans le secteur atlantique du Maroc (fig. 1) entre les annees 1947 et 1953; les observations portent ici sur les annees 1948 a 1950. Un premier inventaire (1957) des Mysidaces nous a permis d'ajouter six especes aux listes etablies par TATTERSALL (1927) et NOUVEL (1951). Depuis, nous avons determine deux autres formes nouvelles pour le Maroc et reuni un certain nombre de donnees ecologiques qui constituent l'essentiel de la presente publication. Compte tenu des mentions dues a d'autres auteurs, la liste des Mysidaces du Maroc, dans la limite des fonds de mille metres, telle que nous l'avons completee, comprend desormais vingt-cinq especes. Dix-neuf figurent dans notre materiel et vont etre l'objet d'une etude particuliere. Nos recoltes personnelles comptent 6080 specimens dont 5 824 ont pu etre determines et se repartissent numeriquement selon l'ordre de la liste ci-apres. Parmi les 256 autres. trop endommages ou trop jeunes pour permettre une identification exacte, six ont ete rapportes a Leptomysis mediterranea et trois a Boreomysis microps, mais sous reserve, raison pour laquelle ils n'ont pas ete inclus dans cette liste.

Products and practices. Selected concepts from science and technology studies and from social theories of consumption and practice

Design researchers and practitioners are increasingly interested in how designed artefacts shape and are shaped by the contexts in which they are used. Despite a long if selective history of theoretical engagement between design and social science, there has yet to be an effective exchange of ideas on this subject in particular. In this paper, we present a selection of concepts drawn from recent debates in science and technology studies and consumption theory. We introduce notions of acquisition; scripting; appropriation; assembly; normalisation and practice with the aim of initiating an inter-disciplinary conversation about how designed artefacts are configured and appropriated and about how they structure the social practices and situations of which they are a part
Une boite quantique dans un fil photonique : spectroscopie et optomécanique

Dans cette these, nous avons etudie les proprietes optiques de boites quantiques InAs/GaAs contenues dans un fil photonique. Des resultats anterieurs a cette these ont montre que ces fils photoniques permettent d’extraire les photons avec une efficacite tres elevee.Le premier resultat original de ce travail est l’observation de la derive temporelle de la raie d’emission de la photoluminescence d’une boite quantique. Cet effet a ete attribue a la lente modification de la charge de surface du fil due a l’absorption des molecules d’oxygene presentes dans le vide residuel du cryostat. Nous avons montre qu’une fine couche de Si3N4 permettait de supprimer cette derive. La derive temporelle pouvant etre differente pour differentes boites quantiques, nous avons pu tirer partie de cet effet pour mettre en resonance deux boites quantiques contenues dans le meme fil.Le deuxieme resultat original est la mise en evidence de la modification de l’energie d’emission d’une boite quantique soumise a une contrainte mecanique induite par la vibration du fil. Nous avons observe que le spectre de la raie d’emission d’une boite quantique s’elargit considerablement lorsque le fil est mecaniquement excite a sa frequence de resonance. A l’aide d’une illumination stroboscopique synchronisee avec l’excitation mecanique, nous avons pu reconstruire l’evolution du spectre d’une boite quantique au cours d’une periode de la vibration mecanique. L’amplitude de l’oscillation spectrale de la raie de luminescence depend de la position de la boite dans le fil a cause d’un tres fort gradient de contrainte. En utilisant deux modes d’oscillation mecanique de polarisations lineaires et orthogonales, nous pouvons extraire une cartographie complete de la position des boites quantiques a l’interieur du fil. Enfin, grâce a ce gradient, on peut, dans certains cas, trouver une position du fil pour laquelle deux boites quantiques peuvent etre amenees en resonance.
Protein Sculptures: Life's Building Blocks Inspire Art

Abstract The author takes a literal look at the foundation of our physical existence by creating sculptures of proteins, the universal parts of the machinery of life. For him, it is less important to copy a molecule accurately in all its details than to find a guiding principle and follow it to see whether it yields artistically interesting results. The main idea underlying these sculptures is the analogy between the technique of mitered cuts and protein folding. The sculptures offer a sensual experience of a world that is usually accessible only through the intellect.
Improving Makers’ Remix Contribution Behavior in the Open Innovation Communities——An Example of Thingiverse

Using existing innovations as raw materials or inspiration to promote further innovation is becoming a new way of knowledge reuse and contribution in open innovation community (OIC). Study on makers’ remix contribution behavior in the open innovation communities will help to promote the development of community innovation based on remix. Based on the theories of social capital, pro-social behavior and psychological ownership, this paper studies how social network relationship, norm of reciprocity, self-rated expertise, peer recognization about remix and psychological ownership influence makers’ remix contribution behavior in OIC. We conduct a negative binominal regression by collecting a large-scale data set mining from Thingiverse, the typical open innovation community. Social network relationship, norm of reciprocity, peer recognization about remix and psychological ownership have a significant positive impact on makers’ remix contribution behavior, while the positive influence of self-rated expertise on remix contribution behavior exists only among novice and intermediate makers. 开放式创新社区中提升创客混音贡献行为——以Thingiverse为例 冯悦 1,a, 马巧鸽 1,b, 任南 1,2,c,* 1江苏科技大学经济管理学院,镇江,江苏,中国 2江苏科技大学服务制造模式与信息化研究中心,镇江,江苏,中国 a843092849@qq.com, b1990253622@qq.com, c444755378@qq.com *通讯作者 关键词:开放式创新社区; 创客; 混音; 知识重用 中文摘要. 利用现有创新作为原材料或灵感来促进进一步创新的混音正成为开放式创新社区 (OIC)中一种新兴的创客知识重用和贡献方式,研究OIC中的创客混音贡献行为有助于促进 社区基于混音加强创新的发展。 基于社会资本、亲社会行为以及心理所有权理论,结合典型 开放式创新社区——Thingiverse社区,通过网络数据挖掘,运用负二项回归,从社会网络关 系、互惠规范、专业知识水平、混音的同行认可和心理所有权五个维度研究OIC中创客混音 贡献行为。 社会网络关系、互惠规范、混音的同行认可以及心理所有权对创客混音贡献行为 有显著正向影响,专业知识水平对混音贡献行为的积极影响只存在于初级和中级知识水平的 创客中。 224 Copyright © 2019, the Authors.

Looking for Africa in Carl Einstein's Negerplastik

In 1914, two men strove to publish the first theoretical treatise on African art composed in a European language. The Latvian painter Voldemārs Matvejs and the German author Carl Einstein worked virtually simultaneously and without knowledge of one another. Matvejs died precipitously in May, delaying publication of his manuscript, Iskusstvo Negrov (“Negro Art”) until 1919. During his lifetime, Latvia was part of the Russian Empire and Matvejs wrote in Russian under the pseudonym of “Vladimir Markov. ” When published, after the Revolution, his text exercised a formative impact on the Soviet avant-garde, for instance, on Malevich, Tatlin, and Rodchenko, before the Stalinist art establishment consigned it to oblivion in the 1930s. Einstein’s book Negerplastik (“Negro sculpture”) appeared in 1915 with notable success, but then also gradually disappeared from view.1 Since 1961, the text has garnered increasing attention thanks to the rising profile of Einstein himself. For both men, the claim to be the “discoverer of African art”2 has helped shaped their image as culture heroes suitable for canonization in the twenty-first century. But what role was there for Africa in theories of African art? Simon Gikandi warns us: “Much has been written on Picasso and primitivism but little on his specific engagement with Africa” (2006:33). 3 By so doing, he argues that scholars replicate Picasso’s own strategies in separating works of art from the people and societies that produced them and perhaps for the same reason: “to minimise . the constitutive role of Africa in the making of modernism” (ibid., p. 34). The questions asked of Picasso need to be posed for the larger community of European modernists fascinated by art objects from other parts of the world. This essay takes up Gikandi’s challenge to query what the critic Carl Einstein believed about Africans and what his sources were.4 The FirsT LiFe oF NegerpLasTik: The phoTographs5 “Another hole in the classical canon of beauty. ”—Hermann Hesse
The Impact of Insurance on HIV Testing

This paper investigates the effects of health insurance on HIV testing rates among the US general population using nationally representative data from the Behavioral Risk Factor Surveillance Survey (BRFSS) for the years 1993 to 2003. We estimate recursive bivariate probit models with insurance coverage and HIV testing as the dependent variables. We use changes in Medicaid eligibility and distribution of firm size over time within a state as instruments for insurance coverage. The results suggest that (1) insurance coverage increases HIV testing rates, (2) insurance coverage increases HIV testing rates more among the high-risk population, and (3) the effects of insurance coverage on HIV testing for high-risk populations increased over time.
Remedial Education and Student Achievement: A Regression-Discontinuity Analysis

As standards and accountability have become increasingly prominent features of the educational landscape, educators have relied more on remedial programs such as summer school and grade retention to help low-achieving students meet minimum academic standards. Yet the evidence on the effectiveness of such programs is mixed, and prior research suffers from selection bias. However, recent school reform efforts in Chicago provide an opportunity to examine the causal impact of these remedial education programs. In 1996, the Chicago Public Schools instituted an accountability policy that tied summer school and promotional decisions to performance on standardized tests, which resulted in a highly nonlinear relationship between current achievement and the probability of attending summer school or being retained. Using a regression discontinuity design, we find that the net effect of these programs was to substantially increase academic achievement among third-graders, but not sixth-graders. In addition, contrary to conventional wisdom and prior research, we find that retention increases achievement for third-grade students and has little effect on math achievement for sixth-grade students.
Understanding the Paradoxes of Multilevel Governing: Climate Change Policy in the European Union

The European Union (EU) has sought to lead the world in the adoption of ambitious climate change mitigation targets and policies. In an attempt to characterize and broadly explain the resulting pattern of EU climate governance, scholars have employed the term “multi-level reinforcement. ” This term does help to account for the paradoxical situation whereby the EU seeks to lead by example but is itself a relatively leaderless system of governance. Drawing on a much fuller empirical account of the evolution of EU climate governance, this article finds that the term captures some but not all aspects of the EU's approach. It identifies four other paradoxical features of the EU's approach and assesses the extent to which they exhibit “multi-level reinforcement. ” It concludes by looking forward and examining the extent to which all five features are expected to enable and/or constrain the EU's ability to maintain a leading position in climate governance.
Financial Activism and Global Climate Change: The Rise of Investor-Driven Governance Networks

This article examines the nexus between financial activism and global environmental governance, analyzing the emergence of what we call investor-driven governance networks (IGNs). Our paper seeks to probe the significance of IGNs as a particular manifestation of responsible investor activism and more generally as a financial instrument of environmental governance and sustain-ability. We argue that IGNs, many of which are concerned with climate change governance, have become important actors in the global economy and deserve more analysis by scholars concerned with new forms of authority in global environmental politics. As an example of emerging transnational private governance, IGNs utilize the power of the financial sector to shape the discourse on climate change within the business community and to link the long-term viability of environmental sustainability to the core strategic interests of corporations and investors.
Fiscal Impacts of Charter Schools: Lessons from New York

This brief argues that charter school programs can have direct fiscal impacts on school districts for two reasons. First, operating two systems of public schools under separate governance arrangements can create excess costs. Second, charter school financing policies can distribute resources to or away from districts. Using the city school districts of Albany and Buffalo in New York, we demonstrate how fiscal impacts on local school districts can be estimated. We find that charter schools have had fiscal impacts on these two school districts. Finally, we argue that charter schools policies should seek to minimize any avoidable excess costs created by charter schools and ensure that the burden of any unavoidable excess costs is equitably distributed across traditional public schools, charter schools, and the state. We offer concrete policy recommendations that may help to achieve these objectives.
Intranational Home Bias in Trade

A number of recent studies have found intranational trade to be excessive compared to international trade, based on a gravity specification. The preferred explanation for this finding has been the presence of formal and informal trade barriers, with associated welfare consequences. If such barriers were indeed the sole culprit, home bias should not exist on the subnational level. We find, however, that home bias is present within U.S. states, suggesting the presence of other causes of excessive home trade.
Bayesian Estimation and Smoothing of the Baseline Hazard in Discrete Time Duration Models

This paper proposes a Bayesian approach for estimating and smoothing the baseline hazard in a discrete time hazard model. The hazard model is specified as a multiperiod probit model and estimated using a Gibbs sampler with data augmentation. The baseline hazard specification is smoothed using the smoothness priors introduced by Shiller (1973). The methods proposed in this paper are then used to study the effect of Canadian Unemployment Insurance eligibility rules on employment durations from New Brunswick, Canada.
Determinants of Knowledge Flows and Their Effect on Innovation

Knowledge flows within and across countries may have important consequences for both productivity and innovation. We use data on 1.5 million patents and 4.5 million citations to estimate knowledge flows at the frontier of technology across 147 subnational regions during 19751996 within the frame of a gravity-like equation. We estimate that only 20 of average knowledge is learned outside the average region of origin, and only 9 is learned outside the country of origin. However, knowledge in the computer sector flows substantially farther, as does knowledge generated by technological leaders. In comparison with trade flows, we see that knowledge flows reach much farther. External accessible R&D gained through these flows has a strong positive effect on innovative activity for a panel of 113 European and North American regions over 22 years.
Heuristic, Methodology or Logic of Discovery? Lakatos on Patterns of Thinking

Heuristic is a central concept of Lakatos' philosophy both in his early works and in his later work, the methodology of scientific research programs (MSRP). The term itself, however, went through significant change of meaning. In this paper I study this change and the metaphysical commitments behind it. In order to do so, I turn to his mathematical heuristic elaborated in Proofs and Refutations. I aim to show the dialogical character of mathematical knowledge in his account, which can open a door to hermeneutic studies of mathematical practice.
Franchising in Frontier Markets: What's Working, What's Not, and Why

employment Program for Organized Transport) is now the largest taxi operator in the capital city of India’s “Silicon Valley,” having grown organically from 18 cars in 1999 to the more than 300 operating today, 24/7. SPOT was started to promote employment, enable asset ownership, and build credit history among low-income households. Unlike other taxi operators in the city, SPOT’s fleet is driven by owners, who operate franchise businesses linked by a common brand, a computerized radio dispatch system, and standards for service, processes, and values. Typical of franchise businesses the world over, SPOT combines the management and financial strengths of an established corporate entity with the entrepreneurial vigor and aligned incentives that come with business ownership. SPOT drivers purchase the cars on installment over a threeto four-year period, with vehicle leases arranged on favorable terms by the franchisor. In addition to arranging financing, SPOT offers an established network of pooled customer demand, fleet-management services, and a dispatch center that channels customer
When Distance Disappears: Inventors, Education, and the Locus of Knowledge Spillovers

Abstract This paper discusses the role of education in shaping the geographical breadth of knowledge spillovers. Data pertaining to 6,051 European inventions reveal that inventors with a high level of education, such as a university or doctoral degree, rely more on external spillovers regardless of the geographical location of their sources. Controlling for this effect, they also access geographically wider knowledge spillovers. This result holds after controlling for alternative explanations, such as the inventors' network and the site where the research is performed. By contributing to individual openness, education thus provides a means to break through geographical barriers to attain knowledge diffusion.
Presupposition and Anaphora: Remarks on the Formulation of the Projection Problem

Writers on presupposition, and on the projection problem of determining the presuppositions of compound sentences from their component clauses, traditionally assign presuppositions to each clause in isolation. I argue that many presuppositional elements are anaphoric to previous discourse or contextual elements. In compound sentences, these can be other clauses of the sentence. We thus need a theory of presuppositional anaphora, analogous to the corresponding pronominal theory.
