A SOCIOCOGNITIVE-TRANSFORMATIVE APPROACH TO TEACHING WRITING

Abstract. This article reports some of the compelling concerns in using various approaches to teaching writing. On this note, this paper provides an alternative teaching framework for the teaching of ESL writing to address these concerns. This sociocognitive-transformative framework incorporates the cognitive, social, cultural, and transformative components of learning. Specifically, the discussion covers three sections that shed light on the theoretical underpinning, the design, and procedure on how the proposed approach can be realized in ESL writing classrooms. It is also hoped that through this approach, the teaching and learning of writing would lead to producing 21st century learners capable of surviving this highly globalized and knowledge-based society

Enseñanza de la post-escritura centrada en la forma en los procesos de las clases de composición escrita orientadas hacia el género: Efectos en la precisión de la escritura de los estudiantes de segunda lengua

Recent findings have provided growing evidence in support of process-genre-oriented writing pedagogy. However, these types of approaches tended to place form-focused instruction (FFI) in the background, particularly the explicit teaching of grammar (i.e., isolated FFI). As such, limited improvement in writing accuracy was reported by recent studies. It is, therefore, important to look into how isolated FFI might further improve this aspect of writing within process-genre-oriented writing classrooms. Thus, the current study investigates the effects of post-writing isolated FFI (post-FFI) on second language (L2) writing accuracy within this writing environment. Using mixed methods quasi-experimental design, the findings show that post-FFI benefits students as it improved their overall writing accuracy, particularly errors that impede meaning (levels 2 and 3 errors). This improvement was attributed to noticing, contextualised learning of forms, and students’ psycholinguistic readiness as supported by students’ qualitative responses. Nonetheless, some challenges were also reported by students regarding the intervention. Implications for L2 writing pedagogy and future research are discussed.Recientes hallazgos han proporcionado una creciente evidencia en apoyo de la pedagogía de la escritura procesual orientada al género. Sin embargo, estos tipos de enfoques tienden a colocar la instrucción centrada en la forma (FFI) en un segundo plano, en particular la enseñanza explícita de la gramática (es decir, FFI aislado). Por ello, los estudios recientes informan de una mejora limitada en la precisión de la escritura. Por lo tanto, es importante investigar cómo la FFI aislada podría mejorar aún más este aspecto de la escritura dentro de las aulas de escritura como proceso orientadas al género. El presente estudio investiga los efectos del FFI aislado en la post-escritura (post-FFI) en la precisión de la escritura de la segunda lengua (L2) dentro de este entorno de escritura. Utilizando un diseño cuasi-experimental de métodos mixtos, los resultados muestran que el post-FFI beneficia a los estudiantes, ya que mejora su precisión general en la escritura, particularmente los errores que impiden el significado (errores de nivel 2 y 3). Esta mejora se atribuyó a la atención, al aprendizaje contextualizado de las formas y a la preparación psicolingüística de los estudiantes, tal y como se desprende de sus respuestas cualitativas.&nbsp

The Long-term Diffusion of Digital Platforms — An Agent-based Model

In recent years, many industries have experienced the rise of digital platforms (e.g., eBay, Uber, or Takeaway.com). A common characteristic of these concepts is that they focus on fragmented markets populated by many small firms, which often show a high fluctuation. However, established diffusion models based on Bass (1969) do not account for fluctuation in the market potential, although the exit of adopters and the entry of new firms could change the diffusion curve significantly. Thus, we propose an extension of the Bass Model to account for the exit and entry of (potential) adopters and empirically test this framework in a real-world setting. Using two decades of adopter data of leading digital platforms and information on the complete market potential, we employ agent-based models to analyze the effects of fluctuation on the platform diffusion. Initial results confirm the existence of high fluctuation and indicate relevant impacts on the diffusion curve

ACCURACY ORDER OF THE GRAMMATICAL MORPHEMES IN THE ORAL PRODUCTION OF PRESCHOOL PUPILS

Abstract. There are numerous studies concerning the order of acquisition of grammatical morphemes; however, no paper to the knowledge of the authors has explored the accuracy order and acquisition of grammatical morphemes of Filipino children. The present study investigated the accuracy order of 14 English grammatical morphemes of Filipino preschool pupils. Specifically, this paper sought to determine the grammatical morphemes which have the highest and lowest accuracy level by Filipino preschool pupils. It also attempted to identify whether there is a relationship between the order of grammatical morpheme acquisition of Filipino preschool pupils compared to the order of grammatical morpheme wherein English is the first language and English is the second language. The participants involved in this study were 18 preschool pupils whose age ranges from three to five years old. These participants were divided into two clusters based on their linguistic and geographical background.   The findings revealed that plurality and progressive verbs posted the highest accuracy level while prepositions and past irregular verbs had the lowest level of accuracy. As regards the relationship between the order of acquisition, the results revealed that the present study posted a different order compared to Dulay and Burt’s (1973) and Brown’s (1973) studies through Kendall coefficient of concordance and Spearman Rank Order Correlation. Keywords: Accuracy order, L2 acquisition, order of acquisition, grammatical morphemes KEAKURATAN URUTAN MORFEM TATA BAHASA DALAM PRODUKSI LISAN SISWA PRA-SEKOLAHAbstrak: Ada banyak kajian mengenai urutan pemerolehan morfem-morfem tata bahasa, akan tetapi sepengetahuan penulis tidak ada makalah yang telah menggali keakuratan urutan dan pemerolehan morfem tata bahasa diantara anak-anak Filipina. Kajian ini menyelidiki keakuratan urutan dari empat belas morfem tata bahasa Inggris diantara siswa pra-sekolah Filipina. Khususnya, makalah ini berusaha untuk menentukan morfem-morfem tata bahasa yang memiliki tingkat keakuratan tertinggi dan terendah diantara siswa pra-sekolah Filipina. Kajian ini juga berusaha untuk melihat apakah ada hubungan antara urutan pemerolehan morfem tata bahasa para siswa pra-sekolah Filipina dengan urutan morfem tata bahasa dimana Inggris sebagai bahasa pertama dan kedua. Para peserta yang terlibat dalam kajian ini adalah 18 siswa pra-sekolah yang berumur antara tiga sampai lima tahun. Para peserta ini dibagi ke dalam dua kelompok berdasarkan latar belakang bahasa dan geografisnya. Temuan-temuan menunjukkan bahwa kata-kata kerja jamak dan progresif (sedang berlangsung) memiliki keakuratan paling tinggi, sementara kata depan dan kata-kata kerja tidak beraturan lampau memiliki keakuratan yang paling rendah. Mengenai hubungan antara urutan pemerolehan, hasilnya mengungkapkan bahwa kajian ini menunjukkan urutan yang berbeda dibanding dengan hasil kajian Dulay dan Burt (1973) serta Brown (1973) melalui koefisien keselaran (coefficient of concordance) Kendall dan Korelasi Urutan Ranking (Rank Order Correlation) Spearman. Katakunci: Keakuratan urutan, pemerolehan bahasa kedua, urutan pemerolehan, morfem tata bahas

Input Specificity and the Propagation of Idiosyncratic Shocks in Production Networks

This article examines whether firm-level idiosyncratic shocks propagate in production networks. We identify idiosyncratic shocks with the occurrence of natural disasters. We find that affected suppliers impose substantial output losses on their customers, especially when they produce specific inputs. These output losses translate into significant market value losses, and they spill over to other suppliers. Our point estimates are economically large, suggesting that input specificity is an important determinant of the propagation of idiosyncratic shocks in the economy

Investigation of laser induced phosphorescence and fluorescence of acetone at low pressure for molecular tagging velocimetry in gas microflows

This paper was presented at the 4th Micro and Nano Flows Conference (MNF2014), which was held at University College, London, UK. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute, ASME Press, LCN London Centre for Nanotechnology, UCL University College London, UCL Engineering, the International NanoScience Community, www.nanopaprika.eu.Laser-induced fluorescence and phosphorescence properties of gaseous acetone in argon are measured and analyzed in a pressure ranging from 10(5) to 10(2) Pa, with the aim of analyzing by molecular tagging velocimetry gas microflows in rarefied regimes which requires operation at low pressure. Acetone is excited at a wavelength of 266 nm and immediately emits short lifetime fluorescence rapidly followed by long lifetime phosphorescence. At atmospheric pressure, the early phosphorescence intensity is more than 600 times lower than the fluorescence one. The phosphorescence signal is rapidly decreasing with time, closely following a power law. Both fluorescence and phosphorescence signals are decreasing with pressure. The systematic analysis of fluorescence and phosphorescence of acetone molecules shows that although the signal is dramatically reduced at low pressure, the on-chip integration technique and the optimization of the acquisition parameters provide an exploitable signal for molecular tagging velocimetry in rarefied microflows, in a Knudsen number range corresponding to the early slip flow regime

Genetic Changes Over Breeding Generations of \u3cem\u3eFestulolium\u3c/em\u3e

Festulolium hybrids are a valuable breeding source for tolerance to abiotic stress and to make grass more persistent under drought and in cold environments. In 2004, the EU Commission enlarged the definition of Festulolium which may now include all hybrids between Lolium sp. and Festuca sp. and not only those between L. multiflorum and F. pratensis. We here report allele frequencies at two unlinked PCR-based marker loci in populations derived from tetraploid (2n=4x=28) L. multiflorum x F. glaucescens hybrids where breeding history enables us to test the effects of selection vs that of genetic drift

Sur les aspects computationnels du vote par approbation

The subject of this thesis is the study of computational aspects of approval voting. Most of the works are theoretical results about computational issues raised by approval voting, in many different settings. However, I also study some questions that are more related to classical choice theory, and some problems are investigated through experimental analysis.Firstly, I study a general family of rules for approval voting in the context of committee elections and multiple referenda. Secondly, I focus on a more general setting, approval voting in combinatorial domains, based on conditional preferences. Finally, I consider approval voting in the context of incomplete preferences, to study the possible and necessary winner problems.L'objet de cette thèse est l'étude des aspects algorithmiques du vote par approbation. Il s'agit principalement d'une étude théorique des enjeux computationnels soulevés par le vote par approbation dans des contextes de décisions variés. Cependant, j'étudie aussi des questions plus proches de la théorie classique du choix social et je conduis de brèves études expérimentales.Dans un premier temps, l'étude se porte sur une famille générale de règles de vote pour les élections de comités et les référendums multiples à l'aide du vote par approbation. Dans un second temps, je porte mon attention sur un contexte plus général, le vote par approbation sur domaines combinatoires en se basant sur des préférences conditionnelles. Finalement, je me place dans le cadre du vote avec préférences incomplètes pour étudier les problèmes de vainqueurs possibles et nécessaires dans le vote par approbation
