Dynamic Alpha: A Spectral Decomposition of Investment Performance Across Time Horizons
Authors: Chaudhuri Shomesh E. , Lo Andrew W.
Published: October 2018

The value added by an active investor is traditionally measured using alpha, tracking error, and the information ratio. However, these measures do not characterize the dynamic component of investor activity, nor do they consider the time horizons over which weights are changed. In this paper, we propose a technique to measure the value of active investment that captures both the static and dynamic contributions of an investment process. This dynamic alpha is based on the decomposition of a portfolio’s expected return into its frequency components using spectral analysis. The result is a static component that measures the portion of a portfolio’s expected return resulting from passive investments and security selection and a dynamic component that captures the manager’s timing ability across a range of time horizons. Our framework can be universally applied to any portfolio and is a useful method for comparing the forecast power of different investment processes. Several analytical and empirical examples are provided to illustrate the practical relevance of this decomposition.

¿El ecosistema o los ecosistemas? Primeras evidencias de un ejercicio de tipologías sobre ciudades de la Provincia de Santa Fe (Argentina)
Authors: Ibarra García Sabrina , Federico Juan , Ortíz Mariana , Kantis Hugo
Published: October 2018

El concepto de Ecosistema Emprendedor (en adelante EE) ha ganado importancia en los últimos años como referencia para describir las condiciones y el marco institucional que promueven la creación de empresas dinámicas en un territorio específico (Brown y Mason, 2017; Isenberg, 2011; Kantis, 2017; Stam y Spigel, 2016). Recientes análisis bibliométricos dan cuenta de que el número de referencias al concepto de EE ha venido creciendo de manera significativa a partir de 2013 (Cavallo, Ghezzi y Balocco, 2018; Borissenko y Boschma, 2017).
Visible + Near Infrared Spectroscopy as taxonomic tool for identifying birch species
Authors: Tigabu Mulualem , Farhadi Mostafa , Stener Lars-Göran , Odén Per
Published: October 2018

The genus L. is composed of several species, which are difficult to distinguish in the field on the basis of morphological traits. The aim of this study was to evaluate the taxonomic importance of using visible + near infrared (Vis + NIR) spectra of single seeds for differentiating Roth and Ehrh. Seeds from several families (controlled crossings of known parent trees) of each species were used and Vis + NIR reflectance spectra were obtained from single seeds. Multivariate discriminant models were developed by Orthogonal Projections to Latent Structures â Discriminant Analysis (OPLS-DA). The OPLS-DA model fitted on Vis + NIR spectra recognized with 100% classification accuracy while the prediction accuracy of class membership for was 99%. However, the discriminant models fitted on NIR spectra alone resulted in 100% classification accuracies for both species. Absorption bands accounted for distinguishing between birch species were attributed to differences in color and chemical composition, presumably polysaccharides, proteins and fatty acids, of the seeds. In conclusion, the results demonstrate the feasibility of NIR spectroscopy as taxonomic tool for classification of species that have morphological resemblance.BetulaBetula pendulaBetula pubescensB. pubescensB. pendula
Resolving the Terminological Mishmash in Teaching Link Words in EFL Writing
Authors: Yousefpoori-Naeim Mehrdad , Zhang Lawrence Jun , Baleghizadeh Sasan
Published: October 2018

One of the characteristics of good writing is appropriate use of cohesive devices, which many learners often find difficult to do. Although there is a substantial body of research on cohesion in writing, little has been documented on how to teach it to EFL students. The present study was an attempt to address this under-researched issue by taking a terminological approach, as the diverse and vague terminology used to describe link words has been found to be more of a hindrance than a facilitator in the teaching/learning process. A total of 16 cohesion-related terms were surveyed to find out about the quality and quantity of their use in a self-built corpus of 14 grammar books of different levels. Furthermore, a test was run to measure students’ familiarity with these terms, and field-notes were taken while scoring the students’ papers in their presence. The findings, in addition to giving insights into the usage points regarding each of the 16 terms, led to drawing a terminological network, which, if used consistently, could help in teaching and learning to use cohesion effectively.

Published: October 2018

Background

The Mentha rotundifolia L. (Lamiaceae family), is a medicinal herb used since the ancient times as an antiseptic, analgesic and anti-inflammatory agent. In the present work, metabolomic profiling of two Mentha rotundifolia L. ecotypes leaf tissues spontaneously growing in the North of Tunisia was achieved.

Methods

Phenolic contents (TPC, TFC and TTC) were assessed using colorimetric methods. Metabolomic profiling of leaf tissues extracts was assessed based on Gas Chromatography-Mass Spectrometry (GC/MS) analysis. The antioxidant ability of M. rotundifolia extracts was achieved based on two test systems namely DPPH and FRAP assays. Antimicrobial activity against a set of Gram negative and Gram positive bacteria was estimated by measuring ID, MIC and MBC values.

Results

Fifty metabolites were identified as belonging mainly to phenolics, fatty acids, terpenes, steroids and aldehydes classes with qualitative and quantitative variability. Most of the identified compounds are reputed bioactive with potent antioxidant, antimicrobial and anti-inflammatory among others effects. To confirm these findings common in vitro biological activities were achieved. The investigated extracts showed significant antioxidant abilities based on both 1,1-diphenyl-2-picrylhydrazyl (DPPH) and Ferric reducing antioxidant potential (FRAP) assays. Furthermore, the extracts revealed promising antimicrobial ability against tested Gram+ and Gram- bacterial strains (ID: 12.5–14.5 mm, MIC: 3.125–25 (µg/mL), MBC: 6.25–100 (µg/mL)).

Conclusions

Based on our findings Mentha rotundifolia L. leaves extracts present a potential source of natural antioxidants and diverse bioactive compounds which could be used in green pharmacy, food preservation, alternative medicine and natural therapies.
Grammaticalization of nouns meaning “head” into reflexive markers: A cross-linguistic study
Authors: Evseeva Natalia , Salaberri Iker
Published: October 2018

Studies on the grammaticalization of body-part nouns into reflexives have often formulated cross-linguistic generalizations, but have mostly failed to provide detailed analyses of similar developments attested in unrelated languages. As a consequence, valuable insights have sometimes been overlooked. The purpose of this paper is twofold: on the one hand, it identifies a higher number of languages using “head”-reflexives than previous accounts. On the other hand, its purpose is to analyze the diachronic evolution of nouns denoting “head” into reflexive markers in three unrelated language groups (Basque, Berber and Kartvelian) and to show how “head”-reflexives synchronically and diachronically interact with secondary reflexivization strategies, such as detransitivization. The results suggest that the areal factor has a considerable impact on the emergence of “head”-reflexives; they also show that none of the languages analyzed reflects all grammaticalization stages put forward in the literature. Accordingly, it is argued that the grammaticalization stages are optional, and that the correlation between formal and semantic change is not obligatory.

Choe, KH, Coburn, JW, Costa, PB, and Pamukoff, DN. Hip and knee kinetics during a back-squat and deadlift. J Strength Cond Res 35(5): 1364–1371, 2021—The back-squat and deadlift are performed to improve hip and knee extensor function. The purpose of this study was to compare lower extremity joint kinetics (peak net joint moments [NJMs] and positive joint work [PJW]) between the back-squat and deadlift. Twenty-eight resistance-trained subjects (17 men: 23.7 ± 4.3 years, 1.76 ± 0.09 m, 78.11 ± 10.91 kg; 11 women: 23.0 ± 1.9 years, 1.66 ± 0.06 m, 65.36 ± 7.84 kg) were recruited. One repetition maximum (1RM) testing and biomechanical analyses occurred on separate days. Three-dimensional biomechanics of the back-squat and deadlift were recorded at 70 and 85% 1RM for each exercise. The deadlift demonstrated larger hip extensor NJM than the back-squat {3.59 (95% confidence interval [CI]: 3.30–3.88) vs. 2.98 (95% CI: 2.72–3.23) Nm·kg−1, d = 0.81, p < 0.001}. However, the back-squat had a larger knee extensor NJM compared with the deadlift (2.14 [95% CI: 1.88–2.40] vs. 1.18 [95% CI: 0.99–1.37] Nm·kg−1, d = 1.44 p < 0.001). More knee PJW was performed during the back-squat compared with the deadlift (1.85 [95% CI: 1.60–2.09] vs. 0.46 [95% CI: 0.35–0.58] J·kg−1, d = 2.10, p < 0.001). However, there was more hip PJW during the deadlift compared with the back-squat (3.22 [95% CI: 2.97–3.47] vs. 2.37 [95% CI: 2.21–2.54] J·kg−1, d = 1.30, p < 0.001). Larger hip extensor NJM and PJW during the deadlift suggest that individuals targeting their hip extensors may yield greater benefit from the deadlift compared with the back-squat. However, larger knee extensor NJM and PJW during the back-squat suggest that individuals targeting their knee extensor muscles may benefit from incorporating the back-squat compared with the deadlift.

Authors: Pozuelo-Carrascosa Diana P. , Cavero-Redondo Iván , Herráiz-Adillo Ángel , Díez-Fernández Ana , Sánchez-López Mairena , Martínez-Vizcaíno Vicente
Published: October 2018

CONTEXT:

The effects of school-based physical activity (PA) programs on different cardiometabolic risk factors and the most appropriate features of PA programs to achieve maximum effectiveness are unclear.

OBJECTIVE:

To provide a comprehensive synthesis of the effectiveness of school-based PA interventions on cardiometabolic risk factors in children.

DATA SOURCES:

We identified studies from database inception to February 22, 2018.

STUDY SELECTION:

We selected studies that were focused on examining the effect of school-based PA interventions on cardiometabolic risk factors in children.

DATA EXTRACTION:

Random-effects models were used to calculate the pooled effect size (ES) for the included cardiometabolic risk factors (waist circumference [WC], triglycerides, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, systolic blood pressure and diastolic blood pressure (DBP), and fasting insulin and glucose).

RESULTS:

Nineteen randomized controlled trials (which included 11 988 children aged 3–12 years) were included in the meta-analysis. School-based PA programs were associated with a significant small improvement in WC (ES = −0.14; 95% confidence interval [CI]: −0.22 to −0.07; P < .001), DBP (ES = −0.21; 95% CI: −0.42 to −0.01; P = .040), and fasting insulin (ES = −0.12; 95% CI: −0.20 to −0.04; P = .003).

LIMITATIONS:

Authors of few studies described the implementation conditions of their interventions in detail, and compliance rates were lacking in most studies. In addition, results by sex were provided in a small number of studies.

CONCLUSIONS:

School-based PA interventions improve some cardiometabolic risk factors in children, such as WC, DBP, and fasting insulin.

With the aim to establish the hematological analyte reference limits of clinically healthy adult goats of dairy producing breeds, subjected to the handling and characteristics of intensive production systems in the Mexican Plateau, the blood samples of 2-year old and older goats at different production stages were collected and analyzed. Reference limits (interval in brackets) for hematocrit (0.22 - 0.36 L/L), erythrocyte count (9.07 - 18.47 ×1012/L), mean cell volume (MCV) (14.44 - 27.91 fL), platelets (229 - 3163 ×109/L), total solids (65.64 - 84.64 g/L), fibrinogen (0 - 6 g/L), leukocyte count (3.75 - 11.47 ×109/L), segmented neutrophils (0.95 - 4.98 ×109/L), band neutrophils (0 - 0.16 ×109/L), lymphocytes (1.76 - 6.44 ×109/L), monocytes (0 - 0.65 ×109/L), eosinophils (0 - 1.36 ×109/L) and basophils (0 - 0.37 ×109/L) were obtained. These values were compared with similar study results. Differences were found mainly in the values for hematocrit, erythrocytes, MCV, platelets, total leukocytes, and lymphocytes; this is due to environmental and feeding differences between the studies.
Influencia del hidrolizado de proteínas en el comportamiento bioproductivo en gallinas de la línea L1 White Leghorn
Authors: Colas Manuel , Pérez Edmundo Oliver , Támbara Yanet
Published: October 2018

The objective of this study was to evaluate the influence of protein hydrolysates (PH), as a nutritional supplement, in the bioproduction performance of White Leghorn hens. Thirty-nine-week old light line hens were assessed during six weeks. Two treatments (T) were designed involving 320 hens each (three replications of 40 hens each). In T1, each bird received 2 ml of PH daily; the birds in T2 were not offered the product. The following variables were controlled: bioproduction (total egg production, egg-laying percentage, total feed intake, mass conversion, viability, and caused mortality); incubation indicators (eggs to plant, incubation percentage, hatchability, and top quality chicks) and; quality (feed intake by top quality chicks, and top quality chicks per hen). The hens that received the PH showed significant differences in the laying, incubation, and hatchability percentage, as well as mass conversion, and the egg to plant ratio. They showed better performance in quality indicators. It is concluded that the use of PH in light line hens improves their bioproduction performance, as well as the indicators of to incubation, egg to plant ratio, and hatchability; its use also reduces by approximately 100 grams the necessary food intake to obtain top quality chicks.

Authors: Zamudio Juan Felipe , Landines Miguel Ángel
Published: October 2018

The effect of food restriction and refeeding on some physiological variables in yamú (Brycon amazonicus) was evaluated using 1115 juveniles (initial weight 217.75 g ± 14.74 g), distributed in three ponds. The groups were randomly assigned one of the following treatments: 1) Control (C), fed every day; 2) Moderate restriction (MR), restriction during two days and refeeding during three; and 3) Severe restriction (SR), total restriction during five weeks and refeeding from week 6 to 12. Blood samples from 7 animals from each treatment were taken on days 1, 35, 42, 56, 70, and 84 to determine hematocrit, proteins, glucose, lactate, triglycerides, cholesterol, cortisol, T3, and insulin. The animals were sacrificed and their livers removed to calculate the hepatic glycogen. The experimental design used was a fixed effects mixed model of 3 treatments and 6 samples, with sampling nesting in the treatments. A variance analysis was performed to analyze the data; the Tukey-Kramer test a variance analysis was used in the cases with significant differences. No significant differences (p˃ 0.05) were found for hematocrit, protein, glucose, cortisol, and lactate. The insulin and T3 showed differences among treatments on day 35, but not on day 84, the same as cholesterol and hepatic glycogen. Triglycerides showed differences throughout the study, SR showed the lowest levels on day 84. The results allow us to conclude that, despite the partial feed restriction, there were no adverse effects on the metabolism of Brycon amazonicus.

Paisajes culturales y alteridad caribeña en el diario de “Viage a la America” de fray Íñigo Abbad y Lasierra
Authors: Rodríguez Velásquez Fidel
Published: October 2018

El presente trabajo estudió la construcción de paisajes culturales y alteridades caribeñas en el diario de “Viage a America” de fray Íñigo Abbad y Lasierra (1772-1774). Para ello se realizó un análisis textual de su crónica cotidiana de sucesos en la travesía por las islas de Puerto Rico, Margarita y Trinidad, con el objeto de dar cuenta de la forma como él vivió las geografías, personas, animales y costumbres de estas regiones. El relato de este fraile benedictino puede entenderse a partir de dos dimensiones, una antropológica que expone el universo cultural del propio viajero en el cual se encontraron elementos de la ilustración europea con elementos de la Europa medieval, y una dimensión sociohistórica que señala los esfuerzos de este viajero por ver la región como un espacio atrasado pero con una potencialidad importante que ha sido poco aprovechada por quienes habitan estas regiones y por quienes fueron enviados por la corona española para hacerlo. De estas dos dimensiones emergen los paisajes culturales que fray Íñigo Abbad y Lasierra representa textualmente en su diario de viaje.

Os dados sugerem que as atividades de mídia-educação suscitaram respostas positivas para a aprendizagem de línguas, além de promover o desenvolvimento de habilidades para analisar criticamente as culturas de mídia, como identificar significados ocultos e compreender processos de codificação e decodificação.
Skolans statliga uppdrag
Authors: Berg Gunnar
Published: October 2018

What tasks constitute the basis of the mission that the school as an institution is expected to fulfill in the Swedish society? In this article, I attempt to problematize that question. Few would oppose the notion that the school’s mission includes passing on knowledge as well as social norms. But what kind of knowledge should be put first in the day-to-day activities, and which social norms can and should be given priority? I argue that the school’s mission can be divided into two basic categories, here labeled competence development and cultural reproduction. The aim of the former is to educate the students with present and future societal needs in mind, focusing on growth ­– i.e. preparing the future labor force, taking macroeconomic and production factors into account. The task of cultural reproduction, on the other hand, is based on the notion of liberal education, where the aim is to reproduce societal values such as cultural heritage, democracy and citizenship. The difference between these two categories and their respective goals creates a number of tensions, resulting in a high degree of complexity in the daily school activities. Nevertheless, there are areas where the two categories at least partly intersect, meaning that the possibility of reaching a consensus does exist.
Samhällsförändringar, globalisering och internationell och jämförande pedagogik
Authors: Daun Holger
Published: October 2018

Utbildningen och dess funktion i ett land kunde länge förstås utifrån ett holistiskt, nationellt perspektiv. Verkligheten har emellertid förändrats väsentligt under de senaste decennierna – ofta på oförutsägbara sätt, främst på grund av den tilltagande globaliseringen. Utbildningssystemets huvudsakliga uppgift har varit att kvalificera människor för deras roller som producenter, konsumenter och medborgare. Men numera förväntas utbildningen också alstra humankapital som är konkurrenskraftigt globalt (Brown, Halsey, Lauder & Stuart Wells, 1997a, 1997b). Detta har förändrat villkoren för forskningen och undervisningen inom jämförande och internationell pedagogik (JIP) (Crossley & Watson, 2003). Under de sex, sju decennier som JIP existerat som en särskild disciplin har ämnet genomgått väsentliga förändringar – från spridda småskaliga (och ofta amatöristiska) fallstudier – ofta av något utbildningssystem eller några få skolor – och enstaka storskaliga och kvantitativt orienterade studier, till ett brett forskningsfält med alltmer heterogena objekt eller ämnen och en kombination av metodiska och teoretiska ansatser. Min forskning började med studier av utvecklingsproblematik och inlärning i låginkomstländer i Afrika och hamnade till sist i globalisering, omstrukturering och styrning av utbildningssystem. Den här artikeln försöker ge en schematisk översikt över utvecklingen inom JIP under de fyra, fem senaste decennierna. Först beskriver jag några av samhällsförändringarna och vilka begrepp, objekt, teman etccetera som tillkommit sen 1960- och 1970-talen på JIP:s forskningsagenda. Därefter tar jag upp några av JIP:s teoretiska och metodologiska ansatser.
Effect of denaverine hydrochloride application to heifers on the APGAR score and lactate concentration in newborn calves
Authors: Lange Katrin , Fischer-Tenhagen Carola , Heuwieser Wolfgang
Published: October 2018

Objective: The aim of this study was to evaluate the influence of Denaverine hydrochloride (DNH) in heifers on calf vitality. Material and methods: A total of 83 calvings with 38 female and 45 male calves were included in the study. Thirty minutes after onset of stage 2 of calving, 400 mg DNH or placebo (0.9% NaCl) were administered subcutaneously. If the calving procedure was not completed after 60 minutes, an extraction was conducted and pulling force was measured by using a digital force gauge. Directly after parturition, vitality of calves was evaluated using a modified APGAR score. Additionally, lactate concentration in blood from Vena auricularis was measured with a handheld measuring device (lactate scout). Results: No effect of treatment was observed on APGAR score and lactate concentration. Clinical relevance: Denaverine hydrochloride is a regularly used substance in obstetrics in veterinary medicine in many European countries. We could not confirm our hypotheses that treating heifers with DNH has a positive effect on calf vitality evaluated by APGAR score and lactate concentration in blood.

Analysis of cement-treated soil slab for deep excavation support – a rational approach
Authors: Pan Yutao , Liu Yong , Lee Fook Hou , Phoon Kok Kwang
Published: October 2018

In this study an effective stress model for cement-treated soil is employed to carry out a systematic study on cement-treated soil slab used to control the wall displacement in excavations with thick, soft clay layers. Deterministic analyses were first conducted to assess the drainage state of the treated soil slab. These indicate that, under timescales which are representative of those in actual construction, cement-treated soil slab conditions may range from nearly undrained to drained. Random finite-element analyses also show that the global undrained and drained behaviour of the treated soil slab differ significantly. Undrained loading leads to a rapid rise in stress with strain to a peak strength with subsequent softening. Drained behaviour, on the other hand, leads to a more compliant response, which suggests that the main issue in the drained condition is likely to be large displacement, rather than complete collapse. A rational design framework for cement-treated soil slab is proposed, which explicitly considers the distribution in global behaviours of the treated soil slab. This differs from current limit state approaches which are largely based on statistical properties of the input data, such as the unconfined compressive strength of sampled cores.

Authoritative discourse in a locally-published ELT textbook in Thailand
Authors: Jindapitak Naratip , Boonsuk Yusop
Published: October 2018

This study examines cultural contents in a locally-published English language teaching (ELT) textbook for primary 6 students in Thailand. It aims to investigate whether the locally-published textbook depicts sources and themes of cultures in a way that perpetuate and reproduce dominant ideologies and how cultural contents in the locally-published textbook were dealt with by an English teacher in the classroom. Grounded on Bakhtin’s notions of authoritative discourse and internally persuasive discourse, the findings revealed that there were mismatches between the cultural representation in the textbook and students’ lived experiences. Concerning how cultural contents were represented in the classroom, there was no evidence that the teacher assisted learners to forge effective linkages between authoritative discourse and their everyday life. The findings are discussed regarding how cultural contents are ideologically depicted in the textbook and how the cultural contents adversely affect students’ learning experience. Implications and recommendations for textbook authors, language teachers, and future research are presented.
The representation of Indonesian cultural diversity in middle school English textbooks
Authors: Parlindungan Firman , Rifai Irfan , Safriani Afida
Published: October 2018

In Indonesia, exposure to the English language is primarily mediated through the use of English textbooks. What cultural knowledge and whose culture are represented in these textbooks become a critical issue because culture interweaves both language and thought. With this in mind, this study aims to examine how Indonesian cultural diversity and whose cultures are represented in middle school English textbooks. We argue that diversity and multicultural perspectives represented in these textbooks are the core of English language learning and teaching. We also contend that language textbooks play a pivotal role in the acquisition of both linguistic and cultural knowledge of English. Drawing on Kress and Van Leeuwen’s (2006) semiotic approach to analyzing textual and non-textual representations of cultures, we found that the 2013 English textbooks for Grades 7 and 8 permeate Indonesian cultural values and practices that do not provide a balanced and equal depiction of Indonesian cultural diversity. The findings suggest the importance of inclusive representation of the richness of Indonesian local culture in a more salient manner, especially those of minority groups. Pedagogically, teachers are expected to design language materials with cultural sensitivity and appropriation for the inclusiveness of other cultural values that might not be covered in the textbooks.

As Malaysia sets out to realise their plan of the English Language Education Reform, the adaptation and implementation of Common European Framework of Reference (CEFR) is an obvious choice; however, creating a high-calibre teaching workforce to carry it out poses a significant challenge. This critical reflection article elucidates the implementation of CEFR in Malaysian Pre-, Primary and Secondary schools from the perspective of a National Master Trainer (NMT) who attended multiple courses by Cambridge English Super Trainers (CEST) before going on to train English language teachers using the Cascade Training Model. Based on the trainer’s experience, this article discusses the progress of the training, starting from CEST as the first tier, NMT as the second tier, and District Trainer (DT) as the third tier, until it reaches the teachers who will apply their knowledge and skills in the classroom. We conclude that despite the long and careful planning in terms of teacher training for the CEFR implementation, there are various aspects that need improvements, to better guarantee success in producing an English language programme along with international standards, as the plan dictates.
Vocational school EFL teachers’ practices of integrating ICT into English lessons: Teachers’ voices
Authors: Rodliyah Rojab Siti
Published: October 2018

Despite numerous studies on ICT-ELT integration, little is known about how English teachers in vocational schools in Asia and particularly in Indonesia integrate ICT into their English lessons. To fill this gap, this study aims to investigate how vocational English teachers integrate ICT into their English teaching practices in vocational high school settings. It specifically examines vocational high school English teachers’ reasons for using ICT, the ways the English teachers integrate ICT into their English lessons, and their perceptions of benefits and challenges of incorporating ICT into English classrooms. Guided by a case study design, three EFL teachers teaching at vocational high schools where ICT tools were readily available were recruited to participate in the study. Empirical data were collected through interviews and classroom observations. It was found that the teachers were self-motivated to use ICT in their English lessons due to their interests and positive attitudes towards ICT. This study also showed that the English teachers integrated ICT into their English lessons for different reasons. All the teachers agreed on the benefits of ICT-ELT integration to facilitate their learning and teaching process. They also shared the same view on the challenges they encountered when using ICT tools in the classroom. They voiced the need for training on ICT in ELT. This study highlights the importance of school support so as to promote ICT-based language teaching by providing adequate technology access and facilities as well as professional training in ICT for language teachers.

La corrupción en Colombia ha permeado las instituciones del Estado, estableciéndose como una forma de control los recursos y es un fenómeno que ha aumentado en los últimos años, la posible explicación a este comportamiento anómalo se debe a los acelerados procesos de transición de una sociedad que experimenta la modernización. Sin embargo, la inoperancia del Estado, la debilidad institucional para tomar decisiones de fondo que mitiguen el daño, se configuran como las principales causas que integran una triste realidad donde se colige un Estado que no ha podido establecer fronLa corrupción en Colombia ha permeado las instituciones del Estado, estableciéndose como una forma de control los recursos y es un fenómeno que ha aumentado en los últimos años, la posible explicación a este comportamiento anómalo se debe a los acelerados procesos de transición de una sociedad que experimenta la modernización.

FIQH AL-AQALLIYYAT AS AN AMERICAN VERSION OF LOCAL WISDOM
Authors: Mujiburohman Abas
Published: October 2018

Abstrak: Artikel ini membahas suatu bentuk kearifan lokal dalam kajian budaya hukum Islam yang berkembang di kalangan Muslim di Amerika Serikat, negara di mana mereka menjadi warga minoritas. Mengikuti Clifford Geertz dan ahli-ahli lain yang memahami hukum sebagai bagian dari kebudayaan, artikel ini berpendapat bahwa tradisi keagamaan sebuah komunitas pada akhirnya akan tumbuh dari konvergensi bermacam-macam tradisi yang dibawa oleh para individu Muslim dari kebudayaan asal mereka masing-masing. Malalui sebuah proses yang disebut dengan teritorialisasi, berbagai interaksi budaya dalam sebuah komunitas akan mengarah pada pengelompokan tiga macam tradisi: tradisi yang terus berlangsung, tradisi yang disesuaikan, dan tradisi yang disimpan. Praktek lokal sebagaimana yang disaksikan oleh penulis dalam penelitian lapangannya di kalangan Muslim kota Lansing, Michigan dapat dikategorikan sebagai tradisi kelompok kedua. Lebih jauh, kearifan lokal semacam ini telah ditemukan juga oleh para sarjana Muslim yang lain di Amerika. Di antara sarjana dimaksud, adalah Taha Jabir Al-Alwani yang mengajukan tawaran fiqh al-aqalliyyat, yang berisi himpunan praktek-praktek ajaran Islam yang mengalami penyesuaian terkait dengan status warga Muslim yang merupakan minoritas di negara tersebut.Abstract: This article discusses a type of local wisdom in the field of Islamic legal culture that is developing among Muslims of the United States as they are minority in the country. Using Clifford Geertz’ and others’ understanding of law as part of culture, this article is arguing that the eventual religious tradition of a local community will grow from the convergence of varied traditions brought by individual Muslims from their cultures of origin. Following a process called territorialization, cultural interactions within a local community will result in the production of three religious traditions: the continuing, the improvised, and the suppressed traditions. Local practice as witnessed by the writer in his field research among Muslims of Lansing, Michigan is categorized as part of the second tradition. Further, this kind of local wisdom has been observed among American Muslim scholars. Among them is Taha Jabir Al-Alwani who has proposed the term fiqh al-aqalliyyat for the collections of new practices of Islamic teachings that are related to the status of Muslims being minority in the country.
An Approach For Consumers Refunding Analysis Associated To Voltage Disturbances And Equipment Damages

Published: October 2018

This paper is aimed at presenting the fundaments towards a computational methodology to assist in the establishment of electro-electronic device performance analysis of consumers refunding. The strategy is based on the calculation of appliance dielectric and thermal stresses with different power system disturbances. Such strategy consists on a first orientation to support studies, analysis and reports about the decision of refunding consumers in such a complex subject. The approach is based on a time domain modeling and computational implementation of different electronic devices and power network elements into the ATP program to simulate the power system disturbances and the equipment performance. In this work, a typical TV device is taken to illustrate the proposed methodology. The dielectric and thermal stresses here considered are related with the occurrence of voltage swells, oscillatory transients and high-frequency impulse related to lightning strikes.

Authors: Özkan Yonca , Güler Seda
Published: October 2018

This study aims to investigate the perceptions of pre-service English language teachers towards the use of podcasts. In addition, it surveys to what extent the pre-service language teachers use Web 2 tools in their academic lives as well as in their personal lives and their views on the benefits and drawbacks of podcasts. The Teaching Language Skills Course designed specifically for the third year pre-service teachers is blended with podcasting in a web-based platform. Twenty-two pre-service language teachers who take the course constitute the working group. The theoretical background of this study is based on social constructivism and a mixed method research design is used. The questionnaire and face-to-face interviews are held at the beginning and the results are compared to see if there is a significant change. Results show that participants have a positive view of podcasts in general and have a tendency to use the podcasts in their following teaching career.
IDEJE KONSTRUKTIVIZMA U SAVREMENOJ ŠKOLSKOJ PRAKSI
Authors: Džinkić Olja , Milutinović Jovana
Published: October 2018

Ovim radom nastoji se prikazati trenutno stanje savremene školske prakse, sa fokusom na organizaciju i izvođenje nastavnog procesa. Cilj je da se utvrdi učestalost primene konstruktivističkih odnosno tradicionalnih elemenata u nastavi, kao i da se sagleda angažovanost i zainteresovanost učenika i njihova uloga u procesu učenja i poučavanja u odnosu na aktuelan pristup rada nastavnika. Istraživanje je sprovedeno na prigodnom uzorku od deset nastavnika osnovne škole, a korišćeni instrument bio je protokol posmatranja koji je kreiran za potrebe ovog istraživanja. Rezultati istraživanja ukazuju na dominantnost tradicionalnih elemenata nad konstruktivističkim u današnjoj školskoj praksi. Rezultati, takođe, pokazuju da je u nastavi sa elementima konstruktivizma prisutna povećana radoznalost i motivisanost učenika za nastavni sadržaj, te njihova veća angažovanost u nastavi. Zaključuje se da je trenutno stanje školske prakse u duhu tradicionalnog rada, a da obogaćivanje nastave konstruktivističkim elementima može rezultirati interaktivnom komunikacijom u odeljenju i učenika staviti u poziciju angažovanog pojedinca.
Emoções acadêmicas, autorregulação e seu impacto sobre motivação e aprendizagem
Authors: Bzuneck José Aloyseo
Published: October 2018

O texto se constitui em revisão da literatura mais recente sobre emoções acadêmicas e sua autorregulação. Com base em dados de pesquisa, são descritas emoções positivas e negativas, suas origens e seus efeitos sobre a motivação e o desempenho, à luz das teorias de atribuição de causalidade, de Weiner e de controle-valorização, de Pekrun.  Foram selecionadas as emoções negativas de vergonha, tédio e ansiedade, mais frequentemente focalizadas nos estudos, sobre as quais foram descritas diversas estratégias de autorregulação que os alunos podem usar nos contextos de aprendizagem. Foi discutida a relevância da teoria social cognitiva para explicar os processos de autorregulação, bem como para ajudar alunos a se tornarem capazes de regular emoções negativas. Por último, foram dadas sugestões de pesquisa futuras em nosso meio.
