Operational effects of speed breakers: a case study in India
Authors: Mohanty Malaya
Published: March 2021

Traffic condition in India is highly heterogeneous consisting of vehicles of different static and dynamic characteristics. The speeds of all vehicles are non-uniform. Therefore, to regulate the speeds of different category of vehicles while travelling on a sharp turn or while approaching towards an intersection or buildings like schools and hospitals, traffic calming devices are provided on the roads. Speed breakers are one of the most commonly used traffic calming devices in developing countries like India. Geometry of the speed breakers are based on IRC 99 which says that the width of speed breakers should be 3.7 m and the height should be 0.1 m for urban roads. The codal provisions also suggest that the vehicles should be able to cross the speed breaker at an advisory speed of 20 kmph. However, it is observed that most of the speed breakers have faulty geometrical dimensions owing to various problems to the road users. The width of the speed breakers are usually observed to be narrowed down which increases the chance of road crashes due to sudden braking of vehicles encountering it. Further, it also leads to sudden slowing down of the whole traffic stream leading to traffic congestion. It also reduces fuel efficiency of the vehicles leading to overall increase in vehicle operating and maintenance costs. The present study reviews in detail the provisions provided in the IRC code for construction of speed breakers. Thereafter, a practical on field study is conducted to examine the dimensions of various speed breakers across various cities in India, and compare their dimensions with the provisions provided in the IRC code. Further, the operating speed of the vehicles while crossing the speed breaker is also noted down and compared with the suggested speed as provided in the code. Finally, a detailed comparison between speed reduction at the speed breaker and their dimensions has been analyzed. Speed reduction of different category of vehicles has also been examined in detail.

Authors: Hannachi Hela , Elloumi Hanen , Khlifa Salma Ben , Hamdoun Manel , Kacem Khadija , Bahri Olfa
Published: March 2021

Background

Leukocytospermia (LCS) is implicated in male infertility since it was found in 30% of the infertile male. However, its influence on semen parameters remains controversial.

Aims and objectives

This study aimed to determine the impact of LCS on semen parameters and intracytoplasmic sperm injection (ICSI) results in infertile couples.

Materials and methods

A retrospective clinical study was conducted at Aziza Othmana Hospital of Tunis. Sperm parameters from infertile men were studied for volume, motility, vitality, and morphology according to seminal leukocytes. Intracytoplasmic sperm injection results were also compared to those observed in a control group matched by age, ICSI indication, hormonal profile, and endometrium thickness.

Results

No statistical difference was observed for all semen characteristics except the volume which was higher for the non-leukospermic group (p= 0.035).

Conclusion

Intracytoplasmic sperm injection outcomes were lower in the leukospermic group than the controls but the difference was not statistically significant.

Published: March 2021

Este texto tem por objetivo apresentar uma pesquisa que analisou de que modo as propostas para o estudo de Equações Diferenciais Ordinárias (EDO), presentes em livros-texto, podem contribuir no trabalho de professores de Matemática ao selecionarem situações-problema envolvendo o conceito de função. Os pressupostos teóricos para construção desta pesquisa referem-se a Abordagem Qualitativa e a Análise de Modelos Matemáticos. Optou-se por uma pesquisa qualitativa com a produção e análise dos dados seguindo pressupostos da Análise de Conteúdo. A fonte de produção de dados foi a análise de dois livros-texto de Equações Diferenciais mais citados por cursos brasileiros de Licenciatura em Matemática. A análise dos dados permitiu concluir que ambos os livros apresentam modelos matemáticos para estudar EDO, sendo as funções mais exploradas as exponenciais, quadráticas e trigonométricas, em detrimento da função logarítmica, não abordada nos capítulos analisados. Quanto a abordagem qualitativa, verificou-se que é utilizada, também, em ambos os livros, porém de forma limitada em um deles, pois não explora as potencialidades do campo de direções.
Avaliando o "PISA" Matemática
Authors: Liao Tarliz , Motta Marcelo Souza , Fernandes Cláudia de Oliveira
Published: March 2021

Este texto é movido por uma dupla intenção: analisar/problematizar o Programa Internacional de Avaliação de Estudantes (PISA), proposto pela Organização para Cooperação e Desenvolvimento Econômico (OCDE). Partimos de uma perspectiva que o entende como um dispositivo implicado na constituição dos “grandes mapas e projetos” para uma certa configuração da educação brasileira. Cabe ressaltar que este artigo trata somente das habilidades matemáticas refletidas pelo PISA, bem como tece considerações sobre especificidades dessa linguagem no processo de avaliação citado, no qual imergem alunos de várias redes educacionais e com realidades distanciadas.A metodologia adotada se configura em uma pesquisa bibliográfica, realizada em  documentos oficiais e outros, relacionados ao tema abordado. Ao final, pretende-se indicar que o Pisa, embora busque colaborar com alguns aspectos do ensino de matemática, têm o poder de desconsiderar elementos específicos de uma cultura, descartando conhecimentos historicamente e culturalmente instituídos e seu desenvolvimento apresenta, ainda, uma falibilidade.

Authors: Gonçalves Gustavo , Ribeiro Eduardo Boff , Karoleski Gregor Dimitri Teixeira , Mello Kelen Berra de
Published: March 2021

É importante que o professor promova o desenvolvimento de uma aprendizagem ativa e significativa, buscando métodos que visam a partir do concreto chegar no abstrato. Neste sentido, foi planejado e aplicado uma proposta de aula envolvendo este material concreto denominado Prédio Trigonométrico. A proposta utiliza da manipulação do objeto para obtenção de resultados do seno, cosseno e tangente dos ângulos notáveis, para então, por meio dequestionamentos, desenvolver resultados relativos aos valores desta relação. Após a atividade, foi aplicado um outro questionário perguntando sobre a efetividade do material para os alunos. Em grande maioria, os alunos elogiaram a aplicação, mostrando que foi um facilitador em sua aprendizagem. Além disso, percebemos que os alunos foram capazes de abstrair resultado como o valor das relações trigonométricas para o ângulo de 90°. Com isso, vemos um potencial na aplicação de tal metodologia, que pode auxiliar o professor no ensino de trigonometria no Ensino Fundamental e Médio.

Published: March 2021

Objective: To estimate the prevalence of co-occurrence of alcohol, tobacco, and illicit drug use among students at a public university in a municipality in Southern Brazil, and to evaluate the factors associated with this practice. Methods: Cross-sectional study conducted with undergraduate students between November 2017 and July 2018, to whom a digital self-administered questionnaire was applied. The relationship between the dependent variables co-occurrence of alcohol, tobacco, and illicit drug use and co-occurrence of alcohol and illicit drug use was analyzed using binary logistic regression with a 95% confidence interval. Results: Of the 1,824 university students, 92.0% consumed alcohol in their lifetime, 11.0% smoked, 43.9% used at least one illicit drug in their lifetime, and 23.3% used at least one illicit drug in the last 30 days. The rate of co-occurrence of alcohol, tobacco, and illicit drug use was 5.2%, and it was associated with belonging to the highest economic class (p = 0.0003), experimenting with drugs before the age of 18 (p = 0.0013), and attending an exact sciences or land/agricultural sciences program (p = 0.0386). The prevalence of co-occurrence of alcohol and illicit drug use was 13.6%, and it was associated with belonging to the highest economic class (p = 0.0000), male gender (p = 0.0323), depression (p = 0.0001), experimentation with alcohol before the age of 18 (p = 0.0000), attending a linguistics or arts and literature program (p = 0.0314) and living alone/with friends (p = 0.0000). Conclusion: The co-occurrence of alcohol and drug use was higher than the co-occurrence of use of the three substances, and factors such as experimenting with drugs before the age of 18 and being of higher economic status were associated with these patterns.

Transformational Leadership and its Dimensions: Contributions in
Organizational Change among Schools
Authors: Milan Shrestha Milan Shrestha
Published: March 2021

Transformational leadership incorporates the charismatic and affective portions of
leadership and accelerates the change in the organization. Thus, this paper aims to
discuss the model of transformational leadership in terms of its dimensions and its
contributions in organizational change particularly in educational sectors by
reviewing its literature. On the basis of literature, the idealized influences, inspirational motivation, intellectual stimulation, and individual consideration collectively composed the transformational leadership. Due to this broad nature of composition, transformational leadership is useful in every kind of situation and it promotes the change process in the organization. Furthermore, the transformational leadership changes the organization and it reveals the high levels of performance and satisfaction. Thus, transformational leadership is a better approach to address the issues than other leadership models.

Since the passage of the Elementary and Secondary Education Act of 1965, over 300 billion dollars have been funneled to schools through Title I funds. Qualifying school districts receive Title I funds to address disparities between disadvantaged students' academic achievement and their less impoverished peers. Substantial research has focused on the impact of funding and other significant factors on student achievement. One such significant factor impacting student achievement is chronic absenteeism, which is associated with lower student performance. Students from disadvantaged environments are more likely to miss school than students from higher-income families. This causal-comparative examination investigates the effects of a mentoring program on disadvantaged students in an urban secondary school. The findings reveal that students participating in mentoring for extended periods demonstrate significantly fewer absences, resulting in higher grade point averages. These findings indicate that low-budget school mentoring programs have a positive impact on absenteeism and student achievement.
The Emerging Critical Pedagogies of Dance Educators in an Urban STEAM After-School Program for Black Girls
Authors: Allen-Handy Ayana , Ifill Valerie , Schaar Raja Y. , Rogers Michelle , Woodard Monique
Published: March 2021

The preparation of urban educators has gained widespread attention across education policy, research, and practice. As US urban cities have become more diverse, the teacher workforce has not kept up, and the racial/ethnic demographics of students and teachers are disproportionately incongruent. In order to eradicate an education landscape that perpetuates white, middle-class ways of knowing and being, often at the expense of the cultural practices and cultural wealth of historically marginalized students of color, urban teacher education must be centered toward justice and rooted in critical pedagogies. The literature, albeit bleak, reveals that these perspectives must also be applied to urban dance education. Dance education programs have been significantly eliminated from urban schools over time, and although dance has historical roots in African and African diasporic cultures, dance education continues to be Eurocentric. This phenomenological case study examines the emerging critical pedagogies of undergraduate dance majors and minors who served as dance teachers in an urban Science, Technology, Engineering, Arts, and Mathematics (STEAM) after-school program for 7-12-year-old Black girls. Findings reveal that (a) navigating race, place, and space; (b) mentorship and practice; and (c) critical reflection and self-efficacy were critical components of the urban dance educators’ emerging critical pedagogies. Implications for urban dance education and the broader field of urban education are provided.
Using Photovoice as a Teaching Tool to Explore Pre-service Teachers' Perceptions of Students from Impoverished Backgrounds
Authors: Bazemore-Bertrand Shamaine
Published: March 2021

Despite the diversity of the American student population, the current teacher force and cohorts of future teachers are overwhelmingly white women from middle class backgrounds. In addition to the work around race, gender, and disability status, there is a clear need for us to help future teachers reconsider how they think about children experiencing poverty in urban schools and communities. Based on its use in an elementary education foundations course, this article provides a first-person accounting of how the pedagogical tool photovoice helped future teachers critically reflect on their perceptions of students from these backgrounds and offered their professor entry points for knowledge and skill development related to teaching students living in impoverished backgrounds.
Neural-variational algorithm adaptation from SeaWiFS to MODIS sensor for analysis of atmospheric and oceanic parameters
Authors: Correa Khassoum , Machu Eric , Demarcq Hervé , Diouf Daouda
Published: March 2021

Particularly interesting because of its socio-economic contribution, the Canary upwelling system encompasses a number of regions with very special characteristics. The wind that blow over this system induces a permanent upwelling off Mauritania and a seasonal upwelling in the south off Senegal, which boosts the development of phytoplankton. To refine the understanding of the phytoplankton in this region (its distribution, variability, response to physical forcings), we combine a number of tools and methods to arrive at a better estimate, and a better monitoring of the concentration of chlorophyll-a (Chl-a), an input parameter for primary production models. Remote sensing of ocean color has particularly interesting advantages, both in terms of global sampling and data acquisition frequency. This method is all the more interesting since ocean color algorithms can be adapted to reduce bias when standard methods have limitations. The regional ocean color algorithm called SOM-NV (Self-Organized Map-Neuro-variational) offers the advantage of making atmospheric correction in the presence of absorbent aerosols, especially desert dust, which sweeps this area permanently and which compels the standard algorithm to apply a mask when atmospheric optical thickness exceeds a threshold of 0.3. This contribution of SOM-NV in the process of atmospheric correction allowed us to 1 : obtain a better reflectance spectra, and as a consequence offer a better estimate of the Chl-a concentrations ; 2 : acquire a larger number of pixels by processing pixels with an optical thickness greater than 0.3 ; 3 : go beyond the general distribution towards the distribution of dominant groups according to the Physat spectral method. The synthesis of 16 years of data from the MODIS-Aqua sensor, allowed us to revisit the seasonality of Chl-a distribution and its cross-shore particularityand an extension towards the open sea which differs according to the season. The highest coastal values are measured in winter and spring, when upwelling intensifies, while the lowest values are measured in summer, when warm, nutrient-poor equatorial waters freplace upwelling waters along the Senegalese coast. This change in water masses impacts phytoplankton communities. According to the work of some authors, nanoplankton gradually replaces diatoms, known to be present during the upwelling season. This makes this region a particularly interesting zone for monitoring dominant groups of phytoplankton, knowing that the change in community impacts the upper levels of the marine food chain, with phytoplankton playing a leading role.

The transport of sediment mixtures examined with a birth-death
model for grain-size fractions
Authors: Chartrand Shawn M. , Furbish David Jon
Published: March 2021

Abstract. Bedload transport of sediment mixtures in mountain streams is challenging to predict, with implications for understanding how rivers form and respond to environmental change. Experimental work shows that collective particle entrainment is an important contributing mechanism of bedload transport, but questions remain. We use four different time series of experimental sediment flux for granular particles 4–32 mm in diameter to indirectly examine the role of collective mobilization. Flux was measured at a fixed position in space using an imaging light table. The light table provides a flux measurement that is sampled at a resolution of 1 Hz, and for total time durations ranging from 75 to 240 min. Experimental conditions include periods of statistical steady-state, and transient adjustments due to changes of the upstream supply of water and sediment. We find that despite the contrasting experimental conditions, the time series encode a consistent transport behaviour within the Fourier domain: the transport of finer grain size populations has increasing power density for decreasing frequency, whereas the transport of larger grain size populations has a near constant power density across all frequencies. Hence, smaller particle sizes dominate the power spectra. We seek an explanation for this result, and elaborate on a probabilistic birth-death model introduced to the field by Christophe Ancey and colleagues. Analysis using the expanded birth-death model provides two important results. The transport of smaller particles includes collective entrainment terms that represent grain mobilization due to smaller and larger particle sizes colliding with the streambed surface. In contrast, the transport of larger particles includes collective entrainment terms limited to larger particle sizes. The size-dependent collective controls on particle mobilization is an important finding, and we show that it offers a testable explanation for observed flux differences between smaller and larger particle sizes, common to gravel-bed mountain streams. As a result, our work motivates the need to better understand collective entrainment within the context of granular sediment transport along mountain stream beds.

Abstract. Epidote – here defined as minerals belonging to the
epidote–clinozoisite solid solution – is a low-μ (μ=238U/204Pb) mineral occurring in a variety of geological
environments and participating in many metamorphic reactions that is stable
throughout a wide range of pressure–temperature conditions. Despite
containing fair amounts of U, its use as a U−Pb geochronometer has been
hindered by the commonly high contents of initial Pb, with isotopic
compositions that cannot be assumed a priori. We present a U−Pb geochronology
of hydrothermal-vein epidote spanning a wide range of Pb (3.9–190 µg g−1), Th (0.01–38 µg g−1), and U (2.6–530 µg g−1) contents and with μ values between 7 and 510 from the Albula area (eastern Swiss Alps), from the Grimsel area (central Swiss Alps), and
from the Heyuan fault (Guangdong Province, China). The investigated epidote
samples show appreciable fractions of initial Pb contents (f206=0.7–1.0) – i.e., relative to radiogenic Pb – that vary to different
extents. A protocol has been developed for in situ U−Pb dating of epidote
by spot-analysis laser ablation inductively coupled plasma mass spectrometry
(LA-ICP-MS) with a magmatic allanite as the primary reference material. The
suitability of the protocol and the reliability of the measured isotopic
ratios have been ascertained by independent measurements of
238U/206Pb and 207Pb/206Pb ratios, respectively, with
quadrupole and multicollector ICP-MS applied to epidote micro-separates
digested and diluted in acids. For age calculation, we used the
Tera–Wasserburg (207Pb/206Pb versus 238U/206Pb)
diagram, which does not require corrections for initial Pb and provides the
initial 207Pb/206Pb ratio. Petrographic and microstructural data
indicate that the calculated ages date the crystallization of vein epidote
from a hydrothermal fluid and that the U−Pb system was not reset to younger
ages by later events. Vein epidote from the Albula area formed in the
Paleocene (62.7±3.0 Ma) and is related to Alpine greenschist-facies
metamorphism. The Miocene (19.2±4.3 and 16.9±3.7 Ma)
epidote veins from the Grimsel area formed during the Handegg deformation
phase (22–17 Ma) of the Alpine evolution of the Aar Massif. Identical
initial 207Pb/206Pb ratios reveal homogeneity in Pb isotopic
compositions of the fluid across ca. 100 m. Vein epidote from the Heyuan
fault is Cretaceous in age ( 107.2±8.9 Ma) and formed during the
early movements of the fault. In situ U−Pb analyses of epidote returned reliable ages of otherwise undatable epidote–quartz veins. The
Tera–Wasserburg approach has proven pivotal for in situ U−Pb dating of
epidote, and the decisive aspect for low age uncertainties is the variability
in intra-sample initial Pb fractions.
Analytical Solution for the Influence of Irregular Shape Loads Near
the Borehole Strain Observation
Authors: Yan Wei , Li Zirui
Published: March 2021

Abstract. Based on the analytic displacement solution caused by the punctate load model, we derived the calculation formulas of peripheral strain Field. This method can provide a theoretical basis for the quantitative calculation of the load influence of borehole strain observation. On this basis, using the superposition principle, we present a method for calculating the strain effect of two-dimensional and three-dimensional irregular shape loads. The results show that: (1) To solve the problem of two-dimensional irregular shape load model, we can calculate it by vector superposition after load scattering. (2) To solve the problem of three-dimensional irregular shape load model, we can use the two-dimensional irregular shape load method to calculate with assigning different weights to the scattered points after the load scattering. (3) There are obvious convergence processes in the vector superposition process after scattering of two-dimensional and three-dimensional irregular loads, which shows the correctness and feasibility of the calculation method. (4) The calculation method introduced in this paper can provide a research basis for quantitative analysis of influence of disturbance of peripheral load in borehole strain observation.

Abstract. The Thwaites Eastern Ice Shelf (TEIS) buttresses the eastern grounded portion of Thwaites Glacier through contact with a pinning point at its seaward limit. Loss of this ice shelf will promote further acceleration of Thwaites Glacier. Understanding the dynamic controls and structural integrity of the TEIS is therefore important to estimating Thwaites' future sea-level contribution. We present a ~20-year record of change on the TEIS that reveals the dynamic controls governing the ice shelf's past behavior and ongoing evolution. We derived ice velocities from MODIS and Sentinel-1 image data using feature tracking and speckle tracking, respectively, and combined these records with ITS_LIVE and GOLIVE velocity products from Landsat 7 and 8. In addition, we estimated surface lowering and basal melt rates using the REMA DEM in comparison to ICESat and ICESat-2 altimetry. Early in the record, TEIS flow dynamics were strongly controlled by the neighboring Thwaites Western Ice Tongue (TWIT). Flow patterns on the TEIS changed following the disintegration of the TWIT in ~2008, with a new divergence in ice flow developing around the pinning point at its seaward limit. Simultaneously, the TEIS developed new rifting that extends from the shear zone upstream of the ice rise and increased strain concentration within this shear zone. As these horizontal changes occurred, sustained thinning driven by basal melt reduced ice thickness, particularly near the grounding line and in the shear zone area upstream of the pinning point. This evidence of weakening at a rapid pace suggests that the TEIS is likely to fully destabilize in the next few decades, leading to further acceleration of Thwaites Glacier.

Anglophone culture through the Western Balkan lens: a corpus-based study on the strategies used for rendering extralinguistic elements of culture in Montenegrin subtitling
Authors: Božović Petar
Published: March 2021

One of the most demanding aspects of intercultural communication is rendering the elements of foreign culture from source to target linguocultural system. As today more people are exposed to audiovisual than any other form of text, cultural representation is an important issue as these texts can be a powerful tool for construction or deconstruction of cultural and sociological stereotypes, dissemination of ideas, facilitating intercultural communication, etc. Hence, this study attempts to shed light on how the Anglophone culture is rendered in subtitling and what could be some underlying reasons for that. To this end, we have constructed a morphosyntactically annotated parallel English – Montenegrin corpus of TV subtitles consisting of 110 episodes of three different TV series that were broadcast on the public service broadcaster of Montenegro and scrutinized it to map the strategies used for rendering extralinguistic elements relying on the analytical framework proposed by Pedersen (2011).
El debate en la prensa sobre libertad académica. El caso Finnis
Authors: De Lucas Vicente Alberto
Published: March 2021

En el debate acerca de la libertad de expresión en el ámbito académico, el caso Finnis ha sido uno de los más recientes y de los que más repercusión mediática ha recibido. La petición creada por un grupo de alumnos de la Universidad de Oxford para despedir a John Finnis generó múltiples reacciones en prensa y en redes sociales. Al hablar de discursos que hablaban a su vez de otros discursos anteriores, el estudio lingüístico desde la perspectiva de la polifonía y la argumentación en la lengua (Anscombre y Ducrot 1983) se muestra como el más adecuado para el análisis del tratamiento que los medios dieron al debate (Bednarek 2006, 2007, Fairclough 1988, Smirnova 2009). En este trabajo se han analizado las estrategias de (des)legitimación empleadas para introducir discurso ajeno. A continuación, se ha analizado la presencia que cada medio daba a los distintos agentes sociales implicados en el debate.
