Stochastic Model on Three-Similar Units Three Phased Mission System with FCFS Repairs Pattern
Authors: Kumari Sudesh , Kumar Rajeev
Published: May 2021

The paper allocates a stochastic model on threesimilar units three-phased mission system. The developed system
consists of units working in parallel, series and parallel
configurations respectively. Initially, the three similar units are
operational. Each component has only three states: good,
degraded and failed. In this case, the single repair facility that
repairs the units in first come first serve (FCFS)pattern has been
thought of. Using Semi-Markov Process and regenerative point
techniques, various measures of the system performance at each
phase are obtained. The system has been analyzed graphically
taking a particular case. Various conclusions are made regarding
the reliability and cost consideration of the system at each phase
as well as for the whole system(as combined Phase I, Phase II,
Phase III).
Face Mask Detection System using Mobilenetv2
Authors: Arora Mayank , Garg Sarthak , A. Srivani
Published: May 2021

In this pandemic, it is getting more and more difficult
to keep a track of people who are wearing masks regularly or not.
It cannot solely depend on human efforts to take care of this task
and therefore there is a need to develop software that can
automatically detect whether any given person is wearing a mask
or not. Face Detection has evolved as a really popular problem in
image processing and computer vision. Many new algorithms are
being devised using convolutional architectures to form the
algorithm as accurately as possible. These convolutional
architectures have made it possible to extract even the pixel
details. Training is performed through Fully Convolutional
Neural Networks to semantically segment out the faces present in
that image. Feature detection and feature extraction techniques
help us identify whether a person is wearing a mask or not. The
face mask detector will use a dataset of morphed masked images.
Therefore, the created model will be accurate and it will also be
computationally efficient and easily deployable in embedded
systems since the MobileNetV2 architecture will be incorporated
(Raspberry Pi, Google Coral, etc.). This framework can also be
used in real-time applications that, due to the outbreak of
Covid-19, require face-mask detection for safety purposes. This
project can be merged with embedded application systems at
airports, train stations, workplaces, schools, and public places to
ensure compliance with the guidelines for public safety. The
above topic is very prominent in recent times as the identification
process will not only help us classify individuals but also will
reduce the workforce required to do the same exponentially.
Experimental Study on Water Percolating Concrete
Authors: Murthy Ayapilla Narasimha
Published: May 2021

This paper addresses two aspects namely a new
method for manufacturing of percolating concrete blocks using
different proportions of concrete mixture such as Portland
cement, Coarse aggregates, fine aggregates, limestone, and water
have been designed. Apart from this an attempt has also been
made by adding small quantities of additives such as fly ash, rice
husk ash etc. for its strength and suitability on par with the
normal Concrete blocks.
Another is a partial replacement of cement with supplementary
cementation materials such as fly ash and metakaolin in different
proportions for reducing high grade cement consumptions been
proposed.
The design of a Pervious Concrete is made in such a way that it
allows the entire surface run off water to percolate down without
retaining any drop/quantity in it. Thus, it is named as water
percolating Pervious Concrete/ porous concrete. An alternative
for reducing cement usage in concrete makes concrete
eco-friendly. Thus, there comes an idea of partially replacing
cement with supplementary cementations materials,
The concern has been growing in recent years towards
reducing the pollutants in water conservation and the
environment. The continual urbanization has led to the increase
in impervious surface area of the cities, further leading to
blockage in percolation of precipitation from rainfall. This result
is excess surface run off. To counteract this, pervious concrete is
the solution. Hence, the pervious concrete having 15% to 35%
interconnected pores by volume, allows direct infiltration of water
through its structure. Since the strength of this block for highway
suitability of roads is not yet tested. The main aim of this paper is
to improve the strength characteristics of porous concrete.
However, on comparison, with the published data it is suitable for
foot paths/ pathways and parking lots and as driveways in the
residential and small rural areas where less vehicular traffic. This
will help in reducing the risk of water clogging and recharges the
nearby ground water level. The Maintenance of the slab is also
minimum and can be repaired and cleaned easily. Thus, it is
worthy and useful in many ways
A Secure Based Preserving Social Media Data Mangement System

Published: May 2021

Personalized suggestions are important to
help users find relevant information. It often depends on huge
collection of user data, especially users’ online activity (e.g.,
liking/commenting/sharing) on social media, thereto user
interests. Publishing such user activity makes inference
attacks easy on the users, as private data (e.g., contact
details) are often easily gathered from the users’ activity
data. during this module, we proposed PrivacyRank, an
adjustable and always protecting privacy on social media data
publishing framework , which protects users against frequent
attacks while giving personal ranking based
recommendations. Its main idea is to continuously blur user
activity data like user-specified private data is minimized
under a given data budget, which matches round the ranking
loss suffer from the knowledge blurring process
so on preserve the usage of the info for enabling
suggestions. a true world evaluation on both synthetic and
real-world datasets displays that our model can provide
effective and continuous protection against to the info given
by the user, while still conserving the usage of the blurred
data for private ranking based suggestion. Compared to other
approaches, Privacy Rank achieves both better privacy
protection and a far better usage altogether the rank based
suggestions use cases we tested.

Estrategias enunciativas en el discurso irônico: un artículo de opinión de José-Ignacio Cabrujas
Authors: Espar Teresa
Published: May 2021

En el análisis semântico y semiótico del discurso (Escuela de París y escuela francesa de análisis del discurso), cualquier unidad micro o macro-estructural puede constituir un punto de partida esclarecedor para reestablecer la arquitectura del sentido. Partiendo del análisis de los lexemas, responsables de la constitución de las isotopías temáticas y figurativas (Greimas, 1968) en su condición de unidades semânticas mínimas del sistema de la lengua, propondremos la explicación y la interpretación de un artículo de opinión de José-Ignacio Cabrujas (Caracas, 1937- 1995). El análisis de los mecanismos de construcción dei simulacro discursivo que provienen de la instancia de la enunciación (Benveniste, Greimas y Courtés) considerada como unidad macro-estructural, permitirá un acercamiento a los recorridos laberínticos dei decir, que al mismo tiempo representa nuestras formas de vida (Wittgenstein), aserta, manipula, actúa, nos hace sentir (Searle, Austin, Ducrot, Greimas y Fontanille) y nos induce a la sonrisa de la distancia irônica o al gesto amargo dei sarcasmo. La densidad semântica del discurso irónico nos servirá de pretexto para mantener nuestra posición crítica ante las dificultades de micro-análisis semântico del discurso.

Cómo “hacer hacer” cosas con palabras. La construcción discursiva del estereotipo femenino en la publicidad de los 90
Authors: Cucatto Mariana
Published: May 2021

El objetivo del siguiente trabajo consiste en reconocer las estrategias discursivas presentes en un Corpus de publicidades femeninas aparecidas durante el período octubre de 1999 a abril de 2000 en la revista semanal Viva del diario argentino Clarín. En una primera instancia se elaborará el marco teórico y metodológico en el que se encuadrará la investigación y se diseñará el Corpus correspondiente. Luego se llevará a cabo la tarea de análisis a partir del establecimiento de los niveles de la materialidad discursiva, semántico-funcional, enunciativo, pragmático e ideológico con el objeto de postular un conjunto de estrategias, denominadas de reificación, analogía, discriminación y tipificación cuya identificación y valoración permitirá comprender los diversos procedimientos de marcación lingüística utilizados en la construcción del sentido discursivo. Por último, se mostrará cómo dichas estrategias, de carácter fuertemente persuasivo, tienen como finalidad reproducir determinados estereotipos culturas vigentes en la sociedad Argentina de los 90, cifrados en la analogía ser delgado-ser bello- ser exitoso.
Discurso autobiográfico e identidad sociocultural
Authors: Ruiz Ávila Dalia
Published: May 2021

El tipo de discurso, la operación discursiva y el patrón de producción textual son determinantes para que los sujetos adopten estrategias acordes con la práctica discursiva que realizan. En este artículo se analizan quince discursos autobiográficos, referentes y expresión de diferentes dimensiones del fenómeno identitario, que pertenecen a tejedores de sombreros de un pueblo maya del Estado de Campeche; se inscriben en la narración como operación discursiva básica y pertenecen al patrón de producción textual oral. Narración y oralidad marcan el funcionamiento del tejido intertextual de este tipo discursivo y destacan símbolos, lugares comunes, espacios, tiempos específicos, auto representaciones (valores y estereotipos), implícitos y figuras retóricas que dan cuenta de las potencialidades, necesidades y expectativas de los sujetos que interactúan en un ámbito sociocultural determinado. En esta perspectiva teórico-metodológica se inspira la realización de este trabajo; se trata de hacer un análisis del discurso autobiográfico que permita describir y explicar los mecanismos de constitución y de confirmación de la identidad sociocultural.

El estatuto de la subjetividad en la teoría polifónica de la enunciación
Authors: Bertorello Adrián
Published: May 2021

El trabajo se propone discutir el rol que cumple la subjetividad en la teoría polifónica de la enunciación de Ducrot. La tesis que desarrolla es la siguiente: existe una contradicción entre el punto de partida que Ducrot asume, a saber, el supuesto saussuriano de la inmanencia del análisis lingüístico con su propuesta de una diversidad de roles subjetivos que hablan en los enunciados. Sólo rompiendo con la inmanencia lingüística y adoptando una teoría de la subjetividad histórica muy cercana a la de Bajtín es posible sostener la idea de una enunciación polifónica. Finalmente, el trabajo propone una reorganización de los roles subjetivos polifónicos a partir de las nociones de modalidad y deixis.

El juego como derecho de los niños y las niñas, el devenir de la escuela en ámbitos donde el maestro de infancias configura un discurso, un pensamiento y unas prácticas basados en la transversalidad del juego y la lúdica; la palabra del docente y el gozo por la participación, en una escuela que es direccionada por la infancia. Estas premisas mueven este texto, en el cual se hace un reconocimiento a los maestros de infancia, quienes desde su cotidianidad tienen la potestad de generar felicidad a los niños y niñas, a la vez que los orientan mediante la lúdica y la libertad. Este texto pone sobre la mesa propuestas que permiten que el maestro se lea como el dispositivo preciso para que en la educación infantil se generen prácticas pedagógicas y evaluativas movidas por los niños y las niñas, por sus intereses, por su libertad y creatividad. A la vez, se reconoce que la infancia tiene derecho a jugar y participar, lo que conlleva a que el maestro, como garante de los derechos de los niños y niñas, propicie y asegure esta participación de la infancia en todas las decisiones que lo acojan. Esta propuesta está dedicada a los maestros, a los maestros de infancia. Para ellos; se basa en premisas que describen realidades de la infancia, esa infancia que no se encuentra enmarcada por parámetros biológicos, por etapas de desarrollo o crecimiento, aquella infancia descrita por Kohan (2009) al decir que “La infancia es un grito. Seco, prolongado, intermitente: una voz sin palabra, la infancia es puro grito… la infancia es un grito de voz que hace vibrar las palabras” (p. 5). Se dedica esta propuesta al maestro que se comprende a sí mismo como el dispositivo para permitir que ese grito se de en libertad.

Creating Project-Based Learning for Online Art Classrooms
Authors: Lai Alice
Published: May 2021

Project-based learning (PBL) is considered an engaging and promising pedagogy across diverse disciplines and student populations in the United States in the digital age. Research on PBL in online environments and in the field of art has, however, been limited. Thus, the purpose of the current study was to examine the theoretical grounds of PBL and analyze its pedagogical features and application. Of specific interest is Krajcik and Shin’s (2014) PBL model, which includes six pedagogical features: asking driving questions, emphasizing learning goals, fostering authentic practice, enhancing collaboration, learning with technology, and creating artifacts. An account of a qualitative descriptive pilot study conducted in an undergraduate online art course further explicates the application of this PBL model. The pilot study accentuates ways to create an online PBL art classroom and illustrates students performing PBL through their arts-based research projects. Reflection on pedagogical recommendations and the challenges of implementing PBL in the online art classroom concludes the study.
MEASURING TRANSOPRT EFFECTIVENESS WITHIN A SUPPLY CHAIN APPROACH
Authors: Ahmed Laghouag Abderrazak , Ali Sahli Alhussain
Published: May 2021

In an economic context strongly characterized by the amplication of transactions, translated by a very
increased competition, transport becomes a vital factor of competitiveness since it represents an
important component of the cost price of products as well as it allows processes integration between the different logistics actors.
Adopting best practices in terms of transportation management by companies seems to be a strategic factor for competitiveness.
The purpose of this study is to assess the maturity of transport practices using an SC auditing. This audit is illustrated by the
application of the ASLOG standards in an Algerian SME operating in the food sector. The ASLOG model allows to highlight all
the strengths and weaknesses of transport logistics in order to be able to set up and follow a progress plan that consolidates the
strengths and improves the weaknesses.
Evaluation of Methods Adopted for Training Students in the Use of Quantity Surveying Software Packages in Tertiary Institutions in Nigeria

Published: May 2021

Effective training through selection of suitable methods is imperative for students to acquire necessary skills and competences required for employment. Suitability of the methods adopted for training the students the use of dedicated quantity surveying software packages is in doubt due to the increasing rate of unemployment among the graduates. Hence, this paper examined the methods adopted for training the students with a view to determining their suitability. Primary data were obtained through questionnaires administered virtually through email and WhatsApp social medium due to COVID-19 pandemic on the total population of 21 lecturers responsible for training the students in the 20 fully accredited tertiary institutions in the country. In addition, secondary data were obtained from the end of the semester students’ raw score sheets of the ICT courses from the lecturers’ records. A total of 18 properly completed questionnaires representing 85.7% return rate, were received via email and WhatsApp social medium. The data obtained were analysed with descriptive and inferential statistics such as means, percentages, and Cramer’s V test using IBM Statistical Package for Social Sciences (SPSS) version 25. The results obtained revealed that the lecturers were not academically qualified in both ICT and pedagogy thus playing roles they were not trained for. It further revealed that the lecturers were adopting only two forms of traditional training method (Lecture and Discussion) which could not produce the required learning outcome. Thus, the study concluded that the adopted methods of training were unsuitable and recommended capacity building in both ICT and Teaching for the lecturers.
Effects of Grassland Fire on Selected Properties of Soil in the Savannah Region of Nigeria
Authors: Abdulraheem K. A.
Published: May 2021

The effects of fire on soil properties have been widely studied in different ecosystems globally. However, only limited studies exist in the savanna tropics of Africa with mostly inconsistent results. The objective of this study is to characterize the effects of different fire intensities on soil properties in the Guinea Savannah of Nigeria through laboratory experiments. Three different grass species (Eleusine indica, Cynodon dactylon and Imperata cylindrica) and soils were collected from the forest zone of the University of Ilorin and prepared for laboratory investigation. Experimental fires were simulated in the laboratory to replicate field burning conditions on the prepared plots to determine precise effects of fire on soil properties. Three fire treatments (low, moderate and high) were considered, while the pre-burning and post burning samples of soils were taken for laboratory investigation, and the results statistically analyzed. The pH was observed to have increased between the range of 7.92 to 8.37. The average percentage decrease in organic matter content is 5%, 33% and 69% for low, moderate and high fire intensities, respectively. For total nitrogen, 8%, 16%, and 19% increase; calcium, 17%, 117% and 283% increase; magnesium, 11%, 30% and 84% increase; sodium, 7%, 20% and 54% increase; potassium, 24%, 20% and 49% decrease; available phosphorus, 8%, 18% and 29% increase. The results show the impacts of prescribed fire in the management of savanna ecosystem..
Evaluation of some selected soil properties of a drip irrigated tomato field at different moisture regimes in South-Western Nigeria

Published: May 2021

Soil properties are important to the development of agricultural crops. This study determined some selected soil properties of a drip irrigated tomato (Lycopersicon esculentum M.) field at different moisture regime in South-Western Nigeria. The experiment was carried out using Randomized Complete Block Design with frequency and depth of irrigation application as the main plot and sub-plot, respectively in three replicates. Three frequencies (7, 5 and 3 days) and three depths equivalent to 100, 75 and 50% of water requirement were used. Undisturbed and disturbed soil samples were collected from 0-5, 5-10, 10-20 and 20-30 cm soil layers for the determination of some soil properties (soil texture, organic matter content, bulk density, infiltration rate and saturated hydraulic conductivity) were determined using standard formulae. Soil Water Content (SWC) monitoring was conducted every two days using a gravimetric technique. The soil texture was sandy loam for all the soil depths; average value of soil organic matter was highest (1.8%) in the 0-5 cm surface layer and decreased with soil depth; the soil bulk density value before and after irrigation experiment ranged from 1.48 and 1.73 g/cm3 and 1.5 and 1.76 g/cm3, respectively; there was a rapid reduction in the initial infiltration and final infiltration rate. Saturated hydraulic conductivity show similar trend although the 20-30 cm layer had the lowest value (50.84 mm/h); the SWC affect bulk density during the growing season. The study showed that soil properties especially bulk density and organic matter content affect irrigation water movement at different depth..

Published: May 2021

The study examined a review of literature on African cultural belief on housing development and ownership by women, barrier and ways for management. Studies on gender and housing have focused on roles of women in housing development and involvement in decision making. The paper observed that in development of housing, women face challenges as cultural factors affect involvement in housing developments processes. Also, socio-cultural and traditional practices, norms and beliefs inhibit women’s engagement in housing developments processes. The study recommends government policies should be enacted to encourage female participants in housing development processes and patience is needed to achieve the desired goals in order to make urban housing development acceptable for both men and women.
Development and validation of comprehensive closed formulas for atmospheric delay and altimetry correction in ground-based GNSS-R
Authors: Nikolaidou Thalia , Santos Marcelo , Williams Simon , Geremia-Nievinski Felipe
Published: May 2021

Radio wave propagation involved in Global Navigation Satellite System Reflectometry (GNSS-R) is subject to atmospheric refraction. Even for ground-based tracking stations, in applications such as coastal sea-level altimetry, the interferometric or reflection-minus-direct effect might be significant. Although atmospheric propagation delays are best investigated numerically via raytracing, including reflections, such a procedure is not trivial. We have developed simpler closed formulas to account for atmospheric refraction in ground-based GNSS-R, validated against independent raytracing. We provide specific expressions for the two components of the atmospheric interferometric delay and corresponding altimetry correction components, parameterized in terms of refractivity and bending angle. Assessment results showed excellent agreement for both components. We define the interferometric slant factor used to map interferometric zenithal delays to individual satellites.

Information-theoretic View of the Variation of the Gravitational Constant
Authors: Kak Subhash
Published: May 2021

Many recent theories speak of the spatial and temporal variations of the fundamental “constants”, and experiments have been performed to determine the variation. It has also been proposed that the variation of these constants is related to the strength of the gravitational potential whose changes, therefore, assume special significance. Here we examine potential change in G from the information-theoretic perspective of noninteger dimensionality and determine a relationship with respect to time. We show that the rate of change using this method is of the same order as estimated using other approaches.

Tempo e capital
Authors: Medina Cíntia , Parra Adriano
Published: May 2021

For millennia, humanity has been wondering about the nature of time. From the most remote civilizations until nowadays, time has been the object of curious fascination and contemplation. However, its social existence, despite its intangibility, is increasingly present in our days. Meet deadlines, time tasks, delimit durations; daily life progressively demands an acceleration of the activities we perform, combined with the rationalization and fragmentation of becoming itself. Several contemporary authors like Elias have devoted themselves to investigating their social nature. However, they conceived it, in the abstract sense, as a symbolic convention for measuring and ordering events, disregarding the processes that lead it to assume its character of domination within bourgeois society. Thus, this article seeks an ontological rescue of time in view of the role it plays in the capitalist mode of production, whose current neoliberal context subjugates us to the uninterrupted labor rhythms of accumulation.

In the Miscellaneous Section, the published articles cover various themes and reflections on different social phenomena in the Human Sciences, containing the following contributions: a) “A critique of the emancipatory ideological character of the solidarity economy policy implemented by the Brazilian government (2002-2013)” , by Douglas Santos (UNESP) and Ivan Campos (UEL); and b) “Notes on Humor and Borders”, by Lucas Woltmann Figueiró (UFRGS). Finally, we have the Review by Emilayne Souto (UFPB), with an analysis of the book by Thiago Aparecido Trindade: “Protest and Democracy: Urban Occupations and the Fight for the Right to the City”. 1.ed. Jundiaí, São Paulo: Paco, 2017. 300 p. ISBN: 978-85-462-0840-1.
Uma crítica ao caráter ideológico emancipatório da política de economia solidária implementada pelo Governo Brasileiro (2002-2013)
Authors: Godoy Douglas Fernando dos Santos , Campos Ivan Ferreira de
Published: May 2021

This article aimed to analyze the emancipatory ideological character of the Solidarity Economy policy adopted in Brazil between 2002 and 2013 in the light of the concept of social emancipation from a "Marxian" perspective. This study, which is qualitative, was based on the methodological contributions of Godoi, Bandeira-de-Mello e Silva (2006). Initially, classical articles dealing with the concept of emancipation were consulted, such as those by Marx, Engels and Gramsci. Then, it focused on contemporary articles on Solidarity Economy, such as those by Singer, Santos and Barbosa. It was possible to conclude that there is a significant gap between the emancipation proposals outlined by Marx and those that support Solidarity Economy in current standards. This conclusion reveals an ideological change in the movement, which has gone from being independent to allying itself with the State, thus contributing to overcoming problems generated by capitalism, such as unemployment and social inequality and, consequently, to the continuity of the capital system.
A etiologia da materialidade na teoria discursiva de Michel Foucault
Authors: Freixo Estêvão Carvalho
Published: May 2021

The field of discourse analysis, especially the segment that developed in France from the foundational works of Foucault and Pêcheux, has been concerned, since the results achieved by these two authors, with the important question of the implications of materiality in discourse. In this work, we recover certain positions in the domain of science and philosophy from which some theoretical turns responsible for important changes in this regard unfolded. Our analysis indicates that the concept of matter came to offer itself, from the 18th century onwards, as a new center of reference in a context in which it was necessary to undertake a long and hard battle against the primacy of consciousness, refusing, since then, to thinking substance as a starting point for scientific analysis. What seems worthy of note, however, is that important features of metaphysical reason have been somehow preserved – in different degrees and forms – in the cases we consider here.

Özgürlüğün Çekiciliği: Türkiye’ye Yönelen Dış Turizm Talebine Hak ve Özgürlüklerin Etkisi
Authors: DURA Yahya Can , KILIÇ Esin
Published: May 2021

Yüksek iktisadi potansiyele sahip bir sektör olarak turizm, özellikle gelişmekte olan ülkeler için ekonomik sorunlarla mücadelede önemli aksiyon araçlarındandır. Fakat bu sektör aynı zamanda oldukça kırılgan, iç ve dış etkilere açık ve çok aktörlü bir faaliyet alanıdır. Bu yönüyle bir toplumdaki özgürlüklerin boyutu ve durumu, özellikle turistlerin algılarını ve tercihlerini etkileme potansiyeline sahip olmakta ve turizm gelirleri ile turist sayısı üzerinde uzun dönemde bir etki yaratabilmektedir. Bu çalışmada, Türkiye ekonomisinin 1995-2018 döneminde özgürlüklerin, turizm sektörü için iki önemli değişken olan dış turizm geliri ve turist sayısı üzerindeki kısa/uzun dönem etkileri ARDL sınır testi yaklaşımı yardımıyla ortaya konulmaya çalışılmıştır. Ulaşılan sonuçlar, analize konu dönem için Türkiye’de bireysel ve politik özgürlüklerin turizm gelirleri ve turist sayısı açısından belirleyici göstergeler olduğu yönündedir.
İki Özgürlük Anlayışı ve Thomas Hill Green’in Pozitif Özgürlüğe Etkisi

Published: May 2021

İki özgürlük anlayışı, siyaset felsefesinin modern özgürlük teorisindeki en önemli tartışma alanlarından birisidir. Bu, onun hem aydınlanmadan gelen hem de ideolojik boyutları olan özelliklerinin bir sonucudur. Liberal özgürlük teorisinde güncelliğini koruyan bir konu olarak negatif ve pozitif özgürlük kavramları, liberalizmin sistemli bir ideoloji olduğu günden bu yana önemini korumayı başarmıştır. Elbette, bu modern dikotomisine erişene kadar özgürlük, pek çok farklı vecheden geçmiştir. Bu süreçlerde özgürlük, siyasal tecrübeler ve siyasal sistemlerle yakın ilişki içerisinde anlamlandırılmıştır. Bu noktada negatif özgürlük tecrübî siyasal süreçlerden kaynaklanan devlet-birey çelişkisi içerisinde gelişmiş bir karakteri inşa ederken, pozitif özgürlük bireyin içsel gelişimi ve rasyonel yeterliliğini arayan aydınlanmacı bir karakteri ortaya koymuştur. Bu kapsamda özgürlüğün modern bir ayrım olan iki özgürlük anlayışına ulaşana kadar geçen süreçteki tarihsel gelişimini betimleyerek onun düşünsel altyapısını ortaya koymak önemlidir. Liberal teoride zorunlu bir karşıtlığı içermeyen bu iki özgürlük fikri İngiliz filozof Thomas Hill Green’in pozitif özgürlüğe ortodoks anlamının dışında devletli bir özgürlük ekseni kazandırmasıyla başka bir düzleme taşınmıştır.

Construction activities entail substantial disturbance of topsoil and vegetative cover. As a result, stormwater runoff and erosion rates are increased significantly. If the soil erosion and subsequently generated sediment are not contained within the site, they would have a negative off-site impact as well as a detrimental influence on the receiving water body. In this study, replicable large-scale tests were used to analyze the ability of products to prevent sediment from exiting the perimeter of a site via sheet flow. The goal of these tests was to compare products to examine how well they retain sediment and how much ponding occurs upstream, as well as other criteria of interest to the Illinois Department of Transportation. The products analyzed were silt fence, woven monofilament geotextile, Filtrexx Siltsoxx, ERTEC ProWattle, triangular silt dike, sediment log, coconut coir log, Siltworm, GeoRidge, straw wattles, and Terra-Tube. Joint tests and vegetated buffer strip tests were also conducted. The duration of each test was 30 minutes, and 116 pounds of clay-loam soil were mixed with water in a 300 gallon tank. The solution was continuously mixed throughout the test. The sediment-water slurry was uniformly discharged over an 8 ft by 20 ft impervious 3:1 slope. The bottom of the slope had a permeable zone (8 ft by 8 ft) constructed from the same soil used in the mixing. The product was installed near the center of this zone. Water samples were collected at 5 minute intervals upstream and downstream of the product. These samples were analyzed for total sediment concentration to determine the effectiveness of each product. The performance of each product was evaluated in terms of sediment removal, ponding, ease of installation, and sustainability.
Optimized Mobile Edge Computing Framework for IoT based Medical Sensor Network Nodes
Authors: S. Raj Jennifer
Published: May 2021

Edge computing is a new computing paradigm that is rapidly emerging in various fields. Task completion is performed by various edge devices with distributed cloud computing in several conventional applications. Resource limitation, transmission efficiency, functionality and other edge network based circumstantial factors make this system more complex when compared to cloud computing. During cooperation between the edge devices, an instability occurs that cannot be ignored. The edge cooperative network is optimized with a novel framework proposed in this paper. This helps in improving the efficiency of edge computing tasks. The cooperation evaluation metrics are defined in the initial stage. Further, the performance of specific tasks are improved by optimizing the edge network cooperation. Real datasets obtained from elderly people and their wearable sensors is used for demonstrating the performance of the proposed framework. The extensive experimentation also helps in validating the efficiency of the proposed optimization algorithm.
U.S. Race Relations and Foreign Policy

It is easy for Americans to think that the world’s most egregious human rights abuses happen in other countries. In reality, our history is plagued by injustices, and our present reality is still stained by racism and inequality. While the Michigan Journal of International Law usually publishes only pieces with a global focus, we felt it prudent in these critically important times not to shy away from the problems facing our own country. We must understand our own history before we can strive to form a better union, whether the union be the United States or the United Nations. Ambassador Susan Page is an American diplomat who has faced human rights crises both at home and abroad. We found her following call to action inspiring. We hope you do too.
Country Risk

Published: May 2021

We construct new measures of country risk and sentiment as perceived by global investors and executives using textual analysis of the quarterly earnings calls of publicly listed firms around the world. Our quarterly measures cover 45 countries from 2002-2020. We use our measures to provide a novel characterization of country risk and to provide a harmonized definition of crises. We demonstrate that elevated perceptions of a country's riskiness are associated with significant falls in local asset prices and capital outflows, even after global financial conditions are controlled for. Increases in country risk are associated with reductions in firm-level investment and employment. We also show direct evidence of a novel type of contagion, where foreign risk is transmitted across borders through firm-level exposures. Exposed firms suffer falling market valuations and significantly retrench their hiring and investment in response to crises abroad. Finally, we provide direct evidence that heterogeneous currency loadings on global risk help explain the cross-country pattern of interest rates and currency risk premia.
