20. yüzyılın son çeyreğinden itibaren
kitle iletişimi, ulaşım ve üretim alanlarında görülen teknolojik gelişmeler,
insanoğlunun refahının artmasını sağlayan bir ortam oluşturmakla birlikte nüfusun
aşırı artışı üretimin boyutlarını değiştirmiş dolayısı ile üretim sonucu oluşan
zararlı atıklar kirlilik etkisi oluşturmuştur. Bu etki özellikle son yıllarda
dünyanın ekolojik dengesini bozacak boyutlara ulaşmıştır. Dolayısıyla işletmeler
çevresel faktörlere dikkat ederek üretimlerini devam ettirirken normal üretim
maliyetleri ile birlikte çevre odaklı önleme kullanma ve zarar gibi birtakım ek
maliyetlere de katlanmaları gerekmektedir. Konunun önemi gereği çevresel
maliyetlerin işletme düzeyinde tekdüzen muhasebe sistemine entegrasyonu ile
ilgili çalışmalar son dönemlerde literatüre yeni girmeye başlamıştır. Özellikle
tekdüzen muhasebe sisteminde çevre maliyetlerinin muhasebe sistemi içinde nasıl
yer alacağı, nasıl sınıflanacağı, üretim maliyetlerine nasıl yükleneceği
hususları araştırmacılar ve uygulamacılar için önem arz etmektedir. Bu çalışmada çevre maliyetleri kısaca
tanıtılarak çevre maliyetlerinin muhasebe sisteminde nasıl yer alması gerektiği
ve nasıl muhasebeleştirildiği anlatılmıştır. Çalışmanın uygulaması, kurşun,
sülfürik asit ve plastik gibi çevre kirliliği unsurlarını yoğun olarak içeren
bir sektör olan akümülatör sektöründen TO-RO-NA Endüstri Limited Şirketi’nde
yapılmıştır. İşletmede çevre maliyetleriyle ilgili bir tasnif işlemi yapılarak
işletmenin gerçek değerleri ile çevre maliyetleri muhasebeleştirilmiştir. Genel
üretim giderleri dağıtılırken çevre gider yeri açılması ile dağıtımlar tamamlandığında
işletmenin genel üretim giderleri kapsamında ne kadar çevresel maliyete
katlandığı tespit edilmiş olur. Genel üretim giderleri, dağıtım öncesi genel

Due to the emergence of the self in foreign/second language (L2) motivation theory and research following the introduction of the L2 Motivational Self System (L2MSS) (Dörnyei, 2005, 2009), the past decade has witnessed a surge of attention devoted to the two self dimensions: the Ideal L2 Self, and the Ought-to L2 self of the model (Boo, Dörnyei, & Ryan, 2015). The third core component, however, the L2 Learning Experience has become undeservedly marginalized. We think that such relative neglect has been brought about by two phenomena. On the one hand, the L2 Learning Experience, has so far been underconceptualized, and, as such, its intangible, amorphous nature has undermined its applicability in research on a similar scale that a more elaborate theorization of the other two future self-guides has enabled. On the other hand, by incorporating Markus and Nurius’ (1986) possible selves theory into L2 motivation research, Dörnyei was able to import adaptable and novel concepts to the field, which set the course of the research agenda for years to come.
A study of retrospective and concurrent foreign language learning experiences: A comparative interview study in Hungary
Authors: Csizér Kata , Kálmán Csaba
Published: March 2019

Despite the fact that the influence of learning experiences on foreign language learning motivation has been widely acknowledged and emphasised, there are hardly any studies concentrating on these learning experiences. Hence, the aim of this study is to map the language learning experiences of former and current language learners in order to provide a detailed account of the possible components of the foreign language learning experience. Data were collected with the help of a qualitative interview schedule involving 22 language learners in two subsamples. Ten participants are English language teachers as former foreign language learners, while 12 students, current learners of English, have also been recruited. The most important result of our study is that foreign language learning experience seems to be a complex construct including immediate and present aspects as well as self-related components and attributions. Language learning success, the teacher’s personality, contact experiences, as well as attitudes towards the L2 seem to stand out as important components for both groups of learners. Apart from discussing the differences and similarities between retrospective and concurrent experiences, we will provide pedagogical and research-related implications as well.
Reframing the L2 learning experience as narrative reconstructions of classroom learning

Published: March 2019

In this study we investigate the situated and dynamic nature of the L2 learning experience through a newly-purposed instrument called the Language Learning Story Interview, adapted from McAdams’ life story interview (2007). Using critical case sampling, data were collected from an equal number of learners of various L2s (e.g., Arabic, English, Mandarin, Spanish) and analyzed using qualitative comparative analysis (Rihoux & Ragin, 2009). Through our data analysis, we demonstrate how language learners construct overarching narratives of the L2 learning experience and what the characteristic features and components that make up these narratives are. Our results provide evidence for prototypical nuclear scenes (McAdams et al., 2004) as well as core specifications and parameters of learners’ narrative accounts of the L2 learning experience. We discuss how these shape motivation and language learning behavior.
Snapshot semantics for temporal multiset relations
Authors: Dignös Anton , Glavic Boris , Niu Xing , Böhlen Michael , Gamper Johann
Published: March 2019

Snapshot semantics
is widely used for evaluating queries over temporal data: temporal relations are seen as sequences of snapshot relations, and queries are evaluated at each snapshot. In this work, we demonstrate that current approaches for snapshot semantics over interval-timestamped multiset relations are subject to two bugs regarding snapshot aggregation and bag difference. We introduce a novel temporal data model based on
K
-relations that overcomes these bugs and prove it to correctly encode snapshot semantics. Furthermore, we present an efficient implementation of our model as a database middleware and demonstrate experimentally that our approach is competitive with native implementations.

Entity resolution (ER) is the problem of accurately identifying multiple, differing, and possibly contradicting representations of unique real-world entities in data. It is a challenging and fundamental task in data cleansing and data integration. In this work, we propose graph differential dependencies (GDDs) as an extension of the recently developed graph entity dependencies (which are formal constraints for graph data) to enable approximate matching of values. Furthermore, we investigate a special discovery of GDDs for ER by designing an algorithm for generating a non-redundant set of GDDs in labelled data. Then, we develop an effective ER technique, Certus, that employs the learned GDDs for improving the accuracy of ER results. We perform extensive empirical evaluation of our proposals on five real-world ER benchmark datasets and a proprietary database to test their effectiveness and efficiency. The results from the experiments show the discovery algorithm and Certus are efficient; and more importantly, GDDs significantly improve the precision of ER without considerable trade-off of recall.
Scaling-up in-memory datalog processing

Published: March 2019

Recursive query processing has experienced a recent resurgence, as a result of its use in many modern application domains, including data integration, graph analytics, security, program analysis, networking and decision making. Due to the large volumes of data being processed, several research efforts across multiple communities have explored how to scale up recursive queries, typically expressed in Datalog. Our experience with these tools indicate that their performance does not translate across domains---e.g., a tool designed for large-scale graph analytics does not exhibit the same performance on program-analysis tasks, and vice versa.

Starting from the above observation, we make the following two contributions. First, we perform a detailed experimental evaluation comparing a number of state-of-the-art Datalog systems on a wide spectrum of graph analytics and program-analysis tasks, and summarize the pros and cons of existing techniques. Second, we design and implement our own general-purpose Datalog engine, called RecStep, on top of a parallel single-node relational system. We outline the techniques we applied on RecStep, as well as the contribution of each technique to the overall performance. Using RecStep as a baseline, we demonstrate that it generally out-performs state-of-the-art parallel Datalog engines on complex and large-scale Datalog evaluation, by a 4-6X margin. An additional insight from our work is that it is possible to build a high-performance Datalog system on top of a relational engine, an idea that has been dismissed in past work.
Endometriosis and the menopause: why the question merits our full attention

Published: March 2019

As an estrogen-dependent disease, endometriosis was thought to become less active or regress with the onset of the menopause. However, based on some new data, we are discovering that this pathology can emerge or reappear at this period of life. Clinicians must consider it as a possible cause for cases of pelvic pain, and heavy bleeding. Authors have described a possibility of transformation of the intraperitoneal proliferation into a malignant type with ovarian, bowel and even lung metastasis. The risk of transformation into an ovarian cancer is around 2 or 3%. The role of menopausal hormonal therapy will be discussed as in recurrence in the case of residue existence, especially after incomplete surgery. Is it possible to prescribe hormonal therapy to a menopausal women suffering climacteric symptoms as it could trigger a recurrence of endometriosis and even an increased risk of malignant degeneration? This remains unclear. It is an unresolved therapeutic dilemma; the choice between surgery or medical treatment?

Ionic liquid-based nanofluids (ionanofluids) for thermal applications: an experimental thermophysical characterization
Authors: Oster Kamil , Hardacre Christopher , Jacquemin Johan , Ribeiro Ana P. C. , Elsinawi Abdulaziz
Published: March 2019

Heat transfer fluids materials are manufactured for the purpose of transfer, distribution and storage of heat. Several of their important properties can be listed (for example flash point, thermal expansivity or technical safety). However, to assess the thermal exchange performance of these fluids, a prior knowledge of their heat capacity, density, viscosity and thermal conductivity is obligatory. The most popular heat transfer fluids are based on organic liquids, such as ethylene glycol. However, new technologies and development require more efficient materials. Ionanofluids, mixtures of ionic liquids and nanoparticles, were proposed as a viable replacement for those commonly used fluids due to the properties of ionic liquids (wide liquid range or low vapour pressure and flammability) combined with enhanced thermophysical properties of nanofluids caused by the dispersion of nanoparticles (mainly thermal conductivity and heat capacity). Very few authors reported the extensive analysis of those systems thermophysical properties and impact on the heat exchange efficiency. Moreover, the availability of published data is very limited. The aim of this work is to investigate ionanofluids based on the trihexyl(tetradecyl)phosphonium cation paired with the acetate, butanoate, hexanoate, octanoate or decanoate anion, mixed with carbon nanotubes, boron nitride, graphite or mesoporous carbon as nanoparticles with concentration up to 3 wt %. The density, heat capacity, thermal stability, thermal conductivity and viscosity of selected ionanofluids were determined experimentally as functions of the temperature (up to 363.15 K) and compared with theoretical tools to evaluate the predictive capability. Based on the experimental results, lubrication, heat storage potential and economic analysis were also discussed and compared to commercial heat transfer fluids.
Preparation, characterization and kinetics study of chitosan/PVA electrospun nanofiber membranes for the adsorption of dye from water
Authors: Mei Yang , Runjun Sun , Yan Feng , Honghong Wang , Hao Dou , Chengkun Liu
Published: March 2019

In this study, chitosan (CS) nanofibers with two different degrees of deacetylation (DDA) were first successfully fabricated from its solution in 1% aqueous acetic acid solution by mixing with poly(vinyl alcohol) (PVA) solution at a weight ratio of 50/50 via the electrospinning method. Then, the CS/PVA membranes were further modified by glutaraldehyde vapor. The prepared nanofibers were characterized by field electron scanning electron microscopy (FESEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), the tensile test, the contact angle test, the weight loss test and the adsorption test for Congo red (CR). SEM analysis showed defect-free nanofibers and a uniform diameter distribution, with an average diameter of 100–125 nm. Subsequently, FTIR spectroscopy, XRD and TGA indicated that the modified CS/PVA membranes had a relatively higher thermal stability, because the thermal decomposition temperature of the unmodified CS/PVA membranes (~250°C) increased to a higher temperature (~ 300°C) for the modified CS/PVA. The nanofiber membranes after modification possessed better mechanical tensile properties. The membranes with lower DDA had a relatively higher tensile strength, which can withstand the maximum tensile strength of up to 6.36 MPa. Furthermore, the resulting membranes showed excellent hydrophilicity and kept their stability in distilled water, acidic, and basic media for 20 days. In the adsorption study, the maximum adsorption capacity of the membrane for CR was 358 mg/l in the optimum operating conditions of 25°C, pH = 6, 0.3 g membrane and 50 ml of 100 mg/l CR solutions. The resulting nanofibers membranes showed a better fitting to the Langmuir isotherm model and pseudo-second-order kinetic model.

American legal realism numbers among the most important theoretical contributions of legal academia to date. Given the movement’s influence, as well as the common centrality of certain key figures, it is surprising that privacy scholarship in the United States has paid next to no attention to the movement. This inattention is unfortunate for several reasons, including that privacy law furnishes rich examples of the indeterminacy thesis — a key concept of American legal realism — and because the interdisciplinary efforts of privacy scholars to explore extra-legal influences on privacy law arguably further the plot of legal realism itself.
Turning Privacy Inside Out
Authors: Cohen Julie E.
Published: March 2019

The problem of theorizing privacy moves on two levels, the first consisting of an inadequate conceptual vocabulary and the second consisting of an inadequate institutional grammar. Privacy rights are supposed to protect individual subjects, and so conventional ways of understanding privacy are subject-centered, but subject-centered approaches to theorizing privacy also wrestle with deeply embedded contradictions. And privacy’s most enduring institutional failure modes flow from its insistence on placing the individual and individualized control at the center. Strategies for rescuing privacy from irrelevance involve inverting both established ways of talking about privacy rights and established conventions for designing institutions to protect them. In terms of theory, turning privacy inside out entails focusing on the conditions that are needed to produce sufficiently private and privacy-valuing subjects. Institutionally, turning privacy inside out entails focusing on the design, production, and operational practices most likely to instantiate and preserve those conditions.
Contextual Integrity Up and Down the Data Food Chain
Authors: Nissenbaum Helen
Published: March 2019

According to the theory of contextual integrity (CI), privacy norms prescribe information flows with reference to five parameters — sender, recipient, subject, information type, and transmission principle. Because privacy is grasped contextually (e.g., health, education, civic life, etc.), the values of these parameters range over contextually meaningful ontologies — of information types (or topics) and actors (subjects, senders, and recipients), in contextually defined capacities. As an alternative to predominant approaches to privacy, which were ineffective against novel information practices enabled by IT, CI was able both to pinpoint sources of disruption and provide grounds for either accepting or rejecting them. Mounting challenges from a burgeoning array of networked, sensor-enabled devices (IoT) and data-ravenous machine learning systems, similar in form though magnified in scope, call for renewed attention to theory. This Article introduces the metaphor of a data (food) chain to capture the nature of these challenges. With motion up the chain, where data of higher order is inferred from lower-order data, the crucial question is whether privacy norms governing lower-order data are sufficient for the inferred higher-order data. While CI has a response to this question, a greater challenge comes from data primitives, such as digital impulses of mouse clicks, motion detectors, and bare GPS coordinates, because they appear to have no meaning. Absent a semantics, they escape CI’s privacy norms entirely.
The Right to Communications Confidentiality in Europe: Protecting Privacy, Freedom of Expression, and Trust
Authors: Zuiderveen Borgesius Frederik J. , Steenbruggen Wilfred
Published: March 2019

In the European Union, the General Data Protection Regulation (GDPR) provides comprehensive rules for the processing of personal data. In addition, the EU lawmaker intends to adopt specific rules to protect confidentiality of communications, in a separate ePrivacy Regulation. Some have argued that there is no need for such additional rules for communications confidentiality.

This Article discusses the protection of the right to confidentiality of communications in Europe. We look at the right’s origins to assess the rationale for protecting it. We also analyze how the right is currently protected under the European Convention on Human Rights and under EU law.

We show that at its core the right to communications confidentiality protects three individual and collective values: privacy, freedom of expression, and trust in communication services. The right aims to ensure that individuals and organizations can safely entrust communication to service providers. Initially, the right protected only postal letters, but it has gradually developed into a strong safeguard for the protection of confidentiality of communications, regardless of the technology used.

Hence, the right does not merely serve individual privacy interests, but also other more collective interests that are crucial for the functioning of our information society. We conclude that separate EU rules to protect communications confidentiality, next to the GDPR, are justified and necessary.
Development and Evaluation of a Post–Hip Fracture Instructional Workshop for Caregivers
Authors: Ariza-Vega Patrocinio , Ortiz-Piña Mariana , Mora-Traverso Marta , Martín-Martín Lydia , Salazar-Graván Susana , Ashe Maureen C.
Published: March 2019

Background and Purpose:

A hip fracture is an unexpected traumatic event. Caregivers of patients with an acute hip fracture have only short time to learn the new skills of postoperative care and handling of the patient. This sudden responsibility changes the life of the caregivers who perceive a higher level of preoccupation about the care of their family member/friend. The objective of this study was to develop and test feasibility for a post–hip fracture inpatient instructional workshop for caregivers of older adults with hip fracture and to establish their knowledge of hip fracture recovery and perceptions of the utility and satisfaction with the workshop.

Methods:

This 2-part study was conducted at the University Hospital of Granada, Spain, from September 2016 to April 2017. We invited caregivers of patients (60 years of age or older) hospitalized for a surgically treated fall-related hip fracture to attend an informational and skill development hospital-based workshop (60-90 minutes in duration) on postdischarge management strategies. Following the workshop, we invited caregivers to complete a questionnaire to obtain their knowledge about care after hip fracture and their perceived concerns. Furthermore, we requested that they provide feedback on workshop utility and satisfaction (0-10 points) and suggestions for improving the workshop.

Results and Discussion:

We delivered 42 workshops over an 8 month period. One hundred three caregivers attended the sessions and enrolled in the study, mean (SD) age: 52.1 (12.8) years. Sixty-nine percent of the caregivers were women. Caregivers' main concern was apprehension for delivering physical care to their family member/friend (75%), followed by lack of time (42%). Caregivers who were employed were 3.16 times as likely to be concerned about time availability to provide care for their family member/friend. The median (Q1, Q3) of both workshop utility and satisfaction was 10 (10, 10), minimum-maximum: 7 to 10.

Conclusions:

Caregivers in this study stated that the workshop was useful and satisfactory. Because caregivers play such a vital role in recovery after hip fracture, providing knowledge and skill development as part of health care delivery may support more person-centered care.
Sex-Related Differences After a Single Bout of Maximal Eccentric Exercise in Response to Acute Effects: A Systematic Review and Meta-analysis

Morawetz, D, Blank, C, Koller, A, Arvandi, M, Siebert, U, and Schobersberger, W. Sex-related differences after a single bout of maximal eccentric exercise in response to acute effects: a systematic review and meta-analysis.J Strength Cond Res34(9): 2697–2707, 2020—The most prominent effects after unaccustomed eccentric exercise are muscle damage, muscle soreness, strength loss, and higher concentrations of muscle proteins in the plasma. The aim of this systematic review is to evaluate sex-related differences in these acute effects. A systematic literature search in MEDLINE following the PRISMA guidelines was performed. Inclusion criteria were the difference in absolute outcomes between sexes in eccentric muscle strength, strength loss after eccentric exercise, blood concentrations of creatine kinase (CK), and delayed onset muscle soreness (DOMS). Results for maximal eccentric torque and CK data were pooled using a random-effect meta-analysis. A meta-regression was conducted to explain heterogeneity. Based on the 23 included trials, men showed significantly higher absolute eccentric strength. No sex-related differences were detected when normalizing strength for body mass, cross-sectional area of the muscle, or fat-free mass. Women displayed a tendency toward greater relative strength loss immediately after exercise. The absolute CK concentrations of men were significantly higher after exercise-induced muscle damage. No significant difference was found between sexes in DOMS. Untrained men and women display similar responses in all measures of relative muscle strength and DOMS. Apart from the enzymatic activity after exercise and the levels of absolute eccentric torque, there is no evidence for sex-related differences immediately after eccentric exercise. Therefore, eccentric training might have the same impact on men and women. One potential sex difference with practical relevance would be the possible difference in fatigue pattern immediately after eccentric exercise.

J Strength Cond Res 35(8): 2158–2164, 2021—How important leg or trunk muscles are for balance and sprint performance is still unexplored. Therefore, we separately fatigued the leg and trunk musculature and examined their contribution to strength, balance, sprint, and agility performance. Twenty-four healthy adults (12 women; age 22.9 [SD: 2.6] years; body mass 59 [10] kg; height 1.65 [0.09] m; and 12 men; age 22.7 [3.0] years; body mass 78 [9] kg; height 1.81 [0.06] m; at least 3 training sessions/week for at least 90 minutes) underwent a leg and a trunk fatigue procedure, each of 20-minute duration and a control condition at rest in a randomized order. Each condition was conducted individually on 3 separate days. Isokinetic leg and trunk strength, as well as static and dynamic balance, sprint, agility, and prone plank endurance, were assessed before and after each fatiguing protocol. Before assessment, a familiarization was conducted. Pairwise magnitude-based inference analyses showed likely relevant deterioration in leg (probability >87%; 0.36 < standardized mean differences [SMDs] < 0.92) and trunk (>88%, 0.28 < SMD < 0.74) fatigue procedures for all motor test parameters compared with the control condition, except for the 20-m sprint after the trunk fatigue procedure. Isokinetic strength testing revealed a large loss of strength in leg fatigue (particularly knee extension, 78%, SMD = 0.24) and trunk fatigue (trunk flexion, 100%, SMD = 1.36). Acute fatigue of leg and trunk muscles decreases performance in relevant measures of strength, balance, sprint, and agility. The impact of leg fatigue compared with trunk fatigue was larger in almost all measurements.

Effects of transcranial direct current stimulation with caffeine intake on muscular strength and perceived exertion. J Strength Cond Res 33(5): 1237–1243, 2019—The aim of this study was to investigate the acute effects of transcranial direct current stimulation (tDCS) associated with caffeine intake on muscular strength and ratings of perceived exertion (RPE). Fifteen healthy young males recreationally trained (age: 25.3 ± 3.2 years, body mass: 78.0 ± 6.9 kg, height: 174.1 ± 6.1 cm) were recruited. The experimental conditions started with the administration of caffeine (Caff) or placebo (Pla) 1 hour before starting the anodal tDCS (a-tDCS or sham). There was an intake of 5 mg·kg−1 of Caff or 5 mg·kg−1 of Pla. After the intake, a-tDCS or sham was applied in the left dorsolateral prefrontal cortex with intensity of 2 mA and 20 minutes of duration. The experimental conditions were defined as Sham + Pla, a-tDCS + Pla, Sham + Caff, and a-tDCS + Caff. After the conditions, muscular strength and RPE were verified. Muscular strength was determined by volume load performed in bench press exercise. Muscular strength in Sham + Pla condition was lower compared with all others conditions (p < 0.05). The RPE in the Sham + Pla was greater compared with a-tDCS + Caff (p < 0.05). Muscular strength was greater in all experimental conditions, and a-tDCS + Caff had lower RPE compared with placebo. When very little gains in muscle strength are expected, both caffeine and tDCS were effective in increasing muscle strength. Besides, the improvement in RPE of the caffeine associated with a-tDCS could prove advantageous in participants experienced in strength training. In fact, coaches and applied sport scientists quantitating the intensity of training based on RPE.

Bayliff, GE, Jacobson, BH, Moghaddam, M, and Estrada, C. Global positioning system monitoring of selected physical demands of NCAA Division I football players during games. J Strength Cond Res 33(5): 1185–1191, 2019—Global positioning system (GPS) tracking of athletes in selected sports is a new innovation into obtaining comprehensive data regarding physical output with respect to distance travelled (DT), acceleration, and change of direction. The purpose of this study was to determine selected physical demands of American football players during the course of games and to compare such data by player position. Offensive lineman (OL) (n = 14) and defensive lineman (DL) (n = 9) and offensive wide receivers (WRs) (n = 10) and defensive backs (DBs) (n = 10) were fitted with GPS monitors during games. Collected data included DT, maximum velocity (MV), and acceleration (AC), deceleration (DC) distance at 2 intensities. Results indicated that DBs travelled significantly (p < 0.05) greater distances than OL and WR, but not DL. For MV, DBs and WRs were not significantly different but were significantly different from OL and DL. Also, DL was significantly different than OL. For the most intense acceleration (3–10 m·s−2), WR accelerated significantly further than all other positions and DBs accelerated further than DL and OL. There was not significant difference between DL and OL. For deceleration at the high-intensity measure, significant differences existed among all positions. Underestimation of workload during games could be a factor for the overuse and soft-tissue injuries and more serious injuries. Furthermore, using GPS tracking of similar variables as found in this study may benefit coaches and trainers in many other high-intensity sports.

Eco-literacy (knowledge of natural history, and direct observation of the natural world and the organisms it contains) is critical to a holistic understanding of biology. Many undergraduate biology students lack this knowledge and experience, often because of a lack of engagement with the environmental science curriculum. The effectiveness of service learning is well established, but few examples of service-learning projects in the context of natural history education have been published. We describe how we used best practices for the development of a field-based service-learning project in a college-level natural history course. The project was built around established learning goals and was conducted through a partnership with a local state park. Students worked in groups to conduct bird biodiversity surveys and prepared a printed bird-watching guide, which was presented to park staff. The project was linked to a series of assignments intended to maximize academic and personal growth, including a project plan, progress report, and reflection paper. Students reported increased engagement in the course curriculum and an increased sense of the relevance of the course content.

O DIREITO FUNDAMENTAL À OBJEÇÃO DE CONSCIÊNCIA NAS ATIVIDADES DE ENSINO QUE UTILIZEM ANIMAIS
Authors: Rodrigues Maira Luciane Dos Santos , Rammê Rogério Santos
Published: March 2019

A pesquisa teve como objetivo o estudo do instituto da objeção de consciência quando invocado em face de atividades de ensino que utilizem animais. Definido seu conceito, o qual consiste na recusa do cumprimento de norma legal, caso essa norma viole as convicções morais do indivíduo, estabeleceu-se a distinção entre o primeiro instituto e a desobediência civil, que é o ato de desobedecer a lei com intuito de mudança política ou legal. Na legislação estão previstas expressamente duas hipóteses de cabimento, dentre as quais não consta hipótese no tocante às atividades de ensino que utilizem animais. Contudo a doutrina majoritária aduz a possibilidade do alargamento dessas hipóteses, uma vez tratar-se de rol exemplificativo. O estudo é qualitativo de revisão bibliográfica. A utilização de animais, conforme já exposto, é permitida pela legislação vigente, entretanto suscita análise de questões éticas e morais, inclusive, a dos animais. Observa-se que a questão ética e moral vem sendo utilizada como substrato para a oposição da objeção de consciência nesses casos. O estudo das decisões judiciais, nesse sentido, identificou parco acervo sobre o tema. Por fim, concluiu-se que o instituto, apesar de ter o condão de tutelar de forma efetiva a liberdade de consciência do indivíduo que objeta por razões morais e éticas o uso de animais em experimentos nas atividades de ensino, ainda carece de uma reflexão mais apurada por parte não só da sociedade, mas dos próprios julgadores, sob pena de relegar um direito fundamental que é pautado na dignidade do ser humano.
RACISMO: O SISTEMA DE COTAS SERIA UMA ALTERNATIVA DE INCLUSÃO SOCIAL VIÁVEL PARA A PROMOÇÃO DA IGUALDADE RACIAL EDUCACIONAL NO SISTEMA BRASILEIRO?
Authors: Ferenz Gabriela Martins , Petry Alexandre Torres
Published: March 2019

O presente trabalho discorre sobre o conhecimento relacionado ao racismo e seus sistemas de cotas raciais a fim de promover a igualdade racial educacional no sistema brasileiro como alternativa de inclusão social para impedir à prática de discriminação. A questão a ser analisada neste trabalho é se a adoção de cotas raciais seria, de fato, uma boa política para concretizar a integração do negro na sociedade de maneira igualitária. Apesar de tantos anos após a abolição da escravatura, a população negra ainda é tratada com preconceito e discriminação. Para compreendê-lo com mais profundidade, faz-se pertinente discorrer sobre ele com base em uma perspectiva histórica, ou seja, na história da humanidade. Como objetivos específicos da presente pesquisa têm-se demonstrar para que se possa promover a igualdade racial de educação no Brasil será necessário ser desenvolvido desde a educação infantil nas escolas e não apenas na fase universitária, padronizações educacionais de ensino no Brasil. Ao final, conclui-se que o preconceito racial ainda é uma triste realidade que precisa ser combatida, e, para que haja uma verdadeira igualdade entre pessoas de todas as raças, é necessário combater o preconceito e adotar ações que possibilitem que todos tenham acesso às mesmas oportunidades, sem sofrer discriminação racial ou qualquer outra. Sendo que a adoção de cotas sociais, embora uma opção mais abrangente que as cotas raciais, deve ser vista como uma alternativa de política temporária, já que é realmente necessário é que o governo cumpra a sua responsabilidade de oferecer uma educação de qualidade para todos os brasileiros.

Published: March 2019

O adicional de insalubridade tem como fundamento remoto o princípioda dignidade da pessoa humana, e visa compensar, mediante pagamento de pecúnia, os malefícios que algumas formas de trabalho causam à integridade física do trabalhador. O artigo trata sobre a problemática existente na nova legislação trabalhista, em especial, a área que contempla a insalubridade, bem como suas implicações. A proposta é obter uma visão geral e atual sobre o tema, quanto a sua implantação, efetividade, vantagens e desvantagens, por meio de análise crítica sobre a Reforma Trabalhista. O objeto de estudo visa, especificamente, analisar os dispositivos que tratam sobre o enquadramento do grau de insalubridade via Convenção Coletiva de Trabalho, a possibilidade de a gestante ou lactante trabalhar em local insalubre e o pagamento de honorários periciais pelo reclamante, mesmo sendo beneficiário da justiça gratuita. Nesse sentido,pode-se vislumbrar a importância do tema proposto, uma vez que se faz necessário um pensamento crítico e plural para que se atente a todos os lados e necessidades.

Authors: Priebe Leonardo da Costa Priebe Da Costa , Petry Alexandre Torres
Published: March 2019

A revolução tecnológica trouxe à ciência do Direito uma série de preocupações. Com o advento das denominadas tecnologias disruptivas, relevantes institutos jurídicos estão sendo progressivamente vulnerabilizados. Este artigo versa sobre a ascensão dos drones e seu potencial de violação ao direito de privacidade, consagrado pela Constituição Federal de 1988 como direito fundamental. Neste cenário, objetiva-se analisar a regulação existente no ordenamento jurídico brasileiro acerca da temática – dissertando, por conseguinte, sobre seus aspectos principais. De tal exame, pois, clarificam-se carências regulatórias essenciais ao resguardo do direito à privacidade, notadamente no que diz respeito ao registro e controle dosdrones, ao passo que outros pontos da legislação, a exemplo dos aspectos relacionados à segurança dos civis expostos às operações de voo, mostram-se suficientemente desenvolvidos.Palavras-chave: Drones. Privacidade. Direito

Published: March 2019

In November 2018, the U.S. Food and Drug Administration (FDA) approved brentuximab vedotin (BV) for the treatment of adult patients with previously untreated systemic anaplastic large cell lymphoma or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with cyclophosphamide, doxorubicin, and prednisone (CHP). Approval was based on ECHELON-2, a randomized, double-blind, actively controlled trial that compared BV+CHP with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in 452 patients with newly diagnosed, CD30-expressing PTCL. Efficacy was based on independent review facility-assessed progression-free survival (PFS). The median PFS was 48.2 months with BV+CHP versus 20.8 months with CHOP, resulting in a hazard ratio (HR) of 0.71 (95% confidence interval [CI]: 0.54–0.93). The trial also demonstrated improvement in overall survival (HR 0.66; 95% CI: 0.46–0.95), complete response rate (68% vs. 56%), and overall response rate (83% vs. 72%) with BV+CHP. The most common adverse reactions (incidence ≥20%) observed ≥2% more with BV+CHP were nausea, diarrhea, fatigue or asthenia, mucositis, pyrexia, vomiting, and anemia. Peripheral neuropathy rates were similar (52% with BV+CHP, 55% with CHOP). Through the Real-Time Oncology Review pilot program, which allows FDA early access to key data, FDA granted this approval less than 2 weeks after official submission of the application.
Reactive power and harmonic compensation: A case study for the coal-mining industry
Authors: Roos F. , Bansal R.C.
Published: March 2019

This study reports on a case study in Grootegeluk Mine: Exxaro Coal, Lephalale, South Africa, in terms of power factor correction (PFC), load flow, harmonic frequency scans and harmonic voltage distortion analyses. The DIgSilent PowerFactory software was used for network simulations. Harmonic and reactive power compensation techniques were compared in terms of filter type evolution and technology advancement, with the use of simple trade-off criteria such as cost-effectiveness versus performance. It was found that both passive and hybrid filters were more favourable and could effectively compensate all voltage and current harmonics and reactive power for large nonlinear loads. The installation of switched PFC filter banks tuned at the fifth harmonic order accommodates future network growth and this solution can be rolled out to any mining industry as a benchmark to lower energy cost and maximise savings achievable on the electricity bill.
New Dimensions of Functional Illiteracy in the Digital Economy
Authors: Baskakova Marina , Soboleva Irina
Published: March 2019

We explore the new aspects of functional illiteracy associated with the inability to seamlessly fit into the new economic reality that requires mastering skills and technologies adequate to the digital economy. Data on the level of com­puter literacy and web accessibility for different categories of population is used as basic indicators of readiness to use digital technology in everyday life and in the workplace. The study shows that about one third of the adult popu­lation in Russia is at risk of functional illiteracy. Older cohorts, low-educated people from low-income households, and rural dwellers are the most vulne­rable groups. The regional factor makes an additional contribution to the digi­tal divide. We argue that special measures and programs to overcome digital illiteracy targeted at population groups in high-risk geographic areas should be developed. The article is based on the data from the Integrated Household Living Conditions Survey conducted by Rosstat and the Federal Statistical Sur­vey on the Use of Information Technology.

Authors: Shcheglova Irina , Koreshnikova Yulia , Parshina Olga
Published: March 2019

This study explores how academic, research and extracurricular engagement is linked to the development of critical thinking in undergraduates using a spe­cific statistical model. Empirical basis of research was provided by the results of the Student Experience in the Research University (SERU) survey conduc­ted in one of Russian national research universities in 2017 (N = 3,344). Binary logistic regression reveals a statistically significant relationship between the development of critical thinking and student engagement in learning, research and extracurricular activities, higher involvement corresponding to better cri­tical thinking skills. The findings may be useful for developing curricula, allo­cating student workload, and devising new initiatives for university students.
