The first Nearctic record of the genus Neocheiridium (Pseudoscorpiones: Cheiridiidae), with description of Neocheiridium gullahorum sp. n.
Authors: Sammet Kaarel , Kurina Olavi , Klompen Hans
Published: January 2020

The genus Neocheiridium Beier, 1932 currently contains seven Neotropical (including Caribbean) and two Afrotropical species, with no Nearctic records.

An undescribed species of Neocheiridium from South Carolina was discovered in the Ohio State University Acarology Collection and is described as Neocheiridium gullahorum, n. sp. (based on specimens of both sexes). A key to known world species of Neocheiridium is proposed.
Automation Now and Then: Automation Fevers, Anxieties and Utopias
Authors: Bassett Caroline , Roberts Ben
Published: January 2020

This article discusses the cyclical nature of automation anxiety and examines ways of thinking about the recurrence of automation debates in culture, particularly with reference to the 1950s, 1960s and today. It draws on the concept of topos, developed by Erkki Huhtamo, to explore the
return of automation anxieties (and fevers) and the relationship between material formations and technological imaginaries. We focus in particular on recent left thinking where automation is used to invoke a postcapitalist utopia. Examples include Nick Srnicek and Alex Williams's Inventing
the Future: Postcapitalism and a World Without Work (2015) and Aaron Bastani's Fully Automated Luxury Communism: A Manifesto (2018). This strand of contemporary thinking is re-framed through our return to early automation scares emerging in the late 1960s. We explore engagements
between labour, civil rights, left public intellectuals, and emerging industrial figures, over questions of automation and work. We pay particular attention to questions of 'who benefits and when?' These are germane to the question of utopian futures or non-reformist reformism as it recurs
today. What interests us here is the concept of revived salience: not only how the tropes evident in these debates are revived and re-embedded today, but how do they find their force, and what do they imply.
Nomic Sound
Authors: Deane Cormac
Published: January 2020

This article pays attention to the media channels through which different modes of power flow, and specifically to how they sound. The soundscapes of real and fictional control rooms provide a way of understanding the connection between automation, decision-making and politics. The
types of sounds that accompany control rooms screens map onto alternative, at times contradictory, interpretations of the ontological status of computation and data visualisations. As a result, both biopolitical and sovereign modes of power seem to coexist, with human control room operators
making decisions whose actual significance is difficult to measure. The control room is therefore a key manifestation of a general contemporary anxiety about dematerialisation, virtualisation and information overload, and about the political problems that they entail.
Tenir tête au citron (À propos des revues, ou presque)
Authors: Fiolof Frédéric
Published: January 2020

Carlos Liscano, pour évoquer tout à la fois sa place discrète en littérature et le travail permanent d’écriture auquel il se sentait convoqué, disait ceci : « Parce que nous, les petits écrivains, nous savons que nous avons les mêmes inquiétudes et les mêmes souffrances que les grands. » De la même manière, dans la cuisine d’une revue (objet congru s’il en est) entrent sans doute en action et en contradiction tous les ingrédients qui font les grandes œuvres et les plats étoilés. Petit tour d’horizon.

Cette comédie exige pour les lecteurs d’aujourd’hui une petite introduction sur le contexte.
Couscous, contes, sortilèges. La fabrique de l’écriture d’Elisa Chimenti (Naples 1883-Tanger 1969)
Authors: Cederna Camilla Maria
Published: January 2020

L’auteure essaie d’explorer quelques secrets de la création dans l’œuvre d’Elisa Chimenti, sur le plan du contenu (rituels magiques et religieux) et de l’expression. En particulier dans ses innombrables contes, ces secrets sont liés à la relation d’hostilité entre les sexes, et notamment aux pratiques magiques, aux sortilèges, auxquels les femmes ont recours pour se défendre de leurs ennemis. Mais le secret plus difficile à pénétrer est celui de l’écriture même d’Elisa Chimenti, de ses milliers de pages inédites, monument d’un savoir encyclopédique qui reste encore à découvrir.

Le scandale de la peine
Authors: Mazabraud Bertrand
Published: January 2020

La peine, qui dans son principe répond à une accusation, fut elle-même dénoncée et accusée. Son scandale tiendrait à ses modalités pratiques : inutiles, nuisibles, voire barbares, ou à la faiblesse de son fondement rationnel. Pourtant, à suivre les analyses de Hegel, il apparaît que la peine n’est pas sans raison. Si scandale de la peine il y a, il tient, d’abord, à la faillibilité des décisions humaines qui statuent pour autrui, ensuite, en régime démocratique, à la jointure instable entre le fondement rationnel de la peine et ses modalités pragmatiques. Toutefois, le scandale de la peine offrait aussi un espace de contestation de celle-ci, de réflexion de la société sur elle-même, voire d’amendement. Or, au nom d’un gain d’efficacité, d’une meilleure égalité des justiciables, et de moins d’erreurs de jugement, la rationalité économique, doublée des dispositifs digitaux, reconfigurent désormais les instances pénales. Dès lors, une pénalité diffuse, adhérant au profil de chacun apparaît. À cette aune, le scandale de la peine n’était-il pas un moindre mal, à préserver ?
Arts et pouvoirs. Regards croisés : Chine, Inde, Iran
Authors: Lincot Emmanuel
Published: January 2020

Conçu comme une réflexion collective dynamique, cet article est issu d’un séminaire. Ce dernier s’est échelonné sur trois ans dans le cadre des activités de recherche du cursus Asie de la Faculté des lettres de l’Institut Catholique de Paris. Il s’est donné pour objectif d’apporter une contribution significative à une géographie des arts contemporains en Chine, en Inde et en Iran sous la forme de communications en voie d’être désormais publiées. D’un point de vue méthodologique, ce travail universitaire a été porté par une considération commune selon laquelle, outre la littérature ou les œuvres de pensée, les arts et les pratiques artistiques qui s’y développent permettent de juger de la situation d’une société et de questionner sa mouvante identité.
Les nouveaux ministères en leur site ecclésiologique
Authors: Lesoing Bertrand
Published: January 2020

Les ministères confiés à des fidèles laïcs n’ont pas toujours trouvé leur identité propre, leur point de référence restant trop souvent le ministère ordonné. Si la pluriministérialité est aujourd’hui une donnée de fait, elle n’a pas totalement acquis droit de cité dans l’Église, au moins au niveau des représentations symboliques qui la sous-tendent. Pour sortir de l’ornière, l’article se propose d’approfondir le site ecclésiologique de ces nouveaux ministères. Le modèle d’une Église en sortie missionnaire, qui ne repose plus sur la trop stricte séparation entre Église ad intra et Église ad extra offre une piste pour penser l’identité de ces nouveaux ministères.

Qualitative Analysis of the Disease Experience of Korean Older Men With Chronic Obstructive Pulmonary Disease
Authors: Kim Kisook , Ko Ji Woon , Choi Sangbong
Published: January 2020

The current qualitative study explored perceptions and experiences of chronic obstructive pulmonary disease (COPD) among Korean male older adults. Six older adults participated in a narrative group interview. Responses were analyzed to describe perceptions and experiences of COPD. Social stigma, blaming others and the environment, stress to bear alone, and adaptation and management emerged as relevant themes for adaptation to COPD. In relation to obstacles to healthy behaviors after adapting to COPD, emergent themes were adapting to symptoms, external environmental factors, alternative treatments, and insufficient resources. Facilitators of healthy behaviors were past symptom experience, personal volition, and advice from health professionals. Older adult men with COPD trying to adapt to the disease need sufficient resources and social support from families, social networks, and health professionals. Development of interventions for older adults with COPD should include knowledge and understanding of experience and needs. [

ACTIVATED CARBON BASED SOLUTIONS FOR SPILLS IN REMOTE AND DIFFICULT AREAS
Authors: Sorrells Theresa
Published: January 2020

INTRODUCTION

Environmental calamities such as tanker truck crashes and pipeline leaks do not always occur in well populated areas. Tanker truck crashes can occur on remote mountain passes or lonely stretches of highway. Pipeline leaks can occur in distant areas of open range or other isolated locations.

Treatment of these spills requires the ability to clean up the contamination with very few standard resources. Often these sites will not have access to electricity or cellular service and just getting to the location of the spill can require a long drive from the nearest town. These restrictions can often limit treatment options to those that can be completed quickly and without needing long term access to the site. The remediation of petroleum fuels spilled during several tanker truck roll-overs will be discussed below, along with the obstacles presented by each site and the innovations needed to complete the remediation.

Then, a bibliometric analysis was conducted in order to establish the link between this type of offices and the knowledge management on scientific publications about project management. Afterwards, a comprehensive theoretical framework about the matter of study was build. Subsequently, an information gathering instrument was developed in order to collect data for the research. Next, a nation-wide fieldwork was undertaken by analyzing the organizations. Successively, a detailed statistical analysis was conducted in order to identify the impact of the project management offices on knowledge management within the objects of study. Finally, results and conclusions were documented, and future lines of research were established.
Sustainability on Project Management
Authors: Silva Hugo Fernando Castro , Rincón-González César Hernando , Diez-Silva H. Mauricio
Published: January 2020

Ensuring the conservation of current resources for future generations has become a challenge that from day to day turns to be more important and urgent for society. Despite the fact that sustainability and project management have been subjects of interest in the academic community, few investigations are related to the integration of sustainability within project management, even fewer in the Colombian context. This empirical research work presents results about the perception from a representative sample of project managers from the construction industry in Colombia related to the implementation of elements of sustainability when managing projects established in the maturity model of Salem Azahrani. The results indicate, on one hand, a low average level of maturity and on the other, a higher orientation toward aspects of the economical dimension of the projects in comparison with the social and environmental dimensions.

As part of the institutional innovation project implemented to ensure economic and administrative efficiency besides its strategic alignment, a SAP-based solution was implemented allowing it to move from a technological babel tower with almost 40 independent information systems in multiple platforms, towards a comprehensive platform that ensured a unified interoperability model with a scalable hardware infrastructure, using state-of-the-art applications supporting the provision of self-services to the community, expanding IT capabilities, reducing the risks, increasing the information security, improving the quality of service, and, despite being it in a stabilization stage, has been supporting the operation in an efficient and effective way, as shows the institutional results from the financial and academic quality perspectives.
Standardisation, Data Interoperability, and GDPR
Authors: Pandit Harshvardhan Jitendra , Debruyne Christophe , O'Sullivan Declan , Lewis Dave
Published: January 2020

The General Data Protection Regulation (GDPR) has changed the ecosystem of services involving personal data and information. It emphasises several obligations and rights, amongst which the Right to Data Portability requires providing a copy of the given personal data in a commonly used, structured, and machine-readable format – for interoperability. The GDPR thus explicitly motivates the use and adoption of data interoperability concerning information. This chapter explores the entities and their interactions in the context of the GDPR to provide an information model for the development of interoperable services. The model categorises information and exchanges and explores existing standards and efforts towards use for interoperable interactions. The chapter concludes with an argument for the use and adoption of structured metadata to enable more expressive services through semantic interoperability.
Fostering the Participation of Companies in Standardization
Authors: Sene Christophe
Published: January 2020

Standardization is one source of informal rules that regulate the public realm: standards are not legally-binding, but, as soft law instruments, they influence the governance, ethics, and conduct of companies. Standardization brings unique benefits to companies in term of knowledge, credibility, and risk reduction by bringing accountability and predictability. To foster active participation of companies in standardization, higher and continuous education in standardization is essential to build mutual understanding between companies and the standardization world since decision making in the former is a relatively quick top-down hierarchical process while in the latter time-consuming consensus-building is the norm. The concept of Student Standardization Societies (SSS) is introduced as the best way to promote standardization in the long term, and advice is given for the practical implementation of SSS and their relationship with Official Standardization Organizations.
Technology Transfer to Least Developed Countries Through Global Standards
Authors: Teichmann Hans
Published: January 2020

For the economic growth in least developed countries (LDCs), the transfer of technical and scientific know-how is an uncontested necessity. Poverty and underdevelopment in LDCs are interrelated features. Technology transfers may fail, however, unless varied constraints are taken into account. The focus of this study is on obstacles to an efficient technology transfer to LDCs, and on the major role which global, bilingual standards can play in this process. The global standards setting organizations International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) have recognized the need for a general, comprehensive, and effective support of the LDCs' bodies for national quality infrastructure (NQI). Standardization is not only a vital socio-economic function in itself, but standards represent part of much wider, essential infrastructures. Three stakeholder groups are particularly concerned: the users of the global standards in LDCs, the global standards setting organizations, and the individual National Quality Infrastructure bodies.

It also investigates the attitudes of owners and executives of Russian SMEs toward the concepts of business ethics and social responsibility of business. A research set the background of this chapter, including the gathering of primary data through 57 focused interviews. Results of a critical analysis conclude that top managers and owners of Russian SMEs do not thoroughly understand these concepts. However, it also shows that they do not neglect them. Research findings point to a growing level of adherence to the principles of business ethics and responsible behavior. There is strong evidence showing motivation for following principles of ethical and responsible behavior. In addition to an understanding of legal requirements, company owners and top managers are finding that positive relationships between firms and stakeholders are crucial for sustainable performance.
Trust and Household Portfolios
Authors: Lubian Diego
Published: January 2020

This article provides empirical evidence on the existence and the extent of the influence of trust in financial decisions using individual data on Italian households from the Survey on Household Income and Wealth, 2010. This article studies the relationship between, trust in people, trust in banks and more detailed previously unexplored dimensions of trust, and household financial portfolio decisions. The article provides empirical evidence that trust in people and trust in banks affect both participation in financial markets, the share of risky assets and the diversification of the financial portfolio, controlling socio-demographic factors, risk aversion, and financial literacy as well. The article finds that trust is important for individuals with a lower level of education who have limited possibilities to acquire and process information on financial markets need to rely in trustworthy relationship to define their financial portfolio. Further, we present evidence that the main channel by which trust affects financial decision making and determines too little participation, a lower share of risky assets in the financial wealth and poorly diversified portfolios is trust in family and friends.

Published: January 2020

Infertility is the combination of factors that prevent pregnancy. It involves a lot of care and expertise while selecting the best embryo to lead to a successful pregnancy. Assistive reproductive technology (ART) helps to solve this issue. In vitro fertilization (IVF) is one of the methods of ART which is very popular. Artificial intelligence will have digital revolution and manifold advances in the field of reproductive medicine and will eventually provide immense benefits to infertile patients. The main aim of this article is to focus on the methods that can predict the accuracy of pregnancy without human intervention. It provides successful studies conducted by using machine learning techniques. This easily enables doctors to understand the behavior of the attributes which are suitable for the treatment. Blastocyst images can be deployed for the detection and prediction of the best embryo which has the maximum chance of a successful pregnancy. This pioneering work gives one a view into how this field could benefit the future generation.
Data Dissemination for Vehicles in Temporary Cellular Network Dead Spots
Authors: Puka Ergys , Herrmann Peter
Published: January 2020

The cellular network coverage in sparsely populated and mountainous areas is often patchy. That can be a significant impediment for services based on connections between vehicles and their environment. This article presents a method to reduce the waiting time occurring when a vehicle intends to send a message via a cellular network but is currently in a dead spot, i.e., an area without sufficient coverage. The authors introduce a data dissemination protocol that allows vehicles to connect through an ad-hoc network. The ad-hoc network peers can then find out which one will most likely leave the dead spot first. The selected vehicle stores then the messages of all connected vehicles and forwards them to the remote infrastructure as soon as it regains cellular network access. This research also discusses message flows in larger dead spots in which a vehicle may consecutively form several ad-hoc connections. Further, the authors describe an initial implementation of the protocol using the technology Wi-Fi Direct that is realized on most modern mobile phones.
Assessing the Effects of Digital Technologies on Learning Behavior and Reading Motivation Among Moroccan EFL University Students
Authors: Larhmaid Maryem , Nour Taibi , Afflerbach Peter
Published: January 2020

The introduction of digital technologies and the emergence of electronic reading devices have expanded the concept of literacy and shaped how readers consume information from texts, as well as how they perceive and interact with digital materials vs. print materials in academic settings. Several years ago, reading was merely a characteristic of print. However, with today's advances in technology, the vast majority of people are reading blogs, journals, newspapers, and other materials on digital screens. This study reports the findings of a survey on the effects of digital technologies on learning behavior and reading motivation among Moroccan EFL university students. Results showed that the majority of students reported using digital materials for studying, research, and recreational purposes. The majority of students also reported using desktop/laptop computers or smartphones to access digital materials and claimed that they frequently consult PDF documents and Google books for coursework materials. Additional findings suggest that print reading is favored when the reading task includes lengthy texts and demands more learning engagement activities such as highlighting and notetaking; and that digital reading is preferred when the reading task demands less effortful engagement activities, and includes short texts and accessible materials via the Internet at a preferential cost. Students reported that their motivation to read online is driven by the need to keep up with recent information as well as the need to use usability features embedded with e-texts such as the ‘Find' function and built-in annotation tools. A great number of students rated their overall online reading experience as satisfactory or enjoyable. In contrast, students reported that eyestrain, discomfort with online reading, as well as the credibility and quality of texts encountered online are major challenges and barriers to digital reading. Results revealed that students' satisfaction with online reading is positively correlated with the frequency of using digital texts. Additional implications and directions for future research are considered.
Research on the Anthropogenic Impact on Climate Change
Authors: Vinogradov Yuri , Strebkov Dmitry
Published: January 2020

The article is a presentation of the results of studies and calculations of climate parameters associated with anthropogenic thermal pollution of the environment. They indicate that the increase of atmospheric concentrations of carbon dioxide, methane, and nitrous oxide cannot be a cause of climate warming. The article provides information about the working principle of the natural mechanism of automatic maintenance of temperature climate parameters. The authors show that all of the gases molar mass of differs from the molar mass of nitrogen are the working bodies of the procedures for moving heat from the stratosphere to space. Water vapor is the only greenhouse gas, and to deal effectively with water vapor in the atmosphere is impossible. However, the work contains an assessment of the feasibility of some ways to assist the natural mechanism of removing heat to space. Some methods and tools of world energy development are suggested in the article. These methods could lead to a substantial reduction of anthropogenic thermal pollution of the planet.
Investigation of the Methods of Self-Heating Climate Prevention
Authors: Strebkov Dmitry
Published: January 2020

The investigation has shown that the main cause of the global climate change is “anthropogenic thermal pollution,” which is created by the activity of mankind and creates the prerequisites for breaking the heat balance of the planet and transferring the climate into a state of self-heating. By different estimates, in 20-60 years there could be a point of no return for the warming of the climate of Earth when no material resources of mankind are able to stop the global disaster connected with thawing of glaciers, increasing level of the ocean of 80-100 m and the transition of the Earth climate to a condition incompatible with biological life. Urgent transition to fuel-free power and a change of radiation balance of Earth by increasing the albedo of the cities and deserts is necessary. Calculating the area of specular reflectors and the area of deserts necessary for their location, are necessary to prevent global warming, and showed that the required area is 0.95-1.21% of the area of the African desert.
Aggregate Searchable Encryption With Result Privacy
Authors: Sharma Dhruti P. , Jinwala Devesh C.
Published: January 2020

With searchable encryption (SE), the user is allowed to extract partial data from stored ciphertexts from the storage server, based on a chosen query of keywords. A majority of the existing SE schemes support SQL search query, i.e. 'Select * where (list of keywords).' However, applications for encrypted data analysis often need to count data matched with a query, instead of data extraction. For such applications, the execution of SQL aggregate query, i.e. 'Count * where (list of keywords)' at server is essential. Additionally, in case of semi-honest server, privacy of aggregate result is of primary concern. In this article, the authors propose an aggregate searchable encryption with result privacy (ASE-RP) that includes ASearch() algorithm. The proposed ASearch() performs aggregate operation (i.e. Count *) on the implicitly searched ciphertexts (for the conjunctive query) and outputs an encrypted result. The server, due to encrypted form of aggregate result, would not be able to get actual count unless having a decryption key and hence ASearch() offers result privacy.

Published: January 2020

Electronic examination systems are becoming increasingly complex and intensive to develop with the introduction of virtual invigilator in proctored examinations. In order to address this complexity issue, there is evident need to have a global model that is extensible. Modeling software systems enables developers to better understand the system they are building and offers opportunities for simplification and reuse. This article presents an extension to UMLsec, by introducing three (3) new stereotypes which were added to the UMLsec Profile for a Proctored e-Exam model. The model was validated and converted to a platform specific model using the Java stereotype available on Papyrus. This enabled the model generate Java classes which can be used for the implementation of a secure proctored e-exam system. The model allows developers with little or no knowledge in security to use the model to build proctored e-exam systems and to incorporate all known security requirements. The model can also be extended to accommodate new security solutions for e-exam systems as they are discovered.

Published: January 2020

The advent of smartphones revolutionized and took the market to a new level. Now a days, majority of internet users spend their maximum time on smartphones, specifically on mobile apps. The emergence of numerous apps in smartphones with games features has brought about a different trend, mobile app gamification. The emerging popularity of smartphone technologies and their mobile apps have led various companies to engage their consumers with mobile apps, specifically through gamification. Therefore, companies gain consumers attention integrate their mobile marketing into their overall marketing strategy. This study explores the domain of consumer engagement and their intentions through the gamification of mobile apps. The research focuses on how mobile app gamification drives consumer engagement and their intentions drawing upon SDT and TAM. Using survey method data collected from 270 respondents, data analysis was done with structure equation modeling (SEM). The findings assert that various features of gamification of mobile apps (perceived ease of use, perceived usefulness and enjoyment) have a significant influence on consumer engagement. However, convenience was unexpectedly found not to be significantly associated with consumer engagement. Additionally, consumer engagement was found to be associated to smartphone user's intentions to use gamification of mobile apps. The results of present study have theoretical and practical implications.

Household access to agricultural credit and agricultural production in Nigeria: A propensity score matching model
Authors: Osabohien Romanus , Osuagwu Eze , Osabuohien Evans , Ekhator-Mobayode Uche Eseosa , Matthew Oluwatoyin , Gershon Obindah
Published: January 2020

Background: Agricultural production is low in Nigeria as a result of low utilisation of farm inputs facilitated by farmers’ inability to save and invest. Therefore, credit is needed by farmers to enhance their productive capacity and efficiency in agriculture.Aim: Given the importance of credit to farmers, this study examined the nexus between households’ access to credit and agricultural production in Nigeria.Setting: The study made use of data from the Living Standard Measurement Study-Integrated Survey on Agriculture (LSMS-ISA) consisting of 4210 households across the 36 states in Nigeria, as well as the Federal Capital Territory, Abuja.Methods: The study employs the propensity score matching (PSM) technique.Results: The main result from the study suggests that households who had access to agricultural credit facilities had yields that are thrice those of their counterparts who did not benefit from such facilities. In the event of a shock, the farmers who did not have a source of credit are often forced to adopt measures such as lowering consumption and selling assets, which in the long run worsen their poverty levels.Conclusion: The study recommends that policymakers should address underlying factors that prevent access to credit for agricultural production, which is capable of raising the productive capacities of farmers.

Uma proposta de teoria unificada de fatores nominais e verbais na marcação diferencial do objeto
Authors: Moura Heronides
Published: January 2020

A questão principal deste artigo é a seguinte: de um ponto de vista tipológico, qual é generalização semântica mais significativa subjacente à marcação diferencial do objeto (DOM)? Minha proposta é que o DOM é motivado pela presença, em sentenças transitivas, de porções altamente individuadas de matéria e de tempo. Faço uso de um conceito mais amplo de porções individuadas, abrangendo tanto a noção de eventos completos quanto a individuação de referentes. Tal como no domínio da matéria existem objetos delimitados, no domínio do tempo existem eventos delimitados (PINKER, 2008). Este conceito mais amplo de porções individuadas possibilita uma explicação mais satisfatória do DOM. Não existe uma teoria que tente unificar as diferentes motivações do DOM. Não há uma explicação para a relação entre a semântica do verbo e a semântica do sintagma nominal no DOM. Nossa proposta é que estes diferentes fatores podem ser unificados em uma única teoria.

Authors: Lessa-de-Oliveira Adriana Stella Cardoso , Alves Marcelo Meira
Published: January 2020

O presente estudo tem como objeto a categoria Tempo na aquisição do Português Brasileiro escrito por surdos. Para esta investigação, fundamentamo-nos na teoria gerativista, admitindo a hipótese inatista de aquisição da linguagem. No âmbito da aquisição de L2, assumimos a hipótese de acesso indireto à Gramática Universal (GU). Nosso corpus se constitui de amostras naturalísticas – textos produzidos em ambiente escolar. Os resultados indicam ocorrência, na interlíngua estudada, de operadores temporais específicos da Libras – os itens lexicais passado e futuro e advérbios. Marcando Tempo passado, observou-se ocorrência de operador lexical em casos de verbos com Aspecto não pontual e a dispensa desse em casos de verbos com Aspecto perfectivo, como ocorre na Libras, conforme estudo de Silva (2015) e Silva e Lessa-de-Oliveira (2016), o que caracteriza acesso indireto à GU no processo de aquisição da L2. As produções escritas também apresentaram flexão temporal conforme o Português Brasileiro e a realização de verbos auxiliares marcando Tempo futuro.
Linguística popular/folk linguistics e linguística científica: Em vez do versus, propomos a integração
Authors: Baronas Roberto Leiser , Cox Maria Inês Pagliarini
Published: January 2020

Este dossiê (re)inaugura  a possibilidade de compreender os estudos da linguagem, produzidos em solo brasílico, não mais a partir de uma relação dicotômica: de um lado, os estudos científicos, pertinentes, relevantes e, de outro, os saberes populares, profanos, equivocados acerca da língua. Trata-se de pensar na esteira da pesquisadora francesa Marie-Anne Paveau (2008) para quem as abordagens científica e popular são antieliminativas.  Como sabiamente afirma essa autora “os enunciados populares não são necessariamente crenças falsas, equivocadas a serem eliminadas da ciência. Constituem ao contrário saberes perceptivos, subjetivos e incompletos a serem integrados aos dados científicos da linguística”.

Neste trabalho, fortemente apoiados na tese de Marie-Anne Paveau (2008) de que as abordagens da linguística popular/folk linguistics e das ciências da linguagem em geral são antieliminativas, isto é, as práticas linguísticas dos locutores profanos, os não-linguistas, mesmo aquelas de natureza mais prescritiva, são perfeitamente integráveis às análises linguísticas, propostas pelos linguistas, analisamos discursivamente de maneira não exaustiva um trabalho em linguística popular, que circula no contexto brasileiro no formato dicionário, a saber: o Dicionário Aurélia: a dicionária da língua afiada, publicado em 2006, pela Editora Bispa, de autoria dos jornalistas Vitor Angelo Scippe e Fred Libi.
Can seafloor voltage cables be used to study large-scale circulation? An investigation in the Pacific Ocean

Abstract. Marine electromagnetic (EM) signals largely depend on three factors: flow velocity, Earth's main magnetic field, and seawater's electrical conductivity (which depends on the local temperature and salinity). Because of this, there has been recent interest in using marine EM signals to monitor and study ocean circulation. Our study utilizes voltage data from retired seafloor telecommunication cables in the Pacific Ocean to examine whether such cables could be used to monitor circulation velocity or transport on large-oceanic scales. We process the cable data to isolate the seasonal and monthly variations, and evaluate the correlation between the processed data and numerical predictions of the electric field induced by ocean circulation. We find that the correlation between cable voltage data and numerical predictions strongly depends on both the strength and coherence of the velocities flowing across the cable, as well as the length of the cable. The cable within the Kuroshio Current had the highest correlation between data and predictions, whereas two of the cables in the Eastern Pacific gyre – a region with both low flow speeds and interfering velocity directions across the cable – did not have any clear correlation between data and predictions. Meanwhile, a third cable also located in the Eastern Pacific gyre had modest correlation between data and predictions – although the cable is very long and the speeds were low, it was located in a region of coherent flow velocity across the cable. While much improvement is needed before utilizing seafloor voltage cables to study and monitor oceanic circulation across wide regions, we believe that with additional work, the answer to our title's question may eventually be yes.
A decade of variability on Jakobshavn Isbræ: ocean temperatures pace speed through influence on mélange rigidity

Abstract. The speed of Greenland's fastest glacier, Jakobshavn Isbræ, has varied substantially since its speed-up in the late 1990s. Here
we present observations of surface velocity, mélange rigidity, and
surface elevation to examine its behaviour over the last decade. Consistent
with earlier results, we find a pronounced cycle of summer speed-up and
thinning followed by winter slowdown and thickening. There were extended
periods of rigid mélange in the winters of 2016–2017 and 2017–2018,
concurrent with terminus advances ∼6 km farther than in the
several winters prior. These terminus advances to shallower depths caused
slowdowns, leading to substantial thickening, as has been noted elsewhere.
The extended periods of rigid mélange coincide well with a period of
cooler waters in Disko Bay. Thus, along with the relative timing of the
seasonal slowdown, our results suggest that the ocean's dominant influence
on Jakobshavn Isbræ is through its effect on winter mélange rigidity,
rather than summer submarine melting. The elevation time series also reveals
that in summers when the area upstream of the terminus approaches flotation,
large surface depressions can form, which eventually become the detachment
points for major calving events. It appears that as elevations approach
flotation, basal crevasses can form, which initiates a necking process that
forms the depressions. The elevation data also show that steep cliffs often
evolve into short floating extensions, rather than collapsing
catastrophically due to brittle failure. Finally, summer 2019 speeds were
slightly faster than the prior two summers, leaving it unclear whether the
slowdown is ending.
FATIGUE CRACK GROWTH AND FATIGUE FRACTURE MORPHOLOGY OF RECYCLED RUBBER POWDER–FILLED NR/BR BLEND COMPOUND

The effect of two different types and particle sizes (micronized cryo-ground 74 μm or ambient-ground 400 μm) of recycled rubber powder (RRP) was studied during fatigue crack growth (FCG) in a natural rubber/butadiene rubber (NR/BR) compound using a fracture mechanics approach. Absolute and relative hysteresis losses using single-edge notch tensile specimens were determined with a displacement-controlled strain compensating for the permanent set of the samples throughout the FCG experiments. Differences in relative hysteresis loss showed that additional energy dissipation, due to multiple new crack surfaces at the crack tip, contributes to the FCG of the RRP compounds. At higher tearing energy, beside other factors affecting the FCG performance of the RRP compounds, both higher absolute and relative hysteresis loss are slightly detrimental to the crack growth rates. At lower tearing energy, the larger RRP-filled compound showed slower, but not significant, different crack growth rates than the NR/BR control compound. Fracture morphologies for NR/BR and RRP-filled compound were associated with different fracture surface topographies at various tearing energies, which revealed the dependency of the crack growth microstructure on the tearing energies.
Geochemistry of Bivalve Shells As Indicator of Shore Position of the 2nd Century BC

Published: January 2020

In an area named Mermian (municipality of Agde, South of France), a significant amount of fragmented italic amphorae from the 2nd century BC was discovered, located at a depth of 6 to 8 meters under the bed of the Hérault river. As no ship wreck was found in the vicinity, the reason of the presence of these amphora fragments, whose faces present a large accumulation of oyster shells, is unknown. Reconstructed geomorphological maps of the area present Mermian as a riverine site already at this period, and several hypothetical explanations on the role of these amphorae exist (landfill linked to a neighbouring habitat, bank reinforcement linked to a ford crossing, river landing, etc.). In order to define whether the amphorae were transported to this location and from where, we analysed the stable carbon and oxygen isotopes of the oyster shells. The δ13C and δ18O indicate that all oysters lived in the same environment, refuting a potential transport during the oyster accumulation. Moreover, the analysis of Mytilaster sp. shells in the sediment around the oyster shells also reported a marine origin, suggesting that these oysters were also buried in a marine deposit. Transport to Mermian from a coastal locality is unlikely but may still have happened, although no trace of human handling were observed on the fragments. Still, the presence of other marine or brackish molluscs in the sediment discards the interpretation of Mermian being a continental locality.
