influência dos escritos judaicos de I Enoque, II Enoque e III Enoque no desenvolvimento da literatura apocalíptica islâmica medieval
Authors: Guimarães Filipe de Oliveira
Published: October 2021

Nos primeiros séculos da Era Comum, foi ampla a utilização da literatura atribuída a Enoque entre os cristãos, principalmente o livro de I Enoque, mas também, de forma mais discreta, os escritos de II Enoque e III Enoque (este o que menos exerceu influência). O posicionamento oficial, no cristianismo ocidental, que descredenciou essa tradição como literatura útil à religiosidade cristã, deu-se no Concílio de Laodiceia (século VI) ao estabelecer que os únicos nomes de anjos reconhecidos como sagrados seriam Miguel, Gabriel e Rafael, afastando I Enoque (que cita vários nomes de anjos) o cenário exegético cristão ocidental por séculos. Entre os judeus, a literatura foi bastante influente até o Concílio de Jâmnia, final do século I, que considerou como sagrados para a religião os textos produzidos nos limites da Terra Santa, em língua hebraica, marginalizando I Enoque redigido originalmente em aramaico. Porém, o mesmo não aconteceu em algumas regiões do Oriente onde o Cristianismo continuou a utilizar-se do escrito. Partindo do prisma de que o Islamismo é uma religião monoteísta cujo nascedouro produziu intercâmbios intensos com literaturas judaico- cristãs, o artigo aponta para uma plausível influência do livro de I Enoque na construção da apocalíptica islâmica tomando como base comparativa o livro La Escala de Mahoma. O artigo é de natureza bibliográfica e está estruturado sobre o método comparativo, objetivando apresentar confluências narratológicas entre os escritos.

IMPACT OF CHEMICAL THINNING TO IMPROVE FRUIT CHARACTERISTICS OF DATE PALM CULTIVAR KHALAS
Authors: & et al. Ghazzawy
Published: October 2021

A field study was conducted to observe the effects of chemical fruit thinning and their time of application on fruit yield and quality of date palm cv. Khalas at Date Palm Research Center of Excellence, King Faisal University, Saudi Arabia. Fourteen date palm trees were randomly selected for the experiment, which was laid out on two-factorial randomized complete block design having six replicates for each treatment. Factor-one comprised of the six chemical (ammonium thiosulphate at 1, 2, and 3% and ethephon at 100, 200 and 300ppm) excluding control, whereas the second factor was the time of application of these two chemical thinners (5 and 10 days after pollination). The findings of this study indicated that the chemical fruit thinning had definite effects on virtually all fruit quality characteristics. Early application of chemical thinners after 5 days of pollination, significantly decreased the total fruits drop percentage and enhanced number of retained fruits, bunch weight, yield per palm, fruit color, fruit weight and length, seed weight, TSS, total and reducing sugars. On the other hand, among chemical thinners, the application of ethephon at 300 ppm significantly improved previously mentioned parameters. Similarly, ethephon at 200 or ATS at 3% also showed promising results. It is therefore, concluded that the application of ethephon at 200 or 300ppm after 5 days of pollination influenced significantly regarding fruit yield and quality parameters of date palm cv. Khalas.
Weakly Supervised Learning for Textbook Question Answering
Authors: Ma Jie , Chai Qi , Huang Jingyue , Liu Jun , You Yang , Zheng Qinghua
Published: October 2021

Textbook Question Answering (TQA) is the task of answering diagram and non-diagram questions given large multi-modal contexts consisting of abundant text and diagrams. Deep text understandings and effective learning of diagram semantics are important for this task due to its specificity. In this paper, we propose a Weakly Supervised learning method for TQA (WSTQ), which regards the incompletely accurate results of essential intermediate procedures for this task as supervision to develop Text Matching (TM) and Relation Detection (RD) tasks and then employs the tasks to motivate itself to learn strong text comprehension and excellent diagram semantics respectively. Specifically, we apply the result of text retrieval to build positive as well as negative text pairs. In order to learn deep text understandings, we first pre-train the text understanding module of WSTQ on TM and then fine-tune it on TQA. We build positive as well as negative relation pairs by checking whether there is any overlap between the items/regions detected from diagrams using object detection. The RD task forces our method to learn the relationships between regions, which are crucial to express the diagram semantics. We train WSTQ on RD and TQA simultaneously, \emph{i.e.}, multitask learning, to obtain effective diagram semantics and then improve the TQA performance. Extensive experiments are carried out on CK12-QA and AI2D to verify the effectiveness of WSTQ. Experimental results show that our method achieves significant accuracy improvements of $5.02\%$ and $4.12\%$ on test splits of the above datasets respectively than the current state-of-the-art baseline. We have released our code on \url{https://github.com/dr-majie/WSTQ}.

Hal-hal yang dianalisis meliputi 1) rima, 2) imajinasi, 3) diksi, 4) kata konkret, 5) majas. Penelitian ini dilakukan dengan tujuan untuk mendeskripsikan kemampuan siswa kelas VIII semester genap SMP Perintis 2 Bandar Lampung Tahun Pelajaran 2019/2020, dalam menulis puisi berdasarkan tema yang telah ditentukan dan mengetahui berbagai faktor yang dapat menyebabkan kesulitan siswa dalam menulis puisi.Metode penelitian yang digunakan dalam penelitian ini yakni deskriptif kualitatif. Subjek penelitian ini adalah semua kelas VIII semester genap SMP Perintis 2 Bandar Lampung Tahun Pelajaran 2019/2020, berjumlah 354 siswa, terbagi ke dalam 8 kelas dengan subjek inti sebanyak 35 orang yang diambil dengan teknik random sampling. Teknik pengumpulan data penelitian menggunakan teknik tes unjuk kerja yakni menugaskan siswa untuk menulis puisi berdasarkan tema yang telah ditentukan. Teknik analisis data menggunakan deskriptif kualitatif, yakni dengan menganalisis ketepatan siswa menulis puisi berdasarkan aspek yang dinilai.Hasil penelitian menunjukkan bahwa kemampuan siswa kelas VIII semester genap SMP Perintis 2 Bandar Lampung Tahun Pelajaran 2019/2020, dalam menulis puisi belum sepenuhnya dapat dikatakan berhasil. Hal ini disebabkan karena masih ada unsur-unsur yang  kurang tepat dalam menulis puisi. Kesalahan atau kelemahan siswa yang sering ditemukan yaitu pada aspek rima, diksi dan kata konkret. Umumnya, setiap siswa dalam menulis puisi kurang tepat atau tidak menggunakan aspek tersebut. Puisi yang ditulis  siswa terkesan seperti prosa, kata-kata yang datar dan biasa, sehingga kurang memberikan nilai keindahan. Tidak adanya kesamaan rima pada tiap baitnya juga merupakan salah satu  kelemahan siswa, rima cenderung tidak mengikuti pola dengan baik, sehingga rima pada puisi tidak jelas dan menimbulkan ketidakselarasan. Kata-kata yang datar juga mempengaruhi aspek diksi karena dapat membuat puisi kurang menarik sehingga tidak terkesan pada nilai-nilai keindahan sebuah karya sastra.
Somaliland women’s perception of stillbirth - a descriptive survey study
Authors: Malm Mari-Cristin , Osman Fatumo , Ahmed Ibrahim A. , Farah Hasan H. , Erlandsson Kerstin , Kiruja J. , Kalucza Sara
Published: October 2021

Background: Somali women, not only those living in Somaliland but also those living abroad as asylum seekers and refugees, are highly vulnerable in terms of perinatal health outcomes. Respectful and supportive care is critical for all women when stillbirth occurs and improving bereavement care and reducing the stigma that surrounds stillbirth are global priorities. Culturally- and context-specific approaches that build on an understanding of the needs of women giving birth to a stillborn baby, no matter where or why, are required.
Objective: This study aims to investigate and analyze Somali women’s experiences of stillbirth, including their perceived reasons for losing their unborn baby, the premonitions they had before giving birth and their experiences of psychosocial support from healthcare professionals and relatives.
Methods: A descriptive retrospective study was conducted at the Borama regional hospital in Somaliland. A study-specific questionnaire was developed that gathered personal information and data on topics related to women’s experiences of stillbirth. Women who had either experienced a stillbirth at the hospital or had been referred there after a stillbirth 2015 were approached and 75 women agreed to participate in the study.
Results: Most of the women were multiparas and had experienced a previous stillbirth. Before having it confirmed that their baby was no longer alive most of the woman reported that they had felt no fetal movements and had a premonition that something was wrong. The most common perceived cause of stillbirth that the women reported was prolonged labour followed by a ‘big baby’. Thirty-three women (44%) felt it was important to know the cause of the stillbirth and eight reported feeling angry or disappointed (11 %) with the health care providers who assisted them during labour, birth, or post-partum, although 41 women (55%) were satisfied with their treatment. A third of the women blamed themselves for their stillbirth and a majority spoke to others about it.
Conclusions: Our results show that women in Somaliland share similar perceptions of stillbirth as women in high income countries. This raises important implications for antenatal care and preventive interventions and stressed the need to respond to women’s concerns regardless of background, context or setting. A maternal healthcare approach that is equal in its global application must be established to enable health care providers to give relevant information and care both in the cultural setting of Somaliland and elsewhere in the world where Somali-born women live and give birth.

Misinformation interventions are common, divisive, and poorly understood
Authors: Saltz Emily , Barari Soubhik , Leibowicz Claire , Wardle Claire
Published: October 2021

Social media platforms label, remove, or otherwise intervene on thousands of posts containing misleading or inaccurate information every day. Who encounters these interventions, and how do they react? A demographically representative survey of 1,207 Americans reveals that 49% have been exposed to some form of online misinformation intervention. However, most are not well-informed about what kinds of systems, both algorithmic and human, are applying these interventions: 40% believe that content is mostly or all checked, and 17.5% are not sure, with errors attributed to biased judgment more than any other cause, across political parties. Although support for interventions differs considerably by political party, other distinct traits predict support, including trust in institutions, frequent social media usage, and exposure to “appropriate” interventions.

The evolution of the noun class system of Ngwi (West-Coastal Bantu, B861, DRC)
Authors: Pacchiarotti Sara , Bostoen Koen
Published: October 2021

In this paper we offer a first systematic account of the noun class system of Ngwi, a West-Coastal Bantu language spoken in the Democratic Republic of the Congo. First, we describe the synchronic system of noun class prefixes and the agreement patterns they trigger on constituents of the noun phrase and the verb. Second, we provide a diachronic analysis of the innovations the synchronic Ngwi noun class system underwent with respect to the noun class system reconstructed for the most recent common ancestor of all Narrow Bantu languages. Finally, we compare the morphological innovations found in the Ngwi noun class system with those identified in the noun class systems of other West-Coastal Bantu varieties and assess whether some of these could be diagnostic for internal classification within this western Bantu branch.
Word or otherwise? The status of the copula no in Guinean Pular
Authors: Kosogorova Maria
Published: October 2021

The paper analyzes the morphosyntactic status of a copula no as part of complex verbal predicates of Guinean Pular. A locative copula no, combined with various forms of lexical verb, adds up to three verbal constructions. Morphological and semantic non-compositionality of no in such constructions questions its morphosyntactic status as a free word and suggests that it might be an affix or a clitic. Pular data has been subjected to a series of tests using a set of phonological, morphological, and semantic criteria. The results of the phonological tests show that no in complex verbal predicates cannot be a free word, whereas the morphological tests deny it the status of an affix. It is, therefore, concluded that this copula is a clitic, which is confirmed by the language data complying with general morphological and phonological criteria.
Anticancer activity of Mandragora autumnalis: an in vitro and in vivo study
Authors: Mahmod Asma Ismail , Talib Wamidh H.
Published: October 2021

Ethanol crude extract and four solvent fractions were extracted from M. autumnalis leave to evaluate their anticancer effect in both models: in vitro and in vivo. The in vitro assessments were conducted using the MTT method in five cancer cell lines and one normal cell line. Ethanol extract and n-hexane fraction showed antitumor activity against MCF-7 breast cancer cells with IC₅₀ values of 0.1 and 0.4 mg/ml, respectively, and low cytotoxicity against normal VERO cell line (IC₅₀ value > 4 mg/ml). Furthermore, expression levels of VEGF were tested in MCF-7 cells treated with M. autumnalis using Human VEGF Simple Step ELISA Kit. The results indicated downregulation of VEGF expression in the treated cells compared to the control group. Additionally, the LD₅₀ of M. autumnalis ethanol extract was calculated by applying an acute toxicity assay. Balb/C mice were inoculated with EMT6/p breast cancer cells and then treated with (137 mg/kg/day intraperitoneal injection) of ethanol extract for ten days. Interestingly, a significant (p < 0.001) reduction occurred in the tumor size of the treated group comparing to the control. Treatment in vivo toxicity was evaluated by measuring liver and kidney parameters. The tumor-bearing mice treated with the M. autumnalis extract showed normal serum level of AST, ALT, and creatinine. The results indicate that M. autumnalis has antitumor properties in both models in vitro and in vivo. However, further molecular investigation is required to understand the molecular bearings of M. autumnalis’ activity.
La construction d’un « marché éduqué » de l’assurance santé : une réorientation de la solidarité ?
Authors: Batifoulier Philippe , Duchesne Victor , Ginon Anne-Sophie
Published: October 2021

Le développement de la couverture complémentaire des frais de santé en France s’accompagne d’un mouvement de grande ampleur qui consiste à promouvoir au sein de l’ensemble du champ de l’assurance maladie complémentaire des missions et des valeurs traditionnellement caractéristiques des services publics. Nous proposons de nommer « marché éduqué » cet ensemble de dispositifs juridiques qui configurent le marché de l’assurance santé, pour l’imprégner de valeurs sociales et « l’élever » à une autre forme de mutualisation plus solidaire. Ce texte repose sur une analyse bi-disciplinaire droit et économie. Il analyse la façon dont se construit ce marché éduqué et renouvelle l’intervention publique en matière de couverture santé. À partir d’une comparaison avec les États-Unis, nous montrons que le « marché éduqué » constitue une forme moderne de résolution des contradictions entre la priorité donnée au développement du marché et la tentative de préservation de la mission sociale de la couverture des frais de santé.
The Role of Impulsive Decision Making on Health Behavior Related to Cardiovascular Disease Risk Among Older Adults With Hypertension
Authors: van den Berk-Clark Carissa , Pickard Joe , Davis Dawn , Scherrer Jeffrey F.
Published: October 2021

The purpose of the current study was to investigate whether older adults who are more impulsive also tend to engage in more health behaviors associated with increased risk for cardiovascular disease (CVD). We analyzed data from the Health and Retirement Study. Logistic regression analysis was performed to determine the likelihood of medication adherence, alcohol consumption, and exercise among older adults with hypertension. Adjusted regression results revealed higher impulsive decision making was associated with greater likelihood of obesity (odds ratio [OR] = 2.96, 95% confidence interval [CI] [1.00, 8.92]), lower likelihood of medication adherence (OR = 0.37, 95% CI [0.15, 0.92]), and regular drinking (OR = 0.36, 95% CI [0.15, 0.87]). Higher impulsive decision making was associated with lower likelihood of regular exercise only in unadjusted models. Older adults with hypertension who had higher impulsive decision making engaged in health behaviors associated with increased risk for CVD. Health care providers should consider the range of strategies offered through behavioral economics to improve health in these at-risk populations. [

Consider the transmission eigenvalue problem

   \begin{document}$ (\Delta+k^2\mathbf{n}^2) w = 0, \ \ (\Delta+k^2)v = 0\ \ \mbox{in}\ \ \Omega;\quad w = v, \ \ \partial_\nu w = \partial_\nu v\ \ \mbox{on} \ \partial\Omega. $\end{document}

It is shown in [16] that there exists a sequence of eigenfunctions \begin{document}$ (w_m, v_m)_{m\in\mathbb{N}} $\end{document} associated with \begin{document}$ k_m\rightarrow \infty $\end{document} such that either \begin{document}$ \{w_m\}_{m\in\mathbb{N}} $\end{document} or \begin{document}$ \{v_m\}_{m\in\mathbb{N}} $\end{document} are surface-localized, depending on \begin{document}$ \mathbf{n}>1 $\end{document} or \begin{document}$ 0<\mathbf{n}<1 $\end{document}. In this paper, we discover a new type of surface-localized transmission eigenmodes by constructing a sequence of transmission eigenfunctions \begin{document}$ (w_m, v_m)_{m\in\mathbb{N}} $\end{document} associated with \begin{document}$ k_m\rightarrow \infty $\end{document} such that both \begin{document}$ \{w_m\}_{m\in\mathbb{N}} $\end{document} and \begin{document}$ \{v_m\}_{m\in\mathbb{N}} $\end{document} are surface-localized, no matter \begin{document}$ \mathbf{n}>1 $\end{document} or \begin{document}$ 0<\mathbf{n}<1 $\end{document}. Though our study is confined within the radial geometry, the construction is subtle and technical.

Published: October 2021

Internet of things (IoT) systems are composed of variety of units from different domains. While developing a complete IoT system, different professionals from different domains may have to work in collaboration. In this paper we provide a framework which allows using discrete and continuous time modeling and simulation approaches in combination for IoT systems. The proposed framework demonstrates on how to model Ad-hoc and general IoT systems for software engineering purpose. We demonstrate that model-based software engineering on one hand can provide a common platform to overcome communication gaps among collaborating stakeholders whereas, on the other hand can model and integrate heterogeneous components of IoT systems. While modeling heterogeneous IoT systems, one of the major challenges is to apply continuous and discrete time modeling on intrinsically varying components of the system. Another difficulty may be how to compose these heterogeneous components into one whole system. The proposed framework provides a road-map to model discrete, continuous, Ad-hoc, general systems along with composition mechanism of heterogeneous subsystems. The framework uses a combination of Agent-based modeling, Aspect-oriented modeling, contract-based modeling and services-oriented modeling concepts. We used this framework to model a scenario example of a service-oriented IoT system as proof of concept. We analyzed our framework with existing systems and discussed it in details. Our framework provides a mechanism to model different viewpoints. The framework also enhances the completeness and consistency of the IoT software models.

Authors: Cruz Mirian Oliveira , Miranda Gilberto José , Leal Edvalda Araujo
Published: October 2021

A motivação é essencial para o envolvimento dos estudantes com o ensino, podendo o professor ser protagonista nesse processo por meio do controle ou da promoção de autonomia em sala de aula. Este estudo teve como objetivo identificar os estilos motivacionais de professores de Ciências Contábeis no Brasil por intermédio do instrumento de avaliação denominado Problems in School que foi elaborado por Deci et al. (1981) e revisado e validado por Bzuneck e Guimarães (2007). Para alcançar esse objetivo, o questionário foi aplicado a uma amostra de 182 docentes atuantes no curso de Ciências Contábeis. A estatística descritiva revelou a preferência dos docentes por estratégias de promoção de autonomia. Ao analisar os estilos motivacionais, considerando o gênero, constatou-se, por meio de testes de diferença de médias (Mann-Whitney U), que as mulheres se apresentam significativamente mais promotoras de autonomia que os homens. Também foi constatado que os docentes que tem formação continuada tendem a apresentar estilos motivacionais com maior nível de autonomia que os demais. Esses resultados reforçam a necessidade de formação pedagógica inicial e continuada dos docentes que atuam na área contábil.
Gestão Estratégica de Custos: Um Estudo da Construção do Campo de Conhecimento Brasileiro sob a Ótica da Teoria Ator-Rede (TAR)
Authors: Costa Simone Alves da
Published: October 2021

O objetivo deste estudo é investigar como vem sendo construído o processo de geração, disseminação e utilização do campo de conhecimentos da Gestão Estratégica de Custos (GEC), sob a ótica da Teoria Ator-Rede (TAR). A metodologia de pesquisa proposta utilizou de entrevistas semiestruturadas, observação participante e análise de conteúdo referente a periódicos, cursos e livros de referências na área. Foram 22 entrevistas que contaram com 24 entrevistados entre docentes, pesquisadores, coordenadores, editores, avaliadores etc. Desses, dezessete são brasileiros e cinco da Alemanha, Estados Unidos, Inglaterra, Itália e Portugal. Também foram registradas 80 horas de observação em eventos da área, juntamente com material de oito periódicos, dezesseis livros e sete cursos de referência. Desse material, pela análise de conteúdo, emergiram três categorias que auxiliam na visualização da construção do campo: Domínio, Contexto e Conceito. Como resultados, foi possível notar que a construção do campo de conhecimentos da GEC se deu sob argumentos de autoridade, que favoreceram os processos de translação, necessários ao desenvolvimento da rede. Ainda, foi gerada uma rede de convergência baixa, pois mesmo mobilizando diversos atores, as translações nem sempre concluem o ciclo de geração de mudança efetiva, não tendo força suficiente para manter a rede. Nesse sentido, a não simetria entre atores e a consequente não construção de subprogramas podem ser fatores que tiveram influência nesses resultados. Adicionalmente, foi possível consolidar a utilização da TAR como uma abordagem teórico-metodológica para compreensão das interações entre os agentes estudados.
Regimes de verdade na pandemia de Covid-19: discursos científicos e desinformativos em disputa no Youtube
Authors: Garcia Marcelo , Evangelista Cunha Simone , Oliveira Thaiane
Published: October 2021

Apesar dos esforços para combater a desinformação em meio a um cenário de infodemia, o YouTube tem sido um espaço proeminente para a circulação de boatos, fake news e desinformação relacionados a Covid-19. Este artigo tem como objetivo contribuir, a partir da observação de discursos circulantes na plataforma no Brasil ao longo de 2020, para a compreensão do processo de produção social de sentidos sobre a pandemia. Buscamos especificamente compreender as disputas pela produção de “verdades” entre narrativas imprecisas e contraditórias e discursos científicos. Adotamos procedimentos metodológicos mistos, combinando análise de redes sociais e análise de conteúdo, para identificar a teia de relações estabelecidas entre vídeos em circulação no YouTube a partir da combinação entre os termos "Sars-Cov 2", “coronavírus” ou “Covid-19” ao termo "verdade". Investigamos ainda de que forma a autoridade epistêmica é acionada em seis produções de maior destaque do universo coletado. Concluímos que as mediações algorítmicas da plataforma são relevantes para a popularização de discursos alternativos às instituições hegemônicas nas disputas discursivas sobre a pandemia. O levantamento também aponta para a relevância de signos e símbolos de autoridade epistêmica “tradicional”, que por vezes parecem substituir a apresentação de evidências científicas produzidas acerca da doença no período analisado.

A estrutura argumentativa do descrédito na ciência
Authors: Massuchin Michele Goulart , Tavares Camilla Quesada , Mitozo Isabele Batista , Chagas Viktor Henrique Carneiro de Souza
Published: October 2021

O ponto de partida da discussão é a desinformação e busca-se compreender um ponto mais específico que diz respeito à construção de um discurso de descrédito na ciência que se dá a partir da geração de desconfiança em relação às instituições científicas, do descrédito explícito de seus atores e discursos, e da elaboração de falas anticientíficas. Desse modo, o artigo busca analisar que elementos constituem a estrutura argumentativa que fortalece o discurso de descrédito na ciência que está associado à pandemia da COVID-19. Para tanto, trabalha-se com uma amostra dos conteúdos que circularam em 2020 em grupos de WhatsApp de apoio ao atual presidente da República. A partir de palavras-chaves ligadas à pandemia, uma amostra de 908 mensagens foi categorizada a partir da análise de conteúdo com base em dois eixos: a estrutura discursiva e de comunicação. Dentre os principais resultados, evidencia-se a construção do descrédito a partir do uso de elementos que dão legitimidade às mensagens, tanto no que tange à estrutura de comunicação, principalmente com links de sites, como na estrutura discursiva, com o uso de referências médicas e da própria ciência.

Personal Data and the Assemblage Security in Consumer Internet of Things
Authors: Ngoepe Mpho , Ngwenya Mfanasibili
Published: October 2021

The rise of the Internet of Things (IoT) has driven mobile applications development. As a result, in the consumer IoT (CIoT) space, any product usually comes with a smartphone application to either control, programme, or just view what is happening with the product. The IoT brings with it opportunities and challenges to consumers. For example, IoT technology makes it possible to connect all of a person’s devices to create a smart eco-system or assemblage. However, the biggest threat in CIoT is personal data security. This study utilized a qualitative narrative inquiry and Delphi technique to explore data security issues that come with CIoT assemblages and associated mobile applications in South Africa. The study established that consumers enjoy the convenience and benefits that IoT technology brings. It is concluded that for CIoT to thrive, safety is crucial, and all the stakeholders in the IoT assemblage need to ensure the protection of consumers.
Impact of Protection Level on Vertically-Differentiated Two-Sided Software Platforms
Authors: Hamedani Moez Farokhnia , Dehghan Ali
Published: October 2021

This paper studies the impact of software protection level on software platforms and customers’ responses to different levels of protection. This study models the interplay between users, developers and platforms, and the impact of quality degradation in the presence and absence of competitive platforms. All price structures are affected by protection level and quality degradation level for pirated copies of software. Customers, developers, and platform reaction to the protection and quality degradation levels can be contradictory, because an increase in those parameters may benefit one side, while hindering another. The results confirm that full protection against piracy is not always the best strategy in multisided platforms, but the impact of piracy changes under different scenarios.The results show that decisions regarding optimal security strategies should be taken in a systematic manner by incorporating the perspectives of all involved parties and the important factors extracted from the market within which the platform performs, such as monopoly or competition.
Achieving Reconciliation Between Privacy Preservation and Auditability in Zero-Trust Cloud Storage Using Intel SGX
Authors: Wu Liangshun , Cai Hengjin , Li Han
Published: October 2021

Cloud storage allows for saving files at an off-site location that is accessible through the public internet. However, cloud storage suffers from a lack of trust since employees have physical and electronic access to almost all of the data, and zero-trust security is thus essential. This paper proposes an SGX-based file hosting scheme that gives full consideration to both privacy preservation and auditability to address the aforementioned concerns. We designed a secure key exchange protocol consisting of two phases: a key generation phase and a key verification phase. Theoretical analysis and experiments indicate that the protocol can resist man in-the-middle attacks, which has been unattainable in previous studies. The experimental results show that our scheme takes little time regardless of file size and achieves solid performance in handling concurrent requests; furthermore, it is innocuous for clients, and the memory usage is acceptable.

Published: October 2021

Recommender systems are extensively used today to ease out the problem of information overload and facilitate the product selection by users in e-commerce market. Both privacy and security are two major concerns of the user in these systems. For the protection of the user’s rating, there are several existing works on the basis of encryption or randomization methodologies. This paper proposes a methodology that not only protects the privacy of ratings but also provides better accuracy. After applying fuzzification on the user ratings, random rotation and perturbation methods are used before being fed to the collaborative filtering system. In this process, similar users are grouped into clusters by which recommendation is made. By considering different cluster size on four different datasets, the proposed fuzzified k-Mode clustering method provides less MAE and RMSE value as compared to other k-Means and k-Mode clustering approach and also achieves the better privacy than randomized perturbation method by obtaining IVDM value i.e. 0.67, 0.61, 0.55 and 0.7.
Proxy-3S
Authors: Annane Boubakeur , Adel Alti
Published: October 2021

Virtualization plays a key role in the area of Mobile Cloud Computing (MCC). In MCC, the protection of distributed VMs and mobile users’ sensitive data, in terms of security and privacy, is highly required. This paper presents a novel cloud proxy known as Three Policies Secure Cloud Proxy (Proxy-3S) that combines three security policies: VM users’ access control, VMs’ secure allocation and VMs’ secure communication. The proposed approach aims to keep the distributed VMs safe in different servers on the cloud. It enhances the access authorization to permit intensive distributed application tasks on the cloud or mobile devices while processing and communicating private information between VMs. Furthermore, an algorithm that enables secure communication among distributed VMs and protection of sensitive data in VMs on the cloud is proposed. Several experiments were conducted using a real-world healthcare distributed application. The experiments achieved promising results for high-level data protection and good efficiency rating compared to existing works.
Intrusion Detection Model Using Temporal Convolutional Network Blend Into Attention Mechanism
Authors: Zhao Ping , Fan* Zhijie , Cao Zhiwei , Li Xin
Published: October 2021

In order to improve the ability to detect network attacks, traditional intrusion detection models often used convolutional neural networks to encode spatial information or recurrent neural networks to obtain temporal features of the data. Some models combined the two methods to extract spatio-temporal features. However, these approaches used separate models and learned features insufficiently. This paper presented an improved model based on temporal convolutional networks (TCN) and attention mechanism. The causal and dilation convolution can capture the spatio-temporal dependencies of the data. The residual blocks allow the network to transfer information in a cross-layered manner, enabling in-depth network learning. Meanwhile, attention mechanism can enhance the model's attention to the relevant anomalous features of different attacks. Finally, this paper compared models results on the KDD CUP99 and UNSW-NB15 datasets. Besides, the authors apply the model to video surveillance network attack detection scenarios. The result shows that the model has advantages in evaluation metrics.

Published: October 2021

In recent years, 5G has been the focus of research and development in the telecom industry. This paper aims to understand the development trend and technical hot spots of 5G technology through the patent analysis and build a citation network at the assignee organization level. The workflow of the paper is divided into four steps: patent data collection and cleaning, patent overview analysis, network creation and analysis, O-I index analysis. This article collected the patent data from the United States patent and trademark office (USPTO). We understand the application trend, technical hot spots, and leading players in the 5G domain through the patent overview analysis. We comprehend the structure and characteristics of the network and critical nodes from network topology analysis. By using O-I index analysis, we learn the flow of 5G technology knowledge between the organizations. This paper provides a useful analytical model for the patent analysis and technological knowledge flow in a specific field, which can be applied to patent analysis in other fields.

This project aims to model the kinetic controls on sulphide composition due to the extraction of chalcophile elements from silicate magmas, and use the numerical models to deepen our knowledge of the physical constraints that govern sulphide dynamic processes
(e.g., breakup, coalescence, transport and deposition) in magmatic system. Based on the new understanding obtained from these forward models, we then take the textural and compositional features of sulphide globules from the field investigation at Raglan komatiite-associated deposits for instance,
to better understand the control on entrainment, transport and deposition of sulphide liquids within the ore-forming processes.
Evaluating white mica as an indicator mineral for lithium bearing pegmatites, Wekusko Lake pegmatite field, Manitoba, Canada
Authors: Benn D , Linnen R , Martins T
Published: October 2021

This project investigates the potential use of white micas as an indicator mineral within Li-bearing pegmatites and the potential of field portable techniques, such as Raman spectroscopy and Laser Induced Breakdown Spectroscopy (LIBS) as real-time techniques in
exploration. The pegmatites in the Wekusko Lake field, Manitoba, Canada, display five zones of varying mineralization. White micas display two textures in the field (primary igneous and secondary) and four textures were identified by backscattered electron imaging (poor zonation, rimmed, patchy and
exsolution). The white micas were analysed by Electron Probe Micro-Analysis (EPMA) and Laser Ablation Induction-Coupled Plasma Mass Spectroscopy (LA-ICP-MS) and the results show a strong correlation in the Li content of the white mica and the whole rock Li2O obtained from the assays of drill core.
The K/Rb vs. Cs contents of the white mica indicate that the most prospective dikes contain moderate to highly evolved grains. The use of portable Raman Spectrometer, while useful for mineral identification, was not able to detect a significant Li signature at the concentrations tested (1500-6000
ppm).
