The Impact of Macroeconomic News on US Interest Rates and Stock Indices Conditional on Their Volatility
Authors: Tuysuz Sukriye , Lubochinsky Catherine
Published: September 2019

This paper investigates the impact of macroeconomic news on the dynamics of interest rates and stock returns during "low" and "high" volatility periods. These periods are determined by estimating asset dynamics using a SWARCH process. Our results suggest that securities volatility is higher during periods of financial or economic instability. We use these results to evaluate the impact of news during "low" and "high" volatility  periods using a GARCH model. News effects, especially “good” and “large” news, on interest rates are amplified during "high" uncertainty periods. The effect on stock returns is moderate. GARCH parameters differ strongly during both periods.

Authors: Nizeyimana Jean D’amour
Published: September 2019

Rail transport around the world is developing very fast. There is no doubt that in the future it will be one of the most used transportation means. Different forms of railway transport have been used since its birth such as steam locomotives, Diesel electric locomotive, electric locomotives and Magnetic levitation (MAGLEV) trains. This paper aims at reducing power consumption in auxiliary system of Electric locomotives which use electrical power as a prime mover by producing electricity through train motion. Simulation in Matlab is done whereby a permanent magnet DC motor is attached to train wheel axle and with the relative motion of the rotor in the magnetic field of the permanent magnet stator produced by rotation of axles generate electricity which is stored in batteries and then supplied to auxiliary system of the train. The simulation of the system demonstrated that electricity produced is enough to power the auxiliary system, hence reducing power consumption by the train.

Authors: Rahmani Ali Mohammad , Noori Abdul Ghani
Published: September 2019

Life Cycle Assessment (LCA) of current MSWMS for Kandahar City and two developed integrated waste management systems (IWMSs) were carried out. In addition, field survey was performed to find out the composition of MSW in Kandahar City as this was the base line data for the LCA’s. Field survey at the MSW disposal site of Kandahar City revealed that physical composition of food waste was low (26.89%) and inert (soil, sand, brick, etc.) was high (39.72%) because of constructional activities, and street and canal cleaning. LCA of current MSWMS was carried out with inclusion of fuel energy production, transport, burning used engine oil obtained from vehicles maintenance, and MSW degradation in its system boundary. The result showed that environmental impact potential for global warming, ozone depletion, terrestrial acidification, freshwater eutrophication, human toxicity, photo oxidant formation and particulate matter formation were 1504.6 kg CO2 equivalent, 13 g CFC-11 equivalent, 1.11 kg SO2 equivalent, 645 mg P equivalent, 28.77 kg 1,4-DB equivalent, 0.46 kg C2H4 equivalent plus 2.11 kg NMVOC, and 0.55 kg PM10 equivalent, respectively, per functional unit (FU). MSW degradation and transport were the processes mostly contributing to potential environmental impact. In scenario 1, recycling (RC) avoided energy and raw materials consumption for new production. It could reduce 10.6% (159.3 kg CO2 equivalent) global warming potential (GWP) compared to base scenario. In scenario 2, in spite of recycling, anaerobic digestion was included to recover energy and compost. Scenario 2 showed reduction of 32.6% (490 kg CO2 equivalent) GWP compared to base scenario. Hence, scenario 2 was a better IWMS in term of environmental sustainability to be considered by decision makers in Kandahar City.

Authors: Afe Abayomi Joseph , Onyema Maduakolam , Ojoye Adewunmi O , Iwuoha Esther
Published: September 2019

Background: Key populations are defined groups who, due to specific higher-risk behaviour, are at increased risk of HIV infection irrespective of the epidemic type or local context. Also, they often have legal and social issues related to their behaviour that increase their vulnerability to HIV. In Nigeria, Key population (KP) groups account for a significant portion of new HIV infections. Directly, FSW, MSM and PWID, who constitute an estimated 1% of the adult Nigerian population, contribute nearly 23% of new HIV infections. About 20% of infections may be attributed to female sex workers, their clients and client partners alone, of which three-fourths may be attributable to brothel-based FSWs. People who inject drugs (PWID), MSM and their partners respectively contribute about 9% and 10% of the annual new infections. These KPs and their partners together, who constitute an estimated 3.4% of the adult population, contribute as much as 40% of new infections

Methods: This was a retrospective analysis of the programmatic data of an HIV intervention projects among the three key populations in 15 local government areas (LGA) in Lagos, Nigeria, between October 2018 and June 2019.

Findings:  Among the MSM, HIV positivity rate was 9.6 %      (2.9% to 15.2%), about 96% were linked and initiated on antiretroviral drugs (ARV). Six months   ART retention rate was 95%. For the FSW, the  HIV infection rate was  of 5% (1.4% -12.9%) and   a linkage and ART initiation  rate was  96.5% while  the  six month ART retention rate was 92% . Among the   male PWID the HIV positivity rate was 1.4%. (0.4%- 17.3%) while the female PWID   HIV positivity rate was 8.14%, which was 8 times the average positivity rate among the male PWID. Linkage and ART initiation rate was 100% among HIV positive PWID but only 50% were still active in care 6months after initiation (ART retention rate).    

Conclusions: Having attained   over 90% ARV initiation and retention rates among MSM, FSW and PWID on the project, achieving the 3rd UNAIDS target of 90% viral suppression in the groups is very much possible with appropriate programming. Also engaging social support service such as the use of peers as case managers is associated with excellent   6 month retention outcome.

Saat ini pembinaan terhadap koperasi yang ada di lingkungan Pemerintah Kabupaten Kotawaringin Timur sangat diperlukan karena adanya koperasi yang baru berdiri maupun yang telah lama berdiri kinerjanya menurun yaitu omset koperasi turun sebesar 30% dan lambat dalam melaksanakan Rapat Anggota Tahunan (RAT) yaitu pada tahun 2016 sebanyak 164 koperasi dan tahun 2017 sebanyak 140 koperasi. Dengan jumlah koperasi saat ini Dinas Koperasi kekurangan SDM pembina, oleh karena itu perlu menentukan koperasi yang diprioritaskan mendapatkan pembinaandengankriteria yaitu jenis koperasi, masa kerja, kategori, jumlah anggota, modal sendiri, volume usaha, dan SHU. Dinas Koperasi dan UKM Kabupaten Kotawaringin Timur melakukan pembinaan dengan bimbingan teknis terhadap koperasidan audit terhadap kepengurusan dan keuangan Koperasi, namun karena belum adanya pedoman dalam menentukan koperasi yang layak untuk dilakukan pembinaan sehingga sering mengakibatkan salah sasaran dalam memilih koperasi yaitu koperasi yang seharusnya mendapat pembinaan tetapi tidak dilaksanakan pembinaan.. Salah satu cara untuk mengatasi permasalah tersebut adalah dengan Data Mining dengan metode klasifikasi menggunakan algoritma K-Nearest Neighbour (K-NN). Penelitian ini menerapkan algoritma K-NN dalam menentukan koperasi yang layak mendapatkan pembina. Hasil yang dari penelitian ini adalah klasifikasi koperasi yang layak mendapatkan pembinaan dengan akurasi yang diperoleh sebesar 96,33%.Kata Kunci — Pembinaan, Klasifikasi, KNNCurrently coaching of cooperatives in Kotawaringin Timur District is very necessary because the existence of cooperatives that established and have long been established, their performance has decreased, namely the turnover of cooperatives fell by 30% and slow in carrying out the RAT, namely in 2016 as many as 164 cooperatives and in 2017 there were 140 cooperatives. Cooperatives currently the Department of Cooperatives is lacking in human resources, it is therefore necessary to determine which cooperatives are prioritized to get guidance with criteria such as type of cooperative, length of service, category, number of members, own capital, business volume, and SHU. Cooperative District conducts coaching with technical guidance on cooperatives and audits of Cooperative management and finance, but due to the lack of guidelines in determining appropriate cooperatives for coaching that often results in mis-targeting in choosing cooperatives, namely cooperatives that should receive guidance but not coaching is carried out. One way to overcome these problems is by Data Mining using a classification method with K-Nearest Neighbor (K-NN) algorithm. This study applies the K-NN algorithm in determining cooperatives that are eligible for guidance. The results is with an accuracy of 96.33%.Keywords — Coaching, Classification, KNN

Ex situ conservation storage potential of Saxifraga cernua (Saxifragaceae) bulbils from alpine species
Authors: Breman Elinor , Détraz-Méroz Jacqueline , Terry Janet , Lambelet Catherine
Published: September 2019

In high latitude and alpine environments many plants show an increase in viviparous reproduction in response to harsh environmental conditions. Low or no seed set means that ex situ conservation in the form of seed banking is not a conservation option for such species. We investigated the potential for bulbils to be stored ex situ in seed banks using traditional storage methods (drying and freezing at −20 °C) and cryopreservation (drying and freezing at −180 °C) as a means of ensuring the long-term conservation of such species. In addition, the impact of drying bulbils to 15% eRH or maintaining initial humidity (60% eRH) was investigated. The study was based on bulbils of the drooping or nodding saxifrage (Saxifraga cernua) collected in Bellalui (commune d’Icogne, Switzerland) at an altitude of 2200 m.a.s.l. Our findings suggest that conservation under traditional seed banking methods or by cryopreservation is a viable option for species producing small (<2 mm) bulbils. This provides new hope for conserving high altitude or latitude plants producing bulbils.
NANOTECNOLOGIA E SUA REGULAMENTAÇÃO NO BRASIL
Authors: Hupffer Haide Maria , Lazzaretti Luisa Lauermann
Published: September 2019

RESUMOO presente estudo objetiva contextualizar a formação de um conceito para nanotecnologias, suas potencialidades, seus benefícios e examinar a legislação brasileira sobre nanotecnologia e as propostas do legislativo para sua regulamentação. O estudo é de caráter exploratório e descritivo com apoio no método sistêmico-construtivista para contextualizar as nanotecnologias no sistema econômico e no sistema do Direito, seus riscos e benefícios. A pesquisa aponta que não há uma regulação específica para as nanotecnologias no Brasil, a exemplo da maioria dos países. Regular as nanotecnologias é um dos maiores desafios do sistema político, jurídico e econômico, considerando as peculiaridades das características físico-química dos nanomateriais, seus potenciais riscos e seu interesse comercial. A nível mundial, observa-se que organizações internacionais privadas implementaram estratégias de autorregulação mais voltadas para boas práticas e que desempenham uma função importante na regulação das nanotecnologias, as quais, mesmo tendo aplicações volitivas pelas empresas e pelos governos, são bem aceitas por eles e bem vistas pelos consumidores.Palavras-chave: Nanotecnologia. Regulamentação. Autorregulação. ABSTRACTThe present study aims to contextualize the formation of a concept for nanotechnologies, their potentialities, their benefits and to examine the Brazilian legislation on nanotechnology and the legislative proposals for its regulation. The study is exploratory and descriptive with support of the systemic-constructivist method to contextualize nanotechnologies in the economic system and in the legal system, its risks and benefits. The research points that there is not a specific regulation for nanotechnologies in Brazil, such as most countries. Regulating nanotechnologies is one of the major challenges of the political, legal and economic system, considering the peculiarities of the nanomaterials’ physico-chemical characteristics, their potential risks and their commercial interest. At the global level, it is possible to observe that private international organizations have implemented self-regulation strategies more focused on good practices, and, that has an important role in nanotechnologies’ regulation, which, even if it is volitional applied by companies and governments, it is well accepted by them and well seen by the consumers.Keywords: Nanotecnologia.

Tecnologias digitais no ensino de línguas
Authors: MENEZES Vera
Published: September 2019

Este texto apresenta a história da aprendizagem de línguas mediada por computador no Brasil, discutindo experiências passadas e atuais e fazendo previsões para o futuro. O artigo mostra que a proposta de Warschauer (1996) de três fases para a história de do uso de tecnologias no ensino de línguas (behaviorista, comunicativa e integrativa) não é adequada para descrever o que aconteceu no Brasil por causa da chegada tardia dos computadores nas escolas. Também demonstra que o interesse pelas tecnologias digitais tem crescido e tem havido um aumento expressivo de publicações neste campo em livros e edições especiais de periódicos. Após as previsões para o futuro do uso de tecnologia, o texto conclui que não há necessidade de apagar práticas antigas, mas eficientes. No entanto, é preciso haver engajamento em novas formas de aprender e ensinar, de interagir e de criar conhecimento.

Authors: Rohrmann Carlos Alberto , Cunha Ivan Luduvice
Published: September 2019

Este artigo, tendo como marco teórico a tese Code and Other Laws of Cyberspace, de Lawrence Lessig, tem como objetivo examinar a política de recadastramento biométrico promovida pelo Tribunal Superior Eleitoral, especificamente quanto ao direito constitucional ao voto secreto. Para tanto, utilizando o método indutivo e a pesquisa bibliográfica de livros e artigos científicos publicados em periódicos nacionais e estrangeiros, confirma a hipótese da existência de risco ao direito fundamental ao voto secreto causado pelo recadastramento biométrico de eleitores promovido pelo Tribunal Superior Eleitoral, demonstrando que a tecnologia de votação eletrônica é passível de fraudes porque expõe importantes dados pessoais e eleitorais. A pesquisa conclui que apenas uma total desvinculação da máquina que identifica o eleitor com a máquina que registra o voto pode garantir a proteção da escolha feita pelo eleitor.

Published: September 2019

A semiótica e o turismo têm uma relação próxima visto que se preocupam com a comunicação e, a interseção entre os dois campos de saber tem sido discutida mundo afora quer focando na análise da viagem perfeita, na significação cultural da viagem ou no olhar semiótico do turismo. Este trabalho considerou acessar a comunicação no turismo a partir da marca turística, assim o objetivo é apresentar o uso da semiótica como metodologia para investigar a comunicação no turismo, por meio de sua aplicação no estudo da Marca Turística España. A metodologia foi dividida em três etapas: a) análise semiótica baseada na corrente peirceana (tripartição do signo) e por meio do aporte teórico dos trabalhos de Santaella (2015), b) focus group com estudantes de pós-graduação e c) questionário on-line. Os instrumentos foram aplicados de forma complementar e sucessiva e, apesar da separação das etapas e dos instrumentos, todas tiveram a semiótica como um fio condutor, isto é, cada um dos instrumentos também teve uma contribuição da semiótica em sua elaboração e aplicação. Como resultados podemos destacar o entendimento da aplicabilidade da semiótica em torno dos signos e significados presentes no turismo, e o entendimento do processo de comunicação turística por meio das marcas, uma vez que, os signos presentes nas marcas desempenham uma função mediadora entre o eu-turista e a realidade do turismo. Outra contribuição teórica esta relacionada à compreensão da semiótica como integrante do arcabouço para uma epistemologia do turismo, a partir de uma base interpretativista e como uma metodologia de análise qualitativa do turismo enquanto fenômeno comunicacional. Dessa forma cabe observar que os resultados deste estudo não se findam na análise apresentada, visto que a intenção não foi replicar um conhecimento já existente, mas contribuir para o avanço do conhecimento ao aproximar os campos da semiótica e do turismo.

Counts data models cope with the response variable counts, where the number of times that a certain event occurs in a fixed point is called count data, its observations consists of non-negative integers values {0,1,2,…}. Because of the nature of count data, the response variables are usually considered doing not follow normal distribution. Therefore, linear regression is not an appropriate method to analysis count data due to the skewed distribution. Hence, using linear regression model to analysis count data is likely to bias the results, under these limitations, Poisson regression model and “Negative binomial regression” are likely the appropriate models to analysis count data. Sometimes researchers may Counts more zeros than the expected. Count data with many Zeros leads to a concept called “Zero-inflation”. Data with abundant zeros are especially popular in health, marketing, finance, econometric, ecology, statistics quality control, geographical, and environmental fields when counting the occurrence of certain behavioral and natural events, such as frequency of alcohol use, take drugs, number of cigarettes smoked, the occurrence of earthquakes, rainfall, and etc. Some models have been used to analyzing count data such as the “zero- altered Poisson” (ZAP) model and the “negative binomial” model. In this paper, the models, Poisson, Negative Binomial, ZAP, and ZANB were been used to analyze rainfall data.
Jaccard Coefficients based Clustering of XML Web Messages for Network Traffic Aggregation
Authors: Al-Shammary Dhiah
Published: September 2019

This paper provides static efficient clustering model based simple Jaccard coefficients that supports XML messages aggregator in order to potentially reduce network traffic. The proposed model works by grouping only highly similar messages with the aim to provide messages with high redundancy for web aggregators. Web messages aggregation has become a significant solution to overcome network bottlenecks and congestions by efficiently reducing network volume by aggregating messages together removing their redundant information. The proposed model performance is compared to both K-Means and Principle Component Analysis (PCA) combined with K-Means. Jaccard based clustering model has shown potential performance as it only consumes around %32 and %25 processing time in comparison with K-Means and PCA combined with K-Means respectively. Quality measure (Aggregator Compression Ratio) has overcome both benchmark models
Robust logistic regression in the presence of high leverage points
Authors: Mohammed Mohammed A.
Published: September 2019

In this article we conceder the logistic regression model with high leverage points. For the logistic regression model with a binary response, we suggested a new robust approach called robust logistic regression (RLR) based on the robust mahalanobis distance (RMD) which depends on the minimum volume ellipsoid (MVE) estimators. The RMD is computed by using the algorithm of stochastic gradient descent (SGD). In order to assist the new suggested approach we compare it with some existing method such as maximum likelihood estimator and robust M-estimator in logistic regression model. The simulation study points that the RLR has supreme performances throw some measurement comparison.
Review of Joanna Bocheńska (ed.), Rediscovering Kurdistan’s Cultures and Identities: The Call of the Cricket
Authors: Marilungo Francesco
Published: September 2019

The academic field of Kurdish studies has experienced considerable growth in recent years. Compared to the later decades of the 20th century that were characterized by the scarcity and scattering of resources and researches on Kurdish subjects, today one can find an ever-growing variety of studies in international languages to satisfy his/her own curiosity on this matter. Recent political developments in the region (i.e. the involvement of Kurdish groups in the resistance against the ISIS, the relative self-determination of the Kurds in Syria, the resurgence of armed conflict in Turkey since 2015 after the failure of the so-called “peace process”, and the referendum on the independence of Iraqi Kurdistan in 2017) have raised academic interest and increasingly put the Kurds on the world agenda. By itself, this can be heralded as a positive development in Middle Eastern studies at large; however – and this is the main argument and the foundational stance the of the book here reviewed – this recent attention has been predominantly structured along narratives of “conflict and resistance” that often prevent us from seeing other aspects of Kurdish culture and society. Indeed, the amount of academic production related to the Kurdish culture at large is significantly, and perhaps disproportionately, lower than that regarding geopolitical, political and military aspects. Nevertheless, now – in the nick of the time – the volume entitled Rediscovering Kurdistan’s Cultures and Identities: The Call of the Cricket has emerged with the aim of counterbalancing the above disproportion.

En la biznaga ‘barril azul’ (Ferocactus glaucescens (DC.) Britton y Rose) se evaluaron 12 tratamientos considerando concentraciones nutritivas (100, 200, 400 y 800 mg L-1) de fertilizantes solubles en interacción con tres niveles de nitrógeno (N), fósforo (P) y potasio (K) (100-50-50, 100-50-100 y 50-50-100), éstos fueron comparados con la solución nutritiva de Steiner al 25% y 50% y dos testigos comerciales (triple 17 y triple 20). Las variables evaluadas fueron altura de la planta, diámetro de tallo, peso fresco y seco del tallo y raíz, y concentración de N, P y K. Se realizó un ANOVA y una prueba de medias de Tukey (p≤ 0.05) que indican que la solución nutritiva Steiner al 50% y la solución elaborada con 800 mg L-1 con el balance de 100-50-100 de NPK generaron a los 153 DDT plantas con mayor biomasa y tamaño comercial con altura y diámetro de tallo superior a 6 cm refiriendo que en etapas tempranas la relación N:K influyen en este proceso.

El tinguaraque (Solanum lycopersicum var. Cerasiforme), frutilla silvestre semejante al jitomate, crece en bosques de encino, zonas perturbadas y terrenos cultivados. Su fácil desarrollo en diferentes condiciones, junto con un sabor acidulado y su pequeño tamaño, hacen un producto más atractivo que el jitomate comercial. Este trabajo caracterizó fisicoquímicamente frutos de tinguaraque y comparó la respuesta con jitomate cherry, ambos en invernadero, como un primer paso para su mejora e incorporación en la dieta del humano. En agosto y septiembre de 2017, se colectaron plantas silvestres de tinguaraque (JT) para obtener semillas, mismas que se germinaron junto con semillas de jitomate cherry (JC) en invernadero Entre los parámetros evaluados se registró: patrón de crecimiento de plantas, peso y producción de frutos maduros, para los análisis fisicoquímicos se siguió la metodología de la AOAC registrando sabor, aporte energético, extracto etéreo, proteína cruda, humedad, materia seca y cenizas, entre otros. La información se analizó con Anova y las diferencias se obtuvieron mediante la prueba de Tukey a un α= 0.05. La dulzura destacó al cultivar JT en invernadero en comparación con JC (13.4 ±0.5 y 7.6 ±0.8 °Brix) y fue ligeramente mayor en pH respecto a JC (4.3 ±0.1 y 4.1 ±0.1). Asimismo, JT en comparación a JC registró valores similares en cuanto a proteína (17.5 ±2.2 y 16.6 ±0.6%) y contenido energético (5.1 ±0.4 y 4.9B ±0.1 kcal g-1 MS, respectivamente). Estos atributos de calidad pueden posicionar
