Quantitative identification of pseudofaults underlying igneous rocks through wave-equation-based velocity modeling: A case study of the Shuntuoguole uplift, Tarim Basin, China
Authors: Jiang Ziran , Sun Yuefeng , Liu Shugen , Lin Kai
Published: January 2019

Fault identification plays an important role in oil and gas exploration of the Ordovician reservoirs underlying the Permian igneous rocks in the fault-controlled Shuntuoguole uplift, Tarim Basin, China. Faults identified through conventional analysis of seismic coherence attributes, however, usually contain many artifacts or pseudofaults in which velocities of the igneous rocks tend to be selected incorrectly during migration imaging. We have evaluated a quantitative method to identify the pseudofaults by numerical simulation of depth migration on synthetic seismic records generated by finite-difference modeling of wave propagation. Detailed information on the spatial distribution and velocity range of the Permian igneous rocks is used to build a refined velocity model for the wave-equation-based forward modeling, calibrated with core, well log, and seismic data. It is found that the thickness and the migration velocity error used for the igneous rocks in depth migration are important factors affecting the pseudofault throws. There exists a strong quantitative relationship between igneous rock thickness ([Formula: see text]) and pseudofault throw ([Formula: see text]), [Formula: see text], where [Formula: see text], [Formula: see text], and [Formula: see text] are constants for a given migration velocity error. For a maximum migration velocity error of 15% for the dacite bodies in the studied area, [Formula: see text], [Formula: see text], and [Formula: see text] are 0.0002, 0.1864, and [Formula: see text], respectively. Using this relationship, the maximum fault throw ([Formula: see text]) of a pseudofault caused by an arbitrary thickness of any dacite body can be calculated. If the actual fault throw (H) of an apparent fault measured on the migrated seismic profile is greater than the calculated maximum fault throw for the fault, i.e., [Formula: see text], then the apparent fault is a real geologic fault. Otherwise, it is a pseudofault. The method has been successfully applied to produce corrected fault distribution maps for geologic evaluation of the Ordovician reservoirs in the Shuntuoguole region.
A neurodevelopmental TUBB2B β-tubulin mutation impairs Bim1 (yeast EB1)-dependent spindle positioning

Published: January 2019

Malformations of the human cerebral cortex can be caused by mutations in tubulins that associate to compose microtubules. Cerebral cortical folding relies on neuronal migration and on progenitor proliferation partly dictated by microtubule-dependent mitotic spindle positioning. A single amino acid change, F265L, in the conserved TUBB2B β-tubulin gene has been identified in patients with abnormal cortex formation. A caveat for studying this mutation in mammalian cells is that nine genes encode β-tubulin in human. Here, we generate a yeast strain expressing F265L tubulin mutant as the sole source of β-tubulin. The F265L mutation does not preclude expression of a stable β-tubulin protein which is incorporated into microtubules. However, impaired cell growth was observed at high temperatures along with altered microtubule dynamics and stability. In addition, F265L mutation produces a highly specific mitotic spindle positioning defect related to Bim1 (yeast EB1) dysfunction. Indeed, F265L cells display an abnormal Bim1 recruitment profile at microtubule +ends. These results indicate that the F265L β-tubulin mutation affects microtubule +end complexes known to be important for microtubule dynamics and for microtubule function during mitotic spindle positioning.

Published: January 2019

Islet inflammation and cytokine production are implicated in pancreatic β-cell dysfunction and diabetes pathogenesis. However, we lack therapeutics to protect the insulin-producing β-cells from inflammatory damage. Closing this clinical gap requires the establishment of new disease models of islet inflammation to facilitate screening efforts aimed at identifying new protective agents. Here, we have developed a genetic model of Interleukin-1β (Il-1β)-driven islet inflammation in zebrafish, a vertebrate that allows for non-invasive imaging of β-cells and in vivo drug discovery. Live imaging of immune cells and β-cells in our model revealed dynamic migration, increased visitation and prolonged macrophage retention in the islet, together with robust activation of NF-κB signalling in β-cells. We find that Il-1β-mediated inflammation does not cause β-cell destruction but, rather, it impairs β-cell function and identity. In vivo, β-cells exhibit impaired glucose-stimulated calcium influx and reduced expression of genes involved in function and maturity. These defects are accompanied by α-cell expansion, glucose intolerance and hyperglycemia following a glucose challenge. Notably, we show that a medicinal plant derivative (wedelolactone) is capable of reducing the immune-cell infiltration while also ameliorating the hyperglycemic phenotype of our model. Importantly, these anti-diabetic properties in zebrafish are predictive of wedelolactone's efficacy in protecting rodent and human islets from cytokine-induced apoptosis. In summary, this new zebrafish model of diabetes opens a window to study the interactions between immune and β-cells in vivo, while also allowing the identification of therapeutic agents for protecting β-cells from inflammation.
Simple Colorimetric Analysis for Determining Hexavalent Chromium with High Sensitivity via Homogeneous Liquid-Liquid Extraction
Authors: Yokota Yuki , Manaka Atsushi , Tafu Masamoto , Kato Takeshi , Tomita Keiichi , Akazawa Toshiyuki
Published: January 2019

Colorimetric analysis with diphenylcarbazide has been used as a simple method to determine hexavalent chromium (Cr(VI)). However, the low sensitivity of this technique makes it difficult to determine concentrations close to the environmental standard value (0.05 mg/L). We found that the phase separation phenomenon produced a small amount of the extraction phase when a mixture of 2-propanol and a small amount of dimethyl phthalate were added to a water sample, and that the Cr(VI)-diphenylcarbazide complex was extracted into this phase with high efficiency. Based on these findings, we report a simple method for colorimetric analysis for determining Cr(VI) with high sensitivity via homogeneous liquid-liquid extraction using water, 2-propanol, and dimethyl phthalate. As a result, the extraction percentage for Cr(VI) was 88% and the concentration factor improved up to 121-fold (27.4 mL → 226 µL). Using the proposed extraction method, determination limit (10σ) and detection limit (3σ) were 0.11 ppb and 0.03 ppb, respectively. This method can be employed for the determination of hexavalent chromium in groundwater systems by the use of EDTA as masking agent.
Development of Supported NiO Nanocluster for Aerobic Oxidation of 1-Phenylethanol and Elucidation of Reaction Mechanism via X-ray Analysis
Authors: Sasaki Takuro , Devred François , Eloy Pierre , Gaigneaux Eric M , Hara Takayoshi , Shimazu Shogo , Ichikuni Nobuyuki
Published: January 2019

Supported NiO nanocluster catalysts were synthesized by using Ni colloid as a precursor and applied to the aerobic oxidation of 1-phenylethanol. Obtained catalysts were characterized through X-ray absorption fine structure (XAFS), X-ray photoelectron spectroscopy (XPS) and in situ X-ray diffraction (XRD). Activated carbon (AC) supported NiO nanocluster catalyst showed catalytic activity toward the aerobic oxidation of 1-phenylethanol without any additives. Only the AC support allowed the NiO catalyst to be active although other supports did not. XAFS and in situ XRD revealed that NiO nanocluster was fixed on the supports successfully. XAFS and XPS gave information about differences in the local structure, chemical state and electronic state of Ni among the different supports. The obtained catalyst showed activity more effectively compared to conventional nickel-based catalysts.
The MRI characteristics of non-mass enhancement lesions of the breast: associations with malignancy
Authors: Aydin Hale
Published: January 2019

Objective:

The American College of Radiology updated the terms used for expressing the imaging characteristics of non-mass enhancement (NME) lesions in the fifth edition of the breast imaging-reporting data system (BI-RADS) lexicon. Both the distribution and internal enhancement descriptors were revised for NME lesions. Our aim was to determine the MRI characteristics of NME lesions and to investigate their association with malignancy.

Methods:

The MRI results of 129 NME lesions were retrospectively evaluated. The medical files, biopsy results and follow-up findings of lesions were recorded. Patients who had benign biopsy and those who had stable or regressed lesions during follow-up were classified as benign. All MRI results had been obtained with a 1.5 Tesla Signa HDx MR system (GE Healthcare).

Results:

Segmental and diffuse distribution along with clustered-ring internal enhancement were significantly associated with malignancy, while linear distribution and homogeneous enhancement pattern were associated with benignancy. Additionally, the plateau type (Type II) curve was significantly more frequent in malignant lesions. There was no association between the presence of cystic structures and the benign/malignant nature of the lesion. However, multivariate logistic regression showed that only segmental distribution and diffusion restriction were associated with malignancy.

Conclusion:

In the current study, segmental distribution, clustered-ring enhancement, Type II dynamic curve and the presence of diffusion restriction were found to be associated with malignancy. There is a requirement for multicenter studies which include higher numbers of patients in order to better evaluate lesions with rarer characteristics for distribution and enhancement pattern.

Advances in knowledge:

Our aim in this study was to investigate the MRI characteristics of NME lesions. We have reported the MRI findings of NME lesions and have found that segmental distribution and clustered-ring enhancement patterns are significantly more frequent in malignant lesions.
Key Concepts for assessing claims about treatment effects and making well-informed treatment choices
Authors: Oxman Andrew David , Chalmers Iain , Austvoll-Dahlgren Astrid ,   Informed Health Choices group
Published: January 2019

Background: The Informed Health Choices (IHC) Key Concepts are standards for judgement, or principles for evaluating the trustworthiness of treatment claims and treatment comparisons (evidence) used to support claims, and for making treatment choices. The list of concepts provides a framework, or starting point, for teachers, journalists and other intermediaries for identifying and developing resources (such as longer explanations, examples, games and interactive applications) to help people to understand and apply the concepts. The first version of the list was published in 2015 and has been updated yearly since then. We report here the changes that have been made from when the list was first published up to the current (2018) version.

Methods: We developed the IHC Key Concepts by searching the literature and checklists written for the public, journalists, and health professionals; and by considering concepts related to assessing the certainty of evidence about the effects of treatments. We have revised the Key Concepts yearly, based on feedback and suggestions; and learning from using the IHC Key Concepts, other relevant frameworks, and adaptation of the IHC Key Concepts to other types of interventions besides treatments.

Results: We have made many changes since the Key Concepts were first published in 2015. There are now 44 Key Concepts compared to the original 32; the concepts have been reorganised from six to three groups; we have added higher-level concepts in each of those groups; we have added short titles; and we have made changes to many of the concepts.

Conclusions: The IHC Key Concepts have proven useful in designing learning resources, evaluating them, and organising them. We will continue to revise the IHC Key Concepts in response to feedback. We welcome suggestions for how to do this.

Published: January 2019

Background: Critical congenital heart disease (CCHD) make up a group of heart diseases present in newborns since the prenatal period and requiring early intervention through surgery or percutaneous interventions in the first year of life. Little is known about the societal economic impact associated with their care in low to middle income countries. We estimated direct medical costs, out-of-pocket expenditures and indirect costs of CCHD patients in Colombia.

Methods: The methodology to estimate costs involved four stages: identification, measurement, and assessment of resources consumed, and total cost calculation. Regarding medical costs, hospital and ambulatory costs were estimated for the patient’s first year of life using clinical records of 73 patients and with thematic experts. A survey was carried out on 20 children´s caregivers to determine the out-of-pocket expenses and indirect costs. For this estimation, a descriptive analysis was made on the survey taking into account the reported salary. All costs are expressed in US dollars (2017 exchange rates).

Results: The average direct medical hospital costs for CCHDs were $25,835 and the ambulatory costs reached $480. Indirect costs were $1,303 and out-of-pocket expenses were $2,058, which for families with an income lower than one monthly minimum wage (1 SMMLV) in 2017 correspond to $250. The impact on their budget was 57%.

Conclusions: CCHDs represent an important economic impact both for the Colombian General Social Health System and for families. This study made it possible to estimate the costs that are not easily visible and thus quantified.
Elementos para una caracterización marxista del neoliberalismo
Authors: Espinoza Carrasco Daniel
Published: January 2019

Según diversas caracterizaciones del neoliberalismo, este es una ideología económica que se materializa en un plan de gobierno cuyo objetivo es el libre mercado. El problema de dichas nociones radica en su ambigüedad y en pensar el neoliberalismo a partir de lo que este sostiene de sí mismo. La tesis central de este artículo es que elneoliberalismo es un fenómeno eminentemente político, lo que remite específicamente al Estado. Con los conceptos que aporta la teoría marxista de Poulantzas se da uenta de una función y de las relaciones que el Estado sostiene con una formación social. Lo anterior permite interpretar los cambios sociales acontecidos a partir de la irrupción de gobiernos neoliberales y sus reformas, estableciendo una base sobre la que se describen las particularidades del Estado neoliberal y sus diferencias con otras formas de Estado. En este punto, la noción de acumulación por desposesión aporta elementos clave para entender cómo opera el neoliberalismo.
Religión e identidad. La amenaza del Estado Islámico en Irak y Siria
Authors: Ospina Morales Guillermo
Published: January 2019

Las acciones del Estado Islámico en el norte de Irak representaron una amenaza existencial para los diferentes grupos societales que habitaban los territorios que quedaron en manos del autodenominado califato. Sin embargo, sus acciones no son violencia sin sentido, irracionalidad o sevicia. Estas son parte de la concepción salafista, la cual señala que el islam se encuentra en peligro existencial por lo que la violencia contra las minorías es considerada necesaria para la defensa del monoteísmo (tawhid) y para la lucha contra el politeísmo (shirk) y los infieles (kuffar). De este modo, el presente artículo analiza cómo la securitización de la religión que realiza el Estado Islámico representa una amenaza para los grupos minoritarios en Irak y Siria.
A política social do Governo Chávez: quais os avanços? | The social policy of the Chávez Government: what advances?
Authors: FUKUSHIMA KÁTIA ALVES
Published: January 2019

O governo Chávez (1999-2013) situou-se em um processo de rupturas com o sistema político vigente até 1998, constituindo-se em um novo bloco no poder, em que o presidente Chávez conseguiu se utilizar do aparelho do Estado para difundir sua ideologia e construir uma nova hegemonia no país. Durante 14 anos no poder, Chávez possuía significativa legitimidade perante a população. Esta, explicada por suas políticas sociais, as chamadas “Missões Bolivarianas”. Neste sentido, nosso intuito consiste em analisar o governo Chávez a partir dos avanços sociais, buscando mostrar se houve o fortalecimento da democracia – no que se refere à educação, saúde e emprego, à diminuição da pobreza e a melhor distribuição de renda. Para tanto, tal análise se fará a partir da base de dados do Latinobarómetro, CEPAL e PNUD.ABSTRACTThe Chávez government (1999-2013) was in a process of ruptures with the political system in force until 1998, constituting a new block in power, in which President Chavez was able to use the state apparatus to spread his ideology and build a new hegemony in the country.

The application of occlusion in clinical practice part 1: Essential concepts in clinical occlusion
Authors: Mehta Shamir , Banerji Subir
Published: January 2019

Abstract: The first of this three-part series will focus on the occlusal assessment and the proposed features of the ‘ideal occlusal scheme’. The examination of the static and dynamic relationship of the dentition is outlined, including the extra- and intra-oral examination. The terminology associated with the intra-occlusal positions and relationships are described and a template for a comprehensive occlusal examination is presented. Part 1 also aims to explore some of the essential concepts in clinical occlusion.

CPD/Clinical Relevance: Understanding the static and dynamic relationships of the natural and restored dentition are important steps in the successful and long-term rehabilitation of missing and broken-down teeth. Development of familiarity and fluency with various terms associated with the examination and relationships of the dentition in function are critical aspects when attempting to form an appreciation of the subject of clinical occlusion.
Practical approaches to animal health issues on organic farms
Authors: Plate Peter
Published: January 2019

A summary of a workshop attended by 15 delegates at the BCVA congress on 19th October 2018. The workshop started with an overview of organic animal health standards and the organic market. In the EU animal health standards promote ‘positive health’ and preventive medicine, but treatments can be given without the animals losing their organic status. This is different in some other countries, especially the USA, and this is relevant when UK producers export produce. A misunderstanding of standards can lead to potential welfare problems, but correctly managed, organic standards promote high levels of welfare and health. Some examples of common health issues and their management within the organic system are given — mastitis, calf issues, Johne's control, trace element deficiencies and parasite control.
Ovine abortion — causes and diagnosis
Authors: Dun Kathryn
Published: January 2019

Annually it is estimated that 2–3% of the national flock will produce premature or stillborn lambs. However, infectious causes can also result in much higher abortion storms in individual flocks. An accurate diagnosis of infectious causes is important to manage the current abortion outbreak, safeguard farm workers from zoonotic infections and to allow control plans to be put into place for future years. This article will cover the diagnosis of ovine abortion and some of the main infectious causes in the UK flock.

Treating atrial fibrillation in the 21st Century: part 1
Authors: Redpath Adam , Bowen Mark
Published: January 2019

Atrial fibrillation (AF) is the most common pathological cardiac arrhythmia in the horse. While it may be an incidental finding in some horses, it can be an important cause of poor exercise tolerance in the performance horse, especially those working at extremes of cardiac function. Although quinidine sulfate remains the most widely used treatment option for horses, alternatives, such as transvenous electrocardioversion, are growing in popularity. The decision-making process to establish the most appropriate treatment is based on a number of factors including chronicity, underlying disease, and cardiac size. The availability of transvenous electrocardioversion in the horse provides a valid alternative for the treatment of horses with atrial fibrillation.
Morton’s interdigital neuroma: instructional review
Authors: Gougoulias Nikolaos , Lampridis Vasileios , Sakellariou Anthony
Published: January 2019

The terminology ‘Morton’s neuroma’ may represent a simplification of the clinical condition as the problem may not be a benign tumour of the nerve, but neuropathic foot pain associated with the interdigital nerve. Foot and ankle pathomechanics leading to metatarsalgia, clinical examination and differential diagnosis of the condition and imaging of the condition, for differential diagnosis, are discussed. Nonoperative management is recommended initially. Physiotherapy, injections (local anaesthetic, steroid, alcohol), cryotherapy, radiofrequency ablation and shockwave therapy are discussed. Operative treatment is indicated after nonoperative management has failed. Neuroma excision has been reported to have good to excellent results in 80% of patients, but gastrocnemius release and osteotomies should be considered so as to address concomitant problems. Key factors in the success of surgery are correct diagnosis with recognition of all elements of the problem and optimal surgical technique.

The role of alpha defensin in prosthetic joint infection (PJI) diagnosis: a literature review
Authors: Bonanzinga Tommaso , Ferrari Matteo Carlo , Tanzi Piergiuseppe , Vandenbulcke Filippo , Zahar Akos , Marcacci Maurilio
Published: January 2019

Prosthetic joint infection (PJI) management is not standardized worldwide and the outcome is frequently unsatisfactory. More and more arthroplasties are now being performed. An increasing number of highly virulent and antibiotic-resistant bacteria and an ageing population of patients presenting with many comorbidities make it necessary to focus on this important topic. Diagnosis of PJI remains challenging because the clinical signs and symptoms and elevation of systemic biomarkers (C-reactive protein, erythrocyte sedimentation rate) may be unclear. In the last few years, the clinical research has focused on synovial fluid biomarkers as a possible breakthrough in the complex scenario of PJI diagnosis. Synovial biomarkers have shown encouraging results and they should be used as diagnostic adjuncts to synovial white cell count and culture bacteriology. Synovial leukocyte esterase (LE) and synovial C-reactive protein (CRP) have been evaluated as good screening measures; however, the most promising synovial fluid biomarker in terms of sensitivity and specificity for PJI seems to be alpha defensin (AD). The laboratory-based alpha defensin enzyme-linked immunosorbent assay (ELISA) test demonstrated the highest ever reported accuracy for PJI diagnosis. However, an alpha defensin lateral flow test could have its place in ruling in a suspected PJI intraoperatively because of its high specificity and rapid results.

Politics and business in the history of a false teeth company, 1880s–1950s
Authors: De Vries David
Published: January 2019

The history of one firm dedicated to the development, manufacture and sale of false teeth might not immediately seem relevant to current topics and concerns within the study of fashion and beauty. ‘Good’ teeth have become important aesthetically and practically, in ‘real’ life and in media imagery. They pervade the catwalk, the media and the beauty industry. The ‘falseness’ of false teeth is not just a matter of utility but also of looking good, and has become part of the necessary toolkit of a person who knows how to take care of themselves, and look attractive. False teeth must look ‘real’ but also perfect (better than real), since they represent both the desire for physical perfection and for enhancement that is not detectible as false. Alongside prosthetics and cosmetic surgery, false teeth have come to be legitimate tools of bodily enhancement. The term ‘Hollywood smile’ partly refers to that ideal of flawless perfection.

This article is an analysis of ‘naturalization’ in several senses, involving migration of knowledge, technological advances, skills and capital between differing legislative, business and political environments – from Eastern Europe and the United States towards the end of the nineteenth century, and between Philadelphia and Palestine shortly after World War I. This historical investigation traces the aspirations, ideals and political motivations of a family, its founder and the firm they built up – the American Porcelain Tooth Company (APTC) – which became internationally renowned after its relocation from Philadelphia to Tel Aviv in Palestine, then under the British Mandate, after World War I.

The specific history and context of this company aims to shed new light on issues of globalization that are key to contemporary concerns in the fashion and beauty industries but are not captured by the study of technological inventions, marketing strategies or consumer preferences. The article interrogates the complex political negotiations and adaptations involved in such a migration. It proposes that beyond the specific historical context of the case examined here, attention paid to political aspects provides an essential methodological component and an added dimension to our understanding of the dynamics of the fashion and beauty market.

On Fire: Notes on the Spread of a Non-deterministic Schema
Authors: Lee Yaniya , Aiello Rosa
Published: January 2019

Yaniya Lee and Rosa Aiello’s contribution works with the material qualities of fire, with its historical significance, and, most significantly, with its respatizializing potential. In the path blazed by Sylvia Wynter and Katherine McKittrick’s demonic geographies, Lee and Aiello write fire as a challenge to Man’s ‘ “cartographic impulse”––the inclination to map, to rationalize, to appropriate, to own, and thereby to control space.’ Their piece experiments with the possibility of spread as literary form: ideas leap from one numbered-section to the next through words and logics, their scope engulfs myriad sources, their thought refuses to be contained.
Archiveology: Walter Benjamin and Archival Film Practices
Authors: Mitchell Aimée
Published: January 2019

This book review gives an overview of the key concepts and themes of Catherine Russell’s new book Archiveology: Walter Benjamin and Archival Film Practices. Russell describes ‘archiveology’ as a critical artistic practice of engaging with the archive: re-mixing, re-purposing, re-cutting, and re-contextualizing moving images. Her central interest lies in thinking about cinema as it passes into the digital in terms of translation and considers archiveology as a language through which we can understand media culture at this contemporary moment where analogue media takes on a new aura in its obsolescence.
Smoke Screens and Cinematic Representations of the MOVE Bombing
Authors: Hunter-Young Nataleah
Published: January 2019

Premiering in 2013, Jason Osder’s documentary film Let The Fire Burn chronicles the Philadelphia Police Department’s 1985 bombing of the Black revolutionary organization, MOVE. The bombing and subsequent fire – which the police commissioner let burn through 61 homes – resulted in the deaths of six adults and five children as well as the displacement of 250 people. Composed entirely of archival footage, Osder’s representation invokes a historicization and delimitation of an un-ended story about anti-Black state violence that, this essay argues, results in the obscuring of both MOVE’s continued struggle for freedom and the social conditions that make such actions possible. By thinking through collective memories of Black suffering and the ways in which they are mediated amidst a continued global assault on Black people, Hunter-Young explores what the temporal and spatial properties of smoke, and its relationship to fire, may signal about the sociocultural work of Osder’s film.
Seeing Skies Seemingly Blue
Authors: Rasmussen Elise
Published: January 2019

Through her work, research-based artist Elise Rasmussen explores epistemological aspects of ‘blueness’ as it relates to early photographic technologies (the cyanotype) and mountain exploration (the cyanometer, a device for measuring the blueness of the sky motivated the first expedition to the peak of Mount Blanc). As the colour blue ‘blue’ did not appear in written language until its pigment could be extracted by ‘man’ for ‘his’ use [sic]. Elise reflects on notions of (in)visibility, considering how, like smoke which blurs and blinds, blue plays with perception, and how both blue and smoke forces us to question the indexical capacity of photographic media to document reality.

A motiváció szerepe a felsőoktatási lemorzsolódásban és perzisztenciában
Authors: Kovács Eszter Karolina
Published: January 2019

A felsőoktatási oktatás lemorzsolódás jelentős oktatáspolitikai kérdés, amelynek hátterében számos befolyásoló faktor állhat. Az egyik legjelentősebb tényezőt a motiváció jelenti, s habár nehéz az öndeterminált és külső, mások által szabályozott motivációs szegmenseket élesen elkülöníteni egymástól, általánosságban nézve elmondható, hogy a belső motiváció a perzisztenciával korrelál, míg a külső motiváció inkább a lemorzsolódással hozható összefüggésbe. Tanulmányunkban e két típusú motiváció perzisztenciára gyakorolt hatását vizsgáltuk meg, az IESA-TESCEE 2015 (N=2015) adatbázisán keresztül. Eredményeink alapján a legkiemelkedőbb motivációs tényezőnek a baráti és családi példa követése mutatkozott, feltételezhetően internalizált motivációs bázisként. A tudásgyarapítás, valamint a munkavállalás kitolásának motivációja pozitívan hatott a perzisztenciára. Lineáris regresszióanalízisünk eredményei alapján a háttérváltozók kontrolálása mellett sem a külső, sem a belső motiváció faktorként való kezelése nem mutatott szignifikáns hatást a perzisztenciára, ugyanakkor a társadalmi háttérváltozók tekintetében a nem, az apa iskolai végzettsége, valamint a tanuló tagozatának típusa mutatkozott jelentősnek.
Hogyan dicsérjek?

Published: January 2019

A pozitív megerősítések hasznossága, személyiségépítő hatása a nevelés és az oktatás terén is egyre inkább a kutatások érdeklődési körébe kerül. Carol Dweck, az amerikai Stanford Egyetem kutatója számos tanulmányában kimondja: eddig tévúton jártunk, ha azt hittük, a dicséretnek kizárólag konstruktív hatása lehet. Nemcsak hátráltatnak és motiválatlanná tesznek a nem megfelelő szavak, hanem akár szorongást, görcsös megfelelési vágyat is kialakíthatnak, míg a jó dicséret erősíti a fejlődőképességünkbe vetett hitet és bátorít a nehezebb feladat elvégzésére. Vizsgálatunkban 69 ötödikes tanuló mintáján tanulmányoztuk a dicséret hatását a feladatválasztására és a beállítódásra, mely rámutat az erőfeszítésre irányuló dicséret pozitív hatásaira.

Authors: Ningrum Eva Liyan Woro , Widodo Aris Puji
Published: January 2019

GO-JEK is an information technology-based service consisting of 3 main services, namely GO-JEK, GO-LIFE, and GO-PAY. As time goes by, customer complaints arise about the lack of satisfaction with GO-JEK services. One measure of GO-JEK customer service satisfaction can be acknowledged by way of analyzing sentiments on the data of public opinion twett submitted on the twitter official account, @gojekindonesia. In this research, sentiment analysis was carried out using the Naïve Bayes Classifier learning algorithm. The number of data twitts used is 9987. The twit data is labeled according to the class which includes positive, negative and neutral classes. Then the next process is data preprocessing consisting of cleansing, tokenization, filtering, stemming, and stopword removal. The evaluation method using 10-fold cross validation with the results obtained is precision value of 80%, recall of 80%, f1-score of 80%, maximum accuracy of 82% and average accuracy of 79%.

Published: January 2019

We re-processed spectroscopic echelle data on 1999 S4 (LINIER), a catastrophically disintegrated comet, and 2001 Q4 (NEAT) obtained at not quite favorable circumstances. Photometric conditions at the observations were good but measurements of the spectra for the first one were performed at a large zenith distance and the second - with a relatively low spectral resolution. Nevertheless, we succeeded in detection and identification of fluorescent emission lines of 9 polycyclic aromatic hydrocarbons and simpler molecules in the spectra of both comets. Our results are in accordance with those of other authors and substantiate present notions about origin of the comets.
Derivations into annihilators of the ideals of Banach algebras
Authors: Teymouri Akram , Bodaghi Abasalt , Bagha Davood Ebrahimi
Published: January 2019

In this article, following Gorgi and Yazdanpanah, we define two new concepts of the ideal amenability for a Banach algebra A. We compare these notions with J-weak amenability and ideal amenability, where J is a closed two-sided ideal in A. We also study the hereditary properties of quotient ideal amenability for Banach algebras. Some examples show that the concepts of A/J-weak amenability and of J-weak amenability do not coincide for Banach algebras in general.
Design and Simulation of OFDM for BPSK, QPSK and QAM with Peak Power Reduction Using Clipping Technique
Authors: Kumar Arun
Published: January 2019

Due to the increase in demand for high data rates in mobile communication, orthogonal frequency division multiplexing (OFDM) system is employed in many applications. It efficiently overcomes the effect of Inter-symbol Interference caused due to the fading of the channel, but Peak to Average Power Ratio (PAPR) is unitary of the disadvantages in OFDM System. In the stage-I, the OFDM system is designed with different modulation schemes like QAM-16, BPSK, and QPSK. In the latter stage, we work on the reduction of PAPR by using a clipping technique and we establish a significant reduction in PAPR as compared to the conventional clipping technique.
Sea level accelerations at globally distributed tide gauge stations during the satellite altimetry era
Authors: Iz H. Bâki , Shum C. K. , Kuo C. Y.
Published: January 2019

This observational study reports that several globally distributed tide gauge stations exhibit a propensity of statistically significant sea level accelerations during the satellite altimetry era. However, the magnitudes of the estimated tide gauge accelerations during this period are systematically and noticeably smaller than the global mean sea level acceleration reported by recent analyses of satellite altimetry. The differences are likely to be caused by the interannual, decadal and interdecadal sea level variations, which are modeled using a broken trend model with overlapping harmonics in the analyses of tide gauge data but omitted in the analysis of satellite altimetry.

Measures on effect algebras

Published: January 2019

We study measures defined on effect algebras. We characterize real-valued measures on effect algebras and find a class of effect algebras, that include the natural effect algebras of sets, on whichσ-additive measures with values in a finite dimensional Banach space are always bounded. We also prove that in effect algebras the Nikodym and the Grothendieck properties together imply the Vitali-Hahn-Saks property, and find an example of an effect algebra verifying the Vitali-Hahn-Saks property but failing to have the Nikodym property. Finally, we define the concept of variation for vector measures on effect algebras proving that in effect algebras verifying the Riesz Decomposition Property, the variation of a finitely additive vector measure is a finitely additive positive measure.

Published: January 2019

The notion of porouscontinuity was introduced by Borsík and Holos. We find classes of functions whose compositions with porouscontinuous functions are still porouscontinuous. Next, we study compositions of porouscontinuous functions with homeomorphisms. We investigate connections between 𝓘𝓒(𝓐) ∩ 𝓗𝓞𝓜 and 𝓘𝓒(𝓑) ∩ 𝓗𝓞𝓜 for different classes 𝓐,𝓑 ∈ 𝓟𝓒, where 𝓟𝓒 is the set of all classes of porouscontinuous functions and 𝓗𝓞𝓜 is the set of all homeomorphisms f : ℝ → ℝ.
When Public Art Goes Bad: Two Competing Features of Public Art
Authors: Willard Mary Beth
Published: January 2019

Not all public art is bad art, but when public art is bad, it tends to be bad in an identifiable way. In this paper, I develop a Waltonian theory of the category of public art, according to which public art standardly is both accessible to the public and minimally site-specific. When a work lacks the standard features of the category to which it belongs, appreciators tend to perceive the work as aesthetically flawed. I then compare and contrast cases of successful and unsuccessful public art to show that accessibility and site-specificity are features which tend to preclude the other. It is difficult, although hardly impossible, for a site-specific work to remain accessible, and difficult for an accessible work to engage adequately with the site on which it is situated. As a result, while not all public art is bad, the features peculiar to public work encourage a latent tendency toward badness.

Published: January 2019

The most important plastic resins used in wire coating are high/low density polyethylene (LDPE/HDPE), plasticized polyvinyl chloride (PVC), nylon and polysulfone. To provide insulation and mechanical strength, coating is necessary for wires. Simulation of polymer flow during wire coating dragged froma bath of Oldroyd 8-constant fluid incompresible and laminar fluid inside pressure type die is carried out numerically. In wire coating the flow depends on the velocity of the wire, geometry of the die and viscosity of the fluid.The non-dimensional resulting flow and heat transfer differential equations are solved numerically by Ruge-Kutta 4th-order method with shooting technique. Reynolds model and Vogel’s models are encountered for temperature dependent viscosity. The numerical solutions are obtained for velocity field and temperature distribution. The solutions are computed for different physical parameters.It is observed that the non-Newtonian propertis of fluid were favourable, enhancing the velocity in combination with temperature dependent variable. The Brinkman number contributes to increase the temperature for both Reynolds and Vogel’smodels. With the increasing of pressure gradient parameter of both Reynolds and Vogel’s models, the velocity and temperature profile increases significantly in the presence of non-Newtonian parameter. Furthermore, the present result is also compared with published results as a particular case.
Face recognition method based on GA-BP neural network algorithm
Authors: Liu Jing , Ashraf Muhammad Aqeel
Published: January 2019

In order to recognize faces, face recognition methods need to be studied. When a face is identified by the current method, the image denoising effect is poor, the face image recognition result thus has error, the time used to recognize the face image is long, the signal to noise ratio, the recognition result and the recognition efficiency are low. Based on the GA-BP neural network algorithm, a face recognition method is proposed. A mixed denoising model of face images is constructed by combining dictionary based sparse representation with non-local similarity. The principal component analysis method is used to extract the feature of the face image after denoising and staining the eigenvector of the face image. The GA-BP neural network algorithm is used to optimize the initial weights and thresholds so as to achieve the optimal value. The feature vectors of face images are ted into the genetic neural network to complete face recognition. Experimental results show that the proposed method has high signal-to-noise ratio, accuracy and recognition efficiency.
Optimal path selection algorithm for mobile beacons in sensor network under non-dense distribution
Authors: Yu Guoqing , Ma Hongtao , Witarsyah Deden
Published: January 2019

When the traditional anchor aided location algorithm is used to select the mobile beacon path in the sensor network, there is no analysis of the energy imbalance of nodes in non-dense conditions, the optimal network node cannot be selected, and the selection error of the optimal path of the beacon is larger. A path selection algorithm for mobile beacons in a sensor network under non-dense distribution is proposed. Using the mobile beacon based wireless sensor network location algorithm, the weighted centroid algorithm and the extended Kalman filter (EKF) are used to obtain the accurate location results of the unknown nodes around the mobile beacon in the sensor network under non-dense distribution condition. The optimal node energy partition of the unknown node is obtained by the chaotic differential evolution method, and the optimal location of the optimal energy node in the wireless sensor network is calculated using the dynamic escape particle swarm optimization method, and the optimal beacon path is extracted. The experimental results show that the proposed algorithm can enhance the clustering performance of the optimal node in the wireless sensor network and has a better performance of dynamic node selection in wireless sensor network, and the convergence speed is faster and the operation time is shorter.
