Published: February 2021

The rainfall-runoff model is commonly used in flood discharge computation. One of the most frequently employed methods to estimate the flood discharge in the ungauged basin is NRCS-CN. This study is aimed to determine the CN value with/without soil drainage capacity from the soil information in SPT Indonesia. The location used is Pataruman watershed by calibrating the simulation discharge results with the observed discharge. Soil conditions in the Pataruman watershed show that the soil texture has a fine texture (HSG D), a slightly fine texture (HSG C), and a slightly coarse texture (HSG A). The average composite CN in the Pataruman watershed without soil drainage capacity was 85.58 while soil drainage capacity was 81.01. The results of the analysis show that with/without taking into account the soil drainage capacity in the Pataruman watershed there is no significant difference in discharge with a relation coefficient of 0.734 (without soil drainage capacity) and 0.732 (with soil drainage capacity). CN calculations with/without soil drainage capacity are recommended for small watersheds.
National influenza mid-season report, 2020–2021
Authors: Lee Lisa , Butt Kelly , Buckrell Steven , Nwosu Andrea , Sevenhuysen Claire , Bancej Christina
Published: February 2021

Canada's national influenza season typically starts in the latter half of November (week 47) and is defined as the week when at least 5% of influenza tests are positive and a minimum of 15 positive tests are observed. As of December 12, 2020 (week 50), the 2020-2021 influenza season had not begun. Only 47 laboratory-confirmed influenza detections were reported from August 23 to December 12, 2020; an unprecedentedly low number, despite higher than usual levels of influenza testing. Of this small number of detections, 64% were influenza A and 36% were influenza B. Influenza activity in Canada was at historically low levels compared with the previous five seasons. Provinces and territories reported no influenza-associated adult hospitalizations. Fewer than five hospitalizations were reported by the paediatric sentinel hospitalization network. With little influenza circulating, the National Microbiology Laboratory had not yet received samples of influenza viruses collected during the 2020-2021 season for strain characterization or antiviral resistance testing. The assessment of influenza vaccine effectiveness, typically available in mid-March, is expected to be similarly limited if low seasonal influenza circulation persists. Nevertheless, Canada's influenza surveillance system remains robust and has pivoted its syndromic, virologic and severe outcomes system components to support coronavirus disease 2019 (COVID-19) surveillance. Despite the COVID-19 pandemic, the threat of influenza epidemics and pandemics persists. It is imperative 1) to maintain surveillance of influenza, 2) to remain alert to unusual or unexpected events and 3) to be prepared to mitigate influenza epidemics when they resurge.

Authors: Boyd Eva , Trmcic Aljosa , Taylor Marsha , Shyng Sion , Hasselback Paul , Man Stephanie , Tchao Christine , Stone Jason , Janz Loretta , Hoang Linda , Galanis Eleni
Published: February 2021

Background: In 2018, a Shiga toxin–producing Escherichia coli O121 outbreak that affected seven individuals was associated with raw milk Gouda-like cheese produced in British Columbia, Canada. Objectives: To describe the E. coli O121 outbreak investigation and recommend greater control measures for raw milk Gouda-like cheese. Methods: Cases of E. coli O121 were identified through laboratory testing results and epidemiologic surveillance data. The cases were interviewed on exposures of interest, which were analyzed against Foodbook Report values for British Columbia. Environmental inspection of the dairy plant and the cheese products was conducted to ascertain a source of contamination. Whole genome multi-locus sequence typing (wgMLST) was performed on all positive E. coli O121 clinical and food isolates at the provincial laboratory. Results: Four out of the seven cases consumed the same raw milk Gouda-like cheese between August and October 2018. The implicated cheese was aged longer than the required minimum of 60 days, and no production deficiencies were noted. One sample of the implicated cheese tested positive for E. coli O121. The seven clinical isolates and one cheese isolate matched by wgMLST within 6.5 alleles. Conclusion: Raw milk Gouda and Gouda-like cheese has been implicated in three previous Shiga toxin–producing E. coli outbreaks in North America. It was recommended product labelling to increase consumer awareness and thermization of milk to decrease the risk of illness associated with raw milk Gouda and Gouda-like cheese.
The use of an online survey for collecting food exposure information, Foodbook sub-study, February to April 2015
Authors: Gardhouse Christine , Hurst Matt , Sivanantharajah Sujani , Ciampa Nadia
Published: February 2021

Background: During foodborne illness outbreak investigations, comparing food exposure frequencies of cases to those of a control population can help identify suspect food sources. The Public Health Agency of Canada (PHAC) conducted an online survey between February and April 2015 to collect seven-day food exposures from a convenience sample. The study period overlapped with a national, population-based exposure survey being conducted via telephone using random digit dialling. A subset of the food exposure questions from the telephone-based survey was included in the online survey. Objective: The online survey study objectives were to: 1) describe the survey methodology, survey respondents and response behaviour; and 2) determine if the online methodology is an appropriate alternative to telephone surveys by comparing food exposures. Methods: The online survey link was distributed via email to employees and public health partners, and was promoted on the PHAC website and social media channels. Results: In total 2,100 surveys were completed. The majority of respondents were female, with high income and education, aged 30 to 39 years. The proportion reporting consuming the food items in the online survey was generally higher than those reported in the telephone survey, with a mean difference of 6.0% (95% CI: 4.2, 7.8). Conclusion: In an outbreak investigation, the 6.0% bias could make it more difficult to detect a difference between the case and control food exposures. Nevertheless, given the speed of response and lower resource expenditure of online surveys as well as the willing, able and convenient sample, a bias of 6.0% is considered small enough to be acceptable for future surveys.
Utilisation d’un sondage en ligne pour la collecte de renseignements sur l’exposition aux aliments, sous-étude Foodbook, de février à avril 2015
Authors: Gardhouse Christine , Hurst Matt , Sivanantharajah Sujani , Ciampa Nadia
Published: February 2021

Contexte : Lors des enquêtes sur les éclosions de maladies d’origine alimentaire, la comparaison des fréquences des expositions aux aliments des cas avec celles d’une population témoin peut aider à déterminer les sources alimentaires suspectes. L’Agence de la santé publique du Canada (l’Agence) a mené un sondage en ligne entre février et avril 2015 afin de recueillir des données sur l’exposition aux aliments pendant sept jours à partir d’un échantillon de commodité. La période de l’étude a coïncidé avec un sondage téléphonique au hasard à l’échelle nationale sur l’exposition de la population. Un sous-ensemble de questions sur l’exposition aux aliments provenant du sondage téléphonique a été inclus au sondage en ligne. Objectif : Les objectifs du sondage en ligne étaient les suivants : 1) décrire la méthodologie du sondage, les répondants et le comportement de réponse; et 2) déterminer si la méthodologie en ligne est une solution de rechange aux sondages téléphoniques en comparant les expositions aux aliments. Méthodes : Le lien vers le sondage en ligne a été distribué par courrier électronique aux partenaires et aux employés de la santé publique, et a fait l’objet de promotion sur le site Web de l’Agence et dans les médias sociaux. Résultats : Au total, 2 100 sondages ont été réalisés. La majorité des répondants étaient des femmes, âgées de 30 à 39 ans, ayant un revenu et un niveau d’éducation élevés. La proportion de personnes ayant déclaré avoir consommé des produits alimentaires dans le cadre du sondage en ligne était généralement plus élevée que dans le sondage téléphonique, avec une différence moyenne de 6,0 % (IC à 95 % : 4,2, 7,8). Conclusion : Dans une enquête sur une éclosion, le biais de 6,0 % pourrait rendre plus difficile la détection d’une différence entre le cas et le témoin des expositions aux aliments. Néanmoins, compte tenu de la rapidité des réponses et des dépenses plus faibles des sondages en ligne ainsi que de l’échantillon volontaire, compétent et commode, un biais de 6,0 % est considéré comme suffisamment faible pour être acceptable pour les sondages futurs.
HIV in Canada—surveillance report, 2019
Authors: Haddad Nisrine , Weeks Ashley , Robert Anita , Totten Stephanie
Published: February 2021

Background: Human immunodeficiency virus (HIV) is a global public health issue. HIV has been nationally notifiable in Canada since 1985. The Public Health Agency of Canada (PHAC) monitors trends in new HIV diagnoses. Objectives: The objective of this surveillance report is to provide an overview of the epidemiology of reported HIV cases in 2019 in Canada. The report highlights 10-year trends (2010–2019). Data on HIV diagnosed through Immigration Medical Exams (IME) and trends in perinatal transmission of HIV are also presented. Methods: PHAC monitors HIV through the HIV/AIDS Surveillance System, a passive, case-based system that collates non-nominal data submitted voluntarily by all Canadian provinces and territories. Descriptive analyses were conducted on national data. IME data were obtained from Immigration, Refugees and Citizenship Canada (IRCC), and data on HIV-exposed pregnancies were obtained through the Canadian Perinatal HIV Surveillance Program. Results: In 2019, a total of 2,122 HIV diagnoses were reported in Canada (5.6 per 100,000 population). Saskatchewan reported the highest provincial diagnosis rate at 16.9 per 100,000 population. The 30 to 39-year age group had the highest HIV diagnosis rate at 12.7 per 100,000 population. While the rates for both males and females fluctuated in the past decade, since 2010 the rates among males decreased overall, while the rate among females increased slightly. As in previous years, the diagnosis rate for males in 2019 was higher than that for females (7.9 versus 3.4 per 100,000 population, respectively). The highest proportion of all reported adult cases with known exposure were gay, bisexual and other men who have sex with men (gbMSM, 39.7%), followed by cases attributed to heterosexual contact (28.3%) and among people who inject drugs (PWID, 21.5%). The number of migrants who tested positive for HIV during an IME conducted in Canada was 626. The one documented perinatal HIV transmission related to a mother who had not received antepartum or intrapartum antiretroviral therapy prophylaxis. Conclusion: The number and rate of reported HIV cases in Canada has remained relatively stable over the last decade, with minor year-to-year variations. As in previous years, the gbMSM and PWID populations represent a high proportion of HIV diagnoses, although a sizable number of cases were attributed to heterosexual contact. It is important to routinely monitor trends in HIV in light of pan-Canadian commitments to reduce the health impact of sexually transmitted and blood-borne infections by 2030.

Beyond the Coronavirus: Understanding Crises of Social Reproduction
Authors: Rao Smriti
Published: February 2021

From a feminist political economy perspective, the unfolding of the coronavirus is a further reminder of the fundamental contradiction between a capitalist system that prioritises profits, and a feminist ethic that prioritises life-making or social reproduction. This article argues for a more systematic understanding of crises of social reproduction under capitalism, stressing the difference between such crises for labour and those for capital. The coronavirus crisis represents an extraordinary example of a crisis of social reproduction for capital, but this article examines crises of social reproduction for capital and labour that arise from the more ordinary workings of capitalism. The focus is on unfolding such crises in the Global South, using the case of India to illustrate the usefulness of such an analysis.

Las primeras imágenes del indio americano: problemas para su construcción
Authors: Pastor Marialba
Published: February 2021

Este texto plantea cómo, entre 1520 y 1555, la imagen del indio americano fue moldeada por autores españoles en escritos, crónicas civiles y de evangelización, para transformarlo de bárbaro en cristiano en potencia. El trabajo argumenta que tal transformación respondió tanto a los conflictos de la monarquía católica con las potencias europeas y del medio oriente, como a la importancia que los “indios” representaron para el destino de Roma y España. Subraya el peso de los intereses en la conformación de dicha imagen, a fin de advertir la tergiversación de la realidad histórica y cultural de las comunidades americanas que ello significó. Además, muestra lo absurdo que resulta tomar las fuentes de esta época de primera mano textual o acríticamente.

El objetivo es proponer la revisión de la documentación elaborada por la administración central lasallista en Roma, entre 1966 y 1989, como una vía para la comprensión y la escritura del pasado posconciliar lasallista, un caso que, a su vez, proporciona luz sobre la situación de las órdenes religiosas educadoras en el siglo XX. Así pues, para el cumplimiento de este propósito, se examinará un corpus documental compuesto por las Cartas del Hermano Superior General, los Capítulos Generales, las Circulares y algunos órganos de difusión elaborados en la Casa Generalicia de este instituto religioso.
Coordinated Prefrontal State Transition Leads Extinction of Reward-Seeking Behaviors
Authors: Russo Eleonora , Ma Tianyang , Spanagel Rainer , Durstewitz Daniel , Toutounji Hazem , Köhr Georg
Published: February 2021

Extinction learning suppresses conditioned reward responses and is thus fundamental to adapt to changing environmental demands and to control excessive reward seeking. The medial prefrontal cortex (mPFC) monitors and controls conditioned reward responses. Abrupt transitions in mPFC activity anticipate changes in conditioned responses to altered contingencies. It remains, however, unknown whether such transitions are driven by the extinction of old behavioral strategies or by the acquisition of new competing ones. Usingin vivomultiple single-unit recordings of mPFC in male rats, we studied the relationship between single-unit and population dynamics during extinction learning, using alcohol as a positive reinforcer in an operant conditioning paradigm. To examine the fine temporal relation between neural activity and behavior, we developed a novel behavioral model that allowed us to identify the number, onset, and duration of extinction-learning episodes in the behavior of each animal. We found that single-unit responses to conditioned stimuli changed even under stable experimental conditions and behavior. However, when behavioral responses to task contingencies had to be updated, unit-specific modulations became coordinated across the whole population, pushing the network into a new stable attractor state. Thus, extinction learning is not associated with suppressed mPFC responses to conditioned stimuli, but is anticipated by single-unit coordination into population-wide transitions of the internal state of the animal.

SIGNIFICANCE STATEMENTThe ability to suppress conditioned behaviors when no longer beneficial is fundamental for the survival of any organism. While pharmacological and optogenetic interventions have shown a critical involvement of the mPFC in the suppression of conditioned responses, the neural dynamics underlying such a process are still largely unknown. Combining novel analysis tools to describe behavior, single-neuron response, and population activity, we found that widespread changes in neuronal firing temporally coordinate across the whole mPFC population in anticipation of behavioral extinction. This coordination leads to a global transition in the internal state of the network, driving extinction of conditioned behavior.
Синтаксемный анализ в сравнительном языкознании (на материале русского и польского языков)
Authors:   Uniwersytet Śląski w Katowicach, Borek Małgorzata
Published: February 2021

The author of the article grounds her studies on the linguistic theory of syntactemes by Galina Zolotova. Any syntax construction may be studied in an analysis plan, as well as synthesis defined as syntacteme combination. The defined morphological form of expression may consist of various syntactemes. The aim of the article is to confrontatively analyse name syntactemes characteristic for the Russian language chosen from Sintaksicheskij slovar by Galina Zolotova and their equivalents in Polish. According to the author, the systematic analysis of syntactemes in the confrontative approach gives the possibility for the preparation of a scheme of elementary syntactic units of Russian and Polish, which may be used for glottodidactic aims, as well as in linguistic text studies.
Социокультурная адаптация и обучение украинских студентов-мигрантов в Словакии
Authors:   Prešovská univerzita v Prešove, Petríková Anna
Published: February 2021

The aim of the research is to identify the main problems and needs in the teaching of Ukrainian migrant students who study at the Faculty of Philosophy in the field of Russian Philology (options: Translation Studies, Teaching speciality, Russian Studies) in Preshov, Slovakia. In the article socio-pedagogical and linguistic research methods (social adaptation of migrants, behavioural stereotypes, observation, analysis, interpretation, survey) are used. The obtained results relate to the current situation of academic migration in Slovakia, the problem of ethnocultural adaptation of migrant students to the local environment (the problem of personal disorder, ignorance of the cultural realities of the Slovak population), problems in learning due to lack of knowledge of the Slovak language, and lack of knowledge of literary Russian language, which is subject to strong interference at almost all language levels. Teachers are faced with the task of educating in an academic culture, and with knowledge of the Slovak mentality. Undoubtedly, migrant students are most susceptible to the emotional experience of social instability, but the psychological crisis passes rather quickly and should not affect the long-term negative indicators of students’ academic success.
Discrete units as markers of English/Polish contrasts in company registration discourse
Authors:   Uniwersytet Rzeszowski, Więcławska Edyta
Published: February 2021

The paper addresses the issue of the complexity of legal communication in an interlingual perspective. The analysis fits in the paradigmatic approach to contrastive studies, where the distribution of discrete units is presented in quantitative terms. The cross-linguistic, computational account of the distribution of selected discrete units across company registration documentation shows systemic distinctions. It discloses recurrent, symmetrical and asymmetrical patterns which result from language system-inherent distinctions and/or the operation of translation universals. The strong point of the research lies in addressing legal communication within the realm of secondary genres, which – for practical reasons – are underrepresented in jurilinguistic studies. The study is based on a custom -designed, parallel corpus comprised of authentic materials.
Inhibition of MTOR signaling impairs rat embryo organogenesis by affecting folate availability
Authors: Higa Romina , Rosario Fredrick J , Powell Theresa L , Jansson Thomas , Jawerbaum Alicia
Published: February 2021

Mechanistic target of rapamycin (MTOR) is essential for embryo development by acting as a nutrient sensor to regulate cell growth, proliferation and metabolism. Folate is required for normal embryonic development and it was recently reported that MTOR functions as a folate sensor. In this work, we tested the hypothesis that MTOR functions as a folate sensor in the embryo and its inhibition result in embryonic developmental delay affecting neural tube closure and that these effects can be rescued by folate supplementation. Administration of rapamycin (0.5 mg/kg) to rats during early organogenesis inhibited embryonic ribosomal protein S6, a downstream target of MTOR Complex1, markedly reduced embryonic folate incorporation (−84%, P < 0.01) and induced embryo developmental impairments, as shown by an increased resorption rate, reduced embryo somite number and delayed neural tube closure. These alterations were prevented by folic acid administered to the dams. Differently, although an increased rate of embryonic rotation defects was observed in the rapamycin-treated dams, this alteration was not prevented by maternal folic acid supplementation. In conclusion, MTOR inhibition during organogenesis in the rat resulted in decreased folate levels in the embryo, increased embryo resorption rate and impaired embryo development. These data suggest that MTOR signaling influences embryo folate availability, possibly by regulating the transfer of folate across the maternal–embryonic interface.
Comparison of Foveated Downsampling Techniques in Image Recognition
Authors: Torabian Parsa , Pradeep Ronak , Orchard Jeff , Tripp Bryan
Published: February 2021

Foveation is an important part of human vision, and a number of deep networks have also used foveation. However, there have been few systematic comparisons between foveating and non-foveating deep networks, and between different variable-resolution downsampling methods. Here we define several such methods, and compare their performance on ImageNet recognition with a custom Densenet network. The best variable-resolution method slightly outperforms uniform downsampling. Thus in our experiments, foveation does not substantially help or hinder object recognition in deep networks.
Locally Adaptive Thresholding for Single-Shot Structured Light Patterns
Authors: Sadatsharifi Kasra , Naiel Mohamed A. , Lamm Mark , Fieguth Paul
Published: February 2021

Image thresholding is a challenging task due to its sensitivity to environmental variations and degradation in the quality of the captured image. Although many image thresholding methods have been introduced, most of them require the fine tuning of a thresholding parameter that is not suitable for single-shot structured light (SSSL) based projector-camera applications. In this paper, we introduce a locally adaptive thresholding method with automatic parameter selection based on the local statistics of the distinct image partitions. For assessing the proposed scheme, we introduce an evaluation that relies on mapping SSSL patterns between the camera and projector spaces. Experimental results demonstrate the effectiveness of the proposed technique by maintaining the thresholding accuracy of the baseline method, without the need to fine tune the obtained thresholding parameter or any noticeable change in the qualitative results.
Communication Strategies Used in Teaching Media Information Literacy for Combating Hoaxes in Indonesia: A Case Study of Indonesian National Movements
Authors: Ummah Nurul Hidayatul , Fajri Muchamad Sholakhuddin Al
Published: February 2021

This study examined communication strategies used by Indonesian national movements to teach media information literacy as an endeavour to fight hoaxes. The in-depth online interview and content analysis had been employed to investigate approaches of the movement to campaign media information literacy competence to society. The findings reveal that the offline communication has been massively applied by the movement to establish direct engagement to give a comprehensive understanding. Moreover, in the case of online communication, the content of Instagram shows that the movements predominantly use Instagram for marketing tools which post much information related to offline activities, instead of educated contents that contain media information literacy understanding. This study suggests that educating media information literacy through online communication should be prioritised, as 140 million Indonesians are active social media users, dominated by the youth aged 18-24 who are prone to be attacked by fake news.
Problematic shopping and self-injurious behaviors in adolescents
Authors: Greenberg Norman R. , Zhai Zu Wei , Hoff Rani A. , Krishnan-Sarin Suchitra , Potenza Marc N.
Published: February 2021

Background and aims

Self-injurious behaviors (SIBs) and problematic shopping (PS) are both prevalent in adolescents. These behaviors have been proposed as behavioral addictions and linked to impulsivity (Imp) and sensation-seeking (SS). They are also associated with negative mental health and psychosocial measures. This study examined relationships between PS and SIB in adolescents. It also examined how PS and SIB relate to Imp and SS, and interactions between PS and SIB in relation to health/functioning measures.

Methods

Survey data from 2,624 Connecticut high-school students were evaluated using chi-square analyses. Next, logistic regression models were used to assess relationships between PS and measures of SIB. T-tests compared Imp and SS in adolescents with and without PS and SIB. Interaction analyses assessed effects of PS on relationships between SIB and health/functioning measures.

Results

Adolescents with PS had 3.43-fold higher odds of endorsing lifetime SIB than those without PS, and were more likely to exhibit severe SIB and disruption due to SIB. PS and SIB were associated with elevated Imp and SS. Interaction analyses revealed that in adolescents with PS, the relationships between SIB and substance use was weaker than in adolescents without PS. This suggests PS accounts for variance in relationships between SIB and substance use.

Discussion and conclusions

PS is strongly related to SIB prevalence, severity, and impairment in adolescents, and weakens associations between SIB and substance use. PS should therefore be considered for prevention efforts for SIB. Further research should investigate mechanisms connecting PS and SIB and explore possible interventions targeting associated features like Imp and SS.
Prerequisites for stakeholder framework: Consumer advocacy and health protection in the digital industry. •
Authors: Lee Hae Kook
Published: February 2021

The World Health Organization (WHO) included gaming disorders in International Classification of Disease-11th (ICD-11) on May 25, 2019. Since then, some academics and the gaming industry have continued to argue over the health system's response to online addictive behaviors. Under these circumstances, a framework involving groups representing various interests is needed to derive a reasonable solution to the dispute over the inclusion of gaming disorders in ICD-11. For this framework to work effectively, it is necessary to agree on consistent and advanced research findings that harms related to the excessive use of digital devices or content continue to occur empirically all over the world and that addictive use constitutes a primary addictive disorder. The problematic risk taking involving emerging technologies may include not only health risks from addictive use, but also more general harms associated with digital ethics and norms such as privacy and transparent money transactions. An understanding of a public health model of addiction is required to reduce harms associated with online addictive behavior that exist behind risk taking. Such harms are also mediated by excessive use, excessive money spending, and exposure to addictive content such as violence and pornography. Major stakeholders and their roles can be derived more effectively based on these conceptual models and parameters of harms. In conclusion, the context of the proposed stakeholder framework should be further optimized on the basis of two principles: (1) advocating consumer rights as a general and standard approach to digital products; and (2) protecting consumers' health from harms related to addictive behaviors.
Mediating effects of rumination and bedtime procrastination on the relationship between Internet addiction and poor sleep quality
Authors: You Zhiqi , Mei Weijie , Ye Na , Zhang Lu , Andrasik Frank
Published: February 2021

Background and aims

Numerous studies have shown that people who have Internet addiction (IA) are more likely to experience poor sleep quality than people who do not. However, few studies have explored mechanisms underlying the relation between IA and poor sleep quality. As a first attempt to address this knowledge gap, a cross-sectional design was applied, and structural equation modeling was used to explore the direct relationship between IA and poor sleep quality, as well as the potential mediating roles of rumination and bedtime procrastination.

Methods

A convenience sample, consisting of 1,104 Chinese University students (696 females or 63%), completed an online survey that included the following measures: Young’s 8-item Internet Addiction Diagnosis Questionnaire, the Pittsburgh Sleep Quality Index, the Ruminative Responses Scale, and the Bedtime Procrastination Scale.

Results

While the direct path between IA and poor sleep quality was not found to be significant, rumination and bedtime procrastination were each shown to separately mediate the predictive effect of IA on poor sleep quality. However, the greatest level of support was found for the sequential mediating effects of rumination and bedtime procrastination between IA and poor sleep quality.

Conclusion

While rumination and bedtime procrastination were both shown to be important independent mediators for the relation between IA and poor sleep quality, their combined effect was as great as either alone.
Sensitivity estimation for calculated phase equilibria
Authors: Otis Richard , Bocklund Brandon , Liu Zi‐Kui
Published: February 2021

The development of a consistent framework for Calphad model sensitivity is necessary for the rational reduction of uncertainty via new models and experiments. In the present work, a sensitivity theory for Calphad was developed, and a closed‐form expression for the log‐likelihood gradient and Hessian of a multi‐phase equilibrium measurement was presented. The inherent locality of the defined sensitivity metric was mitigated through the use of Monte Carlo averaging. A case study of the Cr–Ni system was used to demonstrate visualizations and analyses enabled by the developed theory. Criteria based on the classical Cramér–Rao bound were shown to be a useful diagnostic in assessing the accuracy of parameter covariance estimates from Markov Chain Monte Carlo. The developed sensitivity framework was applied to estimate the statistical value of phase equilibria measurements in comparison with thermochemical measurements, with implications for Calphad model uncertainty reduction.
Recent developments on fabrication of Al‐matrix composites reinforced with quasicrystals: From metastable to conventional processing
Authors: Wolf Witor , Bolfarini Claudemiro , Kiminami Claudio S. , Botta Walter J.
Published: February 2021

Quasicrystalline alloys and their composites have been extensively studied due to their complex atomic structures, mechanical properties, and their unique tribological and thermal behaviors. However, technological applications of these materials have not yet come of age and still require additional developments. In this review, we discuss the recent advances that have been made in the last years toward optimizing fabrication processes and properties of Al‐matrix composites reinforced with quasicrystals. We discuss in detail the high‐strength rapid‐solidified nanoquasicrystalline composites, the challenges involved in their manufacturing processes and their properties. We also bring the latest findings on the fabrication of Al‐matrix composites reinforced with quasicrystals by powder metallurgy and by conventional metallurgical processes. We show that substantial developments were made over the last decade and discuss possible future studies that may result from these recent findings.

Transition metal dichalcogenides have shown great potential for next-generation electronic and optoelectronic devices. However, native oxidation remains a major issue in achieving their long-term stability, especially for Zr-containing materials such as ZrS2. Here, we develop a first principles-informed reactive forcefield for Zr/O/S to study oxidation dynamics of ZrS2. Simulation results reveal anisotropic oxidation rates between (210) and (001) surfaces. The oxidation rate is highly dependent on the initial adsorption of oxygen molecules on the surface. Simulation results also provide reaction mechanism for native oxide formation with atomistic details.

Authors: Yulandri Elsa , Hartati Neneng
Published: February 2021

AbstractIn investment transactions in the capital market, an investor will expect a higher level of investment invested. In order for the expected results to be appropriate, it is necessary to analyze the financial statements of a company with fundamental and technical analysis. This article aims to show the effect of inflation and ROI with the du pont system method on the stock return of PT. Lippo Karawaci, Tbk. Inflation is an increase in the price of goods and services in general over a long period of time. Meanwhile, the ROI du pont system is a ratio that measures how good the total assets can generate investment. This article also uses descriptive methods and quantitative approaches, namely to describe the research results presented in numerical form. The data in this article is secondary data taken from the financial statements of PT. Lippo Karawaci, Tbk, and supported by a library and documentation studio, which is processed statistically and quantitatively. The results of the study concluded that both partially and simultaneously inflation and ROI with the Du Pont System method did not have a significant effect on stock returns of PT. Lippo Karawaci. The second variable contribution is only 31%, meaning that it is 69% stock return, other factors are outside this study. Keywords: Inflation, ROI with the Du Pont System Method, Stock Return. AbstrakDalam transaksi investasi di pasar modal, seorang investor akan mengharapkan tingkat pengembalian yang tinggi atas investasi yang ditanamkan.

Bagi perekonomian suatu Negara, pasar modal memiliki peran yang sangat penting karena pasar modal menjalankan dua fungsi, yaitu pertama pasar modal sebagai sarana bagi pendanaan usaha atau sebagai sarana untuk mendapatkan dana dari masyarakat pemodal (investor). Kedua, yaitu pasar modal sebagai sarana bagi masyarakat untuk berinvestasi pada instrumen keuangan. Keikutsertaan masyarakat investor melalui instrumen pasar modal menjadi harapan bersama untuk memberikan sumbangan bagi pembangunan ekonomi secara nasional (idx.co.id). Jumlah investor di pasar modal memang terus meningkat, namun jumlah tersebut masih sangat sedikit bahkan tidak mencapai 1% dari total penduduk indonesia. hal ini menunjukkan bahwa perekonomian indonesia masih memiliki sangat banyak peluang untuk berkembang melalui pasar modal namun masih belum dimanfaatkan secara maksimal.

The subject of this paper are the new discoveries of antler cheekpieces of horse harness at Trzciniec Culture sites in Morawianki, Miechow and Jakuszowice (Little Poland, Poland). It also addresses the issue of double horse burials being parts of sepulchral complexes, with barrows at their centres. The article tackles the problem of the occurrence of such burials and cheekpieces in the Danubian regions, the steppe zone of Eastern Europe and in the territory of Greece. It also considers the function of cheekpieces, as parts of horse gear used for harnessing a horse to a chariot.
Poesia, imagem e teoria: ressonâncias escatológicas a partir de Casaldáliga, Cerezo e Westhelle
Authors: Zeferino Jefferson , Fernandes Marcio Luiz , Dias Pinto Ana Beatriz
Published: February 2021

Dom Pedro Casaldáliga traduziu em poesia seu itinerário como bispo, missionário e teólogo engajado na luta contra as várias injustiças que testemunhou. O presente texto objetiva relacionar sua poesia com a imagética de seu confrade claretiano Maximino Cerezo Barredo, bem como perceber, a partir das reflexões escatológicas do teólogo e pastor luterano Vítor Westhelle, a teologia da cruz que subjaz sua obra. Como resultado, apresenta-se a importância dos mártires como transfundo de uma teopoética, teo-imagética e teologia da cruz que revelam o oposto no exposto (revelatio abscondita sub contraria specie) – a vida possível em meio à morte e ao sofrimento.
Consciências Saudáveis e Almas Enfermas: Posturas Éticas Religiosas em William James
Authors: Benevides Rodrigo Barbosa Gomes
Published: February 2021

Trata-se aqui de examinar as noções de Sick Soul e Healthy-Mindedness de acordo com William James em sua obra Varieties of Religious Experience: A Study in Human Nature (1902). O pragmatismo de James se preocupa com o fenômeno religioso em termos de utilidade de um conjunto de crenças que fundamentam ações no campo ético e, desse prisma,  James percebe a religião como ferramenta fundamental para o equilíbrio psíquico humano. Dito isso, o artigo apresenta os dois tipos básicos de postura ética aludidos, além de definir o que significa religião segundo James.
Religião e silenciamento do sofrimento: reflexões sobre morte e vida de mulheres em situação de violência
Authors: De Souza Sandra Duarte
Published: February 2021

Os dados relativos à morte e adoecimento de mulheres no Brasil e no mundo diretamente relacionados à violência de gênero atestam que há um imenso contingente de mulheres que, por força dessa violência, têm suas vidas abreviadas. Muitas nunca contaram essa experiência de dor ou, ao contarem, foram "aconselhadas" a mantê-la em segredo. A violência de gênero impõe às mulheres o silêncio sobre as suas dores. Seus sofrimentos são mantidos em segredo e guardados na casa, e a religião tem importante participação nisso, gerando a desmobilização da indignação contra a produção do sofrimento impetrado contra as mulheres. O presente artigo objetiva tratar do silenciamento das mulheres em situação de violência como mecanismo de dificultação do comprometimento social com suas vidas, e toma o caso específico da menina de dez anos que foi violentada e engravidada pelo tio no Espírito Santo para orientar essa discussão.
Some special families of holomorphic and Sălăgean type bi-univalent functions associated with Horadam polynomials involving a modified sigmoid activation function

Published: February 2021

The aim of this paper is to introduce some special families of holomorphic and S\u{a}l\u{a}gean type bi-univalent functions by making use of Horadam polynomials involving the modified sigmoid activation function $\phi(s)=\frac{2}{1+e^{-s} },\,s\geq0$ in the open unit disc $\mathfrak{D}$. We investigate the upper bounds on initial coefficients for functions of the form $g_{\phi}(z)=z+\sum\limits_{j=2}^{\infty}\phi(s)d_jz^j$, in these newly introduced special families and also discuss the Fekete-Szegö problem. Some interesting consequences of the results established here are also indicated.
