Authors: Sawant Shankar M , Ligade Vikas T
Published: December 2021

Secure communication network is the demand of today’s transportation due to excess number of vehicles and limitation to the existing communication protocol. This Paper discusses the secure communication protocol between the vehicles and the detection and prevention of the Sybil attack. Fake node request, multiple routing entries these are the common example of Sybil attack which can be detected and prevented using existing proposed method. Virtual nodes are created and messages are sent to nodes. The proposed method detects the identity of received message and number of fake entries of that particular massage in the routing buffer. If messages are validated then communication is possible otherwise request is terminated. Results showed that the existing proposed method is able to detect and prevent Sybil attack by maintaining single node identity.

Published: December 2021

Electrodeposition techniques is used for the deposition of nickel oxide thin film electrodes. In the present work, we report electrodeposition of nickel oxide thin film on the conducting stainless steel (SS) substrates for the application of electrochemical supercapacitor. X-ray diffraction confirms simple cubic crystal structure with polycrystalline nature of the deposited NiO sample that exhibits hydrophilic nature confirmed from the wettability study. The Scanning Electron Microscope (SEM) observed dense with cracky morphology. UV spectrum exhibits 3.55eV band gap of samples. The capacitive characteristics of the deposited thin film are investigated in 1M KOH electrolyte using cyclic voltammetry (CV). The supercapacitive properties of NiO are strongly affected by the scan rate. The maximum specific capacitance obtained is 162 F/g at 2 mV/s scan rate.
Quantum Mechanics and Nanotechnology

Published: December 2021

In quantum physics it is important that classical molecular dynamics studies of nanomachines may not give an accurate representation of their performance. Luckily another strategy, interior facilitate quantum Monte Carlo, a further developed method for processing quantum mechanical ground-state energies and wavefunctions, has the possible ability to demonstrate these frameworks. Some significant models show that the quantum ground state for some body frameworks like those of interest in nanotechnology has a subjectively unexpected construction in comparison to that got from a sub-atomic elements computation which displayed confusion and gross insecurities at energies of just a small amount of the ground-state energy. This outcome projects vulnerability on the unwavering quality of utilizing the sub-atomic elements strategy to ascertain the construction or some other dynamical amount pertinent to nanotechnology.

Os tempos em que vivemos são de pura atualização, simultaneidade e racionalidade Este é um convite a todos os que se inquietam, problematizam e exorcizam seus fantasmas através da performance. Talvez o contato com as energias ancestrais possam nos auxiliar a entender melhor eventos de neofascismo abrangente e global. O trabalho de Ayrson Heráclito mostra a relação entre o artista, seu corpo e suas possibilidade no cuidado do contexto, dos espaços de convivência.. Segundo Mariana Tessitore: “Praticante do candomblé há mais de vinte anos, Ayrson Heráclito acredita na arte como uma forma de cura. Para o artista baiano, é preciso “exorcizar os fantasmas da sociedade colonial” que ainda assombram o País. Em suas performances, vida, arte e religião se misturam num mesmo caldeirão, onde também entram alimentos da cultura baiana como o açúcar, a carne de charque e o dendê.
ConvChrome: Predicting Gene Expression Based on Histone Modifications
Using Deep Learning Techniques
Authors: Hamdy Rania , Maghraby Fahima A. , Omar Yasser M.K.
Published: December 2021

Background:

Gene regulation is a complex and dynamic process that not only depends on
the DNA sequence of genes but is also influenced by a key factor called epigenetic mechanisms. This
factor, along with other factors, contributes to changing the behavior of DNA. While these factors cannot
affect the structure of DNA, they can control the behavior of DNA by turning genes "on" or "off,"
which determines which proteins are transcribed.

Objective:

This paper will focus on the histone modification mechanism; histones are the group of proteins
that bundle the DNA into a structural form called nucleosomes (coils); The way these histone proteins
wrap DNA determines whether or not a gene can be accessed for expression. When histones are
tightly bound to DNA, the gene is unable to be expressed, and vice versa. It is important to know histone
modifications’ combinatorial patterns and how these combinatorial patterns can affect and work
together to control the process of gene expression.

Methods:

In this paper, ConvChrome deep learning methodologies are proposed for predicting the gene
expression behavior from histone modifications data as an input to use more than one convolutional
network model; this happens in order to recognize patterns of histones signals and interpret their spatial
relationship on chromatin structure to give insights into regulatory signatures of histone modifications.

Results and Conclusion:

The results show that ConvChrome achieved an Area under the Curve (AUC)
score of 88.741%, which is an outstanding improvement over the baseline for gene expression classification
prediction task from combinatorial interactions among five histone modifications on 56 different
cell types.

Ring
Authors: Amssayef Ayoub , Bouadid Ismail , Eddouks Mohamed
Published: December 2021

Aims:

The study aimed to assess the inhibitory effect of Vitamin C on angiotensin-converting
enzyme 2.

Background:

Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory
syndrome coronavirus 2 (SARS-CoV-2), which uses angiotensin-converting enzyme 2 (ACE-II)
as the first route to infect human cells. Accordingly, agents with potential inhibition of ACE-II receptors
might be effective in the prevention and management of COVID-19.

Objective:

The goal of this work was to assess the possible inhibitory effect of ACE-II on ascorbic
acid using an ex vivo approach based on the inhibition of diminazene-induced vasorelaxation.

Material and Methods:

In the present study, diminazene was used as a known specific inhibitor
of ACE-II. Then, the vasorelaxant effect of ascorbic acid on diminazene-induced relaxation was examined
using isolated aortic rings. All experiments of this study were evaluated on isolated aortic
rings precontracted by epinephrine.

Results:

The results confirmed that diminazene-induced vasorelaxation in a dose-dependent manner.
More interestingly, ascorbic acid inhibited diminazene-induced vasorelaxation in a dose-dependent
manner.

Conclusion:

This investigation provides valuable experimental proof of the efficacy of ascorbic
acid (Vitamin C) on inhibiting ex vivo vascular angiotensin-converting enzyme II, which is known
among the pharmacological targets of anti-COVID-19 drugs.

Published: December 2021

Introduction:

There has been an increasing number of studies that have evidenced the profile of male morbidity and mortality, their causes and related consequences, and their association with the low demand and men's permanence in the services offered in Primary Health Care (PHC).

Objective:

The objective of the study was to map the literature on men's health situation in Primary Health Care.

Methods:

A scoping review, according to the Joanna Briggs Institute protocol, with the PCC acronym (P – men, C – health situation, C – in primary care), was conducted in the Medline/Pubmed, COCHRANE, Web of Science, SCOPUS, Science Direct, LILACS, BDENF, MEDCARIBE, and SciELO databases, using the descriptors “Men”, “Men's Health”, “Health Services Needs and Demand”, “Primary Health Care” in three information sources (EBSCO, PubMed and SciELO).

Results:

Men's health situation in Primary Health Care is defined by the influence of the social construction of the masculinities and cultural aspects in the adoption of health care behaviors and practices, in the way in which men present their health complaints, demands, and needs, and establish bonds with the health professionals and the services.

Conclusion:

There is a number of sociocultural factors inherent to masculinities, institutional factors of the services' organization, and relational factors of men with the health professional that intervene together with the health situation.

Published: December 2021

In this paper, we put forward a semantic analysis of constructions of prepositional phrases introduced by the preposition para with a locative meaning combined with the verbs ser, estar and ficar. In this proposal, we characterise these constructions regarding the properties individual-level/ stage-level, modal reading, and vagueness of the location, as well as restrictions imposed on the subject related to some lexical semantic features, in particular [movable] and [animated] features. Additionally, we contrast these constructions to the ones introduced by the preposition em (typically locative), revealing to what extent they differ from each other.
A construção da identidade da mulher num acórdão sobre violência doméstica
Authors: Pinto Alexandra Guedes
Published: December 2021

In this paper we propose to demonstrate the analytical and critical potential of Discourse Studies for understanding identity constructs in a judicial decision on domestic violence.Taking as reference the concept of ideology in the sociocognitive framework (Van Dijk, 1995), that allows linking ideology and discourse, and using enunciative-pragmatic analytical categories, we will analyse certain aspects of a judicial decision, which demonstrate how the discourse structures favour a stigmatising and blaming representation of the woman victim of domestic violence and the consequent excuse and legitimisation of violence against her.The object of analysis will be a decision of the Court of Appeal of Porto, Portugal, issued on October 11, 2017, concerning a domestic violence lawsuit, in which the adultery of the assaulted woman is an argument for excusing the violence exerted by the aggressors.To implement our study, we will detach and analyse the linguistic means used to represent the actors involved; the predications attributed to them and the verbal processes in which they participate (Reisigl & Wodak, 2009). We will also detach and analyse instances of doxainvocation and evidentiality, occurrences of strong evaluative modality and mechanisms of illocutionary reinforcement, as strategies for argumentation and legitimisation.
Construções reflexiva, recíproca e média de clítico nulo no português brasileiro reconceptualização de eventos e emergência de uma nova construção
Authors: Silva Augusto Soares da , Afonso Susana
Published: December 2021

tuguese se constructions, posited in the transitive continuum, have a constructional counterpart in which the clitic is absent. The null clitic construction, observed in all the seconstructions (i.e. reflexive, reciprocal, middle, anticausative, passive and impersonal) is more frequently used in Brazilian Portuguese (BP) than in European Portuguese (EP). The phenomenon has largely been studied from a morphosyntatic lens or as a result of an ongoing deletion of clitics in BP, shying away from the possible implications in terms of the semantic differentiation between overt and null se constructions. This chapter focuses on reflexive, reciprocal and middle se constructions and aims to investigate what factors determine the choice between overt seconstructions and their null counterpart. Based on an extensive usage-feature and profile-based analysis, and using multivariate statistical methods, we show that reflexive, reciprocal and middle null se constructions are associated with a reconceptualization of an event as non-energetic or absolute, profiling the result of the event. On the other hand, the overt counterpart profiles the moment of change, construing the event as energetic. Reflexive and reciprocal constructions are more frequently encoded by an overt se construction whereas middle construction (in all its subcategories) is more frequently encoded by the null se construction. The study concludes that null reflexive, reciprocal and middle se constructions are new constructions semantically differentiated from overt se constructions, which, we argue, has wider implications, namely for reconceptualization of voice patterns in BP which tend towards ergativization.

The clean water crisis is increasing along with the increasing human population. Sea water is one of the largest water sources that can be utilized on the earth. However, the high salt concentration dissolved in seawater must be treated before it can use. Desalination is the directly technology for treating seawater with PVDF-TiO2 hollow fibre membrane via pervaporation process. The aim of this research was to determine the performance of PVDF-TiO2 hollow fibre membrane against variations in feed temperature in the artificial seawater pervaporation process. Method for fabrication membrane is using dry-wet spinning method. The result showed that the highest flux permeat occurred at feed temperature of 60ºC, namely 8.96 kg.m-2.h-1 with salt rejection > 92.86%. The result via SEM showed that of the membrane surface morphology, there is a white spot on the membrane surface is TiO2 because the dope solution is too thick. The PVDF-TiO2 hollow fiber membrane in this research is can be applied for seawater pervaporation.

Published: December 2021

Raw materials for buildings and construction account for more than 35% of global primary energy use and nearly 40% of energy-related CO2 emissions. The Intergovernmental Panel on Climate Change (IPCC) emphasized the drastic reduction in GHG emissions and thus, wood products with very low or negative carbon footprint materials can play an important role. In this study, a cradle-to-grave life cycle assessment (LCA) approach was followed to quantify the environmental impacts of laminated strand lumber (LSL). The inventory data represented North American LSL production in terms of input materials, including wood and resin, electricity and fuel use, and production facility emissions for the 2019 production year. The contribution of cradle-to-gate life cycle stages was substantial (>70%) towards the total (cradle-to-grave) environmental impacts of LSL. The cradle-to-gate LCA results per m³ LSL were estimated to be 275 kg CO2 eq global warming, 39.5 kg O3eq smog formation, 1.7 kg SO2 eq acidification, 0.2 kg N eq eutrophication, and 598 MJ fossil fuel depletion. Resin production as a part of resource extraction contributed 124 kg CO2 eq (45%). The most relevant unit processes in their decreasing contribution to their cradle-to-grave GW impacts were resource extraction, end-of-life (EoL), transportation (resources and product), and LSL manufacturing. Results of sensitivity analysis showed that the use of adhesive, consumption of electricity, and transport distance had the greatest influences on the LCA results. Considering the whole life cycle of the LSL, the final product stored 1,010 kg CO2 eq/m³ of LSL, roughly two times more greenhouse gas emissions over than what was released (493 kg CO2 eq/m³ of LSL) from cradle-to-grave. Overall, LSL has a negative GW impact and acts as a carbon sink if used in the construction sector. The study results are intended to be important for future studies, including waste disposal and recycling strategies to optimize environmental trade-offs.

Authors: Povey Josie , Sweet Michelle , Nagel Tricia , Lowell Anne , Shand Fiona , Vigona Jahdai , Dingwall Kylie M
Published: December 2021

Background

Digital mental health tools can promote access to culturally safe early intervention mental health services for Aboriginal and Torres Strait Islander young people. Participatory design methodology facilitates user engagement in the co-design of digital resources. However, several challenges have been identified that limit the methodological rigor of this approach.

Objective

This paper aims to present an in-depth account of the second phase of participatory design in the development of the Aboriginal and Islander Mental Health Initiative for Youth (AIMhi-Y) app.

Methods

A first idea storyboard, generated from a formative phase of the AIMhi-Y project, was refined through a series of youth co-design workshops and meetings. A narrative review of the literature, 6 service provider interviews, and engagement with an expert reference group also informed the design process. Generative design activities, storyboarding, discussions, and voting strategies were used.

Results

The participatory design process identified the app features preferred by young people and service providers and assessed their alignment with current recommendations from the scientific literature. Findings from the co-design process are presented across 9 app characteristic domains. Integration of findings into app design proved complex. Although most preferred features identified by young people were included to some degree, other inclusions were restricted by budget, time, and the need to integrate best practice recommendations. A process of prioritization was required.

Conclusions

Participatory design is often cited in the development of digital mental health resources; however, methods are diverse and often lack detailed descriptions. This study reports the outcomes and strategies used to determine priorities in the second phase of the development of the AIMhi-Y app. We provide an example and the key learnings to inform others seeking to use participatory design with a similar cohort.

Authors: Gunter Dane , Puac-Polanco Paulo , Miguel Olivier , Thornhill Rebecca E. , Yu Amy Y. X. , Liu Zhongyu A. , Mamdani Muhammad , Pou-Prom Chloe , Aviv Richard I.
Published: December 2021

BACKGROUND

Data extraction from radiology free-text reports is time-consuming when performed manually. Recently, more automated extraction methods using natural language processing (NLP) are proposed. A previously developed rule-based NLP algorithm showed promise in its ability to extract stroke-related data from radiology reports.

OBJECTIVE

We aimed to externally validate the accuracy of CHARTextract, a rule-based NLP algorithm, to extract stroke-related data from free-text radiology reports.

METHODS

Free-text reports of CT angiography (CTA) and perfusion (CTP) studies of consecutive patients with acute ischemic stroke admitted to a regional Stroke center for endovascular thrombectomy were analyzed from January 2015 - 2021. Stroke-related variables were manually extracted (reference standard) from the reports, including proximal and distal anterior circulation occlusion, posterior circulation occlusion, presence of ischemia, hemorrhage, Alberta stroke program early CT score (ASPECTS), and collateral status. These variables were simultaneously extracted using a rule-based NLP algorithm. The NLP algorithm's accuracy, specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV) were assessed.

RESULTS

The NLP algorithm's accuracy was >90% for identifying distal anterior occlusion, posterior circulation occlusion, hemorrhage, and ASPECTS. Accuracy was 85%, 74%, and 79% for proximal anterior circulation occlusion, presence of ischemia, and collateral status respectively. The algorithm had an accuracy of 87-100% for the detection of variables not reported in radiology reports.

CONCLUSIONS

Rule-based NLP has a moderate to good performance for stroke-related data extraction from free-text imaging reports. The algorithm's accuracy was affected by inconsistent report styles and lexicon among reporting radiologists.

Kết quả cho thấy 100% nông dân khảo sát sử dụng hoạt chất PBZ cho lúa nhằm giảm đổ ngã. Hai sản phẩm thương mại được sử dụng phổ biến nhất là Bidamin 15WP và Bonsai 10 WP với lượng cao hơn nhiều lần so với khuyến cáo. Hàm lượng PBZ lưu tồn trong 10 mẫu đất dao động từ 0,09 đến 1,11 mg/kg đất. Bên cạnh đó, nghiệm thức sử dụng chế phẩm vi khuẩn giúp hủy hoàn toàn lượng PBZ lưu tồn trong đất sau 35 ngày thí nghiệm, tuy nhiên không giúp gia tăng năng suất nếp so với nghiệm thức không sử dụng chế phẩm vi khuẩn sau 1 vụ thí nghiệm. Như vậy, chế phẩm vi khuẩn phân hủy PBZ có hiệu quả phân hủy hoạt chất PBZ trong đất lúa.
Collaborative Annotation as a Teaching Tool
Authors: Bauer Matthias , Lahrsow Miriam
Published: December 2021

The guidelines presented here were developed in a seminar aimed at M.A. and advanced B.A. students. They are based on

narratological theories by Marie-Laure Ryan, Gérard Genette, William Nelles, Ansgar Nünning, John Pier, and Viveca Füredy. Our contribution focuses on how collaborative annotation tasks can be used in university seminars, especially in the context of teaching students how to critically assess and compare theoretical frameworks and definitions. We also highlight the students’ impression that developing and using annotating guidelines improved their close-reading skills and that the task sensitised them to some of the core challenges of distant reading (e.g. questions of ambiguity and interpretation).
El yo situado y relacional en Nishida y Watsuji: una aproximación desde el paradigma de la intimidad de Kasulis
Authors: Bouso Raquel
Published: December 2021

En su obra Intimacy or Integrity: Philosophy and Cultural Difference (originalmente 1988 Gilbert Ryle Lectures, publicada en 2002), Thomas P. Kasulis identifica dos tipos de orientaciones “intimidad” e “integridad” que condicionan tanto las relaciones interpersonales como nuestra relación con el mundo. Si bien ambas orientaciones se pueden hallar tanto en las tradiciones filosóficas occidentales como en las asiáticas, puede decirse que la primera predomina en buena parte de la filosofía japonesa. A partir del paradigma de la intimidad descrito por Kasulis, examinaremos dos creaciones conceptuales de Nishida Kitarō (1870-1945) y Watsuji Tetsurō (1889-1960) respectivamente, el “yo como lugar” y el “ambiente geocultural”. De este modo, mostraremos cómo emerge un modo de comprender el “yo” como algo situado y relacional que nos permite pensar un modo de ser ecológico-comunitario.

Authors: Leciejewski Zbigniew , Cudziło Stanisław
Published: December 2021

Progress in the development of solid propellants and knowledge determining the possibility of increasingly detailed analysis of phenomena occurring during the process of propelling projectiles are the main factors in the development of powders and gun propellant systems. The growth of potential ammunition and powder propellant systems is focused on improving the energetic, ballistic and operational characteristics of currently used powders and on searching for new propellants with a more environmentally friendly chemical composition (so-called green propellants). This paper presents an analysis of the possibilities in propellant systems development in the 21st century, from the internal ballistics perspective. At present, the most promising, from the tactical and technical point of view, are the propellant systems with layered powders (for a classic propellant system solution) and ETC (Electrothermo-Chemical gun) systems.

Arab Journal of Plant Protection, 39(4): 231-240. https://doi.org/10.22268/AJPP-39.4.231240 Fusarium wilt disease caused by Fusarium oxysporum f. sp. ciceris is one of the diseases that cause significant economic losses to the chickpea crop around the world, as infection with FOC can occurs during the different stages of plant growth. One of the best approaches to reduce the damage caused by FOC is by using resistant chickpea varieties. Hence, this study aimed to determine the physiological races of 25 FOC isolates collected from 20 agricultural sites belonging to six regulatory zones in the Al-Ghab region in Syria, based on their pathogenicity on 13 differential chickpea cultivars (C-104, JG -74, CPS-1, BG-215, BG-212, WR-315, Anniger, Chaffa, ILC482, L-550, K850-3/27, UC-27). The study was carried out during 2020 at the Agricultural Scientific Research Center in Al-Ghab. The results obtained showed that the tested isolates belong to races 0, 1B/C, 2, 3, 5, and 6. This is the first report of races 2 and 3 in Syria, and each of them constituted 28% of the total tested isolates, whereas 24% of the isolates were represented by race 0, and both races 5 and 1B/C occurred at 8% frequency, and race 6 included one isolate obtained from Abu Faraj site.

Evaluación de las condiciones predisponentes a enfermedades en granjas porcinas a pequeña escala en un ambiente urbano en el noroeste de la Ciudad de México
Authors: Martínez Gamba Roberto , Ramírez Hernández Gerardo
Published: December 2021

El objetivo del trabajo fue desarrollar y aplicar un instrumento para identificar las condiciones predisponentes a la presentación de enfermedades en 12 granjas porcinas a pequeña escala en un ambiente urbano. Se analizó el porcentaje de puntos negativos obtenidos de manera general y por tipo de granja en función a su producción, engorda (T1) o ciclo completo (T2), donde el mayor porcentaje fue para T1 (50 %) y para T2 (66.0 %). Del mismo modo se analizaron los datos para comparar a las granjas T1 y las T2 en relación con los porcentajes de cada sección que integra la encuesta, donde solo se encontró diferencia en la sección “estado de salud” (P<0.0001). La relación entre la densidad de población por m2 con respecto al porcentaje máximo de puntos alcanzados por granjas, no mostró diferencia (R2, 0.03; P=0.854). No se encontró correlación entre el porcentaje de puntos obtenidos con el número de animales (R2, 0.13; P=0.722). En relación al porcentaje promedio por sección por tamaño de la población, solo se detectó diferencia en la sección “alimentación” (P<0.0006), indicando que las granjas con 10 a 40 cerdos obtuvieron menos puntos en esta sección. Se concluye que la metodología para la evaluación de las condiciones predisponentes a enfermedades en este tipo de granjas resultó ser aplicable. Se determinó que el tamaño de las granjas y la densidad de población, no son un factor predisponente en estas granjas, pero las condiciones predisponentes a la presentación de enfermedades difieren entre granjas de ciclo completo y engorda.

Infections caused by Streptococcus suis (S. suis) pose a problem for the pig industry worldwide. Pigs often carry multiple serotypes of S. suis in the upper respiratory tract, where S. suis is frequently isolated from. The clinical diagnosis of the infection is presumptive and is generally based on clinical signs, the age of the animal and macroscopic lesions. In the laboratory, identification of S. suis is performed biochemically, and then, serotyping is performed with antisera to determine the serotype, but these tests can be inconclusive. To date, there are few studies that have documented the presence and diversity of S. suis serotypes in Mexico. In the present study, it was characterized S. suis strains from Mexican pig farms using molecular approaches; samples were first processed by PCR of the gdh gene to detect S. suis. Positive samples were then subjected to a two-step multiplex PCR (cps PCR) to detect and characterize each strain; the first step consisted of a grouping PCR and the second step consisted of a typing PCR. The serotypes detected in the pig farming areas of Mexico included 1/2, 2, 3, 5, 7, 8, 9, 17, and 23. These findings are important for the characterization of serotypes present in Mexico and for outbreak prevention.

La propagación eficiente de especies vegetales con alto potencial alimenticio juega un papel fundamental en su adopción y utilización por parte de los productores. Es importante, por tanto, desarrollar métodos económicos y rápidos para el establecimiento exitoso de sistemas más productivos. Con el objetivo de conocer algunos aspectos reproductivos de diferentes genotipos destacados de T. diversifolia y así favorecer su propagación y mejorar su uso en la alimentación animal, se evaluó su potencial de germinación, producción de semilla y duración del ciclo reproductivo. Se usaron 42 parcelas en un diseño de bloques completos al azar con siete genotipos de T. diversifolia y dos niveles (sin y con fertilización). Los genotipos tuvieron diferencias en todas las variables agronómicas y de producción de semilla a excepción del tiempo de secado de aquenios y en el porcentaje de semillas rudimentarias (P<0.01). Con relación a la producción de semilla sexual, la fertilización tuvo efecto significativo (P<0.05) y en general incrementó el tiempo de las fases evaluadas. La mayor producción de semilla se dio en los genotipos 7 y 5 y el porcentaje de germinación tuvo diferencias significativas entre genotipos y entre los tratamientos pre-germinativos (P=0.0001) con mayores porcentajes en los genotipos 3 y 6. Se concluye que a pesar de la baja viabilidad de la semilla sexual de T. diversifolia, existen genotipos con un mayor potencial de producción de semilla y porcentaje de germinación, parámetros que pueden ser mejorados por medio de tratamientos pre-germinativos y el uso de fertilizantes.
Estado del conocimiento y amenazas del humedal marino de Chamiza (41°S): sitio de importancia internacional para la conservación de aves playeras migratorias en el sur de Chile

Published: December 2021

Los humedales marinos de la Región de Los Lagos, en el sur de Chile, son reconocidos ecosistemas de importancia internacional para la conservación de aves playeras migratorias. Sin embargo, la mayoría de estos sitios se encuentra desprotegido, requiriendo urgentemente avanzar en su protección y gestión. Por ello, el objetivo del presente trabajo es realizar un diagnóstico sobre el estado del conocimiento del humedal marino de Chamiza (41°30’S; 72°50’W), mediante revisión bibliográfica, junto con desarrollar de forma participativa la identificación y priorización de amenazas para la conservación de aves playeras migratorias en el sitio. Los estudios publicados sobre el humedal marino de Chamiza (n= 24), abarcan documentos desde el año 1987 hasta 2019. La mayoría se han enfocado en aves acuáticas, seguido por los invertebrados marinos que habitan la planicie intermareal. El humedal marino de Chamiza posee un importante valor de conservación para aves playeras migratorias, manteniendo más del 10% de la población de Limosa haemastica que se reproduce en Alaska, y que cada año migra hacia los humedales marinos del sur de Chile. Se identificaron 14 amenazas para la conservación de aves playeras migratorias en el humedal marino de Chamiza. Las principales amenazas se asocian con el efecto de la urbanización residencial, por favorecer la abundancia de perros y generar residuos sólidos y líquidos en el ambiente. En general, los resultados apoyan la idea de una red de humedales marinos insulares y continentales que interactúan entre sí, mediante las aves playeras migratorias.

Authors: María Vanessa Lencinas , Francisco José Zamora , Guillermo José Martínez Pastur
Published: December 2021

Aegorhinus nodipennis (Curculionidae) es una especie nativa de la Patagonia continental de Argentina y Chile, considerada plaga de importancia en cultivos frutihortícolas de Chile. En esta nota se describe su detección y los daños generados en forestaciones y huertas de cascos de estancias de Tierra del Fuego argentina (Ea. Sara y Ea. Viamonte), causando la mortalidad de añosos árboles exóticos de madera blanda (principalmente abedules, sauces y serbales), de valor ornamental paisajístico o en cortinas forestales, desde el año 2017 hasta el presente. Se discute el potencial de invasión y afectación de los ecosistemas nativos de la región, así como de profundizar los estudios sobre su comportamiento en esta región, y la importancia de realizar monitoreos y control para la preservación de la vegetación nativa y la de cascos de estancias, de importancia histórica y cultural para la población fueguina.

El objetivo de este artículo es analizar mediante el métodode regresión lineal simple, la relación del impacto que tienela precipitación y la cantidad de área sembrada frente a laproducción de arroz en el Departamento del Meta. Paraeste análisis se obtuvieron datos de precipitación proporcionados por el IDEAM y datos de área sembrada y producción de arroz obtenida de la información anexada delIV Censo Nacional Arrocero del año 2016, realizado por elconvenio FEDEARROZ-DANE. Los valores que se analizaron de estas tres variables fueron de los períodos semestrales comprendidos entre (1999 - 2017). Para el caso de laprecipitación se halló el promedio usando las medicionestotales semestrales de las estaciones pluviométricas ubicadas en el departamento del Meta. Después del análisis, seobtuvo como resultados que la producción de arroz es unavariable dependiente de la cantidad de área que se siembrey de la cuota pluviométrica como valor agregado, es decir, amayor cantidad de área sembrada y una buena pluviosidaden el ciclo productivo, mayor será la producción de arroz.

Accounting Firm Association Membership and Small Audit Firm Growth
Authors: Ahn Jaehan , Akamah Herita , Bills Kenneth L. , Saunders K. Kelli
Published: December 2021

In this study, we explore a topic of primary concern to small audit firms—attracting public audit clients. A potential avenue available to small audit firms to enhance their visibility and legitimacy among potential public audit clients is to join an association of accounting firms (ACAP 2008; GAO 2008). We examine whether small audit firms with accounting association membership have greater public clientele growth than their peer audit firms without association membership. We find that member firms experience public clientele growth as measured by number of clients and revenues audited. We find that this growth is impacted by both gaining new entrants to the audit market and winning over clients from competitors. Further, we find that the reputation of associations positively affects the clientele growth seen by member firms. In additional analyses, we also find some evidence of private client growth of association members using LexisNexis® Company Dossier data.
Is There a Dark Side to Societal Trust in Auditors' Going Concern Assessments?
Authors: Ahn Jaehan , Akamah Herita
Published: December 2021

Amidst heightened concern among U.S. and international regulators is the need to examine reasons why auditors are not issuing going-concern opinions (GCOs) to financially distressed clients who seem to warrant such opinions. We examine societal trust as one such reason, finding a lower incidence of GCOs with high societal trust. Moreover, we find that high societal trust is associated with fewer GCO Type I misclassifications, but more GCO Type II misclassifications. In addition, the association between societal trust and GCOs does not disappear for severely distressed clients, suggesting that auditors do not adequately perceive clients that warrant GCOs when the clients are in high trust countries, and illuminating a dark side to societal trust. Moreover, low litigation risk and auditor-management relationship longevity exacerbate this dark side of societal trust. Our study highlights how societal trust can have beneficial effects across multiple economic contexts while posing problems in the auditing context.

Dünyadaki koronavirüs hasta sayısı her geçen gün artmaktadır. Hastalığın ortaya çıkışının üzerinden bir seneden fazla zaman geçmesine rağmen istatistiklere göre henüz hasta sayısındaki zirve görülmemiştir. Hasta sayısındaki artışın zamana yayılması hastane doluluk oranlarının tehlikeli boyutlara ulaşmasını önlemek için önemlidir. Bu nedenle virüsü taşıyan bireylerin hızlıca teşhis edilerek hastalık geçene kadar toplumdan soyutlanmaları gerekmektedir. Bu çalışmada X-ray görüntüsü kullanılarak yapılabilecek hızlı hastalık teşhisi için kapsamlı bir yapay sinir ağı tabanlı model önerilmiştir. Koronavirüsün akciğerler dokularında yarattığı tahribattan yararlanılarak teşhis işlemi saniyeler içerisinde yapılabilmektedir. Çalışmaya konu olan model, X-ray görüntülerini ön-işlemlerden geçirerek iyileştirmekte ve çoğullamaktadır. DenseNet201, ResNeXt-101(32×8d), VGG-19bn ve Wide-ResNet101-2 ağları kullanılarak eğitim yapıldıktan sonra görüntüden Covid-19 pozitif veya negatif olarak teşhis konulmasını sağlamaktadır. Çalışmada elde edilen en iyi sonuç %94.79 genel doğruluk oranıyla ResNeXt-101(32×8d) ağı kullanılarak gerçekleştirilmiştir.
