GASTOS SOCIAIS E ACCOUNTING GIMMICKS: UMA PERCEPÇÃO DOS CICLOS POLÍTICOS ELEITORAIS NOS MUNICÍPIOS DO CENTRO-OESTE BRASILEIRO
Authors: Silva Nilton Oliveira da , De Souza Freire Fátima
Published: April 2021

Essa pesquisa objetivou verificar em que extensão as práticas de accounting gimmicks afetam as políticas fiscais e a execução dos gastos sociais durante os ciclos políticos eleitorais. Por meio de um modelo logit, foram analisadas as contas públicas dos 466 municípios da região centro-oeste brasileira em um painel desbalanceado no período de 2004 a 2017. Com uma especificidade singular, os municípios brasileiros têm apresentado dificuldades na manutenção de um desempenho fiscal eficiente. Uma abordagem teórica dos regimes fiscais enfatiza que a rigidez fiscal pela qual os governantes são conduzidos pode impulsionar práticas de manipulações contábeis, especialmente nos saldos do SFA (Stock-flow adjustment). Tais práticas visam melhorar os resultados orçamentários, a visibilidade política e a permanência no poder. Os achados permitiram corroborar parcialmente com a literatura de que há uma relação positiva entre as regras fiscais rígidas e as práticas de accounting gimmicks. Ainda foi possível constatar que situações de elevados índices de dependência financeira e de oportunismo político para reeleição são impulsionadores nas ocorrências dessas manipulações. Portanto, concluiu-se que a utilização dos gastos sociais, alinhados a uma abordagem teórica dos regimes fiscais rígidos e da Teoria dos Ciclos Políticos Eleitorais, é influenciada pelo comportamento oportunista dos gestores e pelas práticas de accounting gimmicks.
CICLO DE APRENDIZAGEM ADEPT E O DESEMPENHO ACADÊMICO EM CONTABILIDADE DE CUSTOS
Authors: Melo José Augusto Souza de , Tonin Joyce Menezes da Fonseca , Facci Nilson
Published: April 2021

O Ciclo de Aprendizagem Analysis of Diagnostic Exam Prompted Teaching (ADEPT) é uma metodologia de ensino e gestão de sala de aula desenvolvida por Shoulders e Hicks (2008). Esta abordagem implica na aplicação de avaliações diagnósticas que identificam o nível de conhecimento dos estudantes em um determinado tópico antes de serem examinados em uma avaliação somativa. O objetivo deste estudo foi verificar a relação entre a aplicação do Ciclo de Aprendizagem ADEPT e o desempenho acadêmico dos estudantes matriculados na disciplina de Contabilidade e Análise de Custos em uma Universidade Pública Estadual Paranaense. Para identificar a relação entre a aplicação dos exames diagnósticos e o desempenho acadêmico foi adotada uma abordagem quase-experimental em duas turmas da disciplina de Contabilidade e Análise de Custos. Foram definidos os grupos de tratamento e controle, em que a diferença principal entre eles foi a participação ou não em um exame diagnóstico do conhecimento com antecedência de uma semana em relação à prova que determinaria a nota do bimestre. Para análise dos dados coletados foi utilizado testes de médias (t de student) e regressão múltipla. Os resultados indicam uma relação positiva entre a aplicação de avaliações diagnósticas e o desempenho dos discentes. As evidências encontradas colaboram com as pesquisas de Shoulders e Hicks (2008) e de Thomas, Bell e Shoulders (2013), e amplia a literatura ao indicar que a aplicação do Ciclo de Aprendizagem ADEPT é efetiva na melhoria do desempenho acadêmico, mesmo quando aplicada em sala de aula, de maneira coletiva.
Weighted P-partitions enumerator
Authors: Pesovic Marko , Stojadinovic Tanja
Published: April 2021

To an extended generalized permutohedron we associate the weighted integer points enumerator, whose principal specialization is the f-polynomial. In the case of poset cones it refines Gessel?s P-partitions enumerator. We show that this enumerator is a quasisymmetric function obtained by universal morphism from the Hopf algebra of posets.
Crafting the JFK legend: How the Kennedy story is constructed and retold
Authors:   , Thomas Dwynwen A.
Published: April 2021

This thesis explores how the ambivalently multifarious Kennedy ‘stories’ of JFK as Icon or Myth are constructed and how its ‘telling’ has been profoundly influenced by authorial intent. In contrast with much of the Kennedy literature, that often blurs the two, the thesis therefore works with a strong distinction between ‘Icon’ as having wholly positive connotations and ‘Myth’ as a narrative which either falsifies or negatively debunks any pre-existing positive accounts of its subject matter.My focus on newspaper articles, in particular from The New York Times and The Dallas Morning News, arises from the familiarly powerful claim that journalists write ‘the first draft of history’, although the thesis also reaches beyond journalism. Crucial to the argument is E. H. Carr’s historiography and its contention that historical facts are selected and presented according to particular hypotheses utilized by historians of any stripe for their own particular purposes. The thesis uses J. L. Austin’s theory of speech acts to demonstrate how the telling of the Kennedy story has variously employed techniques not only supposedly just to describe his legacy (the locutionary speech act) but also a) to create a legacy (the illocutionary speech act) and b) to influence audience attitudes toward the legacy (the perlocutionary speech act).The malleability of the Kennedy story helps to explain the reason why there remains so many attempts to retell it. The thesis also opens up consideration as to why it is this particular story that so many still want to hear.
PERSONAL VALUES SCALE: BRAZILIAN ENTREPREUNERS’ STARTUPS SAMPLE VALIDATION
Authors: Frate Flavia , Correa Renata Martins , Carvalhaes Katia Astorino , Guevara Arnoldo De Hoyos
Published: April 2021

This study aims to validate the personal values that push up entrepreneurs to idealize startups in Brazil. The research respondents are incubated at SEBRAE’s centers, a Brazilian support service for micro and small companies, in Alto do Tietê region, São Paulo, Brazil. The empirical quantitative research used the PQV values scale, the Portrait Questionnaire Value, which evaluates individual values based on Schwartz's model of human values. Continuing the studies of this author, this research is made considering ten types of personal values and four areas that present the following indicators: 1. Conservation (conformity, tradition and security); 2. Openness to change (self-direction, stimulation and hedonism); 3. Self-enhancement (achievement and power); 4. Self-transcendence (benevolence and universalism or philanthropy). The scale contains 40 statements and describes people with different aims, interests and aspirations. A multidimensional scale (MDS), with the aid of R software, analyzed the results in order to position the values dimensions. The hypothesis that the predominant latent values are from the openness to change area was confirmed. Thus, the conclusion is that personal values related to openness to change, such as: self-determination, stimulation and hedonism or pleasure, are latent values in the entrepreneurs interviewed. These values are related to freedom, creativity, audacity and pleasure in their projects.
ADOPTION OF KNOWLEDGE MANAGEMENT IN PAKISTAN: AN INVESTIGATION OF CRITICAL SUCCESS FACTORS
Authors: Ali Qamar , Bajwa Sami Ullah , Rehman Khaliq Ur
Published: April 2021

Although, knowledge has been recognized as a key business asset, firms are still in the infancy stages of comprehending the practical implications of knowledge management. Developing countries are widely believed to be falling far behind in competitiveness and socio-economic development, due to their inability to develop capacities to enable themselves to take part in the emerging global networks of knowledge creation. There is a dire need for a more organized and purposeful study, on critical success factors for knowledge management adoption in developing countries like Pakistan. However, no research, so far, has been conducted to empirically investigate a detailed list of CSFs for KM adoption in Pakistan. This paper evaluates and disseminates the findings of a self-administered survey to investigate the critical success factors for the implementation of KM in banking sector of Pakistan. A survey questionnaire having 11 factors, consisting 66 items is adopted in this study, which is statistically tested for its validity as well as reliability. Data are collected from banking officials. The level of importance, as well as the ranking list of the critical success factors for KM adoption is statistically examined. This paper provides a priority list of CSFs—figured out in order of their importance—for KM adoption in the banking sector of Pakistan. Human resource management, motivational aids, and processes and activities are found to be the most important, while measurement and organizational infrastructure are found to be the least important factors, perceived by the bankers.
Susceptibilidade natural à erosão nas áreas de pastagem da sub-bacia hidrográfica do ribeirão Santa Cruz, no município de Muniz Freire (ES)
Authors: Fiorese Caio Henrique Ungarato
Published: April 2021

Livestock, although it has significant economic relevance, is the cause of several problems related to erosion. This fact becomes even more worrying in the context of a hydrographic basin. Thus, the objective of this work was to assess the natural vulnerability to erosion in the pasture areas of the hydrographic sub-basin of the Santa Cruz stream (HBSCS), in order to support improvements related to soil conservation associated with local economic productivity. The procedures took place with the aid of the ArcGIS® geographic information system. The cartographic databases were the websites of GEOBASES, the National Water Agency and the Jones dos Santos Neves Institute. Initially, HBSCS was delimited to later acquire features (vector files) related to the location of pastures covered by HBSCS. The Universal Soil Loss Equation was used to estimate potential erosion. For this, the following data were obtained: erosivity, erodibility, ramp length and slope. Erosion was mapped, quantified and classified. The natural intensity of erosion ranges from 0 ton/ha.year to 6814 ton/ha.year, with an arithmetic mean of 569.740 ton/ha.year and standard deviation equal to 345.013 ton/ha.year. The class with the highest intensity is “moderate to strong”. However, when combined, the “moderate to strong” and “strong” classes comprise 65.666%. The lower intensity classes, “weak” and “moderate”, together, represent only 33.652%. The values can be attributed, mainly, to the ignorance on the part of the rural producers about the most favorable places for the installation of pastures. Therefore, it is extremely necessary to adopt measures favorable to soil conservation, such as the correct management of livestock, especially in areas with a greater erosive tendency. It is expected that studies with a similar theme will continue, considering, for example, the influence of management on HBSCS erosion.

The erosion wear mechanism of liquid-solid two-phase high pressure manifold tee pipes
Authors: Zhang J. , Zhu P. , Zhang H. , Lv L.
Published: April 2021

The wall thickness of pressure pipe is often thinned due to the erosion wear, which leads to pipe failure and even safety accidents. In particular, the tee pipe is more prone to be erosive as a key component of transferring fluid with particles. Therefore, the erosion wear mechanism of high pressure manifold tee pipe based on liquid-solid two-phase flow is studied in this paper. Firstly, the standard tee pipe geometry model is established and the grid is divided. And then grid number independence is verified by the percentage difference. According to the structural characteristics of tee pipe, the wear of the inner wall under four different port combinations is predicted. In addition, the relationship between erosion rate and wall shear stress is further analyzed by fluid velocity, particle diameter and mass flow rate. Double tee pipes geometry model was established to explore the erosion wear on the inner walls. The effects of assembly length and different port combinations on erosion wear were discussed respectively. When the inlets are fixed, the wall shear stress distribution of the downstream tee pipe is mainly affected by the outlets. The assembly length mainly affects the erosion rate of the downstream tee pipe.

Tengsl sem leikskólabörn mynda við önnur börn og kennara sína eru lykilatriði í námi þeirra og vellíðan. Myndist góð tengsl skapast sú tilfinning að tilheyra í leikskólasamfélaginu. Hugtakið fullgildi vísar til þátttöku, félagslegra tengsla og þeirrar tilfinningar að tilheyra. Rannsóknir sýna að börn af erlendum uppruna geta orðið utanveltu í jafningjahópi og að stuðningur starfsfólks getur skipt sköpum við að stuðla að fullgildi barna með erlendan bakgrunn.

through Art and Accompanied Narratives

Presenter: Alaa Azan, Institute of Interdisciplinary Studies, Child Studies program

Faculty Supporter: Carol Rowan

 

Recent scholarly writing concerning refugees and education are sometimes drawn towards deficit- perspectives. As a result, refugee families and children could be viewed as “Subjects of trauma” and “Vulnerable victims.” The dominant deficit-discourse is perpetuated by focusing on themes of war, trauma, and fear when examining children’s drawings. The current study aims to move away from this problem- based discourse and instead employ a strength-based approach to analyze the meaning of the school-based experiences of refugee students in Canada. The study will investigate the research question: How do a small group of refugee children, depict their lived school experiences in two Ottawa area community centers through drawings and verbal descriptions? The purpose of the study is to open space for discussions on the ways refugee students are viewing their schooling in Canada, building the capacity of educators, policymakers and everyone concerned with refugee’s success to serve them better. Guided by a post-structural theoretical framework, the study used drawings and descriptions to document refugee children schooling experience. Arabic speaking refugee students ages 6-12 were asked to draw “a typical day at school.” 18 Students were recruited from two community centers in Ottawa. The drawing activity took 20-30 minutes. Thematic analysis was applied to the data to help organize the emerging findings from the drawings and the verbal data. The results demonstrated the domination of themes on play and learning as reflecting the schooling experience and revealed the overall positive outlook of the participants towards their schooling in Canada.
The Debate on Gun-Control
Authors: Geng Serena (Ai Nuo)
Published: April 2021

This presentation will begin by looking at the concept of deep disagreements and how it relates to the current debate on gun-control in America. Deep disagreements occur when people do not share the same underlying assumptions as coined by  Fogelin (1985). Next, I will examine the issue of gun-control through the two main arguments of the pro-gun party: that guns make America a safer place and that the U.S. Constitution grants American citizens the right to bear arms. I will then offer anti-gun arguments against these claims as well as independent anti-gun claims in an attempt to rationally reconcile the two sides. Lastly, I will conclude with the assertion that the debate on gun-control is in fact rationally reconcilable.
A Variation of 3D Printer Machinery for Spectroscopic Tissue Analysis
Authors: Connolly Laura
Published: April 2021

PURPOSE: Raman Spectroscopy is amongst several optical imaging techniques that have the ability to characterize tissue non-invasively. To use these technologies for intraoperative tissue classification, fast and efficient analysis of optical data is required with minimal operator intervention. Additionally, there is a need for a reliable database of optical signatures to account for variable conditions. We developed a software system with an inexpensive, flexible mechanical framework to facilitate automated scanning of tissue and validate spectroscopic scans with histologic ground truths. This system will be used, in the future, to train a machine learning algorithm to distinguish between different tissue types using Raman Spectroscopy.

 METHODS: A sample of chicken breast tissue is mounted to a microscope slide following a biopsy of fresh frozen tissue. Landmarks for registration and evaluation are marked on the specimen using a material that is recognizable in both spectroscopic and histologic analysis. The slides are optically analyzed using our software. The landmark locations are extracted from the spectroscopic scan of the specimen using our software. This information is then compared to the landmark locations extracted from images of the slide using the software, ImageJ.

RESULTS: Target registration error of our system in comparison to ImageJ was found to be within 1.1 mm in both x and y directions.

CONCLUSION: We demonstrated a system that can employ accurate spectroscopic scans of fixed tissue samples. This system can be used to spectroscopically scan tissue and validate the results with histology images in the future
Comparison of Pitch Accent in Native Speakers of English & Mandarin Learners of English
Authors: Frazier Sonja
Published: April 2021

This research project was conducted as a pilot study to explore how pitch accent is used by NCES (Native Canadian English Speakers) and MLE (Mandarin Learners of English). Pitch accents are the prominent high or low tones, that are predominantly found on content words (N, V, Adv, Adj, etc.) in English. In order to compare how both speech communities use pitch accent in English, participants were given an EI (Elicited Imitation) Task. The EI involved participants hearing and then repeating a sentence. It is also reconstructive in nature meaning that the participants process the sentence, then reconstruct it with their own grammar, and finally reproduce it. The results showed that Mandarin speakers had more pitch accents than English speakers, adding pitch accents on function words (Art, Pro, Prep, etc.) as well. The results also demonstrated that Mandarin speakers had less creaky words (words said in a very low pitch, also known as laryngealization or vocal fry) than the English participants. Implications of this study concern ESL Education; such as should English pitch accent patterns and creak in English be taught to English language learners.
Professionalism and the Construction of Teacher Professional Identity
Authors: Gregory Ashlyn , Cathcart Emma , Bates Alex
Published: April 2021

Professionalism and the construction of teacher professional identity is a focus of our teacher education program and a pillar that guides the daily practices of educators (OCT, 2016). For teachers to be viewed as professionals within their classroom and community, they must understand the high standards of being a teacher and strive every day to meet and exceed those expectations (Hurst & Reading, 1999). The purpose of our collaborative research is to explore how teachers determine the fine line between professionalism and compassion in the classroom and in professional relationships. The findings suggest that professional relationships are constantly evolving and that boundaries are of utmost importance for teachers. Educators must follow professional standards while maintaining a balance between compassionate support and professional impartiality regarding student’s needs. The root of professionalism is effective multilateral communication between teachers, administration, parents, and students. A multi-faceted understanding of professionalism is essential for new teacher candidates to ensure their professional success and the effective learning of students in the classroom. These recommendations will help teacher candidates and new educators maintain professional relationships and evaluate their conduct within the educational community.
Underwater Surveys in Northern Menorca: Material Assemblages and Shipwrecks
Authors: Roberts Jacob
Published: April 2021

A plethora of archaeology currently resides unfound at the bottom of the Mediterranean Sea. Artifacts and material assemblages distributed throughout this sea serve as preserved time-capsules, representing a relatively underrepresented source of historical and archaeological analysis. This paper analyzes shipwrecks of the Balearic Sea along Menorca’s coastline to foreground the role that archaeology plays in reconstructing historical trade routes and ancient climatic during the late Roman period (4th – 7th CE). Implementation of this research occurred in the summer of 2016, using methodologies of underwater survey to investigate Menorcan shelf bathymetry and material evidence. Position fixing and visual search techniques formed the bulk of methodological fieldwork, principally completed underwater through scuba diving. Complementing this study and its framework is the use of materiality from the adjoining Roman sites of Sanisera and Port de Sanitja. Pairing material analysis of unearthed amphorae with geospatial study allows for a partial recreation of ancient maritime climates and sea conditions, as well as macroeconomic scenarios of Menorcan late antiquity. Such an investigation opens up untouched and unobserved histories.
The Marquis de Sade and the Power of Eroticism
Authors: Pourriahi Hasti
Published: April 2021

With increasing levels of consensus that sexuality is an important site of social diversity, we are gaining more insight into the detrimental social and psychological effects of sexual repression. Yet, sex continues to be a site shaped by taboo. Personal liberation seems to call for taboobreakers. With that, I ask whether there is anything liberating to learn from the life and work of one of the most notorious violators of sexual and other social mores. I consider the case of the Marquis de Sade (1740-1814). His writing and libertine philosophies were critical of the Catholic Church at a time when dissent was rising. But what made him so radical? Was he merely perceived as a threat by those wanting to protect their power? Or is there something more radically threatening and potentially liberating in his libertinism? What is it about the power of eroticism that makes it so threatening? Can this power be utilized as a tool for empowerment in the context of contemporary social justice struggles, or is it simply violence? I examine how de Sade’s work contributed to a radical counterargument against dominant sexually repressive mores. I conclude with critical remarks and provocative questions about the legacy of his work, which is no less relevant today than it has ever been
Examination of Anger Prevalence in NCAA Division I Student-Athletes
Authors: Madden Robert , Winkelmann Zachary , Weber Samantha , Moore Erin , Torres-McGehee Toni
Published: April 2021

Purpose: Anger associated with sports participation may affect inability to acutely process anger, may decrease performance and increase the likelihood of risk-taking behavior in collegiate athletes. Therefore, the purpose was to examine the prevalence of anger in collegiate student-athletes across sex, academic status, and sport type. Methods: A cross sectional study over a three-year period examined 759 NCAA Division I student-athletes at one institution (age=20±1 years; males: n=259; females: n=500) completed an optional pre-participation behavioral health screening questionnaire, personal demographic information and the Anger Index Self-Test. Results: Overall, 37.2% (n=282/759; males=127/259, 49.0%; females=155/500, 31.0%) of participants were at high-risk for anger. We identified a significant difference between the anger and sex [Χ2(2, N=759) =28.1, P≤0.01]. We also identified a significant difference between the anger and sport type [Χ2(8, N=759)=32.1, P≤0.01] with 55.2% (n=419/759) at moderate risk for anger despite sport type; with the highest percentages presenting high-risk for anger within power sports (n= 64/116, 55.2%) and ball sports (n=98/240, 40.8%). No significant differences were identified for anger risk and academic status (P=0.66). Conclusions: Female collegiate student-athletes demonstrated a higher prevalence of anger than male collegiate student-athletes, yet more males were high-risk. Most student-athletes displayed moderate-risk for anger across different sports. Anger across academic status was not significantly different implying that anger management and coping skills may need to be taught during their student-athlete tenure to mitigate the identified risk. A collegiate student-athlete’s inability to process anger may affect sports performance and have negative consequences on their personal and social life. A primary prevention mechanism exists to explore proper coping mechanisms for anger during sport before the onset of mental health conditions that could exacerbate the experience for the individual.
Indiana Secondary School Athletic Directors Perceptions of Athletic Training Services and Influences on Hiring Athletic Trainers
Authors: Greffly Thomas , Rivera Matthew , Eberman Lindsey
Published: April 2021

Purpose: The purpose of this investigation was to examine ADs perceptions on satisfaction of current care provided, factors influencing the hiring of ATs, and the roles and responsibilities of ATs. Methods: We used a mixed methods design with an online survey (Qualtrics®, Provo, UT), which we distributed to Indiana secondary school ADs (n = 410) with publicly available emails. The survey remained open for 5 weeks with reminder emails sent weekly. We used a panel (n=2) with experience in survey research and/or the secondary school setting. The survey included both quantitative (7 items) and qualitative (8 items) data. Participants were asked to share their perceptions on the roles/responsibilities of ATs as well as experiences with the challenges, barriers, and benefits of hiring ATs in open-ended questions. We used Kruskal-Wallis one-way ANOVAs to compare employment status, type of employer, and school size on satisfaction. We coded the open-ended responses using inductive coding with multi-analyst triangulation and auditing to establish trustworthiness. Results: We identified significant differences relative to employment status of the AT on satisfaction with overall care, whereby those with full-time athletic training services were more satisfied with care than those with per-diem, part-time services (p=0.010). When participants were asked about factors influencing the decision to provide services ADs reported liability, cost, and workload as major considerations. Conclusions: Consistent with previous research, financial challenges continue to play a role in the hiring of ATs in the secondary school setting, participants also identified the benefits of ATs in promoting safety, reducing liability, as well as the increased workload and cost. Access to qualified athletic healthcare continues to be a public health concern in America and all stakeholders should reconsider how to offer both a comprehensive athletics program and the healthcare needed to ensure safety in that participation.
Les justifications genrées de la transgression scolaire
Authors: Deyries Sophie Duteil
Published: April 2021

Cette étude s’inscrit dans le cadre d’une thèse en sciences de l’éducation soutenue en 2018 à l’Université de Montpellier, en France. De nombreuses études mettent en évidence le traitement différencié à l’œuvre dans l’espace scolaire lorsque les élèves filles ou les élèves garçons transgressent les règles. Mais nous sommes nous collectivement interrogés sur les arguments mis en avant pour justifier ces comportements, pour leur donner une explication? Enseignants comme élèves se confortent dans des justifications conformes aux représentations sociales. Les élèves garçons transgresseraient par immaturité, par envie de « faire l’intéressant » auprès des pairs ou encore par manque de contrôle de leurs émotions, comme la colère. En revanche, et pour une même transgression, les interviewés expliquent les écarts de comportements des élèves filles par des réactions de défense (et non d’attaque), des problématiques personnelles – auxquelles elles seraient soumises – et un manque cruel de modération dans leurs réactions. On juge les garçons responsables mais également soumis à leur nature, on considère les filles victimes des situations de transgressions en les dé-responsabilisant de leurs actes. À partir d’un échantillon de 500 élèves et 29 enseignants, de la maternelle au lycée, c’est à travers une enquête en partie qualitative (entretiens et observations) que je propose d’interroger et de penser la transgression scolaire au prisme d’un mécanisme qui s’entretient continuellement, et qui montre comment la transgression est un analyseur du genre scolaire.
Oxygenation by extracorphorus membrane (ECMO) installed during cardiorrespiratory stop in lung with acute respiratory anguish syndrome: a case report
Authors: Donnabella Camille , Garcia Guilherme , Sato Monica
Published: April 2021

Extracorporeal membrane oxygenation (ECMO) provides a better oxygen supply to patients with severe respiratory and cardiac diseases refractory to conventional therapy. ECMO installed during cardiorespiratory arrest (CPR) is called ECPR, which has been improved, presenting favorable results. The present article is an observational study, whose material was the medical record of a patient with a diagnosis of acute respiratory distress syndrome (ARDS) where ECMO was performed during a successful cardiorespiratory arrest. Clinical, laboratory and radiographic data were evaluated, which reflect and corroborate the pathophysiology of the disease and the structural alteration of the respiratory system. This paper aims to describe a clinical case of successful ECPR in a 2-year-old female patient with hospital admission for extensive pneumonia who progressed with ARDS and cardiac arrest refractory to conventional treatment.

Objective: To analyze the practices of general practitioners (GPs) in terms of recommendations on individual screening for prostate cancer (PCa). Methods: An anonymous cross-sectional survey using a pre-established questionnaire was conducted among 193 GPs in the city of Lubumbashi from May 1st to July 31st, 2020. The questionnaire included three parts: identity criteria of GPs, screening practice and the opinion of GPs on the recommendations. Results: The participation rate was 79%. Eighty-two-point nine percent of respondents said they offered screening for PCa; 42.5% of them said they offered this screening to all men within a certain age limit, ranging between 50 to 75 years in 38.8% of the cases. Only 12.5% of GPs provided complete prior information to their patients. Thirty-six-point three percent of GPs reported combining digital rectal examination with total PSA testing, but in the presence of an abnormality, 60.6% reported that they referred their patients directly to the urologist without ordering other additional investigations (first or second line). Finally, 32.7% of GPs found that the recommendations disseminated were appropriate for their practice. Conclusion: Individual screening for PCa is widely proposed; but there are differences between the practices reported by GPs and official recommendations of learned societies. Our study highlights the need to popularize the recommendations of learned societies to GPs.

The movement of currency exchange rate can be predicted in the next few days, this is used by economic actors to get profit. Artificial Neural Network with the backpropagation learning method is good enough to use for forecasting time series data, it's just that in its application this method was considered to have shortcomings such as a long training time to achieve convergence. The purpose of this research is to form a Multilayer Perceptron Artificial Neural Network model with the Particle Swarm Optimization (PSO) algorithm as a learning method in the case of currency exchange rate prediction. This research produced a model that can predict the movement of the Rupiah exchange rate against the US Dollar, while the model formed was the MLP-PSO model with an error rate of 5.6168 x 10-8, slightly better than the MLP-BP model with an error rate of 6.4683 x 10-8. These results indicated that the PSO algorithm can be used as a learning algorithm in the Multilayer Perceptron Artificial Neural Network.

Introduction Loss of teeth defines oral health status and chewing abilities. Caries and periodontal disease have been associated with systemic diseases, however they may contribute to cognitive impairment too. Mastication assessment appears to possess broad significance, and is needed to create background knowledge for chewing harmony. The aim of this study was to evaluate chewing performance and the characteristics of condylographic recordings, during mastication of Natural Food (NF) and a Standard Food Model (SFM), in subjects with different occlusal parameters. Methodology Twenty-three adult subjects’ mastication was assessed with a standardized recording protocol, when chewing onto SFM and NF in three different textures. Detailed occlusal characteristics, condylographic recording data and condylographic patterns during mastication were all analyzed and compared. Results Bilateral Crossbites, Missing Molars and Asymmetric Molar Class were related to higher disharmony and transversal displacement during chewing. Missing and unreplaced molars showed dysfunctional patterns and so did worn out occlusal surfaces. Molar Class alone did not prove to be a useful predictor in chewing test results. Conclusion Increasing evidence indicates that oral health has an impact on Individual and Public Health. It is important to understand that oral health and its functional status are to be maintained during one’s lifetime, and that preventive, therapeutic measures at all ages should have a common functional target to grant neurobiological health as well as nutritional goals of Mastication. Further studies are needed to better understand the relevance of additional parameters such as Occlusal Plane Inclination, Curve of Spee, and three-dimensional asymmetries.

Trichophyton(T.)mentagrophytesnow accounts for an overwhelming majority of clinical cases in India, a new “Indian genotype” (T. mentagrophytes ITS genotype VIII)having been isolated from skin samples obtained from cases across a wide geographical distribution in this country. The conventional diagnostic methods, like fungal culture, are, however, inadequate for diagnosing this agent. Thus, molecular methods of diagnosis are necessary for proper characterization of the causative agent. The shift in the predominant agent of dermatophytosis fromT. rubrumtoT. mentagrophytes, within a relatively short span of time, is without historic parallel. The apparent ease of transmission of a zoophilic fungus among human hosts can also be explained by means of mycological phenomena, like anthropization.

Physics-inspired Artificial Intelligence (AI) is at the forefront of methods development in molecular modeling and computational chemistry. In particular, interatomic potentials derived with Machine Learning algorithms such as Deep Neural Networks (DNNs), achieve the accuracy of high-fidelity quantum mechanical (QM) methods in areas traditionally dominated by empirical force fields and allow performing massive simulations. The applicability domain of DNN potentials is usually limited by the type of training data. As such, transferable models are aimed to be extensible in the description of chemical and conformational diversity of organic molecules. However, most DNN potentials, such as the AIMNet model we proposed previously, were parametrized for neutral molecules or closed-shell ions due to architectural limitations. In this work, we extend machine learning framework toward open-shell anions and cations. We introduce AIMNet-NSE (Neural Spin Equilibration) architecture, which being properly trained, could predict atomic and molecular properties for an arbitrary combination of molecular charge and spin multiplicity. This model explores a new dimension of transferability by adding the charge-spin space. The AIMNet-NSE model is capable of reproducing reference QM energies for cations, neutrals, and anions with errors of about 2-3 kcal/mol, compared to the reference QM simulations. The spin-charges have errors ~0.01 electrons for small organic molecules containing nine chemical elements {H, C, N, O, F, Si, P, S and Cl}. The AIMNet-NSE model allows to fully bypass QM calculations and derive the ionization potential, electron affinity, and conceptual Density Functional Theory quantities like electronegativity, hardness, and condensed Fukui functions with a speed up to 104 molecules per second on a single modern GPU. We show that these descriptors, along with learned atomic representations, could be used to model chemical reactivity through an example of regioselectivity in electrophilic aromatic substitution reactions.

within its genome. Bioinformatics strategies can facilitate comprehending this organism through

functional and structural interpretation assessments.This study aimed to allocate the structure and

function through an in-silico approach required for bacterial protein biosynthesis. This in-silico

viewpoint provides copious properties, including the physicochemical properties, subcellular location,

three-dimensional structure, protein-protein interactions, and functional elucidation of the protein

(WP_012256288.1). The STRING program is utilized for the explication of protein-protein

interactions. The in-silico investigation documented the protein's hydrophilic nature with

predominantly alpha (α) helices in its secondary structure.The tertiary-structure model of the protein

has been shown to exhibit reasonably high consistency based on various quality assessment

methods.The functional interpretation suggested that the protein can act as a translation initiation

factor, a protein required for translation and protein biosynthesis. Protein-protein interactions also

demonstrated high credence that the protein interconnected with 30S ribosomal subunit involved in

protein synthesis. This study is bioinformatically examined that the protein (WP_012256288.1) is

affiliated in protein biosynthesis as a translation initiation factor IF-3 of C. aurantiacus.
Mode-Selective Chemistry through Polaritonic Vibrational Strong Coupling

Recent experiments have demonstrated remarkable mode-selective reactivities by coupling molecular vibrations with vacuum fluctuations inside an optical cavity. The fundamental mechanism behind such effects, on the other hand, remains elusive. In this work, we theoretically demonstrate the basic principle of how cavity photon frequency can be tuned to achieve mode-selective reactivities. We find that the non-Markovian nature of the radiation mode leads to a cavity frequency-dependent dynamical caging effect of a reaction coordinate, resulting in a suppression of the rate constant. In the presence of multiple competitive reactions, it is possible to preferentially cage a reaction coordinate when the barrier frequencies for competing reaction paths are different. Our theoretical results illustrate the cavity-induced mode-selective chemistry through polaritonic vibrational-strong couplings, revealing the fundamental mechanism for changing chemical selectivities through cavity quantum electrodynamics.

Molecular networking of non-targeted tandem mass spectrometry data connects structurally related molecules based on similar fragmentation spectra. Here we report the Chemical Proportionality contextualization of molecular networks. ChemProp scores the changes of abundance between two connected nodes over sequential data series which can be displayed as a direction within the network to prioritize potential biological and chemical transformations or proportional changes of related compounds. We tested the ChemProp workflow on a ground truth data set of defined mixture and highlighted the utility of the tool to prioritize specific molecules within biological samples, including bacterial transformations of bile acids, human drug metabolism and bacterial natural products biosynthesis. The ChemProp workflow is freely available through the Global Natural Products Social Molecular Networking environment.
