Authors: Trindade Yasmin Rodrigues de Almeida , Figueira Luiz Eduardo
Published: April 2021

Este trabalho é uma descrição e análise das rotinas de trabalho dos profissionais envolvidos na preparação e execução das audiências de custódia na Central de Audiências de Custódia do Rio de Janeiro, situada na Favela do Arará, em Benfica, Zona Norte do Rio de Janeiro. Por meio do trabalho de campo e da observação participante, compilamos e interpretamos os dados etnográficos, produzidos entre 2018 e 2019, à luz dos estudos sobre cultura jurídica no Brasil. O objetivo foi compreender as motivações desses profissionais – a partir de suas vinculações institucionais e interesses pessoais –, as suas percepções e os efeitos que produzem nas audiências de custódia. Neste artigo, trabalhamos com as rotinas de produção documental e as defesas pública e privada em perspectiva comparada. Por fim, como as relações entre o crime, os documentos e o corpo do custodiado, apresentados juntos na audiência, compõem o repertório do juiz para a decisão que pode variar, ainda que se trate da mesma tipificação penal.
Os Modelões e a Mera Formalidade: Produção de Decisões e Sentenças em uma Vara Criminal da Baixada Fluminense do Rio de Janeiro
Authors: Garau Marilha Gabriela Reverendo
Published: April 2021

Neste artigo, descrevo de que forma são produzidas decisões e sentenças numa Vara Criminal da Baixada Fluminense do Rio de Janeiro. A interlocução que me permitiu observar as práticas e discursos dos atores que atuam no gabinete como parte do processo de tomada de decisões aconteceu entre março e outubro de 2018, durante visitas periódicas semanais à Comarca. A descrição densa dessas práticas, a partir da análise das rotinas internas do gabinete, aponta para a prevalência de modelos de decisões e sentenças que já foram tomadas antes dos fatos serem levados ao conhecimento da juíza titular da vara. Tal característica revela a prevalência de uma prática que classifico como procedimentalização que, por sua vez, está orientada pela preservação da presunção de culpa do réu ao longo do processo. Ao que parece, as etapas que se pretendem defensivas não representam uma oportunidade de defesa do réu senão um fim em si mesmas, portanto, são levadas a cabo por mera formalidade. Percebo nessa dinâmica uma rotina que separa os casos semelhantes dos casos excepcionais. O ritual das audiências também foi percebido como parte dessa procedimentalização que será inevitável nos casos semelhantes, mas que pode representar uma oportunidade de apresentar ao julgador um caso excepcional.
Entre Justaposições e Contraposições: Instrumentos Jurídicos, Discursos e Práticas em Torno da Administração de Homens Autores de Violência Doméstica Contra a Mulher
Authors: Lopes Paulo Victor Leite
Published: April 2021

Neste artigo, desenvolvido a partir de etnografia conduzida em uma instância administrativa destinada aos homens autores de violência doméstica e familiar contra a mulher na Região Metropolitana do Rio de Janeiro, demonstro como naquele espaço determinadas interpretações de práticas jurídicas e dos discursos relacionados a elas associam-se a elaborações sobre o Estado, o seu aparato legal e as suas formas de atuação. A partir da análise dos dispositivos jurídicos que administram aqueles sujeitos, e dos sentidos associados a eles durante os chamados “grupos reflexivos”, concluo que um dos seus efeitos é a produção de uma espécie de “suspensão” dos sujeitos, cujo horizonte e experiência aproximam-se formas de governo pelo medo.

Genetic variation associated with lower susceptibility to sea star wasting syndrome in the keystone species, Pisaster ochraceus
Authors: Burton Andrea , Gravem Sarah , Barreto Felipe
Published: April 2021

The keystone species, Pisaster ochraceus, suffered mass mortalities
along the northeast Pacific Ocean from Sea Star Wasting Syndrome (SSWS)
outbreaks in 2013-2016. Causation of SSWS is still debated, leading to
concerns as to whether outbreaks will continue to impact this species.
Considering the apparent link between ocean temperature and SSWS, the
future of this species and intertidal communities remains uncertain. We
surveyed populations of sea stars along the Oregon coast in 2016, two
years after the epidemic began. Cohabitation of asymptomatic and
symptomatic individuals allowed us to ask whether lower susceptibility
in asymptomatic individuals differed genetically. We performed
restriction site-associated DNA sequencing (2bRAD-seq) to genotype
thousands of single nucleotide polymorphism (SNP) loci. By comparing
allele frequencies between symptomatic and asymptomatic individuals, we
detected three loci that may be under selection. A multivariate analysis
showed a clear separation between groups based on disease status in two
of the three geographic regions, along with several regions across the
genome having small statistical contributions to this separation. A
draft annotation of protein-coding regions allowed us to identify 120
predicted genes that are linked to these markers and are putatively
associated with lower susceptibility. Our results suggest that some
variation in disease severity can be attributed to genetic variation.
However, differences in phenotype have a highly polygenic nature with no
single or few genomic regions having strong predictive effects. The
genes associated with these regions may form the basis for functional
studies aiming to understand disease progression in infected
individuals.
Hydrologic-land surface modelling of the Canadian sporadic-discontinuous permafrost: initialization and uncertainty propagation
Authors: Abdelhamed Mohamed , Elshamy Mohamed , Wheater Howard , Razavi Saman
Published: April 2021

Permafrost thaw has been observed in recent decades in the Northern
Hemisphere and is expected to accelerate with continued global warming.
Predicting the future of permafrost requires proper representation of
the interrelated surface/subsurface thermal and hydrologic regimes. Land
surface models (LSMs) are well suited for such predictions, as they
couple heat and water interactions across soil-vegetation-atmosphere
interfaces and can be applied over large scales. LSMs, however, are
challenged by the long-term thermal and hydraulic memories of permafrost
and the paucity of historical records to represent permafrost dynamics
under transient climate conditions. In this study, we address the
challenge of model initialization by characterizing the impact of
initial climate conditions and initial soil frozen and liquid water
contents on the simulation length required to reach equilibrium.
Further, we quantify how the uncertainty in model initialization
propagates to simulated permafrost dynamics. Modelling experiments are
conducted with the Modélisation Environmentale Communautaire – Surface
and Hydrology (MESH) framework and its embedded Canadian Land Surface
Scheme (CLASS). The study area is in the Liard River basin in the
Northwest Territories of Canada with sporadic and discontinuous regions.
Results show that uncertainty in model initialization controls various
attributes of simulated permafrost, especially the active layer
thickness, which could change by 0.5-1.5m depending on the initial
condition chosen. The least number of spin-up cycles is achieved with
near field capacity condition, but the number of cycles varies depending
on the spin-up year climate. We advise an extended spin-up of 200-1000
cycles to ensure proper model initialization under different climatic
conditions and initial soil moisture contents.

Authors: Popovic Jasmina , Popovic Mladjan , Djiporovic-Momcilovic Milanka , Prahin Ana , Dodevski Vladimir , Gavrilovic-Grmusa Ivana
Published: April 2021

Particles of beech wood were treated with hot water at the temperature of 150
oC, during 60 min, prior to the pelleting process. The applied hot water
pretreatment affected the chemical composition and heating value of
particles. Two groups of pellets, designated as PT 10 and PT 20, were
produced from treated beech particles, with the moisture content of
particles being 10.5 and 20.5 %, respectively. Pellets from nontreated beech
particles (PNT) served as controls to assess the hot water pretreatment
effects on the pellet properties. Both, the applied pretreatment, and the
particle moisture content, affected properties of the obtained pellets. The
heating value of PT 10 ad PT 20 pellets has increased for ~6 and 1 %,
respectively. The mineral (ash) content in treated pellets decreased for
about 24 % in comparison to that in PNT pellets. In addition, the bulk
(apparent) density of pellets has increased for 21 % (PT 10) and 10 % (PT
20), as a consequence of the hot water pretreatment of particles. The
specific density of PT 10 pellets was for 16 % higher, while the equilibrium
moisture content (after conditioning at RH 68 % and 20.1?C) was for about
32 % lower in comparison to the respective properties of PNT pellets.
Microstructure as an essential aspect of EN AW 7075 aluminum alloy quality influenced by electromagnetic field during continuous casting process
Authors: Pataric Aleksandra , Mihailovic Marija , Markovic Branislav , Sokic Miroslav , Radovanovic Andreja , Jordovic Branka
Published: April 2021

Microstructure assessment is crucial for the design and production of
high-quality alloys such as cast aluminum alloy ingots. Along with the
effect of a more homogeneous microstructure to result in much better
mechanical properties, better as-cast alloy quality indicates a higher
efficiency of the aluminum alloys production process. During the aluminum
alloy solidification process many microstructural defects can occur, which
deteriorate the mechanical properties and hence decrease the usability of
such an ingot. Application of the electromagnetic field during the vertical
continuous casting process significantly reduces occurrence of these
defects. In the present study, EN AW 7075 alloy samples were cast with and
without application of an electromagnetic field and examined regarding the
microstructure, electrical conductivity, and changes in the phase
composition. The obtained results clearly show that it is possible to
decrease or avoid casting defects by the electromagnetic field application
as verified by the microstructure characterization and quantification,
electrical conductivity tests and differential thermal analysis (DTA).
How Do Firms Use Cash Tax Savings? A Cross-Country Analysis
Authors: Green Danielle H. , Kerr Jon N.
Published: April 2021

We examine how firms utilize cash generated via tax avoidance. Understanding how firms use these cash flows is important given the considerable global attention firms' tax avoidance activities have received. Using an international sample, we find that firms are more likely to invest cash tax savings or use them to repurchase shares rather than distribute them in the form of dividends. We find that our results hold for an international sample of domestic-only firms, distinguishing our study from U.S.-only studies, which focus on constraints and distortions of multinational corporations in a worldwide tax system. When partitioning on country-level governance, we find that firms in weak governance countries are more likely to use tax savings to fund investment and pay dividends. Taken together, our results suggest cash tax avoidance is associated with important firm decisions, and these associations vary across countries.

Inhibition of SGLT2 Rescues Bone Marrow Cell Traffic for Vascular Repair: Role of Glucose Control and Ketogenesis
Authors: Albiero Mattia , Tedesco Serena , Amendolagine Francesco Ivan , D’Anna Marianna , Migliozzi Ludovica , Zuccolotto Gaia , Rosato Antonio , Cappellari Roberta , Avogaro Angelo , Fadini Gian Paolo
Published: April 2021

The mechanisms by which sodium–glucose cotransporter 2 inhibitors (SGLT2i) improve cardiovascular outcomes in people with diabetes are incompletely understood. Recent studies show that SGLT2i may increase the levels of circulating cells with vascular regenerative capacity, at least in part by lowering glycemia. In this study, we used mice with streptozotocin-induced diabetes treated with the SGLT2i dapagliflozin at a dose that reduced glucose levels by 20%. Dapagliflozin improved the diabetes-associated defect of hematopoietic stem cell mobilization after stimulation with granulocyte colony-stimulating factor. Dapagliflozin rescued the traffic of bone marrow (BM)–derived cells to injured carotid arteries and improved endothelial healing in diabetic mice. Defective homing of CD49d+ granulocytes was causally linked with impaired endothelial repair and was reversed by dapagliflozin. The effects of dapagliflozin were mimicked by a similar extent of glucose reduction achieved with insulin therapy and by a ketone drink that artificially elevated β-hydroxybutyrate. Inhibition of endothelial repair by resident cells using the CXCR4 antagonist AMD3100 did not abolish the vascular effect of dapagliflozin, indirectly supporting that endothelial healing by dapagliflozin was mediated by recruitment of circulating cells. In summary, we show that dapagliflozin improved the traffic of BM-derived hematopoietic cells to the site of vascular injury, providing a hitherto unappreciated mechanism of vascular protection.

Published: April 2021

Purpose:
To determine whether interrupting sitting with brief bouts of simple resistance
activities (SRAs) at different frequencies improves postprandial glucose,
insulin and triglycerides in adults with medication-controlled type 2 diabetes
(T2D).

Methods:
Participants [n=23, 10 females, Age: 62±8 y (mean±SD), BMI: 32.7 ±
3.5 kg.m-2] completed a three-armed randomized crossover
trial (6-14 day washout): sitting uninterrupted for 7 h (SIT); sitting with
3-minute SRAs (half-squats, calf
raises, gluteal contractions, and knee raises) every 30 minutes (SRA3); and, sitting with 6-minute SRAs every 60
minutes (SRA6). Net incremental areas under the curve (iAUCnet) for
glucose, insulin, and triglycerides were compared between conditions.

Results: Glucose and insulin 7 h iAUCnet were attenuated
significantly during SRA6 (glucose 17.0 mmol.h.L-1,
95% CI 12.5, 21.4; insulin 1229 pmol.h.L-1,
95% CI 982, 1538) when compared to SIT (glucose 21.4 mmol.h.L-1,
95% CI 16.9, 25.8; insulin 1411 pmol.h.L-1,
95% CI 1128, 1767; P < 0.05), and compared
to SRA3 ( for glucose only; 22.1 mmol.h.L-1,
95% CI 17.7, 26.6; P = 0.01) No significant differences in glucose or
insulin iAUCnet were observed comparing SRA3 and SIT. There was no
statistically significant effect of condition on triglyceride iAUCnet.

Conclusion:
In adults with medication-controlled T2D, interrupting prolonged sitting with 6-minute
SRAs every 60 minutes reduced postprandial glucose and insulin responses. Other
frequencies of interruptions and potential longer-term benefits require examination
to clarify clinical relevance.
Calcific aortic valve stenosis: potentials and complications of surgical treatment
Authors: Smirnova Elena A. , Terekhina Alena I. , Filonenko Sergey P. , Muranchik Elena N.
Published: April 2021

Aim. The study aim is to discuss different approaches to the selection of a method of surgical correction of pronounced aortic stenosis (AS). Indications, contraindications, advantages and probable complications of transcatheter aortic valve implantation (TAVI) are considered. A description of a clinical case is given, and probable causes of unfavorable outcomes are discussed.
AS is the most common valvular disease, and its frequency increases significantly with age. It is one of the leading indications for heart surgery. A peculiarity of the clinical presentation of AS is a long asymptomatic period that varies from patient to patient. With the appearance of the first clinical manifestations, the prognosis of the disease sharply worsens. For a long time, surgical replacement of the aortic valve remained the gold standard of treatment of patients with symptomatic AS. An increase in the number of elderly patients and those in old age with many comorbid diseases who have received cardiopulmonary bypass is linked with an increased risk of postoperative complications, which are became a determining factor for the development of alternative methods of surgical correction of aortic valve pathology.
Conclusion. At present, TAVI has considerable advantages over surgical replacement; is a method of choice for elderly and inoperable patients as well as patients at high, intermediate, and low risk from surgery; and requires a multidisciplinary approach.

Published: April 2021

This article contains a literature review of the results of experimental and clinical studies of the influence of physical exercise on the clinical course of bronchial asthma (BA) and presents the pathophysiological mechanisms of this influence. A high prevalence of sedentary lifestyle among patients with BA, its cause, and consequences are considered. Some studies have shown that patients with BA more rarely perform physical activity, and their physical exercises are less intensive and/or take shorter time. Effects of different variants of physical exercise on patients with BA are also discussed. Regular aerobic and mixed exercises of moderate intensity reliably lead to an improvement of the quality of life, reduction of exacerbations, use of inhalators on demand, nocturnal symptoms, and sleep; to a reduction of the hyperresponsiveness of the bronchi, eosinophil count in the sputum, levels of interleukin-6, and monocyte chemotactic factor-1; and to an increase in the level of interleukin-10. SOCS-JAK-STAT plays a role in the mechanism underlying the influence of aerobic exercises on inflammation, remodeling, and hyperresponsiveness of the airways by decreasing the expression of Th2 cytokines, chemokines, adhesion molecules, growth factors, NF-kB, and P2X7 receptors by the epithelium of the airways and by an increase in interleukin-10 level.
Conclusion. Data available in the literature are obtained on small cohorts of foreign patients. Clinical data devoted to the influence of aerobic exercises on control of BA and parameters of the respiratory functions are contradictory. Further investigations are required in this field.

Authors: Saryeva Olga P. , Vahromeev Aleksej P. , Parejshvili Violetta V.
Published: April 2021

Aim. This study aimed to identify peculiarities of the course of pregnancy, delivery, and morphology of the placenta in women with undifferentiated connective tissue dysplasia (UCTD).
Materials and Methods. The main group included 60 pregnant women with UCTD, and the control group was composed of 30 somatically healthy women with physiological course of pregnancy. All patients were examined as regards the use of general clinical and laboratory methods. Moreover, 65 placentas were subjected to complex morphological examinations, including organometry, macro- and microscopic examinations, and immunohistochemistry.
Results. Pregnancy and delivery in women with UCTD encounter various complications, such as threat of premature birth and miscarriage, pre-eclampsia, prenatal amenorrhea, and placental insufficiency manifested as fetal growth restriction syndrome and confirmed in the course of morphological examination. The structural basis of chronic placental insufficiency is associated various pathologies of the umbilical cord and disorders in maturation of the villous chorion with the underlying weak adaptive and compensatory processes. Connective tissue dysplasia in fetal membranes is manifested as disorders in histo- and cytoarchitectonics and in increased expression of matrix metalloproteinase-9 by amniocytes and cytotrophoblast cells.
Conclusion. UCTD produces unfavorable effect on the course of pregnancy and delivery. The results of the clinical and morphological examinations demonstrate the multiorgan characteristics of injuries in the mother-placenta-fetus system, which necessitates further studies for the determination of complex prophylactic measures.
Assessment of Microbiological Quality and Safety during the Processing of Traditional Beers made from Sorghum in the “Mandara” Mountains of the Far-North Region of Cameroon
Authors: Bayoï James Ronald , Etoa François-Xavier
Published: April 2021

Indigenous beers are very popular and widely consumed by people from northern Cameroon because of its low cost. Despite their appeal, microbial quality of these beverages remains a serious call for concern. This work was aimed to investigate microbial changes and hazards of contamination during the processing of two special sorghum beers brewed in northern Cameroon. Producers were observed during the production and samples were collected at different stages for analysis of microbiological parameters such as total count, fungi, spore-forming bacteria, Coliforms and E. coli using referenced methods. Total count ranged from 13.5 x 103 to 195 x 103 CFU/mL and 0.16 x 103 to 660 x 103 CFU/mL; fungi from 0.26 x 103 to 22 x 103 CFU/mL and 0.22 x 103 to 85 x 103 CFU/mL; E. coli from 0.69 x 102 to 13.6 x 102 CFU/mL and 0.65 x 102 to 3.8 x 102 CFU/mL during the production of the red “té” and white “mepdli” beers, respectively. Spore-forming bacteria and Coliforms (total and fecal) were detected in all the collected samples. Bacterial spores were also enumerated in red (38 x 103 CFU/g) and white (62.5 x 103 CFU/g) sorghum grains used as the main raw materials for the production of “té” and “mpedli” beers. The results suggest that the processing of both turbid beers using the traditional method are exposed to microbial contamination. Increase of microbial loads after soaking, adding of the supernatant (red beer only) and malted flour (white beer only) after the heating step means that control measures are needed to prevent contamination after these sensitive stages. Proper handling of raw materials, adequate implementation of heating and fermentation were found as effective critical control points. Training of producers on the hazards analysis and good manufacturing and hygiene practices have been suggested as strategies to improve the safety of indigenous beers.

The main purpose of the study predetermines the main issue of the article: to show the importance of formation of a culture of working with information among students during distance learning, which means the ability to evaluate, perceive information, prevent manipulation, distinguish truth from falsehood. The main task is to assess the existing and desired level of this competence, to develop an organizational model of its formation which consists of the following components: goals and objectives, pedagogical conditions and evaluation criteria. The model was implemented simultaneously at the Drahomanov National Pedagogical University and National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute” by teachers of humanities in experimental and control groups (16 people) in three stages: ascertaining, formative and final. A questionnaire and a self-assessment map of the formation of the culture of working with information were developed for the ascertaining stage; purposeful work with students was conducted (special tasks, discussion conversations, discussions) at the formative stage the results before and after the experiment were compared at the final stage in particular. Positive dynamics in the experimental group was noted, the average rate of formation increased. The proposed evaluation criteria – motivational, cognitive and activity ones have demonstrated practical value. It is advisable to recommend their use at other faculties. It is concluded that the organizational model is effective. The prospect of the study is the scientific substantiation of the implementation of the model among a wider range of students and the development of a distance specialized course.
Public Health Perspective on Magnesium
Authors: Šoher Lidija , Banjari Ines
Published: April 2021

Magnesium is a cofactor in more
than 300 enzymes, it plays a vital role in energy metabolism, homeostasis of
electrolites, and bone metabolism, and regulates a number of fundamental functions
such as muscle contraction, neuromuscular conduction, glycemic control, and
blood pressure. Magnesium deficiency has been associated with a wide range of
diseases, from cardiovascular diseases, hypertension, diabetes, to anxiety and
other mental disorders, migraine and osteoporosis, and especially worrying is
subclinical form which is estimated to affect up to 30% of the population.
Recommended dietary intake of magnesium is 300 mg and 350 mg per day for adult
males and females, respectively. While highly abundant in a variety of foods,
especially green leafy vegetables, nuts and seeds, water is the main
contributor to magnesium daily intake. Water has been the focus of a number of
public health interventions aiming to improve magnesium status of populations, especially
in Israel and Australia. Supplements are becoming a more important contributor
to the total magnesium intake, especially among physically active individuals.
Public awareness of the health benefits gained from physical activity is
improving, and more individuals decide to engage in (recreational) physical
activity. Even though physical activity increases the risk of magnesium
deficiency, misuse of supplements due to lack of knowledge and misinformation
shared on social networks can have a detrimental effect on individual’s health and physical performance.
Povezanost igračke pozicije na incidenciju ozljeda kod

Published: April 2021

Budući da je košarka sport s puno brzih promjena,
doskoka i okreta, ozljede su njezin sastavni dio te treba staviti poseban
naglasak na njihovu prevenciju. Uzroci ozljeda su različiti, mogu biti unutrašnji (genski, anatomski, biomehanički, hormonalni) i vanjski (podloga,
obuća), a njihov mehanizam nastanka može biti bez kontakta ili uz kontakt
s igračicom ili podlogom. Kako bi se ozljede
smanjile, važnu ulogu ima fizioterapeut koji bi,
kao sastavni dio svake ekipe, trebao provoditi edukaciju, prevenciju i
rehabilitaciju ako se ozljeda već dogodila. Prema dostupnoj literaturi, prevencija bi se trebala
uklopiti u program treninga i odvijati kroz minimalno tri treninga tjedno.

Cilj ovog rada bio je utvrditi
povezanost učestalosti ozljeda s obzirom na igračku poziciju u sezoni 2016./2017. Za
potrebe istraživanja napravljen je upitnik s
devet pitanja na koja je odgovorilo 90 košarkašica iz 12 prvoligaških klubova. Nije pronađena statistički značajna razlika između ozljeda gležnja, koljena i Ahilove tetive s obzirom
na igračku poziciju.
Promjene u nekim aspektima mentalnog

Published: April 2021

S obzirom na rizike mentalnoga
zdravlja, adolescencija pripada u kritična životna razdoblja, a osim čimbenika iz obiteljskog konteksta,
za mentalno zdravlje od velike su važnosti i oni povezani sa školskim zahtjevima. U ovome radu
analizirani su podaci prikupljani od 141 polaznika zdravstvenih programa
tijekom četiri godine njihova srednjoškolskog obrazovanja. Prikupljani su
podaci o učestalosti negativnih automatskih
misli povezanih sa strahom od neuspjeha i ohrabrujućih automatskih misli za vrijeme učenja u ispitnim razdobljima pri
kraju nastavne godine. Svrha istraživanja bila je provjeriti smjer i doprinos pozitivnih i
negativnih automatskih misli u predviđanju dugoročnih emocionalnih ishoda, odnosno razine emocionalne
uznemirenosti na kraju srednje škole. Osim deskriptivne analize, u
obradi rezultata primijenjena je multipla regresijska analiza. Ovisno o godini
obrazovanja, oko 16 % sudionika za vrijeme učenja ima iznadprosječno učestale negativne automatskih misli,
13 do 18 % pozitivne automatske misli, dok 16 do 18 % sudionika ima iznadprosječnu razinu opće emocionalne uznemirenosti.
Rezultati su pokazali kako u ispitnim razdobljima pri kraju nastavne godine 15
% sudionika ima iznadprosječno povišenu razinu emocionalne
uznemirenosti kroz više godina, pa i na završetku srednje škole. Negativne automatske misli povezane
sa strahom od neuspjeha za vrijeme učenja na kraju drugog i trećeg razreda dobro predviđaju razinu emocionalne
uznemirenosti na kraju srednje škole, što upućuje na važnost negativnih kognitivnih
procjena za dugoročne nepovoljne emocionalne ishode. Prediktivnost
pozitivnih misli u predviđanju dugoročnih emocionalnih ishoda nije potvrđena. Rezultati se komentiraju u
kontekstu Lazarusove teorije stresa i suočavanja te Beckova kognitivnog modela disfunkcionalnog i
neadaptivnog ponašanja.

Authors: Martínez-Cabrera Francisco Ignacio , Martín-Barrero Alberto
Published: April 2021

Los objetivos del presente trabajo fueron valorar i) la carga semanal y ii) la carga del partido en jugadores de fútbol diferenciando entre sus posiciones de juego usando la percepción subjetiva del esfuerzo (RPE). Fueron analizados un total de 18 jugadores de fútbol profesional la Liga 2 de Rumania (segunda división). Para la valoración de la carga semanal, se emplearon ciclos de trabajo con 6 días entre cada partido oficial donde fueron tomados registros de RPE6-20 y duración total del entrenamiento y partido para conocer los datos de carga globales en cada uno de ellos. Los resultados mostraron como los defensas centrales (DC) y delanteros (DEL) reportaron una mayor exigencia física que el resto de sus compañeros tanto en la carga total semanal como en partido. En vista a los resultados, podemos concluir que la RPE6-20 es un método de control de carga permite diferenciar entre las exigencias para las diferentes posiciones de juego, lo cual resulta de gran ayuda para entrenadores y preparadores físicos como herramienta de monitorización debido a su validez, fiabilidad, facilidad y bajo coste.
Gender and Development: Where are the Men?
Authors: Mason Corinne
Published: April 2021

This presentation will focus on men, masculinities and the HIV/AIDS pandemic in Southern Africa. As the interest in gender and development in Africa increases among experts in the development field, men have been increasingly left out of the discourse. Given the severity of gender inequality in Sub-Saharan Africa, focus on women is necessary. However, due to the prevalence of issues such as violence and HIV/AIDS prevalence among men, masculinity as a social construct must be given appropriate attention. In 2000, The United Nation Joint Programme on HIV/AIDS launched a World AIDS Day campaign called “AIDS: Men Make a Difference”. A UNAIDS March 2000 report acknowledged the importance of working with men to halt the HIV/AIDS pandemic due to “cultural beliefs and expectations [which] heighten men’s vulnerability” to HIV/AIDS. Similarly, scholars have recently taken interest in the intersection between masculinity and HIV/AIDS. This presentation will provide an overview of the exclusion of men’s issues in development and the reasons why we need to start paying attention to masculinity as a gendered construct.
A Nonlinear System Modelling Technique Applied to a Microelectronic Circuit
Authors: O'Connor Michael
Published: April 2021

Parallel Cascade Identification (PCI) is a nonlinear system modelling method developed by Dr. Michael Korenberg of the Queen’s Electrical and Computer Engineering department. This method models dynamic systems with possibly high order nonlinearities and lengthy memory, given only input/output data for the system. The industry-standard Berkeley BSIM3 model for transistors involves 187 different parameters and hence is complex to execute. Dr. Korenberg’s method offers the possibility of making a simpler model of a given circuit, so that its responses to novel inputs can be more quickly computed (possibly at some cost in fidelity). In my presentation, I intend to present the results of applying PCI to a simulated amplifier circuit, a topic that has been treated only cursorily in the literature.
A Circle of Women: Creating Community for Healing at Four Directions Aboriginal Student Centre
Authors: Wesley Dana , Heslop Erin
Published: April 2021

Within the Queen’s University community there are limited culturally appropriate activities for Aboriginal students. Traditionally and currently it is not common practice for an Aboriginal person to go to a stranger for guidance for personal issues. It is more common to seek guidance from a family member, community member or an elder. Aboriginal women in communities across Canada were historically valued as leaders and respected in their various roles within those societies. After colonization Aboriginal peoples were forced to adopt European patriarchal values. Consequently women were no longer allowed to hold leadership positions within their communities and the roles that they did play were perceived as less valuable. In addition to this ideological shift, the spiritual connection that women previously held with each other was disconnected through various processes. The sixties scoop and residential schools were processes that had negatively affected these relationships within Aboriginal societies. The Women’s Circle strives to bridge the disconnect that occurred and utilize time spent together during traditional activities to provide a safe place for this healing to begin. The Women’s Circle will also support Queen’s University’s mandate of engaging diversity and encouraging the Non-Aboriginal community to learn more regarding Aboriginal cultures, as well as the mandate of Four Directions Aboriginal Student Centre, specifically to foster the emotional, mental, physical and spiritual well-being of the Aboriginal Students at Queen’s University.
3. Learning Modules in a Support Group Context for Caregivers of Individuals with Alzheimer’s Disease and Related Dementias
Authors: Nurdin Wafa , Wane Aicha
Published: April 2021

The majority of community dwelling individuals with dementia have informal caregivers. With the risk of developing care related stress, it is important for community agencies, like the Alzheimer Society of Kingston (ASK), to provide support, resources, and information. The goal of this intervention was that caregivers of individuals with Alzheimer’s disease and related dementias (ADRD) would improve physical, social, and mental well-being. A search of the literature, as well as surveys of support group facilitators, forty caregivers, and consultation with ASK helped determine information relevant to the caregivers. The purpose of this project was to develop learning modules on: a) using a problem-based strategy to assist with daily activities of the person they are caring for; b) self-care strategies; c) positive coping strategies; d) assertive communication skills, and e) home environment safety to be delivered during caregiver support groups. The module on a problem-based strategy to assist with daily activities was pilot tested, utilizing five caregivers. It was found that the learning module was approximately 30 minutes over the stated timeframe and the case study component of the module was ineffective. Recommendations include implementing the module as two parts. Furthermore, additional research is needed on the impact of the modules on caregiver stress and burden.
8. The Effect of Bythotrephes Longimanus on the Size Structure of Zooplankton Communities in the Muskoka Region, Ontario
Authors: Pokorny Johanna
Published: April 2021

Invasive species are considered the greatest threat to aquatic ecosystem biodiversity. Bythotrephes longimanus, an exotic zooplankton species introduced to North America in the 1980s, is threatening the structure of indigenous aquatic ecosystems as it continues to invade inland Ontario lakes. As a predacious zooplankton species, B. longimanus has been shown to decrease zooplankton abundance, species richness and shift zooplankton community size structure in invaded lakes. However, much of the previous research concerning the predatory effects of B. longimanus has been on surveys of a small number of lakes or has been in controlled mesocosm or lab-based experiments. This study examines the effects of B. longimanus on the zooplankton community using size-structure characterizations (grouping individuals from the community based on size) as community measures for 311 lakes in the Muskoka Region, a highly invaded watershed in Southern Ontario. More specifically, the study explores the size-spectra of invaded versus uninvaded lakes, with reference to an array of environmental lake characteristics (water chemistry, lake morphometry,etc.), and the relevance of B. longimanus activity on the regional scale. By using such a large-scale survey we will be able to appreciate regional-scale effects, as well as encompass the multiple and more indirect trophic interactions that B. longimanus is likely having with the entire aquatic community.

On the Rationality of Choice
Authors: Simmons Thomas
Published: April 2021

This presentation aims to explore the ubiquity of rationality in how people make choices. Historically, rationality has been conceived of as a scheme of certain values and beliefs, most often those that are compatible with a 'scientific way of thinking'. Subsequently, those who hold a different set of beliefs and  values are deemed 'irrational' or considered irreconcilably dissimilar from those who are 'rational.' What typical follows for the 'irrational' are unfavorable labels such as 'dogmatic', 'primitive', or even 'insane'. This presentation rejects these common views and offers an alternate model of rationality that depicts rationality as a template rather than a scheme of values. Rather than emphasize certain values as 'rational', this model emphasizes the role of value itself as the cornerstone of rationality. An advantage of this model is that the both the commonly considered 'rational' and 'irrational' are seen to be employing the same underlying structure in making choices; the divergence is in the values themselves and not the way of  thinking. What underlies these arguments is an aim to show that human beings are more alike than  different, no matter what kind of choices they make
Parts of Speech in Kinyarwanda
Authors:  Crandall Vanessa
Published: April 2021

Traditional grammar holds that parts of speech have broad semantic definitions: verbs are actions, nouns are entities, adjectives are states of being, and prepositions denote locations (Baker, 2003). This view is problematic, however, given that semantic concepts are lexicalized differently across languages. For example, through my field work with a native speaker of Kinyarwanda (Bantu family, spoken in  Central Africa), I have found that in this language, states can be lexicalized as adjectives, nouns, or verbs: (1) umugabo ni munini “The man is big” ADJECTIVE MAN IS LARGE (2) imbwa n’ umweru  “The dog is white” NOUN DOG IS WHITE (3) imbwa yera “The dog is white” VERB  DOG BE.WHITE The state of “being big” appears as an adjective, while the state of “being white” can be both a noun (2) and  a verb (3). The difference in category is appears to be motivated by the relative permanence of the state in  question. A changing (or changeable) state is encoded as a verb (3). To reflect a permanent/unchanging  state, an adjective or noun is used (1­2). Because the inventory of adjectives in Kinyarwanda is extremely  limited, many “adjectival” permanent states are encoded as nouns. This alternation demonstrates the central role of Aspect (defined as a linguistic function that “characterizes the relationship of a predicate to  the time interval over which it occurs” (Chung and Timberlake 1985:213)) in the lexicalization process. Aspect in Kinyarwanda takes the form of a verbal suffix, thereby necessitating the use of a verb when the state undergoes some sort of change. This phenomenon provides evidence that parts of speech are defined  at least in part by a language’s syntactic requirements above and beyond broader semantic generalizations.
Reflecting on the Advantages of Longitudinal Integrated Clerkships and COVID-19
Authors: Geiger Kyle , Bowman Jamie , DeWitt Dawn
Published: April 2021

The emergence of Coronavirus Disease 2019 (COVID-19) has dramatically changed the landscape of medical education. The global pandemic highlighted advantages of specific curricular frameworks.  Longitudinal, integrated approaches may avoid some of the educational consequences seen in traditional models. This viewpoint highlights the advantages of a longitudinal integrated clerkship during the COVID-19 outbreak. These advantages include a relatively even exposure to multiple specialties, discipline specific assessment information despite an early truncation of clinical activity, and a seamless transition to ongoing integrated online learning, as a single integrated virtual clerkship model for an entire class. Notably, the longitudinal integrated clerkship avoided consequences seen in traditional clerkships such as missing entire rotations positioned in March-June 2020 and therefore, clerkship grades. The longitudinal clerkship allowed for students to receive discipline specific grades in all core specialties based on assessment of individual skills (direct observation and assessment of skills such as physical exam and history) versus discipline specific knowledge (subject exams). In addition, there are advantages of pre-existing relationships with preceptors and patients that could facilitate engagement in ongoing contact during virtual clerkships and opportunistic clinical experiences when it is safe for students to re-engage in clinical activities.
