Indignação e brio: o discurso sobre a improdutividade do trabalhador brasileiro na Folha de S. Paulo
Authors: Feitosa Erike Luiz Vieira , Fanini Angela Maria Rubel 
Published: December 2018

Este artigo consiste em uma análise dialógica do discurso (ADD) que se volta para a construção discursiva sobre a improdutividade do trabalhador brasileiro presente em editorial publicado pela Folha de S. Paulo no mês de abril de 2014. O texto “Brasil improdutivo” recupera enunciações da revista britânica The Economist – que, por sua vez, constrói discursivamente os brasileiros como “gloriosamente improdutivos”. Obliterando vozes dissonantes, o jornal defende as premissas macroeconômicas da ideologia neoliberal e se contrapõe a medidas heterodoxas (keynesianas) que até então eram sustentadas pelos governos petistas. Posicionando-se a favor do capital, a publicação brasileira não apenas assume, mas intensifica a crítica estrangeira, reforçando a utilização do estereótipo cultural, de longa duração, que remete à imagem do brasileiro ocioso. No que diz respeito às noções de produtividade e trabalho, a análise identifica uma compreensão ideologicamente orientada para a lógica da acumulação de riquezas para poucos à custa da exploração de muitos. Quando se diz, então, que o trabalhador brasileiro ou que o Brasil é improdutivo, faz-se alusão à ideia de que ambos (país e trabalhador) deveriam produzir mais, gerar mais lucro. Tal denúncia é importante, haja vista que esses enunciados não se restringem às páginas opinativas dos jornais, mas permanecem em circulação, influenciando ideologias cristalizadas e também práticas do cotidiano, interferindo na constituição de uma consciência de si dos brasileiros, bem como na imagem que os outros (o mundo) têm deles (de nós). Palavras-chave: Neoliberalismo e keynesianismo. Trabalhador brasileiro. Trabalhador improdutivo. Análise dialógica de discursos jornalísticos.

Published: December 2018

RESUMO:Objetiva-se analisar os processos de implantação das primeiras instituições de ensino na cidade de Fátima do Sul, sul de Mato Grosso, com o intuito de compreender o papel da Igreja Católica, mais especificamente dos padres palotinos, no surgimento e funcionamento da escola paroquial primária “Vicente Pallotti” e do Instituto “D. Pedro II”, criadas em 1957 e 1966, respectivamente. O recorte final delimita-se em 1971, por compreender que a Lei 5.692/1971 apresenta novas configurações para o ensino. As principais fontes coletadas e analisadas foram: entrevistas narrativas, livro Tombo da Igreja Matriz e fotografias. Tendo entre os referenciais teóricos Magalhães (2004), Buffa (2007) e Sanfelice (2007) a análise foi apresentada em duas partes: 1. Principais acontecimentos sobre a criação do município de Fátima do Sul até a implantação das primeiras instituições. 2. Surgimento e funcionamento da escola primária paroquial “Vicente Pallotti” e do Instituto “D. Pedro II”. Conclui-se que sob influência dos movimentos da Igreja Católica na década de 1950, em prol da educação popular, o movimento social palotino construiu, em Fátima do Sul, as primeiras instituições educativas, de caráter confessional, representando “progresso” e “civilização” para o povo da cidade. De tal maneira que na década de 1960, a cidade era considerada avançada por contar, além do ensino primário, com o ensino secundário e cursos técnicos.
Low-velocity Gunshot Injuries to the Femur: What Is the Utility of Stabilizing Incomplete Fractures?
Authors: Nguyen Mai P. , Prayson Nicholas , Vallier Heather A. 
Published: December 2018

Introduction:
Extremity involvement is common among nonfatal gunshot injuries. Most of these injuries are low energy in nature and may be associated with fractures. Although displaced fractures of lower extremity long bones are often treated surgically, the purpose of this study was to review our experience in managing incomplete femur fractures caused by gunshot penetration and to develop treatment recommendations.

Methods:
We retrospectively reviewed clinical and radiographic data for 46 consecutive patients with incomplete femur fractures secondary to low-energy gunshot wounds. Fracture patterns included OTA/AO 31 (n = 7), 32 (n = 20), and 33 (n = 19). All fractures were nondisplaced and extra-articular. Type of treatment, clinical and radiographic healing, and related complications were recorded.

Results:
Thirty-two patients (70%) were managed nonsurgically with progressive weight bearing from toe touch to full weight bearing by 6 weeks of follow-up, whereas 14 patients (30%) underwent prophylactic fixation of the femur. No differences in treatment were seen based on age, body mass index, fracture pattern, or the presence of other fractures or systemic injuries. Two of the 32 patients (6.2%) treated nonsurgically for femoral shaft fractures fell subacutely after the original injury and displaced their fractures. Both underwent reduction and fixation. All other fractures maintained alignment until union. No infections or nonunions were seen. Among patients who underwent prophylactic fixation, two underwent removal of prominent implants after union.

Discussion:
Only 6% of incomplete femur fractures treated at our hospital required later surgery for fracture displacement. Although incomplete fractures occur infrequently, nonsurgical management with limited weight bearing seems to be successful and cost-effective for most patients. We propose initial nonsurgical management of nondisplaced femoral fractures secondary to cortical penetration from low-energy gunshot wounds.

Published: December 2018

Objective: Invasive candidiasis is associated with increased
morbidity and mortality in critically ill patients. Current study was undertaken
to study the colonization trend in critically ill patients admitted to a
medical /surgical ICU of a tertiary care teaching hospital.

Methodology: Data for the current study has been derived from a
larger database generated for external validation of risk prediction scores for
invasive candidiasis conducted in a 12 bedded medical/surgical ICU of a
tertiary care hospital of North India. Non neutropenic adult patients with
&gt;48 hours of ICU stay were included in the study. Colonization surveillance
samples were collected from oral cavity, endotracheal aspirates, axilla,
perineum and urine at the time of admission and then on 3rd, 7th,
14th and 21st day of ICU stay. Blood culture samples were
taken at admission and then as per physician’s discretion.

Results:
Total 200 patients were enrolled from July 2013 to November 2014. Ninety five
percent patients were colonized with Candida
either at admission or during their stay in ICU. The most common species
responsible for colonization was Candida
glabrata (27%) followed by C.
tropicalis (20.5%) and C. auris
(18%). Seventeen patients developed Candida
blood stream infection. C. tropicalis
was the most common species causing candidemia. C.auris was most frequent
colonizer of axilla (54.2%), while rectal swabs had high growth of C. glabrata (44.9%).

Conclusion: Our study population had high rate of Candida colonization. C. glabrata was the most common
colonizer followed by C. tropicalis. &nbsp;J

Published: December 2018

The objective of this paper was to calibrate and validate the CERES-Rice model in relation to the productivity estimate for the cultivar IRGA 424 in Rio Grande do Sul, using only information found in the literature. CERES-Rice is a model that simulates the development and productivity of a cultivar. To achieve this goal, it is necessary to obtain the genetic coefficients of the cultivar through the calibration process. The genetic coefficients describe the behavior of the plant in the soil-plant-atmosphere system. The GENCALC module present in the DSSAT was used for the calibration. After the calibration process with 30% of the assembled experiments, the validation was performed in the others. The results for productivity were considered acceptable, since most of the values were below 15%, only one of the results showed an error of 16,88%. Note that the model did not consider neither phenological stages nor fertilization or water issues in the calibration and validation process.

Published: December 2018

Nitrogen dioxide (NO2) is a gas emitted from anthropogenic sources directly into the atmosphere, with the most relevant being automotive vehicles. In this work were used the softwares Erdas Imagine, GRADS and R with data obtained from the NASA Geovanni platform (available at http://giovanni.gsfc.nasa.gov/giovanni/) from the Ozone Monitoring Instrument (OMI) sensor located on the satellite AURA. In the data series, averages, minimum and maximum were used to observe and identify the areas with the highest concentration of NO2 in the Northeast region and the behavior of the pollutant on the same region. Among the maximum values identified in each of the months, nine occurred in Bahia including the maximum value of the whole series in July in the region near Roda Velha in Bahia and has a value of 4.88E+15 1/cm2, the state with the lowest occurrence of high concentration values is Rio Grande do Norte, but the lowest mean (2.06E+15 1/cm2) and the lowest value (1.75E+15 1/cm2) occur in the region near the city of São Luís (Maranhão) at 2.06E+15 1/cm2.

Student Learners and Preferred Agents in Mental Health-Seeking: Assessing Higher Educational Services in a Pilot Study
Authors: CRAMER KENNETH , SCHUURMAN EMILY , ROPAT JORDYNNE 
Published: December 2018

ABSTRACT
The prevalence of mental health problems among student learners has increased in recent decades. University and college expectations, plus the requirement for effective time management (among other things), may significantly augment this problem. School assessment practices and learning demands may give rise to anxiety and depression within the student body, ultimately affecting both their psychological and academic outcomes. We considered the agencies that students typically approached in various daily situations (e.g., where do students turn with issues related to time management or personal adjustment and anxiety – Google, parents, best friends, professors, on-campus counseling centers). A sample of 103 students from the University of Windsor in Southwestern Ontario Canada indicated which of 15 agencies they would consult, should they encounter each of 50 scenarios related to broader categories (14 in total) such as death, school, time constraints, relationship, sexual harassment, etc. The non-use of Google and the under-utilization of the peer support and student counseling centers are discussed, as are the implications for university and college administrations' consideration of student mental health issues.
Distributed Adaptive Multi‐Lane Fusion Control for 2‐D Plane Vehicle Platoon With Distance Constraints and Angle Sensor Faults
Authors: Lin Manfei , Liu Chenglin , Cao Kecai 
Published: November 2024

ABSTRACTThis article investigates the distributed adaptive multi‐lane fusion control for two‐dimensional (2‐D) plane vehicle platoons with variable distance constraints, input hysteresis, and angle sensor faults. Variable distance constraints occur within a limited time interval (VDCOLT), which limits vehicle spacing within a variable range during preset time intervals while keeping the vehicle spacing unconstrained at other times. Combined with a transformed error function, a new shifting function is introduced to convert the constrained spacing error variables into the unconstrained variables while keeping the unconstrained variable unchanged. Designing the position controller ensures that the distance satisfies VDCOLT and reduces the adverse effects caused by unknown signs of input hysteresis by using a Nussbaum function. Moreover, a new angle controller based on the hyperbolic tangent function is designed to solve the problem of angle sensor faults. Furthermore, the stability of the vehicle platoon is achieved through the backstepping control and sliding‐mode control methods. Finally, a numerical simulation is provided to verify the proposed techniques.
Multifunctional Biocomposite Materials from Chlorella vulgaris Microalgae

Published: November 2024

AbstractExtrusion 3D‐printing of biopolymers and natural fiber‐based biocomposites enables the fabrication of complex structures, ranging from implants' scaffolds to eco‐friendly structural materials. However, conventional polymer extrusion requires high energy consumption to reduce viscosity, and natural fiber reinforcement often requires harsh chemical treatments to improve adhesion. We address these challenges by introducing a sustainable framework to fabricate natural biocomposites using Chlorella vulgaris microalgae as the matrix. Through bioink optimization and process refinement, we produced lightweight, multifunctional materials with hierarchical architectures. Infrared spectroscopy analysis reveals that hydrogen bonding plays a critical role in the binding and reinforcement of Chlorella cells by hydroxyethyl cellulose (HEC). As water content decreases, the hydrogen bonding network evolves from water‐mediated interactions to direct hydrogen bonds between HEC and Chlorella, enhancing the mechanical properties. A controlled dehydration process maintains continuous microalgae morphology, preventing cracking. The resulting biocomposites exhibit a bending stiffness of 1.6 GPa and isotropic heat transfer and thermal conductivity of 0.10 W/mK at room temperature, demonstrating effective thermal insulation. These characteristics make Chlorella biocomposites promising candidates for applications requiring both structural performance and thermal insulation, offering a sustainable alternative to conventional materials in response to growing environmental demands.

Published: November 2024

ABSTRACTBoards of directors are vital to firm performance and are an integral part of the decision‐making process of any business. Several studies have been conducted that observe corporate or nonprofit board characteristics, skills, and the board's connection to firm performance. In the cooperative space, the literature has focused on exploring the impact directors have on governance and policy. Only a few studies have examined director skills. The present study adds to this literature by identifying the skill gaps for directors of US farmer cooperatives, and what skills are most important for a director to possess. We found that the largest skill gaps were in cooperative governance and policy and cooperative finance. Time management was found to be the least important skill for directors to possess. Asking critical questions, strategic planning, and understanding current economic and industry conditions were consistently among the top three skills.

Published: November 2024

AbstractBACKGROUNDApproximately 40% of people aged ≥ 65 experience memory loss, particularly in episodic memory. Identifying the genetic basis of episodic memory decline is crucial for uncovering its underlying causes.METHODSWe investigated common and rare genetic variants associated with episodic memory decline in 742 (632 for rare variants) Ashkenazi Jewish individuals (mean age 75) from the LonGenity study. All‐atom molecular dynamics simulations were performed to uncover mechanistic insights underlying rare variants associated with episodic memory decline.RESULTSIn addition to the common polygenic risk of Alzheimer's disease, we identified and replicated rare variant associations in ITSN1 and CRHR2. Structural analyses revealed distinct memory pathologies mediated by interfacial rare coding variants such as impaired receptor activation of corticotropin releasing hormone and dysregulated L‐serine synthesis.DISCUSSIONOur study uncovers novel risk loci for episodic memory decline. The identified underlying mechanisms point toward heterogenous memory pathologies mediated by rare coding variants.Highlights
We demonstrated the contribution of the common polygenic risk of Alzheimer's disease to episodic memory decline.
We discovered and replicated two risk genes associated with episodic memory decline implicated by rare variants, were discovered and replicated.
We demonstrated molecular mechanisms and potential novel memory pathologies underlying interfacial rare coding variants.
Molecular dynamics simulations were performed to understand the downstream effects of risk rare coding variants.
Association of precuneus Aβ burden with default mode network function

Published: November 2024

AbstractINTRODUCTIONIt remains unclear whether the local amyloid‐beta (Aβ) burden in key regions within the default mode network (DMN) affects network and cognitive functions.METHODSParticipants included 1002 individuals from the Chinese Preclinical Alzheimer's Disease Study cohort who underwent 18F‐florbetapir positron emission tomography resting‐state functional magnetic resonance imaging scanning and neuropsychological tests. The correlations between precuneus (PRC) Aβ burden, DMN function, and cognitive function were investigated.RESULTSIn individuals with high PRC Aβ burden, there is a bidirectional relationship between DMN local function or functional connectivity and PRC Aβ deposition across various cognitive states, which is also linked to cognitive function. Even below the PRC Aβ threshold, DMN function remains related to PRC Aβ deposition and cognitive performance.DISCUSSIONThe findings reveal the critical role of PRC Aβ deposition in disrupting neural networks associated with cognitive decline and the necessity of early detection and monitoring of PRC Aβ deposition.Highlights
Precuneus (PRC) Aβ burden impacts DMN function in different cognitive stages.
High PRC Aβ burden is linked to early neural compensation and subsequent dysfunction.
Low PRC Aβ burden correlates with neural changes before significant Aβ accumulation.
Changes in DMN function and connectivity provide insights into AD progression.
Early detection of regional Aβ burden can help monitor the risk of cognitive decline.

Published: November 2024

AbstractINTRODUCTIONProgression to Alzheimer's disease (AD) dementia from normal cognition (NC) can follow different trajectories, with most progressing through a recognizable mild cognitive impairment stage (NC–MCI–AD), while some individuals transition quickly from NC to AD dementia (NC–AD).METHODSWe compared demographic characteristics, health factors, and cognitive and functional assessments across three time points: the first NC visit, the last NC visit, and the first AD dementia visit.RESULTSThe NC–MCI–AD group showed greater impairment in cognitive and functional scores at AD dementia diagnosis, despite maintaining better cognitive function during the NC stage. Analysis of yearly changes revealed negligible differences during NC. However, the yearly change during the AD dementia stage suggested potentially more rapid functional decline in the NC–AD group.DISCUSSIONThese findings highlight the heterogeneity in AD disease progression and emphasize the importance of considering diverse progression patterns in AD research and clinical practice.Highlights
We investigated the disease progression difference between patients who converted to Alzheimer's disease (AD) dementia from normal cognition (NC) directly or through the mild cognitive impairment (MCI) stage.
We found that the NC–MCI–AD group showed greater impairment in cognitive and functional scores at AD dementia diagnosis.
We discovered that the NC–AD group had rapid functional decline once patients were confirmed with AD onset.

AbstractINTRODUCTIONPatterns of signal from tau positron emission tomography (tau‐PET) confined to the medial temporal lobe (MTL) or extended into the neocortex may be relevant for Alzheimer's disease (AD) research if they are linked to differential biomarker levels and cognitive decline.METHODSVisual assessment of Tau‐PET [F‐18]florquinitau (FQT) exams from 728 initially non‐demented older adults yielded four uptake groups: tau‐negative (T−), MTL‐only (T+MTL), neocortex‐only (T+Neo), or both (T+MTL&Neo). Mixed effects models assessed group differences in retrospective cognitive and plasma pTau217 trajectories.RESULTST+MTL&Neo was the most common T+ group (n = 97; 93% A+) and exhibited the sharpest worsening in cognitive and pTau217 trajectories before tau PET.DISCUSSIONThe T+MTL&Neo category represents an intermediate to advanced stage of AD preceded by rising ptau217 and progressive cognitive decline. The pTau217 finding suggests that A+, T+ in MTL or neocortex could represent early AD stages, with a higher likelihood of progressing to more advanced stages.Highlights
Visual assessments of Tau‐PET FQT revealed four distinct uptake groups: tau‐negative (T−), MTL‐only (T+MTL), neocortex‐only (T+Neo), or both (T+MTL&Neo).
Amyloid positive participants in the T+MTL and T+MTL&Neo categories showed a retrospectively faster decline in their cognitive trajectories, and a sharper increase in pTau217 levels in plasma, compared to T−.
The T+MTL&Neo group displayed sharper trajectories compared with the other Tau positive groups in both their cognitive scores and pTau217 plasma levels.
Our results suggest that participants with Tau present in both MTL and neocortex represent an intermediate to advanced stage of AD, whereas participants with signals confined to either MTL or neocortex could represent earlier AD stages.
