Reliability-based versus allowable stress design of foundations for the Center for Missouri Studies building
Authors:   , Dummerth Nathaniel Frank
Published: April 2021

Uncertainty in design parameters is inherent to the field of geotechnical engineering. Allowable stress design has conventionally been used for foundation design and accounts for uncertainty in geotechnical parameters and consequences of failure by assigning a global factor of safety. Allowable stress design is typically a conservative approach and may result in increased construction costs. The objective of the thesis is to compare allowable stress design with reliability-based design of foundations. The secondary objective is to initiate a 'living' database of geotechnical parameters for the University of Missouri - Columbia Campus, which will be expanded by future graduate students. A geologic history and site investigation results are presented to characterize subsurface conditions for the Center for Missouri Studies building in Columbia, Missouri and are entered into the geotechnical database. The existing foundation system of the Center for Missouri Studies building is evaluated using allowable stress design methods. The existing foundation system is reconsidered using reliability-based design. In a reliability-based design, uncertainty is quantified by evaluating the distribution of geotechnical strength parameters and structural loads. Two alternative foundation types are also considered. Reliability-based design was shown to be less conservative than allowable stress design. Both methods produced safe and reliable results, but foundation costs were reduced by seven (7) to thirty-five (35) percent when reliability-based design was used. The probability of failure of the foundations was acceptable from both design methods, but was unnecessarily conservative when using allowable stress design. A final objective of the thesis is to provide a template for future geotechnical engineering students to assemble an interactive geotechnical database and detailed subsurface profile for the University of Missouri-Columbia Campus. Appropriate use of the database and increased implementation of reliability-based design can reduce future design and construction costs of local foundations while assuring acceptable levels of reliability.
A sustainable livelihood resource evaluation of communities that participated in a livestock development project a decade ago
Authors:   , Earl Kendra Alice
Published: April 2021

Livestock projects are a popular type of development activity to provide resources that farmers can use to positively change their livelihoods. Recently NGOs have been moving towards more holistic approaches of monitoring and evaluating their development projects. While this is creating a more complete picture of immediate impacts in the community, there are short-term constraints due to the time frame in which the monitoring and evaluation occurs. This research used the sustainable livelihoods framework's livelihood capitals to determine what the long term impact of a livestock development project was on several areas in the Altiplano Highlands of southern Peru. The Heifer Project International's Alpaca Biodiversity Project was active from 2004-2007. Through a simple categorical analysis, the results determined that the area with the most enabling environmental factors saw the greatest Long-run benefits. The livestock project's livelihood capital resources contributed to the area were able to have a moderate to strong positive impact and be maintained because of the existing environmental factors. In the other area's the project's livelihood capital resources had adverse impacts according to the farmers interviewed. Overall, the area in which the project exists needs to have environmental factors that provide for the primary needs of the community, thus allowing for the farmers to fully utilize their available livelihood capital resources and new livelihood capital resources introduced by the project.
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
Authors:   , Martin Cooper Daniel
Published: April 2021

Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel in production and research alike. Experiments were conducted in 2 studies to investigate aspects of nutrition and animal health in receiving cattle. Blood chemistry and immune components of sick and healthy cattle, along with feed intake, growth, and feed efficiency were evaluated for methods potentially useful in BRD diagnosis or offsetting performance losses. Intake, blood chemistry analysis, and immune proteins known as acute phase proteins provided patterns with possible complementarity for more accurate objective BRD diagnosis. Feed efficiency was improved by supplementing amino acids to exceed nutrient requirements. Utilizing these findings could provide incremental improvements in the current stalemate against BRD, improving both beef industry profitability and animal welfare.
The role of place in assisted living
Authors:   , Molnar Rachel M.
Published: April 2021

The qualitative inquiry explored what physical attributes and tangible items that assisted living residents at one facility determined to be personally meaningful and emblematic of their concept of 'home.' Using grounded theory methods, in-depth interviews and participant-captured photographs were employed to investigate the research questions. Through the coding and analysis process, interview transcripts and photographic data indicated two major themes of value. The first, facility characteristics, highlighted factors associated with the assisted living environment, including the general culture and level of social engagement with members of the community, group activities coordinated by the facility itself, and the resident's personal one or two bedroom apartment. The other, individual characteristics, focused on aspects that the resident introduced into the environment, such as personal values and priorities, memories, and hobbies. The data suggests that all six of the characteristics contributed meaning to a resident's experience in assisted living and shaped their perceptions of 'home,' although the individual's unique character may determine which attributes are the most influential to him or her.
A Bayesian hierarchical model of lexicographic choice
Authors:   , Park Sanghyuk
Published: April 2021

I present a lexicographic, threshold-based model of choice used to evaluate decision makers' preferences among risky alternatives. Using a hierarchical Bayesian frame-work, this model is able to account for observed individual differences by allowing for variable threshold values in attribute features, as well as the order that individuals consider attributes of the choice alternatives. Performance of the model is evaluated via a parameter recovery test using simulated data. I also apply the model to the choice data from a decision-making-under-risk experiment (Davis-Stober, Brown and Cavagnaro, 2015). Bayesian p-values are obtained to check the model fits for every individual, and sensitivity analysis is carried out to measure the degree to which choices of prior distributions affect the results. Finally, I discuss the implications of the Bayesian hierarchical model of lexicographic choice I present in this paper.
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
Authors:   , Schrum Matthew Christopher
Published: April 2021

Freshwater mussels are among the most threatened aquatic fauna in North America. Given the need for continued monitoring of threatened mussel species, an evaluation of the effectiveness of metrics from visually-based sampling methods is an essential step in assessing populations. We surveyed 14 sites in the Meramec River Basin in East-central Missouri to determine the effectiveness of visual sampling methods and to determine the effects of habitat variability on the effectiveness of these methods. At each site, we employed three visual methods for estimating mussel abundance; timed visual searches (TVS), systematic strip transects, and stratified randomly placed visual 0.25 m2 quadrats. We excavated substrate at each 0.25 m2 quadrat to determine baseline densities for each species. We compared the results of density estimates or CPUE of each visual method with density estimates based on excavated quadrat samples, which we considered the most rigorous of our sampling approaches and a useful baseline. Sampling efficiencies (SE) of visual-based quadrats were calculated and used to determine if visual techniques provide reasonable approximations of overall mussel abundances and to investigate factors that influenced SE. Sampling efficiency averaged 0.45 (Std. Err. = 0.05) across species, and varied greatly among taxa and the 3 rivers included in this study, and was influenced by temperature, discharge, and, to a lesser extent, by other factors. Correspondence of TVS and transects with excavation varied amongst taxa, but was typically low, and was affected inconsistently by habitat factors. Species detection probabilities were highest for TVS (0.45 - 1.00, mean = 0.84) and lowest for visual quadrats (0.17 - 1.00, mean = 0.71; strip transects had intermediate values (0.23 - 1.00, mean = 0.75). Detection probabilities for most species were not affected by habitat variability, those that were affected, were inconsistent. These results will be used to produce validated and standardized sampling protocols for freshwater mussels of Missouri.
Hillary Clinton's political campaign communication in the interactive Facebook world
Authors:   , Schumacher Megan
Published: April 2021

This research uses content analysis to examine the role of social media in modern American political communication. The purpose of this study is to explore the relationship between different message strategies and level of engagement by focusing on Hillary Clinton's Facebook posts between October 1, 2016, and November 7, 2016, just prior to the campaign election. Agenda-setting theory will be examined in relation to political campaigns' increasing ability to engage voters directly via social media. The number of interactions via Facebook's native buttons will provide a way to measure interactions. It's important to know what message strategies are most effective on Facebook because the more interactions a post receives, the more widely that message has the potential to be distributed via newsfeeds. According to the receive-accept-sample model of information processing, exposure to a message can affect people's opinions and behaviors, so future political campaigns could benefit from the current research by using its findings when determining message strategies.
Relative depth estimation from single monocular images with deep convolutional network
Authors:   , Yang Alex
Published: April 2021

Depth estimation from single monocular images is a theoretical challenge in computer vision as well as a computational challenge in practice. This thesis addresses the problem of depth estimation from single monocular images using a deep convolutional neural fields framework; which consists of convolutional feature extraction, superpixel dimensionality reduction, and depth inference. Data were collected using a stereo vision camera, which generated depth maps though triangulation that are paired with visual images. The visual image (input) and computed depth map (desired output) are used to train the model, which has achieved 83 percent test accuracy at the standard 25 percent tolerance. The problem has been formulated as depth regression for superpixels and our technique is superior to existing state-of-the-art approaches based on its demonstrated its generalization ability, high prediction accuracy, and real-time processing capability. We utilize the VGG-16 deep convolutional network as feature extractor and conditional random fields depth inference. We have leveraged a multi-phase training protocol that includes transfer learning and network fine-tuning lead to high performance accuracy. Our framework has a robust modular nature with capability of replacing each component with different implementations for maximum extensibility. Additionally, our GPU-accelerated implementation of superpixel pooling has further facilitated this extensibility by allowing incorporation of feature tensors with exible shapes and has provided both space and time optimization. Based on our novel contributions and high-performance computing methodologies, the model achieves a minimal and optimized design. It is capable of operating at 30 fps; which is a critical step towards empowering real-world applications such as autonomous vehicle with passive relative depth perception using single camera vision-based obstacle avoidance, environment mapping, etc.
New model of flying sidekick traveling salesman problem with a charge-station
Authors:   , Zhou Pengkun
Published: April 2021

Cooperation between a truck and a drone for last-mile delivery has been viewed as a way to help make more efficient ways of delivery of packages because of the great advantage of drones delivery. This problem was described and formulated a as FSTSP by Maurry and Chu. Because of the weakness concerning drones' batteries lifespan, this paper proposed a new delivery scenario in which a charge-station will be applied in the truck-drone delivery network to increase the performance of the last-mile delivery. This new delivery problem is formulated for the first time in this thesis as a multi-objective problem. The purpose of this is to address both transportation cost and total time consumption. Data analysis is conducted to explore the relation between factors and the overall objective. The analysis shows that a charge-station will significantly increase the performance of the last-mile delivery. Lastly, future work is discussed that will enhance the model even more and possibly lead to better ways to use drones for delivery.
The prevalence of extra-lethal violence across cultures in warfare
Authors:   , Johnson Aaron Z.
Published: April 2021

Extra-Lethal Violence, a form of physical aggression that goes beyond the necessity to kill someone, presents a conundrum: it is inefficient and dangerous to produce, especially during warfare. Extra-Lethal Violence, particularly when it manifests in warfare, does not contribute to the immediate survival of individuals; the time, effort, and lack of awareness of surroundings or other attack suggests that Extra-Lethal Violence could be maladaptive at the individual level or in the short term. Yet this individually risky behavior that seems to have no direct benefit to the aggressor is both common and persistent across time and space. We utilized the electronic Human Relations Area Files (HRAF) to conduct a cross cultural analysis of the prevalence and potential predictors of Extra-Lethal Violence. Our research indicates that Extra-Lethal Violence is present across all populated regions of the world, for the entire timespan of the ethnographic record up to the ethnographic present, across subsistence, marriage, and social complexity levels. Our research suggests that Costly Signaling Theory (CST) is currently the best explanation for this behavior. Extra-Lethal Violence can be characterized as a difficult to fake, clear indicator of martial skill and physical fitness that has a high broadcast efficiency, both within and between groups. Rather than allowing behaviors such as Extra-Lethal Violence to be labeled as 'abhorrent' or 'disgusting,' we must view Extra-Lethal Violence in the same light as the cavalry, the ironclads, or nuclear weapons: societies seeking a decisive advantage over their enemies, utilizing available resources, be they material or behavioral.
Effects of stand density on mitigation and adaptability to climate change in pine and hardwood forests of Missouri
Authors:   , Anderson Samantha E.
Published: April 2021

Understanding how forests respond to traditional management in the context of climate change is increasingly important for developing multi-objective management strategies. In the Missouri Ozarks, the influence of long-term forest management on climate mitigation and adaptation potential is largely unknown. Using data from two long-term thinning studies, we determined the influence of stand density on carbon dynamics and drought response in the Missouri Ozarks. First, carbon storage and sequestration rates of even-aged short leaf pine and upland oak forests were assessed to better understand the role of manipulating stand density in mitigating climate change. Next, we developed a short leaf pine tree ring-width chronology to determine the influence of thinning on tree-level growth response during a severe drought. Results offer valuable information to land managers regarding the effects of stand density and traditional management practices on mitigation and adaptation to climate change in the Missouri Ozarks.
An essay on the burden of proof
Authors:   , Chambers Wesley A.
Published: April 2021

This essay answers two questions: what is a burden of proof, and when is it reasonable to assign a burden of proof? After showing the importance of how we answer these questions, it uses the Western legal tradition as the starting point and paradigm for a normative account of burden of proof. It is normative because it argues that a reasonable burden of prove presupposes the existence of objective rights and obligations. On the account, the burden is a conditional demand for sufficient evidence and is reasonable if its correlative presumption is reasonable. A presumption, e.g., the presumption of innocence in law, is taken as a conditional acceptance of a proposition. What makes a presumption reasonable is a person or group of persons having a conditional right or obligation to accept the proposition in question, i.e., to act as if it is true. After presenting the account's explanatory power and the sources from which rights and obligations may arise, this essay shows how the burden of proof may apply in non-legal settings. It concludes by applying the account to the question whether believers in God bear a burden to prove their position, arguing that there is no such burden.||Abstract from public.pdf.
Endothelial phenotype differs by both sex and vessel function
Authors:   , Kemp Scott S.
Published: April 2021

Endothelial cells (the cells that line our blood vessels) were once thought to be an inert cellophane-like wrapper separating flowing blood from tissue. However, as our understanding of the human body has progressed, we have come to know that the endothelium is actually an incredibly important, metabolic ally active organ. Endothelial dysfunction appears to be an early hallmark of multiple disease states, including, but not limited to, cardiovascular disease, type II diabetes, and atherosclerosis. While it is often presumed that all non-specialized endothelial cells are the same, and thus will have the same response to various pharmacological agents, disease states, and stimuli, this may not be true. Our goal is to understand if endothelial cell phenotypes (characteristics expressed by the cell) vary based on their origin (the blood vessel they come from), or by sex, and if so, to what degree. Specifically, our research focused on primary cultures of aortic (a conduit vessel) endothelial cells and of skeletal muscle microvasculature (exchange vessels) endothelial cells from both male and female rats, then compared them to one another, after being grown under identical conditions. Our results strongly suggest that endothelial cells vary in size, growth rates, and protein expression, based on their origin and their sex. The implication is that medicines could affect different parts of our bodies indifferent ways, as well as affecting males and females differently. When studying functions mediated by vascular endothelium, it is important to use cells from an anatomical/functional location that best describes the question under investigation (or multiple locations if looking systemically), AND both sexes, as both characteristics determine the phenotype.
Chemically-induced controlled growth of CsPbBr3 perovskite nanocrystals
Authors:   , Goriacheva Mariia
Published: April 2021

Trihalide perovskite nanocrystals have recently emerged as a new class of superior nanoscale semiconductors due to their outstanding optoelectronic properties. A family of all-inorganic CsPbX3 (X=Cl, Br, and I) perovskite nanocrystals is of a particular interest, due to its higher resistance to moisture, heat, and continuous irradiation. In this thesis work a novel chemical route was designed and studied for inducing the growth of CsPbBr3 perovskite nanocrystals at room temperature by intentional depletion of stabilizing ligands, leading to the nanocrystals' fusion. The growth of nanocrystals was achieved from 8 nm to 35 nm in average lateral dimensions, while preserving their optical and colloidal integrity. The thickness was found to be approx. 14 nm. Both UV-visible absorption and photoluminescence emission spectra indicated a red shift in the grown nanocrystals, compared to that of as-synthesized 8 nm nanocrystals. It was determined that the growth of NCs happened in all three dimensions, supporting the theory of induced fusion. The discovered chemical route for triggering post-synthetic growth of as-synthesized perovskite nanocrystals offered a new perception on understanding the role of stabilizing surfactants on the surface of perovskite nanocrystals. It was shown experimentally that the ligands not only participated in colloidal stabilization and photoluminescence enhancement, but also could be efficiently employed for post-synthetic manipulation of nanocrystals' size, band gap and shape.
Evaluation of the geologic CO[subscript 2]sequestration potential of the Morrow B sandstone in the Farnsworth, Texas hydrocarbon field using reactive transport modeling
Authors:   , Khan Riaz Hossain
Published: April 2021

The objectives of this research were to examine the long term fate of CO[subscript 2] injected into the Morrow B Sandstone, a hydrocarbon reservoir in the Farnsworth Unit in northern Texas. A suite of numerical multiphase reactive transport models was constructed simulating continuous and water-alternating-gas (WAG) CO[subscript 2] injection through nine wells into an initially water-saturated reservoir. The simulations predicted little change in the pressure or temperature of the reservoir as a result of fluid injection. However, the injectedCO[subscript 2] temporarily reduced the pH of the formation water from near neutral to as low as 4.7, which induced further changes in the formation water composition and reservoir mineral matrix. Much of the injected CO[subscript 2] also initially existed as a separate immiscible gas phase, but this CO[subscript 2] appears to have leaked vertically through the overlying Morrow Shale cap rock and disappeared from the Morrow B Sandstone within 30-50years. However, some of the injected CO[subscript 2] dissolved into the Morrow B formation water and migrated westward. This acidified CO[subscript 2]-enriched formation water initially dissolved native calcite and ankerite in the reservoir but later in the simulations calcite, dolomite, and siderite began to precipitate, serving as minor sinks for CO[subscript 2]. Among non-carbonate minerals, albite and illite, both initial constituents of the Morrow B Sandstone matrix, were predicted to dissolve, whereas quartz, kaolinite, and smectite were predicted consistently to precipitate. However, these changes in mineral precipitation and dissolution caused negligible changes in porosity on the order of only 0.001%, causing correspondingly negligible changes in the patterns of fluid flow and CO[subscript 2] storage capacity of the Morrow B Sandstone. Based on the results of the simulations, because of significant leakage of CO[subscript 2] through the overlying Morrow Shale, the Morrow B Sandstone is judged to be a minor reservoir for CO[subscript 2] sequestration for at least decadal to century time scales, where the CO[subscript 2] is sequestered primarily in aqueous solution in the Morrow B formation water. However, petroleum, a likely major sink for injected CO[subscript 2], was not considered in the models and likely would significantly improve the CO[subscript 2] sequestration capacity of the Morrow B Sandstone.
Modeling, characterization and evaluation of MU100 high-energy density ceramic nanodielectric for use in pulsed power applications
Authors:   , Howard Alexander B.
Published: April 2021

A high dielectric, nanodielectric, composite material, MU100, was developed by the University of Missouri for use in dielectric loaded antennas. Based on its dielectric strength and losses, MU100 had possible uses in the development for high energy-density capacitors. This work presents the theory behind, methods of preparation and evaluation, modeling and properties of MU100. MU100â€™s dielectric properties are explored in high energy-density pulsed power applications, compact high voltage capacitors. Small scale tests have shown the average dielectric strength of MU100 to be 225 kV/cm with a peak break down field of 328 kV/cm. When potted, these small-scale capacitors have lifetimes in excess of 800,000 discharges at 80% of their maximum rated field strength. This shows a remarkable development in the performance of high energy density capacitors for use in pulsed power applications.
Influence of Teacher-Student Relationship on Academic Performance: The Case of Tirana
Authors: Mucaj Arjana , Ibrahimi Silva , Gjoka Denisa
Published: April 2021

The aim of the current study is to assess the impact of the teacher-student relationship on the academic performance of students 12 to 15 years old in the Albanian context. The analysis and evaluation of this relationship is an important issue as a qualitative relationship between them contributes not only to the students’ academic but also to their socio-emotional development. The sample was composed by 121 students selected on three 9-years school of Tirana. Factorial analysis by the statistics method showed that the internal factors that influence the teacher-student relationship were related to individual traits as temperament, personality, ability, and psychological effects. It is precisely the role of the teacher through communication and meeting the needs of the student that influences the student’s perception of behavior, competence, care, and support from the teacher. Classroom climate was an external factor that also affect the teacher-student relationship. It is precisely positive relationships that induce a good environment and foster motivation and high results. A qualitative teacher-student relationship affects academic and psycho-social development of student in the class.

Published: April 2021

This research paper presents the preliminary findings of a homonymous project, which aims to study the literary production of nikkei (people of Japanese descent) in the state of Mato Grosso do Sul in Brazil. This project investigates the existence of this production and intends to study it as part of contemporary Brazilian literature. The scope of the research considers the nikkei production as one of the evidences that show the process of hybridization to which Stuart Hall refers in his text "The question of cultural identity"(1992). It also seeks to discover the historical and geographical context of this production as well as aspects related to Japanese immigration in the state, even before its emancipation.

Resumo: No debate contemporâneo sobre a necessidade de repensar e redimensionar os commons em sentido global, as vivências estabelecidas entre humanos e mundo natural de origem cabocla no sul do Brasil vieram a construir, historicamente, diferentes formas de uso da terra, de sociabilidade, de expressão da religiosidade e de relações de vizinhança. Na região sul do Brasil são denominados faxinais. Pesquisas que abordam o tema das cuidadoras familiares como cuidadoras informais pontuam a precarização da função no sentido de não percepção de remuneração pela atividade exercida, bem como a não capacitação técnico-científica para o desenvolvimento da atividade. Sendo este um trabalho atribuído às mulheres nos faxinais. O tema do cuidado prestado ao idoso em fim de vida torna-se cada vez mais relevante no meio cientifico pelo aumento crescente da população idosa e a frequência de doenças crônicas que evoluem para necessidade de cuidados no fim de vida. Pensar sobre o processo de morte e morrer a partir da visão dos familiares contribuem para a compreensão social e dos profissionais de saúde em como melhorar a assistência prestada às famílias de uma comunidade e que constroem novos olhares sobre a finitude da vida. Quer seja em sociedades urbanas ou em rurais tradicionais, a vivência do cuidado ao idoso em fim de vida pode ser semelhante, uma vez que seu processo e sua performatividade geram reflexões e influências com significativas assimetrias de gênero.

ANÁLISE DAS POTENCIALIDADES E DESAFIOS DO DESENVOLVIMENTO DO TURISMO EM PRESIDENTE EPITÁCIO-SP E SUAS IMPLICAÇÕES NA EXPLORAÇÃO DOS RECURSOS HÍDRICOS
Authors: Oliveira Suélen Daianne de , Tommaselli José Tadeu Garcia , Romero Danielli Cristina Granado
Published: April 2021

Reservatórios de usinas hidrelétricas são ecossistemas artificiais de grande importância que proporcionam usos múltiplos, inclusive para o turismo. A atividade turística no reservatório da UHE Engenheiro Sérgio Motta tem sido indutora do desenvolvimento local para o município de Presidente Epitácio-SP. Porém, sem planejamento adequado e monitoramento constante, há grandes possibilidades de que o turismo cause impactos significativos, o que pode comprometer a qualidade dos recursos hídricos e afetar as atividades desenvolvidas no reservatório, a longo prazo, principalmente, a pesca e o banho. A presente pesquisa tem como objetivo analisar o desenvolvimento da atividade turística em Presidente Epitácio, considerando de que forma ela impacta (negativa ou positivamente) os recursos hídricos. Como procedimento metodológico foi realizado um levantamento bibliográfico e documental, além de entrevistas com representantes do poder público municipal e empreendedores locais. O reservatório é apontado nas entrevistas, como o principal motivador da atividade turística. O corpo d’água pode ser impactado pelo turismo em razão das ocupações às margens do reservatório que, na maioria dos locais, não possuem sistemas de coleta e tratamento de esgoto, bem como nos pontos turísticos. Convém mencionar os possíveis impactos que podem ser causados na ictiofauna devido a pesca predatória e o volume de resíduos gerados pela atividade, que se torna um fator de risco ao corpo hídrico em razão dos serviços de limpeza ineficientes. Entende-se que a gestão e os empreendedores locais precisam ter em mente que a degradação dos ambientes naturais é prejudicial ao turismo, pois tratam-se dos principais atrativos do município.
CONDOMÍNIOS HORIZONTAIS E A OCUPAÇÃO DE VAZIOS URBANOS NA CIDADE
Authors: Reis Edileia Barbosa , Viana Bartira Araújo da Silva
Published: April 2021

Este artigo teve por objetivo discutir o uso e ocupação de vazios urbanos por condomínios horizontais na região Sul de Teresina-Piauí. Esses espaços representam a força dos promotores imobiliários e dos proprietários fundiários no uso e ocupação da terra, em especial em áreas de expansão da cidade, locais esses disputados para instalação de condomínios horizontais. Nessa perspectiva, para a construção do referencial teórico, contou-se com o diálogo sobre a expansão de cidade dispersa e os vazios urbanos, com Corrêa (1989); promotores imobiliários e proprietários de terra, com Lefebvre (2001); o direito à cidade, com Nascimento Júnior (2017) entre outros. Acrescenta-se ainda que a elaboração do estudo pautou-se, metodologicamente, na escolha do método dialético, assim como na pesquisa bibliográfica, documental e de campo, com a aplicação de questionários e o uso de mapas e imagens de satélite. Foi detectado que a expansão urbana de Teresina é fruto de um processo descontínuo que apresenta vazios urbanos em áreas de expansão sem finalidade social, sendo que tais áreas estão sendo ocupadas por condomínios horizontais fechados de baixo padrão. Desse modo, constatou-se que os condomínios horizontais provocam rearranjos espaciais em áreas de vazios urbanos, gerando o processo de segregação espacial e impactos ao meio urbano. What do you want to do ?New mailCopy
TRABALHO FORMAL, INFORMAL E ORDENAMENTOS JURÍDICOS NA RECICLAGEM BRASILEIRA
Authors: Xavier da Cruz Uilmer Rodrigues , Garcia Ricardo Alexandrino
Published: April 2021

No mundo contemporâneo, torna-se cada vez mais importante discutir as relações de trabalho decorrentes da ascensão do capitalismo. O presente artigo representa um esforço nesse sentido, debruçando-se justamente sobre essa temática. Parte-se, aqui, de dois conceitos cunhados por Marx e Engels, os de trabalho formal e trabalho informal, sob a ótica das relações trabalhistas no contexto das atividades de catação e reciclagem, precisamente dentro da realidade brasileira. Tais atividades consistem em um ofício contraditório, pois, ainda que possuam um grande valor social e ambiental, seus operadores não recebem o devido reconhecimento, por seu trabalho se basear no recolhimento dos restos do consumo do Outro. Pensando nisso, é imprescindível refletir sobre os motivos que levam o capitalismo a incentivar atividades marginalizadas como essas. A hipótese sobre a qual este artigo se alicerça é a de que o capitalismo o faz para manter a superioridade de uma pequena parcela da sociedade, enquanto outra é alvo de superexploração.
INDUSTRIALIZAÇÃO BRASILEIRA: DIÁLOGOS ENTRE CAIO PRADO JR., CELSO FURTADO, FLORESTAN FERNANDES E IGNÁCIO RANGEL
Authors: NOGUEIRA LEANDRO MENDES
Published: April 2021

Há um diálogo tácito entre grandes intérpretes do Brasil, nem sempre visível num primeiro olhar. Por exemplo, Caio Prado Jr., Celso Furtado, Florestan Fernandes e Ignácio Rangel, apesar de analisarem a sociedade brasileira a partir de fundamentações teóricas distintas, produzem obras que possuem uma agenda de perguntas semelhante e que dialogam entre si. Em especial, há uma preocupação comum em torno de alguns temas sobre o desenvolvimento brasileiro. Neste artigo, faremos a análise de alguns elementos de convergência e de divergência das interpretações dos autores sobre a industrialização brasileira, com o intuito de trazer à tona o diálogo entre eles, e, ao mesmo tempo, situando as contribuições que oferecem para a compreensão da industrialização. Para tanto, utilizaremos obras fundamentais desses autores: “A Revolução Brasileira” (2004) de Caio Prado Jr.; “Formação Econômica do Brasil” (2003) e “O Mito do Desenvolvimento Econômico” (1974) de Celso Furtado; “A Revolução Burguesa no Brasil” (1975) e “Sociedade de Classes e Subdesenvolvimento” (2008) de Florestan Fernandes; e as “Obras Reunidas” (2005) de Ignácio Rangel.

A erosão hídrica contribui para a degradação dos solos e assoreamento de rios e reservatórios de água. A identificação de áreas suscetíveis à erosão pode ser obtida utilizando modelos matemáticos em conjunto com técnicas de geoprocessamento. Sendo assim, o objetivo deste estudo foi analisar a distribuição pluviométrica e estimar o fator de erosividade da chuva para o Vale do Ribeira. Para isso, foram utilizados dados pluviométricos, o fator R da Equação Universal de Perdas de Solo (EUPS) e o processo de interpolação pelo método Inverse Distance Weighting (IDW). Os valores obtidos para a erosividade da chuva demonstraram uma alta variabilidade do potencial erosivo com amplitude de 5.360,6 MJ.mm.h-1.ha-1 a 9,278,75 MJ.mm.h-1.ha-1. As áreas que apresentaram maior potencial erosividade das chuvas foram as regiões Norte e Nordeste do Vale do Ribeira e, consequentemente, são as mais vulneráveis às intervenções antrópicas não conservacionistas.

AbstractIn the contemporary world, it becomes more and more important to discuss the work relations that are decurrent of capitalism’s ascension. The present article represents an effort in this sense, dwelling precisely in this theme. Two concepts coined by Marx and Engels are utilized here, which are the ones of formal and informal work, under the optics of work relations inside garbage collection and recycling, precisely inside brazilian reality. These activities consist in a contradictory duty, because even though they possess great social and environmental values, the workers do not receive the same recognizement, for their work is based on collecting other people’s consumer waste. Having that thought, it is essential to consider the reasons that take capitalism to incentivize such marginalized activities. The hypothesis under which this article is built is that capitalism does it to maintain the eminence of a small portion of the society, while the other is overexploited.Keywords: Formal work.

Stock Assessment of Tenualosa ilisha (Hamilton, 1822) were estimated using FiSAT-II software with length-frequency data collected from different landing centers. The Southeast Coast of Bay Of Bengal, Cox's Bazar. The Von Bertalanffy growth parameters Land K for the species were asymptotic length (L∞) was 51.41 cm, growth rate (K) was 0.75 year-1 and t0 = -0.2 year respectively. The estimated value of total mortality (Z) based on length converted catch curve using these growth parameters was 2.35 year-1.Natural mortality (M) based on growth parameters and mean environmental temperature (T = 27° C) was 1.00 year-1 and fishing mortality (F) was 1.35 year-1. Optimum length of hilsa at first capture (Lc=L50) was 28.36 cm TL. Growth performance indices (ϕ') was 3.30. The estimated value of the exploitation rate (E) using the length-converted catch curve was 0.57. The recruitment pattern of this species was continuous and two peaks per year. The present investigation clearly showed the over fishing (E > 0.50) condition for T. ilisha in Bangladesh. The estimated length-weight relationship for the combined sex was found to be W = 0.0109 L3. Virtual population analysis (VPA) showed that the maximum fishing mortality occurring in the length between 30 to 35 cm with a maximum value in the length of 32 cm that repeatedly indicate high fishing mortality in the T. ilisha. The generalized length-weight relationship was fitted with the pooled data of all monthly samples were BW = 0.029 TL2.718 (R2= 0.833) respectively. The results revealed that all length-weight relationships were highly correlated (r > 0.993). Maximum sustainable yield (MSY) was estimated as 435,554 t.

Published: April 2021

Nesting patterns of four species of mynas and starlings, Common Myna (Acridotheres tristis), Jungle Myna (Acridotheres fuscus), the Asian-pied Starling (Gracupica contra) and Chestnut-tailed Mtarling (Sturnia malabarica) were studied in Jahangirnagar University campus from March to September in 2016. Nests were searched systematically throughout the study area and nesting parameters like nest dimensions, nest-site selection, tree species preference, nesting materials, clutch size and nesting success were examined. A total of 101 nests were recorded where 31 nests were of Common Myna, 10 of Jungle Myna, 49 of the Asian-pied Starling and 11 nests were of Chestnut-tailed Starling. Overall, the sturnids preferred nesting on trees (n=84) to anthropogenic structures (n=17). Common myna showed maximum variation in nest-site selection using tree holes (n=12), tree branches (n=10) and building cornices, holes or crevices (n=9) whereas Chestnut-tailed Starling nested only in tree cavities (n=11). Jungle Myna built nests both in tree holes (n=4) and in building holes and crevices (n=6). The Asian-pied Starlings built their domed nests mostly on tree branches (n=47) where 69% nests were peripheral and 31% were central in position. Out of 20 species of trees utilized for nesting purpose, the majority of nests were built on Whites iris Albizia procera (n=18) followed by Neem Azadirachta indica (n=10) and Mahogany Swietenia mahagoni (n=10). The nests were constructed between 2 and 18m (8±3.8m) from the ground level. Among 19 types of nesting materials recorded, twigs, leaves, straws, grasses, feathers, plastics and polythene were frequently used by all four species while the Asian-pied starling used more rubbish materials than other species. Highest nesting success (80%) was recorded in Common Myna whereas the Asian-pied Starling, Chestnut-tailed Starling and Jungle Myna had 77.8%, 75% and 66.7% of nesting success respectively. Adaptions to using different nesting sites in Common Myna and comparatively higher nesting height in the Asian-pied Starling may have facilitated the greater nesting success.

The study was accomplished to investigate Escherichia coli from two freshwater fish, Tilapia (Oreochromis niloticus) and Mrigal (Cirrhinus mrigala), collected from a fish farm in Sylhet, Bangladesh. Six of each fish were analyzed to isolate and detect Escherichia coli, and E. coli was identified based on morphological and biochemical characteristics. The antibiogram of E. coli was investigated in different generations using eight antibiotic discs such as Chloramphenicol (CH), Streptomycin (S), Gentamycin (G), Ciprofloxacin (CI), Co-trimethoxazole (CO), Azithromycin (AZI), Erythromycin (E) and Novobiocin (NV), and the sensitivity of E. coli was found as 100%, 25%, 100%, 75%, 87.5%, 81.25%, 0%, 0% respectively. Among the 8 antibiotics, for Erythromycin (E) and Novobiocin (NV), the observed resistance pattern of E. coli was 81.25% and 87.5% respectively, whereas, for the rest of the antibiotics, it was 0%.

Pest management relies on proper identification of insect species, which usually depends on morphological keys. In this research, DNA barcoding was used to identify three pest species of genus Aulacophora (A. foveicollis, A. lewisii and A. indica) attacking horticultural crops in Bangladesh. Accurate phylogenetic information and evolutionary divergence data were supported and evidenced by various parameters, including the rates of substitution, nucleotide composition and genetic divergence. The nucleotide composition of these three species indicates that the total adenine and thiamine content (A+T, 67.3%) was higher than the guanine and cytosine content (G+C, 32.87%). Intraspecific genetic divergence ranged from 0.0158-0.1415. To confirm the origin and evolution, phylogenetic tree and haplotype network was drawn. Both the maximum likelihood and neighbor joining analyses showed that A. indica and A. foveicollis were clustered in one group, and A. lewisii was originated from another group. Haplotype showed that A. lewisii has the highest amount of mutational steps among the sequenced pests and genetically distant species from its common ancestors by 78 mutational numbers. Present investigation can be reliably treated for developing reference libraries for species identification via sequence matches and designing specific pest management approach.
