Literatura em perspectiva. Teatros de literatura e perspectivação a partir de Morada Frágil
Authors: Goldfeder André
Published: August 2023

Resumo O artigo aborda Morada frágil ([1999] 2009), singular experimento literário-teatral do escritor, dramaturgo, encenador, pensador de teatro e artista visual Valère Novarina. No centro dessa encenação literária encontram-se agenciamentos de uma visão sobre o problema da perspectiva, que partem do paradigma da perspectiva renascentista em direção a uma concepção perspectiva transversal e transtemporal. Acompanhando os desdobramentos da cenografia enunciativa do texto, propõe-se analisar os modos de encenação que Novarina realiza em torno da perspectiva, complexo técnico, especulativo e poético, articulado a partir de um campo de diálogos entre a literatura, o teatro e a pintura. Assim, busca-se pensar uma noção de teatro de literatura, tomando o espaço literário enquanto espaço de tensionamentos produtivos entre os atos e a (i)materialidade compósita e extremamente ambígua do meio escritural.
Demarcações espectrais: a ideia de ordem em Wallace Stevens
Authors: Cechinel André
Published: August 2023

Resumo A partir da análise do poema “The Idea of Order at Key West”, de Wallace Stevens, o presente artigo propõe-se a discutir o conceito de ordem conforme formulado na obra poética do autor. Diferentemente do trabalho da “nova crítica” [new criticism], que idealiza preservar intactas as fronteiras entre os espaços extrínseco e intrínseco que compõem os artefatos artísticos, a ideia de ordem em Stevens busca tragar para dentro do poema toda a sua exterioridade, reconfigurando criativamente a realidade.
Definições de tipo lexicográfico nas obras de ficção de José Saramago
Authors: Machado José Barbosa
Published: August 2023

Resumo Uma das características da prosa ficcional de José Saramago é a reflexão acerca do uso da linguagem e, em particular, do léxico. Nenhum autor português mais recente tem ou teve uma preocupação tão evidente e reiterada. Nas obras saramaguianas, encontramos a cada passo o autor preocupado em explicar ao leitor a utilização de determinado vocábulo, refletindo acerca da sua origem e das suas particularidades semânticas. Muitas dessas reflexões podem inserir-se naquilo a que em linguística se chama lexicografia implícita (VERDELHO, 1995), que é representada pelo registo no próprio texto de definições de tipo lexicográfico ou dicionarístico. A lexicografia implícita ocorre sempre que um autor apresenta uma definição de uma palavra ou expressão, com o objetivo de clarificar o seu significado ou evitar a ambiguidade. O objetivo desse estudo é identificar nas obras ficcionais de José Saramago as passagens em que o autor apresenta definições de tipo lexicográfico. Tais definições estão bem marcadas no texto e distinguem-se facilmente do resto do discurso, embora façam também parte dele. O segundo termo da definição é muitas vezes introduzido pela forma verbal é, como em “um machuco é um chaparro novo”, servindo-se o autor, no entanto, de outras expressões: quer dizer, isto quer dizer, isto é, significa, maneira de dizer, para quem não saiba, etc.

Authors: Pontón Yolanda Dávila , Narváez Víctor Patricio Díaz , Andrade Bernardo Montero , Terán Joseline Janeth López , Reyes-Reyes Alejandro , Calzadilla-Núñez Aracelis
Published: August 2023

Objetivo: determinar os níveis de empatia em enfermeiros profissionais de um hospital de alta complexidade, relacionar a idade com a empatia (e cada uma das suas dimensões) e verificar se existem diferenças entre esses níveis, de acordo com o tipo de horário de trabalho. Método: delineamento comparativo, correlacional e transversal. A amostra utilizada (n=271) constituiu 40,9% do total de profissionais de enfermagem. Foram estudadas as propriedades psicométricas da Escala de Empatia de Jefferson para Profissionais da Saúde. Foram calculadas estatísticas descritivas: média e desvio padrão. A associação entre empatia e idade foi estimada por meio de equações de regressão e significância estatística dos coeficientes de regressão, após avaliação do tipo de curva por meio de análise de variância. Resultados: o modelo subjacente de três dimensões de empatia foi identificado. Os valores das estatísticas descritivas observados foram relativamente baixos em empatia e suas dimensões. Níveis de empatia não foram associados com a faixa etária. Não foram encontradas diferenças de empatia entre os tipos de horários de trabalho. Foi encontrada variabilidade nas dimensões: “cuidado compassivo” e “colocar-se no lugar do paciente”. Conclusão: esses resultados mostram que os níveis de empatia observados podem implicar em um desempenho deficiente no atendimento empático aos pacientes.

Published: August 2023

Objective: to verify the clinical validity of the proposition of a new nursing diagnosis called perioperative thirst, based on the diagnostic accuracy of its clinical indicators, including the magnitude of effect of its etiological factors. Method: clinical diagnostic validation study with a total of 150 surgical patients at a university hospital. Sociodemographic variables and clinical indicators related to thirst were collected. The latent class analysis technique was used. Results: two models of latent classes were proposed for the defining characteristics. The model adjusted preoperatively included: dry lips, thick saliva, thick tongue, desire to drink water, caregiver report, dry throat and constant swallowing of saliva. In the postoperative period: dry throat, thick saliva, thick tongue, constant swallowing of saliva, desire to drink water, bad taste in the mouth. The factors related to “high ambient temperature” and “dry mouth” are associated with the presence of thirst, as well as the associated conditions “use of anticholinergics” and “intubation”. The prevalence of thirst was 62.6% in the pre and 50.2% in the immediate postoperative period. Conclusion: the diagnostic proposition of perioperative thirst showed good accuracy parameters for its clinical indicators and etiological effects. This proposition in a nursing taxonomy will allow greater visibility, appreciation and treatment of this symptom.

ABSTRACT Background: Several mechanisms, including excessive hunger, account for patients’ difficulties in maintaining weight loss and dietary changes after caloric restriction. Objective: To evaluate the effect of short-term high-fiber calorie-restricted diet in appetite-regulating hormones, and hunger and satiety sensations in women with obesity. Methds: In a randomized controlled trial study, thirty women with body mass index (BMI) higher than 30 kg/m2, and aged from 20 to 50 years were hospitalized following a calorie-restricted diet (1000 kcal/day) for three days. The experimental group (n=15) received high-fiber diet and the control group (n=15), conventional diet. Body weight, BMI, resting energy expenditure (REE), acylated and total ghrelin, leptin, insulin and glucose, and hunger and satiety sensations were evaluated. Linear regression models with mixed effects (fixed and random effects) helped to assess the variables between the two groups and within the groups. Results: Body weight and BMI decreased in both the experimental and control groups (P<0.001). After the high-fiber diet, postprandial acylated ghrelin (P=0.04), glucose (P<0.001), insulin (P=0.04), and leptin (P=0.03) levels as well as the HOMA-IR index (P=0.01) decreased, whereas satiety improved (P=0.02). Obese women that followed the conventional diet had increased body fat percentage (P=0.04) and lower REE (P=0.02). The two diets did not differ in terms of hunger sensation. Conclusion: A short-term high-fiber diet improves satiety sensations and metabolic parameters while suppressing postprandial acylated ghrelin (60 minutes) and maintaining the resting energy expenditure.

Published: August 2023

ABSTRACT Background: Most data on the natural history of portal hypertension come from studies in adults. The morbidity rate of upper gastrointestinal bleeding (UGIB) in children with portal hypertension has not been systematically characterized. Objective: To describe the morbidity and mortality of UGIB in pediatric patients with portal hypertension and identify predictive factors for the occurrence of its main complications. Methods: This retrospective study included pediatric patients with cirrhotic portal hypertension or with extrahepatic portal vein obstruction (EHPVO). Mortality and UGIB complications within a period of up to 6 weeks of the bleeding were investigated. To determine the predictive factors of morbidity, a multivariate analysis was performed using logistic regression; all results were considered significant at P<0.05. Results: A total of 86 patients (51.2% with EHPVO and 48.8% with cirrhosis) had 174 bleeding events. Ascites was the most common complication (43.1% of all cases), being more prevalent in patients with cirrhosis (P<0.001). Cirrhosis was a predictor of the occurrence of any morbidity (OR 20.3). The need for blood transfusion was predictor of at least one complication (OR 5.8), ascites (OR 7.2) and infections (OR 3.8) in the general group and at least one complication (OR 11.3) and ascites (OR 5.8) in cirrhotic patients. The need for expansion was a predictor of any morbidity (OR 4.6) and infections (OR 3.9) in the general group, in addition to being predictor of infection in cirrhotic patients (OR 5.4). There were no deaths from UGIB in the six weeks post-bleeding. Conclusion: The study showed the relevance of morbidity after UGIB in pediatric patients with portal hypertension, especially in those with cirrhosis. The patients with hemodynamic instability requiring blood transfusion or expansion on admission are at increased risk of complications related to upper gastrointestinal bleeding and should be closely monitored.

Resumo O artigo analisa uma experiência de cura da lepra com assacu (Hura crepitans L.), realizada em Santarém, Pará, em 1847, por um indígena chamado Antonio Vieira dos Passos. A experiência passou a ser realizada nas demais províncias do Brasil e também no exterior. Por essa razão, o artigo estabelece relações com práticas médicas realizadas em outras partes do país, tendo como foco o diálogo entre a medicina oficial e a medicina indígena. A análise de matérias de jornais e documentos oficiais revelou que os saberes indígenas sobre o uso de plantas medicinais eram amplamente reconhecidos e utilizados pelos médicos com a intenção de incorporá-los em seu repertório terapêutico.
A ESCOLA NORMAL OFICIAL DE PERNAMBUCO: ESTRATÉGIAS E TÁTICAS DE PRODUÇÃO DA “DOCÊNCIA ESCOLARIZADA” ENTRE OS ANOS DE 1864 E 1880
Authors: Lima Dayana Raquel Pereira de
Published: August 2023

Este texto pretende analisar as estratégias e táticas de formação e certificação docente concedida pela Escola Normal Oficial de Pernambuco (Brasil) entre 1864 e 1880. Por intermédio da  transcrição simples, direta e completa (ARÓSTEGUI, 2006) dos registros documentais nos Anais da Assembleia de Pernambuco,  nas petições remetidas aos deputados provinciais, nos regulamentos da Escola Normal, nas legislações e relatórios da instrução pública, bem como em algumas revistas, mobilizou-se as categorias “experiência” (THOMPSON, 1981), “táticas” e “estratégias” (DE CERTEAU, 1994), visando tecer as maneiras pelas quais as autoridades governamentais, os alunos e alunas normalistas e os docentes públicos primários pernambucanos, em função de suas posições,  construíram significações com relação à produção da “docência escolarizada” – formação de docentes para atuarem no magistério público primário –  promovida pela  Escola Normal. Conclui-se que, de meados da década de 1860 até os anos 1880, a Escola Normal de Pernambuco passou de alternativa indispensável para uma formação com rigor e qualidade teórico, prático e moral da docência pública primária para um lugar cujas práticas internas e externas eram comandadas por politicagens, ou denunciadas, ou abafadas pelo poder público, professores e professoras, alunos e alunas. Os códigos práticos do ofício, há muito conhecidos e aplicados nas práticas de escolarização da sociedade pernambucana (SILVA, 2007) atravessaram e constituíram a formação institucionalizada da docência pública primária no Pernambuco da segunda metade do século XIX.
ENTRE IRMÃS - DOCÊNCIA, SOCIABILIDADE E ESPAÇO URBANO (SANTA CATARINA, PRIMEIRA METADE DO SÉCULO XX)
Authors: Philippi Carolina Cechella
Published: August 2023

Este artigo se ocupa do mapeamento das trajetórias docentes de duas duplas de irmãs – a saber, Antonieta e Leonor de Barros, e Edésia e Iracema Aducci – na capital catarinense ao longo da primeira metade do século XX. Para tanto, tomou como fontes os “Termos de Assentamento do Tesouro do Estado”, disponíveis no Arquivo Público de Santa Catarina, e as notas e reportagens vinculadas na imprensa local, disponíveis na Hemeroteca Digital da Biblioteca Nacional. A série documental, pois, permitiu que fossem rastreados os seus deslocamentos funcionais, bem como seus trânsitos afetivos e sociais. Como referencial teórico, mobilizou as ponderações de Michel de Certeau (1985, 2009), a respeito da operacionalidade e da categorização das práticas, e de Jean François Sirinelli (1996), a respeito da densidade das redes de sustentação e sociabilidade que suportaram as táticas (CERTEAU, 2009) das irmãs. A metodologia aplicada levou em conta a organização de série documental composta por registros pautados nos nomes das supracitadas professoras (GINZBURG, 1989, p. 169-178), ao mesmo tempo que considerou a densidade do uso de fontes digitalizadas na pesquisa histórica (BRASIL; NASCIMENTO, 2020; LUCHESI, 2014). Por fim, destacou a diversidade de trajetórias que compõem a carreira docente, e a forma pela qual essa diversidade engatilhou táticas distintas para permanência na profissão.

Authors: Colmenares-Guillén Luis Enrique , González Yosbeli Delgado
Published: August 2023

Cada hablante posee características lingüísticas particulares condicionadas por las circunstancias de contacto. En la lingüística forense, lingüística aplicada y lingüística de corpus se considera que una regularidad puede ser reconocida como un modus operandi específico y este suele corresponder a comunidades que comparten un mismo fin, con sujetos igualmente precisos, mediante determinadas estrategias lingüísticas. En este artículo se realiza un acercamiento a un perfil lingüístico, correspondiente a potenciales agresores sexuales de infantes, con el fin de obtener un comportamiento lingüístico constante que posteriormente permita reconocerlo en conversaciones online. La metodología empleada en este estudio es empírica, basada en el análisis de lenguaje natural que propone la lingüística de corpus de Rayson. Mediante ella, se analiza el comportamiento lingüístico en la comunicación textual vía online extraído de un corpus (con un procesamiento previo), constituido de cinco conversaciones, en las cuales se estableció la frecuencia léxica para generar diecisiete módulos temáticos. Finalmente, se encontró regularidad en las primeras siete intervenciones, lo que señala un comportamiento lingüístico específico: un perfil lingüístico que podría guiar a un reconocimiento oportuno de las identidades online que representan un peligro para las infancias.
REVVING UP HEAT-TRANSFER PERFORMANCE OF DOUBLE PIPE HEAT EXCHANGER USING DIVERSE MOLAR Ag-GO HYBRID NANOFLUIDS: AN EMPIRICAL AND NUMERICAL STUDY USING CENTRAL COMPOSITE DESIGN
Authors: Armstrong M. , Sivasubramanian M. , Selvapalam N. , Rajaganapathy C. 
Published: August 2023

This study seamlessly integrates empirical and numerical approaches to enhance the efficiency of a double pipe heat exchanger (DPHX) using varied molar concentrations (0.03, 0.06, and 0.09 M) of Ag-doped GO hybrid nanofluids as the working fluids within the heat exchanger's annulus. Remarkable
improvements in the heat exchanger's performance were achieved by increasing the molar concentration of Ag-GO hybrid nanoparticles, along with the Reynolds number (ranging from 250 to 1451) and the mass flow rate (ranging from 8 to 47 g/s) of the hybrid nanofluids. The utilization of a 0.09M Ag-GO hybrid nanofluid at a Reynolds number of 1451 and a flow rate of 47 g/s resulted in outstanding enhancements in heat-transfer coefficient (62.9%), and Nusselt number (33.55%) surpassing the base fluid. The empirical results of Nusselt number and heat-transfer coefficient were optimized and analyzed using the central composite design approach (CCD) with response surface method, incorporating the Graetz number, varied molar concentrations of Ag-GO, and thermal conductivity of the hybrid nanofluids as input factors. The optimized second-order polynomial quadratic equation model demonstrated excellent compatibility and optimal performance of the heat exchanger, supported by variance analysis. Additionally, CCD optimization confirmed a notable desirability function (0.99) and emphasized the significant influence of the input factors on the output responses. In conclusion, the Graetz number exhibited prominent influence among the input factors, alongside the molar concentration and thermal conductivity of hybrid nanofluids, effectively enhancing the performance of the DPHX.
FACIAL EMOTION RECOGNITION BASED ON SELECTIVE KERNEL NETWORK
Authors: Gao Zunhai , Gao Hongtao , Xiang Yuandong
Published: August 2023

Existing deep learning methods for facial emotion recognition only focus on optimizing network structures,
utilizing fixed receptive fields for different images, and relying on feature extraction based on
a single scale of receptive fields. However, this approach fails to fully capture the most critical facial
regions. To address this limitation, this paper presents a novel technique for facial emotion recognition
that employs a selective kernel network. The proposed method introduces a dedicated module called the
selective kernel network, which is trained using transfer learning. This module incorporates various
components, such as a selective attention mechanism and channel-wise independent feature extraction
and fusion. These components allow for the extraction of feature information from key facial regions.
Unlike other methods, the selective convolutional kernel network extracts features with multiple scales
of receptive fields and adapts to different spatial positions using a multilayer perceptron. This adaptability
enhances useful features and suppresses noise. After extracting the features, they are combined,
and the classification outcome is computed using the softmax function. Experimental results demonstrate
that the suggested approach achieves an accuracy of 88.4 and 92.1% on the RAF-DB and KDEF
datasets, respectively. These results confirm the efficacy of the proposed technique in comprehensively
capturing the most crucial facial regions. Moreover, compared to alternative methods, this technique
exhibits superior accuracy and enhanced resilience.
A Review of Cold Atmospheric Plasma Applications in Dermatology and Aesthetics
Authors: Lotfi Mohammadreza , Khani Mohammadreza , Shokri Babak
Published: August 2023

Nowadays, there is a growing use of plasma technology, especially in medicine and aesthetics. Plasma medicine is an innovative, multidisciplinary science combining plasma physics and technology with medicine and life sciences. Billions of dollars are spent annually in the United States to rejuvenate and reduce signs of aging. For this reason, several methods have been created to perform such operations. Methods with different degrees of invasiveness, from cosmetic surgery, like forehead lifts and blepharoplasty, to noninvasive, such as high-intensity focused ultrasound and nonablative lasers, have been used in the field of aesthetics and skin rejuvenation. Plasma can also be used as a noninvasive, minimally invasive, or even invasive method in cosmetic applications such as removing wrinkles and strengthening the skin, that can somewhat replace cosmetic procedures such as blepharoplasty and rhytidectomy. By using various active species, plasma affects biological activities and increases the proliferation and transfer of skin cells. With local application of heat and an increase in proliferation and activity of fibroblasts, the production of type III collagen and elastin density in the skin increases. Plasma can be used to sublimate the skin and remove excess tissue. This article summarizes the most recent studies and clinical trials in dermatology and skin rejuvenation, in which different cold plasma sources (jet and spark) have been used, and examines their results.

Comparison of smoking prevalence in Canada before and after nicotine vaping product access using the SimSmoke model
Authors: Levy David T. , Cadham Christopher J. , Yuan Zhe , Li Yameng , Gravely Shannon , Cummings K. Michael
Published: August 2023

Objectives

The public health impact of nicotine vaping products (NVPs) is subject to complex transitions between NVP and cigarette use. To circumvent the data limitations and parameter instability challenges in modeling transitions, we indirectly estimate NVPs’ impact on smoking prevalence and resulting smoking-attributable deaths using the SimSmoke simulation model.

Methods

Canada SimSmoke uses age- and sex-specific data on Canadian population, smoking prevalence and tobacco control policies. The model incorporates the impact of cigarette-oriented policies on smoking prevalence but not the explicit contribution of NVPs. The model was calibrated from 1999 to 2012, thereby projecting smoking prevalence before NVPs were widely used in Canada. The NVP impact on smoking prevalence is inferred by comparing projected 2012–2020 smoking trends absent NVPs to corresponding trends from two Canadian national surveys. We further distinguish impacts before and after NVPs became regulated in 2018 and more available.

Results

Comparing 2012–2020 survey data of post-NVP to SimSmoke projected smoking prevalence trends, one survey indicated an NVP-related relative reduction of 15% (15%) for males (females) age 15+, but 32% (52%) for those ages 15–24. The other survey indicated a 14% (19%) NVP-related smoking reduction for ages 18+, but 42% (53%) for persons ages 18–24. Much of the gain occurred since Canada relaxed NVP restrictions. NVP-related 2012–2020 smoking reductions yielded 100,000 smoking-attributable deaths averted from 2012 to 2060.

Conclusion

Smoking prevalence in Canada, especially among younger adults, declined more rapidly once NVPs became readily available. The emergence of NVPs into the Canadian marketplace has not slowed the decline in smoking.

Analysis of ER Flux in Cultured Induced Neurons using Keima ER reporters v1
Authors: Hoyer Melissa
Published: August 2023

The endoplasmic reticulum (ER) has a vast proteomic landscape to preform many diverse functions including protein and lipid synthesis, calcium ion flux, and inter-organelle communication. The ER proteome is remodeled in part through membrane-embedded receptors linking ER to degradative autophagy machinery (selective ER-phagy). A refined tubular ER network is formed in neurons within highly polarized dendrites and axons. Autophagy-deficient neurons in vivo display axonal ER accumulation within synaptic ER boutons, and the ER-phagy receptor FAM134B has been genetically linked with human sensory and autonomic neuropathy. However, mechanisms and receptor selectivity underlying ER remodeling by autophagy in neurons is limited. Here, we combine a genetically tractable induced neuron (iNeuron) system for monitoring extensive ER remodeling during differentiation with proteomic and computational tools to create a quantitative landscape of ER proteome remodeling via selective autophagy. Through analysis of single and combinatorial ER-phagy receptor mutants, we delineate the extent to which each receptor contributes to both magnitude and selectivity of ER clearance via autophagy for individual ER protein cargos. We define specific subsets of ER curvature-shaping proteins or lumenal proteins as preferred clients for distinct receptors. Using spatial sensors and flux reporters, we demonstrate receptor-specific autophagic capture of ER in axons, which correlates with aberrant ER accumulation in axons of ER-phagy receptor or autophagy-deficient neurons. This molecular inventory of ER proteome remodeling and versatile genetic toolkit provides a quantitative framework for understanding contributions of individual ER-phagy receptors for reshaping ER during cell state transitions.

The procedure of the mycotoxins determination in wheat grain was developed by LC-MS/MS using modified QuEChERS sample preparation. The method of simultaneous determination of six mycotoxins (aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, T-2 toxin and zearalenone) in wheat grain was validated according to the following criteria: specificity, linearity, limits of detection (LOD), limits of quantification (LOQ), accuracy, and precision. The chromatographic and mass spectrometric conditions for separation and determination of the mycotoxins were optimized during the study. It was established that the most optimal mobile phase for the separation of six mycotoxins is 5 mМ ammonium formate solution in methanol : water : formic acid (5 : 94.9 : 0.1 by volume, eluent A and 95:4.9:0.1 by volume, eluent B). It was found that the correlation coefficients for six mycotoxins range from 0.9990 to 0.9998 (R2 > 0.995). Limits of detection (LOD) and limits of quantification (LOQ) of the mycotoxins are below the maximum permitted levels set by the European Union (EU). Percent recovery in the range from 88 to 103 % indicates the acceptability of the mycotoxin extraction procedure. The relative standard deviation (RSD, %) of the measurement results under conditions of repeatability ranged from 1.94 to 8.76 %. The obtained data suitability evaluation of method (validation) corresponds to criteria European Commission Regulation (EC) No. 401/2006. The validation results showed that LC-MS/MS method with using of modified QuEChERS sample preparation is effective and suitable for the simultaneous quantitation of mycotoxins in wheat grain.

The Clearing: On Black Education Studies and the Problem of “Antiblackness”
Authors: miraya ross kihana , GIVENS JARVIS R.
Published: August 2023

In this essay, authors kihana miraya ross and Jarvis R. Givens make their case for a distinct field of education research—Black education studies, which builds on Black studies and education studies. They explore a key analytic in Black education studies, antiblackness, examining its early and more recent uses as an analytic in education research to forward a more holistic understanding of the concept. In doing so, they highlight the relationship between education as a social institution and the sustained manifestation of antiblackness. The authors conclude by considering how and why scholars might employ Black education studies to center Black life and living.
Security, Conflict Management, and Peacebuilding: Formal Education in Intrastate Political Agreements, 1989–2016
Authors: FONTANA GIUDITTA
Published: August 2023

In this mixed methods analysis of a dataset she developed, Giuditta Fontana explores how formal intrastate peace processes have addressed reforms of for mal education since the end of the Cold War. Looking at the frequency of reforms of formal education, the con text for their inclusion, and the framing of their aims, she finds that intrastate political agreements circumscribe the peace building potential of education because they rarely include education as a component, their geopolitical context and broader content are not clearly associated with the inclusion of education reforms, and education reforms are primarily framed as contributing to security and conflict management rather than long-term peace building. With fundamental implications for scholarship and policy, this article shows that peace agreements’ focus on the promotion of negative peace rather than more ambitious positive peace is an obstacle to realizing the peacebuilding potential of education in conflict-affected contexts.
Upper bounds for PSD propagation time and zero forcing in shadow graphs
Authors:   , Zhang Yaqi , Woerdeman Hugo J.
Published: August 2023

Zero forcing is a color changing process on the vertices of a graph. The zero forcing number of a graph is the minimum cardinality among the zero forcing sets, which are subsets of the vertices which have the property that as a starting set it will color the whole graph. A motivation for studying zero forcing is the study of minimum rank and maximum nullity of matrices with a given sparsity pattern. The zero forcing number provides an upper bound for the maximum nullity of a matrix whose off-diagonal non-zero entries are described by the graph. The study of zero forcing includes several questions regarding, for instance, the propagation time (pt₊(G)) of a graph G and a maximum failed zero forcing set. In this thesis, the tight upper bound pt₊(G) [less than or equal to] [rounded up][[[absolute value][V(G)] - Z₊(G)]/2] is established for the positive semidefinite propagation time of a graph G in terms of its positive semidefinite zero forcing number Z₊(G). To prove this bound, two methods of transforming one positive semidefinite zero forcing set into another and algorithms implementing these methods are presented. Consequences of the bound, including a tight Nordhaus-Gaddum sum upper bound on the positive semidefinite propagation time, are established. In order to study the maximum failed zero forcing set, we introduce a definition for the spark of a graph which is closely related to the notion of a fort, and we build a connection from the spark of the graph to the maximum failed zero forcing set size. In addition, we consider the full spark scenario for graphs. We also study how these quantities change when we replace a graph by its shadow graph, which is obtained from a graph G by adding for each vertex v of G a new vertex u, called the shadow vertex of v, and joining u to the neighbors of v in G. As the maximum nullity of a matrix is the maximum geometric multiplicity of zero as an eigenvalue, it is also natural to study the appearing multiplicities among the eigenvalues of the matrices. In the final chapter, we establish a connection between the number of distinct eigenvalues from level symmetric trees to that of a path, and present a conjecture for the minimal total eigenvalue multiplicities for a path along with some evidence in support of this conjecture.
WoC-Bots

Published: August 2023

This dissertation presents Wisdom-of-Crowds-Bots (WoC-Bots), biologically-inspired, simple, and modular agents which work together in a multi-agent environment to collectively make binary predictions. Building on the theoretical underpinnings of Wisdom of Crowds, WoC-Bots represent a knowledge-diverse crowd where each agent is trained on a subset of available information. A honeybee-derived swarm aggregation mechanism was developed to elicit a collective prediction with an associated confidence score. Due to the multi-agent architecture, WoC-Bots can be distributed across multiple compute nodes, reducing training and inference time. Importantly, this architecture demonstrates significant key advantages over traditional classification methods while maintaining comparable predictive performance. Specifically, new and previously unknown input features can be included in an existing classification problem without retraining existing agents. New input features, combined with existing features, are encapsulated into newly generated agents before agents are injected into an existing classification task. Further development led to a "meta- swarm", where an external prediction is used as the core belief of an agent, replacing a simple multi-layer perceptron network. The external prediction requires zero knowledge of source data, maintaining the localization and privacy of the data used to generate the prediction, enabling collaboration between institutions unable to share their data externally.
