Retention and Persistence in University Continuing Education Programs at the University of Manitoba—A Case Study
Authors: Sloane-Seale Atlanta
Published: July 2024

This case study of university continuing education (UCE) students at the University of Manitoba (UM) explored the retention and persistence of adult learners in non-credit certificate programs. Data from telephone interviews of those who had not taken a course in the past two years were used. The purposes of the study were to understand why adult learners participate in and drop out from UCE non-credit certificates; understand their goals, intentions, barriers to participation, and retention; and identify effective recruitment and retention strategies. The findings suggest that understanding the nature of these adult learners is critical for retention and persistence; that they have dependent children and are highly motivated and goal-oriented; and that they work full time and “stop out” from their programs because of work–life balance issues, including situational, dispositional, institutional, and systemic barriers. Further, understanding the nature of their classroom experience is critical for retention and persistence, institutional sustainability, and program improvements.

Published: July 2024

This article discusses the educational life stories of three first-generation university students’ as relates to cultural capital. Using Pierre Bourdieu’s theory of cultural capital as a framework, the research sought to examine how the participants experience cultural capital that is typically privileged in education. It explores how the interactions between possessed and privileged forms of capital affect educational experiences and perceptions. A focus on each participant’s experiences with culture, capital, and education revealed themes corresponding to navigating, utilizing, and confronting familial, institutional, economic, social and represented forms of cultural capital. Understanding first-generation students’ educational life stories sheds light on the complex challenges facing those who confront and deal with privileged culture in the education system. This article adds to the growing body of research about cultural capital as relates to first-generation university students and argues for a critical exploration of education through individual experiences.
The psychodrama without the active use of the physical body: Psychoanalytical challenges at the time of COVID-19
Authors: Biolcati Roberta
Published: July 2024

The coronavirus (COVID-19) pandemic has forced the implementation of online psychotherapy (OP) practice. A literature search has revealed the paucity of studies on the psychoanalytic approach to OP and the lack of clinical experiences of analytic psychodrama (AP) via the Internet. The present work aims to discuss the difficulties encountered and the resources offered by a brief account of group psychotherapy through the technique of AP realized via videoconference. With some adjustments, the online roleplaying game was feasible through the two-dimensional space of the screen and allowed the patient to change his/her point of view, even if the AP technique struggled in the absence of the physical body in action. Performing psychodrama without the active use of the physical body, from an adaptation initially forced by the emergency situation, has proven to be an interesting psychoanalytical challenge worthy of deeper investigation and pursuit in the future.
A mentalizing approach to treating children with attachment trauma in group - Experiences from two cases
Authors: Nasu Rie , Kimura Yoshinari
Published: July 2024

The purpose of the study was to discuss the methodology and techniques from the perspective of the mentalizing approach and to examine significant aspects of the treatment processes of children with attachment trauma in group therapy. Two cases of children with attachment trauma were presented and discussed. It was found that in group therapy, the ability in children to form significant relationships was activated and developed. Attachment trauma took shape as a problem in relation with therapist and/or group members. Therapists tried to understand them through a mentalizing stance and tried to help develop a secure attachment. Gradually, based on the relationship with the therapists as a secure base, children began to approach other members, developing chumship with them, and relational bonds were strengthened, where traumatic events were described and accepted, and dissociated parts were integrated in them. Interventions for uncooperative parents were also recognized as an important key.

Published: July 2024

This study evaluates the quality assessment of developed cordial beverages. Four various formulations of cordial drink were. The first juice combines tamarind lace acid with sugar in the formulation process. In the second variant, the juice is mixed with sugar and supplemented with salt. The third formulation incorporates tamarind lace acid juice mixed with sugar and enriched with pandan leaves. Lastly, the fourth variant combines juice, sugar, and salt and adds two pandan leaves. Each formulation of tamarind lace acid-based cordial drink undergoes comprehensive evaluation, encompassing the analysis of pH, Tss, Color, and organoleptic attributes. The analysis outcomes for the cordial drink formulations revealed that cordials with the addition of salt were well-received, as indicated by the research results. The results of this study on the quality of tamarind-based soft drinks (Carissa carandas L.) with the addition of sugar, salt, pandan leaves with the treatment of Cordial Basic, Cordial Salt, Cordial Pandan, Cordial Salt + Pandan have pH (2. 09; 1.74; 1.89; 1.66), TSS (67.38; 70.23; 67.65; 54.05) Colour (25.70; 29.69; 29.09; 26.17), a* (4.04; 3.42; 2.82; 3.77), b* (0.45; 0.49; 0.40; 0.65). In the sensory test of taste and overall acceptance, drinks with the Quality of Tamarind Fruit Juice with the Addition of Salt have the best results because they have a level of sweetness with the addition of salt in the manufacture of tamarind-based drinks significantly affects the parameters of Taste, Mounth Feeling and Odour.

Authors: Wirandi Putra Mahirza , Nurhajijah Nurhajijah , Hashim Nur Aida
Published: July 2024

The study of the effectiveness of several active ingredients of chemical insecticides in controlling insects in sweet potato plants (Ipomoea batatas L.) was carried out at the UMT Bukit Kor Agricultural Complex, Marang Trengganu Malaysia from 14 September to 21, 2023—research methods. The design used a randomised group design (RAL) with three treatments and three repeats, namely T0 Control, T1 Sulfoxaflor 1.5 gr/ 2 litres of water, T2 Buprozen + Cartap Hydrochloride 2 g / 2 litres of water. The observation of mortality percentage was carried out until the seventh day, and the result was calculated using the formula M a/b x 100 %. The Brine Shrimp Lethality Test (BSLT) is used to observe compounds' toxicity. The result obtained is calculated as the LC50 (lethal concentration) value. The results showed that the toxicity of both insecticide active ingredients used was considered very effective for controlling target insects of the Hemiptera order. The active ingredient Sulfoxaflor obtained an insect mortality percentage of the order Hemiptera by 100%, and the active ingredients Buprozen and Cartap Hydrochloride obtained 100%. However, non-target organisms such as the Araneae order, a natural enemy, namely Oxyopes javanus, are also affected by 100% toxicity of the two active ingredients, from calculating the LC50 value from probit analysis after obtaining results. The LC50 value obtained is 47.11 ppm. The LC50 value of these two insecticides has a toxic potential because the value is below 1000 ppm.

Continuity cholecystitis secondary to peptic ulcer perforation: an unusual presentation: Case report
Authors: Brambila Jorge Pareja Helen , Tavares Borges Junior Zimar , De Souza Camargo Matheus
Published: July 2024

The diagnosis of acute cholecystitis is based on the signs and symptoms presented by the patient and also on imaging tests. As the clinical picture can have different presentations depending on the patient's health conditions and age, sometimes confirmation is totally dependent on radiology reports, which in this case are examiner-dependent, which is inherently prone to human error and can lead to incorrect diagnoses. We analyzed the history contained in the medical records of a patient who was admitted to the emergency department complaining of abdominal pain and a letter written by her doctor, recommending emergency surgery to treat acute cholecystitis. New tests were carried out, which ended up ruling out the previous diagnosis, and the surgical procedure revealed a perforated peptic ulcer, which led to cholecystitis, and, overlapping, both diagnoses made the case unusual and atypical in presentation.
Spontaneous elimination of gossypiboma: A case report
Authors: Assunção M. Silveira Gabriela , Russo Rodrigues Beatriz , Fernando e Oliveira Paulo
Published: July 2024

Introduction: The term gossypiboma refers to surgical items of textile matrix inadvertently left inside cavities after closure of the surgical wound. The unrecognized presence of a foreign body of any kind in the abdominal cavity after an operation is a situation rarely reported in the medical literature and surrounded by a potential for serious complications, which can evolve into a fatality. This article is an observational and descriptive case report. The information was collected by reviewing the medical records and photographic records of the surgical procedures the patient underwent. It aims to present a case of spontaneous elimination of gossypoma in a patient who had undergone a previous caesarean section. Report: Patient R.T.T.S, 17 years old, female, previously healthy, with sporadic diffuse abdominal pain for 10 months after caesarean section, with progressive worsening. One week ago, she had a significant worsening of the pain associated with constipation, difficulty in evacuating and, one day ago, anal elimination of contents similar to vegetable loofah (SIC). Physical examination revealed a slight bulge in the hypogastric region and rectal elimination of a foreign body. Discussion: Imaging methods are important allies in identifying this type of problem. The surgical approach adopted will depend on the clinical and radiological presentation of the gossypiboma. In the case reported here, we opted for rectal removal of the foreign body while preserving the integrity of the abdominal cavity, as the patient had no symptoms of abscess or fistulae. She evolved in the post-operative period in good clinical condition. Cases like this are increasingly reinforcing the need to adopt and strictly comply with checklists prior to surgery and at the end of surgery. In order to provide safe surgeries with excellence for patients in any institution in the country.
“Perfect presence space”: Theoretical and practical aspects of the concept
Authors: Frankiv Roman
Published: July 2024

Due to the potential for creating immersive spaces in which the “function” of attracting and retaining attention replaces traditional calculations of climatic conditions, safety, gravity, etc., there is a need for terms for broader generalisation and evaluation. The purpose was to argue the expediency of using the term “perfect presence space”, as one that can collectively determine the value level of various design attempts to spatially express media and communicative realities, including comparing them with the experience of traditional architectural styles. The main method is a comparative analysis of specially selected architectural phenomena. On the basis of a brief historical retrospective, the tendency to gradually replace the functionalist “rational” substantiation of elements of space (associated with everyday life) with the attraction “irrational” (associated with non-ordinary life) is shown; the presence of experience in the materialisation of non-ordinary states in the architecture of different eras and purposes. Further, a review of several content frameworks that led architectural design to the interpretation of an exceptional or perfect presence is carried out, such as urban-social utopias of “ideal cities”, objects of religious pilgrimages and narrative stories, places of exceptional aesthetic qualities of the natural environment outlined by “paradise” metaphors, and representative and solemn squares of capital cities. The potential of the term “perfect presence space” is shown, which allows effectively operating with the motivational foundations of creating a modern space, which are based on attracting and retaining attention and stay; it provides a conceptual basis for evaluating offers of visual and spatial stay (non-virtual and virtual). The assumption is made about the mechanism of “idealisation” of presence, which is developed through the interaction of three components: person – attention – stay. The practical significance of the study is the opportunity, based on succinct, meaningfully clear and universal terms, to facilitate the perception of the architectural environment and improve the involvement of a wider range of stakeholders and participation groups in the study of design
Manufacture and regulation of cell, tissue and gene therapy products: global perspectives, challenges and next steps
Authors: Sia Chong Hock , Koh Christine , Chan Lai Wah
Published: July 2024

Cell, tissue and gene therapy products (CTGTPs) are therapeutic products intended for use in humans for prophylactic, diagnostic, curative, palliative or diagnostic purposes. Generally, they are breakthrough therapies with immense potential in treating diseases with no cure or rare diseases with high treatment burdens. Thus far, the number of approved cell, tissue and gene therapies globally are few and far between, with some approved products being recalled due to safety and efficacy issues. This situation highlights the need to rectify the challenges that are present in the manufacturing and regulation of these medicines. This article presents an overview of how CTGTPs work using examples of existing approved products across different product categories, as their mechanisms of action and characteristics contribute to manufacturing challenges. The differences between CTGTPs and conventional biologicals will be highlighted to understand the need for different regulatory frameworks to be designed. Additionally, these frameworks by the major regulatory authorities and international organizations will be analysed to elucidate whether CTGTPs are regulated to different extents across countries. Challenges faced in the manufacturing and regulation of CTGTPs include quality assurance issues, lack of expertise and limitations in technology. Potential solutions include implementing a tighter regulatory framework, fostering the international harmonization of regulations, increasing outsourcing to meet good manufacturing practice (GMP) guidelines, and incorporating automation into manufacturing processes to improve quality control to address the challenges encountered.

Published: July 2024

This study focuses on the collection of marine samples and the subsequent screening of xanthone compounds from the marine fungi Aspergillus sydowii. Marine fungi, especially those from the genus Aspergillus, are known for producing a wide array of bioactive compounds with significant therapeutic potential. The primary objective was to isolate and identify fungal strains capable of producing xanthones and evaluate their bioactive properties. Samples were collected from various marine environments, including coastal waters and deep-sea sediments, and preserved under sterile conditions. Fungal isolates were cultured, and xanthones were extracted and purified using chromatographic techniques. The purified compounds were identified using spectroscopic methods and tested for their antimicrobial and antioxidant activities. The results revealed that the xanthones exhibited potent antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans, as well as strong antioxidant properties. These findings highlight the potential of marine-derived xanthones for pharmaceutical applications, including the development of new antibiotics and antioxidant therapies. The study underscores the importance of marine fungi in the discovery of novel bioactive compounds and their potential applications in biotechnology and industry.

Published: July 2024

Variation in the diversity and abundance of associated macro fauna of two commonly encountered seaweed species viz., Sargassum sp. and Amphiroa sp. were assessed seasonally. 100 grams wet weights per seaweed species in replicate were sampled from the rocky shore tide pools of Sindhudurg district of Maharashtra, India in 2021.
14 groups of macro fauna were found in association with Sargassum sp. and 18 groups with Amphiroa sp. In Sargassum sp. the highest abundance (individuals/100 grams seaweed) was recorded during Post-monsoon (116.86 ±188.24 SD), Pre-monsoon (339.65 ±347.15 SD) and Monsoon (127.14 ±67.14 SD) by Amphipoda respectively; while in Amphiroa sp. during Post-monsoon Foraminifera (740.74 ±1047.57 SD), Pre-monsoon H. Copepoda (87.80 ±3.54 SD) and Monsoon Bivalvia (55.69 ±33.19 SD). Highest biomass (mg/100 grams seaweed) in Sargassum sp. during Post-monsoon (241.51 ±429.26 SD) and Monsoon (359.76 ±356.90 SD) by Gastropoda respectively, during Pre-monsoon Amphipoda (214.55 ±191.77 SD); while in Amphiroa sp. during Post-monsoon Polychaeta (752.50 ±680.09 SD), during Pre-monsoon Gastropoda (452.68 ±457.97 SD) and during Monsoon Bivalvia (662.85 ±221.60 SD).
Diversity indices in both the seaweeds during Monsoon, showed high evenness and Shannon diversity; higher dominance is seen during Pre-monsoon in Sargassum sp. and during Post-monsoon in Amphiroa sp.
ANOVA and Kriskal-Wallis test showed significant variance in the abundance of Turbellaria, Ophiuroidea, Amphipoda, Isopoda, Decapoda, Tanaidacea, Copepoda, Bivalvia, Cnidaria, and Eggs. Spearman’s correlation test showed significant correlations between the environmental parameters that are pH, dissolved oxygen, conductivity, total dissolved solids, salinity, turbidity, water and air temperature and tide pool depth with the macro faunal abundance of Copepoda, Turbellaria, Ophiuroidea, Tanaidacea, Isopoda and Decapoda.
Majority of macro fauna stays in association with seaweeds, as it provides food and shelter to them. Since Sargassum sp. and Amphiroa sp. were significantly available, it was selected for sampling. Study reveals both the seaweeds supports diversity of macro fauna which vary seasonally.

4 - Influence of Socioeconomic Activities on House Form and Settlement Patterns Among the Tiv People of Central Nigeria
Authors: Terna Aule Thomas , Roshida Binti Abdul Majid  , Mahmud Bin Mohd Jusan
Published: July 2024

The formation of housing and settlement patterns, such as shape, space enclosure and organisation, are influenced by physical, social and economic factors. However, Rapaport found that sociocultural factors are the primary determinants of built form. This view has been challenged, justifying a replication of the study in other built environments. This study explores the influence of the socioeconomic occupation of the Tiv people in Nigeria on their housing and settlement patterns. The means-end chain qualitative enquiry was applied during interviews with twenty-four participants to determine the inherent socioeconomic values connecting their occupation to settlement pattern. Their settlements were found to be dispersed, with aggregated joint compounds, creating sufficient space for farming. However, the pattern of dispersion of settlements poses security risks. Therefore, transformative efforts are required to aggregate the settlements to make more land available for mechanised agriculture and to enhance people’s safety. More studies are required to reveal the sociocultural values of Nigerian Indigenous housing for sustainable development of their built environments and way of life.

Published: July 2024

The existence of media convergence is an effort to adapt radio to the digital era. Although many people think that radio will no longer survive in the midst of technological and information developments, in fact, many radios still survive and have loyal listeners and partnerships to use radio advertising services. This form of research aims to find out the application of media convergence carried out by Shelter 95.6 FM Radio's public relations to maintain its existence amid the presence of various new media as competitors and the development of technology and information. This research uses qualitative research methods and data collection by interviewing 2 sources with public relations and broadcasters and descriptive observations and data collection techniques through previous literature studies, strengthened by the Media Convergence theory developed by Henry Jenkins through the 3C approach (computing, communication & content). Some of the applications made by Shelter FM to compete with other media are the application of computing convergence media Shelter FM has adapted by broadcasting Shelter FM outside with only a laptop, microphone, and audio mixer and the application of communication convergence media live radio broadcasts and also streaming Shelter FM radio in the Shelter FM application and content convergence media by delivering information and broadcasting using digital technology, namely social media to expand networks and audiences.
Hospitalists’ perception of their communication with primary care providers – survey results from six hospitals in Central Switzerland
Authors: Käufeler Manuela , Beeler Patrick E. , Müller Lena S. , Gemperli Armin , Merlo Christoph , Hug Balthasar L.
Published: July 2024

OBJECTIVES: Due to the increasing complexity of the healthcare system, effective communication and data exchange between hospitalists (in-hospital physicians) and primary care physicians (PCPs) is both central and challenging. In Switzerland, little is known about hospitalists’ perception of their communication with PCPs. The primary objective was to assess hospitalists’ satisfaction with their communication with PCPs. Secondary objectives addressed all information about the referral process and communication with PCPs during and after the hospital encounter. Lastly, the results of a previous survey among PCPs were juxtaposed to compare their responses to similar questions.
METHODS: This study surveyed hospitalists in six hospitals in the Central Switzerland region. The survey was sent via email to hospitalists from November 2021 to February 2022. The questionnaire contained 17 questions with single- and multiple-choice answers and the option of free-text entry. Exploratory multivariable logistic regression was used to analyse independent associations.
RESULTS: In total, 276 of 1134 hospitalists responded (response rate 24.3%): (1) the majority of hospitalists are satisfied with the general communication (n = 162, 58.7%) as well as with referral letters (n = 145, 52.5%), (2) preferred information channels for referral letters are email (n = 212, 76.8%) and electronic portals (n = 181, 65.5%), (3) the three most important items of information in referrals are: medication list, diagnoses and reason for referral. In multivariable regression, compared to other clinicians, internists independently favoured informing PCPs of emergency admissions of their patients in a timely manner (OR 2.04; 95%CI 1.21–3.49). Comparing responses from PCPs (n = 109), the most prominent discrepancy was that 67% (n = 184) of hospitalists claimed to “always” inform after an encounter, whereas only 7% (n = 8) of PCPs agreed.
CONCLUSION: Most hospitalists are satisfied with the communication with PCPs and prefer electronic communication channels. Room for improvement was found around timely transmission of patient information before and after hospital encounters.

Efficient online tree, rule-based, and distance-based algorithms
Authors: Mastelini Saulo Martiello , Carvalho André Carlos Ponce de Leon Ferreira de
Published: July 2024

The fast development of technology resulted in the constant production of data in different forms and from different sources. Contrary to what was observed in the first machine learning (ML) research works, there might be too much data to handle with traditional algorithms. Changes in the underlying data distributions might also render traditional ML solutions useless in real-world applications. Online ML (OML) aims to create solutions able to process data incrementally, with limited computation resource usage, and to deal with time-changing data distributions. Unfortunately, we have seen a recent growing trend in creating OML algorithms that solely focus on predictive performance and overlook computational costs. In regression tasks, the problem is even more pronounced when considering some of the most popular OML solutions: decision trees, decision rules, and ensembles of these models. In this thesis, we created improved and efficient OML algorithms from the mentioned algorithmic families by focusing on decreasing time and memory costs while keeping competitive predictive performance. Our proposals are either novel standalone OML algorithms or additions that can be paired with any existing tree or decision rule regressors.
On the Role of Semantic Word Clusters — CluWords — in Natural Language Processing (NLP) Tasks
Authors: Viegas Felipe , Rocha Leonardo , Gonçalves Marcos André
Published: July 2024

The ability to represent data in meaningful and tractable ways is crucial for Natural Language Processing (NLP) applications. This Ph.D. dissertation focused on proposing, designing and evaluating a novel textual document representation that exploits the “best of two worlds”: efficient and effective frequentist information (TFIDF representations) with semantic information derived from word embedding representations. In more details, our proposal – called CluWords – groups syntactically and semantically related words into clusters and applies domain-specific and application-oriented filtering and weighting schemes over them to build powerful document representations especially tuned for the task in hand. We apply our novel Cluword concept to four NLP applications: topic modeling, hierarchical topic modeling, sentiment lexicon building and sentiment analysis. Some of the novel contributions of this dissertation include: (i) the introduction of a new data representation composed of three general steps (clustering, filtering, and weighting). These steps are specially designed to overcome task-specific challenges related to noise and lack of information; (ii) the design of CluWords’ components capable of improving the effectiveness of Topic Modeling, Hierarchical Topic Modeling and Sentiment Analysis applications; (iii) the proposal of two new topic quality metrics to assess the topical quality of the hierarchical structures. Our extensive experimentation demonstrates that CluWords produce the current state-of-the-art topic modeling and hierarchical topic modeling. For sentiment analysis, our experiments show that CluWords filtering and weighting can mitigate semantic noise, surpassing powerful Transformer architectures in the task. All code and datasets produced in this dissertation are available for replication. Our results were published in some of the most important conferences in journals of the field, as detailed in this document. Our work was supported by two Google Research Awards.
Compromissos arbitrários entre custo e probabilidade à meta e algoritmo de busca heurística em planejamento probabilístico sob o critério GUBS
Authors: Crispino Gabriel Nunes , Freire Valdinei , Delgado Karina Valdivia
Published: July 2024

Processos de Decisão Markovianos de Caminho Estocástico mais Curto (SSP-MDPs) são utilizados para modelar problemas de decisões sequenciais probabilísticas em que o objetivo é minimizar o custo acumulado esperado para a meta. No entanto, na presença de estados a partir dos quais não se pode alcançar a meta (dead ends), esse critério pode deixar de ser bem-definido. GUBS, um critério baseado em Teoria da Utilidade Esperada que realiza compromissos entre custos e probabilidade à meta, foi proposto para resolver esses problemas. A dissertação de mestrado tem como contribuições uma comparação entre o GUBS e outros critérios para resolver SSP-MDPs na presença de dead ends, e introduz definições e resultados teóricos que mostram que o GUBS, ao contrário desses outros critérios, possibilita a realização de compromissos entre custos acumulados sobre perdas em probabilidade à meta, e também garante compromissos arbitrários que podem ser configurados a partir dos seus parâmetros sem conhecimento prévio do problema a ser resolvido. Além disso, o presente trabalho introduz o eGUBS-AO*, um algoritmo ótimo de busca heurística para resolver o critério eGUBS. Como subprodutos da dissertação de mestrado, também foram propostos o α-MCMP, um novo critério, e o UCT-GUBS, um algoritmo de Monte Carlo Tree Search para resolver SSPs sob o critério GUBS.

Este trabalho apresenta um novo método para atualizar modelos de detecção de intrusões usando aprendizado de fluxo, reduzindo eventos para atualização e custos computacionais. Instâncias rejeitadas na classificação são armazenadas para atualização incremental, permitindo rotulação automática a partir de repositórios públicos. Experimentos mostraram que a proposta reduz os falsos-positivos em até 12%, rejeitando 8% das instâncias, em uma base de dados de 2.6 TB. A abordagem consome apenas 3,2% do tempo de processamento e 2% de novas instâncias em comparação com técnicas tradicionais.
Near-Bipartiteness on graphs having small dominating sets: Structural characterization and algorithms
Authors: Cruz Maria Luíza López da , Souza Uéverton S. , Bravo Raquel
Published: July 2024

The Near-Bipartiteness problem asks for a partition of the vertex set of a graph G = (V,E) into two subsets S and F, where S forms an independent set and F induces a forest. Despite its NP-completeness, even for graphs with a diameter three, we explore this problem on graphs with a dominating edge or small dominating sets. Our work presents a polynomial-time algorithm for Near-Bipartiteness on graphs with a dominating edge, a particular case of graphs with diameter three. In addition, we prove that Connected Near-Bipartiteness, the variant where the forest must be connected, is NP-complete on the same class. Moreover, we also establish the NP-hardness of Independent Feedback Vertex Set and Acyclic Vertex Cover on this class of graphs. In addition, by extending our approach to graphs with bounded dominating sets, we achieve a huge improvement, obtaining an O(n2 · m)-time algorithm for Near-Bipartiteness on P5-free graphs, improving upon the current state-of-the-art time complexity of O(n16).
Personalized Route Selection Methods in an Urban Computing Scenario
Authors: Brito Matheus , Cerqueira Eduardo , Rosário Denis
Published: July 2024

As urban areas continue to expand, the infrastructural systems within these regions face multifaceted challenges that detrimentally affect inhabitants’ health and quality of life. The advent of smart urban mobility technologies has introduced a persistent surveillance mechanism over the movement patterns of individuals and the ambient environmental conditions, including but not limited to the prevalence of crime, traffic accidents, and levels of air pollution. These technologies significantly contribute to the enhancement of urban transportation systems. In parallel, Location-Based Social Networks (LBSNs) leverage geolocation data derived from users to analyze travel behaviors and recommend alternative transportation options. This research introduces two innovative strategies aimed at selecting routes characterized by lower levels of pollution: the first strategy employs a multimodal transportation integration approach, and the second endorses route selection based on a comprehensive set of personalized criteria. The multimodal transport strategy offers journey options that are both cost-efficient and minimize environmental pollution. Upon assessing all potential routes, the personalized, multi-criteria-based approach demonstrates superior efficacy in route selection compared to methods that rely on a singular criterion within identical scenarios.

Published: July 2024

A hipótese de mercado eficiente classifica os mercados em eficientes, que não são possíveis de prever o preço futuro, e menos eficientes, que é possível prever o preço futuro. Considerando o possível ganho financeiro ao prever o preço futuro de um ativo, diversos estudos utilizam técnicas de Inteligência Artificial para prever movimentos no mercado de ações. Este artigo se propõe a avaliar a eficácia de modelos por Máquinas de Vetores Suporte e Redes Neurais para prever o comportamento de ações brasileiras, utilizando indicadores técnicos. Os resultados indicam acurácias próximas a 50% para ambos os métodos, sugerindo que o mercado é eficiente e questionando a capacidade de previsão para o mesmo.

Published: July 2024

Este artigo apresenta uma revisão bibliográfica sobre o uso de tecnologias digitais na educação para a inclusão de pessoas com Transtorno do Espectro Autista (TEA) na escola. Como metodologia foram realizadas buscas em bases científicas e utilizados critérios para inclusão e exclusão de publicações, com foco em publicações nacionais que abordam o uso das tecnologias digitais para melhorar o processo de aprendizagem dessas pessoas. Foram considerados, ainda, referenciais teóricos da área da saúde, da legislação brasileira e da psicologia da aprendizagem como base. Análises iniciais apontam que a falta de capacitação profissional para o uso dessas tecnologias se coloca entre as principais dificuldades para aplicação da legislação de inclusão em vigor.
