    Abstract: This paper aims to examine whether there are morally defensible reasons for using or operating websites (called ‘booters’) that offer distributed denial-of-service (DDoS) attacks on a specified target to users for a price. Booters have been linked to some of the most powerful DDoS attacks in recent years. Design/methodology/approach The authors identify the various parties associated with booter websites and the means through which booters operate. Then, the authors present and evaluate the two arguments that they claim may be used to justify operating and using booters: that they are a useful tool for testing the ability of networks and servers to handle heavy traffic, and that they may be used to perform DDoS attacks as a form of civil disobedience on the internet. Findings The authors argue that the characteristics of existing booters disqualify them from being morally justified as network stress testing tools or as a means of performing civil disobedience. The use of botnets that include systems without the permission of their owners undermines the legitimacy of both justifications. While a booter that does not use any third-party systems without permission might in principle be justified under certain conditions, the authors argue that it is unlikely that any existing booters meet these requirements. Practical/implications Law enforcement agencies may use the arguments presented here to justify shutting down the operation of booters, and so reduce the number of DDoS attacks on the internet. Originality/value The value of this work is in critically examining the potential justifications for using and operating booter websites and in further exploring the ethical aspects of using DDoS attacks as a form of civil disobedience.

    Abstract: Recent advances in artificial intelligence (AI) offer an opportunity for the adoption of self-driving networks. However, network operators or home-network users still do not have the right tools to exploit these new advancements in AI, since they have to rely on low-level languages to specify network policies. Intent-based networking (IBN) allows operators to specify high-level policies that dictate how the network should behave without worrying how they are translated into configuration commands in the network devices. However, the existing research proposals for IBN fail to exploit the knowledge and feedback from the network operator to validate or improve the translation of intents. In this paper, we introduce a novel intent-refinement process that uses machine learning and feedback from the operator to translate the operator's utterances into network configurations. Our refinement process uses a sequence-to-sequence learning model to extract intents from natural language and the feedback from the operator to improve learning. The key insight of our process is an intermediate representation that resembles natural language that is suitable to collect feedback from the operator but is structured enough to facilitate precise translations. Our prototype interacts with a network operator using natural language and translates the operator input to the intermediate representation before translating to SDN rules. Our experimental results show that our process achieves a correlation coefficient squared ( i.e., R-squared) of 0.99 for a dataset with 5000 entries and the operator feedback significantly improves the accuracy of our model.

    Abstract: Avaliar a relação entre o tabagismo e os fatores comportamentais e sociodemográficos entre acadêmicos da área de saúde da Universidade Estadual da Paraíba (UEPB). Foi realizado um estudo transversal analítico, no qual foi obtida uma amostra representativa de cada curso (Odontologia, Enfermagem, Psicologia, Farmácia, Fisioterapia e Educação Física). Foram entrevistados 492 alunos por meio de formulário estruturado. Os testes estatísticos utilizados foram Qui-quadrado e o Exato de Fisher (significância de 5%). A prevalência de tabagismo foi de 5,7% e o estresse foi a principal razão para o início do hábito (36,8%). Na análise multivariada por regressão logística as variáveis, sexo, prática de religião, período cursado e consumo etílico apresentaram-se associadas ao hábito de fumar (p 〈 0,05). Apesar de estudos relatarem uma forte relação entre estudantes universitários e fumo, a prevalência de tabagismo foi baixa. A maioria das variáveis estudadas demonstrou associação com o hábito de fumar. Sendo o fumo e o álcool as duas maiores dependências humanas, este estudo sugere uma relação bidirecional entre estas variáveis.

    Abstract: Home telemonitoring is a promising approach to optimizing outcomes for patients with Type 2 Diabetes; however, this care strategy has not been adapted for use with understudied and underserved Hispanic/Latinos (H/L) patients with Type 2 Diabetes. Methods A formative, Community-Based Participatory Research approach was used to adapt a home telemonitoring intervention to facilitate acceptability and feasibility for vulnerable H/L patients. Utilizing the ADAPT-ITT framework, key stakeholders were engaged over an 8-month iterative process using a combination of strategies, including focus groups and structured interviews. Nine Community Advisory Board, Patient Advisory, and Provider Panel Committee focus group discussions were conducted, in English and Spanish, to garner stakeholder input before intervention implementation. Focus groups and structured interviews were also conducted with 12 patients enrolled in a 1-month pilot study, to obtain feedback from patients in the home to further adapt the intervention. Focus groups and structured interviews were approximately 2 hours and 30 min, respectively. All focus groups and structured interviews were audio-recorded and professionally transcribed. Structural coding was used to mark responses to topical questions in the moderator and interview guides. Results Two major themes emerged from qualitative analyses of Community Advisory Board/subcommittee focus group data. The first major theme involved intervention components to maximize acceptance/usability. Subthemes included tablet screens (e.g., privacy/identity concerns; enlarging font sizes; lighter tablet to facilitate portability); cultural incongruence (e.g., language translation/literacy, foods, actors “who look like me”); nursing staff (e.g., ensuring accessibility; appointment flexibility); and, educational videos (e.g., the importance of information repetition). A second major theme involved suggested changes to the randomized control trial study structure to maximize participation, including a major restructuring of the consenting process and changes designed to optimize recruitment strategies. Themes from pilot participant focus group/structured interviews were similar to those of the Community Advisory Board such as the need to address and simplify a burdensome consenting process, the importance of assuring privacy, and an accessible, culturally congruent nurse. Conclusions These findings identify important adaptation recommendations from the stakeholder and potential user perspective that should be considered when implementing home telemonitoring for underserved patients with Type 2 Diabetes.

    Abstract: RESUMO Objetivo: Verificar a prevalência e a associação da ansiedade dos pais e filhos entre as variáveis socioeconômicas frente ao comportamento da criança durante o atendimento odontológico. Métodos: Este estudo foi caracterizado como quantitativo, observacional, transversal e descritivo. Para a coleta de dados, utilizou-se um questionário sobre dados sociodemográficos e experiência dentária, Escalas de Teste de Imagem de Venham, Escalas de Ansiedade Odontológica de Corah e Escala de Ansiedade de Frankl. Os dados foram analisados utilizando estatística descritiva e inferencial (Qui-quadrado e Teste exato de Fisher), α=0.05. Resultados: A maioria das crianças pertencia à faixa etária de 7 a 9 anos, 57,9%. Destas, 72,6% foram submetidos a procedimentos invasivos. A prevalência de ansiedade das crianças foi de 43,2% (n=41). Quanto aos pais/responsáveis, a prevalência de ansiedade foi de 88,4% (n=84). Foi verificada associação significativa entre experiência da consulta e ansiedade da criança (p= 0,050) utilizando a escala VTP. E foi verificada associação significativa entre a ansiedade e o tipo de procedimento (p= 0,017) e a experiência da criança (p=0,000) utilizando a escala de Frankl. Conclusão: Não houve associação entre ansiedade e as variáveis socioeconômicas. Nas variáveis relacionadas as experiências odontológicas, foi verificada associação significativa entre a experiência da consulta e a ansiedade da criança utilizando a escala VTP. Na escala de Frankl foi observada associação entre ansiedade e o tipo de procedimento, e experiência da consulta.

    Abstract: Abstract. The QA4ECV (Quality Assurance for Essential Climate Variables) version 1.1 stratospheric and tropospheric NO2 vertical column density (VCD) climate data records (CDRs) from the OMI (Ozone Monitoring Instrument) satellite sensor are validated using NDACC (Network for the Detection of Atmospheric Composition Change) zenith-scattered light differential optical absorption spectroscopy (ZSL-DOAS) and multi-axis DOAS (MAX-DOAS) data as a reference. The QA4ECV OMI stratospheric VCDs have a small bias of ∼0.2 Pmolec.cm-2 (5 %–10 %) and a dispersion of 0.2 to 1 Pmolec.cm-2 with respect to the ZSL-DOAS measurements. QA4ECV tropospheric VCD observations from OMI are restricted to near-cloud-free scenes, leading to a negative sampling bias (with respect to the unrestricted scene ensemble) of a few peta molecules per square centimetre (Pmolec.cm-2) up to −10 Pmolec.cm-2 (−40 %) in one extreme high-pollution case. The QA4ECV OMI tropospheric VCD has a negative bias with respect to the MAX-DOAS data (−1 to −4 Pmolec.cm-2), which is a feature also found for the OMI OMNO2 standard data product. The tropospheric VCD discrepancies between satellite measurements and ground-based data greatly exceed the combined measurement uncertainties. Depending on the site, part of the discrepancy can be attributed to a combination of comparison errors (notably horizontal smoothing difference error), measurement/retrieval errors related to clouds and aerosols, and the difference in vertical smoothing and a priori profile assumptions.

    Abstract: During the early stages of the COVID-19 pandemic, nationwide lockdowns caused disruption in the diets, physical activities, and lifestyles of patients with type 2 diabetes. Previous reports on the possible association between race/ethnicity, COVID-19, and mortality have shown that Hispanic/Latino patients with type 2 diabetes who are socioeconomically disadvantaged are disproportionately affected by this novel virus. The aim of this study was to explore stressors associated with changes in diabetes self-management behaviors. Our goal was to highlight the health disparities in these vulnerable racial/ethnic minority communities and underscore the need for effective interventions. Methods and participants Participants were enrolled in part of a larger randomized controlled trial to compare diabetes telehealth management (DTM) with comprehensive outpatient management (COM) in terms of critical patient-centered outcomes among Hispanic/Latino patients with type 2 diabetes. We conducted a thematic analysis using patient notes collected from two research nurses between March 2020 and March 2021. Two authors read through the transcripts independently to identify overarching themes. Once the themes had been identified, both authors convened to compare themes and ensure that similar themes were identified within the transcripts. Any discrepancies were discussed by the larger study team until a consensus was reached. Results Six themes emerged, each of which can be categorized as either a source or an outcome of stress. Sources of stress associated with the COVID-19 pandemic were (1) fear of contracting COVID-19, (2) disruptions from lockdowns, and (3) financial stressors (e.g., loss of income). Outcomes of COVID-19 stressors were (1) reduced diabetes management (e.g., reduced diabetes monitoring and physical activity), (2) suboptimal mental health outcomes (e.g., anxiety and depression), and (3) outcomes of financial stressors. Conclusion The findings indicated that underserved Hispanic/Latino patients with type 2 diabetes encountered a number of stressors that led to the deterioration of diabetes self-management behaviors during the pandemic.
