Este artigo discute algumas relações entre indisciplina, incivilidade e cidadania na escola. Inicialmente abordamos algumas questões sobre disciplina e educação, e exploramos a noção de indisciplina como um modo de ruptura nas relações pedagógicas. A seguir discutimos a noção de incivilidade, recorrendo ao pensamento do sociólogo francês Bernard Charlot. Buscamos traçar uma relação entre incivilidade e indisciplina na escola. Também abordamos o conceito de cidadania, explorando alguns dos seus significados no cenário educacional. Ao final, analisamos a possibilidade das incivilidades estarem a comunicar algo ao projeto educacional, civilizatório das escolas, e recorremos à noção de reconhecimento, a qual nos parece promissora para avançar as noções de cidadania, respeito, civilidade, educação e disciplina nas escolas.

Este artigo apresenta um estudo sobre o professor interdisciplinar, pensando sua formação a partir de duas perspectivas conceituais complementares sobre o perfil desse professor. Inicialmente são exploradas as contribuições de dois teóricos brasileiros da interdisciplinaridade, onde se resgata de suas obras particularmente as implicações de considerar a interdisciplinaridade enquanto atitude em relação ao conhecimento. A seguir consideramos a perspectiva de um grupo de professores de Educação Básica, também sobre o perfil suposto de um professor interdisciplinar. Ao final, após contrastar e integrar as características associadas ao professor interdisciplinar originadas das fontes indicadas acima, analisamos alguns aspectos da formação dos professores para a interdisciplinaridade.

Purpose
This paper aims to describe an effort to provide for a robust and secure software development paradigm intended to support DevSecOps in a naval aviation enterprise (NAE) software support activity (SSA), with said paradigm supporting strong traceability and provability concerning the SSA's output product, known as an operational flight program (OFP). Through a secure development environment (SDE), each critical software development function performed on said OFP during its development has a corresponding record represented on a blockchain.


Design/methodology/approach
An SDE is implemented as a virtual machine or container incorporating software development tools that are modified to support blockchain transactions. Each critical software development function, e.g. editing, compiling, linking, generates a blockchain transaction message with associated information embedded in the output of a said function that, together, can be used to prove integrity and support traceability. An attestation process is used to provide proof that the toolchain containing SDE is not subject to unauthorized modification at the time said critical function is performed.


Findings
Blockchain methods are shown to be a viable approach for supporting exhaustive traceability and strong provability of development system integrity for mission-critical software produced by an NAE SSA for NAE embedded systems software.


Practical implications
A blockchain-based authentication approach that could be implemented at the OFP point-of-load would provide for fine-grain authentication of all OFP software components, with each component or module having its own proof-of-integrity (including the integrity of the used development tools) over its entire development history.


Originality/value
Many SSAs have established control procedures for development such as check-out/check-in. This does not prove the SSA output software is secure. For one thing, a build system does not necessarily enforce procedures in a way that is determinable from the output. Furthermore, the SSA toolchain itself could be attacked. The approach described in this paper enforces security policy and embeds information into the output of every development function that can be cross-referenced to blockchain transaction records for provability and traceability that only trusted tools, free from unauthorized modifications, are used in software development. A key original concept of this approach is that it treats assigned developer time as a transferable digital currency.

Abstract
Increased levels of extracellular nicotinamide phosphoribosyltransferase (eNAMPT) are increasingly recognized as a highly useful biomarker of inflammatory disease and disease severity. In preclinical animal studies, a monoclonal antibody that neutralizes eNAMPT has been generated to successfully reduce the extent of inflammatory cascade activation. Thus, the rapid detection of eNAMPT concentration in plasma samples at the point of care (POC) would be of great utility in assessing the benefit of administering an anti-eNAMPT therapeutic. To determine the feasibility of this POC test, we conducted a particle immunoagglutination assay on a paper microfluidic platform and quantified its extent with a flow rate measurement in less than 1 min. A smartphone and cloud-based Google Colab were used to analyze the flow rates automatically. A horizontal flow model and an immunoagglutination binding model were evaluated to optimize the detection time, sample dilution, and particle concentration. This assay successfully detected eNAMPT in both human whole blood and plasma samples (diluted to 10 and 1%), with the limit of detection of 1–20 pg/mL (equivalent to 0.1–0.2 ng/mL in undiluted blood and plasma) and a linear range of 5–40 pg/mL. Furthermore, the smartphone POC assay distinguished clinical samples with low, mid, and high eNAMPT concentrations. Together, these results indicate this POC assay, which utilizes low-cost materials, time-effective methods, and a straightforward immunoassay (without surface immobilization), may reliably allow rapid determination of eNAMPT blood/plasma levels to advantage patient stratification in clinical trials and guide ALT-100 mAb therapeutic decision-making.

In Canada, the prevalence of food insecurity is high among low-income households, particularly recent refugees. We evaluated the prevalence of food security among recent Syrian refugees and the associated factors in two Canadian cities, Toronto and Saskatoon. We collected data using the Household Food ‎Security Model, sociodemographic and socioeconomic questionnaires from 151 families. 84% of the Syrian households were food insecure, with no significant difference in prevalence between Saskatoon and Toronto. The risk of food insecurity was four ‎times higher for households with the annual income below $40,000. Households with educated woman (high school or higher) had four times higher risk of household food insecurity compared to families with less-educated women. ‎Our findings indicate the high prevalence of food insecurity among recently resettled Syrian refugees in Canada. Higher-income directly associated with food security. The inverse association between education and food security in households with highly educated women warrants further investigation.
