THE CHANGING SECONDARY CURRICULUM IN ENGLAND
No full textThe writer engages with the debate around the balancing act in the development of curricula between knowledge and skills. There is an advocacy of the idea that content should be given greater prominence.The recent developments in the English curriculum are used to illustrate the dichotomy between skills and knowledge. The author argues that this is in fact a false dichotomy and that higher order skills become undermined if they are not developed alongside a significant knowledge base. Writers such as Bloom and Hirsch are deployed to substantiate the presented arguments.A cogent critique is offered to support subject based, knowledge dominant curricula. Evidence is marshalled to imply that many recent moves to develop vocational curricula by emphasising skills has diluted their value and function as a progressional root to further education and employment
Considerações estéticas e políticas na obra de Lima Barreto: a emergência de um contexto biopolítico
No full textThe present work aims to analyze the political and aesthetic relationship in the work of
Lima Barreto, more specifically in the works O cemetery dos Vivos, Diário intimate and
Diário do hospício. To this end, some nuclei are strategically activated to think about
this relationship, such as language, representation, the notion of militant literature,
narrative space and the concept of Biopower and biopolitics developed by Michael
Foucault. Firstly, the methodological form is constructed and how it can play an
important and strategic role in our analysis. The genealogy of powers aims to reflect
on the concept of history, the problem of knowledge and truth. The problematization of
the literary in Lima Barreto's work is perhaps the starting and ending point of this work.
The literary work and criticism produced by the author corroborate a new perspective
on the literary concept. By pointing to a perspective of militant and black literature, the
author constructs a problematization of the conception of Brazilian literature; This
conception that Regina Dalcastagnè demonstrates was never plural, but a
homogeneous conception, converted into a unity that never corresponded with
diversity, difference and plurality. In theory, the conception of literature is linked to a
vision of the world and society. If for Lukács the literature of the second half of the 19th
century and the beginning of the 20th century was essentially bourgeois, Lima
Barreto's literary work and theoretical understanding go in the opposite direction of this
status quo. This, perhaps, is the great difference of Barrete literature. By promoting an
idea of art that is in line with life, with a humanist and alterity purpose. Briefly, the work
points to the idea that in addition to the author contributing to a more real concept of
Brazilian literature, he, through some elements of narrative theory: space, time,
characters, revolutionizes narrative theory in the sense of appropriate this previously
bourgeois space. In this sense, it becomes almost impossible to carry out a critical
analysis of his work and Brazilian literature as a whole, without problematizing the
aesthetic and political relationships involved in literature.O presente trabalho propõe-se a analisar a relação política e estética na obra de Lima
Barreto, mais especificamente nas obras O cemitério dos Vivos(2018), Diário
Íntimo(2018) e Diário do Hospício(2018). Para isso, alguns núcleos são acionados
estrategicamente para pensar essa relação, como a linguagem, a representação, a
noção de literatura militante, o espaço narrativo e os conceitos de biopoder e
biopolítica desenvolvidos por Michael Foucault. Em um primeiro momento, é
construída a forma metodológica, a genealogia dos poderes, que tem por fundamento
desnaturalizar os fenômenos analisados, fazer uma crítica a origem transcendental
dos mesmos e analisar as relações de poder. A genealogia busca identificar os
dispositivos (mecanismos e estratégias) que articulam as relações de poder e saber.
A genealogia dos poderes tem por objetivo refletir sobre o conceito de história, o
problema do saber e da verdade. A problematização do literário na obra de Lima
Barreto, é, talvez, o ponto de saída e de chegada deste trabalho. O fazer literário e as
críticas produzidas pelo autor corroboram para uma nova perspectiva do conceito
literário. Ao apontar para uma perspectiva de literatura militante e negra, o autor
constrói uma problematização da concepção de literatura brasileira; concepção esta
que Regina Dalcastagnè(2012) demonstra que nunca foi plural, mas uma concepção
homogênea, convertida em uma unidade que nunca correspondeu com a diversidade,
diferença e pluralidade. Em tese, a concepção de literatura está ligada a uma visão
de mundo e de sociedade. Se, para Lukács(2009), a Literatura da segunda metade
do século XIX e começo do século XX era essencialmente burguesa, o fazer literário
e o próprio entendimento teórico de Lima Barreto vão na direção oposta desse status
quo. Este, talvez, seja o grande diferencial da literatura barreteana. Ao promover uma
ideia de arte que está em consonância com a vida, com propósito humanista e de
alteridade. De maneira sucinta, o trabalho aponta para a ideia de que, além do autor
contribuir para um conceito mais real da literatura brasileira, ele, através de alguns
elementos da teoria da narrativa: espaço, tempo, personagens, revoluciona a teoria
da narrativa no sentido de se apropriar desse espaço, anteriormente burguês. Nesse
sentido, torna-se, quase impossível, fazer uma análise crítica da sua obra e da
literatura brasileira como um todo sem problematizar as relações estéticas e políticas
envolvidas na literatura
Exploring the potential of sweet sorghum (Sorghum bicolor (L.) Moench) grain meal as a supplement for diabetic patients in African diets
No full textIn the context of Africa's rich cultural and traditional practices in healthcare, this study explored the potential of sweet sorghum (Sorghum bicolor (L.) Moench) grain meal as a supplement for managing diabetes within African diets. Diabetes poses a significant health challenge in Africa, prompting the search for appropriate dietary interventions. Sweet sorghum, a versatile traditional African crop, possesses unique nutritional and phytochemical properties that may offer benefits for diabetes management. Through a thorough literature review of reputable sources, including PubMed, Science Direct, Google Scholar, and NCBI, this study examined sweet sorghum's glycemic index, impact on blood sugar levels, and influence of its high fibre content on blood sugar control and metabolism within the African diet context. Additionally, this study assessed the cultural acceptability and feasibility of incorporating sweet sorghum grain meal into conventional African recipes, considering its culinary adaptability and potential to enhance regional dietary customs. The findings of this study highlight the promising potential of sweet sorghum grain meal as a dietary supplement for managing diabetes within African diets, emphasizing its unique nutritional and phytochemical properties. Despite its promising attributes, challenges such as limited availability, processing, and preparation techniques were identified. By integrating existing evidence and considering the specifics of the African diet, this research elucidates the potential advantages of sweet sorghum grain meal as a dietary supplement in the fight against diabetes in Africa. This finding underscores the importance of evidence-based dietary recommendations and long-term diabetes management strategies tailored to African communities' cultural and nutritional contexts. This study recommends further research, community engagement, and legislative support to promote the adoption of sweet sorghum grain meal as a dietary supplement for managing diabetes in Africa, emphasizing the importance of evidence-based dietary recommendations tailored to African communities' cultural and nutritional contexts
Mode-division-multiplexing passive optical network with Low-modal crosstalk
No full textRecently, mode-division multiplexing (MDM) has been investigated in transmission systems and optical access networks for capacity enhancement. In this paper, recent progress in MDM optical passive networks (PON) enabled by low-modal crosstalk few-mode fibers (FMFs) and optical components is reviewed. All-fiber mode multiplexer/demultiplexers (MUX/DeMUX) composed of mode-selective couplers (MSCs) are introduced to simultaneously multiplex or demultiplex multiple modes. Few-mode circulators (FMCs) are employed to realize bidirectional MDM-PON transmission. Direct detection without complex multiple-input-multiple-output (MIMO) digital signal processing (DSP) is applied. Moreover, multidimensional PONs by cascading MDM optical distribution network (ODN) with conventional time-division multiplexing (TDM) and wavelength-division multiplexing (WDM) ODNs are proposed and experimentally demonstrated.CPCI-S(ISTP)1013
Vídeos do YouTube : aproximações e distanciamentos em relação ao processo de ensino, de aprendizagem e produção do conhecimento.
No full textPrograma de Pós-Graduação em Educação. Departamento de Educação, Instituto de Ciências Humanas e Sociais, Universidade Federal de Ouro Preto.Ao nos referirmos as redes sociais e as Tecnologias Digitais da Informação e Comunicação
(TDICs), podemos falar em Web 2.0 ou a segunda geração de serviços disponíveis na internet
que vem proporcionando práticas colaborativas via Web e a partir de contextos inovadores, surge
a plataforma YouTube como facilitador e agregador interativo, no contexto de videoaulas
disponíveis na plataforma. O estudo objetivou analisar as contribuições dos vídeos do YouTube
para o processo de ensino e de aprendizagem dos conteúdos abordados com estudantes da rede
estadual de ensino da cidade de Ouro Preto – MG, do 9° ano do ensino fundamental (n = 20) e do
1° ano do ensino médio (n = 10). Os dados foram coletados a partir de um questionário com
perguntas mistas e que traçou o perfil sociodemográfico da amostra, composta por indivíduos
com idades entre 14 e 16 anos, com predominância de estudantes do sexo feminino e da cor parda.
A análise de dados foi trabalhada considerando a análise de conteúdo proposta por Bardin (2011)
e a partir dos pressupostos abordados pela autora emergiram três categorias, “A percepção de
estudantes do 9° ano do ensino fundamental e do 1° ano do ensino médio sobre a plataforma
YouTube”, “A mediação pedagógica e a influência das TDICs neste processo” e “Tecnologias
audiovisuais associadas aos dispositivos de produção, reprodução e manipulação de conteúdos: O
caso da plataforma YouTube”. Os resultados indicam que os sujeitos pesquisados consideram a
plataforma YouTube como um recurso fundamental em seu processo educativo, reconhecem
aspectos interativos que a transformam em um ambiente virtual de aprendizagem e compreendem
a configuração de videoaulas disponíveis no YouTube, o que contribui para a predileção dos
sujeitos pelos vídeos. É perceptível que professores dos sujeitos pesquisados se utilizam deste
recurso como parte do processo de ensino ao considerar ações de mediação pedagógica, essencial
na desmistificação do conceito de nativos digitais e que a instituição familiar está inserida no
processo ao nos referirmos às TDICs. Com relação as disciplinas mais buscadas na plataforma,
verificamos a predominância de disciplinas como Matemática e Ciências Naturais. Foi observado
que os estudantes têm preferência por pesquisar e assistir videoaulas disponíveis no YouTube
através do seu smartphone e que preferem acompanhar estes vídeos em sua residência. Os
resultados do presente estudo podem subsidiar novas metodologias de ensino que favoreçam o
processo de ensino e aprendizagem com o intuito de contribuir para melhorar a relação do
binômio professor-estudante, favorecendo uma utilização coletiva, democrática e significativa de
redes sociais como a plataforma YouTube, mas ponderamos a importância da mediação
pedagógica neste processo, pois dependendo das práticas instituídas ou instituintes, as videoaulas
podem reafirmar práticas centradas no falar-ditar docente.When referring to social networks and Digital Information and Communication Technologies
(DICTs), we can talk about Web 2.0 or the second generation of services available on the internet
that has been providing collaborative practices on the Web and from innovative contexts, the
YouTube platform emerges as a facilitator and interactive aggregator, in the context of video
lessons available on the platform. The study aimed to analyze the contributions of YouTube
videos to the teaching and learning process off the content covered with students of state school
system in the city Ouro Preto – MG, middle school (9th grade) students and high school (1st
grade) students. Data was collected from a questionnaire with mixed questions that traced the
socio -demographic profile of the sample, composed of individuals aged between 14 and 16
years, with a predominance of female and brown students. It worked considering the content
proposed by Bardin (2011) and the assumptions addressed by the author, then three categories
emerged: “The perception of middle school (9th grade) and high school (1st grade) students on
the YouTube platform”, “Pedagogical mediation and the influence of DICTs in this process” and
“Audiovisual technologies associated with production devices, reproduction and manipulation of
content: The case of the YouTube platform”. Results indicate that the researched subjects
considered the YouTube platform as a fundamental resource in their education process,
recognising the aspects that transform it into a virtual learning environment and the configuration
of those lessons available, which contributes to the subjects predilection for videos. It’s
noticeable that teachers of the researched subjects use this resource as part of the teaching process
when considering pedagogical mediation and the influence of DICTs in this process” and
“Audiovisual technologies associated with production devices, reproduction and manipulation of
content: The case of the YouTube platform”. Results indicate that the researched subjects
consider the YouTube platform as a fundamental resource in their education process, recognise
aspects that transform it into a virtual learning environment and understand the configuration of
video the lessons available, which contributes to the subjects predilection for videos. It’s
noticeable that teachers of the researched use this resource as part of the teaching process when
considering pedagogical mediation actions which are essential in demystifying the concept of
digital natives and that the family institution is inserted in the process when referring to DICTs.
Regarding the most searched disciplines in the platform, we verified the predominance of
Mathematics and Natural Sciences. It was noted that students had a preference for researching
and watching the video lessons available on their smartphones and that they prefered to keep up
with these videos at home.The results of this study can subsidize new teaching methodologies
that favor the teaching and learning process in order to contribute to improve the teacher-student
relationship, favoring a collective, democratic and meaningful use of social networks such as the
YouTube platform, but we ponder the importance of pedagogical mediation in this process,
because depending on the practices instituted or instinctive, the video classes can reaffirm
practices centered on the teacher speaking

The results of this research are recommending the business strategy with market penetration, the author give an action plan for the next 5 years in order to make O’Corner more grow up and better than the other competitor. Keywords: business strategy, snack business, business model canva
Unsupervised Model Selection for Time-series Anomaly Detection
No full textAnomaly detection in time-series has a wide range of practical applications.
While numerous anomaly detection methods have been proposed in the literature,
a recent survey concluded that no single method is the most accurate across
various datasets. To make matters worse, anomaly labels are scarce and rarely
available in practice. The practical problem of selecting the most accurate
model for a given dataset without labels has received little attention in the
literature. This paper answers this question i.e. Given an unlabeled dataset
and a set of candidate anomaly detectors, how can we select the most accurate
model? To this end, we identify three classes of surrogate (unsupervised)
metrics, namely, prediction error, model centrality, and performance on
injected synthetic anomalies, and show that some metrics are highly correlated
with standard supervised anomaly detection performance metrics such as the
score, but to varying degrees. We formulate metric combination with
multiple imperfect surrogate metrics as a robust rank aggregation problem. We
then provide theoretical justification behind the proposed approach.
Large-scale experiments on multiple real-world datasets demonstrate that our
proposed unsupervised approach is as effective as selecting the most accurate
model based on partially labeled data.Comment: Accepted at International Conference on Learning Representations
