The Method of making Example in QuranMaking examples, used by all prophets (p.b.u.t) specially the prophet Mohammed (p.b.u.h) is one of the most effective methods of education to guide and train human. In many parts of holy Quran, some subjects such as history of nations and their fate and the surprises of creation has been narrated with emphasis on understanding some notes by narrated examples. The present article is to analyze the different dimensions of this method, the essence of making examples and its concept, estimators and essential of making example, the conditions in which the example leave an impression, the subjects and methods of examples from the holy Quran perspective.

Artificial Intelligence (AI) and especially Machine Learning (ML) can play a very important role in realizing and optimizing 6G network applications. In this paper, we present a brief summary of ML methods, as well as an up-to-date review of ML approaches in 6G wireless communication systems. These methods include supervised, unsupervised and reinforcement techniques. Additionally, we discuss open issues in the field of ML for 6G networks and wireless communications in general, as well as some potential future trends to motivate further research into this area.

Aprendizagem e Desenvolvimento De Jovens e Adultos Alfabetizados a Partir De Uma Abordagem Histórico-CulturalRESUMO: Este artigo apresenta os resultados de pesquisa que teve como objetivo investigar as contribuições que a aprendizagem da leitura e da escrita propicia ao desenvolvimento de jovens e adultos, bem como significados por eles atribuídos ao seu processo de alfabetização, tendo como base a abordagem histórico-cultural de Bakhtin, Vigotski e Leontiev e o materialismo histórico e dialético de Marx e Engels. O procedimento metodológico da referida investigação foi pautado na pesquisa-ação de Thiollent e Barbier, de cunho dialógico e interventivo. O lócus foi uma turma do BB Educar em São Sebastião (DF). Constatou-se que a aprendizagem da leitura e da escrita contribuiu para mudanças na forma de ser, pensar e agir dos educandos que, na sua percepção, empoderaram-se, tornaram-se referência para a comunidade e seus filhos mais novos, passando a adotar uma postura metacognitiva, ou seja, refletindo sobre o seu processo de aprendizagem, compreendendo a sua forma singular de pensar e ampli...

Psychiatric and mood disorders may play an important role in the development and persistence of irritable bowel syndrome (IBS). Previously, we hypothesized that stressinduced implicit memories may persist throughout life via epigenetic processes in the enteric nervous system (ENS), independent of the central nervous system (CNS). These epigenetic memories in the ENS may contribute to developing and perpetuating IBS. Here, we further elaborate on our earlier hypothesis. That is, during pregnancy, maternal prenatal stresses perturb the HPA axis and increase circulating cortisol levels, which can affect the maternal gut microbiota. Maternal cortisol can cross the placental barrier and increase cortisolcirculating levels in the fetus. This leads to dysregulation of the HPA axis, affecting the gut microbiota, microbial metabolites, and intestinal permeability in the fetus. Microbial metabolites, such as short-chain fatty acids (which also regulate the development of the fetal ENS), can modulate a range of diseases by inducing epigenetic changes. These mentioned processes suggest that stress-related, implicit long-term epigenetic memories may be programmed into the fetal ENS during pregnancy. Subsequently, this implicit epigenetic stress information from the fetal ENS could be conveyed to the CNS through the bidirectional microbiota-gut-brain axis (MGBA), leading to perturbed functional connectivity among various brain networks and the dysregulation of affective and pain processes.

National audienceThis paper is an original empirical tentative to explain collective action outcome in the domain of food safety. We examine conditions and institutions that influence pesticide residues level in vegetables using econometric analysis on data gathered by 60 farmers organizations in Vietnam. Findings suggest that collective action affects safety by providing members with technical assistance, monitoring and certification. The expected increase of free-riding in larger groups is not an issue when members are properly supported and monitored. The contribution of public authorities and ecological conditions to safety remains controversial while market forces do not seem able to drive the production of safer vegetables
