The role of “Food Hubs” in the relationship construction between organic farm producers through short chain supply in Porto Alegre (RS)

Este artigo visa analisar o papel de foodhubs, cujo conceito pode ser entendido como o de multiplataformas que comercializam produtos orgânicos frescos, que geram relacionamentos interativos entre produtores e consumidores. Partindo dessa premissa, para que possamos compreender essa transcendência conceitual, foram escolhidos 3 food hubs na região metropolitana de Porto Alegre como estudo para verificar e perceber como ocorrem essas relações. Através da pesquisa, numa primeira análise, foi possível observar as várias iniciativas que geram fidelização, engajamento, empatia entre as partes e, sobretudo, o incentivo que leva à interação e conhecimento mútuo. Dessa forma, esses food hubs se mostraram como promotores da relação produtor-consumidor, muito além da mera comunicação de informações, que acabam por incentivar as interações a longo prazo e a empatia entre os interessados envolvidos em todo o processo.This article will analyze the role of food hubs, whose concept can be understood as that of multiplatform that sells fresh organic products, which generate interactive relationships between producers and consumers. Based on this premise, so that we can understand this conceptual transcendence, 3 food hubs in the metropolitan region of Porto Alegre were chosen as a study to verify and understand how these relationships occur. Through the research, in a first analysis, it was possible to observe the various initiatives that generate loyalty, engagement, empathy between the parties and, above all, the incentive that leads to interaction and mutual knowledge. In this way, these food hubs proved to be promoters of the producer-consumer relationship, far beyond the mere communication of information, which end up encouraging long-term interactions and empathy between the stakeholders involved in the entire process

Esse artigo foi desenvolvido através da coleta preliminar, desenvolvimento e transposição de dados pesquisados em relação aos agentes econômicos que comercializam produtos hortícolas orgânicos na região metropolitana de Porto Alegre (RS) através das mídias digitais, tais como sites, marketplaces, redes sociais e aplicativos de mensagem instantânea. Para fins de construção de uma base de dados inicial, é analisado a formação e processo de funcionamento desse mercado, em contraste com os últimos movimentos e expressões que suscitam uma maneira diferenciada de encarar o alimento e estilo de vida. Entendendo assim, que a atuação desses agentes se mescla na diegese dos mercados de comercialização de orgânicos de uma maneira única situada em seu tempo, levando em conta a crise social do presente que se apresenta no século XXI. Pois é através das novas tecnologias, o acesso e a globalização, é preciso se reinventar e readaptar às novas conjunturas sociais e econômicas que se apresentam. Para tanto, a fim de elucidar essas análises dessa tipologia de e-commerce e sua relação na comercialização de orgânicos, se recorre a uma análise pensando numa perspectiva das cadeias de distribuição como norteador metodológico para avaliar de que maneira esse comércio opera. Dessa forma, se concluiu que alguns aspectos são relevantes para a manutenção e bom funcionamento desse tipo de comércio, tais como: Produto local e fresco, respeito a sazonalidade, ser direto do produtor, fair trade e o preço justo, presença de cooperativas/associações e venda de alimentos orgânicos e saudáveis.This article was developed thinking about to mounting a preliminary database, development, and transposition of researched data in relation to the economic agents that commercialize organic vegetables in the metropolitan region of Porto Alegre (RS) through digital media, such as websites, marketplaces, social networks and instant messaging applications. For the purposes of building an initial database, the formation and functioning process of this market will be analyzed, in contrast to the latest movements and expressions that give rises to a new way of looking at food and lifestyle. Understanding thus, that the performance of these agents is mixed in the diegesis of the organic commercialization markets in a unique way of expression situated in its time yourself, considering the social crisis of the present that presents itself in the 21st century. Because it is through all those new technologies, access, and globalization, it is necessary to reinvent and readjust to the new social and economic conjunctures that present themselves. Therefore, to elucidate these analyzes of this type of e-commerce and its relationship in the marketing of organic products, we resorted to an analysis thinking in a perspective of the distribution chains as a methodological guide to evaluate the way in which this trade operates. So, we concluded some relevant aspects to maintain and good work of this kind of business as: Local and fresh products, seasonality, products direct from the producer, fair trade and price, presence of cooperatives and associations and selling health and organic food.Este artículo se desarrolló por una recopilación preliminar, desarrollo y transposición de datos investigados en relación a los agentes económicos que comercializan vegetales orgánicos en la región metropolitana de Porto Alegre (RS) por los medios digitales, como sitios web, marketplaces, redes sociales y aplicaciones instantáneas. mensaje.

Common and rare variant association analyses in amyotrophic lateral sclerosis identify 15 risk loci with distinct genetic architectures and neuron-specific biology

A cross-ancestry genome-wide association meta-analysis of amyotrophic lateral sclerosis (ALS) including 29,612 patients with ALS and 122,656 controls identifies 15 risk loci with distinct genetic architectures and neuron-specific biology. Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with a lifetime risk of one in 350 people and an unmet need for disease-modifying therapies. We conducted a cross-ancestry genome-wide association study (GWAS) including 29,612 patients with ALS and 122,656 controls, which identified 15 risk loci. When combined with 8,953 individuals with whole-genome sequencing (6,538 patients, 2,415 controls) and a large cortex-derived expression quantitative trait locus (eQTL) dataset (MetaBrain), analyses revealed locus-specific genetic architectures in which we prioritized genes either through rare variants, short tandem repeats or regulatory effects. ALS-associated risk loci were shared with multiple traits within the neurodegenerative spectrum but with distinct enrichment patterns across brain regions and cell types. Of the environmental and lifestyle risk factors obtained from the literature, Mendelian randomization analyses indicated a causal role for high cholesterol levels. The combination of all ALS-associated signals reveals a role for perturbations in vesicle-mediated transport and autophagy and provides evidence for cell-autonomous disease initiation in glutamatergic neurons

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| < 0.03 at 95% confidence level.

An embedding technique to determine ττ backgrounds in proton-proton collision data

An embedding technique is presented to estimate standard model tau tau backgrounds from data with minimal simulation input. In the data, the muons are removed from reconstructed mu mu events and replaced with simulated tau leptons with the same kinematic properties. In this way, a set of hybrid events is obtained that does not rely on simulation except for the decay of the tau leptons. The challenges in describing the underlying event or the production of associated jets in the simulation are avoided. The technique described in this paper was developed for CMS. Its validation and the inherent uncertainties are also discussed. The demonstration of the performance of the technique is based on a sample of proton-proton collisions collected by CMS in 2017 at root s = 13 TeV corresponding to an integrated luminosity of 41.5 fb(-1).Peer reviewe

Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe
