Influence of plant density and hilling on yield and profitability of arrowroot

The global production of arrowroot is minimal, and this may be partially associated to the lack of standardized agronomic techniques for its commercial cultivation. This study aimed to assess the yield and profitability of arrowroot plants (‘Comum’ cultivar) grown using different plant spacings in the cropping row (20 cm, 25 cm, 30 cm and 35 cm) and a varying number of hilling applications (0, 1 and 2). The treatments were arranged in a 4 x 3 factorial scheme, in a randomized experimental block design, with six replications. After harvesting, the fresh and dry matter yields of leaves, rhizomes and roots were determined. Production costs and gross and net incomes were also calculated. The highest yields for fresh leaves (8.75 t ha-1), rhizomes (32.92 t ha-1) and roots (8.45 t ha-1) were obtained with a plant spacing of 20 cm. No interaction between the factors, neither significant differences for the use or not of hilling, were observed on the analyzed variables. The costs per hectare ranged from BRL 8,488.83 (35 cm without hilling) to BRL 10,376.23 (20 cm with two hillings). The highest yields and gross and net incomes were obtained with the spacing of 20 cm between plants

A "masculinização" da produção de leite.

O fortalecimento de organizações sociais que possibilitaram fazer da produção de leite uma atividade destinada ao mercado provocou profundas mudanças na divisão sexual do trabalho. A análise sociológica das trocas intradomiciliares nos estabelecimentos rurais familiares mostra que tradições culturais, diferenças de poder entre os gêneros e contextos sociais que ampliam diferenças de acesso aos mercados entre homens e mulheres são as bases sociais e culturais de uma hierarquia estruturada segundo sexo e geração, no qual as mulheres, especialmente as mais jovens, ocupam posições de grande desvantagem. Com o fortalecimento de cooperativas, a produção de leite passou a ocupar um lugar de destaque no provimento de recursos da família, mas o domínio da atividade foi deslocado para o controle masculino. Esse foi um dos resultados não esperados da forma como as organizações conduziram o processo de modernização da produção e de reestruturação dos mercados, que reforçaram ainda mais o domínio masculino sobre a produção familiar e um aumento das desigualdades de gênero no acesso aos recursos

O PAPEL SOCIAL DO INSTAGRAM: PERCEPÇÃO DOS ACADÊMICOS DE EDUCAÇÃO FÍSICA SOBRE AS REPRESENTAÇÕES CORPORAIS

This article aimed to understand the social role of Instagram and its influence on the schemes of body representations of young users of the network, all academics of a Physical Education course. We started from the notion that Instagram is part of a virtual space in which a process of constant creation takes place, forming the cyberculture. There, the number of likes received by posts in some applications becomes a determining factor for those who seek personal and professional prominence in their profiles. For this descriptive, cross-sectional, and qualitative study with a field-research design, 26 students answered a questionnaire. The results showed that their representations relate to the individual view of how the body presents itself and how subjects express themselves in a sociocultural dimension. To these students, the influence of Instagram on body representations is conceived as multidimensional, being highlighted from three essential aspects: the social, personal, and professional environment. It is concluded that these young academics have their professional and personal activities strongly interpellated by Instagram, which indicates the need of developing more research able to reflect on the relationship between social networking and Physical Education.  Este artículo tuvo como objetivo comprender el papel social de Instagram y su influencia en los esquemas de representación corporal de jóvenes usuarios de la red, estudiantes de un curso de Educación Física. Partimos de la noción de que el Instaram es parte de un espacio virtual en el que se lleva a cabo un proceso de creación constante y formativo de cibercultura. En él, el número de likes que reciben las publicaciones en algunas aplicaciones se convierte en un factor determinante para quienes buscan un protagonismo personal y profesional en sus perfiles. Para este estudio descriptivo, transversal con enfoque cualitativo, basado en una investigación de campo, 26 estudiantes respondieron un cuestionario. Los resultados mostraron que sus representaciones relacionan la visión individual de cómo se presenta el cuerpo y cómo los sujetos se expresan en una dimensión sociocultural. La influencia de Instagram en las representaciones corporales de estos estudiantes se concibe como multidimensional, destacándose desde tres aspectos clave para su formación: el entorno social, personal y profesional. Se concluye que estos jóvenes académicos tienen sus actividades profesionales y personales fuertemente cuestionadas por Instagram, siendo necesarias más investigaciones para reflexionar sobre la relación entre las redes sociales y la Educación Física.Este artigo teve como objetivo compreender o papel social do Instagram e sua influência nos esquemas de representações corporais de jovens usuários da rede, acadêmicos de um curso de Educação Física.

Os danos, efeitos adversos e agravos á saúde mental gerados pela atividade policial

A atividade policial vem impactando na saúde mental dos agentes, conectando traumas adquiridos em ocorrências, vivência diária na violência descontrolada, fatores estressores, condições insalubres de trabalho, e como há uma repercussão desfavorável na mente. Constatando assim, mudanças comportamentais indissociáveis à atividade laboral exercida: alcoolismo, uso de drogas, ansiedade, depressão, Síndrome de Burnout, TEPT.  O trabalho visa realizar revisão bibliográfica narrativa, utilizando conceitos números, dados, pesquisas, questionários em instituições policiais. Fato inconteste, é que o tema encontra-se cada dia mais presente no dia a dia da sociedade com ocorrências policiais que acabam saindo fora do planejado, com uso excessivo da força, emprego em desconformidade da técnica, formas letais de ação em possíveis intervenções menos vigorosas, sendo advindas, em sua maioria, de aspectos de cunho psicológico mal resolvidos. Assim, resta também prejuízo para a própria Instituição que tem seu reconhecimento social abalado, convive com atestados, tem bons servidores fora de sua área, chegando à fase máxima de chegar ao ponto de aposentadorias e uma exacerbada e grave quantidade crescente de suicídios

Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Soutenir les capacités langagières et littéraciques des enfants à travers le développement professionnel des éducatrices et éducateurs de la petite enfance

De nombreuses recherches affirment que les capacités langagières et littéraciques précoces constituent des prédicteurs majeurs de la réussite scolaire ultérieure, celle-ci favorisant, à plus long terme, une meil- leure égalité des chances en vue d’une insertion professionnelle et sociale. En raison de la forte augmenta- tion de leur fréquentation, les structures d’accueil extrafamilial des jeunes enfants jouent aujourd’hui un rôle fondamental dans le développement langagier et littéracique, créant des opportunités de mise en œuvre de nouvelles pratiques éducatives et suscitant un intérêt accru de la part de la recherche scientifique pour l’éducation des jeunes enfants en contexte collectif. Appuyé sur les savoirs et démarches développées en Psychologie du développement de l’enfant, en Psy- cholinguistique, en Didactique des langues et en Formation des adultes, le projet CapLang adopte une pers- pective interdisciplinaire et interprofessionnelle pour mettre en place un dispositif de formation et de re- cherche visant à soutenir les capacités langagières et littéraciques des jeunes enfants fréquentant des institutions de la petite enfance par et à travers le renforcement des compétences professionnelles des éducatrices et éducateurs de l’enfance
