Projetos de modernidade: autoritarismo, eugenia e racismo no Brasil do século XX

O presente artigo tem como ponto de partida a ideia de modernidade no Brasil e seu desdobramento na sociedade brasileira, com um projeto autoritário que valorizou o “branqueamento” do país. Nesse sentido, discutiremos, ainda que brevemente, o conceito de modernidade. Para explicar o fenômeno da modernidade pela via do autoritarismo, usaremos o conceito de nacionalismo autoritário. A questão racial é o enfoque central da discussão; assim, faremos uma síntese do pensamento social brasileiro de meados do século XIX aos anos 30 do século XX, para discorrermos sobre o conceito de eugenia no Brasil e da recepção das teorias racialistas europeias nesse país.En este artículo se toma como punto de partida la idea de modernidad en Brasil y su despliegue en la sociedad brasileña con un proyecto autoritario que valora el “blanqueamiento” del país. En este sentido, discutiremos, aunque con brevedad, el concepto de modernidad. Para explicar el fenómeno de la modernidad a través del autoritarismo, utilizaremos el concepto de nacionalismo autoritario. La cuestión racial es el foco central de la discusión, por lo que haremos una síntesis del pensamiento social brasileño de mediados del siglo XIX hasta los años treinta, para tratar acerca de la idea de eugenesia en Brasil y la recepción de las teorías racistas europeas en este país.This article takes as its starting point the idea of modernity in Brazil and its deployment in Brazilian society by means of an authoritarian project that values the “whitening” of the country. In this sense, we will discuss, albeit briefly, the concept of modernity. To explain the phenomenon of modernity through authoritarianism, we will focus on the concept of authoritarian nationalism. The racial issue is the focal point of the discussion, so we will present a synthesis of Brazilian social thought from the mid-19th century to the 1930s, in order to deal with the idea of eugenics in Brazil and the reception of European racist theories in that country

Older Compared With Younger Adults Performed 467 Fewer Sit-to-Stand Trials, Accompanied by Small Changes in Muscle Activation and Voluntary Force

Background: Repetitive sit-to-stand (rSTS) is a fatigue perturbation model to examine the age-effects on adaptability in posture and gait, yet the age-effects on muscle activation during rSTS per se are unclear. We examined the effects of age and exhaustive rSTS on muscle activation magnitude, onset, and duration during ascent and descent phases of the STS task. Methods: Healthy older (n = 12) and younger (n = 11) adults performed rSTS, at a controlled frequency dictated by a metronome (2 s for cycle), to failure or for 30 min. We assessed muscle activation magnitude, onset, and duration of plantar flexors, dorsiflexors, knee flexors, knee extensors, and hip stabilizers during the initial and late stages of rSTS. Before and after rSTS, we measured maximal voluntary isometric knee extension force, and rate of perceived exertion, which was also recorded during rSTS task. Results: Older vs. younger adults generated 35% lower maximum voluntary isometric knee extension force. During the initial stage of rSTS, older vs. younger adults activated the dorsiflexor 60% higher, all 5 muscle groups 37% longer, and the hip stabilizers 80% earlier. Older vs. younger adults completed 467 fewer STS trials and, at failure, their rate of perceived exertion was ~17 of 20 on the Borg scale. At the end of the rSTS, maximum voluntary isometric knee extension force decreased 16% similarly in older and younger, as well as the similar age groups decline in activation of the dorsiflexor and knee extensor muscles (all p < 0.05). Conclusion: By performing 467 fewer STS trials, older adults minimized the potential effects of fatigability on muscle activation, voluntary force, and motor function. Such a sparing effect may explain the minimal changes in gait after rSTS reported in previous studies, suggesting a limited scope of this perturbation model to probe age-effects on muscle adaptation in functional tasks

Age-specific modulation of intermuscular beta coherence during gait before and after experimentally induced fatigue

We examined the effects of age on intermuscular beta-band (15-35 Hz) coherence during treadmill walking before and after experimentally induced fatigue. Older (n = 12) and younger (n = 12) adults walked on a treadmill at 1.2 m/s for 3 min before and after repetitive sit-to-stand, rSTS, to induce muscle fatigability. We measured stride outcomes and coherence from 100 steps in the dominant leg for the synergistic (biceps femoris (BF)-semitendinosus, rectus femoris (RF)-vastus lateralis (VL), gastrocnemius lateralis (GL)-Soleus (SL), tibialis anterior (TA)-peroneus longus (PL)) and for the antagonistic (RF-BF and TA-GL) muscle pairs at late swing and early stance. Older vs. younger adults had 43-62% lower GL-SL, RF-VL coherence in swing and TA-PL and RF-VL coherence in stance. After rSTS, RF-BF coherence in late swing decreased by similar to 20% and TA-PL increased by 16% independent of age (p = 0.02). Also, GL-SL coherence decreased by similar to 23% and increased by similar to 23% in younger and older, respectively. Age affects the oscillatory coupling between synergistic muscle pairs, delivered presumably via corticospinal tracts, during treadmill walking. Muscle fatigability elicits age-specific changes in the common fluctuations in muscle activity, which could be interpreted as a compensation for muscle fatigability to maintain gait performance

Performance of Millet Cultivars in Succession to Field Crop of Beans in Southern Portion of State of Minas Gerais - Brazil

This trial was carried out at the Department of Animal Science - Universidade Federal de Lavras (UFLA), from February to June, 1997. It was evaluated the performance of three millet [Pennisetum glaucum (L.) R. Br.] cultivars, as a second crop (Common, BN 2 and CMS 02) and four sowing dates (02/22, 03/14, 04/03 and 04/23). The three millet cultivars were sown after a cropping of beans (Phaseolus vulgaris L.) by the end of the rainy season, with no additional fertilization. It was used the randomized block design in a split-plot scheme, allocating the sowing dates on the main plots and the cultivars on the subplots. There was a significant effect of sowing dates upon tiller height and density of millet cultivars. The residual fertilization of the rainy season beans’ crop was not enough to allow a millet to reach high yields. The average yield value for the three cultivars and four sowing dates was 3.27 t.ha-1 of DM. For the region of Lavras-MG, millet can be used in a succession cultivation, as the second crop, using cultivars Common and BN 2 sowed up to mid-March and it is necessary to use at least nitrogen and potassium for topdress fertilization
