title: Filling gaps in the ecological knowledge on Auchenipteridae catfishes (Ostariophysi: Siluriformes): first data for Trachelyichthys exilis

description: ABSTRACT The feeding habit of Trachelyichthys exilis is described for the first time, with additional comments on its growth type and size at sexual maturity. We analyzed 42 specimens from the Amanã Reserve (Amazonas state, Brazil) collected with a seine net amidst stands of floating herbaceous vegetation during the dry season of 2002. Stomach contents revealed a predominantly carnivorous habit (tending to piscivorous), an isometric growth type, and size at maturity around 5.5 cm standard length. Based on the biological characteristics of the consumed prey, we presume that T. exilis forage actively during the twilight/night around and among the root tangle of herbaceous vegetation, preying upon nocturnally active animals such as small fishes and aquatic invertebrates, and/or close to the water surface, where diurnally active prey usually rests. Our findings provide essential information to fill knowledge gaps on the natural history of auchenipterid catfishes, especially on trophic ecology.

title: The pandemic nature of agribusiness’ socio-environmental and sanitary disasters

description: ABSTRACT The production process of the chemical-dependent agribusiness is one of the largest generators of risk, socio-environmental, and sanitary disasters of a pandemic nature. It acts on the social determination of health-disease-environmental damages, leading to critical situations, risks and vulnerabilities, human exploitation, acute and chronic poisoning, and ecological degradations as the effects of their harm to establish interrelations between production-environment-society. The sector has contributed directly to the globalized ecological and sanitary crisis by giving rise to syndemics, food insecurity, water and contamination, besides producing new and/or reemergious infectious diseases. In this critical essay, based on the studies of the Nucleus for Environmental Studies and Workers Health of the Federal University of Mato Grosso, different elements that are menacing, destructive, degrading, and violators of workers’ right to health and environmental health are demonstrated in the main links in the production chain of agribusiness. Next, using public document analyses, state regulations, and data from health surveillance systems, the processes of food and water contamination arising from agrochemicals are exposed, as well as a criticism of the political tendencies that revolves around agribusiness. Finally, we highlight the pressing need of an agroecological transition as a response to the diseases and syndemics of agribusiness.

title: Pirarucu larviculture in green water provides heavier fish and modulates locomotor activity

description: ABSTRACT The green water technique uses microalgae in the water of indoor larviculture, providing a darker environment to favor fish growth, welfare and health. We evaluated growth performance and locomotor activity after light exposure of pirarucu (Arapaima gigas) larvae reared in green or clear water. During one test, pirarucu larvae (3.6 ± 0.3 cm; 0.36 ± 0.1 g) were reared in 50-L circular tanks (n = 3 per treatment, 50 larvae per tank) in a static system containing green water [microalgae (w3algae; Bernaqua® 10 g m-3) added] or clear water (control). Fish weaning was achieved by co-feeding with Artemia nauplii and microdiets for seven days until full microdiet substitution. Larvae were biometrically evaluated on days 10, 17 and 24 to assess growth performance. In a second test, the locomotor activity of the larvae was analyzed before and after light exposure (1400 ± 60 lx) for 48 h according to an ethogram. After 24 days, the larvae reared in the green water were significantly heavier than those from the clear water, and displayed significantly fewer circular swimming movements. Body cortisol increased in both groups after light exposure. The microalgae provided an additional food source for larvae, with positive impact on growth until day 17 of larviculture. Green water can be a strategy to achieve better results in pirarucu larviculture, especially during and up to 10 days after the co-feeding period.

title: Neoliberalism and income distribution in Latin America

description: ABSTRACT This paper reviews the principal neo-liberal policy measures instituted in Latin America in the last decade and their impact on equity. It first emphasizes the difficulty of separating the impact of liberalization measures from the necessary fiscal adjustments of the 1980s, and their transitional vs long run effects, and then places the observed movements in distribution in global and historical context. The second part places several innovations of neo-liberal regimes in historical perspective and argues that their overall impact is unlikely to be regressive, and that previous regimes were probably not especially progressive. Over the long run, developments in factor markets are likely to be of overriding importance - the demand side, driven by reoriented industrial growth and the increasing importance of the service sector, interacting with the relative supplies of skilled and unskilled labor - are likely to be of overriding importance in determining the evolution of the distribution of income.

title: Principles for the study of the marginal poetry materialities

description: Abstract In this paper, I propose a study about the materialities of the marginal poetry. Since the exhibition “Marginal Poetry: word and book”, in 2013, promoted by the IMS, and the FLIP 2016, in which Ana Cristina Cesar was chosen as the honored author, the marginal poetry has returned to the spotlights of the Brazilian cultural scene. The title of the IMS exhibition rightly suggests the organic relation between the marginal poem and its materiality. However, this is not reflected in the critical fortune of this poetry, which perhaps results from the fact that field studies on the materialities of literature are still incipient in Brazil. Thus, this paper aims to accomplish a critical review of the marginal poetry from the perspective of the materialities of literature. Thereby it is intended both to undo commonplaces of criticism and to promote a necessary re-reading of this poetry, since although its mode of production based on self-publishing is always suggested, its implications have not yet been properly recognized.

title: A Brazilian cost-utility analysis of trabecular micro-bypass with iStent inject® for the treatment of open-angle glaucoma

description: ABSTRACT Purpose To evaluate the cost-utility of the iStent inject® for the treatment of mild-to-moderate open-angle glaucoma (OAG) within the Brazilian Unified Health System (SUS). Methods A Markov model was developed, in which the effectiveness outcome measure was the incremental cost-effectiveness ratio (ICER: R$ / QALY quality-adjusted life-year). Direct medical costs were obtained from the SUS perspective. The base case comprised of a hypothetical cohort of patients with OAG using topical medication and being managed according to the Clinical Protocol and Therapeutic Guidelines (PCDT) and a real-world setting based on data from Datasus. The model’s robustness through sensitivity analyses was tested. Results In the PCDT base case setting, the trabecular micro-bypass implant provided gains of 0.47 QALYs and an ICER of R$7,996.66/QALY compared to treatment with topical medication. In the real-world setting based on data from Datasus, the trabecular micro-bypass implant, provided gains of 0.47 QALYs and an ICER of R$4,485.68/QALY compared to treatment with topical medication. The results were robust to sensitivity analyses. Conclusion Incorporating iStent inject® to SUS provides an improvement in the patient’s quality of life with an additional cost that warrants the benefit provided to patients. Results may be considered cost-effective compared to topical medication.

title: Soil phosphorus fractions and their relation to leaf litterfall in a central Amazonian terra firme rainforest

description: ABSTRACT Phosphorus (P) cycling is an important yet poorly studied aspect of the macronutrient balance in tropical rainforest ecosystems. As soil P occurs in different organic and inorganic forms (fractions) with varying degrees of lability, we hypothesized that these fractions will vary between soil types, and temporally within soil types. Additionally, we hypothesized a direct influence of leaf litterfall P input on soil total P and soil P fractions. We collected soil and leaf litter samples from three soil types in a central Amazonian lowland rainforest in Brazil over five months, and used a modified Hedleys fractionation method to determine six organic and inorganic soil P fractions, and also total, labile and residual P. Leaf litterfall P concentrations were determined colorimetrically. Soil inorganic and organic P fractions varied between soil types and across months, but soil type and month interactions were mostly non-significant. Some inorganic P fractions (Pi-NaOH) peaked while the organic fractions (Po-NaOH) fell and vice versa. Leaf litterfall production and leaf litterfall P input peaked around two months following the wettest month. Leaf litterfall P input was a significant predictor of Po-NaHCO3, a bioavailable P fraction. Future studies on P cycling in terrestrial ecosystems should examine the roles played by individual soil P fractions as they cycle asynchronistically and differently across soil types.

title: DIFFICULTY AND DISCRIMINATION PARAMETERS OF THE KTK INSTRUMENT MOTOR TASKS: AN ANALYSIS FROM ITEM RESPONSE THEORY

description: ABSTRACT In the last decades, the use of Item Response Theory (IRT) has been implemented due to the complexity of statistical calculations that allows for in-depth analysis of educational tests, questionnaires and lists of items applied in different areas such as psychometry, sports ranking and pedagogy. Based on this premise, this study aimed to verify the suitability of the KTK motor tasks analyzing the degree of difficulty and discrimination parameters of each motor task. A total of 385 children aged 5 to 14 years participated in the study. The instrument evaluated was the KTK (Körperkoordinationstest für Kinder), consisting of four motor tasks: balance beam, single-pedal jumps, side jumps and platform transposition. Analyzes were conducted from the raw data acquired in each motor task. In order to verify the factor structure of the theoretical matrix underlying the test, an exploratory factor analysis was performed, followed by a confirmatory factor analysis. The difficulty and discrimination parameters of each motor task were analyzed using the gradual response model, based on the Item Response Theory (IRT). The results corroborate the factor structure suggested in the original version of the KTK, presenting only one factor, called motor coordination. The AFC indicators were acceptable, indicating good quality of the model adjusted for the sample. It is concluded that the IRT analysis evidenced differences in the parameters of difficulty and discrimination between the KTK motor tasks, demonstrating the importance of considering a weighting in the creation of normative tables of motor assessments.
