Published: July 2021

Abstract: Introduction: Health assistance reorganization has been oriented, since the Unified Health System (SUS) creation, by a proposal of expansion and strengthening of Primary Health Care (PHC). In this context, the scarcity of trained professionals is considered one of the main challenges for PHC consolidation. Among the career options after graduation, most physicians choose to seek focal specializations to work in other health care levels. Objective: Therefore, this quantitative study aims to analyze the prevalence and associated factors of medical students’ interest in following a career in PHC. Method: A cross-sectional study was conducted with medical students attending the last two years in four medical schools in the state of Minas Gerais, Brazil. A total of 524 students participated by answering a self-administered questionnaire, which was prepared by the authors, including questions regarding sociodemographic and economic profile, interaction with PHC during undergraduate school, career intention and intention to attend the Family and Community Medicine Residency (FCMR) program. Results: The results showed that 26.3% of the respondents indicated interest in following a career in PHC, a higher percentage when compared to previous studies. Regarding PHC being a temporary work choice, 79,3% of the participants indicated that they intend to work in this field after graduation. Ten percent of the students informed they intend to attend the FCMR program. Among the factors associated with the intention to work in PHC, a successful PHC experience during undergraduate school stands out. Conclusion: The results should be taken into consideration by health and medical education managers, fostering strategies that promote successful PHC experiences, encouraging learning-service integration and including students in a consolidated PHC network during undergraduate school. Initiatives such as increasing the workload in PHC during undergraduate school, increasing the number of FMC specialized teachers and health network improvement in the municipalities where these Higher Education Institutions are located can be powerful actions toward increasing the graduating students’ interest to work in PHC.

Published: July 2021

Abstract The Xingu River has one of the most diverse fish faunas in the Amazon region. Loricariidae stands out as the most diverse family in the basin, comprising more than 60 species distributed over 26 genera. Species of Loricariidae are some of the most economically valued in the ornamental market worldwide. The loss of fishing environments in Altamira region due to dam impacts is driving a shift of ornamental fishing to areas upstream, among which are included the Xingu River and Iriri River Extractive Reserve Areas. Thus, the objective of this work was to inventory fish species with ornamental potential in these extractive reserves to serve as a baseline to help guide the future management of ornamental fishing in those areas. Thirty-two species of Loricariidae were collected in these reserves through either free diving or diving with compressed air. The composition of species varied according to the sampling method and area. The majority of species found in the reserves are also found in the impacted areas of Belo Monte near Altamira. The study areas showed high diversity of fish species in rapids environments, suggesting that this area could serve as an additional source of income for the residents of these reserves.

Published: July 2021

Abstract A new species of miniature fish of the characid genus Priocharax is described from a small lake near the rio Ipixuna, rio Purus drainage, Amazonas State, Brazil. It is distinguished from all congeners except P. pygmaeus by the lower number of teeth on the maxilla and dentary. It differs from P. pygmaeus by the presence of two postcleithra and 22–27 branched anal-fin rays (vs absence and 19–22). The new species is further distinguished from other species of Priocharax by a combination of characters involving the number of pelvic-fin rays and branched anal-fin rays, the number of postcleithra, the shape of postcleithrum 3, and the absence of the claustrum. Molecular evidence based on COI sequences of all valid species of Priocharax also corroborates the validity of this new species.

ABSTRACT This study aimed to compare three methods of estimating the optimum plot size to evaluate the fresh matter productivity of pearl millet (Pennisetum glaucum L.), slender leaf rattlebox (Crotalaria ochroleuca), and showy rattlebox (Crotalaria spectabilis). Twenty-seven uniformity trials were carried out with pearl millet, slender leaf rattlebox, and showy rattlebox cultivated alone and intercropped. Fresh matter productivity was evaluated in 972 basic experimental units (BEU) of 1 m × 1 m (36 BEU per trial). The optimum plot size was determined using the methods modified maximum curvature, linear response with plateau model, and quadratic response with plateau model. The optimum plot size differs between methods and decreases in the following order: quadratic response with plateau model (9.94 m2), linear response with plateau model (7.41 m2), and modified maximum curvature (3.49 m2). The optimum plot size to evaluate the fresh matter productivity of pearl millet, slender leaf rattlebox, and showy rattlebox cultivated alone or intercropped is 7.41 m2. This size could be used as a reference for future experiments.

Published: July 2021

ABSTRACT The objectives of the tests were to evaluate concentrations of indolebutyric acid (IBA) combined with different types of cuttings and grafting methods on the vegetative propagation of cajazeira-dejabuti (S. testudinis). The experiment with stem cuttings was conducted in a greenhouse with an intermittent misting system. The experimental design was completely randomized in a 5 x 6 factorial arrangement consisting of five cutting types: apical, medial, basal, stratified, and tanchan, and six IBA concentrations: 0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg kg-1, with four replications of ten cuttings. The experiment with the root cuttings followed a randomized block design composed of six IBA concentrations (0, 1,000, 2,000, 3,000, 4,000, and 5,000 mg kg-1) with four replications, evaluating after 120 days the percentages of live, sprouted, rooted, and calloused cuttings, and the number and dry mass of roots and sprouts. Five grafting methods (chip budding, shield budding, cleft grafting, wedge grafting, and splice grafting) were tested by evaluating the graft success and sprouting percentages at 30 and 60 days after grafting, respectively. Statistical analyses were performed using the Kruskal-Wallis non-parametric test. The IBA concentrations of 0, 2,000, 3,000, and 5,000 mg kg-1 increased the number of sprouts in tanchan cuttings. The tanchan cuttings showed the highest survival and percentage of sprouts regardless of the IBA concentration. The IBA concentration of 2,200 mg kg-1 promotes higher rooting rates in root cuttings. Splice grafting provides higher graft success and sprouting rates.

ABSTRACT Nitrogen is the second nutrient most demanded by arugula. However, the positive effect it has on yield can negatively impact the quality of this vegetable, with negative effects on human health. Two experiments (summer and autumn) were carried out to evaluate the effect of N rates (0, 50, 100, 150, 200 and 250 kg ha−1) on the arugula growth, yield and quality (nitrate content). Each experiment was set up in a randomized block design with four replications. Increasing rates of N reflected positively on leaf N content and thus, higher and desirable values of height, leaf number, leaf area and plant dry mass were obtained in both growing seasons. Consequently, the yield had significant increase, which N was maximized in summer (4.9 kg m−2) and autumn (2.6 kg m−2) and leaf N of 29.4 and 27.0 g kg−1, respectively, at rates of 250 and 213 kg ha−1 and both growing seasons. The higher rate the higher foliar nitrate content of arugula, in summer (2931.3 mg kg−1) and autumn (4218.4 mg kg−1). The foliar nitrate content in both crop season do not reach the risk level to human being heath.

ABSTRACT Cenostigma pyramidale, a pioneer species presents in all different successional stage (early, intermediate and late) of fifteen natural regeneration areas of Caatinga after land used changed and abandonment was used to investigates the morphological and physiological attributes that are very important to xeromorphic conditions as against herbivories. Leaf samples were collected to evaluate the percentage of the herbivory and index of sclerophylly. Anatomy, histochemistry, total phenolic content, epicuticular wax load, and n-alkanes profile were also performed. The results showed an inverse relationship between the percentage of herbivory and the index of sclerophylly. The leaves showed typical morphological and anatomical characteristics of xeric environments plants such as uniseriate epidermis and trichomes. Furthermore, it was also noticed a decrease in the overall thickness and the tissues according to the advancement of the successional stages. The histochemical revealed the presence of lipidic substances coating the epidermal layers, phenolics compounds stored in secretory structures, and starch in the mesophyll. The concentration of phenolics compounds indicating the difference from health leaves of plants between different stages of regeneration, but no difference when they were herbivored. The amount of cuticle wax did not change significantly with the successional stage. The profile of n-alkanes was characterized by the predominance of nonacosane (C29) and hentriacontane (C31). The C29 content decreases with the advancement of the successional stage, while the C31 content increases. All those attributes have a role to protect the plants to acclimate to the various environmental conditions of Caatinga.

Published: July 2021

ABSTRACT Studies that allow the estimation of evaporation in reservoirs represent an important action for the adequate management of water resources. Thus, this study aimed at estimating evaporation in the tropical reservoir Gavião, located in the municipality of Pacatuba, Ceará, Brazil, and to verify the effect of these estimates on the water availability of the reservoir using the VYELAS model. The results of Penman's methods and the Water Balance were compared with the values obtained from the hydrostatic pressure sensor, the most accurate. It was possible to verify that, in relation to the pressure difference method, all the conventional methods overestimate the evaporation in the reservoir. The method that presented estimates closer to those obtained by the pressure difference sensor was that of Penman, based on data from an onboard station in the lake, with a deviation of only 12%. The method of water balance also presented reliable results for monthly average. The two methods usually accepted in the evaporation calculation (water balance ignoring the infiltration; and Penman's method for meteorological station data on land distant from the lake) presented the most disturbing evaporation values significantly altering the water availability. The results of the VYELAS model showed that evaporated flows, estimated by several methods, exceeded the reference flow by up to 83%. The results demonstrate the great sensitivity of the estimate of water availability in relation to the evaporation rate in the lake.

ABSTRACT The intense anthropization in the lower São Francisco River and surrounding areas can lead to environmental degradation risks and, above all, makes the area more susceptible to soil erosion. This study aimed to identify and correlate the physical and chemical properties able to enhance erosive processes and slope instability in the watercourse margins of the lower São Francisco River, in Sergipe State, Brazil. To this end, disturbed and undisturbed samples of an Entisol-Fluvent soil were collected in the region, specifically in the city of Amparo de São Francisco. Physical (density, porosity, and texture) and chemical (pH, cation exchange capacity, base saturation, micro-, and macronutrients) analyses were performed. All physical properties and organic carbon contents were higher in the surface layers (Ap and AC) compared to the others. Organic carbon, phosphorus, and micronutrients had a negative correlation with soil density, showing higher contents and lower soil densities in the Ap and AC layers. The pedological characteristics of the evaluated soil layers are unable to provide soil resistance to water erosion.

ABSTRACT This study aimed to assess the physical, chemical, and sensory attributes of mango varieties grown under the organic farming. Fruits from ten varieties of mango grown under the organic system in the Chapada Diamantina region, BA, Brazil, were assessed. The following physical and chemical characteristics were assessed: fruit mass, pulp yield, pulp color (L*, C*, and h*), soluble solids (SS), titratable acidity (TA), total carotenoids, and ascorbic acid. The sensory acceptance test was performed with 50 consumers using the nine-point structured hedonic scale and the attributes acidity, sweetness, and firmness of the pulp were assessed using the just-about-right scale. Differences among the varieties of mango grown under the organic production system were observed for physical, chemical and sensory attributes. The varieties showed a percentage of pulp equal or above 60%, which makes them more suitable for processing. According to the PCA analysis, the characteristics soluble solids, total carotenoids, fruit mass, titratable acidity, h* and L* were considered the most important to differentiate the mango varieties evaluated. Ubá and Beta varieties had the highest levels of SS, while Favo de Mel was characterized by the highest values of TA and L*. The varieties Favo de Mel, Palmer, Surpresa, Juazeiro 2, Imperial and Joa had fruits with higher mass and h* values and the varieties Amrapali and Roxa Embrapa 141 had the highest levels of total carotenoids. Imperial, Palmer, Beta and Joa varieties were the most accepted for all sensory attributes.

ABSTRACT Morpho-agronomic characterization studies aiming at the discrimination and classification of lima bean accessions in relation to the centers of domestication and biological status have been of great importance for conserving the biodiversity of this species. For this purpose, researchers have widely used the multivariate analysis called discriminant analysis, which is not always capable of producing satisfactory results. Computational intelligence-based classifiers are additional tools for understanding complex classification problems. In this study, the objective was to test the use of the decision tree in the classification of lima bean according to the centers of domestication and biological status (cultivated and wild), based on eight phenotypic traits of the seed. Sixty accessions of lima bean from the Phaseolus Germplasm Bank of Universidade Federal do Piauí (BGP / UFPI) were evaluated, and classification was performed using two approaches: conventional statistics with discriminant analysis of principal components (DAPC) and computational intelligence through decision tree (DT). The results showed that the use of DT was efficient to identify patterns in the classification of lima bean accessions, due to its comprehensibility. Seed weight was one of the main descriptors used to explain the origin and diversity of the species. The results found will be useful for studies that involve the conservation of genetic resources, mainly for the maintenance of germplasm banks and in breeding programs. In addition, it is recommended to integrate machine learning algorithms in studies aimed at classifying lima bean.

ABSTRACT Using organic filters produced in local communities with low financial cost can reduce the environmental impacts caused by the disposal of untreated wastewater into receiving water bodies. In this study, the objective was to evaluate the efficiency of the filtration of swine wastewater (SWW) using banana stalk as an alternative material in an organic filter. SWW was applied to the organic filter and the filtered volume was converted into pore volume. Analyses of total solids, turbidity, color, total phosphorus, and total nitrogen were performed in the filter feed solution and effluent to evaluate treatment efficiency. Regression analyses were used to obtain equations in the estimation of the filtration performance in removing these variables from wastewater, with pore volume as an independent variable. The banana stalk filter did not remove total solids and color from the feed solution applied. Removal of 10–50% of SWW turbidity were obtained by the banana stalk. Banana stalk was highly efficient in removing nitrogen and phosphorus from SWW, reaching mean removals of 67% and 62%, respectively. In general, a banana stalk filter can be considered a promising alternative in the primary treatment of SWW.

A ÉTICA COTIDIANA DAS INTERRUPÇÕES EM TRAJETÓRIAS RELIGIOSAS PENTECOSTAIS
Authors: Bispo Raphael
Published: July 2021

O objetivo deste artigo é estudar os momentos de interrupções em trajetórias evangélicas no Brasil contemporâneo; ou seja, analisar os processos de suspensão, paragem, refluxo e (des)continuidade, ocorridos ao longo dos desdobramentos das vidas religiosas de pessoas convertidas ao pentecostalismo. Tendo como base teórico-metodológica a antropologia das emoções e das moralidades, o trabalho debruça-se sobre as biografias de três artistas brasileiras evangélicas. Entende-se, neste texto, que as interrupções são eventos propícios para a produção de dramas morais e emocionais, por meio de histórias que são contadas de distintas formas discursivas. Nesse sentido, o propósito é acompanhar de maneira pormenorizada as flutuações éticas e subjetivas frente às demandas mundanas e sagradas experimentadas por estas artistas, realçando suas ações para lidar com as incertezas e sofrimentos do cotidiano, através do manejo que fazem das palavras e do modo como narram seus períodos de instabilidade na fé.

Published: July 2021

Resumo A violência é um fenômeno sociocultural que viola direitos e acentua desigualdades sociais. Suas implicações são perceptíveis na vida cotidiana e na saúde da população. Sob o referencial teórico da interseccionalidade e da psicologia sócio-histórica, este artigo discute formas de violência produzidas na intersecção de gênero, raça e classe em uma comunidade periférica e em situação de alta vulnerabilidade localizada na cidade de Cubatão/SP, a partir do relato de quatro lideranças comunitárias. Os dados foram obtidos por meio de três pesquisas realizadas anteriormente e concomitantemente ao contexto da pandemia da covid-19, de junho de 2017 a novembro de 2020, extraídos mediante entrevistas e diários de campo para, depois, serem analisados segundo a Hermenêutica de Profundidade. Os resultados apontam para violências estruturais articuladas a raça, classe e gênero, expressas na inacessibilidade a condições dignas de moradia, alimentação e renda básica. A violência contra mulheres, destacada como resultado, aparece intermediada pelo Estado ou pelo tráfico organizado. Os dados sugerem que as violências são agravadas pela ineficiência da operacionalização das políticas públicas, no que tange à promoção do cuidado à população majoritariamente negra e pobre, indicando que a interseccionalidade é uma ferramenta essencial para a análise e o enfrentamento das desigualdades sociais.

The Ecological-Economic Zoning (EEZ) is a territorial management instrument, a king of territory organization in zones which indicate activities that consider its potentialities and fragilities. The research analyzed in an integrated way the landscape of Rio Preto’s watershed, located in the south of Goiás State (Brazil) with the objective of proposing a zoning which ally environmental preservation and socioeconomic development. From the landscape analysis, five zones were delimited: 1) zone of restrict use (32%), characterized by remaining vegetation areas, slopes with strong/very strong dissection and hydromorphic soils; 2) urban industrial expansion one (0.53%); 3) consolidated sugar-energy production zone (19.47%), area which a power plant and its respective areas of sugarcane crops are localized; 4) zones of agrosilvopastoral use I (18%), characterized for being favorable to grains cultivation, forestry and pasture; 5) agrosilvopastoral zone use II (30%), with the same characteristics of the previous zone, however with the possibility of expansion of sugarcane plantation. It was proposed the creation of a belt of preservation unities taking advantage of the mountains, besides establishing ecological corridors all over Rio Preto, which would result in an average deadline on the water production increase.

Published: July 2021

This article aims to discuss the spread of horizontal condominiums and planned neighborhoods in the city of Passo Fundo - RS, in the decade of 2010. It is assumed that the new real estate products redefine the processes of socio-spatial segregation, showing the dispersion of the classes of middle and high income for peripheral areas, traditionally occupied by the low-income population. The reframing of the periphery denotes the complexification of the intra-urban socio-spatial structure, indicating the emergence of new patterns of socio-spatial segregation, superimposed on the traditional center-periphery model, constituted in the 20th century. In this context, it is argued that it is possible to recognize ongoing common processes, characterized by significant disruptions with the previous logic of production of intra-urban space.

Replay and eavesdropping attacks threaten the information security that is held by smart healthcare devices. An authenticated key exchange method to provide cryptography sessions is the best way to provide information security and secure authentication. However, smart healthcare devices do not have sufficient computation to perform heavy cryptography processes due to the limitations of the embedded devices used. We propose an authenticated key exchange protocol based on a physical unclonable function (PUF). The proposed protocol aimed to countermeasure from replay and eavesdropping attacks. We designed our protocol with one handshake process and three authentication processes. We evaluated our proposed protocol using Tamarin Prover. From the results of the evaluation, our proposed protocol can exchange properties correctly between communication actors and is valid in proving each lemma in eavesdropping and replay attacks.

Authors: W.O. Wan Maznah , Kassim Nur ‘Ain , Din Zubir
Published: July 2021

Zooplankton community structure and seston fatty acid content in relation with water quality characteristics at selected sampling stations of Penang coastal waters were determined. Water and zooplankton samples were collected on five sampling occasions from July 2009 until April 2011. Zooplankton samples were collected by horizontal towing with plankton net (WP-2) and a fraction of the samples was used to get seston population for fatty acid analysis. Phylum Arthropoda dominated the sampling area with 78.80% of relative abundance, where Copepoda was the most abundant. Other phyla such as Chordata (9.10%), Cycliophora (6.12%), Actinopoda (2.08%), Rotifera (2.57%), Annelida (0.63%), Cnidaria (0.51%), and Chaetognatha (0.19%) were accounted in small abundance. Kuala Juru Station, which was highly impacted by human activities had the highest relative abundance and Jerejak Station (control station and considered to have low impact by anthropogenic activities) had the lowest relative abundance. Zooplankton diversity was quite low at all stations, might be due to large abundance of dominant taxa. The dominant fatty acid methyl esters (FAMEs) detected on seston consisted of SAFA (C16:0, C14:0, and C18:0), MUFA (C16:0, C14:0, and C18:0), PUFA (C18:2n6c and C20:5n3) and HUFA (C22:6n3 or DHA). Zooplankton community was influenced by food availability (phytoplankton, as measured by chlorophyll a and fatty acid composition in seston) and water quality.

Published: July 2021

Fusarium fruit rot caused by fusarium species pathogens can be considered a threat to economic loss. The use of synthetic antifungals to control the pathogens has failed to the development of resistance of pathogens. Previous studies reported that plant extracts may contain various bioactive constituents that are able to control pathogen growth. Hence, the aims of this study are to examine the inhibition activity of some plant fresh extracts on mycelial growth and morphological changes of Fusarium oxysporum, F. proliferatum, and f. solani, causal agents of Fusarium fruit rot. Aqueous extract of selected plants was evaluated for their inhibition activity against all the three fusarium pathogens under in vitro condition using poisoned food bioassay. Averrhoa bilimbi fruit extract demonstrated a highly significant effect against mycelial growth of the pathogens with fungal inhibition percentage of 80.51% for F. oxysporum, 61.28% for F. proliferatum and 58.97% for f. solani. The results showed that the highest formation of 100% extract has lowered the conidia concentration and germination percentage of F. oxysporum (35.43%), F. proliferatum (47.61%), and f. solani (38.67%) compared to the control. Significant shriveled mycelia were observed via scanning electron microscope (SEM) on the pathogens treated with a. bilimbi extract, indicating morphological changes occurred in the cell membrane compared to the control in which the mycelia were in normal form. This innovation, which can be prepared and applied at home, has the potential as an eco-friendly and a benign approach to control fruit rot pathogen.

Bone marrow concentrate (BMC) has been emerging as a promising regenerative source to accelerate cartilage regeneration in cartilage injuries and osteoarthritis. Though the number of stem cells in BMC is limited, BMC is rich in growth factors that promote stem cell differentiation and tissue regeneration. Despite of multiple reports available on the use of BMC for cartilage repair in humans and its use in clinical settings, only limited number of pre-clinical proof of concept studies have been reported in animal models. Hence, a systematic review focusing on the potential of BMCfor the treatment of cartilage defect in animal models has been conducted. The systematic search of literature using three popular databases, ISI Web of Knowledge, PubMed and Scopus, were conducted without year restriction. Fifteen (n = 15) studies were found appropriate and included in this review. All of the included studies were of different animal models with cartilage defect. 13 out of 15 studies reported that the usage of BMC gave the best outcome compared to other treatment methods. Most of the findings provided good scoring on the tissue repair and the histological outcome. However, most of the BMC group outcomes did not give a significant difference when compared with other interventions such as the addition of platelet rich plasma, erythropoietin, hyaluronic acid, transforming growth factor, autologous tissue implant, genetic modification or scaffoldings. In conclusion, the published studies do suggest that BMC could provide a better cartilage repair. However, more preclinical studies are required to provide definitive conclusions.

Subcutaneous insulin injection is one of the therapies in the treatment of diabetes mellitus. However, problems such as pain at the injection site and lipodystrophy present a challenge that will influence patient compliance. This study aims to develop and characterise buccal film formulations containing insulin, utilising the glucose-lowering and pharmaceutical properties of Aloe vera. Characterisation tests such as morphology, rheological measurement, pH value, mechanical properties, and permeation test were performed on the optimal formulation. Assessment of the glucose-lowering efficacy was performed using alloxan-induced diabetic rabbits. Composition of the final film formulation included 3% w/w sodium carboxymethyl cellulose, 40% v/v glycerol, 70% v/v Aloe vera, 0.5% w/v mannitol, 0.125% w/v aspartame, 0.125% v/v Tween 80 and 15.3 mg insulin. The drug content has been determined to be 56.77 ± 8.55%. The formulation shows a low variation in weight and thickness measurements and acceptable physicochemical properties, in addition to sustained drug release for 6 h. The final film formulation that combined insulin and Aloe vera was effective enough to reduce blood glucose levels compared to the negative control (p > 0.05), despite fluctuation in the blood glucose levels throughout the study, and did not show any enhancement in reduction compared to the insulin-only film. In conclusion, the developed buccal film formulation has the potential to be used as a vessel for the delivery of insulin. Nevertheless, further studies are required to ensure the stability of the insulin via buccal route and stabilisation of insulin within the formulation.

Improving the mechanisms for forecasting inflation is an important part of economic science. National central banks, which monitor and manage the dynamics of the price level in the economy, use and develop these mechanisms in practice. Scientists and bank analysts have developed an impressive variety of ways to obtain estimates of inflation expectations of professional economists and ordinary citizens, as well as models for predicting future inflation values. In the last ten years, big data obtained from the Internet has been increasingly used for nowcasting inflation expectations and forecasting price dynamics. In this article, using the methods of correlation and regression analysis, it is demonstrated the validity of measuring the inflation expectations based on queries in Google Trends. In addition, these data turned out to be a fairly good predictor of the CPI level with a one-month lag. And combining the traditional CPI with a one-month lag and query statistics gave the lowest forecast error of all the model specifications considered. The resulting model is more flexible than the classical methods of forecasting inflation, including by taking into account the psychological aspects of economic behavior.

The purpose of this paper is to develop a concept for managing the level of risk of disrupting the sustainable development of the enterprise. The research methodology is based on the system economic theory and the operational theory of risk management. A methodology is proposed for the study of the development and implementation of management decisions in the managerial subsystem, taking into account the identified risks of sustainable development of the enterprise at the intentional, expectational, cognitive and functional stages. Within the framework of these stages, the processes of goal setting, information collection, assessment of the existing environment and forecasting of changes in the enterprise, as well as the processes of implementing decisions are carried out. To shed light on the processes of identifying risk factors and developing appropriate anti-risk managerial impacts depend on the localization in the control object. When decomposing a control object, four types of localization are distinguished: an object subsystem, a process subsystem, a project subsystem, and an environmental subsystem. The implementation of managerial decisions, from the point of view of the object subsystem, can be limited by the high cost of the main production equipment and long life cycles of the finished product. When implementing the developed managerial solutions, there may be a redistribution of profit centers or a change in the way it is generated, which will lead to a change in the characteristics of the enterprise's process subsystem. In the project subsystem, an enterprise can achieve maximum effect by focusing its efforts on the introduction of innovative technologies. The speed of changes in the external environment of the enterprise becomes very high, so the role of forecasting the impact of these changes on the environmental subsystem of the enterprise increases, and applying this knowledge to develop managerial impact, on the one hand, and to adapt the enterprise to these changes, on the other. It is shown that by regulating and eliminating the imbalance in the preparation of managerial impacts, it is possible to reduce the level of risk in the implementation of such decisions.
Timbre Space Learning for Augmentation of Musical Audio Synthesizer Interfaces

Published: July 2021

Machine learning systems are increasingly being explored for potential applications in the design of creative tools. In particular, musical audio synthesis is one such domain in which these systems can lend to the development of alternative modes of user interaction by means of control spaces based on relevant sonic qualities, rather than traditional synthesis parameters. Although these alternatives effectively lower the barrier to entry to synthesis by obviating the systems-level knowledge required to use traditional parametric synthesizers, we note that with few exceptions, prior work has simply presupposed a general utility in simplified modes of control, or used quantitative efficacy metrics which sacrifice ecological validity for precise evaluation. Meriting further investigation are relevant questions regarding the lack of widespread adoption of such systems, and their relation to the experience levels, creative processes, and aesthetic values that motivate synthesists. Toward answering these questions, this work proposes a novel timbre space learning (TSL) system which uses a generative neural network model to learn mappings from low-dimensional control spaces to synthesis parameters, and an example application which augments a novel parametric synthesizer rather than serving as its primary mode of interaction. A primarily inductive analysis of qualitative and quantitative data from 20 synthesists across a range of experience levels indicates that, when presented with the option of a simplified mode of interaction, users generally give primacy to parameter spaces and seek systems-level understanding of how parameters relate to sonic quality. This work highlights a range of creative uses of TSL augmentation for discovery of new sounds, expressive modulations of parameters, and timbral transpositions. Further, thematic analysis of participant interviews suggests a range of musical aesthetic values and complex relationships to expertise which may have implications for the use of TSL systems.
