Authors: Verboloz Elena , Ivanova Marina , Demchenko Vera , Fartukov Sergey , Evona Nikita
Published: March 2020

Introduction. Rose hips are rich in macro- and micronutrients. Unfortunately, heat treatment destroys most nutrients. Ultrasonic technologies make it possible to reduce the drying time and lower the temperature regime. The research objective was to adjust ultrasound technology to rose hip production in order to reduce the loss of vitamins and improve the quality indicators of the dried product.

Study objects and methods. The research featured rose hips of the Rosa canina species collected in the south of Kazakhstan. This subspecies of wild rose is poor in vitamin C. Nevertheless, this shrub is extremely common in Russia and other countries of the Commonwealth of Independent States. The raw material was dried according to standard methods. One group of samples was treated with ultrasound, while the other served as control. Both groups underwent a sensory evaluation and were tested for moisture and vitamin C.

Results and discussion. The rose hips were dried in a combination steam oven with a built-in ultrasonic wave generator. The research revealed the following optimal parameters of the ultrasound drying process: frequency of ultrasonic vibrations – 22 kHz, processing time – 2.5 h, temperature in the combination steam oven – +56°C, initial moisture content – 30%. The resulting product met the requirements of State Standard. The loss of moisture was 57%. According to State Standard 1994-93, the initial moisture content should be 15% or less. Time decreased from 360 min to 160 min, and the initial moisture was 13%. The experiment confirmed the initial hypothesis that ultrasonic treatment improves the drying process by improving quality indicators and preserving vitamin C in raw materials using.

Conclusion. Ultrasound treatment during moisture removal from rose hips provides a resource-saving technology that fulfills an economically and socially important function.

This review is devoted to the description of chemical peculiarities of industrial oil crops cultivated (or prospective for cultivation) in Russia, which are stored in the VIR collection. Different crops have similar fatty acids biosynthesis pathways, but each species has its own individualities in the chemical composition of the oil and its genetic control. The diversity of oil crop chemical composition opens the possibility of its multipurpose utilization practically in all industrial segments. Sunflower, rapeseed, flax, mustard, camelina and safflower are cultivated in Russia as oil crops. Castor beans, perilla, lallemantia and noog are not cultivated on an industrial scale, but have original oil properties and are prospective for future cultivation. Hemp and poppy seeds contain oil valuable for food, but they are not widespread. Cotton and peanut oils are prospective for industrial purposes when early, already created varieties of these crops will be cultivated in Russia. Oil properties depend on the ratio of its basic fatty acids: saturated (stearic, palmitic) and unsaturated (oleic, linoleic, linolenic). As a rule, lauric, myristic and palmitoleic acids are determined in minor quantities. The oil of Brassicaceae crops also includes arachidic, eicosenoic, eicosadienoic, behenic, erucic and lignoceric acids. Fatty acids accumulation is influenced by growing conditions, though it has strict genetic control.

Published: March 2020

Introducción: Las condiciones dinámicas de los mercados demandan el estudio de la innovación empresarial. Con base en el estudio de la literatura de gestión, se ha propuesto que existe una influencia de los factores organizacionales de autonomía y disponibilidad de tiempo otorgado a los empleados en el nivel de innovación en la empresa.Método: Para probar esta suposición, se aplicó un instrumento cuantitativo elaborado a partir de la escala CEAI y la medida ENTRESCALE, considerando 144 observaciones en una empresa de servicios de transporte de pasajeros en el norte de México. Posteriormente, se realizó un análisis factorial exploratorio para verificar la validez de los constructos: el alfa de Cronbach para identificar su nivel de confiabilidad; y la técnica de regresión lineal múltiple, a fin de verificar el efecto de las variables independientes sobre la innovación.Resultados: El análisis factorial exploratorio y la medida del alfa de Cronbach respaldan la validez de constructo y la confiabilidad de los ítems que componen el instrumento de medida. Los resultados de la técnica de regresión lineal múltiple demuestran que solo la autonomía tiene un efecto con el nivel de innovación en el sector, por lo que se descarta que la disponibilidad de tiempo libre se relacione con la conducta innovadora.  Discusión o Conclusión: Los resultados contribuyen al desarrollo teórico de los constructos, e invitan a la reflexión sobre mejores prácticas empresariales que deriven en el desarrollo de una conducta innovadora en la empresa.
Factors that affect the experience of entrepreneurship in university students. A study in a private institution in Merida, Yucatan, Mexico
Authors: Barroso Tanoira Francisco Gerardo , Santos Valencia Raúl Alberto , López Ponce María Eugenia
Published: March 2020

Introduction: It is important to educate young university students for adapting to social, economic and environmental changes in the world. It is not to prepare them just to be employees, but entrepreneurs who could be leaders in their fields, creating jobs and improving people’s quality of life. For this, there are entrepreneurship programs based on high impact project incubation, but there is still the risk of dropping out. For this, the objective of this study was to identify the factors which positively and negatively affect the entrepreneurship experience in university students, from the perception of young students who have already had an incubated project. Method: The study approach was qualitative, with an exploratory and descriptive type and a non-experimental and transverse design. The participants were twenty students who have already had an incubated project, registered at the Tax Agency and legally constituted as an enterprise, besides of their involvement in entrepreneurship activities along their education process at the institution. All of them were from a private university situated near Mérida city, Yucatán, in the Southeast of México, acknowledged for its entrepreneurship education as well as for its incubation and acceleration processes. A semi-structured interview guide was used, conducted by the researchers.  Results: The factors that positively affect students to become entrepreneurs are personal ones, such as intrinsic motivation and the opportunity to be creative and dedicate to an interesting activity, accepting the risks. This is reinforced by the help of the coach, attendance to events, lectures and workshops, as well as constant feedback from expert panels. The ones which negatively affect the entrepreneurial experience are mainly external, such as the lack of monetary funds for living while the project is incubated, because when there are monetary resources, they are just for the project. There are also other internal factors such as the fear for making mistakes and the lack of experience for starting a business. Conclusions: The factors which prevent the entrepreneurship development depend on each participant more than in the method. The student must have time for the project and to continue his courses without the need to search for a job for making a living along the incubation. Then, there must be strategies to guarantee time and monetary resources so students don’t have distractors which could become entrepreneurship barriers. Besides, university study plans must be improved for enhancing creativity, innovation and entrepreneurship from initial stages. Incubators must be places for enhancing insertion of new enterprises in nets and create university clusters.

Authors: Jenicek P. , Svehla P. , Zabranska J. , Dohanyos M. , Vondrysova J.
Published: March 2020

The new biological methods of separate reject water treatment became progressive tools to optimization of nutrient removal in wastewater treatment. The method of nitritation and denitritation is one of them. The drawback of the method in comparison with technologies based on autotrophic deammonification is higher requirements for organic substrate. The possibility to suppress the drawback is the use of primary sludge as internal carbon source for denitritation. The experience with such design of separate reject water treatment process is described. The presented results confirm the possibility of efficient, stable and economical removal of nitrogen from reject water by separate biological treatment using nitritation and denitritation process and using primary sludge as the additional carbon source.
Two-Stage High Rate Digestion and Phosphorus Recovery
Authors: Heinzmann Bernd , Engel Gerd
Published: March 2020

Improved sludge disposal can be achieved by intensified digestion. With the reduction of the hydraulic retention time and by higher dried solid matter of the sludge, the volume load increases. In the WWTP Waßmannsdorf the digestion could be intensified by higher DSM of the mixed sludge. Furthermore, by application of a two-stage high rate digestion process in first tests in 2002 a degree of degradation of around 50 % organic DSM was achieved. A high organic volume load of around 3.2 kg/m3 per day and a degradation rate of around 50 % were results of first pilot plant trials over a time period of more than 3 month with the two-stage high rate digestion process without usage of a rotating membrane disk filter and showed a stable and safe operation. By using the RMD in the next phase of the pilot plant trials more water will be extracted from the digested sludge and so the digestion time can be extended and the organic volume load can be increased, in order to achieve further improvements (degree of degradation and improved gas production). Furthermore, there is a high potential for P-recovery in the highly digested (mineralised) sludge. First trials show in principle that precipitated MAP could be separated by using the hydro-cyclone technique.
Downstream implications of ultra-low flush WCs
Authors: Littlewood K. , Memon F.A. , Butler D.
Published: March 2020

This paper examines some of the issues associated with the impacts of water demand management on the drainage network. In particular, it is argued that with the advent of lower water use WCs, much lower volumes and flow rates will be available to transport gross solids in sewers. The paper reports some of the results of a study to evaluate the performance of one such ultra-low flush WC in terms of limiting solids transport distance. It was found that the ultra-low flush toilet performed as well as a conventional WC, but only when connected to a 50mm diameter drainage pipe. The implication is that for best use of this technology, and other innovative devices, new building drainage design rules will need to be devised.
First estimation of occurrence and fate of organic substances in combined sewer systems with pollution load simulations
Authors: Welker A.
Published: March 2020

Emissions of selected organic substances from a hypothetical combined sewer system are calculated by pollution load simulation. The results are subsequently discussed. First, representative concentrations of chemical oxygen demand (COD), ammonium (NH4-N) and eight selected organics (polycyclic aromatic hydrocarbons (PAH), isoproturone, Di(2-ethylhexyl)phthalate (DEHP), ibuprofen, 17-ß-estradiol (E2), 17-a-ethinylestradiol (EE2), ethyl-enediamine tetraacetic acid (EDTA), nitrilo triaceticacid (NTA)) in dry weather flow, surface runoff and effluent of WWTP in combined sewer systems are stated based on a literature survey. The second part of the paper presents pollution load simulations and first calculations of possible dis-tributions of organics in combined sewer systems for a hypothetical catchment. Different scenarios of annual discharge loads of main emission matrices of the catchment (waste water treatment plant (WWTP) effluent and combined sewer overflow (CSO)) are compared to determine significant dis-charge points. The results of the pollution load simulations show that generally discharges from the WWTP dominate the total emissions of combined sewer systems. Nevertheless, emissions from CSOs are not negligible in some cases (e.g. for estradiol). In summary, the results give first indications about possible strategies to reduce pollutant emissions from combined sewer systems. The paper also formulates recommendations for the selected organic compounds.

Authors: RAMOS NERY Maria Clara , PEREIRA Juliana  Oliveira , AMARAL Patricia Guerreiro do
Published: March 2020

Este artigo é resultado de observação de campo em turmas de EJA. Nossas questões investigativas são: Quais as mediações pedagógicas possíveis para o efetivo ensino na Educação de Jovens e Adultos - EJA? Estão livres de impasses e contradições? O objetivo geral foi abordar os impasses e as contradições existentes no contexto das escolas da Educação de Jovens e Adultos (EJA), que no âmbito de nossa realidade está a perder espaço significativo de inserção social e de posse do conhecimento para aqueles que em tempo "regular" de suas vidas, não puderam dar seguimento em seus estudos. A atividade de observação de campo foi realizada numa escola estadual de Cruz Alta/RS., onde se verificou práticas didático-pedagógicas realizadas numa turma de Ensino Médio  – T9, em  aula de Matemática e em aula de História, com  distintas mediações pedagógicas. Teórico-metodologicamente laborou-se com estudo de caso, buscando, responder adequadamente às nossas questões investigativas e com autores que investigam a questão EJA no Brasil, os quais estão citados no texto. Como resultado pôde-se, constatar duas situações distintas de mediação pedagógica: uma prática de ensino-aprendizagem alicerçada na didática tradicional (bancária), e outra prática alicerçada no contexto de vida dos alunos. Como resultado do trabalho investigativo: constatamos ser acanhado o número de professores preparados para ministrar aula em turmas de EJA, dada sua especificidade, sendo o processo de mediação pedagógica embasado em decisão pessoal do professor, bem como apuramos rara capacitação dos professores para o exercício de seu trabalho com alunos da EJA, gerando impasses e contradições.
Práticas de Saber-Poder entre Pobreza e Negligência que se Configuram na Institucionalização da Infância
Authors: Rosa Assis de Oliveira Thiago , Barbosa da Silva Roberta
Published: March 2020

Objetivamos problematizar o conceito de negligência no âmbito familiar, jurídico e social como motivo para o acolhimento institucional de crianças e adolescentes no estado do Rio de Janeiro, a partir de dados divulgados pelo Ministério Público do estado do Rio de Janeiro no Módulo Criança e Adolescente – MCA. Os dados analisam os índices de acolhimento institucional realístico em todo o estado, onde ficou constatado que desde sua primeira edição em 2008 até o ano de 2017, a negligência é apontada como a maior causadora dos acolhimentos, além, de ser apresentada como a maior das violações de direitos. Apresentamos um breve percurso legislativo do código de menores até o estatuto da criança e do adolescente, bem como, os desafios atuais desta nova legislação. Para contextualizar estas problematizações recorremos ao filósofo Michel Foucault.
"Para quem serve esse diagnóstico?'': uma interlocução entre o psicodiagnóstico e a psicanálise
Authors: Flores Oliveira Crislayne , Cabral Samico Fernanda
Published: March 2020

A psicanálise, atualmente, encontra um lugar profícuo no campo universitário, notadamente nos cursos de graduação de psicologia. Dessa maneira, o presente artigo é efeito de algumas inquietações advindas de dois campos de saber: o psicodiagnóstico e a psicanálise. Pretendemos dar partida à ação de se interrogar quais os benefícios do diagnóstico para aquele que o requer. Em uma atualidade em que a patologização dos indivíduos se tornou banalizada, a procura por diagnósticos é bastante comum e cabe problematizarmos a nomeação dos sofrimentos em parâmetros de normalidade e doença. Pretendemos, em última análise, sustentar a argumentação que o aluno de psicologia, ao entrar em contato com a noção de diagnóstico em psicanálise e sua ética, pode ter ferramentas cruciais para problematizar de forma positiva seu trabalho de psicodiagnóstico e adquirir uma postura que o salvaguarde de um mau uso de tal instrumento.
Diagnostic Value of Assessment of Serum Cortisol, Hepcidin and Thyroid Hormones Levels in Neonates with Late-Onset Sepsis
Authors: Hagag Adel A. , El Frargy Mohamed S. , Yonis Reham L. , Al-Ashmawy Ghada M.
Published: March 2020

Background:

Neonatal sepsis is a clinical syndrome characterized by symptoms and
signs of infection in the first twenty-eight days of life. Serum thyroid, cortisol and hepcidin are affected
by neonatal sepsis.

Aim of the work:

The aim of this study was to assess the diagnostic value of serum thyroid hormones
including free triiodothyronine (free TT3) and free tetraiodothyronine (free TT4), serum cortisol
and hepcidin levels through comparison of their concentrations between normal neonates and
neonates with high probable late-onset sepsis.

Patients and Methods:

This case-control study was carried out on 40 neonates with suspected high
probable late-onset neonatal sepsis based on clinical and laboratory finding who were admitted to
NICU of Pediatric Department, Tanta University, Egypt in the period from April 2017 to May
2019 (group I) and 40 healthy neonates matched in age and sex as a control group (group II). For
patients and controls, blood culture, highly sensitive C-reactive protein (H-s CRP), serum hepcidin,
serum cortisol and thyroid hormones levels including free TT3 and free TT4 were assessed.

Results:

There were no significant differences between studied groups regarding weight, gestational
age, sex and mode of delivery. H-s CRP, serum cortisol and hepcidin were significantly higher
in group I than group II while serum-free TT3 and free TT4 were significantly lower in group I
compared with controls (group II). There was significantly lower H-s CRP, serum hepcidin and cortisol
and significantly higher serum-free TT3 and free TT4 in group I after antibiotic therapy compared
to the same group before treatment while there were no significant differences between
group I after antibiotic therapy and control group (group II) regarding the same parameters. There
was a significant positive correlation between H-s CRP and serum hepcidin and cortisol in group I
while there was a significant negative correlation between H-s CRP and free TT3 and free TT4.
ROC curve of specificity and sensitivity of H-s CRP, serum hepcidin, cortisol, free TT3 and free
TT4 in the prediction of neonatal sepsis shows that serum hepcidin had the highest sensitivity and
specificity with 95% and 90% respectively followed by serum cortisol, H-s CRP, free TT3 and lastly
free TT4.

Conclusion and recommendations:

Neonates with high probable sepsis had significantly higher
serum cortisol and hepcidin and significantly lower free TT3 and free TT4 compared with healthy
neonates. These findings may draw our attention about the use of these markers in the diagnosis of
neonatal sepsis which can help in early treatment and subsequently better prognosis.
Prostate Cancer Detection in Screening Using Magnetic Resonance Imaging and Artificial Intelligence
Authors: Nelson Chris R. , Ekberg Jessica , Fridell Kent
Published: March 2020

Background:

Prostate cancer is a leading cause of death among men who do not participate in a screening programme. MRI forms a possible alternative for prostate analysis of a higher level of sensitivity than the PSA test or biopsy. Magnetic resonance is a non-invasive method and magnetic resonance tomography produces a large amount of data. If a screening programme were implemented, a dramatic increase in radiologist workload and patient waiting time will follow. Computer Aided-Diagnose (CAD) could assist radiologists to decrease reading times and cost, and increase diagnostic effectiveness. CAD mimics radiologist and imaging guidelines to detect prostate cancer.

Aim:

The purpose of this study was to analyse and describe current research in MRI prostate examination with the aid of CAD. The aim was to determine if CAD systems form a reliable method for use in prostate screening.

Methods:

This study was conducted as a systematic literature review of current scientific articles. Selection of articles was carried out using the “Preferred Reporting Items for Systematic Reviews and for Meta-Analysis” (PRISMA). Summaries were created from reviewed articles and were then categorised into relevant data for results.

Results:

CAD has shown that its capability concerning sensitivity or specificity is higher than a radiologist. A CAD system can reach a peak sensitivity of 100% and two CAD systems showed a specificity of 100%. CAD systems are highly specialised and chiefly focus on the peripheral zone, which could mean missing cancer in the transition zone. CAD systems can segment the prostate with the same effectiveness as a radiologist.

Conclusion:

When CAD analysed clinically-significant tumours with a Gleason score greater than 6, CAD outperformed radiologists. However, their focus on the peripheral zone would require the use of more than one CAD system to analyse the entire prostate.
EU IVDR Regulatory Changes: An Overview of Requirements in (EU) 2017/746
Authors: Nayak Shashank , Venkatesh M.P. , T.M Pramod Kumar
Published: March 2020

IVDR is the new regulatory basis for placing IVDs in the market, making them available
and putting them into service in the European market. EU IVDR regulation is much bigger
than the impact of EU IVDD, which is a bold statement to make, considering the significant industry-
wide impact as it presents challenges to the manufacturer. Rather, it is largely a revision
that contains guidance on how to fulfill the existing IVDD requirements. IVDR focused on the
IVD-specific provisions therein regarding classification, performance evaluations, clinical data,
conformity assessments and notified bodies. IVDR presents enormous change to the IVD industry,
not only because it needs a significant change in technical documentation and Quality management
system, but also because it changes the relationship with the economic operator and their responsibilities.

Published: March 2020

Background:

Lithium-rich layered materials with high discharge capacity are regarded as
one of the most promising cathodes for lithium-ion batteries (LIBs). However, they have been suffering
from rapid voltage fading and poor rate performance, which impede their practical application.

Methods:

Herein, Li1.2Mn0.6Ni0.2O2 with layered structure was successfully prepared by the ultrasonic
dispersion-assisted chemical reduction. X-ray powder diffraction (XRD), X-ray photoelectron
spectroscopy (XPS), scanning electron microscope (SEM), transmission electron microscope (TEM)
and electrochemical measurements were used to characterize its microstructure and electrochemical
properties.

Results:

The secondary particles of an as-prepared micro/nanostructured sample consist of irregular
and sheet-like rectangular blocks. Electrochemical results show that the initial charge and discharge
capacity within 2.0~4.8 V is 337.5 mA h g-1 and 236.9 mA h g-1 at 0.2C (1C = 200 mA g-1). The subsequent
discharge capacity is stabilized at about 210 mA h g-1 for more than 100 cycles. When the
current density is increased to 2C, the cycling columbic efficiency is maintained at 99.3% after 100
cycles.

Conclusion:

Thus, the Li1.2Mn0.6Ni0.2O2 cathode material prepared by ultrasonic dispersion-assisted
chemical reduction has a promising application in LIBs with high energy density and long cycle life.

Purpose of the study — to evaluate bone density at the femur fracture site with local introduction of preparations based on etidronate lanthanide ions and calcium in the experiment. Materials and Methods. The experiment included 45 male rats divided into three comparable groups equal in quantity. The experiment in control group was performed without stimulation of bone formation, preparation based on etidronate lanthanide ions and calcium were introduced to the animals of the first group and preparation containing etidronate and calcium (without lanthanide ions) were used in the second group. Preparation was introduced twice at the site of femoral fracture in the study groups of animals. The authors performed daily clinical monitoring and measured the density of the cortical bone at the fracture site using computer tomography. Results. Earlier support on the operated limb was observed after introduction of etidronate lanthanide ions and calcium. In the respective study group after introduction of the preparation the authors reported statistically significant 20% higher cortex density at earlier terms in contrast to the control group, and 24% higher density as compared to group with introduction of etidronates and calcium (without lanthanide ions). By day 30 cortical plate density in the group with introduction of preparation based on lanthanide ions was statistically significantly higher at 37% as compared to two other groups. Conclusion. The authors observed a positive effect of studied preparations on bone regenerate formation in rats. Data of the present research allows to conclude that periosteal introduction of preparations based on etidronate lanthanide ions and calcium at the osteotomy site provides formation of a cortical plate with improved density properties, and normalization of density indicators in the present group occurred in earlier terms that in the group with preparation based on etidronates and calcium (without lanthanide ions).

Published: March 2020

The study objectives were to determine the extent to which the sarcoplasmic proteome explains variations in aged pork loin star probe value. Pork loins (n=12) were categorized by differences in star probe at 21 d post mortem from a larger set of loins. Loins were categorized into low star probe (LSP) group (n=6; star probe<5.80 kg) and high star probe (HSP) group (n=6; star probe>7.00 kg) based on 21-d star probe value with inclusion criteria of marbling score (1.0–3.0) and 24-h pH (5.69–5.98). Quality traits were measured at 1-, 8-, 14-, and 21-d aging. Desmin and troponin-T degradation, peroxiredoxin-2 abundance, calpain-1 autolysis, and sarcomere length were determined. Two-dimensional difference gel electrophoresis and mass spectrometry were used to identify proteins that differed in abundance due to category. Star probe values were lower (P<0.01) in LSP at each day of aging compared with HSP. Greater pH values were observed (P<0.05)in LSP compared with HSP at each day of aging. Marbling score was greater (P<0.05) in LSP compared with HSP at each day of aging. Greater (P<0.05) desmin and troponin-T degradation was detected in LSP chops at 14- and 21-d aging and 8-, 14-, and 21-d aging, respectively. Greater (P<0.05) sarcomere length was determined in LSP compared with HSP at 1-,8-, and 21-d aging. Sarcoplasmic proteins from HSP chops had greater abundance (P<0.10) of metabolic and regulatory proteins, whereas the LSP chops had greater abundance (P<0.10) of stress response proteins. Star probe values were affected by pH, marbling score, protein degradation, sarcomere length, and sarcoplasmic proteome.
El desarrollo de los invernaderos en Zacatecas. Entre el auge y el abandono
Authors: Hernández Suárez José Luis
Published: March 2020

Objetivo: conocer las causas del impulso gubernamental a la producción en invernaderos en Zacatecas, México, durante el periodo 2000-2012, y del menor incentivo que tuvo en las gestiones públicas sucesivas, para valorar, desde la perspectiva del ciclo de las políticas públicas, las expectativas de fomento del gobierno al crecimiento y mejora de esa forma importante de producción agrícola, mediante la corrección de errores en el diseño e implementación de la política pública en cuestión.Método: con base en la perspectiva del ciclo de las políticas públicas, información oficial, investigaciones académicas y entrevistas con actores clave, se analizó el número de invernaderos y de superficie activa e inactiva, dividiéndolos de acuerdo con el tamaño en hectáreas.Resultados: la política de invernaderos en México fue diseñada para un perfil de productor de tipo empresarial, cuyo éxito depende del capital, capacidades y habilidades, antes que de los apoyos gubernamentales. Dicho perfil fue tomado como modelo cuando el gobierno federal decidió impulsar el crecimiento económico basado en el sector empresarial, pero existen productores que sufrieron más dificultades para permanecer en ese tipo de agricultura.Limitaciones: una parte de los datos estadísticos utilizados no tiene el año al que corresponden, por lo que se vuelve difícil precisar el análisis.Principales hallazgos: en Zacatecas se observa un auge del número de invernaderos, pero también una alta proporción en condición de inactividad, con un predominio de unidades menores de una hectárea.

Published: March 2020

Perkasa pangasiid (Pangasianodon hypophthalmus) is a superior catfish selected by the family that has been released by the Minister of Marine and Fisheries as aquaculture fish which has a selection response of 38.86 %. Genetic quality improvement to accelerate growth can be done through selection activities. The performance test of the Siamese catfish from the selection (Perkasa strain) compared to the non-selection strain (local strain) originating from the farmer. The purpose of this study was to compare the productivity of selection and non-selection Siamese catfish cultivation maintained in a net pond. The initial seeds of the test fish were 3.76 g to 3.79 g with a total length of 2 inches to 3 inches kept in a net pond measuring 3 × 5 × 1.25 m.

A libertação dos oprimidos
Authors: Souza Kelma Fabíola Beltrão de
Published: March 2020

Este texto teve por objetivo refletir sobre o conceito de liberdade e libertação, a partir do que disse Paulo Freire em Educação como Prática da Liberdade (que ele chama de “introdução à Pedagogia do Oprimido”) e Pedagogia do Oprimido. A nosso ver, como o conceito de liberdade foi especialmente sugestionado por Erich Fromm, trouxemos para o debate a sua problematização. Identificamos que Freire, de certa forma, vai preterindo a ideia de liberdade, usada inicialmente para significar as ideias de Fromm, e se volta especialmente às ideias marxistas. Isso demonstra o investimento de Freire na libertação dos oprimidos, onde reside quase todo propósito de sua pedagogia, cuja principal obra, Pedagogia do Oprimido, está completando cinquenta anos.

LA SEXUALIDAD EN ENTREDICHO: NUEVAS NEGOCIACIONES DEL SIGNIFICADO DE SER MUJER EN EL DEPORTE DE ALTO RENDIMIENTO
Authors: Donoso Perez Belen , Reina Giménez Amalia , Álvarez-Sotomayor Posadillo Alberto
Published: March 2020

Esta pesquisa tem como objetivo, por um lado, explorar as percepções das atletas sobre como são avaliadas pelo seu ambiente social em relação à feminilidade e sua orientação sexual, para vincular-se a uma prática esportiva de alto desempenho e, por outro, analisar a visibilidade e aceitação da homossexualidade no contexto esportivo, tanto pelos atletas como pelos agentes sociais ao seu redor. A metodologia foi qualitativa. Foram feitos cinco grupos focais nos quais participaram 46 mulheres praticando futsal, handebol, vôlei, atletismo e natação. Os resultados mostram que as atletas apresentam um discurso de resistência contra o estereótipo da "Maria-João" o "sapatão" que, verificamos, ainda está em vigor na imaginação coletiva. Embora os avanços sociais sejam percebidos nesse sentido, a homossexualidade permanece estigmatizada e ainda persistem as formas de rejeição cognitivo-afetiva em parte da sociedade espanhola.
The impact of digitalization on the internationalization propensity of Italian family firms
Authors: Quarato Fabio , Pini Marco , Positano Edoardo
Published: March 2020

Although the role of innovation and digitalization represents critical factors to succeed in the international context, there is a lack of empirical evidence on how they impact on the international propensity of family firms. We address this gap investigating to which extent family firms adopt digitalization tools and their effect on export-orientation, as well as whether the innovation can play a boosting role for family decision makers. Based on a survey of 2,500 Italian firms carried out in 2015 by Italian Chambers of Commerce, we find that family firms face more difficulties in undertaking digital transformation decisions, since they can weaken family SEW endowment but digitalization solutions enable the international propensity of family firms, bridging the gap with their non-family counterparts. Theses results advance the current debate on risk preferences of family firms, taking into account firm conditions, in terms of digitalization and innovation equipment, under which family owners make strategic decisions.

Published: March 2020

In this paper two partially complementary formulations of the simple phenomenological Kachanov-Rabotnov continuum damage constitutive model are presented. The models are based on a consistent thermodynamic formulation using proper expressions for the Helmholtz free energy or its complementary form of the dissipation potential. Basic features of the models are discussed and the behaviour in tensile test and creep problems is demonstrated.

Objective

This study aimed to identify the mediation effects of health locus of control (HLC) and hope between stroke patients’ social support and self-management.

Methods

A cross-sectional study was conducted. A total of 300 Chinese stroke patients were recruited by convenient sampling from the acupuncture department of two Chinese Traditional Medical Hospitals in Tianjin Province from June to September 2018. The self-report questionnaires include Social Support Assessment Scale, Herth Hope Index, Mental Health Locus of Control Scale, Stroke Self-management Behavior Scale, and personal information questionnaires. All the survey data were entered in Excel and analyzed using the SPSS 24.0 program. Mediation was tested with Bootstrapping in AMOS 23.0 program.

Results

The result showed that internal health locus of control (IHLC), chance health locus of control (CHLC) and hope were the mediators between social support and self-management. The direct, indirect, and total effects of social support on self-management behavior were 0.306 P < 0.01), 0.109 (P < 0.01), and 0.415 (P < 0.01), respectively.

Conclusions

Social support can directly influence self-management, and it can also indirectly influence self-management through IHLC, CHLC, and hope.
Library and Information Science Vis-À-Vis Web Science in the Light of the OECD Fields of Science and Technology Classification
Authors: Grabowska Marta
Published: March 2020

Aims: The paper focuses on the methodological frames of Library and Information Sciences vis-à-vis Web Science in the light of the OECD Fields of Science and Technology Classification. The roots of Library Science and Information Science in Humanities and Social Sciences are described. The technological revolution which took place during and after World War II enabled the development of a new mathematics- and engineering-oriented environment for information. On this basis such new research areas like Web Science emerged. It led to a change towards an interdisciplinary character of Information Science. Method: The OECD Fields of Science and Technology Classification was analysed from the point of view of the Library and Information Science’s place in this classification.

Solutions: In the OECD Fields of Science and Technology Classification Library Science has its independent place within Social Sciences while Information Science is dispersed between three main sections. It confirms the interdisciplinary character of Information Science and sets up its name as a superior covering traditional Information Science and all of new mathematics- and engineering- based research areas dealing with information. Although the name Web Science is not mentioned in this classification, we can assume that it is a sub-discipline of Information Science in the light of the OECD classification. Polish implications are mentioned.
