Published: January 2021

The main objective of this study was to assess the care of children and child offenders in particular under the Child Rights Law (CRL) of Lagos State in some selected custodial institutions. The study adopted a triangulation approach to collect both primary and secondary data from four purposefully selected Special Correctional Centres between 7th July and 30th September, 2013. Social welfare officers in charge of these custodial institutions were interrogated. Findings revealed that only two Special Children’s Centres had child offenders. Other results include poor living conditions, inadequate recreational facilities, regular visits from parents/guardians and formal and informal education as stipulated in section 52 and 224 (1) of CRL respectively. Major challenges were poor data base, poor security of the premises, shortage of skilled staff and lack of funds and awareness of the services of custodial institutions. Organisation of awareness campaigns, recruitment and capacity building for staff, improvement of living conditions to meet the CRL standard, among others, are recommended.

Abstract

Stunting, a condition of major nutritional deficiency in Indonesia, is a nutritional problem during the first 1000 days of life, from the first day of pregnancy to the age of 2 years. Many studies link poor environmental sanitation to the incidence of stunting. To improve environmental sanitation, the Government of Indonesia issued Minister of Health Regulation No. 3 of 2014 in the form of a Community-Based Total Sanitation (STBM) program. STBM is carried out in 5 pillars, namely stopping open defecation (SBABS), washing hands with soap (CTPS), managing drinking water and household food (PAMMRT), protecting household waste (PSRT), and protecting household liquid waste ( PLCRT). This study aims to analyze the knowledge of the successful implementation of the STBM program with the risk factors for stunting of children under two years of age in the city of Palembang. This type of research, analytic observational, and cross-sectional study design. Primary data were collected directly using a questionnaire. The average level of knowledge about STBM pillars and risk factors for stunting is in a good category. There is a significant relationship (p-value <0.05) between knowledge of SBABS and risk factors for infection in children, environmental sanitation, and availability of clean water; CTPS with risk factors for infection in children and the availability of clean water; PAMMRT with risk factors for infection in children and the use of biomass fuels; PSRT with risk factors for infection in children and environmental sanitation; and PLCRT with risk factors for infection in children, environmental sanitation and availability of clean water. It is concluded that the pillars of PSRT and PLCRT have the most influence on the risk factors for stunting in Palembang City.

Financial Condition of Local Government in Poland vs StructuralReforms of Municipal Government in Scandinavian States
Authors: Osiński Joachim , Zawiślińska Izabela
Published: January 2021

The authors have undertaken an analysis of the phenomenon of debt of local government units in Poland. It is a dynamic phenomenon, which affects vast majority of municipalities and districts. A barrier to debt expansion has been established in the form of the Individual Debt Index (IOI), which has been in place since 2014 and its new elements entered into force on 1 January 2020. The structure of the index is intended to allow regional accounting chambers (RIO) to control the process and prevent its progression. The authors indicate, however, that the main problem for local self-government units is insufficient own income, which forces them to increase the pool of funds transferred from the central budget to self-governments in the form of grants and subventions and to look for various forms of loans for their activities. Using the experience of the Scandinavian countries, the authors propose to start territorial and resource consolidation reforms of small local government units – municipalities and districts. The aim is to facilitate better use of endogenous resources of territorial self-government units and use of economies of scale related to local economy and social resources. This should result, as in Scandinavia, in the development of public entrepreneurship, higher social efficiency and effectiveness, and stabilisation of the income of individual units. After more than 20 years of operation, small local government units in Poland have become structurally and functionally obsolete and do not guarantee modern development of local communities.
Selected areas of female MPs presence in the Polish Sejm in 1991–2018 – quantitative aspects
Authors: Pająk-Patkowska Beata
Published: January 2021

The article analyzes representation of women in the Polish Parliament (Sejm) in 1991–2018, a period which corresponds to 8 terms of office. The analysis excludes the Sejm of the 10th term of office (1989–1991) due to the specific nature of the election and a different mode of its operation in the period concerned. Areas of activity and female MP participation were defined based on documents that regulate the working of the Sejm. The hypothesis assumes that main bodies and institutions of the legislative branch (Presidium, Marshal, parliamentary committees) show a disparity between the number of male and female MPs. Another hypothesis is that women are more active in committees that deal with issues stereotypically associated with women, such education and health. The study involved document and statistical analyses to compare data pertaining to the activity of male and female MPs. Research materials comprise data available at sejm.gov.pl (archives of eight terms of office). It is worth emphasizing that the website is a reliable source of information. A large part of resources has been digitized which facilitates access to research materials.
The image of the “Russian hacker” and cyberphobia of the “digital environment”
Authors: Sidorov Viktor Aleksandrovich
Published: January 2021

The “digital environment” is perceived as a new situation in the political consciousness of the society, as well as a source of xenophobia in politics. In the context of political uncertainty in the world, journalism is becoming a vehicle for spreading cyberphobia – a new type of social fear. Cyberphobia is understood as a natural reaction of public consciousness to the intensification of new types of crimes against the individual and society with the use of “digital” technologies. The new informational reality has predetermined cyberthreats that appeared in the media leading to the most dangerous social phobia. This, for instance, has been combined with the idea of the “Russian hacker” and his personification as the world Evil.
Long noncoding RNA FTX ameliorates hydrogen peroxide-induced cardiomyocyte injury by regulating the miR-150/KLF13 axis
Authors: Zhang Yamin , Fan Xiaoying , Yang Hua
Published: January 2021

Background

Myocardial reperfusion is an effective therapy for acute myocardial infarction (AMI). However, ischemia/reperfusion (I/R) injury following myocardial reperfusion is a significant limitation for AMI treatment. Five prime to Xist (FTX) was recognized as a biomarker of multiple diseases, including heart disease. However, the molecular mechanism of FTX in I/R injury is unclear.

Methods

Cell viability was evaluated by using cell counting kit-8 (CCK-8) assay. Apoptosis was analyzed by using a caspase-3 activity detection kit and flow cytometry. The expression of FTX, microRNA (miR)-150, and Kruppel-like factor 13 (KLF13) was measured by quantitative reverse transcription-polymerase chain reaction (qRT-PCR). The interaction of miR-150 and FTX or KLF13 was confirmed by a dual-luciferase reporter and RNA immunoprecipitation (RIP) assays. Protein expression of KLF13 was examined by Western blot. The role of FTX was detected in I/R-injured heart tissues in vivo.

Results

Hydrogen peroxide (H2O2) induced cardiomyocyte injury by decreasing cell viability and expediting cell apoptosis. However, FTX alleviated cardiomyocyte injury by promoting cell proliferation and restricting cell apoptosis of H9C2 cells that were treated with H2O2. In addition, we discovered that FTX directly interacted with miR-150, while KLF13 was a target of miR-150. Rescue experiments showed that miR-150 neutralized the FTX-mediated promotion of cell progression and restriction of cell apoptosis in H9C2 cells treated with H2O2. KLF13 knockdown restored the effect of miR-150 on increased proliferation and decrease in apoptosis in H2O2-treated cardiomyocytes. Furthermore, FTX enhanced the expression of KLF13 protein through interaction with miR-150. Upregulation of FTX repressed apoptosis in I/R-injured heart tissues in vivo.

Conclusion

FTX relieves H2O2-induced cardiomyocyte injury by increasing KLF13 expression via depletion of miR-150, thus providing a novel therapeutic target for the alleviation of I/R injury.
MHD squeezed Darcy–Forchheimer nanofluid flow between two h–distance apart horizontal plates
Authors: Rasool Ghulam , Khan Waqar A. , Bilal Sardar Muhammad , Khan Ilyas
Published: January 2021

This research is mainly concerned with the characteristics of magnetohydrodynamics and Darcy–Forchheimer medium in nanofluid flow between two horizontal plates. A uniformly induced magnetic impact is involved at the direction normal to the lower plate. Darcy–Forchheimer medium is considered between the plates that allow the flow along horizontal axis with additional effects of porosity and friction. The features of Brownian diffusive motion and thermophoresis are disclosed. Governing problems are transformed into nonlinear ordinary problems using appropriate transformations. Numerical Runge–Kutta procedure is applied using MATLAB to solve the problems and acquire the data for velocity field, thermal distribution, and concentration distribution. Results have been plotted graphically. The outcomes indicate that higher viscosity results in decline in fluid flow. Thermal profile receives a decline for larger viscosity parameter; however, Brownian diffusion and thermophoresis appeared as enhancing factors for the said profile. Numerical data indicate that heat flux reduces for viscosity parameter. However, enhancement is observed in skin-friction for elevated values of porosity factor. Data of this paper are practically helpful in industrial and engineering applications of nanofluids.
Performance comparison of axial-flux switched reluctance machines with non-oriented and grain-oriented electrical steel rotors
Authors: Aydoun Racha , Parent Guillaume , Tounzi Abdelmounaïm , Lecointe Jean-Philippe
Published: January 2021

This paper studies the performance of an axial-flux switched reluctance machine (AFSRM) using GOES (grain-oriented electrical steel) in its rotor and comparing it to a NOES (non-oriented electrical steel) rotor. Indeed, the AFSRM structure lends itself well to the use of GOES, especially at the rotor. In order to evaluate the intrinsic capabilities of the AFSRM, self-inductance versus rotor position and static torque were numerically simulated at a given operating point and used as indicators for the NOES and GOES performance comparison. The static torque is also used to determine and compare the torque per volume ratios and grasp the impact of GOES use in a 3D rotating structure. The introduction of GOES in a rotating machine leads to an improvement of the electromagnetic torque mean and maximum values, allowing to evaluate the GOES impact on the machine performance.

The aim of the research was to compare the impact of nano- and micro-sized-zinc on the kinetics of changes in the level of 3-methyladenine, 7-methylguanine, 7-methylguanosine, O-methylguanosine, 1-methyladenosine, N6-methyl-2’-deoxyguanosine in urine of rats with breast cancer. Female Sprague-Dawley rats divided into 3 groups were used in the study. Animals were fed only a control diet or diets supplemented with the nano and micro-sized zinc particles. To induce the mammary cancer (adenocarcinoma), rats were treated with 7,12-dimethylbenz[a]anthracene (DMBA). Modified nucleosides were determined by a validated high performance liquid chromatography coupled to mass spectrometry method. In the first stage of investigations a synergistic activity of nanosized Zn with DMBA on the growth of the neoplastic process was found. During that time a statistically significant increase in the levels of all six examined markers in the rats’ urine was observed. However, as the experiment continued, the supplementation with nanosized zinc caused inhibition of tumour growth, being followed by regression and remission of tumours, as well as, a statistically significant systematic reduction of the levels of methyl derivatives in the urine. Biopsy images indicated grade 1 tumours with multiple inflammatory infiltrates in the group treated with zinc nanoparticles, whereas, in the other groups, moderately-differentiated grade 2 adenocarcinoma was identified. It was found that the biological activity of zinc depends on the size of applied particles, as the treatment with zinc microparticles has not had much effect on cancer progression.
Tercera parte. Pedagogía ambiental y prácticas sostenibles. Capítulo 11. Condiciones para la difusión de los sistemas fotovoltaicos residenciales en Colombia
Authors: Carlos Fernando Morales Sánchez
Published: January 2021

Según el Grupo intergubernamental de expertos sobre el cambio climático (IPCC, por sus siglas en inglés), las fuentes de energía convencionales tales como el petróleo y el carbón, generan emisiones en el planeta causantes del efecto invernadero, así como emisiones de otros gases que producen riesgos para la salud humana (IPCC, 2014). Adicionalmente, la escasez de estos recursos, la elevada incertidumbre en los procesos de prospección y su elevada concentración geográfica, se han traducido en elevados costos, baja confiabilidad en la oferta y tensiones geopolíticas. Como respuesta a esta problemática, ha venido creciendo el uso de energías alternativas tales como la energía solar fotovoltaica, la energía eólica y la biomasa, entre otras. La Agencia Internacional de Energía (IEA) referencia varios beneficios sociales tales como: reducción en el precio de la energía eléctrica derivado de un aumento en la oferta y confiabilidad del servicio (fenómeno conocido como meritorder effect), contribución a la seguridad energética de los países, generación de empleos locales para la instalación y mantenimiento de sistemas descentralizados, fortalecimiento de la seguridad energética y reducción de la contaminación (IEA, 2014). A pesar de la existencia de estos beneficios, el proceso de tránsito hacia las fuentes alternativas es complejo porque los costos de generación usualmente han sido más elevados que los de las fuentes convencionales. De hecho, aun cuando esta diferencia en costos se ha venido reduciendo, persiste una dificultad de fondo: el reto de cambiar todo el paradigma tecnológico asociado los combustibles fósiles como fuente de energía motriz para automóviles, barcos y aviones y fuente de energía eléctrica para diversos usos (Pérez, 2004).

Authors: Büyüksarı Ümit , Akkılıç Hüseyin
Published: January 2021

Surface characteristics were studied for particleboards produced from hydro-thermally treated (HTT) and non-treated (NT) wheat stalk (WS). Wood and wheat stalk particles were used as experimental materials. The wheat stalk particles were subjected to HTT at a temperature of 180 °C for 8 minutes in a steam explosion machine. HTT and NT WS particles were added at 10%, 20%, 30%, and 40% to the wood particles. The surface roughness and wettability of the produced panels were determined. The roughness measurements, average roughness (Ra), maximum roughness (Rmax), and mean peak-to-valley height (Rz) were performed using a ﬁne stylus tracing technique. The wetting behavior of the panels was characterized by the contact angle method (goniometer technique). The contact angle (CA) measurements were obtained by using a KSV Cam-101 Scientiﬁc Instrument connected with a digital camera and computer system. Statistical analyses showed signiﬁcant differences in the surface roughness and wettability of the particleboards following hydro-thermal modiﬁcation. The addition of WS to the panels significantly decreased the roughness values. However, all of the HTT groups exhibited higher roughness compared to NT groups. The CA values decreased when the WS content increased. The wettability of the particleboard containing HTT WS particles was improved.
Verschiedene sprichwörtliche Redensarten – the First Croatian Phraseological Dictionary
Authors: Kovačević Barbara , Štebih Golub Barbara
Published: January 2021

The first Croatian phraseological dictionary, compiled in German under the title Verschiedene sprichwörtliche Redensarten was published as a part of the conversational manual accompanying the last published grammar of the Kajkavian literary language, Grammatik der kroatischen Mundart. Its author, Ignac Kristijanović, had accomplished this pioneering undertaking against the contemporary practice, listing the idioms as separate phraseological units in form of a small phraseological dictionary, and not within the dictionary entries of the general dictionary. The paper deals with the macro- and microstructure of Kristijanović’s dictionary within the theoretical framework of the so-called Zagreb School of Phraseology (Menac, Fink-Arsovski).On the macrostructural level, the analysis focuses on the selection principles of the included units and their order in the dictionary. Special attention is paid to the question which material is included, ie. whether the dictionary contains only idioms defined in accordance with today’s phraseological theory and whether the author makes a distinction between idioms and other fixed multi-word expressions (collocations, proverbs).On the microstructural level, it is being examined which form of a idiom is taken as a lemma and how the Kajkavian idioms are translated on the German side of the dictionary (an equivalent German idiom; a German idiom and the explanation of its meaning; the description of the situation in which the idiom is being used). In addition, the question of dealing with synonymous idioms is discussed.In spite of a sporadically non-systematic treatment of structurally similar idioms as dictionary units, and taking into consideration that the Verschiedene sprichwörtliche Redensarten was compiled in the first half of the 19th century, Kristijanović’s dictionary can be viewed as an interesting and valuable contribution to Croatian and Slavic phraseology and phraseography.

Authors: Minh Thong Nguyen
Published: January 2021

In order to maximize the peroxyl radical trapping capacity of diphenynlamines, the substituents such as N, NMe2, and CF3 are suggested to add to their phenolic rings. The reasonable combination of these substituents at right position can reduce the bond strength of the N-H bond, but still keep the derivatives stable in air.

FREE VIBRATION OF BFGSW BEAMS PARTIALLY RESTING ON PASTERNAK FOUNDATION BASED ON A SINUSOIDAL THEORY
Authors: Le Ich Cong
Published: January 2021

In this paper, free vibration of a bidirectional functionally graded sandwich (BFGSW) beams partially resting on a Pasternak foundation is studied. The beams with three layers, an axially functionally graded core and two bidirectional functionally graded face sheets, are made from a mixture of metal and ceramic. The material properties of the face sheets are considered to vary continuously in both the thickness and length directions by the power-law distributions, and they are estimated by Mori-Tanaka scheme. A sinusoidal shear deformation theory, in which the transverse displacement is split into bending and shear parts, is employed to derive energy expressions of the beam. A finite element formulation is formulated and employed to compute vibration characteristics. Numerical result reveals that the ratio of foundation support to the beam length plays an important role on the vibration behaviour, and the dependence of the frequencies upon the material grading indexes is governed by this ratio. Numerical investigation is carried out to highlight the effects of the material distribution, the layer thickness ratio, the foundation stiffness on the vibration characteristics of the beams. The influence of the aspect ratio on the frequencies of the beams and is also examined and discussed.

Authors: Nguyen Viet-Anh
Published: January 2021

Performance indicators of water supply company can provide important information of its service quality and business efficiency, and be intelligent basis for decision making process. The authors have analyzed key performance indicators of 19 selected municipal water supply systems in Vietnam, including operation and design capacities, treated water quality, unit investment cost, water tariff, non-revenue water (NRW) ratio, and energy consumption rate. The average NRW of the 19 systems was 12.6% which was lower than country-wide value of 21%. The energy consumption rate of selected systems was ranging from 0.16 to 0.5KWh/m3, in average 0.3KWh/m3, which was also lower than country average of 0.35KWh/m3, whereas the rate of energy consumption in municipal water systems in China, USA, Australia, Chile, Canada was ranging from 0.1 to 1.33KWh/m3, depending on ground elevation, transfer distance, influent water quality, and applied technologies for water treatment and transportation. The selected water systems have applied improved treatment technologies such as mechanized coagulation-flocculation, lamella settling tank, dual media sand filter, combined contact clarifier with lamella plates, etc. The average treated water turbidity was ≤0.5NTU. The domestic water tariff of the selected systems was within the country range, from USD0.2 to 0.4/m3. Further, the authors have indicated correlation between selected performance indicators, such as energy consumption rate and non-revenue water ratio. The analytical results shown performance indicators of top water companies in Vietnam were in fairly good position compared to others, but improvements were still needed. Reduction of NRW ratio and keeping it at a low value are other challenges requiring water utility efforts.

MATERIAL FLOW ANALYSIS FOR PRODUCTION LINE AND WASTEWATER TREATMENT IN BREWERY INDUSTRY, AND RECOMMENDATIONS FOR CLEANER PRODUCTION SOLUTIONS
Authors: Huyen Tran Thanh
Published: January 2021

The novelty of this study is to apply Material Flow Analyses (MFAs) for both production line and wastewater treatment processes in a modern-technology beer company with an aim to assess cleaner production opportunities and potentials of the company through different scenarios for each cleaner production measure. As aspect of production line, two energy saving measures were proposed: (1) to reuse water-for-cooling for bottle and keg washing, and  (2) to reuse thermal heat produced during rapid cooling to supply heat for the malt pasting process. The 2nd measure could save 11% of heat needed for malt pasting and 5.5% of steam from boiler that heats keg washing water was reduced in the 1nd solution compared to the case of no heat reuse in loop. Within the wastewater treatment plant (WWTP), the study proposed using biogas to generate energy through CHP (combine heat and power) system, of which electrical power is utilized for the WWTP operation and heat is used to maintain the temperature of sludge anaerobic digester (SAD) through a heat exchanger (HE). The results showed that the energy generated from biogas could compensate 16% of the total energy consumption of the WWTP with 43% (corresponding to 1,735 kWh) of electrical energy saving; 11% of heat saving to maintain SAD system
Characteristics of plasma electrolytic oxidation coatings on 6061 al alloy prepared at different current densities
Authors: Tran Quang-Phu , Dao Van-Da , Pham Van-Hoi
Published: January 2021

Plasma electrolytic oxidation (PEO) has earned much attention due to its powerful and easy formation of hard and corrosion-resistant oxide layers on valve metals, such as Al alloys. Here we report the effects of current density (CD) on microstructure and properties of coatings on 6061 Al alloy by PEO using direct current mode. The electrolyte contains the chemicals of Na2SiO3, Na2WO4´2H2O, and NaH2PO2´H2O. The CDs adopted 5.0, 7.5, 10.0, and 12.5 A/dm2, respectively, for a fixed PEO time of 30 min. The thickness, surface morphology, phase composition, hardness, and corrosion resistance of PEO coatings as the function of the applied CD have been studied and discussed. Studied results show the coating thickness is proportional to the applied CD. When the applied CD increases 2.5 times from 5.0 to 12.5 A/dm2, the growth rate of oxide layers increased by more than 3.5 times, from 0.423 to 1.493 μm/min, respectively. SEM images are characterized by a reduction in the ratio of agglomerate-bumps-region/flatten-region as applied CD increases. However, cracks and larger pores appear when the applied CD is higher than 10.0 A/dm2. X-ray diffraction pattern shows that the main phases of Al, g-Al2O3, α-Al2O3, and W are contained in all coatings. PEO coated sample has the highest hardness of 1290 HV and highest polarization resistance of 8.80 ´ 106 Wcm2 obtained at applied CD 10 A/dm2 which shows the best performance of the coating. The variation in coating performance is explained by microstructure details, specifically phases, compositions of oxide-layers, and micro-pores and cracks.

RESUMO O artigo aborda o processo de desenvolvimento da colaboração profissional em um estudo de aula que envolveu seis professoras de escolas públicas da rede estadual de ensino do Rio Grande do Sul, pertencentes à 15ª Coordenadoria Regional de Educação (15ª CRE), no planejamento de uma aula, a aula de investigação, sobre o tópico curricular ‘metro’ como unidade de medida. A análise qualitativa e interpretativa baseou-se em gravações de áudio das sessões de planejamento da aula, notas de campo, dados constituídos mediante questionários e entrevistas realizadas com as professoras participantes. Os resultados mostram que a colaboração profissional promovida ao longo do estudo de aula foi favorecida pela dinâmica das diferentes etapas do processo e, especialmente, pela relação entre participantes e professores formadores. A colaboração emergiu no contexto de atividades tais como planejamento da aula de investigação, ampliou-se para o ensino em sala de aula, observação e reflexão sobre a aula de investigação, e foi valorizada face ao encorajamento entre as participantes na medida em que as professoras sentiram-se confiantes, encorajadas e acolhidas no grupo.

Authors: Ferreira Jacques de Lima
Published: January 2021

RESUMO Esta investigação apresenta uma pesquisa de abordagem qualitativa do tipo exploratória que foi realizada com 127 alunos da Licenciatura em Pedagogia de uma Universidade particular de Curitiba, que realizam o curso na modalidade presencial, semipresencial e a distância. O objetivo foi a análise e a reflexão sobre a Cultura Digital na Formação de Professores a partir da perspectiva dos discentes. Os dados foram coletados a partir de um questionário online e analisados a partir da perspectiva de Bardin (2011), com o auxílio do software ATLAS.ti. A análise de dados permitiu constatar que os Licenciandos em Pedagogia identificam a Cultura Digital na formação inicial quando a universidade possibilita a presença das tecnologias digitais nos espaços de convivência e o acesso à rede Wi-fi, assim como também reconhecem quando o professor faz uso das tecnologias digitais na prática pedagógica.
EL CONCEPTO DE RESPONSABILIDAD EN LA FILOSOFÍA DE LA PRAXIS DE ADOLFO SÁNCHEZ VÁZQUEZ: UN APORTE A LOS ESTUDIOS ORGANIZACIONALES Y A LA ADMINISTRACIÓN
Authors: Rodríguez Carlos Juan Núñez
Published: January 2021

RESUMEN El objetivo de este trabajo es aportar a la discusión sobre la responsabilidad, pero reconstruyendo la perspectiva del filósofo español-mexicano Adolfo Sánchez Vázquez, pues, por un lado, llama la atención que se plantee la existencia de la responsabilidad social corporativa como algo que existiera de facto, como si fuera una relación de la cual se parte. De hecho, los problemas sociales, ecológicos y económicos a partir de los que se plantea la necesidad de la responsabilidad social corporativa no están resueltos y muchas veces ni siquiera los teóricos lo pueden plantear en las reflexiones que realizan. Por otro lado, hay quienes se atreven a plantear una agenda latinoamericana desde el mundo empresarial y desconociendo la realidad de los pueblos del sur global. Para superar estas dos carencias aquí se reconstruye hermenéuticamente los aspectos centrales que debería considerar toda reflexión sobre la responsabilidad: las contradicciones que produce el capitalismo, las posibles formas de superar dichas contradicciones y los mecanismos que no se pueden dejar de lado en dicha superación. Se discute también el ámbito de la responsabilidad, no es una relación vertical de arriba hacia abajo, sino abajo, de forma horizontal y de ahí con respaldo teórico y la necesidad de la acción para que de abajo vaya hacia arriba, a través de la praxis.
META-ESTUDO CRÍTICO DE PESQUISAS EM ARRANJOS PRODUTIVOS LOCAIS

Published: January 2021

RESUMO Esta pesquisa objetiva analisar a evolução do tema Arranjos Produtivos Locais (APLs) em periódicos brasileiros no período de 1999 a 2018, considerando os principais conhecimentos acumulados. Os APLs constituem uma aglomeração de empresas, desenvolvendo atividades econômicas correlatas e que apresentam vínculos de produção, interação, cooperação e aprendizagem. Com isso, a relevância deste estudo é derivada do conhecimento construído sobre APLs e aponta lacunas que podem induzir novos avanços. A resultante é uma meta-síntese que partiu de uma amostra de 325 artigos empíricos e os submeteu às análises sociométricas, bibliométricas e de conteúdo. Encontrou-se um maior aporte em Institucionalismo, Evolucionismo Econômico e Economia Industrial; com poucos casos de triangulação teórica. Foi possível mapear as variáveis, atributos, fatores, construtos e resultados, bem como as suas interações, intervenientes na dinâmica do objeto. Mas persiste a falta de integração do conhecimento gerado pelas pesquisas, capaz de oferecer um modelo mais completo ao entendimento.
DISCUTINDO A ADEQUAÇÃO DAS ESCALAS DE MENSURAÇÃO DE VALORES AO CONTEXTO DAS INSTITUIÇÕES SEM FINS LUCRATIVOS: UMA ANÁLISE DO INVENTÁRIO DE PERFIS DE VALORES ORGANIZACIONAIS
Authors: Alves Sarah Santos , Carvalho Virgínia Donizete de
Published: January 2021

RESUMO Com o objetivo de examinar as evidências de validade fatorial do Inventário de Perfis de Valores Organizacionais (IPVO) no contexto de instituições sem fins lucrativos, o estudo envolveu uma amostra de 203 respondentes, de 34 organizações. Os resultados da Análise Fatorial Confirmatória e do Escalonamento Multidimensional indicaram que a estrutura fatorial do IPVO foi apenas parcialmente confirmada, com a redução para seis dos oito fatores originais, além de algumas inconsistências na distribuição espacial dos valores. A testagem da nova estrutura para analisar a configuração hierárquica dos valores organizacionais nas instituições estudadas indicou certo grau de coerência dos resultados obtidos com a realidade em foco, a despeito das limitações do instrumento. O conjunto dos resultados conduz a ponderar que o IPVO apresenta um baixo nível de adequação para a análise dos valores organizacionais nesse contexto. As limitações da pesquisa e indicações para estudos futuros são apresentadas, especialmente no que tange à demanda pelo desenvolvimento de novas escalas ou pelo redesenho do IPVO, disponibilizando aos pesquisadores instrumentos nacionais para a mensuração de valores organizacionais que sejam aplicáveis em instituições de diferentes setores de atuação.

RESUMO Abordar a temática dos marcadores sociais da diferença e das interseccionalidades diz respeito a entender suas raízes, consequências e imbricações que produzem e reproduzem desigualdades, resistências e confrontamento das opressões. Neste contexto, as narrativas ficcionais podem constituir formas de representação e produzir insights, pois performam práticas e discursos. Este estudo objetivou analisar os marcadores sociais da diferença e as interseccionalidades representadas na figura do líder organizacional nos filmes Amor sem Escalas, O Diabo veste Prada e Um Senhor Estagiário. No tocante aos procedimentos metodológicos, foi realizada uma pesquisa qualitativa e descritiva, considerando nos filmes, data, sujeitos e lugar. A coleta de dados se deu por meio da microanálise estruturada de cada filme e a discussão ocorreu com base nas categorias de análise dos marcadores sociais da diferença e das interseccionalidades. Conclui-se que as diferenças e interseccionalidades abordadas neste artigo aproximam o contexto organizacional fictício, representado nos filmes examinados, da realidade de muitas organizações, em que se reforçam os padrões normativos através de relações hierárquicas e desiguais. Estas são resultantes do cruzamento dos marcadores sociais da diferença (classe, gênero, raça/etnia, sexualidade e geração), apreendendo um processo de preconceitos interligados, que ocorrem, muitas vezes, de forma sutil e silenciosa na vivência do cotidiano organizacional.

Method: qualitative, exploratory study, based on the Oral History theoretical methodological framework, conducted in a Health Regional of Goiana, Pernambuco, Brazil. Data collection occurred from October 2017 to May 2018, with 13 mothers through individual interviews. The data were processed in a software using the similitude analysis method, which identified the most frequent terms and resulted in the interpretation of the corpus through the words in the light of the reference. Results: the interpretation of the corpus highlights the maternal experiences regarding the discovery of the Congenital Zika Virus Syndrome, of the forced paths implying changes in lifestyle and of the coping strategies used to care for the child. Conclusion: the stories of mothers of children with the syndrome allowed reflection on the challenges related to disability and their children´s need for daily care. The context of the syndrome, associated with low socioeconomic conditions, revealed the magnitude and peculiarities of the problem that permeate the limits to dignity, compromising quality of life and showing the precariousness of the lives of women neglected by the State and society.

ABSTRACT Objective: to analyze the family appraisal about the Down syndrome diagnosis. Method: this is a qualitative, exploratory study, guided by the Resiliency Model of Family Stress, Adjustment, and Adaptation. Semi-structured interviews were conducted with 20 Brazilian parents of children with Down syndrome (19 mothers and 1 father). The data were collected between February and June 2016 and were analyzed using a directed content analysis approach and MAXQDA ©, version 12.2.0 software was used to help manage the data. Results: the moment of suspected or confirmed diagnosis of Down syndrome occurred predominantly in the postnatal period. Parents viewed the experience of being informed of their child’s diagnosis as a negative experience and were mostly dissatisfied with how professionals informed them. Parents reported that, over time, their view of having a child with Down syndrome became more positive. Conclusion: the family's perception of how they were informed of their child’s diagnosis plays a critical role in the family adaptation process and may ultimately contribute to how well they adapt. Findings from this study will help in the identification of key competencies needed by health professionals who engage in informing families about their child's diagnosis of Down syndrome.
