Authors: Perveen Shazia , Naqvi Iftikhar Imam , Masood Summyia
Published: July 2020

In this study, complex formation of benzyl viologen dication (BzV2+) with β-cyclodextrin (β-CD), in
its different oxidation states, had been studied in buffer solution of pH 7, through cyclic voltammetry.
In buffer solution of pH 7, extensive deposition of benzyl viologen neutral (BzVº) has been found.
Further to that first redox process of BzV2+ was found reversible in buffer solution of pH 7. Benzyl
viologen mono-cation (BzV+•) was found to interact with β-CD reversibly according to EC mechanism.
Equilibrium constant of BzV+•-nβ-CD complex in buffer solution of pH 7, has been calculated as 5.49
M-n. The value of n was found to be 0.2. The bimolecular rate constant for the complex formation of
BzV+• with β-CD was found to be 6.44 M-ns− in buffer solution of pH 7. This study is based upon an
electrochemical approach to obtain the bonding equilibrium constant, the rate constants of formation
and the association numbers of the complex formed between reduced forms of viologen and β-CD.
This study explore the electron transfer reaction mechanism of benzyl viologen with β-CD to extend
their applications at neutral pH.

Published: July 2020

The inhibiting action of Thai-bael fruit extract at room temperature on hot-rolled steel in 1M HCl
solution was studied. The chemical functional groups of the green inhibitors were characterized by
Fourier-transformed infrared spectroscopy. The electrochemical activities of steel surface were
investigated through linear polarization measurements, electrochemical impedance spectroscopy,
surface assessment techniques based on optical microscopy and X-ray absorption spectroscopy.
Electrochemical testing samples have been prepared in the form of square plates with the size 1 × 1
cm2. The organic corrosion inhibitor extract from Thai-bael fruit has shown the smallest corrosion
current density (Icorr) of 114.8 μA cm-2 and corrosion potential (Ecorr) of -424.6 mV, compared with
standard Ag/AgCl electrode potential. In comparison, similar tests in the bare HCl solutions yielded
Icorr = 882.4 mA cm-2 and Ecorr = -445.8 mV. The mixed-type corrosion inhibiting behaviour was evidenced
in the results of the polarization measurements. Electrochemical impedance spectroscopy reveals that
the resistance to charge transfer due to the presence of the extracts has been increased by about four
times that of the same test on the bare HCl solution, indicating the formation of a protective layer. The
adsorption of the organic molecules near the steel-electrolyte interface is evident in the decreasing
double-layer capacitance with the enhancing concentration levels of the extract. This latter finding
supports the displacement of the water molecules by means of the adsorption of the inhibitors on the
steel surface. The optical images of steel surface before and after being immersed in HCl solution also
showed pieces of evidence of corrosion retardation. XANES study as well as the linear combination
fitting revealed that the samples immersed in HCl solutions with Thai-bael fruit extract possess less
Fe3+ compositions. All tendencies across the four examinations indicate that Thai-bael fruit extract
could potentially inhibit the corrosion reaction of steel electrodes in the acidic solution.

Published: July 2020

A series of sixteen new ionic liquids (ILs) bearing imidazolium moiety were designed and synthesized under sustainable and green conditions which were confirmed by analytical and spectral techniques using 1H- & 13C-NMR, FT-IR, mass and elemental analysis. A panel of clinically isolated strains was used for in vitro inhibitory antimicrobial activities screening of synthesized ionic liquids. The results of antimicrobial assay showed that some of synthesized ionic liquids showed moderate to good activity. Among these ILs, ionic liquids 3, 4 and 5 (bearing alkyl chain with a phenyl group) significantly inhibited cell growth of strains. In this regard, these ionic liquids considered as promising antibacterial agents when compared with standard antibiotics. By encouraging in vitro antimicrobial screening, in silico ADMET evaluation has been performed and found excellent pharmacokinetic, bioavailability and toxicity profiles. Synthesized ionic liquids has found to be safe and non-toxic according to calculated in vivo computed LD50 values (2.49-2.80 mg/kg) for rat acute toxicity.

In the present investigation, we focused our interest on the synthesis of pharmacophoric units (quinoline and 1,2,3-triazole) linked through ester (3a-b) and (substituted aromatic ring and 1,2,3-triazole) linked through an ether (3c-h). The synthesis involves multiple sequence of reactions viz. diazotization reaction
followed by nucleophilic substitution and finally Cu(I)-catalyzed alkyne azide cycloaddition reaction (CuAAC). The assigned structures of the compound were confirmed by 1H & 13C NMR and mass spectrometry. Prediction of activity spectra for substances (PASS) training set for the synthesized compounds were carried out using PASS software. Interestingly, PASS prediction of the compounds (3a-h) showed that the compounds are more potent as anti-inflammatory (Pa < 0.65) compared to antibacterial (Pa < 0.33) as well as antifungal agents (Pa < 0.35). Furthermore, these compounds were
subjected to in silico ADMETox evaluation. All the compounds were found to pass the ADME evaluation and only few compounds passed the predicted toxicity evaluation. This work could be used as an initial approach in identifying potential novel molecules with promising activity and low toxicity.

Published: July 2020

Growth of a new organic single crystal of N-acetyl-2,6-bis(4-methoxyphenyl)piperidin-4-one
(APM3EPO) is reported by using a slow evaporation method. The characterization of the crystal was
done by IR and NMR spectra. Further, electronic spectrum and TG/DTA studies have also been carried
out. The SHG efficiency of the crystal was found to be closer to that of standard KDP (potassium
dihydrogen orthophosphate) using the modified Kurtz-Perry powder test employing Nd: YAG laser as
the source of IR radiation. The calculated hyperpolarizability values were also projected to confirm
the aptness of the crystal for non-linear optical applications. Optimization of the molecular structure
of APM3EPO is done at the basic level of B3LYP/6-311(d,p) and the corresponding molecular properties
such as HOMO-LOMO and Mulliken charge analyses are carried out at the same level of theory.

La «Vía PRO» como «tercera vía»: un análisis desde la perspectiva de la historia reciente
Authors: Haidar Victoria
Published: July 2020

Entre las consignas y motivos que configuran el discurso de «Propuesta Republicana« (PRO) este artículo procura profundizar la comprensión del concepto de «tercera vía» que sus dirigentes han utilizado para definir su identidad partidaria. Encuadrado en la perspectiva de la  «historia del presente» el trabajo se ocupa de caracterizar y relacionar cuatro de los discursos de tercera vía que, aun con temporalidades y orientaciones político-ideológicas diversas, resuenan en el discurso de PRO. Así, además de presentar y discutir las ideas de la tercera vía post-ideológica emergente en la década de 1990 con la que los dirigentes prefieren identificarlo, el discurso de PRO se pone en diálogo con otras reflexiones acerca de la tercera vía desarrolladas en la II posguerra: así, con el programa de la «economía social de mercado», con el debate que mantuvieron una serie de intelectuales católico-liberales argentinos en torno al proyecto económico-social de la democracia cristiana y con la «tercera posición» peronista.
Debates sobre el estructuralismo y neo-estructuralismo latinoamericano: situando al Estado en un primer plano de análisis
Authors: Ormaechea Emilia , Fernández Víctor Ramiro
Published: July 2020

Partiendo de reconocer el escaso abordaje de las restricciones analíticas asociadas al rol que asume el Estado en la propuesta de desarrollo cepalina, incluso por parte de los enfoques teóricos que se ocuparon de revisar las limitaciones de aquella teoría, el artículo revaloriza las especificidades de los procesos de configuración e implicación estatal para comprender la incapacidad del Estado para direccionar el patrón acumulativo hacia una transformación estructural que incorpore a la industria como motor de desarrollo. En ese sentido, se analiza cómo las prácticas desplegadas sobre y desde los mismos Estados durante el período de la industrialización por sustitución de importaciones terminaron actuando, por un lado, de manera funcional a la recreación de los obstáculos que daban especificidad al patrón de acumulación periférico, y, por otro lado, configurando la propia debilidad del Estado para afrontar las consecuentes transformaciones del capitalismo a escala global suscitadas con posterioridad a 1970.
Relevant Issues of Property Rights Protection in Ukraine
Authors: DOLGOPOLOVA Liubov M. , US Marina V. , GLOTOV Sergiy O.
Published: July 2020

The issue of protecting property rights today is one of the most important, and depends both on the state and in on the owners of these rights. Despite the fact that Ukraine strives to join the European Union, its legal system is still far from international standards. For example, if the owner of property does not possess at least initial knowledge in the field of protecting his rights, then his property may be at risk, problems may emerge not only from authorities, but also from other owners, entrepreneurs or legal entities. Another issue that should be noted is intellectual property, the concept and regulation of which is necessary for the successful development of the state and its investment attractiveness. The main goal of this paper is to analyze the status of the issue of property rights protection in Ukraine and create a development strategy that can be an important component of a national security strategy. In the paper, along with questions of legislative support of citizens` property rights, considered legislative methods of increasing the potential of enterprises and the level of social protection of the population. Based on the experience of protecting property rights in the European Union, it is shown that the basis for legal protection should be economic feasibility, and not the political situation of the executive and legislative branches. As a result, measures were developed with the help of which the legislative framework and human rights activities should be improved to the level of the EU countries, where special attention is paid to human rights, and, therefore, the property.
The Role of International Organizations in Restricting the Use of Humanitarian Intervention for Political Purposes
Authors: OTHMAN Adel Hamzah
Published: July 2020

Humanitarian intervention is often seen as a factor of increasing the level of political presence in one state by another due to its impact on socio-economic processes. Moreover, the presence of the state itself and its government or army is not required. International organizations are used in most cases. The relevance of the study is determined by the fact that humanitarian intervention is now understood as an instrument of soft power, coupled with the use of the international community in the context of cross-cutting information. The novelty of the article is determined by the fact that humanitarian intervention is considered not only as an instrument of political influence, but also as a mechanism for participation in the economic environment of society. The paper shows that under the conditions of the distribution of crisis economic phenomena, humanitarian intervention can only aggravate the situation of the state. It was determined that the most effective tool to increase the political rating of other state is the recovery period after emergency situations. The authors show the mechanism for using the mandatory procedures for the restoration of the country using a political instrument from the most financially secure states. The practical significance of the paper is determined by the need to form a mechanism for differentiating the political impact in the process of restoring the state after an emergency.

Opozycja */u/ : */uː/ w gwarze Jastarni
Authors: Jocz Lechosław
Published: July 2020

The paper is devoted to the reflexes of the old contrast between */u/ and */uː/after labials and velars and in a front position in a word in the Kashubian dialect spoken in Jastarnia. According to descriptions from the late 19th century and the early 20th century, the contrast was preserved at the beginning of a word and in the middle of a word as contrasted with the quantity and quality (with a probable weakening of the first component of the contrast): [u̯ɘ̟] : [u(ː)]. At the end of the word, the contrast was weak and disappeared. According to sources from the mid-20th century, the contrast has been entirely lost in all the positions and [u̯ɘ̟] and [u] are merely free variants of one phoneme /u/. However, an analysis of contemporary material shows clearly that the old contrast was preserved word-initially and word-internally with some cases of simple morphological levelling. Two phonemes, /ʉ/ and /u/, need to be assumed. The current system is strongly correlated with a system documented in the oldest descriptions and could not develop secondarily from a hypothetical system which would merge */u/ and */uː/ to any extent exceeding a free variation in some forms while morphological levelling took place. It seems that the conclusions offered in the publications from the mid-20th century (refuting the existence of the contrast) had an irrational (personal and maybe national) background.
Językowy kształt poradnika gospodarskiego pomieszczonego w „Nowych Wiadomosciach Ekonomicznych i Uczonych" (1758–1761)

The article analyses the structural, pragmatic, cognitive and stylistic aspects of a handbook entitled Introduction to governance, featured in the first Polish popular-scientific journal – “Nowe Wiadomości Ekonomiczne i Uczone” published in Warsaw in 1758–1761 by Wawrzyniec Mitzler de Kolof. It has been demonstrated that the text under analysis, which can be classified as a utility text, shows conspicuous elements of two styles – ordinary (unsophisticated vocabulary; simple syntactic structures; proverbs) and scholarly (pronounced text segmentation, perspective of the author setting himself aside from the recipient; economic terminology; defining new or more difficult concepts; references to foreign (Latin and/or German) counterparts of Polish names of plants).
Dynamic Modulus Characteristics of Mixtures Containing Recycled Asphalt Pavements, Warm Mix Additives, and Antistrip Agents
Authors: Wang Jiayu , Su Ningyi , Xiao Feipeng , Amirkhanian Serji N.
Published: July 2020

The utilization of reclaimed asphalt pavement (RAP) has proven to be a promising technology to solve some of the environmental issues and resource shortages in many parts of the world. The objective of this study was to investigate dynamic modulus and phase angle of surface type mixtures using two warm mix asphalt (WMA) technologies (i.e., warm mix additive E and foaming), and two liquid antistripping agents (ASAs). A total of 20 mixtures were designed and tested. Viscoelastic master curve modeling, statistical analysis, as well as continuous relaxation spectrums were conducted to obtain a better understanding of the properties of the mixtures. The results implied that RAP or WMA technologies had significant effects on mechanical performances, which should be carefully considered during mix design, but ASA agents, statistically, did not have such effects. In addition, the influence of RAP depended on WMA technology type, and the effects of ASA agents relied on aggregate and RAP source. The rheological index showed that both WMA technologies and ASA materials had negative impacts on the rheological properties of the mixtures, but the addition of RAP mitigates this impact only for mixtures containing ASA additives. Furthermore, the continuous relaxation spectrum confirmed the negative influences of WMA technologies and no obvious effects of ASA materials.
The Effects of Nonproportional Biaxial Loading Paths on Ductile Fracture Initiation: A Void Growth Analysis
Authors: Jin Zhaoyu , Wang Xin , Liu Zheng , Chen Xu
Published: July 2020

The effects of nonproportional biaxial loading paths on ductile fracture initiation toughness are studied in this article. To this end, the growth of a cylindrical void (hole) located in front of a mode I plane strain crack has been studied using large-deformation finite element analysis. A specific microstructural feature of a steel alloy was thoroughly studied by having a single void positioned at a fixed distance from the crack tip and void that was equal to 10 times the diameter of the void. In particular, the nonproportional biaxial loading path effects on the crack tip blunting, void growth, ligament reduction, and near-tip stress fields are investigated computationally. Under small-scale yielding conditions, one proportional loading and two nonproportional loading paths are applied to the modified boundary layer models, covering both low-constraint (negative T-stress) and high-constraint (positive T-stress) crack tip conditions. We have observed that the nonproportional load paths have a marked effect on the void growth, crack tip blunting, and the resulting ligament reduction. By applying the simple criteria for the coalescence of the crack tip and void, the ductile fracture initiation toughness is estimated. It is shown that the ductile fracture toughness is dependent on loading paths and constraint conditions (the T-stress ratios). Compared with the proportional biaxial loading case, different load sequences of the biaxial loads will result in either an increase or a decrease the fracture initiation toughness. This effect is particularly significant for specimen geometry with low-constraint conditions (i.e., negative T-stress ratios). Results from this study are of relevance to ductile fracture assessment of components or structures, such as pressure vessels that operate under nonproportional biaxial loading conditions.

Introduction: Metastatic tumors are the most frequent tumors of the heart with the melanoma metastasis being the most frequent. In cases of a cardiac tamponade or a low cardiac output syndrome due to the position of the tumor it could lead to an acute life-threatening condition for the patient.
Case report: We present a case of a successfully treated metastatic cardiac melanoma in a lifesaving cardiac surgery. A 42-year-old woman was admitted to the emergency department of the Clinical Center of Serbia in a critical state with signs of tricuspid orifice obstruction with a tumor mass. Her previous medical history showed that she had an adequate surgical excision of the melanoma in the right lumbar region at the age of 39. An emergency cardiac surgery was performed with the resection of the tumor and the atrial wall. The postoperative course was uneventful and a HP exam once again confirmed the same type of melanoma as previously diagnosed. The patient was alive and well on follow-up exams for 4 months when she was diagnosed with metastatic tumor masses in the pelvis with ascites and melanosis of the entire skin followed by lethal outcome 5 months after the cardiac surgery.
Conclusion: Surgical resection of metastatic cardiac melanoma can be safe and effective in an emergency scenario, especially in the case of solitary metastasis. It can be performed with excellent results and very few postoperative complications. However, due to the nature of the principal disease, the long-term survival rate remains low, giving the surgery a place in palliative treatment.

El municipio de Tumaco, ubicado al sur de Colombia, en el departamento de Nariño, ha atravesado momentos de cambio en los últimos 20 años. La situación de pobreza, el boom en el negocio de la coca, la violencia y la globalización han sido factores importantes para que la población afrodescendiente, ubicada en esta parte del país, cambie y deje atrás sus dinámicas identitarias y tradiciones. Sin embargo, ante esta realidad existen iniciativas de resistencia que la comunidad ha implementado para rescatar lo propio. Este artículo examina na iniciativa que se lleva a cabo en el barrio Nuevo Milenio y es el Centro Cultural Afro, el cual, a través de la identidad, la memoria y el arte popular, empodera a los niños y jóvenes de esta comunidad para salir adelante y así dejar de lado el camino de la violencia. Asimismo, se expone cómo se ven estos jóvenes y cómo entienden su entorno.
Entre la emancipación y la captura: autonomización de la palabra y resistencia a las necropolíticas en los territorios indígenas nasa (Colombia)
Authors: Ferrari Simone
Published: July 2020

En el proceso de construcción de la categoría de ciudadano en Colombia han primado prácticas constitutivas excluyentes, fundadas en una división sistemática entre individuos considerados dignos de ser ciudadanos e homines sacri (Agamben), es decir, hombres marginados y sacrificables. Dichas prácticas han contribuido a la formación de espacios de tolerancia de dinámicas de dominación necropolítica (Mbembe). El nororiente del Cauca es un caso de territorio en donde se ha sido permitido un ejercicio constante de necropolíticas, manifestadas tanto en el actuar de los centros de poder como en sus construcciones discursivas. Sin embargo, en una región históricamente capaz de generar epicentros de resistencias, ¿las comunidades locales se piensan en tanto marginadas?, ¿cuáles imaginarios de disidencia se están produciendo en el territorio? La propuesta del presente artículo se orientó a la indagación de las respuestas más actuales que se están elaborando en la comunidad nasa del Cauca. El proceso investigativo se centró en el análisis de la configuración y del uso de nuevas prácticas discursivas en el texto Entre la emancipación y la captura (2017) de la escritora Vilma Almendra, quien, a través de un trabajo de textura de voces comunitarias, se propuso replicar a las marginalizaciones impuestas por medio de un replantamiento descolonizador de la función de la palabra, con el fin de proteger el “territorio del imaginario” de las intervenciones estatales.
The Importance of MMR Immunization in the United States
Authors: Perrone Olivia , Meissner H. Cody
Published: July 2020

Despite the established safety and efficacy of the measles-mumps-rubella vaccine after almost 50 years of widespread use, the United States is encountering higher levels of measles and mumps disease than has occurred for years. Return of disease threatens the health of those who remain unimmunized by choice as well as those who are immunized appropriately but experience loss of vaccine-induced immunity. The solution to continued threats of illness caused by these untreatable but readily preventable diseases is compliance with recommendations for administration of the measles-mumps-rubella vaccine. Here we examine trends in the epidemiology of measles, mumps, and rubella in recent years and consider the consequences of loss of protective immunity within our country.

Published: July 2020

Objetivos: verificar o número e as causas de hospitalizações por quedas em idosos brasileiros, além dos gastos federais do Sistema Único de Saúde (SUS), no período de 2000 a 2018.Métodos: trata-se de um estudo ecológico, utilizando informações disponíveis na base de dados do Departamento de Informática do SUS. Foram coletados dados de idosos (≥60 anos) que internaram no SUS devido às quedas no período de 2000 a 2018 no Brasil. Extraíram-se o número de hospitalizações no País e nas regiões (Norte, Nordeste, Sul, Sudeste e Centro-Oeste), as causas das quedas (Classificação Estatística Internacional de Doenças e Problemas Relacionados à Saúde – 10) e o valor de gastos federais. Para fins estatísticos, utilizou-se análise descritiva.Resultados: totalizaram-se 1,48 milhões de hospitalizações por quedas em idosos no Brasil, com uma taxa de 38,6 a cada 10 mil. As principais causas desses registros no DATASUS foram as “quedas sem especificações”, as “outras quedas no mesmo nível” e as “quedas no mesmo nível por escorregão, tropeção ou passos em falsos”. Em relação às localidades, os idosos pertencentes às regiões Sudeste (47,1), Sul (44,1) e Centro-Oeste (40,4) foram aqueles que apresentaram maiores medianas das taxas de hospitalizações por quedas no período analisado. Entretanto, o Nordeste (variação%=0,4), o Sul (variação%=0,2) e o Centro-Oeste (variação%=0,2) demonstraram maiores elevações desse indicador ao longo dos 18 anos, enquanto apenas a região Norte apresentou redução (variação%=-0,5). A mediana de gastos hospitalares federais (milhões) foi de R$135,58, variando de R$112,89 até R$194,98.Conclusões: houve aumento das taxas de hospitalizações por quedas em idosos no SUS em quase todas as unidades federativas. As causas mais frequentes foram as “quedas sem especificações”, as “outras quedas no mesmo nível” e as “quedas no mesmo nível por escorregão, tropeção ou passos em falsos”. Além disso, ocorreu elevação dos gastos hospitalares federais ao longo do período no País.
Universais existem? Uma análise a partir da Teoria da Percepção de Searle
Authors: Castro Neto José Carlos Camillo
Published: July 2020

Este artigo tem como objetivo revisitar a questão da existência dos universais. Essa questão foi muito debatida na Filosofia Medieval pelos nominalistas e realistas, especialmente influenciados pela leitura de Aristóteles. A questão também levantou debate na filosofia analítica e foi discutida por Strawson e Quine, além de lembrada por Searle. Neste trabalho, será investigado se os universais existem e em que qualidade de existência se encaixam tendo como principal pano de fundo a teoria da percepção de John Searle. Contudo, para isso, o assunto será analisado em seu contexto na filosofia contemporânea. Por isso, será exposta a definição strawsoniana de universais. Depois, será discutida a proposta do comprometimento ontológico de Quine e as críticas que recebeu de Searle. Construído esse cenário, será apresentada a teoria da percepção de Searle e, então, serão discutidas as consequências de tal teoria para um estudo ontológico dos universais. Conclui-se neste trabalho que a teoria da percepção consegue explicar bem a formação de conteúdo Intencional através do objeto e que, portanto, o universal como parte do objeto, tendo características no mundo físico, deve existir como entidade não linguística.

Diálogos sobre o bullying escolar e o desenvolvimento humano
Authors: Monteiro Michelle Popenga Geraim , Asinelii-Luz Araci
Published: July 2020

Este trabalho destaca o bullying escolar e suas implicações no desenvolvimento humano.  O artigo originou-se de uma pesquisa de mestrado em educação que investigou a percepção do bullying junto a duas turmas de quinto ano do Ensino Fundamental, envolvendo 38 estudantes com idades entre 9 e 11 anos, meninos e meninas. A análise dos dados deste presente estudo é de natureza qualitativa. Para a coleta de dados utilizou-se um questionário semiestruturado com 26 questões. Mostraram-se relevantes ao estudo questões relacionadas ao fenômeno e suas implicações no desenvolvimento humano, podendo afirmar que a escola, da forma como estabelece as relações interpessoais, pode ser entendida como um microssistema onde a violência também se manifesta como bullying, como sintoma da violência social na escola. Acredita-se que o microssistema escola é necessário ao desenvolvimento humano, acolhendo e respeitando os estudantes vitimizados, encorajando a Cultura de Paz e não-violência.
A efervescência do modo de pensar de Gilles Deleuze: conexões e proposições no cenário educacional
Authors: Silva Lilian dos Santos
Published: July 2020

No campo da educação, comumente iluminado pelo prisma da recognição e da representação, acionar o modo de pensamento de Gilles Deleuze e convocá-lo como companhia de pesquisa é soltar um comprimido efervescente em um copo d'água. O líquido muda, as moléculas se agitam; há movimento, barulho, ruído, excitação, entusiasmo, tumulto, transformação. Isso porque no contexto de ensino regido pela matriz platônica, as ideias do filósofo são uma perturbação. Uma euforia. Suas proposições desafiam o pensamento, tirando a segurança de processos, sem salvaguardar nada, e rompendo limites estabelecidos e consagrados. Nesse cenário, o objetivo deste artigo é apresentar alguns pontos de ebulição do modo de pensar de Gilles Deleuze, por meio de proposições do próprio filósofo. A partir delas, armam-se conexões com outros autores e com a literatura. Trata-se de Antonio Candido e Marcel Proust. Dessa forma, intenciona-se ensaiar possibilidades com a educação e, ao mesmo tempo, jogar luz na radicalidade que há na filosofia deleuziana.
Uma análise das permanências e rupturas em duas políticas de ampliação da jornada escolar brasileiras: CIACs e PME
Authors: Diniz Junior Carlos Antonio
Published: July 2020

Este trabalho tem como objetivo analisar as permanências e rupturas existentes em duas políticas de ampliação da jornada escolar no Brasil, implementadas no período de 1991 a 2015, quais sejam os Centros Integrados de Apoio à Criança (CIACs) e o Programa Mais Educação (PME).  Tendo por referência metodológica a análise documental dos textos editados por estas políticas, pode-se destacar que, tanto os CIACs como o PME se constituíram sob a égide da atuação de diversos atores sociais em suas ações bem como da focalização do público atendido – população em situação de vulnerabilidade social -  sob a perspectiva da proteção social. Aponta-se também que, diferentemente do que ocorreu no PME, os CIACs previam investimento de recursos para a construção de espaços físicos para a sua implementação. O espaço físico a ser utilizado também se altera nas duas políticas, sendo que a primeira (CIACs) tem a centralidade na escola e, no caso do PME, a utilização de outros é incentivada para a garantia das ações. Destaca-se ainda a influencia dos textos editados por organismos internacionais para a elaboração e modus operandi das duas políticas.
Puerto Rico: El colapso de un país. Una reflexión inicial sobre el debacle de la industria azucarera, las petroquímicas y la sección 936.
Authors: Aleman Iglesias Javier
Published: July 2020

En el siguiente trabajo tenemos como objetivo central examinar las implicaciones socio-económicas de la desintegración de la economía de Puerto Rico a partir de la segunda mitad del siglo XX, usando como centro de estudio los casos de la industria azucarera, la industria de la petroquímicas-CORCO y las industrias bajo el sector de la sección 936. Los tres sectores fueron en su momento de apogeo las actividades más importantes en la economía puertorriqueña durante del siglo XX; no obstante, los tres sectores fueron desplazados y arruinados por situaciones locales e internacionales, causando una de las crisis económicas más grandes de nuestra historia contemporánea.
ASSESSMENT OF FLASH-FLOOD SUSCEPTIBILITY IN SMALL RIVER BASINS
Authors: Dragomir Andreea , Tudorache Andreea-Violeta , Costache Romulus
Published: July 2020

Due to the climate changes occurred in the last decades the frequency and intensity of hydrological risk phenomena are also increasing. The flash-floods are considered the most devastating natural hazards around worldwide. The identification of areas with a high flash-flood potential and also of the valleys with a high potential for flash-flood propagation is mandatory to be included in the flash-flood risk management activity. In this regard the present study proposes a GIS methodology to identify the flash-flood potential along river valleys from small catchments. The analysis carried out into a number of 5 small river basins across Romania revealed that a high percentage of river network is characterized by a high and very high flash-flood potential. The results of the present study can be successfully used in the flash-flood risk management activity and also in the activity of flash-flood forecast and warning.
The mediation role of work-life balance stress and chronic fatigue in the relationship between workaholism and depression among Chinese male workers in Hong Kong
Authors: Yang Xue , Qiu Dan , Lau Mason C. M. , Lau Joseph T. F.
Published: July 2020

Background and aims

Few studies have tested the underlying mechanisms in the association between workaholism and depression. This study aims to investigate the potential mediation effects of work-life balance stress and chronic fatigue and depression among Chinese male workers in Hong Kong.

Methods

A population-based study among male workers in Hong Kong (n =  1,352) was conducted. The self-reported scales of assessing workaholism, work-life balance stress, chronic fatigue and depressive symptoms were included in the questionnaire. Path analysis was conducted to test the proposed mediation model.

Results

Workaholism was directly and indirectly associated with depression through work-life balance stress and chronic fatigue, respectively. The association between work-life balance stress and chronic fatigue was statistically significant in the correlation analysis but not in the path analysis. As high as 30.5% of the participants were classified as having probable chronic fatigue, while 8.4% of the participants were classified as having probable depression.

Discussion

Workaholism is a stressor that may induce negative consequences on well-being and health among male workers in Hong Kong. Interventions to help workers with time and stress management and fatigue reduction may be beneficial for their mental health. Theoretical and practical implications are discussed.
The development of the Compulsive Sexual Behavior Disorder Scale (CSBD-19): An ICD-11 based screening measure across three languages
Authors: Bőthe Beáta , Potenza Marc N. , Griffiths Mark D. , Kraus Shane W. , Klein Verena , Fuss Johannes , Demetrovics Zsolt
Published: July 2020

Background

Compulsive Sexual Behavior Disorder (CSBD) is included in the eleventh edition of The International Classification of Diseases (ICD-11) as an impulse-control disorder.

Aims

The aim of the present work was to develop a scale (Compulsive Sexual Behavior Disorder Scale–CSBD-19) that can reliably and validly assess CSBD based on ICD-11 diagnostic guidelines.

Method

Four independent samples of 9,325 individuals completed self-reported measures from three countries (the United States, Hungary, and Germany). The psychometric properties of the CSBD-19 were examined in terms of factor structure, reliability, measurement invariance, and theoretically relevant correlates. A potential threshold was determined to identify individuals with an elevated risk of CSBD.

Results

The five-factor model of the CSBD-19 (i.e., control, salience, relapse, dissatisfaction, and negative consequences) had an excellent fit to the data and demonstrated appropriate associations with the correlates. Measurement invariance suggested that the CSBD-19 functions similarly across languages. Men had higher means than women. A score of 50 points was found as an optimal threshold to identify individuals at high-risk of CSBD.

Conclusions

The CSBD-19 is a short, valid, and reliable measure of potential CSBD based on ICD-11 diagnostic guidelines. Its use in large-scale, cross-cultural studies may promote the identification and understanding of individuals with a high risk of CSBD.

Background

Gambling and gaming disorders have been included as “disorders due to addictive behaviors” in the International Classification of Diseases (ICD-11). Other problematic behaviors may be considered as “other specified disorders due to addictive behaviors (6C5Y).”

Methods

Narrative review, experts' opinions.

Results

We suggest the following meta-level criteria for considering potential addictive behaviors as fulfilling the category of “other specified disorders due to addictive behaviors”:

1. Clinical relevance: Empirical evidence from multiple scientific studies demonstrates that the specific potential addictive behavior is clinically relevant and individuals experience negative consequences and functional impairments in daily life due to the problematic and potentially addictive behavior.

2. Theoretical embedding: Current theories and theoretical models belonging to the field of research on addictive behaviors describe and explain most appropriately the candidate phenomenon of a potential addictive behavior.

3. Empirical evidence: Data based on self-reports, clinical interviews, surveys, behavioral experiments, and, if available, biological investigations (neural, physiological, genetic) suggest that psychological (and neurobiological) mechanisms involved in other addictive behaviors are also valid for the candidate phenomenon. Varying degrees of support for problematic forms of pornography use, buying and shopping, and use of social networks are available. These conditions may fit the category of “other specified disorders due to addictive behaviors”.

Conclusion

It is important not to over-pathologize everyday-life behavior while concurrently not trivializing conditions that are of clinical importance and that deserve public health considerations. The proposed meta-level-criteria may help guide both research efforts and clinical practice.
