Published: April 2020

Background:

Spinal cord stimulation is an efficient treatment for selected patients with chronic neuropathic pain. Since 2015, neuromodulation nurses at Kuopio University Hospital have been responsible for patient education and stimulator adjustments.

Aims:

The purpose is to determine what factors professionals perceived to affect patients' wellbeing in the neuromodulation process for chronic neuropathic pain.

Methods:

Four nurses and four physicians on the neuromodulation team performed a strengths, weaknesses, opportunities and threats analysis of the operational environment. All evaluated the attributes independently, and a multiple-criteria analysis was performed based on the results.

Findings:

The most important factors were excellent or good treatment results, having neuromodulation nurses, having a well-functioning neuromodulation team, vulnerability because of the limited number of specialists, and the establishment of a pain centre.

Conclusion:

This study highlights the importance of neuromodulation nurses and teamwork in chronic pain neuromodulation. The establishment of a multidisciplinary pain centre is strongly recommended.
Microbiological analysis of water and thickeners used for people with dysphagia
Authors: Boaden Elizabeth , Thomas Lois , Higham Susan , Watkins Caroline
Published: April 2020

Background:

Thickened fluids are a recognised intervention strategy in use for people with dysphagia. However, their bacterial profile has not previously been examined.

Aims:

To identify bacteria and changes in bacterial profiles in a range of water sources and thickener preparations over a 5-day period.

Methods:

Nine experiments were performed using a range of preparations of water (sterile, drinking, non-drinking tap water) and a thickening agent (sterile sachet and a used tin).

Findings:

No bacteria were grown on serial subcultures of sterile water, both with and without thickener. Drinking, tap and thickened water left at room temperature for 24 hours may become contaminated with environmental organisms.

Conclusions:

The growth of bacteria in preparations of thickening agent appears to be dependent upon water quality, while the proliferation of bacteria is dependent upon the length of time the preparation is allowed to stand at room temperature.
Investigation on temperature controlling multifunctional selector in superconducting photonic crystals based on Thue–Morse sequence
Authors: Hu Caixing , Guo Sijia , Zhang Haifeng , Ma Yu
Published: April 2020

In this paper, a novel one-dimensional superconducting photonic crystal exploiting the Thue–Morse arrangement is theoretically investigated by the transfer matrix method. Two transmission states are switched in utilization of ambient temperature in the case of the same structure in the terahertz regime: one is the omnidirectional photonic bandgap (OBG) characteristics in low-temperature zones (about 10 K), and the other is wide-angle broadband absorption characteristics in high-temperature zones (about 90 K). Due to the modulation of temperature-dependent superconducting complex permittivity, the proposed structure can induce the OBG and broadband absorption at different temperatures. From the numerical results, the OBG can be notably tuned by manipulating the structural parameter of high refractive index dielectric. The effects of superconducting thickness on the switchable function regions are also considered. The proposed structure can possess both environment stable zero-

OBG at 10 K and preeminent broadband absorption in the TM polarization at 90 K, which offers theoretical guidance to the design of temperature switchable function selectors.
Nonlinear dynamics in a dipolariton cavity with a squeezed vacuum
Authors: Jabri H. , Eleuch H.
Published: April 2020

Dipolaritons are quasiparticles formed in double quantum wells’
microcavities driven by a coherent field. Here, we investigate the
correlations and the quantum fluctuations in the light emitted by a
dipolariton cavity pumped by a laser. By studying the noise spectrum
in the strong and weak coupling regimes, we show that the squeezing
generated by the direct and indirect excitonic nonlinearities is
strongly enhanced by coupling the system to a squeezed vacuum. As a
consequence, this coupling transforms the statistical light propriety
from coherent to highly squeezed states, depending on the squeeze
parameter strength. Furthermore, the squeezed reservoir stabilizes the
nonclassical effect even with the high fluctuations caused by indirect
exciton nonlinearity. It turns out that the combination of excitonic
nonlinearities and squeezed vacuum is a good solution for producing
stable and strong squeezing.
Comparing the fundamental imaging depth limit of two-photon, three-photon, and non-degenerate two-photon microscopy
Authors: Cheng Xiaojun , Sadegh Sanaz , Zilpelwar Sharvari , Devor Anna , Tian Lei , Boas David A.
Published: April 2020

We have systematically characterized the degradation of imaging quality with depth in deep brain multi-photon microscopy, utilizing our recently developed numerical model that computes wave propagation in scattering media. The signal-to-background ratio (SBR) and the resolution determined by the width of the point spread function are obtained as functions of depth. We compare the imaging quality of two-photon (2PM), three-photon (3PM), and non-degenerate two-photon microscopy (ND-2PM) for mouse brain imaging. We show that the imaging depth of 2PM and ND-2PM are fundamentally limited by the SBR, while the SBR remains approximately invariant with imaging depth for 3PM. Instead, the imaging depth of 3PM is limited by the degradation of the resolution, if there is sufficient laser power to maintain the signal level at large depth. The roles of the concentration of dye molecules, the numerical aperture of the input light, the anisotropy factor

g

, noise level, input laser power, and the effect of temporal broadening are also discussed.

Menos insegurança hoje, mais liberdade amanhã. O passado ensina
Authors: Alves Sérgio , Valente Isabel Maria Freitas
Published: April 2020

Este ensaio está divido em duas partes intimamente interligadas. A primeira delas – “A burocracia da destruição” – refere-se ao mais contundente episódio de aniquilação sistemática do “inimigo”, a partir da negação dos seus direitos e da subestimação de seus atributos humanos. Na outra parte – “Homo homini lupus” – procura-se mostrar que a índole das pessoas e a trajetória histórica dos povos podem convergir em uma resultante que possibilita acontecer aquilo que os homens normais não imaginam que aconteça, cujo exemplo maior – embora não único – é o holocausto, o qual foi promovido pelo movimento totalitário nacional-socialista e sistematizado por um grupo burocrático-ideológico fanatizado. A breve consideração final, à guisa de conclusão, diz respeito à crença no aprendizado da geração atual com as que lhes antecederam no conturbado século XX. A maior estabilidade sociopolítica, nomeadamente na Europa de hoje, contribui para uma melhor convivência entre pessoas, maior confiança entre países e mais liberdade para todos.

Representations of Learning Disabilities in Portugal
Authors: Albuquerque Cristina Petrucci
Published: April 2020

It is essential to study learning disabilities (LD) representations by education professionals since they are the ones who are more directly involved in their identification and intervention. This research analyzes the representations of the concept of LD of 310 Portuguese education professionals (regular education teachers, special education teachers, and psychologists). Through a questionnaire that consists of three parts, we examine the perspectives of the professionals regarding: 1) the identification criteria (e.g., exclusion; discrepancy; RTI) and the phenomenology of LD (manifestations; specific nature of LD); 2) the use, broad or narrow, of the LD term; and 3) the Portuguese legislation regarding LD. The results obtained indicate the agreement with the manifestations of LD (e.g., low achievement), with the criterion of discrepancy and with a dimensional view of LD. The professionals considered that LD may be due to contextual factors (e.g., socioeconomic disadvantage, family interactions, and inadequate teaching conditions). Participants also expressed agreement with a very comprehensive use of the term (e.g., in the absence of a diagnosis, in school failure situations). Education professionals also expressed a negative perspective regarding the educational support given to LD in Portugal. The comparisons between professional groups have documented the existence of certain significant differences.
Addressing Exploitation in Supply Chains: Is technology a game changer for worker voice?
Authors: Berg Laurie , Farbenblum Bassina , Kintominas Angela
Published: April 2020

Multinational businesses are facing mounting pressure to identify and address risks of exploitation, trafficking and modern slavery in their supply chains. Digital worker reporting tools present unprecedented opportunities for lead firms to reach out directly to hard-to-reach workers for feedback on their working conditions via their mobile phone. These new technologies promise an efficient and cost-effective way to cut through the complexity of global production, gathering unmediated data on working conditions directly from workers at scale. As the market for these tools grows, this paper contextualises their emergence within the broader political economy of supply chain governance. It presents three sets of concerns about their use that must be addressed by businesses, investors, donors and governments that develop or utilise these tools. First, the quality of data gathered by these tools may be inadequate to reliably inform decision-making. Second, global brands may gather large quantities of worker data to identify legal, reputational and financial risks without addressing structural causes of exploitation or delivering outcomes for workers. Third, large scale collection of data from workers creates new risks for workers’ wellbeing and safety.
Lavar as mãos contra o Coronavírus: mas, e a Água?
Authors: Nascimento Denise Morado
Published: April 2020

Nesse momento da expansão da COVID-19, o  Ministério da Saúde, em consonância com a Organização Mundial da Saúde, vem fortemente recomendando uma principal medida para reduzir o contágio pelo coronavírus: lavar as mãos. Entretanto, lavar as mãos não é possibilidade para 35 milhões de brasileiros que não tem acesso à água,

Diante desse cenário, espera-se que políticas públicas emergenciais em territórios assim caracterizados sejam conduzidas por governos municipais e estaduais, apoiados por organizações não-governamentais e entidades voluntárias. Parece ser natural, para não dizer óbvio, que se medidas estratégicas relativas ao acesso à água e ao saneamento são tomadas, a capacidade de organização dos serviços nas redes públicas de saúde melhora, sendo urgente efetivar as recomendações feitas pelo Observatório Nacional dos Direitos à Água e ao Saneamento (ONDAS).
Periodización y taxonomía de la lexicografía diferencial paraguaya
Authors: Peralta de Aguayo Estela Mary
Published: April 2020

En el presente artículo, se estudian diferentes obras que recogen el léxico distintivo del español hablado en el Paraguay con el objetivo de establecer una periodización y taxonomía inicial de la lexicografía diferencial paraguaya. Se toma como corpus nueve obras. Mediante el análisis metalexicográfico se esboza una línea histórica, que data de 1968 hasta el año 2016, siguiendo el modelo propuesto por Matus (1994), así como la clasificación de la tipología de las obras producidas. Con los resultados obtenidos se perfilan dos vertientes de las producciones: las que tienen como fin ser complementarias del Diccionario de la Real Academia Española, en que se asignan las obras de carácter semasiológico y fraseológico, y la otra según el ceñimiento a la teoría lexicográfica, de la cual se desprenden dos tipologías: la científica, en la que se agrupan las producciones que siguen en cierta medida la teoría lexicográfica y las acientíficas, que reúnen las obras que colectan voces de matiz diferencial, pero teñidas por el humor. Se destaca que las obras en cuestión son productos individuales y que a partir del siglo XXI se percibe una evolución en la confección de los diccionarios.

Authors: Tekkurşun Demir Gönül , Cicioğlu Halil İbrahim , İlhan Ekrem Levent
Published: April 2020

Quantitative research model was used in the study, which aimed to develop a valid and reliable measurement tool to measure the level of anxiety of catching novel coronavirus (Covid-19). A total of 356 athletes participated in the study consisting of two study groups. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to determine the construct validity of the scale. As a result of the EFA, it was seen that ACNCS explained 57.80 of the total variance, the scale items were collected in two factors as individual anxiety and socialization anxiety and that the scale was composed of 16 items. The conformity of the structure determined with EFA to the sample data was tested with CFA and it was determined that the fit indices resulting from EFA confirm the two-factor structure obtained in EFA. In line with the internal consistency analysis and test-retest analysis conducted to test the reliability of ACNCS, it was determined that the scale has a highly reliable and time-stable structure. Within the scope of item analysis, 27% lower-upper group score differences were found to be significant and the total test correlation values of the item varied between .56 and .78. As a result of all these analyses, Anxiety of Catching Novel Coronavirus (Covid-19) Scale was found to be a valid and reliable measurement tool. ​Extended English summary is in the end of Full Text PDF (TURKISH) file.

Authors: Nirmalasari Novita , Mardiyono Mardiyono , Dharmana Edi , Arifin Thohar
Published: April 2020

Background: Dyspnea and physiological changes are clinical manifestations of Congestive Heart Failure (CHF) due to respiratory failure. Deep breathing exercise combined with active range of motion increases respiratory muscles and blood circulation. As a result, it reduces breathing effort and decreases blood pressure.Purpose: This research aimed to analyze the influence of deep breathing exercise and active range of motion (ROM) on physiological response of CHF patients.Methods: This study used a quasi-experiment with pretest-posttest control group design recruiting 32 respondents by stratified random sampling technique. The intervention was done three times a day for three days. Deep breathing exercise for thirty times and continued with active range of motion for five times each movement was given. Digital sphygmomanometer and digital watch were used as measuring instruments. Data were analyzed using independent and paired t-tests.Result: The results showed that there were significant differences in the systole (p=0.000), diastole (p=0.000) and respiratory rates (p=0.003) after the intervention compared to the control group. There was also a significant difference in systolic blood pressure between the intervention and the control group (p=0.003). However, no significant difference in diastole and respiratory rates was found.Conclusion: Deep breathing exercise combined with active range of motion decreases the systole in CHF patients. Further research is expected to lengthen the time of intervention to allow better significance.

Data were collected using the z scores and questionnaires for children aged 12-59 months, food trust questionnaire, feeding practice questionnaire and child eating habits questionnaire. The Chi Square test and multivariable logistic regression were performed for the data analysis.Results: Children who were not exclusively breastfed and had major infectious disease had a higher risk of stunting for 53.8% and 40.9%, respectively. There was a significant relationship between the history of exclusive breastfeeding (p=0.001, OR=2.28), the history of infection (p=0.013, OR= 2.27), and eating habits (p=0.04, OR=1.55) with stunting in children.Conclusion: There is a relationship between the history of exclusive breastfeeding, the history of infection and eating habits of children with stunting. The formation of a peer group community of children aged 12-59 months is expected to prevent and overcome stunting and improve nutritional status and optimal development of the children.
Wędrująca idea awangardy. Centrum Dekontaminacji Kulturowej i serbska kultura oporu
Authors: Bogusławska Magdalena
Published: April 2020

The article addresses the presence of the avant-garde in the discourse and the practice of social resistance in Serbia at the turn of the 20th and 21st centuries. The focal point of the text is the thesis that nowadays the avant-garde resonates not so much as an artistic formation, but as an ideological complex. The author investigates the manners of contemporary transposition of ideas and avant- garde imagination through the analysis of the activities of the Centre for Cultural Decontamination in Belgrade. Using the examples of two programmes: Modernism, Serbian National Identity in 20th Century and En Garde – Avant-Garde 20/21, the author shows how the local experience of the interwar avant-garde and the neo-avant-garde formed within the movement of ʼ68 protests, creates a specific ideological current, a model of self-organization and a pattern of activities bordering between art and socio-political reality. In the 1990s, in Serbia, it becomes the reference system for artivism (an approach consisting in influencing social and political reality through art), and today still remains an inspiration for independent intellectual and artistic environments and for critical institutions that create an alternative and polemic cultural space to the official policies of the Serbian authorities.
The Slav Avant-garde in Australian Art
Authors: Bojić Zoja
Published: April 2020

Australian art history includes a peculiar short period during which the European avant-garde values were brought to Australia by a group of Slav artists who gathered in Adelaide in 1950. They were brothers Voitre (1919–1999) and Dušan Marek (1926–1993) from Bohemia, Władysław (1918–1999) and Ludwik Dutkiewicz (1921–2008) from Poland, and Stanislaus (Stanislav, Stan) Rapotec (1911–1997) from Yugoslavia, later joined by Joseph Stanislaus Ostoja-Kotkowski (1922–1994) from Poland. Each of these artists went on to leave their individual mark on the overall Australian art practice. This brief moment of the artists’ working and exhibiting together also enriched their later individual work with the very idea of a common Slav cultural memory.

AVALIAÇÃO DA CONCENTRAÇÃO DE SÓLIDOS TOTAIS NA BACIA DO RIO PARAOPEBA APÓS RUPTURA DA BARRAGEM I – BRUMADINHO
Authors: De Andrade Stella Braga , Do Vale Vítor Lages , Maia Saliba Aloysio Portugal , Nascimento Nilo De Oliveira
Published: April 2020

A ruptura da Barragem I da Mina Córrego do Feijão ocorreu no dia 25/01/2019 e trouxe ao rio Paraopeba grande quantidade de rejeitos que alteraram significativamente a concentração de sólidos totais deste curso d`água. Imediatamente após o colapso dessa estrutura o IGAM, CPRM, COPASA e VALE iniciaram monitoramentos diários de diversos parâmetros de qualidade de água, dentre eles a concentração de sólidos totais (CST). Contudo, a bacia do rio Paraopeba, devido ao seu uso e ocupação, é uma bacia com diversas fontes de sólidos, de forma que se observa na análise dos dados significativas variações da CST entre as estações de monitoramento.  Para melhor avaliação da CST analisou-se 60 km do rio Paraopeba, divididos em 6 trechos, no período entre 30/01/2019 a 31/03/2019. Para fins de interpretação da interferência da ruptura da Barragem I na CST da bacia, os dados dos pontos de monitoramento considerados neste estudo foram comparados aos dados da série histórica do primeiro trimestre dos últimos 10 anos, tanto das estações de monitoramento do IGAM ao longo do rio Paraopeba, quanto com as estações localizadas nos principais afluentes. Essa comparação demonstrou que, a 50 km da confluência, a mediana da série é similar a mediana da série histórica da estação posicionada a 1,7 km a jusante. Observou-se ainda que neste ponto os atuais valores máximos observados entre final de fevereiro e final de março de 2019 são inferiores aos valores da série histórica observados para o principal afluente do trecho, o rio Betim.
ANÁLISE DO COMPORTAMENTO DA VAZÃO E PRECIPITAÇÃO NA INFLUÊNCIA DE ENCHENTES NA BACIA HIDROGRÁFICA A MONTANTE DA CIDADE DE ITAJUBÁ

Published: April 2020

As enchentes são eventos hidrológicos que causam sérios danos ambientais, econômicos e sociais. Com o aumento da precipitação na estação chuvosa e à maior frequência de chuvas intensas, a vazão dos cursos hídricos tende a aumentar. Tal fato, associado à urbanização sem planejamento e ao crescimento desordenado de cidades ao longo dos cursos d’água, vem favorecendo a ocorrência de tais eventos. A cidade de Itajubá, que se encontra inserida na bacia hidrográfica do rio Sapucaí, já presenciou vários eventos de enchentes. A bacia apresenta características morfométricas propícias a enchentes, o que faz com que a área demande uma atenção especial. Diante disso, o objetivo deste trabalho foi de analisar o comportamento das vazões e precipitação desta bacia hidrográfica ao longo do tempo e verificar tendências de aumento ou redução nessas variáveis hidrometeorológicas. Foram aplicados testes não paramétricos de Mann-Kendall e Pettitt para a análise de tendências e conhecimento do ponto de mudança do comportamento da série. Foram analisados dados de vazões máximas, médias e mínimas ao longo do tempo e para cada mês e a precipitação máxima diária, a precipitação total anual e total mensal. Duas estações pluviométricas e fluviométricas foram analisadas, a montante e a jusante na área. De alguns resultados obtidos, na estação fluviométrica a montante, as vazões máximas mensais em geral apresentaram redução e as vazões mínimas mensais aumentaram na estação fluviométrica a montante. Na estação fluviométrica mais a jusante, a vazão máxima mensal em dezembro reduziu. Ambas as estações pluviométricas apresentaram defasagem do início do ano hidrológico. As chuvas máximas das estações não se intensificaram e a bacia apresentou condições adequadas de conservação tratando-se de vazões.

O presente artigo aborda o estudo da extração dos contaminantes químicos da classe dos cresóis, presente no lodo de esgoto, a fim de viabilizar seu uso no meio agrícola, evitando a contaminação do solo e dos mananciais hídricos. A agricultura é um setor vital, intrínseco ao abastecimento alimentício, no entanto, é também um potencial poluidor. Dessa forma, alternativas sustentáveis têm sido desenvolvidas para a destinação e uso apropriado do lodo de esgoto no setor. Composto por diversos contaminantes químicos, como os cresóis, o lodo, quando disposto ao solo, pode apresentar riscos diretos à água, ocasionado pela lixiviação de compostos e escoamento superficial, fazendo-se necessário o monitoramento contínuo, a fim de assegurar a qualidade e conservação dos recursos hídricos. Este trabalho tem como objetivo realizar a extração dos cresóis em amostras reais de solo, através de um procedimento rápido, fácil, barato, efetivo, robusto e seguro (QuEChERS) por meio da cromatografia gasosa acoplada ao espectrômetro de massas, CG-EM. Com base no estudo, a taxa de extração dos compostos foi não satisfatória. Todavia, os agentes derivatizantes proporcionaram estabilidade às reações. De modo geral, o estudo se mostra essencial para a continuidade de pesquisas que viabilizem a aplicabilidade do lodo de esgoto, sem que este culmine na vulnerabilidade e contaminação da água, afetando sua qualidade e uso.

Faculty Development and Dissemination of Knowledge on Active Learning by Higher Education Leaders
Authors: Tozini Kelber , Hubacz Haylea
Published: April 2020

With faculty development programs being more present around higher education institutions worldwide, researchers question their effectiveness as how it benefits faculty members and students. For development programs to take place, effective dissemination processes must become a common practice, and be strongly encouraged by the leadership. This paper presents a case study on how dissemination of knowledge works after leaders of several Brazilian institutions that are part of a consortium attend a weeklong workshop on active learning methodologies. This study employed a mixed methods approach utilizing the review of program documentation, an online leader survey, and virtual interviews with select participants. This multi-phase study revealed several ways leaders disseminate knowledge within and outside their institutions - including internal and external communities of practice - and that in most cases the high administration is willing to invest on creating an environment which fosters the dissemination. However, some challenges still compromise the complete effectiveness of the dissemination, including the involvement of the leadership of the consortium post-program. This paper sheds light on the role of leaders in this process in addition to presenting a case study in Latin America, context that is still understudied.
As contribuições da tese de William Paton (1922) — Accounting Theory
Authors: Da Silva Figueiredo Vanuza
Published: April 2020

Este trabalho tem o objetivo de identificar as principais contribuições sobre o fator de impacto da tese de William Andrew Paton (1922). Uma tese desenvolvida há quase um século, mas que permanece atual e relevante fonte de dados para o entendimento da teoria da Contabilidade ao longo dos anos. Mesmo de forma embrionária, esta obra traz uma contribuição para a ideia de mensuração e uma introdução ao conceito de “custo corrente”. Trata-se de uma pesquisa exploratória, que utilizou o método empregado por Oppenheim e Renn (1978) para a análise de tipologias de citações, por meio do qual pudemos observar que a maioria das citações foi classificada na tipologia c. Os resultados também evidenciaram, por um lado, que as principais contribuições da obra de Paton (1922) consistem no custo corrente, no goodwill e nos postulados.

Published: April 2020

Aim: to study orthostatic hemodynamic changes in patients with chronic disorders of consciousness after critical brain damage.

Materials and methods. We studied 30 patients (10 women and 20 men) with chronic disorders of consciousness after severe brain damage aged 45±7 years, 10 of which were in the vegetative state (VS) and 20 had the minimally conscious state (MCS). The main causes of brain damage were traumatic brain injury (53% of patients) and cerebrovascular accidents (CVA) (23.3%). The rest of the patients had posthypoxic encephalopathy or were after brain tumor removal surgery. Passive orthostatic test (POT) 0° to 60° to 0° was performed using an electrically driven tilt table (Vario Line). Hemodynamic monitoring during the verticalization was done using a non-invasive oscillometric recording of blood pressure on the brachial artery, stroke volume (SV) and cardiac minute output (CMO) were measured by impedance cardiography with the multifunctional «Task Force Monitor 3010i» (CNSystem, Austria). Data were statistically analyzed using the Statistica 10 software package.

Results. Orthostatic hemodynamic stability was found in 26 out of 30 patients with chronic disorders of consciousness after critical brain damage. It was manifested by stable systolic blood pressure (SBP) in tilted orthostatic and horizontal position (120.7±2.2 and 121.1±3.6 mmHg, respectively, P>0.05). Orthostatic hypotension was observed in 3 patients and postural tachycardia syndrome (PTS) in one patient. We compared orthostatic hemodynamic changes in the studied cohort versus published data on orthostatic hemodynamic changes uncluding POT revealed in patients with severe brain damage examined before and after brain death.

Conclusion. Orthostatic stability of blood circulation can be maintained for a short period of time in patients surviving after critical diffuse brain damage associated with chronic disorders of consciousness. Critical brain damage resulting in brain death associates with a significant reduction of all hemodynamic parameters and severe orthostatic hypotension with restoration of initial blood pressure values when the patient is returned to the horizontal position.

Professional activity of intensivists consistently ranks high among the most «risky» areas of medicine. In 6 out of 89 criminal «iatrogenic» cases initiated by investigative authorities in the Moscow region in 2016–2018 anesthesiological or intensive care in the ICU was the subject of investigation. In 4 of these 6 cases, iatrogenic complications were detected during the forensic examination. Intensivist is considered an attending doctor and therefore holds responsibility for defects in the provision of medical care and its adverse outcome.

The purpose of the study is to outline the professional risks in the work of an intensivist and identify ways to reduce them by using a case study with a fatal outcome, which led to criminal proceedings.

Materials and methods. We studied and analyzed the criminal case files which included the complaint of the patient’s relatives with the prosecutor’s office, the explanations and interrogation records of the patient’s relatives (4) and healthcare workers (6), the minutes of the Morbidity and Mortality conference, the expert report on patient care quality issued by health insurance company, the final report of sanitary and epidemiological examination, autopsy protocol, emergency call files (3), the inpatient medical records, outpatient records and the final report of Commission of forensic medical examination.

Results. Defects in the provision of medical care were not identified. The differential diagnosis was performed correctly. The severity of the patient's condition was due to brain infarction and associated abnormalities. Underdiagnosis of botulism did not affect the outcome of the disease and was not the cause of death of the patient.

Conclusion. The reasons for filing a complaint with the Prosecutor's office and initiating a criminal case were organizational shortcomings and ethical and deontological aspects.

Badly Equipped, Under-financed, Technologically Backward but Splendidly Uniformed: A Brief View into Austria- Hungary’s Efforts in the Eastern Front and the Battle of Galicia
Authors: Sweeney Jack
Published: April 2020

The purpose of this study was to research the role that Austria-Hungary played in the Eastern Front of the First World War. Specifically, there is research into their clumsy actions in the tragic battle of Galicia. The research was conducted through the works of several historians that focus on Austria-Hungary and Russia in the First World War. Overall, the weak leadership, trans cultural makeup of the army, and the sheer numbers of the imperial Russian Army resulted in a complete rout in both the Battle of Galicia and the Brusilov Offensive. If it had not been for the sheer power and efficiency of Germany, the Austro-Hungary Empire would have capitulated to Russia in the first year of the war.
Gender and Memory: Depictions of Femininity in Irish Revolutionary Art
Authors: Joslyn Pearl
Published: April 2020

This paper uses artistic depictions of the allegorical figure, Kathleen ni Houlihan, who represented the personification of Ireland, to analyze the role of gender in the Irish Revolution. Drawing on a number of primary source artistic works from the years surrounding the 1916 Easter Rising, this paper questions the impact highly gendered portrayals of Irish nationalism had on nationalist communities. This paper also relies on primary and secondary sources that highlight the highly gendered environment of revolutionary Ireland, and the hardships faced by nationalist women. In this study, I found that gendered depictions of Kathleen ni Houlihan were rooted in the gendered revolutionary environment, and reflected typical ideas of the roles men and women should play in the independence movement. The figure of Kathleen ni Houlihan offers an excellent case study of the role the arts played in both reflecting and altering Irish revolutionary society. Additionally, these artistic portrayals reflect the strict binaries of Irish society at the turn of the century, and provide insight into the ways women negotiated their positions in the revolution.
The Gender Correctional Machine: Institutional Mechanisms that Reinforce a Patriarchal Gender Order in Correctional Facilities
Authors: Robalino Micaela
Published: April 2020

Mass incarceration is a feminist struggle. Not only are women the fastest growing population in correctional facilities in the United States but they also face institutional regulations that aim at "correcting" their gender and sexual "deviance." Correction, within women's correctional facilities, refers to the structural attempt to enforce a gendered, class-based, and racialized order. The mechanism that allows the gender correctional machine to be enacted functions through two branches: correctional industries and library content. This study examines the extent to which regulatory programs, such as limited labor options and libraries, are actually constructed through male-gaze-dominated norms. By looking at the connection between vocational programs and the prison-industrial complex, it is evident that labor-oriented programs not only exploit women but do so in a gendered way. Low-waged, traditionally feminine, and potentially racialized training within the facilities showcase the regulatory mechanism to keep women "were they belong." Furthermore, this study imports the theoretical lens of Laura Mulvey's notion of the male gaze into the area of sociology of law, and seeks to understand how prison libraries enforce patriarchal norms. By looking at denied and permitted library publications in the Philadelphia Department of Prisons, this study shows that the male gaze functions as a normalizing and correcting force in the ways that gender and sexuality are visually portrayed in publications' covers. Thus, the study unveils the regulatory mechanisms of the gender correctional machine, and proposes radical resistance as an alternative to it.

The inclusion of a compressor in absorption refrigeration systems is one of the practices that are becoming more common in the refrigeration field, since a lower generation temperature is required. Among the mixtures most used and studied in refrigeration-compression cycles (CARC) are NH3-LiNO3 and NH3-NaSCN. This is mainly due to the assumption that these two mixtures have a better energy efficiency than the conventional absorption refrigeration cycle working with NH3-H2O (BARC). Therefore, this work shows an energy and exergy study of a CARC cycle, in which its analysis extends to the use of the NH3-H2O mixture, to show the potential that presents the mixture for refrigeration and air conditions applications, as well as the advantages and disadvantages to operating in this type of configurations. The results obtained are compared with the mixtures NH3-LiNO3 and NH3-NaSCN at different evaporation, condensation, generation temperatures and different compressor pressure ratio. The results show that the generation temperature, as well as the energetic and exergetic efficiency are strongly dependent on the compressor pressure ratio. For compression ratio values lesser than 1.6, NH3-NaSCN mixture is energetically higher than NH3-H2O and NH3-LiNO3 at generation temperatures higher than 70°C. The results show the three mixtures have very similar exergetic behavior for almost all wide range of operating conditions. When the system works with rp=2.0, the COP of NH3-H2O mixture is 3.26% higher than the other two mixtures, while under the same operations conditions, the energetic behavior is very similar for the three mixtures for different generation and evaporation temperatures.

OBJECTIVES:

To determine if in utero selective serotonin reuptake inhibitor (SSRI) or selective serotonin norepinephrine inhibitor (SNRI) exposure is associated with developmental vulnerability in kindergarten among children whose mothers were diagnosed with prenatal mood or anxiety disorder.

METHODS:

Linkable administrative data were used to create a population-based cohort of 266 479 mother-child dyads of children born in Manitoba, Canada, between 1996 and 2014, with follow-up through 2015. The sample was restricted to mothers who had a mood or anxiety disorder diagnosis between 90 days before conception (N = 13 818). Exposed women had ≥2 SSRI or SNRI dispensations during pregnancy (n = 2055); unexposed mothers did not have a dispensation of an SSRI or SNRI during pregnancy (n = 10 017). The Early Development Instrument (EDI) was used to assess developmental health in kindergarten children. The EDI is a 104-component kindergarten teacher-administered questionnaire, encompassing 5 developmental domains.

RESULTS:

Of the 3048 children included in the study who met inclusion criteria and had an EDI, 21.43% of children in the exposed group were assessed as vulnerable on 2 or more domains versus 16.16% of children in the unexposed group (adjusted odds ratio = 1.43; 95% confidence interval 1.08–1.90). Children in the exposed group also had a significant risk of being vulnerable in language and/or cognition (adjusted odds ratio = 1.40; 95% confidence interval 1.03–1.90).

CONCLUSIONS:

Exposure to SSRIs or SNRIs during pregnancy was associated with an increased risk of developmental vulnerability and an increased risk of deficits in language and/or cognition. Replication of results is necessary before clinical implications can be reached.
Evidence of effective financial crisis management from South Korea: An example for other regions
Authors: Sayaseng Saysi
Published: April 2020

Evidence from the global financial crisis (2007–2008) and the Asian financial crisis (1997) have taught policymakers valuable lessons. The contagious effects of these crises have proven unavoidable and have led to negative economic development. However, South Korea, unlike other countries, has recovered remarkably from both episodes of financial turmoil and proved their ability to maintain positive growth throughout the two periods. This study investigates the correlation between the evolution of South Korean banking and corporate sector before, during and after these crises. A VAR model was employed to test the effectiveness of the South Korean government's policies, in response to the financial crisis from 1997 to 2017, using macroeconomic variables as proxies for newly introduced policies, and non-performing loans for controlled risks. The empirical results indicate impulse response functions which suggest that changes in macroeconomic variables as a representation for the policies resulted in a reduction of non-performing loans. This implies successful risk reduction and an overall economic recovery.
