La A/R/Tografía como perspectiva metodológica inicial en programas de mediación artística basados en Arteterapia
Authors: González-García Ricardo
Published: October 2020

El presente artículo parte de la perspectiva A/R/Tográfica como método de indagación cualitativa que puede llevar al artista-investigador-docente a plantearse los ámbitos de mediación artística, que incluyan programas de intervención basados en Arteterapia, como espacios donde poder colaborar. Sin alentar ninguna intrusión profesional, y respetando en todo momento los cometidos destinados a cada agente, se contempla la relación entre la A/R/Tografía y la Arteterapia, dentro del contexto de la mediación artística, como una posible conversación interdisciplinar. Un diálogo que puede ayudar a la intervención arteterapéutica a tener en cuenta las virtudes suscritas a la A/R/Tografía, y su actitud investigadora, al imbricarse procesualmente en el desarrollo de este tipo de programas partiendo del importante rol que ahí cumple la pedagogía. Por eso que, desde una visión antropológica, se haga aquí necesario distinguir los objetivos propios de cada agente, y de la propia mediación artística como posible entorno unificador de ambos campos. En el sentido de discernir las parcelas del conocimiento que cada agente puede abarcar, se muestra un diagrama que informa de la amplia confluencia disciplinar posible a desplegar en intervenciones ateterapéuticas de contextos mediados artísticamente, las cuales, a su vez, pueden llegar a constituirse como investigaciones cualitativas. Esta compleja revisión que supone el tema planteado, dada la multitud de interrelaciones disciplinares contempladas, finalmente enfatiza el importante papel común que, considerando el arte como vehículo en los programas de intervención-investigación, desempeñan los procesos de simbolización para conseguir los resultados deseados en ambos ámbitos.
La mediación cultural a través de la práctica artística. Cuando no existía la palabra…
Authors: López-Aparicio Pérez Isidro , Mejías Vanesa Cejudo
Published: October 2020

La Mediación Cultural como proceso de construcción dentro del territorio artístico se hace patente ante la necesidad de articular ciertas prácticas que no se circunscriben ni en lo propiamente artístico (entendiéndolo dentro de las lógicas clásicas de la hermenéutica artística); ni en el campo de la cooperación, dado su profundo carácter creativo, personal y estético.
Por otro lado, la "Mediación Cultural" como término, comienza a nombrarse en España en un contexto muy particular, una crisis económica, institucional y social que hace necesario nombrar la multitud de acciones o intenciones de hacer cultura desde otro lugar diferente al de la industria cultural. Y una manera de crear dentro del territorio artístico en donde lo estético y lo ético entra en diálogo para poder abrir nuevas líneas de aproximación a situaciones de difícil resolución y comprensión. Un arte y una cultura que opera a través de procesos de mediación entre la realidad y las personas a las que interpela con su acción.
Este proceso es lento y requiere empatizar con la realidad encontrada desde el respeto y la participación del entorno, donde acción y reflexión convergen de una manera naturalizada, teniendo claro, como bien defiende el campo de la antropología, que el mero hecho de estar y observar, altera su condición primaria. La Mediación Cultural por lo tanto, permite ejercer desde lo cotidiano una praxis extraordinaria (el proceso artístico) que genera con su acción-reflexión una consecuencia en un contexto concreto.
Con este artículo se pretende ahondar en ciertas claves de la Mediación Cultural a través de la práctica artística de isidro López-Aparicio (iLA), una forma de hacer en el arte y lo social que hasta ahora se encontraba desprovisto de terminología en el campo disciplinar. El desarrollo de este escrito, por lo tanto, es una aproximación a esta manera de operar en el territorio de lo social a través del arte.

Introducción. Territorio Mediación: un escenario para remover intenciones en la formación de profesorado.
Authors: García Cano Marta , Cebrián Ana
Published: October 2020

Podríamos hablar de la mediación como un escenario para remover intenciones, así lo entendemos las autoras de este monográfico. Pero, como disciplina, la mediación, en el contexto arte y museos (centros de arte, salas…), es el espacio que se destina a la interrelación entre, obra, sala, público y educadoras, con el fin de fomentar el acceso a la cultura y la comprensión de las muestras, las actividades asociadas a ella que habitualmente se inscriben en un programa educativo donde, solo en ocasiones, lleva a cabo una labor real que suponga transitar el camino  para conocer al otro, de lo otro, y llegar a un entendimiento.

Ese proceso, es inevitablemente un generador de conflicto, en la medida que todo aquello que nos es desconocido o extraño genera, cuanto menos, incertidumbre. Su fin se sustenta, no sólo en el acceso al arte, debe implicar también, que la institución arte, entienda a aquellos a quienes pretende dirigirse. Un ejercicio de comprensión mutua que asume diferentes formatos, dependiendo de donde se produzca la mediación y del lugar o personas de donde parten las iniciativas, pero, que, en cualquier caso, trata de dar sentido pedagógico a toda una serie de acontecimientos que nos atañen.

Published: October 2020

Aim of study: To evaluate soil organic carbon (SOC) sequestration and stock over the succession of maize to winter cover crops under a short-term no-tillage system.Area of study: A subtropical area in Southern Brazil.Material and methods: The experiment was implemented in 2013. The treatments were: seven winter cover crops single cultivated (white-oats, black-oats, annual-ryegrass, canola, vetch, fodder-radish and red-clover); an intercropping (black-oats + vetch); and a fallow, with maize in succession. Soil samples were collected after four years of experimentation, up to 0.60 m depth, for SOC determination.Main results: SOC stocks at 0-0.6 m depth ranged from 96.2 to 107.8 t/ha. The SOC stocks (0-0.60 m depth) were higher under vetch and black-oats, with an expressive increase of 23 and 20% for C stocks in the 0.45-0.60 m layer, compared to fallow. Thus, SOC sequestration rates (0-0.60 m depth), with vetch and black oats, were 1.68 and 0.93 t/ha·yr, respectively.Research highlights: The establishment of a high-quality and high C input cover crops in the winter, as vetch or black-oats in succession to maize, are able to increase SOC stocks, even in the short term.
Gender and Civil Engineering in Higher Education: The Case of Mauritius
Authors: Baguant Noshmee Devi
Published: October 2020

Engineering plays a crucial role in everyday life and is the backbone of growth and development of the world including Mauritius. To embrace development, higher education institutions have to ensure that students are equipped with appropriate knowledge and skills to meet the needs of the country. Unfortunately, data shows that there is an underlying gender disparity in civil engineering training in higher education. It is imperative to understand the causes of gender inequity in engineering in higher education. This paper summarises the findings obtained from in-depth critical individual conversations with three participants, which explored the under-representation of undergraduate female students in a civil engineering degree in a higher education institution in Mauritius. The aim was to find ways in which the recruitment of female students in higher education and advancement of women in the field of civil engineering can be achieved. The findings support the ‘non-visibility’ of civil engineering as a field to study by women and the need to fit in as an engineer by women. As a result of the research, recommendations were made to assist policy and decision makers to develop evidence-based policies to address gender inequity in engineering in higher education.
The Degree that Nature of Scientific Knowledge Aspects are Included in the Science Classes of Greek High Schools
Authors: Koumara Anna , Plakitsi Katerina
Published: October 2020

The present study examines the integration level of the Nature of Scientific Knowledge in secondary school science classes in Greece. The research was designed and organized on the basis of the Cultural-Historical Activity Theory. The activity system of the researchers, who use the proper tools each time, are in network relations with the activity system of Science Education. Major components of the educational system are studied (the curriculum, textbooks, teachers’ know-how and teaching methods, school inspectors’ viewpoints, students’ knowledge) in relation to the nature of scientific knowledge, to ensure valid results. The curriculum and textbook content is decoded, the knowledge of teachers and students is assessed with the use of an internationally validated questionnaire, and interview protocols are analyzed. Research results reveal that the nature of scientific knowledge is included in a small degree in the curriculum and textbooks, teachers refer intuitively to some of these aspects, without assessing the knowledge of students, and, finally, the majority of high-school graduate students have naïve views regarding the nature of scientific knowledge.

Extensive cattle ranching had been the most common farming practice in northwestern Paraná State (Brazil), where soils originate from the Caiuá Sandstone. But this reality is changing with the growing cultivation of grain crops, especially soybeans. This study aimed to evaluate different soybean cropping systems in terms of yield components, plant dry matter, and soil chemical properties. The soil is classified as a dystrophic sandy Red Argisol, which derived from the Caiuá Sandstone, in northwestern Paraná State (Brazil). The experiment was carried out in the city of Umuarama (PR), Brazil, under a no-till system for three years. Treatments consisted of the following crop rotation systems: T1: congo grass/soybeans, congo grass/soybeans, congo grass/soybeans; T2: black oats + rye/soybeans, black oats + radish/grain sorghum, black oats + rye/soybeans; T3: triticale/corn, grain sorghum/soybeans, triticale/ soybeans; T4: crambe/grain sorghum, canola/corn, safflower/soybeans; T5: lupine/corn + congo grass, beans/corn, buckwheat/black oats/congo grass. The experiment was arranged in a randomized block design, with four replications and 300-m2 plots. The data were subjected to analysis of variance, and means were compared by the Tukey’s test at 5% significance. The highest grain yield was obtained when soybeans were sown after white oats harvesting. Plant dry matter increased in the system with lupine/corn + congo grass, beans/corn, buckwheat/white oats/soybeans. However, none of the systems had an effect on soil chemical properties during the three crop years.

Published: October 2020

This study aimed to expand knowledge about tick parasitism on wild birds in western Amazonia and provide additional records of species parasitized by ticks in the state of Acre. Birds were captured with mist nets from September 2016 to February 2017 at the Fazenda Experimental Catuaba, in Senador Guiomard, Acre State, Brazil, identified, and thoroughly inspected. Detected ticks were removed with tweezers, stored in labeled collectors containing 70% alcohol, and identified using a stereomicroscope with incident lighting and taxonomic keys at the Department of Preventive Veterinary Medicine and Animal Health of the School of Veterinary Medicine and Animal Science of the University of São Paulo. In total, 203 wild birds were captured, comprising nine orders and 24 families. Among them, 24 birds (11.82%) belonging to 13 species were parasitized by 44 ticks at different stages: 26 Amblyomma sp. larvae, 10 Amblyomma nodosum nymphs, four Amblyomma longirostre nymphs, and four Amblyomma humerale nymphs. This study reports for the first time nine new species of birds as hosts of ticks of the genus Amblyomma in the state of Acre, namely: Monasa nigrifrons, Hypocnemis subflava, Dendrocincla fuliginosa, Sittasomus griseicapillus, Xiphorhynchus guttatoides, Poecilotriccus latirostris, Hemitriccus flammulatus, Ramphotrigon megacephalum, and Turdus amaurochalinus. This study also records, for the first time, A. nodosum ticks parasitizing R. megacephalum and A. humerale parasitizing Momotus momota, S. griseicapillus, and X. guttatoides.

Published: October 2020

This study examined the effectiveness of control measures for caprine arthritis-encephalitis in a herd with 431 dairy goats in an intensive rearing system. All animals older than six months were initially tested by agar gel immunodiffusion (AGID) and separated into seropositive and seronegative. Control measures were implemented for two years and ten months. Five serological examinations were subsequently performed two by AGID and three by the Western Blot (WB) technique. In these tests, animals that tested negative in the previous serological examination were evaluated along with those older than six months which had not yet been examined. The effectiveness of control was evaluated based on the incidence of the disease. Seroconverted animals were stratified according to age, physiological status and dam serology. For the effect of time, logistic regression was performed at the 5% significance level, with values converted into likelihood. General incidence and incidence as a function of age and physiological status were evaluated by analysis of variance, with means compared by Tukey’s test at 5% significance. The ratio test was used for incidence and physiological status, and the agreement between the AGID and WB tests was determined by the Kappa coefficient. Animals that seroconverted and were born to positive dams were compared with those born to dams negative at birth by the Chi-square test, and the same was applied for the number of discarded animals. Initially, 54.24% (179/330) positive and 257 seroconverted animals were identified after the start of control. Higher incidence occurred in the animals aged between 13 and 36 months and in lactating does. Seroconversions among offspring of seropositive dams were higher than in the offspring of seronegative dams (p < 0.001). High infection rates were identified in the sires. The obtained results were not satisfactory, as the measures did not help to prevent new cases, indicating that there are moments of infection yet to be elucidated. On farms that aim to control the disease, the following measures are required in addition to those already recommended: use of diagnostic tests with less frequency; application of high-sensitivity tests in the offspring; immediate separation of kids from dams at birth; separation of kids according to the serological status of the dams; inclusion of kids from unsupervised births in the group of kids from positive dams; and keeping positive and negative animals on different farms or greatly distanced. In herds for which there is an intention to establish control, it is important to determine whether the productive losses associated with the disease are greater than the costs of implementing more efficient measures.

Mastitis is responsible for both damage to animal health and economic losses to the industry. To identify effective treatments for this disease, products extracted from a variety of plants with antimicrobial potential have gained attention. The present study aimed to assess the in vitro antibacterial potential of the ethanolic extract of two plant species from the Caatinga biome against bacteria isolated from small ruminants with subclinical mastitis. The leaves of Mimosa tenuiflora and Commiphora leptophloeos were dried and processed to obtain crude ethanolic extracts and their phenolic composition was evaluated. In total, 33 Staphylococcus spp. isolates from the bacterial collection of the Laboratory of Food Quality Control of IF SERTÃO-PE were used for evaluation of biofilm production. Furthermore, an antimicrobial susceptibility test was conducted using the minimal bactericidal concentration (MBC) method against the two ethanolic extracts. The toxic potential was measured through a toxicity test with Artemia salina. The quantification of the phenolic compounds revealed that the ethanolic extracts of M. tenuiflora and C. leptophloeos possessed higher amounts of myricetin (43.2 and 294.9 mg in 10 g, respectively) in relation to the other compounds. A 39.4% positivity rate was observed in the nuc gene investigation. The biofilm production analysis revealed that 96.9% of the isolates produced biofilm, evidencing the evolution the microorganisms regarding the development of resistance mechanisms. The MBC results showed an inhibition range between 195.30 and 3125.00 µg mL-1 and between 781.20 and 6250.00 µg mL-1 for the extracts of M. tenuiflora and C. leptophloeos, respectively. The M. tenuiflora extract showed the highest activity, suppressing 100% of the bacterial isolates (n=26), whereas the extract of C. leptophloeos showed an inhibition percentage of 69.23%. The crude ethanolic extract (EEB) of M. tenuiflora was found to be toxic, presenting a DL50 of 118.356 µg mL-1. In contrast, the EEB of C. leptophloeos was found to be non-toxic (DL50 = 1527.430 µg mL-1). In conclusion, both native Caatinga species presented antibacterial activity and myricetin was the major compound. These findings highlight the need for further studies regarding the identification of anti-mastitis products from natural extracts.
Bench-Top Comparison of Three Different Types of Stents Used for Treatment of Intracranial Atherosclerotic Stenosis
Authors: Park Jung-soo , Kwak Hyo Sung , Kim Jin-Woo
Published: October 2020

Purpose: Four key bench-top tests, including trackability, conformability, wall-apposition, and bending stiffness, were performed to understand the mechanical characteristics in 3 different types of stents applicable for treatment of intracranial atherosclerotic stenosis: Balloon-expandable D+Storm, Pro-Kinetic Energy, and self-expandable Wingspan stents.Materials and Methods: Trackability was assessed by measuring the tracking forces of each stent with its delivery systems. Conformability and wall apposition were quantified and analyzed using curved vessel models. A 3-point bending test was employed to evaluate bending stiffness.Results: D+Storm showed the lowest tracking forces while the conformability of the Wingspan stent was superior to that of the tested stents. Pro-Kinetic Energy and D+Storm had better wall apposition in curved vessels than the Wingspan stent. Bending stiffness of the Wingspan stent was notably lower, whereas no significant differences were found between D+Storm and Energy. Pro-Kinetic Energy and D+Storm not only indicated lower gap ratios between the struts and the vessel wall but also maintained good wall apposition even in the curved model.Conclusion: These bench-top measurements may provide clinicians with useful information in regard to selecting suitable stents for treatment of intracranial atherosclerotic stenosis.
Is ESG Disclosure a Means to Respond to Catastrophic Events? A Case Study Analysis
Authors: Marrone Arcangelo , Oliva Lara
Published: October 2020

According to the legitimacy theory, disclosure can be considered as a tool for responding to the changing perceptions of a company's stakeholders. Based on this theory, this study, through a case study, examines the reaction of companies in terms of environmental, social, and governance (ESG) disclosure to catastrophic events that have a negative effect on the corporate image. Specifically, this study examines the integrated reports provided by Atlantia in the two years preceding the collapse of the Morandi bridge and in the year of the catastrophic event. The results, however, do not demonstrate significant changes to the ESG disclosure by Atlantia following the catastrophic event. The changes made can in fact be considered as a normal evolution of disclosure policies and not as an attempt to repair the lost legitimacy.

Best ${L^p}$-approximation of generalized biaxially symmetric potentials over Carath'eodory domains in ${C^N}$ having slow growth
Authors: Kumar Devendra
Published: October 2020

Let $ F$ be a real valued generalized biaxially symmetric potentials (GBASP) defined on the Caratheodory domain on $ C^N$. Let $ L_\mu^p(D)$ be the class of all functions $ F$ holomorphic on $ D$ such that $ \parallel F\parallel_{D,p}=[\int_D\mid F\mid^pd\mu]^{1\over p}$. Where $ \mu$ is the positive finite, Boral measure with regular asymptotic distribution on $ C^N$. For $ F\in L_{\mu}^p(D)$, set $ E_n^p(F)=\inf\{\parallel F-P\parallel_{D,p}:P\in H_n\}$, $ H_n$ consist of all real biaxisymmetric harmonic polynomials of degree at most $ 2n$. The paper deals with the growth of entire function GBASP in terms of approximation error in $ L_{\mu}^p$-norm on $ D$. The analysis utilizes the Bergman and Gilbert integral operator method to extend results from classical function theory on the best polynomial approximation of analytic functions of several complex variables. Finally we prove a generalized decomposition theorem in a new way. The paper is the generalization of the concepts of generalized growth parameters to entire functions on Caratheodory domains on $ C^N$ (instead of entire holomorphic functions on $ C$) for slow growth.

COMPARATIVO ENTRE CUSTOS OPERACIONAIS NA POTABILIZAÇÃO DE ÁGUAS SUPERFICIAIS E SUBTERRÂNEAS EM PEQUENAS CIDADES
Authors: Ribeiro Paulo Filho Machado , Melo Marília Carvalho de
Published: October 2020

A água constitui, um elemento de grande necessidade à manutenção da vida, além de ser considerada o composto mais abundante em nosso planeta, ocupando aproximadamente 70% da superfície do mesmo. No entanto, 97% desta água é salgada e, portanto, imprópria ou com grande dificuldade de torna-la própria para o consumo humano. Menos de 3% da água do planeta é doce, das quais 2,5% está em geleiras e os outros 0,5% de água restantes no mundo em águas superficiais ou subterrâneas. Atualmente os mananciais subterrâneos, devido a qualidade da água bruta que geralmente apresenta baixa variabilidade qualitativa, têm se mostrado uma boa alternativa como fonte de água potável, principalmente em comunidades que possuem indisponibilidade ou que precisam incrementar seus sistemas de tratamento, normalmente exclusivamente superficiais, com novas fontes de águas provenientes de mananciais subterrâneos. Sendo assim, este trabalho irá apresentar resultados obtidos a partir de uma análise econômica dos custos com tratamento de água potável para cidades localizadas dentro do território do estado de Minas Gerais e com população menor que 5.000 habitantes. As análises foram realizadas comparando os custos mensais de mão de obra e eletricidade em sistemas de tratamento da água com tipos distintos de mananciais, superficial e subterrâneo.

As tecnologias vieram para alterar e dinamizar o ritmo com que a sociedade se desenvolve e alterar as relações sociais, tendendo a ultrapassar fronteiras e não ficando restritas a um determinado grupamento. Assim, dessa forma, a Uber alcançou espaço entre os consumidores brasileiros a partir de uma mudança social, política e econômica que não ficou adstrito somente a um determinado país, mas tem se alastrado por todos os países do globo, mesmo trazendo controvérsias. O presente artigo busca analisar o impacto da insegurança jurídica no ordenamento jurídico trabalhista e como - ou se - as divergências existentes entre as decisões judiciais de primeira instância acarretam um possível efeito backlash, trilhando o caminho pelo exame dos institutos do backlash e pelo estudo das decisões judiciais que não reconhecem a existência de relação empregatícia e, por fim, pela aplicabilidade e convergência desses institutos.

Published: October 2020

In the present work, an unsteady analysis is carried out for the thermal characterisation of a firefighter protective clothing. Coupled radiative and conduction heat transfers are considered inside the clothing with a focus on the thermal level on the first skin layer. The protective garment is modelled as a 1D solid medium, featuring three layers of tissues, separated by several air-gaps. A parametric analysis is performed in the aim to predict the effect of conductive and radiative tissue's properties fluctuation on the first skin's layer temperature. The thermal balance equations are written in a finite element (FE) formulation and solved using the COMSOL Multiphysics® software. Predictions were provided for the temperature and heat flux distributions in the fabric, skin, and air-gap as a function of time, as well as the time to receive skin burn injuries. The results obtained were compared with stationary 2-D calculations, and faced to unsteady simulations, based on the finite volume method. A 50% relative reduction in the absorptivity of the skin (in the case of wearing a fine knitted fabric) makes it possible to reduce the surface temperature of the skin to a tolerable value.

The aluminum alloy 5083 is widely used as a structural material in marine applications due to very good corrosion resistance and low temperature mechanical properties. Friction stir welding, being a solid state process, offers several benefits over the traditional fusion welding processes. In this study, 10 mm thick AA5083–H321 plates were successfully friction stir welded and the welds were investigated for corrosion behavior using salt fog corrosion tests. The friction stir welds exhibited more corrosion rate compared to that of the base material. However, the corrosion rate was observed to decrease with increase in time of exposure. The cryogenic treatment was found to improve corrosion resistance of the base material and the welds. Furthermore, the corrosion rate increases with decrease in pH value of the salt solution. By and large, it is determined that the cryogenic treatment advantageously effects the corrosion behavior

In the paper, the spread of intensity of linear positioning table system vibrations is examined and an analysis of their parameters upon applying the theory of covariance functions is carried out. For the investigation, two linear positioning tables were chosen; for them, different lubricants were used: universal lubricant Loctite 8103 and lubricant Braycote 601EF for working in vacuum. The results of measurements of the vibration intensity in four fixed points upon varying the speed of the carriage were recorded on the time scale in form of arrays (matrices). The estimates of cross-covariance functions of the arrays of results of measurements of the digital vibration intensity were calculated. The estimates of auto-covariance functions of single arrays upon changing the quantization interval on the time scale were calculated too. For the calculations, the software developed upon using Matlab7 package of procedures was applied.
Die Gleichheit der Mitgliedstaaten in den Institutionen und Entscheidungsverfahren der Europäischen Union – der rechtliche Rahmen
Authors: Haratsch Andreas
Published: October 2020

Die Europäische Union achtet gemäß Art. 4 Abs. 2 S. 1 EUV die Gleichheit ihrer Mitgliedstaaten vor den Verträgen. Dieser unionsrechtliche Grundsatz verlangt die Anerkennung der statusrechtlichen Gleichheit der Mitgliedstaaten. Gleichwohl finden sich in der Zusammensetzung der Organe und Einrichtungen der Union sowie in den Entscheidungsverfahren zahlreiche differenzierende Regelungen. Der folgende Beitrag spürt diesen Ungleichbehandlungen nach und untersucht die Möglichkeiten, diese Abweichungen von der statusrechtlichen Gleichbehandlung zu rechtfertigen. Als sachgerechte Differenzierungsgründe kommen die Sicherstellung einer effizienten Organarbeit, die Art und der Grad der Betroffenheit der Mitgliedstaaten sowie die Funktion des jeweiligen Organs oder der Einrichtung in Betracht.

Der Beitrag befasst sich mit den Rechtsgrundlagen und der Abwicklungsorganisation der Strukturfondsförderung auf den verschiedenen Europäischen und nationalen Ebenen und aus mitgliedstaatlicher Sicht Deutschlands. Zugleich werden aus dem Blickwinkel der Praxis Hinweise auf mögliche Vereinfachungsoptionen ausgesprochen und ein Ausblick auf die neue Förderperiode ab 2021 gegeben. Die Ausführungen zu den einzelnen Fonds konzentrieren sich nicht nur auf den EFRE, den für Deutschland neben dem Landwirtschaftsfonds ELER wichtigsten Investitionsfonds der Europäischen Struktur- und Investitionsfonds (sog. ESI-Fonds). Der Beitrag will vielmehr einen Überblick über die wesentlichen rechtlichen Anforderungen der ESI-Fördermittelvergabe geben und einige Unterschiede in den Verwaltungs- und Kontrollmechanismen der einzelnen Fonds aufzeigen.
Das Berichtswesen der Landesverwaltung NRW: Eine empirische Analyse des Haushaltsplans

Published: October 2020

Der Haushaltsplan ist das zentrale Instrument der öffentlichen Hand zur Planung-, Steuerung- und Kontrolle ihrer Tätigkeiten. Die durch die Verwaltungsreform angestoßene Veränderung der Buchführung und des Berichtswesens sollen zukünftig eine stärkere betriebswirtschaftliche Steuerung der Verwaltungseinheiten ermöglichen. Ziel des Beitrags ist es, zunächst einen Überblick über den Status quo des Berichtswesens in der öffentlichen Verwaltung zu geben, um darauf aufbauend zu analysieren, welche Optimierungspotenziale für das Berichtswesen, am Beispiel des Bundeslandes NRW, bestehen. Hierbei wird die Sichtweise des Controllings als zentrale Unterstützungseinheit dieser Aufgabe eingenommen. Es wird aufgezeigt, dass der Haushaltsplan nach wie vor inputorientiert ist und einen starken Bezug zum kameralistischen System aufweist. Die Umsetzung betriebswirtschaftlicher Mess- und Kennzahlenmodelle unterbleibt weitestgehend. Im Ergebnis wird konstatiert, dass in der öffentlichen Verwaltung ein erhebliches Verbesserungspotenzial bei der Aufbereitung des Berichtswesens existiert.
Der Investorendialog des Aufsichtsrats

Published: October 2020

Can the supervisory board engage in confidential discussions with investors? Or would the authority of the management board and the principle of shareholder equality conflict with this? The work substantiates the dialogue competence of the supervisory board and examines the practical implementation. The author suggests the application of a principle-exception relationship in order to shape the selection of interlocutors in accordance with the leadership authority of the management board. In reference to the principle of shareholder equality, the work examines the narrowing of the dialogue to institutional investors advocated by the literature. It concludes with the draft of a communication regulation for listed companies.
Mode-I and Mode-II Crack Tip Fields in Implicit Gradient Elasticity Based on Laplacians of Stress and Strain. Part II: Asymptotic Solutions
Authors: Broese Carsten , Frischmann Jan , Tsakmakis Charalampos
Published: October 2020

We develop asymptotic solutions for near-tip fields of Mode-I and Mode-II crack problems and for model responses reflected by implicit gradient elasticity. Especially, a model of gradient elasticity is considered, which is based on Laplacians of stress and strain and turns out to be derivable as a particular case of micromorphic (microstrain) elasticity. While the governing model equations of the crack problems are developed in Part I, the present paper addresses analytical solutions for near-tip fields by using asymptotic expansions of Williams’ type. It is shown that for the assumptions made in Part I, the model does not eliminiate the well-known singularities of classical elasticity. This is in contrast to conclusions made elsewhere, which rely upon different assumptions. However, there are significant differences in comparison to classical elasticity, which are discussed in the paper. For instance, in the case of Mode-II loading conditions, the leading terms of the asymptotic solution for the components of the double stress exhibit the remarkable property that they include two stress intensity factors.
Pharmacogenomics: Overview, Applications, and Recent Developments
Authors: Shukla Rahul
Published: October 2020

Pharmacogenomics is defined as the study of genes and how an individual response is affected due to drugs. Pharmacogenomics is an emerging new branch with combination of both pharmacology (the branch of science that deals with study of drugs) as well as genomics (the branch of science that deals with study of genes) for development of effective doses and safe medications tailored according an individual patient genetic makeup. Human Genome Project is one of the crucial projects in which researchers are developing and learning relation in genes and its effect on the body’s response to medications. Difference in genetic makeup provides difference in effectiveness of medication and in future to predict effectiveness of medication for an individual and to study existence of adverse drug reactions. Besides advancement in the field of science and technology till date pharmacogenomics hangs in infancy. There is limited use of pharmacogenomics, but still, novel approaches are under clinical trials. In near future, pharmacogenomics will enable development of tailor-made therapeutics for treating widespread health problems like neurodegenerative, cardiovascular disorders, HIV, cancer, asthma, etc.
Vegetarianism and Veganism: Conflicts in Everyday Life
Authors: Abonizio Juliana
Published: October 2020

In everyday situations, the experience of being a vegetarian or a vegan occurs within a process of conflict and practices of negotiation involving decisions, refusals, consumption acts, and proximity and distance between people in their relationships, mainly including the family. Many dilemmas result from the inconsistency between theory and difficult practices to be obeyed. To understand how this phenomenon, the chapter uses the interviews with vegetarians considering different alimentary restrictions and data obtained from observation in virtual groups of vegan activists. We have conducted the research between 2015 and 2017 as part of a larger project entitled: The Social Place of Animals in Contemporaneity.

Published: October 2020

This is an observational, descriptive and cross-sectional study that looks into nursing competencies within the surgical area and analyzes the influence of the variables age, years worked and employment relationship on the dependent variable nursing competencies. The Perceived Perioperative Competence Scale-Revised (PPCS-R) questionnaire was applied to nurses in the surgical area of the General University Hospital of Castellón. The variables were processed using ANOVA tests and Pearson’s correlations. A sample of 50 female nurses with a mean age of 41 ± 7.931 years was evaluated. Age and number of years worked were positively related to 11 items of the questionnaire. Regarding the employment relationship, significant differences were found, with the “permanent” employment relationship obtaining the highest mean score [1.040 (p = .018)]. Education and clinical experience were found to contribute to the development of practice. Patient safety was an essential aspect in managing the associated risk in the operating room (OR).
