AbstractThe photoconductivity spectra of PbSnTe(In) epitaxial films are investigated by Fourier spectroscopy in the far infrared range at temperatures from 4.2 to 32.4 K. In addition to interband transitions, subgap features associated with the excitation of impurity-defect states are found in the spectra. The evolution of the spectra with temperature and additional illumination is traced.

AbstractAn unusual decrease in the slope of the upper critical field near T _ c 0 at a gradual increase in the ion implantation dose has been experimentally observed in narrow bridges formed on the base of thin HTSC YBa_2Cu_3O_7 – _ x films, while an increase in the defect concentration usually leads to an increase in the local slope of the phase transition line H _ c 2( T ). In addition, it has been found that the temperature dependence of the upper critical field has a positive curvature near T _ c 0. A possible theoretical interpretation of the results is proposed. It is based on the modified Ginzburg–Landau theory with a nonuniform length of superconducting correlations.
Эффект спинового насоса в системе ферромагнитный изолятор/нормальный металл: простая квантово-механическая модель
Authors: Караштин Е.А.
Published: August 2019

We suggest a simple quantum-mechanical model of the spin pumping effect that appears when the ferromagnetic resonance is excited in a magnetic insulator that has a flat contact with a nonmagnetic metal. The model is based on the solution of Schrodinger equation for conductance electrons in the metal. We show that electron reflection with spin flip at the boundary with the insulator leads to the dc and ac (oscillating with the frequency of microwave field exciting the resonance) spin flow from ferromagnet to insulator. The dc effect is small compared to the ac effect; the small parameter here is the ratio of exchange constant in the ferromagnet to the energy of potential barrier between the metal and insulator which is greater than the Fermi energy. The obtained result agrees to known experimental data. The developed model provides a simple and spectacular insight into the phenomenon roots and allows to make analysis of the effect dependence on the parameters of considered system.

AbstractNanowires (NWs) consisting of Ni/Cu and Co/Cu alternating layers with a diameter of 100 nm and layer thicknesses varying between 10 and 500 nm are prepared by template synthesis in pores of polymer track-etched membranes. Bath compositions and different regimes for pulsed electrodeposition of NWs are explored. A procedure for electrodeposition of NWs using pulses of equal charge is developed. By diminishing the amount of charge per pulse, initially we manage to lower the layer thickness to 10–15 nm, but further diminishing of charge in pulses leads to the blending of elemental composition of adjacent layers and/or formation of rod–shell nanostructures within the NWs. The coercive force (15–30 mT) and residual magnetization of our layered NWs are determined from magnetization measurements. For NWs with a layer thickness of 50–100 nm, the magnetization curves recorded in the out-of-plane and in-plane geometries are similar in shape and have similar parameters. For NWs with thicker layers (250 and 500 nm), magnetization curves are markedly different due to magnetic anisotropy (an easy magnetization axis emerges longitudinally to NWs) and interference between neighboring NWs. Magnetic force microscopy of isolated NWs identifies that the NWs comprise magnetic regions extending over ~100–150 nm. The NW can be partially remagnetized by applying an external magnetic field (+16 mT) longitudinally.

The magnetic properties of heterostructures consisting of two films are investigated: the upper layer is rare-earth intermetallic superlattices consisting of exchange-coupled TbCo2 / FeCo layers, and the lower layer, either epitaxially grown La0.7Sr0.3MnO3 (LSMO) manganite optimally doped with strontium, or an epitaxial film of an iron-yttrium garnet Y3Fe5O12 (YFO). The material (TbCo2 / FeCo) n (TCFC) provides giant magnetostriction, a large value of the magnetomechanical coupling coefficient, controlled induced magnetic anisotropy, and spin-orientational transitions induced by a magnetic field or elastic stresses. Experimental studies have shown that the interlayer interaction of the heterostructure TCFC / LSMO has an antiferromagnetic character. An increase in the FMR line width in the structures was ob-served, caused by the spin current flowing through the interface between two films. In the TCFC/YFO heterostructure, an electric voltage induced in the TCFC intermetallic film was observed, caused by the reverse spin Hall effect under ferromagnetic resonance conditions.

The Lifshitz theory framework is applied to determine the pressure of dispersion forces between metallic and dielectric plates separated by a thin layer of ferrofluid. Numerical computations are performed for the plates made of gold and silica glass and ferrofluid consisting of kerosene and nanoparticles of magnetite at room temperature. For this purpose we have used familiar representations for the dielectric properties of gold and silica glass along the imaginary frequency axis and obtained respective representations for magnetite and kerosene. The pressure of dispersion forces was investigated as the function of separation between the plates, of the volume fraction of magnetite particles in a ferrofluid and of their diameter. At sufficiently large separations between the plates simple analytic expressions for this pressure are derived. We discuss possible applications of the obtained results.

Polymer luminescent compositions based on polystyrene (PS), polycarbonate (PC) and polymethyl methacrylate (PMMA) doped with boron difluoride dibenzoylmethanate (DBMBF2), boron difluoride anthracenoylacetonate (AntAcBF2) and their mixture were investigated. Composition based on PS has a maximum quantum yield of luminescence. The role of PS in increasing the efficiency of energy transfer from the donor (DBMBF2) to the acceptor (AntAcBF2) is revealed, which is due to the formation of exciplexes between DBMBF2 and phenyl rings of PS.

We have established that increase in magnesium concentration in LiNbO3:Mg(0.19-5.91 mol% MgO) crystals leads to re-structuring in defective structure and optical anomalies connected with the re-structuring. The anomalies have threshold character. Optical uniformity of crystals was shown to increase at Mg concentration close to a threshold one ~3.0 mol% MgO. IR-absorption spectrum in the area of stretching vibrations of OH groups shifts to a high-frequency area (~50 cm-1 in comparison with other crystals), when Mg concentration nears the second threshold. At this sharp decrease in protons amount and jump-like shift of an absorption edge in the shortwave region are also observed. The shift was shown to be caused by the fact that at 5.5 mol% MgO all point defects NbLi are substitutes by Mg cations and with an increase in Mg concentration, Mg cations occupy Li and Nb sites forming point defects MgLi and MgNb.

The effect of photoinduced processes on the CdSe/ZnS quantum dots surface on the functionality of TiO2 nanoparticles/quantum dots hybrid structures has been studied. We demonstrate that pre-irradiation of QDs layers allows for a threefold increase in the photoinduced electron transfer efficiency in the structures. It was shown that photoinduced processes affect both the efficiency of nonradiative processes in QDs and electron transfer conditions in hybrid structures.

Basel IV A gloomy future for Expected Shortfall risk models. Evidence from the Mexican Stock Market
Authors: Rossignolo Adrián F.
Published: August 2019

To determine the sufficiency of Minimum Capital Requirements (MCR) in Basel IV during financial crises in the Mexican stock market, the paper performs a structural simulation encompassing both the Standardised (SA) and Internal Models Approach (IMA) employing different modelling techniques. The study finds an excessive increase in MCR even in abnormal slumps, furthermore stressing that SA establishes a high floor and only super-leptokurtic models are able to pass its stringent validation standards. Therefore, it is recommended that elements in SA be adaptable to avoid unnecessary capital largeness and the evaluation of the IMA and its interaction with SA revised. Although the outcomes strongly suggest the need to perform adjustments in the regulations, further tests on more markets could help bolster the results, despite the study ranking among the first to assess the adequacy and interplay between Basel IV’s two approaches in Latin American emerging markets. The upshot indicates that Basel IV renders high MCR even for huge falls, placing models at a disadvantage and discouraging its use. The adoption of flexible calibration parameters would align both avenues, facilitating its application.
On the Value of Social Media in Healthcare: A Qualitative Exploration of Uses and Affordances (Preprint)
Authors: Ukoha Chukwuma , Stranieri Andrew
Published: August 2019

BACKGROUND

Social media is increasingly used by healthcare providers. However, despite the growing adoption of the application in healthcare settings, the various contexts of use and the value proposition in each context are not well understood.

OBJECTIVE

This study aimed to explore the uses of social media in healthcare settings and the value proposition in each context of use, using a qualitative methodology. The affordances of social media and how healthcare providers appropriate social media for health-related activities are also explored from a Uses and Gratification Theory perspective.

METHODS

This study is an exploratory qualitative research study. Australian healthcare providers that use social media were contacted to participate in the study. Data was collected through semi-structured interviews and the transcripts were analysed using thematic analysis, to identify common themes expressed across participants.

RESULTS

Nine contexts of use of healthcare social media emerged: professional networking, harnessing patient feedback, public health promotion, professional education, patient education, organizational promotion, crowdsourcing, research, and patient collaboration. Results indicates that healthcare providers are not passive users of information systems, rather, they make conscious decisions regarding if, when and how to use social media. Thus, healthcare providers use social media because they believe that it will help them realize the gratification or value they seek.

CONCLUSIONS

This study conclude that the value of social media in healthcare lie in its potential to support various activities in healthcare settings. However, its value proposition varies depending on context of use.

Reinforcer Efficacy, Response Persistence, and Delay of Reinforcement
Authors: Jarmolowicz David P. , Lattal Kennon A.
Published: August 2019

In an evaluation of the effects of delayed reinforcement on response persistence, two pigeons were exposed to a series of conditions in which reinforcement that either immediately followed or was delayed from the response that produced it alternated across blocks of sessions. Responding was maintained by a progressive-ratio schedule in which the response requirements incremented for successive reinforcers. The effects of signaled and unsignaled delay values of 1, 5, 10, and 20 s were investigated. In general, responding was more persistent, as measured as the point at which responding ceased for 300 s, with shorter delays, regardless of whether the delays were correlated with a distinct stimulus (that is signaled) or not. The results complement earlier findings showing that reinforcement delays affect reinforcer efficacy or response persistence by showing similar effects using an index of response strength that is independent of response rate. They also extend the general effects of delay of reinforcement to a schedule in which they previously have not been demonstrated.

Published: August 2019

Se ha reportado que después de un período de privación el consumo de alimento durante el acceso libre es mayor que el consumo habitual. Este hallazgo conocido como sobre-ingesta o atracón está relacionado con trastornos alimentarios como la bulimia. Se desconoce si este patrón alimentario se presenta cuando la exposición a los períodos de privación es en orden ascendente o descendente. En el presente estudio se investigó el efecto de la duración de los períodos de privación y el orden de exposición a estos períodos, ascendente o descendente, sobre el peso y el consumo de alimento y agua en ratas. Estos datos se compararon con el consumo durante los períodos de acceso libre. Se utilizaron duraciones cortas, i.e., de una a cuatro horas y duraciones largas del período de privación, i.e., de 20 a 23 horas. Se encontró que el peso aumentó independientemente de la duración de la privación. El consumo de alimento fue menor bajo la privación en comparación con los períodos de acceso libre. El consumo de agua siguió el mismo patrón que el consumo de alimento. Se concluye que independientemente del orden de exposición después de los períodos de privación el consumo de alimento es excesivo.
O trabalho infantil indígena sancionado pela diversidade cultural
Authors: Marders Fernanda , Reis Suzéte Da Silva
Published: August 2019

Este estudo, desenvolvido por meio de análise bibliográfica e documental, abordará, primeiramente, a relação do princípio da igualdade no mundo do direito do trabalho, para posteriormente, desenvolver a contínua ocorrência do trabalho infantil, ao longo do tempo e nos dias atuais, desrespeitando a máxima proteção inerente as crianças, conforme precedido no texto constitucional e nas demais legislações. Será necessário desenvolver esse contexto histórico para que seja possível adentrar na questão cultural, que se utiliza como base de autorização para o trabalho infantil indígena, fazendo com que essas crianças sejam descriminadas e que a teoria da proteção integral não seja a elas alcançada. É intuito desse trabalho demonstrar que o trabalho infantil continua a acontecer, inclusive no mundo indígena, mas que faz-se necessário que todas as formas de trabalho infantil sejam erradicadas e que não se conceda, de forma alguma ou em hipótese alguma, objeções para que o trabalho infantil ocorra.

Fundamentos principiológicos para a proibição de publicidade dirigida à criança no Brasil
Authors: Ramos Fabiana D'Andrea , Zanatta Lisiane
Published: August 2019

O presente artigo apresenta, dentro do sistema normativo brasileiro, os fundamentos principiológicos que, para além das regras postas, sustentam a tese da abusividade da atividade publicitária dirigida às crianças. Descreve que a atividade publicitária é atividade econômica amparada pelo fundamento da livre iniciativa e, nessa condição,  está sujeita ao regime constitucional e legal da ordem econômica. Nesse sentido, encontra limitação nos princípios que regem essa disciplina, tais como a dignidade da pessoa humana, a defesa do consumidor e a proteção integral da criança. Na órbita da proteção publicitária do consumidor, a proibição da publicidade dirigida à criança encontra amparo nos princípios da identificação e não abusividade, bem como no da hipervulnerabilidade do consumidor infantil.
Relações contratuais paralelas
Authors: Alves Amauri Cesar
Published: August 2019

No cotidiano do trabalho ocorrem situações em que se sobrepõem múltiplas relações jurídicas. As situações de paralelismo podem dar ensejo a dois contratos de emprego ou a dois contratos de natureza distinta, sendo, neste caso, um de trabalho (sem vínculo empregatício) e outro de emprego. Duas são as espécies do gênero relações contratuais paralelas: relações empregatícias paralelas e relações trabalhistas paralelas.     A definição desenvolvida no presente estudo a respeito do paralelismo contratual tem por cerne a coexistência de dupla avença laborativa entre os mesmos sujeitos contratantes. Assim, há paralelismo contratual nas situações fáticas em que trabalhador e contratante fixam entre si dois pactos jurídicos cujo objeto é o trabalho, podendo haver entre eles dois contratos de emprego (relações empregatícias paralelas) ou um contrato de emprego e outro de trabalho sem vínculo empregatício (relações trabalhistas paralelas). Seja qual for a situação fática, juridicamente deverá o intérprete reconhecer a dupla contratação e preservar os efeitos específicos e distintos que são próprios a cada avença mantida entre os sujeitos da relação paralela.
Natureza jurídica da denúncia anônima dirigida à autoridade pública
Authors: Medeiros Morton Luiz Faria de
Published: August 2019

RESUMOO artigo busca analisar o conceito e a natureza jurídica da denúncia anônima, a partir dos métodos de abordagem hipotético-dedutivo e hermenêutico, por intermédio da interpretação de textos jurídicos extraídos de documentos legislativos, jurisprudenciais e doutrinários. Para tanto, principia-se pela definição de anonimato, investigando-se se a denúncia anônima constitui manifestação da liberdade de expressão ou de manifestação de pensamento, ideia ou opinião, a partir de depuração desses conceitos elementares que a circundam. Embora não haja uniformidade normativa ou doutrinária quanto a delimitações terminológicas para distinguir entre as liberdades de expressão, de manifestação de pensamento, de manifestação de opinião e de imprensa, conclui-se que o direito fundamental de liberdade de manifestação de pensamento é mais abrangente, possuindo dimensões individual (liberdade de expressão) e social (liberdade de prestação de informação), além da modalidade de liberdade de provocação de autoridade pública – em que se enquadram a denúncia anônima e os direitos de petição e de ação, por exemplo. Contudo, se, por um lado, a denúncia anônima não se confunde com o direito de petição – em face de este ostentar caráter político e estar atrelado ao direito a ser informado (o que é dificultado pelo anonimato) – tampouco pode ser equiparado ao direito de ação, que para instaurar processo judicial já demanda um mínimo de elementos de prova.ABSTRACTThis paper analyzes the concept and legal basis of anonymous reporting, using hypothetical-deductive and hermeneutics methods, through the interpretation of legal texts extracted from legislative, doctrine and jurisprudence documents. It begins with the definition of anonymity, investigating whether anonymous report constitutes manifestation of freedom of expression or manifestation of thought, idea or opinion, from the depuration of the elementary concepts that surround it. Although there is no normative or doctrinal uniformity regarding terminological delimitations to distinguish between the freedoms of expression, of expression of thought, of expression of opinion and of the press, it is concluded that the fundamental right of freedom of expression of thought is wider, including individual (Freedom of expression) and social (freedom to provide information) dimensions, in addition to the modality of freedom of provocation of public authority - which include anonymous reporting and petition and action rights, for example. However, if, on the one hand, the anonymous reporting is not the same as the right of petition - because the latter has a political character and is linked to the right to be informed (which is hampered by anonymity), it cannot be the same as the right of action, which in order to institute legal proceedings already requires a minimum of evidence.

Aproximações do modelo de interação entre atividades científicas e valores (Hugh Lacey) à pesquisa jurídica e à valoração moral do Direito (Carlos Santiago Nino)
Authors: Venturi Eliseu Raphael
Published: August 2019

RESUMOO pensamento do filósofo australiano Hugh Lacey dedica-se à realização da crítica da ciência por meio da rejeição do objetivismo positivista (apagamento dos valores na atividade científica) e também do relativismo pós-moderno (indistinção axiológica ou prescindibilidade valorativa). Desta dupla crítica emerge o modelo de interação de valores e práticas científicas e o mundo da vida (M-CV), pelo qual se podem estabelecer estratégias de valoração moral na pesquisa científica. Nesse sentido, pretende-se problematizar o quadro de interação proposto por Lacey, em que se relacionam na mesma abertura analítica as questões epistemológicas e as implicações concretas da ciência – destacando-se, em especial, pressupostos como da crítica da dominação da natureza como valor científico e o dever de instituições e pesquisadores levarem em conta contextos sociais e ecológicos humanos. Relacionam-se a tal teoria objetos e elementos da pesquisa jurídica, em especial pelo apontamento de características de uma possível crise da pesquisa jurídica e pela ênfase no sistema de valoração moral do Direito proposto pelo jurista argentino Carlos Santiago Nino. Pretende-se destacar o pensamento de Lacey a partir das críticas à razão técnica elaboradas por Herbert Marcuse, Karl Popper e Celso Furtado em termos de responsabilidade moral do cientista. Adota-se como metodologia técnicas da pesquisa bibliográfica, com raciocínio dialético entre teoria da pesquisa jurídica e teoria dos valores na ciência.ABSTRACTHugh’s Lacey philosophical work is devoted to the critique of Science through the rejection of positivist objectivism (that erases values in scientific activity) and also of postmodern relativism (axiological indistinction or evalutive dispensability). From this double criticism emerges the model of interaction of values and scientific practices and the lifesworld (M-CV), by which can be established moral valuation strategies in scientific research. In this sense, it is intendend to problematize the interaction framework proposed by Lacey, in which the epistemological issues and the concrete implications of science are related in the same analytic opening – in particular, assumptions such as the critique of the domination of nature as scientific central value and the duty of institutions and researchers to take into account human, social and ecological contexts. This theory relates to objects and elements of legal research, in particular by pointing out characteristics of a possible legal research crisis and by emphasizing the moral value system of Law proposed by the argentine jurist Carlos Santiago Nino. It is intended to highlight Lacey's thinking from the critiques of technical reason elaborated by Herbert Marcuse and Karl Popper in terms of the scientist's moral responsibility. As technical methodology it is used the bibliographical research precepts, with dialectical reasoning between legal research theory and values theory in science.

Regulação e novas tecnologias: o caso das OTTs de Vídeo
Authors: Ragazzo Carlos Emmanuel Joppert , Oliveira Isabel Cristina Veloso de
Published: August 2019

O artigo procura debater a necessidade de atualização da regulação frente ao desenvolvimento de novas tecnologias. Como tema central, trataremos do mercado de TV por assinatura e OTTs, a exemplo da Netflix. A principal pergunta a ser respondida é: Levando em consideração a entrada das OTTs no mercado, a restrição à propriedade cruzada ainda faz sentido? Para responder essa questão, o presente artigo irá explorar, de forma breve, o histórico legislativo e regulatório da restrição da propriedade cruzada em conjunto com uma análise sobre o suposto risco identificado ao mercado na época da imposição da restrição. Ato contínuo, serão analisados dados e funcionalidades do mercado de TV por assinatura em contraste com as inovações, potencialidades, modelo de prestação de serviço e crescimento estrondoso das OTTs de vídeo no Brasil e no mundo, para, ao final, abordar os impactos competitivos e as consequentes assimetrias regulatórias entre os dois modelos (TV por assinatura e OTTs), para sugerir mudanças no modelo regulatório atual.
As dificuldades da implementação do federalismo social na república brasileira
Authors: Amorim Rosendo Freitas de , Martins Francisco Jório Bezerra
Published: August 2019

A República Federativa do Brasil elegeu como direitos supremos, para além da vida, educação, saúde, habitação, dentre outros. A consecução de tais direitos exige um esforço da República para, harmonizando as competências do entes políticos da federação, delinear a atividade de cada um deles na implementação das políticas públicas. Para além de amoldar as ações públicas para a consecução desse fim, exige-se de igual sorte que especialmente o Distrito Federal, os Municípios e os Estados tenham condições financeiras suficientes para mantê-los. No entanto, percebe-se que o nosso federalismo privilegia a União, permitindo-lhe a maior possibilidade de arrecadação, enquanto os demais contratantes do pacto federativo ficam à espera de repasses federais. Desta forma, o federalismo social cooperativo necessita de ajustes para aperfeiçoar as atribuições, bem como operar uma melhor arrecadação a fim de dar efetividade aos direitos e garantias fundamentais, bem como aos direitos sociais.
Sobre uma política criminal baseada na teoria do direito penal do inimigo
Authors: Tangerino Davi De Paiva Costa , Olive Henrique
Published: August 2019

RESUMOEsta apresentação tem por objetivo discutir os instrumentos e problemas relacionados a implementação de uma política criminal baseada em pressupostos da teoria do direito penal do inimigo, desenvolvida mais detalhadamente por Günter Jakobs. Com isto, discute-se tanto a viabilidade, como os limites práticos da atuação do Estado no reconhecimento e na neutralização de riscos. Ainda, abordam-se os pontos elementares da teoria, além de debater as diversas críticas encontradas na bibliografia especializada sobre o tema. Por fim, conclui-se pela existência da utilidade de seus postulados, qual seja, sua utilização como parâmetro para identificação de medidas autoritárias em meio ao sistema democrático. PALAVRAS-CHAVEDireito Penal do Inimigo. Política Criminal. Segurança Pública. Autoritarismo. Estado de Direito.ABSTRACTThis work aims to discuss the instruments and problems related to implementation of a criminal policy based on the directives of the theory of Criminal Law of the Enemy, primarily developed by the German professor Günther Jakobs. Therefore, we discuss the feasibility and the practical limits of the government’s role regarding the identification and nullification of risks, addressing the elements of the theory, then reviewing and debating its critical literature. Finally, this work acknowledges the usefulness of the theory of Criminal Law of the Enemy, that is, its use as a parameter of identification of authoritarian measures within the democratic system.  KEYWORDSCriminal Law of the Enemy.

“Não se fazem mais elites como antigamente”: o incessante problema do elitismo democrático
Authors: Borchert Jens
Published: August 2019

“NÃO SE FAZEM MAIS ELITES COMO ANTIGAMENTE”: O INCESSANTE PROBLEMA DO ELITISMO DEMOCRÁTICO  “THEY AIN’T MAKING ELITES LIKE THEY USED TO”: THE NEVER ENDING TROUBLE WITH DEMOCRATIC ELITISM  RESUMO: Este artigo identifica três princípios centrais do elitismo democrático, da forma como foram desenvolvidos por vários autores. Em seguida, segue a sorte dessas ideias dentro da teoria democrática. Surpreendentemente, eu encontro a aceitação quase universal, embora não reconhecida, dos princípios do elitismo democrático nas teorias contemporâneas da democracia. Entre o público, no entanto, ainda existe um forte anseio por uma democracia mais próxima do ideal e mais aberta à participação pública. Isso se reflete nas críticas públicas a políticos profissionais “distanciados”. Eu argumento que uma solução conceitual para a tensão entre o estado da teoria democrática e as expectativas do público pode, ironicamente, ser fornecida por uma corrente dentro da teoria do elitismo democrático, a saber, a teoria da poliarquia de Robert Dahl. PALAVRAS-CHAVE: teorias da democracia, profissionalismo político, autonomia da elite, participação, competição. ABSTRACT: This article identifies three central tenets of democratic elitism as developed by various authors. It then traces the fate of these ideas within democratic theory. Surprisingly, I find almost universal, if unacknowledged, acceptance of democratic elitism’s principles in contemporary theories of democracy. In the public, however, there is still a strong yearning for a democracy that is closer to the ideal and more open to public participation. This is reflected in public criticisms of “detached” professional politicians. I argue that a conceptual solution to the tension between the state of democratic theory and the public’s expectations may ironically be provided by one strand within the theory of democratic elitism, namely Robert Dahl’s theory of polyarchy.
Accrual and real earnings management in both state-owned and privately-owned Egyptian companies
Authors: Boghdady Ahmed B. A.
Published: August 2019

This study aims to explore the difference between the level of both types of earnings management; Accrual Earnings Management (AEM) and Real Activity Earnings Management (REM)) between state and privately owned Egyptian companies. Using a sample of non-financial state and privately owned companies over the period from 2010 to 2017, with 1030 firm–year observations. The results reveal that there are no significant differences in the level of both AEM and REM using the two proxies; sales manipulation and discretionary expenses; between state and privately owned firms. This result could be attributed to the Egyptian government’s attempt to eliminate the differences between state-owned and private owned companies, especially in recent years.
Continuing Education Online
Authors: Macklin Denise
Published: August 2019

The Internet offers a resource for media-rich training fully capable of evaluation, adaptation, and remediation, which is independent of computer platform, for individuals anywhere in the world, at any time. Interest and usage of the Internet as a source of information are increasing. In the future, as more nurses become comfortable with the Internet and begin to demand Internet learning opportunities, continuing education (CE) offerings will become more prevalent. This article reviews the benefits and limitations of Internet education offerings and the issues that arise in developing an Internet CE site, including the duties of a website administrator and a general overview of the cost of development and revenue generation. As speed and security improve, the Internet is becoming increasingly integrated into everyday life. Infusion therapy offers a unique opportunity because this information is not widely known and is not widely available on the Internet.
Minimizing Sharps Injuries in the UH: Accessing Safer Sharps and Needle-Free Systems
Authors: Gabriel Janice
Published: August 2019

In the United Kingdom (UK) healthcare workers do not have uniform access to safer sharps and needle-free systems in their individual workplaces. The availability of such products is dependent on their budget manager authorizing the purchase of these devices. This can mean that within the same institution one department can be using safer sharps and needle-free systems, while another department does not have access to this equipment. This is partly due to competing priorities for scarce healthcare resources and lack of national guidance to employers to provide such safety equipment for their employees. At the current time the UK does not have a mandatory reporting system for sharps injuries, so the true extent of the problem is not fully understood.
You Are Only as Good as Your Data Developing an Electronic PICC Database
Authors: Costa Nancy
Published: August 2019

The elevation of vascular access to specialty status mandates an increased responsibility for the demonstration of clinical quality and evidence of effectiveness. Although patient outcomes have always been important, the need to capture, qualify, and quantify outcomes has become essential to survival in today's competitive healthcare environment. Data collection and interpretation are integral steps in the ongoing process of outcomes analysis. Standardization in the definition of outcome indicators is imperative for accurate analysis and trending of performances that represent best practice. This article demonstrates how the development of an electronic PICC database can assist the practitioner in providing the evidence for evidence-based practice.

A prospective, randomized comparison of three needleless IV systems used in conjunction with peripherally inserted central catheters
Authors: Buehrle Douglas C.
Published: August 2019

Use of needleless intravenous systems are important in preventing injury and exposure to blood-borne pathogens. After insertion, patients were randomized to have either a PASV Protector, CLC2000, or CLAVE device placed on the hub of the indwelling PICC. Rates of occlusion were 11% with the CLAVE device, 4% with the CLC2000 device, and only 1% with the PASV Protector device. With use of the PASV Protector device, occlusion rates dropped significantly.

Published: August 2019

Infusion Therapy and vascular access devices have had a profound impact on nursing practice over the years. The domain of nursing practice lends itself to providing an open window of opportunity for the nurse to enter different arenas of nursing practice and to develop expertise in a chosen field. That is what happened at the M.D. Anderson Cancer Center, Houston, TX, in the 1970s. This article provides an overview of the history of the Infusion Therapy Team along with current and future practice.
Current Issues in Immunoglobulin Therapies

Published: August 2019

While immunoglobulin therapy has been available in healthcare for many years, the issues related to new brands, product availability, costs and safety continue to change. The shortages of the last ten years and concerns over the transmission of Hepatitis and/or HIV have been replaced with other equally complex and challenging concerns to both patients and clinicians. This article examines the most urgent of those concerns and describes the relevance these issues have to clinical practice.
