Compassion-Focused Therapy (Cft) As An Intervention Against Suicidal Ideation In Newly Diagnosed People Living With Hiv/Aids (Plwha) Attending A Nigerian Maternity Teaching Hospital
Authors: Ogueji A. Ifeanyichukwu , Okoloba M. Maia
Published: May 2020

Objectives

In Sub-Saharan Africa, Nigeria is currently home to many people living with HIV/AIDS (PLWHA), and suicidal ideation is amongst the common early problems of newly diagnosed PLWHA. This reflects the importance of including psychotherapy in HIV care. In this regard, compassion-focused therapy (CFT) is the one that has not been a point of study for reducing suicidal risks in newly diagnosed PLWHA despite the relevance of CFT to the treatment/management of persons living with self-criticism or self-harm. To bridge this gap, we examined the use of CFT as an intervention against suicidal ideation in newly diagnosed PLWHA receiving antiretroviral therapy at the Adeoyo Maternity Teaching Hospital in Ibadan, Oyo state, Nigeria.

Methods

Twenty-two participants (mean age = 40 ± 5.6 years) with less than 1-month-old clinical diagnosis of HIV who have recently thought about suicide because of the new HIV-positive diagnosis were purposively sampled and randomly assigned into the intervention and control groups. The CFT module and scale for suicide ideation were the research instruments. All data collected were analysed using SPSS (v.22.0), and statistical significance was determined at P<0.05.

Results

The findings established that after administering CFT to the intervention group, the mean score for suicidal ideation was significantly lower in the intervention group compared with that in the control group.

Conclusion

The results suggest that CFT has the potential to reduce suicidal ideation in newly diagnosed PLWHA; therefore, in addition to the antiretroviral therapy, the administration of CFT should be included in the early stage of HIV care, to reduce the risk of suicide that is associated with newly living with HIV/AIDS.
On the Verbalization of Space and Direction Concepts
Authors: Kotin Michail L.
Published: May 2020

The paper deals with selected problems of the verbalization of the concepts “place”, “space” and “direction”, with a special consideration of their successive development in language and in language acquisition. The theoretical background are assumptions concerning the genesis of the concept of place and movement. Some of them claim that movement and direction precede the conceptualization of place and space. However, numerous linguistic phenomena seem to prove the opposite hypothesis, namely that the concept of place and, thus, its verbalization by means of stative verbs, local adverbs and prepositional phrases is original, whereas the concepts of movement, especially of controlled, caused movement denoted by transitive, regular verbs is derived from the concept of locum encoded by irregular verbs.

Authors: Miterpáková M. , Zborovská H. , Bielik B. , Halán M.
Published: May 2020

During the past few years, several localities with increasing Dirofilaria immitis occurrences have been identified in Slovakia; particularly in areas regarded as endemic for Dirofilaria repens up until now. In terms of that, dogs with clinically manifested heartworm disease have been referred to the veterinary ambulances more frequently. We report in this study, two autochthonous cases of D. immitisinfections diagnosed in two seven-year-old siblings of Tibetan Mastiff dogs from the Košice region of south-eastern Slovakia. The course of the disease in both dogs were very different. The female dog did not manifest any unusual findings, however the male dog exhibited severe clinical signs of heartworm disease that lead to his death. The subsequent autopsy revealed adult D. immitis worms in the right heart ventricle and pulmonary arteries.

Authors: Michołap Paweł , Sikora Aneta , Pawlikowski Tadeusz E. , Sikora Marcin
Published: May 2020

The aim of the study is to present all distribution sites of Bombus semenoviellus in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the high Karkonosze and Tatry mountains. This is likely the effect of progressing climate change, as well as the increase in climate continentalism in Europe. Differences between summer and winter temperatures favour the spread of this Siberian bumblebee species throughout the continent. Many specimens were found on plants originating from its central and west Asia. Those plants also occur in eastern and central Europe which could have helped this bumblebee spread west throughout Europe. B. semenoviellus will increase its range towards Western Europe. Based on observations so far, it is not possible to determine its invasive features and increased competitiveness for food and nesting places in relation to other bumblebee species.

Published: May 2020

Introduction

Peptic mucosal damage induced by acute stress is a serious cause of morbidity and mortality in critically ill patients. The study aimed to investigate the protective, antioxidant and anti-inflammatory effects of pretreatment with Chios mastic gum (CMG), a traditionally consumed herbal resin naturally deriving from the trunk of Pistacia Lentiscus var. Chia compared to Omeprazole, a standard medication used in the prevention and treatment of gastritis, against the effects of cold restraint stress (CRS) in rat gastric and colonic mucosa.

Methods

Twenty-one male Wistar rats were randomly assigned to three groups: Control (C), Omeprazole (O), and CMG (M), according to the pre-treatment regime, and were subjected to CRS at 40C for 3 hours. The gastric and colonic mucosal lesions were histologically assessed. ELISA measured blood concentrations of TNF-α, IL-1β, peroxidase, superoxide dismutase (SOD) and total antioxidant capacity (TEAC).

Results

In both groups, O and M, gastric mucosal hyperemia, haemorrhagic infiltration and mucosal oedema, as well as colonic mucosal hyperaemia and haemorrhagic infiltration were significantly reduced compared to the controls (p<0.05). No significant differences were observed between Groups O and M. TNF-α levels were significantly lower in group M compared to Group O (p=0.013). IL-1β levels were significantly depressed in groups M and O compared to control (p≤ 0.001). The activity of both peroxidase and SOD enzymes decreased in group M compared to group O (p= 0.043 and p=0.047 respectively) and the control (p=0.018 and p< 0.001 respectively).

Conclusions

The natural Chios mastic gum is a promising nutritional supplement with protective properties to the peptic mucosa against CRS, exerting anti-inflammatory and antioxidant effects.
Innovation-based fractional order adaptive Kalman filter
Authors: Tripathi Ravi Pratap , Singh Ashutosh Kumar , Gangwar Pavan
Published: May 2020

Kalman Filter (KF) is the most widely used estimator to estimate and track the states of target. It works well when noise parameters and system models are well defined in advance. Its performance degrades and starts diverging when noise parameters (mainly measurement noise) changes. In the open literature available researchers has used the concept of Fractional Order Kalman Filter (FOKF) to stabilize the KF. However in the practical application there is a variation in the measurement noise, which will leads to divergence and degradation in the FOKF approach. An Innovation Adaptive Estimation (IAE) based FOKF algorithm is presented in this paper. In order to check the stability of the proposed method, Lyapunov theory is used. Position tracking simulation has been performed for performance evaluation, which shows the better result and robustness.

Authors: Szpytko Janusz , Salgado Duarte Yorlandys
Published: May 2020

A simulation model to evaluate risks in Power Systems including green energy sources to generate electricity for electro mobility use is presented in the paper. The model allows to calculate risk indicator that characterize the performance of the Power Systems. The model considers the additional risks of wind and solar variability in the Power Systems, through wind farms and PV farms, respectively. Also, in the recent years, the number of electric vehicles (EVs) on the road have been rapidly increasing. Charging this increasing number of EVs is expected to have an impact on the power grid especially if high charging powers and opportunistic charging are used. Multiple papers have observed that the charging stations are used by multiple users during the day. In a context where electric mobility is gaining increasing importance as a more sustainable solution for urban environments, this work presents the optimization of charging profiles of the potential users of these charging stations. We analyzed the charging profiles in a power grid with renewables sources of energy and we determine the optimal charging profiles for the power grid based on maximizing the energy delivered by renewable sources of energy.
Thermal Stress in Concrete Slab of the Airfield Pavement
Authors: Linek Małgorzata , Nita Piotr
Published: May 2020

Stress occurring in concrete pavement slab changes on daily and annual basis. Daily changes of air temperature in between environments depend on the following: latitude where the structure is located and season. Change of air temperature causes the variable thermal stress of a slab and consequently change of its linear dimensions (slab extension or shortening. “Thermal balance of pavement” prepared for individual structure solutions, should be the basis for construction design and geometric solutions concerning air field structure. This publication refers only to natural changes of temperature conditions of the environment. Other phenomena occurring on concrete airfield pavement under the influence of imposed thermal loads will be the subject of another publication in this regard.

Authors: Sedghi Arman , Salehkooh Elham Akbari , Chadorbafzade Monireh
Published: May 2020

Nickel-cobalt ferrite spinels are ferrimagnetic ceramic materials that possess a great potential for application in highdensity magnetic media, recording, color imaging, ferrofluids, and high-frequency devices. A change of their structure from micro- to nano- improves their properties drastically, therefore many methods have been investigated to fabricate nanopowder of these spinels. Gel combustion method is one of them. In this research, Ni0 5Co0 5Fe2O4 nanoparticles were fabricated via gel combustion method using metallic nitrates as an oxidant and citric acid, glycine and urea as fuels and the effects of fuel type on the reaction behavior, structure and morphology of Ni0 5Co0 5Fe2O4 nanoparticles were investigated. The reaction behavior was studied by thermal analysis method (TGA-DTA), crystallite size of powders was characterized by X-ray diffraction (XRD) and their morphology was studied by FE-SEM. The results revealed that the reaction was initiated in urea, glycine and citric at 219 °C, 197 °C, 212 °C, respectively. Samples fabricated from glycine and citric acid had a pure spinel structure but the others fabricated with urea fuel had iron oxide impurity. The crystallite size of nickel cobalt ferrite nanoparticles was in the range of 58 nm to 64 nm and the nanoparticles were agglomerated.

Published: May 2020

Nanoparticles of Li2MnO3 were fabricated by sol-gel method using precursors of lithium acetate and manganese acetate, and citric acid as chelating agent in the stoichiometric ratio. TGA/DTA measurements of the sample in the regions of 30 °C to 176 °C, 176 °C to 422 °C and 422 °C to 462 °C were taken to identify the decomposition temperature and weight loss. The XRD analysis of the sample indicates that the synthesized material is monoclinic crystalline in nature and the calculated lattice parameters are 4.928 Å (a), 8.533 Å (b), and 9.604 Å (c). The surface morphology, particle size and elemental analysis of the samples were observed using SEM and EDAX techniques and the results confirmed the agglomeration of nanoparticles and, as expected, Li2MnO3 composition. Half cells of Li2MnO3 were assembled and tested at C/10 rate and the maximum capacity of 27 mAh/g was obtained. Charging and discharging processes that occurred at 3 V and 4 V were clearly observed from the cyclic voltammetric experiments. Stability of the electrodes was confirmed by the perfect reversibility of the anodic and cathodic peak positions observed in the cyclic voltammogram of the sample. The Li2MnO3 nanoparticles exhibit excellent properties and they are suitable for cathode materials in lithium ion batteries.
How Eurosceptic is Fidesz actually?
Authors: Hargitai Tibor
Published: May 2020

Until now there is no consensus in the academic literature as to whether Fidesz is a (soft) Eurosceptic party or rather Europragmatic. By identifying the manifestations of Euroscepticism on the policy level rather than the party level, this article sheds light on the dynamics of Fidesz’s Euroscepticism. It also looks at the party strategy of Fidesz regarding its main Eurosceptic competitor Jobbik, and how this facilitated further Euroscepticism. Hungary’s vision of the EU is at odds with the vision of most member states and EU institutions, which makes Fidesz not only Eurosceptic; but there is a form of inverted soft Euroscepticism characterising Fidesz’s vision and policies towards the EU.
Trajectories of social democracy in the Baltic countries: choices and constraints
Authors: Gudžinskas Liutauras
Published: May 2020

This article focuses on social democratic parties in the Baltic states. The evolution of the democratic left in these countries deviates from more researched cases of social democratic parties in the Visegrád countries. Although the Lithuanian Social Democratic party (LSDP) had been developing in a similar way to its counterparts in Hungary, Poland and Czechia, its efforts to rebound after a crushing defeat in the 2016 parliamentary elections have proved to be far more successful. Meanwhile, Estonian and Latvian Social Democrats from the outset had to compete under the prevalence of right-wing parties in highly heterogenous societies. However, despite similar initial conditions, their eventual trajectories crucially diverged. Hence, a research puzzle is double: how to explain LSDP’s deviation from similar Visegrád cases, and what are the main factors that led to the differentiation of Estonian and Latvian social democratic parties? While the current research literature tends to emphasise structural and external causes, this paper applies an organisational approach to explain the different fortunes of the democratic left in the Baltic countries as well as other East-Central European states.
Polish Regional Elite Career Paths and the Impact of a Multilevel System
Authors: Majchierkiewicz Tatiana
Published: May 2020

This paper aims to investigate the multilevel careers of members of Polish regional executives from the first direct election to regional parliaments in 1998 until the end of 2014. Formation of self-government in regions is assumed to have started the process of formation of the multilevel system in Poland. Consequently, political career paths began to be diversified and to take place at more than one level. Among the factors with a critical impact on the specificity of Polish regional careers was the fact that regionalisation was preceded by local government reform (1990), and it was assumed that the local elite would become its natural recruitment base. On the one hand, the challenge to the development of the multilevel system has to be recognised. First, regional politics has undergone rather limited professionalisation (only positions in regional executives are full-time political jobs). Second, the legacy of communist centralisation resulted in lukewarm regional decentralisation in 1998. However, one can observe a certain increased prominence of self-government due to access to EU funds and increased financial autonomy. Positions in regional executive boards, especially as heads of regional boards [marszałkowie], have been seen as increasingly attractive career choices for professional politicians. Therefore, modification of the traditional career model is expected, e.g. some inflow of national politicians into regional boards (from positions in the legislature to executive posts).
Identity according to Francis Fukuyama: An obstacle to the end of history
Authors: Paďour František
Published: May 2020

This review essay focuses on Francis Fukuyama’s book Identity: The Demand for Dignity and the Politics of Resentment, which was published in 2018. The text emphasises placing Fukuyama’s new publication in the context of his multi-year work for its correct interpretation. Fukuyama’s conception of the human soul is analysed in confrontation with contemporary issues of liberal democracy. It mentions other authors criticisms of Fukuyama’s work and, at the same time, it is defended by Fukuyama himself. The text can be seen as an introduction to Francis Fukuyama’s reasoning regarding the modern problems of liberal democracy and as an attempt to understand his unsuccessful prediction of the end of history. The central theme of the text is the concept of identity, which Fukuyama describes as a source of conflicts and friction areas in modern societies. Fukuyama’s findings are supplemented by the findings of other authors and current world events.

Three-phase partitioning (TPP) was used to purify plant-esterase from wheat flour. Effect of various process parameters has been evaluated and plant-esterase was purified to 11.35-fold by optimized single step TPP system (50%, (w/v) (NH4)2SO4 saturation, 1:1 (v/v) ratio of crude extract: t-butanol at pH 4).The enzyme was found to be exclusively partitioned in the aqueous phase. Using TPP system, plant-esterase quickly purified to homogeneity with very high purity and activity. On the basis of single factor research, purification process was optimized by using response surface method, established a new type of high efficient purification plant-esterase method. To the best of our knowledge, this is the first report for purification and characterization of plant-esterase by using three phase partitioning (TPP). The results indicated that, TPP is a simple, quick, economical and very attractive process for purification of plant-esterase compared to conventional chromatographic protocols.
Conversion coefficients from fluence and air kerma to personal dose equivalent for monoenergetic photons using analytical fit and Monte Carlo simulation
Authors: Kanti Hassan Al , Hajjaji O. El , Bardouni T. El
Published: May 2020

The present study aims to calculate a new database of conversion coefficients from fluence and air Kerma to personal dose equivalent in two terms: absorbed dose and Kerma-approximations. In this work, we propose a new equation to perform an analytical fit of our Monte Carlo (MC) calculated conversion coefficients for photons for different angles. Also, we have calculated the conversion coefficients using the EGSnrc code. The conversion coefficients have been calculated for beams of monoenergetic photons from 0.015 to 10 MeV, incident on phantom ICRU for angles of incidence from 0° to a 75° in steps of 15°. Our computed values agree well when compared with those published for the ICRU 57 in Kerma-approximations with statistical uncertainties in the calculation around 2%. We can conclude from this work that the analytical approach is successful and powerful such as Monte Carlo methods to calculate the operational quantities.
Calculation of the Dynamic Characteristics of Ship’s Aft Stern Tube Bearing Considering Journal Deflection
Authors: Yang Hongjun , Li Jun , Li Xiaolong
Published: May 2020

Dynamic properties are vital for the working reliability of aft stern tube bearings. However, the determination of such properties currently involves several simplifications and assumptions. To obtain its dynamic characteristics accurately, the aft stern tube bearing was divided into several bearing segments. The oil film reaction force was considered in the calculation of shaft alignment, and the journal deflection and actual oil film thickness were obtained accordingly. Subsequently, the perturbed Reynolds equation was solved using the finite difference method when the dynamic characteristics of journal bearings with finite width were evaluated. Then, a calculation program was developed and verified by comparing with the results of other studies. Finally, the dynamic characteristics were calculated under different revolutions. The results showed that the stiffness at the vertical direction of the aft stern tube bearing was several times that of the horizontal direction and varied with the revolutions of the shafting system. These findings can provide the foundation for the precise calculation of the journal trajectory under dynamic conditions, as well as for the evaluation of the oil film thickness. Moreover, the results led to favorable conditions for the accurate calculation of the shafting whirling vibration.
A Comparative Measurement Study of Web Tracking on Mobile and Desktop Environments
Authors: Yang Zhiju , Yue Chuan
Published: May 2020

Web measurement is a powerful approach to studying various tracking practices that may compromise the privacy of millions of users. Researchers have built several measurement frameworks and performed a few studies to measure web tracking on the desktop environment. However, little is known about web tracking on the mobile environment, and no tool is readily available for performing a comparative measurement study on mobile and desktop environments. In this work, we built a framework called WTPatrol that allows us and other researchers to perform web tracking measurement on both mobile and desktop environments. Using WTPatrol, we performed the first comparative measurement study of web tracking on 23,310 websites that have both mobile version and desktop version web-pages. We conducted an in-depth comparison of the web tracking practices of those websites between mobile and desktop environments from two perspectives: web tracking based on JavaScript APIs and web tracking based on HTTP cookies. Overall, we found that mobile web tracking has its unique characteristics especially due to mobile-specific trackers, and it has become increasingly as prevalent as desktop web tracking. However, the potential impact of mobile web tracking is more severe than that of desktop web tracking because a user may use a mobile device frequently in different places and be continuously tracked. We further gave some suggestions to web users, developers, and researchers to defend against web tracking.
Secure and Scalable Document Similarity on Distributed Databases: Differential Privacy to the Rescue
Authors: Schoppmann Phillipp , Vogelsang Lennart , Gascón Adrià , Balle Borja
Published: May 2020

Privacy-preserving collaborative data analysis enables richer models than what each party can learn with their own data. Secure Multi-Party Computation (MPC) offers a robust cryptographic approach to this problem, and in fact several protocols have been proposed for various data analysis and machine learning tasks. In this work, we focus on secure similarity computation between text documents, and the application to k-nearest neighbors (k-NN) classification. Due to its non-parametric nature, k-NN presents scalability challenges in the MPC setting. Previous work addresses these by introducing non-standard assumptions about the abilities of an attacker, for example by relying on non-colluding servers. In this work, we tackle the scalability challenge from a different angle, and instead introduce a secure preprocessing phase that reveals differentially private (DP) statistics about the data. This allows us to exploit the inherent sparsity of text data and significantly speed up all subsequent classifications.
T0RTT: Non-Interactive Immediate Forward-Secret Single-Pass Circuit Construction
Authors: Lauer Sebastian , Gellert Kai , Merget Robert , Handirk Tobias , Schwenk Jörg
Published: May 2020

Maintaining privacy on the Internet with the presence of powerful adversaries such as nation-state attackers is a challenging topic, and the Tor project is currently the most important tool to protect against this threat. The circuit construction protocol (CCP) negotiates cryptographic keys for Tor circuits, which overlay TCP/IP by routing Tor cells over n onion routers. The current circuit construction protocol provides strong security guarantees such as forward secrecy by exchanging 𝒪(n
2) messages.

For several years it has been an open question if the same strong security guarantees could be achieved with less message overhead, which is desirable because of the inherent latency in overlay networks. Several publications described CCPs which require only 𝒪(n) message exchanges, but significantly reduce the security of the resulting Tor circuit. It was even conjectured that it is impossible to achieve both message complexity 𝒪(n) and forward secrecy immediately after circuit construction (so-called immediate forward secrecy). Inspired by the latest advancements in zero round-trip time key exchange (0-RTT), we present a new CCP protocol Tor 0-RTT (T0RTT). Using modern cryptographic primitives such as puncturable encryption allow to achieve immediate forward secrecy using only 𝒪(n) messages. We implemented these new primitives to give a first indication of possible problems and how to overcome them in order to build practical CCPs with 𝒪(n) messages and immediate forward secrecy in the future.

Published: May 2020

The article examines agro-technical requirements of machine implements with disk working bodies and is aimed to investigate the existing and alternative methods of depth regulation during soil tillage by the mentioned implements. We defined the machines performance indicators significantly affecting the plant potential release not considered previously. The study results were obtained via the soil tilling depth regulation by the disking speed, the change of an incidence angle of the working batteries, and by the use of the additional load mounted on the machine frame. The article presents a two-year research results obtained in 40 different land plots of the Sumy region (Ukraine) using domestic and imported machines, with wheat and buckwheat as crops. To ensure the study accuracy, the methodology was based on the CND 46.16.02.-96. Agricultural Machinery. Quality Indicators Nomenclature (Catalogue of Normative Documents, published in 1997). The research results demonstrate that the tilling depth depends on the manufacturing plant default settings, the speed regime, and the machine load. For the experimental data analysis, the Least Squares Means method was used. The research presents alternative methods of changing the tilling depth applicable for any machine aggregates with disk working bodies, and its results can serve the agricultural machinery designers.
The Recuperative Heat Exchangers – The Mean Temperature Difference in the Special Cases of Heat Transfer
Authors: Štefan Gužela , František Dzianik
Published: May 2020

The heat exchangers are used to heat or cool the material streams. To calculate the heat exchanger, it is important to know the type of heat exchanger and its operating characteristic. This characteristic determines one of the key variables (e.g., F, NTUmin, or θ). In some special cases, it is not necessary to know its operating characteristic to calculate the heat exchanger. This article deals with these special cases. The article also contains a general dependency that allows checking the key variables related to a given heat exchanger.

A Micro-Level Investigation of Optimum Lime-Content Stabilized Expansive Soil Amended with Organic Coconut Shell Powder
Authors: James Jijo
Published: May 2020

The experimental investigation involved stabilizing an expansive soil using lime, amending the stabilization process with varying doses of coconut shell powder (CSP), and studying the effects of the amendment on the strength, index properties, mineralogy, and microstructure of the stabilized soil. The optimum lime content (OLC) for the maximum strength gain of the stabilized soil was determined by performing unconfined compressive strength (UCS) tests. The stabilization process was amended with four different proportions of CSP, and the UCSs of the amended specimens were evaluated and compared. The spent UCS samples were crushed and pulverized to perform index property tests as well as mineralogical (XRD) and micro-structural (SEM) tests. The results of the investigation revealed that amending the lime stabilization process with CSP yielded positive results only at a low dosage of 0.25%. It is concluded that materials of an organic origin such as CSP need to be adopted in low dosages to reap beneficial effects in the stabilization process.
Causality Between Public Debt, Public Debt Service and Economic Growth in an Emerging Economy
Authors: Saungweme Talknice , Odhiambo Nicholas M.
Published: May 2020

This paper explores the causality between public debt, public debt service and economic growth in South Africa covering the period 1970 – 2017. The study employs the autoregressive distributed lag (ARDL) bounds testing approach to cointegration and the multivariate Granger-causality test. The empirical results indicate that there is unidirectional causality from economic growth to public debt, but only in the short run. However, the study fails to establish any causality between public debt service and economic growth, both in the short run and long run. In line with the empirical evidence, the study concludes that it is economic growth that drives public debt in South Africa, and that the causal relationship between public debt and economic growth is sensitive to the timeframe considered. The paper recommends policymakers in South Africa to consider growth-enhancing policies in the short run, since poor economic performances may lead to high public debt levels.

Authors: Ologbenla Patrick
Published: May 2020

The study investigates the nexus between military expenditure and macroeconomic performance in Nigeria between 1980 and 2017. Data on military expenditure and some macroeconomic variables such as output (GDP), exchange rate and inflation rate are used in the study. The Vector Auto-regression technique VAR is applied so as to study the interactions among the variables in the short run. The result shows that military expenditure in Nigeria is significantly influenced by output and exchange rate shocks. It was also revealed that military expenditure does not make significant contributions to the behaviour of output in Nigeria. Military expenditure appears to be insulated against inflation shock since the largest chunk of military expenditure is traded in foreign currency hence less affected by domestic prices.

In this paper we study the convergence model of interest rates by Corzo and Schwartz. It models the situation when a country is going to enter a monetary union, for example the eurozone. We are interested in estimating the underlying short rate, which is a theoretical variable, not observed on the market. We use the procedure already employed for the Vasicek model to the eurozone data and for the case of a zero correlation we show that a similar procedure can be used also for the estimation of the domestic parameters and the short rate values. The assumption of the zero correlation allows us to simplify the optimization problem, but using simulations we show that our algorithm is robust to the specification of the correlation. It estimates the short rate with a high precision also in the original case of a nonzero correlation, as well as in the case of a dynamic correlation, when the correlation is modelled as a function of time. Finally, we use the algorithm to real market data and estimate the short rate before adoption of the euro currency in Slovakia, Estonia, Latvia and Lithuania.

The COVID-19 pandemic and resulting shutdowns are affecting every aspect of society. The legal profession and the justice system have been profoundly disrupted at precisely the time when there is an unprecedented need for legal services to deal with a host of legal issues generated by the pandemic, including disaster relief, health law, insurance, labor law, criminal justice, domestic violence, and civil rights. The need for lawyers to address these issues is great but the prospect of licensing new lawyers is challenging due to the serious health consequences of administering the bar examination during the pandemic.

State Supreme Courts are actively considering alternative paths to licensure. One such alternative is the diploma privilege, a path to licensure currently used only in Wisconsin. Wisconsin’s privilege, limited to graduates of its two in-state schools, has triggered constitutional challenges never fully resolved by the lower courts. As states consider emergency diploma privileges to address the pandemic, they will face these unresolved constitutional issues.

This Article explores those constitutional challenges and concludes that a diploma privilege limited to graduates of in-state schools raises serious Dormant Commerce Clause questions that will require the state to tie the privilege to the particular competencies in-state students develop and avenues they have to demonstrate those competencies to the state’s practicing bar over three years. Meeting that standard will be particularly difficult if a state adopts an in-state privilege on an emergency basis. States should consider other options, including privileges that do not prefer in-state schools. The analysis is important both for states considering emergency measures and for those that might restructure their licensing after the pandemic.

Os medicamentos psicotrópicos são substâncias que atuam no sistema nervoso central (SNC) usados no tratamento de distúrbios psíquicos. Esses medicamentos têm seu uso de controle especial com a Portaria n.º 344/98 para a venda ou distribuição na rede pública, que requerem um olhar mais atencioso pelas autoridades e profissionais de saúde, devido aos diversos efeitos causados, principalmente o da dependência psíquica. Neste contexto, este estudo teve como objetivo conhecer o perfil sociodemográfico e as classes de psicotrópicos mais consumidas pelos pacientes atendidos no Centro de Atenção Psicossocial do município de Guaraciaba do Norte-CE. Realizou-se um estudo observacional, transversal e descritivo com abordagem quantitativa com aplicação do questionário. Os resultados mostraram que as mulheres (56%; n=28) utilizam os medicamentos psicotrópicos com maior frequência que os homens (44%; n= 22), a faixa etária em evidência foi 31 a 40 anos (32%; n= 16), a maioria dos entrevistados são casados (40%; n= 20), não completaram o ensino fundamental (52%; n= 26) e tem como profissão do lar (30%; n= 15). A classe medicamentosa mais utilizada foi a dos antidepressivos (32%; n=16). Metade dos pacientes entrevistados apresentaram reações adversas (50%; n= 25). Espera-se com esses resultados contribuir no planejamento das ações de saúde destinada aos portadores de doenças psiquiátricas, e servir de alerta aos usuários de substâncias psicotrópicas, e aos gestores para que possam melhorar as políticas de saúde mental do município.

A história da saúde no Brasil é resultado de inúmeras disputas que transpassam por conquistas políticas, pela organização e participação social. A participação da sociedade em processos políticos surgiu a partir de 1948, através da Declaração Universal dos Direitos Humanos, em que proclamou o direito à saúde. O estudo objetiva relatar a experiência de acadêmicos de enfermagem durante visita técnica à uma associação comunitária que presta serviço assistencial em saúde. Trata-se de um relato de experiência, sobre a vivência de acadêmicos do Curso de Graduação em Enfermagem do Centro Universitário Católica de Quixadá, em uma visita técnica à uma Associação não governamental e sem fins lucrativos. Na oportunidade prestou-se assistência a um grupo de mulheres assistidas na referida associação, através da realização de consultas de Enfermagem no aspecto do pré-natal e exames preventivos. Além disso, ocorreu uma educação em saúde para 12 gestantes que estavam na instituição naquele momento, com duração de 20 minutos, no qual foi abordado: patologias mamárias, câncer ginecológico e exame de Papanicolau. Inicialmente foi realizado as consultas de Enfermagem, referente ao pré-natal e exames preventivos, incluindo exame clínico das mamas e o exame Papanicolaou. Durante os atendimentos foi realizado convite as gestantes para participarem de uma estratégia educativa que ocorreu posteriormente as consultas. Conclui-se que o fomento às alianças comunitárias faz-se essencial, para que assim indivíduos agindo de forma autônoma sejam capazes de refletir sobre sua situação e reivindicar seus direitos atuando frente a evidente desarticulação do sistema público de saúde do país.
Resolving Donor-Acceptor Interfaces and Charge Carrier Energy Levels of Organic Semiconductors with Polar Side Chains

Organic semiconductors consisting of molecules bearing polar side chains have been proposed as potential candidates to overcome the limitations of organic photovoltaics owing to their enhanced dielectric constant. However, introducing such polar molecules in photovoltaic devices has not yet resulted in higher efficiencies. A microscopic understanding of the impact of polar side chains on electronic and structural properties of organic semiconductors is paramount to rationalize their effect. Here, we investigate the impact of such side chains on bulk heterojunction overall morphology, molecular configurations at donor-acceptor (DA) interfaces, and charge carrier energy levels. The multiscale modeling approach used allows to resolve DA interfaces with atomistic resolution while taking into account the large-scale self-organization process which takes place during the processing of an organic thin film. The polar fullerene-based blends are compared to the well-studied reference system, poly(3-hexyl-thiophene) (P3HT):phenyl-C61-butyric acid methyl ester (PCBM). Introduction of polar side chains on a similar molecular scaffold does not affect molecular orientations at the DA interfaces; such orientations are however found to be affected by processing conditions and polymer molecular weight. Polar side chains, instead, are found to impact considerably the charge carrier energy levels of the organic blend, causing electrostatic-induced broadening of these levels.
