Published: June 2019

AbstractIn the luminous ostracod Cypridina (presently Vargula) hilgendorfii, Cypridina luciferyl sulfate (3‐enol sulfate of Cypridina luciferin) is converted to Cypridina luciferin by a sulfotransferase with 3′‐phosphoadenosine‐5′‐phosphate (PAP) as a sulfate acceptor. The resultant Cypridina luciferin is used for the luciferase–luciferin reaction of Cypridina to emit blue light. The luminescence stimulation with major organic cofactors was examined using the crude extracts of Cypridina specimens, and we found that the addition of coenzyme A (CoA) to the crude extracts significantly stimulated luminescence intensity. Further, the light‐emitting source in the crude extracts stimulated with CoA was identified as Cypridina luciferyl sulfate, and we demonstrated that CoA could act as a sulfate acceptor from Cypridina luciferyl sulfate. In addition, the sulfate group of Cypridina luciferyl sulfate was also transferred to adenosine 5′‐monophosphate (5′‐AMP) and adenosine 3′‐monophosphate (3′‐AMP) by a sulfotransferase. The sulfated products corresponding to CoA, 5′‐AMP and 3′‐AMP were identified using mass spectrometry. This is the first report that CoA can act as a sulfate acceptor in a sulfotransferase reaction.

В статье приводится исследование клеточного и гуморального звеньев иммунитета при респираторной атопии и псевдоатопии в зависимости от уровня поражения респираторного тракта. Изучаемые патологии: атопический риносинусит (АР; n=28), атопическая бронхиальная астма (АБА; n=28), полипозный риносинусит (ПРС; n=68), астматическая триада (АТ; n=28). Группа контроля – здоровые люди (n=219). Гуморальное звено исследовали методом проточной цитофлуориметрии, клеточное звено и циркулирующие иммунные комплексы (ЦИК) – иммуноферментным анализом. Независимо от генеза аллергического воспаления верхних отделов (ПРС и АР), установлено высокое содержание CD19+ клеток относительно бронхиальной астмы, а для бронхиальной астмы (АТ и АБА) – CD8+ лимфоцитов относительно контроля. При псевдоатопии (ПРС и АТ) снижена концентрация sIgA и С1q относительно атопии (АР и АБА). В группе АР увеличено содержание sIgA относительно АБА. Для АТ характерно высокое количество CD3+, CD4+ и низкое содержание CD16+ клеток относительно ПРС.
EFFECT OF SIGMA PHASE PRECIPITATION ON MECHANICAL BEHAVIOR AND PITTING CORROSION OF DUPLEX STAINLESS STEEL
Authors: Berguiga Talha , Boumerzoug Zakaria 
Published: June 2019

<p class="Style1">The main purpose of this work is to investigate the pitting corrosion behavior of sigmatized duplex stainless steel (DSS) exposed to two different chloride environments: simulated seawater solution and produced water solution. Specimens taken from a commercial DSS (UNS 31803) have been subjected to aging treatments at 850°C for different holding times to achieve different amounts of sigma phase. Metallographic examinations combined with X-ray diffraction technique were employed to follow the microstructure evolution. The pitting potential of the aged samples were determined in simulated seawater solution and produced water solution. It was established that solution treated DSS shows a high pitting corrosion resistance in both test solutions, while serious deterioration of corrosion properties occurs in presence of sigma phase. It was concluded that both sigma phase amount and chloride concentration worsen the pitting potential, the higher sigma content, the lower pitting potential and the higher chloride concentration, the lower pitting potential. SEM observation showed that pitting nucleation occurs preferentially at sigma phase interfaces due to the development of Cr- and Mo-depleted regions around sigma phase. It was also confirmed that the hardness behavior is only affected for long term aged samples.</p><p class="Style1"> </p>

<p class="AMSmaintext">We investigated the viscosity of CuPb, CuPbSn, CuPbSnGa and CuPbSnGaBi melts of equiatomic compositions by the method of damped torsion vibrations of a crucible. We see the melts of equiatomic composition as the melts high-entropy. All the investigated melts demonstrated the different temperature dependences of viscosity for heating and cooling. There is an anomalous reduction in viscosity resulted when the melt is heated to a specific temperature. The anomalous behaviour for viscosity we interpreted in terms of melt structure. This structural changes in the melt resulted when the melt is heated to a specific temperature. The microstructure of CuPbSnGaBi ingot of equiatomic composition we investigated using optical microscopy and measurement of microhardness. Collations data of the microstructures with of the microhardness gave three structural components: CuGa<sub>2</sub> dendrites, (Sn) + (Bi) + Bi<sub>3</sub>Pb<sub>7</sub> ternary eutectic and rounded Pb inclusions having dimensions of »5 mm.</p>

A economia criativa e da cultura é configurada pelo plano das ideias e revela suma importância no desenvolvimento de uma região ou país. Assim, orientar e gestar recursos aos setores promotores dessa “nova economia” como os da cultura, por exemplo, gera benefícios a diversos segmentos. O presente trabalho pretende avaliar através da Análise Envoltória de Dados, e suas extensões, dois modelos sobre a eficiência dos gastos com difusão cultural, em reduzir criminalidade e em proporcionar maior nível educacional nos municípios mineiros. Os resultados revelam que, em média, municípios que despendem mais com difusão cultural tendem a apresentar maior eficiência em ambos os casos, reforçando a necessidade de intensificar os investimentos em políticas culturais em consonância com políticas educacionais e de segurança pública.Palavras-chave: Cultura; Políticas públicas; DEA; Criminalidade; Educação; Minas Gerais.

Ownership (Lost) and Corporate Control: An Enterprise Entity Perspective
Authors: Biondi Yuri 
Published: June 2019

AbstractIn recent decades, advocates of the shareholder value perspective regarding corporations have depicted the shareholding investor as the owner of the corporation and the entrepreneur proprietor of corporate activity. Political discourse and regulatory frameworks keep imagining that one single subject or legal person holds the whole bundle of rights and responsibilities related to corporate investment, management and control. This subject would be the shareholding investor (acting as the owner of the corporation), while the bundle would be embodied in the one kind of security issued by the corporation, that is, the share.As a matter of fact, corporate practice shows fundamental disconnection between equity investment, enterprise management and corporate control. Over time, three main legal-economic innovations have featured this disconnection: (i) the very introduction of the corporate legal form; (ii) the working of corporate groups and financial intermediaries; and (iii) the overwhelming web of contractual arrangements and financial derivatives which characterise business affairs of listed companies and equity markets nowadays.In this context, this article argues that an ownership view of corporate activity misleads understanding and undermines efforts to enforce corporate sustainability, responsibility and accountability. Ownership and market are insufficient to assure this enforcement, while ownership sovereignty is irremediably lost. Insisting on such misunderstanding would result in facilitating if not favouring structuring opportunities to circumvent control and responsibility, including through regulatory avoidance.Instead, an enterprise entity view may comprehend the corporate activity (of which the corporation is one possible legal form, often embedded in a more complex legal structure involving an enterprise group) as an organisation and an institution which responds to and must submit to a variety of inside and outside checks and balances, with a view to assuring its consistent and continued role in business and society. From this systemic perspective, consolidated accounting and disclosure may represent a fundamental element of the institutional system of protection. In particular, a comprehensive accounting system – based upon economic substance (rather than legal form) – may make enterprise groups accountable for their ongoing activities to stakeholders (including shareholders), human community and nature.
On the Economic Value of Signals
Authors: Bagh Adib , Kusunose Yoko 
Published: June 2019

AbstractWe provide sufficient conditions for the economic value of a signal to be a convex function, either locally or globally, of the input required to produce the signal. We also provide conditions under which this input can be interpreted as a measure of the information contained in this signal. We demonstrate that, under certain conditions, information is a very peculiar good that can—globally—show increasing marginal utility. In contrast to the earlier approach used to obtain the classic results on the local lack of concavity of the value of information, our approach allows permits the investigation of concavity (or lack) of the function representing the value of information, without imposing any conditions of differentiability on this function. Our approach also allows us to show that the marginal value of information can be zero even at an informative signal. Finally, we discuss some of the difficulties that can arise in designing price discrimination schemes for selling signals with various levels of quality.
Procurement management in construction: study of Czech municipalities
Authors: Hanak Tomas , Korytarova Jana 
Published: June 2019

AbstractEfficient spending of public money is a crucial requirement of public procurement. This requirement is even more important in the case of public works contracts since construction projects are usually very costly. Accordingly, public authorities should manage the procurement process in an efficient way. The aim of this paper is to analyse municipal procurement practices focusing on small-scale public contracts for construction works. The Czech Republic is the study area for this analysis. Data concerning procurement practices were collected through a questionnaire survey and on the basis of available internal municipal directives that govern the procurement process. The results show that a majority of municipalities use internal directives and specify financial categories for small-scale public contracts. It has also been found that the majority of municipalities contract external consulting companies for specific contracts or subsidised public contracts. Directives usually concern the issue of responsibility and the approval procedure related to the public contract. Based on the research findings, general recommendations for awarding public contracts have been formulated. These findings can potentially contribute to the dissemination of best practices among contracting authorities in the Czech Republic.
Generational and Intergenerational Care and Mobility Networks in Kosovo
Authors: Latifi Tahir 
Published: June 2019

Abstract
Generational and intergenerational relations are established according to family patterns, sociocultural, economic, and institutional backgrounds. In the case of Kosovo, where welfare is poor, and economic activity rates are low, kinship ties are very strong. Under these conditions, the state and the market are failing to provide social security to Kosovo’s citizens. In such a situation, solidarity and intergenerational relations play a vital role in keeping families intact and maintaining social cohesion. In this article, however, I point out that strong kinship ties may also have a negative effect—creating a form of distrust of state institutions, and thus weakening the state and the market. Or this could make the state ‘lazy’. The research outlined here is mainly based on data collected during fieldwork conducted in the years 2011-2015 in a village in western Kosovo.
Precarious Retirement for Ageing Albanian (Return) Migrants
Authors: Duci Veronika , Dhembo Elona , Vathi Zana 
Published: June 2019

Abstract
Return migration and pension benefits are crucial for ageing migrants whose migration project takes a significant turn due to circumstances in the receiving country. A significant number of migrants have recently returned to Albania from Greece due to the financial crisis and are struggling to start a new life. A number of those remaining in Greece wish to retire upon return to Albania, or prefer to remain in Greece if they manage to retire there. Problems arise because of the lack of portability of social security benefits from Greece to Albania. This article looks at the policy and legal frameworks of migration and the national social security system, aiming to identify the existing gaps in the policy and legislative configurations of the two countries. It appears that significant policy inconsistencies and gaps have serious implications for ageing returned migrants and also for those remaining in the host country (Greece), indicating an urgent need to address these difficulties at a transnational policy level.
Starting Early with Language Learning. Enhancing Human Capital and Improving the Integration of Migrant Families in the Danube Region. Examples from Bavaria
Authors: Skoglund Ekaterina , Bretthauer Astrid 
Published: June 2019

Abstract
Germany is an important destination for migrants from other European countries. That is particularly true of the Danube region, a European Union (EU) macroregion with deep economic and historical interconnections. Immigrants tend to be younger than the average of the German population, with children accounting for 15% of all migrants. The authors start with a short overview of the theoretical and empirical literature on preschool and early education as a tool for acquisition by immigrant children of the host country’s language. The focus is then shifted to the policy sphere, with the example of Germany and in particular the federal state of Bavaria, in the context of the challenges and best practices used to tackle the integration of such children. The article considers Regensburg, the fourth-largest city in the State of Bavaria, and the Landkreis (district) Kelheim to the southwest of Regensburg as case studies to illustrate the similarities and differences of their municipal approaches to the promotion of German language acquisition by immigrant children and their parents.
Az ösztrogénmetabolizmus várandósság alatt

Published: June 2019

Abstract: The extensive metabolism of estrogen hormones, where oxidized forms, structural isomers and conjugated products appear in many tissues locally as well as in systemic circulation, is believed to be associated with a number of diseases. Targeted estrogen metabolomic studies have been largely associated with postmenopausal, malignant advert immune conditions. Although the role of estriol in maintaining pregnancy and the biological activity of estrogen metabolites is known, a relatively small number of publications have addressed the formation and transformation of these compounds during pregnancy. The aim of this study is to present in detail the formation and progression of estrogen metabolites during pregnancy and to summarize the knowledge of their role in undesirable processes occurring during gestation.

Abstract: Introduction: Airway management is an integral part of general anaesthesia, which may lead to severe short- and long-term complications. Aim: We assessed whether the application of a checklist for the steps of airway management reduces the number of complications in our institute. Method: In our observational, prospective, controlled study we made a checklist and a data collection sheet. Each airway management was performed for one month without the checklist and then for one month in the possession of the checklist. We evaluated the outcome of airway maneuvers and the occurrence of related early complications before and after the introduction of the checklist. The primary endpoint was the incidence of unexpected difficult airway. The secondary endpoints were difficult intubation, successful first intubation, aspiration, cardiac arrest, post-induction hypotension and desaturation, soft tissues/teeth injuries. Our results were also corrected for factors that affect the risk of complications (urgency of interventions, medical experience). Results: We did not find any difference in the frequency of acute complications before the introduction of the checklist (n = 439) and during the subsequent period (n = 423). At the primary endpoint (7.29% and 6.14%), there was no substantive difference (1.15%, 95% CI: –2.26%–4.56%, p = 0.5). No differences were found regarding the secondary and other endpoints. Following the correction of risk factors, there was no impact of the checklist on the incidence of complications. Conclusion: The introduction of the checklist in itself did not result in a significant change in the risk of short-term complications of airway management in our institution.
