Published: October 2021

The involvement of governments and public institutions in entrepreneurial activity has grown considerably in the last years. Public governance has begun to pay more attention to the fact that, in order to achieve the goal of economic development in a country, it is necessary to increase entrepreneurship both qualitatively and quantitatively. Most governments have created significant actions that encouraged and supported the entrepreneurial activity and also they have contributed to supporting the private sector in the economy. The present paper analyses the scientific works related to entrepreneurship and public governance, as well as to investigate the connection between these topics. The study presents a bibliometric analysis of the importance of the nexus public governance and entrepreneurship. The proposed research studies 201 references collected from the Clarivate Analytics, Web of Science Core Collection database. The research methodology performed to graphically map the literature is bibliometric analysis. The analysis is carried out on three distinct levels, namely the analysis of the co-occurrence of keywords, co-citation and co-author by means of (VOS) viewer program. This approach allows us to highlight the main results presented in journals, magazines, documents, subjects, authors, institutions but also results recorded at the country level. The study also evidence the main trends and impact of research in the form of a visual and schematic research framework on the relationship between public governance and entrepreneurship and its related elements, namely innovation and development.

Published: October 2021

The methodology applied for measuring the public sector performance is a disputed topic both in academia and for decision-making policies implementation. Thus, in this paper, we analyze the importance of the topic for researches and also try to identify the methodologies considered within the literature for measuring public sector performance, which would allow comparison between states, and reporting to certain values. The novelty of our approach is that, firstly, we draw a content analysis, with a focus on the methodologies applied for measuring the performance in the public sector in terms of productivity, efficiency, and performance. Secondly, with the support provided by the VOSviewer it is performed a bibliometric analysis and science mapping. We focus our research on keywords co-occurrence, authors co-citation and co-authorship to observe countries and institutions that generate publications on “public sector performance”. On the one hand, our results reveal that entail Analysis of Main Components has proven to be an effective tool to perform complex analysis of public sector performance, through the composite indicator that achieves an aggregation of several important areas of the public sector, considering its complexity and large size. On the other hand, strong links between keywords, researcher’s networks and country and institutions where the research is concentrated where highlighted.

Knowledge, Public Communication and “Post-Truth”: What is Left of Truth in a Time of Pandemic?
Authors: Codoban Aurel , Cordoş Alexandru
Published: October 2021

The pandemic seems to have reversed the relationship between Knowledge and Communication: communication prevails and determines the significance and meaning of events, just as it happened in premodern times. Public knowledge is being eroded. Post-modern scientific knowledge, already unfathomably complex and technical, is both evolving and becoming obsolete at such great speed that it unveils, paradoxically, the vulnerability and relativity of the truth it claims to grasp. Alongside truth-correspondence and truth-coherence, the older truth-significance also makes itself known. Amplified by the resonance chamber of new media and social networks, the latter can emerge as the “post-truth” and “fake-news” that transform Public Communication into Public Relations.

Published: October 2021

The aim of the paper is to identify and describe some specifics of intercultural competence development at the tertiary level in the framework of language and culture. Different views on intercultural competence development in higher education are presented as well as intercultural competence development in different countries and many scholars’ points of views. The results show certain specifics of intercultural competence development including linguistic competence, linguistic and cultural competence, as well as the components of intercultural competence development: the knowledge of foreign languages, cultural background knowledge, and basic soft skills. It is stated that knowing foreign languages, understanding the national culture of the target language, and having universal soft skills are necessary for successful intercultural competence development. Some soft skills are developed too, such as: tolerance, a sense of responsibility for one’s actions, the ability to empathy, understanding and acceptance of a foreign culture, the ability and desire to understand the difference and unity of one’s culture and the country culture of a target language, a sense of adequate and friendly perception of a foreign language and its realities. It is concluded that it is important to know a theory and have a practice for intercultural competence development and intercultural communication, since a foreign language, culture can only be acquired through activities. As for the specifics of intercultural competence development at the tertiary level in national universities, an indirect character of its development and patterning during intercultural communication are characterized.
Historical Evolution of Knowledge: Interpretation of Truth in Postmodernism

Published: October 2021

Changes in society lead to changes in science, changing its fundamental foundations - ideological and value, methodological and instrumental foundations. In turn, a change in the scientific paradigm leads to social change. A situation of this kind is especially evident in the socio-political sciences, since it is they who are more affected by social reality. The nature of postmodern societies is such that its economic component generates a huge number of subcultures, in the scientific world it is called "subcultural explosion." Postmodern societies are societies of permanent changes: consumer standards, moral values, political structure, and so on, repeatedly change during the life of one generation, significantly affect the search for the truth of science and its understanding. In the list of various questions of truth, its character, origin, postmodern departs from objective truth, therefore it becomes contextual and consensus. Theories are replaced by approaches, views, points of view, thoughts. Scientific concepts with their strict certainty change concepts, in which under the same name everyone puts their own meaning and essence. According to this, in postmodernism, not only the scientific paradigm as a model of scientific activity is changing, but the purpose of science, its understanding as a special activity with the search for truth, is changing. This implies a review of the attitude to the "organizational forms" of science, that is, the way in which scientific knowledge is disseminated to the professional scientific community to search for truth, which in its classical understanding no longer exists.
Contextualization of the Classic Moral Sentimentalism
Authors: Mihail Rarita
Published: October 2021

Moral sentimentalism can be defined as the philosophical theory according to which emotions are the source of our value judgements, in general, and of our moral judgements, in particular. It follows that, from a historical and conceptual point of view, moral sentimentalism has emerged and developed in opposition to moral rationalism, according to which reason allows us to formulate and understand value judgments from a psychological point of view and is also the source of our axiological knowledge from an epistemic point of view. In this article we present the theoretical issues related to the sentimentalist approach to morality and evaluative judgments, starting from the diverse theories of the classical representatives of sentimentalism, Shaftesbury, Hutcheson, Hume and Smith, and especially the three theses they defended: psychological perspective, the theory of moral sense and the theory of moral feelings. I also argue that the first moral sentimentalism emerged from the confrontation of three distinct aporia: the first aporia refers to the conceptualization of emotions and emotional states; the second deals with the possibility of axiological knowledge; and the third refers to the nature and existence of values. Finally, we are interested in the birth of sentimentalism in order to highlight a series of difficulties inherent in this theoretical approach and which we find today in contemporary moral sentimentalism. The aim is to highlight the conceptual and argumentative tensions that were at the heart of sentimentalism at its emergence.
Artistic Aspects of Embodiment of Postmodern Theater Practices in the Context of COVID-19 Pandemic

Published: October 2021

At the turn of the 20th and 21st centuries. When integrated into the European art space, the countries of Eastern Europe take the path of creating a new model of cultural development in a post-pandemic society. Added to the world of theater innovations and, in particular, post-modern theater practices, it makes it necessary to search for new types of communication with the audience, creating such a balance between the actor and the audience that would meet new historical realities, shape its cultural landmarks, moral values, and provide meaning for current events. Consequently, the new historical realities require theatrical culture to change the artistic trajectories of development and at the same time determine the cultural reflection on its place and role. In culturological and art studies, the theater, as a rule, is considered as a system component of the cultural space. This corresponds to the generally accepted approach: the definition of culture as a set of spheres, each of which has its own specifics. These areas are combined by certain socially significant factors (worldview, way of being, set of values), according to which they must coordinate their way of existence. Now, in a post-pandemic society, there is not enough research that examines the latest formations at the place of origin and is perceived as the products of the local experience of the individual and the society to which he belongs.

Published: October 2021

The modern world space, which is affected by the post-pandemic consequences, is noted by the globalization of society, the increasing role of citizenship in making important state and international decisions has become possible in the context of the information revolution and has its own characteristics of communication in information and communication networks. The importance and need for a thorough study of the chosen topic is that the widespread use of various forms and methods of civil communication, free access of citizens to information at all stages of decision-making and the functioning of central and local governments, the participation of civil society institutions in the work of expert, consultative, and advisory public councils on the expression and protection of the rights and freedoms of citizens, public control, direct electronic receipt of public services, etc. are important factors in the democratization of government in post-pandemic modern times. After all, we are talking about a deliberate orientation to new values - the person and the collective, their direct participation in the democratic organization of life of the state and society. The main thing in this context is that the rational consensus of civil society and the state is a factor in universal social discourse and a strategic resource for democratic development in the context of post-pandemic modernity. The aim of the article is to consider the epistemological and sociocultural aspects of the functioning of the communication capabilities of civil society institutions in the context of revealing the possibility and significance of their involvement in the processes of implementing state security policy.
Physicians Professional Immunity in the COVID-19 Pandemic. Problems and Solutions
Authors: Rotila Viorel
Published: October 2021

In this article, by professional immunity we refer to limitation of liability to the specific pandemic context, respectively to the concrete possibilities of diagnosis, treatment, care and too few degrees of professional freedom still available. The relevance of one or another of the limitation measures of professional liability depends on the specific legal context of each community. Our thesis is that, regardless of the form of transposition into practice, a form of health professionals protection, such as professional immunity is necessary. From the multitude of possible protection measures, each state can select the appropriate ones. The need for specific measures for professional immunity is not identical in each state, depending on the specifics of the legal system, social values, measures characteristics taken to combat the pandemic, the degree of transparency of each healthcare system, the level of bioethical principles influence. However, this need doesn`t start from "no measure", the appropriate minimum level of protection seemingly to constitute a patient compensation no-fault model, plus the characteristics of the professional immunity, designed to adapt liability to specific conditions.  The main problem in the absence of professional immunity is the risk of transferring the cost of ignorance, visible, in the inadequate expectations of medical science, on healthcare professionals, the limits of scientific knowledge risking to be reinterpreted as medical fault. The COVID-19 pandemic has somehow forced an additional step towards broadening discussions on universal human rights, being forced to consider ways of putting them into practice in the context of limited resources. Assuming that the increase in social complexity increases the risks of such events, we approach these problems from the perspective of creating rapid mechanisms to adapt to such changes, the lessons learned now being applied in the future to other similar cases.

Authors: de Almeida Odenir , Catalano Fernando M. , Pereira Lourenco Tercio
Published: October 2021

For achieving accurate aeroacoustic measurements to the aircraft industry, a low-speed wind tunnel, primarily designed for aerodynamic testing, is modified to provide lower background noise environment. Based on data from single microphone at different wind tunnel locations and microphone phased-array measurements inside the test-section, the main noise sources are identified and feasible alternatives are implemented for reducing the background noise such as new acoustically treated corner-vanes and sidewall lining located upstream the drive system. The acoustically transparent concept for the test-section is also investigated showing promising results for further improvements in the wind tunnel. Results are presented for sound pressure levels from single microphone measurements at different locations in the wind tunnel as well as from the beamforming array inside the test-section. Background noise measurements before and after improvements confirm that the ability of performing aeroacoustic tests has significantly increased with noise reduction of 5 dB inside the test-section.

Published: October 2021

The use of fossil fuels by anthropogenic activities causes ocean acidification and warming, and the combined conditions of these two environments can negatively affect fish metabolism, growth, and survival. Additionally, it can affect the antioxidant enzyme activity and cell damage caused by lipid peroxidation. In this study, we explores the adaptive potential for future marine conditions by investigating the stress and antioxidant enzyme activity, and apoptosis of juvenile olive flounder in an environment where ocean acidification and warming coexist. We found that juvenile olive flounder had increased oxidative stress and apoptosis under both warming and combined warming, and acidification conditions. Additionally, the effect on acidification under warming conditions does not seem to exceed the effect of high temperature conditions, and it is considered that the effect of acidification at low water temperatures is greater.

Published: October 2021

Coal-series kaolin is an associated mineral resource in coal mining process, often contains organic components and other discoloring impurities, which may lower the quality and limit the industrial application. However, the occurrence, stability of organic component and how they affect the surface physical and chemical properties of coal-series kaolin is known little. In this article, several representative organic components have been enrolled for analyzing the interactions with different minerals of the coal-series kaolin. Results shows that the unsaturated double bonds may be easier to adsorb with kaolinite, and the energy on C20H40 is the least among all the compositions. Among the different crystal planes of kaolinite, the (001) surface may possess higher adsorption characteristic on the organic molecules, which may be consistent with the crystal face index of the kaolinite. While the adsorption energy between the organic molecules and the impurities in coal-series kaolin was positive all the time, suggesting that the organic matter could only adsorb with kaolinite compared with the impurities such as pyrite, quartz and anatase. Calculations of state density also showed that the displacement of the energy band for kaolinite may shift to the lower state after adsorbed with different organic matter, also a rearrangement and significant increase of peak values for the state density may occur after adsorption. This study aims to provide a theoretical basis for the occurrence state and stability differences of different organic matters on the coal-series kaolin, also further solve the long-term problems of restricting the whiteness and comprehensive utilization of coal-series kaolin resources.

Neural Network Modeling of NiTiHf Shape Memory Alloy Transformation Temperatures
Authors: Abedi Hossein , Qattawi Ala
Published: October 2021

Machine Learning (ML) techniques enabled the effective correlation of alloy characteristics. In this paper, an ML Neural Network (NN) model is proposed to predict the transformation temperatures (TTs) of NiTiHf for a given combination of elemental composition and processing parameters within an acceptable confidence interval. The main challenge in NiTiHf TTs prediction is the high dimensional dependency of TTs to various parameters as well as not fully clear governing physics. Considerable experimental research was performed from 1995 to design the NiTiHf TTs which in turn paved the path to feed the ML algorithms which are now presenting an excellent approach for material design. A thorough data set is constructed from both unpublished data and available literature and then analyzed to select twenty input parameters to feed the NN model. To model and forecast the TTs of NiTiHf with a wide range of TTs up to 800°C, a total of 173 data points are gathered, verified, and selected. The model's overall determination factor (R2 )was 0.92, indicating the viability of the proposed NN model in showing the link between material composition, processing factors, and then defining the TTs of NiTiHf alloy. The effort additionally validates the generated results against existing data in the literature. The validation confirms the significance of the proposed model.

Diclofenac degradation based on shape-controlled cuprous oxide nanoparticles prepared by using ionic liquid
Authors: Huang Jialei , Luo Yan
Published: October 2021

Persulfate oxidation technology is widely used in wastewater treatment, but there are still many disadvantages, such as high energy consumption, side reaction and narrow pH applicability. Copper oxides can activate persulfate steadily with higher efficiency. In this paper, a novel preparation method of shape-controlled cuprous oxide (Cu2O) nanoparticles featured with high catalytic performance was explored. It was found that adding ionic liquid 1-butyl-3-methylimidazolium bromide ([BMIM]Br) during preparation of Cu2O can improve the degradation rate of diclofenac (DCF). Cu2O nanoparticles possess good stability in consecutive cycling tests, which was confirmed by X-ray photoelectron spectroscopy. The possible mechanism of Cu2O activating persulfate at different initial pH conditions was discussed based on electron paramagnetic resonance spin-trapping experiment. It was found that DCF was efficiently degraded in the Cu2O/peroxydisulfate (PDS) system within a broad pH range from 5 to 11. It proved via a quenching experiment that the activation process of PDS mainly occurs on the surface layer of Cu2O nanoparticles. As a result, shape-controlled Cu2O nanoparticles prepared by ionic liquid are expected to be used for in situ chemical oxidation, which is an effective oxidation processes to degrade DCF remaining in surface water and ground water.
Education, APOE ε4, and Cognition in Individuals with Subjective Cognitive Decline with Worry in the SILCODE Study
Authors: Chen Guanqun , Lin Li , Yang Kun , Han Ying
Published: October 2021

Background:

Education could offer a protective effect on cognition in individuals with
Subjective Cognitive Decline (SCD), which is considered to be the early stage of Alzheimer’s Disease
(AD). However, the effect of education on cognition in SCD individuals with SCD-plus features
is not clear.

Objective:

The aim of the study was to explore the effect of education on cognition in SCD individ-
uals with SCD-plus features.

Methods:

A total of 234 individuals with SCD were included from the Sino Longitudinal Study on
Cognitive Decline (SILCODE). Cognition was assessed across 4 domains (memory, executive, language,
and general cognitive functions). Multiple linear regression models were constructed to examine
the effect of education on cognitive scores in individuals without worry (n=91) and with worry
(n=143). Furthermore, we assessed differences in effects between APOE ε4 noncarriers and
APOE ε4 carriers in both groups.

Results :

Multiple linear regression analysis showed a positive effect of education on memory, executive,
and language cognition in individuals without worry and all cognitive domains in individuals
with worry. Furthermore, we found a positive effect of education on executive cognition in
APOE ε4 noncarriers without worry and language and general cognition in APOE ε4 carriers without

NiO nanoparticles are utilized to effectively strengthen annulated pyrano [2,3-d]
pyrimidine synthesis through primary Knoevenagel, following Micheal and ultimate heterocyclization
reactions of aldehyde, malononitrile, and barbituric acid. The characteristics of NiO
nanoparticles are identified using advanced techniques, such as IR, UV, EDX, XRD, SEM, and
TEM. The nano-NiO particles are mostly below < 100 nm in size with uniform spherical shapes.
The adopted approach is advantages owing to its simple processing, relatively short reaction time,
often good to high average yields, convenient workability, and environmental friendliness.

:

Coumarin is a privileged scaffold that contains the unique 2H-chromen-2-one motif, and its
derivatives are widely distributed in nature, especially in plants. In recent years, due to their diverse
pharmacological activities and remarkable photochemical properties, they have attracted significant
attention from scientists, which has also prompted the research on the synthesis approaches and the
availability of substrates for these compounds. This article is a brief description of the methods for the
synthesis of various coumarin derivatives via two- or multi-component reactions involving 3-amino
or 4-aminocoumarin reported during 2015-2021. This review may help expand the development of
various analogues with coumarin as the basic unit.

This review described the preparation of 2- chloroquinoline-3-carbaldehyde derivatives 18
through Vilsmeier-Haack formylation of N-arylacetamides and the use of them as a key intermediate
for the preparation of 2-(piperazin-1-yl) quinoline-3-carbaldehydes. The synthesis of the 2-
(piperazin-1-yl) quinolines derivatives was explained through the following chemical reactions:
acylation, sulfonylation, Claisen-Schmidt condensation, 1, 3-dipolar cycloaddition, one-pot
multicomponent reactions (MCRs), reductive amination, Grignard reaction and Kabachnik-Field’s
reaction.
Nanoparticle Production of Zingiber officinale Roscoe Rhizome Extracts
by ESS (Expansion of Supercritical Solution)
Authors: Raofie Farhad , Rezvanjoo Zahra
Published: October 2021

Aims:

To propose a modified RESS method of herbal pharmaceutical extracts nanoparticle
production.

Background:

A vast number of methods have been applied to water-insoluble pharmaceuticals to improve their solubility. Nanoparticle production of pharmaceuticals is considered as one of the high-speed
ways to improve solubility.

Objective:

Supercritical CO2 was applied to extract Zingiber officinale Roscoe rhizome pharmaceutical.
Then, a modified RESS (Rapid Expansion of Supercritical Solution) method, called ESS (Expansion of
Supercritical Solution), was exerted to obtain NPs (nanoparticles) of the extracted pharmaceuticals.

Methods:

Initially, applying high pressure in supercritical CO2 contributed to the extract dissolution such
that supercritical CO2 was saturated with the sample. Then, by decreasing the pressure, an expansion occurred in the saturated medium. This expansion reduced the power of supercritical CO2 solvent and induced the sample nanoparticle nucleation in the needle valve.

Results:

LC-MS (Liquid Chromatography-Mass Spectrometry) and EDX (energy dispersive X-ray spectroscopy) result provided solid evidence for the presence of anti-cancer pharmaceutical, [6]-Gingerol, in
the extract. The medium size of the nanoparticles in FESEM (Field Emission Scanning Electron Microscopy) analysis was 36 nm. The most satisfactory parameters for a 2 mg mL-1 feeding solution were the
initial pressure of 350 atm, secondary pressure of 160 atm, equilibrating time of 10 min, precipitating
time of 20 min, and temperature of 48 °C.

Conclusion:

Unlike rapid expansion of supercritical solution methodology, in this technique, the initial
and secondary pressures were permanently above the critical pressure to provide a gentle expansion,
which contributes to the production of uniform and small particles. The obtained uniform NPs had a narrow size distribution. Consequently, ESS technique can be considered as an efficient technique for improving the solubility of hydrophobic pharmaceuticals, such as [6]-gingerol.
Bibliometric Analysis of the Research on Photo-electrocatalysis and Its
Possible Application to Wastewater Treatment
Authors: Palmas Simonetta , Vacca Annalisa , Mascia Michele , Mais Laura
Published: October 2021

Background:

Possible applications of photoelectrocatalysis in the field of environmentally
sustainable processes have inspired an exponentially increasing number of papers in the last decades.
Less frequently, bibliometric analyses are presented, which are especially useful when a considerable
amount of data is involved: metadata can be viewed from micro to macro perspective and may suggest
ideas for future research.

Objective:

The objective of this study is to derive information on the research trends and to individuate
possible gaps in specific topics, as well information on the authors and their related countries and
institutes, and to quantify possible cooperation patterns between them.

Methods:

In addition to the classic data analyses immediately available on the database, such as the
trend of the number of publications per year and the list of the most active authors or countries, the
bibliometric analysis has been carried out using the VOSviewer software. Co-authorship and cocitation
analyses have been performed, as well as co-occurrence of the keywords explicitly indicated
by the authors.

Conclusion:

Based on the publications in the SCOPUS database, the present work analysed the
metadata relating to scientific articles published in the last two decades, dedicated to the research on
photo-electrocatalytic processes and their possible application on wastewater treatment. Based on the
list of the references present in the examined papers, the co-authorship analysis and the co-citation
analysis also allowed the identification of the authors and the publications which have been most influential
on the research on the examined topics. Indication has been obtained on the trend of the main
topics investigated in time, as well as the current gaps in terms of content-wise and geographic cooperation.
