Blaga-Cioran: Incursiuni În Marginea Fiinţei
Authors: Gogoșeanu Mihaela-Oana
Published: February 2022

The following paper focuses on what lies between transcendence and reality, between self and non-self, between bounded and infinite, it focuses on that included third which contradicts Aristotelian logic and which is represented by the margin itself, by the boundary between these concepts, as it is reflected in the texts of Lucian Blaga and Emil Cioran. The role of the limit is analysed especially in those contexts in which, in addition to spatial references, the limit has a figurative meaning, that of term at the intersection of an antithetical binomial that advances the being, in Hegel’s vision, towards becoming. Consequently, the paper will refer to texts from Blaga’s poetry, where there are twenty occurrences of the word “limit” (Romanian: “margine”), six of which meet the semantic condition mentioned above, but also in Cioran’s texts that treat this matter.
Jertfa Pentru Creaţie: Mitul Estetic La Lucian Blaga Și Henrik Ibsen (Studiu De Caz: Dramaturgia Românească Vs. Dramaturgia Scandinavă)
Authors: Hodârnău Ioana
Published: February 2022

This paper tackles the myth of creation through sacrifice as depicted in Lucian Blaga’s theatrical piece “The master builder Manole” („Meșterul Manole”, 1927) and Henrik Ibsen’s “The Master Builder” („Constructorul Solness”, 1892). The purpose of this paper is, therefore, to explore the ways in which this myth passes through different european cultures. The symbols which gravitates around these literary works become premises for a paradigmatic, psychoanalytic and anthropological analysis.
Mihail Sebastian - Rasism, Renegare Și Huliganism
Authors: Ticărău Iulia-Maria
Published: February 2022

The accusations and controversies arising from the appearance of the novel For Two Thousand Years.. are numerous. Some of the most radical are accusations of anti-Semitism and repudiation of Sebastian’s own Jewish ancestry. Through How I Became a Hooligan, Mihail Sebastian responds to these accusations by emphasizing that Jewishness is presented in the novel from a metaphysical perspective, leaving aside politics and everything that politics implies.
Condiţiile Și Strategiile Unui Transfer De Capital Cultural: Importul Poeziei Americane În Optzecismul Românesc
Authors: Farmatu Teona
Published: February 2022

Within the frame of theoretical ideas of World Literature methodology, my paper is aiming to reconsider the relationship between the post-war North-American poetry and the Romanian 80s Generation of poets. Being a complex import, this article sheds light on the conditions and the strategies of this phenomenon through a contextual equation which is more important than a strictly textual one. As a major conclusion of this research, the import of North-American poetry forms, models, ideas, as well as of ideological attitudes is the result of the Romanian young authors’ emulation regarding this faraway literary model. Therefore, this relationship between a centre and a (semi)periphery does not imply a colonizing model of a major culture’s hegemony on a minor one.
Transparenţa Ca Postumanism: O Restaurare A Omului În Literatură
Authors: Partenie Bianca Maria
Published: February 2022

The present study aims to encapsulate the emergence of the posthumanism (and of the posthuman, implicitly), seen as profoundly human, in Radu Vancu’s Transparenţa. The starting point for selecting the characteristics of such a posthumanism peculiar to Radu Vancu is represented by his literary study Elegie pentru uman: o critică a modernităţii poetice de la Pound la Cărtărescu. From his analysis upon the antihuman side of modernity’s project, I extract the four typologies through which literature has fought against (the social, political and artistic) dehumanization: corporeal, confessional, maximalist and sacred. Following at the same time Elegie pentru uman and Transparenţa I reach the conclusion that Radu Vancu uses in his novel all the aforementioned typologies in his project to restore the human. In other words, Elegie pentru uman, in its first part, is, in a way, an ars poetica, a drawing in nuce of the forthcoming novel. To this group of four typologies enlisted by Radu Vancu, I will add one more, peculiar to his writing, which emerges from the study as well as from the novel: poeticality.

The fifth category looms in the novel’s writing and in the reference to Ion Mureșan within Elegie pentru uman. Ion Mureșan described literature as the immune system, while the poets are seen as the antibodies of society. Thus, the poeticality within the novel is an immune system which helps the restoration of the human, becoming a key element of the posthuman fiction in Radu Vancu’s text.

The second part of the study will focus on the close reading of the function of some fictional objects in the posthuman narrative of Transparenţa. The selected fictional objects are the ones which are vital for the human salvation from the dehumanizing ghosts of recent history. Such fictional objects are: the body, the light, the text, the reader, Mega, Sibiu etc. Seen through the filter of a posthumanism deeply human at its core, the novel presents the story of a narrator who whishes to restore his lover and, implicitly, the whole world. To conclude in Dostoyevskian terms: humanity will save the world.

Authors: Bach Mirjana Pejić , Omazić Mislav Ante , Miloloža Ivan
Published: February 2022

The experience of many organizations so far has shown that the risk of failure of the software implementation project is high, and in order to reduce this risk, significant efforts have been made so far to implement the project management methodology. However, research to date shows that, despite improvements in project management, a relatively significant number of projects still fail by some of the performance criteria. A methodology is proposed that includes: (i) analysis of previous research; (ii) design a research instrument to measure project performance and define key determinants of project performance; (iii) development of a multi-criteria model for measuring the performance of software projects; (iv) development of software project management performance models for Croatian organizations using a data mining approach. These activities can be carried out using the following methods: bibliographic analysis of previous research, survey research method, descriptive and inferential statistics methods, structural equations method and data mining methods (supervised and unsupervised learning, text mining). The results of this research framework can be used as a starting point for researching the success of business software implementation projects.
The first year of covid-19 in croatia - a mathematical model
Authors: Rodiger Tibor , Glavaš Edgar , Kovač Ivan
Published: February 2022

The new coronavirus has spread around the world at an unprecedented speed. Understanding patterns of disease spread is an important contribution to controlling any epidemic, and today’s mathematical methods offer a plethora of proven models to choose from. We provide a brief overview of epidemiological concepts, papers pertaining to mathematical modelling, and present a robust, simple mathematical model to model incidence of COVID-19 cases in Croatia during the first year of the disease. For our models, we chose logistic, Gumbel and Richards functions, with parameters generated using the Levenberg-Marquardt iterative method of nonlinear regression. In conclusion, all three models provided adequate estimation of incidence curve and final number of infected during the chosen time period, with relatively minor differences depending on chosen parameters of significance. The model using the logistic function proved to be the most applicable to available data. While no model can give the answers to ending the pandemic, this approach can provide a simple prognostic tool to evaluate interventions and estimate disease spread.

Published: February 2022

The National Department of Public Works and Infrastructure (NDPWI), an agency for infrastructure development in South Africa, provides accommodation and other infrastructure to various public service departments. Each department communicates its infrastructure requirements with the NDPWI. However, there are usually time lags between project briefing and the actual delivery of the infrastructure. Therefore, this article aims to explore the causes of delays and offer solutions to enhance customer satisfaction. The case study method of qualitative research was adopted. Data were collected from the NDPWI regional offices in Bloemfontein, Cape Town and Kimberley, and the professional service department at the head office in Pretoria, among purposively selected participants not below the deputy director level. The Delphi technique was used as an instrument for data collection and complemented during a focus group session. The findings revealed that the major factors contributing to delays included poor planning by the project execution team (PET), ineffective project monitoring and overcentralisation of the decision-making process. The findings, conclusions and recommendations of this research provide useful information for organisational restructuring, the training and continuous retraining of project personnel, especially the project managers. These steps hold the potential for ameliorating the negative effects of delay in the execution of construction projects by the NDPWI.

Applying blended foresight methods for revealing incentives and future strategies of key national innovation system players
Authors: Chulok Alexander
Published: February 2022

The paper aims to develop and apply a methodological approach that could help to reveal incentives and future strategies of key National Innovation System (NIS) players considering the influence of global social, economic, scientific, technological and ecological trends. To fulfil this aim, a blended foresight methodology was applied, grounded on the platform of economic and classic foresight theory and considering four possible directions for using foresight methods: investigating and building a common vision; supporting evidence-based decisions; promoting communication and participation; inducing transformation and integration into the decision-making process. The main results and findings of the research include a list of 19 global trends, defined from literature analysis and the author’s expert knowledge, a short description of their influence on key NIS players, including society, business, infrastructure and institutions, science, education and government; and mapping more than 35 different foresight methods that could be used for revealing incentives and future strategies of key NIS players. The article’s theoretical contribution to economic theory consists of several parts. First, a NIS conception is examined through the prism of global trends and a dynamic aspect, whereas it is mostly investigated from statistical and static perspectives. Second, applying foresight as an instrument for researching NIS as a system is a developing academic area with some theoretical gaps, considered in this article by designing a conceptional research framework. Third, blending different foresight methods is always a craft, and the approach applied in this article contributes to it. Finally, the article presents several important trends which will appear in NIS and its key players’ transformation in the nearest 5–10 years. From practical implications, this article could be useful for proactive policymakers in the field of science, technology and innovation policy at national and regional levels for designing and providing measures for supporting innovation systems effectively. Foresight practitioners and experts are offered useful, practical ideas of different foresight methods and their possible combinations for everyday activities.
Clinicopathological characteristics in women with breast cancer in extreme ages in Greece: A single centre experience
Authors: Karachalios Charalampos , Karamitrousis Evangelos , Daskalakis Panagiotis
Published: February 2022

Introduction

Breast cancer is the most common malignancy in Greek women. The highest incidence occurs in patients aged 40–70 years. However, the emergence of the disease in women under 40 and over 80 years old is a significant problem in everyday practice, because of the diagnostic and therapeutic challenges for these age groups. The objective of this study is to investigate clinicopathological characteristics of Greek women under 40 and over 80 diagnosed with breast cancer during 2019–2020 in a specialized Breast Cancer Surgical Centre, as well as the pathological characteristics of their disease and the therapeutic measures applied to these women.

Aim of the study

The aim of this study is to compare clinical and pathological characteristics of breast cancer in a group of Greek premenopausal women younger than 40 years of age with a group of elderly women older than 80 years old, who were treated in a surgical breast centre in Greece during the last two years.

Patients and Methods

During the last 2 years, 21 women under 40 and 22 women older than 80 were diagnosed with breast cancer in our Centre.

Results

Invasive ductal adenocarcinoma was the most frequent histological type for both Groups: Most younger women underwent surgery followed by chemotherapy, while the majority of older patients received hormonal therapy after surgery.

Conclusions

There were no statistically significant differences between women under 40 and women over 80 in the study sample regarding their clinicopathological characteristics. However, younger women underwent more therapeutic modalities (i.e.adjuvant treatments in addition to surgery) than older ones.
Assisted migration vs. close-to-nature forestry: what are the prospects for tree populations under climate change?
Authors: Gömöry Dušan , Krajmerová Diana , Hrivnák Matúš , Longauer Roman
Published: February 2022

Climate change is currently perceived as the most important challenge faced globally by ecosystems and human society. The predicted changes of temperature and precipitation patterns are expected to alter the environmental conditions to which forest trees in Europe are adapted, and expose them to new pests and pathogens. This would unavoidably lead to a huge loss of ecosystem services provided to society, and at the local scale may potentially endanger the very existence of forests. In this study, we reviewed biological background and limits of mechanisms by which tree populations may cope with climate change: adaptation by natural selection, gene flow, epigenetic phenomena and phenotypic plasticity, as well as forest management strategies, which rely on these mechanisms. We argue that maintaining genetic diversity is important in the long-term view but natural selection cannot ensure sufficiently rapid response to environmental change. On the other hand, epigenetic memory effects may change adaptively relevant traits within a single generation, while close-to-nature forestry practices are the basic requirement to make use of epigenetics. Assisted migration, as a frequently suggested mitigation option, relies primarily on the knowledge gained from provenance research; the review analyses potential pitfalls of this strategy. We suggest that all approaches, i.e., leaving a part of forests without management, close-to-nature forestry, and transfer of forest reproductive materials from sources presumably adapted to future climates are combined across the landscape in an integrative manner.
Meaning equivalence issue of English and Lithuanian terms of finance
Authors: Stankevičienė Virginija , Šestakova Viorika , Zavistanavičienė Daiva
Published: February 2022

The intensification of language contacts has led to increasing problems of compliance between terms in different languages in the translation of subject-specific texts. Dictionaries are the main tool in clarifying term meanings and trying to find the most appropriate version which could be perceived by the representatives of different languages equally. More accurate dissemination and usage of the term equivalent allows the addressee (recipient) to better comprehend the contents of the language. Not only are meaning explanation and consistency of definition formulation significant aspects in compiling bilingual dictionaries but also determination of term equivalents. Although terms of economics have old traditions in various languages, it is possible to notice the cases of meaning discrepancy and different perception. The choice and usage of appropriate term remain crucial in communicating about various finance-related operations. The more accurate and clearer the term the better perception of the subtleties of other language. The purpose of this article is to determine the extent to which the concepts of a semantic group representing finance are equivalent, i. e. how similar and different their features are in English and Lithuanian. The research revealed that the majority of the analysed terms are partially equivalent in both languages. Hence, partial equivalents and surrogates in particular may cause confusion and discrepancy in term meaning perception.
Didactic and pedagogical dimensions of Igbo oral children’s songs
Authors: Nwosu Onyebuchi , Ibezim Obinna , Ugochukwu Ngozi G.
Published: February 2022

There is a sharp decline in the performance of Igbo oral songs by children in recent times. Unlike in the days gone, children of nowadays rarely gather in groups in the evenings or during moonlight nights to play and perform some dramatic and musical renditions which are informal forms of education. Parents now encourage their children to watch home-movies and some channel programmes in the comfort of their homes; they encourage them to embark more on some in-door games while advancing security reasons as the basis for not allowing them to participate in various forms of open communal recreation. Such attitude deprives children of the essential moralistic and educational values expected to be imbibed from the rendition of native songs in playful groups. This paper which is based on a fieldwork carried out in 2018 in Umuawuchi, an Igbo community in Imo State Nigeria, investigates the instructional values of Igbo oral children’s songs. Reiterating the moral-imparting attributes of Igbo children’s songs, the paper applies Performance Theory to investigate the thematic standpoints of Igbo children’s songs while gauging the extent to which they can be applied to impart and extrapolate on key moral values of the Igbo. The paper restates certain measures that can be activated to incorporate children’s songs into mainstream educational and mass-communication media to avert the complete loss of such rich literary repertoires.
The Relation Between Photoconductivity Threshold and Open-Circuit Voltage in Organic Solar Cells
Authors: Grzibovskis R. , Ruduss A. , Polaks A.
Published: February 2022

Most of the solar cell parameters (short-circuit current, fill factor, power conversion efficiency) can only be determined by creating and measuring the solar cell. However, there is an empirical relation that links energy level values of the materials in the active layer to an open-circuit voltage (Uoc) of the solar cell. Due to a variety of possible methods used to determine energy level values and the dispersion of obtained results, this estimate is not always correct. Even if correct energy level values are obtained for separate materials, energy level shift takes place at the interfaces when two materials are mixed. That is why a simple and reliable experimental method for Uoc estimation is required. Usually, photoconductivity is used to obtain the energy gap between molecule ionization energy and electron affinity of a single material. When two materials are mixed, direct charge transfer from donor to acceptor molecule can be observed. The threshold energy (ECT) shows the real difference between donor molecule ionization energy and acceptor molecule electron affinity. This difference should correspond to the Uoc. The present study makes the comparison between the open-circuit voltage estimated from material energy level values, the obtained ECT values for various donor:acceptor systems, and the real Uoc obtained from solar cell measurements. Strong correlation between ECT and Uoc is obtained and the photoconductivity measurements can be used in the estimation of Uoc.

Changes in nanostructure morphology and size may result in very different surface wettability. In this research, the impact of different morphological parameters on the wetting dynamics of ZnO nanostructured layers is studied. Six different morphologies are chosen to determine the specific wetting processes of ZnO nanostructures: nanoneedles, small diameter rods, large diameter rods, nanotubes, nanoplates, and plain thin films. Wetting dynamics is investigated using conventional sessile drop technique and a novel approach based on electrochemical impedance spectroscopy. The results show that the surface of nanostructured ZnO thin films exhibits both hydrophilic and hydrophobic wetting behaviour, depending on nanostructure form, size, and orientation. ZnO nanostructure arrays are a promising platform for electrochemical and optical sensing in aqueous solutions. The full and effective use of the sensor working surface can be ensured only under the condition of complete wetting of the nanostructured layer. Therefore, it is important to take into account the peculiarities of the wetting process of a specific morphology of nanostructures.

A Survey on Polish Consumers’ Perceptions of Meat Produced from Stem Cells in Vitro
Authors: Popek Stanislaw , Pachołek Bogdan
Published: February 2022

Despite the dynamic development of technology related to the production of artificial meat, this product faces one more important challenge in terms of gaining consumer acceptance. In the literature on the subject, limited research has been done on the perception of meat in vitro across different societies; therefore, there is little knowledge of the possibility of its acceptance and the type of barriers it may encounter. The aim of this study was to assess the perception of meat produced from stem cells in vitro by Polish consumers. The study was voluntary and was conducted based on an internet survey addressed to people aged 12 to 60+. Convenience sampling of respondents was used. The research sample consisted of 424 respondents with a diversified sociodemographic profile. The results showed a diversified interest in meat produced from stem cells in vitro among Polish consumers. Many respondents were not able to clearly define their preferences for this type of product. Young people showed the greatest positive interest in innovative in vitro meat. The greatest concerns of consumers were related to the lack of knowledge about this type of food, the lack of its inherent naturalness and potential negative health effects.
Knowledge and Entrepreneurial Skills in the Startup Ecosystem — The Case of Georgia
Authors: Shonia Devi , Trzmielak Dariusz M. , Abramidze Tamar
Published: February 2022

Georgia, despite the country’s specific and complex geostrategic position, continually tense political environment, diverse views on economic development among its society and many other issues, nevertheless resolutely strives towards an overarching national idea: liberation from Russian occupation, unification of the country, formation of a knowledge economy and European integration. Crucial for this idea is economic development, which in turn hinges in part on innovation. The pace and scale of innovation are shaped primarily by scientific research and entrepreneurial achievements. Robust economic development therefore requires universities to increase entrepreneurship and initiate change in the areas of science, technology development, and new technology startup support in economic and social terms. In this article, we examine the strong relationship between the development of an appropriate ecosystem for start-ups and support for the process of new business formation in Georgia. Academic centers form one of the essential components of the ecosystem for start-ups in Georgia; their development guarantees access to knowledge and the ability to manage entrepreneurship, and the development of new companies, including innovative ones.
Transient response of “Brezina concrete arch dam”–“Reservoir water”–“Rock foundation” system

Published: February 2022

In this paper, transient responses of the Brezina concrete arch dam, located in the west of Algeria, are determined using the finite elements commercial package, Ansys. A 3D model has been created to study the rock–fluid–structure interaction phenomenon. The foundation rock is modeled as a mass rock using solid finite elements, and the reservoir water is modeled using fluid finite element for the 3D model; the length and width of the foundation rock and water reservoir, along the global X and Y axes, are taken to be 150 m and 300 m, respectively, while its depth (or height), along the Z direction, is taken to be 100 m (the total height of the model is thus 160 m considering that the reservoir water height is taken to be 50 m). Coupling equations available in the Ansys code library are used to represent the dam–water and dam–foundation interfaces. It is found that the role of the reservoir water is mixed. In some cases, its presence is like a damper, which means it decreases the range of displacement or stresses, whereas in other cases, it increases or has a negligible effect on these quantities. A notable finding is the magnitude of the calculated stresses, which stands at a very low level, either with or without water. An in-depth review of the literature reveals that the study carried out in this research encompasses several elements of originality, as only very few similar works have been undertaken.

Flexicurity of the Labor Market through the Formal/Informal Duality, in the Context of Globalization
Authors: MARINESCU Cristian
Published: February 2022

The new stage of globalization, marked by deeper integration of work, creates new opportunities, both in terms of economic growth and job creation, but at the same time creates new challenges and problems in the labor market, such as: increasing labor market flows, exposing jobs to increased global competition and segmenting the labor market in formal and informal terms. It is known that the main feature of the informal labor market, whether we are talking about a developed economy or a developing economy, is flexibility, and the essential feature of a formal labor market is security. In any labor market, there is an increasingly fierce struggle between employers, who want more flexibility and employees, who want more security. Thus, was born the concept of "flexicurity". This paper aims to approach the flexicurity of the labor market through the formal / informal duality in the current context of globalization and to show the optimal combination of job flexibility and the security of the workers, who occupy those jobs.

Integrative Volume Status Assessment
Authors: Kearney David , Reisinger Nathaniel , Lohani Sadichhya
Published: February 2022

Volume status assessment is a critical but challenging clinical skill and is especially important for the management of patients in the emergency department, intensive care unit, and dialysis unit where accurate intravascular assessment is necessary to guide appropriate fluid management. Assessment of volume status is subjective and can vary from provider to provider, posing clinical dilemmas. Traditional non-invasive methods of volume assessment include assessment of skin turgor, axillary sweat, peripheral edema, pulmonary crackles, orthostatic vital signs, and jugular venous distension. Invasive assessments of volume status include direct measurement of central venous pressure and pulmonary artery pressures. Each of these has their own limitations, challenges, and pitfalls and were often validated based on small cohorts with questionable comparators. In the past 30 years, the increased availability, progressive miniaturization, and falling price of ultrasound devices has made point of care ultrasound (POCUS) widely available. Emerging evidence base and increased uptake across multiple subspecialities has facilitated the adoption of this technology. POCUS is now widely available, relatively inexpensive, free of ionizing radiation, and can help providers make medical decisions with more precision. POCUS is not intended to replace the physical exam, but rather to complement clinical assessment, guiding providers to give thorough and accurate clinical care to their patients. We should be mindful of the nascent literature supporting the use of POCUS and other limitations as uptake increases among providers and be wary not to use POCUS to substitute clinical judgement, but integrate ultrasonographic findings carefully with history and clinical examination.
Evaluation of Venous Congestion Using Beside Ultrasonography by the Nephrology Consultant: The VExUS Nexus
Authors: Koratala Abhilash
Published: February 2022

In patients with heart failure and cardiorenal syndrome, lingering congestion is associated with worse outcomes. As such, titrating diuretic or ultrafiltration therapy based on objective assessment of volume status plays a crucial role in the management of these patients. Conventional physical examination findings and parameters such as daily weight measurement are not always reliable in this setting. Recently, point of care ultrasonography (POCUS) has emerged as an attractive enhancement to bedside clinical examination in assessing fluid volume status. Specifically, Doppler ultrasound of the major abdominal veins gives additional information about end-organ congestion when used in conjunction with inferior vena cava ultrasound. Moreover, these Doppler waveforms can be monitored in real time to gauge the efficacy of decongestive therapy. Herein, we present a case that illustrates the utility of POCUS in the management of a patient with heart failure exacerbation.
Role of Point of Care Ultrasonography in Patients with COVID-19 Associated Acute Kidney Injury
Authors: Ross Daniel W. , Hasan Zubair
Published: February 2022

The severe acute respiratory virus covariate-2 (SARS CoV-2) that causes Corona Virus Disease 2019 (COVID-19) has affected more than 194 million people worldwide and has attributed to or caused more than 4 million deaths. Acute kidney injury (AKI) is a common complication of COVID-19. Point of care ultrasonography (POCUS) can be a useful tool for the nephrologist. POCUS can be used to elucidate the cause of kidney disease and then also help to manage volume status. Here, we review pearls and pitfalls of using POCUS to manage COVID-19 associated AKI with special attention to kidney, lung, and cardiac ultrasound.

Published: February 2022

Nowadays, huge digital images are used and transferred via the Internet. It has been the primary source of information in several domains in recent years. Blur image is one of the most common difficult challenges in image processing, which is caused via object movement or a camera shake. De-blurring is the main process to restore the sharp original image, so many techniques have been proposed, and a large number of research papers have been published to remove blurring from the image. This paper presented a review for the recent papers related to de-blurring published in the recent years (2017-2020). This paper focused on discussing various strategies related to enhancing the software's for image de-blur.  The aim of this research is to help researchers to understand the current algorithms and techniques in this field, and eventually may developing new and more efficient algorithms for enhancing blurred images.
Situation and Challenges of Sustainability in Africa
Authors: Lopez Moreno Andoni , Collado Cueto Luis A.
Published: February 2022

The paper addresses the situation and trends of African countries to achieve the SDGs of the United Nations 2030 Agenda. Africa has the most significant development challenges and the additional difficulty of addressing this process with remarkably expansive demographic dynamics that will double its population in the coming decades.

The paper's objective is to assess the situation of African countries to achieve the SDGs and group them to identify similar situations and prospects to meet economic, social, environmental and institutional challenges implicit in them.

Starting from a general analysis of the continent's situation and considering economic, social and environmental elements, the work delves into the state of each country regarding the achievement of the SDGs, taking for this the levels of progress achieved and the tendency towards the achievement of goals. With these variables, the analysis applies cluster analysis to assess which countries and regions of the continent are in a more and less favourable position concerning the achievement of the SDGs.

Based on the analysis, it is possible to conclude that most countries with the best prospects are in North Africa. In general, the North and South of the continent have a favourable position for achieving the SDGs with a social and economic nature. Concerning the environmental SDGs, the Central African countries have the best prospects, although the economic and social situation is, in general, particularly unfavourable.
A Comparative Analysis of ODA and IMF lending on Economic Inequality
Authors: Martínez-Chiluisa Nicolás Sebastían , Lacalle-Calderon Maricruz
Published: February 2022

This paper studies the effects of Official Development Assistance (ODA) and IMF lending on economic inequality and compares the effectiveness of both instruments. To this end, we analyze the channels through which each of these instruments contributes to the reduction of inequality. Then, we propose a panel data model for 85 countries from 2000 to 2019 to test the impact of these two mechanisms on the reduction of inequality. The results suggest that multilateral ODA is more effective in reducing inequality than its bilateral counterpart. Also, it is more effective than the IMF lending. However, our results do not allow to generalize these conclusions to a regional level due to the intrinsic heterogeneity of each region in the world.

Published: February 2022

Objetivo: Descrever, do ponto de vista das mulheres privadas de liberdade, como ocorre a assistência à saúde durante a gestação, parto e puerpério. Métodos: Pesquisa de revisão integrativa da literatura, com análise sistemática dos dados tendo como foco, o seguinte problema de pesquisa: “Qual a percepção da mulher privada de liberdade sobre a assistência à saúde recebida no pré-natal, parto e puerpério?”. Os dados utilizados no presente estudo foram obtidos na Biblioteca Virtual em Saúde (BVS).  Os descritores utilizados foram “Gestação”, “Maternidade”, “Preso”, “Prisão”. Resultados: Os estudos encontrados destacam a complexidade de vivenciar o processo gravídico-puerperal em situação de privação de liberdade. As percepções das mulheres revelam fragilidades na assistência materno-infantil nas penitenciárias. As relações são desumanas e podem ser evidenciadas pela fragilidade do pré-natal, ausência de acompanhante durante o parto e puerpério sem assistência. Considerações finais: A maioria das instituições necessitam de ajustes e adaptações para cumprir o que é preconizado pela legislação brasileira. Dessa forma, os direitos das mulheres e filhos são ignorados e reforçam a marginalidade dessa população. Alguns aspectos encontrados nos resultados não puderam ser discutidos com profundidade, devido à falta de literatura específica.
On differential geometry of ρ-dimensional complexes $C^{\rho}(1,1)$ of $m$-dimensional planes of the projective space $P^n$
Authors: Бубякин И.В. , Гоголева И.В.
Published: February 2022

Предметом исследования настоящей статьи является дифференциальная геометрия $ \rho$-мерных комплексов $C^{ \rho}$ $m$-мерных плоскостей в проективном пространстве $P^n$, содержащих конечное число торсов, для которых $n-m$ различных торсов имеют одну общую $(m + 1)$-мерную касательную плоскость к торсу, при этом те же $n-m$ различных торсов имеют одну общую характеристическую $(m-1)$-мерную характеристическую плоскость, общую для двух бесконечно близких образующих торса. Настоящая работа относится к исследованиям в области проективной дифференциальной геометрии на основе метода подвижного репера Э. Картана и метода внешних дифференциальных форм. Эти методы позволяют с единой точки зрения изучать дифференциальную геометрию подмногообразий различных размерностей грассманова многообразия, а также обобщить полученные результаты на более широкие классы многообразий многомерных плоскостей. Для изучения таких подмногообразий применяется грассманово отображение многообразия $G(m, n)$ на $(m + 1)(n-m)$-мерное алгебраическое многообразие $\Omega(m,n)$ пространства $P^N$, где $N=\left(\begin{array}{c}n+1\\m+1\\\end{array}\right)-1.$
On the value of using 3D-shape and electrostatic similarities in deep generative methods
Authors: Bolcato Giovanni , Heid Esther , Boström Jonas
Published: February 2022

Multi-parameter optimization, the heart of drug design, is still an open challenge. Thus, improved methods for automated compounds design with multiple controlled properties are desired. Here, we present a significant extension to our previously described fragment-based reinforcement learning method (DeepFMPO) for the generation of novel molecules with optimal properties. As before, the generative process outputs optimized molecules similar to the input structures, now with the improved feature of replacing parts of these molecules with fragments of similar 3D-shape and electrostatics. By performing comparisons of 3D-fragments, we can simulate 3D properties while overcoming the notoriously difficult step of accurately describing bioactive conformations. We developed a new python package, ESP-Sim, for the comparison of electrostatic potential and molecular shape, allowing the calculation of state-of-the-art partial charges (e.g., RESP with B3LYP/6-31G**) obtained using the quantum chemistry program Psi4. The new improved generative (DeepFMPO v3D) method is demonstrated with a scaffold-hopping exercise identifying CDK2 bioisosteres. All code is open-source and freely available.
