Published: November 2021

An experiment has been performed in four locations in Poland (Radzików, Leszno, Szelejewo and Nieznanice).Fifteen genotypes from three species (tall fescue - Festuca arundinacea, meadow fescue - F. pratensisand red rescue - F. rubra) were measured and observed during two consecutive years. Despite of phenologicalobservations (heading and flowering start dates), biometrical measurements (plant height, leaf dimension,number of generative stems etc.) and physiological trait (chlorophyll contents index) seed yield of singlepanicle, seed yield of plant and seed yield per plot (i.e. 50 plants) were determined.Significant effects of years, locations and genotypes were calculated for mentioned species for almost alltested traits. Multiple linear regression analysis was used to estimate major predictors of seed yield. It resultedin different numbers of predictors for different species. For meadow fescue five, for red fescue – three and fortall fescue – only two statistically significant predictors were selected. For all species leaf width and numberof generative stems were statistically significant and had positive weights. For meadow and red fescue – alsoseed yield from single inflorescence was significant with positive weight. Our results demonstrate that leafwidth together with number of steams and single panicle yield are the most important determinants of plantseed yield in three Festuca species.

Published: November 2021

The aim of the research, conducted at the Institute of Plant Genetics, Breeding and Biotechnology of the  University of Life Sciences in Lublin since 1982, is the systematic gathering and multi-annual characterization  of triticale accessions collected in the Polish gene bank, as well as regeneration of materials preserved in the seed stores in case of reduced germination capacity or a small sample of grains. Valorisation of accessions  is carried out in a 4-year cycle of field experiments and includes botanical identification and a description of morphological and useful traits (agricultural and qualitative), conducted every year according to the same methodology. The valorisation data include both traits determined in field evaluation (assessment of emergence, overwintering, lodging, fungal disease resistance, and heading and full maturity dates) and measurements of biometric features (plant height, spike length, number of spikelets per spike, number and weight of grains per spike, 1,000 grain weight, protein content in grain). As part of the research, accessions have been made available for use in breeding programmes and have been donated to research and development institutes as a broad spectrum of variation for genetic similarity analysis and to provide genetic sources of such traits as resistance to pre-harvest sprouting, response to toxic aluminium ions, and disease resistance.

Humic substances and significance of their application – a review
Authors: Kłeczek Aneta , Anielak Anna
Published: November 2021

This paper is based on recent articles regarding applications of humic substances (HSs). HSs are natural organic materials, which have a number of potential applications. Furthermore, HSs are cheap, widespread and obtainable from bio-waste materials. HSs can be used as organic compound sorbents or in detoxification. They are applied as organic additives due to their positive effect on soil and plants, even under stress conditions. HSs reduce water consumption and minimise environmental problems. HSs are utilised for the remediation of multi-metal contaminated soils and as substitutes for synthetic washing agents. From an environmental engineering point of view, it is beneficial to remove HSs from municipal management, where they are undesirable (by-products of disinfection) and to utilise them where they are valuable. The aim of this article is to provide a greater insight into research about the applications of HSs.
Improved rack and pinion drive
Authors: Sawicki Tadeusz
Published: November 2021

A typical rack and pinion drive set is comprised of a rack and a pinion. There is an inter-tooth clearance between the mating teeth of the rack and the pinion, which has advantages and disadvantages. The disadvantage of this clearance is the errors that occur in the positioning of the machine tool during set-up. Elimination of clearance between teeth is possible by using a pinion drive with two pinions. This ensures continuous contact between the teeth, regardless of the direction of machine movement.
These are found on new machines, while older machines do not have such a solution. This paper presents a solution with two pinions, which can be used in such older machines and which makes it possible to achieve qualitative parameters that were not possible before.

THE ASSOCIATION BETWEEN PARENTAL ATTACHMENT AND THE PARENTING: A REVIEW AND PRELIMINARY META-ANALYSIS
Authors: Huang Yi
Published: November 2021

According to the internal working model, attachment is rooted in one's previous interactive experience, which can affect further interpersonal relationships through reaction to others, including the parent-child relationships. However, no meta-analysis examining the link between parental attachments and parenting styles was done before. This meta-analysis study aimed to examine the associations between parents' patterns of attachment and parenting styles. Sixteen published articles and 2342 participants were included in the analysis. It was found that parental secure attachment correlated with positive parenting, but no significant negative correlation emerged between secure attachment and negative parenting. Regarding maternal insecure attachment, the results showed it correlated with positive parenting negatively and significantly. Also, there was a significant association between the insecure attachment and negative parenting. This research suggests that parental attachment pattern is linked to parenting styles.

Three new Noctuoidea subspecies are described as local endemics from the Silver Coast, part of the Bulgarian North Black Sea Coast: Eutelia adoratrix platinea ssp. n., Lacanobia praedita canescens ssp. n. and Hadena adriana petergyulaii ssp. n. They are characterised by a pale forewing ground colour corresponding to the colour of the calcareous sediments dominating their habitats. These new subspecies, in comparison with the nominotypical taxa, show greater differences in external appearance than in the female and male genitalia, including the everted vesica. Furthermore, the new subspecies cannot be separated from the nominotypical subspecies by DNA barcoding.

U radu je prezentirano prikupljeno meteorološko nazivlje koje je u koliziji s hrvatskim znanstvenim meteorološkim nazivljem. Prikupljanje podataka obavljano je u višegodišnjemu razdoblju u emisijama Hrvatske radiotelevizije (HRT) u kojima su sudjelovali meteorolozi Državnoga hidrometeorološkoga zavoda. Uočeno je da nazivlje samovoljno mijenjaju ne samo pojedini meteorolozi već da to čine i HRT-ovi lektori, a da ni jedno ni drugo meteorološka struka nije verificirala. Najveće promjene vidljive su u nazivlju naoblaka, temperatura, oborina i vjetar. Time je stvoreno paralelno nazivlje kojim se koristi na HRT-u i tako se prenosi korisnicima. Daljnja upotreba tako izmijenjena nazivlja rezultirala je bombastičnim i nesuvislim napisima u svim elektronskim i tiskovnim medijima. Sámo sudjelovanje meteorologa u „mijenjanju nazivlja“ ukazuje na njihovu nedovoljnu upućenost u meteorološko nazivlje. Posebno je na HRT-u problematična (ne)upotreba fizikalnih jedinica i njihova interpretacija te neopravdano mijenjanje stručnih pojmova mimo meteorologa.
High Circulating Sclerostin Level as Osteoporosis Risk Factor in Male Geriatric Population at Sanglah Hospital Bali
Authors: Suryarini Sandra , Kuswardhani RA. Tuty , Wiguna I. Gusti Lanang Ngurah Agung Artha
Published: November 2021

BACKGROUND: Osteoporosis is a disease characterized by low bone mass and structural deterioration of bone tissue, leading to bone fragility. The development of biomolecular world found Wnt/β-catenin signaling pathway may plays an important role in bone mass regulation. Osteoporosis in geriatric population remains one of global health problems and typically thought of as a disease impacting women, but recently increasing attention is being paid to osteoporosis in males. Osteoporosis in male accounts for higher morbidity and mortality compare to woman population. The association between sclerostin serum and risk for osteoporosis in male geriatric will be described as follows.
METHODS: This study is a case–control study with a total 54 samples of male geriatrics, divided into 27 non- osteoporosis subjects and 27 osteoporosis subjects (age ≥60 years old). Diagnosis of osteoporosis was defined according to the WHO criteria based on bone mineral density. All participants were scanned on a GE lunar prodigy bone densitometer. Sclerostin serum level was measured using enzyme-linked immunosorbent assay (ELISA).
RESULTS: The average age from total 54 samples in case group was 69.81 ± 6.5 years old and control 69.41 ± 5.97 years old. Cutoff value based on receiver operating characteristic curve for sclerostin serum level was 302.5 pg/mL where the sensitivity and specificity for developing osteoporosis in male geriatrics were 59.3% and 81.5%, respectively. Male geriatrics with sclerostin serum ≥302.5 pg/mL is 6.4 times more likely to developed osteoporosis than those with sclerostin serum <302.5 pg/mL (OR = 6.4; p = 0.0020; CI 95% = 1.856–22.068). Multivariate logistic regression analysis after controlling other variables such as bone mass index, age, smoking status, alcohol consumption, physical activity, sun exposure, and type II diabetes mellitus showed that high sclerostin level was an independent susceptibility factors for osteoporosis in male geriatrics population (p = 0.001).
CONCLUSIONS: This study showed that high circulating sclerostin serum (≥302.5 pg/mL) was risk factor for developing osteoporosis in male geriatrics.

Quelles compétences pour quelle compétitivité ?
Authors: Cadix Alain
Published: November 2021

La France doit résoudre un problème de compétitivité de son industrie et un problème de niveau de qualification (donc de compétence) de sa population active. Les deux sont liés. L’organisation, le capital humain et le management sont trois leviers primordiaux de la compétitivité des entreprises (loi OHM). Les compétences technologiques constituent une composante majeure du capital humain. Elles sont marquées par l’instabilité et l’imprévisibilité de la diffusion de technologies clés, à quoi s’ajoute leur hybridation. Cela appelle des compétences nouvelles. Les compétences collectives, essentielles pour que l’entreprise innove ou s’adapte, sont déterminées par des compétences transversales. La qualité de l’organisation et du management y contribue. Dans ce contexte, les politiques centrées sur les qualifications, au niveau de l’entreprise comme au niveau de la société, sont déterminantes. Le retour en force de l’industrie ne pourra s’opérer qu’en s’appuyant sur des qualifications adaptées aux nouveaux contextes.
Pourquoi la recherche académique française souffre-t-elle d’une perte d’attractivité ?
Authors: Mignon Valérie
Published: November 2021

Dans cet article, nous présentons les raisons pour lesquelles la recherche académique française perd du terrain sur la scène scientifique internationale. Après avoir dressé un état des lieux général de la recherche en France, nous nous consacrons au cas particulier du système universitaire français. Nous mettons en avant le fait que les difficultés budgétaires des universités, le manque de financements récurrents des laboratoires, le déficit de moyens humains, la lourdeur et la multiplicité des tâches administratives, la faible attractivité des salaires et des carrières dans le milieu académique, mais aussi les freins aux partenariats entre recherche publique et recherche privée constituent des défis à relever afin que la France retrouve une position de premier plan dans la recherche au niveau mondial.
Pornographie, vulnérabilités et abus sexuels : défis et possibles solutions
Authors: Vinciguerra Tebaldo
Published: November 2021

La pornographie crée des situations de vulnérabilité et de dépendance. Sa diffusion capillaire et son influence (dès l’enfance) contribuent à son dédouanement. Nombre de scénarios pornographiques dépeignent des abus sexuels, et certaines situations de vulnérabilité les facilitent. Cela requiert une ample prise de conscience et une réaction multi-niveaux fédérant tous les acteurs de la société ; l’enseignement social de l’Eglise Catholique peut fournir des points de repère utiles.

The damping term makes the Smale-horseshoe heteroclinic chaotic motion easier
Authors: Sun Huijing , Cao Hongjun
Published: November 2021

The nonlinear Rayleigh damping term that is introduced to the classical parametrically excited pendulum makes the parametrically excited pendulum more complex and interesting. The effect of the nonlinear damping term on the new excitable systems is investigated based on analytical techniques such as Melnikov theory. The threshold conditions for the occurrence of Smale-horseshoe chaos of this deterministic system are obtained. Compared with the existing conclusion, i.e. the smaller the damping term is, the easier the chaotic motions become when the damping term is linear, our analysis, however, finds that the smaller or the larger the damping term is, the easier the Smale-horseshoe heteroclinic chaotic motions become. Moreover, the bifurcation diagram and the patterns of attractors in Poincaré map are studied carefully. The results demonstrate the new system exhibits rich dynamical phenomena: periodic motions, quasi-periodic motions and even chaotic motions. Importantly, according to the property of transitive as well as the fractal layers for a chaotic attractor, we can verify whether a attractor is a quasi-periodic one or a chaotic one when the maximum lyapunov exponent method is difficult to distinguish. Numerical simulations confirm the analytical predictions and show that the transition from regular to chaotic motion.

Moreover, when \begin{document}$ n = 3 $\end{document}, the result is best possible, i.e., every \begin{document}$ 3\times 3 $\end{document} stable matrix with five or fewer nonzero entries will not exhibit Turing instability. Furthermore, we determine all possible \begin{document}$ 3\times 3 $\end{document} irreducible sign pattern matrices with 6 nonzero entries which can be realized by a matrix \begin{document}$ A $\end{document} that exhibits Turing instability.

Precisely, we establish a general and optimal decay result for a large class of relaxation functions which improves and generalizes several stability results in the literature. In particular, our result extends an earlier one in the literature, namely, the case of the polynomial rates when \begin{document}$ H(t) = t^p, \ t\geq 0, \forall p>1 $\end{document}, instead the parameter \begin{document}$ p \in [1, \frac{3}{2}[ $\end{document}.
Analysis on a diffusive SEI epidemic model with/without immigration of infected hosts
Authors: Lei Chengxia , Shen Yi , Zhang Guanghui , Zhang Yuxiang
Published: November 2021

In this paper, we study a reaction-diffusion SEI epidemic model with/without immigration of infected hosts. Our results show that if there is no immigration for the infected (exposed) individuals, the model admits a threshold behaviour in terms of the basic reproduction number, and if the system includes the immigration, the disease always persists. In each case, we explore the global attractivity of the equilibrium via Lyapunov functions in the case of spatially homogeneous environment, and investigate the asymptotic behavior of the endemic equilibrium (when it exists) with respect to the small migration rate of the susceptible, exposed or infected population in the case of spatially heterogeneous environment. Our results suggest that the strategy of controlling the migration rate of population can not eradicate the disease, and the disease transmission risk will be underestimated if the immigration of infected hosts is ignored.

Image fusion network for dual-modal restoration
Authors: Zhang Ying , Ren Xuhua , Clifford Bryan Alexander , Wang Qian , Zhang Xiaoqun
Published: November 2021

In recent years multi-modal data processing methods have gained considerable research interest as technological advancements in imaging, computing, and data storage have made the collection of redundant, multi-modal data more commonplace. In this work we present an image restoration method tailored for scenarios where pre-existing, high-quality images from different modalities or contrasts are available in addition to the target image. Our method is based on a novel network architecture which combines the benefits of traditional multi-scale signal representation, such as wavelets, with more recent concepts from data fusion methods. Results from numerical simulations in which T1-weighted MRI images are used to restore noisy and undersampled T2-weighted images demonstrate that the proposed network successfully utilizes information from high-quality reference images to improve the restoration quality of the target image beyond that of existing popular methods.

Several studies have shown a link between immunity, inflammatory processes, and epilepsy. Active neuroinflammation and marked immune cell infiltration occur in epilepsy of diverse etiologies. Microglia, as the first line of defense in the central nervous system, are the main effectors of neuroinflammatory processes. Discovery of new biomarkers associated with microglia activation after epileptogenesis indicates that targeting specific molecules may help control seizures. In this research, we used a combination of several bioinformatics approaches, including RNA sequencing, to explore differentially expressed genes (DEGs) in epileptic lesions and control samples, and to construct a protein-protein interaction (PPI) network for DEGs, which was examined utilizing plug-ins in Cytoscape software. Finally, we aimed to identify 10 hub genes in immune and inflammation-related sub-networks, which were subsequently validated in real-time quantitative polymerase chain reaction analysis in a mouse model of kainic acid-induced epilepsy. The expression patterns of nine genes were consistent with sequencing outcomes. Meanwhile, several genes, including CX3CR1, CX3CL1, GPR183, FPR1, P2RY13, P2RY12 and LPAR5, were associated with microglial activation and migration, providing novel candidate targets for immunotherapy in epilepsy and laying the foundation for further research.

In various pathological conditions such as diabetes mellitus, the cellular redox balance can be disturbed and these alterations may persist even after blood glucose levels have returned to normal. Antioxidant therapies, including α-lipoic acid, are widely used to treat various systemic diseases including diabetes mellitus. The aim of this study was to measure the lipid metabolism parameters, as well as the activity of lipid peroxidation and antioxidant defense reactions, in men with type 1 diabetes mellitus (T1DM) during treatment with α-lipoic acid. Twenty-four reproductive-age T1DM males with an unsatisfactory glycemic profile were examined. Twenty-eight practically healthy men of similar age were used as the control group. Spectrophotometric, fluorometric, and enzyme-linked immunoassay methods were used. T1DM was characterized by increased values of lipid metabolism components, including total cholesterol, triacylglycerides (TG), and very-low-density lipoproteins (VLDL). In the lipid peroxidation system, increased levels of the primary products (conjugated dienes), secondary products (thiobarbituric acid reactants), and final products (Schiff bases) were observed in T1DM patients compared to the control group. Retinol values were also increased. After treatment, there was a decrease in TG, VLDL, and Schiff bases levels and an increase in the retinol level compared to before treatment. These results expand our understanding of the pathogenetic mechanisms of T1DM and suggest that α-LA treatment may be beneficial for type 1 diabetics.
Can an Avian Electrocution Risk Model From California Guide Retrofitting Throughout the Western United States?
Authors: Dwyer James F. , Mojica Elizabeth K.
Published: November 2021

A previously published model of avian electrocution risk, the “2014 model,” compared power poles that electrocuted birds (electrocution poles; including 21 golden eagle Aquila chrysaetos electrocutions) with poles not known to have electrocuted birds (comparison poles). The 2014 model produces pole-specific risk index scores between 0 and 1. The scores rank relative risk so electric utilities can maximize conservation benefits per dollar spent by focusing retrofitting on poles with greatest risk. Although the creation of the 2014 model encompassed a study population of birds and poles in southern California, the 2014 model has potential for use in managing a target population of raptors including golden eagles throughout the western United States. Use beyond southern California is only appropriate if the study population is similar enough to the target population for the 2014 model to predict risk effectively. To evaluate similarity, we examined five sources of evidence: 1) the relative consistency in electrical safety codes for power poles; 2) the body sizes of golden eagles in the study and target populations; and consistency in structure-specific factors associated with 3) golden eagle electrocutions in other studies, 4) other avian electrocutions, and 5) previously unreported golden eagle electrocutions. We found that although the study population in the 2014 model included relatively few golden eagles, data were sufficient to create a model that is applicable to a target population throughout the western United States. The model also can be useful in helping determine equivalencies between pole types if utilities seek to compare benefits of retrofitting small numbers of high-risk poles with large numbers of low-risk poles.

L’anticléricalisme dans l’Égypte coloniale. Le cas de la colonie italienne (1860-1914)
Authors: Paonessa Costantino
Published: November 2021

De façon similaire à ce qui se passait dans le reste des territoires soumis à l’Empire ottoman, dans les principales villes égyptiennes, tout au long du xixe siècle, des intellectuels ont circulé, constitué des groupes et des courants de pensée inspirés par le laïcisme, la libre‑pensée, l’anticléricalisme, le scepticisme matérialiste et l’athéisme. Dans cet article, je me concentrerai sur la reconstruction historique de ces mouvements et courants de pensée à l’intérieur de la colonie italienne d’Égypte avant la Première Guerre mondiale. Ce cas spécifique nous permettra d’observer, avec une perspective totalement inédite, certains enjeux sociaux, politiques et culturels qui ont affecté le microcosme italien à l’intérieur des dynamiques propres à un territoire colonisé.

Authors: O’Kane Bernard
Published: November 2021

Antonio Lasciac was one of the most active of European architects working in Egypt in the late nineteenth and early twentieth century. His output was as eclectic as it was prolific, comprising buildings and decoration in neo‑Renaissance, neo‑Gothic and neo‑Mamluk styles. This paper focuses on of the origins of the motifs on his buildings decorated in Mamluk revival style, and particularly on his villa at Rafut, in Slovenia, beside the modern border of Gorizia in Italy. The paper first gives a background to the rise of the neo‑Mamluk style in Egypt before analyzing Lasciac’s contributions to it. In one of his early buildings, the neo‑Renaissance palace of Yūsuf Kamāl at Matariyya, a newly‑discovered neo‑Mamluk room is discussed. The detailed analysis of his villa at Rafut and later buildings show the unusual extent to which the decorative motifs he used were accurately based on earlier Mamluk designs, reflecting his long‑standing involvement as a board member of the Comité de conservation des monuments de l’art arabe.

In this modern era of digitalization and consumer awareness regarding food safety issues, it has become important to build proper strategies that can ensure the quality and safety of the food items from farm to forks. People love to eat at restaurants not only during business meetings but also with their family for fun and entertainment. The choice and safety of the food is vital to attract the consumer in this competitive environment. Previously, conventional methods have been employed for assurance of quality and safety parameters of the food. But in this modern era, there are many potential alternatives that can serve the purpose rapidly and non-destructively. Hence, this chapter describes the rapid and non-destructive methodologies such as fluorescence, NIRS, MIR, and Raman spectroscopy that can be used for the food safety evaluations.

Pure niobium substrates were coated using laser cladding method. Pure molybdenum, Yttria Stabilized Zirkonia (YSZ) and corundum (Al2O3) powders were used as coating materials. Coatings were deposited on specimens as seperate paths with 3÷10mm width and 40mm of length. Two different laser power 3kW and 4kW were tested during deposition. In order to assess the quality of the Mo-YSZ and Mo-Al2O3 coatings, the light microscopy, Scanning Electron Microscopy (SEM), chemical analysis (EDS) and Vickers hardness test investigation were performed. The surface roughness and wear volume were also measured. As a result of YSZ-Mo powder cladding on the Nb substrate the composite layers were obtained without cracks and porosity not exceeding 1 μm. In addition, an increase in hardness of about 450 HV0.5 was revealed. As a result of Al2O3-Mo powder cladding on the Nb substrate the composite layers with many voids and cracks were obtained for each of the cladding variants.
Pasarlo bien juntos: experiencias y significados sobre participación estudiantil desde la voz de niños y niñas
Authors: Urbina Hurtado Carolina , Allende Silva Patricia , Carrasco-Aguilar Claudia , Durán Camila
Published: November 2021

El propósito de este estudio fue comprender los significados sobre participación desde la voz de estudiantes de una escuela de la región de Valparaíso, quienes fueron convocados a compartir su experiencia en talleres grupales y entrevistas ad hoc. A partir de un análisis categorial temático de contenido de la información producida, se identificaron tres aspectos principales de la experiencia estudiantil: participar significa “pasarlo bien juntos”, siendo la diversión, cooperación y pertenencia a una comunidad aspectos centrales de la experiencia; los espacios de participación son interferidos por un adulto excluyente que beneficia a estudiantes con un perfil “esperado”, y las vivencias más significativas se desarrollan en espacios escolares informales. Los resultados evidencian la tensión derivada de la disputa entre poderes dentro de la escuela, que reclama la construcción de una escuela más democrática y atenta a la creación de entornos ciudadanos que sintonice y valore la perspectiva estudiantil.
Commutativity via spectra of exponentials
Authors: Brits Rudi , Schulz Francois , Touré Cheick
Published: November 2021

Let A be a semisimple, unital, and complex Banach algebra. It is well known and easy to prove that A is commutative if and only
$e^xe^y=e^{x+y}$
for all
$x,y\in A$
. Elaborating on the spectral theory of commutativity developed by Aupetit, Zemánek, and Zemánek and Pták, we derive, in this paper, commutativity results via a spectral comparison of
$e^xe^y$
and
$e^{x+y}$
.
Generalization of Klain’s theorem to Minkowski symmetrization of compact sets and related topics
Authors: Ulivelli Jacopo
Published: November 2021

We shall prove a convergence result relative to sequences of Minkowski symmetrals of general compact sets. In particular, we investigate the case when this process is induced by sequences of subspaces whose elements belong to a finite family, following the path marked by Klain in Klain (2012, Advances in Applied Mathematics 48, 340–353), and the generalizations in Bianchi et al. (2019, Convergence of symmetrization processes, preprint) and Bianchi et al. (2012, Indiana University Mathematics Journal 61, 1695–1710). We prove an analogous result for fiber symmetrization of a specific class of compact sets. The idempotency for symmetrizations of this family of sets is investigated, leading to a simple generalization of a result from Klartag (2004, Geometric and Functional Analysis 14, 1322–1338) regarding the approximation of a ball through a finite number of symmetrizations, and generalizing an approximation result in Fradelizi, Làngi and Zvavitch (2020, Volume of the Minkowski sums of star-shaped sets, preprint).
Globalization of capital, erosion of economic policy sovereignty, and the lessons from John Maynard Keynes
Authors: Bossone Biagio
Published: November 2021

This article observes that current macroeconomic policy modeling, centered on domestic agents or agencies, fails to recognize the role that global investors play in determining the space for effective domestic macroeconomic policies, and argues that these actors must be brought to the center of macro analysis if one wants to understand how policies work in the global financial context. The article describes the key features of global investors, discusses their power to determine the prices at which public-sector liabilities (money and debt) trade in the international markets, and considers how this power affects the effectiveness of macroeconomic policies by national governments. As a result, no government is truly sovereign in a globalized world, and every government is subject to an intertemporal budget constraint (IBC), although, of course, not all governments are born equal and not all IBCs are equally binding: government IBCs are elastic, endogenous to global investor decisions, and yet ineluctable. The article concludes that choosing the correct country policy stance in today's financial global context would benefit from revisiting some of the key policy lessons that John Maynard Keynes left with us, considering his deep knowledge of global financial markets and how they affect country economies.

Published: November 2021

La presente investigación tiene el propósito de analizar el aprendizaje de la matemática en función de los errores algebraicos en la U.E “Velasco Ibarra” perteneciente al cantón Guamote, provincia de Chimborazo, del nivel de educación general básica. Se parte del planteamiento que el aprendizaje no es una facultad específica de los humanos, se dice que aprenden debido a la práctica o a la experiencia, para ello se define aprendizaje como proceso de habilidades y destrezas, el aprendizaje de las matemáticas es complejo, se dice tanto que los estudiantes como los docentes influyen en una decisión en el éxito del proceso de aprendizaje y enseñanza de las matemáticas, el teorema va más allá de un enunciado el significado de entender un teorema algebraico deberá darse en términos, los errores en las matemáticas no son cometidos solamente por los estudiantes si  no por los docentes o matemáticos profesionales, los errores algebraicos son fuente de conocimiento que podemos explotar para profundizar en el pensamiento matemático

Atrasado para a revolução ou como sobreviver ao processo contrarrevolucionário: a experiência de exílio de Augusto Boal em Portugal
Authors: Batista Natália
Published: November 2021

Este artigo pretende investigar o primeiro ano do exílio do teatrólogo brasileiro Augusto Boal em Portugal, que viveu no país entre os anos de 1976 e 1978. Diante de uma vasta produção sobre o deslocamento de intelectuais e artistas brasileiros para o país, o interesse será mapear alguns aspectos da trajetória do diretor teatral no país lusitano. Serão analisados dois elementos específicos: as motivações para o seu deslocamento e a sua chegada da cidade de Lisboa. Em um primeiro momento, interessa compreender como a Revolução dos Cravos modificou o contexto português e fomentou em Boal o desejo de participação em um processo revolucionário que colocou fim na ditadura do regime salazarista. Em um segundo momento busca-se analisar as redes de sociabilidade que permitiram o deslocamento de Boal para Lisboa, assim como a análise das dificuldades encontradas no momento inicial de sua chegada em sua relação com a Secretaria de Estado da Cultura portuguesa. Devido a problemas com a burocracia brasileira para a renovação de seu passaporte, Boal chegou no país dois anos após a data inicial da revolução. Diante das incertezas do processo pós-revolucionário, a presença de Boal se tornou um objeto de disputa dentro do governo. As promessas de trabalho feitas pelo Estado português se concretizaram parcialmente e foram cercadas de percalços. Busca-se analisar as categorias de engajamento e exílio para descortinar possibilidades interpretativas e sugerir novos olhares sobre a experiência inicial de Boal durante o seu exílio em Lisboa.
Sobre la lucha de Ser Mujeres: subjetividades políticas femeninas
Authors: Díaz Alzate Magda , Duran Palacio Nicolasa , Gómez Durán Deysafira
Published: November 2021

Este artículo presenta la supracategoría “La Lucha de Ser Mujeres” como resultado de una investigación cualitativa realizada en Medellín, Colombia, con enfoque feminista que pretendía develar los modos en que se configuran las subjetividades políticas femeninas en un grupo de mujeres jóvenes. Se halló que las mujeres se enfrentan a luchas cotidianas en las familias por su reconocimiento como interlocutoras válidas y por configurarse como mujeres diferentes a la concepción de mujer impuesta por los discursos patriarcales. Los modos que han encontrado para rebelarse y resignificarse pasan necesariamente por los encuentros colectivos con otras mujeres y por el caminar la palabra para comprenderse diferentes y diferenciadas, plurales y con poder de participación y de decisión sobre sí mismas y en los escenarios públicos.
