Published: August 2021

El presente texto resulta de nuestras reflexiones sobre las prácticas de Educación Popular; expone rasgos de la actual organización social latinoamericana y busca caracterizar las formas de investigación social que dan apoyo a las personas, movimientos e instituciones sociales cuya actividad es de resistencia a la geopolítica actual, que nos domina y reproduce formas eurocéntricas en la producción del conocimiento. Pretendemos, con ello, apoyar el debate actual sobre las epistemologías del sur, en especial las que han sido creadas en nuestra América. Queremos, en particular, contribuir con el debate de maestros y maestras que hoy buscan promover prácticas educativas diversas y humanas, no sometidas a la racionalidad económica de la  acumulación y de la expansión del capital

Los aprendizajes no intencionados en la complejidad del ambiente escolar: asunto emergente y posibilitador de acciones para la paz
Authors: Becerra Martínez James Frank , Cárdenas Forero Oscar Leonardo , Moncada Rodríguez María Anais , Negrete Soler Edith Constanza , Prieto Acuña Ángela , Uribe Garzón Sonia Milena
Published: August 2021

En las interacciones del ambiente escolar existen ciertos aprendizajes que no surgen necesariamente de los contenidos curriculares, actividades académicas o intenciones pedagógicas del maestro, sino que involucran formas de lenguaje, comportamientos, actitudes y expresiones no explícitas en esas gestiones, pero visibles en las dinámicas de convivencia de los estudiantes. Estas particulares formas de relacionarse suceden sin la mediación directa de la institución escolar, convirtiéndose en aprendizajes que revisten de gran importancia porque son marcadores de las relaciones de convivencia, potenciadores o inhibidores de los aprendizajes escolares y de los actos de paz en la escuela. Son ellos el punto de partida para el presente artículo.

Bioconstrução Coletiva na Aldeia Itapoã Tupinambá de Olivença, Ilhéus, BA, Brasil
Authors: Dos Santos Souza Leandro Ricardo , Rodrigues dos Santos Vanessa , Costa Silvia
Published: August 2021

O presente texto aborda, por meio do relato de experiência, o processo de aprimoramento da tecnologia bioconstrutiva vernacular de edificações na aldeia indígena Itapoã Tupinambá, localizada no distrito de Olivença, município de Ilhéus/BA, Brasil. As atividades pautaram-se na abordagem teórico-metodológica da pesquisa-ação, uma vez que a construção vernacular não pode ser dissociada do coletivo representativo da realidade investigada. As atividades contemplaram: a) registro em diário de campo; b) análise de patologias de edificações através de um roteiro de observação direcionada; e c) oficinas de bioconstrução. Observou-se que as edificações da aldeia são predominantemente construídas com terra, utilizando a tecnologia bioconstrutiva do pau-a-pique. Constataram-se patologias referentes à deterioração, irregularidades e fissuras provocadas pela retração do barro. A partir de vivências de bioconstrução, foi possível aprimorar a argamassa natural utilizada, contribuindo para melhoria do desempenho estrutural das edificações em curto e médio prazos. Concluiu-se que a manutenção da bioconstrução em pau-a-pique retarda o impacto ambiental resultante do uso de materiais convencionais, além de assegurar aspectos socioculturais intrínsecos ao processo de construção em mutirão na comunidade.
A note on meromorphic functions with finite order and of bounded l-index
Authors: Bandura Andriy
Published: August 2021

We present a generalization of concept of bounded $l$-index for meromorphic
functions of finite order. Using known results for entire functions of bounded $l$-index
we obtain similar propositions for meromorphic functions.
There are presented analogs of Hayman's theorem and logarithmic criterion for this class.
The propositions are widely used to investigate $l$-index boundedness of entire solutions of differential equations.
Taking this into account we raise a general problem of generalization of some results from theory of entire functions of bounded $l$-index by
meromorphic functions of finite order and their applications to meromorphic solutions of differential equations.
There are deduced sufficient conditions providing $l$-index boundedness of meromoprhic solutions of finite order
for the Riccati differential equation. Also we proved that the Weierstrass $\wp$-function has bounded $l$-index with
$l(z)=|z|.$
Relation between Fourier series and Wiener algebras
Authors: Trigub Roald
Published: August 2021

New relations between the Banach algebras of absolutely convergent Fourier integrals of complex-valued measures of Wiener and various issues of trigonometric Fourier series (see classical monographs by A.~Zygmund [1] and N. K. Bary [2]) are described. Those bilateral interrelations allow one to derive new properties of the Fourier series from the known properties of the Wiener algebras, as well as new results to be obtained for those algebras from the known properties of Fourier series. For example, criteria, i.e. simultaneously necessary and sufficient conditions, are obtained for any trigonometric series to be a Fourier series, or the Fourier series of a function of bounded variation, and so forth. Approximation properties of various linear summability methods of Fourier series (comparison, approximation of function classes and single functions) and summability almost everywhere (often with the set indication) are considered. The presented material was reported by the author on 12.02.2021 at the Zoom-seminar on the theory of real variable functions at the Moscow State University.

Obstructive uropathy secondary to perforated appendicitis.
Authors: Moyano Portillo Á , Garrido Márquez I , Fernández Navarro L
Published: August 2021

Existen publicaciones en la literatura en las que la presentación clínica "clásica" de apendicitis se ha visto acompañada de una dilatación de la vía urinaria. La razón a esta situación es la inflamación periapendicular que se produce en algunas apendicitis que por vecindad puede englobar la vía urinaria y producir su obstrucción. El uréter más comúnmente implicado es el derecho por su localización anatómica, aunque existen algunos casos descritos de hidronefrosis bilateral secundaria.

El tratamiento es quirúrgico mediante exéresis del apéndice, necesitando en contadas ocasiones de una derivación urinaria tipo nefrostomía o catéter doble J que alivie la presión en la vía urinaria.

Los médicos debemos de ser conscientes de la hidronefrosis como una complicación atípica de la apendicitis aguda, especialmente cuando se presenten los signos clásicos de apendicitis junto a dolor en fosa renal y dilatación de la vía urinaria en los estudios de imagen.

EXPANDING DEPTH AND MEANING WITHIN URBAN DESIGN PROCESSES THROUGH THE APPLICATION OF COMPLEXITY AND EVOLUTIONARY THEORIES
Authors: Miguel Marta , Laing Richard , Leon Marianthi , Baxter Seaton
Published: August 2021

Previous research has established the value of regarding cities as complex systems, and as systems which will evolve over time. The research reported in this paper concerns the development of an approach to urban design and management which recognises the complexities of change resulting from design-led urban interventions. The research commenced with a study of urban design and urban management processes, and the manner in which they have been studied in an academic context. The system aims to guide the processes of urban design so that it can be implemented within a cyclical process of evaluation and application. The system aids communication across design teams and improves clarity within the design process for the designers themselves. The specific system also aspires to interconnect theory with practice, while supporting designers to be inclusive and holistic. The paper describes a case study where the framework was applied within an academic setting, related to real urban environments in Singapore. It validates the model’s ability to guide students through the design process, give depth to their analysis of urban systems and meaning to their designs. Action research was implemented, to reflect the need for a “practice-changing practice” methodology, that supports a greater understanding of the relationship between theory and practice.
DETERMINANTS OF PLATFORM ECOSYSTEM HEALTH: AN EXPLORATION BASED ON GROUNDED THEORY
Authors: Chen Yun , Sun Yaowu
Published: August 2021

Whether the platform ecosystem operates well influences the survival and development of all actors. Drawing on the literature of business ecosystem health, we propose the topic of platform ecosystem health, which refers to a stable and sustainable operating status obtained through cooperation among actors that can effectively respond to turbulent changes, meet market demand, and make profit. Platform ecosystem health is complexly influenced by internal and external factors, and exploring these is the first step towards its improvement. To address this question, this study uses grounded theory to identify the main determinants and theoretically explain the ways in which these determinants influence platform ecosystem health. Specifically, we select 15 representative platform ecosystems in the mobile communication services, e-commerce, and high-tech manufacturing industries using theoretical sampling. Three encoding processes and theoretical saturation tests are then employed to analyze interview and secondary data on the health of these platform ecosystems. Based on the identified 132 concepts and nine categories, we obtain four types of determinants: dominant capabilities of the platform enterprise, cooperation potential of the complementary enterprise, products and services, and industry environment. We finally propose four propositions to illustrate the relationships between the determinants and platform ecosystem health.
Mapping Stellar Surfaces. I. Degeneracies in the Rotational Light-curve Problem
Authors: Luger Rodrigo , Foreman-Mackey Daniel , Hedges Christina , Hogg David W.
Published: August 2021

Thanks to missions like Kepler and TESS, we now have access to tens of thousands of high-precision, fast-cadence, and long-baseline stellar photometric observations. In principle, these light curves encode a vast amount of information about stellar variability and, in particular, the distribution of starspots and other features on their surfaces. Unfortunately, the problem of inferring stellar surface properties from a rotational light curve is famously ill-posed, as it often does not admit a unique solution. Inferences about the number, size, contrast, and location of spots can therefore depend very strongly on the assumptions of the model, the regularization scheme, or the prior. The goal of this paper is twofold: (1) to explore the various degeneracies affecting the stellar light-curve “inversion” problem and their effect on what can and cannot be learned from a stellar surface, given unresolved photometric measurements, and (2) to motivate ensemble analyses of the light curves of many stars at once as a powerful data-driven alternative to common priors adopted in the literature. We further derive novel results on the dependence of the null space on stellar inclination and limb darkening and show that single-band photometric measurements cannot uniquely constrain quantities like the total spot coverage without the use of strong priors. This is the first in a series of papers devoted to the development of novel algorithms and tools for the analysis of stellar light curves and spectral time series, with the explicit goal of enabling statistically robust inferences about their surface properties.
Ypsolopha chicoi sp. n., the second representative of the widespread micromoth genus Ypsolopha Latreille (Lepidoptera, Ypsolophidae) from the Andes of northern Chile
Authors: Vargas Héctor
Published: August 2021

The largest number of species of the widespread and highly diverse micromoth genusYpsolophaLatreille, 1796 (Lepidoptera, Yponomeutoidea, Ypsolophidae) is known from the Northern Hemisphere. Only seven species have been described from the Neotropical Region, two of which occur in Chile.

The adult stage ofYpsolopha chicoisp. n. from the arid highlands of the western slopes of the Andes of northern Chile is described and illustrated. Its larvae feed on the native shrubMuehlenbeckia fruticulosa(Walp.) Standl. (Polygonaceae). The morphology of the genitalia ofY. chicoisp. n. resembles that of the only congeneric known to occur in the same geographic area,Y. molteniiVargas, 2018, whose larvae feed onAdesmia verrucosaMeyen (Fabaceae). Besides using different host plants, the two species can be accurately separated, based on morphological differences in female and male genitalia.
Erythropoetin and Erythropoetin Receptor Systems, and Oxidative Status in Patients with Basal Cell Carcinoma
Authors: Kurutas Ergul Belge , Ozturk Perihan
Published: August 2021

Introduction: Erythropoietin (Epo) controls a variety of signal transduction pathways during oxidative stress. The main function of Epo and its receptor (EpoR) is the stimulation of erythropoiesis. 

Aim: The role of Epo and EpoR on non-hematopoietic normal and cancerous tissues is still poorly understood. This is the first report in which we aimed to investigate the role of Epo and EpoR systems at oxidative condition in human basal cell carcinoma (BCC), which is the most common tumour in the world.Materials and methods: Fresh normal and cancerous skin paired tissue was obtained from 63 patients who underwent curative BCC resection in Kahramanmaras, Turkey. Preliminary diagnosis of BCC was made in the dermatology clinic by excision and then the diagnosis was confirmed as histopathologic findings. Oxidative stress biomarkers such as superoxide dismutase (SOD) and catalase (CAT) activities, and malondialdehyde (MDA) levels in biopsy samples were measured spectrophotometrically, and also the levels of Epo and EpoR were measured by ELISA. 

Results: While the levels of MDA in cancerous tissue of patients with skin BCC were significantly higher than normal neighbouring skin tissue (p<0.05), SOD and CAT activities decreased (p<0.05). Furthermore, a remarkable increase was found in the Epo level ofpatients with skin BCC in comparison with the normal neighbouring skin tissue (p<0.05). However, we found that EpoR levelsdecreased (p<0.05). 

Conclusions: Results indicate that there is an active oxidative process in BCC biopsies. The levels of increased Epo and decreased EpoR in oxidative condition due to hypoxia may aggravate tumour growth by its angiogenic activity.
Parental knowledge of dental erosion and erosion-related risk factors in children
Authors: Nihtyanova Tanya , Sapunarova Plamena , Belcheva-Krivorova Ani , Petrova Svetla
Published: August 2021

Introduction: Dental erosion in children has been steadily on the increase in recent years. This is mainly due to the contemporary eating habits of the new generations and their upbringing from an early age to prefer foods and beverages with high acid content.

Aim: To study the knowledge of parents about dental erosion and the most common risk factors associated with it.

Materials and methods: Data were gathered through a direct individual questionnaire administered to the parents of children aged 3 to 5 years. The results were analyzed by descriptive statistics and the Pearson chi-squared test for independence using SPSS 19.

Results: A large proportion of respondents (68.5%) stated that they knew what dental erosion was. Most of them (77.4%) were aware of the detrimental effect of carbonated beverages. In contrast, only 23.8% were aware of the potentially harmful effect of excessive consumption of citrus fruits, and only 31.9% of parents considered the impact of excessive intake of fruit juices. 16.1% of the participants were informed about the erosive potential of some medicines such as vitamin C. Nearly half of the parents (46.6%) found vigorous tooth brushing damaging.

Conclusions: Despite the high self-esteem, a low percentage of the respondents were actually aware of the most common risk factors for dental erosion in children.

Published: August 2021

Aim: To test the validity of Borg’s 6–20 rating of perceived exertion scale in assessing the exertion intensity over a multi-activity session in young and older adults.Materials and methods: This cross-sectional study included 56 healthy participants. All participants underwent a single session of activities including working on a computer, treadmill walking, biking, and treadmill running.

Results: Results showed a non-significant correlation between the overall perceived exertion and energy expenditure in young people (Rho=−0.05, p=0.75) and in older adults (Rho=−0.05, p=0.78) for the whole session. However, results showed that older adults perceived significantly higher exertion compared to young people while working on a computer, walking and running, whereas they presented lower energy expenditure while resting and working on a computer.

Conclusions: Combining the perceived exertion method with other commonly used methods to estimate exercise intensity would be recommended for older adults.
Comparison of serum levels of collagen type I turnover markers in early-onset preeclampsia and healthy pregnant women
Authors: Nikolov Asparuh G. , Popovski Nikola K. , Blazhev Alexander B. , Blazheva Svetla
Published: August 2021

Introduction: Collagen type I is a major structural component of human uterus. Recent studies have found that collagen type I turnover is altered in preeclampsia and imbalance occurs between collagen synthesis and degradation processes. This acts as a stimulus for abnormal changes in the concentrations of collagen type I derived products in circulating blood.

Aim: Having in mind the pathological collagen type I turnover in preeclampisa, the aim of the present study was to determine the levels of N-terminal propeptide of collagen type I (PINP), C-terminal propeptide of collagen type I (PICP): both markers of collagen type I synthesis and levels of matrix metalloproteinase-1 (MMP-1): marker of collagen type I degradation in sera of women with early-onset preeclampsia.

Materials and methods: Thirty-two patients with early-onset preeclampsia were examined. The mean age of the patients was 28.8±5.5 years; and the mean age of 22 age-matched healthy pregnant women was 28.5±6.0 years. The enzyme-linked immunosorbent assay (ELISA) was used for measuring serum levels of PINP, PICP and MMP-1.

Results: There were no statistically significant differences between levels of PINP, PICP and MMP-1 in the sera of women with preeclampsia and healthy pregnancies: 16.991 (15.41÷21.143) vs. 17.189 (15.805÷20.747) µg/L (KW=0.02; p>0.05), 10.929 (8.7÷13.937) vs. 11.474 (7.369÷11.932) µg/L (KW=0.026; p>0.05), and 2.097 (1.384÷2.923) vs. 2.589 (1.41÷4.533) µg/L (KW=0.238; p>0.05), respectively. There were statistically significantly higher number of patients from the preeclampsia group than healthy pregnant women with BMI≥25 (23/32 vs. 4/22) and abnormal UAD (18/32 vs. 2/22) (p<0.05).

Conclusions: Our results did not show significant differences between serum levels of PINP, PICP and MMP-1 (markers of collagen type I turnover) in women with early-onset preeclampsia and healthy pregnancy. Further studies with more specific methods and larger sample size are required to assess changes in the serum levels of PINP, PICP and MMP-1 in early-onset preeclampsia.
Periglacial landforms and the geological controlling factors: examples from the highest mountains of the Balkan Peninsula
Authors: Gachev Emil
Published: August 2021

Periglacial landforms are typical features of the high mountain environment on the Balkan Peninsula. Their formation and diversity is determined by climatic, topographic and geological factors. Presently active periglacial processes occur above 1700-2000 m a. s. l., while relict features are observed down to 1100-1400 m a. s. l. Among the most prominent periglacial landforms are the extensive talus screes and fans, the numerous rock glaciers (especially in Rila, Pirin, Shar and Prokletije Mountains) – considered mostly relict – and nivation features (nivation cirques, long-lasting snow patches), as well as cryo-clastuc landforms (stone seas and strips). The present study aims to focus on the importance of geological conditions (bedrock composition and structure, tectonic settings) for the diversity and style of periglacial landforms – a factor, whose role has often been underestimated. The analysis and the derived conclusions are based mainly on regional and local comparisons between the high mountains throughout the peninsula.
Novel lures and COI sequences reveal cryptic new species of Bactrocera fruit flies in the Solomon Islands (Diptera, Tephritidae, Dacini)
Authors: Leblanc Luc , Tsatsia Francis , Doorenweerd Camiel
Published: August 2021

Results from a snap-shot survey of Dacine fruit flies carried out on three of the Solomon Islands in April 2018 are reported. Using traps baited with the male lures cue-lure, methyl eugenol, and zingerone, 30 of the 48 species previously known to occur in the Solomon Islands were collected. Six species are newly described here: Bactrocera allodistinctasp. nov., B. geminosimulatasp. nov., B. kolombangaraesp. nov., B. quasienochrasp. nov., B. tsatsiaisp. nov., and B. vargasisp. nov., all authored by Leblanc & Doorenweerd. An illustrated key to the 54 species now known to be present in the country is provided.
Fuite des cerveaux, gain de cerveaux et politique d’éducation optimale : implications pour le bien-être des non-migrants
Authors: Schiff Maurice
Published: August 2021

Un investissement plus important dans l’éducation ( h ) est une réponse optimale ex ante à une « fuite des cerveaux » ou « brain drain » (BD) . Cependant, les gouvernements des pays d’origine doivent faire face à la situation ex post des résidents ayant un niveau d’éducation ( h) plus élevé mais qui n’ont pas migré. Bien qu’un gain net de cerveaux ou « brain gain » (BG) ait été considéré comme un avantage et appelé « fuite bénéfique des cerveaux » dans la littérature, son impact sur le bien-être des résidents du pays d’origine est au mieux ambigu. L’augmentation des investissements dans l’éducation en réponse à une BD équivaut à un pari où les migrants ( M ) gagnent et où l’impact sur les résidents ( R ) – dont le bien-être est une préoccupation pour le gouvernement – est ambigu ou négatif. Je compare le bien-être des résidents pour une économie ouverte et une économie fermée a)  en présence ou en l’absence d’une externalité de l’éducation, b ) avec ou sans intervention du gouvernement, et c ) avec une préoccupation du gouvernement égale pour R et M ( R  =  M ) ou supérieure pour R ( R  >  M ). Les principales conclusions sont les suivantes : i ) les résidents sont moins bien lotis dans une économie ouverte dans la plupart des scénarios, avec un résultat ambigu en cas d’externalité et d’absence d’intervention ; ii ) la politique d’éducation optimale en cas d’externalité a un impact positif (ambigu) sur le bien-être des résidents dans une économie fermée (ouverte) ; iii ) le bien-être des résidents est plus élevé en cas d’intervention pour R  >  M que pour R = M ; iv ) une augmentation du degré de sélectivité des compétences de la politique d’immigration réduit le bien-être des résidents. Une implication politique est que la subvention de l’enseignement supérieur, qui est optimale en cas d’externalité de l’éducation dans une économie fermée, n’est pas nécessairement valable dans le cas d’une économie ouverte.

Éthique, mystique et politique du soin : une lecture des récits de l’épidémie de typhus au camp de Dachau
Authors: Saintôt Bruno
Published: August 2021

L’article procède à une lecture des différents écrits du jésuite Jacques Sommet, qui analysent l’expérience de l’épidémie de typhus au camp de concentration de Dachau entre fin 1944 et la libération d’avril 1945. Cette lecture met en lumière les ressources et le processus de l’engagement, du discernement, de la décision et de l’action, qui conduisent à vouloir accompagner jusqu’au bout les personnes atteintes, c’est-à-dire à « vivre comme des vivants, pour aider les mourants à mourir comme des vivants ». À son tour, focalisée par la valeur universelle d’une expérience incomparable, cette mise en lumière vient éclairer nos manières actuelles de penser et d’agir en temps d’épreuve, notamment en temps de pandémie, en dégageant quelques critères pour conjuguer une éthique, une mystique et une politique du soin.
L’État qui vous veut du bien : quelques leçons à tirer de la gestion de la crise sanitaire par l’autorité publique
Authors: Greiner Dominique
Published: August 2021

Partant de l’exemple français, la contribution explore la manière dont l’État a géré la crise sanitaire. Ce retour de l’État n’est cependant pas sans ambiguïté. Les enjeux de santé publique ont pris le devant sur un certain nombre de libertés fondamentales, comme la liberté de se rassembler pour le culte. C’est aussi le principe de subsidiarité qui a été malmené, faisant courir le risque d’une dérive autoritariste y compris dans les démocraties libérales. La réflexion théologique invite à examiner de manière critique la prétention totalisante de l’État.
Linear Endotheliitis Following Posterior Chamber Phakic Intraocular Lens Implantation
Authors: Alió del Barrio Jorge L. , Alió Jorge L.
Published: August 2021

PURPOSE:

To describe a case of linear corneal endotheliitis in a healthy patient with no previous relevant ophthalmic history other than high myopia, who unilaterally developed this disease during the early postoperative period after Implantable Collamer Lens (ICL; STAAR Surgical) phakic intraocular lens (IOL) implantation.

METHODS:

Case report.

RESULTS:

An ICL was uneventfully implanted in the right eye of a 42-year-old woman. After normal examination results at 24 hours postoperatively, sudden loss of vision occurred 48 hours postoperatively due to a moderate focal stromal and epithelial edema at half of the cornea, with a sharp transition between the edematous and the healthy cornea delimited by a fine line of keratic precipitates, associated ocular hypertension, and fine anterior chamber cellular activity. Results of a polymerase chain reaction test of the aqueous humor for herpes virus were negative, but the patient reported a previous history of herpes labialis. Diagnosis of linear endotheliitis was established, and empirical treatment with oral valaciclovir, topical hypotensive drugs, and intense topical steroid was started. Complete resolution of the corneal edema and cellular activity occurred after 2 weeks of treatment. Although visual potential was fully restored, endothelial cell density decreased to less than 1,000 cells/mm
2
, and recurrent episodes of mild hypertensive iritis with difficult intraocular pressure control resulted in explantation of the ICL 2 months after surgery.

CONCLUSIONS:

This is the first case reported of linear endotheliitis after phakic IOL implantation. The observation of severe focal corneal edema after any uneventful intraocular surgery should lead to the suspicion of this rare disease, where an early diagnosis and intensive empirical treatment are essential for a successful outcome.

Un roman pour le roi : Gargantua
Authors: Milhe Poutingon Gérard
Published: August 2021

Que n’a-t-on pas dit sur Rabelais depuis le XVIe siècle ? Fut-il un « Eschyle de la mangeaille » (Victor Hugo) ou « le pourceau des moines défroqués, se délectant dans sa bauge immonde et faisant rejaillir avec délices les éclaboussures de sa lie sur le visage, sur les mœurs et sur la langue de son siècle » (Lamartine) ? Son œuvre est-elle « une énigme incompréhensible, inexplicable, une chimère, monstrueux assemblage d’un morale fine et ingénieuse et d’une sale corruption » (La Bruyère) que seules pouvaient goûter «quelques personnes d’un goût bizarre » (Voltaire), ou le fruit d’un « génie-mère » (Chateaubriand) « inventeur d’une France nouvelle » (Nodier) ? Certains le virent athée, occultiste, chantre de la liberté du peuple… Si Gargantua, roman ambigu, est capable de susciter certaines de ces lectures, il est avant tout un texte politique, pleinement inscrit dans la réalité de son temps. Il est aussi, par sa satire des traves de l’humanité, une œuvre universelle.
« Ce sont œuvres de jeunesse, ce sont coups d’essai »
Authors: Lestringant Frank
Published: August 2021

Clément Marot ou l’éternel « adolescent », comme l’indique le titre de son principal recueil, L’Adolescence clémentine, publié en 1532, alors qu’il a déjà trente-six ans et seulement une douzaine d’années à vivre. Cette œuvre, com­posée tout entière pendant le règne de François Ier, est la manifestation la plus claire, la plus évidente, de la Renaissance des lettres qui a fleuri à l’aube du XVIe siècle. Œuvre classée par genres, où les ballades et les rondeaux font bon ménage avec les épîtres et les chansons, les épitaphes et les complaintes, œuvre polyphonique souvent mise en musique, L’Adolescence clémentine s’inscrit dans le droit fil de la poésie médiévale, tout en la modernisant, la renouvelant et la transformant, dix ans avant que ne surgisse la révolution poétique de la Pléiade, laquelle ne parviendra pas à la faire oublier.
Poésie instable que celle de L’Adolescence clémentine, dialogante, effer­vescente, jamais fixée, toujours répétée, mais comme on répète un texte de théâtre, en le découvrant et en le variant à chaque reprise, poésie continuée jusqu’à La Fontaine et Voltaire, à redécouvrir de toute urgence aujourd’hui.
