Establecimiento del grado de alteración en muros de edificios históricos de San Francisco de Campeche, México, empleando análisis de imágenes y el sistema de estadificación UAS
Authors: Silva León Isabel , Reyes Trujeque Javier , Escalante Díaz Claudia
Published: June 2021

La ciudad histórica de San Francisco de Campeche (SFC), México, cuenta con un importante conjunto de edificios Barrocos, construidos con mampostería de piedra caliza, expuestos al clima tropical húmedo de la región. Estos materiales sufren alteración diferencial en función de las condiciones microclimáticas específicas de su entorno. Tradicionalmente, el diagnóstico del estado de conservación de los materiales pétreos es un procedimiento que consume considerables recursos económicos y tiempo. Sin embargo, existen alternativas a estas metodologías, que también permiten determinar el alcance de posibles intervenciones en estructuras deterioradas, como la empleada en este trabajo, que combinó el análisis de imágenes, el sistema de estadificación UAS y la caracterización mineralógica mediante MEB-EDS y FTIR para establecer estadios de alteración en muros de dos baluartes del recinto amurallado de SFC.
Aplicação e análise da ferramenta ‘índice comportamental’ na gestão de uma obra conceptual de Joseph Kosuth
Authors: Sousa Francisca
Published: June 2021

Este artigo documenta a aplicação da ferramenta de gestão de arte conceptual ‘índice comportamental’ (Stigter 2011) a One and three plants, 1965 de Joseph Kosuth. A arte contemporânea engloba diversas obras com características variáveis, frequentemente intrínsecas. A análise do ‘comportamento’ de determinada obra ao longo do tempo e das suas iterações, permite-nos construir uma perspetiva biográfica que pode auxiliar um processo de decisão mais consciente e responsável. Dado o vasto espectro de documentação gerada na instalação e conservação destas obras, urge apelar a uma abordagem de conservação que seja sistemática, simplificada e de fácil interpretação. O ‘índice comportamental’ permite abranger grandes quantidades de informação, frequentemente subjetiva, num sumário biográfico com uma importante componente visual e esquemática. A aplicação desta ferramenta a One and three plants permitiu delimitar o espectro da sua variabilidade, refletindo sobre apresentações passadas e eventuais exposições futuras numa apreciação crítica essencial para a sua preservação.

UDC 517.9
This paper deals with the problem of stability of nonlinear differential equations with perturbations. Sufficient conditions for global uniform asymptotic stability in terms of Lyapunov-like functions and integral inequality are obtained. The asymptotic behavior is studied in the sense that the trajectories converge to a small ball centered at the origin. Furthermore, an illustrative example in the plane is given to verify the effectiveness of the theoretical results.

The prevalence of cancer distress among patients diagnosed with cancer varies between 20-52%, data from recent years in our country indicating that almost half of them experience depressive or anxious symptoms throughout the course of the disease. Individualized psychosocial care should be recognized as a universal human right, and should be integrated into the patient's routine care. Screening and management of oncological distress performed by a multidisciplinary team is a necessary standard to achieve a quality patient-centered care.

Meniscus injuries are the most common traumatic conditions of the knee. If until the early 2000s, menisci were considered structures of no major importance in the knee joint, subsequent studies have shown their importance in the biomechanics of the knee. Their role is not only for the natural suspension of the joint, but also for the protection of the cartilage or the achievement of the efficient and uniform circulation of the synovial fluid. Therefore, disruption of this joint balance can lead, in the absence of a well-conducted treatment, to premature knee wear. Most of the time, these meniscal tears are accompanied by associated lessions, ligaments or more severely cartilaginous lessions, creating a real challenge for the physician, specially for young pacients. There are many conservative treatments of the damaged meniscus, imagined precisely in the idea of preserving the menisci as much as possible. However, this is not always possible, especially due to the type of traumatic injury.

Breast cancer is the most common type of cancer among women, and its early diagnosis can lead to a survival of over 90% at 5 years. In order to achieve correct education of the population, especially of young women and of the entire medical staff, we consider necessary the review of the risk factors for breast cancer and the possibilities of prophylaxis. Although the survival of breast cancer patients has improved among European Union countries over the last decade (from 79% to 83%), Romania is still at the bottom of the ranking with 75% survival at 5 years, and an assessment of the last 12 months would reveal even more worrying values.

Psoriasis is a chronic skin disease with an important inflammatory compound which associates a worldwide prevalence of 0.5% to 8.5%. The involvement of the genital region can be associated with both plaque psoriasis and inverse psoriasis and survey-based studies indicate that up to 45.5% of patients present lesions of genital psoriasis. Genital psoriasis represents a frequent encounter of psoriasis which is often overlooked and which associates a significant impact on their quality of life, measured by Dermatology Life Quality Index (DLQI) scores which are twice as high as those of psoriatic patients without genital involvement. Recognising the specific clinical findings represents an important step in establishing the diagnosis and case management. Classical therapeutic options such as topical steroids or modern treatments such as ixekizumab represent important tools in fighting this affliction and regaining the patient’s quality of life. This review aims to emphasize the up-to-date clinical variants of genital psoriasis, the consequences on the quality of life of patients and to present the newest therapeutic options.

Yirminci yüzyılın başları İtalya’da dergi yayıncılığının zirve yaptığı yıllardır. Bu dönemde çıkan Leonardo, La Voce ve Lacerba dergilerinde kültür, sanat, politika, felsefe ve edebiyat dâhil, hayatın farklı alanlarına dair makaleler yayınlanır. Floransa avangardının yayın organı olan dergilerde Birinci Dünya Savaşı’na ilişkin İtalyan devletinin politikalarına yönelik sert ve yönlendirici yazılar yayınlanır. Ayrıca 1909 yılında Marinetti’nin kurucusu olduğu Fütürizm’e dair yazılar da dergilerde geniş yer tutar. İtalya’yı kültürel olarak Avrupa seviyesine taşıyan dergiler İtalyan kültür hayatının canlanmasında önemli bir konuma sahiptirler. 1903-1916 yılları arasında yalnızca İtalyan yazarlar değil, aynı zamanda başta Fransa ve Almanya olmak üzere, pek çok Avrupa ülkesinden yazar, ressam, filozof ve şairin çeşitli konulardaki görüşleri bu üç avangart dergide ifadesini bulur. Bunlar arasında, söz konusu dergilerde yöneticilik yapan ve yazıları yayınlanan Giovanni Papini, yeni yeşeren Floransa avangart kültürünün öncülerinden biri olarak ortaya çıkmaktadır. Bu çalışmada, dergilerden alıntılar da verilerek, özellikle söz konusu dönemde Birinci Dünya Savaşı ve Fütürizm bağlamında dergilerin yayın politikaları ile bu politikaların İtalyan kültürüne etkileri üzerinde durulacaktır.
Local intermittency measure analysis of neutron monitor data
Authors: MacKinnon Alexander , Rennie Sam
Published: June 2021

Local Intermittency Measure (LIM) is a development of wavelet analysis particularly suited to the diagnosis of isolated, intermittent events in time series. We construct LIM scalograms
of Neutron Monitor (NM) data for an example each of a large GLE and a Forbush decrease. Both kinds of event show distinctive LIM signatures. In the case of the Forbush decrease the
method also identifies a second, much smaller event that took place in the same time period. LIM may thus be a useful tool for automated or semi-automated detection of such events in NM data.

En este ensayo se pretende problematizar la brecha entre el ideal cristiano y lo realmente logrado por la Iglesia a partir de la actividad catequística tradicional, una brecha evidente que causa fuerte desazón entre los jóvenes en particular.

La pregunta que se plantea es qué catequesis es necesaria para iluminar la mirada social de los cristianos. Se llega así, a la propuesta de una catequesis lejana al modelo tradicional, con demasiada frecuencia centrada en la obtención de un sacramento, casi de espaldas a la vida concreta de las personas; en especial, poco sensible al compromiso sociopolítico que brota del Evangelio.

Esta propuesta implica cierto número de consecuencias para los modos tradicionales en que se organiza la catequesis a nivel local, y en el modo en que se diseñan los itinerarios formativos.

In line with the development and demands of human culture, parents cannot meet the needs of their children's educators. For that they submit their child's education to others. People who accept the mandate of parents to educate children are called teachers. The teaching profession is a noble profession because in addition to studying one's knowledge, it also demands that someone have noble morals.It seems that the most important factors in the teaching profession today are only scientific and academic qualifications. Meanwhile, other factors such as wisdom and wisdom which are moral attitudes and behaviors are no longer essential. As a result, the moral exemplary of the teachers is no longer so important in the educational process, what is more important is the skills and expertise in teaching science which is their duty.Therefore, everyone who will carry out teacher duties must have a personality that is in accordance with Islamic teachings and is even more required to have a teacher personality. Personality is the most important factor for a teacher.
GISIMOS MCDA LAND SUITABILITY MODEL FOR ECOTOURISM DEVELOPMENT
Authors: Aşilioğlu Fatma
Published: June 2021

Ecotourism development planning is a multi-criteria process that generally requires spatial analysis. GISimos MCDA model developed by this study, was presented for the first time and applied to the Kalecik sub-province of Ankara, Turkey to determine the suitable areas and their suitability levels for ecotourism development. The model is based on the evaluation of sub-factors representing the topography, land cover, climate and sociocultural characteristics of the region, with the combination of GIS and the revised Simos procedure, one of the MCDA techniques. It included a series of processes such as determining the suitability rates and weights of sub-factors, calculating the Ecotourism Suitability Index values, and overlapping them using the WLC method. The resulting values were categorized as highly suitable, moderately suitable, marginally suitable, and not suitable areas. The results of this study and the method developed will be helpful for decision-makers and planners in the study area and similar regions.
Living with Neighbors. IV. Dissecting the Spin–Orbit Alignment of Dark Matter Halos: Interacting Neighbors and the Local Large-scale Structure
Authors: An Sung-Ho , Kim Juhan , Moon Jun-Sung , Yoon Suk-Jin
Published: June 2021

Spin–orbit alignment (SOA; i.e., the vector alignment between the halo spin and the orbital angular momentum of neighboring halos) provides an important clue to how galactic angular momenta develop. For this study, we extract virial-radius-wise contact halo pairs with mass ratios between 1/10 and 10 from a set of cosmological N-body simulations. In the spin–orbit angle distribution, we find a significant SOA in that 52.7% ± 0.2% of neighbors are on the prograde orbit. The SOA of our sample is mainly driven by low-mass target halos (<1011.5
h
−1
M
⊙) with close merging neighbors, corroborating the notion that tidal interaction is one of the physical origins of SOA. We also examine the correlation of SOA with the adjacent filament and find that halos closer to the filament show stronger SOA. Most interestingly, we discover for the first time that halos with the spin parallel to the filament experience most frequently prograde polar-interaction (i.e., fairly perpendicular but still prograde interaction; spin–orbit angle ∼70°). This instantly invokes the spin-flip event and the prograde-polar interaction will soon flip the spin of the halo to align it with the neighbor’s orbital angular momentum. We propose that SOA originates from the local cosmic flow along the anisotropic large-scale structure, especially that along the filament, and grows further by interactions with neighbors.
Compressive Oscillations in Hot Coronal Loops: Are Sloshing Oscillations and Standing Slow Waves Independent?
Authors: Prasad S. Krishna , Van Doorsselaere T.
Published: June 2021

Employing high-resolution EUV imaging observations from SDO/AIA, we analyze a compressive plasma oscillation in a hot coronal loop triggered by a C-class flare near one of its footpoints, as first studied by Kumar et al. We investigate the oscillation properties in both the 131 Å and 94 Å channels and find that what appears as a pure sloshing oscillation in the 131 Å channel actually transforms into a standing wave in the 94 Å channel at a later time. This is the first clear evidence of such transformation and confirms the results of a recent numerical study that suggests that these two oscillations are not independent phenomena. We introduce a new analytical expression to properly fit the sloshing phase of an oscillation and extract the oscillation properties. For the AIA 131 Å channel, the obtained oscillation period and damping time are 608 ± 4 s and 431 ± 20 s, respectively, during the sloshing phase. The corresponding values for the AIA 94 Å channel are 617 ± 3 s and 828 ± 50 s. During the standing phase that is observed only in the AIA 94 Å channel, the oscillation period and damping time have increased to 791 ± 5 s and 1598 ± 138 s, respectively. The plasma temperature obtained from the differential emission measure analysis indicates substantial cooling of the plasma during the oscillation. Considering this, we show that the observed oscillation properties and the associated changes are compatible with damping due to thermal conduction. We further demonstrate that the absence of a standing phase in the 131 Å channel is a consequence of cooling plasma besides the faster decay of oscillation in this channel.
The Evolution of the Ultraluminous Lyα Luminosity Function over z = 5.7–6.6

Published: June 2021

Ultraluminous Lyα emitting galaxies (ULLAEs) with

erg s−1 near the epoch of reionization (z > 5) make up the bright end of the LAE luminosity function (LF) and may provide insight into the process of reionization, including the formation of ionized bubbles around these extreme systems. We present a spectroscopic LF for ULLAEs at z = 5.7. We used data from the HEROES ∼45 deg2 Subaru Hyper Suprime-Cam survey, which is centered on the North Ecliptic Pole and has both broadband (grizY) and narrowband (NB816 and NB921) imaging, to select candidate ULLAEs based on a NB816 excess and a strong broadband Lyman break. We spectroscopically observed 17 ULLAE candidates with DEIMOS on Keck II. We confirmed 12 as LAEs at z = 5.7, 9 of which are ULLAEs. The remaining sources are an active galactic nuclei at z = 5.7, an [O III]λ5007 emitter at z = 0.63, a red star, and two spectroscopic nondetections. Using the nine confirmed ULLAEs, we construct a ULLAE LF at z = 5.7. After applying a comprehensive incompleteness correction, we compare our new z = 5.7 LF with our recent z = 6.6 LF and with other LFs from the literature to look for evolution at the ultraluminous end. We find the overall ratio of the z = 5.7 to z = 6.6 ULLAE comoving number densities to be

, which corresponds to an LF offset of

A small number of anomalously bright boulders on the near-Earth rubble-pile asteroid (101955) Bennu were recently identified as eucritic material originating from asteroid (4) Vesta. Building on this discovery, we explored the global presence of exogenic boulders on Bennu. Our analysis focused on boulders larger than 1 m that show the characteristic 1 μm pyroxene absorption band in the four-color MapCam data from the OSIRIS-REx mission. We confirm the presence of exogenic boulders similar to eucrites and find that a mixture of eucrite with carbonaceous material is also a possible composition for some boulders. Some of the exogenic boulders have spectral properties similar to those of ordinary chondrite (OC) meteorites, although the laboratory spectra of these meteorites have a higher albedo than those measured on Bennu, which could be explained by either a grain size effect, the presence of impact melt, or optical mixing with carbonaceous material owing to dust coating. Our Monte Carlo simulations predict that the median amount of OC mass added to the parent body of Bennu is 0.055% and 0.037% of the volume of a 100 and 200 km diameter parent body, respectively. If Bennu was a uniformly mixed by-product of parent body and S-type projectiles, the equivalent mass of OC material would be a sphere with a diameter of 36–40 m (or a volume of 24,200–33,600 m3). The total amount of OC material in the interior of Bennu estimated from the MapCam data is slightly higher (91,000–150,000 m3).

Published: June 2021

Seagrass habitats are considered to be some of the most biodiverse ecosystems on the planet and safeguard some ecologically and economically important fauna, amongst which are some globally threatened species, including dugong. Malaysian seagrass ecosystems are not widespread, but their existence supports some significant marine fauna. A rigorous zooplankton study was conducted from May 2016 to February 2017, in the seagrass habitat of Lawas, Sarawak, Malaysia, to examine their temporal composition and diversity, together with their ecological influences. A total of 45 zooplankton species from 13 significant groups were recorded in the seagrass habitat. The population density of zooplankton ranged between 2,482 ind/m³ and 22,670 ind/m³ over three different seasons. A single zooplankton copepod was found to be dominant (47.40%), while bivalves were the second largest (31.8%) group in terms of total abundance. It was also noticed that the average relative abundance (0.62) and important species index (62.08) of copepods were higher than for other groups that exist in the seagrass meadow, whereas copepod Parvocalanus crassirostris showed both the highest average relative abundance (0.41) and the highest important species index (41.15). The diversity (H') and richness index of the intermediate season were found to be highest due to favourable physico-chemical conditions. Within the referred seasonal cluster, the wet and dry seasons were almost similar in terms of species abundance, while the intermediate season was distinct, with high species diversity backed by ANOSIM analysis results. Copepod and bivalves formed one group with a common similarity level of 0.80. The CCA (Canonical Correspondence Analysis) model established that abiotic factors, especially turbidity, NO2, rainfall, dissolved oxygen and pH were significantly correlated with abundance of individual groups of zooplankton. Zooplankton assemblage and abundance in Lawas were found to be very rich in multiple seasons, indicating that the productivity of uninterrupted seagrass habitat might be high and the system rich in biodiversity.
Factors influencing acceptance or rejection by Iranian medical researchers of invitations to peer review
Authors: Talei Maryam , Handjani Farhad , Astaneh Behrooz , Askarian Mehrdad , Jafari Peyman
Published: June 2021

Background: Peer review is a necessary but costly and time-consuming process to identify good-quality and methodologically sound articles and improve them before publication. Finding good peer reviewers is often difficult.

Objective: To identify the incentives that make Iranian biomedical researchers accept invitations to be a peer reviewer and factors that affect these incentives.

Methods: Twelve reviewers selected at random from the reviewers pool of each of 26 biomedical journals published from Fars province, Iran, were surveyed using a questionnaire that we had developed and tested in a pilot study of 30 reviewers (Cronbach’s alpha of 0.779). The data included the reviewers’ demographics, history of their reviews, and choice of 11 reasons each for accepting or declining the invitation to review.

Results: A total of 233 reviewers completed the questionnaire. The most important reasons for accepting the invitation to review were the journal’s practice to publish the names of the reviewers alongside the article they had reviewed, acknowledgement by the journals by publishing the names of reviewers once a year, free access to journals’ content, and lower publication charges as authors. The most common reasons to decline the invitation were lack of time, busy schedules, and lack of sufficient incentive to review.

Conclusion: Acknowledgement by the journal, offering to publish the names of reviewers alongside the articles they had reviewed, and monetary rewards will be effective incentives for biomedical researchers in Iran to serve as peer reviewers.
On the recognition of the long neglected Vitis adenoclada Hand.-Mazz. (Vitaceae) from southern China
Authors: Wen Jun , Ma Zhi-Yao
Published: June 2021

This study reports the recognition of Vitis adenoclada Hand.-Mazz. from southern China. The species was not recognized in the Flora Reipublicae Ropularis Sinicicae and Flora of China treatments. Recent field studies and examination of herbarium collections including the type material suggest that Vitis adenoclada is morphologically similar to V. heyneana, in their densely arachnoid tomentose abaxial leaves, yet it can be easily distinguished from the latter by its red-purple glandular hairs on the young branches (vs. glandular hairs absent in V. heyneana) and inflorescences usually subtended by a tendril at the base (vs. only occasionally with a tendril in V. heyneana). Vitis adenoclada may be a species of hybrid origin, with the highly tomentose Vitis heyneana as one of the parental species, and likely the glandular-hair bearing V. davidii as the other parental species. Vitis adenoclada is recorded from southern China in Guangdong, Guangxi, Guizhou, Hunan and Zhejiang provinces.

Background/Aims: Annual fecal immunochemical tests (FITs) are often repeated within the recommended colonoscopy surveillance intervals. However, it remains unclear whether interval FITs are useful. To answer this question, we assessed the risk of colorectal cancer (CRC) according to the interval from the last colonoscopy to an FIT.Methods: Using the Korean National Cancer Screening Program database, we collected data on patients who underwent FITs in 2011. Patients with positive FIT results were classified into three groups according to their previous colonoscopy interval: 0.5 to 5 years (group 1), 5 to 10 years (group 2), and ≥ 10 years or no colonoscopy (group 3). CRC incidence was defined as CRC diagnosed within 1 year after an FIT.Results: Among 177,660 patients with positive FIT results, the incidence of CRC in groups 1, 2, and 3 was 0.72% (n = 214/29,575), 1.28% (n = 116/9,083), and 3.88% (n = 5,387/139,002), respectively. The age- and sex-adjusted risk for CRC was higher in groups 2 (odds ratio [OR], 1.79; 95% confidence interval [CI], 1.43 to 2.25) and 3 (OR, 5.56; 95% CI, 4.85 to 6.38) than in group 1. Among patients who did and did not undergo a polypectomy during the previous colonoscopy, those in group 2 had a higher rate of CRC than those in group 1 (without polypectomy: 1.15% vs. 0.63%; OR, 1.79; 95% CI, 1.37 to 2.34) (with polypectomy: 2.37% vs. 0.93 %; OR, 2.30; 95% CI, 1.44 to 3.69).Conclusion: In patients with positive FIT results who had undergone a colonoscopy within the past 5 years, the risk of CRC is very low, regardless of whether a polypectomy was performed, suggesting that interval FITs are not useful.
Pertes et deuil des acteurs de la digitalisation : le cas de l’automatisation des caisses dans la grande distribution suisse
Authors: Audrin Bertrand , Davoine Eric , Métraux Jean-Claude
Published: June 2021

Cette étude mobilise le cadre conceptuel du deuil et des pertes pour comprendre les réactions des acteurs organisationnels dans un contexte de changement digital. La recherche empirique se base sur une double étude de cas auprès des deux leaders du marché de la grande distribution suisse ayant mis en œuvre des systèmes d’encaissement automatique (technologies en libre-service), avec un corpus de 8 entretiens avec des managers, 12 entretiens avec des caissières et 75 entretiens avec des clients. L’étude permet d’identifier différents types de pertes perçues par les trois groupes d’acteurs concernés par la digitalisation. Alors que les managers vont surtout concevoir le changement numérique avec une perspective de gains de productivité, les employé.e.s et les client.e.s expriment des pertes symboliques susceptibles de déclencher des processus de deuil : des pertes d’identité et de repères professionnels, des pertes de relation et de qualité d’interaction, ainsi que des pertes de sens liées au changement d’image ‘modernisée’ et ‘rationnalisée’ des coopératives de la distribution suisse et de la qualité de lien associée à l’échange commercial. Cette perspective permet une meilleure compréhension de ce que signifie le changement numérique pour différentes catégories d’acteurs. En intégrant les clients à titre d’« employés partiels », nous identifions les enjeux spécifiques de cette catégorie d’acteurs dans le changement digital. Sur la base de notre analyse, nous pouvons recommander d’intégrer plus systématiquement des parties prenantes comme les clients dans les processus de sensemaking du changement digital.
Le bien-être au travail conçu et ressenti par les salariés japonais. Convergences et divergences avec les salariés français et américains
Authors: Szymkowiak Sophie , Creusier Jordan
Published: June 2021

La controverse au sujet de l’universalité du bien-être au travail est à l’origine de cette étude. Tant qu’elle n’est pas assurée, la validité externe des pratiques managériales recommandées pour la main d’œuvre occidentale est sujette à caution. Nous cherchons plus précisément à savoir si la conception générale, mais aussi la manière dont les salariés japonais ressentent le bien-être au travail, sont différentes de celles de leurs homologues occidentaux. Le cas des salariés japonais est pour ce faire comparé à celui des salariés américains et français. L’hypothèse générale est que la conception du bien-être au travail est similaire en orient et en occident tandis que son ressenti – exprimé par les combinaisons originales de ses dimensions constitutives – est contingent. Pour la tester, une approche statistique centrée sur les variables puis sur les personnes est réalisée. Les résultats obtenus auprès de 612 salariés japonais tendent à conforter notre hypothèse. Si les dimensions constitutives du bien-être au travail sont similaires à celles observées en occident, certains regroupements de salariés opérés en fonction de la manière dont ils combinent ces dimensions sont en revanche spécifiques. Ces profils originaux sont ceux dominés par a) la compatibilité des différents temps sociaux, b) par la qualité des relations aux collègues et au manager, et enfin, c) par des rapports favorables aux temps sociaux et à l’environnement matériel de travail. Ainsi, les pratiques managériales préconisées pour développer toutes les dimensions du bien-être du personnel occidental pourraient ne pas être efficaces dans les établissements employant un personnel japonais.
Well-posedness of the two-phase flow problem in incompressible MHD
Authors: Li Changyan , Li Hui
Published: June 2021

In this paper, we study the two phase flow problem in the ideal incompressible magnetohydrodynamics. We propose a Syrovatskij type stability condition, and prove the local well-posedness of the two phase flow problem with initial data satisfies such condition. This result shows that the magnetic field has a stabilizing effect on Kelvin-Helmholtz instability even the fluids on each side of the free interface have different densities.
Period tripling and quintupling renormalizations below $ C^2 $ space
Authors: Kumar Rohit , Chandramouli V.V.M.S.
Published: June 2021

In this paper, we explore the period tripling and period quintupling renormalizations below \begin{document}$ C^2 $\end{document} class of unimodal maps. We show that for a given proper scaling data there exists a renormalization fixed point on the space of piece-wise affine maps which are infinitely renormalizable. Furthermore, we show that this renormalization fixed point is extended to a \begin{document}$ C^{1+Lip} $\end{document} unimodal map, considering the period tripling and period quintupling combinatorics. Moreover, we show that there exists a continuum of fixed points of renormalizations by considering a small variation on the scaling data. Finally, this leads to the fact that the tripling and quintupling renormalizations acting on the space of \begin{document}$ C^{1+Lip} $\end{document} unimodal maps have unbounded topological entropy.
Condiciones del entorno laboral informal y sus implicaciones en el riesgo de depresión para personas mayores en Ciudad Juárez, México
Authors: Sánchez-González Diego , Medrano-Ramos Magdalena , Rodríguez-Rodríguez Vicente
Published: June 2021

En América Latina muchas personas mayores trabajan en empleos informales; sin embargo, existe un limitado conocimiento sobre cómo sus condiciones laborales (horas de trabajo, ambiente, seguridad) influyen en su salud física y metal, y su calidad de vida. El objetivo de esta investigación es analizar las implicaciones del ambiente laboral en el riesgo de síntomas depresivos en personas mayores con empleos informales en Ciudad Juárez, México. La metodología analiza los datos de una encuesta intencional a trabajadores informales de 65 y más años, utilizando técnicas cuantitativas (intervalos de confianza, correlaciones, chi-cuadrado, Odds Ratio, regresión logística binaria, ANOVA y Post Hoc). Los resultados indican que el riesgo de depresión está asociado con las condiciones socioeconómicas, capacidades funcionales y de salud, hábitos de consumo, y demandas del entorno laboral físico y social. Este riesgo varía según el lugar de trabajo, especialmente en comercios ambulantes y vía pública, donde también está relacionado con problemas de salud, económicos y consumo de alcohol. Se propone revisar los programas de salud pública y empleo para prevenir amenazas para la salud e integridad de personas mayores con empleos informales.
Transformaciones territoriales de las áreas costeras: análisis de la Costa Malagueña en la segunda mitad del siglo XX
Authors: Luque Revuelto Ricardo Manuel
Published: June 2021

El estudio de la Costa Malagueña es imprescindible para entender las profundas transformaciones territoriales que ha sufrido las áreas costeras españolas en la segunda mitad del siglo XX. Los libros de Derrotero son un instrumento imprescindible para la navegación litoral, pero a la vez constituyen un testigo extraordinario de estas transformaciones recientes. El Derrotero aporta una nueva perspectiva al estudio de dichas áreas, pues supone un punto de vista diferente al satelital o a la imagen cartográfica, una nueva perspectiva dada por la visión horizontal de la línea de costa que dibujan. Se exponen las características y la evolución de los Derroteros que comprenden la Costa Malagueña y se plantea como objetivo fundamental el de determinar, desde un punto de vista geográfico, su validez para el estudio de los espacios costeros y su evolución.

Published: June 2021

Owing to the adverse impact of the architecture, engineering and construction industry on the human and natural environment, the adoption of green building (GB) has been on the rise globally. The significant rise in the number of global research output on GB is a pointer to its proliferation. In this paper, a novel scientometric analysis of GB research in Africa is presented. This study aims to analyze and visualize GB research output in Africa from the millennium development goals (MDGs) era up to the present sustainable development goals (SDGs) era. A quantitative method (science mapping) was employed to analyze the 156 bibliometric records gathered from the Scopus database. An analysis of the dataset reveals that significant contributions to GB research in Africa originate from Egypt, South Africa, Nigeria, Algeria, Ghana, Morocco, Kenya, Mauritius, Ethiopia and Cameroon. This research provides stakeholders in the built environment with the requisite knowledge and understanding of the trend and state of GB research in Africa, which will help in guiding policymaking, research directions and intervention areas in every sector of the economy.

Published: June 2021

Face à la congestion croissante et les impacts négatifs sur la santé, l’environnement et les espaces publics du « tout à la voiture », la marche gagne depuis quelques années de l’importance dans les débats et les esprits. Afin de promouvoir la pratique à Bruxelles, Bruxelles Mobilité a réalisé un diagnostic des espaces publics, à travers les plans d’accessibilité de la voirie et de l’espace public [PAVE]. La recherche dont est tirée le présent article complète ce diagnostic en identifiant le spectre large des gênes au déplacement piéton et les variations de leur appréhension. Pour ce faire, plusieurs méthodologies distinctes ont été combinées (analyse spatiale et morphologique, analyse des flux et comportements piétons, parcours commentés auprès de personnes à mobilité réduite), permettant ainsi d’élaborer une vision dynamique du déplacement piéton et des gênes qui peuvent l’affecter. Sur cette base, plusieurs pistes de solution sont formulées pour arriver à un équilibre entre besoins de fluidité de déplacement, ralentissements des flux piétons et expérience de la marche.
