El viaje dionisíaco de Rosalía
Authors: Ludington Zachary Rockwell
Published: February 2024

Resumen: Este ensayo analiza la canción y el videoclip de "Aunque es de noche" (2017) como un punto de inflexión en la trayectoria artística de Rosalía. El concepto de lo dionisíaco, desarrollado a lo largo de la obra de Friedrich Nietzsche, ofrece un modelo de interpretación de las distintas fases de la carrera de la cantante, sintetizadas en esta adaptación del poema de San Juan de la Cruz. Además de una progresión en línea con las tres vías de la experiencia mística que estructuran el texto de San Juan—la purgativa, la iluminativa y la unitiva— "Aunque es de noche" puede leerse como una alegoría de la apoteosis de Rosalía, su desarrollo de una actitud heroica, capitalista, conquistadora, en fin, "apolínea", tras sus comienzos orgánicos y extáticos o, en términos nietzscheanos, propiamente "dionisíacos".

Published: February 2024

Laser-induced subwavelength nanogratings on films find widespread applications in enhancing a spectrum through surface plasmon excitation. It is challenging to achieve high uniformity, diversity, and controllability due to the intricate interplay between two basic mechanisms in laser nanostructuring: the Marangoni effect and surface plasmon polaritons (SPPs). We tune the coupled effect on Ge2Sb2Te5 films by adjusting the laser polarization, whose component controls the two effects’ strength ratio. The Marangoni effect dominates when the SPPs’ direction mismatches with the growing direction of nanogratings. Tuning this competition relationship helps to create nanogratings with tunable duty cycle and distribution, which are significant for light modulation applications. A highly efficient direct writing method with a line-shaped laser beam is employed to create large-area regular nanogratings by enhancing the effect tuning. We demonstrate diverse Au nanogratings with the aid of a lift-off operation and apply them in surface plasmon-coupled emission (SPCE), showcasing exceptional enhancement and narrowing performance.

Telomere length (TL) is an important biomarker of cellular aging, yet its links with health outcomes may be complicated by use of different tissues. We evaluated within- and between-individual variability in TL and quality metrics of DNA across five tissues using a cross-sectional dataset ranging from 8 to 70 years (N = 197). DNA was extracted from all tissue cells using the Gentra Puregene DNA Extraction Kit. Absolute TL (aTL) in kilobase pairs was measured in buccal epithelial cells, saliva, dried blood spots (DBS), buffy coat, and peripheral blood mononuclear cells (PBMCs) using qPCR. aTL significantly shortened with age for all tissues except saliva and buffy coat, although buffy coat was available for a restricted age range (8 to 15 years). aTL did not significantly differ across blood-based tissues (DBS, buffy coat, PBMC), which had significantly longer aTL than buccal cells and saliva. Additionally, aTL was significantly correlated for the majority of tissue pairs, with partial Spearman’s correlations controlling for age and sex ranging from ⍴ = 0.18 to 0.51. We also measured quality metrics of DNA including integrity, purity, and quantity of extracted DNA from all tissues and explored whether controlling for DNA metrics improved predictions of aTL. We found significant tissue variation: DNA from blood-based tissues had high DNA integrity, more acceptable A260/280 and A260/230 values, and greater extracted DNA concentrations compared to buccal cells and saliva. Longer aTL was associated with lower DNA integrity, higher extracted DNA concentrations, and higher A260/230, particularly for saliva. Model comparisons suggested that incorporation of quality DNA metrics improves models of TL, although relevant metrics vary by tissue. These findings highlight the merits of using blood-based tissues and suggest that incorporation of quality DNA metrics as control variables in population-based studies can improve TL predictions, especially for more variable tissues like buccal and saliva.

Published: February 2024

Approximate Bayesian Computation (ABC) is a widely applicable and popular approach to estimating unknown parameters of mechanistic models. As ABC analyses are computationally expensive, parallelization on high-performance infrastructure is often necessary. However, the existing parallelization strategies leave computing resources unused at times and thus do not optimally leverage them yet. We present look-ahead scheduling, a wall-time minimizing parallelization strategy for ABC Sequential Monte Carlo algorithms, which avoids idle times of computing units by preemptive sampling of subsequent generations. This allows to utilize all available resources. The strategy can be integrated with e.g. adaptive distance function and summary statistic selection schemes, which is essential in practice. Our key contribution is the theoretical assessment of the strategy of preemptive sampling and the proof of unbiasedness. Complementary, we provide an implementation and evaluate the strategy on different problems and numbers of parallel cores, showing speed-ups of typically 10-20% and up to 50% compared to the best established approach, with some variability. Thus, the proposed strategy allows to improve the cost and run-time efficiency of ABC methods on high-performance infrastructure.

This study highlights the effectiveness of oyster shell biocomposite for the biosorption of Cd(II) and Pb(II) ions from an aqueous solution. The aim of this work was to modify a novel biocomposite derived from oyster shell for the adsorption of Cd(II) and Pb(II) ions from aqueous solution. The studied revealed the specific surface BET surface area was 9.1476 m2/g. The elemental dispersive x-ray analysis (EDS) indicated that C, O, Ag, Ca were the predominant elements on the surface of the biocomposite after which metals ions of Cd and Pb were noticed after adsorption. The Fourier transform Irradiation (FT-IR) revealed the presence of carboxyl and hydroxyl groups on the surface. The effect of process variables on the adsorption capacity of the modified biocomposite was examined using the central composite design (CCD) of the response surface methodology (RSM). The process variables which include pH, adsorbent dose, the initial concentration and temperature were the most effective parameters influencing the uptake capacity. The optimal process conditions of these parameters were found to be pH, 5.57, adsorbent dose, 2.53 g/L, initial concentration, 46.76 mg/L and temperature 28.48°C for the biosorption of Cd(II) and Pb(II) ions from aqueous solution at a desirability coefficient of 1. The analysis of variance (ANOVA) revealed a high coefficient of determination (R2 > 0.91) and low probability coefficients for the responses (P < 0.05) which indicated the validity and aptness of the model for the biosorption of the metal ions. Experimental isotherm data fitted better to the Langmuir model and the kinetic data fitted better to the pseudo-second-order model. Maximun Cd(II) and Pb(II) adsorption capacities of the oyster shell biocomposite were 97.54 and 78.99 mg/g respectively and was obtained at pH 5.56 and 28.48°C. This investigation has provided the possibility of the utilization of alternative biocomposite as a sustainable approach for the biosorption of heavy metal ions from the wastewater stream.
Misophonia is related to stress but not directly with traumatic stress

Published: February 2024

The relationship between misophonia, stress, and traumatic stress has not been well characterized scientifically. This study aimed to explore the relationships among misophonia, stress, lifetime traumatic events, and traumatic stress. A community sample of adults with self-reported misophonia (N = 143) completed structured diagnostic interviews and psychometrically validated self-report measures. Significant positive correlations were observed among perceived stress, traumatic stress, and misophonia severity. However, multivariate analyses revealed that perceived stress significantly predicted misophonia severity, over and above traumatic stress symptoms. The number of adverse life events was not associated with misophonia severity. Among symptom clusters of post-traumatic stress disorder, only hyperarousal was associated with misophonia severity. These findings suggest that transdiagnostic processes related to stress, such as perceived stress and hyperarousal, may be important phenotypic features and possible treatment targets for adults with misophonia.

Social contact mixing patterns are critical to model the transmission of communicable diseases, and have been employed to model disease outbreaks including COVID-19. Nonetheless, there is a paucity of studies on contact mixing in low and middle-income countries such as India. Furthermore, mathematical models of disease outbreaks do not account for the temporal nature of social contacts. We conducted a longitudinal study of social contacts in rural north India across three seasons and analysed the temporal differences in contact patterns. A contact diary survey was performed across three seasons from October 2015–16, in which participants were queried on the number, duration, and characteristics of contacts that occurred on the previous day. A total of 8,421 responses from 3,052 respondents (49% females) recorded characteristics of 180,073 contacts. Respondents reported a significantly higher number and duration of contacts in the winter, followed by the summer and the monsoon season (Nemenyi post-hoc, p<0.001). Participants aged 0–9 years and 10–19 years of age reported the highest median number of contacts (16 (IQR 12–21), 17 (IQR 13–24) respectively) and were found to have the highest node centrality in the social network of the region (pageranks = 0.20, 0.17). A large proportion (>80%) of contacts that were reported in schools or on public transport involved physical contact. To the best of our knowledge, our study is the first from India to show that contact mixing patterns vary by the time of the year and provides useful implications for pandemic control. We compared the differences in the number, duration and location of contacts by age-group and gender, and studied the impact of the season, age-group, employment and day of the week on the number and duration of contacts using multivariate negative binomial regression. We created a social network to further understand the age and gender-specific contact patterns, and used the contact matrices in each season to parameterise a nine-compartment agent-based model for simulating a COVID-19 epidemic in each season. Our results can be used to parameterize more accurate mathematical models for prediction of epidemiological trends of infections in rural India.
A biodynamic model predicting copper and cadmium bioaccumulation in caddisflies: Linkages between field studies and laboratory exposures
Authors: Hornberger Michelle I.
Published: February 2024

Hydropsyche and Arctopsyche are filter-feeding caddisflies (Order: Trichoptera; Family: Hydropsychidae) that are commonly used to monitor metal exposures in rivers. While tissue residue concentrations provide important bioaccumulation data regarding metal bioavailability, they do not provide information regarding the mechanisms of uptake and loss, or exposure history. This study examined the physiological processes that control Cu and Cd uptake and loss using a biokinetic bioaccumulation model. Larvae of each taxon were experimentally exposed to either water or food enriched with stable isotopes (65Cu and 106Cd). Dissolved Cu uptake (ku) was similar between species (2.6–3.4 L-1g 1d-1), but Cd uptake was 3-fold higher in Hydropsyche than Arctopsyche (1.85 L-1g 1d-1 and 0.60 L-1g 1d-1, respectively). Cu and Cd efflux rates (ke) were relatively fast (0.14 d-1–0.24 d-1) in both species, and may explain, in part, their metal tolerance to mine-impacted rivers. Food ingestion rates (IR), assimilation efficiency (AE) of 65Cu and 106Cd from laboratory diets were also derived and used in a biodynamic model to quantify the relative contribution of dissolved and dietary exposure routes. Results from the biodynamic model were compared to tissue concentrations observed in a long-term field study and indicated that because dissolved Cu and Cd exposures accounted for less than 20% of body concentrations of either taxon, dietary exposure was the predominant metal pathway. An estimation of exposure history was determined using the model to predict steady state concentrations. Under constant exposure conditions (dissolved plus diet), steady state concentrations were reached in less than 30 days, an outcome largely influenced by rapid efflux (ke).
Empirical Bayes factors for common hypothesis tests
Authors: Dudbridge Frank
Published: February 2024

Bayes factors for composite hypotheses have difficulty in encoding vague prior knowledge, as improper priors cannot be used and objective priors may be subjectively unreasonable. To address these issues I revisit the posterior Bayes factor, in which the posterior distribution from the data at hand is re-used in the Bayes factor for the same data. I argue that this is biased when calibrated against proper Bayes factors, but propose adjustments to allow interpretation on the same scale. In the important case of a regular normal model, the bias in log scale is half the number of parameters. The resulting empirical Bayes factor is closely related to the widely applicable information criterion. I develop test-based empirical Bayes factors for several standard tests and propose an extension to multiple testing closely related to the optimal discovery procedure. When only aP-value is available, an approximate empirical Bayes factor is 10p. I propose interpreting the strength of Bayes factors on a logarithmic scale with base 3.73, reflecting the sharpest distinction between weaker and stronger belief. This provides an objective framework for interpreting statistical evidence, and realises a Bayesian/frequentist compromise.

Filial piety is viewed as strong family support for older Chinese people, and strongly associated with depressive symptoms. It is unknown if there exists gender difference in the mediation effects of filial piety on the relationship between chronic obstructive pulmonary disease (manifested as lung function) and depression. We investigated whether filial piety mediates the association between lung function and depression in community-dwelling older men and women using the Healthy Aging Longitudinal Study in Taiwan (HALST). Community dwelling adults aged 65 and above were analyzed. Pulmonary function, depressive symptoms, and filial piety expectation (FPE) and receipt of filial piety (RFP) were collected. The interaction and mediation of filial piety between lung function and depression was analyzed. We found that in older men, forced expiratory volume in the first second (FEV1) was inversely correlated with depression (β = -0.1281, p = 0.004) with no mediation effect of FPE. In older women, FEV1 was negatively associated with FPE, but FPE did not increase the risk of depression (β = 0.0605, p = 0.12). In both older men and women, FEV1 was negatively associated with RFP, while RFP reduced the risk of depression (p< 0.001). In older women, the correlation between FEV1 was complete mediation of RFP. Results indicate that feelings of insufficient filial piety may increase the likelihood of depression, especially in elderly women with worse lung function. Although modest, the main mediation effect of filial piety was improvement of lung function in older subjects, which might decrease depression.

Published: February 2024

The effects of jaw clenching on balance has been shown under static steady-state conditions but the effects on dynamic steady-state balance have not yet been investigated. On this basis, the research questions were: 1) if jaw clenching improves dynamic steady-state balance; 2) if the effects persist when the jaw clenching task loses its novelty and the increased attention associated with it; 3) if the improved dynamic steady-state balance performance is associated with decreased muscle activity. A total of 48 physically active healthy adults were assigned to three groups differing in intervention (Jaw clenching and balance training (JBT), only balance training (OBT) or the no-training control group (CON)) and attending two measurement points separated by two weeks. A stabilometer was used to assess the dynamic steady-state balance performance in a jaw clenching and non-clenching condition. Dynamic steady-state balance performance was measured by the time at equilibrium (TAE). The activities of tibialis anterior (TA), gastrocnemius medialis (GM), rectus femoris (RF), biceps femoris (BF) and masseter (MA) muscles were recorded by a wireless EMG system. Integrated EMG (iEMG) was calculated to quantify the muscle activities. All groups had better dynamic steady-state balance performance in the jaw clenching condition than non-clenching at T1, and the positive effects persisted at T2 even though the jaw clenching task lost its novelty and attention associated with it after balance training with simultaneous jaw clenching. Independent of the intervention, all groups had better dynamic steady-state balance performances at T2. Moreover, reductions in muscle activities were observed at T2 parallel to the dynamic steady-state balance performance improvement. Previous studies showed that jaw clenching alters balance during upright standing, predictable perturbations when standing on the ground and unpredictable perturbations when standing on an oscillating platform. This study complemented the previous findings by showing positive effects of jaw clenching on dynamic steady-state balance performance.

Los enfrentamientos policiales que involucran el uso de la fuerza o armas de fuego representan situaciones críticas con implicaciones significativas para la seguridad y la vida de las personas. Este artículo se centra en realizar una revisión sistemática, tanto cuantitativa como cualitativa, de estos enfrentamientos, explorando su relación con factores organizacionales y situacionales de relevancia. Entre los resultados, cabe señalar la predominancia de las variables organizacionales en el análisis, en contraposición a las variables situacionales. Las variables situacionales examinadas con mayor frecuencia comprenden la edad, raza, ubicación, tipo de arma, género, resistencia del detenido y experiencia del agente. En contraste, las variables organizacionales que se destacan incluyen el control policial, la estructura organizativa, la gestión interna, y la formación y capacitación de los agentes. Es importante señalar que los estudios revisados presentan ciertas limitaciones, como el tamaño reducido de las muestras y la falta de métodos científicos estandarizados, lo que dificulta la aplicación práctica de los resultados en el ámbito de la capacitación policial. En última instancia, este estudio ofrece recomendaciones para futuras investigaciones, enfocándose en el establecimiento de criterios estandarizados y consensuados que permitan un análisis más unificado de los enfrentamientos policiales. Esta iniciativa contribuiría significativamente a mejorar la comprensión de estos incidentes críticos y, en definitiva, a promover una formación policial más efectiva en su gestión.
Património na estética do seu tempo

Partindo do princípio de que a estética, enquanto perceção que temos do belo na natureza e na arte, molda a nossa visão do mundo, Património na estética do seu tempo explora a relação de interdependência entre o pensamento estético e as posturas para com o património cultural, desde o século XVIII até à atualidade.&lt;br&gt;Entre correntes estéticas e mecanismos próprios da história da arte, parte-se em busca das repercussões de estratégicas esteticamente ponderadas sobre o património cultural. Paralelamente, procuram-se efeitos na perceção estética, resultantes das tendências científicas, filosóficas e ideológicas de diferentes períodos históricos, capazes de se repercutir também sobre os expedientes patrimoniais. Através da apreciação construída em cada época sobre a beleza dos seus monumentos, ruínas e objetos arqueológicos, obras de arte e manifestações culturais, questiona-se até que ponto terá o património sido, afinal, condicionado pela estética do seu tempo.
A ideia de justiça baseada na mitologia
Authors: Schmidt Rodrigues Massaro Rubens Luiz
Published: February 2024

No curso da evolução da humanidade, o mito serviu como um elemento de integração social, contando com os aspectos cultural, religioso e moral. Ele serve para explicar fenômenos que não podem ser comprovados ou validados por meios científicos. Em outras palavras, há uma aceitação da veracidade do mito, ainda que careçam de comprovações científicas. A Grécia Antiga foi palco de ampla utilização dos mitos para explicarem o mundo, seus fenômenos e relações sociais. Ali, o mito serviu para estabelecer valores que fazem parte da ideia de justiça. A celeuma sobre a contribuição dos mitos para desenvolvimento da ideia de justiça parte do pressuposto de que o ser humano precisa, de alguma forma, conseguir compreender fatos e circunstâncias que permeiam a ideia de justiça. Por mais que a civilização humana já tenha evoluído a ponto de refutar a explicação de boa parte dos mitos, sua herança na afirmação de valores existe até os dias de hoje, sendo inclusive objeto de debate entre os operadores do direito. O mito ajudou a moldar uma ideia de justiça que se difundiu social e culturalmente

Este artigo trata da educação de migrantes venezuelanos no Brasil. Tem por objetivo geral analisar quais as demandas educacionais especializadas das crianças e dos adolescentes migrantes venezuelanos, no processo de inclusão no sistema educacional brasileiro. Quanto aos objetivos específicos, são estes: contextualizar a migração venezuelana para o Brasil; apresentar a inclusão escolar de crianças e adolescentes migrantes venezuelanos, no Brasil; e analisar as demandas educacionais especializadas de crianças e adolescentes migrantes venezuelanos, no sistema educacional brasileiro. O problema de pesquisa formulado foi o seguinte: considerando o fluxo venezuelano para o Brasil, bem como a garantia do direito universal à educação, quais as demandas educacionais especializadas de crianças e adolescentes migrantes venezuelanos, no processo de inclusão no sistema educacional brasileiro? Partiu-se da hipótese de que as peculiaridades da conformação do fluxo migratório venezuelano – o qual contempla povos originários de variadas etnias, como Warao, Pemon, Eñepá, Kariña e Wayuú – demandam ações escolares especializadas, mediante práticas pedagógicas diferenciadas, as quais respeitem suas culturas e modos de vida, e promovam uma educação intercultural. Foram utilizados o método de abordagem dedutivo, o método de procedimento monográfico e as técnicas de pesquisa bibliográfica e documental. Os resultados revelaram que a educação, no Brasil, tem desconsiderado as necessidades educacionais especializadas das crianças e dos adolescentes migrantes venezuelanos, pertencentes às comunidades indígenas.
Study on properties of CaF2–CaO–Al2O3–MgO–B2O3 electroslag remelting slag for rack plate steel

Published: February 2024

The loss of boron (B) in the rack plate steel during the electroslag remelting process has a significant impact on its mechanical properties. Therefore, it is necessary to design appropriate slags to suppress the loss of B. CaF2–CaO–Al2O3 phase diagram was calculated to determine the basic slag. The influence of MgO and B2O3 on the performance of the basic slag was studied to determine the optimal amount of MgO addition. The equilibrium reactions between rack plate steel and the 50.48 mass% CaF2–24.81 mass% CaO–24.71 mass% Al2O3–2 mass% MgO-y mass% B2O3 (y was 1–10) slag were studied to examine the variation in B content in the steel. Results indicate the presence of a temperature-qualified eutectic point in the CaF2–CaO–Al2O3 phase diagram. With an increase in MgO content in the slag, the melting temperature of the basic slag initially decreases and then increases, while the electrical conductivity decreases. On the other hand, B2O3 reduces the melting point of the slag and increases the equilibrium B content in the steel. The 50.48 mass% CaF2–24.81 mass% CaO–24.71 mass% Al2O3–2 mass% MgO-y mass% B2O3 (y was 5–7) slag can achieve the target range of B content in the steel, and its viscosity meets the requirements of electric slag remelting.
Regression(s) discontinuity: Using bootstrap aggregation to yield estimates of RD treatment effects
Authors: Long Mark C. , Rooklyn Jordan
Published: February 2024

Following Efron (2014), we propose an algorithm for estimating treatment effects for use by researchers employing a regression-discontinuity (RD) design. This algorithm generates a set of estimates of the treatment effect from bootstrapped samples, wherein the polynomial-selection algorithm developed by Pei, Lee, Card, and Weber (2021) is applied to each sample, the average of these RD treatment effect (RDTE) estimates is computed and serves as the overall estimate of the RDTE. Effectively, this procedure estimates a set of plausible RD estimates and weights the estimates by their likelihood of being the best estimate to form a weighted-average estimate. We discuss why this procedure may lower the estimate’s root mean squared error (RMSE). In simulation results, we show that this better performance is achieved, yielding up to a 5% reduction in RMSE relative to PLCW’s method and a 16% reduction in RMSE relative to Calonico, Cattaneo, and Titiunik’s (2014) method for bandwidth selection (with default settings).
Dirac exciton–polariton condensates in photonic crystal gratings
Authors: Sigurðsson Helgi , Nguyen Hai Chau , Nguyen Hai Son
Published: February 2024

Bound states in the continuum have recently been utilized in photonic crystal gratings to achieve strong coupling and ultralow threshold condensation of exciton–polariton quasiparticles with atypical Dirac-like features in their dispersion relation. Here, we develop the single- and many-body theory of these new effective relativistic polaritonic modes and describe their mean-field condensation dynamics facilitated by the interplay between protection from the radiative continuum and negative-mass optical trapping. Our theory accounts for tunable grating parameters giving full control over the diffractive coupling properties between guided polaritons and the radiative continuum, unexplored for polariton condensates. In particular, we discover stable cyclical condensate solutions mimicking a driven-dissipative analog of the zitterbewegung effect characterized by coherent superposition of ballistic and trapped polariton waves. We clarify important distinctions between the polariton nearfield and farfield explaining recent experiments on the emission characteristics of these long lived nonlinear Dirac polaritons.

Tetrabromobisphenol A (TBBP-A) is an emerging pollutant that enters water resources and affects various marine organisms, such as fish. Consequently, numerous studies globally investigated TBBP-A concentrations in fish fillets of the current study were meta-analyze concentration of TBBP-A in fish fillets and estimate the associated health risks for consumers. The search encompassed international databases, including Science Direct, PubMed, Scopus, Embase, and Web of Science from January 1, 2005, to July 20, 2023. The ranking of countries based on the pooled (Mean) concentration of TBBP-A in fish was as follows: China (1.157 µg/kg-ww) > Czech Republic (1.027 µg/kg-ww) > France (0.500 µg/kg-ww) ∼ Switzerland (0.500 µg/kg-ww) > Netherlands (0.405 µg/kg-ww) > Germany (0.33 µg/kg-ww) > Sweden (0.165 µg/kg-ww)>UK (0.078 µg/kg-ww) > Belgium (0.065 µg/kg-ww) > South Korea (0.013 µg/kg-ww) ∼ Japan (0.013 µg/kg-ww) > Ireland (0.005 µg/kg-ww). The risk assessment showed that the carcinogenic and non-carcinogenic risks of TBBP-A in China and France are higher compared to other countries; however, within all countries, these risks were found to be within acceptable limits.

The fragrant orchid Vanilla chamissonis: an appraisal of the genetic structure of wild populations from Osununú Natural Reserve (Misiones, Argentina)
Authors: Cascales Jimena , Paris Carolina , Gottlieb Alexandra
Published: February 2024

Due to diverse factors the commercial crops of vanilla are highly vulnerable to genetic erosion. The species Vanilla chamissonis Klotzsch has been shown to produce interesting bioeconomic compounds that could diversify the market. In Argentina, the distribution of this fragrant orchid is restricted to specific north-eastern regions, like the Osununú Natural Reserve (at San Ignacio, Misiones), where it grows wildly in sectors (nuclei). This germplasm represents a locally adapted endemism, and thus is a valuable resource worth preserving. Herein, the genetic characterization of unexplored V. chamissonis´ germplasm was accomplished; as well, the specimens´ molecular identification was assessed in a phylogenetic context using nuclear and chloroplastidial markers. The genotyping exposed that, at least, four gene pools contribute to the genetic diversity of these plants, and that ca. 81% of total genetic variation is allocated within populations. Present results suggest a predominance of sexual reproduction, that population N1 emerges as a candidate unit worth conserving, and that a genetic discontinuity was evidenced between northeastern and southwestern nuclei due to their different genetic constitutions. In concurrence, a tenuous isolation by distance was also unveiled. Our phylogenetic results suggest that it is appropriate to consider the vanilla germplasm surveyed as V. chamissonis. The basic knowledge generated in this work will aid in guiding the in-situ conservation and management initiative, ongoing at the Osununú´s reserve.

The long-term success of dental implants depends not only upon implant osseointegration, but also on the surrounding soft tissue health and profile. An ideal emergence profile contributes to the aesthetics of an implant restoration. It maintains long-term implant health by preventing potential food accumulation and forming a barrier against bacterial ingress. This article describes a method for obtaining an impression of implants that will capture the custom guided peri-implant soft tissue contours accurately, thus contributing to a final restoration with favorable aesthetics. We also describe a technique for reducing excess cement in a cement retained implant crown, thereby contributing to the health of the peri-implant tissues.

Published: February 2024

Successfully integrating design for deconstruction (DfD) principles into the construction industry will require articulated design guides and designers’ competencies. This calls for understanding the attributes of designers’ competencies essential for effective DfD implementation. This study explored the attributes of designers’ competencies for DfD implementation in the Ghanaian construction industry. The study adopted an exploratory sequential mixed-design method with an initial qualitative data collection phase followed by a quantitative data collection phase. Responses from the qualitative phase (through interviews) were thematically analysed, while data obtained from the quantitative phase were analysed using mean scores and standard deviations, the normalised value test and the Mann–Whitney U test. The study identified ten attributes of designers’ competencies for DfD implementation. The four key competencies were identified as, in order of importance, proper expertise and motivation, designers’ knowledge of material quality and durability, strong understanding of construction and effective coordination of element and component dimensions. The results of this study shed light on a less explored aspect of competencies for DfD implementation in the construction sector, particularly in the global south. It provides fresh data and new insights into the attributes of designers’ competencies for DfD implementation.
Técnicas de integración: fracciones parciales

Published: February 2024

El cálculo integral es una línea de las matemáticas que requiere la aplicación extensa de preconceptos matemáticos, lo cual constituye un punto de desafío para muchos estudiantes. Además, la integración de funciones se revela como una destreza indispensable para la implementación efectiva de diversos conceptos disciplinares en ingeniería. En consecuencia, resulta imperativo contar con una fundamentación adecuada y pertinente que respalde la aplicación de estos conocimientos en contextos específicos. Las fracciones parciales se presentan como una técnica de integración que abarca diversos conceptos fundamentales de matemáticas, entre ellos la factorización, el despeje de ecuaciones y la división de polinomios. Esta metodología no solo constituye un recurso preciso por sí misma, sino que también sirve como apoyo eficaz para aprovechar las tablas de integración disponibles. De esta manera, los estudiantes no solo desarrollan la competencia necesaria para identificar y aplicar las fracciones parciales, sino que también mejoran su destreza en la utilización de otras estrategias, como la integración por sustitución en su forma más elemental.
Public liability of managers medical entities – selected problems
Authors: Glumińska-Pawlic Jadwiga , Żelasko-Makowska Ewelina
Published: February 2024

Medical entities are, m.in. entrepreneurs within the meaning of the provisions of the Act – Entrepreneurs’ Law, who conduct business activity in all forms provided for its performance. The person authorized to manage such an entity and represent it externally is its manager, who may be a natural person, as well as the management board of a capital company. The entity authorized to manage a medical entity is liable under public law. Liability means an adverse effect for an entity that has violated certain legal norms by its actions, negligence or recklessness. In such a case, it is a question of identifying the guilty person in order to hold him liable, impose sanctions and demand compensation for the damage caused. Liability means an adverse effect for an entity that has violated certain legal norms by its actions, negligence or recklessness. In such a case, it is a question of identifying the guilty person in order to hold him liable, impose sanctions and demand compensation for the damage caused. On the basis of public law, criminal, penal-fiscal liability, tax, financial, official, as well as disciplinary and order liability can be distinguished. However, the most important conclusion for persons managing medical entities is the fact of constantly growing scope of liability and increasing financial sanctions for violation of new public law obligations.
El Río La Plata como sujeto de derechos en Colombia: caracterización del conflicto ambiental que llevó a su reconocimiento
Authors: Vargas-Chaves Iván
Published: February 2024

El presente artículo tiene como objetivo caracterizar un conflicto ambiental en el Río La Plata en Colombia, cuya respuesta, dada por el aparato jurisdiccional ante la instauración de una acción de tutela por la comunidad afectada, permitió declarar a este río como sujeto de derechos a través de la Sentencia 00114 del 19 de marzo de 2019 del Juzgado Único Civil Municipal de La Plata. Método: para cumplir con el objetivo propuesto, se recurrió a una metodología de análisis documental para compilar y estudiar los insumos bibliográficos, documentos relevantes y jurisprudencia en la caracterización de este conflicto. Adicionalmente, se utilizó una matriz de análisis jurisprudencial que permitió estudiar a profundidad la citada sentencia. Resultados: se evidencia cómo la judicialización de conflictos ambientales surge como una respuesta desde el activismo judicial y de la participación ciudadana en materia ambiental, logrando resolver problemáticas a través de figuras novedosas como el reconocimiento de entes de la naturaleza como sujetos de derecho. Conclusión: el aumento significativo de la conflictividad ambiental representa uno de los retos más importantes para el derecho, al concurrir diversos intereses económicos o políticos que ocasionan graves impactos al ambiente y a las comunidades. A lo anterior, se debe sumar una endeble presencia de la institucionalidad del Estado y las autoridades ambientales, evidenciándose una pobre gobernanza ambiental, como fue el caso del conflicto ambiental en el Río La Plata.
hipótese sobre a formação política do Brasil:
Authors: Souza Silva David Junior de
Published: February 2024

O objetivo deste ensaio é contribuir com os estudos sobre a formação política do Brasil. Nesse sentido, olha para o desenvolvimento da história nacional e visa a explicar a esfera política nacional e seu desenvolvimento em conexão com a economia, a cultura e outras esferas da sociedade. Ao falar de política, terá como objeto tanto o processo de conformação da política institucional, como a política e os movimentos e aspirações políticas dos grupos sociais, da assim chamada sociedade civil. A ‘política brasileira’, em sua totalidade, é entendida aqui como essa relação entre ‘política oficial’ e iniciativas e movimentos políticos independentes e autônomos de setores da sociedade civil. Conclui-se que a estrutura política do Estado brasileiro constituiu de forma e com o objetivo de fechar-se em si mesma, impedindo concretamente a entrada dos demais sujeitos sociais na esfera política e a possibilidade de sua influência sobre as decisões políticas, bem como qualquer responsividade do Estado às suas demandas. A repressão violenta das mobilizações sociais populares visando ao silenciamento destas iniciativas políticas foi parte essencial da constituição da política institucional nacional e, por conseguinte, da feição de política brasileira total objetivada pelas elites políticas e econômicas do país. Às iniciativas políticas populares é retirada toda legitimidade por estas mesmas elites, e atribuída violência, disrupção da ordem social e atraso civilizacional. As elites lograram assim e continuam fazendo o trabalho simbólico de deslegitimação das iniciativas políticas populares.
Analiza sytuacyjna w badaniach codzienności miejskiej
Authors: Pawlik Jacek Jan
Published: February 2024

W niniejszym artykule zostanie przedstawione zastosowanie podejścia sytuacyjnego do badań społeczności miejskich. Podejście to jest szczególnie użyteczne w przypadku badań życia codziennego i ściśle łączy się z analizą sieci. Po przedstawieniu założeń teoretycznych tego podejścia, autor analizuje trzy przypadki sytuacji pochodzące z jego badań terenowych prowadzonych w Lomé, stolicy Togo. Okazuje się, że analiza sytuacyjna w połączeniu z analizą strukturalną pozwala na uzyskanie adekwatnego obrazu życia w mieście.
Miasto z ruin: o fotograficznych dokumentacjach wojennej Warszawy
Authors: Ferenc Tomasz
Published: February 2024

Niszczeniu miast w czasach wojennych konfliktów z reguły towarzyszą różne formy rejestracji fotograficznej. Zdjęcia takie powstają z różnych powodów i różne są także ich późniejsze zastosowania. Wiek XX obfituje w historie wielu miast zniszczonych w wyniku zaplanowanych, zmasowanych ataków; wśród nich Warszawa zajmuje pozycję szczególną. W czasie trwania II wojny światowej jej niemal całkowita destrukcja dokonała się w trzech etapach: niemieckiego oblężenia w 1939 r., likwidacji getta w 1943 r. oraz w czasie trwania i pacyfikacji powstania warszawskiego w 1944 r. Każde z tych tragicznych wydarzeń posiada swoją fotograficzną reprezentację. Analiza trzech zbiorów zdjęć ma prowadzić do odpowiedzi na kilka pytań: w jakim celu zostały one wykonane, jak zmieniało się ich znaczenie wraz z upływem czasu, a także jaka jest ich wartość jako „punktów odniesienia” oraz w zaczerpniętym od Johna Tagga ujęciu symbolicznej „waluty”.
Cudze meble w swoim pokoju. Etnograficzny powrót do centrum Tomaszowa Mazowieckiego
Authors: Latocha Sebastian
Published: February 2024

Artykuł realizuje koncepcję antropologicznego, badawczego powrotu do terenu, w którym przed 13 laty zostały przeprowadzone badania etnograficzne, przed rewitalizacją centrum Tomaszowa Mazowieckiego. Autor, inspirując się wierszem Juliana Tuwima, metaforycznie nazywa dynamikę miejskiego krajobrazu „cudzymi meblami w swoim pokoju”. Artykuł stanowi przyczynek do badań nad poetyką etnograficznego powrotu w antropologii społeczno-kulturowej.
Wielokulturowa Łódź jako miejsce pamięci po 1945 roku – zmienność i różnorodność
Authors: Kucner Monika
Published: February 2024

W XIX i XX w. Łódź była miejscem, w którym spotkały się różne kultury, religie, języki i narodowości. Impulsem dla powstania tego wielonarodowego tygla był przemysł tekstylny, który przyciągnął osadników z różnych części Europy. W przeciągu kilku dziesięcioleci z małego miasta Łódź rozwinęła się w wielką metropolię, której wyróżnikiem stała się wielokulturowość, i była miastem wielokulturowym aż do zakończenia II wojny światowej. W wyniku etnicznej segregacji duża część ludności niemieckiej i żydowskiej opuściła miasto. Swoją pamięć o Łodzi pielęgnowała w nowych warunkach społeczno-politycznych, poza Polską, często w rozproszeniu, w niewielkich skupiskach często skoncentrowanych wokół tzw. ziomkostw. Artykuł opisuje, w jaki sposób różne grupy narodowościowe (Polacy, Niemcy, Żydzi) pamiętały o wielokulturowym mieście po 1945 r., opierając się głównie na wspomnieniach i artykułach prasowych. Autorka zwraca również uwagę na fakt, że wszystkie te grupy funkcjonowały w odmiennej rzeczywistości społeczno-politycznej, która determinowała ich pamięć o wielokulturowym mieście.
Pomniki żydowskie w Czechach w oczach władz państwowych i żydowskich w latach 1945–1989
Authors: Soukupová Blanka
Published: February 2024

The study is based on the thesis that monuments are not only highly valuable in terms of art and history, but they also have specific meaning for certain groups of people (nations, minorities). It addresses the problem of what qualities were taken into account by the Czechoslovak state and the Jewish minority in the case of Jewish monuments in the Czech lands after the Second World War. The text concludes that although Czechoslovak elites declared the global artistic and historical significance of Jewish monuments (albeit only in Prague), they failed to provide them with adequate care. Thus, maintenance and repairs (often not entirely successful) were reserved for the Terezín concentration camp and select monuments, mainly in Prague. For the fraction of Jews that survived the Shoah, Jewish monuments became a source of self-esteem and new self-identification with the Czech space. However, not even the small number of Jewish religious communities could prevent the decay of synagogues, cemeteries and other monuments. The situation of poorly secured regional monuments was the most tragic. Jewish communities were often forced to sell them or rent them out. This unfavorable state of affairs worsened after the defeat of the Prague Spring (August 1968), when all hopes for improved monument care associated with the “Golden Sixties” vanished. The period of “normalisation” was then marked by the extensive and rapid demolition of a number of historically valuable buildings, which were forced to “give way to the public interest”.
