La evolución normativa de los delitos contra la Seguridad Social
Authors: Ijalba Pérez Javier
Published: November 2023

El presente trabajo tiene por objetivo el estudio de la evolución normativa de los delitos contra la Seguridad Social (artículos 307, 307 bis, y 307 ter del Código Penal), que han surgido en el actual Estado social y democrático de Derecho como un bien jurídico autónomo y con un carácter propiamente penal. Se comprueba que han sido pocos los autores que se han dedicado al análisis de estos delitos y, menos aún, al estudio de su evolución normativa; cuando, por el contrario, este conocimiento nos puede facilitar una aportación fundamental para responder a las cuestiones que surgen en torno a estas nuevas figuras típicas. La evolución normativa se nos ha revelado dinámica y, además, en constante transformación, sujeta al ritmo de las distintas corrientes doctrinales y jurisprudenciales; en todo caso, conviene acudir al examen de los ensayos recientes para dar respuesta a los cuestionamientos contemporáneos. Este artículo procura ser un análisis exhaustivo, ante un interesante panorama normativo y, a la vez, con el deseo de responder a aquellas cuestiones que determinan y orientan la actual aplicación de los tipos penales.

Published: November 2023

Early gastric cancer is defined as gastric cancer confined to the mucosa or submucosa, irrespective of lymph node metastasis. Endoscopic submucosal dissection is a standard treatment of early gastric cancer. The nonextension sign consists of a protrusion of the surrounding mucosa into the lumen, resembling a trapezoidal shape. This phenomenon occurs when massive submucosal invasion by a cancer increases the thickness and rigidity of the gastric wall and may be useful to differentiate between mucosal or microinvasive submucosal and invasive submucosal cancers. Our case demonstrates the usefulness of the absence of the conventional endoscopic nonextension sign as a marker to decide the adequate approach for mucosal lesions.

Published: November 2023

Black grass jelly sellers at traditional market generally have less attention to hygiene and sanitation. That condition can cause the black grass jelly to be contaminated by bacteria, especially Escherichia coli that can cause diarrhea. The purpose of this study is to analyze higiene sanitation factors that are associated with total plate count and E.coli contamination on black grass jelly. The sample of this study are thirty black grass jelly sellers at 16 traditional market in Semarang that selected by using non-probability sampling with saturation sampling technique. Data analyses include descriptive and analytical by using fisher exact test. Descriptive analysis shows the percentage of total plate count in all black grass jelly are not eligible (100%), all samples are contaminated by E.coli (100%), black grass jelly sanitiation is not eligible (93,3%), seller hygiene is not eligible (93,3%), equipment sanitation is not eligible (93,3%), and enviromental sanitation is not eligible (96,7%). The result of statistical test by using fisher exact shows factor that is correlated with E.coli contamination is black grass jelly sanitation (p =0.002), whereas uncorrelated factors are seller hygiene (p=0.99), equipment sanitation (p=0.99), and environmental sanitation (p=0.99). The advice is that black grass jelly seller should pay more attention to hygiene and sanitation. People should be more careful when they buy black grass jelly. In addition, local health agencies should provide guidance to black grass jelly seller seller about hygiene and sanitation, and do the monitoring more strictly.

Authors: Kaya Nusret
Published: November 2023

2,1,3-Benzothiadiazole (BTD) is a key motif for the chemistry of photoluminescence molecules and its application in lightening technology as well as cell imagining. Evaluating the characteristics and reaction mechanisms of the BTD derivatives in molecular is critical for molecular designing. Research has been turned to BTD-extended derivatives owing to their possible usage in organic photovoltaics, organic light-emitting diodes, liquid crystal devices, dye-sensitized solar cells, and many other applications. Herein, three small molecules with a BTD core, 4,7-di-m-tolylbenzo[c][1,2,5]thiadiazole (NK1), 4,7-bis(3,4,5-trifluorophenyl)benzo[c][1,2,5]thiadiazole (NK2), and 4,7-bis(5-(m-tolyl)thiophen-2-yl)benzo[c][1,2,5]thiadiazole (NK3), were designed and synthesized and their molecular structures were elucidated. Additionally, their photophysical and electrochemical behaviors as well as the aggregation-induced enhanced emission properties were examined to investigate their possible usage in cell imaging and organic electronic applications. The HOMO energy level of molecules has been found as −5.96, −5.58, and −5.60 eV, respectively. In the emission spectra, it was seen that molecules showed green, blue, and red emission, respectively.

Published: November 2023

Accelerated or partially accelerated life tests are particularly significant in life testing experiments since they save time and cost. Partially accelerated life tests are carried out when the data from accelerated life testing cannot be extrapolated to usual conditions. The constant-stress partially accelerated life test is proposed in this study based on a Type-II censoring scheme and supposing that the lifetimes of units at usual conditions follow the inverted Topp–Leone distribution. The Bayes and E-Bayes estimators of the distribution parameter and the acceleration factor are derived. The balanced squared error loss function, which is a symmetric loss function, and the balanced linear exponential loss function, which is an asymmetric loss function, are considered for obtaining the Bayes and E-Bayes estimators. Based on informative gamma priors and uniform hyper-prior distributions, the estimators are obtained. Finally, the performance of the proposed Bayes and E-Bayes estimates is evaluated through a simulation study and an application using real datasets.

The rixosome defined in Schizosaccharomyces pombe and humans performs diverse roles in pre‐ribosomal RNA processing and gene silencing. Here, we isolate and describe the conserved rixosome from Chaetomium thermophilum, which consists of two sub‐modules, the sphere‐like Rix1‐Ipi3‐Ipi1 and the butterfly‐like Las1‐Grc3 complex, connected by a flexible linker. The Rix1 complex of the rixosome utilizes Sda1 as landing platform on nucleoplasmic pre‐60S particles to wedge between the 5S rRNA tip and L1‐stalk, thereby facilitating the 180° rotation of the immature 5S RNP towards its mature conformation. Upon rixosome positioning, the other sub‐module with Las1 endonuclease and Grc3 polynucleotide‐kinase can reach a strategic position at the pre‐60S foot to cleave and 5′ phosphorylate the nearby ITS2 pre‐rRNA. Finally, inward movement of the L1 stalk permits the flexible Nop53 N‐terminus with its AIM motif to become positioned at the base of the L1‐stalk to facilitate Mtr4 helicase‐exosome participation for completing ITS2 removal. Thus, the rixosome structure elucidates the coordination of two central ribosome biogenesis events, but its role in gene silencing may adapt similar strategies.

Published: November 2023

This paper considers the problem of probability distribution construction for a random variable from known numerical characteristics. The problem is of importance in determining the parametric reliability of engineering systems when the numerical characteristics (in particular, the bias and the kurtosis) of an output parameter (state variable) are determined by analytical methods and its distribution must be recovered. This may be done using a four-parameter universal distribution, which allows one to cover certain ranges (preferably, as wide as possible) of the bias and kurtosis coefficients using a single analytical form. The most familiar universal distribution is Gram-Charlier’s, which is a deformation of the normal distribution obtained using a Chebyshev-Hermite orthogonal polynomial expansion. However, in the general case, Gram-Charlier’s distribution function is not a steadily increasing one. For some combinations of the bias and kurtosis coefficients, the density curve may exhibit negative values and multiple modes. Because of this, a search for other universal distributions to cover wider ranges of the bias and kurtosis coefficients is of current importance. The paper analyzes a method of universal probability distribution construction by multiplying the normal density by a perturbing polynomial in the form of a spline (referred to as the spline-perturbed distribution). The idea of a distribution of this type was proposed earlier to account for a nonzero bias coefficient. The spline is constructed based on Hermite’s interpolating polynomials of the third degree with two knots, which have a minimum of parameters and possess a locality property The basic distribution is constructed for a four-knot spline. The paper further develops and generalizes the spline-perturbed distribution to nonzero bias and kurtosis coefficients. Two cases are considered. The first case is a composition of two splines that have four and five knots, respectively. The former and the latter allow one to account for the bias and the kurtosis, respectively. Integral equations are obtained to find the values at the knots of both splines and construct the distribution. The second case is more general and uses one five-knot Hermite spline. The paper shows a way to construct a generalized spline-perturbed distribution without any negative density values or any multiple modes. The knot points are chosen using an enumerative technique. Conditions for the absence of negative density values and multiple nodes are identified.
Regular and compound behavior of a pendulum system in a magnetic field

Published: November 2023

This paper considers the dynamics of an oscillatory dissipative system of two coupled pendulums in a magnetic field. The pendulums are coupled via an elastic element. The inertial components of the pendulums vary over a wide range, and in the analytical study the mass ratio is chosen as a small parameter. The magnetic forces are calculated using the Pade approximation, which best agrees with the experiment. This approximation describes the magnetic excitation to good accuracy. The presence of external inputs in the form of magnetic forces and various types of loads that exist in many engineering systems significantly complicates the mode shape analysis of nonlinear system. Nonlinear normal modes of this system are studied, one mode being coupled and the other being local. The modes are constructed by the multiple-scale method. Both regular and compound behavior is studied as a function of the system parameters: the pendulum mass ratio, the coupling coefficient, the magnetic intensity coefficient, and the distance between the axis of rotation and the center of gravity. The effect of these parameters is studied both at small and at sizeable initial pendulum inclination angles. The analytical solution is compared with the results of a numerical simulation based on the fourth-order Runge?Kutta method where the modes are calculated using the initial values of the variables found in the analytical solution. The numerical simulation, which includes the construction of phase diagrams and trajectories in the configuration space, allows one to assess the dynamics of the system, which may be both regular and compound. The stability of the coupled mode is studied using a numerical-analytical test, which is an implementation of the Lyapunov stability criterion. In doing so, the stability of a mode is determined by assessing the vertical off-trajectory deviation of the mode in the configuration space.

Published: November 2023

Objective: to analyze the emotional response of critically-ill conscious patients during daily hygiene procedures in a Cardiology Intensive Care Unit and to compare it based on the existence of previous experiences or not. Method: a prospective and descriptive study. A 30-item ad hoc survey based on the first-day hygiene procedures was applied to 148 patients. Questions are asked about the feelings during the hygiene procedures and about positive and negative aspects of the experience. The patients are compared based on whether they had been already subjected to hygiene procedures or not. Results: 67.6% were men and their mean age was 67±15 years old; 45.9% proved to be satisfied, 27% felt embarrassment and 86.3% were grateful to the professionals for talking to them during the hygiene procedures. 33.1% of the patients had never been subjected to hygiene procedures in bed, were significantly younger and single, and presented a lower cleanliness sensation. 32% stated that they would like for a family member to collaborate in the hygiene procedures. Conclusion: the patients do not feel that their intimacy is invaded when they are subjected to hygiene procedures and appreciate communication with the health personnel while this care is provided. Those who had never been subjected to hygiene procedures in bed are younger, feel more embarrassed and are more disturbed by interruptions, in addition to being more aware of them.

Objective: this study evaluated burnout symptoms among physicians and nurses before, during and after COVID-19 care. Method: a cross-sectional comparative study in the Pulmonary Care unit of a tertiary-level public hospital. The Maslach Burnout Inventory was used. Results: 280 surveys were distributed across three periods: before (n=80), during (n=105) and after (n=95) COVID-19 care; 172 surveys were returned. The response rates were 57.5%, 64.8% and 61.1%, respectively. The prevalence of severe burnout was 30.4%, 63.2% and 34.5% before, during and after COVID-19 care (p<0.001). Emotional exhaustion (p<0.001) and depersonalization (p=0.002) symptoms were more prevalent among nurses than among physicians. Severe burnout was more prevalent in women, nurses and night shift staff. Conclusion: the high prevalence of burnout doubled in the first peak of hospital admissions and returned to pre-pandemic levels one month after COVID-19 care ended. Burnout varied by gender, shift and occupation, with nurses among the most vulnerable groups. Focus on early assessment and mitigation strategies are required to support nurses not only during crisis but permanently.

O foco na avaliação precoce e nas estratégias de mitigação é necessário para apoiar os enfermeiros não apenas durante a crise, mas de forma permanente.
“We are human beings, we also get sick”: presenteeism in nursing workers in a pandemic context
Authors: Galon Tanyse , Navarro Vera Lucia
Published: November 2023

Objective: to understand the experiences of presenteeism in nursing professionals from hospital services during the COVID-19 pandemic. Method: qualitative study, anchored in historicaldialectical materialism. Thirty nursing workers participated in the research, divided into six online focus groups, analyzed based on Hermeneutics-Dialectics. Results: three categories of analysis emerged: “Worsening presenteeism in the pandemic context”; “Why did I go to work sick: the worker’s decision or precarious work?”; “Old problems, permanent struggle”. Despite the illness of professionals by COVID-19, presenteeism in the pandemic was marked by institutional pressure to return to work, mental suffering and lack of recognition and humanization. Among the factors that led to presenteeism, the lack of testing for COVID-19, concern for patients, co-workers and managers, as well as fear of losing their job and/or financial benefits, stood out. Faced with this scenario, workers called for a new reality in which rights such as decent wages and safe working conditions are guaranteed. Conclusion: the pandemic context revealed a worsening of presenteeism among nursing professionals. The results pointed to the importance of concretely valuing nursing in legal terms and beyond honors.

Abstract Beaucarnea inermis is an endemic species from Northeast Mexico, in the states of San Luis Potosí and Tamaulipas. It is appreciated as an ornamental plant, so its populations are subject to the poaching of individuals for illegal trade. Previous studies determined that their populations have been affected due to the disturbance since the incidence of anthropogenic activities affects the viability of the species. Here we determine the current conservation status of B. inermis and identify their main risk factor by performing an extinction risk assessment based on the Annex II “Method for Evaluation of Risk of Extinction of Plants in Mexico”. We studied 10 populations of B. inermis from protected and non-protected areas in San Luis Potosí and Tamaulipas. We considered the MER criteria: A) geographical distribution characteristics, B) habitat characteristics, C) intrinsic biological vulnerability, and D) impact of human activity. Using field and analyzed data, the MER assessment gives 1.91 points that confirm B. inermis is correctly classified as an Endangered species. The natural protected areas where the species occurs represent cores for its protection; however, the surface of these areas may not be sufficient without biological corridors that connect them.

Resumo Objetivo: A pesquisa analisou a percepção dos empreendedores das cidades de São Paulo e São Luís em relação às políticas públicas implementadas durante a pandemia para o enfrentamento da crise da Covid-19 e como elas contribuíram para a sobrevivência das micro, pequenas e médias empresas (MPME) em situações adversas. Originalidade/valor: Ante o avanço da curva de contágio da Covid-19, os governos de todo o mundo adotaram medidas de contenção da doença. Tais medidas trouxeram impactos negativos para as organizações, em especial para as MPME, que são mais suscetíveis aos efeitos da crise. Nessas situações, o papel do Estado na promoção de políticas públicas de enfrentamento da crise é fundamental e pode representar a diferença entre a sobrevivência e recuperação e o encerramento das atividades do negócio. Design/metodologia/abordagem: Uma pesquisa qualitativa com abordagem exploratória de caráter descritivo foi desenvolvida por meio de um estudo empírico realizado em duas etapas, combinando as respostas de um questionário no Google Forms e entrevistas com 48 empreendedores de MPME nas cidades de São Paulo e São Luís. A análise de conteúdo foi apoiada pelo software Atlas.ti. Resultados: Cinco categorias de políticas públicas foram criadas: 1. financeiras, 2. tributárias, 3. operacionais, 4. políticas e 5. de saúde. Em situações adversas, o apoio governamental é fundamental para a sobrevivência e recuperação das MPME. Concluiu-se que, embora as políticas de apoio tenham sido consideradas insuficientes pelos empreendedores pesquisados, aqueles que conseguiram ter acesso relataram que elas foram fundamentais para a manutenção do negócio.

Resumo Objetivos: avaliar os fatores associados à disfunção sexual entre as mulheres de meia-idade. Métodos: estudo de corte transversal e analítico realizado com mulheres climatéricas atendidas em uma Unidade de Estratégia de Saúde da Família no município de Montes Claros-MG, Brasil. As mulheres elegíveis responderam a um formulário contendo questões sociodemográficas, comportamentais, antropométricas, fatores ginecológicos e sexualidade. Utilizou-se o Índice e Massa Corporal e a circunferência da cintura para avaliar o estado nutricional e risco metabólico. Para avaliar a qualidade de vida e o desempenho sexual foram utilizados a Menopause Rating Scale e o Quociente Sexual -Versão Feminina, respectivamente. Empregou-se análise bivariada e regressão múltipla hierarquizada para identificar fatores associados à disfunção sexual no climatério. Resultados: dentre 195 mulheres, 29,6% apresentaram disfunção sexual. A prevalência de desempenho sexual insatisfatório foi maior entre as mulheres que declararam sintomas climatéricos moderados a graves (OR = 2,47) e o menor grau de escolaridade (OR = 1,95). No entanto, a idade da menarca abaixo de 12 anos (OR = 0,43) e a cor de pele não branca (OR = 0,36) parecem ter efeito protetor para o bom desempenho sexual. Conclusão: a prevalência de disfunção sexual foi elevada e o nível de escolaridade e a sintomatologia climatérica foram fatores associados a esse resultado.

ABSTRACT Objective: The benefit of atropine in pediatric tracheal intubation is not well established. The objective of this study was to evaluate the effect of atropine on the incidence of hypoxemia and bradycardia during tracheal intubations in the pediatric emergency department. Methods: This is a single-center observational study in a tertiary pediatric emergency department. Data were collected on all tracheal intubations in patients from 31 days to incomplete 20 years old, performed between January 2016 and September 2020. Procedures were divided into two groups according to the use or not of atropine as a premedication during intubation. Records with missing data, patients with cardiorespiratory arrest, cyanotic congenital heart diseases, and those with chronic lung diseases with baseline hypoxemia were excluded. The primary outcome was hypoxemia (peripheral oxygen saturation ≤88%), while the secondary outcomes were bradycardia (decrease in heart rate >20% between the maximum and minimum values) and critical bradycardia (heart rate <60 bpm) during intubation procedure. Results: A total of 151 tracheal intubations were identified during the study period, of which 126 were eligible. Of those, 77% had complex, chronic underlying diseases. Atropine was administered to 43 (34.1%) patients and was associated with greater odds of hypoxemia in univariable analysis (OR: 2.62; 95%CI 1.15–6.16; p=0.027) but not in multivariable analysis (OR: 2.07; 95%CI 0.42–10.32; p=0.37). Critical bradycardia occurred in only three patients, being two in the atropine group (p=0.26). Bradycardia was analyzed in only 42 procedures. Atropine use was associated with higher odds of bradycardia in multivariable analysis (OR: 11.00; 95%CI 1.3–92.8; p=0.028). Conclusions: Atropine as a premedication in tracheal intubation did not prevent the occurrence of hypoxemia or bradycardia during intubation procedures in pediatric emergency.

Published: November 2023

ABSTRACT Introduction: With the abundant use of the internet, patients undergoing or interested in orthodontic treatment try to use it to obtain information on pain during treatment. However, YouTube™ is unregulated and may potentially contain inaccurate information. Objectives: Thus, this study aimed to evaluate the scientific quality of the videos on YouTube™ related to orthodontic pain management. Methods: A total of 62 videos related to orthodontic pain management were included in the study. All videos were evaluated by two experienced orthodontists. The video uploader, content, length, upload date, time since upload, number of views, comments, likes, dislikes, Interaction index, and Viewing rate of the videos were recorded and evaluated. The videos were scored using the Quality Criteria for Consumer Health Information (DISCERN), Global Quality Scale (GQS), and Audio-Visual Quality (AVQ), and divided into two groups: Doctors and Non-doctors. Results: The mean DISCERN score was 2.56 ± 0.91, the GQS score was 2.56 ± 1.06, and AVQ was 2.48 ± 0.68. A statistically significant difference was found in DISCERN score of videos uploaded by Doctors compared to Non-doctors, but no statistically significant difference was found in GQS and AVQ scores between both groups (p> 0.05). Conclusions: The videos uploaded by Doctors were better in terms of quality and reliability, as compared to Non-doctors; and the AVQ of the videos uploaded by both groups was adequate. Despite that, both groups did not serve as a good source of information. YouTube™ cannot be considered a reliable source of information in terms of quality and reliability on videos related to orthodontic pain management.
Silver nanoparticles eliminate hyperhydricity in micropropagated Lavender

Published: November 2023

Abstract It is challenging to plant lavender outside of suitable conditions. This economically important plant requires optimal conditions to germinate and produce a high yield. To increase the quality of this plant, tissue culture is utilized. The most problematic aspect of lavender micropropagation is that cytokinin (CK) causes hyperhydricity (HH) during the shooting process. Consequently, this study was conducted to resolve HH in micropropagated lavender plantlets. Different concentrations of silver nanoparticles (AgNPs) were applied in conjunction with 1.0 mg L-1 6-benzylaminopurine (BA). Then, the performance of HH, growth and development, as well as total phenolic (TPC) and total flavonoid (TFC) content, were evaluated. The application of 20 mg L-1 of AgNPs was found to be the optimal method for halting HH. Although shoot proliferation was lower than in BA-supplemented media-grown plants, adding this concentration of AgNPs improved shoot and root quality. An increase in secondary metabolites and antioxidant activity may have caused the remedy of HH.

This experiment was conducted in a factorial trial with two factors, including SNP at four levels of 0, 50, 100 and 200 μM and putrescine at four concentrations of 0, 1, 2, and 4 mM with three replications in hydroponic conditions in the greenhouse. Some of the recorded traits included the number of leaves plant-1, leaf area, fresh and dry leaf weight, as well as determination of soluble sugars, and total protein. Also, in the post-harvest stage, the recoded traits included malondialdehyde (MDA) content, relative fresh weight, and vase life. SNP at a concentration of 100 μM was found to improve morphological traits including fresh and dry weight of leaf (4.3 and 1.4 g, respectively) compared to the control. It also increased total protein (0.85 mg g-1 FW), decreased postharvest MDA content (0.32 µM g-1 FW), and increased vase life (23.66 days) at 100 μM level, and increased leaf area (7671 mm2) and flower relative fresh weight (27.65%) at 200 μM level. Among different rates of putrescine, 4 mM putrescine was associated with higher leaf area (8056.7 mm2), fresh and dry leaf weight (4.3 and 1.3 g, respectively), soluble sugars (4.63 mg g-1 FW), lower post-harvest MDA content (0.32 µM g-1 FW), and increased duration of vase life (26 days). In general, SNP and putrescine improved rose growth parameters and post-harvest traits.

Abstract The characterization of flowering phenophases and morphoagronomic knowledge is important for crop management and harvest programming. This study aimed to evaluate the duration of reproductive phenophases and conduct morpho-agronomic characterization of gladiolus cultivars. Two experiments were conducted, one in a shaded environment and the other in a full sun environment. A split-plot design in randomized blocks was used, which consisted of the planting system with single rows and twin rows in the plots and the cultivars (White Goddess, Traderhorn, Peter Pears, and Gold Field) in the subplots. The reproductive phenophases, plant development and productivity of each cultivar were evaluated. The flowering cycle lasted from 58 to 65 days when the cultivars were grown in the shaded environment, while the duration of this cycle ranged from 78 to 87 days in the full sun environment. The yield of the Gold Field cultivar was significantly higher when grown in twin rows compared to single-row planting. A shaded environment and twin-row planting are the recommended conditions for the cultivation of gladiolus in the state of Mato Grosso since they promote better stem development and early flowering of the cultivars. The Peter Pears and Gold Field cultivars are recommended for cultivation in the region due to their greater production of marketable stems.

Published: November 2023

In this study, the response surface approach was employed to predict and optimize the biodiesel yield. Blend of Karanja and Chlorella vulgaris oil was used in a volumetric ratio of 75:25 to lower the free fatty acid content. The biodiesel production process parameters from this hybrid oil were optimized through a single-step transesterification process. The optimized conditions resulted in a maximum biodiesel yield of 97.55% . These conditions included a catalyst amount of 1.09% (w/w), a reaction time of 91.47 minutes, a reaction temperature of 56.86°C, and a methanol-to-oil molar ratio of 8.46:1. The experimental biodiesel yield was compared with the predicted response obtained from the response surface methodology (RSM). The comparison demonstrated good agreement between the experimental and predicted values.
VALIDATING PRACTICES AND MESSAGES THAT PROMOTE MINORITIZED WOMENâS ENGINEERING CLASSROOM BELONGINGNESS: AN INTERSECTIONAL APPROACH
Authors: Verdin Dina , Castillo A. Lili
Published: November 2023

Establishing and sustaining a sense of belonging is a necessary motivation with particular implications
for student learning, including in engineering. Validation is a crucial component of the learning
process, as it helps individuals feel a sense of belonging and purpose within their educational environment.
Yet, there is a dearth of literature that speaks to practical classroom practices that validate
women's sense of belonging without putting the onus directly on them. Therefore, the aim of this study
was to examine validating practices and messages that contributed to women's engineering classroom
belongingness. This study used survey data of engineering students collected from nine 4-year institutions.
Multiple regression analysis with interaction effects was used to understand how practices and
messages differentially validated classroom belongingness when considering an intersectional lens.
Our findings identified strategies that could help remedy classroom belongingness for women based on
racial/ethnic representation in engineering, parents' level of education, transfer status, and institution
type. Instructors have a crucial role to play in fostering student belongingness, but it must be done
with attention to the different practices and messages that speak to students about their fit in engineering.
Identifying specific validating mechanisms practiced by both instructors and peers can provide
engineering educators with concrete strategies to continue supporting women's sense of belonging in
the engineering culture. We conclude with recommendations of how to enact validating messages and
teaching practices to promote classroom belongingness.
Caught Between Manga and the Graphic Novel: Two Cartoonists' Trajectories in Contemporary Argentinian “National Comics”
Authors: Labra Diego
Published: November 2023

What do Ignacio Minaverry and Ciro Berliac’s trajectories say about comics in contemporary Argentina? By crossreferencing their body of work with the discourses surrounding them, this article explores both as a blueprint for two different positioning strategies within the comics field. Growing up in thee arly 1990s, they were both brought up in a time of daunting change, as the remains of a once-mighty national comic industry finally disappeared and a nascent (imported) comic book shop circuit exposed them to new graphic narratives, such as manga. After publishing what was labeled as the “first Argentinian manga”, Minaverry “edited” his own biography/bibliography and phased out any overt “mangaesque” traits in his cartooning in order to fit into a field increasingly geared towards the graphic novel, and was rewarded for it. In contrast, Berliac publicly “transitioned” from cartoonist to “mangaka” in defiance of what he understood was the chauvinist establishment of Argentinean “national comics” in a (successful) bid to gain notoriety. As conclusion, contrasting both trajectories reveals the importance of the discursive and material tensions between "national" and foreign in a peripheral comics field, playing a hefty role in its mechanics of gatekeeping and the distribution of symbolic capital.
Probióticos en cerdos: resultados contradictorios

Published: November 2023

El uso de antibióticos a niveles subterapéuticos como promotores de crecimiento, generan preocupación a nivel mundial por la posible resistencia de algunos microorganismos a ciertos antibióticos, que podrían de manera potencial transferir genes resistentes desde los animales hacia la microbiota humana; existen alternativas como los probióticos y prebióticos, que estimulan la inmunidad del huésped y no tienen residuos en los productos de origen animal, por lo cual se pretende en esta investigación estudiar sus efectos en la nutrición porcina e identificar las principales falencias que se presentan en la experimentación que se realiza con estos. Los probióticos son microorganismos vivos que cuando se administran en la cantidad adecuada, le generan un efecto benéfico al huésped, disminuyen los problemas de salud y pueden aumentar la productividad, gracias a que con ellos se pueden afectar las proporciones de las diferentes especies de bacterias en la microbiota del tracto gastrointestinal. No obstante, en cuanto a su efecto como promotores de crecimiento los resultados son contradictorios, en gran medida por la diversidad de cepas, especies de microorganismos, dosis, la forma de administración; así como también la diferente composición de las dietas utilizadas en los bioensayos.

Yajé, chamanismo Kamëntsá y nuevos chamanismos urbanos: mitopoiesis y decolonización
Authors: Marín Valencia Alejandro
Published: November 2023

Objetivo. Este artículo pretende reflexionar sobre la psicofarmacología del yajé, el sistema chamánico Kamëntsá y los neochamanismos urbanos, analizando los estados modificados de conciencia y su relación con procesos de producción simbólica. Metodología. Se realizó una extensa revisión bibliográfica, etnográfica y teórica, apoyada en datos etnográficos recogidos en estadías de campo entre los indígenas Kamëntsá del departamento del Putumayo (Colombia) y en los diferentes escenarios neochamánicos de la ciudad de Medellín. Resultados y conclusiones. El yajé es un brebaje enteogénico que al ser consumido induce profundos cambios en la conciencia, permitiendo la obtención de experiencias holotrópico/dialógicas que activan procesos dinámicos de producción de significado o mitopoiesis, que han derivado a su vez en diversas formas de decolonización del pensamiento manifiestas tanto dentro del marco simbólico del chamanismo tradicional Kamëntsá como en los procesos de resignificación de conocimientos y tradiciones indígenas dentro de los nuevos chamanismos urbanos.
