Published: January 2023

Abstract.

Ordinal logistic regression is a statistical method for analyzing response variables that have ordinal data scales and consist of three or more categories, while the predictor variables used can be categorical or quantitative data. The model commonly used in ordinal logistic regression is the Proportional Odds Model (POM). POM has strong assumptions that can lead to misinterpretation if the assumptions are violated, the general assumption of the model is known as the proportional odds assumption. So that an alternative model that needs to be considered when the assumptions are not met is the Partial Proportional Odds Model (PPOM), which is a model that weakens the proportionality assumption only for some predictor variables in the model. The purpose of this study is to apply PPOM in cases of women's first marriage age and what factors affect the age at first marriage based on the PPOM model. PPOM parameter estimation using Maximum Likelihood Estimation (MLE) method obtained results that are not close-form so that Newton-Raphson iteration is needed. Based on the test results, it is found that the predictor variables that affect the age at first marriage of women are education, place of residence and economy.

Regresi logistik ordinal merupakan salah satu metode statistika untuk menganalisis variabel respon yang mempunyai skala data ordinal dan terdiri dari tiga kategori atau lebih, sedangkan variabel prediktor yang digunakan dapat berupa data kategori atau kuantitatif. Model yang umum digunakan dalam regresi logistik ordinal adalah Proportional Odds Model (POM). POM mempunyai asumsi kuat yang dapat menyebabkan kesalahan interpretasi jika asumsi dilanggar, asumsi umum dari model dikenal dengan asumsi proportional odds. Sehingga model alternatif yang perlu dipertimbangkan ketika asumsi tidak terpenuhi adalah Partial Proportional Odds Model (PPOM), yakni model yang melemahkan asumsi proporsionalitas hanya untuk beberapa variabel prediktor dalam model. Tujuan penelitian ini adalah mengaplikasikan PPOM pada kasus usia kawin pertama wanita dan faktor apa saja yang mempengaruhi usia kawin pertama berdasarkan model PPOM. Estimasi parameter PPOM menggunakan metode Maximum Likelihood Estimation (MLE) diperoleh hasil yang not close-form sehingga diperlukan iterasi Newton-Raphson. Berdasarkan hasil pengujian diperoleh bahwa variabel prediktor berpengaruh terhadap usia kawin pertama wanita adalah pendidikan, tempat tinggal dan ekonomi.

“O conceito e a lei dos direitos humanos declaram que todo indivíduo pode fazer reivindicações legítimas de determinadas liberdades e benefícios. Os direitos humanos são uma ideia política com base moral e estão intimamente relacionados com os conceitos de justiça, igualdade e democracia. Eles são uma expressão do relacionamento que deveria prevalecer entre os membros de uma sociedade e entre indivíduos e Estados. Os direitos humanos devem ser reconhecidos em qualquer Estado, grande ou pequeno, pobre ou rico, independentemente do sistema social e econômico que essa nação adota. Nenhuma ideologia política que não incorpore o conceito e a prática dos direitos humanos pode fazer reivindicações de legitimidade. Apesar dos vários tratados e declarações adotados com a consciência e o consenso da comunidade internacional a triste realidade é que nenhum dos direitos declarados é respeitado uniformemente no mundo inteiro. A maciça violação dos direitos e liberdades básicos faz
com que o ideal de uma vida digna e decente para todos os cidadãos do mundo torne-se algo muito distante. Ao mesmo tempo, vivemos em uma era que apresenta oportunidades, únicas para levar adiante a causa dos direitos humanos. A competição lógica da Guerra Fria, em cujo nome cometeu-se e justificou-se tantos abusos, acabou. Os movimentos para a democracia, guiados por um compromisso de promover os direitos humanos, continuam obtendo bons resultados em todo o mundo. E, finalmente, há o reconhecimento crescente de que o respeito aos direitos humanos é imperativo para a sobrevivência da humanidade." Direitos Humanos - impulsionar ou recuar na luta pela suprema dignidade da vida, pelos direitos e pela felicidade das pessoas? E que ações concretas estamos realizando por esses direitos? Esta é a regra básica tanto do indivíduo como do Estado” (IKEDA apud CUNHA, 1998).

Fácil concluir que pelo devido processo legal constitucional a equidade, que se identifica com a razoabilidade, com a proporcionalidade e com a vedação do excesso, pode e deve estar presente em toda decisão judicial, independentemente das equivocadas limitações contidas no parágrafo único do art. 140 do Código de Processo Civil de 2015, pois essas limitações não se harmonizam com o Estado constitucional de Direito e decorrer de uma premissa errônea, ou seja, de considerar a equidade um instituto diverso do da razoabilidade.

Origen y ocaso de la Preparatoria Popular Lenin, Morelia (1977-1979)
Authors: Armas Madrigal Erika
Published: January 2023

En la década de 1970 en Morelia se dio la fundación de escuelas populares, con las que se buscó dar cabida a los estudiantes que no podían estudiar, ya fuera porque no había lugar en las escuelas o porque no tenían los recursos para entrar aunque hubiese lugares, el acontecimiento se repitió al inicio de cada ciclo escolar. En ese contexto fue que se fundó en septiembre de 1977, a manos de los estudiantes nicolaitas radicalizados, la Preparatoria Popular Lenin, que ofreció estudios a quienes el sistema capitalista dejó fuera de los servicios educativos, además, la prepa tuvo la misión de formar cuadros políticos para llevar a la sociedad al socialismo. La preparatoria, que desde su fundación tuvo oposición por parte de algunos sectores universitarios, estuvo laborando por un periodo aproximado de dos años, ya que no lograron el reconocimiento de sus estudios por parte de la Universidad Michoacana, pues se abrieron más preparatorias de la Universidad que absorbieron a los estudiantes y algunos profesores de la Preparatoria Lenin, por lo que finalmente se extinguió en 1979.

Individuals spend 90% of their time indoors, primarily at home or at work. Indoor environmental factors have a signifcant impact on human well-being. It was a longitudinal study that assessed the major factors that reduce indoor air quality, namely particulate matter, and bio-aerosols, using low-cost sensors and the settle plate method, respectively also to determine the effect of atmospheric parameters and land use patterns in households of commercial, industrial, residential, slum, and rural areas of the city. PM2.5 concentration levels were similar in most parts of the day across all sites. PM10.0 concentration levels increased indoors in a commercial area. PM2.5 concentration showed a negative correlation with temperature and a positive correlation with relative humidity in some areas. Very high values of PM2.5 concentration and PM10.0 concentration have been observed in this study, inside households of selected rural and urban areas. Pathogenic gram-positive cocci, gram-positive rods, Aspergillus, and Mucor species were the most common bacterial and fungal species respectively found inside households. This study examined particulate matter concentration along with bio-aerosols, as very less studies have been conducted in Jaipur the capital of Rajasthan, a state in the western part of India which assessed both of these factors together to determine the indoor air quality. Rural households surrounding the periphery of the city were found to have similar pollution levels as urban households. So, this study may form the basis for reducing pollution inside households and also for taking suitable measures for the reduction of pollution in the indoor environment.

Wood-apple is a rare plant that is almost extinct, so efforts are needed to increase the population. Wood-apple is generally propagated generatively. Wood-apple seeds need 2-3 weeks to germinate, so when germinated many seeds are rotten before germination. Soaking in gibberellins is one way that can be done to shorten germination. The study aimed to determine the effect of concentration and duration of soaking in gibberellins on germination and growth of wood-apple seedlings. The study consisted of two factors which were designed in a completely randomized design. The first factor was the concentration of gibberellins, consisting of three levels, namely 25 ppm (k1), 50 ppm (k2), and 75 ppm (k3). The second factor was soaking time, consisting of three levels, namely 6 hours (l1), 9 hours (12), and 12 hours (13), so there were 9 treatment combinations and one treatment without gibberellins (control), each treatment was repeated three times. The results showed that the gibberellin treatment increased the height of the seedlings compared to the control. The concentration of gibberellins affects the length and diameter of the hypocotyl and the length of the radicle. Concentrations of 50 and 75 ppm resulted in higher hypocotyl diameter and radicle length than 25 ppm. The concentration of 75 ppm gave the highest hypocotyl length. Soaking time affects the percentage of germination, germination rate, and growth rate of wood-apple seedings. Soaking in gibberellins for 12 hours gave a faster growth rate of seedlings than 6 and 9 hours.

A technology fo the formation of porous tubular polymer scaffolds (PTPS) made of polycaprolactone (PCL) with the necessary physical and mechanical characteristics (Young’s modulus 5.5 ± 1.1 MPa, breaking force 10.9 ± 1.6 N and maximum elongation 477 ± 38 %) has been developed. Samples obtained by electrospinning from 2 ml of a 10 % PCL solution in dichloromethane (voltage between electrodes 25 kV, solution delivery rate 4 ml/h, distance to the collector 100 mm, rotation speed of the substrate rod 1000 rpm) showed a minimum surgical permeability of 30.4 ± 1.5 ml/(cm2·min). It is proved that the proposed bioactive coating based on heparin and platelet lysate does not affect the surface structure and physical and mechanical characteristics of the scaffold. It has been shown in vitro that samples of modified PTPS do not exhibit cytotoxicity and hemolytic activity, and improvement of hemocompatible properties occurs due to a decrease in the number and degree of activation of adhered platelets.

TiNi shape memory alloys exhibiting martensitic transformations are attractive materials in the industry of micromechanical systems. The key issue responsible for degradation of functional properties of TiNi during operation is residual stresses arising from the sample processing and surface treatments. In this work, we investigated TiNi substrates modified after synthesis of Ti – Ni – Ta – Si surface alloys (SA) by additive thin film electron-beam (ATF-EB) method. The effect of electron-beam treatments of the system “[Ti – Ni – Ta – Si]SA/TiNi substrate” at the energy density (ES = 1.7 J/cm2) and pulse number n = 10 on the elastic-stress state of the B2 phase in TiNi substrate has been studied. Detailed analysis by X-ray diffraction (XRD) and transmission electron microscopy (TEM) has shown the formation of two isostructured B2 phases with different lattice parameters, chemical composition, and microstructure. It has been found that changes in the B2 lattice parameters are closely related to the variation of the chemical composition and residual elastic stresses of the first kind. The study of residual stresses in the samples reveals that compression stresses in the direction perpendicular to the irradiated surface reach a value of –350 MPa. After additional electron-beam treatment, the compression stress value decreases to –270 MPa.

Published: January 2023

Researchers working on activity-based mathematics teaching suggest that the materials deeply shape the design and implementations. Despite this effect, empirical knowledge about how teachers approach the materials in their activity selection, and which features of the materials are decisive in their preferences is quite limited. Hence this study aims to designate material features determinant in teachers’ mathematical activity preferences. This research was designed as a multiple case study and was conducted with three secondary school mathematics teachers. During the data collection process, six consecutive semi-structured interviews were conducted with the participants. While structuring the interview process, multiple activities were prepared with different materials to serve the same gain. The data were analyzed by thematic analysis method. The analyses yielded five distinct features that accounted for teachers’ selection and preferences of mathematical activities with regard to materials: serving to the mathematical gains, functionality, accessibility, being proficient in use and student familiarity. The findings showed that teachers' activity preferences had a complex structure and pointed out that instructional decisions were not only shaped on a pedagogical basis and were not only concerned with students' mathematical development. Based on the evaluations of the teachers, it was concluded that the predictions about the affordances and constraints of the materials were decisive in the activity selection.

Purpose: Creation of a device and a new methodology for registering an electrocardiogram that does not require fixation of dogs and impose electrodes.

Materials and methods. Two groups have formed that included clinically healthy 12 dogs of small breeds with a weight category of 10 kg, age restrictions were from 3 to 5 years. Electrocardiograms were recorded as a standard veterinary electrocardiogram, so on the CONAN hardware and software, using standard I, II, III ECG of lead. Electrodes "Crocodile" were fixed on the skin of the pelvic folds, the skin near the elbow joint. The second stage of the study was based on the creation of a contact platform capable of registering a nervous impulse. The proposed methodology for registering electrophysiological activity of the heart is based on the creation of mycal electrodes that can perceive indications in the position of the studied animal standing, excluding a stressful effect, lowering the degree of excitation. The third stage of the study was to register an electrocardiogram through a contact site, followed by assessment and comparison with classical methods.

Results. In the testimony of atrial and ventricular complexes, when using both methods, there were no differences. The amplitude is preserved, the distance between the intervals did not change. During the observation, the lack of pronounced excitement in dogs was revealed when using the simulated site, which, in turn, facilitates the interpretation procedure. The observation revealed a reduction in the time spent on research when using an experimental methodology.

Scientific bottom-trawl surveys are ecological observation programs conducted along continental shelves and slopes of seas and oceans that sample marine communities associated with the seafloor. These surveys report taxa occurrence, abundance and/or weight in space and time, and contribute to fisheries management as well as population and biodiversity research. Bottom-trawl surveys are conducted all over the world and represent a unique opportunity to understand ocean biogeography, macroecology, and global change. However, combining these data together for cross-ecosystem analyses remains challenging. Here, we present an integrated dataset of 29 publicly available bottom-trawl surveys conducted in national waters of 18 countries that are standardized and pre-processed, covering a total of 2,170 sampled fish taxa and 216,548 hauls collected from 1963 to 2021. We describe the processing steps to create the dataset, flags, and standardization methods that we developed to assist users in conducting spatio-temporal analyses with stable regional survey footprints. The aim of this dataset is to support research, marine conservation, and management in the context of global change.

The practice of clinical research is strictly regulated by law. During submission and review processes, compliance of such research with the laws enforced in the country where it was conducted is not always correctly filled in by the authors or verified by the editors. Here we review 456 studies published by the IHU Méditerranée Infection (Marseille, France) and identify a range of issues with the stated authorization of the research, ethically and potentially legally. Of these, 248 were conducted with the same ethics committee reference, even though the subjects, samples and countries were different. Thirty-nine did not even contain a reference to the ethics committee while they contain research on human beings. With this example, we call for stricter control by publishers of the regulatory documentation related to clinical research during the publication process.

Background: With the exponential growth of published systematic reviews (SR) and meta-analyses (MA), there is a high potential for duplication of work and compromising quality. The national institute for health research (NIHR) recommend registration of SR and MA, which can reduce research waste and increase transparency and research quality. This study aimed to investigate the rate of protocol registration and its association with methodological and reporting quality.Methods: We searched SR and MA indexed in PubMed, EMABSE, Scopus and CINAHL databases until March 16, 2021. All SR and MA in medicine and health science fields associated with Ethiopia irrespective of the place of publication, authors' affiliation and design were included. Data on the background, methodological, and reporting characteristics were extracted. We applied Chi-Square or Fisher’s Exact test for categorical variables and Kruskal–Wallis test for continuous variables at alpha level 0.05 to examine association. All analyses were done using R 4.1.3 for macOS.Results: From the total of 349 SR and MA included, 100 (28.65%) registered their protocol. Significantly large proportion of SR and MA with registered protocol reported/conducted last search date (71.0%, p<0.05), duplicate screening (72.0%, p<0.005), duplicate data extraction (83.0%, p<0.005) and duplicate quality assessment (84.0%, p<0.005), and search within two years of publication (78.0%, p<0.05). Additionally, significantly large proportion of SR and MA with registered protocol used Joanna Briggs Institute's quality assessment tool (58.0%, p<0.05) and used Egger's test (89%, p<0.05) to assess publication bias. Moreover, SR and MA with registered protocol were less frequently cited (median = 3.50, p <0.001) and included a smaller number of authors (median = 4.00, p=0.007) than those without registered protocol.Conclusions: Nearly one-third of published SR and MA in medicine and health sciences fields in Ethiopia registered their protocol. SR and MA with registered protocol showed better methodological and reporting quality compared to those without registered protocol, but not for all quality criteria. To improve rate of prospective registration and ensure quality of SR and MA in medicine and health science fields, researchers should be trained in all aspects of SR and MA, and journals, funding agencies, governments and universities should encourage registration of SR and MA as an important indicator of transparency in research.
A predictive nose: Olfactory identification is more reliant than visual identification on predictive object cues

Identifying objects in the environment is one of the most important features of our senses. Toward this goal, predictions are made from known environmental regularities. It is unknown whether different sensory systems may rely differently on cues for prediction and evaluation. Olfaction, the sense of smell, provides a means to test this hypothesis. People are often unable to identify odor stimuli based on scent alone, and cues from vision and audition are often needed. We tested whether olfactory (relative to visual) identification is especially dependent on source-based predictive cues. Participants listened to word cues (object-based, e.g. “lilac”, and category-based, e.g. “flower”), and then quickly determined whether a visual or olfactory target stimulus matched or did not match the word cue. As predicted, we found that the greatest response time differences between matching and non-matching trials occurred when the word cue was object-based and the target was olfactory. This interaction effect disappeared when participants were cued with category-based words (“fruit” or “flower”). A follow-up fMRI experiment revealed an increased involvement of the auditory cortex in anticipation of olfactory relative to visual objects. Furthermore, olfactory error signals activated a transmodal cortical network involving primary olfactory and visual cortices, as well as the anterior cingulate cortex. Our results suggest that olfactory identification may be especially reliant on predictive object cues and involve a vast, sensory-specific cortical error detection system. These results provide new insights into the organisation of sensory-cognitive hierarchies in the human brain.
