Extorsión, (trans)feminicidio y trabajo sexual trans en un contexto (pos)pandemia: Alternativas de reparación en el caso de Jéssica Martínez
Authors: Gutiérrez Guevara Pedro Andrés
Published: July 2024

La pandemia de COVID-19 agudizó las condiciones materiales de vida de las mujeres trans en Ecuador, especialmente las trabajadoras sexuales. El aumento del proxenetismo y la extorsión, la venta forzosa de drogas y el pago de vacunas al crimen organizado se han tomado esquinas, plazas, barrios y cuerpos de mujeres trans, hasta llegar al punto máximo de violencia: el (trans)feminicidio. Este texto brinda datos sobre el aumento de homicidios intencionales y su relación con el aumento de muertes violentas a mujeres trans y personas LGBTIQ+. Finalmente, se toma como estudio de caso el transfeminicidio de Jéssica Martínez, activista trabajadora sexual trans, para revelar la victimización secundaria y la falta de debida diligencia en las investigaciones penales en estos casos, así como para plantear las alternativas que tienen sus compañeras trabajadoras sexuales a la hora de imaginar una reparación colectiva.
Significados sobre reparación integral en víctimas del conflicto armado colombiano en Ecuador
Authors: Moreno Núñez Paola Natalia
Published: July 2024

Este trabajo ensaya reflexiones sobre los significados que construyen, acerca de la reparación integral, las personas víctimas del conflicto armado colombiano que viven en Ecuador, desde sus percepciones sobre dignidad y proyecto de vida. Parte de la premisa de que la Ley 1448 sobre Víctimas y Restitución de Tierras de Colombia establece una asimetría entre las víctimas que se encuentran en territorio colombiano y las personas que, siendo sobrevivientes del conflicto, están en otros países, en tanto acceso a los derechos a la verdad, a la justicia y a la reparación con garantías de no repetición, así como a las medidas de atención establecidas en esta norma. Desde esta perspectiva, se configuran condiciones adversas para que exista una restauración de la dignidad y de los proyectos de vida de esta población. Esto se hace más patente cuando las condiciones de vida en Ecuador excluyen y marginan a las personas colombianas en situación de refugio. De lo anterior se desprende la urgencia de analizar medidas de reparación que no estén necesariamente ancladas a las respuestas estatales, que por su naturaleza y competencias institucionales están circunscritas al territorio colombiano. Se plantea la necesidad de que las medidas de reparación tengan presentes las expectativas de permanencia en Ecuador de las personas colombianas víctimas del conflicto que buscan reconstruir en este país sus proyectos de vida.

Authors: Bangun Nimpan , Simanjuntak Benri
Published: July 2024

Magnesium silicate 75, magnesium silicate 90, and magnesium silicate MgO have been synthesized to increase the concentration of vitamin E from candlenut oil. The reaction of MgO and SiO2 synthesizes the adsorbent magnesium silicate—X H2O by hydrothermal method. The magnesium silicate obtained was characterized by BET, showing the pore size of the three different types of adsorbents, namely magnesium silicate 75 (6.118 nm), magnesium silicate 90 (6.248 nm), and magnesium silicate MgO (3.2238 nm). The adsorbent is used to increase the concentration of vitamin E in candlenut oil. Pecan oil is dissolved with n-hexane in a ratio of 1: 1 in a column containing the adsorbent. After the n-hexane descends from the column tool, vacuum to remove the solvent. Then the results are collected into vials. Then vitamin E levels wer measured by HPLC using standard Tocopherol and tocotrienol. The results of the HPLC test obtained a comparison of the three types of adsorbents' ability to increase levels of vitamin E from candlenut oil, where the adsorbent of magnesium silicate MgO can only increase vitamin E levels which were 429 ppm to 248.72 ppm (0.57 times enriched). In contrast, the magnesium silicate adsorbents 75 and 90 can increase vitamin E levels from 429 ppm to 733.73 ppm (1. 71 times improved) and 855.97 ppm (1.99 times enriched).

With the adoption of the Principles and Guidelines for the Social Dimension, the ministers of the European Higher Education Area have committed to "strengthening the social dimension of higher education and fostering equity and inclusion to reflect the diversity of society", an endeavour that involves creating higher education systems that are inclusive and supportive of the access, participation, progress, and completion of all students, with a special emphasis on those who are vulnerable, disadvantaged, or underrepresented. The EUROSTUDENT survey covers many aspects of student diversity, including gender, age, students with children, migration background, and disability. This chapter presents data on these aspects, as well as students' experiences of discrimination based on various aspects of diversity. The data presented in this chapter underscore that student populations across Europe vary significantly along these dimensions.
Students’ time budget
Authors: Menz Cordelia , Mandl Sylvia
Published: July 2024

Studying often goes along with more freedom of choices and expectations of being an independent learner compared to being in secondary school. Starting higher education also offers a variety of new opportunities and students need to juggle many responsibilities. Hence, one of the many tasks of students is to organise their daily schedule. On average across all EUROSTUDENT countries, students spend 48 hours per week on study-related activities and work, with most of the time (18 hours) spent on personal study time, closely followed by taught studies (16 hours) and work (14 hours). These numbers vary greatly between countries and students. Therefore, this chapter will focus on the time budget of students with different characteristics, for example, full-time/part-time students, (non)-working students, different types of higher education institutions, various fields of study, and types of study programmes. Taking a closer look at working students, for instance, it can be reported that working while studying affects both students' free time and their study time. Overall, data presented in this chapter give insights into students' schedules including a cross-country perspective.
Students’ employment and internships
Authors: Mandl Sylvia , Menz Cordelia
Published: July 2024

Paid jobs can help students to meet their expenses, to participate in activities with fellow students, to be accepted and to belong to higher status groups. However, in contrast to these positive aspects, working while studying can be detrimental to academic performance, lead to longer duration of study, and increase the risk of dropping out of higher education. This chapter therefore not only shows that most students have paid jobs, but also analyses the extent of students' work and the motivations behind it. It also shows how students' jobs are characterised, e.g. whether the work content is related to the study field, and which differences exist between groups of students. In light of the ongoing discussions at EU level on the financial remuneration of internships, the chapter also takes a closer look at the characteristics of students' internships.

The UK Breast Cancer in Pregnancy (UKBCiP) Study. Incidence, diagnosis, management and short-term outcomes of breast cancer first diagnosed during pregnancy in the United Kingdom: A population-based descriptive study
Authors: Hardy Claudia , Brand Andrew , Jones Julie , Knight Marian , Banfield Philip
Published: July 2024

Background The incidence of breast cancer first arising during pregnancy has been estimated in several countries to be 2.4–7.8/100,000 births, but has not been established in the United Kingdom (UK). We aimed to estimate the incidence of breast cancer diagnosed during pregnancy in the UK and to describe its management and short-term outcomes for mothers and babies. Methods This population-based descriptive study used the UK Obstetric Surveillance System (UKOSS). Cases were prospectively identified through monthly UKOSS mailings to all UK consultant-led maternity units. All cases of breast cancer diagnosed first during pregnancy, between October 1, 2015, and September 30, 2017, were eligible, with 84 confirmed cases analyzed. Women with breast cancer diagnosed before pregnancy or with a recurrence were excluded. The primary outcomes were the incidence of breast cancer first diagnosed during pregnancy, maternal mortality, severe maternal morbidity, perinatal mortality, and severe neonatal morbidity. Results The incidence was 5.4/100,000 maternities (95% CI 4.37, 6.70). Nine women (11%) had undergone in vitro fertilization (IVF), compared with an estimated 2.6% IVF pregnancies in the UK at that time. During pregnancy, 30 women (36%) underwent surgery and 37 women (44%) received chemotherapy. Three women had major maternal morbidity during pregnancy. Two women died and two perinatal deaths occurred. Conclusions The incidence of breast cancer arising in pregnancy in the UK is similar to that reported in other countries. The higher proportion of IVF pregnancies among women diagnosed with breast cancer during pregnancy needs further investigation, as it may not be entirely explained by relatively advanced maternal age. With caveats, the management followed that outside pregnancy, but there was considerable variation in practice. Although short-term outcomes were generally good for mothers and babies, a larger prospective study is required. It is often possible to avoid exposing the baby to iatrogenic prematurity.
The Effect of Nonlinear Sloshing Response of Water on Seismic Behavior of Reinforced Concrete Elevated Water Tanks
Authors: Köksal Olgun , Karaca Zeki , Türkeli Erdem
Published: July 2024

In this study, the fluid-structure interactive behavior by using the Westergaard approach and the Smoothed Particle Hydrodynamics (SPH) method of a 1000 m3 reinforced concrete (RC) elevated water tank under different seismic activities i.e., Kocaeli, Van, Kahramanmaraş and Kobe earthquakes was investigated. In the SPH method, the resulting hydrodynamic pressures were applied to the interior of the wall of the structure as an external force which is made as mass additions to the tank walls in Westergaard approach. With the help of software developed, the load carrying system of the elevated water tank was modeled using the MATLAB Partial Differential Equation Toolbox (PDE) software, based on the finite element method, and its verification was made by comparing with ANSYS software model. Dynamic condensation method was used to perform time history analyses for the cited earthquakes. The time-dependent solutions of partial differential equations are solved with the help of ODE45 functions based on Runge-Kutta method, by arranging the equation of motion in state-space format. The cited tank was analyzed linearly under different seismic activities for empty, half-filled (50%) and full-filled (100%) cases and the obtained results were compared with each other. It has been concluded that considering nonlinear behavior of the fluid during the earthquake with the SPH method provided consistency with the real behavior of RC elevated water tanks and gave more realistic results than the traditional Westergaard approach.

Left Handed Metamaterials in Microstrip Patch Antenna Design: Miniaturization, Multiband Operation, and Improved Performance
Authors: Shimu Nusrat Jahan , Kar Pankaj Chandra , Islam Md Ariful , Ahmed Anis
Published: July 2024

The exotic electromagnetic properties of metamaterials (MTM) can be utilized to meet the increasing demand for smaller, lighter, and more compact multiband antennas. As the resonant frequency is dependent on the aperture parameters of the antenna, metamaterials allow for the miniaturization and performance enhancement of antennas. In this paper, two novel designs of metamaterial loaded microstrip patch antennas are proposed. The first structure emphasizes the miniaturization of patch antennas with performance improvements. The second one deals with the multiband operation of metamaterial loaded antennas with wider bandwidth and improved performance. Compared to the conventional microstrip patch antenna (MPA), the proposed metamaterial loaded antenna has reduced the size by 75%, and antenna characteristics have also improved significantly. The proposed metamaterial antenna resonates at 2.45 GHz, the return loss is -26 dB, and a gain of 5.28 dB is achieved. The multiband antenna can be realized by etching different numbers of complementary split ring resonators in the ground plane. The model proposed with three split ring resonators (SRR) at the ground plane shows quad band operations and can be used in S-band and C-band simultaneously. The quad-band antenna resonates at 3.04 GHz, 3.42 GHz, 5.35 GHz, and 6.08 GHz with bandwidths of 78 MHz, 93 MHz, 167 MHz, and 185 MHz, respectively. The antennas are designed on an FR-4 substrate with a permittivity of 4.3. Nicolson-Ross-Weir (NRW) method has been employed for the extraction and verification of the metamaterial properties of the unit cells. Due to its ability to capture more energy, the reported antenna can be used as a wireless device as well as an RF energy harvesting device.

Mining Weighted Patterns from Time Series Databases Based on Sliding Window
Authors: Rizvee Redwan Ahmed , Shahin Md Shahadat Hossain , Ahmed Chowdhury Farhan , Leung Carson K
Published: July 2024

Data mining has traditionally relied heavily on sliding window-based challenges, which has sparked a variety of studies. For each new window in time series mining, current literature mandates the rebuilding of the underlying structure, Suffix Tree - A trie-based structure representing all the suffixes of a string. However, reconstruction struggles when the window is wide or when sliding happens frequently. As a result, we provide a new technique Dynamic Tree-Based Approach to handle Sliding Windows (DTSW) in time series in this study that dynamically changes the representative suffix tree structure rather than reconstructing it after every alteration or sliding. In addition, we also put forth a different approach to the issue of extracting weighted periodic patterns from time series. To prevent testing pointless patterns, existing studies mostly rely on the weight of the database's highest-weighted item. However, these methods continue to examine numerous patterns. These methods still examine numerous patterns to see whether they can be candidates. Our proposed measure Maximum Possible Weighted Support (MPWS) accelerates the candidate generation process by removing numerous unnecessary patterns in advance. The novelty of MPWS is it considers the maximum weighted average over the maximum weighted item extension by enforcing more constraints. The usefulness of our two techniques in handling sliding windows and trimming redundant candidate patterns is demonstrated by experimental results using a variety of real-world datasets. Our experiments state that our dynamic handling technique significantly improves runtime than the reconstruction in a dynamic sliding window-based environment with simultaneous insertion and deletion actions and MPWS reduces the number of tested patterns resulting in lesser mining time in weighted time series pattern mining.

Applying Sequential Correlation to Identify Order Dependent Activity Pairs
Authors: Arefin Md Fahim , Islam Maliha Tashfia , Ahmed Chowdhury Farhan
Published: July 2024

Mining sequential patterns has been one of the most useful fields in data mining. For example, one recent application of sequential pattern mining is analyzing logs of activity to predict and recognize activities. This is used for both daily life activities and virtual activities.  However, only patterns are not always enough to represent the truly interesting information to the end user, especially when the support threshold is low and the number of frequent patterns is huge. A correlation measure is necessary to decipher the relationship between the logged activities. This data is generally collected as a sequence and there is no widely popular correlation measure for elements in sequential patterns. Therefore, we define Sequential Correlation, a novel correlation measure, for discovering important knowledge in sequential patterns and the corresponding full method, SCMine, to classify patterns based on the measure. We employed the measure to establish either a unidirectional or bidirectional association among the activities within a sequence and subsequently classified the sequences based on order dependency. Moreover, an efficient implementation approach for our measure is also discussed. Our performance study shows that, a significant number of activity patterns can be pruned when degree of order among the activities is important. So, it is also useful for classifying or pruning less significant activity patterns from a vast number of frequent sequential patterns.

Cuyo objetivo es determinar los roedores sinantrópicos capturados en los sitios peridomiciliarios y del campo, como animales modelos experimentales para pruebas biológicas. Estos roedores se adaptaron bajo estrictos protocolos de manejo en la domesticación, reproducción y crianza, además de la salubridad. Durante el estudio se especificó a los roedores sinantrópicos Rattus norvegicus y Rattus. Los primeros roedores sinantrópicos en incorporarse en los ambientes del bioterio perecieron en el cautiverio. En el año 2001, se incorporó para la domesticación una camada de 8 crías de ratas pardas (Rattus norvegicus), con 15 días de nacidas. Durante el periodo de 2004, se integró a los roedores sinantrópicos del campo, ratas negras (Rattus rattus). En el año 2010 se optimizó la reproducción y crianza de los roedores.
