Background

The economic burden of rare diseases on health systems is still not widely measured, with the generation of accurate information about the costs with medical care for subjects with rare diseases being crucial when defining health policies. Duchenne Muscular Dystrophy (DMD) is the most common form of muscular dystrophy, with new technologies recently being studied for its management. Information about the costs related to the disease in Latin America is scarce, and the objective of this study is to evaluate the annual hospital, home care and transportation costs per patient with DMD treatment in Brazil.

Results

Data from 27 patients were included, the median annual cost per patient was R$ 17,121 (IQR R$ 6,786; 25,621). Home care expenditures accounted for 92% of the total costs, followed by hospital costs (6%) and transportation costs (2%). Medications and loss of family, and patient’s productivity are among the most representative consumption items. When disease worsening due to loss of the ability to walk was incorporated to the analysis, it was shown that wheelchair users account for an incremental cost of 23% compared with non-wheelchair users.

Conclusions

This is an original study in Latin America to measure DMD costs using the micro-costing technique. Generating accurate information about costs is crucial to provide health managers with information that could help establish more sustainable policies when deciding upon rare diseases in emerging countries.

Published: June 2023

The impacts of Geo-hazard events are main obstacles to the use of land in numerous arid and semi-arid provinces of the World. Furthermore, the various activities of industrial communities, such as Egypt's 10th Ramadan Industrial Region (10th RIR), are the most dangerous examples of waste's impact on soil, surface water, and groundwater. The current study uses image processing and GIS tools to identify, delineate, monitor, and assess some of the environmental hazards caused by both human and natural activities in the 10th RIR. The findings revealed that there are rapid changes in land cover, which could be attributed to both anthropogenic and natural activities. Furthermore, the results revealed that waterlogging, salt-affected soils, water pollution, and flash floods were the most serious environmental threats to the 10th RIR. The obtained geo-hazard map showed that the 10th RIR has high flash flood hazards zones that are geospatially distributed in the southern parts of the Wadi Gafra basin and the western parts of 10th of Ramadan City. Furthermore, salinized soil zones are viewed as geospatially restricted zone in the eastern portion of 10th of Ramadan City and/or near the oxidation ponds. Additionally, vast areas of highly contaminated groundwater exist beneath industrial, urban, and oxidation pond zones. The current work provides decision-makers with numerous mitigation measures and recommendations required to minimize the impacts of geo-environmental hazards endangering the 10th RIR.

Published: June 2023

Introduction

Iodine is a crucial trace element for thyroid hormone synthesis. All age groups are affected by iodine deficiency disorders (IDD), especially pregnant women, young women, and children. Iodine deficiency disorder has been recognized as a serious public health issue in Ethiopia. Therefore, the aim of the current study was to assess the availability of iodized salt and associated factors at the household (HH) level in the Farta district, northwest, Ethiopia.

Methods

A community-based cross-sectional study was conducted involving 704 participants in Farta District, Northwest Ethiopia, between February and March 2021. A multi-stage sampling technique was employed to recruit participants. Data were collected using pretested and structured questionnaires administered by face-to-face interviewers. The data were entered into Epi-data version 4.6 software and exported into Stata version 14 for the purpose of analysis. Both bivariable and multivariable logistic regression analyses were used to identify factors associated with the availability of iodized salt. Statistical significance was declared at a p-value ≤ 0.05 with a corresponding 95% confidence interval.

Results

The availability of adequately iodized salt in the study area was 26.6% (CI = 23.8%, 29.4%) of households. Good knowledge about iodine deficiency disorder (IDD) and iodized salt (AOR = 3.85, 95% CI: 3.65, 6.11); short-term storage of salt at the HH [AOR = 2.76, 95% CI: 1.98, 3.23); and stored in covered containers (AOR = 1.57, 95% CI: 1.11, 1.78) were significantly associated with the outcome variable.

Conclusion

The availability of adequate iodized salt at the HH level was far below the WHO target (more than 90%) in the study area. Knowledge about IDD and iodized salt, stored in covered containers, and short-term storage of salt at the HH were significantly associated with the availability of iodized salt. Hence, at the household level, increasing awareness and disseminating information about the benefits of using iodized salt could be effective. Moreover, education about the proper storage and handling of iodized salt, as well as the recommended storage duration of salt in the home, should be provided as part of our community outreach programs.
Game-based assessment framework for virtual reality, augmented reality and digital game-based learning
Authors: Udeozor Chioma , Chan Philippe , Russo Abegão Fernando , Glassey Jarka
Published: June 2023

Immersive learning technologies such as virtual reality (VR), augmented reality (AR) and educational digital games offer many benefits to teaching and learning. With their potential to immerse learners in realistic environments and facilitate higher-order cognitive learning, these technologies could be used to complement current classroom pedagogical practices. However, given that these learning environments differ from conventional classroom learning activities, current assessment practices may be insufficient for assessing learning in immersive environments. This paper develops the concept of a game-based assessment framework (GBAF) for educators interested in the assessment of learning in digital games, VR or AR. Importantly, this paper also presents the application of the framework to the design and implementation of assessments for a VR game during the game design phase. Grounded in the principles of Constructive Alignment and the Evidence-Centred Design (ECD) framework, this assessment framework describes the steps to consider for assessments and outlines the components that must be aligned for the design of assessments. To illustrate the application of the GBAF to the design of assessments for immersive learning environments, a stepwise design of assessments for a VR game is presented. The results of the outcome of the assessment of laboratory health and safety competencies of six engineering students is also presented. The GBAF offers simple and useful guidelines for the design of assessments around game tasks. It could serve as a structured basis for educators and researchers to design assessments to measure lower and higher-order cognitive learning in complex immersive environments.

Background

It was aimed to investigate the psychological effects of the Coronavirus disease 2019 (COVID-19) pandemic on children and adolescents. The effects of disease process on development of psychiatric disorders, the course of pre-existing disorders, and peer relationships of children who have had COVID-19 infection were evaluated. Fifty three patients (28 girls and 25 boys) who were aged 12 ± 2.64 years and diagnosed with COVID-19 infection within the last 3–9 months, were randomly selected and included. Sociodemographic form, Beck Depression Inventory/Children’s Depression Scale, Symptom Checklist 90-Revised were given to the participants, and a semi-structured interview was used to establish psychiatric disorders before and after COVID-19 infection. Parents were asked to fill in Conner’s Rating Scale-Parents and Behavioral Rating Inventory of Executive Function.

Results

Compared to pre-pandemic, duration of physical activity and time spent with peers were decreased, while screen exposure was found to be increased. Subclinical psychiatric symptoms were exacerbated after infection and most affected area was eating problems with loss of appetite and weight.

Conclusions

In conclusion, our data showed that COVID-19 is associated with an increase in psychiatric disorders among children and adolescents, and further studies are needed in a larger population to investigate the causes and consequences of these effects.
Sound levels and its effect on physiology of low birth weight newborns in a special care newborn unit — a prospective observational study
Authors: Das Saptasikha , Chakraborty Pinaki , Bora Reeta , Chakraborty Priyanko
Published: June 2023

Background

From quiet environment in uterus, neonates in special care newborn units (SCNU) get exposed to a stressful technology-driven environment. Noise level in neonatal intensive care units (NICU) depends on social and psychological realm of people working there. In NICU, an hourly Leq (median equivalent continuous sound level) of sound should be 45 dB, Lmax, 60 dB, and L10 not exceeding 50 dB (AAP, 2007). Noise level in SCNUs of northeast India has not been studied.

Aim

Create awareness among health workers (HW) regarding noise.

Objective

To study (a) noise level in special care newborn unit and (b) its effect on neonatal physiology.

Methodology

A prospective observational study was conducted in a teaching hospital in northeast India for 1 month. After IEC approval, ambient sound levels in intensive care unit (ICU) (levels 2 & 3) and kangaroo mother care (KMC) area were measured using inVH by Bosch Engineering Solution (android app) in 3 shifts. Forty hemodynamically stable quiet low birth weight neonates (level 2: 16, level 3: 14, KMC: 10) were evaluated for heart rate and respiratory rate at same time. Acutely sick neonates were excluded. Statistical analysis was done using SPSS.

Results

Average sound at 10 am, 5 pm, and 11 pm in level 2 was 70.2 (+ 3.78) dB, 71.9 (+ 4.21) dB, and 54.6 (+ 5.38) dB; in level 3: 66.4 (+ 3.71) dB, 64.9 (+ 3.88) dB, and 63.5 (+ 2.52) dB; and KMC: 55.06 (+ 5), 54.66 (+ 5.38), and 47.7 (+ 5.1) dB (p = 0.0052). Of included neonates, mean birthweight in intensive vs KMC area was 1.378 (+ 0.017) vs 1.337 (+ 0.02) kg (p = 0.1) and gestational age 35.45 (+ 0.25) weeks and 34.8 (+ 0.91) weeks (p = 0.2). The mean neonatal heart rate and respiratory rates in level 2 were 154/min and 44 cycles/min, level 3: 148/min and 47 cycles/min; and KMC: 124/min and 40 cycles/min.

Conclusion

Significant noise pollution is detected in levels 2 and 3 neonatal intensive care units and minimal in kangaroo mother care area. Raised neonatal heart rates and respiratory rates in intensive care units with respect to KMC area may be related to noise. The social and psychological realm of healthcare workers and caregivers needs urgent improvement so as to reduce ambient noise pollution in special care newborn units.

Authors: Jordan Julie-Ann , Shannon Ciaran , Browne Dympna , Carroll Emma , Maguire Jennifer , Kerrigan Keith , Hannan Sinead , McCarthy Thomas , Tully Mark A. , Mulholland Ciaran , Dyer Kevin F. W.
Published: June 2023

Background

Cross-sectional studies have shown that the COVID-19 pandemic has had a significant impact on the mental health of healthcare staff. However, it is less well understood how working over the long term in successive COVID-19 waves affects staff well-being.

Aims

To identify subpopulations within the health and social care staff workforce with differentiated trajectories of mental health symptoms during phases of the COVID-19 pandemic.

Method

The COVID-19 Staff Wellbeing Survey assessed health and social care staff well-being within an area of the UK at four time points, separated by 3-month intervals, spanning November 2020 to August 2021.

Results

Growth mixture models were performed on the depression, anxiety and post-traumatic stress disorder longitudinal data. Two class solutions provided the best fit for all models. The vast majority of the workforce were best represented by the low-symptom class trajectory, where by symptoms were consistently below the clinical cut-off for moderate-to-severe symptoms. A sizable minority (13–16%) were categorised as being in the high-symptom class, a group who had symptom levels in the moderate-to-severe range throughout the peaks and troughs of the pandemic. In the depression, anxiety and post-traumatic stress disorder models, the high-symptom class perceived communication from their organisation to be less effective than the low-symptom class.

Conclusions

This research identified a group of health service staff who reported persistently high mental health symptoms during the pandemic. This group of staff may well have particular needs in terms of the provision of well-being support services.
Beyond the Inner Chambers: Xu Zhaohua and Her Teacher Mao Qiling
Authors: Widmer Ellen
Published: June 2023

Mao Qiling 毛奇齡 (1623–1713) was a celebrated poet, scholar, and official whose life bridged the transition from Ming to Qing. A lesser-known aspect of his life was his interest in and work with women writers, especially the group associated with Shang Jinglan 商景蘭 (1605–1680). In the mid-1670s, Xu Zhaohua 徐昭華 (17th–18th cent.), the daughter of Shang's younger sister Shang Jinghui 商景徽 (17th cent.), became Mao's disciple, one of the most famous. This article sets the Mao-Xu relationship in the context of Mao's other work with women and brings out its special features. After the Mao-Xu relationship became well known, most talented women who sought instruction still chose to work with female teachers, but some pursued the new alternative of working with a talented man.
Where Have All the Guixiu Gone? Chinese “Women of Talent” at the Turn of the Twentieth Century
Authors: Li Xiaorong
Published: June 2023

Guixiu 閨秀 (cultivated gentlewomen of the inner chambers) and cainü 才女 (women of talent) arguably became authorly identities (referring to women writing in classical verse) as women's literary culture took shape in Ming-Qing China. However, the guixiu and cainü were gradually eclipsed by their rising “modern” sisters, xin nüxing 新女性 (new women) and nü zuojia 女作家 (women writers), during the late-Qing reform (1890s) and the early-Republican New Culture movement (1910s–1920s). This study provides a historical investigation into two cases of the literary practice of men and women who carried the legacy of their Ming-Qing predecessors into the Republican era: Wang Wenru 王文濡 (1867–1935) and his Xiangyan zazhi 香艷雜誌 (Xiangyan Magazine, 1914–1916) and Gu Xianrong 顧憲融 (1901–1955), who published the Hongfan jingshe nü dizi ji 紅梵精舍女弟子集 (Collection of Female Disciples from the Abode of Red Brahman, 1928). They reveal the persistence of guixiu culture in a diversified and transformed world of literary production and consumption from the 1910s to the 1920s.

Use of Machine Learning in Volatility: A Review Using K-Means
Authors: Molina Muñoz Jesus Enrique , Castañeda Ricard
Published: June 2023

Recently, the use of machine learning (ML) in scientific disciplines has experienced an unprecedented increase. Finance has not been an exception. Several works have been published in recent years using mltechniques. However, one of the topics with the least number of developed papers is volatility in this context. Nevertheless, the data analyzed here suggest changes regarding this issue. Data obtained from the Web of Science database show that between 2001 and 2010 there were 33 published papers associated with this topic. Surprisingly, between 2019 and 2023, 189 manuscripts have been published related to this topic. The purpose of this work is to review the works related to the applications of ml in volatility. For this, a classification of the main proposals on this topic is proposed following a narrative methodology, accompanied by a statistical and bibliometric analysis in which novel techniques such as K-means were used. The results are suggestive. Although most papers focus on volatility prediction through neural networks and support vector machines, there is a lack of studies related to volatility transmission, calibration of volatility surfaces,and corporate finance. Moreover, the obtained results indicate that there is a gap in the production of worksrelated to these topics in finance and economics specialized journals.
Percepción de consumidores y perspectivas de industrias de alimentos de Cali sobre el uso de bioplástico en sus empaques
Authors: Pinto Torres Camilo Andrés , Cardona Gómez Juanita , Polanco Puerta Manuel Francisco
Published: June 2023

Las tendencias del mercado masivo de alimentos y las exigencias de inocuidad alimentaria han favorecido el uso de empaques plásticos de fuentes fósiles, generando impactos críticos a nivel ambiental, social y económico. Los bioplásticos se presentan como una alternativa más sostenible para sustituir los plásticos de un solo uso. Esta investigación analiza la percepción de los consumidores e industriales frente al uso de bioplástico para los empaques de los alimentos de consumo masivo en la región del norte del departamento del Cauca y sur del Valle del Cauca, en Colombia. Se usa una metodología mixta con información cualitativa y cuantitativa, incluyendo trabajo de campo de observación de empaques en el mercado, encuestas a consumidores de la región caracterizadas por género, estrato socioeconómico y edad, y entrevistas a ejecutivos de industrias de alimentos y empresas de plásticos. La disposición final de los bioplásticos tiene una estructura de separación en la fuente y aprovechamiento similar a los derivados del petróleo, su uso adiciona un nuevo material que, con la estructura actual, se sumaría a cerrar su ciclo en rellenos sanitarios y fuentes hídricas, sin generar impactos favorables. Las ventajas de los bioplásticos son su posibilidad de compostar y su origen de fuentes renovables.

La segunda vuelta de las elecciones presidenciales del 19 de junio de 2022 opuso a dos personalidades alejadas de las élites tradicionales del país y de los grandes partidos políticos. Por un lado, Gustavo Petro era líder de una izquierda que nunca había llegado a las más altas funciones en Colombia y parecía condenada al eterno ejercicio de la oposición, por el otro, Rodolfo Hernández era una figura nueva en la política nacional que saltó de la alcaldía de Bucaramanga a la candidatura presidencial con base en un discurso de rechazo a la clase política en general. El perfil inhabitual de los dos contrincantes suscitó muchos comentarios sobre el auge del populismo en el país sobre un trasfondo de crisis de la representación política y de fuerte conflictividad social. Este libro se propone discutir a través de contribuciones diversas qué puede enseñarnos el concepto de populismo sobre el nuevo escenario político que dibujaba este enfrentamiento electoral.

Authors: Gholami Amin , Sun Kaizhao , Zhang Shixuan , Sun Xu Andy
Published: June 2023

When optimizing electric power system operational decisions, it is of great importance to prevent potential failures in both the system operation and the optimization algorithm. In “An Alternating Direction Method of Multipliers-Based Distributed Optimization Method for Solving Security-Constrained Alternating Current Optimal Power Flow,” Gholami, Sun, Zhang, and Sun propose a novel two-level algorithm that (1) effectively prevents power system operational failures through consideration of impactful contingencies and (2) guarantees convergence when parallelized on a computing cluster with multiple nodes. Extensive numerical experiments suggest that the proposed algorithm is able to provide high-quality feasible solutions under the time limit of 10–45 minutes for various synthetic and industrial networks with up to 30,000 buses and 22,000 contingencies, comparable with the size of the U.S. power grid.

Development and labour resistance: a class composition perspective on import-substitution industrialisation in Chile and Argentina
Authors: Fishwick Adam
Published: June 2023

Research on labour and development has demonstrated the significance, both analytically and politically, of labour for understanding the political economy of development. Analyses of labour regimes highlight the central role of reorganised workplaces and changing labour processes in value chains across the global economy. Research in global labour studies illustrates the ways in which concepts and theorisations of labour struggles emanating from the Global North struggle to capture the dynamics of labour conflict in the Global South and their wider impacts. This article argues that the revival of autonomist ‘class composition’ approaches can advance a labour perspective on development by shedding light on the importance of labour’s defeats when mapping the contours of the political economy of development. This approach reveals how what E.P. Thompson called the ‘dead ends’ of labour history are essential to understanding the grounds upon which state and capital reorganise to contain workers’ demands and struggles, thereby setting new conditions for these struggles to re-emerge. Drawing on insights from the early work of Antonio Negri, the article will examine how processes of working-class composition and decomposition occurred within the trajectory of import-substitution industrialisation in Chile and Argentina, establishing new labour regimes in its early crises. The article demonstrates this through original archival research using industry journals and publications from the textile industry in Chile and metalworking industry in Argentina.
Label-free quantification of protein binding to lipid vesicles using transparent waveguide evanescent-field scattering microscopy with liquid control
Authors: Mapar Mokhtar , Sjöberg Mattias , Zhdanov Vladimir P. , Agnarsson Björn , Höök Fredrik
Published: June 2023

Recent innovations in microscopy techniques are paving the way for label-free studies of single nanoscopic biological entities such as viruses, lipid-nanoparticle drug carriers, and even proteins. One such technique is waveguide evanescent-field microscopy, which offers a relatively simple, yet sensitive, way of achieving label-free light scattering-based imaging of nanoparticles on surfaces. Herein, we extend the application of this technique by incorporating microfluidic liquid control and adapting the design for use with inverted microscopes by fabricating a waveguide on a transparent substrate. We furthermore formulate analytical models describing scattering and fluorescence intensities from single spherical and shell-like objects interacting with evanescent fields. The models are then applied to analyze scattering and fluorescence intensities from adsorbed polystyrene beads and to temporally resolve cholera-toxin B (CTB) binding to individual surface-immobilized glycosphingolipid GM1 containing vesicles. We also propose a self-consistent means to quantify the thickness of the CTB layer, revealing that protein-binding to individual vesicles can be characterized with sub-nm precision in a time-resolved manner.

Published: June 2023

An optical system for the generation of partially coherent beams with genuine cross-spectral density functions from spatially modulated globally incoherent sources is presented. The spatial intensity modulation of the incoherent source is achieved by quasi-planar metasurfaces based on spatial-frequency modulation of binary Bragg surface-relief diffraction gratings. Two types of beams are demonstrated experimentally: (i) azimuthally periodic, radially quasi-periodic beams and (ii) rotationally symmetric Bessel-correlated beams with annular far-zone radiation patterns.
Gender disparity in prestigious speaking roles: A study of 10 years of international conference programming in the field of gambling studies
Authors: Monson Eva , Ng Kimberly , Sibbick Hannah , Berbiche Djamal , Morvannou Adèle
Published: June 2023

The objective of this study was to examine the distribution of prestigious speaking roles by gender at gambling studies conferences to better understand the state of gender representation within the field. Keyword searches were conducted in the fall of 2019. A total of 16 conferences that occurred between 2010–2019 and comprising 882 prestigious speaking opportunities were included. Quantitative analysis (i.e., t-tests, chi-squared posthoc tests) was undertaken to evaluate the representation of women speakers and if proportions were the same across genders for speakers. There were significantly less women than men within prestigious speaking roles at gambling studies conferences with only 30.2% of speakers being women (p < .001). This underrepresentation of women was consistent across conference location, speaker continent, speaker role, time, and across the majority of conferences. Women held prestigious speaking roles less frequently than men (M = 1.48 vs. 1.76; p < .001). A 9 to 1 (p < .001) ratio of men to women was found among top 10 most frequent prestigious speakers. While there was a higher proportion of women than men among student speakers and there was no significant gender disparity among early career researchers, there was a significantly lower proportion of women than men among speakers who hold more senior academic positions. There is an issue of gender disparity in prestigious speaking roles at conferences within the gambling studies field. This study highlights the need to counteract gender disparities and make room for diversity within the field.
Plastomes of Sonchus (Asteraceae) endemic to the Atlantic Madeira archipelago: Genome structure, comparative analysis, and phylogenetic relationships
Authors: Kim Hye-Been , Lee Dong-Geol , Kim Seung-Chul
Published: June 2023

The woody Sonchus alliance, a spectacular example of adaptive radiation with six genera and approximately 31 species, is found exclusively on three Macaronesian Islands (Madeira, Canaries, and Cape Verdes) in the Atlantic Ocean. Four of the Sonchus taxa are restricted to Madeira, including shrubs and small trees at higher elevations (S. fruticosus and S. pinnatus), and caudex perennials in the lower coastal areas (S. ustulatus subsp. maderensis and S. ustulatus subsp. ustulatus). The Madeiran Sonchus stemmed from a single colonization event that originated from the Canaries < 3 million years ago. However, the plastome evolution and species relationships remains insufficiently explored. We therefore assembled and characterized the plastomes of four Sonchus taxa from Madeira and conducted a phylogenomic analysis. We found highly conserved plastome sequences among the taxa, further supporting a single and recent origin. We also found highly conserved plastomes among the cosmopolitan weedy Sonchus, Macaronesian Sonchus in the Atlantic, and Juan Fernández Islands Dendroseris in the Pacific. Furthermore, we identified four mutation hotspot regions (trnK-rps16, petN-psbM, ndhF-Ψycf1, and ycf1) and simple sequence repeat motifs. This study strongly supports the monophyly of Madeiran Sonchus. However, its relationship with the remaining woody Sonchus alliance from the Canary Islands requires further investigation.
La danse du détour: A collaborative arts performance with people touched by Minamata disease

Published: June 2023

In May 2019, a group of dancers, photographers and local participants gathered in Minamata, Japan, a community affected by industrial mercury pollution since the 1950s. Philippe Chéhère, Julie Salgues and the Minamata Dance Collective conducted a series of dance sessions with citizens, students, dancers and people touched by Minamata disease in various places of significance in Minamata and explored the potential of movement and its transformation in people and the environment. Through choreographic poetry, they explored the site and the story of Minamata involving 180 people, using dance as a modality of encounter and dialogue. The ten-day dance project culminated in a participatory performance at Minamata Memorial. This case study documents the process of participatory arts by interweaving history, photographs and participants’ voices.
Editorial

Published: June 2023

This editorial reviews how art as primary evidence can persuade those in other fields outside of applied arts of its profound influence psychologically, culturally, socially and politically. Examples are presented of how art’s inherent value and effect towards instilling deeper meaning, well-being and healthier ways of living, has influenced those who we might conceive of as holding financial power to open doors for funding and accessibility. And yet even after almost eighty years of applied arts and health in institutions across sectors, there are still those who feel that if we do not utilize the language and protocols of science, social science and medicine, then there will be no direct way towards securing funding. This long-standing debate is discussed here with illustrations that challenge this ongoing mythology. It is further emphasized that the samples presented here are the very reason that this journal was established in the first place.

La lucha contra la precariedad laboral pasa por arbitrar una serie de reformas legales que garanticen la estabilidad en el empleo, por lo que -con independencia de la más certera valoración que podamos ofrecer a la luz de los datos reales, próximos y futuros- el refuerzo a la contratación laboral indefinida nos marca el punto de partida desde el que comenzar.

El segundo pilar -a nuestro juicio- que requiere la atención del legislador es la formación, pues solo garantizando esta y no circunscribiéndola a una etapa concreta del devenir vital de la persona, podemos alcanzar esa meta a la que atiende el ser humano de realización profesional.

Partiendo de esos dos sustentos existe, a nuestro modo de ver, una institución que necesariamente tiene que ser repensada a fin de garantizar que se dé cumplimiento a su verdadera esencia. Nos referimos a las becas y, aunque se haya pospuesto la regulación del denominado comúnmente “Estatuto del becario”, nos parece oportuno examinar -a día de hoy- cuáles son los problemas reales que enfrenta esta figura, cómo y cuándo se ha empleado para disfrazar lo que son auténticas relaciones laborales.

Por ello, es nuestra intención realizar un análisis eminentemente casuístico a partir de la doctrina judicial y pronunciamientos del Alto Tribunal para tratar de inferir de aquel las debilidades actuales a las que se enfrenta el becario (o supuesto becario) y cuáles son los derechos/garantías que deberían ser contempladas normativamente.
Conciencia histórica de juventudes mexicanas y su relación con la noción de ciudadanía
Authors: Latapí Escalante Paulina , Rivas Servín Emma Delfina
Published: June 2023

El propósito consistió en dilucidar cómo interviene la interpretación del pasado en las nociones de ciudadanía de jóvenes queretanos en relación con la República Mexicana. Se instrumentó una metodología cuantitativa selectiva (datos del Proyecto Barómetro de las Américas y datos del Proyecto Residente) para interpretarlos cualitativamente. Se expone a) problematización del constructo de ciudadanía en relación con la conciencia y la cultura históricas; b) comparación de datos del Proyecto Residente para Querétaro (Latapí y Rivas, 2021, 2022), aplicado a jóvenes de 16 a 18 años en 2019, con datos nacionales de jóvenes de 18 años del Barómetro de las Américas, 2021; c) resultados que aportan coincidencia en el concepto de ciudadanía despolitizado, estático asociado al derecho legalista, que no se construye en la participación sino en la observancia de normas morales. Ello se asocia a la cultura y conciencia históricas preponderantes.
A imaginação na pesquisa sobre ensino e aprendizagem de história
Authors: Mainardes Waiga Juliano
Published: June 2023

Muitos estudos no âmbito da educação têm refletido sobre a importância da imaginação no processo do aprendizado. Considerando o interesse de levantar a parcela desses estudos que pensam o tema da imaginação a partir dos interesses específicos do ensino-aprendizagem de história, realizou-se no presente artigo, uma revisão bibliográfica de literatura. Buscou-se verificar o que tem sido produzido e quais as lacunas na literatura científica sobre o tema da imaginação no ensino-aprendizagem de história. Os trabalhos identificados permitem perceber que as referências que abordam o tema da imaginação no ensino-aprendizagem de história são escassas e sustentam-se em referenciais antigos, mas unânimes em defender a importância dessa habilidade mental na relação do indivíduo com o conhecimento histórico. Constatou-se também, a necessidade da elaboração de novos estudos que se proponham a contribuir para a distinção entre imaginação no sentido amplo e imaginação histórica.
Nuevas “esquizofrenias” para la Esquizohistoria: la historia divulgada en medios masivos y digitales, y su impacto en las aulas
Authors: Dragowski Andrés
Published: June 2023

Este trabajo tiene como objetivo reflexionar sobre la importancia de la llamada “divulgación de la historia” o “historia de masas” para la discusión de la didáctica especifica de la historia. Se delinean rasgos epistemológicos e historiográficos de dicho fenómeno y se trazan puentes entre este y las problemáticas de la enseñanza de la historia consideradas relevantes por la bibliografía especializada. Se hace hincapié en los interrogantes y problemáticas que ofrece la web 2.0 como paradigma de entorno digital colaborativo y los productos culturales históricos que por ella circulan, y el modo en que estos son consumidos por estudiantes y docentes de Historia. Para este fin, se analiza brevemente el rol de los best-sellers históricos y Wikipedia. En este sentido, se entiende que el rol de la comunicación pública de la Historia, aparece como un producto de amplia resonancia que tendría efectos performativos en cómo se enseña la Historia en las aulas en el marco del entorno digital del siglo XXI.

Authors: Jurado Gonzalo Martín
Published: June 2023

Este trabajo expone algunos resultados de un estudio exploratorio realizado en la Facultad de Humanidades, Artes y Ciencias Sociales de la Universidad Autónoma de Entre Ríos, Paraná. Se analizaron las perspectivas que poseen los estudiantes acerca de diversos temas vinculados a la Historia en materiales para la enseñanza de la disciplina y la Historia Americana Colonial. Además se realizó una comparación entre las concepciones que tenían los estudiantes antes y después del trayecto de la carrera de profesorado en Historia, y en particular por la asignatura Historia Americana II. Esta incluye contenidos desde la invasión al continente americano a finales del siglo XV hasta los procesos de independencia a comienzos del siglo XIX. Los resultados de la investigación posibilitaron observar la alta valoración que otorgan los estudiantes al estudio de la historia. Además, es notable el metaanálisis que pudieron realizar de su formación, que incluye su paso por la escuela secundaria.

The demand for nickel manganese cobalt (NMC)-type batteries is increasing along with the need for global electric vehicles, such as electric cars. Nickel used in the manufacture of NMC batteries is Nickel (II) sulfate hexahydrate (NiSO4.6H2O). Therefore, it is necessary to study how to synthesize nickel sulfate powder from blast furnace ferronickel to provide an alternative source of nickel sulfate and increase the added value of blast furnace ferronickel products. This study aims to analyze the effect of variations in the time difference of stepped filtering sludge on the precipitated filtrate. This study uses a nickel source from the ferronickel derived from the sintering and smelting process using a Mini Blast Furnace to synthesize nickel sulfate. First, the ferronickel was ground and sieved to pass 50 mesh size. Then, the leaching process was performed using a mixture of 120 mL H2SO4 (2M) and 30 mL H2O2 (30%) with a stirring speed of 200 rpm for 6 h for each 2 g ferronickel. Next, the precipitation process was carried out using CaCO3 powder to pH 3.01 at 90 °C. The precipitation solution was held at 90 °C for 24 h, and stepped filtering of the precipitate formed with variations of 2, 4, 6, and 8 h (the total time is kept the same, i.e., 24 h). The crystallization results were then washed and dried at 70 °C for 2 h. Based on X-Ray Fluorescence (XRF), the best results were obtained in stepped filtering variation every 8 h with 50.23% Ni content and 90.5% Ni separation efficiency. Based on XRD, the nickel sulfate powder product has the compound NiSO4.6H2O. In addition, nickel sulfate products also contain CoSO4, one of the compounds needed to manufacture NMC batteries. However, nickel sulfate powder products still contain impurity compounds like FeSO4 and CaSO4.
