The Implementation of Micro-Credentials in Formal and Informal Learning: A Systematic Literature Review
Authors: Rajabalee Yousra Banoor
Published: December 2023

When educational institutions across the globe closed because of the COVID-19 crisis, they rapidly had recourse to emergency remote teaching, online learning, and self-paced training. Such an unprecedented situation accelerated the movement and uptake on courses from online platforms such as Coursera, Udemy, etc. As such, modular learning was seen as a way for learners and professionals to keep on upskilling and reskilling themselves both in academic and professional areas. The recognition of the knowledge acquired, and competencies demonstrated by learners, via a new credentialing system, termed as micro-credentials, is seen as a novel, but ambitious approach that is being portrayed as a highly probable future of education systems. However, several research studies have been conducted in this area with little breakthrough or widescale implementation that has led to substantive changes in existing educational systems and models. This paper presents a systematic literature analysis to understand how micro-credentials concept has so far been implemented in educational contexts, its potential to be recognized as transferable credits in formal higher education and the technologies being implemented to store, stack and manage micro-credentials. The data collection process consisted of selecting articles published in the past ten years. The results show that although there is a growing interest in this research area, there is significant divide between applications and recognition of micro-credentials. Hence, this paper reports a summary of prior research conducted and help in identifying the gaps in research studies with respect to the implementation of micro-credential in formal and informal learning.

Authors: Ji Ce , Cao Chunhong , Geng Rong , Zhang Siyu
Published: December 2023

As a teaching model based on learning transfer theory and constructivist education ideology, the problem driven teaching model is an effective method to combine knowledge inheritance and knowledge reconstruction to cultivate innovative talents. Under the traditional teaching model, schools often only focus on achievements and achievements in the cultivation of graduate students, while ignoring the cultivation of their own innovative and practical abilities in the scientific research process. After realizing the drawbacks of this traditional teaching model, this article applies the problem-driven teaching model to the course “Signal Detection and Estimation Theory”, and hopes to strengthen the problem awareness and practical ability of graduate students in scientific research and learning throughout the entire process of cultivating graduate students, so as to cultivate their ability to discover, analyze, and solve problems, This is the key to cultivating students’ innovative research and professional practical abilities. Under this teaching method, object-oriented autonomous learning has been achieved, further stimulating the innovative consciousness and spirit of graduate students.

Authors: Han Chenshun , Yang Xiaodong , Song Jianwei
Published: December 2023

This paper elaborates on a systematic study on teaching mode of Fundamentals of Mechanical Manufacture course for students majoring in Materials Science. Based on education conception of students-centered, the teaching mode of integrating quality education, knowledge impartment, and ability cultivation is expounded. According to the current situation and existing problems, teaching research focuses on how to inspire the enthusiasm and initiative of students to promote students’ knowledge construction and develop their thoughts and comprehensive abilities. Studies on improving the quality of teachers, optimizing the content of this course and exploring diversified teaching methods such as blended teaching methods and multi-element examination mode are discussed. Changing from the old teaching concepts, the teaching and learning combination mode can stimulate students’ desire for knowledge and learning enthusiasm, and advocate learning autonomy, cooperation, and explore ways of learning. The teaching practice proves that the reform of the teaching pattern improves the teaching quality, broadens the breadth and depth of the course, and favors improving students’ comprehensive quality and ability. It is worthy of continuing to do further research, application and promotion.

Published: December 2023

Immunoglobulin G4-related disease (IgG4-RD) is a multi-organ condition that infrequently exhibits neurological involvement. Here, we describe a case of IgG4-related hypertrophic pachymeningitis with multiple lower cranial nerve palsies. A 65-year-old man presented with a 5-month history of hoarseness and dysphagia. A neurologic examination revealed multiple lower cranial nerve palsies. Brain magnetic resonance imaging indicated diffuse dural involvement along the left tentorium and temporal fossa. Serum IgG and IgG4 levels were found to be elevated. Ethmoid polyp biopsy revealed chronic inflammation with moderate lymphoplasmacytic and some eosinophilic infiltration. Up to 60 IgG4-positive cells were observed per high-power field, and the measured IgG4/IgG ratio was approximately 10% to 20%. Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography indicated abnormally high FDG uptake in the left posterior fossa, tentorium, and left temporal fossa, with additional involvement of the lung, iliac artery, and renal artery. Based on these findings, we diagnosed the patient with IgG4-related hypertrophic pachymeningitis and successfully treated the condition with steroids and rituximab. IgG4-RD should be differentiated from distinct conditions presenting with multiple cranial nerve palsies accompanied by pachymeningitis.

Authors: Iturriza Ana , Urquidi Manuel , Serrate Liliana
Published: December 2023

En respuesta al cambio climático, un número creciente de países y organizaciones internacionales han asumido compromisos para descarbonizar sus economías, estableciendo metas y estrategias concretas. Estos compromisos, reflejados en las Contribuciones Determinadas a Nivel Nacional (CDN o NDCs en inglés), implican una seria responsabilidad para los países en términos de cumplir con las metas establecidas. Dado que se trata de compromisos a nivel nacional, la probabilidad de que se materialicen tales cambios es considerablemente alta, destacando la importancia de analizar su repercusión en el empleo. En este documento, se lleva a cabo un análisis del impacto en el empleo en tres sectores económicos, subrayando el potencial de creación de empleos verdes en los sectores energético, de transporte y agrícola de Ecuador mediante la implementación de prácticas sostenibles asociadas a estos NDC. Los hallazgos proporcionan ideas para los formuladores de políticas, empresas y demás partes interesadas que buscan impulsar una transición hacia una economía más respetuosa con el medio ambiente e inclusiva desde una perspectiva social.
Gender Inequality in Latin America and the Caribbean
Authors: Berniell Inés , Fernández Raquel , Krutikova Sonya
Published: December 2023

This chapter examines gender inequality, focusing on two critical spheres in which gender inequality is generated: education and work. The objective is to provide a current snapshot of gender inequality across key indicators as well as a dynamic perspective that highlights successes and failures. Facilitating a cross-country comparison as well by grouping countries within Latin America by their level of economics development and drawing comparisons with countries outside the region. Finally, it reflect on differences in the ways that gender inequalities play out across different socio-economic groups, particularly those that highlight other sources of inequality. The second part of the chapter focuses on the worksphere. Here it document significant improvements in female labor force participation over the last 20 years, especially among the least-educated women (those with incomplete secondary education). However, progress has not been equal across all the countries in the region the pace of improvement in this dimension has been slowest in the least economically developed countries. These are also the countries where a significant proportion of the adult working population, especially among men, continue to hold highly conservative norms about women's participation in work.
Opting Out from Public Services and the Social Contract in Latin America
Authors: De la O Ana , Rossel Cecilia , Manzi Pilar
Published: December 2023

The seemingly upward trend in opting out from public services and the segregation of income groups in public and private education and health systems has raised concerns about the future of an already fragmented social contract in Latin America. In this chapter, we examine the evolution of the use of private education and private health insurance in selected countries during the first two decades of the 2000s. We also examine the socio-demographic correlates of the decision to opt out, and the association it has with attitudes that are relevant to understand the foundations of the social contract in the region. Overall, the evidence suggests that scholars concerns about the fragility of the social contract are justified, but with some nuances. Wealthy households are mostly opting out of the public education system, and the middle-class is split with a substantial proportion of households opting for private schools. On the other hand, opting out from public health is only prevalent among wealthy households, and even within that group the share of households who are paying for a private health insurance is much smaller than the share of households who opt for private education. For both policy domains, however, we find that people who use private services have worse evaluations of public services, express less support for the public provision of those services, and more generally, are less supportive of redistribution compared to people inside the public systems. We discuss the implications of these descriptive statistics for the sustainability of the public provision of services and the social contract.
Nudging the Trendsetters: Increasing Second-dose HPV Vaccination in Bogota, Colombia
Authors: Martínez Villarreal Déborah , Díaz Lina M. , Maldonado Stanislao
Published: December 2023

This study investigates the effectiveness of dynamic norm nudges in promoting second-dose HPV vaccinations among trendsetters--parents who initiated the first-dose HPV vaccine for their daughters between 2017-2020. Utilizing administrative data from Bogota's Secretariat of Health in a field experiment, we measure the impact of various norm nudges, including trending, qualitative, and quantitative dynamic norms, on actual vaccination rates. Contrary to our hypothesis, dynamic norms alone fail to influence second-dose HPV vaccination rates for these trendsetters. However, the study reveals a 5.22 percent increase attributed to injunctive norms, representing a substantial 34 percent boost compared to the control groups 15.2 percent average. These findings underscore the importance of tailoring nudge strategies to the unique characteristics and preferences of the target population. This research significantly advances our understanding of norm-based interventions' efficacy in influencing minority behaviors, offering valuable insights for developing targeted and impactful public health strategies.
Optimal Age-based Policies for Pandemics: An Economic Analysis of Covid-19 and Beyond
Authors: Brotherhood Luiz , Kircher Philipp , Santos Cezar , Tertilt Michèle
Published: December 2023

This paper investigates the importance of the age composition for pandemic policy design. To do so, it introduces an economic framework with age heterogeneity, individual choice, and incomplete information, emphasizing the value of testing. Calibrating the model to the US Covid-19 pandemic reveals an 80% reduction in death toll due to voluntary actions and the lockdown implemented in the United States. The optimal lockdown, however, is more stringent than what was implemented in the United States. Moreover, the social planner follows an asymmetric approach by locking down the young relatively more than the old. We underscore the importance of testing, showing its impact on reduced deaths, lower economic costs and laxer lockdown. We use the framework to provide systematic insights into pandemics caused by different viruses (among others the Spanish flu), and underline the influence of economic conditions on optimal policies.
Los procesos comunicativos en la vida de un espacio para los muertos. El panteón del Saucito de San Luis Potosí, México
Authors: Pérez Flores José Luis , Ramos Armando Reyna
Published: December 2023

En este artículo analizamos el cementerio del Saucito de San Luis Potosí, México, con una perspectiva novedosa. Los trabajos dedicados a este lugar generalmente estudian la historia del sitio, así como la relevancia de los personajes ilustres que yacen aquí. Sin dejar de lado estos aportes, nos proponemos a discutir los procesos de apropiación contemporánea por parte de los habitantes de la ciudad de San Luis Potosí. Para lograr este propósito, asumiremos que tanto la traza urbana del cementerio, así como sus tumbas y monumentos se comunican mediante lo visual, por lo que, en primer lugar, presentamos la teoría de la imagen expuesta por Hans Belting, sus agenciamientos en la sociedad por parte de Alfred Gell y las consecuencias de su movilidad, vistas por Freedberg; en segundo lugar, acudimos al análisis del espacio público del reciento a través de la interpretación de Henri Lefebvre; y en tercer lugar, señalamos al espacio y la imagen como parte de la teoría general de la comunicación de Martín Serrano. En todo el desarrollo, la imagen fotográfica tiene un papel fundamental, pues forma parte de la argumentación para explicar los procesos que permiten que los vivos se sientan vinculados no sólo con sus antepasados (reales e imaginarios), sino también con el espacio que los alberga trasmutando la muerte individual en vida generacional.
Filhos e Comunicantes
Authors: Silva Leicy Francisca da
Published: December 2023

No Brasil, entre as décadas de 1930 e 1940, foram produzidos e divulgados discursos voltados para a assistência de um grupo formado por crianças e jovens, e legislações que determinavam o Preventório/Educandário como a instituição com esse fim. Nosso objetivo nesse artigo é observar nessa legislação como esse grupo é definido, questionando inclusive a utilização da expressão “filhos de hansenianos” e congêneres nesses documentos. A construção do estigma, analisada por Erving Goffman, é nossa base conceitual em acordo com estudos relacionados à construção da infância e à história das doenças. Nosso percurso metodológico se fez a partir da análise de fontes como: Guia de Encaminhamento médico ao Preventório; o Regulamento de Saúde Pública de Goiás (1932); o Regulamento dos Preventórios para Filhos de Lázaros, Instalados no Brasil; e a monografia intitulada Organização e funcionamento de Preventório. São as seguintes nossas questões: o uso de expressões relacionando as crianças atendidas nos Preventórios à enfermidade, presente na legislação relativa à organização do preventório/educandário, e à profilaxia e ao controle da enfermidade, pode ser percebido como um dos elementos constituidores do estigma? O uso das expressões “filhas de hansenianos” levou a uma interpretação restrita da população atendida nessa instituição? De nossa análise resulta a compreensão de que o público atendido nessas instituições deve ser considerado a partir da sua relação de proximidade com o lar, ambiente familiar estendido, e não especificamente por serem filhos/filhas de enfermos isolados. E que o uso destas expressões contribui no processo de elaboração do estigma.

JOGOS E BRINCADEIRAS NO 1º ANO DO ENSINO FUNDAMENTAL: UMA ANÁLISE A PARTIR DA ANTECIPAÇÃO DO INGRESSO PARA 6 ANOS
Authors: Brigido Procópio Miriã , Volpato Gildo
Published: December 2023

Esta pesquisa visou compreender a percepção das professoras sobre a antecipação do ingresso das crianças ao Ensino Fundamental, ocorrida após a aprovação da Lei nº 11.274/2006, iniciando aos 6 anos de idade, e como os jogos e brincadeiras são contemplados nesse contexto em sala de aula. Foi realizada entrevista com 5 professoras, pedagogas que atuam no 1º Ano do Ensino Fundamental, sendo uma de escola particular e quatro de escolas da rede pública, localizadas no município de Criciúma/SC. A abordagem foi qualitativa, para a qual a coleta de dados se deu por meio de entrevista semiestruturada e, na interpretação de dados, foram utilizados os princípios da análise de conteúdo de Bardin (2011). O estudo evidenciou que a antecipação das crianças ao 1º Ano do Ensino Fundamental não foi vista de forma positiva pelas professoras, sobretudo porque não houve formação para dar mais segurança ao fazerem essa transição. Alegam que as crianças chegam imaturas, conhecem pouco as letras do alfabeto, querem apenas brincar, possuem pouca coordenação motora fina, falta apoio dos pais, demonstrando que esperavam receber as crianças com os mesmos conhecimentos e habilidades daquelas com 7 anos de idade. Os jogos e brincadeiras têm espaços e tempo esporádicos, são utilizados de forma aleatória, pois há indicativos de que não constam no planejamento como atividades programadas que auxiliam no processo ensino-aprendizagem.

Domino of cards: contributions of a game in the perspective of problem resolution to mathematical learning process
Abstract
This paper is an excerpt of a master degree research, already concluded. The investigation, which has a qualitative character, had the general aim of investigating which mathematical abilities of the Number thematic unit can be developed with children of the first grade of elementary school by means of pedagogical proposals with card games in a problem solving resolution approach. In order to achieve it, three types of card games were selected which had as a common thread the “moments of a game” suggested by Grando (2004), adapted: familiarization with the game and first turns, researcher’s oral intervention during the turns, record of the game and game with competence. All those moments were filmed, photographed, and registered in the researcher’s registration book to be analyzed. For this paper, just one of the games was selected: “domino of cards” in order to present it in the perspective of problem resolution and its contributions for the mathematical learning process observed in a first grade class of elementary school. Based on this game analysis, it was possible to understand the contributions of its use as a teaching methodological support, and the teacher had a clear proactive interventional role for the development of the expected mathematical abilities.

Authors: Silva Ana Paula Fernandes Nóbrega da , Cavalcanti Eduardo Luiz Dias
Published: December 2023

Este trabalho é parte de uma pesquisa de mestrado e apresenta contribuições da ludicidade para trabalhar a educação ambiental crítica (EAC). Aliar tarefas lúdicas à EAC pode despertar maior interesse, estimular a participação ativa e promover reflexões sobre atitudes cotidianas que englobam aspectos sociais, culturais e econômicos. O objetivo deste trabalho foi promover reflexões sobre esses aspectos que envolvem a temática do desperdício de alimentos, por meio de atividades lúdicas. Para tanto, foi proposto a estudantes do ensino médio uma tarefa-prova que fazia parte de uma gincana: ir a um comércio alimentício da cidade, pesquisar alimentos que, pelo aspecto físico, provavelmente seriam descartados, entregar uma receita pronta com o alimento citado e preparar um vídeo com suas percepções. O trabalho tem caráter qualitativo, o qual analisou os dados coletados, transcritos e categorizados em relação ao desperdício, ao valor monetário atribuído à aparência, ao senso de responsabilidade e às reflexões geradas. Notou-se que o uso da ludicidade para abordar a EAC é uma metodologia eficaz, pois despertou motivação no cumprimento das atividades propostas, promoveu reflexões e possíveis mudanças de comportamento.
Ludic activities and critical environmental education: a reflection on food waste
Abstract
This work is part of a master's research and presents contributions of ludicity to work on critical environmental education (educação ambiental crítica [EAC]). Combining playful tasks with EAC can arouse greater interest, encourage active participation, and promote reflections on everyday attitudes, which encompass social, cultural, and economic aspects. To this end, high school students were proposed a task-test, which is part of a gymkhana, in which they would go to a food trade in the city, research foods that, due to their physical appearance, would probably be discarded, prepare a video with their perceptions, and deliver a ready-made recipe with the food mentioned in the video. The work has a qualitative character collected, transcribed and categorized, which analyzed the data in relation to waste, the monetary value attributed to appearance, the sense of responsibility, and the reflections generated. It was noted that the use of playfulness to approach the EAC is an effective methodology, as it aroused motivation in fulfilling the proposed activities, promoted reflections, and possible changes in behavior.
Self-employment in UK law
Authors: Barnard Catherine , Georgiou Despoina
Published: December 2023

The United Kingdom has noted a rapid increase in the number of self-employed persons in the last forty years. This has prompted a return to the debate on the regulation of this category of workers. What are the key characteristics of the self-employed? Are they covered by labour law and social security regulations? This chapter answers these questions by looking at the legal framework applicable to the self-employed in the UK. In section 2, the author characterizes the main tendencies regarding self-employed activity in the United Kingdom as presented in a report of the Office of National Statistics for 2020. In sections 3 and 4, she analyses the definition and the legal framework that guarantee protection applicable to the self-employed. The author places particular emphasis on the tri-partite character of the British legal system in individual employment law, which includes certain categories of self-employed in the British definition of worker. Finally, section 5 is devoted to the ever more popular phenomenon of “bogus self-employment” and the legal mechanisms designed to combat it.

Published: December 2023

The Egyptian Mongoose (Herpestes ichneumon Linnaeus, 1758) is one of the most occurring carnivores in Palestine. The current study, which is a part of a big project dealing with wildlife (fauna and flora), aims at providing a modest background on the occurrence, ecology and risks of the Egyptian Mongoose in the Gaza Strip. Direct field observations and meetings and discussions with local people including wildlife hunters were major tools to satisfy the purpose of the study, which lasted 12 years (2007 - 2018). Visits to zoological gardens and animal trade markets were carried out as well. The Egyptian Mongoose occurs in most of the ecosystems of the Gaza Strip that are far away from the populated areas; especially the wadis, Al-Mawasi ecosystem, and the eastern belt of the Gaza Strip. A total number of 30 live and 11 dead specimens were recorded through field surveys. The Egyptian Mongoose was by far, the commonest zoo carnivore, where 33 specimens were encountered at Gaza zoological gardens. Two separate specimens were exhibited for sale at Al-Yarmouk Market in Gaza City. The Egyptian Mongoose is common in swampy habitats of the Gaza Strip, and its occurrence in the sand dune ecosystem seemed to be intermittent. The animal has a wide range of wild preys including small mammals, birds, reptiles and amphibians and insects prevailing within its home range. The animal is well known for its attacks to poultries, and as a result, it was frequently poisoned or killed by farmers and local people. Many minor threats were found to face the species in the Gaza Strip. Finally, the role of the Egyptian Mongoose in controlling the populations of environmental pests, including venomous snakes and commensal rodents should be valued, and as a result, the Palestinian wildlife should be protected and conserved in a sustainable fashion.
Saltbush Irrigation with Treated Wastewater
Authors: Paneque Manuel
Published: December 2023

Saltbush grow in arid and semi-arid climates in the south as well as in the north hemisphere and shapes adapted population to different environmental conditions along with distribution. Nevertheless, there is not enough information available that allows to enhance its productive potential in abiotic stressed conditions. In this research it was determined the effect of the treated waste-water irrigation and the incorporation of organic amendment in the substrate in the development of the ecotypes 607 and 693 of Atriplex nummularia and in the ecotype 610 of Atriplex canescens. Treated waste-water irrigation stimulated the natural increase and the accumulation of biomass in the ecotypes 607 and 693 of A. nummularia and it was inhibited in the ecotype 610 of A. canescens, even though in no case was statistically significant. The incorporation of organic amendment into the substrate had a negative effect in the development of different ecotypes. Plants in enriched substrate with organic amendment and irrigated with treated wastewater showed the same behavior than irrigation plants only with treated wastewater. In all the cases, the ecotype 610 of A. canescens, showed a greater sensitivity to treatments. Results indicate that response of genus Atriplex to irrigation with treated wastewater and the incorporation to organic amendment in the substrate is dependent ecotype.
Agriculture, Grains and Beef Production: Remedies for Food Insecurity and the Ecological Footprint When the Cataclysm Comes?
Authors: L Kick Edward
Published: December 2023

Recently the World Bank and United Nations have predicted a cataclysm of overpopulation that will lead to global starvation (and environmental collapse) in the next ten to thirty years. Recommendations are broadly made that food insecurity can be resolved through substantially increased industrial agricultural production of cattle (for edible beef) and grains for undernourished populations. We test these assertions with data from the Food and Agricultural Organization (FAO). We focus on the world system with attention to the poor periphery of that whole. Structural Equation Modeling is our technique of choice for examining key causes among the 87 countries best suited to the regression equations derived. Others with missing data or having “outlier” status remain for a study of “maverick” cases. Results suggest that the past reports of the World Bank and United Nations are likely to be incorrect. The findings here are in line with our previous work and the very recent and revised opinions of the world’s two great global organizations.
Assessment of the Physicochemical and Microbiological Quality of Sachet Water Sold in Kumbotso LGA, Kano State, Nigeria
Authors: M Mohammed
Published: December 2023

The rise in number of sachet water producers in Kano state calls for continuous and vigorous surveillance of the quality of water consumed by the populace to ensure compliance with the WHO and NAFDAC standards for such products. This study assessed the quality of sixteen brands of sachet water sold in Kumbotso LGA of Kano State, Nigeria. Physical assay, physico-chemical, heavy metal contents and microbiological quality assessments of the water samples were carried out. Not all the water samples examined contained any information on their manufacturing and/or expiry dates. The pH, temperature, conductivity and total dissolved solids (TDS) of all the sachet water brands conformed to the WHO standards. All the five heavy metals (arsenic, lead, iron, copper and zinc) analyzed are observed to be within the safety limits recommended by WHO, however Coliforms and some other pathogenic bacteria were detected in 31% of the sachet water brands; leading to the conclusion that 69% of the sachet water sold in Kumbotso LGA of Kano State is safe for human consumption.

Authors: Solís-Ramos Laura Yesenia
Published: December 2023

The hygroscopic balance of castor bean seeds (Ricinus communis L.) assists the proper handling of the product to preserve its water content at the levels recommended for safe storage. The objective of this work was to determine the water adsorption isotherms of castor bean seeds (EVF103 and EVF106) to obtain information on the amount of water that this product adsorb at temperatures of 10, 20, 30, 40oC and water activities between 0.20 and 0.89, as well as adjusting different mathematical models to the experimental data. To obtain the hygroscopic equilibrium, the indirect static method was used, using Hygropalm Model Aw 1 equipment, analyzing castor bean seeds of the genotypes EVF103 and EVF106. The Copace model (for the EVF103) and Modified Oswin model (for the EVF106), according to the statistical parameters and Akaike’s information criterion (AIC) and Schwarz’s bayesian information criterion (BIC) information criteria, represent the hygroscopicity of castor bean seeds in the temperature range of 10 to 40oC. In a same water activity, the water content of the castor bean seeds of the genotypes EVF103 and EVF106 reduces with increasing temperature.

Authors: Acciaro Marco
Published: December 2023

The work aims to fill the knowledge gap on performance and meat quality of “Agnello di Sardegna” PGI light lambs. To this end fourteen male lambs, homogeneous for age and litter size and consisting of seven pure Sarda (S X S) and seven crossbred Ile de France x Sarda (IF X S) lambs were compared for growth rate, dressing-out percent, chemical composition, fatty acids (FA) composition of Longissimus lumborum muscle and some nutritional indexes. Lambs suckled and followed their mothers at pasture until slaughtering at17±3 kg Live Weight and 50±1 days old, (means±s.d). The SXS lambs showed higher content of some healthy fatty acids (EPA) and better values of some nutritional indexes (Thrombogenic and Ipo-ipercholesterolemic index). The effect of litter size was more pronounced than sire effect, affecting both chemical and FA composition of light lambs. The single lambs showed higher branched chain fatty acids, linoleic and linolenic acid, CLA and other healthy fatty acids (DPA, DHA, omega 3 polyunsatured fatty acids) content. Overall, the value of nutritional indexes highlighted the high nutritional quality of light lamb meat. The results do not seem to justify the use of specialized meat breed as Ile de France for light lamb production, the short period between birth and slaughter not allowing the crossbred lambs to show their greater potential for muscle development. The high CLA content together with fatty acids considered beneficial for consumer health (DPA, DHA) in meat of single light lambs is a result to take into account in a meat production system aimed at high quality.
Forest Management as a Component of Ungulate Management to Avoid Game Damage

Forest management system as a component of ungulate pest management. Wild ungulates are an important site factor in forests and landscapes. Impacts of ungulates on forest vegetation and the effect of hunting systems are often investigated and discussed. In contrast, the impact of silvicultural systems on forest damage by ungulates is much less conscious. Therefore, in a long-term research program in Central Europe since the 1990ies two questions were investigated additionally, (i) in which way can forest management systems and landscape structures influence the interactions between ungulates and forest vegetation, and (ii) how can silvicultural practices modify the susceptibility of forests to damage by ungulates. The results showed a strong impact of these factors on the emergence of game damage to forests. Factors that are often underestimated in practice. Recommendations for a coordinated management of different land users to avoid ungulate damage to forest vegetation and to preserve biodiversity were made.

Coffee is one of the most consumed beverages in the world, it has a high added value, and the manufacturing process must be taken care of. New coffee post-harvest technologies dispense concrete base systems and reduce defects of traditional drying. This study analyzed the effects of new drying units with static dryers that work with dehydrated air to produce gourmet coffees. The results showed that an air dehydrator can dry coffee pods with an initial moisture content of 52% to 10% in just 3.2 days. The conclusion was that the dried coffee fruits in the concrete bases lose more quality than the dried coffee in new drying units.

Penelitian ini bertujuan untuk mengetahui kandungan kimia dan sedimentasi urin kucing lokal yang hidup bebas berkeliaran di sekitar Kota Denpasar. Sampel yang digunakan adalah urin kucing yang diambil secara acak dan digunakan sebagai latihan bedah cystocentesis dan kateterisasi. Sebanyak delapan ekor kucing jantan dan delapan ekor kucing betina dewasa sampel urinnya diambil dan dimasukkan ke dalam pot steril, lalu dilakukan pengamatan kimia urin dengan pemeriksaan menggunakan dipstick yang memiliki 10 paramater yaitu leukosit, nitrit, urobilinogen, protein, pH, darah, berat jenis (spesific grafity), keton, bilirubin, dan glukosa. Pemeriksaan dipstik dilakukan dengan cara mencelupkan stik ke dalam masing-masing sampel selama 0,5-1,0 menit hingga seluruh parameter terendam, kemudian diangkat dan ditaruh di media datar yang telah dilapisi tissue lalu ditunggu selama tiga menit hingga parameter berubah warna dan diulangi sebanyak tiga kali. Setelah dilakukan pemeriksaan kimia urin menggunakan dipstick, sampel urin kucing di dalam tabung reaksi diendapkan dengan menunggu dan mendiamkan sampel urin tersebut semalaman dalam tabung yang diposisikan secara tegak lurus. Setelah 20 jam diendapkan, kemudia endapan tersebut diambil dan diletakkan di atas objek glass lalu diperiksa menggunakan mikroskop cahaya dengan perbesaran 400 kali. Penelitian ini termasuk ke dalam penelitian observasional yang menekankan pada pengamatan kuantitas/ jumlah zat dan sedimentasi yang terdapat didalam sampel urin kucing. Dari 16 sampel yang diperiksa, semua sampel negatif terhadap pemeriksaan leukosit, nitri, urobilinogen, dan darah. Protein ditemukan pada 75% sampel kucing, Glukosa 1+ ditemukan pada 6,25%, dan masing-masing 100% positif pada pemeriksaan ketone dan bilirubin. Sedangkan rata-rata berat jenis urin kucing bernilai 1,022 dan pH urin bernilai 6,75. Selanjutnya dari hasil pemeriksaan sedimentasi urin, 11 sampel ditemukannya crystal dan casts urin yang terdiri dari Calcium oxalate monohydrate, triple phosphate, Magnesium Amonium Phosphate, Kumpulan Kristal Struvite, dan Lipid droplets. Dari pemeriksaan sampel tidak ada perbedaan signifikan antara kucing jantan dan betina.
Makna Qalb dalam Al-Qur’an Berbasis Tafsir Mafatih al-Ghaib dan Neurosains

Penelitian ini bertujuan untuk mengetahui makna qalb. Qalb dilafazkan 168 kali di dalam Al-Qur’an. Hingga saat ini, masih terdapat perdebatan makna dari kata tersebut, apakah merujuk pada jantung atau otak. Arti kata qalb yang sering dirujuk sebagai hati, menjadikan maka qalb cenderung ditujukan kepada jantung. Metode penelitian yang digunakan adalah studi pustaka. Hasil penelitian menunjukkan bahwa qalb merujuk kepada otak sebagai organ, dan segala fungsi atau sifat yang melekat pada ayat berupa berpikir, merasakan, dan sebagainya adalah kognisi dari otak manusia. Dengan demikian qalb bukanlah berarti hati atau jantung, melainkan otak yang ada di dalam kepala manusia.
Función ideológica de la écfrasis en la representación del clérigo letrado y su relación con el poder monárquico en el Libro de Alexandre
Authors: Calarco Gabriel Alejandro
Published: December 2023

El presente trabajo se encuentra dedicado al estudio de la écfrasis y su función ideológica en el Libro de Alexandre, un poema clerical castellano que es la primera de las obras del estilo poético que la crítica moderna identifica como “mester de clerecía’’. Nuestro objetivo será analizar y poner en relación los diferentes pasajes del poema que pueden ser considerados como écfrasis, tanto aquellos dedicados a descripciones de obras de arte, como los que tienen por objeto lugares o acciones con un fuerte componente visual. Particularmente, nos detendremos en la figura de Apeles, artista letrado al servicio de Alejandro, y en sus obras, que son el objeto de algunas de las descripciones ecfrásticas más extensas y elaboradas del poema. Con este fin, consideraremos la hipótesis del reflejo entre Apeles y el autor anónimo del poema castellano, propuesta por Amaia Arizaleta y retomada en varios estudios posteriores, para analizar lo que las écfrasis del Libro de Alexandre pueden decirnos sobre la concepción del arte y del artista del clérigo que lo compuso, y sobre el público al que habría estado dirigido el poema.
Evento climático extremo e vulnerabilidades

Analisamos a comunicação, no Twitter, do desastre ocorrido no interior de São Paulo, no Carnaval de 2023, que matou 65 pessoas e desalojou 2000, causado por uma soma de eventos climáticos extremos e vulnerabilidades sociais e ambientais. Em 24 horas, houve a maior chuva da história das medições do país, que atingiu a região de São Sebastião - SP. Metodologicamente, analisamos o que três veículos de mídia e quatro instituições de governo publicaram em seus perfis de Twitter na semana da crise entre os alertas e o ápice do desastre. Foram analisados 235 tweets e neles foi aplicado um protocolo de análise. Filiamo-nos conceitualmente a uma perspectiva social e histórica sobre os desastres e aos aportes da Comunicação de Riscos de Desastres, da Comunicação de Crise e do Ciclo de Atenção aos problemas públicos. Consideramos que o Twitter traz lógicas próprias das redes, mas também é um espaço de disputas discursivas sociais que pode se constituir em sistema de alerta. Concluímos que, considerando mensagens de alerta das instituições de governo, os cidadãos só dispuseram de avisos técnicos e ficaram à mercê de suas próprias decisões. Quanto aos tweets da mídia, a cobertura foi intensiva no clímax do evento sem preocupação em enfatizar alertas ou protocolos de ação.
imaginação como elemento lúdico do imaginário
Authors: Freitas Camila
Published: December 2023

Este artigo se dedica a uma discussão teórica em relação à imaginação como um elemento lúdico intrínseco ao imaginário. Para isso, explora os conceitos de símbolo, imagem e imaginação, situando o ato imaginativo em um contexto mais amplo e destacando suas dimensões poéticas e fantásticas. Além disso, reflete sobre a importância da atividade lúdica nos estudos do imaginário, enfatizando a ligação do jogo e da criatividade à imaginação, promovendo a exploração de novas perspectivas, a experimentação de diferentes realidades e a expansão de mundos ficcionais. Essa abordagem não só enriquece o entendimento lúdico do imaginário, mas ressalta seu papel fundamental na promoção de uma retórica focada na brincadeira, fornecendo novos significados à vida humana.

Les prairies et pâturages représentent 25 % des terres émergées. Une exploitation efficiente et durable de ces ressources fourragères nécessite notamment une gestion adaptée des plantes envahissantes très souvent responsables de leur dégradation. Cette gestion nécessite de disposer de connaissances sur leur comportement et pour cela une bonne identification. Le portail collaboratif Wiktrop aide à identifier les adventices et facilite le partage et la diffusion des connaissances sur les adventices tropicales et leur gestion entre acteurs de terrain et scientifiques. Ces connaissances permettent d’améliorer les pratiques de contrôle des adventices dans l’ensemble des régions tropicales et méditerranéennes. La contribution des utilisateurs est un facteur important de la qualité et de l’étendue des informations mises à disposition. Ce portail évoluera prochainement avec l’intégration des plantes fourragères et des plantes de services tropicales.
