CLEANing Cygnus A Deep and Fast with R2D2
Authors: Dabbech Arwa , Aghabiglou Amir , Chu Chung San , Wiaux Yves
Published: May 2024

A novel deep-learning paradigm for synthesis imaging by radio interferometry in astronomy was recently proposed, dubbed “Residual-to-Residual DNN series for high-Dynamic range imaging” (R2D2). In this work, we start by shedding light on R2D2's algorithmic structure, interpreting it as a learned version of CLEAN with minor cycles substituted with a deep neural network (DNN) whose training is iteration-specific. We then proceed with R2D2's first demonstration on real data, for monochromatic intensity imaging of the radio galaxy Cygnus A from S-band observations with the Very Large Array. We show that the modeling power of R2D2's learning approach enables delivering high-precision imaging, superseding the resolution of CLEAN, and matching the precision of modern optimization and plug-and-play algorithms, respectively uSARA and AIRI. Requiring few major-cycle iterations only, R2D2 provides a much faster reconstruction than uSARA and AIRI, known to be highly iterative, and is at least as fast as CLEAN.

Published: May 2024

The genus Oenocarpus Martius, 1823 (Arecaceae) includes five species commonly used in Amazonia, especially for their fruits. Little is known about the cytogenetic characteristics and DNA amounts of these species, except for O. bataua (Martius, 1823). This study characterized and compared the types of interphase nuclei, the chromosome sets, and estimated the nuclear DNA amounts of Oenocarpus bacaba (Martius, 1823), O. bataua, O. distichus (Martius, 1823), O. mapora (H. Karsten, 1857) and O. minor (Martius, 1823). Standard cytogenetic analyses and estimates of the nuclear DNA amount by flow cytometry were carried out. These are the first reports of chromosome numbers and DNA amounts, except for O. bataua, as is the description of the chromatin distribution in interphase nuclei and karyotype for all species. All species presented 2n = 36, confirming the previous report for O. bataua. Differences between karyotype formulas and the positioning of secondary constrictions were observed. There were no significant differences for the nuclear DNA amounts among species. The constancy in chromosome number and variations in karyotype formulas suggest the occurrence of chromosome rearrangement as an important mechanism in Oenocarpus speciation.

In recent years, there has been an increase in the adventive establishment and spread of parasitoid wasps outside of their native range. However, lack of taxonomic tools can hinder the efficient screening of field-collected samples to document the establishment and range expansion of parasitoids on continent-wide geographic scales. Here we report that Leptopilina japonica (Hymenoptera, Figitidae), a parasitoid of the globally invasive fruit pest Drosophila suzukii (Diptera, Drosophilidae), is now widespread in much of North America despite not having been intentionally introduced. Surveys in 2022 using a variety of methods detected L. japonica in 10 of 11 surveyed USA States and one Canadian Province where it was not previously known to occur. In most surveys, L. japonica was the most common species of D. suzukii parasitoid found. The surveys also resulted in the detection of Ganaspis cf. brasiliensis (Hymenoptera, Figitidae), the recently-released biological control agent of D. suzukii, in six USA States where it had not previously been found. These new detections are likely a result of intentional biological control introductions rather than spread of adventive populations. A species-specific multiplex PCR assay was developed as a rapid, accurate and cost-effective method to distinguish L. japonica, G. cf. brasiliensis, the closely-related cosmopolitan parasitoid Leptopilina heterotoma (Hymenoptera, Figitidae) and other native parasitoid species. This dataset and the associated molecular tools will facilitate future studies of the spread and ecological impacts of these introduced parasitoids on multiple continents.

Published: May 2024

Opposition-based learning (OBL) is an optimization method widely applied to algorithms. Through analysis, it has been found that different variants of OBL demonstrate varying performance in solving different problems, which makes it crucial for multiple OBL strategies to co-optimize. Therefore, this study proposed a dynamic allocation of OBL in differential evolution for multi-role individuals. Before the population update in DAODE, individuals in the population played multiple roles and were stored in corresponding archives. Subsequently, different roles received respective rewards through a comprehensive ranking mechanism based on OBL, which assigned an OBL strategy to maintain a balance between exploration and exploitation within the population. In addition, a mutation strategy based on multi-role archives was proposed. Individuals for mutation operations were selected from the archives, thereby influencing the population to evolve toward more promising regions. Experimental results were compared between DAODE and state of the art algorithms on the benchmark suite presented at the 2017 IEEE conference on evolutionary computation (CEC2017). Furthermore, statistical tests were conducted to examine the significance differences between DAODE and the state of the art algorithms. The experimental results indicated that the overall performance of DAODE surpasses all state of the art algorithms on more than half of the test functions. Additionally, the results of statistical tests also demonstrated that DAODE consistently ranked first in comprehensive ranking.

Learning from success in the supervision process
Authors: Videmšek Petra , Fox Joanna
Published: May 2024

Supervision forms an essential component of professional social work practice. It supports the development of the capacity and skills of both students as emerging practitioners and of more experienced social workers. Reflection is a key part of supervision because social work practice is constantly evolving due to rapid change in society. Supervision provides social work practitioners and students with an opportunity to speak openly and honestly about their work, and the everyday feelings and emotions they face whilst in practice. This enables both improvement in practice and prevents the buildup of stress. In this article, we explore different methods of supervision utilised in social work and highlight implementation in Slovenia and England. We developed our own framework of supervision drawing on our knowledge of research from Slovenia and England; moreover, we engaged in informal discussion with colleagues in England, and a more formal process with supervisors in Slovenia, to inform the development of this model. This article thus reports the conceptual findings of a study and introduces our own model of reflective supervision, which is founded on the premise that we learn better from good experiences than from mistakes. We believe that through the proposed format of appreciative practice, we can move from deficit-based practice to strengths-focused practice.

Published: May 2024

In this paper, we investigate the potential of teaching energy-related topics to enhance secondary school students’ future thinking skills, including problem-solving, predicting, and envisioning. A physics enrichment program was conducted using the “Madrasati” digital platform in a semi-experimental design involving two groups of students (experimental and control). Utilizing a pre-post measurement approach, the study employed a novel instrument to assess future thinking across three distinct levels. The analysis, involving ETA squared, Cohen’s effect size, and independent sample t-tests, revealed a significant improvement in future thinking skills for the program group. These findings suggest the potential of incorporating energy-related topics and digital platforms into secondary science curricula to enhance critical thinking skills necessary for addressing future challenges. The study further underscores the potential of digital tools and innovative teaching approaches in optimizing students’ development of future thinking competencies.

Pleomorphic Adenoma - A Case Report on an Abnormal Mass
Authors: Deenadayalan N. , Pandyan Deepak Abraham , Satheesh C. , Aparnaa M. , Harthi G.
Published: May 2024

Rationale:

Pleomorphic adenoma (PA) is the most prevalent salivary gland tumour, accounting for 60%–80% of all benign salivary gland tumours, and frequently affects the parotid gland. Their epithelial and connective tissue origins can explain the ‘pleomorphic’ nature of tumours. This tumour is most common in women between 30 and 50 years.

Patient Concerns:

A 45-year-old female came with the chief complaint of a slow-growing, painless swelling on the left side of her face that had been present for 25 years.

Diagnosis:

PA of the parotid gland was diagnosed using computed tomography and fine-needle aspiration cytology. PA is a slowly progressing, asymptomatic swelling that rarely exceeds 6 cm in its greatest dimension; in our case, it was 13 cm × 10 cm and weighed 5 kg.

Treatment:

The ideal management is the surgical removal of the tumour mass, which was done under general anaesthesia. Early diagnosis and treatment planning was critical. Complete removal of the tumour without remnants is crucial to prevent a recurrence. Total parotidectomy was done in this case.

Outcomes:

There was no evidence of recurrence after comprehensive local surgical resection of the tumour during the follow-up period.

Take-away Lessons:

This case report is significant as it sheds light on the successful treatment approach for a large pleomorphic adenoma. It can provide valuable insights into the management of similar cases, potentially leading to improved patient outcomes and guiding future treatment strategies.

Published: May 2024

ABSTRACT

Background:

Accidental ingestion of foreign bodies in children is critical, as the inability to effectively communicate can potentially lead to devastating consequences. We aimed to determine the epidemiology of foreign body ingestion and variability according to age, gender, type, and location of foreign body, and describe its management.

Aim and Objective:

The aim was to study the various types of foreign body ingestions in children admitted to pediatric surgery and their management.

Materials and Methods:

A retrospective study was conducted from January 2020 to June 2022 on children under the age of 12 years with a confirmed diagnosis of foreign body ingestion. Patients were clinically and radiologically assessed, after which standard protocols were followed wherein patients were followed by either observation or emergent management. Emergent management included removal of the foreign body by either endoscopy or surgery. Comparisons among multiple age groups, gender, type of foreign body, location of foreign body, and their management were analyzed.

Results:

Out of 99 subjects in our study, there were 76 boys and 23 girls. The median age of presentation was 5 years. Most children were asymptomatic at presentation. The most frequently ingested foreign body was a coin in all age groups. The majority of the foreign bodies were suspected to be in the small bowel. The foreign bodies that had crossed the duodenojejunal flexure (n = 74, 74.7%) were managed conservatively with the observation of a variable period of a minimum of 24 h and a maximum of 48 h. 21 cases were managed by endoscopic removal, while three cases required surgical intervention.

Conclusions:

Overall, the most common gastrointestinal foreign body was a coin in all age groups. Button battery is the most worrisome foreign body; however, depending on its position, it can be managed conservatively. Upper GI foreign bodies can be safely removed endoscopically. Parental counseling is very important for the prevention of ingestion of foreign bodies.
Delphi Method Analysis and Consensus of Prevalent Distinctive Practices for Biliary Atresia Management after Kasai Portoenterostomy
Authors: Vutukuru Sravanthi , Solanki Shailesh , Kanojia Ravi Prakash
Published: May 2024

ABSTRACT

Background:

Extrahepatic biliary atresia (BA) is seen in infants, with an incidence of 1 in 15,000 live births. The presentation is progressive jaundice, dark-colored urine, and clay-colored stools. Kasai portoenterostomy (KPE) is the commonly performed surgical procedure in these patients. Postoperatively, phenobarbitone, ursodeoxycholic acid (UDCA), steroids, and other drugs are given to improve bile drainage and prevent inflammation and fibrosis. However, a definitive protocol regarding the need for different drugs, dosage, and duration varies across individual surgeons and centers. No universally accepted protocol exists for postoperative management after KPE.

Aim:

The aim of this study was to know the prevailing postoperative management of BA by subject experts and use the Delphi process to know if the experts want to change their practice based on the results from the survey.

Material and Methods:

A questionnaire was made after discussing with two experts in the field of BA. The questionnaire was mailed to 25 subject experts. The first survey data were analyzed and shared with all responders. In the second survey, change in the management based on the results from the first survey was assessed.

Results:

The Delphi questionnaire was answered by 17 experts. Postoperatively, prophylactic antibiotics are prescribed for 6–12 weeks by around 40% and >12 weeks by 30% of respondents. Phenobarbitone is prescribed for <3 months by nearly 50%. UDCA is prescribed for <3 months, ≤6 months, and 6 months–1 year by 47.1%, 23.5%, and 23.5% responders, respectively. Nearly 50% prescribe steroids (mostly prednisolone), and among them, two-thirds prescribe it for 6–12 weeks. Approximately 60% give antiviral drugs to children who are cytomegalovirus immunoglobulin M positive. In our survey, 50% of experts perform 5–10 KPE per year, and 25% each perform 10–15 and >15 KPE per year. The second survey noted that a significant percentage of responders want to change their practice according to consensus.

Conclusion:

From our Delphi survey, an overview of the postoperative management of BA could be made. However, multicentric studies are required for uniform protocol on the postoperative management of BA.

ABSTRACT

Introduction:

Ladd’s procedure, originally described in 1936 for the treatment of malrotation, does not traditionally include appendectomy as a standard step. We conducted a multinational survey to investigate the current consensus on the role of appendectomy in Ladd’s procedure.

Methodology:

An anonymous online survey was distributed to pediatric surgeons worldwide. The survey collected demographic data and explored surgical preferences related to the management of malrotation. Open-ended questions were used to assess the opinions regarding the necessity of appendectomy, decision-making factors, and complications associated with appendectomy during Ladd’s procedure.

Results:

A total of 343 responses were received from 46 countries. Of the respondents, 319 (93%) were consultants and 24 (7%) were residents/trainees. When asked about the choice between open and laparoscopic Ladd’s procedure, 292 (85%) preferred open surgery. Overall, 184 (53%) respondents favored appendectomy in both open and laparoscopic Ladd’s procedure. Furthermore, 172 (50%) surgeons advocated for appendectomy in all malrotation cases, citing concerns about potential future appendicitis. While differences existed between all comparisons, none of them reached statistical significance. The factors influencing the decision to preserve the appendix included the risk of postoperative complications and the potential future use of the appendix as a surgical conduit. The surgical complications following appendectomy included surgical site infections in 14 (33%) patients, adhesive obstruction in 13 (31%) patients, intrabdominal abscesses in 10 (24%) patients, and fecal fistulas in 5 (12%) patients.

Conclusion:

The majority of surgeons aim to perform appendectomy in all malrotation cases, considering the potential risks and benefits of this approach. These findings offer valuable insights for clinical practice and may inform future guidelines and decision-making algorithms.
Peripheral nerve blocks for analgesia following cesarean delivery A narrative review
Authors: Agarwal Jyotsna , Babuwe-Ngobi Joy , Belani Kumar G. , Malhotra Naveen
Published: May 2024

Spinal and epidural blocks are commonly employed for pain relief during and following cesarean section. Intrathecal morphine (ITM) has been the gold standard for the same for many years. In recent times, many peripheral nerve blocks (PNBs) have been tried for postoperative analgesia following cesarean delivery (PACD). This article has reviewed the common PNBs used for PACD. The role of PNBs along with ITM has been studied and the current best strategy for PACD has also been explored. Currently, Ilio-inguinal nerve and anterior transversus abdominis plane block in conjunction with intrathecal morphine have been found to be the most effective strategy, providing lower rest pain at 6 hours as compared to ITM alone. In patients not receiving intrathecal morphine, recommended PNBs are lateral transversus abdominis plane block, single shot local anesthetic wound infiltration, or continuous wound infiltration with catheter below rectus fascia. PNBs are recommended for PACD. They have an opioid-sparing effect and are devoid of adverse effects associated with central neuraxial blocks such as hypotension, bradycardia, and urine retention. However, caution must be observed with PNBs for possible local anesthetic toxicity due to the large volumes of drug required.

Published: May 2024

Background and Aims:

Enhanced recovery after cesarean (ERAC) is an interdisciplinary approach to improve patient outcomes following cesarean section. ERAC’s execution must be constantly evaluated. Thus, we aimed to analyze parameters associated with ERAC adoption for clinical care in this expanded systematic review.

Material and Methods:

A systematic literature search using Epistemonikos, Google Scholar, PubMed, and Scopus was done until February 2023. The appropriate observational and experimental research comparing the effects of ERAC protocols with conventional care on postoperative adverse events, operation-related characteristics, time to first (oral intake, mobilization, bowel movement, and urinary catheter removal), and opioid use. Meta-analyses were conducted using the RevMan 5.4.1. and Comprehensive Meta-Analysis version 3.3 software.

Results:

In total, 23 studies were included in this systematic review. ERAC implementation was found to be associated with improvement in terms of shorter postoperative hospital stays and faster time to first liquid intake, first solid diet, urinary catheter removal, and mobilization. Furthermore, the rate of opioid-free treatment, total in-hospital morphine milligram equivalent (MME), daily in-hospital MME, and total prescribed opioid pills at discharge (all parameters, P < 0.01) were significantly better in the ERAC group than in the conventional care group. However, no significant difference was observed regarding postoperative adverse events, blood loss, operation duration, and total prescribed MME at discharge parameters between the two observed groups.

Conclusion:

ERAC implementation is associated with better healthcare delivery, as determined by shorter time to first, lower opioid consumption, and shorter postoperative length of stay compared with conventional care. However, it is not associated with a lower dosage of opioid prescription at discharge.
Efficacy of clear aligner therapy over conventional fixed appliances in controlling orthodontic movement: A systematic review
Authors: AlMogbel AbdulMajeed , Alshawy Ebrahim S. , Alhusainy Abdulmageed
Published: May 2024

OBJECTIVE:

The purpose of the current systematic review was to answer the clinical research question “Is Clear Aligner Therapy (CAT) effective in controlling the orthodontic movement?” by bringing together the most up-to-date information about the available evidence for CAT.

METHODOLOGY:

On January 1, 2023, a search was conducted in PubMed, ERIC, Embase, and CINHAL for any research papers published in the previous 10 years that provided an overview of the PICO questions. Both the titles and abstracts of the selected studies were evaluated independently by two different authors, and if there was any disagreement between the two review authors, a third reviewer was brought in to settle it.

RESULTS:

Among included studies, three were retrospective non-randomized and two studies were prospective randomized clinical trials. Various authors reported better outcome for fixed orthodontic appliances than for clear aligner treatment (CAT) in relation to mandibular incisor proclination. The mean objective grading system score was better for braces (17) than for CAT (12) with no clinically significant difference, while staging had a significant impact on treatment efficacy.

CONCLUSION:

The results of this study suggest that clear aligners may be an effective alternative to traditional braces, but more research is needed to confirm these findings and determine the optimal size of future prospective studies evaluating this treatment.
Comparative evaluation of effectiveness of three versus four mini-implants for simultaneous intrusion and retraction of maxillary anterior teeth: A 3D FEM study
Authors: Gupta Sajal , Khera Amit Kr. , Raghav Pradeep , Wadhawan Ashutosh , Wadhwa Pankaj , Sharma Nupur
Published: May 2024

OBJECTIVE:

To evaluate and compare the displacement pattern of maxillary anterior teeth in the sagittal and vertical planes and evaluate the stress distribution in pdl, bone, teeth of the maxillary anterior region, and around the mini-implants during simultaneous en-masse retraction and intrusion using two, three, and four mini-implants combinations.

METHODS:

A three-dimensional FEM model of maxillary teeth and periodontal ligament housed in the alveolar bone with extracted first premolarswasgenerated. The models were broadly divided into three groups according to the number of mini-implants. Mini-implants were placed bilaterally between the second premolar and molar in group I, and along with bilateral implants, an additional mid-implant was placed between the central incisors as in group II, whereas in group III, anterior mini-implants were placed in between lateral incisors and canine bilaterally.

RESULTS:

The two mini-implant model showed the maximum amount of retraction in the sagittal plane followed by three and four mini-implant models. In the vertical plane, all six anterior teeth showed intrusion only in the four mini-implant model. The stress in cortical bone, cancellous bone, PDL, around the mini-implants, and in lateral incisor was maximum in the three mini-implant model, followed by four mini-implants with the least stress in the two mini-implant model.

CONCLUSION:

The four mini-implant model is better than the three and two mini-implants model as there is a more even distribution of force in the four mini-implants model as compared to the three mini-implants model.
Restriction theorems for semistable sheaves
Authors: Pavel Mihai
Published: May 2024

In this paper we prove restriction theorems for torsion-free sheaves that are (semi)stable with respect to the truncated Hilbert polynomial over a smooth projective variety. Consequently, this settles a conjecture of Langer in the affirmative. Our results apply in particular to Gieseker-semistable sheaves and generalize the well-known restriction theorems of Mehta and Ramanathan. As an application we construct a moduli space of sheaves in higher dimensions.

G

. The construction is inspired by recent work of Karoubi and Weibel (2016), initially applied to topological spaces. We introduce a similar notion in combinatorial form in order to apply it to finitely presentable groups. Some properties of this complexity as well as a few examples of calculation/estimation for certain classes of finitely presentable groups are considered. Finally, we give a few applications of complexity to some geometric problems, namely to the systolic area and the volume entropy of groups.

Adolf de Herz și comedia de bulevard
Authors: Vasiniuc Tiberius
Published: May 2024

Considered one of the first authors of boulevard comedies in Romania, A. de Herz is almost absent from the pages of the of Romanian literature history. Nevertheless, the theater history gives him an important place, through his light comedies, with great appeal to the interwar audience. If the plays of historical inspiration remained without an echo when they were published, the comedies "Păianjenul" (“The Spider”), "Bunicul" (“The Grandfather”), "Sorana", "Mărgeluş" (“Tiny Bead”) and "Încurcă-lume" (“The Fumbler”) have been performed on numerous stages in the country, including the National Theater of Bucharest and the National Theater of Craiova. An important chapter in his theatrical activity is the collaboration with C. Tănase and the “Cărăbuș” Theatre. In several plays he performed secondary roles, very well received by the public. With extensive journalistic activity at "Dimineața", "Adevărul", "Adevărul literar și artistic", "Rampa", "Convorbiri critice" etc., Herz was for a good period of time one of the well-known theatre columnists of that epoch. Often, in order to create a relaxed atmosphere for the audience, the author chose to explore current topics, but without great pretensions, full of mundane conversations and expressions with claims of aphorisms. Director of the National Theater of Craiova (1930-1935), A. de Herz prematurely ended his existence, leaving only a few pale traces of his entire creation over time.

Authors: Godwin Mtae Harrieth
Published: May 2024

This study investigated the Mbozi Meteorite as a Niche for Community Development in Songwe Region, Tanzania. The study applied the cross-sectional research design where a mixed research method was applied. The population of the study was 160,529 people from the seven wards in the district. From this population, the sample size per Ward ranged from 15-30 participants making a total sample size of 135 respondents. Community members were interviewed using a semi-structured questionnaire. Focus group discussions (FGDs) comprising men, women and youths were also conducted. Quantitative data was processed using the SPSS version 21. Qualitative data was analysed thematically. Almost all of the surveyed population are aware of the Mbozi meteorite. Most of the respondents became aware of it between 2000 and 2010 with a significant proportion learning about it in school. There is a need to introduce education outreach programs that can play a crucial role in raising awareness about the significance of the Mbozi Meteorite. Furthermore, there is a need to collaborate with local tourism and cultural organizations to increase awareness and attract visitors by promoting the Mbozi meteorite as a unique tourist attraction by highlighting its historical and scientific significance. Finally, there is a need for diversifying advertising channels by utilizing traditional media platforms like Television, radio, social media, online forums and websites as well as print media, to reach a wider audience nationally and internationally.

This study examined public perception on frequency and adequacy of media information on the Sustainable Development Goals (SDGs) in Ghana, using the descriptive survey design. The study population was made up of Ghanaians who were 18 years or above. Convenient sampling method was used to select 431 Ghanaians. Data was gathered through questionnaire administration. Analytical techniques for the study included frequencies, percentages, means and standard deviations. The study found that social media was the most dominant source of information among Ghanaians, followed by television, with newspapers identified as the least dominant source of information. Generally, Ghanaians perceived the level of frequency of media information on SDG 1 (Ending poverty) as high. Again, the level of frequency of media information on SDG 2 (Ending hunger and achieving food security), SDG 3 (Healthy life) and SDG 5 (Gender equality) was moderate. However, the level of adequacy of media information on SDG 9 (Industry, and infrastructure), SDG 10 [Reduced inequality] and Goal 11 [Sustainable cities and communities] was very low. As a recommendation, Ghanaian media should pay increased attention to the use of the new media especially social media when covering and reporting issues related to the SDGs. Furthermore, media organizations in Ghana should consider the use of radio and television as critical sources of frequent and adequate information on the SDGs. Finally, media organizations should re-examine their daily and weekly programs to ensure that equal attention is given to all the 17 SDGs.
Rodolfo Kusch: de una psicogeografía de la barbarie a una epistemología geocultural de lo popular
Authors: Monk Pablo
Published: May 2024

En La seducción de la barbarie Kusch, propone un viaje a la psicología social americana que explora la escisión entre el deseo de ser (individual y/o colectivo) y aquello que (consciente e inconscientemente) se es. Este dualismo, conformado por la barbarie autóctona y la civilización arraigada en la mentalidad ciudadana, configura una psicogeografía continental en la que lo auténtico y lo ficticio tensionan histórica, epistemológica y metafísicamente. Las reflexiones que el autor desarrolla posteriormente en Geocultura del hombre americano en torno de lo popular y de la cultura como geocultura (que comporta una ubicación, que es propia de una comunidad y que presenta características peculiares que la diferencian), propician una deriva de la antinomia “civilización y barbarie” a la búsqueda de una expresión cultural auténtica del modo de vivir americano (estar-siendo). ¿En qué sentido se puede pensar o expresar esa autenticidad americana ligada a una manera particular de vivir el suelo? ¿Qué tipo de inautenticidad pondría de manifiesto? Más aún, ¿no podría contener esa manera de vivir y ese suelo los lineamientos y las preconfiguraciones hacia otra epistemología? ¿Hacia otra manera de saber lo americano?

Los gabinetes escolares de Historia Natural eran considerados claves para la enseñanza de las ciencias naturales, de acuerdo a diversas propuestas educativas implementadas durante los siglos XIX y XX en Iberoamérica. Hoy en día, estos antiguos gabinetes se han transformado en espacios histórico-patrimoniales que nos permiten indagar sobre las relaciones entre la ciencia y la educación y las aproximaciones a esta naturaleza reinterpretada desde un enfoque científico-pedagógico. En este estudio, enfatizamos en los gabinetes de Historia Natural y sus transformaciones, de espacios científicos a espacios patrimoniales, destacando la importancia que tuvieron las colecciones de taxidermia como parte de los gabinetes de Historia Natural existentes tanto en Chile como en el contexto iberoamericano. A su vez, identificamos cuáles han sido algunos de los esfuerzos de preservación que se han llevado a cabo, reflexionando sobre sus proyecciones como patrimonio.

Învățarea – rețetă într-o realitate educațională construită social
Authors: CALLO Tatiana
Published: May 2024

The article addresses the issue of learning, the necessity of which has arisen due to the emphasis on the social character of learning in general in the new community conditions, among which is included „the weakening of the desire to think, simply, elementary”. When individual learning is subordinated to the social, and the human dimension is conditioned, not least, by the quality of learning, this factor becomes decisive in the complexity of the learning process as such. It is about recipe-learning, which is a learning related to the student’s immediate context, a non-problematic but useful practical learning, giving the student the chance to orient himself in the social universe of today’s reality. The idea that supports the learning-recipe is the usefulness of what is learned in everyday, social life in order to satisfy a precise, immediate goal.
