Does the water resource ‘fee to tax’ policy alleviate water poverty? Evidence from a quasi-natural experiment
Authors: Mu Lan , Mou Muge , Tang Heyan
Published: November 2022

Levying a water resources tax policy which is called ‘fee to tax’ is a regulation formulated by China to restrain and alleviate water poverty. To test the effect of the water resources ‘fee to tax’, this research employs a multistage dynamic difference-in-differences (DID) model to explore whether the implementation of the policy can help alleviate water poverty based on panel data from 2009 to 2019. The results indicate the water poverty in western China is significantly more serious than in other regions and the implementation of the water resources tax policy significantly alleviates water poverty (the sign of the policy is positive and significant at the 1% level) in China. Additionally, the mechanism effects suggest that the policy can effectively restrain water poverty by reducing groundwater exploitation and optimizing the water utilization structure. In terms of spatial heterogeneity, the effect of the water resources tax policy on alleviating water poverty is stronger in central and eastern regions than in western regions. The conclusions of this study may, to some degree, serve as a basis to scientifically guide the implementation of China's water resources ‘fee to tax’ policy and, thus, effectively improve the level of water resources management.

The wide antibiotics use in different areas of medicine has significantly increased the incidence of pseudomembranous colitis caused by Clostridium difficile. Strong necessity of antibacterial therapy in hematological patients is the reason of a higher frequency of this complication after programmed chemotherapy and hematopoietic stem cell transplantation. The atypical course of clostridial colitis makes it difficult to diagnose, leads to delay of treatment and fatal complications. We presented the case of clostridial colitis with atypical clinical manifestations in the 8-year-old child with Hodgkin’s lymphoma. Disease was complicated by colon perforation and fecal peritonitis, which required surgery and long-term rehabilitation. The analysis of publications devoted to clostridial colitis in patients with hematological malignancies was carried out and possible reasons of its atypical course was reviewed. The ways to improve the diagnosis, treatment and prevention of this serious complication are presented.

Authors: Burtsev E. A. , Bronin G. O.
Published: November 2022

Background. There are increasing data of targeted therapy efficacy of different types of Langerhans cell histiocytosis (LCH) with inhibitors of BRAF-specific serin-threonine kinase (BRAF-inhibitors) in cases with BRAF V600E mutation published last years. At the same time there are no published data of use of inhibitors of MAPK/ERK pathway (MEK-inhibitors) in pediatric patients with BRAF-negative forms of LCH.

Purpose of the study is to evaluate efficacy and safety of MEK-inhibitor (cobimetinib) in eight pediatric BRAF V600E-negative refractory LCH patients.

Materials and methods. The study included 8 children with various forms of LCH. All patients received therapy according to the LCH-IV protocol and were diagnosed with progression of LCH during or after termination of the treatment. The response to the therapy was assessed in accordance with the international scale Response Evaluation Criteria in Solid Tumors (RECIST v.1.1). The assessment of the toxicity was performed in accordance with the international scale of Common Terminology Criteria for Adverse Events (CTCAE v.5.0).

Results. Complete response was not achieved in any patient. Partial response was established in 5 cases. One patient was diagnosed with disease progression in three months after termination of the therapy. The incidence of adverse events was high.

Conclusion. Cobimetinib therapy is effective in BRAF V600E-negative refractory pediatric LCH patients. The response to the treatment can be delayed. All cases of the toxicity were dose depended and successfully resolved after dose correction. Further research is needed to define duration of treatment and optimal dosage.

O SARS-CoV-2 é um vírus que causou grande impacto no mundo. Possui alta transmissibilidade, infectando muitas pessoas em pouco tempo e causando a covid-19, doença que pode ou não ser assintomática. Os sintomas mais comuns são: febre, tosse, dor de cabeça, dor no corpo (muscular), náusea, fadiga, falta de ar ou dificuldade para respirar, diarreia, cansaço, perda do olfato (anosmia) e do paladar (disgeusia). A disgeusia ocorre por meio da atração da proteína spike (S), que o vírus possui, pelas enzimas conversoras de angiotensina-2 (ACE2), presentes na mucosa oral, língua e regiões envolvendo o trato respiratório. Essa invasão causa uma inflamação nas células, fazendo com que haja perda, ou não, de suas funções, como a sensação do paladar. Objetivo: Avaliar os sintomas apresentados por pessoas que testaram positivo para SARS-CoV2, com enfoque especial na ocorrência de disgeusia e suas manifestações clínicas. Material e métodos: Foi realizado um estudo, por meio de um questionário produzido pelo Google Forms, com 17 perguntas, para avaliar os sintomas apresentados por pessoas infectadas pelo SARS-CoV-2. Obtiveram-se 261 respostas. Resultados: Mulheres e pessoas mais jovens são mais propensas a apresentarem manifestações causadas pela variação delta do vírus SARS-CoV-2, incluindo a perda no paladar. Os sintomas mais relatados foram cansaço, dor no corpo e dor de cabeça. A disgeusia foi relatada por 172 (65,90%) pacientes. As disfunções olfatórias e gustativas foram encontradas simultaneamente em 138 (52,87%) infectados. Conclusão: A disgeusia é um sintoma comum relacionado à infecção por SARS-CoV-2 e causa um grande impacto na vida das pessoas, sendo, portanto, parte das responsabilidades do cirurgião-dentista identificá-la e orientar seus pacientes. Além disso, foi possível notar que, apesar de anosmia e disgeusia se manifestarem simultaneamente em diversos casos, uma disfunção não depende da outra.

Published: November 2022

Introdução: Os implantes osseointegrados foram introduzidos no início dos anos 1980, possibilitando outras alternativas de tratamento protético reabilitador. Muitos problemas oriundos das próteses convencionais foram solucionados por intermédio da osseointegração, porém complicações estéticas, fonéticas, funcionais, biológicas e mecânicas podem acontecer caso um adequado plano de tratamento não seja executado previamente à cirurgia do paciente. Objetivo:O objetivo do presente trabalho foi relatar a remoção de implantes dentários mal posicionados, em virtude da falta de planejamento prévio contraindicando a reabilitação protética. Relato de caso:Paciente do sexo feminino, 36 anos de idade, foi submetida à cirurgia de remoção de dois implantes, por causa de posicionamento inadequado e falha na osseointegração. Conclusão: O uso de todos os métodos diagnósticos disponíveis no planejamento, juntamente com a abordagem clínica adequada, é imprescindível para o sucesso do tratamento com implantes, evitando ao máximo a necessidade de remoção e substituição.

Authors: Edson Alves CAMPOS  , José Roberto Cury SAAD  , Sizenando Toledo PORTO NETO  , Lucas Arrais CAMPOS  , Marcelo Ferrarezi ANDRADE
Published: November 2022

Introdução: Sistemas adesivos convencionais são caracterizados pelo condicionamento ácido da estrutura dental previamente à aplicação dos monômeros. Esses materiais podem ser classificados em 3 passos (quando primer e adesivo se encontram em frascos separados) ou 2 passos (em que a função de primer e adesivo é desempenhada por um único material). Objetivo: Verificar a influência do momento da inserção do material restaurador (inserção imediata ou tardia) sobre os valores de resistência de união de adesivos convencionais de 2 e 3 passos por meio do teste de microtração. Material e métodos: Foram utilizados dentes incisivos bovinos que tiveram sua superfície vestibular desgastada até se obter uma superfície plana em dentina. Empregaram-se sistemas adesivos convencionais de 3 passos (Scotchbond Multi-Uso – SMP; Optibond FL – OFL; Bond-It – BIT) e de 2 passos (Single-Bond – SB; Optibond Solo Plus – OSP; Bond-1 – B1), e resina composta (Z-350) foi aderida a esse substrato em dois diferentes momentos: imediata e tardiamente (após 24 horas). Todos os procedimentos foram realizados com simulação da pressão pulpar fisiológica. Os resultados foram submetidos à análise estatística Anova e ao teste de Tukey (p < 0,05). Resultados: Para inserção imediata da resina composta, todos os adesivos apresentaram comportamentos semelhantes. Os sistemas adesivos de 3 passos não evidenciaram redução da resistência de união quando a resina composta foi inserida tardiamente. Já os sistemas adesivos de 2 passos tiveram sensível redução dos valores de resistência de união. A redução ficou em torno de 30,24% para SB, 27,19% para OSP e 28,21% para B1. Conclusão: Cuidado especial deve ser tomado durante o uso de sistemas adesivos convencionais de 2 passos. É aconselhável que a resina composta seja inserida e polimerizada imediatamente após a conclusão do procedimento adesivo.

Conclusão: Concluiu-se que o cloranfenicol não tem potencial teratogênico para induzir o aparecimento de fenda palatina em ratos.
Internal root resorption in the maxillary central incisor
Authors: Josué MARTOS  , Luiz Fernando Machado SILVEIRA  , Jaqueline de Moraes SOUZA  , Mozara Mignoni VIEIRA  , Carina Folgearini SILVEIRA
Published: November 2022

Introduction: Internal root resorption is a chronic inflammatory process initiated within the pulp space with the loss of dentin. The clastic cells present in the pulp tissue trigger a progressive resorption phenomenon. Case report and conclusion: This paper reports a clinical case of an internal root resorption in the permanent central incisor, at the middle third of the root canal. Because it is asymptomatic, internal root resorption needs an early diagnosis in order to institute the endodontic treatment before the process compromises the mineralized structures of the tooth.

Published: November 2022

Introdução: O sucesso do tratamento endodôntico está interligado à capacidade de selamento da restauração provisória, que busca impedir a infiltração bacteriana e a recontaminação do sistema de canais radiculares. Objetivo: O objetivo deste estudo foi avaliar o selamento de dois cimentos temporários à base de resina: Fill Magic Tempo e Bioplic. Material e métodos: Utilizaram-se 24 terceiros molares, dos quais 22 foram abertos até a câmara pulpar, resultando numa cavidade classe I, e divididos aleatoriamente: o grupo 1 foi restaurado com uso de Fill Magic Tempo (n = 10), e o grupo 2 foi restaurado utilizando Bioplic (n = 10). O grupo controle negativo não teve a câmara aberta (n = 2), e o grupo controle positivo foi aberto mas não foi restaurado (n = 2). Impermeabilizaram-se com esmalte a raiz e o ápice dos dentes, e todas as amostras foram imersas em azul de metileno a 2% e mantidas a 37°C por 72 h. Assim, seccionaram-se os dentes longitudinalmente, e a infiltração linear foi medida em mm, sendo posteriormente aplicada análise estatística com teste de Mann-Whitney com nível de significância de 5%. Resultados: A maior parte das amostras apresentou 1 mm de infiltração, e somente o grupo controle negativo obteve infiltração total. Não se encontrou diferença significante entre os materiais testados. Conclusão: Pode-se concluir que ambos os materiais à base de resina proporcionaram resultados satisfatórios no selamento periférico durante tratamento endodôntico.

Published: November 2022

Introdução e objetivo: Procurou-se avaliar cefalometricamente o espaço disponível para erupção dos segundos e terceiros molares superiores permanentes na região da tuberosidade maxilar após a distalização dos primeiros molares superiores. Material e métodos: A amostra foi constituída de 38 telerradiografias em norma lateral direita, de 19 pacientes brasileiros, leucodermas e melanodermas, com idade média de 9 anos e 5 meses, obtidas no início e após a distalização dos primeiros molares superiores permanentes. O espaço avaliado compreendeu da extremidade da tuberosidade maxilar à face distal do primeiro molar superior permanente. Para a análise estatística foi utilizado o teste t de Student, e na correlação entre espaço e angulação, o coeficiente de correlação de Pearson. Resultados e conclusão: O espaço correspondente entre a distal dos primeiros molares superiores permanentes e a extremidade da tuberosidade maxilar, na fase inicial e após a movimentação distal, não foi suficiente para a erupção dos segundos e terceiros molares superiores permanentes. As coroas, da fase inicial até o fim da movimentação distal, posicionaram-se mais para distal. Quanto à correlação das angulações das coroas dos segundos e terceiros molares superiores permanentes e o espaço para erupção, verificou-se que quanto maior a angulação distal das coroas menor o espaço oferecido para a erupção.

Published: November 2022

Introduction: The purpose of this study was to test different sealer removal protocols following root canal filling before adhesive seal of access cavities. Material and methods: Forty single root teeth were selected for the study, prepared to size 60 taper .02, and filled with AH plus and a single gutta-percha cone size 55 taper .02. Excess sealer was removed with: ethanol-moisturised foam pellet (group 1), pellet and additional etch-and-rinse procedure (group 2), pellet and additional preparation with a water-cooled diamond bur (group 3) or by etch-and-rinse following temporary filling for one week (group 4). Syntac and Tetric flow were used as a secondary protective seal. A dye penetration test (centrifugation 3min / 30G; 5% methylene blue) was carried out. Results were analyzed statistically using PASW 18.0 (Kolmogorov-Smirnov-test, Kruskal-Wallis-test, Mann-Whitney-test; p < 0.05). Results: Groups 2, 3 and 4 revealed less leakage than group 1 (p < 0.05; Mann-Whitney-tests) and displayed no coloration exceeding the adhesive seal. Teeth with immediate (group 2) or delayed (group 4) adhesive seal showed similar results. Conclusion: Acid etching or bur preparation may be recommended before adhesively sealing the access cavity in single-rooted teeth. There is no need to wait until the sealer has set.

Authors: Kokoev M. N. , Fedorov V. T.
Published: November 2022

Objective. International practices demonstrate advantages of expanded clay in road construction in difficult climatic and geotechnical conditions. The clay is present in abundance in Siberia and in the Far North which is suitable for the production of expanded clay gravel. At the same time there is a strong deficit of the road construction materials in these regions. The aim of the study is to develop a new approach for providing claydite for the construction of northern roads.

Method. The modernization of the equipment means that each unit included in the complex can be transported on existing trucks, and then mounted in a line for the production of expanded clay in the field.

Result. A mobile complex for the production of expanded clay gravel, serial and modernized equipment for the production of expanded clay has been developed.

Conclusion. Large units - drying drums and rotary kilns for drying and firing pellets should be divided into prefabricated sections, for example, with a diameter of 2 m and a length of 5-7 m. For the electric drive of the units, a diesel generator of sufficient power must be included in the equipment set. The productivity of one complex is from 15 thousand cubic meters of expanded clay per year and above.

Background

Ultrasound for gestational age (GA) assessment is not routinely available in resource-constrained settings, particularly in rural and remote locations. The TraCer device combines a handheld wireless ultrasound probe and a tablet with artificial intelligence (AI)-enabled software that obtains GA from videos of the fetal head by automated measurements of the fetal transcerebellar diameter and head circumference.

Objective

The aim of this study was to assess the perceptions of pregnant women, their families, and health care workers regarding the feasibility and acceptability of the TraCer device in an appropriate setting.

Methods

A descriptive study using qualitative methods was conducted in two public health facilities in Kilifi county in coastal Kenya prior to introduction of the new technology. Study participants were shown a video role-play of the use of TraCer at a typical antenatal clinic visit. Data were collected through 6 focus group discussions (N=52) and 18 in-depth interviews.

Results

Overall, TraCer was found to be highly acceptable to women, their families, and health care workers, and its implementation at health care facilities was considered to be feasible. Its introduction was predicted to reduce anxiety regarding fetal well-being, increase antenatal care attendance, increase confidence by women in their care providers, as well as save time and cost by reducing unnecessary referrals. TraCer was felt to increase the self-image of health care workers and reduce time spent providing antenatal care. Some participants expressed hesitancy toward the new technology, indicating the need to test its performance over time before full acceptance by some users. The preferred cadre of health care professionals to use the device were antenatal clinic nurses. Important implementation considerations included adequate staff training and the need to ensure sustainability and consistency of the service. Misconceptions were common, with a tendency to overestimate the diagnostic capability, and expectations that it would provide complete reassurance of fetal and maternal well-being and not primarily the GA.

Conclusions

This study shows a positive attitude toward TraCer and highlights the potential role of this innovation that uses AI-enabled automation to assess GA. Clarity of messaging about the tool and its role in pregnancy is essential to address misconceptions and prevent misuse. Further research on clinical validation and related usability and safety evaluations are recommended.

Cats and dogs have a very close relationship with humans. Currently, the overpopulation of these species in various countries worldwide has been identified as a severe public health problem. To establish effective programs for population control, it is necessary to estimate the number of cats and dogs. To our knowledge, there are no studies that assess the number of canine and feline population by state in Mexico. Therefore, this study aimed to estimate the canine and feline population living at homes using official information reported by the National Institute of Statistics, Geography and Informatics [Instituto Nacional de Estadística Geografía e Informática] through a constant-share model, a ratio extrapolation method. The estimated dog population living at homes was 42 625 010 dogs and 7 346 925 cats (at least 5.8 times less than the number of dogs). By 2022, the Mexico's estimated human:dog ratio was 2.4:1, and the human:cat ratio 17.6:1. The Estado de México had more than six million dogs and 962 177 cats. Colima had the smallest estimated dog population (245 489), and Baja California Sur the smallest estimated cat population (slightly over 30 000). Health authorities and veterinary practitioners should promote responsible ownership to increase veterinary care and control the birth of dogs and cats.

Escherichia coli is one of the most important bacteria associated with the consumption of meat products causing human disease, with bovines as the main reservoir for this organism. Microbiological quality of raw meat sampled at slaughterhouses was evaluated by measuring the presence of Escherichia coli serogroups that produce the Shiga toxin (referred to as STEC), including both O157:H7 and non-O157 strains can cause Hemolytic Uremic Syndrome (HUS). The purpose of this study was to detect STEC O157 and non-O157 in meat products from Federal Inspection Type (FIT, n=52) and non-FIT (n=88) slaughterhouses, as well as butcheries (n=50), in southern Sonora, Mexico. To achieve this aim, selective media were employed to obtain putative O157:H7 colonies (TS-SMAC agar and Rainbow® agar O157), followed by multiplex PCR for the stx1, stx2, eaeA, and rfB genes, using the O157:H7 serotype as a control. No STEC O157 was found in beef products, but some non-O157 isolates were found containing the stx2 pathogenicity gene (1.40%, 3/224) and/or the fliCH4 flagellar antigen (1.78%, 4/224). This work also confirmed the susceptibility of strains with the stx2 and/or fliCH4 genes to several antibiotics and multi-resistance of all or some of these strains to trimethoprim/sulfamethoxazole, tetracycline, clarithromycin, penicillin G, oxacillin, ampicillin and cefazolin. This study comprises the first report of STEC non-O157 in Sonora and will be useful to establish their association with foodborne outbreaks originating from beef and pork consumption in the future.

La enseñanza de la historia en la escuela configura narraciones sobre nosotros en cuanto colectividad. Se acostumbra pensar estas narraciones dentro de una idea estable de lo que entendemos por ser mexicano o chileno, pero en las aulas y en los distintos espacios públicos tales relatos se tornan fragmentarios, antagónicos, coyunturales e incluso contradictorios entre sí. En este movimiento la historia —en la escuela y en los espacios públicos— ha incorporado a sus narrativas temas casi del todo ausentes hasta ahora, como los de género, grupos marginados y hechos recientes de alta significación que son de primera importancia para dar vida a una nación y un futuro más justos y equitativos. Enseñanza y usos públicos de la historia… reúne a especialistas de dos naciones diversas, pero con preocupaciones afines respecto a su memoria colectiva: Chile y México, en una gran variedad de enfoques y estrategias metodológicas que dibuja un amplio panorama de lo que hoy significa la historia en América Latina. Este libro es una puesta al día ineludible en la investigación comparada sobre enseñanza de la historia latinoamericana.
Green for Green: Approach to Sustainable use of Stubble
Authors: Chatterjee Saurav
Published: November 2022

Abstract: The contemporary zeitgeist of the national capital is rendered in haze and smog due to extensive stubble burning. The paper talks of the various steps the government has already taken and tries to identify the lacuna behind its unjust boom. It also looks at the effective use of various agro wastes and turning them into a 21st-century industry product, for biogas generation or construction material, which can foster a pyramidal development through economic, environmental, and social sustainability. It also identifies the indispensable role of the government not just in creating awareness and structuring better policies but rather in providing opportunities by agglomerating the demand and supply chain to stimulate the waste into revenue generation.
Optimization Improvement Using Pi Controller to Reach CCCV Method in Lead Acid Battery Load

Solar energy can produce electrical energy with the help of photovoltaics so as to produce sufficient or even excessive supply to the electrical load. Therefore, it is necessary to store electrical energy (battery) from the excess unused energy. However, in the process of charging the battery, it takes a long time to fully charge the battery capacity and damage often occurs due to excessive voltage used. This can reduce battery life. The characteristics of the battery need to be considered so that the charging process can be carried out in accordance with the required provisions. The existence of the CCCV method can speed up the battery charging process with a constant current of 20% of the nominal current of the lead acid battery. To avoid overvoltage, the constant voltage method can anticipate the occurrence of damage. Utilization CUK Converter as charging can reduce output voltage ripple. The PI control on the CUK Converter produces a constant voltage of 13.8 Volts and a constant current of 1.44 Ampere. The average error generated by this system is 0.14%.

Published: November 2022

Image captioning is one of the biggest challenges in the fields of computer vision and natural language processing. Many other studies have raised the topic of image captioning. However, the evaluation results from other studies are still low. Thus, this study focuses on improving the evaluation results from previous studies. In this study, we used the Flickr8k dataset and the VGG16 Convolutional Neural Networks (CNN) model as an encoder to generate feature extraction from images. Recurrent Neural Network (RNN) uses the Bidirectional Long-Short Term Memory (BiLSTM) method as a decoder. The results of the image feature extraction process in the form of feature vectors are then forwarded to Bidirectional LSTM to produce descriptions that match the input image or visual content. The captions provide information on the object’s name, location, color, size, features of an object, and surroundings. A greedy Search algorithm with Argmax function and Beam-Search algorithm are used to calculate Bilingual Evaluation Understudy (BLEU) scores. The results of the evaluation of the best BLEU scores obtained from this study are the VGG16 model with Bidirectional LSTM using Beam Search with parameter K = 3 and the BLEU-1 score is 0.60593, so this score is superior to previous studies.
Safety Climate and Safety Behavior in A Hotel : Focusing on the Moderating Effect of Safety Leadership
Authors:   Korean Academy of Leadership, Chang Huseok , Hahn Juhee
Published: November 2022

The purpose of this study is to investigate the effect of the hotel safety climate on the safety behavior of hotel workers, the mediating role of safety motivation, and the moderating role of safety leadership. Five hotels in China were targeted, and to prevent common method bias, the questionnaire was conducted three times with a time lag, and a total of 512 valid data were obtained. To verify the hypothesis, analysis was performed through the SPSS Process Macro. The study results indicate that a safety climate positively affects the safety compliance and safety participation of hotel workers. In addition, safety motivation mediated the relationship between safety climate and safety behavior, and the moderating effect of safety leadership on safety compliance was also supported. However, there was no moderating effect of safety leadership on safety participation, which is inferred to be due to the characteristics of the hotel industry. As a result of this study, it was found that safety leadership, a topic that was rarely addressed in previous safety-related studies, moderates the relationship between safety motivation and safety behavior of hotel workers. In addition, in the hotel industry, safety-related areas are being expanded through self-determination theory to understand the safety behavior of hotel workers and customers. Based on these research results, it can be suggested that hotels should develop strategic plans to establish a positive safety climate and actively come up with measures to motivate hotel workers to take safety behavior. However, the lack of coherence in terms because existing safety-related studies were mainly dealt with in psychology and engineering fields, makes it clear that the establishment of terminology should be preceded in the future. In addition, the limitation of this study is that the analysis of safety-related variables was carried out without distinction at the group level or the individual level.
Science communication: a messy conundrum of practice, research and theory
Authors: Metcalfe Jennifer
Published: November 2022

Theoretical perspectives of science communication were initially driven by practice, which in turn have influenced practice and further science communication scholarship. The practice of science communication includes a variety of quite diverse roles. Likewise, the scholarship of science communication draws upon a mix of disciplines. I argue that the apparent messiness of science communication scholarship and practice is also its wealth. If blame can be avoided in developing and applying science communication models, and if the coexistence of all science communication models can be embraced then both the scholarship and practice of science communication is likely to be more effective.
Research in science communication in Latin America: mind the gap
Authors: Massarani Luisa , de Oliveira Thaiane
Published: November 2022

In this commentary, we discuss the challenges associated with carrying out research in science communication in Latin America. We start with the ‘‘invisibility’’ of Latin American studies in the three most prominent international journals in the field (although there has been a growing number of studies in the region). Then, we look to the recent popularisation of science through social media, the political issues facing the region and the massive spread of disinformation and fake news, which has been widely accentuated by the pandemic. We argue that there is an urgent need but also opportunities for innovation and collaborative research in science communication. Finally, we call attention to how the present situation might lead to bigger gaps among researchers from the developing world, including Latin America, and the so-called developed world.
Citizen science communication and engagement: a growing concern for researchers and practitioners
Authors: Hecker Susanne
Published: November 2022

Anniversaries provide great opportunities to celebrate achievements, to look into the future, and to do some self-reflection. I have the honour of doing so in a specific field of science communication that I’m familiar with: the field of citizen science communication, especially with a European focus. I hope this commentary prompts others who are experts in their regions of the world to also reflect on the past and the future for this growing field.
Order preserving maps on quantum measurements
Authors: Heinosaari Teiko , Jivulescu Maria Anastasia , Nechita Ion
Published: November 2022

We study the partially ordered set of equivalence classes of quantum measurements endowed with the post-processing partial order. The post-processing order is fundamental as it enables to compare measurements by their intrinsic noise and it gives grounds to define the important concept of quantum incompatibility. Our approach is based on mapping this set into a simpler partially ordered set using an order preserving map and investigating the resulting image. The aim is to ignore unnecessary details while keeping the essential structure, thereby simplifying e.g. detection of incompatibility. One possible choice is the map based on Fisher information introduced by Huangjun Zhu, known to be an order morphism taking values in the cone of positive semidefinite matrices. We explore the properties of that construction and improve Zhu's incompatibility criterion by adding a constraint depending on the number of measurement outcomes. We generalize this type of construction to other ordered vector spaces and we show that this map is optimal among all quadratic maps.
La reparación de los perjuicios compensatorios y moratorios como tipología de perjuicios derivados de la responsabilidad contractual en el derecho privado
Authors: Hernández Tous Alfonso
Published: November 2022

Este artículo plantea de manera sistemática y coherente los principales aspectos que se deben tener en cuenta cuando se hace referencia a una precisa categoría de resarcimiento de daños, como lo es la reparación por equivalente, vale decir, la indemnización de perjuicios compensatorios y moratorios; categoría que es omnicomprensiva de todos los posibles perjuicios patrimoniales que se pueden reclamar dentro de los procesos por incumplimientos contractuales. En esa línea de pensamiento, se establece la relación lógica existente entre estas categorías indemnizatorias con los tipos de incumplimientos que se pueden dar en materia contractual, y su conexión con instituciones propias del derecho de daños como el daño emergente y el lucro cesante.
Interpretativismo, “doctrina Chavela Vargas” y populismo penal
Authors: Grbavac Hernán Darío
Published: November 2022

El populismo penal se ha transformado, desde la década de 1980, en el paradigma dominante en materia de seguridad pública y control del delito en Occidente. Generalmente, es identificado con discursos reaccionarios y de “mano dura” contra el crimen. Este trabajo, sin embargo, justificará que el populismo penal no solo es compatible con el populismo penal de derecha, sino también con el populismo penal de izquierda o progresista. Se recordará el análisis teórico sobre el populismo de Laclau y, luego, las notas distintivas del populismo penal y el contexto político y social de su emergencia y consolidación. Asimismo, se sostendrá que ciertas características del populismo penal facilitan la vigencia de una práctica acerca de la aplicación del derecho penal: el “interpretativismo” y —su cara más visible— la “doctrina Chavela Vargas de la interpretación”. En esa línea, se recordarán tres sentencias judiciales de altos tribunales argentinos que permiten dar cuenta del fenómeno del populismo penal en sede judicial, vale decir, del uso por parte de los jueces de la “doctrina Chavela Vargas” y los deletéreos efectos que ello trae aparejado para la autoridad del derecho.

Authors: FERNÁNDEZ MATEOS Rubén
Published: November 2022

Colgadas de los muros del coro de la catedral de Palencia se conservan seis tablas de pequeño formato que, por el estilo que presentan, pueden atribuirse al pintor Juan de Villoldo, discípulo de Alonso Berruguete. Se hace una breve biografía de Villoldo, se analiza su estilo y se dan a conocer las pinturas con los cuatro Evangelistas, San Andrés y Santa Ana, la Virgen y el Niño, comparando sus formas con las de otras obras documentadas y atribuidas al maestro. Además, se propone el posible origen de las mismas.
