Descolonialidade e questão ambiental crítica:
Authors: Costa César Augusto
Published: February 2022

A intenção deste texto é indicar algumas contribuições do pensamento descolonial através da interlocuções teórico-políticas de Paulo Freire para a questão ambiental crítica na América Latina (AL). Freire expressa de forma política em seu pensamento pedagógico uma concepção de filosofia educacional orientada pela finalidade da libertação. Sua pedagogia crítica descolonial têm no horizonte, a libertação daqueles sujeitos que habitam as periferias negadas pelo sistema-mundo moderno-colonial, a possibilidade do “vir a ser mais”. Desse modo, cabe situarmos a relevância política e pedagógica evidenciada de Paulo Freire em diálogo com o campo ambiental, uma vez que ele não se declarou um ambientalista, nem nunca produziu sobre o campo ambiental. Encontramos nesta interlocução, o caráter libertário na ação contrária e dialética do processo colonial, pois os espaços abertos entre a cultura dominante e a resistência da dominação são relevantes para essa discussão. O artigo está sistematizado em três momentos: no primeiro, introduziremos a discussão sobre a descolonialidade e a interlocução em Paulo Freire na AL. No segundo momento, refletiremos a relação entre descolonialidadade e a questão ambiental à luz das aproximações em Freire. Nas considerações finais, explicitaremos as contribuições de uma perspectiva descolonial do educador brasileiro para o debate ambiental crítico.
Movimentos sociais, alternativas ao desenvolvimento e construção educativa popular na América Latina
Authors: Coelho Larissa Thomaz , Santos Leilane Nascimento dos Reis , Bambirra Liara
Published: February 2022

O presente trabalho tem como objetivo entender as lutas sociais na América Latina e Caribe que resistem ao modelo de desenvolvimento hegemônico, em uma percepção de suas trajetórias como agentes fundamentais na construção pedagógica popular. São os movimentos sociais e comunidades de atingidos que formulam as alternativas a esse modelo, que dita de forma desigual e dependente a formação política e social desses países. O artigo nasce com a proposta de relacionar os processos e práticas insurgentes para resistir, (re)existir e (re)viver pedagogias, ligados ao que Paulo Freire (2003) chamou de "motivos de esperança no desespero". A partir do trabalho construído coletivamente na Cartilha Pacha: defendendo a terra, publicada em 2018 pelo Grupo de Relações Internacionais e Sul Global da Universidade Federal do Estado do Rio de Janeiro (GRISUL-UNIRIO)[1], o artigo articula particularmente os aprendizados tecidos na resistência de mulheres atingidas pelo Extrativismo com a educação popular.
Educación Popular de Jóvenes y Adultos y docencia:
Authors: Urban Samuel Penteado , Paiva Santiago Juliana
Published: February 2022

El presente texto busca realizar una reflexión teórica respecto a la docencia en la Educación de Jóvenes y Adultos, en la perspectiva de la Educación Popular. Es importante señalar que esa reflexión no sólo deriva de lecturas, sino también de experiencias educativas de los autores. En ese sentido, para que fuera posible presentar las contribuciones de la pedagogía freireana, se ha realizado, inicialmente, una síntesis crítica acerca de la concepción autoritaria/antipopular de EJA. Em seguida, se presentó la concepción democrática y popular de Educación de Jóvenes y Adultos, y por fin, se discutió la docencia en EJA. Esto es, se hace menester plantearnos una educación que nos traiga la denuncia yel anuncio, en especial en la Educación de Jóvenes y Adultos. Eso porque, así como en el momento en que surgieron las primeras experiencias educacionales de Paulo Freire, el actual contexto sócio-histórico exige respuestas de los educadores comprometidos conlas clases populares y conla lucha contra todas las formas de opresión.
Paulo Freire, metodologias da educação popular e questões contemporâneas da relação ensino-aprendizagem
Authors: Gomes Rodrigo Lima Ribeiro
Published: February 2022

O presente trabalho tem o objetivo de apresentar a contribuição de Paulo Freire para se pensar os problemas contemporâneos da relação ensino-aprendizagem, considerando as demandas das mudanças sociais. Procuramos situar as origens da pedagogia freiriana nos debates acerca da educação popular e de adultos de finais da década de 1950 até 1964, que culminaram no seu “método Paulo Freire de Educação de Adultos”. Apresentamos alguns aspectos das ideias de Freire, desenvolvidos ao longo de sua trajetória, com o intuito de demonstrar como a forma de trabalhar de Freire, associada aos seus princípios político-pedagógicos, o levaram a abordar questões de grande atualidade. Para isso, recorremos brevemente a uma pequena amostra de artigos científicos escritos em inglês por pesquisadores de diversas partes do mundo, para demonstrar a relevância de Freire em nível internacional.
Diálogos com a Educação Ambiental desde el Sur a partir da “fotoescrevivência”
Authors: Maciel Salis Louise , Ricardo Dalma dos Santos , Patrocínio Janaína Pessanha , Martins Paolo de Castro , Pelacani Bárbara , Costa Rafael Nogueira
Published: February 2022

O artigo discute a experiência da disciplina Educação Ambiental oferecida para os cursos de Graduação da Universidade Federal do Rio de Janeiro. Questiona a ausência de saída de campo e de metodologias inovadoras no ensino de Ciências Biológicas. Dialoga com a “escrevivência” de Conceição Evaristo e propõe a “fotoescrevivência” como caminho para uma pedagogia decolonial. Encontra possibilidades para pensar a formação docente contextualizada com os territórios e com os conhecimentos ancestrais ao identificar “outras” pedagogias, como: resistência, conflito e da terra. Conclui que as experiências de trabalho de campo no âmbito da disciplina são pistas para uma formação mais plural, dialógica e criativa.

A escola deve ser um ambiente favorável à saúde. Desse modo, é fundamental investir na construção de entornos saudáveis. É possível ao ser humano agir de forma consciente sobre a sua realidade. A figura do educador deve ser considerada no desenvolvimento de ações em saúde na escola. Nisto consiste a Práxis humana resultante do processo de ação-reflexão particular sobre o mundo. O envolvimento com a realidade deve se apresentar como um objeto cognoscível por uma consciência crítica através do processo de conscientização. O educador, enquanto um agente influenciador, promove a saúde no contexto escolar, por isso, deverá, a partir de um processo de ação-reflexão da sua própria conduta, transformar o seu agir em ações que promovam saúde, e assim, construir um ambiente favorável para a aprendizagem. Este estudo tem como objetivo apresentar os dados de uma oficina que consiste em uma intervenção promotora de saúde para professores realizada em uma escola pública no distrito de Xerém, município de Duque de Caxias, Baixada Fluminense/RJ, por meio de uma oficina pedagógica embasada nos pressupostos teóricos de Paulo Freire. Após a validação da intervenção, a oficina ação-reflexão-ação foi realizada em sala remota, sendo constituída por quatro experimentos e contou com a participação de onze docentes. Durante a realização dos experimentos, os educadores compartilharam suas experiências e refletiram sobre suas ações no processo de ensino-aprendizagem.É preciso estimular a reflexão, o pensamento crítico sobre o impacto das ações individuais e coletivas no ambiente escolar ou educativo, a fim de promover saúde neste contexto.

Enhancing safe prescribing using a theory-informed feedback intervention
Authors: Coombes Ian , Donovan Peter , Mitchell Charles , Bullock Brooke , Noble Christy
Published: February 2022

Context Medical interns find prescribing challenging and lack readiness
when commencing work. Error rates remain high despite education,
supervision and pharmacists’ contributions. Feedback on prescribing may
improve performance. Yet, work-based prescribing feedback focuses on
rectifying errors. We aimed to improve prescribing using a
theory-informed feedback intervention. Methods In this mixed methods
study, we designed and implemented a feedback intervention, informed by
Feedback-Mark 2 Theory. Interns commencing internal medicine terms
engaged in the intervention. Prescribing performance was evaluated by
comparing the number of errors per order of at least 30 medication
orders per prescriber from weeks 1-3 (pre/baseline) and weeks 8-9
(post-intervention). Baseline interns’ audit findings were analysed and
discussed during individualised feedback sessions with either a clinical
pharmacologist (Site 1) or pharmacist educator (Site 2). Results
Prescribing by 88 interns, across two hospitals over five 10 week terms,
was analysed. Following the intervention, there was a significant
reduction in prescribing errors (p<0.001) from 1598 errors in
2750 initial orders (median [IQR] 0.48 [0.35-0.67] errors per
order) before and 1113 errors in 2694 orders (median [IQR] 0.30
[0.17-0.50] errors per order) after. There was no reduction in
initial error rate over the five terms. Conclusions Our theory-informed
feedback intervention contributed to a significant reduction in interns’
prescribing errors. This study opens up new strategies for improving
prescribing safety through feedback interventions. The results emphasise
that learner centred and improvement-focussed feedback with an agreed
plan could significantly improve prescribing safety an outcome which
supervision, education and pharmacist interventions had not delivered.

Published: February 2022

Land degradation and desertification (LDD) has become one of the most
urgent global environmental issues. The complexity of LDD make it
difficult to quantify, how to monitor quickly and accurately has become
the key to realize the sustainability for land resources. To achieve
this target, firstly, a comprehensive index—land degradation and
desertification status index (LDDSI) is built, which integrates the
information in fractional vegetation cover (FVC), net primary
productivity (NPP), albedo and modified temperature vegetation drought
index (MTVDI) based on the spatial principal component analysis (SPCA).
Then, identifies LDD from dynamics of land degradation and
desertification status (LDDS) in 2001-2018. Based on this, we analyze
the spatio-temporal process and driving mechanism of LDD in Northern
China. The result indicates that: (a) LDDSI has a better monitoring
performance, (b) LDD has been effectively alleviated, but the spatial
distribution of LDDS maintains a high clustering pattern, which is
difficult to be broken, (c) LDD in local regions is further expanded
(1.75%) affected by many factors, which deserves our attention, and (d)
the differences in climate, environmental backgrounds and human
activities play a key role in LDDS and LDD. In addition, we assess the
effectiveness of ecological projects implemented by the Chinese
government. The current understanding in the change pattern and
influencing mechanism for LDDS and LDD can provide a scientific basis
for formulating ecological policies based on local conditions.
Heat dissipation performance analysis and structural parameter optimization of oil-immersed transformer based on flow-thermal coupling finite element method
Authors: Yuan FaTing , Wang Yue , Tang Bo , Yang WenTao , Jiang Fa , Han YiLin , Han ShanShan , Ding Can
Published: February 2022

In this paper, a coupled flow-thermal field simulation model is established based on the parameters of the transformer. Then the distribution of the flow and thermal fields are obtained. The results show that oil backflow occurs to varying degrees at the top and bottom of the transformer. In addition, with the formation of backflow, the hot spot temperature of the transformer increases. Through the combination of orthogonal experiments and finite element method, the geometric structure of winding oil passage is selected as the optimization variable. The law between the winding structure and the maximum temperature is acquired by means of range and variance analysis, and the optimal parameters are obtained. The hot spot temperature is reduced by 34.27 K compared to the pre-optimization period, which is a guideline for the design of transformers.

Financial Statement Fraud: Evidence from Malaysian Public Listed Companies
Authors: Ismail Khan Norziaton , Muhammad Hapiz Arfa Aqila
Published: February 2022

Financial statement fraud is seen as a rampant problem around the world. Early detection is one of the ways to curb financial statement fraud, and it has motivated this study to be conducted.  The main objective of this study is to investigate the primary factors that influence the public listed companies in Malaysia to be involved in financial statement fraud. The sample used in this study comprised 40 financial statement fraud companies matched with another 40 non-financial statement fraud companies listed in Bursa Malaysia from 2003 to 2020. This study used the fraud triangle theory to form the research framework and develop the research hypotheses. Four hypotheses based on the elements of fraud, which are the financial target, external pressure, earnings management, and related-party transaction, have been developed and tested. Regression analysis was conducted to examine the relationship between the elements of fraud and financial statement fraud to test the hypotheses. The results indicated that financial targets, earnings management, and related-party transaction are accepted. However, external pressure was rejected. Interestingly, it was found that the fraud companies had poorer earnings quality one year before they committed the financial statement fraud. Overall, this study would assist the auditors as it identifies early warning signals or red flags. Information obtained from this study could be used by Bursa Malaysia to develop strong regulations and encourage the Malaysian public listed companies to enhance anti-fraud policies.

Evaluación de la periodontitis en cazadores-recolectores de Patagonia austral durante el Holoceno tardío (ca. 3500-200 años AP)
Authors: Pandiani Cynthia Daniela , Aranda Claudia , Flensborg Gustavo , Luna Leandro , Suby Jorge
Published: February 2022

La enfermedad periodontal es una infección que afecta los tejidos de sostén de las piezas dentales. A pesar de ser uno de los procesos infecciosos más frecuentes de la cavidad bucal, son pocos los trabajos que analizaron esta patología en restos humanos de cazadores-recolectores de Patagonia austral y, en consecuencia, su impacto en estas poblaciones no es bien comprendido. Por lo tanto, el objetivo de este trabajo es analizar si las poblaciones humanas de Patagonia austral presentaron altos niveles de periodontitis, considerada como la etapa tardía y destructiva de la enfermedad periodontal, a partir del estudio de una muestra de restos humanos del Holoceno tardío provenientes de esa región. Se analizaron 25 esqueletos de individuos adultos de ambos sexos, en los que se registró la presencia y el grado de periodontitis. Se calcularon las prevalencias en la muestra de acuerdo con el sexo, la edad, la subregión de procedencia y la cronología. Además, se exploró la posible relación de la periodontitis con otras patologías orales (caries, pérdida dental antemortem y lesiones periapicales), desgaste dental y con las reacciones periósticas proliferativas poscraneales registradas en la muestra, interpretadas como evidencia de procesos inflamatorios. Se observó una prevalencia de 36% (9/25) de individuos con periodontitis, con una mayor frecuencia entre los femeninos (3/6; 50%), los adultos medios (4/10; 40%) y los procedentes del sur de Tierra del Fuego (41,6%) y Santa Cruz/Magallanes (40%). Se registraron correlaciones medias y bajas entre la periodontitis y las diferentes variables relevadas en la cavidad oral, así como con las reacciones periósticas proliferativas. Los resultados indican que una higiene deficiente podría haber influido en el aumento de la enfermedad dental en aquellos individuos con periodontitis.
Alergiczny nieżyt nosa – nowe wyzwania przed sezonem pylenia
Authors: Doniec Zbigniew , Sybilski Adam J.
Published: February 2022

Alergiczny nieżyt nosa (ANN), stan zapalny śluzówek nosa i zatok przynosowych, jest jedną z najczęstszych przewlekłych chorób (dotyczy nawet do 25–35% populacji). Charakterystyczne objawy to: kichanie, świąd i zaczerwienienie nosa, zatkanie nosa, wodnisty wyciek z nosa. Objawy ANN mogą utrudniać koncentrację i prowadzić do problemów z uczeniem się, nieuwagi, drażliwości i zaburzeń nastroju, a nawet problemów społecznych i rodzinnych. Sezonowy ANN jest spowodowany alergenami pyłków drzew, traw, chwastów. Terapia ANN obejmuje profilaktykę, np. ograniczenie aktywności na dworze w okresie pylenia roślin i stosowanie oczyszczaczy powietrza w pomieszczeniach zamkniętych, leczenie farmakologiczne (lekami przeciwhistaminowymi II generacji i donosowymi glikokortykosteroidami) oraz leczenie przyczynowe, jakim jest immunoterapia alergenowa. Podawanie leków przeciwhistaminowych II generacji rozpoczęte przed sezonem pylenia roślin jest bardziej korzystne dla pacjenta niż leczenie rozpoczęte dopiero po wystąpieniu pierwszych objawów choroby. Takie postępowanie jest skorelowane z hamowaniem ekspresji receptora H1 (mRNA H1R) w błonie śluzowej nosa. Najlepszą skuteczność wykazano przy podawaniu leków przeciwhistaminowych 2–4 tygodnie przed sezonem pylenia pyłków. Obecnie zaleca się samoleczenie pacjentów z ANN za pomocą specjalnie stworzonych aplikacji. Takie podejście ma za zadanie przyspieszyć początek terapii oraz ewentualną intensyfikację, w zależności od nasilenia objawów ANN. W przypadku dzieci zawsze należy pamiętać o bezpieczeństwie i ramach rejestracyjnych preparatów. Wiele leków stosowanych u młodzieży i dorosłych nie ma rejestracji u dzieci przedszkolnych. Strategia profilaktycznego, przedsezonowego stosowania antagonistów receptora histaminowego H1 wydaje się obecnie uzasadnioną i atrakcyjną opcją terapeutyczną w leczeniu ANN.

Global climate change also influences the forest damaging agents occurrence and thus a forest health. Forest trees that are damaged by agents are in managed forests processed by salvage felling. The amount of an annual salvage felling represents the occurrence of a damaging agents occurrence in a certain year. In 2015, the area of forests in Slovakia reached 2.014 mil. ha. Within the 20 years (from 1998 to 2017), the total felling reached 162.52 mil. m3, out of this 47.99 % were ascribed to a salvage felling. Abiotic agents were the most damaging agents (42.28 mil. m3 of damaged wood), out of it a wind was the most important one. Biotic damaging agents were the second important group (32.165 mil. m3), whereas bark beetles on spruce were the most important. The third group and the less damaging one was anthropogenic agents group (3.555 mil. m3) with an air pollution as the most important damaging agent. There was no statistically significant difference in the volume of processed trees within salvage felling caused by abiotic and biotic damaging agents. However, these two groups caused significantly higher damages than the third group of anthropogenic damaging agents. There were two major wind damages, Alžbeta in 2004 and Žofia in 2014 with damaged wood 5.3 mil. m3 and 5.2 mil. m3, respectively. They occurred in southern, central and northern part of Slovakia. As damaged wood was not processed from strict nature conservation areas, the secondary damaging agents, mostly Ips typographus on Norway spruce reproduced as much that after some years it cumulatively reached or even exceeded damages from those two major windthrows episodes.
Northern red oak (Quercus rubra L.) as a species suitable for the upcoming seasons with frequent dry periods
Authors: Kupka Ivo , Vopálka-Melicharová Lenka
Published: February 2022

Northern red oak (Quercus rubra L.) has higher tolerance to dry periods and to lower soil nutrient content. It seems to be more resistant to tracheomycosis and therefore it should be considered as a promising species on selected forest sites. The research plots are situated in the Louny region with significant rainfall deficit; good model area for future expected climatic changes. New plantation of northern red oak and sessile oak on together 10 subplots with 500 plants were measured between 2015 and 2019. Results proved significant level (α = 0.05) of better height growth of northern red oak as well as higher resistance to dry periods (lower mortality). Lang’s Rain Factor proved to be a good indicator of difficult climatic condition during growing seasons and therefore could be used for realistic evaluation of possible success or failure of artificial regeneration.
Silviculture as a tool to support stability and diversity of forests under climate change: study from Krkonoše Mountains

Published: February 2022

In Europe, warming, droughts and the rise of extreme climate events have an increasing significant negative effect on forest stands. Therefore, it is necessary to create appropriate adaptation strategies of silviculture to mitigate the impacts of global climate change on forest ecosystems in Central Europe. The objectives of this paper were to evaluate stand production, structure and diversity on eight experimental research plots in the Krkonoše Mountains. Subsequently, three variants of management were compared in mixed stands at the age of 17 – 20 years originating from natural regeneration: A) control variant (stands before thinning), B) applied newly designed thinning in the context of climate change adaptation and C) simulative thinning from below. Number of trees decreased from 3,256 trees ha−1 by 32% after adaptation thinning and by 36% after thinning from below. The basal area decreased in variant B by 22% and in variant C by 12%. Structural diversity and tree species richness increased after application of adaptation thinning, while decrease of diameter differentiation and total diversity was observed after thinning from below. Moreover, horizontal structure changed from aggregated spatial pattern to random distribution after the interventions, especially under adaptation thinning. The newly designed structuralizing adaptation thinning method seems to be a more suitable option in given habitat and stand conditions compared to the commonly performed thinning from below. In future, this issue will certainly require further close cooperation of forestry experts in order to arrive at optimal variants of solutions differentiated according to specific conditions.
Soil erosion in Mediterranean chestnut tree plantations at risk due to climate change and land abandonment

Published: February 2022

Chestnut cultivation is a type of traditional centennial exploitation in southern areas of Extremadura. Currently, chestnut is in danger of extinction due to the effects of climate change, some diseases (e.g. Cryphonectria parasitica) and land mismanagement. The high temporal variability of rainfall leads to soil erosion in chestnut cultivation. New forms of management are proposed to try, among other things, to reduce soil losses. This study quantifies soil losses in areas under tree canopies and open areas considering two different age plantations; 1990s and 1960s. To achieve the proposed goal 18 erosion plots were installed as paired plots under tree canopies and open areas in both plantations. The total amount of rainfall per event, tree cover, bare soil, runoff coefficient and sediment concentration were also measured in every plot. The results showed that the highest percentage of bare soil (> 45%) coincides with the period of greatest tree cover (> 75%). The open areas and the youngest plantation showed soil losses higher than the areas under the tree and the oldest plantation. In addition, soil losses increase as higher percentages of bare soil are recorded. We conclude that the size of the trees and a better soil stability in older plantations help reduce soil losses.

Published: February 2022

Wood, as a building material, is nowadays more often used outdoors. From the point of view of environment care, wood constructions and use of renewable materials belongs between modern increasing trends in industry. Wooden facades, more often used without surface treatment, are the important part of this trend. In Central Europe, European larch (Larix decidua) and Siberian larch (Larix sibirica) are especially popular materials for wooden facade elements. The aim of this study is to characterize the surface degradation of untreated facade models from both European and Siberian larch wood. The wood species, orientation to the sides of the world and construction type of the facade were the evaluation factors, which were regularly examined during 24 months of outdoor exposure via measuring the changes of surface colour, gloss, wettability and visual appearance in the form of cracks and resin leaking. The influence of all evaluated factors on the measured properties was determined. The results of this work can help to proper use of untreated larch wood on facade elements in practice.

Increasing knowledge of the gut microbiota and its interference in human homeostasis in recent years has contributed to a better understanding of number of different interactions occurring in the gastrointestinal tract. Disruption of the microbiota is detrimental to health and contributes to the development of numerous diseases and may also be an accelerator of pathophysiological processes such as atherosclerosis. Cardiovascular diseases are the most common cause of death worldwide, so the development of new methods to support the treatment and prevention of these diseases becoms one of the priorities of modern medicine. Probiotics may constitute an important element of support in the treatment and prevention of CVD (cardiovascular diseases). A number of papers support such a statement, however, larger clinical trials are needed. Through a number of mechanisms including mitigating inflammation, sealing the intestinal epithelium, and affecting metabolism, probiotics may have a beneficial effect on general health and slow down the pathogenesis of many diseases, including those affecting the cardiovascular system. This article contains a review of current discoveries on the role of probiotics in the prevention and support of CVD treatment.

Authors: Lyu Yushuang , Yin Muqi , Xi Fangjie , Hu Xiaojun
Published: February 2022

Purpose

This study explores the underlying research topics regarding CRISPR based on the LDA model and figures out trends in knowledge transfer from science to technology in this area over the latest 10 years.

Design/methodology/approach

We collected publications on CRISPR between 2011 and 2020 from the Web of Science, and traced all the patents citing them from lens.org. 15,904 articles and 18,985 patents in total are downloaded and analyzed. The LDA model was applied to identify underlying research topics in related research. In addition, some indicators were introduced to measure the knowledge transfer from research topics of scientific publications to IPC-4 classes of patents.

Findings

The emerging research topics on CRISPR were identified and their evolution over time displayed. Furthermore, a big picture of knowledge transition from research topics to technological classes of patents was presented. We found that for all topics on CRISPR, the average first transition year, the ratio of articles cited by patents, the NPR transition rate are respectively 1.08, 15.57%, and 1.19, extremely shorter and more intensive than those of general fields. Moreover, the transition patterns are different among research topics.

Research limitations

Our research is limited to publications retrieved from the Web of Science and their citing patents indexed in lens.org. A limitation inherent with LDA analysis is in the manual interpretation and labeling of “topics”.

Practical implications

Our study provides good references for policy-makers on allocating scientific resources and regulating financial budgets to face challenges related to the transformative technology of CRISPR.

Originality/value

The LDA model here is applied to topic identification in the area of transformative researches for the first time, as exemplified on CRISPR. Additionally, the dataset of all citing patents in this area helps to provide a full picture to detect the knowledge transition between S&T.
Academic Collaborator Recommendation Based on Attributed Network Embedding
Authors: Du Ouxia , Li Ya
Published: February 2022

Purpose

Based on real-world academic data, this study aims to use network embedding technology to mining academic relationships, and investigate the effectiveness of the proposed embedding model on academic collaborator recommendation tasks.

Design/methodology/approach

We propose an academic collaborator recommendation model based on attributed network embedding (ACR-ANE), which can get enhanced scholar embedding and take full advantage of the topological structure of the network and multi-type scholar attributes. The non-local neighbors for scholars are defined to capture strong relationships among scholars. A deep auto-encoder is adopted to encode the academic collaboration network structure and scholar attributes into a low-dimensional representation space.

Findings

1. The proposed non-local neighbors can better describe the relationships among scholars in the real world than the first-order neighbors. 2. It is important to consider the structure of the academic collaboration network and scholar attributes when recommending collaborators for scholars simultaneously.

Research limitations

The designed method works for static networks, without taking account of the network dynamics.

Practical implications

The designed model is embedded in academic collaboration network structure and scholarly attributes, which can be used to help scholars recommend potential collaborators.

Originality/value

Experiments on two real-world scholarly datasets, Aminer and APS, show that our proposed method performs better than other baselines.

The Relation between Accountability and the Climate of Service in Israeli Public organisations
Authors: ELIYA Yehuda , BIBU Nicolae
Published: February 2022

The paper discusses the findings of a doctoral research project about the relation between accountability and the climate of service in Israeli public organizations. It used a quantitative approach and targeted a number of 2798 respondents. The research population included managers and employees from six public organizations from Israel in autumn 2018l. The final sample comprised 1036 valid questionnaires. The four hypothesis related to the topic were validated, and a positive correlation was found between accountability and service climate. It should be noted that the organization's “general accountability” showed weak correlation with “service climate”. The conclusions point out that accountability of public organizations and of their employees is perceived as an important factor for enhancing the service climate in the public organizations, for increasing the citizen's confidence and creating public system fairness.

Like any other industry, transport faces major changes. This fact implies risks, but - at the same time – great opportunities for improvement and development. The triggers of change come from area of technology, customer’s fast changing requirements and new industry actors that disrupt traditional business models. This study is aimed to achieve two of these aspects: the requirements of retail customers (contractual conditions agreed with the suppliers of transport for distribution to the stores) and the impact of the new technologies. This article focus is on the main conditions that develops new skills and competencies for service companies and remodels the processes according to new technologies. The current analysis ‘scope is to highlight the future trends of the relations between the customer and the carriers and the additional competences they will have to acquire on the Romanian market. The used research method was contract analysis and interviews with participating companies.
Glycosylation in cancer and infection : the role of sialic acid
Authors:   , Zhang Yuecheng
Published: February 2022

Sialic acids (SA), a group of nine-carbon backbone monosaccharides are abundantly expressed in vertebrates. They are usually linked to the terminal of glycan chains and play crucial roles in many biological processes, including cell adhesion, cell-cell interactions, immune modulation, cancer cell migration and invasion, as well as viral infections. To analyze and monitor SA expression, antibodies and glycan-binding lectins are typically used. However, high costs and poor stability limit the application in SA analysis. To overcome these drawbacks, an imprinting technique was used to synthesize an alternative SA receptor – SA molecularly imprinted polymers (SA-MIPs). Fluorescent molecules are embedded into the MIPs, facilitating the detection of MIPs binding to cells by flow cytometry and fluorescence microscopy. Firstly, core-shell SA imprinted MIPs were used to analyze SA expression in a panel of breast cancer cell lines. The SA expression of these cell lines was also tested by using the two glycan-binding lectins, MAL andSNA, which recognize α2,3 and α2,6 SA, respectively. Our results show that breast cancer cell lines express α2,3 and α2,6 SA dissimilarly, and hence present different SA-MIP binding patterns. The specificity of SA-MIPs was further verified by an inhibition assay using two pentavalent SA conjugates that interfere with the SAMIPs.Furthermore, the SA-MIP synthesis protocol has been improved by using silica-coated polystyrene particles. The polystyrene core particles are lighter and smaller, increasing MIP suspensibility and augmenting MIP-cancer cell interactions. The cancer cell binding properties and the specificity have been verified by using thirteen different cancer cell lines, showing that the SA-MIPs can be used as effective tools for SA expression analysis. The SA-MIPs were used to analyze the SA expression of in vitro cultured cells treated with soluble cytokines to mimic the tumor microenvironment. The SA expression of two cancer cell lines stimulated with soluble cytokines was analyzed by using lectins and SA-MIPs. The MIPbinding data correlated well with lectin staining results, demonstrating the potential of SA-MIPs to be used in the analysis of overexpressed SA in the tumor microenvironment. Furthermore, the involvement of SA in the infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was assessed. The viral surface receptor-binding domain (RBD) recognizes and conjugates with receptors on host cells, triggering the infection. Although the interaction between the RBD and host cells has been extensively studied, the mechanism behind this reaction is not fully determined. In this study, the interaction between the viral RBD and a panel of human cell lines from tissues susceptible to viral infection was tested. Moreover, the role of SA in this interaction has also been tested and evaluated.
