Abstract. Iskandar BS, Iskandar J. 2021. Kawung: Landraces, management, uses, and conservation based on moral versus economic interest among Outer Baduy community, South Banten, Indonesia. Biodiversitas 22: 5572-5584. The sugar palm or kawung (Arenga pinnata (Wurm) Merr.) has naturally or semi naturally grown in many rural areas of Banten and West Java. The sugar palm has social, economic, cultural, and ecological benefits for rural communities, but its population has dramatically decreased. This study aimed to access the knowledge, traditional management, uses and traditional conservation of sugar palm. This research used a qualitative method with an ethnoecological approach. The results showed that the Outer Baduy community has a rich knowledge of sugar palm. Two landraces of sugar palm are recognized by Outer Baduy mainly kawung gedé and kawung salompét. They have not intensively cultivated the sugar palm, but managed the kawung seedlings which grow naturally or assisted by civet or careuh in traditional agroforestry systems, including huma, reuma, leuweung lembur, and leuweung kolot. The weeds growing surrounding the seedlings are cleared, and then the seedlings will grow naturally and finally develop to mature trees. The sugar palm has been traditionally used for ecological, socio-economic, and cultural functions. The Outer Baduy community has traditionally conserved the sugar palm which grows in traditional agroforestry systems. The sugar palm trees, fruits, and the stems have never been cut, used as the sweetmeats, and made into sago flour, respectively, while the civets which have assisted distribution and regeneration of the sugar palm have never been hunted, and their habitat has never been destroyed.

Abstract. Djeddar H, Boudjelida H, Arroussi DER. 2021. New alternative for culicidian fauna control using Borago officinalis and Drimia maritima plant extracts. Biodiversitas 22: 5688-5694. Focus on the development of insecticides based on botanical extracts may represent an alternative environmentally interesting tool to chemical control. The current study aimed to investigate the effects of both extracts of Drimia maritima (Asparagales: Asparagaceae) and Borago officinalis (Lamiales: Boraginaceae) on larvae sensibility, physiological and biochemical parameters of Culex pipiens (Diptera: Culicidae). The larvicidal bioassay exhibits a significant dose-response relationship against the fourth instar larvae of Cx. pipiens. Moreover, biochemical analyses revealed a decrease in proteins levels, carbohydrates and lipids in the whole larvae body treated with the lethal concentrations (LC50, LC90) of D. maritima extract as compared to the control series. Whereas, using B. officinalis herbal plants, the result showed a decrease in lipid and carbohydrate contents and an increase in protein. The ability of D. maritima and B. officinalis extracts to inhibit acetylcholinesterase (AChE) activity in a whole body of the treated larvae of Cx. pipiens is examined. The estimated specific activity of glutathione S-transferase (GST) at different times was significantly increased under the effects of both plants. The present study demonstrates that the aqueous extracts of D. maritima and B.officinalis present insecticidal properties with neurotoxic effects against larval stages of the domestic mosquito Cx. pipiens. In this context, the use of chemical insecticides for mosquito control is no longer recommended and the alternatives of eco-friendly products are encouraged.

Abstract. Paiva Maia AC, da Costa Ferreira E, Marques de Lucena C, dos Santos Souza A, Dias da Cruz D, Paiva de Lucena RF. 2021. Comparing ethnobotanical knowledge of medicinal plants between community health workers and local experts in the “Mata da Paraíba” zone, northeastern Brazil. Biodiversitas 22: 5606-5616. The use of medicinal plants is an old practice in a society that has been transmitted to this day, with local experts recognized in many communities and being encouraged through public policies. In Brazil, Community Health Agents (CHWs) can be important for the dissemination of this practice, due to their work with the Health System and the community. This study aimed to compare the knowledge of medicinal plants between CHWs and local experts in the community of Timbó, the municipality of Jacaraú (Paraíba, northeastern Brazil). Semi-structured interviews were conducted addressing local names of plants, their indications, parts used, and preparation methods. The data on the species local importance were analyzed through the use value (UV) and relative importance (RI) methods. Local experts cited more species than CHWs. There was great local importance of some species both among local specialists and among CHWs. However, some species were highlighted exclusively among local specialists. Decoction and infusion stood out among the preparation methods and leaf, flower, and seed were the most prominent parts used. The diseases treated with plants are mainly related to the respiratory and digestive systems. Our findings show a correspondence between the CHWs’ knowledge and local experts’ knowledge, which leads us to believe that experts and CHWs may be sharing the same local knowledge in the study community.
The Effect of Kerf Thickness on Hardwood Log Recovery
Authors: Thomas R. Edward , Buehlmann Urs
Published: February 2022

When sawing a log into lumber or other products, the saw blade removes material to separate the wood fibers between the resulting two parts, a loss of material that is commonly referred to as saw kerf. Thicker kerfs result in greater waste and less material available to produce lumber. Over the past decades, with the advancement of materials and technology, saw blade thickness has decreased. However, the reduction in material loss owing to a reduction in saw kerf may not always translate into a statistically significant increase in lumber product recovery. In this study, we explored the effect of saw kerf thickness on lumber recovery for a range of hardwood log diameters using the US Forest Service's Log Recovery Analysis Tool (LORCAT) sawmill simulation tool. Results indicate that the recovery gains realized depend upon the log diameters sawn, the lumber target thickness, and the change (reduction) in the thickness of the saw kerf.

Developmental defects of enamel and dental anomalies in five-year-old cleft patients
Authors: Agel Mona , Vaidyanathan Mina , Bhujel Nabina
Published: February 2022

INTRODUCTION

Children born with cleft lip and/or palate (CLP) have a higher prevalence of developmental defects of enamel and dental anomalies, and are at an increased risk of developing dental caries. The aim of this study was to establish the prevalence of dental anomalies and developmental defects of enamel in children born with CLP, and to assess compliance with dental prevention.

METHODS

Data were collected retrospectively for children who attended the five-year-old dental review clinic at the South Thames cleft service over a four-year period. Records of 162 children were analysed.

RESULTS

Unilateral CLP was the most common type of cleft. Two-thirds (65%) of the children in this service evaluation had developmental defects of enamel affecting the upper incisors. A third (32%) had enamel hypomineralisation. Between 90% and 100% of children over the four-year study period were registered with a dentist. Regular fluoride varnish application was received by 64% to 81% of children and toothpaste with an appropriate concentration of fluoride was used by 72% to 91% of children.

CONCLUSIONS

Improvements in shared care arrangements between primary dental care clinicians and specialist paediatric dentists are needed to ensure that caries risk is reduced in children born with CLP. This allows the specialist dental services to focus on the complex dental issues that are seen more frequently in CLP and often require a multidisciplinary approach.

Integrated and stable microlasers are indispensable building blocks of micro-photonics. Here, we report the realization of an ytterbium-doped lithium niobate microring laser operating in the 1060-nm band under the pump of a 980-nm-band laser. The monolithic laser has a low threshold of 59.32 µW and relatively high output power of 6.44 µW, a state-of-the-art value for rare-earth ions-doped lithium niobate thin-film lasers. The monolithic laser with desirable performance and attractive scalability may find many applications in lithium niobite photonics.

Published: February 2022

Background

Culex pipiens quinquefasciatus Say(Cx.quinquefasciatus) andCulex pipiens form molestus Forskal(Cx.molestus) in theCulex pipiens complexgroup show considerable differences in host seeking, blood feeding, mating behavior and in vector competence. Blood-feeding mosquito behaviors are closely related to their olfactory gene expression and olfactory gene repertoire composition. Comparing olfactory genes between these two subspecies with significantly different blood-feeding behaviors can support further research on the molecular mechanism of theCulex pipiens complexolfactory sensory system, providing a new approach for determining candidate attractant or repellent compounds.

Methods

Non-blood-feeding (NBF) and post-blood-feeding (PBF) olfactory system transcriptomes of the two subspecies were sequenced, and the biological functions of their differentially expressed genes were described by bioinformatics analysis. A quantitative polymerase chain reaction (qPCR) was applied to validate the RNA-seq data. The roles of particular olfactory receptors inCx.quinquefasciatusblood-feeding behaviors were evaluated by RNAi.

Results

Five, 7, 24, and 3Cx.quinquefasciatus-specific OBPs,Cx.molestus-specific OBPs,Cx.quinquefasciatus-specific ORs andCx.molestus-specific ORs were identified, respectively. The majority of selected ORs were consistent with the predicted transcriptome sequencing results after qRT-PCR validation. OR5 was expressed only inCx.quinquefasciatus, and OR65 was the only gene upregulated after blood feeding inCx.molestus. The blood-feeding rates of the OR5 and OR78 dsRNA groups were significantly lower (4.3%±3.1% and 13.3%±11.5%) than those of the enhanced green fluorescence protein (EGFP) group (64.5%±8.7%).

Conclusion

Most OBPs and ORs were expressed in both subspecies but showed divergence in expression level. OR5 and OR65 might be species-specific expressed genes that regulate the olfactory behaviors ofCx.quinquefasciatusandCx.molestus, respectively. The RNA interference of OR5 and OR78 could inhibit the blood-feeding behavior ofCx.quinquefasciatus, providing new targets for screening effective repellent compounds to control mosquito-borne diseases effectively and efficiently.

Published: February 2022

Background

Working under pandemic conditions exposes health care workers (HCWs) to infection risk and psychological strain. A better understanding of HCWs’ experiences of following local infection prevention and control (IPC) procedures during COVID-19 is urgently needed to inform strategies for protecting the psychical and psychological health of HCWs. The objective of this study was therefore to capture the perceptions of hospital HCWs on local IPC procedures and the impact on their emotional wellbeing during the first wave of the COVID-19 pandemic in Europe.

Methods

Participants were recruited in two sampling rounds of an international cross-sectional survey. Sampling took place between 31 March and 17 April 2020 via existing research networks and between 14 May and 31 August 2020 via online convenience sampling. Main outcome measures were behavioural determinants of HCWs’ adherence to IPC guidelines and the WHO-5 Well-Being Index, a validated scale of 0–100 reflecting emotional wellbeing. The WHO-5 was interpreted as a score below or above 50 points, a cut-off score used in previous literature to screen for depression.

Results

2289 HCWs from 40 countries in Europe participated. Mean age was 42 (±11) years, 66% were female, 47% and 39% were medical doctors and nurses, respectively. 74% (n = 1699) of HCWs were directly treating patients with COVID-19, of which 32% (n = 527) reported they were fearful of caring for these patients. HCWs reported high levels of concern about COVID-19 infection risk to themselves (71%) and their family (82%) as a result of their job. 40% of HCWs considered that getting infected with COVID-19 was not within their control. This feeling was more common among junior than senior HCWs (46% versus 38%,Pvalue < .01). Sufficient COVID-19-specific IPC training, confidence in PPE use and institutional trust were positively associated with the feeling that becoming infected with COVID-19 was within their control. Female HCWs were more likely than males to report a WHO-5 score below 50 points (aOR 1.5 (95% confidence interval (CI) 1.2–1.8).

Conclusions

In Europe, the COVID-19 pandemic has had a differential impact on those providing direct COVID-19 patient care, junior staff and women. Health facilities must be aware of these differential impacts, build trust and provide tailored support for this vital workforce during the current COVID-19 pandemic.
Elucidating the material basis and potential mechanisms of Ershiwuwei Lvxue Pill acting on rheumatoid arthritis by UPLC-Q-TOF/MS and network pharmacology

Published: February 2022

Ershiwuwei Lvxue Pill (ELP, མགྲིན་མཚལ་ཉེར་ལྔ།), a traditional Tibetan medicine preparation, has been used hundreds of years for the clinical treatment of rheumatoid arthritis (RA) in the highland region of Tibet, China. Nevertheless, its chemical composition and therapeutic mechanism are unclear. This study aimed to uncover the potentially effective components of ELP and the pharmacological mechanisms against RA by combing UPLC-Q-TOF/MS and network pharmacology. In this study, 96 compounds of ELP were identified or tentatively characterized based on UPLC-Q-TOF/MS analysis. Then, a total of 22 potential bioactive compounds were screened by TCMSP with oral bioavailability and drug-likeness. Preliminarily, 10 crucial targets may be associated with RA through protein-protein interaction network analysis. The functional enrichment analysis indicated that ELP exerted anti-RA effects probably by synergistically regulating many biological pathways, such as PI3K-Akt, Cytokine-cytokine receptor interaction, JAK-STAT, MAPK, TNF, and Toll-like receptor signaling pathway. In addition, good molecular docking scores were highlighted between five promising bioactive compounds (ellagic acid, quercetin, kaempferol, galangin, coptisine) and five core targets (PTGS2, STAT3, VEGFA, MAPK3, TNF). Overall, ELP can exert its anti-RA activity via multicomponent, multitarget, and multichannel mechanisms of action. However, further studies are needed to validate the biological processes and effect pathways of ELP.

Published: February 2022

Early recognition of the clinical signs of bloodstream infection in pediatric burn patients is key to improving survival rates in the burn unit. The objective of this study was to propose a simple scoring criteria that used readily available temperature, heart rate (HR) and mean arterial pressure (MAP) data to accurately predict bloodstream infection in pediatric burn patients. A retrospective chart review included 100 patients admitted to the pediatric burn unit for >20% total body surface area (TBSA) burn injuries. Each patient had multiple blood culture tests, and each test was treated as a separate and independent “infection event” for analysis. The time at each blood culture draw was time 0 for that event, and temperature, HR and MAP data was collected for 24 hours after the blood culture was drawn. “Infection events” included in this study had at least six complete sets of temperature, HR and MAP data entries. Median temperature, HR and MAP, as well as mean fever spikes, HR spikes and MAP dips, were compared between infection group (positive blood cultures) and control group (negative blood cultures). These vital sign fluctuations were evaluated individually and as a combination of all three as timely predictors of bloodstream infection. In addition, we tested the prediction of Gram-negative bacteria versus Gram-positive or fungi present in blood cultures. Patients in the infection group had significantly higher median temperatures (p<0.001), mean fever spikes (p<0.001) and mean HR spikes (p<0.001), compared to the control group. Using the combination scoring criteria to predict bloodstream infection, the strongest predictive values in the 24-hour timeframe had high sensitivity (93%) and specificity (81%). The predictive test metric based on vital sign spikes predicted Gram-negative bacteria, but with limited sensitivity (57%) and specificity (44%). A simple scoring criteria using a combination of fever spikes, HR spikes and MAP dips predicted bloodstream infection in pediatric burn patients, and can be feasibly implemented in routine clinical care. There is also potential to use the predictive metric to detect a few select organisms based on vital signs, however further work is necessary to enhance accuracy to levels that would allow consideration for clinical use.

Published: February 2022

Stable isotope ratios are used to reconstruct animal diet in trophic ecology via mixing models. Several assumptions of stable isotope mixing models are critical, i.e., constant trophic discrimination factor and isotopic equilibrium between the consumer and its diet. The isotopic turnover rate (λ and its counterpart the half-life) affects the dynamics of isotopic incorporation for an organism and the isotopic equilibrium assumption: λ involves a time lag between the real assimilated diet and the diet estimated by mixing models at the individual scale. Current stable isotope mixing model studies consider neither this time lag nor even the dynamics of isotopic ratios in general. We developed a mechanistic framework using a dynamic mixing model (DMM) to assess the contribution of λ to the dynamics of isotopic incorporation and to estimate the bias induced by neglecting the time lag in diet reconstruction in conventional static mixing models (SMMs). The DMM includes isotope dynamics of sources (denotedδs), λ and frequency of diet-switch (ω). The results showed a significant bias generated by the SMM compared to the DMM (up to 50% of differences). This bias can be strongly reduced in SMMs by averaging the isotopic variations of the food sources over a time window equal to twice the isotopic half-life. However, the bias will persist (∼15%) for intermediate values of theω/λ ratio. The inferences generated using a case study highlighted that DMM enhanced estimates of consumer’s diet, and this could avoid misinterpretation in ecosystem functioning, food-web structure analysis and underlying biological processes.

Shared medical appointments (SMAs) offer a means for providing knowledge and skills needed for chronic disease management to patients. However, SMAs require a time and attention investment from health care providers, who must understand the goals and potential benefits of SMAs from the perspective of patients and providers. To better understand how to gain provider engagement and inform future SMA implementation, qualitative inquiry of provider experience based on a knowledge-attitude-practice model was explored. Semi-structured interviews were conducted with 24 health care providers leading SMAs for heart failure at three Veterans Administration Medical Centers. Rapid matrix analysis process techniques including team-based qualitative inquiry followed by stakeholder validation was employed. The interview guide followed a knowledge-attitude-practice model with a priori domains of knowledge of SMA structure and content (understanding of how SMAs were structured), SMA attitude/beliefs (general expectations about SMA use), attitudes regarding how leading SMAs affected patients, and providers. Data regarding the patient referral process (organizational processes for referring patients to SMAs) and suggested improvements were collected to further inform the development of SMA implementation best practices. Providers from all three sites reported similar knowledge, attitude and beliefs of SMAs. In general, providers reported that the multi-disciplinary structure of SMAs was an effective strategy towards improving clinical outcomes for patients. Emergent themes regarding experiences with SMAs included improved self-efficacy gained from real-time collaboration with providers from multiple disciplines, perceived decrease in patient re-hospitalizations, and promotion of self-management skills for patients with HF. Most providers reported that the SMA-setting facilitated patient learning by providing opportunities for the sharing of experiences and knowledge. This was associated with the perception of increased comradery and support among patients. Future research is needed to test suggested improvements and to develop best practices for training additional sites to implement HF SMA.

Introduction

Pregnant women are at increased risk for COVID-19, and COVID-19 vaccine is the most promising solution to overcome the current pandemic. This study was conducted to evaluate pregnant women’s perceptions and acceptance of COVID-19 vaccination.

Materials & methods

A cross-sectional study was conducted from February 18 to April 5 2021. An anonymous survey was distributed in 7 French obstetrics departments to all pregnant women before a prenatal visit. All pregnant women attending a follow-up consultation were asked to participate in the study. An anonymous web survey was available through a QR code and participants were asked whether or not they would agree to be vaccinated against SARS-CoV-2, and why. The questionnaire included questions on the patients’ demographics and their knowledge of COVID-19 vaccines.

Results

Of the 664 pregnant women who completed the questionnaire, 29.5% (95% CI 27.7; 31.3) indicated they would agree to be vaccinated against COVID-19. The main reason for not agreeing was being more afraid of potential side effects of the SARS-CoV-2 vaccine on the fetus than of COVID-19. Factors influencing acceptance of vaccination were: being slightly older, multiparity, having discussed it with a caregiver and acceptance of the influenza vaccine.

Discussion

Nearly one-third of pregnant women in this population would be willing to be vaccinated. In addition to studies establishing fetal safety, public health agencies and healthcare professionals should provide accurate information about the safety of COVID-19 vaccines.
Study on temporal and spatial differentiation of biocapacity in Shenyang from a multi-scale perspective
Authors: Gao Yanpeng , Chen Wenjun , Guo Chunyao
Published: February 2022

Biocapacity of a region exhibits spatial differences owing to the limitations of regional scale and natural conditions. Based on the multi-scale perspective, we comprehensively studied and analyzed the temporal and spatial differences of the biocapacity of a region in an attempt to establish the groundwork for optimizing urban development and its utilization framework. By adopting the ecological footprint model along with multi-scale difference evaluation method, the municipal and county scales are incorporated into a unified analysis framework in this paper, thereby facilitating the exploration of the temporal and spatial differences in the biocapacity of Shenyang—a city in China—from 2005 to 2019. The results demonstrated that: 1) At the municipal scale, the biocapacity per capita fluctuated between 1.35 hm2/person and 2.22 hm2/person. It revealed an “up-down-up” trend, which appeared consistent with the Kuznets cycle; at the county scale, the biocapacity depicted spatial differences, while those of downtown and surrounding districts/counties developed a two-level ascending hierarchical structure. 2) The time series of footprint size and depth first ascended and then declined, and can be classified into four types: closed type, inverted U-type, S-type, and M-type. Among them, S-type and M-type have the phenomenon of over-utilizing the stock capital. 3) For a long time, the regional difference of biocapacity has mostly dwelt on two scales with an evident scale effect, and the biocapacity of Liaozhong District was the worst.
Medical rehabilitation of older employees with migrant background in Germany: Does the utilization meet the needs?
Authors: Schröder Chloé Charlotte , Breckenkamp Jürgen , du Prel Jean-Baptist
Published: February 2022

Due to demographic change with an ageing workforce, the proportion of employees with poor health and a need for medical rehabilitation is increasing. The aim was to investigate if older employees with migrant background have a different need for and utilization of medical rehabilitation than employees without migrant background. To investigate this, self-reported data from older German employees born in 1959 or 1965 of the first and second study wave of the lidA cohort study were exploratory analyzed (n = 3897). Subgroups of employees with migrant background were separated as first-generation, which had either German or foreign nationality, and second-generation vs. the rest as non-migrants. All subgroups were examined for their need for and utilization of medical rehabilitation with descriptive and bivariate statistics (chi-square, F- and post-hoc tests). Furthermore, multiple logistic regressions and average marginal effects were calculated for each migrant group separately to assess the effect of need for utilization of rehabilitation. According to our operationalizations, the foreign and German first-generation migrants had the highest need for medical rehabilitation while the German first- and second-generation migrants had the highest utilization in the bivariate analysis. However, the multiple logistic model showed significant positive associations between their needs and utilization of rehabilitation for all subgroups. Further in-depth analysis of the need showed that something like under- and oversupply co-exist in migrant groups, while the foreign first-generation migrants with lower need were the only ones without rehabilitation usage. However, undersupply exists in all groups independent of migrant status. Concluding, all subgroups showed suitable use of rehabilitation according to their needs at first sight. Nevertheless, the utilization does not appear to have met all needs, and therefore, the need-oriented utilization of rehabilitation should be increased among all employees, e.g. by providing more information, removing barriers or identifying official need with uniform standards.

Análisis estratégico de un recurso patrimonial territorial: los refugios antiaéreos de la Guerra Civil española en la provincia de Girona (Cataluña)
Authors: González Vázquez David , Abulí Vergés Oriol , Besolí Martín Andrés
Published: February 2022

El presente artículo tiene como objetivo el análisis estratégico turístico de los refugios antiaéreos de la Guerra Civil española (1936-1939), y su capacidad factual y potencial de turistización. El estudio se centra en el caso de la provincia catalana de Girona, territorio con unas especificidades históricas y geográficas que han propiciado una situación singular en la conservación de este valioso conjunto patrimonial cultural. La investigación incluye un estado de la cuestión sobre el problema y una aproximación metodológica de carácter cualitativo mediante la matriz de análisis DAFO, y las técnicas de trabajo de campo y entrevista informal no estructurada a expertos en el tema y personal técnico de la administración local. El trabajo propugna que los refugios antiaéreos constituyen una categoría relevante, bien definida y estudiada dentro de los vestigios patrimoniales de la Guerra Civil, cuya valorización turística en la zona es aún escasa, pero con un enorme potencial de crecimiento. En este sentido, se valida la hipótesis de partida y se concluye que dicho crecimiento requiere de una gestión estratégica territorial integral, inexistente hasta la fecha, que involucre a todos los agentes turísticos y culturales implicados en la gestión y puesta en valor de este extenso conjunto patrimonial en la provincia de Girona.
Luís Bolín y el turismo en España entre 1928 y 1952
Authors: Valero Escandell José Ramón
Published: February 2022

El libro analiza el turismo español entre 1928 y 1952 utilizando como hilo conductor la figura de Luís Bolín, político franquista que asumió cargos de responsabilidad creciente a lo largo de aquellos años, comprendidos entre la puesta en marcha del Patronato Nacional de Turismo (PNT), donde asumió la gestión en la zona sur del país, hasta sus años al frente de la Dirección General de Turismo, sin olvidar su papel durante la Guerra Civil en la que impulsó el Servicio Nacional de Turismo del bando franquista y las novedosas rutas de guerra. No se trata esencialmente de un libro de carácter biográfico, aunque también refleja bastantes detalles de su vida, y tampoco tiene por objeto analizar el papel activo que desempeñó en otros aspectos esenciales de nuestra historia, como su participación destacada en el traslado de Franco desde Canarias a Marruecos gestionando la llegada a Canarias del Dragón Rapide.
Patrimonio cultural inmaterial y turismo. Análisis de la producción científica publicada en revistas Iberoamericanas de turismo
Authors: Soto-Cáceda Delia Rosa , Alberca-Sialer Fabrizio Augusto
Published: February 2022

El turismo basado en el patrimonio cultural inmaterial (PCI) viene ganando protagonismo dentro de las prácticas turísticas actuales, al igual que en los estudios turísticos. En ese sentido, el presente estudio bibliométrico se plantea caracterizar la producción y publicaciones en revistas de turismo iberoamericanas para conocer los avances y vacíos de la investigación sobre PCI. Se analizaron 57 artículos procedentes de 10 revistas de turismo. Se identificó que, pese a que el turismo cultural patrimonial es tendencia mundial, las publicaciones aquí analizadas no lo reflejan. Las publicaciones regionales hacen honor a su ámbito geográfico tanto en la procedencia de sus autores como en los temas tratados, lo que da a este trabajo una mirada netamente regional. No existe una tendencia marcada de publicaciones ni de autores que se dediquen a la investigación y publicación sistemáticas sobre PCI en su relación con el turismo. Brasil y España sobresalen como los países más prolíficos en cuanto a cantidad de autores e instituciones afiliadoras, y sobresalen también los temas relacionados al uso turístico del patrimonio, la educación patrimonial y los impactos del turismo. Estos resultados permiten a investigadores en turismo o PCI ubicar artículos especializados sobre Iberoamérica y a editores de las revistas regionales de turismo reconocer la carencia de artículos sobre PCI, así como la necesidad de publicar en inglés para ganar visibilidad. En adelante, las investigaciones deberán incorporar la recuperación post-covid-19 dentro de un enfoque sostenible del uso turístico del PCI.

Trata-se de um recorte de uma pesquisa de doutorado que buscou cartografar os sentidos das narrativas dos alunos de Ensino Médio da zona rural da Bahia ao desenvolveram práticas pedagógicas que envolvem esse diálogo. Para isso foi realizado uma pesquisa bibliográfica de forma a compor o estado da arte que envolve essas categorias teóricas, tendo como base para esta escrita os anais do EPEA e da ANPed. Concluímos que esse é um campo que necessita de maiores investigações e, desse modo, a pesquisas que envolvem esse diálogo devem ser exploradas ampliando assim o universo formativo da Educação Ambiental e Tecnologias Digitais.

Authors: Faria Jeniffer , Guimarães Mauro
Published: February 2022

Este artigo emerge reflexões sobre a formação de educadores ambientais, em uma perspectiva radical, diante da grave crise socioambiental que se mostra civilizatória. Apresenta-se a proposta teórica-metodológica da ComVivência Pedagógica, explicitando sua base nos cinco princípios formativos e outros elementos que a compõe como o ambiente educativo, a experiência significativa e a potência na transformação do educador como um “Ser mais ambiental”. A partir dos diálogos estabelecidos e dos saberes cocriados no desenvolvimento de experiências formativas anteriores, longe de sermos conclusivos, consolidamos conceitos e elencamos algumas pistas que contribuem para que novas propostas sejam desenvolvidas e suas especificidades possam ser articuladas.

Authors: Chey Samuel W. , Westerhoff Maria , Chey William D.
Published: February 2022

This is the first scientific report describing lymphocytic colitis after administration of the Pfizer severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) messenger RNA (mRNA) vaccine. The patient developed liquid stools, abdominal pain, and nausea within 24 hours of receiving the second dose. Symptoms were persistent for 3 months but improved 113 days after onset. Laboratory profiles and gastrointestinal polymerase chain reaction were normal. Esophagogastroduodenoscopy and colonoscopy performed 98 days after onset revealed patchy erythema in the descending colon and rectosigmoid. Mucosal evaluation revealed lymphocytic colitis. Review of the Vaccine Adverse Event Reporting System revealed 5 cases of microscopic colitis after the second mRNA dose. This report and Vaccine Adverse Event Reporting System cases suggest providers should consider microscopic colitis in the differential diagnosis of patients with severe, persistent diarrhea after the SARS-CoV2 mRNA vaccine.

Ze wzrostem produkcji tworzyw polimerowych gwałtownie zwiększyła się ilość odpadów plastikowych. Problem dotyczy nie tylko akwenów, gdzie odpady z tworzyw tworzą dryfujące wyspy śmieci, ale także plaż i niekontrolowanych wysypisk. Realnym niebezpieczeństwem dla środowiska naturalnego oraz zdrowia ludzi i zwierząt jest tzw. mikroplastik.
School Counsellors’ Perceptions of School Justice and Awareness of Advocacy Duties
Authors: TARHAN Sinem
Published: February 2022

The purpose of this study is to examine school counsellors' awareness of their advocacy responsibilities in relation to distributive, procedural, and interactional justice. The participants in this case study were 14 school counsellors working in secondary schools. They were selected using criterion sampling and maximum variation. Research data were collected using a semi-structured interview form and analyzed using content analysis. According to the findings, school counsellors described their school environments as fair considering the democratic attitudes of principals and teachers. Participating counsellors reported that students complain about various issues regarding favoritism, discriminatory attitudes, problematic communication, and unfair grading. They also reported that when students experience injustice at school, they show emotional reactions such as anger, unhappiness, and helplessness, in addition to aggression towards teachers, school objects, or themselves. School counsellors stated that they encourage such students to share their feelings, claim their rights, and talk to their teachers. However, school counsellors who encouraged students to claim their rights rarely talked to teachers to solve such problems. It can be said that school counsellors who strive to prevent student victimization have played a mediating role rather than being an advocate. Future studies can explore the advocacy practices at private and public schools.
Teacher Empowerment Strategies: Reasons for Nonfulfillment and Solution Suggestions
Authors: CALISICI CELIK Naciye , KIRAL Bilgen
Published: February 2022

This research was carried out to determine the empowerment strategies school principals should implement and the reasons for not being empowering. It was conducted with four elementary school teachers and four school principals in a city in the Aegean Region in the 2017-2018 academic year. In the study, descriptive phenomenology design, one of the qualitative research designs, was used. According to the results, it was revealed that the empowerment strategies to be implemented by school principals were classified under the categories of physical and psychological support, communication, school functioning, and teacher autonomy. The reasons for not making teacher empowerment by school principals were determined as personal, administrative, financial, and limited authority reasons. What the Ministry of National Education should do for teacher empowerment was revealed. They should adopt policies that support personal development and teacher autonomy, increase the authority of school principals, and make changes in the legislation. Following the findings, various suggestions were made on such issues as increasing financial resources that hinder empowerment.

Článek představuje výsledky položkové analýzy oborových testů z chemie zadávanýchpro účely přijímacího řízení na Přírodovědecké fakultě Univerzity Karlovy v letech2016 až 2019. Cílem položkové analýzy, která byla zaměřena na úlohy z obecné chemie,bylo odhalit úlohy, které byly pro uchazeče o studium nejvíce obtížné a úlohynecitlivé tedy takové úlohy, které nedostatečně rozlišovaly úspěšné uchazeče od uchazečůneúspěšných. Obtížné úlohy byly identifikovány na základě vypočtení indexuobtížnosti. Necitlivé úlohy byly stanoveny na základě výpočtu koeficientů ULI(1/2)a RIR. Výsledky položkové analýzy odhalily, že pro uchazeče obtížným tématem je stavovárovnice ideálního plynu. Dále byla odhalena čtyři témata, která obsahovala alespoňjednu obtížnou úlohu (výpočet pH, elektronová konfigurace, iontový součin vodya elektrolýza). Necitlivé úlohy byly detekovány u třech témat (tepelný rozklad látky,rychlostní rovnice a chemické rovnováhy). Necitlivost úlohy často souvisela s vysokýmpočtem kroků nutných k jejímu úspěšnému vyřešení.

Heavy metal (HM) pollution is a severe and common environmental problem in mining area soil. It is imperative to understand the micro ecological characteristics of mining area soil for HM contaminated soil remediation. This study described the effects of HM pollution level and soil physical and chemical parameters on microbial diversity. In this study, high-throughput sequencing technology was used to study the effects of HM pollution on the diversity and composition of the soil microbial community. The soil groups were barren, exhibiting alkaline pH, low total nitrogen (TN), and total potassium (TK) according to soil fertility standard. Compared with the control group, there was severe multiple HM pollution in the other five groups, including lead (Pb), cadmium (Cd), zinc (Zn), and copper (Cu). The dominant phyla accounting for more than 1% of the overall community in all soil groups were Proteobacteria (34.432 ± 7.478%), Actinobacteria (22.947 ± 4.297%), Acidobacteria (10.47 ± 2.439%), Chloroflexi (7.89 ± 2.980%), Planctomycetota (5.993 ± 1.558%), Bacteroidota (4.275 ± 1.980%), Cyanobacteria (3.478 ± 2.196%), Myxococcus (2.888 ± 0.822%), Gemmatimonadota (2.448 ± 0.447%), Firmicutes (1.193 ± 0.634%), Patescibacteria (0.435 ± 0.813%), and Nitrospirota (0.612 ± 0.468%). Proteobacteria and Actinobacteria were predominant at the phylum level, which showed a certain tolerance to HMs. In addition, redundancy analysis (RDA) results showed that Pb, Cu, Zn, and Cd were strongly correlated with each other (P < 0.01). Other nutrient elements (except for TK) were significantly positively correlated with each other. Cu and nutrient element TK had an important impact on bacterial community structure. Therefore, bacteria with the function of HM tolerance and bioremediation in extreme environments should be researched, which provides a foundation for future ecological remediation of contaminated soil by using microbial remediation technology.
