El nuevo Plan Nacional de Educación Patrimonial, una estrategia imprescindible
Authors: Fontal Merillas Olaia , Maestre Maestre Esther , Rejano Peña David
Published: October 2024

Tras una década de desarrollo y ejecución, el Plan Nacional de Educación Patrimonial (en adelante PNEP) ha sido objeto de una revisión y actualización centrada en cuatro ejes: el concepto de patrimonio, los criterios de actuación, los ámbitos en los que se producen procesos de enseñanza-aprendizaje del patrimonio y las personas. Revisado con aportaciones del Ministerio de Cultura y las diferentes comunidades autónomas, el plan busca fomentar la creación de programas de educación patrimonial como estrategia clave para valorar el patrimonio cultural y garantizar el acceso a la cultura. Varias comunidades ya han implementado con éxito estos planes, destacando Madrid, Galicia y Canarias o, próximamente, Castilla y León. El PNEP prioriza la planificación estratégica, la colaboración entre territorios y la organización de eventos como el Congreso Internacional de Educación Patrimonial. Se espera que el plan impulse nuevos proyectos que promuevan la investigación, la innovación y la apropiación ciudadana del patrimonio cultural. El PNEP se integra en un conjunto de quince Planes Nacionales de Patrimonio Cultural que coordinan la salvaguarda del patrimonio en constante evolución; estos planes, desarrollados con un enfoque multidisciplinar y consensuado, buscan reflejar una sociedad en transformación y legitimar nuevos patrimonios culturales. El PNEP se enfoca en las comunidades y sus vínculos emocionales con el patrimonio, y sirve de referencia para la renovación de otros planes en redacción o reformulación, adaptándose a las demandas de una ciudadanía cada vez más involucrada en la gestión patrimonial.

Sobre la relación de la Universidad con su patrimonio
Authors: Méndez Rodríguez Luis , Bellido Gant María Luisa
Published: October 2024

Las universidades y su patrimonio, material o inmaterial, cultural o natural, constituyen un legado inestimable que conecta a la sociedad actual con el pasado y proporciona un sentido de identidad a la comunidad, visible en sus edificios, colecciones y museos. Se reúnen en este número monográfico de revista PH 113 un conjunto de artículos, experiencias, casos prácticos y reflexiones que analizan el legado histórico, artístico, científico, inmaterial… de las universidades, en un momento de encurcijada, marcado por la redefinición del papel de estas y del propio concepto de patrimonio. Así mismo, se constata que el incremento del interés por los bienes culturales de las instituciones de enseñanza superior no se ve acompañado de un mayor compromiso por parte de las administraciones. En estas circunstancias, hay que indagar en cómo las universidades están cuidando su patrimonio, cómo lo están haciendo y qué tipologías son las que se están atendiendo, además de explorar las redes que, a distintas escalas territoriales, intentan dar respuesta a las amenazas sobre el patrimonio universitario. Esta contribución, firmada por las personas que han asumido la coordinación del número, sintetiza las principales aportaciones.

Published: October 2024

Penyebaran covid-19 sangat berdampak di segala sektor, tak terkecuali sektor pendidikan. Melihat kasus yang terus meningkat, Kementerian Pendidikan dan Kebudayaan Republik Indonesia mengeluarkan surat edaran Nomor 4 tahun 2020 pada tanggal 24 Maret 2020 yang berisi Tentang Pelaksanaan Kebijakan Pendidikan dalam Masa Darurat Dalam Penyebaran Covid-19. Salah satu isi dari surat edaran tersebut adalah mengalihkan metode pembelajaran tatap muka disekolah dengan metode pembelajaran jarak jauh (PJJ) yang dilaksanakan dirumah. Hal yang perlu diperhatikan seorang pendidik saat pembelajaran jarak jauh (PJJ) secara daring adalah minat belajar. Jika siswa memiliki minat belajar yang tinggi maka akan memudahkan siswa tersebut dalam mencapai tujuan belajar, begitupun jika siswa memiliki minat belajar yang rendah maka akan mengakibatkan kurangnya rasa ketertarikan siswa tersebut terhadap suatu bidang tertentu.  Dalam proses pembelajaran jarak jauh (PJJ) secara daring ini, guru SMP Kartikatama Metro banyak menggunakan pendekatan pembelajaran konvensional dengan metode ceramah. Sehingga siswa cenderung pasif karena kurang dilibatkan dalam mencari penyelesaian masalah matematika yang akan berdampak pada rendahnya minat belajar siswa. Oleh karena itu, perlu suatu metode yang tepat untuk diaplikasikan pada pembelajaran matematika yang dilaksanakan secara daring. Salah satu metode tersebut adalah Pendekatan Matematika Realistik. Dari penelitian yang telah dilakukan pada 20 siswa kelas VIII Kartikatama Metro didapat bahwa minat belajar pada metode Pembelajaran Matematika Realistik ≠ minat belajar pada metode pembelajaran konvesional (ceramah). Hal ini diperkuat dengan hasil perhitungan t-test dengan hasil  yakni 11,90 > 2,306.Kata Kunci: Daring, Minat Belajar, Pendekatan Matematika Realistik.

Published: October 2024

Fractions are one of the materials that have an important role in mathematics learning both domestically and abroad. Therefore, several articles discussing fractions published in several journals can be found in several sources, both national and international. This article aims to provide an overview of learning fractions, especially in context, activities and learning outcomes based on relevant literature. Therefore, we are interested in conducting a Systematic Literature Review (SLR) of the 10 articles resulting from the Meta analysis (PRISMA) process. This research focuses on three aspects, namely: 1) Activities and contexts used in learning fraction material, 2) Learning outcomes related to the application of these activities and contexts and 3) Main findings in the research. Systematic literature review found that there were 10 contexts and activities implemented in learning fraction material. Apart from that, we also concluded that the holistic, interactive and contextual learning approach, namely PMRI, had a positive impact on students' understanding of fraction material. Providing meaningful and relevant experiences can increase student interest and build a strong foundation for further mathematical understanding. The results of this research can provide a summary of existing literature and literature to identify weaknesses or gaps for further investigation in future research related to the topic of fractions.

Introduction: This study aims to evaluate the persistence, treatment adherence and drug cost associated with biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs) in the management of psoriatic arthritis (PsA) in Italy, with a focus on biosimilar drugs.
Methods: This was a retrospective observational study involving eight hospital pharmacies, between January 2017 and December 2020, on naïve patients with at least one b/tsDMARD dispensation indicated for PsA. Patients were followed up for 12 months and persistence and adherence were evaluated by proportion of days covered (PDC). The originator and biosimilar for adalimumab and etanercept were compared. Furthermore, the real annual cost per patient based on adherence to therapy was calculated.
Results: Patients initiating b/tsDMARDs for PsA had a mean persistence of 263 days and 48.6% remained persistent for 1 year. Adherent patients (PDC ≥ 0.8) were 47.6% for the overall population. Similar persistence and adherence were observed between patients treated with the adalimumab originator and its biosimilar, while patients treated with the etanercept originator showed lower persistence and adherence compared to those treated with its biosimilar (mean persistence: 222 vs. 267 days, patient persistent at 1 year: 29.4% vs. 51.5%, mean PDC: 0.53 vs. 0.70, adherent patients: 23.5% vs. 51.5%). The average annual drug cost ranged from €8,724 (etanercept) to €14,783 (ustekinumab), with an annual saving of more than €2,500 by using biosimilars.
Conclusion: Poor adherence to medications contributes to suboptimal clinical outcomes. The comparison between biosimilar and originator offers further evidence in support of the biosimilar to optimizing resources in healthcare.
Nearshore fish abundance in an urban estuary is weakly associated with shoreline conditions across spatial scales
Authors: Bishop EE , Essington TE , Samhouri JF , Feist BE , Sullaway GH , Toft JD , Francis TB
Published: October 2024

Understanding the scale at which species respond to habitat characteristics can improve detection of effects from anthropogenic alterations to marine shorelines. Spatial context matters because habitat alteration may have more of an effect when prevalent throughout a region, depending on the spatial scale at which species experience changes in habitat value. In this study, we examined the associations of 4 highly motile fish species with shorelines that are altered via shoreline armor. We sampled fish for 4 yr in the Salish Sea, Washington, USA, and used model selection to evaluate the weight of evidence for associations between fish abundance and shoreline armor extent within hierarchically nested spatial scales. We evaluated species that inhabit nearshore waters under different contexts during their life histories because we expected different associations with armor between them. Of the species that are beach-associated at multiple times during their life histories, surf smelt showed no association with armor while Pacific herring showed a negative association, particularly at larger spatial scales. Of the species that pass through nearshore habitats during outmigration to the ocean, juvenile Chinook and chum salmon both showed slightly positive associations with armor presence, but these associations were not strong. The stronger association we observed in herring suggests that they may avoid areas with greater armor presence throughout a region. Distributions of anadromous species during migration are likely governed by other factors. This work highlights the importance of maintaining ecological context when considering future research aimed at understanding the impacts of shoreline armor on fish populations.
FROM TERRITORIAL RESILIENCE TO INDUSTRIAL MOTRICITY AS AN ECONOMIC MODEL FOR THE AFRICAN CONTRYSIDE GROWTH
Authors:   University of Kikwit, Democratic Republic of Congo, Musema Zombo Morris
Published: October 2024

This article deals with a case study relating to the capacity for resilience, developed by the indigenous communities of the region of Simba in the territory of Bulungu in the Kwilu, located in the abandoned oil areas formerly exploited by Unilever in Congo. To better support the local growth of villages and promote the efforts of such a multidimensional territorial resilience in developing countries, the study proposes industrial motricity as an economic model likely to strategically play the role of a real tool in the fight against poverty. In view of the local resources available, the study makes some practical proposals on how water, coupled with soft energy, small rural industry and human capital, could suggest not only a few landmarks built on a square symbiotic, but also, provide relevant responses to the socio-economic development problems faced by local communities, thanks to the transformation of local resources from available into finished products with high added value, creating wealth, thus offering employment proximity to young people, and supporting local growth.
A pilot study of cardiac guided wave elastography: an ex vivo testing in a rodent model with mechanical testing validation
Authors: Liu Jingfei , Corporan Daniella , Vanderlaan Don , Padala Muralidhar , Emelianov Stanislav Y.
Published: October 2024

Many heart diseases can change the elasticity of myocardial tissues, making elastography a potential medical imaging strategy for heart disease diagnosis and cardiovascular risk assessment. Among the existing elastography methods, ultrasound elastography is an appealing choice because of ultrasound’s inherent advantages of low cost, high safety, wide availability, and deep penetration. The existing investigations of cardiac ultrasound elastography were implemented based on a bulk model of heart tissue, treating the waves generated in the myocardial tissues as shear waves. In this pilot study, we considered the distinct geometric characteristics of heart tissue, i.e., being a layered structure and its dispersive nature as biological tissue. Based on these considerations, we modeled heart tissues as a layered-dispersive structure and developed a new ultrasound elastography method, ultrasonic guided wave elastography, to characterize the myocardial elasticity. The validity of this layered-dispersive model and the reliability of the developed guided wave elastography were first verified on tissue-mimicking phantoms. Then, the guided wave elastography was applied to an ex vivo imaging of a rat heart tissue specimen in real-time during the biaxial planar mechanical testing. The comparison of the real-time myocardial elasticity obtained from guided wave elastography and mechanical testing demonstrated strong matching, verifying the reliability of the developed cardiac guided wave elastography as a potential method for characterizing myocardial elasticity.
How do we feed our livestock? Knowledge, perceptions and informational needs of the public and farmers in Germany
Authors: Hoffmann Martina , Zupaniec Milena , Lohmann Mark , Böl Gaby-Fleur , Pieper Robert , Mader Anneluise
Published: October 2024

Little is known about knowledge and perceptions of the public and farmers on livestock feed. However, it is important to know their perspectives to find widely accepted and sustainable solutions in agriculture, which account for animal welfare, societal expectations, economy and the environment alike. Therefore, the objective of the present study was to assess knowledge, perceptions and informational needs regarding livestock feed among the general population and farmers. A German-wide online survey was conducted with n = 1000 participants from the general population (representative for age and gender) and n = 251 farmers. Differences in answers were compared between the general population and farmers as well as between subgroups of the general population. Results indicate that the public is correctly informed about some livestock feeds, although knowledge gaps and misconceptions became evident. The general population rated potatoes, fodder beets, kitchen waste and bread as common feedstuffs for pigs, which was rather a common practice in smallholder “backyard” pig husbandry several decades ago. Ratings of relevant aspects of feed differ between the two groups and partially depend on sociodemographic variables (i.e. gender, rural/urban upbringing, age) in the general population. Farmers were more likely to have heard and know the meaning of the term feed additives and are better informed about the functions that are fulfilled by feed additives. Farmers also expressed higher agreement for use of most alternative feeds than participants from the general population, although no differences of acceptance levels were found for algae, insects, animal by-products and fungi. In the group of the general population, 56% agree with the use of cereals and only 17% with the use of soy as livestock feed. When asked for the level of knowledge on livestock feed, 42% of participants from the general population indicate low or very low knowledge, whereas 97% of farmers judged the knowledge among the public to be low or very low. Both groups rate the need for information on controls of feed highest. Providing more information on livestock feed to the public seems necessary to improve knowledge, increase acceptance of alternative feeds and of sustainable solutions in agriculture.

Introduction

Emerging evidence suggests that the vaginal microbiota is closely associated with cervical cancer. However, little is known about the relationships among the vaginal microbiota, vaginal metabolites, and cervical lesion progression in women undergoing cervical dysplasia.

Methods

In this study, to understand vaginal microbiota signatures and vaginal metabolite changes in women with cervical lesions of different grades and cancer, individuals with normal or cervical dysplasia were recruited and divided into healthy controls (HC) group, low-grade squamous intraepithelial lesions (LSIL) group, high-grade squamous intraepithelial lesions (HSIL) group, and cervical cancer (CC) group. Vaginal secretion samples were collected for 16S rRNA gene sequencing, liquid chromatography coupled with mass spectrometry (LC–MS)-based metabolomics, and integrated analysis.

Results

The results demonstrated that bacterial richness and diversity were greater in the CC group than the other three groups. Additionally, Lactobacillus was found to be negatively associated with bacterial diversity and bacterial metabolic functions, which increased with the degree of cervical lesions and cancer. Metabolomic analysis revealed that distinct metabolites were enriched in these metabolite pathways, including tryptophan metabolism, retinol metabolism, glutathione metabolism, alanine, aspartate, and glutamate metabolism, as well as citrate cycle (TCA cycle). Correlation analysis revealed positive associations between CC group-decreased Lactobacillus abundance and CC group-decreased metabolites. Lactobacillus iners was both negative to nadB and kynU genes, the predicted abundance of which was significantly higher in the CC group. The linear regression model showed that the combination of the vaginal microbiota and vaginal metabolites has good diagnostic performance for cervical cancer.

Discussion

Our results indicated a clear difference in the vaginal microbiota and vaginal metabolites of women with cervical dysplasia. Specifically altered bacteria and metabolites were closely associated with the degree of cervical lesions and cancer, indicating the potential of the vaginal microbiota and vaginal metabolites as modifiable factors and therapeutic targets for preventing cervical cancer.

Although the importance of the microbiome in the context of tick biology and vector competence has recently come into a broader research focus, the field is still in its infancy and the complex ecological interactions between the tick residential bacteria and pathogens are obscure. Here, we show that an environmentally acquired gut bacterium has the potential to impair Borrelia afzelii colonization within the tick vector through a secreted metalloprotease. Oral introduction of either Bacillus cereus LTG-1 isolate or its purified enhancin (BcEnhancin) protein significantly reduces B. afzelii burden in the guts of Ixodes ricinus ticks. This effect is attributed to the ability of BcEnhancin to degrade a glycan-rich peritrophic matrix (PM), which is a gut protective barrier essential for Borrelia survival. Our study highlights the importance of the gut microbiome in determining tick vector competence and provides a deeper mechanistic insight into the complex network of interactions between Borrelia, the tick, and the tick microbiome.
Internal crisis communication: exploring antecedents and consequences from a managerial viewpoint

Over the past decade, internal crisis communication (ICC) has experienced significant advancements and transformations due to various factors, including technological developments, changing communication landscapes, and the increasing need for effective crisis management within organizations. Crises have impacted organizations differently worldwide, placing management under tremendous pressure to communicate their decisions to employees and provide encouraging messages amidst the uncertainty. Based on prior theoretical and empirical research, this paper explores the cause-and-effect relationships between the antecedents of internal crisis communication and their consequences from a managerial perspective in the workplace. This research proposes a new conceptual framework that integrates multiple key factors in internal crisis communication, offering a comprehensive approach to studying the interplay between antecedents and consequences. The framework specifically examines how three antecedents—safety culture, work engagement, and leadership effectiveness—influence and interact with two consequences: perceived organizational performance and employee commitment. By synthesizing these diverse elements into a cohesive model, this framework contributes to the literature on internal crisis communication in several ways. First, it enables the examination of both direct and indirect relationships between antecedents and consequences, potentially revealing new insights into the complexities of crisis communication dynamics. Second, it provides a structured approach for future empirical studies to test and validate these relationships in various organizational contexts. Lastly, it offers a research agenda to advance the study of internal crisis communication, aiding both academics and practicing managers in developing strategies to mitigate uncertainty during crises.
A Mendelian randomization study on the association between systemic inflammatory regulators and essential and secondary hypertension

Background

Inflammation is an important driver of hypertension with numerous components, and there is a paucity of research on the specific inflammatory factors that induce hypertension; therefore, we wanted to investigate the relationship between specific inflammatory factors and hypertension.

Purpose

A two-sample Mendelian randomization (MR) study was conducted to assess the causal relationship between systemic inflammatory regulators and hypertension (primary or secondary types).

Method

a large-scale, published genome-wide association study (GWAS) meta-analysis encompassing 41 cytokines (involved 8,293 Finnish participants from three independent population cohorts: the Cardiovascular Risk in Young Finns Study (YFS), FINRISK1997, and FINRISK2002.)were utilized, a variety of analyses including MR-Egger, weighted median, simple mode and weighted mode were used as sensitive analyses, to corroborate the causal relationship between inflammatory regulators and hypertension. Additionally, we used MR-Egger intercept test and Mendelian Randomization Pleiotropy RE Sidual Sum and Outlier (MR-PRESSO global test) to further evaluate the presence of horizontal pleiotropy.

Results

3 inflammatory regulators were found related to secondary hypertension, TNFb was negatively associated with risk of secondary hypertension, with a OR of one SD increase in genetically predicted TNFb causing 16.6% (95% CI: 4.4%–27.1%) lower risk of secondary hypertension. Similar trend was also found in MIP1b (OR = 0.91; 95% CI 0.84–0.99, p = 0.024) and MIG (OR = 0.88; 95% CI 0.78–0.99, p = 0.040). Additionally, there was not any evidence of 41 inflammatory regulators associated with primary hypertension.

Conclusion

This study supports a negative correlation between TNFb, MIP1b, MIG and secondary hypertension.

In the 2023 hurricane season, the Hurricane Analysis and Forecast System (HAFS) based Ensemble Prediction System (EPS) was being ported to the Amazon Web Service cloud. This relocation aimed to provide real-time hurricane probabilistic forecast guidance for National Hurricane Center (NHC) forecasters. The system comprises Stochastically Perturbed Physics Tendencies (SPPT), Stochastically Kinetic Energy Backscatter (SKEB), and Stochastically Perturbed PBL Humidity (SHUM). Initial and boundary conditions are derived from the National Centers for Environmental Prediction (NCEP) operational Global Ensemble Forecast System (GEFS) 21-member forecast data. The performance of HAFS-EPS for 2023 Atlantic hurricane forecasts was compared with the global GEFS, global ECMWF ensemble, and operational HAFS-A/B forecasts. This comparison highlighted the advantages of higher-resolution regional ensemble forecasts for hurricane track, intensity, Rapid Intensification (RI) probability, and various hazards, including wind, wave, and storm surge probability guidance.
