Technology has an important role in education, namely, facilitating teacher-student interaction in teaching and learning activities. This is realized by applying technology to learning media. The limitation of space building props in learning high school mathematics on the topic of the Third Dimension requires teacher innovation to develop interactive learning media that can be used at any time. The use of Augmented Reality (AR)-based interactive media with Marker-based Tracking techniques is designed to help students visualize 3D objects well. 3D objects were created using the 3Ds Max software. This research produced a product in the form of an AR Distance in Space application that runs on Android. An AR camera is used to detect markers and display cubes, pyramids, and beam objects. The black-box test results show that the application is as planned and can run normally. This means that the AR Distance in Space applications is categorized as Very Good or receives a positive response from users. This application can be used as an interactive learning media that can facilitate students’ understanding of the topic of the Third Dimension and increase student motivation in learning mathematics.

Improving Air Quality Prediction with a Hybrid Bi-LSTM and GAN Model
Authors: Rajakumari R Peter Rupa , Ambadas Lanjewar Ujwal
Published: September 2023

Air quality is a topic that has been of utmost concern across the globe for the past few decades. Various intelligent monitoring systems are used in diverse scenarios, collecting air quality data that contains missing values. Such missing values in data cause hindrances in forecasting. This time series prediction or forecasting process extracts the necessary information from historical records and predicts future values. To solve the missing values issue in data, Generative Adversarial Networks (GAN) are used to impute the missed data. While the learning of long-term dependencies embedded in the time series poses another threat to the models in the time prediction. To overcome this, Long Short-Term Memory (LSTM) models are used. Yet, most of the neural network-based methods failed to consider the patterns of time series data that varied for each period, and the encoder-decoder performance deteriorated for longer sequences. To combat this, the present study proposes a hybrid probabilistic model to generate parameters for predictive distribution at every step. Hence, an implementation of hierarchical-attention-based BiLSTM with GAN is proposed in the study for effective prediction and minimal error. The proposed model is assessed with the evaluation metrics such as Mean Absolute Error (MAE) and Mean Absolute Percentage Error (MAPE), Root Mean Square Error (RMSE), and Mean Square Error (MSE). The evaluation metric confirmed the higher accuracy of the proposed model than the existing models in time series prediction.

Pengaruh Psikologis Hakim Terhadap Ratio Decidendi Dalam Perkara Korupsi
Authors: Sumawan I Putu , Saravistha Deli Bunga
Published: September 2023

Indonesia adalah negara yang termasuk golongan angka korupsi yang tinggi. Dalam upaya penegakan dan pemberantasan korupsi secara regulasi sudah sangat memadai. Dimulai dari komitemn negara pada UNCAC yang telah diratifikasi melalui Undang-Undang Nomor 7 Tahun 2006, menjadi pijakan awal ditetapkannya Undang-Undang Tipikor di Indonesia. Permasalahannya adalah integritas Lembaga Peradilan sebagai the last resort bagi para Justiabellen dalam mencari keadilan, mengalami situasi-situasi yang menempatkan lembaga ini kehilangan public trust. Selain itu, adanya unsur psikologis yang dikatakan dapat mempengaruhi putusan hakim dalam memutus suatu perkara dalam penanganan Tindak Pidana Korupsi dan pengaruhnya bagi integritas Lembaga Peradilan Dan Apakah faktor-faktor di luar hukum tersebut dapat diajukan sebagai landasan pengajuan upaya hukum lanjutan dalam penanganan Tindak Pidana Korupsi. Metode peneltian yang digunakan adalah penelitian hukum normatif dengan menggunakan Teori Sistem Hukum. Hasil penelitian menyatakan bahwa faktor psikologis hakim memberi pengaruh pada ratio decidendi, yang menimbulkan adanya dicenting opinion. Kedua nya sah saja menurut proses penetapan putusan. Namun, faktor psikologis ini juga tidak luput dari intervensi politik yang memiliki energi lebih besar dibaliknya. Perilaku apriori sebagai faktor subjektif dan sikap perilaku emosional, adalah faktor internal yang berpengaruh pada hakim ditambah sikap kekuatan arogansi, yakni perihal kecongkakan akan kekuasaan hakim yang akan cenderung merasa dirinya berkuasa, yang merasa kepintarannya melebihi orang lain (jaksa, pengacara, apalagi terdakwa). Sikap moral hakim itu sebagai manusia pribadi yang berproses tidak jauh berbeda dengan manusia lainnya. Disparitas hakim yang terdistorsi justru berpotensi meningkatkan ketidakpercayaan publik terhadap lembaga ini. Riset ini dilakukan dengan harapan untuk menemukan solusi dalam upaya optimalisasi pemulihan integritas lembaga peradilan dan optimalisasi penegakkan dan pemberantasan korupsi di Indonesia sebagai suatu isu global. Solusi yang dapat ditawarkan dalam rangka membenahi public trust dan wibawa lembaga peradilan adalah memperketat protokol persidangan dan keamanannya, sebagaimana diatur dalam Peraturan Mahkamah Agung (Perma) Nomor 5 Tahun 2020.

Authors: Gorda AAA. Ngurah Sri Rahayu
Published: September 2023

Artikel ini menganalisa dan mengkaji atas kedudukan pihak ketiga pemegang hak tanggungan atas vonis Mahkamah Konstitusi terkait perjanjian pernikahan yang awalnya perjanjian prenuptial menjadi perjanjian postnuptial, khususnya pada pasangan kawin campur. Bank sebagai pemegang hak tanggungan terhadap suatu perjanjian kredit jaminan, selain memiliki dasar prinsip kehati-hatian dalam pemberian kreditnya, diharapkan pula dapat memiliki kepastian hukum dan keadilan dalam kaitannya terhadap perjanjian kredit hak tanggungan yang dibuat sebelum perjanjian perkawinan dibuat oleh pasangan kawin campur. Bank selaku pemberi kredit dalam pembuatan persyaratan kreditnya harus berdasarkan Undang Undang Perbankan dan Peraturan dari Lembaga Pengawas Otoritas Jasa Keuangan (OJK). Bank dalam memberikan kreditnya, juga melihat kredibiltas si calon kreditur. Sehingga pemberian kredit dengan jaminan hak tanggungan dapat diberikan kepada beberapa pasangan perkawinan campur. Berdasarkan penelitian ini perjanjian kredit dengan hak tanggungan maupun perjanjian perkawinan memiliki prinsip dasar dari perjanjian kontraktual, yang berlaku bagi para pihak sehingga memiliki kepastian hukum dan keadilan bagi para pihak. Itikad baik melahirkan keadilan dan kepastian hukum. Tata cara pembuatan dan pendaftaran kedua jenis perjanjian ini selama dilakukan sesuai dengan peraturan perundang-undangan dapat pula melahirkan prestasi dari tiap perjanjian tersebut, akan tetapi dalam prakteknya posisi bank selaku pemberi kredit tidak didukung oleh perundang-undangan yang mengaturnya

Published: September 2023

Data pribadi mencakup setiap informasi yang dapat digunakan untuk mengidentifikasi atau menghubungi individu tertentu, baik informasi tersebut dikumpulkan secara langsung atau tidak langsung melalui metode elektronik dan/atau non-elektronik. UUD 1945 Republik Indonesia menetapkan hak atas privasi sebagai hak dasar warga negara. Tujuan dari penelitian ini adalah untuk mempelajari lebih lanjut tentang perlindungan legislatif Indonesia terhadap data pribadi sebagai hak atas privasi, termasuk sifat dan implementasinya. Melalui pendekatan konseptual, metodologi penelitian yuridis normatif diterapkan. Karena kurangnya undang-undang dan peraturan yang memberikan kerangka hukum untuk perlindungan data pribadi dan menetapkan standar yang mengikat, Indonesia tidak dapat memberikan perlindungan data pribadi tingkat tertinggi kepada warga negaranya. Hasil penelitian menjelaskan bahwa Indonesia belum memiliki peraturan perundang-undangan khusus yang mengatur tentang perlindungan data pribadi, namun sudah memiliki RUU Perlindungan Data Pribadi sebagai sarana pelaksanaan tugas pemerintah untuk melindungi hak konstitusional warga negara Indonesia sebagaimana diatur dalam UUD 1945. UUDNRI, khususnya dalam Pasal 28 huruf G ayat (1). UU PDP memiliki kekurangan, antara lain cara penanganan privasi data anak dan penyandang disabilitas yang diatur secara khusus. Namun, ada kecenderungan semua informasi tentang anak dan penyandang disabilitas disalahgunakan.

Authors: Febrianti Dwi Fitri Annisa
Published: September 2023

Filsafat kebangsaan berfungsi sebagai dasar bagi setiap bangsa.Bangsa dan kehendak rakyat diwujudkan dalam filosofi itu. Dalam sistem hukum Indonesia, Pancasila berfungsi sebagai sumber hukum materil karena mengharuskan setiap peraturan yang bertentangan dengannya segera dicabut jika bertentangan. Dalam Pembukaan UUD 1945, Pancasila disebut sebagai Undang-Undang Dasar Pemerintahan. Hal ini menjadi acuan bagi aparatur pemerintah dalam menjalankan tanggung jawabnya untuk bertindak sesuai dengan aturan hukum yang berlaku, yang juga diperlukan untuk menjaga keberlakuan aturan hukum tersebut. Demikian pula kewajiban pejabat pemerintah untuk melaksanakan tanggung jawabnya dalam parameter pendelegasian wewenang, yang dapat mengakibatkan terbentuknya hubungan hukum antara pemberi dan penerima wewenang. Dalam penelitiannya, Hukum Tata Pemerintahan dipandang dalam konteks tugas pemerintahan dan konsekuensi hukum yang ditimbulkannya. Ini mencakup aspek hukum kehidupan organisasi pemerintah seperti pemerintah negara bagian dalam hal hubungan hukum antara lembaga negara dan berbagai kompetensi hukum kelembagaan pemerintah negara bagian; susunan pemerintahan daerah menurut undang-undang yang mengatur tentang otonomi daerah; dan akibat hukum bagi organisasi pemerintah di desa dan kecamatan. Ini juga berkaitan dengan aspek penyelesaian perselisihan yang ditimbulkan oleh tindakan pemerintah atau antara pemerintah dan warga negara yang dilindunginya.

Background: Cesarean section is a common surgical procedure that may be considered a safe alternative to natural birth and helps to resolve numerous obstetric conditions. Still, the Cesarean section is painful; relieving pain after a Cesarean section is crucial, therefore analgesia is necessary for the postoperative period. However, analgesia is not free of complications and contraindications, so massage may be a cost-effective method for decreasing pain post-Cesarean. Our study aims to determine the massage role in pain intensity after Cesarean sections.
Methods: We searched five electronic databases for relevant studies. Data were extracted from the included studies after screening procedures. We calculated the pooled mean difference (MD) and standardized mean difference (SMD) for our continuous outcomes, using random or fixed-effect meta-analysis according to heterogenicity status. Interventional studies were assessed for methodological quality using the Cochrane risk-of-bias assessment tool, while observational studies were assessed using the National Institutes of Health’s tools.
Results: Our study included 10 RCTs and five observational studies conducted with over 1,595 post-Cesarean women. The pooled MDs for pain intensity considering baseline values either immediately or post 60-90 minutes were favoring the massage group over the control group as follows:(stand. MD = -2.64, 95% CI [-3.80, -1.48], p > .00001; MD = -2.64, 95% CI [-3.80, -1.48], p > .00001, respectively). While pooled MDs regarding post-intervention only either immediately or post 60-90 minutes were:(stand. MD = -2.04, 95% CI [-3.26, -0.82], p = .001; stand. MD = -2.62, 95% CI [-3.52, -1.72], p > .00001, respectively).
Conclusion: Our study found that using massage was superior to the control groups in decreasing pain intensity either when the pain was assessed immediately after or 60-90 minutes post-massage application.

The tip of the red giant branch (TRGB) provides a luminous standard candle for constructing distance ladders to measure the Hubble constant. In practice, its measurements via edge-detection response (EDR) are complicated by the apparent fuzziness of the tip and the multipeak landscape of the EDR. Previously, we optimized an unsupervised algorithm, Comparative Analysis of TRGBs, to minimize the variance among multiple halo fields per host without relying on individualized choices, achieving state-of-the-art ∼<0.05 mag distance measures for optimal data. Here we apply this algorithm to an expanded sample of SN Ia hosts to standardize these to multiple fields in the geometric anchor, NGC 4258. In concert with the Pantheon+ SN Ia sample, this analysis produces a (baseline) result of H
0 = 73.22 ± 2.06 km s−1 Mpc−1. The largest difference in H
0 between this and similar studies employing the TRGB derives from corrections for SN survey differences and local flows used in the most recent SN Ia compilations that were absent in earlier studies. The SN-related differences total ∼2.0 km s−1 Mpc−1. A smaller share, ∼1.4 km s−1 Mpc−1, results from the inhomogeneity of the TRGB calibration across the distance ladder. We employ a grid of 108 variants around the optimal TRGB algorithm and find that the median of the variants is 72.94 ± 1.98 km s−1 Mpc−1 with an additional uncertainty due to algorithm choices of 0.83 km s−1 Mpc−1. None of these TRGB variants result in an H
0 of less than 71.6 km s−1 Mpc−1.

During Encounter 11, Parker Solar Probe observed a low-energy dispersive ions event of solar origin. The event was observed in the SPAN-I and IS⊙IS EPI-Lo sensors. The event started at a few MeV energy in the EPI-Lo sensor and progressed down in energy to ≈1 keV and merged with the bulk of the solar wind. This event is substantially different from typical solar energetic particles because the energetic population shows a distinct peak in the energy spectrum that descends in energy (not a power-law tail). In this Letter, we explore this event’s nature, origin, and characteristics.
Can LISA Resolve Black Hole Binaries in the M87 Globular Clusters?
Authors: Evans Donavon , Kremer Kyle
Published: September 2023

As stellar black holes (BHs) interact with one another in globular clusters, BH binaries form, inspiral, and merge via gravitational wave emission. These dynamically formed BH binaries may account for a fraction of the sources observed by LIGO/Virgo and, earlier in their inspirals, may be detected at millihertz frequencies by LISA in nearby galaxies. M87, known to contain over 104 globular clusters, is a promising candidate for such millihertz sources. Utilizing N-body cluster simulations, we investigate the binary BH population in M87 clusters. Although thousands of sources in LISA’s frequency range (10−5–1 Hz) are expected in M87's clusters, we predict none are resolvable with sufficiently high signal-to-noise ratios. We predict the nearest globular clusters in the Milky Way and clusters found in distant galaxies (d ≳ 100 Mpc) near LISA’s detection horizon for stellar BH binaries are more promising hosts of resolvable LISA sources.
Improved Redshifts for DESI EDR Quasars
Authors: Wu Qiaoya , Shen Yue
Published: September 2023

The Dark Energy Spectroscopic Instrument (DESI) survey will provide optical spectra for ∼3 million quasars. Accurate redshifts for these quasars will facilitate a broad range of science applications. Here we provide improved systemic redshift estimates for the ∼95k quasars included in the DESI Early Data Release (EDR), based on emission-line fits to the quasar spectra. The majority of the DESI pipeline redshifts are reliable. However, ∼19% of the EDR quasars have pipeline redshifts that deviate from our new redshifts by >500 km s−1. We use composite quasar spectra to demonstrate the improvement of our redshift estimates, particularly at z > 1. These new redshifts are available on Zenodo:10.5281/zenodo.8302310

Unravelling bird nest arthropod community structure using metabarcoding
Authors: Levesque-Beaudin Valerie , Steinke Dirk , Böcker Mieke , Thalinger Bettina
Published: September 2023

Bird nests are fascinating microcosms harboring a wide range of arthropods parasitizing the nesting birds or feeding on prey remains, feces, and the nest material. Studies of these communities have been entirely based on emergence traps which collect live organisms out of the nests. The analysis of nest contents and environmental DNA (eDNA) via metabarcoding could expand our knowledge and identify prey, exuviae, and other animal remains in bird nests. Here, we investigated the potential of arthropod remains, nest dust, and feathers to better describe arthropod diversity accumulated in 20 bird nests collected in Guelph (Canada). We used subsampling strategies and tested two extraction approaches to investigate the distribution of DNA in nests, account for low-quality DNA, and the presence of inhibitory substances. In total, 103 taxa were detected via metabarcoding. Arthropod remains delivered the highest number of taxa (n = 67), followed by nest dust (n = 29). Extractions with the PowerSoil kit outperformed DNeasy extractions coupled with PowerClean Pro inhibitor removal. Per nest, on average 5.5% taxonomic overlap between arthropod remains of different size classes was detected and subsamples of nest dust extracted with the PowerSoil kit showed 47.3% taxonomic overlap indicating a heterogeneous eDNA distribution in nests. Most detected species were either feeding in the nest, i.e., herbivorous / predatory, or bird food. We also detected molecular traces of 25 bird species, whose feathers were likely used as nest material. Consequently, the metabarcoding of bird nest materials provides a more complete picture of nest communities, which can enable future studies on functional diversity and better comparisons between nesting species.

Published: September 2023

Since the world is currently in the midst of a major biodiversity crisis, scientists have assigned high conservation priority to 36 biodiversity hotspots around the world. As part of one of the leading hotspots in terms of species richness and local endemism, Vietnam is considered a country with high conservation priority. The reptile fauna of Vietnam is known for its high level of diversity and an outstanding number of endemic species. Vietnamese reptiles are highly threatened due to habitat loss and overharvesting for domestic and international trade, traditional medicine and food, making them a group of great conservation concern. As a baseline for improved reptile conservation in Vietnam, we conducted a conservation assessment of Vietnamese reptile species by evaluating data from a variety of sources. Our study results show that approximately 32.9% (n = 159) of the total reptile species (n = 484) present in Vietnam are endemic to the country, of which more than half are only known from their type locality and about one-third restricted to a particular subregion, making the species particularly vulnerable to threats. Furthermore, 33.5% (n = 53) of 158 endemic taxa included in the protected area analysis have not yet been recorded from any protected area. Among all 418 Vietnamese reptile species listed on the IUCN Red List, 17.7% (n = 74) are threatened with extinction, 46.0% (n = 34) of the total 74 threatened species are endemic to Vietnam. The fact that 135 species are either listed as DD or have not yet been evaluated by the IUCN highlights the urgency of further research. Moreover, only very few species are protected by national or international legislation, and further assessments are needed to protect reptiles of particular concern. A Zoological Information Management System (ZIMS) analysis revealed that 22.5% (n = 109) of all reptiles occurring in Vietnam and only 6.3% (n = 10) of the endemic Vietnamese reptiles are currently kept in zoos worldwide. Although 60.8% (n = 45) of the threatened reptiles (n = 74) from Vietnam are currently held in zoos, only 23.5 (n = 8) of the endemic threatened species (n = 34) are held there. Following the IUCNCPSG`s One Plan Approach to Conservation, it is therefore recommended to increase the number of threatened and endemic species in breeding stations and zoos to maintain assurance populations, suitable for restocking measures. Despite ongoing efforts in Vietnam, further conservation measures are required. We therefore also identify areas of highest reptile diversity and with the largest number of threatened species and provide a list of 50 most threatened species (10% of total species) as a guide for further research and conservation action in Vietnam.

Background: The COVID-19 pandemic affected physicians’ practices of prescribing antibiotics for Upper Respiratory Tract Infections (URTIs).

Aim: This study aims to explore the perceptions of resident physicians in a teaching hospital towards antibiotic prescribing for Upper Respiratory Tract Infections (URTIs) during the COVID-19 pandemic.

Methods: This was a qualitative study based on conducting in-depth face-to-face interviews with resident physicians. Interviews were audio-recorded, transcribed verbatim in Arabic, translated to English, anonymised, and analysed thematically.

Results: Data analysis produced five broad themes: determinants of prescribing antibiotics for URTIs before and after the pandemic, uncertainty in differentiating between COVID-19 cases and other URTIs, the shift in antibiotic prescribing for URTIs following the pandemic, the place of azithromycin in the treatment of COVID-19, and patients’ expectations of antibiotic prescribing.

Conclusion: The study demonstrated that the COVID-19 pandemic added to the complexity of controlling the use of antibiotics in a country that is already striving against inappropriate antibiotics utilization.

Cet article s’intéresse aux carrières féminines en Suisse romande dans le domaine de la protection de l’enfance, dans la seconde moitié du xx e siècle. S’appuyant sur des entretiens biographiques réalisés avec des professionnelles qui ont été actives sur ce terrain (éducatrices sociales, travailleuses sociales, juges des mineur·es, directrices de foyers), nous questionnons leur place dans ce domaine d’intervention et interrogeons la spécificité des parcours féminins en regard de ceux de leurs collègues masculins, en abordant successivement plusieurs thématiques présentes dans leurs témoignages : origine sociale et familiale, formation, postes occupés, réformes rêvées ou accomplies, déroulement de carrière et promotion. Si des points communs avec leurs confrères masculins sont observables, pointant vers une homogénéisation progressive dans le déroulé des carrières à la fin du xx e siècle, l’article évoque quelques-unes des spécificités qui traversent ces parcours féminins au cours de la période considérée : possibilités de promotion grâce aux opportunités offertes par le secteur privé, rôle des réseaux d’interconnaissance féminins dans la construction des carrières, intérêt pour les problématiques des mineures, spécificité du lien personnel et affectif avec les publics.
Multi-features combinatorial optimization for keyframe extraction

Recent advancements in network and multimedia technologies have facilitated the distribution and sharing of digital videos over the Internet. These long videos contain very complex contents. Additionally, it is very challenging to use as few frames as possible to cover the video contents without missing too much information. There are at least two ways to describe these complex videos contents with minimal frames: the keyframes extracted from the video or the video summary. The former lays stress on covering the whole video contents as much as possible. The latter emphasizes covering the video contents of interest. As a consequence, keyframes are widely used in many areas such as video segmentation and object tracking. In this paper, we propose a keyframe extraction method based on multiple features via a novel combinatorial optimization algorithm. The key frame extraction is modeled as a combinatorial optimization problem. A fast dynamic programming algorithm based on a forward non-overlapping transfer matrix in polynomial time and a 0-1 integer linear programming algorithm based on an overlapping matrix is proposed to solve our maximization problem. In order to quantitatively evaluate our approach, a long video dataset named 'Animal world' is self-constructed, and the segmentation evaluation criterions are introduced. A good result is achieved on 'Animal world' dataset and a public available Keyframe-Sydney KFSYD dataset [1].
“Is a game really a reason for people to die?” Sentiment and thematic analysis of Twitter-based discourse on Indonesia soccer stampede

Published: September 2023

This study examined discourses related to an Indonesian soccer stadium stampede on 1st October 2022 using comments posted on Twitter. We conducted a lexicon-based sentiment analysis to identify the sentiments and emotions expressed in tweets and performed structural topic modeling to identify latent themes in the discourse. The majority of tweets (87.8%) expressed negative sentiments, while 8.2% and 4.0% of tweets expressed positive and neutral sentiments, respectively. The most common emotion expressed was fear (29.3%), followed by sadness and anger. Of the 19 themes identified, “Deaths and mortality” was the most prominent (15.1%), followed by “family impact”. The negative stampede discourse was related to public concerns such as “vigil” and “calls for bans and suspension,” while positive discourse focused more on the impact of the stampede. Public health institutions can leverage the volume and rapidity of social media to improve disaster prevention strategies.

Objectives: Prolactin is vital for breastfeeding and milk production, and its secretion is influenced by factors related to the mother, infant, and environment. To date, no study has concurrently investigated the correlation of these factors with serum prolactin levels during lactation. Therefore, the objective of this study was to investigate the correlations among maternal and infant factors, lead exposure, and serum prolactin levels during lactation.Methods: A cross-sectional approach was employed in Surabaya, Indonesia, among 110 exclusively lactating mothers. The mothers’ daily diets were determined using multiple 24-hour recalls, while blood lead levels were measured with inductively coupled plasma mass spectrometry. Serum prolactin levels were assessed using the electrochemiluminescence immunoassay. For bivariate analysis, we employed the Spearman correlation, Mann-Whitney, and Kruskal-Wallis tests, while for multivariate analysis, we utilized multiple linear regression.Results: The average serum prolactin level of the lactating mothers was 129.19±88.96 ng/mL. Positive correlations were found between serum prolactin levels and breastfeeding frequency (p < 0.001), protein intake (p < 0.001), and calcium intake (p = 0.011) but had negative correlation with blood lead levels (p < 0.001) and vitamin B6 intake (p = 0.003). Additionally, prolactin levels were not significantly associated with maternal age; parity; intake of calories, vitamin D, vitamin E, zinc, folic acid, magnesium, or iron; infant age; or infant sex.Conclusions: Breastfeeding frequency had a stronger positive relationship with serum prolactin levels than protein and calcium intake. However, lead exposure was associated with reduced serum prolactin levels during lactation. Consequently, specific interventions from policymakers are necessary to manage breastfeeding in mothers exposed to lead.
E segundo he scripto na briuia… La recepción de la materia bíblica alfonsí en la Galicia bajomedieval
Authors: Pichel Ricardo
Published: September 2023

En este trabajo se presenta un estado de la cuestión actualizado relativo a la materia bíblica procedente de la primera parte de la General Estoria de Alfonso X y traducida en el ámbito sociocultural gallego de mediados del siglo XIV, con el objetivo de incidir en la necesidad de retomar el análisis del estadio redaccional que transmite el principal testimonio de esta tradición textual (RBME Ms. O.I.1), así como de su contexto de producción y recepción, en particular en lo que concierne a la retraducción castellana (RBME Ms. Y.III.12) y a la tradición portuguesa conservada.
Biblias perdidas y fragmentos recuperados
Authors: Avenoza Gemma
Published: September 2023

El número de manuscritos bíblicos hispánicos en lengua vulgar conservados es pequeño en comparación con lo que sucede, por ejemplo, con la tradición francesa. Aunque no imposible, no es muy probable que aparezcan muchos más testimonios íntegros, lo que da un gran valor a los fragmentos de biblias que fueron desmembradas durante los siglos XV-XVI para reutilizar los folios de pergamino como cubiertas o refuerzos de otros libros. En los fondos de Clero y de Inquisición del AHN se han localizado en los últimos años varios bifolios y fragmentos de todo tamaño y condición que dan idea de la calidad y cantidad de manuscritos bíblicos que circularon por la Península en romance. Este trabajo se dedica exclusivamente a presentar los fragmentos castellanos localizados. Algunos proceden de un único manuscrito, incluso del mismo folio y reproducen traducciones conocidas; otros, en cambio, presentan un texto nuevo.
Precisiones sobre las biblias romanceadas castellanas: patronos, artífices e itinerarios
Authors: Rodríguez Porto Rosa M.ª
Published: September 2023

En este artículo se ofrecen nuevas hipótesis sobre el origen de algunas de las biblias romanceadas castellanas a partir del análisis de su iluminación. En este sentido, la evidencia aquí presentada permite ahondar en el estudio de la ilustración bíblica en Castilla a lo largo del siglo XV, así como en el análisis de las particulares dinámicas de producción y consumo en las que se insertan estas obras, poniendo el acento en el limitado círculo nobiliario al que conviene adscribir los más lujosos testimonios conservados. Además, la reconstrucción del contexto social específico al que irían dirigidas algunas de estas biblias sugiere una interpretación alternativa de algunos documentos inquisitoriales, ya publicados, en los que se hace alusión a los antiguos posesores de ciertas biblias escurialenses. A juzgar por la cuidadosa omisión o confusión interesada en cuanto al origen de algunas de ellas, la negociación entre el Santo Oficio y Felipe II para permitir su custodia en la biblioteca regia hubo de ser aún más sutil de lo que se pensaba.
