“I want one nurse who is friendly to talk to me properly like a friend”: Learner preferences for HIV and contraceptive service provision in Gauteng, South Africa
Authors: Moolla Aneesa , Constance Mongwenyana , Ngcobo Nkosinathi , Mngadi Sithabile , Govathson Caroline , Long Lawrence , Pascoe Sophie Jane
Published: December 2023

Background
Research with adolescents indicates that youth aged 15–24 years, especially females, are at high risk for HIV infection. The overall HIV prevalence among youth in this age group was 6.2% estimated in 2022. In addition, > 800,000 adolescents are newly infected with HIV every year and 79% of these infections occur in sub-Saharan Africa. The health service provision preferences and needs of adolescents are critical to reaching this population.
Methods
This qualitative study was conducted with learners from three public secondary schools in Gauteng, South Africa. Using convenience sampling, 22 in-depth stakeholder interviews (KIIs) with stakeholders and 8 focus group discussions (FGDs) with 55 learners aged ≥ 15, were conducted between March and October 2018. Learners < 18 were given assent and parental consent forms, whilst those ≥ 18 could consent of their own accord. KIIs and FGDs were conducted in private venues in the preferred language by trained interviewers and audio-recorded. Audio files were transcribed verbatim and translated into English if needed. Data were analysed thematically using NVivo version 11.
Results
The findings from both stakeholders and learners indicate many critical accessibility barriers which include: negative healthcare staff attitudes from older judgemental staff; stigmatisation from healthcare workers, the community as well as family; a lack of private consulting spaces and no confidentiality of patient information at facilities; inconvenient clinic operating times; long queues and facility resource issues. Both groups of participants suggested that accessibility to healthcare could be improved through value-added services (including free Wi-Fi and food), social gatherings and educational information sessions, as well as being staffed by younger, friendlier, confidential and non-judgemental staff in a private healthcare setting.
Conclusion
It is clear that there are many critical barriers that deter learners from accessing HIV and contraceptive services. Provision of private rooms and trying to ensure information confidentiality for youth-friendly services at locations and times that can be easily accessed by learners is key. Greater emphasis on learner-parent-teacher communication around sexual health education at school is needed along with making this information being more readily available to learners.
Delving potentials of direct and indirect selection parameters in segregating generation differing for stem growth habit in chickpea
Authors: Ambika Ambika , Kumar Rajendra
Published: December 2023

Chickpea (Cicer arietinum L.) is predominantly an indeterminate (IDT) plant and tends to generate vegetative growth when the soil is conducive for soil moisture, temperature, and certain other environmental conditions. The semi-determinate (SDT) types are comparatively early, resistant to lodging and found to be similar in their yield potential to IDT lines. Thus, knowledge on genetic variations for pod and seed traits of different stem growth habit is important. The present study aims to estimate genetic variability and relation between yield and its related attributes of segregating population of chickpea. Variability studies were studied in BGD 362 (IDT) x BG 3078-1(SDT) cross differing for stem growth habit. Wide range of variation was reported for the trait plant height, pods per plant, seeds per plant, seed yield and 100-seed weight. Pods per plant showed high PCV and GCV. Pods per plant, seeds per pod, seed yield, and 100 – seed weight recorded high heritability coupled with high genetic advance. Seed yield per plant has shown highly significant positive association with seeds per plant, pods per plant, and 100 – seed weight. The pods per plant had high positive indirect effect on seed yield per plant indicating that selection for plant types with a greater number of pods per plant will be effective in the simultaneous improvement of seeds per plant and sustainable grain yield in chickpea.

Authors: Ma Guoping , Ma Kexin , Li Mian , Liang Ruijing , Guo Zijing , Xiao Yupeng , Liu Gang , Liang Wenjie
Published: December 2023

Background
Ventricular arrhythmia (VA) is a common clinical disease that is associated with high morbidity and mortality. Calcium/calmodulin-dependent protein kinase II (CaMKII) is critical in regulating cardiac electrophysiological functions. Research shows that propranolol can significantly antagonizes VA. However, it is unclear whether propranolol can regulate CaMKII, thereby inhibiting VA.
Aims
The present study aimed to clarify the molecular mechanism by which propranolol inhibits VA through the CaMKII pathway.
Methods
A total of 60 healthy Sprague Dawley rats were randomly divided into the control and experimental groups (model and propranolol group) that were given corresponding treatment. Isoproterenol hydrochloride (ISO) was administered to induce VA. The ECG was monitored for 1 hour, and the VA incidence was calculated. The heart weight/body weight (HW/BW) ratio was calculated manually. The levels of Ca2+, cTnI, oxidative stress, Inflammatory factors were studied.Calcium pump (SERCA2) and CaMKIIδ mRNA were detected by Real-time PCR. Western blotting was used to assess CaMKII, oxidized CaMKII (OX-CaMKII), phosphorylated phosphoprotein (P-PLB) and SERCA2.
Results
There was no obvious abnormality in the control group. Compared with the control group rats, the indexes of rats in model group changed significantly (P < 0.01). Compared with the model group rats, the indexes of rats in the propranolol was significantly improved (P < 0.01 or P < 0.05 ).
Conclusions
Collectively, propranolol antagonized VA effect by reducing CaMKII expression and activating SERCA2, thereby reducing the Ca2 + load .
Quantum homomorphic aggregate signature based on quantum Fourier transform
Authors: Chen Teng , Lu Dian-Jun , Deng Zhi-Ming , Yao Wei-Xin
Published: December 2023

With the rapid development of computer and internet technology, quantum signature plays an extremely important role in modern secure communication. Quantum homomorphic aggregate signature, as an important guarantee of quantum signature, plays a significant role in reducing storage, communication, and computing costs. This article draws on the idea of quantum multi-party summation and proposes a quantum homomorphic aggregate signature scheme based on quantum Fourier transform. Our scheme uses $n$-particle entangled states as quantum channels, with different particles of each entangled state sent separately. This ensures secure transmission of signatures and messages with fewer entangled particles during transmission, further improving the efficiency of quantum signatures. Meanwhile, our scheme generates private keys for each participating party by randomly constructing key generation matrixes. Different signers perform quantum Fourier transforms and basis exchange operations on entangled particles based on different messages and private keys to generate signatures. In addition, the aggregator does not need to measure and verify the signature particles after receiving signatures from different signers, and the group addition operation process has additive homomorphism. Security analysis shows that our scheme has unforgeability, non-repudiation, and can resist various attacks such as entanglement measurement attacks, intercept-resend attacks, private key sequence attacks, and internal attacks by aggregator.

Authors: Aounallah Houcine , Moussa Abbad , Ahmed Faizuddin , Rudra Prabir
Published: December 2023

In this study, we study the relativistic quantum dynamics, specifically focusing on a spin-0 system described by the Duffin-Kemmer-Petiau (DKP) equation within the context of an Ellis–Bronnikov-type wormhole endowed with topological charge. Our objective is to find the solution to the DKP equation, which, notably, takes the form of the Heun differential equation. Through this investigation, we ascertain the ground energy levels associated to this system. Furthermore, we extend our exploration to the DKP oscillator and employ a similar methodology to derive the ground state energy levels of the oscillator field. In addition, we introduce an electromagnetic four-vector potential and study the DKP oscillator in the wormhole background. An intriguing aspect of our findings lies in the influence of the wormhole's non-trivial topology as well as external potential on the energy levels of this relativistic quantum system.

Published: December 2023

Background In patients with heart failure and a reduced ejection fraction, the overall mortality and morbidity benefit is greatest when treated with the combination of sacubitril/valsartan, beta-blockers, mineralocorticoid-receptor antagonists, and sodium-glucose transporter-2 inhibitors, the so-called "fantastic four" or "quadruple therapy.” Adding vericiguat (an oral soluble guanylate cyclase stimulator) is thought to aid in the management of worsening heart failure after quadruple therapy. Among children and young adult cancer survivors, cardiovascular complications that develop more than ten years after anthracycline-based chemotherapy have a poor prognosis. The efficacy of multidrug therapy based on quadruple therapy for worsening heart failure among cancer survivors with anthracycline-induced cardiomyopathy has not been reported.Case Presentation A young adult cancer survivor who had undergone high-dose anthracycline chemotherapy experienced acute decompensated heart failure 20 years post-chemotherapy and developed worsening heart failure one and a half years after discharge. Initiation of quadruple therapy with necessitous ivabradine induction for the worsening heart failure demonstrated a trend toward improvement. Vericiguat was accelerated because of the risk of more severe cardiovascular events associated with ongoing aortic stenosis and the poor prognosis of anthracycline-induced cardiomyopathy. Heart failure symptoms continued to improve with significant cardiac reverse remodeling, and the patient successfully underwent aortic valve replacement for severe aortic stenosis.Conclusions Multidrug therapy with add-on vericiguat and ivabradine based on quadruple therapy may successfully treat worsening heart failure among high-risk cancer survivors with severe anthracycline-induced cardiomyopathy.

Published: December 2023

Ransomware has rapidly evolved into sophisticated, stealthy threats built to extort payments through data encryption and extraction. This paper presents an innovative methodology for ransomware risk evaluation using the mathematical frameworks of Markov Decision Processes (MDP). By modeling ransomware scenarios as MDPs, overlaying risk equations, and applying our analysis, a quantitative assessment of dynamic risk levels and effectiveness of defensive strategies is enabled. The technique is demonstrated through comparative assessment of prominent ransomware groups, industry-specific impact analysis, and time projections of data theft risk trajectories. Despite limitations in model complexity and real-world validation, the methodology elucidates an interdisciplinary approach blending decision theory, control systems and applied mathematics to enrich cyber risk research.

Stem cells in the plant meristems are kept undifferentiated by signals from surrounding cells and provide the basis for continuous organ formation. In the stem cell organizer of the Arabidopsis thaliana root, the Quiescent Center (QC), the WOX5 transcription factor functions as a central hub in regulating columella stem cell (CSC) homeostasis. However, the processes mediating WOX5 function have yet to be discovered. Here, we identify the transcription factor HAN as a central mediator of WOX5-regulated stem cell maintenance. HAN is required and sufficient to maintain CSCs undifferentiated and to induce ectopic stem cells. WOX5 and HAN repress transcription of the differentiation factor gene CDF4 in a coherent Feed Forward Loop (cFFL), one output of which is the expression of the auxin biosynthesis gene TAA1 and maintaining auxin response maxima in the organizer. Mathematical WOX5/HAN/CDF4cFFL modeling suggests a mechanism to buffer columella stem cell maintenance against input noise.

Published: December 2023

Field-controlled micro-manipulation represents a pivotal technique in handling microparticles, yet conventional methods often risk physical damage to the targets. Here, we have discovered a completely new mechanism for truly non-contact manipulation through photothermal effect, called thermal-optical tweezers. we employing a laser-engraved photothermal waveguide for dynamic microparticle manipulation. This waveguide demonstrates superior photothermal conversion and precision control, generating a non-isothermal temperature field. The interaction of thermal convection and thermophoresis within this field creates a microfluidic potential well, enabling non-contact and non-destructive particle manipulation. By varying the path of photothermal waveguides in lithography and the manipulating laser loading modes, diverse manipulation strategies, such as Z-shaped migration, periodic oscillation, and directional transport, are achievable. Our innovative non-invasive micro-manipulation technology not only minimizes physical damage to target objects but also enables precise and diverse manipulation of micro-entities, opening up new avenues in photothermal control of cells and biomolecules.

Published: December 2023

Background: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a global pandemic that has affected millions of people worldwide. This study aims to bridge the knowledge gap between acute and chronic symptoms, vaccination impact, and associated factors in patients across different low-income countries.

Methods: The study included 2,445 participants aged 18 years and older, testing positive for COVID-19. Data collection involved screening for medical histories, testing records, symptomatology, and persistent symptoms. Validated instruments, including the DePaul Symptom Questionnaire (DSQ-2) and Patient Health Questionnaire-9 (PHQ-9), were used. We applied a self-supervised and unsupervised deep neural network to extract features from the questionnaire. Gradient boosted machines (GMB) model was used to build a risk calculator for chronic fatigue, depression, and prolonged COVID-19 symptoms. The best-performing models were implemented in a shiny app and deployed online at: [https//ahmedshaheen.shinyapps.io/shaheen-covid-19/]. Also, there is an offline version of the application that can be downloaded: [link].

Findings: Out of the study cohort, 69.5% of the patients had symptoms lasting longer than 2 weeks. The most frequent symptoms were loss of smell 46.8%, dry cough (40.1%), loss of taste (37.8%), headaches (37.2%), and sore throat (28.9%). The patients also reported high rates of depression (47.7%), chronic fatigue (6.5%), and infection after vaccination (24.2%). Factors associated with chronic fatigue syndrome included sex, age, and smoking. Vaccinated individuals demonstrated lower odds of experiencing prolonged COVID-19 symptoms, chronic fatigue syndrome, and depression. The predictive models achieved a high area under the receiver operating characteristic curve (AUC) scores of 0.87, 0.82, and 0.74, respectively.

Interpretation: The results provide insights into the consequences of COVID-19 and a predictive tool to understand factors influencing depression, chronic fatigue syndrome, and prolonged COVID-19 symptoms. The study reveals variables affecting these outcomes and the interplay between pre-existing conditions, treatments, and the duration of symptoms post-recovery.
Work hardening in colloidal crystals
Authors: Kim Seongsoo , Svetlizky Ilya , Weitz David A. , Spaepen Frans
Published: December 2023

Colloidal crystals are fascinating materials1-4. They exhibit a rich behavior that is in many ways analogous to their atomic counterparts: they have the same crystal structures2,5-7; they undergo the same phase transitions8-10; and they possess the same crystallographic defects11-15. In contrast to these structural properties, the mechanical properties of colloidal crystals are quite distinct from those of atomic systems. For example, unlike in atomic systems, the elasticity of hard-sphere colloidal crystals is purely entropic16; as a result, they are so soft that they can be melted just by stirring17-19. In addition, crystalline materials deform plastically when subjected to increasing shear and actually become stronger due to the ubiquitous process of work hardening20, which has not been observed in colloidal crystals. Here we show that hard-sphere colloidal crystals do exhibit work hardening; moreover, despite their softness, the shear strength of colloidal crystals can increase and approach the theoretical limit for crystals, a value reached in very few other materials. We use confocal microscopy to show that the strength of colloidal crystals scales as the square root of dislocation density, in good agreement with the classic Taylor prediction21. We find that, surprisingly, Taylor hardening arises through the formation of dislocation junctions, in direct analogy to atomic systems, even though hard-sphere interactions lack the complexity of atomic interactions22,23. The Taylor hardening regime, however, is established only after a transient phase, and it ceases when the crystals become so hard that the strain is localized within a thin boundary layer where slip results from unconventional motion of dislocations. The striking resemblance between colloidal and atomic crystals, despite the many orders of magnitude difference in particle size and shear modulus, demonstrates the universality of work hardening.

Quantum precision measurement using perfect W state via two-body interacting operation
Authors: Li Yan , Ren Zhihong
Published: December 2023

We comprehensively study the metrological performance of perfect W (PW) state in quantum phase measurement, including local operation and two-body interacting operation as the phase generator. The analytical precision limits are obtained in both cases and the decoherence effects are also investigated. The results show that under local operation the precision limit is slightly lower than it from W state, indicating the weaker sensitivity.
Specially, with increasing m the precision limit from the general 3-qubit PW state approaches 1/Sqrt{5}. In the amplitude damping channel, the precision limit decreases first and then increases to the shot noise limit, whereas it is always decreased in phase damping channel. Alternatively, we have also provided the optimal strategies for quantum phase estimation. In the two-body interacting operations, Ising model and Lipkin-Meshkov-Glick (LMG) model are employed to explore the precision limit with respect to interacting strength. It behaves similar in
both cases that with increasing the precision limit surpasses the general Heisenberg limit and gradually converges with W state. However, the difference is also evident that the more qubits involved for achieving Heisenberg limit, the larger the needed \gamma in Ising model but smaller in LMG model. Interestingly, in amplitude damping channel, with increasing an expanding platform area of precision limit emerges in the few-qubit PW state (N < 6), while it gradually disappears in the large qubit case. This will be beneficial to the stable and tunable high-precision measurement, especially under the noisy circumstances.

Michelle Zauner’s Crying in H Mart is an evocative memoir of an Asian- American woman who struggled to accept her mixed heritage. A major turning point in her life was having to deal with grief over the loss of a loved one through the help of food. While food has frequently been studied in relation to grief and identity, the ways in which these intersect is less common and warrants further exploration. Given the multiplicity of identities embodied by the protagonist and their often-conflicting nature, the researchers employed Herman’s dialogical self theory (DST) as a framework to better understand her journey towards self-discovery and acceptance. With each identity being given a voice of their own, the constant negotiation among them became apparent and the role played by food in the process was also highlighted. Findings indicate that food as a primary marker for Michelle to reclaim her own heritage and identity was emphasised repeatedly in the memoir. It reinforces the notion that food is affective in nature because it is capable of evoking emotions and memories that could (re)shape one’s identity. While Michelle initially rejected her Korean (Asian) heritage, she begins to reclaim and embrace it while reconnecting with her ailing mother through their shared affection for Korean food. It is through her love of Korean food that Michelle is able to gradually embrace one of the major changes in her life and subsequently overcome the identity crisis that has been troubling her.
Délices et négation : une approche de l’écriture féminine à travers quelques romans Africains Francophones
Authors:   , Anjugu Taimako Ajigo
Published: December 2023

From the onset, it is worthy to note that, nowadays, just as after the independence of most African countries, several writers from the African continent have been preoccupied with the fate of women. This is because, the African continent was since ancient times characterized by certain traditions and cultures which mainly have contributed to the plight of the women. This goes to emphasise that women in most cases are the victims of misdeeds such as early marriage, forced marriage, prejudices, violence, marginalisation, exploitation, discrimination; in short, vices that lead to devalorisation of African women in Africa. Over time, some contemporary French-speaking African writers have responded to the devaluation and valuation of women in their novels using 21st century objective view. With regard to the theme that we decided to address in this research, it is worth knowing that the preponderant task is based on the socio-critical theory, postulated by Claude Duchet. Meanwhile, recourse is also made to the comparative method by Rens, Bod et al. However, since the author’s message could be understood by the reader through the use of some expressions or terms that speak directly to the themes of the research, and that a reader’s role in reading experience cannot be overemphasised, we have been able to also lean on the Reader-response theory of Louise Michelle Rosenblatt. The three methods were used concurrently especially that the analysis of each text is based on how characters are being depicted leading us to realizing that our findings on how the African woman is devalued in the first part of the research, while in the second part of the thesis, our findings demonstrate that a lot of tributes are showered on the African woman due to her numerous outstanding qualities. In effect, our findings also reinforce a significant shift in the narrative that concerns the contemporary view on womanhood. Hence, moving from a dogmatic overconcentration on her lot to the new era woman whose lot is now redefined via the new wave feminist perspective on the negation of the African woman. This could be said to be in line with Amadiume Ifi’s contributions and pioneering work in feminist discourse towards new ways of thinking about sex and gender, the question of power, and women’s place in history and culture.
An application of creative problem-solving approach in forming public management competencies
Authors: Giedraitytė Vidmantė , Smaliukienė Rasa
Published: December 2023

Modern bureaucratic competencies, such as creativity, innovative problem-solving, and critical thinking, have become essential in contemporary public management due to complex challenges in a wide range of areas, including the economy, social welfare, and the environment. This has led to a greater focus on developing these competencies, through innovative methods like creative problem-solving (CPS) in the training of public management specialists. The aim of this study is to identify specific competencies among public management professionals that can be cultivated through the CPS approach and to explore the critical conditions for its successful implementation. The analysis was conducted at the Military Academy of Lithuania, where CPS techniques have been consistently integrated into public management-related subjects for several years, forming a stable foundation for the in-depth investigation. First, the study examines Lithuania’s legal framework for public management and public management education to implement CPS. Second, a qualitative data analysis of open-ended feedback (n = 199) highlights practical application. The findings reveal that the Lithuanian legal context underscores the importance of fostering creativity and innovation among public managers. Furthermore, the practical integration of CPS into public management curricula promotes modern bureaucratic qualities such as teamwork, critical thinking, problem-solving, creativity, innovation, and leadership. However, effective CPS implementation requires additional curriculum time, a supportive and creative learning environment, and strong teacher and student commitment. These findings underscore CPS’s potential as a valuable tool for cultivating public management competencies.
Acknowledgment The study is financed from the funds of the study-supporting project “Research on the Management of Security and Defense Institutions of Small States” (General Jonas Žemaitis Lithuanian Military Academy, 2020-12-17, No. V-828).
Pd-Catalyzed Suzuki-Miyaura Cross-Coupling Reaction in Glycerol Using KOH as Base and Glycerol-Triethanolamine Deep Eutectic Solvent under Inorganic Base‑Free Conditions
Authors: Monteiro Adriano , Hussain Zahid , Eichler Tatiana , Leal Bárbara
Published: December 2023

Glycerol and glycerol-triethanolamine deep eutectic solvent are both environmentally benign, cost-effective, and practical solvents for the Pd-catalyzed Suzuki-Miyaura cross-coupling of aryl halides with arylboronic acids. Utilizing KOH as base, the reaction in glycerol proceeded smoothly with low catalyst loadings (up to 0.5 mol% of PdCl2(PPh3)2) providing excellent yields (up to 99%) of the cross-coupling products, which can be readily extracted with hexane. However, the recyclability of the glycerol medium containing the catalyst is limited to a few cycles. Furthermore, it was explored the use of chlorodiphenylphosphine as a pre-ligand. Although glycerol phosphinite was not generated in situ, PPh2Cl proved to be an excellent pre-ligand, yielding the coupling product with a 98% yield. Compared to glycerol, glycerol-triethanolamine deep eutectic solvent (TEOA:G DES) proves to be a superior solvent for the cross-coupling reaction. In addition, the presence of amine group in the solvent allowed to obtain an inorganic base-free cross-coupling protocol. Aryl bromides and aryl boronic acids containing both electron releasing and attracting functional groups can be coupled without requiring the addition of any further base, affording the biphenyl products in moderate to good yields. The cross-coupling products can be easily isolated by extraction with hexane. Moreover, we observed the formation of triethanolamine phenylboronate during the reaction. The triethanolamine boronate was subsequently synthesized through the condensation of phenylboronic acid with triethanolamine and fully characterized. 11B nuclear magnetic resonance (NMR) spectroscopy confirmed the coordination of the nitrogen to the boron atom of the triethanolamine boronate.

Finalmente, se analizan los conceptos de completitud y de legitimidad del sistema normativo, con el fin de definir el alcance institucional que debe poseer un sistema jurídico sobre los subsistemas culturales del sistema social.
Desconocimiento del precedente: ¿defecto derivado de la inadecuada producción escritural de algunas sentencias?
Authors: Pérez Zapata Juliana , Guzmán Durán Mauricio
Published: December 2023

En el estudio del derecho es común encontrarse con sentencias extensas, confusas, redundantes y muy conceptuales sobre un caso en particular, características que usualmente dificultan la comprensión de la motivación que en ellas reside para el lector. Esta problemática afecta directamente la debida administración de justicia en Colombia cuando los contenidos escriturales y argumentativos de las providencias judiciales vislumbran tener una falla estructural que impacta indirectamente el resto de la jurisprudencia en el país. En este artículo se exponen los hallazgos arrojados por una investigación cualitativa realizada alrededor de un análisis profundo que abordó 10 sentencias que establecen precedente de la Corte Constitucional entre los años 2005 y 2021. En los resultados se da cuenta de cómo la producción escritural de las mismas afecta de primera mano la aplicación o el desconocimiento de la ratio decidendi de los precedentes por los jueces de menor grado de conocimiento en el ejercicio de sus funciones.

El objeto del presente artículo se centra en realizar análisis de los tributos saludables establecidos en Colombia, desde una perspectiva comparativa con el ordenamiento jurídico mexicano y de las discusiones que se han presentado entorno a sus efectos socioeconómicos y el cumplimiento de los principios constitucionales del derecho tributario. La investigación tiene un enfoque cualitativo, bajo el método documental y del derecho comparado. Como instrumento se utilizó la matriz de análisis documental. En la fundamentación teórica se abordan los elementos y principios de la tributación en Colombia, se señalan los diferentes fundamentos y discusiones planteados sobre dicho impuesto, pero además, se examina la forma como se incorporaron en la legislación mexicana y su impacto tanto en la economía como también en la política pública de salud, posteriormente se abordan las diferencias y similitudes frente a la forma en que se incorporaron en la legislación colombiana y finalmente se plantean las conclusiones y recomendaciones.
Integrando los registros de 50 años de investigación: arqueología del paisaje rural en Astigarribia (Gipuzkoa, País Vasco)
Authors: Narbarte Josu , Iriarte Eneko
Published: December 2023

Las últimas décadas han presenciado un notable desarrollo de las investigaciones e intervenciones arqueológicas de urgencia en el medio rural del País Vasco. Ello ha generado un gran volumen de datos, que sin embargo resultan a menudo parciales y fragmentarios. Este artículo propone adoptar una perspectiva de paisaje, basada en una integración multiescalar de distintas fuentes de información, para afrontar esta dificultad. Esta aproximación se ha testado en Astigarribia, una localidad que cuenta con un importante volumen de fuentes documentales y registros arqueológicos y arqueosedimentarios, revelándose de gran utilidad para trazar una evolución diacrónica de la sociedad local y su relación con el medio. Los resultados obtenidos invitan, por tanto, a ampliar este tipo de estudios a otras localidades, con el fin de optimizar los registros existentes.
Berbegirada bat Gipuzkoako megalitoen baitan

A lo largo de la historia en Euskal Herria siempre se han mezclado historia y mitología, añadiendo que el valor que ofrece el pensamiento popular es innegable. Formando parte de la identidad cultural, no podemos prescindir del significado del origen de muchos elementos patrimoniales que podemos encontrar en las montañas, y una cultura que ha llegado transmistida de generación en generación. El paisaje megalítico es uno de los modelos más claros de este interés. Las investigaciones realizadas en Gipuzkoa han sido de gran importancia, convirtiéndose en una de las principales líneas de investigación arqueológica. Dentro del paisaje megalítico de Gipuzkoa, el origen de estos monumentos ha sido motivo de estudio durante mucho tiempo, en cambio, su evolución en épocas posteriores y su ocupación ha sido relegada a un segundo plano. Tomando esto como base y como elementos que se mantienen en el espacio, a lo largo de estas líneas se analizarán las variantes de significado que sucederán tanto en la evolución como ante una sociedad que experimenta su desarrollo. Centrados en la reutilización de estos espacios, el material disponible puede mostrarnos la transformación o repetición de significados, generando memoria. La gestión de las mismas, sobre todo aquellas que se identifican como patrimonio, será una oportunidad para analizar cómo las entiendes locales se han adaptado en la actualidad ante estos elementos.

This study is a literature review study that aims to see the role of job satisfaction on turnover intention, especially in start-up companies. Start-up companies today have the opportunity to grow rapidly supported by technology and information. Many interesting things can be reviewed from start-up companies, one of which is that start-up companies are dominated by Gen Z and millennials. Where generation Z and millennials are known for their characteristics or attitudes that easily feel bored when they can't get the opportunity to develop and easily feel bored with monotonous types of work. So that this triggers the emergence of turnover intention, including start-up companies. For this reason, it is necessary to make efforts to minimize the emergence of turnover intention through increasing and understanding what factors can increase job satisfaction so as to minimize the emergence of turnover intention from each individual in the start-up organization.
Modeling the water security in a watershed using the water footprint concept and water scarcity indicators

Water scarcity has received global attention in the last decade as it challenges food security in arid and semi-arid regions. This study employs water scarcity indices to assess water resources in the agricultural sector of Iran's Jazmourian watershed. Overall, we find that the watershed is experiencing a “very high stress” water situation. This is primarily due to intensive water usage for diverse crops, which has resulted in a negative net virtual water balance and contributed to a rise in water stress and poverty levels. The water stress index is 0.88, and the agricultural water stress is 1.25. The agricultural water footprint is 2,018.53 million cubic meters (MCM), with the share of blue, green and gray water footprints being 80.21, 6.08, and 13.72%, respectively. The region possesses 3,210 MCM of available water for crops, with 17.1% sourced from green waters and 82.9% from blue waters. Despite low annual rainfall and limited water resources, the region excessively exploits water for diverse crops. The net virtual water balance is negative, indicating high virtual water export (1,112–1,605 MCM) compared to imports (58–265 MCM). With declining water availability and increasing crop production, the region experiences rising water stress. The spatial analysis of sub-watersheds reveals diverse patterns of water stress and poverty, as detailed in the study.
Plądrofonia – koncepcja kolażu muzycznego
Authors: Barszcz Marcin
Published: December 2023

Celem poniższego artykułu jest zaprezentowanie zapomnianego dziś zjawiska plądrofonii. Omawiane zagadnienie jest awangardowym podejściem do odbioru i wykorzystywania cudzych dzieł muzycznych w celu nadania im nowych znaczeń, poprzez stworzenie własnych wersji. Efekty plądrofonii można przyrównać do kolaży muzycznych. Autor zestawia tę koncepcję z samplingiem, który jest powszechnym działaniem na współczesnym rynku muzycznym. Przedstawiana jest postać Johna Oswalda, autora opisywanego pojęcia, jego filozofia i efekty działań. W tym kontekście wprowadzone zostaje pojęcie aktywnego słuchania. Autor omawia także postać Christiana Marclaya, który jako obiekt przetworzeń plądrofonicznych wybrał nośniki dźwięku – głównie płyty winylowe. W tekście znajduje się także opis narzędzi wykorzystywanych przez autorów dzieł plądrofonicznych. Poruszony zostaje aspekt konsekwencji prawnych działań Oswalda, z jednoczesnym wprowadzeniem pojęcia kultury remiksu, wymyślonym przez Lawrence’a Lessiga. Autor przywołuje też przykłady dzieł plądrofonicznych na współczesnym rynku muzycznym oraz duchowych spadkobierców plądrofonii, których możemy odnaleźć w przestrzeni kultury internetowej.

Os Institutos Federais de Educação, Ciência e Tecnologia desempenham um importante papel na democratização da educação no Brasil, porém, enfrentam uma alta taxa de evasão, especialmente em cursos não obrigatórios. Em contrapartida, ampliou-se o foco para além da correção da evasão e reprovação, considerando a permanência bem-sucedida como referência para o desenvolvimento de políticas educacionais. Nessa conjuntura, este estudo, por meio de uma pesquisa documental exploratória e qualitativa, analisa as diretrizes que norteiam as políticas de acesso, permanência e êxito do Instituto Federal Fluminense. Destaca-se que a instituição tem proporcionado condições favoráveis para a universalização não apenas do acesso, mas da permanência e êxito, dispondo de uma variedade de tipos de suporte, bem como implementando práticas que favorecem a qualidade das experiências educacionais. O estudo traz implicações sobre a ação de gestores e professores desta e de outras instituições acerca das políticas institucionais e práticas pedagógicas para a Educação Profissional e Tecnológica.
