Mechanical and Durability Characteristics of Eco-Friendly Fly Ash Bricks
Authors: G Chidananda
Published: November 2021

Abstract: This paper presents an experimental investigation carried out on eco-friendly fly ash bricks having various percentage of fly ash, lime, gypsum, stone dust, coarse aggregate and boiler slag. Raw materials are added to the pan mixer with different mix proportions and are mixed thoroughly with water until a homogeneous mixture is formed. Prepared homogeneous mixture is fed into the press and moulded to a brick of size 200 x 200 x 300 mm using vibro-hydraulic press. Moulded bricks are air dried for 24 hours, arranged in stacks and are cured for a period of 28 days by sprinkling the water to achieve the optimum strength. Compressive strength, water absorption, efflorescence, dimension tolerance and density tests are conducted as per BIS codal provisions. Eco friendly fly ash bricks having varying proportions of industrial by-products with less content of stone dust satisfy compressive, water absorption, efflorescence, dimensional tolerance and density requirements as per BIS codal provisions and can be used in structures as a sustainable construction material. Keywords: Eco-friendly fly ash bricks, Compressive strength, Water absorption, Efflorescence, Dimension tolerance and Density

Authors: G Chidananda
Published: November 2021

Abstract: This paper presents an experimental investigation on influence of different curing methods on the performance of M30 grade concrete. Different curing methods such as air curing, pond curing, intermittent curing, gunny bags curing, chemical curing and using Super Absorbent Polymer (SAP) by 0.3% of weight of cement are considered. Slump and compacting factor tests are performed to know the workability of fresh concrete. Compressive strength of hardened concrete is determined for concrete specimens cured by different curing methods. Durability in terms of carbonation resistance on hardened concrete is also performed as per IS 516 (Part 5/Sec 3, 2021) codal provisions. Depending upon the site conditions and availability of potable water, curing methods such as pond curing, intermittent curing, gunny bags curing, chemical curing and SAP curing can be adopted in site to achieve the expected strength and durability requirements. Keywords: Curing methods, Compressive strength and Carbonation resistance.

Authors: Arifin Samsul , Sayifullah Sayifullah
Published: November 2021

This study aims to see whether the process of export and import convergence occurs with the control variable of the size of the country's economy affected by the COVID-19 pandemic as measured by GDP and spatial interactions. The method of analysis in this study uses the Spatial Dynamic Panel. The research objects are 64 countries affected by the COVID-19 pandemic—data taken in the period 2019q4-2020q3. The results show that GDP and spatial elements influence the process of export and import convergence. The speed of convergence and the length of time to reach a steady-state, imports are better than exports reaching 28-38% with about one semester and reaching 15-16% with a duration of 1 year (export model). Exports and imports during the COVID-19 pandemic reflect interactions between countries, with distance as a determining factor. However, the role of interaction between countries tends to be insignificant in the long run.
Innovation And Entrepreneurship For Competitiveness In The ASEAN: An Empirical Analysis
Authors: Aisyah Hesty , Saputra Nopriadi
Published: November 2021

ASEAN economies face new challenges in achieving sustainable, inclusive development, namely entrepreneurial innovation, impacting ASEAN's competitiveness. This research investigates the relationship between the power of innovation, entrepreneurship, and national competitiveness at the ASEAN country level. This study also examines how innovation and entrepreneurship can affect a country's competitiveness and inclusive development. The results of the comparative analysis based on means-testing using an independent sample t-test at the ASEAN level show a significant difference between the group of countries with a low-medium level of innovation ability and the group of countries with a high level of innovation ability. High levels of innovation imply that these countries have high competitiveness, entrepreneurship, and inclusive development levels. Meanwhile, the regression and correlation analysis results show that several ASEAN countries have high national competitiveness due to high levels of innovation, entrepreneurship, and inclusive development. The findings of this study may help develop policies to boost national competitiveness in inclusive growth.

Authors: Andriani Rian , Disman Disman , Ahman Eeng , Santoso Budi
Published: November 2021

The hospitality industry in Indonesia is growing rapidly but lagging behind the readiness of human resources. The hotel industry has a crucial problem of retaining employees where there is a gap between the interests of employees and the interests of the company. Turnover intention is the main predictor of turnover, so aspects that can affect turnover intention will affect turnover. This study aims to describe and analyze the relationships between variables and dimensions in the research model or paradigm developed by the researcher. It tested the conditional process model using path analysis based on OLS regression and bootstrap methods. The population in this study were employees of the hotel industry in Indonesia, with a sample of 257 employees. The findings of this study are that the work environment has no direct effect on the variables of job satisfaction, employee engagement, and turnover intention but can interact as a moderator variable so that it effectively moderates the impact of polychronic on turnover intention through full mediation of job satisfaction and employee engagement.

Entanglement marginal problems
Authors: Navascués Miguel , Baccari Flavio , Acín Antonio
Published: November 2021

We consider the entanglement marginal problem, which consists of deciding whether a number of reduced density matrices are compatible with an overall separable quantum state. To tackle this problem, we propose hierarchies of semidefinite programming relaxations of the set of quantum state marginals admitting a fully separable extension. We connect the completeness of each hierarchy to the resolution of an analog classical marginal problem and thus identify relevant experimental situations where the hierarchies are complete. For finitely many parties on a star configuration or a chain, we find that we can achieve an arbitrarily good approximation to the set of nearest-neighbour marginals of separable states with a time (space) complexity polynomial (linear) on the system size. Our results even extend to infinite systems, such as translation-invariant systems in 1D, as well as higher spatial dimensions with extra symmetries.
EXPLORING THE IMPLEMENTATION OF AN INTERVENTION FOR A PUPIL WITH MATHEMATICAL LEARNING DIFFICULTIES: A CASE STUDY
Authors: Chin Kin Eng , Fu Sai Hoe
Published: November 2021

This study presents a single case study of how a remedial mathematics teacher incorporated an instructional intervention into her teaching practices in order to teach counting to a pupil with mathematical learning difficulties. This new theory-driven intervention was developed by the authors of this study. Dyscalculia is a term which refers to a wide range of mathematical learning difficulties or disabilities. Dyscalculic pupils have a specific mathematics learning disorder with a core deficit in representing and processing of numerosity. They might not be able to recognise numerical quantities, performing counting and so on. Early supports such as interventions have a great potential in helping dyscalculic pupils to improve mathematical skills. However, there remains a lack of appropriate instructional scaffolds to help dyscalculic pupils to organise their learning structures by addressing both cognitive deficits and mathematical skills. The present study involves a primary school remedial teacher, Daisy, and an at-risk dyscalculic pupil, David, both pseudonyms. Data were collected through interviews, lesson observations, and reflective journals. The findings revealed that the proposed intervention improved the counting ability of the pupil.

Perubahan iklim dapat berpengaruh terhadap peningkatan risiko penularan khususnya penyakit demam berdarah dengue (DBD). Kajian mengenai perubahan iklim khususnya suhu, kelembaban, dan curah hujan diperlukan guna kewaspadaan dini peningkatan kasus DBD. Sumber data menggunakan data penelitian “Kejadian DBD berdasarkan faktor iklim di Kota Ternate”. Analisis menggunaan analisis jalur untuk menjelaskan mekanisme hubungan kausal antara curah hujan, kelembaban udara, suhu udara terhadap kejadian penyakit DBD. Kasus DBD di Kota Ternate ditemukan relatif lebih tinggi pada bulan basah yaitu kisaran curah hujan > 200-412 mm, suhu 23-27oC dan kelembaban 67-82 mmHg. Suhu dan kelembaban dinyatakan berpengaruh secara signifikan pada kasus DBD di Kota Ternate (p value<0,005). Curah hujan meskipun tidak terbukti berpengaruh pada kasus DBD, akan tetapi berdasarkan diagram jalur, curah hujan berpengaruh positif terhadap kejadian penyakit DBD sebesar 8,4% yang berarti bahwa tinggi rendahnya kejadian DBD dipengaruhi oleh curah hujan sebesar 84%. Hal ini disebabkan karena curah hujan berpengaruh langsung terhadap keberadaan tempat perkembangbiakan nyamuk vektor DBD. Diperlukan kerjasama antara instansi kesehatan dengan BMKG guna sistem kewaspadaan dini peningkatan kasus DBD dengan memperhatikan tren fluktuasis suhu, kelembaban, dan curah hujan.

Banyak faktor dapat mempengaruhi kejadian malaria. Faktor tersebut berasal dari perubahan kondisi lingkungan itu sendiri. Kondisi lingkungan mempengaruhi kepadatan Anopheles spp. di dalam rumah yang kontak dengan manusia. Kondisi tersebut berupa suhu udara. Suhu udara yang hangat mempercepat siklus hidup nyamuk sehingga meningkatkan kepadatan nyamuk di dalam rumah. Besarnya kepadatan nyamuk per orang per jam akan meningkatkan frekuensi kontak antara vektor dan manusia. Penelitian ini bertujuan untuk mengidentifikasi serta memetakan habitat perkembangbiakan potensial larva Anopheles. Penelitian dilakukan secara potong lintang di Kelurahan Kemelak Bindung Langit Kecamatan Baturaja Timur pada bulan Agustus 2018.  Sebagai populasi adalah habitat perkembangbiakan larva Anopheles yang potensial seperti sawah, kolam, rawa, aliran sungai yang tidak deras dan parit. Pengumpulan data dilakukan dengan mengamati habitat potensial larva Anopheles yang terdiri dari jumlah larva dan mengamati lingkungan fisik biologinya. Pengamatan larva Anopheles dilakukan dengan metode pencidukan larva.  Hasil dari penelitian ini adalah jenis habitat perkembangbiakan  larva Anopheles di Kelurahan Kemelak Bindung Langit adalah rawa dan kolam dengan kepadatan larva berkisar 30-110 ekor. Suhu air pada habitat perkembangbiakan berkisar 29oC-30oC. Seluruh habitat perkembangbiakan larva Anopheles tidak terkena paparan sinar matahari langsung. Kadar garam pada habitat perkembangbiakan yaitu 0‰. Luas habitat berkisar 21m2-2400m2, dengan memiliki pH masing- masing pada habitat yaitu 6.

Molecular defense responses to natural enemies determine seedling survival in a subtropical forest
Authors: Shang Hui , Wang Yunquan , Han Baocai , Bongers Franca , Mi Xiang-Cheng , Chen Lei , Liang Yu , Ma Keping
Published: November 2021

Negative density dependence (NDD) has been accepted as a key mechanism
for biodiversity maintenance in natural forests and different lineages
of natural enemies (fungus, bacterium, insect and virus) may be
involved. Previous NDD related studies usually correlated seedling
survival to the density of host-specific pests or pathogens along the
distance to conspecific neighbors, and molecular defense responses of
focal seedlings to natural enemies were seldomly concerned. By employing
community functional genomics strategy, we extracted copy numbers of
homologous genes in defense responses from transcriptomic data of 99
tree species and their inherent impacts on seedling survival were
evaluated using partial linear regression analysis and general linear
mixed-effects models. The community-level transcriptomic gene copy
number of defense responses to fungus, insect and virus showed
significant negative correlations with survival rates of the seedling
community and the species-level gene copy number of defense response to
insect significantly correlated with survival rates of top-twenty common
seedling species. Moreover, presence of adult neighbors with distinct
defense response to bacterial and viral pathogens survival of focal
seedlings as predicted by NDD, while presence of seedling neighbors with
similar defense response to insect tended to promote survival of focal
seedlings which may be driven by insect-mediated biotic filtering or
competitive exclusion. We conclude that both gene copy number and
dissimilarities to adult and seedling neighbors in defense response to
natural enemies determined seedling survival, indicating the critical
contributions of molecular defense responses of plants to species
coexistence and diversity maintenance in subtropical forests.

Extensive introgression despite Haldane’s rule: insights from grasshopper hybrid zones
Authors: Hagberg Linda , Celemin Enrique , Irisarri Iker , Hawlitschek Oliver , Bella J L , Mott Tamí , Pereira Ricardo
Published: November 2021

Although the process of species formation is notoriously idiosyncratic,
the observation of pervasive patterns of reproductive isolation across
species pairs suggests that generalities, or “rules”, underlie species
formation in all animals. Haldane’s rule states that whenever a sex is
absent, rare or sterile in a cross between two taxa, that sex is usually
the heterogametic sex. Yet, understanding how Haldane’s rule first
evolves and whether it is associated to genome wide barriers to gene
flow remains a challenging task because this rule is usually studied in
highly divergent taxa that no longer hybridize in nature. Here, we
address these questions using the meadow grasshopper Pseudochorthippus
parallelus where populations that readily hybridize in two natural
hybrid zones show hybrid male sterility in laboratorial crosses. Using
mitochondrial data, we infer that such populations have diverged some
100,000 years ago, surviving multiple glacial periods in isolated
Pleistocenic refugia. Nuclear data shows that secondary contact has led
to extensive introgression throughout the species range, including
between populations showing hybrid male sterility. We find repeatable
patterns of genomic differentiation across the two hybrid zones, yet
such patterns are consistent with shared genomic constraints across taxa
rather than their role in reproductive isolation. Together, our results
suggest that Haldane’s rule can evolve relatively quickly within
species, particularly when associated to strong demographic changes. At
such early stages of species formation, hybrid male sterility still
permits extensive gene flow, allowing future studies to identify genomic
regions associated with reproductive barriers.
Chronic Liver Diseases: From Development to Novel Pharmacological Therapies
Authors: Borrello Maria , Mann Derek
Published: November 2021

Chronic liver diseases comprises a broad spectrum of burdensome diseases
that still lack effective pharmacological therapies. Our research group
focuses on Fibrosis which is a major precursor of liver cirrhosis.
Fibrosis consists in a progressive disturbance of liver sinusoidal
architecture characterised by connective tissue deposition as a
reparative response to tissue injury. Multifactorial events and several
types of cells, participate in fibrosis initiation and progression and
the process still needs to be completely understood. The development of
experimental models of liver fibrosis alongside the identification of
critical factors progressing fibrosis to cirrhosis will facilitate the
development of more effective therapeutic approaches for such condition.
This review provides an overlook of the main process leading to hepatic
fibrosis and therapeutic approaches that have emerged from a deep
knowledge of the molecular regulation of fibrogenesis in the liver.
Exosome-based immunotherapies in ovarian cancer development of preclinical models and therapeutics
Authors:   , Pisano Simone
Published: November 2021

Treatment of ovarian cancer (OC) continues to present clinical challenges. It remains difficult to diagnose early stage disease, and because of this generally presents as advanced stage, with limited therapeutic options and often the development of resistance to chemotherapy. Furthermore, OC is considered as an immunologically “cold” tumour based on the poor response to immunotherapies. This lack of response to immunotherapy remains poorly understood, hence better models are needed in order to elucidate the fundamental mechanisms behind tumour immunosuppression, and for new and innovative therapeutic strategies to be tested. Exosomes have recently emerged as crucial players in the cell-cell communication and content exchange within the tumour microenvironment and have also been investigated for their capacity to act as cancer therapeutics or to be re-engineered to increase their performances and effects. In this work, two main research areas were explored. The first one focused on advanced ovarian cancer modelling. Indeed, the in vitro formation of multicellular spheroids that included a mixture of cancer cells and different macrophage phenotypes was optimised, and their characteristics explored. Additionally, an in vivo advanced OC model was created from immunocompetent mice and the tumours were characterised for their immune infiltrates presence. The ascitic fluid that arose from the tumour-bearing mice was also comprehensively analysed for its immune cells content by mass cytometry for the first time in an ovarian cancer setting. The second part of the work involved the exploration of two innovative OC therapeutics. Dendritic-cell (DC) derived exosomes were obtained from tumour antigen-pulsed DCs and tested for their efficacy both in vitro and in vivo. A semi-synthetic exosomes approach was also tested by forcing monocytic cells through pores of different sizes and obtaining Immune (Cell) Derived Exosome Mimetics (IDEM). IDEM were characterised and tested in vitro on both 2D and spheroid systems.

Authors: Parveen Khashiya , Vishwakarma Prof. Shravan
Published: November 2021

Hybrid energy generation which includes both wind and solar energy has grown exponentially in latest years, and this will continue. Power quality problems such as voltage-swells, voltage-sags, harmonic components, power factor, and inadequate voltage control are caused by intermittent various exposures and the incorporation of wind-turbine and Photo-voltaic power generating systems with the grid. A Static Compensator (STATCOM) is employed to enhance power-quality. The power quality enhancement method for grid-connected wind-turbine and photo voltaic power plants employing STATCOM is introduced in this paper.  The framework of the proposed methodology describes in order to improve the transient voltage stability of the large-scale wind / solar hybrid system, the STATCOM reactive power compensation device is connected to the grid.   The compensator is offered to further improve output parameters such as voltage THD, current THD and active power.

Diversity in the East-Central European Borderlands
Authors: Narvselius Eleonora
Published: November 2021

Built on up-to-date field material, this edited volume suggests an anthropological approach to the palimpsest-like milieus of Wrocław, Lviv, Chernivtsi, and Chişinău. In these East-Central European borderline cities, the legacies of Nazism, Marxism-Leninism, and violent ethno-nationalism have been revisited in recent decades in search of profound moral reckoning and in response to the challenges posed by the (post-)transitional period. Present shapes and contents of these urban settings derive from combinations of fragmented material environments, cultural continuities and political ruptures, present-day heritage industries and collective memories about the contentious past, expressive architectural forms and less conspicuous meaning-making activities of human actors. In other words, they evolve from perpetual tensions between choices of the past and the burden of the past.
A novel feature of this book is its multi-level approach to the analysis of engagements with the lost diversity in historical urban milieus full of post-war voids and ruptures. In particular, the collected studies test the possibility of combining the theoretical propositions of Memory Studies with broader conceptualizations of borderlands, cosmopolitan sociality, urban mythologies, and hybridity. The volume’s contributors are Eleonora Narvselius, Bo Larsson, Natalia Otrishchenko, Anastasia Felcher, Juliet D. Golden, Hana Cervinkova, Paweł Czajkowski, Alexandr Voronovici, Barbara Pabjan, Nadiia Bureiko, Teodor Lucian Moga, and Gaelle Fisher.
Implementation Challenges of Community Directed Treatment with Ivermectin Program for Control of Onchocerciasis in Ulanga, Tanzania
Authors: Mushi Vivian
Published: November 2021

Background: Community drug distributors (CDDs) have a crucial role in distributing ivermectin for onchocerciasis control and prevention. Their roles, experiences and challenges faced in the implementation of community-directed treatment with ivermectin (CDTI) programme could potentially affect coverage, consequently leading to persistent transmission. Therefore, this study aimed to explore the experience and the roles which CDDs plays in implementation of community directed treatment with ivermectin program for onchocerciasis control in Ulanga, Tanzania. Methods: A cross-sectional study design was used to collect qualitative data in 2018 in Ulanga district, Tanzania. Five community drug distributors were purposively selected for in-depth interviews. Thematic framework approach for qualitative data analysis was used to generate codes, categories and themes. Results: Out of the five community drug distributors interviewed, two had experience of 15 to 20 years on implementation of the community directed treatment with ivermectin programme while the remaining community drug distributors had experience of less than 10 years. The main challenges faced by CDDs in the implementation of the CDTI programme include; the geographical location of the hamlets (hard to reach hamlets), long distances between houses, low compliance of community members to medication due to fear of side effects experienced before and mistrust of methods of dose calculation, short time of drug distribution and absence of people from their households as the exercise was conducted when community members were involved in agricultural activities. Conclusions: The challenges faced in the implementation of the CDTI programme could negatively affect the distribution and coverage of ivermectin treatment in the Ulanga district. It’s now an opportune time to address the challenges that CDDs are facing in the implementation of the CDTI programme to ensure effective control of onchocerciasis in the district.

Background: There is limited access to health services in Burundi, as most of the services such as cancer care are unavailable. Burundian citizen who can afford the costs involved in seeking treatment elsewhere are referred abroad. The purpose of this study was to assess the proportion of patients suffering from cancer among patients referred abroad for healthcare and to evaluate the costs incurred by those patients in relation to what the country would save by establishing cancer healthcare facilities. Methodology: The study was performed retrospectively from January 2016 to December 2018. With approval of Ministry of Public Health and AIDS control, the data was collected from medical reports at the general management of health facilities and AIDS control office. All patients with medical reports containing the reason for referral were included in the study. Medical reports assessing occupational disability were excluded. Data analysis was performed using Statistical Package for the Social Sciences (SPSS). Results: Male, female and unclear was 45.3%, 39.9% and 14.8% respectively. Average age was 31,82. The main reason for referral was MRI (21.7%). Cancer patients represented 18% of all patients referred abroad for healthcare and the most common type of cancer found was breast (26.5%), genitourinary (15.7%) and digestive (14,2%). If all patients from 2016-2018 were referred to Kenya, Uganda, Rwanda, India or Europe for 30 years, the country would spend in foreign currency US$3,858,229; US$638,342.80; US$21,288,592; US$10,410,192.90; US$54,718,329.70 respectively. Also, if all patients estimated by Globocan in 2018 were to be referred to these countries, the cost of foreign currencies would be US$52,455,122.60; US$38,264,740.88; US$129,272,590.40; US$81,330,325.94; US$276,601,008.02 respectively. Conclusion: There is a good number of cancer patients among patients referred abroad for health care. The estimated costs incurred by patients referred abroad for cancer care are far greater than funds needed to setup modern cancer care centres in Burundi.
Control de velocidad de un motor de reluctancia variable de 4 fases y 6 polos, utilizando técnicas de control clásico
Authors:   , González San Román Jesús Daniel
Published: November 2021

In this work, the analysis and design of a speed control system of a variable reluctance motor with six poles and four phases is presented. The nonlinear motor model includes the nonlinearity of the Coulomb friction plus the viscous friction. The structural analysis of the non-linear model is carried out, which is linearized at the operating point established at 2000rpm. Both the non-linear and linear models are compared both in their structure and in their responses through digital simulations, finding that under certain conditions both have similar behaviors. Subsequently, based on the linear model, a classic PI controller is designed and subjected to regulation, tracking and load torque variation tests. The controller design is carried out using the Bode shaping technique, guaranteeing adequate gain and phase margins with a higher bandwidth than the mechanical subsystem mode. The robustness is verified by means of the digital simulation of the control system using the non-linear model, which is also subjected to load variations, finding that the PI controller has excellent performance in both regulation and tracking. Finally, two additional controllers are proposed: the first is a PII controller, the objective of which is to reduce the effect of the non-linearity called dead zone present in the motor at start-up or at low speeds. The second is a PI controller that adds a new technique for reducing the ripple present in the speed and torque responses, characteristics of this type of motor.

La deslealtad de Pedro de Mena con la Capilla Real de Granada: a propósito del busto-relicario del Ecce Homo
Authors: Gila Medina Lázaro
Published: November 2021

Presentamos uno de los episodios totalmente desconocidos de la Capilla Real de Granada durante parte del siglo XVII. Se trata de la conversión del espejo-custodia de la reina Isabel en relicario para un supuesto clavo de la cruz de Cristo, en contra del parecer de los capellanes reales, quienes lucharán para que retornara a ostensorio, sin marginar el clavo para el que encargarán un busto de Ecce Homo a Pedro de Mena (1628-1688). El artista, según lo hasta ahora conocido, al irse a Málaga, en 1658, no lo había hecho, realizándolo Bernardo Francisco de Mora (1614-1684).
Perspectivas emergentes en el arte cerámico. Análisis de la obra de Rafa Pérez y Gregorio Peño
Authors: Serra María Florencia , Paltrinieri Agustina , Rendtorff Nicolás
Published: November 2021

Al ser una práctica milenaria, el arte cerámico cuenta con un legado histórico que reúne saberes, modos de hacer y concepciones tradicionales. Como toda trayectoria histórica presenta continuidades y rupturas en sus permanentes actualizaciones. El presente trabajo analiza el surgimiento de una estética del arte cerámico actual que propone desplazamientos respecto a la relación sujeto-materia y una revisión de los modos de concebir la materialidad cerámica. Para ello analizaremos las propuestas artísticas de dos consagrados ceramistas contemporáneos: Rafa Pérez y Gregorio Peño. Atenderemos la articulación entre los procesos constructivos, los resultados formales y algunos pronunciamientos de los artistas que nos permitan reconocer sus posicionamientos. De este análisis se desprende que los comportamientos de la materia, sus reacciones y contingencia, cobran un rol protagónico en estas propuestas artísticas. Reconocemos allí la resonancia de estas nuevas tendencias que nos permiten delinear un giro materialista en el arte cerámico.
El primitivo tabernáculo pétreo de Nuestra Señora de la Antigua de la catedral de Sevilla (1630-1632)
Authors: Santos Márquez Antonio Joaquín
Published: November 2021

En este artículo se aborda la historia del primitivo retablo pétreo de la Virgen de la Antigua de la catedral de Sevilla, punto de partida del actual de Pedro Duque Cornejo y conocido a través de una estampa de Pedro Rodríguez, del cual, gracias a una novedosa documentación, damos a conocer que fue financiado con limosnas de los capitulares catedralicios a partir de 1630, diseñado probablemente por Miguel de Zumárraga y levantado definitivamente entre 1631 y 1632.
La imagen sigilar: el sello del Estudio de Salamanca
Authors: Lahoz Lucía
Published: November 2021

Análisis del sello de la Universidad de Salamanca, concedido por Alejandro IV como primera imagen institucional, identitaria y autentificadora. La técnica, tipología e iconografía figurativa de la imagen se implican en su funcionamiento social e ideológico. El sello es la matriz y su impronta en todo tipo de soportes, desde documentos que ratifican el sistema de la universidad y difunden su imagen en lugares lejanos, hasta las fachadas monumentales que la proyectan en la propia urbe. En la Fachada Rica salmantina, la imagen proclama y actualiza la titularidad papal representando una escena diplomática ad vivum, empleando una retórica visual plena de intención cuando la universidad pugna por su estatus y autonomía frente a las instituciones catedralicias y monárquicas.
Ficciones hacia lo posible: por una política feminista afirmativa
Authors: Fraga Costa Sabela
Published: November 2021

Este artículo se propone analizar las posibilidades de transformación del feminismo en el campo de las imágenes desde la lógica vital desarrollada por Victoria Sendón de León y desde la política afirmativa de Rosi Braidotti. El movimiento feminista supo identificar la capacidad de agencia de las imágenes y el peso de éstas en la creación de significados y valores. Por este motivo, lo visual se enmarcó siempre dentro de una estrategia creativa para subvertir la mirada hegemónica, pero intentando también que las representaciones tuvieran su efecto material en las vidas de las mujeres. Para ilustrar esta argumentación, las propuestas artísticas se centran en el reto de la visibilidad lesbiana para demostrar cómo la ficción permite pensar y visualizar todo aquello que aún está por hacer.

La proyección del concepto de la "hispanidad" en la actividad arquitectónica del primer franquismo
Authors: Cabrera García M.ª Isabel
Published: November 2021

El régimen de Franco concedió un lugar relevante a la idea de la hispanidad, íntimamente ligada a su vocación imperial; idea que podía contribuir a fortalecer la identidad como país, y de cara hacia el exterior mantendría la ilusión de una proyección internacional que el régimen no tenía. En nuestro estudio nos aproximaremos a las fuentes históricas en las que se gesta la idea, a la reflexión teórica sobre la «hispanidad» en los primeros años del franquismo y a cómo se proyecta el mito en la arquitectura. Tal concepto llevaría asociados un arsenal de lugares, fechas, celebraciones, imágenes..., con fuerte carga simbólica, que fueron haciéndose muy presentes en todas las manifestaciones culturales, y por tanto en el arte, popularizándose concepciones, imágenes y tópicos. Adquirían así un valor especial los principales edificios, conjuntos monumentales y ciudades vinculadas con el relato del descubrimiento del Nuevo Mundo: Granada, La Rábida, Guadalupe o Trujillo, poniendo de manifiesto la apropiación ideológica que del patrimonio histórico realizó el nuevo Estado.
