Argivi, Persiani o Spartani? Gli
Eraclidi
di Euripide e le ‘storie intenzionali’ ateniesi
Authors: Valle Salazar Luca
Published: November 2023

Riassunto

Questo articolo discute l’immagine degli Argivi negli Eraclidi di Euripide, nonché il ruolo del dramma nella costruzione dell’identità della polis ateniese attraverso l’uso delle sue memorie collettive. Euristeo e gli Argivi rappresentano l’‘altro’ nella struttura drammatica, e nello specifico potevano rievocare la memoria dei Persiani di Dario e di Serse. In ultima analisi, in questo modo il dramma contribuisce a costruire una ‘storia intenzionale’ ateniese attraverso diverse dimensioni temporali (il passato del mito, il passato recente della polis, il suo presente e il suo futuro).

Published: November 2023

TheXXviri ex senatus consulto rei publicae curandaeplayed a decisive role in the civil war between Maximinus Thrax and the senate in 238. This note examines the actions of the extraordinary committee and interprets them against the backdrop of the reception of constitutional thought rooted in that, which was perceived as traditional political ideals of the Roman Republic during the Principate. The study will first look at the roots of the conflicts between Maximinus Thrax and theordo senatorius, followed by an analysis of the origins and tasks of theXXviri together with their political goals and possible republicanexempla. Finally, there will be observations on thevigintivirate’s significance and role after the senate’s triumph over its enemy. In doing so, this contribution will emphasize the importance of republican constitutional thought in times of crisis for the continued existence of theres publica romanaunder the Principate.

Published: November 2023

Radiative cooling technology with zero-energy consumption and zero-carbon emission has drawn enormous attention. However, the high-cost manufacture, limited scalability, and narrow application scopes remain major impediments to radiative cooling commercialization. Here, we present a bilayer PDMS/nanoPE fabricated by an automatic film applicator for high-performance passive daytime radiative cooling. The nanoPE underlayer maximizes the reflection of sunlight and the transparent PDMS top-layer dramatically enhances the infrared emissivity of pristine nanoPE across the atmospheric transparency window (∆E
8–13 μm = 0.85). The obtained PDMS/nanoPE simultaneously allows a high solar reflectance of 0.94 and a thermal emittance of 0.94, enabling a sub-ambient cooling of 4.5 °C with a maximum of 7.6 °C in rooftop test and a theoretical net cooling power of 65 W/m2. A distinct temperature reduction of more than 10 °C can be achieved in comparison with pristine PDMS film. Integration of the hydrophobicity, durability, robust mechanical strength, and industrial scalability, we believe this work will provide practical and efficient solutions to cooling vehicles, buildings, and the human body in a simple and low-cost manner.

Published: November 2023

Application of nano titanium dioxide (TiO2) in various fields such as advanced oxidation process (AOP) has led to the development of its preparation technologies. The sol–gel process is a widely used chemical wet method for preparing nanoscale TiO2 gels. This technique offers numerous advantages, such as the potential to produce large quantities of homogeneous materials with high purity, surface area, porosity, and reactivity, as well as being cost-effective, simple to implement, and capable of controlling the size and shape of the resulting particles. This review provides a comprehensive overview of the chemicals, reaction conditions, and procedures required for preparing nano TiO2 using the sol–gel method. It covers the selection of necessary compounds, such as TiO2 precursors, solvents, hydrolysis agents, and additives, along with their composition and sequences of adding, reaction order, and impact on the final product. Additionally, it provides detailed information on the routes of gel formation and ambient conditions, including temperature, humidity, stirring speed, injection rates of compounds, aging process, and storage conditions. This information serves as a basic reference for understanding the sol–gel process and the relative contribution rates of the influencing factors, which is essential for controlling the size, morphology, crystallinity, and other physicochemical properties of the resulting TiO2 gel/powder for targeted applications.

According to reports, the bioactive thiourea derivative was prepared from the ethanol solutions of thiourea and chloro acetic acid in a 1:1 M ratio. DFT calculations of 2-Imino-4-oxo-1,3-thiazolidine hydrochloride (IOTH) were performed with the use of B3LYP and the 6-311+G(2d,p) basis set. Frontier molecular orbitals, mapped electrostatic potential (MEP) map, and nonlinear optical (NLO) properties of the IOTH were all assessed. The compound was tested for drug-likeness using Swiss ADME. UsingB. pasteurii(PDB ID: 4UBP), calculations for molecular docking were then performed on the geometry-optimized structure. In order to determine the complex’s stability and the interactions between ligands and the receptor, the complex was subjected to molecular dynamics (MD) simulations. According to the results, the first hyperpolarizability value (β0) was 7.459 × 10−24 esu. The large first hyper polarization rate theoretically supported its use in the design of NLO materials. The calculated HOMO–LUMO energy gap value of the IOTH was found to be 2.87 eV. The small HOMO–LUMO energy gap suggested that IOTH is a soft molecule with a high degree of chemical reactivity but poor kinetic stability. The molecular docking study showed that the best ligand pose energy for the IOTH was −101.35 kcal/mol whereas the standard drug (acetohydroxamic acid) was −64.29 kcal/mol. The results demonstrated that the ligand–receptor complex remained stable during the MD simulations due to high binding affinity toBacillus pasteurii urease. The Lipinski Rule of Five was not violated in any way in the studied compound. This demonstrated that it is bioavailable. During clinical trials, the compound attrition rates would be lower, and the drug would have a better chance of being commercialized.

La industria panelera es una gran generadora de empleo, sin embargo, en los procesos de producción se presentan disfunciones que afectan la salud fisca y mental de los trabajadores. En el presente estudio se indagó por los factores que inciden en calidad de vida en el trabajo de las unidades agrícolas y agroindustriales que se dedican a la producción de panela teniendo en cuenta: Las condiciones de trabajo, el bienestar laboral y los efectos colaterales del trabajo. Se tomó una muestra de operarios pertenecientes a trapiches de la zona centro occidente de Colombia. Se encuestaron 108 personas. Se evidenció la evaluación positiva de algunas variables por parte de los operarios encuestados, sin embargo estas percepciones son subjetivas. Lo subjetivo del entorno de trabajo se relaciona con experiencias y creencias personales en el contexto rural donde viven los trabajadores y que se trasmiten de generación en generación. La calidad de vida en el trabajo en las unidades agrícolas estudiadas, desde el punto de vista subjetivo, es medianamente buena. objetivamente puede decirse que se requieren tomar medidas de mitigación frente a los altos niveles de precariedad en cada una de las variables evaluadas.

La decorina (DCN) es un proteoglicano presente en los músculos de bovinos y su cantidad puede afectar la formación de fibras de colágeno e influir en la calidad de la carne. Se carece de información sobre la cantidad de DCN presente en músculos de animales adultos con diferente condición corporal (CC) y su efecto con la calidad de la carne. El objetivo de este experimento fue relacionar la expresión del gen que codifica para DNC por medio de PCR en tiempo real y por localización inmunohistoquímica en tejido de bovinos Holstein con diferente CC y su posible efecto en la textura de la carne. Se utilizaron 20 vacas de desecho Holstein de diferentes orígenes, sistemas de producción y con cinco CC (CC-1, emaciado, CC- 2, delgado, CC-3, en peso, CC-4, gordo y CC-5, obeso) de un rastro TIF. Se tomaron muestras de tejido del músculo Longissimus dorsi (LD) de entre la 7a y 12a costilla de cada canal, las cuales se procesaron para la expresión del gen de DCN por PCR- RT y por localización inmunohistoquímica. Los datos del ARNm se ajustaron con un procedimiento GLM. La CC-1 y CC-2 presentaron valores de expresión bajos de ARNm, por el contrario, la CC-3, CC-4 y CC-5 presentaron valores altos. Lo anterior coincidió con lo observado en las micrografías donde se presenta una mayor intensidad de la inmunofluorescencia en las CC mayores (3 a 5), donde CC-5 presentó una franja de fluorescencia más gruesa, reflejando una mayor expresión de DCN. Los cambios en la expresión de la DNC aumentan cuando mejora la condición corporal de las vacas Holstein de manera lineal positiva.
La resurrección de los artistas a través de las nuevas tecnologías. Cuestiones jurídico-económicas en torno al derecho de imagen

Published: November 2023

Las cuestiones relativas a las propiedades especiales en cuestión de los derechos de carácter patrimonial y de los derechos de carácter moral en cuanto a sus alcances, han resultado siempre ambiguos y llenos de lagunas, la razón no es por culpa del legislador sino más bien que en virtud de la materia que se trata, que esta tan ligada a la tecnología, existen y, mucho nos tememos, existirán siempre lagunas, puesto que no somos capaces de llegar a predecir o ver el futuro, el cómo afectaran las conductas de los individuos y ni mucho menos ver los efectos que esto traerán en las nuevas creaciones, esquemas de negocios, contratos y límites del uso de cuestiones tan puntuales, tal y como se tratara a lo largo del presente estudio, la imagen de las personas que hubiesen fallecido. La cuestión de fondo que se pretende abordar es el auténtico derecho que pueden esgrimir, por un lado, parientes, por el otro lado contratos de carácter privado, compañías tanto de cine como de música (y ¿por qué no? otro tipo de empresas que usen la imagen de las personas para promocionarse) que pudieran considerar la comprar la “imagen” y hacer uso de ella, es decir revivir para efectos de publicidad a los artistas ya fallecidos, ¿deben de existir límites para esto? Si es así, ¿de qué tipo? ¿acaso la larga búsqueda de la riqueza, de manera honesta, puede verse limitada por cuestiones de carácter moral o de buen gusto? Para poder llegar a tratar de responder esto, es necesario atacar las preguntas planteadas a través de los dos grandes sistemas de protección de las propiedades especiales, tal y como lo son el sistema Copyright y el sistema de protección de la propiedad intelectual centrado en el Tratado de Berna, tomando en consideración de que, si bien, ambos tienen una esencia similar, sus fines que persiguen como los medios que emplean y su filosofía que subyace dentro de sus esquemas de protección son diametralmente diferentes, lo que hace que, será necesario partir de la cuestión, ¿a través de qué sistema, logro proteger (o explotar, según mi interés) la imagen de una persona ya fallecida?¿cómo puedo legitimar esta pretensión?
Configuración política y desempeño legislativo en la Cámara de Diputados con mayorías legislativas. El caso de la legislatura LXIV en México
Authors: Patrón Sánchez Fernando , González Medrano Gerardo
Published: November 2023

La elección federal en 2018 produjo cambios importantes en la representación política en México. Por más de veinte años ningún partido político contó con mayorías absolutas para aprobar legislación en el congreso. El regreso de mayorías amplias legislativas por un partido y su coalición gobernante sugiere un cambio en la lógica de la toma de decisiones legislativas. El artículo propone un análisis sobre los cambios ocurridos en la conformación política en la cámara de diputados durante la LXIV legislatura (2018-2021), sus implicaciones y la revisión sobre la producción legislativa. Presentamos datos sobre los cambios en la representación partidista, las diferencias con legislaturas anteriores ylas variaciones en las fracciones parlamentarias. De la misma manera, realizamos un análisis sobre la aprobación de iniciativas legislativas estableciendo diferencias con la legislatura LXII (2012-2015). Concluimos que, aunque se presenta un nuevo contexto con mayorías legislativas, las variacionesen la producción legislativa no son sustanciales.

Este artículo evalúa la relación entre el miedo al delito y las demandas por castigos más severos en contra de los acusados de actividad delictiva. Consideramos dos tipos de miedo al delito: 1) el miedo a los asaltos y robos; y 2) el temor al asesinato. Lo que caracteriza al miedo al delito es el sentimiento de vulnerabilidad en los ciudadanos por ser incapaces de protegerse a sí mismos.
Gestión municipal y modelo econométrico de ingresos municipal: Estado de México 2020
Authors: Villalobos López Jos Antonio
Published: November 2023

Para optimizar los procesos de gestión administrativa en los municipios se requiere contar con mayor capacitación de los funcionarios para que, con ello, puedan redistribuir los recursos de manera más eficiente. El modelo de ingresos municipales para el Estado de México en 2020 arrojó: 1) Las variables población y valor catastral inmobiliario resultaron determinantes para explicar los ingresos públicos totales —siguiendo en significancia el PIB municipal; 2) Valor catastral explica con alta significancia los montos recaudados de ingresos propios y de impuestos municipales mexiquenses, con ello, al tener mayor valor las propiedades catastrales, resultaría en incrementos de ingresos propios e impuestos —mientras que la variable población explica, en sentido inverso, esas dos figuras, derivando en que, ante aumentos de población, se generarían disminuciones en ingresos propios e impuestos; 3) No se presenta pereza fiscal ya que los recursos obtenidos por participaciones federales no desincentivan el cobro de las contribuciones locales.
Producción inmobiliaria comercial y gestión urbano territorial en el espacio periurbano sur del Área Metropolitana de Guadalajara
Authors: Rodríguez Rodríguez Jesús , Leal Arriaga Tulia
Published: November 2023

En el contexto de la reestructuración urbana del entorno periurbano, la producción inmobiliaria de tipo comercial y servicios muestran una tendencia en la elección de dicho territorio. De tal manera que, el centro comercial conlleva a una expresión de fragmentación urbana debido a la actividad de consumo que se realiza en el interior y la nula relación socio espacial con el contexto en que se ubica. En el caso del Área Metropolitana de Guadalajara se analiza la transformación urbana a partir de la instalación de la construcción de numerosos centros comerciales en el periurbano sur. El presente trabajo discute el fenómeno de la gestión de los instrumentos de planeación urbana, mismo que puede ser un precedente para establecer políticas urbanas específicas en territorios periurbanos.

Published: November 2023

The maximum velocity achieved during sprinting is a crucial aspect in various sports. Therefore, practitioners use various devices, such as laser or radar guns, timing gates (TG), and global positioning systems (GPS), to assess sprint performance. Although high-speed cameras are considered the most accurate equipment for assessing maximum velocity (V
max), TG are more commonly used because of their practicality and affordability. Recently, GPS technology has gained attention from the sport science community, primarily because of its applied characteristics, enabling “in situ” data exploration. However, there is currently no consensus on the validity, reliability, and sensitivity of GPS in field-based team sports not only for measuring V
max but also for tracking potential changes in sprint performance. We thoroughly examined the existing literature on the validity, reliability, and sensitivity of GPS technology for measuring V
max, with a specific emphasis on its application in team sports. Furthermore, we offer a comprehensive discussion on the capability of these devices to assess potential variations in V
max. By synthesizing current research findings, this narrative review sheds light on the strengths and limitations of GPS devices for assessing V
max in field-based team sport athletes.
Flexible Positions
Authors: Neumann David J.
Published: November 2023

Donald Walters was an ideal candidate to lead an eclectic transnational religious movement rooted in Hinduism that has survived for more than fifty years by balancing core commitments with flexibility on less central matters. He read Autobiography of a Yogi in 1948 and was mentored by its author, Paramahansa Yogananda, at Self-Realization Fellowship (SRF) in Southern California. Walters took his monastic vows in 1955 to become Swami Kriyananda. After leaving SRF, he decided to start Ananda, a cooperative living community northeast of Sacramento, in 1968. While similar to other hippie communes in its Eastern spirituality and sense of experimentation, it was unusual in rejecting drugs and embracing Jesus Christ. Despite hurdles, the community began to grow by the early 1980s. Like its principled-pragmatic organization, Ananda’s spiritual identity likewise combined a firm core and some flexibility in beliefs and practices. Its practices are drawn directly from those taught by Yogananda, including its syncretistic beliefs rooted in Hindu cosmology but shaped by fascination with Jesus Christ. Ananda eventually grew from a small California community into a global movement, establishing footholds in both India and Italy. Since the mid-1990s, the community has faced several challenges, including lawsuits and the death of Kriyananda. But his passing was an opportunity as well as a crisis. Following their mentor’s example of balancing core firmness with flexibility, recent leaders have ensured that Ananda will continue as a rural Northern California model of life and community, as well as a global spiritual enterprise centered on Kriya Yoga.

This study demonstrated a rapid method of producing PtPd via chemical reduction by varying metal composition and types of capping agents. The effect of different compositions between the two-metal precursor, Pt and Pd, is invested by tuning at various volume ratios of 3:1, 1:3, and 1:1 and comparing them with their single counterparts. The FESEM results show that all prepared samples exhibit nanosponges structure. PtPd of 1:1 ratio has the highest ECSA of 14.25 m2 /g, while PtPd with PVP exhibits a high ECSA value of 692.7 m2 /g compared to those without capping agent (287.8 m2 /g), indicating large active sites, which increases its catalytic function.

How public libraries deliver value online
Authors: Nielsen Mare Lundsfryd , Lensch Marie Cecilie , Frandsen Tove Faber
Published: November 2023

Purpose. The development and usage of digital library services have accelerated. Many libraries have expanded their digital services in response to the COVID-19 pandemic. The physical locations were closed or operated with reduced capacity and libraries continued to provide services digitally. The physical locations of many libraries have reopened but the development of digital services persists. Most libraries offer a wide variety of services digitally and many libraries are expanding their digital services. It is, therefore, relevant to explore how librarians perceive the digital public library services offered at their institutions and how the digital services supplement or replace services in the physical library.
Approach/methodology/design. This study presents the findings of an interview-based study with five librarians from different public libraries across Denmark.
Findings. The findings show that librarians perceive the physical and digital services as means to the same end while carefully considering the content, target audience and platform when offering services to their users. They see the digital services as a critical aspect of the raison d’etre of the library and means to attract new users.
Research limitations. It is important to note that this study is based on a small sample.
Practical implications. The implications for digital public library services are discussed and recommendations based on this study are considered.
Originality/value. While many studies have explored librarians’ perceptions of the value of public libraries, this study focuses on librarians’ perception of the value of digital libraries and how these services supplement or replace the physical library.

Non-industrial sugarcane production sector in Malawi is under-researched and under-developed with limited support. This study used a value chain approach to map the non-industrial sugarcane value chain in Zombwe Extension Planning Area in North Mzimba, Malawi to identify key actors, relationships and constraints in the chain. Multi-staged sampling technique was used to sample the study respondents and a structured questionnaire was used to collect data from 153 non-industrial sugarcane value chain actors. Qualitative data was collected through two focus group discussions (FGD) and analysed using a value chain flow chart. Descriptive statistics and functional and regression analysis were used to analyse the data. Results indicated that production, selling and consumption are key processes in the non-industrial sugarcane value chain. The actors in the value chain were producers, retailers and consumers who participated in the two channels of the value chain. Both channels start with producers and end with domestic consumers. The results have shown that the major constraints of producers were access to credit and extension services while the major constraints of retailers were transportation, access to credit and price fluctuations. Age, education level, land accessibility and credit accessibility are significant determinants of non-industrial sugarcane production (yield). The study recommends that non-industrial sugarcane producers and retailers be supported to access credit available through the government and other financial institutions. We recommend that extension services should include producers to improve the non-industrial sugarcane value chain. The paper will help policymakers and decision-makers identify potential areas for intervention towards the commercialisation of the non-industrial sugarcane value chain.

Digitally oriented companies with the primary business process of making digital products are greatly influenced by customer satisfaction. Customer satisfaction can be used as an indicator of the success of a product or service. If customer expectations are met, the satisfaction level will also be high. However, if their expectations are not met, this can have a fatal impact on the company. There are usually two different types of customers: internal and external. This study aims to measure inner customer satisfaction to ensure that the digital products being marketed have received support internally before hoping to get an excellent external response. As for digital product objects in this study, they are divided into several categories, namely wholesale, agriculture, fishery, and poultry, education, healthcare, productivity, utilities, e-commerce, and finance.
