Electric Vehicle Fleets: Scalable Route and Recharge Scheduling Through Column Generation
Authors: Parmentier Axel , Martinelli Rafael , Vidal Thibaut
Published: March 2023

The rise of battery-powered vehicles has led to many new technical and methodological hurdles. Among these, the efficient planning of an electric fleet to fulfill passenger transportation requests still represents a major challenge. This is because of the specific constraints of electric vehicles, bound by their battery autonomy and necessity of recharge planning, and the large scale of the operations, which challenges existing optimization algorithms. The purpose of this paper is to introduce a scalable column generation approach for routing and scheduling in this context. Our algorithm relies on four main ingredients: (i) a multigraph reformulation of the problem based on a characterization of nondominated charging arcs, (ii) an efficient bidirectional pricing algorithm using tight backward bounds, (iii) sparsification approaches permitting to decrease the size of the subjacent graphs dramatically, and (iv) a diving heuristic, which locates near-optimal solutions in a fraction of the time needed for a complete branch-and-price. Through extensive computational experiments, we demonstrate that our approach significantly outperforms previous algorithms for this setting, leading to accurate solutions for problems counting several hundreds of requests.

KÜLTÜR TURİZMİ PAZARLAMASINDA ÖRNEK İL İNCELEMESİ: ŞANLIURFA ÖRNEĞİ
Authors: KIZIL EROL Kader
Published: March 2023

Turizm, hem birçok sektöre kaynak oluşturan hem de birçok sektörden beslenen hizmet ağırlıklı bir sektör durumundadır. Üretilen her mal ve hizmetin talep bulmasının mümkün olmadığı, tüketicilerin artık çok daha seçici ve müşkülpesent oldukları günümüz toplumunda, ancak tüketicilerin ihtiyaç ve beklentilerini karşılayan ürün ve hizmetler rağbet görmektedir. Dolayısıyla, turistin ihtiyaçlarını karşılayacak mal ve hizmetlerin üretilmesi, tanıtılması ve en etkin şekilde pazarlanması gerekmektedir. Sosyal ve ekonomik rekabetin şehirlere kadar indirgendiği günümüz dünyasında, turizm pazarlaması kavramı daha da önemli bir hale gelmiştir. Artık, turizm alanında ülkelerden ziyade doğru pazarlama stratejileri kullanarak, şehirler rekabet gücünü arttırarak ön plana çıkmaya çalışmaktadır. Çünkü bir şehrin iyi tanınması ve etkin pazarlanabilmesi, daha çok fiziki ve beşeri sermaye çekebilmesi demektir. Bu da, ekonomik ve sosyal gelişmenin artması anlamına gelir. Bu çalışmada, turizm pazarlaması kavramı üzerinde durularak, şehrin markalaşmasında pazarlamanın önemine dikkat çekilmesi amaçlanmaktadır. Bu bağlamda, inanç turizmi açısından olduğu kadar tarihi çarşıları, müzeleri, kendine özgü zengin mutfağı ile kültür ve gastronomi turizmi alanlarında da çok önemli bir destinasyon olan Şanlıurfa, şehir pazarlaması açısından örneklenerek, şehrin turizm potansiyeli tanıtılmaya çalışılmıştır. Ayrıca, çalışmanın Şanlıurfa’nın tarihi ve kültürel değerlerine dikkat çeken bölümüyle bölge turizmine katkı sağlayacağı da düşünülmektedir.

Authors: Anitha P Anitha P , Begum T. Nargis , Kumar R Senthil
Published: March 2023

This study aimed to evaluate in vitro free radical scavenging activity and in vitro anti-diabetic properties of extracts from the sprout of Borassus fabellifier. Antioxidant activity was performed using DPPH, ABTS, FRAP, SO, and NO inhibition methods. The enzymes (α-amylase and α- Glucosidase inhibitory activities were investigated. Moreover, glucose adsorption and diffusion properties were also studied to confirm the potential effect of the sprout of B. fabellifier as an anti-diabetic drug. The ethanolic extracts of B. flabellifer exhibited high antioxidant activity towards DPPH, ABTS, FRAP, SO, and NO. However, the ethanolic extracts possessed the strongest inhibitory effect towards α-amylase and α-Glucosidase. The ethanolic extract showed excellent anti-diabetic activity when we examined using glucose adsorption and Glucose diffusion methods. This study suggested that the extracts from Borassus fabellifier sprout may act as a potential medicinal plant to treat diabetic complications.

Background

Loneliness is associated with many mental health conditions, as both a potential causal and an exacerbating factor. Richer evidence about how people with mental health problems experience loneliness, and about what makes it more or less severe, is needed to underpin research on strategies to help address loneliness.

Methods

Our aim was to explore experiences of loneliness, as well as what helps address it, among a diverse sample of adults living with mental health problems in the UK. We recruited purposively via online networks and community organisations, with most interviews conducted during the COVID-19 pandemic. Qualitative semi-structured interviews were conducted with 59 consenting participants face-to-face, by video call or telephone. Researchers with relevant lived experience were involved at all stages, including design, data collection, analysis and writing up of results.

Findings

Analysis led to identification of four overarching themes: 1. What the word “lonely” meant to participants, 2. Connections between loneliness and mental health, 3. Contributory factors to continuing loneliness, 4. Ways of reducing loneliness. Central aspects of loneliness were lack of meaningful connections with others and lack of a sense of belonging to valued groups and communities. Some drivers of loneliness, such as losses and transitions, were universal, but specific links were also made between living with mental health problems and being lonely. These included direct effects of mental health symptoms, the need to withdraw to cope with mental health problems, and impacts of stigma and poverty.

Conclusions

The multiplicity of contributors to loneliness that we identified, and of potential strategies for reducing it, suggest that a variety of approaches are relevant to reducing loneliness among people with mental health problems, including peer support and supported self-help, psychological and social interventions, and strategies to facilitate change at community and societal levels. The views and experiences of adults living with mental health problems are a rich source for understanding why loneliness is frequent in this context and what may address it. Co-produced approaches to developing and testing approaches to loneliness interventions can draw on this experiential knowledge.
Comparative efficacy and acceptability of interventions for insomnia in breast cancer patients: A protocol for systematic review and network meta-analysis
Authors: Li Zhifan , Wang Qian , Xu Junxia , Song Qihua , Ling Xiaoling , Gao Ya , Lei Junqiang
Published: March 2023

Background

Symptoms of insomnia are highly prevalent in patients with breast cancer. There are a large number of pharmacological and non-pharmacological interventions that can be used for the management of insomnia in breast cancer patients; however, their comparative effectiveness and acceptability remain uncertain. This review aims to evaluate the efficacy and acceptability of different interventions for insomnia in breast cancer patients using a Bayesian network meta-analysis (NMA).

Methods

We will perform a comprehensive literature search in PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and PsycINFO from inception to November 2022. We will include randomized controlled trials (RCTs) that compared the effects of different interventions on the management of insomnia in breast cancer patients. We will assess the risk of bias assessment using a modified Cochrane instrument. We will conduct a Bayesian random-effects framework NMA to estimate relative effects of interventional procedures. We will use Grading of Recommendations Assessment, Development and Evaluation to rate the certainty of evidence.

Discussion

To our knowledge, this will be the first systematic review and network meta-analysis to compare the effectiveness and acceptability of all currently available interventions for insomnia in patients with breast cancer. The results of our review will help provide more evidence for the treatment of insomnia in breast cancer patients.

The eroticization of Tibetan monks in shōnen-ai and yaoi manga
Authors: Christopher Stephen , Laumonier Gabrielle
Published: March 2023

Men have historically dominated the artistic production of cultural exotifications. This article flips the script by analysing how two prominent female Japanese manga artists – Kuranishi and Shinsan Nameko – erotically illustrate Tibetan men, specifically Tibetan Buddhist monks. Through textual analysis and fieldwork conducted between 2019 and 2021, we show how their manga depictions of Tibetan young men, in particular monks, tend towards eroticization and sexual innuendo. This discursive and aesthetic trend in manga parallels ethnographic data on how Japanese women – facing unprecedented social precarity, seeking spiritual healing and self-transformation and desiring alternate masculinities – look elsewhere, outside of Japan and the perceived inadequacies of Japanese masculinities. We explore how liberative erotics, especially homoeroticism and love between boys, fuses with Buddhist and alternative spiritualities in yaoi and shōnen-ai genres and gestures towards a changing landscape of female desire.

Eficiência na atenção à saúde no SUS
Authors: Araujo Moisés , Mendes Áquilas
Published: March 2023

Observa-se que, na literatura sobre os sistemas nacionais de saúde, a discussão sobre a noção de eficiência, de forma geral, está muito mais associada à relação custo-benefício e aos resultados apurados, especialmente restrita ao campo de uma unidade produtiva. O conceito de eficiência é abordado de forma extensa na literatura e apresenta distintas concepções, a depender do campo de estudo e da natureza do pensamento econômico e social. Nessa perspectiva, este artigo objetivou analisar como a questão da eficiência relacionada à atenção à saúde no Sistema Único de Saúde – SUS tem sido discutida na literatura científica. Realizou-se uma revisão sistemática da literatura, tendo como pergunta de pesquisa: “O que a literatura científica apresenta sobre a questão da eficiência com relação à atenção à saúde no SUS?”, utilizando o portal BVS, com busca de descritores realizada por meio do DeCS da própria plataforma. Para tanto, a estratégia de busca com base na pergunta de pesquisa foi dividida em três polos: fenômeno, contexto e população, sendo eles: o fenômeno “eficiência”, o contexto “sistema único de saúde” e a população “atenção à saúde”. Foram considerados pelo protocolo PRISMA 15 artigos. Foram identificados alguns aspectos nesses artigos: em primeiro lugar, pode-se perceber que o conceito e a concepção da eficiência divergem conforme o pensamento econômico e o setor onde se discute, se público ou privado; em segundo, a questão da eficiência tende a mudar conforme o objeto de estudo. Dentro do setor público, por exemplo, utiliza-se normalmente a eficiência produtiva para analisar hospitais, e aborda-se a eficiência alocativa para discutir distribuição de recursos. Em terceiro lugar, percebe-se que o setor público de saúde é um sistema altamente eficiente, diante do quadro de subfinanciamento de que dispõe, o que contraria os ditames do Banco Mundial sobre a temática da eficiência.

Published: March 2023

O final do ano de 2019 foi marcado pelo surgimento e ascensão de mais um dos agentes responsáveis por uma pandemia na história da humanidade, o vírus SARS-CoV-2, causador da COVID-19, doença que tem relação com o ambiente. Assim, o objetivo do presente estudo foi buscar uma associação entre os fatores ambientais referentes aos ecossistemas e à higiene e a COVID-19. A metodologia consistiu em um levantamento bibliográfico nas bases de dados PubMed, MedLine, Scielo e Google Acadêmico, resultando, após aplicação dos critérios de exclusão, em 7 artigos para realização de uma revisão integrativa. Os resultados obtidos demonstraram que as condições de vida em comunidades pobres e aglomeradas, a qualidade da água e a coleta e tratamento de esgoto são fatores relevantes no processo de transmissão da doença, porém nenhum artigo tratou especificamente sobre os aspectos ambientais gerais relacionados ao ecossistema. Dessa forma, conclui-se que é necessário o maior destaque das temáticas que envolvem a relação do homem com o ambiente nas discussões sobre a COVID-19 e as demais doenças infecciosas.
Challenges and Trends of the logistics 4.0
Authors: Malagon-Suarez Camila Patricia , Orjuela-Castro Javier Arturo
Published: March 2023

Context:  Owing to the technological breakthrough in the worldwide productive systems, generated by the 4.0 revolution, it is compulsory to make sweeping changes to logistics both nationally and internationally to allow supply chains to enhance their performance and their response time. Hence, the concept of Logistics 4.0 was born. Although many developed countries have implemented the principles of Logistics 4.0, there is still a breach in its study and application worldwide. This article explores the challenges and tendencies in the implementation of Logistics 4.0.
Method: Articles published from 2015 to 2021 in the databases of Scopus, Science Direct, Taylor and Francis and Google Scholar, were analyzed by a systematic literature review. The explored publications were found using the search terms: (("logistics 4.0") OR ("supply chain 4.0") OR ("industry 4.0" AND ("logistics" OR "supply chain"))) and ((“blockchain” OR “IoT” OR “Cyber Physical Systems” OR “Big Data”) AND “logistics”) in title, abstract and keywords.
Results: It was proposed a conceptualization of Logistics 4.0 including definition, objectives, characteristics, and most representative technologies in its implementation. Likewise, the main challenges and trends that industries could face in the implementation of Logistics 4.0 within logistics systems, and supply chains were identified.
Conclusions: Logistics 4.0 is a novelty term that has aroused the interest of researchers, governments, and companies worldwide, due to its promising benefits in reducing response times and increasing flexibility and collaboration in supply chains. However, the lack of a common framework for its study and adoption has hindered its integration in companies and supply chains, specially in those located in developing countries, which must face technical, social, economic, and legal barriers for the implementation of logistics 4.0.

Authors: Palacios Nancy , Rodríguez Miguel
Published: March 2023

Si bien la educación para la paz es pertinente en cualquier lugar, en Colombia es necesaria y urgente, dados los altos niveles de violencia alcanzados en el país. El estudio plantea la necesidad de fortalecer el campo de educación para la paz con justicia social en la educación secundaria en Colombia, como una de las acciones que puede contribuir al principio de no repetición del conflicto armado. Se evaluaron 209 narrativas de estudiantes de secundaria de Bogotá sobre el acuerdo de paz; en cada narrativa se evaluó los principales componentes de su construcción y dos habilidades del campo de educación para la paz que se podrían articular con el campo de educación para el futuro, la toma de perspectivas y las propuestas de solución. Se utilizó una metodología cuantitativa que incluyó la realización de ejercicios estadísticos como: t-test, densidad de Kernels, chi-cuadrado, análisis de clúster y de correspondencias múltiples. Los resultados hicieron evidente la necesidad de implementar pedagogías como las que se han planteado desde la educación para la paz orientada a que los estudiantes se preparen para los cambios que requiere el país del posconflicto y para liderar las acciones que les permita ser protagonista de dichos cambios desde sus comunidades.
Neurofilament light chain as neuronal injury marker – what is needed to facilitate implementation in clinical laboratory practice?
Authors: Arslan Burak , Zetterberg Henrik
Published: March 2023

Neurobiomarkers have attracted significant attention over the last ten years. One promising biomarker is the neurofilament light chain protein (NfL). Since the introduction of ultrasensitive assays, NfL has been developed into a widely used axonal damage marker of relevance to the diagnosis, prognostication, follow-up, and treatment monitoring of a range of neurological disorders, including multiple sclerosis, amyotrophic lateral sclerosis, and Alzheimer’s disease. The marker is increasingly used clinically, as well as in clinical trials. Even if we have validated precise, sensitive, and specific assays for NfL quantification in both cerebrospinal fluid and blood, there are analytical, as well as pre- and post-analytical aspects of the total NfL testing process, including biomarker interpretation, to consider. Although the biomarker is already in use in specialised clinical laboratory settings, a more general use requires some further work. In this review, we provide brief basic information and opinions on NfL as a biomarker of axonal injury in neurological diseases and pinpoint additional work needed to facilitate biomarker implementation in clinical practice.
Comparative assessment of high gain boost converters for renewable energy sources and electrical vehicle applications
Authors: Veerabhadra J. , Nagaraja Rao Sulake
Published: March 2023

Due to greenhouse gas emissions and the energy crisis, the conventional way of generation of electricity using fossil fuels is being substituted with Renewable Energy Sources (RES) like solar photovoltaics (SPV), fuel cells, wind, etc. The voltage produced by RES is very small in magnitude; therefore, the choice of DC–DC converter is critical for regulating and improving the output of RES to its maximum level. To meet the power requirement for the utility grid and electric vehicles (EV), the voltage must be enhanced. So far, various types of high-gain DC–DC boost converter (HG-BC) topologies have been suggested. An overview of HG-BC topologies for RES and EV applications is presented in this paper, which provides a unique, extensive, perceptive, and comparative analysis of HG-BC topologies. The mathematical modeling and operating principles of each converter topology have been analyzed and discussed. The boost factor (B) and component count for various HG-BC are thoroughly compared for a 0.5 duty cycle using the MATLAB/Simulink tool.
Developing imagery ability in esport athletes using layered stimulus response training
Authors: Cumming Jennifer , Quinton Mary L.
Published: March 2023

For esport athletes to effectively use imagery and experience its many benefits, they must develop a collection of skills referred to as imagery ability. Layered stimulus response training (LSRT) is an evidence-based technique informed by bioinformational theory to improve how easily someone can form rich and vivid images that more closely approximate the real-life situation. In turn, having a better ability to generate and control clear and vivid images is associated with better performance and optimal mental and emotional states. The aim of this paper is to explain how sport psychologists can guide esport athletes through cycles of LSRT, which involves imaging, evaluating, reflecting, and then developing images in progressive layers of different stimulus, response, and meaning propositions. Aids to image generation and other variations of LSRT as well as future research opportunities for applying LSRT to esport are also discussed.
Alteration of physicochemical properties of tap water passing through different intensities of magnetic field
Authors: Jawad Saba I. , Karkush Mahdi , Kaliakin Victor N.
Published: March 2023

This study reports the effect of the magnetization process on the chemical and electrical properties of tap water (TW). Also, a step in the direction of gaining a better understanding of the influence of magnetizing technique on the physicochemical properties of water exposed to several intensities of magnetic field (MF). The TW sample used in this study passed through four intensities of the MF (2,000, 4,000, 6,000, and 8,000 G) under the same conditions of temperature and pressure. Magnetized water was tested and evaluated for physical and chemical qualities after being cycled through a magnetization device for 6 h. Following the increase in the intensities of the MF, the alteration in water properties has been depicted. The results showed increase in the pH value, electrical conductivity, and some of the chemical properties. The optimum change in the properties of water were obtained when the intensity of MF reached 8,000 G. However, to assess the obtained modification of water quality from the magnetization process, the results are compared with the guideline standards of the World Health Organization. To reduce the treatment costs and increase the long-term viability of the process, the study findings suggested a strategy of water magnetization as an effective treatment technology with reduction in energy and material usage (green technology).
Scare quotes as deontic modals
Authors: Wiślicki Jan
Published: March 2023

The aim of this article is to propose a formal semantic account of scare quotation (SQ). I present data showing that SQ, though flexible, is subject to regular and so far largely unnoticed limitations following from the infelicitous use of irony as well as the division between at-issue and not-at-issue content parts. While these effects can hardly be accounted for by assuming that the ironic aspect of SQ involves negation, they are in harmony with basic properties of deontic modality. I formulate a deontic modal account of SQ which not only predicts the complex behaviour of SQ, but also sheds much new light on the formal nature of irony.
Effect of alloying elements on mechanical behaviour of Cu-Zn-Sn bronzes
Authors: Teker Tanju , Yılmaz S. Osman , Bulus Ercan
Published: March 2023

The effect of Fe, P and Mn on microstructure and fatigue properties of CuZnSn bronzes investigated with optical microscopy and scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction, hardness, tensile and fatigue tests. The addition of Fe, Mn and P to Cu-Zn-Sn bronzes formed Cu31Sn8, Cu6Sn5, ZnSn2, PbSnS2, ZnS, Cu2S, FeZn9 and FeZn21 phases. These phases were deposited between the dendrite arms and were dissolved in the matrix in small amounts. Especially, these precipitated phases were effective in fatigue properties. The formation of Cu-Sn, Cu-Zn and Zn-Sn intermetallic phases emitted due to the addition of Fe, Mn and P increased the fatigue strength. The spread of ferrous phases caused an increase in mechanical properties. The beneficial effect of P addition on the fatigue life far surpassed that of Mn and Fe additives.
Berufliche Bildung als Innovationstreiber: Ein lange vernachlässigtes Forschungsfeld
Authors: Backes-Gellner Uschi , Lehnert Patrick
Published: March 2023

Länder mit einer starken Betonung der beruflichen Bildung in ihren Bildungs- und Innovationssystemen, beispielsweise Deutschland und die Schweiz, zählen seit Jahren zu den innovativsten der Welt. Gleichzeitig konstatiert internationale Innovationsforschung, dass ein hoher Akademisierungsgrad (und damit gerade nicht die berufliche Bildung) für starke Innovationsleistungen unabdinglich ist. Wie lässt sich dieser Widerspruch erklären? In diesem Überblicksartikel zeigen Uschi Backes-Gellner und Patrick Lehnert anhand einer Aufarbeitung neuer Forschungserkenntnisse, warum die deutschsprachigen Länder nicht trotz, sondern gerade auch wegen ihres Berufsbildungssystems hochinnovativ sind. Zu den erforderlichen institutionellen Rahmenbedingungen für diesen Effekt gehören dabei die zukunftsorientierte Gestaltung und Aktualisierung von Berufsausbildungscurricula, die Vermittlung von breiten beruflichen (statt engen betriebsspezifischen) Kompetenzen in dualen Berufsausbildungsprogrammen, ein durchlässiges Bildungssystem mit attraktiven Karrierepfaden sowie eine Verknüpfung von tertiärer beruflicher Bildung und angewandter Forschung.

Cadmium Sulphide being an important II-VI compound semiconductor has wide applications in various optoelectronic and biolabeling devices. In the present work, undoped and Ni (2%, 4%, 6% and 8%) doped CdS nanoparticles were synthesized in aqueous medium by microwave assisted solvo thermal method using cadmium acetate, nickel chloride and sodium sulphide as precursors. The effect of Ni doping on the Structural, Morphological and Optical Properties of CdS nanoparticles have been studied by X- ray diffraction, SEM, FTIR, PL and UV-Visible spectroscopy. The crystal structure and morphology of the as synthesized nanoparticles have been investigated by X- ray diffraction and scanning electron microscopy (SEM). The XRD results revealed the crystalline nature of the nanoparticles. The average grain size of the nanoparticles was estimated using Scherrer equation which was found to be in the range of 4.2 - 6 nm. The FTIR spectra were also recorded to identify the presence of various functional groups in the synthesized CdS nanoparticles. For the estimation of the optical energy band gap of as synthesized nanoparticles, absorption spectra were recorded using UV- Visible spectrophotometer. The result of UV-Visible spectra revealed the increment of energy band gap in CdS nanoparticles on increasing the concentration of Ni.

Thermophotovoltaic (TPV) energy conversion systems convert solar energy into electricity via thermally radiated photons at tailored wavelengths to increase energy conversion efficiency. In this study, we report the design and analysis of a TPV system with one-dimensional photonic crystals (1DPCs) filter using thermal electrical model that includes the thermal coupling between the emitter/filter (PhCs)/PV cell. The performance of the proposed structure, one-dimensional photonic crystals (TiO2/SiO2) 6 with P periods of Titanium Dioxide (TiO2)and Silicon Dioxide (SiO2) of thermophotovoltaic system, has been studied by Mbakop et al [1] and Banerjee et al[2]. The temperature distribution and electrical power output of TPV cell are calculated at a heat varying from 1000 K to 1600 K using parametric solver at a regular interval of 25 K. Furthermore, voltaic efficiency distribution in a concentrating thermal photovoltaic system is presented.

Optical and electrical properties is studied for (ZnO + 01MnO2 + 0.4Co3O4 + xBi2O3 + yTiO2), where (x=0.6,1 & y=0.6,1mol%) using Photopyroelectric (PPE) spectroscopy that is nondestructive tool, incident light wavelength, kept in the range 300 nm–800 nm modulated at 10 Hz. The main objective of this study is to discuss the PPE spectrum based on doping level and sintering temperature. Optical energy band-gap (Eg) for x=0.6 and 1 mol% is 2.15 eV and 2.17 eV, respectively, which is calculated from the plot (ρhυ) 2 versus hυ at 1 hour sintering time. Steepness factor ‘σA’ and ‘σB’, is discussed with reference to the variation of Eg and sintering time which describe the slope of exponential+l optical absorption. Other characterization for the ceramic were studied using XRD, EDAX and SEM. The relative density decreased with the increase of sintering time and doping level. It was investigated that the grain size increased with the increase of sintering time.

El territorio en la literatura italiana: notas sobre representación y significación histórico-cultural del espacio geográfico en la literatura italiana desde Dante a Pirandello.
Authors: Panico Francesco , Pace Riccardo
Published: March 2023

El estudio acerca del tratamiento del paisaje y el territorio en la literatura italiana, como en cualquier otro contexto de esa naturaleza, se torna en un modo para explorar los horizontes culturales que han sido influenciados (y a su vez han influido) por las obras narrativas y poéticas de esa tradición. A través de las poéticas de los principales autores italianos (de quienes se han tomado como ejemplos algunos pasos de sus obras más conocidas), a partir de Dante hasta llegar a Pirandello, pasando por Ariosto, Leopardi Manzoni y Verga, se dibuja un recorrido temático sobre cuya trayectoria se dan cita, de manera difícilmente separable, el espacio y el tiempo, categorías culturales que la literatura ha modelado de diferentes formas.
El erotismo en las revistas de humor político: "Las Jais" de Francisco Umbral y "Señoras y Señores" de Juan Marsé
Authors: Cabrera Cobos Marta
Published: March 2023

Las revistas de humor político surgidas en los últimos años del franquismo y durante la democracia no permanecieron al margen del tímido erotismo que iba abriéndose paso en el país. Importantes escritores, como Francisco Umbral y Juan Marsé entre otros, firman artículos con su personal estilo no exentos de ironía que constituyen un importante testimonio de la sociedad de la época. La diversidad estilística de ambos autores no impide que compartan esa admiración por la mujer y el tono lírico, humorístico e incluso a veces, caricaturesco de sus descripciones.
El espacio de lo posible: Las tertulias literarias en "La noche que llegué al Café Gijón" de Francisco Umbral
Authors: Ripoll Sintes Blanca
Published: March 2023

El objetivo de este artículo radica en estudiar de forma sistemática a qué tertulias literaria asistió Francisco Umbral cuando se instaló en Madrid en 1960, a partir de la lectura atenta de La noche que llegué al Café Gijón (1977): la tertulia del Gijón, la del Ateneo, la del Café Teide, la de Chicote, etc. Se analizará cómo estas tertulias incidieron en la configuración de la voz literaria y del personaje público del escritor, a partir de la teoría de redes desarrollada por Espagne y Werner, y de la historia cultural de los intelectuales europeos de Martí Monterde.
El motivo literario como elemento fundamental para la literatura comparada
Authors: Orea Rojas Mari Carmen
Published: March 2023

En estas líneas se busca definir el motivo literario como un elemento fundamental para establecer relaciones y comparaciones entre textos literarios, debido al carácter migratorio del concepto. Se analizan las cuestiones epistémicas que sostienen a la noción de motivo literario, así como sus orígenes en los textos del formalismo ruso, partiendo de un elemento tomado del mundo de las artes y la música.  Por medio del concepto de motivo literario, se puede mostrar la relación existente, a partir de unidades temáticas, entre obras de diversos momentos históricos o de diferentes latitudes, en donde, sin embargo, existen ideas nucleares enlazando significativamente variados textos.
Los entresijos del sujeto deseante felisbertiano: Entre alusiones y representación del acto sexual
Authors: Gutiérrez Daniel Gustavo
Published: March 2023

La poética de Felisberto Hernández oscila entre lo fantástico y lo extraño, entre lo metafórico y lo alusivo. Su escritura manifiesta los pliegues de una subjetividad que gusta de ocultarse tras el gesto literario. Lo biográfico y lo imaginario van conformando la trama interna de un mundo narrado orientado siempre hacia la apertura textual. El presente trabajo intenta recorrer un tópico bastante presente en la narrativa felisbertiana, a saber, el tópico de la sexualidad. La mujer parecida a mí (1947) será el terreno textual donde indagar en una lectura en clave pornográfica de la obra articulándola con una reflexión sobre la relación entre literatura y representación del acto sexual.
Охорона громадського здоров'я як об'єкт державного управління. Державна політика у сфері боротьби з туберкульозом: світовий досвід
Authors: Бородін Євгеній , Моісеєва Любов
Published: March 2023

У статті розглянуто світовий досвід державної політики у сфері боротьби з туберкульозом. Підкреслено неузгодженість  проблеми громадського здоров’я в культурі суспільства. Показано, що істотним відображенням соціальної значущості здоров’я в його індивідуальних і соціальних планах є взаємозв’язок здоров’я з соціально-трудовими можливостями людини, з положенням окремих соціальних груп в структурі суспільного виробництва.

Обґрунтовано,    що у сучасному суспільстві розвиток   таких цінностей, як охорона здоров’я та збереження здоров’я, далеко не однаковий для різних груп і верств населення. Це значною мірою залежить від  положення індивідів і груп в тій чи іншій системі соціальної  нерівності.  Доведено, що здоров’я служить серйозною  основою для виявлення і самоідентифікації людей в системі соціальної нерівності і, отже, передумовою їх соціальних взаємодій, соціальної згуртованості або роз’єднаності, а крім того, істотним фактором соціально-психологічного клімату соціальних груп і суспільства взагалі.

На думку авторів, у разі пріоритетності громадського здоров’я в контексті його соціальної обумовленості на рівні населення і спільності якісно змінюється шкала відповідальності соціальних суб’єктів. При цьому державноуправлінський дискурс може ставити дуже актуальні завдання, серед яких: соціальні механізми вироблення політичних рішень у сфері громадського здоров’я, типологія і ефективність різних політичних систем – організацій, держав в плані збереження здоров’я населення, соціальна і політична відповідальність держави та провідних суб’єктів політичного життя за збереження, ефективну охорону здоров’я населення як фундаментального потенціалу соціальних груп, нації, країни в цілому, теоретична модель (концепція) та ефективність соціальної політики держави з точки зору взаємозв’язку окремих напрямів цієї політики (охорона здоров’я, соціальний захист населення, освіта тощо).
Забезпечення публічного управління закладами освіти в територіальних громадах
Authors: Даниленко Лідія , Ларіна Наталія
Published: March 2023

В умовах децентралізації влади в Україні пріоритетною постає діяльність представницьких органів влади на місцях – тих, що обираються громадянами держави у встановленому законом порядку і спрямовують свою діяльність  на реалізацію інтересів, потреб та цінностей всього суспільства і мешканців територіальної громади, зокрема.

Актуалізована увага на сучасних вимогах до публічного управління закладами освіти на місцевому рівні в умовах реалізації політики децентралізації владних повноважень в Україні, зокрема на питаннях: розвитку лідерства; стандартизації діяльності органів місцевої влади, що ґрунтується на міжнародних стандартах якості;  своєчасній  і доцільній трансформації вимог до діяльності посадових осіб місцевого самоврядування в умовах, зокрема пов’язаних із воєнним станом, що передбачають посилення міжмуніципального співробітництва громади.

Розглянуто європейську традицію публічного управління, що формується впродовж кількох десятиліть, щодо офіційного визнання сутності сучасного представницького лідерства як професійного служіння громаді, країні, державі.

З’ясовано, що в умовах децентралізації владних повноважень важливою є стандартизація діяльності органів місцевої влади, що обумовлена загальновизнаними стандартами якості, встановленими Міжнародною організацією зі стандартизації – ISO, які ґрунтуються на таких принципах управління якістю, як: орієнтація на замовника; лідерство; залучення працівників; процесний і системний підходи; постійне вдосконалення; прийняття рішень на підставі фактів; взаємовигідні стосунки з постачальниками.

Наголошено на необхідності забезпечення зміни вимог до діяльності публічних службовців України в умовах війни з рф, що передбачають  посилення відповідальності за порушення принципів моралі, Кодексу честі депутата, державного службовця, керівника.

Зазначено, що керівники установ і закладів освіти в територіальних громадах мають враховувати освітні інтереси і потреби мешканців, забезпечувати реалізацію принципу «служіння територіальній громаді», створювати умови для посилення міжмуніципального співробітництва громади.

Запропоновано органам місцевого самоврядування використовувати  зарубіжні моделі розвитку професійного потенціалу посадових осіб місцевого самоврядування зі сфери освіти.
Концептуальні засади реалізація державної політики формування національно-патріотичної свідомості та демократичних цінностей молоді в Україні
Authors: Бизов Сергій
Published: March 2023

Актуальність дослідження зумовлено тим, що ні Стратегія національної безпеки України «Безпека людини – безпека країни» (2020 р.), ні Стратегія національно-патріотичного виховання (2019 р.) не визначають комплексно засади й особливості формування національно-патріотичного виховання та впровадження демократичних цінностей в української молоді.

Виявлено, що причинами такої ситуації, що склалася, є відсутність цілісної концепції такого виховання. Акцентовано, що це негативно позначається на розвитку суспільства та нації в цілому. З урахуванням загальних положень публічного управління аргументовано, що саме концепція має передувати затвердженню відповідної стратегії. Інакше можна стикнутися з тим, з чим стикнулися сьогодні на вітчизняних теренах, що у межах обох надважливих стратегій не враховані ключові засади фундаментальної науки, що уможливило відірваність від неї управлінської практики. Установлено, що вона зважати на науково обґрунтовані форми та методи патріотичного виховання, що базуються на українських народних традиціях, найкращих здобутках національної та світової педагогіки та психології, і що важливо – публічного управління й адміністрування. Аргументовано, що саме воно покликано забезпечити впровадження міждисциплінарного підходу до забезпечення комплексного та концептуального формування національно-патріотичного виховання в Україні. Усе це засвідчило актуальність обраної тематики дослідження.

Мета статті полягає у визначенні концептуальних засад щодо реалізації державної політики формування національно-патріотичної свідомості та демократичних цінностей молоді в Україні.

Серед отриманих результатів – наукове обґрунтування ключових положень Концепції національно-патріотичного виховання молоді та формування в неї демократичних цінностей в Україні. До цих положень віднесено мету, завдання, принципи, напрямки реалізації державної політики у сфері формування національно-патріотичного виховання молоді та впровадження демократичних цінностей.
De lucem aspicio a la sombra neoliberal: la tercerización de servicios de limpieza en la Universidad de Costa Rica
Authors: Caamaño Morúa Carmen , Dinartes Bogantes Andrés
Published: March 2023

Introducción: La transformación de las universidades en corporaciones para el lucro ha llevado a que se utilice la tercerización como un medio para reducir costos.

Objetivos: Este artículo busca conocer la forma en que se construye la tercerización, entendida como un «tercer espacio» o «espacio en medio», por las personas trabajadoras contratadas por la empresa Servicio de Limpieza a su Medida S.A (SELIME) para brindar servicios de limpieza en la Universidad de Costa Rica (UCR). Asimismo, intenta describir cómo estas personas viven la precariedad laboral establecida mediante contratos, normativas y prácticas entre lo privado y lo público.

Método y técnica: La investigación se basa en observación participante, revisión de cinco actas del Consejo Universitario, en nueve entrevistas en profundidad con personas trabajadoras de limpieza, una entrevista con el personal de la Oficina de Servicios Contratados que giran alrededor de las categorías condiciones laborales y ambiente laboral; y otra con el equipo de trabajo formado por la Vicerrectoría de Administración, a cargo de analizar las políticas sobre tercerización en la UCR, la forma en que estas se han implementado y el procedimiento para aprobar las licitaciones.

Resultados: Se determina la manera en que una gestión bicéfala y ambigua estructura formas de precariedad que jerarquizan y vulneran los cuerpos de las personas que deben dedicarse a tareas de limpieza, esto al ocupar el escalón más bajo de una estructura normada pero arbitraria y hostil, especialmente en el contexto de la pandemia del Covid-19.
