Authors: Muta Kensuke , Okamoto Kazuhiro , Nakayama Hiroki , Wada Shuto , Nagaki Aiichiro
Published: May 2024

Organofluorine compounds have greatly benefited the pharmaceutical, agrochemical, and materials sectors. However, they are plagued by concerns associated with PFAS. Additionally, the widespread use of the trifluoromethyl group is facing imminent regulatory scrutiny. Defluorinative functionalization, which converts the trifluoromethyl to the difluoromethyl motifs, represents the most efficient synthetic strategy. However, general methods for robust C(sp3)–F bond transformations remain elusive due to challenges in selectivity and functional group tolerance. Here, we present a method for C(sp3)–F bond defluorinative functionalization of the trifluoromethyl group via difluoromethyl anion in flow. This new approach tames the reactive difluoromethyl anion, enabling diverse functional group transformations. Our methodology offers a versatile platform for drug and agrochemical discovery, overcoming the limitations associated with fluorinated motifs.

The implementation of nanocomposite materials as electrode layers represents a potential turning point for next-generation of solid oxide cells in order to reduce the use of critical raw materials. However, the substitution of bulk electrode materials by thin films is still under debate especially due to the uncertainty about their performance and stability under operando conditions, which restricts their use in real applications. In this work, we propose a multiphase nanocomposite characterized by a highly disordered microstructure and high cationic intermixing as a result from thin-film self-assembly of a perovskite-based mixed ionic-electronic conductor (lanthanum strontium cobaltite) and a fluorite-based pure ionic conductor (samarium-doped ceria) as an oxygen electrode for reversible solid oxide cells. Electrochemical characterization shows remarkable oxygen reduction reaction (fuel cell mode) and oxygen evolution activity (electrolysis mode) in comparison with state-of-the-art bulk electrodes, combined with outstanding long-term stability at operational temperatures of 700 ºC. The disordered nanostructure was implemented as a standalone oxygen electrode on commercial anode-supported cells, resulting in high electrical output in fuel cell and electrolysis mode for active layer thicknesses of only 200 nm (>95% decrease in critical raw materials with respect to conventional cathodes). The cell was operated for over 300 hours displaying excellent stability. Our findings unlock the hidden potential of advanced thin-film technologies for obtaining high-performance disordered electrodes based on nanocomposite self-assembly combining long durability and minimized use of critical raw materials.
Deciphering molecular embeddings with centered kernel alignment
Authors: Welsch Matthias , Hirte Steffen , Kirchmair Johannes
Published: May 2024

The creation of effective models is of utmost importance in various scientific and engineering domains. However, analyzing such models, especially nonlinear ones, poses significant challenges. In this context, centered kernel alignment (CKA) has emerged as a promising model analysis tool that assesses the independence between two embeddings. CKA's efficacy depends on the selection of a kernel that adequately captures the underlying properties of the compared models. We examine the properties of the linear and random forest (RF) kernel with respect to multilayer perceptrons (MLPs) and RFs to adapt the model analysis tool CKA to cheminformatics. Furthermore, we demonstrate the utility of CKA in cheminformatics in three case studies in which we (1) investigate why optimizing the radius of circular fingerprints beyond two bonds results in only minor changes in the performance of models, (2) analyze the dependence between physicochemical properties and the molecular representations induced by graph neural networks (GNNs) that use addition as readout operation, and (3) compare different graph readout operations in GNNs.
One-step Catalyst-Transfer Macrocyclization: Expanding the Chemical Space of Azaparacyclophanes
Authors: Ayuso-Carrillo Josue , Fina Federica , Galleposo El Czar , Ferreira Ruben , Mondal Pradip Kumar , Ward Benjamin D. , Bonifazi Davide
Published: May 2024

In this paper, we report on a one-step catalyst-transfer macrocyclization (CTM) reaction, based on the Pd-catalyzed Buchwald-Hartwig cross-coupling reaction, selectively affording only cyclic structures. This route offers a versatile and efficient approach to synthesize aza[1n]paracyclophanes (APCs) featuring diverse functionalities and lumens. The method operates at mild reaction temperatures (40 °C) and short reaction times (~2 h), delivering excellent isolated yields (>75% macrocycles) and up to 30% of the 6-membered cyclophane, all under non-high-dilution concentrations (35-350 mM). Structural insights into APCs reveal variations in product distribution based on different endocyclic substituents, with steric properties of exocyclic substituents having minimal influence on the macrocyclization. Aryl-type endocyclic substituents predominantly yield 6-membered macrocycles, while polycyclic aromatic units such as fluorene and carbazole favor 4-membered species. Experimental and computational studies support a proposed mechanism of ring-walking catalyst-transfer that promotes the macrocycle formation. It has been found that the macrocyclization is driven by the formation of cyclic conformers during the oligomerization step favoring an intramolecular C–N bond formation that, depending on the cycle size, hinges on either pre-organization effect or kinetic increase of the reductive elimination step or a combination of the two. The CTM process exhibits a "living" behavior, facilitating sequential synthesis of other macrocycles by introducing relevant monomers, thus providing a practical synthetic platform for chemical libraries. Notably, CTM operates both under diluted and concentrated regimes, offering scalability potential, unlike typical macrocyclization reactions usually operating in the 0.1–1 mM range.

Published: May 2024

South African women own a modest share of businesses while being the majority of the population. Increasing the number of female entrepreneurs in South Africa is expected to reduce poverty and unemployment, empower women, ensure equity, and strengthen the economy. This article examined the development of women entrepreneurs in Cape Town through guided and funded business start-ups. Data were collected using a qualitative technique based on purposive sampling through semi-structured interviews with 17 participants. An interpretive paradigm and an explorative design were employed. The data was analysed using the ATLAS.ti software. According to the participants, many women-owned business start-ups are neither funded nor guided. The findings revealed that many women entrepreneurs do not support one another in business start-ups in Cape Town. Moreover, minimal effort is put into interventions by both government and the private sector to abate gender discrimination and eliminate the exclusion of women entrepreneurs. There are instances of gender bias that impede the development of women entrepreneurs. The findings confirm that the development of women entrepreneur-focused funding for start-ups has received scant attention in Cape Town. Many women entrepreneurs still do not receive developmental support. Among the proposed interventions to improve women entrepreneurship, start-up funding and guidance are platforms that encourage informal businesses to become formal and penetrate formal financial networks. This paper argues for lending models best suited for women entrepreneurs in South Africa.

This paper discusses the accessibility of people with reduced mobility (PMR) within public higher education institutions. Several researchers have approached this issue from different angles. They have identified several rights for PMRs, including the fundamental right to education, as recognized by the United Nations. Accessibility is defined as the ease of movement within the environment, achieved through the removal of architectural and technological barriers in public buildings. This study aims to show the impact of the architectural spatial configuration of the university on the social behavior of PMR accessing education. To achieve this goal and answer the research problem, a combination of two scientific research methods was used: a qualitative-quantitative method based on sociological surveys and observation, and a second method based on "spatial syntax," a morphological approach that reveals the close relationship between human beings and their built environment. The study was conducted at the Faculty of Architecture and Urbanism at Salah Boubnider University in Constantine. The study concludes that architectural design has a direct impact on the behavior of PMRs and their appropriation of space within the faculty. Designers need to consider measures and design techniques that facilitate access for this social category to higher education institutions in the development of architectural projects.

Published: May 2024

The concerns with the increasing rate of preventable accidents occurrences in Nigeria's manufacturing sector required a renewed focus on occupational safety and health (OSH). Specifically, despite the number of interventions and the amount of spending on interventions, the effects have remained minimal. Also, despite the efforts of researchers and their suggestions, little or no impact has been noticed as OSH continues to be inadequate. These problems call for a fresh approach and consultation with the individuals who will be utilising these solutions most directly (the workers) to address these issues at their core. This paper is part of a large mixed-method study designed to explore how to improve the efficacy of OSH in Nigeria. However, this present paper reports part of the initial phase as it examines the perception of blue-collar workers in the Nigerian industry to understand how well the existing measures have satisfied their safety needs from the standpoint of available human resource management practices (HRM practices). Hence, this work uses a cross-sectional research design to gather data from both registered and non-registered workplaces located in cities in three Nigerian states, totalling 633 required participants. A mix of simple random and convenience sampling techniques was applied to select the expected samples. SPSS software version 26 was used to analyse the 641 responses. The blue-collar workers constituted the unit of analysis for this phase. The findings indicated that there are diverse opinions among Nigerian manufacturing blue-collar workers regarding the accessibility and applicability of the HR practices under investigation. Based on the findings, recommendations for improving OSH practices in the manufacturing industry is suggested with the hope of maximising employee involvement in strengthening the efficacy of OSH interventions in Nigerian manufacturing workplaces.
Assesinng Sustainable Development Goal 11 in South African Context
Authors:   University of Johannesburg, South Africa, Vyas-Doorgapersad Shikha
Published: May 2024

South Africa underwent apartheid, a system of racial segregation, during which the country's governance agendas did not offer too much emphasis on environmental issues. The policies implemented during that time were lacking the environment-inclusiveness, and thus regrettably remained unsuccessful in promoting sustainable development. This article aims to review the current state of SDG 11, which focuses on sustainable cities and communities, in South African context. This research is a qualitative analysis of secondary data obtained through reviewing literature. The data was analyzed using conceptual analysis. The literature review shows that the democratic governance in a post-apartheid era implemented some policies that now regulate various aspects of SDG 11 in the country-specific context. Some of the significant ones are the Housing Act (No. 107 of 1997); Water Services Act (No. 108 of 1997); National Environmental Management: Waste Act (No. 59 of 2008); Municipal Systems Act (No. 32 of 2000); Breaking New Ground, 2004; and the National Housing Code, 2009. However, despite these legislative frameworks, there are challenges that still hamper the effective achievement of SDG 11. The findings therefore explore these challenges that include insufficient skills, inadequate funding, and inadequate training to develop technical competence, among others. The study provides recommendations for addressing these issues and improving the situation.

This paper examines the present 4IR’s predictive elements for sustaining organizational performance (OP) in the Nigerian banks. Therefore, in light of the existing 4IR, this article suggests strategies for improving and sustaining OP in the Nigerian banks. The report promoted a quantitative research method based on a survey study design. The findings indicated that, within the Nigerian banks in the 4IR, employees' polychronicity (EP), Leadership 4.0 (L4.0), and perceived organizational support (POS) significantly and jointly predicted the sustainability of OP. Thus, it is recommended that human resource professionals, organizational managers, and the Nigerian banking industry promote strategies for enhancing and maintaining organizational performance. These strategies include encouraging employees to adopt a polychronic mindset, increasing Leadership 4.0, and offering regular organizational support. Thus, this paper has recognized organizational support, Leadership 4.0, and employees’ polychronicity as significant influencers in predicting factors in sustaining organizational performance in the Nigerian banking business during the Fourth Industrial Revolution.

The Zimbabwean government has instigated various policies and strategies as part of e-government initiatives to provide members of the public with convenient access to health information and services. Efforts have been made to embrace ICTs in Zimbabwe’s public health sector. The performance of health institutions in Zimbabwe however continues to deteriorate at a time when the use of ICTs in health is gaining momentum in Africa. This paper therefore seeks to assess the implementation of the E-health strategy revealing the current state of e-health or digital technology systems in Zimbabwe’s public hospitals. The study adopted an exploratory research design. Participants in this study were selected using purposive sampling. Data were gathered through participant observations, in-depth interviews and documentary research. The study established that even though e-health is an indispensable tool in improving quality, timely and cost effective health care, its implementation in Zimbabwe has not been easy and it is still in its infancy stages. The study concluded that e-health is a reliable tool for promoting successful and effective public health service provision in Zimbabwe. The study therefore reflects and proposes elements necessary for the successful implementation of e-health in Zimbabwe’s public health sector.

Introduction: The presence of critical patients being treated in intensive care can hurt on the physical and psychological condition of their families, including lack of attention to personal hygiene, insomnia, decreased appetite, anxiety, depression and post-traumatic syndrome disorder (PTSD). This negative impact can be minimized through the role of nurses by meeting the family's needs while the patient is being treated in the intensive care room. Objective: This research aims to determine the description of meeting the needs of families of critical patients by nurses in the ICU at Ario Wirawan Lung Hospital, Salatiga. Method: The design of this research is descriptive with a survey approach using a questionnaire developed from the Critical Care Family Needs Inventory (CCFNI). The sampling technique used was total sampling with a total of 30 nurses as respondents. The data analysis used is univariate and bivariate. Results: Research shows that the majority of respondents, 60% or 18 nurses, have a good role. On average, the categories for fulfilling the needs of the patient's family carried out by nurses were the same, namely the good and bad categories for 15 respondents or 50%. Bivariate analysis results p value = 0.000 (< 0.05). Conclusion: There is a relationship between the role of nurses and meeting the needs of the families of patients treated in the ICU.

Published: May 2024

Objective: To explore the therapeutic effect of myofascial therapy on cervical spine diseases. Methods: A total of 60 patients diagnosed and treated for early-stage cervical spondylosis at Beijing Language and Culture University Hospital from January 2021 to June 2022 were selected. Using the random number table method, patients were divided into a control group (30 cases) and a myofascial therapy group (30 cases). The improvement of symptoms such as pain level, cervical spine function, and quality of life of both groups before and after treatment was evaluated. Results: Compared with the pre-treatment phase, the myofascial therapy group showed a statistically significant reduction in the VAS score and NDI score after treatment (P < 0.05). Additionally, the CSQ of patients in the myofascial therapy group significantly improved after treatment, with the CSQ-8 score showing a significant increase (P < 0.05). Conclusion: Myofascial therapy proves effective in alleviating various uncomfortable symptoms occurring in the early stages of cervical spondylosis. It significantly reduces soreness and pain in cervical spine-related muscles and plays a crucial role in improving the physiological curvature of the cervical spine. This therapy deserves promotion and widespread application in the treatment of cervical spondylosis.

A Study on the Relationship of the Melodies of “Jinjak 3”, “Daeyeop”, and “Mandaeyeop”
Authors:   National Gugak Center, Kang Hyejin
Published: May 2024

The pieces of daeyeop, considered as the original form of the classical vocal genre
gagok, are very important sources that show the process through which Mandaeyeop
in Geumhapjabo (the scores of plucked zither geomungo) was derived from “Jinjak”
compiled in Daeakhubo (the scores of court music). This study aims to reveal the
relationship of the melodies of Jinjak 3, Daeyeop, and Mandaeyeop, distinguishing
daeyeop's melodic phrases and analyzing their melody structures. It focuses on four
daeyeop pieces for analysis--Pyeongjodaeyeop from Siyonghyangakbo (lit. the
Joseon-style scores used at the time), Daeyeop, Pyeongjodaeyeop aka Naksujo, and
Daeyeop Kim Jong-son from Hyeongeumdongmunyugi (a collection of records and
scores related to geomungo).
The melody analysis in this study was conducted by distinguishing the structural notes
from the melodic notes in the melody for each phrase and extracting the skeletal melody
of the phrase unit connecting structural notes. As a result of extracting and comparing
the skeletal melodies of Jinjak 3 and Mandaeyeop, it was found that the skeletal
melodies of the second half of daeyeop and buyeop of Jinjak 3 were similar to chapters
3 to 5 of Mandaeyeop. As a result of classifying the phrases of the four daeyeop pieces
and extracting and analyzing the skeletal melody for each phrase, the melodies of the
four daeyeop pieces shows differences for each piece.
Chapters 1 and 2 of the daeyeop pieces were not directly influenced by the melody
of Jinjak 3, but similar skeletal melodies are used among the daeyeop pieces. Chapter
2 of the daeyeop pieces generally uses a changed one from the melody of Chapter 1,
but the melodies of Chapters 1 and 2 of the daeyeop pieces in Hyeongeumdongmunyugi
appear more similar than those in Pyeongjodaeyeop. The melodies of the daeyeop
pieces show the greatest difference in chapter 3. In other words, while Chapter 3 of Pyeongjodaeyeop uses a melody similar to Jinjak 3, Chapter 3 of the three daeyeop
pieces in Hyeongeumdongmunyugi uses similar melody to Chapter 5 of the same piece.
The melody of Chapter 4 of the daeyeop pieces in Hyeongeumdongmunyugi uses higher
notes than that of Chapter 4 of Pyeongjodaeyeop and has a complex form, so it is
clearly distinguished from the melody of Chapter 5. In addition, the form of daeyeop
pieces in Hyeongeumdongmunyugi continues to that of Mandaeyeop in Geumhapjabo.
Therefore, it can be said that daeyeop pieces show a transitional period in which the
form of Jinjak 3 was changed into that of Mandaeyeop.
This study reveals that Pyeongjodaeyeop, which has a melody similar to that of
Jinjak 3, was transformed into the daeyeop pieces of Hyeongeumdongmunyugi, which
have a melody and form distinct from Jinjak 3, and then was established as
Mandaeyeop in Geumhapjabo. In addition, it confirms that the daeyeop pieces in

Ülkelerin kalkınma sürecindeki vazgeçilmez faktörlerden birisi olan üretimin kesintisiz bir şekilde sürebilmesi için uygun maliyetli, sürekli, güvenli ve temiz enerjiye ulaşabilmeleri büyük önem arz etmektedir. Ülkeler bir yandan büyümeye devam ederken, diğer yandan 2030 için belirlenen 2° ve 2050 yılına kadar karbon nötr hedeflerini göz önüne almak durumundadır. Bu amaç doğrultusunda çeşitli sektörel inovasyonların kullanılması gerekmektedir. Bu derlemede, küresel enerji tüketimi ve karbon salınımının başlıca sorumlularından olan sanayi sektöründeki güncel enerji verimliliği çalışmalarıyla ilgili yerli ve yabancı kaynaklar taranarak, ulaşılan olası çözüm önerileri başlıklar altında aktarılmıştır. Araştırmalar sonucunda, atık ısı geri kazanım sistemi ile ısıtma veriminin %32,32 artarak tüketilen elektrik enerjisinin yaklaşık %30’nun geri kazanılabildiği hesaplanmıştır. Kojenerasyon sistemlerinin var olan yapıya entegresi ile gaz türbinlerinin elektrik dönüşüm verimliliğinin %30-40 seviyelerinden %80-90‘lara çıktığı görülmüştür. Yapılan denetimlerde yatırımın kendini 1,5–3 yıl gibi bir sürede amorti ettiği tespit edilmiştir. Karbon nötr hedefi doğrultusunda geliştirilen bir diğer yöntem olan karbon yakalama teknolojisi üzerine yapılan çalışmalarda, demirçelik gibi karbon yoğun sektörlerde yöntemin CO_2 salınımını %65’e varan oranlarda düşüreceği hesaplanmaktadır. Çalışmanın devamında, Türkiye’nin enerji görünümü, yürürlükte olan verimlilik politikaları ile güncel sanayi istatistikleri derlenerek, endüstrideki enerji verimliliğini artırmaya yönelik çalışmalar yürütecek akademi ve özel sektör çalışanlarına katkıda bulunulması amaçlanmıştır. Sanayi sektörünün önemli bir tüketim kalemini oluşturduğu Türkiye’de, bu alanındaki en kapsamlı yasal düzenleme 2007 yılında yayınlanan 5627 sayılı Enerji Verimliliği Kanunu ve güncel versiyonu 2018’de paylaşılan ISO 50001 Enerji Yönetimi Sistemi Standardı’dır. Firmalara yapacakları temiz üretim teknolojileri uygulamalarının maliyetlerini yükseltmeyeceği gibi, aksine ekonomik açıdan da geri dönüşü kısa yatırımlar olduğunun aktarılması sanayi genelinde farkındalığı artıracaktır. Türkiye’deki sanayi sektörünün enerji tasarruf potansiyelinin en az %20 olduğu ve bunun yaklaşık %50'sinin küçük yatırım miktarları ile iki yıldan az sürede kendini amorti ederek gerçekleşebileceği tespit edilmiştir. Yenilenebilir Enerji Genel Müdürlüğü’nün çalışmalarına göre, sanayi sektöründe atılacak doğru adımlar ile Türkiye’nin toplam birincil enerji talebinin %15 düşürülebileceği hesaplanmıştır.
Technological substitution: The key control modes
Authors: Sukharev Oleg S.
Published: May 2024

One of the primary goals of public administration in Russia is ensuring technological sovereignty which is hard to attain without proper planning and coherent technology modernization policy in different fields of economic activity. However, administration tools should allow for the current stage of technological development. The article aims to identify control modes of technology modernization considering the principles of substitution and addition. The foundation of research resides in technological change theory. The research methods applied are taxonomic and structural analysis, statistical generalization. Empirical evidence for 2004–2021 was retrieved from the Russian Federal State Statistics Service (Rosstat). This methodological approach has allowed establishing the key control modes and types of technology modernization – substitution and addition – according to investment in high or low technology, and formulating their central principles. The study also discusses the variants of state policy aiming to extend the country’s technological sovereignty based on the current mode of technological modernization. It is shown that the pseudo effect of technological dualism discovered in the Russian economy suggests utilising special tools designed to optimize the economic structure for boosting investment in new technologies.

PT Jasa Marga merupakan perusahaan besar di Indonesia yang berperan dalam pengembangan dan pengoperasian jalan tol yang dikenal sebagai salah satu perusahaan blue chip dengan saham LQ45. Namun, harga sahamnya memiliki volatilitas tinggi atau naik dan turun dengan cepat sehingga nilainya selalu berubah-ubah. Oleh karena itu, diperlukan adanya peramalan guna memprediksi harga saham PT Jasa Marga di masa yang akan datang guna mengetahui pergerakan harga sahamnya. Metode Autoregressive Integrated Moving Average (ARIMA) merupakan salah satu metode yang dapat meramalkan data dengan volatilitas tinggi, namun memiliki kekurangan pada residual yang mengandung heteroskedastisitas. Sehingga, dilakukan penambahan model Generalized Autoregressive Conditional Heteroskedasticity (GARCH) guna mengatasi masalah heteroskedastisitas yang awalnya, ditimbulkan model ARIMA sehingga dapat meramalkan data dengan volatilitas tinggi secara lebih optimal. Oleh karena itu, penelitian ini menerapkan metode ARIMA-GARCH guna menemukan model terbaik untuk meramalkan indeks harga saham harian PT Jasa Marga. Data yang digunakan berasal dari indeks penutupan harga saham harian PT Jasa Marga (Persero) periode Januari 2015 hingga Mei 2023. Pengukuran ketepatan peramalan menggunakan Mean Absolute Percentage Error (MAPE). Hasil peramalan menunjukkan model terbaik menggunakan ARIMA (2,1,1) - GARCH (1,3) dengan nilai MAPE sebesar 6,825728% yang mengindikasikan hasil peramalan sangat baik karena nilai MAPE < 10%.

Una aproximación cuantitativa a la producción de artículos de investigación en literatura en el campo académico chileno actual
Authors: Rosas Lira Marcela
Published: May 2024

Este artículo se propone describir, desde la mirada funcional propia del concepto de campo de Pierre Bourdieu, la situación actual del campo académico literario chileno desde una dimensión cuantitativa. Para este fin, se analiza la producción de artículos de investigación en literatura en revistas académicas nacionales durante el periodo 2010-2019, con el objetivo de ampliar la posibilidad de descripción del campo y sus dinámicas. A diferencia de otras líneas referidas, esta aproximación al campo académico integra nuevos agentes e interacciones, con énfasis en la intersección problemática entre los ámbitos literarios, académicos y científicos en torno a la producción de artículos de investigación en literatura.
Pérdida de aspiración profesional y demérito en la autoimagen desde la disponibilidad léxica comparada, pre y postpandemia, en estudiantes de nivel secundaria
Authors: Reyes Valdés Dalia , Reyes Valdés José , Segura Abril Lourdes
Published: May 2024

Se analizan dos corpus de disponibilidad léxica obtenidos de sendas muestras conformadas, cada una, con 180 estudiantes mexicanos de nivel secundaria, con recogidas en 2019 y 2022, respectivamente. El objetivo fue explorar la variabilidad numérica y semántica en la adquisición de vocabulario en adolescentes durante el periodo de pandemia COVID19 y su trascendencia en el comportamiento prospectivo de empleabilidad y autopercepción. Se fundamenta el estudio desde la propuesta conceptual de disponibilidad léxica ofrecida por Reyes y Flores (2018), en tanto que el fundamento psicológico para la interpretación de la variabilidad en la disponibilidad se basó en parámetros que emergen de los postulados básicos de la teoría de los marcos relacionales (Barnes-Holmes et al., 2005). La metodología partió de la recogida de datos, utilizando el test estandarizado para calcular el índice de disponibilidad léxica (López, 2004) organizado en cuatro centros de interés: profesiones, empleos potenciales, pasatiempos y autopercepción. En la primera fase, el análisis estadístico de los resultados se realizó con software libre R con IDE RStudio, con un enfoque cuantitativo comparativo. Las categorías de análisis para la segunda fase fueron: cambios de posición, aparición/pérdida de vocablos, fuerza ilocutiva/enunciativa de adjetivos y autoeficacia en términos analíticos de oposición, conducta arbitraria, influencia social y auto discriminación. Se localizaron resultados en tres grandes ámbitos: mínima adquisición de vocablos frecuentes, desplazamiento de preferencias aparentemente mediadas por la pandemia y pérdida aspiracional de profesiones. En la muestra postpandemia permeó una gran cantidad de “palabras de resistencia” y, en el caso de las mujeres, se halló emergente incidencia en el demérito de la autoimagen.
¡La pucha que vale la pena! De eufemismo a marcador de modalidad
Authors: Kornfeld Laura Malena
Published: May 2024

Este trabajo se propone sistematizar los usos y valores gramaticales de pucha (y una serie de variantes) en distintos países hispanoamericanos y analizar, en particular, su uso como marcador de modalidad en pucha que. En primer lugar, aportamos datos dialectológicos contrastivos y en algunos casos diacrónicos. De este modo, ubicamos la distribución de las dos acepciones de la interjección ¡pucha!, la de ‘contrariedad’ (más extendida en América hispana) y la de ‘admiración’ (registrada en toda América del Sur hispana y Honduras), así como de las variantes que introducen una proposición completa y que funcionan como marcadores de modalidad: pucha que (presente en el Cono Sur, Perú y, en menor medida, Colombia) y pucha si (restringido al Río de la Plata). En segundo lugar, analizamos las propiedades gramaticales de pucha que para concluir que introduce desde el punto de vista proposicional una cuantificación en un evento que se da por cierto y se afirma rotundamente, pero que además funciona pragmáticamente como un marcador de la modalidad exclamativa, igual que los pronombres exclamativos cuán, cuánto y cuánto/a/s. Las repercusiones epistémicas de pucha que son exactamente las mismas que se dan con los pronombres exclamativos, con quienes pucha que comparte (casi) todas sus propiedades gramaticales, semánticas y pragmáticas.
El matadero, una novela prospectivamente histórica muy original
Authors: Molina Hebe Beatriz
Published: May 2024

Echeverría es el poeta más importante de la generación argentina de 1837, no obstante, se lo recuerda más por El matadero, texto narrativo que denuncia la barbarie del gobierno de Juan Manuel de Rosas y que es publicado póstumamente. Desde la perspectiva de la poética histórica, analizamos la modalidad genérica de El matadero, a fin de apreciar tanto la originalidad que busca el autor como los contratiempos que padece no solo por su marcada preferencia por la poesía, sino también por la inadecuación de las formas tradicionales al contenido subjetivo que lo convoca. Pretendemos demostrar que el modelo de su proyecto escritural es la novela prospectivamente histórica, al que Echeverría ajusta creando un efecto sublime, similar al de la poesía: un golpe de comprensión y emoción para conmover al lector, mediante la escena final de vejación y muerte de un joven unitario. No obstante, el resultado textual parece no satisfacer al escritor y tal vez por ello queda inédito y escondido.
