The impact of foreign direct investment on green innovation efficiency: Evidence from Chinese provinces
Authors: Zhong Shen , Zhou Zhicheng , Jing Hongjun
Published: February 2024

Improving green innovation efficiency (GIE) is the key to achieve high-quality economic development in China, and the introduction of foreign direct investment (FDI) has become an important path choice to promote the GIE. Based on the data of 30 provinces in China, this paper explores the linear and nonlinear effects of FDI on GIE from both quantity and quality perspectives, and further analyzes the mediating role of environmental regulation level. The results show that: (1) From 2011 to 2020, the GIE of all provinces in China generally shows an upward trend. (2) The quantity and quality of FDI have a significant positive impact on the improvement of GIE in China’s provinces, and this impact has regional heterogeneity. (3) The quantity and quality of FDI can promote the improvement of GIE in China through the level of environmental regulation (ER). (4) With the level of knowledge accumulation and GIE as the threshold variables, the quantity and quality of FDI have a single threshold effect on the GIE of China’s provinces. The conclusions of this study provide some policy implications for local governments to make full use of FDI to perform green innovation activities.
‘Multiple belongings’ in Zoë Wicomb’s ‘My Name Is HannaH’ (2005)
Authors: Fossati Marta
Published: February 2024

This article examines the short story/essay ‘My Name is HannaH’ (2005) by South African-born writer Zoë Wicomb, focusing on its generic hybridity, its translocal quality and its deeply intertextual structure. Retracing the life and works of the South African poet Arthur Nortje through the artifice of fiction, Wicomb exposes the discursive and relational nature of space and identity. By analysing the story’s extremely heterogeneous intertexts and its playful generic inbetweenness, I seek to show how Wicomb refuses any form of categorization or fixed notion, exposing, rather, the seams and fissures of the textuality of reality. Ultimately, I argue that the thematic and formal features of the selected narrative can foreground the relationship between world literature and the short story as a liminal, cosmopolitan and mutable genre, particularly appropriate for the representation of the interconnectedness of our society.
Short story writing and garden making: Topia and heterotopia in Jhumpa Lahiri’s ‘Unaccustomed Earth’ (Unaccustomed Earth)
Authors: Tollance Pascale
Published: February 2024

‘Unaccustomed Earth’ presents us with an instance of dis-location that is not just connected with geographical displacement but with a melancholy that runs deep in Lahiri’s fiction. Somewhat unexpectedly, dis-location also works as a force that challenges fixity and inertia and becomes part and parcel of a process of mourning. This article proposes to approach Lahiri’s story through the notion of heterotopia, which Foucault defines as a paradoxical place, a place which is real, unlike utopia, yet ‘outside all places’. In the opening story of the collection, it is a garden created from scratch by a child and his grandfather which offers a beautiful example of how place itself may be displaced and efface itself behind place-making. Lahiri’s story challenges the too obvious association of the garden with rootedness and disturbs the binary opposition between place and placelessness: as it is, the garden that is being shaped means something different and works differently for everyone, opening a space not just for expectations but for the indeterminate and the unexpected. Just like the small patch of earth it contains, the limited space of the short story turns out to encompass far more than what appeared at first. Firmly inscribed in a part of the world that can be placed on a map, Lahiri’s story also detaches itself from that particular location as its metafictional and intertextual dimensions assert themselves with greater clarity.
Molde para la elaboración de mangos decorados de cazos de sigillata hispánica procedente del alfar romano de La Cereceda (Arenzana de Arriba, La Rioja)
Authors: Sáenz Preciado Jesús Carlos , Sáenz Preciado María Pilar , Antoñanzas Subero María Asunción
Published: February 2024

En este artículo damos a conocer un molde para la elaboración de mangos decorados de cazos de sigillata (forma Hisp. 81). El molde apareció en el alfar romano de La Cereceda (Arenzana de Arriba, La Rioja) ubicado en el Complejo Alfarero de Tritium Magallum en el valle del río Najerilla-Yalde, que es el principal centro alfarero de Hispania. El estudio de este alfar, en el que venimos trabajando en los últimos años, está permitiendo conocer un taller alfarero cuya producción decorativa es excepcional dentro de las producciones que englobamos en la sigillata hispánica. Consideramos que este alfar está estrechamente vinculado con la legio VII gemina felix, una de cuyas unidades estuvo ubicada en Tritium. Del mismo modo, planteamos una posible vinculación de este alfar con la dinastía Flavia, desarrollando una decoración de tipo propagandístico. El molde estudiado, así como otros para fabricar cuencos Hisp.37, se recuperó durante un seguimiento arqueológico de la concentración parcelaria realizada en la zona dirigido por la empresa de arqueología Labrys. En este artículo efectuamos un estudio sobre este cazo, su funcionalidad y una serie de reflexiones sobre esta forma. Se trata del segundo molde conocido de este tipo, el único completo que ha aparecido hasta el momento, con una decoración única para la que no hemos encontrado paralelos, estando vinculada con la divinidad de Victoria y los cultos solares. Fechamos el molde, y por lo tanto los cazos elaborados a partir de él, en época de Domiciano, coincidiendo con el momento de esplendor del alfar y del proceso de reestructuración de la industria alfarera tritiense.

Published: February 2024

En este trabajo presentamos los mármoles y otros materiales pétreos de prestigio de época romana hallados en la llamada Casa de la Cañada Honda de Itálica (Santiponce, Sevilla) –concretamente en la ampliación adrianea de la ciudad, la conocida como Nova Vrbs–, tanto los encontrados en las últimas campañas de excavación iniciadas en el año 2017 y llevadas a cabo por el equipo liderado por Rafael Hidalgo Prieto, de la Universidad Pablo de Olavide de Sevilla (UPO), como los que se conservan in situ en la domus, en los umbrales de las estancias y en los suelos documentados. El estudio e identificación macroscópica de los materiales, con el análisis cuantitativo de los tipos de marmora, se complementa con un estudio en profundidad de algunas piezas singulares: piezas con notae lapicidinarum, placas de revestimientos en opus sectile parietales y de pavimentos, suelos con incrustaciones marmóreas reutilizadas, pistillum y mortero. Además, se ha realizado un estudio del empleo de los materiales pétreos en los distintos espacios de la vivienda. Los resultados evidencian la presencia de rocas ornamentales de procedencia local, así como de materiales lapídeos de la Lusitania, junto con una serie importante de marmora de las principales canteras del imperio romano, aunque corresponden a momentos de la Antigüedad Tardía, de acopio de materiales lapídeos reutilizados de estructuras de fechas anteriores. La mayor parte de estas rocas ornamentales debe proceder de un imponente espacio público, situado en las cercanías de la casa, el santuario de culto imperial, de grandes dimensiones, el Traianeum de Itálica, un complejo arquitectónico conformado por un gran templo y un altar, dentro de una plaza rodeada por un pórtico cerrado y hekatostylon, en el que se emplearon para su decoración una gran diversidad de tipos de marmora.
Az északi számi lelkész, Anders Porsanger jelentése Sajnovics Jánosról és a magyar helyesírásról
Authors: Kelemen Ivett
Published: February 2024

In 1770, in Copenhagen, János Sajnovics (and Maximilian Hell) on his way home from an astronomical expedition proposed the development of the North Saami spelling according to the Hungarian model. The idea aroused such enthusiasm among the Danish-Norwegian senior supporters (cf. Otto Thott, then president of the Danish Scientific Society) that Sajnovics’ proposal was put into practice: The first 42 sheets of the Lexicon Lapponicum Bipartitum dictionary by Norwegian linguistics professor Knud Leem, which presumably had already been in print, were transcribed in Hungarian spelling. For this work, he also had a North Saami native speaker assistant, Anders Porsanger. After the joint work, Porsanger sent a 7-page report to the Mission College in Copenhagen on 7 July 1770 commenting on the work with Sajnovics. In this article, I will present the letter's contents, emphasizing the information about Sajnovics, their relationship, their joint work, and Porsanger's opinion on Hungarian orthography.
A számi viselet szerepe a kortárs vizuális kommunikációban
Authors: Tamás Ildikó
Published: February 2024

The author in her article analyses the complicated relations of ethnicity and art on the example of the Sámi ethnical symbols. She presents in what context of historical events and ideological trends the idea of panSamiism has evolved, in what way the issue of the Sámi nation emerged in political and cultural scenes and what central symbols were used by Sámi artists to ensure the success of the new identity discourse. Sámi people living in four states have nowadays a strong sense of belonging. The public appearance of Sámi politicians, public figures, artists is always marked with some Sámi costume or other symbols that visually represent Sámi identity. These visual symbols express Sámi unity, rejection of ‘western’ ideologies and their community and solidarity with other indigenous peoples of the world. Sámi symbols that had been formerly stigmatized in Scandinavia received new meanings and became accepted by the second half of the 20th century, and finally, their popularity exceeds the borders of Sámi communities.
VIABILITY OF LACTIC ACID BACTERIA (

L. acidophilus) IN PROBIOTIC READY TO DRINK JUICES
Authors: Concepcion Remilyn , Barcelon Eufemio , Braga Jason , Mojica Analyn
Published: February 2024

Probiotics are consumed in dairy based goods, however, given the rise in various diet types, non-dairy alternatives, such as inoculating fruit juices with probiotics were studied for substitute.

Lactobacillus acidophilus is a probiotic strain exerting a number of human health benefits. Therefore, the objective of this study was to determine the viability of

Lactobacillus acidophilus in different non-dairy substrate to produce a Probiotic Ready to drink (RTD) juice blend made of malunggay, pineapple and mango over 24 hours of fermentation and 21 days of refrigerated storage. The secondary objective was to determine the sensory parameters using 9-point Hedonic scale and physicochemical properties of probiotic RTD Juice Blend in terms of pH, TSS and total acidity. All of the probiotic RTD Juice Blend samples achieved a mean viable count of at least 10

6 CFU/mL during 24 hours of fermentation and 21 days of refrigerated storage. According to the sensory evaluation, which evaluated samples according to color, aroma, taste and overall acceptability, probiotic RTD juice blend with malunggay-pineapple-mango blend proved to have the highest score for all characteristics with pH of 4.62, TSS of 13.47

OBx and total acidity of 0.47%. The pH and TSS decreases with time while acidity increases. This condition is good for the production of microbes because low pH can decrease the microbes’ production rate. This environment may enable LAB to successfully pass the pH of the stomach and bind in the gut of the host which is needed for successful colonization and propagation for expression of its health-promoting effects. Therefore, this study indicated a potential for probiotic fruit juices as a valid alternative to dairy based probiotic products.

Efeitos do empoderamento psicológico no comprometimento organizacional, ambiguidade de papéis e desempenho gerencial em ambiente de baixa participação orçamentária
Authors: Friedrich Marcos Paulo , Zonatto Vinicius Costa Da Silva , Lavarda Carlos Eduardo Facin , Lunardi Micheli Aparecida
Published: February 2024

Objetivo: Analisar os efeitos do empoderamento psicológico no comprometimento organizacional, ambiguidade de papéis e desempenho gerencial em ambiente de baixa participação orçamentária.
Método: Pesquisa descritiva, desenvolvida por meio de levantamento, com aplicação de questionário e análise quantitativa dos dados (path analysis), foi realizada com amostra não aleatória e compreendeu 183 gerentes de nível médio, que atuam com atribuições como gerente geral e gerente administrativo em uma instituição financeira estatal da região sul do Brasil.
Resultados: Os resultados revelaram uma influência positiva do empoderamento psicológico no comprometimento organizacional e no desempenho gerencial, no entanto, uma influência negativa é percebida entre o empoderamento e a ambiguidade de papéis. Os achados também revelam que o comprometimento organizacional possui relação positiva com o desempenho gerencial. As evidências encontradas permitem concluir que em contextos específicos de ambiente de baixa participação orçamentária, o empoderamento psicológico pode ampliar o desempenho gerencial, por meio do aumento do comprometimento organizacional e da redução da ambiguidade de papéis. Verificou-se que quanto maior o comprometimento organizacional, maiores são os efeitos do empoderamento psicológico sobre o desempenho gerencial.
Contribuição: O ambiente de baixa participação orçamentária é caracterizado como um contexto em que gestores de nível médio não possuem autoridade para a definição de objetivos e metas, bem como no processo de elaboração do orçamento. Neste contexto, esse estudo contribui para o entendimento dos efeitos psicológicos e comportamentais no desempenho gerencial em ambientes de baixa participação orçamentária, indicando aos gestores de nível superior das entidades estatais os efeitos comportamentais percebidos por gerentes de nível médio, em decorrência da configuração orçamentária adotada.
Las prácticas integrales como camino a la utopía
Authors: Zavaro Pérez Carlos Alberto
Published: February 2024

Las prácticas integrales suponen un camino a transitar por parte de la academia en el intento por trascender el paradigma de las funciones escindidas y de la extensión transferencista como práctica acrítica de vinculación con la comunidad. El artículo analiza algunos de los descriptores que caracterizan el formato de las prácticas integrales entendiéndolas como una forma de integrar funciones, saberes, disciplinas en un espacio de aprendizaje situado que privilegia el territorio y el contacto con la comunidad desde una perspectiva dialógica, multiactoral, interdisciplinaria e intersectorial donde es posible construir sentido colectivamente. De esta manera, se proponen y describen algunos dispositivos que permiten objetivar este tipo de experiencias. Se sostiene que un formato de esta naturaleza contribuye no solo a la formación de futuros profesionales comprometidos con la comunidad, sino también a la posibilidad de transformación de las universidades en la sociedad en que se inserta.
A vueltas con la «muerte de dios» en Nietzsche. La «muerte de dios» como categoría transversal de la filosofía vitalista nietzscheana
Authors: Casadesús Ricard
Published: February 2024

Podríamos calificar a Nietzsche de un profeta heroico e innovador, que hace un oráculo de la decadencia, denunciando el triunfo de lo suprasensible, de lo ideal, la imposición de otro mundo como la historia de un error, de una ilusión, fuente común de todas las ficciones, prejuicios y dogmatismos de la tradición cultural occidental. Sin embargo, el pensamiento que Nietzsche expresa con la muerte de dios, y que conlleva el fin del cristianismo y de la metafísica, tiene un origen metafísico y un origen genuinamente cristiano.
Aproximación a una derivación política de la ontología de Martin Heidegger
Authors: Ordóñez-García José
Published: February 2024

El presente trabajo trata de componer una ontología política, teórica y práctica, que puede considerarse como una aportación al desarrollo de lo que se viene conociendo, desde hace algún tiempo, como «izquierda heideggeriana» y que no ha expuesto de forma clara ni sus fundamentos ni su viabilidad. Así pues, este intento por establecer dichos fundamentos toma como punto de partida algunos de los existenciarios, que pueden dan lugar a esa deriva política, cuya particularidad es su distanciamiento de toda ideología al uso, por cuanto su horizonte «ontológico» es lo político en tanto que posibilidad de la política, es decir, la correlación pre-ontológica entre el «ser-con» (mit-sein), que es la posibilidad de apertura a la vida en común, y el régimen — si es que ello es posible— que pudiera establecerse a raíz de ello.
Heidegger y los nombres del origen
Authors: Martínez Matías Paloma
Published: February 2024

Este trabajo investiga el sentido que la cuestión del origen adquiere en el pensamiento de Martin Heidegger, cuestión íntimamente entrelazada con su interrogación por el ser y cuya comprensión exige atender a las variaciones que ésta experimenta en su trayectoria filosófica. Partiendo de esta premisa, se indaga en un primer momento sobre el papel que el concepto de lo originario juega en Ser y tiempo, tanto en la determinación ontológica del Dasein como en la dilucidación del sentido de su ser, identificado con la temporalidad originaria. En un segundo paso, las conclusiones obtenidas conducen a examinar la tematización del problema del origen en la obra heideggeriana posterior. Si ésta se caracteriza por la reflexión sobre la metafísica como acontecimiento clave de la historia occidental, en ella Grecia aparece como un origen ya definitivamente perdido e irrecuperable en su pérdida, pero cuya ausencia no sólo configura la emergencia de la modernidad, sino también nuestra actualidad histórica como última etapa de la misma.
De la problemática del sujeto al yo del deseo. De Girard a Oughourlian y Morin
Authors: Moreno Fernández Agustín
Published: February 2024

El presente trabajo desarrolla dos grandes objetivos. Por un lado, expone sintéticamente parte de la problemática filosófica y epistemológica del sujeto y del yo, mostrando la diversidad de conceptos y de genealogías históricas, así como parte de las controversias contemporáneas, elucidando preguntas y respuestas y apostando por vías no reduccionistas o simplificadoras. Por otro lado, se pretende solventar la paradoja de René Girard entre deconstrucción y reivindicación del sujeto, a través del yo del deseo de Jean-Michel Oughourlian y del paradigma de la complejidad de Edgar Morin.
El «oikos» como referente simbólico en condiciones de adversidad
Authors: García-Marín Eulalia
Published: February 2024

El texto plantea la importancia del oikos griego en tanto referente simbólico que puede permitir, en condiciones de adversidad, la construcción de una estética de la existencia que se constituya en una opción para seguir viviendo cuando las condiciones son desfavorables para la existencia de la vida y para la vivencia del hogar, es decir, en escenarios de conflicto como los que actualmente viven muchas personas en condición de refugiados, de inmigrantes, de asilados; así también quienes están secuestrados y aquellos que viven el desplazamiento forzado y ambiental. Tomaremos como referente de la adversidad lo sucedido en el campo de concentración de Auschwitz para relacionar aquellos hechos de crueldad con muchas de las situaciones que acontecen hoy en el panorama global. Todo esto con la idea de proponer la vivencia del oikos como una construcción íntima que manifiesta la vida y que puede convertirse en un refugio en circunstancias difíciles.

Este texto se centra en la génesis de las ciencias sociales a través de una reflexión analítico- descriptiva sobre la sistematización de la ciencia. La ciencia es una creación del ser humano y constituye la mejor herramienta para adquirir conocimientos acerca de su entorno, de sí mismo, del universo... Debe ser interdisciplinaria y para dar soporte a este empeño, hemos tenido que elegir, y hemos optado por comparar la sociología con la filosofía buscando aportaciones (implícitas o explícitas) de prestigiosos pensadores.

Seventy Years of Marriage and Family Law in China: Achievements, Challenges and Prospects
Authors: Guo Qingmin
Published: February 2024

This article examines marriage and family law in China from a diachronic perspective. It discusses three issues – the principal achievements over the last 70 years; the existing challenges since the 21st century; and its prospects for the future. The Marriage Law of the People’s Republic of China passed in 1950 was the first basic law after the founding of the People’s Republic of China and opened a new chapter in the development of Chinese marriage and family law. Significant development has been achieved both in systematic structure and institutional contents after undergoing three major revisions in 1980, 2001 and 2020. Despite the achievements made, great challenges remain since the 21st century, especially the difficulties in family formation and maintenance; population aging with fewer children; application of assisted reproductive technology; and prevalence of divorce, remarriage, and cohabitation. The future improvement of marriage and family law may focus more on maintaining family stability and building family civilization.
Reductive behavior of nickel and iron metallization in magnesian siliceous nickel laterite ores under the action of sulfur-bearing natural gas
Authors: He Zhien , Li Bo , Wei Yonggang
Published: February 2024

This study is a process for the preparation of advanced nickel–iron alloys by selective reduction of nickel-poor laterite ores using a variety of reducing agents. The first part of the experiment was the reduction of nickel laterite ore using natural gas; the reduction yielded mostly nickel metal and a small amount of iron forming fine nickel–iron particles. Fine nickel–iron particles are formed through the reduction of nickel and a small amount of iron oxides. These particles are dispersed and embedded within silicates. Additionally, H2S present in natural gas reacts with iron oxide, resulting in the formation of FeS. This, in turn, forms a low melting point eutectic with Fe, which reduces surface tension and promotes the growth and aggregation of nickel–iron particles. This study aimed to investigate the effects of various parameters such as roasting temperature, roasting time, natural gas concentration, and nickel laterite pellet on the formation and aggregation of ferronickel particles in low-grade nickel laterite ores. The results showed that the optimum reduction parameters were achieved at 900°C, 120 min, 40% natural gas concentration, and 40–60 mesh nickel laterite size, with roasting temperature being the most important factor followed by natural gas concentration, roasting time, and nickel laterite pellet. Using these parameters, the metallization rates of Ni and Fe were found to be as high as 95.3 and 8.5%, respectively.
Perceptions of nursing staff and students regarding attrition: a qualitative study
Authors: Mazzotta Rocco , Durante Angela , Bressan Valentina , Cuoco Angela , Vellone Ercole , Alvaro Rosaria , Bulfone Giampiera
Published: February 2024

Objectives

This research aims to explore the perceptions of nursing students and directors of bachelor of nursing degree courses regarding reasons for attrition amongst nursing students.

Methods

A qualitative descriptive study was conducted using inductive thematic analysis. The study included a purposeful sample of 12 students and 4 directors of bachelor of nursing degree courses.

Results

As reasons for attrition, the directors highlighted a lack of preparation for nursing studies and students’ limited awareness of possibilities for support and learning. The students emphasized insufficient support from academic staff and poor course organization. Economic and family issues and a misunderstanding of the professional role of a nurse were cited as reasons by both directors and students.

Conclusions

The findings provide important insight into attrition in the nursing programme. Further research is warranted, particularly in other contexts. Addressing student attrition requires a comprehensive approach that includes the provision of adequate support systems, mentorship, and resources for students.

Discussing the Formal Components of Material Objects: A New Reply to Bennett
Authors: Solís Adrián
Published: February 2024

Recently mereological hylomorphism, the theory in which form and matter are considered to be proper parts of objects, has become very important among contemporary metaphysicians. The present work aims to analyse and dismantle Bennett’s criticism regarding the existence of formal proper parts. To do this, I will start by presenting Koslicki’s mereological hylomorphism. Next, I will focus on Bennett’s critique which seeks to deny the existence of formal proper parts. Finally, I will analyse critically the Bennett’s criticism focusing on the scenario of lump of clay and statue. I will show Bennett’s proposal is not explanatorily better than Koslicki’s hylomorphism because she needs to accept a counter-intuitive thesis. Therefore, we should prefer Koslicki’s mereological hylomorphism.
Intrapericardial nonfunctional paraganglioma: a case report and literature review
Authors: Fan Yuhong , Hu Jiayin , Li Tao , Fang Jingqin
Published: February 2024

Objectives

Paraganglioma (PGL) is a rare extra-adrenal neuroendocrine tumor, and intrapericardial PGL is extremely rare. We report a rare case of intrapericardial nonfunctional PGL, which may be used as a reference for further analysis.

Case presentation

This article presents the case of a 65-year-old woman with a 2-year history of lower extremity pain. Ultrasound revealed a hypoechoic mass adjacent to the right atrium, compressing and narrowing the right atrium. Computed tomography (CT) showed a low-density mass with marked enhancement suggestive of a solitary fibrous tumor or a vasogenic tumor of pericardial origin. Cardiac magnetic resonance imaging (MRI) confirmed the location and provided a primary diagnosis of solitary fibrous tumor, hemangioma, or hemangiosarcoma. The patient eventually underwent pericardial tumor resection, and the diagnosis of PGL was confirmed by postoperative histopathology.

Conclusions

Pathology is considered the gold standard for the diagnosis of PGL. Imaging examinations can provide valuable information for the diagnosis and management of intrapericardial PGL, and surgery remains the treatment of choice.
Parametric analysis of thermal cycle of a short take-off and vertical landing engine
Authors: Mo Zhihan , Zhou Dengji , Shen Xun
Published: February 2024

Short take-off/vertical landing (STOVL) engine is an emerging power source for fighter planes that can perform takeoff and landing operations in tight quarters. As the aforementioned function requires specific component design and matching, it is vitally necessary to study the impacts of various component states on engine performance and stability. This paper develops a performance model for STOVL engines based on nonlinear component models and validates the modelʼs correctness. Variable component working conditions and settings are altered, engine performance is forecasted and observed, and the mechanism underlying this trend is investigated. The results indicate that the performance of the STOVL engine is greatly influenced by the design parameters of the gas path, such as the bypass ratio and the injection volume of the roll nozzle, and is highly dependent on the correct adjustment of the rear bypass injector and the throat area of the nozzle.
Numerical investigation on mixing of heated confined swirling coaxial jets with blockage
Authors: Srivastava Ritesh , Patel Vivek Kumar
Published: February 2024

A coaxial jet that has one application in gas turbine combustion chambers where there is a requirement for very good mixing of air and fuel for complete and stable combustion. A study has been carried out to improve the mixing of annular and central jets in the confined space of the combustor. The combustor model is used with two confined coaxial air-swirling jets under non-combustion conditions. The influence of a heated central jet and the effect of blockage at different locations in confined spaces on mixing has been studied. To understand mixing in jets in confinement, the center line axial velocity profile and streamlines have been presented at different locations. The computational results are obtained using commercial CFD software, ANSYS FLUENT 18.0, with a standard k–ω turbulence model. After validation with the existing literature, parametric studies have been carried out with co-swirl and counter-swirl conditions of annular and central jets at different blockage locations in confinement. The results show a good understanding of the mixing process of two jets in confinement.
Clausal doubling and verum marking in Spanish
Authors: Muñoz Pérez Carlos , Verdecchia Matías
Published: February 2024

This paper offers a description and analysis of the clausal doubling construction, and contrasts it with predicate doubling based on their formal and verum-related properties. The study shows that the behavior of both patterns can be captured by extending the analysis of predicate doubling by Muñoz Pérez and Verdecchia (2022. Predicate doubling in Spanish: On how discourse may mimic syntactic movement. Natural Language & Linguistic Theory 40(4). 1159–1200). Basically, both doubling constructions have the same structure, with a contrastive topic in the left periphery; they differ, however, in the nature of the constituents carrying this function. The proposal derives from this single factor all formal and interpretative differences between the constructions. Moreover, the paper provides evidence to distinguish these phenomena from other verum-marking strategies in Spanish.

Published: February 2024

In this paper we investigate how verum is realized in Xhosa and Zulu, two Southern Bantu languages belonging to the Nguni group. The data for our study were collected through interviews with native speakers who were prompted to produce sentences in discourse contexts that typically license utterances with verum. We found that the main grammatical strategy for the expression of verum in Xhosa and Zulu involves the removal of phrasal constituents from the focus domain (the VP). This leaves the verb as the sole remaining focus host, and allows auxiliary features of the verb, such as polarity, to be marked as focus. Consequently, we analyse verum in Xhosa and Zulu as polarity focus, which is expressed indirectly, via the backgrounding of potentially focusable phrasal material. We also examined the prosodic properties of verum utterances in Xhosa. Based on findings from previous studies on Nguni intonation, we expected to observe lengthening of the penultimate vowels of phrase-final verbs and utterance-final words in our data. However, contrary to expectation, we did not find evidence of penultimate vowel lengthening in Xhosa sentences with verum, a (preliminary) result which suggests that the expression of verum may have an effect on prosody in Nguni languages.

A medencefenék tréning első-vonalbeli kezelés a vizelet inkontinencia kezelésében. Jelenleg elegendő bizonyíték van arra, hogy a rendszeres medencefenékizom-tréning javítja az inkontinenciát, azonban kevés magas minőségű tanulmány van, amely alátámasztaná, hogy a hatékony medencefenékizom-tréning eléréséhez szükséges és nélkülözhetetlen a mély hasizmok erősítése. A kutatás célkitűzése, hogy egy komplex megközelítést adjon az inkontinencia kezeléséhez, egy alternatív módszer, a Callanetics® torna mély izmok aktiválása és a komplex gátizomtorna, az erőteljes légzéstechnika és a vízszintes és függőleges tréninghelyzet alkalmazása révén hatást gyakorolva a medencefenék erejére. Az egészséges és inkontinens szült és nem szült nők körében vizsgáltuk a testtartás és a vizeletinkontinencia változását tréning hatására, a gátizom kondicionális képességeinek felületi hüvelyi EMG és a musculus transversus abdominis vastagságának ultrahang mérésén keresztül. A 20 hetes Callanetics® torna hatására csökkentek az inkontinenciás tünetek, mind a gyors, mind a megtartó gátizom funkció javult, a gátizom gyakorlatokkal kombinált Callanetics® torna hatásosabb a gátizmok erejének növelésében és formálta az alakot is. A 8 hetes Gátizomtorna erőteljes kilégzés technikával alkalmazva hatékonyan javította az inkontinenciát, a gátizom tartási funkciójának javulása mind fekvő, mind ülő helyzetben szignifikáns volt, de a gyors reakciójának javulása csak fekvő helyzetben, míg a gátizom nyugalmi funkciójának javulása csak ülő helyzetben volt szignifikáns. Tanulmányunk alapján arra jutottunk, hogy mindkét program hatékony és hasznos elemeket foglal magába, de mindenképpen nélkülözhetetlen az egyén pontos állapotfelmérése mind a testtartás, mind a gátizom funkciói, diszfunkciói és motiváltsága szempontjából.

Published: February 2024

Background:

Shanghai and Hong Kong, China, experienced an outbreak of COVID-19 in early 2022. Both cities had similar dynamic prevention policies and population-level immunity, but showed differences in the numbers of cases and deaths.

Methods:

We collected data from official websites to estimate and compare the infection rates, mortality rates, and infection fatality ratios (IFRs) between cities. We further performed univariable analysis and used two tree models to explore the factors affecting the differences.

Results:

The infection rate in Hong Kong, China, was 42.45 (95% CI: 42.41–42.48) per 100 individuals (15.49 times higher than that in Shanghai). The mortality rate was 124.90 (95% CI: 122.33–127.46) per 100,000 individuals (51.61 times higher than that in Shanghai). The adjusted IFR was 0.29% (95% CI: 0.29–0.30%) (3.30 times higher than that in Shanghai). The infection rate was negatively correlated with the stringency of nonpharmaceutical interventions. The mortality rate and IFR negatively correlated with the vaccination rate. However, positive correlations were observed between the median age and both mortality and IFR, as well as between the proportion of people ≥65 and IFR.

Conclusions:

Overall, a lack of medical resources, lower vaccination rates, and higher median age were associated with a higher infection rate, mortality rate, and IFR in Hong Kong.

Bu çalışmada 3 farklı ilden (Aksaray, Niğde ve Konya) toplanan 18 adet geleneksel ekşi hamur örneğinden Saccharomyces cerevisiae suşlarının izolasyonu, farklı DNA markörleri ile genotipik karakterizasyonu ve popülasyon analizlerinin gerçekleştirilmesi amaçlanmıştır. İzole edilen 72 adet endojen mayanın 58 tanesi S. cerevisiae olarak tanımlanmıştır. Tür içi genetik varyasyonun belirlenmesinde SCoT 13 primeri, iPBS ve ISSR primerlerine göre daha faydalı sonuçlar vermiştir. Popülasyonlar arasındaki mesafe arttıkça genetik uzaklık dereceleri de artış göstermiştir (R=0.74). Popülasyonlar arası (%16) ve popülasyonlar içindeki (%84) genetik varyasyon dereceleri istatistiki olarak önemli bulunmuştur (P < 0.001). UPGMA dendrogramı üzerinde suşlar birçok alt gruba ayrılmış olup STRUCTURE analizine göre anlamlı alt grup sayısı iki çıkmıştır (ΔK=2). UPGMA ve PCoA'ya göre kümelenme suşların izole edildiği bölgelere göre gerçekleşmemiş olup rastgele dağılım gözlemlenmiştir.
Does Age Buffer or Exacerbate the Impact of Sadness and Anger on Romantic Relationships?
Authors: Munin Shaina , Neff Lisa A. , Beer Jennifer S.
Published: February 2024

Expressions of sadness and anger during a romantic relationship conflict can have distinct impacts on partners’ feelings of closeness and perceptions of conflict resolution. For example, previous research with younger couples suggests that expressions of sadness can help partners feel closer to one another, while expressions of anger tend to harm closeness and short-term conflict resolution. However, research has not considered whether older couples differ in their responses to sadness and anger expression during conflict, despite different theories of aging which suggest that older adults may be better or worse at regulating negative emotion in their relationships than younger adults. The current study (N = 280 dating and married couples, 30-88 years old) tested whether age buffers or exacerbates the effects of observed emotional expression (sadness or anger) on partners’ perceptions of closeness and conflict resolution. Contrary to the pre-registered hypotheses derived from theories of aging and emotion, no significant age differences in partners’ responses to sadness or anger expressions emerged. Expressions of sadness were also not significantly related to perceptions of closeness or conflict resolution. However, consistent with previous research, expressions of anger negatively related to both partners’ perceptions of closeness and conflict resolution. The present findings extend previous research by testing whether expressions of sadness and anger have distinct impacts at multiple stages of the lifespan. Additionally, the non-significant age differences contribute to a growing literature which identifies contexts where age differences in responses to negative emotional expression may be less likely to emerge.

The paper explores chapter books, explaining their nature and providing information on their usefulness and possible uses in the context of teaching English as a foreign language. It outlines their properties, layout and subject matter. The goal of the exploratory study was to investigate whether young Croatian pupils could read English chapter books written for native speakers and whether illustrations helped them to comprehend the narrative. Furthermore, it aimed to examine pupils’ response to the format of chapter books. The study about the suitability of chapter books was conducted among pupils in the third, fourth and fifth grade in two Croatian schools, and its results show that young learners of English as a foreign language can grasp the essence of a story and can reflect on what they read, identify points of difficulty and the strategies applied. The findings suggest that carefully chosen chapter books can be valuable authentic materials in aiding language acquisition, fostering discussions, and engaging higher-order thinking skills in young EFL learners in Croatia.
Modeli istraživanja procesa prijelaza djeteta iz predškolske ustavnove u osnovnu školu
Authors: Miočić Marijana
Published: February 2024

Djetetov prijelaz iz predškolske ustanove u osnovnu školu važno je pedagoško pitanje. O kvaliteti i primjerenom uključivanju djeteta u prvi razred osnovne škole raspravljalo se na mnogim svjetskim skupovima u organizaciji različitih međunarodnih organizacija. Na sjednici UNESCO-a održanoj 2010. godine istaknuto je kako se odgojno-obrazovni sustavi razlikuju prema posebnosti kulturnog konteksta kojem pripadaju, što pretpostavlja i različit pristup prijelaza djeteta iz jednog odgojno-obrazovnog konteksta u drugi. Velik utjecaj na tijek odvijanja procesa prijelaza ima obrazovna politika, stoga je tema prijelaza djeteta iz predškolske ustanove u osnovnu školu u Republici Hrvatskoj vrlo važna u provedbi kurikulnih promjena. U radu će se dati presjek dosadašnjih istraživanja procesa prijelaza djeteta iz predškolskog odgojno-obrazovnog konteksta u kontekst prvog razreda osnovne škole u pojedinim zemljama Europe i svijeta (SAD, Australija) te u Republici Hrvatskoj. Na temelju dobivenih podataka utvrdit će se postoji li odgojno-obrazovni kontinuitet na dobrobit pojedinog djeteta.

Benign tumors of the chest wall are rare. Aneurysmal bone cyst is a benign tumor of the skeleton system which mainly develops at the level of the long bones and the vertebrae, and rarely at the rib level. We present a case of a 17-year-old young female with no medical history who presents a mass at the right basal level of the chest wall. The CT scan shows a multiloculated mass at the level of the twelfth ribs, by an elective incision the tumor was resected. The histology was in favor of an aneurysmal bone cyst.

Published: February 2024

The quest to reduce global plastic consumption has led to the emergence of biodegradable fiber-based composites as a promising sustainable replacement to conventional plastics in the food packaging industry. As the packaging sector is shifting more towards fiber-centric materials, thermoforming techniques for the 3D forming of the fiber-based materials, especially using complex mold designs, should be thoroughly researched to replace the conventional plastics in the industry. Finite element analysis of the deformation behavior of the paperboard during the thermoforming process and the factors that trigger the fracture of the composite layers were studied in the present work. The results show that 90° fiber orientation, 0.3 mm sheet thicknesses, and specific mold geometries can result in better forming results, thereby maximizing the potential of fiber-based materials in thermoforming.
