Authors: Hadi Syaiful , Sa’dijah Cholis , Sudirman Sudirman , Sulandra I Made , Rahayuningsih Sri
Published: March 2024

Spontaneous problem posing is a basic concept of spontaneous mathematical thinking and science learning. Students generate problems without systematic encouragement and pose problems based on the student's desire to develop their skills. As a result, they can serve as important markers of constructive mathematical and science engagement, particularly affective engagement, for problem solvers and their classroom communities. We used a qualitative approach to analyze student characteristics, especially in the affective domain, when presenting random problems. We used an observational approach and experience sampling in each class to observe students' engagement in spontaneous problem posing both individually and in groups. The findings revealed that each student showed different characteristics when presenting problems suddenly (spontaneous problem posing). The submission of the first subject problem was categorized as problem-as-exercise, satisfying the characteristics of spontaneous originality, where constructive emotional experiences impressed more on the teacher, while negative emotional experiences impressed more on oneself (self), classmates, and mathematical activities. The submission of the second subject problem is classified as a problematic problem, fulfilling the characteristics of spontaneous originality. Negative emotional experiences are more visible in me (myself), while constructive emotional experiences are more visible in teachers, classmates, and math activities

Challenges in geometric modelling–A comparison of students’ mathematization with real objects, photos, and 3D models
Authors: Jablonski Simone
Published: March 2024

Mathematical modelling aims at contributing to the involvement of reality in mathematics education. As an example, geometric modelling can be implemented by the use of real objects in modelling tasks. Still, (geometric) modelling tasks can be a challenge for students, especially in the transfer from reality to mathematics, which is referred to as mathematization. Since the representation of a real object in tasks might differ, the question arises, which challenges can be observed when working in different task settings. In a study with 19 secondary school students, the task settings (1) outdoors at the real object, (2) indoors with photos of the real object, and (3) indoors with a 3D model of the real object are compared. Based on video recordings, differences concerning the students’ challenges are examined. The results highlight challenges in estimating and measuring when working at the real object, scale and perspective when working with photos and the transfer between representation and object when working with 3D models.
Toleration of Sex Work in East-Central Indiana, 1880–1900
Authors: Desilva Jennifer Mara , McGuire Emily K. , Balkenbusch Cory
Published: March 2024

ABSTRACT: From 1880 through the gas boom period (1887– 1900), several east-central Indiana towns and small cities hosted thriving brothel scenes. Toleration existed alongside campaigns to arrest and fine sex workers and their clients. Newspapers played an important role in the toleration dynamic, narrating efforts to regulate and suppress sex work, while cultivating public knowledge about sex workers and brothel locations. Exploring reportage of sex work and the municipal preference for fines over expulsion, trends emerge of the careers and migration of sex workers. In contrast to the 1858 prediction of New York City physician William Sanger that sex-worker careers lasted only a few years, newspapers reveal some women working for over a decade. Long careers signal toleration, which undermines the traditional narrative of gender-ratio imbalance prompting the arrival of sex workers in boom-towns. Mapping brothels and arrests in Muncie, Kokomo, and Elwood, Indiana, also challenges the existence of a single vice district in each city, revealing the integration of sex workers into the urban fabric.

KÜLTÜREL ŞEMA TEORİSİ DOĞRULTUSUNDA ÇEVİRMEN HABİTUSUNA BİR BAKIŞ
Authors: ÖZYURT Sebahat Burcu Irmak
Published: March 2024

Çeviribilim 1970’lerden sonra yeni bir uluslararası ve disiplinlerarası akademik alan olarak ortaya çıkmıştır. Çeviribilimin disiplinlerarası doğası nedeniyle bu alanda çeviri sürecine ilişkin birçok gelişme gözlemlenmektedir. Çeviribilimin yararlandığı bilim dalları arasında göstergebilim, dilbilim, dil felsefesi, kültür sosyolojisi, edebiyatbilim, sözlükbilgisi, terminoloji, uzmanlık dili araştırmaları, bilgi yönetimi, eğitim bilimleri, psikoloji ve iletişimbilim yer almaktadır ve çeviribilim bu bilim dallarıyla etkileşim içinde bulunmaktadır. Bu bağlamda “kültür şeması” ve “habitus” gibi ayrı disiplinlere ait iki kavram farklılıklarına rağmen çevirmenin bilgi birikimi çerçevesinde çeviribilim alanında ortak bir paydada yer alabilmektedir. Kültürel şema teorisi; felsefe, psikoloji, sosyoloji, antropoloji gibi disiplinlerde kullanılan bir kavramdır. İlk olarak 1930'larda ortaya çıkmış olan Şema kavramı 1970 ve 1980'lerde hem bilişsel psikoloji hem de bilişsel bilimdeki gelişmelerin önem kazanmasıyla daha çok fark edilmiştir. Bourdiou’nün ortaya koyduğu habitus ise sosyolojide ortaya çıkmış ve sonrasında birçok alanın yanı sıra çeviribilimde de yer bulmuş bir kavramdır. Bu ifade, bir kişinin yetiştirilmesi, eğitimi, deneyimleri ve kültürel geçmişinin bir sonucu olarak gelişen rutinlerini, düşünce biçimlerini ve eylemleri ifade eder. Bourdieu'ya göre bir kişinin habitusu, dünya görüşü, dili, değerleri ve davranışları üzerinde etkisi olan bilinçaltında kültürel olarak oluşturulmuş yapılardır. Çeviri bağlamında bir çevirmenin habitusu, çeviri sırasında çevirmenin kendi kültürel, dilsel ve deneyimsel geçmişinin etkisini ifade eder. Bir çevirmenin çeviri sürecinde aldığı kararlar, terim seçimi, ifade biçimleri ve anlam aktarımı da dâhil olmak üzere, alışkanlıklarından etkilenebilir. Çevirmenler kendi alışkanlıklarını ve kültürel geçmişlerini anlayarak çalışarak daha iyi çeviriler üretebilirler. Bir kişinin kültürel şeması ve habitusu arasındaki benzerlik çok dikkat çekici olsa da aralarında bazı farklılıklar da bulunmaktadır. Bir kişinin kültürel şeması ile habitusu hakkında bilgi sahibi olmak o kişi ile daha etkili ve kültürel olarak duyarlı bir şekilde etkileşimde bulunmamızı sağlar. Bir çevirmenin kendi kültürel şemasına ve habitusu hakkında bilgi sahibi olması da benzer şekilde; o çevirmenin ortaya çıkardığı çevirilerin daha başarılı olmasını sağlar. Bu çalışmanın amacı, çevirmenin habitusunun kültürel şema teorisi doğrultusunda kaynak taraması yöntemi ile araştırılıp çeviribilim alanında benzerliklerinin ve farklılıklarının ortaya koyulmasıdır.

Published: March 2024

The composition, properties, voltammetry studies and morphology of electrodeposited Zn-Fe alloy deposits obtained from an alkaline sulphate bath containing tartrate have been investigated. A bath containing high percentage of iron (20% wt.) produced an alloy with less percentage of iron (12% wt.) i.e. anomalous co-deposition process. The percentage of iron in an alloy decreased with temperature of the plating bath and thickness of the alloy deposit. The cathodic current efficiency depends on plating variables. Cyclic voltammetry studies indicate the mutual co-deposition of zinc with iron. Zn-Fe alloy showed a superior corrosion resistance than zinc coatings. Hardness of the alloy deposits increased with increase in iron content in the alloy. Smooth, uniform and fine grained deposits were obtained for the Zn-Fe alloy containing 20% Fe.

The composition, properties and morphology of electrodeposited Zn-Ni alloy from an alkaline sulphate bath containing triethanolamine (TEA) and mercaptopyridine (MPY) have been investigated. A bath solution containing 3.5% wt. Ni content produced an alloy deposit with 12.5% wt. Ni (more noble metal) indicating preferential deposition of nickel (i.e. Regular co-deposition process). With increase in current density and the concentration of TEA, the percentage of nickel in the alloy deposit decreased. An increase in temperature, thickness and the concentration of MPY increases the percentage of nickel (more noble) in the Zn-Ni alloy deposit. CCE was decreased with current density, increased with temperature and stirring of the bath solution. Static potentials of Zn-Ni alloy were less noble to nickel and more noble to zinc. Hardness of the alloy increased with an increase in %Ni in an alloy. Fine grained deposits were observed morphologically.

The modern, dynamic world can’t imagine its development without carrying the concept of advancement in composite materials. Various researches are going on in this field to achieve the desired standard. Natural fiber reinforced polymer composite (NFPC) has a huge affinity to interchange the composite made up of synthetic fiber. This is primarily because of the advantages like light-weight, non-toxic, nonabrasive, easy availability, low cost and biodegradable properties. The specific mechanical properties like specific tensile modulus and other specific properties of natural fiber gives a satisfying result for composites as compared to synthetic fiber based composites. The general objective of this work was to develop a composite from bamboo fibers and HDPE reinforced with red bauxite mud residues to ensure good thermal stability and improve the physico-mechanical properties in traction and flexion. The morphology of the composites showed that there was a homogenous dispersion of BF at lower weight fraction, although ﬁbre agglomeration was noticed at higher weight fraction. The results of this study revealed that treated bamboo ﬁbres are suitable for reinforcing HDPE. It appears from these studies that the formulations produced are in accordance with the ASTM standard and can validly be used for the thermal comfort of buildings to improve the comfort of the population in sustainable habitats.

The synthesized SeNPs were characterized by UV-Vis Spectroscopy and exhibited a peak at 264 nm and 265 nm for Gr- SeNPs and Ch-SeNPs; XRD, EDX revealed the atom percentage at 89.07% for Gr-SeNPs and for Ch-SeNPs at 78.45%. The electron microscopy results revealed that synthesized SeNPs morphology was spherical in shape. XRD reports explain the sharp peaks indicate the crystallinity of the nanoparticles the crystalline size of Gr-SeNPs and Ch-SeNPs are 32.13 nm and 33.41 nm. FT-IR spectrum results describe the information about the interaction between functional groups of phytochemicals in the leaf extract and the SeNPs. This study also proved the antibacterial potential of green SeNPs against common fish pathogens comparable to chemical SeNPs. Based on these results, it is confirmed that leaf extract capped SeNPs may have potential bio-medicinal applications when compared to chemical synthesized SeNPs.

Nanostructured Al doped Tin Oxide (ATO) thin films were deposited on cleaned glass substrate by spray pyrolysis technique at 400 °C using a solution consisting of SnCl4 starting as material and doping source AlCl3 which were dissolved in methanol and stirred four hours. The effect of changes in doping source content of Al:SnO2 thin films were investigated and studied the crystalline structure, surface morphology, transmittance and optical band gap of ATO films. The dopant concentration varied from 0 to 10%. X ray diffraction studies conformed the proper phase formation in the films are polycrystalline without any second phase with preferential orientations along the (110), (200), and (211) planes and an average grain size of 20 nm. The visible transmittance exceeds 85% and the optical band gap was estimated to be around 2.6 eV to 3.6 eV. The scanning electron microscopic (SEM) studies showed the particle size lying in the range 20 nm for undoped films and it is decreasing while increasing of Al doping.

Los noviazgos en la Salónica sefardí de entre finales del siglo XIX y principios del XX
Authors: Romero Elena
Published: March 2024

En el presente artículo se aborda un tema hasta ahora poco tratado: los noviazgos en el mundo sefardí del Imperio otomano y cómo afectaba el proceso al entramado familiar. Para la exposición se usan diez textos –8 en prosa y 2 en verso–, todos ellos escritos por varones, en los que se muestran las visiones contrapuestas de los padres de familia y de los jóvenes casaderos. Los textos aparecieron en el periódico de Salónica La Época entre 1889 y 1908. Serán tales textos los que de una forma cercana a su realidad ambiente nos transmitan lo que al respecto sucedía en aquellas comunidades sefardíes hoy desaparecidas.
Midiendo el «progreso» humano en el Nuevo Milenio: la Cuestión Judía revisitada
Authors: Lempert David
Published: March 2024

Este artículo consta de dos partes. En la primera parte se ofrece un nuevo enfoque sobre el progresismo y las políticas progresistas mediante la definición de diversas tipologías de progresismo y buscando estas aproximaciones en las estrategias culturales de grupos étnicos específicos. Este trabajo teoriza sobre la forma en que estas estrategias se mantienen y las distingue del «progreso» aparente que puede ser simplemente un fenómeno efímero de adaptación de dichos grupos étnicos en sistemas más complejos. En la segunda parte se examina la ideología del «progreso» como componente en la estrategia cultural de los judíos y si esta estrategia, que se muestra más fuerte cuando los judíos son minorías en diáspora, es coherente con la cultura judía una vez los judíos han conseguido un límite territorial en el que son ya «mayoría». Este artículo alude a las opciones políticas que los judíos «políticamente progresistas» y los judíos, en general, han tomado recientemente en los Estados Unidos de América; modificando su apoyo al «progreso» a cambio de más representación política de forma paralela a las situaciones históricas de otras minorías. Aunque la opción política «basada en la identidad» que ha ralentizado el «progreso» general de la civilización parece haber protegido los intereses judíos a corto plazo, las comparaciones históricas sugieren que esta elección puede poner en peligro a los judíos si la economía estadounidense y su influencia mundial se colapsan, de manera paralela a lo que ocurrió durante el Holocausto europeo; ofreciendo una oportunidad para poner a prueba las teorías sobre cómo (y si) se produce un «progreso». En resumen, este estudio examina las elecciones tomadas por los judíos durante el siglo xx para definirse a sí mismos como «europeos» en vez de «orientales de Levante» (o «del Este») y como un replanteamiento de esta elección podría ser fundamental para la protección de los judíos en Israel reiniciando de manera global el «progreso» tanto a nivel social como político.
Sobre Ḥikāyat al-Ḥūb wa-l-Waṭan, la versión judeo-árabe de ‘Amor en Sion’ de Abraham Mapu. Estudio preliminar
Authors: Garcia Arevalo Tania María
Published: March 2024

La considerada como primera novela de la literatura hebrea moderna, Ahabat Ṣion o ‘Amor en Sion’ de Abraham Mapu, ha sido una de las obras más traducidas a otras lenguas desde su publicación en 1853. Sin embargo, merecen especial consideración aquellas versiones judeo-árabes surgidas a la luz de la Haskalah o Ilustración judía en el área del norte de África, en concreto, Túnez y las ciudades de su periferia. De entre todas, este artículo tiene como objetivo enfocar sus páginas en la titulada Ḥikāyat al-Ḥūb wa-l-Waṭan ‘Novela del amor y de la patria’ (Susa, 1943), por tratarse de la última de todas ellas surgida en los años de declive del movimiento de publicaciones en judeo-árabe a mediados del siglo xx y por conformarse como el segundo intento de traducción de Messud Ma’arek, uno de los impulsores y editores más destacados de publicaciones en judeo-árabe en la etapa moderna. El estudio preliminar que se plantea tiene como objetivo contextualizar esta traducción, ofrecer una descripción de la grafía que presenta y una comparación entre Ḥikāyat al-Ḥūb wa-l-Waṭan y la original Ahabat Sion a través de ejemplos textuales.
Expresiones judeoespañolas en los relatos de vida de supervivientes griegos de la Shoa
Authors: Pinto-Abecasis Nina
Published: March 2024

¿Qué papel juegan las expresiones judeoespañolas en los relatos de vida escritos por supervivientes ladinoparlantes de la Shoa? ¿En qué medida determinan la lengua y las expresiones judeoespañolas el centro de gravedad de los relatos? ¿Y por qué escogen los narradores incorporar expresiones judeoespañolas en el contexto de la lengua hebrea en la que escriben sus relatos? Éstas son algunas de las cuestiones principales tratadas en este artículo que presenta la hipótesis de que el objetivo de la incorporación del judeoespañol a los relatos en hebreo es otorgarles una mayor fuerza y hacer la experiencia judeoespañola más accesible a quienes no forman parte de ella. Es interesante señalar que es precisamente el hecho de que el judeoespañol fuese una lengua minoritaria en los campos de exterminio lo que proporciona una fuerza particular a sus hablantes, supervivientes de la Shoa, a la hora de componer sus relatos. El judeoespañol conservado en el recuerdo de esos supervivientes, que se convirtió en una ‘lengua informal’ en los campos, adquiere una nueva vitalidad en sus relatos. Centramos la discusión en las autobiografías de supervivientes griegos y en testimonios recogidos en entrevistas con estos supervivientes. En todos ellos examinamos la incorporación de expresiones judeoespañolas a los relatos y las referencias al estatuto de la lengua judeoespañola durante la Shoa.
Culturas judías de la diáspora sefardí – diálogos sobre judaísmo entre judíos que retornaban a «tierras de idolatría» y criptojudíos hispánicos
Authors: Moreno Goldschmidt Aliza
Published: March 2024

Una de las características de la diáspora sefaradí del siglo XVII fue su gran movilidad geográfica. Entre los fenómenos menos estudiados en este contexto encontramos varios casos de individuos que regresaron a España, o sus colonias americanas, tras haber residido cierto período de tiempo en alguna de las comunidades judías de la diáspora sefaradí. Tras su regreso a tierras de idolatría, muchos de ellos llegaron a mantener estrechas relaciones e interesantes intercambios culturales con cristianos nuevos de origen judío que nunca habían salido de los límites de los reinos ibéricos y por lo tanto no habían mantenido ningún encuentro directo con el judaísmo. El presente artículo estudia este tipo de encuentros y analiza los distintos diálogos interculturales entre estos dos mundos tan cercanos y tan lejanos a la vez.

El asentamiento de «El Castil de los Judíos» (Molina de Aragón, Guadalajara)
Authors: Arenas Esteban Jesús A.
Published: March 2024

En el presente trabajo se aborda el análisis del edificio identificado como una sinagoga en el asentamiento hispano-judío de «El Castil de los Judíos» de Molina de Aragón, en la provincia de Guadalajara.En primer lugar, se realiza un examen tanto de su configuración arquitectónica como de sus elementos decorativos internos, lo que conduce a una propuesta de reconstrucción volumétrica. Seguidamente se valora la relación que este espacio pudo mantener con un edificio de grandes dimensiones adyacente, proponiendo la posible existencia de un complejo urbano de significado religioso compuesto por varias estructuras de diferente fisonomía y funcionalidad.Muchos de estos aspectos deben ser considerados hipotéticos porque lo fragmentario de los restos no permite emitir juicios categóricos. No obstante, la similitud de algunos elementos documentados las sinagogas de Molina y Lorca podrían estar indicando una distribución interna en cierto modo normalizada, que en el caso de otras sinagogas medievales —como los toledanas de El Tránsito y Santa María la Blanca o la de Córdoba— habría desaparecido tras su conversión en templos cristianos.
La sinagoga bajomedieval de Lorca: balance de 15 años de investigaciones y nuevas perspectivas
Authors: Eiroa Rodríguez Jorge A. , Gallardo Carrillo Juan , González Ballesteros José A.
Published: March 2024

El descubrimiento de una sinagoga bajomedieval en el interior del castillo de Lorca (Murcia) supuso una de las principales referencias arqueológicas en el estudio de la religiosidad de las comunidades judías medievales hispánicas de los últimos años. Su buen estado de conservación, desde una perspectiva arqueológica, y el hecho de que no hubiese sido transformada en iglesia con posterioridad, permitieron identificar con claridad los elementos más significativos que caracterizaban a este tipo de edificios religiosos. Los diversos trabajos de investigación realizados desde entonces han puesto de relieve distintos aspectos sobre cada una de sus partes. Este breve estudio se centra en los nuevos datos obtenidos durante la última fase de actuaciones llevadas a cabo entre 2010 y 2012.
