Published: April 2023

There has been growing interest in the study of extensive reading in this decade, especially in the area of students' responses by using mobile-assisted language learning (MALL). However, of those studies, only a few explored the effects of assisted learning from the students' internal lens. To fill the gap, this study investigates the students' perceptions of implementing extensive reading through mobile-assisted language learning (MALL) during the Covid-19 pandemic viewed from an internal perspective. The subjects were students' batch 2019 at English Language Study Program at Lambung Mangkurat University. The researchers used purposive sampling to select 20 students based on specific criteria. The study used a qualitative approach that focused on a case study. The instruments were semi-structured interviews. The interview data were interpreted in narration. Based on the findings, students positively perceive implementing extensive reading through MALL during the Covid-19 pandemic. It was discovered four themes involve enhancement of self-students motivations, encouragement of students' feelings, fulfilling their language needs, and reflecting students' perspectives. This study calls for the inclusion of students to read extensively using mobile devices as a good learning strategy to improve their Language skills. However, they must find ways to overcome the challenges

Published: April 2023

This article describes the results of research on ECE teachers regarding their understanding of the creative play. Creative play in early childhood education is defined as play-based learning that combines creativity and higher-order thinking skills to stimulate aspects of development in the context of constructing children's attitudes, knowledge, and skills in this millennial era. This creative play-based learning is known as HOTS learning for early childhood. This research was carried out in a survey by filling out a Google Form which was distributed through several WhatsApp groups. 400 respondents contributed to sending answers and were analyzed using the Excel application to find out the tendency of ECE teachers to understand the creative play. The results of this study found that ECE teachers tend not to understand creative play in early childhood. They tend to design play activities that are separate, not intact, and still at the C2 level in the cognitive realm.

The Exploitation of Women's Body and Sensuality: The Attraction of Newspaper Movie Advertisements in Local Daily Newspapers
Authors: Hati Lila Pelita , Ginting Lestari Dara Cinta Utami , Malik Rahman
Published: April 2023

Newspaper advertising experienced a significant increase in the 1970s. During that period, three local daily newspapers were established in Medan, namely: Waspada, Sinar Indonesia Baru, and dan Analisa. These newspapers displayed various advertisements in their publications; one of which was the advertisement to promote the film that would be shown in theaters at that time. In promoting films through these advertisements, many producers women as a means of promotion. Women seemed to have their magnet to attract the audience's interest. This journal explains how the women’s representation in the local daily newspaper advertisements in Medan in the 1970s, and how the exploitation of women’s bodies and sexual attractiveness in the advertisements for the promotion of the film was related to global discourse, especially in terms of women's appearance. The four stages of historical methods are applied to conduct the research, namely heuristics, verification, interpretation, and historiography. The results of the research show that advertising producers often showcased pictures of beautiful and sexy women and even displayed vulgar words to attract the audience's interest which didn’t represent the storyline of the film itself.
Residents’ support for tourism development: Investigating quality-of-life, community commitment, and communication
Authors: Yayla Özgür , Koç Burcu , Dimanche Frederic
Published: April 2023

This study argues that when overall tourism impacts are positive, residents’ quality of life (QOL) increases, thereby positively affecting their attitudes towards tourism initiatives. The study also identifies several other important relationships that have been ignored in the literature. First, QOL may be a crucial push factor for community commitment, which in turn can trigger support for additional tourism development. Second, communication with tourists may moderate the links between QOL, community commitment, and tourism support. Data were collected from 468 residents living in Manavgat, Turkey and analyzed using structural equation modeling and Hayes’s PROCESS macro. The findings show that as the perception of the positive effects of tourism increases, opinions about the QOL will also be optimistic. Importantly, QOL strengthens both tourism support and community commitment. Additionally, community commitment mediates the link between QOL and attitudes towards tourism development. Finally, community commitment increases support for tourism, which is stronger for residents who communicate more with tourists.

Sîbeveyhi (ö. 180/796), Basra dil okulu öncülerinden olup günümüze ulaşan Arap dil gramerine dair yazılmış ilk hacimli eser olan el-Kitâb’ın yazarıdır. Sîbeveyhi, bu eserinde kendi görüşlerinin yanı sıra başta hocası Halîl b. Ahmed (ö. 175/791) ve Yûnus b. Habîb (ö. 182/798) olmak üzere dönemin önemli dilcilerinin görüşlerine yer vermiştir. Ayrıca eserde Sîbeveyhi’nin hem doğrudan hem de hocaları vasıtasıyla Araplardan yaptığı pek çok nakil yer almaktadır. Genç yaşta vefat etmesine rağmen Sîbeveyhi, alanda otorite kabul edilmiş, eseri asırlarca ders kitabı olarak okutulmuş ve alanla ilgili yazılan bütün eserlere doğrudan veya dolaylı olarak kaynaklık etmiştir. Yazıldığı günden günümüze kadar eser ve yazarı üzerine onlarca çalışma yapılmasına rağmen ülkemizde Sîbeveyhi ve el-Kitâb’ı üzerine yeteri kadar çalışma yapılmamıştır.

Erken Dönem Ulûmu’l-Kur’ân Literatüründe Münâsebâtü’l-Kur’ân’ın İzlerine Dair Bir İnceleme: Te’vîlu Müşkili’l-Kur’ân ve el-Akl ve Fehmü’l-Kur’ân Örneği
Authors: KABAKCI Ersin
Published: April 2023

Münâsebâtü’l-Kur’ân, tefsir ilminde ve özellikle de Ulûmul-Kur’ân’da önemli bir husus olarak değerlendirilmektedir. Ayrıca bu ilimle ilgili kayda değer müstakil bir literatürün oluştuğu görülmektedir. Münâsebât ilmini dikkate alan tefsir faaliyetlerinin Zemahşeri ile başladığı, Fahreddin Razi ile sistemleştiği
yönünde bir kanaat bulunmaktadır. Bu ilme yönelik müstakil literatürün ortaya çıkışının ise daha geç dönemlere rastladığı bilinen bir gerçektir. Bu nedenle hicrî altıncı asırdan önce münâsebât meselesine ilişkin bir içeriğin eserlere yansımadığı yönünde yaygın bir düşünce ortaya çıkmıştır. Bu makale, 2020 yılında “Ayetler Arası Münâsebet Meselesinin Tefsirlere Yansımasının Tarihî Kökenine Yönelik Bir Sorgulama: Tefsîru Mukâtil Örneği” adlı makale çalışmamızda ortaya konulan “Mushaf tertibinin bağlayıcılığının münâsebâtı dikkate alan okumaların daha erken dönemlerde başlamasına yol açtığı” hipotezinden hareket etmektedir. Nitekim Tefsîru Mukâtil özelinde yapılan inceleme, münâsebâta dair yorumların tarihinin erken dönem tefsirlere uzandığını göstermektedir. Makale, erken dönem ulûmu’l-Kur’ân literatüründe münâsebât ilminin nüvelerini ve izlerini tespit etmeyi amaçlamaktadır. İlgili literatürün araştırmaya dâhil edilmesi, münâsebâtü’l-Kur’ân’la ilişkili ilimlerin ve konu başlıklarının bulunmasından ileri gelmektedir. Bu kapsamda makalede İbn Kuteybe’nin (ö. 276/889) Te’vîlu Müşkili’l-Kur’ân’ı ve Hâris el-Muhasibi’nin (ö. 243/857) el-Akl ve Fehmü’l-Kur’ân’ı içerikleri bakımından münâsebâtü’l-Kur’ân bağlamında analiz edilmektedir. Söz konusu analizlerde, Zemahşeri ve Razi tefsirleriyle mukayeseli bir yöntem benimsenmektedir. Araştırma neticesinde, erken dönemde münâsebât konusunun gerek “müşkil” meseleler arasında gerekse “üslûbu’l-Kur’ân”, “takdim-tehir” gibi başlıklar altında yer bulduğu tespit edilmektedir. İlgili başlıklarda yer verilen ayetlerin, Zemahşeri ve Razi tefsirlerinde münâsebât merkezli bir bağlamda ele alınması, münâsebâtü’l-Kur’ân’ın tarihine ilişkin kayda değer bir bulgu olarak ortaya çıkmaktadır. Bu araştırmanın sonuçları, müteakip ulûmu’l-Kur’ân literatüründe de münâsebât ilminin izinin sürülmesinin bir gereklilik olduğu fikrini desteklemektedir.
Procesos identitarios: análisis de cuestionarios a Profesores de Teatro
Authors: Goñi Martha Judit
Published: April 2023

El presente trabajo forma parte de la Tesis de Doctorado de la autora, dirigida por la Magister Cristina Erausquin: Los profesores principiantes. Vivencias y aprendizajes en la construcción de identidades. La misma se propone identificar, describir y analizar vivencias y aprendizajes que caracterizan la construcción de identidades de los profesores principiantes de teatro egresados de la Facultad de Arte de la Universidad Nacional del Centro de la Provincia de Buenos Aires. La muestra está compuesta por egresados de los años 2015 a 2019. (Se seleccionaron los últimos años antes de comenzar con los trabajos de la tesis en 2020). 
En esta etapa se sistematizaron los cuestionarios que se administraron en el año 2021. Los cuestionarios tuvieron por objetivo iniciar el contacto con los egresados de la carrera de Profesor de Juegos Dramáticos (primer título intermedio de la carrera de Profesor de Teatro, ambos habilitantes para el trabajo de profesor en el Sistema Educativo).
El tema es abordado desde una perspectiva socio-histórico-cultural, considerando el inicio de la docencia como un objeto complejo. Se trata de una etapa muy particular, ya que son los primeros momentos en los que se afrontan situaciones genuinas de enseñanza, sin la ayuda de los profesores que generaban orientaciones. Ya no se es estudiante y se ha adquirido una «libertad» o «independencia», en tanto cada uno elegirá cómo ejercer la profesión desde una «autonomía profesional».
En el texto se analizarán situaciones que se consideran intervienen en la constitución de identidades. Situaciones vinculadas con las culturas disciplinares, con las comunidades escolares, con la formación docente y con las trayectorias de vida. Estas situaciones implican un interjuego entre lo inter y lo intra psicológico y entre lo situacional e histórico.
Las experiencias de los docentes son interpeladas desde la perspectiva socio - cultural, articulando un análisis interdisciplinario, entre lo psico-socio-educativo, la acción y la concepción pedagógica situada en escenarios escolares.

Plan Dalet, the Palestine Nakba and Theatre: Decoding the Diacritics of the 1948 Nakba in Hannah Khalil’s Plan D
Authors: Bagoury Mahmoud El
Published: April 2023

This article scrutinises the disastrous impacts of Israeli occupation on Palestinians in the Palestinian-Irish playwright Hannah Khalil’s Plan D (2010) by decoding the diacritics of the Palestine Nakba of 1948. Plan Dalet was a Zionist master plan for the military occupation of Palestine and the plan became central to the Zionist expulsion of the Palestinians and Palestine Nakba in 1948. Khalil’s play ( Plan D) portrays a rustic family undergoing a crisis against a background of enforced mass deportation and ethnic cleansing of Palestine in 1948. The playwright gives a voice to the victimised Palestinians as the play represents an indictment of ecological imperialism which weighs upon Palestinians who are crammed into unlivable ghettos. Khalil’s attachment to her native environment shapes the portrayal of her characters and their environment which is exposed to demographical changes and distortion by reason of the Nakba. Psychologically, the play delves deeply into the tragedy of Palestinians who are forcibly deported from their farm houses to live in other ecological units such as the woods and outskirt camps and how they adapt to the new-found ecology as a survival mechanism aloof from the unscrupulous aggression of occupation. Put differently, it dismantles the diacritics of the plight of Palestinians and deconstructs projections of otherness in order to find an ecological outlet for them to rethink their life-threatening crisis.
Reclaiming History from the Settler Coloniser: A Meditation on Nur Masalha's Palestine across Millennia: A History of Literacy, Learning and Educational Revolutions
Authors: Docker John
Published: April 2023

In this wonderful book, Nur Masalha challenges and transforms world history, as did his earlier Palestine: A Four Thousand Year History (2018). In this meditation I recount some of Nur Masalha's argument — not all, given the extraordinary richness of the material he has uncovered, described, and analysed — but also offer my own reflections prompted by his book. As Masalha relates in his introduction, the work is a passionate response to Zionism's historical claim that Palestinians possess no history of literacy, education, and literary culture. He shows the falsity of such a claim through multiple examples. Masalha explores, for example, the multifaceted history of education in Byzantine Palestine (Third to Early Seventh Century), based on a philosophy of ‘civil society’. Palestine as a cosmopolitan and transnational world inhered in what Masalha refers to as Cities of Learning. There were famous intellectuals, such as in antiquity Josephus (AD 37-c.100) and Origen (AD 185–253). In modernity he highlights Khalil Sakakini (1878–1953), whose remarkable educational reforms, emphasizing a ‘philosophy of joy’, emerged at a similar time to A.S. Neill's Summerhill School in the UK. Women's education is featured, from the time of the Palestinian Madrasas under the Ayyubids and Mamluks (1187–1517) onwards, a powerful tradition which continues into the modern era. When press censorship was relaxed following the Ottoman Young Turk Revolution of 1908, there was a huge growth of newspapers, photography, and photojournalism, a remarkable figure here being the Palestinian photographer Karima ‘Abboud (1893–1940). Masalha draws attention to the importance of translation in Palestinian history, especially in the important figure of Khalil Ibrahim Beidas, a relative of Edward Said, who was interested in the works of Pushkin, Gogol, Dostoevsky, Tolstoy and Gorky. There is a fascinating chapter on the interactions of Palestinian scholars and the Crusaders, with free passages of ideas, goods and technologies; arabesque became a mainstream European decorative art. The result of these multiple explorations is a major transformation in how we think about the world.

On the basis of archival materials and published sources introduced into scientific circulation for the first time, the article examines the problems of adapting technologies obtained by the USSR as a result of World War II to Soviet production conditions. A number of them have been developed as a result of cooperation between industry and research institutes, which has allowed them to find new areas of application. Thus, the Ansonite cardboard, as it was replaced in construction with other materials, began to be used for insulating plastered surfaces and water supply pipes. The publication focuses on the impact on the production process of the transition of production from TU (technical specifications) to GOSTs (state standards). In conclusion, it was concluded that the successful development of cardboard production was associated with long-term cooperation between production and research institutes, which ensured the production of new types of «Ensonite» cardboard.

The soft computing FFNN method for adjusting heteroscedasticity on the time series model of currency exchange rate
Authors: Devianto Dodi , Yollanda Mutia , Maiyastri Maiyastri , Yanuar Ferra
Published: April 2023

Introduction

Time series models on financial data often have problems with the stationary assumption of variance on the residuals. It is well known as the heteroscedasticity effect. The heteroscedasticity is represented by a nonconstant value that varies over time.

Methods

The heteroscedasticity effect contained in the basic classical time series model of Autoregressive Integrated Moving Average (ARIMA) can adjust its residuals as the variance model by using Generalized Autoregressive Conditional Heteroscedasticity (GARCH). In improving the model accuracy and overcoming the heteroscedasticity problems, it is proposed a combination model of ARIMA and Feed-Forward Neural Network (FFNN), namely ARIMA-FFNN. The model is built by applying the soft computing method of FFNN to replace the variance model. This soft computing approach is one of the numerical methods that can not be only applied in the theoretical subject but also in the data processing.

Results

In this research, the accuracy of the time series model using the case study of the exchange rate United States dollar-Indonesia rupiah with a monthly period from January 2001 to May 2021 shows that the best accuracy of the possible models is the model of ARIMA-FFNN, which applies soft computing to obtain the optimal fitted parameters precisely.

Discussion

This result indicates that the ARIMA-FFNN model is better used to approach this exchange rate than the rest model of ARIMA-GARCH and ARIMA-GARCH-FFNN.
Zwitterionic coating assisted by dopamine with metal-phenolic networks loaded on titanium with improved biocompatibility and antibacterial property for artificial heart

Published: April 2023

Introduction: Titanium (Ti) and Ti-based alloy materials are commonly used to develop artificial hearts. To prevent bacterial infections and thrombus in patients with implanted artificial hearts, long-term prophylactic antibiotics and anti-thrombotic drugs are required, and this may lead to health complications. Therefore, the development of optimized antibacterial and antifouling surfaces for Ti-based substrate is especially critical when designing artificial heart implants.

Methods: In this study, polydopamine and poly-(sulfobetaine methacrylate) polymers were co-deposited to form a coating on the surface of Ti substrate, a process initiated by Cu2+ metal ions. The mechanism for the fabrication of the coating was investigated by coating thickness measurements as well as Ultraviolet–visible and X-ray Photoelectron (XPS) spectroscopy. Characterization of the coating was observed by optical imaging, scanning electron microscope (SEM), XPS, atomic force microscope (AFM), water contact angle and film thickness. In addition, antibacterial property of the coating was tested using Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) as model strains, while the material biocompatibility was assessed by the antiplatelet adhesion test using platelet-rich plasma and in vitro cytotoxicity tests using human umbilical vein endothelial cells and red blood cells.

Results and discussion: Optical imaging, SEM, XPS, AFM, water contact angle, and film thickness tests demonstrated that the coating was successfully deposited on the Ti substrate surface. The biocompatibility and antibacterial assays showed that the developed surface holds great potential for improving the antibacterial and antiplatelet adhesion properties of Ti-based heart implants.

Published: April 2023

CD34 is a cell surface antigen expressed in numerous stem/progenitor cells including hematopoietic stem cells (HSCs) and endothelial progenitor cells (EPCs), which are known to be rich sources of EPCs. Therefore, regenerative therapy using CD34+ cells has attracted interest for application in patients with various vascular, ischemic, and inflammatory diseases. CD34+ cells have recently been reported to improve therapeutic angiogenesis in a variety of diseases. Mechanistically, CD34+ cells are involved in both direct incorporation into the expanding vasculature and paracrine activity through angiogenesis, anti-inflammatory, immunomodulatory, and anti-apoptosis/fibrosis roles, which support the developing microvasculature. Preclinical, pilot, and clinical trials have well documented a track record of safety, practicality, and validity of CD34+ cell therapy in various diseases. However, the clinical application of CD34+ cell therapy has triggered scientific debates and controversies in last decade. This review covers all preexisting scientific literature and prepares an overview of the comprehensive biology of CD34+ cells as well as the preclinical/clinical details of CD34+ cell therapy for regenerative medicine.
Pro- and anti-tumour activities of CD146/MCAM in breast cancer result from its heterogeneous expression and association with epithelial to mesenchymal transition

Published: April 2023

CD146, also known as melanoma cell adhesion molecule (MCAM), is expressed in numerous cancers and has been implicated in the regulation of metastasis. We show that CD146 negatively regulates transendothelial migration (TEM) in breast cancer. This inhibitory activity is reflected by a reduction in MCAM gene expression and increased promoter methylation in tumour tissue compared to normal breast tissue. However, increased CD146/MCAM expression is associated with poor prognosis in breast cancer, a characteristic that is difficult to reconcile with inhibition of TEM by CD146 and its epigenetic silencing. Single cell transcriptome data revealed MCAM expression in multiple cell types, including the malignant cells, tumour vasculature and normal epithelium. MCAM expressing malignant cells were in the minority and expression was associated with epithelial to mesenchymal transition (EMT). Furthermore, gene expression signatures defining invasiveness and a stem cell-like phenotype were most strongly associated with mesenchymal-like tumour cells with low levels of MCAM mRNA, likely to represent a hybrid epithelial/mesenchymal (E/M) state. Our results show that high levels of MCAM gene expression are associated with poor prognosis in breast cancer because they reflect tumour vascularisation and high levels of EMT. We suggest that high levels of mesenchymal-like malignant cells reflect large populations of hybrid E/M cells and that low CD146 expression on these hybrid cells is permissive for TEM, aiding metastasis.
Climate-change scenarios require volatility effects to imply substantial credit losses: shocks drive credit risk not changes in economic trends
Authors: Aguais Scott D. , Forest Laurence R.
Published: April 2023

Introduction

Long-run Macro-Prudential stability objectives for the banking system have recently motivated a detailed focus on potential future credit risks stemming from climate change. Led by regulators and the NGFS, early approaches apply smooth, top-down scenarios that utilize carbon emissions data combined with physical risk metrics. This general climate stress test approach assesses future credit losses for individual firms and the banking system. While the NGFS approach is in its infancy, a number of discussion points have been raised related to how the approach assesses future credit risks. In contrast to the NGFS approach that focuses on changes to long-run economic growth trends, higher credit risks generally arise from unexpected economic shocks to cashflows and asset values. Systematic shocks that impact many firms like those observed during the last three economic recessions clearly produce higher volatility and systematic deviations from average economic trends.

Methods

In this paper we briefly review aspects of current climate stress test approaches to set the context for our primary focus on assessing future climate induced credit risk and credit risk volatility using a multi credit-factor portfolio framework applied to a benchmark US C&I credit portfolio. First we compare various NGFS climate scenarios using NGFS GDP measures to a CCAR severely adverse stress scenario. We then undertake two additional assessments of future climate driven credit risk by applying an assumed relationship between NGFS global mean temperatures (GMTs) and credit-factor volatilities. All three prospective climate credit risk assessments utilize an empirically-based, credit-factor model estimated from market-based measures of credit risk to highlight the potential role for climate induced increases in volatility. The potential future drivers of volatility could stem from narrower physical risks or broader macro-economic, social or other systematic shocks driven by climate change. All three predicted credit loss assessments suggest that volatility not changes to economic trends ultimately drives higher potential credit risks relating to climate change.

Contributions

The key contributions of this paper are the application of empirically based credit factor models combined with higher climate-driven volatility assumptions that support statistical assessment of how climate change could impact credit risk losses.
