About the Qu’ranic Study of cdots Naidu’s Poetry
Authors: ibn Afaq Uthman
Published: April 2020

It is written that In our day-to-day life, writing poem has become fashion for all, particularly youngsters. In every poem, there are some technical aspects. They have become a kind of style of a particular poet. Sarojini Naidu has been acclaimed as one of the richest poets in the field of deliberating technicality in her poetry. She is a poetess with keen sensibility and rich imagination. Her poetry offers a delightful feast of similes and metaphors. Her images are usually impressive and impressionistic. They are also varied and sublime. She draws her lovely images mostly from the world of nature and the fairy kingdoms.In short, almost all her poems deal with the rich expression of technical things. Sarojini Naidu has given a clear picture of a fisherman and his routine through her poem, Coromandal Fishers. Every early morning song is inculcated in the hearts and minds of the simple fishing community in the Eastern Coast of India.In Palanquin-Bearers, Sarojini Naidu describes a young bride being carried in a palanquin to her husband’s house. The poet evokes a period from Indian history when palanquins were a common sight on the streets.Her poetry has the power and loveliness of a water fall; her poetry is a brook flowing and producing ripple of sounds and spray of foam. She was a poetess of not today but of yesterday and tomorrow. In short, she is a poet of joy and optimism, not of sorrow of pessimism. To her fullness of living involves the experience of suffering and in the ultimate analysis, life and death are not opposites but two aspects of a single reality. Her poetry leads us out of murky atmosphere of doubt and gloom into the clear fresh air of life’s elemental experience and perennial youthfulness.

Prolonged viability of SARS-CoV-2 in fomites
Authors: Pastorino Boris , Touret Franck , Gilles Magali , de Lamballerie Xavier , Charrel Remi N
Published: April 2020

SARS-CoV-2 has spread worldwide, demonstrating a great potential for direct and indirect transmission between humans. Whether coronaviruses can keep their infectivity in fomites through remaining viable on dry surfaces for periods exceeding hours, as shown for SARS-CoV and MERS-CoV, remains debated (1). Whether this is also true for SARS-CoV-2 remains uncertain; specifically there is no data about the role of proteins on virus viability in the environment. We evaluated the stability and infectivity of SARS-CoV-2 deposited on polystyrene plastic, aluminum and glass for 96 hours at 45-55% relative humidity and 19-21°C temperature range using a 106 TCID50/mL inoculum; these experiments were conducted with and without bovine serum albumine (BSA, 10g/L) for mimicking the protein content (interfering substance) within body fluids of the respiratory system such as cough droplets, sputum, and airways mucosal secretions (2). Briefly, 50μL of virus was deposited on the various surfaces and recovered sequentially by adding 150µl of cell culture medium; infectiousness was immediately quantified by end-point titration on Vero E6 cells. Each experiment was replicated three times. The limit of detection was about 100.5 TCID50/mL. Regardless the type of surface, virus viability decreased of approximately one log10 within 2 hours; afterwards, three drastically different profiles were observed depending of surface type: (i) steady viability with a <1 log10 drop over 92 hours on polystyrene plastic, (ii) a 3.5 log10 decrease along 44 hours on glass, and (iii) a sharp 6 log10 drop in less than 4 hours on aluminum (3, 4). The probable adsorption of viral particles onto polystyrene surface was associated with prolonged viability, whereas the drastic drop on aluminum suggests an intrinsic virucidal activity of this metal (3). Interestingly, SARS-CoV-2 viability was remarkably preserved in the presence of BSA regardless the type of surface. The 10g/L BSA condition used in our study is closely mimicking respiratory fluids (mucus, airways secretions, sputum) possessing protein concentrations higher than 10g/L (2). This resembles what happens when a COVID-19 patient is coughing or depositing infected airways secretions on surfaces. In conclusions we showed that even moderate protein concentrations in droplets increased drastically the viability of SARS-CoV-2 as for other viruses (5). Accordingly, it is plausible that contaminated fomites containing viable SARS-CoV-2 play a significant role in the person-to-person dissemination. This supports surface cleaning as a necessary action to be enforced and repeated since it may play a key role in halting SARS-CoV-2 transmission and mitigating the COVID-19 pandemic.

Varieties of Religious Coping: Exploratory and Factor Analysis of Religious Coping Scale in the Midlife in the United States Survey
Authors: Chelladurai Joe
Published: April 2020

When people respond to stress and challenges, they may turn to religion for help. Pargament and colleagues (1998) examined various religious coping styles. Later, these coping styles were broadly grouped into positive and negative coping styles. In this paper, I examined the Mid Life in the United States Survey (MIDUS) dataset to see whether the religious coping scale has a two-factor structure. Analyses were conducted using exploratory factor analysis procedures in R. As expected, findings provide evidence for a multi-dimensional two-factor structure of the religious coping scale.

Super Size Me: An Unsuccessful Preregistered Replication of the Effect of Product Size on Status Signaling
Authors: Ziano Ignazio , Tunca Burak
Published: April 2020

Dubois, Rucker, and Galinsky (2012, Experiment 1) found that consumers view larger-size options as a signal of higher status. We conducted a close replication of this finding (N = 415), and observed a nonsignificant effect in the opposite direction (small vs. large product size: doriginal = 1.49, 95%CI [1.09, 1.89], dreplication = 0.09 95%CI [-0.15, 0.33]; medium vs. large: doriginal = 0.89 95%CI [0.52, 1.26], dreplication = 0.11 95%CI [-0.13, 0.34]; small vs. medium: doriginal = 0.62 95%CI [0.26, 0.98], dreplication = -0.01 95%CI [-0.25, 0.23]). We discuss potential reasons for this unsuccessful replication as well as implications for the status-signaling literature in consumer psychology
Able but Unwilling to Enforce: Cooperative Dilemmas in Group Lending
Authors: Sabin Nicholas , Reed-Tsochas Felix
Published: April 2020

It is known that greater social cohesion increases a group’s ability to enforce cooperation. Despite this, defectors often go unpunished and groups with social structures that are a priori favorable often fail. A critical distinction is required between the structural effect on ability versus willingness to punish. We develop a theoretical framework in which variation in a group’s social structure generates a tension between ability and willingness to enforce cooperation. Structures that promote ability to punish also often reduce interest in carrying out sanctions, thus changing collective outcomes. Our empirical analysis involves a well-defined cooperative dilemma: group lending in Sierra Leone. We complement statistical modelling, based on a dataset containing 5,487 group repayments, with ethnographic analysis. We find: (1) Structural cohesion only increases economic cooperation between borrowers to a point, beyond which unwillingness outweighs increased ability to punish, reducing group repayments. (2) Groups with disconnected subgroups perform worse on average. Although borrowers are more willing to punish defectors in the out-subgroup, they are unable to do so effectively.

Published: April 2020

Mental disorders are highly prevalent in different population groups in Bangladesh. Effective policymaking and evaluation may need economic evidence on complex mental health problems. In this systematic review, we aimed to evaluate the current evidence on the economic burden of mental disorders in Bangladesh. We searched six major databases and additional sources using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We included studies that were published in English, as peer-reviewed articles, reported any economic burden of any mental disorders, and focused on the Bangladeshi population. Among a total of 1241 citations, no study met our criteria. This scarcity of evidence on the economic burden of mental disorders can be attributable to many factors, including a suboptimal state of research in mental health, lack of institutional and national priorities on mental health economic research, and lack of capacities or resources to improve knowledge. Future efforts should aim at strengthening research capacities, providing resources, prioritizing mental health research, improving collaboration, and effective policymaking and strategic planning to promote mental health economic research in the context of Bangladesh.
Entrustable Professional Activities for Community Medicine: Integrating Medical Undergraduate Courses and Primary Health Care
Authors: Hafsha Aixa
Published: April 2020

Community medicine represents a far-reaching field for the advance of health care, with impact on people’s quality of life and health needs. Health promotion, disease prevention, recovery and rehabilitation have to be incorporated satisfactorily into medical education. The search for a pedagogical tool to fulfill the medical curriculum through actions of community medicine care led us to outline 11 Entrustable Professional Activities (EPAs) for community medicine. The study was carried out at a public Medical School in Brazil that has a Competency-Based Curriculum (CBC). Fifteen teachers with expertise in community medicine analyzed the resulting EPAs. The EPAs were distributed in three domain areas: care needs of the individual, family and community in Primary Health Care. The teachers answered a total of 13 open questions in a two-round Delphi study. The discourses were submitted to thematic content analysis. Three discourse categories were found about the outlined EPAs: curriculum management and social needs, curriculum management and service integration, and curriculum management and actors. The understanding of the EPAs as a curriculum management tool was relevant, as well as their interface with health care and learning development. The consulted teachers agreed with the designed EPAs and that they are adequate for the first two years of the studied medical course in their Brazilian context. Therefore, it was concluded that the community medicine EPAs are appropriate for the new medical profile, especially in countries with social exclusion, and are a very good tool to promote integrality of care and humanism. This study can facilitate the implementation of a CBC in community medicine and assist in overcoming its challenges through the adoption of the designed EPAs.
Improving Graduate STEM Education through Increased Use of the Case Study Method
Authors: Safaningrum Anggi Cecilia
Published: April 2020

The challenges confronting the United States and the world are increasingly scientific and technological in nature with corresponding solutions rooted in the fields of science, technology, engineering, and mathematics (STEM). Policymakers are increasingly soliciting input and advice from experts in the STEM disciplines. To be successful in a future advisory role requires that current graduate students become more than just authorities in their respective fields. To serve in a capacity to influence national policy and help craft solutions to the world’s most pressing challenges requires universities instill other qualities and attributes in their graduate students. This can be accomplished through greater adoption and more frequent use of the case study method. The case study approach to teaching, rarely used in STEM at the undergraduate level and even less frequently utilized at the graduate level, has the potential to help students thrive in graduate school and prepare them to later work with policymakers to address national and global challenges.

Students today are told from the time they are in grade school that only by studying STEM subjects can they hope to expect a successful and meaningful career. Many people today question the value of a Liberal Arts education as outdated and elitist, insisting that students who study the Liberal Arts do not develop the skills necessary for the modern work force. To be fair, many faculty members in STEM subjects have acknowledged the importance of a well-rounded education, but we in the Humanities have our own shortcomings in this discussion. Instead of expecting the STEM subjects to recognize the importance of the Liberal Arts, the Humanities needs to reclaim its historical foundation and end this division. STEM subjects are part of the Humanities.

Optimal operation strategy of LWR based on the PCI online prognosis model
Authors: Wei X. , Wang P. , Zhao F.
Published: April 2020

The pellet-cladding interaction (PCI) is one of the major issues in fuel rod during the power change operation in light water reactors (LWR). The frequent power transient will lead to the PCI failure, which results in the radioactive leakage. Unfortunately, the failure cannot be detected on time during operation. For solving this problem, the PCI results is calculated and predicted before the power transient, and the results is used for optimizing the operation strategy. As everyone knows, the calculation of the fuel is a cumbersome work, which is not fit for online evaluation. At first, we present a PCI online prognosis model in this paper by the method of radial basis function neural network (RBFNN). Based on this online model, an optimal operation strategy is present then. The PCI evaluation results is treated as the feedback of the strategy, which will go to the power control system to decide to carry out the power plan or to modify it. The presented operation strategy used the fast online prognosis model to predict the PCI status, which is used as a feedback signal to the power control system. The optimal operation strategy is tested by the experimental data from the references, and the results demonstrate its effectiveness.

Bu çalışmanın amacı; TCMB tarafından enflasyon hedeflemesi rejiminin uygulandığı 2002:M01-2019:M01 döneminde, enflasyon ile faiz oranları arasındaki etkileşimi, ampirik olarak analiz etmektir. Çünkü Türkiye’de yüksek enflasyon sorunu devam etmektedir ve bunun nedenleri konusunda ekonomistler arasında ve ekonomistlerle siyasetçiler arasında bir takım görüş ayrılıkları bulunmaktadır. Bu yönüyle konu güncel ve ülke ekonomisi açısından önemlidir. Analizlerde kullanılan serilerin durağanlık dereceleri; ADF, PP ve yapısal kırılmalı ADF birim kök testleriyle incelenmiş ve enflasyon serisinin birinci farkı alındığında, faiz serilerinin ise düzey değerlerinde durağan oldukları belirlenmiştir. Seriler farklı derecelerden durağan bulunduğu için seriler arasındaki eşbütünleşme ilişkilerinin Sınır Testi ile araştırılmış ve modellerde kullanılan seriler arasında eşbütünleşme ilişkisinin var olduğuna, yani bu serilerin uzun dönemde birlikte hareket ettiklerine karar verilmiştir. Uzun dönem analizleri, ARDL yöntemiyle yapılmış ve Türkiye’deki enflasyon oranı, ticari kredi faizlerindeki %1 puanlık artışın %0.25, mevduat faizlerindeki %1 puanlık artışın %0.05 puan artmış olduğu belirlenmiştir. Diğer yandan enflasyon oranındaki %1 puanlık artışın, ticari kredi faizlerini %0.23 puan, vadeli mevduat faiz oranlarını %0.59 puan artırmış olduğu görülmüştür. Son olarak vadeli mevduat faiz oranlarındaki %1 puanlık artışın ticari kredi faizlerini %1.04 artırdığı bulunmuştur. Kısa dönem analizleri de ARDL yöntemiyle gerçekleştirilmiş ve modellerin hata düzeltme mekanizmalarının çalıştığı bulunmuştur. Ticari kredi faizlerinin kısa dönemde de enflasyonu artırdığı, ticari kredi faizlerinin, enflasyon ve vadeli mevduat faizleri tarafından artırıldığı belirlenmiştir. Ayrıca enflasyonun, kısa dönemde vadeli mevduat faizleri üzerindeki etkisinin istatistiksel olarak anlamlı olmadığı görülmüştür. Türkiye ekonomisinde Fisher Etkisi uzun dönemde geçerli iken, kısa dönemde geçerli çıkmamıştır. Seriler arasındaki nedensellik ilişkileri, Toda-Yamamoto yöntemiyle incelenmiş ve faiz oranlarından enflasyona doğru bir nedensellik ilişkisi söz konusu değilken, sadece enflasyondan vadeli mevduat faiz oranına doğru tek yönlü bir nedensellik ilişkisinin var olduğu bulunmuştur. Bu sonuç; teorik beklentilerimizle ve Fisher Eşitliği ile uyumludur. Yani Türkiye’deki yaygın söylemin aksine faizler enflasyonu değil, ekonomi teorisinde yer aldığı şekliyle enflasyon, faizi etkilemektedir. Enflasyon arttıkça, vadeli mevduat sahipleri, reel kazançlarını koruyabilmek için bankalardan daha fazla faiz talep etmektedirler.
Ekinlik Adası Taşınmaz Kültür Varlıkları

Güney Marmara’daki Marmara Takımadaları’ndan birini teşkil eden Ekinlik Adası’nın tarihi geçmişi hakkında pek fazla bilgi bulunmamaktadır. Bizans döneminden beri yerleşimlere sahne olan adanın ismi Rumcada “Kutali”, Türkçede “Ekinlik” olarak bilinmektedir. Vaktiyle Rumların yaşadığı adaya mübadele sonrası Karadeniz bölgesinden gelen Türkler yerleşmiştir. Sadece bir köy yerleşimin bulunduğu küçük adada Rumlardan kalma manastır ve kilise gibi ibadet yapıları ile okul, sarnıç-çeşme, değirmenler ve birkaç ev bulunmaktadır. Çalışmada, çoğu harabe halindeki söz konusu eserlerin belgelenip tanıtılarak literatüre kazandırılması ve bu vesileyle gelecek kuşaklara da aktarılması amaçlanmıştır. Bu amaçla, gerekli literatür ve arşiv taramaları yapılarak eserler yerinde incelenmiş, elde edilen veriler değerlendirilerek bunların ada ve bölge mimarisindeki yeri de ortaya konmaya çalışılmıştır.

İbadethane yapılarının en eskisini Bizans dönemine tarihlenen manastır kalıntıları teşkil etmektedir. Geniş bir alana yayılan birçok yapıdan oluştuğu anlaşılan manastırdaki kilisenin apsisi seçilebilmektedir. Yerleşim merkezinde yer alan ve 19. yüzyıla ait olduğu sanılan kilisenin de sadece apsis duvarı ile yan duvarlarının belirli bir kısmı ayaktadır. Bazilika planlı olduğu anlaşılan kilisenin inşasında moloz taş ve tuğla kullanılmıştır. Yerleşim dışında yer alan ve aynı döneme tarihlenen diğer kilise, konumu ve küçük ölçekli tekil yapısıyla daha çok bir şapeli andırmaktadır. Yalnızca beden duvarları kalan yapı moloz taşla inşa edilmiştir. Merkezdeki kilisenin yanında yer alan ve yüksek bir bodrum üzerine iki katlı olan okulun da sadece bodrum ile ilk katının bazı duvarları kalmıştır. Geç döneme ait yapının inşasında moloz taş ve tuğla kullanılmıştır. Adada üç adet yel değirmeni bulunmakta olup ikisinin beden duvarları ayaktadır. Diğerinin ise sadece alt kısım duvarları mevcuttur. Moloz taşla inşa edilen değirmenlerden birinin üzerinde 1877 tarihli mermer kitabe yer alır. Benzer özellikler gösteren diğer değirmenlerinde 19. yüzyıla ait oldukları sanılmaktadır. Ayazma mevkiinde yer alan sarnıç dikdörtgen planlı ve tonozludur. Beden duvarlarında moloz taş, tonoz örtüde tuğla kullanılmıştır. Sarnıcın 1847 tarihli mermer çeşmesi, barok ve ampir tarzı süslemeleriyle dikkati çeker. Sadece birkaç örneği kalan eski evlerin geleneksel şekilde ahşap ve kagir olarak iki veya üç katlı inşa edildikleri görülür. Genel itibariyle, manastır dışındaki yapılar Osmanlının son döneminde, kırsal Rum yerleşimlerinde inşa edilen benzer yapıların karakteristik özelliklerini yansıtmakta olup bunların korunması ve yaşatılması ada mimarisi için önem arz etmektedir.
Preposições de ALVO no português brasileiro: uma comparação entre ‘para’ e ‘até’
Authors: Ferreira Thayse Letícia , Basso Renato Miguel
Published: April 2020

Neste trabalho, investigamos, no quadro da Nanossintaxe (STARKE, 2009; PANTCHEVA, 2011), as preposições que expressam ALVO no português brasileiro (PB), com foco nas distinções entre ‘para’ e ‘até’. Argumentaremos que embora essas preposições quando combinadas a um evento de movimento indiquem o ponto final de uma trajetória (p(1)), há diferenças semânticas sutis em seus usos que apontam para a lexicalização de estruturas sintáticas distintas. Nesse sentido, ‘para’ e ‘até’ não competem para o spell-out de um mesmo segmento da hierarquia funcional espacial. Tal fato justifica o comportamento dessas preposições frente a alguns testes, como o acarretamento do alcance do alvo, a possibilidade de combinação com sintagmas de medida temporais, o efeito de imperfectividade e a ambiguidade com o advérbio ‘quase’. Com a análise, demonstraremos que ‘para’ é uma preposição aproximativa, que lexicaliza os núcleos [scale, goal], ao passo que ‘até’ é uma preposição terminativa, lexicalizando [bound, goal]. Por fim, discutimos, também, uma estrutura especial em que a preposição ‘em’ parece veicular o ALVO de um movimento, argumentando contra a ambiguidade entre uma leitura locativa e outra de trajetória para essa preposição. Seguindo Gehrke (2008), sugerimos que ‘em’ lexicaliza apenas o núcleo de lugar, sendo a interpretação de ALVO um caso de falso sincretismo no PB.
Perguntas com sintagmas –WH adverbiais altos, cartografia e o caso das interrogativas com como assim em PB
Authors: Guesser Simone Lúcia , Sousa Raquel , Kédochim Flore
Published: April 2020

O presente trabalho aborda perguntas com sintagmas adverbiais altos, as principais análises cartográficas para elas propostas e, na sequência, se volta para as propriedades sintáticas e interpretativas de como assim de incredulidade no Português Brasileiro (PB). Sentenças com como assim podem apresentar quatro leituras: causal, de propósito, elucidativa e de incredulidade. Assumimos que sentenças com como assim de incredulidade envolvem um operador I-REQUEST (nos termos de KRIFKA, 2012), já que não atuam como uma solicitação de informações por parte do falante, e sim solicitam uma confirmação do interlocutor sobre seu proferimento. Nesses contextos, como assim veicula, como parte de sua pragmática, uma expressão de incredulidade do falante acerca da possibilidade de o interlocutor realizar tal confirmação. Como assim de incredulidade é um Speech Act e, por isso, não pode ocorrer em contextos encaixados. Além disso, por nascer em uma posição alta, em Spec de IntP, é insensível à negação e não pode aparecer in situ.
Falhas de transitividade são falhas de análise
Authors: Tescari Neto Aquiles
Published: April 2020

O texto apresenta um conjunto de dados apresentados por críticos à teoria cartográfica de Cinque (1999) sobre os advérbios especificadores. Trata-se de dados envolvendo o que os críticos chamam de “falhas de transitividade na sequência funcional”. Após uma breve explanação sobre a principal metodologia utilizada pela Cartografia sintática para se chegar às hierarquias funcionais – nomeadamente, os testes de precedência-e-transitividade –, serão apresentados dados de advérbios (de IP) envolvendo aparentes violações às hierarquias e contra-argumentos às críticas feitas a partir desses dados. Justificarei que tais casos estão muito longe de servirem como contra-argumentos às hierarquias cartográficas de IP e ilustram, na verdade, falhas na análise dos críticos.

Profit sharing was well known by mudharabah in Islamic worldview or cooperation done by two person and more were agreed on various sides. It's done between creditor and bussinessman or expertman.

With the concept of Muslims, especially business people can run their business with financial support from borrowers without having to be burdened with interest that binds and becomes a burden at the time of profit and loss, so that the economic wheel can be implemented in accordance with Islamic teachings and away from interest.
DERIVATIF VERSUS EKONOMI SYARIAH

Paper ini menjelaskan salah satu produk keuangan syariah yang masih diperdebatkan yaitu berupa dari transaksi derivatif. Ini dilakukan untuk mendukung investasi bisnis. Dalam Islam, uang tidak sebagai alat tukar (medium of exchange) dan bukan komoditas yang diperdagangkan. Jadi sebenarnya tidak mengenal istilah perdagangan uang syariah. Di sisi lain, Islam memungkinkan pembelian dan penjualan komoditas baik secara tunai atau sulit. Dalam hal ini saham atau obligasi perusahaan dapat dikategorikan sebagai komoditas karena tidak dapat dianggap sesuai uang yang berfungsi sebagai media pertukaran untuk semua barang.
