Authors: Mamoor Shahan
Published: February 2020

Ovarian cancer is most common reason for a gynecological cancer death in the developed world (1). There are zero targeted chemotherapies available for the treatment of ovarian cancer. We studied the transcriptomes of tumors from ovarian cancer by comparing them to the transcriptome of normal ovarian tissue using two separate datasets (2, 3). We found that the cadherin-like and PC esterase domain containing 1, CPED1, was among the genes whose expression changed the most between ovarian tumors and the normal ovary. This is the first report of differential expression of CPED1 in ovarian cancer.

Do Sequential Lineups Impair Discriminability?
Authors: Kaesler Matthew Philip , Dunn John C , Ransom Keith , Semmler Carolyn
Published: February 2020

The debate regarding the best way to test and measure eyewitness memory has dominated the eyewitness literature for more than thirty years. We argue that to resolve this debate requires the development and application of appropriate measurement models. In this study we develop models of simultaneous and sequential lineup presentations and use these to compare the procedures in terms of discriminability and response bias. We tested a key prediction of the diagnostic feature detection hypothesis that discriminability should be greater for simultaneous than sequential lineups. We fit the models to the corpus of studies originally described by Palmer and Brewer (2012, Law and Human Behavior, 36(3), 247-255) and to data from a new experiment. The results of both investigations showed that discriminability did not differ between the two procedures, while responses were more conservative for sequential presentation compared to simultaneous presentation. We conclude that the two procedures do not differ in the efficiency with which they allow eyewitness memory to be expressed. We discuss the implications of this for the diagnostic feature detection hypothesis and other sequential lineup procedures used in current jurisdictions.
Cognitive dimensions of learning in children with problems in attention, learning and memory
Authors: Holmes Joni , Guy Jacalyn , Bryant Annie , Kievit Rogier , Team the CALM , Gathercole Susan Elizabeth
Published: February 2020

A data-driven, transdiagnostic approach was employed to identify the cognitive dimensions linked with learning in a large mixed group of children recognised to have problems in the areas of attention, learning and memory by a health or education practitioner (N=805). The children completed a battery of cognitive assessments tapping phonological processing, information processing speed, short-term and working memory, and executive functions, and attainments in reading, spelling, vocabulary and maths. Data reduction methods identified three cognitive dimensions of phonological processing, processing speed and executive function for the sample as a whole. This model was comparable for children with and without ADHD. The severity of learning difficulties in literacy was linked to phonological processing skills, and in maths to executive control. Associations between cognition and learning were broadly comparable across subgroups, but learning-related problems were more strongly linked to executive skills and processing speed in children with ADHD than without ADHD. The results establish that domain-specific cognitive pathways to learning distinguish a large heterogeneous population of struggling learners. They also indicate that robust cognitive skills may be vital in compensating for the adverse impact of ADHD behaviours on learning.
A Study of Irony in Political Discourse
Authors: Qaiwer Shatha Naiyf
Published: February 2020

This study examines the ideological and evaluative nature of irony in discourse. It aims to reveal the linguistic constructions involved in ironic utterances and to uncover ideologies underpinning such structures. It draws upon the echo and pretense theories to account for utterance representation along with Wodak’s (2007) framework of self and other presentation strategies. The study examines the incongruous construction of an attitude, and the objectives attempted to achieve by taking a cynical stance. The main research questions center on the role played by ironic utterances and how they contribute to preserving the image of the speaker and to the negative representation of the other. The study reveals the way politicians mark their verbal irony, i.e., to classify and categorize the co-textual markers including hyperboles, and repetitive follow-up commentaries. The findings in this study support Bertuccelli (2018) view that irony is not merely saying the opposite of what one means but instead communicating an attitude. It adds to the existing literature that irony involves not a reversal of evaluation, but a reversal of attitudes about social actors to draw a positive self-image. Furthermore, the study shows that echoing the opponent's utterance involves a representation of acts and speech acts along with free direct and indirect speech.

Authors: Dirjal Ali Hasan , Ghabanchi Zargham
Published: February 2020

The purpose of this study is to investigate the impact of applying social media, specifically, using Skype devices in teaching the speaking skill (Male/Female) as a supportive environment of English language teaching. Moreover, this study seeks to find whether the designed questionnaire enjoys the required validity and reliability. As a case study, the sample of the experiment consists of seventy sophomores major in English at Mustansiriya University in Iraq. The researcher randomly divided the participants into control and experimental cohorts. The two groups submitted to the pretest and posttest. The participants of the study reported their responses to a six-statement designed questionnaire on suitable ways of improving the speaking skill. Statistical data have been collected based on the Likert Scale questionnaire, while the statistical values, such as mean, t-value, standard deviation, and chi-square, have been employed. The normality, confirmatory, validity, and reliability of the questionnaire were measured by using SPSS and LISREL programs. The research findings indicate that there is a significant difference in the speaking achievement between male and female participants who subjected to social media after receiving instructions via Skype devices. Based on these results, the impact of social media on students' achievements in speaking skills urges the need for a rethinking of the traditional method of teaching English. Further, educators should pay more attention to the process of employing social media applications in the educational domain.
New room to maneuver? National tax policy under in-creasing financial transparency
Authors: Ahrens Leo , Bothner Fabio , Hakelberg Lukas , Rixen Thomas
Published: February 2020

Why have OECD governments raised taxes on dividends at the shareholder level since 2008? Previous research points to the importance of budget deficits and voter demand for compensa-tory fairness in the aftermath of the financial crisis. We complement this literature by showing that the effect of domestic drivers of tax increases on capital income crucially depends on the level of financial transparency in a country’s investment network. Low financial transparency increases the risk of capital flight in response to a tax hike, whereas high financial transparency reduces this risk. Hence, governments facing fiscal pressure become more likely to raise taxes on capital income when transparency is high. To substantiate our argument, we construct an original indicator of financial transparency in countries’ investment networks, which we utilize in a regression analysis of tax reforms by 204 cabinets in 35 OECD countries between 2001 and 2018.

Low-complexity compensation of sampling offset with cross-correlation and early-late gate for OFDM receivers
Authors: Zhang Lingfei , Ma Jun , Liu Rongxin , You Zhonglun , Xiang Tingting
Published: February 2020

This paper proposes a method for compensation of sampling offset for orthogonal frequency division multiplexing (OFDM) used in wireless local area networks (WLAN). Sampling offset is a typical transmission interference used in OFDM systems that introduce large error when synchronized data is demodulated. In this regard, an appropriate offset compensation method with a simple structure can be adopted to mitigate the impacts of sampling offset by using cross-correlation and early-late gate compensation methods for OFDM receivers instead of conventional methods that use algorithms with analog and mixed mode loops implementations. When bit error rate (BER) is at 10-3, simulation with the method without sampling offset compensation showed a signal noise rate (SNR) curve of about 25 dB, while the SNR curve of the method with offset compensation as proposed in this paper is about 26 dB. The comparisons show that the proposed system sacrifices performance by 1 dB to realize the benefit of compensating sampling offset. This sacrifice of 1 dB in performance is within the system’s tolerance range. Furthermore, the method overcomes the impact of sampling offset without additional hardware resource in WLAN applications.

Rigid-flexible coupled multi-body dynamics analysis of horizontal directional drilling rig system
Authors: Wang Jianwei , Wang Shixuan , Le Haoyu , Ge Maoxin
Published: February 2020

To reduce the failure probability of gas drainage drilling holes in coal mines, a new modeling method of gas drainage drilling machine is presented. Firstly, each drill pipe is regarded as a flexible body, and the Lagrange’s equation of second kind is used to model it. Secondly, the joint of drill bit, hole wall and drill pipe are regarded as rigid bodies, and the Newton-Euler method is used to model it. Thirdly, the rigid-flexible coupling multi-body dynamic model of drilling rig-drill pipe-hole wall system in medium and short horizontal section of soft coal seam is established by using relative node coordinate method, and the time complexity and operation complexity of modeling are reduced by using ADAMS macro program. Finally, the finite element method is used to discretize the model, and the virtual prototyping technology is used to solve the mathematical model. The simulation results show that the coupling of friction and vibration does not necessarily increase the probability of drilling failure, but sometimes reduces the amplitude of vibration. Compared with the length of each drill pipe, the influence of drilling depth on the system is greater, and the bit-bounce behaviours is more likely to occur in the deep hole. The operating frequency range of the drilling rig is 6.9E-3 to 2.1E+4Hz. When the length of the drill pipe is constant, the natural frequency of the system increases with the increase of the order, while the natural frequency of the deep hole section is almost unaffected by the order. In practical engineering, the vibration excitation of the actuator should be controlled to avoid the natural frequency. Meanwhile, the modal frequency should be avoided as far as possible to reduce the vibration and the failure probability of drilling holes. The model can simulate a series of dynamic responses of drilling rig system in drilling process, and provide theoretical support for subsequent multi-factor coupling modeling.
Phase shift control dual active bridge converter with integrated magnetics
Authors: Gao Shengwei , Wang Hao , Tarafdar Kishor
Published: February 2020

Traditional dual active bridge converters use transformer leakage inductance instead of energy storage inductors for magnetic integration, but this method cannot accurately control the leakage inductance. A phase shift control dual active bridge converter base on integrated magnetics is proposed, in which one transformer and one inductor are integrated in an EE core. The size of the inductance can be accurately controlled. The transformer and the inductor are decoupled and integrated so that the two operating states do not affect each other. The weight and volume of the magnetic elements are reduced accordingly. The finite element analysis and magnetic circuit simulation of the integrated magnetics are carried out. Finally, the integrated magnetics are designed and applied to the 600W prototype to realize bidirectional power transmission and a weight reduction is about 36.24% and a volume reduction is about 35.84%. The correctness of the design is verified by experimental results.

Recently, the scientific and journalistic heritage of A.Richynsky as an ideologist and organizer of the Ukrainian church-national movement in Volyn in the 20-30s of the XX century has attracted considerable attention of researchers. From this perspective, the most outstanding work of A.Richinsky's "Features of Ukrainian Religious Consciousness" is analyzed by scholars, though we admit that the theological and philosophical component in A.Richinsky's religious heritage remains almost unexplored. The article will trace the formation of A. Richinsky's teaching on the relationship between the religious and ethnic in the Bible, in particular about the nation as established eternal reality. The basis for writing the article is the works of Arsen Rychinsky published in recent years.

WANITA MAYORITAS DI NERAKA, IMPERFEK AKAL DAN AGAMA: Antara Polemik, Solusi Dan Motivasi
Authors: Is Fadhilah
Published: February 2020

Hadis tentang wanita adalah objek yang intens dikomentari oleh para orientalis dan feminis. Mereka mendeskripsikan bahwa Islam mendikotomikan dan menjustifikasi wanita sebagai second public. Hadis yang diriwayatkan Imam Al-Bukhārī bahwa wanita adalah yang paling banyak menghuni neraka, karena banyak melaknat dan banyak mengingkari pemberian suami, dan kurangnya akal dan lemahnya agama wanita. Lafaz hadis ini baik tekstual ataupun konstektual tidak ada mengandung unsur misoginis, patriakhi, dikotomi, dan merendahkan wanita. Malah sebaliknya, memotivasi wanita untuk semangat menuntut ilmu, beribadah, takarub, bersedekah dan menjaga lisan. Di balik kekurangan wanita, sejatinya itulah kelebihan yang Allah berikan kepada mereka, agar saling melengkapi di antara sepasang manusia, laki-laki dan wanita.
INTERPRETASI MAKNA HADIS MENCEGAH KEMUNGKARAN DI TENGAH BERTABURNYA KEJAHATAN

Artikel mengkaji tentang hadis riwayat Muslim, yang mengatakan bahwa mencegah kemungkaran hendaklah dengan tangan, jika tidak mampu dengan lisan, selanjutnya dengan hati. Hadis tersebut akan diinterpretasi dalam konteks berbagai kecenderungan yang terjadi pada sebagian masyarakat. Ada orang yang suka menyombongkan diri, penguasa yang berbuat zalim, ada pula orang yang menentang kebaikan dan mengajak kepada keburukan serta kejahatan. Artikel ini menegaskan bahwa bahwa nahi munkar memerlukan persiapan dan keberanian dari setiap Muslim. Sehingga sangat disayangkan, jika umat Islam saat ini tidak memiliki keberanian dan kesanggupan melaksanakan nahi munkar dengan tangan dan lisan mereka, karena hanya mampu mencegah dengan hati. Sikap seperti ini adalah bukti kelemahan iman.

This study discusses about the rule is not necessarily weak sanad weak matan hadith is a rule that applies only to the weak hadith. The rules of tradition of this kind can be used with the following conditions: first, the support strength of other traditions his matan matching, narrated of narrators (sanad path) to another, as well as the quality is equal or better than the first chain of transmission paths. Second, the narrators do not be evil, or a liar, nor a forger of hadith and is not known as one who fahusya galaṭuhu (many false) and inattentive, not al-muttahimīna bil każib (accused of lying), not heretical and not majḥūl ‘ain. Third, Hadith ḍa‘īf not too weak as mursal hadith, mu‘allal, and mubham. So the traditions are not too weak, they could still acceptable (maqbūl) if there is a path sanad from another hadith. Fourth, the hadith-hadith has a martyr and mutābi‘, meaning not only narrated the hadith with a chain of transmission lines, because it could conflict with the rules that have been understandable, as the hadith matrūk.

Indeed, Hadist in secundar book of hadith consist of 4 kinds they are: matan, sanad, rawi and symbol of transfer hadith. The experts of hadith paid attention against these symbols because the research of the symbols gave information about sanad condition between connected or not. After research about transfer hadith methods, from many imam’s books in ulumul hadith, the writer got that methods which used by rawi are limited eight methods. They are samā‘, arḍ, ijazah, munāwalah, mukātabah, i‘lām, waṣiyah and wijādah. The writer thought that the symbol ‘an not from eight methods mentioned. It caused the difference about its result between connected or not. Some of the experts hadith thought that it is not connected. Most of the experts hadith thought it is connected with two requirements the first, the rawi must be safe of tadlish. The second, meeting of mu‘an‘in and mu‘an‘an ‘anhu.
جبر الأحاديث المرسلة بتعدد طرق أحاديث كتاب فضائل القرآن في مصنف عبد الرزاق نموذجا

Tujuan dari studi ini adalah untuk menguatkan hadis mursal dengan syawāhid dan mutāba‘āt. Yang dimaksud dengan al-jabr dan al-tarqiyah di sini adalah mendatangkan jalur periwayatan lain untuk hadis mursal yang hukumnya lebih kuat. Para ulama hadis sepakat bahwa hadis dhaif, yang kelemahannya ringan, seperti sū’ ḥifz perawi, atau  terputusnya sanad, seperti hadis mursal yang hilang seorang perawi sesudah sahabat, atau hadis yang diriwayatkan oleh perawi yang tidak diketahui ‘adālahnya dapat di naikkan derajatnya menjadi hasan li ghairihi. Alasan memilih kitab Faḍāil Qurān adalah karena banyak sekali hadis-hadis yang berhubungan dengan topik tersebut adalah dhaif, terlebih lagi dari kumpulan hadis Muṣannif ‘Abd al-Razzāq yang tidak mensyaratkan keshahihan dalam hadis- hadis kompilasinya. Dalam tulisan ini, penulis akan mendatangkan jalur periwayatan lain dari hadis mursal yang mursal juga dari jalur lain. Hal ini karena, hadis mursal sendiri saling menguatkan jika diriwayatkan dari jalur selain jalur mursil. Penulis juga akan mendatangkan riwayat yang bersambung dari jalur mursil, guna mengetahui perawi yang jatuh sesudah sahabat, adakah ia sahabat saja, atau sahabat dan tabiin. Sebagaimana penulis juga akan mendatangkan jalur periwayatan lain yang bersambung atau periwayatan sahabat lain. Dengan bantuan syawāhid dan mutāba‘āt ini, penulis akan menentukan mana saja hadis yang dapat naik derajat kepada hasan li ghairihi dan yang tetap mursal, karena terlalu parah kedhaifannya atau ketidak tersediaan syawāhid yang kuat.

Kehidupan umat Islam dari waktu ke waktu selalu mengalami perubahan, termasuk dalam persoalan nilai yang di jadikan ukuran atau standar. Akibat dari perubahan ini, terutama era pengetahaun dan teknologi segala sesuatu selalu di nilai dengan akal. Oleh sebab itu, banyak produk hukum Islam termasuk dalam hal politik kenegaraan tidak bisa di terima begitu saja, karena tidak sesuai dengan akal, salah satu contoh kepemimpinan perempuan. Hadis yang di jadikan landasan bagi ketidak bolehan pemimpin perempuan di pandang sudah tidak relevan lagi dengan perubahan kondisi struktur sosial, ekonomi dan teknologi. Menurut Jumhur Ulama', salah satu syarat yang harus di penuhi bagi seorang Khalifah (kepala negara) adalah laki-laki. Hal tersebut di dasarkan pada respon Nabi SAW mendengar berita bahwa masyarakat Persia telah memilih putri Kisra sebagai pemimpin, kemudian Nabi bersabda (tidak akan beruntung suatu kaum manakal menyerahkan urusannya kepada seorang wanita). Hadis tersebut dipahami sebagai isyarat bahwa perempuan tidak boleh dijadikan pemimpin dalam urusan pemerintahan
