The problem of text mining has been well studied and numerous approaches are analyzed towards their performance in text mining. The existing methods suffer to achieve higher performance as they consider only content of document and the term features available. Also, they measure the similarity between documents on the term features to identify the class of any document. This affects the performance of text mining and produces poor accuracy and generates higher irrelevancy. To improve the performance, a Conceptual Informative Relational Model (CIRM) is presented in this paper. Unlike previous methods, the method considers both conceptual and informative relations in measuring the similarity between the documents. The method preprocesses the text documents by eliminating the stop words, stemming and identifies list of root words or nouns. The root words extracted has been used to measure the conceptual relation and informative relation according to the taxonomy of classes and semantic meanings. Based on the value of relational measures, the method identifies the class of the document and produces result set. The proposed method improves the performance of text mining and reduces the irrelevancy.

السلوك الجمعي في المجتمع العراقي تعرض إلى ما يمكن تسميته بالمؤامرة ،إذ تعامل الأمويون مع ذلك المجتمع بحذر وحقد في آن واحد، تمخض عن إلصاق بعض التهم به  لغرض تسقيطه سياسيا واجتماعيا ،كونه يمثل الجهة المعارضة للسلطة الأموية، والبيئية الحاضنة للحركات المعارضة وهي كثرة بدأت من ثورة الإمام الحسين بن علي (عليه السلام ) وصولا إلى ثورة زيد بن علي مرورا بحركات مصعب بن الزبير والمختار الثقفي وثورة عبد الرحمن بن الأشعث وغيرها، وكلها كانت البيئة العراقية هي الحاضنة لها . ومن هنا تم أشاعه مثلب يقلل من شان السلوك الجمعي العراقي، والمثلب هو مقولة (يا أهل العراق يا أهل الشقاق والنفاق ومساوئ الأخلاق ) هذه المقولة حاول الأمويون أن ينسبوها إلى الإمام علي بن أبي طالب ( عليه السلام)، والكل يعرف قيمة وأهمية الإمام علي كونه احد رجالات الإسلام العظام وبهذه المقولة أراد الأمويون إيصال رسالة مفادها أن أهل العراق هم أهل شقاق ونفاق والكلام للإمام علي بن أبي طالب، وهذا يعني أن الكلام يحمل من المصداقية والدقة الشيء الكثير، إن لم يكن كله مصداقية على الإطلاق، في هذا البحث تم مراجعة مصادر التاريخ والوقوف على المقولة أعلاه، ومن قالها، وقد تبين أن المقولة هي من بنات أفكار الوالي، الحجاج بن يوسف الثقفي والي العراق الذي عينه الخليفة الأموي عبد الملك بن مروان بعد تمكن الأول من السيطرة على تمرد عبدا لله بن الزبير في مكة عام 73هـ، فكافاه وعينه واليا على العراق، وأطلق يديه بالتعامل مع العراقيين بالطريقة التي يراها ملائمة، وهكذا بدأت خطبته الأولى مع العراقيين ، وهو يتسلم منصبه السياسي الجديد مخاطبا العراقيين في الكوفة بقوله ( يا أهل العراق يا أهل الشقاق والنفاق ومساوئ الأخلاق ) وبذلك أصبحت المقولة أعلاه مدوية ومؤثرة أضاف لها الأمويون طعما آخر حين نسبوها فيما بعد للإمام علي بن أبي طالب ( عليه السلام ) كي تأخذ صداها بين الناس بشكل عام للتقليل من الشأن العراقي المعارض للأمويين، والأسباب دائما سياسية .

Probabilistic Voltage Stability Assessment Considering Variability of Wind Power
Authors: Sarkar Moumita , Hansen Anca Daniela , Sørensen Poul Ejnar
Published: January 2020

Traditional voltage stability assessment methods do not include temporal variation of renewable power generations like wind. This paper proposes a novel methodology for probabilistic voltage stability assessment methodology which can be used in conjunction with any of the existing traditional voltage stability indices. Historical wind power data are used to determine probabilistic distribution of wind power at future instant based on wind power value at current instant. Based on the probabilistic risk of increase and decrease of wind power at future instant, two probabilistic voltage stability indices are computed. The worse case value among the two indices are used as prediction of voltage stability index at future instant, based on current system parameters. Effectiveness of the proposed methodology in predicting proximity of the system voltage collapse is illustrated through case studies and time-series simulations. Results show that proposed methodology predicts more realistic proximity to voltage collapse than traditional stability assessments.

Published: January 2020

The objective of this work was to evaluate the effect of different doses of silicon on the production of lettuce seedlings. The treatments were arranged in a 4x2 factorial scheme, totaling 8 treatments. The first factor corresponded to 4 Si doses (Ca silicate) added to the substrate for seedling production (0; 13.3; 32.3 and 53.2 g.kg-1 of Si on the substrate). The second factor corresponded to two varieties of lettuce, being Mônica SF31 (Crespa) and Rafaela (Americana). The experimental design was the completely randomized, with 4 replicates. The number of leaves (NF), fresh aerial mass (MFPA), dry shoot mass (MSPA), fresh radicular mass (MFRA) and root dry mass (MSRA) were evaluated. Data were submitted to analysis of variance by the F test, and the means of the treatments compared by the Tukey test at 5% probability. The seedlings of the Mônica SF31 and Rafaela lettuce varieties do not present differences regarding the Si requirement for the production of MFPA, MSPA, MFRA and MSRA. The application of Si to the substrate can be a viable alternative for the production of lettuce seedlings with higher NF, MFPA, MSPA, MFRA and MSRA. Doses of 32.0 to 43.7 g.kg-1 of Si in the substrate are suitable for higher production of MFPA, MSPA, MFRA and MSRA of lettuce Mônica SF31. Doses of 31.5 to 39.8 g.kg-1 of Si in the substrate are suitable for higher production of MFPA, MSPA, MFRA and MSRA of Rafaela lettuce seedlings.

Risiko operasional adalah risiko  kerugiandalam bentuk  ketidakcukupan atau kegagalan proses internal, yang terkait dengan manusia dan sistem, atau risiko eksternal. risiko operasional juga meliputi risiko kegagalan teknologi, sistem dan model analitis. Risiko operasional lebih signifikan bagi bank syariah  karena fitur perjanjian mereka yang khusus dan lingkungan hukum umum.  Beberapa  aspek khusus dari perbankan syariah dapat meningkatkan risiko operasional dari bank syariah di antaranya : Risiko pembatalan dalammurabahah tidak terkait (kemitraan) dan perjanjian istisnah (manufaktur), kegagalan system pengendalian internal untuk mendeteksi dan mengelola potensi permasalahan dalam proses operasional dan fungsi back-office, potensi kesulitan dalam menegakkan perjanjian Islam dalam lingkungan hukum yang lebih luas, seringkali perlu untuk memelihara dan mengelola persediaan komoditas dalam pasar yang tidak likuid, kegagalan untuk mematuhi persyaratan syariat, potensi biaya dan risiko dalam memantau perjanjian berjenis ekuitas dan risiko hukum terkait.

Risiko operasional lain yang dapat menimpa Perbankan Syari’ah adalah fitur yang berbeda dari instrumen keuangan syariah memerlukan pengendalian dan system tekonogi informasi yang lebih mendalam. Kepatuhan terghadap syariah juga menuntut pengendalian dan pengawasann yang klebih baik.Risiko komersial displaced juga dianggap sebagai risiko khusus bagi bank syariah yang terpapar atas risiko membayar laba dari ekuitas dalam periode ketika laba actual lebih rendah daripada yang diharapkan. Risiko penarikan menghadapkan bank kepada risiko kehilangan simpanan kepada competitor yang berasal dari bank syariah lain atau bank konvensional ketika tingkat pengembalian actual lebih rendah dari yang diharapkan atau tingkat pengembalian yang ditawarkan competitor. Di samping itu, Kurangnya standardisasi dari dewan syariah di Negara-negara yang berbeda dan tantangan dalam mematuhi syariat  menghadapkan bank pada risiko syariat

A Study of the Association between Macro-Economic Variables and Stock Return
Authors: Hafeez Irfan , Nadeem Muhammad
Published: January 2020

This research points out the extending effects on stock returns
by macroeconomic variables for the period of January 2004 to December 2012.
Macroeconomic variables include foreign direct investment, exports of goods
and services, GDP, net inflows, Industry - value added, Use of IMF credit,
Lending interest rate, consumer prices, Money and quasi money growth and
inflation. The results were analyzed using the study of co-integration by
Johansen and the analysis of causality by Granger. A long-term
vigorous relationship is found between stock returns and chosen
macroeconomic variables. Unidirectional Granger causality between two
macroeconomic variables and stock returns is also observed. Impulse response
analysis shows that every variable except foreign direct investment effects stock
returns in one way or another. The results reveal that macroeconomic variables
can be studied to determine stock market return movements. The effect of
macroeconomic variables on stock market returns and capital market
sustainability when designing policies should be considered by policymakers
and investors.

CuO chemically interacted with tourmaline via Si-O-Cu bond. The specific surface area of the CuO/tourmaline composite (23.60 m2 g-1) was larger than that of pristine CuO (3.41 m2 g-1). Three predominant reactive species of superoxide radical (O2
•-), hydroxyl radical (•OH), and h+ were generated by the CuO/tourmaline composite aqueous suspension system under light irradiation. The CuO/tourmaline composite exhibited excellent photocatalytic capacity for the decomposition of organic pollutants, which was ascribed to the increase in the quantity of adsorption-photoreactive sites and the efficient utilization of photoinduced charge carriers benefited from tourmaline. This study offered a facile strategy for the construction of 0D/2D CuO structure and the design of tourmaline-based functional composite photocatalysts for the treatment of organic contaminants in waster.

The characterization of rocky, Earth-like planets is an important goal for future large ground- and space-based telescopes. In support of developing an efficient observational strategy, we have applied Bayesian statistical inference to interpret the albedo spectrum of cloudy true-Earth analogs that include a diverse spread in their atmospheric water vapor mixing ratios. We focus on detecting water-bearing worlds by characterizing their atmospheric water vapor content via the strong 0.94 μm H2O absorption feature, with several observational configurations. Water vapor is an essential signpost when assessing planetary habitability, and determining its presence is important in vetting whether planets are suitable for hosting life. We find that R = 140 spectroscopy of the absorption feature combined with a same-phase green-optical photometric point at 0.525–0.575 μm is capable of distinguishing worlds with less than 0.1× Earth-like water vapor levels from worlds with 1× Earth-like levels or greater at a signal-to-noise ratio of 5 or better with 2σ confidence. This configuration can differentiate between 0.01× and 0.1× Earth-like levels when the signal-to-noise ratio is 10 or better at the same confidence. However, strong constraints on the water vapor mixing ratio remained elusive with this configuration even at a signal-to-noise of 15. We find that adding the same-phase optical photometric point does not significantly help characterize the H2O mixing ratio, but does enable an upper limit on atmospheric ozone levels. Finally, we find that a 0.94 μm photometric point, instead of spectroscopy, combined with the green-optical point, fails to produce meaningful information about atmospheric water content.

The Kepler Space Telescope observed over 15,000 stars for asteroseismic studies. Of these, 75% of dwarfs (and 8% of giants) were found to show anomalous behavior, such as suppressed oscillations (low amplitude) or no oscillations at all. The lack of solar-like oscillations may be a consequence of multiplicity, due to physical interactions with spectroscopic companions or due to the dilution of oscillation amplitudes from “wide” (AO detected; visual) or spectroscopic companions introducing contaminating flux. We present a search for stellar companions to 327 of the Kepler asteroseismic sample, which were expected to display solar-like oscillations. We used direct imaging with Robo-AO, which can resolve secondary sources at ∼0.″15, and followed up detected companions with Keck AO. Directly imaged companion systems with both separations of ≤0.″5 and amplitude dilutions >10% all have anomalous primaries, suggesting these oscillation signals are diluted by a sufficient amount of excess flux. We also used the high-resolution spectrometer ESPaDOnS at the Canada–France–Hawai’i Telescope to search for spectroscopic binaries. We find tentative evidence for a higher fraction of spectroscopic binaries with high radial velocity scatter in anomalous systems, which would be consistent with previous results suggesting that oscillations are suppressed by tidal interactions in close eclipsing binaries.
Testing the Cosmic Distance Duality Relation with the Latest Strong Gravitational Lensing and Type Ia Supernovae
Authors: Lyu Meng-Zhen , Li Zheng-Xiang , Xia Jun-Qing
Published: January 2020

We perform a model-independent and comprehensive test on the cosmic distance duality relation (CDDR) by combining the latest observations of strong gravitational lensing (SGL) including a total of 161 well-measured systems from several surveys and observations of Type Ia supernovae (SNe Ia), i.e., the joint light-curve analysis of SNe Ia and the Pantheon SNe Ia. We parameterize the CDDR in the form of

, and also consider general lens mass models including the dependence on the lens redshift and surface mass density. First, we update tests using the new SGL and the two SNe Ia data sets for the singular isothermal sphere model. The constraint results suggest a moderate tension with the CDDR using the Pantheon SN Ia with a slightly negative η
0. We find that η
0 deviates significantly from the CDDR at more than the 3σ level if the lens mass model depends on redshift. Supplementary tests show that the error from aperture correction and the parameterization method of the CDDR can hardly justify the deviation. Several of the models investigated show some evidence for deviations from the CDDR. However, there is a significant scatter in the inferred level of the CDDR violation, depending on the model describing the population of strong lenses. This variance is too large for us to conclude yet that the CDDR is violated and needs further investigation and future measurements to be verified.
On Post-starburst Galaxies Dominating Tidal Disruption Events
Authors: Cen Renyue
Published: January 2020

A starburst induced by a galaxy merger may create a relatively thin central stellar disk at radius ≤100 pc. We calculate the rate of tidal disruption events (TDEs) by the inspiraling secondary supermassive black hole (SMBH) through the disk. With a small enough stellar velocity dispersion (

) in the disk, it is shown that 105–106 TDEs of solar-type main-sequence stars per post-starburst galaxy (PSB) can be produced to explain their dominance in producing observed TDEs. Although the time it takes to bring the secondary SMBH to the disk apparently varies in the range of ∼0.1–1 Gyr since the starburst, depending on its landing location and subsequently due to dynamical friction with stars exterior to the central stellar disk in question, the vast majority of TDEs by the secondary SMBH in any individual PSB occur within a time span shorter than ∼30 Myr. Five unique testable predictions of this model are suggested.
Le partage de la rente pétrolière au Congo dans un jeu à somme constante

Published: January 2020

L’asymétrie de l’information dans les contrats de partage de la rente pétrolière nous amène à nous interroger sur la stabilité dans le temps de l’équilibre contractuel entre le Congo et les compagnies pétrolières internationales. Deux types de contrats de partage de la rente pétrolière sont formalisés pour inciter le Congo par sélection adverse, d’en choisir un en fonction des fluctuations du prix du baril de pétrole. Quand le prix du baril de pétrole est inférieur à 15$, le contrat de concession est privilégié, au-delà jusqu’à 35$, le contrat de partage de production est choisi. Le régime actuel est celui de partage de production avec un équilibre de Nash en stratégies dominantes, pures et de duel, qui serait instable à cause des menaces crédibles des risques liés à l’aléa moral des compagnies pétrolières, du cost-oil, aux fluctuations des cours mondiaux, des préfinancements pétroliers, de l’incontestabilité des marchés pétroliers, de la mauvaise formalisation du partage, de la malédiction des ressources naturelles, qui aggravent l’asymétrie de l’information et la vulnérabilité du Congo qui connait des graves crises socio-économique et financière.
Déterminants de la réticence au marché de la finance islamique au Cameroun
Authors: Ngaha Roméo Parfait , Binam Ferdinand François
Published: January 2020

L’objectif principal de cette étude est de comprendre les facteurs explicatifs de la réticence des agents économiques camerounais (les professionnels de la finance et les clients potentiels des produits et services financiers islamiques) envers la finance islamique. Plusieurs théories ont été mobilisées pour appréhender ces déterminants, notamment la théorie de la diffusion des innovations, la théorie du cycle de vie du produit, et la théorie de la résistance au changement. Les résultats de la régression logistique mobilisée dans le cadre de cette étude montrent que des raisons psychologiques, organisationnelles et juridiques expliquent la réticence des agents économiques camerounais envers la finance islamique ; tandis que l’influence des raisons politiques et économiques est moindre et non significative sur cette attitude vis-à-vis de cette forme d’intermédiation financière. Par ailleurs, il apparaît que la mesure à adopter dans le cas du Cameroun pour une meilleure attitude vis-à-vis de la finance islamique reste la sensibilisation des acteurs économiques et du public en général sur ce phénomène.

Published: January 2020

ABSTRACT

Valid and comprehensive nursing informatics (NI) competencies currently are lacking. Meanwhile, nursing leaders are emphasizing the need to include NI in nursing curricula, as well as within the roles of practicing nurses in all settings. This article presents the initial work of a team of NI experts toward development of a valid and reliable set of NI competencies. Previous work primarily has focused on computer-related skills, rather than examining a broad definition of informatics competencies. For this current work, NI competencies encompass all skills, not only computer-related skills, as well as knowledge and attitudes needed by nurses. The first two authors created a database of NI competencies from the existing literature. A larger panel of NI experts then affirmed, modified, added, or deleted competencies from this database. Competencies were placed into four distinct skill levels. Definitions of each skill level and an initial master list of competencies are provided.

Published: January 2020

3D scanners are supporting technology which offers a higher level of flexibility to create designs for ergonomic tooling, biocompatible surgical guides, and realistic prototypes and parts. Flexibility helps to reduce lead time, weight, cost, and product development time. Scanning technologies are in tandem with support software that helps a designer to (re)design products at a cheaper and faster rate. There is a need to understand different types of flexibilities and associated application of 3D scanner. In this article, we have conducted an extensive review of the available literature for identifying various flexibilities of 3D scanners and its applications. This research categorises 3D scanner flexibility and applications into five major types. From design to final quality inspection, these flexibilities play a significant role in industries and sectors to achieve optimum performance. Ranking of these flexibilities and their impact on different applications are accomplished using the analytical hierarchical process (AHP) with the help of expert opinion. The ranking of five significant flexibilities by using 3D scanners, undertaken through the AHP technique shows that scanning provides object flexibility at a higher level. The impacts of different flexibilities on applications are also weighted, and it shows that all flexibilities are enough to achieve application individually. This digital technology is helpful to create the customised product which is also helpful to achieve goals of Industry 4.0. It facilitates the customisation and has a significant impact on the design applications. This study provides an understanding of the 3D scanner in the context of flexibilities by identifying the different flexibilities it offers when used for different applications. Findings may assist developing a decision support system for the selection of 3D scanners for the different applications.
