Published: November 2019

Abstract
This study aims to examine the factors that influence corporate risk disclosure which consist of company type, size and profitability, as well as the impact of corporate risk disclosure itself on the firm value. Every company has different risk. Investors need to know the risks faced by the company and the strategies used to deal with them. The companies listed on the ISSI are required to conduct their business based on sharia principles. Risk disclosure is a form of applying sharia principles in business ethics. The population of this research is 265 non-financial companies listed on ISSI and published the annual report for 2015-2017. The study samples are 73 non-financial companies which are chosen by applying Slovin’s formula. The data analysis techniques are path analysis and multiple group analysis. The results show that the company type, size, and profitability have a significant impact on the corporate risk disclosure, while the corporate risk disclosure itself has a positive and significant impact on firm value. This research results can be used as a consideration for the company’s management to increase the corporate risk disclosures in the annual report as it can be a positive signal to encourage the increase in company value.

Authors: Rainarli E 
Published: November 2019

Abstract
This study aims to determine the Machine Learning Model used to predict bankruptcy. The data was conducted from the financial statements of two public companies reported by the Indonesia Stock Exchange from 2009 to 2015. This research method uses an analysis feature in which the accounting ratios are used in statistical analysis of financial statements that handle missing values, choose the correlation feature related to class, and dealing with unbalanced datasets. This problem was resolved at the beginning of the pre-processing phase. The training process uses pre-processing results to fit the data with the prediction model. Accuracy is used to measure the performance of the model in predicting bankruptcy. The result is Sequential Minimal Optimization (SMO) with linear kernel function that works best to predict 1 year before bankruptcy with an accuracy of 91.57% and SMO with Radial Basis Function (RBF) works well to predict 2 years before bankruptcy; the accuracy is 93.8%. This study shows the effect of feature selection and normalization process in making correct predictions using the SMO method.

Published: November 2019

Abstract
The purpose of the structure of these nanoparticles is characterized by Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscopy, nitrogen adsorption techniques and scanning electron microscopy. The method of this research is to analyze the elements on the surface monitored by EDAX showing that pure particles are produced by steps first produced by self-assembly routes. The results of this process are influenced by the infiltration of block copolymers into zinc precursors that make bulk formation of Zn. In another approach, the use of gelatin as a template has a large effect on morphology and structure on nanoparticles. The structure of nanoparticles synthesized by gelatin involves showing significantly improved texture morphology than zinc oxide without gelatin. The application is expected to prepare the future of nanoparticles using gelatin as a co template to become a new candidate for green material in the future. The results show that gelatin can be a new biotemplate for the synthesis of zinc oxide nanoparticles.

Published: November 2019

AbstractThis study examines the effect of bank age and bank performance on the profitability of Islamic banks. The dependent variable in this study is profitability, while the independent variables are bank age, and bank performance. In addition, profit distribution is treated as an intervening variable. The sampling method used was purposive sampling where samples were taken with the provisions of 12 Public Islamic banks that publish annual reports from 2015 to 2017. The results of the data analysis show that bank age does not have a significant effect on profit ability, but NPF (Non-Performing Financing) significant effect on profit sharing. Further, although FDR (Financing to Deposit), and CI (Cost to Income) have no significant effect on profit sharing. Finally, this study also reveals that profit sharing has a significant effect on banks profitability. The implication of theoretical and managerial practices is discussed. Building a competitive advantage to face industry 4.0, one of them with adopting technology is very important for Islamic banking to improve the performance of Islamic banks, improve efficiency and productivity, which will certainly support the performance of profitability.
Computer Science and Philosophy: In Search of a Nexus
Authors: Ishaaq U M 
Published: November 2019

Abstract
This research aims to map and analyse the nexus between philosophy and computer science: ontological and epistemological, as well as axiological aspects. It is arguably known traditionally that philosophy is regarded as the mother of all rational sciences; However, there has been little hitherto discussion about the connections between the two. On the other side, philosophy is systematic inquiry into human mind and behaviour as well in order to give the meaning in every object of study. For computer scientists, understanding the nexus between philosophy and computer science will advance the ability to think through the consequences of novel ideas and widen the perspective. This study used preliminary bibliographic study using literature research methods, which carried out by investigating various interdisciplinary studies, especially computer science and information technology in terms of philosophy and its branches. The results reveal that there are strong connection between these two disciplines, mainly in ontological, epistemological and axiological aspects. On axiological and ethical aspect, the link is very important, and philosophy has potential role in ethical problem solving that arise from within the academic discipline of computer science.

Published: November 2019

Abstract
A functional capacitive sensing device with five touch points was fabricated on the curved surfaces of polyvinyl chloride, polycarbonate and acrylonitrile butadiene styrene piping. The capacitive touch sensor points and conductive traces were printed with an Optomec™ Aerosol Jet printer using silver nanoparticle ink. We present a solution to a common problem with hybrid printed electronics of transitioning from the printed electronic components on a three-dimensional object to traditional rigid circuit board electronics. We highlight the need for CAD/CAM technology as an essential tool for printing on three-dimensional surfaces. The capacitive touch sensor library of an Arduino Uno Bard Rev 3 microcontroller enabled the detection of contact at the printed touch points. Corresponding LEDs attached to the surface of the pipe light up to indicate contact at the touch points. This hybrid printed electronic device presents a fully integrated and functioning electronic device printed on a three-dimensional surface and highlights the requirement of multidisciplinary knowledge for the field of hybrid printed electronics.
Citation Skew in Plastic Surgery Journals: Does the Journal Impact Factor Predict Individual Article Citation Rate?
Authors: Asaad Malke , Kallarackal Austin Paul , Meaike Jesse , Rajesh Aashish , de Azevedo Rafael U , Tran Nho V 
Published: November 2019

AbstractBackgroundCitation skew refers to the unequal distribution of citations to articles published in a particular journal.ObjectivesWe aimed to assess whether citation skew exists within plastic surgery journals and to determine whether the journal impact factor (JIF) is an accurate indicator of the citation rates of individual articles.MethodsWe used Journal Citation Reports to identify all journals within the field of plastic and reconstructive surgery. The number of citations in 2018 for all individual articles published in 2016 and 2017 was abstracted.ResultsThirty-three plastic surgery journals were identified, publishing 9823 articles. The citation distribution showed right skew, with the majority of articles having either 0 or 1 citation (40% and 25%, respectively). A total of 3374 (34%) articles achieved citation rates similar to or higher than their journal’s IF, whereas 66% of articles failed to achieve a citation rate equal to the JIF. Review articles achieved higher citation rates (median, 2) than original articles (median, 1) (P &lt; 0.0001). Overall, 50% of articles contributed to 93.7% of citations and 12.6% of articles contributed to 50% of citations. A weak positive correlation was found between the number of citations and the JIF (r = 0.327, P &lt; 0.0001).ConclusionsCitation skew exists within plastic surgery journals as in other fields of biomedical science. Most articles did not achieve citation rates equal to the JIF with a small percentage of articles having a disproportionate influence on citations and the JIF. Therefore, the JIF should not be used to assess the quality and impact of individual scientific work.
Reduced cooperative behavior as a cost of high testosterone in a lekking passerine bird

Published: November 2019

Abstract
Many studies have identified the reproductive benefits of cooperative behaviors, yet few have identified the mechanisms that underlie these behaviors. Mechanistic studies can inform our understanding of why some individuals are more or less cooperative, as well as identify the physiological constraints imposed upon the evolution of reproductive traits. Male wire-tailed manakins (Pipra filicauda) exhibit cooperative courtship behaviors and more cooperative territory holders have been shown to exhibit higher reproductive success. To begin to understand the proximate basis of cooperative display behaviors, we conducted both an observational study and an experimental study. Because coordinated courtship displays underlie this form of cooperation, our study also examined both the hormonal and social drivers of individual variation in courtship behavior more broadly (e.g., courtship display rates). Our observational study revealed that males with higher testosterone levels performed fewer cooperative display bouts. In addition, our experimental study demonstrated that the proportion of a male’s courtship displays that were cooperative decreased after being administered a testosterone-filled hormone implant. We found no relationship between an individual’s courtship display effort (i.e., display rate and time spent performing courtship displays) and circulating testosterone in either study. However, more cooperative males spent a greater proportion of time performing courtship displays than did less cooperative males, suggesting that testosterone may indirectly mediate courtship display behaviors by influencing a territory holder’s cooperative behavior. Overall, both our observational and experimental results suggest that reduced cooperative behavior is a cost of maintaining high levels of testosterone for territory-holding males.
Evaluating a pattern of ecological character displacement: charr jaw morphology and diet diverge in sympatry versus allopatry across catchments in Hokkaido, Japan

Published: November 2019

AbstractSimilar species that overlap in sympatry may diverge in characters related to resource use as a result of evolution or phenotypic plasticity. Dolly Varden charr (Salvelinus malma) and whitespotted charr (S. leucomaenis) overlap along streams in Hokkaido, Japan, and compete by interference for invertebrate drift-foraging positions. Previous research has shown that as drift declines during summer, Dolly Varden shift foraging modes to capture benthic prey, a behaviour facilitated by their subterminal jaw morphology. We compare body and jaw morphology of Dolly Varden in sympatry vs. allopatry in two locations to test for character displacement. Statistical analysis showed significant divergence in characters related to foraging, which was correlated with variation in individual charr diets. Dolly Varden in sympatry had shorter heads and lower jaws than in allopatry, and even within sites charr with these characteristics fed less on drifting terrestrial invertebrates but more on benthic aquatic invertebrates. Those in allopatry had longer heads and lower jaws, and fed more on terrestrial invertebrates. The close proximity of sites in one stream suggests that Dolly Varden may display phenotypic plasticity similar to other charr, allowing rapid responses in morphology to the presence of competitors. These morphological shifts probably help them maintain positive fitness when competing with whitespotted charr in Hokkaido streams.
