The Effect of Local Tournament Incentives on Firms' Performance, Risk-Taking Decisions, and Financial Reporting Decisions
Authors: Ma Matthew , Pan Jing , Stubben Stephen R.
Published: July 2019

This study documents the existence of local employment preferences for corporate executives and examines how the compensation of executives' local peers affects their own performance, risk-taking decisions, and financial reporting decisions. We find that external hires of new CEOs (CFOs) are five (eight) times more likely to be from local firms than non-local firms. We also find that local tournament incentives—as proxied by the pay gap between an executive and higher-paid executives in the area—are associated with stronger performance, greater risk taking, and more financial misreporting. We find consistent results using a difference-in-differences analysis that exploits plausibly exogenous variation in local tournament incentives caused by the sudden death of a local CEO. Our findings are consistent with executives taking actions to compete for a promotion to a nearby firm with higher pay.
Long-Term Orientation and Earnings Management Strategies
Authors: Haga Jesper , Huhtamäki Fredrik , Sundvik Dennis
Published: July 2019

In this study, we investigate how country-level long-term orientation affects managers' willingness to engage in earnings management and choice of earnings management strategy. Using a comprehensive dataset of 47 countries for the period from 2003 to 2015, we find that firms in long-term-oriented cultures rely relatively more on earnings management through accruals, while firms in short-term-oriented cultures engage in relatively more real earnings management. Furthermore, we find a larger discontinuity around earnings benchmarks in long-term-oriented cultures suggesting that manipulation of accruals enables benchmark beating with high precision.

Experimental and statistical study on kerf taper angle during CO2 laser cutting of thermoplastic material
Authors: Varsi Arif M. , Shaikh Abdul Hafiz
Published: July 2019

CO2 laser machining is an advanced material processing technology, gaining more popularity due to its low cost and rapidity as well as good cutting quality depending on the material and its properties. Polymethylmethacrylate (PMMA) is found to be one of the most suitable thermoplastics for CO2 laser machining due to its higher melting point and higher absorptivity at the CO2 laser wavelength. The kerf taper angle is one of the most important quality characteristics because it is one of the measures for the geometrical accuracy of the machined cavities. The present work deals with the CO2 laser (0–25 W) cutting of 8 mm thick PMMA material. The influence of process parameters like power, speed, and a number of passes of the laser probe is examined on the kerf taper angle. The regression analysis has been done to develop a model that studies the effect of process parameters on the kerf taper angle which is one of the important cutting quality characteristics. Experiments were carried out using the full factorial methodology, and the cylindrical blind cavities were machined for different combinations of parameters. It is found that power, speed, and a number of passes have a significant effect on the kerf taper angle. Higher laser power, lower speed, and higher number of passes of laser probe result in low kerf taper. The statistical model developed can be used for the selection of process parameters for process control.

Authors: Ma Leo F.H. , Yu Ling Ling
Published: July 2019

Library services for Hong Kong-based students enrolled in distance learning programs on information studies, offered by the Charles Sturt University (CSU), Australia in collaboration with the School of Professional and Continuing Education of the University of Hong Kong (HKUSPACE), were supported by the University of Hong Kong Libraries utilizing a face-to-face format for many years. With the advancement of internet technology, new e-learning software, mobile technology and ever-growing online resources, CSU and HKUSPACE course administrators considered that online library instruction programs could be supported and delivered by the librarians of CSU at Australia remotely to Hong Kong students. Several real-time, online instruction programs were initiated since late 2013. The successful launching of the programs provides evidence to support the provision of online library instruction through not only personal computers, but also mobile devices. Based on a qualitative analysis, it was concluded that delivering library instruction programs by internet and mobile technology to distance learning students in higher education is achievable. More library services can be planned by making use of this successful experience.

ASPEK HUKUM PERKAWINAN ANTAR AGAMA DAN PROBLEMATIKA YURIDISNYA
Authors: Erwinsyahbana Tengku
Published: July 2019

Perkawinan antar agama diasumsikan akan terus terjadi sebagai akibat interaksi sosial di antara seluruh warga negara Indonesia yang pluralis agama, dan hal ini masih menimbulkan permasalahan yuridis, terutama terkait dengan pencatatan perkawinan tersebut, karena walaupun pasangan suami istri telah melangsungkan perkawinan, KUA atau KCS dapat menolak untuk mencatatkan atau menolak untuk mengeluarkan akta perkawinannya. Perkawinan yang tidak dicatatkan akan menyebabkan status hukum pihak-pihak dalam perkawinan menjadi tidak pasti, dan perkawinan tersebut akan menimbukan problematika yuridis lainnya, yaitu: (1) hilangnya kewajiban ayah untuk mengasuh, mendidik, memelihara ataupun menafkahi anak/anak-anak yang lahir dari perkawinan itu, karena secara yuridis ayah dan anak/anak-anak tidak mempunyai hubungan yang bersifat keperdataan; (2) ketidakpastian hukum terhadap kedudukan istri dalam perkawinan, sehingga istri dapat saja kehilangan hak-haknya dalam rumah tangga, misalnya hak atas nafkah dari suami ataupun hak untuk mewarisi harta peninggalan suaminya, jika suami lebih dahulu meninggal dunia; (3) harta benda yang diperoleh selama dalam perkawinan (harta bersama) dianggap tidak ada, dan ketika terjadi perceraian, masing-masing pihak tidak dapat saling menuntut untuk diadakannya pembagian terhadap harta bersama; dan (4) anak/ anak-anak yang lahir dari perkawinan itu dianggap sebagai anak yang tidak sah, dengan demikian hanya mempunyai hubungan keperdataan dengan ibunya dan keluarga ibunya.

Dichos resultados pueden ser considerados para el diseño de tareas específicas de entrenamiento de la colocación, acordes a diferentes situaciones de juego.
A Refugee Crisis Without Refugees: Policy and media discourse on refugees in the Czech Republic and its implications
Authors: Jelínková Marie
Published: July 2019

Along with other Central and Eastern European counties, Czechia has invested significant effort in deterring refugees from entering the country during the ‘refugee crisis’. This article sheds light on the role of the media in legitimising anti-refugee policies by analysing the politicised discourse on refugees in 900 articles published in Czech newspapers between 2014 and 2016. The findings indicate that refugees were depicted as a security threat and an administrative burden partly imposed by the European Union. The article discusses the policy implications of depicting refugees in this way and thus broadens the literature on European narratives during the refugee emergency in Europe.

Published: July 2019

Petroleum and natural gas still have their place among the most important resources in many industrial areas. Their global consumption influences an increasing demand on the quality of drilling works and the efficiency of extraction. Nonetheless, even in this field of human activity, we can encounter exceptional events and accidents. One of the most serious kinds of accidents during exploration is the so called open eruption of extracted medium. The specific case of this accident is an open eruption caused by drilling tools when a working crew is not capable of securing drilling workplace. In order to solve this emergency situation, Main Mining Rescue Station Hodonin (HBZS Hodonin), in cooperation with researchers from Faculty of Mining and Geology at VSB - Technical University of Ostrava, designed and developed specialised apparatus DPRP (Drill Pipe Rescue Press), working designation FIB-1. This apparatus enables the liquidation of eruption by pressing the drilling pipe. The residual crack, which remains following the pressing, must be eliminated by sealing materials. This paper reviews the testing of sealing elements (materials), designed by our team, in residual crack of circle shape with help of hydraulic press MTS 816 Rock Test System.

Advancements in neural machinery have led to a wide range of algorithmic solutions for molecular property prediction. Two classes of models in particular have yielded promising results: neural networks applied to computed molecular fingerprints or expert-crafted descriptors, and graph convolutional neural networks that construct a learned molecular representation by operating on the graph structure of the molecule. However, recent literature has yet to clearly determine which of these two methods is superior when generalizing to new chemical space. Furthermore, prior research has rarely examined these new models in industry research settings in comparison to existing employed models. In this paper, we benchmark models extensively on 19 public and 16 proprietary industrial datasets spanning a wide variety of chemical endpoints. In addition, we introduce a graph convolutional model that consistently matches or outperforms models using fixed molecular descriptors as well as previous graph neural architectures on both public and proprietary datasets. Our empirical findings indicate that while approaches based on these representations have yet to reach the level of experimental reproducibility, our proposed model nevertheless offers significant improvements over models currently used in industrial workflows.

The Marcus cross relation has been used for outer sphere electron transfer, proton transfer, hydride transfer, and proton-coupled electron transfer. This work shows that the same Marcus cross relation is useful in determining rate constants for inner sphere reduction of molecular oxygen. This has many implications in the field of small molecule activation in the form of catalyst design and as an indirect mechanistic probe.
Investigating the Effect of Positional Isomerism on the Assembly of Zirconium Phosphonates Based on Tritopic Linkers
Authors: Taddei Marco , Shearan Stephen J. I. , Donnadio Anna , Casciola Mario , Vivani Riccardo , Costantino Ferdinando
Published: July 2019

We report on the use of a novel tritopic phosphonic linker, 2,4,6-tris[3-(phosphonomethyl)phenyl]-1,3,5-triazine, for the synthesis of a layered zirconium phosphonate, named UPG-2. Comparison with the structure of the permanently porous UPG-1, based on the related linker 2,4,6-tris[4-(phosphonomethyl)phenyl]-1,3,5-triazine, reveals that positional isomerism disrupts the porous architecture in UPG-2 by preventing the formation of infinitely extended chains connected through Zr-O-P-O-Zr bonds. The presence of free, acidic P-OH groups and an extended network of hydrogen bonds makes UPG-2 a good proton conductor, reaching values as high as 5.7x10-4 S cm-1.

This study tries to describe the meaning of multiculturalism family on the WhatsApp group for the family members. This study is qualitative type using virtual ethnographic approach to describe the reality. The results of the study reveal that the experience of communication experienced is referred to as an archipelago insight experience. Cultural intelligence is assessed from the personal activeness of family members and information shared. When talking about something outside of its cultural values, there are some of the family members who choose to be silent, there are some who choose to ask questions to understand, but there are some who directly express their feelings. Communication culture can also be seen from the personal activeness of each members, there is a silent reader, some respond when needed, some are positioned as followers and some are dominant.

The employment of FTIR spectroscopy and chemometrics for authentication of
pumpkin seed oil from sesame oil
Authors: Irnawati  , Riyanto S. , Martono S. , Rohman A.
Published: July 2019

The adulteration practice of high price oils such as pumpkin seed oils (PSO) with lower
ones could be motivated by economic gains. The objective of this study was to apply
FTIR spectroscopy in combination with chemometrics of multivariate calibrations and
discriminant analysis for the authentication of PSO. A total of fifteen oils were scanned
using FTIR spectrophotometer at mid-infrared regions (4000-650 cm-1
) and subjected to
principal component analysis (PCA) using absorbance values at whole mid-IR regions to
know oil having a close similarity to PSO in terms of FTIR spectra. Two multivariate
calibrations namely principle component regression (PCR) and partial least square
regression (PLSR) along with FTIR spectra modes (normal, derivative-1, and derivative2) were optimized to get the best prediction models. In addition, discriminant analysis
(DA) was used for classification of PSO and PSO adulterated with oil adulterant. The
results showed that among 15 oils, sesame oil (SeO) had the closer score plot in terms of
the first principle component and second principle components with that of PSO. Based on
the statistical parameters selected (higher R2
and lowest errors), FTIR spectra in derivative
-1 mode at wavenumbers of 1800-663 cm-1 were selected for quantification of PSO in SeO
with coefficient of determination (R) values of 0.9998 and 0.9994 in calibration and
validation models, respectively. The values of root mean square error of calibration
(RMSEC) and root mean square error of prediction obtained were 0.003% and 0.006%,
respectively. DA using 10 principle components could clearly discriminate PSO and PSO
adulterated with SeO with accuracy levels of 100%. FTIR spectroscopy in combination
with chemometrics could be an effective means to detect the adulteration of PSO with
SeO.

El monitoreo biológico es un método para conocer la dinámica de los ecosistemas, por lo que el objetivo del proyecto de monitoreo de aves en la Reserva de la Biosfera Mapimí (RBM), Durango fue estimar la riqueza y abundancia de aves, así como su variación temporal (invernal y reproductiva). Este monitoreo lo hemos realizado de 2012 hasta 2017 en 122 puntos de conteo distribuidos en el área protegida. Identificamos especies y número de individuos visual y auditivamente durante periodos de 10 y 20 min y estimamos el porcentaje de la cobertura vegetal. Durante este periodo (5 años) registramos 149 especies de aves, siendo 2015 el de mayor número de especies observadas. La especie con el mayor número de individuos observados fue el gorrión de ala blanca Calamospiza melanocorys. Encontramos diferencias estadísticas en la riqueza (P < 0.05), número de individuos (P < 0.05) y porcentaje de cobertura vegetal (P < 0.05) de la temporada invernal y reproductiva entre los años 2012 y 2017. Entre los años 2016 y 2017 encontramos diferencias entre la riqueza de aves y número de individuos del periodo invernal (P < 0.05); mientras que no encontramos diferencias en la temporada reproductiva (P > 0.05).
Effect of Salinity on Evaporation and the Water Cycle

This study is on the effect of salinity on evaporation from water bodies and probable influence on the water cycle. Five different salts were used in this study, different concentrations of Magnesium Sulphate, Sodium Hydroxide, Sodium Chloride, Ammonium Chloride and Potassium Nitrate solutions in the neighbourhood of 0.04, 0.08, 0.12, 0.16, 0.20 and 0.24 g/cm3 were prepared by dissolving 20, 40, 60, 80, 100 and 120 g weights of these salts in 500 cm3 of distilled water. The first evaporation can contained only 500 cm3 of distilled water and served as the control experiment. The solutions were introduced in evaporation cans each of capacity 700 cm3, stored under room temperature and evaporation allowed to take place. Evaporation from the cans were measured at 24 hours intervals for a period of 14 days. Results showed that in all salts, as salinity increases, evaporation is reduced. On the 10th day, evaporation retardation factors for Magnesium Sulphate, Sodium Hydroxide, Sodium Chloride, Ammonium Chloride and Potassium Nitrate were found to be 0.800, 0.490, 0.712, 0.820 and 0.822 respectively. Ratios of evaporation retardation factors were 1:1.6327 for Sodium hydroxide : Magnesium Sulphate; 1:1.4531 for  Sodium Hydroxide : Sodium Chloride; 1:1.6735 for  Sodium Hydroxide : Magnesium Sulphate; 1:1.4531 for Sodium Hydroxide: Sodium Chloride; 1:1.6327 for Sodium Hydroxide : Ammonium Chloride and 1:1.6776 for Sodium Hydroxide : Potassium Nitrate solutions. Highest evaporation took place in Potassium Nitrate solution at the ultimate concentration of 0.24 g/cm3, this was followed by Ammonium Chloride, Magnesium Sulphate, Sodium Chloride and Sodium Hydroxide. These salinity effects will impact on the outflow parameter in the water cycle with consequent reduction in evaporation which reduces precipitation, hence the formation of rain in the cloud would be inhibited and ultimately lead to climate change.

Habitus dan Arena dalam Novel Taman Api Karya Yonathan Rahrdjo
Authors: Solissa Everhard Markiano
Published: July 2019

Karya sastra lahir dari latar belakang dan dorongan dasar manusia untuk mengungkapkan eksisitensi dirinya. Karya sastra lahir bukan dari ruang kosong melompong, tetapi dari sebuah interaksi dengan realitas kehidupan manusia. Salah satu realitas dalam kehidupan dunia kontemporer sekarang ini adalah  adanya krisis identitas dan subjektivitas. Tujuan penelitian ini adalah menemukan dan mendeskripsikan habitus dan arena dalam novel Taman Api karya Yonathan Rahrdjo. Data dikumpulkan dengan teknik pustaka. Dengan menggunakan teori medan sastra Pierre Bourdieu, ditemukan bahwa (1) novel Taman Api menggambarkan bentuk habitus atau cara pandang seseorang dalam menentukan tindakan. Habitus agen terus bergerak dari waktu ke waktu. Pergerakan itu diakibatkan oleh pengalaman, didikan, atau bahkan pergaulan; (2) arena dalam novel Taman Api berupa arena kedokteran yang dianggap arena orang berkelas. Namun demikian, dalam arena ini agen-agenya tidak mencerminkan akhlak yang baik. Arena berikutnya adalah arena bisnis di mana setiap agen berupaya menjalankan fungsi dengan sebaik-baiknya agar jaringan yang dibangun tetap bertahan untuk kepentingan bersama yaitu saling menguntungkan. Arena yang terakhir adalah arena waria. Setiap agen dalam arena ini dianggap perusak tatanan moralitas, dan sering menjadi sasaran kekerasan penguasa.

Tipong Tawar merupakan sebuah mantra yang digunakan dalam ritual-ritual adat suku Dayak Paser, Kalimantan Timur. Tipong Tawar merupakan mantra yang memiliki media berupa tepung berwarna putih dan tidak berasa yang disebut dengan tawar. Tipong Tawar sering disampaikan oleh seorang Balian (dukun/pawang) dalam ritual adat. Salah satu ritual adat tersebut adalah ritual dalam pertanian. Tujuan penelitian ini adalah mendeskripsikan bentuk dan struktur teks mantra Tipong Tawar dalam ritual pertanian Dayak Paser, Desa Baras Jiring, Kecamatan Muara Komam, Kabupaten Paser Kalimantan Timur. Jenis penelitian yang digunakan dalam penelitian ini adalah kualitatif. Menggunakan metode deskriptif serta pendekatan etnografi. Teknik pengumpulan data dilakukan melalui proses wawancara, perekaman, dan pencatatan. Hasil temuan menunjukkan bahwa bentuk dan struktur teks mantra Tipong Tawar merupakan struktur puisi karena mantra juga merupakan puisi lama dalam genre sastra. Adapun bentuk dan struktur teks mantra Tipong Tawar meliputi; tema, formula bunyi (rima dan irama), bait, baris, dan diksi. Dapat disimpulkan bahwa terkait dengan struktur pada teks mantra Tipong Tawar berdasarkan pada tema, rima, irama, bait, baris, dan diksi memang berbeda dengan struktur pada puisi pada umumnya, terutama pada diksi sebuah teks mantra. Karena diksi pada teks mantra menggunakan bahasa daerah yang tidak semua arti dalam bahasa Indonesia tidak dapat dimaknai secara harafiah. Hal ini yang membedakan mengenai diksi teks mantra dan diksi puisi pada umumnya.
