TL;DR: In this paper, the authors report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia.
Abstract: We report on tetrapod (Reptilia, Amphibia, Mammalia, Aves) vertebrates recovered during excavations at Tron Bon Lei rockshelter on the south coast of Alor Island, eastern Indonesia. These include both archaeological specimens recovered from a 1 m² test pit dating from ∼21 kya cal BP to the late Holocene, and a modern eastern barn owl deposit recovered nearby. To discern between the depositional processes that accumulated the small numbers of micro- and macrovertebrate remains from the archaeological deposits, the taphonomic signature of the natural assemblage was quantified and compared to the archaeological record. The taphonomic data indicates that the tetrapod archaeofaunal remains are a combination of barn owl predation of microfauna and human predation of larger fauna. This approach provides new information on human-tetrapod interactions on Alor in Wallacea during the late Quaternary, including an apparent increase in cave site use and hunting intensity during the Pleistocene-Holocene transit...

TL;DR: In this article, a pandangan ying menyebutkan bahwa etnisitas merupakan penghambat untuk kesatuan and persatuan negara.
Abstract: Banyak pandangan yang menyebutkan bahwa etnisitas merupakan penghambat untuk kesatuan dan persatuan. Hal penting yang menjadi tantangan ke depan adalah mendudukkan variasi etnik sebagai bentuk kemajemukan bangsa yang mendukung persatuan negara. Dengan menggunakan data Sensus Penduduk di Indonesia, yakni Sensus Penduduk 1930, Sensus Penduduk 2000 dan Sensus Penduduk 2010, tulisan ini mencoba mengungkapkan dinamika etnis di Indonesia dalam perspektif historis. Penelitian ini mendiskusikan dinamika perkembangan etnik di Indonesia serta melihat bahwa keanekaragaman etnik tersebut dapat menjadi tantangan dan pemacu dalam persatuan negara. Melalui masyarakat multikultural yang saling menghargai perbedaan kebudayaan, akan dapat tercipta masyarakat yang memiliki pandangan, jiwa, dan tujuan yang sama. Selain itu, perwujudan dari perkembangan etnik di Indonesia juga harus disertai dengan adanya dukungan kebijakan pemerintah yang tidak hanya memihak pada golongan mayoritas saja karena asas yang dikedepankan adalah persamaan dan menghargai hak atas perbedaan kebudayaan.

TL;DR: In this paper, Fourier transform infrared (FTIR) spectroscopy in combination with multivariate calibration based on partial least squares (PLS) has been developed for quantitative analysis of sunflower oil (SFO) and palm oil (PO) as oil adulterants in red fruit oil (RFO) for the authentication study.
Abstract: In this study, Fourier transform infrared (FTIR) spectroscopy in combination with multivariate calibration based on partial least squares (PLS) has been developed for quantitative analysis of sunflower oil (SFO) and palm oil (PO) as oil adulterants in red fruit oil (RFO) for the authentication study. The binary mixtures of SFO and PO in RFO were infrared spectroscopically scanned using horizontal attenuated total reflectance at mid infrared region (4000–650 cm −1 ). Some frequency regions where the variations were observed among RFO, SFO, and PO were optimized in order to seek the best frequency regions giving the best PLS calibration models. Besides, the derivatization of FTIR spectra (fisrt and second derivatives) was also investigated in order to look the types of FTIR spectra giving the best spectral performance in the model. The results showed that SFO was better determined using FTIR normal spectra at the frequency region of 1200–1000 cm −1 with coefficient of determination ( R 2 ) of >0.99 and with root mean square error of calibration (RMSEC) of 1.42% v/v. FTIR normal spectra were also more preferred than its derivative for the quantification of PO in RFO. The R 2 value obtained for the relationship between actual value (reference value) and predicted value obtained during PLS modeling is very high (0.9991) with the low level of error (RMSEC of 0.98% v/v). It can be concluded that FTIR in combination with PLS is a reliable method for quantitative analysis of SFO and PO as adulterant in RFO for authenticity verification.

TL;DR: In this paper, the authors examined the association between an information asymmetry and cost of equity capital and found that a company which has a disclosure at a greater extent will reduce the cost of the equity capital.
Abstract: This research examines the association between an information asymmetry and cost of equity capital The conventional wisdom, it is generally assumed that a company which has a disclosure at a greater extent will reduce the cost of equity capital An empirical research indicated more disclosure will reduce information asymmetri This research tries testing if the declining of information asymmetry resulting from the extent of disclosure will bring the effects on declining of the cost of equity capital Further, the research tries testing the differences of declining level of cost of equity capital as a result of the declining of information asymmetry among relatively small companies and large companies The number of companies taken as samples in the research cover about 213 companies, listed at Jakarta Stock Exchange before 1996 The hypothetical test was conducted by implementing cross-sectional method, taking a research periode of 1996 This research adopts Bid ask spread as a basis for measurement of information asymmetry and capital asset pricing model (CAPM) used to estimate the quantity of cost of equity capital In order to control the size effects, analytical model in the research also utilizes the variables of market values of equity As expected, the research showed up the existence of a positive relationship between information asymmetry and cost of equity capital A controlled-variable, NPSR, also brought effects on the number of cost of equity capital significantly This fact makes it possible to separate the hypothesis between a large company and a small one Separately, the results of testing between small scaled - companies and large scaled-companies indicated real differences at the declining level in term of cost of equity capital Large companies experience a greater declining cost of equity than small companies, therefore, a large company earned a greater benefit resulting from a greater disclosure, compared from a small company This results implied that the companies have to improve the quality of their disclosure with the intention that the information asymmetry happening among the market players will declines and so will the cost of equity capital
