Estimating Sensitive Population Proportion Using a Combination of Binomial and Hypergeometric Randomized Responses by Direct and Inverse Mechanism
Authors: Dihidar Kajal , Bhattacharya Manjima 
Published: November 2017

Abstract
For various reasons individuals in a sample survey may prefer not to confide to the interviewer the correct answers to certain potentially sensitive questions such as the illegal use of drugs, illegal earning, or incidence of acts of domestic violence, etc. In such cases the individuals may elect not to reply at all or to reply with incorrect answers. The resulting evasive answer bias is ordinarily difficult to assess. The use of a randomized response method for estimating the proportion of individuals possessing those sensitive attributes can potentially eliminate the bias. Following Chaudhuri and Dihidar (2014) and Dihidar (2016), here, as a possible variant, we have made an attempt to estimate the sensitive population proportion using a combination of binomial and hypergeometric randomized responses by direct and inverse mechanism. Along with the traditional simple random sampling, with and without replacement, we consider here sampling of respondents by unequal probabilities. Essential theoretical derivations for unbiased estimator, variance and variance estimators are presented for several sampling schemes. A numerical illustration is performed to make a comparative study of the relative efficiencies of the direct and inverse mechanism.
A Multidimensional and Dynamised Classification of Polish Provinces Based on Selected Features of Higher Education in 2002–2013
Authors: Łukaszonek Wojciech 
Published: November 2017

AbstractFor close to two decades after the fall of communism in 1989, Polish higher education enjoyed an unprecedented period of development. Favourable political, economic, social and demographic changes led to a fivefold increase in the number of students and the number of higher educational institutions. The dynamic changes and their effects did not occur uniformly, in either space or time. An attempt is made here to identify and analyse the regional differentiation between Polish provinces in terms of features relating to higher education. To investigate the changes in higher education in the period of economic and social transformation, observations were made of fundamental characteristics of higher education in the years 2002–2013. The applied procedure uses new statistical methods applicable to a space of doubly multivariate data. The covariance matrix used to construct principal components is given the structure of a Kronecker product. The results led to the identification of six groups of provinces, including two consisting of a single province – Mazowieckie and Małopolskie provinces – which contain the largest and the highest-ranked2higher educational institutions in Poland: the University of Warsaw and Jagiellonian University.

Published: November 2017

Abstract

Background and objective
In survival analysis, estimating the survival probability of a population is important, but on the other hand, investigators want to compare the survival experiences of different groups. In such cases, the differences can be illustrated by drawing survival curves, but this will only give a rough idea. Since the data obtained from survival studies contains frequently censored observations some specially designed tests are required in order to compare groups statistically in terms of survival.

Methods
In this study, Logrank, Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modified Peto-Peto tests and tests belonging to Fleming-Harrington test family with (p, q) values; (1, 0), (0.5, 0.5), (1, 1), (0, 1) ve (0.5, 2) are examined by means of Type I error rate obtained from a simulation study, which is conducted in the cases where the event takes place with equal probability along the follow-up time.

Results
As a result of the simulation study, Type I error rate of Logrank test is equal or close to the nominal value.

Conclusions
When survival data were generated from lognormal and inverse Gaussian distribution, Type I error rate of Gehan-Wilcoxon, Tarone-Ware, Peto-Peto, Modified Peto-Peto and Fleming-Harrington (1,0) tests were close to the nominal value.

<p>O objetivo deste estudo foi identificar as percepções de mães sobre a prática do aleitamento materno e da introdução da alimentação complementar. A coleta de dados ocorreu no período de novembro a dezembro de 2016 e utilizou-se de entrevista semiestruturada, com mães acompanhadas pelo Centro de Saúde e Comunidade no município de Palmas/Tocantins, tendo como eixo perguntas norteadoras, previamente elaboradas pelos pesquisadores, cujas respostas foram gravadas e posteriormente transcritas para análise dos resultados. Das entrevistadas que tiveram consulta de pré-natal, 73,91% das mães relataram receber orientações sobre a importância do aleitamento materno e alimentação complementar. Em relação à prática das orientações recebidas nas consultas de pré-natal, a mais comentada pelas mães foi sobre a pega da mama e a importância da amamentação exclusiva até 6 meses. O grupo relacionou o aleitamento materno exclusivo com a proteção à saúde da criança, além dos benefícios nutritivos do leite humano e que apesar de terem recebido orientações e informações durante as consultas de pré-natal no período gestacional, é possível observar que as mães têm conhecimento limitado referente ao aleitamento materno exclusivo até os 6 meses de idade da criança. Além disso, as entrevistadas possuem um conhecimento empírico quando analisadas as percepções sobre alimentação complementar. Existe um distanciamento entre as informações que estão sendo transmitidas sobre amamentação e alimentação complementar, que deveriam ser explicadas e trabalhadas com mais clareza por profissionais de saúde a fim de promover ações de amamentação e alimentação complementar de forma mais efetiva. </p>
Inhibition of Daphnia magna's occurrence in drinking water treatment process by controlling its phototactic behavior
Authors: Lin Tao , Tan Yiwen , Chen Wei 
Published: November 2017

Abstract
Cladocera zooplankton as carriers of bacteria result in biological risk due to their occurrence in drinking water treatment systems. In this paper, bench-scale experiments were performed to investigate the inhibition effect on Daphnia magna (D. magna) by controlling its phototactic behavior. The results showed that UVA had a negative effect on the phototaxis of D. magna, indicating an active movement away from light source, while blue light was positive in inducing phototactic behavior. The water quality could influence the phototactic behavior of D. magna. When the turbidity value was higher than 10 NTU or total organic carbon (TOC) concentration was beyond 4 mg/L, the phototaxis of D. magna to UVA (25 μw/cm2 intensity) or blue light (1,000 Lux intensity) was significantly weakened. It was difficult for D. magna to offset the effect of water flow by its phototactic movement when the flow rate was higher than 10 mm/s. According to the above results, with suitable process parameters in full-scale experiments, the occurrence of D. magna in the effluent of sedimentation tank and activated carbon filter was obviously inhibited by the UVA irradiation and blue light induction, respectively.
“Back to the Future” (Or How a Product Last Sold Almost 60 Years Ago Resulted in a Current Financial Statement Restatement)
Authors: Franz Diana R. 
Published: November 2017

ABSTRACT
Owens-Illinois (OI) restated its financial statements for the year 2015 due to a disagreement with the Securities and Exchange Commission (SEC) regarding how the firm accounted for unasserted claims related to asbestos litigation. Almost 60 years ago, OI sold approximately $40 million of a product that contained asbestos and has subsequently accrued almost $5 billion of liability related to those sales. From 2003 through 2015, OI had been estimating unasserted claims over a rolling three-year window, which the firm viewed as preferable because it improved the reliability of the resulting estimate that was important given the volatility of asbestos litigation. The SEC required that OI accrue unasserted claims for as far into the future as foreseeable. While the accounting change increased the estimate of the total liability for asbestos litigation, when it was allocated to individual years, this change materially increased OI's earnings for the years 2013, 2014, and 2015. Another interesting aspect of the change was that the SEC's required accounting treatment resulted in OI returning to the manner in which it had originally estimated asbestos liability (pre-2003).
The Incremental Informativeness of the Sentiment of Conference Calls for Internal Control Material Weaknesses
Authors: Sun Ting 
Published: November 2017

ABSTRACT
Using a deep-learning-based textual analyzer provided by IBM Watson, this paper obtains scores measuring the overall sentiment and emotion of “joy” from the transcripts of conference calls and uses them as additional predictors of internal control material weaknesses (ICMWs), combined with other determinants of ICMWs suggested by prior literature (i.e., Doyle, Ge, and McVay 2007; Ashbaugh-Skaife, Collins, and Kinney 2007). The results indicate that, with the incorporation of the sentiment features (especially the score of “joy”), the explanatory ability of the model improves significantly, as compared to that of the baseline model that merely utilizes the major ICMW determinants.

Published: November 2017

2008-ci ildə dünya ölkələrində 12.7 milyon yeni xərçəng xəstəliyi qeydə alınmış və 7.6 milyon insan xərçəngdən ölmüşdür. Həmin bədxassəli törəmələrin bir çoxunun qarşısının alınmasının mümkünlüyünə dair çoxsaylı sübutların olduğunu nəzərə alsaq, qeyd olunmuş statistikanın nə dərəcədə sarsıdıcı olduğu aydın görünür. Xərçəng diaqnozu qoyulmuş xəstələr arasında sağqalma halları artsa da, ölənlərin sayı hələ də çoxdur. Məsələn, ABŞ-da hər il yarım milyondan çox insan xərçəng səbəbindən ölür. ABŞ-da yaşı 85-dən aşağı olan əhali arasında baş verən ölüm hallarının aparıcı səbəbi məhz xərçəng xəstəliyidir. Ölümün səbəblərinə görə ABŞ-da xərçəng ürək-damar xəstəliklərini artıq üstələyibdir.
Həm skrininq, həm də profilaktik tədbirlər xərçəng xəstəliyindən ölüm hallarını azalda bilər. Skrininq tədbirləri xərçəng önü anomaliyaların/dəyişikliklərin aşkar edilməsi və ya xərçəng xəstəliklərinin çox erkən mərhələlərdə müəyyən edilməsinə və beləliklə müalicənin daha effektiv olmasına kömək edir. Profilaktik strategiyalar isə xərçəngin inkişafına şərait yaradan və ya təsir edən həyat tərzi və ətraf mühitlə bağlı risk faktorların modifikasiyasına yönəlib. Təhlillər göstərir ki, bütün xərçəng xəstəliklərinin 50%-nin qarşısı alına biləndir.
Xərçəng xəstəliklərinin inkişafına təsir edən çoxsaylı risk faktorları müəyyən edilib: tütünçəkmə, artıq bədən çəkisi, qeyri-sağlam qidalanma və fiziki aktivliyin çatışmazlığı. Araşdırmalardan müəyyən edilib ki, modifikasiya oluna bilən 9 risk faktoru dünyada baş verən bütün xərçəng hallarının 35%-na səbəb olur. Bu 9 risk faktoruna aşağıdakılar aiddir: tütünçəkmə, spirtli içkilərdən istifadə, meyvə və tərəvəz tərkibi az olan pəhriz, artıq çəki, fiziki passivlik, müdafiəsiz cinsi əlaqə, şəhərlərdə havanın çirklənməsi, bərk yanacaqların istifadəsi və tibb müəssisələrində yatrogen yayılma. Xərçəngin Tədqiqi üzrə Beynəlxalq Agentlik tərəfindən insanlarda xərçəng xəstəliyinə səbəb olan 100-dən çox karsinogen müəyyən edilibdir. 2015-ci ildə qırmızı ət də karsinogenlər siyahısına daxil edildi.
Həyat tərzi ilə bağlı faktorlar müxtəlif bədxassəli törəmələrin inkişafı ilə bağlıdır. İnkişaf etmiş ölkələrdə bu bağlılıq xüsusilə də, ağciyər, kolorektal, prostat vəzi və süd vəzi xərçənglərinin inkişafında özünü biruzə verir.
PERKEMBANGAN PERBANKAN BAGI HASIL DI INDONESIA
Authors: Utami Wikan Budi 
Published: November 2017

Anjloknya nilai tukar mata ung lokal yang diakibatkan adanya krisis ekonomi, menyebabkan bank-bank konvensional yang memberlakukan sistem bunga dan menganggap uang bukan hanya sekedar berfungsi sebagai alat tukar melainkan telah menjadi barang komoditas, sehingga mereka menaikkan secara besar-besaran bunga pinjaman dan simpanannya. Tingginya tingkat bunga tersebut menyebabkan ekonomi kekurangan likuiditas, yang akibatnya dunia usaha menjadi stagnan, sehingga akhirnya bangkrut dan berakibat meningkatnya pengangguran. Walhasil masyarakat semakin miskin. Di sisi lain bank harus membayar bunga deposito yang tinggi, sedangkan pendapatan bunganya anjlok karena kredit macet. Akhirnya banyak bank-bank konvensional berbasis bunga, satu per satu gugur terlikuidasi. Dalam keadaan demikian terbukti bank syariah yang non bunga tapi bersistem bagi hasil (profit sharing)-lah yang bisa tetap bertahan terhadap tekanan krisis ekonomi. Hal ini disebabkan karena konsep yang mendasari sistem keuangan syariah, menganggap uang hanya sebagai alat tukar. Sehingga uag tersebut tidak akan menghasilkan nilai tambah apapun, kecuali apabila dikonversi menjadi barang atau jasa. Sehingga tiap transaksi keuangan harus dilatarbelakangi transaksi sektor riil.

Published: November 2017

AbstractIn this study optimization of extraction conditions for saponin from soapnut (Sapindus mukorossi) has been investigated. This investigation showed that a better extraction of saponin can be achieved with increasing the dielectric constant of solvent employed. The best yield was attained in a 50% v/v aqueous ethanol medium. Another objective of the present study is to assess the thermodynamics of the uptake-reduction of hexavalent chromium in contaminated water samples using saponin. Pyrene has been employed to determine the critical micellar concentration (CMC) (in the UV-vis method of determination) of saponin as a spectroscopic probe. Thus, the effectiveness of the bio-surfactant as a self-motivated adsorbent for hexavalent chromium is investigated. Several physico-chemical parameters like contact time, sorbate concentration, pH and temperature have been determined. The findings of the investigation invoked a very efficient uptake of 213.48 mg g−1 of hexavalent chromium from the contaminated water sample at a lower value of pH 2 and temperature 35°C. It is observed that the method followed a pseudo-first order kinetics, where the evaluated ΔG0 has supported the sorption as a feasible and spontaneous process. The HR-MS, FTIR, steady state Fluorescence spectroscopy, HR-TEM and UV-Vis spectroscopy have been employed for the current scientific studies.
Emission from Magnetized Accretion Disks around Young Stars
Authors: Tapia C. , Lizano S. 
Published: November 2017

Abstract
We calculate the emission of protoplanetary disks threaded by a poloidal magnetic field and irradiated by a central star. The radial structure of these disks was studied by Shu and collaborators and the vertical structure was studied by Lizano and collaborators. We consider disks around low-mass protostars (LMPs), T Tauri stars, and FU Ori stars with different mass-to-flux ratios

. We calculate the spectral energy distribution and the antenna temperature profiles at 1 and 7 mm convolved with the Atacama Large Millimeter/submillimeter Array (ALMA) and Very Large Array (VLA) beams. We find that disks with weaker magnetization (high values of

) emit more than disks with stronger magnetization (low values of

). This happens because the former are denser, hotter, and have larger aspect ratios, receiving more irradiation from the central star. The level of magnetization also affects the optical depth at millimeter wavelengths, being larger for disks with high

. In general, disks around LMP and T Tauri stars are optically thin at 7 mm, while disks around FU Ori are optically thick. A qualitative comparison of the emission of these magnetized disks, including heating by an external envelope, with the observed millimeter antenna temperature profiles of HL Tau indicates that large cm grains are required to increase the optical depth and reproduce the observed 7 mm emission at large radii.
