Dust properties from GALEX observations of a UV halo around Spica

GALEX has detected ultraviolet halos extending as far as 5$^{\circ}$ around four bright stars (Murthy et al. (2011)). These halos are produced by scattering of starlight by dust grains in thin foreground clouds that are not physically associated with the star. Assuming a simple model consisting of a single layer of dust in front of the star, Murthy et al.(2011) have been able to model these halo intensities and constrain the value of the phase function asymmetry factor $g$ of the scattering grains in the FUV and NUV. However due to the uncertainty in the dust geometry they could not constrain the albedo. In this work we have tried to constrain the optical constants and dust geometry by modeling the UV halo of Spica. Since the halo emission is not symmetric, we have modeled the Northern and Southern parts of the halo separately. To the North of Spica, the best-fit albedo is 0.26$\pm$0.1 and $g$ is 0.58$\pm$0.11 in the FUV at the 90% confidence level. The corresponding limits on the distance and optical depth ($\tau$) of the dust sheet is 3.65$\pm$1.05 pc and 0.047$\pm$0.006 respectively. However, owing to a complicated dust distribution to the South of Spica, we were unable to uniquely constrain the dust parameters in that region. Nevertheless, by assuming the optical constants of the Northern region and assuming a denser medium, we were able to constrain the distance of the dust to 9.5$\pm$1.5 pc and the corresponding $\tau$ to 0.04$\pm$0.01.Comment: 4 pages, accepted for publication in Earth, Planets and Spac

Workplace bullying-A case study on RHB Bank Berhad, Malaysia

This study aimed to determine if workplace bullying occurs at RHB Bank Berhad. In addition, this study also analyzed if there was a significant relationship between workplace bullying and the respondents’ demographic information such as age, gender, race, years of employment and position. Types of bullying are divided into six forms, namely work-related bullying, personal attacks, social isolation, verbal aggression, physical aggression and the spreading of rumours. A total of 100 questionnaires were selected by random cluster sampling of the group and distributed, whereby 76 employees of RHB Bank branches at Pantai Lebuh and Jelutong, Penang and Bakar Arang , Sungai Petani responded. The instrument used in this study was the slightly modified set of questionnaires NAQ (Negative Acts Questionnaire) accordingly. The data obtained were processed collectively using the Statistical Package for Social Sciences (SPSS) version 19. Statistical techniques used were frequency, percentage, mean, median, standard deviation, Hypothesis Testing and Pearson’s Correlation. Based on the analysis of the questionnaires, it was shown that there exists a significant relationship between gender, job designation and duration of employment with workplace bullying. Race and age, however, did not seem to have a significant relationship with workplace bullyin

Implikatur Slogan Iklan Produk Makanan dan Minuman di Televisi

Bahasa iklan sering kali bermakna ganda. Hal tersebut disengaja oleh pembuat iklan untuk memengaruhi calon pembeli secara persuasif. Banyak calon pembeli yang dalam hal ini adalah penonton tayangan iklan di televisi tidak menyadari cara berbahasa pembuat iklan. Salah satu aspek bahasa iklan yang persuasif adalah slogan yang berupa bahasa verbal. Slogan tersebut berupa kalimat pendek yang ringkas, jelas, dan menarik sehingga dapat memikat calon pembeli. Slogan tersebut merupakan implikatur yang digunakan oleh pembuat iklan untuk menarik rasa simpati penonton. Tujuan penelitian ini adalah agar masyarakat dapat memahami dengan baik implikatur dalam slogan iklan produk makanan dan minuman sehingga mereka cermat sebelum memutuskan untuk membeli atau tidak membelinya. Penelitian ini dilaksanakan dengan menggunakan metode simak untuk menjaring data. Sementara itu, metode padan pragmatik digunakan untuk menganalisis data penelitian yang berupa slogan iklan yang berbahasa Indonesia. Adapun hasil penelitian ini adalah ditemukannya jenis-jenis implikatur slogan iklan produk makanan dan minuman. Jenis-jenis implikatur yang terdapat dalam tayangan iklan makanan dan minuman tersebut antara lain implikatur deskripsi produk, implikatur kualitas, implikatur manfaat, dan implikatur kasiat

Examining Multiple Imputation for Measurement Error Correction in Count Data with Excess Zeros

Measurement error and missing data are two common problems in wildlife population surveys. These data are collected from the environment and may be missing or measured with error when the observer’s ability to see the animal is obscured. Methods such as video transects for estimating red snapper abundance and aerial surveys for estimating moose population sizes are highly affected by these problems since total abundance will be underestimated if missing/mismeasured counts are ignored. We shall refer to this problem as visibility bias; it occurs when the true counts are observed when visibility is high, partially observed when visibility is low (mismeasured), and unobservable when visibility is lost (missing). In addition, data from animal population surveys are often sparse since not all sampled regions are inhabited by the species. In this dissertation, we examine several multiple imputation techniques which can be used to correct measurement error in sparse count data that are subject to visibility bias. We present several off-the-shelf imputation models and our developed imputation model HBZIP as well as a modified hot deck imputation approach. We evaluate their performance for estimating total abundance and habitat occupancy rate and assess the robustness of the HBZIP model against visibility model misspecification. We further incorporate Bayesian model averaging approach into the HBZIP model to mitigate the impact of visibility model uncertainty and illustrate its application on real data collected from moose population surveys

Kesantunan Berbahasa pada Judul Berita Politik di Media Massa Online

Judul berita politik di media massa online sering ditulis dengan memanfaatkan daya ilokusi kuat dengan memperhatikan pula aspek kesantunan. Dengan demikian, setiap judul berita politik mengandung unsur-unsur kesantunan yang beragam. Kesantunan berbahasa dalam judul berita menunjukkan adanya strategi penyampaian pesan oleh penulis beritaTujuan utama penulis dengan memanfaatkan ilokusionari force adalah untuk menarik minat pembaca sebanyak-banyaknya demi komersialisme dalam industri persuratkabaran. Penelitian ini dilaksanakan secara kualitatif dengan menggunakan data berupa judul-judul berita politik di media massa online. Data dikumpulkan dengan metode simak dan teknik bebas libat cakap. Peneliti mengobservasi keberagaman data di berbagai portal berita online. Selanjutnya, judul-judul berita tersebut dicatat untuk dijadikan data penelitian. Proses selanjutnya adalah analisis data yang menggunakan metode padan pragmatik. Data dikelompokkan berdasarkan kategori-kategori kesantunan. Hasil penelitian ini adalah adanya pematuhan terhadap maksim-maksim kesantunan Leech, seperti kebijaksanaan, penerimaan, kemudahan, kerendahan hati, kecocokan, dan kesimpatian. Hasil analisis juga menunjukkan adanya pelanggaran terhadap maksim-maksim tersebut dengan tujuan yang sama dari alasan pematuhan terhadap maksim-maksim dalam prinsip kesantunan, yaitu menarik minat pembaca sebanyak-banyaknya

KESALAHAN BERBAHASA DALAM SKRIPSI MAHASISWA PRODI PENDIDIKAN BAHASA DAN SASTRA INDONESIA UNIVERSITAS TIDAR

Students of the Indonesian Language and Literature Education Study Program (PBSI) should master scientific writing in Indonesian. However, the facts on the ground are different. There are many language errors found in student theses. This study aims to describe the language errors of PBSI students in their thesis. By knowing the types of students' language errors in their thesis, Indonesian language learning, especially writing skills, can be improved in the future. Therefore, this research is beneficial for students, teachers, and lecturers. This research was conducted qualitatively with data sources obtained through population and sampling techniques. The data source is the student's thesis of PBSI, so the data is in the form of written language. Meanwhile, the research data analysis used the agih method with the lesap technique, the ganti technique, and the ubah wujud technique. The results of this study are the existence of language errors at various linguistic levels, namely phonology, morphology, and syntax. Language errors at the morphological level are in the form of errors in the use of punctuation marks. Errors at the morphological level are in the form of errors in the affixation process. Meanwhile, errors at the syntactic level are in the form of errors in the sentence composing process
