    Penggunaan Bahasa Mbojo di Lingkungan Masyarakat Bima di Bima: sebuah Kajian Variasi Bahasa

    Full text link
    Penelitian ini merupakan kajian variasi bahasa dengan menggunakan pendekan sosiolinguistik yang bertujuan untuk mendeskripsikan dan menjelaskan penggunaan bahasa Mbojo di lingkungan masyarakat Bima berdasarkan usia, jenis kelamin, dan kedudukan. Penelitian ini menggunakan rancangan deskriptif kualitatif. Subjek penelitian adalah masyarakat Bima penutur asli Bahasa Mbojo (dou Donggo). Data penelitian berupa percakapan yang dikumpulkan dengan metode perekaman, dan observasi, serta wawancara. Analisis data menggunakan model interaktif dengan tahap, sebagai berikut: (1) analisis data, (2) reduksi data, (3) penyajian data, dan (4) kesimpulan/verifikasi. Hasil penelitian ini menunjukkan bahwa berdasarkan usia, Pn-Mt sebaya, dan Pn tua-Mt muda menggunakan variasi lumrah dan kadang-kadang kasar; Pn muda-Mt tua, menggunaan variasi lumrah dan halus. Berdasarkan jenis kelamin, Pn–Mt L/P sebaya menggunaan variasi lumrah; Pn L-Mt P/Pn P-Mt L sebaya menggunakan variasi lumrah dan halus; Pn L tua/atasan-Mt L muda/bawahan menggunakan variasi lumrah dan kasar, sedangkan Pn-Mt P menggunakan variasi lumrah. Berdasarkan kedudukan, Pn atasan-Mt bawahan menggunakan variasi lumrah dan halus, kadang-kadang kasar; Pn-Mt yang kedudukan sama, menggunakan variasi lumrah, dan kadang-kadang halus; Pn bawahan-Mt atasan menggunakan variasi halus dan kadang-kadang lumrah. Dengan demikian, dapat disimpulkan bahwa penggunaan bahasa Mbojo di lingkungan masyarakat Bima bervariasi sesuai dengan usia, jenis kelamin, dan kedudukan/jabatan Pn-Mt- nya. Kata Kunci : penggunaan, variasi bahasa, masyarakat, bima The purposes of this study are described and explain of language user of Bima language (Bahasa Mbojo) in Bima area based on aged, gender (male and female), and status. In this research, the researcher used describes method. The subject of this study is Bima nees that use Bima language (Bahasa Mbojo). The data collections in this study are record, observation and interview. Analysis data in this study, the researcher used interactive model, like data analysis, data reduction, data display and verifying. In this study shown that Bima nees used language variety. Based on age, Bima ness used language variety, suck like Pn-Mt same age, and Pn old-Mt young they used language standard and sometime bad language; Pn young-Mt old, they used language standard and soft language. Based on gender (female and male) they used language variety suck like, Pn-Mt fame and female of the same age, they used language standard. Pn men-Mt women/Pn men-Mt women of the same age they used language standard and soft language; Pn old men-Mt young men they used language standard and bad language, while Pn-Mt women they used language standard. Whereas, based on status; Pn superior-Mt junior, they used language soft language and sometime they used language standard. In this research can conclusion that user language of Bima language (Bahasa Mbojo) in Bima area is variety based on the age, gender (male and famale) and their status

    Quantifying oil filtration effects on bearing life

    Get PDF
    Rolling-element bearing life is influenced by the number, size, and material properties of particles entering the Hertzian contact of the rolling element and raceway. In general, rolling-element bearing life increases with increasing level of oil filtration. Based upon test results, two equations are presented which allow for the adjustment of bearing L(sub 10) or catalog life based upon oil filter rating. It is recommended that where no oil filtration is used catalog life be reduced by 50 percent

    The Riccati System and a Diffusion-Type Equation

    Full text link
    We discuss a method of constructing solution of the initial value problem for duffusion-type equations in terms of solutions of certain Riccati and Ermakov-type systems. A nonautonomous Burgers-type equation is also considered.Comment: 11 pages, no figure

    Instability of spatial patterns and its ambiguous impact on species diversity

    Get PDF
    Self-arrangement of individuals into spatial patterns often accompanies and promotes species diversity in ecological systems. Here, we investigate pattern formation arising from cyclic dominance of three species, operating near a bifurcation point. In its vicinity, an Eckhaus instability occurs, leading to convectively unstable "blurred" patterns. At the bifurcation point, stochastic effects dominate and induce counterintuitive effects on diversity: Large patterns, emerging for medium values of individuals' mobility, lead to rapid species extinction, while small patterns (low mobility) promote diversity, and high mobilities render spatial structures irrelevant. We provide a quantitative analysis of these phenomena, employing a complex Ginzburg-Landau equation.Comment: 4 pages, 3 figures and supplementary information. To appear in Phys. Rev. Lett
