The Asymptotic Cone of Teichm\"uller Space: Thickness and Divergence
We study the Asymptotic Cone of Teichm\"uller space equipped with the
Weil-Petersson metric. In particular, we provide a characterization of the
canonical finest pieces in the tree-graded structure of the asymptotic cone of
Teichm\"uller space along the same lines as a similar characterization for
right angled Artin groups by Behrstock-Charney and for mapping class groups by
Behrstock-Kleiner-Minksy-Mosher. As a corollary of the characterization, we
complete the thickness classification of Teichm\"uller spaces for all surfaces
of finite type, thereby answering questions of Behrstock-Drutu,
Behrstock-Drutu-Mosher, and Brock-Masur. In particular, we prove that
Teichm\"uller space of the genus two surface with one boundary component (or
puncture) can be uniquely characterized in the following two senses: it is
thick of order two, and it has superquadratic yet at most cubic divergence. In
addition, we characterize strongly contracting quasi-geodesics in Teichm\"uller
space, generalizing results of Brock-Masur-Minsky. As a tool, we develop a
complex of separating multicurves, which may be of independent interest.Comment: This paper comprises the main portion of the author's doctoral

Relationship between education, health and crime: fable, fallacy or fact
The study is an empirical evaluation of specific criminal activities. The relationship of criminal activities with inflation, unemployment, investment, education and health are examined through an annual data set from 1980 to 2007. To test the order of integration, Augmented Dickey Fuller test and Philips Perron are used. To find the evidences of long run relationship, Cointegrating Regression Durban Watson, Engle Granger two step procedure and Johansen and Juselis method is used. Results show that education and health have a positive and significant relationship with most of the criminal activities in the study. Another unusual finding is that inflation and unemployment are insignificant in case of two out of three crimes, however, investment is found highly significant and negatively related with these crimes. The study indicates that an educated, healthy and legally employed person can also be involved in unsophisticated blue collar criminal activities.Education; health; Crime

The purpose of this study is to describe the implementation of gadget application in learning English vocabulary. The subject was the student at six semesters of Department of English Education, Faculty of Tarbiyah and Teachers training, State Islamic University of North Sumatera in academic year 2017/2018.
They were key informant and supporting informants. Key informant is one of the students in eight semesters of Department of English Education at State Islamic University of North Sumatera Medan. The supporting informants are lecturer, parents, and friends from the students.
It was descriptive qualitative research design of which instrument are observation, interview, and documentation. The research administered observation to the key informant. A retrospective interview was conducted to the key informant and supporting informant. The data analyzis using reduction, display, and verification from Mile and Huberman.
The results of the data analysis showed there are seven findings of the implementation of gadget application in learning English vocabulary: (1) Gadget in Hand, (2) Gadget Focusing, (3) Getting New Information or Words, (4) Combination of Learning, (5) Communicating, (6) Entertaining, (7) Reason Using Gadget
MENINGKATKAN HASIL BELAJAR BAHASA INDONESIA PADA SISWA KELAS VI SD NEGERI 18 KENDARI MELALUI PEMBELAJARAN KOOPERATIF TYPE STAD
Abstrak: Tujuan penelitian ini adalah: 1) untuk mengetahui Aktivitas guru dalam Pembelajaran Bahasa Indonesia dengan diterapkannya metode pembelajaran kooperatif model STAD pada siswa Kelas VI SDN 18 Kendari; 2) untuk mengetahui aktivitas siswa dalam pembelajaran Bahasa Indonesia dengan diterapkannya metode pembelajaran kooperatif model STAD siswa kelas VI SDN 18 Kendari; dan 3) untuk mengetahui hasil belajar Bahasa Indonesia yang diajar dengan metode pembelajaran kooperatif model STAD pada siswa kelas VI SDN.18 Kendari. Temuan pada pelaksanaan tindakan pada siklus I,aktivitas siswa dengan menggunakan pembelajaran Kooperatif Model STAD dalam pembelajaran Bahasa Indonesia pertemuan I berada pada skor 53,93 atau kategori cukup dan pertemuan II diperoleh 64,48 atau kategori cukup dan rata-rata keseluruhan diperoleh 59,21 atau kategori cukup. Hasil belajar siswa pada siklus II diperoleh nilai rata-rata prestasi belajar siswa adalah 70,29 dan ketuntasan belajar mencapai 94,11% atau ada 32 siswa dari 34 siswa sudah tuntas belajar.Hasil tersebut menunjukkan bahwa pada siklus pertama secara klasikal Siswa tuntas belajar,karena siswa yang memperoleh nilai >70 hanya sebesar 94,11% hasil tersebut ketuntasan belajar telah tercapai karena yang mendapat nilai >70 lebih besar dari persentase ketuntasan yang dikehendaki.Hal ini disebabkan karena siswa sudah berulang guru menggunakan pembelajaran dengan menggunakan pembelajaran kooperatif model STADBerdasarkan hal tersebut maka dapat dikatakan bahwa model pembelajaran kooperatif model STAD dapat memberikan dampak yang sangat baik terhadap aktivitas guru,siswa dan hasil belajar Bahasa Indonesia siswa pada Kelas VI SDN.18 Kendari. Kata Kunci : Pembelajaran, Kooperatif, Type Sta
RESPON MASYARAKAT KAMPUS KEAGAMAAN TERHADAP NARASI HOAKS: TELAAH ANTROPOLINGUISTIK
Penelitian ini bertujuan mengklasifikasikan respon masyarakat di lingkungan kampus keagamaan terhadap narasi hoaks, dan menjelaskan potensi ancaman narsi hoaks terhadap pola keberagamaan dan keberagaman serta menjelaskan perspektif antropolinguistik terhadap narasi hoaks di lingkungan lembaga keagamaan kampus,. Metode yang digunakan dalam penelitian ini adalah metode kualitatif. Hasil dari penelitian ini: (1) Respon masyarakat di lingkungan kampus keagamaan terhadap narasi hoaks bahwa kecendrungan mereka tidak terlalu menanggapi berita hoaks terutama yang tersebar di media sosial. Hal ini menunjukkan kalangan masyarakat kampus memiliki kemampuan “memfilter” berita. Kebiasaan melakukan klarifikasi dan verifikasi merupakan hal yang positif yang menunjukkan bahwa kalangan masyarakt kampus memiliki tingkat literasi yang cukup tinggi sehingga penyebaran berita hoaks tidak serta merta menciptakan kegelisahan apalagi perdebatan yang menjurus pada konflik. (2) Potensi ancaman narasi hoaks terhadap pola keberagamaan dan keberagaman di kalangan masyarakat kampus mengindikasikan tidak begitu besar terhadap masyarakat kampus dikarenakan tingkat literasi kalangan masyarakat kampus yang cukup tinggi. (3) Antropolinguistik melihat bahwa narasi hoaks dapat menggeser dan munculkan nilai, norma dan budaya dalam lingkungan masyarakat karena bahasa memiliki hubungan yang erat dengan budaya, begitu juga budaya dapat berisikan nilai-nilai dan norma dalam kehidupan masyarakat pada sebuah bangsa dan negara
Teacher\u27s Domination in Classroom Interactions: a Critical Analysis for Developing a Qualified Teacher-Students Relationship
This study was designed to describe the form of teacher\u27s domination in classroom interactions and explainlanguage features which represent it. This qualitative study employed the critical discourse analysis model by Fairclough. Data was obtained from the speech produced by six secondary school teachers in Luwu Timur Regency, South Sulawesi. The data was collected through recording, field-notes, and interviews. The data was analyzed using Miles and Huberman flow model which covers: (1) condensation, (2) data presentation, (3) temporary data deduction and verification, and (4) final conclusion making. The results of the study revealed that; (1) teachers controlled the classroom interactions by labelling students, threatening, making fun of students, underestimating, getting angry with them, giving punishment, expressing dissatisfaction/ disappointment, and emphasizing their authority; (2) language features which reflect teachers\u27 domination tnthe teacher-students communication include: (a) the use of vocabulary, namely marginal vocabulary,metaphors, personal pronouns, and evaluative vocabulary; and (b) the use of grammars, of which aredeclarative sentences, imperative sentences, interrogative sentences, negative sentences, and modality. The research findings suggest teachers to develop qualified teacher-students interactions by avoiding the use of language features which imply teacher\u27s domination
