    The sea cucumber fishery in waters off Maine is developing and has recently experienced great increases in landings, corresponding to expanding export markets. Between 1994 and 1996, reported landings ranged from one to three million pounds (Fig. 1). In 1999, reported landings were over eight million pounds and rose to over nine million in 2000 (Feindel1). Like other developing fisheries, we have little information about the biology and ecology of the sea cucumber off Maine, limited data on the fishery, and little knowledge about the key life history processes that characterize its population dynamics. Therefore, we have a limited understanding of the current status of the resource and the impacts the fishery may have on the stock

    PERTANGGUNGJAWABAN PIDANA TERHADAP ABORTUS PROVOCATUS CRIMINALIS MENURUT PASAL 347 KUHP

    Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana pertanggungjawaban tindakan aborsi ditinjau dari penerapan hukum pidana yang berlaku dan bagaimana penanggulangan tindak pidana abortus provocatus criminalis. Dengan menggunakan metode penelitian yuridis normatif, disimpulkan: 1. Tindak pidana aborsi terjadi akibat kehamilan yang terjadi diluar nikah dan kurangnya pemahaman kepada masyarakat dalam memberikan sosialisasi mengenai hubungan diluar nikah serta pengawasan penegak hukum dalam melakukan pencegahan di setiap penginapan dan tempat praktik dokter, hal ini berpeluang terjadi apabila kurangnya pengawasan dari pihak-pihak terkait dalam setiap lembaga yang diberikan kewenangan oleh Undang-Undang dalam memberikan izin serta pengawasan dalam membentuk masyarakat yang sadar akan dampak buruk atau resiko dalam hubungan sex diluar nikah, dan sanksi tehadap lembaga yang kurang maksimal dalam melakukan tugas pengawasan dalam setiap laporan yang diperoleh baik dari masyarakat atau media masa. Penulis juga mengimbau tehadap seluruh pembaca akan pertanggungjawaban hukum terhadap perbuatan yang tentunya melanggar Undang-Undang baik yang membantu melakukan aborsi, dan yang dibantu untuk melakukan aborsi, tentunya dapat dikenakan sanksi pidana bagi pihak yang membantu dan membantu dan sanksi administrasi terhadap ijin praktik dokter.  2. Telah diaturnya abortus sebagai tindak pidana terlihat dari pengaturan KUHP Bab XIX mengenai kejahatan terhadap nyawa dan Undang-Undang Nomor 36 Tahun 2009 tentang Kesehatan dengan ancaman pidana di dalamnya menunjukkan upaya penanggulangan tindak pidana abortus provocatus criminalis yang dilakukan Pemerintah Indonesia cukup serius. Dengan melarang dan menganggap illegal semua praktik abortus yang tidak dengan indikasi medis, hal itu dianggap langkah terbaik oleh Pemerintah untuk melindungi ibu hamil beserta janinnya dan untuk menekan angka abortus. Upaya pencegahan terhadap tindakan abortus provocatus criminalis, di luar ranah hukum sering dilakukan, terutama yang bersifat preventif di lingkungan pergaulan sosial, yang menekankan pada pendekatan sosialisasi akan bahayanya aborsi.Kata kunci: Pertanggungjawaban Pidana, Abortus Provocatus Criminalis.

    Exact and Approximate Relaxation Techniques for Computational Guidance

    Get PDF
    The focus of this dissertation is in the development and application of relaxation techniques that enable efficient and real-time solution of complex computational guidance problems. Relaxations transform a non-convex constraint into a convex constraint and provides proof that the optimal solutions to the relaxed problem are optimal for the original problem. Unique contributions of this work include: 1) a relaxation technique for solving fixed final time problems between fixed points, 2) a performance analysis on the application of computational guidance for the Mars Ascent Vehicle, and 3) establishment of sufficient conditions for non-singularity of optimal control for problems on a smooth manifold with mixed constraints. The first result states that for annularly constrained linear systems, controllability is a sufficient condition for the problem to be solvable as a sequence of convex programs. The second result applies relaxations to an ascent problem. The third result is the most general result to date for problems with mixed constraints. It uses a minimum principle on manifolds with mixed constraints to analyze the problem in a geometric framework, and shows that strong observability of the dual system is sufficient for non-singularity

    Descriptions of Differentiated Instruction in Mathematics in a Title 1 School District

    Get PDF
    In an urban Title 1 school district, the average number of Grade 3-5 students who scored proficient or advanced on the state standardized assessment was 37.3% below Grade 3-5 students countywide and 19.4% below Grade 3-5 students statewide. Low mathematics scores may indicate a gap in practice that affects student achievement. The purpose of this descriptive case study was to examine teachers\u27 descriptions of instructional strategies implemented to mediate instruction for students who struggle in mathematics. This study was based on the conceptual framework of Tomlinson\u27s differentiated instruction (DI), a means of accommodating the varied ways that students learn. The research questions guided an inquiry into how teachers of students in Grades 3-5 in the school district described DI in practice and explained their professional development on DI strategies. Data were collected from individual interviews with 8 elementary school teachers of students in Grades 3-5 and an instructional coach in the local school district with 3 or more years of experience who considered themselves knowledgeable of DI. I coded the meaningful data collected from the interviews and subsequently formed themes. Themes that emerged from the interviews included defining DI, tools for instruction, classroom set-up and transitioning, assessments, professional development, and grouping strategies. Results revealed that interviewees were confident in defining and facilitating DI grouping strategies for English and language arts but felt the need for more professional development to implement and understand DI in relation to mathematics. The study outcome may impact social change by affecting the gap in practice through professional development that helps teachers implement DI strategies in the classroom to improve student achievement in mathematics

    Inferring Concept Prerequisite Relations from Online Educational Resources

    Full text link
    The Internet has rich and rapidly increasing sources of high quality educational content. Inferring prerequisite relations between educational concepts is required for modern large-scale online educational technology applications such as personalized recommendations and automatic curriculum creation. We present PREREQ, a new supervised learning method for inferring concept prerequisite relations. PREREQ is designed using latent representations of concepts obtained from the Pairwise Latent Dirichlet Allocation model, and a neural network based on the Siamese network architecture. PREREQ can learn unknown concept prerequisites from course prerequisites and labeled concept prerequisite data. It outperforms state-of-the-art approaches on benchmark datasets and can effectively learn from very less training data. PREREQ can also use unlabeled video playlists, a steadily growing source of training data, to learn concept prerequisites, thus obviating the need for manual annotation of course prerequisites.Comment: Accepted at the AAAI Conference on Innovative Applications of Artificial Intelligence (IAAI-19

    A Novel HPLC Method for Determination of Phenytoin in Human Plasma

    Get PDF
    Aim: Aim of this research was to develop and validate a simple, efficient and reproducible high performance liquid chromatography method to measure phenytoin concentrations in human plasma Study Design: Linearity, selectivity, sensitivity, accuracy and precision of the analytical methods were validated according to ICH guidelines. Methodology: The method employed a Phenomenex C18 column kept at 25ºC. The mobile phase consisted of a 0.05 M potassium dihydrogen phosphate buffer solution (pH 2.8) and methanol in a ratio of 60:40, respectively. The flow rate of the mobile phase was 0.7 mL/min. Phenytoin was detected at a wavelength of 250 nm. Results: Phenytoin was eluted at 7.4 minutes with no interference with the other components of the human plasma. The method was linear in the range of 1-25 μg/mL (R2 = 0.9998). The LOD and LOQ were calculated as 0.07 μg/mL and 0.20μg/mL, respectively. Recovery, tested in the range of 5-20 μg/mL, was found to be 99.21 - 102.09%. Intraday and interday precision RSDs were 0.65 and 0.29%, respectively. Conclusion: The proposed method is fast, reliable and reproducible, and can be recommended to measure free phenytoin levels in the blood
