Cumulative Prospect Theory portfolio selection

We introduce elements of Cumulative Prospect Theory into the portfolio selection problem and then compare stock portfolios selected under the behavioral approach with those selected according to classical approaches, such as Mean Variance and Mean Absolute Deviation ones. The mathematical programming problem associated to the behavioral portfolio selection is highly non-linear and non-differentiable; for these reasons it is solved using a Particle Swarm Optimization approach. An application to the STOXX Europe 600 equity market is performed.We introduce elements of Cumulative Prospect Theory into the portfolio selection problem and then compare stock portfolios selected under the behavioral approach with those selected according to classical approaches, such as Mean-Variance and Mean Absolute Deviation ones.

Certains aspects de la conception hydraulique des aqueducs romains

The Roman aqueducts were large water supply systems delivering water for public health usage. However little is known on the hydraulic design of the aqueducts. The Roman engineers, contemporary of Hero of Alexandria, had a strong expertise and experience in hydraulic engineering. Several regulations basins were found along the aqueducts. It is proposed that the operation was based upon a dynamic regulation principle. Associated issues are discussed. Two types of major hydraulic structures were also built : dropshaft cascades and culverts. The hydraulic engineers who designed these structures have a sound knowledge and understanding of basic hydraulics. Who were they? Although we do not know, the writer is impressed by their technical expertise. They knew more than modern hydraulic engineers

REVITALISASI KEMAMPUAN MEMBACA BAGI GURU BAHASA PRANCIS SEKOLAH MENENGAH KEJURUAN

Abstrak: Guru bahasa Prancis di Sekolah Menengah Kejuruan merupakan ujung tombak dalam memperkenalkan bahasa Prancis kepada siswa Sekolah Menengah Atas. Melalui merekalah, para siswa mengenal bahasa Prancis. Oleh karena itu, guru bahasa Prancis sebagai sumber belajar siswa seyogyanya memiliki sertifikat kompetensi bahasa Prancis tingkat DELF B2. Salah satu kemampuan kebahasaan yang diujikan adalah kemampuan membaca. Agar guru-guru yang mengikuti ujian DELF B2 memiliki strategi dalam mengerjakan ujian, diperlukan pelatihan. Pelatihan yang dilakukan untuk guru-guru tersebut berupa latihan mengerjakan soal-soal kemampuan Membaca pada ujian DELF dengan menggunakan metode interaktif. Pelatihan berlangsung selama 4 kali pertemuan à 5 jam. Evaluasi diberikan sebanyak dua kali. Evaluasi kedua menghasilkan 2 peserta memperoleh nilai A, 6 peserta memperoleh nilai B dan 6 peserta bernilai C. Hasil perhitungan menunjukkan bahwa kemampuan memahami teks mereka meningkat setelah diberikan pelatihan.Abstract:  French teachers in vocational schools are the spearhead in introducing French to high school students. Through them, students learn French. Therefore, French teachers as a source of student learning should have a certificate of French competence at the DELF B2 level. One of the language skills tested is reading comprehension. For teachers who take the DELF B2 exam to have a strategy for taking the exam, training is needed. Training conducted for these teachers is in the form of exercises to work on reading questions on the DELF exam using interactive methods. The training lasts for 4 meetings à 5 hours. Evaluation is given twice. The second evaluation resulted in 2 participants getting an A, 6 participants getting a B and 6 participants having a C. The calculation results showed that the ability to understand the texts improved after being given training
