Implementing the New Structural Model of the Czech National Bank

The purpose of the paper is to introduce the new “g3†structural model of the Czech National Bank and illustrate how it is used for forecasting and policy analysis. As from January 2007 the model was regularly used for shadowing official forecasts, and in July 2008 it became the core model of the CNB. In the paper we highlight the most important and unusual features of the model and discuss tools and procedures that help us in forecasting and assessing the economy with the model. The paper is not meant to provide a full derivation of the model or the complete characteristics of its behavior and should not be regarded as model documentation. Rather, the paper demonstrates how the model is used and how it contributes to policy analysis.DSGE, filtering, forecasting, general equilibrium, monetary policy.

Analisa Dan Implementasi Knowledge Management System: Studi Kasus Di Sekolah Menengah Atas Negeri 1 Bayang

Found lack of good management of knowledge School SMA Negeri 1 Bayang. Knowledge management is not good can cause a lack of knowledge transmission is only delivered directly. This is because the learning activities are only delivered face to face. Knowledge is one thing that is very important for students, teachers and employees at the school, the knowledge does not have to be obtained in person or face-to-face between teachers, students and employees who share knowledge. In this study will be designed a system that can manage knowledge so well that teachers, students and employees can share knowledge and information for the actors who needs although do not follow the forum directly to the knowledge management system, when students can not attend classes can still get the material from integrated system, delivery of information by the school can also be obtained by students although unable to attend school, the teacher can not attend a workshop or meeting can get the information or the results of the workshop or meeting

Optimized adaptive enrichment designs

Based on a Bayesian decision theoretic approach, we optimize frequentist single- and adaptive two-stage trial designs for the development of targeted therapies, where in addition to an overall population, a pre-defined subgroup is investigated. In such settings, the losses and gains of decisions can be quantified by utility functions that account for the preferences of different stakeholders. In particular, we optimize expected utilities from the perspectives both of a commercial sponsor, maximizing the net present value, and also of the society, maximizing cost-adjusted expected health benefits of a new treatment for a specific population. We consider single-stage and adaptive two-stage designs with partial enrichment, where the proportion of patients recruited from the subgroup is a design parameter. For the adaptive designs, we use a dynamic programming approach to derive optimal adaptation rules. The proposed designs are compared to trials which are non-enriched (i.e. the proportion of patients in the subgroup corresponds to the prevalence in the underlying population). We show that partial enrichment designs can substantially improve the expected utilities. Furthermore, adaptive partial enrichment designs are more robust than single-stage designs and retain high expected utilities even if the expected utilities are evaluated under a different prior than the one used in the optimization. In addition, we find that trials optimized for the sponsor utility function have smaller sample sizes compared to trials optimized under the societal view and may include the overall population (with patients from the complement of the subgroup) even if there is substantial evidence that the therapy is only effective in the subgroup

Electric-field effect on coercivity distributions in FePt magneto-electric devices

International audienceWe have investigated the contribution of stochastic thermally activated processes to the electric-field effects on coercivity in FePt. Coercive field distributions were measured under different gate voltages in solid-state field-effect structures. For low voltages a shift in the coercive field distribution can be observed, however, it is not larger than the width of the distribution. Higher oltages are needed to obtain the splitting from the negative (zero) voltage distribution allowing for the unambiguous characterization of the electric-field effect. A virtual unipolarity in the electric-field effect has been identified as a feature introduced by the dielectric layer that disappears upon annealing

HAK ANAK PASCA PERCERAIAN (Studi Kasus diNagari Pakan Rabaa Timur Kec. Koto Parik Gadang Diateh Kabupaten Solok Selatan)

Artikel esis ini mengangkat fenomena tentang banyaknya anak-anak yang tidak mendapatkan hak nafkah dari ayah lagi pasca perceraian, sehingga anak-anak tersebut menjadi korban imbasnya perceraian orang tua. Ada sebagian anak yang terlantar, putus sekolah karena kurang biaya, terpaksa menjadi kuli untuk mencari uang kebutuhannya sendiri akibat ibunya miskin, belum lagi masalah psikologis lainnya. Penelitian ini merupakan jenis penelitian kualitatif yang menggunakan metode triangulasi dalam pengambilan data yaitu: wawancara, dokumentasi dan studi pustaka.     Berdasarkan hasil penelitianyang telah didapatkan, bahwa tidak terpenuhinya hak nafkah anak pasca perceraian disebabkan karena kelalaian ayah itu sendiri, baik karena ketidaktahuan tentang hukum maupun karena kesengaja melepaskan tanggung jawab. Walaupun ada sebagian pendapat yang mengaitkan tidak terpenuhinya nafkah tersebut karena pengaruh adat matrilinier yang dipegangnya.  Memang didalam hukum adat minang seorang mamak pusako mempunnyai hak wewenang tertinggi bagi kemenakannya termasuk dalam pemenuhan nafkah kemanakan, posisi ini berada diatas wewenang ayah kandung anak itu sendiri, namun karena pergeseran waktu dan semakin menipisnya harta pusaka tinggi serta asimilasi agama Islam yang kuat, adat tersebut sudah bergeser sehingga wewenang ayah menempati posisi yang tinggi terhadap anak, bukan mamak lagi, termasuk hak nafkah anak, mamak pada masa ini hanya sebagai simbol saja dan hanya mengurus masalah-masalah upacara-upacara adat.Kemudian didalamUndang-undang Republik indonesia juga sudah diatur tentang perlindungan hak anak, disana ditegaskan tentang sanksi dan denda bagi Ayah yang mangkir terhadap tugasnya. Namun sayangnya dalam beberapa kasus ini tidak ada satupun yang menuntut hak nafkah  anak-anak mereka ke pihak hukum, disebabkan karena masyarakat masih awam terhadap hukum ataupun karena sikap toleransinya yang tinggi. Sehingga akibat keabaian tersebut kasus-kasus seperti ini tetap marak terjadi. Pihak pemerintah nagari pun belum pernah menyelesaikan kasus seperti ini, karena pemerintah nagari bersifat menunggu laporan/pengaduan warga. Sehingga Solusi yang bisa kita tawarkan disini, dibutuhkan pencerdasan hukum ketengah-tengah masyarakat, baik hukum syari’at agama maupun hukum undang-undang negara tentang kewajiban ayah untuk tetap memenuhi hak nafkah anak pasca perceraian serta mendorong keberanian bagi korban untuk menuntut kepihak hukum ketika kasus tersebut terjadi. Kemudian perlu adanya peraturan pemerintah nagari untuk menangani kasus ini, agar terjamin hak-hak anak pasca perceraian seperti pembuatan PERNA (peraturan nagari) dan PERDA (peraturan daerah)yang mana aturan didalamnya menjamin dan melindungi hak-hak anak pasca perceraian
