Adiabatic quantum pumping through surface states in 3D topological insulators
No full textWe investigate adiabatic quantum pumping of ballistic Dirac fermions on the surface of a strong three-dimensional topological insulator. Two different geometries are studied in detail, a normal metal–ferromagnetic–normal metal (NFN) junction and a ferromagnetic–normal metal–ferromagnetic (FNF) junction. Using a scattering matrix approach, we show that each time a new resonant mode appears in the transport window the pumped current exhibits a maximum and provide a detailed analysis of the position of these maxima. We also predict a characteristic difference between the pumped current in NFN- and FNF-junctions: whereas the former vanishes for carriers at normal incidence, the latter is finite due to the different nature of wavefunction interference in the junctions. Finally, we predict an experimentally distinguishable difference between the pumped current and the conductance.Quantum NanoscienceApplied Science

Alternatif Konsep Kelembagaan untuk Penajaman Operasionalisasi dalam Penelitian Sosiologi
Full text linkEnglishThe experts have no the same perception regarding the term of “institution”. This leads to unworkable definitions and concepts. This paper reviews the existing thoughts, especially those related with the term of “organization”, and simplifies them to formulate an easier concept which enables scientists and practitioners to work with. Different meanings exist due to different points of views of the experts, especially in early stage of sociology development. Sine 1950’s, social institution and social organization have been distinguished strictly. The author proposes a solution, i.e., the term of “institution” to mention the social system in which it is classified into two important components, namely “institutional aspect” and “organizational aspect”. Through this differentiation, it is expected that the analysis becomes more detailed, signifies the strong and weak aspects, and enables to choose the strategy of developing it.IndonesianIstilah “kelembagaan” belum memperoleh kesamaan pengertian di kalangan para ahli. Hal ini menyebabkan munculnya beberapa pengertian dan konsep yang menyebabkan tidak dapat dioperasionalkan. Tulisan ini berusaha melakukan tinjauan (review) seluruh pemikiran yang berkembang, terutama kaitannya dengan istilah “organisasi”, untuk kemudian merumuskan satu konsep yang lebih mudah sehingga dapat dipergunakan baik untuk kalangan ilmuwan maupun praktisi. Ketidaksamaan pemaknaan terjadi karena setiap ahli memiliki titik pandang yang berbeda dalam membahasnya, terutama pda masa-masa awal perkembangan sosiologi. Namun, semenjak era 1950-an, sesungguhnya sudah terlihat adanya pembedaan yang tegas antara kelembagaan (social institution) dan organisasi (social organization). Sebagai solusinya, penulis menggunakan istilah “kelembagaan” untuk menyebut suatu sistem sosial dimaksud, yang didalamnya dapat dibagi menjadi dua komponen penting, yaitu “aspek kelembagaan” dan “aspek keorganisasian”. Dengan membedakan seperti ini, maka analisa dapat lebih mendalam, dapat diketahui aspek apa yang kuat dan lemah, serta dapat memilih strategi untuk pengembangannya
TANTANGAN PENGINTEGRASIAN JAMINAN KESEHATAN DAERAH KE DALAM JAMINAN KESEHATAN NASIONAL UNTUK MEWUJUDKAN CAKUPAN PELAYANAN KESEHATAN UNIVERSAL
Full text linkThis study is to review the facts in the health care field, where WHO has agreed to achieve Universal Health Coverage (UHC) in 2014. UHC is a health system that ensures every citizen in the population has fair access to a qualified promotive, preventive, curative, and rehabilitative health care at reasonable costs. Universal coverage contains two core elements namely equitable access to qualified health services for every citizen, and the protection of financial risks when people use health services. Indonesia is currently in transition towards UHC. Law No. 40 Year 2004 about National Social Security System (UU SJSN)' has answered the basic principles of UHC by requiring every citizen to have access to comprehensive health services that are needed through pre-effort system. Then, the author will formulate solutions to these problems which can be seen as a recommendation for the implementation of health care development. Problem solving methods used in formulating solutions to problems are policy analysis using William Dunn and Abidin's theory, and the Fishbone Diagram. Based on the analysis, the author advises the need to arrange a formulation that meets the demands of integration of Jamkesda into JKN. Formulation of policies which have been directed towards the centralization of health financing through JKN program must be balanced by providing a flexible space for local governments to participate in decision making processes dynamically. This formulation is called Centralized Dynamic Integration policy formulation.Â
