<p class="Normal1">News has been spread internationally since it was digitalized. This situation makes machine translation used as a tool to solve the language barrier problem, as it is cheap and fast compared to human translators. However, the translation by Machine Translation is not always correct. In fact, it results in more problems than in successful translation; in other words, the use of this machine is like ‘garbage in, garbage out’. However, not many studies have been conducted to provide evidence of the weaknesses of machine translation. This research paper attempts to discover the translation methods and procedures of the “translate to Indonesian” featured by Google Translate in the translation of CNN International current news from English to Indonesian. The data consist of 10 pieces of entertainment news that are published online on CNN International News. A descriptive-qualitative approach is used to analyze the data. The scope of the analysis is lexical words only. The translated news was observed and compared to the original news in order to identify the methods and procedures applied in the translation results by the Machine Translation. The results of this analysis reveal that the “translate to Indonesian” feature from Google Translate commonly uses the literal and faithful translation methods and the procedure mostly found is borrowing. Consequently, the translation by this machine is still awkward and requires substantial improvement.</p>

Crowdion defects are produced in body-centered-cubic metals under irradiation. Their structure and diffusive dynamics play a governing role in microstructural evolution, and hence the mechanical properties of nuclear materials. In this paper, we apply the analytical Frenkel-Kontorova model to crowdions and clusters thereof (prismatic dislocation loops) and show that the Peierls potential in which these defects diffuse is remarkably small (in the micro eV range as compared to the eV range for other defects). We also develop a coarse-grained statistical methodology for simulating these fast-diffusing objects in the context of object kinetic Monte Carlo, which is less vulnerable to the low barrier problem than naïve stochastic simulation.

This paper is concerned with modelling the dynamics of social outbursts of activity, such as protests or riots. In this sequel to our work in Berestycki et al. (Networks and Heterogeneous Media, vol. 10, no. 3, 1–34), written in collaboration with J-P. Nadal, we model the effect of restriction of information and explore its impact on the existence of upheaval waves. The system involves the coupling of an explicit variable representing the intensity of rioting activity and an underlying (implicit) field of social tension. We prove the existence of global solutions to the Cauchy problem in ${\mathbb R}^d$ as well as the existence of traveling wave solutions in certain parameter regimes. We furthermore explore the effects of heterogeneities in the environment with the help of numerical simulations, which lead to pulsating waves in certain cases. We analyse the effects of periodic domains as well as the barrier problem with the help of numerical simulations. The barrier problem refers to the potential blockage of a wavefront due to a spatial heterogeneity in the system which leads to an area of low excitability (referred to as the barrier). We conclude with a variety of open problems.

With the popularity of the network and mobile Internet, numerous social network platforms appeared in the world. Also, there have been a large number of users using a plurality of social network platforms at the same time. When these users use multiple social network platforms, they need to overcome many difficulties such as switching social network client applications frequently and so on. This article takes consideration of the needs of the multiple social networks’ users, proposing a solution to solve multi-barrier problem, and demonstrating the feasibility and effectiveness of the method by actual cases.

We consider the problem of pricing step double barrier options with binomial lattice methods. We introduce an algorithm, based on interpolation techniques, that is robust and efficient, that treats the "near barrier" problem for double barrier options and permits the valuation of step double barrier options with American features. We provide a complete convergence analysis of the proposed lattice algorithm in the European case.

Klaim persalinan yang rendah mengindikasikan ketidakpuasan bidan pada implementasi kebijakan jaminan persalinan (Jampersal) di Kabupaten Purbalingga. Penelitian ini bertujuan mengeksplorasi penyebabkan ketidakpuasan bidan dan hambatan implementasi kebijakan Jampersal di tingkat pelaksana. Penelitian deskriptif dengan desain studi kasus ini melakukan pengumpulan data kualitatif pada periode Maret _ Juli 2012 terhadap informan empat bidan pegawai negeri sipil (PNS) dan empat bidan pegawai tidak tetap (PTT). Ditemukan ketidakpuasan bidan dan hambatan pelaksanaan kebijakan Jampersal tahun 2012, meliputi; besaran, pemotongan, dan lama klaim persalinan, penghapusan klaim persalinan komplikasi yang dirujuk, persaingan tidak sehat, dan proses administrasi. Ketidakpuasan bidan dan hambatan implementasi kebijakan Jampersal memerlukan kerja sama kalangan stakeholder untuk berkoordinasi secara mendalam untuk implementasi kebijakan Jampersal yang lebih baik pada masa mendatang. The low service reimbursement indicates midwife unsatisfaction on policy implementation of delivery insurance in Purbalingga District. The objective of this study was to explore several cause factors of and to know the barrier problem on delivery insurance policy implementation at the ground level. This descriptive case study used qualitative data that collected in period March _ July 2012. The Informants of this research include four civil servant midwives and four non civil servant midwives. This research found six factors causes midwives unsatisfaction at Jampersal policy implementation in 2012 include reimbursement payment reduction, amount of service reimbursement; delivery service complication referral payment; unfair competition practice; long time waiting for the reimbursement payment; delivery service reimbursement administration process. The midwife unsatisfaction and the delivery insurance policy implementation barrier need collaboration among stakeholders to deeply coordination for better delivery insurance policy implementation in the future.
