Bank Privitization in Vietnam: Examining Changes to Management in Vietnam\u27s New Banking Law, Decree No. 59/2009/ND-CP

Due to its WTO obligations, by 2010 Vietnam must open its banking system to the world. As a result, the nation attempted to drastically modernize its state owned banks through partial privatization. This partial privatization, locally translated as equitization, proposed serious challenges to the existing legal infrastructure facilitating banks. To cope with these new challenges, in September 2009, Vietnam’s new banking law, Decree 59/2009/ND-CP, was passed. An important change in the new banking law is its stricter regulation on the qualifications of managers. It is suspected that such regulation signals the nation’s resistance to surrender control over its banks and commit to reforms. The new banking law also further relies on the problematic Penal Code and the Criminal Procedure Code. Faulty Penal and Criminal Procedure Codes can lead to fraudulent lawsuits and managers losing their positions. In spite of its problems, the new banking law is workable and a step in the right direction. By relying on existing management laws, as opposed to those introduced by the new banking law, and upgrading the Penal and Criminal Procedure Codes, many of the potential problems created by the new banking law can be resolve

A new approach for the ortho-positronium lifetime determination in a vacuum cavity

Currently, the experimental uncertainty for the determination of the ortho-positronium (o-Ps) decay rate is at 150 ppm precision; this is two orders of magnitude lower than the theoretical one, at 1 ppm level. Here we propose a new proof of concept experiment aiming for an accuracy of 100 ppm to be able to test the second-order correction in the calculations, which is $\simeq 45\left(\frac{\alpha}{\pi}\right)^2\approx 200$ ppm. The improvement relies on a new technique to confine the o-Ps in a vacuum cavity. Moreover, a new method was developed to subtract the time dependent pick-off annihilation rate of the fast backscattered positronium from the o-Ps decay rate prior to fitting the distribution. Therefore, this measurement will be free from the systematic errors present in the previous experiments. The same experimental setup developed for our recent search for invisible decay of ortho-positronium is being used. The precision will be limited by the statistical uncertainty, thus, if the expectations are fulfilled, this experiment could pave the way to reach the ultimate accuracy of a few ppm level to confirm or confront directly the higher order QED corrections. This will provide a sensitive test for new physics, e.g. a discrepancy between theoretical prediction and measurements could hint the existence of an hidden sector which is a possible dark matter candidate.Comment: 12 pages, 8 Figures, prepared for the proceedings of the PSAS2018 conference, Vienna (Austria

Matching problem for primary and secondary signals in dual-phase TPC detectors

The problem of matching primary and secondary light signals, belonging to the same event, is presented in the context of dual-phase time projection chambers. In large-scale detectors, the secondary light emission could be delayed up to order of milliseconds, which, combined with high signal rates, could make the matching of the signals challenging. A possible approach is offered in the framework of the Stable Marriage and the College Admission problem, for both of which solutions are given by the Gale-Shapley algorithm.Comment: 18 pages, 8 figure

First test of a high voltage feedthrough for liquid Argon TPCs connected to a 300 kV power supply

Voltages above a hundred kilo-volt will be required to generate the drift field of future very large liquid Argon Time Projection Chambers. The most delicate component is the feedthrough whose role is to safely deliver the very high voltage to the cathode through the thick insulating walls of the cryostat without compromising the purity of the argon inside. This requires a feedthrough that is typically meters long and carefully designed to be vacuum tight and have small heat input. Furthermore, all materials should be carefully chosen to allow operation in cryogenic conditions. In addition, electric fields in liquid argon should be kept below a threshold to reduce risks of discharges. The combination of all above requirements represents significant challenges from the design and manufacturing perspective. In this paper, we report on the successful operation of a feedthrough satisfying all the above requirements. The details of the feedthrough design and its manufacturing steps are provided. Very high voltages up to unprecedented voltages of -300 kV could be applied during long periods repeatedly. A source of instability was observed, which was specific to the setup configuration which was used for the test and not due to the feedthrough itself.Comment: 13 pages, 9 figure

Sensitivity potential to a light flavor-changing scalar boson with DUNE and NA64μ\mu

In this work, we report on the sensitivity potential of complementary muon-on-target experiments to new physics using a scalar boson benchmark model associated with charged lepton flavor violation. The NA64$\mu$ experiment at CERN uses a 160-GeV energy muon beam with an active target to search for excess events with missing energy and momentum as a probe of new physics. At the same time, the proton beam at Fermilab, which is used to produce the neutrino beam for the Deep Underground Neutrino Experiment (DUNE) will also produce a high-intensity muon beam dumped in an absorber. Combined with the liquid Argon Near Detector, the system could be used to search for similar scalar boson particles with a lower energy but higher intensity beam. We find that both NA64$\mu$ and DUNE could cover new, unexplored parts of the parameter space of the same benchmark model, providing a complementary way to search for new physics

COMMUNITY NARRATIVES OF SOCIAL TRAUMA – A Case Study of a Sitio in Mindanao

The article addresses social trauma in a conflict-affected community in Pikit, North Cotabato, Mindanao, in the Philippines. Through an analysis of narratives and community practices the study intends to answer the following question: How did armed conflict (organized violence) and internal displacement impact on the community and how did the community respond? The analysis of the interviews from the study shows that three themes were frequently used to describe and explain the state of the social fabric, i.e. how well it was functioning or how disrupted it was; namely, significant events in the community’s history; responses to harassment; and actors and coping. It is shown that organized violence, war and recurrent forced displacement of communities produce responses that form a complex pattern of suffering (social trauma) and resilience (positive transformation). The interviews give a fuller understanding of how social trauma is constructed and sustained in communities impacted by organized violence. The study of peoples’ narratives provides us with knowledge on how trauma is experienced and understood by the impacted community. The study shows that responses to organised violence may foster locally based adaptive processes that help the community to recover and responses that may be detrimental to the community’s social support system. To understand these processes, not as dualistic but as interwoven as social tissue, it is necessary to study how local narratives present problems and hope of a better future
