FACTORS AFFECTING LOCAL AUTHORITIES’ WASTE MANAGEMENT (THE CASE OF KATUMBAN DISTRICT, SAMUTSAKORN PROVINCE, THAILAND)
Authors: Suwandej Niyom 
Published: June 2019

The purpose of this article is to study the factors that affect the participation in management of community waste. Studying the factors affecting community participation in waste management might become a way to find how to manage wastes in the community of the Khaerai Sub-district, Katumban District, Samutsakorn Province of Thailand. This research is designed as a mixed research, that is, both qualitative and quantitative. The tools used to collect quantitative and qualitative data were as follows: 1) The tool used in quantitative collection is a questionnaire divided into 4 sections as follows. Part 1: Analysis of public data on the Khaerai Sub-district Administration Organization. Part 2: Analysis of knowledge on waste management in the community of Khaerai Sub-district. Part 3: Analysis of the factors affecting people’s participation in waste management in the sub-district in question. Part 4: Analysis of household solid waste management in Khaerai Sub-district. 2) Tools used for collection of qualitative data included observations and in-depth interviews on the issues related to community’s involvement in waste management.
Our research results demonstrate that most of the people in the sub-district in question are involved in reducing the volume of household waste. They always participate in separation of waste types before disposing them. The study on the solid waste management system of Khaerai Sub-district Administration Organization found that the Administration applies comprehensive community waste management, integrated with waste management. To manage the garbage at its source, dividing the garbage into four categories is used (thus, there are four cans). This helps collecting solid waste more efficiently and thus reduce the contamination of that waste that potentially can be reused. The focus should be maintained on waste sorting and also on organization of the related projects and activities. Additional measures may include providing a new waste facility for future solid waste and also promoting more ways to get rid of waste at its source. Using the participatory principles in waste management gives people more freedom in options’ selection, and this, in its turn, may boost the efficiency of waste collection and waste management overall.

Thai public sector always described as a highly centralized system, with an inflexible hierarchical structure and high levels of formal relationships channeling its communications through public enterprises and institutions. Even establishing the local administration system as an approach of decentralization, is still highly connected and governed by the central government. On the other hand, innovation in public sector studies and application in last two decades gained much interest from scholars, practitioners and even leaders and policy makers as an approach to enhance public sector efficiency and effectiveness. Accordingly, this study aims to explore innovation in the public sector in Thesaban Mueang Phetchabun Thailand.
It can represent the public sector in Thailand on a larger scale. The study evaluates the laws, structures and dynamics that constitute the framework of the local administration system. Furthermore, it explores the main constraints on innovation within the system. To develop and support the argument, which emerges from the literature review, this study employs qualitative research methods, namely interviews, as a method to collect data from various informants working in and/or with the public sector.
The results of the study indicated that the innovative administration implemented by local administrative organization was distinct and different from each other based on its own main mission. Specifically, while the top-down innovation was implemented by big local administrative organizations. The initiating process comprised three steps. First, there were meetings among involved personnel. After that, there was an attempt to network with external organizations. Finally, there were processes of monitoring and follow-up evaluation as well as the establishment of learning center. Concerning factors in relation to initiating processes, they comprised six factors which included leadership for change, corporate culture, knowledge and competency of practitioners, public participation, supports from external organizations, and social capitals.

This research aims to study the content requirements when it comes to improvement of English communication skills of Thai laborers who are preparing to enter the labor market in Ranong province, Thailand. This study is a qualitative research since the researchers have used in-depth interviews as the key research instrument and have also applied the triangulation method to check for data validity. The key informants were 20 people including the unemployed Thais and also local university students. The skills in question have been divided into four rather traditional categories: listening, speaking, reading and writing skills. The research outcomes demonstrate that firstly, most of the unemployed Thai laborers would like to improve their listening skills so that to be able to follow basic instructions and orders at work. Secondly, regarding the speaking skills, most of the informants would like to improve their job interviewing skill. Thirdly, most of Thai laborers would like to develop their reading skill, their key motivation being to read job advertisements. And also - to be able to fill in job application forms is what most of Thai laborers would like to learn. Overall, Thai workers fully admit they are having difficulties in using all four types of skills. However, our research findings also reveals that Thai workers have serious troubles with the speaking skills, mostly because of the wrong usage of English grammar.
The authors of this study would like to recommend both public and private organizations in Ranong area to become more aware of the English communication skill problem of the local Thai workers. The results of this study should be used as a guideline in promoting and developing the programs aimed at improving English communication skills of the current and prospective Thai workers in the province in question.
Benchmark for the Determination of the Positronium Formation Fraction in Interstellar Media

Published: June 2019

Abstract
Relativistic positrons (>1 MeV) are produced from many sources in the Galaxy. Observations of positrons rely on the characteristic gamma-rays emitted from their annihilation with an electron, and the dominant annihilation pathways are determined by low-energy (<1 keV) processes. Thus, detailed information on the transport of positrons from high to low energies is required to accurately determine the propagation of positrons in the interstellar medium. This work considers model cross sections with variable parameters to provide a benchmark for several quantities, including the positronium formation fraction and time to reach subpositronium threshold energies. We simulate these processes using Monte Carlo codes within the cold collisional regime and carefully consider the energy sharing in ionization events that leads us to highlight the need for accurate ionization cross sections, which are differential in energy loss. We include tabulated values so that our benchmark values can be reproduced by other transport codes.

Abstract
Cosmological cluster-scale strong gravitational lensing probes the mass distribution of the dense cores of massive dark matter halos and the structures along the line of sight from background sources to the observer. It is frequently assumed that the primary lens mass dominates the lensing, with the contribution of secondary masses along the line of sight being neglected. Secondary mass structures may, however, affect both the detectability of strong lensing in a given survey and modify the properties of the lensing that is detected. This paper focuses on the former: we utilize a large cosmological N-body simulation and a multiple lens plane (and many-source plane) ray-tracing technique to quantify the influence of line-of-sight structures on the detectability of cluster-scale strong lensing in a cluster sample with a mass limit that encompasses current cluster catalogs from the South Pole Telescope. We extract both primary and secondary halos from the “Outer Rim” simulation and consider two strong lensing realizations—one with only the primary halos included, and the other with the full mass light cone for each primary halo, including all secondary halos down to a mass limit more than an order of magnitude smaller than the smallest primary halos considered. In both cases, we use the same source information extracted from the Hubble Ultra Deep Field, and create realistic lensed images consistent with moderately deep ground-based imaging; the statistics of the observed strong lensing are extracted from these simulated images. The results demonstrate that down to the mass limit considered the total number of lenses is boosted by ∼13%–21% when considering the complete multi-halo light cone; the enhancement is insensitive to different length-to-width cuts applied to the lensed arcs. The increment in strong lens counts peaks at lens redshifts of z ∼ 0.6 with no significant effect at z < 0.3. The strongest trends are observed relative to the primary halo mass, with no significant effect in the most massive quintile of the halo sample, but increasingly boosting the observed lens counts toward small primary halo masses, with an enhancement greater than 50% in the least massive quintile of the halo masses considered.

Abstract
We present an analysis of the spectral shape and pulse profile of the accretion-powered pulsar 4U 1626−67 observed with Suzaku and Nuclear Spectroscopic Telescope Array (NuSTAR) during a spin-up state. The pulsar, which experienced a torque reversal to spin-up in 2008, has a spin period of ∼7.7 s. Comparing the phase-averaged spectra obtained with Suzaku in 2010 and with NuSTAR in 2015, we find that the spectral shape changed between the two observations: the 3–10 keV flux increased by ∼5%, while the 30–60 keV flux decreased significantly by ∼35%. Phase-averaged and phase-resolved spectral analysis shows that the continuum spectrum observed by NuSTAR is well described by an empirical negative and positive power law times exponential continuum with an added broad Gaussian emission component around the spectral peak at ∼20 keV. Taken together with the observed

value obtained from the Fermi/gamma-ray burst monitor data, we conclude that the spectral change between the Suzaku and NuSTAR observations was likely caused by an increase in the accretion rate. We also report the possible detection of asymmetry in the profile of the fundamental cyclotron line. Furthermore, we present a study of the energy-resolved pulse profiles using a new relativistic ray tracing code, where we perform a simultaneous fit to the pulse profiles assuming a two-column geometry with a mixed pencil- and fan-beam emission pattern. The resulting pulse profile decompositions enable us to obtain geometrical parameters of accretion columns (inclination, azimuthal and polar angles) and a fiducial set of beam patterns. This information is important to validate the theoretical predictions from radiation transfer in a strong magnetic field.

Abstract
We present observations of the Trumpler 14/Carina I region carried out using the Stratospheric Terahertz Observatory 2. The Trumpler 14/Carina I region is in the western part of the Carina Nebula Complex (CNC), which is one of the most extreme star-forming regions in the Milky Way. We observed Trumpler 14/Carina I in the 158 μm transition of [C ii] with a spatial resolution of 48″ and a velocity resolution of 0.17 km s−1. The observations cover a 0.°25 by 0.°28 area with central position l = 297.°34, b = −0.°60. The kinematics show that bright [C ii] structures are spatially and spectrally correlated with the surfaces of CO clouds, tracing the photodissociation region (PDR) and ionization front of each molecular cloud. Along seven lines of sight (LOSs) that traverse Tr 14 into the dark ridge to the southwest, we find that the [C ii] luminosity from the H ii region is 3.7 times that from the PDR. In the same LOS, we find in the PDRs an average ratio of 1 : 4.1 : 5.6 for the mass in atomic gas : dark CO gas : molecular gas traced by CO. Comparing multiple gas tracers, including H i 21 cm, [C ii], CO, and radio recombination lines, we find that the H ii regions of the CNC are well described as H ii regions with one side freely expanding toward us, consistent with the Champagne model of ionized gas evolution. The dispersal of the GMC in this region is dominated by EUV photoevaporation; the dispersal timescale is 20–30 Myr.
The Brightest Galaxies at Cosmic Dawn from Scatter in the Galaxy Luminosity versus Halo Mass Relation
Authors: Ren Keven , Trenti Michele , Mason Charlotte A. 
Published: June 2019

Abstract
The Ultraviolet Luminosity Function (UVLF) is a key observable for understanding galaxy formation from cosmic dawn. There has been considerable debate on whether Schechter-like LFs (characterized by an exponential dropoff at the bright end) that describe the LF in our local universe are also a sufficient description of the LF at high redshifts (z > 6). We model the UVLF over cosmic history with a semi-empirical framework and include a log-normal scatter, Σ, in galaxy luminosities with a conditional luminosity function approach. We show that stochasticity induces a flattening or a feedback scale in the median galaxy luminosity versus halo mass relation, L

c
(M

h
), to account for the increase of bright objects placed in lower-mass halos. We observe a natural broadening in the bright-end exponential segment of the UVLF for z > 6 if processes that regulate star formation acts on the same mass scale as at z ∼ 5, where the degree of broadening is enhanced for larger Σ. Alternatively, if the bright-end feedback is triggered at a near-constant luminosity threshold, the feedback threshold occurs at progressively lower halo masses with increasing redshift, due to galaxies being more luminous on average at a fixed halo mass from rapid halo assembly. Such feedback results in an LF shape with a bright-end closer to that of a Schechter function. We include predictions for the z > 8 UVLFs from future all-sky surveys such as WFIRST, which has the potential to both quantify the scatter and type of feedback, and provide insight behind the mechanisms that drive star formation in the early universe.
Modeling the Spatial Distribution and Origin of CO Gas in Debris Disks

Published: June 2019

Abstract
The detection of gas in debris disks raises the question of whether this gas is a remnant from the primordial protoplanetary phase, or released by the collision of secondary bodies. In this paper we analyze ALMA observations at 1″–1.″5 resolution of three debris disks where the 12CO(2–1) rotational line was detected: HD 131835, HD 138813, and HD 156623. We apply the iterative Lucy–Richardson deconvolution technique to the problem of circumstellar disks to derive disk geometries and surface brightness distributions of the gas. The derived disk parameters are used as input for thermochemical models to test both primordial and cometary scenarios for the origin of the gas. We favor a secondary origin for the gas in these disks and find that the CO gas masses (

M

) require production rates (∼5 × 10−7
M
⊕ yr−1) similar to those estimated for the bona fide gas-rich debris disk β Pic.
Is Bremsstrahlung a Possible Mechanism to Explain the Thermal Feature in the GRB 130925A X-Ray Afterglow?
Authors: Liu Jie-Ying , Mao Jirong 
Published: June 2019

Abstract
It has been reported that some X-ray spectra of gamma-ray burst (GRB) afterglows cannot be fitted by a simple power law. A blackbody component is added to precisely fit the thermal feature in these spectra. Alternatively, we propose that bremsstrahlung radiation can also be one possible mechanism to explain the thermal component of the GRB X-ray afterglow. In particular, we examine the X-ray afterglow of the ultra-long GRB 130925A in this paper. By our calculation, we find that the X-ray thermal component observed by both Swift-XRT and NuSTAR can be well explained by the bremsstrahlung radiation. Our results indicate that the GRBs with the bremsstrahlung emission in the X-ray afterglow could be born in a metal-rich and dusty environment.

The continental and marine territories of Uruguay are characterised by a rich convergence of multiple biogeographic ecoregions of the Neotropics, making this country a peculiar biodiversity spot. However, despite the biological significance of Uruguay for the South American subcontinent, the distribution of biodiversity patterns in this country remain poorly understood, given the severe gaps in available records of geographic species distributions. Currently, national biodiversity datasets are not openly available and, thus, a dominant proportion of the primary biodiversity data produced by researchers and institutions across Uruguay remains highly dispersed and difficult to access for the wider scientific and environmental community. In this paper, we aim to fill this gap by developing the first comprehensive, open-access database of biodiversity records for Uruguay (Biodiversidata), which is the result of a large-scale collaboration involving experts working across the entire range of taxonomic diversity found in the country.As part of the first phase of Biodiversidata, we here present a comprehensive database of tetrapod occurrence records native from Uruguay, with the latest taxonomic updates. The database provides primary biodiversity data on extant Amphibia, Reptilia, Aves and Mammalia species recorded within the country. The total number of records collated is 69,380, spanning 673 species and it is available at the Zenodo repository: https://doi.org/10.5281/zenodo.2650169. This is the largest and most geographically and taxonomically comprehensive database of Uruguayan tetrapod species available to date and it represents the first open repository for the country.

Published: June 2019

Dans les Pyrénées-Orientales, trois villages célèbrent, en fin d’hiver, la fête de l’Ours. De jeunes hommes costumés et grimés en ours, entourés de chasseurs, impliquant l’ensemble de la communauté villageoise dans la représentation, parcourent les rues et poursuivent les jeunes filles qu’ils font mine d’enlever. La fête de Prats-de-Mollo, analysée ici, met en scène une série d’affrontements qui, relevant de la « feintise ludique », ont tous les paradoxes de la mimesis.
Le Petit Poucet digital ethnographié

Published: June 2019

Dans notre monde numérisé, « Suivre les acteurs », la devise historique de l’ethnographie inspirée par la théorie de l’acteur-réseau, signifie désormais suivre les acteurs et leurs traces, et, à travers ces traces, suivre leurs dispositifs, leurs avatars, leurs identités et leurs pratiques dupliquées. Les acteurs contemporains sont comme le Petit Poucet : ils peuvent disparaître ou devenir inobservables, et laisser dans la forêt marchande des traces numériques qui fonctionnent comme les cailloux blancs et les miettes de pain de jadis, dans la mesure où on peut les suivre pour retrouver des informations sur leurs pratiques et sur leurs identités. Sur le marché de la presse examiné ici, on rencontrera une foule de Petits Poucets adultes et indépendants, lisant France Vision, un grand hebdomadaire d’information français, et visionnant (ou non) des vidéos accessibles à travers les QR codes imprimés sur ses pages. À partir de la collecte de traces numériques recueillies à l’échelle nationale au cours d’une période de 10 mois (juin 2013-mars 2014), l’article présente un ensemble de résultats montrant ce que l’on peut apprendre grâce à une ethnographie renouvelée des traces de QR codes.
