Atoms in boxes: from confined atoms to electron-atom scattering

We show that both confined atoms and electron-atom scattering can be described by a unified basis set method. The central idea behind this method is to place the atom inside a hard potential sphere, enforced by a standard Slater type basis set multiplied by a cutoff factor. For confined atoms, where the wall is placed close to the atomic nucleus, we show how the energy of the highest occupied atomic orbital and the static polarizability of helium and neon atoms evolve with the confinement radius. To our knowledge, these are the first confined atom polarizability calculations that include correlation, through the use of time-dependent density-functional theory. By placing the atom in a large spherical box, with a wall outside the electron density, we obtain scattering phase shifts using a recently developed method [M. van Faassen, A. Wasserman, E. Engel, F. Zhang, and K. Burke, Phys. Rev. Lett. {\bf 99}, 043005 (2007)]. We show that the basis set method gives identical results to previously obtained phase shifts for $e$-H and $e$-He${}^{+}$ scattering.Comment: 8 pages, 6 figures, submitted to Journal of Chemical Physic

The Problems of Accounting in a Public Institution: The Case of Slovenia

In the article the author determines that, due to changes during the privatisation process, the Slovenian framework for public institution accounting is unable to assure the relevant presentation of costs, benefits and effects. She therefore proposes certain changes based on solutions applied in the private sector accounting practices. Her conclusions and recommendations, however, are based on a need for a true and fair measurement of a public institution’s results. The recommended way to achieve this goal is the proper application of solutions included in the International Public Sector Accounting Standards issued by the International Public Sector Accounting Standards Board of the International Federation of Accountants.public institution, benefits, costs, effects, Accounting Act, Slovenian Accounting Standards, International Public Sector Accounting Standards, accrual principle

An improved exchange-correlation potential for polarizability and dissociation in DFT

We propose a novel approach to the problem of polarizabilities and dissociation in electric fields from the static limit of the Vignale-Kohn (VK) functional. We consider the response to the purely scalar part of the VK response potential.This potential has ground-state properties that notably improve over the full VK response density and over usual (semi-)local functionals. The correct qualitative behavior of our potentials means that it is expected to work well for polarizabilities in cases such as the H$_2$ chain, and it will also correctly dissociate open-shell fragments in a field.Comment: 4 pages, 3 figures; to appear in JC

Pengaruh Persepsi Kegunaan, Kemudahan Penggunaan Terhadap Penggunaan E-Filing Berkelanjutan Bagi Wajib Pajak Orang Pribadi Di Kota Palembang

The purpose of this study is to examine the effect perception of usability, perceived ease of use of sustainable e-filing. This study uses a type of associative research which is a study that aims to determine the relationship or influence between two or more variables. This study took an individual taxpayer population in Palembang. The sample was determined by using convenience sampling method of 100 individual taxpayers who use e-filing in Palembang. The data were collected by distributed the questionnaire. Hypothesis testing using multiple regression analysis method with SPSS ver program. 17 The results showed that the first hypothesis (H1) states that usability perceptions have a positive effect on the use of sustainable e-filing. The second hypothesis (H2) states that there was positive contribution betwewn perceived ease of use to the sustainable use of e-filing

Strategies and Measures for Sustainable Urban Transport Systems

Increasing sustainability of urban transport systems is a crucial objective of all strategic plans both at national and European level. Different strategies and measures can be adopted to improve the efficiency of transport systems, according to a large set of factors that can affect the results of the implemented actions. A comprehensive study has been carried out in order to define a methodology able to define effective and efficient strategies and measures, allowing to increase the sustainability level of different kinds of cities, from small-medium sized to large metropolitan areas. The methodology has been tested on a group of 50 Italian cities, whose characteristics have been analysed through an initial set of more than 200 indicators. Three main groups of indicators have been taken into account: State indicators, Sustainability indicators, Policy indicators. The main aim has been to identify existing relationships between Sustainability and Policy indicators for cities showing commonalities in terms of State indicators. A correlation analysis allowed to identify 53 relevant indicators from the initial set of 200, while a cluster analysis, based on a hierarchical model, allowed to group the cities into five different groups, according to their population size and density. Correlations between relevant indicators have also been analysed within each group, while linear regression models have allowed to describe some functional relations between Policy and Sustainability indicators. A benchmarking exercise has allowed to identify strategies and measures adopted by the best performers within each group, hence defining possible paths to a better sustainability level for the remaining cities. Finally, recommendations for a correct urban mobility planning procedures have been produce

Real-Time Search in the Laboratory and the Market

While widely accepted models of labor market search imply a constant reservation wage policy, the empirical evidence strongly suggests that reservation wages decline over the duration of a search spell. This paper reports the results of the first real-time search laboratory experiment. The controlled environment that subjects face is stationary, and the payoff-maximizing reservation wage is constant. Nevertheless, subjects' reservation wags decline sharply over time. We investigate two hypotheses to explain this decline: 1) searchers respond to the stock of accruing search costs, and 2) searchers experience nonstationary subjective costs of time spent searching. Our data support the latter hypothesis, and we substantiate this conclusion both experimentally and econometrically.Job Search; Reservation Wage; Experiment

ANALISIS PENGARUH INVESTASI INFRASTRUKTUR PUBLIK TERHADAP PERTUMBUHAN EKONOMI DI ACEH

Penelitian ini bertujuan untuk melihat bagaimana pengaruh investasi infrastruktur publik terhadap pertumbuhan Ekonomi di 23 Kabupaten/Kota Provinsi Aceh, dimana variabel bebasnya terdiri dari variabel investasi jalan, listrik dan air bersih sedangkan variabel terikatnya yaitu pertumbuhan ekonomi. Model analisis yang digunakan dalam penelitian ini adalah model analisis Coob-Douglas dengan metode analisis data panel dimana data yang digunakan adalah data dari tahun 2008 sampai tahun 2012. hasil penelitian menunjukan bahwa dengan menggunakan pengolahan data eviews 7 menunjukan variabel investasi jalan berpengaruh positif dengan p-value = 0.0053 < 0.05, sehingga dapat dikatakan bahwa investasi infrastruktur jalan berpengaruh signifikan terhadap pertumbuhan ekonomi di 23 kabupaten/kota Provinsi Aceh, sedangkan investasi infrastruktur listrik dan air bersih berpengaruh dengan tingkat signifikan 10 persen terhadap pertumbuhan ekonomi di 23 kabupaten/kota Provinsi Aceh. Melihat peran jalan, listrik dan air bersih sebagai kebutuhan penting dalam hidup masyarakat maka pemerintah hendaknya memberikan lebih untuk investasi infrastruktur pada sektor-sektor tersebut agar pertumbuhan ekonomi meningkat
