The Effect of Immigration on the School Performance of Natives: Cross Country Evidence Using PISA Test Scores We study whether a higher share of immigrant pupils affects the school performance of natives using aggregate multi-country data from PISA. We find evidence of a negative and statistically significant relationship. The size of the estimated effect is small: doubling the share of immigra...

Using 1990 Census microdata, we explore ethnic, racial and immigrant differences in private school attendance. We find high rates of private school attendance among white natives, white immigrants, and Asian natives. In contrast, we find low private school rates among black and Hispanic natives and immigrants, Asian immigrants, and other natives. Variations in income per capita and especially p...

Previous research has reached mixed conclusions about whether higher levels of immigration reduce the wages of natives. This paper reexamines this question using data from the Current Population Survey and the Immigration and Naturalization Service and focuses on differential effects by skill level. Using occupation as a proxy for skill, we find that an increase in the fraction of workers in an...

This paper focuses on how we can design Ubiquitous Information Systems (UIS) for digital natives. Digital natives are those who have grown up in a digital world, where the use of information and communications technologies is pervasive and ubiquitous, and where these technologies are used in organisational and personal contexts. Digital natives, unlike digital immigrants, like new technologies ...

This study investigates the extent of labour market competition among native Dutch workers and ethnic minorities, using national survey of the SEO and the Population statistics of the CBS. Firstly, the direct e¤ect of immigrants on local labour markets is considered. It is shown that ethnic minorities from developing countries have a positive e¤ect on the earnings of high skilled natives and an...

Spelling errors in digital documents are often caused by operational and cognitive mistakes, or by the lack of full knowledge about the language of the written documents. Computer-assisted solutions can help to detect and suggest replacements. In this paper, we present a new string distance metric for the Persian language to rank respelling suggestions of a misspelled Persian word by considerin...

OBJECTIVE Persian leek is one of the most widely used herbal foods among Iranians. In this study, effects of oral administration of Persian leek on plasma and liver lipids were examined in hamster. MATERIALS AND METHODS Male Syrian hamsters were randomly divided into three groups: control (standard diet), high fat control (high-fat/high-cholesterol diet), Persian leek (high-fat/high-cholester...

BACKGROUND Fear of falling may be related to falling during stroke onset. The Fall Efficacy ScaleInternational (FES-I) with excellent psychometric properties, is an instrument developed to assess patients' concerns about fallings. The aim of this study was to determine validation of this scale in Iranian patients with stroke. METHODS The "forward-backward" procedure was applied to translate t...

We present a dependency parser for Persian, called ParsPer, developed using the graph-based parser in the Mate Tools. The parser is trained on the entire Uppsala Persian Dependency Treebank with a specific configuration that was selected by MaltParser as the best performing parsing representation. The treebank’s syntactic annotation scheme is based on Stanford Typed Dependencies with extensions...
