Social media profiles are telling examples of the everyday need for disclosure and concealment. The balance between concealment and disclosure varies across individuals, and personality traits might partly explain this variability. Experimental findings on the relationship between information disclosure and personality have been so far inconsistent. We thus study this relationship anew with 1,3...

18 which we denote by (j) and which does not depend on t as desired. Finally we have: TUNE n X j=1 p j max t T(t; j) n X j=1 p j r(j) = n X j=1 p j r(h + 2(q ? 1)(log q d (j) + 1)) n X j=1 p j r(h + 2(q ? 1)(log q 2d j + 1)) n X j=1 p j r(h + 2q(log q d j + 1)) = 2qr(log q n X j=1 p p j + n X j=1 p j log q 1 p p j) + (h + 2q)r 4qr log q n X j=1 p p j + (h + 2q)r where the third inequality follo...

In this paper, we present an annotation tool developed specifically for manual sentiment analysis of social media posts. The tool provides facilities for general and target based opinion marking on different type of posts (i.e. comparative, ironic, conditional) with a web based UI which supports synchronous annotation. It is also designed as a SaaS (Software as a Service). The tool’s outstandin...

This study assessed the potential influence of social desirability (SD) response bias on the E, N, and P EPQ-R scores at the level of individual items. The study was based on a bidimensional IRT model which was fitted in a large sample. This allowed a detailed analysis of both the internal validities of the items and the content of the items which were most affected by SD. The E items were leas...

BACKGROUND Prior studies on social capital and health have assessed social capital in residential neighbourhoods and communities, but the question whether the concept should also be applicable in workplaces has been raised. The present study reports on the psychometric properties of an 8-item measure of social capital at work. METHODS Data were derived from the Finnish Public Sector Study (N ...

Randomized response (RR) is a well-known method for measuring sensitive behavior. Yet this method is not often applied because: (i) of its lower efficiency and the resulting need for larger sample sizes which make applications of RR costly; (ii) despite its privacy-protection mechanism the RR design may not be followed by every respondent; and (iii) the incorrect belief that RR yields estimates...

In research on the social capital of individuals, there has been little standardisation of measurement instruments, and more emphasis on measuring social relationships than social resources. In this paper we propose two innovations. First, a new measurement method: the Resource Generator; an instrument with concretely worded items covering ‘general’ social capital in a population, which combine...

validation is an important enterprise especially when a test is a high stakes one. demographic variables like gender and field of study can affect test results and interpretations. differential item functioning (dif) is a way to make sure that a test does not favor one group of test takers over the others. this study investigated dif in terms of gender in the reading comprehension subtest (35 i...

In this work we present a novel item recommendation approach that aims at improving Collaborative Filtering (CF) in social tagging systems using the information about tags and time. Our algorithm follows a two-step approach, where in the first step a potentially interesting candidate item-set is found using user-based CF and in the second step this candidate item-set is ranked using item-based ...

this paper reports on the findings of a study designed to investigate the cultural and social complexities governing the compliment responses among the persian native speakers. 200 persian respondents took a 24-item discourse completion task (dct) while 15 native field workers were also set responsible for collecting the examples of complimenting exchanges they either observed or participated i...
