• NON-LINEAR REGRESSION MODELS

This is a survey of non-linear regression models, with an emphasis on the theory of estimation and hypothesis testing rather than computation and applications, although there will be some discussion of the last two topics. For a general discussion of computation the reader is referred to Chapter 12 of this Handbook by Quandt. My aim is to present the gist of major results; therefore, I will sometimes omit proofs and less significant assumptions. For those, the reader must consult the original sources....

• The information content of central bank interest rate projections: Evidence from New Zealand - 2012

We test three hypotheses concerning the impact of loan market competition on euro area banks’ loan and deposit rates. First, we examine the effect of loan market competition on the level on bank loan and deposit rates; second, using a panel error-correction model (ECM) we estimate the effect of loan market competition on the long-run equilibrium pass-through of bank interest rates to changes in corresponding market interest rates; third, we also test the impact of competition in the loan market on the immediate adjustment of bank interest rates to changes in market interest rates....

• Báo cáo khoa học: "Examining the Content Load of Part of Speech Blocks for Information Retrieval"

We investigate the connection between part of speech (POS) distribution and content in language. We deﬁne POS blocks to be groups of parts of speech. We hypothesise that there exists a directly proportional relation between the frequency of POS blocks and their content salience. We also hypothesise that the class membership of the parts of speech within such blocks reﬂects the content load of the blocks, on the basis that open class parts of speech are more content-bearing than closed class parts of speech.

• Design and evaluation of a Facebook game for selfdirected e-learning

Social networking sites (SNSs) such as Facebook have a potential to become a valuable learning environment. Facebook games with appropriate instructional design may provide players with better learning experiences and outcomes. Using an effective educational Facebook game, we aimed to explore the educational effects of Facebook games as self-directed e-learning environments. We tested our hypotheses on a sample of 73 undergraduates (42 females). The participants completed the Facebook game and self-administered questionnaires over a 3-week period.
