The way we talk can influence how we are perceived by others. Whereas previous studies have started to explore the influence of social goals on syntactic alignment, in the current study, we additionally investigated whether syntactic alignment effectively influences conversation partners' perception of the speaker. To this end, we developed a novel paradigm in which we can measure the effect of...

The purpose of this study was to check the validity and the intra- and inter-evaluators reproducibility of the Sargent Jump Test, as an instrument of explosive strength measurement of soccer players of the sub-15 class. Forty-five soccer players were randomly selected from different clubs competing in the local soccer championship. All subjects performed one test on the same jump platform model...

Usability evaluation is essential to user-centred design, yet evaluators who analyse the same usability test sessions have been found to identify substantially different sets of usability problems. We revisit this evaluator effect by having 19 experienced usability professionals analyse videorecorded test sessions with five users. Nine participants analysed moderated sessions; ten participants ...

This paper presents an online partial evaluator with a mechanism to handle I/O-type side-e ects using preactions, and reports our experiment of using the partial evaluator as a compiler for the re ective language Black we are designing. Black is a Scheme-based re ective language, which allows user programs to access and modify its metalevel interpreter (or the language semantics) from within th...

We extend our correspondence between evaluators and abstract machines from the pure setting of the λ-calculus to the impure setting of the computational λ-calculus. We show how to derive new abstract machines from monadic evaluators for the computational λ-calculus. Starting from (1) a generic evaluator parameterized by a monad and (2) a monad specifying a computational effect, we inline the co...

It is well known that the knapsack cryptosystem is a type of public key cryptosystems. It is based on the well known mathematical concept, i.e., the choosing of one way function. Many Knapsack cryptosystems were invented in the last 20 years, and many attacking methods were invented as a counterattack against the developed knapsack cryptosystems. All the attacking methods aim towards breaking t...

The role of a university professor is multifaceted; as teacher, facilitator, assessor, evaluator, models of learning themselves as self-directed learners, addressing several key competencies for the effective teacher. It is not only about the transmission of knowledge, facts and skills but also about understanding how a student learns and being able to adapt and differentiate the delivery to pe...
