In 2006, a video of a middle-aged man verbally assaulting a youth in a public bus thrust usergenerated content and YouTube into the public imagination in Hong Kong. Using the concept of legitimacy from institutional theory to qualitatively analyze newspaper commentaries about the incident, this study connects journalists’ narratives to the diffusion of usergenerated content by showing how they ...

In China, with increasing maturity of media and continuous emergence of new media, demand on media managers is urgent day by day. However, media management itself is a subject with combination of compound, pluralism, theory and practice. It is easy to train common journalists, but it is quite difficult to train media talents of high quality proficient in management. This article is going to mai...

This study presents Albert Burroni’s polygraphs as an algebraic and graphical description of first-order functional programs, where functions can have many outputs. We prove that polygraphic programs form a Turing-complete computational model. Using already-known termination orders for polygraphs, we define simple programs as a special class of polygraphs equipped with a notion of polynomial in...

A new type of ECR ion source-a gasdynamic ECR ion source-has been recently developed at the Institute of Applied Physics. The main advantages of such device are extremely high ion beam current with a current density up to 600-700 emA/cm(2) in combination with low emittance, i.e., normalized RMS emittance below 0.1 π mm mrad. Previous investigations were carried out in pulsed operation with 37.5...

An approach is proposed for computing the percentile points of the maximum of k independent Student’s t random variables. A simple program in R (a freely downloadable statistical software) is presented and its performance compared with other known approaches. Similar programs are presented for computing the percentile points of the componentwise maximum of k-variate t and k-variate normal vecto...

A NKS-B workshop on radioanalytical chemistry for radioecology and waste management was hold at Risø, Roskilde, Denmark in 16-20th November 2009. The workshop was organized as 3 days lectures and presentations and two days laboratory practice. 48 peoples participited the workshop, including 32 young participants from Denmark, Finland, Norway, Sweden, Lithuania and Ireland. This report gives a b...

A formal model is pr.:sented which represents the .~'tructure underlying temporal references" in natural language. Sei'ting as a framework for analysis o f tenses, time relations, and other references to time i~: language, the model consists o f a partially ordered set, called "'time" and successively def,:ned concepts such as "'tinw.segment", "duration "'~, "'time.segment relation", "'tense", ...

For bioscientists studying protein structure and function, the Protein Family Alignment Annotation Tool (Pfaat) is a useful and simple program for annotating collections of proteins. This open-source software includes methods for viewing and aligning protein families, and for annotating sequence structure and residues with known functions. It offers new options to aid the study of proteins, and...

The strong intellectual investment behind the definition of process algebras and the high abstraction level they can attain in formal specification still contrasts with their degree of penetration into software engineering practice, but also with the relatively limited number of other fields of fundamental science where these models have played some role. An emerging area in which process algeb...

New computer systems like smartphones and tablets, are entering the market at an ever-accelerating pace. This brings enormous pressure on the product development teams to shorten the time-to-market. Driven by increasing design complexity and decreasing time-to-market, it demands innovative approaches to accelerating hardware design simulation, verification, and debugging. Recently the hardw...
