Massive Multiplayer Online Role-Playing Games represent very complex applications, and their growing popularity makes them an important commercial factor in the entertainment area. However, the need to fulfil very highlevel technical and user requirements makes the development a risky task. We address these issues from a data management perspective with services to support the management of a p...

Video games are becoming more popular; there has been a particular rise in interest and use of massively multiplayer online role-playing games (MMORPGs). These games utilize avatar creation; avatars can be seen as the technological instantiation of the real person in the virtual world. Little research has been conducted on avatar creation. Although it is has been anecdotally postulated that you...

Utilizing the generalized factorization of twist-4 processes, we derive the modified heavy quark fragmentation function after considering the gluon radiation induced by multiple scattering in DIS. It is found that the mass effects of heavy quark may reduce the gluon formation time and change the medium size dependence of heavy quark energy loss. The radiative energy loss is also significantly s...

In this paper we investigated the levels of addiction and personal data disclosure within Massively Multiplayer Online Role Playing Game environments (MMORPG’s). The study made use of an online survey, a combination of a six point behavioural addiction framework, Self Determination Theory and Impression Management theory to assess addictive behaviour and consequential data disclosure amongst a ...

The Lovász Local Lemma is a sieve method to prove the existence of certain structures with certain prescribed properties. In most of its applications the Lovász Local Lemma does not supply a polynomial-time algorithm for finding these structures. Beck was the first who gave a method of converting some of these existence proofs into efficient algorithmic procedures, at the cost of loosing a litt...

We consider the problem of routing a message in a mesh network with faulty nodes. The number and positions of faulty nodes is unknown. It is known that a flooding strategy like expanding ring search can route a message linear in the minimum number of steps h while it causes a traffic (i.e. the total number of messages) of O(h). For optimizing traffic a single-path strategy is optimal producing ...

While some service providers of Massively Multiplayer Online Role-Playing Games (MMORPGs) lose significant numbers of players over time, others maintain a strong growth trajectory. Drawing from the Uses and Gratifications Theory and the Need to Belong theory, we believe that an individual’s Perceived Belonging (i.e., the degree to which a person feels connected to and accepted by others) positi...

Since the action selection mechanism chooses the next fired action, we claim that it is the place where the character’s behaviour is defined. We propose an ASM wich is able to produce believable and reusable behaviours for situated cognitive characters. It is defined as a combination of several motivations. It is modular and robust to evolutions of the environment, hence the designer task of bu...

Massively Multi-player Online Role-Playing Games (MMORPGs) and Massively Multiplayer Online games (MMOs) are complex socio-technical distributed systems. In these environments, a huge amount of players interact to have fun and develop their characters. Looting systems have been developed to help allocating valuable in-game objects, gained after finishing quests, as fairly as possible among the ...

An empirical model of player motivations in MMORPGs provides the foundation to understanding and assessing how players differ from one another and how motivations of play relate to age, gender, usage patterns and in-game behaviors. In the current study, a factor analytic approach was used to create an empirical model of player motivations. The analysis revealed 10 motivation subcomponents that ...
