Technological Developments

Developments in electronic communications are drastically changing what it means to be human and to interact with humans. The value of recent technological developments to artists is more than doing more, faster and better; it is also the ability to highlight and elevate humanness in new ways through art, even by appearing to replace the real with the virtual. New tools don’t simply replace humans, they allow human creators to shift into new realms of creation: creating dynamic systems and worlds instead of static products. This chapter will give consideration to the different types of presence manifest in various communications formats, stage presence in technology-mediated performance, and several artworks that bring new light to the artist’s approach to virtual worlds as a kind of counterpoint with reality.

Linguistic Means

The paper deals with the linguistic means that had helped us to adapt to virtual reality and that now seem to us to have existed always. The words and expressions didn’t appear out ofnowhere – they were imported from our everyday language where they had been used for naming objects and processes in the real world. Thus the new realm, such as the physical one, was marked by language signs that determine the nature and the structure of our conception of the Internet which is interpreted generally as a physical space (different types of the latter). These signs are described here in terms of conceptual metaphor theory. Recently we have been dealing with some new, “web-born” expressions. It is shown that such expressions are no more limited to the describing of the Internet and are extended to the real world; it can be said they provide us with new tools to interpret the “old” reality. Thereby we can see the very moment when the source and the target domains (that is real and virtual worlds) are switching their places.

World Concept

As an answer to these questions, this chapter will define the virtual world concept, distinguish the different types of virtual worlds, and make a comparative analysis between them in order to bring out the features aimed at helping teachers to adopt them in their classes. In particular, we will focus our choice of virtual world environments on open source platforms. As the prevalence of mobile learning increases, this chapter also describes the m-learning scope, its contextualisation and advantages, as well as the learning methods. Finally, the relation of those methods with social virtual worlds is also discussed.

A virtuális szociális világok, úgy mint a Second Life, egyre nagyobb népszerűségre téve szert, hamar az üzleti érdeklődés középpontjában találták magukat. A szerző célja, hogy feltérképezze a virtuális identitás és a fogyasztói magatartás közötti kapcsolat mibenlétét a Second Life világában. Ezért először bemutatja, hogy miként működik a Second Life és milyen jellemzőkkel rendelkezik. Másodszor ismerteti, hogy az on-line identitásalkotás miként befolyásolja üzleti szempontból az individuális viselkedést. A Second Life vizsgálata során a virtuális identitás fogalmát használja föl, mely összevethető az egyén valódi életbeli identitásával. Harmadszor: rátér a kutatási részre, amely során a Second Life világában kialakított identitás jellemzőit vizsgálta. Négy virtuális identitástípust azonosított, melyeknek más és más kapcsolata van a virtuális fogyasztás jelenségével. Végezetül: kiemeli azokat az eredményeket és megállapításokat, melyeket a vállalatoknak különösképpen figyelembe kell venniük a pszichológiai nézőpont szempontjából ahhoz, hogy eredményesen szerepeljenek a virtuális világokban. ________ Given their increasing popularity, virtual worlds, such as Second Life, attracted the attention of the business media. The aim of the present article is to explore the relationship between virtual identity and consumer behaviour in Second Life. First, the author reviews Second Life functions and particular characteristics. Second, he illustrates how online identity construction affects one’s behaviour in such environments from a business perspective. Third, the author demonstrates his findings associated with identity construction in Second Life. More specifically, four different types of virtual identities can be identified, each with slightly different implications toward virtual consumption. Finally, he highlights the major points to which companies should pay particular attention in their virtual social world activities, focusing on the psychological mechanisms that influence people’s online behaviour and thinking.

Bystander Awareness

Head-mounted displays (HMDs) increase immersion into virtual worlds. The problem is that this limits headset users' awareness of bystanders: headset users cannot attend to bystanders' presence and activities. We call this the HMD boundary. We explore how to make the HMD boundary permeable by comparing different ways of providing informal awareness cues to the headset user about bystanders. We adapted and implemented three visualization techniques (Avatar View, Radar and Presence++) that share bystanders' location and orientation with headset users. We conducted a hybrid user and simulation study with three different types of VR content (high, medium, low interactivity) with twenty participants to compare how these visualization techniques allow people to maintain an awareness of bystanders, and how they affect immersion (compared to a baseline condition). Our study reveals that a see-through avatar representation of bystanders was effective, but led to slightly reduced immersion in the VR content. Based on our findings, we discuss how future awareness visualization techniques can be designed to mitigate the reduction of immersion for the headset user.

The Laplace transform of the extinction time is determined for a general birth and death process with arbitrary catastrophe rate and catastrophe size distribution. It is assumed only that the birth rates satisfyλ0= 0,λj> 0 for eachj> 0, and. Necessary and sufficient conditions for certain extinction of the population are derived. The results are applied to the linear birth and death process (λj=jλ, µj=jμ) with catastrophes of several different types.

Abstract We argue that Tomasello's account overlooks important psychological distinctions between how humans judge different types of moral obligations, such as prescriptive obligations (i.e., what one should do) and proscriptive obligations (i.e., what one should not do). Specifically, evaluating these different types of obligations rests on different psychological inputs and has distinct downstream consequences for judgments of moral character.

Complete Interpretation

Previous freeze fracture results on the intact giant, amoeba Chaos carolinensis indicated the presence of a fibrillar arrangement of filaments within the cytoplasm. A complete interpretation of the three dimensional ultrastructure of these structures, and their possible role in amoeboid movement was not possible, since comparable results could not be obtained with conventional fixation of intact amoebae. Progress in interpreting the freeze fracture images of amoebae required a more thorough understanding of the different types of filaments present in amoebae, and of the ways in which they could be organized while remaining functional.The recent development of a calcium sensitive, demembranated, amoeboid model of Chaos carolinensis has made it possible to achieve a better understanding of such functional arrangements of amoeboid filaments. In these models the motility of demembranated cytoplasm can be controlled in vitro, and the chemical conditions necessary for contractility, and cytoplasmic streaming can be investigated. It is clear from these studies that “fibrils” exist in amoeboid models, and that they are capable of contracting along their length under conditions similar to those which cause contraction in vertebrate muscles.

Different Cell Types

Various types of intermediate-sized (10-nm) filaments have been found and described in many different cell types during the past few years. Despite the differences in the chemical composition among the different types of filaments, they all yield common structural features: they are usually up to several microns long and have a diameter of 7 to 10 nm; there is evidence that they are made of several 2 to 3.5 nm wide protofilaments which are helically wound around each other; the secondary structure of the polypeptides constituting the filaments is rich in ∞-helix. However a detailed description of their structural organization is lacking to date.
