Stereoscopic telepointing to be employed inter alia in cooperative telework applications yields many benefits but also poses a number of problems addressed in a study with 96 subjects under four different conditions. For two conditions, 3D-input devices were designed implementing different input metaphors. The ‘Light Beam Metaphor’ is analogous to pointing to objects with a slide show pointer or laser pointer. The ‘Reference Space Metaphor’ provides the users with the possibility of pointing to details of an object in such a way as if a re-sized model of the object was present in front of them and within reach of their hands. The other two conditions were stereoscopic and monoscopic control conditions without pointers. The subjects' task was to identify differences between a remote and a local object within a limited time. The results show that the Light Beam Metaphor pointer was easier to handle and conformed to a larger degree to the users' expectations, whereas the Reference Space Metaphor pointer received better subjective ratings on efficiency and Telepresence. The analysis of the results of all four conditions established the benefits of 3D over 2D representations for object-oriented communicative situations in terms of appeal and the impression of depth.

This paper is a contribution to the growing literature on the role of projective identification in understanding couples' dynamics. Projective identification as a defence is well suited to couples, as intimate partners provide an ideal location to deposit unwanted parts of the self. This paper illustrates how projective identification functions differently depending on the psychological health of the couple. It elucidates how healthier couples use projective identification more as a form of communication, whereas disturbed couples are inclined to employ it to invade and control the other, as captured by Meltzer's concept of "intrusive identification". These different uses of projective identification affect couples' capacities to provide what Bion called "containment". In disturbed couples, partners serve as what Meltzer termed "claustrums" whereby projections are not contained, but imprisoned or entombed in the other. Applying the concept of claustrum helps illuminate common feelings these couples express, such as feeling suffocated, stifled, trapped, held hostage, or feeling as if the relationship is killing them. Finally, this paper presents treatment challenges in working with more disturbed couples.

Poverty is one continuing social issue which is hard to solve. Dealing with this problem, Islam has already had the alternative solution that is tithe (Zakat). Zakat is implemented to decrease economy imbalanced appeared in the society. While in fact, not all the Moslem pay Zakat. There are five factors as the reason why Moslem didn’t do that. First, some Muzakki wants to deliver his zakat directly.Seconde, not all Muzakki know how much Zakat must be paid. The other factors are Limited information about Mustahik home, limited time that Muzakki have to deliver his Zakat directly and the easiness to report Mustahik data. Dealing with those factors, it is required to have an information system which can make Muzakki meets Mustahik. In this research, information system application used Extreme Programming (XP) development method. XP method is required to program a system which will be made by accomodating the users’ needs and expectations.

Rhetoric has always been torn between the rhetoric of figures and the rhetoric of conflicts or arguments, as if rhetoric were exclusively one or the other. This is a false dilemma. Both types of rhetoric hinge on the same structure. A common formula is provided in Chapter 3 which unifies rhetoric stricto sensu and rhetoric as argumentation as two distinct but related strategies adopted according to the level of problematicity of the questions at stake, thereby giving unity to the field called “Rhetoric.” Highly problematic questions require arguments to justify their answers; non-divisive ones can be treated rhetorically through their answers as if they were self-evident. Another classic problem is how to understand the difference between logic and rhetoric. The difference between the two is due to the presence of questions explicitly answered in the premises in logic and only suggested (or remaining indeterminate) in rhetoric.

AbstractGaahmg has ergative traces in a predominately nominative-accusative system. Clauses with object focus demonstrate ergative case marking on postverbal noun and pronoun agents, and an ergative morpheme is also bound to verbs. Other evidence for ergativity is that the ergative morpheme is morphologically and syntactically distinct from the passive morpheme. Ergative morphemes and constructions in Gaahmg are similar to those of other Nilo-Saharan languages, including Luwo, Päri, and Shilluk. The Gaahmg antipassive also resembles that of other Nilo-Saharan languages. Yet, unlike other languages with ergativity and antipassives, Gaahmg readily combines the antipassive with ergative, passive, and causative morphemes in the same verb form. The Gaahmg antipassive occurs in nominative-accusative structures, as well as in object-focus clauses with ergative-absolutive structures. Further, the antipassive co-occurs with the passive, as if both the nominative-accusative and ergative-absolutive structures are simultaneously present in the same clause, and the language is currently shifting from one structure to the other.

Combining clusters of magnetic materials with a matrix of other magnetic materials is very interesting for basic research because new, possibly technologically applicable magnetic properties or magnetization reversal processes may be found. Here we report on different arrays combining iron and nickel, for example, by surrounding circular nanodots of one material with a matrix of the other or by combining iron and nickel nanodots in air. Micromagnetic simulations were performed using the OOMMF (Object Oriented MicroMagnetic Framework). Our results show that magnetization reversal processes are strongly influenced by neighboring nanodots and the magnetic matrix by which the nanodots are surrounded, respectively, which becomes macroscopically visible by several steps along the slopes of the hysteresis loops. Such material combinations allow for preparing quaternary memory systems, and are thus highly relevant for applications in data storage and processing.

Abstract When do politicians lie? A politician who admits to wrongdoing will likely suffer some loss of popularity, but probably not as great as if he denied wrong doing and was subsequently discovered to have lied. This simple observation has a number of implications. For example, a politician in a marginal seat may have little choice but to risk lying as admitting will lose him too much popularity to survive. On the other hand, a politician in a relatively safe seat might survive the loss from admitting, but not from lying and being caught. Therefore we might predict the likelihood that a politician admits to a scandal to be positively related (over some range at least) to the security of his seat. This paper tests this prediction, and some others, with data from House bank scandal of 1991-92.

To look at the usefulness of a neutral task in studying 2-person interactions, to ascertain some behavioral correlates of experimentally manipulated attraction, to investigate the generality of the similarity-attraction hypothesis, and to examine the behavioral relevance of scores on a commonly used paper-and-pencil attraction scale, Ss interacted with confederates posing as Ss. Each S was given the impression that C had similar or dissimilar attitudes and twice S performed an incomplete sentences task administered by C. On one set of trials, S was instructed to act as if he liked C, and on the other set as if he did not. Measured behaviors were eye contact, interview length, number of words used, smiles, and both S's and C's response latencies. In the high-attraction role-playing condition, more smiles and a higher percentage of eye contact occurred than in the low-attraction role-playing condition. But no differences in the other behaviors were noted, only very mild support was obtained for the similarity-attraction hypothesis, and none of the measures were related to scores on the paper-and-pencil index of interpersonal attraction.

The article’s aim is to measure the potential of Derrida’s work for a philosophy of technique. It shows why Derrida does not present a positive philosophy of technology but rather describes technique as a quasi-technique, as if a technique. The article inquires into the potential of such a quasi-technique for a contemporary philosophy of technology: it is suggested that it can function as a salutary “deconstruction” of mainstream philosophy of technology (that “knows” the “essence of technology”) because it shows how to think technique in the absence of essence and as the absence of essence. The article begins with a survey of the machines that figure in Derrida’s texts. It then examines three propositions concerning technology in Derrida’s work: Derrida thinks technology as a metaphor of writing and not the other way round. Derrida thinks technique as prosthesis, firstly of memory, then more generally of life. Derrida’s quasi-technique relies on his peculiar conception of the incorporal materiality of technique.

In the spectrum formed by a grating the red is more deviated than the blue, while in that formed by a prism, which does not exhibit anomalous dispersion in the visible spectrum, the reverse is the case. If, then, white light is passed first through a grating and then through a prism, the nature of the spectrum produced will depend on the relative dispersions of the grating and prism. If throughout the spectrum the dispersion of the prism is less than that of the grating, the sequence of colours will be the same as that in the spectrum due to the grating alone, red being more deviated than blue. If, on the other hand, the dispersion of the prism is throughout the spectrum greater than that of the grating, the sequence of colours will be reversed. On account of the rapid increase in the dispersion of glass near the blue end of the spectrum, it may, however, be possible that the dispersion of the prism exceeds that of the grating in the blue while in the red the reverse is the case. Under these conditions both red and blue will be more deviated than some intermediate colour for which the dispersions of the grating and prism are equal. The spectrum will thus have a sharp edge of this colour at the end of minimum deviation, while in the direction of greater deviation it will at each point consist of two superimposed colours. It is as if an ordinary white light spectrum was folded back on itself about the sharp edge.
