In this paper, we propose a graph-transformational approach to swarm computation that is flexible enough to cover various existing notions of swarms and swarm computation, and it provides a mathematical basis for the analysis of swarms with respect to their correct behavior and efficiency. A graph transformational swarm consists of members of some kinds. They are modeled by graph transformation units providing rules and control conditions to specify the capability of members and kinds. The swarm members act on an environment—represented by a graph—by applying their rules in parallel. Moreover, a swarm has a cooperation condition to coordinate the simultaneous actions of the swarm members and two graph class expressions to specify the initial environments on one hand and to fix the goal on the other hand. Semantically, a swarm runs from an initial environment to one that fulfills the goal by a sequence of simultaneous actions of all its members. As main results, we show that cellular automata and particle swarms can be simulated by graph-transformational swarms. Moreover, we give an illustrative example of a simple ant colony the ants of which forage for food choosing their tracks randomly based on pheromone trails.

In this article I review a series of artworks, artistic performances and installations that deal with the topic of surveillance. My aim is twofold. On the one hand, I want to look comparatively at how different artists interrogate, question, quote, or critise surveillance society. On the other hand, I take these artistic actions as themselves symptomatic of the ways in which surveillance interrogates contemporary society. In other words, my claim is that surveillance does not simply produce substantive social control and social triage, it also contributes to the formation of an ideoscape and a collective imagery about what security, insecurity, and control are ultimately about, as well as the landscape of moods a surveillance society like ours expresses.

Focusing on Early and Middle Byzantine (fourth-to-twelfth-century) objects, images, and texts, this essay explores the tension between, on the one hand, efforts of the Byzantine church and state to discourage and control bodily adornment and modification and, on the other hand, the extensive evidence of widespread and immoderate engagement with these practices. The enhancement and manipulation of Byzantine bodies is considered as both a real and a metaphoric phenomenon. Evidence culled from secular and sacred, written and material sources demonstrates the importance of bodily adornment and modification to our understanding of Byzantine material and visual culture.

The individual ways of the stutter correction group participants are considered in the article. We see this situation as difficult and even antinomical for participant because it requires the his partial rejection of self-control and a trust in handing over his consciousness to the group leader. We assume that this aspect of communication is expressed only stronger in the situation considered here, but is presented in all kinds of communication. On the other hand, not only psychology, but also our culture lacks in adequate measures for understanding and control of such a processes in the communication. Our analysis of participant’s interviews shows that the participant’s way in the correctional process depends on ones attitudes towards the problem of handing control over one’s condition to the group leader.

This chapter examines the historical and ideological aspects of women's dining. The scholarship reveals that, during early periods, women sat to dine while men reclined; whereas “now,” women too recline to dine, just as men do—their posture must therefore have changed at some point. On the other hand, by linking the alleged shift in women's posture to overall moral decline, these studies reveal that the distinction between the two postures has ideological implications. That is, dining posture is a locus where practice, gender, and ethics intersect. The chapter suggests that the seated posture functioned pragmatically, placing women under male scrutiny and control. Moreover, whatever the vagaries of actual social practice, the seated posture for women remained at all times the “strict protocol,” even in the Imperial period.

Representing players' strategies in game theory has a direct impact on the players' performance. The state of art shows that automata are one of the primary techniques used for representing players' strategies and behaviors. In this paper, the author will identify different types of automata and assess their utilization in the field of game theory. Is has been found that finite automata, adaptive automata, and cellular automata are widely adopted in game theory. The utilization of finite automata is found to be limited to represent simpler players' behavior. On the other hand, adaptive automata and cellular automata are intensively applied in complex environments, where the number of interacted players is large and therefore, representing complex behaviors are needed.

A business-owning family and a soon-to-be-wed couple often face two mutually exclusive goals that seem impossible to reconcile. On the one hand, a couple considering marriage wants to believe that love alone will keep them together. On the other hand, statistics today say there is a good chance the relationship will not last. A prenuptial agreement provides the protection an individual or the family may want against a possible divorce, but the process by which the document is introduced and negotiated can deplete the relationship of intimacy. How can a woman from a wealthy business-owning family express and reinforce the emotional commitment and trust she has for her partner while presenting a prenuptial agreement] How can a son administer a prenuptial agreement to his fiancee without controlling the process or outcome of his spouse's financial welfare] How can a family require a prenuptial agreement without jeopardizing their future relationship with the newlyweds] In the following interview, Judy Barber, a consultant and licensed marriage and family counselor specializing in the psychology of money, outlines several recommendations for families and couples who are considering a prenuptial agreement.

SUMMARYAggregation chimaeras were made from embryos of C57BL/6 and BALB/c mice. Chimaeric and control females were mated with ICR males at 8 weeks of age and their litter sizes were evaluated over a 5-month period after the first mating. Progeny tests showed that 18 of 27 chimaeras produced oocytes of both genotypes. The mean litter sizes of C57BL/6, BALB/c and their F1 crosses (C57BL/6 × BALB/c and BALB/c × C57BL/6) were 8·14, 9·36, 13·38 and 13·40, respectively. The mean for chimaeras was 11·54 and chimaeric heterosis was evident, but it was not as much as heterosis in the F1 When the chimaeras were classified into the mixed and single-genotype progeny chimaeras, chimaeric heterosis was observed only in the mixed-progeny chimaeras. Quantitative GPI analyses in ten organs showed that the degree of chimaerism in the mixed-genotype progeny chimaeras was higher than that in most of the single-genotype progeny chimaeras and that the degree of chimaerism in the ovaries was positively correlated with litter size in the mixed-genotype progeny chimaeras. On the other hand, such correlation was not observed in the single-genotype progeny chimaeras.

This chapter discusses the novels of Chariton and Xenophon of Ephesus. Both are engaged with central concerns of the Second Sophistic, in particular that of elite Greek identity. Chariton’s novel (composed in the second century and connected with the sophist Dionysius of Miletus) demonstrates the same empathetic recreation of the classical past as sophistic declamation, and defines the Greekness of his protagonists in antithesis to a Persia configured to enable the exploration of the contemporary accommodation of the Greek elite to Rome. In his vision, paideia is a central constituent of Hellenic identity, enacted through an important third character, who represents an older erotic paradigm in contrast to the romantic heroes. Xenophon’s novel (probably an epitome), on the other hand, uses a contemporary setting to explore the nightmare of the loss of social status and control over one’s own person.

In contrast to many investigations of cellular automata with regard to their ability to accept inputs under certain time constraints, in this paper we are studying cellular automata with regard to their ability to generate strings in real time. Structural properties such as speedup results and closure properties are investigated. On the one hand, constructions for the closure under intersection, reversal and length-preserving homomorphism are presented, whereas on the other hand the nonclosure under union, complementation and arbitrary homomorphism are obtained. Finally, decidability questions such as emptiness, finiteness, equivalence, inclusion, regularity and context-freeness are addressed.

The present study aimed at exploring the influence of a repeated exposure to the Metacognitive Awareness Listening Questionnaire (MALQ) on EFL learners’ level of metacognitive awareness. Participants of the study were forty intermediate university students who were randomly assigned to experimental (n=20) and control (n=20) groups. The experimental group completed MALQ in odd sessions (seven sessions in total) across a semester. The control group, on the other hand, completed it in the first and last sessions of the course as pre-test and post-test, respectively. Results of the study showed that the questionnaire benefited the experimental group in a statistically significant way. Also, findings of the study revealed that less-skilled participants of the experimental groups benefited from the treatment more in comparison to their more-skilled counterparts in the experimental group. Keywords: MALQ, metacognitive instruction, metacognitive awareness
