Summary. When participants have to shift between four tasks that result from a factorial combination of the task dimensions judgment (numerical vs. spatial) and mapping (compatible vs. incompatible), a characteristic profile of shift costs can be observed that is suggestive of a hierarchical switching mechanism that operates upon a dimensionally ordered task representation, with judgment on the top and the response on the bottom of the task hierarchy ( Kleinsorge & Heuer, 1999 ). This switching mechanism results in unintentional shifts on lower levels of the task hierarchy whenever a shift on a higher level has to be performed, leading to non-shift costs on the lower levels. We investigated whether this profile depends on the way in which the individual task dimensions are cued. When the cues for the task dimensions were exchanged, the basic pattern of shift costs was replicated with only minor modifications. This indicates that the postulated hierarchical switching mechanism operates independently of the specifics of task cueing.

‘The art of free society’, A.N. Whitehead declares in his essay on symbolism, is fundamentally dual. It consists of both ‘maintenance of the symbolic code’ and a ‘fearlessness of [its] revision’. This tension, on the surface paradoxical, is what Whitehead believes will prevent social decay, anarchy, or ‘the slow atrophy of a life stifled by useless shadows’. Bearing in mind Whitehead’s own thoughts on the nature of symbolism, this chapter argues that the figure of the creature has been underappreciated in his work as a symbol. It endeavors to examine and contextualize the symbolic potency of creatureliness in Whitehead’s work, with particular attention directed toward the way the creature helps him to both maintain and revise an older symbolic code. In Process and Reality, ‘creature’ serves as Whitehead’s alternate name for the ‘individual fact’ or the ‘actual entity’—including (perhaps scandalously, for his more orthodox readers) the figure of God. What was Whitehead’s strategic motivation for deploying this superfluous title for an already-named category? In this chapter, it is suggested that his motivation was primarily poetic (Whitehead held the British romantic tradition in some reverence) and so, in this sense, always and already aware of its rich symbolic potency.

The attention sustainability and its impact of social status in the class are current issues concerning the field of education are the reasons for delay in assimilating the learning material and early school dropout. Behind both of those problems stand psychological causes such as low attention sustainability, poor communication skills and lack of positive environment. The presented article aims to prove that sustainability of attention directly influences the social status of students in the class, and hence their overall development and the way they feel in the group. Making efforts to increase students’ attention sustainability could lead to an increase in the social status of the student and hence the creation of a favorable and positive environment for the overall development of the individual.

AbstractA common marker for inhibition processes in task switching are n − 2 repetition costs. The present study aimed at elucidating effects of no-go trials on n − 2 repetition costs. In contrast to the previous studies, no-go trials were associated with only one of the three tasks in the present two experiments. High n − 2 repetition costs occurred if the no-go task had to be executed in trial n − 2, irrespective of whether a response had to be withheld or not. In contrast, no n − 2 repetition costs were visible if the other two tasks were relevant in n − 2. Whereas this n − 2 effect was unaffected by whether participants could reliably exclude a no-go trial or not, effects of no-gos in trial n were determined by this knowledge. The results differ from effects of no-go trials that are not bound to a specific task. It is assumed that the present no-go variation exerted its effect not on the response level, but on the level of task sets, resulting in enhanced salience of the no-go task that leads to higher activation and, as a consequence, to stronger inhibition. The dissociation of the effects on no-gos in trials n − 2 and n as a function of foreknowledge suggests that the balance between activation and inhibition is shifted not only for single trials and tasks, but for the whole task space.

[In the writings of Orthodox theologian Paul Evdokimov (1901–1970), Western theology can find new resources regarding the relationship between gender and moral development. The author presents Evdokimov's unique theological anthropology in the context of both the complicated question of gender, as well as the effects that gender has on the way women and men act. While the goal of the Christian life for both is the transformation of the individual through asceticism, the role each plays in the salvation of the world differs markedly.]

AbstractDespite advances in women’s equality, and perhaps as a result of it, sexist humor is prevalent in society. Research on this topic has lacked realism in the way the humor is conveyed to participants, and has not examined perceptions of both men and women who use sexist humor. We embedded jokes in printed Facebook profiles to present sexist humor to participants. We manipulated the gender of the individual in the profile (man or woman), and the type of joke presented (anti-men, anti-women, neutral) in a 2×3 between-groups design. We found that both men and women rated anti-women jokes as more sexist than neutral humor, and women also rated anti-men jokes as sexist. We also found that men who displayed anti-women humor were perceived less positively than men displaying anti-men humor, or women displaying either type of humor. These findings suggest that there may be different gender norms in place for joke tellers regarding who is an acceptable target of sexist humor.

In social work practice, keeping records of encounters with clients is a routinized practice for documenting cases. This paper focuses on the specific task of obtaining the prospective clients’ correct address for filling in a standardized personal report form. My analysis focuses in the way both the client(s) and the social worker cooperatively orient to the practice of writing addresses, showing how this apparently simple task is multimodally implemented within interaction, and how it can generate some complications and expansions. A special focus will be devoted to difficulties encountered by clients to give their address in an adequate way, as well as to the transformation of this activity from an individual to a collective task.

In the field of Deaf Geographies, one neglected area is that of the individual deaf body and how individual deaf bodies can produce deaf space in isolation from one another. Much of the work published in the field talks about collectively or socially produced deaf spaces through interaction between two or more deaf people. However, with deaf children increasingly being educated in mainstream schools with individual provisions, and the old social networks and institutions of deaf communities coming under threat by the closure of deaf clubs and changing work practices, more research on the way in which individuals can produce their own deaf spaces and navigate those spaces is needed. In this paper, I outline two possible theoretical approaches, that of Lefebvre’s productive gestures to produce social space, and Bourdieu’s habitus, capital and hexis. I suggest that these theories can be productively utilised to better understand the individual basis of the production of deaf spaces.

Achieving high result-accuracy in approximate computing (AC) based real-time applications without violating power constraints of the underlying hardware is a challenging problem. Execution of such AC real-time tasks can be divided into the execution of the mandatory part to obtain a result of acceptable quality, followed by a partial/complete execution of the optional part to improve accuracy of the initially obtained result within the given time-limit. However, enhancing result-accuracy at the cost of increased execution length might lead to deadline violations with higher energy usage. We propose Prepare , a novel hybrid offline-online approximate real-time task-scheduling approach, that first schedules AC-based tasks and determines operational processing speeds for each individual task constrained by system-wide power limit, deadline, and task-dependency. At runtime, by employing fine-grained DVFS, the energy-adaptive processing speed governing mechanism of Prepare reduces processing speed during each last level cache miss induced stall and scales up the processing speed once the stall finishes to a higher value than the predetermined one. To ensure on-chip thermal safety, this higher processing speed is maintained only for a short time-span after each stall, however, this reduces execution times of the individual task and generates slacks. Prepare exploits the slacks either to enhance result-accuracy of the tasks, or to improve thermal and energy efficiency of the underlying hardware, or both. With a 70 - 80% workload, Prepare offers 75% result-accuracy with its constrained scheduling, which is enhanced by 5.3% for our benchmark based evaluation of the online energy-adaptive mechanism on a 4-core based homogeneous chip multi-processor, while meeting the deadline constraint. Overall, while maintaining runtime thermal safety, Prepare reduces peak temperature by up to 8.6 °C for our baseline system. Our empirical evaluation shows that constrained scheduling of Prepare outperforms a state-of-the-art scheduling policy, whereas our runtime energy-adaptive mechanism surpasses two current DVFS based thermal management techniques.

The article deals with the influence of the archetype of the way on the formation of the personality in the novel Paper Towns by John Green. The purpose of this article is to determine the originality of the image of an American teenager and to identify the influence of the archetype of the way on the formation of the personality, as well as to consider the archetype of the way as a real path of the character in the novel Paper Towns by John Green, taking into account the individual author’s interpretation. This object of research has been chosen because through it one can comprehend the specifics of the psychology of a teenager and define the artistic features that distinguish the author’s stylistics and worldview. The comprehensive research methodology has been used in the work: the synthesis of the comparative historical method, holistic analysis, elements of mythopoetic and hermeneutic methods. In the novel Paper Towns by John Green mythopoetic consciousness presupposes ontological ambivalent intentions in the archetype of the child / teenager (good and evil children). The metaphorical extension of the archetype of the child / teenager has been revealed in this article. All the images of teenagers are given in the development, on the way to growing up. The originality of the archetype of the way here lies in the fact that it merges with the concepts of Space and Chaos, confirming the idea of the unity of mankind. The metaphors themselves are also peculiar, associated with the archetype of the way: inanimate strings, gradually turning into living blades of grass, intertwined with roots with all that exists. During the search for Margo, Quentin grows up significantly, becomes more tolerant to their friends, and he learns to take responsibility for him. The image of Margo is the image of a rebel against any lack of freedom that it is inevitable in the “golden cage”. It is also revealed how Quentin is influenced by the new world opened during his trips, and his personal environment: for example, Radar opens his eyes to the fact that he does not need to demand too much from others. Both Margo is changed (from a “paper” girl – to a real one) and Ben and Radar are changed (false interests go into the background; everyone learns to expose himself to risks and troubles for the sake of friendship and human salvation). Ben and Radar are also shown in the development, in a short time they learn to understand each other and distinguish false values from true ones. These changes occur with all the teenagers, regardless of their skin color and nationality, and such an interpretation of the insignificance of formal differences is also a new word of the author.

The paper analyses the protection granted under Article 8 of the European Convention of Human Rights for different immigration cases. The way the European Court of Human Rights determines compliance with Article 8 for settled migrants differs from the way the Court determines compliance for foreign nationals seeking entry or requesting to regularize their irregular migration status. The paper argues that the European Court of Human Rights application of different principles when determining a States’ positive and negative obligations is contradicting its own case law. It also argues that the absence of justification grounds for the refusal of foreign nationals who are seeking entry lacks legitimacy. By treating all immigration cases under Article 8(2) the paper suggests that the differentiation between cases should be based on how a refusal of entry or an expulsion would impact on the family life. The paper also suggests that more consideration should be given towards the insiders interests when balancing the individual rights against the state's interests. These changes would lead to a more consistent and fair case law and generate a more convergent practice by the states which will increase the precedent value of the Court's judgements.
