Adaptation Processes

Reusing of software entities, such as components or services, to develop software systems has matured in recent years. However, it has not become standard practice yet, since using pre-existing software requires the selection, composition, adaptation, and evolution of prefabricated software parts. Recent research approaches have independently tackled the discovery, composition, or adaptation processes. On the one hand, the discovery process aims at discovering the most suitable services for a request. On the other hand, the adaptation process solves, as automatically as possible, mismatch cases which may be given at the different interoperability levels among interfaces by generating a mediating adaptor based on an adaptation contract. In this chapter, the authors present the DAMASCo framework, which focuses on composing services in mobile and pervasive systems accessed through their public interfaces, by means of context-aware discovery and adaptation. DAMASCo has been implemented and evaluated on several examples.

Abstract Many compelling examples have recently been provided in which people can achieve impressive epistemic success, e.g. draw highly accurate inferences, by using simple heuristics and very little information. This is possible by taking advantage of the features of the environment. The examples suggest an easy and appealing naturalization of rationality: on the one hand, people clearly can apply simple heuristics, and on the other hand, they intuitively ought do so when this brings them high accuracy at little cost.. The ‘ought-can’ principle is satisfied, and rationality is meaningfully normative. We show, however, that this naturalization program is endangered by a computational wrinkle in the adaptation process taken to be responsible for this heuristics-based (‘ecological’) rationality: for the adaptation process to guarantee even minimal rationality, it requires astronomical computational resources, making the problem intractable. We consider various plausible auxiliary assumptions in attempt to remove this obstacle, and show that they do not succeed; intractability is a robust property of adaptation. We discuss the implications of our findings for the project of naturalizing rationality.

AbstractNew generations of distributed systems are opening novel perspectives for logic programming (LP): On the one hand, service-oriented architectures represent nowadays the standard approach for distributed systems engineering; on the other hand, pervasive systems mandate for situated intelligence. In this paper, we introduce the notion ofLogic Programming as a Service(LPaaS) as a means to address the needs of pervasive intelligent systems through logic engines exploited as a distributed service. First, we define the abstract architectural model by re-interpreting classical LP notions in the new context; then we elaborate on the nature of LP interpreted as a service by describing the basic LPaaS interface. Finally, we show how LPaaS works in practice by discussing its implementation in terms of distributed tuProlog engines, accounting for basic issues such as interoperability and configurability.

In the article is presented a result of researching the manifestations of social and ethnic identities in the process of adaptation of Ukrainian emigrants who live abroad (28 countries in general).Emigrants have a high level of social identity, and also high levels membership satisfaction, thanks to being a member of their reference group; self-understanding and self-development, grade of belonging and the favor of informal relationships. Middle levels have the scales of in-group grade and cohesion. The low index has been revealed according to the intergroup relationships scale.Social identity levels of emigrants with different duration of living abroad are revealed only according to the intergroup competition.The results show the long emigrant adaptation to the new social environment until they reach the stage of activity, when, on the one hand, they feel like they are in their element, but on the other hand - they cannot forget that it is a different environment and the adaptation process has not been finished yet.

The article elaborates on ways of English loanwords integration into Ukrainian, with comparison to the situation in German and Serbian. The subject matter of research includes processes of adaptation in phonetics and grammar of the above-mentioned languages. The main intralinguistic factor that influences adaptation process is disparity of phonetic and grammar level configuration of languages in contacts. English has an affluent system of vowels that causes necessity of simplification of a phonetic form of English borrowings in other languages. The major factor of phonetic adaptation is an existing tradition of conveying sounds in loanwords in a certain way. However, nowadays transcription also plays a significant role in phonetic adaptation, i.e. integration of loanwords is based on their pronunciation rather than spelling. Uncertainty of patterns for conveying sounds of foreign languages in loanwords leads to variability of phonetic form of English loanwords at the initial stage of their functioning in the recipient language. Grammar adaptation involves adjusting of loanwords to the recipient language. Its course depends on morphological type of language and affinity. The research has revealed main patterns how English loanwords obtain the category of gender, which is absent in English. These patterns are based on both formal and semantic factors. Moreover, the author considers the ways of pluralia tantum nouns integration into the system of the recipient language. The analysis has shown that there is a typological difference between borrowing process on the one hand in Slavic languages and on the other hand in German, i.e. Slavic languages, unlike German, have obligatory derivational stage for verbs and adjective adaptation, which makes process of borrowing more complicated in Slavic languages.

This article focuses on aspects of belonging the producers of reality TV programmes address in the staging of emotions. Based on interview statements by 12 experts from the field of national and international reality TV format production, we argue as follows: on the one hand, producers in reality TV shows address belonging as a perceived cultural proximity to trans-local meta-narratives of a longing for change, romantic love, competition and victory. The producers associate these trans-local meta-narratives with allegedly universal emotions. On the other hand, the producers address belonging as a perceived cultural proximity to local cultural discourses on beauty ideals and combine these with a specific local cultural performance of emotions. The results show that an emotional repertoire is developed and negotiated in the adaptation process of trans-local formats. It refers to universalistic understanding of emotional display and negotiates specific “feeling rules” accordingly.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

SummaryThe prognosis of patients with acute myeloid leukaemia (AML) has improved considerably by introduction of aggressive consolidation chemotherapy and haematopoietic stem cell transplantation (SCT). Nevertheless, only 20-30% of patients with AML achieve long-term diseasefree survival after SCT. The most common cause of treatment failure is relapse. Additionally, mortality rates are significantly increased by therapy-related causes such as toxicity of chemotherapy and complications of SCT. Including radioimmunotherapies in the treatment of AML and myelodyplastic syndrome (MDS) allows for the achievement of a pronounced antileukaemic effect for the reduction of relapse rates on the one hand. On the other hand, no increase of acute toxicity and later complications should be induced. These effects are important for the primary reduction of tumour cells as well as for the myeloablative conditioning before SCT.This paper provides a systematic and critical review of the currently used radionuclides and immunoconjugates for the treatment of AML and MDS and summarizes the literature on primary tumour cell reductive radioimmunotherapies on the one hand and conditioning radioimmunotherapies before SCT on the other hand.

In recent years, political and social conditions have changed dramatically. Many analyses help to capture these dynamics. However, they produce political pessimism: on the one hand there is the image of regression and on the other, a direct link is made between socio-economic decline and the rise of the far-right. To counter these aspects, this article argues that current political events are to be understood less as ‘regression’ but rather as a moment of movement and the return of deep political struggles. Referring to Jacques Ranciere’s political thought, the current conditions can be captured as the ‘end of post-democracy’. This approach changes the perspective on current social dynamics in a productive way. It allows for an emphasis on movement and the recognition of the windows of opportunity for emancipatory struggles.
