Crucial Ingredient

<p>The dynamic composition of components is an emerging concept that aims to allow a new application to be constructed based on a user’s request. Three main ingredients must be used to achieve the dynamic composition of components: goal, scenario, and context-awareness. These three ingredients must be completed by artificial intelligence (AI) techniques that help process discovery and storage. This paper presents framework architecture for the dynamic composition of components that can extract expressed goals, deduce implicit ones using AI. The goal will be combined with pertinent contextual data, to compose the relevant components that meet the real requirements of the user. The core element of our proposed architecture is the composer component that (i) negotiate user goal, (ii) load the associated scenarios and choose the most suitable one based on user goal and profile, (iii) get binding information of scenario’s actions, (iv) compose the loaded actions, and (v) store the new component as a tree of actions enabled by contextual or process constraint. In our e-learning proven of concept, we consider five components: composer component, reader component, formatter component, matcher component, and executor component. These five components stipulate that a course is the combination of existing/scrapped chapters that have been adapted to a user profile in terms of language, level of difficulty, and prerequisite. The founding result shows that AI is not only an element that enhances system performance in terms of timing response but a crucial ingredient that guides the dynamic composition of components.</p><div style="display: none;"> </div>

High Scalability

Knowledge extraction, data mining, e-learning or web applications platforms use heterogeneous and distributed data. The proliferation of these multifaceted platforms faces many challenges such as high scalability, the coexistence of complex similarity metrics, and the requirement of data quality evaluation. In this study, an extended complete formal taxonomy and some algorithms that utilize in achieving the detection and correction of contextual data quality anomalies were developed and implemented on structured data. Our methods were effective in detecting and correcting more data anomalies than existing taxonomy techniques, and also highlighted the demerit of Support Vector Machine (SVM). These proposed techniques, therefore, will be of relevance in detection and correction of errors in large contextual data (Big data).

Central Claim

AbstractFraming effects occur when people respond differently to the same information, just because it is conveyed in different words. For example, in the classic ‘Disease Problem’ introduced by Amos Tversky and Daniel Kahneman, people’s choices between alternative interventions depend on whether these are described positively, in terms of the number of people who will be saved, or negatively in terms of the corresponding number who will die. In this paper, I discuss an account of framing effects based on ‘fuzzy-trace theory’. The central claim of this account is that people represent the numbers in framing problems in a ‘gist-like’ way, as ‘some’; and that this creates a categorical contrast between ‘some’ people being saved (or dying) and ‘no’ people being saved (or dying). I argue that fuzzy-trace theory’s gist-like representation, ‘some’, must have the semantics of ‘some and possibly all’, not ‘some but not all’. I show how this commits fuzzy-trace theory to a modest version of a rival ‘lower bounding hypothesis’, according to which lower-bounded interpretations of quantities contribute to framing effects by rendering the alternative descriptions extensionally inequivalent. As a result, fuzzy-trace theory is incoherent as it stands. Making sense of it requires dropping, or refining, the claim that decision-makers perceive alternatively framed options as extensionally equivalent; and the related claim that framing effects are irrational. I end by suggesting that, whereas the modest lower bounding hypothesis is well supported, there is currently less evidence for the core element of the fuzzy trace account.

Two Sides

TFIIH is organized into a seven-subunit core associated with a three-subunit Cdk-activating kinase (CAK) module. TFIIH has roles in both transcription initiation and DNA repair. During the last 15 years, several studies have been conducted to identify the composition of the TFIIH complex involved in DNA repair. Recently, a new technique combining chromatin immunoprecipitation and western blotting resolved the hidden nature of the TFIIH complex participating in DNA repair. Following the recruitment of TFIIH to the damaged site, the CAK module is released from the core TFIIH, and the core subsequently associates with DNA repair factors. The release of the CAK is specifically driven by the recruitment of the DNA repair factor XPA and is required to promote the incision/excision of the damaged DNA. Once the DNA lesions have been repaired, the CAK module returns to the core TFIIH on the chromatin, together with the release of the repair factors. These data highlight the dynamic composition of a fundamental cellular factor that adapts its subunit composition to the cell needs.

Islamic Values

An Islamic system of governance is an ideal system, which is a tantalising objective for many Muslims but often times not achieved in practice. Countries may call themselves ‘Islamic’ but the core element of Islamicity, that of values such as compassion, equity and justice may not have breached the consciousness of their leaders and citizens. Sometimes it is individuals who act as the catalyst for sparking action. For a Muslim, it is his īmān that serves to light his conscience, and guiding him the dispensation of his everyday tasks within his organisation. This individualised īmān may at times serve as a small but critical factor tilting the different organisational functions of government towards integrations under an Islamic system of governance. This paper recounts the challenges of a Muslim engaging in legal issues in a non-Islamic context, seeking to help enable his organisation to undertake the role of incorporating non-Islamic law with Islamic values.

Blue Hole

The articles in this Forum are revised versions of papers presented in a roundtable session of the XXII International Congress of Historical Sciences, which was held in Jinan, China, during August 2015. In line with the roundtable format deployed by the congress, a broad proposition was introduced in the opening paper, followed by four responses delivered by experts in the field and a plenary discussion of the issues raised by the speakers. In this session, the proponent, Ingo Heidbrink, discussed the development of maritime history as a historical sub-discipline in relation to the emergence of world (and global) history. Particular attention was afforded to the comparative growth rates of these cognate sub-disciplines, and to the reasons why maritime history has expanded relatively slowly, leading to the emergence of a ‘blue hole’ in our knowledge and understanding of the past. The four respondents then addressed the issues raised by Heidbrink from their own disciplinary and regional perspectives. As Heidbrink’s ‘Concluding Remarks’ indicate, all participants agreed that, in itself, the allocation of a session to this subject on the core programme of the congress was a significant recognition that maritime history is a historical sub-discipline that is of relevance to the wider global community of historians, and not just those who are interested in the interaction of humans and the oceans.

The dynamic composition of components is an emerging concept that aims to allow a new application to be constructed based on a user’s request. This is achieved by dynamically composing and assembling disturbed components with home ones. This paper presents a framework architecture for the dynamic composition of components that can extract pertinent contextual data and combine them with explicit/implicit intent, in order to compose the relevant components to meet the real requirements of the user. The proposed architecture includes a user feedback system that is appropriate for the use context in terms of the user profile and technical/domain knowledge. Our platform can consult the end user in order to resolve eventual composition ambiguities. The dynamic aspect of our proposition involves (i) the detection of environmental changes in response to dynamic triggers; (ii) interactive adaptation to internal changes and external stimuli; (iii) determination of the real intent of the end user; and (iv) dynamic generation of different composition plans and selection of the most appropriate option, based on context data and user intent.

Logistics Planning

Logistics problems are gradually becoming more complex and a better understanding of logistics management as a subject is a key to deal with the new challenges. A core element of logistics management is logistics planning, which substitutes for low customer service levels, high waste, and the use of buffers and slacks in the execution of logistic activities. Furthermore, the availability of information and problem-solving capabilities are established as the core parts of logistics planning. Based on this, in this paper, a conceptual model for the management of logistics planning is proposed and discussed. In this regard, the model is built on ideas from microeconomics.
