This paper provides an analysis of the main methods for sentence classification in scientific papers and evaluates the feasibility of this technique in unstructured papers in Software Engineering area, in order to automatically find the study results in this area. Tests conducted with the existing methods using unstructured Test Software papers showed results far below those reported by the authors with input sets composed by structured health papers. Therefore, there is a need for new approaches to identify results in unstructured papers. [ABSTRACT FROM PUBLISHER]

The purpose of this study was to evaluate the effectiveness of using procedural scaffoldings to enhance group discourse levels in a paper-plus-smart phone learning context. Sixty undergraduate and graduate students enrolled at a four-year university in southern Taiwan participated in this experimental study. All participants used built-in camera smart phones to learn new knowledge by scanning QR codes embedded in paper-based learning materials in this study. The researchers applied content analyses and a chi-square test to answer the research question. The findings indicated that participants in the experimental group expanded higher-order discourse levels than their counterparts in the control group. [ABSTRACT FROM PUBLISHER]

This section presents several abstracts of research about organizational communication. The progress of the past seven years of field study research on work group effectiveness was examined in the paper titled "Work Team Effectiveness Field Research: Progress and Prospects." An analysis of thirty-six empirical studies reveals that work team field research is proceeding primarily along dimensions of interdependence, autonomy, diversity and conflict. In the paper "Temporal Effects of Relational Stocks on Technology-Enabled Group Performance," the authors extend existing group development models by employing a complementary stock perspective. Results suggest more complex implications of utilizing technology than previously observed delays in relational development that accompanies technology use.

In the ever growing literature on countering the cyber threat, the so-called JDL model of data fusion, well established in the information fusion community, has been applied to characterize the inner structure of problems within cyber defence and their mutual relationship. The overarching goal is to provide contributions to comprehensive cyber situational awareness by producing timely situation pictures. Cyber situational awareness, however, is prerequisite to taking appropriate actions, i.e. for “defence”. In this review paper, we provide an overview of what has been proposed in this context by various authors and collect basic insights published in the open literature. By doing so, we wish to provide an overview of the current discussion which reflects our own apprehension and prioritization. Moreover, we stress our opinion where relevant research questions are to be expected. [ABSTRACT FROM PUBLISHER]

Information and Communications technologies (ICT) play a critical role in expanding the boundaries of the academic research activities. Where the academic researchers utilize the ICT mostly to enhance their research. Due to the increasingly powerful capabilities of smart phones technology, smart phones become one of the wide spread technologies worldwide. Thus, many studies focused on studying the acceptance of smart phones. However a lack exists in studying the acceptance of smart phones for academic researchers, although of the importance and capabilities of such technologies for the researchers. On account of the role of individual's IT knowledge plays in the technology acceptance and the impacts of willingness to learn on it, the paper integrates the knowledge with the capability of using that knowledge and the learning willingness constructs to the proposed model. Hence, this conceptual paper investigates the acceptance of smart phones by the academic researchers using technology acceptance model. And integrates the absorptive capacity construct (represent IT knowledge with the capability of using that knowledge) with self-efficacy construct (represent willingness to learn) to the model.

This paper presents a new perspective on the issue of localization and contextualization of the undergraduate software engineering curriculum in developing countries. We propose to supplement the international software engineering curriculum with the history, methods, techniques, anecdotes and experiences of the local software industries, its people, successes, failures and environment. The aim is to provide a more realistic student experience that connects international methods and processes with local examples. Thus producing graduates that are familiar with the local challenges and realities that have the capabilities to adapt and transform their acquired skills to meet the local context. This paper is based on the author's experience in teaching software engineering in a developing country and in working within that country's local software industry. [ABSTRACT FROM PUBLISHER]

Selecting the right data is an essential activity in Genomic-related Information Systems. This work aims to analyze if it is possible to select the best genomic databases from a catalog using information about papers citations related to these genomic databases. The motivation for using information about citations has to do with the fact that it is not easy to obtain proper metadata with respect to these databases. Thus, in this work, information related to papers citations is used for measuring three distinct data quality dimensions: believability, timeliness, and relevancy. Believability is evaluated through the inspection of the number of citations. The variation of the number of citations over time is useful for determining the recency of a database and it is related to the timeliness dimension. Regarding to relevancy, the keywords of papers are useful to indicate the main context of application of these databases. [ABSTRACT FROM PUBLISHER]

This research paper illuminates the different contexts elicited by seven instructors who taught fundamental engineering courses (FECs) when discussing their test usage beliefs and behaviors, beginning to address a gap in engineering education research on instructors' beliefs and behaviors and test usage in engineering courses. Tests and exams are typically heavily used in FECs like statics, dynamics, thermodynamics, and other courses in various engineering disciplines. Understanding why engineering instructors heavily rely on tests to assess student learning in these courses can be crucial in promoting the use of more diverse types of assessments, such as portfolios, concept inventory, reflection-based practices, project-based practices, and intentionality in terms of designing, administering, and interpreting tests, but research has been scarce on documenting research on this topic. Conversations around why instructors make certain course decisions typically involve the contexts these instructors are situated in, emphasizing how important contexts are in terms of influencing decision-making in these courses. Illuminating some of these contexts can be helpful to further understand instructors' beliefs and behaviors in course decision-making, specifically on heavily using tests in fundamental courses. We answered the research question: What are some of the contexts that seven instructors of fundamental engineering courses raise when discussing their test usage in their courses? The data are collected as part of a larger multi-case study that explores test usage beliefs and behaviors of seven individual engineering instructors (seven cases). Multiple sources of data and evidence triangulate to shape the case profiles for these seven instructors, with contexts emerging as an important element of these profiles. Our findings show several key contexts discussed substantially by some of these seven instructors, though not all instructors discussed the same contexts. These contexts include the influence of inertia to continue using tests, course context that includes large enrollment, and the limited autonomy for some instructors to make changes to assessment in the courses. These contexts show some intertwining characteristics to influence test usage among the participants. In addition, our findings support existing literature on inertia and course context and prominent contexts to influence course decision-making, and this paper focuses on the test usage as a form of course design decision.

This literature review aims to examine the current state of SQB theory by looking at its evolution, most used constructs, contextual coverage and propose new SQB constructs to a revised model. More specifically, this paper examines SQB research published from 2010 to 2021. While some work has been done on examining the application of SQB theory within their context, the associated SQB constructs in which this work was achieved are frequently observed. Investigating the papers from a theoretical and contextual view exposes that IS researchers have continuously used SQB, yet primary attention is on existing theories with little attention to contextual differences even though a fast-moving IT appearance is present in the field. Regardless of the context, researchers can learn lessons on SQB learned from other scholars and move beyond to further enrich the understanding of SQB with an expansion of the existing SQB literature.

Business transactions between companies are more and more executed by a flow of well-defined electronic business documents. The resulting inter-organizational business processes are often realized by concepts known from service-oriented computing. Exchanging a business document corresponds to a service call and the input/output of the service calls commonly follows a certain business document standard. However, these standards typically present the superset of all required elements used in any business context. In a specific context (in a specific industry, in a specific geopolitical region, etc.) the input/output is adjusted to this context by constraints on the generic structure. Accordingly, a specific service is always used in a specific context. It follows that it is important to define the business context of a service (in a structured format). For this purpose we have developed the Business Context Ontology model (BCOnt). In this paper we elaborate on the theoretical concepts and the underlying algorithms as well as on their implementation in practice. [ABSTRACT FROM PUBLISHER]

This paper discusses the unification of service composition based on formal specifications. The approach aims for a unified execution of service compositions that can be modeled by various specification languages covering different modeling paradigms. The unification of service composition models is realized based on formal grammars whereas the unification of service composition execution is realized based on formal queued automata. The approach introduces a classification of context-sensitive grammars for determining an optimized automaton class for the execution of service compositions. Finally, a prototype providing transformations of various modeling languages to formal grammars as well as the grammar-based execution of service compositions is presented. [ABSTRACT FROM PUBLISHER]

The advances of pervasive technology offer new standards for user comfort by adding intelligence to ubiquitous home and office appliances. With intelligence being the core of some newly constructed buildings, it is important to design a scalable, robust, context-aware architecture, which not only has enough longevity and evolving capabilities to sustain itself over the building's lifetime, but also provides enough potential for additional features to be added to the core Building Management Systems (BMS). Such features may include energy preservation system, or activity-recognition techniques. Service-Oriented Architecture (SOA) principles provide great tools that can be applied to the smart buildings design, however certain specifics of pervasive systems should be taken into account, such as high heterogeneity of available devices and capabilities. In this paper we propose an architecture for smart pervasive applications, which is based on SOA principles and is specifically designed for long-term applicability, scalability, and evolution capabilities of a BMS. We validate our proposal by implementing a smart office on the premises of the Technical University of Eindhoven and showing that it complies with the requirements of scalability and robustness, at the same time being a viable BMS.

In ubiquitous computing, context-aware service oriented systems refer to applications that use so-called contextual information to provide appropriate services or relevant information to the user or other applications to perform a specific task. An important challenge in such applications is context modeling, using ontologies to model context information and to reason about context at a semantic level has attracted a lot of interest in the research community. However, most of the presented approaches do not usually take into account any software engineering method. Therefore, employing standard approaches to formulate the development process becomes of importance. In this paper, we present an overview of the architecture for the development of context aware services based on ontologies, we also present our context modeler based on ODM (Ontology Definition Metamodel) and model transformations that allows to generate an OWL ontology representing context information.

Recently, context aware has become a popular topic in ubiquitous computing. Most context-aware research combines embedded system devices with context-aware systems to realize a ubiquitous environment. This study proposes a Daily Exercise Context Aware Ontology Model (DEOCAM) and builds a Context Aware Exercise System (CAES), which is free of space limitation. CAES is composed of three parts: Personal Exercise Management System (PEMS), Context Aware System (CAS) and Context Sharing Network Platform (CSNP). The purpose of the system is to recognize the daily activities of users, which is helpful in exercise monitoring for health management. Our experimental results show that the system is effective and feasible for daily activity contexts recognition and moving distance computation. [ABSTRACT FROM PUBLISHER]

Large number of research papers are available in the form of un-structured (text) format. Knowledge discovery in un-structured document has been recognized as promising task. These documents are typically formatted for human viewing, which varies widely from document to document. Frequent change in their formatting causes difficulties in constructing a global schema. Thus, discovery of interesting rules from it is a complex and tedious process. Recently, conditional random fields (CRFs) and hand-coded wrappers have been used to label the text (such as Title, Author Name(s), Affiliation, Email, Contact number, etc. in research papers). In this paper we propose a novel hybrid approach to infer grammar rules using alignment similarity and probabilistic context free grammar. It helps in extracting desired information from the document. [ABSTRACT FROM PUBLISHER]

In a world of open knowledge, engineering students expect from an educational program to provide practical experiences in order to get ready for the job market. Hence, design experiences, as a learning experience, are crucial for student growth, retention and engagement. Therefore, it is important to create innovative learning experiences that satisfy the achievement of these goals. In addition, such experiences need to be feasible for implementation and viable for the designer of learning - the educator. In fact, developing a design learning experience is a design task itself. Educators need to understand the student and the context in which the learning takes place in order to develop an innovative concept of a design activity. The overall purpose of introducing the context in the design endeavor is to create better solutions that suit all stakeholders but more importantly promotes inclusiveness, diversity, and equity in education by putting the student at the center of solution development. Additionally, innovation requires putting together different perspectives and knowledge. Therefore, co-designing with stakeholders is a way to spark this innovation. In this paper, we introduce the Context Canvas as a collaborative design tool to help consider the contextual factors early in the process of design learning experience development. This work in progress paper presents an example of use of the Context Canvas for redesigning a project spine course in the engineering program at our institution. [ABSTRACT FROM AUTHOR]

Service orientation has significantly facilitated the development of complex distributed systems spanning multiple organizations. However, different application areas approach such systems in domain-specific ways, focusing on particular aspects relevant only for their application types. As a result, we observe a very fragmented landscape of service-oriented systems, which does not enable collaboration across organizations. To address this concern, in this work we introduce the notion of Collaborative, Dynamic and Complex (CDC) systems and position them with respect to existing technologies. In addition, we present how CDC systems are modeled and the steps to provision and execute them. We also contribute an architecture enabling CDC Systems with full life cycle coverage that allows for leveraging service-oriented and Cloud-related technologies. [ABSTRACT FROM PUBLISHER]

The environmental impact of doing business becomes an increasingly relevant aspect for organizations, not only because of legal requirements but also because more customers care about. Most organizations, however, do not have comprehensive knowledge on how to restructure their business processes accordingly. In previous work we proposed green business process patterns that address the environmental impact explicitly as one possible solution. Beyond those patterns, we now provide a method to extract environmentally relevant patterns from existing patterns of different domains. Moreover, we present a set of such patterns related to automated business processes. The proposed approach as well as the identified patterns support stakeholders when analyzing their business processes with respect to the environmental impact and, therefore, supporting green business process reengineering.

In this paper we present the outcomes of a literature review on the interconnection of Decision Support Systems (DSS) and online social networking. Although a large number of research papers postulate, in one way or another, that Decision Support Systems and online social networking are interconnected, only a small amount of them actually elaborates on such connection. Therefore, we underwent a large bibliographic review, based on four major bibliographic indexing resources to reveal the actual interconnection of DSS and online social networking.

The decision-making process in boardrooms has a significant impact on organizational performance. In the last two decades, scientific research on the decision-making process in boardrooms has increased. This resulted in a substantial body of knowledge about boardroom factors and their relation to organizational performance. However, the effectiveness of the decision-making process in boardrooms is still mainly a black box. Amongst other things, scientific findings seem to contradict each other, which could mean additional insights are still missing. This research aims to contribute to a better understanding of this black box. This is done by providing an overview of the existing scientific literature on the relations between these factors, the circumstances, and the effectiveness of the boardroom. The study described in this paper is based on a preliminary literature research and insights from this study will be used to conduct a more in-depth structured meta-literature review. In addition to insights into the factors and characteristics that influence the decision-making process in boards and the mechanisms that influence the boards effectiveness, the most important insights for follow-up research from this study are: findings from earlier research seem contradicting, and the research area cannot be fully understood by observing it from a single- or even double lens (like boardroom characteristics, psychological factors or organizational perspective). Part of the explanations for the effectiveness of decision-making in boardrooms must be sought in variables that are difficult to observe, difficult to measure, under difficult circumstances from multiple scientific lenses and theories.

Paper-based Modified Early Warning Scorecards (MEWS) have been developed to help nursing staff detect hospital in-patient deterioration at an early stage. MEWS is based on patient vital signs where these values are transformed into a MEWS score. An electronic Modified Early Warning Scorecard (eMEWS) prototype has been designed and developed to fulfill the role of a computerized Clinical Decision Support System (CDSS) and to assist healthcare professionals in their decision making activities. A review of the existing electronic Early Warning Scorecards (eEWS) revealed they lack certain features that assist in capturing a holistic view of the patient health status for example color codes and vital sign trends. The proposed eMEWS prototype employs these features with the aim of assisting healthcare professionals to obtain a clear understanding of the patient status. A survey was conducted to evaluate the impact of paper-based MEWS and eMEWS as part of the decision making process. The advantages and disadvantages of eMEWS over the paper-based MEWS are presented.

Context-aware systems are fundamental for making the use of computing devices intuitive. These systems respond to their environments to facilitate seamless interactions between the users and their computing devices, and to make these devices less intrusive. Although it is more than a decade since context-aware systems were introduced, context is still not well understood within a context-awareness research community. Although there are numerous definitions of context, these definitions refer to context as an input or as a derivable. The majority of researchers believe any input that makes a context-aware system to accomplish its task is a context. In the contrast, there is handful of researchers who believe context is derived from more than one inputs. This paper aims to provide a clear meaning of context and consequently to resolve the differences between researchers regarding context. In particular, this paper answers the most fundamental, but yet the most avoided, question; what is context? [ABSTRACT FROM AUTHOR]

In this paper we try to analyse the current and historical application of Knowledge Management in the Portuguese Economy, particularly since the democratic revolution of 1974. We base our analysis in theories about the impacts of knowledge in countries at a micro and a macro scale. We use a three levels model related to context (namely 1) Historical background; 2) basic economic and social data: 3) broad vocational education and training (VET) systems; 4) institutional actors; 5) political context), intervention (namely 1) basic legislative documents, 2) guidelines on eligibility, 3) programs, 4) evaluation procedures) and outcomes (namely 1) stocks, investment, and outcomes; 2) price, quantity, supply, demand, equilibria; 3) needs). We base ourselves in statistical published data and other published documents. We conclude that the context changed for the better, because after 1974 the country rulers installed a regime in which knowledge was not seen like a luxury but as a basic need (see 4.1); the change in context was also helped by the adhesion to the EU, which in turn led to massive interventions supported by funds like the ESF and the Regional fund(see 4.2); as a result outcomes are finally seen, as the increase in supply and demand of knowledge and also in the income and employability of the Portuguese attests (see 4.3). These findings are important but should be complemented by a more detailed analysis, with a larger group of researchers -- at best this paper would generate a book, detailing the context, intervention and impact of KM in Portugal.

Stability is an important aspect of social network. This paper investigates pairwise stability and it's algorithm with Jackson-Wolinsky rules. By establishing abstract games of network formation with respect to path dominance, representing the path dominance of all feasible networks as a supernetwork, and using the conclusion that the path dominance core is equal to the set of pairwise stability, we give an intuitive algorithm to find pairwise stability network. In the meantime, the paper gives the set of pairwise stability network with four nodes and the algorithm. [ABSTRACT FROM PUBLISHER]

How did enterprise innovation capability convolutes with external environment in the context of economic transition? In this paper, a longitude study is operated, using the case of Sunyard, to show the rule as well as the mechanism underlying the coevolution process. On the one hand, this paper reveals how enterprise adapt to the environment to pursue resources for product innovation under multi-institutional pressure; on the other hand, this paper reveals how companies leverage innovation capability through organizational learning and then select and manage the environment. More importantly, this paper links these two aspects, and reveals the ambidexterity mechanism between selection and adaptation. Theoretically, this finding not only unique to China, but also can be found in other developing countries with under transition. [ABSTRACT FROM PUBLISHER]

Grammatical inference (GI) of context free languages (CFG) is an actively researched area of computer science. There are some algorithm, based on different approaches, to induce CFGs and we are going to test and compare the standard CFG generation methods. The goal of the comparison is to develop a more efficient CFG induction method. In order to super the testing and comparison of algorithm, a GI and TM environment, called META, was created [1]. META provides only the basic functions for common grammar processing. In this paper, we present a CFG extension of it, and show some experimental result on CFG induction with META framework.

Assessment process in one of the most important issues in the learning process and in many cases it is the process that define the sequence of the instruction because it measures the performance of the student in the educational process. In last decades the inclusion of TICs in teaching-learning process has facilitated to address the diversity of students and teachers features. Learning technologies enhance have permitted to adapt the different ways of learning and teaching that coexist in the educational context through the generation of adaptations process as well as user modeling process. This paper describes the item response theory and how it can be applied in a test scenario of an online course for the generation of adaptive assessments within a course of introduction to Object Oriented Programming from items (assessment questions), which are available in online repositories. Being a probabilistic theory the article describes the variables to consider and how to calculate the probability that a student answers correctly a specific item, which is known as the student proficiency level or theta, based on a skill test and their previous answers. In other papers write for the authors it is described the experience of working with fedora commons repositories, which are distributed across a network, in order to have enough questions to be applied properly normalized in the adaptation process. These questions are described under the Dublin Core standard. The main contributions of this project are the implementation of a probabilistic theory in the generation of adaptive assessment and use of distributed repositories that allow the reusability of items properly parameterized. A second phase of the research includes the implementation of the project (APIP) Accessible Profile Portable Item, allowing standardization of assessment items in a suitable format in the LOM.

Academic contents update and learner's capability change over time. But nowadays, academic recommendation system does not take time factors into account. There are two challenges to capture learner's preferences and learning context accurately and dynamically. First modeling academic trend and user's cognitive level transferred by time is a hard problem. And designing dynamic algorithm to improve recommendation accuracy with implicit behavior data is difficult. In this paper, we propose Dynamic Transfer Chain (DTC) to model user's preferences and academic context over time on transaction data. Based on DTC model, we present a novel algorithm Dynamic Academic Recommendation on Graph (DARG). We evaluate the effectiveness of our method using an open dataset named CiteULike, including 9170 users, 11343 papers, 194596 user-paper pairs. The evaluation metric we used is Hit Ratio. The results show that our proposed approach gives 12.873% to 33.852% improvement over the previous counterpart, including User-KNN, Item-KNN, TUser-KNN, TItem-KNN. [ABSTRACT FROM PUBLISHER]

This paper describes a novel pedestrian dead-reckoning unit (PDU) to estimate pedestrian's position. The PDU is designed for a narrow bandwidth wireless communication channel such as Bluetooth. The PDU sends not only the PDU posture, but also the abstracted sensor data such as the number of steps, basic information to estimate stride length, and the pedestrian contexts. We developed the pedestrian navigation system by using the proposed PDU. This paper shows the PDU message is compact but contains enough data to realize pedestrian navigation system using Bluetooth.

Context: Defects are an ineludible component of software, Defect Density (DD) - defined as the number of defects divided by size - is often used as a related measure of quality. Project managers and researchers alike would benefit a lot from overview DD figures from software projects, the former for decision making the latter for state-of-the-practice assessment. Objective: In this paper, we collect and aggregate DD figures published in literature, in addition we characterize DD as a function of different project factors in terms of central tendency and dispersion. The factors considered include development mode -- open vs. closed source -- , programming language, size, and age. Results: We were able to identify 19 papers reporting defect density figures concerning 109 software projects. The mean DD for the studied sample of projects is 7.47 post release defects per thousand lines of code (KLoC), the median is 4.3 with a standard deviation of 7.99. Development mode, is characterized by statistically meaningful different DD, the same for Java vs. C. Besides, in the studied sample large projects exhibited lower DD than medium and small projects. Conclusion: The study is a first step in collecting and analyzing DD figures for the purpose of characterizing one important aspect of software quality. These figures can be used both by researchers and project managers interested to evaluate their projects. Further work is needed to extend the data set and to identify predictors of defect density.

Considering the recent events in Romania, related to all sorts of instability, this paper aims at analysing and discussing the way this context influences entrepreneurship, as a key element for economic development. Based on the existing literature, we first provide an overview of the factors that influence entrepreneurship. From the perspective of our paper, we focus mostly on the contextual determinants of this phenomenon. Then, using a set of variables from Global Entrepreneurship Monitor (GEM) and the White Charter of Romanian SMEs, we analyse the entrepreneurial profile of the Romanian economy over time, in relation with its determinants. The last part of the paper discusses the policies implemented by the different Romanian governments to support entrepreneurship. It highlights the main macro policies such as, taxation, the rule of law etc. of the recent period and it shows that the mix of incoherent policy measures has created instability, confusion and chaos rather than encouraging entrepreneurial activities.

In child-robot interaction research, many studies pursue the goal to support children's language development. While research in human-human interaction suggests that changing human partners during children's language learning can reduce their recall performance of the learning content, little is known whether a change in social robots as interaction partners influence children's learning in the same way. In this paper, we present findings from a word learning study, in which we changed the robotic partner for one group of children while the other group interacted with the same robot. Contrary to work with human social partners, we found that children did not retrieve words differently when interacting with different humanoid robots as their social interaction partners.

Information and knowledge sharing mechanisms are essential for the efficient operation of cognitive wireless communication systems, complementing learning and decision making and enabling the coordination between various management entities. Information and knowledge sharing mechanisms can be defined as means for transmitting elements of information necessary to manage and realize various operations within future cognitive wireless communications systems. Information may be conveyed from network elements to terminals and vice versa, and may also be exploited for the exchange of information between terminals, so as to increase the accuracy of obtained knowledge. The paper provides an overview of related work and describes several cases of how information and knowledge sharing mechanisms can be exploited in wireless communication systems. A detailed description of the information flow between various entities is provided. An overview of potential implementation options is provided. [ABSTRACT FROM PUBLISHER]

This paper examines the best practices of innovative global Islamic micro finance governance in relations to independence, competency, confidentiality and consistency and shariah compliance issues. An innovative framework to support the Islamic microfinance institutions in discharging its duties in matters relating to Shariah was formulated within the context of the governance of Shariah Islamic microfinance among Islamic microfinance institutions in Malaysia. The governance model supports the robustness of the Grameen model. Initial investigation revealed that specific policies oriented towards the start-up and growth of innovative higher-growth enterprise was lacking. Although these institutions are able to point out a number of good examples of governance initiatives, however these examples generally not the outcome of a cohesive integrated IMFI's policy framework. Thus, there is an urgent need for the researchers to propose and develop innovative framework that examines the current best practices of global Islamic micro finance governance.

The main issue addressed in this paper is how to promote the interactions between instructor and students, and among students in class. Our approach to this issue is to provide students with micro sharing tool such as Twitter. The micro sharing tool enables the users to write in a short sentence what they think to share. Introducing it into class could encourage the students to write what they want to ask the instructor, note, and share with other students, which could accordingly play a role as back channel of the interactions in the class. This paper describes a framework for activating the interactions in class with Twitter where the students use Twitter to share what they are thinking about the lecture with the instructor and with other students. Although the instructor could obtain fruitful information for improving his/her lecture in real time from the tweets the students submit with Twitter, it would be hard to extract it in case the number of the tweets obtained becomes large. In this paper, we accordingly demonstrate a system where the tweets obtained from the students are classified according to the contents and intention so that the instructor can improve his/her lecture.

This paper introduces a retrieval system based on context rather than content. The system uses a set of vector spaces to represent the different contextual characteristics (position, time, sound environment, etc.). In this model both the current context and the items in the corpus are represented by vectors. We then use vector similarities to identify the relevant items given the context. In order to take into account the user's own perception of the context we also use learning techniques based on the user feedback. This paper also presents two applications we are currently developing, which make use of this retrieval system: a contextual adaptive User Interface selecting the right configuration profiles matching the current context as acquired by a computer, and an augmented reality application for iPhone suggesting to the user activities and places that could be of interest to him given its current environment.

The contribution of this study is a set of issues that reflect the situation at the case-study environment. Many of the identified issues relate to non-technical areas such as Organisation Control and Governance, Methodology, Process and service and people and Data and Systems. Moreover, possible actions to deal with these issues are discussed. This paper discusses the detail of these studies. [ABSTRACT FROM PUBLISHER]

The first possible step to achieving an understanding the design and management of complex systems is to understand what is meant by ‘complexity engineering’. Multitude of concepts in complexity engineering has been contextually developed in a wide range of disciplines by from scientists who are interested in bio-inspired methods and working in computer science or mobile robots, or they come from the area of systems engineering. A very fundamental need in complexity engineering is a general and well-developed methodology, set of design rules, and patterns for engineering ‘manageable’ and ‘value robust’ system architectures. The engineering of the Systemic Financial Risk Infrastructure Systems (SRITS) has notable resisted the application of the traditional system engineering approaches. SRITS is a complex adaptive system in the manner described by complexity science. The paper briefly presented a conceptual framework called CXLUD capable of dealing with the challenges posed by complex adaptive system, i.e. understanding, visualizing, designing, describing, managing and designing the future. The framework provides a means for system designers and managers to organize systems information in ways that allow for better collection, understanding and analysis of system information during early-phase conceptual design of complex systems. The paper summarizes the results from a series of design procedure case studies at one of the largest financial institutions in UK working on developing a complex systemic risk infrastructure projects to which the introduced decision making or way of thinking framework were applied.
