Focused on the welfare of the poor and disadvantaged, philanthropic organizations involved in the distribution of food, clothing and other goods rarely have adequate devices for identifying the needs that might exist and what already exists in nearby organizations. This worsens the response to the needy and the organizations that have goods to donate, which are not able to stock the goods forever. Therefore, we propose a new online collaboration platform for the exchange of goods between the various organizations in order to improve communication, foster collaboration, and fulfil the mission of each organization more efficiently and effectively, and, at the same time, increasing the involvement of the whole community.

Using principles from architecture to inform HCI design

Full text: PDFPDF

The field of Human-Computer Interaction (HCI) Design has traditionally been very inclusive, as it emerged from the confluence of seemingly disparate disciplines, such as Computer Science, Information Design and even Rhetoric. However, this interdisciplinary orientation has not translated into direct conversations with other disciplines in order to explore a variety of actionable design strategies, which can inform future systems and interactions. This position paper explores one such possible relationship, arguing that HCI can benefit by drawing from other design fields, specifically Architecture. In order to understand how architectural design can inform better information design, we compare and contrast architectural design elements and principles to information architecture design elements within websites. We then use examples of both typical and award-winning architecture to compare to common and award-winning information architecture and website design, in order to draw parallels between the principles at work. The comparison specifically explores how architects of physical spaces create a sense of place through context and transition spaces, and provide users with a thorough understanding of they space they are navigating, concluding with implications for transfer into information design.

doi>10.1145/2618168.2618172
Full text: PDFPDF

In this paper, statutory auditors’ profiles will be defined on Computer Assisted Audit Tools and Techniques’ intention to use and use concerning the influence of statutory auditors firms’ dimension (number of collaborators, number of financial auditors and number of statutory auditors), peers impact (other statutory auditors and the professional group influence on the professional context) and social influence (people and firm support). Additionally, previous research on the experience with tools and its influence on the acceptance are documented this research group, and also the professional experience (number of years of professional experience). The variety of computer assisted audit tools available in the firm and its impact on the acceptance is also addressed. In the reference group, was possible to conclude that firm dimension, peers and social influence and experience have a positive impact on Computer Assisted Audit Tools and Techniques’ acceptance. However, the number of available tools has a negative impact on intention to use confirming that is not relevant to have several tools but to be expert in one or two tools.

The development of the new software game gave emphasis and importance to the role played by the user discussion group during the development phase; they were sometimes called upon to participate in testing and they contributed to changes that improved the overall software’s. Some more concrete methods include discussion groups to stimulate the emergence of new ideas and evaluate the gamification concepts. According to this approach, the web designers of two gamification software projects in e-banking using Mutual Funds and Warrants were encouraged to build the first playable version of the gamified business software. After a live introduction to a group of users, it was requested their opinion in an open questionnaire with six questions, permitting them to identify without restrictions the needs, modifications and opinions. The method has identified a wide range of games characteristics and web design changes, as was expected by both business and customers. In conclusion, the use of the discussion group and open questionnaires were effective methods for the project team, to check preview the perceptions and customer acceptance in adopting the software gamified. In this study, we identified the users’ perceptions, resumed in a diagram “the most relevant factors in an e-business game”. Our practical contribution is for the web designers and project managers who with this methodology, may check if their software will have good adoption.

The gamification is growing in e-business and the banks are looking for new ways to get more customers on their websites. Therefore, it is important to study what are the most appreciated features of the website that could influence the behaviour of the customer to use an electronic banking system with game features. The gamified e-banking suggests that rich elements/features associated with the games could influence other variables and therefore increasing the client loyalty, to spend more time and increasing the transactions on the website. The aim of this study is to look into the influence of gamification in the e-banking system. Based on the research of 180 publications and 210 variables that could influence the intention to use a certain technology this study develops a theoretical model representing the gamification influence on ease of use, information, web pages characteristics, web design and on the intention to use an e-banking with game features. The results from an online survey of 219 e-banking customers show that the gamification had a positive impact on all variables; special has a medium positive influence in web design and information and a large positive influence on customer intentions to use. Further analysis shows that the website ease of use plays has also a medium positive influence on the intention to use an e-banking gamified. Our findings also show that the clients give more importance to an attractive graphical and architecture website design, and less to web pages with so much information or having pleasure in using an e-banking system.

Massive open online courses (MOOCs) are black swans. A black swan is an unexpected event that emerges from reality and alters the reality itself. MOOCs have affected supply and demand in higher education. MOOCs distribute knowledge, classes on many areas of expertise for free. Millions of users, from all over the world are enrolling MOOCs courses. Universities are sharing resources and knowledge in the Internet no matter who or why. This paradigm shift has an impact on people’s life. So, how can universities survive if they are giving knowledge for free? This paper presents a literature review on MOOCs. We also modulate this reality to minimize the jeopardy and maximize the good opportunities that MOOCs bring.

Full text: PDFPDF

Training and user documentation aim at people being able to use IT when returning from training. Such transfer is in general difficult to achieve. Based on a model of IT use learning, two types of diagrams in documentation were compared in a field study; instructions showing the sequence of how to carry out an operation by means of screen shots and structural models showing data structures without user interface elements. Instructions were in general favoured. Even if the instructions only to a small extent were presented with projector during training, the trainees stated that they learnt a lot from these presentations. The learning outcome might have been the existence of an operation and where in the software to locate it. While primarily intended as help for understanding data structures, the trainees also used structural models as guides for carrying out operations. Instructions in particular, but also structural models were utilised by the trainees after the training sessions, hence helping transfer. Trainers should include both types of models in courses.

Geocasting in vehicular adhoc networks using particle swarm optimization

Full text: PDFPDF

Recently, geocast routing has been intensively investigated for reliable and efficient dissemination of information. This can be attributed to the fact that in Vehicular Adhoc Networks (VANETs), group of vehicles moving on road always shares geographical region and most of the Intelligent Transport Systems (ITS) applications require sending information to all vehicles belonging to a given geographical region. Various techniques have been used for geocasting such as peripheral node based Next Hop Vehicle (NHV) selection, voronoi diagram based NHV selection, cache agent based NHV selection etc. These techniques have shown limited performance due dynamic characteristics of VANETs. In this paper, we have proposed Geocasting through Particle Swarm Optimization (GeoPSO) protocol. GeoPSO selects NHV by using Particle Swarm Optimization (PSO) technique. The empirical results show that GeoPSO outperforms tradition techniques in terms of packet deliver and network load.

Full text: PDFPDF

Adapting technological environments to users is a concern since Mark Weiser launched the concept of ubiquitous computing and, in order to do that, is necessary to understand users’ characteristics. In this context, the purpose of this paper is to present a study about students’ mobility habits within a university campus, having the intention of getting insights towards the best place to set an interactive public display and of predicting the main characteristics of the audience that will be present on that spot in forthcoming periods. Thus, the envisioned results of this work will allow the adaptation of the contents exhibited on the device to the audience. To perform the study, a set of logs of accesses to the university’s Wi-Fi was used, data mining techniques were implemented and forecasting models were built, using the line of work suggested by the CRISP-DM methodology. As result, students profile were built based on past wireless accesses and on their scholar schedules, and three time series models were used (Holt-Winters, Seasonal Naive and Simple Exponential Smoothing) to predict the presence of students on the envisioned spot in future periods.

doi>10.1145/2618168.2618180
Full text: PDFPDF

This research proposes an evaluation model to measure a computer programming learning system success, for helping students to overcome learning difficulties. Teachers use programming learning environments, as computer-assisted instruction systems. The proposed model is supported in a the theory of information systems success evaluation, and in the characteristics of a virtual programming learning tool. The used tool was a web-based virtual robot learning system. Results presented here suggest the main features that this type of solution should include.

The development of applications and solutions to support collaborative environments targeted to real businesses means that often there is a choice to be performed: Either the business is forced to comply with the specifications and technologies defined in the collaborative environment or otherwise it is the development of solutions that must be specific and hardcoded for the specificities of each business. Whereas the first approach has the advantage of allowing future improvements centrally, as well as promoting enterprises to follow best-practices, has as major drawback the need forthese enterprises to change, which is not admissible. On the other hand, specific and dedicated development is much more focused and targeted to the enterprises’ real needs; however, this approach not only is much more expensive to the enterprise itself, but it also creates a dependency towards the software developer, and makes the system less prone to evolution and best-practice following. This paper presents a third approach to the development of this type of solutions, which consists of a static, evolvable architecture and processes, complemented by a suite of specific modules that are meant to tailor the application to the needs of the business, proposed in the form of contributions to the system. This approach is then exemplified in the scope of a realuse-case, as it is being implemented and validated in the context of the FP7 TIMBUS project.

Full text: PDFPDF

Business Intelligence (BI) platforms are applications to analyze critical business data so as to gain new insights about business and markets. The new insights can be used for improving products and services, achieving better operational efficiency, improve competitiveness, and fostering customer relationships. However, we notice that BI is not yet a reality in Small and Medium Enterprises (SMEs) and it’s even unknown in many of these organizations. The implementation of BI in organizations depends on their specificities. It is essential that the information available on platforms and their functionality comes clearly to organizations. Only a correct choice, in response to business needs, will allow powerful data that results in gains and business success. For this purpose, we have developed a comparative analysis of the existing capabilities in the various BI tools, which is intended to assist the selection of the BI platform best suited to each organization and/or business area. In this paper, we study and compare seven of the most used open source BI platforms: Actuate, JasperSoft, OpenI, Palo, Pentaho, SpagoBI and Vanilla.

Web-based communities and internal social networks have become common part of the work environment in many organizations. These Enterprise Social Networks (ESN) link employees, capture organizational knowledge and support collaboration in virtual teams. Even though ESN intend to break up knowledge silos, improve communication and foster knowledge sharing, their limited ability to cover corporate workows hinders them from realizing their full potential. Information is often scattered either across several systems outside of ESN software or distinct groups and conversations within ESN due to the lack of support of cross-team communication patterns required in complex business processes. To discover gaps we use a real-world example and analyze a critical sales process. Thereafter, extensions to existing software are proposed with the goal to better cover the end-to-end collaboration in virtual teams. We discovered limitations in the group concepts and the mechanisms of sharing content between groups in ESN and conducted a first evaluation of our enhanced concepts with process experts.

An accountable set of dynamic changes are happening on day to day basis in the software industry. So the change is the inevitable and heart of the software industry. Although many software processes and models, tools, standards exist and practices are set, still the industry is facing huge challenge in the design, build and reuse of software components, thereby facing an issue in delivering an effective software product of high quality within a short time meeting customer expectations. Eventually, there is a critical need to throw a light in the direction of understanding related software components and methods to identify similar components so that the components of similar nature may be clustered as a single group. In this paper we propose a novel similarity measure by modifying the Gaussian function. The similarity measure designed is used to cluster the text documents and may be extended to cluster software components and program codes. The similarity measure is efficient as it covers the two sides of the term-axes.

Based on the previous and ongoing work of the development of GSG, an extensible expert system shell tool to support creative work involving shape computing with Shape Grammars, this paper shows an evolution and refinement of the system. A refined class structure and the line intersections types appropriate for matching shapes in the process of shape grammar rule application are presented. Operations for the algebras of shapes (which are essential in the mechanics of the application of rules in shape computing) are discussed, for both maximal and non maximal shapes. In particular, details and tests of the implementation of these operations for the maximal case are also shown.

This paper presents an examination and performance analysis of Redundant Array of Inexpensive Disks ver. 5 (RAID-5) and its comparison to the single disk drive performances. The focus is on the influence of the number of disks in RAID-5 to the globally achieved disk performances. Initially, we have applied the M/G/1 queue for the needs of analytically modeling a single disk performances. Then, we have set up an adequate analytical model for underlying file system. Finally, the proper workload analytical model has been defined and applied for four different RAID performance cases. Additionally, to provide a more comprehensive analysis, we have defined three types of workloads. The obtained test results have shown that there is a solid slowing in the RAID-5 performance, specifically for the workloads which are dominated by small updates. Increasing the number of disks has a different impact on the performances and depends on the workload. All benchmark results are interpreted based on a mathematical model of workload, file system access times and single disk access times.

Computer Assisted Audit Tools and Techniques, CAATTs, represent nowadays a regular presence on Chartered Accountants’, CAs, daily tasks: several previous researches state that Generalized Audit Software is present in CAs’ routines and some specific tools are conquering their space among these professionals’ preferences. Present research reveals that “Data Extraction and Analytics” and “Sampling” tools are the most common Information Technologies on Auditing work. Computer Assisted Techniques related to data mining are still not expressive in this reference group or are only utilized by a small group of experts, mainly at big companies. New trends on CAATTs are rising mainly as a consequence of changes in business and technology. This paper intends to draw the big picture on that topic and anticipate new trends on the area: Big Data, Cloud Auditing, Emerging Technologies will be presented. This paper discusses also how can auditors be prepared to the new trends and proposes a new classification for Computer Assisted Audit Tools and Techniques.

An information system for investment advisory process

doi>10.1145/2618168.2618191
Full text: PDFPDF

Information systems in the form of Decision Support Systems (DSS) and Expert Systems (ES) have been used for considerable years in finance, marketing, portfolio management and other fields. Most of these systems use artificial intelligence techniques. Systems have been designed to address the problem of allocating the wealth of an individual across various assets in order to maximize return subject to a certain risk. This problem is known as the investment portfolio management problem. This problem can be comprised of the investment advisory problem and the portfolio allocation problem. This paper proposes an information system for the investment advisory problem to aid the wealth managers in providing regulatory compliant investment advice. The system considers the behavioral traits of the customer and calculates his risk appetite. It then does a risk scoring and allocates the wealth of the customer proportionately in different investment asset classes. It then checks the suitability of the advisory note prepared by the wealth manager subject to a set of inbuilt rules.

Full text: PDFPDF

This paper describes a desk study in which a user manual dating from 1925, describing how to operate a table loom, was verified for conformance to an ISO standard that lists requirements for software user documentation and was last revised in 2008. A remarkably high degree of conformance was established. It is discussed whether this is coincidental, or more fundamentally related to the way in which the documentation of software tools is regarded as quantitatively rather than qualitatively different from the documentation of physical tools. The paper concludes by making a case for academic research resulting in guidelines for software documentation that take into account the specific nature of software, and the specific problems that users encounter when working with software.

The decision on the pair degree/institution, upon application to higher education will be the most important in the life of a young person. Despite recent developments, applicants to higher education still don’t know many of the available indicators that could influence their decision. In this paper we propose a portal with a simple design which presents all the available and relevant indicators. It offers also necessary resources and options thus is the candidate and not the state or any other entity, to prioritize their priorities. The portal will allow each candidate to query data, by degree and institution, and make individual simulations, giving weights to more relevant criteria, in order to find a hierarchy of degrees/institutions which most closely match to his goals, thus creating a personal ranking.

Understanding the states of learners at a lecture is expected to be useful for improving the quality of the lecture. This paper investigates the possibility of use of a simple electroencephalograph MindTune for activity recognition of a learner. The authors considered three kinds of activities for detecting states of a learner, and collected electroencephalography data with the activities by MindTune. Then, they applied K-nearest neighbor algorithm to the collected data, and the accuracy of the activity recognition was 58.2%. The result indicates a possibility of using MindTune for the activity recognition of learners.

Data visuals are everywhere, from the most trite like bar charts to the most complex like network graphs, and computer animations and simulations. While the diversity and abundance of data visuals is clearly a result of our technological revolution, data visuals are, above all, the products of people working for other people. This is nowhere more evident than in science and technology, where the safety and well-being of entire populations is at stake. However, once we shift our focus from data visuals to the human element, human and cultural factors take precedence over the visuals and even the science and engineering that warrant the visuals. What factors are those? How do they affect the conceptualization, production, and communication of data visuals? What does this mean for those involved in the practice, research, teaching and learning of science and technology? To answer these questions, I will report on the results of a pilot study the Visualizing STEM Research Synergy Cluster at NMT did with science and technology students. I will relate the results to research in data visualization, science and technology studies (STS), and cultural and human factors. And I will discuss implications of the pilot study for the visual communication of science and technology.

Presentations by local technical writers have shown a surprising diversity of writing and content governance scenarios on mature software companies. Mature companies have unique business problems that require unique technical and human solutions.

On Altitude Software, writers struggle to control the complexity created by the organic growth of a mature software suite. As a response, feature-based documentation was rewritten in 2003 as task-based documentation, and is being rewritten again since 2010 into custom topic patterns.

Over time, Altitude Software learned to hire and train highly technical writers. Technical writers in Altitude Software became professional learners that must learn specific writing techniques, become experts in the product, and approach the background expertise of specific user audiences.

Scalability is essential for web applications with massive numbers of users. The high growth rates observed in web based systems having hundreds of thousands of users accessing it continuously led to major response time problems for users who are trying to receive information at the same time. As more and more users access a web site, one needs to know how the performance varies. The main challenge Facebook engineer’s face, despite receiving billions of users on a daily basis, is keeping the website online and functional. The current architecture of Facebook is very large and consists of many technologies and thousands of servers. In this paper Facebook’s architecture and how it handles scalability issues is going to be described, helping to have a better understanding of how Facebook actually works.

The wide spread of new media developed new ways of communicating. When technical subjects are communicated, either in a user manual, advertisement or in science, the use of new media are becoming even more important. As a consequence, a “communication designer” need new skills. These new skills involve text construction, manipulation of images, sound, video and all the new environments (especially social networks). This is far from the traditional Graphic Designer or Technical Writer learned skills. So, the need of communicating technical issues is broad, it covers a wide range of contexts, from professional to semi-professional contexts. Design of Communication knowledge is also important to other practitioners that are not necessarily “Communication Designers”.

This paper describes an existing database of geolocated tweets that were produced in Portuguese regions. The existing database was collected during eight consecutive days and contains about 307K tweets, produced by about 11K different users. A detailed analysis on the content of the messages suggests a predominance of teenagers and young adult authors that use Twitter as a way to communicate their feelings, ideas and comments to their colleagues. An overview of the dataset suggests that tweets have a very personal content, often describing family bonds and school activities and concerns. This is a suitable source of information for a number of tasks, including sociolinguistic studies, sentiment analysis, among others.

The massive access to the Internet has changed the way we interact and relate. Social networks registered a massive adoption. Free and open source software (FOSS) eases the diffusion of social networks. Moreover, FOSS content management systems (CMS) allow the development and customization without requiring high technical knowledge. WordPress, the most used CMS, is widely used in the proliferation of social networks. This CMS disposes a social network plugin, the BuddyPress. In this paper the authors describe the architecture and functionalities of the BuddyPress. It’s also presented a SWOT analysis on BuddyPress.

Software development cost estimation using similarity difference between software attributes
Divya Kashyap, A. K. Misra
Pages: 1-6
doi>10.1145/2503859.2503860
Full text: PDFPDF

Although software industry has seen a tremendous growth and expansion since its birth, it is continuously facing problems in its evolution. The major challenge for this industry is to produce quality software which is timely designed and build with proper cost estimates. Thus the techniques for controlling the quality and predicting cost of software are in the center of attention for many software firms. In this paper, we have tried to propose a cost estimation model based on Multiobjective Particle Swarm Optimization (MPSO) to tune the parameters of the famous COstructive COst MOdel (COCOMO). This cost estimation model is integrated with Quality Function Deployment (QFD) methodology to assist decision making in software designing and development processes for improving the quality. This unique combination will help the project managers to efficiently plan the overall software development life cycle of the software product.

Social networking websites have grown rapidly in recent years. Many people are involved in several virtual networking websites. However, many users are not aware of the potential risk that may occur as a result of improper actions when using social networking websites. Although a lot of benefits can be received by using virtual communities, privacy and security problems may occur. The aim of this paper is to enhance the protection of users’ personal and sensitive information that exist in social networking websites. In particular, this paper discusses privacy settings, security questions, and third party applications involved in using Facebook website. The results of this paper highlights the need for a regular review of privacy settings as well as a clear policy to control the interaction between users and applications.

Understanding temporal dynamics of ratings in the book recommendation scenario
Paula Cristina Vaz, Ricardo Ribeiro, David Martins de Matos
Pages: 11-15
doi>10.1145/2503859.2503862
Full text: PDFPDF

Libraries have large growing book collections. Library users have difficulty in browsing the whole collection when choosing new books to read, particularly when looking for books without a defined goal. In this case, recommendation systems come in hand and play an important role in improving library usability. Recommendations are based on ratings and the quality of recommendations depends on the quality of the ratings. In this paper, we adapted an item-based collaborative filtering algorithm by incorporating temporal information. We, then, analyze the influence of the rating age in final predictions. Our findings suggest that prediction quality improve when some conditions are met. Moreover, user tastes are more correlated with recent rated books than old ones.

ERP measure success model; a new perspective
Fernando Bento, Carlos J. Costa
Pages: 16-26
doi>10.1145/2503859.2503863
Full text: PDFPDF

This paper addresses the problem of defining and evaluating the success of ERP throughout the life cycle of the information system. In order to solve this problem, many of the theoretical and empirical contributions on the success of the information system are analysed and discussed.

This approach allows the development of a new model; especially in Delone & Mclean supported research.

This work will try to establish a different perspective on the success of the ERP and can be an encouragement to some organizations or the many researchers that will be engaging in these areas, in order to help achieve more clearly the expected performance in the acquisition phase of ERPs. Many times that performance does not always happen.

The web industry has evolved very rapidly since its beginning from read-only static content to fully interactive applications. As opposed to traditional software applications, the development of a web application is a challenging and complex task involving many phases with different type of stakeholders. In fact, the majority of web applications do get shredded away or fail to gain popularity due the simple fact that the application does not meet and achieve usability goals with the accuracy and level outlined by the experts at the early. In this research studies, we propose a communication channel to automate the process between user interface prototyping and formalized software architecture in order to bridge the gap between the different stakeholders. As user interfaces provide a rich source of user requirements, an approach is being investigated to formalize requirements analysis from user interface using a proposed Mockup-based navigational diagram that can be translated to other architectural models and therefore the possibility of automated code generation.

My favorites (bookmarks) schema: one solution to online information storage and retrieval

doi>10.1145/2503859.2503865
Full text: PDFPDF

Dealing with the overwhelming daily amount of online information is perhaps the biggest challenge faced by all computer users, whether they are novices or experienced professionals. How, where and when to store information sources, such as websites, is becoming increasingly difficult as people spend more of their life online and use the internet in all aspects of their lives. Our survey of 202 internet users found that although 85% of the participants regularly use the favorites (bookmarks) function, 73% still have trouble finding a website that they have recently visited. Whether the strategy is to bookmark in a single massive list and use the search tool, or to bookmark into folders and sub-folders several levels deep, appears to make very little difference. This research proposes a contrarian approach, giving users a highly structured favorites (bookmarks) schema using only two levels, consisting of four main headings and 12 sub-headings. An open card sorting task was used to validate the utility of such an approach. The results and their impact towards a future user-based knowledge structure are presented in this paper.

An exploratory study was conducted into the interaction with documentation displayed by users of an unknown software tool. Five adult men were observed during their work with a software simulation of a fictitious machine for the production of liquorice. Their only source of information on the machine’s functioning was its printed user manual. The log data from the observations was analyzed with a view to pinpointing interesting patterns of behaviour that deserve further, more formal, research.

Full text: PDFPDF

The development of multiple web applications with features of video games gave way to a new trend called Gamification. However, there isn’t a clear explanation that allows the connection of the elements of the game applications with non-game features, mainly in traditional highly regulated financial sector. The aim of this study is to investigate the acceptance of a business application Gamified in e-banking. Based on the Technology Acceptance Model (TAM), the results from an online survey of 183 customers show that the Gamified application had a positive impact on the acceptance of this new concept in e-banking. Our findings show that perceived ease-of-use have a strong positive influence on costumers intentions and on the perceived usefulness. Further analysis and model modification show that perceived usefulness and enjoyment have positive influence on perceived ease-of-use. The results also show that the customers have accepted and used the Gamified application to manage their investments and bought more mutual funds thus increasing the chance to win the game.

Semiotic circles: an inclusive methodology in HCI design
Andreas Karatsolis, Kenrick Fernandes
Pages: 70-74
doi>10.1145/2503859.2503870
Full text: PDFPDF

Advances in technology have penetrated all aspects of our lives. Consequently, our interactions with devices and other users become ubiquitous, demanding well thought-out design approaches. In the last few years, several methodologies for HCI design have been proposed, which attempt to capture users’ thoughts and other information from multi-layered user hierarchies [1-2]. However, these methodologies do not scale well in hierarchical situations, where participants can be of differing levels of expertise/authority. We have designed an inclusive methodology which acknowledges all participant perspectives and facilitates interaction between stakeholders. Semiotic Circles draws inspiration from well-established methodologies such as Paper Prototyping, Think-Aloud protocol and Object Labeling. This methodology combines visualization on paper with a tangible tagging system, enabling the final aggregated model to be genuinely inclusive, rather than the result of designers/researchers choices.

E-learning systems are widely used from academia to industry. The usage of e-learning systems raises new research contexts. Multiple collaborative learning systems were implemented to improve people interaction, communication, working, coordinating activities, socializing and learning. E-learning systems play an significant role in the learning activities. This paper presents a critical literature review on e-learning systems; it is composed by two main parts. The first part contains a literature review on the e-learning concept and evolution. The second part consists on the concept different perspectives overlapś according to the various e-learning dimensions.

Some prospective approaches for the shift of programming paradigms

Pages: 87-93
doi>10.1145/2503859.2503873
Full text: PDFPDF

Building information systems (IS) for the communication and distribution of information requires proper approaches. The most suitable programming approach must be applied since all phases of IS development will be affected if the wrong approach is chosen. Programming approaches are also known as programming paradigm (PP)s. The most suitable selection for these various PPs will of course rely on the programmer’s decision making and problem solving skills. However, it has been reported that programmers are trained more on the programming language’s syntax and semantics rather than the PPs itself. Since each PP is a concept of its own, it could be difficult for some programmers to transition or shift to the next sequence of PP(s). This paper explores some prospective approaches for the shift of PPs and discusses how they could help the shift to the next PPs.

An extended synthesis algorithm for relational database schema design

Full text: PDFPDF

Relational model is the most essential database model for decades and is examined in various ways. A very important concept in the relational modeling is the concept of dependencies. Particularly a set of functional dependencies and its equivalent minimal cover are discussed here for synthesizing third normal form relations. A traditional synthesis algorithm have been used to reduce the set of functional dependencies, F, into an equivalent minimal cover. This cover is then used to develop a relational schema; however, a given set of functional dependencies may have more than one minimal covers. In turn, different minimal covers may give rise to different relational schema. Database designers had already been agreed upon the use of popular inference rules of Armstrong to obtain minimal covers from the set F of functional dependencies. Despite the frequent use of the traditional synthesis algorithm, there is still a lack of formality and simplicity support in that algorithm to produce a minimum cover, especially; the step(s) of the algorithm in which the set of functional dependencies of F are used to make left-irreducible remain informal. In this paper, an extension is proposed to the synthesis algorithm that aids in to produce an optimal minimal cover more systematically from the given set of functional dependencies. The optimal minimal cover obtained by this extension would be appropriate for synthesizing third normal form relational schema from the universal relation scheme.

Full text: PDFPDF

The purpose of this research is studying the key dimensions that explain the use of social network systems. In order to achieve this purpose, it was identified a model that explains the use of social systems. The model is an extension of the Technology Acceptance Model, considering enjoyment as construct and the impact of effective use in the intention to use. It was performed an empirical research to identify that ease of use has generically a minimal impact. Results also showed that intention to use is largely influenced by perceived usefulness, and effective use is influenced mainly by enjoyment.

doi>10.1145/2503859.2503876
Full text: PDFPDF

The purpose of this paper is to present a game development approach in a context of an open source community.

The problem of community creation and management is an important issue in this context. Identifying who is involved, what are their motivations, as well as the tasks that they perform and tools used is a particularly relevant issue.

In this paper, we propose a graphical modeling approach that may be used to model open source software communities. Then, we describe the use of this approach in a case of game development.

The comprehensive performance analysis of striped disk array organizations – RAID-0

doi>10.1145/2503859.2503877
Full text: PDFPDF

Redundant Array of Inexpensive Disks version RAID-0 is a block-stripped disk array without redundancy. This paper provides results of RAID-0 performance examination when compared to a single disk drive. Particular emphasis is put on how the number of disks in the RAID 0 configuration influences the performance results. The presented analysis relies on setting up the analytical model of a single disk based on M/G/1 queue and in the same manner defining analytical model for the file system access time. Finally, we have set up an analytical model for the RAID-0 workload related to four specific types of RAID performances. We have defined three types of workloads, generally dominated by relatively small objects. Test results have shown a superior behaviour of RAID-0 when compared to a single drive and a significant performance enhancement as the number of disks increases. All benchmark results are interpreted based on a mathematical model.

Full text: PDFPDF

This paper provides a partial review of the understanding of innovation in academia and policy circles. Science and technology can be said to have surfaced around the 1950s as an industrial policy tool. Dominant views on innovation began along the lines of the “Linear model”, a perspective that has stayed influential. In the 1980s a major re-conceptualisation of the innovation process matured, this came with the introduction of the “chain-linked model”. By the 2000s new research on innovation suggested a substantial update and revision of the concept of innovation, encapsulated by the “multi-channel model”. This paper discusses these conceptual models in a sequential way, and ends providing thoughts on how they can be understood in a policy context.

Full text: PDFPDF

This paper presents an innovative platform that permits the aggregation of multiple e-mail and accounts, to make the day to day handling of e-mail messages more manageable and pleasant. The new product illustrates a launching supported by low level of investment and the search for innovation based in the finding of an unexplored need in the fast moving of the information and communication technology (ICT) global market. Low financial and human resources are the main problems of start-ups when disputing big companies. But one of the challenges of the ICT market can be an opportunity to a start-up, which is be focus on the solution instead of the technology. Just a small part of the market buys technology for technology’s sake and maybe that, in part, can explain the quite conservative behaviour inside the IT industry, as Butje explained (1). Although there is a high demand for new solutions, most of the time to help simplifying the existent offer, very few want to be the first to try it. Users of this platform will benefit from not having to enter credentials for each of their e-mail accounts. To be able to access all e-mail accounts at once, the user logs on to the platform and the (pre-configured) e-mail accounts are visible. The user shall then have the option to view all e-mail messages within the same area (the messages are highlighted with different colours (or logos) depending on which account they are destined for). Another view is to have separate areas (or tabs) for each email account. The functionality shall also be extended to instant messaging accounts.

This paper, presents a web-based service for web and mobile platform that optimizes the freight and warehouse management, as in calculating the volume for cargo and freight. Design the service concept and the marketing planning for the launch of this disruptive product for the management of the space, illustrates the creation of an entrepreneurial mindset aiming a win business in profitability as well as in sustainable growth within the complex and uncertain systems information market (1). According to Hsieh et al (2) taking profit of an opportunity is combining search and recognition of a valuable problem-solution. This new information system service, it will allow firms to reduce time and costs in the management of the store space. Through a data entered in the data base, we calculate the required load and vehicles. Thus, companies will save money. How? By making route optimizations, and improving conditioning of the loads. Save on transportation, fuel, human resources, and will have an accurate calculation of the cost for transportation in production/distribution of goods.

This paper presents the analysing of the opportunity by identifying a problem and designing a product to solve it in a win-win strategy for both customers and the entrepreneurial firm. Also it shows the marketing strategy and communication actions, in order to tangibilize the benefits of this new information system to the customer in a period of economic crisis and where the old methods of managing the cargo and freight should be abandoned.

As for Gamification, it is about business software with game characteristics, understanding the software development process will improve the practices, and will more than likely, improve the business itself (make it more efficient, effective, and less costly and mainly collect a positive influence from the customers). This study aims to develop a framework that provides the mechanisms to ensure that the software will have game characteristic and that clients will recognize it as Gamification. Our results show that the five-step framework proposal applied to the Gamification project management on this study, the Spiral development model, and the group discussion results into a positive effect on customers and e-business. The spiral development methodology used for the development of this application showed to be the appropriated for this type of project. The tests with discussion-groups proved to be a key “tool” to identify and adapt the game characteristics that has led to the improvement of customer perception of socialness, usefulness ease of use, enjoyment and ease of use that probed to have a strong positive impact on the intention to use the game.

Communication skills are essential to a successful career in computing. You may be an excellent programmer, but if you can’t explain your work to your peers then your career will quickly plateau. This means the most important language you should master during your graduate studies is not C# or Java — it’s English.

Whether it’s writing reports for class, writing conference or journal papers to summarize research results, or writing a long document such as a thesis or a dissertation, it’s all writing. Your special challenge is explaining complex concepts to your readers in a way that they can easily understand. Fortunately, this is a skill that you can learn.

Full text: PDFPDF

Nowadays the organizations need to increase the efficiency rate of the service support, responding faster occurrences (e.g. in internal support like help-desk or end user support). The use of Knowledge Management (KM) platforms is becoming a solution adopted by most organizations. However, the way how this knowledge is organized and managed together remains a problem that affects the quality of the services provided. To contribute to the solution of this problem, in this paper it is presented a Conceptual Model, in the framework of KM to a telecommunications organization or services, applying best practices as the use of Information Technology Infrastructure Library (ITIL). This framework should help answer questions regarding: How extent to which the explicit knowledge is useful for organizations? Are the employees feedback taken into consideration? It is important to understand the difference between an incident and a problem, and to what extent this distinction contributes together with knowledge management and end user support. With this approach it is intended to analyze the extent to which the information available in electronic document is useful for the organization, taking into account the ever-changing technology markets.

The ubiquitous adoption of the internet means that as long as internet connections are available, communication can take place independently of geographic locations. In this paper, we demonstrate how the same can hold true for physical exploration of a remote location: we present a mobile robot that can be controlled over the internet from within a browser. Our robot executes commands issued by a remote operator, but at the same time ensures its own safety by autonomously avoiding obstacles such as walls and stairs. The operator receives a video feed and the readings of other sensors from the robot. Our system is built entirely using open source software, and we have made available all source code for our system and the schematics for the LEGO Mindstorms NXT robot.

Massive Open Online Courses (MOOC), the most recent branch in the Open Education Resources (OER) movement, take a step forward in courses dissemination, integrating reputation and network aspects. Although MOOC’s enrollment success in delivering courses to thousands of students per course, universities face several barriers that must be overcome in order to turn MOOC’s sustainable. In this paper a literature review is presented. We propose a conceptual model of a MOOC, named Metaversia with knowledge-building based framework. The conceptual model is validated by a prototype implemented on Drupal, an open source content management system.

Full text: PDFPDF

The success of Open Source Software (OSS), along with the importance that their communities have created around their project’s and products (Ubuntu, LibreOffice, Android and CyanogenMod, etc) has recently attracted the attention of researchers and commercial companies. While the first ones are learning lessons from the success of OSS and applying some of them, the second ones are also acquiring knowledge. They are now more open minded and import the apprenticeship to develop their systems, implement it to their structure and even help to make them compatible with their products (like HTC, Motorola, Samsung and Sony Ericsson do with CyanogenMod). These OSS communities are normally called communities of practice and they are a group of people who are informally bounded by their common interest and practice in a specific domain. The LibreOffice Portuguese Community has been in great growth and trying to answer the “The Document Foundation” (TDF) requests. The “real time” translations of the package and recently the development of the IT and LibreOffice Open Manual are examples. The author feels that it is time to make a short scientific analysis, through a reading of the creative processes and production, based on international scientific developments and conclusions. The objective of this paper is to make the first step of a study of how LibreOffice is contributing to the sustainable development in Portugal.

Open Source is an increasingly interesting vehicle for dissemination of project results within the R&D and ICT FP7 communities. PROSE, an FP7 ICT project, is promoting open source adoption by creating a software forge that provides project management, source code hosting, and development support for the ICT and European open source projects. In this paper we present the key requirements for a software forge resulting from a public consultation of projects in the European space, and the corresponding instantiation of an open source software forge, publicly available at opensourceprojects.eu. We also discuss the relevance of a centralized collaboration platform for European projects, and the value presented by such an approach as opposed to current source code repositories.

Pages: 46-48
doi>10.1145/2503848.2503858
Full text: PDFPDF

The effect of a new globalised world where technologies and methodologies mature rapidly is a constant change in business paradigms and assets. Tools, technology and formats become easily deprecated and replaced by others, and legal and licensing affairs are subject to constant legislation changes. Hence, a business seeking to preserve its assets for long term becomes very prone to problems of this nature. This paper presents an approach to analyse the risks coming from various sources which may affect enterprise business continuity, discussing the problems and issues relevant to it, and proposing long-term digital preservation as a mitigation action to handle some of these determined risks, and the implementation of a framework to support these concepts, in the context of the Seventh Framework Programme (FP7) TIMBUS project.
