Abstract : Education gamification has been spreading in various disciplines such as languages, computer programming, medicine, natural languages, engineering, etc. Software Engineering is our interest in this work as we saw an opportunity of contribution to enrich literature and empirical studies in this area. Traditional methods of teaching Software Engineering could significantly benefit from gamification as a complementary component in student learning outcomes. We believe we can provide our students with more effective learning environment in number of aspects including: providing enjoyable practice, immediate feedback, enhancing the sense of responsibility, enhanced engagement and performance real time tracking. In this paper, we will present our case study in adopting a computer game in software engineering course. Further, we will present the results of a course exist survey that shows the responses of 114 participating students. The analysis of the survey showed significant positive impact on number of aspects including: student engagement, learning concepts and critical thinking. The overall mean of positiveresponses was 81.2%. Keywords: Software Engineering Education, Enhancing Learning Environment, Utilizing Games in Learning.

Full textAbstract:
Differences in sets of criteria for evaluating microcomputer software are discussed. They are set against the results of three studies in which UK teachers evaluated five programs which were used in reading or English lessons. A comparison of the checklist criteria with the case study data was made using Stake's matrix of evaluation concerns [1]. This suggested a heavy emphasis on antecedents in the checklists and on transactions in the case studies. In general, neither checklists nor case studies devoted great attention to empirically measured outcomes. A possible interpretation of the results is that while the checklists focused on intrinsic evaluation, the case studies themselves focused on practical classroom issues, notably attention and motivation.

Embedded software development involves many knowledge acquisition (KA) tasks that collectively account for a significant proportion of development costs. This paper presents a pilot study that used case studies to investigate the extent to which knowledge acquired in learning tasks was used in developing a final product. Data obtained from the case studies were used to construct event chains, which trace the amount of time spent on KA tasks and the types of knowledge acquired in individual learning tasks. Knowledge acquired was separated into three categories: knowledge of data, knowledge of process, and knowledge of innovation. Each top-level category was further partitioned into productive and nonproductive knowledge depending on whether the knowledge was, or was not used, in the construction of the final product. The event chains were processed to visualize the chronological progression of how knowledge acquired in the separate categories moved between subcategories of productive and nonproductive knowledge as development progressed. Results of this analysis show trends in KA for the case studies investigated, which we plan to use in the design of future work on this topic.

: Intellectual Property Rights (IPR) are intellectual privileges that allow authors and inventors to defend their original inventions from misuse or theft. With the assistance of algorithms, clinical science has taken on a different level in recent years. Various advanced tools can be used to investigate pharmacokinetics profiling, in silico experiments, receptor simulations, drug synergistic effects, and so on. Computational scientists are making continuous efforts to figure out how to connect business models in pharmacology. However, software theft and security rights remain major concerns for all. In order to avoid such violations, IPR compliance for R&D as well as promoting machine applications is critical. This compilation will illustrate diverse software concepts, the latest patent data structures, copyright management laws for software, trade secrets, compliance rights, software patenting and contracts, artificial technology priorities and problems, licenses, and case studies relating to IPR violations in pharmaceutical and other fields.

Full textAbstract:
Aim/Purpose: This work aims to introduce and evaluate an instructional strategy that aids end-users with developing their software products during intensive project-based events. Background: End-users produce software in the labor market, and one of the challenges for End-User Software Engineering (EUSE) is the need to create functional software products without a formal education in software development. Methodology: In this work, we present an instructional strategy to expose end-users to Agile-based Software Engineering (SE) practices and enhance their ability to developing high-quality software. Moreover, we introduce a SE approach for the collection of metrics to assess the effectiveness of the instructional strategy. We conducted two case studies to validate the effectiveness of our strategy; the comprehensive analysis of the outcome products evaluates the strategy and demonstrates how to interpret the collected metrics. Contribution: This work contributes to the research and practitioner body of knowledge by leveraging SE centric concepts to design an instructional strategy to lay the foundations of SE competencies in inexperienced developers. This work presents an instructional strategy to develop SE competencies through an intensive and time-bound structure that may be replicated. Moreover, the present work introduces a framework to evaluate these competencies from a product-centric approach, specialized for non-professional individuals. Finally, the framework contributes to understanding how to assess software quality when the software product is written in non-conventional, introductory programming languages. Findings: The results show the effectiveness of our instructional strategy: teams were successful in constructing a working software product. However, participants did not display a good command of source code order and structure. Recommendations for Practitioners: Our instructional strategy provides practitioners with a framework to lay foundations in SE competencies during intensive project-based events. Based on the results of our case studies, we provide a set of recommendations for educational practice. Recommendation for Researchers: We propose an assessment framework to analyze the effectiveness of the instructional strategy from a SE perspective. This analysis provides an overall picture of the participants’ performance; other researchers could use our framework to evaluate the effectiveness of their activities, which would contribute to increasing the possibility of comparing the effectiveness of different instructional strategies. Impact on Society: Given the number of end-user developers who create software products without a formal SE training, several professional and educational contexts can benefit from our proposed instructional strategy and assessment framework. Future Research: Further research can focus on improving the assessment framework by including both process and product metrics to shed light on the effectiveness of the instructional strategies.

Although the literature studying software development methodologies (SDMs) lists several significant positive effects of the deployment of SDMs, investments into SDMs by the enterprises remain relatively limited. Strategic investments decisions, such as SDMs investments, are mostly taken with the goal of improving enterprise performance. In this paper a model for evaluation of the adoption of SDMs that focuses on the abovementioned SDMs impact on enterprise performance is proposed. The model was empirically tested in four case studies in software development small and medium enterprises (SMEs) in Slovenia. The case studies confirmed that the use of the proposed model enabled SMEs to improve SDMs related investment and adoption decisions and enabled SMEs to invest their limited resources in the most productive and competitive way. The case study experience with the proposed model suggests that its use would also bring similar benefits to larger software development enterprises.

Full textAbstract:
The process of selecting requirements for a release of a software product is challenging as the decision-making is based on uncertain predictions of customer value and development cost. This paper presents a method aimed at supporting software product development organisations in the identification of process improvement proposals to increase requirements selection quality. The method is based on an in-depth analysis of requirements selection decision outcomes after the release has been launched to the users. The method is validated in two separate case studies involving real requirements and industrial requirements engineering experts. The conclusions from the two case studies are that the method seems valuable in situations with complex release planning decisions, such as in market-driven projects. It also appears essential that participants with different viewpoints attend the root cause discussion. Requirements interdependencies seem to play a big role in release planning decision-making. In addition, successful projects can also be a source of learning.

Full textAbstract:
Aspect-oriented software development claims to improve several software engineering principles, such as modularization, abstraction and composition. The Aspect for the Space Domain project (ASSD) developed a metadata-driven approach for aspect-oriented requirements analysis. The main objectives of the ASSD project, funded by the European Space Agency , were to study the applicability and usefulness of aspect-orientation for the space domain (ground segment software projects in particular), focusing on the early stages of the software development life cycle. Therefore, this paper describes a rigorous representation for requirements analysis concepts, refines an approach for handling early aspects, and proposes a client/server architecture based on a metadata repository. The ASSD approach has been validated with two space domain case studies.

Software testing is a continuous process during the software development stages to ensure quality software products. Researchers, experts and software engineers keep going on studying new techniques, methods and approaches of testing to accommodate changes in software development because of the flexible requirement along with the changing of technology. So, developers and testers need to have effective methods, tools and approaches to create a high-quality product at an efficient cost. This paper provides an effective approach for context-driven testing (CDT) in an agile software development process. CDT is a testing approach that supports the tester to choose their testing techniques and test objectives based on specific contexts. The aim of this paper is to propose an effective approach for implementing the CDT in practice, called CDTiP. Through an analysis of two case studies using an agile development process with different contexts, we validate the effectiveness of the approach in terms of test coverage, detect errors, test effort. The empirical results show that CDTiP is suitable for the agile development process that can help the tester to detect defects faster at minimum cost. The results of this method have been applied at Enclave, an ODC Software Engineering company, on real projects.

The aim of this article is to examine the role of copresent interaction and the extent to which this can be supplanted by information and communication technology-based interaction for managing knowledge transferin distributed settings. This study draws on two case studies of small UK firms sourcing software development from India and Bangladesh. Using Nonaka and Konno’s knowledge creation theory, the role of copresent and ICT-based interactions in managing knowledge transfer is explained. The article contributes an extension of the concepts of knowledge creation theory by providing evidence of the role of copresent and ICT-based interaction for knowledge transfer in the context of offshore software development.

Collaborative product development (CPD) has become an imperative for companies to strengthen their niche values and remain competitive in the global market. However, most scholars may lack knowledge of deploying CPD in current industrial settings, and their research efforts may thus fail to fulfill practical needs. This paper presents a series of empirical case studies on distributed product development in Asia-Pacific Region. Engineering collaborations among brand-owner, manufacturer, and supplier in six product design chains (desktop PC, IC substrate, LCD monitor, bicycle, mold design, and CPU cooler) are under investigation. A systematic approach is developed that categorizes CPD into three modes based on the number of engineering BOM items and the difficulty of modularization in product design. It provides a preliminary but structured template for CPD deployment by characterizing the implications and software features of each mode. The cases also reveal values which CPD creates for the downstream supplier of a global value chain and new IT technologies enabling the collaboration process. This work is one of the early studies that analyze collaborative product development from the perspective of a manufacturer. The findings complement and corroborate theoretical studies in related research.

In this paper we present SyBeL (System Behaviour modelling Language), an XML based formalism for software system modelling. In particular, SyBeL focuses on the description of the system behaviour in order to capture its functional requirements and has been designed to fulfill some of the most trendy software engineering issues. The use of the underlying XML language makes the artifacts generated by SyBeL immediately available to further automatic manipulation (e. g., to automatically generate test cases) without the need of intermediate models, as usually done in semi-formal approaches. Moreover, we are experimenting SyBeL on a variety of practical case studies.

Teaching Scrum in Cooperation with a Software Development CompanyThe increasing use of agile methods for software development creates the need for these methods to become part of the education of future computer and information science engineers. On the other hand, teaching these methods gives us an opportunity to verify individual agile concepts and their effectiveness. For that reason, project work is an appropriate and frequently used form of teaching that enables students to get acquainted with agile methods and, at the same time, provides case studies for evaluating individual agile concepts. We describe our approach to teaching the Scrum agile method, within the software technology course, in cooperation with a software development company. Students were taught through work on a real project for which a list of requirements was submitted by the company. A co-worker of this company participated throughout the teaching period playing the role of customer's representative. During their work, students consistently used the Scrum method and at the end of each iteration they evaluated their experience by means of a questionnaire. In the article, the Scrum method is presented first, then a description of work on the project is given and finally the results of the survey are described.

Model-Based/Driven Development (MDD) constitutes an approach to software design and development that potentially contributes to: concepts closer to domain and reduction of semantic gaps, automation and less sensitivity to technological changes, and the capture of expert knowledge and reuse. The widespread adoption of pervasive technologies as basis for new systems and applications lead to the need of effectively design pervasive information systems that properly fulfil the goals they were designed for. This paper presents a profiling and framing structure approach for the development of Pervasive Information Systems (PIS). This profiling and framing structure allows the organization of the functionality that can be assigned to computational devices in a system and of the corresponding development structures and models, being. The proposed approach enables a structural approach to PIS development. The paper also presents two case studies that allowed demonstrating the applicability of the approach.

Full textAbstract:
Non-functional requirements determine the acceptance of the software application amongst its stakeholders apart from the desired functionality yet they are mostly neglected by the software development organizations. Efforts are made to enhance the success rate of the mobile app product; however, there is a lack of empirical studies available for analyzing the contribution of nonfunctional requirements towards the product success. In order to suggest mechanisms for improving product success rates, it is important to undertake the empirical study through surveys and case studies in industrial settings to analyze the software development practices focused on non-functional requirements. The analysis of data collected through empirical methods suggests that non-functional requirements are handled in the rough adhoc fashion and the number of implemented non-functional requirements is less with respect to number of implemented functional requirements. The contribution of non-functional requirements to overall development cost and time is lesser due to lesser number of requirements that undergo implementation but will grow to higher extend as their number will increase. The impact of non-functional requirements on product success rates, failure rates, overall cost and development time varies with type of development, size of organization and complexity of the undertaken mobile app projects.

In this paper we present SMDP (Scenario Model Development Process), an XML-based methodology for the description and manipulation of scenarios that are used to formalize and reuse software requirements. SMDP is an iterative and incremental process that supports scenario evolution during the requirements engineering process. The formalization of scenarios through the underlying XML-based language of SMDP makes them immediately available to further automatic manipulation (e.g., to automatically generate test cases) without the need for intermediate models, as it is usually done in semi-formal approaches. Thanks to the implementation of a software assistant environment for SMDP, the methodology is currently being experimented on a variety of case studies, in particular web applications.

Purpose – This paper aims to solve the stated limitations through (i) exploring usages of scenarios and (ii) proposing a lightweight iterative requirement exploration process that utilizes scenarios to transform the vague ideas of the developers into concrete application’s vision. The explosive growth in pervasiveness, programmability and computational capability of smartphones and tablets unlocks the possibility for many uses of technology, including end-user development (EUD) where end-users create applications as pragmatic tools for their work and hobbies. An extensive amount of research effort has been done to solve EUD challenges; however, the focus of such research lies mainly on designing and implementing software applications. Design/methodology/approach – Based on review on existing application of usage scenario in software application development, we proposed SRE – a scenario-based requirement exploration method and MobiPSE – a lightweight software process that applies SRE. Two EUD projects performed by undergraduate students were used as case studies to test and fine-tune methods. Findings – This paper proposes MobiPSE – a lightweight iterative software process that resolves around our proposed SRE method. Through case studies on MobiPSE, we confirmed that MobiPSE works in real-life scenarios and emphasized two points: ad hoc training has limited effect and lack of technical expertise can still leave a negative impact on requirement exploration process. Research limitations/implications – Because of the limited number of case studies performed for testing and tuning purpose, the proposed methods may not be able to satisfy all cases of EUD. MobiPSE can be fine-tuned further with additional case studies of different scale and team structure. Originality/value – This paper fulfils the need for a lightweight method for exploring requirements and ideas in a EUD project based on creating and analyzing possible usage scenarios.

A primary objective of this research is to enhance our understanding of the dynamic and complex patterns of suburban growth and to explore the spatial characteristics of land-use distribution during the last few decades of metropolitan expansion. Traditionally, studies of distribution of activities within metropolitan regions have been carried out on vastly aggregated spatial units of analysis based on census geography. Recent innovations in computer technology and software developoment in the field of geographic information systems have allowed much more comprehensive, high-level resolution studies to be undertaken. The study, presented in this paper, is an attempt to develop a fine-grained inspection of the evolution of suburban growth patterns through a detailed documentation of land-use-cover changes in the suburban periphery of Seattle.

This article describes a software implementation dealing with the ancient Basque musical tradition of the txalaparta. The research is different from earlier studies of the txalaparta in that, by digitizing the instrument and its performance rules, we have had to formalize and make explicit conventions that hitherto have been tacit knowledge of improvisational practice. Analysis through software development is an unusual case of musicological analysis as it demands clarity and precision, and often requires multidisciplinary approaches to understand the studied subject. We have developed software in order to analyze and understand a practice that has received little musicological analysis. By expounding musical patterns and performers' behaviors that have hitherto been difficult to analyze, we reveal the social and cultural aspects of performance practice. The txalaparta is a two-performer instrument and the software produces txalaparta rhythms and plays along with a human player, while learning and adapting to the player's style. The system helps novices to explore the rules of the txalaparta and more-experienced performers to approach the instrument from a new perspective. In this research we have applied a user-centered approach, where feedback from players using the digital txalaparta was collected. This feedback allowed us to approach the reflective vision of txalaparta players and their thoughts on the results of our research.

Data-driven storytelling helps to communicate facts, easing comprehension and decision making, particularly in crisis settings such as the current COVID-19 pandemic. Several studies have reported on general practices and guidelines to follow in order to create effective narrative visualizations. However, research regarding the benefits of implementing those practices and guidelines in software development is limited. In this article, we present a case study that explores the benefits of including data visualization best practices in the development of a software system for the current health crisis. We performed a quantitative and qualitative analysis of sixteen graphs required by the system to monitor patients' isolation and circulation permits in quarantine due to the COVID-19 pandemic. The results showed that the use of storytelling techniques in data visualization contributed to an improved decision-making process in terms of increasing information comprehension and memorability by the system stakeholders.

Software testing is undertaken to ensure that the software meets the expected requirements. The intention is to find bugs, errors, or defects in the developed software so that they can be fixed before deployment. Testing of the software is needed even after it is deployed. Regression testing is an inevitable part of software development, and must be accomplished in the maintenance phase of software development to ensure software reliability. The existing literature presents a large amount of relevant knowledge about the types of techniques and approaches used in regression test case selection and prioritization (TCS&P), comparisons of techniques used in TCS&P, and the data used. Numerous secondary studies (surveys or reviews) have been conducted in the area of TCS&P. This study aimed to provide a comprehensive examination of the analysis of the enhancements in TCS&P using a thorough systematic literature review (SLR) of the existing secondary studies. This SLR provides: (1) a collection of all the valuable secondary studies (and their qualitative analysis); (2) a thorough analysis of the publications and the trends of the secondary studies; (3) a classification of the various approaches used in the secondary studies; (4) insight into the specializations and range of years covered in the secondary texts; (5) a comprehensive list of statistical tests and tools used in the area; (6) insight into the quality of the secondary studies based on the seven selected Research Paper Quality parameters; (7) the common problems and challenges encountered by researchers; (8) common gaps and limitations of the studies; and (9) the probable prospects for research in the field of TCS&P.

A strong need for new approaches and new curricula in different disciplines in European education area still exists. It is especially the case in the field of software engineering which has traditionally been underdeveloped in some areas. The curriculum presented in this paper is oriented towards undergraduate students of informatics and engineering. The proposed approach takes into account integration trends in European educational area and requirements of the labour market. The aim of this paper is to discuss the body of knowledge that should be provided by a modern curriculum in software engineering at a master level. Also the techniques used in development and implementation of such curriculum at different universities will be described. The presented ideas are based on the experience gained in the 3 year TEMPUS1 project 'Joint MSc Curriculum in Software Engineering', which established joint master studies in software engineering. Over a three-year interval, the project managed to define a new and joint curriculum, create teaching materials and deliver the curriculum in two institutions.

Full textAbstract:
The paper is inspired by the computer based solutions developed over a period of almost 30 years. Thus, the original computer based solutions were developed for a wide range of problems: computer aided geometry for domain definition, data generators for finite element applications, output data file processors with visualization facilities, matrices defined as random access files with a wide range of subsequent applications in several disciplines and domains of science, FDM and FEM applications, customized solutions for heat transfer problems, computational fluid dynamics, experimental data reduction software applications, virtual reality facilities, semi-numeric modeling, computer based decisions. Dedicated solutions were developed for applied elasticity problems related to marine engineering problems as we as naval architecture problems: ship strength computing based on the method of initial parameters, geometrical characteristics of the cross sections, automatic calculus of the stresses of a general-shaped section and others. Most of these applications present the output data in a graphical way, in order to be more relevant for a structural analyst. Another objective was to offer not only values of different parameters, but laws of variation which may be used in other subsequent analytic studies. According to the complexity of the problem to be solved, these applications are in a range which starts at the data-crunching level up to complex and intelligent solutions, some of them being implemented in programs of tens of thousands of computer code lines. The paper presents the main features of each computer based solution, the connectivity with other solutions, the possibility to extend or adapt a given solution for a particular case study. Last but not least, there must be noticed that computer based solutions may be used in several directions of development: research, design and education..

Purpose – For decades multiple management philosophies directed toward lean production and mass were assumed as to respond to process inefficiencies and rampant consumerism, optimizing operation costs. However, new customization and flexible productions philosophies have been gaining ground in some industries, such as the agile manufacturing. From a literature review that addresses the history of this philosophy, it is clear that agile manufacturing is not fully comprehended, with very scarce information about practical cases. The paper aims to discuss these issues. Design/methodology/approach – In this paper the authors describe an exploratory methodology approach, with three semi-structured case study interviews. The goal is to study which of agile manufacturing practices are being applied in the studied companies and what is the perceived effect that these have on operational performance. Since most of these companies develop highly customized products, the role of agility on new product development can have a huge impact on their operational performance. Findings – Agile manufacturing is not yet a widespread philosophy of managing for the companies studied, being virtually unknown as a global concept. However, it was found that many of the practices of agile manufacturing are already implemented in these companies without association with this philosophy. It was also concluded, by the finding through respondents opinions, that agile practices contribute positively to the studied companies operating performance. Originality/value – The novelty of this research derives from observation of agile manufacturing practices in SMEs. This research is useful to SMEs implementing agile manufacturing principles.

This paper reports the preliminary stages of an action research project for the design, development and assessment of a computer-based game for student learning about project risk management. A computer game was created through the use of systems dynamic software (Simsoft) incorporating a land development project. The game was played by final year undergraduate construction management students who had to make decisions in identifying, assessing and managing project risks. A survey of their experience found: that most students had not experienced this form of online educational game previously in their studies despite the ubiquity of information technology for learning purposes in the university sector; there was no strong support for the idea that the acquisition of knowledge was better compared to conventional learning through lectures and books; the computer-based experience was enjoyable thus indicating it drew them into the learning environment; and student testing found they had gained understanding of the project risk management process.

Today, there is no company that does not attempt to control or assure software quality in a greater or lesser extent. Software quality has been mainly studied from the perspectives of the software product and the software process. However, there is no thorough research about how code quality is affected by the software development projects’ contexts. This study analyses how the evolution of the development effort (i.e., the number of developers and their contributions) influences the code quality (i.e., the number of bugs, code smells, cloning, etc). This paper presents a multiple case study that analyses 13 open-source projects from GitHub and SonarCloud, and retrieves more than 95,000 commits and more than 25,000 quality measures. The insights are that more developers or higher number of commits does not necessary influence worse quality levels. After applying a clustering algorithm, it is detected an inverse correlation in some cases where specific efforts were made to improve code quality. The size of commits and the relative weight of developers in their teams might also affect measures like complexity or cloning. Project managers can therefore understand the mentioned relationships and consequently make better decisions based on the information retrieved from code repositories.

Abstract Digital technologies have opened a large set of opportunities for new electronic services (e-commerce, e-health, e-studies etc.). There are many considerations that need to be made when programmers are building new application software or system software. The software needs to be attractive enough that people want to look at it. It also needs to contain all necessary information that developers want to share with their readers (customers, users) in order to help them achieve the objective for which they came to their website, use their software, or interact with their teaching packages. The oversupply of e-services products has created a need for usability research and development. “Usability means making products and systems easier to use, and matching them more closely to user needs and requirements”. Usability is a key concept of the human-computer interface and is concerned with making computer systems easy to learn and easy to use through a user-centered design process. The in-depth understanding of usability concepts and processes are critical for large-scale acceptance of new e-services and knowledge productivity. Poorly designed software can be extremely annoying to users. Smith and Mayes state that „usability is now recognised as a vital determining factor in the success of any new computer system or computer-based service”. Studies have shown that the main health problems of computer users are repetitive strain injuries, visual discomfort and stress-related disorders. Beside other risk factors, such as poor workstation design, uncomfortable work postures, long hours of computer use every day, stress, etc., also poor design and usability of the computer systems, as well as computer technical problems, add to the pressure felt by the user, which may in turn cause stress-related disorders.

AbstractScientific software is a fundamental player in modern science, participating in all stages of scientific knowledge production. Software occasionally supports the development of trivial tasks, while at other instances it determines procedures, methods, protocols, results, or conclusions related with the scientific work. The growing relevance of scientific software as a research product with value of its own has triggered the development of quantitative science studies of scientific software. The main objective of this study is to illustrate a link-based webometric approach to characterize the online mentions to scientific software across different analytical frameworks. To do this, the bibliometric software VOSviewer is used as a case study. Considering VOSviewer’s official website as a baseline, online mentions to this website were counted in three different analytical frameworks: academic literature via Google Scholar (988 mentioning publications), webpages via Majestic (1,330 mentioning websites), and tweets via Twitter (267 mentioning tweets). Google scholar mentions shows how VOSviewer is used as a research resource, whilst mentions in webpages and tweets show the interest on VOSviewer’s website from an informational and a conversational point of view. Results evidence that URL mentions can be used to gather all sorts of online impacts related to non-traditional research objects, like software, thus expanding the analytical scientometric toolset by incorporating a novel digital dimension.

A multimethod investigation of the integration of CAI into the curriculum for mildly handicapped high school students is being conducted. The research incorporates both qualitative and quantitative methods. The research design is based on an understanding that decisions, actions, and resources at different organizational levels within the school district affect the ways computers are used in resource rooms, regular classes, and computer labs. A theory-driven, structural model is being evaluated through case studies and formal observations of CAI implementation. Findings are being used formatively during Phase I of the investigation to support development of a model of effective practices that will be replicated and refined during Phase II. Preliminary findings from initial case studies in two school districts support efforts to identify, model, and refine practices in four areas: needs assessment procedures, software selection, inservice training and technical assistance, and school communications mechanisms. A special feature of the on-going study is the nature and extent of collaboration between the researchers and local school staff.

The subject of research. There has been studying a new universal method of information protection in optical text recognition systems when transmitting confidential data over open communication channels. This work develops the concept of creating a modern, simple and reliable method for protecting information during its transmission over communication channels, to determine the objective criteria for the quality of its work, to create a set of algorithms for implementing the proposed method and software for conducting experimental studies. The current work puts on the concept of creation of a simple and reliable current method for protecting information when passing it through communication channels, also to define the objective criteria for assessing the tool operation quality and to exercise the dedicated programs, which implement the proposed methods and developed algorithms. Based on the results of these studies, it must evaluate the practice effectiveness of the proposed method in terms of both the transmitted data coding/decoding reliability and the secrecy of the fact of special information transmission. Results. It is described the universal concept of producing and use of the contemporary methods of information protection in optical text recognition systems in a confidential data transmission over open communication channels. The main criteria for these systems performance quality are determined. A new combined method for encrypting transmitted messages using QR-codes with subsequent masking of the fact of data transmission by various methods of LSB-steganography is proposed. To conduct experimental studies, a text recognition program based on Tesseract OCR software version 4.0 was developed. The program in Python uses the recent resources of the OpenCV library. The dedicated software technique contributed to assessing the efficiency of the algorithms, which realized the transmitted data encryption and therefore communication links privacy. There are examples of the system operation and results of the software testing in modes of messages encoding for subsequent hidden transmission. Conclusion. The case studies acknowledge the high efficiency of the proposed method of confidential data protection when transmitting them via open networks. The technique can be taken as a basis for developing software aimed at protecting information in OCR systems offered by various manufacturers.

Purpose In the present-day context of a sharp decrease in economic and ecological resources, planned conservation and community empowerment are key strategies for sustainable heritage management, because of their cost effectiveness, increased preservation of authenticity and socially development. However, there are still very few practical implementations, so the purpose of this paper is to present applied research to real case studies, as well as to demonstrate that preventive-planned conservation is increasingly successful when linked with the empowerment of local communities and users. Design/methodology/approach This paper proposes a methodology that focuses on two complementary aspects: planned conservation (material component) – undertaken directly on buildings, through inspection, monitoring, maintenance and repair activities; community empowerment (intangible component) – afforded indirectly to users, through participatory strategies and training in prevention, maintenance and use. Findings Based on an estimation of costs, this paper suggests that preventive-planned conservation strategies (pre-damage) can be one-third cheaper than the reactive and interventionist approach (post-damage). Moreover, this study also develops innovative ICT tools for the planned conservation of the built heritage, namely a specifically designed computer software/App (“MPlan”) that can be used to compile maintenance plans. Originality/value The case studies are among the first applications of preventive-planned conservation strategies to the built heritage in Portugal. Different types of case studies are provided to better illustrate the methodological approach adopted and the results obtained. Special attention is given to the Romanesque Route, a cultural itinerary with 58 monuments (monasteries, churches, bridges, towers and a castle). illustrated manuals contribute to the empowerment of local communities and users.

A highly important part of software engineering education is requirements collection and analysis, one of the initial stages of the Software Development Lifecycle. No other conceptual work is as difficult to rectify at a later stage or as damaging to the overall system if performed incorrectly. As software engineering is a field with a reputation for producing graduate engineers who are ill-prepared for real-life software engineering contexts, this paper suggests that traditional educational techniques (e.g. role-play, live-through case studies and paper-based case studies) are insufficient in themselves. In an attempt to address this problem we have developed a games-based learning application to teach requirements collection and analysis at the tertiary education level. One of the main problems with games-based learning is that there is a distinct lack of empirical evidence supporting the approach. This paper will describe the evaluation of the requirements collection and analysis process using a newly developed framework for the evaluation of games-based learning and will focus on evaluation from a pedagogical perspective.

Industrial cyber-physical system products interleave hardware, software, and communication components. System complexity is increasing simultaneously with increased demands on quality and shortened time-to-market. To effectively support the development of such systems, we present languages and tools for comprehensive integrated model-based development that cover major phases such as requirement analysis, design, implementation, and maintenance. The model-based approach raises the level of abstraction and allows to perform virtual prototyping by simulating and optimizing system models before building physical products. Moreover, open standards and open source implementations enable model portability, tool reuse and a broader deployment. In this paper we present a general overview of the available solutions with focus on Modelica/OpenModelica, Bloqqi, and Acumen. The paper presents contributions to these languages and environments, including symbolic-numeric modeling, requirement verification, code generation, model debugging, design optimization, graphical modeling, and variant handling with traceability, as well a general discussion and conclusions.

Although Domain Analysis (DA) is important for Model Driven Development (MDD), traditional DA methods are demanding and not practical in many situations. When computer games are developed, game design (problem domain) is usually decided in a gradual way within iterations where software prototypes are constructed and playtest are performed. In such a case, it is not practical to fit a heavyweight DA in the highly iterative process. Researchers indicated that vocabularies were expected to automate game design. Such vocabularies can be reused in another form in DA tasks. In this research, the authors developed an ontology and a DA procedure based on it. To evaluate them, theoretical analysis, case studies, and a user acceptance survey were used. The results indicated that the ontology met the general requirement as a domain vocabulary, and it enhanced the DA process in an expected way. Most of external potential users (46 in total) considered the ontology useful and easy to use.

Late product delivery is a common problem in software projects. Late delivery can be attributed to software change especially in the development and maintenance phases, leading to more work than originally planned, thus increasing project completion time. One approach for managing software change is Software Configuration Management (SCM). SCM was first introduced in the 1970s to ensure the timely delivery of software products. To date, SCM implementation is supported by recognized standards, best practice, and countless commercial and proprietary tools. However, after more than 50 years, the issue of late software product delivery still prevails, questioning the practice of SCM in software organizations. One aspect of SCM that has received little focus in mainstream research is the human aspects. This study aims to identify how the competency of SCM practitioners can be assessed through the identification of SCM competency criteria and the development of a competency assessment framework. The framework was validated through expert reviews and case studies involving practitioners from the public sector, industry, institutes of higher learning and international organizations. Results confirmed the reliability of the SCM competency criteria and the plausibility of the competency assessment framework.

Full textAbstract:
Abstract The integration of user-centered design (UCD) activities into agile information systems development has become more popular recently. Despite the fact that there are many ways the merging of UCD activities into agile development can be carried out, it has been widely recognized that coordinating design activities with development activities is one of the most common problems, especially in distributed environments where designers, developers and users are spread over several sites. The main approach to coordinate UCD activities with distributed agile development is the use of informal methods (e.g. communication through using video conference tools). In addition to the temporal, geographical and socio-cultural barriers associated with this type of methods, a major limitation is a lack of awareness of how UCD activities and development activities affect each other. Furthermore, some agile project management tools are integrated with design platforms but fail to provide the necessary coordination that helps team members understand how the design and development activities affect their daily work. This research aims to support the effective management of integrating UCD activities into distributed agile development by (i) identifying the key activity dependencies between UX design teams and development teams during distributed UCD/agile development and (ii) designing a computer-based system to provide coordination support through managing these activity dependencies. In order to achieve these objectives, two case studies are carried out. Our findings revealed 10 main dependencies between UCD design teams and development teams as shown by six types of activity. In addition, the participatory design approach shows that developing a computer-based system to manage seven of these selected dependencies is achievable.

Purpose Changing customer demands, needs and desires; emerging technologies; and increasing competition among firms force software development teams to develop and then implement new software projects to satisfy their customers and become more competitive in their marketplace. In this respect, knowledge sharing is critical for project success. However, although knowledge sharing among team members has been investigated by many researchers, knowledge sharing barriers among people have rarely been addressed in project teams in general and software development teams in particular. Thus, the purpose of this study is to investigate knowledge sharing barriers in the software development team context and develop solutions that can overcome these barriers. Design/methodology/approach An exploratory multiple case design was used to explore why software team members in Turkey may be reluctant to share knowledge. In this study, the authors conducted 18 in-depth and on-site semi-structured interviews and then employed content analysis, which uses a set of procedures to make valid inferences from text, to discover knowledge sharing barriers. Findings By interviewing 18 Turkish project team managers, the authors identified knowledge-, individual- and organization-related knowledge sharing barriers among team members. They also demonstrated solutions for the knowledge sharing hesitation among team members based on the experiences of project team managers. Research limitations/implications Some methodological limitations exist in this study. Specifically, the generalizability of the sampling limits the study, which was conducted in a specific national context, Turkish firms in general and the Istanbul district in particular. It is important to note that readers should be cautious when generalizing the results to different cultural contexts. In this regard, a Turkish sample involving the Istanbul district, like that of any culturally bound research, imposes some constraints on the interpretation and application of the results. The study was conducted with in-depth interviews of only 18 managers working in seven companies. Also, this study was performed on system development teams. The results should be confirmed with more samples and different project sets. Practical implications In this study, the authors discover the reasons for knowledge sharing reluctance among team members and some solutions that will eliminate knowledge sharing problems by using case studies. The results show that the reluctance of team members arises from obstacles, which are knowledge-, individual- and organization-related. Also, the conclusions demonstrate that knowledge sharing barriers can be resolved by establishing project leadership, creating a knowledge sharing culture and considering team members’ emotions. Originality/value The present study investigated whether reluctance to share knowledge derives not only from individual barriers but also from organization- and knowledge-related barriers in a project team context. The authors discovered that knowledge sharing barriers can be resolved by establishing project leadership, creating a knowledge sharing culture and considering team members’ emotions.

Software maintenance is the task of modifying a running product previously delivered to the client, in order to correct defects, improve performance or adapt it to the environment. This task is a crucial activity for enterprises. Without it, existing systems would become rapidly out-of-date and inefficient. The purpose of this paper is to present a software maintenance approach used in small and medium-sized business (SMB) organizations in Brazil. Currently, these organizations represent 95.5% of the software companies in the country. The approach presented here indicates how SMB IT companies have improved their software maintenance processes. Multiple case studies were performed to validate this approach. The outcomes showed that strategies associated with managing users’ knowledge and development/maintenance teams are relevant to increase the maintenance process effectiveness. This approach involves three aspects: users’ knowledge management, maintenance team knowledge and the management and maintenance process. This improvement includes reducing time and also minimizing the number of tickets. The response time for tickets resolution to the end user has been reduced. In addition, IT organizations have minimized the effects associated with both staff and client turnovers.

The network of fact-checking organizations has expanded widely, and these organizations are seen as one of the important elements in the efforts to tackle the spread of disinformation, misinformation, or hoax in the society. Although the number of fact-checking organizations in all parts of the world continue to increase, scholarly studies which tries to capture the presence of fact-checking practices in Global South Countries, including Indonesia are still limited. This study uses a multi-case study method to analyze the development of fact-checking practices carried out by six organizations in Indonesia which already certified by the International Fact-Checking Network (IFCN) namely: Liputan6, Suara.com, Tirto.id, Kompas.com, Tempo.co, and MAFINDO. Since fact-checking initiatives became popular about six years ago in Indonesia, we discovered that Indonesian fact-checking organizations have grown and strengthened their presence nationally, as well as engaged with various networks of global organizations that leading the ongoing fight against hoax. However, Indonesian fact-checking organizations are still facing several challenges in the context of standardizing fact-checking methodologies, measuring and evaluating the “impact” of their fact-checking activities and related to the management of fact-checking resources. While this study attempts to contribute an overview of Indonesian fact-checking organizations, further studies on fact-checking initiatives with various methodological approaches are still needed to comprehensively look at the role of fact-checking organizations in Indonesia.

Time and resource constraints should be taken into account in software testing activities, and thus optimizing the test suite is fundamental in the development process. In this context, the test case selection aims to eliminate redundant or unnecessary test data, which is crucial for the definition of test strategies. This paper presents a systematic review on the test case selection conducted through a selection of 449 articles published in leading journals and conferences in Computer Science. We addressed the state-of-art by collecting and comparing existing evidence on the methods used in the different software domains and the methods used to evaluate the test case selection. Our study identified 32 papers that met the research objectives, which featured 18 different selection methods and were evaluated through 71 case studies. The most commonly reported methods are adaptive random testing, genetic algorithms and greedy algorithm. Most approaches rely on heuristics, such as diversity of test cases and code or model coverage. This paper also discusses the key concepts and approaches, areas of application and evaluation metrics inherent to the methods of test case selection available in the literature.

The rapid development of computer software and network technologies has facilitated the intensive application of specialized statistical software not only in the traditional information technology spheres (i.e., statistics, engineering, artificial intelligence) but also in linguistics. The statistical software R is one of the most popular analytical tools for statistical processing a huge array of digitalized language data, especially in quantitative corpus linguistic studies of Western Europe and North America. This article discusses the functionality of the software package R, focusing on its advantages in performing complex statistical analyses of linguistic data in corpus-driven studies and creating linguistic classifiers in machine learning. With this in mind, a three-stage strategy of computer-statistical analysis of linguistic corpus data is elaborated: 1) data processing and preparing to be subjected to a statistical procedure, 2) utilizing statistical hypothesis testing methods (MANOVA, ANOVA) and the Tukey post-hoc test, and 3) developing a model of a linguistic classifier and analyzing its effectiveness. The strategy is implemented on 11 000 tokens of English detached nonfinite constructions with an explicit subject extracted from the BNC-BYU corpus. The statistical analysis indicates significant differences in the realization of the factors of the parameter “Part of speech of the subject”. The analyzed linguistic data are employed to build a machine model for the classification of the given constructions. Particular attention is devoted to the methodological perspectives of interdisciplinary research in the fields of linguistics and computer studies. The potential application of the elaborated case study in training undergraduate, master, and postgraduate students of Applied Linguistics is indicated. The article provides all the statistical data and codes written in the R script with comprehensive descriptions and explanations. The concluding part of the article summarizes the obtained results and highlights the issues for further research connected with the popularization of the statistical software complex R and raising the awareness of specialists in this statistical analysis system.

Sustainable development, as a new idea of development, has become a source of worldwide concern. Many elements, such as society, economics, resources, and the environment, have a role in the long-term evolution of the ecological environment. It is an intricate mechanism. Based on previous research, this study investigates the relationship between environmental design and the long-term evolution of the ecological environment in the new age. The following are the specifics. First, the conceptual model of ecological sustainable development is constructed, and the “low-carbon idea” environmental design approach is addressed. Then, using Tianjin as an example, an assessment method for environmental sustainable development in environmental design is constructed based on summarizing past studies. The ecological features are included in the DPSIR model, and the “low-carbon concept” environmental design method is used in Tianjin Binhai New Area. The findings show that, with the continued development of Binhai New Area, the adjustment of industrial structure, and the gradual improvement of people’s awareness of urban sustainable development, the ecological environment’s sustainability index will improve, with per capita ecological carrying capacity rising from 2019 and the per capita ecological carrying capacity of agricultural and livestock products, which are 0.09 hm2 and 0.09 hm2, respectively, rising significantly. Since 2019, the per capita ecological footprint has also declined.

Cloud computing is a supercomputing that integrates large-scale and scalable computing, storage, data, applications, and other distributed computing resources for collaborative work in the form of virtualization technology as the basis and the network as the carrier to provide infrastructure, platform, software, and other service’s model. Green GDP (GGDP) is an assessment indicator for regional sustainable development. Hence, the evaluation index on GGDP and greening of the national economic accounting system (SNA) are the hotspots of current ecological and economic studies. In the recent years, Zhejiang’s economy has achieved rapid development, and there are also problems of high input and high consumption of natural resources, thereby restricting its sustainable development. Based on the statistical data of Zhejiang Province during 2000–2017, the GGDP within the sustainable development context is calculated using the system of integrated environmental and economic accounting (SEEA). The results indicated the following: (1) The GGDP accounted for 79.29%–96.78% of Zhejiang's GDP during the study period, which showed volatility upward trend, resulting from the significant environmental protection and conservation of natural resources in the study area. But economic development was heavily dependent on resources, and the local government still strengthened the work of improving resources and environment. (2) The proportion of secondary industry in Zhejiang Province fluctuated downwards during the period of 2000–2017, and the tertiary industry showed a volatility upward trend, which exceeded the proportion of the secondary industry, indicating that Zhejiang Province is from an industry-led economy to a service-oriented economy change.

Full textAbstract:
The article discusses methods for developing a user interface in web applications. The interface plays a vital role in software. From a visual point of view, its design and accuracy are of paramount importance to display the exact amount of information for the intended user. Every minor decision you make when designing a user interface can have a positive or negative impact on your software. Thus, the purpose of this study was to compare user interface design methods and propose appropriate options for choosing design approaches based on case studies and research results. The study examines various design methods - user-centered design, activity-centered design, data-driven design. To better understand the similarities and differences between these three methods in a business environment, this document discusses each method in terms of its foundations, processes, and results. Based on the above description of the main characteristics of design approaches, they are presented more systematically. Taking into account the main characteristics of design approaches and what really determines them, 10 different criteria for assessing the quality of design were identified, which are important distinguishing features. A framework is provided for evaluating and comparing them to help the reader evaluate which one best suits a particular context. The structure of the processes of their application in the development of a new software product or service is presented. In practice, this analysis can be used: - as a reference list of application options for design approaches and methods, in particular for the development of software products and services. - To decide which approach and design method will be most effective in a particular context - provide links for further analysis of related aspects - human-computer interaction, user interaction, software development life cycle, software development teams design.

Background The research marketplace has seen a flood of open-source or commercial mobile health (mHealth) platforms that can collect and use user data in real time. However, there is a lack of practical literature on how these platforms are developed, integrated into study designs, and adopted, including important information around cost and effort considerations. Objective We intend to build critical literacy in the clinician-researcher readership into the cost, effort, and processes involved in developing and operationalizing an mHealth platform, focusing on Intui, an mHealth platform that we developed. Methods We describe the development of the Intui mHealth platform and general principles of its operationalization across sites. Results We provide a worked example in the form of a case study. Intui was operationalized in the design of a behavioral activation intervention in collaboration with a mental health service provider. We describe the design specifications of the study site, the developed software, and the cost and effort required to build the final product. Conclusions Study designs, researcher needs, and technical considerations can impact effort and costs associated with the use of mHealth platforms. Greater transparency from platform developers about the impact of these factors on practical considerations relevant to end users such as clinician-researchers is crucial to increasing critical literacy around mHealth, thereby aiding in the widespread use of these potentially beneficial technologies and building clinician confidence in these tools.

Abstract:There is a need for consensus on the quantity of data that must be available in a computer-based information system of a health care organization. In this paper we take up the issue of defining the data content of an information system and introduce the concept of Essential Data Sets with an explicit methodology which was applied to define a data set for the Maternal Health Services program. A key step in the method was a recognized technique used in systems development process called data modelling, in this case infological modelling, by an interdisciplinary group. A preliminary set of 86 data elements was identified and it provided the foundation for development of an application software for discussion and a real-world testing framework. The acceptability of the data set was tested in a laboratory perspective by retrospective data entry from records of 94 pregnant women registered at a maternal health care center in Sweden. Data from a total of 1,318 prenatal visits, an outcome visit, and a postnatal visit for each woman was entered into a computer using the software, with no loss of information. Thus, in a short-term perspective the acceptability of the data set was demonstrated. The software has since been implemented for pilot prospective studies at sites in India and Sweden. The use of a common data protocol is an essential foundation for patient outcome research, especially as the trend of health care management has changed from a “process of care” orientation to an “outcome of care” orientation.

The commercial success of cellular phone systems during the late 1980s and early 1990 years heralded the wireless revolution that became apparent at the turn of the 21st century and has led the modern society to a highly interconnected world where ubiquitous connectivity and mobility are enabled by powerful wireless terminals. Software defined radio (SDR) technology has played a major role in accelerating the pace at which wireless capabilities have advanced, in particular over the past 15 years, and SDRs are now at the core of modern wireless communication systems. In this paper we give an overview of SDRs that includes a discussion of drivers and technologies that have contributed to their continuous advancement, and presents the theory needed to understand the architecture and operation of current SDRs. We also review the choices for SDR platforms and the programming options that are currently available for SDR research, development, and teaching, and present case studies illustrating SDR use. Our hope is that the paper will be useful as a reference to wireless researchers and developers working in the industry or in academic settings on further advancing and refining the capabilities of wireless systems.
