Sign Error

The article discusses correcting of typos due to erroneous use of the so-called soft sign in Skolt Sami, one of the most common orthographic symbols, and the most common source of typographic errors. The discussion is based upon the suggestion mechanism of an existing open source Skolt Sami speller. The discussion shows that with an improved suggestion mechanism, the speller is able to restore a single soft sign error in over 97 % of the cases, and remove a hypercorrect soft sign as first correction in 90 % of the cases. Allowing the target form to be within top-5, the correction performance is well above 99 %. Improving the suggestion mechanism also had a positive impact of its overall performance, rising the percentage of target forms within top-5 from 74.1 % to 84.7 %.

This paper describes the design and evaluation of an ERP system design course, which utilizes experiential learning theory along with open ERP sys-tem to provide the students with a holistic and cost-free learning environ-ment. The objective of the course is to familiarize students with the ERP se-lection and implementation life-cycle. When designing the pedagogical framework, the goal was to help students, especially those with little to no working experience to acquire the necessary knowledge, and develop the practical technical experience. Additionally, it was necessary to help students appreciate the depth and issues involved in the ERP system selection and implementation life-cycle. Lectures, case discussions, system demos with interactive labs, and group projects were used all together to enable in depth learning of the proposed topics. We focus on open source ERP system to provide the students with the required hands-on experience, and also to demonstrate that such approach can be utilized even by low resource universities. This paper includes details of the proposed framework. The proposed framework was taught and evaluated in a 1-semester graduate level course at the university of Jeddah, in Jeddah, Saudi Arabia. The course design was in-directly assessed using a survey, and the results revealed the positive impact that the proposed framework had on students’ learning outcomes. The results of the assessment support that experiential based learning using open source ERP systems can lead to improved learning outcome.

Run Time

Uninitialized variables have been a source of errors since the beginning of software engineering. Some programming languages (e.g. Java and Python) will automatically zero-initialize such variables, but others, like C and C++, leave their state undefined. While laying aside initialization in C and C++ might be a performance advantage if an initial value can't be supplied, working with such variables is an undefined behavior, and is a common source of instabilities and crashes. To avoid such errors, whenever meaningful initialization is possible, it should be used. Tools for detecting these errors run time have existed for decades, but those require the problematic code to be executed. Since in many cases the number of possible execution paths are combinatoric, static analysis techniques emerged as an alternative. In this paper, we overview the technique for detecting uninitialized C++ variables using the Clang Static Analyzer, and describe various heuristics to guess whether a specific variable was left in an undefined state intentionally. We implemented a prototype tool based on our idea and successfully tested it on large open source projects.

The debate over green ICT has been triggered by media during the climate change summit in Kyoto in 2007. This was when the industry tried to build up a clean and non-polluting image. While the Copenhagen summit on the environment failed to produce a conclusive decision, it is now clear that its carbon footprint is a remarkable factor in all business decision making. Governments around the world have set up defined programs and targets that companies have to reach. ICT is aimed at achieving reduction in the 2% of CO2 emission levels. The advantage of the positive impact of Green ICT initiatives would be seen in the clear results in management‘s decision making. However, the adoption of green ICT programs gives the opportunity to fully rethink over current business process and develop new solutions. The benefit of environmental friendly companies can also affect the overall performance and deliver measurable results in terms of customer‘s preference, brand value, ROI, not to count the needed change of behaviour at individual and personal level (such as waste disposal). The chapter wants to outline those topics and properly address the issues behind what the author considers as equivalent to the next industrial revolution.

This study investigates the potentially facilitative effects of internal and external attention-drawing devices—output and visual input enhancement—on the acquisition of English relativization by adult English as a second language (ESL) learners. Specifically, the study addresses: (a) whether the act of producing output promotes noticing of formal elements in the target language (TL) input and affects subsequent learning of the form; and (b) whether such output- induced noticing and learning, if any, would be the same as that effected by visual input enhancement designed to draw learners' attention to problematic form features in the input. These questions were examined in a controlled experimental study in which the requirements of output and exposure to enhanced input were systematically varied. A computer-assisted reconstruction and reading task was used as the vehicle of presentation of the target input materials. The major findings are: (a) Those engaged in output-input activities outperformed those exposed to the same input for the sole purpose of comprehension in learning gains; (b) those who received visual input enhancement failed to show measurable gains in learning, despite the documented positive impact of enhancement on the noticing of the target form items in the input; and (c) in view of the above, no support was found for the hypothesis that the effect of input enhancement was comparable to that of output. The subsequent discussion centers on reexamining the construct of noticing and argues for the need to consider levels and types of processing in order to account for how sensory detection can lead to learning.

In a world filled with big data, mathematical models, and statistics, the development of strong quantitative skills is becoming increasingly critical for modern biologists. Teachers in this field must understand how students acquire quantitative skills and explore barriers experienced by students when developing these skills. In this study, we examine the interrelationships among gender, grit, and math confidence for student performance on a pre–post quantitative skills assessment and overall performance in an undergraduate biology course. Here, we show that females significantly underperformed relative to males on a quantitative skills assessment at the start of term. However, females showed significantly higher gains over the semester, such that the gender gap in performance was nearly eliminated by the end of the semester. Math confidence plays an important role in the performance on both the pre and post quantitative skills assessments and overall performance in the course. The effect of grit on student performance, however, is mediated by a student’s math confidence; as math confidence increases, the positive effect of grit decreases. Consequently, the positive impact of a student’s grittiness is observed most strongly for those students with low math confidence. We also found grit to be positively associated with the midterm score and the final grade in the course. Given the relationships established in this study among gender, grit, and math confidence, we provide “instructor actions” from the literature that can be applied in the classroom to promote the development of quantitative skills in light of our findings.

AbstractThe role of non-coding contributors in Open Source Software (OSS) is poorly understood. Most of current research around OSS development focuses on the coding aspects of the project (e.g., commits, pull requests or code reviews) while ignoring the potential of other types of contributions. Often, due to the assumption that these other contributions are not significant in number and that, in any case, they are handled by the same people that are also part of the “coding team”. This paper aims to investigate whether this is actually the case by analyzing the frequency and diversity of non-coding contributions in OSS development. As a sample of projects for our study we have taken the 100 most popular projects in the ecosystem of NPM, a package manager for JavaScript. Our results validate the importance of dedicated non-coding contributors in OSS and the diversity of OSS communities as, typically, a contributor specializes in a specific subset of roles. We foresee that projects adopting explicit policies to attract and onboard them could see a positive impact in their long-term sustainability providing they also put in place the right governance strategies to facilitate the migration and collaboration among the different roles. As part of this work, we also provide a replicability package to facilitate further quantitative role-based analysis by other researchers.

Abstract. Indoor mapping is an essential process in several applications such as the visualization of space and its utilization, security and resource planning, emergency planning and location-based alerts and, last but not least, indoor navigation. In this work, a completely free and open-source (FOS) approach to map indoor environments, and to navigate through them, is presented. Our tests were carried out within Sapienza University of Rome public buildings; in detail, Letters and Philosophy faculty and Engineering faculty indoor environments were mapped. To reach this goal, only open source software such as Quantum GIS (QGIS) and open-source platforms like Open Street Map (OSM) and its indoor viewer, Open Level Up (OLU) were adopted. A database of indoor environments of the two faculties, completely compatible with OLU, was created through QGIS. In this way, a public territorial information system of classrooms, offices and laboratories is accessible to everyone who can, hence, add or modify the information, following the principle of crowdsourcing and of Volunteered Geographic Information (VGI). The developed procedure is now standard and its outputs accepted by the OSM community. Hence, the long-term developments of this project are the proposal for the volunteered and cooperative indoor mapping and design of strategic buildings and infrastructures (hospitals, schools, public offices, shopping centers, stations, airports etc.), starting from the available information (indoor layouts) and knowledge acquired through experience of people who normally work inside them and/or visit them frequently. In this context it is possible to state that the development of VGI for internal maps for strategic buildings, infrastructures and denied GNSS environments, not only supports and improves internal and external navigation without interruption, but can also have a significant positive impact on security and emergency management.

The Relationship

Purpose The purpose of this paper is to empirically investigate and clarify the relationship between business process improvement and employees’ behavior. More precisely, the purpose is to test whether a business process improvement initiative has a positive impact on performance and employees’ behavior, namely, motivation, communication and knowledge sharing. Design/methodology/approach The empirical research of this paper was conducted in the year 2013 in an ICT company on 52 employees who worked in the company’s R&D Centre. Business process improvement is analyzed in the change of work method for software development. Two projects of software development were observed. The data about the projects were collected by using the company’s documentation. The data about employees’ behavior were collected by a specially designed questionnaire. Findings Business process improvement led to better results and overall performance. Furthermore, it was found that business process improvement enhanced three important elements of employees’ behavior. These are motivation, communication and knowledge sharing. Research limitations/implications The main limitations of this study are small research sample, focusing on just the way of business process improvement and on only one company. Therefore, the results cannot be generalized and considered as being generally accepted. Practical implications The findings of this study could be useful for ICT companies because it shows the benefits of the Kanban method. Originality/value The major contribution of this study is to prove the positive impact of business process improvement initiatives on overall performance and on the special elements of employees’ behavior. This cognition enhances the existing knowledge on business process improvements.

In recent decades, the fabrication of composite membranes using nanoparticles has played a vital role in membrane distillation (MD) technique. It could make available membranes with superior characteristics as excellent candidates for MD technique. The most well-known obstacles regarding the MD method are the low productivity and high cost. Thus, fabricating membranes with superior properties is a significant challenge. In the current study, a composite membrane has been fabricated using 0.25, 0.5, and 0.75 weight percent (wt.%) of graphene nanoparticles (GNPs) with polystyrene (PS) as a base polymer and characterized using SEM, FTIR, and contact angle. The characterization results prove the successful fabrication using electrospinning and the validity of the fabricated membranes to be applied to direct contact membrane distillation (DCMD). In addition, a DCMD experimental setup has been designed to examine the performance of the fabricated membranes and compare the performance of blank PS with composite PS/GNPs membranes. The results show that all fabricated membranes produced an approximately similar average flux of about 10 kg/m2 h, while the highest GNPs wt.% showed the highest salt rejection. Accordingly, this composite membrane has been examined at different operating parameters and showed stable performance. Moreover, feed temperature and the rate of flow have a positive impact on the overall performance of the DCMD.
