Myths and Realities about Online Forums in Open Source Software Development: An Empirical Study

The use of free and open source software (OSS) is gaining momentum due to the ever increasing availability and use of the Internet. Organizations are also now adopting open source software, despite some reservations, in particular regarding the provision and availability of support. Some of the biggest concerns about free and open source software are post release software defects and their rectification, management of dynamic requirements and support to the users. A common belief is that there is no appropriate support available for this class of software. A contradictory argument is that due to the active involvement of Internet users in online forums, there is in fact a large resource available that communicates and manages the provision of support. The research model of this empirical investigation examines the evidence available to assess whether this commonly held belief is based on facts given the current developments in OSS or simply a myth, which has developed around OSS development. We analyzed a dataset consisting of 1880 open source software projects covering a broad range of categories in this investigation. The results show that online forums play a significant role in managing software defects, implementation of new requirements and providing support to the users in open source software and have become a major source of assistance in maintenance of the open source projects

A Services Science Major in a Bachelor of Science (IT) Program: The Case of UAE University

This paper presents a proposed design for a new undergraduate major in services science within a bachelor of science in information technology program. Potential students in the major will be Emerati nationals with strong verbal skills but sometimes weak writing, math and problem solving skills. Math and problem solving skill are essential in the new services dominated environment, so it is important that these skills be developed in students if the nation is to continue to lead the region in IT service provisioning. The curriculum proposes three new courses and inclusion of four existing course from related majors

Evaluating the Demand for Soft Skills in Software Development

An analysis of 500 advertisements for IT positions focuses on the soft skills mentioned in the ads, revealing which soft skills are in high demand for software development and which ones are neglected despite their importance

Soft Skills Requirements in Software Development Jobs: A Cross-Cultural Empirical Study

Purpose: Most of the studies carried out on human factor in software development concentrate primarily on personality traits. However, soft skills which largely help in determining personality traits have been given comparatively little attention by researchers. The purpose of this paper is to find out whether employers’ soft skills requirements, as advertised in job postings, within different roles of software development, are similar across different cultures. Design/methodology/approach: The authors review the literature relating to soft skills before describing a study based on 500 job advertisements posted on well-known recruitment sites from a range of geographical locations, including North America, Europe, Asia and Australia. The study makes use of nine defined soft skills to assess the level of demand for each of these skills related to individual job roles within the software industry. Findings: It was found that in the cases of designer, programmer and tester, substantial similarity exists for the requirements of soft skills, whereas only in the case of system analyst is dissimilarity present across different cultures. It was concluded that cultural difference does not have a major impact on the choice of soft skills requirements in hiring new employee in the case of the software development profession. Originality/value: Specific studies concerning soft skills and software development have been sporadic and often incidental, which highlights the originality of this work. Moreover, no concrete work has been reported in the area of soft skills and their demand as a part of job requirement sets in diverse cultures, which increases the value of this paper

Soft Skills and Software Development: A Reflection from the Software Industry

Psychological theories assert that not everybody is fit for every task, as people have different personality traits and abilities. Often, personality traits are expressed in people’s soft skills. That is, the way people perceive, plan and execute any assigned task is influenced by their set of soft skills. Most of the studies carried out on the human factor in IS concentrate primarily on personality types. Soft skills have been given comparatively little attention by researchers. We review the literature relating to soft skills and the software engineering and information systems domain before describing a study based on 650 job advertisements posted on well-known recruitment sites from a range of geographical locations including, North America, Europe, Asia and Australia. The study makes use of nine defined soft skills to assess the level of demand for each of these skills related to individual job roles within the software industry. This work reports some of the vital statistics from industry about the requirements of soft skills in various roles of software development phases. The work also highlights the variation in the types of skills required for each of the roles. We found that currently although the software industry is paying attention to soft skills up to some extent while hiring but there is a need to further acknowledge the role of these skills in software development. The objective of this paper is to analyze the software industry’s soft skills requirements for various software development positions, such as system analyst, designer, programmer, and tester. We pose two research questions, namely, (1) What soft skills are appropriate to different software development lifecycle roles, and (2) Up to what extend does the software industry consider soft skills when hiring an employee. The study suggests that there is a further need of acknowledgment of the significance of soft skills from employers in software industry

Protein-protein interaction based on pairwise similarity

<p>Abstract</p> <p>Background</p> <p>Protein-protein interaction (PPI) is essential to most biological processes. Abnormal interactions may have implications in a number of neurological syndromes. Given that the association and dissociation of protein molecules is crucial, computational tools capable of effectively identifying PPI are desirable. In this paper, we propose a simple yet effective method to detect PPI based on pairwise similarity and using only the primary structure of the protein. The PPI based on Pairwise Similarity (PPI-PS) method consists of a representation of each protein sequence by a vector of pairwise similarities against large subsequences of amino acids created by a shifting window which passes over concatenated protein training sequences. Each coordinate of this vector is typically the E-value of the Smith-Waterman score. These vectors are then used to compute the kernel matrix which will be exploited in conjunction with support vector machines.</p> <p>Results</p> <p>To assess the ability of the proposed method to recognize the difference between "<it>interacted</it>" and "<it>non-interacted</it>" proteins pairs, we applied it on different datasets from the available yeast <it>saccharomyces cerevisiae </it>protein interaction. The proposed method achieved reasonable improvement over the existing state-of-the-art methods for PPI prediction.</p> <p>Conclusion</p> <p>Pairwise similarity score provides a relevant measure of similarity between protein sequences. This similarity incorporates biological knowledge about proteins and it is extremely powerful when combined with support vector machine to predict PPI.</p
