Open Source Software Development Process Model

The global open source movement has provided software users with more choices, lower software acquisition cost, more flexible software customization, and possibly higher quality software product. Although the development of open source software is dynamic and it encourages innovations, the process can be chaotic and involve members around the globe. An Open Source Software Development (OSSD) process model to enhance the survivability of OSSD projects is needed. This research uses the grounded theory approach to derive a Phase-Role-Skill-Responsibility (PRSR) OSSD process model. The three OSSD process phases -- Launch Stage, Before the First Release, and Between Releases -- address the characteristics of the OSSD process as well as factors that influence the OSSD process. In the PRSR model, different roles/actors are required to have different skills and responsibilities corresponding to each of the three OSSD process phases. This qualitative research contributes to the software development literature as well as open source practice

Eradication of mucoid Pseudomonas aeruginosa with fluid liposome-encapsulated tobramycin in an animal model of chronic pulmonary infection

Despite controversies associated with forms and value of antibiotic therapy for cystic \ufb01brosis patients, antibiotherapy remains a cornerstone in the management of those patients. Locally administered liposome-encapsulated antibiotics may offer advantages over free antibiotics, including sustained concentration of the antibiotic, minimal systemic absorption, reduced toxicity, and increased ef\ufb01cacy. We evaluated the ef\ufb01cacy of free and encapsulated tobramycin in \ufb02uid and rigid liposomal formulations administered to rats chronically infected with Pseudomonas aeruginosa. Chronic infection in lungs was established by intratracheal administration of 10\u2075 CFU of a mucoid variant of P. aeruginosa PA 508 prepared in agar beads. Antibiotic treatments were given intratracheally at time intervals of 16 h. After the last treatment, lung bacterial counts were determined and tobramycin levels in the lungs and kidneys were evaluated by high-performance liquid chromatographic analysis and microbiological assay. Two independent experiments showed that animals treated with encapsulated tobramycin in \ufb02uid liposomes had a number of CFU less than the minimal CFU number required to be statistically acceptable compared with 6710\u2076 CFU per pair of lungs for animals treated with encapsulated tobramycin in rigid liposomes, free antibiotic, or liposomes without tobramycin. Tobramycin measured in the lungs at 16 h after the last treatment following the administration of encapsulated antibiotic was still active, and its concentration was 6727 \u3bcg/mg of tissue. Low levels of tobramycin were detected in the kidneys (0.59 to 0.87 \u3bcg/mg of tissue) after the administration of encapsulated antibiotic, while 5.31 \u3bcg/mg of tissue was detected in the kidneys following the administration of free antibiotic. These results suggest that the local administration of \ufb02uid liposomes with encapsulated tobramycin could greatly improve the management of chronic pulmonary infection in cystic \ufb01brosis patientsNRC publication: Ye

Experience Marketing at Retail Environments

The economy in which consumers live today is considered the experience economy. One of the industries that is growing in this economy is the entertainment industry. Additionally, this industry is not only limited to conventional entertainment contexts today. For instance, many retail contexts have started to operate according to the rules of this industry. Today, the entertainment value that consumers construct within and derive from the market is highly dependent on the experiences they find in retail contexts. Entertaining experiences play the focal role in most retail contexts due to the high level of positive managerial outcomes, such as economic value. Therefore, there is a growing need to understand the phenomenon of commercial experiences that provide entertainment and their role in various retail environments in different cultures. This conceptual chapter aims to understand how successful retailers utilize experience marketing to attract more consumers. © 2014 by IGI Global. All rights reserved
