The relationship among software design quality, development effort, and governance practices is a traditional research problem. However, the extent to which consolidated results on this remain valid for open source (OS) projects an An emerging body of literature contrasts view as alternative proprietary explains that there exists continuum between closed projects. This paper hypothesizes approach OS end continuum, becomes less formal. In turn formal hypothesized require higher-quality code...
Direct, solid-state X-ray detectors based on organic single crystals are shown to operate at room temperature, in air, and voltages as low a few volts, delivering stable reproducible linear response increasing dose rates, with notable radiation hardness resistance aging. All-organic optically transparent devices reported.
Background: The risk of chronic diseases increases markedly with age and after menopause. An increase in bodily iron following menopause could contribute to this phenomenon increased diseases. We aimed investigate how various biomarkers change advancing age, according sex menopausal status. Methods: enrolled community-dwelling individuals available information on ferritin, transferrin, iron, hepcidin, soluble transferrin receptor levels from the Prevention Renal Vascular Endstage Disease...
A quality degradation effect of proprietary code has been observed as a consequence maintenance. This effect, called entropy, is cause for higher maintenance costs. In the Open Source context, fundamental tenet open software developers. As consequence, principle measured by entropy cannot be assumed to valid. The goal paper analyze applications measuring evolution costs over time. Analyses are based on cost data collected from sample 1251 application versions, compared with estimated...
Researches on green data centers have defined guidelines and end-to-end methodologies to increase energy efficiency. Most of these approaches require a disrupting reengineering the infrastructure significant upfront investments. Smaller need reach objectives with more incremental approach. The EnergIT project proposes methodology related tools that support redesign toward greater efficiency based three main levers: 1) physical repositioning servers optimize air flow circulation cooling,...
Previous contributions in the empirical software engineering literature have consistently observed a quality degradation effect of proprietary code as consequence maintenance. This effect, referred to entropy has been recognized be responsible for significant increases maintenance effort. In Open Source context, is fundamental design principle. As consequence, effort applications may not show similar increasing trend over time. The goal this paper empirically verify sample 4,289 community...
This paper focuses on semantic networks that represent the user opinions expressed by social media users a given set of topics. These are found to follow power-law degree distribution nodes, with few hub nodes and long tail peripheral nodes. While there exist consolidated approaches supporting identification characterization hu b research analysis multi-layered periph eral is limited. In media, influencers. However, literature provides evidence structure influence networks, emphasizing disti...
We have designed a new semantic network for the English language annotated with two types of domain knowledge: 1) general knowledge, represented as sentiment polarity attached to relationships between words and 2) contextual such domain-specific proper names. In context social networks, Twitter, evolution maintenance are particularly critical tasks analysts not incur in quick obsolescence. show how set semi-automated methodologies applied our promising results on preliminary tests run using...
This study draws from the product development literature to hypothesize symmetry between social networks and design structures in software projects. Findings support this hypothesis but also reveal significant differences Open Source Closed In Source, structure reflects organizational of its team whereas impacts network. Further, drives productivity projects while Intriguingly, over time network begins resemble that Source.
