Social values and social conflict in creative problem solving and categorization.

Participants were led to expect either cooperation or conflict, and then performed K. Duncker's (1945) functional-fixedness task (Experiment 1) or E. Rosch's (1975) categorization task (Experiment 2). Those who expected cooperation, compared with those who expected conflict, were more likely to solve Duncker's task and used categories more inclusively, that is, rated low-prototypic exemplars of a category as better members of the category. In Experiment 3, the direct experience of cooperation and conflict had the same effect on categorization. In Experiment 4, participants were classified as having cooperative, competitive, or individualistic social values, and were led to expect either cooperation, conflict, or neither in a control. In the control, cooperators used categories more inclusively than competitors or individualists. Competitors used categories least inclusively in the conflict condition; in the cooperation condition, they used categories most inclusively. These results are interpreted in terms of the possible mediating role of cognitive organization in individual and intergroup conflict resolution.

A survey on bug prioritization

Daily large number of bug reports are received in large open and close source bug tracking systems. Dealing with these reports manually utilizes time and resources which leads to delaying the resolution of important bugs. As an important process in software maintenance, bug triaging process carefully analyze these bug reports to determine, for example, whether the bugs are duplicate or unique, important or unimportant, and who will resolve them. Assigning bug reports based on their priority or importance may play an important role in enhancing the bug triaging process. The accurate and timely prioritization and hence resolution of these bug reports not only improves the quality of software maintenance task but also provides the basis to keep particular software alive. In the past decade, various studies have been conducted to prioritize bug reports using data mining techniques like classification, information retrieval and clustering that can overcome incorrect prioritization. Due to their popularity and importance, we survey the automated bug prioritization processes in a systematic way. In particular, this paper gives a small theoretical study for bug reports to motivate the necessity for work on bug prioritization. The existing work on bug prioritization and some possible problems in working with bug prioritization are summarized.     

Effects of red rice flour addition on the rheological,textural, sensory and bioactive properties of wheat flour-based pan breads

Red rice, rich in fibre and phenolic contents, is one of the underutilised grains. Therefore, the present study developed the wheat/red rice flour (RRF) composites followed by its utilisation in pan breads. It led to an increase in ash and fibre contents of resultant flour combinations, but gluten network became weaker. The values for water absorption were unaffected with RRF replacements ≤15% of wheat flour. Moreover, the proximate estimates of RRF added breads demonstrated increased moisture and fibre contents. Substituted bread combinations were harder with increased gumminess and springiness values; however, cohesion decreased. The per cent change in cohesion and hardness of individual breads upon storage was lesser in composites compared to control suggesting decline in staling phenomenon. Nutritional assessment of both RRF containing flour and breads showed higher total phenolic content and DPPH radical scavenging activity compared to their respective controls. Composite breads also demonstrated reduced glycaemic index suggesting its importance for diabetic patients.
