In this study, we explored the students' computer-supported collaborative learning behavior based on the Facebook platform. Sixty two senior college students major in Information Management took Decision Support System (DSS) class. Besides the lectures and class discussion, the students participated in the DSS Facebook for collaborative learning. We found that students' characteristics (e.g., gender and mindset of learning) are important factors to affect their Facebook usage behavior and learning performance. The students using DSS Facebook more often get better performance in their final projects, learning satisfaction and the online communication behavior survey. We also found that gender affects the usage of social networks platform. For instance, male students use social networks platform several times per week and get better performance in online communication, learning satisfaction and creativity self-efficacy.

Although a vast majority of crowd sourcing tasks are for ethical purposes, the anonymity and global reach of online labor markets also create a clearinghouse for unethical crowd sourcing tasks. Recent studies show a majority of students have engaged in academic dishonesty using the Internet, and a growing number find this behavior is acceptable. We conduct a study to see if crowd workers will provide solutions to exams and homework assignments, and knowingly permit these solutions to be used for this purpose. For those who don't agree, we examine if additional financial incentives can entice them. Our findings indicate most crowd workers are willing to permit the use of their work, however, for those that are unwilling, additional financial incentives have little effect on altering their decision.

The SOA architecture primarily based on Web services is experiencing a steady adoption, although its growth was lower than expected when it was launched, mainly because of security related concerns. Web services inherited many well-known security problems of Web applications and brought new ones. Major data breaches today are consequences of bad input validation at the application level. This paper presents a way to implement an input validation model for Web services which can be used to prevent cross-site scripting and SQL injection through the use of predefined models which specify valid inputs. The proposed WSIVM (Web Services Input Validation Model) consists of an XML schema, an XML specification, and a module for performing input validation according to the schema. A case study showing the effectiveness and performance of this mechanism is also presented.

3D cell nuclei segmentation from fluorescence microscopy images is a key application in many biological studies. We propose a new, fully automated and non parametric method that takes advantage of the resolution anisotropy in fluorescence microscopy. The cell nuclei are first detected in 2D at each image plane and then tracked over depth through a graph based decision to recover their 3D profiles. As the tracking fails to separate very close cell nuclei along depth, we also propose a corrective step based on an intensity projection criterion. Experimental results on real data demonstrate the efficacy of the proposed method.

This paper presents a new code compression method where we use different dictionaries, all of them are based in traditional Huffman algorithm. Our method reduces code size by up to 34.5% (including all extra costs) and presents an improvement of almost 7% over the traditional Huffman method. We performed simulations using Simple Scalar and analyzes using the applications from benchmark MiBench and use the embedded processor ARM.
