A comprehensive study of CMMI based framework for collaborative software maintenance

Software maintenance (SM) environment is a highly complex area, knowledge-driven and collaborative. Therefore, Capability Maturity Model Integration (CMMI) is a process improvement approach that provides organizations with the essential elements of effective processes that ultimately improve their performance. We propose a new framework of CMMI based on Multi-Agent System (MAS) to identify the process measurement of SM. The proposed MAS architecture includes three types of agents: Personal Agent (PA), Maintenance Agent (MA) and Key Process Area Agent (KPAA). In order to verify our proposed CMMI framework based on MAS architecture, a pilot study is conducted using a questionnaire survey. Rasch Model is used to analyze the pilot data. Item reliability is found to be poor and a few respondents and items are identified as misfits with distorted measurements

A systematic review of software development cost estimation studies

This paper aims to provide a basis for the improvement of software estimation research through a systematic review of previous work. The review identifies 304 software cost estimation papers in 76 journals and classifies the papers according to research topic, estimation approach, research approach, study context and data set. A web-based library of these cost estimation papers is provided to ease the identification of relevant estimation research results. The review results combined with other knowledge provide support for recommendations for future software cost estimation research, including: 1) Increase the breadth of the search for relevant studies, 2) Search manually for relevant papers within a carefully selected set of journals when completeness is essential, 3) Conduct more studies on estimation methods commonly used by the software industry, and, 4) Increase the awareness of how properties of the data sets impact the results when evaluating estimation methods

The Promise of Health Information Technology: Ensuring that Florida's Children Benefit

Substantial policy interest in supporting the adoption of Health Information Technology (HIT) by the public and private sectors over the last 5 -- 7 years, was spurred in particular by the release of multiple Institute of Medicine reports documenting the widespread occurrence of medical errors and poor quality of care (Institute of Medicine, 1999 & 2001). However, efforts to focus on issues unique to children's health have been left out of many of initiatives. The purpose of this report is to identify strategies that can be taken by public and private entities to promote the use of HIT among providers who serve children in Florida

IMPLEMENTING GROUP PRESENTATION USING POWERPOINT ( GPPPt ) TO IMPROVE THE STUDENTS’ SPEAKING COMPETENCE ( A Classroom Action Research at the Tenth Grade ( X-C ) , the Second Semester Students of SMA Negeri 1 Ngawi in 2009/2010 Academic Year )

Implementing Group Presentation Using PowerPoint ( GPPPt ) to Improve the Students’ Speaking Competence ( A Classroom Action Research at the Tenth Grade ( X-C ) , the Second Semester Students of SMA Negeri 1 Ngawi in 2009/2010 Academic Year ) . A Thesis: English Education Department, Graduate School, Sebelas Maret University, 2010. The objectives of this research are to: ( 1 ) identify whether or not and to what extent the use of “GPPPt” is able to improve the students’ speaking competence; and ( 2 ) describe the situations when GPPPt is being applied in the speaking class. In this research, the problem refers to the learning English, especially their speaking competence which is still low. The research methodology applied in this research is action research with two cycles in which each cycle starts from planning, acting, observing, and reflecting. The data collected are the qualitative data and the quantitative data. The qualitative data are collected from observation, interview, questionnaire, and document. The quantitative data are collected from the pre test in pre research and the post test in Cycle 1 and Cycle 2. The qualitative data are analyzed by Constant Comparative Method and the quantitative data are analyzed by descriptive statistics. The implementation of GPPPt has succeeded in improving and enhancing the students’ English speaking competence. It could be seen from these indicators: 1 ) it is able to: ( a ) help the students to express their mind and ideas quickly; ( b ) help the students make sentence ( s ) fluently; ( c ) improve the students’ pronunciation to be relatively accepted; ( d ) influence the students to use correct grammar to make sentence ( s ) ; and ( e ) increase the students’ achievement in speaking evaluation; and 2 ) it enables to: ( a ) reduce the students’ temptation to have a chat with their desk mates; ( b ) respond the teacher’s questions actively; ( c ) influence the students to avoid doing non academic activities; and ( d ) motivate the students to use either their dictionaries or grammar books in English class. Besides, from the collected data, the students had obtained better score from Cycle 1 to Cycle 2. For instance, the mean of pre test score of the pre research was 66.76, while the mean of the post test score in Cycle 1 was 74.00 and that of Cycle 2 was 77.64. That the implementation of GPPPt has succeeded in improving and enhancing the students’ English speaking competence, I would like to propose some suggestions for the English teachers, especially those who teach in senior high school to: ( 1 ) apply GPPPt to conduct the teaching learning process in the speaking class; ( 2 ) improve their acquisition of knowledge about GPPPt; and ( 3 ) provide more chance for the students to practice their English orally through GPPPt

The Men's Safer Sex (MenSS) trial: protocol for a pilot randomised controlled trial of an interactive digital intervention to increase condom use in men

Sexually transmitted infections (STI) are a major public health problem. Condoms provide effective protection but there are many barriers to use. Face-to-face health promotion interventions are resource-intensive and show mixed results. Interactive digital interventions may provide a suitable alternative, allowing private access to personally tailored behaviour change support. We have developed an interactive digital intervention (the Men's Safer Sex (MenSS) website) which aims to increase condom use in men. We describe the protocol for a pilot trial to assess the feasibility of a full-scale randomised controlled trial of the MenSS website in addition to usual sexual health clinical care

Effects of sustained communication time on reliability of JXTA-Overlay P2P platform: a comparison study for two fuzzy-based systems

Thus, it is important for each peer to have some number of neighbor peers. Moreover, it is more significant to discuss if each peer has reliable neighbor peers. In reality, each peer might be faulty or might send obsolete, even incorrect information to the other peers. We have implemented a P2P platform called JXTA-Orverlay, which defines a set of protocols that standardize how different devices may communicate and collaborate among them. JXTA-Overlay provides a set of basic functionalities, primitives, intended to be as complete as possible to satisfy the needs of most JXTA-based applications. In this paper, we present two fuzzy-based systems (called FPRS1 and FPRS2) to improve the reliability of JXTA-Overlay P2P platform. We make a comparison study between the fuzzy-based reliability systems. Comparing the complexity of FPRS1 and FPRS2, the FPRS2 is more complex than FPRS1. However, it considers also the sustained communication time which makes the platform more reliable.Peer ReviewedPostprint (author's final draft

Dynamic Learning Media to Improve the Pedagogic Experience in Conveying of SCM Course

Abstract This paper presents the application of free/open source software (FOSS) for developing educational in Supply Chain Management (SCM) course. There were abundant educational tools based F applications. However, lecturer still faces problems to implement such an learning media for impro the pedagogic experience i.e. customizing of software function, developing of a specific educat media, and illustrating of a SCM course content. The purpose of this research is to design dyn learning media for increasing efficiency in conveying subject matter of SCM course. We combin mobile and/or web devices with FOSS of web service to design dynamic learning media. It has a mo of real distribution problem in commodity paddy was captured. We design an interactive Web-based Mobile-based application by using WSDL, PHP and My SQL, and SOAP. The result of the resea Mobile & Web SCM application as dynamic learning media- will be able to improve the pedag experience to students.
