Memory leaks in software have proved to be widespread in C programs. Much research has been done to analyze and detect memory leaks statically. However, due to the complexity and variety of memory leak vulnerabilities, it is difficult to propose a static method that can detect all kinds of memory leaks. In this paper, we propose a method to investigate the applicability of static analysis tools to detect various kinds of memory leaks. We first divide memory leak vulnerabilities into 11 categories, from the perspectives of heap memory behaviors and program structures. According to this classification, we design and implement a pattern-based system to generate a program dataset named HPMD (Heap program Memory Dataset) that contains a variety of memory leaks. Experiments on open source repositories show that compared with existing datasets, HPMD can evaluate current tools in terms of their ability to detect various kinds of memory leaks, and can recommend reasonable tools given a specific program.
In schools, band is often seen as a class where students and teachers can be creative. But is this true? Many schools use a traditional band model, which may not allow space for creative activities. This article, insp...

This paper reports on curriculum and course structure development, a pilot program to address the needs of entry point for adult students into the tertiary studies in Iceland. With the new program structure, we seek to appeal to older students, working people who missed their opportunity to go to university as young adults for various reasons. Also, we seek to appeal to young adults that wish to attend a shorter university program, 90 ECTS with the option of continue to a full ***. Degree later.

Objective: Some have hypothesized that community college programs are not sufficiently structured to support student success and that students would benefit from more highly structured programs. This study examines the specific ways that structure is expressed in policy and practice at representative community colleges. Method: Using data obtained from interviews and program websites at Washington State community and technical colleges, we examine the structure of community college career-technical programs along four dimensions: program prescription, program alignment, access to information, and active advising and support. Results: We find high levels of structure on all dimensions in the allied health, computer and information science, and mechanics and repair programs. There are moderate levels of structure in the business and marketing programs. Contributions: This study documents the specific ways that community college career-technical programs are structured to support student success, and it provides a framework for examining structure to inform practice and guide future research efforts.

School-based peer programs have been shown to foster positive youth development, school connectedness, and academic achievement. They provide a wide range of social and academic support services for students, while addressing topics related to inclusion, mental health, substance use, bullying, cultural competency, conflict resolution, and study skills. Despite this positive potential, studies indicate that some peer programs can have a neutral or even a negative impact on mentees. Given the conflicting findings, this study sought to understand why certain programs are more successful than others. Using a sequential mixed-methods approach, this study addressed the following research questions: • What do peer program professionals identify as program strengths at their respective schools, and what factors do they identify as contributing to these program strengths? • What do peer program professionals identify as challenges to the effective implementation of peer programs at their respective schools? • What attempts to address these challenges have peer program professionals found to be effective? To what do they attribute their effectiveness? Analysis of 13 expert interviews and 623 survey respondents revealed a variety of peer program benefits as well as key challenges affecting successful program implementation. Some of the strengths included easing school transitions, developing student leadership skills, increasing school connectedness, improving peer relations, and providing valuable academic and social/emotional services. Some of the challenges included insufficient time for program coordinators to plan, supervise, and evaluate their respective programs, difficulty with getting student leaders to follow through on their responsibilities, alternative programs competing for student interest, and insufficient time for consistent meetings between student leaders and mentees. Recommendations for practice consist of schools and districts: (a) giving full support to t
