Despite their growing complexity and increasing size, modern software applications must satisfy strict release requirements that impose short bug fixing and maintenance cycles, putting significant ...pressure on developers who are responsible for timely producing high-quality software. To reduce developers workload, repairing and healing techniques have been extensively investigated as solutions for efficiently repairing and maintaining software in the last few years. In particular, repairing solutions have been able to automatically produce useful fixes for several classes of bugs that might be present in software programs. A range of algorithms, techniques, and heuristics have been integrated, experimented, and studied, producing a heterogeneous and articulated research framework where automatic repair techniques are proliferating. This paper organizes the knowledge in the area by surveying a body of 108 papers about automatic software repair techniques, illustrating the algorithms and the approaches, comparing them on representative examples, and discussing the open challenges and the empirical evidence reported so far.
Closing the gap between research and practice requires that organizations can consistently incorporate new ideas and best practices. The Department of the Air Force (DAF) Integrated Resilience ...Directorate is leading a coordinated effort to increase the adoption of evidence-based violence prevention and resilience promotion programs across the entire Department. To support this effort, DAF is using Getting To Outcomes (GTO), an evidence-based implementation support that helps organizations plan, implement, and self-evaluate programs. Thus, the DAF is not only scaling up prevention programs but is also embarking on the largest scale-up of GTO to date. The study team trained personnel from every Air Force installation across the world to use GTO for their programs. Quantitative findings from training questionnaires and ratings of implementation plans as well as qualitative results from resilience personnel interviews suggest some lessons learned for scaling up implementation support. This study builds on established implementation science frameworks for scaling up interventions by identifying critical tasks and unique supports needed to scale up evidence-based prevention. Results suggest GTO helped DAF scale-up prevention across the Department, and that establishing leadership buy-in, simplifying evidence-based program selection and adaptation, monitoring implementation and outcomes, and creating dedicated prevention practitioner roles are critical tasks to support scale-up of evidence-based prevention. Unique supports needed to scale-up evidence-based prevention include multitiered learning systems; integrated tools that improve access to data and evolving evidence; prevention personnel with skills in program management, adaptation, and evaluation; timely crosscutting data; continuous learning to support sustainability; and leadership buy-in.

This article outlines the U.S. Army's effort to empirically validate and assess the Comprehensive Soldier Fitness (CSF) program. The empirical assessment includes four major components. First, the ...CSF scientific staff is currently conducting a longitudinal study to determine if the Master Resilience Training program and the Comprehensive Resilience Modules lead to lasting resilience development in soldiers. Second, the CSF program has partnered with other researchers to conduct a series of longitudinal studies examining the link between physiological, neurobiological, and psychological resilience factors. Third, the CSF program is also incorporating institutional-level data to determine if its material influences health, behavioral, and career outcomes. Fourth, group randomized trials are being conducted to ensure that resilience training incorporated under the CSF program is effective with soldiers. A specific rationale and methodologies are discussed.
When industrial and constructional renaissance started in the world, the great interest was going on towards the equipment’s, which was the first mean for production. After industry was settled the ...interest was going on towards the men ship which manpower on which the production depends. It was approved that it represents the basic part in all of the processes and the protection of those individuals against dangers of these equipment’s, industry and its accidents was the basic things which was studied in many researches until it crystallized in general principles for all industries and other take care in each industry. The professional safety is concerned as restrict which aims to take care of humanitarian and material principles also to raise the production of these principles, in the aspect of safety, health and providing the suitable healthy condition to the worker so he can feel safety, confidence and sociological settle, this will increase the production. So In order to maintain the manpower of business risks and to enable them to fulfill their role better to increase production and improve the quality and maintain the machine and supporting the national economy and keep pace with industrial developments and technological came the idea of research to focus on the importance of studying the subject of occupational safety by conducting a field survey to see the reality of professional safety in the relevant departments and work sites and through a questionnaire on the subject and conduct personal interviews with those concerned in this area and to prepare a program for the application of professional safety for each resource (labor, machines, materials, money) in construction sites and departments concerned.
Relatively little attention has been devoted to the social validation of potentially effective autism interventions. Thus, it is often difficult to identify and implement evidence-based practices, ...and programming is often inadequate. The authors identified autism intervention components with reported effectiveness for school settings. The results of a social validation survey completed by parents, teachers, and administrators indicate strong, consistent support for program components falling within five functional areas: (a) individualized programming, (b) data collection, (c) the use of empirically-based strategies, (d) active collaboration, and (e) a focus on long-term outcomes. These socially validated interventions can be used to evaluate existing autism curricula and develop training for professionals, parents, and students in order to improve public school autism programs.
•Uses national level data to analyze the impact of NREGS on household consumption.•NREGS increased rural household consumption expenditure between 6.5% and 10%.•NREGS increased rural marginalized ...caste household per capita consumption by 12%.•Impact of NREGS on household resource allocation among various consumption groups.
The Indian National Rural Employment Guarantee Scheme (NREGS) is one of the world's largest public works programs aimed at reducing poverty. NREGS guarantees up to a hundred days of employment in public works to rural households that demand work under the program. This is one of the first papers to analyze the impact of NREGS on household wellbeing by focusing on household consumption using national-level data. By focusing on consumption, I am able to assess whether and how household use the program to improve their living standards. I exploit the cross-district rollout of the program to analyze the causal effect on household consumption. Using the Consumption Expenditure Survey data from the National Sample Survey Organization, I conduct a difference-in-difference analysis where the treatment group consists of households in 184 early implementation districts and the control group consists of households in 209 late implementation districts. I find that the program significantly increased household per capita consumption between 6.5% and 10%. For the marginalized caste group, the program increased consumption by around 12%. Therefore, historical and ongoing discrimination along with other barriers to entry have not prevented this group from benefiting from the program. I further assess the impact on household budget allocation by focusing on various consumption categories. I find that households move toward the higher caloric and more nutritional items, like protein. Finally, for households with children there was significantly greater spending on “child goods” like milk, while in households without children spending on alcohol increased.
This study evaluated the effectiveness of an internet accessed training program that included Theory of Mind-based guidance, video models, visual supports, and virtual reality practice sessions in ...teaching appropriate job interview skills to individuals with high functioning Autism Spectrum Disorders. In a randomized study, twenty-two youth, ages 16–19, were evaluated during two employment interviews. Half received a training intervention following the initial interview and the half who served as a contrast group did not. Their performance pre and post intervention was assessed by four independent raters using a scale that included evaluation of both Content and Delivery. Results suggest that youth who completed the JobTIPS employment program demonstrated significantly more effective verbal content skills than those who did not.
