Worse Than Spam: Issues In Sampling Software Developers

Background: Reaching out to professional software developers is a crucial part of empirical software engineering research. One important method to investigate the state of practice is survey research. As drawing a random sample of professional software developers for a survey is rarely possible, researchers rely on various sampling strategies. Objective: In this paper, we report on our experience with different sampling strategies we employed, highlight ethical issues, and motivate the need to maintain a collection of key demographics about software developers to ease the assessment of the external validity of studies. Method: Our report is based on data from two studies we conducted in the past. Results: Contacting developers over public media proved to be the most effective and efficient sampling strategy. However, we not only describe the perspective of researchers who are interested in reaching goals like a large number of participants or a high response rate, but we also shed light onto ethical implications of different sampling strategies. We present one specific ethical guideline and point to debates in other research communities to start a discussion in the software engineering research community about which sampling strategies should be considered ethical.Comment: 6 pages, 2 figures, Proceedings of the 2016 ACM/IEEE International Symposium on Empirical Software Engineering and Measurement (ESEM 2016), ACM, 201

Perceptions Held by Obese Children and their Parents: Implications for Weight Control Intervention

The study was designed to identify some of the psychosocial barriers to compliance in a hospital-based weight control intervention program for adolescents. Forty obese adolescents, 10 to 16 years of age, and their parents were surveyed prior to participa tion in a behavioral change weight control program at a major teaching hospital. Significant correlations were obtained between weight loss outcome and six factors. In obese adolescents, weight loss was significantly associated with their beliefs regarding: (1) personal control over weight, (2) barriers or difficulty of losing weight, (3) medical problems as a cause of their obesity, (4) family problems as a cause of their obesity, and (5) perceived willingness of family members to diet. It is suggested that greater weight loss in children who perceived more barriers/difficulty and less family willing ness to diet may reflect the importance of having realistic expectations related to be havioral compliance. In addition, a positive parental attitude or expectation that the child was less likely to be overweight in the future was associated with greater weight loss compliance. Other parental health beliefs, however, did not generally predict the child's weight loss response to the intervention. The findings lend support to the sig nificance of the adolescent's beliefs regarding weight and family support in explaining weight loss response to a behavioral change intervention program.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/66720/2/10.1177_109019818801500204.pd

Impact of spouse caregiving on health behaviors and physical and mental health status

The impact of caring for a spouse with a progressive dementia on caregiver's health behaviors and health status was examined. Data collected from 44 spouse caregivers indicates that: • Providing full-time care interferes with preventive health behaviors (eating nutritiously, exercising) and contributes to high risk behaviors (overeating, alcohol and substance use); • Health behaviors are frequently used as coping strategies; • Caregivers rated their own health as poorer than their spouse's health; and • Disabling (arthritis, cardiac and back problems) and stress-related health problems (migraines, colitis) are a consequence of and interfere with care provision.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68204/2/10.1177_153331759400900105.pd

Population issues and social indicators of well-being

Relating demographers' measures of various population characteristics (size, growth/decline, density, age/sex structures, migration, et cetera) to measures of well-being recently developed within the social indicators movement promises to provide new knowledge about the linkage of population and well-being that can enhance decision making about important population issues.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43515/1/11111_2005_Article_BF01363887.pd
