Toward a Multifaceted Heuristic of Digital Reading to Inform Assessment, Research, Practice, and Policy

In this commentary, the author explores the tension between almost 30 years of work that has embraced increasingly complex conceptions of digital reading and recent studies that risk oversimplifying digital reading as a singular entity analogous with reading text on a screen. The author begins by tracing a line of theoretical and empirical work that both informs and complicates our understanding of digital literacy and, more specifically, digital reading. Then, a heuristic is proposed to systematically organize, label, and define a multifaceted set of increasingly complex terms, concepts, and practices that characterize the spectrum of digital reading experiences. Research that informs this heuristic is used to illustrate how more precision in defining digital reading can promote greater clarity across research methods and advance a more systematic study of promising digital reading practices. Finally, the author discusses implications for assessment, research, practice, and policy

The relationship between diet and breast cancer in men (United States)

Objectives: The purpose of this paper was to investigate the relationship between food and beverage consumption and the development of breast cancer in men. Methods: Possible relationships of dietary factors to risk of breast cancer in men were assessed in a case-control study conducted between 1983 and 1986. Cases (N = 220) were ascertained from ten population-based cancer registries. Controls (N = 291) were selected by random-digit dialing (< age 65) and from Health Care Financing Administration Medicare beneficiary lists (? age 65). Results: No trends in risk were observed with increasing intakes of specific foods, except for an increase in risk with citrus fruits. No increase in risk with increasing amounts of specific fats, vitamins, or minerals or with amounts of protein, fiber, carbohydrate, starches, nitrites, or alcohol consumed was observed, except for an increase in risk with dietary vitamin C consumption. A decreasing trend in risk with dietary niacin and with coffee and an increasing trend in risk with tea consumption were observed. No associations were found with use of any dietary supplements, including vitamin C. Conclusions: The observed associations are not consistent with findings from studies of breast cancer in women and probably do not represent causal relationships. Dietary factors are unlikely to be strong determinants of breast cancer in men

Breastfeeding best start study: training midwives in a 'hands off' positioning and attachment intervention

The most common reasons cited by women for giving up breastfeeding early can be attributed to ineffective positioning and attachment and are therefore preventable. This study aimed to determine whether a 4-h training programme in 'hands off' positioning and attachment support increases midwives' knowledge and problem-solving skills. Using an unrelated comparison group and a pre- and post-intervention design, 108 midwives (experimental group) completed a 4-h standard breastfeeding training workshop focusing on effective positioning and attachment and the use of hands-off teaching methods. Knowledge and problem-solving skills were assessed using a modified form of the previously validated Breastfeeding Support Skills Tool. Pre- and post-training scores were compared with those of 27 student midwives (control group) who undertook the same assessments but without the breastfeeding training. Baseline knowledge scores of the midwives and the student midwives did not differ significantly (average difference 0.7 points to qualified midwives' advantage, 95% CI = -3.4 to 1.9). Following training, the qualified midwives' total scores increased significantly (7.2 points, +95% CI = 6.2-8.2). Minimal changes (1.4 points, 95% CI = -0.15 to 2.9) in students' scores were found. The additional increase owing to training above that which might be expected due to practice (i.e. the average difference in change scores between the two groups) was 5.8 points (95% CI = 3.75-7.96), representing a large effect size for the training (d = 0.95). There is a large variation in the breastfeeding knowledge of midwives working in post-natal care and, on average, they are no more skilled than senior student midwives. The study has shown that a 4-h workshop in a positioning and attachment intervention, using a 'hands-off' approach, can increase midwives' knowledge of breastfeeding support relevant to the immediate post-natal period. It is applicable to all midwives, and could be a cost-effective way of improving the ability of mothers to begin and continue to breastfeed successfully
