Feature Article—Continuing Education Module—International Water-Birth Practices With Recommendations During a Global Pandemic     

Barbara Harper 《The Journal of perinatal education》2021,30(3):128

The number of hospitals globally that offer water birth has increased exponentially during the past 10 years. This article examines some of the reasons for this increase as well as the objections to water birth by The American College of Obstetricians and Gynecologists, raised in their 2014 and 2016 opinion statements. The amount of research has also increased as more hospitals are keeping track of their data and publishing both prospective studies and retrospective analyses. The effects of water birth on the neonate are discussed through three meta-analyses from 2015, 2016, and 2018. The challenges and recommendations on continuing the use of water during labor and birth as a nonpharmacologic comfort measure even during a global pandemic are highlighted and supported by the best available evidence.  相似文献   

Postevent cues bias recognition performance in pigeons     

David N. Harper  Maryanne Garry 《Learning & behavior》2000,28(1):59-67

In the present study, we examined whether the presentation of postevent cues would bias recognition in a visual delayed matching-to-sample task with pigeons. Postevent cues were either consistent with the original target stimulus (i.e., they were the same as the correct choice option at recognition), inconsistent (i.e., they were the same as the incorrect recognition option), or neutral (i.e., they were different from both the correct and the incorrect recognition options). In Experiment 1, a single colored light served as the target stimulus. In Experiment 2, the target stimulus was one of three lights presented in a sequence. Both experiments demonstrated that recognition choices were biased toward the option corresponding to the postevent cue, but only if the cue occurred at the end of the delay interval. The present results mirror those found using the misinformation paradigm with human subjects.  相似文献

Climate control: United States weather modification in the cold war and beyond   总被引：1，自引：0，他引：1  

Harper KC 《Endeavour》2008,32(1):20-26

Rainmaking, hail busting, fog lifting, snowpack enhancing, lightning suppressing, hurricane snuffing...weather control. At the lunatic fringe of scientific discussion in the early twentieth century--and the subject of newspaper articles with tones ranging from skeptical titters to awestruck wonder--weather modification research became more serious after World War II. In the United States, the 'seeds' of silver iodide and dry ice purported to enhance rainfall and bust hailstorms soon became seeds of controversy from which sprouted attempts by federal, state and local government to control the controllers and exploit 'designer weather' for their own purposes.  相似文献   

Questionnaire mode effects in interactive information retrieval experiments     

Diane Kelly  David J. Harper  Brian Landau 《Information processing & management》2008

The questionnaire is an important technique for gathering data from subjects during interactive information retrieval (IR) experiments. Research in survey methodology, public opinion polling and psychology has demonstrated a number of response biases and behaviors that subjects exhibit when responding to questionnaires. Furthermore, research in human–computer interaction has demonstrated that subjects tend to inflate their ratings of systems when completing usability questionnaires. In this study we investigate the relationship between questionnaire mode and subjects’ responses to a usability questionnaire comprised of closed and open questions administered during an interactive IR experiment. Three questionnaire modes (pen-and-paper, electronic and interview) were explored with 51 subjects who used one of two information retrieval systems. Results showed that subjects’ quantitative evaluations of systems were significantly lower in the interview mode than in the electronic mode. With respect to open questions, subjects in the interview mode used significantly more words than subjects in the pen-and-paper or electronic modes to communicate their responses, and communicated a significantly higher number of response units, even though the total number of unique response units was roughly the same across condition. Finally, results showed that subjects in the pen-and-paper mode were the most efficient in communicating their responses to open questions. These results suggest that researchers should use the interview mode to elicit responses to closed questions from subjects and either pen-and-paper or electronic modes to elicit responses to open questions.  相似文献   

Acute adaptations and subsequent preservation of strength and speed measures following a Nordic hamstring curl intervention: a randomised controlled trial     

James Siddle  Matt Greig  Kristian Weaver  Richard Michael Page  Damian Harper 《Journal of sports sciences》2019,37(8):911-920

This randomised controlled trial investigated changes in eccentric hamstring strength, 10m sprint speed, and change-of-direction (COD) performance immediately post Nordic hamstring curl (NHC) intervention and following a 3-week detraining period.

Fourteen male team sports athletes were randomised to a do-as-usual control group (CG; n = 7) or to a NHC intervention group (NHC; n = 7). Isokinetic dynamometry at 180°/s evaluated eccentric hamstring strength immediately post-intervention as the primary outcome measure. Secondary outcomes included 10 m sprint time and COD. Each outcome was measured, pre, immediately post-intervention and following a 3-week detraining period.

Immediately post-intervention significant group differences were observed in the NHC group for eccentric hamstring strength (31.81 Nm^?1 vs. 6.44 Nm^?1, P = 0.001), COD (?0.12 s vs. 0.20 s; P = 0.003) and sprint (- 0.06 s vs. 0.05 s; P = 0.024) performance. Performance improvements were maintained following a detraining period for COD (?0.11 s vs. 0.20 s; P = 0.014) and sprint (?0.05 s vs. 0.03 s, P = 0.031) but not eccentric hamstring strength (15.67 Nm^?1 vs. 6.44 Nm^?1, P = 0.145) These findings have important implications for training programmes designed to reduce hamstring injury incidence, whilst enhancing physical qualities critical to sport.  相似文献   

A Qualitative Inquiry of the Counseling Dissertation Process     

Stephen V. Flynn  Christine L. Chasek  Irene F. Harper  Katherine M. Murphy  Maribeth F. Jorgensen 《Counselor Education & Supervision》2012,51(4):242-255

The authors in this consensual qualitative research study explored the dissertation experiences of 42 graduates (27 counselor educators, 13 counselors, 2 administrators) from 4 midwestern states. Identified domains included impact of environment, competing influences, personality traits, chair influence, committee function, and barriers to completion. An emergent theory reflected the interconnectedness of the dissertation process across internal, relational, and professional factors. Implications related to motivation, personal traits, and identification of barriers in the dissertation process are provided.  相似文献

Birth,Bath, and Beyond: The Science and Safety of Water Immersion During Labor and Birth     

Barbara Harper 《The Journal of perinatal education》2014,23(3):124-134

The 2014 objection to birth in water voiced by both the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists (ACOG) in ACOG Bulletin #594 on immersion in water during labor and birth is nothing new. The Committee on Fetus and Newborn published the very same opinion in 2005, based on a case report that was published in 2002 in the journal Pediatrics. What has changed since 2002 is a growing body of evidence that reports on the safety and efficacy of labor and birth in water. This article reviews the retrospective literature on water birth and explains newborn physiology and the protective mechanisms that prevent babies from breathing during a birth in water.  相似文献
