Nonsuicidal self‐injury (NSSI) is a maladaptive coping strategy that is of significant clinical concern for behavioral health professionals in college settings. Relationships between NSSI, acquired capability for suicide, interpersonal cognitions, and five‐factor model personality traits were assessed in a survey‐based study that included 192 young adults in a college setting. Results indicated that those with an affirmative suicide attempt history, greater acquired capability for suicide, and elevated neuroticism had an increased likelihood of lifetime NSSI.  相似文献

Issues surrounding cesarean birth are of interest to researchers from varied disciplines and nations. In this column, three studies that examine aspects of cesarean birth are reviewed. One study presented a review of 11 studies and found differences in the perceptions of white and minority mothers toward labor, vaginal birth, and cesarean birth. In a second study on infant outcomes, Japanese researchers found differences in transient tachypnea in infants born in the first half of the 37th week gestation and those born in the second half of the 37th week and the 38th week of gestation. In a third study conducted in Norway, researchers found more complications when cesarean birth occurred at advanced dilation. The three studies' implications for childbirth educators are discussed.  相似文献

Two and a half years after the initial funding allocation for teacher release hours to establish Support Teacher positions in New Zealand schools, 63 (91%) of the schools with a Support Teacher funding allocation completed a questionnaire on the establishment of the position in the school. Information derived from the questionnaire included qualifications and experience of teachers appointed to the role of Support Teacher, and detail regarding the establishment, practice, and degree of adherence to the Support Team model of operation. Significant difficulties with Support Team establishment and program adherence are reported, notably in selection, training, organizational support, and form of service delivery. The results are discussed in terms of the speed of drift from the model, differences between primary and secondary schools in implementation of the program, the importance of training, and the presence of an active Support Team Management Committee in ensuring effective service delivery.  相似文献

The Discrepancy Hypothesis posits that childrenearly in the acquisition process read visually(holistically) and spell phonologically. Thisclaim was examined and rejected. Weinvestigated reading and spelling in Grade 1and Grade 2 children using controlled nonwordand word materials with a variety oforthographic patterns. While reading andspelling were strongly correlated even amongthe younger readers, discrepancies betweenperformance levels occurred in both directions. Children's responses were affected by wordcharacteristics and whether or not theyreceived school phonics instruction. Phonologically complex words, such as thosecontaining consonant clusters, wereparticularly difficult for Grade 1 children toread, while words that were difficult to spellcorrectly but not to read tended to havemultivalent mappings from sound to spelling.The generation of reading responses tospecially selected nonwords was affected byboth implicit and explicit phonological sourcesof knowledge. Orthographic knowledge gained inspelling did not always transfer to reading,and vice versa.  相似文献

Many developing countries are investing in large-scale initiatives to deploy information and communications technology in schools. However, merely equipping schools with hardware and software does not guarantee that the technology is used effectively to improve learning outcomes. This study aims to identify factors that influence the use of technology in schools in a developing-country context. It investigates this through a multiple-case study of the Australian AID tablet computer programme in the Philippines, in which 1000 tablets were given to nine public schools for student use. Focusing specifically on the impact at a whole-school level, the study revealed factors affecting outcomes that were specific to a developing-country context, as well as confirming the relevance of more general factors identified in the literature. The study also brings to light tablet-specific benefits and issues in this context. These results have implications for the effective school-level implementation of technology programmes in developing countries. Recommendations that proceed from these are presented for policy-makers and school administrators looking to use these devices in schools.  相似文献

IN THIS COLUMN, THE AUTHOR REVIEWS RESEARCH ON FOUR SEPARATE TOPICS: the prevention of preterm birth, the effect of epidurals on breastfeeding success, the possible protective effect of lactation on breast cancer, and laboring in water. In two separate studies-a multisite study in the United States and a second study from Brazil-natural progesterone was shown to significantly reduce the incidence of preterm birth in women at high risk. A third study conducted in the United Kingdom examined the effect of clindamycin on preventing infection that can lead to preterm birth. A group of studies related to lactation found that early breastfeeding was more successful in women who did not have epidural anesthesia. In a Korean study, the lifetime duration of breastfeeding was associated with a significant reduction in breast cancer. Concerning waterbirth, Swiss researchers found that, when a woman labored in water, she regulated both water temperature and bathing duration to ensure that her body temperature and that of the fetus remained within a normal physiological range.  相似文献

Making the transition to formal proof   总被引:1,自引:0,他引:1  
This study examined the cognitive difficulties that university students experience in learning to do formal mathematical proofs. Two preliminary studies and the main study were conducted in undergraduate mathematics courses at the University of Georgia in 1989. The students in these courses were majoring in mathematics or mathematics education. The data were collected primarily through daily nonparticipant observation of class, tutorial sessions with the students, and interviews with the professor and the students. An inductive analysis of the data revealed three major sources of the students' difficulties: (a) concept understanding, (b) mathematical language and notation, and (c) getting started on a proof. Also, the students' perceptions of mathematics and proof influenced their proof writing. Their difficulties with concept understanding are discussed in terms of a concept-understanding scheme involving concept definitions, concept images, and concept usage. The other major sources of difficulty are discussed in relation to this scheme.This article is based on the author's doctoral dissertation completed in 1990 at the University of Georgia under the direction of Jeremy Kilpatrick.  相似文献
