This paper will examine how the settings in which midwives practice (the birthplace) and models of care affect midwives’ decision making during the management of labour. One-hundred-and-four independent, team and hospital based midwives and 100 low obstetric risk nulliparous women to whom labour care was provided were surveyed. These midwives and women resided in the Auckland metropolitan area of New Zealand. The majority of midwives who participated worked in models of care which provided women with continuity of carer and care, however, this was not found to influence the way the midwives provided labour care. Instead, practice was found to be relatively homogenous regardless of whether the midwives worked in independent, team, or hospital-based practice. The birthplace setting in which the labour care took place did influence midwifery practice. The majority of midwives provided labour care in large obstetric hospitals and identified practices dominated by the medical model of care. Practice was described as being influenced by intervention and the need for technology, however, this did not prevent the majority of women from perceiving they were actively involved in the decision making process and that they worked in partnership with their midwives. Closer examination of the midwives’ decision making processes whilst providing the labour care revealed that the midwives’ individual decisions were influenced by the needs of the women rather than the hospital protocols. What became evident was that the midwives in this study had adopted a humanistic approach to care whereby technology was used alongside relationship-centred care.  相似文献

Older lesbians face the triple jeopardy of ageism, sexism, and heterosexism, and their experiences are largely invisible. This qualitative, exploratory study examines the formal and informal caregiving experiences of 20 lesbians, 65 and older, who had utilized home care services due to acute illness or chronic disabilities. Half of those not partnered reported some level of isolation from support networks. Nearly all study participants eventually found home care workers with whom they were satisfied and even quite connected. Practice implications are discussed in context of study participants’ views of how being lesbian affects their aging process and day-to-day lives.  相似文献

Although there are high rates of sexual problems and sexual dysfunction in adulthood (Mitchell et al., 2013), little is known about the circumstances under which problems are first experienced. A growing body of research addresses prevalence of problems in sexual functioning among adolescents and young adults, yet little is known about the meanings that young people give to these experiences or how they deal with them. We used content analysis of qualitative interviews with 53 heterosexual, sexually active Canadian adolescents (ages 18 to 21) to explore their perceptions of the sexual problems in functioning they had experienced and the strategies (if any) they used to address them over time. Problems among most young people originated early in their partnered sexual life. Figuring it out emerged as an intentional process directed toward improving sexual experiences, although certainly not all young people were successful. Strategies for figuring it out included informational or material help seeking, experimentation to inform future actions, mutual sharing and problem solving, and building emotional connection to improve sexual functioning. Implications for understanding the development of sexual dysfunctions in adulthood are discussed.  相似文献

This study sought to provide information about the sexual well‐being of 298 mixed‐sex couples seeking relationship therapy and determined the extent to which problems with sexual functioning and dyadic adjustment of both partners are associated with sexual satisfaction. Partners completed measures of dyadic adjustment, sexual satisfaction, and sexual functioning. Thirty percent of couples reported a clinically significant sexual problem. Compared to their male partners, the women were more likely to report a sexual problem as well as lower dyadic adjustment, sexual satisfaction, and overall sexual functioning. Path analysis indicated that relationship adjustment uniquely predicted individuals' own sexual satisfaction; problems in sexual functioning uniquely predicted own and partner sexual satisfaction. Findings underscore the need to address sexual problems in relationship therapy.  相似文献

Although Canadian policies support "aging in place," there still will be a number of older adults who will require institutional care in the future. Most research on elder abuse, however, has focused on domestic abuse and has paid less attention to institutional abuse. The purpose of this article is to comprehensively review current research to identify gaps in knowledge and methodological issues in the study of institutional abuse. Overall, 49 studies in English and 20 studies in French were reviewed, and 11 key-informant interviews were conducted with methodological experts. Methodological challenges are addressed in light of the review and interviews.  相似文献

We examined the association of joint trajectories of ethnic identity and criminal offending to psychosocial maturity, gang membership, and Mexican American affiliation among 300 Mexican American male juvenile offenders from ages 14 to 22. There were two low‐offending groups: one was the highest in ethnic identity and changing slightly with age and the other was the lowest in ethnic identity and stable with age. A third group displayed moderately declining offending and moderately stable ethnic identity. A fourth group displayed high‐offending individuals with moderate, but increasing, levels of ethnic identity, who were initially lower in psychosocial maturity and more likely to be gang members. The findings highlight the need to contextualize theories of ethnic identity development.  相似文献

Contemporary electronic industry offers a wide range of products. Usually touch sensitive and with few buttons and a lot of functions these products not always have a friendly interface. The human x design interface based on electronics' ergonomics is the focus of this research. An evolutionary analysis of the electronics industry design within a contemporary context clarifies this relation and proposes new guidelines for a more conscious design.  相似文献

Ergonomic sleep studies benefit from long-term monitoring in the home environment to cope with daily variations and habituation effects. Polysomnography allows to asses sleep accurately, but is costly, time-consuming and possibly disturbing for the sleeper. Actigraphy is cheap and user friendly, but for many studies lacks accuracy and detailed information. This proof-of-concept study investigates Least-Squares Support Vector Machines as a tool for automatic sleep stage classification (Wake-N1-Rem to N2-N3 separation), using automatic trainingset-specific filtered features as derived from three easy to register signals, namely heart rate, breathing rate and movement. The algorithms are trained and validated using 20 nights out of a 600 night database from over 100 different healthy persons. Different training and test set strategies were analyzed leading to different results. The more person-specific the training nights to the test nights, the better the classification accuracy as validated against the hypnograms scored by experts from the full polysomnograms. In the limit of complete person-specific training, the accuracy of the algorithm on the test set reached 94%. This means that this algorithm could serve its use in long-term monitoring sleep studies in the home environment, especially when prior person-specific polysomnographic training is performed.  相似文献
