Československé expediční horolezkyně v běhu každodennosti od počátků tzv. normalizace do roku 1989 / Ordinary life of Czechoslovakian female mountain climbers during the period of so-called normalization till 1989

Kramářová, Barbora January 2015 (has links)
The thesis is devoted to the topic of ordinary life of women mountain climbers in the period of Czechoslovakian socialism (specifically between the years 1969 -1989). Through analysis and interpretationof oral historical interviews with women climbers who had participated in the national expeditions to foreign mountains, the author will reflect the following topics: how it could be possible to become a member of selective expedition team; how this "job" women climbers combined with a daily life, working duty, and its obligations in the family. The study will also focus on the issues of travelling, climbing topic as a prestigious international competition and presentation of this prestige by executive body; it will not stay aloof from the reflection of social or physical differences between Czechoslovakian climbers and other international teams and the intervention of the Communist Party in the composition of the expeditions. The work draw ordinariness of extraordinary fates of Czechoslovak women athletes - climbers nearer, and offers one of the possible approach to the relatively unexplored sector of Czechoslovakian sport.

“Jag vill vara barnmorska men inte till vilket pris som helst” : En kvalitativ studie om sex barnmorskors upplevelse av sin psykosociala arbetsmiljö inom förlossningsvården

Bäckemo, Erica, Larsson, Petra January 2022 (has links)
Förlossningskrisen beskrivs som en kris som eskalerat under 2021. Problematiken har däremot pågått under många år. Denna studie syftade till att undersöka barnmorskors upplevelse av den psykosociala arbetsmiljön inom förlossningsvården. Kvalitativ metod tillämpades. Studien genomfördes i Sverige. En respondent valdes ut genom ett bekvämlighetsurval och resterande fem via ett snöbollsurval. Semistrukturerade intervjuer tillämpades via videosamtal och insamlad data analyserades med hjälp av tematisk analys. Resultatet visade delvis i linje med tidigare forskning, att respondenterna upplevde sin psykosociala arbetsmiljö som påfrestande men meningsfull. Underbemanningen äventyrade patientsäkerheten och respondenternas möjlighet till att ge de stöd de önskade till patienterna begränsades. De främsta negativa faktorerna utöver underbemanningen var den höga graden av stress som respondenterna upplevde på arbetsplatsen, missnöjet kring att de tvingades arbeta treskift samt känslan av att de inte blev sedda. Stöd och gemenskap kollegorna emellan samt meningsfullheten i yrket beskrevs som bidragande faktorer till att respondenterna ville arbeta kvar inom förlossningsvården. / The maternity care crisis is described as a crisis that has escalated in 2021. Although the same issue has been ongoing for many years. This study aimed to examine midwives' experience of the psychosocial work environment within maternity care. Qualitative method was applied. The study was conducted in Sweden. The first respondent was selected through a convenience sample and the other five through a snowball sample. Semi-structured interviews were applied via video calls and the data were analysed using thematic analysis. The results showed partly in line with previous research, that midwives experienced their psychosocial work environment demanding but also meaningful. Understaffing compromised patient safety and limited respondents ability to provide the support they wanted to patients. In addition to understaffing, the main negative factors identified in the study were the high levels of stress experienced by respondents in the workplace, dissatisfaction with having to work three shifts and the feeling that they were not being seen. Support and community among colleagues and the meaningfulness of the profession were described as contributing factors to respondents' desire to remain working in maternity care

Safeguarding the health of mothers and children: American democracy and maternal and children's healthcare in America, 1917-1969

Traylor-Heard, Nancy Jane 10 August 2018 (has links)
This study examines major American maternal and children’s healthcare initiatives in the backdrop of international and national crises from 1917 to 1969. During these crises, maternal and child welfare reformers used the rhetoric of citizenship and democracy to garner support for new maternal and child healthcare policies at the national level. While the dissertation focuses on national policies, it also explores how state public health officials from Alabama, Mississippi, and New York implemented these programs and laws locally. The dissertation chapters study regional similarities and differences in maternal and child healthcare by highlighting how economy, culture, and politics influenced how national programs operated in different states. By utilizing White House Conference on Children and Youth Series sources, state public health records, and newspapers, this dissertation argues that by using rhetoric about protecting mothers, children, and American democracy, the Children’s Bureau (CB) members claimed and maintained control of maternal and child health care for over fifty years. CB leaders used World War I draft anxieties as a rallying call to reduce infant mortality and improve children’s health. In the following decades, maternal and children’s healthcare advocates met at the White House Conference on Children and Youth Series to discuss policies and influence legislation relating to maternal and child hygiene. The Sheppard-Towner Program, Title V or the Maternal and Children’s Health Section of the Social Security Act, and the Emergency Maternity and Infancy Care Program reflect policies debated at these White House conferences. By the 1950s, child welfare advocates associated mental health with a child’s overall health and the CB leaders and other child welfare reformers linked happy personalities to winning the Cold War. In the 1960s, the CB members and child welfare advocates’ attention shifted to focusing on low socio-economic mothers and children or children with intellectual disabilities. By 1969, the Children’s Bureau no longer managed national maternal and child healthcare programs and could not “safeguard the health of mothers and children.”

Post-Den Emergence Behavior and Den Detection of Polar Bears (<em>Ursus maritimus</em>) in Northern Alaska and the Southern Beaufort Sea

Robinson, Rusty Wade 01 March 2014 (has links) (PDF)
Pregnant polar bears (Ursus maritimus) construct maternal dens out of snow in the autumn where they give birth to and raise altricial young. In recent years, there has been a decrease in polar sea ice extent and thickness, which has led to changes in denning behavior. One such change in the southern Beaufort Sea (SBS) is that polar bears are selecting maternal den sites on land, rather than on unstable sea ice. This change, coupled with expanding petroleum exploration along Alaska's North Slope, heightens the likelihood of bear-human interactions at maternal den sites. The purpose of this research was to 1) describe polar bears' post-den emergence behavior, establishing a benchmark for comparison to identify behavioral changes associated with climate change and disturbance, and 2) explore factors influencing the efficacy of a currently used den detection method, forward-looking infrared (FLIR). Maternal den sites were observed along Alaska's North Slope from March to April of 2009 and 2010. The mean length of stay at den sites post-emergence was 11.3 ± 7.5 d. The mean date of den emergence was 14 March; abandonment 26 March. Adult females were generally inactive (58.4% out-of-den time) with standing being the most prevalent activity (49.9%). Cubs were generally active (76.7%), playing more than any other activity (45.3%). Bears spent the majority of their time in the den (97.3% for adult females and 99% for cubs) with short bouts of intermittent activity (× = 7 min 42 s). We documented the death of one member of a triplet polar bear litter at its den site. All three cubs showed low activity levels relative to other cubs observed, and one died within one week of den emergence. Necropsy confirmed that the dead cub had a low body weight and was malnourished. Capture later confirmed that the two surviving cubs were also undersized. Triplet litters are often smaller and suffer higher mortality rates than singletons and twins. This cub was not only a triplet but also born following 2 y of record minimum sea ice extent, both of which may have played a role in this cub's death. Concurrent with the den emergence portion of this work, we conducted a separate study to identify limitations and optimal conditions for locating dens using FLIR. We took handheld FLIR images of three artificial dens under varied conditions. We tested variables hypothesized to influence detectability with linear models using a zero-inflated negative binomial distribution. Solar radiation, wind speed, and den wall thickness reduced the likelihood of detecting dens. The negative effect of wind speed on detectability increased with increasing distance. To maximize the efficacy of hand-held FLIR, den surveys should be conducted when solar radiation is <16 w/m2 (night) and when wind speed is <10 km/h (6 mph). Adherence to these guidelines will maximize the protection FLIR can afford to denning bears.

Three Essays in Health Economics

Zhu, Huilin 08 1900 (has links)
This dissertation consists of three essays in health economics. The first chapter, "The Built Environment and Obesity in Philadelphia: The Use of Satellite Imagery and Transfer Learning," investigates the relationship between the built environment and health outcomes, specifically obesity prevalence in Philadelphia. The built environment can affect obesity prevalence through the physical activity environment and the food environment. The main innovation of this paper is to use a pre-trained convolutional neural network (CNN) to extract data representing the features of the built environment from high-resolution satellite imagery. Because of the lack of information on the food environment in satellite images, I combined a proxy variable for food access together with the feature variables to represent the characteristics of the built environment. I then employed the Elastic Net model to test the relationship between the feature variables of the built environment and obesity prevalence in Philadelphia. The results show that the built environment is highly associated with obesity prevalence. This study also provides some evidence that the features of the built environment that have been extracted from satellite imagery can reduce the role of food access in estimating obesity, as well as that adding these features can explain more variance of obesity. The second chapter, "Paid Maternity Leave and Child Health: Evidence from Urban China," uses the China Health and Nutrition Survey data to study whether the extension of paid maternity leave affects children's health outcomes in urban China. This paper uses the time variation of the implementation of a maternity leave policy across different provinces from 1987 to 1991 in China to estimate a two-way fixed-effects model. The results suggest that the expansion of paid maternity leave has no impact on children's health in urban China. The last chapter, titled "The Association between Paid Maternity Leave and Mothers' Health and Labor Outcomes in Urban China," studies whether the extension of paid maternity leave in 1987-1991 would affect the labor and health outcomes of mothers in urban China by using the China Health and Nutrition Survey data. Based on the variation in the implementation time of a paid maternity leave policy across different provinces, this paper employs a two-way fixed-effects model to estimate the policy impact on mothers' health and labor outcomes in China. The findings indicate that extending the duration of paid maternity leave is associated with an increased likelihood of mothers remaining employed after childbirth. However, the study also reveals a negative relationship between the extension of paid maternity leave and mothers' wage rates. / Economics

Ecology of northern long-eared bats (Myotis septentrionalis) in a coastal setting after the introduction of White-nose Syndrome

Gorman, Katherine M. 17 January 2023 (has links)
Northern long-eared bat (Myotis septentrionalis) populations have declined sharply in recent years due to the introduction and rapid spread of White-nose Syndrome. This has prompted an urgent need for a greater understanding of their natural history in order to support the conservation of extant populations, particularly where forested day-roost and foraging habitats are being fragmented by development. Prior to 2006, with other Myotis species on the endangered species list, northern long-eared bats were understudied. In recent years, with the pressing concern to document the ecology of all cave bats affected by White-nose Syndrome on the landscape, researchers have now prioritized northern long-eared bat habitat needs, day-roost use, social dynamics, and barriers to gene flow. A relatively new discovery has been the numerous coastal populations that occur in smaller forest patches often surrounded by anthropogenic development. The goal of my research is to aid in informing future monitoring and management protocols that are specific to northern long-eared bats, particularly as they may shift from Threatened to Endangered under the Endangered Species Act. The chapters of this dissertation explore (1) similarities and differences between coastal and more documented upland habitat associations for populations of northern long-eared bats throughout the summer months through the use of acoustic detectors; (2) relationships between acoustic activity patterns and weather on an hourly basis for several bat species on Long Island, New York; and (3–4) day-roost characteristics and social network dynamics of a coastal northern long-eared bat maternity colony on Long Island, New York. I found that northern long-eared bat colonies have larger spatial footprints in – and a moderate tolerance for – forests in anthropogenically-developed areas than previously believed, though many natural history aspects of the bat were similar among coastal and interior populations. Installation of artificial day-roost structures such as bat boxes would likely be used and highly beneficial to colonies in these conditions, particularly to offset the deleterious effects of stochastic disturbance events on day-roost availability and to support social cohesion (and, by extension, reproductive success) for coastal maternity colonies. Additionally, I found that acoustic activity increased in riparian areas, or at sites closer to water features, and as proportion of forest coverage increased at a broad scale. However, immediately around the detector this relationship was reversed. Taken together, this demonstrates that riparian corridors, water features, and forest structural heterogeneity should explicitly be included in management guidelines. / Doctor of Philosophy / White-nose Syndrome is a fungal disease that has killed millions of cave bats in North America, including the northern long-eared bat (Myotis septentrionalis) that during the spring through fall uses forests for roosting and foraging habitat. As the disease continues to spread, and as forests are increasingly being lost to urbanization, it is imperative for researchers and land managers to understand the landscape needs of this species so that they can retain those forests that are used by this species. In addition to broader landscape needs, it is important to understand what specific forest stand to tree features the bats are using, how their social dynamics support their reproductive success, and how to best support habitat conditions foster mating in the fall swarm to avoid inbreeding. In recent years, more northern long-eared bats have been documented in coastal landscapes, suggesting that these areas might be more important to the conservation of the species than previously believed. In this dissertation, my aim was to explore how or why the landscapes in these coastal areas were being used by these bats both during nightly foraging and during the day as resting areas (day-roosts). Additionally, I explored how multiple species of bats were responding to weather conditions on the coast across seasons. Overall, I found that complex forests continue to be an important resource for northern long-eared bats, as well as water features whereby the latter should be more explicitly included in conservation management plans. Northern long-eared bats also show an ability to successfully use small forest patches within a larger urbanized landscape, including using human structures for day-roosts. Human structures might provide reliable, multi-year day-roosts in areas where extreme coastal weather events (hurricanes) occur or increase or as natural processes reduce the suitability of these forests to provide day-roosts. These structures, particularly artificial roost boxes could also support the social network of reproductive northern long-eared bats and thus maintain population stability to some extent.

Day-roosting Social Ecology of the Northern Long-eared Bat (Myotis septentrionalis) and the Endangered Indiana Bat (Myotis sodalis)

Silvis, Alexander 08 December 2014 (has links)
Day-roost use by northern long-eared bat (Myotis septentrionalis) maternity colonies on the Fort Knox military reservation, Kentucky, USA, resulted in formation of non-random networks of roosts that exhibited a trend toward centralization. Centralization of day-roost networks was reflected in the social structure of colonies, which were characterized by dense associations among individuals within colonies. Social structure varied among colonies and appeared to be related to reproductive condition; colonies exhibited greater cohesiveness during parturition and lactation. Northern long-eared bat maternity colonies appeared to be exclusive, occupying distinct roosting areas with one or several areas receiving intense use. Day-roost removal simulations suggested a linear relationship between colony fragmentation and roost loss, and that loss of >20% of roosts is required to initiate colony fragmentation. Experimental hierarchical removal of day-roosts yielded results consistent with simulations, as removal of the single most-central (primary) roost had no impact on colony fragmentation, whereas removal of 24% of less-central (secondary) roosts resulted in partial network fragmentation. Patterns of colony day-roost and space use were similar pre- and post-removal treatments. Day-roost removal did not alter the number of roosts used by individual bats, but distances moved between roosts were greater in the secondary roost-removal treatment group. Day-roost characteristics largely were consistent pre-post treatment for both treatment groups. Historical data from an Indiana bat (Myotis sodalis) maternity colony revealed that this species also exhibits a non-random social assorting dynamic. Non-random social assortment resulted in a closely connected centralized network of day-roosts. Individuals within the Indiana bat maternity colony exhibited close social connections with colony members, but subgroups likely existed within the colony. Indiana bat day-roosting ecology appears flexible, as patterns of roost and space use differed substantially between years. Development of specific, but tactical, management approaches for individual colonies of both northern long-eared and Indiana bats may be possible. Such approaches would allow land managers to manage for both northern long-eared bat habitat and other objectives. However, the nature of targeted management approaches employed likely will depend on the unique forest context and dynamic within which individual colonies reside. / Ph. D.

Vaginal birth after caesarean section (VBAC): exploring women's perceptions

Meddings, Fiona S., MacVane Phipps, Fiona E., Haith-Cooper, Melanie, Haigh, Jacquelyn January 2007 (has links)
Yes / Aims and objectives.  This study was designed to complement local audit data by examining the lived experience of women who elected to attempt a vaginal birth following a previous caesarean delivery. The study sought to determine whether or not women were able to exercise informed choice and to explore how they made decisions about the method of delivery and how they interpreted their experiences following the birth. .  The rising operative birth rate in the UK concerns both obstetricians and midwives. Although the popular press has characterized birth by caesarean section as the socialites’ choice, in reality, maternal choice is only one factor in determining the method of birth. However, in considering the next delivery following a caesarean section, maternal choice may be a significant indicator. While accepted current UK practice favours vaginal birth after caesarean (VBAC) in line with the research evidence indicating reduced maternal morbidity, lower costs and satisfactory neonatal outcomes, Lavender et al. point out that partnership in choice has emerged as a key factor in the decision-making process over the past few decades. Chaung and Jenders explored the issue of choice in an earlier study and concluded that the best method of subsequent delivery, following a caesarean birth, is dependent on a woman's preference. Design and methodology.  Using a phenomenological approach enabled a holistic exploration of women's lived experiences of vaginal birth after the caesarean section. Results.  This was a qualitative study and, as such, the findings are not transferable to women in general. However, the results confirmed the importance of informed choice and raised some interesting issues meriting the further exploration. Conclusions.  Informed choice is the key to effective women-centred care. Women must have access to non-biased evidence-based information in order to engage in a collaborative partnership of equals with midwives and obstetricians. Relevance to clinical practice.  This study is relevant to clinical practice as it highlights the importance of informed choice and reminds practitioners that, for women, psycho-social implications may supersede their physical concerns about birth.
