Bond and Archibald (2003) suggest that in southern African savannas there is a complex interplay between fire frequency and herbivory medicine 4212 . Heavily grazed savannas support short grass "lawns" treatment vitamin d deficiency , dominated by species in the sub-family Chloridioideae symptoms 8dpiui , which do not burn medicine 93832 . These lawns support a diversity of large grazers including white rhino (Ceratotherium simum), wildebeest (Connochaetes spp. Under less intense grazing, these lawns can switch to supporting bunch grass, in the subfamily Andropogoneae, which support a less diverse mammal assemblage adapted to gazing tall grasses, such as African buffalo (Syncerus caffer). Bond and Archibald (2003) suggest that intense grazing by African mammals may render savannas less flammable by creating mosaics of lawns that increase the diversity of the large mammal assemblage. Large frequent fires are thought to switch the savannas to more flammable, tall grasses with a lower diversity of large mammals. Bond and Archibald (2003) propose a model where frequent large fires can result in a loss of lawns from a landscape with corresponding declines in mammal diversity. The mechanism for this is that resprouting by grasses following fire causes a lowering in overall grazing pressure across the landscape. Fully understanding the drivers of the expansion of woody vegetation into rangelands, including the role of fire and herbivory, remains a major ecological challenge (see ag. The production of large quantities of fine and well-aerated fuels may have greatly increased the frequency of landscape fire disadvantaging woody plants and promoting further grassland expansion. The monsoon climate is particularly fire-prone because of the characteristic alternation of wet and dry seasons. The wet season allows rapid accumulation of grass fuels, while the dry season allows these fuels to dry out and become highly flammable. Furthermore, the dry season tends to be concluded by intense convective storm activity that produces high densities of lightning strikes (Bowman 2005). Indeed, humans can be truly described as a fire keystone species given our dependence on fire; there is no known culture that does not rou- tinely use fire. For example, the Tasmanian Aborigines always carried fire with them, as it was an indispensable tool to survive the cold wet environment (Bowman 1998). The expansion of humans throughout the world must have significantly changed the pattern of landscape burning by either intentionally setting fire to forests to clear them or accidentally starting fires. How prehistoric human fire usage changed landscape fire activity and ecosystem processes remains controversial and this issue has become entangled in a larger debate about the relative importance of humans vs. Central to this debate is the Aboriginal colonization of Australia that occurred some 40 000 years ago. Some researchers believe that human colonization caused such substantial changes to fire regimes and vegetation distribution patterns that the marsupial megafauna were driven to extinction. This idea has recently been supported by the analysis of stable carbon isotopes (d13C) in fossil eggshells of emus and the extinct giant flightless bird Genyornis newtoni in the Lake Eyre Basin of central Australia. Further, climate modeling suggests that the switch from high to low leafarea-index vegetation may explain the weak penetration of the Australian summer monsoon in the present, relative to previous periods with similar climates (known as "interglacials") (Miller et al. Yet despite the above evidence for catastrophic impacts following human colonization of Australia, it is widely accepted that at the time of European colonization Aboriginal fire management was skilful and maintained stable vegetation patterns (Bowman 1998). For example, recent studies in the savannas of Arnhem Land, northern Australia, show that areas under Aboriginal fire management are burnt in patches to increase kangaroo densities (Figure 9. Further, there is evidence that the cessation of Aboriginal fire management in the savannas has resulted in an increase in flammable grass biomass and associated high levels of fire activity consistent with a "grass­fire cycle" (see Box 9. It is unrealistic to assume that there should only be one uniform ecological impact from indigenous fire usage. Clearly working out how indigenous people have influenced landscapes demands numerous studies, in order to detect local-scale effects and understand the underlying "logic" of their landscape burning practices. Also of prime importance is study of the consequences of prehistoric human colonization of islands such as New Zealand. In this case, there is clear evidence of dramatic loss of forest cover and replacement with grasslands (McGlone 2001).

She uses a walker to ambulate and has the facility administer her medications to her medications 6 rights . While conducting beginning of shift rounds treatment 4 high blood pressure , a direct care staff member heard yelling coming from Mrs medicine 513 . The direct care staff member called for assistance prior to kneeling down beside Mrs. She stated that her right hip and lower buttock was aching but that she thought she was okay. Amok explained that she was holding onto the bed and reached to get her throw pillows to finish making her bed. What preventative measures could the previous shift direct care staff members have taken to prevent this fall from occurring? This chapter will also discuss using least restrictive methods when working with residents with the goal of having not only no physical restraints, but no chemical restraints as well. Students should obtain a good understanding of the negative outcomes that a resident may experience resulting from restraint use, as well as how to minimize those consequences. Be able to describe potential negative outcomes of restraint use and the care practices necessary to minimize those negative outcomes d. Be able to discuss proper monitoring techniques for physical and chemical restraints. Be able to describe techniques that can be used as an alternative to restraint use f. Be able to identify the roles of the resident, family, physician and caregiver, in making the decision to use restraints 2.

Typically used for residents that may lean too far forward and fall out of the wheelchair. Considered a restraint if the resident cannot disengage the latch on the seatbelt independently. Typically used for residents that may self-harm either intentionally or unintentionally. Considered a restraint when it reduces the ability for the resident to do daily 672 tasks independently such as opening a door or using the bathroom. Geri-chair Instructor Notes: It is important to note that a key point in determining whether something is a restraint is whether it restricts movement. For example, a side rail is not a restraint for residents who use the rail to help them sit up in bed and who can exit the bed by going around the rail or by going out the other side of the bed. On the other hand, the side rail is a restraint if it confines a resident to the bed.

Professional and family caregivers treatment of hyperkalemia , as well as members of the community-at-large medicine 600 mg , all have a role in providing opportunities for meaningful aging to residents medications while pregnant . The changes that we have talked about in this chapter present challenges for older adults in their daily lives treatment zap . Being sensitive to these challenges helps you understand how older adults are experiencing their lives. Instructor Notes: the purpose of this activity is to provide an experiential learning exercise to help students understand what the day-to-day routine may be for an older adult or adult with disability. When everyone is finished, bring the group together and start a discussion on their experiences. Materials needed: Sunglasses, with lens smeared with Vaseline 2 pairs yard gloves (thick, heavy kind) 3 pairs ear plugs or cotton balls Sugar packets and cups Toothpaste Newspaper the amount of materials depends on the class size. Student #2 will give him or her a sugar packet and ask him or her to open it and put it in the cup. Student #2 will give him or her a tube of toothpaste and ask him or her to open it. What did it feel like to be the older adult with a hearing, visual, or dexterity impairment? What did it feel like to watch the person with an impairment try to accomplish his or her task? For example, if an older adult is having trouble opening sugar packets, instead of opening the sugar packets for them all the time, what about finding another way to dispense sugar that she could more easily use, like a sugar container on the table? Urinary incontinence (leaking urine) affects only 10% of older adults, mostly women. What it takes to learn (amount of time, level of concentration) changes with age, and older people must learn to work at their own pace, practice new skills, and avoid competitive situations that favor youthful quickness. Older adults are quite skilled at integrating knowledge and skills acquired over the lifetime. Older adults should have decisions made for them because they are incapable of making them alone. Older adults with dementia may lose the ability to make certain decisions and this is determined by a doctor. When we make 191 decisions for an older person this is called paternalism, which means we are treating them like children. The average older adult is either uninterested in or physically unable to participate in sexual activity. A decrease in sexual activity is frequently due to medication or the loss of a partner. Although older people may be more likely to experience certain health conditions, not all older people are sick. For each of these systems, name one change related to aging and how this change might affect an older adult: a. Circulatory Changes in the circulatory system as we age: o In general, the flow of blood changes. Digestive Changes in the digestive system as we age: o Stomach cannot hold as much food. Respiratory Changes in the respiratory system as we age: o Older adults do not take in oxygen or breathe out carbon dioxide as well. Skeletomuscular Changes in the skeletomuscular system as we age: o the spine may change- it may become shorter or more curved. Endocrine Changes in the endocrine system as we age 195 o the amount of hormones produced may change and the body may become less sensitive to the effect of hormones. As we get older, we may become more resistant to insulin, which keeps the body from turning glucose into energy. Urinary Changes in the urinary system as we age: o Bladder muscles weaker and stretched. Integumentary Changes in the skin, hair, and nails as we age: o Fat under the skin moves around so that there is less fat in some places and more in others.

For instance withdrawal symptoms , the name "ApaLongor" means "the man with a bull with a brownish coat colour" medicine 19th century . The favourite breeding bull receives many privileges from the owner such as being adorned with a bell medications on airline flights , or prompt treatment when ill medications safe during pregnancy . The world should appreciate the role pastoralists play in sustainably utilizing their uniquely adapted breeds. Not only do these animals provide food and income security for their keepers, but they also contribute to the maintenance of genetic diversity, thereby providing a resource for future genetic improvement programmes. In this regard, pastoralists need appropriate support from livestock services provided by national governments, civil society organizations and the international community. For further information see: Loquang (2003); Loquang (2006a); Loquang (2006b); Loquang and Kцhler-Rollefson (2005). For the low-input system, it is inadequate to think of genetic improvement only in terms of increases in output traits, such as body weight, milk or egg production, or fleece weight. Unfortunately, very little is known about the genetic improvement of intrinsic efficiency. Similarly, it is a taboo for cattle to deliver twins whether at the first or subsequent delivery. Any such situations (births of twins) would lead to the animals concerned being slaughtered by stoning or beating. An animal in this situation is said to have become a witch and as such should be promptly eliminated! This does not mean that the animal needs less feed to achieve a given level of performance. For example, in contrast to the ratio of weight gain/feed intake, residual feed consumption is relatively independent of growth. Their herds contribute a substantial proportion of national cattle exports, particularly to the large markets of Nigeria where Bororo animals sell at a premium. WoDaaBe herders exploit a semi-arid territory characterized by erratic and unpredictable rainfall. In an ordinary year, fresh grass is available for only two to three months at any given location. Access to forage, water and services requires a degree of purchasing power and negotiation with neighbouring economic actors competing for these resources. It has been proposed that the concept of "reliability" is key to understanding the management strategies of pastoralists under such conditions (Roe et al. In these systems, breeding has to be closely interconnected with the environment and the production strategy. The main goal of the WoDaaBe is to maximize the health and reproductive capacity of the herd throughout the year. This involves specialized labour, focusing on managing the diversity and variability of both grazing resources and livestock capabilities. The Bororo Zebu of the WoDaaBe in Niger ­ selection for reliability in an extreme environment the nutritional value of the range is maximized by moving the herd across zones that show spatially and temporally heterogeneous distribution of fodder. While feeding capacity has in part a genetic base (for example the enzymatic system or the size and conformation of the mouth), it can also be greatly affected by learning, based on individual experience and imitation between social partners (for example efficient trekking and grazing behaviour and diet preferences). A carefully diversified diet of grasses and browse is favoured, in order to correct nutritional imbalances which, particularly during the dry season, could keep feeding motivation low by triggering negative digestive feedback. With the onset of the dry season, while other pastoral groups sharing the same ecosystem move closer to water points, where water is more accessible but pasture is poor, the WoDaaBe move in the opposite direction, trying to keep their camps close to prime fodder. This results in longdistance mobility and a watering regime which, at the peak of the hot season, often involves journeys of 25­30 kilometres to reach the well, with the herd drinking every third day. Consequently, their breeding system focuses on fostering social organization and interaction within the herd. Breeding involves selective mating of cows with matched sires, and a marketing policy that targets unproductive cows. Close monitoring of the herd allows early detection of oestrus and ensures that more than 95 percent of births result from matchmaking with selected males. A different sire is used for almost every oestrus of a particular cow, with an overall ratio of about one sire every four births. Sire borrowing remains frequent (affecting about half the births) even when a breeder owns pedigree sires of his own.

Many policies and technologies to reduce greenhouse gas emissions are associated with health co-benefits; for example treatment uveitis , reducing emissions from point sources such as coal-fired power plants and from mobile sources such as transportation could provide significant health benefits by reducing exposure to fine particulate matter (Balbus and others 2014) treatment of ringworm . Projecting how health costs could evolve as the climate continues to change also requires consideration of future development pathways (Ebi 2013) medicine 91360 . Five socioeconomic development pathways describe the evolution of demographic treatment xanthelasma , political, social, cultural, institutional, economic, and technological trends through this century, along axes describing worlds with increasing socioeconomic and environmental challenges to adaptation and mitigation. Also considered are ecosystems and ecosystem services affected by human activities, such as air and water quality. Each development pathway has very different implications for the burdens of climate-sensitive health outcomes and health system capacities to prepare for and manage risks associated with climate variability and change. Using these pathways facilitates exploration of the possible impacts and costs associated with mitigating greenhouse gas emissions to a certain level and the extent of efforts required to adapt to that level. This pathway includes the following features: Population health improves significantly, with increased emphasis on enhancing public health and health care functions. Improvements in this development pathway will reduce the burden of climate-sensitive health outcomes even before considering any impacts of climate change. Another development pathway describes a world separated into regional blocks with little coordination between them (Ebi 2013). This world is failing to achieve global development goals, with regional blocks characterized by extreme poverty and pockets of moderate wealth and the bulk of countries struggling to maintain living standards for their rapidly growing populations. All countries experience a double burden of climate-related infectious and chronic health outcomes. Further, governance and institutions are weak, international cooperation is limited, investments in public health and health care infrastructure are low, and the number of public health and health care personnel is too small to address health needs. In this development pathway, the challenges to managing the health risks of climate variability and change increase over time, with rising and increasingly unaffordable costs in more vulnerable countries and regions. The other three pathways explore a world that continues along its current trajectory, with health improving but at a slower rate than in the pathway aiming for sustainable development; a highly unequal world where adaptation is difficult, but technologies are developed and deployed to reduce greenhouse gas emissions; and a world with low challenges to adaptation, but where mitigation of greenhouse gas emissions is difficult for a range of technological and other reasons. Each has different implications for the health costs of climate variability and change. These include the unique nature of the threat of climate change to the incidence, geographic distribution, and seasonality of a wide range of health outcomes (with risks and uncertainty increasing over coming decades) and the temporal displacement between the causes of climate change (human activities leading to the release of greenhouse gases and natural climate variability) and the projected timing of health impacts. Further, the costs of proactive mitigation for managing health risks of climate change will be incurred years to decades before benefits in reducing climate change are evident. Precisely timing investments will not always be possible given inherent uncertainties about the magnitude, rate, and timing of climate change. The hazards created by a changing climate will interact with the sensitivity of populations and regions and with their capacity to prepare for and cope with hazards as they arise. This creates complex relationships between climate change and health outcomes that will vary over temporal and spatial scales. All countries, however, will experience hazards, and all countries will need to adapt and mitigate. The differences across countries mean that the costs of adaptation will vary over time and space. Given the limited capacity of health systems to manage current climate variability and change, the costs of adaptation are likely to be high in the longer-term, as health systems incorporate climate change into policies and programs. Once adaptive risk management processes are established and climate change mainstreamed into policies and programs, costs by mid-century will depend on the health impacts associated with the magnitude and pattern of climate change, which, in turn, will depend on the extent of mitigation over coming decades. Adding to these complexities are the costs associated with adaptation in other sectors. Information on some adaptation options can be estimated from other chapters in this volume, such as the costs of surveillance and treatment for malaria or other vector-borne diseases. However, there are challenges in estimating what portion of the costs of extending current surveillance and health care systems to prepare for changes in the geographic range of malaria could be due to climate change versus other possible drivers of change, such as land use changes. Other issues that arise when considering the costs of adaptation include how to limit double counting. For example, climate change is increasing the number of cases of undernutrition, malaria, and diarrheal disease in many regions (Smith and others 2014). It is not clear how to count the costs of preventing and treating these health outcomes accurately. Many researchers and modelers are estimating the costs of various mitigation options. Although health systems are a source of greenhouse gas emissions, the sector should reduce these emissions as quickly as possible.
