The example shown is from real observations published from studies with lymphocytic choriomeningitis virus (7 prostaglandin injections erectile dysfunction purchase super p-force oral jelly 160 mg with visa,8) erectile dysfunction doctor cape town buy 160mg super p-force oral jelly with visa. An Overview of the Hemorrhagic Fevers 205 the third route of viral emergence is when people increase their contact with vectors or humans that carry virulent viruses erectile dysfunction patient.co.uk doctor safe 160 mg super p-force oral jelly. As the need for more farming or grazing lands increases erectile dysfunction and marijuana buy super p-force oral jelly 160mg overnight delivery, humans penetrate the rain forests or enter new environmental niches and come in contact with rodents and other vectors that carry viruses erectile dysfunction melanoma cheap 160mg super p-force oral jelly visa. An example of behavior that encourages infection among humans is the African custom of staying in direct contact with sick relatives erectile dysfunction drugs lloyds generic super p-force oral jelly 160mg with visa. In Zaire (renamed the Congo Republic in 1997), during the 1995 Ebola outbreak, healthy relatives shared hospital beds with the ill, and in one hospital, seventeen of the twenty-eight who had been healthy contracted Ebola and died. In contrast, none of the seventy-eight persons who visited Ebola patients in the hospital, but did not touch them or share their beds, got Ebola. A fairly recent modification in human behavior that has spread infection is the accessibility of rapid and frequent travel to distant areas. The fourth origin of new viruses is simply an increase in their recognition and classification as biomedical and research technologies advance. For example, hepatitis viruses, which infect the liver, were categorized not long ago as hepatitis A virus, hepatitis B virus, and non-A/non-B hepatitis virus. With newer molecular techniques for identifying viruses by cloning, hepatitis viruses D through G have now been isolated, more than doubling just this one group of pathogens. The fifth source of new viruses is referred to as the mystery source because the cause is completely unknown. For example, the recent Ebola virus outbreak in Kikwit, Zaire, was traced to an index case, a charcoal worker/supplier. Before the outbreak was identified, he died but had infected thirteen of his relatives who also died. The social custom among his people of touching the dead was probably responsible for this instance of spreading infection. Those taken to the hospital infected hospital personnel and others, until the Ebola spread to 316 individuals, of whom 244 died. Investigators are still evaluating insects, rodents, other wild life, and so on, in concentric rings outward, like circles made when a stone drops in water, from the charcoal pit where he worked and the house where he lived. In February 1996, thirteen individuals died in Gabon, West Africa, from Ebola after feasting on a chimpanzee. This outbreak was unusual because, since several of the classic signs associated 206 Viruses, Plagues, and History with Ebola infection were missing from the patients, their disease was hidden even while rapidly being transmitted to doctors, nurses, and other health-care workers who cared for them. The native custom of washing the body of those who have died no doubt caused the disease to spread so robustly. By August of 2007, the first evidence that fruit bats were likely reservoirs of Ebola and Marburg viruses was recorded (7, 8). Thus, in the wild, fruit bats are believed to be a (the) vector of numerous diseases, whereas infections of Ebola travel by direct contact of those who are not infected with lingering viruses in sick or dead infected persons. The person-to-person contact occurs through mucous surfaces, skin abrasions, contaminated needles or blood/blood products. A new virus (morbillivirus), believed to be related to the measles family, caused an outbreak of acute respiratory disease in horses at a stable in Brisbane, Australia, in 1994. Then, two humans became infected, a stable hand who recovered after several weeks and a horse trainer who died one week after becoming ill. The historic struggle between viruses and humans described in the chapters on smallpox and measles and the more recent twentieth and twenty-first century battle with polio continue today and into the future. Like its relatives, Lassa fever virus causes persistent infection in the host, that is, a long-term infection that does not directly kill. It is by contact with such excretions from the rodent that humans become infected. Although no chronic or persistent arenavirus infections have been found in humans, Lassa fever virus has been isolated from the urine of patients as late as one month after the onset of acute disease. Since no insects are known to transmit this disease, its spread to humans occurs only when humans come in close contact with the infected rodents in their natural habitat. Lassa fever was first recognized in West Africa in 1969 but likely has existed in that region for much longer. The natural carrier is the rodent called Mastomys natalensis (multimammate mouse). In Africa, Lassa fever has struck natives, travelers on business, missionaries, and tourists. However, the cases that have provoked international fear are the several explosive hospital outbreaks. Laura Wine, a nurse working in the small mission hospital, Church of the Brethren, in Lassa, Nigeria, was in good health until about January 12, 1969, when she complained of a backache. On January 20th, she reported a severe sore throat, but the physician who examined her found no signs to account for her discomfort. The next day, she complained that she could hardly swallow; she had several small ulcers in her throat and mouth, an oral temperature of 100fiF, and bleeding from body orifices and hospital-induced needle puncture wounds. By January 24th, she was suffering from sleepiness and some slurring of speech; late in the day she appeared increasingly drowsy. Charlotte Shaw, at the Bingham Memorial Hospital in Jos, Nigeria, was on night call when Ms. Shaw had a chill with headache, severe back and leg pains and mild sore throat, a clinical picture similar to that of Ms. Seven days after the onset of symptoms, a rash appeared on her face, neck and arms and spread to her trunk and thighs. The rash appeared to be petechiae (small hemorrhages), and blood was oozing from several areas of her body. By February 12th, her face was swollen; she had shortness of breath, a rapid, weak pulse. Autopsy showed the presence of fiuids in each pleural (chest) cavity and in the abdomen. Lily Pinneo, working at the same Nigerian hospital, Bingham Memorial, had nursed both these patients and had assisted in autopsy of the second patient. After another three days, she had a sore throat and petechiae and was admitted to the hospital. Since this was the third case in progression, the physician decided to send the patient to the United States for diagnosis Lassa Fever 209 and treatment. She was fiown to Lagos, Nigeria, where she lay for four days in an isolation shed, and then to New York attended by a missionary nurse. Pinneo were carried to the Rockefeller Foundation Arbovirus Laboratory at Yale for study. Even so, the patient recovered strength slowly, became fever-free and was discharged from the hospital on the 3rd of May. Jordi Cassals of the Yale University Arbovirus Research Laboratory, who was working with specimens from Ms. Because he had developed symptoms like those of the other three patients, he was admitted to the Columbia University Presbyterian Hospital. Other tests confirmed that all four patients had been infected with Lassa fever virus. By November, work began on the live virus isolated from patients and passaged in mouse brains. On the day after Thanksgiving, he entered a local hospital and died from Lassa fever before blood from an immune donor (such as Dr. The Yale Arbovirus Laboratory decided not to perform any more experiments with live Lassa fever virus. Most are suspected of having malaria, an extremely common disease in that area also accompanied by fever, or of having a bacterial or viral infection. Invariably, their contact with the virus has been as short as five or as long as twenty-one days earlier. After an additional week of progressively worsening sore throat, diarrhea, and cough, pain surges through the chest and abdomen. Frequently red lesions erupt inside the mouth; the patients become anxious and appear deathly ill as their faces swell and their eyes redden. Blood leaks from small blood vessels, called capillaries, and from needle punctures made during hospital care. As internal bleeding worsens, the patients become delirious or confused, and many convulse before dying. Lassa fever virus is constantly present in portions of West Africa, particularly in Guinea, Liberia, Sierra Leone, and Nigeria. An estimated 100,000 to 300,000 residents incur these infections each year with approximately 5,000 to 10,000 deaths. For about 80 percent of those infected with the virus, the disease is mild, although the remaining 20 percent suffer severe involvement of multiple bodily systems that, during epidemics, can reach a 50 percent or more level of fatality. Additionally, 15 to 20 percent of patients hospitalized for Lassa fever die from the illness. The death rate is extraordinarily high for women in the third trimester of pregnancy, and close to 95 percent of fetuses die in utero when the mothers have been infected. Of those who recover, deafness frequently follows, occurring in approximately one-third of the subjects. Estimates are that fewer than 10 percent of African patients with Lassa fever appear at medical care stations; the vast majority stay in their homes or in the bush. Those who do come to medical clinics or hospitals, once they begin to bleed, have the potential to infect nurses, orderlies, and physicians through blood contamination because their blood contains high levels of infectious virus. The death rate among hospital workers varies from outbreak to outbreak; the worst reported is about 60 percent and the least 10 percent. As the infection spreads, attending personnel and families of the patients sicken and die. Despite its virulence, Lassa fever has yielded but few of its secrets to those studying tissues from the victims. Little has been found to help in understanding the pathogenesis, or cause, of the disease (1). Although the liver is the most consistent site of disease, only a modest number of liver cells are destroyed, probably accounting for the absence of jaundice in these patients. Damage to the spleen is common, as is the loss of white blood cells such as T lymphocytes and macrophages in that organ. But many areas of the body become swollen, and, occasionally, T cells and other Lassa Fever 211 lymphocytes infiltrate a variety of tissues. The reservoir for Lassa fever virus is rodents, which can retain a longterm, persistent infection with the virus. Secretions of urine or feces from infected rodents then contaminate humans who come into contact with them. The rodent-to-human transmission is augmented by human-tohuman transmission, which spreads the viruses via contaminated blood, excreta, or saliva. Sadly, the African custom of nursing patients in homes and hospitals where relatives sleep in close quarters with the infected patient helps to spread the disease during both the incubation period and acute infection. Home nursing care nearly always involves direct contact with infected or dead persons through mucosal surfaces, skin abrasions, and contaminated needles/syringes/blood supply. After the virus enters its host, a fourto twelve-day incubation period passes, then the symptoms of disease suddenly begin. Usually, a fiu-like syndrome of fever, chills, and malaise with muscle and headaches is followed by abdominal pain, nausea, and vomiting. The terminal stage adds poor coagulation, increased vascular permeability, hemorrhage, and neurologic symptoms. Those progressing to death have extremely large amounts of virus in their blood but little evidence of a functional (innate or adoptive) immune response. Most of our understanding of the pathogenesis (disease causation) of Lassa fever virus is by analogy with lymphocytic choriomeningitis virus, the prototype Old World arenavirus. Like Lassa fever virus, lymphocytic choriomeningitis virus utilizes a molecule called alpha-dystroglycan as its receptor for attachment on and entry into cells (5). Dendritic cells are the players of the immune system that are essential for initiating the innate and adoptive immune response. Among various cell populations that constitute the immune system, dendritic cells express the greatest amounts of the viral receptor alpha-dystroglycan on their surfaces (6,7). That is, greater than 99 percent of the total amount of alphadystroglycan found in the immune system is on dendritic cells with less than 1 percent on T and B lymphocytes. As carefully worked out and well established during intensive research, we know that those strains of lymphocytic choriomeningitis virus that bind at the highest affinity (most tightly) to alpha-dystroglycan preferentially infect dendritic cells and alter their ability to initiate effective and efficient immune responses (6,8). The consequence of suppressing such innate and adoptive antiviral immune responses is that the viruses are free to replicate unchecked. Identification of the virions is useful for diagnosis because of the variation in size (polymorphism) and electron-dense ribosomes within virions.

Girls acquire more fat mass than do boys and boys frequently lose body fat during the pubertal growth spurt erectile dysfunction herbal treatment options purchase super p-force oral jelly 160mg free shipping. Consequently erectile dysfunction holistic treatment purchase super p-force oral jelly 160 mg online, puberty results in a large increment in Vo2max whether expressed in absolute or relative terms in boys impotence with diabetes buy super p-force oral jelly 160 mg fast delivery. Regular endurance exercise can result in a significant increment in the Vo2max of boys and girls (Brown et al erectile dysfunction treatment for heart patients buy on line super p-force oral jelly. It is generally assumed that the pattern of substrate utilization in children during rest and exercise is similar to that in adults erectile dysfunction age 75 order 160mg super p-force oral jelly visa. However impotence when trying to conceive proven super p-force oral jelly 160 mg, the data on effect of exercises of graded intensities and duration on the balance of substrate utilization in children are scarce. Physical activity levels in children vary widely, as they are capable of large amounts of spontaneous, self-directed physical activity (Blaak et al. The effects of exercise on body composition in children are likely greater than in adults, because of the much greater levels of growth hormone in children (Borer, 1995). Because growth hormone has both anabolic (tissue-building) and lipolytic (fat-mobilizing) effects (Bengtsson et al. Furthermore, not only is there a decline in the frequency of physical education participation by high school students, but there is also a steady decline in the vigor of participation, as estimated by length of time engaging in physical activity/exercise during class. More recent efforts using resistance exercise training, or combinations of resistance and endurance exercises, have been tried to maintain the interest of participants as well as to positively affect body composition through stimulation of anabolic stimuli (Grund et al. Practitioners of speed, power, and resistance exercises can change body composition by means of the muscle-building effects of such exertions. Moreover, exercises that strengthen muscles, bones, and joints stimulate muscle and skeletal development in children, as well as assist in balance and locomotion in the elderly, thereby minimizing the incidence of falls and associated complications of trauma and bed rest (Evans, 1999). While resistance training exercises have not yet been shown to have the same effects on risks of chronic diseases, their effects on muscle strength are an indication to include them in exercise prescriptions, in addition to activities that promote cardiovascular fitness and flexibility. Supplementation of Water and Nutrients As noted earlier, carbohydrate is the preferred energy source for working human muscle (Figure 12-7) and is often utilized in preference to body fat stores during exercise (Bergman and Brooks, 1999). However, over the course of a day, the individual is able to appropriately adjust the relative uses of glucose and fat, so that recommendations for nutrient selection for very active people, such as athletes and manual laborers, are generally the same as those for the population at large. With regard to the impact of activity level on energy balance, modifications in the amounts, type, and frequency of food consumption may need to be considered within the context of overall health and fitness objectives. Such distinct objectives may be as varied as: adjustment in body weight to allow peak performance in various activities, replenishment of muscle and liver glycogen reserves, accretion of muscle mass in growing children and athletes in training, or loss of body fat in overweight individuals. However, dietary considerations for active persons need to be made with the goal of assuring adequate overall nutrition. For the healthy individual, the amount and intensity of exercise recommended is unlikely to lead to glycogen depletion, dehydration, or water intoxication. Nonetheless, timing of post-exercise meals to promote restoration of glycogen reserves and other anabolic processes can benefit resumption of normal daily activities. Additionally, preexisting conditions can be aggravated upon initiation of a physical activity program, and chronic, repetitive activities can result in injuries. For instance, running can result in injuries to muscles and joints of the lower limbs and back, swimming can cause or irritate shoulder injuries, and cycling can cause or worsen problems to the hands, back, or buttocks. Fortunately, the recommendation in this report to accumulate a given amount of activity does not depend on any particular exercise or sports form. Hence, the activity recommendation can be implemented in spite of possible mild, localized injuries by varying the types of exercise. Activity-related injuries are always frustrating and often avoidable, but they do occur and need to be resolved in the interest of longterm general health and short-term physical fitness. Dehydration and Hyperthermia Physical activity results in conversion of the potential chemical energy in carbohydrates and fats to mechanical energy, but in this process most (~ 75 percent) of the energy released appears as heat (Brooks et al. Evaporative heat loss from sweat is the main mechanism by which humans prevent hyperthermia and heat injuries during exercise. Unfortunately, the loss of body water as sweat during exercise may be greater than what can be replaced during the activity, even if people drink ad libitum or are on a planned diet. This can be aggravated by environmental conditions that increase fluid losses, such as heat, humidity, and lack of wind (Barr, 1999). Individuals who have lost more than 2 percent of body weight are to be considered physiologically impaired (Naghii, 2000) and should not exercise, but rehydrate. Even exposure to cool, damp environments can be dangerous to inadequately clothed and physically exhausted individuals. Accidental immersion due to capsizing of boats, poor choice of clothing during skiing, change in weather, or physical exhaustion leading to an inability to generate adequate body heat to maintain core body temperature can all lead to death, even when temperatures are above freezing. Prevention of hypothermia and its treatment are beyond this report; however, hypothermia is unlikely to accrue from attempts to fulfill the physical activity recommendation. Because water and winter sports are gaining popularity and do provide means to enjoyably follow the physical activity recommendation, safe participation in such activities needs special instruction and supervision. However, Manson and colleagues (2002) recently reported that both walking and vigorous activity were associated with marked reductions in the incidence of cardiovascular events. In this triad, disordered eating and chronic energy deficits can disrupt the hypothalamic-pituitary axis, leading to loss of menses, osteopenia, and premature osteoporosis (Loucks et al. While dangerous in themselves, skeletal injuries can predispose victims to a cascade of events including thromboses, infections, and physical deconditioning. Prevention of Adverse Effects the possibility that exercise can result in overuse injuries, dehydration, and heart problems has been noted above. Consequently, a prudent approach to initiating physical activity or exercise by previously sedentary individuals is recommended. The evaluation should include a stress electrocardiogram and blood pressure evaluation. For all individuals initiating an exercise program, emphasis should be placed on the biological principle of stimulus followed by response. Hence, easy exercises must be performed regularly before more vigorous activities are conducted. Similarly, exercise participants need to rest and recover from previous activities prior to resuming or increasing training load. Also, as already noted, conditions of chronic soreness or acute pain and insomnia could be symptoms of over-training. Hence, activity progression should be discontinuous with adequate recovery periods to minimize chances of injury and permit physiological adaptations to occur. Attention also needs to be given to stretching and strengthening activities as part of the physical activity core to healthful living.

Each category may be further subdivided into uses for individual diets and for group diets (Figure 13-1). Included in this chapter are specific applications to the nutrients discussed in this report. There is no method to adjust intakes to account for underreporting by individuals and much work is needed to develop an acceptable method. Furthermore, large day-to-day variations in intake, which are exhibited by almost all individuals, mean that it often takes a prohibitively large number of days of intake measurement to approximate usual intake (Basiotis et al. As a result, caution is indicated when interpreting nutrient assessments based on self-reported dietary data covering only a few days of intake. Finally, because there is considerable variation in intakes both within and between individuals, as well as variation associated with the requirement estimate, other factors must be evaluated in conjunction with the diet. The nutritional status of an individual can be definitively determined only by a combination of dietary, anthropometric, physiological and biochemical data.

The fnal pages are given over to separate maps on criminalisation impotence following prostate surgery 160 mg super p-force oral jelly fast delivery, protection and recognition. In the entries on the criminalising States, and throughout the document, there is a heightened focus on how the United Nations Treaty Bodies have urged States regarding sexual orientation issues in the past two years. These entries also include information on how these States have responded to recommendations made in their 1st and 2nd cycle Universal Periodic Review processes. As such, we are on a constant search to more precisely categorise the state of law pertaining to sexual orientation. It is through the various inputs of readers and practitioners that we are able to pick up on winds of change, and we wholeheartedly welcome participation, correction and critique on the information we present. There are 75 States that we classify as criminalising States: it should be noted that some of these States either have no law, or have such repressive regimes (like Egypt, Qatar and Iraq) that same-sex sexual relations are functionally severely outlawed. We note that in 45 of these States (24 in Africa, 13, in Asia, six in the Americas and two in Oceania) the law is applied to women as well as men. This year we list 103 countries (including Egypt) with an equal age of consent law, and 16 that have an unequal age threshold: a 2015 law in Chile stipulates the sexual act with someone of the same sex below the age of 18 constitutes rape, while for diferent sex sexual activity the age is 14. Further, it appears that Brunei Darussalam has not in fact bought the third phase of the 2014 Syariah Penal Code Order, and there is no sign that the threatened death penalty is to be implemented (for the crime of Liwat that includes same sex relations between consenting same sex partners). However, although is understood that the United Arab Emirates has not implemented it under the Sharia code, it remains a possibility under interpretations current in the Emirates. Researchers at OutRight Action International provided us with information on 13 more States in North Africa and the Middle East where similar laws actively target public promotion or expression of same-sex and trans realities. With the rise in the use of digital devices in these parts of the world, deployment of these laws becomes all the more sinister. We are again seeing a rise in proposals for their adoption: at an advanced stage in Kyrgyzstan, and being strongly mooted in 2016 in Kazakhstan, Ukraine, Belarus, Bulgaria and Latvia. Laws on discrimination in the workplace have substantial impact on those who are protected by them: allowing not only a basic independent income, but importantly the ability to fourish in their work. Angola included it in 2015, and we discovered Indonesia, Thailand and Vanuatu also have such provisions. Likewise some research allowed us to see that there are actually 13 States that contain Constitutional provisions that specify sexual orientation in their discrimination protections. We are aware that this category could be flled out more, and that this category can also slip into one where administrative or local law may apply in the implementation of non-discrimination provisions. Regarding hate crime and incitement to hatred we list 40 and 36 States respectively in 2016 that we identify as enacting such protections, at least in law. There are currently 22 States in the world that recognise and provide for same-sex marriage. The United States, after years of litigation at the state-level, fnally achieved a Supreme Court ruling in June 2015. We include Brazil and Mexico as marriage States in this edition because in both cases, through one legal route or another, it appears to be possible to marry in most provinces of those States. We are hugely grateful to the individuals who have taken on, in a voluntary capacity, the task of translating this text into Spanish (Lucas Ramon Mendos and Victoria Chavez) French (Emmanuel Lauray), Arabic (Ezzedin Fadel), and Chinese (Hou Ping and Gong Yu). It the 11th updated version, evolved from the original report which was researched and compiled by Daniel Ottosson from 2006 until 2010, by Eddie Bruce-Jones and Lucas Paoli Itaborahy in 2011, by Lucas Paoli Itaborahy in 2012, and by Lucas Paoli Itaborahy and Jingshu Zhu in 2013 & 2014, and Aengus Carroll Lucas Paoli Itaborahy in 2015. Within those Concluding Observations, there was also a signifcant increase in the number of references to intersex persons: from seven in 2014 to 31 in 2015. In that context, there was an absolute increase to 53 from 32, yet, the number of Trans-specifc recommendations remained as low at eight (as opposed to six in 2014). This, of course, demonstrates a deeper understanding of diversity beyond sexual orientation, as well as improvements in visibility and attention to diferent populations, but it also comes with complications of confation of issues. As a result, increases in references may not be as high proportionally as they seem numerically. Moreover, in some cases, the problem may be a lack of understanding or sensitivity among particular Committee Members responsible for drafting Concluding Observations. There is a very high number of variables afecting whether a Committee discusses a topic, including the type of information submitted, the timing of a submission, participation at the review session, the relative importance of other human rights issues, and the views of individual Committee Members. A second core issue in considering the variable in this work is the timing of a submission. For example, if the Human Rights Committee has not raised a topic in its List of Issues (the questions that the Committee sends to the State prior to a review), it is highly unlikely that the topic will be raised in later sessions. Other Treaty Bodies are more fexible in this context, but the best practice for human rights defenders is to initially submit information to shape the List of Issues going to the State, and then again in time for the session where its review is being held. Personal testimonies and information coming directly from those working on-the-ground bears great weight with Treaty Bodies. And crucially, through their questioning, Committee Members gain deeper insight into unfamiliar areas that may outside their realm of experience; a cognisance that informs their ongoing work. It is for this reason that ongoing outreach and sensitisation eforts with the Committees are essential. Both Committees, moreover, have a deep understanding of multiple discrimination and intersectional realities. The Committee against Torture has issued very detailed recommendations on intersex persons that were shaped by submissions and briefngs made by intersex human rights defenders. Such recommendations go beyond simply encouraging that States combat violence: they give guidance on the framework required. It is worth noting again, however, the danger of confating issues of gender identity recognition and prohibiting surgeries on intersex persons. Civil society is involved in the process every step of the way: from helping its own government to better understand the situation on the ground, to writing shadow reports, to encouraging other governments to make recommendations that will make a diference, through to the helping its government implement the recommendations made to it. We also explore examples of some countries that have implemented recommendations and of some others, who despite formally accepting such recommendations, have failed to live up to their commitments. Importantly, it has acted as a trigger moment for institutional, policy and legal change. For example, whilst not receiving any recommendations in the frst cycle, States like Georgia, Croatia, Liberia, Armenia and Guinea, did do so in their second reviews. Made by more conservative States, there is a concern that this is being used to undermine family diversity: a concern to sexual and gender minorities. Over 20 of these recommendations have been accepted by States, with some more progressives ones explaining their decision and explicitly stating that they accept the recommendations on the understanding that it includes diverse family forms. However, there is a need for recommendations to be much more specifc as the third cycle opens. This means ensuring States make more specifc gender identity and gender expression recommendations. It also means getting a State to make the frst intersex/sex characteristics specifc recommendation. In 2015, Montenegro urged Jamaica and Kyrgyzstan to implement non-discrimination provisions to combat violence. For example, in 2013, Australia recommended that Montenegro take additional concrete steps to combat discrimination on the basis of race, sexual orientation, disability and gender identity: in 2014 Montenegro passed such a comprehensive non-discrimination Bill into law. However, these issues have not received the same momentum in discussions about development. As discussed in more detail below, the development and human rights frameworks have close ties to each other, both conceptually and operationally. Since then, member States have adopted treaties addressing civil and political rights, economic, social, and cultural rights, racial discrimination, and the rights of children, migrant workers, and people with disabilities. The development agencies that we now know as the World Bank Group were initially created in the 1944 Breton-Woods Conference in which the allied nations established the post-war fnancial system. For several decades, development agencies used national-level economic indicators to gauge standard-of-living. In the late-1980s, Indian economist Amartya Sen developed an approach to development which focused on individual freedoms rather than national economic results. The human development approach defnes a process in which an individual can formulate their own sexual orientation and gender identity and seek support to live a life of their choosing. Since then, a series of world conferences and summits has produced sets of development goals which, all together, have come to be known as the development agenda. In 2015, the Sustainable Development Goals were adopted, replacing the Millennium Development Goals that had been adopted 15 years earlier. Increasingly, concerns about equity for marginalised groups have emerged to shape development priorities, particularly around gender equity, but also for people with disabilities and for ethnic and racial minorities. These eforts constitute some of the frst attempt to measure human development on a global level. Because the two frameworks are diferent, a development agenda requires a separate analysis. Advocacy and public education activities related to human rights predominate over services related to development. The question asserted by the human rights system is whether a State and other important institutions are in compliance with human right standards. Institutions are seen as a means to an end, the ultimate goal being an improvement in individual outcomes and well-being. Some development measures are based on individual-level outcomes, such as health status, expected life-span, income levels, educational attainment, job skill levels, rates of violence, and ability to obtain food and housing. As a starting point, the human rights approach might look at the policies of the employer, the relevant laws, and whether there are any patterns of unfair treatment by the employer. The goal of good policy, according to the human rights framework, is to fully comply with human rights standards, sometimes without regard to trade-ofs and costs of compliance. Though some progressively realisable rights, like the highest attainable standard of health, can be calibrated for budgetary limitations, many rights are absolute. Many in the development feld rely on economic methods and are able to use those methods to balance trade-ofs that may occur as a result of policy choices. According to these methods, a policy is preferred if it makes some people better of and no one is worse of (or, relatedly, those made worse of can be fully compensated). Though this may vindicate the rights of someone fred from a job, in the long run placing the same resources into a jobtraining program may be a better strategy to improve their ability to earn a living. Other goals within the development framework might include moving toward equality in outcomes (as with the Sustainable Development Goals), avoiding environmental harms, or promoting democracy. Given multiple goals, development policy must incorporate potential trade-ofs of each of those goals.
