To help employers and others identify potential accommodations, the President’s Committee on Employment of People with Disabilities spon- sors the Job Accommodations Network (JAN). The MS page lists dozens of potential accommodations, such as those requested by Sally Ann Jones, whose pre-ADA employer was very accommodating: I worked in an old building. I made them designate a parking spot for me so I wouldn’t have to walk so far, which they did cheerfully. The ﬁrst year I worked there, my office was on the second ﬂoor, and the women’s toilet was on the ﬁrst ﬂoor. I said, “Guys, we have to reverse these toilets,” which they did in a second and didn’t complain about it. Then the building had half a dozen stairs at the front, but there was no handrail. Then, my doctor insisted I had to have an air-conditioned office, so they bought a little air con- ditioner. I was the only person who had air conditioning, so every- body was in my office all the time. And the last thing was, I couldn’t do the damn stairs to the second ﬂoor anymore. So I moved my of- ﬁce to the ﬁrst ﬂoor, then they reversed the bathroom again. When I visited, it didn’t work—a common occurrence, according to Lester. Disputes continue about the costliness of reasonable accommodations and whether these expenses affect an employer’s willingness to hire workers needing ac- commodation (Young 2000). Improving physical access for wheelchair users is gener- ally the most expensive accommodation (Chirikos 1991), but it is not al- ways costly. Wooden ramps to surmount one or two stairs can cost only a few hundred dollars. Despite the ADA’s lofty aspirations, its moral authority, and the boom- ing economy of the late 1990s, unemployment among persons with dis- abilities remained high ten years after the law’s passage (Batavia 2000; Blanck 2000; Stein 2000). Numerous studies from the past ﬁfty years have found comparable overall productivity among workers re- gardless of disability, and disabled workers are more likely than others to stay with their jobs. The law professor Andrew Batavia knew that Title I of the ADA does not require affirmative action in hiring disabled workers. An employer who is intent upon rejecting an applicant with a dis- ability is likely to ﬁnd ways in which to do so without being sub- jected to the substantial risk of a lawsuit. It is difficult to conceive of a law that would be politically feasible and would induce an other- wise recalcitrant employer to hire such an applicant. A few years ago, a colleague at a large university asked me to consider a se- nior academic position. I agreed and was invited to visit by the surgeon leading the recruitment. A few days before the visit, I called the surgeon’s secretary to remind her that my meeting locations must be wheelchair ac- cessible. Embarrassed silence ensued: the secretary and surgeon hadn’t known; my colleague hadn’t told them. The visit was scheduled, and I came—the university’s brochure asserted prominently that they are an equal opportunity employer. But from the outset, the surgeon barely looked me in the eye, he did not seriously discuss details of the job, and he hurried from our last encounter without saying good-bye. I know that I was qualiﬁed for that job, and I know that my wheelchair rattled the surgeon. In the early 1990s, he was managing a large law ﬁrm when he was diagnosed with MS. I went to the people at my law ﬁrm and said, “Look, I’m telling you right up front that I have MS. This is a major league illness, and be- fore we go any further, I am authorizing you to talk to my physician to ﬁnd out the full extent of this illness and how it may affect my job. They came back to me and said, “Gerald, we’re going to do whatever you need. Any problems, anything we can do to make it easier for you, just let us know.
The SSA and workers’ compensation programs use different processes for evaluating dis- ability: the SSA’s “blue book order apcalis sx 20mg otc,” Disability Evaluation Under Social Security (1998) for SSDI and SSI; and the American Medical Association’s Guides to the Evaluation of Permanent Impairment (1993; Cocchiarella and Andersson 2001) discount apcalis sx 20mg with mastercard, used for workers’ compensation disability determinations in most states buy 20mg apcalis sx mastercard.

These questions were asked only of people who reported having had a routine physical examination within the previous three years. The percentage reporting having been asked by their physicians about trouble with ADLs is 10 percent of those without mobility problems and 13, 19, and 27 percent with minor, moderate, and major difficulties, respectively. Questioning about IADL problems is similar: 10, 15, 24, and 26 percent for those with no, minor, moder- ate, and major mobility difficulties, respectively (these ﬁgures come from the 1994 NHIS-D Phase I and 1994 Healthy People 2000 supplement and are ad- justed for age group and sex). We performed multivariable logistic regressions separately for men and women, controlling for age group, race, Hispanic ethnicity, education, and household income. The adjusted odds ratio (95 percent conﬁdence interval) for being asked about contraception for persons with major mobility problems expected to last at least 12 months are 0. Al- though not statistically signiﬁcant, the slightly higher odds ratio for men was provocative and could relate to physicians’ concerns about male patients’ phys- ical abilities to be sexually active (e. These ﬁgures represent adjusted odds ratios and come from the 1994 NHIS-D and Healthy People 2000 supplement, which queried people who had had a routine health-care visit in the last three years (Iezzoni et al. Women over age 49 were asked if they had had mammograms in the prior two years. Women age 18–75 who had not had a hysterectomy were asked if they had had a Pap smear in the last three years. Adjusted odds ratios control for age group, sex (smoking analyses only), race, Hispanic ethnicity, education, income, health insurance, and having a usual source of care. Adjusted odds ratios (95 percent conﬁdence intervals) for persons with major mobility problems were 0. These rates come from the 1994–95 NHIS-D and are adjusted for age group and sex. Specialized geriatric assessment programs began in England in the 1930s, their success leading to establishment of geriatric assessment units as entry points for elderly into the British National Health Service (Urdangarin 2000, 384). In the United States since the early 1980s, geriatric researchers have explored better ways to care for frail elderly people who have multiple health problems, typically including impaired mobility. At issue is whether comprehensive evaluations (of diagnoses, medications, rehabilitation potential, living arrangements) improve outcomes, such as by lowering death rates and enhancing functional abilities and quality of life. Early efforts showed positive results, although later studies proved mixed. Many studies, however, were small and poorly designed, contrasting geriatric evaluation programs with ill deﬁned usual care. Comprehensive geriatric assessment,“the multidisciplinary evaluation and care planning of older adults by more than one health profes- sional, has become a cornerstone of geriatric care systems” (Urdangarin 2000, 383), although it remains unclear how widely these services are used in routine practice. Harvard Medical School, the academic origin of about half of the physi- cian interviewees, did not have a PM&R program until the mid 1990s. A physi- cian familiar with Harvard’s deliberations feels that questions about the scien- tiﬁc basis of PM&R caused the delays. Another physician said that “turf battles” with other clinical specialties within major Harvard teaching hospitals also contributed. The American Occupational Therapy and American Physical Therapy Associations were established in 1917 and 1921, respectively, while the Amer- ican Congress of Rehabilitation Medicine was founded only in 1933 and the PM&R Academy in 1938 (Brandt and Pope 1997, 31). Roosevelt personally lobbied AOA members and recruited the New York orthopedist LeRoy Hubbard to oversee the progress of Warm Springs pa- tients. Hubbard’s positive report convinced the AOA to endorse the Warm Springs hydrotherapeutic center in 1927. Some people get physical or occupational therapy speciﬁcally for voca- tional rehabilitation. Of people with major mobility limitations, just over 20 percent report having received physical therapy speciﬁcally for vocational re- habilitation, as do 13 percent of those with moderate and 11 percent of persons with mild impairments. Among those who received physical therapy for voca- tional rehabilitation, the percentage obtaining these services from state reha- bilitation agencies is 16 for minor, 24 for moderate, and 23 percent for major mobility difficulties. Of people reporting major mobility problems, just over 7 percent received occupational therapy for vocational purposes, as did 3 percent of those with mild and moderate impairments. Among those who received oc- cupational therapy for vocational rehabilitation, the percentage obtaining these services from state rehabilitation agencies is 27 for minor, 32 for moder- Notes to Pages 165–183 / 311 ate, and 26 percent for major mobility difficulties (these ﬁgures come from the 1994–95 NHIS-D Phase II and are adjusted for age group and sex).

Active internal cellular membranes that partially partition the inter- transport allows a cell to maintain conditions different from cellular matrix, and that ultimately become continuous with the surrounding environment. There are two main types of active transport; movement There are three principal mechanisms of outer cellular directly across the cell membrane with assistance from trans- membrane transport (i.
