This thesis investigated a tip-over stability of mobile boom cranes with swinging payloads. Base and crane motion presents a tip-over problem. Attaching complex payloads further complicates the problem. They study began with a single-pendulum payload to analyze a tip-over stability characteristics under different conditions. A simple tip-over prediction model was developed with a goal of limiting a computational cost to a minimum. The stability was characterized by a tip-over stability margin method. The crane's tip-over stability was also represented by the maximum possible payload it can carry throughout the workspace. In a static stability analysis, mobile boom crane was assumed to be stationary, thus with no payload swing. The study provided basic understanding on the relationship between tip-over stability and boom configuration. In a pseudo-dynamic stability analysis, the method incorporated payload swing into the analysis by adding estimated maximum payload swing due to motions. To estimate the angles, differential equations of motions of payload swings were derived. The thesis extended the study to a double-pendulum payload. The maximum swing angles estimated in the single-pendulum case were directly applied to the double-pendulum case. To validate the analytical methods, a full dynamic multi-body simulation model of a mobile boom crane was developed. The predictions from the previous analysis were verified by the simulation results. The prediction model and the analytical methods in the thesis provide a significant tool for practical application of tip-over stability analysis on mobile boom cranes. The experimental results increase the confidence of the study's accuracy.

Our current LTC system is burdensome to state and federal governments, to family members, and to individuals’ pocket books; it is not expected to endure the weight of the baby boom generation. Total national spending for long-term care in 2005 was $207 billion and is only expected to rise. This study examined the LTC planning behavior of individuals of baby boom birth years (1946 to 1964), focusing on the influence of individuals’ views about whose responsibility is the provision of LTC on planning behavior. Specifically, the study has three aims: to 1) to describe the LTC planning behavior among baby boom aged adults; 2) examine baby-boom aged adults’ views on whose responsibility is the planning/provision/cost of LTC (location of responsibility); and 3) examine the influence of potential predictors of individuals’ LTC planning with specific focus on the influence of location of responsibility (LOR). Data was collected between May and August of 2009 using a mixed modes self-administered 80-item original survey via the internet and regular mail (study sample = 1,066; 1,166 responding; response rate 58%). The study population consists of benefit-eligible Black, Hispanic/Latino, and Non-Hispanic White faculty/staff born in or between the years of 1946 and 1964 from a large southwestern university. This study found overall low levels of LTC planning; however, with regard to LTCI purchase, the participation rate is good relative to the national coverage rate. The study informs us that baby-boom aged individuals as a whole believe themselves (individuals) to have a high level of responsibility for their own potential LTC needs, but also that responsibility lies with the government, employers, and adult children as well. Consistent with hypotheses, LTC awareness/avoidance predicted a higher level of extent of planning (gathering, deciding, and concretizing); worthwhileness and self-efficacy predicted LTCI purchase; and awareness, subjective norm, worthwhileness, and self-efficacy predicted LTC specific savings. Additionally, individual responsibility (negatively), female (positively), income (positively), experience (self and other; positively), LTC knowledge (positively), and Hispanic (negatively) all predicted extent of planning. Employer responsibility (positively), faculty (negatively), marital status (married; negatively), Black (positively), and medical diagnoses all predicted LTCI purchase. And, employer responsibility (positively), government responsibility (negatively), income (positively), experience-other (positively), and knowledge (positively) all predicted LTC-specific savings. Implications for practitioners, employers, program planners, and policy-makers are presented. / text

My dissertation proposes a comprehensive study of the politics of representing the Amazonian territory in literature and culture. Using the context of the Amazonian rubber boom (1879-1912) and its aftermaths in Peru and Brazil, my research evaluates how the Amazon Basin became the focus of political and sentimental debates, triggering discussions to rethink national identity, ethnicity, sovereignty, and modernity at the turn of the twentieth century. Traditionally portrayed as an exotic, primeval land, geographically isolated, and with endless natural resources waiting exploitation by a higher civilizing order, its presence continually frustrated colonizers and investigators who failed to reduce it to a set of manageable meanings. Despite the many books written about the region since its encounter in the sixteenth century to nowadays, the Amazon resists demands to be modern and construed by an imported Western rational. Like the Pampa in Argentina and the Backlands in Brazil, Brazil and Peru's Amazon is a tropical body that calls institutional authority into question. / Romance Languages and Literatures

Over the past several decades, the senior age group has become the fastest growing segment of the population in the United States (Warner, 2011). This study seeks to contribute to the ongoing discussion of the impacts that the increases in senior travel will have on the future transportation systems and planning efforts. The main objective of this research is to conduct an explorative analysis of the changes in senior travel behavior over the past two decades and discuss the implications of these changes to transportation planning in the future. This thesis seeks to further understanding of this topic by providing a detailed analysis and consideration of relevant contexts through a review of previous studies and the author's background in the field of transportation. Results indicate significant changes in travel behaviors and make-up of the senior population. Over the three (1990, 2001, and 2009) survey periods, senior travel changed as a result of increased activity and a need to maintain their typical way of life well into older age. As the baby boom generation continues to out travel each previous generation, there is no evidence to assume that as they reach retirement age that trend will end. Seniors today are remaining active and working well into their older age and the age group has continued to increasingly contribute to total travel. These increases will be echoed by the baby boom generation and must be considered by traffic forecasters, researcher and policy makers in the future.

With the first of the 77 million (www.census.gov) Baby Boomers turning 60 this year, the impact on retirement and retirement communities has suddenly become a vital and pressing issue. The massive numbers of Baby Boomer cohorts have amplified and intensified the importance of whatever experiences they've had at each new moment in their lives. When they reach any stage of life, the issues that concern them — whether financial, interpersonal, or even hormonal — become the dominant social political, and marketplace themes at the time. (www.agewave.com 2006) Retirement will be no different. Using this understanding of the Baby Boomer generation, this study examined their impact on retirement community design.Data specific to Baby Boomer retirement preferences was analyzed, an expert in the field of gerontology at Ball State University was interviewed, research was completed in retirement community design and age related health concerns, and case studies in a range of established retirement communities in southwest Florida were visited, all in an effort to determine what the current trends are in the retirement community market today and how Boomers would effect them.Research showed that Boomers want to pursue new and exciting experiences in their retirement years. They are not willing to settle for a retirement tucked out of the way, out of sight out of mind. They want to be in the middle of activity and enjoyment. They are looking to make a difference and have an impact in this next phase of life.The result of these endeavors is a conceptual design for an active adult retirement community, in northeast Lee County Florida, that will attract Baby Boomers by appealing to their sense of fun, their sense of purpose and their social and environmental conscience. / Department of Landscape Architecture

This thesis examines how Baby Boomers utilize Facebook to promote radical political ideology. A convenience sample of 51 Baby Boomer Facebook profiles were selected and critically analyzed for radical content using Bernard L.Brock’s (1965) A Definition of Four Political Positions and a Description of their Rhetorical Characteristics, and Making Sense of Political Ideology: The Language of Democracy (Brock, et al., 2005). The rhetoric from these profiles was then categorized using James W. Chesebro’s (1972) Rhetorical Strategies of the Radical Revolutionary. Conclusions from the research indicate that radical Boomers on Facebook seem to have moved from real world activism to symbolic action on Facebook through the liking and sharing of radical articles and posts. Though consistent in posting radical content in their profiles, radical Boomers using Facebook in this study utilized profiles more to promote radical culture online than to foment political revolution offline. / Department of Telecommunications

The report is about reducing the Eigen weight of a reach stacker in order to obtain decreased fuel consumption. The detail the product development treats is the telescopic boom. By using steel of higher strength the dimension can be decreased, which in turn results in a reduced weight. Suitable steel for the application might be the high strength structural steel of designation S690QL. With support of calculations and CAD simulations the possible weight reduction is assumed to amount to 28%.

Older adults have the lowest mental health utilization of any age cohort. This study compared baby boomers, born between 1946 and 1964 versus older adults born in 1944 or earlier, on attitudes and intentions to utilize mental health services. Ajzen’s theory of planned behavior and its related constructs of attitudes, subjective norm, perceived behavioral control, and intentions were used as a theoretical model. The Inventory of Attitudes toward Seeking Mental Health Services (IASMHS) and Beliefs About Psychological Services (BAPS) were used for measuring the constructs in the theory of planned behavior. Gender and previous mental health service utilization were also measured. Participants (n = 401) included current and retired faculty and staff from a mid-sized Midwestern University. Statistical analysis, using MANOVA, found main effects for previous mental health experience and age cohort, but not for gender. Those with previous mental health service experience expressed more positive attitudes, intentions, and perceived behavioral control over receiving mental health services. Contrary to the primary hypothesis, the older adult cohort expressed more positive attitudes, greater intentions, was less affected by the subjective norm, and had more perceived behavioral control than baby boomers. Regression analyses, using gender, previous mental health service use, attitudes, subjective norm, and perceived behavioral control accounted for 55.7% of the variance in intentions for the older adult cohort and 58.2% for baby boomers. For both cohorts, attitudes accounted for the greatest amount of variance. Promoting positive attitudes through reducing environmental and economic barriers and increasing education regarding mental health services is likely to increase mental health service utilization in baby boomers and older adults. / Department of Counseling Psychology and Guidance Services

The aim of this study is to design a computer interface, which links the user to commercial Finite Element Analysis (FEA) program, MSC.Marc-Mentat to make automatic FE analysis of an excavator boom by using DELPHI as platform. Parametrization of boom geometry is done to add some flexibility to interface called OPTIBOOM. Parametric FE analysis of a boom shortens the design stages and helps to find the optimum design in terms of stresses and mass.
