Cerebrovascular burden (CVB) is a significant factor among the aging population. Age-related cognitive decline is an important social and economic issue, and understanding the mechanisms has clinical implications, both in selecting potential therapies and in choosing specific modifiers for their evaluation.

Show moreCerebrovascular burden (CVB) is a significant factor among the aging population. Age-related cognitive decline is an important social and economic issue, and understanding the mechanisms has clinical implications, both in selecting potential therapies and in choosing specific modifiers for their evaluation. In summary, past work suggests that high CVB is one source of variance in neurovascular functioning among older adults. High CVB and associated brain-changes have been identified as causes of age-related changes and it may be that high CVB is a correlate of age-related changes in sleep quality. The primary hypothesis to be tested is that cerebrovascular burden measured using an index variable reflecting blood pressure, resting heart rate, and blood oxygen saturation, will predict subjective sleep quality in a sample of adults over age 70. Sleep quality was measured using the Pittsburgh Sleep Quality Index. A sample of 8 dementia-free, community dwelling participants over the age of 70 completed the study. Though individual cerebrovascular risk factors (blood pressure, resting heart rate) had moderate but non-significant correlations with sleep quality, only the CVB index variable significantly related (1-tailed) to sleep quality. Findings support the hypothesized relationship. Future research should seek to replicate these findings with a larger sample, and to identify mechanisms by which this relationship may function.

Show moreThe present study sought to determine the direction and degree to which occupations representative of all major occupational categories are viewed as age-typed (i.e., more appropriate for older or younger workers). The 60 occupations examined were the 12 most common and familiar occupations in each of five occupational categories used by the U.S. Census Bureau. I randomly assigned 365 participants to one of three survey conditions. Participants rated the feature centrality, proportional representation, normative age, and optimal performance age of 20 of the 60 occupations and the age-type of 20 different occupations. Results showed that participants reliably rated the occupations on a continuum from highly young-typed to highly old-typed. Occupations viewed as most appropriate for older workers included psychologists (clinical), bus drivers, and librarians, whereas those viewed as most appropriate for younger workers included recreation and fitness workers, bartenders, and hosts/hostesses. Interestingly, despite commonly held stereotypes that older workers are less competent than younger workers (Kite, Stockdale, Whitley, (&) Johnson, 2005), old-typed occupations were viewed as requiring higher competence than those viewed as young-typed. Additionally, roughly three times as many workers are needed to fill the most young-typed jobs compared to the most old-typed jobs (U.S. Census Bureau, 2000). Both of these findings suggest problems for an increasingly aging workforce (Administration of Aging, 2010). I also found that perceived proportional representation accounted for 79% of the variance in predicting the age-type of occupations. This suggests that people rely on general impressions of current worker ages, which supports career timetables theory's approach to the formation of occupational age-type. Implications for theory and research are discussed.

Show moreFor as long as people have held opinions in the political realm, there has been research trying to decipher exactly what people think and believe as well as when they begin to hold these beliefs. This present study sorts the respondents studied into age cohorts and then follows them throughout the data. All of the data used in this study are from the National Election Study Data from 1984, 1988, 1992, 1996, 2000, and 2004. This study is a repeated cross-sectional study since different individuals are used throughout the study, and this study measures opinions only on the aggregate level. Sorting the respondents into age cohorts allows this study to track people of similar age as they respond to different life experiences as well as world events as they age. When appropriate, the data are compared to the main models of political socialization to determine how accurate these generally accepted models are. The items analyzed in this study vary greatly in subject as well as how specific they are. Everything from United States Presidential vote choices, opinions on affirmative action and federal welfare spending to political knowledge is analyzed to ascertain if these things interact with age, and if they do interact with age, to what extent. Besides observing opinions on these issues, certain issues will have their saliency measured throughout the years using the Somers' D statistic. This will help determine what issues people are thinking of when they are forming their ideology. The results from this paper show that some issues and beliefs, such as self-described ideology and political knowledge, are very strongly related to age. Other issues and beliefs in the political realm, such as strength of United States Presidential vote choice and opinions on federal welfare spending, seem to not be related to age or influenced heavily by period effects and other things besides age.

Show moreGiven the growing population of aging adults, there is a need for research examining factors that enhance quality of life for older adults (QoL; Colby (&) Ortman, 2014). Changes in health, relationships, support systems, and social identity are inevitable throughout the lifespan. Therefore, research focused on lessening the negative effects of changes due to aging while also improving QoL is warranted. As such, the aim of the current research study was to examine the extent to which subjective age (SA; how old or young an individual feels), playfulness (PF; (")the ability to frame or reframe everyday situations to experience them as entertaining, intellectually stimulating, and/or personally interesting(") [Proyer, 2015, p. 93-94]), and depression (an emotional state ranging from mild discouragement to feelings of extreme despair [CDC, 2017; Corsini, 2002]) predict QoL ((")a person's sense of well-being that stems from satisfaction or dissatisfaction with the areas of life that are important to him or her(") [Ferrans, 1985, p. 15]) among adults over the age of 55. Using convenience sampling with eligibility requirements, adults (N = 1,315) 55 and older and who spoke and read English were surveyed both face-to-face (F2F) and online (e.g., Amazon Mechanical Turk and a senior educational program). Standard multiple regression was utilized, and results identified a statistically significant model with the variable of depression predicting the largest unique contribution to the model, while PF predicted a small, statistically significant contribution. Subjective age did not statistically contribute to the prediction. Implications from the findings that relate to counselors, counselor educators, and researchers are provided. In addition, the findings provide guidance and a new perspective on variables associated with QoL and aging adults.

Show moreFragile X-associated tremor/ataxia syndrome (FXTAS) is an X-linked late-onset neurodegenerative disorder caused by a noncoding trinucleotide repeat expansion in the FMR1 gene. This gene produces fragile x mental retardation protein (FMRP), an RNA binding protein whose targets are involved in brain development and synaptic plasticity. One of the proposed mechanisms of FXTAS pathogenesis is an RNA gain-of-function in which the repeat expansion causes toxic mRNA that sequesters important proteins in the cell, interfering with their functions. Another suggested method of pathogenesis is through a mutant protein called FMRpolyG. This protein results from repeat-associated non-AUG (RAN) translation, in which the expanded repeats are translated where they otherwise would not be. This protein co-localizes with intranuclear inclusions and nuclear membrane proteins, causing disorganization of the nuclear lamina in FXTAS patient brain samples and neurons differentiated from FXTAS patient-derived induced pluripotent stem cells (iPSCs). iPSC technology involves reprogramming an adult somatic cell back to an embryonic-like state, allowing it to be differentiated into all cell types. A limit with iPSCs, though, is modeling late-onset disorders because the cells lose all age-related features during reprogramming. Progerin, a truncated form of the lamin A protein, has been used to age neurons differentiated from Parkinson Disease (PD) patient-derived iPSCs. Progerin-mediated aging was found to unmask PD-like phenotypes in those neurons, making it a promising technology for modeling late-onset disorders such as FXTAS. In this study, we investigated the link between the aging process and FXTAS pathogenesis in neurons differentiated from FXTAS patient-derived iPSCs with the use of progerin. Progerin transduction was successful in aging the FXTAS neurons. The presence of FMRpolyG was confirmed and an interaction with Lap2b was observed. In some neurons, there was also an observed interaction between FMRpolyG and progerin. Overall, this data suggests that there is an interaction between the mutant FMRpolyG protein and the nuclear membrane during aging, which may contribute to the cell death that causes neurodegeneration in FXTAS patients.

Show moreWoman of Dust: An Exodus is a collection of themed non-fiction experiences and stories with themes, characters, and ideas that coincide deliberately and verge on the cohesiveness of memoir. The overarching themes of this collection are womanhood and coming of age. The stories examine the ways in which childhood crushes, current relationships, parenting, religion, and pets influence the growth of a child into an adult, in this case, a girl into a woman. They take individual moments, conversations, conventions, and thoughts and explore how they shaped the woman who now writes them. Stories range in content from how the standards of a southern Baptist church raised a girl who was afraid to date, drink, or kiss, about the role of God in the narrator's private life, to stories that explore how cartoon Disney prince crushes turn into crushing on neighbor boys and classmates, discovering the narrator's current conceptions of love as different from her early conceptions and questioning the ways in which those conceptions came into existence in the first place. These stories look at the domestic implications of religious life that dictate specific roles for women in a marriage relationship, and how the narrator interprets these implications in terms of her own love and pending marriage. Still other essays investigate how a mother's overbearing fear of sex, men, and drugs drove one daughter to be a small town porn star and drove the other to complete abstinence, how gender conventions shape a girl's mind, and how family life sometimes contradicts the same conventions. While the subject of each story is deeply feminine, revolving around a woman narrator and woman experiences, the content of these stories creates a very human experience, one outside the confines of gender. They are about one girl turned woman, from one perspective, and about one life, but they are mostly about being human, about growing, and about the ways in which humans grow.

Show moreAggressive CMOS technology scaling trends exacerbate the aging-related degradation of propagation delay and energy efficiency in nanoscale designs. Recently, power-gating has been utilized as an effective low-power design technique which has also been shown to alleviate some aging impacts. However, the use of MOSFETs to realize power-gated designs will also encounter aging-induced degradations in the sleep transistors themselves which necessitates the exploration of design strategies to utilize power-gating effectively to mitigate aging. In particular, Bias Temperature Instability (BTI) which occurs during activation of power-gated voltage islands is investigated with respect to the placement of the sleep transistor in the header or footer as well as the impact of ungated input transitions on interfacial trapping. Results indicate the effectiveness of power-gating on NBTI/PBTI phenomena and propose a preferred sleep transistor configuration for maximizing higher recovery. Furthermore, the aging effect can manifest itself as timing error on critical speed-paths of the circuit, if a large design guardband is not reserved. To mitigate circuit from BTI-induced aging, the Reactive Rejuvenation (RR) architectural approach is proposed which entails detection and recovery phases. The BTI impact on the critical and near critical paths performance is continuously examined through a lightweight logic circuit which asserts an error signal in the case of any timing violation in those paths. By observing the timing violation occurrence in the system, the timing-sensitive portion of the circuit is recovered from BTI through switching computations to redundant aging-critical voltage domain. The proposed technique achieves aging mitigation and reduced energy consumption as compared to a baseline circuit. Thus, signi?cant voltage guardbands to meet the desired timing speci?cation are avoided result in energy savings during circuit operation.

Show moreHealthcare services for the aging population in the United States are a complex configuration of acute healthcare organizations, and post acute nursing facilities, home healthcare, and community based services. The system encompasses all services that imply the need for clinical, medical, or professional judgment (Baldrige National Quality Program, 2006). Most Americans believe the system exists to provide preventive services, management for chronic conditions, and health care services to meet the needs of the people (National Committee for Quality Assurance (NCQA), 2004). However, the healthcare delivery system is fragmented across a broad array of settings (Coleman, Smith, Frank, Min, Parry, & Kramer, 2004), plagued by gaps in quality of care, and does not provide optimal care to the majority of American citizens (NCQA, 2004). As a result, national efforts are focused on the identification of quality indicators, performance measures, and the driving need for consensus standards across a multiplicity of providers, payers, and stakeholders. The overarching focus of this effort is to bridge the gaps in health care quality, and reduce documented disparities for vulnerable populations (National Quality Forum (2004). Healthcare transitions occur as patients receive a broad range of services across a multiplicity of providers, payers, and settings. Aging patients > 65 are most vulnerable during these transitions. A poorly executed transition can result in complications for the patient, duplication of tests and services, discharge delays, increased lengths of stay, early readmissions to the acute care setting, frustration for families and care givers, and dissatisfaction with overall services. Management of care and accountability across settings is limited and patients are falling through the cracks in the foundation of the healthcare system (Covinsky, 2003). The intent of this research was to examine healthcare transitions for patients > 65 admitted to a large acute healthcare system, and to identify measurable quality indicators for an innovative delivery model designed to optimize early discharge from the hospital through rapid rehabilitation. This was a quasi-experimental, cross-sectional design measured at the patient level. The research included a total sample of 250 patients representing both the intervention and the control group. The intervention group consisted of 100 patients who were rapidly discharged to a transitional care facility in the community, and 150 patients randomly selected to a control group that did not transition to rapid rehabilitation. The groups were matched as closely as possible by age, gender, race, primary diagnoses, and the complexity of case. Inefficiency was measured by 3 indicators (1) length of stay, (2) total expenses before contractual allowances, and (3) discharge delays from the hospital. Ineffectiveness was measured by 3 indicators: (1) readmission within 30 days, (2) patient safety with falls serving as the proxy, and (3) overall patient satisfaction. Descriptive analysis was performed utilizing SPSS 15.0. Path analysis was method of choice for data analysis and AMOS 7.0 was utilized for the measurement model. Descriptive analysis found a broad range of diagnosis related groups across 183 women and 67 men with a mean age of 80 for both groups. Initial analysis found the intervention group had a mean length of stay of 9.17 days, and experienced 20 readmissions. The control group had a mean length of stay of 6.77 days, and 30 readmissions. The statistical analysis suggested length of stay and cost of healthcare services are statistically significant indicators at the 0.05 or lower level and that patient safety has the potential to be developed as an indicator for effective outcomes. The identification of quality indicators, measurement of efficiency and effectiveness, and establishing predictors for successful healthcare transitions is dependent on the quality and integrity of data abstracted from hospital information systems, accuracy of information in patient records, and the consensus of standards and definitions across a multiplicity of stakeholders. Further research and collaboration is necessary to ensure that patient transition to innovative care programs such as rapid rehabilitation is based on well-defined patient selection criteria. The intent of the methodologies and quality indicators explored in this research supports the increasing need to ensure that inferences and quality measurements drawn from healthcare information is based on valid, reliable, and well defined data sources (Pan, Fergusson, Schweitzer, & Hebert, 2005). This research suggests hospitals are making steady progress to overcome challenges to safe, quality health services as outlined by the Institute of Medicine (2001) for system redesign, but finds specific implications for hospital leadership. There is a need to thread evidence based practice initiatives into hospital and clinical structures to accommodate new delivery models, processes, and case management. Health services information needs to be housed in a central repository or data warehouse to increase transparency of reportable information across systems and to ensure that valid and reliable information is utilized to draw inferences about performance of hospital systems (Selden & Sowa, 2004) and that quality measurements are established to ensure a scientific foundation for the management of healthcare services (Wan, 2002).

Show moreThe solid portion of waste disposal, known as Municipal Solid Waste (MSW) can be landfilled. Landfilling has proved to be a safe, sanitary and economical method of disposal. A by-product from wastewater treatment plants called biosolids is sometimes co-disposed along with MSW in landfills. Recent work at the University of Central Florida has focused on the behavior of the mixture of MSW and biosolids. As an increased amount of waste accumulates in these landfills, it creates a new problem the geotechnical stability of landfills. In current literature, classical geotechnical testing methods have been followed to find the strength properties of these landfill materials. Furthermore, geotechnical methods of slope stability analyses have been employed to determine the stability of landfill slopes. As these materials have a high organic content, their strength properties may potentially change with time because of the decay of the organic materials. In the present work, an attempt is made to monitor the change in the geotechnical strength properties of the landfill materials as a function of time. Direct shear tests used for soil testing, with some modifications, were performed on cured compost samples of MSW mixed with biosolids. Geotechnical strength properties of these cured samples were compared to those of an artificially prepared mixture of MSW and biosolids, from the published literature. In addition, direct shear tests are also performed to find the interface properties of a geonet with the cured samples to check the role of a geonet in reinforcing the landfill slopes. A slope stability analysis software SLOPE/W is used to analyze the stability of the landfills. Cohesion is observed to decrease with time while the friction angle increases with time. Stability (the factor of safety against failure) of landfill slopes increases with time due to increased effective stresses and increased friction angle, as the organic material decays. This may result in additional subsidence but an increase in the effective shear strength with time. Based on the interface test results and subsequent slope stability analyses, it is found that the inclusion of a geonet improves the slope stability of a landfill. This could be a potential benefit to the landfill as reinforcement if properly placed. Based on the slope stability analysis on landfills with different slopes, it is concluded that the slope stability of a landfill is improved by keeping the slopes less steep.

Methods: Compared published measurements of age at menarche, adult height, and within-sample relationships observed in ten studies, for women from several societies and socioeconomic backgrounds, living in the 20th century, Results: In these studies, early maturers were taller during pre-puberty, but had shorter adult height then later maturers. Late maturers experience a longer period of pre-pubertal growth and a delayed age of peak height velocity, leading to an extended overall time of growth, until adult stature was obtained. Conclusions: Improved living conditions and energy balance increase childhood growth rate, and are associated with an earlier puberty, and shorter duration of growth. In developed countries duration of growth may play an increasingly important role in adult stature.

Show moreIn this collection of short stories, the characters struggle to recover equilibrium in their lives that have been turned upside down. They struggle against one another, against change, and against the loss of loved ones. No matter what bonds hold the characters together, the underlying tension of change and reaction permeates their relationships and threatens what they know to be true. A theme of discontent runs in these stories. Something beneath the surface is not right, and the characters struggle to climb out of the mess their lives have become. Some of them have been stifled, like the narrator in "Resounding Gong, Clanging Cymbal," who's being pressured on all sides to marry. Some of them are toeing the line of fitting in and being independent, like the teenagers in "Hibiscus Boulevard," who, caught up in the last days of summer, are more concerned with being adults than being kids. In the title story, the teenagers in a small town find a way to memorialize one of their own by performing the act that caused him to die. The cautious bonds between the characters are continuously being worked by one another, by oppressive scenery and location, by the aftereffects of dysfunction, or by unrequited love. No matter what the context or situation, something is always just a little bit off, or wrong, in each story in this collection, and the characters must do their best to correct the situations.

Few studies exist examining the relationship between self-reported stress and cognitive function in healthy nonpsychiatric older adults, and even less studies have examined whether high levels of self-reported stress accelerate the cognitive decline found in normal late-aging populations. A group of older nonpsychiatric adults, ages 54 years and above, were asked to complete three measures assessing their self-perceived stress over the past month, past year, and their lifetime.

Show moreFew studies exist examining the relationship between self-reported stress and cognitive function in healthy nonpsychiatric older adults, and even less studies have examined whether high levels of self-reported stress accelerate the cognitive decline found in normal late-aging populations. A group of older nonpsychiatric adults, ages 54 years and above, were asked to complete three measures assessing their self-perceived stress over the past month, past year, and their lifetime. Sixty-one adults between the ages of 54 and 88 (52% female) participated in a second phase in which neuropsychological tasks were administered to assess three cognitive domains; memory, learning, and executive functioning. A hierarchical regression examined each of the three domain scores to explore whether self-perceived acute and chronic stress, after covaring for state anxiety, was related to neuropsychological performance. No statistically significant regressions were found, which was predicted for the learning domain, but contrary to the hypotheses for the memory and executive functioning domain. The potential influence of age in this study was explored in a series of ANOVAs examining the interactions between the three stress measures with state anxiety and age on the three cognitive domains. A statistically significant interaction was found between age and perceived lifetime stress when examining the memory domain score. In the young-old participants an increase in stress showed a non-significant relationship with a decrease in memory performance, while in the older-old participants the opposite non-significant tendency was found. The current study also partially replicated an earlier report of a relationship between an increase in recent self-reported stress and a decrease in performance on a specific divided attention task, and extended this finding to include older adults. While the majority of the studyÃÂ's hypotheses were not supported, these preliminary findings provide the field with interesting areas to explore in future studies.

All individuals are members of multiple demographic categories, yet we know surprisingly little about how multiple category membership affects judgments and decision making at work.

Show moreResearch has demonstrated how age stereotypes influence judgment and decision making at work, but older workers are more than just older. All individuals are members of multiple demographic categories, yet we know surprisingly little about how multiple category membership affects judgments and decision making at work. Competing models have been suggested, such as the category activation and inhibition model (Kulik et al., 2007) and the intersectional salience of ageism at work model (Marcus (&) Fritzsche, 2015). However, empirical tests of these models are scarce. In the present study, the age and gender of job applicants were manipulated in a mock job interview. Job context was also manipulated through a recruitment ad that described the ideal applicant using age and gender stereotypic language. One hundred and seventy-three human resource professionals rated the mock interview. It was expected that when the demographic characteristics of the job applicant matched the stereotypes identified by the job ad, hiring professionals would rate the applicant as more suitable in hireability, qualifications, and recommended starting salary. Results showed a bias against older job applicants, as they were rated as less qualified and as requiring higher starting salaries than younger job applicants, even though their interview transcripts were identical. Moreover, a 3-way interaction showed that the highest salaries were suggested for older job applicants whose gender matched the gender stereotypes presented in the job ad. These results illustrate a hurdle faced by older workers; they will be perceived as less capable yet more expensive. Ageism emerged as the most salient category in this study of individuals seeking re-employment beyond traditional working age, but the results suggest intersectional effects as well. Future research should further examine how ageism is experienced by different multi-group members in other job contexts.

Show moreAlthough previous research has focused on subcultures among deviant groups, very little research has been conducted on older adults' subcultures or subcultures within exercise settings. Given the lack of research on older and non-deviant groups, the current research study was designed to reveal how a senior water aerobics exercise class is indeed a subculture and provide a rich description of this understudied and unappreciated subculture. Data collection took place at a water aerobics exercise class at a health club in Central Florida. In the first phase of data collection, ethnographic observations were utilized to identify the social processes in the pool setting. In the second phase of data collection, semi-structured interviews were conducted with 13 seniors to provide a rich description of a water aerobics subculture. Using a constructivist grounded theory approach, the results revealed that the water aerobics class resembles a subculture with distinctive norms, social roles and rituals. Based on these findings, this study concludes that groups such as water aerobics classes may influence seniors' self-esteem, wellbeing and transition into late adulthood.

Show moreThe benefits of being curious continue beyond infancy and early childhood. Curiosity has been linked to academic achievement, memory, and lifelong learning. Yet curiosity type behaviors in academic settings are infrequently observed. This is a concern because some of the students graduating from the educational system will be the teachers responsible for fostering conditions that spark curiosity and exploration for future students. These prospective teachers' lived curiosity experiences will influence their future teaching beliefs and practices. Yet few studies have been conducted that illuminate the lived curiosity experiences of prospective teachers.The research question that guided this study was, what are the lived curiosity experiences of traditionally-aged freshmen pursuing a degree in education? A phenomenological-based approach was chosen to uncover and examine prospective teachers' prior curiosity-related experiences. Using purposive and criterion sampling methods, 13 participants were recruited from foundational education courses. Rich descriptions of participants' curiosity experiences were obtained by conducting semi-structured interviews composed of open-ended questions. Using Moustakas's modified Stevick-Colaizzi-Keen method, data from the verbatim transcriptions were examined and analyzed. Seven themes were extrapolated from the data that were woven throughout four phases of curiosity. The themes revealed that participants' curiosity experiences included exposure to novel information or novel perspectives that sparked feelings or states of being that were both positive and negative. The participants' curiosity prompted them to explore the objects of their curiosity in independent and social activities that were often supported by individuals who provided autonomy and joined them in their exploration. Furthermore, every participant shared at least one experience in which people were the object of their curiosity. People, with whom participants shared a relationship founded on mutual respect and trust, were also instrumental in cultivating conditions that encouraged curiosity and exploration. The findings have implications for researchers, K-12 educators, and individuals responsible for preparing prospective teachers who are interested in exploring further, through research or practice, the potentiality of fostering curiosity.

Show moreThe older population is growing rapidly and businesses must prepare for changes in their workforce. Cases of age discrimination have also become more common. Older workers are being forced out of their jobs at a faster rate than any other age group. As a result, older workers commonly take jobs in different careers, where they compete with younger workers who have similar relevant experience and are valued for their youth. Both prototype matching theory and career timetables theory state that people hold stereotypes of the job in addition to stereotypes of people. In laboratory research, a mismatch between the age of the worker and the age-type of the job has led to lower evaluations, lower job suitability ratings, and other indicators of discrimination. The purpose of this thesis is to assess whether the construct of age-type is related to discrimination in real-world legal cases. Real life instances of discrimination were attained from a 15-year sample of 388 age discrimination jury verdicts and settlements. Each job in the sample of cases was rated to determine age-type, perceived proportion of older and younger workers in the job, and importance of stereotypically older worker features to the job. Results showed that all forms of age stereotypes, both general and specific, were related to the frequency of cases in jobs associated with older or younger stereotypes. Specifically, older workers were more likely to have age discrimination cases go to trial in younger age-typed jobs. However, these variables did not help to predict formal outcomes of the cases (win vs. loss). Among the cases that did win, cases in older age-typed jobs won significantly more money than in younger age-typed jobs.

Show moreAs a writer, I feel like dealing with conflict in real life is the best way to deal with conflict in my fiction. Quarter-Life Crisis or How to Get Over College and Become a Functioning Member of Society, while a fictional novel, is very much about many of the conflicts I've experienced over the past few years. Sean Easton is a twenty-five year old college graduate living in Miami, trying to balance out his life in a world that doesn't make as much sense to him as it did when he first graduated college, happy and looking forward to the future. Suffering through the aftermath of a major breakup as well as the death of his best friend, Sean is in the midst of a year-long alcohol binge when we are introduced to him, a period of time characterized by sporadic bouts of self-loathing interlaced with sardonic internal dialogue directed towards the world at large. Sean's story eventually intersects with the second protagonist in Quarter Life Crisis, Lauren Ellis. Lauren is a twenty-four year old college dropout turned pharmacy technician. When we are introduced to her, Lauren's life is characterized by her child-Justin-and her husband Rick. Rick's a mechanic, and he, Lauren, and their son are all living a comfortably mundane life until the day Lauren comes home to find Rick having sex with eighteen year old Natalie, Justin's babysitter. From there, Lauren's entire life is thrown into disarray, forcing her to confront desires and dreams she had previously filed away in the mental category of "lost." Together, Sean and Lauren represent a large portion of our society, a generation of individuals entering their mid- and late-twenties in the new millennium. Many of them have been told to dream big and aim high throughout their entire lives, that the next four years will be the best of their lives. And then the next four years. A few of us fulfill these dreams. Most don't, and in a time when acquiring a college degree has become more an expectation than an accomplishment, Sean Easton and Lauren Ellis are two of many that are defined by their uncertainty as to where their place in society is. Quarter Life Crisis follows their journey from complete uncertainty to little less uncertain, bringing their lifelong dreams into direct conflict with what they are actually capable of achieving. Though the circumstances of Sean and Lauren's shifts in character are both distinct, their mentality and outlook on love and life are similar. In the end, they both find a balance that gives them hope for happiness which, they both realize, is the most they can really get in the long run. The underlying theme of Quarter Life Crisis or How to Get Over College and Become a Functioning Member of Society is that college has become a fixture in American upbringing. The novel isn't saying this is a good or bad thing, just that it is something that hangs over everybody in the current generation's heads growing up, whether they attend college or not. The novel is an attempt to examine how people function in the new millennium after reaching the point in their life when college is no longer a factor, when they are thrown into the real world and told to fend for themselves. It's the story of how two people end up doing exactly that, and the hellish process they go through to get to that point.

Specifically, I surveyed a national sample of 227 workers 50 years of age and older, in a wide variety of jobs, on measures of perceived age discrimination and adaptation behaviors.

Show moreThis study sought to explore the challenges faced by older workers who do not fit the age-type of their jobs and how older workers adapt to overcome those challenges. Specifically, I surveyed a national sample of 227 workers 50 years of age and older, in a wide variety of jobs, on measures of perceived age discrimination and adaptation behaviors. I found that fit, as determined by career timetables theory, but not prototype matching theory, successfully predicted perceived age discrimination. Specifically, more age discrimination was perceived when fewer older workers occupied a job. Additionally, multiple regression analysis showed that career timetables theory, prototype matching theory, and measures of perceived discrimination interacted to predict adaptation behaviors. That is, older workers made more efforts appear younger at work when they perceived age discrimination in jobs occupied by fewer older workers and older women expressed greater desires to appear younger at work when they perceived age discrimination in jobs viewed as more appropriate for younger workers. Although older workers made a wide variety of efforts to appear younger at work, from changing the way they dressed to undergoing surgical procedures, the adaptation efforts believed to be the most effective against age discrimination were more oriented toward enhancing job performance than one's appearance. It is especially troubling that greater perceived age discrimination was found in young-typed jobs (than in old-typed jobs) given that the number of older workers occupying young-typed jobs is expected to rapidly grow in the near future and perceived discrimination is associated with mental and physical consequences for older adults. Understanding effective adaptations to age discrimination is a valuable first step in helping older workers overcome the disadvantages they may face in the workplace, especially when they occupy young-typed jobs. Implications for theory and research are discussed.

Show moreThe research and statistics gathered in this thesis begin in 2000. Newspapers began experiencing change due to technology before 2000. However, the information necessary to complete this thesis only goes back to that year. Since the year 2000, the newspaper industry has struggled to adapt to the age of ever-changing technology. Newspapers across the US, including large and well-established publications have been forced to find new strategies that allow them to keep up with new digital technologies. The New York Times was the focus of this study, but it is only one part of a very large industry. However, it is one of the most successful papers of the digital age and offers a thorough look into the newspaper industry. Therefore, its strategies to adapt to digital and its overall business model were compared to newspapers throughout the nation. The intent of this thesis is to have a better understanding of the future of the newspaper industry in the digital age, including newspapers in small, medium and large markets. A look into The New York Times' history provides a better understanding of how newspapers have already been affected by the digital age, and its business model offers guidance for other newspapers on how to adapt. This thesis focused on analyzing at least one newspaper to represent each market including a small, medium and large market newspaper then determining if the methods The New York Times uses would be adaptable and scalable to their newspapers. This thesis determines which newspapers could use The New York Times' strategies to their benefit and draws conclusions on the future of the newspaper industry as a whole.
