An Analysis of Travel Trends of the Elderly and Zero-Vehicle Households in the United States

Gorti, Ravi Kiran 06 July 2004 (has links)
The elderly and persons residing in zero vehicle households require better transportation services by virtue of their need for special care and lack of mobility, respectively. An analysis of the travel trends of these population cohorts is essential to determine the best ways to improve transportation facilities to better serve them. Information about location of residence, life-cycle, differences by gender, employment status, driver status, highest level of education coupled with trip information like trip rate, travel times and distances trip purpose, modal split and percent of people immobile will facilitate understanding the factors that influence trip making among these people and help predict travel trends for the future. This work attempts to analyze the elderly and persons residing in zero vehicle households in the United States by using NHTS 2001 and NPTS 1990 datasets for the purpose of analysis and comparison.

Regional Differences in Demographic Characteristics, Professional Practices, and Employment Conditions of School Psychologists Across the United States

Abshier, Dama W 07 July 2008 (has links)
The field of school psychology has grown tremendously within the past 100 years, and legislation has played a major role in many changes related to the field. A review of the literature revealed that many studies have been conducted that explored demographic information, professional practices, and employment conditions. The studies tend to be somewhat narrow in focus (e.g., one study may look at demographic characteristics, while another considers only professional practices) and consider state differences rather than regional differences. In accordance with a policy established by the National Association of School Psychologists (NASP) that a study be conducted every five years, Graden and Curtis (1991) surveyed school psychologists who were members of the NASP for the purpose of developing a national database that reflected the demographic characteristics, employment conditions, and professional practices for the field during the 1989-1990 school year. Members of the NASP have been surveyed relative to the same information every five years since that initial study. The fourth national NASP study was initiated in June of 2005 using data based on the 2004-2005 school year. The database was created using survey data. The present study represented a secondary analysis of the database for the purpose of examining regional differences across the nine U.S. census regions. Regional differences in demographic characteristics, professional practices related to special education, direct and indirect services to students, and employment conditions were analyzed utilizing chi-square analyses and analyses of variance. When significant relationships were found, follow up t-tests were conducted to identify regions between which differences existed. Results indicated statistically significant regional differences for highest degree earned, licensure that allowed for independent practice in non-school settings, the number of re-evaluations conducted, the percentage of ethnic minority students in the district and served, the ratio of students to school psychologists for the district and based on caseloads, the number of days in respondents' contracts, salaries, and percentage of respondents who received clinical supervision.

Investigation of a Consumer's Purchase Intention and Behavior towards Environmentally Friendly Grocery Packaging

Oliver, Mikah Omari 08 1900 (has links)
This study adapted the theory of planned behavior to investigate the relationship between purchase intention and purchasing behavior toward environmentally-friendly grocery packaging. This quantitative study collected 487 useable responses on the Amazon Mturk platform targeting a population of US consumers over 18 years old who purchase groceries. Using the collected data, a correlation and regression analysis was conducted. The socio-demographic variables were used as moderators to investigate the relationship between purchasing intention and actual behavior. The study's results suggest that a consumer's subjective norms substantially stimulate environmentally friendly grocery packaging purchase intentions, which further has or leads to the most decisive influence on actual behavior. Second, we discovered that purchase intention and perceived behavioral control are likely working in conjunction to help bridge the intention-behavior gap in environmentally friendly consumption. Third, this study supplied a fresh perspective on socio-demographics' role in environmentally friendly consumption, confirming that predominantly younger, unmarried consumers are likelier to act upon their intentions by purchasing environmentally friendly grocery packaging. Furthermore, conclusions from this study uncover the primary influences of consumer purchase intention and behavior towards environmentally-friendly grocery packaging. Lastly, but not less important, this study identifies the barriers to environmentally friendly consumption's intention and behavior gap. Results can also give government agencies and brands a clearer perspective to make consumers more knowledgeable on environmentally friendly packaging consumption.

The Employment of Partnered Mothers in Australia, 1981 to 2001

Baxter, Jennifer Anne, Jennifer.Baxter@aifs.gov.au January 2005 (has links)
The employment rate of young partnered women and partnered mothers increased considerably over the 1980s, while there was less change in the 1990s. This thesis explores these changes, with a focus on partnered mothers with young children. The objectives are to describe what the changes in female employment were, and to analyse why they might have occurred. ¶ The analyses were primarily quantitative, although they were put into context with extensive reviews of Australian and, where relevant, international literature. The primary source of data was Australian Bureau of Statistics (ABS) Census data. Other data used included those from the ABS Child Care Surveys, Negotiating the Life Course Survey and the National Social Science Survey. ¶ Many changes in maternal employment were identified. The most notable change was the increase in the number and proportion of partnered mothers working part- time hours. Job characteristics also changed, with these women in full-time or part- time jobs more likely to be working in higher skilled professional and para- professional jobs in 2001, compared to 1981. For partnered mothers with a child aged less than one, the proportion working increased, but there was also evidence that more women were making use of maternity leave. ¶ Coinciding with these changes were a number of compositional changes, as women of succeeding birth cohorts were more educated, and more likely to delay marriage and childbearing. Attitudinal change was also evident, as people became more accepting of working wives. Attitudes to working mothers with young children changed less, with a strong preference for mothers to be at home when their children were young. Also over this period, there were many changes in infrastructure, policy and the labour market generally that had impacts on female employment opportunities and conditions. These changes are explored in detail, and their relationship to employment change examined. ¶ Because there were so many changes in these factors occurring over this period, the exact causes of employment change were difficult to identify. Also, an analysis of employment change is complicated because the causality of certain effects does not run in only one direction – there are more complex links between education, childbearing and employment that should be accounted for in explaining changes over time. Similarly, changes in supply of labour are difficult to disentangle from changes in demand for labour. ¶ Compositional changes were certainly important in explaining the growth in the proportion working, especially for younger women. These women were not only more highly educated in 2001, they were less likely to have children. For working mothers, the effect of increased education levels could be seen in the greater numbers working in higher status occupations. ¶ The analyses of infrastructure and policy change, particularly that of changes in income support and child care provision which were covered in some detail, did suggest that certain aspects of these broader changes were associated with changes in employment, at least for some sections of the population. Income support changes may have enabled more mothers, particularly those in low-income households, to stay at home with young children. This might be part of the reason for the slower growth in female employment in the 1990s, as payments to single-income families increased. ¶ The increased availability of formal child care was likely to have enabled more mothers to work, although the use of informal care, and parental-care only also grew over the 1980s and 1990s. The cost of care continues to be prohibitive for some families. ¶ Increases in part-time work continued even when the overall rate of employment slowed down. Changes in industrial relations, through award restructuring and the introduction of enterprise bargaining, were associated with an increased availability of part-time jobs. This sustained use of part-time work was congruent with the employment preferences of working mothers with young children. Also, the evidence presented shows that part-time work has grown in higher status as well as lower status jobs. ¶ Overall, while it was not possible to identify the exact causes of employment change, the compositional (education and childbearing changes in particular), attitudinal and broader infrastructure/policy changes were no doubt related.

A communication analysis of China's family planning campaigns

Luo, Jianguo, n/a January 1989 (has links)
In China, April 13, 1989 was marked as the "1.1 Billion Population Day." Though it has become the first "demographic billionaire" in the world, China has obtained remarkable results in population control. According to the statement issued by China's National Bureau of Statistics in 1987, the natural population growth rate dropped from 25.83 per thousand in 1970 to 11.28 per thousand in 1985. This has been viewed as an achievement not previously seen in any other population. In the past four decades, the Chinese government has adopted a population policy to organize the fertility transition in a planned way through education, motivation and persuasion. Five communication campaigns have been instituted to implement the policy. The successive family planning campaigns have played a vital role in educating and persuading individuals to accept the new fertility norms advocated by the government. In the communication processes of these campaigns, the strategies used have changed from the media-oriented strategy of the first campaign, to the introduction of an interpersonal approach in the second followed by an integration of media, interpersonal and organisational communication in the three latest campaigns. The integration of the media and interpersonal communication approaches was achieved through group discussion sessions and home visits, in which media messages were mediated and interpreted as a reinforcement to media impact. The group dynamics in the interpersonal communication has played an important role in changing individuals' attitudes towards and behaviour of family planning. As a campaign is an organized activity which requires organizational channels to ensure the conduct of the activity and the flow of information, a well-established organization hierarchy for family planning work has facilitated the management of family planning campaigns and also been regarded as a fundemental element to the success of the later campaigns.

Odor identification in aging and dementia : Influences of cognition and the ApoE gene

Olofsson, Jonas January 2008 (has links)
<p>Olfactory function is impaired in aging and dementia. The general aim of this thesis was to identify variables that predict olfactory function and dysfunction (assessed with an odor identification test) in middle-aged and elderly adults. The thesis investigated whether odor identification performance was associated with demographic variables, cognitive function, the ApoE gene, dementia, and other health-related variables. The ApoE-ε4 allele is associated with cognitive impairment and Alzheimer’s disease, the most common form of dementia. The studies included in this thesis used data from the Betula study, a large-scale, population-based prospective study on aging, memory, and health. Study 1 investigated demographic and cognitive predictors of odor identification ability in non-demented participants. The results showed that younger age, female sex, and high education contributed to better odor identification ability. Cognitive speed and vocabulary had a small additional influence. Study 2 included information about ApoE genotypes, dementia and other health-related variables. The results indicated that the ApoE-ε4 allele was associated with odor identification impairment among the elderly, but not middle-aged adults. Participants who were demented at the time of testing or became demented within five years after testing exhibited olfactory impairments. Interestingly, the age-related olfactory impairment in ε4-carriers was independent of clinical dementia within five years. In Study 3, decline in global cognitive status over a five-year test-retest interval was predicted in a sample of elderly participants. The major result was a three-way interaction reflecting that odor identification impairment, old age, in combination with the ε4 allele predicted a larger cognitive decline. However, odor identification impairment did not predict cognitive change in elderly who were non-carriers of the ε4 allele. Overall, the results indicate that odor identification impairment in elderly is related to ApoE-ε4, cognitive decline, and clinical and pre-clinical stages of dementia. Theoretical and practical implications of the results are discussed. Furthermore, it is proposed that in order to effectively predict clinical dementia or cognitive decline from olfactory assessment in the elderly, variables that mediate (e.g. neuropathology) or moderate (e.g. age) the associations between olfactory function, the ε4 allele, and dementia need to be further evaluated, preferably in studies using longitudinal assessment.</p>

The Green Consumer : A Study of Income and Organic Consumption / Den gröna konsumenten : En studie om inkomst och ekologisk konsumtion

Jakobsen, Emma, Svensson, Maja January 2008 (has links)
Organic consumption is currently experiencing a boom of sales on the Swedish and international market. Whether this occurrence is a contemporary trend or if it will prove to be sustainable in the future, the demographics of the so-called ‘green consumer’ are of great interest for economic agents on markets such as foods and textiles. Therefore, the writers have chosen to highlight this topic by focusing on the relation between income and purchase of organic products.. Economic data for the Swedish market has been gathered and analyzed through various statistical and macroeconomic perspectives, where the basis has been Kelvin Lancaster’s models of consumer choice theory. The results showed that income does not generally have a direct effect on the choice of purchasing an organic good in Sweden, although it cannot be fully dismissed when discussing the demographics of the green consumer. Other factors are of importance as well, including education, marital status and geographical location. The study of the green consumer is a rather new area and this study, along with its previous counterparts, has proved it difficult to draw any firm conclusions regarding the characteristics of the organic consumer. Therefore, future studies within this area will have plenty to discover about a subject of increasing interest and importance on the market. / Ekologisk konsumtion upplever för närvarande en försäljningsboom på den svenska och internationella marknaden. Oavsett om detta är en tillfällig trend eller om det kommer bestå såväl i framtiden, är demografierna av de såkallade ’gröna konsumenterna’ av stort intresse för ekonomiska agenter inom marknader såsom textil och dagligvaror. Därför har författarna valt att framhäva detta ämne genom att fokusera på relationen mellan inkomst och inköp av ekologiska produkter. Ekonomisk data för den svenska marknaden har samlats in och analyserats genom olika statistiska och makroekonomiska perspektiv, där basen har varit Kelvin Lancasters modeller av konsumentteori. Resultaten har visat på att inkomst generellt inte har en direkt effekt på valet att köpa en ekologisk vara i Sverige, även om denna faktor inte helt kan uteslutas när demografier av den gröna konsumenten diskuteras. Andra faktorer har också betydelse, däribland utbildning, civilstånd och geografisk lokalisering. Studier om den gröna konsumenten är ett relativt nytt område, och denna kandidatuppsatsen har, tillsammans med föregående rapporter inom ämnet, funnit det svårt att dra några fasta slutsatser om den ekologiska konsumentens karaktärer. Därför kommer framtida studier inom detta område ha mycket att upptäcka om ett ämne av ökande intresse och angelägenhet på marknaden.

Quality of life among persons aged 60-84 years in Europe: The role of psychological abuse and socio-demographic, social and health factors

Soares, Joaquim JF, Sundin, Örjan, Viitasara, Eija, Melchiorre, Maria Gabriella, Stankunas, Mindaugas, Lindert, Jutta, Torres-Gonzales, Francisco, Barros, Henrique, Ioannidi-Kapolou, Elisabeth January 2013 (has links)
Background: Elder abuse and its effects are a serious public health issue. However, little is known about therelation between psychological abuse, other factors (e.g. social support) and quality of life (QoL) by domain. This studyaddressed differences in QoL by domain between psychologically abused and non-abused. While considering otherfactors such as social support. Methods: The respondents were 4,467 (2,559 women) randomly selected persons aged 60-84 years living in7 European cities. The mean response across countries was 45.2%. The cross-sectional data were analyzed withbivariate/multivariate methods. Results: Abused respondents contrasted to non-abused scored lower in QoL (autonomy, 67.42 ± 21.26 vs. 72.39± 19.58; intimacy, 55.31 ± 31.15 vs. 67.21 ± 28.55; past/present/future activities, 62.79 ± 19.62 vs. 68.05 ± 18.09;social participation, 65.03 ± 19.84 vs. 68.21 ± 19.77). Regressions showed that abuse was negatively associated withautonomy, intimacy and past/present/future activities, and positively with the social participation. All QoL dimensionswere negatively associated with country and depressive/anxiety symptoms, and positively with social support. Further,variables such as age, sex and somatic symptoms were negatively associated with some of the QoL dimensions andothers such as family structure, education, health care use and drinking positively. The regression model “explained”32.8% of the variation in autonomy, 45.6% in intimacy, 44.8% in past/present/future activities and 41.5% in socialparticipation. Conclusions: Abuse was linked to lower QoL in most domains, but other factors such as depressive symptomsalso carried a negative impact. Social support and to some extent family structure had a “protective” effect on QoL.Abuse, health indicators (e.g. depressive symptoms) and social support should be considered in addressing the QoL ofolder persons. However, QoL was influenced by many factors, which could not be firmly disentangled due to the crosssectionalapproach, calling for longitudinal research to address causality.

Managerial Demographics: Measurement and Implications for the Innovation Performance of Manufacturing Firms

Sharma, Asmita 01 February 2013 (has links)
The present study addresses the perceived gap in literature on contribution of managerial demographics to the innovation performance of manufacturing firms of 12 European countries so as to highlight the distinctive role of managers in a broader context. The managerial demographics is conceptualised as the managerial knowledge(education and experience), gender role (number of female managers), leadership role (top manager's years of experience) and, management ratio. The effect of managerial demographics is examined on two dimensions of innovation performance: first, the propensity of firms to perform innovation and, second, the innovation intensity of firms. We report that the role of female managers in innovation is more significant, than that otherwise emphasised in innovation literature, as evident in case of countries under study. And, the number of female managers have a positive impact on the innovation performance of manufacturing firms. Moreover, the results show that managerial experience also have a non-linear effect on the innovation performance of manufacturing firms. Finally, the implications of the findings are discussed in-detail.
