Households experiencing residential satisfaction are joint headed, homeowners residing at their current dwelling for a long duration, well integrated within the community, and possessing low intraurban mobility, high percent of dependents, low crowding, high incomes, and low percent of adults employed. Households satisfied with their community are home renters residing at their current dwelling for a short time and who have experienced downward residential mobility; they have high incomes, low percent of employed adults, and are socially integrated. Finally, mobility plans are positively shaped by high intraurban mobility, homeownership, low housing type mobility, high crowding, residential improvements, high level of ...


Dimensions Of Life Events And Difficulties As Predictors Of The Onset Of Major Depression , Michelle Jacqueline Freedman Jan 2000

Dimensions Of Life Events And Difficulties As Predictors Of The Onset Of Major Depression , Michelle Jacqueline Freedman

Retrospective Theses and Dissertations

The primary purpose of this dissertation was to examine whether life events and difficulties increase the risk of onset of major depression. Life events and difficulties were measured using the Structured Life Events Inventory (SLI), a more structured version of the open-ended, semi-structured Life Events and Difficulties Schedule (LEDs). In addition, several characteristics of life events and difficulties were tested in an attempt to better understand which aspects of these stressors were particularly important in risk for the onset of depression. Also, the psychosocial resources of perceived social support and sense of personal control were examined to determine their effect ...


Post-Solidarity And Postmodern Intergenerational Relation(Ship)S , Michael-David Alphonsus Rodriguez Richardson Kerns Jan 2000

Post-Solidarity And Postmodern Intergenerational Relation(Ship)S , Michael-David Alphonsus Rodriguez Richardson Kerns

Retrospective Theses and Dissertations

An alternative set of constructs for intergenerational relation(ship)s, Post-Solidarity, is presented and empirically tested. Post-Solidarity comprehends not only traditional positive and consensual dimensions of within-primary-group (or "family") relation(ships) but also the ambivalence, conflict, fluidity, and indeterminacy so characteristic of social life in Postmodern America (and, perhaps, Western Europe). A series of measurement, mean-comparison, and regression analyses, evaluating the nomothetic and predictive viability of Post-Solidarity against the currently dominant conceptualization of intergenerational relation(ship)s as either solidary or fatally conflictual, generated results that suggest preliminary support for Post-Solidarity as an additive and more appropriate conceptualization of contemporary ...


Alcohol Use And Abuse Among College Women: A One-Year Follow-Up Study , Jennifer Lynne Miller Jan 2000

Alcohol Use And Abuse Among College Women: A One-Year Follow-Up Study , Jennifer Lynne Miller

Retrospective Theses and Dissertations

Is drinking among college women a relatively harmless phase, or does it point to longer-term problems? A sample of women (N = 149) from a large Midwestern university were surveyed about their alcohol use one year after they first completed an alcohol questionnaire. Approximately half of the sample (N = 70) were identified as alcohol abusers at Time 1, and the other half of the sample (N = 79) served as a control group. The two groups were compared on the average number of drinking occasions, average amount of alcohol consumed, number of binge drinking occasions in the last two weeks, and number ...

Acculturation And Cultural Value Orientations Of Immigrant Chinese Americans: Effects On Body Image, Aesthetics For Appearance, And Involvement In Dress , Ching-Yi Cheng

Retrospective Theses and Dissertations

The research was an investigation of the effects of acculturation and cultural value orientation on individuals' body image, aesthetics of appearance, and dress involvement. The surveys were completed by immigrant Chinese Americans that consisted of women (n = 124, 59%), men (n = 82, 40%), and three participants who did not state gender. A majority of the participants were born in Taiwan (64%), China (28%), and Hong Kong (8%). The majority of respondents were classified as "unacculturated" (55%) or "bicultural" (44%); only 1% as "acculturated." With regard to their value orientation, the majority were "collectivism oriented" (32%) or "bi-value oriented" (64%);Results ...


Overfitting And Forecasting: Linear Versus Non-Linear Time Series Models , Yamei Liu Jan 2000

Overfitting And Forecasting: Linear Versus Non-Linear Time Series Models , Yamei Liu

Retrospective Theses and Dissertations

The main purpose of this dissertation is to compare the in-sample estimating and out-of-sample forecasting performance of a set of non-linear time series models, i.e., threshold autoregressive models, momentum threshold autoregressive models, exponential autoregressive models, generalized autoregressive models and bilinear models. First, a Monte Carlo simulation is used to study overfitting and forecasting. For AR processes, if the AIC and SBC criteria are used to select models, the possibility of overfitting is very high since the non-linear models and other linear models are very likely to have lower AIC and SBC. However, the MSPE for one-step ahead out-of-sample forecast ...

An Examination Of The Evolving Relationship Between Interest Rates Of Different Maturities In Japan, And Test Of The Expectations Hypothesis Of The Term Structure To Ascertain The Feasibility Of Using Asymmetric Dynamics In Yield Spreads , Shew-Huei Kuo

Retrospective Theses and Dissertations

The purpose of the study was to examine the evolving relationship between interest rates of different maturities in Japan, allowing for possible asymmetrical movements toward a long-run equilibrium rather than use of the traditional analysis of symmetrical movements. The relationship among interest rates of different maturities has been extensively studied with mixed results. This research provides empirical evidence concerning the properties of interest rate term structure using Japan's data from 1980 to 1998. The study employed the testing methodologies which permit asymmetry in the adjustment toward equilibrium in the threshold autoregressive and the momentum-threshold autoregressive specifications. The test results ...

The following nine themes emerged from the data: (1) "maternal" sacrifice, (2) bearing the emotional labor of caring for children, (3) pressures/expectations of mothering, (4) mothers' connections to their children, (5) mother/father differences in parenting and the influence of the marital relationship, (6) issues of loss surrounding motherhood, (7 ...


Psychosocial Factors In Marital And Family Relationships Associated With Physical Illness: A Case For Collaborative Health Care , Clifford Stanley Jernigan Jan 2000

Psychosocial Factors In Marital And Family Relationships Associated With Physical Illness: A Case For Collaborative Health Care , Clifford Stanley Jernigan

Retrospective Theses and Dissertations

In the diagnosis and treatment of physical illness, limited attention is given to psychosocial factors related to the etiology, pathogenesis, and treatment of symptoms. Over the past thirty years, however, practitioners have increasingly begun to acknowledge the importance of psychosocial factors to the assessment, diagnosis, and treatment of apparently biomedical symptoms. DSM-IV alludes to psychological factors affecting a person's medical condition, and thereby infers an association between the factors and physical illness. Understanding the connection between biomedical and coexisting mental symptoms may provide new cues to a more accurate diagnosis and treatment of organic as well as mental disorders ...

Blame For Past Behavior Versus Threat To Future Freedom: Reaction To Anti-Binge Drinking Messages , Monica Joy Reis-Bergan Jan 2000

Blame For Past Behavior Versus Threat To Future Freedom: Reaction To Anti-Binge Drinking Messages , Monica Joy Reis-Bergan

Retrospective Theses and Dissertations

Past research has established that losing one's freedom to act results in arousal and increased motivation to do the restricted behavior (Brehm, 1966). However, in cases where the individual has previously engaged in the behavior the message also contains an implicit message of blame. To date, no experimental studies have been conducted to separate the influence of these two messages. The current study examined the impact of message characteristics on health cognitions related to binge drinking. The primary goal was to investigate the role of blame for previous excessive consumption and demand for future behavior change on health cognitions ...

Retrospective Theses and Dissertations

The purpose of the current research was to study the interhemispheric interaction in the brains of mathematically gifted youth, average ability adolescents, and college students. This study investigated the efficiency of interhemispheric interaction via the corpus callosum for brief displays of hierarchical stimuli under these conditions: (1) when both hemispheres have direct access to the visual information for performing global/local matches (i.e., bilateral redundant trials), (2) when the information necessary to perform such matches is divided between the visual-fields/hemispheres, thus forcing the hemispheres to exchange information to successfully perform the task (i.e., bilateral cooperative trials), and ...


Purchasing Power Parity And Uncovered Interest Parity: Another Look Using Stable Law Econometrics , Chun-Hsuan Wang Jan 2000

Purchasing Power Parity And Uncovered Interest Parity: Another Look Using Stable Law Econometrics , Chun-Hsuan Wang

Retrospective Theses and Dissertations

In this study, we will re-examine the long-run PPP and UIP relationships by using standard cointegration test procedures but with critical values that are appropriate under infinite variance errors. These tests are performed using monthly observations over the period January 1973--December 1999 for Belgium, Canada, Denmark, France, Germany, Italy, Japan, Netherlands, Norway, Spain, Sweden and United Kingdom against the United States;Finite variance errors are a basic assumption for the distribution theory used to evaluate test statistics for the analysis of cointegration in PPP and UIP. But some recent studies have suggested that many financial variables, such as exchange rate ...

These benefits or willingness-to-pay for improved environmental practices have been obtained through research using a multiple trial second-price sealed-bid auction;A focus of ...


Economic Issues In Resistance Management , Silvia Secchi Jan 2000

Economic Issues In Resistance Management , Silvia Secchi

Retrospective Theses and Dissertations

This dissertation analyzes economic issues related to the use of agricultural pesticides and antibiotics. The efficacy of both these chemical compounds depends on the existence of susceptible targets. However, through natural selection, their utilization increases the frequency of the genes resistant to the pesticide or drug in the target population, and it decreases the available biological capital of genetic susceptibility, increasing resistance;The aim of this dissertation is to analyze the characteristics of optimal resistance management strategies. An empirical analysis is offered in case of bioengineered Bt corn, which underlines the importance of pest mobility, and the externalities it causes ...

Exogenous model elements included socio-economic status, math problem solving achievement, math concepts achievement, motivation for learning math, and score on math exemplar one. Endogenous variables ...


Failing To Find Context-Dependency In Perceptual Implicit Memory: Evidence Against An Episodic View? , Brian Thomas Crabb Jan 2000

Failing To Find Context-Dependency In Perceptual Implicit Memory: Evidence Against An Episodic View? , Brian Thomas Crabb

Retrospective Theses and Dissertations

This dissertation tested the hypothesis that perceptual implicit memory is affected not just by the prior perceptual processing, but also by prior decisions resulting from the perceptual processing. According to the proposed view, three aspects of the context can potentially affect the level of perceptual implicit memory---the physical context (what are the surroundings in which the stimulus occurs and a decision is made?), the decision processing context (what kind of decision is being made about the stimulus?), and the response context (what action is taken based upon the decision that is reached?);Three predictions of the proposed view were tested ...


Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen Jan 2000

Agricultural And Trade Policy Reform In Mexico: Procampo, Nafta, And Pre-Gatt , James Mark Hansen

Retrospective Theses and Dissertations

Changes in Mexico's domestic agricultural policy (PROCAMPO) and continued liberalization of trade through GATT and NAFTA have had strong effects on Mexico's agricultural production, consumption, and trade with the United States. The main objective of this study is to analyze these effects in Mexico's grain and livestock sectors. Policies within the NAFTA and GATT international trade agreements may overlap to some degree, and Mexico's domestic agricultural liberalization program (PROCAMPO) may include policies that overlap those in one or both of the international trade agreements. This study analyzes the effects of PROCAMPO, NAFTA, and pre-GATT policies compared ...

The Organizational Choice Of Public Good Provision , Chia-Yen Yang Jan 2000

The Organizational Choice Of Public Good Provision , Chia-Yen Yang

Retrospective Theses and Dissertations

This dissertation maintains that organizational efficiency and interest competition are the two primary forces of institutional formation for the public good provision. On the one hand, efficient institutions are in principle desirable, since they bring about potential gains for the involved interests as a whole. On the other, interest conflict in distributing the potential gains may lead to the emergence of some alternatives that appear relatively inefficient. The perceived institutional inefficiency, however, comes from neglecting the fact that settling distribution disputes is frequently costly in the human society. In this dissertation, a comprehensive organizational classification is proposed in terms of ...

Introducing Change: A Rhetorical Analysis Of The Early Communications In Mergers And Acquisitions , Janel M. Bloch

Retrospective Theses and Dissertations

Change and uncertainty are integral elements of any organization, yet they are not easy to face and they elicit a wide range of responses among organizational members. This study uses a rhetorical approach to examine the communications directed to employees in one type of organizational change---mergers and acquisitions;Based on a review of the mergers and acquisitions, management, organizational behavior, and rhetoric and professional communication literature, I identify four major rhetorical challenges that need to be addressed in the early communications in mergers and acquisitions: setting the stage for cultural change, addressing emotions, dealing with uncertainty, and building an identity ...


Integrating Multicultural Education And Computer-Mediated Communication: Opportunities And Challenges , Lucretia Orlantha Carter Jan 2000

Integrating Multicultural Education And Computer-Mediated Communication: Opportunities And Challenges , Lucretia Orlantha Carter

Retrospective Theses and Dissertations

In response to national and international agendas of globalization, a number of educators are exploring the integration of multicultural education and computer-mediated communication (CMC) as a promising practice for meeting requests of educational reform. The popular belief is that the cause and goals of multicultural education can be served by CMC, due to its ability to foster access to and cultivate the development of previously unavailable, dynamic, self-sustaining learning communities. While this practice is predicted to continue, currently research in this area is sparse and existing research leaves much to question about the validity of the practice;Seeking to gain ...

Comparison Of Macro And Micro Observational Methods For Measuring Marital Social Support , Krista Kay Krebs Jan 2000

Comparison Of Macro And Micro Observational Methods For Measuring Marital Social Support , Krista Kay Krebs

Retrospective Theses and Dissertations

This study examined the predictive utility of two observational measurement methods for examining marital social support. Eighty-two married couples completed self-report measures, and 10 minute videotaped supportive interactions. The interactions were designed to elicit discussion of current problems that were outside the couple's marital relationship. The first method of measurement was a macro-observational method---the Iowa Family Interaction Rating Scales (IFIRS: Melby et al., 1993), based on global ratings of the couples' interactions that fit descriptions of listener responsiveness, warmth, and hostility. The second method was a micro-observational method---the Social Support Behavior Code (SSBC: Suhr, 1990; Cutrona & Suhr, 1992, 1994 ...
