Explorations with Polycarbocyclic Cage Compounds

Explorations with Polycarbocyclic Cage Compounds

Date: August 1999
Creator: Chong, Hyun-Soon
Description: A variety of novel cage-functionalized pyridyl containing crown ethers have been prepared for use in selective alkali metal complexation studies. A highly preorganized, cage-functionalized cryptand also has been designed and has been synthesized for use as a selective Li+ complexant. The alkali metal picrate extraction profiles of these cage-functionalized crown ethers also have been studied. Novel cage-functionalized diazacrown ethers have been prepared for selective alkali metal complexation studies. Alkali metal picrate extraction experiments have been performed by using this new class of synthetic ionophores to investigate the effects of cage-annulation and the influence of N-pivot lariat sidearms upon their resulting complexation properties. Novel pyridyl containing calix[4]arene receptors were prepared. Analysis of their respective 1H NMR and 13C NMR spectra suggests that calix[4]arene moieties in the ligand occupy the cone conformation. The complexation properties of these host molecules were estimated by performing a series of alkali metal picrate extraction experiments. An optically active cage-functionalized crown ether which contains a binaphthyl moiety as the chiral unit was prepared. The ability of the resulting optically active crown ether to distinguish between enantiomers of guest ammonium ions (i.e., phenylethylamonium and phenylglycinate salts) in transport experiments was investigated. Hexacyclo[11.2.1.02,12.05,10.05,15.010,14]hexadeca-6,8-diene-4,11-dione was prepared from hexacyclo[7.4.2.01,9.03,7.04,14.06,15] pentadeca-10,12-diene-2,8-dione. Unanticipated ...

Exploratory Analysis of Social E-health Behavior

Exploratory Analysis of Social E-health Behavior

Date: May 2014
Creator: Acadia, Spencer
Description: Extant literature has documented well that people seek health information via the internet as patients and consumers. Much less, however, is known about interaction and creation behaviors in the development of new online health information and knowledge. More specifically, generalizable sociodemographic data on who engages in this online health behavior via social media is lacking in the sociological literature. The term “social e-health” is introduced to emphasize the difference between seeking behaviors and interaction and creation behaviors. A 2010 dataset of a large nationally representative and randomly sampled telephone survey made freely available from the Pew Research Center is used to examine social e-health behavior according to respondents’ sociodemographics. The dependent variable of social e-health behavior is measured by 13 survey questions from the survey. Gender, race, ethnicity, age, education, and income are used as independent variables. Logistic regression analysis was used to determine the odds of engagement in social e-health behavior based on the sociodemographic predictors. The social determinants of health and digital divide frameworks are used to help explain why socioeconomic variances exist in social e-health behavior. The findings of the current study suggest that predictable sociodemographic patterns along the dimensions of gender, race, age, education, and income ...

An Exploratory Analysis of the Food Consumption Behavior of Up-scale Asian-American Consumers

An Exploratory Analysis of the Food Consumption Behavior of Up-scale Asian-American Consumers

Date: August 1993
Creator: Boykin, Nancy J. (Nancy Jo)
Description: The first objective of this research was to identify whether Asian-Americans having higher than average levels of income and education represent an appropriate target market for four food product categories. Second, the impact of national origin membership, demographic variables, and level of acculturation on food consumption was determined. In addition, perceptions related to sensory and nutritional factors and the cultural acceptability of the products were identified and interpreted to determine if the variables differed among specific groups of Asian-American consumers.

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

Exploratory and Confirmatory Factor Analysis of the Clinical Scales of the Luria-Nebraska Neuropsychological Test Battery, Form II

Date: May 1990
Creator: Nagel, Jeffrey A.
Description: The factor structure of the Luria Nebraska Neuropsychological Battery (LNNB) Form II was examined. A principle components factor analysis was performed on a sample of 102 psychiatric and neurologic subjects. It was necessary to remove 45 items from the analysis due to perfect performance by most subjects. The results were orthogonally rotated to simple structure using a Varimax method of rotation, and then compared to previous LNNB Form I and Form II results. Thirty-three factors were generated in the Exploratory Factor Analysis (EFA) . There was a very high agreement with the factors from Form I. Only one new factor was identified that didn't have a comparable Form I factor, and this factor appears to have neurological support. The similarity of the factor solutions between the two forms supports the continued use of factors derived from Form I for the interpretation of Form II, and supports the underlying structure presupposed by Lurian constructs. The present study also tested the significance of the hypothesized factor structures through confirmatory factor analysis (CFA). No hypothesis about the underlying factor structure based on previous exploratory studies was supported. The CFA did suggest that the best factor solution to the LNNB Form II is one ...

An Exploratory Empirical Investigation of Information Processing among Incubator-Housed Manufacturers during Channel Member Selection

Date: December 1988
Creator: Fontenot, Gwen F.
Description: The purpose of this research was to conduct an exploratory study of the information processing utilized by incubator-housed manufacturers during channel member selection. The study included the evaluation of the decision models used by the manufacturers as well as criteria used in the selection process. The study was specifically designed to achieve the following objectives. First, the research was to identify the evaluation modes used by the manufacturers as either compensatory or noncompensatory. Second, the study was to evaluate the effect of the task on the selection of the evaluation model(s) used during the channel member selection process. Third, the study was to evaluate the effect of the selected decision strategy on the amount of information used during the decision process. Finally, the study was to identify and examine the importance of the criteria used by the manufacturers in the selection process. The methodology in this study consisted of primary research using protocol analysis as the main data gathering technique. A ranking instrument was also mailed to the respondents prior to the protocol session. The population for the study was identified as all manufacturers located in publicly-sponsored business incubators. A total of 235 incubators were in existence with approximately 47 ...

Exploratory Factor Analysis of the Geriatric Depression Scale Among Cardiac Patients

Exploratory Factor Analysis of the Geriatric Depression Scale Among Cardiac Patients

Date: May 1998
Creator: Hupp, Gregory S.
Description: The Geriatric Depression Scale (GDS) was originally designed as a measure for screening depression among elderly medical patients. Although this instrument is well validated among a general medical population, it has never been evaluated with specific regard to cardiac patients, the largest single group of medical patients over 40 years of age. A general cardiac sample of 655 patients completed the GDS within 10 weeks of the cardiac event. Exploratory factor analyses were conducted on the main sample, then on several subgroups of participants with regard to diagnostic category, gender, and age. The GDS generally produces factor structures with several symptom domains with a high rate of total variance. The myocardial infarction group endorsed general symptoms of depression whereas the coronary artery bypass graft group reported greater levels of despair regarding their condition. Overall, males primarily reported agitation and hopelessness while females reported symptoms of depressed mood.

An Exploratory Field Study of Adolescent Consumer Behavior: The Family Purchasing Agent

An Exploratory Field Study of Adolescent Consumer Behavior: The Family Purchasing Agent

Date: August 1989
Creator: Hardy, Jane P.
Description: An exploratory field study was conducted to examine internal and external factors that influence adolescents' consumer behavior when serving as the family purchasing agents. Demographic, lifestyle, and marketing activities were examined to determine the influences that affect whether the adolescent will purchase the preferred family brands or other brands. Participating adolescents were sent by their parents to the grocery store on two separate occasions to purchase four preselected grocery items. The brands purchased were recorded and compared to the preferred brand names provided by the parents. While no statistical significance was found, occasional trends were observed. The analysis indicated that adolescents who experience a pluralistic family communication style will purchase products other than the preferred household brands. Adolescents who are exposed to television and radio tend to deviate more from the preferred family brands more often than do adolescents with less media exposure. Adolescents who work are more likely to go to the grocery store more often for their families than do nonworking adolescents. Also, adolescents seem to possess a price sensitivity to both high and low-involvement grocery items.

An Exploratory Investigation of Marital Role Expectations and their Relationships to Perceived Parent-Child Relations and Perceived Family Integration

An Exploratory Investigation of Marital Role Expectations and their Relationships to Perceived Parent-Child Relations and Perceived Family Integration

Date: May 1973
Creator: Hopewell, Clifford Alan
Description: Fifty-one male and 57 female college undergraduate students enrolled in an introductory psychology course responded to the Roe-Siegelman PCR Questionnaire, a modified form of Tharp's (1963b) Marital Role Expectation Form (MRE), and a Family Integration Scale as fulfillment of research participation requirements. Previous research had indicated that generally children who experienced love and warmth in their childhood home had marital role expectations of friendliness, spontaneity, adaptability, trust, responsibility, and leadership, while those who experienced rejecting and neglecting parental behaviors were more likely to have expectations of being seclusive, guilty, hostile, rigid, mistrustful, and irresponsible.

An Exploratory Investigation of Socio-Economic Phenomena that May Influence Accounting Differences in Three Diverse Countries

An Exploratory Investigation of Socio-Economic Phenomena that May Influence Accounting Differences in Three Diverse Countries

Date: August 1989
Creator: Hudack, Lawrence R. (Lawrence Ralph)
Description: This dissertation attempts to provide an exploratory structure to respond to, and tries to resolve, an existing void in international accounting research. The void is a lack of coherently structured, nation-specific, descriptive research to investigate socio-economic phenomena which may influence financial accounting. This dissertation's salient features include a political economy theory, an exploratory, sociological method, and a case study format. The political economy of accounting, introduced by Tinker [1980] and refined by Cooper and Sherer [1984], emphasizes a persuasive social relations dimension. This theory motivates selection of three countries (the United States, France, and Japan) that appear to have divergent socio-cultural environments. An exploratory and analytical approach of modified (enlarged) exogenism, developed by Smith [1973, 1976] and adapted to accounting by McKinnon [1986], provides an analytic structure for this exploratory investigation. Modified exogenism focuses upon an open, dynamic social system (the process of financial accounting), and provides analysis reflecting four major areas (the environment, intrusive events, intra-system activity, and trans-system activity). After examining the nation-specific financial accounting (socio-economic) structures for each country, an analysis of selected financial disclosures attempts to gain a better understanding of how socio-economic factors have influenced the development of financial accounting. My primary objective is to ...

An exploratory investigation of the effects of co-production and co-consumption on the characteristics and adoption of service innovations: the customer's perspective.

An exploratory investigation of the effects of co-production and co-consumption on the characteristics and adoption of service innovations: the customer's perspective.

Date: August 2007
Creator: Zolfagharian, Mohammadali
Description: Customers play an active role throughout the marketing process. This dissertation concerns itself with customer's co-creation of value for self (co-production) and for other customers (co-consumption) during service production and delivery. With the servuction system as its overarching framework, this study explains how changes in the customer's perceived co-production and co-consumption, caused by a service innovation, influence her perceptions of service innovation characteristics and modify her adoption behavior. It draws on a multidisciplinary body of knowledge and develops a conceptual framework and a set of substantive propositions. The empirical research was contextualized in three services: self check-out at grocery stores, Build-A-Bear stores, and meal assembly centers. It focused on members of Generations X and Y who were familiar with these services. The qualitative investigations and pilot study helped adapt the extant scales and construct new scales. In line with prior works, the focal service encounters were simulated through a series of consumption scenarios. The exploratory factor analysis in the pilot study and the confirmatory factor analysis in the main study indicated that the instruments were culturally informed, internally reliable, and construct-wise valid. The results indicate that co-production and co-consumption play important roles in explaining innovation characteristics and adoption decisions. More ...

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

An Exploratory Investigation of the Origins and Regulatory Actions of the United Kingdom's Financial Reporting Review Panel

Date: December 1998
Creator: Styles, Alan K. (Alan Keith)
Description: In 1990, the accounting profession and the British government worked together to establish a new regulatory framework for financial reporting in the United Kingdom (UK), the Financial Reporting Council (FRC) and its two subsidiaries, the Accounting Standards Board (ASB) and the Financial Reporting Review Panel (FRRP). The FRRP enforces companies' compliance with the ASB's accounting standards and the accounting provisions of the UK Companies Act. Only one study, Brandt et al. (1997), has examined the activities and effectiveness of the FRRP. This dissertation attempts to extend Brandt et. al (1997) and add to understanding of the origins and regulatory actions of the FRRP.

An Exploratory Study of Factors Influencing the Effectiveness of the Amob/vll Program for Participants in North Central Texas

Date: December 2011
Creator: Ewing, Charles W.
Description: This study assessed falls efficacy and confidence-related changes among participants attending the a Matters of Balance/Volunteer Lay Leader (AMOB/VLL) falls prevention program for older adults, based on their residential location. Data were examined from 431 older Texans enrolled in AMOB/VLL during a two-year period, and assessed at baseline and post-intervention. Results indicate that participants significantly increased falls efficacy, reduced activity interference due to their health, and decreased the number of days limited from usual activity. Regression models show that participants, despite entering the program with lower reported health status, reported greater rates of positive change for falls efficacy and health interference compared with their baseline pre-intervention counterparts. Overall program attendance and attendance at major sessions showed the greatest influence. Findings contribute to the understanding of cognitive restructuring and strengthening variations with falls prevention program outcomes.

An exploratory study of factors that influence student user success in an academic digital library.

An exploratory study of factors that influence student user success in an academic digital library.

Date: December 2007
Creator: Rahman, Faizur
Description: The complex nature of digital libraries calls for appropriate models to study user success. Calls have been made to incorporate into these models factors that capture the interplay between people, organizations, and technology. In order to address this, two research questions were formulated: (1) To what extent does the comprehensive digital library user success model (DLUS), based on a combination of the EUCS and flow models, describe overall user success in a prototype digital library environment; and (2) To what extent does a combined model of DeLone & McLean's reformulated information system success model and comprehensive digital library user success model (DLUS) explain digital library user success in a prototype digital library environment? Participants were asked to complete an online survey questionnaire. A total of 160 completed and useable questionnaires were obtained. Data analyses through exploratory and confirmatory factor analyses and structural equation modeling produced results that support the two models. However, some relationships between latent variables hypothesized in the model were not confirmed. A modified version of the proposed comprehensive plus user success model in a digital library environment was tested and supported through model fit statistics. This model was recommended as a possible alternative model of user success. ...

An Exploratory Study of Restaurant Multi-unit Managers’ Development

An Exploratory Study of Restaurant Multi-unit Managers’ Development

Date: May 2014
Creator: Lentz, Kathryn J.
Description: Development is important to the initial phase of a new restaurant multi-unit manager (MUM), and appropriate training should be conducted in concert with acceptance of the position. The purpose of this study is to explore the need for individual training of restaurant MUMs in order to facilitate a smoother transition between executive level management positions. The exhaustive literature review aided in the creation of three research questions to be answered through the interpretation of collected interview data. Restaurant MUMs were invited to participate via LinkedIn, a social media network for professionals. Semi-structured interviews were conducted with 17 restaurant MUMs over a two-week period and then transcribed into Word documents and uploaded into ATLAS.ti for analysis. The use of tools within ATLAS.ti, such as network mapping and semantic layouts, allowed the researcher to interpret the correlation between codes and themes created and therefore, answer the research questions. Conventionally, managers have to leave their restaurants or area for many days in order to obtain the necessary training to be more effective in their positions. This study has concluded that while MUMs are aware of their tasks and responsibilities, they are not aware of training available in order to gain the skillset necessary ...
