Identity issues in Asian-American children's and adolescent literature (1999-2007).

Identity issues in Asian-American children's and adolescent literature (1999-2007).

Date: December 2009
Creator: Liu, Yi-chen
Description: Published research suggests that literature should transmit ethnic and societal values as well as reassure one's own confidence and self-respect. This study provides a model for examining Asian-American children's and adolescent literature critically from the perspective of identity issues. It examines fifteen award-winning Asian-American children's and adolescent titles written by writers of that culture and published in the United States from 1999 to 2007, with a focus on Chinese (Taiwanese) American, Korean American, and Japanese American books. As published studies indicate, self, social, and ethnic identities are significantly intertwined. Hence, a content analysis was conducted based on these three major groups of categories. The findings of the study demonstrate that even though the selected books cover all three aspects of the identity issues to a certain degree, a considerably greater number of depictions of ethnic identities are made over those of internal identities and social identities. Moreover, less than half of the main characters assume an active role in improving the difficult situation. Two major voids regarding the presentation of social identities are successful social integration and positive social interactions. Recommendations for teaching, writing, illustrating, publishing, and future research are suggested, including publishing more Asian-American books which present an optimistic ...

The impact of climate and flooding on tree ring growth of Fraxinus pennsylvanica in north-central Texas.

The impact of climate and flooding on tree ring growth of Fraxinus pennsylvanica in north-central Texas.

Date: December 2009
Creator: Komperod, Mari
Description: Tree cores of Fraxinus pennsylvanica were used in a dendrochronological analysis investigating the species' responses to climate and flooding. The objective was to develop a model that incorporates the effects of precipitation, temperature, and flooding on radial growth in this species in north-central Texas. The trees exhibited strong climatic signals. The study clearly shows that all three factors have significant impacts on tree ring growth both prior to and during growth; however, the nature and extent of these impacts are highly dependent on what time of year they occur. The large temporal variations in growth responses emphasize the importance of considering the timing of environmental events when studying tree growth responses.

Impact of Forecasting Method Selection and Information Sharing on Supply Chain Performance.

Impact of Forecasting Method Selection and Information Sharing on Supply Chain Performance.

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Pan, Youqin
Description: Effective supply chain management gains much attention from industry and academia because it helps firms across a supply chain to reduce cost and improve customer service level efficiently. Focusing on one of the key challenges of the supply chains, namely, demand uncertainty, this dissertation extends the work of Zhao, Xie, and Leung so as to examine the effects of forecasting method selection coupled with information sharing on supply chain performance in a dynamic business environment. The results of this study showed that under various scenarios, advanced forecasting methods such as neural network and GARCH models play a more significant role when capacity tightness increases and is more important to the retailers than to the supplier under certain circumstances in terms of supply chain costs. Thus, advanced forecasting models should be promoted in supply chain management. However, this study also demonstrated that forecasting methods not capable of modeling features of certain demand patterns significantly impact a supply chain's performance. That is, a forecasting method misspecified for characteristics of the demand pattern usually results in higher supply chain costs. Thus, in practice, supply chain managers should be cognizant of the cost impact of selecting commonly used traditional forecasting methods, such as moving ...

The Impact of Legal Sanctions on Recidivism Rates among Male Perpetrators of Domestic Violence

The Impact of Legal Sanctions on Recidivism Rates among Male Perpetrators of Domestic Violence

Date: December 2009
Creator: Cosimo, S. Deborah
Description: Using a Cox proportional hazards regression model, this dissertation explores three factors currently not addressed in the literature on men who batter women and who are court ordered to participate in a battering intervention program. These factors are the cumulative effects of civil and criminal legal sanctions (dose-response of sanctions) for domestic violence related offenses on recidivism, reduced opportunities to recidivate, and whether the number of legal sanctions imposed has an effect on how long a man maintains his non-recidivism status. Because one domestic violence case may involve multiple sanctions, this study uses the Legal Sanction Dose-Response Index to gauge the cumulative impact of civil and criminal sanctions upon recidivism of domestic violence. The Cox proportional hazards model indicates that the risk of recidivism is 45% lower for men who experienced two legal sanctions (typically arrest and probation) in response to the index case, relative to men who experienced one legal sanction (typically civil protective order). In other words, those with two legal sanctions are able to maintain their non-recidivism status longer relative to those with one sanction. Men with prior criminal court involvement for domestic violence related offenses are more likely to recidivate. Additionally, rather than incarceration reducing opportunities ...

The Impact of Surveillance Technology on the Behaviors of Municipal Police Departments

The Impact of Surveillance Technology on the Behaviors of Municipal Police Departments

Date: December 2009
Creator: Ulkemen, Sinan
Description: Citizen complaints about inappropriate use of force indicate negative police-public relations, unresponsive police services, and the unresponsiveness of police management to citizens' concerns. However, the effective delivery of key policing services depends on the performance of individual police officers. Surveillance technology can monitor and control the behavior of officers, ensuring that police officers provide high quality policing services that meet the needs of citizens. Examples of surveillance technology such as in-car cameras and CCTV can be used as an administrative tool to respond to citizen complaints by police chief executives. This research examines the effect of surveillance technology on the behavior of municipal police departments that is operationalized as the number of citizen complaints that were filed against municipal police departments. This research also examines the impact of surveillance technology on dismissed and sustained complaints by using 511 large municipal police departments in the U.S. from Law Enforcement Management and Administrative Statistics (LEMAS) 2003 dataset. Three different models are developed to evaluate the impact of in-car cameras and CCTV on the citizen complaints and their dispositions. Two ordinary least square regression (OLS) models and a Heckman selection model are used to analyze the data. The Heckman selection model is utilized ...

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens

In vitro Cultures of Morus alba for Enhancing Production of Phytoestrogens

Date: December 2009
Creator: Bakshi, Vibhu
Description: Plant estrogens have long been associated with health benefits. The potential of tissue culture techniques for the production of several secondary metabolites has been known for many years. Tissue cultures stimulate the production or induce the biosynthesis of novel compounds not found in the mature plant. Tissue culture of Morus alba, family Moraceae, is known to contain phytoestrogens, was established on plant-hormone supplemented Murashige and Skoog (MS) medium. Petiole and the stem tissue from mature trees were the best explants for initiation and proliferation of calli. The best callus proliferation was obtained on MS medium containing 1-napthalene acetic acid (1mg/ml) and benzylaminopurine (0.5mg/ml) for M. alba. Comparison of phytoestrogens of Moraceae species from in vivo and in vitro tissue isolation were carried out. The estrogenic activities of callus extracts were assayed in an estrogen-responsive yeast system expressing the human estrogen receptor alpha. Male callus extracts had higher estrogenic activity than male and female extracts from in vivo and in vitro tissues. Isolation and characterization of phytoestrogens from above tissues were carried out using solid phase extraction, high perfomance liquid chromatography and mass spectrometry techniques. Biochanin A, an isoflavonoid, was isolated as one of the compounds in male callus extracts. Biochanin ...

Inferring Social and Internal Context Using a Mobile Phone

Inferring Social and Internal Context Using a Mobile Phone

Date: December 2009
Creator: Phithakkitnukoon, Santi
Description: This dissertation is composed of research studies that contribute to three research areas including social context-aware computing, internal context-aware computing, and human behavioral data mining. In social context-aware computing, four studies are conducted. First, mobile phone user calling behavioral patterns are characterized in forms of randomness level where relationships among them are then identified. Next, a study is conducted to investigate the relationship between the calling behavior and organizational groups. Third, a method is presented to quantitatively define mobile social closeness and social groups, which are then used to identify social group sizes and scaling ratio. Last, based on the mobile social grouping framework, the significant role of social ties in communication patterns is revealed. In internal context-aware computing, two studies are conducted where the notions of internal context are intention and situation. For intentional context, the goal is to sense the intention of the user in placing calls. A model is thus presented for predicting future calls envisaged as a call predicted list (CPL), which makes use of call history to build a probabilistic model of calling behavior. As an incoming call predictor, CPL is a list of numbers/contacts that are the most likely to be the callers within ...

The Influence of Giovanni Bottesini (1821-1889) on Pedro Valls (1869-1935): An Analysis of Homenaje à Bottesini (1906) by Pedro Valls

The Influence of Giovanni Bottesini (1821-1889) on Pedro Valls (1869-1935): An Analysis of Homenaje à Bottesini (1906) by Pedro Valls

Date: December 2009
Creator: Amorim, George
Description: This document traces a link between Pedro Valls and Giovanni Bottesini by identifying traits of Homenaje à Bottesini that resemble techniques and musical characteristics of Bottesini's music, through the comparison of Valls' Homenaje à Bottesini to Bottesini's Fantasia sur La Sonnambula, focusing on the works formal, musical and idiomatic characteristics. This is supported by documented evidence of Bottesini's presence in Spain during Valls's lifetime and Pedro Valls contact with the Italian master of the double bass school of playing and teaching method. This study also proposes adjustments in the notation of Homenaje à Bottesini to more modern and player-friendly score indications, which will help its inclusion into the active double bass repertoire. This document examines performance practice(s) of the work and what advantages or disadvantages these practices have in playing the work, and to ultimately offer a clear pathway, a road map, to performers interested in delving into Pedro Valls's work, with a better idea of what Valls's style consists of and what approach to take when performing his works.

Interactions of equivalence and other behavioral relations: Simple successive discrimination training.

Interactions of equivalence and other behavioral relations: Simple successive discrimination training.

Access: Use of this item is restricted to the UNT Community.
Date: December 2009
Creator: Brackney, Ryan
Description: The experimenter asked if documented equivalence class membership would influence the development of shared discriminative stimulus function established through simple successive discrimination training. In Experiment 1, equivalence classes were established with two sets of 9 stimuli. Common stimulus functions were then trained within or across the equivalence classes. Greater acquisition rates of the simple discriminations with stimuli drawn from within the equivalence classes were observed. In Experiment 2, a third stimulus set was added with which no equivalence relations were explicitly trained. The findings of Experiment 1 were replicated, but the Set 3 results were inconsistent across subjects. The outcomes of the two experiments demonstrate that equivalence classes have an effect on other behavioral relations which requires further investigation.
