This quantitative study derived from an on-going federal experimental research project targeting Spanish-speaking English language learners (ELLs) receiving services in four program models: control/experimental transitional bilingual education (TBE) and control/experimental structured English immersion (SEI). The purpose of my study was (a) to capture the growth trajectory and rate of oral English acquisition, (b) to investigate the role of oral English development in acquiring English reading skills, and (c) to compare program models in order to identify practices that promote ELLs’ English oral and reading competency at the early elementary level. Structural equation modeling was utilized. Participants consisted of 534 Spanish-speaking ELLs who started at kindergarten and continued through first grade in their respective models. Striking similarities were found among the four instructional models that English oral proficiency improved significantly (p < .05) in a linear fashion over two years. However, the magnitude differed in that the experimental TBE demonstrated a steeper growth (p < .025) than that of the control group that started at the same level. Even though experimental SEI group started at a much lower level in oral English, they progressed at a rate significantly higher (p < .05) than that of the control group. In relation to English reading comprehension, for experimental SEI groups, the initial level of English oral proficiency is of great concern in reading achievement (p < .05). For both TBE groups, effective intervention is desired because the growth of English oral proficiency strongly impacts reading achievement (p < .05), and, in addition, initial level strongly predicts reading comprehension. The intervention was successfully implemented so that students advanced to a substantial amount in academic English oray. It is also evident that first language (L1) instruction did not impede the learning of a second language. On the contrary, for those students receiving a larger proportion of L1 instruction, alterations in program models are needed to nurture English oracy at a faster rate of growth, which in turn facilitates English literacy acquisition. Findings also indicate that without effective English intervention, students placed in control TBE classrooms remain below all the students in oral English proficiency.

As virtual channels on the internet grow full-blown, two major chain department store corporations in Taiwan entered internet markets one after another in 2007. Since the department store is a typical service industry highly based on interactions, the salesclerk has been a major mediator for serving customers and therefore face-to-face interaction between consumers and salesclerks is especially important. With the coming of brand-new self-service system combined with technology, consumers are able to take advantage of the technology to serve themselves. The relationship between corporations and consumers is hence transformed with a delivery system of ¡§low contact but high technology.¡¨ Researchers of previous studies mainly focus on interpersonal-based service encounter for investigation of relationship marketing and customer loyalty and researches about technology-based self-service and interaction with consumers are rarely seen. This research takes department store customers as subjects of investigation and adopts their viewpoints from questionnaire, aiming to probe into the influence of the department store¡¦s introduction of self-service technology on the effect of relationship marketing for better understanding of the relationship between the effect and customers loyalty. The study will take questionnaire survey of internet, and put the questionnaire on the Telecommunication Laboratories (TL) website to gather data via the customer¡¦s e-mail in cooperation with the Web-based Newspaper for the credit card users of the department store of the department store. The questionnaire will put for one month from February 1 to February 28, 2008 to gather enough data for analysis. A total of 1412 copies of questionnaire are issued, retrieving 396 copies, with 1016 copies of effective questionnaire. Structural Equation Modeling is used in this research. The followings are four points of conclusion: (1) the quality of web-based self service has significantly positive influence on result indicators of relational benefits by means of customer relational benefits; (2) the quality of web-based self service, except for delivery service speed, has significantly positive influence on customer relational benefits; (3) customer relational benefits have significantly positive influence on result indicators of relational benefits; (4) customer relational benefits bring significant effect as a mediator between web-based self service and result indicators of relational benefits. Therefore, we suggest that the department store managers shall create more elements of relationship benefit so that the customers all feel highly of the relationship benefit in the hope to enhance the customer's satisfaction and loyalty on the enterprise.

Many environmental behavior models have been proposed to predict or explain environmental behavior in the past two decades. Due to limitations in practice, these models were mostly tested on a basis of self-reported measures of environmental behavior. How would these models perform if an observed measure of environmental behavior was used? What are the differences between the results of testing a model with a self-reported environmental behavior (SB) measure and the same model with an other-reported environmental behavior (OB) measure? And, what do these differences imply? A major model, Ajzen¡¦s (1985) theory of planned behavior (TPB), was tested with SB and OB measures respectively with structural equation modeling (SEM) analysis. Data were collected through questionnaires and participant observation in which students living in dormitories in a university were trained to observe their 172 roommates¡¦ five environmental behaviors. The other-reports of these roommates¡¦ environmental behavior made by the observers were based on their observation as well as experiences in living with and understanding of their roommates. Results showed that there existed significant frequency gaps between behavioral intention (BI) and SB and between SB and OB. The difference between SB and OB frequency was about 1.25 points on a 7-point scale. The BI-SB correlation (.87) was much larger than BI-OB correlation (.31) implying that SB was better predicted than OB was by BI. It was found that the subjects¡¦ SB tended to be conservative compared with BI and that OB was provided even more conservatively by the observers. BI could be the common cause of both SB and OB or SB could intervene in the relationship between BI and OB. A few significant differences were found in the results of testing the TPB model with SB and OB. The preference for the behavior might have played an essential role in predicting one¡¦s SB. The model had a very large proportion of variance explained (.814) because of the strong connection between BI and SB. It also seemed to have a better model fit when SB was used while the model¡¦s capability in predicting behavior was greatly reduced due to the large disparity between BI and OB when OB was used. Finally, it seemed that social desirability was a not cause of the SB-OB gap.

Nowadays experience marketing is the most common strategy to promote. Cultural- based activities in Kaohsiung is one of the examples to use such strategy. Culture is far more powerful than economy and politics. The influence by art and culture activities is direct, indirect and derivative on regional economy. Promoting art and culture activities as well as tourism industries significantly enhances conglomerate economy strength in the city. In terms of criticizing culture, the study concerns what aesthetic type created by urban experiential marketing strategy as well as what internet communications influence on cultural marketing. The study theory is based on B. Joseph Pine¢º& James H. Gilmore¡¦s experiential marketing aesthetics in 1998 and Schmitt¡¦s experience marketing theory in 1999, and thus explores three dimensions as experiential marketing strategy, aesthetics culture index and communication results. The survey research was performed by a questionnaire through convenient sampling method. A total of 280 questionnaires were administered, and 263 questionnaires were retrieved. AMOS Statistical Software was used to apply data analysis of the correlation among variables by using Structure Equation Modeling (SEM). The research results showed that: (1) experiential marketing strategy has positive effect on enhancing aesthetics culture; (2) there is no mediating effect about computer-mediated communication (CMC) between experiential marketing strategy and enhancing aesthetics culture of urban culture; (3) the cultural activities of experiential marketing strategy are prone to the entertainment. In addition to the entertainment, the long-term strategy of the government shall emphasize both on artistic and educative function when promoting the experiential marketing on urban culture. On the aspect of information context, both richness and interactivity of computer-mediated communication media content shall be enhanced. From the perspective of esthetical form of experiential marketing, we expect the findings of this study are helpful to consider the cultural information into the field of communication research in future planning for the urban cultural marketing to advance a city's global competitiveness.

Authentic leadership is a new concept that is gaining both popularity and notoriety in the leadership literature. It is argued as a positive form of leadership that goes beyond traditional leadership styles in order to influence followers through genuine, ethical behavior. However, as a concept in its infancy, authentic leadership has yet to receive much empirical attention, and many researchers are skeptical of its value in what is seen as a saturated domain of leadership styles. This study offers a comprehensive approach to addressing this need. A new measure for authentic leadership was developed and validated through pilot testing. Through additional analyses using this new measure, it was discovered that authentic and transformational leadership were not empirically distinct. However, by combining these two measures into an authentic-transformational leadership construct, it was still possible to examine the effect of greater amounts of authenticity in the leadership role. It was found that authentic-transformational leadership was directly related to a number of employee attitudes, and these, in turn, were related to positive employee behaviors. Results of this study are discussed both in terms of future research in the area of authentic-transformational leadership as well as its impact on organizational effectiveness.

This study examined the interrelationships between adolescent weight and several other variables thought to impact weight and obesity: physical activity, depressive symptoms, binge-eating symptoms, dieting, socio-economic status, special education status, gender, and ethnicity. The sample consisted of 251 high school students in rural Florida who completed measures of depression, binge-eating, dieting, and physical activity. Measurement instruments included the Reynolds Adolescent Depression Scale-2nd Edition (RADS-2), the bulimia scale of the Eating Disorder Inventory-2 (EDI-2), the dieting scale of the Dutch Eating Behavior Questionnaire (DEBQ), and a physical activity questionnaire derived from the Youth Risk Behavior Scale for Students (YRBSS). The study utilized path analysis, a group correlational design, to determine whether the proposed path model fit the data. Obese and non-obese students also were compared with regard to a) the levels of binge-eating symptoms, and b) the relationship between binge-eating and depression. Path analysis results were not statistically or clinically significant, suggesting a poor fit of the model to the data. Results indicated 19% of participants were obese and 20% were overweight. More than three times as many obese students than non-obese students reported experiencing a binge-eating experience at some time in the past. However, on the bulimia scale of the EDI-2, obese and non-obese participants did not differ statistically in their responses. Statistically but not clinically significant correlations were revealed between depression and binge-eating for the sample and also for non-obese students. For the sub-sample of 13 students who had both binged and dieted, 7 had binged first, 3 had dieted first, and 3 binged and dieted for the first time at the same age. Future research should continue to investigate the relationships of the variables related to obesity. Future directions might include a larger sampl e size and a modified sample selection process. Action research should continue in the areas of obesity prevention and intervention, and student services personnel should promote healthy lifestyle choices and a recognition of obesity as a socio-cultural problem.

The present research reports the first comprehensive map of brain networks underlying latent inhibition learning, the first application of structural equation modeling to cytochrome oxidase data, and the first effects of methylene blue, a known metabolic enhancer, on latent inhibition. In latent inhibition, repeated exposure to a stimulus results in a latent form of learning that inhibits subsequent associations with that stimulus. As neuronal energy demand to form learned associations changes, so does the induction of the respiratory enzyme cytochrome oxidase. Therefore, cytochrome oxidase can be used as an endpoint metabolic marker of the effects of experience on regional brain metabolic capacity. Quantitative cytochrome oxidase histochemistry was used to map brain regions in mice trained on a tone-footshock fear conditioning paradigm with either tone preexposure (latent inhibition), conditioning only (acquisition), conditioning followed by tone alone (extinction), or no handling or conditioning (naïve). In normal latent inhibition, the ventral cochlear nucleus, medial geniculate, CA1 hippocampus, and perirhinal cortex showed modified metabolic capacity due to latent inhibition. Structural equation modeling was used to determine the causal influences in an anatomical network of these regions and others thought to mediate latent inhibition, including the accumbens and entorhinal cortex. An uncoupling of ascending influences between auditory regions was observed in latent inhibition. There was also a reduced influence on the accumbens from the perirhinal cortex in both latent inhibition and extinction. These results suggest a specific network with a neural mechanism of latent inhibition that involves sensory gating, as evidenced by modifications in metabolic capacity, effective connectivity between auditory regions, and reduced hippocampal influence on the accumbens. The effects of methylene blue on disrupted latent inhibition were also investigated. Reduced tone-alone presentations disrupted the latent inhibition effect and led to an increase in freezing behavior. Repeated low-dose administration of methylene blue decreased freezing levels and facilitated the disrupted latent inhibition effect. Methylene blue administration also resulted in changes in metabolic capacity in limbic and cortical regions. A unique functional neural network was found in methylene blue-restored latent inhibition that emphasized sensory gating of auditory information, attention processing, and cortical inhibition of behavior. / text

Broadband light emitters operation, which covers multiple wavelengths of the electromagnetic spectrum, has been established as an indispensable element to the human kind, continuously advancing the living standard by serving as sources in important multi-disciplinary field applications such as biomedical imaging and sensing, general lighting and internet and mobile phone connectivity. In general, most commercial broadband light sources relies on complex systems for broadband light generation which are bulky, and energy hungry. Recent demonstration of ultra-broadband emission from semiconductor light sources in the form of superluminescent light emitting diodes (SLDs) has paved way in realization of broadband emitters on a completely novel platform, which offered compactness, cost effectiveness, and comparatively energy efficient, and are already serving as a key component in medical imaging systems. The low power-bandwidth product is inherent in SLDs operating in the amplified spontaneous emission regime. A quantum leap in the advancement of broadband emitters, in which high power and large bandwidth (in tens of nm) are in demand. Recently, the birth of a new class of broadband semiconductor laser diode (LDs) producing multiple wavelength light in stimulated emission regime was demonstrated. This very recent manifestation of a high power-bandwidth-product semiconductor broadband LDs relies on interband optical transitions via quantum confined dot/dash nanostructures and exploiting the natural inhomogeneity of the self-assembled growth technology. This concept is highly interesting and extending the broad spectrum of stimulated emission by novel device design forms the central focus of this dissertation. In this work, a simple rate equation numerical technique for modeling InAs/InP quantum dash laser incorporating the properties of inhomogeneous broadening effect on lasing spectra was developed and discussed, followed by a comprehensive experimental analysis of a novel epitaxial structure design. The layered structure is based on chirping the barrier layer thickness of the over grown quantum dash layer, in a multi-stack quantum dash/barrier active region, with the aim of inducing additional inhomogeneity. Based on material-structure and device characterization, enhanced lasing-emission bandwidth is achieved from the narrow (2 u m)ridge-waveguide LDs as a result of the formation of multiple ensembles of quantum dashes that are electronically different, in addition to improved device performance. Moreover, realization of SLDs from this device structure demonstrated extra-ordinary emission bandwidth covering the entire international telecommunication union (O- to U-) bands. This accomplishment is a collective emission from quantum wells and quantum dashes of the device active region. All these results lead to a step forward in the eventual realization of more than 150 nm lasing bandwidth from a single semiconductor laser diode.

Mean daily vegetable consumption is below the recommended 7-10 servings in the diet of adult Canadians. This thesis aimed to investigate the moderating role of perceived barriers on the relationship between motivation and (greater) vegetable consumption. 606 people from the Ontario Food panel participated in the online study. The results identified a positive moderating effect of perceived barriers on the relationship between autonomous motivation and vegetable consumption (p < .05) and negative approaching significance moderating effect of perceived barriers on controlled motivation and vegetable intake (p = 0.056). Also four motivational profiles of consumers were identified and described in terms of vegetable consumption, food related behaviors, stages of change and socio-demographic characteristics. These results extend the Self-Determination Theory with perceived barriers component and can inform intervention program development for social marketers and policy makers.

Interstitial Cystitis / Painful Bladder Syndrome (IC/PBS) is a persistent and refractory medical condition that is characterized by chronic pelvic pain along with abnormal urinary frequency and urgency. There is no widely accepted etiology or efficacious cure for IC/PBS, thus treatment often relies on pain and symptom management. IC/PBS is associated with strong functional disability but theoretical models of disability have yet to be tested with these patients. As well, psychosocial factors associated with various IC/PBS outcomes (i.e., depression, catastrophizing, social support) are also associated with disability in a variety of chronic painful medical conditions but remain untested in disability models for IC/PBS. Thus, this research evaluated psychosocial factors as potential mediators of disability within the Disablement Process Model. Female patients diagnosed with IC/PBS by a urologist in a tertiary care hospitals were recruited (n=196; females). In using structural equation modeling of a final IC/PBS disability model, negative affect and catastrophizing were found to be partial mediators on the relationship between impairments and functional disability and social support was not a significant mediator of disability. Negative affect and catastrophizing may be key psychosocial factors in IC/PBS disability. Research implications for the Disablement Process Model and potential clinical interventions are discussed in light of the current findings. / Thesis (Master, Psychology) -- Queen's University, 2011-08-29 14:18:29.478
