Trust in automatic controllers may have an impact on awareness of system limitations and ultimately use of these systems. The purpose of this research is to determine the effects and likelihood of too much trust (overtrust) in drivers that use adaptive cruise control (ACC), a type of automatic controller that maintains vehicle speed and headway time. To add to the existing literature, this study aimed to define a significant relationship among trust, use, and awareness of ACC limitations. A post mailed or electronic-based survey was distributed to potential ACC users with 118 responses used for the main analysis. The survey responses provided demographic information, illustrated levels of trust, awareness of ACC limitations, and system use. A hierarchical cluster analysis of the data related to trust in ACC produced four clusters: overtrust, cautious, neutral, and distrust. Binary and multinomial logistic regression models then predicted the likelihood for overtrust (cluster membership). Participants in the overtrust cluster displayed the lowest level of awareness regarding ACC limitations and the highest levels of misuse. Users were more likely to overtrust ACC if they were male, misused the system, lacked limitation awareness, and indicated a willingness to opt for ACC in their next vehicle. Overtrust in ACC was shown to lead to misuse and cloud awareness of the systems' limitations. Trust seemed to be formed in the initial interactions with ACC therefore a priori trust levels of potential users should be sought before appropriate guidance is given or demonstrated through test use.

Background: Measuring the acquisition of self-management skills are part of evidence based health care transition practice. Youth with Spina Bifida have significant demands for self-management and high self-care burden. We developed an 11 item Spina-Bifida -TRAQ to assess self-management skills specific for Spina Bifida including urine, stool continence management, and skin and shunt maintenance. A detailed description of the SB-TRAQ, its reliability and criterion validity are presented elsewhere. Objective: To examine the predictive validity of the Spina Bifida-TRAQ among youth with Spina Bifida. Design/Methods: Participants include 90 youth with Spina Bifida who attend a clinic participating in the National Spina Bifida Patient Registry (NSBPR) (see Table1 for demographics). Youth completed the newly developed 11-item SB-TRAQ. De-identified NSBPR data from the electronic medical record (EMR) was linked with participants’ responses from the SBTRAQ. Two separate regressions were conducted using: age, sex, race, ethnicity, insurance, lesion level, lifetime # of shunt revisions, and SB-TRAQ to predict urinary incontinence (UI) episodes/month, and stool incontinence (SI) episodes/month. Results: Two separate multiple linear regressions were calculated to predict frequency (times per month) of UI and SI based on age, sex, race, ethnicity, insurance, having an IEP, spinal cord lesion level, lifetime number of shunt revisions, and SB-TRAQ. For UI, a significant regression equation was found (F(9,77) = 2.44, p<.001), with an R2 of .22. SB-TRAQ and IEP were significant predictors of UI; youths’ UI decreased 1.15 days/month for each point increase in SB-TRAQ; youth with an IEP had .83 more episodes of UI/month than did youth without an IEP. The model for SI had a significant regression equation (F(9,75) = 3.18, p<.001), with an R2 of .28. SB-TRAQ and lesion level were significant predictors of SI; youths SI decreased .58 days for each point increase in SB-TRAQ; each lower lesion levels (.13/level) had fewer SI episodes/month than did those with higher lesion levels. Conclusion(s):

Background: Measuring the acquisition of self-management and health care utilization skills are part of evidence based transition practice. The Transition Readiness Assessment Questionnaire (TRAQ) is a validated 20-question and 5-factor instrument with a 5-point Likert response set using a Stages of Change Framework. Objective: To improve the performance of the TRAQ and allow more precise measurement across the full range of transition readiness skills (from precontemplation to initiation to mastery). Design/Methods: On data from 506 previously completed TRAQs collected from several clinical practices we used MPlus v.7.4 to apply a graded response model (GRM), examining item discrimination and difficulty. New questions were written and added across all domains to increase the difficulty and discrimination of the overall scale. To evaluate the performance of new items and the resulting factor structure of the revised scale we fielded a new version of the TRAQ (with a total of 30 items) using an online anonymous survey of first year college students (in process). Results: We eliminated the five least discriminating TRAQ items with minimal impact to the conditional test information. After item elimination (k = 15) the factor structure of the instrument was maintained with good quality, ?2 (86) = 365.447, CFI = 0.977, RMSEA = 0.079, WRMR = 1.017. We also found that a majority of items could reliably discriminate only across lower levels of transition readiness (precontemplation to initiation) but could not discriminate at higher levels of transition readiness (action and mastery). Therefore we wrote 15 additional items intended to have higher difficulty. On the new 30 item TRAQ, confirmatory factor analysis, internal reliability and IRT results will be reported from a large sample of college students Conclusion(s): Using IRT and factor analyses we eliminated 5 of 20 TRAQ items that were poorly discriminating. We found that many of the items in the TRAQ could discriminate among those in the early stages of transition readiness, but could not discriminate among those in later stages of transition readiness. To have a more robust measure of transition readiness we added more difficult items and are evaluating the scale’s psychometric properties.

Background: Measuring the acquisition of self-management and health care utilization skills are part of evidence based health care transition practice. Youth with Spina Bifida (SB) have significant demands for self-management and high self-care burden. To complement HCT skills assessed in the TRAQ, we developed an 11 item SB-TRAQ to assess self-management skills specific to Spina Bifida. Similar to the TRAQ, the SB-TRAQ uses a 5-point Likert responses using Stages of Change. Objective: To develop and assess the reliability and validity of a questionnaire to measure independence and skill acquisition for youth with SB. Design/Methods: Working with a multidisciplinary team of experts in the care of youth with SB we developed a twelve item questionnaire specific to the main facets of SB self-care and -management including urine and stool continence, prevention of skin breakdown and awareness of signs of shunt malfunction. The items were reviewed and revised through several iterations by healthcare providers and patients. The SB-TRAQ was fielded in an SB Specialty Clinic participating in the National Spina Bifida Patient Registry (NSBPR). Ninety youth with SB completed the 20-item TRAQ and the 12-item SB-TRAQ. Item response means, and distributions were assessed. A principal component analysis (PCA) was conducted with oblique rotation (promax). We also assessed criterion validity by examining the correlation of the SB-TRAQ supplement with the TRAQ and age. Results: Sample characteristics and scale information for the TRAQ and SB-TRAQ supplements are displayed in Table 1, including a Cronbach alpha of 0.9 for the SB-TRAQ. The item characteristics are provided in Table 2. Results of the factor analysis show eleven items loaded onto one factor, with almost all items loadings > 0.7 . One item did not load, resulting in an 11 item solution. The primary factor explained 62% of the variance. Intraclass correlations of the SB-TRAQ supplement with the TRAQ overall scale and subscales demonstrated good criterion validity (TRAQ overall ICC = .74; ICCs varied among the subscales and the SB-TRAQ). Additionally, the SB-TRAQ, as hypothesized, was significantly and positively correlated with age (Pearson correlation .29, p<.01). Conclusion(s): Results of our analyses demonstrate that the SB-TRAQ had good internal reliability and excellent criterion validity as demonstrated by strong correlation with age and the validated TRAQ. The SB-TRAQ can be a useful tool to help youth with SB achieve independence and self-management.

Due to the growing recognition of the social and ecological consequences of the global decline in pollinator species, the need for more effective policies for the conservation of pollinator habitat is now more than ever. These trends call for research that provides a deeper understanding of farmers' decision-making processes. In this regard, this study tested a modified version of the Theory of Planned Behavior as a conceptual model for explaining farmers' perceptions and behavior regarding the adoption of pollinator conservation programs and practices. Specifically, the study tested how farmers' perceived behavioral control, attitudes, subjective norms, concern about herbicide resistance issues, and sociodemographic variables influence their intentions and actual adoption of pollinator conservation programs and practices. Quantitative survey data were gathered from 41 principal farm operators in the state of Illinois through the administration of a web-based survey. The resulting data were first explored using descriptive statistics and correlation analysis, following which multiple regression analysis was used to test four hypotheses on the predictors of farmers' intentions to adopt, as well as their adoption of pollinator conservation practices and programs. The results from the regression analysis showed that farmers' attitudes and their subjective norms had statistically significant positive effects on their adoption of pollinator conservation practices on their farms, as well as their intentions to adopt those practices in the near future. Perceived behavioral control also had a statistically significant positive effect on farmers' adoption of federal pollinator conservation programs, as well as their intentions to enroll in these programs in the future. Overall, these findings call for comprehensive pollinator conservation policies that facilitate the provision of information and incentives for farmers to voluntarily adopt pollinator conservation practices on their farms, as well as the provision of appropriate resources and opportunities for farmers to enroll in pollinator conservation programs over which they have minimal control.

Many children with emotional and/or behavioral disorders also present with speech and language disorders (Baker & Cantwell, 1982; Prizant et al., 1990). Children with attention deficits, in particular, have shown a much higher incidence of speech and language disorders than does the general population (Camarata et al., 1988; Cantwell & Baker, 1987) . Traditionally, school speech-language pathologists have been responsible for conducting mass screenings to determine which children should be further evaluated for speech and language disorders. An increasing number of school districts are relying on teacher referrals to determine which children require speech-language evaluations. It was hypothesized that if teachers were able to identify children with attention deficits, these children may be appropriate for referral to speech-language pathologists for speech and language evaluation. The purpose of this study was to determine the effectiveness of the School Situations Questionnaire-Revised {SSQ-R) {Barkley, 1991) in identifying children in the second grade, aged 7:0 to 8:11, who are speech and/or language disordered. This study sought to answer the following primary question: is there an association between the diagnosis of speech and/or language disorders {SLD), and detection by the SSQ-R as at risk for attention and behavior disorders {ABD)? The sample population consisted of 91 students from six second-grade classrooms who met the selection criteria. The SSQ-R, a rating scale designed for teachers to rate behavior related to attention and concentration, was used by classroom teachers to evaluate the subjects to determine if they were at risk for attention and behavior disorders. These results were tabulated along with the number of children diagnosed with speech and/or language disorders in this population. Chi Square analysis showed no significant association for the two measures. It was found that of the 11 SLO subjects, 3 of them, or 27%, were also ABO. Only 3 of the 17 ABO subjects (18%) were also SLO. The 18% of SLO subjects in the ABO population and the 27% of ABO subjects in the SLO group represent a higher percentage of ABD and SLO than is expected in the general population. The higher than average incidence of SLO in the ABO population warrants an awareness of this relationship and the realization that this will impact service delivery. The results of this study indicate that the SSQ-R is not an appropriate measure for teachers to use in determining which children in their classroom would benefit from an assessment for speech and/or language disorders. The high number (82%) of children identified by the SSQ-R as ABD who were not SLD would identify many children who did not require speech and language evaluation. Conversely, the high number (73%) of children not identified as ABD who were SLD by the SSQ-R would neglect many children who require speech/language intervention. The results of this study are not to discount previous research that has suggested an association between attention deficit hyperactivity disorder, and speech and language disorders. It is likely that an association exists, but the present study was not able to demonstrate a significant correlation.

The diploma thesis is focusing on the contemporary movement called "early start" in the education of the English language. Almost all nursery schools offer today the extra lessons for children. The diploma thesis presents not only the actual negative and positive arguments for the early start lessons but also the theoretical resource for the development of language and communicative competences of children. Also the topic of learning a foreign language and its influences as well as the politics of educating foreign languages in the world and in the Czech Republic are included. The practical part of the thesis will try to enrich the debate about the early start by individual experience and findings of six children who were interviewed. Their information was completed by the acquaintances of their parents that filled the questionnaire.
