Traffic signs, which transportation agencies must inventory and manage, are one of the most important roadway assets because they are used to ensure roadway safety and provide important travel guidance/information. Traffic sign inventory and condition assessment are two important components that are essential for establishing a cost-effective and sustainable traffic sign management system. Traditionally, state departments of transportation (DOTs) have conducted traffic sign inventory and condition assessment manually, a process that is labor-intensive, time-consuming, and sometimes hazardous to field engineers in the roadway environment. Methods have been developed to automate sign inventory and condition assessment using video log images in previous studies. However, the performance of these methods still needs to be improved. Based on the need to inventory signs and manage them more effectively, this study has two focuses. The first focus is to develop an enhanced traffic sign detection methodology to improve the productivity of an image-based sign inventory for state DOTs. The proposed methodology includes two enhanced algorithms: a) a lighting dependent statistical color model (LD-SCM)-based color segmentation algorithm that is robust to different image lighting conditions, especially adverse lighting and b) an ordinary/partial differential equation (ODE/PDE)-based shape detection algorithm that is immune to discontinuous sign boundaries in a cluttered background. The second focus of the study is to explore a new traffic sign retroreflectivity condition assessment methodology to develop a mobile method that uses emerging computer vision and mobile light detection and ranging (LiDAR) technologies to assess traffic sign retroreflectivity conditions. The proposed methodology includes a) an image-LiDAR registration method employing camera calibration and point co-planarity to register the 3D LiDAR point cloud with 2D video log images, b) a theoretical-empirical normalization scheme to adjust the magnitude of the LiDAR retro-intensity values with respect to LiDAR beam distance and incidence angle based on the radiometric responses, and c) a population-based retroreflectivity condition assessment method to evaluate the adequacy of a traffic sign retroreflectivity condition based on the correlation between the normalized LiDAR retro-intensity and the retroreflectivity values. For the proposed traffic sign detection methodology, comprehensive tests using representative datasets (e.g. with different road functions, data collection sources, and data qualities) were conducted to validate the performance of the two enhanced algorithms and the complete methodology. For the proposed retroreflectivity condition assessment methodology, the fundamental behavior of LiDAR retro-intensity was comprehensively tested and simulated under a controlled lab and roadway environment to quantify the impact of beam distance and incidence angle. A preliminary test on Type 1 engineer grade stop signs was conducted in the field to validate the performance of the proposed sign retroreflectivity condition assessment method. The results from both of the proposed methodologies are promising.

SAMMANFATTNING Sjuksköterskan tillämpar omvårdnadsprocessen genom att observera, värdera, prioritera, dokumentera och vid behov åtgärda och hantera förändringar i allmäntillståndet, samt motverka komplikationer i samband med sjukdom, vård och behandling. Andningsfrekvens (AF) är den vitalparameter som först förändras och signalerar en förändring i allmäntillståndet. Vid de flesta hjärtstopp på sjukhus finns tecken till försämring hos patienten redan några timmar eller upp till ett dygn före.  Syftet var att undersöka sjuksköterskans inställning och följsamhet till att mäta och bedöma AF hos akuta sjuka patienter, för att tidigt upptäcka en försämring i patientens hälsotillstånd. Genom en litteraturstudie framkom fyra teman. Rutiners betydelse, sjuksköterskans inställning till AF och varför den inte mättes, värdet av förändringsarbete samt möjliga arbetssätt för att undvika vårdskador. Rutiner för mätning av AF, olika poängsystem och mätmallar för bedömning av vitalparametrar, påverkade antalet mätningar och registreringar av AF. Den enskilda sjuksköterskans inställning inverkade på mätningen och bedömningen av AF. Flera anledningar till varför AF inte mättes fanns. Studier visade att förändringsarbete och implementering av nya arbetssätt var ett komplext område, insatser krävdes inom flera områden på olika nivåer. Vårdskador och plötslig oväntad död minskade när nya rutiner och arbetssätt kombinerades med utbildning, uppföljning och återkoppling till personalen. AF är en viktig vitalparameter. Används inte den kunskapen för att hitta patienter på väg att försämras, riskerar patienterna att drabbas av vårdskador. Ett utbildningsbehov finns, den senaste forskningen har påvisat att rätt genomförd implementering av övervakningsrutiner och förändrat arbetssätt kan ge ett bra utfall i minskat antal vårdskador och oförutsedd död. / ABSTRACT The nurse applies the nursing process by observing, evaluating, prioritising, documenting and when necessary manage changes in the condition of the patient, and to prevent complications associated with disease, care and treatment. Respiratory Rate (RR) is the vital sign that first changes and signals changes in a patient’s condition. In most cardiac arrests there are signs of deterioration of the patient a few hours up to a day before the event.    The aim of this study was to investigate the nurse´s attitude and adherence to measure and assess RR in acutely ill patients, for an early detection of deterioration in the patient's state of health. Through a literature study four themes were emerged. The importance of guidelines, the nurses' attitude and why the RR was not measured, the value of change of management and possible ways to avoid injuries. Guidelines for the measurement of RR, different scoring systems and observations charts for the assessment of vital signs all affected the measuring and scorings of RR. The individual nurse's attitude affected the measurement and assessment of RR. Several reasons why RR was not measured were found. The studies showed that the process of change and implementation of new ways of working is a complex, and efforts were needed in several areas and at different levels. Care injuries and sudden unexpected deaths decreased when new routines and working procedures were combined with training, monitoring and feedback to the staff.   Research shows that RR is an important vital sign. If this knowledge is not used to find patients about to deteriorate, these patients risk suffering from permanent health effects. There is a need for significant training in this area and recent research has shown that a correct implementation of the procedures provide a good outcome in a decreased number of medical injuries and unexpected death

Abstract Verbal behavior encompasses a wide range of aspects in our everyday lives and in the activities of a society. Many verbal behavior interventions often include programs to teach answering questions, these responses are referred to as intraverbals. Previous research has demonstrated a higher rate of acquisition of verbal targets such as mands and tacts for children with a limited verbal repertoire when a presentation of both sign and vocal prompts occur simultaneously (Total Communication), in comparison to sign-alone or vocal-alone trainings. However, an important variable not often examined in the literature is the comparison of Total Communication (TC) and Prompt Delay (PD) to further evaluate which leads to higher rates of acquisition. The current study extends previous research by evaluating the relative effectiveness of TC and PD in teaching intraverbal skills to three children who have been diagnosed with autism. During the TC condition the participants were required to emit a vocal and sign response simultaneously during training. During the PD condition, participants were required to emit only a vocal response during training. The results suggest that there was no clinically relevant difference between the two conditions in the acquisition of intraverbals for these participants.

Hearing children whose parents are deaf live between two linguistic and cultural communities. As in other bilingual families, parents and children make choices in their home language use that influence the children’s competence in the minority language--ASL--and language maintenance across generations. This dissertation presents 13ethnographic interviews of hearing adults with deaf parents and case studies of three families, two with two deaf parents and three hearing sons (ages 3-16) and one with a deaf mother and her hearing 2-year-old daughter. Analysis of the adult interviews reveals that--despite variation in community affiliation and sign language ability and practice--these adult children of deaf parents share a functional language ideology in which family communication potentially involves effort; putting in such effort is appropriate only to the degree that it overcomes communication barriers. Analysis of the family members’ code choices in two hours of videotaped naturalistic interaction at home was supplemented by observation and interviews. The families’ children behaved in a manner consistent with the interviewed adults’ functional language ideology, restricting their signing to times of communicative necessity. Using an analytical framework based on Bell’s (1984; 2000) theory of audience design, I coded every communicative turn for the role of each family member (speaker/signer, addressee, participant, bystander) and for the communication medium (sign, gesture, mouthing, speech, etc.). The children consistently adjusted their code choices to their addressees, occasionally signing to their siblings, but always for an obvious purpose, e.g., keeping a secret. Only the oldest brother in each family showed any tendency to accompany speech to a sibling with signing when a deaf parent was an unaddressed participant. Between these fluent bilingual children, signing was available as a communicative resource but never the default option. Given that the hearing children even in these culturally Deaf families tended toward speech whenever communicatively possible, it is no surprise that children whose deaf parents have strong skills in spoken English might grow up with limited signing skills--as did some of the interviewed adults--and therefore restricted access to membership in the Deaf community. / text
