Transitions occur at many points in a child's educational journey. For children with disabilities, these changes in routine, service providers, and setting may be especially difficult and result in problem behavior. Special education teachers are expected to facilitate a smooth transition from one setting to another, teaching appropriate skills and addressing problem behavior as it arises. Board Certified Behavior Analysts (BCBAs), who have an expertise in problem behavior and skill generalization, are currently under-utilized in schools and could work collaboratively with special education teachers and other stakeholders to make it easier for students with disabilities experiencing a school transition. As only 12.16% of actively licensed BCBAs work in education, the literature on effective collaboration practices between BCBAs and special education teachers, particularly in transition, is scarce. We organized seven Multi Perspectival IPA focus groups, including a pilot study group, made up of 25 special education teachers and administrators who have worked with BCBAs. Results show that a duality exists among special educators in this work- special educators expressed both a genuine desire to work with BCBAs, as well as a desire to be acknowledged and respected for their own work and expertise with students, indicating a complexity in this collaborative relationship. Implications for practice, implications for research, and limitations are discussed.

In many parts of the country principal candidates are being licensed through alternative pathways. Some view this movement as a plausible solution to the shortage of principals and inadequacy of principal preparation programs (Hess, 2003; Southern Regional Education Board, 2006; Thomas B. Fordham Institute, 2003). Others are insulted and threatened by the prospect of a person from a non-traditional background leading a school (Fenwick & Pierce, 2001). The debate as to whether or not these candidates possess the prerequisite skills and knowledge to effectively lead a school continues. But, will superintendents, as gatekeepers to school districts, afford these individuals the opportunity to prove their worth as principals? In this study, superintendents’ attitudes toward alternative licensure of school principals; past behaviors related to hiring alternatively licensed school personnel; attitudes toward specific alternatively licensed personnel; perceptions of the conditions in their school districts; anticipated concerns about hiring alternatively licensed principals; and the presence or absence of a clearly articulated induction program for new principals are used as predictors of superintendents' willingness to recommend hiring alternatively licensed principals to their school boards. The composite model of attitude-behavior consistency and data from a qualitative study of 18 superintendents were the bases for the development of a theory. To test the theory, an on-line questionnaire, using Likert and Thurstone scaled items, was administered to 1200 randomly selected superintendents who were members of the American Association of School Administrators (AASA) in 2005. Multiple regression analysis was used for the analysis of the quantitative data. Five of the 19 predictor variables were significant predictors of superintendents’ willingness to recommend hiring alternatively licensed principals. The strongest relationship existed between superintendents’ willingness to recommend hiring alternatively licensed principals and their perceptions of the instructional leadership ability of alternatively licensed principals. Other significant predictors were superintendents’ past experiences hiring alternatively licensed principals, perceptions of the community acceptance of alternatively licensed principals, general attitude toward alternative licensure, and willingness to hire under the given definition. Superintendents displayed a low neutral (more unfavorable) score on the Thurstone scale, which means they view the employment of alternatively licensed principals slightly unfavorably. / Ph. D.

[pt] Os analisadores hematológicos são sistemas de medição que permitem identificar elementos sanguíneos, incluindo a contagem diferencial dos cinco tipos de leucócitos encontrados no sangue periférico: neutrófilos, linfócitos, monócitos, eosinófilos e basófilos. Devido à inexistência de materiais de referência certificados ou métodos de referência para a análise diferencial de leucócitos, tem sido habitual avaliar o desempenho de novos analisadores comparando-os com sistemas tradicionalmente disponíveis e bem consolidados. Em 2015, foi lançada uma nova tecnologia portátil e de baixo custo, o modelo DxH500 (Beckman Coulter), baseada na perda axial de luz usando LED azul como emissor, combinada à medição de impedância. O presente trabalho compara o desempenho do DxH500 com um modelo bastante utilizado desde seu lançamento em 2001 para exames laboratoriais em larga escala, o modelo LH750 (Beckman Coulter), baseado na combinação dos princípios de impedância, condutividade e dispersão de luz (VCS). No estudo foram examinadas 310 amostras pareadas. A análise comparativa entre os resultados fornecidos por cada dispositivo indicou uma boa correlação para a caracterização de neutrófilos, linfócitos, monócitos e eosinófilos. Apesar da reduzida correlação observada para a contagem de basófilos, esse resultado não apresenta relevância clínica já que os valores obtidos para as amostras avaliadas foram muito reduzidos, inferiores aos limites de referência. Embora a análise comparativa realizada tenha apontado para um desempenho equivalente utilizando-se tecnologias com princípios diversos, a adequada avaliação dos dispositivos de análise hematológica requer o desenvolvimento de materiais de referência certificados, uma demanda fundamental para a garantia da confiabilidade na quantificação diferencial de leucócitos. / [en] Hematology analyzers are measurement systems that allow the identification of blood elements, including differential counting of the five types of leukocytes found in peripheral blood: neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Because of the lack of certified reference materials or reference methods for differential leukocyte analysis, it has been customary to evaluate the performance of new analyzers by comparing them with traditionally available and well-established systems. In 2015, a new low-cost, portable technology was introduced, the Beckman Coulter DxH500 model, based on the axial loss of light using blue LED as a combined transmitter for impedance measurement. The present work compares the performance of the DxH500 with a widely used model since its launch in 2001 for large-scale laboratory tests, the Beckman Coulter model LH750, based on the combination of impedance, conductivity and scatter (VCS). In the study, we examined 310 paired samples. The comparative analysis between differential leukocyte evaluation results provided by each device indicated a good correlation for the characterization of neutrophils, lymphocytes, monocytes, and eosinophils. Despite the low correlation observed for basophil counts, this result is not clinically relevant since the values obtained for the evaluated samples were very low, lower than the reference limits. Although the comparative analysis carried out pointed to an equivalent performance using technologies with different principles, the adequate evaluation of hematological analysis devices requires the development of certified reference materials, fundamental demand for the reliability of the differential quantification of leukocytes.

The majority of individuals in nursing homes have cognitive-communication impairments which impact quality of care because direct care providers, certified nursing assistants, (CNAs) are unsure how to respond to resident’s communication behaviors. One intervention that facilitates staff-resident communication in nursing homes is communication plans; however, the research to date about communication plans has not specifically involved CNAs. The purpose of this study, using a grounded theory qualitative approach, was to describe development, implementation and evaluation of communication care plans (CCPs) for residents with cognitive-communication impairments in nursing homes by CNAs who did and did not receive professional support. Communication care plans are communication plans with the addition of autobiographical information. Twenty residents and ten CNAs from two nursing homes participated in the study. Once CCPs were created, CNA participants in one facility received support each day. Following two weeks, CNAs participated in a semi-structured interview. Interviews were transcribed and analyzed using open, axial and selective coding. Findings revealed a core category, meeting resident’s needs through professional support and communication, which describes the progressive process these CNAs underwent to effectively communicate with residents in nursing homes using CCPs. Evolution of this process occurred as CNA participants became familiar with residents. An underlying component facilitating this familiarity was support during CCP implementation. Initially, these CNAs had negative views about nursing home care because they were unsure how to communicate with residents and received little support from higher levels of nursing authority. Over time and with application of CCPs, CNAs became familiar with residents and their communication behaviors. Application of specific communication strategies on CCPs required ongoing support from the investigator/speech-language pathologist which was evident by the comments between CNA participants from each facility. Participants from both facilities reported positive experiences during application of the autobiographical information on the CCPs. This personal information coupled with increased knowledge about resident’s specific communication abilities fostered the formation of a relationship between residents and CNAs. In summary, support during application of CCPs supplements CNAs’ abilities to meet residents’ needs.

Background: Consumers have become more eco-friendly conscious than before, and therefore the demand for organic and environmentally-friendly products has increased during the past decade. Companies are committing to various green practices to improve company's image. Meanwhile, consumers usually have a positive attitude towards the companies who are practicing green concepts into their business operation. Purpose: The purpose of this study is to identify which factors are influential towards customers’ attitude towards the certified food service and the moderating role of green skepticism influences the relationship between green attributes and consumers’ attitude. In this study, it is also considered to research if LOHAS and non-LOHAS consumers’ attitudes towards certified food service differently influence their willingness to dine and willingness to pay the premium. Method: The data was collected with a structured and web-based survey. The valid study sample was 275. In order to answer the research questions and reach research purpose. The research model with 11 hypotheses was tested through hierarchy regression, linear regression, moderation regression and ANOVA analysis. The confirmatory analysis has been applied for testing construct validity. Besides, the descriptive statistics and construct variables correlation were demonstrated. Findings: In total, four hypotheses were rejected, and seven were supported. The result of data from the study showed that consumers’ attitudes towards certified food service were influenced by organic menu attribute, CSR attribute but not manifested on eco-friendly attributes. The study proved the positive relationship between consumers’ attitude and their willingness to dine and willingness to pay premium at certified food service. The study revealed that the LOHAS customer segment differs from the non-LOHAS consumer segment in the following ways: the attitude of LOHAS towards certified food service is more positive than the non-LOHAS and their willingness to dine and willingness to pay the premium is also much greater than the non-LOHAS. Whereas, there existed no significant relationship shifts between customer attitude and the green attributes regarding the certified food service when green skepticism was the moderator.   Implications: This paper assists researchers and practitioners by shedding light on the positive relationship between attitude and behavior intentions, the differences between LOHAS and non-LOHAS in regard to their more positive attitude and higher willingness to dine and willingness to pay premium in certified food service setting. Keywords: certified food service, LOHAS, consumers’ attitude, green skepticism, administrative CSR, green practices, organic menu

Improving patient safety through reduction of medical errors is a national priority. One of the strategies widely utilized to address this issue is the use of incident reporting systems. The purpose of this study was to describe factors that predict the likelihood that Certified Registered Nurse Anesthetists (CRNAs) will use incident reporting systems, guided by the theory of planned behavior (Ajzen, 1991). A non-experimental, correlational research design was utilized to achieve the study aims. Following IRB approval, a cross-sectional survey was administered electronically to a random sample of practicing CRNAs. Correlational analyses and a standard logistic regression were utilized to determine the relationship between cognitive factors and CRNAs' use of incident reporting systems. Two hundred and eighty-three practicing CRNAs participated in this study. These CRNAs value incident reporting, perceive social pressure to report, and feel in control over reporting, yet had not consistently used existing incident reporting systems in the past 12 months. A CRNA’s attitude toward reporting and the degree to which he or she perceived social pressure to report, were determined to be significant predictors of the likelihood that a CRNA would use an incident reporting system. Social pressure to report was the most important factor in the prediction model. The results of this study revealed that there are missed opportunities for learning from patient safety incidents in anesthesia practice. The information gained in this study has the potential to assist organizations in the design of strategies to promote incident reporting by practicing CRNAs.

Les techniques d’analyse thermique et de calorimétrie sont des méthodes d’essai largement utilisées dans les laboratoires d’analyse physico-chimique, pour des finalités de recherche ou de contrôle qualité. Comme tout appareil de mesure, un analyseur thermique ou un calorimètre doit être étalonné en température et en énergie avec des matériaux de référence certifiés. Les matériaux de référence recommandés correspondent généralement aux points fixes de l'échelle internationale de température (EIT-90), à savoir gallium, indium, étain, zinc et aluminium. Il existe peu de matériaux de référence certifiés au-dessus de 420 °C, alors que certains analyseurs thermiques peuvent être utilisés jusqu'à 1000 °C, voire au-delà.L’élaboration et la certification de matériaux de référence doivent employer des méthodes de mesure très précises avec un raccordement métrologique des mesures au système international d’unités (SI). Le Laboratoire Commun de Métrologie (LCM) s'est engagé dans le développement d'un moyen de référence métrologique en calorimétrie permettant des mesures précises en enthalpie de fusion et en capacité thermique massique sur la plage de température [23 °C, 1000 °C]. La solution métrologique retenue a été de modifier un calorimètre de type Calvet, et de mettre au point des procédures d’étalonnage et de mesure afin d’atteindre des incertitudes de mesures suffisamment faibles pour la certification des matériaux de référence.Dans ce travail, un système d'étalonnage fonctionnant à haute température a été spécifiquement conçu et intégré dans le calorimètre pour permettre l'étalonnage par substitution électrique. Ce système permet de réaliser successivement des étalonnages par effet Joule et des mesures d’enthalpie de fusion, sans modification des conditions expérimentales.Ce travail comprend également le développement des systèmes d’acquisition et traitement des résultats des mesures. La détermination de l'enthalpie de fusion de plusieurs métaux (indium, étain et argent notamment) avec une recherche des facteurs d’influence sur cette grandeur, et une estimation des incertitudes de mesure. La mesure de l’enthalpie de fusion d’un alliage eutectique argent-cuivre, candidat comme matériau de référence en énergie à 779 °C, est également présentée. / Differential scanning calorimeters are widely used in many academic and industrial laboratories to study the thermal behavior of materials for research or quality control. Like any measuring device, a thermal analyzer or calorimeter must be calibrated in temperature and energy with certified reference materials. Recommended reference materials generally correspond to fixed points of the International Temperature Scale (ITS- 90), namely: gallium, indium, tin, zinc and aluminum. However, there are few certified reference materials above 420 °C, while the operating range of some thermal analyzers and calorimeters exceeds 1000 °C.The certification of reference materials insures the metrological traceability of measurements to the International System of Units (SI). The LCM-LNE has been working in the development of a metrological standard facility for accurate measurements of the enthalpy of fusion and heat capacity in the temperature range [23 °C, 1000 °C]. The metrological approach is based on the modification of a commercial Calvet calorimeter and of the procedures implemented for calibration and measurement, so as to get measurement uncertainties sufficiently low to fulfill the objectives of the certification of reference materials.A new in-situ high temperature calibration system (constituted by a resistance wire wound around the crucible containing the material sample) was integrated into the calorimeter to perform the calibration by electrical substitution. The system allows both calibration and measurement without modification of the apparatus, so that the experimental conditions during both steps remain unchanged.This work also includes the development of data acquisition system and processing of measurement results. The determination of the enthalpy of fusion of several metals (indium, tin and silver in particular) with an estimation of the measurement uncertainty has been made. The measurement of the enthalpy of fusion of a silver-copper eutectic alloy, as candidate reference material at 779 °C, is also presented.

Pour réduire les coûts des systèmes embarqués, ces derniers sont livrés avec des micro-processeurs peu puissants. Ces processeurs sont dédiés à l'exécution de tâches calculatoires dont certaines, comme la transformée de Fourier rapide, peuvent s'avérer exigeantes en termes de ressources de calcul. Afin que les implémentations de ces algorithmes soient efficaces, les programmeurs utilisent l'arithmétique à virgule fixe qui est plus adaptée aux processeurs dépourvus d'unité flottante. Cependant, ils se retrouvent confrontés à deux difficultés: D'abord, coder en virgule fixe est fastidieux et exige que le programmeur gère tous les détails arithmétiques. Ensuite, et en raison de la faible dynamique des nombres à virgule fixe par rapport aux nombres flottants, les calculs en fixe sont souvent perçus comme intrinsèquement peu précis. La première partie de cette thèse propose une méthodologie pour dépasser ces deux limitations. Elle montre comment concevoir et mettre en œuvre des outils pour générer automatiquement des programmes en virgule fixe. Ensuite, afin de rassurer l'utilisateur quant à la qualité numérique des codes synthétisés, des certificats sont générés qui fournissent des bornes sur les erreurs d'arrondi. La deuxième partie de cette thèse est dédiée à l'étude des compromis lors de la génération de programmes en virgule fixe pour les briques d'algèbre linéaire. Des données expérimentales y sont fournies sur la synthèse de code pour la multiplication et l'inversion matricielles. / To be cost effective, embedded systems are shipped with low-end micro-processors. These processors are dedicated to one or few tasks that are highly demanding on computational resources. Examples of widely deployed tasks include the fast Fourier transform, convolutions, and digital filters. For these tasks to run efficiently, embedded systems programmers favor fixed-point arithmetic over the standardized and costly floating-point arithmetic. However, they are faced with two difficulties: First, writing fixed-point codes is tedious and requires that the programmer must be in charge of every arithmetical detail. Second, because of the low dynamic range of fixed-point numbers compared to floating-point numbers, there is a persistent belief that fixed-point computations are inherently inaccurate. The first part of this thesis addresses these two limitations as follows: It shows how to design and implement tools to automatically synthesize fixed-point programs. Next, to strengthen the user's confidence in the synthesized codes, analytic methods are suggested to generate certificates. These certificates can be checked using a formal verification tool, and assert that the rounding errors of the generated codes are indeed below a given threshold. The second part of the thesis is a study of the trade-offs involved when generating fixed-point code for linear algebra basic blocks. It gives experimental data on fixed-point synthesis for matrix multiplication and matrix inversion through Cholesky decomposition.
