Öman, Lundin Gustav. „Supervision for drone flight safety“. Thesis, Toulouse, ISAE, 2020. http://www.theses.fr/2020ESAE0006.

L'utilisation croissante des drones et leur intégration dans le trafic aérien nécessite de fournir un certain nombrede garanties de sûreté et de preuves de fonctionnement. La sécurité du vol est directement tributaire de laprécision et de la fiabilité de la localisation qui est généralement obtenue par une fusion multi-capteurs, réaliséeà l'aide d'un filtre estimateur. Ce travail de thèse s'intéresse au problème de la navigation tolérante aux défautset aux pannes capteurs dans le cas de capteurs non redondés. L'objectif principal est de proposer des méthodeset des architectures d'estimations de l'attitude et de la position qui permettent de préserver la justesse del'estimation, mais aussi d'améliorer sa consistance et son intégrité, même en cas de perturbations prolongéesdes capteurs. Un premier axe de travail concerne l'estimation et le rejet de biais multiples et fréquents sur uncapteur de position, comme peut y être soumis un récepteur GNSS (multi-trajets), ou un capteur visuel (erreurde poursuite). Une architecture de détection et de correction de l'estimation de position a été développée pourcela et vient compléter les méthodes existantes basées sur le GLR. Un second axe de travail a été de proposerune architecture d'estimation de l'attitude qui soit robuste aux perturbations magnétiques et aux accélérationsspécifiques. Elle comporte principalement trois briques: (1) Des modèles de performance permettent d'estimer lessorties capteurs nettoyées au mieux des perturbations; (2) Une étape de consolidation de mesures utilise des testsstatistiques pour sélectionner les signaux à fusionner entre les mesures brutes ou nettoyées, ou simplement rejeterles signaux dans les cas où la consolidation échoue; (3) Un estimateur d'attitude basé sur un filtre de Kalmanfusionne les mesures consolidées, avec des propriétés de découplage vis-à-vis des perturbations résiduelles, ainsiqu'un modèle de biais saturé. Les algorithmes d'estimation de position et attitude ont été validés en simulationet séparément lors de diverses campagnes d'essais expérimentalesThe ever-increasing use of drones and their integration within the existing air trafic demand a certain number ofguarantees of safety and functional proofs. The flight safety is directly impacted by the precision and reliability ofthe localisation which is achieved most of the time by a multi-sensor fusion, itself provided by a state estimatingfilter. The work of this thesis focuses on the problem of fault tolerant navigation and sensor fault in the nonredundantsensor case. The main objective is to propose methods and architectures for attitude and positionestimation providing a correct estimation, but also improving its consistency and integrity, even in the case oflong lasting sensor perturbations. A first line of work concerns the estimation and rejection of multiple andfrequent biases on a position sensor, which is often the case for a GNSS receiver (multi-path errors), or a visualsensor (tracking errors). An architecture for bias detection and correction of the estimated position has beendeveloped to this end, to complement standard methods based on the GLR. A second line of work has beento propose an attitude estimation architecture robust to magnetic disturbances and specific accelerations. It isdivided into three principal blocks: (1) Sensor performance models allowing the estimation of sensor outputscleaned as well as possible from perturbations; (2) A measurement consolidation stage utilises statistical teststo select the signals to fuse between the raw measurements and the cleaned ones, or simply reject the signalsin case the consolidation fails; (3) An attitude estimator based on a Kalman filter merges the consolidatedmeasurements, with decoupling properties to mitigate the effect of residual perturbations, and a saturated biasmodel. The algorithms for position and attitude estimation have been validated in simulation and separatelyduring various experimental test campaigns

Educators are compelled by federal and state legislation to investigate multiple aspects of the school organization to address factors that may increase student achievement. This study addressed this issue by investigating organizational health and school safety in urban elementary schools and their relationships to student achievement. The study explored elementary school teachers' perceptions regarding organizational health and school safety. These data were correlated to student achievement on the Virginia Standards of Learning Tests in English and mathematics for fifth grade.;The Organizational Health Inventory (OHI) for elementary schools was used to survey teachers' perceptions of institutional integrity, collegial leadership, resource influence, teacher affiliation, and academic emphasis in 24 urban elementary schools in Virginia. The School Safety Survey (SSS) gathered data on teachers' perceptions of school safety. The fifth grade Virginia Standards of Learning (SOL) tests in the areas of English and mathematics were the measurement tools for student achievement. This study compared the overall health indices and the subscale scores of organizational health to school safety, achievement in English, and achievement in mathematics. It further investigated the relationship between school safety and achievement in English as well as achievement in mathematics.;The study showed that there was a strong positive relationship between organizational health and safety, organizational health and student achievement in both English and mathematics, and school safety and student achievement in both English and mathematics. Regression analysis of the subscales of organizational health revealed that academic emphasis had a strong independent effect on student achievement in English and mathematics. Correlation and regression analysis with regard to organizational health and safety indicated that organizational health had an independent effect on English, but not mathematics.

Research shows that risk factors may be useful clues for predicting students' potential for engaging in weapon-carrying behavior. Law makers on every level-federal, state, and local- deem the presence of weapons on school grounds to be a serious problem and a violation of school policy. A large, urban school system has put forth sustained and costly efforts to prevent students from carrying weapons to school; yet students continue to carry weapons to school in this district. The purpose of this study was to use archival data collected as part of the school system's everyday practice to identify risk factors for students carrying weapons to school. Bandura's social learning theory guided this quantitative ex-post facto study. Six risk factors related to students' weapon-carrying behavior were examined: gender, prior fights, suspensions, race, academic achievement, and time of school day/year. Risk factors were compared for identified weapon carriers (n = 605) and non-weapon carriers (n = 605) using chi-square tests and a logistic regression analysis. Results showed that gender, prior fights, suspensions, and race were significant risk factors for weapon carrying. Students in this district who received 5-14 suspensions had a 1 in 4 chance of being a weapon carrier. Males as well as Black students and White students were 3 times more likely to carry a weapon to school. A pattern of fighting also correlated with an increased incidence of carrying a weapon to school. These data may help this school district and other school districts like it to provide better prevention strategies and enhance policy decisions by identifying students who are at high risk of carrying a weapon on school grounds.

Occupational risk management can be a catalyst in generating superior returns for all stakeholders on a sustainable basis. A number of companies in South Africa have implemented Cardinal Rules of Safety adopted from international companies to ensure the safety of their employees. The purpose of this study was to measure the impact of the cardinal rules on employee safety behaviour implemented at power stations in Mpumalanga.
The empirical study was done by using a questionnaire as measuring instrument. The questionnaire was developed from a literature review and contains questions and items relevant to the initial research problem. The questionnaire comprised of five–point Likert scale type questions.The convenience sampling method was applied identifying 90 participants at three different power stations in Mpumalanga taking part in the study.
Statistical analysis was performed by the Statistical Consulting Service of the North–West University using SPSS. Cronbach’s alpha co–efficients was used to determine the reliability of the factors. Descriptive statistics (Mean, standard, deviation, were used in the compiling of the profile of the results. While Spearman’s rho correlation coefficient was calculated to identify practically significant associations between variables and factors
The research findings suggest that there is practical significant correlation between the factors that were measured. The opinion given by respondents suggests that cardinal rules of safety were implemented, given all the necessary support by management and enforced throughout the organisation.Thesis (MBA)--North-West University, Potchefstroom Campus, 2012.

Bullying remains a pervasive problem in schools across the nation. Various detrimental social, psychological, emotional, and academic effects can result from involvement in bullying regardless of whether a student is the perpetrator, victim, witness, or a combination of the three. Recent literature has made significant connections between a school’s overall climate and bullying behaviors, suggesting the need for school-wide interventions to combat the problem. As a part of school climate, unstructured areas such as the playground, have been targeted as a critical area in need of support. Researchers attribute poor safety on the playground to lack of adequate and trained supervision. Fortunately, Systematic Supervision is a training program based in empirically supported principles that shows likelihood for success to improve climate and reduce bullying behaviors on the playground and the school as a whole (Smith, & Sprague, 2011). Yet, this program has not been thoroughly evaluated in peer reviewed journals. The purpose of this study was to evaluate the effectiveness of Systematic Supervision for improving playground safety, reducing bullying behavior, and enhancing school climate. Behavioral observations and student and teacher school climate surveys collected from 35 schools over two years were assessed. Comparisons were made between schools that received the intervention with those that were wait-listed controls. Results of the study suggest that Systematic Supervision is an effective means of training playground monitors to use active supervision behaviors. Unfortunately, no significant connections could be made with regard to the implementation of Systematic Supervision and subsequent changes in student or teacher perceptions of safety, in perceptions of school climate, or in bulling behaviors. A discussion of the results and their implications is included in detail.

Les systèmes actuels deviennent chaque jour de plus en plus complexe; à la distribution s’ajoutent les contraintes temps réel. Les méthodes classiques en charge de garantir la sûreté de fonctionnement, comme le test, l’injection de fautes ou les méthodes formelles ne sont plus suffisantes à elles seules. Afin de pouvoir traiter les éventuelles erreurs lors de leur apparition dans un système distribué donné, nous désirons mettre en place un programme, surveillant ce système, capable de lancer une alerte lorsque ce dernier s’éloigne de ses spécifications ; un tel programme est appelé superviseur (ou moniteur). Le fonctionnement d’un superviseur consiste simplement à interpréter un ensemble d’informations provenant du système sous forme de message, que l’on qualifiera d’évènement, et d’en déduire un diagnostic. L’objectif de cette thèse est de mettre un place un superviseur distribué permettant de vérifier en temps réel des propriétés temporelles. En particulier nous souhaitons que notre moniteur soit capable de vérifier un maximum de propriétés avec un minimum d’information. Ainsi notre outil est spécialement conçu pour fonctionner parfaitement même si l’observation est imparfaite, c’est-à-dire, même si certains évènements arrivent en retard ou s’ils ne sont jamais reçus. Nous avons de plus cherché à atteindre cet objectif de manière distribuée pour des raisons évidentes de performance et de tolérance aux fautes. Nous avons ainsi proposé un protocole distribuable fondé sur l’exécution répartie d’un réseau de Petri temporisé. Pour vérifier la faisabilité et l’efficacité de notre approche, nous avons mis en place une implémentation appelée Minotor qui s’est révélée avoir de très bonnes performances. Enfin, pour montrer l’expressivité du formalisme utilisé pour exprimer les spécifications que l’on désire vérifier, nous avons détaillé un ensemble de propriétés sous forme de réseaux de Petri à double sémantique introduite dans cette thèse (l’ensemble des transitions étant partitionné en deux catégories de transitions, chacune de ces parties ayant sa propre sémantique).

Der volle Inhalt der QuelleAnnotation:
La surveillance visuelle des objets dynamiques dans les carrefours routiers a été un sujet de recherche majeur au sein des communautés de vision par ordinateur et de transports intelligents, ces dernières années. De nombreux projets ont été menés afin d’améliorer la sécurité dans le contexte très particulier des carrefours. Notre analyse approfondie de l’état de l’art révèle que la majorité des systèmes en bord de voie, utilisent la vision monoculaire. Dans cette thèse, nous présentons un systèmenon-intrusif, de stéréovision-fisheye à large entraxe. Le dispositif proposé est particulièrement adapté aux carrefours ruraux ou sans signalisation. Notre objectif principal est la localisation des véhicules afin de reconstruire leurs trajectoires. Pour ce faire, l’estimation de la calibration extrinsèque entre les caméras est nécessaire afin d’effectuer des analyses à l’échelle métrique. Cette tâche s’avère très complexe dans notre configuration de déploiement. En effet la grande distance entre les caméras, la différence de vue et la forte présence de végétation, rendent inapplicables les méthodes de calibration qui requièrent la mise en correspondance d’images de mires. Il est donc nécessaire d’avoir une solution indépendante de la géométrie de la scène. Ainsi, nous proposons une méthode automatique reposant sur l’idée que les véhicules mobiles peuvent être utilisés comme objets dynamiques de calibration. Il s’agit d’une approche de type Structure à partir du Mouvement, découplée en l’estimation de la rotation extrinsèque à partir de points de fuite, suivie du calcul de la translation extrinsèque à l’échelle absolue par mise en correspondance de plans virtuels. Afin de généraliser notre méthode, nous adoptons le modèle de caméra sphérique sous l’hypothèse d’un mouvement plan. Des expérimentations conduites en laboratoire, puis dans des carrefours en Normandie, permettent de valider notre approche. Les paramètres extrinsèques sont alors directement exploités pour la trajectographie métrique des véhicules, en vue d’évaluer le risque et procéder à un diagnostic des intersections ruralesVisual surveillance of dynamic objects at road intersections has been an active research topic in the computer vision and intelligent transportations systems communities, over the past decades. Several projects have been carried out in order to enhance the safety of drivers in the special context of intersections. Our extensive review of related studies revealedthat most roadside systems are based on monocular vision and provide output results generally in the image domain. In this thesis, we introduce a non-intrusive, wide-baseline stereoscopic system composed of fisheye cameras, perfectly suitable for rural or unsignalized intersections. Our main goal is to achieve vehicle localization and metric trajectory estimation in the world frame. For this, accurate extrinsic calibration is required to compute metric information. But the task is quite challenging in this configuration, because of the wide-baseline, the strong view difference between the cameras, and the important vegetation. Also, pattern-based methods are hardly feasible without disrupting the traffic. Therefore, we propose a points-correspondence-free solution. Our method is fully-automatic and based on a joint analysis of vehicles motion and appearance, which areconsidered as dynamic calibration objects. We present a Structure-from-Motion approach decoupled into the estimation of the extrinsic rotation from vanishing points, followed by the extrinsic translation at scale from a virtual-plane matching strategy. For generalization purposes we adopt the spherical camera model under the assumption of planar motion. Extensive experiments both in the lab and at rural intersections in Normandy allow to validate our work, leading to accurate vehicle motion analysis for risk assessment and safety diagnosis at rural intersections

The purpose of this study was to compare the safety outcome for children who remained at home under the supervision of the State and children who were placed in foster care. There were two variables: (1) services as the independent variable, and (2) placement outcomes as the dependent variable.
A correlational research design was used to analyze the data. An on-site review instrument was used to collect data from three county Departments of Social Services in South Carolina. Additionally, a case record analysis and a face-to-face interview approach were utilized.
The conclusion drawn from this study is that families are confronted with many stressors and a lack of resources that affect their behavior. The researcher found that in cases where services were provided, maltreated children could remain safely in their homes. For future child maltreatment interventions, this could provide a comprehensive approach to services that might avoid unnecessary out-of-home placements.

Injury is the leading cause of death and disabilityamong American children, and most injuries to children aged 1-5 years occur at home. Factors associated with increased risk for unintentional injury to young children include an overcrowded home environment, low SES, and living with a mother who is young, less educated, more emotionally overwhelmed, and less protective in her supervision, attributes characteristic of many adolescent mothers. Previous research suggests that teaching parents basic child behavior management techniques can reduce child dangerous behavior (Mathews, et al., 1987; Powers & Chapieski, 1986), but these interventions have not addressed the lack of knowledge about child development common among adolescent parents.
The current study employed a multiple-baseline design across subjects to assess the impact of a 6-week in home educational and behavioral treatment. Observable home hazards, supervisory skill, maternal efficacy, parenting stress, and cognitive readiness to parent were examined in four adolescent mothers (aged 16-19), in addition to the dangerous behavior of their children (aged 16-24 months). Mothers received education about child development and sensitive parenting, as well as training in home safety and child behavior management. Child dangerous behavior and maternal supervisory skill and positive behavior were assessed in weekly 20-minute videotaped mother-child interactions. Pre- and post- measures of parenting stress, cognitive readiness to parent, and maternal efficacy related to parenting and child safety were assessed by self-reports. Treatment resulted in improvements in mother positive behavior and knowledge of child development and in reductions of parenting stress, observable home hazards, and child dangerous behavior. A 2-month follow-up revealed some minimal maintenance of treatment gains suggesting additional booster sessions are needed for longer-term gains of reduced injury risk.Ph. D.

Der volle Inhalt der QuelleAnnotation:
Le véhicule autonome est un véhicule qui se conduira, à terme, sans aucune intervention du conducteur, quelle que soit la situation de conduite. Ce véhicule comprend une nouvelle fonction, nommée fonction AD, pour Autonomous Driving, en charge de la conduite autonome. Cette fonction peut se trouver dans des états différents (Active, Disponible par exemple) selon l'évolution des conditions environnementales. Le changement de ses états est géré par une fonction de Supervision, nommée Supervision AD. Le principal objet de ces travaux consiste à garantir que la fonction AD se trouve constamment dans un état sûr. Ceci revient à s'assurer que la Supervision AD respecte l'ensemble des exigences fonctionnelles et de sûreté qui spécifient son comportement. Ces deux types d'exigences sont émis par deux métiers distincts : l'Architecte Métier Système (AMS) et le pilote Sûreté de Fonctionnement (SdF). Ces deux disciplines d'ingénierie, bien qu'elles contribuent à la conception d'une même fonction, se distinguent en de nombreux points : objectifs, contraintes, planning, outils... Dans notre cas d'étude, ces différences s'illustrent par les exigences considérées : les exigences fonctionnelles sont allouées à la fonction AD globale, tandis que les exigences de sûreté spécifient le comportement de sous-fonctions locales redondantes assurant une continuité de service en cas de défaillance. La mise en cohérence de ces deux perspectives métier au plus tôt dans le cycle de conception et dans un contexte industriel, est la problématique centrale traitée. Les enjeux de SdF soulevés par le véhicule autonome rendent ce problème primordial pour les constructeurs automobiles. Afin de répondre à ces préoccupations, nous avons proposé une démarche outillée et collaborative de conception sûre de la Supervision AD. Cette démarche est intégrée dans les processus normatifs en vigueur (normes ISO 15288 et ISO 26262) ainsi que dans les processus de conception internes chez Renault. Elle est fondée sur la vérification formelle par model checking, la composition parallèle d'automates finis et l'expertise métier. Cette démarche prône l'utilisation d'un même formalisme (l'automate à états finis) par les deux métiers pour mener à bien des activités partageant un objectif de modélisation commun : la vérification d'exigences de comportement en phase amont de conception. Une méthode pour traduire les exigences en propriétés formelles et construire les modèles d'état a été déployée. Il en résulte une consolidation progressive des exigences traitées, initialement rédigées en langage naturel. Les potentielles ambigüités, incohérences et incomplétudes sont exhibées et traitéesThe Autonomous Vehicle is meant to drive itself, without any driver intervention, whatever the driving situation. This vehicle includes a new function, called AD, for Autonomous Driving, function. This function can be in different states (Available, Active for example) according to environmental conditions evolution. This states change is managed by a supervision function, named AD Supervision. The main goal of my works consists in guaranteeing that AD function remains always in a safe state. In other words, the AD Supervision must always respect all the functional and safety requirements that specify its behavior. These two requirements types are produced by two different professions: the System Architect (SA) and the Safety Engineer (SE). These two fields contribute to the design of the same function but distinguish at several aspects: objectives, constraints, planning, tools… In our case study, these differences are illustrated by considered requirements: the functional requirements are allocated to global AD function, while the safety requirements specify the behavior of local redundant sub-functions ensuring a continuous service in case of failure. The consistency of the two perspectives as early as possible in the design phase and in an industrial context, is the central problematic addressed. The safety issues due to Autonomous Vehicle make this topic essential for the automotive manufacturers. To meet these concerns, we proposed a tooled and collaborative approach for safe design of AD Supervision. This approach is integrated in the normative processes (standards ISO 26262 and ISO 15288) as well as in the internal design processes at Renault. It is based on formal verification by model checking, parallel composition of finite sate automata and technical expertise. This approach advocates the utilization of a same formalism (state automata) by the two professions to perform activities sharing a common goal: behavior requirements verification in preliminary design phase. A method to translate requirements into formal properties and to build state models has been deployed. The result is a progressive consolidation of treated requirements, initially expressed in free natural language. The potential ambiguities, inconsistencies and incompleteness are exhibited and treated. Two main contributions are in this way illustrated: highlighting of several formal credible (i.e. validated by expertise) specifications from informal requirements; and precise definition of technical expertise role (milestones, planning). However, this reinforcement – in silos – of the two profession viewpoints does not guarantee that they are mutually consistent. Thus, we proposed a convergence method, relying on expertise and on parallel composition of state automata, for the comparison of local and global views

The use of electronic monitoring (EM) as a tool to supervise high-risk offenders has increased in the field of criminal justice in the state of Texas. Although EM is now widely used to supervise high-risk offenders to prevent them from committing further crimes, it is unclear whether EM has achieved the purpose of reducing reoffenses during parole supervision. Hirschi's social bond theory, which was later developed into social control theory, was used as the framework for this general qualitative study to explore retired parole officers' perceptions concerning whether EM is successful in preventing high-risk offenders from committing additional crimes. Interview data were collected from 10 retired parole officers who supervised high-risk offenders on EM in Harris County, Texas. The findings revealed that the 10 officers perceived EM to be an effective tool, but they perceived the role of capitalizing on positive social bonds was equally important in controlling criminal behavior. Specifically, the officers perceived that their bond with the high-risk offenders on EM could diminish offenders' propensity to commit new crimes. Opportunities for positive social change stemming from this study include recommendations to the Texas Department of Criminal Justice to develop policies and training that is consistent with social bond theory, and retrain parole officers to emphasize to offenders positive contacts and relationship with family and continuing employment during the term of parole release in order to reduct opportunities for reoffense and futher victimization to the community.

This research examined the knowledge level and perceptions of 300 randomly selected school leaders in the Commonwealth of Virginia concerning the discipline provisions of the Individuals with Disabilities Education Act of 1997 (IDEA 97). The overarching questions answered in the study were (1) to what extent are school leaders aware of the existing discipline provisions of IDEA 97 which have been in place since 2001; and (2) how do school leaders view the impact of those provisions on their ability to maintain a safe learning environment for all?;Findings resulted in one significant difference (p<.05) among school leaders in the sub-domain of Knowledge. Elementary leaders reported a significantly lower level of knowledge regarding the discipline provisions of IDEA 97 than did their middle school peers. School leaders across knowledge domains and school levels reported that the discipline provisions of IDEA 97 did not negatively impact their ability to maintain safe schools. Moreover, professional development was identified by school leaders in the study as a high need to manage the discipline provisions of IDEA 97 across all school levels.

This study investigates the apparent threat assessment priorities of potential risks to safety in the school environment in the United States and whether stakeholders in Florida private schools that serve exceptional students agree with the priority given to specific identified potential threats. Faculty and staff, high school students, and the students’ parents and guardians at four Florida private schools for exceptional students rated their perceptions of the severity and likelihood of occurrence of nine potential threats identified in a review of federal and Florida state school safety laws and national and state government surveys of incident occurrences. Results showed that although violent potential threats such as an armed intruder, students bringing weapons to school, and physical assaults received priority attention in federal and state school safety laws, stakeholders in Florida private schools for exceptional students indicated that threats of a more personal nature—such as bullying, sexual harassment, and cyberbullying—were the most significant risks to the safety of their school environment. All three respondent subgroups, however, reported high ratings of their overall feelings of safety at their schools.

Nursing response to medical emergencies has been an ongoing issue in immigration detention centers. Lack of teamwork and poor communication with medical and security staff have resulted in detainees sustaining injuries during medical emergencies. This project was developed to persuade Immigration and Customs Enforcement Health Service Corps (IHSC) leaders to consider piloting the TeamSTEPPS emergency response curriculum for nurses working in the immigration detention center. Tuckman and Jensen's model of group development will provide guidance to IHSC leaders in understanding the transformational stages of forming a successful team. TeamSTEPPS will address gaps in emergency health care competency by improving collaboration, communication, and detainee outcomes. Evaluation questionnaires will be offered after each training module and several months after the conclusion of the program. Questionnaires will be distributed, analyzed, and interpreted by IHSC leadership or their designee. Implementation of the Team STEPPS curriculum may result in increased staff morale, decreased staff turnover, and improved detainee outcomes.

The purpose of this study was to explore the relationships among hardiness, health and burnout and to investigate the relationships of the subscales of hardiness to health and to the subscales of burnout among teachers in the Sullivan County School System. The Hardiness Test was used to measure hardiness and the Maslach Burnout Inventory Form Ed to measure burnout. Results of the Health Evaluation and Risk Test was reported on the Educators Demographic Data Survey. The study sample consisted of 501 teachers. A statistically significant relationship was revealed between hardiness and health; among the hardiness subscales, commitment accounted for the largest amount of variance in health. Multiple regression was used to analyze the relationships among the subscales of hardiness and the subscales of burnout. Of the hardiness subscales, commitment and control equally accounted for the greatest amount of variance in depersonalization and personal accomplishment. To determine the extent to which the subjects' demographic variables were related to any study variables, correlation coefficients were computed between demographic variables and each of the study variables. While age, years teaching experience, and level taught were significantly related to the study variables, the extremely low correlations indicate that only 1% of the variance in these three variables were explained by the study variables, preventing meaningful interpretation. Kobasa's health and hardiness theory is supported by the results of this study. These results also support previous research findings which suggest that hardiness buffers against burnout.

Active shooter events in K-12 schools have increased since 1990, and developing response policies to such events is a responsibility of school personnel. A paucity of data regarding options-based response practices existed with no focus on policy processes. The purpose of this qualitative multi-case study was to describe the decision-making processes used in school districts when approving the inclusion of options-based responses to active shooter events in Emergency Operations Plans (EOPs). The research questions addressed processes that shaped the development of options-based responses to active shooter policies in 3 K-12 school districts within the Midwest. The conceptual framework was informed by the theory of policy paradox and the concepts of situational awareness and resilience. Structured interviews were conducted with 12 school personnel and safety professionals involved in 3 high schools; EOPs and state and federal regulations and guidelines were reviewed. An analysis of the interview responses and document reviews using four levels of descriptive coding required a cross-case analytic technique to discover patterns, connections, and themes. Law enforcement and school personnel worked together to create policy and to implement trainings related to options-based response. Results included enhancing situational awareness and empowering teachers and students to become responsible for their safety. These findings can be used to inform and guide school leaders in their efforts to make policy and implementation decisions regarding active shooter policies in EOPs. The potential for social change exists in more school personnel understanding and implementing options-based response policies and making the lives of K-12 students safer.

Recent high profile food safety incidents in the United Kingdom have shaken
consumer confidence in food products. Consumer perception of risk is seen to be
very relevant to food safety issues. The impact of this perceived risk on purchase
behaviour is also critical to the development of risk management strategies by
authorities responsible for public health and the food industry. Focusing on fresh
chicken meat products, this study explored the relationship between food risk
characteristics, consumer perception of food safety related risk, consumer purchase
behaviour and actions that can be taken to reduce the exposure to food risk.
Following an extensive literature review, an exploratory study in the form of face-toface
interviews was carried out to clarify the main concerns of food hazards, and to
identify the items of perceived consequent loss and risk reducing strategies adopted
by consumers. The findings were verified through a quantitative survey of 200
respondents. The data was presented in the form of Structural Equation Modelling,
and analysed by the LISREL 8.30 statistical package. The results showed that
consumer risk perception was affected by a range of risk characteristics, such as
consumer concern about the severity of the food risk, and the potential long-term
adverse effect on future generation and environment. The main elements of perceived
loss associated with food safety were health, financial, time, lifestyle and taste losses,
and these were shown to have a negative effect on purchase likelihood. Two other
risk characteristics namely, perceived knowledge and own control of the food risk
were found to be linked directly and positively to consumer purchase likelihood. Risk
reducing strategies such as branded product, product quality assurance and product
information adopted by consumers were identified and found to be consistent with the
marketing strategies used by the food industry. These risk-reducing strategies have a
negative relationship with consumer risk perception.
This study presented empirical evidence for characterising types of food risks and
explains how food risks and risk reducing strategies affect consumer risk perception
as well as purchase likelihood. Consequently, two quantitative consumer food
purchase models were developed. These models can help the government and the food
industry to identify key factors to develop systematic strategies for risk management
and risk communication in order to allocate resources efficiently and effectively. They
can also use these models to measure the effectiveness of their risk management
policy in the times of concern about food safety.
This study recommends further research to apply these models in other types of food
products and other types of risk, such as chemical risk, and technological risk, in
particular for those risks which are beyond the control of consumers. The differences
in risk perception between cultures and socio-economic groupings should be explored
further. This is a valid topic for further research and provides potential benefits for
consumers and food industry as a whole.

Research suggests that individuals who perceive their work as a calling (a deep passion and meaningfulness associated with a certain domain) experience a variety of positive outcomes such as occupational identification, career decidedness, and job satisfaction. Utilizing the tenets of Social Exchange Theory and the Job Demands Resources Model, I proposed that individuals with greater calling toward their occupation will report higher safety motivation and safety compliance. However, under conditions of high workload this relationship would be attenuated. Further, by the same rationale, individuals with lower calling will report lower safety outcomes, yet I proposed that this relationship is mitigated under conditions of high supervisor support. The study was conducted with a sample of 183 participants collected across three forests within the United States Forest Service. Although the hypotheses in the study were not supported, this study provides theoretical groundwork elucidating the link between calling and the examined outcome - safety. This, in turn, will aid in the development of a number of potential research avenues for safety scholars, with many practical implications. Further, an examination of calling with other collected variables within this industry provides avenues for future research in the calling domain. The investigation of moderators may help to explain the conflicting results found in the calling literature. Finally, this study furthers our understanding of safety, workload, and supervisor support within a "helping field."

This applied dissertation was designed to provide a better understanding of the effectiveness of out-of-class safety net corrective instructional activity practices conducted beyond regular classroom instruction for lower secondary level (9th- and 10th- grade high school) students within mastery learning educational environments. The study was designed to shed light on the impact and implications of these practices on Bloom’s vanishing point (Bloom, 1971) and Arlin’s leveling effect (Arlin & Westbury, 1976). Seven mastery learning structured international schools in geographic proximity, of similar size, and utilizing the same program of study were used in this study. Three of the schools that employed a safety net program were the basis of this study, and the four schools that did not have in place a safety net program were used as a control for this observational research.
Normed Measures of Academic Progress (MAP) RIT scores (Northwest Evaluation Association, 2005), grade point averages, and safety net program data were used in a series of case-control tests to determine the effectiveness of out-of-class corrective instructional activity safety net programs for above-average and below-average achieving students. The mean study and control group RIT percentile ranking scores for the students was nearly 1 standard deviation above the averages reported by the Northwest Evaluation Association (2005), so these relative comparisons involved bright students. This large volume of data enabled analysis of the effects of out-of-class safety net activities on school-wide and individual improvement in literature, writing, mathematics, and comprehensive results.
Series of conclusive nonparametric analysis were used instead of normal distribution tests because of the out-of-bounds skewed nature of the data. Analysis of the data suggested that safety netting programs benefit all students, irrespective of whether or not students received out-of-class corrective instructional activities. The MAP RIT scores of below- average achieving students were not affected by attending a school with a safety net program but their GPA results improved in all subjects. Arlin’s leveling effect (Arlin & Westbury, 1976) most likely accounted for improvement of MAP RIT scores for above- average students who attended a school with a safety net program but their GPA results were not affected. These contrasting benefits masked the school-wide test results, which suggested that a school district might not realize an overall increase in MAP RIT and GPA results when adopting a safety net program. Students identified in need of safety netting services benefited by having been placed in the program up to twice in any respective course, but a point of diminishing returns was reached when a student fell 3 or more units behind in a course in relation to the progress of the class.

Researchers continue to emphasize the important role supervisors have in creating a safe space for supervisees to effectively navigate and engage in honest multicultural conversations while also addressing potential biases (e.g., Ancis & Marshall, 2010). However, much of the literature on multicultural supervision provides limited guidance on what characteristics define a safe space. The purpose of this study was to examine accounts of counseling psychology graduate students to learn about their understanding and definitions of safe space and brave space within multicultural supervision, using grounded theory methodology (Corbin & Strauss, 2015). Specifically, the purpose of the study was threefold: (a) to define what a safe space and a brave space is from supervisees’ perspective, (b) to determine if the concept of a safe space is viewed similarly or differently to a brave space, and (c) to identify specific behaviors and interventions that supervisors perform that make a supervisee feel they are in a safe or brave space. Results yielded a model characterized by three core dimensions that comprise safe and brave spaces including: (a) safety within the physical space, (b), definitions and use of brave and safe spaces, and (c) supervisor actions and behaviors. This study adds to the current multicultural supervision training scholarship by providing new perspectives on how supervisees in counseling psychology doctoral programs make sense of safe and brave spaces during multicultural supervision and what supervisors can do to create such spaces.

This thesis develops an advanced battery monitoring and control system based on the electrochemical principles that govern lithium-ion battery dynamics. This work is motivated by the need of having safer and better energy storage systems for all kind of applications, from small scale portable electronics to large scale renewable energy storage. In this context, lithium-ion batteries have become the enabling technology for energy autonomy in appliances (e.g. mobile phone, electric vehicle) and energy self-consumption in households. However, batteries are oversized and pricey, might be unsafe, are slow to charge and may not equalize the lifetime of the application they are intended to power. This work tackles these different issues.This document first introduces the general context of the battery management problem, as well as the particular issues that arise when modeling, supervising and controlling the battery short-term and long-term operation. Different solutions coming from the literature are reviewed, and several standard tools borrowed from control theory are exposed. Then, starting by well-known contributions in electrochemical modeling, we proceed to develop reduced-order models for the battery operation including degradation mechanisms, that are highly descriptive of the real phenomena taking place. This modeling framework is the cornerstone of all the monitoring and control development that follows.Next, we derive a battery diagnosis system with a twofold objective. First, indicators for internal faults affecting the battery state-of-health are obtained. Secondly, detection and isolation of sensor faults is achieved. Both tasks rely on state observers designed from electrochemical models to perform state estimation and residual generation. Whereas the former solution resorts to system identification techniques for health monitoring, the latter solution exploits fault diagnosis for instrumentation assessment.We then develop a feedback battery charge strategy able to push in performance while accounting for constraints associated to battery degradation. The fast and safe charging capabilities of the proposed approach are ultimately validated through long-term cycling experiments. This approach outperforms widely used commercial charging strategies in terms of both charging speed and degradation.The main contribution of this thesis is the exploitation of first principles models to develop battery management strategies towards improving safety, charging time and lifetime of battery systems without jeopardizing performance. The obtained results show that system and control theory offer opportunities to improve battery operation, aside from the material sciences contributions to this field.Doctorat en Sciences de l'ingénieur et technologie

Murphy, Lauren Ann. „A Macroergonomics Approach Examining the Relationship between Work-family Conflict and Employee Safety“. PDXScholar, 2011. https://pdxscholar.library.pdx.edu/open_access_etds/214.
Der volle Inhalt der QuelleAnnotation:
In 2008, there were more than 5,200 workplace fatalities in the United States (BLS, 2010b). During the same time period, U.S. employees missed almost 1.1 million days from work (BLS, 2010c). Accidents are unexpected outcomes that result not only from individuals' behaviors, but from contextual factors (Krause, 1997; Reason, 1990). Therefore, unsafe behaviors have to be interpreted according to a combination of what is occurring in the environment and what the individual is doing in that environment. The present study sought to create a more comprehensive model of safety by means of macroergonomics. Macroergonomics utilizes sociotechnical systems theory to posit that a work system is composed of a personnel subsystem (i.e., ways individuals perform tasks), a technological subsystem (i.e., tasks to be performed), and external factors (Hendrick, 2002a). Perceived control over work hours, an aspect of the technological subsystem, was examined as an antecedent of work-family conflict. Supervisor instrumental support, an aspect of the personnel subsystem, was examined as a moderator of the relationships between perceived control over work hours and work-family conflict. Supervisors have an imperative role in employees' perception of control over their work hours (Kelly & Moen, 2007). Supervisor instrumental support was also hypothesized to moderate the relationships between work-family conflict and safety performance. Supervisors who support their employees in their work-family matters exceed mandatory requirements set forth to protect workers' safety and health (Mearns, Hope, Ford, & Tetrick, 2010). A majority of the 360 participants in the present study were grocery store employees who worked in the front end of the store as cashiers. Job tenure in this particular grocery store chain was an average of 7 years (SD = 5.96) and the average number of hours worked per week was 31 (SD = 8.55). The employees were an average age of 38 years old (SD = 15.25). Two hundred and sixty-two (73%) of the participants were female, 330 (92%) were White, 196 (55%) employees were married or living as married, 146 (41%) employees identified themselves as parents with children living at home, and 58 (16%) employees provided elder care. The data were analyzed using a moderated mediation model. An employee's perceived control over his/her work hours was negatively associated with work-to-family and family-to-work conflict. Work-to-family conflict was not significantly associated with either safety compliance or participation. In contrast, family-to-work conflict was significantly associated with both safety compliance and participation. These findings replicate Cullen and Hammer's (2007) findings that family-to-work conflict, but not work-to-family conflict, is negatively associated with safety compliance and participation. The replication of these significant findings gives support to macroergonomics' assertion that external forces (i.e., family) can affect the safety of employees. All of the meditating and moderating relationships proposed in this dissertation were not significant. I conducted post hoc analyses to determine other possible significant paths in the model examined. The FSSB dimension of supervisor instrumental support was found to positively affect both safety compliance and participation. Supervisor instrumental support was also found to directly affect work-to-family conflict. Overall FSSB and its subdimensions demonstrated similar patterns in the hypothesized relationships and in additional relationships examined. Numerous implications can be recognized from this dissertation. First, interdisciplinary approaches to safety research are emerging and important in the pursuit of safer work environments. Macroergonomics and I/O psychology have commonalities that lend themselves to a good partnership where researchers can learn from each other and collaborate to advance the study of safety. Second, organizations need to focus on the stressors their employees experience as part of their safety programs, and numerous studies, including this dissertation, have found that family-to-work conflict impacts safety compliance and participation. Future safety research may incorporate macroergonomics, which emphasizes that focusing on one adverse aspect of the system may not be enough to create valuable change if there are other adverse factors still creating demands elsewhere in the system. This will allow for a more comprehensive model that ensures certain aspects of the system are not neglected, which can reduce effectiveness of constructs used to create positive changes.

Le télétravail vient de faire son entrée dans le code du travail par la loi n°2012-387 du 22 mars 2012. Si au regard de la loi, le télétravailleur est considéré comme un salarié à part entière titulaire d’un contrat de travail et subordonné à l’employeur, il accompli cependant ses tâches hors les locaux de l’entreprise en utilisant les technologies de l’information et de la communication. Il en découle que si le travail à distance génère pour le télétravailleur une situation qui se caractérise par une certaine indépendance et une « relative autonomie dans la subordination », il n’en demeure pas moins qu’il reste placé dans une situation de subordination inhérente au contrat de travail. La position singulière du télétravailleur vient ainsi bouleverser le droit des relations individuelles et collectives de travail. Etudier la situation juridique du télétravailleur supposera de se « focaliser » sur la personne en situation de télétravail pour se demander comment sa position singulière peut à la fois le placer dans les liens du salariat, qui suppose l’exercice des droits de tout salarié, mais aussi déterminer les éléments spécifiques de sa situationTelework has been introduced in the Labor Code by the Law N° 2012-387 dated march 22d 2012. By law, the teleworker is considered a full-fledged employee holding an employment contract by which he is subordinate to his employer. Yet, thanks to the use of information and communication technologies he performs his labour outside of the company’s premises. It follows that, even though distance working will afford the teleworker a certain degree of independence and “autonomy within his subordination”, he remains nevertheless placed within the state of subordination characteristic of an employment contract. The teleworker’s peculiar situation therefore disrupts the traditional balance of individual and collective rights afforded to employees. Analysing the legal status of the teleworker will involve “focusing” our attention on the person placed within a telework environment to figure out how this singular situation can place him/her both within the employment relationship, which implies enjoying the rights of traditional employees, while still pinpointing elements that are specific to his situation

Der volle Inhalt der QuelleAnnotation:
Comparative analyses of district-run public schools and charter schools are limited to performance outcomes. There is a dearth of research on how the school-types vary on factors consequential to performance such as school climate. Public-private distinctions, such as in organizational autonomy, value orientations, funding structures, and management practices, could result in school climate dissimilarities between district-run public schools and charter schools.
The aim of this dissertation is to assess the influence organizational factors have on school climate and determine if school-type affects school climate. Student and staff school climate survey data from the Miami-Dade school district were utilized for this dissertation. Structural equation modeling was employed to test theoretical models of students’ and staffs’ perceptions of school climate using data from 2001-2002 through 2015-2016 academic years. Within-between effects panel regression was utilized to test the effect of school-type on school climate constructs over time using data from 2005-2006 through 2015-2016 academic years.
The structural equation results demonstrate that milieu, ecology, culture, and organizational structure influence students’ and staffs’ perceptions of their schools’ climates. Ecology has the strongest association with students’ perceptions of school climate. Job satisfaction, a part of milieu and culture, has the strongest association with staffs’ perceptions of school climate. The results indicate that the theoretical models of school climate employed by this study are sound.
The within-between effects panel regression results demonstrate that characteristics inherent to school-type have a plausible influence on students’ perceptions of school climate, but not for staff. Charter school students rated their school climates more favorably than traditional public schools, but when other factors are controlled, traditional public schools and magnet schools had more favorable ratings. Public-sector values, collective bargaining, and school district oversight may be beneficial to schools’ climates.
This dissertation underscores the impact management and funding structures have on school climate. The author recommends that the school climate concept and evaluations of schools’ organizational practices be incorporated into school improvement policies. The milieu, culture, ecology, and organizational structures of schools should be reviewed when assessing school quality.

Sudden unexplained infant death (SUID) is a sudden death of an infant under 1 year of age that cannot be explained after an investigation or an autopsy. SUID is the leading cause of infant deaths in the United States; SUID is considered a sentinel event to the birth hospital. Birth hospitals are held accountable for education, training, and role modeling of infant safe sleep practices (SSP) to reduce infant sleep-related deaths up to 1 year of age. This educational project was designed to answer the project-focused question of whether the implementation of an evidence-based, safe sleep training program for nurses would improve their knowledge of SSP. Bandura's social cognitive theory and the root cause analysis theory were used to guide the project that provided education on SSP and methods for teaching SSP for 48 nurses who work in a postpartum unit in a large hospital in the northeastern United States. A search of the literature provided the content from the National Institute of Child Health and Human Development for the education program and served the basis for the 15-item multiple-choice test, which was used for the pretest, posttest design project. The test was administered to the nurse participants who ranged in education from associate degree, baccalaureate degree, to master's degrees. The project goal was to increase nurses' knowledge by training and role modeling infant safe sleep environments and to reduce SUIDs. Results of the pretest and posttest evaluation revealed significant improvement in test scores from a pretest M = 72.9 to a posttest M = 90.0 (p <.05). The implications of this project for social change are that each nurse's knowledge and abilities to teach parents and families about SUID prevention strategies improve, sudden infant deaths may decrease in this hospital setting.

All students should be guaranteed a learning environment that is free from all forms of harassment that negatively affect the school climate as well as the learning environment.
The purpose of this quantitative study was to examine the perceptions and attitudes of Sullivan County, Tennessee, K-12 administrators regarding harassment and the associated legal liability. The study also ascertained the attitudes of the administrators pertaining to various forms of student-to-student harassment in their schools, collected data regarding their perceptions of the effectiveness of mandated anti-harassment measures, and examined administrators' attitudes toward the need for more harassment-avoidance training.
The research design was descriptive and used data gathered from a survey instrument developed by the researcher regarding administrators' perceptions and attitudes regarding harassment and the associated legal liability. The survey contained 26 question-items. The study's population consisted of 48 Sullivan County administrators. Data were analyzed using analysis of variance, t test, Pearson's correlation, Tamhane post hoc pairwise comparison, and Tukey post hoc test.
The results of the study indicated that administrators were knowledgeable about the law and legal ramifications regarding student-to-student harassment. The results also showed that middle and high school students needed more harassment-avoidance training than elementary students. No significant differences were found in their perceptions of the current status of harassment based on population, socioeconomic status, or level of the school.
The study offers a valuable insight into administrators' perception and attitudes regarding harassment and the associated legal liability. It also offers a number of recommendations including the need for more harassment-avoidance training to combat this problem for middle and high school students. Effective implementation of bullying prevention programs will need to involve all school stakeholders in order to be successful. The results may be used by school systems to plan for future staff development regarding harassment-avoidance training. Students have a right to feel safe at school as they grow and mature into adulthood. It is the duty of all schools to provide them that safe and secure atmosphere.

This study was designed to examine the benefits of positive school climate and to measure the perceptions of school climate for intermediate grades in a Northeast Tennessee School district. An online school climate survey was used to collect responses from participants in intermediate grades and focused on the 3 major components of school climate: school engagement, school environment, and school safety. Data were collected for 2 consecutive years in 2016-2017 and 2017-2018. Response totals included 1,955 student responses, 116 teacher responses, and 210 parent responses that were analyzed and used for this study. Of the student totals, some students that were in 5th grade in 2016-2017 may have completed the survey again as 6th graders in 2017-2018.
Findings indicated that there were no significant difference in the perceptions of students, parents, and teachers in school climate over a 2-year span for this district. Research indicates there are multiple benefits to a positive school climate, including higher academic achievement, lower chronic absenteeism, and a decrease in discipline referrals.

According to the accident statistics of the Council of the Labor Affairs, the construction has the highest accident rate and almost shares half of the total fatal accidents. One of the causes is that the safety devices have not been well considered about their environmental effects. In view of this, create multiple supervisory and management for construction environment become our top priority. The safety and health inspection items should be included in the construction supervision contract, through the guidance of the contract to implement and strengthen supervision and inspection, and draw up explicit damage penalties. In order to improve the inspection of false situation, the study will create a good management system for construction working site safety. This supervision draft contract will be benefit to clients, supervisors, contractors and their professional engineers, consultant companies, and civil or structure engineers. They can use the guidance of the supervision contract to ensure the safety design and protecting the labors.

Abstract The data of domestic construction industry occupational injure of Occupational Safety and Health Act shows that it accounts a large proportion of the occupational fatalities in construction industry; it is almost half over than any other in the whole industry. One of the reasons for this is that the safety and health needs of the working environment have not been well considered. Therefore, establishing the multiple supervisory and management mechanism is the primary task. Further, safety and health inspection items should be included in construction supervision contracts. The study was actually participated in the implementation of checks on high-risk items of health and safety at the domestic construction workplace. Implementing the checking system of inspector can prevent from occupational accidents, improve the construction environment and the management of safety and protect the lives and property of construction labors. The study can provide the reference of implement for the related domestic inspectors and workers, and also help the safety of construction working and prevent the occupational accidents in the future. Keywords: construction industry, health and safety

The onsite construction guiding provided by the supervision department is the critical success factor for the infrastructure. Beside the scheduling, quality, budget and environmental issues, the supervision department should also make efforts in taking care of the whole construction process including the safety and health during the construction phase. The supervision department handles the construction project in accordance with the requirements of the service contract and the specification agreement. The related regulations should also be referred including: “Government Procurement Act”, “Labor Safety and Health Law” and so on. For the purpose of enhancing the quality of the infrastructure, the Public Construction Commission (PCC) published the “Construction Quality management system for infrastructure” and developed a three-level quality management system for public constructions. The outline of quality and supervision planning was drawn up so as to unify the practice in Taiwan. The Council of Labor Affairs further published the “Labor Safety and Health Regulations for Infrastructure project” to clearly define the responsibilities of both contractor and supervision department respectively. However, it still lacked a complete version of the safety and health management system for infrastructure and a unified standard for the execution of supervision department. Therefore, this paper integrates the regulations mentioned above to establish the four-level quality management system for public constructions. The P-D-C-A” circulation methods referred to “OHSAS 18001 Occupational Safety and Health Management System” is adopted to construct the safety and health management system for supervision department. A prototype of safety and health planning examination outline is further drafted in this paper for entities’, consultant firms’, and contractors’ reference while executing a construction project. It can efficiently reduce the occupational accident and enhance the performance of safety and heath management by using the systemized safety and health examination system.

Doutoramento em Motricidade Humana na especialidade de Ciências da MotricidadeThis dissertation addresses some aspects of child safety grounded on an ecological psychology framework. The investigation of risk affordances was nested in children’s behavior in specific environments, and not merely on a strict dimension-morphology ground. Reaching and climbing skills were analyzed for their relevance to child safety. Adult’s perception of children’s affordances was repeatedly investigated in reaching tasks indicating that adult’s can make reasonable accurate predictions about children’s action limits, but estimation errors and error tendency depend upon the characteristics of the observer, of the child, and of the task. Perceptual experience seems to play an important role in caregivers’ attunement to the information that specifies children’s affordances. One single observation of the child’s action was enough to significantly reduce estimation error, particularly in least accurate perceivers. One chapter replicated a common drowning condition: children trying to retrieve a toy in the water from the swimming pool deck. Different action modes were used but most children sat and fell in while attempting to grasp beyond their reaching limits. Two studies investigated the climbing affordances of safety barriers for children, pointing to an easy and fast crossing of common panel and horizontal bar barriers. Results also indicated that safety devices must consider body dimensions and motor skill. This thesis contributes to a better understanding of children’s behavior in potentially risky environments, as well as an insight into the adults’ perception of children’s action limits.
A presente dissertação aborda aspectos da segurança infantil, tendo como base teórica a psicologia ecológica. Diferentes affordances de risco foram analisadas tendo em conta não só os aspectos morfológicos das crianças, mas também os seus comportamentos em envolvimentos específicos. Foram estudadas as acções de alcançar e trepar devido à sua relevância em termos de segurança infantil. A percepção que os adultos têm das affordances das crianças foi repetidamente investigada em tarefas de alcançabilidade, indicando que os adultos conseguem prever os limites de acção das crianças com uma precisão razoável, e que os erros de estimativa e a tendência de erro dependem de características do observador, da criança e da tarefa. A experiência perceptiva parece ter um papel importante no ajustamento à informação que especifica as affordances das crianças. A observação de crianças a realizar uma única vez uma acção reduz significativamente os erros de estimativa, particularmente quando as estimativas iniciais são pouco precisas. Num dos capítulos replicámos uma situação comum de afogamento: as crianças, na borda da piscina, tentaram alcançar um brinquedo que se encontrava na água. As crianças utilizaram diferentes modos de acção, mas a maioria sentou-se e caiu na água quando o brinquedo estava para além do seu limite de alcançabilidade. A percepção dos pais foi também estudada. Dois estudos analisaram as affordances para as crianças de barreiras de segurança, indicando que as barreiras mais comuns de grades horizontais e de painel são fácil e rapidamente transpostas. Os resultados também indicam que barreiras de protecção adequadas devem ter em conta as dimensões corporais e a habilidade motora das crianças. Esta tese contribui para uma melhor compreensão dos comportamentos das crianças em envolvimentos de risco potencial, assim como para o conhecimento da percepção que os adultos têm dos limites de acção das crianças.

In common with the commercial airlines, Air Force has budgeted billions of dollars annually for the risk-preventing systems of the flight-safety and maintaining the manpower. The new generation aircrafts, such as IDF、F-16、Mirage 2000 and E2T, have replaced the obsolete aircrafts as the major air defense force in recent years. However, because of the difficulty in connecting among the basic level cadre, and generally lack of labors in every work unit which have been ascribed to the 2-stage-Down-Sizing project, even the current flight-safety control system has not been proven to meet the requirement of the new operation condition. The purpose of this study is trying to use the annual Air Force logistic assess program to find out the vulnerability by the analysis from different specialty viewpoints and expecting to survey and submit the performance of the flight safety improvement in different unit and implement and the advice for future development. This study applied the Fuzzy Analytic Hierarchy Process (FAHP) and Multi Criteria Decision-Making (MCDM). In order to solve the question that the traditional AHP theory is lacking in consistency and the human uncertainly deliberating, the fuzzy theory was applied to this research. In this research, the “target composing” has composed of approximately thirty Air Force annual inspectors. In addition, the data for the “assess principal” and the weighted averages method is obtaining from professors and specialists who engaged in the related careers. The safety indices for different Air force units were obtained from the simple additive weight method. The result of this research can be the consultation for the improvement and the evaluation of the future flight-safety in every Air Force unit.

Taiwan is forward to an aging society. With this demographic trend, our medical institutions have started to integrate long-term, nursing, respiratory, dialysis, and postpartum nursing care services with the traditional clinical services provided such as emergency, inpatient and outpatient. According to the Joint Commission of Taiwan (JCT), certified by the International Society for Quality in Health Care Ltd. (ISQua) and a non-government professional accrediting organization, the main causes of fire in the hospitals are improper electricity use of medical equipment, complex wiring system, and the operation knowledge shortage. Without a complete building structure plan, enough disaster prevention knowledge of the employee plus moving difficulty and multiple equipment use of the inpatient always will lead to a great disaster. The medical institution should have a complete disaster prevention plan in order to block the disaster sources with the limited manpower and material resources. In view of this, the national health authorities have included the safety and effectiveness of the medical environments in the complementary auditing item in the annual assessment. The main purpose of this thesis is to analyze the outcome and effectiveness of the assessment form which are formulated by the health authorities to evaluate the safety management of the environmental facilities and equipment of the medical institution by paying field visits of eight sampling local district hospitals and to ensure each of the them has achieved a certain level of effectiveness. In the meantime, the results of this study will be provided to Department of Health, Taipei City Government of Taiwan and expect the Department will update the indicators for supervision and assessment.

ABSTRACT From 1986 to nowadays, the movements of international financial environments had been changing by each nation’s economic development around the world. Because bankruptcy and financial crisis shocked the financial sectors, the Basel committee on banking supervision has declared “the Basel Capital Accord, Basel I” and “the new Basel Capital Accord, Basel II” by sequence, which were constituted in order to improve safety and soundness of the financial system for every country. Each nation also examined and adjusted its mechanism of financial supervision to reach the goal of financial stability and pursue persistent economic growth. This research investigates the relationships on structure of financial supervision, central bank acting as a supervisor and the safety and soundness of financial system. The results show the existence of supervisory arbitrage by adopting multiple supervision in a country. Banks have incentives to seek lower equity/capital ratio, less non-interest revenue, more loans and cause the returns on average equity going down. Further, if the central bank acts as a supervisor, it can prevent banks from taking over-risky activities and becoming insolvent, which can compensate the weakness of adopting multiple supervision. Central bank’s acting as a supervisor would augment banks’ equity/capital ratio, non-interest revenue, security investment rate and decrease outstanding loans, then increase banks’ returns on average assets and returns on average equity. We also find that nations adopting partial consolidated supervision seem to contribute on banks’ performance. By coordinating to central bank’s supervision, their financial systems would be much stable. We conclude that adopting consolidated supervision would be a better choice to improve financial stability when universal banks, financial holding companies and even financial conglomerates boost. Key words: Structure of financial supervision, Central bank acting as a supervisor, Safety and soundness of financial system

The commissioned public construction supervising job currently focuses on analyzing the demerits of the secondary quality assurance, managing the construction progress, clarifying the interface responsibilities, etc. Research information on these and related areas are also available. However, the study on problems related to the supervising job on the construction safety of a commissioned public work is seldom found. In this study, researchers analyzed the possible problems and institutional blind spots that the supervising units were facing when carrying out the safety management through collecting information of projected constructions and sending out questionnaires, aiming to obtain solutions and to propose suggestions to serve as references for managing and supervising the safety of domestic constructions. And, a more agreeable and practicable processing mode is to be generated to result in lowering possibility of accident at work and reducing damage. The results showed that, according to the technical service contract signed with the construction owner, the supervising unit directly supervised the constructor to carry out every detail in the construction contract. The supervising unit was responsible not only for supervising the construction progress, construction quality, construction safety and sanitation, and environmental protection provided by the constructor, but had to watch its own personnel cost on the profit aspect. During the constructing period, the supervising unit truly performed the supervising job on the construction safety and sanitation, not just completing the paper work, was related to the contracted way of payment, mutual right and responsibility, attitude of the project owner, and conflict and compromise of the role responsibility. The number of the safety personnel increases to enhance the efficiency of the supervising and managing if the governmental authorities review and amend the relevant regulations and put the revised in the technical contracts and contract terms of the construction contract for all construction providers to completely authorize the supervising unit to execute the supervising jobs and to truly perform the safety and sanitation managing work.
