Abstract:
Many organisations in the safety-critical domain are service-oriented, fundamentally centred on critical services provided by systems and operators. Increasingly, these services rely on software-intensive systems, e.g. medical health informatics and air traffic control, for improving the different aspects of industrial practice, e.g. enhancing efficiency through automation and safety through smart alarm systems. However, many services are categorised as high risk and as such it is vital to analyse the ways in which the software-based systems can contribute to unintentional harm and potentially compromise safety. This thesis defines an approach to modelling and analysing Service-Oriented Architectures (SOAs) used in the safety-critical domain, with emphasis on identifying and classifying potential hazardous behaviour. The approach also provides a systematic and reusable basis for defining how the safety case for these SOAs can be developed in a modular manner. The approach is tool-supported and is evaluated through two case studies, from the healthcare and oil and gas domains, and industrial review.

Abstract:
The public service ethos (PSE) has spent thirty years - since the advent of New Public Management - in flux. In the late 1990s, partnership working appeared to offer an alternative to NPM, as part of a perceived shift to network governance. What impact has partnership and network governance had on the PSE? This study looked at two case studies of Community Safety Partnerships (CSPs) operating under different local governance conditions. It interviewed public servants within these CSPs on their experiences of partnership working, and perceptions around public service itself. What emerged is a picture of partial network governance, with each case study taking a different approach and yielding different structures and outcomes. While the public servants were professional and committed, they were loyal to their field of work and individual clients. In the recent decades, public interest and consideration of wider societal impact has been removed from everyday working; what remains is a vacuum. The neo-liberal view – that satisfying individual client need creates societal benefit when aggregated – has taken root. PSE is now a partial concept: it remains altruistic but without the core of wider, deeper thinking required. While network governance could ameliorate this trend, the partial and limited implementation of the concept by government means that it hinders PSE as much as it fosters it.

Abstract:
Le contrôle de congestion des canaux sans fil pour la communication véhiculaires (V2X) basée sur IEEE 802.11p ont été conçus pour un seul service de sécurité routière notamment ‘Cooperative Awareness’. Les futurs véhicules connectés seront basés sur plusieurs services V2X, avec un besoin de communication hétérogène, auxquels les mécanismes existants ne répondent pas. Dans cette thèse, on analyse plusieurs protocoles de contrôle de congestion et d’allocation de ressources de canaux, normalisés en Europe pour le déploiement V2X initial. Nous présentons des problèmes liés à l’approche existante, notamment l’utilisation inefficace de la capacité des canaux, la coordination dans la pile protocolaire, la gestion des ressources parmi plusieurs services et l’allocation des ressources pour un besoin asymétrique par les véhicules. On propose des améliorations en tenant compte des exigences des futurs scénarios V2X. Nous montrons les limites de la classification statique des services V2X pour la qualité de service et proposons une classification dynamique. Nous concevons un orchestrateur de ressources afin d'améliorer la coordination dans la pile protocolaire et de répartir dynamiquement la ressource de canal parmi plusieurs services d'un véhicule. En outre, on présente un mécanisme permettant d'orchestrer de manière décentralisée les ressources de canal parmi une distribution mixte de véhicules ayant des exigences d'utilisation de canal diverse, dans un canal de communication congestionné. Les résultats analytiques et résultats par simulations montrent la validité de notre approche qui améliore la performance des applications V2X, par rapport aux protocoles standardisés existants
Wireless channel congestion control and decentralized resource allocation for 802.11p based V2X communication have been widely investigated for a single Cooperative Awareness service, considering mostly homogenous communication requirement per vehicle. Future connected vehicles will be based on multiple V2X services, with heterogenous number of services and communication needs, which existing resource allocation mechanisms does not address. In this thesis, we analyze several decentralized congestion control and channel resource allocation protocols standardized in Europe for initial V2X deployment. We present issues with the existing approach, in particular the inefficient channel capacity utilization, problematic cross layer coordination, inability to balance resources among multiple V2X safety services and distributed resource allocation for asymmetric number of services per vehicle. We propose improvements to the shortcomings, considering the requirements of future V2X scenarios. We demonstrate the limitations of classifying V2X services using static priority for Quality of Service and propose dynamic prioritization. We design a resource orchestrator at the Service Layer to improve cross layer coordination and dynamically distribute the limited channel resource among multiple services of a vehicle. Furthermore, we present a mechanism to decentrally orchestrate channel resource among a mixed distribution of vehicles with diverse channel usage requirements under channel congestion. Analytical and simulation-based results show the validity of our proposed approach, and the V2X application performance improvement it renders, compared to existing standardized protocols

Abstract:
Food service businesses in the United States have experienced millions of dollars in losses caused by foodborne illness outbreaks, which can lead to bankruptcy and business closures. More than 68% of all foodborne illness outbreaks occur in food service establishments. The purpose of this descriptive case study was to explore the strategies leaders of food service establishments use to implement food safety regulations. Force field analysis was the conceptual framework for this study. The population for the study consisted of 3 leaders of food service establishments located in the southeastern region of the United States. Data were collected using semistructured interviews and a review of the business policies and procedures that support compliance with critical food safety regulations. The methodological triangulation approach was used to assist in correlating the interview responses with company policies and procedures during the data analysis process. Yin's 5-step data analysis approach resulted in 3 themes: (a) organizational performance analysis for improvements in food safety, (b) strategies applied to improve food safety, and (c) stability of new strategies for food safety. The key strategies identified included adhering to the guidelines of food code and regulation, conducting employee training and awareness building, and working closely with food safety inspectors. The implications for positive social change include the potential to add knowledge to businesses, employees, and communities on the use of effective food safety strategies to minimize foodborne illnesses. Such results may lead to the improvement of service performance and long-term growth and sustainability of food service establishments.

Abstract:
A thesis submitted in fulfilment of the requirements for the degree of Masters in Communication Science at the University of Zululand, South Africa, 2012.
Advances in electronic service technology have created great opportunities as well as threats to organizations in various business and services sectors. As such businesses, either willingly or reluctantly, are increasingly embracing the Internet as distribution channel in order to remain competitive or gain market share. With particular reference to e-services, absence of accurate information on factors that have influenced user’s behaviour to adopt or use e-services could mislead an organization into adopting unhelpful solutions as it strives to accelerate the implementation of e-services. The study is undertaken by a student who lives in the heart of a rural community in South Africa and also attends a University which is based in a rural settlement. This study, based on the perceptions of rural communities on the safety of e-commerce transactions, investigates factors that influence adoption and usage of e-service, especially, in eNkandla rural communities. Factors were empirically tested against data collected from four hundred participants using survey questionnaires. Perceived complexity was found to be the most significantly related factor affecting e-service adoption in rural communities of eNkandla, followed in turn by privacy and compatibility. Quality of the Internet and its relative advantage also had a notable effect on e-service usage and adoption in eNkandla rural communities.

Abstract:
Les concepts d’architecture orientée service (SOA) ainsi que tout une panoplie de technologies «en tant que service» (XaaS) sont utilisés quasiment partout de nos jours, et l’organisation optimisée d’activités synchronisées devient un défi important. Dans le but de proposer à l’utilisateur final un service sécuritaire et fiable sans compromettre la qualité, les questions concernant la vérification et la validation des compositions des services deviennent d’un grand intérêt tant théorique que pratique. Dans les autres travaux traitant du sujet, de nombreux modèles et techniques sont proposés, mais la plupart mettent l’accent sur les aspects fonctionnels ou non-fonctionnels pris séparément, alors que l’intégration de ces paramètres en un modèle formel unifié reste un problème qui doit être résolu – ce qui est devenu par conséquent un des objectifs fondamentaux de cette thèse. Dans notre travail, nous réfléchissons aux problèmes de la vérification et de l’optimisation des compositions des services web. Tout ceci est étudié dans l’optique de la fonctionnalité des systèmes, de leur qualité et de la sécurité des compositions. Il a été prouvé que les modèles à états finis sont utiles à des fins de tests et de vérification, de même que pour le contrôle qualité à chaque étape du développement du service. C’est pour cette raison que nous proposons d’utiliser le modèle de machine temporisée à états finis (TFSM) pour intégrer une description fonctionnelle du service avec les paramètres de sécurité et de qualité liées au temps. L’extension du modèle permettra alors d’interpréter adéquatement le non-déterminisme significatif causé par un manque d’observabilité ou/et de contrôle sur les services tiers. Dans le but d’optimiser les compositions des systèmes, nous proposons une méthode pour dériver la solution la plus globale contenant tous les composants autorisés pour la mise en œuvre du service, basée sur la résolution de l’équation parallèle du TFSM. Ensuite, les techniques pour extraire des solutions restreintes avec les propriétés requises (paramètres de temps minimisé/maximisé, interblocages actifs ou passifs de sécurité, similarité avec le composant d’origine donné, etc.) ont été proposées. Dans le cas où les spécifications d’un service composite consistent en un ensemble d’exigences fonctionnelles, éventuellement renforcées par des exigences de qualité, nous proposons une technique de minimisation de l’ensemble, dans le respect du composant à optimiser. L’application des résultats obtenus à la découverte et à la mise en place de composants plus efficaces, ainsi que l’extension du modèle à des modes de communication plus complexes font partie des sujets possibles pour des études futures
Service-oriented architecture (SOA) together with a family of Everything-as-a-Service (XaaS) concepts nowadays are used almost everywhere, and the proper organization of collaborative activities becomes an important challenge. With the goal of bringing to the end-user safe and reliable service with the guaranteed level of quality, issues of service compositions verification and validation become of high practical and theoretical interest. In the related works, numerous models and techniques are proposed, but mostly focused on functional and non-functional issues in isolation, while integration of these parameters within unified formal framework still remains a problem to be solved – and therefore became one of the core objectives of this thesis. In our work, we address the problems of web service composition verification and optimization with respect to functional, quality and safety properties of the composition. Finite state models are proven to be useful for testing and verification purposes as well as for service quality evaluation at each step of service development. Therefore, we propose to use the model of Finite State Machine with Timeouts (TFSM) for integrating functional service description with time-related quality and safety parameters, and derive the extension of the model in order to adequately inherit significant nondeterminism due to the lack of observability and control over third-party component services. For the purpose of component optimization in the composition, we propose a method for deriving the largest solution containing all allowed component service implementations, based on solving TFSM parallel equation. Further, techniques for extracting restricted solutions with required properties (minimized/maximized time parameters, deadlock- and livelock-safety, similarity to the initially given component, etc.) have been proposed. In cases when the specification of a composite service is provided as a set of functional requirements, possibly, augmented with quality requirements, we propose a technique to minimize this set with respect to the component under optimization. Application of the obtained results for more efficient candidate component services discovery and binding, alongside with extending the framework for more complex distributed modes of communications, are among the topics for the future work

Abstract:
When project sites consist of substandard design elements according to standards set by the Federal Highway Administration (FHWA), design exceptions are implemented. The goal of this thesis is to analyze a sample set of 18 design exceptions taken from a total of 467 design exceptions approved in Georgia from 1995 – 2012. Crash data were obtained at the locations of each of these design exceptions three years before the let date and three years after the construction end date. To compensate for causal factors other than the design exception on the roadway, similar information from a range of control sites were also obtained. These control sites consisted of projects without design exceptions that occurred within the same time constraints as the design exception projects, were of the same work type, and were either located on the same route or within the same district. The potential safety impacts of the design exceptions were evaluated by comparing the before and after crash rates of projects before and after crash rates at these control sites Based on these data, no statistically significant relationship between the existence of a design exception and crash rates was identified. The sample set in this study was too small and the number of crashes found at both projects with design exceptions and control sites without design exceptions was too low to perform a significant Empirical Bayesian (EB) analysis. When additional data is available, an EB before and after analysis is recommended to compensate for any potential regression to the mean bias.

Abstract:
Due to the rapid development in electronics and radio communication systems, modern technologies are implemented to improve the safety and security of workplaces in order to save field service engineers lives and their health. In this thesis, an automated safety suit was implemented with integrated sensors for monitoring the safety of field service engineers. The basic idea of the prototype is to ensure safety for the field service engineers who are working in adverse environmental conditions. This safety suit includes embedded devices which can communicate with mobile devices and by means of that provides aid for the people working in several fields such as confined spaces, high altitudes etc. In this prototype, a different type of sensors are proposed for monitoring environmental and health conditions like temperature, CO gas levels, relative humidity, body temperature and heartbeat. A mobile application is proposed to monitor and control the automated safety suit, which also identifies the environmental changes and provide prompt alerts to the user. Keeping the usage of automated safety suit in mind, the system is designed in a user friendly manner and all the key elements are considered and implemented accordingly for the requirements of service engineers who are working in confined spaces and hazardous places.

Full text
Abstract:
Increasingly stringent equipment performance and reliability requirements are being specified to the aerospace industry by aircraft manufacturers, driven by the expectations of both certification authorities and operators. The reality is that aircraft system and equipment reliability in service can fail to meet the design expectations. This thesis details the problem areas within the current analysis process, describing the procedures currently in use and showing what can go wrong. It goes on to propose action that can be taken to ensure safety levels are maintained and details a new approach that is unique to this thesis. The author has devised a new System Safety Compliance Model (SSCM) for ensuring that aircraft system safety standards can be better maintained. Evolved from his earlier highly successful database system at TRW Lucas Aerospace, SSCM will be: - Demonstrably cost effective - A step change in process capability, offering "something new" - Instantly accessible at shop floor level to everyone in the business - Easy to use and as automated as possible to minimise staff training requirement - Capable of performing instant re-assessment of safety performance down to system level and including consideration of a variety of operating environments and conditions - The industry standard repository of component reliability data - "Centrally" owned by a world-wide recognised industry body SSCM is the first system to operate in such a way, and will ensure that the original system safety analysis performed at the design stage, is continually assessed for accuracy throughout its in-service life. If the new methods detailed in this thesis are adopted and acted upon, there is a high probability of a reduction in the risk of aircraft systematic failure in service, leading to increased safety in aviation. The model can be equally applied to other areas of transportations uch as railways.

Abstract:
The discourse of commercial aviation flight attendants has historically received no sociolinguistic attention. To address this gap, this thesis explores how flight attendants use language in workplace-related contexts to construct their professional identity and community. I draw on interactional sociolinguistics (Goffman 1981; Schiffrin 1994; Tannen 1993) and sociological research (Van Maanen and Barley 1984; Williams 1986; Marschall 2002) to address how flight attendants use language to orient to occupationally related knowledge and practices which contribute to the discursive construction of community. Data come from two sources: 1) A corpus of 150 textual incident reports submitted by flight attendants to a US government agency which include summaries and proposed causes of the incidents in flight attendants’ own words. 2) A corpus of 105 unique discussion threads containing 4,043 posts to a website hosting several discussion forums aimed primarily at flight attendants. The forums are not affiliated with either government bodies or airline employers and are a virtual space for flight attendants to discuss aspects of their job away from occupational demands. Following Bucholtz and Hall (2004), I show how identity is contextually related and situationally constructed, and emerges from discursive orientations to professional practice, indexicality, ideology, and performance. Moreover, there are certain intersubjective relationships embedded in the discourse which emerge from and add detail to the situational identity constructed through flight attendant discourse. Indexical stances and ideologies which are grounded in institutional training frame and are heightened in the discursive performances of the reports and forum posts. These ideologies motivate and enhance the existing institutional, physical, and sociocultural divisions between flight attendants and pilots, which may have consequences for intercrew cohesion in emergency situations.

Full text
Abstract:
This research identifies realistic timelines for human survivability during accidental dwelling fires (ADF). It also establishes a time window within which the fire service is likely to affect a rescue of the occupants from ADFs. Through a comparison of these two timelines, the likelihood that the fire service will rescue an occupant before they receive a fatal dose of heat and/or smoke (asphyxiant gases) is established. The dependence of fire service intervention times is also assessed in the context of increasing intervention times resulting from cuts to fire authority budgets. The results show that an increase in the time taken to affect a rescue will lead to an increase in the number of fatalities and the severity of injuries which occur when the occupants of a dwelling become trapped by (or are otherwise unable to escape from) fire within the property. Around 80% of all fire deaths and injuries in Great Britain occur in dwellings. This study analyses national and local fire statistics to identify the typical fire situations and common circumstances which lead to fire deaths and injuries. This statistical analysis has been used to inform the carrying out of thirteen large-scale fire experiments. Asphyxiant gas concentrations and compartment temperatures were gathered during these experiments, in order to establish human survival times resulting from the adverse effects of exposure to these. Statistics have also been analysed and a methodology developed to establish fire service intervention times. Establishing survival times on the basis of an analysis of national statistics constitutes new work within the field of community fire safety. In addition, the author is in a preferential position to establish realistic times for fire service interventions, and there is no evidence that these timelines have previously been developed to this extent or compared to timelines for occupant survival. The findings of this research should be considered by fire authorities as they make important decisions for the development of local fire service resourcing activities in continuing times of austerity.

Abstract:

The topic of the study was burnout amongst volunteer emergency service personnel in a Northeastern state. An understanding of the role burnout plays in emergency service professionals exists in the literature; however, the current research expanded the understanding by focusing on volunteers. Years of experience and resilience were studied to determine if a relationship exists with burnout. Data analysis consisted of multiple regression analyses conducted for each subscale of the Maslach Burnout Inventory – Human Services Survey (emotional exhaustion, depersonalization, and personal achievement) (Maslach, Jackson & Leiter, 1996). Results concluded that resilience, as measured by the Resilience Scale (Wagnild & Young, 1993), was found to be statistically significant in its ability to predict emotional exhaustion and personal achievement, at the p < .05 significance level. Resilience significantly predicted emotional exhaustion subscale scores of the Maslach Burnout Inventory – Human Services Survey, β= -.25, t(82) = -4.36, p < .001. Resilience and length of service when considered together also explained a significant proportion of variance in emotional exhaustion scores R2 = .92, F(2,82) = 9.65, p < .001. Resilience significantly predicted the personal accomplishment subscale, β = .21, t(82) = 5.19 p < .001. Resilience and length of service when considered together also explained a significant portion of the variance in personal exhaustion scores, R2 = .25, F(2,82) = 13.91, p < .001. Results concluded that resilience was not a statistically significant predictor of the depersonalization subscale; β = - .07, t(82) = -1.72, p = .090. Length of service was not considered to be a statistically significant predictor for the subscales (emotional exhaustion, depersonalization, and personal achievement) at the .05 alpha level. Resilience and length of service when considered together did not explain a significant portion of the variance in depersonalization scores; R2 = .04, F(2, 82) =1.90, p=.157. The regression analysis demonstrated that there was a low correlation between predictor variables of resilience, as measured by The Resilience Scale and length of service, r = .123. A stepwise regression analysis was also conducted and confirmed that the predictor variable of resilience held a greater control over the outcome variables in each regression analysis with a significant outcome. Study implications centered around a recognition that volunteer emergency service personnel can be affected by the work they perform in many similar ways as their paid counterparts. Further research is recommended to increase understanding of the relationship that other demographics and factors may play in the depletion of resilience and development of burnout in related professionals.

Full text
Abstract:
This thesis describes the development, application and evaluation of an OHS measurement tool incorporating positive performance indicators to measure OHS performance in Australia Post, a large multi-site postal organisation. Positive Performance Indicators (PPIs) are identified as systematically implemented measures of the management processes initiated to achieve strategic goals. A literature review indicated that there was widespread support for the use of PPIs to measure OHS performance, with proponents advocating their use to monitor and promote implementation of target OHS strategies, and to evaluate the effectiveness of these strategies by using PPIs in conjunction with outcome indicators. Despite this widespread support, there was little practical guidance published on the development or application of PPIs, nor was there empirical evidence validating the claims of advocates. A series of research projects was undertaken to firstly develop - then evaluate - a set of OHS self-assessment tools incorporating PPIs. These projects comprised: review of the Australia Post OHS strategic plan, as the basis for the development of PPIs to measure that plan; development of a set of paper-based self-assessment tools incorporating quantitative OHS PPIs to measure the local implementation of the OHS strategic plan; quasi-experimental pilot study of the use of the OHS PPI self-assessment tools by Postal Managers, to investigate the reliability and effectiveness of the OHS PPI process in monitoring and driving conformance of OHS management processes; experimental study of the use of the OHS PPI self-assessment tools by Postal Delivery Facility Managers, to validate and extend the findings of the pilot study; development of a web-based software application to facilitate OHS PPI data collection and reporting; and, the use of correlation statistics to study the relationship of OHS PPIs with OHS outcome measures, and to assess their role in evaluating the effectiveness of specific OHS strategies. The studies demonstrated that the OHS PPI self-assessment tool could be effectively used by local facility managers to assess and report their implementation of the OHS strategic plan. In addition, the OHS PPI self-assessment process proved to strongly improve the local implementation of those OHS management processes measured. The study further showed that the consistent attention to OHS management processes driven by the OHS PPI measurement process assisted in the achievement of impressive OHS outcome improvements. However, the study showed that the use of correlation statistics to link OHS PPIs with outcome measures to evaluate the effectiveness of OHS management strategies has only limited value. Limitations in both the OHS PPI and outcome measurement data and in the correlation statistics restrict the extent to which findings can be interpreted or that conclusive judgements concerning the effectiveness of strategies can be drawn. The thesis concludes with an account of Australia Post's experiences in integrating OHS PPIs into its OHS management system.

Abstract:
The Virginia Tech Center for Wireless Telecommunicationsâ (CWT) Public Safety Cognitive Radio (PSCR) addresses the radio interoperability issues that plague many of the existing public safety radios â disparate frequency bands, incompatible modulation schemes and lack of active channel detection features. The PSCR allows the operator to scan for active channels, classify the detected channels, connect to any of the recognized waveforms and begin analog audio communication as well as bridge two incompatible waveforms together. The PSCR, although very useful, unfortunately is not portable enough to be used by public safety officials. The power requirement, processing requirement and equipment is respectively large, hungry and bulky. In this thesis, a possible solution to the portability problem is addressed by installing the PSCR in a public safety vehicle and using a Personal Digital Assistant (PDA) for remote access. The PDA allows the user to remotely scan, classify, talk, and bridge waveforms similar in operation to the PSCR. An ergonomically designed interface masks the channel and modulation selection procedure. This architecture can be extended to offer service to any remotely connected device. In the second part of this thesis, the concept of remote access is extended to a wide-area wireless public safety network. A public safety network consisting of heterogeneous devices is proposed utilizing a small number of backbone nodes. The major research focus of this section is the algorithm for distributing services across the network. Service discovery is optimized to reduce the overhead of service messages and multiple service distribution techniques are utilized depending on the location of the services. Simulation is performed to evaluate the performance of the service discovery protocol in terms of overhead, dissemination time and scalability. The proposed protocol is determined to be superior to the competition in the overhead and scalability tests.

Abstract:
The perpetual rise in the number of emergencies around the globe has indicated a requirement for ubiquitous public safety services. Unfortunately, traditional public safety networks, being dependent on land mobile radio systems, fail to enable such services in all management stages of an emergency, namely, mitigation, preparedness, response and recovery. While infrastructure-based networks such as wireless local area networks (WLANs), realizing machine-to machine (M2M) networks, can enable such services with higher ubiquity, they only offer localized ubiquity. However, the aforementioned challenges can be mitigated by establishing infrastructure-less networks such as mobile ad hoc networks (MANETs) through M2M communication between hand-held mobile devices closely attached to emergency-affected users. Nevertheless, the inherited challenges of MANETs, for instance, traffic congestion, mobility and service accessibility must be addressed in emergency environments to achieve ubiquitous public safety services in all stages of an emergency. Consequently, the first objective of this thesis is to introduce the idea of MANETs as enablers of public safety services in scenarios when the traditional public safety and the WLAN-based M2M networks are neither available nor effective to enable such services. Another objective of the thesis is to propose M2M-based solutions, integrating emergency-affected user behavior, to overcome inherited issues in MANETs to enable ubiquitous public safety services in all stages of emergency management. The above goals have been achieved in this thesis through the unique developments of a semantic traffic-aware framework, post-emergency mobility model, prediction-based service replication middleware and context-aware service selection middleware. Finally, through extensive simulations, this thesis shows that the developed M2M-based solutions can effectively enable ubiquitous public safety services in MANETs for complete emergency management.

Abstract:
Safety is the main concern of the aviation industry. All Air Navigation Service Providers must have a Safety Management System (SMS) which states how safety is handled, promoted and prioritized. By developing Key Performance indicators (KPIs), it is possible to quantify the effectiveness of a SMS, discover potential flaws and improvement measures. This thesis identifies principles behind the SMS, the development of KPIs and suggest potential KPIs for the Swedish air navigation service provider LFVs’ SMS. A literature study was performed and organisation specific documents were analysed to develop potential KPIs within the areas timely compliance with international obligations, competency and adoption and sharing of best practices based on an EASA questionnaire. This work presents a set of 27 performance indicators and recommends 6 as potential KPIs for the three areas together. The KPIs are developed specifically for LFV but could be applicable for other organisations with similar SMS structure and processes. They should be analysed within the organisation and, potentially, have thresholds set before implementation.

Abstract:
Public service announcements (PSA) have been utilized successfully to promote the health behaviors to the public. In spite that Hong Kong government keep increasing the budget of PSA (admanGo, 2015;2016), the effectiveness of PSA is seldom measured. Previous studies focus on testing the discourses, contents, and public's interpretations of PSA (Chan and Huang, 2015; Chan & Chang, 2013; Wong, 2006). Little research tries to explore the design and effectiveness of PSA. Besides, Hong Kong is facing a serious road safety issue due to the rapid development of the economy. And the convenient use of mobile phones causes the public pays less attention to road safety issue. According to the annual report of road safety council (2015), "inattentively" is the primary contributory factor in road accidents both from driver perspective and passenger perspective. A study was designed to investigate the public attitudes and behavior related to road safety and their responses to public service announcements using narrative or fear appeals. Two main theories were utilized to create the theoretical framework for this study: Regulatory fit theory and the Theory of planned behavior. The hedonic principle plays a role in the basic function of RFT and TPB. Both of them aim to change people's behavioral intentions and concerns that people approach pleasure and avoid pain. The core principle in RFT is to examine people's approach and avoidance mechanisms based on the two regulatory focus systems. On the other hand, TPB emphasizes that people's intentions are performed based on the chronic perceptions of the positive or negative outcomes of the recommended behaviors. Once people think the recommended behaviors are favorable, they are more likely to engage, which matches the principle of pleasant and pain from RFT. This study investigates the impact of either focusing on promotion or prevention in the Regulatory fit theory along with fear appeal, which could modify the variables in Theory of planned behavior, by taking road safety as a context. The purpose of this study is to explore whether Regulatory fit theory with fear framing will have merit under several conditions that may influence individuals' emotional responses, behavioral intentions, and information processing. Survey methodology was adopted. A model incorporating variables in RFT and TPB was proposed. A structured questionnaire was designed to include the key constructs in the RFT and TPB. Altogether 523 responses were collected from 30 November 2017 to 24 December 2017, including 106 respondents from the questionnaire in paper form and 481 from the online platform, in Hong Kong and Mainland China. Four types of stimuli were designed to examine the model. Empirical data of this study confirms the high influence of predictors including attitude towards behavior, perceived behavioral control, and subjective norms to predict behavior intention. In particular, subjective norms are the highest-level predictor. About the self-regulatory fit, promotion focus predicts more than prevention focus on health communication. What's more, the results showed that perceived relevance is a key factor when people make decisions about a health-related behavior. This study theoretically attempts to extend Regulatory fit theory by adding fear as the emotional variable that tests whether fear is fit/unfit for an individual's regulatory focus, especially in the behavioral health context, which can help practitioners better understand the use of fear appeal along with Regulatory fit theory and how it impacts individuals' health behaviors. Practically, this study explores the theory-driven communication strategy for practitioners. Fear appeal is one of the most common tactics in health communication campaigns, but there is a lack of research to compare the practical impact of fear appeal. For instance, most practitioners prefer to adopt fear appeal rather than emotional appeals or narrative appeals in health promotions, but few empirical studies have verified the benefits of fear appeal from a theory-based perspective. Furthermore, this study seeks to answer some questions in daily health communication in daily life by applying the Regulatory fit theory, such as how different focus-oriented people understand the fear appeals in health messages. The findings of this study will explore some effective message strategies for health communications and marketing practitioners.

Abstract:

Although the term maritime safety is widely used in the maritime domain, there is no exact definition of what is included in it. This thesis is an explorative study with focus on the Vessel Traffic Service domain. VTS operators were interviewed and observed to gain insights in how maritime safety is constructed from the perspective of an operator. Further, definitions of maritime safety by central organizations in the maritime domain have been studied through a literature study and several interviews.

The results of the study indicate that there is no common definition of the term maritime safety. The organizations generally identify maritime safety as an overall goal or an umbrella term for measures such as traffic separation schemes or fairway design etc. In contrast to this, the analysis of the data obtained indicates that VTS operators define maritime safety as a context-dependent condition which is shaped by their own action.

It is concluded that there is a gap between the central actors’ and the VTS operators’ understanding and definition of maritime safety. To increase the overall safety in the maritime domain, there is the need to overcome this gap through constructing common values, norms and identities. Instead of having several definitions of maritime safety, there should be one definition which can capture the fact of safety being a dynamic condition which is shaped by the enactment of reliability through, in this case, the VTS operators.

Finally, the VTS as service to the maritime community should be seen as the subject in the construction and promotion of maritime safety, not as just an object.

Abstract:
BACKGROUND: Formalized risk management (RM) is an internationally accepted process for reducing hazards in the workplace, with defined steps including hazard scoping, risk assessment, and implementation of controls, all within an iterative process. While required for all industry in the European Union and widely used elsewhere, the United States maintains a compliance-based regulatory structure, rather than one based on systematic, risk-based methodologies. Firefighting is a hazardous profession, with high injury, illness, and fatality rates compared with other occupations, and implementation of RM programs has the potential to greatly improve firefighter safety and health; however, no descriptions of RM implementation are in the peer-reviewed literature for the North American fire service. METHODS: In this paper we describe the steps used to design and implement the RM process in a moderately-sized fire department, with particular focus on prioritizing and managing injury hazards during patient transport, fireground, and physical exercise procedures. Hazard scoping and formalized risk assessments are described, in addition to the identification of participatory-led injury control strategies. Process evaluation methods were conducted to primarily assess the feasibility of voluntarily instituting the RM approach within the fire service setting. RESULTS: The RM process was well accepted by the fire department and led to development of 45 hazard specific-interventions. Qualitative data documenting the implementation of the RM process revealed that participants emphasized the: value of the RM process, especially the participatory bottom-up approach; usefulness of the RM process for breaking down tasks to identify potential risks; and potential of RM for reducing firefighter injury. CONCLUSIONS: As implemented, this risk-based approach used to identify and manage occupational hazards and risks was successful and is deemed feasible for U.S. (and other) fire services. While several barriers and challenges do exist in the implementation of any intervention such as this, recommendations for adopting the process are provided. Additional work will be performed to determine the effectiveness of select controls strategies that were implemented; however participants throughout the organizational structure perceived the RM process to be of high utility while researchers also found the process improved the awareness and engagement in actively enhancing worker safety and health.

Folklorama in Winnipeg, Manitoba, Canada is a 14-day temporary food service event that explores the many different cultural realms of food, food preparation, and entertainment. The ethnic nature and diversity of foods prepared within each pavilion presents a unique problem for food inspectors as each culture prepares food in their own very unique way. In 2010, the Russian pavilion at Folklorama was implicated in a foodborne outbreak of E.coli O157 causing 37 illnesses and 18 hospitalizations. Both the Department of Health and Folklorama Board of Directors realized a need for implementation of a food safety delivery program that would be more effective than a simple 2-hour food safety course delivered via PowerPoint slides. Until 2011, the 2-hour food safety course delivered to event co-ordinators and food operators for Folklorama pavilions was not mandatory. The course is now mandatory in 2011 for all Folklorama pavilions. Five randomly chosen pavilions were trained on-site, in their work environment, focusing on critical control points specific to their menu. A control group (five pavilions) did not receive on-site food safety training. Critical infractions noted on standardized food inspection reports were assessed. Results of the current study suggest no statistically significant difference in food inspection scores between the trained group and control group. Results imply that the 2-hour food safety course delivered via slides was sufficient to pass public health inspections.

The state of fire service substance-testing policy nationwide, and what it should be, is the subject of this project. This thesis analyzed 12 substance-testing policies from fire departments across the country. The project looked at the language fire departments were using to convey the intent, process, and consequences of their policy. Common themes emerged as each policy was examined. However, upon closer examination, more inconsistency was found than uniformity. Differences ranged from policy purposes to prevailing guidance to types of substances tested for, threshold levels, and employee treatment, with the greatest difference found in the terminology. As a result of the analysis, this thesis identifies best practices and required components of a standardized national substance-testing policy, and asserts that such a national model should be implemented.

Abstract:
The research aim was to evaluate whether it is possible to reliably measure change in health and safety performance when a formal health and safety intervention is introduced to the UK healthcare sector.  The research methodology and design was informed by a review of relevant literature.  Field study data was generated using a six-point design.  This included: use of a before-and-after (longitudinal) design, use of comparison groups; use of an intervention that was of interest to participating NHS Trusts, use of a participative style which involved the participating Trusts; use of multiple measurement methods and multiple indicators of effectiveness. Seven NHS Trusts participated; two of which were a control group.  The intervention was health and safety management workbook, introduced only to the test group.  Evaluation of the impact of the workbook on health and safety performance involved two identical phases, the second approximately twelve months after the first.  Each phase consisted of a staff opinion questionnaire survey, based on previously validated work; and a new Health and Safety Executive (HSE) methodology involving management root cause analysis plus cost estimations of incident data. There was wide variation in the numbers of incidents reported within each Trust, although the mean difference between phases was not significant (P<0.1).  There was no significant difference between the test and control Trusts (P=0.05).  Incident rates were in broad agreement with official HSC data, so far as fatal/major injury rates wee concerned, although there was less agreement for minor incidents. These results suggested that Trust reporting culture may be linked to overall reporting rates but that captured incidents, (which met the project inclusion criteria and therefore represented more serious incidents), were independent of reporting rate, size and type of Trust.  The use of incident reporting rates as benchmarking indicators should therefore be used with caution until further work can be carried out to clarify the nature and scope of their limitations.  There is also a need to clarify to relationship between major and minor incidents and whether they share similar root causes.  This would help to establish whether recording only the more serious incidents with selective root cause analysis would be more cost effective than the processing and analysis of large numbers of incident reports.

Abstract:
Detta examensarbete är ett projekt inom metodiken tjänstedesign som utforskar ekosystemet av aktörer i kedjan av trygghetslarm för äldre i Malmö Kommun. Syftet med detta examensarbete var att utforma förslag till tjänstekoncept som uppfyller de behov som användaren av trygghetslarmet upplever. Detta med hänsyn till alla involverade aktörer inom ekosystemet i kedjan av trygghetslarm för äldre. Dessa skulle utformas genom att identifiera de främsta problemområdena, samt relaterade primära behov, som uppstår i relationerna mellan de olika involverade aktörerna i den nuvarande tjänsten. Denna kvalitativa forskningsmetod har främst använts för att, utifrån insikter insamlade genom kundinteraktioner, designa om och utveckla en användarcentrerad tjänst. Parallellt har den tillika använts för att skapa en hållbar och konkurrenskraftig tjänst gentemot tjänsteleverantören. Denna metod utgår från en iterativ process där varje iteration består av fyra steg: kundinteraktioner, kundinsikter, idégenerering och triggermaterial. De kundinteraktioner som genomfördes genererade insikter som analyserades och användes för att generera konceptidéer som iterativt utvecklades under fyra iterationer till två slutkoncept.  Utifrån de identifierade problemområdena, med relaterade primära behov, identifierades två behovsgrupper; Ensamanvändare och Primäranvändare. Med hänsyn till de primära behoven för behovsgruppen Ensamanvändare utformades ett tjänstekoncept som benämndes Äldreguiden. För behovsgruppen Primäranvändare utformades riktlinjer för utveckling av det befintliga systemet som benämndes Design guidelines för Information. Slutsatsen av examensarbetet är att det framtagna förslaget för tjänstekoncept samt de utformade riktlinjerna ses ha potential att tillmötesgå de analyserade primära behov som de två identifierade behovsgrupperna upplevde.
This Master’s degree project is a project in the methodology of Service Design that explores the ecosystem of actors within the chain of security alarms for the elderly in Malmö Municipality. The purpose of this degree project was to draft proposals for service concepts that meet the needs of the security alarm user. This takes into account all involved actors in the ecosystem in the chain of security alarms for the elderly. These proposals would be designed by identifying the main problem areas, as well as related primary needs arising in the relationships between the various involved actors in the current service. This qualitative research method has been used primarily to design and develop a user-centered service based on insights collected through customer interactions. In parallel, it has also been used to create a sustainable and competitive service towards the service provider. This method is based on an iterative process where each iteration consists of four steps: customer interactions, customer insights, idea generation and triggers. The customer interactions conducted generated insights that were analyzed and used to generate concept ideas that were developed iteratively during four iterations into two final concepts. Based on the identified problem areas, with related primary needs, two needs groups were identified; Ensamanvändaren and Primäranvändaren. Considering the primary needs of the need group Ensamanvändaren, a service concept was developed, called Äldreguiden. For the Primäranvändaren need group, guidelines were developed for the development of the existing system, called Design guidelines för Information. The conclusion of the thesis is that the draft proposal for service concepts as well as the guidelines developed are seen as having the potential to meet the primary needs identified for the two analyzed needs groups.

Thesis (MTech (Consumer Science: Food and Nutrition))--Cape Peninsula University of Technology, 2004
Concems have been voiced regarding the food practices and dietary intake of students since residences changed from a catered to a self-catering food provision system. In this study, the purchasing, storage, food preparation practices and dietary intake of female students living in self-catering residences at the Cape Technikon in Cape Town, South Africa, were investigated. A sample of 60 students, representative of the female students living in self-catering residences, participated. A structured interview, together with direct observation, using an observational checklist, was used to determine whether food practices complied with food safety guidelines. As self-reported and actual behaviour may differ, the reported food safety behaviour was compared with the observed behaviour. The mean food and beverage intakes were determined using two 24-hour dietary recalls covering a week and weekend day. Intakes were compared with the recommendations of the Daily Food Guide and the South African Food-Based Dietary Guidelines. Nutrient intakes were analysed using dietary analysis software. Nutrient intakes were compared with the Dietary Reference Intakes for their gender and age grouping. Intakes of S 67% of the Recommended Dietary Allowance/Adequate Intakes or below were deemed as inadequate. The weight status of the students was also determined and compared to the health maintenance Body Mass Index range of 20 to 25 kg/m2 . Results indicated that some, but not all food safety guidelines were followed. Both positive and negative practices were reported and observed.

Abstract:
The significant growth in the South African tourism industry in recent years has placed much focus on the hospitality sector in the country. The hospitably sector performs a vital role in the South African economy, as is the case globally, to provide accommodation to international and national tourists. Guest houses in particular have become one of the fastest growing components of the South African tourism industry. However, operating a guest house is not merely providing a bed, shower and breakfast facility for which a client pays and hopefully returns again in future. Rather, it involves significantly more than providing physical amenities. Not only does a potential entrepreneur require a suitable facility in a well-positioned location, but guest house owners and management must adhere to various strenuous safety, security and service measures, as well as municipal by-laws, in a tough and ever-changing business environment. The central theme and the main objective of this study was to investigate the safety, security, service and legal measures that need to be adhered for the successful management of a guest house in the Nelson Mandela Bay Metro. Together with an outline of the various steps required to start a guest house, a sub-objective was to compile a guest house manual that can be used by new and existing guest house owners and managers to improve their business. The target group was divided into two sections, namely guest house owners and managers on the one hand, and guest house clients on the other - hence two separate questionnaires were developed and used as measuring instrument for the empirical study. The results revealed that clients in the Metro are in general satisfied with the service they receive and safety they experience when staying in guest houses in the Metro. The premises are mostly neat and clean, the towels and bedding are regularly replaced and clean, while the parking bays are sufficient and safe, staff members friendly and approachable, and bookings are done promptly. Over and above the different by-laws to observe, it is the duty of owners and management to provide clients with a safe, secure environment with excellent service, and with sufficient lighting at the entrances, parking and reception areas. All staircases should be steady and iv non-slip, and swimming pools should have secured fencing around and/ or should be covered by safety nets. Staff should follow the correct procedures in emergencies, while concerted efforts should be made to adapt guest houses for the specific needs of disabled and elderly clients. To prevent the outbreak of food poisoning, and to ensure personal and kitchen hygiene, as well as the correct storing of food, are other important responsibilities of owners and management. Therefore, for a guest house to be managed successfully, the owners and management must take into consideration the required safety, security, service and legal measures.

Abstract:
The use of temporary staff in healthcare presents a management challenge. There is a case for minimising their use to reduce the risks associated with their limited familiarity with the context and knowledge of protocols. However, staff shortages can negatively affect patient outcomes. Consequently, temporary staff are required but need to be carefully managed. This thesis uses the analytic framework of the psychological contract to explore the previously neglected management of the employment relationship with temporary staff. The empirical research consisted of two studies. The first explored the management of temporary staff in Emergency Departments (ED), analysing management perspectives at macro, meso and micro levels. The second studied the management of the launch of a Major Trauma Centre introducing a Consultant Resident On-Call for trauma, which required temporary contracts. The research was conducted through case studies utilising semi-structured interviews. The ED was specifically chosen because of its high use of temporary staff, and its particular challenges associated with patient care. Results indicated a conflict between the priorities of senior management to minimise staff costs, and department level management, concerned with staffing levels to maintain patient care and service delivery. Risks to patient safety, particularly when ad-hoc agency staff were recruited, were identified. Study 2 revealed a shift from relational to transactional psychological contracts when consultants were placed on temporary contracts due to the protracted management of the change process and perceived psychological contract breach. The results highlighted the distinctive characteristics of temporary staffing in healthcare, and the hierarchy of preferences between the types of temporary staff identified. The research also revealed the consequences of the competing priorities between different management levels in the hospital. Finally, the studies revealed that the psychological contracts of temporary staff were predominantly transactional, whereas a more relational contract could improve temporary staff use and patient outcomes.

Abstract:
Petroleum refinery workers and service station attendants are continually exposed to benzene, toluene and xylene (BTX) due to the emission of volatile aromatic hydrocarbons (VAHs) in these environments. The objective of this study was to evaluate the health risk from exposure to BTX in service stations and benzene in petroleum refinery environments by using probabilistic techniques as well as development of exposure guidelines for risk to human health with benzene. The health risk resulting from exposure to BTX in service stations and benzene exposure in petroleum refineries was carried out by using data from scientific literature from 21 countries globally based on 23 research papers. The data were collected and collated into different scenarios for service stations and petroleum refinery environments based on activity, location and occupation and were plotted as cumulative probability distributions (CPD) plots. There were 6 scenarios for service station environments and 4 scenarios for petroleum refinery environments. The exposure data from service stations and petroleum refinery environments were calculated in terms of average daily dose (ADD) and lifetime average daily dose (LADD).

Abstract:
The economic downturn and ageing population has caused a rethink of a number of services: social housing providers are, as a result of the Coalition’s housing strategy (mainly enacted by the Localism Act 2011), not only considering who should be given low cost and secure housing, but for the first time, how long people should be housed. Demand is high for social properties and providers are urged to use their scare resources wisely; however, social housing is popularly viewed as a tenancy of last resort. This thesis explores a new phenomenon: why will the introduction of a policy to fix the term (length) of a tenancy be effective when social housing is considered not only to be the least desirable tenancy, but one that causes personal, economic and social difficulty. Surely, these issues alone would be enough of a stimulus for tenants to leave without any further limitations set by the State or the housing provider, if they were able to? This thesis uses the case study method to look at, in a highly qualitative way, the lived experiences of a number of tenants who have resided in their social homes for five years on traditional social tenancies. Fixed term tenancies will typically be five years in length and we are still a number of years away from being able to study what the actual impact will be. The issue is explored by understanding what would be the outcomes if the participants were on fixed term tenancies. As a result, a hermeneutic methodology was required. The study found that, good thing or not, fixed term tenancies are not shunned by likely applicants who, at the point of allocation, are not concerned about what might happen in five years’ time. In addition, an acute shortage of housing (across all tenures) is reducing the expectations of newly-forming households. Few tenants would not be offered a further tenancy (at the same or smaller property) at the end of five years as their circumstances are likely to remain largely unchanged.

The result was analyzed by definitions from Hasenfeld’s Human service organizations (HSO), Lipsky’s and Johansson’s definitions of "street-level bureaucrats", and room for manoeuvre. Lundquist’s definitions of "understand", "want" and "can" was also used, as well as the core-components that Fixsen, Naoom, Blase, Friedman och Wallace draw together of a successful implementation. The main result of the study indicates that the SoS-model contributes to the participation of children and parents and that it is complicated to implement the SoS-model in such a specialized organization. The study’s result also shows that the implementation is promoted by the support and the resources of every level in the organization and the fact that the initiative came from the street-level bureaucrats. The documentary system that comes with the BBIC is complicated to combinate with the SoS-model and therefore this might become a restricting effect.

Abstract:
Companies are expected to reduce the impact on society caused by its operations while at the same time, generate profit for its stakeholders. One way to satisfy both parts is by creating shared values. As the trend of servitization becomes more popular the ability of Product-Service Systems (PSS) to deliver additional value to customers arises. PSS provides an opportunity for developing a sustainable business model to benefit both the society and the stakeholders. A sustainable PSS can be based on the Triple Bottom Line dimensions, environment, economic, and social. Since the economic and environmental advantages have already been studied for PSS:s, the social aspect is yet to be studied in detail. This thesis focuses on the Occupational Safety and Health (OSH) theme of the social dimension, for PSS:s. Both the ability to improve the social dimension performance and the role it plays in the value proposition for PSS:s were studied. The thesis has been based on a case study on one company in a Business to Business market. It was found that customers seldom demanded or mentioned health and safety aspects for PSS:s, even when an increase of OSH was achieved by the PSS. However, it could also be concluded that all interviewed thought OSH was important for the company and the employees but there were divided opinions regarding OSH, if it would be put in the value proposition or not. By analysing the customer situation and how it operates, companies should use the customizability of PSS:s to better match their requirements and thus develop the value proposition for the PSS. Cost estimations for accidents have been done which showed that one single accident can cause very high costs. It is a good investment to prevent risks which should be communicated when selling PSS:s. Furthermore, it is important to communicate both internally within the firm, and externally to customers, about what health and safety benefits the PSS will contribute with.
Företag förväntas att reducera påfrestningarna på samhället och miljön orsakade av deras verksamhet och samtidigt fortsätta generera värde till dess intressenter. Ett sätt att tillgodose båda parter är genom att skapa så kallade delade värden. Då trenden att tjänstefiera blir mer och mer populär finns det möjlighet för ett så kallat Produkt-Service System (PSS) att leverera mervärde till kunderna. PSS ger en möjlighet att utveckla en hållbar affärsmodell som gynnar både samhället och intressenterna. Ett hållbart PSS kan grundas på de tre byggstenarna för Triple Bottom Line, miljö, ekonomi och samhälle. Då de ekonomiska och miljömässiga fördelarna redan har studerats för PSS fokuserar denna studie på hur konceptet står sig för den samhälleliga aspekten. I denna rapport studeras arbetshälsa och säkerhet för PSS, både möjligheten att förbättra den samhälleliga aspekten i Triple Bottom Line samt vilken roll dessa värden spelar för en värdepropositionering för PSS. Rapporten har baserats på en fallstudie på ett företag inom marknaden för Business till Business. Det konstaterades att kunderna sällan efterfrågar eller nämner hälso- och säkerhetsaspekter i förhandlingar om PSS, även när en ökning av arbetshälsa och säkerhet uppnåddes. Hur som helst tyckte alla intervjuade att arbetshälsa och säkerhet var viktigt för företag och anställda men det var trots detta delade meningar om det borde vara en del av värdepropositioneringen eller inte. Genom att analysera kundernas situation och hur de arbetar borde företag använda anpassningsbarheten av PSS för att bättre matcha kundernas önskemål och således utveckla värdepropositioneringen för PSS. Kostnadsberäkningar för olyckor har genomförts som visar att en enskild olycka kan orsaka mycket höga kostnader. Det är en god investering att förebygga risker vilket borde kommuniceras vid försäljning av PSS:s. Det är viktigt att både kommunicera internt inom företaget samt externt till kunderna om de hälso- och säkerhetsaspekter som PSS bidrar med.

Abstract:
In my previous bachelor's thesis I studied an algorithm for the improvement of runway efficiency in normal condition: minimizing the occupation of the runway means serving the greatest number of aircraft with the least possible delay. But other important limitations of airports are the ones in force during low visibility when the number of movements allowed undergoes a relevant reduction. A solution could be the use of technology to support air traffic controllers and pilots to re-establish a good level of situational awareness in order to reduce the limitations in force. In Europe, the technological pillar of the ambitious Single European Sky initiative is the Single European Sky ATM Research project (SESAR). Inside the SESAR project, the RETINA concept is regarding the introduction of augmented reality in aerodrome control tower for the improvement of efficiency and capacity of airports. Within the RETINA concept this thesis aims to study the implementation of new safety nets for aerodrome control tower with the support of augmented reality. This study starts from introduction to air traffic services in order to focus on SESAR project and RETINA concept. Then, concept and graphical solution for Conflicting ATC Clearances Safety Net (CATC) are proposed. Due to Covid-19 pandemic in progress during the thesis work, the implementation and validation activities could not be carried out in RETINA simulator of the University of Bologna labs, so different stand-alone implementation in Unity and validation by questionnaire administered to air traffic controllers are used. This thesis work can be considered as the first iteration in the User-Centered Design process for CATC. After the analysis of the feedback, new iteration in which the design is driven and refined by user-centered evaluation could be setup.

Abstract:
Since its inception in 1965, the Level-of-Service (LOS) has proved to be an important and practical "quality of service" indicator for transportation facilities around the world, widely used in the transportation and planning fields. The LOS rates these facilities' traffic operating conditions through the following delay-based indicators (ordered from best to worst conditions): A, B, C, D, E and F. This LOS rating has its foundation on quantifiable measures of effectiveness (MOEs) and on road users' perceptions; altogether, these measures define a LOS based on acceptable traffic operating conditions for the road user, implying that traffic safety is inherent to this definition. However, since 1994 safety has been excluded from the LOS definition since it cannot be quantified nor explicitly defined. The latter has been the motivation for research based on the LOS-Safety relationship, conducted at the University of Central Florida (UCF). Using data from two of the most studied transportation facility types within the field of traffic safety, signalized intersections and multilane high-speed arterial corridors, the research conducted has the following main objectives: to incorporate the LOS as a parameter in several traffic safety models, to extend the methodology adopted in previous studies to the subject matter, and to provide a platform for future transportation-related research on the LOS-Safety relationship. A meticulous data collection and preparation process was performed for the two LOS-Safety studies comprising this research. Apart from signalized intersections' and multilane-high speed arterial corridors' data, the other required types of information corresponded to crashes and road features, both obtained from FDOT's respective databases. In addition, the Highway Capacity Software (HCS) and the ArcGIS software package were extensively used for the data preparation. The result was a representative and robust dataset for each LOS-Safety study, to be later tested and analyzed with appropriate statistical methods. Regarding the LOS-Safety study for signalized intersections, two statistical techniques were used. The Generalized Estimating Equations (GEEs), the first technique, was used for the analyses considering all periods of a regular weekday (i.e. Monday through Friday): Early Morning, A.M. Peak, Midday, P.M. Peak and Late Evening; the second technique considered was the Negative Binomial, which was used for performing an individual analysis per period of the day. On the other hand, the LOS-Safety study for multilane high-speed arterial corridors made exclusive use of the Negative Binomial technique. An appropriate variable selection process was required for the respective model building and calibration procedures; the resulting models were built upon the six following response variables: total crashes, severe crashes, as well as rear-end, sideswipe, head-on and angle plus left-turn crashes. The final results proved to be meaningful for the understanding of traffic congestion effects on road safety, and on how they could be useful within the transportation planning scope. Overall, it was found that the risk for crash occurrence at signalized intersections and multilane high-speed arterial corridors is quite high between stable and unacceptable operating conditions; it was also found that this risk increases as it becomes later in the day. Among the significant factors within the signalized intersection-related models were LOS for the intersection as a whole, cycle length, lighting conditions, land use, traffic volume (major and minor roads), left-turn traffic volume (major road only), posted speed limit (major and minor roads), total number of through lanes (major and minor roads), overall total and total number of left-turn lanes (major road only), as well as county and period of the day (dummy variables). For multilane-high speed arterial corridors, the final models included LOS for the road section, average daily traffic (ADT), total number of through lanes in a single direction, total length of the road section, pavement surface type, as well as median and inside shoulder widths. A summary of the overall results per study, model implications and each LOS indicator is presented. Some of the final recommendations are to develop models for other crash types, to perform a LOS-Safety analysis at the approach-level for signalized intersections, as well as one that incorporates intersections within the arterial corridors' framework.

Abstract:
Background. Despite the prevalence of sex work and strip clubs across Canadian urban geographies, few studies explore the occupational health and safety outcomes related to indoor male sex work, let alone male stripping whereby men dance for men. Moreover, the sexual service negotiation process in the sex work industry remains to be explored. In knowing that sexual practices with high HIV/STI rates occur in strip clubs (e.g., condomless oral, vaginal, and anal sex), as well as widespread psychoactive substance use among strippers, the purpose of this study was to explore the cultural features of male strippers’ work that impact their health and safety outcomes. Methodology. For this study, we recruited 14 male strippers working with male clients in a Canadian city. Critical ethnography was our espoused methodology. Through field observations, informal conversations, questionnaires, and semi-structured qualitative interviews, we explored the process of sexual transactions between strippers and clients. We used a postmodern angle to interpret our findings through the works of Deleuze, Guattari, and Foucault. Findings. The male strip club is a social matrix produced by the intersection of motivational forces: the motivation to gain money, pleasure, or intimacy, and the motivation to abide by socio-cultural and legal norms. It is upon a matrix of financial necessity and socio-cultural and legal constraints that sex work transactions unfold in the club. Moreover, the club’s health and safety conditions and strippers’ transaction outcomes result from intersecting motivations. Finally, sexual service negotiation is a process of configuring motivational forces between social agents. The motivation for financial gain revealed itself to be the strongest and most consistent force; the focus on capital gain generated asymmetrical connections between strippers, clients, and business entrepreneurs, resulting in specific health and safety outcomes. Conclusion. The Canadian legal and political context surrounding male sex work negatively impacts male strippers’ occupational health and safety conditions by disabling safe connections with clients. Further, the emphasis on money-making activities encourages strippers to value financial gain over their physical and mental integrity. In short, the male strip club work environment is configured in a manner whereby capital gain is prioritized and strippers’ health and safety is undermined.

According to the statistic data, there are 99.68% of the vehicles using gasoline in Taiwan. It shows that petroleum is the major energy resource in Taiwan. Facing the high petroleum prices and unstable situations, it’s important to try to use diverse energy resources. The government urges the public trying to use LPG. In addition to the diverse energy resources policy, it could reduce the amount of the vehicle contamination. It’s not easy to find a LPG service station in Taiwan, and these results in less LPG vehicles. The major reason that causing of less LPG service station is there are no professional consulters to help companies building the LPG service station. Although the Ministry of Economic Affairs, R.O.C. draw up the “LPG vehicles service station establishment manual”, it is not enough for the building process, especially for the “constructing the LPG service station”. This study tries discussing the safety planning for LPG service station, and tries to draw up the “LPG service station designing and construction manual”. It could be helpful to establish the safe LPG service station, eliminate customers’ anxiety, and could increase the growing rate of the LPG service station. This study adapts the literature review method and risk assessing method to study the safety planning for the LPG service station. The study searches the LPG service station accident which comes from Japan, Hong Kong, China, South Korea and U.S. to discuss the key safety factor for building the LPG service station. The study also compares the safety planning of the LPG service station in Holland, Japan, Australia and Hong Kong with in Taiwan. The study assesses the influence of different degree of the LPG service station safety planning to discuss the proper protection planning. The proper protection planning could decrease the risk. This study tries to draw up the “Standard design and building process of LPG service station“, which might refer to the “Rule of the LPG service station building up and management”, and “LPG and petrol/diesel service stations engineering mechanical/electrical design and construction standard”. All these works is trying to build up a safety plan for the LPG service station.

In the last hundred years the medical technology has advanced rapidly and the medical environment has improved a great deal, and the death rate consequently plummeted. As people live longer, the aging society began to experience increased medical expenses which, in turn, has become the primary burden to advanced nations around the world. The biggest component in the medical expenses today is associated with the treatment and care of patients with chronic illnesses. The treatment of chronic patients is mostly through applying drugs, and the interaction among drugs as well as the physiological characteristics of patients may cause undesirable side effects. Patients also may have misconceptions in drug applications. They purchased over-the-counter drugs or they go to a number of doctors for treatment simultaneously, causing the fragmentation of their medical information, which increases the risk of undesired drug interactions, not even mentioning the waste of resources on unused or wrongly used medicines. This research attempts to increase the drug safety through designing a patient-centered drug information system. Using existing standards to integrate the drug-usage information between different hospitals. We also provide personal drug records through cloud service to let user confirm the information easily, so that we can compare the information we saved with the medication safety system instantly. To identify the exclusive medicine and finally return it through a general user interface to medical institute which is need of complete drug usage information. Forming a overall drug safty condition for the patients. This study implements SOA (Service-Oriented Architecture) and develops modular service component for quick response to system changes.
