Russian Securitisation Framing of Ukraine Between February 2019 – February 2023Arnould, Natalie Kaja January 2023 (has links)
The Russian-Ukrainian relationship is inherently complex. Since the end of the Cold War, there have been several defining moments in this relationship, which have contributed to how Russia perceives any potential challenges to its security. Securitising discourse from Russian political leadership, namely the President, offers an insight into what aspects of this relationship are escalated so extensively that extreme courses of action may be deemed necessary (i.e., a full-scale invasion of Ukraine). Drawing on Buzan et al. (1998), this project identifies the key sectors that Russia politicises, and those that it securitises vis-à-vis Ukraine. In addition, this study highlights the key sub-themes within politicisation and securitisation that were found within these sectors. This is all within a timeframe where relations have moved from comparatively stable to a time of war (February 2019 – February 2023). There is some degree of overlap between the themes politicised and securitised, especially across the military, political, societal, and economic sectors of security. There were no cases of securitisation within the environmental sector. Overall, this study found a significant shift in Russia’s securitisation framing of Ukraine from mid-2021 onwards.

A pattern-driven and model-based vulnerability testing for Web applications / Une approche à base de modèles et de patterns pour le test de vulnérabilités d'applications WebVernotte, Alexandre 29 October 2015 (has links)
Cette thèse propose une approche originale de test de vulnérabilité Web à partir de modèles etdirigée par des patterns de tests, nommée PMVT. Son objectif est d’améliorer la capacité de détectionde quatre types de vulnérabilité majeurs, Cross-Site Scripting, Injections SQL, Cross-Site RequestForgery, et Privilege Escalation. PMVT repose sur l’utilisation d’un modèle comportemental del’application Web, capturant ses aspects fonctionnels, et sur un ensemble de patterns de test devulnérabilité qui adressent un type de vulnérabilité de manière générique, quelque soit le type del’application Web sous test.Par l’adaptation de technologies MBT existantes, nous avons développé une chaîne outillée complèteautomatisant la détection des quatre types de vulnérabilité. Ce prototype a été exprimenté et évaluésur deux applications réelles, actuellement utiliseés par plusieurs dizaines de milliers d’utilisateurs.Les résultats d’expérimentation démontrent la pertinence et de l’efficience de PMVT, notamment enaméliorant de façon significative la capacité de détection de vulnérabilités vis à vis des scannersautomatiques d’applications Web existants. / This thesis proposes an original approach, dubbed PMVT for Pattern-driven and Model-basedVulnerability Testing, which aims to improve the capability for detecting four high-profile vulnerabilitytypes, Cross-Site Scripting, SQL Injections, CSRF and Privilege Escalations, and reduce falsepositives and false negatives verdicts. PMVT relies on the use of a behavioral model of theapplication, capturing its functional aspects, and a set of vulnerability test patterns that addressvulnerabilities in a generic way. By adapting existing MBT technologies, an integrated toolchain that supports PMVT automates thedetection of the four vulnerability types in Web applications. This prototype has been experimentedand evaluated on two real-life Web applications that are currently used by tens of thousandsusers. Experiments have highlighted the effectiveness and efficiency of PMVT and shown astrong improvement of vulnerability detection capabilities w.r.t. available automated Web applicationscanners for these kind of vulnerabilities.

Nurse managers attitudes and perceptions regarding cost containment in public hospitals in the Port Elizabeth metropoleNtlabezo, Eugenia Tandiwe 31 March 2003 (has links)
This study investigated the attitudes and perceptions of nurse managers regarding cost containment issues in selected public hospitals in the Port Elizabeth metropole of the Eastern Cape. Four hospitals participated in the study, and 211 nurse managers completed questionnaires. The results obtained from the participants’ responses indicated that:
✦ Nurse managers are ill-prepared for many responsibilities regarding cost containment, and need appropriate orientation and preparation both during their initial formal, and during their nurse management and in service training in order to fulfil their “financial” or cost containment role more effectively.
✦ Nurse managers perceived the relationship between the productivity of staff and cost containment positively, but were reportedly unable to
• prevent nurses from leaving their points of duty
• curb the rate of absenteeism among nurses
• reduce the number of resignations
✦ Nurse managers suggested that more effective hospital cost containment efforts should ensure that
• effective security checks are performed to curb losses of stock and equipment
• more public telephones are installed in hospitals
• stricter controls regarding wheelchairs are implemented
The rationalisation of staff and services, as well as specialised equipment among the four public hospitals could enhance these hospitals’ cost containment results. However, this would necessitate reorganising these hospitals’ services at provincial level.
The nurse managers required more knowledge about hospitals’ financial management and cost containment issues. Guidelines for such a course were developed addressing: analysis of monthly variance reports; budgeting for manpower; balance statement; calculations for the supplies and expenses budget; income statements; the hospital’s budgetary cycle; break-even analysis; analysis of cost-effectiveness and cost-benefit analysis. / ADVANCED NURSING SCIENCES / D.Litt. et Phil.

Model-Based Optimization of Clinical Trial DesignsVong, Camille January 2014 (has links)
General attrition rates in drug development pipeline have been recognized as a necessity to shift gears towards new methodologies that allow earlier and correct decisions, and the optimal use of all information accrued throughout the process. The quantitative science of pharmacometrics using pharmacokinetic-pharmacodynamic models was identified as one of the strategies core to this renaissance. Coupled with Optimal Design (OD), they constitute together an attractive toolkit to usher more rapidly and successfully new agents to marketing approval. The general aim of this thesis was to investigate how the use of novel pharmacometric methodologies can improve the design and analysis of clinical trials within drug development. The implementation of a Monte-Carlo Mapped power method permitted to rapidly generate multiple hypotheses and to adequately compute the corresponding sample size within 1% of the time usually necessary in more traditional model-based power assessment. Allowing statistical inference across all data available and the integration of mechanistic interpretation of the models, the performance of this new methodology in proof-of-concept and dose-finding trials highlighted the possibility to reduce drastically the number of healthy volunteers and patients exposed to experimental drugs. This thesis furthermore addressed the benefits of OD in planning trials with bio analytical limits and toxicity constraints, through the development of novel optimality criteria that foremost pinpoint information and safety aspects. The use of these methodologies showed better estimation properties and robustness for the ensuing data analysis and reduced the number of patients exposed to severe toxicity by 7-fold. Finally, predictive tools for maximum tolerated dose selection in Phase I oncology trials were explored for a combination therapy characterized by main dose-limiting hematological toxicity. In this example, Bayesian and model-based approaches provided the incentive to a paradigm change away from the traditional rule-based “3+3” design algorithm. Throughout this thesis several examples have shown the possibility of streamlining clinical trials with more model-based design and analysis supports. Ultimately, efficient use of the data can elevate the probability of a successful trial and increase paramount ethical conduct.

Evaluation of proton treatment strategies for head and neck cancer and lung cancer based on treatment planning studiesJakobi, Annika 26 July 2016 (has links) (PDF)
The clinical introduction of proton therapy requires an extensive analysis of its benefits compared to conventional radiotherapy and a detailed analysis of possible uncertainties which might have serious consequences for patient treatment. In the first part of the presented thesis, the expected toxicities were evaluated for a treatment of head and neck cancer patients using a biologically adapted dose escalation schedule with photon and proton therapy. The feasibility of the dose escalation schedule could be demonstrated for both photon and proton therapy, since only a small increase in toxicity risk occurred for most toxicities. However, the expected toxicity risks were in most cases smaller with proton therapy. Furthermore, a higher benefit was found for patients with primary tumour locations in the upper head and neck area, who thus might be preferably referred to proton therapy. In the second part of this thesis, an extensive analysis of the impact of tumour motion in lung cancer treatment with active-scanning proton therapy was conducted. It could be shown, that dose degradations were small for tumour motion amplitudes below 5 mm. Parameters like the target volume concept, the optimisation approach, changes in the motion pattern and application sequence times had additional impact on the dose degradation. However, their magnitude was patient specific. Since not all parameters can be assessed before treatment, e.g. the motion pattern during treatment, prospective estimations should be supplemented by retrospective analyses. / Die Einführung der Protonentherapie in die klinische Praxis erfordert umfassende Analysen ihrer Vor- und Nachteile im Vergleich zur konventionellen Photonentherapie sowie detaillierte Untersuchungen der Auswirkungen von Unsicherheiten in der Therapieapplikation. Im ersten Teil der vorliegenden Arbeit wurden die zu erwartenden Nebenwirkungen bei der Behandlung von Patienten mit Kopf-Hals-Tumoren mit einem biologisch-adaptierten Fraktionierungsschema inklusive Dosiseskalation mit Photonen- und Protonentherapie evaluiert. Dabei konnte gezeigt werden, dass die Dosiseskalation sowohl mit Photonen- als auch Protonentherapie angewandt werden kann, da die Wahrscheinlichkeit für das Auftreten von Nebenwirkungen in den meisten Fällen kaum erhöht wurde. Weiterhin wurden die Nebenwirkungswahrscheinlichkeiten mit der Protonentherapie im Vergleich zur Photonentherapie reduziert. Dies war vor allem für Patienten mit Tumoren im oberen Kopf-Hals-Bereich der Fall. Diese könnten daher bevorzugt zur Protonentherapie überwiesen werden. Darüber hinaus wurde im zweiten Teil der Arbeit eine umfassende Analyse des Einflusses der Tumorbewegung auf die Dosisverteilung bei Behandlung von Lungentumoren mit aktiver Protonenstrahlformierung durchgeführt. Dabei zeigte sich, dass Dosisdegradierungen bei Bewegungsamplituden unter 5mm gering sind. Parameter wie das Zielvolumenkonzept, Veränderungen des Bewegungsmusters oder der Applikationszeiten nehmen zusätzlich Einfluss auf die Dosisdegradierung, allerdings in unterschiedlichem Maß für individuelle Patienten. Da nicht alle Parameter vor Behandlung bekannt sein können, sollten prospektive Dosisabschätzungen durch retrospektive Analysen ergänzt werden.

以推敲可能性理論探討軟體專案承諾升級 / Escalation of Commitment in Software Projects: An Elaboration Likelihood Model Perspective張菀庭, Chang, Wan-Ting Unknown Date (has links)
軟體專案承諾升級現象發生時,可能會造成更多資源成本的投入,若投入更多的資源,而專案依然失敗,則會造成更多的浪費,是企業界最不希望看到的情形。本研究利用推敲可能性理論探討此現象,了解不同的說服方式如何影響受測者的決策過程。根據遇到專案的狀況,依照訊息訴求分成理性訴求與感性訴求的敘述方式,加入框架效應 (正向/負向) 以及訊息強度 (低/中/高) 兩變數,以自我責任作為調節變項進行探討,研究在不同情況敘述下,決策制定者接收專案訊息描述後其決策過程中的推敲可能性,以及推敲可能性與決策之間的關係。
研究發現如下:
1. 單一效果影響下,訊息強度中比起其他兩個強度較容易引起訊息接收者運用中央路徑思考。
2. 訊息訴求、訊息框架以及訊息強度會交互影響受測者推敲可能性,在正向框架下,訊息訴求與訊息強度對訊息接收者運用中央路徑做決策有顯著的交互作用。
3. 在訊息強度中與強的情況下訊息訴求與訊息框架對訊息接收者運用中央路徑做決策有顯著的交互作用。
4. 在感性訴求、正向框架與訊息強度強的訊息描述下,訊息接收者運用中央路徑思考時,較不容易做出承諾升級的決定。
5. 在自我責任調節下,則是感性訴求、負向框架與訊息強度弱的訊息描述,會引起訊息接收者運用中央路徑思考時,較不容易做出專案繼續的決策。 / Escalation of commitment is common in software project development. There are a few theories that have been used to explain this behavior, including the framing effect and self-responsibility. This study investigates the issue from the dual-path elaboration likelihood model (ELM) to examine how different persuasion routes may play roles in the decision process. An experiment was designed to study the effect of different descriptions of project status that may lead to different decision routes (central versus peripheral routes). The experiment design includes message appealing (rational vs emotional appealing), message strength (strong, medium and weak), and framing (positive vs. negative) as main variables and the responsibility as a moderator. The
subject was asked to decide whether s/he would continue the project under a given scenario. Our results includes the following:
1. Message appealing, message framing, and message strength have significant interaction effect on the subject’s decision routes;
2. In positive framing, message appealing and strength has significant interaction effect on the use of the central route;
3. When message strength is medium or strong, message appealing and framing has significant interaction effect on the use of the central route;
4. Regarding to decision escalation, the likelihood of escalation is lower when the decision route is central (thinking) under the emotional appealing, positive framing, and strong message;
5. The likelihood of escalation is lower when the decision route is central under the emotional appealing, negative framing, and weak message description.
