Makrosäkring : Intressenters attityder till redovisning av dynamisk riskhantering / Macro Hedging : Stakeholders’ attitudes towards Accounting for Dynamic Risk Management

Andersson, Malin, Atterflod, Natalie January 2015 (has links)
Säkringsredovisning används vid redovisning av finansiella instrument som innehas i säkringssyfte. Det är svårt att tillämpa nuvarande regler för säkringsredovisning på makro-säkringar, särskilt när portföljer hanteras dynamiskt. På grund av begränsningarna i nuvarande säkringsredovisning har många företag svårt att tillförlitligt presentera resultatet av dynamisk riskhantering i de finansiella rapporterna. Effekten blir att vissa företag undviker att använda säkringsredovisning medan andra endast tillämpar säkringsredovisning till viss del. En del företag använder istället andra säkringstekniker som inte fullständigt återspeglar den dynamiska riskhanteringen. IASB har publicerat ett diskussionsunderlag (DP) som presenterar en redovisningsmetod för dynamisk riskhantering. Målet med den nya metoden Portfolio Revaluation Approach (PRA) är att uppnå en tillförlitlig presentation samt reducera den nuvarande operativa komplexiteten.Syftet med studien är att undersöka och jämföra IASB:s intressenters attityder till redovisning av dynamisk riskhantering och identifiera deras attityder till den föreslagna redovisnings-metoden PRA. Studien syftar dessutom till att kartlägga intressenternas attityder till hur en framtida metod bör utformas. I studien genomförs en kvalitativ innehållsanalys för att skapa en uppfattning av intressenternas attityder. Studien baseras på 30 remissvar som inkommit från intressenter som svar på IASB:s utgivna DP om makrosäkring. Intressentgrupperna som studien baseras på är normgivare, revisionsbolag och företag.Studien visar att intressenterna anser att det uppstår problem när nuvarande regler tillämpas på dynamiskt hanterade portföljer. IASB bör därför utveckla regler som återspeglar och blir tillämpbara på dynamisk riskhantering. Remissvaren visar dock att åsikterna om makro-säkringsprojektets omfattning och vad dynamisk riskhantering bör innefatta skiljer sig åt. IASB har frångått det initiala målet med projektet och utökat omfattningen. Intressenterna kräver därför att IASB tydliggör målet innan ett utkast (ED) utvecklas.Studien påvisar att åsikterna om PRA är skilda. Intressenterna har dock identifierat fler nackdelar än fördelar med PRA. Enligt intressenterna bör en framtida redovisningsmetod för dynamisk riskhantering endast tillämpas när riskerna har minimerats genom säkring och inte vid all dynamisk riskhantering. Intressenterna anser att en tillämpning på alla dynamiska riskhanteringsaktiviteter skulle öka resultatvolatiliteten och inte resultera i användbar information. Studien visar att en framtida redovisningsmetod för dynamisk riskhantering bör vara frivillig att tillämpa. Intressenterna anser att metoden bör utformas för att kunna tillämpas på alla risker, inte enbart ränterisker. Enligt intressenterna bör IASB inte utveckla en helt ny metod utan istället utforma en metod som bygger på befintliga regler i IFRS 9 Finansiella instrument och IAS 39 Finansiella instrument: Redovisning och värdering. IASB bör dessutom utforma principbaserade regler eftersom att den dynamiska riskhanteringen är föränderlig. IASB måste säkerställa att metoden är praktisk genomförbar. Vår slutsats är att intressenterna förvisso uppmuntrar IASB:s makrosäkringsprojekt men få är tillfredsställda med det som presenteras i DP. / Hedge accounting is used when accounting for financial instruments held for hedging purposes. There are difficulties associated with applying existing hedge accounting requirements to macro hedges particularly when portfolios are managed dynamically. Because of the limitations of existing hedge accounting many entities find it difficult to faithfully present the results of dynamic risk management in the financial statements. As a result, some entities do not apply hedge accounting at all while others only apply parts of hedge accounting. Some entities apply other hedging techniques which do not correctly reflect the dynamic risk management. The IASB has published a Discussion Paper (DP) featuring an accounting method for dynamic risk management. The objective of the new method Portfolio Revaluation Approach (PRA) is to achieve a faithful presentation of dynamic risk management and reduce the existing operational complexity.The purpose of the study is to examine and compare the attitudes of the IASB’s stakeholders towards accounting for dynamic risk management and identify their opinion on the proposed accounting method PRA. The study also aims to identify stakeholders’ views on how a future method should be designed. To obtain an understanding of stakeholders’ views a qualitative content analysis were used. The study is based on 30 comment letters received from stakeholders in response to the issued DP on macro hedging. The stakeholders where categorized into three groups: standard setting bodies, accounting firms and corporations.The study shows that stakeholders consider that problems arise when the current rules is applied to dynamically managed portfolios. The IASB should develop rules that will be applicable and reflect dynamic risk management. The comment letters shows different opinions about the scale of the project and what dynamic risk management should cover. The IASB has modified the initial objective of the project and expanded the scope. Stakeholders therefore require that the IASB clarifies the objective before they develop an Exposure Draft (ED).The study found that opinions on PRA are diverse. Stakeholders have, however, identified more disadvantages than advantages with PRA. According to stakeholders, a future accounting method for dynamic risk management should be applied only when risk mitigation has been undertaken by hedging and not applied on all dynamic risk management. Stakeholders believe that an application on all dynamic risk management activities would increase volatility in profit or loss and not result in useful information. Furthermore, the study shows that a method should be optional to apply. A future accounting method should be designed to be applicable to all risks, not only interest rate risks. Judging by the commentIIletters from the stakeholders, the IASB should not develop a new method but instead design a method based on the existing rules in IFRS 9 Financial instruments and IAS 39 Financial Instruments: Recognition and Measurement. Moreover, the IASB should develop principle-based rules because of the character of dynamic risk management. The IASB must ensure that the method is practicable. Our conclusion is that even though the stakeholders encourage the macro hedging project, few are satisfied with the proposal submitted.(This paper is written in Swedish)

Jak ptáci poznávají predátory - význam úplnosti vizuální informace / How do the birds recognize predators - importance of complete visual information

TVARDÍKOVÁ, Kateřina January 2009 (has links)
Pair-wise preferential experiments were used to reveal dangerous predator differentiation and ability of amodal completion by four tit species. Firstly was revealed that the tits{\crq} behaviour towards the feeder was in agreement with predictions of the dynamic risk assessment theory. The presence of any predator at the feeder lowered the number of visits to the feeder. Likewise, the tits evaluated the sparrowhawk as more dangerous than the kestrel because its presence lowered the number of visits more than the kestrel. Secondly, we observed tits{\crq} reactions to both partly occluded and amputated dummy of sparrowhawk in two different treatments (torsos vs. complete dummy of pigeon, torsos vs. complete dummy of sparrowhawk). All birds clearly classified both torsos as ``full-featured{\crqq} predators and kept away of them when pigeon on the second feeder. However, when sparrowhawk was presented on the second feeder, number of visits to amputated predator was higher than to occluded one. Birds risked arriving to ``utter{\crqq} amputated torso while the fear of ``full-featured{\crqq} occluded torso stayed without change when second feeder did not provide safe alternative. Such discrimination between torsos needs ability of amodal completion.

An exploration of the perceptions of non-admitting sex offenders of their family environment

Davids, Olivia Davene January 2014 (has links)
Magister Artium - MA / This study aims to explore the family environment of non-admitting sex offenders in order to gain insight into the family characteristics that could be contributing factors towards the behaviour of denial. However, the focus will not be on the families of the sex offenders, but rather on the non-admitting sex offenders’ views of their family environment. The theoretical framework used is the Social Learning Theory, because it supports the fact that most behaviour is learned through modelling the behaviour of others. The researcher used a qualitative approach and the aim of the study was to generate information that would describe the family environment of non-admitting sex offenders. The population of this study was incarcerated, sentenced sex offenders with specific focus on the non-admitting sex offender as the unit of analysis. Ten (10) participants were purposively selected for the study and semi-structured interviews were conducted with each one in order to generate the needed information for the study

Gains de traitement sur des facteurs de risque dynamique et leurs liens avec la récidive chez des agresseurs sexuels à risque et besoin modérés à élevés

Larouche Wilson, Alexa 09 1900 (has links)
Thèse de doctorat présenté en vue de l'obtention du doctorat en psychologie - recherche intervention, option psychologie clinique (Ph.D) / Evaluating treatment programs specialized in treating sexual offenders and reducing recidivism, especially sexual recidivism, is of great importance to the general public and policy makers because of the many physical and psychological consequences these crimes have on the victims and their families. The present study evaluated the changes that occurred in moderate to high risk sexual offenders who followed a specialized community treatment program. In order to accomplish this, gains during treatment and their ability to predict lower recidivism rates was examined using three different methods of measurement: risk assessment, self-reports, and phallometric testing. Change scores were derived from the Stable-2007 and its three dimensions (i.e., antisociality, sexual deviance, and hypersexuality); the Molest and Rape Scale; the Sexual Interest Cardsort Questionnaire; and phallometric testing. Measures were administered pre- and posttreatment in a sample of 105 adult male sexual offenders with adult and child victims. Recidivism data were obtained from official criminal records. The average follow-up period for participants was of 12 years postrelease. Findings were indicative of significant positive changes in dynamic risk factors as measured by the Stable-2007 and its three dimensions; in PSIs as measured by the Sexual Interest Cardsort Questionnaire and phallometric testing; but not in cognitive distortions as measured by the Molest and Rape Scale. The majority of change scores were non significantly associated with reductions in sexual, violent, or general recidivism after controlling for pretreatment and static risk. Comparing the different methods of measurement in their ability to capture changes and predict recidivism was unable to be done due to the lack of significant results. The following study is only the second to examine treatment change on the Stable-2007 and its relationship to recidivism, and the first examining treatment change in its three different dimensions. Although the program seemed to be effective in reducing certain dynamic risk factors, the relationships between treatment change and lower recidivism rates, especially sexual recidivism remains unclear. More studies examining treatment change on specific dynamic risk factors using different measures are needed to establish more comprehensive conclusions about which dynamic risk factors are more susceptible to change and most effective if reducing recidivism rates. / L’évaluation des traitements visant la réduction des taux de récidives, surtout sexuelle, chez les agresseurs sexuels est un sujet de grande importance due aux conséquences physiques et psychologiques que ces crimes ont sur les victimes et leurs familles. Pour ces raisons, la présente étude avait comme objectif principal d’évaluer des changements suivant la participation d’un programme de traitement en communauté spécialisé dans le traitement d’agresseur sexuel à risque et aux besoins modérés à élevés. Pour accomplir ceci, les gains acquis sur différents facteurs de risques dynamiques et leurs capacités de prédire la récidive ont été examinés. Les gains ont été mesurés en utilisant une échelle d’évaluation du risque dynamique de récidive, des questionnaires auto-rapportées et des évaluations phallométriques. La Stable-2007 et ses trois dimensions (c.-à-d. antisocial, déviance sexuelle, et hypersexualité) ont été utilisées pour mesurer plusieurs facteurs de risques dynamiques, le Molest and Rape Scale ont été utilisés pour mesurer les distorsions cognitives, et le Sexual Interest Cardsort Questionnaire et l’évaluation phallométrique ont été utilisés pour mesurer les intérêts sexuels paraphiliques. Toutes les mesures ont été administrées pré et posttraitement à 105 agresseurs sexuels avec des victimes soit adultes et/ou enfants ayant complété le programme de traitement. Les données de récidives ont été obtenues des dossiers criminels officiels avec une période de suivi moyenne de 12 ans. Suite à la complétion du programme de traitement, il y a eu des gains significatifs sur les facteurs de risque dynamiques mesurés par la Stable-2007 et ses trois dimensions, et sur les intérêts sexuels paraphiliques mesurés par le Sexual Interest Cardsort Questionnaire et l’évaluation phallométrique. Cependant, aucune amélioration n’a été trouvée pour les distorsions cognitives. En examinant la relation prédictive entre les gains sur ces mesures et les taux de récidives, la majorité des changements positifs n’étaient pas significativement associés à des réductions de taux de récidive sexuel, violent et général, après avoir contrôlé pour le risque prétraitement et statique. Due aux résultats non-significatives, la capacité des différentes mesures à identifier des changements et prédire la récidive n’a pas pu être comparé. Cette étude est la deuxième étude examinant des changements pré à posttraitement sur la Stable-2007 et la première à examiner ses changements sur les trois dimensions de la Stable-2007. Même si le programme de traitement évalué semble être capable de produire des changements positifs dans certains facteurs de risque dynamiques, la relation entre ces gains et leurs capacités de prédire des taux plus bas de récidives reste contradictoire et incertaine. Plus d’études examinant les gains sur des facteurs risques dynamiques spécifiques en utilisant différentes mesures sont nécessaires avant de pouvoir vraiment établir les facteurs dynamiques les plus susceptibles à changer et prédire des taux de récidive plus bas.

A restorative approach towards school discipline and behavioural conduct in South African schools: a case study

Buys, Irma 09 1900 (has links)
Misconduct, antisocial and offending (criminal) behaviour is becoming a problem in South African schools and maintaining discipline in schools is facing many challenges. Current practices do not solve disciplinary challenges. This study reflects upon the discipline system in South African schools as well as risk factors playing a role in possible offences, by means of a case study. An enormous number of learners are still experiencing difficulties concerning their education because of their disadvantaged position in South Africa. In cases where there are disruptions of the learning process due to ill-discipline and antisocial behaviour, it leads to unsuccessful education in a country where there are already obstacles underlying the foundation of the education system. It is important to have an effective disciplinary system implemented in schools. The discipline system in South African schools, currently, views a learner as an offender, when behaviour is such that it is against the school’s rules. The focus is then on proving the offender guilty and then punishing him/her in order to proof that responsibility is taken by the school for his/her actions. The learner punished, in some cases rebel and this leads to further divergent behaviour. In the current school discipline system, the victim plays no role in the process and the changes needed in the discipline process should include the victim. The discipline process should move from a punitive to a restorative system. In a restorative discipline system, intervention plays an important role. The study also places focus on identifying possible risk behaviour at an early age and explored risk factors that may play a role in the management of discipline related concerns and conduct. This process plays a significant role in the intervention process, as learners can be identified and counselled before offending behaviour takes place or intervention can take place the moment that the learner is involved in deviant behaviour. Dynamic risk factors, for example antisocial friends, antisocial behaviour and lack of respect for authority can be addressed through restorative rather than punitive intervention. This study was also directed to develop a South African theoretical framework to be used by schools and the Department of Education, as an alternative to the current punitive system through the application of restorative practices as a support to troubled learners. / Criminal and Procedural Law

Forecasting of flash-flood human impacts integrating the social vulnerability dynamics / Prévision des impacts humains conséquences des crues rapides intégrant le concept de vulnérabilité sociale dynamique

Terti, Galateia 27 March 2017 (has links)
Au XXIe siècle, la prévision de l'aléa hydrométéorologique et des impacts associés aux crues rapides demeurent un défi pour les prévisionnistes et les services de secours. Les mesures structurelles et / ou les avancées des systèmes de prévision hydrologique ne garantissent pas, à elles seules, la réduction des décès lors de ces phénomènes d'inondation rapide. La littérature souligne la nécessité d'intégrer d'autres facteurs, liés aux processus de vulnérabilité sociaux et comportementaux, afin de mieux prendre en compte les risques encourus par les populations lors de ces épisodes extrêmes. Cette dissertation conduit une analyse théorique couplés à ceux de une analyse des accidents historiques mortels afin d'expliquer les interactions qui existent entre les processus hydrométéorologiques et sociaux responsables de l'apparition de vulnérabilités humaines lors de crues rapides aux États-Unis. Des données d'enquêtes liées aux crues rapides sont examinées afin d'élaborer un système de classification des circonstances du décès (en voiture, à l'extérieur, à proximité d'un cours d'eau, dans un camping, dans un bâtiment ou en mobile-home). L'objectif est d'établir un lien entre la conception des vulnérabilités et l'estimation des pertes humaines liées à ces catastrophes naturelles. "Random forest" est utilisé et est basé sur un arbre de décision, qui permet d'évaluer la probabilité d'occurrence de décès pour une circonstance donnée en fonction d'indicateurs spatio-temporels. Un système de prévision des décès liés à l'usage de la voiture lors des crues rapides, circonstance la plus répandue, est donc proposé en s'appuyant sur les indicateurs initialement identifiés lors de l'étude théorique. Les résultats confirment que la vulnérabilité humaine et le risque associé varient de façon dynamique et infra journalière, et en fonction de la résonance spatio-temporelle entre la dynamique sociale et la dynamique d'exposition aux dangers. Par exemple, on constate que les jeunes et les personnes d'âge moyen sont plus susceptibles de se retrouver pris au piège des crues rapides particulièrement soudaines(par exemple, une durée de près de 5 heures) pendant les horaires de travail ou de loisirs en extérieur. Les personnes âgées sont quant à elles plus susceptibles de périr à l'intérieur des bâtiments, lors d'inondations plus longues, et surtout pendant la nuit lorsque les opérations de sauvetage et / ou d'évacuation sont rendues difficiles. Ces résultats mettent en évidence l'importance d'examiner la situation d'exposition aux risques en tenant compte de la vulnérabilité dynamique, plutôt que de se concentrer sur les conceptualisations génériques et statiques. Ce concept de vulnérabilité dynamique est l'objectif de modélisation développée dans cette thèse pour des vulnérabilités liés aux véhicules. À partir de l'étude de cas sur les crues rapides survenues en mai 2015, et en analysant principalement les états du Texas et de l'Oklahoma, principaux états infectés par ces évènements,le modèle montre des résultats prometteurs en termes d'identification spatio-temporelle des circonstances dangereuses. Cependant, des seuils critiques pour la prédiction des incidents liés aux véhicules doivent être étudiés plus en profondeur en intégrant des sensibilités locales non encore résolues par le modèle. Le modèle établi peut être appliqué, à une résolution journalière ou horaire, pour chaque comté du continent américain. Nous envisageons cette approche comme une première étape afin de fournir un système de prévision des crues rapides et des risques associés sur le continent américain. Il est important que la communauté scientifique spécialisée dans l'étude des crues éclairs récoltent des données à plus haute résolution lorsque ces épisodes entrainement des risques mortels, et ce afin d'appuyer la modélisation des complexités temporelles et spatiales associées aux pertes humaines causées par les futures inondations soudaines. / In the 21st century the prediction of and subsequent response to impacts due to sudden onset and localized flash flooding events remain a challenge for forecasters and emergency managers. Structural measures and/or advances in hydrological forecasting systems alone do not guarantee reduction of fatalities during short-fuse flood events. The literature highlights the need for the integration of additional factors related to social and behavioral vulnerability processes to better capture risk of people during flash floods. This dissertation conducts a theoretical analysis as well as an analysis of flash flood-specific historic fatalities to explain complex and dynamic interactions between hydrometeorological, spatial and social processes responsible for the occurrence of human life-threatening situations during the "event" phase of flash floods in the United States (U.S.). Individual-by-individual fatality records are examined in order to develop a classification system of circumstances (i.e., vehicle-related, outside/close to streams, campsite, permanent buildings, and mobile homes). The ultimate goal is to link human vulnerability conceptualizations with realistic forecasts of prominent human losses from flash flood hazards. Random forest, a well-known decision-tree based ensemble machine learning algorithm for classification is adopted to assess the likelihood of fatality occurrence for a given circumstance as a function of representative indicators at the county-level and daily or hourly time steps. Starting from the most prevalent circumstance of fatalities raised from both the literature review and the impact-based analysis, flash flood events with lethal vehicle-related accidents are the subject to predict. The findings confirm that human vulnerability and the subsequent risk to flash flooding, vary dynamically depending on the space-time resonance between that social and hazard dynamics. For example, it is found that younger and middle-aged people are more probable to get trapped from very fast flash floods (e.g., duration close to 5 hours) while participating in daytime outdoor activities (e.g., vehicle-related, recreational). In contrary, older people are more likely to perish from longer flooding inside buildings, and especially in twilight and darkness hours when rescue and/or evacuation operations are hindered. This reasoning places the importance of situational examination of dynamic vulnerability over generic and static conceptualizations, and guides the development of flash flood-specific modeling of vehicle-related human risk in this thesis. Based on the case study of May 2015 flash floods with a focus in Texas and Oklahoma, the model shows promising results in terms of identifying dangerous circumstances in space and time. Though, critical thresholds for the prediction of vehicle-related incidents need to be further investigated integrating local sensitivities, not yet captured by the model. The developed model can be applied on a daily or hourly basis for every U.S. county. We vision this approach as a first effort to provide a prediction system to support emergency preparedness and response to flash flood disasters over the conterminous U.S. It is recommended that the flash flood disaster science community and practitioners conduct data collection with more details for the life-threatening scene, and at finer resolutions to support modeling of local temporal and spatial complexities associated with human losses from flash flooding in the future.

Applying the "safe place, safe person, safe systems" framework to improve OHS management: a new integrated approach

Makin, Anne-Marie, Safety Science, Faculty of Science, UNSW January 2009 (has links)
A new model was developed to enhance the understanding of the full context of work associated hazards, to explore the connection between OHS performance and a systematic approach to safety, and to simplify approaches to OHS management. This Safe Place, Safe Person, Safe Systems model was derived from the literature and used as the basis for the development of a framework, consisting of 60 elements which was transformed into an assessment tool. This assessment tool was trialled with a pilot study on a medium sized manufacturing plant in the plastics industry, and the tool and Preliminary Report peer reviewed by an expert panel using the Nominal Group Technique. After refinements were made to the assessment tool it was applied to eight case studies that were drawn from advertisements. This qualitative study consisted of two parts: firstly the assessment using the Safe Place, Safe Person, Safe Systems framework; and secondly a controlled self assessment exercise to target improvements to three of the elements over a period of four months. The study illustrated that the Safe Place, Safe Person, Safe Systems framework could be successfully applied in a range of industries to promote OHS improvements and to provide a systematic, planned approach to fulfilling OHS responsibilities. The application of this framework highlighted that: there is a need for further education on the correct application of the risk assessment process and the responsibilities owed to contractors; techniques such as dynamic risk assessments are more suitable where the place of work is variable and hazards are unpredictable; more focus is needed on the appropriate management of hazardous substances with long term health consequences; and that the level of formality invoked for treating hazards does not necessarily equate to improved risk reduction outcomes. The Safe Place, Safe Person, Safe Systems framework was found to be applicable to small, medium and large organisations provided the assessment was scoped to a small division of relatively homogeneous activity to ensure a more representative hazard profile. This approach has provided a way forward to simplify OHS management and also offers practical direction for implementing a targeted OHS improvement program.

Dynamic Risk Management in Information Security : A socio-technical approach to mitigate cyber threats in the financial sector / Dynamisk riskhantering inom informationssäkerhet : Ett sociotekniskt tillvägagångssätt för att hantera cyberhot i den finansiella sektorn

Lundberg, Johan January 2020 (has links)
In the last decade, a new wave of socio-technical cyber threats has emerged that is targeting both the technical and social vulnerabilities of organizations and requires fast and efficient threat mitigations. Yet, it is still common that financial organizations rely on yearly reviewed risk management methodologies that are slow and static to mitigate the ever-changing cyber threats. The purpose of this research is to explore the field of Dynamic Risk Management in Information Security from a socio-technical perspective in order to mitigate both types of threats faster and dynamically to better suit the connected world we live in today. In this study, the Design Science Research methodology was utilized to create a Dynamic Information Security Risk Management model based on functionality requirements collected through interviews with professionals in the financial sector and structured literature studies. Finally, the constructed dynamic model was then evaluated in terms of its functionality and usability. The results of the evaluation showed that the finalized dynamic risk management model has great potential to mitigate both social and technical cyber threats in a dynamic fashion. / Under senaste decenniet har en ny våg av sociotekniska cyberhot uppkommit som är riktade både mot de sociala och tekniska sårbarheterna hos organisationer. Dessa hot kräver snabba och effektiva hotreduceringar, dock är det fortfarande vanligt att finansiella organisationer förlitar sig på årligen granskade riskhanteringsmetoder som både är långsamma och statiska för att mildra de ständigt föränderliga cyberhoten. Syftet med denna forskning är att undersöka området för dynamisk riskhantering inom informationssäkerhet ur ett sociotekniskt perspektiv, med målsättningen att snabbare och dynamiskt kunna mildra bägge typerna av hot för att bättre passa dagens uppkopplade värld.  I studien användes Design Science Research för att skapa en dynamisk riskhanteringsmodell med syfte att hantera sociotekniska cyberhot mot informationssäkerheten. Riskhanteringsmodellen är baserad på funktionskrav insamlade genom intervjuer med yrkesverksamma inom finanssektorn, samt strukturerade litteraturstudier.  Avslutningsvis utvärderades den konstruerade dynamiska modellen avseende dess funktionalitet och användbarhet. Resultaten av utvärderingen påvisade att den slutgiltiga dynamiska riskhanteringsmodellen har en stor potential att mitigera både sociala och tekniska cyberhot på ett dynamiskt sätt.
