Sweden's Path to NATO: Impacts on Security and Risk Perceptions : A comprehensive analysis based on the tactical, operative and strategic dimensions of Gotland / Sveriges väg till NATO: Effekter på säkerhet och risk

Ostrander, Hannah, Johansson, Amanda January 2024 (has links)
This Bachelor's thesis examines the consequences of Sweden's NATO membership regarding its security and defence policy, with a particular focus on Gotland. Sweden's transition to NATO membership was motivated by escalating geopolitical tensions in Europe due to the conflict between Russia and Ukraine and especially in the Baltic Sea region. This study employs a qualitative approach, using semi-structured interviews with key stakeholders in Gotland's military and municipal sectors to assess the strategic, operational and tactical effects of NATO membership. The results indicate that although NATO membership strengthens Sweden's national defence and geopolitical position, its immediate tactical and operational effects on Gotland are limited. The ongoing military development in Gotland, which was initiated before NATO membership, continues to develop with additional support and cooperation opportunities provided by the alliance. The research highlights the strategic necessity of NATO membership for Sweden, which provides increased security guarantees and adapts to broader geopolitical goals. However, the full extent of NATO's influence on Gotland's military development and societal impact requires further investigation given the recency of Sweden's membership on March 7, 2024. This thesis contributes to the academic discussion of geopolitical alliances and provides insights for policy makers in strategic planning and implementation.

The molecular basis of the plant-pathogen interaction of potato and Rhizoctonia solani

Genzel, Franziska 10 September 2018 (has links)
Die Kartoffel, eines der wichtigsten Nahrungsmittel weltweit, wird unter anderem von dem Erreger Rhizoctonia solani Kühn befallen. Durch dieses Pathogen hervorgerufene Qualitäts- und Ertragsverminderungen können zu erheblichen ökonomischen Verlusten führen. Da derzeitig verfügbare Bekämpfungsmaßnahmen nur eine eingeschränkte Effektivität aufzeigen, sind alternative Bekämpfungsstrategien dringend notwendig. Der Einsatz resistenter Sorten stellt eine effektive, umweltfreundliche Alternative dar, jedoch ist derzeit nur wenig über die der Resistenz der Kartoffel gegenüber R. solani zugrundeliegenden Mechanismen bekannt. Ziel dieser Arbeit war es, Merkmale aufzufinden, die mit einer erhöhten Feldresistenz der Kartoffel gegenüber R. solani korrelieren und zukünftig als Marker in der Züchtung zur Einschätzung des Resistenzgrads von Sorten genutzt werden können. Auf der Grundlage von Feldversuchen wurden zwei Kartoffelgenotypen mit einem unterschiedlichen Grad der Feldresistenz gegenüber R. solani für vergleichende molekularbiologische und biochemische Analysen ausgewählt. Die Analyse des Expressionsniveaus ausgewählter Abwehrgene zeigte, dass die Kartoffelsorte mit geringerer Anfälligkeit ein konstitutiv höheres Expressionsniveau aufweist als die Sorte mit einer höheren Anfälligkeit. Im Gegensatz zur stärker anfälligen Sorte wurde in Wurzeln und Stängeln der weniger anfälligen Sorte kein erhöhtes Expressionsniveau der Abwehrgene infolge der Infektion mit R. solani festgestellt. Zudem wies die weniger anfällige Sorte höhere Gehalte an α-Chaconin and α-Solanin sowie Nicotiflorin auf. Anhand von in vitro Untersuchungen wurde ein wachstumshemmender Effekt dieser Komponenten auf R. solani festgestellt. Weiterhin wurde ein geringerer Gehalt an R. solani-DNA in den Wurzeln der weniger anfälligen Sorte determiniert. Demnach scheint eine geringere Anfälligkeit der Kartoffel gegenüber diesem Erreger mit einer höheren, präformierten pflanzlichen Immunabwehr korreliert zu sein. / Potato, the fourth most important food crop worldwide, is also target of many pests and microbial pathogens including the fungus Rhizoctonia solani Kühn. The infection of potato with this pathogen leads to considerable economic losses. The soil-borne nature, the formation of melanised sclerotia, and the limited efficacy of fungicides impair the control of this pathogen and strengthen the necessity for alternative control measures. A very effective alternative is the use of resistant cultivars. Quantitative differences in the degree of resistance of potato to R. solani have been repeatedly observed in the field. However, until now there is no information available regarding the underlying mechanisms contributing to the resistance level. This thesis aimed at revealing mechanisms in potato which contribute to the manifestation of a certain degree of field resistance to R. solani. Based on the screening of various potato genotypes in field trials, two potato cultivars distinctly differing in the level of resistance to R. solani were selected for further molecular and biochemical analyses. The cultivar with a higher degree of resistance showed higher constitutive expression of defence-related genes. In contrast to the less resistant cultivar, no distinct increase of the defence-gene expression level was detectable upon pathogen infection in this cultivar. Moreover, contents of the glycoalkaloids α-chaconine and α-solanine and of the flavonol nicotiflorin were higher compared to the less resistant cultivar. Using in vitro culture tests, a growth-reducing effect of these compounds on R. solani was confirmed. Concluding, a higher resistance of potato cultivars to R. solani seems to be related to a higher expression level of defence-related genes and to a higher content of plant secondary metabolites. This enhanced constitutive defence level resulted in a lower pathogen colonisation of the plant, thus contributing to a reduced disease severity in the field.

Transformation of a service organisation through participatory action research

Harrison, Elaine Sonet 11 1900 (has links)
The research aimed to pro-activeiy embark in an internal transformation process, in order to improve efficiency of the Social Work Department of Gauteng Medical Command of the South African Military Health Service. Participatory action research as a qualitative research design was- used. The intervention identification process was implemented as a problem-solving technique to direct the process of transformation-change. The research was conducted by a research group often social workers from the South African National Defence Force. The results of the research were the implementation of interventions on identified systems, namely the service delivery system and the performance management system of the Social Work Department of Gauteng Medical Command. The use of particpatorv action research as a process to address problems in an organisation was confirmed. The contribution of the participatory action process to process outcomes, such as empowerment and learning, was also indicated in the findings. / Social Work / MA(SS) (Mental Health)

Prevention of theft of official vehicles of the South African National Defence Force (SANDF) in the Gauteng Province

Mathebula, Esewu Mxolisi 29 September 2014 (has links)
The South African National Defence Force (SANDF) was formed in 1994 after the integration of different “defence forces” into one large force. The sole existence of the SANDF is to protect the borders of the Republic of South Africa and its inhabitants. Resources such as vehicles make it easier for the SANDF to conduct mobile patrols and other operations to ensure that the organisation is always combat-ready. Motor vehicle theft is a crime that affects both individual citizens and organisations in South Africa; the SANDF is not immune to the crime. Many SANDF motor vehicles are stolen almost every day, and in most cases, these vehicles are taken without a trace. While there are security measures in place aimed at preventing theft of SANDF vehicles but these methods have proven futile. A literature review formed the basis of the study. Once the main theory and ideologies were identified, unstructured interviews were undertaken to gather information from various stakeholders. Observations were also conducted to determine behavioural patterns within military bases/units with regard to the parking of SANDF vehicles, even when the vehicles were parked in urban settings. Essentially, there is a problem regarding the security of SANDF vehicles and also the security within military bases / units. This study indicated that the SANDF loses vast amounts of money due to motor vehicle theft in Gauteng Province. The findings also revealed that the current vehicle security measures are outdated, ineffective and inadequate in preventing SANDF vehicles from being stolen. The recommendations are that the SANDF must invest more of its budget on vehicle security, rather than continuing with fruitless and monetary expenditure by conducting Board of Inquiries (BOI) or lengthy investigations in an attempt to relocate stolen vehicles or to determine how a particular vehicle was stolen. The SANDF requires a comprehensive system that should prevent the theft of its vehicles, as well as curbing the misuse of vehicles which ultimately renders SANDF vehicles as easy targets. / Police Practice / M.

Knowledge management practices at the Department of Defence in South Africa

Ramohlale, Molatelo Paul 06 1900 (has links)
Defence organisations have now significantly developed and in the process they have applied various measures to sustain their progresses and encourage innovation. One of those measures is by embarking on KM programs. KM in military is seen as a strategic approach to achieving defense objectives by leveraging the value of collective knowledge through the process of creating, gathering, organizing, sharing and transferring knowledge into action. It is through proper knowledge management practices that an organisation embraces and manages its knowledge generation, knowledge acquisition, knowledge organisation, knowledge storage, transfer, knowledge sharing, and knowledge retention. The purpose of this study was to investigate knowledge management practices in the Department of Defence (RSA). The objective of the study was to find out how the department appreciates, understands, interprets and handles its knowledge. This study employed triangulation method to present trustworthiness of both qualitative and quantitative research approaches using positivist research design. Questionnaires, interviews and document analysis were employed to collect data. In order to arrive at the number of participants who received the questionnaires, a probability sampling method called stratified random sampling was used as well as purposive sampling. When setting up a study, it was essential to review the research identified in the literature review and to determine whether there is anything relevant to the research design of the proposed study. The study found that knowledge management was hardly understood generally in the department and was not an approach used and institutionalised for the benefit of the organisation. However there was embedded knowledge management appreciation from a few staff members in the department, only managing their own knowledge regarding learning, capturing and storage. Additionally there is a significant number of staff members who believe knowledge management is a way to go in the future and strongly believe their Defence Department needs to adopt a comprehensive and inclusive KM approach. / Information Science / M.A. (Information Science)

Pulling back the curtain : an examination of the English Defence League and their use of Facebook

Reynolds, Teddy January 2015 (has links)
As social media becomes an integral part of our daily lives, and groups seek to utilize this medium to facilitate activism, understanding the nature of these communications and the impact of the content on the individual user becomes a valid area of interest. When one then considers that extremist and terrorist groups have found social media to be an inexpensive and effective means for communication, radicalization, recruitment and member mobilization, the need for this understanding becomes critical. This research seeks to provide just such an understanding in its examination of Far-Right English Defence League and their use of Facebook during a period of increased activism and online growth. Important elements of this work include an understanding of the legal and ethical issues surrounding the collection of online content, particularly in extremist environments; the role of traditional media in their coverage of the group and whether the comments of the members reflect the group's mission statement of the characterization of traditional media; the ability to enhance data segregation and analysis through the development and use of specialized software; and most importantly the findings from the data analysis. Contained within these findings is an understanding of the intricacies of online participation in extremist social media. These include insights into overall traffic generation, the use of links within communications and their impact on the member traffic, and how the group narrative put forth by the administrator is reflected in the dialogue of the users. The most important finding was an understanding of individual user participation within the group and how, even with such an inexpensive and pervasive media outlet, activist groups still struggle to overcome the problem of participation. That this knowledge can be applied in a meaningful way in counter extremist and counter terrorism efforts was an interesting and satisfying development.

The once and future Army : an organizational, political and social history of the Citizen Military Forces, 1947-1974

McCarthy, Dayton S., History, Australian Defence Force Academy, UNSW January 1997 (has links)
This thesis examines the Citizen Military Forces (CMF) from 1947 until it ceased to exist under that name with the release of the report of the Millar Inquiry in 1974. This thesis examines three broad areas: the organizational changes that the CMF adopted or had imposed upon it; the political decision-making surrounding the CMF; and a social analysis of the CMF which questions the viability and validity of a number of the CMF???s long held precepts. The thesis will show that the majority of circumstances and decisions surrounding the CMF were beyond its control. For example, the CMF could not change the prevailing military thought of the post-war period which emphasized increasingly the role of smaller, professional, readily-available armies. The first three chapters recount the CMF???s ???heyday??? in which the Army, assisted by National Service after 1950, was based around it and its influence at the highest levels was strongest. The next two chapters chronicle the background to Australia???s adoption of the ???Pentropic??? organization and the repercussions this had on the CMF. Chapters Six and Seven examine the consequences of the introduction of a second compulsory service scheme and the concomitant result which precluded the CMF from operational service in Vietnam. Chapters Eight and Nine deal with the Millar Inquiry, which offered the CMF a new hope, but in some regards, brought forth little beneficial gains for the CMF. The final chapters analyze some of the characteristics unique to the CMF, such as territorial affiliation, high turnover rates amongst the rank and file and the concept of the ???brilliant amateur???. This thesis concludes that, despite the mixed performance of the CMF, there is still a place for the citizen soldier in contemporary warfare, but far more consideration at the highest political and military levels must be given to the peculiar and difficult, but by no means insurmountable, problems citizen soldiering encounters in Australia.

Computer Aided Text Analysis in Personnel Selection

Garrad, Mark, n/a January 2004 (has links)
This program of research was aimed at investigating a novel application of computer aided text analysis (CATA). To date, CATA has been used in a wide variety of disciplines, including Psychology, but never in the area of personnel selection. Traditional personnel selection techniques have met with limited success in the prediction of costly training failures for some occupational groups such as pilot and air traffic controller. Accordingly, the overall purpose of this thesis was to assess the validity of linguistic style to select personnel. Several studies were used to examine the structure of language in a personnel selection setting; the relationship between linguistic style and the individual differences dimensions of ability, personality and vocational interests; the validity of linguistic style as a personnel selection tool and the differences in linguistic style across occupational groups. The participants for the studies contained in this thesis consisted of a group of 810 Royal Australian Air Force Pilot, Air Traffic Control and Air Defence Officer trainees. The results partially supported two of the eight hypotheses; the other six hypotheses were supported. The structure of the linguistic style measure was found to be different in this study compared with the structure found in previous research. Linguistic style was found to be unrelated to ability or vocational interests, although some overlap was found between linguistic style and the measure of personality. In terms of personnel selection validity, linguistic style was found to relate to the outcome of training for the occupations of Pilot, Air Traffic Control and Air Defence Officer. Linguistic style also demonstrated incremental validity beyond traditional ability and selection interview measures. The findings are discussed in light of the Five Factor Theory of Personality, and motivational theory and a modified spreading activation network model of semantic memory and knowledge. A general conclusion is drawn that the analysis of linguistic style is a promising new tool in the area of personnel selection.

The Killing of Osama bin Laden, Was it Lawful?

Elfström, Amanda January 2012 (has links)
The main purpose of this work is to investigate if the US ́s killing of Osama bin Laden on 2 May 2011 in Abbottabad in Pakistan was lawful. The background to the killing is what happened on 11 September 2001 when four US airplanes were hijacked and crashed into World Trade Center and Pentagon. Al Qaeda, a terrorist organisation led by Osama bin Laden, was immediately suspected for the attacks, which led to the starting point of the US ́s ‘global war on terror’. This work tries to give a short brief on ‘global war on terror’ and answer if there is a global war on terror and/or if a new category of war is needed. In order to get an answer to the main question of this work I had to investigate if US is in an international armed conflict or in a non-international armed conflict with Al Qaida. Another important question to investigate is if an armed conflict in one State can spill over to another State and still be consider as an armed conflict. Other important questions to answer are, if Osama bin Laden was a legitimate target under international humanitarian law, if he was a civilian or if he had a continuous combat function and what level of participation in hostilities he had? Not less important is also to investigate if human rights law is applicable when Osama bin Laden was killed, especially the fundamental right to life. Lastly I end my investigation with a quick review of the laws of jus ad bellum in order to get an answer if US had a right to resort to force in Pakistan. My conclusion is that the US was not involved in an armed conflict with al Qaeda in Pakistan where the killing took place. The conflict between the US and al Qaeda in Afghanistan is to be categorised as a non-international conflict. This conflict cannot be described as a conflict that has spilled over to Abbottabad where Osama bin Laden was killed. All people, including Osama bin Laden, has a right to life. Because of lack of information on what happened in Abbottabad when Osama bin Laden was killed it is impossible to give a clear legal answer if the US had the right to kill him. It could be lawful, but it could also be considered as a crime against international human rights law.
