Technical means deployed to serve the LID (defensive cyber warfare) in the French Armed Forces
No full textAt the Ministry of Armed Forces, the LID (defensive cyber warfare) includes all actions, technical and non- technical, conducted in response to a risk, threat or cyber attack in order to preserve our freedom of action. However, it remains to be determined: what technical means can be deployed to serve the LID and how is it developed? This question will be the one studied throughout my thesis.
MTLID’s mission (LID technical means) is to provide the technical means of defensive cyber warfare allowing the technical chain to carry out the surveillance of systems. The objective is to protect systems from cyber attacks. It is also the first increment of the LID federation. Data collection is the only interface between the system to be monitored (SAS) and the MTLID System. The implementation of LID monitoring is based on the collection and exploitation of information provided by a SAS. The Local Monitoring System (ML) is defined as a set of resources deployed to supervise a system perimeter that may concern one or several SAS. An ML is composed of probes and dedicated processing means. The monitoring of the SAS connected to the local means is carried out from the following data sources:
• Data from MTLID capabilities: probes from the ML interfacing with the SAS.
• Data collected from the SAS: "raw" logs returned by the SAS, including data from probes deployed by the SAS, which can be processed (aggregation/correlation) and potentially the collection of enrichment data in the form of text files.
• If necessary, data from third-party capabilities (in this case, the information may come from a connection other than the SAS-ML connection). This additional supervision capability is only possible when collecting data from the SAS (raw logs and enrichment data)
Analysis of the Presence of Styrene in paperboard
Get PDFIn this work, the presence of styrene in paperboard was studied. Styrene is used in the production of styrene-acrylate (SA) and styrene-butadiene (SB) latexes. SA- and SB-latexes are the most common binders used in the coating of paper and paperboard. Pigment coating with latex can improve the appearance and printability of the product, and dispersion coating can additionally bring a barrier property to the surface, e.g., grease resistance, water resistance, or air permeability. If some chemicals in the food contact material may transfer to the food, it is called migration. Currently, styrene can be used as a monomer or other starting material in food contact materials without a set migration limit. The European Commission is currently evaluating the possible establishment of a migration limit for styrene into food. Styrene may possibly be a genotoxic compound. Since styrene is a volatile organic compound, it was studied with a headspace gas chromatography, based on the method used in Metsä Board Corporation, for which this work was done. All the results are clearly below the considered possible specific migration limit. However, the method was not suitable for quantifying styrene at these concentrations. The aim of the study was to determine the amount of residual styrene in paperboard samples and to test how time, temperature and UV light affect the amount of residual styrene. The results show that the amount of residual styrene decreases over time, but UV light has insignificant effect on the amount of residual styrene
Ignorance is bliss? Information and risk on crowdfunding platforms
No full textThis research examines the determinants of project success on crowdfunding platforms within a competitive context. We focus on the specific horizontal attributes of the project–attributes that do not affect the project returns but over which investors may have heterogeneous preferences–and on the project returns’ risk level. We run a laboratory experiment with several set-ups, where multiple projects compete for funding simultaneously and where potential investors operate in a quasi-continuous time. We find the horizontal attributes’ information affects project selection, while the risk level of the project returns affects the amount of collected funding.peerReviewe
CSR-kommunikation under kritiska händelser : En kvalitativ studie av H&M:s CSR-kommunikation under covid-19-pandemin
No full textDuring the Covid-19 pandemic, multiple companies decided not to pay for the ordered or made clothes. This led to garment workers not receiving their salaries. From a CSR perspective, this is going against human rights since various workers starved because of the actions from companies. While most companies later promised to pay up for the orders, their reputations had shifted negatively. Companies can regain trust through CSR communication. Currently several media channels open opportunities for companies to communicate their actions.
This study aims to understand how these critical events affect companies’ reputations and how their CSR communication through annual sustainability reports and social media affects the stakeholder’s perception of the company. The research was conducted by following H&M’s actions and CSR communication through annual sustainability reports and Instagram before, during, and after the Covid-19 pandemic for five years. The derived material was analyzed with a thematic analysis method. By dividing the results into separate themes, the material was implemented to answer the research questions.
The theoretical framework was built up by reading through earlier studies of CSR communication, reputation, and associated with critical events. CSR in fast fashion was furthermore investigated to understand the occurring situation in the fast fashion industry.
The results show that companies should have transparent communication. Although dialogical communication is recommended, practical actions are the most crucial for regaining reputation after critical events.
Social media and annual reports are effective ways to reach stakeholders. Through transparent communication, the company gains trust. Taking fast positive actions in the criticized events and communicating these positive actions through reports or social media has an positive impact on stakeholders. To be able to take fast action, companies must be aware of the criticized topics, and by taking action, stakeholders feel that the company listened to them.
The research confirmed that previous neutral and positive attitudes impact future attitudes even after critical events. People forget quickly negative events if the company takes action toward improvements

Get PDFSkoltrötthet och skolengagemang bland elever i årskurs 7–9
Get PDFTidigare forskning visar att det finns en koppling mellan skoltrötthet och skolengagemang och att dessa fenomen har ett samband med elevens välbefinnande, studieframgång och skolfrånvaro. Lärarna och undervisningen har en betydande roll för att förebygga elevers skoltrötthet och öka elevers skolengagemang. Tidigare studier visar även att skoltrötthet är vanligare bland flickor än pojkar medan det inte finns några entydiga resultat för könsskillnader gällande skolengagemang. Syftet med avhandlingen är att undersöka utvecklingen av skoltrötthet och skolengagemang bland elever i årskurs 7–9. Utifrån avhandlingens syfte har tre forskningsfrågor formulerats:
1. Hur utvecklas skoltrötthet bland elever i årskurs 7–9?
2. Hur utvecklas skolengagemang bland elever i årskurs 7–9?
3. Hur skiljer sig utvecklingen av skoltrötthet och skolengagemang mellan könen?
Avhandlingen är en del av projketet FRAM, Ungdomars välbefinnande och kunskap i framtidens samhälle. I projektet deltog elever ur fem högstadieskolor i Svenskfinland och data samlades in hösten 2016 och våren 2019. Samplet i denna avhandling består av 612 respondenter. Avhandlingen utgår ifrån en kvantitativ forskningsansats och analysmetoderna som genomförts är beroende grupps t-test, oberoende grupps t-test och variansanalys med upprepade mätningar.
Resultatet visar att det finns statistiskt signifikanta skillnader i utvecklingen av skoltrötthet där skoltrötthet ökar från åk 7 till åk 9. Statistiskt signifikanta skillnader kunde även hittas gällande skoltrötthet mellan könen där flickor har ett högre medelvärde. Gällande utvecklingen av skolengagemang hittades statistiskt signifikanta skillnader där skolengagemang minskar från åk 7 till åk 9 medan inga statistiskt signifikanta skillnader kunde hittas mellan könen gällande skolengagemang.
Både tidigare forskning och resultaten för denna avhandling visar att skoltrötthet ökar och skolengagemang minskar bland elever i årskurs 7–9. Därför är det viktigt att i ett tidigt skede identifiera elever som visar tecken på skoltrötthet och upprätthålla elevers skolengagemang för att skapa de bästa förutsättningarna för elevers lärande och välbefinnande
The connection between well-being and school performance : An empirical study of teachers' work with well-being and relationships to promote students' school performance
No full textGenomförda Pisa-undersökningar påvisar att ungdomars välbefinnande blir allt sämre, vilket även syns bland finländska ungdomars svar i enkäten Hälsa i skolan som genomförs av Institutet för hälsa och välfärd. Syftet med vår avhandling är ta reda på hur lärare ser på relationen till sina elever, hur de arbetar för att främja elevernas välbefinnande samt hur lärare anser att elevens psykiska hälsa påverkar skolprestationerna i skolan. Utifrån syftet med studien har tre forskningsfrågor utarbetats:
1. Hur arbetar lärare för att skapa trygghet och välbefinnande hos sina elever?
2. På vilket sätt anser lärare att elevens psykiska hälsa syns i skolresultaten?
3. Hur resonerar lärare kring den sociala kontexten i relation till elevers välbefinnande?
I studien används en fenomenologisk forskningsmetod, eftersom forskarna är intresserade av att ta reda på verksamma lärares personliga erfarenheter av välbefinnande och skolprestationer. Sju informanter har intervjuats genom semistrukturerade intervjuer och studien är således av kvalitativ forskningsansats. Insamlade data analyserades genom meningskategorisering och presenteras i form av narrativ. Resultaten redovisas med hjälp av kategorier som kunnat urskiljas vid analysen och presenteras genom citat från intervjuerna.
Resultaten visar att lärare definierar en god psykisk hälsa som att eleven känner sig trygg och vill vara i skolan. För att främja välbefinnandet hos eleverna strävar lärare efter att göra eleverna delaktiga i skolarbetet, skapa ändamålsenliga lokaler och stärka sammanhållningen inom gruppen. Resultaten påvisar att lärare anser att en god psykisk hälsa hos eleven leder till bättre skolprestationer. Lärare anser att en god relation till eleven kan bidra till välbefinnande och bättre skolprestationer
Journalistisk objektivitet – Vad kan det innebära att omvärlden påverkas av språket i nyhetsrapporteringen?
Get PDFI avhandlingen behandlas två exempel av händelser som rapporterades av olika nyhetsmedier. Syftet är att komma fram till hur det kan se ut när språket i nyhetsrapporteringen inte anses vara objektiv och vad detta kan ha för möjliga följder. Ämnet undersöks från ett filosofiskt perspektiv med hjälp av J.L. Austins och Stanley Cavells språkfilosofiska teorier
Acid Attacks against Women in Pakistan : A Literature Study
Get PDFAim: The study aimed to investigate acid attacks against women in Pakistan. The study describes the historical, social, cultural, and political context in which this type of gender violence has developed and provides implications.
Method: A literature review was applied. This involved reviewing the literature, both qualitative and quantitative studies, case studies, and reports by governmental and non-governmental organizations.
Results: Every year, hundreds of acid attacks happen to women in Pakistan. The acid violence has deep roots in the country's history, social norms, and cultural practices. Briefly, in a male-dominated society, women seeking education or employment outside the home are often targeted with violence. Victims not only suffer from physical and psychological trauma, but they also face social stigma and exclusion.
Conclusions: Education campaigns targeting men and boys could raise awareness. Survivors require social, psychological, and financial assistance. Policymakers need to develop their technical competency on this issue
