Olsson, Sanna, e Isabella Hultberg. "Cybersäkerhet - Att stärka den svaga länken : En flerfallsstudie om hur formella och informella styrmedel förebygger interna cyberhot i banksektorn". Thesis, Linköpings universitet, Institutionen för ekonomisk och industriell utveckling, 2021. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-176804.
Background: Banks play an important role in society and have since the increasing digitalization been particularly exposed to cyber threats. At the same time, the bank's operations are largely based on maintaining trust of its customers, and therefore it is of great importance for banks to have a high level of cyber security. Above all, internal cyber threats in the form of human error constitute one of the greatest risks to banks' security work today. Therefore, it is interesting to investigate how banks work to mitigate internal cyber threats through formal and informal management controls. Purpose: This study aims to contribute to an increased understanding of how banks use formal and informal management control to mitigate internal cyber threats in the workplace. Methodology: This study adopts a hermeneutic perspective and uses qualitative method. Furthermore, an abductive approach has shaped the essay. The purpose and research questions have been answered through a multiple case study of four different banks in Sweden. The empirical material has been obtained with the help of interviews with representatives from each bank who work with security. Conclusion: To prevent internal cyber threats, banks work with rules which global standards and the company’s culture help design. We have noted that competence and awareness in cyber security is something that is valued highly. To strengthen the competence banks invest large resources in training. Making the idea of safety a natural part of employees' daily work has above all been emphasized by, at the same time as cultural development is largely done passively as the strong regulations shape culture. Informal dialogues, however, increase awareness and thus strengthen culture. Finally, we have identified that all the management controls mentioned above affect each other. Therefore, it is important to have a holistic approach to the governance work regarding cyber security.

The aim of this thesis was to study the use of Collaborative Virtual Environments (CVE) for the analysis of the state of security of computer systems, also called Cyber Situational Awareness (CSA). After studying CSA’s models and tools, we have had the opportunity to visit the Security Operations Centers (SOCs) of four industrial partners of the CyberCNI chair, in order to better understand the needs and expectations of cyber analysts. These visits were made as part of a collaborative activity analysis protocol and have allowed us to propose a model, the 3D Cyber-COP. Based on this model and a model of the WannaCry ransomware, we have developed a CVE and a simplified scenario engine that allows users to design their own alert analysis scenarios. We have also performed a usability evaluation of a virtual environment for alert analysis, with a panel of novice users

Det övergripande syftet med detta projekt har varit att bidra till en effektiviserad digitalisering och individualisering. Målet för projektet har varit att undersöka alternativa tekniska lösningar för att göra egna tillägg i CMS:et SiteVision. Tillägg vars uppgift består i att hämta data från ett externt API (Office 365) som kräver autentisering med OAuth 2.0. Vidare har de alternativa tekniska lösningarna värderats och jämförts. Jämförelsen har gjorts utifrån kriterier som tagits fram genom intervjuer med utvecklare på ett IT-konsultbolag. Inom projektet har ett tillämpat exempel (POC) skapats för att visa exempel på hur tekniken kan användas. I detta exempel har Java Portlets använts för att implementera ovanstående funktionalitet. Även WebApps i SiteVision har studerats då den tekniken utgör ett alternativ till Java Portlets. Undersökningen visar att det är fullt möjligt att skapa ett eget tillägg i SiteVision som genomför autentisering med OAuth 2.0 och sedan använda denna för att hämta data från ett externt API. Resultaten från jämförelsen mellan de två olika teknikerna Java Portlets och WebApps visar att det finns för- och nackdelar med respektive teknik. Båda alternativen framstår som jämstarka i jämförelsen. De individuella omständigheterna kring ett framtida användande bör fälla avgörandet för vilken teknik som väljs.
Nicolas, Clémence. "Polymérisation par ouverture de cycle par métathèse de monomères antioxydants en vue de l’amélioration des propriétés de matériaux à base de polydicyclopentadiène". Thesis, Le Mans, 2019. http://cyberdoc-int.univ-lemans.fr/Theses/2019/2019LEMA1025.pdf.
Polydicyclopentadiene (PDCPD) is a thermoset polymer material with particularly interesting properties: it combines high impact resistance, good resistance to chemical corrosion and high heat deflection temperature. These features allow to consider its use in extreme conditions as a pipeline joint for the extraction of offshore oil. However, its use is limited by its oxidation sensibility because of the presence of double bonds in its backbone. Adding additives to PDCPD materials is needed to limit the PDCPD degradation by inhibition of oxidation. However, conventional additives undergo diffusion that decreases their long-term efficacy because of their low molar mass. To address this issue, two strategies were studied: (1) the grafting of additives with antioxidant properties within the backbone by ring-opening metathesis polymerization (ROMP) of dicyclopentadiene (DCPD) with norbornenyl antioxidant-functionalized comonomers; (2) ROMP of these monomers to prepare additives with higher molar masses, which are less likely to undergo diffusion. The original materials obtained from industrial formulations based on PDCPD and the synthesized monomers and polymers have shown a better stability than the formulations based on commercially available additives, confirming the relevance of the strategies implemented in this thesis work
Clavier, Batiste. "Synthèse, caractérisations et évaluation de l'activité bactéricide de composés inorganiques à base de cuivre". Thesis, Le Mans, 2019. http://cyberdoc-int.univ-lemans.fr/Theses/2019/2019LEMA1041.pdf.
Bacterial pathogens causing healthcare-associated-infections pose ongoing and increasing challenges to care facilities. In France, Escherichia coli and Staphylococcus aureus are responsible for more than 40% of these infections. Due to the permanent adaptation of these bacteria to new antibiotics placed on the market, complementary solutions must be found. One of these solutions proposed in this thesis work aims to exacerbate performances of known bactericidal materials (synergistic effect) or to provide bactericidal properties to non-active compounds by partially substituting magnesium ions by cupric ones or vice versa. New solid solutions were thus highlighted. Solid state reaction, co-precipitation, hydrothermal routes or mechanosynthesis were employed to synthesize micrometer-sized or nanometer-sized particles of those desired compounds. When obtained, X-Ray Diffraction, electron microscopies, dinitrogen adsorption, IR/UV-visible spectroscopies, ThermoGravimetric Analysis-Mass Spectrometry and Atomic Emission Spectroscopy are used to determine the nature, composition and size of those particles as well as their stability in water or CO2 rich atmosphere. The evaluation of bactericidal properties in water and at 20°C showed that the partial substitution of magnesium by copper enhances the activity of compounds both in terms of magnitude and kinetics. These increased performances are not necessarily related to the copper content in the active compound
Larmier, Salomé. "Génération de fluides, migration et fracturation au sein des roches mères : cas de la formation de la Vaca Muerta, bassin de Neuquén, Argentine". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1009.pdf.
Natural hydraulic fractures caused by fluid overpressure phenomena are common in source rocks. They generally materialize in calcite veins more commonly known as "beef". The study of these veins makes it possible to better constrain the tectonic and thermal history of the basin. Moreover, understanding their spatial distribution is a key parameter for unconventional oil exploitation, as the beef plays an important role on the development of induced hydraulic fracturing. This work presents a multidisciplinary approach in the field of geosciences to constrain the timing, distribution, morphology and origin of the fluid feeding the beef. The case study is from the Vaca Muerta formation, Neuquén basin, Argentina. The results of studies carried out on sediment cores and outcrops showed that sedimentary heterogeneities, high TOC values, rock maturity and compressive tectonic stresses controlled the frequency and thickness of the beef. Thus, they become markers of rock maturity. Beefs have a 3D morphology that varies according to the surrounding rock. Petrographic observations have shown that they record the contemporary and posterior deformation of their opening. The fluids that feed these fractures evolve over time and change locally according to the mineralogical composition of the surrounding rock and temperature. To conclude, the beefs are mechanically set in place by the action of fluid pressure and/or compressive tectonic stress, at the maximum burial and at the beginning of the exhumation of the basin
Bouzid, Salah Eddine. "Optimisation multicritères des performances de réseau d’objets communicants par méta-heuristiques hybrides et apprentissage par renforcement". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1026.pdf.
The deployment of Communicating Things Networks (CTNs), with continuously increasing densities, needs to be optimal in terms of quality of service, energy consumption and lifetime. Determining the optimal placement of the nodes of these networks, relative to the different quality criteria, is an NP-Hard problem. Faced to this NP-Hardness, especially for indoor environments, existing approaches focus on the optimization of one single objective while neglecting the other criteria, or adopt an expensive manual solution. Finding new approaches to solve this problem is required. Accordingly, in this thesis, we propose a new approach which automatically generates the deployment that guarantees optimality in terms of performance and robustness related to possible topological failures and instabilities. The proposed approach is based, on the first hand, on the modeling of the deployment problem as a multi-objective optimization problem under constraints, and its resolution using a hybrid algorithm combining genetic multi-objective optimization with weighted sum optimization and on the other hand, the integration of reinforcement learning to guarantee the optimization of energy consumption and the extending the network lifetime. To apply this approach, two tools are developed. A first called MOONGA (Multi-Objective Optimization of wireless Network approach based on Genetic Algorithm) which automatically generates the placement of nodes while optimizing the metrics that define the QoS of the CTN: connectivity, m-connectivity, coverage, k-coverage, coverage redundancy and cost. MOONGA tool considers constraints related to the architecture of the deployment space, the network topology, the specifies of the application and the preferences of the network designer. The second optimization tool is named R2LTO (Reinforcement Learning for Life-Time Optimization), which is a new routing protocol for CTNs, based on distributed reinforcement learning that allows to determine the optimal rooting path in order to guarantee energy-efficiency and to extend the network lifetime while maintaining the required QoS
Varela, Fernandez Dario. "Les réseaux hispanistes français au début du XXème siècle : coopérations savantes et relations culturelles, France-Espagne-Amériques (1890-1930)". Thesis, Le Mans, 2019. http://cyberdoc-int.univ-lemans.fr/Theses/2019/2019LEMA3012.pdf.
The purpose of this work is to study in an innovative way the origins of French Hispanism. A study of the first scholarly journals in thefield of Hispanism (Hispanic Journal, Bulletin Hispanic, Latin American Review) reveals how these companies operate and the role played by more than six hundred employees within the period 1890-1930. This information was cross-referenced both with the study ofpublications and with published and handwritten correspondence. 4,804 articles and reviews, 529 books and 1,712 letters exchangedbetween Hispanists were examined in 25 institutions in seven countries (France, Spain, Argentina, Chile, Colombia, Mexico, UnitedStates). These documents make it possible to build a prosopography of the actors and to lead an analysis of their networks, giving anoverview of the scholarly relationships and the importance of each person in the new field. The correspondence study also allows one toaccess the content of exchanges between French Hispanists and their European and American counterparts.This work highlights the interests of the different actors, their belonging to diverse groups, their motivations, their political ideas,agreements and disagreements when it comes to defining what a hispanist is. The thesis reveals that French Hispanism is at its origin afield where two academic poles (Bordeaux-Toulouse and Paris) and an extra-university center are opposed and trying to impose theirvision of the future of the domain
Javed, Fahim. "Auditor Gender and Audit Quality in a Joint Audit Setting". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA2003.pdf.
In the context of rapidly increasing interest of regulators, legislators and academic research in the identity of audit engagement partners, this dissertation explores French mandatory joint audit environment where firms preparing consolidated financial statements are jointly audited by two independent audit firms. The composition of joint audit partners may include same gender audit partners (two male, two female) or gender-diverse audit partners (one male and one female). This dissertation aims to examine whether gender-diverse audit partners provide higher audit quality compared with same gender audit partners. We argue that gender-diverse engagement partners are more likely to promote effective monitoring and collaborative behavior with regard to audit process and may positively influence audit quality. We investigate the issue of audit quality by examining input- and output-based measures, namely, audit fees and discretionary accruals. We use data on French listed firms and apply appropriate econometrical procedures to alleviate concerns about endogeneity issues. The empirical findings show that gender-diverse audit partners charge 11% audit fee premium and their clients exhibit lower levels of absolute and signed discretionary accruals. Collectively, we provide considerable evidence that gender-diverse audit partners produce higher-quality audits. In the aftermath of gender quota legislation, the current dissertation also examines whether gender profile of audit clients affect the selection/assignment of gender-diverse audit partners. Contrary to the gender similarity (homophily) argument—based on comprehensive analyses of client-partner gender alignments—we provide compelling evidence that that female directors appointed to monitoring positions on the board, compared to female inside directors, tend to select higher quality “auditor pairs” (i.e., gender-diverse engagement partners)
Malléjac, Matthieu. "Metamaterials with extreme properties for the control of acoustic waves". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1024.pdf.
Zero-index metamaterials, for which at least one of the effective parameters (density or dynamic compressibility for acoustics) vanishes, have received considerable attention in recent years. These materials have the particularity of inducing a considerable increase in the effective wavelength, thus offering numerous application possibilities, including, among others, propagation without phase change, acoustic hiding of diffusers, directivity control, etc. This PhD work focuses particularly on the near-zero effective density regime in acoustic metamaterials made of thin plates in air. Through an in-depth study of a periodic arrangement of thin elastic plates embedded in a waveguide, we have been able to explore analytically, numerically and experimentally some of the above effects. Particular attention is paid to the losses inherent to this type of system and their consequences on the expected behavior. We begin by studying numerically and experimentally observing a phase-change-free propagation through the metamaterial at a frequency in a stopband of the finite system. We then transpose the concept of photonic doping to acoustics. The addition of an impurity, here a well-chosen Helmholtz resonator, to the system allows to transform the regime of zero density into one where density and compressibility are simultaneously near zero. Thus, propagation without phase change is accompanied by a unitary transmission, due to the impedance matching of the system with the surrounding air. Finally, we study the possibility of performing acoustic hiding or masking of an object using the acoustic wavelength stretching offered by the zero density
Soltane, Marius. "Statistique asymptotique de certaines séries chronologiques à mémoire". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1027.pdf.
This thesis is devoted to asymptotic inferenre of differents chronological models driven by a noise with memory. In these models, the least squares estimator is not consistent and we consider other estimators. We begin by studying the almost-sureasymptotic properties of the maximum likelihood estimator of the autoregressive coefficient in an autoregressive process drivenby a stationary Gaussian noise. We then present a statistical procedure in order to detect a change of regime within this model,taking inspiration from the classic case driven by a strong white noise. Then we consider an autoregressive model where the coefficients are random and have a short memory. Here again, the least squares estimator is not consistent and we correct the previous statistic in order to correctly estimate the parameters of the model. Finally we study a new joint estimator of the Hurst exponent and the variance in a fractional Gaussian noise observed at high frequency whose qualities are comparable to the maximum likelihood estimator
Essassi, Khawla. "Développement et caractérisation statique et dynamique d'un composite sandwich à âme auxétique et à constituants naturels". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1025.pdf.
In recent years, bio-based composite materials have been used in different industrial sectors due to their environmental interests. The use of a biological matrix reinforced with vegetable fibers makes it possible to improve not only environmental protection but also mechanical performance. On the other hand, auxetic structures have emerged as a result of their high specific properties and especially their great energy absorption capacities. In this context, this study proposes to develop a composite sandwich material with a re-entrant honeycomb core and a purely natural constituent. In order to build this structure, the additive manufacturing method was used. First, the static tensile behavior of the skins is analyzed. The elastic characteristics of the printed specimens in different directions are determined. Subsequently, the mechanical properties of auxetic cores in tension and in compression as well as those of sandwiches in bending and indentation were developed. An analysis of damage mechanisms during indentation tests is performed using the acoustic emission technique. Then, experimental tests and analytical models were carried out to determine the fatigue behavior of the sandwiches. Finally, a study of the vibration behavior of the skin, cores and sandwiches is carried out using an experimental and numerical study by finite element. The contribution of each component in the global damping properties is discussed

Grasslands have been in decline since the 1970s but they can play a major role in the agroecological transition in view of the many assets they have to offer. However, their enhancement through grazing is difficult to implement and directly affects the expected benefits. In this respect, digital tools are being developed to optimise grazing management in the context of precision livestock farming, a concept based on the digital revolution. However, these tools remain marginal and their added value is generally poorly perceived by farmers. The behaviour and position of dairy cows should be used as a support for the development of these tools as they are potential indicators of the state of the resource on the paddock as well as the health and welfare of the animals. Embedded accelerometer and GPS sensors can automatically provide this information but appropriate analysis techniques are required. This thesis consists of (i) implementing a methodology to automatically collect the main behaviours of dairy cows on pasture using embedded accelerometer sensors and (ii) evaluating the potential of this methodology combined with position data to meet the envisaged applications. The methodological framework is based on raw acceleration processing techniques which have not been explored in the concerned community, associated with a combination of algorithms which uses the complementarity between machine learning methods and probabilistic models. Thus, it provides reliable prediction for a wide range of dairy cow behaviours at grazing. The proof of concept also demonstrates the potential of the methodology, combined with animal position data, to detect comfort disorders related to grazing conditions. This approach should therefore support the development of decision tools for optimising grazing management, thus providing a potential lever in the agroecological transition
Hodé, Romain. "Development of laser ultrasonic methods for the nondestructive evaluation of bonded aeronautical assemblies". Thesis, Le Mans, 2020. http://cyberdoc-int.univ-lemans.fr/Theses/2020/2020LEMA1030.pdf.
Currently, the weight lightening of aircraft structures is a major industrial issue in order to reduce engine fuel consumption and greenhouse gas emissions. Adhesive bonding addresses this need for lighter structures and has many advantages compared to more conventional techniques such as welding or riveting. Indeed, this method does not require the addition of rivets and allows to assemble composite materials with a high strength-to-weight ratio. However, to date there is no nondestructive evaluation (NDE) method to certify the mechanical strength of bonded assemblies. Overcoming this last technological limitation would enable a significant deployment of adhesive bonding in the industry. The objective of this thesis is to develop laser ultrasonic methods for the NDE of bonded assemblies. This optical technique to generate and detect ultrasound in a material has the advantage of being fully contactless. A semi-analytic model to simulate the propagation of laser generated waves in a multilayer structure is first presented. Then, two control methods which can experimentally discriminate between industrial bonds with and without defects are introduced. The first one concerns the resolution of an inverse problem using synthesized plane waves reflected from the bonding. The second one is based on the attenuation of local resonances of zero-group-velocity (ZGV) Lamb modes. These two methods allow the identification of quantitative parameters to distinguish structural bonds of different mechanical strengths

The diagnostic of sleep-disordered breathing requires the analysis of various signals obtained while recording sleep. The analysis is carried by a sleep specialist, which studies the patient's ventilation and, depending on the diagnostic tool used for the record, sleep stages. Sleep stage scoring is a complex and time-consuming task. Three diagnosis support algorithms dedicated to this task are presented in this thesis.The first one provides a wakefulness versus sleep classification, designed for a new diagnostic tool. It results in the ability to make a precise diagnosis of sleep apnea syndrome, at low cost.The second algorithm, based on electrophysiological channels, provides a full sleep stage classification while using the most complete diagnosis tool. It was implemented considering the known limitations for the use of algorithms in clinical practice. Its architecture thus reproduces the manual scoring process. A self-adaptative thresholding function was also implemented to provide a patient-dependent classification. The obtained results are comparable with the ones from sleep experts.The third algorithm, based on cardio-respiratory channels, provides a sleep stage classification while using a diagnostic tool that is insufficient for a manual sleep scoring, yet still highly used. The task is challenging but the obtained results are satisfying compared to literature.All three algorithms, which were designed for various diagnostic tools, will help sleep experts analyzing sleep
Gavelle, Sigrid. "TIPS-Diazoacétone : nouveau synthon pour l’élaboration de chaînes diazocarbonylées C-silylées – Application à la synthèse d’oxacycles silylés à 5 chaînons". Thesis, Le Mans, 2019. http://cyberdoc-int.univ-lemans.fr/Theses/2019/2019LEMA1034.pdf.
Α-diazocarbonyl compounds are important synthetic intermediates in organic chemistry. Decomposition of the diazo functionality promotes a wide range of synthetic transformations (X-H insertions, migrations or rearrangements). Few synthetic pathways are available to access these highly valuable α-diazocarbonyl scaffolds. In this context, our objective was to study the synthetic potential of the three-carbon building-block TIPS-diazoacetone to elaborate a range of original C-silyl diazocarbonylated compounds, through methyl-side aldol addition. More than a protective group for the diazo carbon, the TIPS moiety is a structural element allowing the access to original silylated molecules via diazo decomposition. The first part of this work was devoted to the development of a safe method to access diazoacetone, the direct precursor of TIPS-diazoacetone, without handling potentially explosive organic azides. A convenient one-pot, three-step procedure was implemented, involving in-situ formation of the intermediate organic azide. Transposition of the method to continuous flow process was also studied. The methyl-side aldolisation of TIPS-diazoacetone was then explored. Several parameters were investigated, providing conditions which allowed the synthesis of the expected original C-silylated aldols in good yields and in a reproducible way. Transformation of our C-silylated diazoaldols into original silylated compounds, through diazo decomposition, was initiated in the third part of the project. Intramolecular O-H insertion and Wolff rearrangement could be be achieved under acid catalysis to provide original C- or O-silylated five-membered O-heterocycles

REDD+ (Reducing Emissions from Deforestation and forest Degradation) schemes emerged in the early 2000s as an international mechanism to combat deforestation from a climate change mitigation perspective. Having joined REDD+ mechanisms since their creation, Congo Basin countries had to monitor deforestation and forest degradation. This thesis questions their capacity to carry out this activity. We used an empirical approach that first assessed the capacities of local populations to measure forest carbon stocks. Then we used the Research Integration and Utilization (RIU) model to analyze the governance and challenges of integrating expert and indigenous knowledge. Finally, we used the concept of storytelling to understand and explain how REDD+ has been advocated and disseminated for implementation in the Congo Basin. Our results show that local communities hold endogenous knowledge that allows them to contribute to the measurement of carbon stocks, and that the governance of knowledge transfer for monitoring is rather weak due to the inadequacy of the institutions in charge of forest management policies. Our analyses reveal the multiple socio-political and organizational barriers that inhibit the efforts of actors involved in monitoring deforestation in the three countries studied. Beyond monitoring, the analysis of speeches and interviews with actors involved in REDD+ projects implemented in the Congo Basin highlighted the storytelling of REDD+, which made it possible to broaden the reflection to explain the decline in the initial enthusiasm that REDD+ had generated

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.

This research contextualizes and analyzes the polemic and visionary artistic production of some cyberartists that have been constantly thinking over technological advances in the areas of genetics, robotics and telematics, and their relationship with the body and the conscience. These technologies are of central importance to the configuration of works that question the biological condition of the humankind and lay eyes on a possible symbiotic relation between man, machine and biotechnology, which might result in a new posthuman species. As outcome of the research the experimental part of this thesis the author narrates the development of a fictional universe inspired by those works and their creators\' considerations, and also presents several artistic works framed in paper and in hypermedia.

Historically and culturally norms are socially acceptable and can be problematic for people who behave in nonconformity with them because of risk of garner hatred. Mom-shaming is a term that describes the phenomenon when women get criticism and hatred for their act in their role of mother. A woman whom has been subject to this shaming, is mother and influencer Ida Warg. With the purpose of studying norms associated with female role as mother, this paper analyzes the visual design and composition of ten photographs posted by Ida Warg to her Instagram. Theories of gender and semiotics are used as frameworks, for qualitatively study if Ida Warg mediates her role as a mother normatively on her Instagram. The photographs are analyzed according to seven categories associated with mothering: Motherhood, Care and raise of child, Traditional nuclear family, Paid work, Leisure time, Entourage and Beauty. Considering the female role as mother, the result shows that historically rooted norms are still a fact. This paper argues for Ida Warg both certifying and challenging the social norms associated with mothering. Finally, this paper discusses how obsolete norm associated with the female role as mother, as a result of cyberhate such as mom-shaming, lingers and prevents gender equality. Henceforth, this paper also discusses the power of social media, being both reason why and solution to mom-shaming. One solution may be the exhortation of the hashtag #stopmomshaming.

For mothers to share their family life on social media has become a trend in the Swedish society. Isabella Löwengrip is one mother who does this. Isabella is a well known person in Sweden and has over 1,5 million followers on her blog. Isabella blogs about her everyday life and how it’s to live alone with two kids. A recurring pattern on the comments posted to Isabella’s blog are comments that criticize her way of taking care of her kids. This type of criticism is called ”momshaming”. This qualitative study analyzes how momshaming takes place on Isabella Löwengrip’s blog. The theoretical framework of the study is CDA and norms theory from a feminist perspective. The data analyzed are the comments posted to five selected posts from Isabella’s blog and we analyze them using the method CDA and seven analytical tools. The analytical tools helped us see what the readers reacted on and how momshaming are showed in comments. The study identifies four different themes in the momshaming comments; irony, time, ”they are just kids” and comparative with himself (the ones posting the comments). The study shows that momshaming takes place when the reader thinks that Isabella is going against the norm for a ”good” mother. Momshaming shows in the blog as negative comments about how Isabella raises her children. The most common theme is that Isabella doesn't spend much time with her kids and that she doesn’t treat them like they are kids.

A exclusão digital é uma questão que afeita a nossa sociedade dominada de tecnologia. Os pais da informática ubíqua sonhavam com uma proliferação total de tecnologia da informação. Mas a realidade em que vivemos ainda não está preparada para esse futuro. Há então uma necessidade de desenvolver programas para diminuir essa diferença entre os digitalmente incluídos e os excluídos. PROEJA-Transiarte é um projecto desenvolvido pela Universidade de Brasília, na cidade de Ceilândia, Distrito Federal do Brasil. Ele propõe uma abordagem diferente sobre a questão da exclusão digital, introduzindo a criação cooperativa de cyberarte, com base nas histórias de vida de cada participante, no currículo regular de EJA (Educação de Jovens e Adultos), a implementar assim o conceito da educação solidária. Este projecto de pesquisa investigou o papel desempenhado pela aprendizagem cooperativa, que os alunos colocam em prática durante as oficinas do projecto, na diminuição da exclusão digital da grande parte dos alunos. Foram examinadas as actividades dos alunos, analisando o desenvolvimento da cooperação deles, colocando-o no contexto da inclusão digital e social. Depois de uma pesquisa multidimensional sobre o tema, no contexto do PROEJA-Transiarte, a conclusão mostra o impacto que a aprendizagem cooperativa tem na redução da divisão digital, analisando a percepção dos alunos que actualmente participam, os pesquisadores activos no projecto, ou os ex-alunos que tenham melhorado as vidas deles depois de participar nas oficinas.
La fracture numérique est une question qui concerne beaucoup notre société dominée par la technologie. Les parents de l'informatique ubiquitaire rêvaient d'une prolifération totale de la technologie de l'information. Mais la réalité que nous vivons n'est pas encore prête pour cet avenir. Il y a un besoin actuel de développer des programmes afin de réduire cette différence entre les inclus et les exclus numérique. PROEJA-Transiarte est un projet organisé par Universidade de Brasília dans la ville de Ceilândia, District fédéral du Brésil. Il propose une approche différente sur la question de la fracture numérique, en introduisant la création coopérative de cyberart, basée sur les histoires de vie de chaque participant, dans le programme régulier d’EJA (Educação de Jovens e Adultos), mettant ainsi en oeuvre le concept de 'éducation solidaire. Ce projet de recherche a étudié le rôle joué par l'apprentissage coopératif des élèves, mis en pratique lors des ateliers du projet, dans la diminution de la fracture numérique une grande partie des élèves sentent. Il a examiné leurs activités, en analysant le développement de leur coopération, mettant en contexte de l'inclusion numérique et sociale. Après une recherche multidimensionnelle sur le thème, dans le cadre de PROEJA-Transiarte, la conclusion montre l'impact de l'apprentissage coopératif sur la réduction de la fracture numérique, en analysant la perception des élèves qui participent actuellement, des chercheurs actifs dans le projet, ou des anciens élèves qui ont eu leur vie améliorées par les ateliers auxquels ils ont participé à.
La brecha digital es un tema que concierne a nuestra sociedad dominada por la tecnología. Los padres de la computación ubicua soñaban con una proliferación total de tecnología de la información.

PROEJA-Transiarte es un proyecto organizado por la Universidad de Brasilia en la ciudad de Ceilândia, Distrito Federal de Brasil. Se propone un enfoque diferente en el tema de brecha digital, mediante la introducción de la creación cooperativa de cyberart, basada en las historias de vida de cada participante, en el currículo regular de la EJA (Educação de Jovens e Adultos), aplicando así el concepto de educación solidaria. Este proyecto de inquirió el papel del aprendizaje cooperativo, que los estudiantes ponen en práctica en los talleres del proyecto, en la disminución de la exclusión digital de una gran parte de los estudiantes. Examinó sus actividades, analizando el desarrollo de su cooperación, poniéndola en el contexto de la inclusión digital y social. Después de una investigación multidimensional sobre el tema, en el contexto de PROEJATransiarte, la conclusión muestra el impacto que el aprendizaje cooperativo tiene en la reducción de la brecha digital, analizando la percepción de los estudiantes que participan actualmente, los investigadores que trabajan en el proyecto, o los antiguos alumnos que tenían mejorando sus vidas debido a los talleres en que participaron.
