O dever de informar do fornecedor e a eficácia jurídica da informação nas relações de consumo: precisões conceituais

Kretzmann, Renata Pozzi January 2018 (has links)
O dever de informar é multifacetado: é ao mesmo tempo direito e dever e permeia todo o sistema protetivo do Código de Defesa do Consumidor, irradiando seus efeitos desde a fase pré-contratual da relação de consumo. Trata-se de dever que encontra fundamento na boa-fé, baseando-se na necessidade de tutela das legítimas expectativas do consumidor. O presente estudo objetiva a análise das características e correlações do dever de informar do fornecedor nas relações de consumo e as consequências de sua violação, como a não obrigatoriedade do conteúdo contratual desconhecido, o cumprimento forçado da oferta e a responsabilidade por vício e defeito de informação. / The duty to inform is multifaceted: it is at the same time right and duty and pervades the entire protective system of the Consumer Protection Code, radiating its effects since the pre-negotiation phase of the consumption relation. It arises from the good faith principle, the contractual trust and it is based on the need to safeguard the legitimate expectations of the consumer. The present study aims to address the characteristics and correlations of the supplier's duty to inform in consumer relations and the consequences of its violation, such as the non-compulsory contractual unknown content, the forced fulfillment of the offer and the liability for damages caused by lack or defect of information.

Politisk aktivism i skolan? : En diskursanalys av Greta Thunbergs skolstrejk för klimatet / Political Activism in School? : A Discourse Analysis of School Strike for Climate by Greta Thunberg

Aronsson, Tilda January 2019 (has links)
A few weeks before the Swedish election in September 2018, a young girl named Greta Thunberg decidedto leave school every Friday and instead sit outside the Swedish parliament in Stockholm to raise awarenessabout the climate. This “school strike for climate” has since then developed to be a world-wide phenomenonand on the 15th of March more than 1.4 million youngsters participated in more than 100 countries.However, these actions have been subject of lots of debate in media; Greta being both cherished andcriticized. Framed within the questions about what motivates the political participation and in what way theschool takes a stand, this thesis aims to analyze “school strike for climate” in relation to the role of bothknowledge and fostering in the Swedish school. Through theories of street-level bureaucracy and politicalparticipation, accompanied by Carol Bacchis discourse perspective what´s the problem represented to be the studyexamines 32 Swedish newspaper articles. The result is a variety of problem representations, getting legitimized through law or moral, but also through a representation which hold both school and the pupils responsible for result in school. One of thedevelopments in the discourse is that during time and enlarging of the political activism, the youngster’sactions more and more is characterized as political participation than of an individual choice. This alsomeans that schools have to take a stand up on an organizational level, where many principals refer to schoolattendance and the law. When political activism is legislated through the curriculum it seems to be adidactical choice by the teachers, whom within their free space as professional street-level bureaucrats mayhave varying opportunities to use the theme within their teaching. Over all, the discourse focus more uponthe climate than democratic ideals, which suggests an unused potential of “school strike for climate” incivic´s education.

Påverkar en potentiell väns beteende mäns och kvinnors vilja att vara vän? : En studie om hur vuxnas vilja att vara vän med en individ påverkas beroende på om individen är impulsiv eller inte / Does a potential friend’s behavior affect men’s and women’s will to be friends? : A study on how adults’ willingness to be friends with an individual is affected depending on whether the individual is impulsive or not

Karlsson, Emelie January 2020 (has links)
Syftet med denna studie var att undersöka om upplevd impulsivitet hos en potentiell vän kan påverka män respektive kvinnors vilja att vara vän med den personen.   Studien genomfördes med en 2x2 oberoende mätning med mellangruppsdesign. Den beroende variabeln var skattning av viljan till vänskap. Första oberoende variabeln var personlighetstyp som presenterades i två olika scenarier med två betingelser; impulsiv och eftertänksam. Den andra oberoende variabeln var kön med två betingelser; man och kvinna. Båda scenarier var identiska förutom omformuleringar beroende på betingelse. Självskattad vänskapskvalité och självskattat personlighetsdrag kontrollerades för. Tidigare forskning baserad på barn har visat att impulsiva barn blivit mer avvisade och mer impopulära än andra barn. Genom att undersöka hur vuxnas vilja att vara vän med en person påverkas beroende på hur personen beter sig är därför aktuellt eftersom det då kan framkomma om detta förekommer även i vuxen ålder. En 2x2 oberoende ANOVA visade att det fanns en interaktionseffekt mellan Kön x Scenario vilket indikerar att kön och scenario spelade stor roll för den beroende variabeln. Studien visade att kön hade en påverkan på resultatet; kvinnor var mindre benägna till att vara vän med en impulsiv person jämfört med en eftertänksam person. För männen i undersökningen spelade inte scenario någon roll gällande viljan att vara vän vilket indikerar på att de bryr sig mindre om en potentiell vän är impulsiv eller eftertänksam. Möjligen kan det vara att kvinnor lägger mer energi på sina vänskapskretsar och hur en potentiell vän ska bete sig i större utsträckning än vad män gör. / The aim with this study was to investigate whether perceived impulsivity of a potential friend can affect men’s and women’s willingness to be friends with that person. The study was conducted with a 2x2 independent measurement with a between groups design. The dependent variable was a self-assessed rating of the will of friendship. The first independent variable was the personality type that was presented in the two different scenarios with two conditions; impulsive and thoughtful. The second independent variable was gender which also had two conditions; men and women. The scenarios was identical except for some language changes depending on the condition. Self-assessed rating of friendship quality and self-assessed rating of personality traits were controlled for. Previous research based on children has shown that impulsive children become more peer rejected and unpopular than other children. By examining how adults’ willingness to be friends with a person is affected, depending on the other person’s behavior, it may be concluded that this rejection even occurs in adulthood. A 2 x 2 independent ANOVA indicated that there was an interaction effect between Gender x Scenario which means that gender and scenario had a great influence on the dependent variable. The study indicated that gender had an impact on the result; women were less likely to be friends with an impulsive person compared to a person that is thoughtful. The two different scenarios did not matter for the men in this study regarding the will to be friends, which indicates that they did not care about if a potential friend was impulsive or thoughtful. This could possibly depend on that women put greater effort in their relationships with their friends and more thought in how a potential friend should behave to a greater extent than men do.

How a TikTok video by Finnish police is representing the victim : A Multimodal critical discourse analysis on victim blaming in Tiktok video

Karppinen, Ruut January 2021 (has links)
The Finnish police have power and influence as they are gate keepers of the criminal justice system. Governmental crime reduction policies rely on the actions of the police and in 2020 the Finnish police made a TikTok video to warn adolescences about dangers of sexting. My thesis uses Lerner’s Just world hypothesis and Bacchi’s What’s the problem represented to be as a theoretical framework, and multimodal critical discourse analysis (MCDA) to identify how the victim is represented in the TikTok video. The analysis on the content of the TikTok video is representing the victim as culpable for the crime against him/her. When the analysis is applied to the theoretical framework, it can be argued that the instructive TikTok video bears pressing social and institutional problems and extends people’s responsibility for avoiding crime and therefore fails achieving a balanced policy between crime prevention and criminal justice response.

Právo být zapomenut v kontextu moderního pojetí ochrany osobních údajů v EU a USA / The right to be forgotten in the context of a modern concept of personal data protection in the EU and the USA

Denemark, Jaroslav January 2019 (has links)
Thesis title The right to be forgotten in the context of a modern concept of personal data protection in the EU and the USA Abstract The main topic of the thesis is the analysis of the right to be forgotten and its place in today's digital world and information society. In particular, the author discusses a different approach to the protection of personal data in Europe and in the United States of America within the context of the conflict between right to privacy and freedom of expression and right to free access to information. The author describes different conceptions of significance of these rights and different value ladder in connection in their mutual assessment. Based on outlining the different approaches to aforementioned rights, the author examines the inclusion of the right to be forgotten within the two legal cultures and consequently examines different forms of the right to be forgotten. Such forms are introduced in the context of privacy rights in the European union and presented in the was, how the legislation has been developing as the privacy laws evolved. Author closely examines the case-law of the Court of Justice of the European Union which is focused on right to be forgotten. Attention is also paid to the practical implementation of the right to be forgotten in accordance with the...

Corticotropin Releasing Factor up-Regulates the Expression and Function of Norepinephrine Transporter in SK-N-Be (2) m17 Cells

Huang, Jingjing, Tufan, Turan, Deng, Maoxian, Wright, Gary, Zhu, Meng Yang 01 October 2015 (has links)
Corticotropin releasing factor (CRF) has been implicated to act as a neurotransmitter or modulator in central nervous activation during stress. In this study, we examined the regulatory effect of CRF on the expression and function of the norepinephrine transporter (NET) in vitro. SK-N-BE (2) M17 cells were exposed to different concentrations of CRF for different periods. Results showed that exposure of cells to CRF significantly increased mRNA and protein levels of NET in a concentration- and time-dependent manner. The CRF-induced increase in NET expression was mimicked by agonists of either CRF receptor 1 or 2. Furthermore, similar CRF treatments induced a parallel increase in the uptake of [3H] norepinephrine. Both increased expression and function of NET caused by CRF were abolished by simultaneous administration of CRF receptor antagonists, indicating a mediation by CRF receptors. However, there was no additive effect for the combination of both receptor antagonists. Chromatin immunoprecipitation assays confirm an increased acetylation of histone H3 on the NET promoter following treatment with CRF. Taken together, this study demonstrates that CRF up-regulates the expression and function of NET in vitro. This regulation is mediated through CRF receptors and an epigenetic mechanism related to histone acetylation may be involved. This CRF-induced regulation on NET expression and function may play a role in development of stress-related depression and anxiety. This study demonstrated that corticotropin release factor (CRF) up-regulated the expression and function of norepinephrine transporter (NET) in a concentration- and time-dependent manner, through activation of CRF receptors and possible histone acetylation in NET promoter. The results indicate that their interaction may play an important role in stress-related physiological and pathological status.

Corticosterone up-Regulates Expression and Function of Norepinephrine Transporter in SK-N-BE(2)C Cells

Sun, Zhongwen, Fan, Yan, Zha, Qinqin, Zhu, Meng Y. 01 April 2010 (has links)
Glucocorticoids affect cellular and molecular events in brains by modulating the expression of many genes during stress. In the present study, we examined the regulatory effect of corticosterone on the expression and function of the norepinephrine transporter (NET) in vitro. The results show that exposure of SK-N-BE(2)C cells to corticosterone for 14 days significantly increased mRNA (up to 43%) and protein (up to 71%) levels of NET in the concentration- dependent manner. Longer exposure (21 days) resulted in greater increases in the levels of mRNAs (up to about 160%) and proteins (up to about 250%) of the NET. The up-regulatory effect of corticosterone on NET expression lasted a persistent period after cessation of exposure. Associated with the corticosterone-induced enhancement in NET expression, there was a parallel increase in the uptake of [3H]norepinephrine by SK-N-BE(2)C cells. Increased NET expression and function were abolished after exposure of cells to corticosterone in combination with mifepristone or spironolactone, two specific antagonists of corticosteroid receptors. This is consistent with the hypothesis that corticosterone-induced NET up-regulation is mediated by corticosteroid receptors. Nevertheless, there was no synergistic effect for a combination of both corticosteroid receptor antagonists. A similar up-regulation of NET protein levels was also observed after exposing PC12 cells to corticosterone. The present findings demonstrate that corticosterone up-regulates the expression and function of NET in vitro, indicating the action of corticosterone on the noradrenergic phenotype may play an important role in the correlation between stress and the development of depression.

Effects of Transcription Factors phox2 on Expression of Norepinephrine Transporter and Dopamine β-Hydroxylase in SK-N-Be(2)C Cells

Fan, Yan, Huang, Jingjing, Kieran, Niamh, Zhu, Meng Yang 01 September 2009 (has links)
Phox2a and Phox2b are two homeodomain proteins that control the differentiation of noradrenergic neurons during embryogenesis. In the present study, we examined the possible effect of Phox2a/2b on the in vitro expression of the norepinephrine transporter (NET) and dopamine β-hydroxylase (DBH), two important markers of the noradrenergic system. SK-N-BE(2)C cells were transfected with cDNAs or short hairpin RNAs specific to the human Phox2a and Phox2b genes. Transfection of 0.1 to 5 μg of cDNAs of Phox2a or Phox2b significantly increased mRNA and protein levels of NET and DBH in a concentration-dependent manner. As a consequence of the enhanced expression of NET after transfection, there was a parallel increase in the uptake of [ 3H]norepinephrine. Co-transfection of Phox2a and Phox2b did not further increase the expression of noradrenergic markers when compared with transfection of either Phox2a or Phox2b alone. Transfection of shRNAs specific to Phox2a or Phox2b genes significantly reduced mRNA and protein levels of NET and DBH after shutdown of endogenous Phox2, which was accompanied by a decreased [3H]norepinephrine uptake. Furthermore, there was an additive effect after cotransfection with both shRNAs specific to Phox2a or Phox2b genes on NET mRNA levels. Finally, the reduced DBH expression caused by the shRNA specific to Phox2a could be reversed by transfection with Phox2b cDNA and vice versa. The present findings verify the determinant role of Phox2a and Phox2b on the expression and function of NET and DBH in vitro. Further clarifying the regulatory role of these two transcription factors on key proteins of the noradrenergic system may open a new avenue for therapeutics of aging-caused dysfunction of the noradrenergic system.

Children’s Rights in International Social Work : A critical analysis of a campaign by UNICEF

Carlsson, Josefine January 2020 (has links)
Children’s rights and childhood are concepts that are a part of everyday discussions for many people around the world, but the understanding of the concepts shifts through time and space. The Convention on the Right of the Child, CRC, is supposed to protect children’s rights and relies upon the idea of childhood that describes children both as active agents and in need of protection. UNICEF, an organization within the UN, has the CRC as a guiding principle to achieve its mission to improve the lives of every child globally. However, previous research has criticized the CRC and UNICEF for ignoring particular children’s needs and having a western bias. Thus, even if an international social work program aims to protect children’s rights, it can end up excluding the needs of particular groups of children. This study aims to provide an understanding of how the problem of children’s rights discriminations is represented to be in UNICEF’s campaign #ENDviolence. The study fulfills the aim by using Carol Bacchi’s approach “What’s the problem represented to be?” WPR, and its six guiding questions. The empirical data is UNICEF’s campaign report, because the present study aims to investigate children’s rights discrimination, and the organization works with children and uses the CRC as a guiding principle. The study uses the WPR approach because it stresses that problems are created and given meanings through policies and programs. This study also uses the social constructionist theory and the two concepts, intersectionality and intertextuality, to provide a broader understanding. The results show that the campaign does only have a limited intersectional perspective, by not including children’s different identities, relating to such as race, nationality, alternative gender identification and sexuality, and abilities/disabilities, and it also does not acknowledge children’s multiple identities. Instead, the problem representation solely relies upon the concepts of sex (boy/girl) or age. Hence, the campaign leaves particular children and their needs unrecognized. An explanation for this approach is the campaign’s stable intertextual connection to the UN, and the writings, CRC and SDGs, Sustainable development goals. The campaign also tends to have a western bias, through silencing western countries, the data it uses and how it presents the data. The campaign ignores particular children and how institutional structures may affect them differently because of their identities. Thus, discrimination and violence against specific children can continue and suggested solutions would not necessarily help them.
