The Articulation Between Soft Law and Hard Law in the Legal Management of Covid-19 in France and Sweden : Two asymmetrical strategies revealing a specific “administrative citizenship”
- 2024
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The legal strategies employed by France and Sweden to combat the Covid-19 pandemic differed significantly. Indeed, the articulation of hard law and soft law instruments varied, particularly due to differences in the trust placed by the state in its citizens. Meanwhile, both countries faced the same necessity of implementing efficient and effective standards designed to combat the pandemic. However, the fluctuating context in which these norms were established, along with the difficulty for the intended recipients to distinguish between what was mandatory and what was merely advisory, significantly contributed to the lack of legibility in health regulations in both countries.

- In the Mediterranean area, the 4.2 ka BP event is recorded with contrasting expressions between regions. In the southern Alps, the high-altitude Lake Petit (Mercantour Massif, France; 2200 m a.s.l.) offers pollen and diatom-rich sediments covering the last 4800 years. A multi-proxy analysis recently revealed a detrital pulse around 4200 cal BP due to increasing erosion in the lake catchment. The involvement of a rapid climate change leading to increasing runoff and soil erosion was proposed. Here, in order to clarify this hypothesis, we measured the oxygen isotope composition of diatom silica frustules (δ 18 O diatom ) from the same sedimentary core. Diatoms were analysed by laser fluorination isotope ratio mass spectrometry after an inert gas flow dehydration. We additionally enhanced the accuracy of the age-depth model using the Bacon R package. The δ 18 O diatom record allows us to identify a 500-year time lapse, from 4400 to 3900 cal BP, where δ 18 O diatom reached its highest values (> 31). δ 18 O diatom was about 3 ‰ higher than the modern values and the shifts at 4400 and 3900 cal BP were of similar amplitude as the seasonal δ 18 O diatom shifts occurring today. This period of high δ 18 O diatom values can be explained by the intensification of 18O-enriched Mediterranean precipitation events feeding the lake during the ice-free season. This agrees with other records from the southern Alps suggesting runoff intensification around 4200 cal BP. Possible changes in other climatic parameters may have played a concomitant role, including a decrease in the contribution of 18 Odepleted Atlantic winter precipitation to the lake water due to snow deficit. Data recording the 4.2 ka BP event in the northwestern Mediterranean area are still sparse. In the Lake Petit watershed, the 4.2 ka BP event translated into a change in precipitation regime from 4400 to 3900 cal BP. This record contributes to the recent efforts to characterize and investigate the geographical extent of the 4.2 ka BP event in the Mediterranean area.

Dior Salve a la Reina : Cristina Fernández's Fashionable Pleasures and her Constant War Against the Media
- 2013
-
Konferensbidrag (refereegranskat)abstract
- Is an austerity discourse compatible with ostentation? And if so, how can the contempt against the middle class be compatible with the veneration of a wealthy leader? Why is Cristina Fernandez’s indulgent luxury forgiven while the working middle class is stigmatized as privileged oligarchs? How does this relate to the controversial and iconic figure of Eva Duarte de Perón? The paper describes the dichotomy between Cristina Fernandez’s national populist discourse and her personal preference for high-end brands that had turned her into a fashion icon, capturing the attention of fashion bloggers, international newspapers, and even Vogue. Theoretically framed by O’Donell’s conceptualization of Delegative Democracies, the presentation will explore how disguised under a veneer of socialism—and pursuing Chavez’s model for Venezuela—Argentina’s president has mobilized a campaign to control the local Media leading to a confrontation with those journalists who persistently try to unmask her luxurious lifestyle, shopping preferences, and unclear finances. This contradiction between luxury and utterance is not new to the Argentine masses. The iconic figure of Evita was often under attack, accused of enjoying the same lifestyle as those she criticized. The parallelism between these two figures draws an interesting conclusion about the role of Media, performance, nostalgia, and fandom in Latin-American politics.*Play on words exchanging Dios (God in Spanish) for Dior as in “Dior (God) Save the Queen.”

Edith Head : From Costume Designer to Fashion Expert
- 2019
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Costume designer Edith Head has become a symbol of Hollywood costume designers. With more than 50 years of career designing for the big screen, her iconic look has inspired several characters that pay homage to her legacy. Edith Head started her career in 1924 as Howard Greer’s assistant. Without any background in drawing or costume design, Head rapidly ascended to head of the costume department in 1937, when Travis Banton left Paramount and join Howard Greer in his Beverly Hills fashion atelier. Scholars have presented her career as a linear story of costume design success, focusing mostly on her time at Paramount Pictures and basing arguments onHead’s own media declarations. However, Head’s media appearances and the widespread popularity as a public persona demonstrate that a large part of her work for the studio rested on being a promoter by exploiting her role as a mediator of fashion discourses for female audiences. Head used the looks of the stars to educate women into finding “their type” and showed them how to adapt screen looks for real-life situations. This paper looks at the role of Edith Head as a cultural translator of fashion, guiding American woman into the meaning of style and femininity in post-war America, by focusing on Head’s radio segments, books, and her work as the Academy Awards fashion consultant. The presentation will demonstrate that Head was a key PR figure for the studio and that this strategy also worked on her favor to perpetuate her position in the job market after the demise of the studio system.

"Because nobody likes Chinese girls” : Intersecting identities and emotional experiences of subordination and resistance in school life

- How do emotions enter into children’s negotiated understandings and situated uses of categories of identity? This question guided a revisit to an ethnographic study of a multi-cultural context in Oakland, California. A focus group discussion among four Chinese American girls just graduating from elementary school and an interviewer, also Chinese American, was chosen for closer study. This secondary analysis focuses on how the girls engaged in school events and how in the interview they shared experiences of being excluded and rejected by peers. Thus, both reports about life in school and lived life in the group discussion were analyzed in ways that followed the girls’ individual and collective emotional dynamics. Emotional tension between using and being used by categories drove their stories about belonging, exclusion and subordination, and resistance. The girls’ handling of social identities in relation to language use, required activities, and girly appearance in school demonstrated how they were able to draw on an eclectic and intersecting mix of categories. In the containing setting of the focus group, the girls processed their raw emotional experience of being taunted and humiliated. In the process they could challenge and destabilize the meanings attached to the categories of identity used against them. Therefore, intersectional analyses cannot take any specific meanings of social categories such as gender, ethnicity/race, and age, as the starting points. Rather, in each specific instance, the meanings of social categories will emerge as the results of the analysis.

Bias dependence of perpendicular spin torque and of free- and fixed-layer eigenmodes in MgO-based nanopillars
- 2011

Tidskriftsartikel (refereegranskat)abstract
- We have measured the bias voltage and field dependence of eigenmode frequencies in a magnetic tunnel junction with MgO barrier. We show that both free layer (FL) and reference layer (RL) modes are excited, and that a crossover between these modes is observed by varying external field and bias voltage. The bias voltage dependence of the FL and RL modes are shown to be dramatically different. The bias dependence of the FL modes is linear in bias voltage, whereas that of the RL mode is strongly quadratic. Using modeling and micromagnetic simulations, we show that the linear bias dependence of FL frequencies is primarily due to a linear dependence of the perpendicular spin torque on bias voltage, whereas the quadratic dependence of the RL on bias voltage is dominated by the reduction of exchange bias due to Joule heating, and is not attributable to a quadratic dependence of the perpendicular spin torque on bias voltage.

Decoherence and Mode Hopping in a Magnetic Tunnel Junction Based Spin Torque Oscillator

Tidskriftsartikel (refereegranskat)abstract
- We discuss the coherence of magnetic oscillations in a magnetic tunnel junction based spin torque oscillator as a function of the external field angle. Time-frequency analysis shows mode hopping between distinct oscillator modes, which arises from linear and nonlinear couplings in the Landau-Lifshitz-Gilbert equation, analogous to mode hopping observed in semiconductor ring lasers. These couplings and, therefore, mode hopping are minimized near the current threshold for the antiparallel alignment of free-layer with reference layer magnetization. Away from the antiparallel alignment, mode hopping limits oscillator coherence.

The seasonal cycle of ice-nucleating particles linked to the abundance of biogenic aerosol in boreal forests

- Ice-nucleating particles (INPs) trigger the formation of cloud ice crystals in the atmosphere. Therefore, they strongly influence cloud microphysical and optical properties and precipitation and the life cycle of clouds. Improving weather forecasting and climate projection requires an appropriate formulation of atmospheric INP concentrations. This remains challenging as the global INP distribution and variability depend on a variety of aerosol types and sources, and neither their short-term variability nor their long-term seasonal cycles are well covered by continuous measurements. Here, we provide the first year-long set of observations with a pronounced INP seasonal cycle in a boreal forest environment. Besides the observed seasonal cycle in INP concentrations with a minimum in wintertime and maxima in early and late summer, we also provide indications for a seasonal variation in the prevalent INP type. We show that the seasonal dependency of INP concentrations and prevalent INP types is most likely driven by the abundance of biogenic aerosol. As current parameterizations do not reproduce this variability, we suggest a new mechanistic description for boreal forest environments which considers the seasonal variation in INP concentrations. For this, we use the ambient air temperature measured close to the ground at 4.2 m height as a proxy for the season, which appears to affect the source strength of biogenic emissions and, thus, the INP abundance over the boreal forest. Furthermore, we provide new INP parameterizations based on the Ice Nucleation Active Surface Site (INAS) approach, which specifically describes the ice nucleation activity of boreal aerosols particles prevalent in different seasons. Our results characterize the boreal forest as an important but variable INP source and provide new perspectives to describe these new findings in atmospheric models.

Obligatory homeothermy of mesic habitat-adapted African striped mice, Rhabdomys pumilio, is governed by seasonal basal metabolism and year-round 'thermogenic readiness' of brown adipose tissue

- Small mammals undergo thermoregulatory adjustments in response to changing environmental conditions. Whereas small heterothermic mammals can employ torpor to save energy in the cold, homeothermic species must increase heat production to defend normothermia through the recruitment of brown adipose tissue (BAT). Here, we studied thermoregulatory adaptation in an obligate homeotherm, the African striped mouse (Rhabdomys pumilio), captured from a subpopulation living in a mesic, temperate climate with marked seasonal differences. Basal metabolic rate (BMR), nonshivering thermogenesis (NST) and summit metabolic rate (M-sum) increased from summer to winter, with NST and M-sum already reaching maximal rates in autumn, suggesting seasonal preparation for the cold. Typical of rodents, cold-induced metabolic rates were positively correlated with BAT mass. Analysis of cytochrome c oxidase (COX) activity and UCP1 content, however, demonstrated that thermogenic capacity declined with BAT mass. This resulted in seasonal differences in NST being driven by changes in BMR. The increase in BMR was supported by a comprehensive anatomical analysis of metabolically active organs, revealing increased mass proportions in the cold season. The thermoregulatory response of R. pumilio was associated with the maintenance of body mass throughout the year (48.3 +/- 1.4 g), contrasting large summer-winter mass reductions often observed in Holarctic rodents. Collectively. bioenergetic adaptation of this Afrotropical rodent involves seasonal organ adjustments influencing BMR, combined with a constant thermogenic capacity dictated by trade-offs in the thermogenic properties of BAT. Arguably, this high degree of plasticity was a response to unpredictable cold spells throughout the year. Consequently, the reliance on such a resource-intensive thermoregulatory strategy may expose more energetic vulnerability in changing environments of food scarcity and extreme weather conditions due to climate change, with major ramifications for survival of the species.
