Syftet med denna studie är att undersöka hur den klimataktivistiska organisationen Extinction Rebellion Sverige gestaltar klimatfrågan och på vilka sätt denna gestaltning ligger till grund för skapandet av en kollektiv identitet. Det har jag gjort genom att fokusera på organisationens pressmeddelanden som de publicerat på sin hemsida. Det blir relevant att studera pressmeddelanden då dessa kan ses som en slags intern och extern kommunikationskanal där Extinction Rebellion Sverige kan förmedla sina värderingar och åsikter. Jag analyserar mitt material utifrån gestaltningsteorin och teorier om nya sociala rörelser och kollektiv identitet. De huvudsakliga resultaten visar på en väldigt alarmistisk syn på klimatfrågan där stort ansvar läggs på svenska politiker. Samtidigt finner de stor tilltro till deras aktioner av civil olydnad. Den kollektiva identitet som ges uttryck för i pressmeddelandena grundar sig mycket i att ifrågasätta systemet och att medlemmar skriver under på den verklighetsbild som presenteras. / The study aims to examine how the climate activism-organization Extinction Rebellion Sweden frames climate change and how the framing plays a part of their collective identity. This is done by studying press releases published on their website. I find press releases relevant for this study since it is a way of both internal and external communication where Extinction Rebellion Sweden can mediate their values and opinions. The theory being used is framing theory as well and theories of new social movements and collective identity. The results show that they tend to frame climate change in an alarmistic way where a lot of the responsibility is put on Swedish politicians. At the same time, they express great faith in civil disobedience as action. The collective identity being expressed in the press releases is based in questioning the system and the fact that their members agrees on the reality being presented.

The possible application of habit reversal to mentally ill institutional residents has not been investigated. While habit reversal holds considerable promise as a treatment mode, due to its rapid success and patient involvement in controlling his-her own behavior, further research is in order. To investigate the generality of habit reversal to an institutionalized population, the present study utilized self-monitoring, which has been found to be effective with hospitalized patients, and habit reversal, which has been found to be effective with a non-hospitalized population, as a treatment package for eliminating nervous tics. There are four major purposes for doing this present study: a) to see if modified habit reversal techniques could be used to successfully treat tics in institutionalised mental ill individuals, and in doing so look at; b) the effectiveness of procedures that involve the subject controlling his/her own behavior with that kind of population; c) To evaluate the within-in subject generality of the procedures by using a generalization measure in each subject’s living environment; and d) since Azrin and Nunn’s (1973) use of habit reversal was restricted to baseline-treatment (AB) replications, to provide an experimental analysis using a multiple baseline design.

abstract: Ultraviolet and optical light from stars is reddened and attenuated by interstellar dust, where different sightlines across a galaxy suffer varying amounts of extinction. Tamura et al. (2009) developed an approximate method to correct for dust extinction, dubbed the “βV method,” by comparing the observed to an empirical estimate of the intrinsic flux ratio of visible and ∼3.5 μm emission. Moving beyond that empirical approach, through extensive modeling, I calibrated the βV -method for various filters spanning the visible through near infrared wavelength range, for a wide variety of simple stellar populations (SSP) and composite stellar populations (CSP). Combining Starburst99 and BC03 models, I built spectral energy distributions of SSP and CSP for various realistic star formation histories, while taking metallicity evolution into account. I convolved various 0.44–1.65 μm filter throughput curves with each model spectral energy distribution (SED) to obtain intrinsic flux ratios, βλ,0. To validate the modeling, I analyzed spatially resolved maps for the observed V- and g-band to 3.6 μm flux ratios and the inferred dust-extinction values AV for a sample of 257 nearby galaxies. Flux ratio maps are constructed using point-spread function-matched mosaics of Sloan Digitial Sky Survey g- and r-band images and Spitzer/InfraRed Array Camera 3.6μm mosaics, with all of the pixels contaminated by foreground stars or background objects masked out. Dust-extinction maps for each galaxy were created by applying the βV -method. The typical 1σ scatter in βV around the average, both within a galaxy and in each morphological type bin, is ∼20%. Combined, these result in a ∼0.4 mag scatter in AV. βV becomes insensitive to small-scale variations in stellar populations once resolution elements subtend an area larger than 10 times that of a typical giant molecular cloud. I find noticeably redder V−3.6 μm colors in the center of star-forming galaxies and galaxies with a weak AGN. The derived intrinsic V −3.6 μm colors for each Hubble type are generally consistent with the modeling. Finally, I discuss the applicability of the βV dust-correction method to more distant galaxies, for which large samples of well-matched Hubble Space Telescope rest-frame visible and James Webb Space Telescope rest-frame ∼3.5μm images will become available in the near future. / Dissertation/Thesis / Doctoral Dissertation Astrophysics 2019

Previous research on social movements shows that as a consequence of social stratification, structurally privileged groups in society are more prone to engage in and take on leading positions in collective action than those who are structurally marginalised. This essay takes off in the puzzle of deficient inclusion in social movements that identify as inclusive, and looks at how that problem also appear empirically in the environmental movement Extinction Rebellion (XR). As attention to environmental issues and climate activism has increased significantly over the last years, many activists and scholars have pointed out the importance of tackling the problem with an intersectional feminist approach. Therefore, an interpretive discourse analysis with a “What’s the Problem Represented to be?” (WPR) approach is applied to the strategically chosen case of XR, and the results are interpreted through an intersectional feminist lens as conceptualised by Angela Davis (1981, 2016). The analysis contributes to the research problem through identifying two parallel problem representations, one representing the problem as proximate, local and technical-environmental and one representing it as current, global and societal-environmental. It is concluded that part of XR’s discourse rests on a problem representation that risks reproducing structural power relations. According to Davis’s conceptualisation of intersectional feminism this could have dire consequences for a movement which has shown to have potential to influence politics.

Two sections, Všeradice and Kosov, represent continuous sedimentary succession situated in the Prague Basin. No detailed research on stratigraphical level equal the N. kozlowskii graptolite zone focusing on chitinozoans, has not yet been conducted in the Prague Basin and is also very scarce globally. Limestone beds, examined for chitinozoans, were not very productive. Chitinozoan reaction on extinction is visible, if we compile data from both sections. The pre-extinct chitinozoan fauna is characterized by the Conochitinidae family. Samples from the post-extinct interval contained no chitinozoas. The interval of fauna recovery is characterized mainly by the Eisenackitina genera. In this interval, global zone for the uppermost Ludfordian, represented by E. barrandei, can be confirmed. In agreement with all the published literature, we have not found E. philipi, index taxa of the former global zone in the Prague Basin. E. lagenomorpha appears stratigraphically only slightly below E. barrandei and therefore it cannot substitute E. philipi, as it is used in Baltika region. chitinozoa, Prague Basin, Kozlowskii, Lau, extinction, Ludfordian, stratigraphy

Given the high salinity, prevailing annual high temperatures, and ultra-oligotrophic conditions in the Red Sea isolation and characterization of important microbial groups thriving in this environment is important in understanding the ecological significance and metabolic capabilities of these communities. By using a high-­throughput cultivation technique in natural seawater amended with minute amounts of nutrients, members of the rare biosphere (PS1), methylotrophic Betaproteobacteria (OM43), and the ubiquitous and abundant SAR11 group (Pelagibacterales), were isolated in pure culture. Phylogenetic analyses of Red Sea isolates along with comparative genomics with close representatives from disparate provinces revealed ecotypes and genomic differentiation among the groups. Firstly, the PS1 alphaproteobacterial clade was found to be present in very low abundance in several metagenomic datasets form divergent environments. While strain RS24 (Red Sea) harbored genomic islands involved in polymer degradation, IMCC14465 (East (Japan) Sea) contained unique genes for degradation of aromatic compounds. Secondly, methylotrophic OM43 bacteria from the Red Sea (F5, G12 and H7) showed higher similarities with KB13 isolate from Hawaii, forming a ‘H-­RS’ (Hawaii-­Red Sea) cluster separate from HTCC2181 (Oregon isolate). HTCC2181 members were shown to prevail in cold, productive coastal environments and had an nqrA-­F system for energy generation by sodium motive force. On the contrary, H-­RS cluster members may be better adapted to warm and oligotrophic environments, and seem to generate energy by using a proton-­translocating NADH:Quinone oxidoreductase (complex I; nuoA-­N subunits). Moreover, F5, G12, and H7 had unique proteins related to resistance to UV, temperature and salinity, in addition to a heavy metal ‘resistance island’ as adaptive traits to cope with the environmental conditions in the Red Sea. Finally, description of the Red Sea Pelagibacterales isolates from the Ia (RS39) and Ib (RS40) subgroups, principally revealed unique putative systems for iron uptake and myo-inositol utilization in RS39, and a potential phosphonates biosynthetic pathway present in RS40. The findings presented here reflect how environments influence the genomic repertoire of microbial communities and shows novel metabolisms and putative pathways as unique adaptive qualities in diverse microbes encompassing from rare to predominant bacterioplankton groups from the Red Sea.

>Magister Scientiae - MSc / In principle, an enrichment of resources in predator-prey systems show prompts destabilisation of a framework, accordingly, falling trophic communication, a phenomenon known to as the \Paradox of Enrichment" [54]. After it was rst genius postured by Rosenzweig [48], various resulting examines, including recently those of Mougi-Nishimura [43] as well as that of Bohannan-Lenski [8], were completed on this problem over numerous decades. Nonetheless, there has been a universal none acceptance of the \paradox" word within an ecological eld due to diverse interpretations [51]. In this dissertation, some theoretical exploratory works are being surveyed in line with giving a concise outline proposed responses to the paradox. Consequently, a quantity of di usion-driven models in mathematical ecology are evaluated and analysed. Accordingly, piloting the way for the spatial structured pattern (we denote it by SSP) formation in nonlinear systems of partial di erential equations [36, 40]. The central point of attention is on enrichment consequences which results toward a paradoxical state. For this purpose, evaluating a number of compartmental models in ecology similar to those of [48] will be of great assistance. Such displays have greater in uence in pattern formations due to diversity in meta-population. Studying the outcomes of initiating an enrichment into [9] of Braverman's model, with a nutrient density (denoted by n) and bacteria compactness (denoted by b) respectively, suits the purpose. The main objective behind being able to transform [9]'s system (2.16) into a new model as a result of enrichment. Accordingly, n has a logistic- type growth with linear di usion, while b poses a Holling Type II and nonlinear di usion r2 nb2 [9, 40]. Five fundamental questions are imposed in order to address and guide the study in accordance with the following sequence: (a) What will be the outcomes of introducing enrichment into [9]'s model? (b) How will such a process in (i) be done in order to change the system (2.16)'s stability state [50]? (c) Whether the paradox does exist in a particular situation or not [51]? Lastly, (d) If an absurdity in (d) does exist, is it reversible [8, 16, 54]? Based on the problem statement above, the investigation will include various matlab simulations. Therefore, being able to give analysis on a local asymptotic stability state when a small perturbation has been introduced [40]. It is for this reason that a bifurcation relevance comes into e ect [58]. There are principal de nitions that are undertaken as the research evolves around them. A study of quantitative response is presented in predator-prey systems in order to establish its stability properties. Due to tradeo s, there is a great likelihood that the growth rate, attack abilities and defense capacities of species have to be examined in line with reviewing parameters which favor stability conditions. Accordingly, an investigation must also re ect chances that leads to extinction or coexistence [7]. Nature is much more complex than scienti c models and laboratories [39]. Therefore, di erent mechanisms have to be integrated in order to establish stability even when a system has been under enrichment [51]. As a result, SSP system is modeled by way of reaction-di usion di erential equations simulated both spatially and temporally. The outcomes of such a system will be best suitable for real-world life situations which control similar behaviors in the future. Comparable models are used in the main compilation phase of dissertation and truly re ected in the literature. The SSP model can be regarded as between (2018-2011), with a stability control study which is of an original.

This thesis aims to explore the new concept of green populism and to explore if Extinction Rebellion can be seen as a new social movement. The concept of green populism is based on Cas Mudde’s ideational approach to populism and Dobson’s approach to green ideology. The theories will form a categorization of green populism to see if any of these elements are visible in Extinction Rebellion’s discourse. The combination of the two theories helps to define the elements or categories of green populism: Ecological Crisis of Cosmic Proportion, Victimizing “the People”, Identifying and/or blame the antagonist, Green Action, Scientific Evidencing, and Intergenerational Justice. The theories on new social movements is based on theories from scholars such as Alberto Melucci, Alain Touraine and Manuel Castells to help us understand what characterizes a new social movement. The four following characteristics of new social movements was highlighted: They focus on non-material issues, they tend to emphasize different protest tactics, they often have a horizontal organization, and they often use symbolic action. To answer the research questions in this thesis, a qualitative text analysis will be conducted. A qualitative text analysis focuses on certain selected aspects of the material which are determined by the aim and research questions. The qualitative text analysis is applied to the captions of eight selected Instagram-posts from Extinction Rebellion’s official account. The analysis leads to the conclusion that Extinction Rebellion can be seen as a new social movement, with a few exceptions regarding their focus on non-material issues. Another conclusion is that we were able to find elements of green populism in Extinction Rebellion’s discourse. The final conclusion is that green populism should be seen as a theoretical and analytical tool for analyzing communication rather than a label of environmental actors.

Research on transformations has recognized that trajectories towards sustainability are negotiated and contested through framings and narratives. There is, however, still a greater need to explore the role of social movements and their ability to characterize a problem, propose solutions and motivate the public to become engaged. This holds particularly true for the extensive field of climate politics in which different climate change framings compete. In recent years, a new wave of climate activism has emerged amidst an increased sense of urgency and severity of the climate crisis. One of the driving forces, Extinction Rebellion (XR), has managed to engage large numbers of people while making radical demands to the government. However, critical voices have challenged XR’s use of politically “neutral” language which communicates climate change in moral rather than political terms for displacing power and conflict. Drawing on framing theory and post-foundational political theory, I examine how XR UK frames the climate crisis in relation to political change, to better understand how the movement navigates between consensus and antagonism in the context of a depoliticization of climate change discourses. The analysis is based on a collection of semi-structured interviews with XR UK activists as well as key movement documents.  The analysis and subsequent discussion reveal a dynamic and contentious discursive field, with key findings including the identification of three collective action frames: (1) Climate Breakdown, (2) Web of Life and (3) Global Justice. These are linked together by the Global Climate Emergency master frame. The degree to which the frames are (de-)politicized varies and reflects different interpretations of transformation towards sustainability.
