description: Uma das áreas mais determinantes da investigação em Ciências da Educação reporta-se a processos internos da Escola no âmbito da supervisão pedagógica. Constituindo a observação de aulas uma das dinâmicas centrais desses processos, o estudo da sua influência no desenvolvimento profissional dos professores reveste-se de grande pertinência. Conhecer as perceções dos professores sobre a observação de aulas, assim como identificar os fatores que inibem e os que facilitam a adesão a estas práticas, é determinante na implementação de modelos que tornem estes processos mais efetivos e que visem a mudança. Assim, o presente estudo pretende compreender em que medida a observação de aulas contribui para o desenvolvimento profissional dos professores. Para o efeito, optou-se, metodologicamente, por realizar uma pesquisa de cariz quantitativo, a partir da aplicação de um inquérito por questionário a nível nacional, em contexto de pandemia de Covid-19. No que respeita aos principais resultados obtidos, é possível concluir que a observação de aulas, embora não evidencie desencadear melhorias significativas no processo de ensino e aprendizagem, aparenta, contudo, possibilitar o enriquecimento do trabalho colaborativo e de práticas reflexivas, contribuindo para o desenvolvimento profissional dos professores e para a identificação de necessidades de formação. Com base nas conclusões, foi delineado um plano de ação para operacionalizar, de forma sistemática, as práticas de observação de aulas na Escola, de modo a permitir aos professores lidar com êxito, com as imperfeições inerentes a estas práticas, pois como processos humanos que são, não é de esperar que sejam perfeitos.

description: Este trabalho tem como objetivo geral identificar práticas de Marketing Educacional nas escolas públicas, tendo-se feito uma revisão sumária da literatura sobre a evolução do marketing (geral) até à emergência do Marketing Societal, do Marketing Educacional e a abordagem do Marketing 3.0 e 4.0. Exploraram-se, também, os normativos legais, a autonomia das escolas, a accountability e evidências dessas práticas associadas ao Marketing Educacional. Para o efeito, optou-se, metodologicamente, por implementar uma pesquisa predominantemente de cariz quantitativa através de um inquérito por questionário, realizado junto do(a)s diretores(as) dos agrupamentos de escolas e escolas não agrupadas de Portugal Continental. No que respeita aos principais resultados obtidos, é possível concluir que, apesar de haver evidências de predominar a orientação da gestão para a “produção” do serviço educativo, há práticas de Marketing Educacional nas escolas públicas. Contudo, as escolas parecem ter ainda uma consciência míope do que é o Marketing Educacional, pois há défice na identificação e na implementação dessas práticas, mesmo verificando-se que há escolas que fazem estudos de suporte às decisões da oferta formativa, de avaliação institucional e de satisfação junto dos alunos e restante comunidade educativa. Verifica-se, também, que há escolas que definem e implementam estratégias não só para cumprir os normativos legais, mas também para adequar os serviços aos alunos, tornando-os parte ativa da coprodução do serviço educativo.

description: In the paper we propose a direct method for recovering the Sturm-Liouville potential from the Weyl-Titchmarsh $m$-function given on a countable set of points. We show that using the Fourier-Legendre series expansion of the transmutation operator integral kernel the problem reduces to an infinite linear system of equations, which is uniquely solvable if so is the original problem. The solution of this linear system allows one to reconstruct the characteristic determinant and hence to obtain the eigenvalues as its zeros and to compute the corresponding norming constants. As a result, the original inverse problem is transformed to an inverse problem with a given spectral density function, for which the direct method of solution from arXiv:2010.15275 is applied. The proposed method leads to an efficient numerical algorithm for solving a variety of inverse problems. In particular, the problems in which two spectra or some parts of three or more spectra are given, the problems in which the eigenvalues depend on a variable boundary parameter (including spectral parameter dependent boundary conditions), problems with a partially known potential and partial inverse problems on quantum graphs.

Fiction's in the Know: Reassessing Epistemologies of Cognitive Science and (Un)Consciousness
Creators: name: Pirlet, Caroline
Publisher: name: KULT_online
Year: 2013

description: In Fictions of Cognition, Stephan Freißmann focuses on the circulation of ideas between scientific and literary writing. To sketch out what he argues to be a dialogic relationship between what he calls 'fictions of cognition' and cognitive science, the study focuses on the types of knowledge of cognition that can be formed on the basis of fiction, and the representation of (un)consciousness and cognitive science in fiction. After asserting the epistemic power of fiction and significantly expanding the spectrum of elements of narrative able to represent consciousness, six contemporary English and American novels, 'fictions of cognition', are analyzed in pairs according to dominant theme and their stance toward consciousness and/or cognitive science. The book convincingly relativizes the authority of science by emphasizing the cultural dynamics inherent in the negotiation process of knowledge formation. It is well-argued, intelligible, and an overall thought-provoking, relevant contribution to cognitive literary and cultural studies.

Lesbian social workers' experiences in their professional working relationships
Creators: name: McMackon, Bonnie
Publisher: name: University of British Columbia
Year: 2009

description: Lesbian social workers have been acutely aware of the inadequacies of the social work response to lesbian client needs. At a time when we are experiencing unprecedented gains in civil rights, we are also experiencing increased violence and renewed social and political oppression. Feminist research must start from the experiences of the researcher. As a lesbian feminist researcher, the concern of lesbian social workers' experiences in the workplace was sought. The present qualitative study examines the experiences of five lesbian social workers, all over forty-five years of age, primarily in middle management positions in the health field. Within a focus group, the participants discussed a variety of personal experiences within self-defined 'gay-positive' work environments. Content analysis was used to extrapolate themes. Visible lesbian and gay co-workers and especially supervisors created a 'gay-positive' work environment, however participants felt being an 'out' lesbian was compromised by a number of factors. These included internalized homophobia, institutional discrimination, feminist principles denied within a hierarchy, as well as self-censorship due to reactions from other employees. Homophobic expression increased when heterosexual representation decreased. Possibly due to their managerial status, and/or internalized homophobia, some ambivalence about being 'out' in their work environment also became evident. The findings are discussed in terms of implications for policy and practice in order to address homophobia and provide nondiscriminatory ethical practice in the profession of social work.

Rapid variability in TeV blazars: the case of PKS 2155-304
Creators: name: Ghisellini, G.
name: Tavecchio, F.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent Cherenkov observations of BL Lac objects showed that the TeV flux of PKS 2155-304 changed by a factor 2 in just 3-5 minutes. This fast variability can be accounted for if the emitting region is moving with a bulk Lorentz factor Gamma~50 and a similar relativistic Doppler factor. If this Gamma is adopted, several models can fit the data, but, irrespective of the chosen model, the jet is matter dominated. The Doppler factor requires viewing angles of the order of 1 degree or less: if the entire jet is as narrow as this, then we have problems with current unification schemes. This suggests that there are small active regions, inside a larger jet, moving faster than the rest of the plasma, occasionally pointing at us. Coordinated X-ray/TeV variability can discriminate between the different scenarios.

Simulation of phosphorylation-induced structural changes for DNA polymerase β, using molecular modelling
Creators: name: Idriss, Haitham
Publisher: name: F1000Research
Year: 2015

description: DNA polymerase beta is a 39 kDa enzyme that comprises two major domains, a 31 kDa domain responsible for the polymerase activity and an 8 kDa domain, which bind ssDNA and has a dRP Lyase activity. DNA polymerase beta was shown to be phosphorylated in vitro with Protein Kinase C at serines 44 and 55, resulting in loss of its polymerase enzymic activity, but not its ability to bind ss DNA. The enzyme has a potential phosphorylation site at tyrosine 250, reported on www.phosphosite.org. We set out to simulate potential phosphorylation-induced structural changes for DNA polymerase beta using molecular modelling algorithm (CHARMM22 and AMBER for serines and tyrosine, respectively) and published structural coordinates for the enzyme (pdb: 2FMS). Simulations with CHARMM22 were for 10 ns and with AMBER for 100 ns. RMSF plot of Ser44P showed highest deviation. RMSF plot of Ser55P and Ser44/55P showed a similar fluctuation pattern except at aa 1-75, the major part for ssDNA binding and dRP lyase domains. Radius for gyration (Rg) for apo_enzyme and Ser55P were consistent throughout the simulation. The Rg of Ser44P and Ser44/55P fluctuated throughout the simulation. Phosphorylation at Ser44, Ser55 and Ser44/55 induced major conformational fluctuations from apo_enzyme at the ssDNA binding domain and dNTP selection domain. Tyr250P enzyme was noticeably more dynamic than reference. The results may explain the Protein Kinase C phosphorylation-induced loss of enzymic activity reported in vitro. Data also suggest that phosphorylation at tyrosine 250 is worthy of being investigated. Such studies may pave the way for simulating variations in the atomic structure for the other post-translationally modified (e.g. acetylated) form(s) for this and other enzymes/proteins and be used as an indicator that a potential modification may have structural (and functional) consequences.

Partimos de um questionário realizado via Google Formulário, com questões que se voltou a dar voz a estesprofissionais de maneira a conhecer as principais dificuldades enfrentadas por eles neste período. Os dados obtidos desvelam que embora os professores estejam tentando estabelecer uma relação de proximidade com as famílias e os estudantes, por meio do uso das tecnologias, estes têm enfrentado alguns percalços em se tratando do formato de ensino não presencial. Eles apontam a dificuldade de alcançar os estudantes, devido, principalmente, aos problemas de acesso às ferramentas digitais. Ademais, relatam que não apresentam formação adequada para algumas demandas deste cenário de Pandemia. Frente a isso, ressalta-se que faz-se necessário uma política de formação continuada pautada nas reais necessidades dos docentes, porquanto é emergencial a busca de saídas para que este novo modelo de ensino funcione de maneira qualitativa.

Emerging Concepts in Narratological Research: Authenticity and Narrative World-Disruption
Creators: name: Berning, Nora
Publisher: name: KULT_online
Year: 2013

description: The essay collections edited by Antonius Weixler (Authentisches Erzählen, 2012) and Markku Lehtimäki et al. (Narrative, Interrupted, 2012) constitute an attempt to establish authenticity and interruption (in the sense of narrative world-disruption) as key concepts of postclassical narratological research. Authentisches Erzählen consists of a multifaceted account of authenticity, accounting both for genealogical transformations and discipline-specific permutations of the term. For its part, Narrative, Interrupted focuses on potentially disruptive elements of narrative communication, and the contributors seek to analyse such phenomena as anti-causality and narrative world-disruption that structuralist narratology eschewed, while also challenging basic assumptions of contemporary narrative theory. Since interruption is one of the main catalysts of the effect of authenticity, the two volumes productively complement each other and make for an interesting contrapuntal read.

Active Galactic Nucleus Feedback in an Elliptical Galaxy with the Most Updated AGN Physics: Parameter Explorations

description: In a previous work, we have proposed a sub-grid model of active galactic nucleus (AGN) feedback by taking into account the state-of-the-art AGN physics, and used that model to study the effect of AGN feedback on the evolution of an isolated elliptical galaxy by performing two dimensional high-resolution (i.e., the Bondi radius is well resolved) simulations. In that work, typical values of model parameters were adopted. In the present work, we extend that study by exploring the effects of uncertainties of parameter values. Such a study is also useful for us to understand the respective roles of various components of the model. These parameters include the mass flux and velocity of AGN wind and radiative efficiency in both the hot and cold feedback modes, and the initial black hole (BH) mass. We find that the velocity of AGN wind in the hot mode is the most important quantity to control the typical accretion rate and luminosity of AGN, and the mass growth of the BH. The effect of the wind on star formation is less sensitive. Within the limited parameter range explored in the current work, a stronger AGN wind suppresses star formation within ~100 pc but enhances star formation beyond this radius, while the star formation integrated over the evolution time and the whole galaxy roughly remain unchanged. AGN radiation suppresses the BH accretion in a mild way, but dust is not considered here. Finally, a smaller initial BH mass results in a more violent evolution of the BH accretion rate. The corresponding AGN spends more time in the high-luminosity state and the percentage of BH mass growth is higher. Our results indicate the robustness of AGN feedback in keeping the galaxy quenched.

description: In the framework of the model assuming the formation of NUC on the pairs of Cu ions in CuO$_{2}$ plane the mechanism of hole carrier generation is considered and the interpretation of pseudogap and 60 K-phases in $YBa_{2}Cu_{3}O_{6+δ}$. is offered. The calculated dependences of hole concentration in $YBa_{2}Cu_{3}O_{6+δ}$ on doping $δ$ and temperature are found to be in a perfect quantitative agreement with experimental data. As follows from the model the pseudogap has superconducting nature and arises at temperature $T^{*}>T_{c\infty}>T_{c}$ in small clusters uniting a number of NUC's due to large fluctuations of NUC occupation. Here $T_{c\infty}$ and $T_{c}$ are the superconducting transition temperatures of infinite and finite clusters of NUC's, correspondingly. The calculated $T^{*}(δ)$ and $T_{n}(δ)$ dependences are in accordance with experiment. The area between $T^{*}(δ)$ and $T_{n}(δ)$ corresponds to the area of fluctuations where small clusters fluctuate between superconducting and normal states owing to fluctuations of NUC occupation. The results may serve as important arguments in favor of the proposed model of HTSC.

description: Em Portugal, os projetos educativos das escolas foram concebidos como instrumentos de mobilização das comunidades educativas, capazes de influenciar o ensino e aprendizagem, mas, atualmente, seguem lógicas empresariais que esperam que as escolas sejam previsíveis. Contudo, as escolas são ambientes complexos, dados a imprevistos, o que requer instrumentos organizativos diferentes. Então, é necessário resolver este vazio teórico-prático e responder à questão: Como se constroem projetos educativos em escolas complexas? Fazemo-lo, sob a lente da Teoria da Complexidade que, por contradizer as expectativas de certeza e causalidade da modernidade, transtorna instrumentos em uso e reclama por métodos diferentes. Aqui analisamos os seus impactos da complexidade na construção de projetos educativos e convocamos as diferenças entre os sistemas ordenados (como as empresas) e os sistemas complexos (como as escolas) para apresentar a estrutura que deve presidir à construção de projetos educativos em ambientes complexos: circunstâncias (em vez de diagnósticos), experiências (em vez de atividades), histórias (em vez de metas) e coerência (em vez de visão). Concluímos que, no contexto da complexidade, as escolas requerem que se construam compromissos em vez de projetos educativos.

Optimal development of teenage mothers: a new look at an old issue
Creators: name: Pellatt, Kelly Lee
Publisher: name: University of British Columbia
Year: 2009

description: Adolescent pregnancy and parenting is a multifaceted issue that touches upon the very fabric that weaves together our social mores. Because of the perceived limitations teen parents place on their educational and economic futures, most research on adolescent pregnancy and parenting has focused on prevention. Research on teen mothers has shown that they are generally poor, have low levels of education, are prone to unstable relationships, and put their children at risk of being teen parents. Although teenage pregnancy prevention initiatives are important, they have (perhaps unknowingly) created a void in research and program development concerned with the well-being of adolescent mothers and their children. This study examines stereotypes directed toward teenage mothers (both historically and currently), relates both feminist and systems/ecological theory to teenage mothers, and undertakes reflective research on women who were teenage mothers. Twenty-one women who were teenage mothers (21 to 36 years old) participated in a reflective study addressing the relationship of three social support networks (family, community, and peers) to their level of education, economic well-being, and personal contentment. The study used a self-administered questionnaire consisting of fifty-four closed-ended, quantitative questions and three open-ended qualitative questions. Results from the questionnaire indicate a lack of community acceptance and social support programs (access to education and childcare) available to teen mothers. Strong positive relationships between the age of the participants, level of education, and total annual income were also observed. Examination of Canadian census data reveals that decreases in teen pregnancy over the last 30 years are proportional to the reduction of the overall Canadian birth-rate. The Canadian census data also indicate that adolescents who live on their own tend to live in poverty, regardless of whether or not they are a teen mother. Hence it must be considered that many of the stereotypes projected upon teen mothers may represent demographic phenomena prevalent among youth. Although the sample size is small (21 participants) this study contributes to a better understanding of the needs of teen mothers and is a good stepping stone for further research.

Quanto ao método, participaram no estudo 276 professores do 1º Ciclo do Ensino Básico dos dois géneros. O instrumento de recolha de dados utilizado nesta investigação é um inquérito por questionário inspirado no Questionário de Olweus construído em 1989[1], mas adaptado pelos autores à população adulta em estudo. Após análise dos resultados, verificou-se que a maioria dos professores defende que é pertinente que a prevenção do bullying escolar se inicie no Ensino Pré-Escolar, uma parte reconhece existir algum instrumento/protocolo de atuação/sinalização para possíveis ocorrências de bullying entre crianças no estabelecimento de ensino onde exercem funções e a maioria, defende que aliar o lúdico (jogos didáticos) à educação pode funcionar como um instrumento de prevenção primária e sensibilização das crianças no Ensino Pré-Escolar, para a problemática. As informações obtidas neste estudo são encorajadoras para se proporem mudanças que contribuam para uma prevenção primária do bullying através do lúdico/jogo, pois quando bem elaborado e explorado, esta ferramenta pode constituir um recurso importante para desenvolver o conhecimento e habilidades, permitindo ao mesmo tempo às crianças adquirir autonomia e aprender a respeitar as regras, proporcionando momentos de comunicação, encorajamento e atitudes positivas e corretas perante os outros. [1] Em 1982 os jornais da Noruega noticiaram o suicídio de três adolescentes associados a graves episódios de vitimização na escola, o que impulsionou o Psicólogo Dan Olweus, docente da Universidade de Bergen, a aprofundar as suas investigações acerca do bullying, tendo para tal construído um questionário em 1989, direcionado para crianças e jovens, que ao longo dos tempos veio a ser aplicado e adaptado por diversos investigadores desta temática, uma vez que a mesma continua a ser um fenómeno pejorativo nas relações sociais em meio escolar e por isso intemporal.

description: The $p$-stage Quantum Approximate Optimization Algorithm (QAOA$_p$) is a promising approach for combinatorial optimization on noisy intermediate-scale quantum (NISQ) devices, but its theoretical behavior is not well understood beyond $p=1$. We analyze QAOA$_2$ for the maximum cut problem (MAX-CUT), deriving a graph-size-independent expression for the expected cut fraction on any $D$-regular graph of girth $> 5$ (i.e. without triangles, squares, or pentagons). We show that for all degrees $D \ge 2$ and every $D$-regular graph $G$ of girth $> 5$, QAOA$_2$ has a larger expected cut fraction than QAOA$_1$ on $G$. However, we also show that there exists a $2$-local randomized classical algorithm $A$ such that $A$ has a larger expected cut fraction than QAOA$_2$ on all $G$. This supports our conjecture that for every constant $p$, there exists a local classical MAX-CUT algorithm that performs as well as QAOA$_p$ on all graphs.

description: Este texto parte da seguinte indagação: Como as Tecnologias da Informação e Comunicação (TIC) podem auxiliar no desenvolvimento de uma Educação Ambiental Crítica (EAC)? Assim, possui o objetivo de realizar uma reflexão sobre o modo como EAC e TIC se interligam diante dos novos desafios que se apresentam à educação, a partir da perspectiva trazida pelos projetos criativos ecoformadores (PCE). Para isso, optou-se por uma metodologia de abordagem qualitativa desenvolvida em uma uma pesquisa bibliográfica. Alguns dos autores que basearam a discussão são Freire (1984; 1989; 1996), Morin (2000), Layrargues (2020), Torre (2013), Torre & Zwierewicz (2009) e Moraes (1996, 2004, 2019). No decorrer do estudo, observou-se que as TIC, ao mesmo tempo em que são tradicionalmente utilizadas para aprofundar desigualdades e manter os interesses capitalistas, têm potencial para gerar uma reflexão contínua, individual e coletiva em direção à tomada de posicionamento crítico frente à presença e à atuação do ser humano no planeta, possibilitando que o ser humano conecte-se com o ser e estar no mundo e favorecendo o desenvolvimento da EAC. A metodologia dos PCE possui grande potencial para isso, pois viabiliza um ensino que aproxima o individual e o coletivo, possibilitando ao aluno encontrar-se em meio à complexidade do mundo e atuar sobre ela movido por uma consciência planetária. Assim, favorece um uso educacional das tecnologias aliado ao autoconhecimento e às vivências dos sujeitos. Para isso, é necessária uma profunda mudança de paradigmas em toda a sociedade e na educação, superando-se o uso excessivamente tecnicista das TIC.

description: Charged fluids rotating around compact objects can form unique equilibrium structures when ambient large-scale electromagnetic fields combine with strong gravity. Equatorial as well as off-equatorial toroidal structures are among such figures of equilibrium with a direct relevance for astrophysics. To investigate their geometrical shapes and physical properties in the near-horizon regime, where effects of general relativity play a significant role, we commonly employ a scheme based on the energy-momentum conservation written in a standard representation. Here, we develop its interesting alternatives in terms of two covariant force representations, both based on a hypersurface projection of the energy-momentum conservation. In a proper hypersurface, space-like forces can be defined, following from a decomposition of the fluid four-acceleration. Each of the representations provides us with an insight into properties of the fluid flow, being well reflected in related conformal hypersurface geometries; we find behaviour of centrifugal forces directly related to geodesics of these conformal hypersurfaces and their embedding diagrams. We also reveal correspondence between the charged fluid flow world-lines from an ordinary spacetime, and world-lines determined by a charged test particles equation of motion in a conformal spacetime.

description: Molecular spintronics hinges on the detailed understanding of electronic and magnetic properties of molecules interfaced with various materials. Here we demonstrate with ab-initio simulations that the prototypical Co-phthalocyanine (CoPc) molecule can surprisingly develop multi-spin states once deposited on the two-dimensional 2H-NbSe$_2$ layer. Conventional calculations based on density functional theory (DFT) show the existence of low, regular and high spin states, which reduce to regular and high spins states once correlations are incorporated with a DFT+$U$ approach. Depending on $U$, the ground state is either the low spin or high spin state with energy differences affected by the molecular orientation on top of the substrate. Our results are compared to recent scanning probe measurements and motivate further theoretical and experimental studies on the unveiled rich multi-magnetic behavior of CoPc molecule.
The giant H-alpha/X-ray filament in the cluster of galaxies A1795

description: The cluster of galaxies A1795 hosts a 46 kpc-long filament at its core, which is clearly visible in the light of H-alpha and X-ray emission. We present optical slit spectroscopy and deeper Chandra X-ray data of the filament. The optical spectra reveal that the the bulk of the filament is quiescent (with sigma < 130 km/s), although considerable velocity structure is apparent around the powerful radio source in the central cluster galaxy, where a direct interaction is occurring between the radio plasma and the surrounding intracluster medium. The filament contains a clump of UV/blue continuum halfway along its length, which we resolve into a chain of at least 5 distinct knots using archival HST images; the optical spectrum of this clump confirm it to be mostly comprised of O stars. It is well-removed from the central galaxy and radio source, and is most likely an example of a group of young star clusters condensing directly from the cooling gas in the filament. The observed spatial offset between these knots of star formation and the peak in the optical line emission confirms that the massive star formation is most unlikely to be responsible for the bulk of the observed emission-line luminosity in the filament. Some other (as yet undetermined) source of energy is required to power and maintain the optical line-emission, yet it must not completely impede the cooling of the X-ray gas within the filament to form the star clusters.

Günther Anders’ Theory of Media and Communication: Developing a Conception of Technological Domination, Alienation and Ideology with Marx beyond Marx
Creators: name: Marino, Oliver
Publisher: name: University of Westminster
Year: 2021

description: In this thesis, I contribute to the emergent English-language scholarship on little-known 20th century German-Austrian philosopher Günther Anders (1902-1992), whose work is unique for its critical focus on technology. Anders studied under Husserl and Heidegger and was Hannah Arendt’s first husband. He also knew members of the Frankfurt School such as Marcuse and Adorno. However, he gained little notoriety during most of his life and has been described as an outsider of philosophy. In 1936, Anders fled Europe for the United States to escape Nazi persecution owing to his Jewish heritage. He returned to Vienna in the 1950s and dedicated the second half of his life to the struggle against nuclear weapons and the Vietnam War. In this thesis I argue that, despite often being associated with Heidegger, Anders’ experience of the Second World War led him to undergo an epistemological break. He turned away from Heidegger and towards Marx. Anders can therefore be viewed as a humanist-Marxist. His work updates Marx’s view of domination, alienation and ideology, applying it to the question of industrial warfare, nuclear annihilation and post-war consumer technologies. I show how aspects of contemporary digital societies illustrate Anders’ critical theory of technology. I choose two case studies: military drones and dating apps. I show that Anders’ theory can help us understand how these technologies are involved in modern forms of domination, alienation and ideology. I do this by using critical discourse analysis (CDA) to evaluate the written and spoken accounts of military drone operators. I moreover conduct 18 semi-structured interviews with dating app users, which I equally analyse using CDA. According to Anders, modern technologies allowed humans to act absent-mindedly without identifying with the consequences of these actions. This meant that terrible atrocities could be committed without the accompanying moral feelings of empathy and regret. I show how military drone operators and dating app users equally convey the sense of a conflicted identification with their own actions. However, I derive the concept of technological splitting to update Anders’ concept of Promethean shame. With technological splitting affects are not absent but expressed in a raw, overtly direct fashion. They can consequently be compartmentalised and split off from operators' and users' sense of self.
Pre-critical Phenomena of Two-flavor Color Superconductivity in Heated Quark Matter -- diquark-pair fluctuations and non-Fermi liquid behavior --

description: We investigate the fluctuations of the diquark-pair field and their effects on observables above the critical temperature $T_c$ in two-flavor color superconductivity (CSC) at moderate density using a Nambu-Jona-Lasinio-type effective model of QCD. Because of the strong-coupling nature of the dynamics, the fluctuations of the pair field develop a collective mode, which has a prominent strength even well above T_c. We show that the collective mode is actually the soft mode of CSC. We examine the effects of the pair fluctuations on the specific heat and the quark spectrum for T above but close to T_c. We find that the specific heat exhibits singular behavior because of the pair fluctuations, in accordance with the general theory of second-order phase transitions. The quarks display a typical non-Fermi liquid behavior, owing to the coupling with the soft mode, leading to a pseudo-gap in the density of states of the quarks in the vicinity of the critical point. Some experimental implications of the precursory phenomena are also discussed.
