La farmacologia dello spirito di Bernard Stiegler di fronte all'arte cinematografica
Creators: name: Fanciullacci, Riccardo
Publisher: name: Trópos
Year: 2024

description: The richest reflections devoted to cinema by Bernard Stiegler precede his elaboration of the concept of pharmacology. This paper, however, aims to reconstruct those reflections as a pharmacological examination of the art of film. Firstly, it is clarified what a pharmacological examination is for Stiegler. Much attention is devoted here to criticizing and proposing a possible correction of the normative assumptions of Stiegler’s theory. Secondly, the “neganthropic” potentialities that, according to Stiegler, cinema possesses even though today, for the most part, audiovisual technology has been taken over by capitalism, with the resulting toxic effects, are examined.

description: We examine the dual of the so-called "hit problem", the latter being the problem of determining a minimal generating set for the cohomology of products of infinite projective spaces as module over the Steenrod Algebra $\mathcal{A}$ at the prime 2. The dual problem is to determine the set of $\mathcal {A}$-annihilated elements in homology. The set of $\mathcal{A}$-annihilateds has been shown by David Anick to be a free associative algebra. In this note we prove that, for each $k \geq 0$, the set of {\it $k$ partially $\mathcal{A}$-annihilateds}, the set of elements that are annihilated by $Sq^i$ for each $i\leq 2^k$, itself forms a free associative algebra.

description: The foaming properties, foaming capacity and foam stability, of soluble complexes of pectin and a globular protein, napin, have been investigated with a "Foamscan" apparatus. Complementary, we also used SANS with a recent method consisting in an analogy between the SANS by foams and the neutron reflectivity of films to measure in situ film thickness of foams. The effect of ionic strength, of protein concentration and of charge density of the pectin has been analysed. Whereas the foam stability is improved for samples containing soluble complexes, no effect has been noticed on the foam film thickness, which is almost around 315 Å whatever the samples. These results let us specify the role of each specie in the mixture: free proteins contribute to the foaming capacity, provided the initial free protein content in the bulk is sufficient to allow the foam formation, and soluble complexes slow down the drainage by their presence in the Plateau borders, which finally results in the stabilisation of foams.

description: We study left-invariant conformal Killing $2$- or $3$-forms on simply connected $2$-step nilpotent Riemannian Lie groups. We show that if the center of the group is of dimension greater than or equal to 4, then every such form is automatically coclosed (i.e. it is a Killing form). In addition, we prove that the only Riemannian 2-step nilpotent Lie groups with center of dimension at most 3 and admitting left-invariant non-coclosed conformal Killing $2$- and $3$-forms are: the Heisenberg Lie groups and their trivial 1-dimensional extensions, endowed with any left-invariant metric, and the simply connected Lie group corresponding to the free 2-step nilpotent Lie algebra on 3 generators, with a particular 1-parameter family of metrics. The explicit description of the space of conformal Killing $2$- and $3$-forms is provided in each case.

658.4: Leitendes Management

description: Die E-Government-Strategie Schweiz definiert drei Ziele: [1] Die Unternehmen nutzen für ihren Verkehr mit der öffentlichen Verwaltung die elektronischen Möglichkeiten. [2] Die Bevölkerung kann häufige oder mit grossem Aufwand verbundene Geschäfte mit den Behörden direkt auf elektronischem Weg abwickeln. [3] Die Behörden haben ihre Geschäftsprozesse modernisiert und verkehren untereinander elektronisch. Um diese Ziele erreichen zu können, müssen im Rahmen des Geschäftsprozessmanagements die öffentlichen Leistungen und Prozesse systematisch und einheitlich dokumentiert werden. Über das Geschäftsprozessmanagement lassen sich beispielsweise Produktions-, Vertriebs- und Kommunikationsaspekte unter Berücksichtigung des Prozessdesigns thematisieren und Verbindungen und Integrationen von verschiedensten internen Verwaltungsprozessen zu einem öffentlichen Verwaltungsprozess konfigurieren. Im Rahmen seiner Ziele 2012 – 2015 für den Bereich E-Government verfolgt das Staatssekretariat für Wirtschaft (SECO) die Absicht, die für die Schweizer Wirtschaft vorrangigen Behördenleistungen harmonisiert, vereinfacht und online verfügbar zu machen. Innerhalb dieser Aktivitäten besteht eine der Handlungslinien des SECO darin, dezentral verwaltete Inhalte, Dienste, Methoden und Werkzeuge über eine Datendrehscheibe zu vernetzen und zentral zur Verfügung zu stellen. Zu diesem Zweck wurde auch das Vorhaben „B1.13 „eCH-Prozessaustauschplattform für Gemeinden und Kantone“ lanciert, welches sich unter anderem an folgendem Zielzustand2 orientiert: [1] Auf der eCH Prozessaustauschplattform werden schweizweit Prozessbeschreibungen von Gemeinden und Kantonen publiziert und ausgetauscht. [2] Die Gemeinden und Kantone dokumentieren ihre Prozesse nach eCH-Standards und publizieren diese auf der eCH-Plattform. [3] Behörden nutzen die Prozessbeschreibungen der eCH-Plattform und können dadurch rasch und kostengünstig ihre eigenen Prozesse einheitlich dokumentieren, anpassen und pflegen. Die eCH-Prozessaustauschplattform und andere Prozessaustauschplattformen, wie sie zurzeit in Deutschland und der Schweiz bzw. in verschiedenen Kantonen realisiert oder geplant werden, könnten auch dazu beitragen, Geschäftsprozesse in Gemeinden und Kantonen zu vereinheitlichen.

description: The burgeoning fields of quantum computing and quantum key distribution have created a demand for a quantum memory. The gradient echo memory scheme is a quantum memory candidate for light storage that can boast efficiencies approaching unity, as well as the flexibility to work with either two or three level atoms. The key to this scheme is the frequency gradient that is placed across the memory. Currently the three level implementation uses a Zeeman gradient and warm atoms. In this paper we model a new gradient creation mechanism - the ac Stark effect - to provide an improvement in the flexibility of gradient creation and field switching times. We propose this scheme in concert with a move to cold atoms (~1 mK). These temperatures would increase the storage times possible, and the small ensemble volumes would enable large ac Stark shifts with reasonable laser power. We find that memory bandwidths on the order of MHz can be produced with experimentally achievable laser powers and trapping volumes, with high precision in gradient creation and switching times on the order of nanoseconds possible. By looking at the different decoherence mechanisms present in this system we determine that coherence times on the order of 10s of milliseconds are possible, as are delay-bandwidth products of approximately 50 and efficiencies over 90%.

description: We have carried out 12CO(J =2-1) and 12CO(J =3-2) observations at spatial resolutions of 1.0-3.8 pc toward the entirety of loops 1 and 2 and part of loop 3 in the Galactic center with NANTEN2 and ASTE. These new results revealed detailed distributions of the molecular gas and the line intensity ratio of the two transitions, R3-2/2-1. In the three loops, R3-2/2-1 is in a range from 0.1 to 2.5 with a peak at ~ 0.7 while that in the disk molecular gas is in a range from 0.1 to 1.2 with a peak at 0.4. This supports that the loops are more highly excited than the disk molecular gas. An LVG analysis of three transitions, 12CO J =3-2 and 2-1 and 13CO J =2-1, toward six positions in loops 1 and 2 shows density and temperature are in a range 102.2 - 104.7 cm-3 and 15-100 K or higher, respectively. Three regions extended by 50-100 pc in the loops tend to have higher excitation conditions as characterized by R3-2/2-1 greater than 1.2. The highest ratio of 2.5 is found in the most developed foot points between loops 1 and 2. This is interpreted that the foot points indicate strongly shocked conditions as inferred from their large linewidths of 50-100 km s-1, confirming the suggestion by Torii et al. (2010b). The other two regions outside the foot points suggest that the molecular gas is heated up by some additional heating mechanisms possibly including magnetic reconnection. A detailed analysis of four foot points have shown a U shape, an L shape or a mirrored-L shape in the b-v distribution. It is shown that a simple kinematical model which incorporates global rotation and expansion of the loops is able to explain these characteristic shapes.

Ermeneutica dell'umano, ovvero la tecnica
Creators: name: Ciarrapica, Carlotta
Publisher: name: Trópos
Year: 2024

description: Starting from some categories of Bernard Stiegler's thought and drawing on some passages from the book Technics and Time 1: The Fault of Epimetheus, this contribution aims to address the question of the relationship between the human and technology as an original and hermeneutic relationship, capable of deciphering the unique characteristics of these two actors. Two focal points form the basis of the reasoning: Stiegler's interpretation of technology as "the unthought" by philosophy and the assertion that the question of the human is poorly posed, because the human as such does not exist; rather, we speak of the non-inhuman. If hermeneutics is the possibility of questioning the meaning of a trace (written, oral, embodied, digital...), that is, of unveiling its essence by giving it meaning, this work seeks to show how, in Stiegler's framework, this unveiling operation is what makes technology human and the human technological, in a lack of clear boundaries that allows for the expression of the hermeneutic aspect of the human, which is to say, technology in the dual meaning hypothesized.

description: The exploratory analysis developed in this paper relies on the hypothesis that each editor possesses some power in the definition of the editorial policy of her journal. Consequently if the same scholar sits on the board of editors of two journals, those journals could have some common elements in their editorial policies. The proximity of the editorial policies of two scientific journals can be assessed by the number of common editors sitting on their boards. A database of all editors of ECONLIT journals is used. The structure of the network generated by interlocking editorship is explored by applying the instruments of network analysis. Evidences have been found of a compact network containing different components. This is interpreted as the result of a plurality of perspectives about the appropriate methods for the investigation of problems and the construction of theories within the domain of economics.

description: Ohne die Transformation unserer Wirtschaft in eine nachhaltige Kreislaufwirtschaft werden wir die planetaren Grenzen weiter überschreiten, die Klimaziele verfehlen und die Ökosysteme schädigen. Deutschlands Politik hat sich in einem Flickenteppich aus Strategien und Gesetzen verfangen, aus dem eine echte Kreislaufwirtschaft nicht in der notwendigen Geschwindigkeit hervorgehen kann. Der Versuch, einer verschwenderischen Wirtschaft allein mit den Mitteln des Abfallrechts beizukommen, kann nicht glücken.
Nötig ist vielmehr eine ganzheitliche, übergeordnete deutsche Kreislaufwirtschaftsstrategie mit ambitionierten nationalen Zielen. Das vorliegende Papier will zeigen, was sich konkret verändern muss und welche Hebel es braucht, um die Kreislaufwirtschaft signifikant voranzubringen.
Es ist Zeit zu handeln. Innovative Ideen, Konzepte und Forderungen liegen auf dem Tisch. Sie machen es möglich, Deutschland auf eine zirkuläre Zukunft auszurichten, Rohstoffe und Materialien konsequent im Kreislauf zu führen und der Wirtschaft Planungssicherheit zu geben. Kreislaufwirtschaft ist Zukunftswirtschaft. Sie muss Kernthema einer neuen Regierung werden.

Making space : new aesthetics in the Masterworks Gallery at the UBC Museum of Anthropology
Creators: name: Balcombe, Erika
Publisher: name: University of British Columbia
Year: 2018

description: In the twenty-first century, museums are becoming increasingly interested in the immaterial—the affective and sensorial—qualities of exhibition spaces like sound, light, and movement. These expanding aesthetic qualities or ‘atmospheres’ offer new ways of communicating narratives, meaning, and value in the exhibition context. They can therefore be mobilized to honour Indigenous ways of presenting information, like storytelling, which also enriches audience experience. In effect, they have the potential to become atmospheres of reconciliation which foster new intercultural understanding, dialogue, and healing. This thesis aims to illuminate the relationship between space, objects, and people in museum exhibits and the processes that collaborative teams embark upon to curate and shape exhibition content, narratives, and the messages they communicate. I explore the system of staged arrangement of atmospheric components—light, colour, materiality, new media—in museum settings by considering the newly constructed Masterworks Gallery and its inaugural exhibit, In a Different Light: Reflecting on Northwest Coast Art, at the Museum of Anthropology (MOA) at the University of British Columbia, Vancouver. The significance of MOA’s twofold project—the design of a new gallery and the development of its first exhibit—is its potential for communicating institutional philosophies, priorities, and future goals in concrete form. My research will contribute to the fields of museology and design studies by illuminating how space and the sensorial might come together to create atmospheres of reconciliation using technology and new media not only as a product but also as a process. It will show how making space for multiple perspectives, through culturally diverse ways of remembering, communicating, researching, and learning, works toward advancing a decolonized methodology by challenging outdated museum prescripts and developing a new curatorial model. By claiming authority and space within the museum, Indigenous storytellers reclaim their right to self-definition and demonstrate ownership and authority over their own material and intangible cultures. By recalibrating sensory inputs in exhibits, like touch and voice, museums are building new kinds of connections, fostering understanding, and ultimately promoting reconciliation with Indigenous people through these new forms of aesthetic action.

description: In the need to find models to think about the relationship between hermeneutics and philosophy of technology this contribution intends to highlight the profound, if not constitutive, link that exists between hermeneutics, understood in a broad sense, and technology. The reading of two papers - Psyché. Invention de l’autre and No apocalypse, not now: à toute vitesse, sept missiles, septs missives - held by Jacques Derrida in 1984, at Cornell University, allows us to investigate in an original way, both the need to problematize differently the way of posing and understanding the relationship between the two terms, and to recognize the urgency and responsibility of thought, as an effective expression of a conscious taking of responsibility. Through Derrida, we can finally recognize the profound and inseparable intertwining between rhetoric and technology, between fabulous production and technical production.

description: Context: DevOps has become one of the fastest-growing software development paradigms in the industry. However, this trend has presented the challenge of ensuring secure software delivery while maintaining the agility of DevOps. The efforts to integrate security in DevOps have resulted in the DevSecOps paradigm, which is gaining significant interest from both industry and academia. However, the adoption of DevSecOps in practice is proving to be a challenge. Objective: This study aims to systemize the knowledge about the challenges faced by practitioners when adopting DevSecOps and the proposed solutions reported in the literature. We also aim to identify the areas that need further research in the future. Method: We conducted a Systematic Literature Review of 54 peer-reviewed studies. The thematic analysis method was applied to analyze the extracted data. Results: We identified 21 challenges related to adopting DevSecOps, 31 specific solutions, and the mapping between these findings. We also determined key gap areas in this domain by holistically evaluating the available solutions against the challenges. The results of the study were classified into four themes: People, Practices, Tools, and Infrastructure. Our findings demonstrate that tool-related challenges and solutions were the most frequently reported, driven by the need for automation in this paradigm. Shift-left security and continuous security assessment were two key practices recommended for DevSecOps. Conclusions: We highlight the need for developer-centered application security testing tools that target the continuous practices in DevSecOps. More research is needed on how the traditionally manual security practices can be automated to suit rapid software deployment cycles. Finally, achieving a suitable balance between the speed of delivery and security is a significant issue practitioners face in the DevSecOps paradigm.

description: Binding, lateral diffusion and exchange are fundamental dynamic processes involved in protein association with cellular membranes. In this study, we developed numerical simulations of lateral diffusion and exchange of fluorophores in membranes with arbitrary bleach geometry and exchange of the membrane localized fluorophore with the cytosol during Fluorescence Recovery after Photobleaching (FRAP) experiments. The model simulations were used to design FRAP experiments with varying bleach region sizes on plasma-membrane localized wild type GFP-Ras2 with a dual lipid anchor and mutant GFP-Ras2C318S with a single lipid anchor in live yeast cells to investigate diffusional mobility and the presence of any exchange processes operating in the time scale of our experiments. Model parameters estimated using data from FRAP experiments with a 1 micron x 1 micron bleach region-of-interest (ROI) and a 0.5 micron x 0.5 micron bleach ROI showed that GFP-Ras2, single or dual lipid modified, diffuses as single species with no evidence of exchange with a cytoplasmic pool. This is the first report of Ras2 mobility in yeast plasma membrane. The methods developed in this study are generally applicable for studying diffusion and exchange of membrane associated fluorophores using FRAP on commercial confocal laser scanning microscopes.

description: In autonomous applications for mobility and transport, a high-rate and highly accurate vehicle-state estimation is achieved by fusing measurements of global navigation satellite systems (GNSS) and inertial sensors. The state estimation and its protection-level generation often suffer from satellite-signal disturbances in urban environments and subsequent poor parametrization of the satellite observables. Thus, we propose an innovative scheme involving an extended H_infinity filter (EHF) for robust state estimation and zonotope for the protection-level generation. This scheme is shown as part of a tightly coupled navigation system based on an inertial navigation system and aided by the GPS/Galileo dual-constellation satellite navigation system. Specifically, GNSS pseudorange and deltarange observables are utilized. The experimental results of post-processing a real-world dataset show significant advantages of EHF against a conventional extended Kalman filter regarding the navigation accuracy and robustness under various GNSS-measurement parametrizations and environmental circumstances. The zonotope-based protection-level calculation is proven valid, computationally affordable, and feasible for real-time implementations.

description: An unprecedented amine-catalyzed stereoselective reaction of α,α-dicyanomethylidenecarbazoles with indane-1,3-dione and aryl/heteroaryl aldehydes afforded a series of indanedione-fused benzo[a]carbazoles. The plausible mechanism for the formation of the final products result from the above MCR is described based on successive Knoevenagel/Michael/nucleophilic reactions. The products were obtained in moderate to good yields without the use of any chromatographic techniques. The structures of the synthesized spirocycloadducts were confirmed by elemental analysis and spectral data (FT-IR, 1H NMR, and 13C NMR).

Understanding dating violence mental health outcomes in adolescents : age discrepancy and suicidality
Creators: name: Gesner, Heather
Publisher: name: University of British Columbia
Year: 2018

description: Purpose: Key mental health outcomes are associated with adolescent dating violence. In research examining adolescent dating violence and mental health outcomes, results vary between studies, and little research is from Canada. Current research seldom considers gender differences, and the link between dating violence and older romantic partners. This study investigated gender differences in mental health issues associated with past year dating violence among youth in British Columbia. I also analyzed the relationship between dating violence and age-discordant relationships (illegal older partner at first sex). Methods: I conducted an analysis using cross-sectional data from the 2013 BC Adolescent Health Survey (BC AHS; N=28,992). Measures included: past year suicidal ideation/attempts and self-harm behavior, past month extreme sadness and hopelessness, poor self-rated mental health, and self-reported post-traumatic stress disorder (PTSD) and depression diagnoses. I examined the relationship between dating violence and these mental health outcomes separately by gender. I analyzed these same measures by age-discordant relationships among those with a dating violence history for both boys and girls together, and then separately by gender. Results: Among the 39% of youth who reported being in a relationship, 5.9% reported experiencing dating violence, with similar prevalence for boys (6.3%) and girls (5.5%). Adolescent dating violence was associated with all mental health outcomes. Girls reported more adverse mental health outcomes than boys. Youth with dating violence were also more likely to report an age-discordant first relationship, and they were more likely to report poor/fair mental health, PTSD, and suicidality versus those whose first sexual partner was not illegally older. Among those with both dating violence and age discordant relationship history, boys were more likely to report poor/fair mental health; girls were more likely to report PTSD. Discussion and Implications: More girls than boys showed unfavourable mental health outcomes associated with dating violence. Results support past research showing a strong association between an older first sexual partner, dating violence and adverse mental health outcomes. Nurses in mental health services should regularly screen for dating violence in adolescent romantic relationships, for both boys and girls, which may exacerbate mental health illness.

description: Saudi Arabias rapid economic growth and social evolution under Vision 2030 present a unique opportunity to track emerging trends in real time. Uncovering trends in real time can open up new avenues for business and investment opportunities. This paper explores how AI and social media analytics can uncover and monitor these trends across sectors like sustainability, construction, food beverages industry, tourism, technology, and entertainment. This paper focus on use of AI-driven methodology to identify sustainability trends across Saudi Arabia. We processed millions of social media posts, news, blogs in order to understand sustainability trends in the region. The paper presents an AI approach that can help economists, businesses, government to understand sustainability trends and make better decisions around them. This approach offers both sector-specific and cross-sector insights, giving decision-makers a reliable, up to date snapshot of Saudi Arabias market shifts. Beyond Saudi Arabia, this framework also shows potential for adapting to other regions. Overall, our findings highlight how by using AI-methodologies, give decision makers a reliable method to understand how initiatives are perceived and adopted by the public and understand growth of trends.

description: Ziziphus mucronata is a medicinal plant used traditionally for treating various diseases. The antioxidant assay for the crude extracts obtained from the berries of Ziziphus mucronata was carried out using DPPH (2,2-diphenyl-1-picrylhydrazyl) method. Purified antioxidant compounds were obtained by chromatographic methods and were subjected to structure elucidation using nuclear magnetic resonance (NMR). Berries of Ziziphus mucronata were found to have high antioxidant activity since their ethyl acetate extract had an IC50 value of 214.9 µg/mL and methanol extract had an IC50 value of 8.9 µg/mL showing significant antioxidant activity in comparison to that of the standard ascorbic acid, which was found to have an IC50 value of 1.5 µg/mL. Betulin, betulinic acid and ursolic acid were among the compounds isolated from the berries of Ziziphus mucronata and are known to possess significant antioxidant activity. They have not been known to be previously isolated from Ziziphus mucronata.

description: The interactions of a E/A=70-MeV 9C beam with a Be target was used to populate levels in Be, B, and C isotopes which undergo decay into many-particle exit channels. The decay products were detected in the HiRA array and the level energies were identified from their invariant mass. Correlations between the decay products were examined to deduce the nature of the decays, specifically to what extent all the fragments were created in one prompt step or whether the disintegration proceeded in a sequential fashion through long-lived intermediate states. In the latter case, information on the spin of the level was also obtained. Of particular interest is the 5-body decay of the 8C ground state which was found to disintegrate in two steps of two-proton decay passing through the 6Beg.s. intermediate state. The isobaric analog of 8Cg.s. in 8B was also found to undergo two-proton decay to the isobaric analog of 6Beg.s. in 6Li. A 9.69-MeV state in 10C was found to undergo prompt 4-body decay to the 2p+2alpha exit channel. The two protons were found to have a strong enhancementin the diproton region and the relative energies of all four p-alpha pairs were consistent with the 5Lig.s. resonance.

description: In our search for anti-inflammatory constituents from Vietnamese plants, the methanolic extract of Helicteres viscida was found to exhibit inhibitory effect on LPS-induced NO production in RAW264.7 cells. Phytochemical investigation of this plant led to isolation of four sulphated flavones (1–4), including one new compound 5,3′,4′-trihydroxy-7-methoxy-8-O-sulphate flavone (1), and two pregnane-type steroids (5 and 6), including one new compound 7-epi-heligenin B (5). Their structures were elucidated by 1D and 2D NMR as well as HR-QTOF-MS experiments. Among isolated compounds, heligenin B (6) exhibited potent inhibitory effect on LPS-induced NO production in RAW264.7 cells with IC50 of 1.23 ± 0.05 µM. The activity of 6 was comparable to that of the positive control cardamonin.

description: A constant increase in the need of clean energy demands more innovation from the research community. Active and stable materials that can make use of the solar radiation to promote different reactions are the cornerstone of emerging technologies. Polymeric carbon nitrides that harvest solar radiation to drive electrochemical reactions are considered solid candidates. In this respect, polymeric carbon nitrides were prepared by the thermal polycondensation of melamine. As-obtained materials were characterized by synchrotron radiation and lab-based techniques. The electron band structure was fully characterized by a combined electrochemical optoelectronic study. Electron microscopy studies before and after the photoelectrochemical experiments showed morphological and structure degradation. The work at-hand concludes that polymeric carbon nitrides are prone to photoelectrochemical degradation at high overpotentials.

description: It is well known that three-qubit system has two kind of inequivalent genuine entangled classes under stochastic local operation and classical communication (SLOCC). These classes are called as GHZ class and W class. GHZ class proved to be a very useful class for different quantum information processing task such as quantum teleportation, controlled quantum teleportation etc. In this work, we distribute pure three-qubit states from GHZ class into different subclasses denoted by $S_{1}$, $S_{2}$, $S_{3}$, $S_{4}$ and show that the three-qubit states either belong to $S_{2}$ or $S_{3}$ or $S_{4}$ may be more efficient than the three-qubit state belong to $S_{1}$. Thus, it is necessary to discriminate the states belong to $S_{i}, i=2,3,4$ and the state belong to $S_{1}$. To achieve this task, we have constructed different witness operators that can classify the subclasses $S_{i}, i=2,3,4$ from $S_{1}$. We have shown that the constructed witness operator can be decomposed into Pauli matrices and hence can be realized experimentally.
