Feeding the city: food cycles and the production of urban space

Städte bilden Schnittpunkte in translokalen Güterflüssen und Versorgungssystemen. Insbesondere die Versorgung der Stadtbevölkerung mit Lebensmitteln ist – wie die Wasser- oder Energieversorgung – eine Grundvoraussetzung für das Funktionieren städtischer Lebensweisen. Sie prägt die Beziehungen von Städten zu ihrem Hinterland. In der Geschichte bildete die ständige Expansion der Landwirtschaft und der Mittel des Warentransports eine wesentliche Bedingung für städtisches Wachstum, und heute hat die Lebensmittelversorgung längst eine planetarische Dimension angenommen. Ihre Formen und Abläufe, wie auch die Rituale des Essens, haben sich seit Jahrhunderten in die Architektur der Städte eingeschrieben. Dennoch bleiben die Strukturen der Lebensmittelversorgung meist unter dem Radar der Stadtforschung und -planung. Im Seminar „Feeding the City“ haben wir uns mit den Lieferketten konventioneller Lebensmittel befasst, wie wir sie im Supermarkt oder Discounter in großer Zahl und zu niedrigen Preisen kaufen können: abgepacktes Fabrikbrot, H-Milch, Hähnchenbrust, Bananen oder Fruchtgummis. Wo kommen sie her, welchen Weg nehmen sie und wie formen sie die Räume, durch die sie zirkulieren? Welche Akteur*innen und Regularien bestimmen diese Vorgänge und Zusammenhänge? Studierende der Stadtplanung und Architektur der BTU Cottbus-Senftenberg haben zehn alltägliche Lebensmittel verfolgt: Vom Ort ihres Anbaus oder der Tierhaltung über die Stationen der Lebensmittelindustrie und Distribution bis hin zum Einzelhandel, dem privaten Kühlschrank oder Esstisch und zur Entsorgung der Überbleibsel. Anhand von Kartierungen und Netzwerkdiagrammen haben sie die räumliche Reichweite und die Komplexität der Lieferketten betrachtet, sie haben die gebauten Räume einzelner Stationen und ihre städtischen Kontexte analysiert und schließlich nach der aktuellen oder historischen Präsenz des jeweiligen Produkts in der Stadt Cottbus gefragt.Cities form intersections in translocal flows of goods and supply systems. Food supply shapes the relationships between cities and their hinterlands and is a basic prerequisite for the functioning of urban lifestyles. Throughout history, urban growth has been accompanied by the constant expansion of agriculture and transportation networks. By now, these expansive dynamics of food supply systems have reached planetary dimensions. Food supply and processing, as well as eating rituals have been inscribed in the architecture of cities for centuries. Yet, these complex supply systems have largely remained under the radar of urban planning and urban research. In the seminar "Feeding the City", we explored the supply chains of conventional food items, which are commonly found in large numbers and at low prices in supermarkets, such as packaged and sliced bread, UHT milk, chicken breast, bananas or fruit gums. We followed ten products and looked at the places where they are produced and processed, the routes they take, and how they shape the spaces through which they circulate. We also zoomed in on the actors, regulations and power relations that determine these processes and contexts. Students of urban planning and architecture at the BTU Cottbus-Senftenberg have set out on a (mostly virtual) journey to trace everyday foodstuffs from the places where they are grown or raised, to the supermarkets in Cottbus, Germany. Using various mapping methods and network diagrams, they have developed a set of maps that illustrate the wide reach of supply chains around the world, complex actor-networks within food systems, the architectures of particular stations as well as their urban context, and the current or historical presence of the respective products in the city of Cottbus

A search for top squarks with R-parity-violating decays to all-hadronic final states with the ATLAS detector in s√s = 8 TeV proton-proton collisions

A search for the pair production of top squarks, each with R-parity-violating decays into two Standard Model quarks, is performed using 17.4 fb−1 of s√=8s=8 TeV proton-proton collision data recorded by the ATLAS experiment at the LHC. Each top squark is assumed to decay to a b- and an s-quark, leading to four quarks in the final state. Background discrimination is achieved with the use of b-tagging and selections on the mass and substructure of large-radius jets, providing sensitivity to top squark masses as low as 100 GeV. No evidence of an excess beyond the Standard Model background prediction is observed and top squarks decaying to b¯¯s¯¯¯b¯s¯ are excluded for top squark masses in the range 100 ≤mt¯≤ 315100 ≤mt¯≤ 315 GeV at 95% confidence level

Search for Scalar Diphoton Resonances in the Mass Range 65−60065-600 GeV with the ATLAS Detector in pppp Collision Data at s\sqrt{s} = 8 TeVTeV

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using $20.3\text{}\text{}{\mathrm{fb}}^{-1}$ of $\sqrt{s}=8\text{}\text{}\mathrm{TeV}$ $pp$ collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs boson is treated as a background. No significant evidence for an additional signal is observed. The results are presented as limits at the 95% confidence level on the production cross section of a scalar boson times branching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerably wider mass range than previous searches

Search for Higgs and ZZ Boson Decays to J/ψγJ/\psi\gamma and Υ(nS)γ\Upsilon(nS)\gamma with the ATLAS Detector

A search for the decays of the Higgs and $Z$ bosons to $J/\psi\gamma$ and $\Upsilon(nS)\gamma$ ($n=1,2,3$) is performed with $pp$ collision data samples corresponding to integrated luminosities of up to $20.3\mathrm{fb}^{-1}$ collected at $\sqrt{s}=8\mathrm{TeV}$ with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above expected backgrounds and 95% CL upper limits are placed on the branching fractions. In the $J/\psi\gamma$ final state the limits are $1.5\times10^{-3}$ and $2.6\times10^{-6}$ for the Higgs and $Z$ bosons, respectively, while in the $\Upsilon(1S,2S,3S)\,\gamma$ final states the limits are $(1.3,1.9,1.3)\times10^{-3}$ and $(3.4,6.5,5.4)\times10^{-6}$, respectively

Measurements of the Total and Differential Higgs Boson Production Cross Sections Combining the H??????? and H???ZZ*???4??? Decay Channels at s\sqrt{s}=8??????TeV with the ATLAS Detector

Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3~fb$^{-1}$ of $pp$ collisions produced by the Large Hadron Collider at a center-of-mass energy of $\sqrt{s} = 8$ TeV and recorded by the ATLAS detector. Cross sections are obtained from measured $H \rightarrow \gamma \gamma$ and $H \rightarrow ZZ ^{*}\rightarrow 4\ell$ event yields, which are combined accounting for detector efficiencies, fiducial acceptances and branching fractions. Differential cross sections are reported as a function of Higgs boson transverse momentum, Higgs boson rapidity, number of jets in the event, and transverse momentum of the leading jet. The total production cross section is determined to be $\sigma_{pp \to H} = 33.0 \pm 5.3 \, ({\rm stat}) \pm 1.6 \, ({\rm sys}) \mathrm{pb}$. The measurements are compared to state-of-the-art predictions.Measurements of the total and differential cross sections of Higgs boson production are performed using 20.3  fb-1 of pp collisions produced by the Large Hadron Collider at a center-of-mass energy of s=8  TeV and recorded by the ATLAS detector.

Finska tingsdomares bedömningar av partsutlåtanden givna på plats i rätten eller via videokonferens

Professionals within the judicial system sometimes believe they can assess whether someone is lying or not based on cues such as body language and emotional expression. Research has, however, shown that this is impossible. The Finnish Supreme Court has also given rulings in accordance with this demonstrated fact. There has also been previous research on whether party or witness statements are assessed differently in court depending on whether they are given live, via videoconference, or via prerecorded video. In the present study, we investigated how a Finnish sample of district judges (N=47) assigned probative value to different variables concerning the statement or the statement giver, such as body language and emotional expression. We also investigated the connection between the judges’ beliefs about the relevance of body language and emotional expression and their preference for live statements or statements via videoconference. The judges reported assigning equal amounts of probative value to statements given live and statements given via videoconference. However, judges found it easier to detect deception live, and this preference correlated with how relevant they thought body language is when assessing the probative value of the statement. In other words, a slight bias to assess live statements more favorably than statements given via videoconference might still exist. More effort needs to be put into making judges and Supreme Courts aware of robust scientific results that have been the subject of decades of research, such as the fact that one cannot assess whether someone is lying or not based on cues such as body language
