description: Covariation of plant functional traits, that is, phenotypic integration, might constrain their variability. This was observed for inter- and intraspecific variation, but there is no evidence of a relationship between phenotypic integration and the functional variation within single plants (within-individual trait variation; WTV), which could be key to understand the extent of WTV in contexts like plant–plant interactions. We studied the relationship between WTV and phenotypic integration in c. 500 trees of 21 species in planted forest patches varying in species richness in subtropical China. Using visible and near-infrared spectroscopy (Vis-NIRS), we measured nine leaf morphological and chemical traits. For each tree, we assessed metrics of single and multitrait variation to assess WTV, and we used plant trait network properties based on trait correlations to quantify phenotypic integration. Against expectations, strong phenotypic integration within a tree led to greater variation across leaves. Not only this was true for single traits, but also the dispersion in a tree's multitrait hypervolume was positively associated with tree's phenotypic integration. Surprisingly, we only detected weak influence of the surrounding tree-species diversity on these relationships. Our study suggests that integrated phenotypes allow the variability of leaf phenotypes within the organism and supports that phenotypic integration prevents maladaptive variation.

description: We present a systematic study of the influence of different forcing types on the statistical properties of supersonic, isothermal turbulence in both the Lagrangian and Eulerian frameworks. We analyse a series of high-resolution, hydrodynamical grid simulations with Lagrangian tracer particles and examine the effects of solenoidal (divergence-free) and compressive (curl-free) forcing on structure functions, their scaling exponents, and the probability density functions of the gas density and velocity increments. Compressively driven simulations show a significantly larger density contrast, a more intermittent behaviour, and larger fractal dimension of the most dissipative structures at the same root mean square Mach number. We show that the absolute values of Lagrangian and Eulerian structure functions of all orders in the integral range are only a function of the root mean square Mach number, but independent of the forcing. With the assumption of a Gaussian distribution for the probability density function of the velocity increments on large scales, we derive a model that describes this behaviour.

description: The possibility of having artificial agents that can interact with humans and learn completely new tasks through instruction and demonstration is an exciting prospect. This is the goal of the emerging research area of Interactive Task Learning. Solving this problem requires integrating many capabilities across AI to create general robot learns that can operate in a variety of environments. One particular challenge is that the space of possible tasks is extremely large and varied. Developing approaches that cover this space is a difficult challenge, made more so by having to learn from a limited, though high-quality, number of examples given through interaction with a teacher. In this dissertation, we identify three major dimensions of task complexity (diverse types of actions, task formulations, and task modifiers), and describe extensions that demonstrate greater learning capabilities for each dimension than previous work. First, we extend the representations and learning mechanism for innate tasks so the agent can learn tasks that utilize many different types of actions beyond physical object manipulation, such as communication and mental operations. Second, we implement a novel goal-graph representation that supports both goal-based and procedural tasks. Thus the instructor can formulate a task as achieving a goal and let the agent use planning to execute it, or can formulate the task as executing a procedure, or sequence of steps, when it is not easy to define a goal. This also allows interesting cases of a task that blends elements of a procedure and goal. Third, we added support for learning subtasks with various modifying clauses, such as temporal constraints, conditions, or looping structures. Crucially, we show that the agent can learn and generalize a canonical version of a task and then combine it with these various modifiers within a task hierarchy without requiring additional instruction. This is done in the context of Rosie -- an agent implemented within the Soar cognitive architecture that can learn completely new tasks in one shot through situated interactive instruction. By leveraging explanation-based generalization and domain knowledge, the agent quickly learns new hierarchical tasks, including their structure, arguments, goals, execution policies, and task decompositions, through natural language instruction. It has been used with various robotic platforms, though most of the learning demonstrations and evaluations in this work use a simulated mobile robot in a multi-room, partially-observable environment. In the end, we show that the agent can combine all of these extensions while learning complex hierarchical tasks that cover extended periods of time and demonstrate significant flexibility.

description: We discuss designer Hamiltonians---lattice models tailored to be free from sign problems ("de-signed") when simulated with quantum Monte Carlo methods but which still host complex many-body states and quantum phase transitions of interest in condensed matter physics. We focus on quantum spin systems in which competing interactions lead to non-magnetic ground states. These states and the associated quantum phase transitions can be studied in great detail, enabling direct access to universal properties and connections with low-energy effective quantum field theories. As specific examples, we discuss the transition from a Neel antiferromagnet to either a uniform quantum paramagnet or a spontaneously symmetry-broken valence-bond solid in SU(2) and SU(N) invariant spin models. We also discuss anisotropic (XXZ) systems harboring topological Z2 spin liquids and the XY* transition. We briefly review recent progress on quantum Monte Carlo algorithms, including ground state projection in the valence-bond basis and direct computation of the Renyi variants of the entanglement entropy.

description: Transkulturalität ist ein gesellschaftliches Phänomen, das zunehmend an Bedeutung für die Identitätsbildung von Menschen gewinnt und somit eine Herausforderung für Schule und Lehrerbildung auch im Sachunterricht darstellt: Auf konzeptionell curricularer wie didaktisch-methodischer Ebene weisen die Grundannahmen zur Transkulturalität über bisherige Konzepte interkulturellen Lernens im Sachunterricht hinaus. Transkulturalität ist bislang nicht in ihrer Komplexität theoretisch oder empirisch vollständig erfasst. Eine Übertragung auf pädagogische Zusammenhänge ist allerdings auf forschungsbasierte Erkenntnisse angewiesen, um zu angemessenen Überlegungen für die Praxis zu kommen.Im folgenden Beitrag werden zunächst die wesentlichen Grundannahmen zur Transkulturalität in ihrer Bedeutung für das Individuum dargelegt. Im Anschluss daran wird eine empirische Untersuchung vorgestellt, die sich mit transkultureller Identitätsbildung von Studierenden in pädagogischen Studiengängen beschäftigt. Der Ausblick zeigt kurz Konsequenzen für die universitäre Lehrerbildung im Sachunterricht sowie Möglichkeiten weiterführender Forschung auf.

description: We performed the photometric B, V and R observations of nine disk galaxies that were suspected in having abnormally low total mass-to-light (M/L) ratios for their observed color indices. We use our surface photometry data to analyze the possible reasons for the anomalous M/L. We infer that in most cases this is a result of errors in photometry or rotational velocity, however for some galaxies we cannot exclude the real peculiarities of the galactic stellar population. The comparison of the photometric and dynamical mass estimates in the disk shows that the low M/L values for a given color of disks are probably real for a few our galaxies: NGC 4826 (Sab), NGC 5347 (Sab), and NGC 6814 (Sb). The small number of such galaxies suggests that the stellar initial mass function is indeed universal, and that only a small fraction of galaxies may have a non-typical low-mass star depleted initial mass function. Such galaxies require more careful studies for understanding their star formation history.

description: This exploratory study uses a cultural capital framework to examine the critical issue of goal alignment between parent and student expectations in predicting postsecondary matriculation. Addressing cultural capital in terms of functional specificity, the research expands and contributes to the related literature by focusing particularly on aligned ambitions and by delving deeper into the documented "action steps" taken by students to reach their stated postsecondary goals. Also, by separating two- and four-year college enrollment outcomes, clear differences are revealed among student expectations and action steps relative to overall college matriculation and educational attainment goals

description: Spontaneous breaking of chiral symmetry is investigated in the Hamiltonian approach to QCD in Coulomb gauge. The quark wave functional is determined by the variational principle using an ansatz which goes beyond the commonly used BCS-type of wave functionals and includes the coupling of the quarks to the transversal spatial gluons. Using the lattice gluon propagator as input it is shown that the low energy chiral properties of the quarks, like the quark condensate and the constituent quark mass, are substantially increased by the coupling of the quarks to the spatial gluons. Our results compare favourably with the phenomenological values.

description: Für einen Großteil der Kinder in Deutschland ist der Computer zum festen Bestandteil ihres Lebens geworden (vgl. Scholz 2001, S. 32; Gervé 1998, S. 196). Einer Umfrage des Medienpädagogischen Forschungsverbunds Südwest (2003) zufolge wachsen Sechs- bis 13-Jährige immer stärker in Haushalten auf, die mit Computer und Internet ausgestattet sind. 2003 verfügten 74% der befragten Haushalte über einen Computer und 57% über einen Internetzugang. Bereits 70% der befragten Sechs- bis 13-Jährigen in Deutschland haben erste Erfahrungen mit dem Computer sammeln können, 60% davon nutzen auch das Internet1 (vgl.: http://www.mpfs.de /studien/kim/kim03.html).Auch immer mehr Grundschulen sind mit Computern ausgestattet. So verfügen mehr als drei Viertel aller Grundschulen in Deutschland über mindestens einen Computer und davon wiederum drei Viertel über einen Internetanschluss (vgl. Aufenanger 2003, S. 2).Der Einsatz des Computers im Unterricht ist allerdings umstritten. Für Kritiker wie Hartmut von Hentig geht es nicht darum, wie der Computer im Unterricht eingesetzt werden kann, sondern ob er im Unterricht überhaupt seine Berechtigung hat. Hentig spricht von einem „allmählichen Verschwinden der Wirklichkeit“. Die Nutzung des Computers geht für ihn mit einem Verlust an Primärerfahrung einher. Weiterhin befürchtet er, dass der Computer den Lehrer überflüssig macht (vgl. Mitzlaff 1996, S. 28ff.). Hentigs Befürchtungen möchte ich in meiner Arbeit widerlegen.

description: Die Formulierung „Ordnungen des Anderen“ führt mitten hinein in ein Gestrüpp von Unklarheiten, die sich ergeben, wenn man das Verhältnis der Begriffe das „Eigene“ und das „Fremde“ mit dem zweiten Blick betrachtet, dem analytischen. Auf den ersten Blick, dem der kulturellen bzw. didaktischen Praxis, ist scheinbar nichts klarer als diese Begriffe. Das ergibt sich aus der Tradition, in der gerade auch der Sachunterricht steht. Es geht doch eigentlich immer darum, dass Kinder lernen, sich das „anzueignen“ – als Wissen, Können oder Einstellung – was sie noch nicht gelernt haben, so dass sie dann über die Welt, die Natur, die Gesellschaft in gewisser Hinsicht „verfügen“ können, wenigstens sprachlich. Das aber täuscht leicht darüber hinweg, dass es zugleich um eine andere Verfügung geht, darum nämlich, dass in diesen inszenierten Lehr-Lern-Prozessen die Kinder „verfügbar“ gemacht werden durch Bildung und Erziehung; und diese Verfügbarkeit soll möglichst wie selbstverständlich funktionierend abrufbar sein für die Anforderungen der Gesellschaft, als Arbeitwilligkeit, als Ethik, als Ästhetik und neuerdings als „Nachhaltigkeit“. Die Welt, die sich Kinder aneignen sollen, damit sie in ihr richtig von selbst funktionieren, wird von außen (durch Politik, Wissenschaft, Didaktik) definiert ebenso wie die Methoden, die Kinder lernen, um selbst zu lernen. Was ist da das Eigene und was das Fremde?

description: In non-equilibrium Green's function calculations the use of the Generalized Kadanoff-Baym Ansatz (GKBA) allows for a simple approximate reconstruction of the two-time Green's function from its time-diagonal value. With this a drastic reduction of the computational needs is achieved in time-dependent calculations, making longer time propagation possible and more complex systems accessible. This paper gives credit to the GKBA that was introduced 25 years ago. After a detailed derivation of the GKBA, we recall its application to homogeneous systems and show how to extend it to strongly correlated, inhomogeneous systems. As a proof of concept, we present results for a 2-electron quantum well, where the correct treatment of the correlated electron dynamics is crucial for the correct description of the equilibrium and dynamic properties.

description: (1) Background: Kidney and cardiovascular diseases are responsible for a large fraction of population morbidity and mortality. Early, targeted, personalized intervention represents the ideal approach to cope with this challenge. Proteomic/peptidomic changes are largely responsible for the onset and progression of these diseases and should hold information about the optimal means of treatment and prevention. (2) Methods: We investigated the prediction of renal or cardiovascular events using previously defined urinary peptidomic classifiers CKD273, HF2, and CAD160 in a cohort of 5585 subjects, in a retrospective study. (3) Results: We have demonstrated a highly significant prediction of events, with an HR of 2.59, 1.71, and 4.12 for HF, CAD, and CKD, respectively. We applied in silico treatment, implementing on each patient’s urinary profile changes to the classifiers corresponding to exactly defined peptide abundance changes, following commonly used interventions (MRA, SGLT2i, DPP4i, ARB, GLP1RA, olive oil, and exercise), as defined in previous studies. Applying the proteomic classifiers after the in silico treatment indicated the individual benefits of specific interventions on a personalized level. (4) Conclusions: The in silico evaluation may provide information on the future impact of specific drugs and interventions on endpoints, opening the door to a precision-based medicine approach. An investigation into the extent of the benefit of this approach in a prospective clinical trial is warranted.

description: Anknüpfend an die Anmerkungen zur Gegenstandskonstitution von Marcus Rauterberg und Gerold Scholz „Die Welt im Bild“ (Rauterberg & Scholz 2003), möchte ich im Folgenden erörtern, was es heißt, Gegenstände des Sachunterrichts weder realistisch noch nominalistisch (dementsprechend auch nicht idealistisch bzw. sensualistisch oder positivistisch) als gegeben vorauszusetzen, vielmehr (erkenntnis-)kritisch die Bildung dieser Vorstellungen zu Gegenständen der Erfahrung als das entscheidende bildungstheoretische Problem zu sehen. Damit soll die kantisch-neuzeitliche Sichtweise auch als Bedingung einer Rahmentheorie für die Genese und Etablierung von Unterrichtsgegenständen thematisiert werden.Diese konzeptuelle Arbeit scheint mir nicht nur produktiv, sondern auch notwendig, weil das Bewusstsein für die genetische Struktur der Gegenstandskonstitution die Geschichtlichkeit der schulpädagogischen und didaktischen Forschung in den Vordergrund stellt. Sie trägt also sowohl zu einer exakten Formulierung des Forschungsfeldes als auch zur Eröffnung von Alternativen bei. Dem gegenüber setzt der postulierte Wechsel der Präferenz innerhalb der Bildungsforschung zu einer empirisch ausgerichteten Wirksamkeitsforschung eine perfekte Gegenstandskonstitution voraus, da nur in einem geschlossenen System die Variablen Input und Output soweit kontrollierbar sind, dass Einflussfaktoren und Kriterien der Effizienzsteigerung untersucht werden können. Dies würde aber entweder das kulturelle Feld aus der Forschung ausklammern oder die Kulturgenese zum Stillstand bringen, insofern nur noch Bildungsprozesse ermöglicht werden, welche den Status quo bestärken, jedoch keine projektiven Entwürfe entstehen, welche auf gesellschaftlich-kulturelle Entwicklungen mit neuen handlungsleitenden Ideen und Vorstellungen antworten.

Group 4 ureate complexes : synthesis, reactivity, and catalytic carbon-element bond formation
Creators: name: Leitch, David Charles
Publisher: name: University of British Columbia
Year: 2011

description: The synthesis, characterization, and reactivity patterns of three new classes of ureate- supported group 4 compounds are described, constituting the first comprehensive examination of the use of these electron-rich ligands. Four ureates with varying steric and electronic properties are included here: two mono(ureate)s and two tethered bis(ureate)s. Synthesis of dichlorobis(ureato) titanium and zirconium derivatives can be accomplished using several methods, with direct protonolysis between the urea proligand and M(NMe₂)₂Cl₂ precursors giving the highest yield. Solid-state and solution-phase characterization indicates the distal dialkylamino substituent on the ureate donates electron density into the chelate. While use of non-tethered ligands results in zirconium complexes that are fluxional in solution, tethered bis(ureato) ligands support well-defined species. These complexes retain neutral ligands, which are not easily removed. Ureate- supported zirconium dialkyl complexes can also be prepared by protonolysis between a urea and tetraalkyl zirconium compounds. The electron-rich nature of the ureate ligands allows the isolation of coordinatively unsaturated dialkyl complexes. Ureate-supported bis(amido) compounds of titanium and zirconium have been developed as precatalysts for hydroamination. A comprehensive structural comparison between related amidate and ureate complexes reveals that the ureate ligands bind tighter to their metal centers than amidates. As a consequence of this, and the electron-rich nature of the ureate ligands, amidate precatalysts are generally more effective for intramolecular hydroamination of alkenes than ureate precatalysts. In contrast, precatalysts with tethered ureate ligands are more effective than analogous amidates. The most active system identified through catalytic screening exhibits broad substrate scope and functional group tolerance. Most importantly, this is the first group 4 system that is highly effective with both primary and secondary amines. Mechanistic investigations have revealed that catalysis with the tethered bis(ureate) precatalyst does not proceed through an imido-mediated [2+2] cycloaddition-type mechanism. Instead, the key bond forming step is proposed to occur through concerted insertion of the alkene into a Zr–N bond and protonation of the terminal alkene carbon by a coordinated amine ligand. This proposal is supported by stoichiometric and kinetic investigations, which indicate that a proton-source accelerates alkene insertion, and a primary kinetic isotope effect when using an N-deuterated aminoalkene.
Kadanoff-Baym approach to double-excitations in finite systems

description: We benchmark many-body perturbation theory by studying neutral, as well as non-neutral, excitations of finite lattice systems. The neutral excitation spectra are obtained by time-propagating the Kadanoff-Baym equations in the Hartree-Fock and second Born approximations. Our method is equivalent to solving the Bethe-Salpeter equation with a high-level kernel while respecting self-consistently, which guarantees the fulfillment of a frequency sum rule. As a result, we find that a time-local method, such as Hartree-Fock, can give incomplete spectra, while already the second Born, which is the simplest time-nonlocal approximation, reproduces well most of the additional excitations, which are characterized as double-excitations.

description: High-resolution X-ray spectra of O-type stars revealed less wind absorption than expected from smooth winds with conventional mass-loss rates. Various solutions have been proposed, including porous winds, optically thick clumps or an overall reduction of the mass-loss rates. The latter has a strong impact on the evolution of the star. Our final goal is to analyse high resolution X-ray spectra of O-type stars with a multi temperature plasma model in order to determine crucial wind parameters such as the mass loss rate, the CNO abundances and the X-ray temperature plasma distribution in the wind. In this context we are developing a modelling tool to calculate synthetic X-ray spectra. We present, here, the main ingredients and physics necessary for a such work. Our code uses the AtomDB emissivities to compute the intrinsic emissivity of the hot plasma as well as the CMFGEN model atmosphere code to evaluate the opacity of the cool wind. Following the comparison between two formalisms of stellar wind fragmentation, we introduce, for the first time in X-rays, the effects of a tenuous inter-clump medium. We then explore the quantitative impact of different model parameters on the X-ray spectra such as the position in the wind of the X-ray emitting plasma. For the first time, we show that the two formalisms of stellar wind fragmentation yield different results, although the differences for individual lines are small and can probably not be tested with the current generation of X-ray telescopes. As an illustration of our method, we compare various synthetic line profiles to the observed O VIII λ 18.97Å line in the spectrum of ζ Puppis. We illustrate how different combinations of parameters can actually lead to the same morphology of a single line, underlining the need to analyse the whole spectrum in a consistent way when attempting to constrain the parameters of the wind.

description: Die Arbeit beschäftigt sich mit Bildern von Männlichkeit und der Notwendigkeit für die Entwicklung von Jungen, ein „verändertes“ Männlichkeitsbild im Sachunterricht zu integrieren. Dass am derzeitigen Frauenbild ebenfalls weiter gearbeitet werden muss, soll nicht angezweifelt werden. Der Aufbau der Arbeit gliedert sich in drei große Abschnitte. Im ersten Kapitel sollen Grundlagen geschaffen und geklärt werden, auf denen eine Analyse der Schulbücher und die darauf folgende Entwicklung von Kriterien aufbauen kann. Folgende Fragen sollen aufgegriffen werden:• Was ist unter Männlichkeit zu verstehen?• Was zeichnet die männliche Sozialisation aus?• Warum ist Veränderung von Männlichkeitsbildern notwendig, welche Ziele sollen damit erreicht werden?• In welchem Verhältnis stehen Sachunterricht und Männlichkeit zueinander?

title: A re-examination of Hegel's Science of Logic
Creators: name: Johnson, Paul Owen
Publisher: name: University of Kent
Year: 2023

description: I contend that the approach of previous scholars to Hegel's Science of Logic is quite inappropriate. They presuppose that it contains an attempt at the logical deduction of the pure categories of thought, and go on to ask whether this attempt is successful or not. I argue that we ought not to make this presupposition, but ought rather to look more closely at what Hegel actually says and does in the text; this leads me to make a complete re-examination of Hegel's Logic, in which I try to relate the various points I believe Hegel to be making to substantive issues, at the same time comparing and contrasting Hegel's viewpoint to that of other scientists and philosophers, both ancient and modern. Finally, I conclude that Hegel's Logic is not a mere logical deduction of categories, but a critique of concepts productive of a logical hierarchy at the top of which is the concept of philosophical method itself. This critique, then, far from being something we can either take or leave as a whole, is something which itself needs to be looked at critically.

description: Im Januar 2005 hat widerstreit-sachunterricht per Mailverteiler an die in der GDSU organisierten FachdidaktikerInnen sowie an Studierende und Lehrkräfte die Frage nach der Bedeutung einer 5 für den Sachunterricht im Zeugnis verschickt. Die Antworten sind inhaltlich durchaus heterogen – die Gruppe der Antwortenden ebenfalls. Die größte Anzahl von Antworten stammt von Studierenden, in geringerer Anzahl von Kindern, Lehrkräften, wozu wir auch AusbilderInnen der 2. Phase zählen, und HochschullehrerInnen.Wir wollen in diesem Beitrag versuchen, die Antworten zu differenzieren: Zum einen hinsichtlich der Tätigkeitsbereiche der Antwortenden und zum anderen hinsichtlich der Dimensionen, die zur Beantwortung herangezogen werden. Unser primäres Interesse gilt dabei den Antworten der Kinder/SchülerInnen, die wir in einem zweiten Schritt den Antworten der LehrerInnen gegenüber stellen. Für die nähere Betrachtung haben wir die Antworten der SchülerInnen ausgewählt, da sie als Betroffene – und folgt man der schulischen Logik der Notengebung – auch als VerursacherInnen der 5en u.E. bisher kaum zu ihren Deutungen dieser und anderer Noten befragt wurden.

description: We construct a holographic p-wave superconductor model in the background of quintessence AdS black hole with an SU(2) Yang-Mills gauge field and then probe the effects of quintessence on the holographic p-wave superconductor. We investigate the relation between the critical temperature and the state parameter of quintessence, and present the numerical results for electric conductivity. It is shown that the condensation of the vector field becomes harder as the absolute value of the state parameter increases. Unlike the scalar condensate in the s-wave model, the condensation of the vector field in p-wave model can occur in the total value range of the state parameter $w_q$ of quintessence. These results could help us know more about holographic superconductor and dark energy.

Modified gravity approach based on a preferred time foliation

description: We propose, in a heuristic way, a relativistic modified gravity model as an alternative to particle dark matter at galactic scales. The model is based on a postulated preferred time foliation described by a dynamical scalar field called the "Khronon". In coordinates adapted to the foliation it appears as a modification of general relativity violating local Lorentz invariance in a regime of weak gravitational fields. The model is a particular case of non-canonical Einstein-aether theory, but in which the aether vector field is hypersurface orthogonal. We show that this model recovers the phenomenology of the modified Newtonian dynamics (MOND) in the non-relativistic limit, and predicts the same gravitational lensing as general relativity but with a modified Poisson-type potential.
