Positive development in early adolescence : the importance of supportive adults and social competencies for well-being and academic success
Creators: name: Oberle, Eva
Publisher: name: University of British Columbia
Year: 2013

description: Social and emotional well-being and academic achievement are key indicators for positive development and resilience in early adolescence. Central assets fostering positive development include contextual assets (e.g., supportive relationships) and personal assets (e.g., social and emotional competencies). Three studies were conducted to explore the relative importance of positive relationships for social and emotional well-being and academic achievement during early adolescence, and whether social and emotional competencies predict academic achievement longitudinally. Study 1 was a population-based cross-sectional study investigating family, school, and neighbourhood support in relation to social and emotional well-being and academic achievement in a socioeconomically (SES) diverse sample of 3,026 4th graders. All contextual assets positively predicted students’ well-being in a regression analysis. A significant interaction between SES and school support indicated that school support had a protective function for low SES students; a significant interaction between SES and family support indicated that family support was more important than SES in predicting students’ well-being. Furthermore, SES and family support were positive predictors of both reading and math achievement. Study 2 investigated the relative importance of personal (optimism) and contextual (positive peer relationships and home, school, and neighbourhood support) assets for life satisfaction in a cross-sectional sample of 1,402 4th to 7th graders. Multilevel modeling analyses suggested that optimism and the four contextual variables significantly and positively predicted life satisfaction. School and neighbourhood support aggregated at the school level significantly predicted life satisfaction beyond their significant role at the individual, non-aggregated level. Study 3 was a short-term longitudinal study examining social and emotional competencies in 461 6th grade students as predictors of academic achievement in grade 7. Regression analyses revealed that social responsibility goals positively predicted reading achievement for boys only. Moreover, teacher-rated social-emotional skills positively predicted reading achievement for both boys and girls. With regard to math, only teacher-rated social-emotional skills predicted academic achievement. The importance of investigating social and emotional well-being and competence in conjunction with personal and contextual assets in early adolescence is discussed. Theoretical and practical implications of the findings along with the strengths and limitations of the three studies are put forth.

description: Noch immer sind Frauen in Spitzengremien der Privatwirtschaft deutlich unterrepräsentiert. Um dem entgegenzuwirken, haben in den vergangenen Jahren mehrere europäische Länder gesetzliche Geschlechterquoten eingeführt. Andere bauen – zumindest bisher – auf bloße Empfehlungen zu Gender Diversity in den nationalen Leitlinien zur Unternehmensführung. Wie ein deskriptiver Vergleich der Entwicklung des Frauenanteils in den höchsten Kontroll- beziehungsweise Entscheidungsgremien der größten börsennotierten Unternehmen in europäischen Ländern zeigt, sind gesetzlich verbindliche Geschlechterquoten das deutlich wirksamere Mittel. Das gilt umso mehr, wenn den Unternehmen bei Nichteinhaltung der gesetzlichen Geschlechterquote harte Sanktionen wie Strafzahlungen oder sogar die Auflösung des Unternehmens drohen. Dies legt nahe, dass von freiwilligen Selbstverpflichtungen oder gesetzlichen Regelungen ohne harte Sanktionen keine bedeutenden Steigerungen des Frauenanteils in Spitzenpositionen zu erwarten sind. Dies sollte auch mit Blick auf andere Bereiche, für die derzeit Quoten diskutiert werden, etwa Politik, Wissenschaft oder Medien, beachtet werden.

description: Die Abkühlung der Weltkonjunktur und die Unsicherheiten durch den Brexit haben der exportorientierten deutschen Wirtschaft zugesetzt. Sie dürfte in diesem Jahr nur um 0,5 Prozent wachsen. Dass die deutsche Wirtschaft aber nicht in eine ernsthafte Krise rutschen dürfte, ist den kräftigen finanzpolitischen Impulsen und einer günstigen Arbeitsmarktentwicklung zu verdanken. Dadurch bleibt der private Konsum eine Stütze der Wirtschaft; hinzu kommt eine moderate Inflation, die auch in den kommenden beiden Jahren die Kaufkraft kaum dämpft. Diese Faktoren werden zusammen mit einer wieder stärkeren Auslandsnachfrage dafür sorgen, dass sich im kommenden und übernächsten Jahr die deutsche Wirtschaft wieder etwas erholt. Sie dürfte pro Jahr um 1,4 Prozent wachsen – vorausgesetzt, die erheblichen politischen Risiken materialisieren sich nicht. So würde ein harter Brexit das Wachstum in Deutschland allein im kommenden Jahr um 0,4 Prozentpunkte belasten.

description: We consider a spin-orbit coupled configuration of spin-1/2 interacting bosons with equal Rashba and Dresselhaus couplings. The phase diagram of the system is discussed with special emphasis to the role of the interaction treated in the mean-field approximation. For a critical value of the density and of the Raman coupling we predict the occurrence of a characteristic tri-critical point separating the spin mixed, the phase separated and the single minimum states of the Bose gas. The corresponding quantum phases are investigated analyzing the momentum distribution, the longitudinal and transverse spin-polarization and the emergence of density fringes. The effect of harmonic trapping as well as the role of the breaking of spin symmetry in the interaction Hamiltonian are also discussed.

description: Die hauptsächlich von den USA ausgehenden Handelskonflikte und die Unsicherheit über den Austritt des Vereinigten Königreichs aus der Europäischen Union belasten die weltweite Konjunktur. Der globale Handel und die Investitionstätigkeit, und somit vielerorts auch die Industrieproduktion, sind die Leidtragenden, während der Konsum in vielen Ländern die Wirtschaft noch stützt. Das DIW Berlin erwartet für dieses Jahr ein Wachstum von 3,7 Prozent des weltweiten Bruttoinlandsprodukts und etwas weniger für die beiden Folgejahre. Die Risiken für die Weltkonjunktur sind hoch. Die Handelskonflikte könnten noch weiter eskalieren und sich auf die Europäische Union ausdehnen, zudem steht ein ungeordneter Brexit im Raum.

description: Most classification algorithms used in high energy physics fall under the category of supervised machine learning. Such methods require a training set containing both signal and background events and are prone to classification errors should this training data be systematically inaccurate for example due to the assumed MC model. To complement such model-dependent searches, we propose an algorithm based on semi-supervised anomaly detection techniques, which does not require a MC training sample for the signal data. We first model the background using a multivariate Gaussian mixture model. We then search for deviations from this model by fitting to the observations a mixture of the background model and a number of additional Gaussians. This allows us to perform pattern recognition of any anomalous excess over the background. We show by a comparison to neural network classifiers that such an approach is a lot more robust against misspecification of the signal MC than supervised classification. In cases where there is an unexpected signal, a neural network might fail to correctly identify it, while anomaly detection does not suffer from such a limitation. On the other hand, when there are no systematic errors in the training data, both methods perform comparably.

description: Certain AdS black holes are "fragile", in the sense that, if they are deformed excessively, they become unstable to a fundamental non-perturbative stringy effect analogous to Schwinger pair-production [of branes]. Near-extremal topologically spherical AdS-Kerr black holes, which are natural candidates for string-theoretic models of the very rapidly rotating black holes that have actually been observed to exist, do represent a very drastic deformation of the AdS-Schwarzschild geometry. One therefore has strong reason to fear that these objects might be "fragile", which in turn could mean that asymptotically flat rapidly rotating black holes might be fragile in string theory. Here we show that this does not happen: despite the severe deformation implied by near-extremal angular momenta, brane pair production around topologically spherical AdS-Kerr black holes is always suppressed.

Ruthenium(II) complexes bearing polypyridyl ligands with amide bound thienyl groups for photochemical energy conversion
Creators: name: Majewski, Marek B.
Publisher: name: University of British Columbia

description: Mimicking natural photosynthesis requires long charge recombination lifetimes, spatial charge separation, and sufficient excited state energy to catalyze processes such as water splitting. Complexes bearing laminate acceptor ligands and ancillary diimine ligands with electron rich donor moieties are suitable candidates as reaction centers for photoinduced charge separation in artificial photosynthesis. In this work, new diimine ligands with thiophene oligomers appended via amide linkages are incorporated into metal polypyridyl complexes. Homoleptic Ru²⁺ complexes bearing 1,10-phenanthroline ligands with amide bound bithiophene units exhibit excited state behavior deviating significantly from that observed in [Ru(phen)₃][PF₆]₂ (30). The bithiophene unit fuels a long-lived excited state (τ ≈ 7 μs) in [Ru(phen-btL)₃][PF₆]₂ (32) through an energy reservoir effect, where ³LC and ³MLCT states are equilibrating in the excited state. A third ³ILCT state is found to equilibrate with the aforementioned states giving a rare three-state equilibrium where the third state is a charge separated state storing ΔG° ≥ 1.9 eV of energy. In order to introduce an aspect of vectorial charge separation into donor-chromophore-acceptor triads, 1,10-phenanthroline ligands bearing bithiophene moieties are introduced as donor ligands into Ru²⁺-based triads with laminate polypyridyl acceptor ligands; dipyrido[3,2-a:2',3'-c]phenazine (dppz), tetrapyrido[3,2-a:2',3'-c:3'',2''-h:2''',3'''-j]phenazine (tpphz), and 9,11,20,22-tetraazatetrapyrido[3,2-a:2',3'-c:3'',2''-l:2''',3''']-pentacene (tatpp). Triads incorporating bithiophene amide diimine ligands and laminate acceptor ligands (50-52) have long-lived charge separated excited states (τes = 2.2 – 7.0 μs), where an electron is localized on the central portion of the acceptor ligand. Charge separated excited states in these triads transiently store an appreciable amount of energy (ΔG° ≈ 0.98 – 1.41 eV)

description: We construct a compact phase space for flat FLRW spacetimes with standard matter described by a perfect fluid with a barotropic equation of state for general f(R) theories of gravity, subject to certain conditions on the function f. We then use this framework to study the behaviour of the phase space of Universes with a non-negative Ricci scalar in R + αR^n gravity. We find a number of interesting cosmological evolutions which include the possibility of an initial unstable power-law inflationary point, followed by a curvature fluid dominated phase mimicking standard radiation, then passing through a standard matter (CDM) era and ultimately evolving asymptotically towards a de-Sitter-like late-time accelerated phase.

description: Das Beheizen von Wohnräumen macht fast ein Fünftel des Endenergieverbrauchs in Deutschland aus. Der vorliegende Bericht wertet einen umfangreichen Datenbestand von Heizenergieabrechnungen von Zwei- und Mehrfamilienhäusern in Deutschland aus – diese repräsentieren mehr als zwei Drittel des gesamten Gebäudebestands. Die energetische Sanierungsrate des Gebäudebestands verharrt seit der Jahrtausendwende auf einem niedrigen Stand, während der Heizwärmebedarf von privaten Haushalten je Quadratmeter seit 2015 einen Aufwärtstrend verzeichnet. Mit Blick auf die deutschen Klimaziele für 2050 im Gebäudebereich ist dies eine alarmierende Entwicklung. Es bedarf daher zusätzlicher Politikmaßnahmen, um den Energiebedarf im Gebäudebereich deutlich zu senken. Dazu zählen beispielsweise steuerliche Anreize für tiefgreifende Modernisierungen sowie Maßnahmen, die auf das Verhalten privater Haushalte zielen.

description: Convolutional neural networks (CNNs) have taken the spotlight in a variety of machine learning applications. To reach the desired performance, CNNs have become increasingly deeper and larger which goes along with a tremendous amount of power and storage requirements. Such increases in computational demands and memory make deep learning prohibitive for resource-constrained hardware platforms such as mobile devices. In order to address this problem, we provide a general framework which renders efficient CNN representations that solve given classification tasks to specified quality levels. More precisely, the framework yields sparse and ternary neural networks, i.e. networks with many parameters set to zero and the non-zero parameters quantized from 32 bit to 2 bit. Ternary networks are not only efficient in terms of storage but also in terms of computational complexity. By explicitly boosting sparsity we reach further efficiency gains. The proposed framework follows a two-step paradigm. First, a baseline model is extended by compound model scaling until a specified target accuracy is reached. Secondly, our Entropy-Constrained Trained Ternarization (EC2T) algorithm is applied which simultaneously quantizes and sparsifies the scaled model. Here, a \(\lambda\)-operator balances the entropy constraint and thus the compression gain of the resulting network. We validated the effectiveness of EC2T in a variety of experiments. This includes CIFAR-10, CIFAR-100 and ImageNet classification tasks and the compression of renowned architectures (i.e., ResNets and EfficientNet) as well as our own compound-scaled models. We show the advantages of EC2T compared to the standard in ternary quantization, Trained Ternary Quantization (TTQ), and set new benchmarks in this research area. For instance, EC2T compresses ResNet-20 by more than 24x and reduces the number of arithmetical operations by more than 12x while causing a minimal accuracy degradation of 0.9%.

description: We present a study of "nodal semimetal" phases, in which non-degenerate conduction and valence bands touch at points (the "Weyl semimetal") or lines (the "line node semimetal") in three-dimensional momentum space. We discuss a general approach to such states by perturbation of the critical point between a normal insulator (NI) and a topological insulator (TI), breaking either time reversal (TR) or inversion symmetry. We give an explicit model realization of both types of states in a NI--TI superlattice structure with broken TR symmetry. Both the Weyl and the line-node semimetals are characterized by topologically-protected surface states, although in the line-node case some additional symmetries must be imposed to retain this topological protection. The edge states have the form of "Fermi arcs" in the case of the Weyl semimetal: these are chiral gapless edge states, which exist in a finite region in momentum space, determined by the momentum-space separation of the bulk Weyl nodes. The chiral character of the edge states leads to a finite Hall conductivity. In contrast, the edge states of the line-node semimetal are "flat bands": these states are approximately dispersionless in a subset of the two-dimensional edge Brillouin zone, given by the projection of the line node onto the plane of the edge. We discuss unusual transport properties of the nodal semimetals, and in particular point out quantum critical-like scaling of the DC and optical conductivity of the Weyl semimetal, and similarities to the conductivity of graphene in the line node case.

description: We develop a general technique to analyse the quantum effects of acceleration on realistic spatially-localised electromagnetic field states entangled in the polarization degree of freedom. We show that for this setting, quantum entanglement may build up as the acceleration increases, providing a clear signature of the quantum effects of relativistic acceleration.

description: Seit Einführung des Elterngeldes im Jahr 2007 gehen – ausgehend von einem extrem niedrigen Niveau – immer mehr Väter in Elternzeit. Im Vergleich zu Müttern ist das jedoch nach wie vor deutlich seltener der Fall und wenn, dann ist der Umfang der Elternzeit bei Vätern relativ kurz. Seit im Jahr 2015 das Elterngeld Plus eingeführt wurde, kombinieren zwar mehr Mütter und auch Väter die Elternzeit mit einer Teilzeiterwerbstätigkeit – der absolute Anteil von Vätern, die Elternzeit nehmen, ist zumindest kurzfristig aber nicht weiter gestiegen. Als wichtigstes Motiv gegen den Bezug von Elterngeld werden von Vätern finanzielle Gründe angegeben. Auch die Sorge vor negativen beruflichen Konsequenzen wird häufig genannt. Diese beiden Punkte könnten von der Politik zum einen durch ein Anheben der Lohnersatzrate im unteren Einkommensbereich und zum anderen durch bessere Informationen über die zu erwartenden Auswirkungen von Elternzeit auf die zukünftigen Löhne und beruflichen Karrieren von Müttern und Vätern adressiert werden

Exploring the genetic interactome of a Saccharomyces cerevisiae separase mutant
Creators: name: Ho, Krystina
Publisher: name: University of British Columbia
Year: 2015

description: The budding yeast Saccharomyces cerevisiae is used as a model organism for understanding cellular dynamics such as cell cycle regulation. Separase endopeptidases are essential to these events, being responsible for cleavage of cohesin – the molecular glue holding sister chromatids together. To examine the function of separases in a systematic fashion, a temperature sensitive mutant of the yeast homologue, Esp1, was subjected to a high-throughput technique known as synthetic genetic array to identify genetic interactions. Examination of the list of alleles confirmed to cause a synthetic lethal or synthetic dosage lethal phenotype in the query esp1-1 mutant (“hits”) established the legitimacy of these screens, as many related to known Esp1 functions. Surprisingly, categorization of these hits by biological process revealed an enrichment for genes involved in RNA metabolic processes. Concurrent affinity immunoprecipitation of separase followed by mass spectrometry further showed a physical interaction between Esp1 and the integrase portion of Ty1 retrotransposons. Evidence that this interaction was indicative of a role for separase in retrotransposition was attained when the esp1-1 mutant was found to have transposition defects. Similar defects were also present in mutants of both the cohesin loader, SCC2, and the structural maintenance of chromosome, SMC3, genes. Interestingly, cohesin loads at loci transcribed by RNA polymerase III, while hotspots of Ty1 integration are upstream of the same sites. I propose that separase acts as a bridge to aid in targeting the Ty1 pre-integration complex to these hotspots. The aforementioned categorization of esp1-1 genetic interactors also indicated that separase may somehow be involved in mRNA biogenesis. As esp1-1 mutants have intact translational machinery, my data suggests that separase functions either directly in transcription or, more likely, post-transcriptionally. In all, screening for esp1-1 genetic interactions has revealed several new avenues for separase studies.
Robust Parametric Classification and Variable Selection by a Minimum Distance Criterion

description: We investigate a robust penalized logistic regression algorithm based on a minimum distance criterion. Influential outliers are often associated with the explosion of parameter vector estimates, but in the context of standard logistic regression, the bias due to outliers always causes the parameter vector to implode, that is shrink towards the zero vector. Thus, using LASSO-like penalties to perform variable selection in the presence of outliers can result in missed detections of relevant covariates. We show that by choosing a minimum distance criterion together with an Elastic Net penalty, we can simultaneously find a parsimonious model and avoid estimation implosion even in the presence of many outliers in the important small $n$ large $p$ situation. Implementation using an MM algorithm is described and performance evaluated.

Single-Scale Natural SUSY

description: We consider the prospects for natural SUSY models consistent with current data. Recent constraints make the standard paradigm unnatural so we consider what could be a minimal extension consistent with what we now know. The most promising such scenarios extend the MSSM with new tree-level Higgs interactions that can lift its mass to at least 125 GeV and also allow for flavor-dependent soft terms so that the third generation squarks are lighter than current bounds on the first and second generation squarks. We argue that a common feature of almost all such models is the need for a new scale near 10 TeV, such as a scale of Higgsing or confinement of a new gauge group. We consider the question whether such a model can naturally derive from a single mass scale associated with supersymmetry breaking. Most such models simply postulate new scales, leaving their proximity to the scale of MSSM soft terms a mystery. This coincidence problem may be thought of as a mild tuning, analogous to the usual mu problem. We find that a single mass scale origin is challenging, but suggest that a more natural origin for such a new dynamical scale is the gravitino mass, m_{3/2}, in theories where the MSSM soft terms are a loop factor below m_{3/2}. As an example, we build a variant of the NMSSM where the singlet S is composite, and the strong dynamics leading to compositeness is triggered by masses of order m_{3/2} for some fields. Our focus is the Higgs sector, but our model is compatible with a light stop (with the other generation squarks heavy, or with R-parity violation or another mechanism to hide them from current searches). All the interesting low-energy mass scales, including linear terms for S playing a key role in EWSB, arise dynamically from the single scale m_{3/2}. However, numerical coefficients from RG effects and wavefunction factors in an extra dimension complicate the otherwise simple story.

A Global View on The Search for de-Sitter Vacua in (type IIA) String Theory

description: The search for classically stable Type IIA de-Sitter vacua typically starts with an ansatz that gives Anti-de-Sitter supersymmetric vacua and then raises the cosmological constant by modifying the compactification. As one raises the cosmological constant, the couplings typically destabilize the classically stable vacuum, so the probability that this approach will lead to a classically stable de-Sitter vacuum is Gaussianly suppressed. This suggests that classically stable de-Sitter vacua in string theory (at least in the Type IIA region), especially those with relatively high cosmological constants, are very rare. The probability that a typical de-Sitter extremum is classically stable (i.e., tachyon-free) is argued to be Gaussianly suppressed as a function of the number of moduli.
