description: Biodiversity loss in urban landscapes is a global challenge. Climate change is a major driving force behind biodiversity loss worldwide. Using Wellington, New Zealand as a research site, the aim of this research is to show how the most suitable patches of vegetation in urban landscapes can be identified, ranked, and prioritised as potential urban wildlife sanctuaries. This is in order to protect vulnerable indigenous fauna from some of the indirect impacts of climate change such as increased predator pressures and the spread of diseases among urban fauna caused by rising temperatures. A GIS-based multi-criteria analysis of spatial composition and configuration of patches of vegetation was undertaken with reference to eight factors affecting the quality of habitat patches and accordingly fauna behaviours in urban landscapes. Results show that Zealandia, the Wellington Botanic Garden, the Town Belt, and Otari-Wilton's Bush are respectively the most important urban sites for establishing pest-free urban wildlife sanctuaries in the study area. This research reveals that patch size should not be considered as the single most important factor for the site selection of urban wildlife sanctuaries because the collective importance of other factors may outweigh the significance of patch size as a single criterion. Lessons learned in the course of this research can be applied in similar cases in New Zealand or internationally in order to facilitate the process of site selection for the establishment of urban wildlife sanctuaries in highly fragmented urban landscapes suffering from rising temperatures and other climatic changes.

description: Eltern haben im Zuge der ersten coronabedingten Kita- und Schulschließungen einen Großteil der Bildungs- und Betreuungsarbeit übernommen. Vielfach wurde in der Öffentlichkeit diskutiert, inwiefern die Corona-Pandemie die Aufteilung von Sorge- und Erwerbsarbeit zwischen Müttern und Vätern verändert hat. Eine Auswertung neuer pairfam-Daten zeigt ein differenziertes Bild: Einerseits hat sich der Anteil der Paare, die sich Kinderbetreuung und Hausarbeit egalitär aufteilen, nicht signifikant verändert. Andererseits ist bei Paaren, bei denen die Frauen bereits vor der Pandemie den überwiegenden Teil der Sorgearbeit übernommen haben, das Ungleichgewicht in der Pandemie noch größer geworden. Im Frühjahr und Sommer 2020 haben Frauen in rund 16 Prozent und damit im Vorjahresvergleich in etwa doppelt so vielen Familien (fast) vollständig die Kinderbetreuung übernommen. Wenn Mütter im Homeoffice arbeiten, erledigen sie auch mehr Sorgearbeit, während dies bei Vätern nicht der Fall ist. Die Aufteilung der Sorgearbeit wird dabei von Müttern und Vätern sehr unterschiedlich wahrgenommen. Die Politik sollte aus einer gleichstellungspolitischen Perspektive bei neuen familienbezogenen Leistungen die ungleiche Verteilung der Sorgearbeit stärker in den Blick nehmen. Helfen könnten beispielsweise finanzielle Anreize für eine gleichmäßigere Aufteilung der Elternzeit.

description: The present article discusses magnetic confinement of the Dirac excitations in graphene in presence of inhomogeneous magnetic fields. In the first case a magnetic field directed along the z axis whose magnitude is proportional to $1/r$ is chosen. In the next case we choose a more realistic magnetic field which does not blow up at the origin and gradually fades away from the origin. The magnetic fields chosen do not have any finite/infinite discontinuity for finite values of the radial coordinate. The novelty of the two magnetic fields is related to the equations which are used to find the excited spectra of the excitations. It turns out that the bound state solutions of the two-dimensional hydrogen atom problem are related to the spectra of graphene excitations in presence of the $1/r$ (inverse-radial) magnetic field. For the other magnetic field profile one can use the knowledge of the bound state spectrum of a two-dimensional cut-off Coulomb potential to dictate the excitation spectra of the states of graphene. The spectrum of the graphene excitations in presence of the inverse-radial magnetic field can be exactly solved while the other case cannot be. In the later case we give the localized solutions of the zero-energy states in graphene.

description: We present deep wide-field photometry of three recently discovered faint Milky Way satellites: Leo V, Pisces II, and Canes Venatici II. Our main goals are to study the structure and star formation history of these dwarfs; we also search for signs of tidal disturbance. The three satellites have similar half-light radii ($\sim 60-90$ pc) but a wide range of ellipticities. Both Leo V and CVn II show hints of stream-like overdensities at large radii. An analysis of the satellite color-magnitude diagrams shows that all three objects are old ($>$ 10 Gyr) and metal-poor ([Fe/H] $\sim -2$), though neither the models nor the data have sufficient precision to assess when the satellites formed with respect to cosmic reionization. The lack of an observed younger stellar population ($\la 10$ Gyr) possibly sets them apart from the other satellites at Galactocentric distances $\ga 150$ kpc. We present a new compilation of structural data for all Milky Way satellite galaxies and use it to compare the properties of classical dwarfs to the ultra-faints. The ellipticity distribution of the two groups is consistent at the $\sim$2-$σ$ level. However, the faintest satellites tend to be more aligned toward the Galactic center, and those satellites with the highest ellipticity ($\ga 0.4$) have orientations ($Δθ_{GC}$) in the range $20^{\circ} \lesssim Δθ_{GC} \lesssim 40^{\circ}$. This latter observation is in rough agreement with predictions from simulations of dwarf galaxies that have lost a significant fraction of their dark matter halos and are being tidally stripped.

description: Little Penguin (Eudyptula minor) is one of the most ecologically important seabirds in New Zealand and depends strongly on terrestrial ecosystems for nesting, moulting and breeding. Wellington, New Zealand, is one of the world's most important biodiversity hot spots for this species, mostly in confluence with human urban settlements. This species is currently suffering from the local impacts of climate change associated with urbanisation. Two suburbs of Wellington, New Zealand, that are used seasonally by Little Penguin as terrestrial habitat were selected as the study area to address two issues: (i) how local impacts of climate change may affect the population and habitat structure of species in urban coastal zones where land cover change occurs; and (ii) how landscape management practices may help to mitigate the impacts imposed by climate change on the species in such a context. Remote Sensing and Geographical Information Systems techniques were applied to quantify and measure the extent of the prehuman forests and current land cover classes in the study area to reveal the degree to which land cover has changed from predevelopment to the present time. The research shows that land cover change in the study area has been widespread and partly irreversible, particularly in areas covered by the class Built-up Area. Results reveal that there are still spatial opportunities to safeguard this vulnerable species against the ill effects of climate change through landscape management practices.

description: Vor einem Jahr trat in Berlin der Mietendeckel in Kraft, mit dem die seit Jahren stark steigenden Mieten für fünf Jahre eingefroren werden sollen. Der Mietendeckel sieht verbindliche Quadratmeterpreise vor, nur wenig differenziert und nur mit wenigen Ausnahmen. Mithilfe von Mietannoncen werden die Effekte dieser Maßnahmen auf den Berliner Wohnungsmarkt untersucht. Die in den Annoncen geforderten Mieten für die regulierten Wohnungen sind demnach in direkter Folge auf die rechtlich bindende Einführung am 23. Februar 2020 im Vergleich zu den unregulierten um sieben bis elf Prozent gefallen. Aber nur für ein Viertel dieser annoncierten Wohnungen werden in den Inseraten regelkonforme Mieten angegeben. Zudem ist die Zahl der inserierten Mietwohnungen deutlich zurückgegangen. Im Umland, beispielsweise in Potsdam, das dem Mietendeckel nicht unterliegt, sind gleichzeitig die Preise um rund zwölf Prozent gestiegen. Die langfristigen Auswirkungen des Mietendeckels sind zwar noch unbekannt, allerdings weisen erste Indizien sowie die umfangreiche empirische Literatur auf eher negative Effekte hin. Zielführender wäre es, mehr Anstrengungen in den Wohnungsbau zu stecken.

description: Holographic optical tweezers are used to construct a static bistable optical potential energy landscape where a Brownian particle experiences restoring forces from two nearby optical traps and undergoes thermally activated transitions between the two energy minima. Hydrodynamic coupling between two such systems results in their partial synchronisation. This is interpreted as an emergence of higher mobility pathways, along which it is easier to overcome barriers to structural rearrangement.

description: Der katastrophale Unfall im japanischen Kernkraftwerk Fukushima am 11. März 2011 brachte einmal mehr unerwartete Sicherheitsrisiken zutage und beschleunigte den Bedeutungsverlust von Kernkraft in der internationalen Energiewirtschaft. Ihr Anteil an der globalen Stromerzeugung fiel von vormals 17 Prozent (1996) über 13 Prozent (2011) auf circa zehn Prozent, der Anteil am Primärenergieverbrauch liegt sogar bei nur noch vier Prozent. Neben den seit 1945 regelmäßig auftretenden Großunfällen kommt es auch immer wieder zu erheblichen Ausfallzeiten von Kernkraftwerken im normalen Betrieb: Weltweit beträgt die Nutzung der verfügbaren Kraftwerkskapazität seit den 1970er Jahren lediglich 66 Prozent. Auch in Deutschland und den Nachbarländern gab es eine Vielzahl von Zwischenfällen. Zwar liegen die Ausfallzeiten der deutschen Kernkraftwerke unter dem internationalen Durchschnitt, dennoch sind sie hier ebenfalls erheblich, auch bei den jüngeren Anlagen. Die unzuverlässige Verfügbarkeit von Kernkraft ist in der energiewirtschaftlichen Analyse bisher weitgehend vernachlässigt – bisher sehen viele Energie- und Klimamodelle noch eine Bedeutung von Kernkraft auch in der Zukunft. Der Unfall in Fukushima beschleunigte den Atomausstieg in Deutschland, der entsprechend des 13. Gesetzes zur Änderung des Atomgesetzes (Juli 2011) bis Ende 2022 erfolgen soll.

description: We investigate the energy relaxation of hot carriers produced by photoexcitation of graphene through coupling to both intrinsic and remote (substrate) surface polar phonons using the Boltzmann equation approach. We find that the energy relaxation of hot photocarriers in graphene on commonly used polar substrates, under most conditions, is dominated by remote surface polar phonons. We also calculate key characteristics of the energy relaxation process, such as the transient cooling time and steady state carrier temperatures and photocarriers densities, which determine the thermoelectric and photovoltaic photoresponse, respectively. Substrate engineering can be a promising route to efficient optoelectronic devices driven by hot carrier dynamics.

Self-completeness and spontaneous dimensional reduction

description: A viable quantum theory of gravity is one of the biggest challenges facing physicists. We discuss the confluence of two highly expected features which might be instrumental in the quest of a finite and renormalizable quantum gravity -- spontaneous dimensional reduction and self-completeness. The former suggests the spacetime background at the Planck scale may be effectively two-dimensional, while the latter implies a condition of maximal compression of matter by the formation of an event horizon for Planckian scattering. We generalize such a result to an arbitrary number of dimensions, and show that gravity in higher than four dimensions remains self-complete, but in lower dimensions it is not. In such a way we established an "exclusive disjunction" or "exclusive or" (XOR) between the occurrence of self-completeness and dimensional reduction, with the goal of actually reducing the unknowns for the scenario of the physics at the Planck scale. Potential phenomenological implications of this result are considered by studying the case of a two-dimensional dilaton gravity model resulting from dimensional reduction of Einstein gravity.

The leftovers of planet formation : small body populations of our solar system and exoplanet systems
Creators: name: Lawler, Samantha
Publisher: name: University of British Columbia
Year: 2013

description: The small body populations within a planetary system give information about the planet formation and migration history of the system. In our Solar System, we study these bodies (asteroids, comets, and trans-Neptunian objects), by directly observing them in reflected light. In other solar systems, dust traces the position of the planetesimal belts that produce it, and is observed as an excess above the stellar flux in the infrared. The dust is visible and not the planetesimals because of the much greater cross-sectional surface area of a swarm of dust particles. In this thesis, both leftover large planetesimals in our Solar System and dust around other stars are investigated. Data from the Canada-France Ecliptic Plane Survey (CFEPS) are used to measure the absolute populations of trans Neptunian objects (TNOs) in mean-motion resonances with Neptune, as well as constrain the internal orbital element distributions. Detection biases play a critical role because phase relationships with Neptune make object discovery more likely at certain longitudes. The plutinos (objects in the 3:2 resonance) are given particular attention because the presence of the secular Kozai resonance within the mean-motion resonance causes different detection biases that need to be accounted for to properly debias surveys that include detections of plutinos. Because the TNOs that are trapped in mean-motion resonances with Neptune were likely emplaced there during planet migration late in the giant planet formation process, the structure within and relative populations of the resonances should be a diagnostic of the timescale and method of giant planet migration. Exoplanet systems that host several rocky planets are those that did not experience giant planet migration, and thus are likely to host planetesimal belts which should be detectable as debris disks. The Kepler Mission has detected a host of such systems, and we use data from the Wide-field Infrared Survey Explorer (WISE) Mission to search for debris disks around these stars. Though we tentatively detect more excesses toward these stars than would be expected, contamination from warm dust in the Milky Way Galaxy makes detection unreliable for these systems, and will have to await future infrared space telescopes.

description: We present an application of self-adaptive supervised learning classifiers derived from the Machine Learning paradigm, to the identification of candidate Globular Clusters in deep, wide-field, single band HST images. Several methods provided by the DAME (Data Mining & Exploration) web application, were tested and compared on the NGC1399 HST data described in Paolillo 2011. The best results were obtained using a Multi Layer Perceptron with Quasi Newton learning rule which achieved a classification accuracy of 98.3%, with a completeness of 97.8% and 1.6% of contamination. An extensive set of experiments revealed that the use of accurate structural parameters (effective radius, central surface brightness) does improve the final result, but only by 5%. It is also shown that the method is capable to retrieve also extreme sources (for instance, very extended objects) which are missed by more traditional approaches.

description: Measurements of gravitational waves from the inspiral of a stellar-mass compact object into a massive black hole are unique probes to test General Relativity (GR) and MBH properties, as well as the stellar distribution about these holes in galactic nuclei. Current data analysis techniques can provide us with parameter estimation with very narrow errors. However, an EMRI is not a two-body problem, since other stellar bodies orbiting nearby will influence the capture orbit. Any deviation from the isolated inspiral will induce a small, though observable deviation from the idealised waveform which could be misinterpreted as a failure of GR. Based on conservative analysis of mass segregation in a Milky Way like nucleus, we estimate that the possibility that another star has a semi-major axis comparable to that of the EMRI is non-negligible, although probably very small. This star introduces an observable perturbation in the orbit in the case in which we consider only loss of energy via gravitational radiation. When considering the two first-order non-dissipative post-Newtonian contributions (the periapsis shift of the orbit), the evolution of the orbital elements of the EMRI turns out to be chaotic in nature. The implications of this study are twofold. From the one side, the application to testing GR and measuring MBHs parameters with the detection of EMRIs in galactic nuclei with a millihertz mission will be even more challenging than believed. From the other side, this behaviour could in principle be used as a signature of mass segregation in galactic nuclei.

description: Seit rund zehn Jahren steigen in Berlin die Mietpreise von Wohnimmobilien stark an. Kurzzeitvermietungen über Vermittlungsplattformen wie Airbnb stehen im Verdacht diese Entwicklung weiter zu befeuern. Tatsächlich zeigen Schätzungen: Durch eine zusätzliche Airbnb-Unterkunft steigen im direkten Umfeld die Angebotsmieten um durchschnittlich 13 Cent je Quadratmeter. Dies ist vor allem auf dauerhafte Airbnb-Angebote zurückzuführen, die dem Wohnungsmarkt nicht mehr zur Verfügung stehen. Das im Jahr 2014 beschlossene Zweckentfremdungsverbot hat die kurzzeitige Untervermietung stark eingegrenzt. Infolgedessen ist das Angebot auf dem Mietwohnungsmarkt gestiegen und die Mieten sind dadurch etwas gesunken. Dabei kann die Ersparnis bei neu geschlossenen Mietverträgen abhängig vom Bezirk bis zu 38 Euro monatlich für eine 65 Quadratmeter große Wohnung betragen. Da jedoch nur ein geringer Anteil aller Berliner Wohnungen für kurzzeitige Vermietungen angeboten wird, dürfte das Zweckentfremdungsverbot die Wohnungsknappheit sowie den Mietpreisanstieg in der Hauptstadt nicht erheblich reduzieren.

description: The spectrum and eigenstates of any field quadrature operator restricted to a finite number $N$ of photons are studied, in terms of the Hermite polynomials. By (naturally) defining \textit{approximate} eigenstates, which represent highly localized wavefunctions with up to $N$ photons, one can arrive at an appropriate notion of limit for the spectrum of the quadrature as $N$ goes to infinity, in the sense that the limit coincides with the spectrum of the infinite-dimensional quadrature operator. In particular, this notion allows the spectra of truncated phase operators to tend to the complete unit circle, as one would expect. A regular structure for the zeros of the Christoffel-Darboux kernel is also shown.

description: We study three dimensional oceanic Lagrangian Coherent Structures (LCSs) in the Benguela region, as obtained from an output of the ROMS model. To do that we first compute Finite-Size Lyapunov exponent (FSLE) fields in the region volume, characterizing mesoscale stirring and mixing. Average FSLE values show a general decreasing trend with depth, but there is a local maximum at about 100 m depth. LCSs are extracted as ridges of the calculated FSLE fields. They present a "curtain-like" geometry in which the strongest attracting and repelling structures appear as quasivertical surfaces. LCSs around a particular cyclonic eddy, pinched off from the upwelling front are also calculated. The LCSs are confirmed to provide pathways and barriers to transport in and out of the eddy.

Befragungsdaten des Sozio-oekonomischen Panels (SOEP) und der Universität Bielefeld zeigen, dass LGBTQI*-Menschen drei-bis viermal so häufig von psychischen Erkrankungen betroffen sind. Auch potentiell stressbedingte körperliche Krankheiten wie Herzkrankheiten, Migräne, Asthma und chronische Rückenschmerzen kommen weitaus häufiger vor als in anderen Bevölkerungsgruppen. Wichtig für das gesundheitliche Wohlbefinden ist auch das soziale Umfeld. LGBTQI*-Menschen und darunter besonders Trans*-Menschen fühlen sich oft einsam. Hinsichtlich der in der Corona-Pandemie derzeit zunehmenden Einsamkeit vieler Menschen ist dies ein Grund zur Sorge. Die Befunde deuten auf eine massive Chancenungleichheit für ein gesundes Leben hin, der durch eine Ausweitung von queeren Beratungs- und Freizeitangeboten und der ausdrücklichen Benennung von LGBTQI*-Hasskriminalität im Strafgesetzbuch begegnet werden sollte.

description: Often experimentalists study colloidal suspensions that are nominally monodisperse. In reality these samples have a polydispersity of 4-10%. At the level of an individual particle, the consequences of this polydispersity are unknown as it is difficult to measure an individual particle size from microscopy. We propose a general method to estimate individual particle radii within a moderately concentrated colloidal suspension observed with confocal microscopy. We confirm the validity of our method by numerical simulations of four major systems: random close packing, colloidal gels, nominally monodisperse dense samples, and nominally binary dense samples. We then apply our method to experimental data, and demonstrate the utility of this method with results from four case studies. In the first, we demonstrate that we can recover the full particle size distribution {\it in situ}. In the second, we show that accounting for particle size leads to more accurate structural information in a random close packed sample. In the third, we show that crystal nucleation occurs in locally monodisperse regions. In the fourth, we show that particle mobility in a dense sample is correlated to the local volume fraction.

description: In this paper we present several finite families of congruences between cusp forms and Eisenstein series of higher weights at powers of prime ideals. We formulate a conjecture which describes properties of the prime ideals and their relation to the weights. We check the validity of the conjecture on several numerical examples.

description: Rund zehn Prozent aller Erwachsenen in Deutschland haben in den vergangenen 15 Jahren mindestens eine Erbschaft oder größere Schenkung erhalten. Die durchschnittliche Höhe dieser Erbschaften beläuft sich dabei real auf etwas mehr als 85 000 Euro pro Person, jene der Schenkungen auf 89 000 Euro, wie Daten des Sozio-oekonomischen Panels zeigen. Gegenüber dem Jahr 2001 haben sich die Erbschaften und Schenkungen im Durchschnitt real um etwa 20 Prozent erhöht. Intergenerationale Transfers sind ungleich verteilt: So fließt die Hälfte aller Erbschafts- und Schenkungssummen an die reichsten zehn Prozent der Begünstigten. Erbschaften und Schenkungen erhöhen damit die absolute Ungleichheit. Vor diesem Hintergrund sollte die Zehnjahresfrist – Freibeträge können alle zehn Jahre erneut in Anspruch genommen werden – aufgehoben werden, damit Freibeträge nicht mehrmals geltend gemacht werden können. Gleichzeitig aber haben kleine und mittlere Erbschaften und Schenkungen eine dämpfende Wirkung auf die Vermögenskonzentration, also die relative Ungleichheit. Daher sollten die Freibeträge bei der Erbschaft-und Schenkungsteuer – auch vor dem Hintergrund der zunehmenden Zahl von Patchworkfamilien – gleichmäßiger über die verschiedenen Personengruppen und Verwandtschaftsgrade verteilt werden.

description: We prove a conjecture of P. Guillon and G. Richard by showing that cellular automata that eventually fix all cells to a fixed symbol 0 are nilpotent on S^Z^d for all d. We also briefly discuss nilpotency on other subshifts, and show that weak nilpotency implies nilpotency in all subshifts and all dimensions, since we do not know a published reference for this.

Excellence in educational leadership : appreciative leadership within BC community colleges
Creators: name: Weegar, Thomas
Publisher: name: University of British Columbia
Year: 2013

description: This study explores Appreciative Leadership as it is being practiced by college educational leaders in British Columbia. Appreciative Leadership in education is a unique, strength-based approach to leadership which focuses continually on capacity-building and seeing possibilities and opportunities. Appreciative Leadership in education is, I argue, an approach that could help address the leadership “skills shortages” and the challenges facing BC colleges in the twenty-first century. Conceptually, the research is informed by a social constructivist approach to educational leadership and how leadership is an area of practice distinct from management. The notion of Appreciative Leadership, a relatively new and emerging concept in relation to educational discourse, is carefully considered in relation to the larger conversation about educational leadership and conceptions of power. Appreciative Leadership, Appreciative Intelligence, and the Five Core Strategies of Appreciative Leadership are central elements of this study. This study involved three stages: 1) a pilot study of my survey instrument among three community college educational leaders; 2) a questionnaire sent to 25 BC community college leaders (Deans, Vice-Presidents – Education [or Academic], Associate Vice-Presidents, Education, and Presidents); and 3) follow-up interviews with a select number of survey respondents where further explorations about the practices of Appreciative Leadership and shared leadership were discussed. The study developed three empirical assertions about Appreciative Leadership in education based on an analysis of the data. First, Appreciative Leadership in education is a gendered practice that requires an exercise of power-with rather than power-over others. Second, Appreciative Leadership in education requires that leaders imagine and create opportunities and are adept at reframing issues in this way. Third, Appreciate Leadership in education requires a productive, creative engagement with conflict (as opposed to avoiding conflict entirely or trying to “placate” it through rationalistic conflict-resolution strategies). This research contributes to the emerging theory around Appreciative Leadership and specifically for educational contexts.
Shear viscosity due to phonons in superfluid neutron stars

description: We compute the contribution of phonons to the shear viscosity $η$ in superfluid neutron stars, assuming neutron pairing in a $^1S_0$ channel. We use a Boltzmann equation amended by a collision term that takes into account the binary collisions of phonons. We use effective field theory techniques to extract the phonon scattering rates, written as a function of the equation of state (EoS) of the system. Our formulation is rather general, and can be used to extract the shear viscosity due to binary collisions of phonons for other superfluids, such as the cold Fermi gas in the unitarity limit. We find that $η\propto 1/T^5$, the proportionality factor depending on the EoS of the system. Our results indicate that the phonon contribution to $η$ cannot be ignored and might have relevant effects in the dynamics of the different oscillation modes of the star.
