Hirundo spilodera

description: Hirundo spilodera Sundevall, 1850: 108.
 VERBATIM TYPE LOCALITY: not given; but within “ trakten kring sjelfva Capstaden ” + “ Cafferlandet ” according to the Swedish introduction.
 CURRENT STATUS: Petrochelidon spilodera (Sundevall, 1850); Hirundinidae (Dickinson & Christidis 2014: 477).
 STATUS REFERENCE: Sclater (1930: 581) and (Peters 1960b: 120; monotypic, in the genus Petrochelidon), White (1961: 60; polytypic in the genus Hirundo and includes P. rufigula Bocage, 1878, and P. preussi Reichenow, 1898), Clancey et al. (1980: 159) and Keith et al. (1992: 165–167; monotypic in the genus Hirundo).
TYPE REFERENCE: Sundevall (1850: 108), in his brief type description, gave no indication that he had more than a single specimen. His acquisition catalogue however shows that he actually had five specimens available. Gyldenstolpe (1926: 69) referred to NRM 569774 [7088] as a “type”, here treated as a lectotype designation of this adult male collected 27 October 1844, south of the Vals (Valsch) River, Free State. The four paralectotypes are: NRM 537971 [7089], a mount of a female collected 15 August 1843 near Mooi River; NRM 90145225 [7087], an adult male collected 8 April 1842 at Tswaing (Saltpannen); RMNH. AVES.90707 [7086], an adult male collected 1 November 1841 at Rhinoster (Renoster River) sent on exchange to Leiden in 1850; and a juvenile female [1790], collected 8 April 1842 at Tswaing and exchanged to Berlin in 1853 (but no longer in the ZMB collection).
VERIFIED TYPE LOCALITY: Vals (Valsch) River, Free State.
 COMMENTS: Sundevall noted the locality from Wahlberg as “Caffr. [Fallo Rev.]”. Gyldenstolpe gave the locality as “Mooi River”(1926:69),“Valsch River,E.of Kroonstad” (1934: 292) and “S. of Valsch River” (Wahlberg). Wahlberg noted in his journal that on 24 October he started from “Mooye” River (= Potchefstroom) “…. and so pressed for time that no chance for collecting presented itself. Pass the Fals (Vals) River [on 24 October] ”. There are no notes for the days 25–29 October; for 30 October–1 November the only information is “rainy” for the three days. On 2 November he descended the Drakensberg [via Bezuidenhout’s Pass]. Although there is no definite locality where the type of Hirundo spilodera was collected,Gyldenstolpe’s correction is probably as close as any other, and the restricted type locality should stand.

description: We investigate the effects of a magnetic field on the thermodynamics of a neutron system at finite density and temperature. Our main motivation is to deepen the understanding of the physics of a class of neutron stars known as magnetars, which exhibit extremely strong magnetic fields. Taking into account two facts, (i) the existence of a pressure anisotropy in the presence of a magnetic field and (ii) that the quantum field theory contribution to the pressure is non-negligible, we show that the maximum value that the inner magnetic field of a star can reach while being in agreement with the magnetohydrostatic equilibrium between the gravitational and matter pressures becomes $10^{17}$ G, an order of magnitude smaller than the previous value obtained through the scalar virial theorem; that the magnetic field has a negligible effect on the neutron system's equation of state; that the system's magnetic susceptibility increases with the temperature; and that the specific heat $C_V$ does not significantly change with the magnetic field in the range of temperatures characteristic of protoneutron stars.

description: We construct generating solutions for general D-dimensional ($4 \le D \le 9$) rotating, electrically charged, black holes in the effective action of toroidally compactified heterotic (or Type IIA) string. The generating solution is parameterized by the ADM mass, two electric charges and $[{D-1}\over 2]$ angular momenta (as well as the asymptotic values of one toroidal modulus and the dilaton field). For $D \ge 6$, those are generating solutions for {\it general} black holes in toroidally compactified heterotic (or type IIA) string. Since in the BPS-limit (extreme limit) these solutions have singular horizons or naked singularities, we address the near extreme solutions with all the angular momenta small enough. In this limit, the thermodynamic entropy can be cast in a suggestive form, which has a qualitative interpretation as microscopic entropy of (near)-BPS-saturated charged string states of toroidally compactified heterotic string, whose target-space angular momenta are identified as $[{{D-1}\over 2}]$ U(1) left-moving world-sheet currents.

description: The intrinsic strength of the Ly$α$ line in young, star-forming systems makes it a special tool for studying high-redshift galaxies. However, interpreting observations remains challenging due to the complex radiative transfer involved. Here, we combine state-of-the-art hydrodynamical simulations of 'Althaea', a prototypical Lyman Break Galaxy (LBG, stellar mass $M_{\star}$$\simeq$ $10^{10}{\rm M}_{\odot})$ at $z=7.2$, with detailed radiative transfer computations of dust/continuum, [CII] 158 $μ$m, and Ly$α$ to clarify the relation between the galaxy properties and its Ly$α$ emission. Althaea exhibits low ($f_α< 1\%$) Ly$α$ escape fractions and Equivalent Widths, EW $\lesssim 6$ Angstrom for the simulated lines of sight, with a large scatter. The correlation between escape fraction and inclination is weak, as a result of the rather chaotic structure of high-redshift galaxies. Low $f_α$ values persist even if we artificially remove neutral gas around star forming regions to mimick the presence of HII regions. The high attenuation is primarily caused by dust clumps co-located with young stellar clusters. We can turn Althaea into a Lyman Alpha Emitter (LAE) only if we artificially remove dust from the clumps, yielding EWs up to $22$ Angstrom. Our study suggests that the LBG-LAE duty-cycle required by recent clustering measurements poses the challenging problem of a dynamically changing dust attenuation. Finally, we find an anti-correlation between the magnitude of Ly$α$-[CII] line velocity shift and Ly$α$ luminosity.

Official Historiography, Political Legitimacy, Historical Methodology, and Royal and Imperial Authority in Spain under Phillip II, 1580-99
Creators: von Ostenfeld, Kira K.
Publisher: name: Columbia University
Year: 2014
Subjects: History

description: Between 1580 and 1599, Spain was the subject of a barrage of foreign polemical attacks, a reaction to Spain's European hegemony under Philip II. These attacks used historical arguments to directly challenge Spain's political legitimacy and power, its reputation, and its political standing within Europe by criticizing Spain's dynastic arguments for empire, and denigrated Spanish imperialism and the nature of Spanish rule, threatening constitutional structures by claiming that Philip ruled as a tyrant. In response to these attacks, a coterie of scholars and powerful political advisors, seeking to solidify claims to certain territories and to justify imperial actions, developed innovative historical writing practices that were effective ideological tools for creating support for new political ideas. To convincingly defend Spanish imperialism and restore Spanish reputación, official history needed to concern itself with questions of statecraft, and to do so within the framework of humanist notions of "good" history. Specifically, the new type of historical writing used humanist and antiquarian methodologies, especially an emphasis on source-based documentation of arguments and claims, and combined these with reason of state politics to respond to European challenges to Spanish imperial authority and Spanish actions in Portugal and France by ensuring that only a very specific image of the king was conveyed, and very specific sources were utilized and revealed. In doing so, official historians, most notably Antonio de Herrera y Tordesillas, Esteban de Garibay, and Gregorio López de Madera, and advisors, like Juan de Idiáquez and Cristóbal de Moura, turned to the writing of history not as a means to reform the state, but instead as a potent means to bolster and defend the existing state's identity and advance its purpose. This dissertation uses court correspondence, the treatises on the artes historicae written by the court historians, and the innovative official histories they produced to show how the tensions between ideology and methodology played out in this new form of official history, and how theory and practice came together in the service of power. Through its use of multiple sources of data, this study shows that it was due to the polemical context, not despite it, that a new and more powerful history emerged, which included new practices and cultivated a more critical sensibility. Official history came to play a role in giving conceptual identity and political legitimacy to Spain's imperial ambitions in a new reason of state context. Thus, notions of rule (Spanish Christian reason of state) and provisions of proof became the two pivots upon which Spanish imperial ambitions were justified, and larger debates about how to legitimize formal rights and privileges found a concrete form of expression in official history.

description: Tight constraints on the abundance of primordial black holes can be deduced across a vast range of masses, with the exception of those light enough to fully evaporate before nucleosynthesis. This hypothetical population is almost entirely unconstrained, to the point where the early Universe could pass through a matter-dominated phase with primordial black holes as the primary component. The only obvious relic of this phase would be Hawking radiated gravitons which would constitute a stochastic gravitational wave background in the present-day Universe, albeit at frequencies far beyond the scope of any planned detector technology. This paper explores the effects of classical mergers in such a matter dominated phase. For certain ranges of parameters, a significant fraction of the black holes merge, providing an additional, classical source of primordial gravitational waves. The resulting stochastic background typically has a lower amplitude than the Hawking background and lies at less extreme frequencies, but is unlikely to be easily detectable, with a maximal present day density of $Ω_{GW} \sim 10^{-12}$ and frequencies between $10^{15} - 10^{19}$ Hz. We also asses the impact of radiation accretion on the lifetimes of such primordial black holes and find that it increases the black hole mass by $\sim 14 \%$ and the lifetimes by about $50 \%$. However, this does not qualitatively change any of our conclusions.

description: In this work we perform an investigation of the flux tube between two static color sources in four dimensional $SU(3)$ Yang-Mills theory, using the so called connected correlator. Contrary to most previous studies we do not use any smoothing algorithm to facilitate the evaluation of the correlator, that is performed using only stochastically exact techniques. We first examine the renormalization properties of the connected operator, then we present our numerical data for the longitudinal chromoelectric component of the flux tube, that are used to extract the dual superconductivity parameters.

description: Hirundo semirufa Sundevall, 1850: 107.
 VERBATIM TYPE LOCALITY: “ Hab. in Caffraria superiore.”
 CURRENT STATUS: Cecropis semirufa semirufa (Sundevall, 1850); Hirundinidae (Dickinson & Christidis 2014: 478).
TYPE MATERIAL: Sundevall, in his brief original description (1850: 107) gave no indication that he had more than a single specimen at hand. His acquisition catalogue, however, shows that there were two skins available. Gyldenstolpe (1926: 68–69) referred to NRM 569780 [7076] as a “type”, here treated as a lectotype designation of this study skin of a male collected 18 November 1841 at Magaliesberg. The paralectotype, NRM 90144785 [7077], is a female collected 11 December 1841 at Magaliesberg.
VERIFIED TYPE LOCALITY: Magalies Berge, junction of Hennops River and Crocodile River, southwest of Pretoria, Gauteng Province.
 COMMENTS: The only entry in Wahlberg’s journal for this day (18 November 1841) is “fully occupied”. However, he recorded collecting a specimen of “ Hirundo senegalensis ” [in error for Hirundo (Cecropis) semirufa] at Mooi River (Potchefstroom) on 8 November and then another specimen on 14 November on the southern edge of the Magaliesberg, close to Hartebeespoort. The Potchefstroom specimen has not been located in the collections. The restricted type locality suggested by Gyldenstolpe (1934) is unlikely. The confluence between the Crocodile and Hennops Rivers is well south of the track that Wahlberg was thought to have used when travelling from Holfontein to Hartebeesport (map B, p. 129 in Craig & Hummel 1992). If the type was collected on 18 November, the TL should be restricted to Hartebeespoort. If the type was collected on 14 November 1841, Wahlberg was camped at “Herman Potgieter’s farm” at Olifantsnek on this day and reached Hartebeespoort on the 15 November (see “Problems with labels and collecting localities” in the Introduction).

Old Myths and New Forms of Orientalism: Gauguin, Toorop, van der Leck, and Mondrian
Creators: Roustayi, Mina S. M.
Publisher: name: Columbia University
Year: 1998
Subjects: Art

description: More than fifty examples of works by Paul Gauguin, Jan Toorop, Bart van der Leck, and Piet Mondrian demonstrate the significant influence of artifacts, newly revealed since the early nineteenth century, from the ancient Orient, that is, Pharaonic Egypt and biblical lands. The individual interest of these artists is analyzed in four monographic chapters, which indicate enough similarities in their interpretation and use of the ancient motifs to constitute a new departure in Orientalism. Their particular approaches bring out as well particular biographical, symbolic, and iconographic insights into their artistic development. As a leading symbolist painter, Gauguin pioneered the revival of sacred art involving old and new myths of Orientalism, which were critical also for Toorop, van der Leck, and Mondrian. Characteristically, all four artists assimilated ancient Oriental artistic conventions as a form of primitivism a return to original purity -- to create radical images about personal and social renewal. The primordial figured also in the narrative and symbolic synthesis of their art. Stylistically, all of their work became more decorative, two-dimensional, and more compatible with the architectural plane; line and color were released from mimetic servitude, and a pictographic aspect was added. Gauguin, Toorop, van der Leck, and Mondrian all integrated ancient Oriental motifs into their work, but each to his own ends. While Gauguin appropriated Achaemenid Persian and Egyptian art, van der Leck studied Egyptian, Assyrian, and Sumerian art, and Toorop and Mondrian relied on Egyptian art. Though Gauguin discussed music as a paradigm in the new art, the musical quality of Egyptian and Assyrian (and even Sumerian) art made a greater impact on the work of the Dutch artists. Likewise, they embraced the social and mural tradition of ancient Oriental art as a model for their own attempts to reintegrate architecture with utopian art. The dissertation has answered my original question regarding the impact of ancient Oriental art on progressive artists at the turn of the century. The project has also brought surprises, in the form of many unexpected connections between artists and other members of the European intelligentsia, which merit further exploration.

Probing nonstandard lepton number violating interactions in neutrino oscillations

description: We discuss lepton number violating processes in the context of long-baseline neutrino oscillations. We summarise and compare neutrino flavour oscillations in quantum mechanics and quantum field theory, both for standard oscillations and for those that violate lepton number. When the active neutrinos are Majorana in nature, the required helicity reversal gives a strong suppression by the neutrino mass over the energy, $(m_ν/E_ν)^{2}$. Instead, the presence of non-standard lepton number violating interactions incorporating right-handed lepton currents at production or detection alleviate the mass suppression while also factorising the oscillation probability from the total rate. Such interactions arise from dimension-six operators in the low energy effective field theory of the Standard Model. We derive general and simplified expressions for the lepton number violating oscillation probabilities and use limits from MINOS and KamLAND to place bounds on the interaction strength in interplay with the unknown Majorana phases in neutrino mixing. We compare the bounds with those from neutrinoless double beta decay and other microscopic lepton number violating processes and outline the requirements for future short- and long-baseline neutrino oscillation experiments to improve on the existing bounds.

description: On Mt. Washington, Vancouver Island, Pyrrhotite Creek was diverted into the Spectacle Wetland as a passive remediation technique to reduce the amount of copper running into the Tsolum River. The objective of this report is to determine the concentration of loaded copper in Spectacle Wetland. We designed a systematic methodology for sampling the sediments found in the inflow, riparian, sandbars and outflow. In the Camosun College chemistry lab, the sediment underwent an Aqua Regia digestion, which removed the majority of the copper ions attached to the sediment. The samples were analyzed using an AA Spectrophotometer to determine the concentration of copper. These results underwent various statistical and visual analyses using Minitab, Ecological Methodology and Arcview GIS software. The lowest copper concentrations were found in the southeast arm of the lake, whereas higher concentrations were found throughout the rest of the lake, particularly in the outflow areas. Moderate copper concentrations were found in the inlet area, particularly in the riparian, sand bar, and stream fan areas. It can be demonstrated that high concentrations of copper are present in Spectacle Wetland. With more rigorous sampling and monitoring, for example, coring and residence time of the copper, the functionality of the wetland could be better determined.

description: Context. Stellar magnetic fields are one of the candidates often invoked to explain the missing transport of angular momentum observed in the models of stellar interiors. However, the properties of an internal magnetic field and the consequences of its presence on stellar evolution are largely unknown. Aims. We study the effect of an axisymmetric internal magnetic field on the frequency of gravity modes in rapidly rotating stars to check whether gravity modes can be used to detect and probe such a field. Methods. Rotation is taken into account using the traditional approximation of rotation and the effect of the magnetic field is computed using a perturbative approach. As a proof of concept, we compute frequency shifts due to a mixed (i.e. with both poloidal and toroidal components) fossil magnetic field for a representative model of a known magnetic, rapidly rotating, slowly pulsating B-type star, namely HD 43317. Results. We find that frequency shifts induced by the magnetic field scale with the square of its amplitude. A magnetic field with a near-core strength of order 150 kG (which is consistent with the observed surface field strength of order 1 kG) leads to signatures that are detectable in period spacings for high-radial-order gravity modes. Conclusions. The predicted frequency shifts can be used to constrain internal magnetic fields and offers the potential for a significant step forward in our interpretation of the observed structure of gravity-mode period spacing patterns in rapidly rotating stars.

description: We compute an upper bound on the circuit complexity of quantum states in $3d$ Chern-Simons theory corresponding to certain classes of knots. Specifically, we deal with states in the torus Hilbert space of Chern-Simons that are the knot complements on the $3$-sphere of arbitrary torus knots. These can be constructed from the unknot state by using the Hilbert space representation of the $S$ and $T$ modular transformations of the torus as fundamental gates. The upper bound is saturated in the semiclassical limit of Chern-Simons theory. The results are then generalized for a family of multi-component links that are obtained by "Hopf-linking" different torus knots. We also use the braid word presentation of knots to discuss states on the punctured sphere Hilbert space associated with 2-bridge knots and links. The calculations present interesting number theoretic features related with continued fraction representations of rational numbers. In particular, we show that the minimization procedure defining the complexity naturally leads to regular continued fractions, allowing a geometric interpretation of the results in the Farey tesselation of the upper-half plane. Finally, we relate our discussion to the framework of path integral optimization by generalizing the original argument to non-trivial topologies.

description: While the radio detection of cosmic rays has advanced to a standard method in astroparticle physics, the radio detection of neutrinos is just about to start its full bloom. The successes of pilot-arrays have to be accompanied by the development of modern and flexible software tools to ensure rapid progress in reconstruction algorithms and data processing. We present NuRadioReco as such a modern Python-based data analysis tool. It includes a suitable data-structure, a database-implementation of a time-dependent detector, modern browser-based data visualization tools, and fully separated analysis modules. We describe the framework and examples, as well as new reconstruction algorithms to obtain the full three-dimensional electric field from distributed antennas which is needed for high-precision energy reconstruction of particle showers.

description: In the continuum, a topological obstruction to the vanishing of the non-abelian anomaly in 2n dimensions is given by the index of a certain Dirac operator in 2n+2 dimensions, or equivalently, the index of a 2-parameter family of Dirac operators in 2n dimensions. In this paper an analogous result is derived for chiral fermions on the lattice in the Overlap formulation. This involves deriving an Index Theorem for a family of lattice Dirac operators satisfying the Ginsparg--Wilson relation.

description: Observations reveal the presence of supermassive black holes (SMBH) as early as ~700 million years after the Big Bang. Their formation path is still subject to current debate. We explore the influence of magnetic fields, which are strongly amplified via the turbulent small-scale dynamo, on the formation of SMBH seeds within the direct collapse scenario. In this study, we perform for the first time cosmological magnetohydrodynamic large eddy simulations that employ a model for unresolved, compressible MHD turbulence. In total we perform 36 simulations for 9 haloes each with two different initial magnetic field strengths, and with and without employing the unresolved turbulence model. We make use of the adaptive mesh refinement approach to achieve an effective spatial resolution of less than one proper astronomical unit. We consider a regime where cooling is regulated by atomic hydrogen and the molecular hydrogen gets dissociated by a strong radiation field. Our main finding is that the majority of the gas properties in the haloes at the final output are predominantly determined by the run-away gravitational collapse. Turbulence is supersonic and super-Alfvénic in all cases, and magnetic fields are amplified to an approximately dynamically relevant regime. Finally, fragmentation during the collapse is intermittent and mass accretion rates range from 0.2-3 Msun/yr. This suggests that the presence of strongly amplified magnetic fields and turbulence provides additional pressure support on small scales and make the direct collapse a viable scenario for the formation of massive objects under the required ambient conditions.

description: Although energy models advance rapidly in terms of technical and techno-economic details, social and political aspects and environmental burdens beyond greenhouse gas emissions are currently underrepresented. However, in light of the European Green Deal and the EU Energy Union Strategy, models must advance in terms of social and environmental considerations to support decision- and policymakers in adequately addressing that environmental burden and to put “citizens at its core” of the energy transition. In this deliverable, we present key user-needs for environmental and social aspects that need to be better represented in energy system models (Section 2), and how we have developed and adapted the modelling tools ENVIRO, QTDIAN, and ATOM in response to the identified user needs. We show three main user needs regarding social aspects, specifically (i) social impacts on energy politics and policies, (ii) the social acceptance of energy technologies and infrastructure, and (iii) consumers’ behavior in energy models. We furthermore show that users consider relevant the following factors within the environmental aspects of energy scenarios: (iv) demand of raw materials/ circularity, (v) the implications on nature and biodiversity, as well as (vi) full life-cycle impacts and externalization. ENVIRO and QTDIAN are being developed within SENTINEL in a participatory process by engaging with stakeholders in the information and development stages of the model implementation. In contrast, ATOM is adapted by considering user-needs especially in the implementation stage. We conclude that we have benefited from the insights of model users and other stakeholders, and that this will allow us to make our modelling tools fit-for-purpose. All three modelling tools will support decision-makers by answering the most important of the questions users have risen within the SENTINEL stakeholder engagement process. Model-linking within the WP2 and other WPs will ensure that the understanding of environmental and social aspects is strengthened in energy system models and will be embedded in the overall SENTINEL platform.
Exploring Simple Catalyst for Transfer Hydrogenation of Ketones and Photocatalytic Hydrogen Production Using Homogeneous Metal Complexes

description: Transfer hydrogenation has been recognized to be an important synthetic method in both academic and industrial research to obtain valuable products including alcohols. Transition metal catalysts based on precious metals, such as Ru, Rh and Ir, are typically employed for this process. This thesis starts with a study on the potential of an Fe based complex carrying a PNP ligand (2,6-{Ph2PNH}2(NC5H3)) to function as an active transfer hydrogenation catalyst for the conversion of ketones to alcohols. During the analysis of the performance parameters of this potential catalyst, it was discovered that the added base, KOtBu, was the actual catalyst. Other bases were explored as catalysts for this transformation as well as the general performance features of this simple alkali metal base. In a separate project described in Chapter 3, the search for catalysts shifted focus to a study of the potential of a series of first row transition metal-based complexes supported by a bis(thioether)pyridine “SNS” ligand for photocatalytic hydrogen production. This initial study led to the observation that the Fe complex [Fe(k3-2,6-(CH3SCH2)2C5H3N)Br2]2 was a capable photocatalyst for H2 production in combination with a photosensitizer (Ru(bpy)3)2+) and an electron donor (triethanolamine). Although water was initially believed to be the source of protons that were reduced to H2, analysis of control experiments pointed to the hydrogen source being the electron donor.
Quantum Key Distribution with no Shared Reference Frame

description: Any quantum communication task requires a common reference frame (i.e. phase, coordinate system). In particular, Quantum Key Distribution requires different bases for preparation and measurements of states which are obviously based on the existence of a common frame of reference. Here we show how QKD can be achieved in the absence of any common frame of reference. We study the coordinate reference frame, where the two parties do not even share a single direction, but the method can be generalized to other general frames of reference, pertaining to other groups of transformations.

description: We investigate the large $N$ behavior of the complex solutions for the two magnon system in the S=1/2 Heisenberg XXZ model. The Bethe ansatz equations are numerically solved for the string solutions with new iteration method. A clear evidence of the violation of the string configurations is found at $N=22,62,121,200,299,417$, but the broken states are still Bethe states. The number of the Bethe states is consistent with the exact diagonalization, except one singular state.

Olympic Transportation Planning: The Legacies of Barcelona and Beijing
Creators: Joaquin, Doneliza
Publisher: name: Columbia University
Year: 2012
Subjects: Transportation--Planning

description: Being selected as a host city for a sports mega-event such as the Olympics is both a gift and a burden. Host cities are thrust into the international spotlight and must provide the stadiums, housing, transportation, and crowd management needed for the games. This thesis addresses the mega-event transportation legacy by asking whether it is possible for Olympic host cities to utilize the event for transportation development that both supports high volumes of movement during the Games and aligns with the long-term goals of the city's transportation plan. I analyzed the strategies of Barcelona, host of the 1992 Summer Olympics and Beijing, host of the 2008 Summer Olympics, as case studies of their transportation planning pre-Games and post-Games. I find that for a successful legacy, a city's Olympic bid for transportation changes should align with its pre-Olympic plan, drawing from projects already proposed, and the strategic placement of their Olympic venues, rather than relying on creating solely new projects or new locations for development. Additionally, while large infrastructural projects might be part of some city's long-term goals, a successful Olympic transportation legacy does not always require large infrastructure development. While cities must appeal to the International Olympic Committee in their bids, potential hosts should be critical of whether proposed projects have benefits in both the short- and long-term.

description: Renewable energy, particularly solar energy, is a rapidly expanding field that is poised to address pressing global energy challenges. As energy demands rise, preparing future generations to leverage solar energy becomes important. However, traditional teaching methods in solar energy system design using simulations often offer limited practical interaction, poor integration of theoretical and practical learning and low learner engagement and motivation.

Virtual reality (VR) has emerged as a transformative technology for training and learning across various sectors due to its ability to replicate real-world scenarios and enhance user experience through immersive and interactive environments. This thesis investigates the application of VR in designing solar energy systems using computer based simulations, aiming to improve conventional methods by harnessing the “feeling of presence” unique to VR, which has been shown to promote high learner engagement. Therefore, the primary contributions of this research include:
• The development of innovative VR visualisations tailored for solar energy system design, enhancing the comprehension and interaction with complex solar configurations. 
• A robust framework for evaluating VR applications in educational settings, focusing on engagement, enjoyment and technology acceptance. 
• Guidance for developers and designers to optimise VR applications that aim to promote sustainability, thereby enriching the user experience and educational outcomes.

Methodologically, my thesis used a mixed-methods approach to evaluate the effectiveness of these VR environments. I incorporated qualitative data from surveys alongside quantitative physiological data gathered from wearable sensors and eye-tracking technology to assess user engagement and cognitive load. My findings show a strong user preference for integrating VR into solar energy system design, with significant improvements in understanding solar energy systems attributed to VR’s interactive and visual capabilities. Participants reported higher levels of engagement and interest when using VR compared to traditional learning methods.

In conclusion, my thesis demonstrates the potential of VR as a pivotal educational tool in the renewable energy sector, offering an immersive alternative that could replace conventional teaching methods and substantially enhance learner engagement and comprehension.
On A Snowy Night: Yishan Yining (1247-1317) and the Development of Zen Calligraphy in Medieval Japan

description: This dissertation is the first monographic study of the monk-calligrapher Yishan Yining (1247-1317), who was sent to Japan in 1299 as an imperial envoy by Emperor Chengzong (Temur, 1265-1307. r. 1294-1307), and achieved unprecedented success there. Through careful visual analysis of his extant oeuvre, this study situates Yishan’s calligraphy synchronically in the context of Chinese and Japanese calligraphy at the turn of the 14th century and diachronically in the history of the relationship between calligraphy and Buddhism. This study also examines Yishan’s prolific inscriptional practice, in particular the relationship between text and image, and its connection to the rise of ink monochrome landscape painting genre in 14th century Japan. This study fills a gap in the history of Chinese calligraphy, from which monk-calligraphers and their practices have received little attention. It also contributes to existing Japanese scholarship on bokuseki by relating Zen calligraphy to religious and political currents in Kamakura Japan. Furthermore, this study questions the validity of the “China influences Japan” model in the history of calligraphy and proposes a more fluid and nuanced model of synthesis between the wa and the kan (Japanese and Chinese) in examining cultural practices in East Asian culture.
