title: Bridging Canadian Business Lending and Market-Based Risk Measures
Creators: name: Ouellet Leblanc, Guillaume
name: Leboeuf, Maxime
Publisher: name: Bank of Canada
Year: 2019

description: Lending to business is central to economic growth because it supports investment by firms. Knowing how market participants view risk in the financial system can give the Bank of Canada information about future growth in business loans. In this note, we look at three market-based risk measures and find that sudden increases in the perception of risk in the Canadian banking system are associated with a weaker outlook for business loans and real gross domestic product.

description: Les prêts aux entreprises sont au cœur de la croissance économique, car ils permettent de financer les investissements de ces dernières. Le fait de savoir comment les participants au marché perçoivent le risque qui pèse sur le système financier peut donner à la Banque du Canada des indications sur la croissance future des prêts aux entreprises. Dans la présente note analytique, nous examinons trois mesures du risque fondées sur le marché et constatons que les hausses soudaines du risque perçu dans le système bancaire canadien sont associées à un assombrissement des perspectives des prêts aux entreprises et du produit intérieur brut réel.

title: MS Varia 131 of the Biblioteca Reale di Torino and Decembrio's Translation of Curtius Rufus
Creators: name: Ponzù Donato, Paulo
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: This article offers a new insight on the manuscript Varia 131 of the Biblioteca Reale di Torino, the earliest known copy of Pier Candido Decembrio’s vernacular translation of Curtius Rufus’s Historia Alexandri Magni, which was transcribed in 1438 by the Milanese scribe Thomas Guarimbertus and was corrected by Decembrio himself. This manuscript is notable not only for its sumptuous illumination by the Master of the Vitae imperatorum (probably the finest illuminator in early fifteenth-century Lombardy) or its dedicatee (the Spanish knight Iñigo d’Avalos), but also for being one of the first examples of the use of the humanistic littera antiqua to copy a vernacular text. Because of these unique features, the Turin manuscript is an outstanding testimony of the reputation of the vernacular in the Visconti court.

description: Mexican organized labor represents a unique case in Latin America. The Mexican Revolution that began in 1910 absorbed or channelized the organizing efforts that had preceded it. Succeeding regimes integrated organized labor into the governmental structure as one of its basic supports. During the Cárdenas administration, 1934-1940, this arrangement was given its definitive form. Debate continues on how deeply corrupted this official system has become, how real its benefits to the workers are, and how broad and significant the resistance to it has been.

description: Central Americans constitute a rapidly growing segment of the population in Mexico and the United States. Their presence has become more apparent since the early 1980s when several hundred thousand Guatemalans, Nicaraguans and Salvadorans fled war-torn Central America. To date very few studies have been done on the acculturation of Central Americans into American society; instead their concentrate on immigration policy, migration, and refugees. More studies have been written on the integration of refugees into Mexican society. This bibliography lists many sources in which information about Central Americans in both Mexico and the United States can be found. The sources are located in the Benson Latin American Collection.

description: Current fluctuations in pure lipid membranes have been shown to occur under the influence of transmembrane electric fields (electroporation) as well as a result from structural rearrangements of the lipid bilayer during phase transition (soft perforation). We demonstrate that the ion permeability during lipid phase transition exhibits the same qualitative temperature dependence as the macroscopic heat capacity of a D15PC/DOPC vesicle suspension. Microscopic current fluctuations show distinct characteristics for each individual phase state. While current fluctuations in the fluid phase show spike-like behaviour of short time scales (~ 2ms) with a narrow amplitude distribution, the current fluctuations during lipid phase transition appear in distinct steps with time scales in the order of ~ 20ms. 1 We propose a theoretical explanation for the origin of time scales and permeability based on a linear relationship between lipid membrane susceptibilities and relaxation times in the vicinity of the phase transition.

Supplemental material from Language matters: how normative expressions shape norm perception and affect norm compliance

Subjects: classificationCode: 310901
subject: Animal behaviour

description: Previous studies have used various normative expressions such as ‘should’, ‘appropriate’ and ‘approved’ interchangeably to communicate injunctions and social norms. However, little is known about whether people's interpretations of normative language differ and whether behavioural responses might vary across them. In two studies (total N = 2903), we find that compliance is sensitive to the types of normative expressions and how they are used. Specifically, people are more likely to comply when the message is framed as an injunction rather than as what most people consider good behaviour (social norm framing). Behaviour is influenced by the type of normative expression when the norm is weak (donation to charities), not so when the norm is strong (reciprocity). Content analysis of free responses reveals individual differences in the interpretation of social norm messages, and heterogeneous motives for compliance. Messages in the social norm framing condition are perceived to be vague and uninformative, undermining their effectiveness. These results suggest that careful choice of normative expressions is in order when using messages to elicit compliance, especially when the underlying norms are weak.This article is part of the theme issue ‘Social Norm Change: From Evolution to Policy Intervention’.

description: We report heat capacity measurements of the pnictide materials SmFeAsO$_{1-x}$F$_x$, NdFeAsO, LaFeAsO$_{1-x}$F$_x$ and LiFeAs. For SmFeAsO$_{1-x}$F$_x$, with x close to 0.1, we use 3 He measurements to demonstrate a transfer of entropy from the peak at TN to a previously unidentified ~2 K feature which grows with increasing doping. Our results on the Sm samples are compared with a similarly doped La sample to elucidate the crystal field levels of the Sm3+ ion at 0, 23, and 56 meV which lead to a Schottky-like anomaly, and also show that there is a significant increase in the Sommerfeld coefficient $γ$ when La is replaced by Sm or Nd. The lattice contribution to the heat capacity of the superconducting oxypnictides is found to vary negligibly with chemical substitution. We also present a heat capacity measurement of LiFeAs showing the feature at Tc, which is significantly rounded and much smaller than the BCS value.

description: The first phase of stellar evolution in the history of the Universe may be Dark Stars, powered by dark matter heating rather than by nuclear fusion. Weakly Interacting Massive Particles, which may be their own antipartners, collect inside the first stars and annihilate to produce a heat source that can power the stars for millions to billions of years. In this paper we show that these objects can grow to be supermassive dark stars (SMDS) with masses $\gtrsim (10^5-10^7) \msun$. The growth continues as long as dark matter heating persists, since dark stars are large and cool (surface temperature $\lesssim 5\times 10^4$K) and do not emit enough ionizing photons to prevent further accretion of baryons onto the star. The dark matter may be provided by two mechanisms: (1) gravitational attraction of dark matter particles on a variety of orbits not previously considered, and (2) capture of WIMPs due to elastic scattering. Once the dark matter fuel is exhausted, the SMDS becomes a heavy main sequence star; these stars eventually collapse to form massive black holes that may provide seeds for supermassive black holes in the Universe. SMDS are very bright, with luminosities exceeding $(10^9-10^{11}) L_\odot$. We demonstrate that for several reasonable parameters, these objects will be detectable with JWST. Such an observational discovery would confirm the existence of a new phase of stellar evolution powered by dark matter.

description: The model of random interlacements on Z^d, d bigger or equal to 3, was recently introduced in arXiv:0704.2560. A non-negative parameter u parametrizes the density of random interlacements on Z^d. In the present note we investigate the connectivity properties of the vacant set left by random interlacements at level u, in the non-percolative regime, where u is bigger than the non-degenerate critical parameter for percolation of the vacant set, see arXiv:0704.2560, arXiv:0808.3344. We prove a stretched exponential decay of the connectivity function for the vacant set at level u, when u is bigger than an other critical parameter. It is presently an open problem whether these two critical parameters actually coincide.

Rounding errors in digital computer arithmetic subroutines.
Creators: name: Lastman, Gary Joseph
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis we investigate arithmetic subroutines and round-off procedures. An error analysis of single operations in normalized floating point arithmetic leads us to the construction of an improved form of addition-subtraction subroutine. In addition the properties of several types of round-off procedures are examined (adding ½; adding random digits; dropping digits). The experimental work (using the above mentioned subroutines) with the system x• = y, y• = -x shows that the systematic accumulation of round-off error observed by Huskey is due to the type of rounding-off procedure used. Furthermore, Hartree's explanation of this effect is found to be inadequate because carrying extra digits throughout the calculations does not eliminate the systematic round-off.

description: Graph G is the square of graph H if two vertices x, y have an edge in G if and only if x, y are of distance at most two in H. Given H it is easy to compute its square H2, however Motwani and Sudan proved that it is NP-complete to determine if a given graph G is the square of some graph H (of girth 3). In this paper we consider the characterization and recognition problems of graphs that are squares of graphs of small girth, i.e. to determine if G = H2 for some graph H of small girth. The main results are the following. - There is a graph theoretical characterization for graphs that are squares of some graph of girth at least 7. A corollary is that if a graph G has a square root H of girth at least 7 then H is unique up to isomorphism. - There is a polynomial time algorithm to recognize if G = H2 for some graph H of girth at least 6. - It is NP-complete to recognize if G = H2 for some graph H of girth 4. These results almost provide a dichotomy theorem for the complexity of the recognition problem in terms of girth of the square roots. The algorithmic and graph theoretical results generalize previous results on tree square roots, and provide polynomial time algorithms to compute a graph square root of small girth if it exists. Some open questions and conjectures will also be discussed.

description: Previously, we have presented a methodology to extend canonical Monte Carlo methods inspired on a suitable extension of the canonical fluctuation relation $C=β^{2}$ compatible with negative heat capacities $C<0$. Now, we improve this methodology by introducing a better treatment of finite size effects affecting the precision of a direct determination of the microcanonical caloric curve $β(E) =\partial S(E) /\partial E$, as well as a better implementation of MC schemes. We shall show that despite the modifications considered, the extended canonical MC methods possibility an impressive overcome of the so-called \textit{super-critical slowing down} observed close to the region of a temperature driven first-order phase transition. In this case, the dependence of the decorrelation time $τ$ with the system size $N$ is reduced from an exponential growth to a weak power-law behavior $τ(N)\propto N^α$, which is shown in the particular case of the 2D seven-state Potts model where the exponent $α=0.14-0.18$.

description: The cost of borrowing Government of Canada treasury bills (t-bills) in the repurchase (repo) market is mainly explained by the relationship between the parties involved. Some pairs of parties conduct most of their repos for t-bills rather than bonds, and at relatively high borrowing costs. We speculate that these pairs have formed a mutually beneficial service relationship in which one party consistently receives t-bills, while the other receives cash at a relatively cheap rate.

description: Les coûts d’emprunt des bons du Trésor du gouvernement du Canada sur le marché des pensions s’expliquent principalement par la relation entre les deux parties à la transaction. Certaines paires effectuent la plupart de leurs opérations de pension sur des bons du Trésor plutôt que sur des obligations, et à un coût d’emprunt relativement élevé. Nous supposons que ces paires ont établi une relation de service mutuellement avantageuse, où l’une des parties reçoit régulièrement des bons du Trésor, et l’autre, de l’argent comptant à un taux d’intérêt relativement bas.

description: A self-similar formalism for the study of the gravitational collapse of molecular gas provides an important theoretical framework from which to explore the dynamics of star formation. Motivated by the presence of elongated and filamentary structures observed in giant molecular clouds, we build upon the existing body of work on cylindrical self-similar collapse flows by including dynamic equations of state that are different from the effective equation of state that produces the initial density distribution. We focus primarily on the collapse of initial states for which the gas is at rest and everywhere overdense from its corresponding hydrostatic equilibrium profile by a factor $Λ$, and apply our results toward the analysis of star formation within dense, elongated molecular cores. An important aspect of this work is the determination of the mass infall rates over a range of the parameters which define the overall state of the gas -- the overdensity parameter $Λ$, the index $Γ$ of the static equation of state, and the index $γ$ of the dynamic equation of state. While most of the parameter space explored in this work leads to solutions for which the underlying equations do not become singular, we do include a discussion on how to treat cases for which solutions pass smoothly through the singular surface. In addition, we also present a different class of collapse solutions for the special case $γ= 1$.

description: We calculate moments of the $O(α_s^3)$ heavy flavor contributions to the Wilson coefficients of the structure function $F_2(x,Q^2)$ in the region $Q^2\gg m^2$. The massive Wilson coefficients are obtained as convolutions of massive operator matrix elements (OMEs) and the known light flavor Wilson coefficients. The calculation of moments of the massive OMEs involves a first independent recalculation of moments of the fermionic contributions to all 3--loop anomalous dimensions of the unpolarized twist--2 local composite operators stemming from the light--cone expansion. The expressions for the massive OMEs are now known for general values of the Mellin variable $N$ apart of one coefficient in the constant term, for which only a series of moments is computed.

title: Reducing Building Water Use Intensity (WUI): Tools for Academia and Practice
Creators: name: Crosson, Courtney
Publisher: name: University of Massachusetts Amherst
Year: 2019

description: Recent prolonged droughts have increased water awareness worldwide, yet limited progress has been made to expand integrated building solutions. This paper investigates the critical tools needed by architectural practice and academia to support water efficient pedagogy and design. A water auditing protocol was developed, tested, and standardized during an undergraduate/graduate architecture water efficiency course over 2017-19. This paper presents the case study implementation of this tool for water use reduction in a commercial building in Tucson, Arizona. The paper ultimately evaluates the success of this new tool through four outcomes from the case study. First, a cutting-edge, service-learning pedagogical model was developed to teach water efficient design to architecture students. Second, the local water service provider was given a new tool for future commercial building owner compliance in the case of a Level 2 Drought declaration. Third, the water audit provided the building owner with cost- effective strategies to accomplish use reduction. Finally, the architectural professional community received a new tool for water efficient design and retrofit. The paper presents a tool for architecture students and professionals to expand integrated water efficient design for commercial buildings.

description: The University of Arizona’s architectural education program utilizes the dual learning vehicles of design-build pedagogy and affordable housing projects to investigate the cost effectiveness of regional vernacular construction methods paired with contemporary energy and water conservation strategies to control initial construction costs and long-term operational costs of single-family dwellings.

Earth, clay and stone, indigenous building materials with long histories in the arid deserts of the southwestern U.S., have diminished in use as labor prices have risen in the construction industry. Over the course of six design-build projects, Building Technology faculty and students experimented with and improved wall forming systems for rammed earth and pumice-crete, in order to reduce labor costs and bring these vernacular materials into use for affordable housing. The focus of the applied field research was the design of the wall forms and the sequence of building multiple walls with bond beams. Students built full scale wall mock-ups, created budget and energy models, tackled critical path construction scheduling, and interacted with subcontractors, inspectors, and building permit officials during design and construction of the housing units.

Our methods of earthen wall construction were refined over three main iterations and six projects, resulting in streamlined procedures, reduced construction time, and costs that were much lower than similar commercially built systems. The value of the design-build and research processes for students goes beyond exposure to the entire spectrum of housing design; the iterative investigations of wall forming systems across multiple projects teaches the value of Building Technology research and discovery through architectural practice.

description: Nature has inspired architecture for millennia and recent discoveries allow designers to understand the wealth of biological information further. The architectural profession is at a critical point in history with regards to reducing its impact on the environment. To truly minimize a building’s impact it needs to interact more holistically with its surroundings. The lessons learned from natural systems can be applied to architecture to lessen its environmental impact, and this is a critical point to ask: Will architects utilize construction technology as well as advanced scientific knowledge to create an architecture that behaves like nature? Imagine a building that can convert carbon dioxide to oxygen and during the process efficiently converting sunlight into energy.

The Architecture + Biomimicry course was set up so students could specifically address this question and explore these possibilities. Research of literature and experts helped the students seek an answer to ‘What would nature do?’ This knowledge was then applied to an architectural solution that addressed the original challenge they selected. Work culminated in an exhibit and was attended by numerous faculty and students from cross-disciplinary fields (including engineering, interior design and sustainability). Discussions with these professors planted the seed for this course to expand and coordinate with their courses. This will lead to a new interdisciplinary approach to seeing and solving challenges in a new light.

Students will learn to look beyond the forms in nature and understand the principles behind them in order to create effective solutions to environmental issues; for example carbon dioxide emissions. Which will require the construction industry to look beyond itself and look to nature with its array of plentiful, creative appropriate designs. Since buildings account for thirty-nine percent of carbon dioxide emissions in the United States, these designs provide crucial for architects to learn from.

description: The capability to tune the strength of the elastic interparticle interaction is crucial for many experiments with ultracold gases. Magnetic Feshbach resonances are a tool widely used for this purpose, but future experiments would benefit from additional flexibility such as spatial modulation of the interaction strength on short length scales. Optical Feshbach resonances offer this possibility in principle, but suffer from fast particle loss due to light-induced inelastic collisions. Here we show that light near-resonant with a molecular bound-to-bound transition can be used to shift the magnetic field at which a magnetic Feshbach resonance occurs. This makes it possible to tune the interaction strength with laser light and at the same time induce considerably less loss than an optical Feshbach resonance would do.
On consistency and null sets in Bayes estimation

description: A basic result of Doob states that, under very weak measurability assumptions, Bayes’ estimators are consistent for almost all parameter points. First it is shown that even when this exceptional set is finite, the effect of putting positive prior mass on each point of the set may result in creating a new exceptional set, larger than the original one, rather than in eliminating the lack of consistency. The .posterior densities are then studied and it is shown that under fairly strong regularity conditions the corresponding posterior distributions tend, in the limit, to concentrate their mass on a particular point in the parameter set. If in addition, distinct parameter points correspond to distinct probability measures, then it is shown that both the maximum likelihood and the Bayes' estimators are consistent for all parameter values.
title: Trans-Disciplinary Detail in Mass Timber

description: In Towards a New Architecture, Le Corbusier claims that the field of engineering, through its adherence to the noble fields of Economy and Mathematics, has surpassed the field of architecture in the pursuit of harmonious, meaningful structures. He does not suggest that architects partner with engineers; he only implores architects to cop-opt engineers’ ethic to leverage their own field from its current state of “retrogression”. Gaining expertise then obviates collaboration. Following this, Corbusier laments the glacial unfolding of architecture through incremental developments in structure and ornament, finding impetus for his cross-disciplinary foray in the previous five decades of material development, namely the “conquests” of steel and concrete. (9) This passage, titled ‘Architecture or Revolution’ finds resonance today when ‘steel and concrete’ are replaced by ‘mass timber.’

Superficially anachronistic, this return to timber finds its depth not in the invention of the material, but in its reinvention as a medium under the purview of a variety of disciplines, from architecture and engineering to fabrication and materials science. This transdisciplinary thinking has defined mass timber types by their details, i.e., the ways in which they are assembled and joined with other materials. Mass timber is not borne of a fetishization of wood; it is most viable when its use capitalizes on the intrinsic strengths of steel, concrete, and other extant material systems. (Dangel 108) Unlike dimensional, heavy, or linear engineered wood products, mass timber’s morphology operates as a function of its detail. This paper argues that, if mass timber is an assemblage of details and a fundamentally trans-disciplinary material, the details, or detail, itself is an acute source of trans-disciplinary interaction.

An emergent material, mass timber is only entering the adolescent stages of its development. Research and pedagogy surrounding mass timber are best focused on examinations of the intrinsic and extrinsic impacts of its detail. This detail manifests across scales; each scale corresponds to a set of disciplines. The cellular scale finds one in the realm of wood anatomy. Here, detail exists as designed by the growing tree, where the primary program is the express motivation to handle currents flowing through- and along them. (Bejan 130) An anisotropic, cellular solid, wood’s structures and systems at the cellular scale exhibit analogies for mass timber and may provide insight as to how those systems are best assembled. This paper will examine this and a variety of other scales of detail through coursework and exploratory research. Ultimately, it posits methods by which a trans-scalar, trans-disciplinary examination of mass timber’s detail might permit architectural practice, research, and pedagogy that better leverages its latent performance.

description: Pads of beetles are covered with long, deformable setae, each ending in a micrometric terminal plate coated with secretory fluid. It was recently shown that the layer of the pad secretion covering the terminal plates is responsible for the generation of strong attractive forces. However, less is known about the fluid itself because it is produced in extremely small quantity. We here present a first experimental investigation of the rheological properties of the pad secretion in the Colorado potato beetle {\it Leptinotarsa decemlineata}. Because the secretion is produced in an extremely small amount at the level of the terminal plate, we first develop a procedure based on capillary effects to collect the secretion. We then manage to incorporate micrometric beads, initially in the form of a dry powder, and record their thermal motion to determine the mechanical properties of the surrounding medium. We achieve such a quantitative measurement within the collected volume, much smaller than the $1 {\rm μ}$l sample volume usually required for this technique. Surprisingly, the beetle secretion was found to behave as a purely viscous liquid, of high viscosity. This suggests that no specific complex fluid behaviour is needed during beetle locomotion. We build a scenario for the contact formation between the spatula at the setal tip and a substrate, during the insect walk. We show that the attachment dynamics of the insect pad computed from the high measured viscosity is in good agreement with observed insect pace. We finally discuss the consequences of the secretion viscosity on the insect adhesion.

description: Knowledge of building science – how buildings perform with respect to energy efficiency, durability, comfort, and health – is a key aspect of sustainable architectural design. Although most building science courses are taught in a traditional lecture format, experiential teaching methods have the potential to improve student engagement and comprehension of technical subject matter.

This paper describes a case study of experiential learning in building science education. In Spring, 2018, we conducted a thermal comfort study as part of an integrated design studio at Pratt Institute in Brooklyn, NY. We measured temperature and relative humidity in the studio space and asked students about their thermal comfort via daily, point-in-time surveys.

We analyzed the sensor results using the PMV model, finding that the majority of the studio (87% of sensor locations) was within the comfort zone (PMV between -0.5 and +0.5) during the study period. Students’ average reported thermal sensation over the same period (AMV, or actual mean vote) was -0.46, a result that suggested cold discomfort. The discrepancy between PMV and AMV suggests that factors not measured in this study – such as mean radiant temperature or air speed – may have negatively impacted students’ comfort.

This case study suggests the potential for integrating hands-on building science investigations into technical architecture courses. Areas for improvement include tighter integration of these investigations into individual courses and the broader architecture curriculum to achieve the greatest impact on student engagement and learning
