description: WASP-127b is one of the puffiest exoplanets found to date, with a mass only $3.4$ Neptune masses, but a radius larger than Jupiter. It is also located at the border of the Neptune desert, which describes the lack of highly-irradiated Neptune-sized planets, and which remains poorly understood. Its large scale height and bright host star make the transiting WASP-127b a valuable target to characterise in transmission spectroscopy. We use combined EulerCam and TESS light curves to recalculate the system's parameters. Additionally, we present an in-depth search for sodium in four transit observations of WASP-127b, obtained as part of the Hot Exoplanet Atmosphere Resolved with Transit Spectroscopy (HEARTS) survey with the High Accuracy Radial velocity Planet Searcher (HARPS) spectrograph. Two nights from this dataset were analysed independently by another team, claiming a detection of sodium incompatible with previous studies of data from both ground and space. We show that this large sodium detection is actually due to contamination from telluric sodium emissions and the low S/N in the core of the deep stellar sodium lines. When properly accounting for these effects, the previous sodium signal is reduced to an absorption of $0.46\pm0.20\%$ ($2.3σ$), which is compatible with analyses of WASP-127b transits carried out with other instruments. We can fit a Gaussian to the D2 line, however, the D1 line was not detected, indicating an unusual line ratio if sodium exists in the atmosphere. Follow-up of WASP-127 at both high-resolution and with high sensitivity will be required to firmly establish the presence of sodium and analyse its line shape.

description: The paper deals with cosmology in modified f(T) gravity theory. With some phenomenological choices for the function f(T) it is possible to have cosmological solutions describing different phases of the evolution of the Universe for the homogeneous and isotropic FLRW model. By proper choice of the parameters involved in the function $f(T)$ and also in the cosmological solutions it is shown that a continuous cosmic evolution starting from the emergent scenario to the present late time acceleration is possible. Finally thermodynamical analysis of f(T) gravity is presented.

description: The self-duality equations on a Riemann surface arise as dimensional reduction of self-dual Yang-Mills equations. Hitchin had showed that the moduli space ${\mathcal M}$ of solutions of the self-duality equations on a compact Riemann surface of genus $g >1$ has a hyperKähler structure. In particular ${\mathcal M}$ is a symplectic manifold. In this paper we elaborate on one of the symplectic structures, the details of which is missing in Hitchin's paper. Next we apply Quillen's determinant line bundle construction to show that ${\mathcal M}$ admits a prequantum line bundle. The Quillen curvature is shown to be proportional to the symplectic form mentioned above. We do it in two ways, one of them is a bit unnatural (published in R.O.M.P.) and a second way which is more natural.

On small-scale and large-scale intermittency of Lagrangian statistics in canopy flow

Year: 2020
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The interaction of fluids with surface-mounted obstacles in canopy flows leads to strong turbulence that dominates dispersion and mixing in the neutrally stable atmospheric surface layer. This work focuses on intermittency in the Lagrangian velocity statistics in a canopy flow, which is observed in two distinct forms. The first, small scale intermittency, is expressed by non-Gaussian and not self-similar statistics of the velocity increments. The analysis shows an agreement in comparison with previous results from homogeneous isotropic turbulence (HIT) using the multifractal model, extended self-similarity, and acceleration autocorrelations. These observations suggest that the picture of small-scale Lagrangian intermittency in canopy flows is similar to that in HIT, and therefore, they extend the idea of universal Lagrangian intermittency to certain inhomogeneous and anisotropic flows. Second, it is observed that the RMS of energy increments along Lagrangian trajectories depend on the direction of the trajectories' time-averaged turbulent velocity. Subsequent analysis suggests that the flow is attenuated by the canopy drag while leaving the structure function's scaling unchanged. This observation implies the existence of large-scale intermittency in Lagrangian statistics. Thus, this work presents a first empirical evidence of intermittent Lagrangian velocity statistics in a canopy flow that exists in two distinct senses and occurs due to different mechanisms.

description: Fixed points in three dimensions described by conformal field theories with $MN_{m,n}= O(m)^n\rtimes S_n$ global symmetry have extensive applications in critical phenomena. Associated experimental data for $m=n=2$ suggest the existence of two non-trivial fixed points, while the $\varepsilon$ expansion predicts only one, resulting in a puzzling state of affairs. A recent numerical conformal bootstrap study has found two kinks for small values of the parameters $m$ and $n$, with critical exponents in good agreement with experimental determinations in the $m=n=2$ case. In this paper we investigate the fate of the corresponding fixed points as we vary the parameters $m$ and $n$. We find that one family of kinks approaches a perturbative limit as $m$ increases, and using large spin perturbation theory we construct a large $m$ expansion that fits well with the numerical data. This new expansion, akin to the large $N$ expansion of critical $O(N)$ models, is compatible with the fixed point found in the $\varepsilon$ expansion. For the other family of kinks, we find that it persists only for $n=2$, where for large $m$ it approaches a non-perturbative limit with $Δ_ϕ\approx 0.75$. We investigate the spectrum in the case $MN_{100,2}$ and find consistency with expectations from the lightcone bootstrap.

description: The propagation of cosmological ionization fronts (I-fronts) during reionization is strongly influenced by small-scale structure. Here we summarize our recent attemps to understand the effect of this small-scale structure. We present high resolution cosmological N-body simulations at high-z (z>6) which resolve a wide range of halo mass, from minihalos to clusters of large, rare halos. We also study how minihalos affect I-fronts, through simulations of minihalo photoevaporation. Furthermore, we modify the I-front propagation equations to account for evolving small-scale structure, and incorporate these results into a semi-analytical reionization model. When intergalactic medium clumping and minihalo clustering around sources are included, small-scale structure affects reionization by slowing it down and extending it in time. This helps to explain observations by the Wilkinson Microwave Anisotropy Probe, which imply an early and extended reionization epoch. We also study how source clustering affects the evolution and size of H II regions, finding, in agreement with simulations, that H II regions usually expand, rarely shrinking. Hence, "relic H II regions'' are an exception, rather than the rule. When the suppression of small-mass sources in already-ionized regions by Jeans-mass filtering is accounted for, H II regions are smaller, delaying overlap. We also present a new numerical method for radiative transfer which is fast, efficient, and easily coupled to hydrodynamics and N-body codes, along with sample tests and applications.

Recombination-independent determination of the sound horizon and the Hubble constant from BAO

description: The Hubble tension and attempts to resolve it by modifying the physics of (or at) recombination motivate finding ways to determine $H_0$ and the sound horizon at the epoch of baryon decoupling $r_{\rm d}$ in ways that neither rely on a recombination model nor on late-time Hubble data. In this work, we investigate what one can learn from the current and future BAO data when treating $r_{\rm d}$ and $H_0$ as independent free parameters. It is well known that BAO gives exquisite constraints on the product $r_{\rm d}H_0$. We show here that imposing a moderate prior on $Ω_{\rm m} h^2$ breaks the degeneracy between $r_{\rm d}$ and $H_0$. Using the latest BAO data, including the recently released eBOSS DR16, along with a $Ω_{\rm m} h^2$ prior based on the Planck best fit $Λ$CDM model, we find $r_{\rm d} =143.7 \pm 2.7$ Mpc and $H_0 = 69.6 \pm 1.8$ km/s/Mpc. BAO data therefore prefers somewhat lower $r_{\rm d}$ and higher $H_0$ than those inferred from Planck data in a $Λ$CDM model. We find similar values when combing BAO with the Pantheon supernovae, DES galaxy weak lensing, Planck or SPTPol CMB lensing and the cosmic chronometers data. We perform a forecast for DESI and find that, when aided with a moderate prior on $Ω_{\rm m} h^2$, DESI will measure $r_{\rm d}$ and $H_0$ without assuming a recombination model with an accuracy surpassing the current best estimates from Planck.

Power, curriculum making and actor-network theory : the case of physics, technology and society curriculum in Bahrain
Creators: name: Rafea, Ahmed Mohammed
Publisher: name: University of British Columbia
Year: 2009

description: This study is an exploration of power and how it is manifested in curriculum making. More specifically, it examines the responses of actors in the physics curriculum network to a proposal to introduce a Physics, Technology and Society (PTS) version of physics in the secondary schools of Bahrain. The proposal to introduce PTS created a point of entry to explore issues of power in curriculum making and highlight some of the strategies that actors used to maintain or reconstruct power relations. Data collection consisted of three phases during which interviews were conducted with Ministry of Education personnel, university physicists and physics educators, physics teachers, university and secondary students, and industry representatives. Interviews focused on responses to: 1) an example of PTS materials (Phase One); 2) the views of other actors (Phase Two); and 3) the Ministry's decision to proceed with piloting of the PTS materials (Phase Three). From Actor-Network Theory (ANT), the responses of the various actors can be understood in terms of their efforts to maintain or reconstruct the school physics network. Furthermore, the study shows that curriculum making can be seen as a networking process in which the success of the various actors is linked to the size and strength of the networks they are able to mobilize to their position. From this point of view, the Ministry, drawing primarily on local networks, is seen to move cautiously in response to the extensive international network which university physicists maintain and which provides high status pathways for students. Power relations are network effects, and in exploring them one gains a better appreciation of the network that constructed them. Therefore, this study illuminates aspects of the school physics network, revealing its constituent actors, the strength of the links between some of its actors, and the establishment of the curriculum as an obligatory passage point. Conclusions pertaining to the nature of this network and the strategies employed by actors in constructing and maintaining power relations as they engaged in negotiating the physics curriculum are drawn. Finally, these conclusions have implications for policy in curriculum change and, more specifically, for addressing issues of power and problems that emerge when fundamental changes in secondary science are introduced.

description: A quantum Langevin model, similar to models used recently for optomechanics, was used to predict intermodulation phonon sidebands (IPS). Ab initio calculations of anharmonic phonons in rocksalt NaBr showed these spectral features as "many-body effects". Modern inelastic neutron scattering measurements on a crystal of NaBr at 300K revealed diffuse intensity at high phonon energy from a predicted upper IPS. The transverse optical (TO) part of the new features originates from phonon intermodulation between the transverse acoustic (TA) and TO phonons. The longitudinal optical (LO) spectral features originate from three-phonon coupling between the TA modes and the TO lattice modes. The partner lower IPS proves to be an "intrinsic localized mode". Interactions with the thermal bath broaden and redistribute the spectral weight of the IPS pair. These sidebands are a probe of anharmonicity and quantum noise, which originate from interactions between the phonons in NaBr.
Black Hole Formation from Collapsing Dust Fluid in a Background of Dark Energy

description: The gravitational collapse of a spherically symmetric star, made of a dust fluid, $ρ_{DM}$, in a background of dark energy, $p = wρ,\; (w < -1/3)$, is studied. It is found that when only dark energy is present, black holes are {\em never} formed. When both of them are present, black holes can be formed, due to the condensation of the dust fluid. Initially the dust fluid may not play an important role, but, as time increases, it will dominate the collapse and finally leads to formation of black holes. This result remains true even when the interaction between the dust fluid and dark energy does not vanish. When $w < -1$ (phantoms), some models can also be interpreted as representing the death of a white hole that ejects both dust and phantoms. The ejected matter re-collapses to form a black hole.

Exteriority and deconstruction : against counterfeit nineteenth century European ideas on music education
Creators: name: Imada, Tadahiko
Publisher: name: University of British Columbia
Year: 2009

description: The modem and contenporary history of Western music education has focused on interpreting musical value based on the principles derived from the "aesthetic experience" of nineteenth century metaphysics. Traditional Western aesthetics based on Platonic ethos and Aristotelian mimesis has also exerted a great influence on Japsuiese music education. However, the Japanese nineteenth century differed fundamentally from the nineteenth century of the West. The concept of "man" or "meaning" in nineteenth century Europe was absent from Japan (e.g., Karatani, 1989). The French post-structuralists state that Western people in the twentieth century are still the prisoner of a determined system of the nineteenth century bourgeois-humanist. These a£fect all aspects of life. Thus attention should be paid to invisible powers supporting a spurious unified approach in today's music education curriculum. The twentieth century has seen the emergence of many thinkers such as Derrida and Foucault who criticize Western metaphysics. Their criticism reveals a power structure expressed in the concefjt of logocentrism that tends to unify and centralize. EuropeeUi music's autonomy and hegemony has been believed and taken £or granted for at least a century (Said, 1991). Kany music teachers in Japan have blind faith in Western aesthetics. Today there is an tirgent need to bring contemporary discourse and the concept of exteriority to the analysis of Japanese music education. This thesis attenpts to contribute to that discourse.

By introducing simple CP-violating phases in the mass matrix of the right-handed neutrinos, the model generates sufficient baryon asymmetry without fine-tuning. We compare this result with other realistic SO(10) models.

Contrary to previously proposed models, the system is best described as an asymmetric quantum spin ladder. The observed spectrum is interpreted in terms of ``composite'' Haldane spin chains. The key difference from actual S=1 chains is a sharp cutoff of the single-magnon spectrum at a certain critical wave vector.

description: In this paper, we demonstrate a pulse energy-governed nonlinear self-switching of femtosecond pulses at wavelength of 1700 nm in a highly nonlinear high index contrast dual-core fibre. The fibre structure is composed of two microdimension cores and a solid cladding made of two thermally matched soft glasses developed in-house. A double switching behaviour under monotonic increase of the input pulse energy from 1 nJ to 3 nJ was observed at 35 mm fibre length in its anomalous dispersion region. A spatial intensity distribution measurement identified a switching contrast of 16.7 dB, and the registered spectra of the two output channels revealed a broadband switching behaviour within 150 nm. The obtained results indicate a novel type of solitonic switching and represent a significant progress in comparison to the previous experimental works and has a high application potential.

description: Tuning thermal transport in semiconductor nanostructures is of great significance for thermal management in information and power electronics. With excellent transport properties, such as ballistic transport, immunity to point defects and disorders, and forbidden backscattering, topological phonon surface states show remarkable potential in addressing this issue. Herein, topological phonon analyses are performed on hexagonal wurtzite GaN to check the topological characteristics of phonons. And other nitrides of the same family, i.e., AlN and AlGaN alloy, are also calculated from a topological phonon phase transition perspective. With the aid of first-principle calculations and topological phonon theory, Weyl phonon states, which host surfaces states without backscattering, are investigated for all these materials. The results show that there is no nontrivial topological phonon state in GaN. However, by introducing Al atoms, i.e., in wurtzite type AlN and AlGaN, more than one Weyl phonon point is found, confirmed by obvious topological characteristics, including non-zero integer topological charges, source/sink in Berry curvature distributions, surface local density of states and surface arcs. As AlN and AlGaN are typical materials in AlGaN/GaN heterostructure based electronics, the existence of topological phonon states in them will benefit thermal management by facilitating the design of one-way interfacial phonon transport without backscattering.

description: Let $(X,Y)$ be a random variable consisting of an observed feature vector $X\in \mathcal{X}$ and an unobserved class label $Y\in \{1,2,...,L\}$ with unknown joint distribution. In addition, let $\mathcal{D}$ be a training data set consisting of $n$ completely observed independent copies of $(X,Y)$. Usual classification procedures provide point predictors (classifiers) $\widehat{Y}(X,\mathcal{D})$ of $Y$ or estimate the conditional distribution of $Y$ given $X$. In order to quantify the certainty of classifying $X$ we propose to construct for each $θ=1,2,...,L$ a p-value $π_θ(X,\mathcal{D})$ for the null hypothesis that $Y=θ$, treating $Y$ temporarily as a fixed parameter. In other words, the point predictor $\widehat{Y}(X,\mathcal{D})$ is replaced with a prediction region for $Y$ with a certain confidence. We argue that (i) this approach is advantageous over traditional approaches and (ii) any reasonable classifier can be modified to yield nonparametric p-values. We discuss issues such as optimality, single use and multiple use validity, as well as computational and graphical aspects.

description: Blackbody radiation (BBR) sources are calculable radiation sources that are frequently used in radiometry, temperature dissemination, and remote sensing. Despite their ubiquity, blackbody sources and radiometers have a plethora of systematics. We envision a new, primary route to measuring blackbody radiation using ensembles of polarizable quantum systems, such as Rydberg atoms and diatomic molecules. Quantum measurements with these exquisite electric field sensors could enable active feedback, improved design, and, ultimately, lower radiometric and thermal uncertainties of blackbody standards. A portable, calibration-free Rydberg-atom physics package could also complement a variety of classical radiation detector and thermometers. The successful merger of quantum and blackbody-based measurements provides a new, fundamental paradigm for blackbody physics.

description: This thesis presents studies conducted to elucidate structural features of substrates and inhibitors of the enzyme peptidylglycine alpha-amidating monooxygenase (PAM) that may be important for drug design. Given the focus on applicability to drug design, studies focussed on subtypes of PAM from human cancer cell lines. Chapter 1 of this Thesis describes the development of a cultured cell assay suitable for monitoring PAM activity from human carcinomas and quantifying enzyme inhibition. These studies identified sources of human PAM and lead to the later development by another member of the Easton group of another, more sensitive, cultured cell assay. Having identified cellular sources of PAM, cellular and secreted enzyme subtypes were extracted from two vastly different cancer cell lines for use in further PAM studies. A range of PAM substrate and inhibitor peptidomimetic analogues of the prohormone of thyrotropin releasing hormone as well as prooxytocin were synthesised and assayed with two enzyme subtypes. These studies demonstrated that the potency of both substrates and inhibitors can be increased through substitution of a penultimate amino acid with phenylalanine and that such alteration of peptidomimetic glycolate inhibitors results in a loss of specificity for cellular enzyme. These studies also demonstrated that PAM recognises peptide sequences and that this sequence recognition extends beyond four amino acids from the C terminus. Potent inhibitors with binding affinities for PAM in the low micromolar range were developed. The N-terminal amide of the penultimate residue was shown, using assays with cellular and secreted subtypes from two enzymes, to decrease inhibitor potency. It also eliminates specificity, probably as a result of forcing inhibitors to adopt an alternative binding mode. Conversely, it was found that substitution of the N-terminal nitrogen of a penultimate residue with a polar substituent resulted in improved binding to PAM. Indeed the improvement in binding affinity resulting from substitution at the amide nitrogen was found to be greater than analogous substitution at the alpha- position. Such substitution did however result in a loss of specificity. An olefinic fatty acid was shown to be a potent and selective inhibitor of PAM from two cell lines. This inhibitor had a binding affinity in the low micromolar range.

description: We study the topological B-model on a deformed $\Z_2$ orbifolded conifold by investigating variation of complex structures via quantum Kodaira-Spencer theories. The fermionic/brane formulation together with systematic utilization of symmetries of the geometry gives rise to a free fermion realization of the amplitudes. We derive Ward identities which solve the perturbed free energy exactly. We also obtain the corresponding Kontsevich-like matrix model. All these confirm the recent conjecture on the connection of the theory with ${\hat c}=1$ type 0A string theory compactified at the radius $R=\sqrt{α'/2}$.

description: We report the results of the pressure-dependent measurements of the static magnetization and of the ferromagnetic resonance (FMR) of Cr$_2$Ge$_2$Te$_6$ to address the properties of the ferromagnetic phase of this quasi-two-dimensional van der Waals magnet. The static magnetic data at hydrostatic pressures up to 3.4 GPa reveal a gradual suppression of ferromagnetism in terms of a reduction of the critical transition temperature, a broadening of the transition width and an increase of the field necessary to fully saturate the magnetization $M_{\rm s}$. The value of $M_{\rm s} \simeq 3μ_{\rm B}$/Cr remains constant within the error bars up to a pressure of 2.8 GPa. The anisotropy of the FMR signal continuously diminishes in the studied hydrostatic pressure range up to 2.39 GPa suggesting a reduction of the easy-axis type magnetocrystalline anisotropy energy (MAE). A quantitative analysis of the FMR data gives evidence that up to this pressure the MAE constant $K_{\rm U}$, although getting significantly smaller, still remains finite and positive, i.e. of the easy-axis type. Therefore, a recently discussed possibility of switching the sign of the magnetocrystalline anisotropy in Cr$_2$Ge$_2$Te$_6$ could only be expected at still higher pressures, if possible at all due to the observed weakening of the ferromagnetism under pressure. This circumstance may be of relevance for the design of strain-engineered functional heterostructures containing layers of Cr$_2$Ge$_2$Te$_6$.
A cosmopolitan right of necessity

description: Confronted with the high toll of human lives that global poverty takes today, and the widening gap between the rich and the poor, a growing number of contemporary moral theorists and political philosophers have posed the question of what moral duties wealthy countries and individuals owe to the poor. Their answers could be divided in two main camps. Justice cosmopolitans, on one hand, emphasize the importance of building just institutions at the global level that stop harming the worse-off. On the other hand, assistance cosmopolitans emphasize the importance of aiding the needy, regardless of any past or present responsibilities that the wealthy may have toward them. In this thesis I focus on what the needy may do for themselves in order to get out of their plight. I believe this is a necessary complement to the perspective where the materially privileged seem also to be the morally anointed to address the plight of the needy. My claim is that, given certain conditions - i.e. the agent is morally innocent, the resources are accessible, the owner is not equally (or nearly as) needy in the same relevant respect, and it is a last resort - an agent in need has a right to take and use any resources needed to survive. This right has the form of a claim over those resources; that is, a right which is correlated with a duty on their owner to give them away or to let them be taken and used by the needy - if the owner is present and aware of the relevant circumstances. If he is absent, meanwhile, the agent may take and use those resources, assuming that - had the owner been present - he would have recognized her right. Moreover, this right is morally enforceable, by which I mean that the agent may take and use the resources needed by actual force if the owner fails to comply with his correlative duty, even if this goes against the established laws and social mores. I develop the normative framework of this cosmopolitan right of necessity and its correlative duty of humanity (as I call them in continuity with a long-standing philosophical tradition), based on the accounts of Samuel Pufendorf and Francis Hutcheson. Because they give different justifications for this moral relation (the former, contractarian-based; the latter, utilitarian), my aim is to persuade readers of both leanings that it is not contradictory, but follows from the very principles of these theories to accept the existence of such a duty and right. I then refer to the implications of accepting this principle as part of a cosmopolitan morality, and present some contemporary scenarios where it may be applied. -- provided by Candidate.

JAN-OLAN HENRIKSEN, Finitude and theological anthropology. An interdisciplinary exploration into theological dimensions of finitude
Creators: name: Limone, Raffaella
Publisher: name: Nuovo Giornale di Filosofia della Religione
Year: 2021

description: Il tema della finitezza si contraddistingue perché non concerne unicamente la dimensione antropologica della religione, ma coinvolge un orizzonte disciplinare piuttosto ampio. Infatti parlare di finitudine significa principalmente riflettere sulla condizione umana, non solo in relazione al divino, ma anche in relazione alle miriadi di esperienze umane che definiscono la contingenza e limitatezza dell’umano. Si tratta dunque di un tema che forse ci porta a chiederci in che termini nel mondo contemporaneo si possa parlare di Dio, del peccato e di altri analoghi motivi significativi per la religione.

description: The Landau levels of cold atomic gases in non-Abelian gauge fields are analyzed. In particular we identify effects on the energy spectrum and density distribution which are purely due to the non-Abelian character of the fields. We investigate in detail non-Abelian generalizations of both the Landau and the symmetric gauge. Finally, we discuss how these non-Abelian Landau and symmetric gauges may be generated by means of realistically feasible lasers in a tripod scheme.

Hanging Emily : exhibition strategies and Emily Carr
Creators: name: Knutson, Karen Leslie
Publisher: name: University of British Columbia
Year: 2009

description: This study examines the impact of new museological theory on museum education practice at the Vancouver Art Gallery in relation to a re-installation of Emily Carr's work. It is a case study that concerns both the negotiation of meanings around Emily Carr's work as they are situated within current and traditional art historical/ historical beliefs, and the desire to offer museum visitors a more sufficient or comprehensive educational experience. The dissertation examines the installation of Carr in a variety of galleries across Canada (National Gallery, Art Gallery of Ontario, Art Gallery of Greater Victoria, Vancouver Art Gallery) as a means of contextualizing a range of problems associated with museum practice. The National Gallery chapter explores issues of ideology raised by the new museology. The chapter concerning the display at the Art Gallery of Greater Victoria concerns the particularities of site and place (Victoria was Carr's birthplace) as well as notions of resonance and contextualization in art displays. The discussion of the Art Gallery of Ontario concerns contextualization of a different sort, the display created with a solid foundation in educational literature. A temporary exhibition of Carr's work juxtaposed with that of Lawrence Paul Yuxweluptun in Vancouver offers an entry point into a discussion of subjectivity and curatorial epistemic authority, while the resulting re-installation of Carr at the Vancouver Art Gallery (the case) is explored as one possible approach to issues raised in the earlier chapters, by the challenges of post-modem theorists to historical understanding, historiography, and museum practice.
A DINÂMICA DE PREÇOS NO MERCADO DE IMÓVEIS RESIDENCIAS : Análise do Município de São Paulo

description: Com este trabalho deseja-se identificar os fatores que influenciam o mercado habitacional, assim como os elementos que compõem o preço da moradia ofertado pela Indústria Imobiliária. Este estudo trata-se de uma análise da dinâmica dos preços no Mercado Imobiliário de São Paulo no período entre 2007 a 2014. Após a Crise Financeira de 2008, economistas que previram a bolha americana, como Robert Shiller, argumentaram uma possível irracionalidade no preço do imóvel do Brasil, sendo descrito por alguns como Bolha Imobiliária. Conceitualmente, atribuiu-se bolha imobiliária como uma má precificação dos imóveis, isto é, quando ocorre um descolamento entre o preço de mercado e o valor justo da moradia. Esta ideia iniciase quando os agentes econômicos estão comprando imóveis apenas com o viés de retorno financeiro, em que eles especulam a fim de adquirir um valor de venda superior ao comercializado. Portando, cria-se a hipótese do mercado imobiliário do município de São Paulo sendo influenciado por variáveis tanto macroeconômicas como microeconômicas. Citam-se mudanças regionais que infringiram nos custos de produção; aumento da pressão habitacional via crescimento da renda, melhor adequação do crédito à população. Fatores como estes podem traduzir o valor ofertado do imóvel no período de 2007 a 2014.
