description: This essay shows the importance of placing Occupy Wall Street (OWS) in a global context of preceding social movements protesting against oppressive conditions from certain social groups. In particular, it suggests the opportunity that OWS has for thinking on and learning from Latin-American contestation and political projects against neoliberalism and in struggle for the rights of latina/os and immigrants in the United States. While in some Latin-American cases public protests, and in particular the occupation of public spaces, have helped in the election of political representatives who support popular agendas, in the case of recent pro-immigrant struggles in the United States the public demonstrations have been followed by a repressive governmental reaction that has seriously worsened both the conditions of non-authorized immigrants and the capacities of the movement that supports them. The article argues that, as in these precedents, OWS could result in the election of politicians that recognize the demands of the movement, or, on the contrary, reinforce the devices of control and repression against public disagreement.

"Y'all come and have fun": discovering a New Jersey country and western music scene in a box of postcards
Creators: name: Lutz, Christine A.
Publisher: name: No Publisher Supplied
Year: 2020

description: Several years ago, Rutgers University's Special Collections and University Archives was given a checkbox containing fifty-six postcards advertising country and western music shows at venues around New Jersey. The postcards, primarily from the 1960s, promoted shows featuring Grand Ole Opry stars like Wanda Jackson, Hank Thompson, and Elton Britt. Preliminary research revealed that the postcards touted performances by regional and local musicians, as well. A closer look at the cards began to expose how a small, hyper-local ephemeral collection could bring to light and contribute to a larger history; in this case, a once thriving but little explored New Jersey country and western music scene. The research that forms this article focuses on one venue, the Copa Club in the city of Secaucus, and its owners, brothers and musicians Shorty and Smokey Warren, as a specific case study. This collection of postcards, like so much ephemeral material in archives, could have remained undervalued and under-researched. In this case, a close consideration set forth a journey that included research in local archives and interviews with scene participants. As a result, this article explores the past of an important musical genre that evolved along with social changes in the United States. This piece contributes to the scholarship around uses and value of ephemera, as well as scholarship that continues to challenge the southern origin story of country music and examine vital locales of country music outside the South.

description: This report offers new information about employee counts and sales of the National Establishment Time Series (NETS) Database—which provides time-series data on establishments across all sectors, including grocery stores and food service outlets. It also compares NETS’s employment count to the U.S. Bureau of the Census’s County Business Pattern (CBP) at the national and State levels from 1998 to 2016 and compares NETS’s sales to ERS’s Food Expenditure Series (FES) at the national level from 1998 to 2019. Furthermore, this report re-estimates NETS’s sales numbers, enabling researchers to more accurately study food sales at a more localized level.
Diagnosing celiac disease by video capsule endoscopy (VCE) when esophogastroduodenoscopy (EGD) and biopsy is unable to provide a diagnosis: a case series

description: Video capsule endoscopy (VCE) is mainly used to evaluate patients with celiac disease in whom their course after diagnosis has been unfavorable and the diagnosis of adenocarcinoma, lymphoma or refractory celiac disease is entertained, but it has been suggested that VCE could replace esophagogastroduodenoscopy (EGD) and biopsy under certain circumstances. We report a single center case series of 8 patients with suspected celiac disease who were diagnosed by VCE. EGD and biopsy had been performed in 4 patients resulting in a negative biopsy, declined by 2, and contraindicated in 2 due to hemophilia and von Willebrand disease. In all patients, mucosal changes of scalloping, mucosal mosaicism and reduced folds were seen in either the duodenum or jejunum on VCE. Follow-up in 7 patients demonstrated improvement in either their serological abnormalities or their presenting clinical features on a gluten-free diet. Our case series demonstrates that VCE and the visualization of the characteristic mucosal changes of villous atrophy may replace biopsy as the mode of diagnosis when EGD is either declined or contraindicated, or when duodenal biopsies are negative and there remains a high index of suspicion. Further study is needed to clarify the role and cost of diagnosing celiac disease with VCE.
A hybrid MPM-CFD model for simulating earthquake-induced submarine landslides
Creators: name: Tran, Quoc Anh
Publisher: name: Zenodo
Year: 2023

description: The purpose of this abstract is to describe a coupled CFD-MPM model that combines soil mechanics (saturated sediments) with fluid mechanics (seawater or air) as well as solid mechanics (structures) to consider interactions between soil, fluid, and structures. With this formulation, the Material Point Method, which models large deformations in porous media and structures in conjunction with the Implicit Continuous-fluid Eulerian Method, which models complex fluid flows, is combined to model large deformations in porous media and structures. The model has been validated through various benchmarks and then it is used to simulate submarine landslides due to earthquakes. It is shown that this model captures the complicated interactions between saturated sediment, seawater, and offshore structures. This allows us to estimate the impact of potential submarine landslides on offshore structures using the model.
Implementation of sub-nanoseconds TDC in FPGA: applications to time-of-flight analysis in muon radiography

description: Time-of-flight (tof) techniques are standard techniques in high energy physics to determine particles propagation directions. Since particles velocities are generally close to c, the speed of light, and detectors typical dimensions at the meter level, the state-of-the-art tof techniques should reach sub-nanosecond timing resolution. Among the various techniques already available, the recently developed ring oscillator TDC ones, implemented in low cost FPGA, feature a very interesting figure of merit since a very good timing performance may be achieved with limited processing ressources. This issue is relevant for applications where unmanned sensors should have the lowest possible power consumption. Actually this article describes in details the application of this kind of tof technique to muon tomography of geological bodies. Muon tomography aims at measuring density variations and absolute densities through the detection of atmospheric muons flux's attenuation, due to the presence of matter. When the measured fluxes become very low, an identified source of noise comes from backwards propagating particles hitting the detector in a direction pointing to the geological body. The separation between through-going and backward-going particles, on the basis of the tof information is therefore a key parameter for the tomography analysis and subsequent previsions.
Neuroacanthocytosis in China: A Review of Published Reports

description: Background: Neuroacanthocytosis (NA) syndromes are a group of rare diseases characterized by the presence of acanthocytes and neuronal multisystem pathology, including chorea-acanthocytosis (ChAc), McLeod syndrome (MLS), Huntington's disease-like 2 (HDL-2), and pantothenate kinase-associated neurodegeneration (PKAN). China has the largest population in the world, which makes it a good location for investigating rare diseases like NA.

Methods: We searched Medline, ISI Proceedings, China National Knowledge Infrastructure, and Wanfang Data for literature published through December 31, 2013 for all the published Chinese NA case reports and extracted the clinical and laboratory findings.
Results: A total of 42 studies describing 66 cases were found to be eligible for inclusion. Age of symptom onset ranged from 5 to 74 years. The most common findings included hyperkinetic movements (88%), orofacial dyskinesia (80%), dystonia (67%), and dysarthria (68%), as well as caudate atrophy or enlarged lateral ventricles on neuroimaging (64%), and elevated creatine kinase (52%). Most cases were not confirmed by any specific molecular tests. Only two cases were genetically studied and diagnosed as ChAc or MLS.

Discussion: In view of the prevalence of NA syndromes in other countries, the number of patients in China appears to be underestimated. Chinese NA patients may benefit from the establishment of networks that offer specific diagnoses and care for rare diseases.
Metal-insulator transition at the LaAlO3/SrTiO3 interface revisited: A hybrid functional study

description: We investigate the electronic properties of the LaAlO3/SrTiO3 interface using density functional theory. In contrast to previous studies, which relied on (semi-)local functionals and the GGA+U method, we here use a recently developed hybrid functional to determine the electronic structure. This approach offers the distinct advantage of accessing both the metallic and insulating multilayers on a parameter-free equal footing. As compared to calculations based on semilocal GGA functionals, our hybrid functional calculations lead to a considerably increased band gap for the insulating systems. The details of the electronic structure show substantial deviations from those obtained by GGA calculations. This casts severe doubts on all previous results based on semilocal functionals. In particular, corrections using rigid band shifts ("scissors operator") cannot lead to valid results.

description: Polychlorinated biphenyls (PCBs), known endocrine disruptors, were banned in 1979 but persist in the environment. Previous studies are inconsistent regarding prenatal exposure to PCBs and pregnancy outcomes. We investigated associations between prenatal exposure to PCBs and gestational length and birth weight. In a sample of 600 infants (born between 1960 and 1963) randomly selected from Child Health and Development Studies participants followed through adolescence we measured 11 PCB congeners in maternal post partum sera (within three days of delivery). Length of gestation was computed from the reported first day of the last menstrual period (LMP) and delivery date. Linear regression was used to estimate associations between PCB exposure and gestational age and birth weight, adjusting for potential confounders. PCBs were grouped according to hypothesized biological action (1b (sum of weak phenobarbital inducers), 2b (sum of limited dioxin activity), and 3 (sum of CYP1A and CYP2b inducers)) or degree of ortho- substitution (mono, di, tri). Secondary analyses examined associations between total PCB exposure and exposure to individual congeners. Each unit increase in mono-ortho substituted PCBs was associated with a 0.30 week decrease (95% confidence interval (CI) -0.59, -0.016), corresponding to a 2.1 (95% CI −4.13, -0.11) day decrease in length of gestation. Similar associations were estimated for di-ortho substituted PCBs, (1.4 day decrease; (95% CI −2.9, 0.1)) and group 3 PCBs (0.84 day decrease; (95% CI −1.8, 0.11). We found similar associations in congener specific analyses and for the sum of congeners. Our study provides new evidence that PCB exposure shortens length of gestation in humans. This may have public health implications for population exposures.
The gravitational drag force on an extended object moving in a gas

description: Using axisymmetrical numerical simulations, we revisit the gravitational drag felt by a gravitational Plummer sphere with mass M and core radius Rs, moving at constant velocity V0 through a background homogeneous medium of adiabatic gas. Since the potential is non-diverging, there is no gas removal due to accretion. When Rs is larger than the Bondi radius RB, the perturbation is linear at every point and the drag force is well fitted by the time-dependent Ostriker's formula with r_{min}= 2.25Rs, where r_{min} is the minimum impact parameter in the Coulomb logarithm. In the deep nonlinear supersonic regime (Rs<< RB), the minimum radius is no longer related with Rs but with RB. We find r_min=3.3mach^{-2.5}RB, for Mach numbers of the perturber between $1.5$ and $4$, although r_{min} = 2\mach^{-2}RB=2GM/V0^{2} also provides a good fit at mach>2. As a consequence, the drag force does not depend sensitively on the nonlinearity parameter RB/Rs, for RB/Rs-values larger than a certain critical value. We show that our generalized Ostriker's formula for the drag force is more accurate than the formula suggested by Kim & Kim (2009).

description: To use highly resistive material for Kinetic Inductance Detectors (KID), new designs have to be done, in part due to the impedance match needed between the KID chip and the whole 50 ohms readout circuit. Chips from two new hybrid designs, with an aluminum throughline coupled to titanium nitride microresonators, have been measured and compared to a TiN only chip. In the hybrid chips, parasitic temperature dependent box resonances are absent. The dark KID properties have been measured in a large set of resonators. A surprisingly long lifetime, up to 5.6 ms is observed in a few KIDs. For the other more reproducible devices, the mean electrical Noise Equivalent Power is 5.4 10-19 W.Hz1/2.

description: This study was performed to evaluate the attenuation of osteoarthritic (OA) pathogenesis via disruption of the stromal cell-derived factor-1 (SDF-1)/C-X-C chemokine receptor type 4 (CXCR4) signaling with AMD3100 in a guinea pig OA model. OA chondrocytes and cartilage explants were incubated with SDF-1, siRNA CXCR4, or anti-CXCR4 antibody before treatment with SDF-1. Matrix metalloproteases (MMPs) mRNA and protein levels were measured with real-time polymerase chain reaction (RT-PCR) and enzyme-linked immunosorbent assay (ELISA), respectively. The 35 9-month-old male Hartley guinea pigs (0.88 kg ± 0.21 kg) were divided into three groups: AMD-treated group (n = 13); OA group (n = 11); and sham group (n = 11). At 3 months after treatment, knee joints, synovial fluid, and serum were collected for histologic and biochemical analysis. The severity of cartilage damage was assessed by using the modified Mankin score. The levels of SDF-1, glycosaminoglycans (GAGs), MMP-1, MMP-13, and interleukin-1 (IL-1β) were quantified with ELISA. SDF-1 infiltrated cartilage and decreased proteoglycan staining. Increased glycosaminoglycans and MMP-13 activity were found in the culture media in response to SDF-1 treatment. Disrupting the interaction between SDF-1 and CXCR4 with siRNA CXCR4 or CXCR4 antibody attenuated the effect of SDF-1. Safranin-O staining revealed less cartilage damage in the AMD3100-treated animals with the lowest Mankin score compared with the control animals. The levels of SDF-1, GAG, MMP1, MMP-13, and IL-1β were much lower in the synovial fluid of the AMD3100 group than in that of control group. The binding of SDF-1 to CXCR4 induces OA cartilage degeneration. The catabolic processes can be disrupted by pharmacologic blockade of SDF-1/CXCR4 signaling. Together, these findings raise the possibility that disruption of the SDF-1/CXCR4 signaling can be used as a therapeutic approach to attenuate cartilage degeneration.

description: A flow cytometry assay for the glucose transporter SLC2A1/GLUT1 was developed with a genetically-encoded biosensor for measuring free glucose, FLII12Pglu-700md6 (Addgene #17866). This biosensor consists of the E. Coli glucose/galactose-binding protein MglB sandwiched between ECFP and Citrine-YFP. An increase in glucose concentration (dynamic range 0.05 – 11 mM) results in an increased FRET efficiency that can be observed by an increase in Citrine acceptor emission and a decrease in ECFP donor emission.

description: Visual attention plays a fundamental role in avian flight but attention is likely limited whenever birds blink. Because blinks are necessary to maintaining proper vision, this study tested the hypothesis that birds strategically inhibit their blinks in flight. The blinks of captive great-tailed grackles (Quiscalus mexicanus) were recorded before, during and after they flew a short distance in an open environment. The grackles spent the least amount of time blinking in flight (take-off, during flight and landing) and the most amount of time blinking at impact. Their blinking behaviour was similar before and after flight. These results suggest that grackles strategically inhibit their blinking behaviour in flight, potentially because blinks impose costs to avian flight.

description: In the United States (US), Medical Examiners and Coroners (ME/Cs) have the legal authority for the management of mass fatality incidents (MFI). Yet, preparedness and operational capabilities in this sector remain largely unknown. The purpose of this study was twofold; first, to identify appropriate measures of preparedness, and second, to assess preparedness levels and factors significantly associated with preparedness. Three separate checklists were developed to measure different aspects of preparedness: MFI Plan Elements, Operational Capabilities, and Pre-existing Resource Networks. Using a cross-sectional study design, data on these and other variables of interest were collected in 2014 from a national convenience sample of ME/C using an internet-based, anonymous survey. Preparedness levels were determined and compared across Federal Regions and in relation to the number of Presidential Disaster Declarations, also by Federal Region. Bivariate logistic and multivariable models estimated the associations between organizational characteristics and relative preparedness. A large proportion (42%) of respondents reported that less than 25 additional fatalities over a 48-hour period would exceed their response capacities. The preparedness constructs measured three related, yet distinct, aspects of preparedness, with scores highly variable and generally suboptimal. Median scores for the three preparedness measures also varied across Federal Regions and as compared to the number of Presidential Declared Disasters, also by Federal Region. Capacity was especially limited for activating missing persons call centers, launching public communications, especially via social media, and identifying temporary interment sites. The provision of staff training was the only factor studied that was significantly (positively) associated (p

Combining constraints from vacuum stability requirements with these branching ratio measurements we are able to make realistic predictions for the signal strengths in this model. We use these to find a lower bound of 1.3 TeV on the size parameter $R^{-1}$ of the model at 95% confidence level, which is far more stringent than any other reliable bound obtained till now.

Shock attenuation in lattices using phononics
Creators: name: Llumiquinga, Bryan D.
Publisher: name: No Publisher Supplied
Year: 2020

description: Supersonic aircraft deal with turbulent conditions during flight. These turbulent conditions lead to unwanted stresses that often adversely affects the payload. Several lattices were designed to help attenuate any vibrations or shock that may be experienced by the payload through the concept of phononic crystals. Phononic crystals are periodic composite materials designed to control the propagation of mechanical waves using acoustic band gaps. Three different lattice deigns implemented to a cylindrical shell body were initially explored for this study. Combination lattices consisting of two different lattices within the same geometry were also explored. Combination lattices outperformed their single lattice design counterparts, in terms of frequency suppression, due to the fill factor of mechanically contrasting geometries. All lattice cases evaluated experienced a dominant peak in the frequency domain, near the ring frequency of the cylinder. Low frequency cantilevers were successful in trapping some of the energy caused by the ring mode of the structure.

description: To examine substance abuse treatment providers’ views on engaging clients in Pre-exposure Prophylaxis (PrEP) care and research trials. Thirty-six medical and counseling service providers in six New York City outpatient substance abuse treatment programs participated in semi-structured qualitative interviews. Thematic content analysis was conducted by three coders, independently. Providers’ perspectives toward PrEP were characterized by six salient themes: 1) Limited PrEP awareness. 2) Ambivalence about PrEP; 3) Perception of multiple challenges to delivery; 4) Uncertainty about clients’ ability to be adherent to medication; 5) Concerns about medication safety/side effects; and 6) Perception of multiple barriers to conducting clinical trials. Despite anticipated challenges, providers supported the introduction of PrEP in outpatient substance abuse treatment. Comprehensive training for providers is needed and should include PrEP eligibility criteria, strategies to support adherence and medication monitoring guidelines. Linkages between substance abuse treatment and primary care and/or enhancement of capacity within clinics to offer PrEP may help facilitate PrEP delivery. When conducting research in outpatient clinics, it is particularly important to protect client confidentiality.

description: Synaptic dysfunction and loss caused by age-dependent accumulation of synaptotoxic beta amyloid (Abeta) 1–42 oligomers is proposed to underlie cognitive decline in Alzheimer's disease (AD). Alterations in membrane trafficking induced by Abeta oligomers mediates reduction in neuronal surface receptor expression that is the basis for inhibition of electrophysiological measures of synaptic plasticity and thus learning and memory. We have utilized phenotypic screens in mature, in vitro cultures of rat brain cells to identify small molecules which block or prevent the binding and effects of Abeta oligomers. Synthetic Abeta oligomers bind saturably to a single site on neuronal synapses and induce deficits in membrane trafficking in neuronal cultures with an EC50 that corresponds to its binding affinity. The therapeutic lead compounds we have found are pharmacological antagonists of Abeta oligomers, reducing the binding of Abeta oligomers to neurons in vitro, preventing spine loss in neurons and preventing and treating oligomer-induced deficits in membrane trafficking. These molecules are highly brain penetrant and prevent and restore cognitive deficits in mouse models of Alzheimer's disease. Counter-screening these compounds against a broad panel of potential CNS targets revealed they are highly potent and specific ligands of the sigma-2/PGRMC1 receptor. Brain concentrations of the compounds corresponding to greater than 80% receptor occupancy at the sigma-2/PGRMC1 receptor restore cognitive function in transgenic hAPP Swe/Ldn mice. These studies demonstrate that synthetic and human-derived Abeta oligomers act as pharmacologically-behaved ligands at neuronal receptors - i.e. they exhibit saturable binding to a target, they exert a functional effect related to their binding and their displacement by small molecule antagonists blocks their functional effect. The first-in-class small molecule receptor antagonists described here restore memory to normal in multiple AD models and sustain improvement long-term, representing a novel mechanism of action for disease-modifying Alzheimer's therapeutics.

description: The Porto Maravilha Studio represents the work of seven Masters in Urban Planning students from Columbia University Graduate School of Architecture, Planning and Preservation with the guidance of their instructors. In Spring 2012, the studio worked in collaboration with the Municipal Secretary of Housing of Rio de Janeiro (Secretaria Municipal de Habitação, or SMH) to analyze opportunities for incorporating affordable and inclusionary housing in the urban redevelopment plans of Rio de Janeiro’s historic port area. Rio will host a number of mega-events in the next five years, including the 2014 FIFA World Cup and 2016 Summer Olympics Games, and is currently undergoing large-scale urban development projects in preparation for these events. Despite its economic growth, the city faces a growing housing deficit that has been driven by rapidly increasing housing costs and population growth, among other factors. This presents many challenges to the SMH’s goal of ensuring access to housing to low-income residents as a basic social right. In supplementing the SMH’s mission, the Porto Maravilha studio seeks to deliver SMH with planning strategies to
develop both affordable and inclusionary housing through the Porto Maravilha Project, a large urban redevelopment of the port area catalyzed by the upcoming Olympics and other mega-events.

description: The quantitative correlation of the catalytic activity with microscopic structure of heterogeneous catalysts is a major challenge for the field of catalysis science. It requests synergistic capabilities to tailor the structure with atomic scale precision and to control the catalytic reaction to proceed through well-defined pathways. Here we leverage on the controlled growth of MoS2 atomically thin films to demonstrate that the catalytic activity of MoS2 for the hydrogen evolution reaction decreases by a factor of ~4.47 for the addition of every one more layer. Similar layer dependence is also found in edge-riched MoS2 pyramid platelets. This layer-dependent electrocatalysis can be correlated to the hopping of electrons in the vertical direction of MoS2 layers over an interlayer potential barrier, which is found to be 0.119V and consistent with theoretical calculations. Our results point out that increasing the hopping efficiency of electrons in the vertical direction is a key for the development of high-efficiency two-dimensional material catalysts.

Public spaces--Political aspects
Democracy

description: As discussed in the introduction, many scholars have argued that public space is a prerequisite for the expression, representation, preservation and enhancement of democracy (Boudreau, 2000; Caldeira, 2000; Holston and Appadurai, 1999; Low, 2000; Sassen, 1996; Low and Smith, 2006). This has not been more true than in the capital cities of Latin America in recent decades, where political demonstrations have played a critical role in the demise of totalitarian regimes and the reestablishment of democracy. Caracas, capital city of Venezuela, is a prime example in that key urban spaces have been sites for popular demonstrations since Hugo Chavez became President in 1998. Public buildings such as the seats of political and military power, and private ones such as headquarters of media corporations functioned as architectural icons and background to these events.

Ethnoscapes

Publisher: name: Columbia University
Year: 2011
Subjects: City planning

description: Although the urban planning and design literature extensively explores the intersection of race and space, much less work has been done on the study of ethnicity and space, an interrelation I refer to as producting ethnoscapes. This chapter discusses the emergence of ethnoscapes as contemporary spatial typologies, heightened by the new global socio-economic order. The chapter analyzes different processes of ethnicization of space, particularly focusing on Latina/o ethnoscapes in the United States. Latina/os have distinctively used processes of territorializing, regulating, and symbolizing place to sustain distinctive communities flavored by ethnic business and social associations (Arreola 2002; Aguilar San Juan 2005; Irazabal and Gomez-Barris 2007; Irazabal and Farhat 2008). The chapter is composed of four sections. The first three sections discuss critical dimensions of ethnoscapes, spatial and temporal, and political dimensions. The last section discusses emerging challenges and opportunities for urban design and development presented by the increased saliency of ethnicity in the urban world.

Flow cytometry transport assay for SLC2A2 using HEK293 JumpIN TRex SLC2A2 WT-OE cells
Creators: name: Leippe, Philipp
Publisher: name: Zenodo
Year: 2022
Subjects: Transport assay

description: A flow cytometry assay for the glucose transporter SLC2A2/GLUT2 was developed with a genetically-encoded biosensor for measuring free glucose, FLII12Pglu-700md6 (Addgene #17866). This biosensor consists of the E. Coli glucose/galactose-binding protein MglB sandwiched between ECFP and Citrine-YFP. An increase in glucose concentration (dynamic range 0.05 – 11 mM) results in an increased FRET efficiency that can be observed by an increase in Citrine acceptor emission and a decrease in ECFP donor emission.

description: We explore the formation of multipolar structures in planetary and pre-planetary nebulae from the interaction of a fast post-AGB wind with a highly inhomogeneous and filamentary shell structure assumed to form during the final phase of the high density wind. The simulations were performed with a new hydrodynamics code integrated in the interactive framework of the astrophysical modeling package SHAPE. In contrast to conventional astrophysical hydrodynamics software, the new code does not require any programming intervention by the user for setting up or controlling the code. Visualization and analysis of the simulation data has been done in SHAPE without external software. The key conclusion from the simulations is that secondary lobes in planetary nebulae, such as Hubble 5 and K3-17, can be formed through the interaction of a fast low-density wind with a complex high density environment, such as a filamentary circumstellar shell. The more complicated alternative explanation of intermittent collimated outflows that change direction, in many cases may therefore not be necessary. We consider that the wind-shell interaction scenario is more likely since the bow-shock shape expected from a strongly cooling bow-shock from jets is different from that of the observed bubbles. Furthermore, the timescales of the wind-wind interaction suggest that the progenitor star was rather massive.

description: As organizações públicas (neste trabalho também tratadas como governos) estão sujeitas a novas exigências por parte da sociedade. Elas estão relacionadas a uma maior transparência e participação na gestão dos recursos públicos, a um maior controle sobre a qualidade dos serviços prestados, além de uma maior responsabilização por parte de seus gestores sobre a utilização desses recursos. Nesse contexto, a tecnologia da informação e comunicação (TIC) passa a desempenhar um importante papel. Entre os recursos dessa tecnologia, pode-se citar como um dos mais importantes a Internet. A conjunção dos fatores até aqui expostos: maiores exigências da sociedade para com as organizações públicas, uso intensivo da tecnologia da informação e comunicação, e crescente utilização e importância da Internet viabilizaram o surgimento de uma plataforma denominada de governo aberto.

description: From 1992 to 2005, six factors
contributed to the U.S. housing boom:
mortgage rates decreased to generational
lows; financing innovations lowered
homeownership costs; home listings were
centralized on the Internet (to minimize
transaction costs); lenders gave priority to
minority homeownership; demographic
influences strengthened housing demand;
and real estate was perceived as a safe
haven for household wealth compared to
the stock market, which offered poor
investment returns.
These factors, combined with record volume
home sales, increased home appreciation,
record homeownership rates, and
sizable increases in mortgage originations, have lead many economists to the conclusion
that there is a national housing boom.
Industry economists recognize that price
gains have been unusually strong in recent
years because of robust housing demand
and increasingly stringent supply constraints
in some areas, which have boosted
price appreciation above the rate of
income growth. A stable relationship
between income and house prices over
time suggests the absence of a nationwide
housing bubble, especially when placed in
the context of a national unemployment
rate below 6 percent, extremely low mortgage
rates, and the acceleration of a broader
economy.
