Cross-Border Connectivity Begins with Regulatory Alignment Between Brazil and the U.S
Creators: name: frangieh, joseph

description: Much of what governs Brazilian society has its roots in American society, and it's no coincidence that Brazil was officially named the "United States of Brazil" from 1889 to 1968. This influence can be seen in Brazil’s economic system, legal and constitutional frameworks, technological advances, the pharmaceutical industry, healthcare, education, and even in tourism—where the United States is not only a top destination for Brazilians but often a dream for migration.

Aviation is no exception, for two main reasons: one is cultural, and the other is the pioneering role the United States has played in aviation and aerospace technology.

In recent years, commercial aviation has experienced significant growth in the relationship between Brazil and the U.S., driven by an increase in trade, cultural exchange, and tourism. Air connectivity between the two countries has become a key factor in strengthening these ties, and in this context, airline pilots play a crucial role—not only as aircraft operators but also as enablers of a continually expanding market.

This article explores some of the operational, regulatory, and cultural differences between commercial aviation in Brazil and in the U.S., highlighting how these aspects impact a pilot’s work and underscore their importance in an increasingly interconnected environment.

One of the most significant differences lies in Licensing and Certification. In Brazil, ANAC (Agência Nacional de Aviação Civil) is the authority responsible for regulating and certifying pilots and aircraft. In the U.S., this role is performed by the FAA (Federal Aviation Administration). While both agencies adhere to international standards set by ICAO (International Civil Aviation Organization), there are differences in flight hour requirements, medical examinations, and pilot training.

Although an FAA license can be validated for ANAC certification, the FAA does not validate licenses issued by ANAC or any other foreign authority. A pilot certified in both countries must understand and adapt to the differences between these systems. For a pilot with only ANAC certification to fly in the U.S., the flight must take place in a Brazilian-registered aircraft.

Another area of divergence is in Flight Rules and Operational Procedures. In the U.S., operations are governed by the FAR (Federal Aviation Regulations), while in Brazil, the governing rules are the RBAC (Regulamento Brasileiro da Aviação Civil). The differences can be subtle but significant—especially in terms of flight limits, approach procedures, and airspace regulations. Pilots who operate under both jurisdictions must be aware of these variations, especially on international routes.

Therefore, understanding regulatory norms is essential as an introduction to the world of connectivity between Brazil and the U.S.—and, gradually, to Europe, the Middle East, and Asia as well.

description: Exchange of antimicrobial resistance genes via mobile genetic elements occur in the gut which can be transferred from mother to neonate during birth. This study is the first to analyse transmissible colistin resistance gene, mcr, in pregnant mothers and neonates. Samples were collected from pregnant mothers (rectal) and septicaemic neonates (rectal and blood) and analysed for the presence of mcr, its transmissibility, genome diversity, and exchange of mcr between isolates within an individual and across different individuals (not necessarily mother–baby pairs). mcr-1.1 was detected in rectal samples of pregnant mothers (n = 10, 0.9%), but not in neonates. All mcr-positive mothers gave birth to healthy neonates from whom rectal specimen were not collected. Hence, the transmission of mcr between these mother-neonate pairs could not be studied. mcr-1.1 was noted only in Escherichia coli (phylogroup A & B1), and carried few resistance and virulence genes. Isolates belonged to diverse sequence types (n = 11) with two novel STs (ST12452, ST12455). mcr-1.1 was borne on conjugative IncHI2 bracketed between ISApl1 on Tn6630, and the plasmids exhibited similarities in sequences across the study isolates. Phylogenetic comparison showed that study isolates were related to mcr-positive isolates of animal origin from Southeast Asian countries. Spread of mcr-1.1 within this study occurred either via similar mcr-positive clones or similar mcr-bearing plasmids in mothers. Though this study could not build evidence for mother–baby transmission but the presence of such genes in the maternal specimen may enhance the chances of transmission to neonates.

description: Staphylococcus aureus is the most important pathogen of Sea foods. food poisoning happens in human due to consuming aqua products contamination  with this bacteria and its enterotoxin. The procedure for maintenance and preserve the quality of these products are important for the production and growth of pathogenic bacteria and toxin production from fishing time and transporting them to stores until they are consumed.

A total of 600 samples, containing 300 shrimps and 300 fishes( fresh and frozen ,farm and marine ) were studied, in order to detection of Staphylococcusaureus according to Iran National Standard From September 2013 to September 2014. Baird Parker agar containing egg-yolk and tellurite emulsion were used for isolation. Isolates were identified using the following criteria: production of coagulase, DNase, catalase, mannitol fermentation , hemolytic zone on 5% sheep blood agar, VP test and Gram staining.

 In total 206(34.3%) sample inclusive 84 shrimps (28%)and 122 fishes (40.7%) were contaminated with Staphylococcus aureus. Due to the presence of Staphylococcus aureus in fishes and shrimps, enforcement of quality control standards by the fisheries and careful monitoring of fishing and farming and preparation, freezing and transporting of marine products as well as health of workers are essential.

description: Multinationals increasingly require a cadre of skilled managers to effectively run their global operations. This exploratory study examines the relationship between emotional intelligence (EI) and managerial effectiveness among three cultures. EI is conceptualized and measured as self-other agreement concerning the use of managerial skills using data gathered under a 360-degree feedback process. Three hypotheses relating to managerial self-awareness of both interactive and controlling skills are examined using data from 3,785 managers of a multinational firm located in the United States (US), United Kingdom (UK), and Malaysia. The two sets of managerial skills examined were found to be stable across the three national samples. The hypotheses were tested using polynomial regressions, and contour plots were developed to aid interpretation. Support was found for positive relationships between effectiveness and EI (self-awareness). This relationship was supported for interactive skills in the US and UK samples and for controlling skills in the Malaysian and UK samples. Self-awareness of different managerial skills varied by culture. It appears that in low power distance (PD) cultures such as the United States and United Kingdom, self-awareness of interactive skills may be crucial relative to effectiveness whereas in high PD cultures, such as Malaysia self-awareness of controlling skills may be crucial relative to effectiveness. These findings are discussed along with the implications for future research.

description: We present a theory of spinor superfluidity in a two-species heteronuclear ultracold fermionic atomic gas consisting of arbitrary half-integer spin and one-half spin atoms. In particular, we focus on the magnetism of the superfluid phase and determine the possible phases in the absence of a magnetic field. Our work demonstrates similarities between heteronuclear fermionic superfluids and spinor Bose-Einstein condensates at the mean-field level. Possible experimental situations are discussed.

description: Atom-dimer exchange and dissociation reaction rates are predicted for different combinations of two $^4$He atoms and one of the alkaline species among $^{6}$Li, $^{7}$Li and $^{23}$Na, by using three-body scattering formalism with short-range two-body interactions. Our study was concerned with low-energy reaction rates in which the $s-$, $p-$ and $d-$ wave contributions are the relevant ones. The $^4$He is chosen as one of the atoms in the binary mixture, in view of previous available investigations and laboratory accessibilities. Focusing on possible experimental cold-atom realizations with two-atomic mixtures, in which information on atom-dimer reaction rates can be extracted, we predict the occurrence of a dip in the elastic reaction rate for colliding energies smaller than 20 mK, when the dimer is the $^4$He$^{23}$Na molecule. We are also anticipating a zero in the elastic $p-$wave contribution for the $^4$He + $^4$He$^7$Li and $^4$He + $^4$He$^{23}$Na reaction processes. With weakly-bound molecules reacting with atoms at very low colliding energies, we interpret our results on the light of Efimov physics which supports model independence and robustness of our predictions. Specific sensitivities on the effective range were evidenced, highlighted by the particular inversion role of the $p-$ and $d-$waves in the atom exchange and dissociation processes.

The effective model is fitted to experimental data listed by the Particle Data Group. We predict numerous experimentally unknown decay widths and branching ratios. An overall agreement of theory (fit and predictions) with experimental data confirms the $\bar{q} q$ nature of the states and qualitatively validates the effective approach. Naturally, experimental clarification as well as advanced theoretical description is needed for trustworthy quantitative predictions, which is observed from some of the decay channels. Besides conventional spin-$3$ mesons, theoretical predictions for ratios of strong and radiative decays of a hypothetical glueball state $G_3 (4200)$ with $J^{PC} = 3^{--}$ are also presented.

description: We formulate a U(1) gauge theory of the Hubbard model in the slave-rotor representation. From this formalism it is argued that spin liquid phases may exist near the Mott transition in the Hubbard model on triangular and honeycomb lattices at half filling. The organic compound k-(BEDT-TTF)_2 Cu_2 (CN)_3 is a good candidate for the spin liquid state on a triangular lattice. We predict a highly unusual temperature dependence for the thermal conductivity of this material.

Publisher: name: European Journal of Social Impact and Circular Economy
Year: 2021

description: The research investigates the interplay of sustainable tourism, management, monitoring, destination life cycles and stakeholder involvement in Sardinia destinations. Management techniques are considered critical to the sustainable stewardship and competitiveness of tourism destinations, especially in an island context where tourism is business all year round and all seasons. The importance of tourism management and monitoring in destinations and organizations is particularly highlighted through an explanation of sustainable tourism indicator systems such as that created by the European Commission. Systems such as this will help position Europe as the leading sustainable tourism destination in the world both now and in the future. The research followed an inductive approach. According to the general principles of the inductive methodology, knowledge is gathered from detailed observation of facts. This study permits to adopt of multiple research methods, both qualitative and quantitative. The analysis is grounded in documents, direct observations and questionnaires. In the first phase, only qualitative methods were utilized. This classification is supported by the assessor answers: moderate to the low development of tourism; partial participation of the local community with some facilities provided to visitors; a clear tourism season and emerging tourism markets; high to moderate tourism impacts respectively on destination A (North Sardinia) and B (South Sardinia); and a level of contact between tourists and the local population that can be classified as low in the Destination A and between low and moderate in Destination B. The effects of public policies and tourism development cannot be measured only in economic terms, such as return on investments, tourist expenditures, jobs and the like, but in terms of the well-being of residents in the area and consequently, the happiness of tourists and other visitors.

description: We introduce a new family of coherent states for loop quantum gravity, inspired by the twisted geometry parametrization. We compute their peakedness properties and compare them with the heat-kernel coherent states. They show similar features for the area and the holonomy operators, but improved peakedness in the direction of the flux. At the gauge-invariant level, the new family is built from tensor products of coherent intertwiners. To study the peakedness of the holonomy operator, we introduce a new shift operator based on the harmonic oscillator representation associated with the twisted geometry parametrization. The new shift operator captures the components of the holonomy relevant to disentangle its action into a simple positive shift of the spins.

description: A highly conductive metallic gas that is quantum mechanically confined at a solid-state interface is an ideal platform to explore nontrivial electronic states that are otherwise inaccessible in bulk materials. Although two-dimensional electron gas (2DEG) has been realized in conventional semiconductor interfaces, examples of two-dimensional hole gas (2DHG), which is the counter analogue of 2DEG, are still limited. Here, we report the observation of a 2DHG in solution-processed organic semiconductors in conjunction with an electric double-layer using ionic liquids. A molecularly flat single crystal of high mobility organic semiconductors serves as a defect-free interface that facilitates two-dimensional confinement of high-density holes. Remarkably low sheet resistance of 6 k$Ω$ and high hole gas density of 10$^{14}$ cm$^{-2}$ result in a metal-insulator transition at ambient pressure. The measured degenerated holes in the organic semiconductors provide a broad opportunity to tailor low-dimensional electronic states using molecularly engineered heterointerfaces.
Social indicators for businesses’ circular economy: multi-faceted analysis of employment as an indicator for sustainability reporting
Creators: name: Scarpellini, Sabina
Publisher: name: European Journal of Social Impact and Circular Economy
Year: 2021

description: In recent years, the introduction of the circular economy’s principles at the micro level is receiving attention in different domains of business literature. Although several studies have focused on the environmental or economic impacts of the adoption of the circular economy at a micro level, detailed analysis of the social aspects of the circular economy in businesses is necessary. From a triple bottom line perspective, social dimensions of the circular economy are one of the three pillars for sustainability accounting and reporting and must be considered in the relationship between firms and their stakeholders. Thus, the main objective of this study is to reflect on the social impact of the business circular economy at the micro level by analysing job generation. As one of this study’s contributions to the literature, it approaches the definition of different indicators inherent to different aspects of the employment in a circular economy framework. To reflect on the social metrics related to employment in circular businesses, this article summarises the results of semi-structured interviews collected in a regional case study in Spain and offers a schematic view of the multi-faceted analysis conducted.

Observations of changes of the characteristics of the oscillations (frequency, amplitude and polarization) in course of time, together with the theoretical analysis of the fitted model, would enable us to localize the stressed zone on the boundary of the plate and estimate the risk of a powerful earthquake at the zone.

Declines occurred in Haiti, Jamaica, Trinidad and Tobago, Argentina, Ecuador, Paraguay, and Uruguay. Among commodities, production increases occurred for wheat, corn, sugar, coffee, soybeans, sorghum, dry beans, pork and milk. Rice and banana output declined while cotton production changed little. The average person in Latin America probably had less food available from domestic production in 1971 than in 1970. U.S. agricultural exports to the Western Hemisphere increased 9 percent, reaching $1.3 billion. U.S. agricultural imports from the Hemisphere declined slightly. The Hemisphere's prospects for 1972 include more sugar but less corn output, and a continued low level of beef exports.

description: Purpose of this research is to investigate the impact of agile project management methodology on project success, as well as the role organizational support as moderator between agile project management methodology and project success. The data for this study has been collected from Telecommunication Services Provider Industry of Pakistan. Total sample size of 197 professionals was recorded. A questionnaire was distributed among the participants via hard copy and internet survey websites. Using collected data, we tested the effect of agile project management methodology on project success and further examined the moderating effect of organizational support between agile project management methodology and project success. The examination included Pearson’s correlation coefficient as well as regression using IBM SPSS Statistics Version 20. Results indicated that project management methodology has a strong correlation with project success and this correlation is not moderated by organizational support. The research findings have practical implications both in organization and project manager’s perspectives. Our research was limited to specific geographic area due to time and cost constraints. Future researchers may opt to conduct the study in other geographic areas of Pakistan and different industry including additional and different moderating variables.

description: Structural phase transitions between semiconductors and topological insulators have rich applications in nanoelectronics but are rarely found in two-dimensional (2D) materials. In this work, by combining ab initio computations and evolutionary structure search, we investigate two stable 2D forms of gold(I) telluride (Au$_{2}$Te) with square symmetry, noted as s(I)- and s(II)-Au$_{2}$Te. s(II)-Au$_{2}$Te is the global minimum structure and is a room-temperature topological insulator. s(I)-Au$_{2}$Te is a direct-gap semiconductor with high carrier mobilities and unusual in-plane negative Poisson's ratio. Both s(I) and s(II) phases have ultra-low Young's modulus, implying high flexibility. By applying a small tensile strain, s(II)-Au$_{2}$Te can be transformed into s(I)-Au$_{2}$Te. Hence, a structural phase transition from a room-temperature topological insulator to an auxetic semiconductor is found in the 2D forms of Au$_{2}$Te, which enables potential applications in phase-change electronic devices. Moreover, we elucidate the mechanism of the phase transition with the help of phonon spectra and group theory analysis.
Merger-Induced Starbursts

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Extragalactic starbursts induced by gravitational interactions can now be studied from z = ~0 to ~2. The evidence that mergers of gas-rich galaxies tend to trigger galaxy-wide starbursts is strong, both statistically and in individual cases of major disk-disk mergers. Star formation rates appear enhanced by factors of a few to ~10^3 above normal. Detailed studies of nearby mergers and ULIRGs suggest that the main trigger for starbursts is the rapidly mounting pressure of the ISM in extended shock regions, rather than high- velocity, ~50 - 100 km/s cloud-cloud collisions. Numerical simulations demonstrate that in colliding galaxies the star formation rate depends not only on the gas density, but crucially also on energy dissipation in shocks. An often overlooked characteristic of merger-induced starbursts is that the spatial distribution of the enhanced star formation extends over large scales (~10 - 20 kpc). Thus, although most such starbursts do peak near the galactic centers, young stellar populations pervade merger remnants and explain why (1) age gradients in descendent galaxies are mild and (2) resultant cluster systems are far-flung. This review presents an overview of interesting phenomena observed in galaxy-wide starbursts and emphasizes that such events continue to accompany the birth of elliptical galaxies to the present epoch.

Barangay Governance in Northeast of Catanduanes, Philippines: Basis for Catanduanes State University Panganiban Campus Extension Program
Creators: name: Floranza, Jaymund Marino

description: Governance is an act or a process of governing with power and performing the duties and functions within one's jurisdiction. Barangay governance gives an important role in setting direction to the people in the barangay level. It is an empowerment of the local government units in the country where this present study is interested. This quantitative-qualitative research study intended to look into the Barangay Governance Capabilities among Barangay Captains in Northeast of Catanduanes, Philippines as basis for Catanduanes State University Panganiban Campus Extension Program. The data gathered through the questionnaire and interview guide concluded that the Respondent-Barangay Officials in Northeast of Catanduanes are in the Middle Age, Male, College Level in Educational Attainment, Barangay Council Members and a neophyte in barangay governance having served for three years and below as barangay officials. The indicators of governance revealed that Barangay Captains are more equipped with Barangay Fiscal Administration than in Legislative and Judicial functions. The unstructured interview about the problems regarding the governance capabilities of barangay captains reveals the incompetence of the Barangay Captains, the non-cooperation of the residents or the constituents themselves, and the non-cooperative Barangay Kagawad that genuinely affects the capability of the Barangay Captain. Given the situation, the study recommends that barangay officials, particularly the barangay captains, are enjoined to attend the Barangay Governance Capability training seminar.

description: Failure and fault slip in crystalline rocks is associated with dilation. When pore fluids are present and drainage is insufficient, dilation leads to pore pressure drops, which in turn lead to strengthening of the material. We conducted laboratory rock fracture experiments with direct in-situ fluid pressure measurements which demonstrate that dynamic rupture propagation and fault slip can be stabilised (i.e., become quasi-static) by such a dilatancy strengthening effect. We also observe that, for the same effective pressures but lower pore fluid pressures, the stabilisation process may be arrested when the pore fluid pressure approaches zero and vaporises, resulting in dynamic shear failure. In case of a stable rupture, we witness continued prolonged slip after the main failure event that is the result of pore pressure recharge of the fault zone. All our observations are quantitatively explained by a spring-slider model combining slip-weakening behaviour, slip-induced dilation, and pore fluid diffusion. Using our data in an inverse problem, we estimate the key parameters controlling rupture stabilisation, fault dilation rate and fault zone storage. These estimates are used to make predictions for the pore pressure drop associated with faulting, and where in the crust we may expect dilatancy stabilisation or vaporisation during earthquakes. For intact rock and well consolidated faults, we expect strong dilatancy strengthening between 4 and 6 km depth regardless of ambient pore pressure, and at greater depths when the ambient pore pressure approaches lithostatic pressure. In the uppermost part of the crust ($<4$ km), we predict vaporisation of pore fluids that limits dilatancy strengthening. The depth estimates where dilatant stabilisation is most likely coincide with geothermal energy reservoirs in crystalline rock and in regions where slow slip events are observed.

Analytical Results for the Statistical Distribution Related to Memoryless Deterministic Tourist Walk: Dimensionality Effect and Mean Field Models

description: Consider a medium characterized by N points whose coordinates are randomly generated by a uniform distribution along the edges of a unitary d-dimensional hypercube. A walker leaves from each point of this disordered medium and moves according to the deterministic rule to go to the nearest point which has not been visited in the preceding μsteps (deterministic tourist walk). Each trajectory generated by this dynamics has an initial non-periodic part of t steps (transient) and a final periodic part of p steps (attractor). The neighborhood rank probabilities are parameterized by the normalized incomplete beta function I_d = I_{1/4}[1/2,(d+1)/2]. The joint distribution S_{μ,d}^{(N)}(t,p) is relevant, and the marginal distributions previously studied are particular cases. We show that, for the memory-less deterministic tourist walk in the euclidean space, this distribution is: S_{1,d}^{(\infty)}(t,p) = [Γ(1+I_d^{-1}) (t+I_d^{-1})/Γ(t+p+I_d^{-1})] δ_{p,2}, where t=0,1,2,...,\infty, Γ(z) is the gamma function and δ_{i,j} is the Kronecker's delta. The mean field models are random link model, which corresponds to d \to \infty, and random map model which, even for μ= 0, presents non-trivial cycle distribution [S_{0,rm}^{(N)}(p) \propto p^{-1}]: S_{0,rm}^{(N)}(t,p) = Γ(N)/\{Γ[N+1-(t+p)]N^{t+p}\}. The fundamental quantities are the number of explored points n_e=t+p and I_d. Although the obtained distributions are simple, they do not follow straightforwardly and they have been validated by numerical experiments.

Multiplicity Difference between Heavy and Light Quark Jets Revisited

description: The perturbative QCD approach to multiparticle production predicts a characteristic suppression of particle multiplicity in a heavy quark jet as compared to a light quark jet. In the Modified Leading Logarithmic Approximation (MLLA) the multiplicity difference δ_{Q\ell} between heavy and light quark jets is derived in terms of a few other experimentally measured quantities. The earlier prediction for b-quarks needs revision in the light of new experimental results and the improvement in the understanding of the experimental data. We now find δ_{b\ell}=4.4\pm0.4. The updated MLLA results on δ_{b\ell} and δ_{c\ell} are compared with the present data from e^+e^- annihilation. Their expected energy independence is confirmed within the energy range between 29 and 200 GeV; the absolute values are now in better agreement with experiment than in the previous analysis, and the remaining difference can be attributed largely to next-to-MLLA contributions, an important subset of which are identified and evaluated.

description: Structure in the di-$J/ψ$ mass spectrum observed by the LHCb experiment around 6.9 and 7.2 GeV is interpreted in terms of $J^{PC}=0^{++}$ and $2^{++}$ resonances between a $cc$ diquark and a $\bar c \bar c$ antidiquark, using a recently confirmed string-junction picture to calculate tetraquark masses. The main peak around 6.9 GeV is likely dominated by the $0^{++}(2S)$ state, a radial excitation of the $cc$-$\bar c \bar c$ tetraquark, which we predict at $6.871\pm 0.025$ GeV. The dip around 6.75 GeV is ascribed to the opening of the \Swave\ di-$χ_{c0}$ channel, while the dip around 7.2 GeV could be correlated with the opening of the di-$η_c(2S)$ or $Ξ_{cc} \bar Ξ_{cc}$ channel. The low-mass part of the di-$J/ψ$ structure appears to require a broad resonance consistent with a predicted $2^{++}(1S)$ state with invariant mass around $M_{\rm inv} = 6400$ MeV. Implications for $bb \bar b \bar b$ tetraquarks are discussed.

description: We consider the unbinding of a directed polymer in a random media from a wall in $d=1+1$ dimensions and a simple one-dimensional model for DNA unzipping. Using the replica trick we show that the restricted partition functions of these problems are {\em identical} up to an overall normalization factor. Our finding gives an example of a generalization of the stochastic matrix form decomposition to disordered systems; a method which effectively allows to reduce dimensionality of the problem. The equivalence between the two problems, for example, allows us to derive the probability distribution for finding the directed polymer a distance $z$ from the wall. We discuss implications of these results for the related Kardar-Parisi-Zhang equation and the asymmetric exclusion process.

Erasing a majority-logic bit

description: We study finite-time bit erasure in the context of majority-logic decoding. In particular, we calculate the minimum amount of work needed to erase a majority-logic bit when one has full control over the system dynamics. Although a single unit bit is easier to erase in the slow-driving limit, the majority-logic bit outperforms the single unit bit in the fast-erasure limit. Our results also suggest optimal design principles for majority-logic bits under limited control.
A preferential attachment model with Poisson growth for scale-free networks

description: We propose a scale-free network model with a tunable power-law exponent. The Poisson growth model, as we call it, is an offshoot of the celebrated model of Barabási and Albert where a network is generated iteratively from a small seed network; at each step a node is added together with a number of incident edges preferentially attached to nodes already in the network. A key feature of our model is that the number of edges added at each step is a random variable with Poisson distribution, and, unlike the Barabási-Albert model where this quantity is fixed, it can generate any network. Our model is motivated by an application in Bayesian inference implemented as Markov chain Monte Carlo to estimate a network; for this purpose, we also give a formula for the probability of a network under our model.

A study on the seismic behaviour of 52-storey steel frame building
Creators: name: Ding, Yuming
Publisher: name: University of British Columbia

description: Comparison of recorded structural earthquake response and theoretical dynamic analysis is vital to the study of earthquake engineering nowadays. This comparison could be either in the frequency domain by utilizing system identification algorithms or in the time domain by comparing response time histories. Not only had seldom previous studies done this comparison, but also less attention was paid to the three-dimensional nonlinear dynamic behaviour despite the fact that it has been generally admitted that three-dimensional response is important in inelastic behavior of buildings. The purpose of this research is to study the seismic behaviour of a well-instrumented 52-storey steel frame building in Los Angeles, California. This building has been subjected to ground motions from several earthquakes among which the 1991 Sierra Madre earthquake and the 1994 Northridge earthquake were selected in this study. During both earthquakes the building responses appeared to remain in the linear range. Detailed frequency domain analyses of the recorded motions from these two earthquakes were conducted to determine the dynamic characteristics of the structure. Three-dimensional nonlinear dynamic computer analyses were then employed to evaluate the response of the structure induced by other earthquake excitations. Dynamic characteristics and seismic responses from the above two approaches hence could be compared to yield valuable information. The results of this study showed that by performing a linear three-dimensional analysis, the actual response of a building during past earthquakes could be reproduced with confidence. By further performing a nonlinear three-dimensional analysis, the state and sequence of damage could also be predicted. Traditional Nonlinear Static Procedure (NSP, pushover analysis) has the deficiency of excluding the higher mode participation which becomes obvious for highrise buildings. Improvements to the NSP were explored. Because of the torsional response for highrise buildings, two-dimensional analysis is not feasible to reliably predict their nonlinear response during earthquakes.
