Ridesharing and Digital Resilience for Urban Anomalies: Evidence from NYC Taxi Market

Urban anomalies bring uncertainties to society, urban transportation systems, and businesses. Some urban anomalies, such as no-notice and/or unpredictable terrorist attacks or other urban strikes, if not handled in timely ways, may result in loss of life or property and pose tremendous risks to public safety overall. Previous studies have focused on developing emergency-management technology but without in-depth analysis exploring how technology-mediated digital systems perform in reality. Besides, the recent literature has demonstrated significant interest in analyzing and comparing the traditional on-demand service (i.e., taxies) and ridesharing platforms (e.g., Uber). A majority of prior studies have focused on their complementary roles in determining environmental conditions. Little is known, however, regarding how and why the two types of platforms perform in contexts of uncertainty (e.g., under emergency situations). This paper aims to bridge this literature gap. Specifically, we consider different types of unexpected urban anomalies (including terrorist attacks, car crashes, and subway shutdowns) and collect large-scale trip data on taxi and ridesharing services. Empirically, we employ a difference-in-differences (DiD) econometric model to compare the platform-level performances (measured by the number of fulfilled trips) of a traditional taxi system and a ridesharing platform after urban anomaly shocks. We observe that the ridesharing platform significantly outperforms the traditional taxi platform in coping with the uncertainties brought about by unexpected anomalies. We conduct a set of robustness checks to verify our findings and propose multiple possibilities to explain them. We conclude, conservatively, that the technological effect, as well as the technology-enabled supply elasticity of the digital platforms, are the main factors determining the differences between the platforms during an urban anomaly. This work offers important insights into the design of platform strategies, especially for the stimulation of the labor supply and incentivization of the adoption and use of technology in urban transportation systems in response to anomalous urban upheavals.
Experimental deformation of synthetic wet jadeite aggregates

[1] Predictions on interplate coupling and shear heating in the deeper levels of subduction zones require an understanding of the rheology of eclogite. The strength of eclogite is probably limited by the flow strength of its major constituent omphacite, representing a solid solution between the clinopyroxene end-members diopside and jadeite. Here we report the results of deformation experiments on the end-member jadeite (NaAlSi2O6), carried out on fine-grained synthetic aggregates crystallized in the stability field of jadeite from a synthetic glass precursor. A standard procedure was established to yield samples with a uniform microstructure and an average grain size of approximately 10 μm. The presence of micropores and the detection of small amounts of freezable water by Fourier transform infrared spectroscopy (FTIR) in both undeformed and deformed samples indicates the presence of a free aqueous fluid, hence wet conditions. Deformation experiments were carried out in a modified Griggs-type apparatus at a confining pressure of 2.5 GPa, temperatures between 800°C and 1100°C and at strain rates of 4 × 10−4 s−1 to 2 × 10−6 s−1. A molten eutectic CsCl/NaCl mixture was used as pressure medium. The microfabrics of the deformed samples and the mechanical data indicate deformation in the dislocation creep regime. The mechanical data are fit by a power law using a global inversion method, yielding an activation energy of Q = 326 ± 27 kJ mol−1, a stress exponent n = 3.7 ± 0.4, and a preexponential factor of ln A = −3.3 ± 2.0. Extrapolation of this flow law for synthetic jadeitite to low geological strain rates, and comparison with available flow laws for diopside, indicates jadeite to be significantly weaker than diopside in the dislocation creep regime.
Neuropsychological approach of the processes of orientation of the visuospatial attention and concentration maintenance on under-13 athletes of field soccer

The visual attention and concentration are psychological valences that can be related to different neural ways and different cognitive processes. With this work, we intend to bring, in the light of Sports Sciences, the contribution of a single physical training session and a single mental training session for the improvement of visual attention and concentration. The results for the physical training session showed significant differences on concentration assessment, but no significant difference for bottom-up processes of visuospatial attention. However the results for the mental training session showed significant differences on both situations. © Cien. Cogn. 2010; Vol. 15 (2): 142-154.
miR-483-3p promotes IL-33 production from broblast-like synoviocytes by regulating ERK signaling in rheumatoid arthritis

Our previous identi�ed miR-483-3p to be highly expressed in synoviocytes from patients with rheumatoid arthritis (RA); however, its effects on in�ammation of RA broblast-like synoviocytes (FLSs) have remained unclear. The expression of miR-483-3p and cytokines in RA FLSs was detected using quantitative real-time polymerase chain reaction. Enzyme-linked immunosorbent was conducted to determine interleukin (IL)-33 production from RA FLSs. Western blotting was employed to quantify the levels of p-ERK and total ERK. Overexpressed miR-483-3p signi�cantly increased the mRNA and protein expression of IL-33, but not of IL-27 or IL-34, in RA FLSs, whereas miR-483-3p suppression showed the opposite effects. Furthermore, miR-483-3p upregulation activated the ERK signaling pathway. The ERK signaling inhibitor PD98059 partly reversed the elevation of IL-33 levels mediated by miR-483-3p overexpression. Our results reveal that miR-483-3p promotes IL-33 expression by regulating the ERK signaling pathway in RA FLSs. Thus, miR-483-3p may be a potential effective target for RA treatment.
Fungal Systematics and Evolution

: This article re-evaluates the taxonomy of Hyphoderma macaronesicum based on various strategies, including the cohesion species recognition method through haplotype networks, multilocus genetic analyses using the genealogical concordance phylogenetic concept, as well as species tree reconstruction. The following loci were examined: the internal transcribed spacers of nuclear ribosomal DNA (ITS nrDNA), the intergenic spacers of nuclear ribosomal DNA (IGS nrDNA), two fragments of the protein-coding RNA polymerase II subunit 2 ( RPB 2), and two fragments of the translation elongation factor 1-α ( EF1-α ). Our results indicate that the name H. macaronesicum includes at least two separate species, one of which is newly described as Hyphoderma paramacaronesicum . The two species are readily distinguished based on the various loci analysed, namely ITS, IGS, RPB 2 and EF1-α.
PARALLELIZATION OF ULTRASOUND SIMULATIONS USING 2D DECOMPOSITION

This thesis is a part of the k-Wave project, which is a toolbox for the simulation and reconstruction of acoustic wave felds and one of its main contributions is the planning of focused ultrasound surgeries (HIFU). One simulation can take tens of hours and about 60% of the simulation time is taken by the calculation of the 3D Fast Fourier transforms. Up until now the 3D FFT has been calculated purely by the FFTW library and its 1D decomposition, whose major limitation is the maximum number of employable cores. Therefore we introduce a new approach, called the 2D hybrid decomposition of the 3D FFT (HybridFFT), where we combine both MPI processes and OpenMP threads to reach as best performance as possible. On a low number of cores, on the order of a few hundreds, we are about as fast or slightly faster than FFTW and pure MPI 2D decomposition libraries (PFFT and P3DFFT). One of the best results was achieved on a 5123 FFT using 512 cores, where our hybrid version run 31ms, FFTW run 39ms and PFFT run 44ms. The most significant performance advantage should be seen when employing around 8–16 thousand cores, however we haven’t had an access to a machine with such resources. Almost a linear scalability has been proven for up to 2048 employed cores.

Strontium and neodymium isotopic compositions in sediments from Godavari, Krishna and Pennar rivers

We report here strontium (Sr) and neodymium (Nd) isotopic compositions in bed sediments from the Godavari, Krishna and Pennar rivers, draining into the Bay of Bengal. The isotopic compositions of these sediments range from 0.7190 to 0.7610 for 87 Sr/ 86 Sr and - 12.04 to -23.68 for e Nd . This wide range in Sr and Nd isotopes is derived from variable proportions of sediments from different rock types in their drainage basins. All the three rivers have their characteristic isotopic signatures. The results display highest 87 Sr/ 86 Sr (0.7610) and most negative e Nd values (-23.68) for the sediments of Pennar river. This is attributed to the chemical weathering of gneisses and granites in its drainage basin. The 87 Sr/ 86 Sr and e Nd values for the Godavari river sediments range from 0.7196 to 0.7210 and -15.31 to -18.22 respectively. 87 Sr/ 86 Sr and e Nd values in Krishna river sediments lie from 0.7217 to 0.7301 and -12.04 to -12.78 respectively. Our results show that the sedimentary load from the Godavari and Krishna rivers is primarily derived from the older rocks in their drainage basins. It is possible that the sediments transported through peninsular Indian rivers predominantly control Sr and Nd isotope sedimentary budget in the western Bay of Bengal.
Navigational Principles as Applied to Animals

A deeper understanding and love for the creatures with whom we share this planet must develop as we read the works of animal specialists. These great men and women will surely forgive a navigator who suggests alternative methods by which creatures may find their ways, methods which do not seem to conflict with the remarkable facts they have brought to light but which happen to conform to modern navigational principles.
Virtue Ethics and the Fundamental Attribution Error by

Ordinary moral thought often commits what social psychologists call ‘the fundamental attribution error’. This is the error of ignoring situational factors and overconfidently assuming that distinctive behaviour or patterns of behaviour are due to an agent’s distinctive character traits. In fact, there is no evidence that people have character traits (virtues, vices, etc.) in the relevant sense. Since attribution of character traits leads to much evil, we should try to educate ourselves and others to stop doing it.
Cold Outflow from the Faroe Bank Channel

Abstract The exchange of water between the Norwegian Sea and the North Atlantic around the Faroe Islands was investigated in 1987 and 1988 combining CTD data with shipborne Acoustic Doppler Current Profiler (ADCP)measurements. Tests were devised to assess the accuracy of the ADCP measurements and the results are described; it is found that estimating a reference velocity for geostrophic measurements is limited by the presence of tides of order 10 cm s−1. In the outflow of cold water from the Faroe Bank Channel, which reaches speeds of nearly 1 m s−1 the error is acceptably small but strong time dependent components are revealed. The discharge of cold water is traced 75 km beyond the sill of this channel and changes in potential temperature, salinity and potential vorticity on an isopycnal surface are attributed to intense mixing. An effective diffusivity near 100 cm2 s−1 is derived and K-H instability demonstrated as a plausible source of the turbulent energy. Six current meter moorings were deployed from.
The Pleistocene rivers of the English Channel region

The Pleistocene history of river systems that enter the English Channel from northern France and southern England is reviewed. During periods of low sea‐level (cold stages) these streams were tributaries of the Channel River. In southern England the largest, the River Solent, is an axial stream that has drained the Hampshire Basin from the Early Pleistocene or late Pliocene. Other streams of southern England may be of similar antiquity but their records are generally short and their sedimentary history have been destroyed, as in northern Brittany, by coastal erosion and valley deepening as a consequence of tectonic uplift. In northern France, the Seine and Somme rivers have very well developed terrace systems recording incision that began at around 1 Ma. The uplift rate, deduced from the study of these terrace systems, is of 55 to 60 m myr−1 since the end of the Early Pleistocene. Generally the facies and sedimentary structures indicate that the bulk of the deposits in these rivers accumulated in braided river environments under periglacial climates in all the area around the Channel. Evolution of the rivers reflects their responses to climatic change, local geological structure and long‐term tectonic activity. In this context the Middle Somme valley is characterised by a regular pattern in which incision occurs at the beginning of each glacial period within a general background of uplift. Nevertheless the response of the different rivers to climatic variations, uplift and sea‐level changes is complex and variable according to the different parts of the river courses.

Analog Modeling of Doubly Vergent Thrust Wedges

Two-dimensional scaled analog models of doubly vergent thrust systems produced a two-stage evolution for the development of asymmetric thrust wedges. Stage I was the rapid elevation of an axial zone bounded by a major retrovergent thrust system together with closely spaced, low-displacement provergent thrusts in its hanging wall. When a critical elevation of the axial zone was attained, Stage II deformation was characterized by the nucleation and propagation of high-displacement, provergent thrusts to form a critically tapered prowedge. The prowedge taper angle was typically 11–12, whereas the retrowedge maintained a steep surface taper of 38–42. During Stage II, the doubly vergent asymmetry increased. This was characterized by the formation of well-developed provergent thrust sheets and slower uplift of the retrowedge system. Overlapping prowedge thrusts showed synchronous displacements. Addition of synkinematic erosion and/or sedimentation produced dramatic changes to the doubly vergent wedges in the models. There were fewer prowedge thrusts, prolonged prowedge thrust activities, out-of-sequence thrusting, and reactivation of preexisting thrusts. Synkinematic growth strata recorded the progressive evolution of the wedge system and also the activities on individual thrusts. The final geometries of the analog models of doubly vergent thrust wedges closely replicated those of naturally occurring convergent and collisional orogens, such as the Pyrenees, the western Alps, and the Himalayas. The models provide important geometric and kinematic templates for understanding the development of orogenic thrust-and-fold belts. They emphasize the dynamic feedback between surface processes—synkinematic erosion and sedimentation—and thrust-belt evolution. Synchronous thrust activities, out-of-sequence thrusting, and interaction with erosion and sedimentation all need to be taken into account when one evaluates hydrocarbon generation, migration, and entrapment in thrust belts.
Communications of the Association for Information Systems Communications of the Association for Information Systems

: Research on digital nudging has become increasingly popular in the information systems (IS) community. In this paper, we overview the current progress of, critically reflect on, and discuss further research on digital nudging in IS. To do so, we reviewed the literature and interviewed Markus Weinmann from Rotterdam School of Management at Erasmus University, one of the first scholars who introduced digital nudging to the IS community, and Alexey Voinov, Director of the Centre on Persuasive Systems for Wise Adaptive Living at University of Technology Sydney. We uncovered a gap between what we know about what constitutes digital nudging and how we can actually put consequent requirements into practice. In this context, the original nudging concept bears inherent challenges about, for example, the focus on individuals’ welfare, which, thus, also apply to digital nudging. Moreover, we need to better understand how nudging in digital choice environments differs from that in the offline world. To further distinguish itself from other fields that already tested various nudges in many different domains, digital nudging research in IS may benefit from a design science perspective in order to go beyond testing effectiveness and provide specific design principles for the different types of digital nudges.
Development and preclinical evaluation of radioligands for the PET studies of cerebral adenosine A1 and A2A receptors

Vanwege het klinisch belang van adenosine A1 en A2A receptoren (A1Rs, A2ARs) is er een sterke behoefte aan het ontwikkelen van radioliganden met hoge affiniteit en subtype-selectiviteit ten einde de dichtheid van deze receptoren met PET in kaart te kunnen brengen. Het hoofddoel van dit proefschrift is de ontwikkeling van radioliganden met een hoge mate van selectiviteit, een affiniteit die hoog genoeg is om A2ARs te kunnen afbeelden maar niet zo hoog dat vaststelling van het aantal receptoren bemoeilijkt wordt. Er is gekeken naar goede farmacokinetische eigenschappen en een grotere signaal-ruisverhouding dan de bestaande radioliganden zoals [11C]SCH442416. Een retrosynthetische benadering werd toegepast voor de bereiding van niet-radioactieve fluoranaloga van SCH442416 en O-desmethyl preladenant. [18F]Fluoropropyl SCH442416 {[18F]FPSCH) en [11C]preladenant werden ontwikkeld als nieuwe liganden voor het afbeelden van A2ARs in de hersenen met behulp van PET. Liganden die met fluor-18 zijn gemerkt bieden logistieke voordelen boven 11C-radioliganden, en kunnen naar verafgelegen centra worden vervoerd die niet over een kostbaar on-site cyclotron beschikken. Bovengenoemde radioliganden konden worden gemaakt met hoge specifieke radioactiviteit en radiochemische zuiverheid. De verdeling van de radioliganden werd onderzocht met behulp van PET, ex vivo biodistributie en in vitro autoradiografie. De regionale verdeling van [18F]FPSCH en [11C]preladenant kwam overeen met de bekende verdeling van A2ARs in de hersenen van de rat, met de hoogste opname in het striatum. PET toonde aan dat [18F]FPSCH en [11C]preladenant een gunstige farmacokinetiek bezitten in de hersenen. De eigenschappen van beide tracers maken hen geschikt voor het afbeelden van A2A receptoren.
Linear AM decomposition for sinusoidal audio coding

We present a novel decomposition for sinusoidal audio coding using amplitude modulation of sinusoids via a linear combination of arbitrary basis vectors. The proposed method, which incorporates a perceptual distortion measure, is based on a relaxation of a non-linear least squares minimization. It offers benefits in the modeling of transients in audio signals. We compare the decomposition to constant-amplitude sinusoidal coding using rate-distortion curves and listening tests. Both indicate that, at the same bit-rate, perceptually significant improvements can be achieved using the proposed decomposition.
Degree project Tribonacci Cat Map A discrete chaotic mapping with Tribonacci matrix

Based on the generating matrix to the Tribonacci sequence, the Tribonacci cat map is a discrete chaotic dynamical system, similar to Arnold’s discrete cat map, but on three dimensional space. In this thesis, this new mapping is introduced and the properties of its matrix are presented. The main results of the investigation prove how the size of the domain of the map affects its period and explore the orbit lengths of non-trivial points. Different upper bounds to the map are studied and proved, and a conjecture based on numerical calculations is proposed. The Tribonacci cat map is used for applications such as 3D image encryption and colour encryption. In the latter case, the results provided by the mapping are compared to those from a generalised form of the map.
Feature selection for hyperspectral data based on recursive support vector machines

In this article, a feature selection algorithm for hyperspectral data based on a recursive support vector machine (R‐SVM) is proposed. The new algorithm follows the scheme of a state‐of‐the‐art feature selection algorithm, SVM recursive feature elimination or SVM‐RFE, and uses a new ranking criterion derived from the R‐SVM. Multiple SVMs are used to address the multiclass problem. The algorithm is applied to Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) data to select the most informative bands and the resulting subsets of the bands are compared with SVM‐RFE using the accuracy of classification as the evaluation of the effectiveness of the feature selection. The experimental results for an agricultural case study indicate that the feature subset generated by the newly proposed algorithm is generally competitive with SVM‐RFE in terms of classification accuracy and is more robust in the presence of noise.
Bukti Korespondensi artikel Busy CEO and Financial Reporting Quality: Evidence from Indonesia Busy CEOs and financial reporting quality: evidence from Indonesia

Purpose –This study aims to examine the relationship between CEObusyness and financial reporting quality in a country which implements a two-tier board system. Design/methodology/approach – This study includes firms listed on the Indonesian Stock Exchange during the 2010–2018 period. This study employs an ordinary least squares regression, the propensity score matching procedure, and a Heckman two-stage regression in testing the hypothesis. Findings –This study finds that firmswith busy directors have a higher financial reporting quality, and these results are robust to a battery or sensitivity analysis. The additional analyses also find that a busy CEO is negatively associated with the firm’s financial reporting quality with decreasing income. Practical implications – This paper provides implications for policy-makers in the emerging market on devising policies on CEOs’ appointments, especiallywhen involvingmultiple directorships. Despite the general belief on the detrimental workload effects of busy directors, this study offers evidence supporting the opposite effect. Originality/value – As many previous studies focused on the effect of director busyness on firm’s performance, this study focusses on the effect of CEO busyness on financial reporting quality. To the best of our knowledge, this study is the first to investigate this issue in an emerging market.
Relationships among Mineralizable Soil Nitrogen, Soil Properties, and Climatic Indices

0 ) was estimated by curve fi tting using N mineralized from 2 to 24 wk, and Pool I, a labile mineralizable N pool, was determined as the N mineralized in the fi rst 2-wk period. Soil properties were relatively eff ective predictors of N 0 with soil organic N (SON) and sand explaining 40 and 34% of the variability, respectively. Particulate organic matter N (POM-N) and pH explained 18 and 25%, respectively, of the variability in Pool I. Simple climate normals were generally poor predictors of pool size except for potential evapotranspiration (PET), which predicted 24% of the variability in Pool I. Th e re_clim indices, normally applied to the activity of soil decomposers and applied here for the fi rst time to explain soil mineralizable N pool size variability, performed better than simple climate indices and explained up to 26% of the variation in N 0 . By including soil and climatic parameters in a multiple regression model, it was possible to explain about 63 and 40% of the variability in N 0 and Pool I, respectively, across a wide range of arable soils in Canada.
