A Novel Location Privacy Preservation Method for Moving Object

Location privacy has been a serious concern for mobile users who use location-based services to acquire geographical location. Spatial cloaking technique is a well-known privacy preserving method, which blurs an exact user location into a cloaked region to meet privacy requirements. In this paper, we propose a new semantic privacy preservation method rely on the well-established k-anonymity and l-diversity privacy metrics for semantic cloaking. We also define a representative cloaking region which helps in communication cost reduction caused by user movement. Experimental implementation and analysis exhibit that our proposed method renders good performance in efficiency and scalability. We also show that our proposed method outperforms the existing privacy preservation method by effectively enhance privacy against various adversaries.
A virtual tour of the Ibero-Armorican orocline

Dynamic content features, such as animations, videos or 3D representations are useful tools to explain dynamic geological processes. Modern technologies permit development of animations that are more illustrative and instructive than the classic static figures traditionally used in scientific papers. In addition, the use of supplemental files in traditional journals, and especially within new electronic journals, permit inclusion of interactive content as an analogue to the dynamic nature of geological processes. We present a collection of dynamic animations based on previous data. These animations are used to deliver ideas about the kinematic and mechanical development of the Ibero-Armorican orocline and to illustrate the complex evolution and timing of orocline formation, its tectonic setting on a regional and global-scale, and its implications for the modification of the lithosphere during orogeny.

IPO certification : The role of grading and transparent books

India has the unique distinction of grading its IPOs and demonstrating the IPO bookbuilding process to investors. In the context of this backdrop we investigate the certification role of these mechanisms in bookbuilt IPOs in India. We find that contrary to the expectations, grading does not affect the underpricing of IPOs. We also find that though grading was introduced to help retail investors, it is instead being used by informed institutional investors to make their investment decisions in Indian IPOs. However, the benefits of grading do pass on to the retail investors, albeit indirectly. We show that the transparency of the IPO bookbuilding process offers a much stronger certification signal to retail investors as compared to that of IPO grading. Known certification mechanisms such as the reputation of the sponsor or VC affiliation are of limited importance in the Indian IPO market.
Culture-Tetradecanoylphorbol-13-acetate in Mouse Epidermal Cell O Phosphorylation by Calcium and 12-Induction of Common Patterns of Polypeptide Synthesis and Updated

Terminal differentiation can be induced in cultured basal cells by either increasing the Cai1* level in the medium from 0.05 to 1.4 mM or by exposure to the tumor promoter 12-O-terradecanoylphorbol-13-acetate (TPA). If ( 'a2* and TPA act by a common mechanism, then a common pattern of protein synthesis and/or phosphorylation would be expected. Computer-assisted analysis of radioactively labeled polypeptides sepa rated by two-dimensional-polyacrylamide gel electrophoresis was utilized to study protein synthesis and phosphorylation. Within l h of increasing the Ca2* level in the medium, the synthesis of 57 polypeptides was altered by 2-fold or more. Similarly, exposure to TPA for l h affected the synthesis of 106 polypeptides. Sixteen polypeptides were affected by both ( 'a:+ and TPA; the synthesis of nine was increased and seven was decreased, with changes in the same direction for both effectors. By 4 h, the synthesis of 32 polypeptides was similarly modulated by both Ca2* and TPA. Only one polypeptide which was increased at 1 h was still elevated at 4 h. These results suggest that a common dynamic program of protein synthesis, likely to be related to terminal keratinocyte differ entiation, is induced by both ( Â¡r * and TPA. Overall phosphorylation of epidermal proteins was increased after 30 min of TPA treatment, but was not increased by Ã‡a2*at this time. Keratin polypeptides were heavily phosphorylated in low Ca2* medium, but the level or pattern of phospho rylation of these proteins was not altered by either Ca2* or TPA. Although phosphorylation of a minor polypeptide (pi 5.ÃŒ/M, 45,000) was increased 2-3-fold by both Ã‡a2*and TPA, most of the specific protein phosphoryl ation changes induced in keratinocytes by Ca2* and TPA appear to be unique. Thus, if protein phosphorylation is an early signal for epidermal differentiation by each effector, only a single apparent common substrate is involved and multiple kinases are activated. Alternatively, substrate specificity of a single kinase may be differentially altered by each effector.
Inclusion of Ice Microphysics in the NCAR Community Atmospheric Model Version 3 (CAM3)

Abstract A prognostic equation for ice crystal number concentration together with an ice nucleation scheme are implemented in the National Center for Atmospheric Research (NCAR) Community Atmospheric Model version 3 (CAM3) with the aim of studying the indirect effect of aerosols on cold clouds. The effective radius of ice crystals, which is used in the radiation and gravitational settlement calculations, is now calculated from model-predicted mass and number of ice crystals rather than diagnosed as a function of temperature. A water vapor deposition scheme is added to replace the condensation and evaporation (C–E) in the standard CAM3 for ice clouds. The repartitioning of total water into liquid and ice in mixed-phase clouds as a function of temperature is removed, and ice supersaturation is allowed. The predicted ice water content in the modified CAM3 is in better agreement with the Aura Microwave Limb Sounder (MLS) data than that in the standard CAM3.

An IRT Scale Transformation Method for Parameters Calibrated From Multiple Samples of Subjects

A problem frequently confronted in IRT applications is that the item parameters calibrated using more than two independent samples of subjects must be expressed on the same scale. The existing methods were developed for a pairwise transformation, that is, from one scale to the other. The purpose of the present study is to introduce a common scale transformation method which can simultaneously find a vector of transformation functions for placing the parameter estimates from two or more item pools on a specified common scale. Two examples are presented to illustrate the usefulness of the method. Acknowledgment The author thanks Bradley Hanson, Tianyou Wang and Michael Kolen for their comments and suggestions in improving the manuscript. An IRT Scale Transformation Method For Parameters Calibrated From Multiple Samples of Subjects Because of the indeterminant nature of the latent variable IRT models, the parameter estimates obtained from different independent calibrations may not be on the same scale. A linear transformation can be performed to place them on an arbitrary scale while preserving the same item characteristic functions. The scale transformation procedure requires that at least some of the items be common to the different calibrations. A number o f procedures have been proposed for IRT scale transformation. Marco (1977) proposed using the mean and standard deviation of the 6-parameter estimates of the common items to determine the transformation function. Loyd and Hoover (1980) described a method which used the mean of the b-parameter estimates and mean o f the a-parameters estimates. Haebara (1980) and Stocking and Lord (1983) introduced loss-minimization methods for computing the transformation coefficients. These methods are based on minimizing a loss function that reflects the errors involved in the process of transforming the estimates of parameters in one metric to another. Baker and Al-Kami (1991) compared a loss-minimization method (Stocking & Lord, 1983) with a summary statistics based method (Loyd & Hoover, 1980). They found that the loss-minimization method was less sensitive to atypical combinations of underlying ability, item difficulty, and discrimination than are the methods based on summary statistics. IRT parameter scale transformation is a directional process, that is, from one scale to another scale. Baker and Al-Kami (1991) used the terms from and to to make the direction of transformation explicit. The existing methods are all for a pairwise transformation, that is, there is one from scale and one to scale. If there is a need to compare parameter estimates from more than two item pools, the current practice is to find the transformation functions in a number of independent pairwise processes. The purpose o f the present study is to introduce a common scale transformation method which can find a vector of transformation functions that place parameter estimates from two or more item pools on a common scale in one minimization process. Two examples are presented to illustrate the usefulness of the method.
Suction-Induced Hardening Effects on the Shear Modulus of Unsaturated Silt

AbstractThe small-strain shear modulus Gmax is a key material parameter in modeling the behavior of soils subjected to dynamic loading. Recent experimental results indicate that seasonal weather interaction with near-surface soils causes Gmax to change by up to an order of magnitude in some climates, with a hysteretic response upon drying and wetting. The increase in Gmax during drying and the stiffer response during subsequent wetting have been postulated to be due to plastic hardening during drying. To further understand this behavior, a series of isotropic compression tests were performed on compacted silt specimens at different values of matric suction to evaluate changes in the preconsolidation stress with suction. The Gmax values obtained previously on this silt matched well with a model using a hardening parameter independently derived from the isotropic compression tests, as well as the parameters of the soil water retention curve (SWRC). The model showed an increase in Gmax during drying from an .
Mindsets and Incidental Information 1 RUNNING HEAD: Mindsets and Incidental Information Mindsets and Pre-conscious Open-Mindedness to Incidental Information

Mindset theory (Gollwitzer, 1990) proposes that deliberative mindsets are marked by more openminded processing of information, whereas implemental mindsets are characterized by more closed-minded processing. Accordingly, deliberative and implemental mindsets should differ in selective processing of incidental information when performing a central task. In three experiments, participants in deliberative and implemental mindsets performed a computer task while randomly presented incidental, unavoidable words. A subsequent recognition memory test assessed selective processing of these incidental words. Results revealed that deliberative mindsets led to superior recognition memory, suggesting increased open-mindedness to processing incidental information. Implications for mindset and goal theories are discussed. Mindsets and Incidental Information 3 The cognitive processes that support and maintain goal pursuit have become a central issue among researchers studying motivation (Gollwitzer & Bargh, 1996; Kruglanski, Shah, Fishbach, Friedman, Chun, & Sleeth-Keppler, 2002; Oettingen & Gollwitzer, 2001; Sorrentino & Higgins, 1986). Mindset theory was one of the first theories to describe the complex interplay between cognitive and motivational processes, and continues to be one of the most prominent and influential frameworks (Gollwitzer, 1990). This theoretical model posits that there are multiple stages of goal pursuit, called action phases, which individuals must successfully navigate to attain a goal. In particular, the theory assumes that each phase is characterized by a distinct task that must be accomplished. The two most important of these tasks are choosing a goal and implementing a chosen goal. Whereas individuals must deliberate between the many wishes and desires they might have when choosing a goal, they must plan out when and how to act to implement a chosen goal. Central to the theory is the notion that actively choosing a goal and planning the implementation of a goal activates distinct mindsets, or cognitive procedures, that promote successful navigation through the respective action phases. The studies reported in this paper build upon and advance a body of research that has demonstrated the theoretical and empirical distinction between deliberative and implemental mindsets; that is, differences in information processing when one is engaged in choosing a goal as compared to implementing a
A Study of Development Scheme of Biosimulator

Intracellular molecular processes have been modeled and simulated on computational platforms [2, 3]. Already some attempts have been started for larger scale simulations such as human disease [5] and rice in silico models even at the level of the whole organism [1]. As for a computer program, the larger a target system becomes, the more a simulation program for the system becomes complicated. Therefore, a development scheme is required to obtain reliable large-scale biosimulation programs and should be investigated from engineering viewpoints. In this study, a development scheme of biosimulator based on assemblies of component models is proposed. Further, a eukaryotic cell cycle model [4] was programmed using MATLAB [6] and applied to Dictyostelium discoideum, and investigated.
A Study on Fault‐Type and Site‐Effect (VS30) Parameters in the Attenuation Relationships of Peak Ground Acceleration and Peak Ground Velocity in Ilan, Taiwan

The purpose of this study is to derive attenuation relationships of the peak ground acceleration (PGA) and peak ground velocity (PGV) in Ilan, Taiwan, including factors of fault type and site effect. A total of 2852 accelerograms recorded from 92 shallow earthquakes with Mw magnitude ranging from 4.0 to 7.7 are used to develop theregionalattenuationrelationships.Twomodelsareused:Model1usesrecordsfrom 65 strong-motion sites. The results will be especially useful for the Central Weather Bureau (CWB) early warning system to quickly assess and report the PGA and PGV maps for effective emergency-response operations. Model 2 uses records from the 46 strong-motion sites with available VS30 to incorporate a site-effect term, aiming to reduce the standard deviation of the predicted ground motion for engineering appli- cations. First, the results show that the fault-type amplification factor decreases faster with increasing magnitude for the strike-slip fault type than the reverse or normal fault types. In addition, from the intraevent residuals as function of distance of horizontal PGA for reverse earthquakes, we found clusters of higher PGAvalues at a distance of 110-130 km from events in southwestern areas. This was probably due to Moho re- flection along paths crossing the Central Mountain Range. Second, the PGVintraevent residual is more closely correlated with VS30 than that of the PGA because the latter is nota simple function ofVS30.Finally, bycomparing thestandard deviations ofthetotal residuals between the observed and predicted values before and after incorporating the fault-type and site-effect (VS30) terms, the change of standard deviation for PGA is 2.3%. In contrast, the PGV standard deviation is significantly decreased by about 11.6%. Evidently, the Model 2 attenuation relationships, especially for PGV, would be better suited for engineering applications.
A New Satellite Image Map of King George Island (South Shetland Islands, Antarctica)

Summary: A new satellite image map in the scale of I: 100 000 of KingGeorge Island (Antarctica) is prcsented. A multi-spectral SPOT satelliteimage mosaic from 1994/2000 forms the base ofthe map. Contour lines werederived from a digital elevation model, which was computed from variousdata sources. Comprehensive meta-information on map accuracy andcompilation is included on the map.Zusammenfassung: Eine neue Satellitenbildkarte im Masstab I: 100 000 furKing George Island (Antarktis) wird vorgestellt. Grundlage der Karte ist einmultispektrales SPOT Satellitenbildmosaik aus dem Jahre 1994/2000. DieHohenlinien wurden aus einem digitalen Gelandemodell abgeleitet, welchesaus verschiedenen Quellen generiert wurde. Umfangreiche Metainfor­mationen zur Kartenerstellung und Genauigkeit wurden in die Karte aufge­nommen. BACKGROUNDThe South Shetland Islands, and in particular King George Is­land, gained historie importance by the first landfall on theAntarctic continent in 1819. Subsequently, sealing and whal­ing ships frequently visited the region due to its rich fauna,sheltered harbours and relatively easy access. Until today,King George Island remains one ofthe most frequented sitesin Antarctica, now with 10 permanent research stations andseveral minor refuges located all around the island. TheChilean air strip on Fildes Peninsula forms a major turntableoflogistic operations for the Antarctica Peninsula region downto the Filchner Ronne area. Moreover, several thousandtourists visit the island each year. At present, five sites ofspecial scientific interest (SSSI) and the first AntarcticSpecially Managed Area (ASMA) are designated on KingGeorge Island to protect ecologically sensible areas. Never­theless the human presence leads to a considerable impact onthe vulnerable ecosystems.As a consequence, probably nowhere else in Antarctica theneed for coordinated approaches in research activities and en­vironmental management is more evident than on KingGeorge Island. This is reflected by recommendation XXVI-6by the Scientific Committee on Antarctic Research (SCAR)adopted at the XXVI'hMeeting ofSCAR in Tokyo, July 2000,
Conference on ‘ The future of animal products in the human diet : health and environmental concerns ’ Symposium 3 : Alternatives to meat The long-term health of vegetarians and vegans

Vegetarians, who do not eat any meat, poultry or fish, constitute a significant minority of the world’s population. Lacto-ovo-vegetarians consume dairy products and/or eggs, whereas vegans do not eat any foods derived wholly or partly from animals. Concerns over the health, environmental and economic consequences of a diet rich in meat and other animal products have focussed attention on those who exclude some or all of these foods from their diet. There has been extensive research into the nutritional adequacy of vegetarian diets, but less is known about the long-term health of vegetarians and vegans. We summarise the main findings from large cross-sectional and prospective cohort studies in western countries with a high proportion of vegetarian participants. Vegetarians have a lower prevalence of overweight and obesity and a lower risk of IHD compared with non-vegetarians from a similar background, whereas the data are equivocal for stroke. For cancer, there is some evidence that the risk for all cancer sites combined is slightly lower in vegetarians than in nonvegetarians, but findings for individual cancer sites are inconclusive. Vegetarians have also been found to have lower risks for diabetes, diverticular disease and eye cataract. Overall mortality is similar for vegetarians and comparable non-vegetarians, but vegetarian groups compare favourably with the general population. The long-term health of vegetarians appears to be generally good, and for some diseases and medical conditions it may be better than that of comparable omnivores. Much more research is needed, particularly on the long-term health of vegans.
Real-Time and Robust Hyperdimensional Classification

Hyper-Dimensional computing (HDC) is a brain-inspired learning approach for efficient and robust learning on today's embedded devices. HDC supports single-pass learning, where it generates a classification model by one-time looking at each training data point. However, the single-pass model provides weak classification accuracy due to model saturation caused by naively accumulating high-dimensional data. Although the retraining model for hundreds of iterations addresses the model saturation and boosts the accuracy, it comes with significant training costs. In this paper, we propose OnlineHD, an adaptive HDC training framework for accurate, efficient, and robust learning. During single-pass training, OnlineHD identifies common patterns and eliminates model saturation. For each data point, OnlineHD updates the model depending on how similar it is to the existing model, instead of naive data accumulation. We expand the OnlineHD framework to support highly-accurate iterative training. We also exploit the holographic distribution of patterns in high-dimensional space to make OnlineHD ultra-robust against possible noise and hardware failure. Our evaluations on a wide range of classification problems show that OnlineHD adaptive training provides comparable classification accuracy to the retrained model while getting all efficiency benefits that a singlepass training provides.
Ceramic Production And Distribution: An Integrated Approach

In the past two decades, the study of ancient trade and exchange has attracted the attention of archaeologists as never before. Despite a long-standing interest in ceramics as cultural markers, the study of the economic role of pottery is still in its infancy. This book presents the archaeologist with approaches for investigating the economics of pottery in pre-industrial societies. The contributors exemplify this in a wide variety of social and economic contexts, ranging from the tribal Iroquois to the imperial Romans and modern peasant societies. They also set out to demonstrate the major techniques for analyzing pottery production and distribution in archaeological record.
