Is trust an ambiguous rather than a risky decision

According to an early approach, the decision to trust in the one-shot anonymous trust game is intuitively tantamount to a risky decision: the willingness to bet on the reciprocation of my investment. In a seminal study, Eckel and Wilson (2004) explored the correlation between risk attitudes (as elicited through a Holt and Laury mechanism) and the behavior of investors in the trust game. They found no correlation: trust decision cannot be viewed as a risky decision. However, since the probabilities of possible returns are unknown, we argue that trust behavior may correlate more specifically with ambiguity aversion rather than with risk aversion. We therefore modified Eckel and Wilson's experimental procedure in order to investigate the question as to whether trust is an ambiguous decision. We extended Holt and Laury switching-point elicitation mechanism between risky lotteries to ambiguous lotteries as Chrakravarty and Roy (2009) did. We then ran an experimental session including a standard one shot anonymous trust game (OSG). We found significant negative correlations between aversion to ambiguity and behavior in OSG. This result is a plea in favor of a decision-theoretical analogy between choices in ambiguous lotteries and trust-games.
On Teaching Software Architecture and Design

This paper describes a sophomore/junior level course on software architecture and design. The course covers general principles of system requirements and conceptual models, not just “programming skills”. Key components of the course include use of UML (Unified Modeling Language) for description of system models, use of CASE (computer aided software engineering) tools for software modeling and development, GUI (graphical user interface) design, case studies of several kinds of software applications, writing skills, and programming assignments. Example systems include typical business data management software, soft real-time control of devices, direct manipulation visual models, and distributed computing. Programming is done primarily using Java, with some work using C++. With the foundation of object oriented structure, there is little difficulty in using the equivalent subset of C++. The course is offered within a track of software engineering (within a computer science/ information systems curricula); however, the course is also taken by electrical and computer engineers and some students from other engineering disciplines. The course is prerequisite to our capstone project course on software engineering. The architecture course does not cover general software engineering topics (such as testing, estimation, and management), but it does provide students in the capstone course with foundation skills for software design and development. This type of architecture and design course should be an appropriate second level course for engineers with a minor emphasis of software.
Consumer willingness-to-pay for GM food products in Italy.

This paper evaluates consumer willingness-to-pay (WTP) for food products obtained through the application of biotechnology using data collected from a c onsumer survey in Italy in 1999. Survey results show that consumers have a low degree of knowledge of the issue, but an overall positive attitude towards genetically modified (GM) foods. Estimation results of an ordered probit model suggest that WTP is mainly affected by income and information.
THE PATH FROM BIM TO A 3D INDOOR FRAMEWORK – A REQUIREMENT ANALYSIS

Abstract. Building Information Modelling is a new technology and tool for researchers in Architecture/Construction/Engineering (ACE) fields, and it is designed to organise the collaboration between different parties and manage all types of information regarding buildings. A standardized data model of BIM named Industry Foundation Classes (IFC) has been proposed to describe building & construction related information and facilitate the interoperability of building data. As IFC contains plenty of building information, further spatial analysis can be applied in geographical information system (GIS) with these information. Current research has mainly discussed the requirements about data translation from BIM to GIS. However, more specific requirements on the functionalities of a generic 3D indoor framework need to be considered with IFC data. Although this research is in the initial stage, we investigate the use of BIM IFC for the 3D indoor framework, especially on the data translation from IFC to the framework, data management in the framework and IFC data for 3D spatial analysis. Requirements are analysed in four aspects: 1) automation of indoor vector map generation; 2) data management for the framework; 3) environmental analysis of the framework; and 4) safety analysis of the framework. According to these requirements, new modules need to be developed. In the future, based on IFC data we will conduct tests of data transformation, design a data model for the 3D indoor framework and develop a prototype to demonstrate the planned spatial analysis functionalities.
The Role of Fiscal Policy in a Monetary Union: Are National Automatic Stabilizers Effective?

We assess the role of national fiscal policies, as automatic stabilizers, within a monetary union. We use a two-country New Keynesian DSGE model, incorporating non-Ricardian consumers and a home bias in national consumption. Fiscal policy directly stabilizes non-Ricardian agents' consumption. By doing so it contributes to the reduction in the volatility of variables such as output, wage inflation, and real interest rates. Our analysis of country-specific shocks does not suggest potential inter-country conflicts (as long as policies are constrained within the automatic stabilizers framework). However, we detect a potential conflict between the two consumer groups, because fiscal policy may raise optimizing agents' consumption volatility.
Towards a Heuristic Model for Usable and Secure Online Banking

The main purpose of this paper is to propose a heuristic model for usable and secure online banking. The model is based on identified heuristics that contribute to the design of usable security in the context of online banking security. Little research has focused on the balance between usability and security in online banking authentication mechanisms when evaluating the effectiveness of security systems. Nielsen’s ten usability principles are still important in designing usable secure systems, as indicated by the analysis of heuristics developed from recent studies. Online banking users are vulnerable to numerous old and new online security threats that target this group of users. An investigation into the usability of aspects of security design can benefit both online bankers and users in fostering a secure and usable banking environment. In this paper, we report on a work in progress that intends to develop a heuristic model for usable online banking security design. Going forward we intend to refine the model by collecting survey data from online banking users in South Africa and interviews with bank security personnel.
STUDY ON CONSTRUCTION OF 3D BUILDING BASED ON UAV IMAGES

Based on the characteristics of Unmanned Aerial Vehicle (UAV) system for low altitude aerial photogrammetry and the need of three dimensional (3D)city modeling, a method of fast 3D building modeling using the images from UAV carrying four-combined camera is studied. Firstly, by contrasting and analyzing the mosaic structures of the existing four-combined cameras, a new type of four-combined camera with special design of overlap images is designed, which improves the self-calibration function to achieve the high precision imaging by automatically eliminating the error of machinery deformation and the time lag with every exposure, and further reduce the weight of the imaging system. Secondly, several-angle images including vertical images and oblique images gotten by the UAV system are used for the detail measure of building surfaces and the texture extraction. Finally, two tests that are aerial photography with large scale mapping of 1:1000 and 3D building construction in Shandong University of Science and Technology and aerial photography with large scale mapping of 1:500 and 3D building construction in Henan University of Urban Construction, provide authentication model for construction of 3D building based on combined wide-angle camera images from UAV system. It is demonstrated that the UAV system for low altitude aerial photogrammetry can be used in the construction of 3D building production, and the technology solution in this paper offers a new, fast and technical plan for the 3D expression of the city landscape, fine modeling and visualization. * Corresponding author.
CO2 vs. Salmon: Complementary Policies In Wheat Transportation In The Pacific Northwest?

Global climate change is one of the most debated environmental issues of the 21st century. Carbon dioxide (CO2) is the principal contributor to climate change. Higher levels of CO2 concentrations are primarily the result of burning of fossil fuels such as petroleum, coal and natural gas. Simultaneously, salmon populations are now being threatened and endangered. One technique to restore the salmon is the potential drawdown of the Snake River in Washington State. But, a paradox arises because this effort may increase the CO2 production by trucks and rail as barge transportation is stopped on the river. This paper uses wheat and barley transportation, the largest user of barge, to examine the impact on energy consumption and associated CO2 production if the river is breached and barge transportation ceases. A GIS-GAMS transportation model examines the pre and post breaching least cost wheat flows for the producer. Significant increases in rail movements are seen, with some increases in truck in a feeder role to the rail. The relative modal energy intensity coefficients affect the energy consumed. Overall results indicate that the paradox continues with breaching causing some increase in CO2 levels, especially for the barley movements (41%) and overall (1.61%), while offering the possibility of some perceived benefit to the endangered salmon stocks.
Habitat-based spatial models of cetacean density in the eastern Pacific Ocean

Many users of the marine environment (e.g. military, seismic researchers, fisheries) conduct activities that can potentially harm cetaceans. In the USA, Environmental Assessments or Environmental Impact Statements evaluating potential impacts are required, and these must include information on the expected number of cetaceans in specific areas where activities will occur. Typically, however, such information is only available for broad geographic regions, e.g. the entire West Coast of the United States. We present species−habitat models that estimate finer scale cetacean densities within the eastern Pacific Ocean. The models were developed and validated for 22 species or species groups, based on 15 large-scale shipboard cetacean and ecosystem assessment surveys conducted in the temperate and tropical eastern Pacific during the period from 1986 to 2006. Model development included consideration of different modeling frameworks, spatial and temporal resolutions of input variables, and spatial interpolation techniques. For the final models, expected group encounter rate and group size were modeled separately, using generalized additive models, as functions of environmental predictors, including bathymetry, distance to shore or isobaths, sea surface temperature (SST), variance in SST, salinity, chlorophyll, and mixed-layer depth. Model selection was performed using cross-validation on novel data. Smoothed maps of species density (and variance therein) were created from the final models for the California Current Ecosystem and eastern tropical Pacific Ocean. Model results were integrated into a web-interface that allows end-users to estimate densities for specified areas and provides fine-scale information for marine mammal assessments, monitoring, and mitigation.
The formation and growth of ultrafine particles in two contrasting environments: a case study

Abstract. Formation of ultrafine particles and their subsequent growth have been examined during new particle formation (NPF) events in two contrasting environments under varying ambient conditions, one for a tropical semi-urban coastal station, Trivandrum, and the other for a high-altitude free-tropospheric Himalayan location, Hanle. At Trivandrum, NPF bursts took place in the late evening/night hours, whereas at Hanle the burst was a daytime event. During the nucleation period, the total number concentration reached levels as high as ~ 15 900 cm−3 at Trivandrum, whereas at Hanle, the total number concentration was ~ 2700 cm−3, indicating the abundant availability of precursors at Trivandrum and the pristine nature of Hanle. A sharp decrease was associated with NPF for the geometric mean diameter of the size distribution, and a large increase in the concentration of the particles in the nucleation regime (Dp
Hybrid Wind Solar Energy System: Newconverter design

The aim of this project is to design and simulate a hybrid wind-solar energy system: a new rectifier stage topology. Renewable sources are becoming more important than ever as a result of concern. This project presents a new system configuration of the front-end rectifier stage for a hybrid wind/photovoltaic energy system. This configuration allows the two sources to supply the load separately or simultaneously depending on the availability of the wind and solar energy sources. By the inherent nature of this CUK-SEPIC fused converter, additional input filters are not necessary to filter out high frequency harmonics. The fused design of CUK and SEPIC in the rectifier stage also allows Maximum Power Point Tracking (MPPT) to be used to extract maximum power from the wind and sun when it is available. The obtained dc voltage sources depending on the availability are boosted to obtain maximum voltage and inverted by a three phase inverter to supply a three phase load. In case any excess voltage obtained can be stored using an electrostatic capacitor and may be also given to the grid. The simulation results show the efficiency of the CUK and SEPIC integration than the other dc boosters.

- The Internet of Things is the interconnection via the Internet of computing devices embedded in everyday objects, enabling them to send and receive data. The chess robot is an innovative implementation of remote game playing platform for chess enthusiasts. The primary motive of building the chess robot was to provide a physical, mobile and economical platform to chess players to play chess in real time against opponents anywhere in the world so long as there is an internet connection. Two complete chess robots have been designed for analysing and testing the multiplayer interface between two players. They have been constructed within a highly constrained budget of INR 8500 (approx. 130$). The full-length paper discusses the various considerations and underlying principles that have been incorporated in the development of the chess bots. The paper also draws light on the choice of the components that have been included in the chess bots and the specific rationale behind choosing the same. An exhaustive flowchart explains the various steps involved in replicating a certain player’s move on the opponent’s chess board. In conclusion, the several problems encountered during the assembly and development of chess engine of the chess bots have been put before the readers.
ForestPlots.net – managing permanent plot information across the tropics

Compiling and analysing tropical forests plot data has provided key insights into the population and carbon dynamics of tropical forests. ForestPlots.net is a web application developed to provide a secure online environment for long-term forest plot data for researchers worldwide working within international networks such as RAINFOR, AFRITRON, and TROBIT, allowing scientists to manage, analyse, and compare their data to other sites. The underlying database (GIVD ID 00-00-001) in ForestPlots.net is a relational database which utilizes more than 50 tables to store plot location, individual taxonomic information and repeated diameter measurements for trees. Currently the database holds information on more than 800 plots from 27 countries with approximately half a million tropical trees tagged, measured, and monitored through time. The web application allows users, depending on their permission level, to view, edit, upload and download data of the plots they have access to. A novel feature of the database is the query library which produces outputs for the selected plots on biomass, basal area, wood productivity, and stem dynamics.
Mona: Secure Multi-Owner Data Sharing for Dynamic Groups in the Cloud

In this paper, we present a secure multi owner data sharing scheme for dynamic groups in the cloud computing. By leveraging on group signature and dynamic broadcast encryption techniques, any cloud user can anonymously share data with others. In this propose a new model for Sharing Secure Data in the Cloud computing for the Multiuser Groups. In this one of the biggest concern with cloud data storage is that of data integrity verification at untreated servers. To preserve data privacy, the basic solution is to encrypt data files, and then upload the encrypted data into the cloud. To resolve this problem recently the best efficient method MONA presented for secured multi owner data sharing in however we identified some limitations in that same approach in terms of reliability and scalability. Hence in this paper we are further extending the basic MONA by adding the reliability and as well as improving the scalability by increasing the number of group managers dynamically.
Research and Application of Geographic Ontology Modeling Method Based on OWL

We studied characteristics of geographic ontology which are different from the traditional ontology in detail. Based on detailed analysis of the basic theory, ontology construction method and the basic principles, we discussed the method of the basic attributes of geographic ontology in the expression of geographical objects with complex spatial relationship. We researched on the ontology modeling language based on OWL in the expression of geographic ontology, we introduced the part-whole theory, topology and location theory into OWL modeling primitives to solve geographic object expression between spatial relationships, and we create a geographic ontology based on the existing spatial data which are verified based on the improved OWL.
Modelica Delft-Tyre Interface

The TNO Delft-Tyre is a renowned model for the pneumatic tire in the automotive industry based upon the famous Magic Formula first introduced by Bakker et.al. in the late eighties [1]. The name Magic Formula seems to appear first at the 1 Delft colloquium on tires four years later [2]. The Magic Formulae themselves have evolved greatly during the last two decades with contributions from a wide variety of companies and researchers. The Magic Formula is widely used in the automotive (and gaming) industry because of its ease of use to represent the complicated tire characteristics. TNO has marketed the Magic Formula tire model as Delft-Tyre and implemented the dynamic forces and moments computation routines, including the extension of SWIFT [3], in a variety of multibody simulation packages, like ADAMS and DADS and general purpose simulation software Simulink ii . Modelon has in close cooperation with TNO by means of extensive benchmarks implemented the MF-Tyre/MF-Swift in Modelica. This paper presents the work conducted to implement the TNO tire models in Modelica which now is available as a commercial library in Dymola.
Compact Broadband Bandpass Filter on Quarter-Mode Substrate Integrated Waveguide Loaded with CRLH Interdigital Slots

A compact broadband bandpasslter (BPF) on Composite right/left-hande (CRLH) Quarter-Mode Substrate Integrated Waveguide (QMSIW) is presented and analyzed in this paper. A size reduction is implemented by etching the CRLH interdigital slots (CRLH-IS) in the compact QMSIW cavity to introduce a lower resonant frequency less than that of the QMSIW. The inuence of the rotation angle of the CRLH-IS on the frequency response of the CRLH QMSIW BPF is analyzed, and the optimal rotation angle is used to implement a BPF with good out-band rejection. The proposed CRLH QMSIW shows the characteristics of low quality factor and high coupling coefficient that make it a good solution to design a broadband bandpasslter. The measured insertion loss is less than 1.8 dB at 4.43 GHz with a fractional bandwidth (FBW) of around 22%. The measured results agree well with the simulated ones.

Photoprotective substances in Antarctic macroalgae and their variation with respect to depth distribution, different tissues and developmental stages

In this study the distribution pattern of UV-absorbing mycosporine-like amino acids (MAAs) was identified and quantified in Antarctic macroalgae and correlated with habitat as well as with the radiation climate in air and under water. In addition, specific amounts of MAAs from selected species collected at different depths, from different parts of the thallus and developmental stages were investigated. Seven different MAAs were detected in 17 out of 28 red algal species, whereas in all brown and 2 green algal species only traces of MAAs were found. In the green alga Prasiola crispa ssp. antarctica a high concentration of an unknown UV-absorbing substance with an absorption maximum at 324 nm was detected. MAA content was negatively correlated with water depth. Higher concentrations of UV-absorbing substances were found in the marginal tissues of thalli than in the basal parts. Tetrasporophytes and gametophytes exhibited similar MAA values. After transplantation from deep to shallow water, the MAA content remained unchanged for 8 d after transplantation. The data presented indicate 3 physiologically different groups of algae in terms of MAA values: (1) species with no capability for MAA biosynthesis; (2) species with a basic MAA con- centration which is adjusted relative to changes in environmental radiation; (3) species with a con- stant relatively high MAA composition and concentration irrespective of environmental conditions.
Characterization of Student’s T- Distribution with Some Application to Finance

The distributional form of the returns on the underlying assets plays a key role in finance under valuation theories for derivative securities. Among them, Student t-distributions are generally applied in financial studies as heavy-tailed substitute to the normal distribution. Therefore, distributions of logarithmic asset returns can often be fitted extremely well using Student t-distribution with degree of freedom, such that . The aim of this paper is to investigate the characterization behavior of Student t-distributions and its related properties into finance which are based on computational aspects using Mathematica. Furthermore, convolution, infinity divisibility and self-decomposability properties of Levy-Student process are considered as background to the option pricing. Finally, applications of modeling high frequency price returns are discussed. Keywords: Characterization behavior, degree of freedom, heavy-tail, Levy-Student process
