Multiwavelength Monitoring of the Dwarf Seyfert 1 Galaxy NGC 4395. III. Optical Variability and X-Ray/UV/Optical Correlations

We present optical observations of the low-luminosity Seyfert 1 nucleus of NGC 4395, as part of a multiwavelength reverberation-mapping program. Observations were carried out over two nights in 2004 April at Lick, Wise, and Kitt Peak Observatories. We obtained V- and B-band photometry, and spectra over the range 3500-6800 Å. Simultaneous Hubble Space Telescope UV and Chandra X-ray observations are presented in companion papers. Even though NGC 4395 was in an extremely low state of activity, we detect significant continuum variability of 2%-10%, increasing toward shorter wavelengths. The continuum light curves, both spectroscopic and photometric, are qualitatively similar to the simultaneous UV and X-ray light curves. Interband cross-correlations suggest that the optical continuum emission lags behind the UV continuum emission by 24 minutes, and that the optical continuum emission lags behind the X-ray continuum emission by 44 ± 13 minutes, consistent with a reprocessing model for active galactic nucleus emission. There are also hints of Balmer emission lines lagging behind the optical continuum by an amount slightly larger than the emission-line lag detected in the UV. These results are all similar to those of other Seyfert 1 nuclei. The emission-line lag yields a mass measurement of the central black hole, which although not very significant, is consistent with the value derived from the simultaneous UV data.
Expected Returns Across Time Scales ( Work in progress )

This paper studies the role of uctuations in the aggregate price-earning ratio at di¤erent time scales for predicting stock returns and explore the channels through which returns are predicted. Using U.S. quarterly and international monthly data, we nd that cycles in the price-earning ratio are strong and better predictors of future returns at short and intermediate horizons than the aggregate price-earning ratio and several other popular forecasting variables. Moreover, this predictability is economically pro table. The proposed method, based on a wavelet multiscaling method, explicitly accounts for the variations at di¤erent time scales in expected cash-ow growth and expected returns.

A logic approach to the verification and testing of security protocols

Security is an ever important issue in computer networks. Current network security, which is mostly based on (symmetric and asymmetric) key encryption, depends on the soundness of the security protocols as well as the strengths of the encryption algorithms. We propose a logic framework to verify or test the soundness of the security protocols. The logic framework can identify the hidden weaknesses in a protocol. When a verified protocol d esbreak down, this logic framework can also quickly point out the guilty assumptions made in the framework that are responsible for the breakdown of the protocol security. The information is useful in mending the broken protocol.
Patient-Reported Outcome of a Multidisciplinary Pain Management Program, Focusing on Occupational Performance and Satisfaction with Performance

Aim: The aim was to describe the effect of a multidisciplinary pain management program, in terms of patientreported occupational performance and satisfaction with performance.Methods: The study is a retrospective, case series study. Data from interviews documented routinely in patient medical records were used. Interviews were made at introduction, on conclusion and six months after a pain management program. Data from all participants (n=85) introduced during one year, were analysed. The Canadian Occupational Performance Measure (COPM) was used as the main outcome measure.Results: Estimated occupational performance as well as satisfaction with performance improved between measures (occupational performance p<0.001; satisfaction with performance p<0.001). The percentage of participants, who improved two or more points on the COPM ten-point scale between baseline and the 6-month follow up, was 27% for occupational performance and 40% for satisfaction with performance.Conclusion: The findings raise questions regarding what the team might learn from different ways of scrutinizing results; the relevant level of MID in this program; and the overall objective in terms of the proportion of clients who reported a ‘successful’ outcome in occupational performance and satisfaction with performance, based on the identified MID. These questions need to be further analysed and discussed within the professional team.
Social sustainability and a sense of place: harnessing the emotional and sensuous experiences of urban multicultural leisure festivals

ABSTRACT Multicultural leisure festivals have been shown to contribute to sense of place and belonging but the degree to which they accomplish this needs to be examined. There is a growing interest by policy-makers to incorporate sustainability in urban community planning initiatives but its lack of clarity compromises its application for urban community development. Nevertheless, sustainability needs to be acknowledged because of its potential relationship with identity creation, social, political and cultural capital and even happiness and sense of place. This paper examines the role multicultural festivals, as a form of urban multi-ethnic leisure, play in contributing to sense of place and social sustainability. This study draws on data from two multicultural festivals and builds on a framework of emotional and sensuous geographies. It applies the concept, sense of place, to demonstrate how multicultural festival experiences are important components of the everyday leisure experience of migrants.
The Effects of Reading Short Stories in Improving Foreign Language Writing Skills.

This study is an inquiry into the effects of reading short stories in improving foreign language writing skills through Read for Writing model, which is the adaptation of the approach called Talk for Writing (Corbett, 2013). It is a quasi-experimental 13-week field study which was implemented in a primary school. The purpose of this study is to investigate if there is a significant difference both in the pre-post-test writing achievements of students who were taught through the Read for Writing model, and between the experimental group and the control group. Finally, the participants’ views on the model were determined. Both qualitative and quantitative data collection and analysis techniques were designed such as tests for short stories, story assessment control lists, reading and writing syllabuses, lesson plans, an analytic story assessment rubric, and a student’s view questionnaire. The results of the study indicate that the Read for Writing model has a positive effect on students' short story writing skills in terms of language, content, organization, and communicative achievement.

Abstract Background: Emotional prosody comprehension (EPC), the ability to interpret another person's feelings by listening to their tone of voice, is crucial for effective social communication. Previous studies assessing the neural correlates of EPC have found inconsistent results, particularly regarding the involvement of the medial prefrontal cortex (mPFC). It remained unclear whether the involvement of the mPFC is linked to an increased demand in socio-cognitive components of EPC such as mental state attribution and if basic perceptual processing of EPC can be performed without the contribution of this region.
Predicate abstraction and CEGAR for higher-order model checking

Higher-order model checking (more precisely, the model checking of higher-order recursion schemes) has been extensively studied recently, which can automatically decide properties of programs written in the simply-typed λ-calculus with recursion and finite data domains. This paper formalizes predicate abstraction and counterexample-guided abstraction refinement (CEGAR) for higher-order model checking, enabling automatic verification of programs that use infinite data domains such as integers. A prototype verifier for higher-order functional programs based on the formalization has been implemented and tested for several programs.
Participatory design of wearable augmented reality display elements for children at play

This paper presents the findings of a low-fidelity participatory design activity for the design of wearable Augmented Reality (AR) experiences for children at play. The aims of the research were to gain insights into the different types of augmentations children find engaging and useful in different play contexts. The papers contribution is both the method used, and the insights gained from the design session. Using the method outlined the paper, young children were able to successfully understand the concept of augmented reality and communicate their ideas for the design of AR play experiences without first seeing a concrete example of wearable display technology. The children designed for three distinct types of play experience, Constructive play, Role play and Creative play. The children used the design packs assembled by the researchers to express their ideas. These were then coded by four experienced Child Computer Interaction (CCI) researchers to analyze the artifacts created by the children. We identify 10 design themes for AR artifacts in play and discuss the frequency of artifacts found within these themes across the different types of play investigated.
Stable and efficient reduction of substrate model networks using congruence transforms

Parasitic analog-digital noise coupling has been identified as a key issue facing designers of mixed-signal integrated circuits. In particular signal cross talk through the common chip substrate has become increasingly problematic. The paper demonstrates a new methodology for developing simulation, synthesis, and verification models to analyze the global electrical behavior of the non-ideal semiconductor substrate. RC substrate network models, which are generated via a triangular discretization method, are accurately approximated for subsequent analysis by an efficient reduction algorithm. This algorithm utilizes the well-conditioned Lanczos process to formulate Pade approximations of the network port admittance. Congruence transformations are employed to ensure stability, and to create reduced networks which are easily realizable with SPICE-compatible RC elements. For validation, the strategy has been successfully applied to several mixed-signal circuit examples.
The Effect of Information Asymmetries Among Lenders on Syndicated Loan Spreads

We examine the effect information asymmetries among syndicate members on loan spreads. In particular we measure the past relationship of each participant and arranger with the borrower separately by using the previous number of borrowing/lending interactions and the duration of these interactions. Using a sample of 5,842 syndicated loan transactions, we find that when participant banks have an information inferiority in the syndicate they require higher spreads to compensate for this asymmetry. This is amplified when the borrowers are more opaque. On the contrary, the availability of borrower credit ratings significantly reduces information asymmetries and nullifies the impact of information set differences among arrangers and participants on loan spreads. We also provide evidence that the presence of reputable arrangers leads to lower spreads only for those borrowers with potentially fewer asymmetric information problems. For opaque borrowers, mandating a reputable arranger facilitates access to funds available in the syndicated loan market but does not lower loan spreads. JEL classification: D40, F30, G21
ANGERS 2011 Wine Festivals Tourism : How important is Recycling to Attendees ?

Sustainable development and marketing are applied across the tourism spectrum, yet a need exists to make them relevant to specific forms of tourism such as festival tourism. Festivals are available to all groups in a community, offering the most effective setting in which to teach certain ideals. Thus festivals can be great educational settings through which to understand environmental behavior and attitudes. This study established an assessment to measure recycling attitudes, behaviors, and intentions of customers, segmenting festival attendees by gender and age as the basis for selective marketing classification. The results suggest that female and Generation X consumers’ attitudes toward festivals, such as providing recycling bins or stations and utilizing renewable energy, could improve festival attendance, thereby increasing revenue and building a better connection to the local community.
Recycling and Endogenous Cycles

This article investigates the conditions under which deterministic cycles can emerge in a discrete-time model with infinitely lived agents and when the economy is characterized by two sectors producing two perfectly substitutable goods: a virgin good and a recycled one. The occurrence of deterministic fluctuations rests upon the countercyclical behavior of the recycling industry: an increase in present consumption implies a lower future waste activity together with a lower agents' total income, yielding a decline in next period consumption.
Pore pressure and poroelasticity effects in Coulomb stress analysis of earthquake interactions

[1] Pore pressure changes are rigorously included in Coulomb stress calculations for fault interaction studies. These are considered changes under undrained conditions for analyzing very short term postseismic response. The assumption that pore pressure is proportional to fault-normal stress leads to the widely used concept of an effective friction coefficient. We provide an exact expression for undrained fault zone pore pressure changes to evaluate the validity of that concept. A narrow fault zone is considered whose poroelastic parameters are different from those in the surrounding medium, which is assumed to be elastically isotropic. We use conditions for mechanical equilibrium of stress and geometric compatibility of strain to express the effective normal stress change within the fault as a weighted linear combination of mean stress and fault-normal stress changes in the surroundings. Pore pressure changes are determined by fault-normal stress changes when the shear modulus within the fault zone is significantly smaller than in the surroundings but by mean stress changes when the elastic mismatch is small. We also consider an anisotropic fault zone, introducing a Skempton tensor for pore pressure changes. If the anisotropy is extreme, such that fluid pressurization under constant stress would cause expansion only in the fault-normal direction, then the effective friction coefficient concept applies exactly. We finally consider moderately longer timescales than those for undrained response. A sufficiently permeable fault may come to local pressure equilibrium with its surroundings even while that surrounding region may still be undrained, leading to pore pressure change determined by mean stress changes in those surroundings.
The partisan contours of conspiracy theory beliefs

The “conspiracy theories are for losers” argument suggests that out-of-power groups use conspiracy theories to sensitize minds, close ranks, and encourage collective action. Two necessary conditions of this argument are that (1) group members subscribe mostly to conspiracy theories that malign out-groups or bolster their in-group, and (2) group members must recognize whether conspiracy theories emanate from their own group, an opposing group, or are outside of partisan conflict. Using representative survey data from the 2012 Cooperative Congressional Election Study, we show that conspiracy accusations follow the contours of partisan conflict: partisans accuse opposing groups, rather than co-partisans or non-partisans, of conspiring. Using MTurk data, we show that partisans can differentiate between the conspiracy theories coming from members of each party. We suggest that many conspiracy beliefs behave like most partisan attitudes; they follow the contours of partisan conflict and act as calling cards that send clear signals to co-partisans.
Public’s perceived overcrowding risk and their adoption of precautionary actions: a study of holiday travel in China

Abstract The importance of travel risk has been recognized, but only a limited number of studies have been conducted on this risk and the precautionary actions the public may take to manage it during holidays. This study applied the protective action decision model and the protection motivation theory to examine the public’s intent to take precautionary actions during holiday times to handle the risk of overcrowding in China. Our survey showed that efficacy-related attributes of precautionary actions were positively correlated, whereas resource-related attributes were negatively correlated, with the intention to take precautionary measures. Risk perception also significantly influenced the adoption intention, but the amount of variance in the intention to adopt precautionary actions that was motivated by risk perception was lower than that related to efficacy-related attributes. In addition, we found that risk perception mediated the influence of past overcrowding experiences on people’s intention to adopt precautionary measures. Travel frequency, length of time spent away for the holiday, and the number of underage family members involved were significantly correlated with the intention to adopt precautionary actions. Finally, this paper discussed suggestions and implications for travelers, tourist departments, and related stakeholders.
