How Can One Tell When the Housing Market Is Out of Equilibrium

Purpose - One way of detecting departures from equilibrium is by comparing house prices and rents. Here I assess the viability of this approach.Design/methodology - Error-correction models (ECMs) based on price and rent indexes can be used to forecast movements in house prices. The short-term forecasting ability of ECMs is limited though due to the long persistence of departures from equilibrium. ECMs also suffer from the limitation that they do not tell us whether the price-rent ratio is above or below its equilibrium level at any given point in time. To answer this question it is necessary to make cross-section comparisons of prices, rents and user cost (i.e., the cost incurred by owning a house). Findings - A meaningful cross-section comparison requires that prices and rents are quality adjusted. This may require the use of hedonic methods. The equilibrium price-rent ratio (which is derived from the user cost) is difficult to compute since it depends on the expected capital gain. Also, both the actual and equilibrium price-rent ratios differ depending on which segment of the housing market is considered. Originality/value - The housing market, which is prone to booms and busts, can very significantly affect the rest of the economy. Hence it is important that central banks and governments can detect when the housing market is out of equilibrium. I show here how difficult it is to detect such departures.
Particle Filter Based Prognostics of PEM Fuel Cell Under Constant Load

This paper develops an efficient solution towards the prognostics of industrial PEMFC. It involves employment of an efficient multi-energetic model suited for diagnostics and prognostics, developed in Bond Graph framework. The Electrical-Electrochemical (EE) part constitutes the main focus for the problem of prognostics, wherein deviation of the global resistance and limiting current inspires a statistical linear degradation model (DM), under constant current load conditions. The benefits of Particle Filters (PF) is integrated with the BG model derived Analytical Redundancy Relations (ARRs), for prognostics of the electrical-electrochemical (EE) part. The prognostic problem is formulated as the joint state-parameter estimation problem in Particle Filter framework. Using PF algorithms, in probabilistic terms, estimation of State of Health (SOH) is obtained along with the estimation of the associated parameter that influences the rate of degradation. A simplified variance adaptation scheme is employed to ameliorate the accuracy of remaining useful life (RUL) predictions. Influence of variance adaptation on SOH estimation as well as RUL prediction is assessed. It is shown that a proportional type of variance control leads to better accuracy in RUL predictions accompanied with precise confidence bounds. As the degradation data is obtained from a real industrial PEMFC, the economic viability of this approach for prognostics of PEMFC is significantly high.
Measuring the meta and cognitive abilities of air defence operators

Introduction: This study aimed to understand more fully some factors that influence decision confidence and accuracy related to air defence. To investigate the metacognitive abilities of air defence operators a Within-Subjects Confidence-Accuracy (W-S C-A) measure was used. Specifically, therefore, this study investigated the impact of Decision Criticality (DC) and Task Stress (TS) on decision making, measures of confidence, accuracy, and the W-S C-A relation. Personality constructs, workload and situation awareness were also included. Method: Participants were allocated to either a high, moderate or low task stress condition. Each participant then took part in a computer generated air defence scenario where they were required to make various decisions and provide a confidence rating for each of those decisions. Confidence, accuracy and W-S C-A were calculated. Results & Discussion: DC impacted both on decision confidence and accuracy, with low DC increasing confidence in decisions and high DC increasing accuracy in decisions.
RESOURCE DEPENDENCE THEORY 2 . 1 Applicability to Supply Management 2 . 1 . 1 Resource Acquisition at the Core of RDT ’ s Determinants for Organizational Behavior

The relative newness of the field of supply management, in combination with its nature of being an applied one, leads to a lack of valid theoretical foundation. Shook et al. (2009) therefore propose a toolbox for better strategic sourcing founded on well-established theories. This thesis offers such a tool by referring to resource dependence theory (RDT) to develop an innovative perspective on the four critical decision points in supply management; the make-or-buy decision, the selection of a sourcing strategy per category, the establishment of a supply pool, and the negotiation and contracting decision. RDT’s predictions are analyzed based on an extensive literature review. Basically, the aim of any organization, according to RDT, is maximal independence and certainty in an environment that threatens through dependency and uncertainty. The comprehensive informative value of RDT allows for an application of its insights to all four decision points. As a result, improvements and advises for each of the decisions are presented. It is advised to insource the production of critical items if they can only be sourced constrained through dependency or uncertainty. Besides that, the selection of suppliers that are equally powerful or weaker is favored. For the decision towards the establishment of a supply pool and the selection of a sourcing strategy, in particular the insights about relational buyer-supplier approaches to ensure supplies are of great value.

The Post-periapsis Evolution of Galactic Center Source G1: The Second Case of a Resolved Tidal Interaction with a Supermassive Black Hole

We present new adaptive optics (AO) imaging and spectroscopic measurements of Galactic center source G1 from W. M. Keck Observatory. Our goal is to understand its nature and relationship to G2, which is the first example of a spatially resolved object interacting with a supermassive black hole (SMBH). Both objects have been monitored with AO for the past decade (2003–2014) and are comparatively close to the black hole (amin ∼ 200–300 au) on very eccentric orbits (eG1 ∼ 0.99; eG2 ∼ 0.96). While G2 has been tracked before and during periapsis passage (T0 ∼ 2014.2), G1 has been followed since soon after emerging from periapsis (T0 ∼ 2001.3). Our observations of G1 double the previously reported observational time baseline, which improves its orbital parameter determinations. G1's orbital trajectory appears to be in the same plane as that of G2 but with a significantly different argument of periapsis (Δω = 21° ± 4°). This suggests that G1 is an independent object and not part of a gas stream containing G2, as has been proposed. Furthermore, we show for the first time that (1) G1 is extended in the epochs closest to periapsis along the direction of orbital motion, and (2) it becomes significantly smaller over time (450 au in 2004 to less than 170 au in 2009). Based on these observations, G1 appears to be the second example of an object tidally interacting with an SMBH. G1's existence 14 yr after periapsis, along with its compactness in epochs further from the time of periapsis, suggest that this source is stellar in nature.
Alexithymia and Personality in Relation to Social Anxiety in Male Alcohol-Dependent Inpatients

Address for Correspondence/Yaz›flma Adresi: Dr. Cuneyt Evren, Bak›rkoy Ruh Sa¤l›¤› ve Sinir Hastal›klar› E¤itim ve Araflt›rma Hastanesi, Alkol ve Madde Ba¤›ml›l›¤› Araflt›rma Tedavi ve E¤itim Merkezi, ‹stanbul, Turkey E-posta: cuneytevren@yahoo.com Gelifl tarihi: 08.08. 2008 Kabul tarihi: 18.09. 2008 ABSTRACT Objective: The aim of this study was to investigate the determinants of social anxiety symptoms in alcohol dependent inpatients. Method: Participants were 176 consecutively admitted male alcohol dependent inpatients. Patients were investigated with the Liebowitz Social Anxiety Scale (LSAS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Toronto Alexithymia Scale (TAS-20) and Temperament and Character Inventory (TCI). Results: Subscales of LSAS (fear or anxiety and avoidance) were correlated with all the scales, particularly highly correlated with BDI, TAS-20 and “difficulty in identifying feelings” (DIF) and “difficulty in describing feelings” (DDF) subscales of TAS-20. Harm avoidance (HA) showed positive correlation with LSAS subscales, whereas self-directedness (SD) showed negative correlation with these subscales. TAS-20-DIF, HA and cooperativeness (C) subscales were determinants for fear or anxiety subscale of LSAS, whereas HA and TAS-20-DDF were determinants for the avoidance subscale of LSAS. Conclusion: Fear and anxiety subscale and DIF are interrelated, whereas avoidance subscale and DDF are interrelated among male alcohol-dependent inpatients. Also HA seems to be an important predictor for both subscales. Gender specific aspects and long-term stability of these relationships need further inquiry.

Study on vibration of the offshore large-scale wind turbine blade under fluid structure interaction at different wind speeds

The research object is based on the 1.5 MW large offshore wind turbine blade. A theoretical model for describing the geometrical non-linearity vibration behavior under the condition of fluid structure interaction (FSI) was established, the entity modeling of the wind turbine blade was achieved by using Pro/E, and the numerical simulation under unidirectional FSI (UFSI) and bidirectional FSI (BFSI) was carried out at different wind speeds by ANSYS and CFX softwares. The results indicate that the high pressure region and low pressure region respectively appear on the windward side and the leeward side of the blade, and the strength of wind pressure distribution under BFSI is lower than the one under UFSI. It is also found that the maximum brandish displacement locates in the blade tip and the maximum Mises stress occurs in the middle of blade at different wind speeds. Furthermore, the effect of BFSI on the wind blade vibration is much more obvious with the increase of wind speed. Finally, compared with the amplitude calculated by UFSI, the analytical method of BFSI truly reveals the aeroelastic characteristics of the blade under complex offshore wind conditions.
Osserman Lightlike Hypersurfaces on a Foliated Class of Lorentzian Manifolds

This paper deals with a family of Osserman lightlike hypersurfaces $(M_u)$ of a class of Lorentzian manifolds $\bar{M}$ such that its each null normal vector is defined on some open subset of $\bar{M}$ around $M_u$. We prove that a totally umbilical family of lightlike hypersurfaces of a connected Lorentzian pointwise Osserman manifold of constant curvature is locally Einstein and pointwise ${\cal F}-$Osserman, where our foliation approach provides the required algebraic symmetries of the induced curvature tensor. Also we prove two new characterization theorems for the family of Osserman lightlike hypersurfaces, supported by a physical example of Osserman lightlike hypersurfaces of the Schwarzschild spacetime.
Visible-blind ultraviolet photodetector based on double heterojunction of n-ZnO/insulator-MgO/p-Si

Exploiting a double heterojunction of n-ZnO/insulator-MgO∕p-Si grown by molecular beam epitaxy, a visible-blind ultraviolet (UV) photodetector has been fabricated. The photodetector shows a rectification ratio of ∼104 at ±2V and a dark current of 0.5nA at a reverse bias of −2V.The photoresponse spectrum indicates a visible-blind UV detectivity of our devices with a sharp cut off at the wavelength of 378nm and a high UV/visible rejection ratio. The key role of the middle insulating MgO layer, as a barrier layer for minority carrier transport, has been demonstrated.
Inductive Filtering Converter in HVDC Light Systems

The Voltage source converter (VSC) based HVDC system is a relatively new technology for low and medium power transmission which can be connected to weak or even passive AC networks and is capable of supplying or absorbing reactive power according to the system operating conditions. The main switching component of the VSC is a high power high frequency static switch. A new voltage source inductive filtering converter (VSIFC) for HVDC Light transmission system which is mainly composed of the inductive filtering (IF) transformer and the related full-tuned (FT) branches with the commutating function for the self commutated converter. This paper concerns on the technical feasibility on the application of VSIFC in HVDC-Light systems. A typical test system for the proposed VSIFC-based HVDC-Light transmission is established in MATLAB/SIMULINK. Harmonic filters are installed on the PCC. The coupling transformer not only provides the suitable line-voltage for self-commutated converter, but also utilizes its leakage reactance efficiently to exchange active and reactive power between VSC and power system. It is worth to remark that although there is a special commutating reactor for VSC station, with the consideration that provide the suitable linevoltage for the operation of VSC station and prevent the 3-time harmonic currents from flowing into PCC, the coupling transformer is necessary to be installed.

E-exhibition towards international trade base on knowledge management

In recent years, the total number of traditional exhibition in developed countries show a decline, exhibitors are dropped because more of them use network technology to carry out on-line international trade, display products and the exchange of information. E-exhibition is to flourish which provide low cost and all-day exhibition to international trade of Medium-Sized Enterprise (SME), but the current only human-readable web content hindered E-exhibition development, we propose a kind of E-exhibition solution based on Semantic Web making web content machine-readable so that international trade can be more easily analyzed by software agents and shared among Web Services which can represent explicitly the core competitiveness of SME. Then, a new knowledge management methodology for E-exhibition of SME which including product, process, technology, services and application domain sub ontology based on semantics web is given. Furthermore, we propose E-exhibition logical view using Semantic Web, select the consumer goods as the application domain, and set up an E-exhibition platform of SME. In the end, consumer goods ontology architecture is give and a case study is shown, which proved that semantics web provide at least the infrastructure to build reusable structures among communities of E-exhibition for SME.
The effects of income imputation on microanalyses: evidence from the European Community Household Panel

Summary. Social surveys are usually affected by item and unit non‐response. Since it is unlikely that a sample of respondents is a random sample, social scientists should take the missing data problem into account in their empirical analyses. Typically, survey methodologists try to simplify the work of data users by ‘completing’ the data, filling the missing variables through imputation. The aim of the paper is to give data users some guidelines on how to assess the effects of imputation on their microlevel analyses. We focus attention on the potential bias that is caused by imputation in the analysis of income variables, using the European Community Household Panel as an illustration.
Two finite-difference time-domain methods incorporated with memristor

Two finite-difference time-domain (FDTD) methods incorporated with memristor are presented. The update equations are derived based on Maxwell's equations, and the physical model is given by Hewlett-Packard (HP) lab. The first method is derived by calculating the memristance directly while the second method is derived by the relationship between electric charge and flux. Numerical results are given to discuss the accuracy, efficiency and stability of both proposed methods.
Flexible reproductive timing can buffer reproductive success of Pygoscelis spp. penguins in the Antarctic Peninsula region

ABSTRACT: Varying the timing of reproduction in response to local environmental conditions is akey factor influencing reproductive success. We used 19 yr (1991 to 2009) of data on breedingchronology and reproductive success of Adelie penguins Pygoscelis adeliae and gentoo penguins P. papua at King George Island, Antarctica to compare clutch initiation dates (CIDs), hatch rates,and creche rates at population and individual levels. The CIDs of both species occurred earlierwith warmer October temperatures, but gentoo penguins adjusted CIDs twice as much per °C oftemperature as Adelie penguins. Gentoo penguins also exhibited lower variances in hatch andcreche rates than Adelie penguins, suggesting that greater ability to respond to ambient condi-tions can buffer reproductive success. Mixed-effects models revealed that individual- and year-specific random effects on the overall population mean best accounted for observed variation inCIDs, with some individuals routinely breeding earlier than others. However, individual differ-ences in the relative timing of breeding provided no advantage for long-term reproductive suc-cess. The results suggest that, among gentoo and Adelie penguins, plasticity in CIDs with respectto environmental conditions is primarily a population-level rather than an individual-levelresponse. Energetic constraints of contrasting migratory and fasting behaviors likely contribute tothe different abilities to respond to warming spring temperatures. Overall, larger responses ofgentoo penguin CIDs to October temperature and lower variability in reproductive success,despite reduced reproductive success with delayed breeding, suggests that gentoo penguins arebetter equipped than Adelie penguins to adjust to rapid warming in the Antarctic Peninsulaecosystem.KEY WORDS: Phenology · Adelie · Gentoo · Climate change · Migrant

Alzheimer’s disease (AD) is the world’s most common form of dementia, affecting over 44 million people worldwide. AD is a neurodegenerative disease, characterized by extracellular deposition of amyloid-β peptide and the intracellular formation of neurofibrillary tangles. During the last few years, neuroinflammation has been pointed out as an important component of AD pathology and several inflammation-related genes have already been associated with AD. Elevated levels of inflammatory cytokines and interleukins have been found in AD patients. Overexpression of these mediators is critical for the onset of the inflammatory process and mediates the expression of inflammation-related genes. Here we performed a case-control association study to evaluate the association between TLR6, TLR2, NEK7, IL-18, IL-1B, NLRP10, and COL4A1 genetic polymorphisms, and AD susceptibility, and association with other AD cognitive variables. A total of 152 AD patients and 120 controls were included in the study. All the polymorphisms were genotyped using the Sequenom MassARRAY iPLEX Platform. rs6531669 (TLR6) was found to be associated with AD susceptibility, age of onset, and MMSE; rs13105517 (TLR2) was found to be associated with AD susceptibility, and MMSE; rs9919613 (NLRP10) was found to be associated with AD susceptibility, age of onset, and disease severity; rs1143643 (Il-1B) was found to be associated with age of onset, and disease severity; rs613430 (COL4A1) was found to be associated with disease severity. In conclusion, our study suggests that TLR6, TLR2 and NLRP10 are candidate genes for AD pathogenesis, and that these genes and IL-1B and COL4A1 are associated with AD onset and other cognitive variables. Key-words: Alzheimer’s disease, inflammation, TLR2, TLR6, IL-1B, NLRP10, COL4A1.
Do covers influence the capture efficiency of pitfall traps

Pitfall traps are widely used in terrestrial ecology to capture ground-dwelling arthropods. In order to determine the effect of covers placed over pitfall traps on their efficiency at capturing of spiders, carabid beetles and ants, four types of pitfall trap were sunk into the ground at dry grassland sites: three pitfall traps were not covered, three were covered with white, three with green and three with black plastic covers. The total catch was 9,364 spiders, 4,352 carabid beetles and 4,157 ants. The distribution of species of spiders and carabid beetles, and the total catch of spiders, carabid beetles and ants did not differ significantly among the four types of trap. Therefore, covers do not appear to affect the capture efficiency of pitfall traps.
TDOA-Based Acoustic Direction Finding

This chapter focuses on estimating the azimuth and elevation angles of a sound emitter based on timedifference-of-arrival (TDOA) measurements using an array of acoustic sensors. The TDOA-based direction-finding problem is appropriate because in a range of scenarios the source only emits a transient signal and TDOA measurements provide a simple method of finding the direction of the received signal. Given the measurement of TDOA, three methods for calculating the actual bearing of an acoustic source are considered—algebraic calculations based on trigonometric functions, linear least squares, and nonlinear least squares—and these results are also compared with the Cramer-Rao lower bound (CRLB). In this chapter, a comprehensive analysis of TDOA-based direction-finding methods is presented with regard to different application conditions, while their estimation performances are analysed with both simulation and field experimental results produced by 3-D microphone array.
Experimental Hypersensitivity Pneumonitis Induced by Fusarium kyushuense in Mice

Experimental Hypersensitivity Pneumonitis Induced by Fusarium kyushuense in Mice: Koichi Harada, et al. Department of Hygiene, Kumamoto University School of Medicine—Arecently described Fusarium species, Fusarium kyushuense, was isolated from dead leaves of egg plant in a greenhouse where a female farmer who developed hypersensitivity pneumonitis (HP) with progressing lung lesions had been working. The freeze dried fungus was exposed to specific pathogen‐free, 6‐week‐old female C57Black/6J mice under light ether anesthesia. Each mouse received 40 pi of the suspended fungal solution by dropping it onto its nostrils in 5 consecutive days a week for 4 wk. The control group received 40 μl of 0.1 M sterilized phosphate buffered saline. The mice were killed on the 4th day after the final exposure. The lung indices increased dose dependently in the fungus exposed mice groups. The specific IgG anti‐Fkyushuense levels in sera of the high dose group were significantly higher than in the control group (P <0.05 by Ryan's multiple comparison test). Histologically, the lungs of both low and high dose groups showed signs of atelectasis with granulomatous lesions containing multinuclear giant cells and activated macrophages. This is the first report that mice developed HP induced by repeated exposure to freeze dried F. kyushuense.
