Hedonic Wage Equilibrium: Theory, Evidence and Policy

We examine theoretically and empirically the properties of the equilibrium wage function and its implications for policy. Our emphasis is on how the researcher approaches economic and policy questions when there is labor market heterogeneity leading to a set of wages. We focus on the application where hedonic models have been most successful at clarifying policy relevant outcomes and policy effects, that of the wage premia for fatal injury risk. Estimates of the overall hedonic locus we discuss imply the so-called value of a statistical life (VSL) that is useful as the benefit value in a cost-effectiveness calculation of government programs to enhance personal safety. Additional econometric results described are the multiple dimensions of heterogeneity in VSL, including by age and consumption plans, the latent trait that affects wages and job safety setting choice, and family income. Simulations of hedonic market outcomes are also valuable research tools. To demonstrate the additional usefulness of giving detail to the underlying structure we not only develop the issue of welfare comparisons theoretically but also illustrate how numerical simulations of the underlying structure can also be informative. Using a reasonable set of primitives we see that job safety regulations are much more limited in their potential for improving workplace safety efficiently compared to mandatory injury insurance with experience rated premiums. The simulations reveal how regulations incent some workers to take more dangerous jobs, while workers’ compensation insurance does not (or less so).
EQUIDISTRIBUTION OF RATIONAL MATRICES IN THEIR CONJUGACY CLASSES

Let G be a connected simply connected almost Q-simple algebraic group with G := G(R) non-compact and Γ ⊂ GQ a cocompact congruence subgroup. For any homogeneous manifold x0H ⊂ Γ\G of finite volume, and a ∈ GQ, we show that the Hecke orbit Ta(x0H) is equidistributed on Γ\G as deg(a) → ∞, provided H is a non-compact commutative reductive subgroup of G. As a corollary, we generalize the equidistribution result of Hecke points ([COU], [EO1]) to homogeneous spaces G/H . As a concrete application, we describe the equidistribution result in the rational matrices with a given characteristic polynomial.
Are Professors Worth It?

A substantial share of university instruction happens in tutorial sessions—small group instruction given parallel to lectures. We study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial groups. We find this to be largely not the case. Academic rank is unrelated to students’ current and future performance and only weakly positively related to students’ course evaluations. Building on these results, we discuss different staffing scenarios that show that universities can substantially reduce costs by increasingly relying on lower-ranked instructors for tutorial teaching.
FALSE POSITIVE TROPONIN – A TRUE PROBLEM LA@NO POZITIVNI TROPONIN – ISTINIT PROBLEM

Prof. dr Goran Kora}evi} Clinic for Cardiovascular Diseases Clinical Centre Ni{ Bul. Dr. Zorana \in|i}a 48 18000 Ni{, Serbia e-mail: gkoracevicayahoo.com Summary: Cardiac troponins have a crucial role in diagnosing acute myocardial infarction, but have been considered by some authors to have a high false positive rate. Such opinions may decrease the confidence in troponin with important clinical consequences. The aim of the paper is to analyze three different meanings of the phrase »false positive troponin«: A) analytic (technical) false positive, with no real myocardial damage; B) false positive considering AMI: cardiac injury is present, but there is no AMI; C) false positive considering CAD: there is myocardial damage, but no CAD. The most frequent and the most important source of misunderstanding is the confusion between aspects A) and B). Namely, there has been a relatively small percentage of false positive troponin elevations due to analytic reasons. On the contrary, there has been a re latively large percentage of »false positive« results in patients with myocardial necrosis due to causes other than AMI; for them – instead of »FP troponin elevation« – another phrase ought to be used, e.g., »non-AMI troponin elevation« until the etiopathogenesis in an individual patient is recognized. The phrase »false positive troponin« should be restricted to the artificial increase in troponin due to preanalytic and analytic reasons. By doing so, we may decrease the degree of confusion about troponin and increase the confidence in this highly specific marker of myocardial injury. The possibility of an analytic false positive result should always be kept in mind when one interprets elevated troponin.
BeBeC-2014-16 1 HIGH-RESOLUTION FLY-OVER BEAMFORMING USING A PRACTICAL ARRAY

In a previous paper presented at the AIAA 1012 Aeroacoustics Conference, the authors described a commercially available fly-over beamforming system based on a small practical 108-element array with 12 metre diameter designed for quick deployment on a concrete runway. However, the resolution at frequencies below 700 Hz was not sufficient to provide useful noise source identification and quantification. The present paper describes an extended 135-element array with 29 metre diameter, designed for frequencies down to 300 Hz, while still supporting quick deployment on a runway, and it analyzes the results from a series of measurements taken in November 2011 at Taiki Aerospace Research Field, Taiki, Hokkaido, Japan. As in the previous paper, the aircraft under test was a business jet type MU300 from Mitsubishi Heavy Industries. For comparison with engine sound power estimates from fly-over measurements, a set of array measurements was performed on the right engine with the aircraft fixed on the ground. Sound power spectra show good agreement between fly-over and ground-based measurements with comparable engine load conditions.
Incorporation of Ibuprofen into SBA-15 ; Drug Loading and Release Properties

The development of mesoporous materials like SBA-15 offers new possibilities for incorporating biological agents into silica structures and controlling the release kinetics from the matrix due to its well-arranged pore architecture. These materials show significant mesoporosity associated with their hexagonally organized channels, narrow pore size distribution, and large surface area. Ibuprofen was selected as a model molecule since it is a well-documented and highly used anti-inflammatory drug. Furthermore, its molecular size (about 1.0 nm) is suitable for incorporation into the mesopores of the SBA-15 material (pore size is 4.6-10 nm). Mesoporous silica SBA15 was prepared to evaluate its application as a carrier for Ibuprofen drug delivery. The loaded SBA-15 was characterized by thermo gravimeter analysis, X-ray diffraction, scanning electron microscopy, and N2 adsorption/desorption isotherm. The incorporation procedure resulted in a significant improvement of the amount of Ibuprofen loaded into SBA-15, and in vitro drug release was investigated. _____________________________________________________________________________________________________________
EFFECTIVE TOPOLOGY-AWARE PEER SELECTION IN UNSTRUCTURED PEER-TO-PEER SYSTEMS

Peer-to-Peer systems form logical overlay networks on top of the Internet. Essentially, peers randomly choose logical neighbours without any knowledge about underlying physical topology. This may cause inefficient communications among peers. This topology mismatch problem may result in poor performance and scalability for Peer-to-Peer systems. A possible way to improve the performance of Peer-to-Peer systems is the overlay network construction based on the knowledge of the physical network topology. In this paper, we will propose the use of the “Record Route” and “Timestamp” options supported in the IP protocol to explore the paths between peers. By the topology-aware peer selection, our approach outperforms traditional P2P systems using random peer selection. Our approach only incurs a low overhead and can be deployed easily in various P2P systems.
Bacterial Foraging Algorithm Based Parameter Estimation of Three Winding Transformer

Transformers are one of the main components of any power system. An accurate estimation of system be-haviour, including load flow studies, protection, and safe control of the system calls for an accurate equiva-lent circuit parameters of all system components such as generators, transformers, etc. This paper presents a methodology to estimate the equivalent circuit parameters of the Three Winding Transformer (TWT) using Bacterial Foraging Algorithm (BFA). The estimation procedure based on load test data at one particular op-erating point namely supply voltage, load currents, input power. The performance characteristics, such as efficiency and voltage regulation are considered along with the name plate data in order to minimize the er-ror between the estimated and measured data. The estimation procedure is demonstrated with a sample three winding transformer and the results are compared against the directly measured performance of TWT and genetic algorithm optimization results. The simulation results show the ability of the proposed technique to capture the true values of the machine parameters and the superiority of the results obtained using the bacte-rial foraging algorithm.
2017 Gatlinburg Conference Symposium Submission

Overview: In neurodevelopmental disorders, such as autism spectrum disorder (ASD), intellectual disability (ID) or Attention Deficit Hyperactivity Disorder (ADHD), the tremendous heterogeneity in etiology and clinical presentation can undermine our ability to effectively stratify patients, target interventions, and predict outcomes from those interventions. Research to improve stratification and outcome measurement in ASD has become increasingly focused on the identification of putative biomarkers, from genetic variants to electrophysiological and imaging characteristics, that may help to define more homogeneous, biologically based subgroups within the spectrum. Electrophysiology (EEG) holds particular promise as a biomarker in neurodevelopmental disorders for both practical and scientific reasons. From a practical standpoint, EEG data acquisition is more feasible than other imaging modalities due to its motion tolerance. Scientifically, EEG measures basic neural processes that are disrupted in neurodevelopmental disorders, such as neural connectivity, circuit formation, and neural synchrony. However, many challenges exist in the development of EEG biomarkers, such as the stability of measures, particularly over developmentally dynamic periods, sensitivity to change, specificity of measures to diagnostic domains and core deficits, and a biomarker’s ability to stratify individuals based on clinical features or likelihood of response to treatment. In this symposium, we will begin with an overview of methodological considerations in EEG studies in neurodevelopmental disorders (Distefano). We then will present data from studies that have taken innovative approaches to identify EEG biomarkers in neurodevelopmental disorders, from ASD (Dickinson) to rare genetic variants (Hudac) to ADHD (Loo). We will discuss common themes across these syndromes that will have relevance to the identification of biomarkers in neurodevelopmental disorders
Taxonomic resolution based on DNA barcoding affects environmental signal in metacommunity structure

Invertebrate communities in freshwater streams form the basis of many biomonitoring protocols that rely on coarse taxonomic resolution. Coarse resolution may group together species with different environmental preferences, masking the relationship between taxonomic composition and environmental variables. Alternatively, closely related species often share similar traits, and therefore, refining taxonomic resolution will not affect, or even may decrease, the strength of relationships between taxa and environment. To test these competing hypotheses, we characterized the metacommunity patterns of 5 orders (Coleoptera, Diptera, Ephemeroptera, Plecoptera, Trichoptera) and 1 subclass (Oligochaeta) of invertebrates in 21 streams in Algonquin Provincial Park, Ontario, Canada. We determined community composition at family, genus, and species (DNA barcode cluster) levels. For each taxonomic level within each order, we computed the amount of variation explained by 20 local environmental and spatial variables. We also compared site diversity rankings, based on richness, Shannon index, and Simpson index values, between species–genus, genus–family, and species–family levels of resolution. We found evidence to support our 2nd hypothesis. Also, reducing taxonomic resolution decreased the consistency of site rankings for all 3 diversity indices. These results suggest the ecological interchangeability of species within genera, or even within families, given the environmental variables we measured. Furthermore, these results emphasize the importance of carefully considering taxonomic resolution for metacommunity work as well as biomonitoring.
Local Decentralization and Economic Growth: Evidence from U.S. Metropolitan and Non-Metropolitan Regions

This paper extends the recent empirical literature on the relationship between local decentralization and growth using data from both metropolitan and non-metropolitan regions in the U.S. The analysis utilizes both metropolitan and non-metropolitan regions, and thus avoids the possible selection bias present in previous research. The results for non-metropolitan regions indicate a relatively weak or negative relationship between the local decentralization measures and local economic growth compared to a positive relationship suggested by a recent study on metropolitan regions. Results for the non-metro regions also suggest that there are different impacts across population and income than we observe for metropolitan regions.

Dynamic contrast-enhanced MRI in cancer

Dynamic contrast-enhanced MRI has been proven to be a valuable technique in cancer imaging. The poorly formed and leaky vessels formed during angiogenesis to supply tumors facilitate an increased uptake of intravenously administered contrast agents in comparison to normal vasculature. The use of mathematical modeling techniques on the change in tumor signal intensity as a function of time provides a valuable insight into the underlying microvasculature of tumors. As an area of active research, the imaging and modeling of dynamic contrast-enhanced MRI data has many challenges. Novel contrast agents and models contribute to a refining of the technique and its application as a diagnostic tool in cancer imaging.
Effect of Autoclaving on Flexibility of Four Different Nickel Titanium Files

EFFECT OF AUTOCLAVING ON FLEXIBILITY OF FOUR DIFFERENT NICKEL TITANIUM FILES Anushree Mehrotra, D.D.S. Marquette University, 2015 Introduction: Nickel-titanium (NiTi) files, introduced over 2 decades ago, have the unique property of superelasticity, are more resistant to fracture and are more flexible than stainless steel files. Recent developments in NiTi include M wire and Controlled/Thermal Memory Technology resulting in files with claimed superior properties to conventional NiTi files. Manufacturers recommend sterilization of files prior to usage. These files may be subjected to further autoclaving if reused. The purpose of this study was to test the effect of multiple cycles of autoclaving on the flexibility of four brands of NiTi files and to evaluate differences between brands. Materials and Methods: HyFlex CM (Coltene Whaldent), Vortex, Profile and Vortex Blue (Dentsply Tulsa Dental Specialties) files of size 35 with 0.04 taper were selected for this study. All files were subjected to 0, 1, 3 and 5 cycles of autoclaving and their flexibility was assessed with cantilever bending at 37C (n=20/brand/cycles). Nonautoclaved files were used as controls. Two-way ANOVA and Post Hoc Tukey’s test were used to assess the differences in flexibility. Results: Autoclaving had no significant (p>0.05) effect on the flexibility within a given file brand but there were significant (p<0.05) differences in flexibility among the brands with the general rankingHyFlex CM > Profile > Vortex > Vortex Blue. Conclusion: Autoclaving had no effect on the mechanical properties of these NiTi rotary files.

Recovery time after localized perturbations in complex dynamical networks

Maintaining the synchronous motion of dynamical systems interacting on complex networks is often critical to their functionality. However, real-world networked dynamical systems operating synchronously are prone to random perturbations driving the system to arbitrary states within the corresponding basin of attraction, thereby leading to epochs of desynchronized dynamics with a priori unknown durations. Thus, it is highly relevant to have an estimate of the duration of such transient phases before the system returns to synchrony, following a random perturbation to the dynamical state of any particular node of the network. We address this issue here by proposing the framework of single-node recovery time (SNRT) which provides an estimate of the relative time scales underlying the transient dynamics of the nodes of a network during its restoration to synchrony. We utilize this in differentiating the particularly slow nodes of the network from the relatively fast nodes, thus identifying the critical nodes which when perturbed lead to significantly enlarged recovery time of the system before resuming synchronized operation. Further, we reveal explicit relationships between the SNRT values of a network, and its global relaxation time when starting all the nodes from random initial conditions. Earlier work on relaxation time generally focused on investigating its dependence on macroscopic topological properties of the respective network. However, we employ the proposed concept for deducing microscopic relationships between topological features of nodes and their respective SNRT values. The framework of SNRT is further extended to a measure of resilience of the different nodes of a networked dynamical system. We demonstrate the potential of SNRT in networks of Rössler oscillators on paradigmatic topologies and a model of the power grid of the United Kingdom with second-order Kuramoto-type nodal dynamics illustrating the conceivable practical applicability of the proposed concept.
Speech rate in Korean across region, gender and generation

Speech in Korean Abstract This paper deals with how speech rate in Korean is affected by the sociolinguistic factors such as region, gender and generation. Speech rate was quantified as articulation rate (excluding physical pauses) and speaking rate (including physical pauses), both expressed as the number of syllables per second (sps). Other acoustic measures such as pause frequency and duration were also examined. Four hundred twelve subjects were chosen from Korean Standard Speech Database considering their age, gender and region. The result shows that generation has a significant effect on both speaking rate and articulation rate. Younger speakers produce their speech with significantly faster speaking rate and articulation rate than older speakers. Mean duration of total pause interval and the total number of pause of older speakers are also significantly different to those of younger speakers. Gender has a significant effect only on articulation rate, which means male speakers’ speech rate is characterized by faster articulation rate, longer and more frequent pauses. Finally, region has no effect both on speaking and articulation rates.

Amaç: Bu çalışmada, sağlıklı bireylerde insan lökosit antijen (HLA) alel frekansları tespit edildi ve HLA alelleri ile ABO kan grupları arasında bir ilişki olup olmadığı irdelendi. Gereç ve yöntemler: İzmir Tepecik Eğitim ve Araştırma Hastanesi Doku Tipleme Laboratuvarı arşivlerinde akrabalık ilişkisi bulunmayan 450 bireyden oluşan HLA-A, HLA-B ve HLA-DRB1 alel frekansları değerlendirildi. Bireylerin HLA genotiplemesi tek spesifik primer-polimeraz zincir reaksiyonu (PCR-SSP) ve diziye özgü oligonükleotid ile PCR (PCR-SSO) yöntemleri kullanılarak analiz edildi. Kan grupları mikroplaka aglütinasyon yöntemi ile değerlendirildi. Bulgular: Her lokustaki en yaygın aleller HLA-A*02, HLA-B*35 ve HLA-DRB1*11 idi. A ve O kan grupları ise sırası ile en yaygın olanlar idi. HLA-B ve HLA-DRB1 lokuslarında HLA ve ABO kan grupları arasında istatistiksel olarak anlamlı bir ilişki saptandı. Sonuç: Çalışmamızın sonuçları, Türkiye nüfusunda yapılan diğer çalışma bulgularını desteklemekle birlikte, HLA çeşitliliği ve antropolojik çalışmalar için ilave katkı sağlayacaktır. İnsan lökosit antijen alel frekanslarının daha iyi anlaşılmasının ulusal nakil stratejilerinin oluşturulmasına yardımcı olacağı kanısındayız. Anahtar sözcükler: Alel; kan grubu; insan lökosit antijenleri. Objectives: This study aims to investigate human leukocyte antigen (HLA) allele frequencies of healthy individuals and to determine whether there is an association between the HLA alleles and ABO blood groups. Materials and methods: The HLA-A, HLA-B and HLA-DRB1 allele frequency were evaluated in a sample of 450 unrelated individuals at Izmir Tepecik Education and Research Hospital Tissue Typing Laboratory archives. The HLA genotypes of individuals were analyzed by using single-specific primerpolymerase chain reaction (PCR-SSP) or PCR using sequence-specific oligonucleotide (PCR-SSO) methods. Blood groups were evaluated by using microplate agglutination method. Results: The most common alleles were HLA-A*02, HLA-B*35, and HLA-DRB1*11 in each locus. A and O blood groups were most common, respectively. A statistically significant association between HLA and ABO blood groups was found in HLA-B and HLA-DRB1 loci. Conclusion: Our study results confirm the other study findings in the Turkish population and also contribute an additional data for further HLA polymorphisms and anthropological studies. We believe that gaining a better understanding on the HLA allele frequencies would help to constitute national transplantation strategies.
