Variability in cytologic-histologic correlation practices and implications for patient safety.

CONTEXT The Clinical Laboratory Improvement Amendments of 1988 require that laboratories perform cytologic-histologic correlation, although the optimal methods and the value of performing correlation have not been determined. OBJECTIVE To determine the similarities and differences in how laboratories perform cytologic-histologic correlation. DESIGN One hundred sixty-two American laboratories were sent a letter requesting copies of the materials they used in the cytologic-histologic correlation process. The returned materials were classified into the categories of forms, logs, and tally sheets. A checklist (derived from the College of American Pathologists Laboratory Accreditation Cytopathology Checklist) was developed to classify the "minimum expected" (15) and "additional" data points that laboratories collected when they performed a correlation. PARTICIPANTS American pathology laboratories. MAIN OUTCOME MEASURES Measures were percentage of laboratories that recorded minimum expected and additional data points and the frequency with which specific minimum expected data points were recorded. RESULTS The response frequency was 32.1%, and a total of 84 cytologic-histologic correlation materials were obtained. The only minimum expected variables recorded on forms or logs by more than 50% of laboratories were cytology case number, sign-out cytology diagnosis, surgical pathology case number, and sign-out surgical pathology diagnosis. Nine (17.3%) laboratories did not record data on forms, logs, or tally sheets. The mean number of minimum expected and additional variables recorded on forms was 6.5 and 8.7, respectively. CONCLUSIONS Laboratories record data from the cytologic-histologic correlation process in a number of ways, indicating the lack of standardization of the data collection process.
A ferromagnetic based variable inductor analysis and design methodology

A ferromagnetic based variable inductor analysis and design methodology is proposed in this paper. This methodology allows predicting the behavior of the designed element simply. The variable inductor fundamentals are detailed as well the proceeding to determine the material relative permeability. The methodology presents a direct relation between the control winding current variation and the main variable inductance distinct relative values. A variable inductor particular structure prototype is built. Finally the results have presented 3.12% error between the experimental prototype and the proposed general equation design methodology.
Impact Of E-Atmospheric Elements On The Perceived Value Of The Online Visit

Websites managers want the consumption experience to be central in the online visit. This study analyzes the effects of experiential components of a website on the online experience. Through experimentation, we handle three elements of the merchant environment (virtual agent, 3D environment and control command). A survey of 272 users shows that the tools manipulated generate perceived value. Furthermore, we test the effect of hedonic and utilitarian value of the visit on the online behavior, highlighting its significant effect. Finally, from a theoretical and a managerial point of view, we elaborate on the necessary conditions for improving the visitor experience and for creating customer values.
Elementary, My Dear Watson—The Era of Natural Language Processing in Transplantation

The use of modern data acquisition and analytics commonly in use in the technology sector by Google, IBM, and others have long been the envy of the health services researcher. In this issue, Srinivas et al. have demonstrated feasibility in the use of data mining and natural language processing (NLP) in data abstraction.1 In their study they developed predictive models for graft loss and patient survival in kidney transplantation using single-center retrospective data.

Financial access 2010 : the state of financial inclusion through the crisis

Financial Access 2010 is the second in a series of annual reports by CGAP (Consultative Group to Assist the Poor) and the World Bank Group to monitor statistics for financial access around the world and to inform the policy debate. The series was launched in response to the increasing interest in financial inclusion among policy makers and the development community. Financial access 2010 aims to contribute to the efforts to measure financial access at the country level worldwide, to develop a consistent database, and to present the data in a coherent manner for future analyses. At the same time, the report recognizes that not all institutions that serve low-income and poor people report to the financial regulators. However, evaluation of specific policy interventions is beyond the scope of this report. The positive relationship between financial development and economic growth is well documented in the literature. In more recent years, the debate has expanded to include the notion of financial 'exclusion' as a barrier to economic development and the need for building inclusive financial systems.
Reactions of Teachers, As Applicants, to Principal Recruitment Practices in a Reform Environment: The Effects of Job Attributes, Job Information Source, and School Level.

The job of principal becomes more challenging as school reform initiatives mandate greater emphasis on instructional leadership and delegate decision making from district central offices to school sites. These changes lend increased importance to the task of principal recruitment, a process involving decisions made by applicants (e.g., decision to apply for the job) as well as organizational representatives. Application decisions must be affirmative or recruitment will fail. Using a 2 x 2 x 3 experimental design, this study examined the effects ofjob attributes (instructional leadership, management), job information sources (school site, district central office) and school level (elementary school, middle school, high school) on reactions of applicants (N = 168) for principal jobs described in recruitment brochures. Reactions were more favorable at the high school level when the job was described with management job attributes. At the elementary and middle school levels, reactions were more favorable when the job was described with instructional leadership job attributes. Implications for practice, certification curricula, and research are discussed.
Imports, Innovation and Employment after Crisis: Evidence from a Developing Country

Imports are often perceived as a threat to employment. However, access to imported intermediate inputs can be essential to stimulate innovation and generate employment. We investigate this question based on a unique dataset of Ecuadorian manufacturing firms, their final products and intermediate inputs. Using fixed effects instrumental variable estimation we find that firms' importing activities lead to product innovation, increase firms' product scope, reduce production costs and create employment. These impacts arise not only for producers in high-tech industries but also for firms in more traditional sectors. Employment effects are much stronger several years after the country's economic crisis.
Joint estimation of the activity and the events of interaction in SPECT systems

We describe a unified probabilistic graphical model for joint reconstruction of the activity and of the coordinates of the events of interaction in Emission Imaging. This new formulation is a discrete-discrete alternative to the discretecontinuous List Mode Likelihood model described by Barrett et at. The discrete-discrete formulation allows us to account for nonhomogeneous resolution of the gamma-camera while adopting computationally efficient shift-invariant projection and backprojection algorithms. We describe an application of the model for the compensation of disrupted photo-detectors is SPECT.
Evaluation of algorithms for microperfusion assessment by fast simulations of laser Doppler power spectral density

In classical laser Doppler (LD) perfusion measurements, zeroth- and first-order moments of the power spectral density of the LD signal are utilized for the calculation of a signal corresponding to the concentration, speed and flow of red blood cells (RBCs). We have analysed the nonlinearities of the moments in relation to RBC speed distributions, parameters of filters utilized in LD instruments and the signal-to-noise ratio. We have developed a new method for fast simulation of the spectrum of the LD signal. The method is based on a superposition of analytically calculated Doppler shift probability distributions derived for the assumed light scattering phase function. We have validated the method by a comparison of the analytically calculated spectra with results of Monte Carlo (MC) simulations. For the semi-infinite, homogeneous medium and the single Doppler scattering regime, the analytical calculation describes LD spectra with the same accuracy as the MC simulation. The method allows for simulating the LD signal in time domain and furthermore analysing the index of perfusion for the assumed wavelength of the light, optical properties of the tissue and concentration of RBCs. Fast simulations of the LD signal in time domain and its frequency spectrum can be utilized in applications where knowledge of the LD photocurrent is required, e.g. in the development of detectors for tissue microperfusion monitoring or in measurements of the LD autocorrelation function for perfusion measurements. The presented fast method for LD spectra calculation can be used as a tool for evaluation of signal processing algorithms used in the LD method and/or for the development of new algorithms of the LD flowmetry and imaging. We analysed LD spectra obtained by analytical calculations using a classical algorithm applied in classical LD perfusion measurements. We observed nonlinearity of the first moment M1 for low and high speeds of particles (v < 2 mm s−1, v > 10 mm s−1). It was also noted that the first moment M1 is less sensitive to the change of the mean RBC speed for flat speed distributions. The low-pass filter frequency f2 implemented in the LD instrument has a significant influence on the first moment of the spectrum. In particular, for a cut-off frequency lower than 10 kHz the M1 value is strongly underestimated.
Analysis of the performance of a multiband passive bistatic radar processing scheme

The bistatic radar has been revitalized over the last few years through the rapid development of the passive bistatic radar technology. Passive bistatic radar systems have unique properties, especially is time on target high compared to traditional radar systems, as well as the freedom in choosing from the available transmitters of opportunity. This paper will focus on how to take advantage of the latter of these two special properties in order to achieve better range resolution while maintaining the high coherent processing interval.
Hand Tracking via Efficient Database Indexing

Tracking the pose of a moving hand from a monocular perspective is a difficult problem. In the current study the tracking problem is recast as efficient database indexing. Recognition is hastened by approximating chamfer distances between hand poses which have been embedded into a common vector space. Using this embedding, a small number of candidate matches for each query can be quickly identified using simple vector comparisons. These candidates are then processed with an expensive metric (chamfer distance) to determine the optimal match. This approach does not suffer from the traditional weakness of tracking methods, and lends itself naturally to real time solutions.
The Online Consumer Trust Construct: A Web Merchant Practitioner Perspective

If companies are to enjoy long-term success in the Internet marketplace, they must effectively manage the complex, multidimensional process of building online consumer trust. eMerchants must understand the characteristics of web interfaces, policies, and procedures that promote trust and enact this knowledge in the form of specific trustbuilding mechanisms. Therefore, eMerchants must exercise a variety of trust-building techniques in the design of their online consumer interface as well as the principles upon which they operate. In doing so, eMerchants look to a variety of sources, outside the discussions available in academic literature, which influence and govern their perception of online consumer trust development. The purpose of this paper is to identify these sources and leverage the theoretical framework of previous academic literature by incorporating these practitioner sources into a framework from which future research efforts of online consumer trust can be based.
Realised hedge ratio properties, performance and implications for risk management: evidence from the spanish ibex 35 spot and futures markets

This paper analysis the properties and performance of daily realised futures hedge ratios. Using five-minute data for the Spanish IBEX-35 equity spot and futures market realised variances, covariances and hedge ratios are constructed. To measure performance we compared a hedged portfolio based upon the realised hedge ratio with hedged portfolios constructed using a constant regression based hedge ratio, a timevarying rolling regression hedge ratio favoured within the finance industry and a timevarying bivariate-GARCH hedge ratio favoured within the academic community. Our results suggest that solely in terms of minimising portfolio variance the static regression, rolling regression and GARCH based methods obtain the smallest portfolio variances; however, this was often at the expense of negative mean values. In contrast, measuring performance that takes into account portfolio mean and variance using the Sharpe ratio, the portfolio based on the realised hedge ratio is almost unanimously favoured.
A Transmission-Line Model for Full-Wave Analysis of Mixed-Mode Propagation

The paper presents a generalized transmission line model able to describe the high-frequency mixed-mode propagation along electrical interconnects. The model is derived from a full-wave formulation and extends the validity of the standard transmission line (TL) model to frequency ranges where the propagation is no longer of transmission electron microscopy (TEM)-type. This generalized TL model describes the high-frequency differential and common mode propagation and the mode conversion. Within its validity limits, the proposed model provides solutions in good agreement with those obtained through full-wave models. Case studies are carried out to evaluate the high-frequency mode conversion in asymmetric interconnects.
Effect of processing conditions on the nutritive value of canola meal and presscake. Comparison of the yellow and brown-seeded canola meal with the brown-seeded canola presscake.

BACKGROUND Canola, unlike traditional rapeseed, contains low levels of 'erucic acid' and 'glucosinolates'. Canola's industrial processing generally involves separation of the seed into an oil and a meal fraction whereas the intermediate product is called presscake. The objective of this study was to determine the effect of processing conditions on the nutritive value for ruminants and compare the yellow (Brassica juncea) (CM_Y) and the brown-seeded (B. napus) (CM_B) canola meal and the brown-seeded (B. napus) (CPC_B) canola presscake. RESULTS Either extract was higher (P<0.05) for CPC_B than for CM_Y and CM_B. CM_Y had a higher (P<0.05) PB2 and PC compared to CM_B. Truly digestible fractions, except fatty acid, were lower (P<0.05) for CPC_B. Effective protein degradability of CM_Y was lower (P<0.05) compared to CM_B or CPC_B. In vitro protein intestinal digestibility for CM_Y was higher (P<0.05) than for CM_B or CPC_B. CONCLUSION CPC_B had lower protein but higher oil content than canola meal and is a potential high-energy supplement source for ruminants. CM_Y had higher crude protein, digestible and metabolizable energy values and low fiber than CM_B. In plant breeding, selection programs are geared towards yellow-seeded varieties in order to improve the nutritive value of canola meal.
Disclosure Rules and Declared Essential Patents

Many standard setting organizations (SSOs) require participants to disclose patents that might be infringed by implementing a proposed standard, and commit to license their “essential” patents on terms that are at least fair, reasonable and non-discriminatory (FRAND). Data from these SSO intellectual property disclosures have been used in academic studies to provide a window into the standard setting process, and in legal proceedings to assess the relative contribution of different parties to a standard. We develop a simple model of the disclosure process to illustrate the link between SSO rules and patent-holder incentives, and examine the model's core predictions using a novel dataset constructed from the disclosure archives of thirteen major SSOs. The central message of the paper is that subtle differences in the rules used by different SSOs can influence which patents are disclosed, the terms of licensing commitments, and ultimately long-run citation and litigation rates for the underlying patents.
Choice Among Alternative Benchmarks: An Asset Pricing Approach

This paper provides an asset pricing rationale for choosing among alternative ways to group securities in applied corporate finance settings. Explicit reference to the asset pricing paradigm has become less prevalent in the empirical corporate finance literature, where there has emerged a preference for grouping securities on the basis of the financial characteristics of the firm and on industry affiliation. We propose a new approach using basis assets that is consistent with the asset pricing paradigm and which explains significantly more of the cross sectional dispersion in asset returns using Generalized Least Squares applied on a security by security basis. A main result of our paper is that this asset-pricing-based approach justifies the use of industrial classifications to construct matched samples and appropriate benchmark performance comparisons.
Feature-preserving image and video compression

Nowadays, mobile devices equipped with cameras are ubiquitous and wireless communication networks are widely accessible. Captured images or videos can be transmitted to a server from anywhere at any time. Owing to limited network resources, e.g., when many consumers compete for the network resources or the wireless link speed is low, images or videos have to be compressed at low bitrates for transmission. Conventional image and video compression standards assume that humans are the information receivers. Therefore, they maximize the quality of the compressed content by exploiting known properties of the human visual perception system. However, lately, in an increasing number of applications, such compressed images or videos are fed into computer vision algorithms for analysis at a server, such as mobile visual search, object retrieval and tracking, and surveillance. This motivates us to control the encoding process in such a way that important features are preserved rather than optimizing it for the human visual system. This thesis presents several works on preserving the most important features when compressing images or videos at relatively low bitrates in a standard-compatible manner. The feature quality is affected significantly by compression artifacts at low bitrates. To design approaches to preserve more features, the properties of typical image features are investigated, and it is found that 1) large-scale features are more robust than small-scale features, 2) keypoint detection is more important than descriptor calculation, and 3) high frequencies of an image are less important for detecting scale-space-based features. Considering these feature properties, various schemes are proposed in this thesis. First, still images are considered and encoded using an image compression standard, e.g., JPEG. Several feature-preservation approaches are proposed based on the aforementioned feature properties: a) deblocking filters are applied to low-quality images, b) a larger number of bits is assigned to small-scale features using a novel rate-distortion model, and c) a novel JPEG quantization table is designed for scale-space-based features. The results show that the proposed approaches lead to higher matching performance when compared with the default JPEG image compression standard. Then, the approaches for images are extended to video compression. Similarly, rate-distortion models are developed to encode videos using the H.264/AVC standard. In addition, in prac-
Challenging Research: Completing Participatory Social Research with Children and Adolescents in a Hospital Setting

OBJECTIVE: A discussion of the challenges to completing participatory social research with children and adolescents in a hospital setting. BACKGROUND: Beginning with the dominant medical culture of hospitals, coupled with a persistent skepticism of social and in particular qualitative research and its contribution to knowledge in medical circles, restrictive contextual challenges also include attitudinal, methodological, and logistical considerations. Together, these challenges hamper good participatory research practice and the capacity to maintain quality data, as well as impede children's participation in research, which has the capacity to contribute to healthcare design, policy, and planning processes. METHODS: Two studies in pediatric settings in Australia, one of which was completed in 2008 and the other which was discontinued in 2011, provide the basis for this research discussion. The discussion addresses the issues that persist in inhibiting the completion of participatory social research and the resulting impacts on research, children's right to participate, and the volume of evidence that is ultimately available from children's perspectives to support and inform healthcare design, planning, and policy in pediatric settings. CONCLUSIONS: Recommendations for changes that could strengthen and improve this research experience include building awareness of the potential value of this research; increasing its influence; building the capacity and knowledge of gatekeepers, ethics committees, and researchers working in this context; and recognizing and valuing children's competence and participation.
Methoxyestradiols Mediate the Antimitogenic Effects of 17&bgr;-Estradiol: Direct Evidence From Catechol-O-Methyltransferase–Knockout Mice

Background—Studies using pharmacological agents suggest but do not prove that the antimitogenic effects of estradiol are caused by conversion of estradiol to hydroxyestradiols (mediated by CYP450s) followed by methylation of hydroxyestradiols to methoxyestradiols (mediated by catechol-O-methyltransferase, COMT). Methods and Results—To test this hypothesis more rigorously, we used aortic smooth muscle cells (SMCs) from mice lacking COMT (COMT-KO). Wild-type (WT) but not COMT-KO SMCs efficiently converted 2-hydroxyestradiol to 2-methoxyestradiol. Both WT and COMT-KO SMCs expressed estrogen receptors. Estradiol and 2-hydroxyestradiol concentration-dependently inhibited serum-induced DNA synthesis, cell numbers, and collagen synthesis in WT but not COMT-KO SMCs. 2-Methoxyestradiol inhibited DNA synthesis, cell numbers, and collagen synthesis in both WT and COMT-KO SMCs. Conclusions—These data provide strong evidence that the vascular antimitogenic effects of estradiol are estrogen receptor–independent and involve the sequential conversion of estradiol to hydroxyestradiols and then to methoxyestradiols.
