Compliance Police or Business Partner? Institutional Complexity and Occupational Tensions in Human Resource Management

Abstract Faced with institutional demands, organizations often create departments whose work is divorced from technical imperatives. This paper examines workers in one such department: Human Resources. Analysis of HR’s recent history and evidence from an ethnographic study of HR work highlight the institutional origins of conflict between HR’s established “compliance police” role and the “business partner” expectations of line managers. The paper outlines a theory of how organizational responses to institutional complexity contribute to persistent tension in HR and other heteronomous occupations.
Singular Spectrum Analysis Window Length Selection in Processing Capacitive Captured Biopotential Signals

Biopotential signals captured by non-contact capacitively coupled biopotential sensing electrodes are easily polluted by different kinds of noises, especially power line noises. Singular spectrum analysis (SSA) algorithm is utilized for processing capacitively captured biopotential signals. By analyzing the spectrum characteristics of the circulant matrix and Toeplitz matrix, it has been found that the window length of SSA is strongly related to the frequency width corresponding to each principal component. A criterion for window length selection is, therefore, proposed and numerically verified by simulated electrocardiography signals. A capacitive-coupled biopotential signal measurement system is constructed to obtain original biopotential signals from human body. Experimental results show that, with the aid of the criterion, satisfied biopotential signals can be effectively obtained by SSA.
Architecture of helix bundle membrane proteins: An analysis of cytochrome c oxidase from bovine mitochondria

We have analyzed the structure of mitochondrial cytochrome c oxidase in terms of general characteristics thought to be important for describing the architecture of helix bundle membrane proteins. Many aspects of the structure are similar to what has previously been found for the photosynthetic reaction center and bacteriorhodopsin. Our results lead to a considerably more precise general picture of membrane protein architecture than has hitherto been possible to obtain.

Don’t Do It Again! Directed Forgetting of Habits

Most daily routines are determined by habits. However, the experienced ease and automaticity of habit formation and execution come at a cost when habits that are no longer appropriate must be overcome. So far, proactive and reactive control strategies that prevent inappropriate habit execution either by preparation or “on the fly” have been identified. Here, we present evidence for a third, retroactive control strategy. In two experiments using the list method of directed forgetting, the accessibility of newly learned and practiced stimulus-response rules was significantly reduced when participants were cued to forget the rules rather than to remember them. The results thus show that directed forgetting, so far observed and investigated only for episodic memory traces, can also be applied to habits. The findings further emphasize the adaptive value of forgetting and can be taken as evidence of a retroactive strategy of habit control.
Genetic Characterization of an H1N2 Influenza Virus Isolated from a Pig In Indiana

ABSTRACT An H1N2 influenza virus was isolated from a pig during an outbreak of respiratory disease and abortion on an Indiana farm in November 1999. Results of phylogenetic analyses indicate that this virus is a reassortant between a recent classical H1 swine virus and the reassortant H3N2 viruses that have emerged among American pigs since 1998.
A pragmatic approach for multidimensional data clustering

Pattern classification and data clustering has emerged as a potential mechanism that classifies data elements based on respective feature homogeneity. Although K-Means clustering has exhibited appreciable performance for data clustering, it suffers from poor optimality when dealing with multi dimensional datasets. In this paper, an evolutionary programming based Bisecting K-Means algorithm called Canonical Genetic Algorithm based Bisecting Clustering (CGABC) has been developed. The proposed model incorporates min-max normalization based feature normalization of the high dimensional data sets, which is followed by T-Test analysis. The fitness value has been assigned based on inter-cluster (heterogeneous distance) and within-cluster (homogeneous distance) distances. The conventional GA has been modified by applying multistage reproduction process, enhanced crossover and mutation. By incorporating the optimized cluster center information, the Bisecting K-Means clustering has been performed, which has exhibited optimal solution for highly accurate and efficient clustering with high dimensional data sets.

Reduction of ferrylmyoglobin and ferrylhemoglobin by nitric oxide: a protective mechanism against ferryl hemoprotein-induced oxidations.

The reactions of metmyoglobin (metMb) and methemoglobin (metHb), oxidized to their respective oxoferryl free radical species (.Mb-FeIV = O/.Hb-4FeIV = O) by tert-butyl hydroperoxide (t-BuOOH), with nitric oxide (NO.) were studied by a combination of optical, electron spin resonance (ESR), ionspray mass (MS), fluorescence, and chemiluminescence spectrometries to gain insight into the mechanism by which NO. protects against oxidative injury produced by . Mb-FeIV = O/. Hb-4FeIV = O. Oxidation of metMb/metHb by t-BuOOH in a nitrogen atmosphere proceeded via the formation of two protein electrophilic centers, which were heme oxoferryl and the apoprotein radical centered at tyrosine (for the .Mb-FeIV = O form, the g value was calculated to be 2.0057), and was accompanied by the formation of t-BuOOH-derived tert-butyl(per)oxyl radicals. We hypothesized that NO. may reduce both oxoferryl and apoprotein free radical electrophilic centers of . Mb-FeIV = O/. Hb-4FeIV = O and eliminate tert-butyl(per)oxyl radicals, thus protecting against oxidative damage. We found that NO. reduced . Mb-FeIV = O/. Hb-4FeIV = O to their respective ferric (met) forms and prevented the following: (i) oxidation of cis-parinaric acid (PnA) in liposomes, (ii) oxidation of luminol, and (iii) formation of the tert-butyl(per)oxyl adduct with the spin trap DMPO. NO. eliminated the signals of tyrosyl radical detected by ESR and oxoferryl detected by MS in the reaction of t-BuOOH with metMb. As evidenced by MS of apomyoglobin, this effect was due to the two-electron reduction of . Mb-FeIV = O by NO. at the oxoferryl center rather than to nitrosylation of the tyrosine residues. Results of our in vitro experiments suggest that NO. exhibits a potent, targetable antioxidant effect against oxidative damage produced by oxoferryl Mb/Hb.
Determination of selected phthalate esters compounds in water and sediments by capillary gas chromatography and flame ionization detector

The presence of phthalate esters (PAEs) in the environment is not desirable and therefore, needs to be monitored. This study reports the first data on the concentration levels of PAEs in water and sediments of the Jukskei River catchment area, South Africa. The study was conducted during the summer and winter seasons of 2005. Liquid-liquid extraction (LLE) and Soxhlet extraction (SE) methods were optimized, evaluated and used to determine PAEs of interest in water (unfiltered and filtered) and sediments samples, respectively. Mean percentage recoveries in spiked doubly distilled water ranged from 100 ± 5.32 dimethyl phthalate (DMP) – 122 ± 0.46 di-2-ethylhexyl phthalate (DEHP) and 91.6 ± 1.93 diethyl phthalate (DEP) – 117 ± 4.80 dibutyl phthalate (DBP) in sediments. The concentration levels of PAEs studied in unfiltered environmental water samples were in the range of 0.04(± 0.00) (DMP) − 9.76(± 00.1) ng mL−1(DEHP) for PAEs and from 0.09 (± 0.01) (DMP) – 4.38 (± 0.06) ng mL−1(DEHP) for filtered environmental water samples. Concentration levels obtained in sediments were from 0.05 (0.00) (DMP) – 4910 (0.36) ng/gdw (DEHP). PAEs adsorbed on the sample bottle gave concentration levels of up to 0.10 (± 0.03) ng mL−1for some samples and no analyte was detected (ND) in some cases Generally, concentrations obtained were below the water quality guideline values of United States Environmental Protection Agency (USEPA).
Use by Banks of Cloud Computing: An Empirical Study

This paper explores the extent to which public cloud computing is in fact being used in practice by banks operating in the EU, including global banks. It is based primarily on anonymised interviews with banks, cloud providers, advisers, and financial services regulators. This paper describes how banks are using cloud computing and their key drivers (such as time to market), as well as real and perceived barriers (such as misconceptions about cloud, and financial services regulation), including cultural and technical/commercial as well as legal/regulatory aspects. It summarises how banks and regulators have approached the cloud, as well as how cloud providers have approached the banking sector.Specific consideration is given to barriers arising from banking regulatory rules on outsourcing, critical or material, and the contentious issue of contractual audit rights for regulators. The paper also analyses legal and practical issues such as risk assessments, security, business continuity including exit plans, concentration risk and bank resolution, continuing regulatory oversight, banking secrecy laws, barriers under data protection law including personal data export restrictions, problems arising from layered service models where SaaS services are built on another provider’s IaaS/PaaS service, and commonly-negotiated contractual provisions regarding termination, service changes and liability.The paper concludes that, while some barriers are internal and some external, cloud is still misunderstood, and further educational efforts are needed to ensure regulatory approaches and guidance are sufficiently cloud-aware to strike the appropriate balance between risk management and efficiency/innovation across the European Economic Area.

Recombinant Tissue-Type Plasminogen Activator Use for Ischemic Stroke in the United States: A Doubling of Treatment Rates Over the Course of 5 Years

Background and Purpose— Recombinant tissue-type plasminogen activator (rtPA) is the only approved therapy for acute ischemic stroke (AIS). In 2004, 1.8% to 2.1% of AIS patients in the United States received rtPA. Given incentives from regulatory agencies and payors to increase rtPA use, we hypothesized that rtPA use in the United States would increase from 2005 to 2009. Methods— AIS cases were defined by exclusion of hemorrhagic stroke and transient ischemic attack International Classification of Diseases 9th revision codes (430, 431, 432, and 435) from diagnosis-related groups 14, 15, 524, and 559 discharges. Patients receiving thrombolytics were identified using International Classification of Diseases 9th revision code 99.10 (Medicare Provider and Analysis Review and Premier databases) and pharmacy billing records (Premier). Change over time and differences between databases were tested using negative binomial regression. Results— Within Medicare Provider and Analysis Review, thrombolytic use increased from 1.1% in 2005 to 3.4% in 2009 (P<0.001 for trend). Within Premier, thrombolytic use increased from 1.4% in 2005 to 3.7% in 2009 for all cases (P<0.001). Analysis of pharmacy billing records in Premier for 50-mg or 100-mg doses of rtPA showed that 3.4% of AIS cases were treated in 2009. Inclusion of patients with transient ischemic attack or hemorrhagic stroke International Classification of Diseases 9th revision codes who received any thrombolytic as “ischemic stroke patients receiving rtPA” changed the rate of thrombolysis to 5.2%. Conclusions— In 2009, 3.4% to 5.2% of AIS patients in the United States received thrombolytics, approximately double the rate of treatment in 2005. Rapid recognition and transport and quick treatment in the emergency department remain goals for further improving treatment rates.
Fair Value Accounting for Commercial Banks: An Empirical Analysis of SFAS No. 107

This study evaluates the association between the market value of banks' common equity and fair value estimates disclosed under Statement of Financial Accounting Standards No. 107, "Disclosures about Fair Value of Financial Instruments. " The results suggest that only the reported fair values of investment securities have incremental explanatory power relative to book value. No reliable evidence of incremental explanatory power is found for the fair value disclosures of loans, deposits, long-term debt or net off-balance sheet financial instruments. After controlling for two competing indicators of value captured by the accrual accounting system, ROE and growth in book value, the fair value of securities no longer exhibits a significant association with market value. Results from estimating a returns specification, which may implicitly control for correlated omitted variables, also exhibit no reliable evidence of significant incremental explanatory power in the fair value estimates.
Credit Card Fraud: Bang in E-Commerce

Recent decades have seen a gigantic expansion in the use of credit cards as a true transactional medium. Data mining is rising as one of the chief features of many homeland security\ initiatives. Often, it is used as a means for detecting fraud, assessing risk, as well as product retailing. Data mining is becoming increasingly common in both the private as well as public sectors. Data mining involves the use of data analysis tools to find out formerly unknown, believable patterns and relationships in large data sets. Credit card offers a number of secondary benefits unavailable from cash or checks. Credit cards are safer from theft than is cash. Fraud detection involves monitoring the behavior of populations of users in order to estimate, detect or avoid unwanted behavior. In this paper, we studied various factors required to distinguish transaction and characterizes factors affecting fraud detection with fraud prevention techniques.
Prevalence of human papillomavirus in mobile tongue cancer with particular reference to young patients

The carcinogenetic role of human papillomavirus (HPV) in mobile tongue cancer remains unclear because of conflicting results reported in the literature. This disparity is likely to be due to variations in the samples and methods used. Furthermore, despite a tendency for increased prevalence of mobile tongue cancer in young adults, only a few reports specifically in young patients have been published. In the present study on 32 patients, including six in their 20s, we genotyped the prevalence of HPV using a highly sensitive detection tool in fresh‐frozen samples from surgical specimens and a novel detection device with electrochemical DNA chip and loop‐mediated isothermal amplification. In addition, we confirmed HPV prevalence by in situ hybridization and immunohistochemistry for the p16INK4a protein, regarded as a biomarker of HPV‐associated cancers. The frequency of 13 genotypes of high‐risk HPV was 0/32 (0%), which was further confirmed by in situ hybridization. Overexpression of p16INK4a protein was observed in six of the 32 patients (19%), with four (67%) also overexpressing p53. Because there is usually a lack of p53 overexpression in HPV‐associated cancer, it is unlikely that p16INK4a protein overexpression is correlated with HPV infection. Consequently, it is unlikely that HPV infection plays an important role in mobile tongue carcinogenesis, in particular in young adults. In addition, our data suggest that the overexpression of p16INK4a protein is not an appropriate biomarker for HPV association in mobile tongue carcinogenesis. (Cancer Sci 2012; 103: 161–168)
Supporting user of information retrieval systems by visualizing the information dialog context

In this paper we present first results for a new approach designing innovative user interfaces for information retrieval systems. The leading thought of this paper is based on the fact that a dialog between user and system during a search process establishes an information dialog context. We introduce a framework for information retrieval systems to handle the activities and sets elaborated within a search process in order to support the user. In this paper we present a prototype tool which provides and visualizes sets of information objects in order to bring users into the position to keep the developed sets within the search process at hand and actively manage them. Finally, a description of a user study and expert interviews and their evaluation results conducted on the basis of the prototypical tool is provided.
Autophagy and Human Disease

As a conserved cellular degradative pathway in eukaryotes, autophagy relieves cells from various types of stress. There are different forms of autophagy, and the ongoing studies of the molecular mechanisms and cellular functions of these processes are unraveling their significant roles in human health. Currently, the best-studied of these pathways is macroautophagy, which is linked to a range of human disease. For example, as part of the host immune defense mechanism, macroautophagy is activated to eliminate invasive pathogenic bacteria; however, in some cases bacteria subvert this process for their own replication. Autophagy also contributes to endogenous major histocompatibility complex class II antigen presentation, reflecting its role in adaptive immunity. In certain neurodegenerative diseases, which are associated with aggregation-prone proteins, macroautophagy plays a protective role in preventing or reducing cytotoxicity by clearance of the toxic proteins; however, the autophagy-dependent processing of some components correlates with the pathogenesis of certain myopathies. Finally, autophagy acts as a mechanism for tumor suppression, although some cancer cells use it as a cytoprotective mechanism. Thus, a fundamental paradox of autophagy is that it can act to promote both cell survival and cell death, depending on the specific conditions.
Arc Dynamic Stabilization in Low-Frequency Square-Wave Electronic Ballast for Metal Halide Lamps

Discharge lamps present a negative dynamic characteristic that makes necessary to use a current limiting element. In high-frequency resonant ballasts, current limitation is performed by the output resonant tank; but in low-frequency square-wave electronic ballasts, arc stabilization is accomplished by the stage feeding the square wave inverter. Therefore, the design of the input converter must be made taking into account the lamp dynamic characteristic. In the present paper, a new procedure to obtain the small-signal dynamic characteristic of metal halide lamps is proposed. Using the proposed methodology, the small-signal characteristic of a 70-W lamp is obtained. This characteristic is then used for the design of an electronic ballast based on a buck-boost converter followed by a full bridge inverter. The limits for stable operation obtained are verified using a laboratory prototype.
The value chain for web accessibility : challenges and opportunities

Abstract.This paper presents the results of interviews with representatives of the three key groups of stakeholders in the value chain for web accessibility: website commissioners, web developers and web accessibility experts. 26 web commissioners, 7 web developers and 14 web accessibility experts were interviewed. The results show that in spite of great efforts by the World Wide Web Consortium, the European Commission and other international and national organizations to promote web accessibility, knowledge of this topic is still low. More critically, the tools to support commissioners, developers and accessibility experts are still very poor and do not provide much of the functionality that the various groups in the value chain need. We believe these results highlight some of the reasons why the state of web accessibility is still as poor as it is.
Infection Rates in HIV-HCV Patients Treated with Interferon Are Similar to Those in HCV Mono-Infection and Not Related to Neutropenia

Abstract Method: Infectious complications were assessed in 25 HIV-HCV coinfected patients receiving 29 courses of HCV therapy (786 person-weeks). Results: The infection rate (1.3 infections/100 person-weeks) was similar when compared to the rate in HIV-negative patients. HIV status and neutrophil nadir did not predict infection risk or rate. Conclusion: Interferon dose reduction and/or G-CSF in HCVtreated HIV patients with neutropenia are not justified.
Frequency Deviation Due to a Sample Insertion Hole in a Cylindrical Cavity by Circuital Analysis

One of the most widely used techniques for dielectric material characterization is the partially filled circular cavity. The exact analysis of this structure is well known in the bibliography. But in practice when the measured material is introduced through a circular pipe below its cut off frequency a problem arises. Traditionally the tube effect is neglected, but then some errors appear, whose magnitude depends on the material properties and the cavity and tube dimensions. In some cases, the errors introduced are noticeable and the tube effect should not be neglected. Some authors have tried to evaluate in a simple way this effect, but their equations are valid only in a restricted range of practical configurations. In this paper we present a model of this effect based on a circuital analysis of the full structure. A simple monomode equation valid for any material property and cavity dimensions is given and a saturation effect, not reported before, is analyzed.
