    Sinusoids are used for making harmonic and other sounds. In order to having life in the sounds and adding a wide variety of noises, irregularities are inserted in the frequency and amplitudes. A simple and intuitive noise model is presented, consisting of a low-pass filtered noise, and having...... control for strength and bandwidth. The noise is added on the frequency and amplitudes of the sinusoids, and the resulting irregularity’s (jitter and shimmer) bandwidth is derived. This, together with an overview of investigation methods of the jitter and shimmer results in an analysis of the necessary...

  2. Electric stimulation with sinusoids and white noise for neural prostheses

    Full Text Available We are investigating the use of novel stimulus waveforms in neural prostheses to determine whether they can provide more precise control over the temporal and spatial pattern of elicited activity as compared to conventional pulsatile stimulation. To study this, we measured the response of retinal ganglion cells to both sinusoidal and white noise waveforms. The use of cell-attached and whole cell patch clamp recordings allowed the responses to be observed without significant obstruction from the stimulus artifact. Electric stimulation with sinusoids elicited robust responses. White noise analysis was used to derive the linear kernel for the ganglion cell’s spiking response as well as for the underlying excitatory currents. These results suggest that in response to electric stimulation, presynaptic retinal neurons exhibit bandpass filtering characteristics with peak response that occur 25ms after onset. The experimental approach demonstrated here may be useful for studying the temporal response properties of other neurons in the CNS.

    Evaluating the exact quantity of noise present in an image and quality of an image in the absence of reference image is a challenging task. We propose a near perfect noise estimation method and a no reference image quality assessment method for images corrupted by Gaussian noise. The proposed methods obtain initial estimate of noise standard deviation present in an image using the median of wavelet transform coefficients and then obtains a near to exact estimate using curve fitting. The proposed noise estimation method provides the estimate of noise within average error of +/-4%. For quality assessment, this noise estimate is mapped to fit the Differential Mean Opinion Score (DMOS) using a nonlinear function. The proposed methods require minimum training and yields the noise estimate and image quality score. Images from Laboratory for image and Video Processing (LIVE) database and Computational Perception and Image Quality (CSIQ) database are used for validation of the proposed quality assessment method. Experimental results show that the performance of proposed quality assessment method is at par with the existing no reference image quality assessment metric for Gaussian noise corrupted images.

    In random vibration environments, sinusoidal line noise may appear in the vibration signal and can affect analysis of the resulting data. We studied two methods which remove stationary sine tones from random noise: a matrix inversion algorithm and a chirp-z transform algorithm. In addition, we developed new methods to determine the frequency of the tonal noise. The results show that both of the removal methods can eliminate sine tones in prefabricated random vibration data when the sine-to-random ratio is at least 0.25. For smaller ratios down to 0.02 only the matrix inversion technique can remove the tones, but the metrics to evaluate its effectiveness also degrade. We also found that using fast Fourier transforms best identified the tonal noise, and determined that band-pass-filtering the signals prior to the process improved sine removal. When applied to actual vibration test data, the methods were not as effective at removing harmonic tones, which we believe to be a result of mixed-phase sinusoidal noise.

  5. An approach to remove impulse noise from a corrupted image

    In this paper, we propose an efficient approach for detecting the impulse noise from corrupted images. This method is based on the principle that the feature of the digital image is usually local correlation and the feature of the impulse noise is usually located near one of the two ends of the image’s maximum and minimum gray values. After the noisy pixel has been detected by the proposed detector, a modified version of the mean filter is proposed to remove the detected impulse noise. Experimental results show that the implementation of the proposed method is simple, and it has better performance than comparison filters with regard to effective noise suppression and preservation of detail, especially when the noise ratio is very high.

    In this paper, we provide a new framework for analyzing corruption in public bureaucracies. The standard way to model corruption is as an example of moral hazard, which then leads to a focus on better monitoring and stricter penalties with the eradication of corruption as the final goal. We propose an alternative approach which emphasizes why corruption arises in the first place. Corruption is modeled as a consequence of the interaction between the underlying task being performed by bureaucra...

    This paper presents two propositions about corruption. First, the structure of government institutions and the political process are a very important determinant of the level of corruption. In particular, weak governments which do not control their agencies would lead to ultra-high corruption levels. Second, the illegality of corruption and the need for secrecy make it much more distortionary and costly than its sister activity, taxation. These results may explain why in some less developed c...

    In this paper operational transresistance amplifier (OTRA) based second and third order sinusoidal oscillators are proposed. The proposed second order oscillator is designed using single OTRA based Sallen Key low pass filter structure and third order oscillator is obtained by cascading three low pass filters and placing in a loop. The non-ideality and phase noise analyses of the circuits are also presented with necessary mathematical formulations. Workability of the proposed oscillators are verified through PSPICE simulations using 0.18µm AGILENT CMOS process parameters. The total harmonic distortion (THD) for proposed second order and third order oscillators are found as 3.27% and 0.631% respectively.

  11. A multi-stage noise adaptive switching filter for extremely corrupted images

    Dinh, Hai; Adhami, Reza; Wang, Yi

    2015-07-01

    A multi-stage noise adaptive switching filter (MSNASF) is proposed for the restoration of images extremely corrupted by impulse and impulse-like noise. The filter consists of two steps: noise detection and noise removal. The proposed extrema-based noise detection scheme utilizes the false contouring effect to get better over detection rate at low noise density. It is adaptive and will detect not only impulse but also impulse-like noise. In the noise removal step, a novel multi-stage filtering scheme is proposed. It replaces corrupted pixel with the nearest uncorrupted median to preserve details. When compared with other methods, MSNASF provides better peak signal to noise ratio (PSNR) and structure similarity index (SSIM). A subjective evaluation carried out online also demonstrates that MSNASF yields higher fidelity.

  12. An all digital phase locked loop for synchronization of a sinusoidal signal embedded in white Gaussian noise

    1973-01-01

    An all digital phase locked loop which tracks the phase of the incoming sinusoidal signal once per carrier cycle is proposed. The different elements and their functions and the phase lock operation are explained in detail. The nonlinear difference equations which govern the operation of the digital loop when the incoming signal is embedded in white Gaussian noise are derived, and a suitable model is specified. The performance of the digital loop is considered for the synchronization of a sinusoidal signal. For this, the noise term is suitably modelled which allows specification of the output probabilities for the two level quantizer in the loop at any given phase error. The loop filter considered increases the probability of proper phase correction. The phase error states in modulo two-pi forms a finite state Markov chain which enables the calculation of steady state probabilities, RMS phase error, transient response and mean time for cycle skipping.

    The false-nearest-neighbors (FNN) algorithm was originally developed to determine the embedding dimension for autonomous time series. For noise-free computer-generated time series, the algorithm does a good job in predicting the embedding dimension. However, the problem of predicting the embedding dimension when the time-series data are corrupted by noise was not fully examined in the original studies of the FNN algorithm. Here it is shown that with large data sets, even small amounts of noise can lead to incorrect prediction of the embedding dimension. Surprisingly, as the length of the time series analyzed by FNN grows larger, the cause of incorrect prediction becomes more pronounced. An analysis of the effect of noise on the FNN algorithm and a solution for dealing with the effects of noise are given here. Some results on the theoretically correct choice of the FNN threshold are also presented.

    To extend the parameter restrictions of a silent echo-planar imaging (sEPI) sequence using sinusoidal readout (RO) gradients, in particular with increased spatial resolution. The sound pressure level (SPL) of the most feasible configurations is compared to conventional EPI having trapezoidal RO gradients. We enhanced the sEPI sequence by integrating a parallel acquisition technique (PAT) on a 3 T magnetic resonance imaging (MRI) system. The SPL was measured for matrix sizes of 64 × 64 and 128 × 128 pixels, without and with PAT (R = 2). The signal-to-noise ratio (SNR) was examined for both sinusoidal and trapezoidal RO gradients. Compared to EPI PAT, the SPL could be reduced by up to 11.1 dB and 5.1 dB for matrix sizes of 64 × 64 and 128 × 128 pixels, respectively. The SNR of sinusoidal RO gradients is lower by a factor of 0.96 on average compared to trapezoidal RO gradients. The sEPI PAT sequence allows for 1) increased resolution, 2) expanded RO frequency range toward lower frequencies, which is in general beneficial for SPL, or 3) shortened TE, TR, and RO train length. At the same time, it generates lower SPL compared to conventional EPI for a wide range of RO frequencies while having the same imaging parameters. Copyright © 2012 Wiley Periodicals, Inc.

    This paper studies the problem of the restoration of images corrupted by mixed Gaussian-impulse noise. In recent years, low-rank matrix reconstruction has become a research hotspot in many scientific and engineering domains such as machine learning, image processing, computer vision and bioinformatics, which mainly involves the problem of matrix completion and robust principal component analysis, namely recovering a low-rank matrix from an incomplete but accurate sampling subset of its entries and from an observed data matrix with an unknown fraction of its entries being arbitrarily corrupted, respectively. Inspired by these ideas, we consider the problem of recovering a low-rank matrix from an incomplete sampling subset of its entries with an unknown fraction of the samplings contaminated by arbitrary errors, which is defined as the problem of matrix completion from corrupted samplings and modeled as a convex optimization problem that minimizes a combination of the nuclear norm and the l(1)-norm in this paper. Meanwhile, we put forward a novel and effective algorithm called augmented Lagrange multipliers to exactly solve the problem. For mixed Gaussian-impulse noise removal, we regard it as the problem of matrix completion from corrupted samplings, and restore the noisy image following an impulse-detecting procedure. Compared with some existing methods for mixed noise removal, the recovery quality performance of our method is dominant if images possess low-rank features such as geometrically regular textures and similar structured contents; especially when the density of impulse noise is relatively high and the variance of Gaussian noise is small, our method can outperform the traditional methods significantly not only in the simultaneous removal of Gaussian noise and impulse noise, and the restoration ability for a low-rank image matrix, but also in the preservation of textures and details in the image.

  18. A combined method to estimate parameters of neuron from a heavily noise-corrupted time series of active potential

    A method that combines the means of unscented Kalman filter (UKF) with the technique of synchronization-based parameter estimation is introduced for estimating unknown parameters of neuron when only a heavily noise-corrupted time series of active potential is given. Compared with other synchronization-based methods, this approach uses the state variables estimated by UKF instead of the measured data to drive the auxiliary system. The synchronization-based approach supplies a systematic and analytical procedure for estimating parameters from time series; however, it is only robust against weak noise of measurement, so the UKF is employed to estimate state variables which are used by the synchronization-based method to estimate all unknown parameters of neuron model. It is found out that the estimation accuracy of this combined method is much higher than only using UKF or synchronization-based method when the data of measurement were heavily noise corrupted.

    1990-01-01

    The ability of feed-forward neural network architectures to learn continuous valued mappings in the presence of noise was demonstrated in relation to parameter identification and real-time adaptive control applications. An error function was introduced to help optimize parameter values such as number of training iterations, observation time, sampling rate, and scaling of the control signal. The learning performance depended essentially on the degree of embodiment of the control law in the training data set and on the degree of uniformity of the probability distribution function of the data that are presented to the net during sequence. When a control law was corrupted by noise, the fluctuations of the training data biased the probability distribution function of the training data sequence. Only if the noise contamination is minimized and the degree of embodiment of the control law is maximized, can a neural net develop a good representation of the mapping and be used as a neurocontroller. A multilayer net was trained with back-error-propagation to control a cart-pole system for linear and nonlinear control laws in the presence of data processing noise and measurement noise. The neurocontroller exhibited noise-filtering properties and was found to operate more smoothly than the teacher in the presence of measurement noise.

  20. Detail-Preserving Restoration of Impulse Noise Corrupted Images by a Switching Median Filter Guided by a Simple Neuro-Fuzzy Network

    2004-01-01

    Full Text Available A new operator for the restoration of digital images corrupted by impulse noise is presented. The proposed operator is a simple recursive switching median filter guided by a neuro-fuzzy network functioning as an impulse detector. The internal parameters of the neuro-fuzzy impulse detector are adaptively optimized by training. The training is easily accomplished by using simple artificial images that can be generated in a computer. The most distinctive feature of the proposed operator over other operators is that it offers excellent detail- and texture-preservation performance, while effectively removing noise from the input image. Extensive experiments show that the proposed operator may be used for efficient restoration of digital images corrupted by impulse noise without distorting the useful information in the image.

    Tikhonov regularization is studied in the case of linear pseudodifferential operator as the forward map and additive white Gaussian noise as the measurement error. The measurement model for an unknown function u(x) is m(x) = Au(x) + δ ε (x), where δ > 0 is the noise magnitude. If ε was an L 2 -function, Tikhonov regularization gives an estimate T α (m) = u∈H r arg min { ||Au-m|| L 2 2 + α||u|| H r 2 } for u where α = α(δ) is the regularization parameter. Here penalization of the Sobolev norm ||u|| H r covers the cases of standard Tikhonov regularization (r = 0) and first derivative penalty (r = 1). Realizations of white Gaussian noise are almost never in L 2 , but do belong to H s with probability one if s < 0 is small enough. A modification of Tikhonov regularization theory is presented, covering the case of white Gaussian measurement noise. Furthermore, the convergence of regularized reconstructions to the correct solution as δ → 0 is proven in appropriate function spaces using microlocal analysis. The convergence of the related finite-dimensional problems to the infinite-dimensional problem is also analysed. (paper)

    A method for correcting the geometric distortion of sinusoidally scanned images was proposed. The generation mechanism of the geometric distortion in sinusoidally scanned images was analyzed. Based on the relationship between the coordinates of uniformly scanned points and those of sinusoidally scanned points, a transformation formula was obtained for correcting the geometric distortion when the sampling rate was a constant. By comparing the forward method with the inverse method, a hybrid method for correcting the geometric distortion of sinusoidally scanned images was proposed. This method takes advantage of both the forward and inverse methods and was proven to be better than either of them in terms of peak signal-to-noise ratio (PSNR). The time consumed by the hybrid method was between the other two. When a higher PSNR is desired, the hybrid method is recommended if time permits. In addition, it is a universal approach to the correction of geometric distortion of the images scanned in the sinusoidal mode

  7. A Kullback-Leibler approach for 3D reconstruction of spectral CT data corrupted by Poisson noise

    2017-09-01

    While standard computed tomography (CT) data do not depend on energy, spectral computed tomography (SPCT) acquire energy-resolved data, which allows material decomposition of the object of interest. Decompo- sitions in the projection domain allow creating projection mass density (PMD) per materials. From decomposed projections, a tomographic reconstruction creates 3D material density volume. The decomposition is made pos- sible by minimizing a cost function. The variational approach is preferred since this is an ill-posed non-linear inverse problem. Moreover, noise plays a critical role when decomposing data. That is why in this paper, a new data fidelity term is used to take into account of the photonic noise. In this work two data fidelity terms were investigated: a weighted least squares (WLS) term, adapted to Gaussian noise, and the Kullback-Leibler distance (KL), adapted to Poisson noise. A regularized Gauss-Newton algorithm minimizes the cost function iteratively. Both methods decompose materials from a numerical phantom of a mouse. Soft tissues and bones are decomposed in the projection domain; then a tomographic reconstruction creates a 3D material density volume for each material. Comparing relative errors, KL is shown to outperform WLS for low photon counts, in 2D and 3D. This new method could be of particular interest when low-dose acquisitions are performed.

    We study the performance of multifractal detrended fluctuation analysis (MF-DFA) applied to long-term correlated and multifractal data records in the presence of additive white noise, short-term memory and periodicities. Such additions and disturbances that can be typically found in the observational records of various complex systems ranging from climate dynamics to physiology, network traffic, and finance. In monofractal records, we find that (i) additive white noise hardly results in spurious multifractality, but causes underestimated generalized Hurst exponents h(q) for all q values; (ii) short-range correlations lead to pronounced crossovers in the generalized fluctuation functions Fq(s) at positions that decrease with increasing moment q, thus causing significantly overestimated h(q) for small q and spurious multifractality; (iii) periodicities like seasonal trends (with standard deviations comparable with the one of the studied process) result in spurious “reversed” multifractality where h(q) increases with increasing q (except for very short time windows). We also show that in multifractal cascades moderate additions of noise, short-range memory, or periodic trends cause flawed results for h(q) with q2 remains nearly unchanged.

  15. Sinusoidal Representation of Acoustic Signals

    Honda, Masaaki

    Sinusoidal representation of acoustic signals has been an important tool in speech and music processing like signal analysis, synthesis and time scale or pitch modifications. It can be applicable to arbitrary signals, which is an important advantage over other signal representations like physical modeling of acoustic signals. In sinusoidal representation, acoustic signals are composed as sums of sinusoid (sine wave) with different amplitudes, frequencies and phases, which is based on the timedependent short-time Fourier transform (STFT). This article describes the principles of acoustic signal analysis/synthesis based on a sinusoid representation with focus on sine waves with rapidly varying frequency.

    We consider a neoclassical growth model with endogenous corruption. Corruption and wealth, which are co-determined in equilibrium, are shown to be negatively correlated. Richer countries tend to be less corrupt, and corrupt economies tend to be poorer. This observation gives rise to the following puzzle: If poorer countries do indeed experience higher levels of corruption, and if indeed as suggested by a number of empirical studies corruption hampers growth, then how did rich countries, who w...

  18. Sinusoidal Order Estimation Using Angles between Subspaces

    Directory of Open Access Journals (Sweden)

    Søren Holdt Jensen

    2009-01-01

    Full Text Available We consider the problem of determining the order of a parametric model from a noisy signal based on the geometry of the space. More specifically, we do this using the nontrivial angles between the candidate signal subspace model and the noise subspace. The proposed principle is closely related to the subspace orthogonality property known from the MUSIC algorithm, and we study its properties and compare it to other related measures. For the problem of estimating the number of complex sinusoids in white noise, a computationally efficient implementation exists, and this problem is therefore considered in detail. In computer simulations, we compare the proposed method to various well-known methods for order estimation. These show that the proposed method outperforms the other previously published subspace methods and that it is more robust to the noise being colored than the previously published methods.

    Corruption is often portrayed as a barrier to trade and investment capable of altering international investment patterns. Here, we analyze how firms’ choice of country and the volume of offshored material inputs are affected by corruption in target economies. Taking stance from the gravity model of trade, the analysis suggests that corruption is a deterrent for offshoring. Firms avoid corrupt countries and, given that destination country has been chosen it reduces the volume of offshored inpu...

  1. Adaptive filtering techniques for gravitational wave interferometric data: Removing long-term sinusoidal disturbances and oscillatory transients

    Science.gov (United States)

    Chassande-Mottin, E.; Dhurandhar, S. V.

    2001-02-01

    It is known by the experience gained from the gravitational wave detector prototypes that the interferometric output signal will be corrupted by a significant amount of non-Gaussian noise, a large part of it being essentially composed of long-term sinusoids with a slowly varying envelope (such as violin resonances in the suspensions, or main power harmonics) and short-term ringdown noise (which may emanate from servo control systems, electronics in a nonlinear state, etc.). Since non-Gaussian noise components make the detection and estimation of the gravitational wave signature more difficult, a denoising algorithm based on adaptive filtering techniques (LMS methods) is proposed to separate and extract them from the stationary and Gaussian background noise. The strength of the method is that it does not require any precise model on the observed data: the signals are distinguished on the basis of their autocorrelation time. We believe that the robustness and simplicity of this method make it useful for data preparation and for the understanding of the first interferometric data. We present the detailed structure of the algorithm and its application to both simulated data and real data from the LIGO 40 m prototype.

    In this paper, we analyze implications of corruption on growth. We extend existing growth models by incorporating ubiquitous corruption as a by-product of the public sector. Corruption affects both taxation and public good provision, and therefore causes income redistribution and inefficiencies in the public sector. These effects of corruption lead to lower growth through distortions of investment incentives and resources allocation.

For the analysis we use rule of law, regulatory quality, control over corruption and secondary school enrollment ratio as control variables. We find that democracy, rule of law and control over corruption decreases the level of corruption. When we allowed for interaction effect among independent variables we find the evidence of strong interaction effect between all of the explanatory variables. We also find that, surprisingly, higher democracy and rule of law are positively associated with the level of corruption while higher bureaucracy negatively.

    A combined method composing of the unscented Kalman filter (UKF) and the synchronization-based method is proposed for estimating electrophysiological variables and parameters of a thalamocortical (TC) neuron model, which is commonly used for studying Parkinson's disease for its relay role of connecting the basal ganglia and the cortex. In this work, we take into account the condition when only the time series of action potential with heavy noise are available. Numerical results demonstrate that not only this method can estimate model parameters from the extracted time series of action potential successfully but also the effect of its estimation is much better than the only use of the UKF or synchronization-based method, with a higher accuracy and a better robustness against noise, especially under the severe noise conditions. Considering the rather important role of TC neuron in the normal and pathological brain functions, the exploration of the method to estimate the critical parameters could have important implications for the study of its nonlinear dynamics and further treatment of Parkinson's disease.

  4. Tax structure and corruption

    Directory of Open Access Journals (Sweden)

    Ilić-Popov Gordana

    2014-01-01

    Full Text Available In the article an analysis of the impact of corruption, both administrative and state capture, on the tax structure is carried out. The authors established a negative correlation between the degree of corruption and the height of the effective tax burden, while isolating a simultaneous directly proportional impact of the nominal tax burden (which could reflect state intervention - the main corruption factor on the scope of corruption. The effects of corruption on the decrease of individual taxes' share in GDP are diversified, with impact on direct taxes as a whole being more observable. The mode of tax assessment significantly determines exposure of certain tax to the administrative corruption: it is generally larger in case of taxes assessed by the decision of the competent tax officials who are carrying out both assessment and audit, while in the case of self-assessment and withholding they just perform audits implying limited exposure to corruption. Corruptive state capture is present in the case of taxes which are important for influential corruptors. That is why in Serbia laws preventing taxation of capital gains or heavier taxation of dividends and other income paid to non-residents located in the tax havens were adopted, while by-laws which should have enabled implementation of prescribed lump sum taxation based on external signs of wealth have not been enacted. The authors concluded that the anti-corruption strategy should rely on the increasing role of self-assessment, which could reduce the room for administrative corruption. Unclear and imprecise formulations of the tax norms facilitate corruption, because they create room for arbitrariness in interpretation and implementation of the laws and by-laws. It is therefore necessary to surprises discretion, simplify tax procedure and diminish the number of tax relief's.

    Many regard corruption to be detrimental to international trade. Some, however, think that corruption greases commerce in case of low-quality institutions. Others argue that arbitrary corruption is more damaging to trade than predictable corruption. This is the first paper to test these hypotheses empirically with trade-related measures of corruption. It finds that in general, corruption is detrimental to international trade. However, bribe paying may be beneficial in countries with very long...

  6. Cosmology and the Sinusoidal Potential

    Science.gov (United States)

    Bartlett, David F.

    2006-06-01

    The nature of dark matter (and dark energy) remains a mystery. An alternative is being explored by several scientists: changing Newton's (and Einstein's) field equations. The sinusoidal potential is the latest attempt[1]. Here the gravitational law is alternately attractive and repulsive:φ = -GM cos(kor)/r, where λo=2π/ko = 1/20 of the distance from the sun to the center of the Milky Way. The proposal accommodates several structural features of the Milky Way including, paradoxically, its spiral shape and flat rotation curve. The sinusoidal potential's unique feature is strong galactic tidal forces (dg/dr). These may explain why the new planetoid Sedna is securely between the Kuiper Belt and the Oort cloud and why distant comets are more influenced by galactic tides that are in the r, rather than the z-direction.At this meeting I discuss the consequences of the sinusoidal potential for cosmology. Here the alternation of attraction and repulsion gives (i) an open universe, and (ii) gravitational lensing which is usually weak, but occasionally very strong. An open universe is one that, asymptotically, has a size R which varies directly as time t. The open universe conflicts both with the old Einstein-deSitter model (R α t2/3} and the new accelerating one. The evidence for an accelerating universe decisively rejects the Einstein-deSitter model. The rejection of an open (or empty) universe is less secure. This rejection is influenced by the different ways the groups studying the brightness of supernovae use the HST. Surprising additional inputs include neutrino masses, the equivalence principle, LSB galaxies, and "over-luminous" Sn1a. I thank Mostafa Jon Dadras and Patrick Motl for early help and John Cumalat for continual support. [1] D.F. Bartlett, "Analogies between electricity and gravity", Metrologia 41, S115-S124 (2004).

  8. CORRUPTION IN FRANCE

    2016-07-01

    Full Text Available In accordance with the research conducted by Transparency International, in the period from 2009 until 2012, it is found that this European country did not undergo drastic changes during this period, when it comes to its ranking. According to this research, France belongs to the countries that undertake appropriate measures for the fight against corruption – and it is at a satisfactory level in modern conditions, even in well-developed countries. Corruption in France rests on three major authorities: the Financial Intelligence Unit, the Central Service for the Prevention of Corruption (SCPC and the Central Brigade for the Fight against Corruption (BCLC. As a result of the good institutional cooperation, France is prepared to prevent corruption in the state authorities. The international community disposes of data that refer to the detrimental and difficult consequences caused by corruption. Such findings led to two key issues – prevention of corruption and fight against corruption, not only in France, but in other countries as well. In order to overcome this large-scale problem, many international documents have been adopted, ratified by the Republic of Macedonia.

    Like intergroup violence (Chap. 7) and insurgency (Chap. 8), crime and ­corruption are nearly inevitable companions of an international intervention. Both contribute to the reasons why the intervention occurs, and both may even grow and fester as side-effects of an intervention. Moreover, crime and corruption frequently serve as obstacles to a successful termination of an intervention.

  12. Full-Band Quasi-Harmonic Analysis and Synthesis of Musical Instrument Sounds with Adaptive Sinusoids

    Directory of Open Access Journals (Sweden)

    Marcelo Caetano

    2016-05-01

    Full Text Available Sinusoids are widely used to represent the oscillatory modes of musical instrument sounds in both analysis and synthesis. However, musical instrument sounds feature transients and instrumental noise that are poorly modeled with quasi-stationary sinusoids, requiring spectral decomposition and further dedicated modeling. In this work, we propose a full-band representation that fits sinusoids across the entire spectrum. We use the extended adaptive Quasi-Harmonic Model (eaQHM to iteratively estimate amplitude- and frequency-modulated (AM–FM sinusoids able to capture challenging features such as sharp attacks, transients, and instrumental noise. We use the signal-to-reconstruction-error ratio (SRER as the objective measure for the analysis and synthesis of 89 musical instrument sounds from different instrumental families. We compare against quasi-stationary sinusoids and exponentially damped sinusoids. First, we show that the SRER increases with adaptation in eaQHM. Then, we show that full-band modeling with eaQHM captures partials at the higher frequency end of the spectrum that are neglected by spectral decomposition. Finally, we demonstrate that a frame size equal to three periods of the fundamental frequency results in the highest SRER with AM–FM sinusoids from eaQHM. A listening test confirmed that the musical instrument sounds resynthesized from full-band analysis with eaQHM are virtually perceptually indistinguishable from the original recordings.

    Full Text Available Corruption as a phenomenon is of great interest for the society we live in. As there is no unit of measurement to determine the scale of this phenomenon, comparative studies are chosen most often for the areas concerned. The present paper describes a study focused on all counties in Romania, Bucharest included. The purpose of this research is to establish the determinant factors that influence the size and spread of corruption, as it manifests strong negative effects on the society we live in. Thus, using a set of regressions over the main variables, some correlation coefficients have been set, which after processing rendered a ranking of all the 42 analysed territorial units, sorted by the estimated size of corruption. The whole scientific approach was completed with a map of corruption, which synthesizes and presents the corruption spread nationwide

  15. Designing and Implementation of Stable Sinusoidal Rough-Neural Identifier.

    Science.gov (United States)

    Ahmadi, Ghasem; Teshnehlab, Mohammad

    2017-08-01

    A rough neuron is defined as a pair of conventional neurons that are called the upper and lower bound neurons. In this paper, the sinusoidal rough-neural networks (SR-NNs) are used to identify the discrete dynamic nonlinear systems (DDNSs) with or without noise in series-parallel configuration. In the identification of periodic nonlinear systems, sinusoidal activation functions provide more efficient neural networks than the sigmoidal activation functions. Based on the Lyapunov stability theory, an online learning algorithm is developed to train the SR-NNs. The asymptotically convergence of the identification error to zero and the boundedness of parameters as well as predictions are proved. SR-NNs are used to identify some DDNSs and the cement rotary kiln (CRK). CRK is a complex nonlinear system in the cement factory, which produces the cement clinker. The experiments show that the SR-NNs in the identification of nonlinear systems have better performances than multilayer perceptrons (MLPs), sinusoidal neural networks, and rough MLPs, particularly in the presence of noise.

Corruption affects both taxation and public good provision, and therefore causes income redistribution and inefficiencies in the public sector. These effects of corruption lead to lower growth through distortions of investment incentives and resources allocation.

    The corruption dynamics is analyzed by means of the lattice model which is similar to the three-dimensional Ising model. Agents placed at nodes of the corrupt network periodically choose to perfom or not to perform the act of corruption at gain or loss while making decisions based on the process history. The gain value and its dynamics are defined by means of the Markov stochastic process modelling with parameters established in accordance with the influence of external and individual factors on the agent's gain. The model is formulated algorithmically and is studied by means of the computer simulation. Numerical results are obtained which demonstrate asymptotic behaviour of the corruption network under various conditions.

    Last year there was a heated debate regarding clinical trials with AZT carried out in developing countries. AIDS vaccine trials also posed various dilemmas and ethical problems. In this paper I will consider the possibility of corruption in bioethics, and international multi-centre research will be taken as an example. International clinical trials will be seen from another perspective. I will try to show that the possibility of systemic corruption should be considered when designing an international multi-centre research trial which may involve countries in very different situations regarding corruption. I will analyze three different approaches to this problem and suggest some strategies regarding their capacity to exclude the possibility of corruption.

    Full Text Available There is no sustainable economic development without a functioning rule of law. Besides sustainable economic policies like low interest rates, low inflation, low budget deficit, reasonable taxes and economic freedom for business development, the necessary ones for country’s economic growth are functioning of state institutions, support and development of reforms as well as successful fight against corruption. Corruption is a phenomena often encountered and spread in countries that have problems with rule of law as well as with judiciary system. Corruption manifestation is inevitable in circumstances when state institutions are weak. The phenomena is especially problematic in countries that go through transition periods since these countries are often characterized as nonefficient in fighting this phenomena1 . Countries in transition continue to have the image of countries with high level of corruption, which causes serious crisis from local opinion and continuous demand from international community due to the unsuccessful fight against this malevolence. World Bank considers corruption as the biggest obstacle in the fight for poverty eradication, since it undermines the rule of law, weakens state institutions and most of all it affects the poor. Politically, it undermines democracy and good governance, economic equal growth and development, as well as people’s trust in state institutions. Lately, several anti-corruption laws have been adopted in Kosovo, but they have not been implemented in practice and were not sufficient in fight against corruption.

    Cooperation is ubiquitous in the natural world. What seems nonsensical is why natural selection favors a behavior whereby individuals would lose out by benefiting their competitor. This conundrum, for almost half a century, has puzzled scientists and remains a fundamental problem in biology, psychology, and economics. In recent years, the explanation that punishment can maintain cooperation has received much attention. Individuals who punish noncooperators thrive when punishment does not entail a cost to the punisher. However when punishment is costly, cooperation cannot be preserved. Most literature on punishment fails to consider that punishers may act corruptly by not cooperating when punishing noncooperators. No research has considered that there might be power asymmetries between punishers and nonpunishers that turn one of these type of individuals more or less susceptible to experiencing punishment. Here, we formulate a general game allowing corruption and power asymmetries between punishers and nonpunishers. We show that cooperation can persist if punishers possess power and use it to act corruptly. This result provides a new interpretation of recent data on corrupt policing in social insects and the psychology of power and hypocrisy in humans. These results suggest that corruption may play an important role in maintaining cooperation in insects and human societies. In contrast with previous research, we contend that costly punishment can be beneficial for social groups. This work allows us to identify ways in which corruption can be used to the advantage of a society. © 2010 The Author(s). Evolution© 2010 The Society for the Study of Evolution.

    Full Text Available This article is about increase corruption in private sector as commercial corruption. This establishes a wide understanding of that phenomenon in social science and law. Corruption and bribery are types of fraud and are linked with the private sector too. Although certain types of corruption will decline as the private sector grows and consolidates, other new types involving private sector firms may increase. The commercial corruption can be described as relation inside of an organization and as relation between firms. Corruption in private sector in Poland is connected with social distrust and specific organizational culture, too. Commercial corruption is a familiar feature of their societies and has been the focus of law enforcement and institutional reform. Many others problems do not change the fact that such corruption is a new important problem and causes lost of competitiveness and creates a substitute for fair market and competition in Polish economy and abroad.

The evidence presented shows that higher corruption is associated with (i) higher public investment; (ii) lower government revenues; (iii) lower expenditures on operations and maintenance; and (iv) lower quality of public infrastructure. The evidence also shows that corruption inc...

    Corruption is a global problem that takes special place in health care system. A large number of participants in the health care system and numerous interactions among them provide an opportunity for various forms of corruption, be it bribery, theft, bureaucratic corruption or incorrect information. Even though it is difficult to measure the amount of corruption in medicine, there are tools that allow forming of the frames for possible interventions.

  10. A continuous wavelet transform approach for harmonic parameters estimation in the presence of impulsive noise

    Science.gov (United States)

    Dai, Yu; Xue, Yuan; Zhang, Jianxun

    2016-01-01

    Impulsive noise caused by some random events has the main character of short rise-time and wide frequency spectrum range, so it has the potential to degrade the performance and reliability of the harmonic estimation. This paper focuses on the harmonic estimation procedure based on continuous wavelet transform (CWT) when the analyzed signal is corrupted by the impulsive noise. The digital CWT of both the time-varying sinusoidal signal and the impulsive noise are analyzed, and there are two cross ridges in the time-frequency plane of CWT, which are generated by the signal and the noise separately. In consideration of the amplitude of the noise and the number of the spike event, two inequalities are derived to provide limitations on the wavelet parameters. Based on the amplitude distribution of the noise, the optimal wavelet parameters determined by solving these inequalities are used to suppress the contamination of the noise, as well as increase the amplitude of the ridge corresponding to the signal, so the parameters of each harmonic component can be estimated accurately. The proposed procedure is applied to a numerical simulation and a bone vibration signal test giving satisfactory results of stationary and time-varying harmonic parameter estimation.

  11. Initiation of corrupt exchanges and severity of corruption

    Directory of Open Access Journals (Sweden)

    Rajeev K. Goel

    2013-06-01

    Full Text Available This paper examines the effectiveness of corruption control depending upon whether the bribe taker or the bribe giver initiates the corrupt interaction. The probability of corrupt exchanges depends upon the bribe and the corrupt market structure. The probability of apprehension is set but punishment can be influenced via bribes. Results show that the effectiveness of apprehension hinges on whether higher bribes invite harsher fines. Competition for favors intimidates the bribe giver into offering lower bribes, while greater agency competition has a similar effect on the bribe demanded. Consistent with intuition, better paid bureaucrats demand smaller bribes. Some implications for anti-corruption policy are discussed.

    2013-01-01

    Does perceived corruption in recipient countries reduce support for foreign aid in donor countries? This under-explored yet salient question is examined using the 2009 Eurobarometer survey for the 27 EU countries. We suggest that perceived corruption can cause aid fatigue but that this relationship...... is highly contextualized. The results show that perceptions about corruption in developing countries reduce overall support for aid among respondents in donor countries. However, this effect is mitigated by country and contextual-level effects and different understandings of what we call the “aid-corruption...... paradox,” namely that the need for foreign aid is often the greatest in corrupt environments. Three different dynamics of the aid-corruption paradox influence support for aid: moral, pragmatic, and strategic understandings. In EU-15 countries, the effect of perceived corruption in recipient states on aid...

    Full Text Available Nowadays, in Serbia, it's fashionable to talk about the fight against corruption. 'The spook of fighting corruption circulates through Serbia'. Is there a chance the fight will win the way it's lead? We are convinced there isn't. Since corruption is a process caused by 'rotten' characters, the anti-corruption fight must also be a process of rehabilitation and creation of the right character - the good householder's character. In this process each aspect is important (legal, economic… but for permanent eradication of the evil or the sin of corruption the most important segment is educational because it creates the genuine moral and spiritual value in a hardworking and long-term manner. In 'the period rich in disasters' (Tacitus, in the hard circumstances lasting too long, which would not be endured by any other nation, many values​​, material and moral have inevitably failed. A Serb has endured but also has worn out and lost many virtues, particularly the spirit of a good householder. Mutual hatred seems to be stronger than love, distrust greater than confidence, doubt stronger than faith, and robbery and spoils stronger than charity and solidarity. We need to restore the balance and despite the hardships, and because of them, we must foster mutual love, harmony, unwavering patriotism and value of domesticity. In other words, we must ensure victory of virtue over vice that threatens us from everywhere, both from inside and outside. At the time of 'nuclear techniques and jungle ethics' (Justin Popović the dispersed home of the Serbs can be turned again into a proper home only if we 'have the spirit of domesticity reigning' (Nikolaj Velimirović.

  15. Adaptive noise cancellation

    International Nuclear Information System (INIS)

    Akram, N.

    1999-01-01

    In this report we describe the concept of adaptive noise canceling, an alternative method of estimating signals corrupted by additive noise of interference. The method uses 'primary' input containing the corrupted signal and a 'reference' input containing noise correlated in some unknown way with the primary noise, the reference input is adaptively filtered and subtracted from the primary input to obtain the signal estimate. Adaptive filtering before subtraction allows the treatment of inputs that are deterministic or stochastic, stationary or time variable. When the reference input is free of signal and certain other conditions are met then noise in the primary input can be essentially eliminated without signal distortion. It is further shown that the adaptive filter also acts as notch filter. Simulated results illustrate the usefulness of the adaptive noise canceling technique. (author)

    Corruption is bad for donor business. Corruption reduces popular support for aid in donor countries. However, aid agencies should pay attention to corruption because it is the right thing to do, rather than just the smart thing to do.

    2016-07-01

    Full Text Available Perception studies of corruption have proliferated in the last decade. However, there is a lingering controversy over the proper us of the outputs from such studies to benefit anti-corruption efforts. Against this backdrop, these paper reviews the theoretical context of the perception studies of corruption and their justifications. It examined key perception studies of corruption at the global, regional and national levels in relation to Nigeria and discusses key issues associated with them. These include controversies around the definition of corruption, methodological issues such as the reliability of the perception approach to the study of corruption, possibilities of cross country comparisons, the connections between global, regional and local anticorruption studies and the issue of how such studies and rankings reflect power relations. The paper argues that perception studies will be significant and effective to the extent that elites and government officials continue to take the opinion and perception of citizens and other stakeholders seriously.

    Corruption can arise in any bureaucracy that has the authority to allocate benefits and impose costs.

International development institutions propose long lists of anticorruption initiatives for state bureaucracies, hoping that at least some will be effective. But effective solutions in one context may be entirely ineffective in another.

  4. Interests and corruption

    Directory of Open Access Journals (Sweden)

    Joković Milica S.

    2017-01-01

    Full Text Available This paper analyses the connection of interests and corruption, especially corruption and political interests. It first considers the notion of interest, i.e. its meanings and significance, both for an individual and for a society. It presents the classification if interests by Albion Woodbury Small. A special emphasis is given to the encounter of different interests as the beginning of clash between humans. The paper analyses individual, special and general interests, as well as their relations. The paper also analyses two levels of conflict of interest: the conflict between public and private interest and the conflict between interests within the public offices. The relation of interests in society and politics is solved in the best way by adopting laws, i.e. by introducing the rule of law into political order. Without that the interest orientation of politicians can easily end up in abuse and illegality. In turn, abuses and illegalities open the possibilities for various kinds of corruptive acts.

    2014-01-01

    Full Text Available In this contribution an encryption method using a chaotic oscillator, excited by “n” sinusoidal signals, is presented. The chaotic oscillator is excited by a sum of “n” sinusoidal signals and a message. The objective is to encrypt such a message using the chaotic behavior and transmit it, and, as the chaotic system is perturbed by the sinusoidal signal, the transmission security could be increased due to the effect of such a perturbation. The procedure is based on the regulation theory and consider that the receiver knows the frequencies of the perturbing signal, with this considerations the algorithm estimates the excitation in such a way that the receiver can cancel out the perturbation and all the undesirable dynamics in order to produce only the message. In this way we consider that the security level is increased.

    2015-12-01

    Cavitation characteristics of hydrofoils with sinusoidal leading edge were examined experimentally at a Reynolds number of 7.2 × 105. The hydrofoils had an underlying NACA 634-021 profile and an aspect ratio of 4.3. The sinusoidal leading edge geometries included three amplitudes of 2.5%, 5%, and 12% and two wavelengths of 25% and 50% of the mean chord length. Results revealed that cavitation on the leading edge-modified hydrofoils existed in pockets behind the troughs whereas the baseline hydrofoil produced cavitation along its entire span. Moreover, cavitation on the modified hydrofoils appeared at consistently lower angles of attack than on the baseline hydrofoil.

    In many poor countries, over 80% of the population have experienced corrupt practices in the health sector. In rich countries, corruption takes other forms such as overbilling. The causal link between low levels of the quality of government (QoG) and population health can be either direct or indirect. Using cross-sectional data from more than 120 countries, our findings are that more of a QoG variable is positively associated with higher levels of life expectancy, lower levels of mortality rates for children and mothers, higher levels of healthy life expectancies and higher levels of subjective health feelings. In contrast to the strong relationships between the QoG variables and the health indicators, the relationship between the health-spending measures and population health are rather weak most of the time and occasionally non-existent. Moreover, for private health spending as well as for private share of total health spending, the relation to good health is close to zero or slightly negative. The policy recommendation coming out of our study to improve health levels around the world, in rich countries as well as in poor countries, is to improve the QoG and to finance health care with public, not private, money.

    A recently published article on corruption in Indian healthcare in the BMJ has triggered a hot debate and numerous responses (1, 2, 3, 4). We do agree that corruption in Indian healthcare is a colossal issue and needs to be tackled urgently (5). However, we want to highlight that corruption in healthcare is not a local phenomenon confined to the Indian subcontinent, though India does serve as a good case study and intervention area due to the magnitude of the problem and the country's large population (6). Good governance, strict rules, transparency and zero tolerance are some of the strategies prescribed everywhere to tackle corruption. However, those entrusted with implementing good governance and strict rules in India need to go through a process of introspection to carry out their duties in a responsible fashion. At present, it looks like a no-win situation. In this article, we recommend education in medical ethics as the major intervention for dealing with corruption in healthcare.

  2. Discourses of Anti-corruption in Mexico. Culture of Corruption or Corruption of Culture?

    Directory of Open Access Journals (Sweden)

    Gabriela Coronado

    2008-02-01

    Full Text Available In the context of global capitalism the so-called developing countries are considered ‘commodities’ in offer in the global economy as emerging markets or for foreign investment. Countries need to show they are potentially highly competitive with low risk. The value of country characteristics is set by globalised managerial discourses, based on postcolonial ideologies that rate cultures and societies in terms of linear notions of progress and civilisation. Cultures and behaviours are judged positively or negatively according to the position countries supposedly have in the evolution of world society. In this framework one element that countries need to eradicate or reduce in order to be seen as ‘attractive’ is corruption. Towards this aim international and national government and non-government organisations have put in place anti-corruption campaigns. In communications with the general public, these schemes represent actors and acts of corruption through discursive strategies that characterize world cultures and their links with corruption in terms of postcolonial ideologies. In this paper I focus on the implications of the metaphor ‘culture of corruption’ for rating countries, questioning its effectiveness in anti-corruption campaigns. I argue that anti-corruption instruments based on postcolonial ideologies corrupt representations of national cultures and peoples behaviours, instead of targeting local and global sectors that gain from institutionalised corruption. Through the analysis of anti-corruption cultural texts publicly available in Mexico I illustrate how the ideological misrepresentation of corruption fails its stated aim, to transform a ‘culture of corruption’ into a ‘culture of legality’.

    Many countries do not have the facilities necessary to process their nuclear waste. They have to export it to another country with suitable facilities. Some countries in Europe both export their own waste and import other peoples. This situation is described with details of facilities available and current practices of who sends what where. The problem of nuclear waste processing and disposal has led to corruption and widespread malpractice, in particular in West Germany and Belgium. Although not involved with these scandals Britain will receive large amounts of spent nuclear fuel once the THORP (Thermal Oxide Reprocessing Plant) is ready at BNFL's site at Sellafield. Britain will then have to deal with companies and countries whose record on the transportation of nuclear waste is bad. (U.K.)

Then, the paper shifts gears to the institutional context, arguing that the best account of institutional corruption in the extant literature is of the pollution kind. It then fills the remaining logical space by laying out a conception of institutional corruption as disloyalty and explaining its moral significance for the political legitimacy of a democracy.

    Full Text Available Nowadays companies worldwide are battling to survive and grow in what have continued to be highly adverse economic conditions. In this regard, many multinationals have intensified their efforts to detect and investigate the cases of corruption, as a special form of fraud. The purpose of this article is to analyze the cases of corruption identified within companies in the last year, the evolution of this negative phenomenon and the general perception of companies in this matter. Taking into consideration the aspects above we focus on the conceptual framework of corruption and the studies conducted in the past, later describing its main characteristics and form of manifestations. Finally, we present recent findings of corruption studies issued at the beginning of 2014.

  11. Notes on Corruption and Morality

    An actor perspective within a moralistic approach to corruption in india and Southeast Asia contrasts to a (Weberian) institutional one. This emphasizes local values which help explain apparent lack of social constraints to everyday corrupt practices as bribery. In Karnataka the approach indicates that status and power within one’s own community gained by amassing wealth however acquired overrides morality; overstepping moral taboos can easily be rectified through an appropriate ritual.

    2016-01-01

    Endemic corruption in the country, the rising numbers in higher education, heightened competition between educational institutions at various levels and the creation of improper dependencies among all actors involved in the higher education sector are most likely the main reasons for the extensive spread of corruption at Russian universities. This paper discusses these issues as well as their consequences for further domestic development and for international cooperation with Russia.

  13. Communication system with adaptive noise suppression

    2007-01-01

    A signal-to-noise ratio dependent adaptive spectral subtraction process eliminates noise from noise-corrupted speech signals. The process first pre-emphasizes the frequency components of the input sound signal which contain the consonant information in human speech. Next, a signal-to-noise ratio is determined and a spectral subtraction proportion adjusted appropriately. After spectral subtraction, low amplitude signals can be squelched. A single microphone is used to obtain both the noise-corrupted speech and the average noise estimate. This is done by determining if the frame of data being sampled is a voiced or unvoiced frame. During unvoiced frames an estimate of the noise is obtained. A running average of the noise is used to approximate the expected value of the noise. Spectral subtraction may be performed on a composite noise-corrupted signal, or upon individual sub-bands of the noise-corrupted signal. Pre-averaging of the input signal's magnitude spectrum over multiple time frames may be performed to reduce musical noise.

    Sinusoidal obstruction syndrome (SOS), a form of drug-induced liver injury related to oxaliplatin treatment, is associated with postoperative morbidity after hepatectomy. This study aimed to examine the impact of regorafenib, the first small-molecule kinase inhibitor to show efficacy against metastatic colorectal cancer, on a rat model of SOS. Rats with monocrotaline (MCT)-induced SOS were divided into two groups according to treatment with either regorafenib (6 mg/kg) or vehicle alone, which were administered at 12 and 36 h, respectively, before MCT administration. Histopathologic examination and serum biochemistry tests were performed 48 h after MCT administration. Sinusoidal endothelial cells were evaluated by immunohistochemistry and electron microscopy. To examine whether regorafenib preserved remnant liver function, a 30% hepatectomy was performed in each group. The rats in the vehicle group displayed typical SOS features, whereas these features were suppressed in the regorafenib group. The total SOS scores were significantly lower in the regorafenib group than in the vehicle group. Immunohistochemistry and electron microscopy showed that regorafenib had a protective effect on sinusoidal endothelial cells. The postoperative survival rate after 7 d was significantly better in the regorafenib group than that in the vehicle group (26.7% versus 6.7%, P Regorafenib reduced the phosphorylation of extracellular signal-regulated kinase, which induced matrix metalloproteinase-9 (MMP-9) activation and decreased the activity of MMP-9, one of the crucial mediators of SOS development. Regorafenib suppressed MCT-induced SOS, concomitant with attenuating extracellular signal-regulated kinase phosphorylation, and MMP-9 activation, suggesting that regorafenib may be a favorable agent for use in combination with oxaliplatin-based chemotherapy.

  15. Approximations to camera sensor noise

    Jin, Xiaodan; Hirakawa, Keigo

    2013-02-01

    Noise is present in all image sensor data. Poisson distribution is said to model the stochastic nature of the photon arrival process, while it is common to approximate readout/thermal noise by additive white Gaussian noise (AWGN). Other sources of signal-dependent noise such as Fano and quantization also contribute to the overall noise profile. Question remains, however, about how best to model the combined sensor noise. Though additive Gaussian noise with signal-dependent noise variance (SD-AWGN) and Poisson corruption are two widely used models to approximate the actual sensor noise distribution, the justification given to these types of models are based on limited evidence. The goal of this paper is to provide a more comprehensive characterization of random noise. We concluded by presenting concrete evidence that Poisson model is a better approximation to real camera model than SD-AWGN. We suggest further modification to Poisson that may improve the noise model.

  16. Political corruption and weak state

    Directory of Open Access Journals (Sweden)

    Stojiljković Zoran

    2013-01-01

    Full Text Available The author starts from the hypothesis that it is essential for the countries of the region to critically assess the synergy established between systemic, political corruption and a selectively weak, “devious” nature of the state. Moreover, the key dilemma is whether the expanded practice of political rent seeking supports the conclusion that the root of all corruption is in the very existence of the state - particularly in excessive, selective and deforming state interventions and benefits that create a fertile ground for corruption? The author argues that the destructive combination of weak government and rampant political corruption is based on scattered state intervention, while also rule the parties cartel in the executive branch subordinate to parliament, the judiciary and the police. Corrupt exchange takes place with the absence of strong institutional framework and the precise rules of the political and electoral games, control of public finances and effective political and anti-monopoly legislation and practice included. Exit from the current situation can be seen in the realization of effective anti­corruption strategy that integrates preventive and repressive measures and activities and lead to the establishment of principles of good governance.

  18. Combating Corruption Based on International Rules

    2014-08-01

    Full Text Available Corruption is a universal problem that is taking place all over the world, either in developed countries or developing or under developing countries. It is caused by some issues such as poorly designed economic policies, low levels of education, underdeveloped civil society, and the weak accountability of public institution. Those causes of corruption can be separated in some different types of corruption. The types are bureaucratic corruption, political corruption, grand corruption, and common corruption. In terms of tackling some problems of corruption, there are so many things to do including international law commitment. Some international law commitment can be seen like OAS Convention, OECD’s anti-bribery Convention, the UN Convention against Transnational Organized Crime, and the United Nation Convention against Corruption (UNCAC. Those laws must be analyzed not only in context of substantive of those laws but also how they are implemented in state practices.

  19. Perception of the dynamic visual vertical during sinusoidal linear motion.

    Science.gov (United States)

    2017-10-01

    The vestibular system provides information for spatial orientation. However, this information is ambiguous: because the otoliths sense the gravitoinertial force, they cannot distinguish gravitational and inertial components. As a consequence, prolonged linear acceleration of the head can be interpreted as tilt, referred to as the somatogravic effect. Previous modeling work suggests that the brain disambiguates the otolith signal according to the rules of Bayesian inference, combining noisy canal cues with the a priori assumption that prolonged linear accelerations are unlikely. Within this modeling framework the noise of the vestibular signals affects the dynamic characteristics of the tilt percept during linear whole-body motion. To test this prediction, we devised a novel paradigm to psychometrically characterize the dynamic visual vertical-as a proxy for the tilt percept-during passive sinusoidal linear motion along the interaural axis (0.33 Hz motion frequency, 1.75 m/s 2 peak acceleration, 80 cm displacement). While subjects ( n =10) kept fixation on a central body-fixed light, a line was briefly flashed (5 ms) at different phases of the motion, the orientation of which had to be judged relative to gravity. Consistent with the model's prediction, subjects showed a phase-dependent modulation of the dynamic visual vertical, with a subject-specific phase shift with respect to the imposed acceleration signal. The magnitude of this modulation was smaller than predicted, suggesting a contribution of nonvestibular signals to the dynamic visual vertical. Despite their dampening effect, our findings may point to a link between the noise components in the vestibular system and the characteristics of dynamic visual vertical. NEW & NOTEWORTHY A fundamental question in neuroscience is how the brain processes vestibular signals to infer the orientation of the body and objects in space. We show that, under sinusoidal linear motion, systematic error patterns appear in the

  20. Corruption, regionalization and local governance

    Directory of Open Access Journals (Sweden)

    Vuković Slobodan V.

    2002-01-01

    Full Text Available Corruption is old almost as human societies and it was developed simultaneously with enlargement of social and political power, bureaucracy and involvement of the state into market transactions. Specific conditions that are characteristic of Serbian society and that have favorably influenced the growth of corruption are: dissolution/break up of Yugoslavia war in surroundings, economic sanctions and NATO bombing. Besides these basic causes of corruption in Serbia are state control over the economy, lack of the rule of law, and breakdown of social values, that is, anomy and poverty. The lack of the rule of law and the state control of economy, which often occur together, are older conditions, while distorted social values, that is, moral crisis and poverty are newer. Subordination of judicial system to the executive authorities enabled different sorts of bribe and corruption to be tolerated. Therefore, the corruption has spread and became contemporary method of conducting business and almost a common thing, regardless of the party composition of the authorities. This thesis is confirmed by the empirical data: 17.9% of citizens claim that all local officials and corrupted and 48.4% claim that majority of them are. On the other side, only 27.5% of citizens claim that local party officials (all of them or majority accept bribe, and 31.1% claim that only some do. Therefore, we are faced with higher interest in political engagement, because it is becoming a highly profitable occupation and posts in local government are highly appreciated because corruption profit is calculated in advance.

  1. New Approaches for Channel Prediction Based on Sinusoidal Modeling

    Directory of Open Access Journals (Sweden)

    Ekman Torbjörn

    2007-01-01

    Full Text Available Long-range channel prediction is considered to be one of the most important enabling technologies to future wireless communication systems. The prediction of Rayleigh fading channels is studied in the frame of sinusoidal modeling in this paper. A stochastic sinusoidal model to represent a Rayleigh fading channel is proposed. Three different predictors based on the statistical sinusoidal model are proposed. These methods outperform the standard linear predictor (LP in Monte Carlo simulations, but underperform with real measurement data, probably due to nonstationary model parameters. To mitigate these modeling errors, a joint moving average and sinusoidal (JMAS prediction model and the associated joint least-squares (LS predictor are proposed. It combines the sinusoidal model with an LP to handle unmodeled dynamics in the signal. The joint LS predictor outperforms all the other sinusoidal LMMSE predictors in suburban environments, but still performs slightly worse than the standard LP in urban environments.

  6. Credibility Test for Frequency Estimation of Sinusoid Using Chebyshev’s Inequality

    Directory of Open Access Journals (Sweden)

    Hu Guobing

    2014-01-01

    Full Text Available Estimation of sinusoid frequency is a key research problem related to radar, sonar, and communication systems. The results of numerous investigations on frequency estimation have been reported in the literature. Nevertheless, to the best of our knowledge, none of them have dealt with credibility evaluation, which is used to decide whether an individual frequency estimate of the sinusoid is accurate or not. In this study, the credibility problem is modeled as a hypothesis test based on Chebyshev’s inequality (CI. The correlation calculated from the received signal and the reference signal generated according to the frequency estimate is used as a test statistic. A threshold is determined based on CI, and the analytical expression for the frequency estimation credibility detection performance is derived. Simulations show that the proposed method performs well even at low signal-to-noise ratios.

  7. Current-phase relations and noise in rf biased SQUIDS

    International Nuclear Information System (INIS)

    Jackel, L.D.; Clark, T.D.; Buhrman, R.A.

    1975-01-01

    An investigation was made of the effect of the weak link current-phase relation on noise in rf biased SQUIDs. Non-sinusoidal current-phase relations were observed in various weak links, and these non-sinusoidal relations were correlated with significantly increased intrinsic noise in the SQUID ring. The current-phase relation was also found to affect the amplitude of the rf SQUID ring dissipation. The result of an rf SQUID system noise analysis shows that, due to increased intrinsic noise and reduced ring dissipation, the minimum attainable noise for a SQUID ring having a very non-sinusoidal current-phase relation is considerably greater than for a ring with a sinusoidal relation

    The goal of this paper is to expose the research misconduct of pharmaceutical industry sponsored clinical trials via three short case studies of corrupted psychiatric trials that were conducted in the United States. We discuss the common elements that enable the misrepresentation of clinical trial results including ghostwriting for medical journals, the role of key opinion leaders as co-conspirators with the pharmaceutical industry and the complicity of top medical journals in failing to uphold standards of science and peer review. We conclude that the corruption of industry-sponsored clinical trials is one of the major obstacles facing evidence-based medicine.

    Full Text Available AbstractCorruption in the public sector is seen by citizens and public authorities as a major problem for the of system integrity across Europe.The aim of the work was to perform a comparative analysis in terms of corruption in EU globally in 2014, with emphasis on institutionalized corruption. Variables were used on the dynamics of corruption, such as the index of perception of corruption and the corruption level  in public institutions. In this regard, we used surveys initiated by Transparency International, Global Integrity and the European Commission and DNA. It is not to be neglected the answer to the question Why have you not reported an incident of corruption? 58% of Romanians said it would not make any difference, and 20% of respondents said they fear the consequences.Comprehensive anti-corruption policy is expressed in the most efficient manner, through a national program to prevent corruption, articulated in sector prevention strategies directed towards the most vulnerable targets: politics, administration and justice.Keywords: public institutions, transparency, corruption, perception index of corruption, the corruption level in institutions.

  9. The 3-D alignment of objects in dynamic PET scans using filtered sinusoidal trajectories of sinogram

    International Nuclear Information System (INIS)

    Kostopoulos, Aristotelis E.; Happonen, Antti P.; Ruotsalainen, Ulla

    2006-01-01

    In this study, our goal is to employ a novel 3-D alignment method for dynamic positron emission tomography (PET) scans. Because the acquired data (i.e. sinograms) often contain noise considerably, filtering of the data prior to the alignment presumably improves the final results. In this study, we utilized a novel 3-D stackgram domain approach. In the stackgram domain, the signals along the sinusoidal trajectory signals of the sinogram can be processed separately. In this work, we performed angular stackgram domain filtering by employing well known 1-D filters: the Gaussian low-pass filter and the median filter. In addition, we employed two wavelet de-noising techniques. After filtering we performed alignment of objects in the stackgram domain. The local alignment technique we used is based on similarity comparisons between locus vectors (i.e. the signals along the sinusoidal trajectories of the sinogram) in a 3-D neighborhood of sequences of the stackgrams. Aligned stackgrams can be transformed back to sinograms (Method 1), or alternatively directly to filtered back-projected images (Method 2). In order to evaluate the alignment process, simulated data with different kinds of additive noises were used. The results indicated that the filtering prior to the alignment can be important concerning the accuracy

    Full Text Available This paper investigates the effect of provincial corruption on the performance of local development bank, specifically to the profitability and credit quality. We use the data of 26 local development banks in 2012 and 2013. For the provincial corruption measurement we use “Public Institution Openness Index”. Results of this study are first, corruption significantly has a negative effect on the profitability of local development bank. Second, corruption doesn’t affect the credit quality of local development bank. These results are expected to enrich the within country corruption effect to the economic studies, particularly to the local development bank which is infrequently investigated.

    2016-03-01

    Full Text Available Education is universally valued as a formative condition of human and national development. Corruption not only distorts access to education but also affects the quality of education and the reliability of academic research findings. Corruption risks can be found at every level of education and research systems. Corruption in education has adverse implications for educational quality and learning outcomes. Financial fraud remains a major challenge for universities. The lack of academic integrity can also lead to corruption practices. The ingredients of good university governance can be used for combating corruption. Better management, good governance and oversight of funds in traditionally vulnerable areas, could help reduce financial fraud in education system.

  12. Quadratic sinusoidal analysis of voltage clamped neurons.

    Science.gov (United States)

    Magnani, Christophe; Moore, Lee E

    2011-11-01

    Nonlinear biophysical properties of individual neurons are known to play a major role in the nervous system, especially those active at subthreshold membrane potentials that integrate synaptic inputs during action potential initiation. Previous electrophysiological studies have made use of a piecewise linear characterization of voltage clamped neurons, which consists of a sequence of linear admittances computed at different voltage levels. In this paper, a fundamentally new theory is developed in two stages. First, analytical equations are derived for a multi-sinusoidal voltage clamp of a Hodgkin-Huxley type model to reveal the quadratic response at the ionic channel level. Second, the resulting behavior is generalized to a novel Hermitian neural operator, which uses an algebraic formulation capturing the entire quadratic behavior of a voltage clamped neuron. In addition, this operator can also be used for a nonlinear identification analysis directly applicable to experimental measurements. In this case, a Hermitian matrix of interactions is built with paired frequency probing measurements performed at specific harmonic and interactive output frequencies. More importantly, eigenanalysis of the neural operator provides a concise signature of the voltage dependent conductances determined by their particular distribution on the dendritic and somatic membrane regions of neurons. Finally, the theory is concretely illustrated by an analysis of an experimentally measured vestibular neuron, providing a remarkably compact description of the quadratic responses involved in the nonlinear processing underlying the control of eye position during head rotation, namely the neural integrator.

  13. A Statistical and Spectral Model for Representing Noisy Sounds with Short-Time Sinusoids

    Myriam Desainte-Catherine

    2005-07-01

    Full Text Available We propose an original model for noise analysis, transformation, and synthesis: the CNSS model. Noisy sounds are represented with short-time sinusoids whose frequencies and phases are random variables. This spectral and statistical model represents information about the spectral density of frequencies. This perceptually relevant property is modeled by three mathematical parameters that define the distribution of the frequencies. This model also represents the spectral envelope. The mathematical parameters are defined and the analysis algorithms to extract these parameters from sounds are introduced. Then algorithms for generating sounds from the parameters of the model are presented. Applications of this model include tools for composers, psychoacoustic experiments, and pedagogy.

    2007-03-01

    We report quantitative relations between corruption level and economic factors, such as country wealth and foreign investment per capita, which are characterized by a power law spanning multiple scales of wealth and investment per capita. These relations hold for diverse countries, and also remain stable over different time periods. We also observe a negative correlation between level of corruption and long-term economic growth. We find similar results for two independent indices of corruption, suggesting that the relation between corruption and wealth does not depend on the specific measure of corruption. The functional relations we report have implications when assessing the relative level of corruption for two countries with comparable wealth, and for quantifying the impact of corruption on economic growth and foreign investment.

    2017-11-01

    Full Text Available In development policy circles, corruption has become a pressing global issue. Yet the contemporary relationship between corruption and development is complex and contested. For many, corruption robs people of economic resources and social wealth, and denudes the state of important capacities. That is, corruption prevents or blocks development. For others, corruption often occurs in the process of development as the form in which a class of developers accumulates wealth. That is, corruption is a phase of development. This article explores the contested relationship through two case studies: in Sub-Saharan Africa; and in the former Soviet Union. The article also links contemporary debates about corruption and development with earlier thinking about capitalist progress and development.

    Edgar A Duéñez-Guzmán

    Full Text Available Punishment offers a powerful mechanism for the maintenance of cooperation in human and animal societies, but the maintenance of costly punishment itself remains problematic. Game theory has shown that corruption, where punishers can defect without being punished themselves, may sustain cooperation. However, in many human societies and some insect ones, high levels of cooperation coexist with low levels of corruption, and such societies show greater wellbeing than societies with high corruption. Here we show that small payments from cooperators to punishers can destabilize corrupt societies and lead to the spread of punishment without corruption (righteousness. Righteousness can prevail even in the face of persistent power inequalities. The resultant righteous societies are highly stable and have higher wellbeing than corrupt ones. This result may help to explain the persistence of costly punishing behavior, and indicates that corruption is a sub-optimal tool for maintaining cooperation in human societies.

    Full Text Available This paper is focused on the issue of corruption perception in the Czech Republic. After introducing the general framework for corruption perception in post-communist countries, this paper uses the Czech Republic as an example of the ways in which corruption is perceived, the areas Czech citizens feel are most plagued by corruption, and the ways in which corruption perception has transformed in terms of post-communist developments. This paper points out the differences in corruption perception among Czech citizens, the media and political parties and their representatives. The conclusion of the paper attempts to answer the question of how corruption perception has affected the overall perception of the democratic regime in the Czech Republic. It also asks questions regarding how this has influenced the evaluation of democracy and the relationship between Czech citizens and political institutions, including individual political parties.

    This study was conducted in Serbian companies on licensed engineers and in its first part included a total of 336 licensed engineers who voluntarily completed the questionnaires about their ethical orientation and attitudes toward corruption and in the second part 214 engineers who participated in the first survey, who voluntarily evaluated their company's business operations characteristics. This study has clearly shown that there is a direct significant influence of the engineer's ethical orientations and attitudes toward corruption on their evaluation of the characteristics of their respective companies regarding business operations. This research also clearly shows that only engineers with a strong deontological orientation, low ethical subjectivity, and strong readiness to fight corruption, low corruption acceptance and high awareness of corruption can successfully fight corruption, improve the business operations of their companies and make beneficial changes to society. Otherwise, they should be considered as corruption perpetrators, not just as its victims.

    Major forms of corruption constitute a strong threat to the functioning of societies. The most frequent explanation of how severe corruption emerges is the slippery-slope metaphor-the notion that corruption occurs gradually. While having widespread theoretical and intuitive appeal, this notion has barely been tested empirically. We used a recently developed paradigm to test whether severely corrupt acts happen gradually or abruptly. The results of four experimental studies revealed a higher likelihood of severe corruption when participants were directly given the opportunity to engage in it (abrupt) compared with when they had previously engaged in minor forms of corruption (gradual). Neither the size of the payoffs, which we kept constant, nor evaluations of the actions could account for these differences. Contrary to widely shared beliefs, sometimes the route to corruption leads over a steep cliff rather than a slippery slope.

  2. Stacked Denoising Tensor Auto-Encoder for Action Recognition With Spatiotemporal Corruptions.

    Spatially or temporally corrupted action videos are impractical for recognition via vision or learning models. It usually happens when streaming data are captured from unintended moving cameras, which bring occlusion or camera vibration and accordingly result in arbitrary loss of spatiotemporal information. In reality, it is intractable to deal with both spatial and temporal corruptions at the same time. In this paper, we propose a coupled stacked denoising tensor auto-encoder (CSDTAE) model, which approaches this corruption problem in a divide-and-conquer fashion by jointing both the spatial and temporal schemes together. In particular, each scheme is a SDTAE designed to handle either spatial or temporal corruption, respectively. SDTAE is composed of several blocks, each of which is a denoising tensor auto-encoder (DTAE). Therefore, CSDTAE is designed based on several DTAE building blocks to solve the spatiotemporal corruption problem simultaneously. In one DTAE, the video features are represented as a high-order tensor to preserve the spatiotemporal structure of data, where the temporal and spatial information are processed separately in different hidden layers via tensor unfolding. In summary, DTAE explores the spatial and temporal structure of the tensor representation, and SDTAE handles different corrupted ratios progressively to extract more discriminative features. CSDTAE couples the temporal and spatial corruptions of the same data through a thorough step-by-step procedure based on canonical correlation analysis, which integrates the two sub-problems into one problem. The key point is solving the spatiotemporal corruption in one model by considering them as noises in either spatial or temporal direction. Extensive experiments on three action data sets demonstrate the effectiveness of our model, especially when large volumes of corruption in the video.

    Full Text Available The article is aimed at determining the efficiency of repressive anti-corruption measures in conditions of high-level corruption. It is shown that the formal rules regulating the use of repressive methods of countering corruption are characterized by a significant level of the target inefficiency of formal rules. Resulting from ignorance as to the causes of both occurence and spread of corruption – the inefficiency of the current formal rules – repressive anti-corruption measures are fundamentally incapable of achieving a significant reduction in the level of corruptness. It has been proved that, in addition to significant target inefficiency, repressive anti-corruption methods can potentially lead to increased levels of corruption because of abusing by supervisory officials of their official duties and the spread of internal corruption within anti-corruption structures. The potential threats from the uncontrolled anti-corruption structures towards other controlling organizations were considered. It is shown that in conditions of high-level corruption repressive anti-corruption measures can lead to expansion of imitation of anti-corruption activity.

  14. Humane Orientation and Corruption in Bank Lending

    Directory of Open Access Journals (Sweden)

    Siwapong Dheera-aumpon

    2017-12-01

    Full Text Available Corruption in bank lending can seriously adversely affect credit allocation. Besides banking factors, national culture can also affect the corruption of bank officials. Prior studies have shown that collectivism increases bank corruption. This paper aims to assess the effects of cultural dimensions, besides collectivism, on the corruption of bank officials. Instead of using Hofstede's cultural data, this paper uses the data from the GLOBE project which is more recent and reports more cultural dimensions than Hofstede’s. Using the data covering more than 3000 firms in 32 countries, this paper finds that humane orientation increases the corruption of bank officials. The effect of humane orientation on the corruption of bank officials is not only statistically significant but also economically relevant. The magnitude of its effect is relatively comparable to that of collectivism.

  15. Public Debt, Corruption and Sustainable Economic Growth

    Directory of Open Access Journals (Sweden)

    2017-03-01

    Full Text Available There are many studies that look into the relationship between public debt and economic growth. It is hard to find, however, research addressing the role of corruption between these two variables. Noticing this vacancy in current literature, we strive to investigate the effect of corruption on the relationship between public debt and economic growth. For this purpose, the pooled ordinary least squares (OLS, fixed effects models and the dynamic panel generalized method of moments (GMM models (Arellano-Bond, 1991 are estimated with data of 77 countries from 1990 to 2014. The empirical results show that the interaction term between public debt and corruption is statistically significant. This confirms the hypothesis that the effect of public debt on economic growth is a function of corruption. The sign of the marginal effect is negative in corrupt countries, but public debt enhances economic growth within countries that are not corrupt, i.e., highly transparent.

  16. Economic effects of corruption in judiciary

    Directory of Open Access Journals (Sweden)

    Begović Boris

    2005-01-01

    Full Text Available The aim of the paper was to explore economic effects of corruption in judiciary. The examination included the analysis of economic features of judiciary and economic mechanisms of corruption in judiciary within the theoretical framework of Backer's model of criminal behavior. The analysis demonstrates that corruption in judiciary violates the rule of law, hence undermines the fundaments of market economy and specialization, i.e. social division of labor as the ground for improving economic efficiency. As to the static economic efficiency, the most important effect of corruption in judiciary is transaction costs that are generated and the consequent allocative inefficiency. As to the dynamic economic efficiency, corruption decreases economic growth rates and reallocates recourses from productive to distributive activities. The effects of corruption in judiciary to economic inequality are not significant, particularly not comparing with the already identified effects to the economic efficiency.

  8. The Manifestation of Corruption in Eastern Europe

    Directory of Open Access Journals (Sweden)

    Viacheslav Hladky

    2018-01-01

    Full Text Available The purpose of this article is to identify the main manifestations of corruption in the states of Eastern Europe, and, first of all, in Ukraine, which since 2014 has been actively carrying out multiple anti-corruption transformations, although the state is becoming increasingly corrupt every year. The author defines the main groups of manifestations of corruption and analyzes their constituent elements, in the light of which, delineates such categories as "gratitude", bribe, and corruption "gratitude". Particular attention is paid to the study of corruption intercession, which unites nepotism, cronyism and corruption lobbying. It is noted that to date nepotism is essentially supplanted by the rabble, which is the advantage of "privatization" of the state in the light of the clan capitalism. It is concluded that bribery and deviant intercession (corruption protection, as the main manifestations of corruption, the facts that corruption behavior is life-affirming security and protective actions of people, to which they resort, on the one hand, because of the insolvency of the state and society, but, on the other hand, to optimize the achievement of the good that is provided by the state and society, however, in an improper way. Meanwhile, if the discrepancy measures and methods of granting the benefits of state benefits (i.e., on average, the measure and method is applicable, then ignoring the state provision of certain goods as such (i.e., they can be provided only in the corruption plane - this phenomenon is completely objective. On this basis, it is argued that the policy of counteracting corrupt practices in the state should focus, first of all, on the solution of such problems and objective problems, the refusal to account, which will lead to further criminalization of the society, which is observed, in particular, in modern Ukraine.

    2012-05-01

    Using two ethnographic case studies, the intersecting dynamics of inequality, morality, and corruption are examined as they play out in Nigerian AIDS NGOs. To the Nigerian public, local AIDS organizations are widely seen as conduits for corruption. But local opinions of particular NGOs and their leaders turn less on whether donor resources were misused and more on the ways that people who accumulate the benefits of corruption use them socially. Nevertheless, discontent swirls about corruption in general, a fact that suggests a gradual change in people's understandings of the processes that produce inequality in Nigeria.

In this sense Serbia is not exception, on the contrary, it was always highly ranked in all corruption indices of Transparency International. Among social areas which are considered as saturated with corruption highly ranked is the field of university education. In order to check justification of such perceptions, we have conducted a survey among Belgrade University employees. The findings confirmed that there exist corruption in high education on one side and that there is not too much readiness of employees to oppose it, if not to tear it out, than at least to diminish it.

    Weisel, Ori; Shalvi, Shaul

    2015-01-01

    Cooperation is essential for completing tasks that individuals cannot accomplish alone. Whereas the benefits of cooperation are clear, little is known about its possible negative aspects. Introducing a novel sequential dyadic die-rolling paradigm, we show that collaborative settings provide fertile ground for the emergence of corruption. In the main experimental treatment the outcomes of the two players are perfectly aligned. Player A privately rolls a die, reports the result to player B, who then privately rolls and reports the result as well. Both players are paid the value of the reports if, and only if, they are identical (e.g., if both report 6, each earns €6). Because rolls are truly private, players can inflate their profit by misreporting the actual outcomes. Indeed, the proportion of reported doubles was 489% higher than the expected proportion assuming honesty, 48% higher than when individuals rolled and reported alone, and 96% higher than when lies only benefited the other player. Breaking the alignment in payoffs between player A and player B reduced the extent of brazen lying. Despite player B's central role in determining whether a double was reported, modifying the incentive structure of either player A or player B had nearly identical effects on the frequency of reported doubles. Our results highlight the role of collaboration—particularly on equal terms—in shaping corruption. These findings fit a functional perspective on morality. When facing opposing moral sentiments—to be honest vs. to join forces in collaboration—people often opt for engaging in corrupt collaboration. PMID:26261341

  17. Transparency, Corruption, and Democratic Institutions

    Directory of Open Access Journals (Sweden)

    Graham Hubbs

    2014-01-01

    Full Text Available This essay examines some of the institutional arrangements that underlie corruption in democracy. It begins with a discussion of institutions as such, elaborating and extending some of John Searle’s remarks on the topic. It then turns to an examination of specifically democratic institutions; it draws here on Joshua Cohen’s recent Rousseau: A Free Community of Equals. One of the central concerns of Cohen’s Rousseau is how to arrange civic institutions so that they are able to perform their public functions without being easily abused by their members for individual gain. The view that Cohen sketches on behalf of Rousseau offers a clear framework for articulating institutional corruption in democracy. With this account of democratic institutions in place, the essay turns the discussion to the role of transparency in deterring institutional corruption. The basic thought here is perhaps unsurprising: to ensure that a democratic institution is serving its public function and not being manipulated for self-interested gain, its activities must be subject to public scrutiny, and so these activities must be transparent to the public. Saying this makes the role of transparency in a well-functioning democracy clear, but it does not settle how transparency is to be realized. The essay argues that transparency can be realized in a democracy only by an extra-governmental institution that has several of the familiar features of the press. If this is correct, it follows that in its design and in many, though not all, of its activities, WikiLeaks provides a contemporary example of such an institution.

  19. Individual and Institutional Corruption in European and US Healthcare: Overview and Link of Various Corruption Typologies.

    Sommersguter-Reichmann, Margit; Wild, Claudia; Stepan, Adolf; Reichmann, Gerhard; Fried, Andrea

    2018-03-23

    In recent years, the fight against healthcare corruption has intensified. Estimates from the European Healthcare Fraud and Corruption Network calculate an approximate €56 billion annual loss to Europe as a result of corruption. To promote understanding of the complexity and interconnection of corrupt activities, we aim to present healthcare-related corruption typologies of the European Union and European Healthcare Fraud and Corruption Network. We subsequently link them to the typology of individual and institutional corruption introduced by Dennis Thompson in the context of investigating misconduct of US Congressional members. According to Thompson, individual corruption is the personal gain of individuals performing duties within an institution in exchange for nurturing private interests, while institutional corruption pertains to the failure of the institution in directing the individual's behaviour towards the achievement of the institution's primary purpose because the institutional design promotes the pursuit of individual goals. Effective anti-corruption activities not only require the enactment of anti-corruption laws but also the monitoring and, where appropriate, revision of institutional frameworks to prevent the undermining of the primary purposes of health systems or institutions. To gain further understanding of the similarities and differences of the three typologies, prime examples of corrupt activities in the health sector in the European Union and USA (along with their potential remedies) are provided. Linking corruption cases to Thompson's typology revealed that many corrupt activities may show elements of both individual and institutional corruption because they are intertwined, partly overlap and may occur jointly. Hence, sanctioning individual actors only does not target the problem.

  4. Political Corruption as Deformities of Truth

    Directory of Open Access Journals (Sweden)

    Yann Allard-Tremblay

    2014-01-01

    Full Text Available This paper presents a conception of corruption informed by epistemic democratic theory. I first explain the view of corruption as a disease of the political body. Following this view, we have to consider the type of actions that debase a political entity of its constitutive principal in order to assess corruption. Accordingly, we need to consider what the constitutive principle of democracy is. This is the task I undertake in the second section where I explicate democratic legitimacy. I present democracy as a procedure of social inquiry about what ought to be done that includes epistemic and practical considerations. In the third section, I argue that the problem of corruption for a procedural conception of democracy is that the epistemic value of the procedure is diminished by corrupted agents’ lack of concern for truth. Corruption, according to this view, consists in two deformities of truth: lying and bullshit. These deformities corrupt since they conceal private interests under the guise of a concern for truth. In the fourth section, I discuss the difficulties a procedural account may face in formulating solutions to the problem of corruption.

  8. Political Corruption, Democratic Theory, and Democracy

    Directory of Open Access Journals (Sweden)

    Doron Navot

    2014-09-01

    Full Text Available According to recent conceptual proposals, institutional corruption should be understood within the boundaries of the institution and its purpose. Political corruption in democracies, prominent scholars suggest, is characterized by the violation of institutional ideals or behaviors that tend to harm democratic processes and institutions. This paper rejects the idea that compromises, preferences, political agreements, or consent can be the baseline of conceptualization of political corruption. In order to improve the identification of abuse of power, the concept of political corruption should not be related directly to democratic institutions and processes; rather, it should be related to ideals whose content is independent of citizens’ preferences, institutions and processes. More specifically, I articulate the relations between political corruption and the notion of subjection, and include powerful citizens in the category of political corruption. Yet, I also suggest redefining under what conditions agents are culpable for their motivations in promoting private gain. By doing this, we better realize how democratic institutions can be the source of corruption and not just its victims. Such a redefinition, I propose finally, is the basis for the distinction between individual and institutional corruption.

In the same time, the amount of money lost by businesses and the public sector to larger frauds increased last year to unthinkable limits. The shareholders expect the directors to take care to protect their company’s assets. This is why the financial controller has a very important role in each organization. The techniques to detect corruption or a fraud are developing every year. Thus, the introduction of computerized accounting has created the opportunities to conduct very comprehensive tests at relatively little cost. However, the fraudsters became more and more clever, and the controllers are responsible for the prevention and detection of fraud. The procedures that controllers should adopt with regard to fraud depend on the risk that fraud could occur and remain undetected and also the risk of that fraud impairing the truth and fairness of the statement.

  16. Three paradigms for the analysis of corruption

    2015-10-01

    Full Text Available In the last decades a growing awareness emerged of the relevance of corruption as an hidden factor which may negatively affect political and economic decision-making processes. In spite of a lively scientific debate there is no general consensus on a commonly accepted definition of what corruption is.The A. distinguishes three main paradigms, focusing on different (though not irreconcilable variables.The first is the economic paradigm, which usually takes the principal-agent model of corruption as its founding pillar. In this paradigm corruption is considered the outcome of rational individual choices, and its spread within a certain organization is influenced by the factors defining the structure of expected costs and rewards.A second approach – the cultural paradigm – looks at the differences in cultural traditions, social norms and interiorized values which shape individuals’ moral preferences and consideration of his social and institutional role. These are a leading forces that can push a corrupt public or private agent (not to violate legal norms.A third neo-institutional approach considers also mechanisms which allow the internal regulation of social interactions within corrupt networks, and their effects on individuals’ beliefs and preferences. Though the corrupt agreements cannot be enforced with legal sanctions, several informal, non-written rules, contractual provisos and conventions may regulate the corrupt exchange between agent and corruptor.The A. underlines that corruption is the outcome of a multitude of individual and collective choices which change public opinion towards corruption and its diffusion throughout the state, markets and civil society. There is no univocal recipe to deal with anti-bribery measures, since corruption is a complex and multifaceted phenomenon.Reforms aimed at dismantling systemic corruption have to be finely tuned against its hidden governance structures, i.e. its internal regulation of

    2015-06-01

    We inspect a possible clustering structure of the corruption perception among 134 countries. Using the average linkage clustering, we uncover a well-defined hierarchy in the relationships among countries. Four main clusters are identified and they suggest that countries worldwide can be quite well separated according to their perception of corruption. Moreover, we find a strong connection between corruption levels and a stage of development inside the clusters. The ranking of countries according to their corruption perfectly copies the ranking according to the economic performance measured by the gross domestic product per capita of the member states. To the best of our knowledge, this study is the first one to present an application of hierarchical and clustering methods to the specific case of corruption.

  18. Introduction: Institutional corruption and the pharmaceutical policy.

    Science.gov (United States)

    Rodwin, Marc A

    2013-01-01

    Today, the goals of pharmaceutical policy and medical practice are often undermined due to institutional corruption - that is, widespread or systemic practices, usually legal, that undermine an institution's objectives or integrity. In this symposium, 16 articles investigate the corruption of pharmaceutical policy, each taking a different look at the sources of corruption, how it occurs, and what is corrupted. We will see that the pharmaceutical industry's own purposes are often undermined. Furthermore, pharmaceutical industry funding of election campaigns and lobbying skews the legislative process that sets pharmaceutical policy. Moreover, certain practices have corrupted medical research, the production of medical knowledge, the practice of medicine, drug safety, the Food and Drug Administration's oversight of the pharmaceutical market, and the trustworthiness of patient advocacy organizations. © 2013 American Society of Law, Medicine & Ethics, Inc.

  19. Corruption and the Securitisation of Nature

    Directory of Open Access Journals (Sweden)

    Full Text Available This article considers corruption in Australia in relation to the exploitation and preservation of natural resources. In doing so, it examines issues pertaining to a proposed pulp mill and the forestry industry in Tasmania, the development of mining and ports in Queensland, and international agreements pertaining to deep-sea oil drilling in the Timor Sea. Corruption relating to the environment is interpreted in this article as implying both moral corruption and/or direct corruption. Gaining unfair advantage, protecting specific sectoral interests and over-riding existing environmental regulations are all features of the types of corruption associated with the exploitation of natural resources. The result is lack of transparency, a substantial democratic deficit, and expenditure of public monies, time and resources in support of environmentally and socially dubious activities.

    How well do corruption perception measures reflect actual levels of public sector corruption? Leading cross-national corruption perception measures have come under much theoretical and empirical scrutiny in recent years, with serious implications for the validity and reliability of the data...... in this ever growing sub-field. Critics argue that perceptions – in particular those of outside experts – do not reflect actual corruption in that they are far too ‘noisy’ or simply biased by external factors such as economic performance. Moreover, a number of recent empirical studies, focused on developing...... areas, have put forth evidence that outside expert assessments of corruption correspond little, if at all, with the experiences and views of actual citizens, and that such a lack of correspondence demonstrates pessimism for existing perception measures.

    We have analyzed the interplay between an externally added noise and the intrinsic noise of systems that relax fast towards a stationary state, and found that increasing the intensity of the external noise can reduce the total noise of the system. We have established a general criterion for the appearance of this phenomenon and discussed two examples in detail.

    2017-08-01

    A segmented mirror is one of the most promising solutions to build an extremely large aperture telescope to reveal the secrets of the universe. In this manuscript, we present a simultaneous angle alignment method for segmented mirrors. By taking the displayed sinusoidal pattern reflecting off the mirrors, the tip-tilt angles are measured with 0.8 μrad resolution for a flat mirror. Due to the efficient calculation using Fourier analysis, the total measurement time for seven flat mirrors is 0.07 s. In addition, a multiplexed sinusoidal pattern is adapted to resolve the intrinsic 2π ambiguity problem in a sinusoidal signal. The presented method can measure any number of segmented mirrors provided that the camera's field of view can cover them all simultaneously.

    1995-01-01

    Loose Part Monitoring System (LPMS) is one of the fundamental diagnostic tools installed in the nuclear power plants. In this paper, recovery process algorithm and model for the corrupted impact signal generated by loose parts is presented. The characteristics of this algorithm can obtain a proper burst signal even though background noise is considerably high level comparing with actual impact signal. To verify performance of the proposed algorithm, we evaluate mathematically signal-to-noise ratio of primary output and noise. The performance of this recovery process algorithm is shown through computer simulation

  4. Decision-Based Marginal Total Variation Diffusion for Impulsive Noise Removal in Color Images

    Directory of Open Access Journals (Sweden)

    Hongyao Deng

    2017-01-01

    Full Text Available Impulsive noise removal for color images usually employs vector median filter, switching median filter, the total variation L1 method, and variants. These approaches, however, often introduce excessive smoothing and can result in extensive visual feature blurring and thus are suitable only for images with low density noise. A marginal method to reduce impulsive noise is proposed in this paper that overcomes this limitation that is based on the following facts: (i each channel in a color image is contaminated independently, and contaminative components are independent and identically distributed; (ii in a natural image the gradients of different components of a pixel are similar to one another. This method divides components into different categories based on different noise characteristics. If an image is corrupted by salt-and-pepper noise, the components are divided into the corrupted and the noise-free components; if the image is corrupted by random-valued impulses, the components are divided into the corrupted, noise-free, and the possibly corrupted components. Components falling into different categories are processed differently. If a component is corrupted, modified total variation diffusion is applied; if it is possibly corrupted, scaled total variation diffusion is applied; otherwise, the component is left unchanged. Simulation results demonstrate its effectiveness.

    Tovar, A A; Casperson, L W

    1998-09-01

    Hermite-sinusoidal-Gaussian solutions to the wave equation have recently been obtained. In the limit of large Hermite-Gaussian beam size, the sinusoidal factors are dominant and reduce to the conventional modes of a rectangular waveguide. In the opposite limit the beams reduce to the familiar Hermite-Gaussian form. The propagation of these beams is examined in detail, and resonators are designed that will produce them. As an example, a special resonator is designed to produce hyperbolic-sine-Gaussian beams. This ring resonator contains a hyperbolic-cosine-Gaussian apodized aperture. The beam mode has finite energy and is perturbation stable.

    2003-04-01

    In this paper, a contribution is given to provide a tool to the recognition of sinusoidal signals with a particular reference to the field of pediatric hearing rehabilitation. To this purpose, a synthesis technique previously developed by the authors' is used to design a Cellular Neural Network for an Associative Memory able to compare submitted discrete-time sinusoidal signals with memorized ones. A robustness analysis of the synthesized associative memory is also developed both for noisy inputs and for parameter variations. Simulation results are then reported to illustrate the performances of the designed network.

  7. Anti-Corruption from Below. Social Movements Against Corruption in Late Neoliberalism

    Directory of Open Access Journals (Sweden)

    2018-01-01

    Full Text Available In the last decades, a growing awareness has emerged in progressive social movements about the relevance of corruption as a hidden factor that negatively influences political and economic decision-making processes in both liberal-democratic and authoritarian regimes. Rampant corruption has been denounced by social movements, which have developed specific diagnostic and prognostic frames as well as knowledge and practices for the social accountability of political and economic powers. This contribution maps some of the characteristics of civil society as anti-corruption actors, reflecting on the theoretical challenges they present for social movement theory and for research on corruption and anti-corruption. In order to understand the emergence and outcomes of these mobilizations against corruption, it bridges two bodies of literature which have only very rarely crossed paths: corruption studies and social movement studies. Departing from the traditional visions of anti-corruption from below within corruption studies, the article brings upon social movement studies in order to synthetize some of the main context, organizational forms and framing of (anti-corruption in today's contentious politics.

    2000-01-01

    A frequency sub-band based adaptive spectral subtraction algorithm is developed to remove noise from noise-corrupted speech signals. A single microphone is used to obtain both the noise-corrupted speech and the estimate of the statistics of the noise. The statistics of the noise are estimated during time frames that do not contain speech. These statistics are used to determine if future time frames contain speech. During speech time frames, the algorithm determines which frequency sub-bands contain useful speech information and which frequency sub-bands contain only noise. The frequency sub-bands, which contain only noise, are subtracted off at a larger proportion so the noise does not compete with the speech information. Simulation results are presented.

  9. Corruption in Mexico: A Historical Legacy

    Directory of Open Access Journals (Sweden)

    Nubia Nieto

    2014-06-01

    Full Text Available Among the many consequences of colonialism that are still present in postcolonial societies are corruption and the lack of strong institutions to fight against this phenomenon. What used to be unequal power relations between the colonizers and the colonies have been replaced by the dominance of the local elites over ordinary citizens, who have practically given the former a lot of leeway to commit acts of corruption with a sense of impunity and without regard for accountability. One case in point is Mexico which, in recent times, has made international news headlines because of incidences of drug trafficking, violence, and corruption in the country. This article delineates the historical relationship between corruption and colonialism, and how these forces have shaped Mexican culture. The discussion tackles the presence of corruption since the colonial times to the present. Specif ically, it starts with an analysis of the role of colonialism in the incidence of corruption. Secondly, it describes the discrepancy between the law and its application, from the arrival of the Spanish colonizers to the present. Finally, it examines the cultural, educational, and social challenges that should be addressed in order to surmount the colonial legacies that breed corruption.

  10. Automatic fringe enhancement with novel bidimensional sinusoids-assisted empirical mode decomposition.

    Science.gov (United States)

    Wang, Chenxing; Kemao, Qian; Da, Feipeng

    2017-10-02

    Fringe-based optical measurement techniques require reliable fringe analysis methods, where empirical mode decomposition (EMD) is an outstanding one due to its ability of analyzing complex signals and the merit of being data-driven. However, two challenging issues hinder the application of EMD in practical measurement. One is the tricky mode mixing problem (MMP), making the decomposed intrinsic mode functions (IMFs) have equivocal physical meaning; the other is the automatic and accurate extraction of the sinusoidal fringe from the IMFs when unpredictable and unavoidable background and noise exist in real measurements. Accordingly, in this paper, a novel bidimensional sinusoids-assisted EMD (BSEMD) is proposed to decompose a fringe pattern into mono-component bidimensional IMFs (BIMFs), with the MMP solved; properties of the resulted BIMFs are then analyzed to recognize and enhance the useful fringe component. The decomposition and the fringe recognition are integrated and the latter provides a feedback to the former, helping to automatically stop the decomposition to make the algorithm simpler and more reliable. A series of experiments show that the proposed method is accurate, efficient and robust to various fringe patterns even with poor quality, rendering it a potential tool for practical use.

    Government plays an important role in nation economic growth. Nevertheless, there are still many occurrences of government officers abusing their offices to do an act of corruption. In this order, the central government should pay attention to every area in the nation to avoid corruption case. Meanwhile, the news media always constantly preach about corruption case, this makes the news media relevant for being one of the sources of measurement of corruption perception index (CPI). It is required to map the corruption case in Indonesia so the central government can pay attention to every region in Indonesia. To develop the mapping system, researchers use Naïve Bayes Classifier to classify which news articles talk about corruption and which news articles are not, before implementing a Naïve Bayes Classifier there are some text processing such as tokenizing, stopping, and stemming.

    Full Text Available An aircraft wing needs to display different mechanical behavior in different directions. 1- stiffness in the spanwise (transverse to the corrugation direction which enables the aerodynamic and inertial loads to be carried. 2- compliance in the chordwise (corrugation direction which would allow shape changes and increases in surface area; whereas a corrugated sheet due to their special geometry has potential to use in morphing applications. Therefore, in this paper the mechanical behaviour of quasi-sinusoidal corrugated composites is studied by commercial FEM software ABAQUS and a simple analytical model which is used for the initial stiffness of the quasi-sinusoidal corrugated composites (Yokozeki model. The elongation and effective stiffness in longitudinal and transverse directions of quasi-sinusoidal  corrugated  skins  and fat  composites  are  calculated  and  compared together.  Using  frst  and  second  Castigliano’s  theorem  and  Bernoulli-Euler  beam theorem can be used to calculate the defection and rotational angle of a beam (sheet. In this research, different dimensions of quasi-sinusoidal element for unidirectional and woven composites of E-glass/epoxy are investigated. FEM results and analytical model are compared together. Then, the analytical model is validated by experimental results of plain woven E-glass/epoxy composites. The results of FEM, experimental and analytical simulations show that how a corrugated composite can afford with certainty larger deformation than the fat composite in using this analytical model to predict the mechanical behavior of quasi-sinusoidal corrugated composites. It was found that the corrugated composites display extremely high anisotropic behavior and have high  tensile and fexural stiffness  in  transverse direction while exhibiting  low stiffness in longitudinal direction of corrugation.

First, despite the seriousness of the phenomenon of corruption, there is a paucity of rigorous empirical research of corruption, particularly tax corruption, in Vietnam. Secondly, ineffective control of corruption is viewed as a cause of Vietnam’s recent total factor productivity (TFP) slowdown or its poor industrial policy, both of wh...

    Full Text Available The paper gives an outline of Nigeria’s experience on corruption in the context of poverty and Development. It discusses the effects of corruption which are rooted in the political and economic situation of the polity. The challenge of corruption is at the root of our underdevelopment .It has become so pervasive that many essential public projects for which vast sums of money have been paid to concerned contractors have been abandoned. And when such public projects have been completed, their costs are always higher in comparison with the costs of similar projects in other countries. In Nigeria corruption stifle economic growth, reduce economic efficiency and development despite the enormous resources in the country. It depends essentially on data from secondary sources such as books, journal articles, government publications, among other relevant documents. The data were analyzed qualitatively using the descriptive analytical method in order to achieve the primary objective of the paper.

  4. History gone wrong: Rousseau on corruption

    Directory of Open Access Journals (Sweden)

    Kroupa Gregor

    2013-01-01

    Full Text Available It can be said that Rousseau is one of the most acute thinkers of the corruption of civilization. In fact, the Second Discourse and the Essay on the Origins of Languages could be read as elaborate analyses of advanc­ing social and cultural decline inasmuch as mankind is continually moving away from the original state of natural innocence. But Rousseau’s idea of corruption is not straightforward. I try to show that in the Essay, Rousseau emphasizes the natural causes for corruption. I argue that an opposition between necessity and contingency, which more accurately represents the two modes operating in Rousseau’s doctrine, should replace the standard nature/culture divide. The contingency of natural catastrophes is found to be ultimately responsible for the corruption in the social realm, which is therefore largely driven by natural causes.

    This paper demonstrates that high and rising corruption increases income inequality and poverty by reducing economic growth, the progressivity of the tax system, the level and effectiveness of social spending, and the formation of human capital, and by perpetuating an unequal distribution of asset ownership and unequal access to education. These findings hold for countries with different growth experiences, at different stages of development, and using various indices of corruption. An import...

  11. CORRUPTION IN SOUTH AFRICA: GENESIS AND OUTLOOK

    Directory of Open Access Journals (Sweden)

    Natasha Georgieva Hadji Krsteski

    2017-10-01

    Full Text Available Corruption in South Africa includes the private use of public resources, bribery and improper favouritism. South Africa scored 45 points out of 100 on the 2016 Corruption Perceptions Index reported by Transparency International. Corruption Index in South Africa averaged 46.97 Points from 1996 until 2016, reaching an all-time high of 56.80 Points in 1996 and a record low of 41 Points in 2011. A tenderpreneur is common corruption in South Africa. It is an individual who enriches themselves through corrupting the awarding of government tender contracts, mostly based on personal connections and corrupt relationships - although outright bribery might also take place - and sometimes involving an elected or politically appointed official (or his or her family members holding simultaneous business interests. This is often accompanied by overcharging and shoddy workmanship. BEE-fronting is an abuse of the rules governing Black Economic Empowerment (BEE, where qualifying persons are given a seat on the Board of Directors of a company while having no decision-making power in the company, in order to qualify the company for government contracts in terms of BEE.

  12. Bioethics and corruption: a personal struggle.

    Science.gov (United States)

    Blasszauer, Bela

    2013-01-01

    The author attempts to give a general picture of corruption, especially in the area of healthcare. Corruption ranges from fraud, through deceit, bribery and dehumanisation, to immeasurable moral decay. As a bioethicist who has challenged corruption in various ways, the author approaches this worldwide plague mainly on the basis of his personal experience. He does not offer a recipe for successfully combating corruption, but tries to provide some ways and means to fight immorality without self-defeat. Bioethics is not a discipline whose task is to investigate, expose, or punish corrupt people. A number of agencies exist for this "noble" job. Nevertheless, an ethics teacher should not be completely indifferent to obvious and harmful immoral behaviour, regardless of his/her personal compulsions. It is not the "patient rights" that threaten the prestige of the medical profession; it is rather the bad apples that infiltrate the moral mission of this esteemed work. It seems that the hardest challenges in the struggle against corruption are bad laws-laws that provide loopholes and immunity to immoral dealings. In a stable, strong democracy, morally unfounded laws can, and will be changed. Where real democracy exists, they would not even have come into effect.

  13. Fighting corruption – a philosophical approach

    Directory of Open Access Journals (Sweden)

    Schalk W. Vorster

    2013-07-01

    Full Text Available Corruption has reached astounding proportions in South Africa. The purpose of this article is to contribute to philosophical approaches aimed at combating corruption. In considering punishment for acts of corruption the most common approach is based on the philosophical theory of consequentialism, which allows only consideration of the consequences of corrupt acts. Ideally, cognisance should be taken of the norms in question, especially those norms demanding the judicious execution of obligations. It was, however, found that the Kantian categorical imperative presupposes an ideal rational society. The imperative has to be ‘softened’ by also allowing for enquiry about the corruptor’s personal circumstances, in the light of Christ’s love commandment. This article highlights the most prominent attributes of two important philosophical theories applicable to the study of corruption, namely utilitarianism (a variant of consequentialism and deontology. It is argued that qualified deontological and utilitistic approaches hold the best promise to curb corruption in the long run. The conclusion is that the state will urgently have to attend to the social context by revitalising programmes of ‘social renewal’, based on effective application of the law, the provision of adequate education and the eradication of poverty. There is also an urgent need for the ‘moral renewal’ of the entire population, focused on Christian values, operationalised within the context of the South Africa of today. Herein lies a massive task for the church.

  14. Nonlocal response functions for predicting shear flow of strongly inhomogeneous fluids. I. Sinusoidally driven shear and sinusoidally driven inhomogeneity.

    We present theoretical expressions for the density, strain rate, and shear pressure profiles in strongly inhomogeneous fluids undergoing steady shear flow with periodic boundary conditions. The expressions that we obtain take the form of truncated functional expansions. In these functional expansions, the independent variables are the spatially sinusoidal longitudinal and transverse forces that we apply in nonequilibrium molecular-dynamics simulations. The longitudinal force produces strong density inhomogeneity, and the transverse force produces sinusoidal shear. The functional expansions define new material properties, the response functions, which characterize the system's nonlocal response to the longitudinal force and the transverse force. We find that the sinusoidal longitudinal force, which is mainly responsible for the generation of density inhomogeneity, also modulates the strain rate and shear pressure profiles. Likewise, we find that the sinusoidal transverse force, which is mainly responsible for the generation of sinusoidal shear flow, can also modify the density. These cross couplings between density inhomogeneity and shear flow are also characterized by nonlocal response functions. We conduct nonequilibrium molecular-dynamics simulations to calculate all of the response functions needed to describe the response of the system for weak shear flow in the presence of strong density inhomogeneity up to the third order in the functional expansion. The response functions are then substituted directly into the truncated functional expansions and used to predict the density, velocity, and shear pressure profiles. The results are compared to the directly evaluated profiles from molecular-dynamics simulations, and we find that the predicted profiles from the truncated functional expansions are in excellent agreement with the directly computed density, velocity, and shear pressure profiles.

  18. Dynamics of the Josephson multi-junction system with junctions characterized by non-sinusoidal current - phase relationship

    International Nuclear Information System (INIS)

    Abal'osheva, I.; Lewandowski, S.J.

    2004-01-01

    It is shown that the inclusion of junctions characterized by non-sinusoidal current - phase relationship in the systems composed of multiple Josephson junctions - results in the appearance of additional system phase states. Numerical simulations and stability considerations confirm that those phase states can be realized in practice. Moreover, spontaneous formation of the grain boundary junctions in high-T c superconductors with non-trivial current-phase relations due to the d-wave symmetry of the order parameter is probable. Switching between the phase states of multiple grain boundary junction systems can lead to additional 1/f noise in high-T c superconductors. (author)

    2012-11-01

    Full Text Available Corruption is divided into small low-level corruption and high-level corruption. Small level little corruption is defined as the area of corruption which does not prejudice the interests of the majority of individuals. This category can be covered by a health care professional, the corruption of a clerk, etc through their decisions is an individual or group of individuals at the expense of others, but this kind of injustice is limited in time and space. Corruption, means high-level corruption of a dignitary, clerk, etc. This kind of corruption and the main effect over the entire State characteristic and the individuals who compose it. The consequences of this kind of corruption can translate into direct and indirect costs that will be supported in the end by all taxpayers. The objectives of corruption are double: profit and power. The international economic crisis has its origin in the manifestations of high level corruption in the governments of different countries. All the state now have to fight against corruption in order to settle new rules to avoid the effects af the crisis and to prevent a deepening of this crisis with devastating effects upon tha population. Here we try to emphasize the importance that we all should give corruption and measures had to be taken by everyone.

    Full Text Available This paper presents the correlation of factors that determine the quality of asymmetric quasi-sinusoidal output current and dynamic losses in the switches of the current generator circuit. The operating mode of the generator was obtained, especially of its power circuit elements, where combination of acceptable output current quality with relatively small dynamic losses in switches and mass-dimensional parameters of the inductor are provided. Achieved results can be used in designing this type of generators.

  3. Acceptance of Corrupt Acts: a Comparative Study of Values Regarding Corruption in Europe

    Directory of Open Access Journals (Sweden)

    IOANA POP

    2012-07-01

    Full Text Available The present contribution seeks to explain variation in the degree of acceptance of corrupt acts by taking into consideration bothindividual characteristics and societal ones. We used a large dataset covering 43 European countries and employed multi-levelmodels in order to disentangle the compositional and contextual effects. Our main findings suggest that young single Europeanswith no occupation but with material possibilities are more likely to consider corrupt acts as being acceptable. The presence of apartnership and of children as well as high confidence in the governance bodies of a country makes corrupt acts less acceptable.In addition, the society where one lives is also important: individuals living in the former soviet countries display on averagehigher acceptance of corrupt acts than individuals living in the former communist block or in long established democracies. Thisconclusion holds also after controlling for how widespread corruption is in these countries or how high their income inequality is.

  4. Vibration Analysis of Composite Beams with Sinusoidal Periodically Varying Interfaces

    Science.gov (United States)

    Li, Botong; Liu, Chein-Shan; Zhu, Liangliang

    2017-12-01

    As an increasing variety of composite materials with complex interfaces are emerging, we develop a theory to investigate composite beams and shed some light on new physical insights into composite beams with sinusoidal periodically varying interfaces. For the natural vibration of composite beams with continuous or periodically varying interfaces, the governing equation has been derived according to the generalised Hamiltonian principle. For composite beams having different boundary conditions, we transform the governing equations into integral equations and solve them by using the sinusoidal functions as test functions as well as the basis of the vibration modes. Due to the orthogonality of the sinusoidal functions, expansion coefficients in closed form can be found. Therefore, the proposed iterative schemes, with the help of the Rayleigh quotient and boundary functions, can quickly find the eigenvalues and free vibration modes. The obtained natural frequencies agree well with those obtained using the finite element method. In addition, the proposed method can be extended easily to laminated composite beams in more general cases or complex components and geometries in vibration engineering. The effects of different material properties of the upper and lower components and varying interface geometry function on the frequency of the composite beams are examined. According to our investigation, the natural frequency of a laminated beam with a continuous or periodically varying interface can be changed by altering the density or elastic modulus. We also show the responses of the frequencies of the components to the varying periodic interface.

  5. Increased sinusoidal volume and solute extraction during retrograde liver perfusion

    International Nuclear Information System (INIS)

    Bass, N.M.; Manning, J.A.; Weisiger, R.A.

    1989-01-01

    Retrograde isolated liver perfusion has been used to probe acinar functional heterogeneity, but the hemodynamic effects of backward flow have not been characterized. In this study, extraction of a long-chain fatty acid derivative, 12-N-methyl-7-nitrobenzo-2-oxa-1,3-diazol-amino stearate (12-NBDS), was greater during retrograde than during anterograde perfusion of isolated rat liver. To determine whether hemodynamic differences between anterograde and retrograde perfused livers could account for this finding, the hepatic extracellular space was measured for both directions of flow by means of [ 14 C]sucrose washout during perfusion as well as by direct measurement of [ 14 C]sucrose entrapped during perfusion. A three- to fourfold enlargement of the total hepatic extracellular space was found during retrograde perfusion by both approaches. Examination of perfusion-fixed livers by light microscopy and morphometry revealed that marked distension of the sinusoids occurred during retrograde perfusion and that this accounts for the observed increase in the [ 14 C]sucrose space. These findings support the hypothesis that maximum resistance to perfusate flow in the isolated perfused rat liver is located at the presinusoidal level. In addition, increased transit time of perfusate through the liver and greater sinusoidal surface area resulting from sinusoidal distension may account for the higher extraction of 12-NBDS and possibly other compounds by retrograde perfused liver

    2012-12-01

    Full Text Available This paper investigates the impact of corruption on economic growth in the Italian Regions. We estimate a dynamic growth model for the period 1980-2004 addressing both the potential bias of the measures of corruption and the endogeneity between corruption and economic development. We find strong evidence of a negative correlation between corruption and growth. Moreover, since government intervention has been traditionally used to reduce income differentials between the Northern and the Southern regions, we also analyze the interaction between corruption and government expenditure. Our results indicate that corruption undermines the positive impact that public expenditures have on economic growth.

    Full Text Available Corruption is a problem that continues to plague developed and developing countries worldwide. Previous studies have explored the negative implications of corruption on several aspects of human development, but, despite its serious and long-lasting consequences, the impact of corruption on educational outcomes has started to receive attention only in recent years. This study empirically investigates the relationship between corruption and educational outcomes, using a sample of 50 countries. Study findings show that corruption is negatively associated with educational outcomes, after controlling for other variables, and suggest that continued efforts be made to control corruption.

  8. On Capability Approach, Poverty and Corruption

    Directory of Open Access Journals (Sweden)

    Daojiu Hu

    2014-04-01

    Full Text Available The core of development is to face up with the challenge of the issue of poverty, which directly is associated with the ultimate goal of social, political and economic development. If the poverty has not been properly handled, development will be inefficient and unsustainable. This paper briefly indicates the main idea of Amartya Sen’s capability approach, then utilizing the approach to analyze poverty and the bottleneck in dealing such issues. It illustrates the inter-relationship of capability, poverty and corruption, and demonstrates that corruption is both the cause and the consequence of poverty and the failure of capability. When there corruption comes, the essential power to alleviate and eliminate poverty such as political accountability, transparency, engagement and openness are all spoiled and even wiped off. Political accountability, transparence, engagement are of great importance to both anti-corruption and poverty and promotion of capability. Economic aid for the poor and needy should be reinforced by fostering and promoting the capability of the poor and needy, so that the purpose of eliminating poverty and corruption could be achieved.

    2017-11-01

    Full Text Available This special issue gathers and enlarges upon papers that were first presented at the interdisciplinary ‘Corruption Downunder’ symposium held at the University of Auckland in November 2015; most of the papers published here stem from the lively and collegial discussions at the symposium. At that time New Zealand was authoritatively measured (by Transparency International to be Number 2 ‘least corrupt’ nation in the world; it is now tied at Number 1 with Denmark. What this rank, as measured by Transparency International’s Corruption Perceptions Index (CPI, actually counts for is something that we explore in this special issue. On the face of it, it would seem perverse to be focusing on corruption in such a place as New Zealand. With its larger northern neighbour Australia listed at a respectable 11th out of 175 that same year (2014 data, why would a bunch of academics want to engage in serious discussions about the problem of corruption ‘downunder’? New Zealand has never been ranked outside of the top four, and has been ranked Number 1 in a total of 12 out of 22 years since the survey began. Australia is generally ranked in the top ten and has never been out of the top 13 least corrupt countries since the survey began.

  10. China's Land Market Auctions: Evidence of Corruption?

    Science.gov (United States)

    Cai, Hongbin; Henderson, J Vernon; Zhang, Qinghua

    2013-01-01

    This paper studies the urban land market in China in 2003-2007. In China, all urban land is owned by the state. Leasehold use rights for land for (re)development are sold by city governments and are a key source of city revenue. Leasehold sales are viewed as a major venue for corruption, prompting a number of reforms over the years. Reforms now require all leasehold rights be sold at public auction. There are two main types of auction: regular English auction and an unusual type which we call a "two stage auction". The latter type of auction seems more subject to corruption, and to side deals between potential bidders and the auctioneer. Absent corruption, theory suggests that two stage auctions would most likely maximize sales revenue for properties which are likely to have relatively few bidders, or are "cold", which would suggest negative selection on property unobservables into such auctions. However, if such auctions are more corruptible, that could involve positive selection as city officials divert hotter properties to a more corruptible auction form. The paper finds that, overall, sales prices are lower for two stage auctions, and there is strong evidence of positive selection. The price difference is explained primarily by the fact that two stage auctions typically have just one bidder, or no competition despite the vibrant land market in Chinese cities.

  12. EDUCATION CORRUPTION AND TEACHER ABSENTEEISM IN NIGERIA

    Directory of Open Access Journals (Sweden)

    John N. N. Ugoani

    2016-05-01

    Full Text Available Education corruption displays ample evidence that warrants inefficiencies and absenteeism among teachers. Teachers are the transmitters of knowledge who help to ensure that children learn, they are role models and in most rural communities they are the most educated and respected personages. High teacher absenteeism can exist when teachers have very low levels of motivation to work and little commitment to the profession, and when there is lack of accountability in the education sector. Because of the importance of education to society, international bodies emphasize the need for attracting, developing and retaining effective teachers. It is necessary to state that reducing official corruption in the education sector, promoting teacher welfare, designing better systems for monitoring and reducing invalid absences are among the critical measures of combating teacher absenteeism. The survey research design was used for the study and the result supports that education corruption has significant positive relationship with teacher absenteeism

According to WEF 2014 Global Risk Report, the bureaucracy has a high level in European countries and appreciation is growing that high historical rates of economic progress, especially those experienced by emerging markets, may not be sustainable in the future.  Corruption is growing in a changing global environment and is considered one of the most important geopolitical risks. Most of the time, corruption is associated with fraud and money laundering. European growing cities and public administration have a strong influence over bureaucracy in public sector accounting and more time to process the accounting and fiscal information.

    Information on the global risk factors of children mortality is crucial to guide global efforts to improve survival. Corruption has been previously shown to significantly impact on child mortality. However no recent quantification of its current impact is available. The impact of corruption was assessed through crude Pearson's correlation, univariate and multivariate linear models coupling national under-five mortality rates in 2008 to the national "perceived level of corruption" (CPI) and a large set of adjustment variables measured during the same period. The final multivariable model (adjusted R(2)= 0.89) included the following significant variables: percentage of people with improved sanitation (p.valueCorruption Perception Index (p.valuecorruption) was associated with an increase in the log of national under-five mortality rate of 0.0644. According to this result, it could be roughly hypothesized that more than 140000 annual children deaths could be indirectly attributed to corruption. Global response to children mortality must involve a necessary increase in funds available to develop water and sanitation access and purchase new methods for prevention, management, and treatment of major diseases drawing the global pattern of children deaths. However without paying regard to the anti-corruption mechanisms needed to ensure their proper use, it will also provide further opportunity for corruption. Policies and interventions supported by governments and donors must integrate initiatives that recognise how they are inter-related.

    Full Text Available Corporate security should commit to ethical management and raising the quality of companies and markets through improving cooperation and transparency by applying anticorruption measures such as accepting a code of ethics; respect and follow international business principles for dealing with bribery; improve their transparency - via access to information; involvement in politics to protect persons who disclose corruption cases; and improving corporate governance - through active mutual discussions on adjustment of legal regulations. Research methods used in the paper are: qualitative analysis of secondary data obtained from relevant institutions. Results obtained from the survey include fighting corruption in corporations must find a unique solution that is long-term strategy developed transparent society crucial criteria and principles to meet the political criteria by the fulfillment of anti-corruption standards; it requires continuous cooperation of public and private sector, NGOs and the general corpus of all stakeholders in the country against corruption; the lack of a legal framework or platform for establishing public and private partnerships, is an important factor for anti-corruption measures to improve corporate governance; mechanisms for cooperation does not seem sufficiently developed between the public, private, political and civil society; the most important factor to tackle corruption is to adopt a law on public prosecutors and determination of higher norms and standards. Conclusions drawn from the survey: in the area of pre-trial procedure requires shifting responsibilities of Interior Ministry body training in the area of the judicial system; it is necessary to change the Criminal Code and Criminal Procedure Code by changing certain legal provisions which refer to the Agency for money laundering SCCP, a financial police and overall legislation.

  16. Forms of corruption in the middle ages

    2012-01-01

    Full Text Available The paper continues the story of corruption as a socially harmful phenomenon that affected all societies, from ancient times, through mediaeval times, to modern age. Although the concept of corruption changed in the course of history, the essence has remained the same: it encompasses the abuse of power, corruption, bribery, and offering gratuities in exchange for favors. We shall here focus on the manifestations of corruption in the Middle Ages, the period which coincided with the feudal socio-economic formation, both in its western European variety and in the Byzantine type of feudal society. In the twelfth century, the Byzantine emperors introduced the practice of granting property in land or some other source of income - pronoia - to prominent individuals as a reward for their merits. In contrast, what could be observed from the very beginning in barbarian countries, which were established in the territory of the former Western Roman Empire, were the classic vassal relations, where a fief presented the foundation of the medieval social order; it was land property which the feudal lord (suzerain granted to his vassals (military commanders and units to enjoy, manage, but not control independently. By giving land property - a pronoia or fief to a pronoiario or vassal, the feudal lord (suzerain, in a way, 'bought' their personal loyalty. Particularly conductive to corruption was the hierarchically arranged and ramified bureaucratic apparatus of the mediaeval state. Although the Byzantine highest-ranking bureaucracy was paid for their work, their arbitrariness, bribery, coarseness, and incompetence resulted in strengthening corruption. On the other hand, the greatest influence on the kings in the barbaric mediaeval states was exerted by their commanders (dukes and entourage, who often selfishly abused the benefits bestowed upon them by the kings. Polybius' statement that 'the government has made people prone to bribery and greedy' proved to be

    2013-12-01

    Full Text Available Globalization has led to the fact that corruption in one country can affect the situation in other states. A number of top managers worldwide who are willing to pay bribes to keep or expand their business is increasing. However, the most common and dangerous corruption is in the government structures and corruption that associated with the use of administrative resources. The level of corruption in Ukraine is very high and remained stable for the past ten years. One of the factors of increasing corruption in Ukraine is considered the problem of political leadership. Using the Y.Engvalya theory of corruption allows re-evaluating mass and rationality of what is happening, indicates the fallacy of traditionally definition of corruption as unacceptable for majority. Existing corruption model today can be recognized as a widespread one, which significantly increases the role of political leadership. Implementation of new management standards is an important task for many states.

    Full Text Available For so long, development theories and practices have either deliberately neglected or simply overlooked the possible interconnections between religion, culture and the attainment of development goals. Against this background, this article reviews the literature on corruption, as a major factor of underdevelopment in Nigeria, particularly as it relates to religion and culture in the country. In its analysis, this article argues that corruption in Nigeria, especially in view of the country’s multi-ethnic and multi-religious status, must be conceived as a phenomenon transcending legal, political and economic boundaries. The study adopts an interpretative and descriptive methodology for its analysis.

    This paper shows empirically that 'privatization' in the energy, telecommunications, and water sectors, and the introduction of independent regulators in those sectors, have not always had the expected effects on access, affordability, or quality of services. It also shows that corruption leads to adjustments in the quantity, quality, and price of services consistent with the profit-maximizing behavior that one would expect from monopolies in the sector. Finally, our results suggest that privatization and the introduction of independent regulators have, at best, only partial effects on the consequences of corruption for access, affordability, and quality of utilities services.

    Betting exchanges allow punters to bet on a horse to lose a race. This, many argue, has opened up the sport to a new form of corruption, where races will be deliberately lost in order to profit from betting. We examine whether anecdotal evidence of the fixing of horses to lose—of which there are many examples—is indicative of wider corruption. Following a “forensic economics” approach, we build an asymmetric information model of exchange betting and take it to betting data on 9,560 races run ...

    The causes and consequences of corruption have attracted much attention in recent years by both academics and policy makers. Central in the discussion on the impact of corruption are perception-based indices. While informative, these indices are ordinal in nature and hence provide no indication of how much economic loss is attributed to corruption. Arguably, this shortcoming is rooted in the lack of a structural model. This is the issue addressed in this paper. By treating corruption as a lat...

While politicians pursue corruption rents that reduce the provision of public goods and sacrifice citizen's welfare, they are also concerned about the political support of citizens to maintain their political power. When inequality among citizens is large, political support is less sensitive to corruption. Therefore, large inequality increases corruption and impedes econom...

    We show that the motion of individual red blood cells in an oscillating moderate shear flow is described by a nonlinear system of three coupled oscillators. Our experiments reveal that the cell tank treads and tumbles either in a stable way with synchronized cell inclination, membrane rotation and hydrodynamic oscillations, or in an irregular way, very sensitively to initial conditions. By adapting our model described previously, we determine the theoretical diagram for the red cell motion in a sinusoidal flow close to physiological shear stresses and flow variation frequencies and reveal large domains of chaotic motions. Finally, fitting our observations allows a characterization of cell viscosity and membrane elasticity.

    Directory of Open Access Journals (Sweden)

    Madelijne Gorsira

    2018-02-01

    Full Text Available The aim of this research was to examine how organizational and individual factors, in concert, shape corruption. We examined whether the ethical climate of organizations is related to corruption, and if so, whether it affects corruption through individual motives for corruption. A large-scale questionnaire study was conducted among public officials (n = 234 and business employees (n = 289 who were in a position to make corrupt decisions. The findings suggest that public and private sector employees who perceive their organizational climate as more egoistic and less ethical are more prone to corruption. This relationship was fully mediated by individual motives, specifically by personal and social norms on corruption. These results indicate that employees who perceive their organization’s ethical climate as more egoistic and less ethical experience weaker personal and social norms to refrain from corruption, making them more corruption-prone. Hence, strategies addressing the interplay between organizational factors and individual motives seem promising in curbing corruption. To effectively withhold employees from engaging in corruption, organizations could deploy measures that strengthen an organizations’ ethical climate and encourage ethical decision-making based on concern for the wellbeing of others, as well as measures increasing the strength of personal and social norms to refrain from corruption.

    Punishment is widely recognized as a potential promoter in sustaining or even enhancing public cooperation, but it meanwhile induces the problem of second-order free-riders. Particularly, recent evidence shows that costly punishment can be maintained if punishers may engage in corruption. However, how to reduce or eliminate incidents of corruption has been the enduring conundrum in human society. As power asymmetries are associated with hierarchies, we investigate how costly punishment affects the evolution of cooperation in the cases without and with corruption control. In the absence of corruption control, altruistic punishers are incapable of punishing corrupt punishers. Corrupt punishment maintains civilian cooperation but undermines the evolution of altruistic punishment. Otherwise, altruistic punishers can enforce symmetrical or asymmetrical punishment on both corrupt punishers and civilian defectors. In this case, both civilian cooperation and altruistic punishment can be promoted. And as an instrument of corruption control, the policy of asymmetrical punishment is more effective in fostering public cooperation and improving social welfare than symmetrical punishment. Moreover, no matter whether corruption control is considered or not, spiteful corruption that non-cooperative punishers penalize defectors is a more effective form for enhancing cooperation compared with bribery. Our work may thus offer an insight into the effects of corruption on public cooperation and the policy of anti-corruption. Copyright © 2018 Elsevier Ltd. All rights reserved.

  2. Enterprises Dealing with Corruption: A Microeconomic Analysis

    Directory of Open Access Journals (Sweden)

    Ermira Hoxha Kalaj

    2015-03-01

    Full Text Available This article focuses on survey data and qualitative evidence from Albanian manufacturing firms to examine the scale and consequences of corruption and tax evasion at the enterprise level. It discusses the costs and benefits from the entrepreneur’s perspective. The vector of covariates includes information about; use of external finance, policy influence, experience of corruption, firms size and ownership structure. To control for differences in the availability of collateral, the proportion of the fixed assets is included. The models used in the paper are probit where the dependent variable is binary and ordered probit where the dependent variable is categorical and orderable. Empirical results show that manufacturing firms operating in an environment in which tax evasion is more prevalent are more likely to suffer demands for bribes from corrupt officials. The regression analysis shows that tax evasion is a matter of degree and that is not limited to small and medium-sized enterprises. Even quite large firms acknowledge concealing part of their sales from tax authorities. Enterprises that are evading taxes are less likely to obtain an external audit. In addition, the data predict that corruption and tax evasion is more likely to occur when the principal owner is male rather than female. Moreover, findings show that the main effect of the separation of ownership on the likelihood of bribery is insignificant.

  3. Cycle of Bad Governance and Corruption

    Directory of Open Access Journals (Sweden)

    Mohammed Nuruddeen Suleiman

    2015-03-01

    Full Text Available This article argues that bad governance and corruption particularly in the Northern part of Nigeria have been responsible for the persistent rise in the activities of Jama’atu Ahlis Sunna Lidda’awati wal-Jihad (JASLWJ, Arabic for “people committed to the propagation of the tradition and jihad.” It is also known as “Boko Haram,” commonly translated as “Western education is sin.” Based on qualitative data obtained through interviews with Nigerians, this article explicates how poor governance in the country has created a vicious cycle of corruption, poverty, and unemployment, leading to violence. Although JASLWJ avows a religious purpose in its activities, it takes full advantage of the social and economic deprivation to recruit new members. For any viable short- or long-term solution, this article concludes that the country must go all-out with its anti-corruption crusade. This will enable the revival of other critical sectors such as agriculture and manufacturing, likely ensuring more employment. Should the country fail to stamp out corruption, it will continue to witness an upsurge in the activities of JASLWJ, and perhaps even the emergence of other violent groups. The spillover effects may be felt not only across Nigeria but also within the entire West African region.

  3. Corruption kills: estimating the global impact of corruption on children deaths.

    Directory of Open Access Journals (Sweden)

    Matthieu Hanf

    Full Text Available BACKGROUND: Information on the global risk factors of children mortality is crucial to guide global efforts to improve survival. Corruption has been previously shown to significantly impact on child mortality. However no recent quantification of its current impact is available. METHODS: The impact of corruption was assessed through crude Pearson's correlation, univariate and multivariate linear models coupling national under-five mortality rates in 2008 to the national "perceived level of corruption" (CPI and a large set of adjustment variables measured during the same period. FINDINGS: The final multivariable model (adjusted R(2= 0.89 included the following significant variables: percentage of people with improved sanitation (p.value<0.001, logarithm of total health expenditure (p.value = 0.006, Corruption Perception Index (p.value<0.001, presence of an arid climate on the national territory (p = 0.006, and the dependency ratio (p.value<0.001. A decrease in CPI of one point (i.e. a more important perceived corruption was associated with an increase in the log of national under-five mortality rate of 0.0644. According to this result, it could be roughly hypothesized that more than 140000 annual children deaths could be indirectly attributed to corruption. INTERPRETATIONS: Global response to children mortality must involve a necessary increase in funds available to develop water and sanitation access and purchase new methods for prevention, management, and treatment of major diseases drawing the global pattern of children deaths. However without paying regard to the anti-corruption mechanisms needed to ensure their proper use, it will also provide further opportunity for corruption. Policies and interventions supported by governments and donors must integrate initiatives that recognise how they are inter-related.

    Science.gov (United States)

    Rispel, Laetitia C; de Jager, Pieter; Fonn, Sharon

    2016-03-01

    Recent scholarly attention has focused on weak governance and the negative effects of corruption on the provision of health services. Employing agency theory, this article discusses corruption in the South African health sector. We used a combination of research methods and triangulated data from three sources: Auditor-General of South Africa reports for each province covering a 9-year period; 13 semi-structured interviews with health sector key informants and a content analysis of print media reports covering a 3-year period. Findings from the Auditor-General reports showed a worsening trend in audit outcomes with marked variation across the nine provinces. Key-informants indicated that corruption has a negative effect on patient care and the morale of healthcare workers. The majority of the print media reports on corruption concerned the public health sector (63%) and involved provincial health departments (45%). Characteristics and complexity of the public health sector may increase its vulnerability to corruption, but the private-public binary constitutes a false dichotomy as corruption often involves agents from both sectors. Notwithstanding the lack of global validated indicators to measure corruption, our findings suggest that corruption is a problem in the South African healthcare sector. Corruption is influenced by adverse agent selection, lack of mechanisms to detect corruption and a failure to sanction those involved in corrupt activities. We conclude that appropriate legislation is a necessary, but not sufficient intervention to reduce corruption. We propose that mechanisms to reduce corruption must include the political will to run corruption-free health services, effective government to enforce laws, appropriate systems, and citizen involvement and advocacy to hold public officials accountable. Importantly, the institutionalization of a functional bureaucracy and public servants with the right skills, competencies, ethics and value systems and whose

    1982-09-01

    Access to two boreholes at the Carwynnen test site in Cornwall enabled the trial of a number of innovative approaches to the hydrogeology of fractured crystalline rock. These methods ranged from the use of seisviewer data to measure the orientation of fractures to the use of the sinusoidal pressure technique to measure directional hydraulic diffusivity. The testing began with a short programme of site investigation consisting of borehole caliper and seisviewer logging followed by some single borehole hydraulic tests. The single borehole hydraulic testing was designed to assess whether the available boreholes and adjacent rock were suitable for testing using the sinusoidal method. The main testing methods were slug and pulse tests and were analysed using the fissured porous medium analysis proposed in Barker and Black (1983). Derived hydraulic conductivity (K) ranged from 2 x 10 -12 m/sec to 5 x 10 -7 m/sec with one near-surface zone of high K being perceived in both boreholes. The results were of the form which is typical of fractured rock and indicated a combination of high fracture frequency and permeable granite matrix. The results are described and discussed. (author)

    Full Text Available One of the major problems in hip replacement surgery is the hip replacement loosening. Hip replacement loosening occurs over time after the surgery and it is related to the discretization between the bone cement and prosthesis. The underlying factors of this situation are the stress occurring in the bone cement and the shape of the prosthesis. In this study, cortical and trabecular layers of the femur, bone cement and prosthesis were modeled. The models of bone cement and prosthesis were constructed parametrically and two different sinusoidal formed prostheses were developed unlike the former prostheses shapes. Analyses were conducted for these two different sinusoidal forms by using finite element method and optimization was conducted to obtain the appropriate prosthesis stem shape and bone cement thickness by using parametric modeling in finite element analyses. For finite element analyses and optimization, Ansys Workbench software was used and analyses were conducted for 316LS stainless steel material. Finally, the optimum prosthesis stem shape and bone cement thickness was determined by using the results of the analyses in the first stage

  10. Corruption and the Other(s): Scope of Superordinate Identity Matters for Corruption Permissibility.

    Pisor, Anne C; Gurven, Michael

    2015-01-01

    The decision to engage in corruption-public and private corruption, nepotism, and embezzlement-is often attributed to rational actors maximizing benefits to themselves. However, the importance of reciprocal relationships in humans suggests that an actor may weigh the costs of harms of her corrupt behavior to individuals who may generate future benefits for her. We hypothesize that actors who have a larger circle of actual and potential social partners will have more individuals to consider when generating harms and will thus be less likely to find corrupt acts permissible than actors with smaller circles of valued others. Using data from the World Values Survey and European Values Study (WVS), we explore whether participants with a larger geographic identity or a greater number of group memberships (i.e. a larger scope of actual and potential social partners) are less likely to find accepting bribes permissible. We find mixed support for our hypotheses, but consistently find that WVS participants with local, country, continent, or world geographic identities are less likely to find accepting a bribe permissible than those with regional identities-that is, actors whose primary identities that encompass more than their region find corruption less permissible. We discuss the importance of considering an actor's valuation of others when modeling corruption persistence, noting that establishing scopes of positive valuation is a precursor to predicting where actors will target benefits and shunt costs.

    Full Text Available The decision to engage in corruption-public and private corruption, nepotism, and embezzlement-is often attributed to rational actors maximizing benefits to themselves. However, the importance of reciprocal relationships in humans suggests that an actor may weigh the costs of harms of her corrupt behavior to individuals who may generate future benefits for her. We hypothesize that actors who have a larger circle of actual and potential social partners will have more individuals to consider when generating harms and will thus be less likely to find corrupt acts permissible than actors with smaller circles of valued others. Using data from the World Values Survey and European Values Study (WVS, we explore whether participants with a larger geographic identity or a greater number of group memberships (i.e. a larger scope of actual and potential social partners are less likely to find accepting bribes permissible. We find mixed support for our hypotheses, but consistently find that WVS participants with local, country, continent, or world geographic identities are less likely to find accepting a bribe permissible than those with regional identities-that is, actors whose primary identities that encompass more than their region find corruption less permissible. We discuss the importance of considering an actor's valuation of others when modeling corruption persistence, noting that establishing scopes of positive valuation is a precursor to predicting where actors will target benefits and shunt costs.

    2015-01-01

    Full Text Available The present article is dedicated to the analysis of "corruption" from point of view of political practice and political theory. The present article studies historical examples of corruption: corruption during the era of Alexander the Great, Carthage, Roman Republic. The article gives the evolution of the term "corruption", pointing out current aspects of the term. The article provides positive and negative results of corruption, gives resume. The present article analyses corruption results: economical, political and social. Most important economical consequences of corruption are the following: increase of shadow economy, decrease of tax payments, weakening of the state budget, breach of market competition, decrease of market effectiveness, destabilization of the idea of market economy. Most important social consequences of corruption are the following: great distinction between the declared and real values, which creates a "double standard" of the moral and behavior, distraction of great sums from public and humanitarian development, increase of property disproportion, increase of social tension. The present article names most important political consequences of corruption: shift of ideas from public development to the security of power of oligarchy, decrease of trust to the state, decrease of image of the country at the international arena, increase of its economical and political isolation, decrease of political competition. The present article gives one of the resumes that the globalization process increases corruption. Together with globalization most important role is given to corporations and corporate corruption comes to the front raw.

  15. Harmonization Of Inter-Institutional Authority In Eradicate Corruption

    2015-08-01

    Full Text Available Nowadays the agenda of corruption eradication have been undertaken by various institutions such as the judiciary the police the Corruption Eradication Commission and other bodies related to the corruption eradication. The type of research used in this study is normative-jurisdiction and empirical-jurisdiction. To obtain the necessary data in this study the researcher conducted library research as a reference in some libraries are quite representative. Results shows that the effectiveness of corruption eradication that conducted by regulatory authorities in order to combat corruption has not been implemented maximally because each institution as a subsystem has not carried out an interdependent relationship both vertical and horizontal nature. If we expect the eradication of corruption can be implemented optimally it is recommended that the coordination between law enforcement agencies in the integrated criminal justice system is necessary to build their common vision interpretation and perception in the implementation of the duties for the institution authorized to eradicate corruption.

  16. POLITICAL PROCESS DRIVERS OF CORRUPTION IN EASTERN EUROPE

    Full Text Available Corruption stands as one of the many obstacles to the political and economic security of the Eastern European region. Thus, despite the political and economic instability in the region, Eastern European countries, in and outside of the European Union need to fight corruption collectively and individually. The task is difficult, but hope is justified because the causes of corruption in this part of the region are similar and anti-corruption expertise is available. We believe that a deeper analysis of corruption’s drivers can produce a better articulated and more efficient anti-corruption strategy. This strategy will create an anti-corruption infrastructure that will strengthen the Eastern European Partnership. As a prelude to the deeper analysis that we believe must be a part of this strategy, this paper identifies the main drivers of corruption in the Eastern European Partnership countries and explains why addressing these drivers will strengthen the Eastern European Partnership.

  17. Corruption and Stock Market Development: New Evidence from GCC Countries

    Directory of Open Access Journals (Sweden)

    Moaz Alsherfawi Aljazaerli

    2016-06-01

    Full Text Available The theoretical relationship between corruption and stock market development has been debated quite extensively in the literature, yet the evidence on the impact of corruption on stock market development remains contradictory and ambiguous. This paper investigates the impact of corruption, as measured by Corruption Perception Index (CPI published by Transparency International, on stock market development focusing exclusively on Gulf Cooperation Council (GCC countries with its special characteristics of combining richness with relatively high level of corruption. Results from an estimation of alternative regression models on a panel of six GCC countries over the period 2003–2011, through which CPI is legitimately comparable, confirms a positive impact of corruption on stock market development, where the latter is measured by market capitalization. This is consistent with the view that corruption greases the wheels of economy by expediting transactions and allowing private firms to overcome governmentally imposed inefficiencies.

  18. Preventing corruption in humanitarian assistance: perceptions, gaps and challenges.

    Maxwell, Daniel; Bailey, Sarah; Harvey, Paul; Walker, Peter; Sharbatke-Church, Cheyanne; Savage, Kevin

    2012-01-01

    Corruption is a threat to the purpose of humanitarian assistance. Until fairly recently, humanitarian assistance has not been considered an important arena in broader efforts aimed at curbing corruption, and corruption has not always been considered a particularly important concern for humanitarian assistance despite the obviously challenging nature of the context of humanitarian emergencies. Corruption, though, is a threat to humanitarian action because it can prevent assistance from getting to the people who most need it, and because it can potentially undermine public support for such assistance. This paper examines perceptions of corruption and its affects, documents best practices, and outlines gaps in understanding. It suggests recommendations for improving the capacity of humanitarian agencies to prevent and manage the risk of corruption. Agencies have taken steps to combat corruption and improve accountability--downwards and upwards--but scope remains for improvement and for greater sharing of learning and good practice. © 2012 The Author(s).

  19. Do Corruption and Social Trust affect Economic Growth? A Review

    DEFF Research Database (Denmark)

    Serritzlew, Søren; Sønderskov, Kim Mannemar; Svendsen, Gert Tinggaard

    2014-01-01

    Two separate literatures suggest that corruption and social trust, respectively, are related to economic growth, although the strengths of the relationships, and the direction of causality, are still debated. In this paper, we review these literatures and evaluate the evidence for causal effects...... of corruption and trust on economic growth, and discuss how corruption and trust are interrelated. The reviews show that absence of corruption and high levels of social trust foster economic growth. The literatures also indicate that corruption has a causal effect on social trust, while the opposite effect...... is more uncertain. In the conclusion, we offer the suggestion that fighting corruption may yield a “double dividend”, as reduced corruption is likely to have both direct and indirect effects on growth....

    2017-11-11

    The development of efficient and strategic anti-corruption measures can be better achieved if a deeper understanding and identification of the causes of corruption are established. Over the past years, many studies have been devoted to the research of corruption in construction management (CM). This has resulted in a significant increase in the body of knowledge on the subject matter, including the causative factors triggering these corrupt practices. However, an apropos systematic assessment of both past and current studies on the subject matter which is needful for the future endeavor is lacking. Moreover, there is an absence of unified view of the causative factors of corruption identified in construction project management (CPM). This paper, therefore, presents a comprehensive review of the causes of corruption from selected articles in recognized construction management journals to address the mentioned gaps. A total number of 44 causes of corruption were identified from 37 publications and analyzed in terms of existing causal factors of corruption, annual trend of publications and the thematic categorization of the identified variables. The most identifiable causes were over close relationships, poor professional ethical standards, negative industrial and working conditions, negative role models and inadequate sanctions. A conceptual framework of causes of corruption was established, after categorizing the 44 variables into five unique categories. In descending order, the five constructs are Psychosocial-Specific Causes, Organizational-Specific Causes, Regulatory-Specific Causes, Project-Specific Causes and Statutory-Specific Causes. This study extends the current literature of corruption research in construction management and contributes to a deepened understanding of the causal instigators of corruption identified in CPM. The findings from this study provide valuable information and extended knowledge to industry practitioners and policymakers as well as

  1. Systemic roots of corruption: Corruption and its perception: Reality vs. appearance

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Serbia is widely believed to be a country flooded with corruption. The question naturally arises as to what might be the causes of this unwelcome phenomenon. The basic stand extensively elaborated in this text is that the causes of the corruption are institutional, i.e. systemic. Without recourse to the systemic causes, the alternative would be that corruption arises from some special anthropological traits of this people. Upon rejecting such an explanation of corruptive practices, the institutional roots are further elaborated. Economic and other policies can also be conducive to corruption, but they are made in an environment structured in the spirit of public choice - policies themselves are motivated by the systemic peculiarities - so that the ultimate determinants are again to be sought in the institutional order of the given society. It might appear at first sight that corruption should be easy to eliminate, as institutions are man-made and not an unchangeable given coming from nature or some uncontrollable entity. However, institutional development is constrained by many factors - knowledge, competent people, information systems, real resources, and financial means - and it is argued that it can be as painful, uncertain, costly and slow as the economic development itself. The complexity of the corruption as an economic, social and even ethical phenomenon is demonstrated by the multiplicity of its definitions and by the conspicuous succession of alternative definitions in time. The problems of measurement are elaborated to some length. Corruption is illegal and therefore, unlike most economic aggregates, cannot be measured directly; it is the perception of the corruption rather than the corruption itself that is being measured in widely cited national and international surveys. The respondents are not centered exclusively at revealing the truth, but are subject to a wide variety of motivations. Some of them are motivated to overstate the

  3. Essays on environmental policies, corruption, and energy

    Science.gov (United States)

    Baksi, Soham

    This thesis consists of four essays. The first essay looks at pollution taxation under capital mobility, and analyzes the role of pre-commitment by countries to their pollution tax rate. A polluting firm sells its product in two countries, and can locate and produce in a single country or in both countries. Due to the discrete-choice nature of the firm's location problem, the countries' welfare functions are discontinuous in their pollution tax rate. We show that when the countries cannot pre-commit to their pollution tax, the firm can still engender tax competition between them by strategically locating in both the countries. Moreover, pre-commitment pollution taxation may not be welfare improving for the countries, although it always makes the firm better off. The second essay studies the effect of liberalization on corruption. Corruptible inspectors enforce an environmental regulation on firms, and are monitored by an honest regulator. Liberalization not only increases the variety of goods and the marginal utility of accepting a bribe, but also puts pressure on the regulator to curb corruption. The interaction of these two effects can cause corruption to initially increase with liberalization, and then decrease beyond a threshold. Moreover, equilibrium corruption is lower when the regulator is able to pre-commit to her monitoring frequency. The third essay analyzes optimal labeling (information revelation) procedures for hidden attributes of credence goods. Consumers are heterogeneous in their preference for the hidden attribute, and producers can either self-label their products, or have them certified by a third party. The government can impose self or third-party labeling requirements on either the "green" or the "brown" producers. When corrupt producers can affix spurious labels, the government needs to monitor them. A mandatory self-labeling policy is shown to generally dominate mandatory third-party labeling. The fourth essay develops formulas for

    Corruption has been described as a disease. When corruption infiltrates global health, it can be particularly devastating, threatening hard gained improvements in human and economic development, international security, and population health. Yet, the multifaceted and complex nature of global health corruption makes it extremely difficult to tackle, despite its enormous costs, which have been estimated in the billions of dollars. In this forum article, we asked anti-corruption experts to identify key priority areas that urgently need global attention in order to advance the fight against global health corruption. The views shared by this multidisciplinary group of contributors reveal several fundamental challenges and allow us to explore potential solutions to address the unique risks posed by health-related corruption. Collectively, these perspectives also provide a roadmap that can be used in support of global health anti-corruption efforts in the post-2015 development agenda.

    2011-09-01

    Full Text Available Since eradicating corruption having been continously encouraged by late governments – and until now – , there would not be less important as to retracting the corrupted assets. There are many aspects to be considered in doing such action, such as manifesting the legal aspects of administrative law, and so other applied national regulations. By these regulations, such as Law No. 7 of 2006 on Ratification of United Nations Convention against Corruption, 2003 (Konvensi Perserikatan Bangsa Bangsa Anti-Korupsi, 2003, Law Number 25 of 2003 On Amendment to Law Number 15 of 2002 on Money Laundering, Act 30 of 2002 on Corruption Eradication Commission, Law Number 20 Year 2001 regarding Amendment to Law Number 31 Year 1999 on the Eradication of Corruption, and Government Regulation Number 65 of 1999 on Implementation Procedures for Examination of State Property, retraction the corrupted assets should be define in order to get known about eradicating corruption.

    The paper theoretically explores the impact of introducing bureaucratic competition on corruption. For this purpose it considers three different measures of corruption such as corruption incidence (CI), relative corruption incidence (CRI) and corruption rents (CR) in two different types of economies namely corruption-tolerant economies and corruption-reliant economies. As it compares both intensive margin (i.e. the magnitude of bribe) and extensive margin (i.e. the number of bribe incident) o...

    Full Text Available ABSTRACT Objective Dyslexia is the difficulty of children in learning to read and write as results of neurological deficiencies. The objective was to test the Phonological awareness (PA and Sinusoidal amplitude modulation (SAM threshold in children with Phonological dyslexia (PD. Methods We performed a case-control, analytic, cross sectional study. We studied 14 children with PD and 14 control children from 7 to 11 years of age, by means of PA measurement and by SAM test. The mean age of dyslexic children was 8.39 years and in the control group was 8.15. Results Children with PD exhibited inadequate skills in PA, and SAM. We found significant correlations between PA and SAM at 4 Hertz frequency, and calculated regression equations that predicts between one-fourth and one-third of variance of measurements. Conclusion Alterations in PA and SAM found can help to explain basis of deficient language processing exhibited by children with PD.

    Full Text Available Current-mode (CM and voltage-mode (VM multiphase sinusoidal oscillator (MSO structures using current backward transconductance amplifier (CBTA are proposed. The proposed oscillators can generate n current or voltage signals (n being even or odd equally spaced in phase. n+1 CBTAs, n grounded capacitors and a grounded resistor are used for nth-state oscillator. The oscillation frequency can be independently controlled through transconductance (gm of the CBTAs which are adjustable via their bias currents. The effects caused by the non-ideality of the CBTA on the oscillation frequency and condition have been analyzed. The performance of the proposed circuits is demonstrated on third-stage and fifth-stage MSOs by using PSPICE simulations based on the 0.25 µm TSMC level-7 CMOS technology parameters.

  10. New Realizations of Single OTRA-Based Sinusoidal Oscillators

    Directory of Open Access Journals (Sweden)

    Hung-Chun Chien

    2014-01-01

    Full Text Available This study proposes three new sinusoidal oscillators based on an operational transresistance amplifier (OTRA. Each of the proposed oscillator circuits consists of one OTRA combined with a few passive components. The first circuit is an OTRA-based minimum RC oscillator. The second circuit is capable of providing independent control on the condition of oscillation without affecting the oscillation frequency. The third circuit exhibits independent control of oscillation frequency through a capacitor. This study first introduces the OTRA and the related formulations of the proposed oscillator circuits, and then discusses the nonideal effects, sensitivity analyses, and frequency stability of the presented circuits. The proposed oscillators exhibit low sensitivities and good frequency stability. Because the presented circuits feature low impedance output, they can be connected directly to the next stage without cascading additional voltage buffers. HSPICE simulations and experimental results confirm the feasibility of the new oscillator circuits.

  12. Surface wave propagation over sinusoidally varying topography: Theory and observation

    Science.gov (United States)

    Davies, A. G.; Heathershaw, A. D.

    Linear perturbation theory is used to show that the reflection coefficient of a patch of sinusoidal ripples on an otherwise flat bed is oscillatory in the quotient of the length of the patch and the surface wave length, and strongly dependent upon the quotient of the surface and bed wave numbers. Resonant interaction between the surface waves and the ripples if the surface wavenumber is half the ripple wavenumber is demonstrated. Few ripples, of relatively small steepness, are required to produce a substantial reflected wave. In resonant cases, the partially standing wave on the up-wave side of the ripple patch gives way, in an almost linear manner over the the ripple patch itself, to a progressive (transmitted) wave on the down-wave side. Wave tank data agree well with predictions, and suggest coupling between wave reflection and ripple growth on an erodible bed.

  13. Representative Sinusoids for Hepatic Four-Scale Pharmacokinetics Simulations.

    Directory of Open Access Journals (Sweden)

    Lars Ole Schwen

    Full Text Available The mammalian liver plays a key role for metabolism and detoxification of xenobiotics in the body. The corresponding biochemical processes are typically subject to spatial variations at different length scales. Zonal enzyme expression along sinusoids leads to zonated metabolization already in the healthy state. Pathological states of the liver may involve liver cells affected in a zonated manner or heterogeneously across the whole organ. This spatial heterogeneity, however, cannot be described by most computational models which usually consider the liver as a homogeneous, well-stirred organ. The goal of this article is to present a methodology to extend whole-body pharmacokinetics models by a detailed liver model, combining different modeling approaches from the literature. This approach results in an integrated four-scale model, from single cells via sinusoids and the organ to the whole organism, capable of mechanistically representing metabolization inhomogeneity in livers at different spatial scales. Moreover, the model shows circulatory mixing effects due to a delayed recirculation through the surrounding organism. To show that this approach is generally applicable for different physiological processes, we show three applications as proofs of concept, covering a range of species, compounds, and diseased states: clearance of midazolam in steatotic human livers, clearance of caffeine in mouse livers regenerating from necrosis, and a parameter study on the impact of different cell entities on insulin uptake in mouse livers. The examples illustrate how variations only discernible at the local scale influence substance distribution in the plasma at the whole-body level. In particular, our results show that simultaneously considering variations at all relevant spatial scales may be necessary to understand their impact on observations at the organism scale.

    Petrinović, Davor; Brezović, Marko

    2011-04-01

    We propose a method for direct digital frequency synthesis (DDS) using a cubic spline piecewise-polynomial model for a phase-to-sinusoid amplitude converter (PSAC). This method offers maximum smoothness of the output signal. Closed-form expressions for the cubic polynomial coefficients are derived in the spectral domain and the performance analysis of the model is given in the time and frequency domains. We derive the closed-form performance bounds of such DDS using conventional metrics: rms and maximum absolute errors (MAE) and maximum spurious free dynamic range (SFDR) measured in the discrete time domain. The main advantages of the proposed PSAC are its simplicity, analytical tractability, and inherent numerical stability for high table resolutions. Detailed guidelines for a fixed-point implementation are given, based on the algebraic analysis of all quantization effects. The results are verified on 81 PSAC configurations with the output resolutions from 5 to 41 bits by using a bit-exact simulation. The VHDL implementation of a high-accuracy DDS based on the proposed PSAC with 28-bit input phase word and 32-bit output value achieves SFDR of its digital output signal between 180 and 207 dB, with a signal-to-noise ratio of 192 dB. Its implementation requires only one 18 kB block RAM and three 18-bit embedded multipliers in a typical field-programmable gate array (FPGA) device. © 2011 IEEE

  15. Using spatiotemporal source separation to identify prominent features in multichannel data without sinusoidal filters.

    Cohen, Michael X

    2017-09-27

    The number of simultaneously recorded electrodes in neuroscience is steadily increasing, providing new opportunities for understanding brain function, but also new challenges for appropriately dealing with the increase in dimensionality. Multivariate source separation analysis methods have been particularly effective at improving signal-to-noise ratio while reducing the dimensionality of the data and are widely used for cleaning, classifying and source-localizing multichannel neural time series data. Most source separation methods produce a spatial component (that is, a weighted combination of channels to produce one time series); here, this is extended to apply source separation to a time series, with the idea of obtaining a weighted combination of successive time points, such that the weights are optimized to satisfy some criteria. This is achieved via a two-stage source separation procedure, in which an optimal spatial filter is first constructed and then its optimal temporal basis function is computed. This second stage is achieved with a time-delay-embedding matrix, in which additional rows of a matrix are created from time-delayed versions of existing rows. The optimal spatial and temporal weights can be obtained by solving a generalized eigendecomposition of covariance matrices. The method is demonstrated in simulated data and in an empirical electroencephalogram study on theta-band activity during response conflict. Spatiotemporal source separation has several advantages, including defining empirical filters without the need to apply sinusoidal narrowband filters. © 2017 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.

  16. Sinusoidal Parameter Estimation Using Quadratic Interpolation around Power-Scaled Magnitude Spectrum Peaks

    Directory of Open Access Journals (Sweden)

    Kurt James Werner

    2016-10-01

    Full Text Available The magnitude of the Discrete Fourier Transform (DFT of a discrete-time signal has a limited frequency definition. Quadratic interpolation over the three DFT samples surrounding magnitude peaks improves the estimation of parameters (frequency and amplitude of resolved sinusoids beyond that limit. Interpolating on a rescaled magnitude spectrum using a logarithmic scale has been shown to improve those estimates. In this article, we show how to heuristically tune a power scaling parameter to outperform linear and logarithmic scaling at an equivalent computational cost. Although this power scaling factor is computed heuristically rather than analytically, it is shown to depend in a structured way on window parameters. Invariance properties of this family of estimators are studied and the existence of a bias due to noise is shown. Comparing to two state-of-the-art estimators, we show that an optimized power scaling has a lower systematic bias and lower mean-squared-error in noisy conditions for ten out of twelve common windowing functions.

    2018-03-15

    Corruption in healthcare generally and specifically in the pharmaceutical arena has recently been highlighted in reports by Transparency International. This article focuses on four areas of corruption: legislative/regulatory, financial, ideological/ethical, and communications. The problems identified and the solutions considered focus on structural considerations affecting how pharmaceuticals are discovered, developed, distributed, and ultimately used in clinical settings. These include recourse to user fees in the regulatory sphere, application of intellectual property rights to medical contexts (patents and access to research data), commercial sponsorship of ghost writing and guest authors, linkage/delinkage of the funding of research and overall health objectives to/from drug pricing and sales, transparency of payments to healthcare professionals and institutions, and credible regulatory sanctions. In general, financial and other incentives for all actors in the system should be structured to align with desired social outcomes - and to minimise conflicts of interest among researchers and clinicians.

    Full Text Available This paper analyses the scale and sources of views on the prevalence of corruption in the education sector in Poland. Through the use of public opinion surveys, I answer questions on how the corruption level in Polish educational institutions has changed over time and how it compares to other public institutions (such as the health care sector and police and to the situation in other European countries. My goal is to investigate the effect of individual-level predictors of perceiving schools as corrupt in Poland, with special attention given to structural determinants and previous bribe-giving experiences of respondents. The results reveal that in Poland relatively few respondents have experienced recent acts of giving bribes in schools or perceive educational institutions as corrupt. However, there is a structural pattern behind the sources of negative opinions. The effect of socio-economic determinants on views relating to corruption in Polish schools is strongly pronounced and trends in the opposite direction compared to the effects reported in other European countries.
